[0023] This application provides a cleaning device, see reference. Figures 1-2 , Figure 1 This is a schematic diagram of the structure of an embodiment of the cleaning equipment provided in this application; Figure 2This is a schematic diagram of a wastewater tank embodiment provided in this application. The cleaning device 10 includes a first housing 140, a pressure regulating member 110, a wastewater tank 120, and a clean water tank 130. The first housing 140 forms a receiving cavity (not shown in the figure), which is configured to receive the cleaning component 150 of the cleaning device 10. The clean water tank 130 is connected to the pressure regulating member 110 and the receiving cavity, and the pressure regulating member 110 is configured to increase the air pressure inside the clean water tank 130. The wastewater tank 120 is connected to the pressure regulating member 110 and the receiving cavity, and the pressure regulating member 110 is configured to decrease the air pressure inside the wastewater tank 120 to create a negative pressure. The pressure regulating member 110 is also configured to increase the gas in the wastewater tank 120 to the clean water tank 130.

[0024] Understandably, the pressure regulating component 110 of this embodiment draws the gas in the sewage tank 120 to the clean water tank 130, creating a negative pressure in the sewage tank 120 while increasing the gas pressure in the clean water tank 130. Under the negative pressure, the sewage in the containment chamber enters the sewage tank 120; under the pressurization, the output of liquid in the clean water tank 130 is accelerated. In other words, the cleaning device 10 of this application only requires one pressure regulating component 110 to achieve sewage suction and clean water replenishment. Unlike existing cleaning devices 10 that use water pumps and air pumps, the cleaning device 10 of this application does not require a water pump, thus reducing the cost of the cleaning device 10.

[0025] In one embodiment, the pressure regulator 110 may be a vacuum pump or an air pump, which is not limited here.

[0026] In one embodiment, the clean water tank 130 has a first cavity (not shown in the figure), which is provided with a water outlet (not shown in the figure) and an air inlet (not shown in the figure). The water outlet is connected to the receiving cavity, and the air inlet is connected to the air pump. The distance from the air inlet to the bottom of the first cavity is greater than the distance from the water outlet to the bottom of the first cavity.

[0027] Understandably, the air pump draws gas from the wastewater tank 120 and enters the first chamber through the air inlet. The clean water in the first chamber, under air pressure, is then output to the receiving chamber through the water outlet. In the height direction of the clean water tank 130, the distance from the air inlet to the bottom of the first chamber is greater than the distance from the water outlet to the bottom of the first chamber. In other words, the air inlet is located higher than the water outlet, allowing gas to quickly accumulate above the first chamber, creating air pressure on the clean water, thereby accelerating the water output from the clean water tank 130 and making the water output from the clean water tank 130 smoother.

[0028] In one embodiment, the air inlet is located at the top of the first cavity and the water outlet is located at the bottom of the first cavity. This arrangement increases the height difference between the air inlet and the water outlet, which can improve the water discharge speed and smoothness of the clean water tank 130. In addition, it can reduce the probability of liquid in the first cavity entering the air pump from the air outlet, thereby enhancing the reliability of the cleaning equipment 10.

[0029] In other embodiments, the air inlet is located on the side near the top of the first cavity, and the water outlet is located on the bottom or side near the bottom of the first cavity; or the air inlet is located on the top of the first cavity, and the water outlet is located on the side of the bottom, which is not limited here. In one embodiment, when the clean water tank 130 is a cubic clean water tank 130, the water inlet and the water outlet can be distributed on the same side of the clean water tank 130, or on opposite sides of the clean water tank 130, or on adjacent sides of the clean water tank 130, which is not limited here.

[0030] In one embodiment, the wastewater tank 120 is equipped with a gas-liquid separator 125. The gas-liquid separator 125 has a gas flow channel (not shown in the figure) and divides the internal space of the wastewater tank 120 into a second cavity 1251 and a third cavity 1221 that are interconnected by the gas flow channel. The wastewater tank 120 is also equipped with an inlet communicating with the second cavity 1251 and an outlet communicating with the third cavity 1221. The inlet is connected to the receiving cavity, and the outlet is connected to an air pump. Understandably, the air pump extracts the gas from the wastewater tank 120 through the outlet to create a negative pressure inside the wastewater tank 120. Under the action of the negative pressure, the wastewater in the receiving cavity enters the second cavity 1251 through the inlet. The gas-liquid mixture can achieve most of the gas and liquid separation under the action of the gas-liquid separator 125. The finally separated gas is stored in the third cavity 1221 or the upper space of the second cavity 1251, waiting to be pumped away by the air pump. The gas-liquid mixture is stored in the third cavity.

