Technical Field

[0001] This application relates to the technical field of cleaning equipment, specifically to a cleaning system. Background Technology

[0002] As people pay more and more attention to indoor air quality, cleaning equipment such as robot vacuum cleaners and floor scrubbers have gradually become one of the essential household appliances.

[0003] In related technologies, by placing the cleaning equipment on the base station and opening the sewage outlet at the bottom of the sewage tank, the sewage in the sewage tank of the cleaning equipment is discharged through the sewage outlet of the base station through the liquid drop. However, this sewage discharge method can result in dirt residue remaining on the inner wall of the sewage tank, which makes it very easy for bacteria to grow inside the sewage tank and even produce a musty or foul smell. Utility Model Content

[0004] This application provides a cleaning system to solve the technical problem that the inner wall of the sewage tank of existing cleaning equipment is covered with dirt, which makes it easy for bacteria to grow inside the sewage tank and even produce a musty or foul odor.

The cleaning equipment is equipped with a gas power mechanism for suctioning air from the sewage chamber. When the base station cooperates with the cleaning equipment to clean the cleaning equipment, the suction port is located in the water storage tank; when the gas power mechanism draws air from the sewage chamber, the clean water in the water storage tank flows into the sewage chamber through the suction port and the suction channel, and the discharge port and the sewage outlet are alternately connected or disconnected, so that the clean water in the sewage chamber is in a turbulent state.

The second switch door is installed in the water-leaking chamber to alternately open or close the drain hole. The opening device is fixed to the water-leaking chamber or the housing. The first switch door is movably installed in the main body. When the cleaning equipment cooperates with the base station, the opening device drives the first switch door to open the drain outlet, so that the water-leaking cavity communicates with the drain outlet.

[0009] In some embodiments, the drain hole is disposed on the side wall of the leak chamber, and the second switch door is rotatably mounted on the side of the leak chamber opposite to the leak cavity.

When the cleaning equipment cooperates with the base station, the switch drives the first switch door to alternately open or close the drain outlet.

[0012] In some embodiments, the switch is slidably mounted on the housing in the vertical direction, and the drive assembly is used to drive the switch to reciprocate in the vertical direction; or the switch is rotatably mounted on the housing, and the switch is cam-shaped.

[0013] In some embodiments, the gas power mechanism is also used to inflate the sewage chamber to dry the cleaned suction channel and the sewage chamber.

[0014] In some embodiments, the cleaning device further includes a heating element mounted on the gas power mechanism or the main body and used to heat the air to be filled into the sewage chamber.

[0021] This application provides a cleaning system 10, such as Figures 1 to 5As shown, the cleaning system 10 includes a base station 100 and a cleaning device 200. The base station 100 includes a housing 110, which has a water storage tank 111 and a drain outlet 112. The water storage tank 111 is used to store cleaning water. The cleaning device 200 has a suction port 211, a suction channel 212, a sewage chamber 213, and a sewage outlet 214 connected in sequence. The cleaning device 200 is equipped with a pneumatic power mechanism 220, which is used to draw air from the sewage chamber 213. When the base station 100 cooperates with the cleaning equipment 200 to clean the cleaning equipment 200, the suction port 211 is located in the water storage tank 111; when the gas power mechanism 220 draws air from the sewage chamber 213, the clean water in the water storage tank 111 flows into the sewage chamber 213 through the suction port 211 and the suction channel 212, and the discharge port 112 and the sewage outlet 214 are alternately connected or disconnected, so that the clean water in the sewage chamber 213 is in a turbulent state. Compared with related technologies, the cleaning equipment 200 in the cleaning system 10 provided in this application can draw cleaning water from the water storage tank 111 into the sewage chamber through the suction port 211 and the suction channel 212 to clean the bottom of the cleaning equipment, the suction port 211, the suction channel 212 and the sewage chamber 213, and discharge it through the sewage port 214 and the drain port 112. Moreover, since the drain port 112 and the sewage port 214 are alternately connected or disconnected, the cleaning water in the sewage chamber 213 is in a turbulent state, which can deeply clean the sewage chamber 213, prevent dirt from remaining in the sewage chamber 213, and thus avoid the growth of bacteria and the generation of musty or foul odors in the sewage chamber 213.

