Description

Technical Field

[0001] This application relates to the field of nursing equipment technology, and in particular to a sensor-activated shaving head and shaving device. Background Technology

[0002] Electric shavers are grooming appliances that use electricity to drive the blades and trim beards and sideburns. A traditional electric shaver consists of a stainless steel mesh cover, a blade head, a miniature electric motor, and a housing. The mesh cover has many holes through which beard hairs can be inserted. The miniature electric motor, powered by electricity, drives the blade head to cut the hairs inserted into the holes using a shearing principle. Electric shavers are small, portable, and can be used anytime, making them a top choice for men traveling with.

[0003] Currently available smart rotary electric shavers use skin-sensing technology, utilizing microcurrents on the skin's surface to activate and shut down the device. This technology relies on micro-charge sensors within the shaver; when the sensor contacts the skin, it sensitively detects the current, instantly and automatically turning it on. However, the biggest drawback of this technology is its inability to effectively prevent accidental activation. The shaver will automatically start when the hand or other parts of the body touch the shaver head, or when the shaver head needs to be cleaned with water. This not only results in unnecessary power consumption but also poses a certain safety risk. Utility Model Content

[0004] Based on this, the purpose of this application is to provide a sensor-activated shaving head and a shaving device including the sensor-activated shaving head, so as to solve the problem that when people use existing shaving devices, they cannot avoid accidentally touching the shaving head, which causes the automatic triggering switch to make the shaving device work, resulting in meaningless power consumption and even certain safety risks.

[0005] According to one aspect of this application, a sensor-activated shaving head is provided, comprising:

[0006] A housing, wherein a middle frame is provided inside the housing, and a first conductive element is provided on the middle frame;

[0007] A cutting head assembly includes a cutting head and a transmission module, wherein the transmission module is tractively connected to the cutting head and electrically connected to the first conductive element, and the transmission module is used to drive the cutting head to rotate about its own central axis when electrically connected to the first conductive element;

[0008] A blade mesh assembly is elastically connected to the housing and covers the blade head. The blade mesh assembly can move relative to the housing from the outside of the housing to the inside of the housing under the action of external force.

[0009] A conductive component is elastically connected to the middle frame. The conductive component can be abutted by the blade mesh assembly and move relative to the middle frame when the blade mesh assembly moves from outside the housing to inside the housing, so that the end of the conductive component away from the blade mesh assembly can abut against the first conductive element, thereby making the first conductive element electrically connected to the transmission module.

[0010] In one embodiment, the conducting component includes:

[0011] A press-fit component is connected to the middle frame, and the press-fit component is capable of undergoing recoverable deformation under the action of the external force;

[0012] A conductive spring includes a connecting portion and a first contact portion and a second contact portion connected to the connecting portion. The connecting portion is movably disposed on the middle frame. The first contact portion is used to be abutted by the pressing member when the pressing member undergoes a recoverable deformation, so as to simultaneously drive the second contact portion to abut against the first conductive element.

[0013] A first elastic element is disposed on the middle frame and connected to the first contact portion. The first elastic element is configured to generate elastic deformation when the press member abuts against the first contact portion, so as to provide an elastic force to reset the first contact portion and the second contact portion.

[0014] In one embodiment, the connecting portion includes a first sub-connecting portion and a second sub-connecting portion that are connected to each other. One end of the first sub-connecting portion is connected to the first contact portion, and one end of the second sub-connecting portion is connected to the second contact portion. The first sub-connecting portion and the second sub-connecting portion are arranged at an angle such that the end of the first sub-connecting portion away from the first contact portion and the end of the second sub-connecting portion away from the second contact portion form a protrusion that contacts the middle frame.

[0015] In one embodiment, the blade assembly includes a blade support, the blade head is at least partially disposed within the blade support, the blade support is inclined relative to the outside of the housing and rotatably connected to the housing, so that the blade assembly can rotate relative to the housing by an angle under the action of an external force and then abut against the conductive component.

[0016] In one embodiment, the blade mesh assembly further includes a blade mesh covering and connected to the blade head, the blade mesh being movably inserted into the blade mesh assembly and at least partially protruding from the outer surface of the blade mesh support, the blade mesh being movable relative to the blade mesh support from outside the housing towards inside the housing under the action of an external force; the blade mesh is also connected to the blade mesh support via a blade mesh spring sheet disposed in the housing, the blade mesh spring sheet being used to generate an elastic force that resets the blade mesh when it moves relative to the blade mesh support.

