[0048] The technical solutions in some embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0049] See Figure 43 This disclosure provides an air conditioning system 2000 in some embodiments. The air conditioning system 2000 includes an outdoor unit 2100, an indoor unit 2200, piping 2300, and a humidification device 1000. The outdoor unit 2100 includes an outdoor heat exchanger, and the indoor unit 2200 includes an indoor heat exchanger.

[0050] The outdoor heat exchanger is configured to exchange heat between outdoor air and refrigerant transported within it. For example, in the cooling mode of the air conditioning system 2000, the outdoor heat exchanger operates as a condenser, causing the refrigerant to dissipate heat to the outdoor air and condense; in the heating mode of the air conditioning system 2000, the outdoor heat exchanger operates as an evaporator, causing the refrigerant to absorb heat from the outdoor air and evaporate.

[0051] The indoor heat exchanger is configured to exchange heat between indoor air and refrigerant transported within it. For example, in the cooling mode of the air conditioning system 2000, the indoor heat exchanger operates as an evaporator, causing the refrigerant, after dissipating heat from the outdoor heat exchanger, to absorb heat from the indoor air and evaporate; in the heating mode of the air conditioning system 2000, the indoor heat exchanger operates as a condenser, causing the refrigerant, after absorbing heat from the outdoor heat exchanger, to dissipate heat to the indoor air and condense.

[0052] The humidifier 1000 is installed on the outdoor unit 2100. However, it is not limited to this; the humidifier 1000 can also be installed in other locations, such as on the indoor unit 2200, or on the pipe 2300 between the outdoor unit 2100 and the indoor unit 2200. The humidifier 1000 is connected to the indoor unit 2200 via the pipe 2300, and the heat exchanger of the humidifier 1000 can be switched to form a refrigerant circulation loop with either the outdoor heat exchanger or the indoor heat exchanger.

[0053] When the air conditioning system 2000 operates in heating mode, the heat exchanger of the humidifier 1000 is connected in series with the outdoor heat exchanger, forming a first heat exchanger together. In heating mode, the first heat exchanger operates at a lower temperature, and water vapor in the ambient air easily condenses into liquid water on its surface. When the air conditioning system 2000 operates in cooling mode, the heat exchanger of the humidifier 1000 is connected in series with the indoor heat exchanger, forming a second heat exchanger together. In cooling mode, the second heat exchanger operates at a lower temperature, and water vapor in the ambient air easily condenses into liquid water on its surface. Therefore, by allowing the heat exchanger of the humidifier 1000 to switchably form a refrigerant circulation loop with either the outdoor or indoor heat exchanger, condensation is always generated on the surface of the heat exchanger of the humidifier 1000, thus achieving indoor air humidification.

[0054] This disclosure also provides a humidification device 1000 in some embodiments. See also Figures 1 to 3 The humidification device 1000 includes a base plate 1, a housing 2, a heat exchange component 3, and a humidification component 4. The base plate 1 and the housing 2 form an accommodating space, and the heat exchange component 3 and the humidification component 4 are located within the accommodating space.

[0055] The outer casing 2 is detachably mounted on one side of the base plate 1. The outer casing 2 and the base plate 1 together define a mounting cavity, within which the heat exchange assembly 3 and the humidification assembly 4 are both housed. That is, the base plate 1 is configured to support all components of the humidification device 1000, with the outer casing 2, heat exchange assembly 3, and humidification assembly 4 all located on the same side of the base plate 1. The base plate 1 allows the humidification device 1000 to be installed in different positions, enabling its application in various scenarios and improving its versatility. Furthermore, the entire humidification device 1000 can be installed and disassembled simply by installing or removing the base plate 1 from its corresponding mounting position, making assembly and disassembly relatively easy and efficient.

[0056] The humidification assembly 4 includes a base 41, a water collection component 42, a first air duct assembly 43, and a first fan 44. The heat exchange assembly 3 includes a bracket 31, a heat exchanger 32, a second air duct assembly 33, and a second fan 34. The heat exchange assembly 3 is configured to generate condensate, and the humidification assembly 4 is configured to humidify the indoor air using the condensate.

[0057] In some embodiments, the heat exchanger 32 in the heat exchange assembly 3 is configured to generate condensate through heat exchange. For example, when the humidification device 1000 is operating, air flows through the heat exchanger 32 and exchanges heat with the heat exchanger 32, and water vapor in the air condenses to generate condensate.

[0058] The base 41 is located on the side of the heat exchanger 32 near the base plate 1 (i.e., below the heat exchanger 32). The base 41 has a base air inlet 411 and a base air outlet 412. A water collector 42 is located inside the base 41. Condensate generated by the heat exchanger 32 flows to and is collected by the water collector 42. Air flows into the base 41 from the base air inlet 41, passes through the water collector 42, and then flows out of the base 41 through the base air outlet 412. The water collector 42, located inside the base 41, provides support, fixation, and protection for the water collector 42, extending its service life and thus improving the reliability of the humidification device 1000.

[0059] The first fan 44 is connected to the base 41, meaning the first fan 44 can be connected to either the base air inlet 411 or the base air outlet 412. The first fan 44 is configured to direct airflow passing through the base 41 out through the base air outlet 412. In some embodiments, communication between two components means that the two components are sealed together, allowing airflow to flow between them. See also Figure 3The first fan 44 has a first air inlet 441 and a first air outlet 442. When the first fan 44 is operating, airflow enters the first fan 44 through the first air inlet 441 and exits the first fan 44 through the first air outlet 442. When the first fan 44 is connected to the base air inlet 411, airflow flows from the first fan 44 to the base air inlet 411, and at this time the base air inlet 411 and the first air outlet 442 are sealed together. When the first fan 44 is connected to the base air outlet 412, airflow flows from the base air outlet 412 to the first fan 44, and at this time the base air outlet 412 and the first air inlet 441 are sealed together.

[0060] The first fan 44 is connected to the base air inlet 411 or the base air outlet 412. This connection can be established without any other connecting parts, with the two fans being adjacent and sealed together. Alternatively, other connecting parts can be provided between the first fan 44 and the base air inlet 411 or the base air outlet 412, achieving a sealed connection through these other connecting parts. For ease of description, see [link to description]. Figure 3 In some embodiments, the connection between the first fan 44 and the air outlet 412 of the base is used as an example for illustration. It is understood that the arrangement of the first fan 44 and the air inlet 411 of the base and the corresponding beneficial effects are similar to the arrangement of the first fan 44 and the air outlet 412 of the base and the corresponding beneficial effects, and will not be described again.

[0061] See Figure 3 During the operation of the humidifier 1000, the first fan 44 draws air from the base inlet 411 into the base 41, through the water collector 42 located inside the base 41, and then out through the base outlet 412 to the first inlet 441, and finally out through the first outlet 442. As the air flows through the base 41, the condensate collected by the water collector 42 absorbs heat from the air and vaporizes. The humidified air then flows from the base outlet 412 into the first fan 44 and is finally delivered into the room by the first fan 44. Thus, the condensate generated by the heat exchanger 32 can be used to humidify the indoor air, eliminating the need for manual water addition by the user, making humidification operation more convenient and faster.

[0062] Furthermore, the heat exchanger 32 has a long service life. During long-term operation of the humidifier, the heat exchanger 32 can continuously produce condensate, maintaining a good humidification effect and improving the long-term reliability of the humidifier, effectively extending its service life. In addition, the base 41 is located below the heat exchanger 32, and the water collection component 42 is located inside the base 41, making the internal structure of the humidifier more compact. The condensate produced by the heat exchanger 32 can flow to the water collection component 42 under the action of gravity. The flow path of the condensate is short, and the flow resistance of the condensate can be effectively reduced, allowing the condensate to be quickly collected by the water collection component 42, thereby improving the humidification effect of the humidifier.