[0022] Example 1 Base station 100 is an intelligent infrastructure. When cleaning equipment 200 is placed on base station 100, auxiliary operations such as self-cleaning, charging and water filling of cleaning equipment 200 can be realized. Cleaning equipment 200 can be floor scrubber, sweeping and mopping robot, etc.

[0023] The following description uses cleaning equipment 200 as a floor scrubber. Cleaning equipment 200 includes a main body 210 and a first switch door 230. The main body 210 has a suction port 211, a suction channel 212, a sewage chamber 213, and a sewage outlet 214 connected in sequence. A pneumatic power mechanism 220 is installed on the main body 210 and is used to draw air from the sewage chamber 213 to generate negative pressure in the sewage chamber 213. The first switch door 230 is installed on the main body 210 and is used to open or close the sewage outlet 214.

[0024] The main body 210 includes a cleaning module 217 and a handle module 218. The cleaning module 217 has a cleaning component 2171 on the side near the suction port 211. The cleaning component 2171 can be a roller brush or the like. The cleaning module 217 also has a clean water tank 2172 and a spray component connected to the clean water tank 2172. When the cleaning module 217 cleans the surface to be cleaned, the spray component is used to draw cleaning water from the clean water tank 2172 and spray the cleaning water onto the surface to be cleaned or the cleaning component 2171, so that the cleaning module 217 can deeply clean the surface to be cleaned.

[0025] The handle module 218 is rotatably mounted on the cleaning module 217 and forms a suction channel 212, a wastewater chamber 213, and a wastewater outlet 214. A pneumatic power mechanism 220 is mounted on the handle module 218 and communicates with both the wastewater chamber 213 and the outside environment, allowing the pneumatic power mechanism 220 to draw air from the wastewater chamber 213 and discharge it to the outside environment. A first switch door 230 is mounted on the handle module 218 near the wastewater outlet 214. When the cleaning module 217 cleans the surface to be cleaned, the first switch door 230 closes the wastewater outlet 214; when wastewater needs to be discharged from the wastewater chamber 213, the first switch door 230 opens the wastewater outlet 214.

[0026] The handle module 218 includes a first control component and a first storage component. The first storage component stores data, such as various software control programs, cleaning equipment modes, and / or parameters. Specifically, the program may include program code, which includes computer operation instructions. The first control component controls the operation of the cleaning equipment 200 and responds to user and third-party terminal commands through various software control programs stored in the first storage component. For example, the first control component is electrically connected to the cleaning component 2171, the spraying component, and the pneumatic power mechanism 220. The first control component can be used to control the cleaning component 2171, the spraying component, and the pneumatic power mechanism 220. It is understood that in some embodiments, the first control component is also electrically connected to the first opening / closing door 230, so that the first control component can also control the first opening / closing door 230.

[0027] The cleaning device 200 cleans the surface to be cleaned in the following way: the first control component controls the rotation of the cleaning component 2171, the spraying component sprays the cleaning liquid in the clean water tank 2172 onto the surface to be cleaned or the cleaning component 2171, and the gas power mechanism 220 draws air from the sewage chamber 213, thereby completing the cleaning of the surface to be cleaned and drawing the sewage generated after cleaning into the sewage chamber 213.

[0028] The handle module 218 has a first water level detection element installed in the sewage chamber 213, which is electrically connected to the first control component. The first water level detection element is used to detect the water level information of the sewage in the sewage chamber 213. For example, when the first water level detection element detects that the sewage chamber 213 is full, the first water level detection element generates an alert signal and transmits it to the first control component. The first control component controls the cleaning equipment 200 to stop working or controls the alert device to issue an alert. The alert device can be an indicator light or a horn to remind the user to place the cleaning equipment 200 on the base station 100 to drain the sewage in the sewage chamber 213.

