TECHNICAL FIELD

[0003] The present application belongs to the technical field of electric shavers, and in particular relates to an electric shaver. BACKGROUND

[0004] Electric shavers can achieve high-speed vibration, have the advantages of fast shaving speed, large shaving area, more thorough cleaning, high cleaning efficiency, etc., and are widely loved by users. At present, the electric shaver has the following problems:

[0005] 1. The head, linear motor and battery of the electric shaver are arranged in a "one" shape in a longitudinal direction, the internal structure layout is complicated, and there is a large gap between the motor module and the charging assembly arranged at the bottom of the shell, so that the overall length of the shaver product is large, the volume is large, the space occupied is large, and it is not convenient for users to store and carry;

[0006] 2. The internal layout design of the electric shaver is relatively complex, and the component arrangement is not optimized, which directly leads to a significant reduction in the assembly efficiency of the power supply assembly;

[0007] 3. The charging module of the electric shaver is usually arranged at the bottom of the shell, and the circuit board of the charging module and the main circuit board of the device are usually connected by complete wires. However, the wires are usually fixed on the main control circuit board and the circuit board of the charging module by welding. When the device needs to be repaired or the circuit board needs to be replaced, the disassembly and installation of the wires are not convenient, which reduces the disassembly and assembly efficiency. Secondly, the welding connection mode fixes the connection between the modules, which limits the modular design of the device, making it difficult to realize the independent installation and replacement of each component. In addition, the wiring requirement of the wires and the operation space requirement in the welding process may limit the optimal use of the internal space of the device, which is not conducive to the miniaturization of the device;

[0008] 4. Since the electric shaver has many electronic devices, the electrical connection between some electronic devices needs to be ensured during the assembly of the electric shaver, so the assembly process is relatively complex.

[0060] Referring to FIGS. 1-8, the present application provides an electric shaver 100, which includes a housing 110, a motor 120, a mounting bracket 130, and two power supply units 140 mounted in the housing 110. The mounting bracket 130 is provided with a first accommodating cavity 131 and two second accommodating cavities 132 located on both sides of the first accommodating cavity 131, the motor 120 is arranged in the first accommodating cavity 131, and the two power supply units 140 are arranged in the two second accommodating cavities 132, respectively.

[0061] Specifically, the housing 110 provides installation and protection for the internal structure of the electric shaver 100, ensuring the safety and stability of the internal components. The shape of the housing 110 includes but is not limited to a cuboid, a cylinder, or is similar to a cuboid or a cylinder. The housing 110 can be made of ABS plastic, engineering plastic, etc., and can also be made of high-strength, wear-resistant metal materials such as aluminum alloy.

[0062] The output shaft 121 of the motor 120 is connected with a head assembly 200 of the electric shaver 100. Specifically, the output shaft 121 of the motor 120 is connected with a moving blade to drive the moving blade to move at a high speed relative to a stationary blade to achieve shearing. The structure of the head assembly 200 can be various, which includes at least one head, each head having a stationary blade and a moving blade, and the moving blade can move linearly and reciprocally relative to the stationary blade in a predetermined direction. The head can be a long hair head or a short hair head, which can be selected and designed according to the use requirement, and is not specifically limited here.

[0063] The mounting bracket 130 is a support structure for fixing the motor 120, the power supply units 140, and other components. The mounting bracket 130 can generally be made of insulating materials such as plastic to insulate the two power supply units 140.

[0064] The power supply unit 140 is the power source of the electric shaver 100, which provides power for the entire electric shaver. The power supply unit 140 includes but is not limited to a lithium-ion battery, a nickel-hydrogen battery, a nickel-cadmium battery, and a lithium polymer battery, and the type of battery can be selected and designed according to the actual requirement, and is not specifically limited here.

[0065] The electric shaver 100 of the present application is characterized in that the mounting bracket 130 is provided with a first accommodating cavity 131 and a second accommodating cavity 132 on both sides of the first accommodating cavity 131, the motor 120 is arranged in the first accommodating cavity 131, and the two power supply units 140 are arranged in the two second accommodating cavities 132, respectively. That is, the power supply is disassembled into two power supply units 140 arranged on the transverse two sides of the motor 120. Compared with the traditional shaver in which the motor 120 and the battery are arranged in a "one" shape in the longitudinal direction, the length of the shaver is minimized without increasing the thickness of the electric shaver, and the gravity distribution of the entire electric shaver 100 is uniform, so that the entire shaver structure is compact, small in size, small in space occupation, and more convenient for users to store and carry. In addition, the mounting bracket 130 can provide installation and protection for the two power supply units 140, avoid accidental damage of the power supply units 140, and make full use of the space between the two power supply units 140 to install the motor 120, so that the overall structure is more compact.

[0066] In some embodiments, the motor 120 is a linear motor, and the two power supply units 140 are arranged on the two sides in the reciprocating direction of the linear motor.

[0067] Specifically, the linear motor can be a magnetic levitation linear motor or other types of linear motor, as long as it can realize the linear translation motion of the output shaft 121. The electric shaver 100 adopts the linear motor, which is high in precision, fast in response speed, high in sensitivity, reliable in work, small in weight and volume, and conducive to the miniaturization of the electric shaver 100. The electric shaver 100 can use only one linear motor to drive the moving knife to move, or can use two linear motors, which is not limited here.

[0068] The linear motor drives the moving knife to move linearly along the preset direction to realize shearing relative to the static knife. For the convenience of description, the reciprocating direction of the linear motor is defined as the width direction of the electric shaver 100, the axial direction of the output shaft 121 is defined as the height direction of the electric shaver 100, and the thickness direction of the electric shaver 100 is the direction perpendicular to the width direction and the height direction of the electric shaver 100. It can be understood that, when the linear motor works, it needs to drive the output shaft 121 to reciprocate in the preset direction, so the two ends of the linear motor in the preset direction will have a slight vibration. By arranging the two power supply units 140 on the two sides in the reciprocating direction of the linear motor, the two power supply units 140 can balance and weaken the amplitude of the two ends in the reciprocating direction of the linear motor, weaken the vibration of the entire electric shaver 100, and improve the use effect of the product.

[0069] In some embodiments, referring to FIGS. 9 and 10, the electric shaver 100 further comprises a main control board 151 connected to the mounting bracket 130. Each second accommodating cavity 132 has a notch facing the inner side wall of the housing, and the main control board 151 covers the notch.

[0070] Specifically, the main control board 151 is an electronic component that controls and manages the operation of the electric shaver 100. The main control board 151 covers the notch of each second accommodating cavity 132 and is connected to the mounting bracket 130. At this time, the main control board 151 can prevent the power supply unit 140 from being detached from the notch of the second accommodating cavity 132, reducing the risk of displacement or damage of the power supply unit 140 due to vibration or impact.

[0071] In the related art, the main control board is usually arranged on one side of the mounting bracket, and the assembly groove is arranged on the other side of the mounting bracket. The power supply unit is embedded in the assembly groove and is fixed by means of adhesive tape or the like to prevent the power supply unit from being detached from the assembly groove. This arrangement increases the assembly difficulty and reduces the assembly efficiency. At the same time, the power supply unit and the main control board are far apart, resulting in an excessively long connecting cable between them, which occupies too much internal space, thereby increasing the volume of the electric shaver.

[0072] In the above embodiments, the main control board 151 covers the notch of each second accommodating cavity 132 and is connected to the mounting bracket 130. During assembly, the power supply unit 140, the mounting bracket 130, and the main control board 151 can be assembled into a whole, and then assembled into the housing 110. The structure is simple, and the assembly efficiency is high. Since the main control board 151 covers the notch of each second accommodating cavity 132, the power supply unit 140 can be prevented from being detached from the second accommodating cavity 132, reducing the number of components of the electric shaver 100. After assembly, the components are arranged compactly, which can effectively utilize the internal space of the housing 110, reduce the volume, and make the overall structure more compact.

[0073] In some embodiments, referring to FIGS. 11-15, the housing 110 is provided with a charging assembly 160 on the bottom wall 112 of the inner cavity, and the mounting bracket 130 is provided with a through hole 133 corresponding to the charging assembly 160 and communicating with the first accommodating cavity 131. The motor 120 includes a motor frame 122, a conductive adapter plate 123, two first conductive parts 124, at least two conductive wires 125, a driving component 126 and a moving component 127 mounted in the motor frame 122. The conductive adapter plate 123 is arranged at one end of the motor frame 122 facing the charging assembly 160. The two first conductive parts 124 are electrically connected with the conductive adapter plate 123 and are used to be electrically connected with the power supply unit 140. The two first conductive parts 124 are arranged on one side of the conductive adapter plate 123 facing the charging assembly 160 and are spaced apart to form a mounting space 128 between them for accommodating the charging assembly 160. The charging assembly 160 extends into the mounting space 128 through the through hole 133. One end of the conductive wire 125 is electrically connected with the driving component 126, and the other end is electrically connected to the conductive adapter plate 123 at a position avoiding the charging assembly 160. The driving component 126 drives the moving component 127 to reciprocate along a predetermined direction by electromagnetic action.

[0074] Specifically, the motor frame 122 is used to provide support and protection for the internal structure of the motor such as the driving component 126 and the moving component 127. The number of the driving component 126 and the moving component 127 can be one, two or more. The driving component 126 can be fixedly installed in the motor frame 122 or can be suspended in the motor frame 122 by a base and a spring piece or the like. In this way, the driving component 126 and the moving component 127 can move relative to each other to buffer the vibration of the driving component 126 and the moving component 127, reduce the vibration transmitted to the motor frame 122, and thus weaken the vibration feeling of the electric shaver 100. The moving component 127 can be suspended on the motor frame 122 or the base by a spring piece, a flexible piece or the like.

[0075] The driving component 126 is used to drive the moving component 127 to reciprocate along a predetermined direction, and the motor is a linear motor. It can be understood that the moving component 127 includes a permanent magnet and a connecting seat, and the permanent magnet is fixed to the connecting seat, and the connecting seat forms an output end of the motor. The driving component 126 includes an iron core, a bobbin and a coil 1261 wound on the bobbin, and the bobbin is mounted on the iron core. The iron core can be a U-shaped iron core, an E-shaped iron core or the like, and different types of iron cores can be selected according to actual needs, which are not limited here. After the coil 1261 passes through the alternating current, the driving component 126 forms an electromagnet, and through the magnetic induction action of the electromagnet and the permanent magnet of the moving component 127, the moving component 127 is driven to reciprocate along a predetermined direction.

[0076] The conductive adapter plate 123 refers to a conductive structure in a substantially plate shape. The conductive adapter plate 123 can be a regular plate shape such as a circular shape or a rectangular shape, or an irregular plate shape with notches and the like. The conductive adapter plate 123 can be directly fixed to the motor frame 122, or indirectly fixed to the motor frame 122 through a mounting plate 1291 and the like. Specifically, the conductive wire 125 is electrically connected to the coil 1261 of the driving component 126. The conductive wire 125 can be directly electrically connected to the lead end 1262 of the coil 1261, or electrically connected through a conductive plate 1292 or other conductive structure.

[0077] The first conductive part 124 can be a conductive column, a conductive cylinder, or other conductive structures. The first conductive part 124 is electrically connected to the conductive adapter plate 123, and is used to be electrically connected to the power supply unit 140 to provide power for the driving component 126.

