[0029] 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.

[0030] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0031] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0032] In the prior art, electric shavers are generally provided with a push-type switch button for starting or shutting down the product, and the switch button is arranged on the body; users generally start or shut down the product by pressing the switch by hand, and the switch is prone to mechanical fatigue after long-term use, which leads to switch failure and reduces the service life of the product; in addition, when the user washes the product after use, external water can easily enter the body through the gap between the switch button and the body, which can easily cause short circuit and damage to the electronic components inside the body; another alternative is to design the switch button to be waterproof, which will result in numerous parts and complicated production.

[0033] Based on the above reasons, a touch-sensitive shaver is designed, comprising a shaver head 100 , a driving motor 200 , a touch sensor 300 and a controller 400 .

[0034] The driving motor 200 is connected to the razor head 100 and is used to drive the razor head 100 to rotate. The touch sensor 300 is used to send a touch signal according to the touch situation; the controller 400 is connected to the touch sensor 300 and the driving motor 200 respectively, and the controller 400 controls the driving motor 200 to turn on or off according to the electrical signal sent by the touch sensor 300.

[0035] It should be noted that the razor head 100 here is generally used for shaving beards, but it can also be used to remove hair from other parts. As long as it is for hair removal, it should fall within the scope of protection of this application. The drive motor 200 here can be one or more, and the razor head 100 is matched with the drive motor 200, and the drive motor 200 drives the razor head 100 to rotate, thereby removing hair. The signal emitted by the touch sensor here can be a resistance signal, a temperature signal, a pressure signal, or other signals that can be caused by touch rather than pressing. As long as the signal can be transmitted by touch, it should fall within the scope of protection of this application. The resistance signal here is generated by the resistance of the human body, the temperature signal is turned on according to the temperature range of the human body, and the pressure signal can be realized according to the pressure of the human hand on the touch sensor 300. These schemes can all generate a signal, which is then recognized by the controller 400 of this application and controls the opening or closing of the drive motor 200. The controller 400 is generally a circuit board, which controls the opening or closing of the driving motor 200 according to the electrical signal sent by the touch sensor 300, so that the shaver can be well controlled. The touch sensor 300 is generally a touch switch.

[0036] It should also be noted that the present application also includes components such as batteries and charging components that allow the shaver to operate normally. These features are not the focus of the present application and are also features frequently used in conventional shavers, so the present application will not elaborate on them here.

[0037] Further, the principle of the touch sensor 300, i.e., the touch switch, in the present application is explained: the touch switch is realized by the fluctuation of capacitance or resistance generated by touching the switch by a part of the human body, so that the touch switch transmits instructions to the controller 400, and the controller 400 controls the drive motor 200 to realize the purpose of turning on or off the drive motor 200. No pressing is required in the process of turning on and off the drive motor 200.

[0038] The touch key of a general touch switch adopts capacitive sensing technology. The human body is conductive, and the circuit under the capacitive sensing key can generate a uniformly distributed electrostatic field. When our finger moves over the key, the capacitance on the key surface changes. The relevant circuit makes a judgment based on the change in capacitance to achieve the predetermined function. Capacitive keys are very convenient to use. You only need to touch them without pressing hard to operate and realize the control of the drive motor 200.

[0039] When using the device of the present application, it is only necessary to make the skin (usually a finger) contact the touch sensor 300. At this time, the touch sensor 300 will release a touch signal due to the capacitance or resistance fluctuating due to being touched. The touch signal is received by the controller 400 and then controls the drive motor 200 to start. The start of the drive motor 200 can drive the razor head 100 to rotate for shaving or haircutting. When the device needs to be turned off, it is only necessary to make the skin (usually a finger) separate from the touch sensor 300. At this time, the capacitance or resistance of the touch sensor 300 fluctuates again due to the disappearance of the touch, and the touch signal is released again. The touch signal is received by the controller 400 and then controls the drive motor 200 to stop, and then the razor head 100 stops rotating. This process does not require the product to be started or turned off by pressing the switch by hand, and the switch will not fail due to mechanical fatigue caused by long-term use, thereby improving the service life of the razor.

[0040] In this embodiment, according to Figure 1 and Figure 2 As shown, the touch-sensitive shaver further comprises a housing 500, wherein the housing 500 has an installation space 510, and the drive motor 200 and the controller 400 are disposed in the installation space 510;

[0041] The housing 500 further includes an opening 530 , and the opening 530 is in communication with the installation space 510 ;

[0042] The touch sensor 300 includes a conductive part 310, one end of which is fixed to the controller 400 and electrically connected to the controller 400, and the other end of which is exposed through the opening 530. In the above configuration, the conductive part 310 is exposed to the outside, which makes it easier to touch, thereby facilitating the user to perform switch operations.

