Description

Technical Field

[0001] This application relates to the field of cleaning equipment, and more particularly to a water tank and cleaning equipment. Background Technology

[0002] With the development of technology, cleaning equipment has shifted from manual tools to automation. Taking floor scrubbers as an example, automated cleaning equipment can automatically sweep, scrub, dry, intelligently avoid obstacles, adjust suction power, and perform one-button self-cleaning. The emergence of floor scrubbers has significantly reduced manpower and improved cleaning efficiency.

[0003] In related technologies, the wastewater tank in floor scrubbers does not have an automatic cleaning function and requires frequent manual cleaning.

[0004] However, frequent manual cleaning of the wastewater tank is inefficient and results in a poor user experience. Utility Model Content

[0005] This application provides a water tank and a cleaning device. It solves the problem that water tanks in the prior art cannot achieve self-cleaning. The technical solution is as follows:

[0006] In a first aspect, a water tank is provided, comprising: a base, a drive assembly, a transmission assembly, and a water tank body;

[0007] The drive assembly is fixed to the first support surface of the base;

[0008] The transmission assembly includes: a first transmission rod and at least two second transmission rods; the middle position of the first transmission rod is connected to the drive assembly; one end of each of the second transmission rods is fixedly connected to the first transmission rod, and the other end is fixedly connected to the outer wall of the water tank body.

[0009] The drive assembly is configured to drive the first transmission rod to rotate eccentrically, thereby driving the water tank body to rotate eccentrically via the at least two second transmission rods.

[0010] Because the middle position of the first transmission rod is connected to the drive assembly fixed to the first support surface of the base, and one end of each of the second transmission rods is fixedly connected to the first transmission rod, and the other end is fixedly connected to the outer wall of the water tank body, the drive assembly can drive the first transmission rod to rotate eccentrically, and through the second transmission rods, drive the water tank body to rotate eccentrically. In this way, the water tank body rotates as a whole, and correspondingly, the water inside the water tank body also rotates along the entire inner wall of the water tank body, and the water rotation within the water tank body is relatively uniform. By the relatively uniform rotation of the water within the water tank body along the entire inner wall of the water tank body, the entire inner wall of the water tank body can be flushed and cleaned. This achieves automatic cleaning of the water tank and avoids the accumulation of dirt in the corners and edges of the water tank body, improving the cleaning effect and efficiency of the water tank.

[0011] Furthermore, the water tank in this application does not require a cleaning component to be placed inside the water tank body when it performs self-cleaning, which allows the water tank body to be smaller and achieves a miniaturized design.

[0012] Furthermore, since no cleaning components need to be placed inside the water tank, the internal structure of the water tank is simple, easy to design and implement, and can be adapted to more types or models of water tanks.

[0013] In addition, the drive component in the water tank is indirectly connected to the outer wall of the water tank body through the transmission component and performs eccentric drive, which can reduce the size of the water tank on both the perpendicular and parallel surfaces of the first support surface, which helps to achieve the miniaturization of the water tank and the rational spatial layout.

[0014] In some possible implementations, the drive assembly includes: a drive motor and an eccentric wheel;

[0015] The output shaft of the drive motor is connected to the eccentric wheel, and the eccentric wheel has a first connecting shaft on the side away from the drive motor. The first connecting shaft is rotatably connected to the middle position of the first transmission rod.

[0016] The centerline of the output shaft of the drive motor does not coincide with the centerline of the first connecting shaft.

[0017] The output shaft of the drive motor is connected to an eccentric wheel. The eccentric wheel has a first connecting shaft on the side facing away from the drive motor. This first connecting shaft is rotatably connected to the middle position of the first transmission rod, and the centerline of the drive motor's output shaft does not coincide with the centerline of the first connecting shaft. This allows the first transmission rod to rotate eccentrically, and at least two second transmission rods can drive the water tank body to rotate eccentrically. When the water tank body can rotate eccentrically relative to the output shaft of the drive motor, the spatial size requirements of the water tank body during rotation can be reduced, thus facilitating the miniaturization and compactness of the water tank.

[0018] In some possible implementations, the eccentric wheel includes: an eccentric wheel body and the first connecting shaft;

[0019] The eccentric wheel body is connected to the output shaft of the drive motor, and the side of the eccentric wheel body facing away from the drive motor is connected to one end of the first connecting shaft.

[0020] The centerline of the eccentric wheel body coincides with the centerline of the output shaft of the drive motor, but does not coincide with the centerline of the first connecting shaft.

[0021] The eccentric wheel body is connected to the output shaft of the drive motor, and the side of the eccentric wheel body facing away from the drive motor is connected to one end of the first connecting shaft. By aligning the eccentric wheel body with the axis of the drive motor's output shaft, it is easier to achieve power transmission from the drive motor to the eccentric wheel, thereby better driving the water tank body to rotate. By using the first connecting shaft, which is not aligned with the axis of the drive motor's output shaft, eccentric rotation of the water tank body can be achieved, thus improving the space utilization of the water tank.

[0022] In some possible implementations, the drive assembly further includes: a bracket fixed to the first support surface; in a third direction perpendicular to the first support surface, the drive motor is located between the bracket and the first support surface, and the bracket has a shaft hole;

[0023] At least a portion of the eccentric wheel body is rotatably connected to the bracket within the shaft hole.

[0024] The shaft hole on the bracket can provide some support for the eccentric wheel body, and can also indirectly provide some support for the transmission components and the water tank body, thereby ensuring that the water tank body can rotate smoothly.

[0025] In some possible implementations, the water tank further includes a support assembly located between the water tank body and the first support surface; one side of the support assembly is fixedly connected to the first support surface, and the other side is movably connected to the water tank body.