[0078] The conductive wire 125 and the conductive adapter plate 123 can be electrically connected through welding or other conductive parts. One end of the conductive wire 125 is electrically connected to the driving component 126, and the other end is electrically connected to the conductive adapter plate 123. The conductive adapter plate 123 has greater hardness compared to the conductive wire 125, and has a large and flat plate surface. By electrically connecting the conductive wire 125 to the plate surface of the conductive adapter plate 123, on the one hand, the conductive adapter plate 123 has a larger contact area, which is more convenient for cable wiring operation. Moreover, compared to the conductive plug column, the conductive adapter plate 123 occupies less space in the longitudinal direction, which can effectively reduce the occupied space of the lead structure in the longitudinal direction of the electric shaver 100, thereby facilitating the miniaturization of the electric shaver 100.

[0079] The above embodiment forms a mounting space 128 by spacing the two first conductive parts 124 on the conductive adapter plate 123. The conductive wire 125 is connected to the conductive adapter plate 123 to avoid the position of the charging assembly 160. The mounting bracket 130 is provided with a through hole 133 corresponding to the charging assembly 160. In this way, the charging assembly 160 can partially pass through the through hole 133 of the mounting bracket 130 to extend into the mounting space 128, i.e., the charging assembly 160 can be located adjacent to the conductive adapter plate 123. By ingeniously using the internal space of the mounting bracket 130 to install the charging assembly 160, the occupied space of the motor 120, the mounting bracket 130, and the charging assembly 160 in the longitudinal direction of the electric shaver 100 can be minimized, thereby reducing the volume of the electric shaver 100 and achieving the miniaturization of the electric shaver.

[0080] In some embodiments, as shown in FIGS. 13-20, two driving components 126 are arranged side by side and spaced apart in the motor frame 122, and two moving components 127 are arranged one by one at the upper ends of the two driving components 126 in the longitudinal direction. The moving direction of the moving components 127 is perpendicular to the side-by-side direction of the two driving components 126. The conductive adapter plate 123 has a first plate surface 1231 facing the charging assembly 160 and a second plate surface 1232 away from the charging assembly. The at least two wires 125 include two first cables 1251 and two second cables 1252. One end of the two first cables 1251 is electrically connected to one of the driving components 126, and the other end is electrically connected to the second plate surface 1232 or the first plate surface 1231 away from the charging assembly 160. One end of the two second cables 1252 is electrically connected to the other driving component 126, and the other end is electrically connected to the second plate surface 1232 or the first plate surface 1231 away from the charging assembly 160.

[0081] The above embodiments can effectively improve the shearing efficiency by arranging two driving components 126 and two moving components 127. The moving directions of the two moving components 127 can be the same or opposite. Alternatively, the moving directions of the two moving components 127 are opposite. In this way, the vibrations generated by the two moving components 127 can be partially offset, thereby weakening the vibration of the entire motor 120. The two first cables 1251 are positive and negative wires, respectively, and the two second cables 1252 are also positive and negative wires, respectively. Thus, the two first cables 1251 and the two second cables 1252 electrically connected to the two driving components 126 are electrically connected to the plate surface of the conductive adapter plate 123, which can further reduce the space occupied by the lead structure in the longitudinal direction of the electric shaver 100, and can reduce the alignment difficulty of the wires 125 and improve the convenience of the wire 125 connection operation. At the same time, the first cable 1251 and the second cable 1252 are connected to the conductive adapter plate 123 away from the charging assembly 160, which can reserve more space for the charging assembly 160 and avoid structural interference.

[0082] In some embodiments, as shown in FIGS. 14, 15, 16-18, 21 and 22, the two first cables 1251 are electrically connected to the first plate surface 1231 away from the charging assembly 160, and the two second cables 1252 are electrically connected to the second plate surface 1232. The two first cables 1251, the first plate surface 1231, and the two first conductive parts 124 together form an installation space 128.

[0083] Specifically, if the first cable 1251 and the second cable 1252 are both connected to the first plate surface 1231 of the conductive adapter plate 123, the middle space of the first plate surface 1231 will be occupied, so that the charging assembly 160 cannot be arranged adjacent to the conductive adapter plate 123, which is not conducive to reducing the longitudinal height of the electric shaver 100. If the first cable 1251 and the second cable 1252 are both connected to the second plate surface 1232 of the conductive adapter plate 123, in order to facilitate wiring, the spacing between the second plate surface 1232 and the motor frame 122 needs to be set to be larger, which will increase the occupied space of the wire 125 structure in the longitudinal direction of the electric shaver 100.

[0084] In the above embodiments, by electrically connecting the first cable 1251 and the second cable 1252 to the first plate surface 1231 and the second plate surface 1232 of the conductive adapter plate 123 respectively, compared with electrically connecting the first cable 1251 and the second cable 1252 to the same plate surface of the conductive adapter plate 123, the occupied space of the wire 125 structure in the longitudinal direction of the electric shaver 100 can be reduced, so that the internal structure of the electric shaver 100 can be arranged more compactly in the longitudinal direction, thereby reducing the longitudinal size of the electric shaver 100, which is conducive to the miniaturization of the electric shaver 100.

[0085] In some embodiments, as shown in FIGS. 11-15 and 17-22, one end of each of the two first cables 1251 is electrically connected to two ends of the first plate surface 1231 in a preset direction, and the two first conductive parts 124 are arranged at two ends of the first plate surface 1231 in a side-by-side direction (hereinafter referred to as the side-by-side direction) of the two drive components 126.

[0086] In the above embodiments, one end of each of the two first cables 1251 is electrically connected to two ends of the first plate surface 1231 in a preset direction, which can make the length and curvature of the bending section 1253 of the first cable 1251 larger, can disperse stress, avoid stress concentration, and relieve stress fatigue of the first cable 1251 caused by long-time vibration of the drive component 126, thereby improving the service life of the first cable 1251. One end of each of the two first cables 1251 is electrically connected to two ends of the first plate surface 1231 in a preset direction, and the two first conductive parts 124 are arranged at two ends of the first plate surface 1231 in the side-by-side direction, so that the electrical connection points of the two first cables 1251 and the first plate surface 1231, and the two first conductive parts 124 are arranged adjacent to the four sides of the conductive adapter plate 123, which can maximize the size of the mounting space 128 formed by the first cable 1251, the first plate surface 1231 and the two first conductive parts 124, thereby facilitating the assembly of the charging assembly 160 in the mounting space 128.

[0087] Further, the two first conductive parts 124 are located at the middle part of the first plate surface 1231 in the preset direction. The conductive parts are arranged in the middle part of the first plate surface 1231, so that the overall layout is more reasonable and compact.

[0088] In some embodiments, referring to FIGS. 16-20, one end of each of the two second cables 1252 is electrically connected to the two ends of the second plate surface 1232 in the preset direction. The electric shaver 100 further comprises a wire fixing structure 1233 arranged at the two ends of the conductive adapter plate 123 in the preset direction. The wire fixing structure 1233 has a first wire fixing part 12331 protruding from the first plate surface 1231 and a second wire fixing part 12332 protruding from the second plate surface 1232. One end of each of the two first cables 1251 passes through the two first wire fixing parts 12331, and one end of each of the two second cables 1252 passes through the second wire fixing part 12332.

[0089] In the above embodiments, one end of each of the two second cables 1252 is electrically connected to the two ends of the second plate surface 1232 in the preset direction, so that the length and the curvature of the bending section 1253 of the second cable 1252 are larger, the stress can be dispersed, and stress concentration can be avoided, so as to relieve the stress fatigue of the second cable 1252 caused by the long-time vibration of the driving component 126, and further improve the service life of the second cable 1252.

[0090] It can be understood that the wire fixing structure 1233 is made of insulating material. The first wire fixing part 12331 and the second wire fixing part 12332 are connected to each other and pass through the conductive adapter plate 123. The first cable 1251 and the second cable 1252 are fixed on the same wire fixing structure 1233, so that the installation of the wire fixing structure 1233 can be simplified. The first wire fixing part 12331 and the second wire fixing part 12332 are used for positioning and limiting the connection end of the first cable 1251 and the second cable 1252 with the conductive adapter plate 123, respectively, so that the connection end of the first cable 1251 and the second cable 1252 is kept in the position adjacent to the conductive adapter plate 123, which can avoid the displacement of the first cable 1251 and the second cable 1252 during welding, and facilitate the electrical connection between the first cable 1251, the second cable 1252 and the conductive adapter plate 123. At the same time, since the electrical connection end of the first cable 1251 and the second cable 1252 with the conductive adapter plate 123 is clamped by the second wire fixing part 12332 and the first wire fixing part 12331, the electrical connection end of the first cable 1251 and the second cable 1252 with the conductive adapter plate 123 can be kept in the connection position, so as to avoid the disconnection of the connection point caused by long-time vibration.

[0091] The structure of the first wire fixing part 12331 and the second wire fixing part 12332 can be various, for example, the first wire fixing part 12331 and the second wire fixing part 12332 can be crimping blocks, and perforations are arranged on the crimping blocks for the wires 125 to pass through, so as to realize the crimping of the wires 125 on the surface of the conductive adapter plate 123. The specific structure of the wire fixing structure 1233 can be selected and designed according to actual needs, which is not limited here.

[0092] In some embodiments, as shown in FIGS. 17-20 and FIG. 22, the first cable 1251 and the second cable 1252 each have a bending section 1253, and the bending sections 1253 of the first cable 1251 and the second cable 1252 are oppositely bent in the first direction.

[0093] If the bending sections 1253 of the first cable 1251 and the second cable 1252 are bent towards the same side of the first direction, the first cable 1251 and the second cable 1252 need to be vertically staggered between the motor frame 122 and the conductive adapter plate 123, so that the space occupied by the lead structure in the height direction of the electric shearing device is increased. If the bending sections 1253 of the first cable 1251 and the second cable 1252 are oppositely bent in the first direction, so that the bending sections 1253 are mostly sandwiched between the motor frame 122 and the conductive adapter plate 123, it is easy to interfere with other components, and the wire fixing difficulty is increased.

[0094] The oppositely bent bending sections 1253 of the first cable 1251 and the second cable 1252 in the first direction means that the opening directions of the bending sections 1253 of the first cable 1251 and the second cable 1252 are oppositely arranged on the opposite sides of the conductive adapter plate 123 in the first direction. For ease of description, the two driving components 126 are defined as a first driving component 126 and a second driving component 126, one end of the first cable 1251 is electrically connected to the first driving component 126, and the bending section 1253 of the first cable 1251 is bent towards the second driving component 126, one end of the second cable 1252 is electrically connected to the second driving component 126, and the bending section 1253 of the second cable 1252 is bent towards the first driving component 126.

[0095] In this way, compared with the same side bending of the bending sections 1253 of the first cable 1251 and the second cable 1252 towards the first direction, the portions of the first cable 1251 and the second cable 1252 between the motor frame 122 and the conductive adapter plate 123 can be arranged side by side along the plate surface, without occupying additional space in the height direction of the electric shaver. Compared with the bending of the bending sections 1253 of the first cable 1251 and the second cable 1252 in the first direction respectively, the length of the extension of the first cable 1251 along the first plate surface 1231 of the conductive adapter plate 123 and the length of the extension of the second cable 1252 along the second plate surface 1232 of the conductive adapter plate 123 can be increased, the contact length and area of the first cable 1251 and the first plate surface 1231, and the contact length and area of the second cable 1252 and the second plate surface 1232 can be increased, and the strength and reliability of the electrical connection points of the cables and the conductive adapter plate 123 can be further improved.

[0096] In some embodiments, referring to FIG. 16 and FIG. 20, the electric shaver 100 further comprises a mounting plate 1291 connected between the two wire fixing structures 1233, the mounting plate 1291 is fixed to one end of the motor frame 122 towards the charging assembly 160, and the second plate surface 1232 is fixedly mounted to the plate surface of the mounting plate 1291 towards the charging assembly 160.

