Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, in particular to a wastewater tank, a cleaning equipment, and a cleaning system.Background

[0002] With the development of social economy and the improvement of people's living standards, cleaning equipment such as floor washers and vacuum cleaners are increasingly applied in people's daily lives due to their advantages of high cleaning efficiency, time-saving, and labor-saving.

[0003] Most models of floor washers on the market need to create a negative pressure state in the inner cavity of the wastewater tank through the suction channel in the cover of the wastewater tank, so as to suck the wastewater on the ground into the wastewater tank through the wastewater inlet channel.

[0004] However, during operations such as moving or lying flat the cleaning equipment, wastewater may churn and surge, entering the suction channel. This can potentially cause water to enter the motor and damage it, as well as wet and disable the filtration device.Summary of the Invention

[0005] In view the above-mentioned problems, the present application provides a wastewater tank, a cleaning equipment, and a cleaning system, which allow to reduce the risk of wastewater entering the suction channel, resulting in the wetting and failure of the filter assembly and the damage of the suction device caused by water-ingress.

[0006] The present application provides a wastewater tank for cleaning equipment, which comprises: a tank body having an accommodating cavity with one end open and a wastewater inlet channel extending in a height direction of the tank body, wherein the wastewater inlet channel has a communication port communicating with the accommodating cavity; a tank cover assembly arranged at an opening of the tank body and defining a suction channel communicating with the accommodating cavity; and a water-blocking assembly comprising a water-blocking frame and a water-blocking block, wherein the water-blocking frame at least partially surrounds a periphery of the wastewater inlet channel, the suction channel and the wastewater inlet channel are separated by the water-blocking frame, the water-blocking block is arranged on a side of the water-blocking frame facing away from the wastewater inlet channel, and the water-blocking block is configured to prevent the wastewater in the accommodating cavity from surging towards the suction channel when the cleaning equipment is moving or lying flat.

[0007] In the wastewater tank of the present application, the water-blocking frame can block most of the water vapor from flowing directly to the suction channel, and the water-blocking block can inhibit the wastewater from surging towards the suction channel due to the surge phenomenon. Through the cooperation of the water-blocking frame and the water-blocking block, the probability of the filter assembly getting wet and failing and the suction device being damaged by water ingress can be reduced, thereby improving the reliability of the cleaning equipment and being beneficial to improving the user experience.

[0008] In some embodiments, the water-blocking block has a set height lower than the height of the communication port, and the water-blocking block has a height not lower than a maximum allowable water level of the wastewater tank.

[0009] In this way, when a surge occurs, it can ensure that the water-blocking block can prevent the water on the lower side of the water-blocking block from churning to the upper side, ensuring the water-blocking effect.

[0010] In some embodiments, the set height of the water-blocking block is 1 / 2 ~ 4 / 5 of a height of the wastewater inlet channel.

[0011] In this way, on the one hand, the effectiveness of the water-blocking function of the water-blocking block is ensured, and on the other hand, the wastewater tank is ensured to have a sufficient wastewater capacity.

[0012] In some embodiments, the suction channel and the water-blocking block are located on a same side of the water-blocking frame.

[0013] In this way, the water-blocking block can better block the wastewater from directly surging towards the suction channel.

[0014] In some embodiments, the water-blocking block has a shape adapted to that of the accommodating cavity. The water-blocking block divides the accommodating cavity into a first sub-chamber and a second sub-chamber. The first sub-chamber is located on a side of the water-blocking block facing the tank cover assembly, and at least part of the second sub-chamber is located on a side of the water-blocking block facing away from the tank cover assembly.

[0015] In this way, after the wastewater enters the accommodating cavity, it can be in the second sub-chamber. On the one hand, the provision of the first sub-chamber facilitates the air circulation in the wastewater tank. On the other hand, the first sub-chamber can serve as a buffer space between the suction channel and the water-blocking block. Even if some wastewater reaches the upper side of the water-blocking block due to a surge, it can be buffered by the first sub-chamber to avoid entering the suction channel.

[0016] In some embodiments, the water-blocking block is provided with a through-hole communicating the first sub-chamber and the second sub-chamber; and / or, a gap communicating the first sub-chamber and the second sub-chamber is defined between the water-blocking block and an inner wall of the tank body.

