[0052] The blades of a reciprocating shaver exert a certain impact force on the housing of the cutter head during the reciprocating motion. Therefore, noise is generated during the movement of the blades, which greatly affects the user experience.

[0053] In view of this, the utility model provides a reciprocating cutter head and a shaver. The shaver includes a reciprocating cutter head. The noise of the reciprocating cutter head is greatly reduced during operation, thereby improving the user experience.

[0054] Example 1:

[0055] See also Figures 1 to 3 The shaver provided by the present invention includes a main unit 100 and a reciprocating cutter head 200. The reciprocating cutter head 200 is detachably connected to the main unit 100. The main unit 100 is configured to drive at least a portion of the blade member 20 to reciprocate in a first direction X to shave hair. The detachable connection between the reciprocating cutter head 200 and the main unit 100 facilitates replacement or maintenance of the reciprocating cutter head 200 and facilitates cleaning of the cutter head.

[0056] See also Figure 1 and Figure 4 The reciprocating cutter head 200 includes a cutter head housing 10 and a blade member 20. The blade member 20 is detachably mounted in the cutter head housing 10. At least a portion of the blade member 20 can reciprocate along a first direction X.

[0057] By arranging the blade member 20 to be detachably mounted within the cutter head housing 10, the blade member 20 can be removed from the cutter head housing 10 and reassembled. Thus, when cleaning the reciprocating cutter head 200, the blade member 20 can be removed and cleaned separately, making the operation more convenient. At least a portion of the blade member 20 is arranged to reciprocate along the first direction X so that the blade member 20 can shave hair.

[0058] See also Figure 1 、 Figures 4 to 6 The reciprocating cutter head 200 further includes a buffer assembly 30, which is disposed between the blade member 20 and the cutter head housing 10 and is used to buffer the blade member 20 when at least a portion of the blade member 20 reciprocates along the first direction X.

[0059] By adopting the above technical solution and setting up a buffer assembly 30, when at least part of the blade assembly 20 reciprocates along the first direction X, the buffer assembly 30 plays a buffering role on the blade assembly 20, thereby avoiding the impact of the blade assembly 20 on the cutter head housing 10, and further avoiding the generation of noise, thereby greatly improving the user experience.

[0060] See also Figure 6 The blade member 20 includes a first end 21 and a second end 22 that are oppositely disposed along a first direction X. The buffer assembly 30 includes a first buffer member 31 and a second buffer member 32. The first buffer member 31 is disposed between the first end 21 of the blade member 20 and a side of the cutter head housing 10 that faces the first end 21, and is configured to buffer the blade member 20 when at least a portion of the blade member 20 moves toward the first end 21. The second buffer member 32 is disposed between the second end 22 of the blade member 20 and a side of the cutter head housing 10 that faces the second end 22, and is configured to buffer the blade member 20 when at least a portion of the blade member 20 moves toward the second end 22. In this way, when at least part of the blade component 20 moves toward the direction close to the first end 21, the first buffer member 31 buffers the blade component 20, preventing the first end 21 of the blade component 20 from impacting the cutter head housing 10, thereby avoiding the generation of noise; when at least part of the blade component 20 moves toward the direction close to the second end 22, the second buffer member 32 buffers the blade component 20, preventing the second end 22 of the blade component 20 from impacting the cutter head housing 10, thereby avoiding the generation of noise.

[0061] See also Figures 7 to 9The cutter head housing 10 is provided with a mounting slot 11, and the blade member 20 is detachably mounted in the mounting slot 11, and at least a portion of the blade member 20 can reciprocate in the mounting slot 11 along the first direction X. The mounting slot 11 is provided with a first buffer opening 12, a second buffer opening 13, and an inlet and outlet 14. The first buffer opening 12 and the second buffer opening 13 are arranged opposite to each other along the first direction X, and the inlet and outlet 14 is connected between the first buffer opening 12 and the second buffer opening 13.

[0062] The entrance 14 is configured to allow the blade member 20 to pass through and enter and exit the mounting slot 11. The first buffer opening 12 is configured to correspond to the first end 21 of the blade member 20 and to allow the first end 21 of the blade member 20 to pass through when at least a portion of the blade member 20 moves toward the first end 21. The second buffer opening 13 is configured to correspond to the second end 22 of the blade member 20 and to allow the second end 22 of the blade member 20 to pass through when at least a portion of the blade member 20 moves toward the second end 22. That is, when the blade member 20 is installed in the mounting slot 11, the first end 21 of the blade member 20 corresponds to the first buffer opening 12, and the second end 22 of the blade member 20 corresponds to the second buffer opening 13. When the blade member 20 reciprocates in the first direction X, the first end 21 of the blade member 20 can pass through the first buffer opening 12, and the second end 22 of the blade member 20 can pass through the second buffer opening 13. This configuration allows the blade member 20 to be removably mounted in the cutter head housing 10 and to reciprocate in the first direction X.