[0097] In the above embodiments, the mounting plate 1291 is made of insulating material. The mounting plate 1291 can be fixedly connected to the motor frame 122 by screws or other structures. The conductive adapter plate 123 can also be fixedly connected to the mounting plate 1291 by screws. Alternatively, the motor 120 further comprises a connecting piece, which is sequentially arranged through the conductive adapter plate 123 and the mounting plate 1291 and fixedly connected to the motor frame 122. In this way, the connecting piece can simultaneously connect the conductive adapter plate 123, the mounting plate 1291 and the motor frame 122, and the fixed connection structure of the three can be simplified.

[0098] In order to improve the connection strength, the two wire fixing structures 1233 are optionally integrally formed with the mounting plate 1291. The two wire fixing structures 1233 are fixedly connected to the motor frame 122 through the mounting plate 1291, and the mounting of the parts can be simplified. The conductive adapter plate 123 is fixedly connected to the plate surface of the mounting plate 1291 towards the charging assembly 160, and the motor frame 122 and the conductive adapter plate 123 can be separated by the mounting plate 1291. The first cable 1251 and the second cable 1252 can be prevented from contacting the conductive adapter plate 123 at the electrical connection end of the driving component 126, thereby reducing the risk of short circuit and improving the safety and reliability of the product in use.

[0099] In some embodiments, referring to FIGS. 11-15, the housing 110 has a mounting opening 111 opposite a bottom wall 112 in the longitudinal direction, and the mounting bracket 130 has a second conductive portion 134 embedded in the bottom surface in the longitudinal direction, which is electrically connected to the main control board 151. The charging assembly 160 includes a charging bracket 161, a charging circuit board 162, and a third conductive portion 163. The charging bracket 161 is connected to the bottom wall 112, the charging circuit board 162 is arranged on the top wall of the charging bracket 161 close to the mounting bracket 130, the third conductive portion 163 is electrically connected to the charging circuit board 162, and the third conductive portion 163 and the second conductive portion 134 are detachably connected in the longitudinal direction.

[0100] Specifically, the housing 110 has a mounting opening 111 and a bottom wall 112 opposite in the longitudinal direction, providing a channel for longitudinal mounting and dismounting, which facilitates quick disassembly and assembly of the internal components by the user. The bottom of the mounting bracket 130 can be appropriately thickened to embed the second conductive portion 134, providing certain mechanical strength. The second conductive portion 134 is electrically connected to the main control board 151, so that the main control board 151 can be electrically connected to the charging assembly 160 through the second conductive portion 134.

[0101] The charging assembly 160 is electrically connected to the second conductive portion 134 through the third conductive portion 163. The second conductive portion 134 is embedded in the bottom surface of the mounting bracket 130 and is mainly used for electrical connection with the third conductive portion 163 of the charging assembly 160. In this way, the second conductive portion 134 provides a quick disassembly and assembly electrical interface, avoiding the traditional wire welding method and simplifying the assembly and maintenance process. At the same time, the second conductive portion 134 is embedded in the bottom surface of the mounting bracket 130, so that the two are closely combined, avoiding the problem of poor electrical contact caused by loosening or movement of the second conductive portion 134.

[0102] The third conductive portion 163 can be mounted on the charging circuit board 162 or the charging bracket 161 and is inserted into the second conductive portion 134 to achieve electrical connection between the charging assembly 160 and the main control board 151. Through the longitudinal insertion, the third conductive portion 163 enables the charging assembly 160 to be quickly disassembled and assembled. One of the second conductive portion 134 and the third conductive portion 163 can be provided as a pin type, a spring type, or other types of electrical connectors, and the other is provided to cooperate with the second conductive portion 134 to ensure stability during insertion.

[0103] The above embodiments are configured by arranging the housing 110 with the mounting opening 111 and the bottom wall 112 in the longitudinal direction, so that the components of the device can be mounted and dismounted by longitudinal plug-in. By fixing the second conductive part 134 on the bottom surface of the mounting bracket 130, and aligning the third conductive part 163 with the second conductive part 134 in the longitudinal direction and plugging, the charging assembly 160 can be mounted with the mounting bracket 130 through the mounting opening 111, while realizing the electrical connection between the charging circuit board 162 of the charging assembly 160 and the main control board 151 fixedly mounted on the mounting bracket 130, thereby realizing the quick disassembly of the charging circuit board 162 and the main control board 151. Compared with the traditional welding method, the longitudinal plug-in design makes the installation and disassembly of the module more convenient. The disassembly can be completed by simple plug-in operation, and the user does not need to weld or perform complex tool operation in a narrow space, nor needs to operate in the transverse direction or other complex directions, which greatly simplifies the maintenance and repair work of the device. For example, first, the charging bracket 161 is mounted on the bottom wall 112, then the main control board 151 is mounted on the mounting bracket 130, then the second conductive part 134 is embedded on the bottom surface of the mounting bracket 130 in the longitudinal direction, then the third conductive part 163 is electrically connected to the charging circuit board 162, and finally the second conductive part 134 of the mounting bracket 130 is aligned with the third conductive part 163 for plug-in, thereby completing the assembly.

[0104] Secondly, by embedding the second conductive part 134 on the bottom surface of the mounting bracket 130, the second conductive part 134 is prevented from protruding inside the mounting bracket 130 or occupying additional space, so that the second conductive part 134 can be integrated with the bottom surface of the mounting bracket 130, effectively saving the space inside the device, and being conducive to the miniaturization and internal structure optimization of the device.

[0105] In addition, since the main control board 151 is located on the side wall of the mounting bracket 130, and the charging circuit board 162 is arranged on the top wall of the charging bracket 161, i.e., the main control board 151 and the charging circuit board 162 are mounted in different directions, the stacking of the main control board 151 and the charging circuit board 162 in the same direction is prevented, thereby avoiding the problem that the device is large in size in a certain direction, which is not conducive to the miniaturization of the device.

[0106] In some embodiments, referring to FIGS. 3-7, 9 and 10, the charging assembly 160 further includes a charging socket 164. One end of the charging bracket 161 towards the conductive adapter plate 123 partially extends into the via 133, and the charging socket 164 is mounted on the charging bracket 161. The charging bracket 161 is transversely provided with a fixed protrusion 1611 below the second conductive part 134, and the fixed protrusion 1611 is provided with two third conductive parts 163 corresponding to the two second conductive parts 134 for electrical connection, and the two third conductive parts 163 are electrically connected to the charging circuit board 162.

[0107] In the above embodiment, by adopting the second conductive part 134 and the third conductive part 163 to electrically connect the mounting bracket 130 and the charging assembly 160, after the mounting bracket 130 is installed in the inner cavity of the shell 110, the second conductive part 134 on the mounting bracket 130 can be directly and correspondingly electrically connected with the third conductive part 163 of the charging assembly 160. In this way, when the charging assembly 160 is connected with an external power supply, the power supply on the mounting bracket 130 can be charged, which greatly simplifies the electrical connection step and improves the assembly efficiency of the whole machine.

[0108] The charging bracket 161 can be fixedly connected with the bottom wall of the shell 110, or can be detachably connected. The charging socket 164 is installed in the charging bracket 161, which is more conducive to the glue sealing of the charging socket 164. The charging bracket 161 and the charging circuit board 162 extend into the mounting space 128 through the through hole 133 of the mounting bracket 130. It can be understood that, since the charging circuit board 162 extends to a position adjacent to the conductive adapter plate 123, if the charging circuit board 162 is directly electrically connected with the conductive adapter plate 123, the overall height occupied space will be increased. Therefore, the charging bracket 161 is transversely provided with a fixed protrusion 1611 located below the second conductive part 134, and the third conductive part 163 electrically connected with the mounting bracket 130 is arranged on the fixed protrusion 1611. In this way, the charging circuit board 162 can be more closely adjacent to the conductive adapter plate 123, and the height occupied space between the charging assembly 160, the mounting bracket 130 and the motor 120 can be reduced, so as to further reduce the volume of the whole machine.

[0109] In some embodiments, referring to FIGS. 11-15, 21 and 22, the charging assembly 160 further includes a charging socket 164. An end portion of the charging bracket 161 towards the conductive adapter plate 123 extends into the through hole 133, and the charging socket 164 is installed on the charging bracket 161. The charging bracket 161 is transversely provided with a fixed protrusion 1611 located below the second conductive part 134, and two third conductive parts 163 electrically connected with the two second conductive parts 134 one by one are arranged on the fixed protrusion 1611. The two third conductive parts 163 are electrically connected with the charging circuit board 162.

[0110] In the above embodiment, by adopting the second conductive part 134 and the third conductive part 163 to electrically connect the mounting bracket 130 and the charging assembly 160, after the mounting bracket 130 is installed in the inner cavity of the shell 110, the second conductive part 134 on the mounting bracket 130 can be directly and correspondingly electrically connected with the third conductive part 163 of the charging assembly 160. In this way, when the charging assembly 160 is connected with an external power supply, the power supply on the mounting bracket 130 can be charged, which greatly simplifies the electrical connection step and improves the assembly efficiency of the whole machine.

[0111] The charging support 161 can be fixedly connected with the bottom wall of the shell 110, or can be detachably connected. The charging female socket 164 is installed in the charging support 161, which is more conducive to the glue sealing of the charging female socket 164. The charging support 161 and the charging circuit board 162 extend into the mounting space 128 through the through hole 133 of the mounting support 130. It can be understood that, since the charging circuit board 162 extends to a position adjacent to the conductive adapter plate 123, if the charging circuit board 162 is directly electrically connected with the conductive adapter plate 123, the overall height occupied space will be increased. Therefore, the charging support 161 is transversely provided with a fixed protrusion 1611 located below the second conductive part 134, and a third conductive part 163 electrically connected with the mounting support 130 is arranged on the fixed protrusion 1611. In this way, the charging circuit board 162 can be more closely adjacent to the conductive adapter plate 123, thereby reducing the height occupied space among the charging assembly 160, the mounting support 130 and the motor 120, so as to further reduce the overall volume.

[0112] In some embodiments, referring to FIGS. 9 and 10, two second accommodating cavities 132 are arranged on opposite sides of the first accommodating cavity 131 along a first direction perpendicular to the longitudinal direction. The mounting support 130 further includes a plurality of insertion parts 135, each of which is protrudingly arranged on the side surface of the mounting support 130 where the slot is located. At least one insertion part 135 is arranged on the bottom side of the mounting support 130 in the longitudinal direction, and at least one insertion part 135 is arranged on each of the opposite edges of the mounting support 130 in the first direction. The main control board 151 slides along the longitudinal direction from the top side of the mounting support 130 to the space between the plurality of insertion parts 135, so as to cover the slot of the second accommodating cavity 132.

[0113] Specifically, the insertion part 135 can be a clamping groove, and the edge of the main control board 151 can be inserted into the clamping groove to achieve limiting and fixing. The insertion part 135 can also be a buckle, which can lock the main control board 151 after insertion to prevent it from sliding out. The insertion part 135 is protrudingly arranged on the side surface of the mounting support 130 where the slot is located, and is located on the outer edge of the mounting support 130. In this way, the main working area inside the shell 110 can not be occupied, so the space can be more effectively utilized, and other internal components can be avoided from being interfered.

[0114] The main control board 151 slides along the longitudinal direction from the top side of the mounting support 130 to the space between the plurality of insertion parts 135, so as to cover the slot of the second accommodating cavity 132. This mounting method means that during assembly, the main control board 151 will naturally slide to the correct position by gravity, and the limiting fit will ensure the accuracy and stability of the connection. Compared with other assembly methods such as forced pressing or using tools for fixing, gravity assembly is more gentle. This helps to reduce problems caused by excessive stress or damage to parts, prolongs the service life and reliability of the equipment.

