Detailed Implementation

[0022] In garment processing equipment (such as washing machines), the inner drum needs to rotate at different speeds during different operating stages. For example, during the washing process, the inner drum typically rotates at a lower speed to ensure that the clothes are in full contact with water and detergent; while during the spin-drying process, the inner drum needs to rotate at a higher speed to remove as much water as possible from the clothes.

[0023] As people's pursuit of quality of life increases, the demand for small / micro washing machines is gradually growing. These machines are convenient, time-saving, and water-saving for washing small items such as underwear and socks. However, small washing machines are smaller in size and have limited manufacturing costs. Compared to large washing machines, which can use inverter motors or add gearboxes to switch drum speeds, using such devices in small washing machines would greatly increase manufacturing costs, and the limited space makes it difficult to accommodate complex gearbox structures.

[0024] Based on the above considerations, this application proposes a garment processing device that can switch the power of the inner drum rotation speed, and has stable operation, simple structure and low cost, making it well applicable to small garment processing equipment.

[0025] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0026] Figure 1 This is a partial structural schematic diagram of a garment processing device 1000 provided in one embodiment of this application. Figure 2This is another partial structural schematic diagram of the clothing processing device 1000 provided in one embodiment of this application.

[0027] Please see Figure 1 and Figure 2 The clothing processing device 1000 provided in this application embodiment includes an inner cylinder 1001, a power assembly 420, and a switching mechanism 430.

[0028] The inner drum 1001 is used to hold the clothes to be processed. The inner drum 1001 can be installed inside the outer drum 1002. The outer drum 1002 serves to support the inner drum 1001, the power assembly 420, and the switching mechanism 430. The inner drum 1001 is connected to an output shaft 410, which is used to transmit power. The output shaft 410 is fixedly connected to the inner drum 1001, and the rotation of the output shaft 410 drives the rotation of the inner drum 1001.

[0029] The power assembly 420 includes a first power wheel 424 and a second power wheel 425, wherein the first power wheel 424 and the second power wheel 425 rotate at different speeds. The first power wheel 424 and the second power wheel 425 can be a gear structure. By setting the first power wheel 424 and the second power wheel 425, power output at different speeds can be achieved. The specific number of power wheels is not limited and is determined according to actual needs. When two or more gear ratios are required, three or more power wheels can be provided.

[0030] The first drive wheel 424 and the second drive wheel 425 can be driven by a motor 421, and a single motor 421 can drive both the first drive wheel 424 and the second drive wheel to rotate. The rotational speeds of the first drive wheel 424 and the second drive wheel 425 can be set according to actual needs. For example, the rotational speed of the first drive wheel 424 can be 500 RPM (revolutions per minute), and the rotational speed of the second drive wheel 425 can be 50 RPM, meaning the first drive wheel 424 is a high-speed wheel and the second drive wheel 425 is a low-speed wheel. This will be used as an example for further explanation later.

[0031] The switching mechanism 430 includes a drive assembly 431 and a driven wheel 432. The driven wheel 432 is coupled to the output shaft 410 and is arranged along the axial direction of the output shaft 410. The drive assembly 431 drives the driven wheel 432 to mesh with the first power wheel 424 or the second power wheel 425 so that the driven wheel 432 drives the output shaft 410 to rotate at different speeds.

[0032] Driven wheel 432 is a gear structure that can mesh with the drive wheel. By coupling driven wheel 432 to output shaft 410, when driven wheel 432 meshes with the first drive wheel 424 or the second drive wheel 425, the torque of the corresponding drive wheel can be transmitted to output shaft 410 through driven wheel 432, thereby driving output shaft 410 to rotate. The position of driven wheel 432 can be changed, allowing it to mesh with different drive wheels. Different drive wheels output different speeds, thus the speed of driven wheel 432 varies, thereby driving output shaft 410 and inner cylinder 1001 to switch between different speeds.

[0033] By setting the drive assembly 431, the driven wheel 432 is driven to move on the output shaft 410, so that it meshes with the first power wheel 424 or the second power wheel 425. The drive assembly 431 can be an electric push rod, a cylinder, a hydraulic cylinder, or other suitable drive device, which is not specifically limited here. The operation of the drive assembly 431 can be controlled by a controller (such as a PLC or microprocessor), which automatically switches the position of the driven wheel 432 according to the operation stage of the washing machine.