[0063] For example, see Figures 1-4 The support 31 of the heat exchange component 3 has a support air inlet 311 and a support air outlet 312. The second fan 34 is connected to the support 31, that is, the second fan 34 can be connected to either the support air inlet 311 or the support air outlet 312. The second fan 34 is configured to send the airflow flowing through the support 31 out of the support air outlet 312. The second fan 34 has a second air inlet 341 and a second air outlet 342. When the second fan 34 is operating, the airflow flows into the second fan 34 from the second air inlet 341 and flows out of the second fan 34 from the second air outlet 342. When the second fan 34 is connected to the air inlet 311 of the bracket, the airflow flows from the second fan 34 to the air inlet 311 of the bracket. At this time, the air inlet 311 of the bracket is sealed to the second air outlet 342. When the second fan 34 is connected to the air outlet 312 of the bracket, the airflow flows from the air outlet 312 of the bracket to the second fan 34. At this time, the air outlet 312 of the bracket is sealed to the second air inlet 341.

[0064] For ease of description, see Figure 3 In some embodiments, the second fan 34 is connected to the air outlet 312 of the bracket as an example. For instance, under the action of the second fan 34, air flows into the bracket from the air inlet 311, passes through the heat exchanger 32 located inside the bracket 31, exchanges heat with the heat exchanger 32 to produce condensate, and then flows from the air outlet 312 into the second air inlet 341, and is finally discharged through the second air outlet 342. The second fan 34 can accelerate the airflow speed, so that more air flows through the heat exchanger 32 per unit time, thereby effectively improving the heat exchange efficiency of the heat exchanger 32, accelerating the production of condensate, and thus improving the humidification effect of the humidification device.

[0065] For example, see Figure 1The base plate 1 has mutually perpendicular length and width directions, and its length dimension (i.e., the length of the base plate 1) is greater than its width dimension (i.e., the width of the base plate 1). The heat exchanger 32 also has mutually perpendicular length and width directions, and its length dimension (i.e., the length of the heat exchanger 32) is greater than its width dimension (i.e., the width of the heat exchanger 32). In some embodiments, such as... Figure 1 As shown, the length direction of the heat exchanger 32 is parallel to the width direction of the base plate 1, and the width direction of the heat exchanger 32 is parallel to the length direction of the base plate 1. Setting the length direction of the heat exchanger 32 parallel to the width direction of the base plate 1 reduces the space occupied by the heat exchanger 32 in the length direction of the base plate 1, allowing sufficient installation space for the first fan 44 and the second fan 34. This makes the internal component layout of the humidification device more convenient and the overall structure of the humidification device more compact. However, it is not limited to this; for example... Figure 16 and 17 As shown, the length direction of the heat exchanger 32 can also be parallel to the length direction of the base plate 1, and the width direction of the heat exchanger 32 can also be parallel to the width direction of the base plate 1. By setting the length direction of the heat exchanger 32 to be parallel to the length direction of the base plate 1, since the base plate 1 is relatively long, the length of the heat exchanger 32 can also be relatively large, thereby generating more condensate and improving the humidification effect of the humidification device 1000.

[0066] For example, see Figure 1 The bracket 31 also has mutually perpendicular length and width directions. The length of the bracket 31 is greater than its width. The base 41 also has mutually perpendicular length and width directions. The length of the base 41 is greater than its width. The length of the bracket 31 is parallel to the width of the base plate 1, and the length of the base 41 is also parallel to the width of the base plate 1. This arrangement reduces the space occupied by the bracket 31 and the base 41 in the length direction of the base plate 1.

[0067] In some embodiments, such as Figure 3 As shown, the air inlet 311 and the air outlet 312 of the bracket are along the first direction D1 ( Figure 3 The air inlets 411 and 412 are arranged sequentially from right to left, with the first direction D1 parallel to the length direction of the base plate 1; the base air inlet 411 and base air outlet 412 are arranged along the second direction D2. Figure 3The fans are arranged sequentially from left to right in the first direction (the second direction is the opposite of the first direction). The second fan 34 is located on one side of the bracket 31 along the first direction D1. For example, the second fan 34 is located on the side near the air outlet 312 of the bracket and is connected to the air outlet 312 of the bracket. The first fan 44 is located on one side of the base 41 along the second direction D2. For example, the first fan 44 is located on the side near the air outlet 412 of the base and is connected to the air outlet 412 of the base. That is, the first fan 44 and the second fan 34 are located on opposite sides of the bracket 31 and the base 41, respectively. For example, the first fan 44 and the second fan 34 are located on opposite sides of the bracket 31 and the base 41, respectively.

[0068] However, this is not the only possibility; the first fan 44 and the second fan 34 can also be located on adjacent sides of the support 31 and the base 41, respectively. For example, see... Figures 16 to 18 The arrangement direction of the support air inlet 311 and support air outlet 312 of the bracket 31 is parallel to the width direction of the base plate 1. The arrangement direction of the base air inlet 411 and base air outlet 412 of the base 41 is also parallel to the width direction of the base plate 1, but the arrangement direction of the support air inlet 311 and support air outlet 312 is opposite to that of the base air inlet 411 and base air outlet 412. The first fan 44 is located on one side of the bracket 31 and base 41 in the length direction parallel to the base plate 1; while the second fan 34 is located on one side of the bracket 31 and base 41 in the width direction parallel to the base plate 1. That is, the first fan 44 and the second fan 34 are located on adjacent sides of the bracket 31 and base 41, respectively.

[0069] By arranging the second fan 34 and the first fan 44 on both sides of the bracket 31 and the base 41 (e.g., opposite sides or adjacent sides), on the one hand, it ensures that the second fan 34 and the first fan 44 have a large heat dissipation space, resulting in better heat dissipation and extending their service life. This also prevents overheating of the humidifier from affecting the normal operation of the second fan 34 and the first fan 44. On the other hand, by arranging only one of the second fan 34 or the first fan 44 on one side of the bracket 31 and the base 41 in the length or width direction parallel to the base plate 1, it provides ample operating space for the installation and disassembly of both fans, making their installation and disassembly easier.

[0070] In some embodiments, see Figure 3 , Figures 5 to 7The humidification device 1000 also includes a water receiving tray 5, which is located between the heat exchanger 32 and the base 41. It should be noted that the water receiving tray 5 can be omitted. The side wall of the water receiving tray 5 closest to the base 41 is a first side wall 51, which has a through opening T1. The side wall of the base 41 closest to the water receiving tray 5 is a second side wall 413, which has a through opening T2. The first opening T1 and the second opening T2 are opposite each other, meaning at least a portion of the second opening T2 is directly below the first opening T1. The condensate generated by the heat exchanger 32 flows into the base 41 through the first opening T1 and the second opening T2. Therefore, no additional piping is needed to input the condensate generated by the heat exchanger 32 into the base 41. The flow direction of the condensate is determined, and the flow path is short, ensuring that the water collecting device 42 collects the condensate.

[0071] Furthermore, since the condensate generated by the heat exchanger 32 can first be collected by the drip tray 5, and then flow out from the first opening T1 and into the base 41 through the second opening T2, the drip tray 5 can prevent the condensate generated by the heat exchanger 32 from flowing to other locations and affecting the normal operation of other components (such as the second fan 34 and the first fan 44), thereby improving the reliability of the humidification device. For example, see... Figures 8 to 12 The first opening T1 and the second opening T2 can both be elongated. The extension direction of the first opening T1 is parallel to the length direction of the water receiving tray 5, and the extension direction of the second opening T2 is parallel to the length direction of the base 41. This allows for a larger area of ​​the first opening T1 and the second opening T2, facilitating the transfer of condensate.