[0115] Optionally, as shown in FIG. 9 and FIG. 10, the slot of the second accommodating cavity 132 can face a second direction, which is perpendicular to the first direction and perpendicular to the longitudinal direction.

[0116] In some embodiments, the length of the second accommodating cavity 132 in the longitudinal direction is greater than the length in the first direction and the length in the second direction. Specifically, the second accommodating cavity 132 extends in the longitudinal direction, and the length in the longitudinal direction is greater than the length in the first direction and the length in the second direction, so that the size of the electric shaver 100 in the first direction and the second direction can be reduced, thereby reducing the volume of the electric shaver 100.

[0117] In some embodiments, as shown in FIG. 10, each plug-in part 135 includes a connecting segment 1351 connected to the mounting bracket 130 and a limiting segment 1352 connected to the end of the connecting segment 1351 away from the mounting bracket 130, and the limiting segment 1352 is used to abut the surface of the main control board 151 away from the mounting bracket 130.

[0118] In the above embodiments, the limiting segment 1352 abuts the main control board 151, which can reduce the movement of the main control board 151 on the mounting bracket 130, thereby improving the stability of the entire system. At the same time, the connecting segment 1351 and the limiting segment 1352 form a clamping groove, and the edge of the main control board 151 is inserted into the clamping grooves, which can simplify the assembly process of the main control board 151, and the existence of the limiting segment 1352 makes it easier for the main control board 151 to be aligned and fixed on the mounting bracket 130.

[0119] In some embodiments, as shown in FIG. 9 and FIG. 10, the mounting bracket 130 is further provided with two guide plates 136, and the two guide plates 136 are respectively arranged on the opposite edges of the mounting bracket 130 in the first direction and protrude from the side surface of the slot of the second accommodating cavity 132.

[0120] In the above embodiments, the guide plates 136 clearly define the assembly path of the main control board 151 in the longitudinal direction, thereby simplifying the installation steps of the main control board 151. At the same time, the guide plates 136 provide stability and safety for assembly in the first direction. Specifically, the two sides of the main control board 151 in the first direction are limited by the two guide plates 136, and the guide plates 136 limit the movement of the main control board 151, thereby reducing the possibility of accidents during assembly, such as accidental falling or misoperation of the main control board 151.

[0121] In some embodiments, referring to Figs. 3-6, 13-16 and 23, the electric shaver 100 further comprises an end cover 170 mounted at the mounting opening 111. The bottom wall 112 is provided with a charging port 113 corresponding to the charging assembly 160. The mounting bracket 130 comprises a base 1301 and a support frame 1302, which together form a first accommodating cavity 131, a second accommodating cavity 132 is formed on the support frame 1302, and a second conductive part 134 is arranged on the side of the base 1301 facing the bottom wall 112. The side of the base 1301 facing the end cover 170 is provided with a fourth conductive part 137, which is electrically connected with the power supply unit 140. The first conductive part 124 is electrically connected with the fourth conductive part 137.

[0122] Specifically, the end cover 170 is detachably mounted at the mounting opening 111. It should be noted that the end cover 170 includes but is not limited to a rectangle similar in shape to the bottom wall 112. The bottom wall 112 is provided with a charging port 113 in the middle for charging, which corresponds to the charging assembly 160, so that the charging assembly 160 is connected to the charging port 113 on the bottom wall 112.

[0123] The mounting bracket 130 specifically comprises a base 1301 and a support frame 1302, the base 1301 is the bottom of the mounting bracket 130 as shown in Figs. 5 and 6, and the support frame 1302 is the part extending upward at the left and right ends of the base 1301, the base 1301 and the support frame 1302 surround to form a first accommodating cavity 131, and the support frame 1302 forms a second accommodating cavity 132, i.e. the power supply unit 140 is installed inside the support frame 1302. The second conductive part 134 is arranged on the side of the base 1301 facing the bottom wall 112, i.e. the second conductive part 134 is arranged on the lower end surface of the base 1301. The side of the base 1301 facing the end cover 170 is also provided with a fourth conductive part 137, and the second conductive part 134 and the fourth conductive part 137 are respectively electrically connected with the power supply unit 140 in the support frame 1302. When charging the power supply unit 140, the power supply unit 140 can be sequentially charged through the third conductive part 163 and the second conductive part 134. The first conductive part 124 is electrically connected with the fourth conductive part 137. That is, when the power supply unit 140 discharges, the driving component 126 can be sequentially powered through the fourth conductive part 137 and the first conductive part 124.

[0124] It should be noted that the assembly sequence of the electric shaver 100 described above includes but is not limited to: connecting the motor 120 to the left and right ends of the end cover 170, then connecting the mounting bracket 130 to the left and right ends of the end cover 170, and making the motor 120 in the first accommodating cavity 131; electrically connecting the fourth conductive part 137 and the first conductive part 124; then fixing the charging assembly 160 on the bottom wall 112 and electrically connecting it with the charging port 113; finally, connecting the end cover 170 with the shell 110, and making the mounting bracket 130 in the shell 110, and electrically connecting the second conductive part 134 and the third conductive part 163.

[0125] In the above embodiment, by assembling several electronic devices into a single modular, the modular components are assembled and electrically connected, which is more convenient and efficient than assembling several electronic devices one by one. The convenient and efficient assembly improves production efficiency. After modular assembly, it is also more convenient to disassemble than assembling several electronic devices one by one, which facilitates post-sale maintenance and reduces maintenance costs.

[0126] In an embodiment, the first conductive part 124 and the fourth conductive part 137 can be provided with two, and the two first conductive parts 124 and the two fourth conductive parts 137 are electrically connected one by one. Among them, the fourth conductive part 137 can be directly connected with the power supply unit 140, or indirectly connected through the main control board 151. In this way, after the motor 120 is installed in the first accommodating cavity 131 of the mounting bracket 130, the first conductive part 124 on the conductive adapter plate 123 of the motor 120 can be directly electrically connected with the fourth conductive part 137 on the mounting bracket 130, so that the power supply unit 140 can supply power to the driving component 126, which can greatly simplify the electrical connection step and improve the assembly efficiency of the whole machine.

[0127] In some embodiments, the first conductive part 124 and the fourth conductive part 137 are detachably electrically connected. Referring to FIG. 13, one of the first conductive part 124 and the fourth conductive part 137 is a conductive column, and the other is a conductive cylinder that is adaptively plugged with the conductive column. By such arrangement, the mounting bracket 130 and the motor 120 are detachably electrically connected, further improving the convenience of disassembly and electrical connection of the two.

[0128] Further, as shown in FIG. 13, the fourth conductive part 137 can be a conductive cylinder, the first conductive part 124 can be a conductive column, and the first conductive part 124 and the fourth conductive part 137 are each provided with at least two, so that each first conductive part 124 is plugged with each fourth conductive part 137 one by one.

[0129] In some embodiments, the second conductive part 134 and the third conductive part 163 are detachably electrically connected. Referring to FIG. 12, one of the second conductive part 134 and the third conductive part 163 is a conductive cylinder, and the other is a conductive barrel that is adapted to be plugged into the conductive cylinder. In this way, the mounting bracket 130 and the charging assembly 160 are detachably electrically connected, further improving the convenience of disassembly and electrical connection of the two.

[0130] Further, as shown in FIG. 12, the second conductive part 134 can be a conductive barrel, the third conductive part 163 can be a conductive cylinder, and the second conductive part 134 and the third conductive part 163 are each provided with at least two, so that each third conductive part 163 is plugged into each second conductive part 134 one by one.

[0131] In the above embodiment, the second conductive part 134 and the fourth conductive part 137 are provided as conductive barrels, the third conductive part 163 and the first conductive part 124 are provided as conductive cylinders that are respectively plugged into the second conductive part 134 and the fourth conductive part 137, the positions of the second conductive part 134 and the third conductive part 163 correspond to each other, and the positions of the fourth conductive part 137 and the first conductive part 124 correspond to each other. When assembling the electric shaver 100, the third conductive part 163 is directly plugged into the hole position of the second conductive part 134, and the first conductive part 124 is directly plugged into the hole position of the fourth conductive part 137, so that the electrical connection is more convenient during assembly, and the assembly is more convenient compared to when not provided as a conductive barrel and a conductive cylinder. At the same time, by providing the cooperation of the conductive barrel and the conductive cylinder, the conductive cylinder abuts the inner wall in the hole position of the conductive barrel, so that the electrical connection after assembly is more stable.

[0132] Further, referring to FIGS. 12 and 13, the bottom seat 1301 is provided with at least two first mounting positions 1301a on the side facing the bottom wall 112, and at least two second conductive parts 134 are plugged and fixed one by one corresponding to each first mounting position 1301a. The bottom seat 1301 is provided with at least two second mounting positions 1301b on the side facing the end cover 107, and at least two fourth conductive parts 137 are plugged and fixed one by one corresponding to each second mounting position 1301b.

[0133] Specifically, at least two first mounting positions 1301a are provided on the lower end surface of the bottom seat 1301, and each of the aforementioned second conductive parts 134 is plugged and fixed one by one in one first mounting position 1301a. At least two second mounting positions 1301b are provided on the upper end surface of the bottom seat 1301, and each of the aforementioned fourth conductive parts 137 is plugged and fixed one by one in one second mounting position 1301b. It should be noted that the number of first mounting positions 1301a corresponds to the number of second conductive parts 134, and the number of second mounting positions 1301b corresponds to the number of fourth conductive parts 137. In addition, the first mounting position 1301a and the second mounting position 1301b include but are not limited to circular mounting holes.

[0134] In the above embodiment, when the second conductive part 134 and the fourth conductive part 137 are respectively fixed in the first mounting position 1301a and the second mounting position 1301b on the base 1301, the second conductive part 134 and the fourth conductive part 137 are more stable and less likely to fall off than when the second conductive part 134 and the fourth conductive part 137 are directly provided on the two end faces of the base 1301.

[0135] Further, the first conductive part 124, the second conductive part 134, the third conductive part 163, and the fourth conductive part 137 all extend in the direction from the mounting opening 111 to the bottom wall 112.

[0136] Specifically, the first conductive part 124, the second conductive part 134, the third conductive part 163, and the fourth conductive part 137 are all arranged in the longitudinal direction. In assembly, the third conductive part 163 is inserted and fitted with the second conductive part 134, and the first conductive part 124 is inserted and fitted with the fourth conductive part 137. By arranging the first conductive part 124, the second conductive part 134, the third conductive part 163, and the fourth conductive part 137 in the longitudinal direction, it is convenient for insertion and fitting in assembly. Alternatively, in some embodiments, the two fourth conductive parts 137 are arranged in the side-by-side direction (or the second direction in some embodiments) as shown in FIG. 13.

[0137] Further, the first mounting position 1301a and the second mounting position 1301b can be provided at the edge region of the base 1301. Specifically, the first mounting position 1301a and the second mounting position 1301b are respectively provided at the edge region of the base 1301, and on opposite sides in the first direction as shown in FIG. 9, so that the two second conductive parts 134 are respectively located at the edge regions on the left and right sides of the base 1301, and the two second mounting positions 1301b are located at the rear edge position of the base 1301, so that the two fourth conductive parts 137 are respectively located at the rear side of the base 1301.

[0138] In the above embodiment, by arranging the first mounting position 1301a and the second mounting position 1301b at the edge position of the base 1301, the second conductive part 134 and the fourth conductive part 137 are both arranged at the edge position of the base 1301, so that the stacked structure after assembly is more compact and the overall volume is reduced.

[0139] It should be noted that the at least two second conductive parts 134 are respectively arranged at both ends in the first direction as shown in FIG. 9 on the base 1301, and the at least two fourth conductive parts 137 are arranged at one end in the first direction on the base 1301, for example, can be arranged at the left end in the first direction on the base 1301.