[0017] In this way, when the cleaning equipment is working, the air in the second sub-chamber can enter the first sub-chamber through the through-hole and finally be sucked into the suction channel, facilitating the entry of wastewater into the second sub-chamber from the wastewater inlet channel. In addition, when a surge occurs, the provision of the through-hole can reduce the impact of the wastewater on the water-blocking block. Alternatively, the air in the second sub-chamber can enter the first sub-chamber through the gap and finally be sucked into the suction channel, facilitating the entry of wastewater into the second sub-chamber from the wastewater inlet channel.

[0018] In some embodiments, the water-blocking frame has a first end connected to the tank cover assembly and a second end extending to a side of the communication port away from the tank cover assembly in the height direction, and the water-blocking block is arranged adjacent to the second end.

[0019] In this way, it can ensure that there is a sufficient distance between the water-blocking block and the suction channel. Thus, when the wastewater surges, even if a small amount of wastewater churns to the upper side of the water-blocking block, it can be maximally prevented from entering the suction channel and wetting the filter assembly.

[0020] In some embodiments, the water-blocking block is detachably connected to the water-blocking frame; or, the water-blocking block is integrally formed with the water-blocking frame.

[0021] In this way, in the event that the water-blocking block is detachably connected to the water-blocking frame, after the wastewater tank has been used for a period of time, it is convenient for the user to separate the water-blocking frame and the water-blocking block for cleaning respectively, reducing the growth of bacteria on the water-blocking assembly. In the event that the water-blocking block is integrally formed with the water-blocking frame, the stability of installation of the water-blocking block on the water-blocking frame is higher. When the wastewater surges, the water-blocking block can withstand a greater impact to better buffer and inhibit the surge.

[0022] In some embodiments, the water-blocking frame and a side wall of the tank body jointly define an enclosed space. A projection of the wastewater inlet channel on a reference plane is located within a projection of the enclosed space on the reference plane. The reference plane is perpendicular to the height direction of the wastewater tank.

[0023] In this way, the water-blocking frame can better block the water vapor from being sucked into the suction channel, thereby reducing the risk of the filter assembly getting wet and the suction device being damaged by water ingress. Moreover, there is a gap between the outer wall of the wastewater inlet channel and the inner wall of the enclosed space, facilitating the entry of wastewater from the wastewater inlet channel into the accommodating cavity.

[0024] In some embodiments, the water-blocking frame is provided with an air-passing port. In the height direction of the wastewater tank, the air-passing port is located between the communication port and the water-blocking block.

[0025] By providing the air-passing port, when the suction device sucks air, it is easier to form a negative pressure in the wastewater inlet channel to ensure the suction force for the wastewater.

[0026] In some embodiments, the wastewater tank further comprises a water-level detection device. The water-level detection device is arranged on at least one of the water-blocking frame and the water-blocking block.

[0027] In this way, the water-blocking frame and the water-blocking block can be used to provide an installation platform for the water-level detection device, eliminating the need to provide a separate installation structure for the water-level detection device.

[0028] In some embodiments, the wastewater tank further comprises an alarm device. The alarm device is configured to issue an alarm when the water-level detection device detects that the water level in the wastewater tank reaches a preset water level.

[0029] In this way, the alarm device can remind the user to empty the wastewater, further enhancing the user experience.

[0030] In some embodiments, the alarm device and the water-level detection device are of an integrated structure.

[0031] In this way, the integration degree is higher, less space is occupied, and the effective volume of the wastewater tank can be increased.

[0032] The second aspect of the present application provides a cleaning equipment, which comprises: an equipment body; a cleaning assembly for cleaning a surface to be cleaned; and the wastewater tank according to the first aspect of the present application. The wastewater tank is arranged on the equipment body and configured to store wastewater sucked in by the cleaning assembly.

[0033] The cleaning equipment of the present application, by providing the above-mentioned wastewater tank, can reduce the probability of the filter assembly getting wet and failing and the suction device being damaged by water ingress, thereby improving the reliability of the cleaning equipment and being beneficial to improving the user experience.

[0034] The third aspect of the present application provides a cleaning system, which comprises: the cleaning equipment according to the second aspect of the present application; and a cleaning base station. The cleaning base station is at least configured to clean the cleaning equipment.

