Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a cleaning device and a battery production system. Background Art

[0002] Energy conservation and emission reduction are key to sustainable development, which in turn promotes the adjustment of energy structure and drives the development and application of battery technology. The key to the development of battery technology lies in electrochemical energy storage technology. Due to its advantages such as high energy density, good cycle life, high operating voltage, environmental friendliness, and low self-discharge, it has been widely used in portable electronics, electric vehicles, and energy storage systems.

[0003] During battery production, cleaning equipment is required to remove impurities from the production environment to reduce the risk of negative impacts. For example, after welding, welding slag particles need to be removed using a cleaning device. However, improving the cleaning efficiency of cleaning equipment has become a pressing technical challenge. Utility Model Content

[0004] The main purpose of this application is to provide a cleaning device and a battery production system, aiming to solve the technical problem of poor cleaning effect of the cleaning device in the prior art.

[0005] To solve the above problems, the present application provides a cleaning device, the cleaning device comprising a drive assembly, a first transmission wheel, a second transmission wheel and a cleaning member, the first transmission wheel being connected to the drive assembly, the drive assembly being used to drive the first transmission wheel to rotate about a first axis; the second transmission wheel being connected to the drive assembly, the second transmission wheel and the first transmission wheel being spaced apart along the first axis, the drive assembly being used to drive the second transmission wheel to rotate about the first axis; the cleaning member comprising a transmission rod and a cleaning portion connected to each other, the transmission rod extending along the second axis, the first axis and the second axis being parallel but not overlapping, the transmission rod being connected to the first transmission wheel and the second transmission wheel respectively, the first transmission wheel being used to drive the transmission rod to revolve around the first axis, and the second transmission wheel being used to drive the transmission rod to rotate about the second axis. Thus, the first transmission wheel and the second transmission wheel can be driven to rotate about the first axis by the drive assembly, the transmission rod of the cleaning member extending along the second axis and being connected to the first transmission wheel and the second transmission wheel respectively, so that the first transmission wheel drives the transmission rod to revolve around the first axis, and the second transmission wheel drives the transmission rod to rotate about the second axis, so that the cleaning member can simultaneously revolve and rotate, thereby increasing the cleaning range of the cleaning member, reducing the cleaning blind spot, and improving the cleaning effect.

[0006] In some embodiments, the first transmission wheel includes a first gear and a rotating bearing. The first gear is connected to a drive assembly, the drive assembly is configured to drive the first gear to rotate about a first axis, the rotating bearing is connected to the first gear, and the transmission rod is inserted into the rotating bearing. Thus, the transmission rod is inserted into the rotating bearing, and the rotating bearing is connected to the first gear. The rotating bearing provides support for the transmission rod and reduces rotational friction between the transmission rod and the first gear, facilitating rotation of the transmission rod about a second axis while in orbit about the first axis, thereby improving the rotational stability of the transmission rod.

[0007] In some embodiments, the first transmission wheel includes a bearing mount that is sleeved around the outer side of the rotating bearing, and the rotating bearing is connected to the first gear via the bearing mount. Thus, the bearing mount provides support and fixation for the rotating bearing, improving the stability of the connection between the rotating bearing and the first gear.

[0008] In some embodiments, the rotary bearing is located on a side of the first gear facing away from the second transmission wheel. The first gear is provided with a first through-hole, and the transmission rod is passed through the first through-hole and inserted into the rotary bearing. Thus, by passing the transmission rod through the first through-hole and inserted into the rotary bearing, the transmission rod is easily connected to the first gear, thereby improving the stability of the transmission rod driven by the first gear to rotate about the first axis, and at the same time facilitating the rotary bearing to provide support for the transmission rod.

[0009] In some embodiments, the second transmission wheel includes a second gear having a second through-hole, an inner wall of the second through-hole having internal teeth, a transmission rod extending through the second through-hole, and external teeth being provided on the transmission rod at positions corresponding to the internal teeth, the internal teeth meshing with the external teeth. Thus, the meshing of the external teeth on the transmission rod with the internal teeth on the inner wall of the second through-hole facilitates the second gear's rotation around the first axis, thereby driving the transmission rod to rotate around its own second axis, thereby improving the stability of the transmission rod's rotation around the second axis.

[0010] In some embodiments, the ratio of the self-rotational speed to the orbital speed of the transmission rod is proportional to the ratio of the number of teeth of the inner and outer teeth. Thus, the ratio of the self-rotational speed to the orbital speed of the transmission rod can be adjusted by adjusting the ratio of the number of teeth of the inner and outer teeth, facilitating flexible adjustment of the transmission rod's speed, thereby improving cleaning performance.