[0034] In actual operation, taking the washing and spin-drying stages of the garment processing equipment 1000 as examples, during the washing stage, the controller drives the driven wheel 432 to mesh with the second power wheel 425. At this time, the driven wheel 432 drives the output shaft 410 to rotate at a lower speed via the second power wheel 425, thereby driving the inner drum 1001 to rotate at a lower speed, ensuring that the clothes can fully contact the water and detergent. During the spin-drying stage, the controller drives the driven wheel 432 to mesh with the first power wheel 424. At this time, the driven wheel 432 drives the output shaft 410 to rotate at a higher speed via the first power wheel 424, thereby driving the inner drum 1001 to rotate at a higher speed, removing as much water as possible from the clothes. Compared to using a variable frequency motor 421, this application achieves multi-level speed regulation through a simple mechanical structure, reducing costs. By meshing the driven wheel 432 with different power wheels, the structure of the gearbox is simplified, the complexity of the equipment is reduced, and the reliability of use is improved. It is suitable for small garment processing equipment 1000 and solves the problem of difficulty in achieving multi-level speed regulation due to limited space in the prior art.

[0035] According to the embodiments of this application, the clothing processing device 1000, by setting a driven wheel 432 and a first power wheel 424 and a second power wheel 425, and by driving the driven wheel 432 to mesh with different power wheels through the drive assembly 431, can realize the switching of power output to the output shaft 410, and the operation is stable. It has a simple structure and low cost, and can be well applied to small clothing processing devices 1000.

[0036] Figure 3This is a schematic diagram of the assembly structure of the output shaft 410, the drive wheel, the driven wheel 432 and the drive assembly 431 provided in an embodiment of this application.

[0037] Please see Figure 2 and Figure 3 According to some embodiments of this application, the driven wheel 432 may include a first tooth and a second tooth. The first tooth may engage with the first driving wheel 424, and the second tooth may engage with the second driving wheel 425.

[0038] Understandably, the number of teeth on the driven wheel 432 can be set according to actual needs. When the power assembly 420 includes a first power wheel 424 and a second power wheel 425, the driven wheel 432 can be provided with a first tooth and a second tooth; if there are more power wheels, the number of teeth on the driven wheel 432 can be increased accordingly.

[0039] The first tooth meshes with the first power wheel 424, and the second tooth meshes with the second power wheel 425. When the driven wheel 432 moves to the corresponding position, the corresponding tooth meshes with the corresponding power wheel to realize power transmission. By setting multiple teeth, the overall structure can be flexibly arranged, improving the machining accuracy and meshing stability. Each tooth can be designed for the corresponding power wheel, and the size and shape design of different power wheels are also more flexible. When transmitting at different speeds, corresponding gear ratios and tooth configurations can be designed to improve the overall running stability. When the first power wheel 424 and the second power wheel 425 are different in size, the position setting is also more flexible.

[0040] In actual operation, taking the driven wheel 432 having a first tooth and a second tooth as an example, when the driven wheel 432 is in its initial position, the second tooth can mesh with the second power wheel 425. When it is necessary to switch the speed, the drive assembly 431 pushes the driven wheel 432 to move axially along the output shaft 410, causing the second tooth to disengage from the second power wheel 425. After the driven wheel 432 moves to its final position, the first tooth fully meshes with the first power wheel 424, thereby realizing the switching of speed.

[0041] According to some embodiments of this application, the gear ratio of the first tooth and the first drive wheel 424 is the same as the gear ratio of the second tooth and the second drive wheel 425.

[0042] Gear ratio refers to the ratio of the number of teeth between the teeth of the driven wheel 432 and the corresponding driving wheel. The gear ratio of the first tooth section and the first driving wheel 424 is the same as the gear ratio of the second tooth section and the second driving wheel 425. No matter which driving wheel the driven wheel 432 is switched to, the transmission ratio between the driving wheel and the driven wheel 432 is fixed. Because the driving wheels themselves rotate at different speeds, different speeds can be achieved even with the same transmission ratio.

[0043] Maintaining the same gear ratio ensures the stability and consistency of the transmission system at different speeds, improving the reliability and service life of the equipment. Furthermore, because the gear ratio is the same, the wear of each component is more even, reducing maintenance costs and frequency.

