[0039] The present application provides an electric shaver 100.

[0040] In the embodiments of the present application, please refer to Figures 1 to 8 The electric shaver 100 includes a main machine 200, a short beard cutter head 300 and a long beard cutter head 400; wherein the short beard cutter head 300 and the long beard cutter head 400 are alternatively and detachably installed on the top of the main machine 200; the short beard cutter head 300 includes a first moving cutter 310 and a static cutter net 320 covering the first moving cutter 310, the static cutter net 320 is provided with a plurality of entry holes (not marked in the figure), and the first moving cutter 310 reciprocates along a preset direction relative to the static cutter net 320 to shear hair; the long beard cutter head 400 includes a second moving cutter 410 and a static cutter blade 420 covering the second moving cutter 410, the static cutter blade 420 includes a plurality of intervally arranged shearing teeth 421, and adjacent two shearing teeth 421 form an entry space (not marked in the figure), and the second moving cutter 410 reciprocates along a preset direction relative to the static cutter blade 420 to shear hair.

[0041] In the embodiment, the host 200 is the core part of the entire electric shaver 100, and generally includes driving and power supply components such as a motor and a battery. It is responsible for providing power for the cutter head, enabling the moving cutter to perform reciprocating motion to complete the shearing action. The short beard cutter head 300 is a cutter head for shearing short-length beard, including a first moving cutter 310 and a static cutter net 320. The static cutter net 320 is a mesh structure covering the first moving cutter 310, has a plurality of entry holes allowing beard to enter, and prevents the skin from contacting the moving cutter, thereby ensuring safety. The host 200 controls the first moving cutter 310 to reciprocate along a predetermined direction to shear the beard entering through the static cutter net 320. The shape of the static cutter net 320 can be arc-shaped or other shapes, to more closely fit the curvature of the mandibular angle, so that the shearing is more complete. Generally, the static cutter net 320 is arc-shaped. The shape of the first moving cutter 310 is generally adapted to the shape of the static cutter net 320 to more closely fit the static cutter net 320, thereby improving the shearing efficiency.

[0042] The long beard cutter head 400 is used for shearing long beard, and includes a second moving cutter 410 and a static cutter blade 420. The static cutter blade 420 is plate-shaped, and the shearing teeth 421 are located at the edge position of the static cutter blade 420. Adjacent two shearing teeth 421 form an entry space for guiding long beard to enter the shearing area of the moving cutter. The host 200 controls the second moving cutter 410 to reciprocate along a predetermined direction to shear the beard entering through the entry space.

[0043] It can be understood that the long beard cutter head 400 and the short beard cutter head 300 are detachably connected with the host 200. The long beard cutter head 400 and the short beard cutter head 300 can be connected with the host 200 through snap connection, threaded connection, plug-in connection, magnetic attraction connection or other detachable connection modes. In order to make the overall structure of the machine more simple, the long beard cutter head 400 and the short beard cutter head 300 are generally provided with the same detachable connection mode with the host 200, for example, the long beard cutter head 400 is magnetically attracted to the host 200, and the short beard cutter head 300 is also magnetically attracted to the host 200.

[0044] The host 200 is connected with one cutter head at a time, and the short beard cutter head 300 and the long beard cutter head 400 are detachably installed on the top of the host 200, and can be interchanged between them. In other words, the user can select to install the appropriate short beard cutter head 300 or long beard cutter head 400 according to the length of the beard. The utility model detachably connects the short beard cutter head 300 and the long beard cutter head 400 with the host 200, so that the user can freely select different cutter heads according to the length of the beard. In this way, compared with the existing single cutter head with only one cutter head, the utility model can be applied to different beard lengths, and is more functional. Compared with the multi-cutter shaver, the structure of the utility model is relatively simple, only one cutter head is connected at a time, so that the volume and weight are relatively light, and the portability of the product is improved.

[0045] In an embodiment, referring to Figures 2 to 4 The host 200 further comprises a transmission shaft 210, which is detachably connected with the first moving cutter 310 or the second moving cutter 410 and located at the middle of the first moving cutter 310 or the second moving cutter 410 in the preset direction; the short-hair cutter head 300 or the long-hair cutter head 400 is magnetically connected with the host 200 on the opposite sides of the transmission shaft 210 in the preset direction.