[0140] Optionally, the at least two fourth conductive parts 137 are between the at least two second conductive parts 134, i.e. two second conductive parts 134 are at the left and right ends of the base 1301, and two fourth conductive parts 137 are between the two second conductive parts 134.

[0141] Optionally, the second conductive part 134 and the fourth conductive part 137 are respectively arranged on opposite sides of the base 1301, i.e. the second conductive part is arranged at the front of the base 1301, and the third conductive part is arranged at the back of the base 1301.

[0142] In the above embodiment, the second conductive part 134 is arranged at the two ends of the front of the base 1301, the fourth conductive part 137 is arranged at the left end of the back of the base 1301, and the two fourth conductive parts 137 are between the two second conductive parts 134, so that the second conductive part 134 and the fourth conductive part 137 are specifically distributed, so that the positions of the second conductive part 134 and the fourth conductive part 137 are more easily determined during later disassembly and maintenance. In some embodiments, referring to FIG. 4, the motor frame 122 and the support frame 1302 are respectively fixedly connected to the inner side of the end cover 170. By designing in this way, compared with the case where the motor frame is first fixed on the mounting support and then fixed with the shell, the above embodiment directly connects the motor frame 122 to the inner side of the end cover 170, reducing the intermediate parts of the motor 120. Fewer intermediate parts means that the deviation that may occur during assembly is reduced, thereby improving the overall precision and consistency of the assembly of the motor 120. This helps to ensure that the various parts of the electric shaver 100 fit together more tightly, reducing potential sources of error.

[0143] In addition, the support frame 1302 in the mounting support 130 is also fixedly connected with the end cover 170. In this way, the motor 120 and the mounting support 130 are both assembled with the cover 180 as the positioning reference, thereby ensuring that the positions and positioning references of the motor 120 and the mounting support 130 are relatively fixed and consistent, thereby further reducing the accumulation of errors during processing and installation.

[0144] Optionally, a gap can be formed between the motor frame 122 and the support frame 1302. In this way, when the electric shaver 100 is working, the vibration generated by the motor 120 will not be directly transmitted to the mounting support 130 and the components (such as the main control board 151) fixed on the mounting support 130, thereby reducing the influence of the vibration of the motor 120 and maintaining the stability of the electric shaver 100. In addition, the motor frame 122 and the support frame 1302 are respectively fixedly connected to the end cover 170 and a gap is formed therebetween, which helps to enhance the flexibility of assembly and improve production efficiency and assembly quality. During installation and adjustment, the gap between the motor frame 122 and the support frame 1302 can be more flexibly adjusted to ensure optimal positioning and connection.

[0145] In some embodiments, as shown in FIGS. 4-8 and 24-27, the inner side of the end cover 170 is provided with a first mounting base 171, the first accommodating cavity 131 has a first opening facing the end cover 170, and the motor frame 122 passes through the first opening to be fixedly connected with the first mounting base 171. The second accommodating cavity 132 has a second opening facing away from the end cover 170, and the power supply unit 140 is installed in the second accommodating cavity 132 through the second opening.

[0146] The above embodiments can provide positioning reference for the motor 120 by installing the motor frame 122 on the first mounting base 171 of the end cover 170, reduce assembly error, and further reduce noise. In addition, by making the second accommodating cavity 132 have a second opening facing away from the end cover 170, the two power supply units 140 are installed in the second accommodating cavity 132 from the bottom, so that the mounting bracket 130 can be provided with a connecting structure at the top to be fixedly connected with the end cover 170.

[0147] In some embodiments, the outer wall surface of the motor 120 is spaced apart from the cavity wall of the first accommodating cavity 131. That is, the motor 120 is directly installed on the end cover 170 instead of being installed on the mounting bracket 130, and the outer wall surface of the motor 120 is spaced apart from the cavity wall of the first accommodating cavity 131, so that a damping space can be formed between the outer wall surface of the motor 120 and the cavity wall of the first accommodating cavity 131, which can effectively prevent the vibration of the motor 120 from being transmitted to the mounting bracket 130.

[0148] In some embodiments, as shown in FIGS. 4-8 and 24-27, the electric shaver 100 further comprises a first fastener 300, the motor frame 122 is provided with a first through hole 1221, and the first fastener 300 is connected with the first mounting base 171 through the first through hole 1221 to fixedly connect the motor 120 and the first mounting base 171.

[0149] In some embodiments, referring again to FIGS. 4-8 and 24-27, the electric shaver 100 further comprises a second fastener 400, the inner side of the end cover 170 is provided with a second mounting base 172 corresponding to the second accommodating cavity 132, the support frame 1302 is provided with a second through hole 1303, and the second fastener 400 is connected with the second mounting base 172 through the second through hole 1303 to fixedly connect the mounting bracket 130 and the second mounting base 172.

[0150] In the above embodiments, the first fastener 300 and the second fastener 400 can specifically be screws. The number of the first fastener 300 and the second fastener 400 can be one or more. The first fastener 300 connects the motor frame 122 and the first mounting base surface 171 of the end cover 170, which can ensure the stability and reliability of the connection between the two, and facilitate the disassembly of the two, thereby facilitating the maintenance of the motor 120. Similarly, the second fastener 400 connects the mounting bracket 130 and the second mounting base surface 172 of the end cover 170, which can ensure the stability and reliability of the connection between the two, and facilitate the disassembly of the two, thereby facilitating the maintenance of the motor 120.

[0151] In some embodiments, as shown in FIG. 28, the electric shaver 100 further comprises a first conductive part 181 and a second conductive part 182. The second conductive part 134 is electrically connected to the main control board 151 through the first conductive part 181, and the third conductive part 163 is electrically connected to the charging circuit board 162 through the second conductive part 182.

[0152] Specifically, the first conductive part 181 is used to electrically connect the main control board 151 and the second conductive part 134, and the material thereof can be a flexible wire or a hard conductive sheet. Similarly, the second conductive part 182 is used to electrically connect the charging circuit board 162 and the third conductive part 163, and the material thereof can be a flexible conductive wire or a hard conductive sheet. The materials of the first conductive part 181 and the second conductive part 182 can be the same or different, which will not be described here.

[0153] Optionally, as shown in FIG. 28, the third conductive part 163 can be longitudinally embedded in the charging bracket 161 instead of being directly arranged on the charging circuit board 162. In this way, the stability of the overall structure can be significantly improved. Moreover, embedding the third conductive part 163 in the charging bracket 161 allows the charging circuit board 162 to maintain a smaller size, which releases more internal space for the installation of other functional components or reduces the size of the device, thereby facilitating the miniaturization design of the device. For example, embedding the third conductive part 163 in the charging bracket 161 allows the third conductive part 163 not to occupy the vertical space of the charging circuit board 162, and the charging circuit board 162 does not need to increase the thickness to improve the connection stability of the charging circuit board 162 and the third conductive part 163, thereby reducing the thickness of the charging assembly 160 and further reducing the overall height of the device.

[0154] In existing electric shavers, multiple circuit boards and other electronic components are connected by FPC (flexible printed circuit board). When connecting, the two ends of the FPC are directly welded to the circuit board or electronic component to be connected. However, since the FPC is flexible, it is not convenient to weld, the welding points are difficult to confirm, and the overall cost of the FPC is high.

[0155] In some embodiments, the first conductive member 181 and the second conductive member 182 are both hard conductive members. Specifically, the first conductive member 181 and the second conductive member 182 can be long strip conductive members or other shaped hard conductive members, which can be made of gold-plated copper or other metal materials with wear resistance and high conductivity, so that the first conductive member 181 can be sleeved on one end of the second conductive part 134 and clamped on the other end of the clamping groove of the main control board 151, and the second conductive member 182 can be sleeved on one end of the third conductive part 163 and inserted into the clamping hole of the charging circuit board 162, and then positioned and welded to improve the assembly efficiency. By such design, compared with the traditional two-end welding by FPC, the assembly process is simplified, the assembly time is reduced, and the assembly efficiency is improved. Secondly, compared with the wiring of the wire and the deformation characteristics of the wire, the use of hard conductive members can reduce the occupied space and facilitate the miniaturization of the device.

[0156] Optionally, the top side of the main control board 151 in the longitudinal direction can abut against the end cover 170. In this way, the main control board 151 is limited in the longitudinal direction by the end cover 170, preventing the main control board 151 from being separated from the top of the mounting bracket 130 in the longitudinal direction, thereby improving the structural stability and reliability of the electric shaver 100.

[0157] In some embodiments, as shown in FIGS. 9, 10 and 29, each support bracket 1302 is provided with a bracket connecting plate 1306 at the end portion facing the end cover 170, and the inner side of the end cover 170 is provided with two bracket fixing parts 173 corresponding to the bracket connecting plates 1306 on the two support brackets 1302, and each bracket connecting plate 1306 is provided with a connecting hole 13061, and the bracket fixing part 173 is provided with a fixing hole 174 corresponding to the connecting hole 13061; the electric shaver 100 further comprises a third fastener 500, which is fixedly connected to the fixing hole 174 through the connecting hole 13061.

[0158] In the above embodiments, the bracket fixing part 173 is firmly connected with the bracket connecting plate 1306 through the third fastener 500, ensuring the stable connection of the end cover 170 and the mounting bracket 130 and preventing loosening during use. The third fastener 500 can be a screw, and the fixing hole 174 can be a threaded hole matched with the screw. Through the cooperation of the third fastener 500, the connecting hole 13061 and the fixing hole 174, the assembly and disassembly can be conveniently carried out, and the assembly efficiency and maintenance convenience are improved.

[0159] Further, referring to FIGS. 9, 10 and 29, the end cover 170 is provided with lugs 175 at opposite ends in the first direction, and the lugs 175 are fixedly connected to the shell 110; each support frame 1302 is provided with two opposite support connecting plates 1306 in the second direction at an end of the end cover 170, and each support fixing portion 173 is arranged between the two opposite support connecting plates 1306;

[0160] The axial directions of the connecting holes 13061 and the fixing holes 174 are both in the second direction, and the third fasteners 500 are fixedly connected to the fixing holes 174 in the second direction through the connecting holes 13061.

[0161] In the above embodiment, the end cover 170 is fixedly connected to the shell 110 through the lugs 175 at the two ends in the first direction, and the connection mode can be screw connection, buckle connection, etc. The two lugs 175 can be offset towards the shell 110, so as to increase the volume of the cavity inside the shell 110. The two support connecting plates 1306 of each support frame 1302 are arranged in the second direction, so that each support fixing portion 173 is arranged between the two opposite support connecting plates 1306, the axial directions of the connecting holes 13061 and the fixing holes 174 are both in the second direction, and the third fasteners 500 are fixedly connected to the fixing holes 174 in the second direction through the connecting holes 13061, which can avoid the interference of the lugs 175 with the fasteners, so that the assembly of the third fasteners 500 is more convenient and the assembly efficiency is improved.

[0162] Further, referring to FIGS. 9, 10 and 29, the end face of the support connecting plate 1306 towards the end cover 170 is a guide inclined surface 13062, the guide inclined surfaces 13062 respectively arranged on the two support frames 1302 are arranged at an angle, and the inner side surface of the end cover 170 is provided with a guide inclined surface 176 corresponding to the guide inclined surface 13062, and the guide inclined surface 176 and the guide inclined surface 13062 are arranged in parallel.