[0044] Please see Figure 3 and Figure 4 According to some embodiments of this application, the first power wheel 424 and the second power wheel 425 are sleeved outside the output shaft 410 and spaced apart along the axial direction of the output shaft 410. The first power wheel 424 and the second power wheel 425 are rotatably disposed relative to the output shaft 410, and the driven wheel 432 is disposed between the first power wheel 424 and the second power wheel 425.

[0045] The first drive wheel 424 and the second drive wheel 425 are sleeved on the output shaft 410 and coaxial with it. The first drive wheel 424 and the second drive wheel 425 are rotatably mounted relative to the output shaft 410; that is, neither the first drive wheel 424 nor the second drive wheel 425 is fixedly connected to the output shaft 410, but is mounted on the output shaft 410 via bearings or other means, allowing them to rotate independently. Thus, the output shaft 410 only provides support for the first drive wheel 424 and the second drive wheel 425. The first drive wheel 424 and the second drive wheel 425 are spaced apart to provide installation and movement space for the driven wheel 432. The driven wheel 432 is located between the first drive wheel 424 and the second drive wheel 425, so that when the driven wheel 432 moves along the axial direction of the output shaft 410, it can move between the first drive wheel 424 and the second drive wheel 425, thereby selectively engaging with either the first drive wheel 424 or the second drive wheel 425.

[0046] Please participate Figure 4 It is understandable that the output shaft 410 may be provided with a mounting part for mounting the power wheel. The mounting part and the adjacent part may be arranged in a stepped manner to limit the position of the power wheel and improve the operational stability of the device.

[0047] By mounting the first drive wheel 424, the second drive wheel 425, and the driven wheel 432 all on the output shaft 410, and placing the driven wheel 432 between the first drive wheel 424 and the second drive wheel 425, the structure of the entire transmission system is more compact, saving installation space. The driven wheel 432 has a shorter movement distance between the first drive wheel 424 and the second drive wheel 425, which improves the efficiency of speed switching.

[0048] Please see Figure 3 and Figure 4According to some embodiments of this application, the driven wheel 432 is provided with a first driven surface tooth portion 4321 and a second driven surface tooth portion 4322 facing away from each other at both ends of the output shaft 410, the first power wheel 424 is provided with a first power surface tooth portion 4241 opposite to the first driven surface tooth portion 4321, and the second power wheel 425 is provided with a second power surface tooth portion 4251 opposite to the second driven surface tooth portion 4322.

[0049] The driven wheel 432 has a first driven surface tooth 4321 and a second driven surface tooth 4322 arranged opposite to each other. That is, the first driven surface tooth 4321 and the second driven surface tooth 4322 face the first driving wheel 424 and the second driving wheel 425, respectively. On the opposite side of the first driving wheel 424 and the second driving wheel 425, there are a first driving surface tooth 4241 and a second driving surface tooth 4251, respectively. Specifically, the first driving wheel 424 has a first driving surface tooth 4241 facing the driven wheel 432, and the first driving surface tooth 4241 can mesh with the first driven surface tooth 4321. The second driving surface tooth 4251 has a second driving surface tooth 4251 facing the driven wheel 432, and the second driving surface tooth 4251 can mesh with the first driven surface tooth 4321. By setting the toothed part, it is convenient for the first driving wheel 424, the second driving wheel 425 and the driven wheel 432 arranged in sequence to mesh, and the meshing is stable and the structure is simple.

[0050] In order to improve the stability of the speed transmission process, the teeth on the first driven surface tooth 4321, the first power surface tooth 4241, the second driven surface tooth 4322, and the second power surface tooth 4251 can all be helical teeth.

[0051] Please see Figure 4 According to some embodiments of this application, the drive assembly 431 may include a connector 4311 that is axially movable along the output shaft 410. The first driven surface tooth portion 4321 and the second driven surface tooth portion 4322 of the driven wheel 432 may be spaced apart along the axial direction of the output shaft 410. The connector 4311 may be rotatably connected to the driven wheel 432 and is located between the first driven surface tooth portion 4321 and the second driven surface tooth portion 4322.