[0046] In the embodiment, the transmission shaft 210 is connected with the first moving cutter 310 or the second moving cutter 410 to transmit the power generated by the motor in the host 200 to the moving cutter on the cutter head, so that the moving cutter moves reciprocatingly along the preset direction to realize the function of shearing hair. The transmission shaft 210 is located at the middle of the cutter head, and the power can be uniformly transmitted to the moving cutter to reduce the force difference on the left and right sides of the cutter head, so as to ensure that the moving cutter can keep stable reciprocating motion during work and improve the shaving efficiency and shearing effect.

[0047] Secondly, the short-hair cutter head 300 or the long-hair cutter head 400 is connected with the host 200 by magnetic attraction, and the magnetic force enables the cutter head to be firmly attracted to the host 200, while facilitating the user to detach and replace the cutter head. Compared with the traditional buckle or threaded connection mode, the magnetic attraction connection simplifies the operation steps and improves the user experience. The position of the magnetic attraction connection is located on the two sides of the transmission shaft 210, which enhances the stability of the connection and balances the stress of each component.

[0048] In addition, since the short-hair cutter head 300 and the long-hair cutter head 400 are magnetically connected with the host 200, and the transmission shaft 210 is detachably connected with the moving cutter, it means that during the process of replacing the cutter head by the user, the cutter head and the transmission shaft 210 will be separated at the same time when the user separates the cutter head from the host 200 by a simple plug-in action, which is conducive to improving the replacement efficiency and replacing the long-hair cutter head 400 or the short-hair cutter head 300 without other tools.

[0049] It should be noted that in some embodiments, one of the short-hair cutter head 300 and the host 200 can be a magnet, and the other can be an iron sheet; one of the long-hair cutter head 400 and the host 200 can be a magnet, and the other can be an iron sheet; the magnetic attraction materials of the long-hair cutter head 400 and the short-hair cutter head 300 are the same; in other embodiments, the long-hair cutter head 400, the short-hair cutter head 300 and the host 200 can all be magnets, which are not limited herein.

[0050] Further, the end of the transmission shaft 210 close to the first moving cutter 310 or the second moving cutter 410 is provided with a buffer portion 220, and the first moving cutter 310 or the second moving cutter 410 is provided with a groove 311 corresponding to the buffer portion 220, and the buffer portion 220 is embedded in the groove 311

[0051] In the embodiment, the material of the buffer portion 220 can be plastic, silica gel, rubber, etc., the material of the transmission shaft 210 can be stainless steel, aluminum alloy, etc., and the hardness of the buffer portion 220 is smaller than that of the transmission shaft 210. The buffer portion 220 is installed at one end of the transmission shaft 210 close to the tool bit, so as to play a buffering role in the transmission process, reduce vibration, noise and friction in the transmission process. The first moving cutter 310 or the second moving cutter 410 is provided with a groove 311 matched with the buffer portion 220, so that the transmission shaft 210 can be embedded in the groove 311, thereby providing a positioning effect for the connection of the tool bit and the main machine 200, and ensuring that the transmission shaft 210 can reduce vibration and noise in all directions when driving the first moving cutter 310 or the second moving cutter 410 to move.

[0052] In an embodiment, the main machine 200 is provided with a first magnetic member 230 on the opposite sides of the transmission shaft 210 along a preset direction, the short whisker tool bit 300 is provided with a second magnetic member 330 corresponding to the first magnetic member 230, the long whisker tool bit 400 is provided with a third magnetic member 440 corresponding to the first magnetic member 230, and the second magnetic member 330 or the third magnetic member 440 is respectively magnetically attracted to the first magnetic member 230, so as to magnetically attract and connect the long whisker tool bit 400 or the short whisker tool bit 300 to the main machine 200.