[0163] In the above embodiment, the guide inclined surface 176 and the guide inclined surface 13062 are arranged in parallel or close to parallel. The guide inclined surfaces 13062 respectively arranged on the two support frames 1302 are arranged at an angle, and the guide inclined surface 176 on the inner side surface of the end cover 170 cooperates with the guide inclined surfaces 13062, so that the installation of the support frame 10 can be quickly installed to the preset position, the connecting holes 13061 and the fixing holes 174 are corresponded, and the assembly of the third fasteners 500 is facilitated. The cooperation of the guide inclined surface 13062 and the guide inclined surface 176 improves the alignment accuracy and simplifies the installation process, and improves the assembly efficiency.

[0164] In some embodiments, as shown in FIG. 5, FIG. 6, FIG. 25 and FIG. 27, the mounting bracket 130 further has a first side window 138 between the two second accommodating cavities 132, and the main control board 151 is mounted on the side of the mounting bracket 130 where the first side window 138 is located. The main control board 151 has a clearance notch 1511 corresponding to the first side window 138, and the motor 120 is exposed to the main control board 151 through the first side window 138 and the clearance notch 1511.

[0165] Optionally, the mounting bracket 130 can have two opposite first side windows 138 and second side windows 139. The main control board 151 is mounted on the side of the mounting bracket 130 where the first side window 138 is located, so that the main control board 151 is arranged between the two power supply units 140 and faces the motor 120 while the structure is compact, which can effectively shorten the wiring length.

[0166] It can be understood that the main control board 151 is arranged on the side of the motor 120 in the thickness direction of the shaver, so that the main control board 151 has a clearance notch 1511 corresponding to the first side window 138, and the motor 120 is exposed to the main control board 151 through the first side window 138 and the clearance notch 1511. In other words, the main control board 151 has a surrounding or semi-surrounding structure that surrounds the outer periphery of the motor 120 in the plane where the board surface of the main control board 151 is located. In this way, the main control board 151 does not occupy the size of the electric shaver 100 in the thickness direction at all, so that the thickness of the entire electric shaver 100 is the thickness of the motor 120, which minimizes the thickness of the electric shaver 100 and makes the thickness of the electric shaver 100 extremely thin, greatly reducing the overall size and making it more convenient for users to store and carry. Specifically, the outer wall surface of the main control board 151 and the motor bracket 122 are arranged side by side on the board surface of the main control board 151.

[0167] In some embodiments, the main control board 151 includes two first sections 1512 corresponding to the two second accommodating cavities 132 and a second section 1513 connected to the two first sections 1512, and the second section 1513 is located on the side of the motor 120 away from the output end, i.e., the second section 1513 is arranged corresponding to the connecting plate 185. In this way, the main control board 151 has a U-shaped semi-surrounding structure, which is more convenient for processing and installation.

[0168] In some embodiments, as shown in FIG. 4, FIG. 26 and FIG. 27, the electric shaver 100 further includes an indication circuit board 152, which is arranged on the side of the mounting bracket 130 opposite to the side where the first side window 138 is located (for example, it can be arranged at the second side window 139), i.e., the main control board 151 and the indication circuit board 152 are arranged on opposite sides of the mounting bracket 130. The indication circuit board 152 has an indication lamp, and the housing 110 has a light-transmitting hole corresponding to the indication lamp.

[0169] In the above embodiments, by arranging the main control board 151 and the indication circuit board 152 at the first side window 138 and the second side window 139 of the mounting bracket 130 respectively, the size of the single circuit board can be adapted to the size of the motor 120, so as to avoid the single circuit board exceeding the motor 120 and increasing the size of the whole electric shaver 100. By arranging the main control board 151, the indication circuit board 152 and the two power supply units 140 around the motor 120, the space around the motor 120 is fully utilized, so that the overall structure is more compact, and the miniaturization of the whole machine is further realized. In addition, by mounting the main control board 151, the indication circuit board 152 and the two power supply units 140 on the mounting bracket 130, the modular assembly of the whole machine can be realized, the installation is simplified, and the assembly efficiency of the whole machine is improved.

[0170] Optionally, as shown in FIGS. 5, 25 and 26, the opposite two side walls of the mounting bracket 130 are concavely provided with fixing grooves 1304, and the main control board 151 and the indication circuit board 152 are respectively installed in the two fixing grooves 1304. By arranging the fixing grooves 1304 on the opposite two side walls of the mounting bracket 130 to install the main control board 151 and the indication circuit board 152, that is, after being fixed to the mounting bracket 130, the board surface of the main control board 151 and the indication circuit board 152 does not protrude from the wall surface of the mounting bracket 130, which can reduce the thickness of the electric shaver 100 while protecting the main control board 151 and the indication circuit board 152. The main control board 151 and the indication circuit board 152 can be fixedly installed in the fixing grooves 1304 by means of clamping, inserting, screw connection and the like.

[0171] In some embodiments, as shown in FIGS. 26 and 27, the indication circuit board 152 is arranged at one end of the motor frame 122 of the motor 120 facing the charging assembly 160. The indication circuit board 152 includes a main body 1521 and a protruding portion 1522 arranged on the wall of the main body 1521, and the main body 1521 and the protruding portion 1522 are both provided with indication lights. The motor frame 122 is provided with a recessed portion 1222 corresponding to the protruding portion 1522, and the outer wall of the protruding portion 1522 and the inner wall of the recessed portion 1222 are arranged in a spaced manner.

[0172] In order to meet different indication functions of the electric shaver, two or more than two interval distributed indication lights need to be arranged. In the above embodiment, the indication circuit board 152 comprises a main body 1521 and a protruding portion 1522 arranged on the peripheral wall of the main body 1521, and the indication lights are arranged on the main body 1521 and the protruding portion 1522. In this way, two or more than two indication lights can be formed, and the volume of the main body 1521 can be minimized, thereby reducing the volume of the indication circuit board 152, making the structure of the electric shaver 100 more compact and smaller. The protruding portion 1522 can be semicircular or have an arc-shaped outer peripheral wall, and correspondingly, the recessed portion 1222 is semicircular or has an arc-shaped inner peripheral wall. In addition, when the linear motor 120 works, it needs to drive the output shaft 121 to reciprocate in a preset direction, so the two ends of the linear motor 120 in the preset direction will swing up and down. By arranging the recessed portion 1222 on the motor frame 122 and spacing the outer peripheral wall of the protruding portion 1522 and the inner peripheral wall of the recessed portion 1222, the indication circuit board 152 will not interfere with the swing of the linear motor 120, avoiding the generation of noise due to abnormal sound.

[0173] In some embodiments, as shown in FIGS. 7, 8, 25-27, the electric shaver 100 further comprises a first flexible circuit board 191, one end of which is electrically connected with the main control board 151, and the other end thereof is electrically connected with the indication circuit board 152 around the power supply unit 140.

[0174] In the above embodiment, the first flexible circuit board 191 can be electrically connected with the main control board 151 and the indication circuit board 152 by welding, plug-in terminal plug-in and the like. In order to facilitate disassembly, the first flexible circuit board 191 can be electrically connected with the main control board 151 and the indication circuit board 152 by plug-in terminal plug-in, so that the first flexible circuit board 191 surrounds the power supply unit 140, which can shorten the wiring length and improve the convenience of wiring.

[0175] In some embodiments, as shown in FIGS. 7 and 8, the outer peripheral wall of the mounting bracket 130 is provided with an embedding groove 1305 extending in the circumferential direction around the power supply unit 140, and the first flexible circuit board 191 is at least partially embedded in the embedding groove 1305. In this way, the embedding groove 1305 can provide limiting installation for the first flexible circuit board 191, avoiding displacement of the first flexible circuit board 191, and also avoiding the flexible member protruding from the outer wall surface of the mounting bracket 130. Moreover, the embedding groove 1305 for installing the first flexible circuit board 191 is arranged on the outer peripheral wall of the mounting bracket 130, so that the mounting bracket 130 can insulate the first flexible circuit board 191 from the power supply unit 140, improving the operation stability of the whole machine.

[0176] In some embodiments, referring to FIGS. 7, 8, 25-27, the electric shaver 100 further comprises a key circuit board 153 fixed to the side wall of the mounting bracket 130 between the main control board 151 and the indication circuit board 152. The key circuit board 153 is provided with a key switch, and the shell 110 is provided with a key structure corresponding to the key switch.

[0177] In the above embodiment, the key circuit board 153 is used to realize the switching operation of the electric shaver 100. By arranging the key circuit board 153 on the side wall of the mounting bracket 130 between the main control board 151 and the indication circuit board 152, the main control board 151, the indication circuit board 152 and the key circuit board 153 are arranged on three sides of the motor 120, which not only ensures the compact structure but also divides the functions of the circuit boards and improves the convenience of product use.

[0178] In some embodiments, referring again to FIGS. 7, 8, 25-27, the electric shaver 100 further comprises a second flexible circuit board 192, one end of which is electrically connected to the key circuit board 153, and the other end is electrically connected to the main control board 151 or the indication circuit board 152, and the first flexible circuit board 191 and the second flexible circuit board 192 correspond to two power supply units 140 respectively.

[0179] Specifically, the second flexible circuit board 192 can be a wire, a flexible flat cable or the like. The second flexible circuit board 192 can be electrically connected to the key circuit board 153, the main control board 151 or the indication circuit board 152 by welding, plug-in terminal plug-in or the like. So that the first flexible circuit board 191 and the second flexible circuit board 192 correspond to the first power supply unit 140 and the second power supply unit 140 respectively, that is, the main control board 151 and the key circuit board 153 are electrically connected through the second flexible circuit board 192, and the main control board 151 and the indication circuit board 152 are electrically connected through the first flexible circuit board 191. In this way, the length of the wiring can be shortened, and the connection line can be simplified.

[0180] Optionally, the main control board 151, the indication circuit board 152 and the key circuit board 153 can be clamped and / or plugged and / or screwed to the mounting bracket 130. In this way, the main control board 151, the indication circuit board 152 and the key circuit board 153 can be detachably connected to the mounting bracket 130, which is more convenient for disassembly and maintenance of the circuit boards.

[0181] In some embodiments, as shown in FIGS. 30-32, the second conductive part 134 is taken as a conductive cylinder and the third conductive part 163 is taken as a conductive column. The stopper 1341 is protruded along the circumference of the conductive cylinder. The first conductive part 181 is partially clamped between the stopper 1341 and the mounting bracket 130. The wall surface of the mounting bracket 130 close to the charging bracket 510 is provided with an annular groove 13071 and an extension groove 13072 which are in communication with each other. The extension groove 13072 extends from the annular groove 13071 to the main control board 151. The stopper 1341 is embedded in the annular groove 13071. The first conductive part 181 is embedded in the annular groove 13071 and the extension groove 13072.

[0182] In the above embodiment, the conductive cylinder and the stopper 1341 can be integrally formed. The stopper 1341 can be an annular protrusion, a square protrusion or other shapes. In order to make the second conductive part 134 beautiful and simple, the stopper 1341 is generally annular. The stopper 1341 provides a limiting effect in the longitudinal direction to prevent the longitudinal movement of the conductive cylinder. The first conductive part 181 is partially clamped between the stopper 1341 and the base 1301 of the mounting bracket 130, effectively preventing the conductive part from loosening or shifting during use.

[0183] Further, the limiting part 1631 is protruded along the circumference of the conductive column. The second conductive part 182 is partially clamped between the bottom wall of the limiting part 1631 and the charging bracket 161. The wall surface of the charging bracket 161 close to the mounting bracket 130 is recessed to form a wiring groove 1612. The end of the conductive column close to the limiting part 1631 and the second conductive part 182 are both embedded in the wiring groove 1612.

[0184] In the above embodiment, the limiting part 1631 and the conductive column are integrally formed. A metal material with strong conductivity, such as copper or gold-plated copper, is used. The limiting part 1631 can be an annular protrusion which is protruded along the circumference of the conductive column to limit the longitudinal movement of the conductive column and provide clamping support for the second conductive part 182 to prevent displacement of the conductive column during plugging.