[0017] In one embodiment, the blade holder has a limiting groove in the portion located inside the housing, and a positioning block is provided in the limiting groove. The blade and the blade spring are both connected to the positioning block. When the blade moves relative to the blade holder, the positioning block can move within the limiting groove. The two opposite groove walls of the limiting groove are used to abut against the positioning block to limit the movement distance of the positioning block and to cause the blade spring to undergo recoverable deformation.

[0018] In one embodiment, the housing is provided with a blade positioning frame detachably connected to the housing. The blade positioning frame includes a sleeve and a connecting ring connected to the sleeve, and the blade spring clip is engaged with the connecting ring.

[0019] In one embodiment, the inner wall of the housing is provided with a plurality of buckles spaced apart along a circumferential direction. All the buckles pass through the sleeve and engage with the end face of the sleeve to restrict the sleeve from moving along its own axial direction.

[0020] In one embodiment, one of the inner wall of the housing and one end of the sleeve is provided with a groove, and the other is provided with a boss. The boss is engaged in the groove to restrict the sleeve from rotating in its circumferential direction.

[0021] And / or, the outer side wall of the sleeve is provided with a first limiting block, and the inner wall of the housing is provided with a second limiting block. The first limiting block and the second limiting block are used to abut against each other to limit the rotation angle of the sleeve along the circumferential direction.

[0022] According to another aspect of this application, a shaving device is provided, comprising:

[0023] As described in any of the above solutions, a sensor-activated shaving head;

[0024] The drive unit includes a drive source and a connection terminal electrically connected to the drive source. The drive source is detachably connected to the transmission module of the sensing shaving head, and the connection terminal is detachably electrically connected to a first conductive element of the sensing shaving head.

[0025] The aforementioned inductive shaving head and shaving device, by providing a first conductive element electrically connected to a drive source on the middle frame of the housing, and a blade assembly elastically connected to the middle frame, and the blade assembly elastically connected to the housing, allows the blade assembly to move from the outside of the housing towards the inside of the housing and abut against the conductive component when subjected to external force (such as the contact force of skin). This causes the conductive component to move relative to the middle frame of the housing, allowing the end of the conductive component away from the blade assembly to abut against the first conductive element, thereby making the first conductive element electrically connected to the drive source. Since the drive source is connected to the transmission module, it can drive the transmission module to rotate the shaving head and begin the shaving operation. Therefore, when the blade assembly contacts the skin, the conductive component does not immediately contact the first conductive element. This allows the shaving device provided by this application to not only have inductive conductivity but also avoid accidental triggering of the switch, thus saving power and preventing safety accidents.

[0039] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0040] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0041] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0042] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0044] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0045] See Figure 1 and Figure 2 , Figure 1 A schematic diagram of an induction shaving head 100 according to an embodiment of this application is shown. Figure 2 A cross-sectional view of the induction shaving head 100 provided in this embodiment is shown. The induction shaving head 100 provided in one embodiment of this application includes a housing 110, a shaving head assembly 120, a foil assembly 130, and a conductive assembly 140. The housing 110 has a middle frame 111, which divides the cavity enclosed by the housing 110 into an upper cavity and a lower cavity. A first conductive element 150 is provided on the middle frame 111. The conductive assembly 140 is disposed on the middle frame 111. Multiple shaving head assemblies 120 are provided, each shaving head assembly 120 being disposed within the housing 110 and including a shaving head 121 and a transmission module 122. The transmission module 122 of each shaving head assembly 120 is drively connected to the corresponding shaving head 121 and electrically connected to the first conductive element 140. Electrical component 150; multiple blade mesh assemblies 130 are also correspondingly provided. Each blade mesh assembly 130 is connected to the housing 110 and covers the blade head 121 of a corresponding blade head assembly 120. The blade mesh assembly 130 is used to contact the skin and apply a certain pressure to the skin, so that under the action of the skin, the blade mesh assembly 130 can be electrically connected to the first conductive element 150 through the conductive component 140, thereby making the transmission module 122 electrically connected to the first conductive element 150, and driving the blade head 121 to rotate around its own central axis when electrically connected to the first conductive element 150, so that the blade head 121 can cut the beard by using the shearing principle when rotating.

