The other end of the rotating cylinder 2 is axially installed in the second side 26. At the same time, one end of the rotating cylinder 2 is axially installed in the first side 25 along with the axial sleeve movement. When the rotating cylinder 2 is removed, the gear transmission structure remains in the second side 26. The rotating cylinder 2 is axially removed in the opposite direction of the axial sleeve.

This design is conducive to compact structure.

[0042] In this example, the input end is connected with the gear transmission structure, the input end is used to drive the gear transmission structure to rotate, the gear transmission structure is used to drive the rotating cylinder 2 to rotate, and the gear transmission structure is used to drive the reciprocating motion structure to reciprocate.

Such design is conducive to more compact structure and more effective control of the volume of the whole structure.

[0047] As shown in Figure 7 , after the cut hair roller brush is installed between the first side 25 and the second side 26, the fixed part 4, the gear transmission structure, and the reciprocating motion structure are sequentially arranged along the rotating cylinder 2 from right to left in the axial direction. Such design is conducive to control of the transverse structure size.

[0048] In this example, the fixed part 4 is designed in an axial shape, the gear transmission structure is provided with three annular carriers 7 arranged side by side, has three sun gears 5 and three groups of planetary gears, as shown in Figure 7 , the fixed part 4 is connected with the right end sun gear 5 of the gear transmission structure and is output through the left end annular carrier 7 of the gear transmission structure.

[0049] In this case, the left end carrier 7 is connected with an output shaft, the output shaft is connected with a coupling first part 35, the coupling first part 35 is used for being connected with a coupling second part 36 connected with the second driving shaft 12 of the reciprocating structure, the coupling first part 35 and the coupling second part 36 are axially detachably connected and connected to be circumferentially drivingly connected, and the gear transmission structure and the reciprocating structure are axially detachably connected and connected to be circumferentially drivingly connected through the coupling first part 35 and the coupling second part 36. In this way, the structure is simple and reliable, and the connection is convenient.

[0050] In this case, the gear ring 6 is axially detachably sleeved with the rotating cylinder body 2 and circumferentially drivingly connected after being sleeved, the left end cover 31 is fixed to the left end of the gear ring 6, the right end cover 32 is fixed to the right end of the gear ring 6, the left end cover 31, the gear ring 6 and the right end cover 32 surround a cavity, and the planetary gear, the carrier 7 and the sun gear 5 are arranged in the cavity. In this way, the planetary gear, the carrier 7 and the sun gear 5 are protected, the structure is compact, and the modular structure described below is formed.

[0051] In this case, the left end cover 31 and the right end cover 32 are both provided with bearings, the bearing of the right end cover 32 is connected with the fixed part 4, the bearing of the left end cover 31 is connected with the output shaft, and the insertion part of the fixed part 4 is connected with the sun gear 5, so that the rotating cylinder body 2 can rotate relative to the fixed part 4, that is, the other end of the rotating cylinder body 2 can rotate relative to the second side 26, and at the same time, the sun gear 5 is fixed. In this way, the structure is compact, and the size of the control structure is controlled.

[0052] In this case, the structure that one end of the rotating cylinder body 2 rotates relative to the first side 25 includes a first bearing 16 arranged at one end of the rotating cylinder body 2 and a rotating connection shaft 27, the first bearing 16 is fixedly arranged on the handle 39, the rotating connection shaft 27 is connected with the first bearing 16, the first bearing 16 rotatably supports the rotating connection shaft 27, and the rotating connection shaft 27 is fixed with the rotating cylinder body 2. In this way, the structure that one end of the rotating cylinder body 2 rotates relative to the first side 25 is realized through the rotating connection of the rotating connection shaft 27 and the first bearing 16.

[0053] As shown in Figure 7 , 8 , the reciprocating structure includes a rotating body 8, the rotating body 8 is circumferentially provided with a track 9, the track 9 is matched with a driving piece 10, and the driving piece 10 is connected with the blade 1. In this way, the structure is simple, and the reciprocating movement is reliable.

[0054] The track 9 employs a guide groove that is axially spirally arranged on the circumferential surface of the rotating body 8. Both ends of the drive component 10 are equipped with balls 15, and the drive component 10 and the guide groove are engaged by the balls 15 in a rolling fit. This design facilitates control of the lateral dimensions and reduces motion friction, thus improving reciprocating motion. Other friction-reducing structures can also be used, but these will not be elaborated upon here.

