[0048] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0049] like Figure 1-Figure 6 As shown, an embodiment of the present application provides an air treatment device, including a housing 1 , a humidification module 10 and a first damper assembly 2 .

[0050] The housing 1 has an air duct, which includes an air inlet chamber 11 , a humidification chamber 12 and an air outlet 13 , and along the air flow direction in the air duct, the humidification chamber 12 is located downstream of the air inlet chamber 11 .

[0051] The humidification module 10 is arranged in the humidification chamber 12, and divides the humidification chamber 12 into a first cavity 121 and a second cavity 122. The first cavity 121 is connected to the air inlet cavity 11, and the second cavity 122 is connected to the air outlet 13. The humidification module 10 is configured to allow air to pass through from the first cavity 121 to enter the second cavity 122.

[0052] The first damper assembly 2 is disposed between the air inlet cavity 11 and the second cavity 122 , and controls the connection and disconnection between the air inlet cavity 11 and the second cavity 122 .

[0053] The air treatment device of the embodiment of the present application has an air duct of a box body 1 including an air inlet chamber 11, a humidification chamber 12 and an air outlet 13, and the humidification chamber 12 is divided into a first cavity 121 and a second cavity 122 by a humidification module 10, and both the first cavity 121 and the second cavity 122 can be communicated with the air inlet chamber 11, and a first damper assembly 2 is provided to control the connection between the air inlet chamber 11 and the second cavity 122, and the second cavity 122 can also be communicated with the air outlet 13.

[0054] When the air treatment device processes the air and does not need to humidify the air, the first damper assembly 2 can be opened. At this time, the air inlet chamber 11 is connected to the second chamber 122. After the air enters the air inlet chamber 11, it can enter the second chamber 122 of the humidification chamber 12 from the first damper assembly 2 and be discharged from the air outlet 13 (the flow direction of the air is as shown in FIG. Figure 4 When the air treatment device processes the air and needs to humidify the air, the first damper assembly 2 can be closed, and the air inlet chamber 11 is now separated from the second chamber 122. After the air enters the air inlet chamber 11, it can only enter the first chamber 121 of the humidification chamber 12, and then pass through the humidification module 10 to realize the humidification function, and then enter the second chamber 122 of the humidification chamber 12, and be discharged from the air outlet 13.

[0055] In the air treatment device, the humidification chamber 12 is divided into a first cavity 121 and a second cavity 122 by the humidification module 10, and the connection or isolation between the air inlet cavity 11 and the second cavity 122 is controlled by the first damper assembly 2 to realize the humidification or non-humidification function of the air, and when not humidified, the air does not need to flow through the humidification module 10, so that the flow resistance of the air is small, avoiding problems such as small air volume caused by large wind resistance.

[0056] In some exemplary embodiments, Figure 3-Figure 5 As shown, a partition 3 is provided in the air duct, and the partition 3 separates the air inlet chamber 11 and the humidification chamber 12. The partition 3 is provided with a first connecting hole 31 connecting the first cavity 121 and the air inlet chamber 11. The partition 3 is also provided with a second connecting hole 32 connecting the second cavity 122 and the air inlet chamber 11. The first damper assembly 2 is installed at the second connecting hole 32 and is configured to open or close the second connecting hole 32.

[0057] A partition 3 is provided in the air duct, and the partition 3 may be a partition plate, and the partition plate may be arranged horizontally to separate the air inlet chamber 11 and the humidification chamber 12, wherein the air inlet chamber 11 may be located at the lower side of the partition plate, and the humidification chamber 12 may be located at the upper side of the partition plate, so that the humidification chamber 12 is located at the upper side of the air inlet chamber 11. The humidification module 10 may be supported on the partition 3. A first connecting hole 31 is provided on the partition 3 to connect the first cavity 121 of the humidification chamber 12 and the air inlet chamber 11, and a second connecting hole 32 is provided on the partition 3 to connect the second cavity 122 of the humidification chamber 12 and the air inlet chamber 11. The first damper assembly 2 is installed at the second connecting hole 32, and the second connecting hole 32 may be opened or closed to realize the connection or isolation between the air inlet chamber 11 and the second cavity 122.

[0058] In some exemplary embodiments, Figure 3-Figure 5 As shown, the humidification module 10 is U-shaped, the open end of the humidification module 10 abuts against the cavity wall of the humidification cavity 12 , one of the first cavity 121 and the second cavity 122 is located outside the humidification module 10 , and the other is located inside the humidification module 10 .