[0043] Furthermore, a motor bracket is provided inside the installation space 510, and a driving motor 200 is provided on each side of the motor bracket, and the motor bracket is fixedly connected to the support frame; a transmission shaft is provided on the other two sides of the motor bracket; a rotating shaft is provided at one end of the transmission shaft; a gear is provided at the other end of the transmission shaft, and the gear is transmission-connected to the output shaft of the driving motor 200. The above features are briefly described to ensure the integrity of the patent.

[0044] according to Figure 1 and Figure 2 As shown, the installation space 510 can be adapted to match the number of drive motors 200 of the present application. In the schematic diagram of the present application, it can be seen that a drive motor 200 is arranged on each side of the channel 520, and the matching razor head 100 is arranged in coordination with the two drive motors 200. Figure 2 It can also be seen that the battery is arranged at the lower side of the channel 520, and the sensor 300 is arranged at the side. When the internal components are determined in advance, the size and spatial layout of the installation space 510 are determined.

[0045] It can be understood that the opening 530 provided on the shell 500 is connected to the installation space 510. The purpose of the opening is to expose the conductive part to the outside world so that the user's finger can touch it, thereby causing the resistance value of the conductive part to change, and the conductive part 310 can be electrically connected to the controller 400, thereby transmitting electrical signals for control.

[0046] In this embodiment, according to Figure 1 and Figure 2 As shown, the housing 500 is provided with a channel 520 penetrating along the thickness direction, and an opening 530 is formed at each end of the channel 520 . There are multiple conductive parts 310 , and each opening 530 is provided with at least one conductive part 310 .

[0047] First, the channel 520 is arranged along the thickness direction so that the opening 530 can be arranged on the wall of the channel 520, and the conductive part is arranged on the wall, so that the user does not need to distinguish the front and back sides, and can contact the guide part regardless of the holding method.

[0048] It should also be noted here that the channel 520 can also be replaced by a receiving groove, so that the conductive part 310 is only set on one side. It should be noted that whether it is the channel 520 or the receiving groove, as long as a hole is set on the shell 500 and the conductive part 310 is set at the hole, it should be within the protection scope of the present application.

[0049] Further, according to Figure 2 As shown, the conductive part 310 includes a connecting unit 311 and an exposed unit 312 , the exposed unit 312 is located in the opening 530 , one end of the connecting unit 311 is connected to the exposed unit 312 , and the other end extends toward the inside of the shell 500 and is electrically connected to the controller 400 .

[0050] It should be noted that the connection unit 311 here includes a conductive pin and a conductive sheet; the conductive sheet is electrically connected to the circuit board and the battery through a conductor, and the circuit board and the battery circuit board assembly are connected to the exposed unit 312 through the conductive pin. In this way, the conductive part 310 can be separated into the connection unit 311 and the exposed unit 312 for installation and removal respectively, avoiding the trouble of the conductive part 310 being too large as a whole during installation.

[0051] It should also be noted that the exposed unit 312 here can be adjusted in conjunction with the housing 500 and the installation space 510. Figure 1 and Figure 2 The conductive ring is configured as a conductive ring but is not limited to the conductive ring. It may also be a square or a long strip. As long as the opening 530 can be closed and exposed to the outside, it should be within the protection scope of the present application.

[0052] In this embodiment, according to Figure 2 As shown, the exposed units 312 of the conductive parts 310 located in different openings 530 have the same axial direction and are connected to each other.

[0053] The axial directions of the multiple exposed units 312 are the same and they are connected to each other, so that the connection unit 311 can connect the exposed unit 312 with the controller 400 as long as it contacts one of the exposed units 312. It should be noted that the connection unit 311 here includes a conductive needle and a conductive sheet, the conductive sheet is arranged on the controller 400, and the conductive needle connects the conductive sheet and the exposed unit 312.

[0054] Furthermore, the conductive portion 310 is in a ring-shaped structure, and one of the conductive portions 310 closes one of the openings 530 .

[0055] The conductive part 310 is arranged in a ring structure, which is convenient for production. Most conductive devices on the market are arranged in a ring shape, and the ring shape can be matched with the channel 520 to be arranged in a ring shape, so that when the conductive part 310 is arranged in the channel 520, the opening on the channel 520 can be closed to the greatest extent. In addition, the housing 500 can be arranged in a ring shape, and the razor head 100 is arranged to match it, so that the whole machine is ring-shaped and has a very delicate appearance.

[0056] In this embodiment, according to Figure 2 As shown, there are two conductive parts 310, and an intermediate ring component 540 is arranged between the two conductive parts 310. A sealing groove is arranged at the place where the intermediate ring component 540 cooperates with the two conductive parts 310. A sealing ring 550 is arranged in the sealing groove. The sealing ring 550 is used to prevent water from entering the installation space 510.

[0057] Here, an intermediate ring component 540 is provided and two conductive parts 310 are provided, so that the two conductive parts 310 can be provided separately, and the connecting unit 311 can be provided independently for each, so that the device can still be used even if one conductive part 310 is damaged. At the same time, a sealing groove is provided in the intermediate ring component 540, and a sealing ring 550 is provided in the sealing groove to well prevent liquid from entering the installation space 510, thereby well protecting the internal components.