[0011] In some embodiments, the drive assembly includes a drive motor and a power dispersion wheel, the power dispersion wheel being connected to the output terminal of the drive motor, and the first transmission wheel and the second transmission wheel being respectively connected to the power dispersion wheel. Thus, the power output from the drive motor can be transmitted to the first transmission wheel and the second transmission wheel respectively via the power dispersion wheel, thereby facilitating the drive motor to simultaneously drive the first transmission wheel and the second transmission wheel to rotate independently about the first axis. This eliminates the need for multiple power sources to separately drive the first transmission wheel and the second transmission wheel, thereby reducing the size of the cleaning device and saving production costs.

[0012] In some embodiments, the first transmission wheel includes a first gear, the second transmission wheel includes a second gear, and the power dispersion wheel includes a third gear and a fourth gear. The third gear and the fourth gear are spaced apart, the first gear and the third gear are meshed, and the second gear and the fourth gear are meshed. Thus, the third gear can drive the first gear to rotate about the first axis, while the fourth gear can drive the second gear to rotate about the first axis. This facilitates the drive motor to simultaneously drive the first gear and the second gear to rotate independently about the first axis, eliminating the need for multiple power sources to separately drive the first gear and the second gear, thereby reducing the size of the cleaning device and saving production costs.

[0013] In some embodiments, the ratio of the transmission rod's rotational speed to its orbital speed is inversely proportional to the gear ratio of the first gear to the third gear; and / or, the ratio of the transmission rod's rotational speed to its orbital speed is directly proportional to the gear ratio of the second gear to the fourth gear. Thus, the ratio of the transmission rod's rotational speed to its orbital speed can be adjusted by adjusting the gear ratio of the first gear to the third gear or the gear ratio of the second gear to the fourth gear, thereby facilitating flexible adjustment of the transmission rod's rotational speed, thereby improving cleaning performance.

[0014] In some embodiments, the ratio of the self-rotation speed to the orbital speed of the transmission rod is between 1 and 30. Thus, by setting the ratio of the self-rotation speed to the orbital speed of the transmission rod between 1 and 30, the self-rotation speed and the orbital speed of the transmission rod can be more flexibly matched with actual cleaning requirements, thereby improving the cleaning effect.

[0015] In some embodiments, the cleaning device further includes a reversing wheel, wherein the second transmission wheel is connected to the drive assembly via the reversing wheel, and the reversing wheel is configured to drive the second transmission wheel to rotate in a direction opposite to the first transmission wheel. Thus, by causing the second transmission wheel to rotate in a direction opposite to the first transmission wheel via the reversing wheel, the ratio of the rotational speed to the orbital speed of the transmission rod can be increased, thereby improving the cleaning effect.

[0016] In some embodiments, the cleaning portion is extended along the second axis. Thus, by extending the cleaning portion along the second axis, the cleaning portion can simultaneously rotate and revolve under the drive of the transmission rod, thereby increasing the cleaning range of the cleaning portion and improving the cleaning effect.

[0017] In some embodiments, the cleaning device includes a hollow tube having a receiving cavity extending along a first axis, wherein the transmission rod is at least partially located within the receiving cavity, and the cleaning unit is at least partially located outside the receiving cavity. Thus, the receiving cavity can accommodate at least a portion of the transmission rod, so that the hollow tube provides protection for the transmission rod and reduces the risk of damage to the transmission rod. Meanwhile, the cleaning unit is at least partially located outside the receiving cavity, facilitating cleaning of the area to be cleaned outside the hollow tube.

[0018] In some embodiments, the hollow tube is provided with at least one suction port connected to the receiving chamber. Thus, the suction port can create a negative pressure region within the receiving chamber to absorb impurity particles removed by the cleaning portion, thereby effectively collecting the impurity particles and mitigating the risk of impurity particles being scattered to other areas due to untimely collection.

[0019] In order to solve the above problems, the present application also provides a battery production system, which includes the above cleaning device. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Currently, market developments indicate that batteries are increasingly being used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. As battery applications continue to expand, market demand is also growing.

[0038] During the battery production process, cleaning devices are required to clean foreign particles in the production environment to reduce the risk of negative impacts on battery production. However, current cleaning devices have poor cleaning effects.

[0039] To solve the technical problems existing in the related art, a cleaning device is provided. A driving assembly can drive a first transmission wheel and a second transmission wheel to rotate about a first axis. A transmission rod of a cleaning member is connected to the first transmission wheel and the second transmission wheel, respectively. The first transmission wheel can drive the transmission rod to orbit around the first axis, and the second transmission wheel can drive the transmission rod to rotate about the second axis. This allows the cleaning member to simultaneously orbit and rotate during the cleaning process, reducing blind spots and improving the cleaning effect of the cleaning device.

[0040] Please refer to Figure 1 , Figure 1 Schematic diagram of the structure of a battery production system according to one or more embodiments of the present application.

