[0054] Humidifiers are an important means of regulating humidity and improving comfort in the home environment. Currently, commonly used types of humidifiers include ultrasonic, evaporative, and thermal mist types. Ultrasonic humidifiers may cause damage to the human respiratory tract due to their large atomized particles. Evaporative humidifiers, on the other hand, have a more uniform atomization effect and have gradually become one of the mainstream humidifier products.

[0055] Specifically, the power system and the humidifying filter are the two core components of an evaporative humidifier. With the advancement of materials technology, consumable-free humidifier cores made of rigid, non-absorbent materials such as plastics as the base material have begun to appear. This structure enables the wet curtain assembly to be regenerable without replacement and can be washed. Specifically, the humidifier core can be composed of multiple stacked curtain cores to facilitate the maintenance and replacement of individual curtain cores. However, when multiple independent curtain cores are stacked, there is a shaking problem, which affects the stability of the humidifier core.

[0056] In view of this, the present invention proposes a wet curtain assembly; please refer to [link / reference]. Figures 1 to 17 The following is an embodiment of the evaporative cooling pad assembly proposed in this application. The evaporative cooling pad assembly will be described in detail below with reference to the specific accompanying drawings.

[0057] Please see Figures 6 to 8The evaporative cooling pad assembly 100 includes a support frame 1, multiple curtain cores 2, and a water distribution tray 3. The multiple curtain cores 2 are installed on the support frame 1, and the material of the curtain cores 2 is water-resistant. The curtain cores 2 form an air outlet channel. The multiple curtain cores 2 are stacked, and each curtain core 2 is provided with a water passage hole 21 that runs vertically through it, so that humidifying water can flow from top to bottom through the multiple curtain cores 2. An air inlet channel 22 is formed at least partially between two adjacent curtain cores 2. The water distribution tray 3 is disposed above the multiple curtain cores 2 to carry the humidifying water, and the water distribution tray 3 is provided with a water distribution hole 31 to provide humidifying water to the multiple curtain cores 2. The water distribution tray 3 is connected to the top of the support frame 1, and the curtain core 2 located at the top abuts against the lower end face of the water distribution tray 3.

[0058] In the technical solution of this utility model, the wet curtain assembly 100 is one of the core components of the evaporative humidifier 1000. This embodiment mainly focuses on the structure of the wet curtain assembly 100 formed by stacking multiple curtain cores 2. The multiple curtain cores 2 are set independently, which facilitates the maintenance and replacement of individual curtain cores 2 and reduces the maintenance cost of the wet curtain assembly 100. The curtain cores 2 are made of water-resistant material and can be disassembled, washed, and reused, thereby achieving no consumable requirements. However, it is understood that the stacked structure of multiple curtain cores 2 may shake after stacking, resulting in an unstable overall structure. This will lead to uneven water distribution on the curtain cores 2, affecting the uniformity and efficiency of humidification of the humidifier 1000. Therefore, this application proposes that the water distribution plate 3 be connected to the top of the bracket 1 and then abut against the upper surface of the curtain core 2 located at the top. In this way, the water distribution plate 3 presses down on multiple curtain cores 2, thereby avoiding the problem of the structure of multiple stacked curtain cores 2 shaking, thereby improving the stability of the wet curtain assembly 100, improving the problem of uneven water distribution, effectively improving the humidification uniformity and humidification efficiency of the humidifier 1000, and meeting the functional requirements.

[0059] The evaporative humidifier 1000 mainly provides a sufficiently large water evaporation area through the wet curtain assembly 100. In this embodiment, multiple curtain cores 2 are stacked one on top of the other, and each curtain core 2 carries humidifying water to form a water film or even water accumulation, ensuring a sufficiently large evaporation area. Then, the air flowing in the air inlet duct 22 between adjacent curtain cores 2 carries away the humidifying water on the surface of the curtain core 2, thereby humidifying the ambient air. Based on this principle, it can be understood that the coverage of humidifying water on the curtain core 2 has a great impact on the humidification performance of the humidifier 1000. Therefore, this application provides corresponding improvement measures to address the situation described above where the shaking of the curtain core 2 affects the stability of the wet curtain assembly 100, and thus affects the coverage of humidifying water, thereby improving the humidification performance of the humidifier 1000.