[0046] Thus, when the blade assembly 130 comes into contact with the skin and a certain contact force is applied, the blade assembly 130 is electrically connected to the first conductive element 150 through the conductive component 140, which can cause the blade head 121 to rotate, thereby achieving inductive conduction and making it convenient for the user.

[0047] However, as described in the background section, the biggest drawback of the inductive conduction technology in the prior art is that it cannot effectively prevent accidental touches. When the hand or other parts of the body come into contact with the foil assembly 130, or when the part inside the foil assembly 130 needs to be cleaned with water, the switch will be automatically triggered to make the shaving device 10 work. This not only causes meaningless power consumption, but also poses a certain risk of safety accidents.

[0048] Therefore, in order to solve this problem, in one embodiment, the blade mesh assembly 130 is elastically connected to the housing 110. Under the action of external force, such as when the skin comes into contact with the blade head 121, the blade mesh assembly 130 can move from the outside of the housing 110 toward the inside of the housing 110 relative to the housing 110 under the contact force of the skin. The conductive assembly 140 is elastically disposed on the middle frame 111 and can move relative to the middle frame 111.

[0049] Specifically, such as Figure 3 As shown, the blade mesh assembly 130 includes a blade mesh bracket 132, which is inclined relative to the outer side of the housing 110 and rotatably connected to the housing 110. The blade mesh bracket 132 is also elastically connected to the housing 110 via a second elastic element 133, such as a spring, so that the blade mesh assembly 130 can rotate relative to the housing 110 by an angle under the action of an external force. At the same time, the second elastic element 133 can be stretched when the rotation of the blade mesh assembly 130 is limited and stopped by the housing 110, thereby providing an elastic force to reset the blade mesh assembly 130.

[0050] In the initial state, combined Figure 2 and Figure 3 As shown, the conductive component 140 does not contact the first conductive element 150. When the entire blade assembly 130 rotates relative to the housing 110, the blade bracket 132 can contact the conductive component 140. Since the conductive component 140 can move relative to the middle frame 111, when the blade assembly 130 moves from the outside of the housing 110 to the inside of the housing 110, the conductive component 140 can be abutted by the blade assembly 130 and move relative to the middle frame 111, so that the end of the conductive component 140 away from the blade assembly 130 can abut against the first conductive element 150, thereby making the first conductive element 150 electrically connected to the transmission module 122.

[0051] Thus, it can be seen that when the foil assembly 130 contacts the skin and applies a certain pressure, the foil assembly 130 will rotate a certain angle before contacting the conductive assembly 140. The conductive assembly 140 itself will move relative to the middle frame 111 before contacting the first conductive element 150. Therefore, there is a certain time difference between the foil assembly 130 contacting the skin and the conductive assembly 140 contacting the first conductive element 150, so that the conductive assembly 140 will not immediately contact the first conductive element 150. This allows the shaving device 10 provided in this application to not only have the function of inductive conductivity, but also to avoid accidental triggering of the switch to make the shaving device 10 work, thereby saving power and avoiding the occurrence of safety accidents.

[0052] Furthermore, based on the above embodiments, the foil assembly 130 also includes a foil 131 that covers and is connected to the blade head 121. The foil 131 has multiple holes that penetrate its inner and outer sides. When shaving, the beard extends into the foil 131 through the holes. As the blade head 121 rotates, the blade head 121 can cut the beard that has extended into the foil 131, thereby protecting the skin and making the shaving smoother.

[0053] Preferably, such as Figure 4 As shown, the blade mesh 131 is movably inserted into the blade mesh support 132 and protrudes from the outer surface of the blade mesh support 132. When the blade mesh 131 comes into contact with the skin, the skin contacts the blade mesh 131 first. Under the contact force of the skin, the blade mesh 131 and the blade head 121 can move a certain distance from the outside of the housing 110 towards the inside of the housing 110, where they are stopped by the blade mesh support 132 and cannot move further. Then, the blade mesh assembly 130 rotates relative to the housing 110 at an angle. Simultaneously, a blade mesh positioning bracket 160 is detachably provided inside the housing 110. A blade mesh spring piece 170 connected to the blade mesh 131 is engaged on the blade mesh positioning bracket 160. The blade mesh spring piece 170 has a certain elasticity and is configured to generate an elastic force that allows the blade mesh 131 to return to its original position when it moves relative to the blade mesh support 132. When the blade net 131 comes into contact with the skin, the blade net 131 and the blade head 121 can move together in the direction from the outside of the housing 110 to the inside of the housing 110. When the blade net 131 is separated from the skin, the blade net 131 and the blade head 121 can be reset together under the elastic force provided by the blade net spring 170.