[0055] Additionally, the rotating body 8 is connected to a second drive shaft 12. The second drive shaft 12 is axially reciprocatingly sleeved with the rotating body 8 and circumferentially connected for transmission. Elastic elements 13 are provided at both ends of the rotating body 8, which elastically support the rotating body 8. This design is an important anti-jamming design for the blade 1. According to the aforementioned design, when the blade 1 cannot move due to an accident, the rotating body 8 will move axially along the second drive shaft 12, while the rotating cylinder 2 can still rotate. This protects the blade 1, the rotating body 8, the gear transmission structure, the rotating cylinder 2, and other related structures. Furthermore, it allows for adjustment of the cutting force of the blade 1 by selecting different elastic elements 13 or elastic elements 13 with variable elasticity. In other words, it provides a technical means that allows for relatively easy adjustment of the cutting force, which is of great significance.

[0056] In this example, to facilitate production and assembly, an axially reciprocating and circumferentially driven connection structure is used. For example, the rotating body 8 is provided with an axial groove, and the right part is provided with an axial protrusion in the circumferential direction. The axial groove and the axial protrusion are axially sleeved and movably fitted.

[0057] To facilitate the installation of the elastic element 13, a compression spring is used. The right portion has washers 14 at both ends, designated as a left washer 14 and a right washer 14. A compression spring is placed between the left washer 14 and the left side of the rotating body 8, and between the right washer 14 and the right side of the rotating body 8. This design ensures a reliable connection. Furthermore, the compression degree of the spring can be changed by adjusting the position of the washers 14, thereby altering the cutting force of the blade 1. Additionally, it improves the versatility of components, eliminating the need to prepare too many different types of compression springs.

[0058] The output shaft is inserted into the cavity via the left end cover 31 and is connected to the planetary carrier 7.

[0059] Through the above design, a relatively independent module can be obtained, which includes an output shaft, a left end cover 31, a planetary gear transmission mechanism, a right end cover 32, and a fixed part 4. That is, the aforementioned components can be assembled into a module, and then the module can be connected to other structures of the trimming roller brush, which greatly facilitates production assembly, and also results in higher production quality and is conducive to stable production quality.

[0060] In the example, the reciprocating structure is arranged in the independent compartment 20. This design is advantageous for protecting the reciprocating structure, and in addition, the left and right partitions of the compartment 20 can simultaneously serve as the mounting positions of the third bearing 28 and the fourth bearing 29, and the third bearing 28 and the fourth bearing 29 rotate to support the second driving shaft 12. Therefore, the structure is compact, and in addition, the left and right partitions provide certain strength, so that the rotating cylinder body 2 is more stable.

[0061] In order to achieve better hair winding prevention performance, the second side 26 and the rotating cylinder body 2 are provided with a sealing ring 19. In the example, specifically, the second side 26 is provided with a rotating fitting sleeve 18, and the sealing ring 19 is sleeved between the peripheral wall of the other end (i.e. the right end) of the rotating cylinder body 2 and the rotating fitting sleeve 18. The sealing ring 19 rotates together with the rotating cylinder body 2. The sealing ring 19 is, for example, an oil seal.

[0062] In order to more conveniently axially detachably connect the gear transmission structure and the rotating cylinder body 2 and connect them in the circumferential direction after connection, and effectively control the lateral dimension, as shown in Figure 3 , 4 As shown in the figure, the gear transmission structure is provided with an axial connecting piece 33 at the end close to the reciprocating structure, and the gear ring 6 and the rotating cylinder body 2 are axially detachably connected through the axial connecting piece 33. After axial connection, the axial connecting piece 33 simultaneously serves as a circumferential transmission connecting piece for rotating the rotating cylinder body 2 to drive the gear ring 6 to rotate. The axial connecting piece 33 is two, and is uniformly distributed in the circumferential direction at the end of the gear transmission structure close to the reciprocating structure.

[0063] In understanding the present application, if necessary, the above structure can refer to other embodiments / attached Figure 1 It is understood that the above is not repeated here.

[0064] The above description is only an embodiment of the present application for illustration, so equivalent changes or modifications made according to the structure, features and principles described in the patent protection scope of the present application are included in the patent protection scope of the present application.