[0060] It is understood that the curtain core 2 of the evaporative cooling pad assembly 100 can also be configured as an integral cylindrical structure, i.e., a cylindrical main body with multiple evaporation plates arranged around its periphery. These evaporation plates are used to receive the humidifying water flowing down from the water distribution plate 3 and form a water film on their surface. Simultaneously, the air inlet duct 22 is opened on the cylindrical main body. Airflow within the air inlet duct 22 removes moisture from the evaporation plates around the cylindrical main body, thus achieving the humidification function of the ambient air. This configuration avoids the swaying problem of the multiple stacked curtain cores 2 described above. However, it obviously cannot be specifically disassembled and maintained in a particular area, resulting in high maintenance costs. In this application, the multiple curtain cores 2 are independently configured, allowing for individual disassembly and maintenance, leading to low maintenance costs. Therefore, this application mainly uses multiple stacked curtain cores 2 to form the evaporative cooling pad assembly 100 and proposes a corresponding technical solution to solve the swaying problem of the multiple curtain cores 2, thereby meeting functional requirements.

[0061] Specifically, the contact form between the water distribution plate 3 and the curtain core 2 is not limited. As long as the water distribution plate 3, after installation, can press against multiple curtain cores 2, restricting their swaying, it is sufficient to meet the above requirements. In this embodiment, the top curtain core 2 and the water distribution plate 3 are connected by a first support structure. The first support structure includes a first support rib 23 and / or a second support rib 32. The first support rib 23 is located on the upper surface of the curtain core 2 and protrudes towards the water distribution plate 3; the second support rib 32 is located on the lower surface of the water distribution plate 3 and protrudes towards the curtain core 2. The first support rib 23 and the second support rib 32 can... One or both can be used. This embodiment uses both. Specifically, the relative arrangement of the first support rib 23 and the second support rib 32 creates an air duct between the curtain core 2 and the water distribution plate 3, ensuring that the upper surface of the curtain core 2 at the top is not blocked by the water distribution plate 3 and thus can perform evaporative humidification, guaranteeing humidification performance. Furthermore, it avoids uneven contact surfaces caused by the structural arrangement of the lower surface of the water distribution plate 3 and the upper surface of the curtain core 2, ensuring the stability of their contact. The structure of the first support rib 23 and the second support rib 32 is simple, easy to install, and low in cost. Of course, the first support structure can also be set to only the first support rib 23 or the second support rib 32, which can also satisfy the above functions. The specific arrangement depends on actual needs and is not limited here.

[0062] Furthermore, a water storage tank 25 is formed on the upper end face of the curtain core 2, and a plurality of water passage holes 21 are arranged at intervals on the tank wall of the water storage tank 25. The curtain core 2 can humidify the air only through the water film formed on its surface. That is, when the humidifying water flows from top to bottom through each curtain core 2, it only flows along the surface of the curtain core 2 and does not remain on the curtain core 2. The humidification needs are met by wetting the surface of the curtain core 2 to form a water film. This arrangement can reduce the possibility of humidifying water being contaminated due to retention. However, there may be a situation where the evaporation rate of the water film exceeds the rate at which the surface of the curtain core 2 is wetted by the humidifying water, affecting the humidification performance of the humidifier 1000. There may also be a situation where the humidifying water cannot flow evenly down the curtain core 2, affecting the uniformity of the humidifying water wetting of the curtain core 2, and thus affecting the uniformity of humidification of the humidifier 1000. Based on this, the present application forms a water storage tank 25 on the upper surface of the curtain core 2. On the one hand, the water storage tank 25 contains a certain amount of humidifying water, which can ensure that the airflow continuously carries away the water in the water storage tank 25, thereby ensuring the humidification performance of the humidifier 1000. On the other hand, the water passage hole 21 is provided on the wall of the water storage tank 25. That is, after a certain amount of humidifying water is accumulated in the water storage tank 25, it will flow to the lower curtain core 2 along the water passage hole 21. That is, after the humidifying water is evenly accumulated on each curtain core 2, it will flow to the lower curtain core 2, thereby ensuring that the water distribution of each curtain core 2 is uniform, thereby ensuring the humidification uniformity of the humidifier 1000 and meeting the functional requirements.