[0026] The water tank body is supported by the support components, ensuring that the water tank body can rotate smoothly under the action of the drive components and transmission components.

[0027] In some possible implementations, the support assembly includes: at least two support columns spaced apart; and at least two sleeve portions on the outer wall of the water tank body.

[0028] The at least two support columns and the at least two sleeve portions correspond one-to-one. Each sleeve portion is sleeved on the end of the corresponding support column that is away from the first support surface and is rotatably connected to the corresponding support column.

[0029] By rotating the sleeve on the water tank body and the end of the support column, the water tank body can be supported without interfering with its rotation. Furthermore, the connection between the support column and the sleeve on the outer wall of the water tank body reduces the height of the support column in the third direction, thus enabling the water tank to be miniaturized and compacted.

[0030] In some possible implementations, each of the support columns includes: a first column and a second column distributed along the axial direction; one end of the first column is fixedly connected to the first support surface, and the other end of the first column is fixedly connected to one end of the second column; the radial dimension of the first column is larger than the radial dimension of the second column;

[0031] Each of the said sockets has a socket hole, and the socket is sleeved onto the second column through the socket hole;

[0032] The radial dimension of the socket is greater than the radial dimension of the second column and less than the radial dimension of the first column.

[0033] The first column, which has a relatively larger radial dimension, can provide sufficient support, while the second column, which has a relatively smaller radial dimension, can be used to connect with the sleeve part.

[0034] In some possible implementations, the end face of the sleeve facing the first support surface contacts the end of the first column away from the first support surface; the inner wall of the sleeve contacts the outer wall of the second column.

[0035] By having the end face of the sleeve facing the first support surface contact the end of the first column opposite to the first support surface, sufficient support force can be provided to the water tank body. Furthermore, the contact between the inner wall of the sleeve and the outer wall of the second column ensures that, during the rotation of the sleeve relative to the second column, the second column can always provide radial support and limit to the water tank body, thereby ensuring that the water tank body can rotate relatively accurately along a preset trajectory.

[0036] In some possible implementations, the water tank body includes: a water tank section, and a buffer sleeve fitted onto the outside of the water tank section; the buffer sleeve has the connecting portion on its outer side away from the water tank section, and the connecting portion and the buffer sleeve are integrally molded structures made of elastic material.

[0037] By using a one-piece sleeve and buffer sleeve made of elastic material, the vibration of the water in the tank that is transferred to the base side due to rotation can be absorbed and buffered, thereby achieving the effects of vibration reduction and noise reduction.

[0038] In some possible implementations, the outer wall of the water tank section has at least two connecting portions; the buffer sleeve has at least two clearance openings corresponding one-to-one with the at least two connecting portions, and each connecting portion extends out of the buffer sleeve through the corresponding clearance opening.

[0039] The at least two connecting parts correspond one-to-one with the at least two second transmission rods, and each connecting part is fixedly connected to the end of the corresponding second transmission rod that is away from the first transmission rod.

[0040] The connecting part facilitates a fixed connection between the second transmission rod and the water tank.

[0041] In some possible implementations, the support assembly further includes: at least two elastic buffers; the at least two elastic buffers are located between the at least two support columns and between the first support surface and the water tank body;

[0042] In this configuration, one end of each elastic buffer abuts against the first support surface, and the other end abuts against the side of the water tank body facing the first support surface.

[0043] The elastic buffer can not only provide support for the water tank body, but also absorb and buffer the vibration of the water in the water tank body that is transferred to the base side due to rotation, thereby achieving the effects of vibration reduction and noise reduction.

[0044] In some possible implementations, the support assembly includes: a support platform and at least two support legs;

[0045] The at least two support legs are located between the support platform and the first support surface, with one side of each support leg connected to the first support surface and the other side connected to one side of the support platform.

[0046] The water tank body is located on the side of the support platform away from the first support surface, and the water tank body is slidably connected to the support platform.

[0047] The support platform provides sufficient support surface for the water tank, thus ensuring effective support. Furthermore, the support platform, in conjunction with at least two support legs, provides even better support for the water tank.

[0048] In some possible implementations, at least a portion of the first transmission rod is located on the side of the bracket in the drive assembly opposite to the first support surface; the water tank further includes a limiting assembly located at least on the side of the first transmission rod opposite to the bracket, and the limiting assembly is movably connected to the bracket;

[0049] The limiting component is used to restrict the movement of the first transmission rod in a third direction perpendicular to the first support surface.

[0050] By using a limiting component that is movably connected to the bracket, the movement of the first transmission rod in a third direction perpendicular to the first support surface is restricted, which in turn restricts the position of the water tank body in the third direction. This reduces the vibration and noise generated by the movement of the water tank body in the third direction. This also better ensures that the water tank body can rotate smoothly.

[0051] In some possible implementations, the bracket extends entirely along a first direction; the limiting assembly includes: a pressure plate, a second connecting shaft, and two sliders;

[0052] The two sliders are arranged opposite each other in the second direction, and the sliders are slidably connected to the bracket in the first direction; the second direction intersects the first direction and is parallel to the first support surface;

[0053] The two ends of the second connecting shaft are respectively connected to the two sliders;

[0054] The pressure plate is fixed on the side of the first transmission rod away from the bracket, and the pressure plate is slidably connected to the second connecting shaft in the second direction;

[0055] In the third direction, the second connecting shaft is located on the side of the first transmission rod away from the bracket.

[0056] Since the first transmission rod and the pressure plate in the transmission assembly are fixedly connected, and the pressure plate is slidably connected to the second connecting shaft in the second direction, and the slider connected to the second connecting shaft can be slidably connected to the bracket in the first direction, the first transmission rod can perform compound motion in the first and second directions under the drive of the drive assembly, thereby achieving eccentric rotation.