[0054] Thus, through the above-described configuration, the blade 131 and the skin are in flexible contact. The blade 131 can move relative to the blade holder 132, and the blade holder 132 can rotate relative to the housing 110. Compared to the traditional implementation where the blade holder 132 cannot move and the blade 131 can only move relative to the blade holder 132, or the blade holder 132 can only rotate relative to the housing 110, the blade 131 can better conform to the skin, allowing the blade head 121 to fully shave the beard or hair, avoiding incomplete shaving due to insufficient contact between the blade 131 and the skin, or the risk of scratching the skin.

[0055] In one optional embodiment, please continue to refer to Figure 2 The transmission module 122 has a gear meshing structure, including an input gear 1221 and an output gear 1222 meshing with the input gear 1221. The blade head 121 is connected to the output gear 1222. The input gear 1221 is connected to an input shaft 1223, and the output gear 1222 is connected to an output shaft 1224. A connecting shaft spring 1225 is provided between the input shaft 1223 and the input gear 1221, and a connecting shaft spring 1225 is also provided between the output shaft 1224 and the output gear 1222. This ensures that when the blade mesh 131 comes into contact with the skin, the blade mesh assembly 130 abuts against the output shaft 1224. In addition to the elastic force generated by the second elastic element 133 and the blade mesh spring 170, the connecting shaft spring 1225 also generates a recoverable elastic deformation, thus further increasing the flexibility of the contact between the blade mesh 131 and the skin. Of course, the transmission module 122 can also be other types of transmission structures, and there is no particular limitation here.

[0056] As shown in the figure, regarding the connection method between the blade mesh 131 and the blade mesh spring 170, and the structure for limiting the blade mesh 131, in one optional embodiment, as follows: Figure 4 As shown, the blade mesh support 132 has a stop structure 1321 at one end near the inner end of the housing 110. The stop structure 1321 is bent from the edge of the end of the blade mesh support 132, so that the stop structure 1321 and the step in the blade mesh support 132 form a limiting groove 1322 in the part of the blade mesh support 132 located in the housing 110. A positioning block 180 is provided in the limiting groove 1322. The blade mesh 131 and the blade mesh spring piece 170 are both connected to the positioning block 180. When the blade mesh 131 moves relative to the blade mesh support 132, the positioning block 180 can move in the limiting groove 1322. The two opposite groove walls of the limiting groove 1322 are used to abut against the positioning block 180 to limit the movement distance of the positioning block 180 and to make the blade mesh spring piece 170 undergo recoverable deformation.

[0057] Furthermore, the blade holder 132 is provided with a positioning guide post 1323, and the positioning block 180 is provided with a through hole penetrating its opposite ends. The positioning guide post 1323 passes through the through hole, so that the positioning block 180 is sleeved on the positioning guide post 1323 and can only move along the axial direction of the positioning guide axis. Therefore, the positioning guide post 1323 can play a guiding role when the positioning block 180 moves, preventing the positioning block 180 from deviating from the predetermined trajectory when moving, so that the blade 131 will not shift when moving relative to the blade holder 132.

[0058] See Figure 5 In the structure of the conductive assembly 140, the conductive assembly 140 includes a crimping member 141, a conductive spring sheet 142 and a first elastic element 143. The crimping member 141 is connected to the middle frame 111, the conductive spring sheet 142 is disposed at one end of the crimping member 141 away from the blade assembly 130, and the first elastic element 143 is disposed on the middle frame 111 and connected to the conductive spring sheet 142. Specifically, the crimping member 141 is made of an elastic material, and under the action of external force, the crimping member 141 can undergo recoverable deformation; the conductive spring 142 includes a connecting portion 1421 and a first contact portion 1422 and a second contact portion 1423 connected to the connecting portion 1421. The connecting portion 1421 is movably disposed on the middle frame 111. The first connecting portion 1421 is used to be abutted by the crimping member 141 when the crimping member 141 undergoes recoverable deformation, so as to simultaneously drive the second contact portion 1423 to abut against the first conductive element 150; for example, the first elastic element 143 is a spring, one end of which is connected to the first contact portion 1422. When the crimping member 141 abuts against the first contact portion 1422, the first elastic element 143 can generate elastic deformation to provide an elastic force to reset the first contact portion 1422 and the second contact portion 1423.