[0063] It is understandable that the longer the flow path of the humidifying water on the upper surface of the curtain core 2, the larger the area it contacts on the upper surface of the curtain core 2, and the longer the retention time, which can improve the evaporation area and evaporation performance of the curtain core 2. Therefore, in one embodiment of this application, the first support rib 23 includes a support piece disposed on the upper surface of the curtain core. The support piece extends along the width direction of the curtain core 2, thus partially blocking the flow of humidifying water along the circumference of the curtain core 2, so that the humidifying water needs to flow around the support piece, thereby extending the flow path of the humidifying water and meeting the above functional requirements. The curtain core 2 also has the above-mentioned... The support piece can be positioned between or corresponding to the two water passage holes 21. When positioned between the two water passage holes 21, it mainly blocks the flow of humidifying water along the circumference of the curtain core 2. When positioned corresponding to the water passage hole 21, it divides the water passage hole 21 into two parts, thereby diverting the humidifying water at the water passage hole 21 and ensuring uniform water flow at the water passage hole 21. Specifically, the position of the support piece is based on actual needs and is not limited here. Both positions can achieve the function of partially blocking the humidifying water and meet the functional requirements. It should be noted that the curtain core 2 can be a square structure, a circular structure, etc., arranged in a ring to form the air outlet channel. It is not limited here. In this application, the curtain core 2 is mainly set as a circular structure. Based on this, the width direction of the curtain core 2 is the radial direction of the circular curtain core 2.

[0064] In addition, in some other embodiments of this application, the first support rib 23 needs to avoid the water storage tank 25 to avoid affecting the flow of humidifying water in the water storage tank 25, thereby avoiding affecting the uniformity of water distribution in the water storage tank 25. Therefore, the first support rib 23 includes a first protruding rib close to the air outlet channel and a second protruding rib away from the air outlet channel. The first protruding rib, the second protruding rib, and the upper end face of the curtain core 2 surround the water storage tank 25, so that the first protruding rib and / or the second protruding rib form a water-blocking rib 26. The plurality of water passage holes 21 are arranged circumferentially along the air outlet channel. With this arrangement, the first protruding rib and the second protruding rib are arranged in a ring to form the water-blocking rib 26 of the water storage tank 25, so that the water storage tank 25 can perform water storage function. It will not only not block the flow of humidifying water, but also guide the humidifying water to flow along the water storage tank 25, thereby ensuring the uniformity of water distribution in the water storage tank 25 and meeting the usage requirements.

[0065] Furthermore, the water-blocking ribs 26 limit the water storage height within the water storage tank 25, thereby allowing the water storage tank 25 to store a larger amount of humidifying water. This increases the uniformity and consistency of water drainage within the curtain core 2, preventing only localized drainage. Additionally, the water-blocking ribs 26 are provided on the inner and outer sides of the water storage tank 25. When multiple curtain cores 2 are stacked, the water-blocking ribs 26 form the inner and outer appearance surfaces of the curtain cores 2, resulting in a better and more integrated appearance of the stacked curtain cores 2. Based on the first support rib 23 described above, which includes the first and second protruding ribs, the first and second protruding ribs can directly serve as the water-blocking ribs 26 of the water storage tank 25, or they can be set independently of the water-blocking ribs 26. In this embodiment, the first and second protruding ribs serve as the two water-blocking ribs 26 corresponding to the inner and outer sides of the water storage tank 25, simplifying the structure and reducing costs.

[0066] Furthermore, regarding the abutment support between adjacent curtain cores 2, in order to ensure the consistency of multiple curtain cores 2 and facilitate the installation of multiple curtain cores 2, each curtain core 2 is provided with a first support rib 23. The first support rib 23 includes a first protruding rib and a second protruding rib, and forms the water-blocking rib 26 as described above. In order to avoid it blocking the air intake channel between two adjacent curtain cores 2 as the water-blocking rib 26, when the first support rib 23 is used as a support structure between two adjacent curtain cores 2, the first support rib 23 can be set to also include a first support part 231 protruding upward from the water-blocking rib 26. In this way, the curtain core 2 above it is supported by the first support part 231. Based on the structure of the first support part 231, the first support part 231 can directly support the lower end face of the curtain core 2 above it, and also allow the lower end face of the curtain core 2 above it to form the air intake channel with the water-blocking rib 26 at intervals, thus meeting the structural requirements. Of course, besides setting the first support portion 231 on the water-blocking rib 26, a second support portion 24 can also be set on the lower end face of the curtain core 2. The second support portion 24 abuts against the first support rib 23, thus supporting adjacent curtain cores 2. Simultaneously, the lower end face of the upper curtain core 2 and the water-blocking rib 26 are spaced apart to form the air inlet duct, which also meets structural requirements. Therefore, the first support portion 231 and the second support portion 24, as described above, can meet structural functional requirements if set independently. In this embodiment, the first support portion 231 and the second support portion 24 are set simultaneously, and they are aligned vertically. Thus, given the vertical dimension requirements of the air inlet duct 22, the aligned combination of the first support portion 231 and the second support portion 24 is obviously smaller in the vertical direction than when either the first support portion 231 or the second support portion 24 is used alone. This ensures the structural strength of the first support portion 231 and the second support portion 24. Based on this, it is also possible to omit the first support rib 23 as the support structure between two adjacent curtain cores 2 and set up a separate support structure, but obviously the cost is high and it is not practical. Setting the first support rib 23 to be used to support both the curtain core 2 and the water distribution plate 3 is a clever structure with low cost.