[0185] The limiting part 1631 is embedded in the wiring groove 1612, which helps to disperse the mechanical stress applied on the conductive column and reduces the risk of fracture of the conductive column due to excessive stress. The shape of the wiring groove 1612 can be the same as that of the limiting part 1631. Alternatively, the extension groove 13072 can be provided as a wiring channel for the second conductive part 182 to increase the contact area between the second conductive part 182 and the charging bracket 161, disperse the mechanical stress of the second conductive part 182 and prevent it from breaking.

[0186] In some embodiments, referring to FIGS. 30-33, the charging bracket 161 includes a main body portion 1613 and a transverse fixing portion 1614 protruding transversely from the main body portion 1613, the main body portion 1613 is at least partially embedded in the mounting bracket 130, and the charging circuit board 162 is connected to the top wall of the main body portion 1613. The third conductive portion 163 is installed on the transverse fixing portion 1614, the transverse fixing portion 1614 is spaced apart from the charging circuit board 162 in the longitudinal direction, and the transverse fixing portion 1614 is close to the bottom wall 112; the end of the main body portion 1613 away from the transverse fixing portion 1614 protrudes a connecting portion (not labeled in the figure), the transverse fixing portion 1614 and the connecting portion are provided with mounting holes, and the fasteners of the device are connected to the bottom wall 112 through the mounting holes, so that the charging bracket 161 is fixedly connected to the bottom wall 112. The provision of fasteners at both ends can balance the stress and prevent the charging bracket 161 from shaking, further improving the stability of the charging bracket 161 and the bottom wall 112.

[0187] In the above embodiments, the main body portion 1613 is used to support the charging circuit board 162, and the charging circuit board 162 is fixedly connected to the main body portion 1613 by threaded fasteners. The transverse fixing portion 1614 protrudes transversely from the main body portion 1613 and is used to fix the charging bracket 161 on the bottom wall 112 and provide a mounting platform for the third conductive portion 163. The transverse fixing portion 1614 can protrude from the main body portion 1613 in the first direction, and the main control board 151 is fixedly connected to the side wall of the mounting bracket 130 in the second direction, and the first direction and the second direction can be parallel or perpendicular. The end surface of the third conductive portion 163 away from the transverse fixing portion 1614 can be lower than the charging circuit board 162, or higher than or equal to the charging circuit board 162, in other words, the size of the third conductive portion 163 is not limited.

[0188] The transverse fixing portion 1614 is spaced apart from the charging circuit board 162 in the longitudinal direction, and the transverse fixing portion 1614 is close to the bottom wall 112, so that the top wall of the main body portion 1613 and the transverse fixing portion 1614 form a stepped shape, which helps to improve the compactness of the layout of the internal parts of the device.

[0189] In some embodiments, the third conductive part 163 is lower than the charging circuit board 162 away from the end surface of the transverse fixing part 1614. In this way, it helps to reduce the overall height of the device. For example, in the prior art, the electrical connector is usually in the same plane as the circuit board or directly mounted on the circuit board. Such a layout means that the thickness of the electrical connector is added to the thickness of the circuit board, thereby increasing the vertical height of the entire module. Since the stacking of various components within the device is usually arranged in the vertical direction, the height of the stacking directly leads to an increase in the overall thickness of the device. In the above-embodiment, the transverse fixing part 1614 separates the third conductive part 163 from the charging circuit board 162 and is mounted on the transverse fixing part 1614. In this way, the third conductive part 163 no longer occupies the vertical space on the charging circuit board 162, but is located lower than the charging circuit board 162. In this way, the structures that need to be stacked in the vertical direction are separated, unnecessary height stacking is avoided, and the height of the entire module is reduced.

[0190] Further, the transverse fixing part 1614 is protruded from the main body part 1613 in the first direction, and the main control board 151 is fixedly connected to the side wall of the mounting bracket 130 in the second direction (the first direction and the second direction are shown in FIG. 9).

[0191] In the above-embodiment, since the first direction is perpendicular to the second direction, that is, the protruding direction of the transverse fixing part 1614 and the fixing direction of the main control board 151 are perpendicular to each other, it means that the transverse fixing part 1614 and the main control board 151 are arranged in different directions and will not be stacked in the same direction, thereby reducing the size of the device in the width or length direction, which is beneficial to the miniaturization of the device.

[0192] In some embodiments, as shown in FIGS. 32 and 33, the bottom of the mounting bracket 130 is at least partially recessed to form an avoiding cavity 1308, and the transverse fixing part 1614 is embedded in the avoiding cavity 1308. The bottom wall of the avoiding cavity 1308 is provided with a through hole 133.

[0193] In the above-embodiment, by designing the avoiding cavity 1308 in the bottom of the mounting bracket 130, the transverse fixing part 1614 can be partially embedded in the avoiding cavity 1308, instead of being completely stacked outside the mounting bracket 130. This design reduces the space occupation in the vertical direction, while making full use of the internal space of the device, so that the layout inside the device is more compact, thereby reducing the overall height of the device and further reducing the volume of the device.

[0194] In some embodiments, the bottom wall 112 is provided with a protrusion 1121, and the bottom wall of the main body portion 1613 is provided with a sealing portion 1615 embedded in the protrusion 1121. The fixing protrusion 1611 is connected to the bottom wall of the transverse fixing portion 1614, the second conductive member 182 is at least partially embedded in the fixing protrusion 1611 and the transverse fixing portion 1614, and the third conductive portion 163 is embedded in the fixing protrusion 1611. The fixing protrusion 1611 is longitudinally spaced apart from the bottom wall 112.

[0195] In the above embodiments, the protrusion 1121 on the bottom wall 112 cooperates with the sealing portion 1615 protruding from the bottom wall of the main body portion 1613 to form an effective sealing structure. In some embodiments, a sealing ring can be sandwiched between the protrusion 1121 and the sealing portion 1615 to improve the sealing performance. In this way, dust, moisture or other impurities in the external environment can be prevented from entering the internal components of the device, thereby protecting the stable operation of the internal electronic components and prolonging the service life of the device.

[0196] Secondly, the transverse fixing portion 1614 can be fixedly connected to the protrusion 1121 by a threaded fastener, so that the fixing protrusion 1611 is longitudinally spaced apart from the bottom wall 112, ensuring the physical isolation between the third conductive portion 163 and the housing 110, thereby preventing the occurrence of electric leakage and significantly improving the safety of the device.

[0197] In addition, the second conductive member 182 is partially embedded in the fixing protrusion 1611 and the transverse fixing portion 1614, and the third conductive portion 163 is embedded in the fixing protrusion 1611. This embedded design not only saves space inside the device, but also ensures the close cooperation between the components, further reducing the overall volume of the device and facilitating the miniaturization of the device.

[0198] In some embodiments, the main body portion 1613 is formed with a receiving groove 1616, the charging circuit board 162 covers the top of the receiving groove 1616, and the charging female socket 164 is embedded in the receiving groove 1616 and fixedly connected to the charging circuit board 162.

[0199] In the above embodiments, the charging female socket 164 can be a type-C charging socket, a magnetic charging interface or a USB charging socket. The receiving groove 1616 is filled with sealing glue to improve the sealing performance of the charging module. By forming the receiving groove 1616 in the main body portion 1613, a receiving space is provided for the charging female socket 164, and the charging circuit board 162 covers the top of the receiving groove 1616 and is filled with sealing glue in the receiving groove 1616, so that the charging female socket 164 can be sealed in the receiving groove 1616, preventing dust, moisture and other impurities from entering the housing 110 through the charging female socket 164, thereby improving the service life of the electric shaver 100.

[0200] In some embodiments, referring to FIGS. 34-46, the motor frame 122 includes a frame body 1223 and a connecting lug 1224 protruding from a side wall of the frame body 1223. The first mounting base surface 171 corresponds to the connecting lug 1224, which is fitted to the first mounting base surface 171.

[0201] In the above embodiments, the frame body 1223 is used to accommodate the driving component 126 and the moving component 127, and the connecting lug 1224 is used to connect with other components to achieve the fixation of the entire motor frame 122. The first mounting base surface 171 provides a clear position reference point, ensuring that the motor frame 122 can be accurately placed at a predetermined position in the inner cavity of the housing 110. The fitting of the connecting lug 1224 to the first mounting base surface 171 makes it easier to align the device during assembly, ensuring the accuracy of the installation of the motor frame 122. At the same time, this close fitting can reduce the movement or loosening of the motor frame 122 during use due to vibration or load, improving the stability of the structure.

[0202] Further, the motor frame 122 includes two connecting lugs 1224 respectively provided on opposite side walls of the frame body 1223. The inner side of the end cover 170 protrudes two first stepped portions 177, which are arranged one-to-one with the two connecting lugs 1224. The side of the first stepped portion 177 facing the bottom wall 112 is the first mounting base surface 171. Since the two connecting lugs 1224 on the motor frame 122 are arranged one-to-one with the two first stepped portions 177 on the end cover 170, the first stepped portion 177 can accurately fit with the connecting lug 1224. In this way, the positioning stability of the end cover 170 on the motor frame 122 can be effectively improved, reducing the movement of the end cover 170 during use due to vibration or other factors.

[0203] Further, referring to FIG. 45, the two connecting lugs 1224 are respectively a first connecting lug 12241 and a second connecting lug 12242 that are different in shape. The two first stepped portions 177 are respectively provided with a mounting groove 1771 facing the inner cavity of the housing 110, and the shapes of the two mounting grooves 1771 are respectively adapted to the first connecting lug 12241 and the second connecting lug 12242. The bottom wall of the mounting groove 1771 is the first mounting base surface 171. The first connecting lug 12241 and the second connecting lug 12242 are respectively embedded in the corresponding mounting groove 1771.

[0204] At the same time, the mounting groove 1771 allows for some adjustment, which can ensure that when the first mounting base surface 171 is docked with the first connecting lug 12241 / second connecting lug 12242, even if there is a slight deviation, it can still be successfully installed and remain securely connected.

[0205] In the above embodiments, the first connecting lug 12241 and the second connecting lug 12242 with different shapes are respectively matched with the corresponding mounting groove 1771, which can ensure the correct assembly direction of the motor 120, reduce the assembly error of the motor 120, and improve the assembly efficiency of the motor 120 and the end cover 170.

[0206] In some embodiments, referring to FIGS. 36, 37, 41 and 45, the first mounting base surface 171 is provided with a first fixing hole 1711, and the connecting lug 1224 is provided with a first through hole 1221. The first fastener 300 passes through the first through hole 1221 and is fixed to the first fixing hole 1711.

[0207] In the above embodiments, the motor frame 122 and the end cover 170 are accurately positioned and aligned through the cooperation of the first fixing hole 1711 and the first through hole 1221. The connection is achieved by the first fastener 300. This connection method usually uses threads or other fastening mechanisms, which can effectively resist the influence of vibration and external force, and ensure that the connection will not loosen or fail. The first through hole 1221 is provided on the connecting lug 1224, which can not only achieve firm connection, but also ensure the structural strength of the motor frame 122.

[0208] In some embodiments, referring to FIGS. 41 and 44, the end cover 170 is provided with a motor accommodating groove 178 for accommodating a part of the motor 120. The bottom wall of the motor accommodating groove 178 is spaced apart from the first mounting base surface 171. The motor accommodating groove 178 can isolate the end cover 170 and the motor 120, to some extent, reducing the vibration of the motor 120 transmitted to the end cover 170. The bottom wall of the motor accommodating groove 178 is spaced apart from the first mounting base surface 171, which can provide a positioning reference for the installation of the motor 120.