[0029] The handle module 218 also includes a first wastewater detection element within the wastewater chamber 213, which is electrically connected to the first control component. The first wastewater detection element is used to detect the cleanliness of the clean water within the wastewater chamber 213. For example, it can detect the concentration of suspended particulate matter in the clean water within the wastewater chamber 213; a higher concentration of suspended particulate matter indicates lower cleanliness, and a lower concentration indicates higher cleanliness. Alternatively, it can also detect the light transmittance of the clean water within the wastewater chamber 213; higher light transmittance indicates higher cleanliness, and lower light transmittance indicates lower cleanliness.

[0030] The first wastewater detection device is also used to detect the degree of dirtiness of the wastewater in the wastewater chamber 213. For example, the first wastewater detection device is used to detect the concentration of suspended particulate matter in the wastewater in the wastewater chamber 213. The higher the concentration of suspended particulate matter in the wastewater in the wastewater chamber 213, the higher the degree of dirtiness of the wastewater in the wastewater chamber 213; the lower the concentration of suspended particulate matter in the wastewater in the wastewater chamber 213, the lower the degree of dirtiness of the wastewater in the wastewater chamber 213. As another example, the first wastewater detection device is used to detect the light transmittance of the wastewater in the wastewater chamber 213. The higher the light transmittance of the wastewater in the wastewater chamber 213, the lower the degree of dirtiness of the wastewater in the wastewater chamber 213; the lower the light transmittance of the wastewater in the wastewater chamber 213, the higher the degree of dirtiness of the wastewater in the wastewater chamber 213.

[0031] It is understandable that there is a correlation between dirtiness and cleanliness; that is, the higher the dirtiness, the lower the cleanliness, and vice versa. Therefore, the first wastewater detection device can detect both the cleanliness of the clean water in the wastewater chamber 213 and the dirtiness of the wastewater in the wastewater chamber 213.

[0032] The base station 100 includes a housing 110, which has a water storage tank 111 and a drain outlet 112. The water storage tank 111 is used to store clean water, and the volume of clean water stored in the water storage tank 111 is 4-5L.

[0033] The housing 110 has a support base 113 inside the water storage tank 111. The support base 113 forms a receiving interface 1131, which is connected to the drain outlet 112. When the cleaning equipment 200 cooperates with the base station 100, the cleaning module 217 is housed in the water storage tank 111 and submerged by the cleaning water in the water storage tank 111. It is understood that the circuitry inside the cleaning module 217 needs to be sealed to prevent the cleaning water in the water storage tank 111 from seeping into the circuitry of the cleaning module 217.

[0034] The handle module 218 is housed in the receiving interface 1131 on the side near the sewage outlet 214. When the first switch door 230 opens the sewage outlet 214, the sewage outlet 214 connects with the receiving interface 1131, allowing sewage in the sewage chamber 213 to be discharged sequentially through the sewage outlet 214, the receiving interface 1131, and the drain outlet 112. The receiving interface 1131 allows the support base 113 to both support the handle module 218 and limit its movement, preventing it from shifting.

[0035] The support base 113 is provided with a sealing element 1132 on the outer edge of the receiving interface 1131. The sealing element 1132 is used to seal the contact surface between the outer edge of the receiving interface 1131 and the main body 210. This can prevent sewage in the sewage chamber 213 from flowing out through the gap between the outer edge of the receiving interface 1131 and the main body 210, and also prevent air from entering the sewage chamber 213 through the gap between the outer edge of the receiving interface 1131 and the main body 210 when the gas power mechanism 220 draws air from the sewage chamber 213.

[0036] The enclosure 110 houses a second control component and a second storage component. The second storage component stores data, such as various software control programs, cleaning equipment modes, and / or parameters. Specifically, the programs may include program code, which includes computer operation instructions. The second control component controls the operation of the base station 100 and responds to user and third-party terminal commands through various software control programs stored in the second storage component.