[0072] For example, see Figure 3 , Figures 5 to 7 The water collecting component 42 is opposite to the second opening T2. In conjunction with the above, the second opening T2 is opposite to the first opening T1, and the water collecting component 42 is opposite to the second opening T2. Therefore, the water collecting component 42 is opposite to both the first opening T1 and the second opening T2, and is located directly below the first opening T1 and the second opening T2. In this way, the condensate in the water tray 5, after passing through the first opening T1 and the second opening T2, can flow directly to the water collecting component 42 and be collected by it. This shortens the flow path of the condensate, prevents condensate loss, improves the water collection effect of the water collecting component 42, and thus improves the humidification effect of the humidifier. The water collecting component 42 is detachably installed in the base 41 through the second opening T2. For example, a handle 424 (e.g., ...) can be provided on the side of the water collecting component 42 near the second opening T2. Figure 13As shown, the water collection component 42 can be installed or removed by pulling the handle 424 through the second opening T2. This not only makes the assembly of the water collection component 42 simpler and more reliable, improving the assembly efficiency of the humidifier, but also facilitates the maintenance and upkeep of the water collection component 42, thus extending the service life of the humidifier.

[0073] For example, see Figure 7 and Figure 10 At least a portion of the first sidewall 51 is inclined toward the side closest to the base 41, and the distance between the first opening T1 and the base 41 is less than the distance between the other parts of the first sidewall 51 and the base 41. That is, the first opening T1 is located at the position of the first sidewall 51 closest to the base 41, so that when the condensate generated by the heat exchanger 32 flows to the water receiving tray 5, the condensate can flow entirely along the inclined first sidewall 51 toward the first opening T1 located at the position of the first sidewall 51 closest to the base, and will not stagnate in the water receiving tray 5, thereby allowing the condensate generated by the heat exchanger 32 to flow into the base 41 as much as possible.

[0074] For example, see Figure 9 The drip tray 5 includes a drainage section 52, which is located on the surface of the first sidewall 51 near the base 41 and surrounds the first opening T1. The drainage section 52 protrudes from the surface of the first sidewall 51 near the base and extends into the second opening T2. The drainage section 52 can guide the condensate, directing the condensate flowing out of the first opening T1 towards the second opening T2 and ultimately into the base 41, reducing the risk of condensate flowing to other locations and minimizing condensate loss.

[0075] For example, see Figure 5 and Figure 8 The water collection tray 5 also includes multiple (two or more) support portions 53, which are located on the surface of the first sidewall 51 away from the base 41. Each support portion 53 protrudes from the surface of the first sidewall 51 near the heat exchanger 32, and the multiple support portions 53 are flush with the surface of the heat exchanger 32. At least one (e.g., multiple) support portions 53 are in contact with the heat exchanger 32 to provide support for the heat exchanger 32, allowing the heat exchanger 32 to be installed stably. This ensures that condensate generated at various locations of the heat exchanger 32 can flow smoothly to the water collection tray 5. Furthermore, the support portions 53 can separate the heat exchanger 32 and the water collection tray 5, preventing condensate flowing to the water collection tray 5 from contacting the heat exchanger 32. This avoids the condensate flowing to the water collection tray 5 from affecting the heat exchange effect of the heat exchanger 32, thereby improving the reliability of the humidification device. (Continue to see...) Figure 5 and Figure 8A gap is left between any two adjacent support parts 53, so that while achieving the aforementioned beneficial effects through the support parts 53, the arrangement of the support parts 53 can avoid obstructing the flow of condensate water, allowing the condensate water to flow to the first opening T1 through the gap between the support parts 53.

[0076] For example, see Figure 8 Each support portion 53 has a length direction and a width direction that are perpendicular to each other. The dimension of the support portion 53 along the length direction is larger than its dimension along the width direction. Multiple support portions 53 are arranged in an array, and multiple support portions 53 with the same length direction constitute a support portion row 54 (e.g., ...). Figure 8 (Structure within the dashed box). The support row 54 includes a plurality of first support portions 531 and a plurality of second support portions 532. The dimension of each first support portion 531 along its length is greater than the dimension of each second support portion 532 along its length. Along the arrangement direction of the plurality of support portions 53 in each support row 54, at least one first support portion 531 is provided on both sides of each of the plurality of second support portions 532. That is, the plurality of first support portions 531 are concentrated at both ends of the support row 54, and the plurality of second support portions 532 are located in the middle of the support row 54. For example, see Figure 8 The array of multiple support portions 53 includes three rows of support portions 54, with two rows of support portions 54 located on one side of the first opening T1 and the remaining row of support portions 54 located on the other side of the first opening T1. Each row of support portions 54 includes multiple support portions 53 that are all in the same length direction (i.e., on the same straight line). The multiple support portions 53 include two first support portions 531 and multiple second support portions 532. Along the arrangement direction of the multiple support portions 53 in the row of support portions 54, multiple second support portions 532 are disposed between two first support portions 531. Each second support portion 532 is relatively short, resulting in a larger gap between two adjacent second support portions 532. This further reduces the obstruction of the support portions 53 to the flow of condensate, allowing the condensate to flow quickly to the first opening T1.

[0077] In conjunction with the foregoing, in order to ensure that the condensate can flow into the base 41 through the first opening T1 and the second opening T2, rather than flowing out of the first opening T1 and then flowing to other locations other than the second opening T2, it is necessary to keep the relative positions of the first opening T1 and the second opening T2 fixed, that is, to keep the relative positions of the water receiving tray 5 and the base 41 fixed.

[0078] To achieve this objective, in some embodiments, the water tray 5 and the base 41 can be integrally formed. This eliminates the need for additional components for a secure connection, thereby reducing the number of parts in the entire humidifier and consequently simplifying installation and disassembly, thus improving efficiency.

[0079] In some embodiments, the water tray 5 and the base 41 are two independent components. In this case, they can be fixedly connected using threaded fasteners, snap-fit ​​structures respectively provided on each component, or both methods can be used simultaneously. For example, see... Figures 8 to 9 , Figures 14 to 15 The water receiving tray 5 has a first end face P1 and a second end face P2, and the base 41 has a third end face P3 and a fourth end face P4, which are connected by threaded fasteners. The third end face P3 and the fourth end face P4 are connected by a snap-fit ​​structure.

[0080] For example, the water tray 5 has a first fixing part 56 located on the second end face P2, and the base 41 includes a second fixing part 414 located on the fourth end face P4. The first fixing part 56 is fitted into the second fixing part 414. The second end face P2 and the fourth end face P4 are fixedly connected by the mating first fixing part 56 and the second fixing part 414.

[0081] By fixing the opposite ends of the water receiving tray 5 to the opposite ends of the base 41 respectively, the fixed connection between the water receiving tray 5 and the base 41 can be made more stable. In some embodiments, the arrangement direction of the third end face P3 and the fourth end face P4 can be parallel to the length direction of the base 41, and correspondingly, the arrangement direction of the first end face P1 and the second end face P2 is also parallel to the length direction of the base 41. Alternatively, the arrangement direction of the third end face P3 and the fourth end face P4 can be parallel to the width direction of the base 41, and correspondingly, the arrangement direction of the first end face P1 and the second end face P2 is also parallel to the width direction of the base 41.