[0057] Furthermore, in the third direction, the first transmission rod is located between the pressure plate and the bracket. This restricts the position of the first transmission rod, the second transmission rod, and the water tank body in the third direction, thereby reducing the amount of vibration that the water tank body brings to the internal components of the water tank.

[0058] Furthermore, this type of limiting component is easy to implement and has high reliability and feasibility.

[0059] In some possible implementations, the tablet has a through hole extending in the second direction; a portion of the second connecting shaft is fitted into the through hole, and the second connecting shaft is slidably connected to the tablet through the through hole.

[0060] The second connecting shaft is slidably connected to the pressure plate through a through hole, which facilitates more accurate restriction of the position of the first transmission rod in the third direction. For example, the diameter of the through hole is the same as the diameter of the second connecting shaft, or the diameter of the through hole is slightly larger than the diameter of the connecting shaft.

[0061] In some possible implementations, both the first transmission rod and the bracket extend along a first direction; in the first direction, the length of the first transmission rod is greater than the length of the bracket, and the two ends of the first transmission rod are located on the outside of the bracket, respectively.

[0062] In the second direction, the width of the first transmission rod is smaller than the width of the bracket;

[0063] There are two second transmission rods, which are located at the two ends of the first transmission rod in the first direction. The second direction intersects the first direction and is parallel to the first support surface.

[0064] Both the first transmission rod and the bracket extend along a first direction. In the first direction, the length of the first transmission rod is greater than the length of the bracket, and the two ends of the first transmission rod are located on the outside of the bracket. This not only enables the bracket to support the first transmission rod, but also reduces the size, weight, and cost of the bracket, and reduces the space occupied by the bracket, thereby freeing up more space for flexible layout of the structure inside the water tank.

[0065] By making the width of the first transmission rod smaller than the width of the bracket in the second direction, the first transmission rod has sufficient room to move relative to the bracket in the second direction.

[0066] The two second drive rods are located at opposite ends of the first drive rod in the first direction. This avoids interference between the support and the second drive rods, allowing for a more rational internal space design for the water tank.

[0067] In a second aspect, a cleaning device is provided, comprising: a water tank as described in any of the above. Attached Figure Description

[0078] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0079] Cleaning equipment typically includes a water tank, such as a clean water tank for fresh water or a wastewater tank for wastewater. Since the water tanks in cleaning equipment lack automatic cleaning functions, users need to manually clean the inner walls of the tanks. Wastewater tanks, in particular, require frequent cleaning because they store wastewater. This frequent cleaning adds to the user's workload and reduces their overall experience with the cleaning equipment.

[0080] To address the issue of water tanks not being able to clean themselves, taking sewage tanks as an example, a proposed solution involves placing spiral blades inside the sewage tank. The spiral blades rotate and agitate the sewage inside the tank to achieve a cleaning effect.

[0081] However, while installing spiral blades inside the sewage tank can clean the inner walls, the cleaning effect is limited. For example, the spiral blades cause uneven water flow during rotation, resulting in slow flow at the corners and edges of the tank, where dirt tends to accumulate.

[0082] Based on this, this application provides a water tank and a cleaning device including the water tank, which can realize automatic cleaning of the water tank and improve the cleaning effect of the water tank.

[0083] Figure 1 This is a schematic diagram of the structure of a water tank provided in an embodiment of this application. Please refer to it. Figure 1 In one embodiment of this application, a water tank 000 is provided, including: a base 010, a drive assembly 020, a transmission assembly 030, and a water tank body 040.

[0084] The drive component 020 is fixed on the first support surface M1 of the base 010.

[0085] The transmission assembly 030 includes a first transmission rod 031 and at least two second transmission rods 032. The middle position of the first transmission rod 031 is connected to the drive assembly 020. One end of each of the second transmission rods 032 is fixedly connected to the first transmission rod 031, and the other end is fixedly connected to the outer wall of the water tank body 040.

[0086] The drive assembly 020 is configured to drive the first transmission rod 031 to rotate eccentrically, thereby driving the water tank body 040 to rotate eccentrically via at least two second transmission rods 032.

[0087] For example, the output shaft of the drive assembly 020 is fixedly connected to the first transmission rod 031. Thus, by rotating the output shaft in the drive assembly 020, the first transmission rod 031, the second transmission rod 032, and the water tank body 040 can be driven to rotate.

[0088] Among them, the first transmission rod 031 and the second transmission rod 032 located between the output shaft of the drive assembly 020 and the water tank body 040 are similar to transmission arms, realizing the transmission of the output shaft of the drive assembly 020 to one side of the water tank body 040, and driving the water tank body 040 to rotate.

[0089] It should be noted that eccentric rotation of the first transmission rod 031 means that the axis of rotation of the first transmission rod 031 is offset from the axis of rotation of the output shaft of the drive assembly 020, that is, the axis of rotation of the first transmission rod 031 does not coincide with the axis of rotation of the output shaft of the drive assembly 020. Similarly, when the water tank body 040 rotates eccentrically, the axis of rotation of the water tank body 040 is offset from or does not coincide with the axis of rotation of the output shaft of the drive assembly 020. Taking the first transmission rod 031 as an example, the axis of rotation of the first transmission rod 031 refers to the axis corresponding to the rotation trajectory of the first transmission rod 031 during rotation.