[0037] The support base 113 is also provided with a first contact terminal 1133, which is electrically connected to the second control component. The handle module 218 is also provided with a second contact terminal 2181, which is electrically connected to the first control component. When the base station 100 cooperates with the cleaning device 200, the first contact terminal 1133 and the second contact terminal 2181 are electrically connected, thereby realizing the communication connection between the first control component and the second control component, and realizing the function of the base station 100 charging the cleaning device 200. It should be noted that in other embodiments, the first contact terminal 1133 and the second contact terminal 2181 may not be provided, and the first control component and the second control component may communicate via Bluetooth or WIFI, etc., and the base station 100 may charge the cleaning device 200 wirelessly.

[0038] The base station 100 also includes a water inlet pipe, a water injection valve, and a water inlet 114. The water inlet pipe is connected to an external water pipe or faucet. The water injection valve can be a solenoid valve or a proportional valve, etc., and is connected to both the water inlet and the water inlet pipe. The water injection valve is also electrically connected to the second control component. The water injection valve is used to control the flow rate of clean water flowing into the water inlet from the water inlet pipe according to the instructions of the second control component. The water inlet 114 is located in the water storage tank 111. The clean water tank 2172 has a water inlet 2173, which is connected to the clean water tank 2172. A valve is installed inside the water inlet 2173. When water is added to the clean water tank 2172 through the water inlet 2173, the valve opens the water inlet 2173; after the water is added, the valve closes the water inlet 2173. When the cleaning device 200 is connected to the base station 100, the water inlet 114 is connected to the water filling port 2173 and the valve of the water filling port 2173 is opened, thereby connecting the water inlet 114 to the clean water tank 2172 through the water filling port 2173 to inject clean water into the clean water tank 2172. It is understood that the clean water tank 2172 is equipped with a water level detector, which is used to detect the water level of the clean water in the clean water tank 2172. When the water level detector detects that the clean water in the clean water tank 2172 has reached full, the water level detector generates a signal and transmits it to the second control component through the first control component. The second control component generates a control command to close the water inlet valve. It is also understood that the water level detector can detect when the clean water in the clean water tank 2172 is low, to remind the user to add water to the clean water tank 2172. The water level detector can be any device capable of detecting the water level in the water storage tank 111, such as a float sensor, infrared sensor, photoelectric liquid level sensor, capacitive liquid level sensor, or ultrasonic liquid level sensor.

[0039] The housing 110 also has a water inlet 115, which is connected to the water storage tank 111. The base station 100 also includes a water inlet valve, which can be a solenoid valve or a proportional valve, etc. The water inlet valve is connected to the water inlet 115 and the water inlet pipeline respectively. The water inlet valve is used to control the flow rate of clean water flowing into the water inlet from the water inlet pipeline according to the instructions of the second control component, that is, to control the flow rate of clean water flowing into the water storage tank 111.

[0040] The base station 100 also includes a second water level detection device, which is installed in the housing 110 and electrically connected to the second control component. The second water level detection device is used to detect the water level in the water storage tank 111. When the water level in the water storage tank 111 reaches a first preset position, the second water level detection device generates a first signal and transmits the first signal to the second control component. The second control component then closes the inlet valve to stop water from being added to the water storage tank 111. It is understood that the second water level detection device can be any device capable of detecting the water level in the water storage tank 111, such as a float sensor, infrared sensor, photoelectric liquid level sensor, capacitive liquid level sensor, or ultrasonic liquid level sensor.

[0041] The housing 110 also has a water outlet 116, which is connected to the water storage tank 111 and is used to discharge the sewage in the water storage tank 111.

