In embodiments the control circuit 17 may be a discrete circuit. In embodiments, the control circuit 17 may be a microprocessor or other programmable logic device. While FIG. 5B illustrates the inclusion of the control circuit 17, it is noted that a control circuit is not required. In embodiments, the heating element 12f may remain active after the switch 12a is actuated until the switch 12a is actuated a second time to deactivate the heating element 12f. In embodiments, actuating the switch 12a a second time may reset a timer used to control the heating element 12f to keep the heating element 14a active for a longer period of time. While the term “switch” is used, element 12a may be any input element including but not limited to a button, switch or touchpad, to name a few. In embodiments, the heating element 12f may be connected to a heating circuit 12h that may control activation of the heating element 12f in a desired pattern based on input from the switch 12a or the control circuit 17 for example. While the heating circuit 12h is illustrated in the block diagrams of FIG. 5A and 5B, it is noted that the heating circuit 12h is not necessary and the heating element 12f may be driven directly by the switch 12a or control circuit 17. In embodiments, the heating circuit 12h may be provided on printed circuit board 12g provided on the base 12. In embodiments, the heating element 12f may be turned on and off over a period of time to provide for a desired pattern of heating. In embodiments, the switch 12a, may be connected to the heating circuit 12h to begin or terminate such a desired heating pattern.

In embodiments, activation of the switch 12a, may begin the pattern of activating the heating element 12f and deactivating it to provide a desired level of heating. In embodiments, one or more fans may be electrically connected to the switch 12a and/or the control circuit 17 and selectively activated to blow vaporized insect repellent material M out of the vaporizer device 10. In embodiments the one or more fans may operate only when the heating element 12f is activated. In embodiment, the fan(s) may operate when the heating element 12f is activated and for a period of time before and/or after the heating element 12f is deactivated. In embodiments, the fan(s) may operate in a pattern that may be based on the heating pattern provided by the heating circuit 12h or the control circuit 17. In embodiments, the switch 12a may be or may be connected to the control circuit 17, which may be a programmable device, such as a microprocessor or other programmable logic device, that may be used to control the heating element 12f in accordance with a set of commands or rules to provide the heating pattern or otherwise. In embodiments, the heating circuit 12h may be or include the control circuit 17. In embodiments the heating circuit 12h may include one or more discrete circuit elements or may be implemented on a printed circuit board such as the PCB 12g. In embodiments the control circuit 17 may also be implemented on or mounted on the PCB 12g. In embodiments, the heating element 12f may include the one or more timers discussed above that may be used to control activation and deactivation of the heating element 12f. [0055] In embodiments, the cartridge 14 may include a protrusion 14g that extends downward into a top portion of the base 12 (see FIG. 4 A, for example). A metal plate 14f may be provided in contact with the heating element 12f and the protrusion 14g of the cartridge. In embodiments, the metal plate 14f may be heated by the heating element 12f of the base 12 when the cartridge 14 is mounted on the base and transfers heat to the protrusion 14g. In embodiments, the metal plate 14f may be attached to the protrusion 14g. In embodiments, the metal plate 14f may be attached to the base 12. In embodiments, the insect repellent material M may be provided in the cartridge 14 and may be heated via the metal plate 14f and protrusion 14g. In embodiments, heating of the metal plate 14f heats the protrusion 14g and the insect repellent such that the insect repellent vaporizes and escapes out the openings 14a in the top of the cartridge 14. In embodiments, the fan(s) may be mounted in the cartridge 14 to blow the vaporized insect repellent out of the openings 14a. In embodiments, the protrusion 14g may directly contact the heating element 12f to provide heat to vaporize the insect repellent material. In embodiments, the protrusion 14g may be positioned adjacent to the heating element 12f.

[0056] In embodiments, the cartridge 14 may be removably attached to the base 12. In embodiments, the protrusion 14g at the bottom of the cartridge 14 may include one or more first fastening elements 14e to removably mount the cartridge to the base 12. In embodiments, the top surface of the metal plate 14f may include one or more second fastening elements 12e to cooperate with the first fastening elements to removably mount the cartridge 14 on the base. In this embodiment, the metal plate 14f is part of and secured within the base 12. In embodiments, the first fastening elements 14e and second fastening elements 12e may be complimentary magnetic elements that attract each other to connect the cartridge 14 to the base 12. In embodiments the first fastening elements 14e and second fastening elements 12e may include any suitable fastening structure that allows for removable mounting of the cartridge 14 on the base 10. In embodiments, the fastening elements 14e and 12e may be connected using a snap fit connection. In embodiments, the fastening elements 14e and 12e may be connected using twist lock connection, however, any suitable connecting structure may be used.

