[0001] This invention relates to the field of lawnmower base station technology, and in particular to a lawnmower cleaning base station and its control method. Background Technology

[0011] In some embodiments, the lawnmower cleaning base station further includes a first pump body connected to the water supply pipeline; And / or, the first valve body is a control valve or a check valve.
[0012] In some embodiments, the lawnmower cleaning base station also includes a base and a wastewater recycling assembly; The base is provided with a water collection tank, and the sewage recovery assembly includes a sewage recovery pipeline and a second pump body.

[0017] The lawnmower cleaning base station and its control method provided by this invention utilize a pressure control device connected to a water storage tank, which increases the air pressure within the tank. When water needs to be supplied to the sprinkler system, the pressure control device increases the air pressure in the water storage chamber, creating positive pressure within the tank. Water from the tank then flows into the sprinkler system under the pressure difference, thus supplying water to the sprinkler system and cleaning the lawnmower. By increasing the air pressure within the tank, the water storage tank can supply water to the sprinkler system without requiring it to be positioned high, avoiding any impact on water pressure. Furthermore, energy consumption is reduced, and noise and vibration are minimized. Therefore, the lawnmower cleaning base station provided by this application reduces energy consumption, decreases noise and vibration when supplying water to the sprinkler system, and does not increase the overall height of the equipment.

[0021] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.
[0025] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.
[0026] like Figures 1 to 3 As shown, the lawnmower cleaning base station 100 provided in this embodiment of the invention includes a spraying device 10, a water storage tank 20, an air pressure control device 30, and a control module. The spraying device 10 is used to spray cleaning water onto the lawnmower. The water storage tank 20 is connected to the spraying device 10. The air pressure control device 30 is connected to the water storage tank 20 and is used to increase the air pressure in the water storage tank 20. The air pressure control device 30 is electrically connected to the control module.
[0027] By installing a pressure control device 30 connected to the water storage tank 20, the pressure inside the water storage tank 20 can be increased. When water needs to be supplied to the sprinkler device 10, the pressure control device 30 can increase the pressure in the water storage chamber, generating positive pressure in the water storage tank 20. Water in the water storage tank 20 can then flow into the sprinkler device 10 under the pressure difference, thus supplying water to the sprinkler device 10 and cleaning the lawnmower. Specifically, by increasing the pressure inside the water storage tank 20, the pressure control device 30 supplies water to the sprinkler device 10. This eliminates the need for the water storage tank 20 to be positioned high, avoiding any impact on water pressure, and also reduces energy consumption, noise, and vibration. By electrically connecting the pressure control device 30 to the control module, the intelligence of the pressure control device 30 in controlling the water supply from the water storage tank 20 to the sprinkler device 10 can be improved.
[0028] Therefore, the lawnmower cleaning base station 100 provided in this application reduces energy consumption, decreases noise and vibration when supplying water to the sprinkler device 10, and does not increase the overall height of the equipment.
[0029] Please see Figure 1 and Figure 4The air pressure control device 30 includes an air pump 31, which has an inlet end 311 and an outlet end 312. The outlet end 312 is configured to connect to the water storage tank 20. Gas can enter the air pump 31 through the inlet end 311 and exit through the outlet end 312. Since the outlet end 312 is connected to the water storage tank 20, the gas exiting from the outlet end 312 can enter the water storage tank 20, thereby increasing the air pressure inside the water storage tank 20. This allows water in the water storage tank 20 to enter the spray device 10 under the influence of the air pressure difference.
[0030] In some embodiments, the air pump 31 is a low-noise air pump. Specifically, the low-noise air pump includes, but is not limited to, a scroll air pump, a linear drive air pump, and a diaphragm air pump. This helps to reduce the noise and vibration of the lawnmower cleaning base station 100 during operation, improving the user comfort and stability of the base station.
[0031] In some embodiments, the air pressure control device 30 further includes a ventilation assembly connected between the air pump 31 and the water storage tank 20. The ventilation assembly is used at least to control the air outlet 312 to be connected to the water storage tank 20. This enables communication between the air outlet 312 and the water storage tank 20.
[0032] In some embodiments, the ventilation assembly is used to control the air inlet 311 and the air outlet 312 to be selectively connected to the water storage tank 20. In this way, the air inlet 311 or the air outlet 312 of the air pump 31 can be flexibly connected to the water storage tank 20 according to different needs.