[0042] The base station 100 also includes a centrifugal water pump and a water outlet pipe. The centrifugal water pump is connected to both the water outlet 116 and the water outlet pipe, which is connected to a floor drain or sewer. This allows wastewater in the water storage tank 111 to be discharged into the floor drain or sewer using a centrifugal method. It is understood that the water outlet pipe can be connected to a sewage outlet, so that wastewater from the cleaning equipment 200 and the water storage tank 111 can be discharged into the floor drain or sewer through the same wastewater pipe.

[0043] The first switch door 230 includes a first control valve, which can be a solenoid valve or a proportional valve. The first control valve is connected to the sewage outlet 214. The first control valve is used to alternately open or close the sewage outlet 214 according to the control command, so that the sewage outlet 112 and the sewage outlet 214 are alternately connected or disconnected.

[0044] In this embodiment, the cleaning system 10 cleans the cleaning equipment 200 as follows: After the main body 210 and the box 110 cooperate and the first control valve is opened to discharge the sewage in the sewage chamber 213 through the sewage outlet 214, clean water is injected into the water storage tank 111 and submerges the suction port 211. The gas power mechanism 220 is controlled to draw air from the sewage chamber 213, and the first control valve is controlled to alternately open or close the sewage outlet 214. When the first control valve closes the sewage outlet 214, the gas power mechanism 220 draws air from the sewage chamber 213, and the clean water in the water storage tank 111 flows into the sewage chamber 213 through the suction port 211 and the suction channel 212. The water flow will also drive the cleaning component 2171 to rotate, thereby cleaning the cleaning component 2171. When the first control valve opens the sewage outlet 214, the gas power mechanism 220 draws air from the sewage chamber 213. Not only will the clean water in the water storage tank 111 flow into the sewage chamber 213 through the suction port 211 and the suction channel 212, but air will also enter the sewage chamber 213 through the drain port 112 and the sewage outlet 214. This will cause the clean water in the sewage chamber 213 to be in a turbulent state, thereby enabling deep cleaning of the sewage chamber 213, preventing dirt from remaining in the sewage chamber 213, and thus avoiding the growth of bacteria and the generation of musty or foul odors in the sewage chamber 213. The opening and closing times of the first control valve through the sewage outlet 214 can be designed according to specific circumstances, such as the size of the sewage chamber 213 or the water level of the clean water in the sewage chamber 213.

[0045] The gas power mechanism 220 is also used to inflate the sewage chamber 213 with air, thereby drying the cleaned cleaning parts 2171, the suction port 211, the suction channel 212 and the sewage chamber 213 after cleaning.

[0046] When the gas power mechanism 220 inflates the sewage chamber 213, the first control valve is used to open the sewage outlet 214 according to the control command, so that the receiving port 1131 and the sewage outlet 112 can also be dried.

[0047] The cleaning device 200 also includes a heating element, which is installed on the gas power mechanism 220 or the handle module 218 and is used to heat the air to be filled into the sewage chamber. This can accelerate the drying speed of the cleaned cleaning component 2171, the suction port 211, the suction channel 212, the sewage chamber 213 receiving interface 1131, and the sewage outlet 112 after cleaning, and can also disinfect the cleaned cleaning component 2171, the suction port 211, the suction channel 212, the sewage chamber 213, and the sewage outlet 112 after cleaning.

[0048] Example 2 The difference between Example 2 and Example 1 is as follows: The first switch door 230 is movably mounted on the handle module 218 to open or close the sewage outlet 214. For example, the first switch door 230 is rotatably mounted on the handle module 218, and a reset member is provided between the first switch door 230 and the handle module 218. Without external force, the first switch door 230 closes the sewage outlet 214, and with external force, the first switch door 230 opens the sewage outlet 214.

[0049] The base station 100 also includes a water leakage chamber 120, a second switch door 130, and a door opening component 140. The water leakage chamber 120 is connected to the support base 113 and forms a water leakage cavity 121 and a drain hole 122. The water leakage cavity 121 is connected to the receiving interface 1131, and the drain hole 122 is connected to both the water leakage cavity 121 and the sewage outlet 112. It should be noted that the water leakage chamber 120 can be integrally formed with the support base 113.