[0059] The opening end of the U-shaped humidification module 10 may face the front side and may abut against the cavity wall of the front side of the humidification chamber 12. At this time, the humidification module 10 and the cavity wall of the front side of the humidification chamber 12 may cooperate to form a second cavity 122, which may be located inside the humidification module 10; the interval between the humidification module 10 and the cavity wall of the humidification chamber 12 may form a U-shaped first cavity 121, which may be located outside the humidification module 10. When humidifying the air, the air in the air inlet cavity 11 may first enter the first cavity 121, then pass through the humidification module 10 from the left, right, and rear sides, and then enter the second cavity 122 in the humidification module 10, and finally be discharged from the air outlet 13.

[0060] Of course, the first cavity 121 of the humidification chamber 12 may also be located on the inner side of the U-shaped humidification module 10 , and the second cavity 122 may also be located on the outer side of the U-shaped humidification module 10 .

[0061] Of course, the humidification module 10 is not limited to the U-shape, but can also be other shapes, such as: the humidification module 10 can be linear or L-shaped, both ends of the humidification module 10 are in contact with the cavity wall of the humidification chamber 12, and the first cavity 121 and the second cavity 122 can be respectively located on both sides of the humidification module 10; or, the humidification module 10 can be annular, one of the first cavity 121 and the second cavity 122 can be located outside the humidification module 10, and the other can be located inside the humidification module 10, such as: the space inside the humidification module 10 can form the second cavity 122, and the annular interval between the humidification module 10 and the cavity wall of the humidification chamber 12 can form the first cavity 121, and the first cavity 121 can be located outside the humidification module 10.

[0062] In some exemplary embodiments, Figure 3-Figure 5 As shown, the first damper assembly 2 includes at least one first damper 21, and the at least one first damper 21 is configured to be movable to open or close the second communication hole 32. The first damper assembly 2 may also include a driving device, which may include a motor, etc. The driving device may drive the at least one first damper 21 to move to open or close the second communication hole 32, thereby achieving the connection or isolation between the air inlet cavity 11 and the second cavity 122.

[0063] In some exemplary embodiments, Figure 3-Figure 5 As shown, the first damper assembly 2 includes two first dampers 21, and the two first dampers 21 are rotatably installed at the second communication hole 32; the two first dampers 21 are configured to be able to rotate to expand to close the second communication hole 32, and the two first dampers 21 are configured to be able to rotate to close to open the second communication hole 32 (as shown in FIG. Figure 3-Figure 5 shown).

[0064] In the first damper assembly 2, the two first dampers 21 are rotatably mounted at the second connecting hole 32. When the driving device drives the two first dampers 21 to rotate to the unfolded state, the two second dampers can cooperate to close the second connecting hole 32, thereby separating the air inlet cavity 11 from the second cavity 122; when the driving device drives the two first dampers 21 to rotate to the retracted state, the first damper assembly 2 can open the second connecting hole 32, thereby connecting the air inlet cavity 11 to the second cavity 122.

[0065] In some exemplary embodiments, Figure 3-Figure 5 As shown, the end surfaces of the two first dampers 21 in the folded state are in contact with each other and are parallel to the air flow direction at the second ventilation hole.

[0066] When the two first dampers 21 are in a retracted state, that is, when the second connecting hole 32 is closed and the air inlet chamber 11 is connected to the second cavity 122, the end faces of the two first dampers 21 fit together, and the end faces of the two first dampers 21 are roughly parallel to the flow direction of the airflow at the second connecting hole 32, so as to minimize the wind resistance caused by the first damper assembly 2.

[0067] In some exemplary embodiments, Figure 3-Figure 5 As shown, one end of the two first dampers 21 can be rotatably mounted at the second connecting hole 32 , and the other end of the two first dampers 21 in the retracted state is arranged to be located in the second cavity 122 .