[0053] In the embodiment, the second magnetic member 330, the third magnetic member 440 and the first magnetic member 230 are all magnets, and the shapes of the three are the same, which can be rectangular, circular or other shapes. Compared with the connection mode of a magnet and an iron sheet, the magnetic attraction between magnets is stronger, which ensures that the tool bit will not easily fall off during use. Secondly, the first magnetic member 230 is arranged on the opposite sides of the transmission shaft 210, and the second magnetic member 330 corresponding to the first magnetic member 230 is also arranged on the opposite sides of the transmission shaft 210 of the short whisker tool bit 300, and the third magnetic member 440 corresponding to the first magnetic member 230 is also arranged on the opposite sides of the transmission shaft 210 of the long whisker tool bit, so as to make the connection of the short whisker tool bit 300 or the long whisker tool bit 400 to the main machine more stable, and the symmetrical structure of the magnetic members can balance the stress.

[0054] In an embodiment, the host 200 comprises a handle shell 240 and a top cover 250 detachably connected to the top of the handle shell 240, and the top cover 250 protrudes from the top of the handle shell 240, the third installation slot 251 is opened on the wall surface of the top cover 250 away from the long whisk blade head 400 or the short whisk blade head 300, and the first magnetic member 230 is installed in the third installation slot 251; the short whisk blade head 300 further comprises a first shell 340 and a first base 343, the first shell 340 surrounds the static blade net 320, and at least part of the static blade net 320 is exposed from the first shell 340, the bottom of the first shell 340 abuts against the top of the handle shell 240, and the inner wall surface of the first shell 340 abuts against the outer side wall of the top cover 250, the first base 343 is arranged in the first shell 340, the first installation slot 341 is opened in the wall surface of the first base 343 away from the host 200, and the second magnetic member 330 is fixedly installed in the first installation slot 341; the long whisk blade head 400 further comprises a second shell 450 and a second base 452, the second shell 450 covers both ends of the static blade 420, the bottom of the second shell 450 abuts against the top of the handle shell 240, and the inner wall surface of the second shell 450 abuts against the outer side wall of the top cover 250, the second base 452 is arranged in the second shell 450, the second installation slot 451 is opened in the wall surface of the second base 452 away from the host 200, and the third magnetic member 440 is fixedly installed in the second installation slot 451.

[0055] In the embodiment, each magnetic member can be fixedly connected in the installation slot by means of bonding, buckling, screwing or the like, the first magnetic member 230 is arranged on the side of the top cover 250 away from the blade head, that is, the first magnetic member 230 is arranged on the inner side of the top cover 250, physical isolation is provided between the first magnetic member 230 and the second magnetic member 330 or the third magnetic member 440, so that the first magnetic member 230 is prevented from being attracted away from the host 200 by the second magnetic member 330 or the third magnetic member 440. The positions of the first installation slot 341 and the second installation slot 451 are also arranged to prevent the first magnetic member 230 or the third magnetic member 440 from being attracted away from the blade head, which will not be described herein again. The first shell 340 can be made of durable plastic or metal, the first base 343 is arranged in the first shell 340 and located on the lower side of the moving blade, for providing a mounting platform for each component. The top cover 250 protrudes from the top of the handle shell 240, the bottom of the first shell 340 abuts against the top of the handle shell 240, and the inner wall surface of the first shell 340 abuts against the outer side wall of the top cover 250, which means that the top cover 250 is embedded in the first shell 340, that is, the first shell 340 provides a limiting action for the top cover 250, thereby enhancing the connection strength between the host 200 and the short whisk blade head 300. The second magnetic member 330 is arranged on the side of the first base 343 away from the host 200, so that the second magnetic member 330 is prevented from being attracted away from the short whisk blade head 300.

[0062] Secondly, the third magnetic member 440 is arranged away from the metal fastener 470 in a preset direction, which can effectively avoid the interference of the metal fastener 470 on the magnetic member, ensure the magnetic attraction connection stability of the third magnetic member 440 and the first magnetic member 230, and avoid the influence of the metal cantilever 360 on the magnetic attraction force between the long-hair cutter head 400 and the main machine 200.