[0041] The present application also provides a battery production system 2, comprising a cleaning device 1. Battery production system 2 can be used to produce battery cells 3, etc. Cleaning device 1 can clean an area to be cleaned within battery production system 2. For example, cleaning device 1 can remove foreign particles from the area to be cleaned, thereby mitigating the risk of foreign particles invading the structure of battery cells 3 and causing damage to the battery cells 3.

[0042] A battery device generally includes a housing and battery cells 3, with the battery cells 3 being housed within the housing. In a battery, there may be multiple battery cells 3, which may be connected in series, in parallel, or in a hybrid configuration. A hybrid configuration refers to multiple battery cells 3 being connected in both series and parallel. Multiple battery cells 3 may be directly connected in series, in parallel, or in a hybrid configuration, and then the entirety formed by the multiple battery cells 3 may be housed within the housing. Of course, the battery device may also include multiple battery cells 3 first connected in series, in parallel, or in a hybrid configuration to form a battery module, which may then be connected in series, in parallel, or in a hybrid configuration to form a whole, and housed within the housing. The battery device may also include other structures. For example, the battery may also include a busbar component for achieving electrical connection between the multiple battery cells 3.

[0043] Battery cells 3 can be manufactured in two ways: laminated and wound. Laminated batteries offer uniform current collection, low internal resistance, and high specific power. However, to improve precision, they require extremely high mold accuracy, high equipment investment, and a relatively complex process, resulting in low production efficiency. Wound batteries are simple to manufacture, with moderate equipment precision requirements during the production and assembly processes. They offer high production efficiency and low cost. In terms of performance, wound batteries offer excellent high and low temperature performance, rapid charging, an extremely long lifespan, stable high output voltage, a sturdy structure, and strong shock resistance.

[0044] A battery cell 3 is the smallest unit that makes up a battery device. A battery cell 3 may include a housing, an electrode assembly, and other functional components. The electrode assembly is the part of the battery cell 3 where the electrochemical reaction occurs. The housing may contain one or more electrode assemblies. The electrode assembly is primarily composed of a positive electrode sheet and a negative electrode sheet wound or stacked, typically with a separator between the positive and negative electrode sheets.

[0045] The electrode sheet can be a positive electrode sheet or a negative electrode sheet. The portion of the electrode sheet with active material constitutes the main body of the electrode assembly, and the portion of the electrode sheet without active material each constitutes a tab. During the charge and discharge process of the battery, the active material reacts with the electrolyte, and the tabs connect the electrode terminals to form a current loop. The active material can be coated on the electrode sheet in the form of a slurry to form a film layer on the electrode sheet, and the film layer can be fixed to the electrode sheet by baking and rolling. The material of the slurry can include but is not limited to lithium-containing phosphates, lithium transition metal oxides and their respective modified compounds, artificial graphite, natural graphite, soft carbon, hard carbon, silicon-based materials, tin-based materials and lithium titanate, etc.

[0046] During the battery production process, there may be various impurity particles in the production environment. If the impurity particles are not cleaned promptly and effectively, they may invade the battery structure, leading to risks such as battery damage. For example, in the welding process of the battery cell adapter, welding will produce welding slag particles. If the cleaning effect is not good, the welding slag particles can easily invade the battery structure such as the adapter, causing problems such as abnormal self-discharge of the battery.

[0047] This application provides a cleaning device, please refer to Figure 2 , Figure 2 This is a first structural schematic diagram of a cleaning device according to one or more embodiments of the present application.

[0048] The cleaning device 1 includes a drive assembly 10, a first transmission wheel 20, a second transmission wheel 30 and a cleaning member 40. The first transmission wheel 20 is connected to the drive assembly 10, and the drive assembly 10 is used to drive the first transmission wheel 20 to rotate around the first axis x1; the second transmission wheel 30 is connected to the drive assembly 10, and the second transmission wheel 30 and the first transmission wheel 20 are spaced apart along the first axis x1. The drive assembly 10 is used to drive the second transmission wheel 30 to rotate around the first axis x1; the cleaning member 40 includes a transmission rod 41 and a cleaning portion 42 connected to each other. The transmission rod 41 extends along the second axis x2. The first axis x1 and the second axis x2 are parallel but not coincident. The transmission rod 41 is respectively connected to the first transmission wheel 20 and the second transmission wheel 30. The first transmission wheel 20 is used to drive the transmission rod 41 to revolve around the first axis x1, and the second transmission wheel 30 is used to drive the transmission rod 41 to rotate around the second axis x2.

