[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] In order to better describe and illustrate the embodiments of the present application, reference may be made to one or more drawings, but the additional details or examples used to describe the drawings should not be considered as limiting the scope of the utility model creation of the present application, any of the currently described embodiments or preferred methods.

[0030] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" are based on the positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention. They do not indicate that the device referred to must have a specific direction or operate in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0032] Electric shavers currently on the market often use switches in the form of inductive touch or mechanical touch to control the on and off of the circuit and thus control the start and stop of the motor. However, using only inductive touch or mechanical touch often causes the shaver to be started due to accidental touch by the user, resulting in power loss and other safety hazards.

[0033] In view of this, the utility model provides a touch-controlled shaver. Figure 1-5 For an embodiment of the touch-controlled shaver provided by the present invention, please refer to Figure 1-5 The touch-controlled shaver 1000 includes a main body 100, a cutter head assembly 200, and a protective cover 300 for protecting the cutter head assembly 200. The cutter head assembly 200 is detachably mounted on the main body 100 to facilitate cleaning of shaved hair.

[0034] Specifically, the main body 100 includes a housing 1, and a driving component 2 and a circuit board 3 arranged in the housing 1. The driving component 2 drives the connection to the cutter head component 200, and the circuit board 3 is used to control the opening and closing of the driving component 2. In addition, the touch-controlled shaver also includes a first touch component 400 and a second touch component 500 electrically connected to the circuit board 3. The first touch component 400 and the second touch component 500 can adopt touch modes such as inductive or mechanical. In specific use, when the human body touches the main body 100 for the first time, the first touch component 400 can wake up the conductive function of the circuit board 3. When the human body touches the cutter head component 200 again, the second touch component 500 can electrically connect the circuit board 3 to the power supply 4. The circuit board 3 is electrically connected and controls the driving component 2 to start, thereby driving the cutter head component 200 to work and realize the function of shaving hair. It should be noted that, in this embodiment, the first touch component 400 is of inductive type, which includes infrared sensing and pressure sensing to wake up the conductive function of the circuit board 3. Similarly, the second touch component 500 is a human body-powered method, through the power supply 4 to the blade assembly 200, and after contacting the human body, it flows back to the circuit board 3 in the housing 1 to complete the circuit control. Of course, in other embodiments, the second touch component 500 can also use a mechanical switch to power the circuit board 3, thereby performing circuit control.

[0035] In the technical solution of the utility model, when the user picks up the shaver with his hand, the conductive function of the circuit board 3 is awakened by the first touch part 400, and when the blade of the shaver is brought into contact with human skin, the second touch part 500 realizes the power supply of the circuit board 3, and the circuit board 3 controls the drive assembly 2 to drive the blade assembly 200 to work, thereby starting to shave the hair at the place where the skin is contacted. When the shaver leaves the human skin, the circuit board 3 is powered off, and the drive assembly 2 stops working. The above design requires two steps to start the shaver, effectively preventing the shaver from being started due to accidental touch, thereby preventing power loss and other safety hazards.

[0036] To prevent accidental touches due to collision, refer to Figure 4 In one embodiment of the utility model, the first touch component 400 includes an infrared sensor installed on the circuit board 3. When a human touches the main body 100 (that is, the housing 1) with a hand, the infrared rays emitted by the human hand are received by the infrared sensor on the circuit board 3, and then an electrical signal is generated and output. The signal processing circuit on the circuit board 3 amplifies and processes the weak electrical signal output by the infrared sensor, thereby awakening the conductive function of the circuit board 3. It should be understood that the first touch component 400 is not set to a mechanical touch mode, but an inductive mode, which can effectively prevent the circuit board 3 from being energized due to collision.