[0052] The first driven surface tooth portion 4321 and the second driven surface tooth portion 4322 are spaced apart from each other, and the opposite side of the first driven surface tooth portion 4321 and the second driven surface tooth portion 4322 can be a plane, so as to form a groove structure between the first driven surface tooth portion 4321 and the second driven surface tooth portion 4322. The connecting member 4311 is partially located in the groove structure between the first driven surface tooth portion 4321 and the second driven surface tooth portion 4322, and the connecting member 4311 and the driven wheel 432 can rotate relative to each other, so that when the connecting member 4311 pushes the driven wheel 432 to move, it does not affect the rotation of the driven wheel 432.

[0053] When the connector 4311 moves circumferentially along the output shaft 410, it abuts against the back of the driven surface tooth on the corresponding side to push the entire driven wheel 432 to move until the driven wheel 432 abuts and engages with the corresponding power wheel.

[0054] In one example, such as Figure 4 As shown, the connector 4311 may include two connecting arms on both sides of the axis of the output shaft 410. By providing two connecting arms, the contact surface between the connector 4311 and the driven wheel 432 is increased. When the connector 4311 pushes the driven wheel 432 to move, the driven wheel 432 is subjected to more uniform force, reducing movement resistance, reducing wear, and improving movement stability.

[0055] Figure 5 This is an assembly diagram of a friction assembly provided in one embodiment of this application. Figure 6 This is a cross-sectional structural schematic diagram of the first friction component 440 provided in an embodiment of this application.

[0056] Please see Figure 5 and Figure 6 According to some embodiments of this application, a friction assembly may be provided between the driven wheel 432 and the first power wheel 424 and the second power wheel 425. The friction assembly may include a driven friction part provided on the driven wheel 432 and a power friction part provided on the first power wheel 424 and the second power wheel 425. When the driven wheel 432 moves closer to the corresponding power wheel, the driven friction part and the power friction part slide in cooperation before the driven wheel 432 engages with the corresponding power wheel.

[0057] The driven friction part is located on the driven wheel 432 and can rotate with the driven wheel 432. The driving friction part is located on the driving wheel and can rotate with the driving wheel. It can be understood that both the driven friction part and the driving friction part are made of wear-resistant materials, and the friction resistance coefficient of the friction surface is relatively large, so that they can play a similar role to a brake or clutch when the driven friction part and the driving friction part come into contact and rub.

[0058] The friction assembly between the driven wheel 432 and the first driving wheel 424 is designated as the first friction assembly 440, and the friction assembly between the driven wheel 432 and the second driving wheel 425 is designated as the second friction assembly 450. The following explanation will focus on the first friction assembly 440; the specific configuration of the second friction assembly 450 can be referenced from the first friction assembly 440.

[0059] When the driven wheel 432 moves towards the first driving wheel 424, the first driven friction part 441 and the first driving friction part 443 contact each other before the driven wheel 432 meshes with the first driving wheel 424, that is, before the first driven surface tooth part 4321 and the first driving surface tooth part 4241 mesh. Thus, under the action of friction, the first driving friction part 443 connected to the first driving wheel 424 can drive the rotational speed of the first driven friction part 441 to gradually approach the rotational speed of the first driving wheel 424, thereby driving the rotational speed of the driven wheel 432 to gradually approach the rotational speed of the first driving wheel 424. Therefore, before the first driven surface tooth part 4321 and the first driving surface tooth part 4241 rigidly mesh, their rotational speeds are brought closer together, reducing wear caused by tooth grinding during meshing and improving service life.

[0060] A friction assembly may be provided between the driven wheel 432 and the first driving wheel 424, or a friction assembly may be provided between the driven wheel 432, the first driving wheel 424, and the second driving wheel 425.

[0061] like Figure 5 and Figure 6 As shown, in one example, a friction assembly is provided between the driven wheel 432 and the first driving wheel 424.

[0062] When starting in the low-speed mode of the inner cylinder 1001, because the second drive wheel 425 has a low speed and high torque, the second driven surface teeth 4322 of the driven wheel 432 and the second drive surface teeth 4251 of the second drive wheel 425 can be directly engaged. Even if the second drive wheel 425 starts first, and then drives the second driven surface teeth 4322 and the second drive surface teeth 4251 of the driven wheel 432 to mesh, the wear is relatively small because the speed is low.