[0063] In an embodiment, referring to Figure 5 and Figure 6 The short-hair cutter head 300 further includes a limiting holder 370 and a buffer member 380 connected to each other, the limiting holder 370 encloses the first static cutter holder 350, the limiting holder 370 is fixed in the first housing 340 and located on the side of the first base 343 facing the first static cutter holder 350, the buffer member 380 is clamped between the limiting holder 370 and the first base 343, the buffer member 380 has a limiting surface 381 facing the first base 343, the limiting surface 381 and the first base 343 are arranged in a longitudinal direction, the first static cutter holder 350 is provided with a limiting lug 390 in a transverse direction, the limiting lug 390 is located between the limiting surface 381 and the first base 343, and the limiting lug 390 is limitedly matched with the limiting surface 381.

[0064] In the embodiment, the limiting frame 370 is annular, and is arranged on the outer circumferential surface of the first static blade frame 350. The limiting frame 370 is used in cooperation with the limiting lug 390 to limit the floating range of the first static blade frame 350 in the longitudinal direction. For example, the first static blade frame 350 is floatingly mounted on the first base 343 in the longitudinal direction, and the limiting frame 370 forms a limiting space with the wall surface of the first base 343 to limit the floating range of the first static blade frame 350. Since the static blade net 320 is fixedly connected with the first static blade frame 350, and the first moving blade 310 is attached to the static blade net 320, the floating range of the first static blade frame 350 is limited, and the floating range of the static blade net 320 and the first moving blade 310 is also limited.

[0065] In order to reduce the noise generated when the limiting lug 390 collides with the limiting frame 370, the buffer 380 is arranged on the wall surface of the limiting frame 370 facing the first base 343 to absorb the mechanical vibration of the two. The material of the buffer 380 can be foam, rubber or other materials with buffering effect, and the shape can be long strip shape.

[0066] In an embodiment, the wall surface of the first base 343 facing the limiting surface 381 is provided with a supporting portion 344, the limiting frame 370 includes an annular main body portion 371 and a protruding portion 372, the annular main body portion 371 surrounds the first static blade frame 350, the buffer 380 extends along a predetermined direction and is clamped between the annular main body portion 371 and the supporting portion 344, the protruding portion 372 extends from the annular main body portion 371 to the first base 343, the protruding portion 372 abuts against the first base 343, and the supporting portion 344 is located on the inner side of the protruding portion 372.

[0067] In the embodiment, the supporting portion 344 is a protrusion on the first base 343 and is integrally formed with the first base 343. The material of the supporting portion 344 can be the same as that of the first base 343, which is used to support the buffer 380 and prevent the buffer 380 from falling off the limiting frame 370.

[0068] The protruding portion 372 extends from the annular main body portion 371 and abuts against the first base 343, which plays a supporting role and further enhances the connection stability of the limiting frame 370 and the first base 343, avoiding the limiting frame 370 from being suspended and easily shaking. The supporting portion 344 clamps the buffer 380 together with the annular main body portion 371, which means that the supporting portion 344 also has a supporting effect on the annular main body portion 371. The double supporting effects ensure the stability of the annular main body portion 371 to better limit the static blade net 320 and the first moving blade 310. In addition, the supporting portion 344 is located on the inner side of the protruding portion 372 to limit the limiting frame 370 in the transverse direction, preventing the limiting frame 370 from moving in the transverse direction during work, thereby ensuring the stability of the blade head.

[0069] In an embodiment, the wall surface of the first base 343 facing the limiting surface 381 corresponds to the limiting lug 390 and is provided with a protrusion 345, the buffer 380 is longitudinally spaced apart from the protrusion 345, and the limiting lug 390 is located between the protrusion 345 and the buffer 380.

[0070] In the embodiment, the protrusion 345 is integrally formed with the first base 343, and the protrusion 345 cooperates with the buffer 380 to limit the floating range of the first static cutter holder 350, so as to avoid that the floating range is too large. By adjusting the height of the protrusion 345, the floating range can be adjusted, so as to improve the stability of the first static cutter holder 350. In addition, the protrusion 345 can also be used as a stress concentration position. When the shaver is working, the static cutter net 320 and the first dynamic cutter 310 will be subjected to forces from different directions of the beard and the skin. These forces are transmitted to the first base 343 through the limiting lug 390. The protrusion 345 as a protruding local structure bears part of the stress concentration, and then disperses the stress to other positions of the first base 343, so as to play a buffering role and avoid deformation or fatigue damage of the first base 343.