[0068] One end of the two first air doors 21 can be rotatably installed at the second connecting hole 32. When the two first air doors 21 are in the expanded state, the edges of the two first air doors 21 can abut against the inner wall of the second connecting hole 32 to open the second connecting hole 32 and realize the connection between the air inlet chamber 11 and the second cavity 122; when the two first air doors 21 are switched from the expanded state to the retracted state, the other ends of the two first air doors 21 can be rotated toward the second cavity 122 of the humidification chamber 12, so that the other ends of the two first air doors 21 in the retracted state are located in the second cavity 122, so that the rotation of the first air doors 21 does not affect the installation of the components in the air inlet chamber 11 (such as the heating module 7, purification module 8, etc. described below), and the first air doors 21 will not interfere with the components in the air inlet chamber 11.

[0069] In some exemplary embodiments, Figure 3 As shown, a ventilation grille is provided at the first connecting hole 31 .

[0070] When the humidification function is not needed, the first damper assembly 2 is opened. Since the air resistance at the second connecting hole 32 is less than the air resistance at the first connecting hole 31 provided with the ventilation grille, after the air enters the air inlet chamber 11, it preferentially enters the second cavity 122 of the humidification chamber 12 from the second connecting hole 32, and is finally discharged from the air outlet 13. Since the air resistance at the second connecting hole 32 is small, less air passes through the ventilation grille in the first connecting hole 31 and then enters the first cavity 121 of the humidification chamber 12, and then passes through the humidification module 10 to enter the second cavity 122 of the humidification chamber 12.

[0071] When the humidification function needs to be turned on, the first damper assembly 2 is closed. Therefore, after the air enters the air inlet chamber 11, it can only enter the first cavity 121 of the humidification chamber 12 from the first connecting hole 31 provided with the ventilation grille. All the air then passes through the humidification module 10 to realize the humidification function and then enters the second cavity 122 of the humidification chamber 12, and is finally discharged from the air outlet 13.

[0072] Of course, the first connecting hole 31 may not be provided with a ventilation grille, but other methods may be used to control whether the air passes through the first connecting hole 31. For example, a second damper assembly may be provided at the first connecting hole 31, and the second damper assembly is configured to open or close the first connecting hole 31. The second damper assembly can control the opening and closing of the first connecting hole 31, and further control the air in the air inlet chamber 11 to enter the first cavity 121 or the second cavity 122 of the humidification chamber 12.

[0073] In some exemplary embodiments, Figure 5-Figure 6As shown, the air treatment device also includes a first water tank 4, which is located above the humidification module 10 (such as a wet film). The first water tank 4 has a first water inlet and a water outlet 41. The water outlet 41 is arranged on the bottom wall of the first water tank 4, and the water outlet 41 is located above the humidification module 10 so that the water in the first water tank 4 can drip onto the humidification module 10.

[0074] A first water tank 4 is provided above the humidification module 10, and water can be added to the first water tank 4 through a first water inlet; a drain port 41 is provided on the bottom wall of the first water tank 4, and the drain port 41 is located above the humidification module 10, so that the water in the first water tank 4 can drip onto the humidification module 10 through the drain port 41, supplying water to the humidification module 10, so that the humidification module 10 humidifies the air.

[0075] In some exemplary embodiments, Figure 5-Figure 6 As shown, the inner bottom surface of the first water tank 4 is provided with a separation rib 42, and there is a gap between the separation rib 42 and the inner top surface of the first water tank 4. The two sides of the separation rib 42 are respectively a water inlet area 43 and a water outlet area 44, the water outlet 41 is connected to the water outlet area 44, and the first water inlet is connected to the water inlet area 43. Among them, the shapes of the first water tank 4 and the water outlet 41 are both adapted to the shape of the humidification module 10, and are both U-shaped (or linear, L-shaped, annular, etc.).

[0076] The inner bottom surface of the first water tank 4 (the inner wall surface of the bottom wall of the first water tank 4) is provided with a separation rib 42, and there is a gap between the separation rib 42 and the inner top surface of the first water tank 4 (the inner wall surface of the top wall of the first water tank 4), and the separation rib 42 can separate the space in the first water tank 4 into a water inlet area 43 and a water outlet area 44, wherein the first water inlet and the water outlet 41 are respectively connected to the water inlet area 43 and the water outlet 44. Water enters the water inlet area 43 of the first water tank 4 from the first water inlet, and when the liquid level of the water inlet area 43 exceeds the separation rib 42, the water in the water inlet area 43 also flows through the separation rib 42 into the water outlet 44, and then drips from the water outlet 41 onto the humidification module 10.