[0090] In summary, because the middle position of the first transmission rod is connected to the drive assembly fixed to the first support surface of the base, and one end of each of the second transmission rods is fixedly connected to the first transmission rod, while the other end is fixedly connected to the outer wall of the water tank body, the drive assembly can drive the first transmission rod to rotate eccentrically, and through the second transmission rods, drive the water tank body to rotate eccentrically. Thus, when the water tank body rotates, the entire body rotates, and correspondingly, the water inside the water tank body also rotates along the entire inner wall of the water tank body, and the water rotation within the water tank body is relatively uniform. By the relatively uniform rotation of the water within the water tank body along the entire inner wall of the water tank body, the entire inner wall of the water tank body can be flushed and cleaned. This achieves automatic cleaning of the water tank and avoids the accumulation of dirt in the corners and edges of the water tank body, improving the cleaning effect and efficiency of the water tank.

[0091] Furthermore, the water tank in this application does not require a cleaning component to be placed inside the water tank body when it performs self-cleaning, which allows the water tank body to be smaller and achieves a miniaturized design.

[0092] Furthermore, since no cleaning components need to be placed inside the water tank, the internal structure of the water tank is simple, easy to design and implement, and can be adapted to more types or models of water tanks.

[0093] In addition, the drive component in the water tank is indirectly connected to the outer wall of the water tank body through the transmission component and performs eccentric drive, which can reduce the size of the water tank on both the perpendicular and parallel surfaces of the first support surface, which helps to achieve the miniaturization of the water tank and the rational spatial layout.

[0094] It should be noted that when the water tank 000 is in use, the base 010 is usually located at the bottom. If the height space requirement is not considered, in other possible implementations, the drive component 020 can also be directly placed between the water tank body 040 and the base 010. The output shaft of the drive component 020 is directly fixedly connected to the bottom of the water tank body 040 and drives it.

[0095] Taking the application of the water tank 000 in the above embodiment to a floor scrubber as an example, the thickness or height of the floor scrubber is relatively low to avoid the floor scrubber occupying too much height space, but the floor scrubber has slightly more space in the radial direction. By setting the water tank 000 in the radial direction of the floor scrubber, the space inside the floor scrubber can be fully utilized, and the height can be saved.

[0096] Figure 2 This is a schematic diagram of another water tank structure provided in an embodiment of this application. Please refer to it. Figure 2 In some possible implementations, the drive component 020 includes a drive motor 021 and an eccentric wheel 022.

[0097] The output shaft 0211 of the drive motor 021 is connected to the eccentric wheel 022. The eccentric wheel 022 has a first connecting shaft 0221 on the side away from the drive motor 021. The first connecting shaft 0221 is rotatably connected to the middle position of the first transmission rod 031.

[0098] The centerline of the output shaft 0211 of the drive motor 021 does not coincide with the centerline of the first connecting shaft 0221.

[0099] The output shaft 0211 of the drive motor 021 is connected to the eccentric wheel 022. The eccentric wheel 022 has a first connecting shaft 0221 on the side opposite to the drive motor 021. The first connecting shaft 0221 is rotatably connected to the middle position of the first transmission rod 031, and the axis of the output shaft 0211 of the drive motor 021 does not coincide with the axis of the first connecting shaft 0221, allowing the first transmission rod 031 to rotate eccentrically. Furthermore, at least two second transmission rods 032 can drive the water tank body 040 to rotate eccentrically. When the water tank body 040 can rotate eccentrically relative to the output shaft 0211 of the drive motor 021, the spatial size requirements of the water tank body 040 during rotation can be reduced, thereby facilitating the miniaturization and compactness of the water tank 000.

[0100] In this embodiment, the number of second transmission rods 032 can be two, three, four, etc., which can be set according to the specific needs.

[0101] For example, the number of second transmission rods 032 in the transmission assembly 030 is configured to be two. Please refer to [reference needed]. Figure 3 , Figure 3 This is a schematic diagram of a transmission assembly provided in an embodiment of this application. The first transmission rod 031 extends in a first direction, and the second transmission rod 032 extends in a second direction.

[0102] Two second transmission rods 032 are distributed on both sides of the first transmission rod 031 in the first direction, and the two second transmission rods 032 are located on the side of the first transmission rod 031 closer to the water tank body 040 in the second direction.

[0103] The transmission assembly 030 further includes an adapter 033, which is located on the side of the first transmission rod 031 facing away from the water tank body 040 in the second direction, and the adapter 033 is located at the middle position of the first transmission rod 031 in the first direction. The adapter 033 is movably connected to the first connecting shaft 0221.

[0104] The first direction and the second direction intersect, and both the first direction and the second direction can be parallel to the first support surface M1 on the base 010. The adapter 033 is similar to a plate that protrudes outward relative to the first transmission rod 031 in the second direction, and the first transmission rod 031, the second transmission rod 032 and the adapter 033 are an integral plate structure, which can be parallel to the first support surface M1.

[0105] By connecting the adapter 033 and the first connecting shaft 0221, the size of the first transmission rod 031 in the second direction can be reduced, and the adapter 033 has a smaller size relative to the first transmission rod 031 in the first direction. In this way, interference between the transmission assembly 030 and other components in the water tank 000 can be avoided.

[0106] Furthermore, the adapter 033 and the first connecting shaft 0221 are movably connected, that is, the first connecting shaft 0221 is indirectly movably connected to the first transmission rod 031 through the adapter 033. In this way, when the first connecting shaft 0221 drives the transmission component 030 to rotate, the adapter 033 and the transmission component 030 can be adaptively adjusted in position to ensure the smooth rotation of the water tank body 040.

[0107] Figure 4 This is a schematic diagram of the structure of an eccentric wheel provided in an embodiment of this application. Please refer to it. Figure 4 In one possible implementation, the eccentric wheel 022 includes: an eccentric wheel body 0222 and a first connecting shaft 0221.

[0108] The eccentric wheel body 0222 is connected to the output shaft 0211 of the drive motor 021, and the side of the eccentric wheel body 0222 facing away from the drive motor 021 is connected to one end of the first connecting shaft 0221.