[0082] Figures 8 to 9 , Figures 14 to 15In this example, the arrangement directions of the first end face P1 and the second end face P2, and the arrangement directions of the third end face P3 and the fourth end face P4 are all parallel to the length direction of the base 41. The water receiving tray 5 has an extension 55, which is located on the first end face P1 and protrudes from the side of the first end face P1 away from the second end face P2. Furthermore, the portion of the extension 55 protruding from the first end face P1 extends beyond the first sidewall 51 of the water receiving tray 5 and extends towards the side closer to the base 41. A portion of the extension 55 opposite to the base 41 has a first mounting hole H1 through which the portion passes, and the third end face P3 of the base 41 has a second mounting hole H2. During the assembly of the humidifier, the water receiving tray 5 is first placed on the base 41, so that the first end face P1 of the water receiving tray 5 corresponds to the third end face P3 of the base 41, and the first mounting hole H1 is aligned with the second mounting hole H2. Then, threaded fasteners, such as screws, are passed through the first mounting hole H1 and the second mounting hole H2 respectively, so that the first end face P1 of the water receiving tray 5 is fixedly connected to the third end face P3 of the base.

[0083] The first fixing part 56 and the second fixing part 414 can be a plug-in protrusion and a plug-in mating part, respectively. Figures 14 to 15 In this example, the first fixing part 56 is a plug-in protrusion (labeled 56 in the figure), and the second fixing part 414 is a plug-in mating part (labeled 414 in the figure). The plug-in protrusion 56 is located on the second end face P2, and the plug-in protrusion 56 can be formed by a portion of the second end face P2 protruding away from the first end face P1. The plug-in mating part 414 is located on the fourth end face P4, and the plug-in mating part 414 is in contact with the second side wall 413 and protrudes towards the side closer to the water receiving tray 5. For example, the plug-in mating part 414 first extends towards the side closer to the water receiving tray 5, and then bends towards the side closer to the third end face P3. The plug-in mating part 414 and the second side wall 413 together define the plug groove 4141. During the assembly of the humidifier, the insertion protrusion 56 is inserted into the insertion slot 4141, causing the insertion protrusion 56 to abut against the insertion mating part 414, thus achieving a fixed connection between the second end face P2 and the fourth end face P4. This simplifies assembly and improves the efficiency of humidifier assembly. Furthermore, no additional threaded fasteners are needed to fix the second end face P2 and the fourth end face P4 together, reducing the number of threaded fasteners required for humidifier assembly and lowering costs.

[0084] For example, see Figures 14 to 15The base 41 also includes a protrusion 415 located on the third end face P3. The protrusion 415 is in contact with the third end face P3 and protrudes towards the side of the third end face P3 away from the fourth end face P4. The protrusion 325 is arranged around the second mounting hole H2 on the third end face P3. The protrusion 415 is approximately U-shaped and together with the third end face P3 defines a receiving groove 416, which is open at one end near the water tray 5. During the assembly of the humidifier, the portion of the extension 55 opposite to the base 41 is inserted into the receiving groove 416 and finally abuts against the protrusion 415. The protrusion 415 can restrict the installation position of the extension 55, thereby quickly determining the installation position of the water tray and preventing the installation position of the water tray from shifting, thus improving the assembly efficiency of the humidifier.

[0085] For example, see Figures 11 to 12 , Figures 14 to 15 The base 41 includes a guide portion 4131, which is located on the surface of the second side wall 413 near the water receiving tray 5. The guide portion 4131 is in contact with the second side wall 413 and protrudes towards the side near the water receiving tray 5. The extending direction of the guide portion 4131 is parallel to the arrangement direction of the third end face P3 and the fourth end face P4. The guide portion 4131 is located on one side of the water receiving tray 5 and abuts against the water receiving tray 5. For example, the guide portion 4131 can be a straight strip-shaped protrusion. During the assembly of the humidification device, the guide portion 4131 can guide the installation of the water receiving tray 5. For example, the end of the water receiving tray 5 with the first fixing part 56 can first abut against the guide part 4131. The installation position of the water receiving tray 5 can be quickly determined by the guide part 4131. Then, the water receiving tray 5 can be pushed along the extension direction of the guide part 4131 so that the first fixing part 56 and the second fixing part 414 can be accurately matched, and the first mounting hole H1 and the second mounting hole H2 can be aligned, thereby improving the assembly efficiency of the humidification device.

[0086] For example, see Figure 11 and Figure 14 The base 41 has an air inlet 411 and an air outlet 412 opposite to each other. The base 41 also includes a third sidewall 417 located between the air inlet 411 and the air outlet 412 and connected to the second sidewall 413. The third sidewall 417 has a through third opening O3. A water collector 42 is opposite to the third opening O3 and is detachably mounted inside the base 41 through the third opening O3. See, for example... Figure 14The second opening T2 is located on the second sidewall 413 of the base 41 near the heat exchanger 32. The base air inlet 411 and the base air outlet 412 are opposite each other, and their arrangement direction is parallel to the width direction of the base 41. In the same arrangement direction, the third sidewall 417 is located between the base air inlet 411 and the base air outlet 412, and is connected to the second sidewall 413. The third opening O3 is located on and extends through the third sidewall 417. A handle 424 (e.g., ...) can be provided at the end of the water collection component 42 near the third opening O3. Figure 12 As shown, by pulling the handle, the water collection component 42 can pass through the third opening O3, thus enabling installation or removal. During the operation of the humidifier, the second opening T2 is blocked by components such as the heat exchanger 32 and the water tray 5, and the second opening T2 is also used as part of the condensate drainage structure, making it inconvenient to install or remove the water collection component 42. However, the third opening O3 can still be used to install or remove the water collection component 42, allowing for its maintenance and repair.

[0087] For example, see Figures 11 to 12 The base 41 has a second opening T2 and a third opening O3, the arrangement of which is perpendicular to the arrangement of the base air inlet 411 and the base air outlet 412. The second opening T2 and the third opening O3 are connected. The arrangement of the second opening T2 and the third opening O3 is parallel to the length direction of the base 41, while the arrangement of the base air inlet 411 and the base air outlet 412 is parallel to the width direction of the base 41. The connection between the second opening T2 and the third opening O3 increases their area, reducing the possibility of interference between the water collector 42 and the water tray 5 or the base 41 when installing or removing the water collector 42 through the second opening T2 or the third opening O3, thus simplifying the installation or removal of the water collector 42.

[0088] In some embodiments, see Figures 11 to 12 The base 41 also includes a limiting portion 4132, which is located on the second side wall 413. The limiting portion 4132 is in contact with the second side wall 413 and protrudes from the second side wall 413 towards the side closer to the water receiving tray 5. The limiting portion 4132 extends across the second opening T2, and the extending direction of the limiting portion 4132 is perpendicular to the arrangement direction of the second opening T2 and the third opening O3. Figure 6As shown, the water receiving tray 5 has a limiting groove 511 located on the first side wall 51, and the limiting part 4132 is inserted into the limiting groove 511. For example, the limiting part 4132 is a straight protrusion, the arrangement direction of the second opening T2 and the third opening O3 is parallel to the length direction of the base 41, and the extension direction of the limiting part 4132 is parallel to the width direction of the base 41. The limiting part 4132 can play a good reinforcing role, avoiding damage at the connection position of the second opening T2 and the third opening O3, thereby improving the reliability of the humidification device. Moreover, the limiting part 4132 can play a good stopping role, which can confine the water collecting component 42 within the base 41, making the installation of the water collecting component 42 more secure. The shape of the limiting groove 511 is adapted to the shape of the limiting part 4132. During the assembly of the humidification device, when the first fixing part 56 and the second fixing part 414 are properly engaged, the limiting part 4132 is accurately engaged in the limiting groove 511, allowing the operator to accurately determine whether the water tray 5 is properly installed. Alternatively, the positions of the limiting part 4132 and the limiting groove 511 can be interchanged; that is, the limiting part 4132 can be placed on the first side wall 51 of the water tray 5, and the limiting groove 511 can be placed on the second side wall 413 of the base 41.

