[0002] Humidification solutions in related technologies all employ a wet-film immersion method, designing a water tank to soak the wet film, allowing water to permeate and then ventilate. However, the humidification capacity of the wet film in the above solutions is limited. When the wet film area is large, the water in the tank cannot fully saturate the entire film, thus limiting the humidification capacity. Furthermore, if the humidifying water is not cleaned and stored in the tank for a long time, it can cause bacterial growth, which may actually harm health. Summary of the Invention

[0047] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0048] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0049] The air handling equipment 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings. The air handling equipment 100 uses circulating water to wet the wet membrane 41. On the one hand, it can achieve overall wetting of the wet membrane 41 through bottom-drip wetting, thereby maximizing the humidification capacity of the wet membrane 41. On the other hand, it can also reduce the growth of bacteria in the water-containing cavity 21 to a certain extent, thereby improving the hygiene level.

[0050] An air handling device 100 according to an embodiment of the present invention includes: a housing 1, a water tank assembly 2, a fan 3, a wet film assembly 4, a water receiving tank 5, and a water pump 6.

[0051] Specifically, refer to Figure 1 An air inlet 11 and an air outlet 12 are formed on the housing 1. For example, combined with Figure 11 The housing 1 may include a base 13, a panel 14 disposed on the base 13, a rear shell 15 disposed behind the panel 14, the rear shell 15 being disposed on the base 13, and a top cover 16 covering the top of the panel 14 and the rear shell 15. The top cover 16 and the base 13 are disposed opposite each other in the height direction. The cross-section of the panel 14 may be U-shaped. (The last sentence appears to be incomplete and possibly refers to a different housing.) Figure 2 and Figure 3 Air inlets 11 can be formed on both sides of panel 14, and air outlets 12 are formed on top cover 16, which can at least partially be formed as a grille structure. Air can enter the air handling unit 100 through air inlets 11, and the air humidified by the air handling unit 100 can be discharged through air outlets 12.

[0052] The water tank assembly 2 is located on the base 13 of the housing 1 and includes a water-containing cavity 21. For example, see reference... Figure 4 The water tank assembly 2 can be mounted on the base 13, and the water tank assembly 2 can include a water-containing cavity 21, which can hold a certain amount of water for humidification.

[0053] The fan 3 is connected to the base 13; the wet film assembly 4 is located at least one of the air inlet side and air outlet side of the fan 3 and includes a wet film 41. A water storage tank 42 communicating with the water storage cavity 21 is formed on the top of the wet film assembly 4, and a spray hole is formed at the position of the water storage tank 42 corresponding to the wet film 41.

[0054] For example, the fan 3 can be mounted on the base 13; the fan 3 can be, for example, a centrifugal fan. In some embodiments, the wet film assembly 4 may be provided only on the air inlet side of the fan 3; in some embodiments, the wet film assembly 4 may be provided only on the air outlet side of the fan 3; in some embodiments, the wet film assembly 4 may be provided not only on the air inlet side of the fan 3, but also on the air outlet side of the fan 3.

[0055] Among them, combined Figure 7 The wet membrane assembly 4 may include a wet membrane 41, which extends along the height of the air handling unit 100. A water storage tank 42 may be formed on the top of the wet membrane assembly 4, and the water storage tank 42 is connected to the water holding chamber 21. Spray holes are formed on the bottom wall of the water storage tank 42, and the spray holes and the wet membrane 41 may be correspondingly arranged in the vertical direction. In this way, the water injected into the water storage tank 42 can be sprayed down through the spray holes to wet the wet membrane 41, achieving overall wetting of the wet membrane 41 and maximizing the humidification capacity of the wet membrane 41. This solves the technical problem in related technologies that the wet membrane 41 cannot be fully wetted and the humidification capacity cannot be fully utilized.

[0056] The water collection tank 5 is located at the bottom of the wet membrane assembly 4 and communicates with the water storage chamber 21. For example, in the height direction of the air handling unit 100, the water collection tank 5 is located at the bottom of the wet membrane assembly 4 and communicates with the water storage chamber 21. In this way, excess water after wetting the wet membrane 41 can be collected by the water collection tank 5 and can be further returned to the water storage chamber 21 to participate in the humidification cycle.