[0049] The drive assembly 10 can output power, thereby driving the first transmission wheel 20 and the second transmission wheel 30 to rotate about the first axis x1. It should be noted that the drive assembly 10 can drive the first transmission wheel 20 and the second transmission wheel 30 separately. The rotation speeds of the first transmission wheel 20 and the second transmission wheel 30 can be the same or different, and the rotation directions of the first transmission wheel 20 and the second transmission wheel 30 can be the same or different. For example, when viewed from the side of the first transmission wheel 20 away from the second transmission wheel 30 and along the first axis x1, the first transmission wheel 20 can rotate clockwise and the second transmission wheel 30 can also rotate clockwise, or the first transmission wheel 20 can rotate clockwise and the second transmission wheel 30 can rotate counterclockwise, or the first transmission wheel 20 can rotate counterclockwise and the second transmission wheel 30 can rotate clockwise, and so on. The first transmission wheel 20 and the second transmission wheel 30 are spaced apart along the first axis x1, so that the first transmission wheel 20 and the second transmission wheel 30 can rotate independently about the first axis x1. The transmission rod 41 connects the first transmission wheel 20 and the second transmission wheel 30, respectively. For example, the first transmission wheel 20 may include an eccentric cam, with a first axis x1 passing through the eccentric cam's rotation center, allowing the eccentric cam to rotate about the first axis x1. The transmission rod 41 is connected to the eccentric cam, and the intersection of the second axis x2 and the eccentric cam and the eccentric cam's rotation center are offset, thereby enabling the first transmission wheel 20 to drive the transmission rod 41 to revolve about the first axis x1. The second transmission wheel 30 can drive the transmission rod 41 to rotate about the second axis x2, on which the transmission rod 41 itself lies, causing the transmission rod 41 to rotate. It is understood that, as the transmission rod 41 rotates about the first axis x1, the second axis x2 also rotates about the first axis x1. It should be noted that the direction in which the transmission rod 41 revolves about the first axis x1 and the direction in which the transmission rod 41 rotates about the second axis x2 can be the same as or different from the direction in which the transmission rod 41 rotates about the second axis x2. The cleaning section 42 can be used to clean foreign particles. The cleaning section 42 can include, but is not limited to, a brush member, etc. The transmission rod 41 is interconnected with the cleaning section 42 so that the transmission rod 41 can drive the cleaning section 42 to rotate simultaneously about the first axis x1 and about the second axis x2. Compared to the cleaning section 42 rotating only about the second axis x2, the cleaning section 42 can perform rotational cleaning over a wider range, reducing blind spots in cleaning. It is understandable that when the cleaning section 42 rotates only about the second axis x2, the linear velocity of the cleaning section 42 closer to the second axis x2 in the radial direction perpendicular to the second axis x2 is smaller, resulting in poor cleaning effect at locations with lower linear velocity. However, the cleaning section 42 rotates simultaneously about the first axis x1 and about the second axis x2, so that the cleaning section 42 near the second axis x2 can also have a higher linear velocity, thereby effectively improving the cleaning effect. It should be noted that compared to the cleaning section 42 simply performing reciprocating motion along a straight line to clean, rotational cleaning can more effectively reduce the risk of foreign particles being thrown out of the cleaning area and causing the particles to be scattered.

[0050] Through the above embodiment, the first transmission wheel 20 and the second transmission wheel 30 can be driven by the driving component 10 to rotate around the first axis x1, and the transmission rod 41 of the cleaning member 40 is extended along the second axis x2 and is connected to the first transmission wheel 20 and the second transmission wheel 30 respectively, so that the first transmission wheel 20 drives the transmission rod 41 to revolve around the first axis x1, and the second transmission wheel 30 drives the transmission rod 41 to rotate around the second axis x2, so that the cleaning member 40 can revolve and rotate at the same time, thereby increasing the cleaning range of the cleaning member 40, reducing the cleaning blind area, and improving the cleaning effect.

[0051] Please refer to Figure 3-Figure 4 , Figure 3 is a second structural schematic diagram of a cleaning device according to one or more embodiments of the present application, Figure 4 3 is a schematic diagram of the third structure of a cleaning device according to one or more embodiments of the present application.

[0052] The first transmission wheel 20 includes a first gear 21 and a rotating bearing 22. The first gear 21 is connected to the drive assembly 10, which is configured to drive the first gear 21 to rotate about the first axis x1. The rotating bearing 22 is connected to the first gear 21, and the transmission rod 41 is inserted into the rotating bearing 22. The first gear 21 can be meshed with the drive assembly 10. The rotating bearing 22 can be, for example, a ball bearing, a cylindrical roller bearing, a tapered roller bearing, or a needle bearing. The bearing can reduce friction during the rotation of the transmission rod 41, support the transmission rod 41, and withstand radial loads on the transmission rod 41. This application does not limit the number or type of rotating bearings 22. For example, if there is one rotating bearing 22, one rotating bearing 22 can be located on the side of the first gear 21 facing away from the second transmission wheel 30, or on the side of the first gear 21 facing the second transmission wheel 30. If there are two rotating bearings 22, the two rotating bearings 22 can be located on the side of the first gear 21 facing away from the second transmission wheel 30 and on the side of the first gear 21 facing the second transmission wheel 30, respectively. Specifically, the first gear 21 can be an eccentric cam, etc. Thus, the transmission rod 41 is inserted into the rotating bearing 22, and the rotating bearing 22 is connected to the first gear 21. The rotating bearing 22 provides support for the transmission rod 41 and reduces the rotational friction between the transmission rod 41 and the first gear 21, thereby facilitating the transmission rod 41 to rotate about the second axis x2 while in orbit around the first axis x1, thereby improving the rotational stability of the transmission rod 41.