[0089] See Figures 14 to 15 The limiting groove 511 and the extension 55 are located on the same side of the water receiving tray 5 along its length, and the limiting part 4132 and the protrusion 415 are located on the same side of the base 41 along its length. When installing the water receiving tray, the end of the water receiving tray with the insertion protrusion 56 first abuts against the guide part 4131, and then the water receiving tray is pushed along the extension direction of the guide part 4131. The insertion protrusion 56 abuts against the insertion mating part 414. At this time, the limiting part 4132 is accurately fitted in the limiting groove 511. At the same time, the part of the extension 55 opposite to the base 41 is inserted into the receiving groove 416 and finally abuts against the protrusion 415. Finally, the threaded fastener is passed through the corresponding first mounting hole H1 and second mounting hole H2. When disassembling the water receiving tray 5, first remove the threaded fasteners, then pull the extension 55 out of the receiving groove 416, the limiting part 4132 out of the limiting mating groove 511, and finally pull the insertion protrusion 56 out of the insertion mating part 414.

[0090] For example, see Figure 3 , Figures 5 to 7 ( Figure 3 For a magnified view of section H, please refer to Figure 7The base 41 also includes a first recess 418 and a second recess 419, which are located on the bottom wall of the base 41 away from the heat exchanger 32 and near the surface of the heat exchanger 32 (hereinafter referred to as the base surface). A water collection element 42 is disposed within the first recess 418. The first recess 418 communicates with the second recess 419, and the depth of the first recess 418 is greater than the depth of the second recess 419. The base 41 also includes an overflow hole 4191 (see also...). Figure 13 The overflow hole 4191 is located in the second recess 419. The overflow hole 4191 penetrates the second recess 419. For example, the first recess 418 is formed by a portion of the base surface recessed towards the side away from the heat exchanger 32, and the second recess 419 is similarly recessed. Neither the first recess 418 nor the second recess 419 penetrates the bottom wall of the base 41 away from the heat exchanger 32. Because the first recess 418 is deeper, more condensate can be collected in the first recess 418. Therefore, by placing the water collector 42 in the first recess 418, more condensate can be collected by the water collector 42, ensuring the water collection effect of the water collector 42, and thus ensuring the humidification effect of the humidification device. Furthermore, when too much condensate is collected in the first recess 418, the condensate can flow into the second recess 419, which communicates with the first recess 418, and then be discharged through the overflow hole 3291 that passes through the second recess 419. This avoids the adverse effects that may result from excessive condensate remaining in the base 41. Since the depth of the first recess 418 is greater than that of the second recess 419, not all the condensate in the first recess 418 will be discharged through the second recess 419 and the overflow hole 4191, thus ensuring the condensate collection effect of the water collecting component 42.

[0091] For example, see Figures 1 to 3 The first air duct assembly 43 of the humidification component 4 is configured to connect the base 41 and the first fan 44. For example, the first air duct assembly 43 is located within the mounting cavity, with one end connected to the base 41 and the other end connected to the first fan 44. In some embodiments, see Figure 3One end of the first air duct assembly 43 is connected to the base air outlet 412, and the other end is connected to the first air inlet 441 of the first fan 44. Air flows into the base 41 from the base air inlet 411, passes through the base air outlet 412 and the first air duct assembly 43 in sequence, and is then discharged by the first fan 44. However, this is not the only embodiment. In other embodiments, one end of the first air duct assembly 43 is connected to the first air outlet 442 of the first fan 44, and the other end is connected to the base air inlet 411 of the base 41. Air flows into the first fan 44 from the first air inlet 441, flows through the first air outlet 442 of the first fan 44 to the first air duct assembly 43, then flows through the first air duct assembly 43 to the base air inlet 411, and finally flows out from the base air outlet 412. The first air duct assembly 43 can guide the airflow inside it, making the airflow smoother, thereby effectively reducing the noise of the humidifier.

[0092] This disclosure does not impose excessive restrictions on the structure of the first air duct assembly 43. For example, the first air duct assembly 43 may be a single, integrated component, see [link to relevant documentation]. Figures 1-3 The air supply volute is shown. For example, the first air duct assembly 43 is a separate component; see [reference needed]. Figures 16-19 As shown.

[0093] See Figures 16-19 The first air duct assembly 43 includes a detachable first air duct section 431 and a second air duct section 432. One end of the first air duct section 431 is connected to the base 41, and the other end is connected to the second air duct section 432. One end of the second air duct section 432 is connected to the first fan 44, and the other end is connected to the first air duct section 431. When the first fan 44 is connected to the base outlet 412, air flows into the base 41 from the base inlet 411, flows sequentially through the base outlet 412, the first air duct section 431, and the second air duct section 432, and is then discharged by the first fan 44. The arrangement of the first air duct section 431 and the second air duct section 432 also reduces the noise of the humidifier. In addition, both the first air duct section 431 and the second air duct section 432 are detachable, that is, the first air duct section 431 and the second air duct section 432 are detachably and sealed in connection. One end of the first air duct section 431 is detachably and sealed to the base 41, and one end of the second air duct section 432 is detachably and sealed to the first fan 44, so that the first air duct section 431 and the second air duct section 432 can be disassembled to clean their interiors and the interior of the base 41, thereby extending the service life of the humidifier.

[0094] For example, see Figures 20 to 22The first fan 44 has a first air inlet 441 and a first air outlet 442. Airflow enters the first fan 44 through the first air inlet 441 and exits the first fan 44 through the first air outlet 442. The humidification device also includes a duct connector 6. The first air inlet 441 of the first fan 44 is connected to the base 41, and the first air outlet 442 of the first fan 44 is connected to the duct connector 6. That is, the humidified air generated by the humidification device is finally sent out to the outside of the humidification device through the duct connector 6. The duct connector 6 can be used to connect the first air outlet 442 of the first fan 44 to other devices (such as indoor units), so that the humidified air generated by the humidification device can be delivered to other devices after being sent out through the first air outlet 442 of the first fan 44, thereby enabling the device to have a humidification function.

[0095] For example, the duct connector 6 in the humidifier is a detachable duct connector 6, so that during the use of the humidifier, the duct connector 6 can be periodically removed from the humidifier for cleaning and maintenance, thereby extending the service life of the humidifier.

[0096] The detachable connection method between the duct connector 6 and the first fan 44 can be selected and configured according to the application scenario and user needs, and this disclosure does not impose excessive restrictions in this regard. For example, the duct connector 6 and the first fan 44 can be connected by at least one of a threaded fastening structure (e.g., matching screws and nuts) and a snap-fit ​​structure. See, for example... Figures 20 to 22 The first fan 44 has a chute 443 (e.g., Figure 23 As shown), one end of the chute 443 has a chute opening 4431, and the duct connector 6 has a sliding rib 61 (as shown). Figure 24 As shown, the sliding rib 61 passes through the sliding groove opening 4431 and is movably fitted within the sliding groove, so that the duct connector 6 is detachably connected to the first fan 44. In some embodiments, the duct connector 6 has a sliding groove, and the first fan 44 is provided with a sliding rib.

[0097] In humidifiers, see Figures 23 to 24The duct connector 6 has two sliding ribs 61, which are respectively located on the edges of two opposite sidewalls of the duct connector 6. The arrangement direction of these two sliding ribs 61 (hereinafter referred to as the first arrangement direction) is perpendicular to the arrangement direction of the first fan 44 and the duct connector 6. Correspondingly, the first fan 44 has two sliding grooves 443, which are arranged parallel to the first arrangement direction. The groove opening 4431 of each groove 443 is located at one end of the groove 443, and the arrangement direction of the groove openings 4431 of the two grooves 443 is also parallel to the first arrangement direction. The side of the two grooves 443 that is close to each other is open. However, it is not limited to this; the first fan 44 may also have two sliding ribs 61, and the duct connector 6 may also have two sliding grooves 443. When assembling the first fan 44 and the duct connector 6, the two sliding ribs 61 are slid into the two sliding grooves 443 respectively, which can realize the connection between the first fan 44 and the duct connector 6, making the assembly of the two accurate and fast.