[0037] Further, after waking up the conductive function of the circuit board 3, in order to control the operation of the cutter head, please refer to Figures 2 to 5 In one embodiment of the utility model, the second touch part 500 is a bidirectional conductive spring pin, which can be installed on the main body 100 or on the cutter head assembly 200. In this embodiment, it is installed on the main body 100. The main body 100 also includes a power supply 4 installed in the housing 1, one end of the conductive spring pin is electrically connected to the power supply 4, and the other end is electrically connected to the cutter head assembly 200. After the conductive function of the circuit board 3 is awakened, the human hand and the part to be shaved touch the housing 1 of the main body 100 and the cutter head assembly 200 respectively, and the current of the power supply 4 passes through the conductive spring pin, the cutter head assembly 200, the human body and the housing 1 of the main body 100 in turn. The housing 1 of the main body 100 is electrically connected to the circuit board 3 and energizes the circuit board 3. At the same time, the circuit board 3 controls the drive assembly 2 to start, thereby driving the cutter head assembly 200 to shave hair; when the human hand and / or the part to be shaved stop contacting, the circuit board 3 is powered off, and the cutter head assembly 200 stops shaving hair. Of course, the implementation of the utility model is not limited to this. In other embodiments, when the human body touches the cutter head assembly, the cutter net of the cutter head assembly floats and contacts the end of the conductive spring pin, and the circuit is closed; when the human body stops touching the main body 100, the cutter net of the cutter head assembly rebounds and disconnects the circuit. It should be noted that the conductive spring pin is a common product on the market, and its two ends are elastically arranged and have a movable stroke to fully contact its conductive end in application.

[0038] Furthermore, to achieve the conduction of current between the conductive spring pin and the cutter head assembly 200, please refer to Figures 2 to 5 In one embodiment of the utility model, the cutter head assembly 200 includes an outer cover and a mounting frame 201 disposed in the outer cover, a metal bracket 202 is fixedly connected to the mounting frame 201, and a metal knife net 203 is electrically connected to the metal bracket 202. Specifically, the other end of the conductive spring pin contacts and is electrically connected to the metal bracket 202, so that when the hair part to be shaved of the human body touches the knife net 203, the power supply 4 transmits the current to the metal bracket 202 through the conductive spring pin, and then the metal bracket 202 transmits the current to the knife net 203, and then passes through the human body, and is transmitted from the shell 1 contacted by the human body to the circuit board 3 in the shell 1. When the human body leaves the knife net 203 and / or the shell 1, the power supply 4 and the circuit board 3 are disconnected.

[0039] To achieve electrical connection between the metal support 202 and the metal knife net 203, please refer to Figures 2 to 5 In one embodiment of the utility model, a plurality of metal springs 202a are provided on the metal support 202, and each metal spring 202a is connected to the outer periphery of the metal knife net 203 to realize the electrical connection between the metal support 202 and the metal knife net 203. In addition, the metal spring 202a can also make the metal knife net 203 have an up and down floating effect, so as to cut the hair shorter. The metal support 202 also has an electric contact for connecting with the conductive spring needle.

[0040] To achieve shaving of hair with the cutter head assembly 200, refer to Figure 2 In one embodiment of the utility model, a circular knife 204 cooperating with the metal knife net 203 is rotatably arranged in the metal knife net 203 to cut the hair extending into the metal knife net 203. In addition, in this embodiment, since the cutter head assembly 200 is detachably mounted on the main body 100 along the axial direction of the circular knife 204, in order to make the conductive end of the conductive spring pin and the metal bracket 202, the conductive spring pin is arranged along the axial direction of the circular knife 204, and then the metal bracket 202 can fully contact with the conductive spring pin.

[0041] To realize that the housing 1 of the main body 100 is electrically connected to the circuit board 3, please refer to Figure 3 and Figure 4 In one embodiment of the utility model, the shell 1 is a metal conductor, and the metal shell 1 is electrically connected to the circuit board 3 through a wire. When the human hand and the part to be shaved touch the metal shell 1 and the metal knife net 203 respectively, the power supply 4 is electrically connected to the circuit board 3.

[0042] Further, in one embodiment of the present invention, please refer to Figure 5 One end of the conductive spring pin is electrically connected to one pole of the power source 4, and the other pole of the power source 4 is electrically connected to the circuit board 3 to form a closed circuit.

[0043] To increase the sensitivity of the first touch panel 400, refer to Figure 4 In one embodiment of the present invention, the first touch panel 400 is disposed close to the metal housing 1 so that the photoelectric unit of its infrared sensor can better receive infrared rays emitted by the human body.

[0044] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