[0053] In some embodiments, the first transmission wheel 20 includes a bearing retainer 23, which is mounted outside the rotating bearing 22. The rotating bearing 22 is connected to the first gear 21 via the bearing retainer 23. It will be appreciated that the bearing retainer 23 is mounted outside the rotating bearing 22, thereby facilitating the bearing retainer 23 to provide fixation and support for the rotating bearing 22, absorbing radial loads borne by the rotating bearing 22, and thereby protecting the rotating bearing 22. The rotating bearing 22 is connected to the first gear 21 via the bearing retainer 23, thereby improving the stability of the connection between the rotating bearing 22 and the first gear 21. Thus, the bearing retainer 23 provides support and fixation for the rotating bearing 22, improving the stability of the connection between the rotating bearing 22 and the first gear 21.

[0054] In some embodiments, the drive assembly 10 includes a drive motor 11 and a power dispersion wheel 12. The power dispersion wheel 12 is connected to the output end of the drive motor 11, and the first transmission wheel 20 and the second transmission wheel 30 are respectively connected to the power dispersion wheel 12. The drive motor 11 can serve as a power source and is used to output power. The power dispersion wheel 12 is connected to the output end of the drive motor 11. It is understood that the power dispersion wheel 12 can transmit the power output by the drive motor 11 to the first transmission wheel 20 and the second transmission wheel 30 respectively, so that the drive motor 11 can drive the first transmission wheel 20 and the second transmission wheel 30 respectively, thereby causing the first transmission wheel 20 and the second transmission wheel 30 to rotate independently of each other around the first axis x1. Thus, the power dispersion wheel 12 can transmit the power output by the drive motor 11 to the first transmission wheel 20 and the second transmission wheel 30 respectively, so that the drive motor 11 can simultaneously drive the first transmission wheel 20 and the second transmission wheel 30 to rotate independently of each other around the first axis x1. This eliminates the need to provide multiple power sources to drive the first transmission wheel 20 and the second transmission wheel 30 separately, thereby reducing the size of the cleaning device 1 and saving production costs.

[0055] In some embodiments, the first transmission wheel 20 includes a first gear 21, the second transmission wheel 30 includes a second gear 31, and the power dispersion wheel 12 includes a third gear 121 and a fourth gear 122. The third gear 121 and the fourth gear 122 are spaced apart, the first gear 21 and the third gear 121 are meshed, and the second gear 31 and the fourth gear 122 are meshed. It is understood that the third gear 121 can transmit part of the power output by the drive motor 11 to the first gear 21 through a meshing connection, and the fourth gear 122 can transmit part of the power output by the drive motor 11 to the second gear 31 through a meshing connection, thereby distributing the power output by the drive motor 11 to the first gear 21 and the second gear 31. Specifically, the first gear 21 can drive the transmission rod 41 to rotate about the first axis x1, and the second gear 31 can drive the transmission rod 41 to rotate about the second axis x2. Thus, the first gear 21 can be driven to rotate around the first axis x1 by the third gear 121, and the second gear 31 can be driven to rotate around the first axis x1 by the fourth gear 122, so that the driving motor 11 can simultaneously drive the first gear 21 and the second gear 31 to rotate around the first axis x1 independently of each other, without setting up multiple power sources to drive the first gear 21 and the second gear 31 respectively, thereby reducing the volume of the cleaning device 1 and saving production costs.

[0056] In some embodiments, the ratio of the self-rotation speed to the orbital speed of the transmission rod 41 is inversely proportional to the gear ratio between the first gear 21 and the third gear 121. For example, the ratio of the self-rotation speed to the orbital speed of the transmission rod 41 can be reduced by increasing the gear ratio between the first gear 21 and the third gear 121, or the ratio of the self-rotation speed to the orbital speed of the transmission rod 41 can be increased by decreasing the gear ratio between the first gear 21 and the third gear 121.

