Description

Technical Field

[0001] This invention relates to the field of humidifier technology, and in particular to a wet curtain assembly and a humidifier. Background Technology

[0002] Humidifiers are an important means of regulating humidity and improving comfort in the home environment. Among them, the power system and the humidifying filter are the two core components of an evaporative humidifier. However, the main body of the wet curtain in existing humidifying filters is usually formed by stacking multiple curtain cores.

[0015] The evaporative cooling pad assembly also includes:

[0016] A bracket, wherein the at least two curtain cores are disposed within the bracket;

[0017] A water distribution box is located at the upper end of the bracket; and,

[0018] A water pipe, with its two ends respectively located at the bracket and the water distribution box, is used to supply water to the water distribution box.

[0019] In one embodiment, two support portions are provided, and the two support portions are spaced apart along the width direction of the curtain core; and / or,

[0020] Multiple support portions are provided, and the multiple support portions are spaced apart along the circumference of the curtain core.

[0021] In one embodiment, the curtain core is made of a hydrophobic material; and / or,

[0022] The material of the curtain core can be plastic or metal.

[0023] The present invention also provides a wet curtain assembly, comprising:

[0024] Multiple curtain cores, the curtain cores being made of water-resistant material, are stacked one on top of the other, with an opening in the middle of each curtain core to define an air passage extending vertically, and air passage holes connecting the air passages are formed between adjacent curtain cores, and each curtain core is provided with a flow hole so that humidifying water can flow from top to bottom through the multiple curtain cores.

[0025] The lower end of the curtain core is provided with a water distribution component to guide humidifying water into the curtain core below.

[0026] In one embodiment, the water distribution element is provided corresponding to the flow passage; and / or,

[0027] The water distribution component includes a plurality of water distribution plates extending along the width direction of the curtain core, and the plurality of water distribution plates are spaced apart along the width direction of the curtain core.

[0028] In one embodiment, the flow holes and the water distribution components are configured as water distribution groups, and multiple water distribution groups are arranged at intervals along the circumference of the curtain core.

[0029] In addition, the present invention also provides a humidifier, comprising:

[0030] The housing has an air inlet, an air outlet, and a ventilation channel connecting the air inlet and the air outlet;

[0031] The evaporative cooling pad assembly is installed within the ventilation duct;

[0032] A water tank is disposed inside the housing and located below the wet curtain assembly. The water tank is used to guide water to the upper end of the wet curtain assembly through the water conveying assembly, and the water tank is used to receive water flowing down through the wet curtain assembly.

[0033] A fan assembly is disposed within the ventilation channel and located above the wet curtain assembly. The fan assembly is used to drive airflow from the air inlet to the air outlet.

[0034] The wet curtain assembly includes at least two curtain cores stacked vertically. The curtain cores are made of a water-resistant material. Each curtain core has an opening in the middle to define an air passage extending vertically. Multiple air passage holes are formed between adjacent curtain cores to connect the air passage. The at least two curtain cores include a first curtain core and a second curtain core.

[0036] In the technical solution of this invention, by providing the air passage and the plurality of air holes, airflow can flow in from the side of the curtain core and then out from the center of the curtain core. By providing the first water flow channel and the second water flow channel, water can flow circumferentially along the curtain core. By providing the first flow hole and the second flow hole, water can flow downward under the action of gravity, allowing the water flow to interact with the airflow to humidify the gas flowing into the wet curtain body. At the same time, the first flow hole and the second flow hole at least partially... The staggered arrangement of the curtain cores allows the lower curtain core to block the water flow, preventing it from passing directly through. This allows the water to diffuse along the surface of the curtain core, wetting the entire core before flowing to the next layer. This increases the water flow distance, expands the contact area between the water and airflow, and extends the residence time of the water on the curtain core, allowing the airflow to carry more moisture. This improves the humidification effect of the wet curtain assembly and solves the problem of insufficient water wetting of the curtain core by the humidifying filter. Attached Figure Description

