TECHNICAL FIELD

The present invention relates to hair curler, and particularly relates to a baffle mechanism of a hair curler.

BACKGROUND ART

A hair curler is a handheld electronic product used for curling hair, and a conventional hair curler generally includes a handle and a heating curling barrel. A heating portion is exposed outside, which easily causes scald when using the conventional hair curler.

Generally, the handle extends out from one end of a shell, and the shell surrounds the heating curling barrel to form a hair guide space between the heating curling barrel and the shell so as to guide hair, so that the hair is conveniently placed inside the hair curler and can be prevented from releasing from the hair curler when being curled. However, the guide space is easily blocked because the hair easily scatters and tangles when gradually curled in the guide space, resulting in incapability of continuously curling the hair, thus causing a high failure rate and great inconvenience during the hair curling operation.

SUMMARY OF THE INVENTION

To overcome the drawback of the prior art, an objective of the present invention is to provide a baffle mechanism of a hair curler, which can be used to improve hair curling efficiency.

The objective of the present invention is achieved by the following technical solution: a baffle mechanism of a hair curler, which is configured to be installed in a shell of the hair curler and positioned outside a heating curling barrel of the hair curler, and the baffle mechanism comprises: a switch; an actuator, which is positioned in the shell and provided with a movable push rod and an electromagnet which is configured to drive the movable push rod to make a movement after being energized, wherein the movable push rod penetrates the electromagnet, and the electromagnet is electrically connected with the switch; and a baffle, which is connected to the end portion of the movable push rod and arranged opposite to the heating curling barrel.

Preferably, the baffle is a straight plate or arc plate.

Compared with the prior art, the present invention has the following advantageous effects.

The press switch enables the electromagnet of the telescopic apparatus to be energized, so as to drive the movable push rod to make a telescopic movement, as a result of which the baffle may move in a direction such that it is close to the heating curling barrel and in a direction away from the heating curling barrel under the pushing action of the push rod, thus enabling the baffle to be limited in position so as to play a role in baffling the hair, to ensure that the hair may be firmly curled on the heating curling barrel and prevented from rotating by 360 degrees when using the hair curler, so as to avoid hair tangling and blocking of the guide space as well as facilitate effective curling and styling of the hair and further improve hair curling efficiency.

The present invention is further explained in detail below in conjunction with the accompanying drawings and the detailed description.

DETAILED DESCRIPTION OF THE INVENTION

A baffle mechanism of a hair curler as shown in FIG. 1 to FIG. 2 is configured to be installed in a shell 100 of the hair curler and positioned outside a heating curling barrel 200 of the hair curler, and a guide space 300 is formed between the shell 100 and the heating curling barrel 200. The baffle mechanism comprises: a key 1 exposed out from the shell 100; a press switch 2 positioned in the shell 100 and elastically connected with the key 1 ; an actuator formed by a telescopic apparatus positioned in the shell 100 and provided with a movable push rod 3 and an electromagnet 4 which is configured to drive the movable push rod 3 to make a telescopic movement after being energized, wherein the movable push rod 3 penetrates the electromagnet 4, and the electromagnet 4 is electrically connected with the press switch 2; a baffle 6 located on the side of the heating curling barrel 200 and pivotally connected with the shell 100; and a baffle 6 connected to the end portion of the movable push rod 3 and arranged opposite to the heating curling barrel 200.

As shown in FIG. 1, after the key 1 is pushed, the press switch 2 is triggered to turn on a power supply to ensure that the electromagnet 4 is energized, and furthermore the movable push rod 3 is pushed towards the heating curling barrel 200 to enter the guide space 300 until the baffle 6 is pushed to a specified position (this pre-defined position may be preset) and connected with the heating curling barrel 200 so as to perform scraping, baffling, extruding and limiting the hair movement in the hair curling operation and preventing the hair from rotating by 360 degrees. The telescopic apparatus used in this embodiment may employ an apparatus in which a conventional electromagnet drives the movable push rod to make a telescopic movement by virtue of an attracting function, but may also employ a one-way high-speed electromagnet push rod apparatus as described in application number CN200420006371.2 of China utility model patent disclosure, and may also employ a motor-driven gear or other electronically-driven means, to achieve the same function.

As shown in FIG. 2, after the key 1 is pushed again, the press switch 2 turns off the power supply to ensure that the electromagnet 4 is de-energized, and the movable push rod 3 is retracted and drives the baffle 6 to be repositioned.

Preferably, the baffle 6 is a straight plate or arc plate, and may also provide for limiting and baffling the hair. Certainly, the baffle 6 may also be shaped differently and still be capable of baffling the hair.

The hair curler further comprises mechanism to detect hair trap problem. The motor, which drives the part curling the length of hair into the shell 100, and which is usually a brushless DC motor (BLDC), is configured to periodically send pulse signals to a controller. Preferably, the motor send such signals at a specific frequency, the rotation speed of the motor is known or can be measured, therefore, the time difference between two adjacent signals can be determined, which is defined as pre-determined time. When hair trap occurs, the rotation speed of the motor is slow down, the time difference between two adjacent signals become longer. The controller receiving the signals compares the time difference between two adjacent signals with the pre-determined time, if the time difference is greater than the pre-determined time, the controller classifies a hair trap problem occurs.

After a hair trap problem is classified to occur, the controller stops the motor, and triggers an alert signal to warn the user, and then the controller shuts down the hair curler. The user can restart the hair curler by pressing the switch 2 after removing the hair trap from the shell 100.

The foregoing embodiments merely are preferable embodiments of the present invention, and are not intended to define the scope claimed by the present invention, and any non-essential variations and substitutions made by those skilled in the art on the basis of the present invention fall within the scope claimed by the present invention.