[0050] The door opening component 140 is fixed to the drain chamber 120. When the main body 210 is engaged with the housing 110, the door opening component 140 drives the first switch door 230 to open the sewage outlet 214, thereby connecting the sewage outlet 214 with the drain chamber 120. It should be noted that in other embodiments, the door opening component 140 can also be fixed to the support base 113. Moreover, the drain chamber 120 can be omitted, and the second control valve can be directly connected to the drain outlet 112. The second control valve is used to alternately open or close the drain outlet 112 according to control commands.

[0051] The second switch door 130 includes a second control valve, which can be a solenoid valve or a proportional valve. The second control valve is installed in the leakage chamber 120 and communicates with the drain hole 122. The second control valve is used to alternately open or close the drain hole 122 according to the control command, so that the sewage outlet 112 and the sewage outlet 214 are alternately in a connected or disconnected state.

[0052] In this embodiment, the cleaning principle of the cleaning system 10 on the cleaning equipment 200 is as follows: When the main body 210 and the box 110 are in cooperation, the door opening component 140 drives the first switch door 230 to open the sewage outlet 214 and controls the second control valve to open the drain hole 122 to discharge the sewage in the sewage chamber 213. Then, clean water is injected into the water storage tank 111 and submerges the sewage suction port 211. The gas power mechanism 220 is controlled to suck air from the sewage chamber 213 and the second control valve is controlled to alternately open or close the drain hole 122. When the second control valve closes the drain hole 122, the pneumatic mechanism 220 draws air from the sewage chamber 213, causing clean water in the water storage tank 111 to flow into the sewage chamber 213 through the suction port 211 and suction channel 212. The water flow also drives the cleaning component 2171 to rotate, thus cleaning the cleaning component 2171. When the second control valve opens the drain hole 122, the pneumatic mechanism 220 draws air from the sewage chamber 213, causing not only clean water in the water storage tank 111 to flow into the sewage chamber 213 through the suction port 211 and suction channel 212, but also air to enter the sewage chamber 213 through the drain port 112, drain hole 122, leakage chamber 121, and sewage passage 214. This causes the clean water in the sewage chamber 213 to churn, resulting in a deep cleaning of the sewage chamber 213, preventing dirt from remaining inside and thus avoiding bacterial growth and musty or foul odors.

[0053] Example 3 The difference between Example 3 and Example 2 is as follows: The drain hole 122 is provided on the side wall of the water leakage chamber 120. The second switch door 130 is rotatably installed on the side of the water leakage chamber 120 away from the water leakage cavity 121. The second switch door 130 alternately opens or closes the drain hole 122 under the action of the pneumatic power mechanism 220 and the gravity of the clean water, so that the sewage outlet 112 and the sewage outlet 214 are alternately in a connected or disconnected state.

[0054] In this embodiment, the cleaning principle of the cleaning system 10 for the cleaning equipment 200 is as follows: When the main body 210 and the box 110 are in cooperation, the door opening component 140 drives the first switch door 230 to open the sewage outlet 214. Under the action of gravity, the sewage in the sewage chamber 213 flows to the sewage outlet 214, the water leakage chamber 121 and the drain hole 122 and flushes open the second switch door 130 and is discharged through the sewage outlet 112. Clean water is injected into the water storage tank 111 and submerges the sewage suction port 211. The gas power mechanism 220 is controlled to suck air from the sewage chamber 213. As the gas-powered mechanism 220 draws air from the sewage chamber 213, the clean water in the water storage tank 111 flows into the sewage chamber 213 through the suction port 211 and the suction channel 212. The water flow drives the cleaning component 2171 to rotate, thereby cleaning the cleaning component 2171. It also causes the second switch door 130 to rotate closer to the drain chamber 120 to close the drain hole 122. When the negative pressure generated by the gas-powered mechanism 220 drawing air from the sewage chamber 213 is less than the weight of the clean water in the sewage chamber 213, the clean water flows towards the sewage outlet 214, the drain chamber 121, and the drain hole 122 under the action of gravity and opens the second switch door. 130, so that the drain outlet 112 and the sewage outlet 214 are in a connected state; when the negative pressure generated by the gas power mechanism 220 drawing air from the sewage chamber 213 is greater than the weight of the clean water in the sewage chamber 213, air will enter the sewage chamber 213 from the drain outlet 112, drain hole 122, leakage chamber 121 and sewage outlet 214, and drive the second switch door 130 to close the drain hole 122, so that the clean water in the sewage chamber 213 will be in a turbulent state, thereby deeply cleaning the sewage chamber 213, preventing dirt from remaining in the sewage chamber 213, thereby avoiding the growth of bacteria and the generation of musty odors in the sewage chamber 213.

