[0002] The present applicant has made in-depth research into the field of cleaning. Through continuous research, the applicant has invented a hair-cutting roller brush.

When the input side is connected to the gear transmission structure, the input side is for driving the gear transmission structure to rotate, and the gear transmission structure rotates to further drive and rotate the rotating cylinder, and the gear transmission structure rotates to drive the reciprocating structure to reciprocate. When the input side is connected to the gear transmission structure, the input side is for driving the gear transmission structure to rotate, and the gear transmission structure rotates to further drive and rotate the rotating cylinder, and the gear transmission structure rotates to drive the reciprocating structure to reciprocate. Gear transmission structure When both are connected to each other, the input side drives the rotary cylinder and the gear transmission structure to rotate together, and the gear transmission structure rotates to drive the reciprocating structure to reciprocate.

[0008] As an improvement, a first drive shaft is provided on the input side, a fixed part is socket-mounted on the first drive shaft, the first drive shaft is rotatable around the fixed part, and the aforementioned gear transmission structure is attached to the fixed part.

[0009] As an improvement, a rotary coupling portion is provided on the first drive shaft, and the rotary coupling portion is coupled to a gear transmission structure, and the rotary coupling portion drives and rotates the gear transmission structure, and the gear transmission structure further drives and rotates the rotary cylinder.

[0021] The following description is intended to disclose the present invention so that those skilled in the art can practice the invention. The embodiments in the following description are merely examples, and those skilled in the art may envision other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, modified technical solutions, improved technical solutions, equivalent technical solutions, and other technical solutions without departing from the spirit and scope of the present invention.

[0022] The present invention will now be described in further detail. It should be noted that "hair cutting" is an abbreviation, and it does not simply mean cutting hair; although cutting hair is of course the main focus, the subject of "hair cutting" also includes objects that can be cut.

[0023] The present invention provides a cleaning device, which comprises a suction port, and the suction port is provided with the aforementioned hair-cutting roller brush. In this application, the term "cleaning device" generally refers to a household or small-sized cleaning device, such as a vacuum cleaner suction head, a sweeper, a floor scrubber, etc. This is also a feature of the hair-cutting brush of the present invention, that is, the overall structural size is suitable for small-sized cleaning devices.

[0024] For example, the cleaning device shown in Figures 1 and 2 is a suction head of a vacuum cleaner. This suction head includes a roller brush holder. The roller brush holder has two sides, a first side 25 and a second side 26. To operate the hair-cutting roller brush of the present invention, a first drive wheel 22, a drive belt 23, and a second drive wheel 24 are provided on the second side 26. The first drive wheel 22 is driven by an electric motor assembly 40, and the first drive wheel 22 drives and rotates the second drive wheel 24 via the drive belt 23. The second drive wheel 24 is connected to the first drive shaft 11, and a second bearing 17 is disposed between the first drive shaft 11 and the second side 26. The second bearing 17 rotatably supports the first drive shaft 11, and the first drive shaft 11 is socketed in the fixed portion 4. The right end of the fixed part 4 is plugged into and fixed in the plug-in fixing hole 37 in the side cover 34 of the second side surface 26, while the left end of the fixed part 4 extends inward so that a gear transmission structure can be attached.

[0025] When installing the hair-cutting roller brush of the present invention, the rotating cylinder 2 is axially socket-mounted toward the gear transmission structure, and the other end of the rotating cylinder 2 is mounted to the second side surface 26 through this axial socket mounting, while one end of the rotating cylinder 2 is axially mounted to the first side surface 25 through an axial socketing motion. When removing the rotating cylinder 2, the gear transmission structure is held on the second side surface 26, and the rotating cylinder 2 is removed in the opposite direction of the axial socketing motion. After removal, the state will be as shown in Figure 3. A removal handle 39 is provided on one end of the rotating cylinder 2 for secure connection and convenient removal. A locking mechanism is provided between the removal handle 39 and the roller brush holder, which can take various forms, and in this example, a snap lock 21 is adopted, as shown in Figure 2. To remove the lock, the snap lock 21 is first released and separated from the insertion hole 38 located on the removal handle 39, after which the rotary cylinder 2 can be removed axially while part of the drive structure, i.e., the gear transmission structure in this example, remains held on the second side. Alternatively, the rotary cylinder 2 can be axially socket-mounted to the gear transmission structure, and at the same time, the rotary cylinder 2 is mounted between the first side 25 and the second side 26, after which the snap lock 21 is engaged and the deadbolt of the snap lock 21 is inserted into the insertion hole 38 to complete the locking.