[0109] The axis of the eccentric wheel body 0222 coincides with the axis of the output shaft 0211 of the drive motor 021, but does not coincide with the axis of the first connecting shaft 0221.

[0110] The eccentric wheel body 0222 is connected to the output shaft 0211 of the drive motor 021, and the side of the eccentric wheel body 0222 facing away from the drive motor 021 is connected to one end of the first connecting shaft 0221. By aligning the eccentric wheel body 0222 with the axis of the output shaft 0211 of the drive motor 021, it is easier to transmit power from the drive motor 021 to the eccentric wheel 022, thereby better driving the water tank body 040 to rotate. By using the first connecting shaft 0221, which does not coincide with the axis of the output shaft 0211 of the drive motor 021, eccentric rotation of the water tank body 040 can be achieved, thereby improving the space utilization of the water tank 000.

[0111] Please refer to Figure 2In some possible implementations, the drive assembly 020 further includes a bracket 050 fixed to the first support surface M1. In a third direction perpendicular to the first support surface M1, the drive motor 021 is located between the bracket 050 and the first support surface M1, and the bracket 050 has a shaft hole K1.

[0112] At least a portion of the eccentric wheel body 0222 is rotatably connected to the bracket 050 within the shaft hole K1.

[0113] The shaft hole K1 on the bracket 050 can provide a certain degree of support for the eccentric wheel body 0222, and can also indirectly provide a certain degree of support for the transmission component 030 and the water tank body 040, thereby ensuring that the water tank body 040 can rotate smoothly.

[0114] For example, the eccentric wheel 022 further includes a docking shaft 0223. The docking shaft 0223 is located at one end of the eccentric wheel body 0222 away from the first connecting shaft 0221, that is, the docking shaft 0223 and the first connecting shaft 0221 are located at opposite ends of the eccentric wheel body 0222 axially. One end of the docking shaft 0223 is fixedly connected to the output shaft 0211 of the drive motor 021, and the other end is fixedly connected to the eccentric wheel body 0222.

[0115] The radial dimensions of the first connecting shaft 0221 and the docking shaft 0223 can both be smaller than the eccentric wheel body 0222, thus reducing weight and saving materials.

[0116] For example, a bearing can also be fixed inside the shaft hole K1, and at least a portion of the eccentric wheel body 0222 is located inside the bearing and rotatably connected to the bearing. In this way, the resistance when the eccentric wheel body 0222 rotates can be reduced, thereby reducing the power consumption of the drive motor 021.

[0117] The following examples illustrate two types of bracket 050. For easy distinction, one type of bracket 050 will be named the first bracket, and the other will be named the second bracket.

[0118] In one possible implementation, please refer to Figure 2 The first support 051 is a frame in the shape of a gate or similar to a gate.

[0119] The bottom of the first bracket 051 is directly fixedly connected to the first support surface M1, and the top of the first bracket 051 has a first shaft hole K11. At least a part of the eccentric wheel body 0222 is rotatably connected to the first bracket 051 in the first shaft hole K11.

[0120] The base 010 has a first mounting shell 011, which is located between the first support surface M1 and the first bracket 051, and is fixedly connected to the first support surface M1. The drive motor 021 is installed inside the first mounting shell 011, and one end of the output shaft 0211 is connected to the eccentric wheel 022 after passing through a hole on the first mounting shell 011.

[0121] In another possible implementation, please refer to Figure 5 , Figure 5 This is a schematic diagram of a partial water tank provided in an embodiment of this application. The base 010 has a second mounting shell 012, which is located between the first support surface M1 and the second bracket 052, and is fixedly connected to the first support surface M1. The drive motor 021 is installed inside the second mounting shell 012, and one end of the output shaft 0211 is connected to the eccentric wheel 022 through a hole on the second mounting shell 012.

[0122] The second bracket 052 is a block or plate structure. The second bracket 052 is fixed to the side of the second mounting shell 012 away from the first support surface M1. That is, the second bracket 052 is indirectly connected to the first support surface M1 through the second mounting shell 012.

[0123] The second bracket 052 has a second shaft hole K12, and at least a portion of the eccentric wheel body 0222 is rotatably connected to the second bracket 052 within the second shaft hole K12.

[0124] Please refer to Figure 2 In some possible implementations, the water tank 000 further includes a support assembly 060 located between the water tank body 040 and the first support surface M1. One side of the support assembly 060 is fixedly connected to the first support surface M1, and the other side is movably connected to the water tank body 040.

[0125] The water tank body 040 is supported by the support component 060, ensuring that the water tank body 040 can rotate smoothly under the action of the drive component 020 and the transmission component 030.

[0126] It is understandable that the so-called smooth rotation refers to the smooth rotation of the water tank body 040 in a direction parallel to the first support surface M1.

[0127] Please refer to Figure 2 In some possible implementations, the support assembly 060 includes at least two spaced-apart support columns 061. The outer wall of the water tank body 040 has at least two sleeve portions 041.

[0128] At least two support columns 061 and at least two sleeve parts 041 correspond one-to-one. Each sleeve part 041 is sleeved on the end of the corresponding support column 061 that is away from the first support surface M1 and is rotatably connected to the corresponding support column 061.

[0129] Among them, the end of the support column 061 facing away from the water tank body 040 is fixedly connected to the first support surface M1.

[0130] For example, the support component 060 includes two support columns 061 spaced apart in a first direction, and the corresponding water tank body 040 has a sleeve portion 041 on its outer side wall that is distributed opposite to each other in the first direction.

[0131] By rotating the sleeve 041 on the water tank body 040 and the end of the support column 061, the water tank body 040 can be supported without interfering with its rotation. Furthermore, the connection between the support column 061 and the sleeve 041 on the outer wall of the water tank body 040 reduces the height of the support column 061 in the third direction, thus enabling the water tank 000 to be miniaturized and compacted.