[0063] Because the first buffer member 31 is located between the first end 21 of the blade member 20 and the side of the cutter head housing 10 facing the first end 21, and the second buffer member 32 is located between the second end 22 of the blade member 20 and the side of the cutter head housing 10 facing the second end 22, when the blade member 20 passes through the first buffer opening 12, the first buffer member 31 provides a buffering effect on the first end 21 of the blade member 20, and when the blade member 20 passes through the second buffer opening 13, the second buffer member 32 provides a buffering effect on the second end 22 of the blade member 20. Therefore, the blade member 20 is prevented from impacting the cutter head housing 10.

[0064] See also Figure 6 、 Figure 8 and Figure 9The first buffer member 31 is a first buffer plate 311, and the second buffer member 32 is a second buffer plate 321. The first buffer plate 311 is connected to the side of the cutter head housing 10 facing the first end 21, and has a first gap 41 between it and the side of the cutter head housing 10 facing the first end 21. The second buffer plate 321 is connected to the side of the cutter head housing 10 facing the second end 22, and has a second gap 42 between it and the side of the cutter head housing 10 facing the second end 22. When the blade member 20 is installed in the cutter head housing 10, the first buffer plate 311 abuts against the first end 21 of the blade member 20, and the second buffer plate 321 abuts against the second end 22 of the blade member 20. In a specific implementation, the first buffer plate 311 can be tilted toward the direction close to the first buffer opening 12, and the second buffer plate 321 can be tilted toward the direction close to the second buffer opening 13.

[0065] When the blade member 20 is installed in the cutter head housing 10 , the first buffer plate 311 abuts the first end 21 of the blade member 20 , and the second buffer plate 321 abuts the second end 22 of the blade member 20 . This allows the blade member 20 to be clamped between the first buffer plate 311 and the second buffer plate 321 along the first direction X. When the blade member 20 reciprocates along the first direction X, it can move the first buffer plate 311 or the second buffer plate 321 without impacting the first buffer plate 311 or the second buffer plate 321 .

[0066] In a specific embodiment, when at least a portion of the blade member 20 moves toward the first end 21, the first end 21 of the blade member 20 drives the first buffer plate 311 to move, and a first gap 41 between the first buffer plate 311 and the side of the cutter head housing 10 facing the first end 21 can be reduced, thereby providing a buffering effect on the blade member 20 and preventing the blade member 20 from impacting the cutter head housing 10. When at least a portion of the blade member 20 moves toward the second end 22, the second end 22 of the blade member 20 drives the second buffer plate 321 to move, and a second gap 42 between the second buffer plate 321 and the side of the cutter head housing 10 facing the second end 22 can be reduced, thereby providing a buffering effect on the blade member 20 and preventing the blade member 20 from impacting the cutter head housing 10.

[0067] In one embodiment, the first buffer plate 311 and the second buffer plate 321 are integrally formed with the cutter head housing 10. This configuration reduces the number of steps required to assemble the first buffer plate 311 and the second buffer plate 321 with the cutter head housing 10, improving assembly efficiency and ensuring a secure connection between the first buffer plate 311 and the second buffer plate 321 and the cutter head housing 10.

[0068] In one embodiment, the first and second buffer plates 311, 321 are both made of plastic. Using plastic allows the first and second buffer plates 311, 321 to have a certain degree of elasticity, which facilitates the cushioning effect of the first and second buffer plates 311, 321. Of course, in specific applications, the first and second buffer plates 311, 321 can also be made of other elastic materials.

[0069] See also Figure 1 、 Figure 6 、 Figure 8 and Figure 9 The reciprocating cutter head 200 further includes a first clamping assembly 51 and a second clamping assembly 52. ​​The first clamping assembly 51 is connected between the first buffer plate 311 and the first end 21 of the blade member 20, and is used to clamp the first buffer plate 311 and the first end 21 of the blade member 20. The second clamping assembly 52 is connected between the second buffer plate 321 and the second end 22 of the blade member 20, and is used to clamp the second buffer plate 321 and the second end 22 of the blade member 20. Specifically, the first clamping assembly 51 and the second clamping assembly 52 are used to limit the blade member 20 in the depth direction of the mounting groove 11, preventing the blade member 20 from falling out of the mounting groove 11 through the entrance 14, thereby improving the firmness of the blade member 20 installed in the mounting groove 11.

[0070] See also Figure 6 and Figure 8 The first snap-fit ​​assembly 51 includes a first snap 511 and a first slot 512. The first snap 511 is arranged on the first buffer plate 311, and the first slot 512 is arranged on the first end 21 of the blade member 20. The blade member 20 is snap-fitted to the first buffer plate 311 through the snap-fitting of the first snap 511 and the first slot 512.