[0033] In practical applications, when the ventilation assembly controls the air outlet 312 to be connected to the water storage tank 20, gas is discharged from the air outlet 312 and enters the water storage tank 20 under the action of the air pump 31, thereby generating positive pressure in the water storage tank 20. When the ventilation assembly controls the air inlet 311 to be connected to the water storage tank 20, gas in the water storage tank 20 flows into the air pump 31 from the air inlet 311 under the action of the air pump 31, thereby generating negative pressure in the water storage tank 20.
[0034] When positive pressure is generated in the water storage tank 20, the water in the water storage tank 20 can enter the sprinkler device 10 under the action of pressure difference, thereby supplying water to the sprinkler device 10; when negative pressure is generated in the water storage tank 20, the water outside the water storage tank 20 can enter the water storage tank 20 under the action of pressure difference, thereby filling the water storage tank 20. Therefore, the lawnmower cleaning base station 100 provided in this application, through the cooperation of the air pressure control device 30 and the water storage tank 20, can continuously supply water to the sprinkler device 10.
[0035] Of course, as an alternative technical solution, the ventilation component can also be set up to control the connection and disconnection between the air outlet 312 and the water storage tank 20.
[0036] In some embodiments, the ventilation assembly is also used to control both the air inlet 311 and the air outlet 312 to be disconnected from the water storage tank 20. Specifically, when it is not necessary to further increase or decrease the air pressure inside the water storage tank 20, both the air inlet 311 and the air outlet 312 can be controlled to be disconnected from the water storage tank 20 to stop further increasing or decreasing the air pressure inside the water storage tank 20. It is understood that in other embodiments, when it is not necessary to further increase or decrease the air pressure inside the water storage tank 20, this can also be achieved by turning off the air pump 31.
[0037] Please see Figures 4 to 6 The ventilation assembly includes a ventilation valve 32 and a drive device 33. The ventilation valve 32 includes an air inlet 3211, an air outlet 3212, a first guide port 3221, and a second guide port 3222. The air outlet 3212 connects to the air inlet 311, and the air inlet 3211 connects to the air outlet 312. The first guide port 3221 connects to the water storage tank 20, and the second guide port 3222 connects to the outside environment or external components. The external components can be a box or housing.
[0038] The ventilation valve 32 has a first state, a second state, and a third state. When the ventilation valve 32 is in the first state, the air outlet 3212 is connected to the first conductive port 3221, and the air inlet 3211 is connected to the second conductive port 3222. At this time, the air inlet 311 of the air pump 31 is connected to the water storage tank 20. When the ventilation valve 32 is in the second state, the air outlet 3212 is connected to the second conductive port 3222, and the air inlet 3211 is connected to the first conductive port 3221. At this time, the air outlet 312 of the air pump 31 is connected to the water storage tank 20. When the ventilation valve 32 is in the third state, both the air inlet 3211 and the air outlet 3212 are closed, or both the first conductive port 3221 and the second conductive port 3222 are closed. At this time, the ventilation valve 32 is not conductive, and both the air inlet 311 and the air outlet 312 of the air pump 31 are disconnected from the water storage tank 20. The drive unit 33 is used to drive the air exchange valve 32 to switch between the first state, the second state, and the third state. The drive unit 33 is electrically connected to the control module.
[0039] In a specific application, when the spraying device 10 cleans the lawnmower located at the base station, the air exchange valve 32 is in the second state, and the air pump 31 is turned on. Under the action of the air pump 31, the external gas or the gas in the external components flows into the water storage tank 20 through the second guide port 3222, the air outlet 3212, the air inlet 311, the air outlet 312, the air inlet 3211 and the first guide port 3221 in sequence, thereby generating positive pressure in the water storage tank 20. As a result, the water in the water storage tank 20 flows into the spraying device 10 from the outlet under the action of the pressure difference, and is sprayed onto the lawnmower by the spraying device 10.