[0098] In some embodiments, the duct connector 6 includes a body 62, and the first fan 44 has a body mating groove 444. A sliding rib 61 is disposed on the side of the body 62 near the body mating groove 444, the sliding rib 61 is connected to the body 62, and the edge of the sliding rib 61 protrudes beyond the edge of the body 62. The body mating groove 444 is located on the side of the sliding groove 443 near the duct connector 6. In the assembled humidification device, a portion of the body 62 extends into the body mating groove 444, thereby ensuring communication between the first fan 44 and the duct connector 6. However, this is not limited to this; the first fan 44 may include a body 62 and two sliding ribs 61, and the duct connector 6 may include two sliding grooves 443 and one body mating groove 444. During assembly, the two sliding ribs 61 slide into the two sliding grooves 443 respectively, while the body 62 slides along the same trajectory as the sliding ribs 61 and engages in the body mating groove 444, thereby ensuring high assembly efficiency while maintaining communication between the first fan 44 and the duct connector 6. In addition, both the slide groove 443 and the body mating groove 444 have a labyrinth-shaped sealing structure, which can improve the sealing of the connection between the first fan 44 and the duct joint 6 while achieving the aforementioned beneficial effects.

[0099] For example, see Figures 20 to 24The duct connector 6 has a mating groove 63, and the first fan 44 has a mating rib 445. The mating rib 445 and the mating groove 63 are located on the side of the slide groove 443 away from the base plate 1. In the assembled humidifier, the mating rib 445 fits into the mating groove 63. For example, along the arrangement direction of the two slide grooves 443, the mating rib 445 is located between the two slide grooves 443. Along the arrangement direction of the two slide ribs 61, the mating groove 63 is located between the two slide ribs 61. Both the mating rib 445 and the mating groove 63 are located on the side of the slide groove 443 away from the base plate 1. During assembly, the mating groove 63 moves downwards (i.e., towards the side closer to the base plate 1) and abuts against the mating rib 445, thereby preventing the duct connector 6 from moving downwards relative to the first fan 44. This makes the relative position of the duct connector 6 and the first fan 44 more stable, improving the reliability of the humidifier.

[0100] It should be noted that the sliding groove 443 and the mating rib 445 can both be provided on the first fan 44; or, the sliding groove 443 can be provided on the first fan 44, and the mating rib 445 can be provided on the duct joint 6. Similarly, the sliding rib 61 and the mating groove 63 can both be provided on the duct joint; or, the sliding rib 61 can be provided on the duct joint 6, and the mating groove 63 can be provided on the first fan 44.

[0101] For example, see Figures 20 to 22 ,as well as Figure 25 The first fan 44 and the duct connector 6 can also be connected by a snap-fit ​​structure. For example, the snap-fit ​​structure includes a first snap-fit ​​member 446 and a second snap-fit ​​member 64. The first snap-fit ​​member 446 is disposed on the first fan 44 and has a latch 4461 located on the side of the first snap-fit ​​member 446 closer to the duct connector 6. The second snap-fit ​​member 64 is disposed on the duct connector 6 and cooperates with the latch 4461 to prevent the sliding rib 61 from moving in the direction of disengaging from the sliding groove 443. However, it is not limited to this; the first snap-fit ​​member 446 can also be disposed on the duct connector 6, and the second snap-fit ​​member 64 can also be disposed on the second fan 44. Both the mating rib 445 and the mating groove 63 are located on the side of the slide groove 443 away from the base plate 1. The mating of the mating rib 445 and the mating groove 63 ensures that the duct connector 6 will not move downward relative to the first fan 44 after the two are assembled. The mating of the first fastener 446 and the second fastener 64 ensures that the duct connector 6 will not move upward relative to the first fan 44 after the two are assembled, further ensuring that the relative position of the duct connector 6 and the first fan 44 will not change, thus improving the reliability of the humidification device. It is understood that the positions of the first fastener 446 and the second fastener 64 can be specifically set according to actual requirements.

[0102] For example, see Figure 21 and Figure 25The second fastener 64 has a guide surface 641 on the side near the first fastener 446. Along the arrangement direction from the first fastener 446 to the second fastener 64, the distance between the guide surface 641 and the first fastener 446 gradually decreases. That is, the portion of the guide surface 641 farther from the duct connector 6 is inclined towards the side closer to the first fastener 446. However, this is not a limitation; the first fastener 446 can also be provided on the duct connector 6, and the second fastener 64 can also be provided on the first fan 44. Therefore, the guide surface 641 can play a guiding role during the installation of the duct connector 6, allowing the duct connector 6 to be quickly assembled onto the first fan 44.

[0103] For example, instead of a snap-fit ​​structure, two threaded fastening structures can be provided, perpendicular to the arrangement direction of the first fan 44 and the duct connector 6. The two threaded fasteners are located on opposite sides of the connection position of the first fan 44 and the duct connector 6, and the first fan 44 and the duct connector 6 can be fixedly connected by the two threaded fasteners.

[0104] For example, see also Figure 20 The first fan 44 and the duct connector 6 can be fixedly connected by both a snap-fit ​​structure and a threaded fastening structure. At this time, perpendicular to the arrangement direction of the first fan 44 and the duct connector 6, the snap-fit ​​structure and the threaded fastening structure are located on opposite sides of the connection position of the first fan 44 and the duct connector 6, thereby making the fixed connection between the first fan 44 and the duct connector 6 more reliable.

[0105] In conjunction with the foregoing, the structure of the first fan 44 and the duct connector 6 is as follows: Figures 20 to 25 As shown, when installing the duct connector 6, the duct connector 6 can be moved relative to the first fan 44 towards the base plate 1 so that the sliding rib 61 of the duct connector 6 is inserted into the sliding groove 443 of the first fan 44, and at the same time, the body 62 of the duct connector 6 fits into the body mating groove 444 of the first fan 44. When the mating groove 63 of the duct connector 6 abuts against the mating rib 445 of the first fan 44, the second fastener 64 fits perfectly into the bayonet 4461 of the first fastener 446. Then, threaded fasteners such as screws can pass through the duct connector 6 and be threadedly connected to the first fan 44. Thus, the installation of the duct connector 6 is completed. When disassembling the duct connector 6, first remove the threaded fasteners on the duct connector 6, then disengage the second clip 64 from the slot 4461 of the first clip 446, and finally move the sliding rib 601 of the duct connector 6 away from the base plate 1 to the side where it is disengaged from the sliding groove 443 of the first fan 44. Thus, the disassembly of the duct connector 6 is completed.

[0106] For example, see Figures 26 to 27The base plate 1 includes two parallel guide ribs 11, which are positioned near the first air duct assembly 43 and define a guide groove 12. The first air duct assembly 43 includes a guide block 433, which is positioned near the base plate 1 and extends between the two guide ribs 11. For example, see... Figures 26 to 27 Each guide rib 11 protrudes from the base plate 1 towards the side closest to the first air duct assembly 43. The guide rib 11 can be straight. The extending direction of the two guide ribs 11 is parallel to the length direction of the base plate 1, and the arrangement direction of the two guide ribs 11 is parallel to the width direction of the base plate 1. In the assembled humidifier, the guide block 433 abuts against both guide ribs 11. The guide ribs 11 can restrict the installation position of the guide block 433, and correspondingly restrict the installation position of the first air duct assembly 43. During the assembly of the humidifier, the installation position of the first air duct assembly 43 can be quickly determined by the guide ribs 11, ensuring the accuracy of the installation position of the first air duct assembly 43. Furthermore, during installation, it is only necessary to push the guide block 433 between the two guide ribs 11 in a direction parallel to the extending direction of the guide ribs 11, making the installation method relatively simple and convenient to operate.