[0063] When switching from low speed mode to high speed mode, or starting directly from high speed mode, the large difference in rotational speed between the second power wheel 425 and the first power wheel 424 will cause significant wear, even if the driven wheel 432 rotates at low speed first under the drive of the second power wheel 425, and then switches to the side of the first power wheel 424. Therefore, by providing a first friction assembly 440 between the driven wheel 432 and the first driving wheel 424, as the driven wheel 432 approaches the first driving wheel 424, the first driven friction part 441 and the first driving friction part 443 first contact and slide together. Under the action of friction, the rotational speed of the first driven friction part 441 gradually increases, which in turn increases the rotational speed of the first driven surface tooth part 4321, i.e., the driven wheel 432. This reduces the speed difference between the first driven surface tooth part 4321 and the first driving surface tooth part 4241 until the first driven surface tooth part 4321 and the first driving surface tooth part 4241 are rigidly meshed. This greatly reduces the wear between the first driven surface tooth part 4321 and the second driven surface tooth part 4322, thereby improving the overall service life, improving the operational stability, and reducing the noise generated during tooth grinding.

[0064] like Figure 7 As shown, in another example, a friction assembly is provided between the driven wheel 432 and the first driving wheel 424 and the second driving wheel 425.

[0065] In actual operation, when starting the inner cylinder 1001 at low speed, the second power wheel 425 can be started first, and then the driven wheel 432 can be driven to move close to the second power wheel 425. Under the action of the second friction component 450 between the driven wheel 432 and the second power wheel 425, on the one hand, the wear of the second driven surface teeth 4322 of the driven wheel 432 and the second power surface teeth 4251 of the second power wheel 425 can be further reduced. On the other hand, the second power wheel 425 starts without load, which greatly reduces the load on the motor 421, improves the service life of the motor 421, and thus improves the service life of the entire device.

[0066] When switching from low-speed mode to high-speed mode, or starting directly from high-speed mode, please refer to the previous examples, which will not be repeated here.

[0067] The friction assembly provided in the embodiments of this application has a simple structure and high stability, reduces wear between the driving wheel and the driven wheel 432, reduces noise, increases the service life of the whole machine, reduces maintenance costs, and improves user satisfaction.

[0068] Figure 8 This is a partial structural schematic diagram of the first friction assembly 440 provided in an embodiment of this application; Figure 9 This is another partial structural schematic diagram of the first friction assembly 440 provided in an embodiment of this application.

[0069] Please see Figure 8 and Figure 9 According to some embodiments of this application, the friction assembly may further include a driven mounting groove surrounding the driven wheel 432 and a power mounting groove surrounding the power wheel. The driven mounting groove may be disposed opposite to the power mounting groove, the driven friction part may be mounted in the driven mounting groove, and the power friction part may be mounted in the power mounting groove.

[0070] Taking the first friction assembly 440 as an example, the first friction assembly 440 includes a first driven mounting groove 442 annularly disposed around the driven wheel 432. Specifically, the first driven mounting groove 442 is annularly disposed around the first driven surface tooth portion 4321. The first friction assembly 440 also includes a first power mounting groove 444 annularly disposed around the power wheel. Specifically, the first power mounting groove 444 is annularly disposed around the first power surface tooth portion 4241. The first driven friction portion 441 is mounted in the first driven mounting groove 442, and the first power friction portion 443 is mounted in the first power mounting groove 444.

[0071] It is understood that the second friction assembly 450 includes a second driven mounting groove and a second power mounting groove. The second driven friction part is mounted in the second driven mounting groove, and the second power friction part is mounted in the second power mounting groove. For details, please refer to the first friction assembly 440, which will not be repeated here.

[0072] Taking the first friction assembly 440 as an example, the first driven mounting groove 442 is arranged around the first driven surface tooth portion 4321, and the first power mounting groove 444 is arranged around the first power surface tooth portion 4241. The openings of the first driven mounting groove 442 and the first power mounting groove 444 are opposite to each other, allowing the first driven friction portion 441 in the first driven mounting groove 442 to slide with the first power friction portion 443 in the first power mounting groove 444. The sidewalls of the first driven mounting groove 442 and the first power mounting groove 444 respectively protect the first driven friction portion 441 and the first power friction portion 443, improving overall safety performance and the installation stability of the first driven friction portion 441 and the first power friction portion 443. Furthermore, the first driven friction part 441 and the first driving friction part 443 are respectively arranged around the first driven surface tooth part 4321 and the first driving surface tooth part 4241, so as not to interfere with the meshing of the first driven surface tooth part 4321 and the first driving surface tooth part 4241, thus ensuring the stability of operation.