[0059] In one embodiment, the middle frame 111 has mounting holes 111a extending through both sides, and the crimping member 141 is disposed at the mounting holes 111a. Specifically, the crimping member 141 includes a plastic part 1411 and a silicone part 1412 sleeved on the plastic part 1411 and connected to the middle frame 111. The silicone part 1412 seals the mounting holes 111a to provide waterproofing, and the silicone part 1412 is made of a relatively soft material, capable of undergoing recoverable deformation under the abutment force of the blade assembly 130. The plastic part 1411 is relatively hard and is covered by the silicone part 1412, which supports the silicone part 1412, thereby facilitating the blade assembly 130 to press the crimping member 141, so that the crimping member 141 can abut against the conductive spring 142 with sufficient abutment force.

[0060] In terms of the specific shape of the connecting portion 1421 of the conductive spring 142, the connecting portion 1421 includes a first sub-connecting portion 1421a and a second sub-connecting portion 1421b that are connected to each other. One end of the first sub-connecting portion 1421a is connected to the first contact portion 1422, and one end of the second sub-connecting portion 1421b is connected to the second contact portion 1423. The first sub-connecting portion 1421a and the second sub-connecting portion 1421b are set at an angle, so that the connecting portion 1421 is approximately "V" shaped. Thus, the end of the first sub-connecting portion 1421a away from the first contact portion 1422 and the end of the second sub-connecting portion 1421b away from the second contact portion 1423 form a protrusion that contacts the middle frame 111.

[0061] It is easy to see that when the pressure head assembly abuts against the pressure member 141, and the pressure member 141 abuts against the first contact portion 1422 of the conductive spring 142, it is similar to using the lever principle to make the second contact portion 1423 tilt up, so that it can abut against the first conductive element 150 and make the first conductive element 150 electrically connected to the transmission module 122.

[0062] Here, as Figure 6 and Figure 7 As shown, the first conductive element 150 is a combination of a metal sheet 151 and a conductive spring 152. There are two metal sheets 151, which represent the positive and negative terminals respectively. As shown, one of the two metal sheets 151 is connected to one end of the conductive spring 152, and the other is connected to the other end of the conductive spring 152. Correspondingly, the second contact portion 1423 has two contacts, one of which is used to abut against one of the metal sheets 151, and the other is used to abut against the other metal sheet 151.

[0063] Therefore, it can be understood that the conductive spring 142 acts as a bridge here. When the two contacts of the second contact 1423 abut against the two metal plates 151 respectively, the positive and negative terminals of the first conductive element 150 are connected, thus forming a circuit, enabling the first conductive element 150 to be electrically connected to the transmission module 122.

[0064] See Figure 4 In the structure of the knife net positioning frame 160, the knife net positioning frame 160 includes a sleeve 161 and a connecting ring 162 connected to the sleeve 161. The knife net spring piece 170 is engaged with the connecting ring 162. The connecting ring 162 is positioned opposite the cutter head 121. It is used to abut against the cutter head 121 when the knife net 131 and the cutter head 121 move relative to the knife net support 132, thereby preventing the knife net 131 and the cutter head 121 from falling off.

[0065] In one implementation, combined Figure 4 and Figure 8As shown, the inner wall of the housing 110 is provided with a plurality of buckles 112 spaced apart along a circumferential direction. All buckles 112 pass through the sleeve 161 and are engaged with the end face of the sleeve 161, so that the opposite ends of the sleeve 161 cannot move along their own axial direction under the limitation of the buckles 112 and the inner wall of the housing 110.

[0066] Optionally, one end of the sleeve 161 is provided with several grooves 1611, and the inner wall of the housing 110 is provided with several protrusions 113. The protrusions 113 are engaged in the grooves 1611, thereby restricting the sleeve 161 from rotating in the circumferential direction of the arrangement of the multiple latches 112. Therefore, it can effectively prevent the shaving device from rotating due to the shaking of the foil positioning frame 160 during transportation or use. Of course, the protrusions 113 can also be provided at the end of the sleeve 161, and the grooves 1611 are provided on the inner wall of the housing 110.