[0057] A water pump 6 is mounted on the base 13 to deliver water from the water-containing chamber 21 to the water storage tank 42. For example, the water pump 6 can be a suction pump, and it can be mounted on the base 13. In this way, the water pump 6 can deliver water from the water-containing chamber 21 to the water storage tank 42, and then the wet membrane 41 is wetted by spraying through the spray holes on the water storage tank 42, so as to achieve overall wetting of the wet membrane 41 and maximize the humidification capacity of the wet membrane 41.

[0058] Among them, reference Figure 6 and Figure 7 The arrows in the figure indicate the direction of water flow. The water circulation process of the air handling equipment 100 according to the embodiment of the present invention may include: the water pump 6 can send the water in the water chamber 21 to the water storage tank 42. The water entering the water storage tank 42 can wet the wet membrane 41 through the spray hole. The excess water that wets the wet membrane 41 can flow into the water receiving tank 5. Since the water receiving tank is connected to the water chamber 21, the water that flows into the water receiving tank 5 after wetting the wet membrane 41 can flow back into the water chamber 21 and further participate in the humidification cycle.

[0059] According to an embodiment of the air handling equipment 100 of the present invention, circulating water is used to wet the wet membrane 41. Specifically, the water pump 6 can send water from the water-containing chamber 21 to the water storage tank 42. The water entering the water storage tank 42 can be sprayed out through the spray holes to wet the wet membrane 41, for example, the wet membrane 41 can be wetted from top to bottom, so that the wet membrane 41 is fully wetted, maximizing the humidification capacity of the wet membrane 41. Excess water used to wet the wet membrane 41 can flow into the water receiving tank 5. Since the water receiving tank 5 is connected to the water-containing chamber 21, the water that flows into the water receiving tank 5 after wetting the wet membrane 41 can flow back into the water-containing chamber 21 to further participate in the humidification cycle. In this way, by using circulating water to wet the wet membrane 41, on the one hand, the wet membrane 41 can be wetted from top to bottom, maximizing the humidification capacity of the wet membrane 41; on the other hand, using circulating water for humidification also helps to reduce the growth of bacteria in the water-containing cavity 21, improving the hygiene level. This can solve the technical problems of insufficient wetting of the wet membrane 41 and low hygiene level in related technologies.

[0060] According to the air handling equipment 100 of the present invention, circulating water is used to wet the wet membrane 41. On the one hand, the wet membrane 41 can be wetted as a whole by the downward wet membrane 41, so as to maximize the humidification capacity of the wet membrane 41. On the other hand, it can also reduce the growth of bacteria in the water chamber 21 to a certain extent, thereby improving the hygiene level.

[0061] In some embodiments of the present invention, the bottom of the water receiving tank 5 is provided with a drain pipe 51 communicating with the water holding cavity 21. For example, see reference to Figure 7 and Figure 12The bottom of the water tank 5 can also be provided with a drain pipe 51, which is connected to the water chamber 21. The drain pipe 51 is sealed to the water chamber 21, so that the water in the water tank 5 can flow back to the water chamber 21 through the drain pipe 51 to further participate in the humidification cycle, and can also prevent water leakage, thus ensuring good reliability.

[0062] For example, in the height direction of the air handling unit 100, the water receiving tank 5 is located at the bottom of the wet film assembly 4. In some embodiments, the bottom of the wet film assembly 4 is located within the water receiving tank 5, so that excess water during the wetting of the wet film 41 can be collected through the water receiving tank 5. The water receiving tank 5 can be located at the top of the water tank assembly 2. Furthermore, the top of the water tank assembly 2 can be formed with a positioning groove for positioning the water receiving tank 5, through which the positioning groove can be used to position the water receiving tank 5 on the water tank assembly 2.

[0063] The above describes an embodiment in which the bottom of the water receiving tank 5 is provided with a drain pipe 51. Of course, in some embodiments of the present invention, the water receiving tank 5 may also be connected to the water holding cavity 21 by means of an external pipeline. The present invention does not specifically limit this.

[0064] The water circulation process of the air handling equipment 100 according to an embodiment of the present invention may further include: the water pump 6 can send the water pump 6 in the water holding chamber 21 to the water storage tank 42, the water entering the water storage tank 42 can wet the wet membrane 41 through the spray hole, and the excess water wetted by the wet membrane 41 can flow into the water receiving tank 5. Since the water receiving tank 5 is connected to the water holding chamber 21 through the drain pipe 51, the water that flows into the water receiving tank 5 after wetting the wet membrane 41 can be further returned to the water holding chamber 21 through the drain pipe 51 to participate in the humidification cycle.