[0077] By setting the separating rib 42, the liquid level in the water inlet area 43 is higher than the separating rib 42 before overflowing from the separating rib 42 to the water outlet area 44, and then flowing out from the water outlet 41, so that the water flow can be discharged from various places of the U-shaped water outlet 41 and drip onto the U-shaped humidification module 10, and the water flow at various places of the water outlet 41 is uniform, and the humidification degree of the humidification module 10 is more balanced and consistent, which is conducive to ensuring the consistent humidification effect of the air. If the separating rib 42 is not set, the water in the first water tank 4 will preferentially flow out from the part of the water outlet 41 close to the first water inlet, resulting in uneven water flow at various places of the water outlet 41, thereby affecting the humidification effect.

[0078] In some exemplary embodiments, Figure 5-Figure 6As shown, the air treatment device further includes a water receiving tray 5 , which is located below the humidification module 10 and is configured to receive water dripping from the humidification module 10 .

[0079] The shapes of the water receiving tray 5 and the humidification module 10 are adapted to each other and are both U-shaped (or straight, L-shaped, annular, etc.) to prevent the water receiving tray 5 from affecting the air in the air inlet chamber 11 from entering the first cavity 121 or the second cavity 122 of the humidification chamber 12.

[0080] In some exemplary embodiments, the first water tank 4, the water receiving tray 5, the water outlet 41 and the humidification module 10 are adapted to each other in shape and are all U-shaped, linear, L-shaped or ring-shaped.

[0081] In some exemplary embodiments, Figure 5-Figure 6 As shown, the air treatment device also includes a second water tank 61 and a water pump 62. The water receiving tray 5 is provided with a drain port 51, and the drain port 51 and the first water inlet are both connected to the second water tank 61; the water pump 62 is arranged in the water path connecting the second water tank 61 and the first water inlet.

[0082] The second water tank 61 can be arranged at the lower side of the air inlet chamber 11, and the second water tank 61 can be connected to the first water inlet of the first water tank 4 through a water supply pipe 63, and a water pump 62 is provided on the water supply pipe 63, so that water can be supplied from the second water tank 61 to the first water tank 4 through the water pump 62. The second water tank 61 is also connected to the drain port 51 of the water receiving tray 5, so that the accumulated water in the water receiving tray 5 can flow into the second water tank 61, so that a circulating water path is formed between the first water tank 4, the water receiving tray 5, and the second water tank 61.

[0083] In some exemplary embodiments, Figure 1-Figure 2 As shown, the air treatment device further includes a water supply box 64 , which is located outside the box body 1 , and a water outlet of the water supply box 64 is connected to the second water inlet of the second water tank 61 .

[0084] The water supply tank 64 may be located outside the housing 1 and disposed on the front side of the housing 1, and a recess is provided on the front side of the housing 1 to form an installation cavity 18 for installing the water supply tank 64. A water outlet may be provided at the lower portion of the water supply tank 64, and the water outlet may be communicated with the second water inlet of the second water tank 61, so as to supply water to the second water tank 61 through the water supply tank 64, thereby indirectly supplying water to the humidification module 10.

[0085] In some exemplary embodiments, the water supply tank 64 may be a movable external water supply tank, and the water supply tank 64 and the second water tank 61 are connected by a water valve. The water supply tank 64 may be sealed, and a water valve is installed at the water outlet at the bottom. The water valve has structures such as a spring and an air valve. When the water supply tank 64 is connected to the second water tank 61, the boss at the second water inlet of the second water tank 61 can push open the air valve, so that the water in the water supply tank 64 will flow to the second water tank 61. When the water in the second water tank 61 is submerged above the lowest point of the water valve, the water in the water supply tank 64 will no longer be injected into the second water tank 61 because air cannot enter the water supply tank 64, until the water level in the second water tank 61 is lower than the lowest point of the water valve after use. When the water supply tank 64 is removed (for maintenance or water addition), the air valve presses against the water outlet of the water supply tank 64 under the action of the spring to prevent water leakage.

[0086] In some exemplary embodiments, Figure 3-Figure 5 As shown, the air treatment device further includes a heating module 7 , and the heating module 7 is disposed in the air inlet cavity 11 .