[0132] Figure 6 This is a schematic diagram of another water tank provided in the embodiments of this application. Please refer to it. Figure 6 In some possible implementations, each support column 061 includes: a first column 0611 and a second column 0612 distributed along the axial direction. One end of the first column 0611 is fixedly connected to a first support surface M1, and the other end of the first column 0611 is fixedly connected to one end of the second column 0612. The radial dimension of the first column 0611 is larger than the radial dimension of the second column 0612.

[0133] Each socket 041 has a socket hole K2, and the socket 041 is sleeved on the second column 0612 through the socket hole K2.

[0134] The radial dimension of the socket K2 is greater than the radial dimension of the second column 0612 and less than the radial dimension of the first column 0611.

[0135] Sufficient strength support can be provided by the first column 0611, which has a relatively larger radial dimension, and the second column 0612, which has a relatively smaller radial dimension, can be used to connect with the sleeve part 041.

[0136] In some possible implementations, the end face of the sleeve 041 facing the first support surface M1 contacts the end face of the first column 0611 facing away from the first support surface M1, that is, the end face of the sleeve 041 facing the first support surface M1 contacts the annular end face of the first column 0611 facing away from the first support surface M1. The inner wall of the sleeve 041 contacts the outer wall of the second column 0612.

[0137] By having the end face of the sleeve 041 facing the first support surface M1 contact the end of the first column 0611 opposite to the first support surface M1, sufficient support force can be provided to the water tank body 040. Furthermore, the inner wall of the sleeve 041 contacts the outer wall of the second column 0612, ensuring that during the rotation of the sleeve 041 relative to the second column 0612, the second column 0612 can always provide radial support and limit to the water tank body 040, thereby ensuring that the water tank body 040 can rotate relatively accurately along a preset trajectory.

[0138] For example, when the water tank body 040 rotates eccentrically, the radial dimension of the socket hole K2 is greater than the radial dimension of the second column 0612 and less than the radial dimension of the first column 0611. In this way, it can be ensured that the socket part 041 can rotate relative to the first column 0611, and the socket part 041 will not pass over the second column 0612 and the first column 0611 to be socketed, so that the socket part 041 can be stably socketed on the first column 0611.

[0139] The centerline of the socket K2 is eccentrically positioned relative to the centerline of the second column 0612, meaning that the centerline of the socket K2 and the centerline of the second column 0612 do not coincide. The centerline of the first column 0611 can coincide with the centerline of the second column 0612.

[0140] Please refer to Figure 6 In some possible implementations, the water tank body 040 includes: a water tank portion 042, and a buffer sleeve 043 sleeved on the outside of the water tank portion 042. The buffer sleeve 043 has a connecting portion 041 on its outer side facing away from the water tank portion 042, and the connecting portion 041 and the buffer sleeve 043 are integrally molded structures made of an elastic material. For example, the connecting portion 041 and the buffer sleeve 043 are integrally molded structures made of silicone.

[0141] When the water tank body 040 rotates, the water inside the water tank body 040 also rotates due to inertia. During the rotation, the water will move up and down relative to the first support surface M1, causing the water to impact the side of the water tank body 040 near the first support surface M1 in the direction perpendicular to the first support surface M1. This will indirectly transmit some vibration to the base 010 or other components on the base 010. This will generate some noise and may also cause the components inside the water tank 000 to become loose.

[0142] By using the sleeve 041 and buffer sleeve 043, which are integrally molded from elastic material, the vibration of the water in the water tank 000 that is transferred to the base 010 side due to rotation can be absorbed and buffered, thereby achieving the effects of vibration reduction and noise reduction.

[0143] Please refer to Figure 6 In some possible implementations, the outer wall of the water tank section 042 has at least two connecting portions 0421. The buffer sleeve 043 has at least two clearance openings 0431 corresponding one-to-one with the at least two connecting portions 0421, and each connecting portion 0421 extends through the corresponding clearance opening 0431 to extend outside the buffer sleeve 043.

[0144] Among them, at least two connecting parts 0421 correspond one-to-one with at least two second transmission rods 032, and each connecting part 0421 is fixedly connected to the end of the corresponding second transmission rod 032 that is away from the first transmission rod 031.

[0145] The connecting part 0421 is similar to a block or plate structure that protrudes outward from the outer side wall of the water tank part 042.

[0146] The connecting part 0421 facilitates the fixed connection between the second transmission rod 032 and the water tank part 042.

[0147] Please refer to Figure 6 In some possible implementations, the support assembly 060 further includes at least two elastic buffers 062. The at least two elastic buffers 062 are located between at least two support columns 061 and between the first support surface M1 and the water tank body 040.

[0148] In this configuration, one end of each elastic buffer 062 abuts against the first support surface M1, and the other end abuts against the side of the water tank body 040 facing the first support surface M1.

[0149] For example, the elastic buffer 062 is a coil spring. The number of elastic buffers 062 is configured to be two.

[0150] Understandably, the elastic buffer 062 is in a compressed state at this time, so that the elastic buffer 062 can provide support for the water tank body 040. Furthermore, when the water tank body 040 includes the water tank part 042 and the buffer sleeve 043, the elastic buffer 062 abuts against the side of the buffer sleeve 043 near the first support surface M1.

[0151] The elastic buffer 062 can provide support for the water tank body 040 and absorb and buffer the vibration of the water in the water tank body 040 that is transferred to the base 010 side due to rotation, thereby achieving the effects of vibration reduction and noise reduction.

[0152] Figure 7 This is a schematic diagram of another water tank provided in the embodiments of this application. Please refer to it. Figure 7 In some other possible implementations, the support component 060 includes a support platform 063 and at least two support legs 064.