[0065] According to an embodiment of the air handling equipment 100 of the present invention, circulating water is used to wet the wet membrane 41. Specifically, the water pump 6 can send water from the water-containing chamber 21 to the water storage tank 42. The water entering the water storage tank 42 can be sprayed out through the spray holes to wet the wet membrane 41, for example, the wet membrane 41 can be wetted from top to bottom, so that the wet membrane 41 is fully wetted, maximizing the humidification capacity of the wet membrane 41. Excess water used to wet the wet membrane 41 can flow into the water receiving tank 5. Since the water receiving tank 5 is connected to the water-containing chamber 21 through the drain pipe 51, the water that flows into the water receiving tank 5 after wetting the wet membrane 41 can be further returned to the water-containing chamber 21 through the drain pipe 51 to participate in the humidification cycle. In this way, by using circulating water to wet the wet membrane 41, on the one hand, the wet membrane 41 can be wetted from top to bottom, maximizing the humidification capacity of the wet membrane 41; on the other hand, using circulating water for humidification also helps to reduce the growth of bacteria in the water-containing cavity 21, ensuring the cleanliness of the water circulation and improving the hygiene level. This can better solve the technical problems of insufficient wetting of the wet membrane 41 and low hygiene level in related technologies.

[0066] In some embodiments of the present invention, the inner bottom surface of the water receiving tank 5 is formed as a plane, and the drain pipe 51 can be provided at the bottom of the water receiving tank 5. In this way, the water in the water receiving tank 5 can be easily returned to the water holding chamber 21 through the drain pipe 51 to participate in the humidification cycle.

[0067] Of course, the present invention is not limited to this. In some embodiments, the inner bottom surface of the water receiving tank 5 can also be formed as an inclined surface, and the drain pipe 51 can be located at the lowest point of the inclined surface. By placing the drain pipe 51 at the lowest point of the inclined surface, it is not only convenient to drain the water in the water receiving tank 5 into the water holding cavity 21 through the drain pipe 51, but also beneficial to drain the water in the water receiving tank 5 completely.

[0068] In addition, in some embodiments of the present invention, the bottom wall of the water tank 5 may extend downward at an angle, and the drain pipe 51 may be located at the lowest point of the bottom wall.

[0069] According to some embodiments of the present invention, the drain pipe 51 is located at a position on the water receiving tank 5 corresponding to the air inlet side and / or the air outlet side. For example, when the wet film assembly 4 is only provided on the air inlet side of the fan 3, the drain pipe 51 may be provided only at a position on the water receiving tank 5 corresponding to the air inlet side. When the wet film assembly 4 is only provided on the air outlet side of the fan 3, the drain pipe 51 may be provided only at a position on the water receiving tank 5 corresponding to the air outlet side. When the wet film assembly 4 is provided on both the air inlet and air outlet sides of the fan 3, the drain pipe 51 may be provided only at a position on the water receiving tank 5 corresponding to the air inlet side, or only at a position on the water receiving tank 5 corresponding to the air outlet side, or both at positions on the water receiving tank 5 corresponding to the air inlet side and the air outlet side. The specific location of the drain pipe 51 can be adapted according to actual needs.

[0070] For example, the bottom wall of the water storage tank 42 can be formed with multiple spray holes, which can be arranged at intervals on the bottom wall of the water storage tank 42, including uniform intervals and non-uniform intervals.

[0071] In some optional embodiments of the present invention, the spray holes can be evenly spaced on the bottom wall of the water storage tank 42. By evenly spaced the multiple spray holes on the bottom wall of the water storage tank 42, it is beneficial to ensure the uniformity of water output, thereby ensuring the uniformity of humidification of the wet film 41, and also facilitating the full wetting of the wet film 41.

[0072] In some embodiments of the present invention, the spray holes may be formed as through holes, stepped holes, or conical holes, etc., and the spray holes may be formed as regular shapes (such as circles, triangles, squares, etc.) or irregular shapes, etc., and the present invention does not limit them.