[0067] It should be noted that setting the first support rib 23 as a combination of the water-blocking rib 26 and the first support part 231 does not affect the abutment support between the first support rib 23 and the second support rib 32 on the water distribution plate 3. On the contrary, in this embodiment, the second support rib 32 is set opposite to the first support part 231, thereby ensuring the spacing between the upper end face of the curtain core 2 at the top and the lower end face of the water distribution plate 3, ensuring the ventilation size, and thus ensuring the humidification performance of the curtain core 2 at the top.

[0068] Furthermore, the water storage tank 25 can be formed by the water-blocking rib 26 described above and the upper end face of the curtain core 2. In other embodiments, the upper end face of the curtain core 2 can be set as a groove structure, that is, the water storage tank 25 includes a first groove wall and a second groove wall, the upper ends of the first groove wall and the second groove wall extend in a direction away from each other, the water passage hole 21 is provided in the first groove wall and / or the second groove wall, and the first support rib 23 is provided at the end of the first groove wall and the second groove wall that are away from each other. In this way, the water storage tank 25 is formed by the inclined first groove wall and the second groove wall. Of course, the first support rib 23 here can still be set to include the water-blocking rib 26 to further increase the water storage capacity of the water storage tank 24.

[0069] Furthermore, the water passage hole 21 can be located on the first tank wall, the second tank wall, or both the first and second tank walls. This is not a limitation. In this embodiment, the lower ends of the first and second tank walls are connected to each other, and the water passage hole 21 is located at the connection between the first and second tank walls, i.e., at the bottom of the water storage tank, to facilitate water passage. Furthermore, to ensure the humidification performance of the curtain core 2, the water storage tank 25 needs to accumulate humidification water. This ensures both uniform flow of humidification water and the accumulation of humidification water for evaporation within the water storage tank 25. A protrusion is provided around the water passage hole 21, and the height of the protrusion is set less than the height of the first and second tank walls to meet the requirements for humidification water accumulation and flow, thus ensuring the humidification performance of the wet curtain assembly 100.

[0070] Furthermore, as described above, the adjacent curtain cores 2 are spaced apart in the vertical direction. It is understood that when the humidifying water flowing down from the upper curtain core 2 falls directly into the water storage tank 25 of the lower curtain core 2, there may be splashing noise, and the humidifying water in the water storage tank 25 may be splashed, affecting the user experience of the humidifier 1000. Therefore, in some embodiments of this application, the lower end face of the curtain core 2 is provided with multiple wet curtain sheets 27, and the wet curtain sheets 27 are corresponding to... The water passage 21 is designed so that the humidifying water flowing down through the water passage 21 will flow down along the outer wall of the wet curtain 27 without splashing as mentioned above. The humidifying water flows over the outer wall of the wet curtain 27, forming a water film on the outer wall of the wet curtain 27. At the same time, the wet curtain 27 is located in the air inlet duct 22. Compared with the humidifying water in the water storage tank 25, the water film on the wet curtain 27 is obviously more easily carried away by the airflow, thereby improving the humidification performance of the humidifier 1000.

[0071] Regarding the arrangement of the evaporative cooling pad 27 on the curtain core, considering that the evaporative cooling pad 27 is mainly used to guide the humidifying water flowing down from the water passage 21 of the second curtain core 2b, and at the same time it is necessary to avoid obstructing the water flow path in the water storage tank 25, in this embodiment the evaporative cooling pad 27 is set on the lower end face of the curtain core corresponding to the position of the water passage 21, and there is a gap between the bottom end of the evaporative cooling pad 27 and the upper end face of the curtain core, that is, the evaporative cooling pad 27 avoids the water storage tank 25 on the curtain core 2, thereby meeting the functional requirements.

