[0041] The utility model provides an electric shaver.

[0042] In the embodiment of this utility model, please refer to Figures 1 to 9 The electric shaver 100 includes a housing 110 and a motor 130 installed in the housing 110, a mounting bracket 180 and two power supply units 140; the mounting bracket 180 is provided with a first accommodating cavity 181 and second accommodating cavities 182 located on both sides of the first accommodating cavity 181, the motor 130 is provided in the first accommodating cavity 181, and the two power supply units 140 are respectively provided in the two second accommodating cavities 182.

[0043] In this embodiment, the housing 110 provides installation and protection for the internal structure of the electric shaver 100, and the housing 110 can be made of metal, plastic, or other materials. The output shaft 120 of the motor 130 is connected to the cutter head assembly 200 of the electric shaver 100. Specifically, the output shaft 120 of the motor 130 is connected to the movable blade to drive the movable blade to move at high speed relative to the static blade to achieve shearing. There can be many structures of the cutter head assembly 200, and the cutter head assembly 200 includes at least one cutter head, each cutter head having a static blade and a movable blade, and the movable blade can move back and forth in a straight line along a preset direction relative to the static blade. The cutter head can be a long-beard cutter head or a short-beard cutter head, and can be selected and designed according to usage requirements, and is not specifically limited here.

[0044] The mounting bracket 180 is made of insulating material such as plastic to insulate the two power supply units 140. The two power supply units 140 are used to provide power to the entire electric shaver. The power supply units 140 are specifically batteries. The type of battery can be selected and designed according to actual needs and is not specifically limited here.

[0045] The electric shaver 100 of the present invention comprises a mounting bracket 180 with a first accommodating cavity 181 and second accommodating cavities 182 located on either side of the first accommodating cavity 181. The motor 130 is disposed within the first accommodating cavity 181, and two power supply units 140 are disposed within the two second accommodating cavities 182. This means that the power supply is disassembled into two power supply units 140, each disposed on either side of the motor 130. Compared to conventional shavers in which the motor 130 and battery are arranged in a "straight" configuration, this minimizes the length of the electric shaver while maintaining its thickness. Furthermore, the entire electric shaver 100 has a uniform distribution of gravity, resulting in a compact structure, small size, and minimal space occupation, making it more convenient for users to store and carry. Furthermore, the mounting bracket 180 provides mounting and protection for the two power supply units 140, preventing them from being accidentally damaged by collisions. The space between the two power supply units 140 on the mounting bracket 180 is fully utilized to mount the motor 130, making the overall structure even more compact.

[0046] In a specific embodiment, if Figures 8 to 12 As shown, the motor 130 is a linear motor 130 , and the two power supply units 140 are respectively located on both sides of the reciprocating motion direction of the linear motor 130 .

[0047] In this embodiment, the linear motor 130 can specifically be a magnetically levitated linear motor 130. In other embodiments, other types of linear motors 130 are also acceptable, as long as they can drive the output shaft 120 to achieve linear translational motion. The use of a linear motor 130 in an electric shaver provides high precision, fast response, high sensitivity, reliable operation, and a small weight and size, facilitating miniaturization of the electric shaver. The electric shaver 100 can utilize only one linear motor 130 to drive the movable blade, or it can utilize two linear motors 130, without specific limitation herein.

[0048] The linear motor 130 drives the movable blade to move back and forth in a straight line along a preset direction to achieve shearing relative to the static blade. For the sake of convenience, this article defines the reciprocating direction of the linear motor 130 as the width direction of the electric razor, and the axial direction of the output shaft 120 as the height direction of the electric razor. The thickness direction of the electric razor is then perpendicular to the width direction and the height direction of the electric razor. It is understandable that when the linear motor 130 is working, since it needs to drive the output shaft 120 to reciprocate along the preset direction, the linear motor 130 will have a slight up and down vibration at both ends of the preset direction. By arranging the two power supply units 140 on both sides of the reciprocating direction of the linear motor 130, it can act as a counterweight, so that the two power supply units 140 can balance and weaken the amplitude at both ends of the reciprocating direction of the linear motor 130, weaken the vibration of the entire electric razor, and improve the use effect of the product.