[0067] Preferably, the depth of the groove 1611 and the height of the boss 113 are both relatively small. When it is necessary to replace or clean the cutter head 121 and disassemble the cutter head positioning frame 160, simply rotate the sleeve 161 around its own central axis. At this time, the boss 113 is engaged in another groove 1611. At this time, the connecting ring 162 is offset from the cutter head 121 (i.e., not directly facing the cutter head 121), and the cutter head 121 can be removed.

[0068] More preferably, the outer wall of the sleeve 161 is provided with a first limiting block 1612, and the inner wall of the housing 110 is provided with a second limiting block 114. The first limiting block 1612 and the second limiting block 114 are used to abut against each other to limit the rotation angle of the sleeve 161 along the aforementioned circumferential direction. In this way, when the sleeve 161 is rotated by a certain angle to make the connecting ring 162 deviate from the cutter head 121 before changing the cutter head 121, the sleeve 161 can be further prevented from continuing to rotate.

[0069] In addition, to facilitate the disassembly of the various components in the sensor shaver head 100, the housing 110 is designed as a detachable structure. Specifically, such as... Figure 2 As shown, the housing 110 includes an upper housing 115 and a lower housing 116. The inner wall of the upper housing 115 forms an upper cavity, and the inner wall of the lower housing 116 forms a lower cavity. A portion of the blade assembly 130 is located in the upper cavity, while at least a portion of the conductive element and at least a portion of the second conductive element 3212 are located in the lower cavity. The output shaft 1224 of the transmission module 122 passes through a partition, meaning that a portion of the transmission module 122 is located in the upper cavity to connect to the blade head 121, and another portion is located in the lower cavity to connect to the drive module 320. Magnets can be installed in the upper and lower cavities respectively, allowing the upper housing 115 and lower housing 116 to be magnetically connected to each other, thus facilitating the disassembly and cleaning of internal components while ensuring current conduction.

[0070] It should be noted that the number of foil components 130 in the sensor shaving head 100 is not limited; it can be one or any number. Obviously, setting multiple foil components 130 can result in a better shaving effect.

[0071] Furthermore, one embodiment of this application also provides a shaving device 10, see reference. Figure 9 and Figure 10 The shaving device 10 of this embodiment includes a body 200, a drive unit 300 and a sensor shaving head 100 as described in the above embodiment, wherein the sensor shaving head 100 is connected to the drive unit 300, and the drive unit 300 is disposed inside the body 200.

[0072] In one embodiment, see Figure 10 The drive unit 300 includes a control module 310 and a drive module 320. The control module 310 includes a battery 311 and a main control system 312 connected to the battery 311. The battery 311 is used to supply power to the main control system 312. The main control system 312 can be, for example, a PCB board, which is used to provide control signals to control the operation of the drive module 320. The drive module 320 includes a drive source 321 and a relay component 322. The drive source 321 is used to provide power or provide electrical signals. The relay component 322 is used to transmit the power and electrical signals provided by the drive source 321 to the induction shaver head 100, so that the induction shaver head 100 can realize the shaving function.

[0073] Specifically, see Figure 11 The relay component 322 is provided with a connection terminal 3221, and the drive source 321 is provided with an adapter sleeve 3211 and a second conductive element 3212 that is connected to the control module 310 for communication. One end of the connection terminal 3221 is connected to the first conductive element 150 in the induction shaving head 100, and the other end is connected to the second conductive element 3212, thereby realizing the electrical connection between the drive module 320 and the shaving head 121. One end of the adapter sleeve 3211 is connected to the drive source 321, and the other end is detachably connected to the input shaft 1223 of the transmission module 122, so that the control module 310 can control the drive module 320 to drive the transmission module 122 to drive the shaving head 121 to rotate.

[0074] Therefore, when using the shaving device 10 provided in this application, the user can effectively avoid the drawback of accidentally activating the shaving device 10 automatically by touching the blade 131 within a certain range, and can achieve true contact with the skin without dead angles, avoid scratching the skin, and make the shave more thorough.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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.

[0076] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