[0057] Humidifiers are an important means of regulating humidity and improving comfort in the home environment. Among them, mist-free humidifiers are a new type of humidifier that achieves humidification by blowing water from a humidifying curtain into the external environment. The humidifier uses a water pump to draw water from the tank to the top of the humidifying curtain for spraying. When the humidifying curtain or filter is saturated, excess water flows back to the bottom tank and is then pumped back to humidify the curtain. The power system and the humidifying filter are the two core components of an evaporative humidifier. However, the humidifying curtain in existing humidifying filters is usually formed by stacking multiple curtain cores. Each curtain core has flow holes to allow water to spray multiple cores sequentially under gravity. But if the flow holes of each curtain core are aligned, the water may pass directly through the lower curtain core, preventing the water from flowing circumferentially and thus failing to adequately wet the lower curtain core, affecting the humidifying effect of the humidifying filter.

[0058] Analysis of the causes of the above problems reveals that the water flow in the existing humidifying filter cartridge may not flow circumferentially along the curtain core when flowing downwards, resulting in insufficient water wetting of the curtain core and thus affecting the humidification effect of the humidifying filter cartridge. To solve the problem of insufficient water wetting of the curtain core, the structure of the humidifying filter cartridge can be improved by staggering the flow holes of two adjacent curtain cores to prevent the water flow from directly passing through the lower curtain core, thus ensuring that the water flow can fully wet the curtain core.

[0059] Based on this, the present invention proposes a wet curtain assembly for a humidifier, aiming to solve the problem that the water flow in existing humidifier filters fails to adequately wet the curtain core. Among other things, Figures 1 to 9This is a schematic diagram of the structure of the wet curtain assembly provided by the present invention; Figures 10 to 12 This is a schematic diagram of the humidifier provided by the present invention.

[0060] Please see Figures 1 to 4 In one embodiment of the present invention, the wet curtain assembly 100 includes at least two curtain cores 1 stacked vertically. The curtain cores 1 are made of a water-resistant material. Each curtain core 1 has an opening in the middle to define an air passage 12. A plurality of air passage holes communicating with the air passage 12 are formed between adjacent curtain cores 1. The at least two curtain cores 1 include a first curtain core 1a and a second curtain core 1b. A first water flow channel extending circumferentially is formed on the upper surface of the first curtain core 1a. The first water flow channel is provided with a first flow hole 13a. A second water flow channel extending circumferentially is formed on the upper surface of the second curtain core 1b. The second water flow channel is provided with a second flow hole 13b. The first flow hole 13a and the second flow hole 13b are at least partially misaligned.

[0061] It should be noted that the shapes of the first flow-through hole 13a and the second flow-through hole 13b are varied, including circular, rectangular, and rhomboid shapes, etc., and this invention does not limit them. Furthermore, the apertures of the first flow-through hole 13a and the second flow-through hole 13b are varied, including equal diameter and variable diameter, etc., and this invention does not limit them. The air passage is mainly used to allow gas to flow in from the side of the wet curtain body 1 and collect radially along the wet curtain body 1 into the air passage 12. Its shape is varied, including circular and polygonal shapes, etc., and this invention does not limit it. Similarly, the air passage 12 is mainly used to allow gas to flow out axially along the wet curtain body 1. Its shape is varied, including circular and polygonal shapes, etc., and this invention does not limit it. In addition, the at least two curtain cores 1 are varied; please refer to [reference needed]. Figure 5 and Figure 6 The at least two curtain cores 1 can be two first curtain cores 1a, two second curtain cores 1b, or one first curtain core 1a and one second curtain core 1b. The present invention does not limit this.

[0062] It should also be noted that the at least partial misalignment of the first flow-through hole 13a and the second flow-through hole 13b means that the first flow-through hole 13a and the second flow-through hole 13b can be partially misaligned or completely misaligned. Of course, when there are multiple first flow-through holes 13a and second flow-through holes 13b, only a portion of the multiple holes can be misaligned or all of them can be misaligned, etc., and this invention does not limit this. Furthermore, the arrangement of the first flow-through hole 13a and the second flow-through hole 13b can be the same, for example, both the first flow-through hole 13a and the second flow-through hole 13b can be located in the middle of the curtain core 1, or they can be different, for example, the first flow-through hole 13a can be located in the middle of the curtain core 1, and the second flow-through hole 13b can be located at the edge of the curtain core 1, and this invention does not limit this.