[0035] In the cleaning system of the present application, by providing the above-mentioned cleaning equipment, the reliability of the system can be improved, which is beneficial to enhancing the user experience.Description of the Drawings

Detailed Description of Embodiments

[0038] To make the above-mentioned objectives, features, and advantages of the embodiments of the present application more clearly understandable, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0039] With the development of social economy and the improvement of people's living standards, cleaning equipment such as floor washers and vacuum cleaners are increasingly applied in people's daily lives due to their advantages of high cleaning efficiency, time-saving, and labor-saving. Most models of floor washers on the market need to create a negative pressure state in the inner cavity of the wastewater tank through the suction channel in the cover of the wastewater tank, so as to suck the wastewater on the ground into the wastewater tank through the wastewater inlet channel. However, when the cleaning equipment is operating, since operations such as moving or lying flat the cleaning equipment may cause wastewater to churn and surge, and enter the suction channel. This can potentially cause water to enter the motor and damage it, as well as wet and disable the filtration device.

[0040] In view of this, the present application provides a wastewater tank, a cleaning equipment, and a cleaning system. The water-blocking frame can block most of the water vapor from flowing directly to the suction channel, and the water-blocking block can, to a certain extent, inhibit the wastewater in the wastewater tank from surging towards the suction channel due to the surge phenomenon. Through the cooperation of the water-blocking frame and the water-blocking block, the probability of the filter assembly getting wet and failing and the suction device being damaged by water ingress can be reduced, thereby improving the reliability of the cleaning equipment and being beneficial to improving the user experience.

[0041] The wastewater tank 100 according to an embodiment of the first aspect of the present application is described below in conjunction with Figs. 1 - 3.

[0042] The wastewater tank 100 of this embodiment can be used for cleaning equipment. The cleaning equipment can be a floor washer, a cleaning robot, a vacuum cleaner with a mopping function, etc. The cleaning equipment can be household or industrial cleaning equipment, and the present application does not limit this.

[0043] The cleaning equipment can comprise an equipment body and a cleaning assembly. The equipment body can be used to accommodate the wastewater tank 100 which is detachably arranged on the equipment body. The equipment body can also provide an installation platform and support for other components of the cleaning equipment. The cleaning assembly can be arranged at a bottom end of the equipment body. The cleaning assembly can travel along the surface to be cleaned and clean it. For example, the cleaning assembly can comprise a roller brush and a side brush. The side brush can gather the dirt around the cleaning assembly to the center of the cleaning assembly, and the roller brush can suck in the dirt, wastewater, etc.

[0044] Referring to Fig. 1, the wastewater tank 100 can comprise: a tank body 1, a tank cover assembly 2, and a water-blocking assembly 3.

[0045] Among them, the tank body 1 can define an accommodating cavity 11 with one end open. The opening forms a wastewater discharge port. For example, the top of the tank body 1 is open to form a wastewater discharge port. The accommodating cavity 11 can be used to store the wastewater and dirt sucked in during the operation of the cleaning equipment. The tank body 1 can have a shape of circular cylinder, square cylinder, or be irregular in shape. The shape of the tank body 1 is adapted to the shape of the space in the equipment body for accommodating the tank body 1.

[0046] The tank body 1 also has a wastewater inlet channel 12 which extends in the height direction of the tank body 1. The wastewater inlet channel 12 has a communication port 121 communicating with the accommodating cavity 11. For example, a channel partition is arranged in the accommodating cavity 11 and is in the shape of a cylinder with both ends open. The channel partition extends in the height direction of the tank body 1 and defines the wastewater inlet channel 12 with the communication port 121 located at the top end of the channel partition.

[0047] The tank cover assembly 2 is arranged at the opening of the tank body 1 to seal the wastewater discharge port. When the wastewater in the tank body 1 reaches the set capacity or in other cases where the wastewater needs to be poured out, the tank cover assembly 2 can be removed from the tank body 1 such that the wastewater can be poured out from the wastewater discharge port. The tank cover assembly 2 defines a suction channel 211 which communicates with the accommodating cavity 11. For example, the tank cover assembly 2 can comprise a tank cover 21, and the suction channel 211 is arranged in the tank cover 21.

[0048] In this way, when the cleaning equipment is working, a suction device on the equipment body, such as a suction motor, can perform a suction on the accommodating cavity 11 through the suction channel 211, making the accommodating cavity 11 in a negative pressure state, so as to facilitate sucking the wastewater and dirt on the surface to be cleaned into the wastewater tank 100 from the cleaning assembly through the wastewater inlet channel 12. The surface to be cleaned can be a ground, a desktop, etc.