[0049] In one embodiment, please refer to Figure 4 、 Figure 5 and Figure 8 The shell 110 includes an outer shell 111 and an end cover 113. The outer shell 111 has an opening 112. The end cover 113 is connected to the opening 112. The motor 130, the mounting bracket 180 and the two power supply units 140 are all installed in the chamber surrounded by the outer shell 111 and the end cover 113, and the motor 130 and the mounting bracket 180 are respectively fixedly connected to the inner side of the end cover 113.

[0050] In this embodiment, the motor 130 and the mounting bracket 180 are both fixedly connected to the inner side of the end cap 113. During assembly, the motor 130 is first installed on the inner side of the end cap 113, and the power supply unit 140 is then installed in the second accommodating cavity 182 of the mounting bracket 180, so that the first accommodating cavity 181 of the mounting bracket 180 corresponds to the motor 130. The mounting bracket 180 is then fixedly connected to the end cap 113 to form a complete installation module. Finally, the entire installation module, including the end cap 113, mounting bracket 180, power supply unit 140, and motor 130, is installed into the inner cavity of the housing 111 through the opening 112, and the end cap 113 and housing 111 are fixedly connected to complete the assembly of the main body of the electric shaver 100. That is, this embodiment pre-assembles the mounting bracket 180, motor 130, and power supply unit 140 through the end cap 113, and the above-mentioned structure can be assembled modularly into the housing 111 as a whole, which can simplify installation and improve the efficiency of overall assembly.

[0051] Furthermore, if Figures 4 to 12 As shown, a first mounting base surface 114 is provided on the inner side of the end cover 113, a first accommodating cavity 181 has a first opening facing the end cover 113, and the motor 130 passes through the first opening to be fixedly connected to the first mounting base surface 114; the second accommodating cavity 182 has a second opening facing away from the end cover 113, and the power supply unit 140 is installed in the second accommodating cavity 182 through the second opening.

[0052] In this embodiment, the second accommodating cavity 182 has a second opening facing away from the end cover 113, and the two power supply units 140 are installed in the second accommodating cavity 182 from the bottom end, so that the mounting bracket 180 can be provided with a connecting structure on the top wall of the second accommodating cavity 182 to be connected and fixed to the end cover 113. It should be noted that if the motor 130 is directly mounted on the bracket, assembly errors are likely to occur, so that the output shaft 120 of the motor 130 cannot be accurately aligned with the connection seat of the cutter head, resulting in excessive noise. In this embodiment, the motor 130 is mounted on the first mounting base 114 of the end cover 113, which can provide a positioning reference for the motor 130, reduce assembly errors, and thus reduce noise.

[0053] Further, please refer again to Figures 4 to 12, the electric shaver 100 further includes a first fastener 300 and a second fastener 400;

[0054] The motor 130 includes a frame 131 , which is provided with a first through hole 134 . The first fastener 300 passes through the first through hole 134 and is connected to the first mounting base 114 to securely connect the motor 130 to the first mounting base 114 .

[0055] The end cover 113 is also provided with a second mounting base surface 115 corresponding to the bottom wall of the second accommodating cavity 182. The bottom wall of the second accommodating cavity 182 is provided with a second through hole 1821. The second fastener 400 passes through the second through hole 1821 and is connected to the second mounting base surface 115 to fix the mounting bracket 180 and the second mounting base surface 115.

[0056] In this embodiment, the first fastener 300 and the second fastener 400 may specifically be screws. The number of the first fastener 300 and the second fastener 400 may be one or more. Connecting the frame 131 of the motor 130 and the first mounting base 114 of the end cap 113 via the first fastener 300 ensures a secure and reliable connection between the two, while also facilitating assembly and disassembly for easy maintenance of the motor 130. Similarly, connecting the mounting bracket 180 and the second mounting base 115 of the end cap 113 via the second fastener 400 ensures a secure and reliable connection between the two, while also facilitating assembly and disassembly for easy maintenance of the motor 130.

[0057] like Figure 8 and Figure 9 As shown, in combination with the above embodiment in which the motor 130 and the mounting bracket 180 are respectively fixedly connected to the inner side of the end cover 113, the outer wall surface of the motor 130 is further spaced apart from the cavity wall of the first accommodating cavity 181. That is, the motor 130 is directly mounted on the end cover 113 of the housing 110, rather than on the mounting bracket 180. The outer wall surface of the motor 130 is spaced apart from the cavity wall of the first accommodating cavity 181, so that a shock-absorbing space can be formed between the outer wall surface of the motor 130 and the cavity wall of the first accommodating cavity 181, which can effectively prevent the vibration of the motor 130 from being transmitted to the mounting bracket 180.