[0107] For example, see Figures 27 to 28 One of the two guide ribs 11 has a mounting guide surface 111 on the side closer to the other, located at the end of the guide rib 11 away from the base plate 1. Along the arrangement direction from the base plate 1 to the guide ribs 11, the mounting guide surface 111 of one guide rib 11 is inclined towards the side away from the other guide rib 11. For example, each guide rib 11 has a mounting guide surface 111 on the side closer to the other guide rib 11, located at the end of that guide rib 11 away from the base plate 1, and the portion of the mounting guide surface 111 farther from the base plate 1 is inclined further towards the side away from the other guide rib 11, meaning the distance between the two mounting guide surfaces 111 increases. This arrangement prevents interference between the guide block 433 and the guide rib 11 during the installation of the first air duct assembly 43, allowing the guide block 433 to be quickly assembled into the guide groove 12.

[0108] For example, the installation direction of the first air duct assembly 43 is opposite to the air inlet and outlet directions of the first air duct assembly 43. See, for example, Figure 26 Since the airflow direction in the first air duct assembly 43 is from left to right (i.e., the direction shown by the arrow in the figure), the installation direction of the first air duct assembly 43 is from right to left. This setting facilitates operation by the operator during installation, allowing the guide block 433 to be quickly and accurately assembled into the guide groove 12, and also avoids interference between the first air duct assembly 43 and other surrounding components.

[0109] See Figures 26 to 27The base plate 1 also includes at least one screw post 13, and the first air duct assembly 43 also includes at least one screw seat 434. The screw seat 434 is connected to the screw post 13 by screws, thereby making the installation of the first air duct assembly 43 more secure. For example, the base plate 1 includes two screw posts 13, and two guide ribs 11 are disposed between the two screw posts 13 along the width direction of the base plate 1. During installation, the screw passes through the corresponding screw seat 434 and connects to the corresponding screw post 13, thereby securely fixing the first air duct assembly 43 to the base plate 1.

[0110] See Figures 26 to 27 , Figures 29 to 30 A mounting groove 4341 is formed on the side of the screw seat 434 near the base plate 1, and the screw post 13 fits into the mounting groove 4341. During installation, the mounting groove 4341 acts as a guide to ensure that the guide block 433 of the first air duct assembly 43 can be accurately installed in the guide groove 12 of the base plate 1. Furthermore, after installation, the outer peripheral surface of the screw post 13 abuts against the inner peripheral surface of the mounting groove 4341, further preventing the first air duct assembly 43 from moving and making the installation more stable. In addition, when the outer peripheral surface of the screw post 13 abuts against the inner peripheral surface of the mounting groove 4341, the guide block 433 and the guide rib 11 are also perfectly assembled, thereby improving assembly efficiency.

[0111] For example, see Figures 29 to 30 The mounting groove 4341 has an open end OE and a closed end CE. The closed end CE abuts against the screw post 13, and the open end OE is located on the side of the closed end CE away from the screw post 13. From the open end OE to the closed end CE, the distance between the directly opposite portions of the surface of the mounting groove 4341 gradually decreases, meaning the mounting groove 4341 is generally funnel-shaped. During installation, the screw post 13 is inserted into the mounting groove 4341 from the open end OE and finally abuts against the closed end CE, thereby reducing the interference between the screw post 13 and the screw seat 434 and ensuring that the screw post 13 can be quickly fitted into the mounting groove 4341.

[0112] For example, see Figures 1 to 3 , Figures 31 to 32 The second air duct assembly 33 of the heat exchange component 3 is configured to connect the support 31 and the second fan 34. For example, one end of the second air duct assembly 33 has a first connecting port CP1, and the other end has a second connecting port CP2. The first connecting port CP1 is connected to the support 31, and the second connecting port CP2 is connected to the second fan 34. The second fan 34 has a second air inlet 341 and a second air outlet 342. Airflow enters the second fan 34 through the second air inlet 341 and exits the second fan 34 through the second air outlet 342. Figure 1 and Figure 31The following example illustrates the connection between the first connecting port CP1 and the air outlet 312 of the bracket, and the second connecting port CP2 and the second air inlet 341. The second air duct assembly 33 guides the airflow between the second fan 34 and the bracket 31, making the airflow smoother and effectively reducing the noise of the humidifier 1000. The structure of the second air duct assembly 33 can be set with reference to the structure of the first air duct assembly 43 described above, and will not be repeated here.

[0113] To ensure a reliable and secure connection between the second duct assembly 33 and the second fan 34, thereby guaranteeing a tight seal between them, see [reference needed]. Figures 31 to 33 The second fan 34 includes a third fixing part 343, and the second air duct assembly 33 includes a fourth fixing part 331. One of the third fixing part 343 and the fourth fixing part 331 is inserted into the other. Therefore, there is no need to use a threaded fastening structure; the second fan 34 and the second air duct assembly 33 are fixedly connected solely by the cooperation of the third fixing part 343 and the fourth fixing part 331. This reduces the number of threaded fasteners required for assembling the humidification device and lowers costs.

[0114] For example, one of the third fixing part 343 and the fourth fixing part 331 can be Figure 33 The bump shown can be another one. Figure 33 The diagram shows a protrusion-fitting portion into which a protrusion is inserted. For example, when the third fixing portion is a protrusion (not shown in the figure) and the fourth fixing portion is a protrusion-fitting portion (not shown in the figure), the second fan 34 includes a protrusion, the second air duct assembly 33 includes a protrusion-fitting portion, and the third fixing portion is inserted into the fourth fixing portion to achieve a fixed connection between the second fan 34 and the second air duct assembly 33. See also, for another example... Figures 32 to 33 When the third fixing part 343 is a protrusion mating part and the fourth fixing part 331 is a protrusion, the second air duct assembly 33 includes a protrusion, and the second fan 34 includes a protrusion mating part. The fourth fixing part 331 is inserted into the third fixing part 343 to achieve a fixed connection between the second fan 34 and the second air duct assembly 33. For simplicity, the following explanation uses the third fixing part 343 as a protrusion mating part and the fourth fixing part 331 as a protrusion as an example.

[0115] See Figures 31 to 34The opening connecting the second fan 34 and the second air duct assembly 33 is the second air inlet 342. A protrusion mating part 343 is located on the outer periphery of the second air inlet 342, and the opening of the protrusion mating groove defined by the protrusion mating part 343 faces the second fan 34. A protrusion 331 is located on the outer periphery of the second connecting port CP2 of the second air duct assembly 33. During assembly, the second connecting port CP2 of the second air duct assembly 33 can be brought into contact with the second air inlet 342 first. Then, relative to one of the second fan 34 and the second air duct assembly 33, the other can be rotated clockwise or counterclockwise, causing the protrusion 331 to insert into the protrusion mating groove, thereby achieving the engagement of the protrusion 331 and the protrusion mating part 343, and thus achieving a fixed connection between the second fan 34 and the second air duct assembly 33, resulting in high assembly efficiency. In addition, it ensures good sealing at the connection between the second fan 34 and the second air duct assembly 33, preventing air leakage at the connection. This allows the heat exchanger 32 to exchange heat with sufficient air and generate enough condensate, thereby ensuring the humidification effect of the humidification device.

[0116] For example, the second air duct assembly 33 includes a plurality of protrusions 331, and the second fan 34 includes a plurality of protrusion mating portions 343. A gap is left between any two adjacent protrusions 331, and a gap is also left between any two adjacent protrusion mating portions 343. See, for example... Figure 34 The number of protrusions 331 and protrusion mating parts 343 can both be five. The five protrusion mating parts 343 can be arranged circumferentially along the second air inlet 342, and the five protrusions 331 can be arranged circumferentially along the second connecting port CP2, thereby ensuring that the connection between the second fan 34 and the second air duct assembly 33 has good sealing performance.