[0049] It can be understood that the wastewater tank 100 can further comprise a filter assembly 5 arranged in the suction channel 211. The filter assembly 5 can prevent the wastewater droplets and dirt in the wastewater tank 100 from reaching the suction device through the suction channel 211, resulting in water-ingress damage to the suction device. Moreover, the filter assembly 5 is detachably matched with the tank cover assembly 2, so that after the filter assembly 5 has been working for a period of time, it can be removed for cleaning or replacement. Optionally, the filter assembly 5 can comprise an installation frame 51 and a filter 52. Specifically, the installation frame 51 can be detachably matched with the tank cover assembly 2 and provide good support for the filter 52. The filter 52 is arranged in the installation frame 51 and is located in the suction channel 211. The filter 52 can be a HEPA filter, a filter screen, etc.

[0050] The water-blocking assembly 3 can comprise a water-blocking frame 31 and a water-blocking block 32. The water-blocking frame 31 can be connected to the tank body 1, or connected to the tank cover assembly 2, or simultaneously connected to the tank body 1 and the tank cover assembly 2. The water-blocking frame 31 at least partially surrounds the periphery of the wastewater inlet channel 12. The suction channel 211 and the wastewater inlet channel 12 are separated by the water-blocking frame 31. In this way, when the wastewater enters the accommodating cavity 11 through the wastewater inlet channel 12, the water-blocking frame 31 can block part of the water vapor from flowing to the suction channel 211, reducing the probability of the filter assembly 5 getting wet and the suction device being damaged by water ingress.

[0051] The water-blocking block 32 is arranged on the side of the water-blocking frame 31 facing away from the wastewater inlet channel 12. The water-blocking block 32 is configured to prevent the wastewater in the accommodating cavity 11 from surging towards the suction channel 211 when the cleaning equipment is moving or lying flat. In other words, the water-blocking block 32 can inhibit the wastewater in the wastewater tank 100 from surging towards the suction channel 211 due to the surge phenomenon. In this way, it can prevent a large amount of wastewater from reaching the suction device through the suction channel 211, resulting in the wetting and failure of the filter assembly 5 and the water-ingress damage of the suction device.

[0052] In the wastewater tank 100 according to the embodiment of the present application, the water-blocking frame 31 can block most of the water vapor from flowing directly to the suction channel 211, and the water-blocking block 32 can, to a certain extent, inhibit the wastewater in the wastewater tank 100 from surging towards the suction channel 211 due to the surge phenomenon. Through the cooperation of the water-blocking frame 31 and the water-blocking block 32, the probability of the filter assembly 5 getting wet and failing and the suction device being damaged by water ingress can be reduced, thereby improving the reliability of the cleaning equipment and being beneficial to improving the user experience.

[0053] Referring to Fig. 1, the set height of the water-blocking block 32 is lower than the height of the communication port 121, and the height of the water-blocking block 32 is not lower than the maximum allowable water level of the wastewater tank 100. It can be understood that the highest liquid level in the wastewater tank 100, that is, the maximum allowable water level, will not exceed the height of the communication port 121. Therefore, the height of the water-blocking block 32 in this embodiment is between that of the communication port 121 and the maximum allowable water level. When a surge occurs, it can ensure that the water-blocking block 32 can prevent the water below it from churning to be above it, ensuring the water-blocking effect.

[0054] In some embodiments, the set height of the water-blocking block 32 is 1 / 2 ~ 4 / 5 of the height of the wastewater inlet channel 12. For example, the set height of the water-blocking block 32 is 1 / 2, 2 / 3, 3 / 4, or 4 / 5 of the height of the wastewater inlet channel 12. Of course, the present application does not limit this, and the height of the water-blocking block 32 can be reasonably selected within the above-mentioned range. In this way, on the one hand, the effectiveness of the water-blocking function of the water-blocking block 32 is ensured, and on the other hand, the wastewater tank 100 is ensured to have a sufficient wastewater capacity.

[0055] In some embodiments, referring to Fig. 1, the suction channel 211 and the water-blocking block 32 are located on the same side of the water-blocking frame 31. In this way, the water-blocking block 32 can better block the wastewater from directly surging towards the suction channel 211.

[0056] In some embodiments, referring to Fig. 1, the shape of the water-blocking block 32 is adapted to the shape of the accommodating cavity 11. The water-blocking block 32 divides the accommodating cavity 11 into a first sub-chamber 111 and a second sub-chamber 112. The first sub-chamber 111 is located on the side of the water-blocking block 32 facing the tank cover assembly 2, and at least part of the second sub-chamber 112 is located on the side of the water-blocking block 32 facing away from the tank cover assembly 2.