[0087] The heating module 7 is arranged in the air inlet chamber 11, and the air inlet chamber 11 is located upstream of the humidification chamber 12, so that the heating module 7 is located upstream of the humidification module 10. When the heating and humidification functions are turned on at the same time, the air entering the air inlet chamber 11 can be heated by the heating module 7, and the air is first heated by the heating device to form hot air, and the hot air then passes through the humidification module 10. Since the water content of the saturated air of the hot air increases, it can carry more water vapor on the water module, and finally blown through the air outlet 13, so that the humidification amount of the air is further increased, and the humidification effect of the air is improved.

[0088] In some exemplary embodiments, Figure 3-Figure 5 As shown, the air treatment device also includes a purification module 8, which is arranged in the air inlet chamber 11, and the purification module 8 can be located on a side of the heating module 7 close to the humidification chamber 12, such as: the purification module 8 can be located on the upper side of the heating module 7.

[0089] The purification module 8 and the heating module 7 are both arranged in the air inlet chamber 11, and the purification module 8 is located on the side of the heating module 7 close to the humidification chamber 12, so that the hot air heated by the heating module 7 can enter the first cavity 121 or the second cavity 122 of the humidification chamber 12 after flowing through the purification module 8. The hot air can have a disinfecting and cleaning effect on the purification module 8.

[0090] In some exemplary embodiments, Figure 1 , Figure 3-Figure 5As shown, the air duct also includes an outdoor fresh air inlet 14 and an indoor return air inlet 15, and both the outdoor fresh air inlet 14 and the indoor return air inlet 15 are connected to the air inlet chamber 11. Among them. Two indoor return air inlets 15 can be provided, and the two indoor return air inlets 15 can be respectively provided on the left and right sides of the box body 1, and the indoor air can enter the air inlet chamber 11 through the indoor return air inlet 15. A third damper assembly 16 can be provided at the indoor return air inlet 15 to control the opening and closing of the indoor return air inlet 15. The outdoor fresh air inlet 14 can be provided on the rear side of the box body 1, and the outdoor fresh air can enter the air inlet chamber 11 through the outdoor fresh air inlet 14.

[0091] In some exemplary embodiments, Figure 1-Figure 5 As shown, the air duct also includes an air outlet cavity 17, and the second cavity 122 of the humidification cavity 12 can be connected with the air outlet 13 through the air outlet cavity 17. The air outlet cavity 17 can be arranged on the upper side of the humidification cavity 12, and a fan 9 can be arranged in the air outlet cavity. When the fan 9 is working, it can drive the air to flow in the air duct.

[0092] like Figure 1-Figure 6 As shown, the embodiment of the present application provides an air treatment device with fresh air, air humidification, purification and heating functions. The air treatment device comprises a fan 9, a box 1, a heating module 7, a purification module 8, a humidification module 10, a first water tank 4, a second water tank 61, a water supply tank 64, etc. The fan 9 is placed in the air outlet cavity 17 at the top of the box 1, and indoor return air inlets 15 are provided on the left and right sides of the box 1, and a third damper assembly 16 is provided at the indoor return air inlet 15. A heating module 7 is installed in the middle and lower part of the box 1, and a horizontal purification module 8 and a vertical humidification module 10 are provided in the middle of the box 1. A detachable water supply tank 64 is arranged on the front side of the box 1, and an outdoor fresh air inlet 14 is provided on the rear side of the box 1, and the outdoor fresh air enters from the outdoor fresh air inlet 14.

[0093] A partition 3 is also provided in the middle of the housing 1, and an air inlet chamber 11 and a humidification chamber 12 are formed on the upper and lower sides of the partition 3, respectively. The humidification module 10 in the humidification chamber 12 is supported by the partition 3, and a first cavity 121 and a second cavity 122 are formed on the inner and outer sides of the humidification module 10, respectively. A ventilation grille is provided at the first connecting hole 31 where the air inlet chamber 11 and the first cavity 121 of the humidification chamber 12 are connected, and a sealed first damper assembly 2 is provided at the second connecting hole 32 where the air inlet chamber 11 and the second cavity 122 of the humidification chamber 12 are connected. The first damper assembly 2 can control the flow direction of the air in the air inlet chamber 11.

[0094] When the air handling device is working, the fan is turned on. In the fresh air mode, outdoor fresh air can enter the air inlet chamber 11 through the outdoor fresh air inlet 14; in the indoor circulation mode, indoor air can enter the air inlet chamber 11 from the indoor return air inlet 15.