[0117] Understandable, Figure 34 The five protrusion mating portions 343 and five protrusions 331 shown are for illustrative purposes only. The number of protrusions 331 and protrusion mating portions 343 can also be other values, and this disclosure does not impose excessive limitations on them.

[0118] For example, see Figure 32 , Figures 34 to 35 The protrusion 331 has a protrusion guide surface 3311, which is located at one end of the protrusion 331 in the circumferential direction. In some embodiments, the protrusion 331 has two protrusion guide surfaces 3311, which are located at opposite ends of the protrusion 331 in the circumferential direction. The protrusion guide surfaces 3311 are inclined toward the central axis of the second air duct assembly 33. During assembly, when the protrusion 331 is rotated relative to one of the second fan 34 and the second air duct assembly 33 to insert into the protrusion mating part 343, the arrangement of the protrusion guide surfaces 3311 can prevent interference between the two, allowing the protrusion 331 to be quickly inserted into the protrusion mating part 343.

[0119] For example, see Figures 36 to 38 The second air duct assembly 33 includes a first sealing protrusion 332, and the second fan 34 includes a first sealing groove 344. The first sealing protrusion 332 extends into and mates with the first sealing groove 344. For example, the first sealing groove 344 surrounds the second air inlet 342, and the first sealing protrusion 332 surrounds the second connecting port CP2. However, it is not limited to this; the second air duct assembly 33 may include the first sealing groove, and the second fan 34 may include the first sealing protrusion. By setting the first sealing protrusion 332 to extend into the first sealing groove 344, a sealing structure is formed between the second air inlet 342 and the second connecting port CP2 of the second air duct assembly 33, which can reduce the risk of air leakage at the connection between the two.

[0120] The end of the first sealing protrusion 332 closest to the first sealing groove 344 is the top, and the end of the first sealing protrusion 332 furthest from the first sealing groove 344 is the bottom. The end of the first sealing groove 344 closest to the first sealing protrusion 332 is the opening, and the end of the first sealing groove 344 furthest from the first sealing protrusion 332 is the bottom. The size of the first sealing protrusion 332 gradually decreases from the bottom to the top, and the size of the first sealing groove 344 gradually decreases from the opening to the bottom, with the opening of the first sealing groove 344 being larger than the bottom of the first sealing protrusion 332. Correspondingly, the opening of the first sealing groove 344 is larger than the top of the first sealing protrusion 332. During assembly, aligning the top of the first sealing protrusion 332 with the opening of the first sealing groove 344 is relatively easy, avoiding interference between the two when the top of the first sealing protrusion 332 extends into the opening of the first sealing groove 344, allowing the first sealing protrusion 332 to be quickly installed into the first sealing groove 344.

[0121] For example, see Figure 37 and Figure 39Similarly, the second air duct assembly 33 includes a second sealing protrusion 334, and the bracket 31 includes a second sealing groove 313. The second sealing protrusion 334 extends into and mates with the second sealing groove 313. For example, the second sealing protrusion 334 surrounds the first connecting port CP1, and the second sealing groove 313 surrounds the bracket air inlet 311. Alternatively, the second air duct assembly 33 may include a second sealing groove, and the bracket 31 may include a second sealing protrusion. A sealed connection is formed between the bracket air inlet 311 of the bracket 31 and the first connecting port CP1 of the second air duct assembly 33, reducing the risk of air leakage at the connection point. Furthermore, the end of the second sealing protrusion 334 near the second sealing groove 313 is the top, and the end of the second sealing protrusion 334 away from the second sealing groove 313 is the bottom. The end of the second sealing groove 313 near the second sealing protrusion 334 is the opening, and the end of the second sealing groove 313 away from the second sealing protrusion 334 is the bottom. The second sealing protrusion 332 gradually decreases in size from bottom to top, and the second sealing groove 344 gradually decreases in size from opening to bottom, with the opening of the second sealing groove 344 being larger than the bottom of the second sealing protrusion 332. Correspondingly, the opening of the second sealing groove 344 is larger than the top of the second sealing protrusion 332. For example, see... Figure 32 and Figure 34 The second air duct assembly 33 and the second fan 34 can be further connected by at least one (e.g., one) threaded fastener. The second air duct 33 includes a lug 333 located on the outer periphery of the second communication port CP2. The lug 333 engages with the second communication port CP2 and extends in a direction away from the center of the second communication port CP2, and the lug 333 does not contact any of the protrusions 331. A threaded fastener, such as a screw, can pass through the lug 333 and be threadedly connected to the second fan 34 to ensure a secure connection between the second air duct assembly 33 and the second fan 34.

[0122] In accordance with the foregoing, during the installation of the humidifier, the first sealing protrusion 332 can be inserted into the first sealing groove 344 first. Then, relative to one of the second fan 34 and the second air duct assembly 33, the other can be rotated to allow the protrusion 331 to be inserted into the protrusion mating groove of the protrusion mating part 343. Finally, a threaded fastener, such as a screw, passes through the lug 333 to thread the second fan 34 and the second air duct assembly 33 together, completing the installation. During disassembly, the threaded fastener on the lug 333 can be removed first. Then, relative to one of the second fan 34 and the second air duct assembly 33, the other can be rotated to allow the protrusion 331 to disengage from the protrusion mating groove of the protrusion mating part 343. Finally, the first sealing protrusion 332 can be disengaged from the first sealing groove 344, completing the disassembly.

[0123] In some embodiments, see Figures 40-42The water collecting component 42 includes a water collecting component body 421, a frame 422, and a handle 424. The water collecting component body 421 is located within the frame 422. In the assembled humidification device, the handle of the water collecting component 42 is positioned near the second opening T2 or the third opening O3. The water collecting component body 421 is, for example, a wet film, which is a polymer composite material based on plant fiber or glass fiber, possessing good water absorption and evaporation properties. The water collecting component 42 also includes a guide 423 connected to the frame 422, located on the side of the water collecting component 42 away from the base plate 1. Along the arrangement direction of the water collecting component 42 and the base plate 1, the distance between directly opposite portions of the surface of the guide 423 gradually decreases. That is, the farther away from the base plate 1 (the closer to the second opening T2), the greater the distance between directly opposite portions of the surface of the guide 423. Condensate flows from the second opening T2 to the guide 423, and then from the guide 423 to the water collection body 421 for collection. The closer to the second opening T2, the greater the distance between the directly opposite parts on the surface of the guide 423, thus enabling the collection of condensate dripping from the second opening T2 over a larger area. The condensate is then concentrated in the water collection body 421, which improves the condensate collection effect.

[0124] For example, see Figure 42 The frame 422 may include a first sub-frame 4221 and a second sub-frame 4222, which are detachably connected. The water collection body 421 is located between the first sub-frame 4221 and the second sub-frame 4222. Because the first sub-frame 4221 and the second sub-frame 4222 are detachable, it is easy to remove the water collection body 421 for cleaning and replacement, thereby improving the reliability of the humidification device.

[0125] For example, see Figure 3 The humidification device also includes a heater HT, which is located between the air inlet 411 of the base and the water collection component 42. That is, the heater HT is also located inside the base 41, upstream of the water collection component 42 along the airflow direction inside the base 41. Air flows into the base 41 through the air inlet 411 under the action of the first fan 44, then flows through the heater HT and is heated. The heated air then flows through the water collection component 42, where the moisture absorbs the heat from the air and evaporates. The resulting humidified air flows out through the air outlet 412 of the base for humidification. The airflow is first heated before flowing through the water collection component 42, which increases the vaporization and evaporation rate of the condensate on the water collection component 42, thereby effectively improving the humidification effect of the humidification device.