[0057] In some embodiments, the ratio of the self-rotation speed to the orbital speed of the transmission rod 41 is proportional to the gear ratio between the second gear 31 and the fourth gear 122. For example, the ratio of the self-rotation speed to the orbital speed of the transmission rod 41 can be increased by increasing the gear ratio between the second gear 31 and the fourth gear 122, or reduced by decreasing the gear ratio between the second gear 31 and the fourth gear 122.

[0058] In some embodiments, the ratio of the self-rotation speed and the orbital speed of the transmission rod 41 is inversely proportional to the gear ratio of the first gear 21 and the third gear 121, and the ratio of the self-rotation speed and the orbital speed of the transmission rod 41 is directly proportional to the gear ratio of the second gear 31 and the fourth gear 122. For example, when the gear ratios of the second gear 31 and the fourth gear 122 are the same, the ratio of the self-rotation speed and the orbital speed of the transmission rod 41 can be increased by reducing the gear ratio of the first gear 21 and the third gear 121. Alternatively, when the gear ratios of the first gear 21 and the third gear 121 are the same, the ratio of the self-rotation speed and the orbital speed of the transmission rod 41 can be increased by increasing the gear ratio of the second gear 31 and the fourth gear 122. Among them, the specific gear ratios of the first gear 21 and the third gear 121 and the gear ratios of the second gear 31 and the fourth gear 122 can be set according to the actual layout space and cleaning requirements. Therefore, the ratio of the rotation speed and the revolution speed of the transmission rod 41 can be adjusted by adjusting the gear ratio of the first gear 21 and the third gear 121 or adjusting the gear ratio of the second gear 31 and the fourth gear 122, which helps to flexibly adjust the rotation speed of the transmission rod 41, thereby improving the cleaning effect.

[0059] In some embodiments, the ratio of the self-rotation speed to the orbital speed of the transmission rod 41 is between 1 and 30. For example, the ratio of the self-rotation speed to the orbital speed of the transmission rod 41 can be between 1 and 15, or between 10 and 20, or between 20 and 30. Specifically, the ratio of the self-rotation speed to the orbital speed of the transmission rod 41 can include but is not limited to 1, 5, 8, 10, 15, 20 or 30, etc. Thus, by setting the ratio of the self-rotation speed to the orbital speed of the transmission rod 41 between 1 and 30, the self-rotation speed and the orbital speed of the transmission rod 41 can be more flexibly matched with actual cleaning needs, thereby improving the cleaning effect.

[0060] In some embodiments, the cleaning device 1 includes a hollow tube 43, which is provided with a housing cavity 431 extending along the first axis x1, the transmission rod 41 is at least partially located in the housing cavity 431, and the cleaning portion 42 is at least partially located outside the housing cavity 431. It can be understood that the hollow tube 43 forms a housing cavity 431 to accommodate at least a portion of the transmission rod 41, and the end of the hollow tube 43 may have an opening, so as to facilitate at least a portion of the cleaning portion 42 to extend out of the hollow tube 43 through the opening. Specifically, the transmission rod 41 may be partially located in the housing cavity 431 and partially extend out of the housing cavity 431 through the opening, or the transmission rod 41 may be completely located in the housing cavity 431 and a portion of the cleaning portion 42 extends out of the housing cavity 431 through the opening, or the transmission rod 41 may be completely located in the housing cavity 431 and the cleaning portion 42 extends out of the housing cavity 431 through the opening, or the transmission rod 41 may be completely located in the housing cavity 431 and the cleaning portion 42 extends entirely out of the housing cavity 431 through the opening. It should be noted that the accommodating cavity 431 extends along the first axis x1 and provides sufficient space to allow the transmission rod 41 to revolve around the first axis x1 within the accommodating cavity 431. Thus, the accommodating cavity 431 can accommodate at least a portion of the transmission rod 41, allowing the hollow tube 43 to provide protection for the transmission rod 41 and reduce the risk of damage to the transmission rod 41. At the same time, the cleaning portion 42 is at least partially located outside the accommodating cavity 431, facilitating cleaning of the area to be cleaned outside the hollow tube 43 by the cleaning portion 42.

[0061] In some embodiments, the hollow tube 43 is provided with at least one adsorption port 432, and the adsorption port 432 is connected to the accommodating chamber 431. It is understandable that the accommodating chamber 431 can be sucked through the adsorption port 432 to form a negative pressure area in the accommodating chamber 431, so that the impurity particles cleaned by the cleaning portion 42 enter the hollow tube 43 through the opening of the hollow tube 43 under the action of negative pressure and are adsorbed by the adsorption port 432. Exemplarily, the adsorption port 432 can be connected to an air suction device, so that the air suction device can evacuate the accommodating chamber 431 through the adsorption port 432. Thus, a negative pressure area can be formed inside the accommodating chamber 431 through the adsorption port 432 to adsorb the impurity particles cleaned by the cleaning portion 42, thereby effectively collecting the impurity particles and alleviating the risk of impurity particles being scattered to other areas due to failure to be collected in time.