[0073] Figure 10 This is an exploded structural diagram of the drive wheel, driven wheel 432 and first friction assembly 440 provided in an embodiment of this application.

[0074] Please see Figure 9 and Figure 10According to some embodiments of this application, the driven friction part can be elastically connected to the driven mounting groove; and the power friction part can be elastically connected to the power mounting groove.

[0075] Taking the first friction assembly 440 as an example, the first driven friction part 441 can be elastically connected to the first driven mounting groove 442; the first power friction part 443 can be elastically connected to the first power mounting groove 444.

[0076] In order for the first driven friction part 441 and the first driving friction part 443 to make contact and engage before the first driven surface tooth part 4321 and the first driving surface tooth part 4241 mesh, when the first driven surface tooth part 4321 and the first driving surface tooth part 4241 are spaced apart, one of the end faces of the first driven friction part 441 and the first driving surface tooth part 443 needs to be between the first driven surface tooth part 4321 and the first driving surface tooth part 4241, so as to engage and rub against each other before the first driven surface tooth part 4321 and the first driving surface tooth part 4241 mesh. It can be understood that the end face of the first friction part near the second friction part is used for sliding engagement with the second friction part, and the end face of the second friction part near the first friction part is used for sliding engagement with the first friction part.

[0077] In one example, the end face of the first driven friction part 441 near the first driving friction part 443 is located on the side of the first driven surface tooth 4321 near the first driving surface tooth 4241, that is, the end face of the first driven friction part 441 protrudes from the first driven surface tooth 4321. Thus, before the first driven surface tooth 4321 meshes with the first driving surface tooth 4241, the first driven friction part 441 contacts and slides with the first driving friction part 443. Furthermore, the first driven friction part 441 is elastically connected to the first driven mounting groove 442. Specifically, the first driven friction part 441 is connected to the bottom of the first driven mounting groove 442 via an elastic member 445, so that as the first driven surface tooth 4321 continues to move closer to the first driving surface tooth 4241, the first driven friction part 441 compresses the elastic member 445 and gradually retracts into the first driven mounting groove 442. As the compressive elastic force of the elastic element 445 increases, the friction between the first driven friction part 441 and the first driving friction part 443 increases, which can improve the gear shifting effect and reduce wear. Furthermore, because the first driven friction part 441 can retract into the first driven mounting groove 442, premature contact between the first driven friction part 441 and the first driving friction part 443 will not affect the contact and meshing of the first driven surface tooth part 4321 and the first driving surface tooth part 4241.

[0078] The first power friction part 443 can be fixedly installed in the first power mounting groove 444.

[0079] In another example, the end face of the first power friction part 443 near the first driven friction part 441 can be located on the side of the first power surface tooth part 4241 near the first driven surface tooth part 4321. That is, the end face of the first power friction part 443 protrudes from the first power surface tooth part 4241 and is elastically connected in the first power mounting groove 444. For specific implementation, please refer to the foregoing example, which will not be repeated here.

[0080] The first driven friction part 441 can be fixedly installed in the first driven mounting groove 442.

[0081] In another example, while the first driven friction part 441 protrudes from the first driven surface tooth part 4321, the first power friction part 443 also protrudes from the first power surface tooth part 4241. The first driven friction part 441 is elastically connected in the first driven mounting groove 442, and the first power friction part 443 is elastically connected in the first power mounting groove 444. For specific implementation, please refer to the foregoing example, which will not be repeated here.