[0058] In one embodiment, please refer to Figures 6 to 12 The mounting bracket 180 includes a connecting plate 185 and two battery mounting compartments 186 connected to both ends of the connecting plate 185 . The connecting plate 185 and the two battery mounting compartments 186 are arranged to form a first accommodating cavity 181 , and the battery mounting compartment 186 is provided with a second accommodating cavity 182 .

[0059] In this embodiment, to improve connection reliability, the connecting plate 185 is integrally formed with the two battery mounting compartments 186. The mounting bracket 180, through the two battery mounting compartments 186 and the connecting plate 185, forms the first and second accommodating chambers 181 and 182. This greatly simplifies the structure of the mounting bracket 180, making assembly of the electric shaver easier and improving overall assembly efficiency.

[0060] Furthermore, a hollowed-out clearance area is provided on the connecting plate 185. The end of the motor 130 facing away from the output terminal is positioned within the clearance area, and a gap is formed between the peripheral wall of the motor 130 and the inner wall of the clearance area. By positioning the end of the motor 130 facing away from the output terminal within the clearance area, the stacking height of the electric shaver can be reduced, making the overall structure of the electric shaver more compact and more compact.

[0061] In one embodiment, if Figure 6 、 Figure 7 、 Figure 10 、 Figure 12 As shown, the mounting bracket 180 also has a first side window 187 located between the two second accommodating cavities 182. The electric shaver also includes a first circuit board 150 arranged in the shell 110. The first circuit board 150 is installed on the side of the mounting bracket 180 where the first side window 187 is provided. The first circuit board 150 has a avoidance notch 153 corresponding to the first side window 187. The motor 130 is exposed to the first circuit board 150 through the first side window 187 and the avoidance notch 153.

[0062] In practice, the mounting bracket 180 has two opposing first and second side windows 187 and 188. The first circuit board 150 can specifically be the main control board of the electric shaver 100. Mounting the first circuit board 150 on the side of the mounting bracket 180 where the first side window 187 is located creates a compact structure, allowing the first circuit board 150 to be positioned between the two power supply units 140 and facing the motor 130, effectively shortening wiring lengths. It is understood that the first circuit board 150 is disposed on one side of the motor 130 in the thickness direction of the shaver, such that the first circuit board 150 has a clearance notch 153 corresponding to the first side window 187. The motor 130 is exposed on the first circuit board 150 through the first side window 187 and the clearance notch 153. In other words, the first circuit board 150 is arranged in an enclosing or semi-enclosing structure, surrounding the outer periphery of the motor 130 within the plane of its board surface. In this way, the first circuit board 150 does not occupy any dimension of the electric shaver 100 in the thickness direction, so that the thickness of the entire electric shaver is the thickness of the motor 130. Minimizing the thickness of the motor 130 shaver can make the thickness of the electric shaver extremely thin, greatly reducing the size of the entire device, and making it more convenient for users to store and carry. Specifically, the first circuit board 150 and the outer wall surface of the frame 131 are arranged side by side on the board surface of the first circuit board 150.

[0063] Furthermore, the first circuit board 150 includes two first sections 151 corresponding to the two second accommodating cavities 182, and a second section 152 connected to the two first sections 151. The second section 152 is located on the side of the motor 130 facing away from the output end, that is, the second section 152 is arranged corresponding to the connecting plate 185. In this way, the first circuit board 150 has a roughly U-shaped semi-enclosed structure, which is more convenient to manufacture and install.

[0064] In one embodiment, please refer to Figure 4 、 Figure 11 and Figure 12 The electric shaver 100 also includes a second circuit board 160, which is arranged on the side opposite to the side wall of the mounting bracket 180 where the first side window 187 is provided, that is, the first circuit board 150 and the second circuit board 160 are arranged on opposite sides of the mounting bracket 180; an indicator light is provided on the second circuit board 160, and a light-transmitting hole is provided on the housing 110 corresponding to the indicator light.