[0026] The above-mentioned attachment / detachment structure is simple and reliable, and the attachment / detachment operation is convenient without the aid of tools.

[0027] As shown in Figures 2, 3, 6, and 7, the hair-cutting roller brush comprises a blade 1 and a rotating cylinder 2. The blade 1 is provided with a blade head 3. The blade 1 is disposed within the rotating cylinder 2 of the roller brush, and is synchronously driven by a drive mechanism so that as the rotating cylinder 2 rotates, the blade 1 reciprocates and cuts hair. Part or all of the drive mechanism is provided on the second side 26, and the other end of the rotating cylinder 2 is provided with a socket hole that is axially socket-mounted to the portion of the drive mechanism 26 held on the second side 26. The axial socket mounting is for axially mounting the other end of the rotating cylinder 2 to the second side 26 through the axial socket mounting, while at the same time, one end of the rotating cylinder 2 is axially mounted to the first side 25 in accordance with the axial socketing motion. When the rotating cylinder 2 is to be removed, the portion of the drive mechanism held on the second side 26 remains held on the second side 26, and the rotating cylinder 2 is removed in the opposite direction of the axial socketing motion.

[0028] The main function of the drive structure is that it converts the rotational motion of the input side into a reciprocating movement of the blade 1. Any suitable moving part may be applied to the present invention.

[0029] The drive structure includes a gear transmission structure and a reciprocating structure. In this example, the portion of the drive structure held on the second side 26 is referred to as the gear transmission structure. The reciprocating structure is located within the rotary cylinder 2 and can be detached together with the rotary cylinder 2, with the planetary gear transmission mechanism and the reciprocating structure detachably connected. The gear transmission structure is used to drive the reciprocating movement of the reciprocating structure. This promotes structural simplification, achieves the objectives of the present invention, and reduces the complexity and difficulty of setting up the drive structure. Furthermore, the above design primarily relies on the gear transmission structure to handle changes in reciprocating speed, promoting structural simplification. Furthermore, the reciprocating speed can be more accurately controlled, resulting in better hair-cutting results.

[0030] An input side is provided on the second side 26, and the input side is connected to the rotary cylinder 2 and / or the gear transmission structure. When the input side is connected to the rotary cylinder 2, the input side drives the rotary cylinder 2 to rotate, and the rotary cylinder 2 rotates to further drive and rotate the gear transmission structure, and the gear transmission structure rotates to drive the reciprocating structure to move back and forth. When the input side is connected to the gear transmission structure, the input side drives the gear transmission structure to rotate, and the gear transmission structure rotates to further drive and rotate the rotary cylinder 2, and the gear transmission structure rotates to drive the reciprocating structure to move back and forth. When the input side is connected to the gear transmission structure, the input side drives the gear transmission structure to rotate, and the gear transmission structure rotates to further drive and rotate the rotary cylinder 2, and the gear transmission structure rotates to drive the reciprocating structure to move back and forth. Gear transmission structure When both are connected to each other, the input side drives the rotary cylinder 2 and the gear transmission structure to rotate together, and the gear transmission structure rotates to drive the reciprocating structure to reciprocate. This design promotes a compact structure.

[0031] In this example, the input side is connected to the gear transmission structure, and the input side drives the gear transmission structure to rotate, the gear transmission structure further drives the rotating cylinder 2 to rotate, and the gear transmission structure drives the reciprocating structure to reciprocate. This design promotes a compact structure and reduces the size of the structure.

[0032] A first drive shaft 11 is provided on the input side, and a fixed part 4 is socket-mounted on the first drive shaft 11. The first drive shaft 11 is rotatable around the fixed part 4, and the aforementioned gear transmission structure is attached to the fixed part. This design promotes a compact structure and effectively reduces the volume of the entire structure.

[0033] The first drive shaft 11 is provided with a rotary coupling 30, which is coupled to the gear transmission structure, and the gear transmission structure drives and rotates the rotary cylinder 2. This design contributes to a compact structure and effectively reduces the overall volume of the structure.