[0057] In operation, as noted above, a user may activate the switch 12a to begin operation of the device 10. In embodiments, actuation of the switch 12a may activate the heating element 12f, which, in turn, heats the metal plate 14f and/or the protrusion 14g as well as the insect repellent material M in the cartridge 14 to vaporize it. In embodiments, the plate 14f need not be metal provided that it is made of a material that is a good conductor of heat. That is, in embodiments, the plate 14f may be made of any thermally conductive material. In embodiments, the protrusion 14g may also be made of a thermally conductive material. In embodiments, the protrusion 14g may directly contact or be positioned adjacent to the heating element 12f such that the plate 14f may be not be used. The vaporized insect repellent material M may escape via the openings 14a. In embodiments, the activation of the switch 12a may also activate the one or more fans to aid in dispersal of the vaporized insect repellent around the device 10. In embodiments, as the vaporized repellent spreads out of the openings 14a and around the device 10, it provides an area of vaporized repellent around the device. This area will generally be substantially insect free. As noted above, the switch 12a may be used in conjunction with one or more timers or other control elements which may be provided in or connected to the heating circuit 12h, or the control circuit 17, to control activation of the heating element 12f to control vaporization of the insect repellent material M to maintain or expand the insect free area of vaporized repellent. In embodiments, the switch 12a may be used to deactivate the heating element 14f or to reset the one or more timers. In embodiments, the heating element 14f will deactivate automatically once the timer counts down to 0 (or up to the predetermined time limit). In embodiments, the heating element 12f may be turned on and off in a desired pattern upon actuation of the switch 12a, for example based on the operation of heating circuit 12h or control circuit 17 or other programmable device or controller, for example, which may be provided on printed circuit board 12g, or elsewhere. In embodiments, the power source 30 may also power the heating circuit 12h and/or programmable device or controller such as the control circuit 17. In embodiments, the switch 12a may be embodied as any suitable input device such as a button, slider, or selector to name a few.

[0058] When all, or substantially all of the insect repellent material M in the cartridge 14 is vaporized, the cartridge may be removed and replaced. In embodiments, the cartridge 14 may be removed, refilled with insect repellent material M and then placed back on the base 12. In embodiments, the cartridge 14 may be removed and replaced with a second cartridge having the same construction as the cartridge 14. [0059] In embodiments, a vaporizer device 110 may includes an insect repellent cartridge

114 removably mounted on a base 112 as illustrated in FIGs. 6-10. In embodiments, the cartridge 114 may include a wick 115 in contact with the insect repellent material M in the cartridge 114 as indicated in FIG. 9, for example. The insect repellent material M may travel along the wick 115 into the base 112. In embodiments, the base 112 includes a receptacle or opening 115a (see FIG. 9A, for example) formed in the heating element 112f that receives the wick 115 when the cartridge 114 is mounted on the base 112. In embodiments, the base 112 may include one or more heating element(s) 112f mounted therein to heat the wick 115. As the wick

115 is heated, the insect repellent material M therein vaporizes and escapes through the openings 114a in the base 112. In embodiments, the heating element 112f in the base 112 may be operated by actuation of the switch 112a in substantially the same manner as the heating element 12f operates upon actuation of the switch 112a as discussed above and a heating circuit 12h or control circuit 17 may be used in substantially the same manner as described above. In embodiments, a charging socket 112b may be provided in the base 112 to recharge a power source 130 mounted therein that powers the heating element 112f. In embodiments, the power source 130 may be similar in structure and function to the power source 30 discussed above. In embodiments, the cartridge 114 may be removably mounted on the base 112 using fastening members 114e, 112e in substantially the same manner as the cartridge 14 is connected to the base 12 using the first and second fastening member 14e, 12e. In this embodiment, the fastening member 114e may be provided on a bottom surface of the protrusion 114e and the fastening members 112e may be formed on or attached to the heating element 112f. In this embodiment, a conductive plate between the protrusion 114g and the heating element 112f is not necessary since heat need not be transferred to the protrusion 114g. In embodiments, a heating circuit or control circuit similar to the heating circuit 12h or control circuit 17, respectivey, may be provided to interact with the switch 112a in much the same manner as that described above with respect to switch 12a. In embodiments, the heating circuit may be provided on PCB 112g. The switch 112a may be connected to the power source 130 and heating element 112f (as well as the heating circuit and/or control circuit 17) in substantially the same manner as indicated in FIGS. 5A and 5B.