[0082] Please see Figure 10 Taking the first power friction part 443 elastically connected within the first power mounting groove 444 as an example, a guide post 4432 may be provided on the side of the first power friction part 443 away from the first driven friction part 441, and a guide hole 4441 may be provided at the bottom of the first power mounting groove 444. The guide post 4432 is movably disposed within the guide hole 4441. Specifically, the first friction assembly 440 may further include a first mounting base 4431, on which the first power friction part 443 is mounted, and the guide post 4432 is disposed on the side of the first mounting base 4431 away from the first power friction part 443, to improve the installation stability of the first power friction part 443. The guide post 4432 extends along the extension direction of the output shaft 410. By setting the guide post 4432 and the guide hole 4441, the first power friction part 443 is limited, so that while the first power friction part 443 moves along the extension direction of the output shaft 410, it can rotate under the constraint of the guide hole 4441 and the guide post 4432, thus ensuring the stability of the frictional contact.

[0083] Multiple guide posts 4432 and guide holes 4441 can be provided. The multiple guide posts 4432 are distributed circumferentially along the first driven friction part 441. The stability of the first driven friction part 441 is improved by providing multiple guide posts 4432. The number of guide posts 4432 and guide holes 4441 is not limited.

[0084] Figure 11 This is a partial structural schematic diagram of a garment processing device 1000 provided in an embodiment of this application.

[0085] Please see Figure 11According to some embodiments of this application, the drive component 431 may include a guide 4312, a connector 4311, and a drive mechanism 4313.

[0086] The guide member 4312 can be arranged parallel to the output shaft 410; the connecting member 4311 can be slidably connected to the guide member 4312 and rotatably connected to the driven wheel 432, and the connecting member 4311 can move along the axial direction of the output shaft 410 on the guide member 4312. The drive mechanism 4313 can be coupled to the connecting member 4311, and the drive mechanism drives the connecting member 4311 to move along the axial direction of the output shaft 410.

[0087] The guide member 4312 can be disposed on one side of the output shaft 410 and parallel to the output shaft 410. By setting the guide member 4312, a stable moving path is provided for the connecting member 4311, ensuring that the connecting member 4311 will not deviate from the predetermined direction during movement, thus improving stability. The connecting member 4311 can be slidably connected to the guide member 4312, allowing the connecting member 4311 to slide freely on the guide member 4312, thereby achieving axial movement along the output shaft 410. The connecting member 4311 is rotatably connected to the driven wheel 432, so that the driven wheel 432 can still rotate around the output shaft 410 when pushed by the connecting member 4311, without being restricted by the connecting member 4311. The drive mechanism 4313 can drive the connecting member 4311 to move axially along the output shaft 410, thereby driving the driven wheel 432 to switch between different drive wheels. This drive assembly 431 has a simple structure and high stability.

[0088] Please see Figure 11 In one example, the guide member 4312 can be a guide rod, and the connector 4311 is sleeved on the guide rod. There can be multiple guide rods spaced apart and arranged in parallel. The connector 4311 is slidably connected to the multiple guide rods to improve the operational stability of the connector 4311.

[0089] Please see Figure 11 According to some embodiments of this application, the drive mechanism 4313 may include a wire pulling mechanism and a reset member (not shown in the figure). The wire pulling mechanism and the reset member may be connected to the connector 4311. The wire end of the wire pulling mechanism may be connected to the connector 4311 to drive the connector 4311 to move in a first direction. The reset member drives the connector 4311 to reset in the opposite direction of the first direction.

[0090] A cable-pulling mechanism is a device that achieves drive by pulling a cable. It typically consists of a cable puller, a pulley block, and a cable. The cable end of the cable is connected to the connector 4311, meaning one end of the cable is connected to the cable puller and the other end is connected to the connector 4311. The cable puller operates by pulling the cable, which in turn moves the connector 4311.

[0091] It should be noted that the first direction is the direction along the axial direction of the output shaft 410 towards one of the drive wheels. In the initial state, the connector 4311, under the action of the reset member, pushes the driven wheel 432 to maintain engagement with one of the drive wheels. When power needs to be switched, the cable puller pulls the connector 4311 along the first direction toward the other drive wheel, thereby pushing the driven wheel 432 toward the other drive wheel. When switching power again, it is only necessary to contact the pulling force of the cable puller. Under the action of the reset member, the connector 4311 resets in the opposite direction and engages with the previous drive wheel again.

[0092] Figure 12 This is an assembly diagram of the output shaft 410 and the driven wheel 432 provided in one embodiment of this application.

[0093] Please see Figure 12 According to some embodiments of this application, the output shaft 410 and the driven wheel 432 can be coupled by splines.