[0055] Example 4 The difference between Example 4 and Example 1 is as follows: The first switch door 230 is movably mounted on the handle module 218 to open or close the sewage outlet 214. For example, the first switch door 230 is rotatably mounted on the handle module 218, and a reset member is provided between the first switch door 230 and the handle module 218. Without external force, the first switch door 230 closes the sewage outlet 214, and with external force, the first switch door 230 opens the sewage outlet 214.

[0056] The base station 100 also includes a switch (which can be modified based on the door opening component 140) and a drive assembly. The switch is slidably mounted on the support base 113 in the vertical direction. The drive assembly is fixed to the support base 113 and is driven by the switch to drive the switch to reciprocate in the vertical direction. The drive assembly may include a pneumatic cylinder or a hydraulic cylinder, which is fixed to the support base 113, and the movable rod of the pneumatic cylinder or hydraulic cylinder is fixedly connected to the switch. The drive assembly may also include a motor and a transmission component, which are driven by the output shaft of the motor and the switch, respectively.

[0057] When the main body 210 and the housing 110 are engaged, the switch element reciprocates in the vertical direction, driving the first switch door 230 to alternately open or close the sewage outlet 214, so that the sewage outlet 112 and the sewage outlet 214 are alternately connected or disconnected. It should be noted that in other embodiments, the switch element can also be rotatably mounted on the support base 113, and the switch element is cam-shaped. The drive assembly is used to drive the switch element to rotate in the vertical plane, so that the switch element drives the first switch door 230 to alternately open or close the sewage outlet 214 during the rotation.

[0058] In this embodiment, the cleaning principle of the cleaning system 10 to the cleaning equipment 200 is as follows: After the main body 210 and the box 110 are engaged, the control switch drives the first switch door 230 to open the sewage outlet 214 to discharge the sewage in the sewage chamber 213. Then, clean water is injected into the water storage tank 111 and submerges the sewage inlet 211. The control gas power mechanism 220 is controlled to draw air from the sewage chamber 213, and the control switch drives the first switch door 230 to alternately open or close the sewage outlet 214. When the first switch door 230 closes the sewage outlet 214, the gas power mechanism 220 draws air from the sewage chamber 213, and the clean water in the water storage tank 111 flows into the sewage chamber 213 through the suction port 211 and the suction channel 212. The water flow will also drive the cleaning component 2171 to rotate, thereby cleaning the cleaning component 2171. When the first switch door 230 opens the sewage outlet 214, the gas power mechanism 220 draws air from the sewage chamber 213, and not only will the clean water in the water storage tank 111 flow into the sewage chamber 213 through the suction port 211 and the suction channel 212, but air will also enter the sewage chamber 213 through the drain port 112 and the sewage outlet 214. This will cause the clean water in the sewage chamber 213 to be in a turbulent state, thereby deeply cleaning the sewage chamber 213, preventing dirt from remaining in the sewage chamber 213, and thus avoiding the growth of bacteria and the generation of musty or foul odors in the sewage chamber 213.