[0034] The gear transmission structure employs a planetary gear transmission mechanism, with a fixed part 4 provided on the second side 26, a sun gear 5 of the planetary gear transmission mechanism fixedly connected to the fixed part 4, a gear ring 6 of the planetary gear transmission mechanism connected to the rotating cylinder 2, and a planet carrier 7 of the planetary gear transmission mechanism as a transmission output to drive and move the reciprocating structure. This design promotes a compact structure and effectively reduces the overall volume of the structure.

[0035] In addition, the gear ring 6 is provided with a right end cover, which is connected to the rotary connector 30, which drives and rotates the gear ring 6 via the right end cover, and the gear ring 6 further drives and rotates the rotary cylinder. This design promotes a compact structure and effectively reduces the overall volume of the structure.

[0036] As shown in Figure 7, after the hair-cutting roller brush is disposed between the first side surface 25 and the second side surface 26, the fixed part 4, the gear transmission structure, and the reciprocating structure are sequentially disposed axially from right to left along the rotating cylinder 2. In this way, it is easy to reduce the structural size in the lateral direction.

[0037] In this example, the fixed part 4 is designed as an axis, and the gear transmission structure has three planetary carriers 7 arranged in parallel, three sun gears 5, and three sets of planetary gears. As shown in Figure 7, the fixed part 4 is connected to the sun gear 5 at the right end of the gear transmission structure and outputs through the planetary carrier 7 at the left end of the gear transmission structure.

[0038] In this example, the leftmost planetary carrier 7 is connected to the output shaft, which is connected to the first coupling part 35. The first coupling part 35 is connected to the second coupling part 36, which is connected to the second drive shaft 12 of the reciprocating structure. The first coupling part 35 is axially detachably connected to the second coupling part 36, and then circumferentially operably connected. The gear transmission structure and the reciprocating structure realize the axially detachable connection via the first coupling part 35 and the second coupling part 36, and then circumferentially operably connected. This design has a simple structure, high reliability, and convenient connection.

[0039] In this example, the gear ring 6 is axially and detachably mounted in a socket on the rotary cylinder 2, and after being socket mounted, is circumferentially transmission-coupled. A left end cover 31 is fixed to the left end of the gear ring 6, and a right end cover 32 is fixed to the right end of the gear ring 6. The left end cover 31, gear ring 6, and right end cover 32 form a cavity, in which the planet gears, planet carrier 7, and sun gear 5 are disposed. This is advantageous for protecting the planet gears, planet carrier 7, and sun gear 5, and also promotes a compact structure and the formation of a modular structure, which will be described later.

[0040] In this example, both the left end cover 31 and the right end cover 32 are provided with bearings, the bearing of the right end cover 32 is connected to the fixed part 4, the bearing of the left end cover 31 is connected to the output shaft, and the insertion part of the fixed part 4 is connected to the sun gear 5, so that the rotating cylinder 2 can rotate relative to the fixed part 4, i.e., the other end of the rotating cylinder 2 can rotate relative to the second side surface 26, while at the same time the sun gear 5 is fixed and does not move. This type of design helps to make the structure more compact.

[0041] In this example, the structure in which one end of the rotating cylinder 2 rotates relative to the first side surface 25 includes a first bearing 16 arranged at one end of the rotating cylinder 2 and a rotary connecting shaft 27, the first bearing 16 is fixed to the handle 39, the rotary connecting shaft 27 is connected to the first bearing 16, the first bearing 16 rotatably supports the rotary connecting shaft 27, and the rotary connecting shaft 27 is also fixed to the rotating cylinder 2, so that the rotatable connection of one end of the rotating cylinder 2 to the first bearing 16 via the rotary connecting shaft 27 can realize a structure in which one end of the rotating cylinder 2 rotates relative to the first side surface 25.

[0042] As shown in Figures 7 and 8, the reciprocating structure includes a rotor 8 with a circumferential track 9, and a driving member 10 is coupled to the track 9, which is connected to the blade 1. This design has a simple structure and high reciprocating reliability.

[0043] The raceway 9 employs a guide groove disposed around the periphery of the rotor 8 and rotating in the axial direction, and balls 15 are provided on both ends of the driving member 10, and the driving member 10 and the guide groove are fitted with the balls 15 in a rolling manner. This design helps to restrict the lateral size and also reduces friction during movement, making reciprocating movement more convenient. Other anti-friction structures can also be used, but will not be repeated here.