[0094] The output shaft 410 may be provided with an external spline 411 at the position where the driven wheel 432 is installed, and the driven wheel 432 may be provided with an internal spline. The internal spline and the external spline 411 cooperate, and the spline connection can provide a larger contact area, thereby achieving a higher torque transmission capacity, being able to withstand a larger load, and the power transmission is more uniform and stable, reducing vibration and noise, and improving the overall stability of the system.

[0095] By setting a spline connection, stable power transmission is ensured, while the driven wheel 432 can also slide smoothly along the output shaft 410, facilitating power switching.

[0096] Figure 13 This is an assembly diagram of the power assembly 420 provided in one embodiment of this application.

[0097] Please see Figure 13 According to some embodiments of this application, the power assembly 420 may further include a motor 421 and a transmission wheel 423. The transmission wheel 423 may be coupled to the output end of the motor 421. The transmission wheel 423 includes a first transmission tooth 4231 and a second transmission tooth 4232. The first transmission tooth 4231 meshes with a first power wheel 424, and the second transmission tooth 4232 meshes with a second power wheel 425. The gear ratio of the first transmission tooth 4231 and the first power wheel 424 is different from the gear ratio of the second transmission tooth 4232 and the second power wheel 425.

[0098] Motor 421 is the main power source of the entire system. The output end of motor 421 is coupled to transmission wheel 423 so that the torque output by motor 421 can be transmitted to the power wheel through transmission wheel 423. Transmission wheel 423 has a first transmission tooth 4231 and a second transmission tooth 4232 corresponding to the first power wheel 424 and the second power wheel 425 respectively. By setting the gear ratio of the first transmission tooth 4231 and the first power wheel 424 to be different from the gear ratio of the second transmission tooth 4232 and the second power wheel 425, the output speed of each power wheel is different.

[0099] In one example, the axis of the drive wheel 423 may be arranged parallel to the axis of the output shaft 410, and the drive wheel 423 may be rotatably mounted on one side of the output shaft 410 so that the drive wheel 423 may mesh with the first power wheel 424 and the second power wheel 425 mounted on the output shaft 410.

[0100] In actual operation, the motor 421 starts to output torque, and the output end of the motor 421 drives the transmission wheel 423 to rotate. The transmission wheel 423 can drive the first power wheel 424 and the second power wheel 425 to rotate simultaneously. The first power wheel 424 and the second power wheel 425 have different speeds. Therefore, when the driven wheel 432 meshes with different power wheels, the torque and speed transmitted to the output shaft 410 are also different.

[0101] Please see Figure 13 According to some embodiments of this application, the output end of the motor 421 may be provided with a helical gear 422, and the transmission wheel 423 may include a helical tooth portion 4233 that meshes with the helical gear 422.

[0102] The transmission wheel 423 may include a helical gear portion 4233. Exemplarily, the helical gear portion 4233 may be disposed between the first transmission gear portion 4231 and the second transmission gear portion 4232 to improve the stability of power distribution. The torque output by the motor 421 drives the helical gear 422 to rotate. The helical gear 422 meshes with the helical gear portion 4233 to drive the driven wheel 432 to rotate. By setting the helical gear 422 to mesh, not only can transmission between parallel shafts be achieved, but also transmission between intersecting or overlapping shafts can be achieved by adjusting the helix angle. This allows the output shaft 410 of the motor 421 and the axis of the transmission wheel 423 to be misaligned, resulting in more flexible spatial arrangement and easier assembly in a smaller space.

[0103] Furthermore, the helical gear 422 has a larger tooth surface contact area, so when transmitting the same torque, the pressure per unit area is smaller. This helps to reduce wear and improve transmission efficiency, and can also reduce impact and vibration, making the transmission process smoother.

[0104] By setting helical gear 422 and helical tooth section 4233, it has the advantages of simple structure, flexible arrangement and high stability in use.

[0105] According to some embodiments of this application, motor 421 is a fixed-frequency motor.

[0106] Fixed-frequency motors have a fixed speed. Compared with variable-frequency motors, fixed-frequency motors have a simpler structure, higher reliability, and lower failure rate. They do not require complex variable-frequency control circuits, so fixed-frequency motors are cheaper, easier to maintain, and have lower maintenance costs.
