[0006] The advantages of the present invention will become readily apparent from the detailed description of various embodiments below.

[0007] Referring to FIG. 1 , a personal cleaning device 100 is shown. The device 100 may include an internal housing 101 having a top portion 102 and a bottom portion 103. The top portion 102 and/or the bottom portion 103 may be constructed of a rigid or semi-rigid plastic material (e.g., injection-molded or 3D printed thermoplastics such as Acrylonitrile Butadiene Styrene (ABS), Polyethylene terephthalate (PET), Polypropylene (PP), and the like). The top portion 102 and/or the bottom portion 103 may define a recess 104 and may be coupled to form the housing 101. In one embodiment, the top portion 102 may define a flanged portion 105 which may be configured to be received within and fictionally engage a perimeter wall 106 of the bottom portion 103 so as to couple the top portion 102 and the bottom portion 103. [0008] The device 100 may further include an electric motor 107 operably coupled to a control circuitry board 108 and at least one battery (not shown). The electric motor 107 may include a vibrational component (not shown), the movement of which is configured to induce vibration in the device 100 as a whole. For example, the vibrational component may include a mass coupled to a rotating drive shaft defining an axis 109 of the electric motor 107. The mass may be asymmetrically distributed around the axis 109 such that rotation of the vibrational component about the axis 109 may cause vibration of the device 100. Referring to FIG. 3, the axis 109 may be oriented such that it points generally in a direction of a front corner 110 of the device

100 configured to receive a sponge insert 111 , as will be described further below. In other embodiments, the vibrational component may be any other electrically powered rotational or oscillating structure configured to induce vibration in the device 100. The vibrational component may cause vibration of the device 100 at sonic frequencies (e.g., above 200 Hz) up to ultrasonic frequencies (e.g., at or above 1.6 MHz). Rotational vibration induced via the vibrational component around the axis 109 may serve to optimize cleansing using the front comer 110 as high-frequency, circular motion of the front corner 110 may be focused on a particular surface (e.g. a facial surface) to be cleaned.

[0099] The device 100 may include an external body 112. The external body 112 may be constructed of a semi-rigid or elastomeric material (e.g., silicone). The external body 112 may include an aperture 113 configured to receive and frictionally retain the bottom portion 103 of the housing 101. Further, the top portion 102 of the housing

101 may include a projecting portion 114 which may be received into and be frictionally retained within a recess defined by a cover 115.

[0010] Referring to FIG. 2, the control circuitry board 108 may include one or more user interface components (e.g., one or more switches or buttons) configured to allow user control of the activation and/or speed of vibration of the device 100 induced by the electric motor 107. For example, the control circuitry board 108 may be coupled to a power switch 116. Referring again to FIG. 1 , the top portion 102 of the housing 101 may include a corresponding actuatable button 117 formed in a top surface of the top portion 102 of the housing 101. Additionally, a pressure pad 118 may be formed in a top surface of the cover 115. Upon an application of pressure to the pressure pad 118 by a user, a corresponding pressure may be applied to the button 117 which may then contact the power switch 116 thereby activating the electric motor 107.

[0011] Similarly, referring again to FIG. 2, the control circuitry board 108 may include a speed control switch 119. The top portion 102 of the housing 101 may include a corresponding actuatable button (not shown) formed in a top surface of the top portion 102 of the housing 101. Additionally, a pressure pad 120 may be formed in the top surface of the cover 115. Upon an application of pressure to the pressure pad 120 by a user, a corresponding pressure may be applied to the button which may then contact the speed control switch 119 thereby changing a vibrational speed of the electric motor 107. Subsequent activations of the speed control switch 119 may progressively change the vibrational speed of the electric motor 107, for example, from a high speed to a medium speed to a low speed then returning to the high speed. Any number of different speeds and speed change increments may be employed without departing from the scope of the present disclosures.

[0012] As noted above, the device 100 may be configured to receive a sponge insert

111. Referring to FIGs. 1 and 3-6, the external body 112 may define a recess 121 configured to receive a portion of the sponge insert 111. For example, the recess 121 may be configured as a channel in the external body 112 which passes from a first rear corner of the external body 112, around the front corner 1 10 of the external body

112, to a right rear corner of the external body 112. As shown in FIG. 1 , the sponge insert 111 may have a U-shape or V-shape corresponding to a perimeter of the device 100 into which the recess 121 is formed. However, other shapes for the perimeter of the device 100, recess 121 and sponge insert 111 (e.g., rectilinear, rounded, enclosed circular, etc.) may be employed without departing from the scope of the present disclosures.

[0013] Referring to FIGs. 3-4, one or more flexible fibrous projections 122 may extend from the top and/or bottom interior surface of the recess 121 . Referring to FIGs. 4-7, progressive insertion of the sponge insert 111 into the recess 121 of the external body 112 is shown. As shown in FIG. 4, as the sponge insert 111 is inserted into the recess 121 , the fibrous projections 122 may flex to apply additional pressure the surface of the sponge insert 111 and/or interact with the pores of the sponge insert 111 so as to secure the sponge insert 111 within the recess 121 . [0014] As shown in FIGs. 5 and 7, upon full insertion of the sponge insert 111 into the recess 121 , a cleansing solution (e.g., a tea tree based natural cleanser), may be applied to the sponge insert 111. As shown in FIG. 6, the sponge insert 111 may be constructed of any biocompatible material that will expand upon an application of a liquid. For example, the sponge insert 111 may include products such as those marketed by Absorene Manufacturing Company, Inc. of St. Louis, Missouri. Such expansion of the sponge insert 111 may serve to further secure the sponge insert 111 within the recess 121 and provide additional working surface area of the sponge insert 111 to be used when a user performs personal cleansing. Further, as noted above, the sponge insert 111 may have a form factor (e.g., a rounded V-shape) which provides at least one corner 123 corresponding to the front comer 110 of the external body 112. Such a form factor provides a perimeter shape of the sponge insert 111 which allows a user to bring the device 100 into contact with the varying surfaces of a user’s face. Specifically, the sponge insert 111 may be dimensioned to have a rounded corner having a sufficiently small profile (e.g., as a function of the pointedness of the edges of the sponge insert 111 ) to effectively contact a user's meibomian glands, nasal sidewall, nasal sura-alar crease, medial and lateral canthus, and eyelids.