[0031] In this embodiment, the wastewater tank 120 is equipped with a gas-liquid separator 125, which enables most of the gas-liquid mixture drawn into the wastewater tank to be separated. The air pump extracts the gas from the second chamber 1251 and the third chamber 1221 through the air outlet, creating a negative pressure inside the wastewater tank 120. This negative pressure is then used to draw the wastewater from the receiving chamber into the second chamber 1251. Furthermore, the gas-liquid separation prevents wastewater from entering the clean water tank 130 through the air pump from the air outlet, thus preventing the clean water tank 130 from being contaminated.

[0032] In one embodiment, the wastewater tank 120 includes a second housing 121, a third housing 122, and a first cover 123. The first housing 140 forms a receiving groove. The third housing 122 is disposed in the receiving groove and has an opening 1222 and a third cavity 1221 communicating with the opening 1222. A gas-liquid separator 125 forms a second cavity 1251 and is disposed within the third cavity 1221. The first cover 123 covers the opening 1222. The wastewater tank 120 of this embodiment has a simple structure and is easy to implement.

[0033] In one embodiment, the first cover 123 has a drain outlet 1231 located above the corresponding opening 1222 of the second cavity 1251, and the inlet is located on the side wall of the second cavity 1251. The sewage tank 120 also includes a second cover 124, which covers the drain outlet 1231 and is detachably connected to the first cover 123. In this embodiment, by operating the second cover 124, sewage in the second cavity 1251 can be discharged from the sewage tank 120 through the drain outlet 1231 without having to open the entire first cover 123, making the operation more convenient. In addition, the second cover 124 can ensure the airtightness of the sewage tank 120, ensuring that negative pressure can be formed inside the sewage tank 120, thereby enhancing the reliability of the sewage and cleaning water circulation of the cleaning equipment 10.

[0034] In one embodiment, the gas-liquid separator 125 is detachably disposed at the drain outlet 1231 and extends through the drain outlet 1231 into the third cavity 1221.

[0035] In one embodiment, the cleaning device 10 further includes a filter element (not shown in the figure), which is disposed at the drain outlet 1231 and extends through the drain outlet 1231 to the second cavity 1251 to filter sewage.

[0036] In one embodiment, the cleaning device 10 further includes a seal (not shown in the figure), which is disposed between the first cover and the second cover to enhance the airtightness of the internal space of the sewage tank 120.

[0037] In one embodiment, the wastewater tank 120, air pump, clean water tank 130, and first housing 140 are arranged along a first direction, with the air pump and clean water tank 130 located between the wastewater tank 120 and the first housing 140, and the air pump located between the clean water tank 130 and the wastewater tank 120. Here, the first direction refers to the direction from the rear to the front of the cleaning device 10, or the rear-forward direction of the cleaning device 10; both the first direction and the rear-forward direction are unidirectional. That is, the wastewater tank 120, air pump, clean water tank 130, and first housing 140 are arranged sequentially along the rear-forward direction. This arrangement of the embodiment results in shorter wastewater paths between the wastewater tank 120 and the first housing 140, shorter airflow paths between the air pump and the clean water tank 130, and shorter clean water paths between the clean water tank 130 and the first housing 140, leading to a more compact structure and reducing the size of the cleaning device 10 in the first direction.

[0038] This application also provides a cleaning system (not shown in the figure), which includes a cleaning device 10 and a base station (not labeled in the figure). The cleaning device 10 and the base station are detachably connected. The cleaning device 10 is configured to clean the surface to be cleaned. The base station is configured to at least charge the cleaning device 10. Specifically, the cleaning device 10 can be any of the cleaning devices 10 described in the above embodiments, and is not limited thereto. The base station can be a push-in base station, or it can be a plug-in or removable base station, and is not limited thereto.

[0039] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