[0057] In this way, after the wastewater enters the accommodating cavity 11, it can be in the second sub-chamber 112. On the one hand, the provision of the first sub-chamber 111 facilitates the air circulation in the wastewater tank 100, and on the other hand, the first sub-chamber 111 can serve as a buffer space between the suction channel 211 and the water-blocking block 32. Even if some wastewater reaches the upper side of the water-blocking block 32 due to a surge, it can be buffered by the first sub-chamber 111 to avoid entering the suction channel 211.

[0058] In some possible embodiments, the water-blocking block 32 can be provided with a through-hole (not shown in the figures). The through-hole penetrates the water-blocking block 32 in its thickness direction and can communicate the first sub-chamber 111 and the second sub-chamber 112. The through-hole can be a round hole, a square hole, or have any other shape. In the thickness direction of the water-blocking block 32, the cross-sectional area of the through-hole can be the same everywhere, or can gradually increase or gradually decrease. In this way, when the cleaning equipment is working, the air in the second sub-chamber 112 can enter the first sub-chamber 111 through the through-hole and finally be sucked into the suction channel 211, facilitating the entry of wastewater into the second sub-chamber 112 from the wastewater inlet channel 12. In addition, when a surge occurs, the provision of the through-hole can reduce the impact of the wastewater on the water-blocking block 32.

[0059] In some embodiments, referring to Fig. 1, there is a gap between the water-blocking block 32 and the inner wall of the tank body 1, which communicates the first sub-chamber 111 and the second sub-chamber 112. In this way, when the cleaning equipment is working, the air in the second sub-chamber 112 can enter the first sub-chamber 111 through the gap and finally be sucked into the suction channel 211, facilitating the entry of wastewater into the second sub-chamber 112 from the wastewater inlet channel 12.

[0060] Optionally, only a through-hole can be provided in the water-blocking block 32; or only a gap can be defined between the water-blocking block 32 and the inner wall of the tank body 1; or both a through-hole and a gap can be provided to ensure the efficiency of air flow between the first sub-chamber 111 and the second sub-chamber 112.

[0061] In some embodiments, as shown in Figs. 1 and 3, the first end of the water-blocking frame 31 is connected to the tank cover assembly 2, and the second end of the water-blocking frame 31 extends to the side of the communication port 121 away from the tank cover assembly 2 in the height direction, for example, the lower side of the communication port 121. The water-blocking block 32 is arranged adjacent to the second end. In this way, it can ensure that there is a sufficient distance between the water-blocking block 32 and the suction channel 211. Thus, when the wastewater surges, even if a small amount of wastewater churns to the upper side of the water-blocking block 32, it can be maximally prevented from entering the suction channel 211 and wetting the filter assembly 5.

[0062] In some embodiments, referring to Fig. 2, the water-blocking block 32 is detachably connected to the water-blocking frame 31. For example, the water-blocking frame 31 can be provided with a fixing part, and the water-blocking block 32 can be provided with a connecting part. The fixing part can be a structure such as a snap-fit groove or an insertion hole, and the connecting part can be a protruding structure or a plug post that is adapted to the fixing part, so that the water-blocking block 32 can be detachably installed on the water-blocking frame 31. In this way, the assembly between the water-blocking block 32 and the water-blocking frame 31 is simple and easy to carry out. Moreover, it is convenient for the user to separate the water-blocking frame 31 and the water-blocking block 32 for cleaning respectively after the wastewater tank 100 has been used for a period of time, reducing the growth of bacteria on the water-blocking assembly 3.

[0063] Of course, in some alternative embodiments, the water-blocking block 32 and the water-blocking frame 31 can be integrally formed. In this way, the stability of installation of the water-blocking block 32 on the water-blocking frame 31 is higher. When the wastewater surges, the water-blocking block 32 can withstand a greater impact to better buffer and inhibit the surge.

[0064] In some embodiments, referring to Fig. 1, the water-blocking frame 31 and the side wall of the tank body 1 jointly define an enclosed space. The projection of the wastewater inlet channel 12 on a reference plane is located within the projection of the enclosed space on the reference plane. The reference plane is perpendicular to the height direction of the wastewater tank 100. In this way, the water-blocking frame 31 can better block the water vapor from being sucked into the suction channel 211, thereby reducing the risk of the filter assembly 5 getting wet and the suction device being damaged by water ingress. Moreover, there is a gap between the outer wall of the wastewater inlet channel 12 and the inner wall of the enclosed space, facilitating the entry of wastewater from the wastewater inlet channel 12 into the accommodating cavity 11.