[0040] When the water in the water storage tank 20 is used up or falls below the minimum water level, the air exchange valve 32 is set to the first state, and the air pump 31 is turned on. Under the action of the air pump 31, the gas in the water storage tank 20 flows to the outside or external components through the first guide port 3221, the air outlet 3212, the air inlet 311, the air outlet 312, the air inlet 3211 and the second guide port 3222 in sequence, thereby generating negative pressure in the water storage tank 20. This causes the water outside the water storage tank 20 to flow into the water storage tank 20 under the action of the pressure difference, thus realizing the injection of water into the water storage tank 20.
[0041] During the process of filling the water storage tank 20, when the water level in the water storage tank 20 reaches the preset level, the air pump 31 can be turned off, or the air exchange valve 32 can be set to the third state, so that the filling of water into the water storage tank 20 stops after the pressure difference inside and outside the water storage tank 20 disappears. Alternatively, if the water storage tank 20 is set at a higher position, when water needs to be supplied to the spray device 10, the air exchange valve 32 can be set to the third state, and the water storage tank 20 can be connected to the spray device 10, so that the water in the water storage tank 20 flows into the spray device 10 under the action of gravity.
[0042] By setting up an air exchange valve 32, an air pump 31, and a drive device 33, negative or positive pressure can be generated in the water storage tank 20. This eliminates the need for excessive valve bodies, thereby simplifying the base station structure, reducing space occupation, saving costs, improving the overall reliability of the base station system, and reducing the risk of air leakage.
[0043] Please see Figures 4 to 8 The ventilation valve 32 includes a first valve body 321 and a second valve body 322, with the first valve body 321 movably connected to the second valve body 322. An air inlet 3211 and an air outlet 3212 are both located on the first valve body 321, and a first guide port 3221 and a second guide port 3222 are both located on the second valve body 322. A driving device 33 drives one of the first valve body 321 and the second valve body 322 to move, thereby switching the ventilation valve 32 between a first state, a second state, and a third state.
[0044] In specific applications, by driving the first valve body 321 or the second valve body 322 to move, the air inlet 3211 and the air outlet 3212 provided on the first valve body 321 can move relative to the first guide port 3221 and the second guide port 3222 provided on the second valve body 322, thereby realizing the switching of the state of the air exchange valve 32.
[0045] In some embodiments, the first valve body 321 and the second valve body 322 are arranged opposite to each other. The driving device 33 drives the first valve body 321 or the second valve body 322 to rotate around the central axis M of the ventilation valve 32, so that the ventilation valve 32 switches between a first state and a second state. The distances from the air inlet 3211, the air outlet 3212, the first guide port 3221, and the second guide port 3222 to the central axis M of the ventilation valve 32 are the same. This arrangement allows the ventilation valve 32 to switch between a first state, a second state, and a third state by driving the first valve body 321 or the second valve body 322 to rotate around the central axis M of the ventilation valve 32. The structure is simple and occupies little space. In this embodiment, the driving device 33 drives the first valve body 321 to rotate around the central axis M of the ventilation valve 32.
[0046] It is understood that in other embodiments, the driving device 33 may also drive one of the first valve body 321 and the second valve body 322 to move relative to the other in other ways (such as sliding) to achieve the switching of the state of the air exchange valve 32.
[0047] In some embodiments, please refer to Figure 7 and Figure 8 The lines connecting the air inlet 3211 and the air outlet 3212, as well as the lines connecting the first guide port 3221 and the second guide port 3222, all pass through the central axis M of the air exchange valve 32. Thus, when one of the air inlet 3211 and the air outlet 3212 is directly opposite one of the first guide port 3221 and the second guide port 3222, driving the first valve body 321 to rotate 180° can switch between the first and second states. Driving the first valve body 321 to rotate more or less than 180° can switch between the first state, the second state, and the third state.
[0048] In practical applications, the first valve body 321 can be driven to rotate 180° clockwise or 180° counterclockwise to achieve alternating switching between the first and second states. Alternatively, the first valve body 321 can be driven to rotate 180° in both directions to achieve alternating switching between the first and second states. Similarly, by driving the first valve body 321 to rotate clockwise, counterclockwise, or repeatedly in both directions by more or less than 180°, switching between the first or second state and the third state can be achieved. Clockwise rotation can be set as positive rotation, and counterclockwise rotation can also be set as positive rotation.
[0049] It is understood that in other embodiments, the arrangement of the air inlet 3211 and the air outlet 3212, as well as the arrangement of the first guide port 3221 and the second guide port 3222, may also adopt other methods.