[0071] See also Figure 6 and Figure 9 The second clip assembly 52 includes a second clip 521 and a second clip groove 522. The second clip 521 is set on the second buffer plate 321, and the second clip groove 522 is set at the second end 22 of the blade component 20. The blade component 20 is clipped to the second buffer plate 321 through the clip-fitting of the second clip 521 and the second clip groove 522.

[0072] See also Figures 6 to 10The blade assembly 20 includes a first blade assembly 23, a second blade assembly 24, and a third blade assembly 25. The first blade assembly 23 and the second blade assembly 24 are detachably connected, and the third blade assembly 25 is movably connected between the first blade assembly 23 and the second blade assembly 24, capable of reciprocating relative to the first blade assembly 23 and the second blade assembly 24 in a first direction X. The first blade assembly 23 abuts against the first buffer plate 311 and the second buffer plate 321 at both ends, and is engaged with the first buffer plate 311 and the second buffer plate 321. This arrangement allows the first blade assembly 23, the second blade assembly 24, and the third blade assembly 25 to cooperate to achieve hair shaving. Furthermore, the first blade assembly 23, the second blade assembly 24, and the third blade assembly 25 can be separated from each other, facilitating maintenance and cleaning.

[0073] In a specific implementation, both ends of the first blade assembly 23 are disposed at the outermost ends of the blade member 20 in the first direction X. When the third blade assembly 25 reciprocates along the first direction X, an impact force is generated on the first blade assembly 23, causing the first blade assembly 23 to vibrate in the first direction X. By arranging the two ends of the first blade assembly 23 to abut against the first buffer plate 311 and the second buffer plate 321, respectively, the first buffer plate 311 and the second buffer plate 321 act as a buffer for the first blade assembly 23 when the first blade assembly 23 vibrates along the first direction X. That is, when at least a portion of the blade member 20 reciprocates along the first direction X, the first buffer plate 311 and the second buffer plate 321 act as a buffer for the blade member 20. In addition, by setting the two ends of the first blade assembly 23 to be respectively connected to the first buffer plate 311 and the second buffer plate 321, the first buffer plate 311 can be connected to the first end 21 of the blade component 20, and the second buffer plate 321 can be connected to the second end 22 of the blade component 20, thereby preventing the blade component 20 from detaching from the cutter head housing 10 from the entrance and exit.

[0074] See also Figure 1 、 Figure 6 、 Figure 7 and Figure 11 The reciprocating cutter head 200 further includes a swinging transmission member 60 disposed within the cutter head housing 10 and comprising a swinging rod 61 and a connecting rod 62 connected to the swinging rod 61. The swinging rod 61 and the connecting rod 62 both extend perpendicular to the first direction X and are disposed perpendicular to each other. The swinging rod 61 is configured to swing to drive at least a portion of the blade member 20 to reciprocate along the first direction X. Both ends of the connecting rod 62 are rotatably connected to the cutter head housing 10.

[0075] See also Figure 1 、 Figure 2 、 Figure 7 、 Figure 9 and Figure 11The swing lever 61 comprises a third end 611 and a fourth end 612 arranged oppositely, the third end 611 is provided with a receiving groove 613 with a notch facing away from the fourth end 612, and is used to drive connect the main machine 100 of the shaver, and the fourth end 612 is used to drive connect the blade member 20, so that at least part of the blade member 20 can reciprocate along the first direction X. In a specific implementation, the groove bottom of the mounting groove 11 is provided with a through hole 15 corresponding to the inlet and outlet 14, the fourth end 612 of the swing lever 61 penetrates through the through hole 15, and is drive connected to the third blade assembly 25. The main machine 100 drives the swing lever 61 to swing, and further drives the third blade assembly 25 to reciprocate along the first direction X.

[0076] By arranging the receiving groove 613 on the third end 611 of the swing lever 61, the driving device 101 of the main machine 100, i.e., the eccentric wheel 1012 described below, is movably connected in the receiving groove 613, so as to realize the drive connection between the swing lever 61 and the main machine 100. By arranging the notch of the receiving groove 613 to face away from the fourth end 612, the eccentric wheel 1012 of the main machine 100 is arranged in the receiving groove 613 through the notch of the receiving groove 613. In this way, the extension direction of the eccentric wheel 1012 is the same as the extension direction of the swing lever 61, and the extension direction of the driving component of the main machine 100 is perpendicular to the extension direction of the swing lever 61. The technical scheme has the advantages of more labor-saving and power-saving transmission.

