Detailed Implementation

[0012] To make the above-mentioned objectives, features, and advantages of this utility model more readily understood, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0013] like Figures 1-2 As shown, this utility model provides a parallel motion device for a double-headed shaver, characterized in that it includes: The cutter head 10 is provided with a double-blade assembly 20. The bottom of the double-blade assembly 20 is provided with a transmission assembly 30. The bottom of the transmission assembly 30 is provided with a parallel motion device 40. The parallel motion device 40 is connected to the eccentric shaft of a motor. The parallel motion device 40 is provided with a movable bracket 41, and a parallel bracket 42 is provided at the bottom of the movable bracket 41. The parallel bracket 42 is provided with positioning posts 420 at both ends and a hole 421 in the middle of the parallel bracket 42. The movable bracket 41 is provided with limiting grooves 410 at both ends, which can just accommodate the positioning posts 420, and the positioning posts 420 can move left and right in the limiting grooves. The movable bracket 41 is provided with a linkage mechanism 411 in the middle of the bottom. The linkage mechanism 411 is connected to the motor eccentric shaft, and the motor eccentric shaft can only rotate in the linkage mechanism 411. The movable bracket 41 is provided with a boss 412 in the middle of the end. The boss 412 is provided with a boss groove 413 for connecting the transmission assembly 30.

[0014] Specifically, the parallel motion device 40 is provided with a movable support 41, and a parallel support 42 is provided at the bottom of the movable support 41. Positioning posts 420 are provided at both ends of the parallel support 42, and limiting grooves 410 are provided at both ends of the movable support 41, which can precisely accommodate the positioning posts 420. The positioning posts 420 can only move horizontally and vertically within the limiting grooves. A hole 421 is provided in the middle of the parallel support 42, and a linkage mechanism 411 is provided in the middle of the bottom of the movable support 41. The linkage mechanism 411 passes through the hole 421 to connect to the motor eccentric shaft, and the motor eccentric shaft can only rotate within the linkage mechanism 411 and cannot disengage. A boss 412 is provided in the middle of the end of the movable support 41, and the boss 412 has a boss groove 413. A vibrating column 31 is provided at the bottom of the transmission assembly 30, which is wholly or partially embedded in the boss groove 413 and can only move up and down within the boss groove 413. The transmission assembly 30 has a short shaft vibrator 32 and a long shaft vibrator 33 on its end face. The double-blade assembly 20 has a short blade 21 and a high blade 22 respectively. The short shaft vibrator 32 is connected to the short blade 21, and the long shaft vibrator 33 is connected to the high blade 22. Therefore, when the parallel motion device 40 is working, it can drive the double-blade assembly 20 to perform reciprocating parallel motion.

[0015] Furthermore, when the shaver starts working, the rotation of the motor's eccentric shaft drives the linkage mechanism 411, which in turn drives the movable support 41 to reciprocate. Because the parallel support 42 has positioning posts 420 at both ends, and the movable support 41 has limiting grooves 410 at both ends, the positioning posts 420 can be fully or partially accommodated. Within the limiting grooves, the positioning posts 420 can only move horizontally and vertically without disengaging, thus enabling the parallel motion device 40 to achieve reciprocating parallel motion. This is further connected to the double-blade assembly 20 via the transmission component 30, thereby achieving parallel reciprocating movement and ensuring better cutting results.

[0016] In some embodiments, the bottom of the transmission component 30 is provided with a vibrating column 31, which is embedded in the boss groove 413 and can only move up and down within the boss groove 413. The end face of the transmission component 30 is provided with a short shaft vibrator 32 and a long shaft vibrator 33, which are connected to the double blade assembly 20.

[0017] Specifically, the bottom of the transmission assembly 30 is provided with a vibrating column 31, which is embedded in the boss groove 413 and can only move up and down within the boss groove 413 and cannot be disengaged. The end face of the transmission assembly 30 is provided with a short shaft vibrator 32 and a long shaft vibrator 33. The double blade assembly 20 is provided with a short blade 21 and a high blade 22 respectively. The short shaft vibrator 32 is connected to the short blade 21, and the long shaft vibrator 33 is connected to the high blade 22. Therefore, when the parallel motion device 40 is working, it can drive the double blade assembly 20 to perform reciprocating parallel motion.

[0018] In some embodiments, the dual-blade assembly 20 is provided with a short blade 21 and a tall blade 22, which cooperate with the transmission assembly 30.

[0019] Specifically, the dual-blade assembly 20 is provided with a short blade 21 and a tall blade 22 respectively, and the end face of the transmission assembly 30 is provided with a short shaft vibrator 32 and a long shaft vibrator 33. The short shaft vibrator 32 is connected to the short blade 21, and the long shaft vibrator 33 is connected to the tall blade 22. The transmission assembly 30 can drive the dual-blade assembly 20 to move.

[0020] In summary, the parallel motion device for a dual-headed shaver of this utility model includes: The cutter head 10 is equipped with a double-blade assembly 20. A transmission assembly 30 is located at the bottom of the double-blade assembly 20. A parallel motion device 40 is located at the bottom of the transmission assembly 30 and is connected to a motor eccentric shaft. The parallel motion device 40 is equipped with a movable bracket 41. A parallel bracket 42 is located at the bottom of the movable bracket 41. Positioning posts 420 are located at both ends of the parallel bracket 42. A hole 421 is located in the middle of the parallel bracket 42. Limiting grooves 410 are located at both ends of the movable bracket 41, which can accommodate the positioning posts 420, allowing the positioning posts 420 to move left and right within the limiting grooves. A linkage mechanism 411 is located at the middle of the bottom of the movable bracket 41, connecting to the motor eccentric shaft. The motor eccentric shaft can only rotate within the linkage mechanism 411. A boss 412 is located at the middle of the end of the movable bracket 41, with a boss groove 413 for connecting the transmission assembly 30. With the above design, the movable bracket 41 can only make horizontal reciprocating parallel movements, thereby driving the transmission component 30 to move, which in turn drives the double blade component 20 to make horizontal reciprocating parallel movements. This structural design is reasonable, ensuring the parallel movement of the blade head, thus resulting in better shaving effect and improving the user experience.