[0050] Please see Figure 7 and Figure 8 The ventilation valve 32 also includes a first air guide pipe 323 and a second air guide pipe 324, both of which are connected between the first valve body 321 and the second valve body 322. Both the first air guide pipe 323 and the second air guide pipe 324 are fixedly connected to the first valve body 321. The first air guide pipe 323 connects one of the first through-port 3221 and the second through-port 3222 to the air outlet 3212, and the second air guide pipe 324 connects the other of the first through-port 3221 and the second through-port 3222 to the air inlet 3211.
[0051] It is understood that in other embodiments, the air exchange valve 32 may not be provided with the first air guide pipe 323 and the second air guide pipe 324. When adopting this technical solution, the first valve body 321 and the second valve body 322 can be provided in close contact, the air outlet 3212 is directly connected to one of the first guide port 3221 and the second guide port 3222, and the air inlet 3211 is directly connected to the other of the first guide port 3221 and the second guide port 3222.
[0052] Alternatively, in other embodiments, the first air guide pipe 323 and the second air guide pipe 324 may be fixedly connected to the second valve body 322. The first air guide pipe 323 is used to connect one of the air outlet 3212 and the air inlet 3211 to the first connecting port 3221, and the second air guide pipe 324 is used to connect the other of the air outlet 3212 and the air inlet 3211 to the second connecting port 3222.
[0053] In some embodiments, the first air guide pipe 323 includes a first conduit 3231 and a first seal 3232. The first seal 3232 is sleeved on the outer periphery of the first conduit 3231, and the length of the first seal 3232 is slightly greater than the length of the first conduit 3231. The second air guide pipe 324 includes a second conduit 3241 and a second seal 3242. The second seal 3242 is sleeved on the outer periphery of the second conduit 3241, and the length of the second seal 3242 is slightly greater than the length of the second conduit 3241. Both the first conduit 3231 and the second conduit 3241 are fixedly connected to the first valve body 321.
[0054] Please see Figure 3 and Figure 9The lawnmower cleaning base station 100 also includes a first valve body 41 and a water supply pipe 42. The water supply pipe 42 is connected between the water storage tank 20 and the spray device 10, and the first valve body 41 is connected to the water supply pipe 42. The first valve body 41 is used to control the on / off state of the water supply pipe 42. In specific applications, when cleaning the lawnmower located at the base station, the first valve body 41 controls the water supply pipe 42 to be open, and the water storage tank 20 can supply water to the spray device 10 through the water supply pipe 42; when not cleaning the lawnmower located at the base station, the first valve body 41 controls the water supply pipe 42 to be closed.
[0055] In some embodiments, the first valve body 41 is a one-way valve, such as a duckbill valve. In specific applications, the one-way valve is located at the outlet of the water storage tank 20. It is understood that in other embodiments, the first valve body 41 may also be a control valve, such as a solenoid valve, which is electrically connected to the control module.
[0056] In some embodiments, multiple sprinkler devices 10 are provided, and the lawnmower cleaning base station 100 also includes a water distribution box 43 and multiple water supply branches 44. A water supply pipe 42 is connected between the water storage tank 20 and the water distribution box 43, and each sprinkler device 10 is connected to the water distribution box 43 through a water supply branch 44. Of course, in other embodiments, the water distribution box 43 and the water supply branches 44 may not be provided, and the water supply pipe 42 may be directly connected to the water storage tank 20 and the sprinkler device 10.
[0057] In some embodiments, the lawnmower cleaning base station 100 further includes a first water level detection device 45, which is disposed inside the water storage tank 20. By setting the first water level detection device 45, the water level in the water storage tank 20 can be detected, thereby determining whether there is enough water in the water storage tank 20 to supply water to the sprinkler device 10 when the water storage tank 20 supplies water to the sprinkler device 10, or determining whether it is necessary to stop water filling when filling the water storage tank 20.
[0058] In some embodiments, the first water level detection device 45 is electrically connected to the control module. In specific applications, the first water level detection device 45 transmits the detection result to the control module, which can then determine the next step based on the detection result.
[0059] In some embodiments, the first water level detection device 45 is a water level sensor or a pressure sensor.