[0153] At least two support legs 064 are located between the support platform 063 and the first support surface M1. One side of each support leg 064 is fixedly connected to the first support surface M1, and the other side is fixedly connected to one side of the support platform 063.

[0154] The water tank body 040 is located on the side of the support platform 063 away from the first support surface M1, and the water tank body 040 is slidably connected to the support platform 063.

[0155] The support platform 063 has a second support surface M2 on the side opposite to the base 010. The second support surface M2 provides support to the water tank body 040 and is slidably connected to the water tank body 040.

[0156] To reduce the resistance between the bottom of the water tank body 040 and the second support surface M2, so that the water tank body 040 can slide smoothly, a lubricating layer can be applied to the side of the water tank body 040 facing the support platform 063 and / or the second support surface M2. Alternatively, multiple balls can be provided on the side of the water tank body 040 facing the support platform 063, and the water tank body 040 can be rolledly connected to the second support surface M2 through the balls.

[0157] The support platform 063 provides sufficient support surface for the water tank body 040, thereby ensuring effective support for the water tank body 040. Furthermore, the support platform 063, in conjunction with at least two support legs 064, can also provide better support for the water tank body 040.

[0158] Please refer to Figure 7In some possible implementations, at least a portion of the first transmission rod 031 is located on the side of the bracket 050 in the drive assembly 020 opposite to the first support surface M1. The water tank 000 also includes a limiting assembly 070, which is located at least on the side of the first transmission rod 031 opposite to the bracket 050, and is movably connected to the bracket 050.

[0159] The limiting component 070 is used to limit the movement of the first transmission rod 031 in a third direction perpendicular to the first support surface M1.

[0160] It should be noted that bracket 050 here can be Figure 2 The first bracket 051 shown can also be Figure 5 The second bracket 052 is shown. Exemplary, the structural design between the limiting component 070 and the bracket 050 described below is mainly explained with reference to the second bracket 052.

[0161] By using the limiting component 070, which is movably connected to the bracket 050, the movement of the first transmission rod 031 in a third direction perpendicular to the first support surface M1 is restricted, which in turn restricts the position of the water tank body 040 in the third direction. This reduces the vibration and noise generated by the movement of the water tank body 040 in the third direction. In this way, the smooth rotation of the water tank body 040 can be better ensured.

[0162] Figure 8 This is a schematic diagram of the structure of a water tank according to another embodiment of this application. Please refer to it. Figure 8 In some possible implementations, the bracket 050 extends entirely along a first direction. The limiting assembly 070 includes: a pressure plate 071, a second connecting shaft 072, and two sliders 073.

[0163] Two sliders 073 are distributed on both sides of the bracket 050 in the second direction, and the sliders 073 are slidably connected to the bracket 050 in the first direction. The second direction intersects the first direction, and both the second direction and the first direction are parallel to the first support surface M1.

[0164] The two ends of the second connecting shaft 072 are fixedly connected to the two sliders 073 respectively.

[0165] The pressure plate 071 is fixed to the side of the first transmission rod 031 away from the bracket 050, and the pressure plate 071 is slidably connected to the second connecting shaft 072 in the second direction.

[0166] In the third direction, the second connecting shaft 072 is located on the side of the first transmission rod 031 away from the bracket 050.

[0167] For example, the first direction, the second direction, and the third direction are mutually perpendicular.

[0168] Since the first transmission rod 031 and the pressure plate 071 in the transmission assembly 030 are fixedly connected, and the pressure plate 071 is slidably connected to the second connecting shaft 072 in the second direction, and the slider 073 connected to the second connecting shaft 072 can be slidably connected to the bracket 050 in the first direction, the first transmission rod 031 can perform compound motion in the first and second directions under the drive of the drive assembly 020, thereby realizing eccentric rotation.

[0169] Furthermore, in the third direction, the first transmission rod 031 is located between the pressure plate 071 and the bracket 050. In this way, the positions of the first transmission rod 031, the second transmission rod 032, and the water tank body 040 in the third direction can be limited, thereby reducing the amount of vibration that the water tank body 040 brings to the internal components of the water tank 000.

[0170] Furthermore, this type of limit component 070 is easy to implement and has high reliability and feasibility.

[0171] For example, the number of limiting components 070 is configured to be two, and the two limiting components 070 are spaced apart in the first direction.

[0172] The transmission assembly 030 further includes an adapter 033, which is located on the side of the first transmission rod 031 facing away from the water tank body 040 in the second direction, and the adapter 033 is located at the middle position of the first transmission rod 031 in the first direction. The adapter 033 is movably connected to the first connecting shaft 0221.

[0173] The second bracket 052 has a protrusion 0521 corresponding to the adapter 033 on the side opposite to the water tank body 040 in the second direction, and the protrusion 0521 has a second shaft hole K12.

[0174] In one possible implementation, the two ends of the pressure plate 071 in the first direction are respectively located on both sides of the corresponding second connecting shaft 072, and the two ends are respectively fixedly connected to the first transmission rod 031. The middle part between the two ends of the pressure plate 071 has a through hole extending in the second direction. A portion of the second connecting shaft 072 is sleeved in the through hole, and the second connecting shaft 072 is slidably connected to the pressure plate 071 through the through hole.

[0175] The second connecting shaft 072 is slidably connected to the pressure plate 071 through a through hole, which facilitates more accurate restriction of the position of the first transmission rod 031 in the third direction. For example, the diameter of the through hole is the same as the shaft diameter of the second connecting shaft 072, or the diameter of the through hole is slightly larger than the shaft diameter of the connecting shaft.