[0058] according to Figure 2As shown, in this embodiment, two conductive parts 310 are provided, and the conductive part 310 is a conductive ring, wherein the intermediate ring part 540 is correspondingly provided with two sealing grooves, and two sealing rings 550 are provided in the sealing grooves, and the sealing rings 550 are arranged between the intermediate ring part 540 and the conductive part 310, which can achieve a good waterproof effect, and such a design can also be easily installed, and it is only necessary to put the sealing ring 550 into the sealing groove, and then insert the conductive part 310 into the intermediate ring part 540, so that a good waterproof effect can be achieved.

[0059] The above description is about the waterproofing of the intermediate ring component 540 in cooperation with the sealing ring 550. Meanwhile, the conductive part 310 can be set as a conductive ring, and its end away from the intermediate ring component 540 can match the diameter setting of the channel 520, which can also achieve a good waterproofing effect.

[0060] In this embodiment, according to Figure 2 The housing 500 includes an outer shell 560 and an inner shell 570. The outer shell 560 has a receiving space 580, and the inner shell 570 is received in the receiving space 580. The installation space mentioned above is actually the space surrounded by the inner shell 570.

[0061] Along the axial direction of the channel 520 , there is a gap between the outer shell 560 and the inner shell 570 , and the conductive portion 310 covers the gap.

[0062] The outer shell 560 has a top opening, and the inner shell 570 can be placed in the outer shell 560. Since the outer shell 560 is sleeved on the outside of the inner shell 570, it can further prevent or reduce the external water from entering the installation space 510 of the inner shell 570, thereby protecting the electronic devices in the installation space 510.

[0063] Furthermore, the conductive part 310 covers the gap between the outer shell 560 and the inner shell 570 , so that the conductive part 310 can prevent liquid from entering the installation space 510 of the inner shell 570 through the gap, thereby achieving the purpose of protecting the electronic devices in the installation space 510 .

[0064] In this way, with the cooperation of the conductive part 310 , the outer shell 560 and the inner shell 570 , double protection is provided for the electronic components in the installation space 510 .

[0065] In this embodiment, the inner shell 570 includes a first inner shell 571 and a second inner shell 572 that are detachably connected, and the first inner shell 571 body 500 and the second inner shell 572 body 500 cooperate to form the installation space 510. The drive motor 200 and the controller 400 are disposed in the installation space 510. Of course, in other embodiments, the inner shell 570 may also be an integrally formed structure, or the first inner shell and the second inner shell may be fixedly connected and cannot be separated.

[0066] In the actual assembly process, the internal components (such as the drive motor 200, the controller 400, etc.) can be placed on one or both of the first inner shell 571 and the second inner shell 572. After that, the first inner shell 571 or the second inner shell 572 is covered again, and the whole formed by the first inner shell 571, the second inner shell 572 and the internal components is inserted into the receiving space 580 of the outer shell 561 through the top opening of the outer shell 560, and the whole formed by the first inner shell 571, the second inner shell 572 and the internal components is fixedly connected to the outer shell 560, and finally the conductive part 310 is installed in the channel 520. It can be understood that the first inner shell 571 and the second inner shell 572 are set to be detachably connected to facilitate subsequent disassembly and maintenance.

[0067] It should also be noted here that the outer rings of the first inner shell 571 and the second inner shell 572 can be provided with waterproof rings that match their outer rings, so as to prevent water from entering the installation space 510 from the outer rings to prevent damage to the electronic components in the installation space 510.

[0068] This patent includes multiple design points. One is to use a touch sensor 300 to replace the mechanical button, thereby avoiding the situation where the mechanical button is prone to mechanical fatigue after long-term use, which leads to switch failure, thereby increasing the service life of the shaver. And the solution of the touch sensor 300 does not bring other negative effects. Another is that the outer shell 560 and the inner shell 570 are set at the same time as the touch sensor 300, and the inner shell 570 includes a first inner shell 571 and a second inner shell 572 that can be detachably connected. This is convenient for installation on the one hand, and the outer shell 560 and the inner shell 570 can achieve a waterproof effect on the other hand. In addition, the present application also includes an intermediate ring component 540, and a sealing groove is provided at the intermediate ring component 540 and the two conductive parts 310. A sealing ring 550 is provided in the sealing groove, and the sealing ring 550 is used to prevent water from entering the installation space 510. The above sealing ring 550 cooperates with the outer shell 560 and the inner shell 570 to achieve a double waterproof effect, and achieves a good protection effect for the components in the installation space 510.

[0069] It should also be noted that the housing 500 is provided with a channel 520, which is convenient for taking, and a conductive part 310 is provided in the channel 520, so that the device can be started when the device is picked up. Figure 1-3 As shown, the housing 500 and the channel 520 can be set to be circular, so that the entire device becomes a ring shape, which is not only convenient to take but also more beautiful.

[0070] The above description is only an optional embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made based on the concept of the present application and the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are included in the patent protection scope of the present application.