[0063] It should be noted that since the absorbent substrate is typically made of materials such as spunlace fabric, 3D fiber fabric, or corrugated paper, it will suffer material damage after a certain period of use and therefore needs to be replaced regularly. Therefore, the material of the curtain core 1 is a water-resistant material. Water-resistant materials can be repeatedly washed and maintain physical / chemical stability under conditions such as soaking, rubbing, and washing. Combined with the material's water resistance, abrasion resistance, and chemical resistance, it has a longer lifespan, allowing the wet curtain to achieve a consumable-free effect during its service life. Furthermore, due to process limitations, it is difficult to make different sizes of air inlets when processing materials such as spunlace fabric, 3D fiber fabric, and corrugated paper. The material selection of this invention not only solves the problem of replacing and maintaining the absorbent substrate but also allows for shaping and processing according to design requirements. In this embodiment, the material of the curtain core 1 is a hydrophobic material, specifically, it can be plastic, metal such as aluminum alloy, or other rigid materials, so that each curtain core 1 can be removed for rinsing and cleaning.

[0064] In the technical solution of this invention, by setting the air passage 12 and the plurality of air holes, airflow can flow in from the side of the curtain core 1 and then flow out from the center of the curtain core 1. By setting the first water flow channel and the second water flow channel, water can flow around the circumference of the curtain core 1. By setting the first flow hole 13a and the second flow hole 13b, the water in the first water flow channel and the second water flow channel can flow downward under the action of gravity, so that the water flow can interact with the airflow to humidify the incoming air. At the same time, the first flow hole 13a and the second flow hole 13b... The flow holes 13b are at least partially offset, allowing the lower curtain core 1 to block the water flow and prevent it from passing directly through the curtain core 1. This allows the water flow to diffuse along the upper surface of the curtain core 1, enabling it to wet the entire curtain core 1 before flowing to the next layer of curtain core 1. This increases the flow distance of the water flow, improves the contact range between the water flow and the air flow, and increases the residence time of the water flow on the curtain core 1, further increasing the contact time between the water flow and the air flow. This allows the air flow to carry more moisture, which is beneficial for improving the humidification effect of the wet curtain assembly 100. This solves the problem that the water flow of the humidifying filter cartridge cannot fully wet the curtain core 1.

[0065] Furthermore, there are various ways in which the first flow passage 13a and the second flow passage 13b are staggered. In one embodiment, please refer to... Figure 3 and Figure 4 In the circumferential direction of the curtain core 1, the first flow hole 13a and the second flow hole 13b are staggered, so that the humidifying water in the first water flow channel flows into the second water flow channel through the first flow hole 13a, and is diverted to the second flow hole 13b on both sides of the circumferential direction of the curtain core 1. Thus, by staggering the first flow hole 13a and the second flow hole 13b circumferentially, water flow is prevented from directly passing through the lower curtain core 1, allowing water flow on the lower curtain core 1 to be diverted to the second flow hole 13b on both sides of the circumferential direction of the curtain core 1, enabling the water flow to wet the entire curtain core 1, thereby improving the humidification effect of the wet curtain assembly 100. It should be noted that the flow holes 13 on the two curtain cores 1 can be arranged as follows: Figure 3 The two first flow holes 13a shown can also be as follows: Figure 4 The two second flow holes 13b shown can also be as follows: Figure 2 The invention shows a first flow passage 13a and a second flow passage 13b, but does not limit the scope of the invention.