[0062] In some embodiments, the cleaning portion 42 extends along the second axis x2. It is understandable that the cleaning portion 42 extends along the second axis x2, so that the transmission rod 41 drives the cleaning portion 42 to rotate around the first axis x1 when it revolves around the first axis x1, and at the same time, it drives the cleaning portion 42 to rotate around the second axis x2 when the transmission rod 41 rotates around the second axis x2. Furthermore, the cleaning portion 42 extends along the second axis x2, which also helps the cleaning portion 42 contact the area to be cleaned along the second axis x2, thereby cleaning the clean area. In some application scenarios, the cleaning portion 42 can also extend in a radial direction perpendicular to the second axis x2. Specifically, taking the cleaning portion 42 as a brush as an example, the brush can have multiple bristles, and the multiple bristles can be arranged in a radial direction in a straight line, so that when the cleaning portion 42 revolves around the first axis x1 and rotates around the second axis x2, the cleaning portion 42 can contact the area to be cleaned more fully, thereby improving the cleaning effect. Therefore, the cleaning portion 42 can be extended along the second axis x2 so that the cleaning portion 42 can simultaneously rotate and revolve under the drive of the transmission rod 41, thereby increasing the cleaning range of the cleaning portion 42 and improving the cleaning effect.

[0063] In some embodiments, the cleaning device 1 further includes a reversing wheel 50, through which the second transmission wheel 30 is connected to the drive assembly 10, and the reversing wheel 50 is configured to drive the second transmission wheel 30 to rotate in the opposite direction to the first transmission wheel 20. For example, in some application scenarios, the drive assembly 10 can output power via a drive shaft. When viewed from the side of the first transmission wheel 20 facing away from the second transmission wheel 30 and along the first axis x1, the drive shaft can rotate clockwise, the first transmission wheel 20 can rotate counterclockwise under the drive shaft, the reversing wheel 50 can also rotate counterclockwise under the drive shaft, and the second transmission wheel 30 can be meshed with the reversing wheel 50, so that the second transmission wheel 30 rotates clockwise under the drive of the reversing wheel 50. Thus, by causing the second transmission wheel 30 to rotate in the opposite direction to the first transmission wheel 20 through the reversing wheel 50, the ratio of the rotational speed to the orbital speed of the transmission rod 41 can be increased, thereby improving the cleaning effect. In some other embodiments, the first transmission wheel 20 may include a first gear 21, the second transmission wheel 30 may include a second gear 31, the second gear 31 may be connected to the drive assembly 10 through a reversing wheel 50, the reversing wheel 50 may drive the second gear 31 to rotate in a direction opposite to the first gear 21, the first gear 21 may drive the transmission rod 41 to rotate around the first axis x1, and the second gear 31 may drive the transmission rod 41 to rotate around the second axis x2. Furthermore, in some application scenarios, the second transmission wheel 30 includes a second gear 31, the second gear 31 is provided with a second through hole 310, and the inner side wall of the second through hole 310 is provided with an internal tooth 311, and the transmission rod 41 is passed through the second through hole 310, and the transmission rod 41 is provided with an external tooth 411 at a position corresponding to the internal tooth 311, and the internal tooth 311 and the external tooth 411 are engaged. When the rotation direction of the first transmission wheel 20 is opposite to the rotation direction of the second gear 31, the second gear 31 can also be engaged with the external tooth 411 of the transmission rod 41 through the internal tooth 311, so that the direction of rotation of the transmission rod 41 around the second axis x2 is the same as the rotation direction of the second gear 31, thereby driving the transmission rod 41 to rotate in the opposite direction to the revolution direction of the transmission rod 41 around the first axis x1. In some other embodiments, the drive assembly 10 may further include a power dispersion wheel 12, which includes a third gear 121 and a fourth gear 122. The third gear 121 and the fourth gear 122 are arranged at intervals, the third gear 121 is engaged with the first gear 21, and the reversing wheel 50 is engaged with the fourth gear 122 and the second gear 31 respectively. It can be understood that the third gear 121 and the fourth gear 122 have the same rotation direction, the first gear 21 and the reversing wheel 50 have the same rotation direction, and the second gear 31 and the reversing wheel 50 have different rotation directions, so that the reversing wheel 50 can be used to make the second gear 31 rotate in the opposite direction to the first gear 21.

[0064] Please refer to Figure 5-Figure 7 , Figure 5is a fourth structural schematic diagram of a cleaning device according to one or more embodiments of the present application; Figure 6 is based on Figure 5 The cleaning device shown is a schematic cross-sectional view along the AA direction; Figure 7 is based on Figure 5 The cleaning device shown is a schematic cross-sectional view along direction BB.