[0072] Furthermore, the bracket 1 is used to support multiple curtain cores 2 and restrict the movement of the curtain cores 2 in the width direction of the multiple curtain cores 2, so that the multiple curtain cores 2 are stacked to form a cylindrical structure, as described above. In this embodiment, the bracket 1 includes a base 12 located at the bottom and a limiting frame 11 disposed around the base 12. The base 12 has a drain outlet 121. The multiple curtain cores 2 are clamped and fixed by the base 12 and the water distribution plate 3 to achieve the function of stabilizing the curtain cores 2 required by this application. The limiting frame 11 is located around the multiple curtain cores 2 to limit the movement of the multiple curtain cores 2 in the width direction. Considering that the adjacent curtain cores 2 are spaced apart by the air inlet ducts 22, the limiting frame 11 needs to avoid obstructing the air inlet ducts 22 as much as possible to ensure the air inlet area of ​​the air inlet ducts 22, thereby ensuring the humidification efficiency of the humidifier 1000. Based on this, this application aligns the first support parts 231 and the second support parts 24 on the multiple curtain cores 2 in the vertical direction. Since the first support parts 231 and the second support parts 24 will also obstruct the air inlet ducts 22 when they abut against each other, the first support parts 231 and the second support parts 24 are positioned vertically. The support 24 is aligned vertically, and the limiting frame 11 is configured as a plurality of vertically extending limiting posts. The limiting posts are set corresponding to the first support 231 and the second support 24, so that the limiting posts are arranged opposite to the first support 231 and the second support 24 in the width direction of the curtain core 2. In this way, while the first support 231 and the second support 24 block the air inlet duct 22, the limiting posts no longer block the air inlet duct 22, thereby ensuring the air inlet area of ​​the air inlet duct 22. The structure is ingenious and the effect is good.

[0073] Furthermore, in this embodiment, a second support structure is provided between the base 12 and the curtain core located at the bottom, so that there is a gap between the water passage hole 21 of the curtain core 2 located at the bottom and the base 12. Specifically, the second support structure includes the second support part 24 located at the bottom of the curtain core 2, and also includes a support member 122 located on the upper end face of the base 12. As for the support member 122 provided on the base 12, it can be understood that the base 12 in this application is set as a water receiving tray, that is, the water receiving tray receives the humidifying water flowing through multiple curtain cores 2. The support member 122 is provided on the one hand to support and fix multiple curtain cores 2, and on the other hand to create an air duct between the water receiving tray and the curtain core 2, so as to maximize the humidification efficiency of the humidifier 1000.

[0074] In the technical solution of this utility model, the material of the curtain core 2 is a hydrophobic material, which can be set as plastic or metal or other hard, water-resistant materials, so that each of the curtain cores 2 can be rinsed and cleaned after being removed, and is not easily damaged, thus meeting the consumable-free performance of the humidifier 1000.

[0075] Please see Figures 1 to 5 This utility model also proposes a humidifier 1000, which includes a housing 200, a wet curtain assembly 100, a water tank 300, and a fan assembly 500.

[0076] The evaporative humidifier 1000 proposed in this application specifically includes the evaporative cooling pad assembly 100, the water tank 300, and the fan assembly 500. The fan assembly 500 is positioned above the cylindrical evaporative cooling pad assembly 100, driving air from the outer periphery of the evaporative cooling pad assembly 100 through the air inlet duct 22 into the inner side of the evaporative cooling pad assembly 100, thus removing moisture from the evaporative cooling pad assembly 100. The fan assembly 500 then drives the humidified air back into the external environment, achieving the air humidification function. The water tank 300 is located below the evaporative cooling pad assembly 100, serving to receive the humidifying water flowing down from the evaporative cooling pad assembly 100. The water tank 300, through the water delivery assembly 400, transports the humidifying water in the water tank 300 to the water distribution plate 3 at the upper end of the evaporative cooling pad assembly 100, thereby ensuring the circulation of the humidifying water on the evaporative cooling pad assembly 100. The housing 200 is an exterior component, which is fitted onto the wet curtain assembly 100, the water tank 300, and the fan assembly 500. Its main purpose is to isolate the wet curtain assembly 100 from the external environment, on the one hand to prevent the humidifying water on the wet curtain assembly 100 from being contaminated, and on the other hand to prevent the possibility of humidifying water splashing out.