[0044] In addition, a second drive shaft 12 is connected to the rotor 8. The second drive shaft 12 is socket-mounted to the rotor 8 so as to be axially reciprocating and circumferentially transmissively connected thereto. Elastic members 13 are provided at both ends of the rotor 8, respectively, to elastically support the rotor 8. This design is an important anti-jam design for the blade 1. According to the design, if the blade 1 is stuck due to an unexpected event, the rotor 8 moves along the axial direction of the second drive shaft 12, while the rotary cylinder 2 can still rotate. This protects the blade 1, the rotor 8, the gear transmission structure, and other related structures. Furthermore, the rotary cylinder 2 and other related structures can be equipped with different elastic members 13 or elastic members 13 with variable elasticity, facilitating adjustment of the cutting force of the blade 1. Furthermore, this design provides a technical means for relatively easy adjustment of the cutting force, and this simple adjustment of cutting force is of great significance.

[0045] In this example, for the sake of convenience in manufacturing and assembly, the structure of the axially reciprocating socket mounting and circumferentially transmission connection is, for example, such that an axial groove is provided in the rotor 8, and an axial protrusion is provided in the circumferential direction on the right part thereof, and the axial groove and the axial protrusion are axially socket mounted and movably fitted.

[0046] To facilitate the installation of the elastic member 13, the elastic member 13 is a compression spring, and gaskets 14 are provided on both ends of the right section, namely the left gasket 14 and the right gasket 14. Compression springs are disposed between the left gasket 14 and the left side of the rotor 8, and between the right gasket 14 and the right side of the rotor 8, respectively. This design ensures a secure connection. Furthermore, there is another use: by adjusting the position of the gasket 14, the compression degree of the compression spring can be changed, thereby changing the hair-cutting force of the blade 1. This also improves the versatility of the part, eliminating the need to prepare too many different types of compression springs.

[0047] The output shaft is inserted into the cavity via the left end cover 31, and the output shaft is connected to the planetary carrier 7.

[0048] After the above design, a relatively independent module can be obtained, which includes the output shaft, the left end cover 31, the planetary gear transmission mechanism, the right end cover 32, and the fixing part 4, that is, the above-mentioned assembly can be assembled into one module, and then the module can be connected with other structures of the hair-cutting brush, which greatly facilitates production assembly, further improves production quality, and promotes stable production quality.

[0049] In this example, the reciprocating structure is arranged in an independent compartment 20. This design contributes to protecting the reciprocating structure, and in addition, the left and right partitions of the compartment 20 can also be used as mounting positions for the third bearing 28 and the fourth bearing 29, which rotationally support the second drive shaft 12, making the structure compact and the left and right partitions also providing a certain amount of strength, making the structure of the rotary cylinder 2 more stable.

[0050] To achieve better hair curl prevention performance, a seal ring 19 is disposed between the second side surface 26 and the rotary cylinder 2. Specifically, in this example, a rotary matching sleeve 18 is provided on the second side surface 26, and the seal ring 19 is sleeved between the peripheral wall of the other end (i.e., the right end) of the rotary cylinder 2 and the rotary matching sleeve 18, and the seal ring 19 rotates together with the rotary cylinder 2. The seal ring 19 is, for example, an oil seal.

[0051] To facilitate the axially detachable connection between the gear transmission structure and the rotating cylinder 2 and the subsequent circumferentially transmission connection therebetween while effectively reducing the lateral size, an axial connector 33 is provided at one end of the gear transmission structure near the reciprocating structure, as shown in Figures 3 and 4. The gear ring 6 and the rotating cylinder 2 are axially detachably connected by the axial connector 33. After the axial connection, the axial connector 33 also serves as a circumferential transmission connector, allowing the rotating cylinder 2 to drive the gear ring 6 to rotate together. There are two axial connectors 33, which are evenly distributed circumferentially along the end of the gear transmission structure near the reciprocating structure.

[0052] In understanding the present invention, the above structure can be understood by referring to other embodiments and drawings as necessary, and will not be repeated here. It should be noted that the above is only an illustrative embodiment of the present invention, and all equivalent changes or modifications made according to the structures, features and principles described in the protection scope of the present invention patent are included in the protection scope of the present invention patent.