[0065] The rotating bearing 22 is located on the side of the first gear 21 facing away from the second transmission wheel 30. The first gear 21 is provided with a first through-hole 211, and the transmission rod 41 is inserted into the rotating bearing 22 through the first through-hole 211. It is understood that the transmission rod 41 can be inserted into the rotating bearing 22 through the first through-hole 211, so that when the transmission rod 41 rotates about the first axis x1 driven by the first gear 21, the friction between the first gear 21 and the transmission rod 41 is reduced by the rotating bearing 22, thereby facilitating relative rotation between the first gear 21 and the transmission rod 41. In some application scenarios, the transmission rod 41 is spaced apart from the sidewall of the first through-hole 211, so that the first through-hole 211 can provide sufficient space for the transmission rod 41 to rotate, thereby reducing the risk of interference between the transmission rod 41 and the first gear 21 during its rotation about the second axis x2. Thus, by having the transmission rod 41 pass through the first through hole 211 and be inserted into the rotating bearing 22, the transmission rod 41 is connected to the first gear 21, thereby improving the stability of the first gear 21 driving the transmission rod 41 to rotate about the first axis x1, and at the same time facilitating the rotating bearing 22 to provide support for the transmission rod 41. In other embodiments, the rotating bearing 22 may also be located on the side of the first gear 21 facing the second transmission wheel 30.

[0066] In some embodiments, the second transmission wheel 30 includes a second gear 31, the second gear 31 is provided with a second through hole 310, the inner side wall of the second through hole 310 is provided with internal teeth 311, and a transmission rod 41 is provided through the second through hole 310. The transmission rod 41 is provided with external teeth 411 at positions corresponding to the internal teeth 311, and the internal teeth 311 and the external teeth 411 are meshed. It is understood that when the drive assembly 10 drives the second gear 31 to rotate about the first axis x1, the internal teeth 311 on the inner side wall of the second through hole 310 also rotate about the first axis x1, and the transmission rod 41 is also driven by the first gear 21 to rotate about the first axis x1. Therefore, when the transmission rod 41 rotates about the first axis x1, the second gear 31, through the meshing of the internal teeth 311 and the external teeth 411, drives the transmission rod 41 to rotate about the second axis x2 on which it is located. Thus, the meshing of the external teeth 411 on the transmission rod 41 with the internal teeth 311 on the inner wall of the second through hole 310 facilitates the second gear 31 to drive the transmission rod 41 to rotate about its own second axis x2 during its rotation about the first axis x1, thereby improving the stability of the transmission rod 41's rotation about the second axis x2. In some applications, the second transmission wheel 30 further includes bearings. The bearings can be disposed on both the side of the second gear 31 facing the first transmission wheel 20 and the side of the second gear 31 facing away from the first transmission wheel 20. The transmission rod 41 is inserted into the bearings, thereby facilitating the bearings to provide support for the transmission rod 41 and reducing rotational friction of the transmission rod 41.

[0067] In some embodiments, the ratio of the self-rotation speed and the orbital speed of the transmission rod 41 is proportional to the gear ratio of the inner teeth 311 and the outer teeth 411. For example, the ratio of the self-rotation speed and the orbital speed of the transmission rod 41 can be increased by increasing the gear ratio of the inner teeth 311 and the outer teeth 411, or the ratio of the self-rotation speed and the orbital speed of the transmission rod 41 can be increased by reducing the gear ratio of the inner teeth 311 and the outer teeth 411. Among them, the specific gear ratio of the inner teeth 311 and the outer teeth 411 can be set according to the actual speed requirement. Thus, the ratio of the self-rotation speed and the orbital speed of the transmission rod 41 can be adjusted by adjusting the gear ratio of the inner teeth 311 and the outer teeth 411, which helps to flexibly adjust the speed of the transmission rod 41, thereby improving the cleaning effect.

[0068] To summarize, the cleaning device 1 provided in the present application includes a drive assembly 10, a first transmission wheel 20, a second transmission wheel 30 and a cleaning member 40.

Thus, the first transmission wheel 20 and the second transmission wheel 30 can be driven by the drive assembly 10 to rotate around the first axis x1, and the transmission rod 41 of the cleaning member 40 extends along the second axis x2 and is connected to the first transmission wheel 20 and the second transmission wheel 30 respectively, so that the first transmission wheel 20 drives the transmission rod 41 to revolve around the first axis x1, and the second transmission wheel 30 drives the transmission rod 41 to rotate around the second axis x2, so that the cleaning member 40 can revolve and rotate simultaneously, thereby increasing the cleaning range of the cleaning member 40, reducing the cleaning blind spot, and improving the cleaning effect. Compared with other types of cleaning devices, the cleaning device 1 of the present application has a larger cleaning range and better cleaning effect.