[0060] In some embodiments, the lawnmower cleaning base station 100 further includes a pre-cleaning pressure adjustment module, which is used to receive a pre-cleaning request to enable the control module to activate the air pressure control device 30.
[0061] The pre-regulation pressure module is electrically connected to the control module, transmitting received signals to it. Based on these signals, the control module activates the air pressure control device 30. This allows the control module to pre-activate the air pressure control device 30 before the lawnmower reaches the lawnmower cleaning station 100. Consequently, upon arrival at the cleaning station 100, the air pressure in the water tank 20 has reached the required value (at which the first valve 41 opens, allowing water from the tank 20 to flow into the spray device 10 under pressure difference). Therefore, when the lawnmower arrives at the cleaning station 100, the water tank 20 immediately supplies water to the spray device 10 to clean the lawnmower, saving the time required for air pressure buildup.
[0062] In some embodiments, the pre-cleaning pressure adjustment module is located at the lawnmower cleaning base station 100. Specifically, the pre-cleaning pressure adjustment module can be located in the water tank 20, or the base 50 or water supply tank 80 described below. This allows the user to send a pre-cleaning request at the lawnmower cleaning base station 100.
[0063] It is understood that in other embodiments, the pre-cleaning pressure adjustment module can also be located on a mobile terminal. The mobile terminal can be a mobile phone or a computer, etc. This allows the user to remotely send a pre-cleaning request.
[0064] In some embodiments, the lawnmower cleaning base station 100 further includes a first pump body 46 connected to a water supply line 42. This, with the assistance of the first pump body 46, increases the water supply capacity of the water tank 20 to the sprinkler system 10. Since the water supply from the water tank 20 to the sprinkler system 10 can be achieved solely by a pressure control device 30, the first pump body 46 can be configured as a small water pump to assist the pressure control device 30, thereby reducing noise and vibration compared to existing solutions. Of course, in other embodiments, the lawnmower cleaning base station 100 may not include the first pump body 46.
[0065] Please see Figure 1 ,as well as Figures 10 to 12 The lawnmower cleaning base station 100 also includes a base 50 and a wastewater recycling component 60. The base 50 is provided with a water collection tank 51. The wastewater recycling component 60 includes a wastewater recycling pipeline 61 and a second pump body 62. The wastewater recycling pipeline 61 is connected between the water collection tank 51 and the water storage tank 20, and the second pump body 62 is connected to the wastewater recycling pipeline 61.
[0066] When the lawnmower returns to the lawnmower cleaning base station 100 for cleaning, it moves onto the base 50. Wastewater generated during cleaning of the lawnmower on the base 50 collects in a collection tank 51. A wastewater recovery pipe 61 connects the collection tank 51 and the storage tank 20, allowing the wastewater collected in the collection tank 51 to be transported to the storage tank 20. This prevents wastewater from being discharged into the surrounding environment of the base station, thus reducing the burden of secondary cleaning for users.
[0067] In a specific application, when cleaning the lawnmower located on the base 50, the second pump body 62 is turned on. Under the action of the second pump body 62, the sewage in the water collection tank 51 is transported to the water storage tank 20 to realize the recycling of sewage.
[0068] Please see Figure 12 The wastewater recovery assembly 60 also includes a second valve body 63 and / or a third valve body 64, which are connected to the wastewater recovery pipeline 61 and located between the second pump body 62 and the water storage tank 20. The second valve body 63 is a solenoid valve, and the third valve body 64 is a check valve. By setting the solenoid valve and / or the check valve, the on / off state of the wastewater recovery pipeline 61 can be controlled so that the wastewater recovery pipeline 61 is only open when wastewater recovery is performed, thereby preventing water in the water storage tank 20 from flowing back into the collection tank 51.
[0069] Please see Figure 1 and Figure 11 The lawnmower cleaning station 100 also includes a filter device 70, which is connected to the base 50 and located at the opening of the water collection tank 51. In this way, the wastewater generated during the cleaning process is filtered by the filter device 70 and collected in the water collection tank 51, preventing grass clippings, solid particles and other solid impurities from entering the water collection tank 51, thus achieving the separation of solid impurities and wastewater.