[0176] In another possible implementation, the two ends of the pressure plate 071 in the first direction are respectively located on both sides of the corresponding second connecting shaft 072, and the two ends are respectively fixedly connected to the first transmission rod 031. The middle part between the two ends of the pressure plate 071 is an arc-shaped plate. The arc-shaped plate and the corresponding first transmission rod 031 are spaced apart and form a sleeve cavity. A part of the second connecting shaft 072 is located in the sleeve cavity and can slide relative to the sleeve cavity in the second direction.

[0177] Please refer to Figure 8 In some possible implementations, both the first transmission rod 031 and the bracket 050 extend along a first direction. In the first direction, the length of the first transmission rod 031 is greater than the length of the bracket 050, and the two ends of the first transmission rod 031 are located on the outside of the bracket 050.

[0178] In the second direction, the width of the first transmission rod 031 is less than the width of the bracket 050.

[0179] There are two second transmission rods 032, which are located at the two ends of the first transmission rod 031 in the first direction. The second direction intersects the first direction and is parallel to the first support surface M1.

[0180] For example, the side of the first transmission rod 031 facing the bracket 050 can contact the bracket 050.

[0181] Both the first transmission rod 031 and the bracket 050 extend along a first direction. In the first direction, the length of the first transmission rod 031 is greater than the length of the bracket 050, and the two ends of the first transmission rod 031 are located on the outside of the bracket 050. This not only allows the bracket 050 to support the first transmission rod 031, but also reduces the volume of the bracket 050, thereby reducing weight and cost, and also reduces the space occupied by the bracket 050, thus freeing up more space for flexible layout of the structure inside the water tank 000.

[0182] By having the width of the first transmission rod 031 smaller than the width of the bracket 050 in the second direction, the first transmission rod 031 has sufficient room to move relative to the bracket 050 in the second direction.

[0183] The two second transmission rods 032 are located at the two ends of the first transmission rod 031 in the first direction. This avoids interference between the bracket 050 and the second transmission rods 032, making the internal space design of the water tank 000 more rational.

[0184] Please refer to Figure 8For example, the base 010 has a second mounting shell 012, which is located between the first support surface M1 and the second bracket 052, and is fixedly connected to the first support surface M1. The drive motor 021 is installed inside the second mounting shell 012, and one end of the output shaft 0211 is connected to the eccentric wheel 022 after passing through a hole on the second mounting shell 012.

[0185] Please refer to Figure 5 The top of the second mounting shell 012 has multiple limiting blocks 0121. The shape of a portion of the second bracket 052 is consistent with the shape of the area enclosed by the multiple limiting blocks 0121, so that the portion of the second bracket 052 can be engaged within the multiple limiting blocks 0121.

[0186] Multiple limit blocks 0121 can limit the second bracket 052 to facilitate precise installation and positioning of the second bracket 052, thereby ensuring the assembly accuracy of the second bracket 052 and the structure on the second bracket 052.

[0187] Figure 9 This is a schematic diagram of the structure of a second support provided in an embodiment of this application. Please refer to it. Figures 8-9 The slider 073 has a groove C1 on the side facing the second bracket 052 in the second direction. The groove C1 is C-shaped or approximately C-shaped.

[0188] The second bracket 052 has guide plates 0522 on both sides of the second direction. The guide plates 0522 extend along the first direction, and each guide plate 0522 protrudes from the second bracket 052 on both sides of the third direction.

[0189] The slider 073 is slidably connected to the guide plate 0522 on the corresponding side.

[0190] Two relatively distributed guide plates 0522 can form a guide rail on the second bracket 052 to guide and limit the first transmission rod 031 on the second bracket 052. Furthermore, the guide plates 0522 can achieve both sliding connection with the slider 073 and high connection reliability.

[0191] In summary, because the middle position of the first transmission rod is connected to the drive assembly fixed to the first support surface of the base, and one end of each of the second transmission rods is fixedly connected to the first transmission rod, while the other end is fixedly connected to the outer wall of the water tank body, the drive assembly can drive the first transmission rod to rotate eccentrically, and through the second transmission rods, drive the water tank body to rotate eccentrically. Thus, when the water tank body rotates, the entire body rotates, and correspondingly, the water inside the water tank body also rotates along the entire inner wall of the water tank body, and the water rotation within the water tank body is relatively uniform. By the relatively uniform rotation of the water within the water tank body along the entire inner wall of the water tank body, the entire inner wall of the water tank body can be flushed and cleaned. This achieves automatic cleaning of the water tank and avoids the accumulation of dirt in the corners and edges of the water tank body, improving the cleaning effect and efficiency of the water tank.

[0192] Furthermore, the water tank in this application does not require a cleaning component to be placed inside the water tank body when it performs self-cleaning, which allows the water tank body to be smaller and achieves a miniaturized design.

[0193] Furthermore, since no cleaning components need to be placed inside the water tank, the internal structure of the water tank is simple, easy to design and implement, and can be adapted to more types or models of water tanks.

[0194] In addition, the drive component in the water tank is indirectly connected to the outer wall of the water tank body through the transmission component and performs eccentric drive, which can reduce the size of the water tank on both the perpendicular and parallel surfaces of the first support surface, which helps to achieve the miniaturization of the water tank and the rational spatial layout.

[0195] Another embodiment of this application provides a cleaning device, including a water tank 000 as described in any of the above embodiments.

[0196] Cleaning equipment includes, for example, floor scrubbers and sweepers.

[0197] Since the cleaning equipment includes the water tank 000 in the above embodiment, it can achieve automatic cleaning of the water tank 000, thereby improving the user experience.

[0198] In some possible implementations, the cleaning equipment also includes a cleaning host and a cleaning base station.

[0199] The cleaning host may include the water tank 000 in the above embodiments, and / or the cleaning base station may include the water tank 000 in the above embodiments.

[0200] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0201] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