[0095] When the air handling device does not need to start humidification, the first damper assembly 2 is opened. Since the air resistance at the second connecting hole 32 is small, the air passes through the purification module 8 and preferentially enters the second cavity 122 of the humidification cavity 12 from the second connecting hole 32, then enters the air outlet cavity provided with the fan, and is discharged from the upper air outlet 13 (the air flow direction is as follows). Figure 4 As the air resistance at the second connecting hole 32 is smaller than the air resistance at the first connecting hole 31 provided with the ventilation grille, less air passes through the first connecting hole 31 and the humidification module 10 and then enters the air outlet cavity.

[0096] When the air treatment device needs humidification, the first damper assembly 2 is closed, and all the air after passing through the purification module 8 can only enter the first cavity 121 of the humidification chamber 12 from the first connecting hole 31 provided with the ventilation grille. The air passes through the humidification module 10 to realize the humidification function, that is, the humidification has an independent air channel.

[0097] When the heating and humidification functions are turned on at the same time, the air entering from the outdoor fresh air inlet 14 or the air entering the air inlet chamber 11 from the indoor return air inlet 15 can be heated. The air is first heated by the heating device, then purified by the purification module 8, and the hot air then passes through the humidification module 10. The water content of the hot air saturated air increases, and it can carry more water vapor on the wet film into the air outlet chamber, and finally blow into the room through the air outlet 13, so that the indoor humidification amount is further increased. The hot air can also have a disinfecting and cleaning effect on the purification module 8.

[0098] Therefore, in both the fresh air mode and the indoor circulation mode, the air treatment device may have one or more of the purification, humidification and heating functions.

[0099] Furthermore, two water tanks are arranged in the box body 1: a first water tank 4 and a second water tank 61. The second water tank 61 at the lower side can take water from a movable water supply tank 64 through a water valve. A water pump 62 is installed at the rear side of the second water tank 61. The water pump 62 transfers the water in the second water tank 61 to the first water tank 4 at the upper side through a water supply pipe 63. The first water tank 4 is directly above the humidification module 10, and a water outlet 41 is opened on the bottom wall of the first water tank 4 along the shape of the humidification module 10. Water flows out from the water outlet 41 and pours on the humidification module 10, which greatly increases the water content of the humidification module 10, and also greatly increases the moisture that the air passing through the humidification module 10 can carry. A water receiving tray 5 is provided directly below the humidification module 10. Water flows from the first water tank 4 through the humidification module 10 and is stored in the water receiving tray 5. A drain port 51 is opened on the rear side of the water receiving tray 5. The water in the water receiving tray 5 will flow back to the second water tank 61 through the drain port 51 to realize water circulation.

[0100] Furthermore, a partition rib 42 is provided on the inner bottom surface of the first water tank 4, and the first water inlet and the drain port 41 of the first water tank 4 are respectively connected with the water inlet area 43 and the drain port 44 on both sides of the partition rib 42, so that after water enters the first water tank 4 from the first water inlet, the liquid level of the water stored in the water inlet area 43 is higher than the partition rib 42, and the water in the water inlet area 43 can overflow from the partition rib 42 to the drain port 44, and then flow out from the drain port 41. The purpose of setting the partition rib 42 is to allow the water flow to be uniformly discharged from all parts of the drain port 41, so that the water flow out of the drain port 41 is uniform, so as to avoid that when the partition rib 42 is not provided, the water will preferentially flow out from the part of the drain port 41 close to the first water inlet, resulting in uneven water flow at all parts of the drain port 41, resulting in uneven water content at all parts of the humidification module 10 and uneven humidification of the air.

[0101] Furthermore, the movable water supply tank 64 and the second water tank 61 are connected by a water valve. The water supply tank 64 is sealed, and a water valve is installed at the bottom. The water valve has a spring and an air valve. When the water supply tank 64 is connected to the second water tank 61, the boss near the second water inlet of the second water tank 61 pushes the air valve open, and water flows from the water supply tank 64 to the second water tank 61. When the water in the second water tank 61 is submerged above the lowest point of the water valve, the water in the water supply tank 64 is no longer injected into the second water tank 61 because air cannot enter the water supply tank 64, until the water in the second water tank 61 is lower than the lowest point of the water valve after use. When the water supply tank 64 is removed, the air valve presses against the water outlet of the water supply tank 64 under the action of the spring to prevent water leakage.