[0073] Reference Figure 4 and Figure 14 In some embodiments of the present invention, the wet film assembly 4 includes a support 43 and a fixing frame 44. Specifically, the support 43 is provided with a first water pump connector 431, one end of which can be connected to a water pump 6 via a water inlet pipe, and the other end of which can be connected to a water storage tank 42. The fixing frame 44 is connected to the support 43 and can be embedded in the support 43 by means of a snap fastener, etc. The wet film 41 is adapted to be fixed by the fixing frame 44, and the wet film 41 can be embedded in the fixing frame 44. The water storage tank 42 is formed on the top of the fixing frame 44, and the wet film 41 and the water storage tank 42 are directly opposite each other in the vertical direction, such as the water storage tank 42 and the wet film 41 can be directly opposite each other in the height direction of the air handling equipment 100. In this way, the water pump 6 can send water from the water chamber 21 to the water storage tank 42 through the first water pump connector 431, and then spray it out through the spray hole to achieve full wetting of the wet film 41.

[0074] The water circulation process of the air handling equipment 100 according to an embodiment of the present invention may further include: the water pump 6 can pump the water in the water storage chamber 21 to the water storage tank 42 through the water inlet pipe and the first water pump connector 431; the water entering the water storage tank 42 can wet the wet membrane 41 through the spray hole; the excess water wetted by the wet membrane 41 can flow into the water inlet tank 5; since the water inlet tank 5 and the water storage chamber 21 are connected through the drain pipe 51, the water that flows into the water inlet tank 5 after wetting the wet membrane 41 can be further returned to the water storage chamber 21 through the drain pipe 51 to participate in the humidification cycle.

[0075] According to an embodiment of the air handling equipment 100 of the present invention, circulating water is used to wet the wet membrane 41. Specifically, the water pump 6 can send water from the water-receiving chamber 21 to the water storage tank 42 through the water inlet pipe and the first water pump connector 431. The water entering the water storage tank 42 can be sprayed out through the spray holes to wet the wet membrane 41, for example, the wet membrane 41 can be wetted from top to bottom, so that the wet membrane 41 can be wetted as a whole, maximizing the humidification capacity of the wet membrane 41. Excess water used to wet the wet membrane 41 can flow into the water inlet tank 5. Since the water inlet tank 5 is connected to the water-receiving chamber 21 through the drain pipe 51, the water that flows into the water inlet tank 5 after wetting the wet membrane 41 can be further returned to the water-receiving chamber 21 through the drain pipe 51 to participate in the humidification cycle. In this way, by using circulating water to wet the wet membrane 41, on the one hand, the wet membrane 41 can be wetted from top to bottom, maximizing the humidification capacity of the wet membrane 41; on the other hand, using circulating water for humidification also helps to reduce the growth of bacteria in the water-containing cavity 21, ensuring the cleanliness of the water circulation and improving the hygiene level. This can better solve the technical problems of insufficient wetting of the wet membrane 41 and low hygiene level in related technologies.

[0076] In some embodiments of the present invention, reference is made to... Figure 4 and Figure 13 The water tank assembly 2 includes a first water tank 22, a water pump 6, and a drain pipe 51, all connected to the first water tank 22. For example, the first water tank 22 may contain a defined water-holding cavity 21. The water pump 6 is connected to the first water tank 22, allowing water from the water-holding cavity 21 to be pumped to the spray nozzles to wet the wet membrane 41. The drain pipe 51 is connected to the first water tank 22, allowing excess water after wetting the wet membrane 41 to flow back into the water-holding cavity 21 through the drain pipe 51 at the bottom of the water tank 5, where it can further participate in the humidification cycle.

[0077] Furthermore, referring to Figure 13 and Figure 15 The wet membrane assembly 4 has a support 43 with a first water pump connector 431, and a first water tank 22 with a second water pump connector 221 and a drain pipe interface 222. A water pump 6 is connected to both the first and second water pump connectors 431 and 221, and a drain pipe 51 is connected to the drain pipe interface 222. For example, the wet membrane assembly 4 includes a wet membrane 41, a support 43, and a fixing frame 44. The first water pump connector 431 is formed on the support 43 and is connected to a water storage tank 42. The first water tank 22 may also have a second water pump connector 221 and a drain pipe interface 222. The water pump 6 is connected to both the first and second water pump connectors 431. The water pump 6 can pump water from the water chamber 21 through the second water pump connector 221 to the water storage tank 42 via the water inlet pipe and the first water pump connector 431, and then spray it out from the spray nozzle to wet the wet membrane 41.