[0070] In some embodiments, the filter device 70 is detachably connected to the base 50. This allows the filter device 70 to be removed for cleaning, maintenance, or replacement after a period of use, thus preventing clogging.
[0071] In some embodiments, the lawnmower cleaning base station 100 further includes a second water level detection device 52, which is disposed within the water collection tank 51. This allows the second water level detection device 52 to detect the water level within the water collection tank 51. The water level in the water collection tank 51 can be used to determine the water volume in the water storage tank 20 or whether wastewater recycling has been activated. For example, if the water level in the water collection tank 51 determines the water volume in the water storage tank 20, and after cleaning the lawnmower has stopped, and during wastewater recycling, the second water level detection device 52 detects that the water level in the water collection tank 51 remains unchanged for a certain period, it can be determined that the water volume in the water storage tank 20 has reached its maximum level.
[0072] Please see Figure 1 and Figure 2 The lawnmower cleaning base station 100 also includes a water supply tank 80 and a water delivery pipe 90, with the water delivery pipe 90 connecting the water supply tank 80 and the water storage tank 20. When the water in the water storage tank 20 is used up or falls below the minimum water level, the water in the water supply tank 80 can flow into the water storage tank 20 through the water delivery pipe 90 under the action of pressure difference, thus filling the water storage tank 20 with water.
[0073] This invention also provides a control method for a lawnmower cleaning base station 100, used to control the aforementioned lawnmower cleaning base station 100; the control method includes: The control module controls the air pressure control device to deliver gas into the water storage tank to generate positive pressure inside the tank. Under the action of the pressure difference, the water in the tank flows from the tank into the spray device.
[0074] In this way, the water storage tank 20 supplies water to the spray device 10.
[0075] In some embodiments, the lawnmower cleaning base station 100 further includes a first valve body 41 and a water supply pipe 42, the water supply pipe 42 being connected between the water storage tank 20 and the spray device 10, and the first valve body 41 being connected to the water supply pipe 42; the first valve body 41 is a control valve, and the control method further includes, before the step of the control module controlling the air pressure control device 30 to deliver gas into the water storage tank 20: The control module controls the first valve to open, connecting the water storage tank and the spray device.
[0076] In some embodiments, the lawnmower cleaning base station 100 further includes a first valve body 41 and a water supply pipe 42. The water supply pipe 42 is connected between the water storage tank 20 and the spray device 10, and the first valve body 41 is connected to the water supply pipe 42. The first valve body 41 is a one-way valve. The control module controls the air pressure control device 30 to deliver gas into the water storage tank 20 to generate positive pressure in the water storage tank 20. The step of water in the water storage tank 20 flowing into the spray device 10 from the water storage tank 20 under the action of the pressure difference includes: The control module controls the air pressure control device to deliver gas into the water storage tank to generate positive pressure in the water storage tank. When the positive pressure in the water storage tank reaches the preset positive pressure value, the first valve body opens automatically under the action of pressure difference, and the water storage tank is connected to the spray device. The control module controls the air pressure control device to continue to deliver gas into the water storage tank, and the water in the water storage tank flows into the spray device under the action of pressure difference.
[0077] In some embodiments, the pneumatic control device 30 includes an air pump 31 and a ventilation assembly. The air pump 31 includes an air inlet 311 and an air outlet 312. The ventilation assembly includes a ventilation valve 32 and a drive device 33. The ventilation valve 32 includes an air inlet 3211, an air outlet 3212, a first guide port 3221, and a second guide port 3222. The air outlet 3212 is connected to the air inlet 311, and the air inlet 3211 is connected to the air outlet 312. The first guide port 3221 is connected to the water storage tank 20, and the second guide port 3222 is connected to the outside or external components. The ventilation valve 32 has a first state and a second state. When the ventilation valve 32 is in the first state, the air outlet 3212 is connected to the first guide port 3221, and the air inlet 3211 is connected to the second guide port 3222. When the ventilation valve 32 is in the second state, the air outlet 3212 is connected to the second guide port 3222, and the air inlet 3211 is connected to the first guide port 3221. The driving device 33 is used to drive the ventilation valve 32 to switch between the first state and the second state. The steps of the control module controlling the air pressure control device to deliver gas into the water storage tank include: the control module controlling the drive device to drive the air exchange valve to the second state, and controlling the air pump to be in the open state.