[0065] In this embodiment, the second circuit board 160 is specifically an indicator light circuit board. By having the first circuit board 150 and the second circuit board 160 separately disposed at the first side window 187 and the second side window 188 of the mounting bracket 180, a single circuit board can be adapted to the size of the motor 130, thereby preventing a single circuit board from exceeding the motor 130 and increasing the size of the entire electric shaver 100. Furthermore, the first circuit board 150, the second circuit board 160, and the two power supply units 140 are arranged around the motor 130, making full use of the space around the motor 130, making the overall structure more compact, and further miniaturizing the entire machine. In addition, by having the first circuit board 150, the second circuit board 160, and the two power supply units 140 all mounted on the mounting bracket 180, modular assembly of the entire machine can be achieved, simplifying installation and helping to improve the assembly efficiency of the entire machine.

[0066] Specifically, if Figure 6 、 Figure 10 、 Figure 11 As shown, fixing grooves 183 are recessed on opposite side walls of the mounting bracket 180, and the first circuit board 150 and the second circuit board 160 are respectively mounted in the fixing grooves 183. By providing the fixing grooves 183 on the opposite side walls of the mounting bracket 180 to mount the first circuit board 150 and the second circuit board 160, the first circuit board 150 and the second circuit board 160 do not protrude from the wall surface of the mounting bracket 180 after being secured to the mounting bracket 180. This protects the first circuit board 150 and the second circuit board 160 while reducing the thickness of the electric shaver 100. The first circuit board 150 and the second circuit board 160 can be fixed in the fixing grooves 183 by means of snap-fitting, plugging, screw connection, or the like.

[0067] Furthermore, if Figure 11 and Figure 12 As shown, the second circuit board 160 is arranged on the side of the frame 131 of the motor 130 away from its output end; the second circuit board 160 includes a main body 161 and a protrusion 162 arranged on the peripheral wall of the main body 161, and indicator lights are provided on the main body 161 and the protrusion 162. The frame 131 is provided with a recessed portion 132 corresponding to the protrusion 162, and the outer peripheral wall of the protrusion 162 is spaced apart from the inner peripheral wall of the recessed portion 132.

[0068] In order to meet the different indication functions of the electric shaver, it is necessary to provide two or more indicator lights spaced apart. In this embodiment, the second circuit board 160 includes a main body 161 and a protrusion 162 provided on the peripheral wall of the main body 161. Indicator lights are provided on both the main body 161 and the protrusion 162. This arrangement can not only form two or more indicator lights, but also minimize the volume of the main body 162, thereby reducing the volume of the second circuit board 160, making the structure of the electric shaver 100 more compact and smaller. Among them, the protrusion 162 can be semicircular or have an arc-shaped outer peripheral wall. Correspondingly, the recessed portion 132 can also be semicircular or have an arc-shaped inner peripheral wall. In addition, when the linear motor 130 is in operation, since it needs to drive the output shaft 120 to reciprocate in a preset direction, the linear motor 130 will swing up and down at both ends in the preset direction. By providing the recessed portion 132 on the frame 131 and spacing the outer peripheral wall of the protrusion 162 from the inner peripheral wall of the recessed portion 132 , the second circuit board 160 will not interfere with the deflection of the linear motor 130 , thereby avoiding abnormal sounds and generating noise.

[0069] In one embodiment, if Figures 8 to 12 As shown, the electric shaver 100 further includes a first flexible circuit board 191 , one end of which is electrically connected to the first circuit board 150 , and the other end of which surrounds a power supply unit 140 and is electrically connected to the second circuit board 160 .

[0075] In this embodiment, the second flexible circuit board 192 may be a wire, a flexible flat cable, or the like. The second flexible circuit board 192 can be electrically connected to the third circuit board 170, the first circuit board 150, or the second circuit board 160 via welding, plug-in terminals, or other methods. 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 first circuit board 150 and the third circuit board 170 are electrically connected via the second flexible circuit board 192, and the first circuit board 150 and the second circuit board 160 are electrically connected via the first flexible circuit board 191. This shortens wiring length and simplifies connection lines.

[0076] Specifically, the first circuit board 150, the second circuit board 160, and the third circuit board 170 are snap-fitted and / or plug-fitted and / or screw-connected to the mounting bracket 180. In this way, the first circuit board 150, the second circuit board 160, and the third circuit board 170 are detachably connected to the mounting bracket 180, making it easier to disassemble and repair the circuit boards.