[0060] In operation, the user may actuate the switch 112a to activate the heating element

112f in the base 112. The heating element 112f in the base 112 may be provided adjacent to or otherwise close to the wick 115 extending through the receptacle 115a and into the base 112 from the cartridge 114. In embodiments, the wick 15 need not extend throught he receptacle but may be positioned adjacent or otherwise in close proximity to it. The switch 112a may control the heating element 112f in the base 112 in much the same manner as heating element 12f is controlled by the switch 12a as described above. The heat from the heating element 112f vaporizes the insect repellent material M in the wick 115. The vaporized insect repellent exits the device 110 via the openings 114a formed in the base 112. The openings 114a are illustrated as formed in the front surface of the base 112, however may be provided elsewhere if desired. The vaporized repellent material spreads outward to provide an area of vaporized repellent around the device 110 that is substantially insect free. In embodiments, one or more fan(s) may be provided in the base 112 to spread the vaporized insect repellent materia. In embodiments, the fan(s) may be controlled by actuation of the switch 112a and/or by the control circuit in the manner described above with respect to the switch 12a.

[0061] In another embodiment, such as that illustrated in FIGs. 11-15, an electric vaporizer device 210 may include an insect repellent cartridge 214 removably mounted on a base 212. In embodiments, the base 212 may include a power supply 250 (see FIG. 14A, for example), which may be structured and may function in substantially the same manner as the power supply 30. In embodiments, the insect repellent cartridge 214 may include a supply of insect repellent material M. In embodiments, the cartridge 214 may include one or more heating elements 230 mounted therein, adjacent to, near, or in the insect repellent material M. In embodiments, the base 212 may include a switch 212a that may be used to activate and/or deactivate the heating element 230. In embodiments, the top surface of the base 212 may include one or more electrical contacts 220 which are electrically connected to the power supply 250 in the base 212. In embodiments, a bottom surface of the cartridge 214, or the protrusion 214g, may include one or more complimentary contact(s) 222 (see FIG. 15, for example) to provide power to the heating element 230 from the first contact 220, for example. In embodiments, the switch 212a may activate the heating element 230, via the contacts 220, 222, in much the same manner as the switched 12a, 112a activate the heating elements 12f, 112f. In embodiments the cartridge 214 may include first fastening elements 214e that cooperate with second fastening elements 212e to removably fasten the cartridge 214 to the base 212. These fastening elements 214e, 212e may be the same or different than the fastening element 14e, 114e and 12e, 112e discussed above. In embodiments, a charging port 212b may be provided in the base 212 to allow for recharging of the power source 250 in the base 212 or to provide direct power in much the same manner described above with respect to the port 12b, 112b. The switch 212a may be connected to the power source 250 and heating element 230 (via the contacts 220, 222) in substantially the same manner as the switch 12 is connected to the power source 30 and the heating element 12f indicated in FIG. 5 A. In embodiments, a heating circuit or control circuit may be used to control operation of the heating element 230 in much the same manner as the heating circuit 12h discussed above. In embodiments, the heating circuit may be provided on the PCB 212g, for example. In embodiments a control circuit similar to control circuit 17 discussed above may be included and connected to the power source 250, the switch 212a, the heating element 230 and/or the heating circuit. The control circuit may be implemented and may function in the manner described above with respect to the control circuit 17 to control activation of the heating element 230 via the contacts 220, 222.

[0062] In operation, a user may actuate the switch 212a to activate the heating element

230 which will heat the insect repellent material M in the cartridge 214. As noted above, the switch 212a may actuate the heating element 230 via the contacts 220, 222, for example, in much the same manner as switch 12a actuates the heating element 12f.