[0209] In some embodiments, referring to FIGS. 35 and 45, the mounting bracket 130 is arranged on the periphery of the motor frame 122. In this way, the load distribution can be optimized, and the structural stability can be improved. Specifically, the mounting bracket 130 and the motor frame 122 are connected to different positions of the end cover 170, which can share and evenly distribute the bearing force, reducing the risk of deformation or damage of the end cover 170 under external impact or vibration. Meanwhile, the first mounting base surface 171 and the second mounting base surface 172 are spaced apart. They can be spaced apart in the center line direction of the installation opening 111, or can be spaced apart perpendicular to or close to perpendicular to the center line direction of the installation opening 111.

[0210] In some embodiments, referring to FIG. 46, the edge of the first mounting base surface 171 is connected with a fixing wall 179 extending towards the bottom wall 112. The outer side wall of the fixing wall 179 is the second mounting base surface 172. The bracket connecting plate 1306 is attached to the second mounting base surface 172.

[0211] In the above embodiment, the second mounting base surface 172 provides a clear position reference point, ensuring that the mounting bracket 130 can be accurately placed in the predetermined position. The bracket connecting plate 1306 fits against the second mounting base surface 172, making it easier to align the device during assembly, ensuring the accuracy of the installation of the mounting bracket 130. At the same time, this close fit can reduce the movement or loosening of the mounting bracket 130 during use due to vibration or load, improving the stability of the structure.

[0212] Further, the second mounting base surface 172 is provided with a second fixing hole 1721, and the axis of the second fixing hole 1721 and the second through hole 1303 are both perpendicular to the direction from the mounting opening 111 to the bottom wall 112. The third fastener 500 passes through the second through hole 1303 and is fixed to the second fixing hole 1721.

[0213] In the above embodiment, the bracket connecting plate 1306 and the fixed wall 179 are accurately positioned and aligned through the cooperation of the second fixing hole 1721 and the second through hole 1303. And the connection is realized by the third fastener 500. This connection method usually uses threads or other fastening mechanisms, which can effectively resist vibration and external forces, ensuring that the connection will not loosen or fail. The axis of the second fixing hole 1721 and the second through hole 1303 are both perpendicular to the direction from the mounting opening 111 to the bottom wall 112. This makes the installation more direct and simple, without the need for complex installation steps and tools, reducing the difficulty and cost of installation.

[0214] In some embodiments, referring to FIGS. 40 and 41, the second mounting base surface 172 is offset towards the bottom wall 112 relative to the first mounting base surface 171, and thereby forms a clearance space for accommodating the connecting lug 1224 and a portion of the first fastener 300. This helps to optimize the use of the internal space of the housing 110 and improve the structural compactness of the electric shaver 100.

[0215] Further, the inner side of the end cover 170 is provided with a second step portion 170a, and the side of the second step portion 170a towards the bottom wall 112 is the second mounting base surface 172. The side of the mounting bracket 130 towards the end cover 170 is provided with a third step portion 1309, and the third step portion 1309 fits against the second mounting base surface 172.

[0216] In the above embodiment, the second mounting base surface 172 provides a clear position reference point, ensuring that the mounting bracket 130 can be accurately placed in the predetermined position in the internal cavity of the housing 110. The third step portion 1309 fits against the second mounting base surface 172, making it easier to align the device during assembly, ensuring the accuracy of the installation of the mounting bracket 130. At the same time, this close fit can reduce the movement or loosening of the mounting bracket 130 during use due to vibration or load, improving the stability of the structure.

[0217] Meanwhile, the mounting bracket 130 in the above embodiment can be mounted to the end cover 170 along the centerline direction of the mounting opening 111. This mounting method can be more space-saving, as it allows the mounting bracket 130 to closely fit the inner side of the end cover 170, reducing the need for external space.

[0218] Further, the second mounting base surface 172 is provided with a third fixing hole 1722, and the mounting bracket 130 is provided with a third through hole 13091 that penetrates the side wall of the mounting bracket 130 close to the end cover 170 and the third stepped portion 1309. The axes of the third fixing hole 1722 and the third through hole 13091 are both parallel to the direction from the mounting opening 111 toward the bottom wall 112. The second fastener 400 passes through the third through hole 13091 and is fixed to the third fixing hole 1722.

[0219] In the above embodiment, the mounting bracket 130 and the end cover 170 are precisely positioned and aligned through the cooperation of the third fixing hole 1722 and the third through hole 13091. And the connection is achieved through the second fastener 400. This connection method usually uses threads or other fastening mechanisms, which can effectively resist the influence of vibration and external forces, ensuring that the connection will not loosen or fail. At the same time, the third stepped portion 1309 not only helps to provide a firm connection relationship, but also ensures the structural strength of the mounting bracket 130, avoiding the structural strength of the mounting bracket 130 from being reduced due to the third through hole 13091.

[0220] In some embodiments, referring to FIG. 41, the second stepped portion 170a is provided with a first avoiding slot 170b on the side surface facing the inner cavity of the housing 110. The bottom wall of the first avoiding slot 170b is the second mounting base surface 172. The third stepped portion 1309 is embedded in the first avoiding slot 170b. In this way, the space layout in the inner cavity of the housing 110 can be optimized, making the structure of the head assembly 200 of the electric shaver 100 compact, thereby facilitating the miniaturization of the electric shaver 100.

[0221] In some embodiments, the mounting bracket 130 is provided with a second avoiding slot 130a on the side surface facing the end cover 170; the second avoiding slot 130a accommodates the outer end of the first fastener 300. The second avoiding slot 130a not only makes the structure compact, but also compensates for assembly errors. In actual assembly, some assembly errors are inevitable, such as deviations caused by part manufacturing precision, operator skills, etc. The second avoiding slot 130a can compensate for the assembly error of the first fastener 300 to some extent, so that even if there is a slight deviation or misalignment, the assembly can still be completed, ensuring that the function and performance of the device are not affected.

[0222] In some embodiments, referring to FIG. 41, the lug 175 is provided with a fourth through hole 1751, and the shell 110 is provided with a fourth fixing hole 114 on the side wall surface facing the lug 175. The electric shaver 100 further comprises a fourth fastener 600, which is fixedly connected to the fourth fixing hole 114 through the fourth through hole 1751.

[0223] In the above embodiments, the shell 110 and the lug 175 are accurately positioned and aligned through the cooperation of the fourth fixing hole 114 and the fourth through hole 1751, and are connected through the fourth fastener 600. This connection method generally uses threads or other fastening mechanisms, which can effectively resist the influence of vibration and external forces, ensuring that the connection will not loosen or fail. At the same time, the shell 110 not only helps to provide a firm connection relationship, but also ensures the structural strength of the mounting bracket 130, avoiding the structural strength of the mounting bracket 130 from being reduced due to the fourth through hole 1751.

[0224] Further, the surface of the fourth fastener 600 away from the shell 110 is lower than or flush with the surface of the lug 175. If the surface of the fourth fastener 600 away from the shell 110 is higher than the surface of the lug 175, it will cause the surface of the lug 175 to be uneven, thereby affecting the precise assembly of the head assembly 200. The present embodiment places the fourth fastener 600 in the fourth through hole 1751 to ensure that the surface of the lug 175 is flat.

[0225] In some embodiments, referring to FIG. 41, the side surface of the lug 175 facing the shell 110 is a third mounting base surface 1752, and the side wall surface of the shell 110 facing the inner cavity of the shell 110 is provided with a fourth stepped portion 115, which is provided with a fourth fixing hole 114. The fourth stepped portion 115 is fixedly connected to the third mounting base surface 1752 facing the side surface of the lug 175.

[0226] In the above embodiments, the third mounting base surface 1752 provides a clear position reference point, ensuring that the shell 110 can be accurately placed in the predetermined position. The close fit of the fourth stepped portion 115 to the third mounting base surface 1752 makes it easier to align the device during assembly, ensuring the accuracy of the shell 110 installation. At the same time, this close fit can reduce the movement or loosening phenomenon of the shell 110 during use due to vibration or load, improving the stability of the structure.

[0227] Further, referring to FIGS. 36, 39-41, the side surface of the mounting bracket 130 facing the end cap 170 abuts against the third mounting base surface 1752, the second mounting base surface 172 is offset relative to the first mounting base surface 171 towards the bottom wall 112, and the third mounting base surface 1752 is offset relative to the second mounting base surface 172 towards the bottom wall 112.

[0228] In the above embodiments, the third mounting surface 1752 abuts against both the housing 110 and the mounting bracket 130. In this way, multi-point support can effectively disperse the lug 175 load and stress, reducing the stress concentration problem caused by single-point support, thereby facilitating the lug 175 to withstand vibration or external impact. Moreover, reusing the third mounting surface 1752 can reduce components, facilitating the electric shaver 100 to realize miniaturization and light weight. At the same time, the installation process can be simplified, and the accurate alignment of the motor bracket 122, the mounting bracket 130 and the housing 110 after assembly can be ensured, thereby reducing the risk of assembly errors and improving assembly efficiency.

[0229] In some embodiments, referring to FIGS. 42-45, the lug 175 further includes a fourth mounting surface 1753 on the side facing the bottom wall 112, the fourth mounting surface 1753 being spaced apart from the third mounting surface 1752, and the mounting bracket 130 is provided with a limiting protrusion 130b facing the lug 175, the limiting protrusion 130b abutting against the fourth mounting surface 1753.

[0230] In the above embodiments, the third mounting surface 1752 and the fourth mounting surface 1753 on the lug 175 abut against the housing 110 and the mounting bracket 130, respectively. In this way, multi-point support can effectively disperse the lug 175 load and stress, reducing the stress concentration problem caused by single-point support, thereby facilitating the lug 175 to withstand vibration or external impact. At the same time, the installation process can be simplified, and the accurate alignment of the motor bracket 122, the mounting bracket 130 and the housing 110 after assembly can be ensured, thereby reducing the risk of assembly errors and improving assembly efficiency. Moreover, the fourth mounting surface 1753 being spaced apart from the third mounting surface 1752 can effectively utilize the space inside the housing 110, improving structural compactness.

[0231] In some embodiments, as shown in FIG. 34, the side of the lug 175 facing away from the housing 110 is a first surface 81, the side of the end cover 170 facing away from the inner cavity of the housing 110 is a second surface 82, and the first surface 81 is offset toward the housing 110 from the second surface 82. The height difference between the first surface 81 and the second surface 82 can serve as a guide for assembly, ensuring that the head assembly 200 and the main machine of the electric shaver 100 are correctly assembled, thereby reducing assembly time and cost. At the same time, the height difference between the first surface 81 and the second surface 82 can also prevent the head assembly 200 from sliding and shifting. In addition, the height difference between the first surface 81 and the second surface 82 is also conducive to the optimization of the space inside the housing 110.

[0232] Further, as shown in FIG. 34, the first surface 81 is recessed towards the housing 110 to form a positioning recess 83, which is adapted to the joint surface of the head assembly 200. The planar positioning surface can only have one point or one line to position with the head assembly 200, which is easy to cause instability between the components due to slight deviation. The positioning recess 83 is curved, which can provide more positioning points, making it easier to achieve stable positioning during assembly.

[0233] In some embodiments, the inner wall surface of the housing 110 is limitedly matched with the periphery of the end cover 170. This ensures the accurate alignment of the housing 110 and the end cover 170 during assembly, avoids deviation or misalignment during assembly, and improves the assembly accuracy and stability. In addition, the side wall of the housing 110 is higher than or flush with the side of the end cover 170 away from the inner cavity of the housing 110. In this way, the side wall of the housing 110 can limit the deviation or sliding of the head assembly 200 relative to the housing 110, ensuring the normal operation of the electric shaver 100.

[0234] The above merely provides a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which shall be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