[0077] Please refer to Figure 7 The head shell 10 is provided with two limiting holes 16 arranged oppositely, and the two ends of the connecting rod 62 are rotatably connected in the limiting holes 16. The connecting rod 62 is arranged perpendicularly to the swing lever 61, and is connected in a “cross” shape. In this way, on the one hand, the swing lever 61 can be rotatably connected to the head shell 10 through the connecting rod 62, and on the other hand, the swing lever 61 swings around the axial direction of the connecting rod 62 as the rotation center.

[0078] In an embodiment, the connecting rod 62 and the swing lever 61 are integrally formed. In this way, the assembly of the connecting rod 62 and the swing lever 61 can be reduced, and when the connecting rod 62 is installed in the head shell 10, the swing lever 61 can be installed in the head shell 10, so as to speed up the assembly efficiency.

[0079] Please refer to Figure 1 , Figures 5 to 7The cutter head housing 10 includes a first housing 17 and a second housing 18 connected to the first housing 17. The first housing 17 is used to connect to the main body 100. The blade member 20 is detachably mounted in the second housing 18. The buffer assembly 30 is disposed between the second housing 18 and the blade member 20. The first housing 17 and the second housing 18 together define a limiting hole 16, and a connecting rod 62 is connected between the first and second housings 17, 18. During assembly, the first and second housings 17, 18, and the connecting rod 62 can be pre-assembled and then fixedly connected using fasteners.

[0080] See also Figure 3 and Figure 6 The main unit 100 includes a driving device 101 and a main unit housing 102. The driving device 101 is arranged in the main unit housing 102. The driving device 101 includes a motor 1011 and an eccentric wheel 1012. The eccentric wheel 1012 is transmission-connected between the output shaft of the motor 1011 and the rocker arm 61. The motor 1011 drives the eccentric wheel 1012 to rotate eccentrically to drive the rocker arm 61 to swing.

[0081] See also Figure 5 and Figure 12 The cutter head housing 10 is provided with a plug-in protrusion 19, and the main body 100 is provided with a plug-in slot 1021 that plugs into the plug-in protrusion 19, and an access channel 1022 that connects to the plug-in slot 1021. The plug-in protrusion 19 is used to enter and exit the plug-in slot 1021 along the access channel 1022. The access channel 1022 has a 90° corner (not shown), and an inclined surface 1023 is provided within the access channel 1022, which is located at the 90° corner. Specifically, the main body housing 102 is provided with the plug-in slot 1021 and the access channel 1022, and the plug-in protrusion 19 is provided on the first housing 17.

[0082] In a specific implementation, when the reciprocating cutter head 200 is connected to the main unit 100, the cutter head housing 10 is moved along the access channel 1022 to the insertion slot 1021 and then rotated clockwise or counterclockwise to be inserted into the insertion slot 1021. When the reciprocating cutter head 200 is disconnected from the main unit 100, the cutter head housing 10 is rotated counterclockwise or clockwise to move out of the insertion slot 1021 and then out along the access channel 1022. The provision of the inclined surface 1023 at the 90° corner prevents the insertion protrusion 19 from being stuck in the 90° corner during movement through the access channel 1022, thereby facilitating smooth passage of the insertion protrusion 19 through the access channel 1022.

[0083] In one embodiment, see Figure 1 and Figure 2The reciprocating cutter head 200 further includes a protective cover 70 that is detachably connected to the cutter head housing 10 and covers the blade member 20. The protective cover 70 prevents people from accidentally touching the blade member 20 and getting cut. Of course, in other embodiments, the protective cover 70 may not be provided.

[0084] In one embodiment, see Figure 3 and Figure 13 The shaver further comprises a rotary cutter head 300, which is detachably connected to the main unit 100. The main unit 100 can be selectively connected to the reciprocating cutter head 200 or the rotary cutter head 300. In this way, the application range of the shaver can be expanded, and the user can choose to use different cutter heads according to different shaved parts.

[0085] See also Figure 13 The drive device 101 further includes a rotating transmission member 1013, which is connected between the output shaft of the motor 1011 and the eccentric wheel 1012. The rotary cutter head 300 is provided with an escape space 301, which is used to avoid the eccentric wheel 1012 so that the rotary cutter head 300 can be connected to the rotating transmission member 1013. This arrangement enables the motor 1011 to drive the rotary cutter head 300 to rotate. Specifically, the rotating transmission member 1013 is sleeved on the outer periphery of the output shaft of the motor 1011, and the eccentric wheel 1012 is connected to one end of the rotating transmission member 1013 and is integrally formed with the rotating transmission member 1013.

[0086] Example 2:

[0087] The main difference between the shaver provided in this embodiment and that in the first embodiment lies in the difference in the buffer assembly 30, which is specifically reflected in that: in the first embodiment, the first buffer member 31 is a first buffer plate 311, and the second buffer member 32 is a second buffer plate 321; while in this embodiment, the first buffer member 31 is a first buffer cotton 312, and the second buffer member 32 is a second buffer cotton 322.