[0078] Combination Figure 6 and Figure 7 The drain pipe 51 and the drain pipe interface 222 can be sealed together. The drain pipe 51 can extend into the water-containing cavity 21 through the drain pipe interface 222 and is spaced apart from the bottom wall of the water-containing cavity 21. In this way, the excess water after wetting the wet film 41 can flow back into the water-containing cavity 21 through the drain pipe 51 at the bottom of the water tank 5 and further participate in the humidification cycle.

[0079] Reference Figure 13 and Figure 15 In some embodiments of the present invention, the first water tank 22 includes a first bottom shell 226 and a first top shell 227 detachably connected to the first bottom shell 226. The second water pump connector 221 may be located on the side wall of the first top shell 227, and the drain pipe interface 222 may be located on the top wall of the first top shell 227.

[0080] Reference Figure 13According to some embodiments of the present invention, a sterilization component 223 is provided inside the first water tank 22. That is, the sterilization component 223 can be disposed inside the water-containing cavity 21 of the first water tank 22, such as on the inner bottom surface of the first bottom shell 226. In this way, the sterilization component 223 can sterilize and disinfect the water in the water-containing cavity 21, thereby reducing bacterial growth, ensuring the cleanliness of the water circulation, and improving the hygiene level.

[0081] Furthermore, the sterilization component 223 can be an electrolyzer. By selecting an electrolyzer as the sterilization component 223, hypochlorous acid, salt, etc., can be added to the water-containing chamber 21 to electrolyze the water, thereby achieving sterilization. Here, the electrolyzer can be connected to an external power supply and perform electrolysis after being powered on. Of course, in other embodiments of the present invention, the sterilization component 223 can also be other components capable of sterilization, such as an ultraviolet lamp.

[0082] The air handling equipment 100 according to an embodiment of the present invention has an electrolyzer installed in the first water tank 22, which can sterilize and disinfect, and is also easy to maintain.

[0083] According to some embodiments of the present invention, a filter element 224 is provided in the first water tank 22, which may be a filter screen or the like. The filter element 224 may be provided in the water-containing cavity 21 of the first water tank 22, so that foreign objects in the water can be filtered out, thereby helping to prevent water pipe blockage.

[0084] Alternatively, the first water tank 22 may also be equipped with a filter element 224 located at the top of the sterilization component 223. That is, the water-containing cavity 21 of the first water tank 22 may also be equipped with a filter element 224, positioned at the top of the sterilization component 223 along the height direction of the first water tank 22. The filter element 224 can be a filter screen, etc., which can be snapped into the water-containing cavity 21. Since a certain amount of salt is added to the water tank during water electrolysis, crystals may form. By setting up the filter element 224, impurities such as salt residue in the water can be filtered out, and water pipe blockage can also be prevented.

[0085] In some embodiments of the present invention, reference is made to... Figure 12 and Figure 13 The water tank assembly 2 also includes a second water tank 23 connected to the first water tank 22, and the second water tank 23 is sealed to the first water tank 22 via a coupling assembly 7. For example, the water tank assembly 2 may also include a second water tank 23, which may define a water storage chamber. The second water tank 23 is connected to the first water tank 22, and the two are sealed to each other via the coupling assembly 7. This allows the first water tank 22 to draw water from the second water tank 23, and the coupling assembly 7 ensures a sealed connection between the first water tank 22 and the second water tank 23, preventing leakage.

[0086] In some embodiments, the volume of the first water tank 22 may be smaller than the volume of the second water tank 23, that is, the first water tank 22 may be a small water tank and the second water tank 23 may be a large water tank.

[0087] Reference Figure 12 and Figure 13 The first water tank 22 and the second water tank 23 can be assembled into a U-shaped structure, which facilitates assembly, manufacturing and maintenance. Figure 12 The illustration shows an embodiment in which a first water tank 22 is provided on the second water tank 23, but the invention is not limited thereto. Two first water tanks 22 may also be provided on the second water tank 23, or the two first water tanks 22 may be symmetrically arranged at both ends of the second water tank 23. In some embodiments, a sterilization component 223, a filter element 224, etc. may also be provided inside the second water tank 23.