[0065] In some embodiments, referring to Fig. 2, the water-blocking frame 31 is provided with an air-passing port 311. In the height direction of the wastewater tank 100, the air-passing port 311 is located between the communication port 121 and the water-blocking block 32. By providing the air-passing port 311, when the suction device sucks air through the suction channel 211, it is easier to form a negative pressure in the wastewater inlet channel 12 to ensure the suction force for the wastewater on the surface to be cleaned.

[0066] Optionally, only one air-passing port 311 with a big area can be provided; or multiple air-passing ports 311 with a smaller flow-through area can be provided to ensure the air circulation on both sides of the enclosed space.

[0067] In some embodiments, as shown in Figs. 2 and 3, the wastewater tank 100 can further comprise a water-level detection device 4 arranged on either the water-blocking frame 31 or the water-blocking block 32. For example, the water-level detection device 4 can be only arranged on the water-blocking frame 31, or only arranged on the water-blocking block 32, or part of the water-level detection device 4 can be arranged on the water-blocking frame 31 and the other part on the water-blocking block 32. In this way, the water-blocking frame 31 and the water-blocking block 32 can be used to provide an installation platform for the water-level detection device 4, eliminating the need to configure a separate installation structure for the water-level detection device 4.

[0068] Optionally, as shown in Fig. 2, the water-level detection device 4 comprises a first detection terminal 41 and a second detection terminal 42. When the wastewater in the wastewater tank 100 reaches the maximum allowable water level, the first detection terminal 41 and the second detection terminal 42 are electrically connected through the wastewater, and it can be determined that the wastewater in the wastewater tank 100 is full. Then, it can notify the user to empty the wastewater or make the cleaning equipment return to the cleaning base station for self-cleaning.

[0069] Furthermore, as shown in Figs. 2 and 3, the water-level detection device 4 is arranged on the water-blocking frame 31 and is located on the side of the water-blocking block 32 away from the tank cover assembly 2. Since the height where the water-level detection device 4 is located corresponds to the maximum allowable water level of the wastewater tank 100, the water-blocking block 32 is higher than the maximum allowable water level. In this way, there is a certain height difference between the water-blocking block 32 and the water level of the wastewater. The space corresponding to this height difference can be used to buffer the surging wastewater and reduce the potential energy of the wastewater on the water-blocking block 32, so that the water-blocking block 32 can better block the surge.

[0070] In some embodiments, the wastewater tank 100 can further comprise an alarm device. The alarm device can be a sound and light alarm device or a video alarm device. For example, an alarm image can be displayed on the display interface of the host of the cleaning equipment. The alarm device is configured to issue an alarm when the water-level detection device 4 detects that the water level in the wastewater tank 100 reaches the preset water level to remind the user to empty the wastewater. In this way, the user experience can be further enhanced.

[0071] In some embodiments, the alarm device and the water-level detection device 4 are of an integrated structure. In this way, the integration degree is higher, less space is occupied, and the effective volume of the wastewater tank 100 can be increased.

[0072] The following describes the cleaning equipment according to an embodiment of the second aspect of the present application.

[0073] The cleaning equipment of this embodiment can be a floor washer, a cleaning robot, a vacuum cleaner with a mopping function, etc. The cleaning equipment can be household or industrial cleaning equipment, and the present application does not limit this.

[0075] The cleaning assembly can be arranged at the bottom end of the equipment body. The cleaning assembly can travel along the surface to be cleaned to clean it. For example, the cleaning assembly can comprise a roller brush and a side brush. The side brush can gather the dirt around the cleaning assembly to the center of the cleaning assembly, and the roller brush can clean and brush the surface to be cleaned and suck in the dirt, wastewater, etc. The wastewater tank 100 is configured to store the wastewater sucked in by the cleaning assembly.

[0076] The cleaning equipment of this embodiment, by providing the wastewater tank 100 in the above-mentioned embodiments, can reduce the probability of the filter assembly 5 getting wet and failing and the suction device being damaged by water ingress, thereby improving the reliability of the cleaning equipment and being beneficial to improving the user experience.