[0088] According to some embodiments of the present invention, the second water tank 23 includes a second bottom shell 235 and a second top shell 236 detachably connected to the second bottom shell 235. The connector assembly 7 is located on the side wall of the top shell of the water tank assembly 2 and will not spray water under normal circumstances.

[0089] Reference Figure 13 The connector assembly 7 may include a connector body 71, a suction nozzle 72, and a suction pipe 73. Specifically, the connector body 71 has a first connector 711 and a second connector 712. The first connector 711 is connected to the first mating interface 225 of the first water tank 22, and the second connector 712 is connected to the second mating interface 231 of the second water tank 23. The suction nozzle 72 is located on the inner bottom surface of the second water tank 23. The suction pipe 73 is connected to both the suction nozzle 72 and the connector body 71.

[0090] For example, combining Figure 15 A first mating interface 225 can be formed on the side wall of the first top shell 227 of the first water tank 22, and a second mating interface 231 can be formed on the side wall of the second top shell 236 of the second water tank 23. The second water tank 23 defines a water storage cavity. The connector body 71 has a first connector 711 and a second connector 712. The first connector 711 is connected to the first mating interface 225, and the second connector 712 is connected to the second mating interface 231. A water suction nozzle 72 is located inside the second water tank 23 and on the inner bottom surface of the second bottom shell 235. One end of the water suction pipe 73 is connected to the water suction nozzle 72, and the other end of the water suction pipe 73 is connected to the connector body 71. Thus, water in the water storage cavity of the second water tank 23 can move through the water suction nozzle 72, the water suction pipe 73, and the connector body 71 to the water holding cavity 21 of the first water tank 22, and then further participate in the humidification cycle.

[0091] According to an embodiment of the present invention, the air handling equipment 100 can connect the first water tank 22 and the second water tank 23 through the connector assembly 7, so that the first water tank 22 can be replenished by absorbing water from the second water tank 23.

[0092] Reference Figure 16 The connector body 71 includes: a fixed base 713, a water-absorbing base 714, a water-absorbing head 715, a spring 716, and a sealing element 717. The water-absorbing base 714 is connected to the fixed base 713, and the water-absorbing head 715 is connected to both the water-absorbing base 714 and the fixed base 713. A spring 716 is provided between the water-absorbing head 715 and the fixed base 713, and the water-absorbing head 715 is sealed to the water-absorbing base 714 and the fixed base 713.

[0093] Specifically, a first connector 711 is formed on the water-absorbing base 714, and a second connector 712 is formed on the fixed base 713; the water-absorbing base 714 is connected to the fixed base 713; the water-absorbing head 715 and the spring 716 are disposed between the fixed base 713 and the water-absorbing base 714. The sealing element 717 includes a first sealing element 7171, a second sealing element 7172, and a third sealing element 7173. The first sealing element 7171 is sleeved on the outside of the water-absorbing head 715 and embedded in the inside of one axial end of the water-absorbing base 714; the second sealing element 7172 is sleeved on the other axial end of the water-absorbing base 714; and the third sealing element 7173 is embedded in the other axial end of the water-absorbing base 714. The sealing element 717 ensures the sealing of the connection, which helps to prevent water leakage.

[0094] The suction head 715 has suction holes 7151 formed on its peripheral wall, extending through the wall along its thickness direction. There may be one or more suction holes 7151, and these holes may be spaced apart circumferentially around the suction head 715. A suction cavity 7152 is defined within the suction head 715. A suction pipe connector 7131 is also provided at one end of the fixing base 713 adjacent to the water storage cavity of the second water tank 23 (see reference). Figure 16 and combined Figure 13 The suction pipe connector 7131 is connected to the suction pipe 73. The suction pipe connector 7131 (which can suck water through the suction nozzle 72 and the suction pipe 73) extends along the axial direction of the fixed base 713. The suction hole 7151 is offset from the suction pipe connector 7131.

[0095] In some embodiments of the present invention, the top of the second water tank 23 has a water inlet 232 and a vent 233 adjacent to the water inlet 232, the water inlet 232 being sealed by a rubber stopper 234. For example, see reference... Figure 13The water tank assembly 2 also includes a water inlet 232 for easy water filling. The water inlet 232 can be located on the top wall of the second top shell 236 of the second water tank 23, and can be sealed with a rubber stopper 234. The water tank assembly 2 may also include a vent 233, which can be located on the top wall of the second top shell 236 of the second water tank 23, adjacent to the water inlet 232.

[0096] In some embodiments of the present invention, the second water pump connector 221 is positioned higher than the first mating interface 225 in the height direction of the water tank assembly 2, so as to draw water from the second water tank 23 when the water level in the first water tank 22 is low enough to expose the connector body 71. For example, the second water pump connector 221 is positioned higher than the first mating interface 225 in the height direction of the water tank assembly 2, and the second water pump connector 221 is located at the first mating interface 225, that is, there is a certain height difference between the second water pump connector 221 and the first mating interface 225, so that water can be drawn from the second water tank 23 when the water level in the first water tank 22 is low enough to expose the connector body 71.

[0097] According to an embodiment of the air handling equipment 100 of the present invention, a water circulation humidification scheme is adopted. A drain pipe 51 is provided on the water receiving trough 5 on the air inlet side and / or air outlet side humidified by the fan 3. The drain pipe 51 is connected to the first water tank 22 for drainage. The first water tank 22, through a water pump 6, guides circulating water into a water storage tank 42 on the support 43 of the wet membrane assembly 4. The wet membrane 41 is then wetted by spraying water through the spray holes at the bottom of the water storage tank 42, achieving overall humidification of the wet membrane 41 and maximizing the humidification capacity. Furthermore, the first water tank 22 is also designed with a mating interface (such as a first mating interface 225) that connects to a mating connector assembly 7 (such as a mating connector body 71) at the second water tank 23, so that the water pump 6 can also draw water from the second water tank 23 to achieve overall circulation. Further, an electrolyzer can be added to the first water tank 22 for sterilization and disinfection, ensuring the cleanliness of the circulating water.

[0098] According to an embodiment of the air handling equipment 100 of the present invention, a support frame 43 is designed inside the whole machine. A first water pump connector 431 is provided on the top of the support frame 43 so that water can be added into the water storage tank 42 on the top of the internal fixed frame 44. The water permeates and wets the wet membrane 41 from top to bottom, and then the water is collected through the water receiving tank 5 at the lower end. A drain pipe 51 is located at the low corner of the water receiving tank 5 so that water can be drained. The drain pipe 51 is connected to the first water tank 22 at the bottom. The drained water can be circulated into the humidification system through the drain pipe interface 222 of the first water tank 22 and the water pump 6. Furthermore, the first water tank 22 has an additional interface (first mating interface 225) that connects to the connector body 71 of the second water tank 23. The connector body 71 is designed with a fixing seat 713 and a suction head 715. The suction head 715 has a side opening that is misaligned with the opening of the fixing seat 713. After mating, the spring 716 is pressed to hold the suction head 715 inward, aligning the opening. This allows the water pump 6 to draw water from the second water tank 23 upward through the suction pipe 73, thus preventing water leakage. Further, to prevent foreign matter from flowing into the water pipe and clogging it, a filter element 224, such as a filter screen, is added inside the first water tank 22 for filtration. Additionally, a sterilization component 223, such as an electrolyzer, can be added here for decomposition, sterilization, and disinfection, ensuring the cleanliness of the circulating water.

[0099] According to the air handling equipment 100 of this embodiment, the water pump 6 can send water from the water-containing chamber 21 to the water storage tank 42. The water entering the water storage tank 42 can be sprayed out through the spray holes to wet the wet membrane 41, for example, by wetting the wet membrane 41 from top to bottom. This achieves overall wetting of the wet membrane 41, maximizing its humidification capacity. Excess water used to wet the wet membrane 41 can flow into the water receiving tank 5. Since the water receiving tank 5 is connected to the water-containing chamber 21, the water flowing into the water receiving tank 5 after wetting the wet membrane 41 can flow back into the water-containing chamber 21 to further participate in the humidification cycle. In this way, using circulating water to wet the wet membrane 41 can, on the one hand, wet the wet membrane 41 from top to bottom, maximizing its humidification capacity; on the other hand, using circulating water for humidification also helps reduce bacterial growth in the water-containing chamber 21, improving the hygiene level. This solves the technical problems of insufficient wetting of the wet membrane 41 and low hygiene level in related technologies.