[0066] In another embodiment, please refer to Figure 2In the width direction of the curtain core 1, the first flow hole 13a and the second flow hole 13b are staggered so that the humidifying water in the first water flow channel flows into the second water flow channel through the first flow hole 3a and is diverted to the second flow hole 13b on both sides of the width direction of the curtain core 1. In this way, by staggering the first flow hole 13a and the second flow hole 13b along their width direction, the flow holes 112 of the upper curtain core 1 and the flow holes 112 of the lower curtain core 1 are staggered, preventing water from directly passing through the lower curtain core 1. This allows the water on the lower curtain core 1 to flow along the width direction of the curtain core 1, so that the water can wet the entire curtain core 1, thereby helping to improve the humidification effect of the wet curtain assembly 100. It is understood that when the first flow-through hole 13a is located at the center of the curtain core 1, the second flow-through hole 13b is located at the edge of the curtain core, so that the first flow-through hole 13a and the second flow-through hole 13b are offset in the width direction of the curtain core 1, allowing water flow on the lower part of the curtain core 1 to flow from the edge to the center along its width direction. Conversely, when the first flow-through hole 13a is located at the edge of the curtain core 1, the second flow-through hole 13b is located at the center of the curtain core 1, so that the first flow-through hole 13a and the second flow-through hole 13b are offset in the width direction of the curtain core 1, allowing water flow on the lower part of the curtain core 1 to flow from the center to the edge along its width direction. Further, the width of the curtain core 1 refers to the distance between the inner and outer peripheries of the curtain core 1.

[0067] It should be noted that the above two related technical features, "the flow holes 112 of two adjacent curtain cores 1 are staggered in the circumferential direction of the curtain core 1" and "the flow holes 112 of two adjacent curtain cores 1 are staggered in the width direction of the curtain core 1", can be set either one or both. The present invention does not limit this. Obviously, setting both at the same time is better.

[0068] The number of flow holes on the curtain core 1 can vary, including one or more, and this invention does not limit this. Specifically, in this embodiment, the first flow hole 13a and the second flow hole 13b are configured as flow holes 13, and multiple flow holes 13 are provided. These multiple flow holes 13 are spaced apart along the circumference of the curtain core 1. By providing multiple flow holes 112, on the one hand, the water-passing area of ​​the curtain core 1 can be increased, allowing water to flow quickly into the lower curtain core 1 to prevent overflow. On the other hand, it allows water to flow evenly along the circumference of the upper curtain core 1, which not only allows the water to spread evenly on the lower curtain core 1 but also increases the diffusion rate of the water, enabling the water to quickly cover the entire curtain core 1.

[0069] The at least two curtain cores 1 can be varied; for example, they can be two first curtain cores 1a. Please refer to [link / reference]. Figure 3 and Figure 5 The at least two curtain cores 1 can also be two second curtain cores 1b, please refer to [link / reference]. Figure 4 and Figure 6 This invention does not limit the scope of the invention. Specifically, in this embodiment, please refer to... Figure 3 and Figure 4 Along the circumference of the curtain core 1, the projection of the first flow hole 13a onto the second curtain core 1b is located in the middle of the two second flow holes 13b, so that the flow holes 13 of the upper curtain core 1 are offset from the flow holes 13 of the lower curtain core 1, so that the lower curtain core 1 can block the water flow left above, so as to prevent the water flow from flowing into the next layer of curtain core 1 before it has spread, so that the water flow on the lower curtain core 1 can be diverted and diffused to both sides of the circumference of the curtain core 1, so that the water flow can wet the entire curtain core 1 before flowing into the next layer of curtain core 1. Furthermore, along the circumference of the curtain core 1, the length between two adjacent flow holes 13 of the curtain core 1 of different layers is b3, and the length between two adjacent flow holes 13 of the curtain core 1 of the same layer is b4, wherein 0 < b3 / b4 < 1, preferably b3 / b4 = 0.5. In this way, the upper flow hole 13 is located in the middle of the lower flow hole 13, so that the water flow can be evenly distributed to both sides of the curtain core 1 in the circumference direction.

[0070] It should be noted that there are multiple ways to arrange the flow holes 13 of the two curtain cores 1. In one embodiment, please refer to [reference needed]. Figure 6 Both of the curtain cores 1 are provided with a set of flow-through groups, and each flow-through group includes a plurality of flow-through holes 13 spaced apart along the circumference of the curtain core 1. In another embodiment, please refer to Figure 5 Each of the two curtain cores 1 is provided with two sets of flow groups, and each flow group includes a plurality of flow holes 13 spaced apart along the circumference of the curtain core 1.

[0071] Furthermore, the two curtain cores 1 may be arranged identically or differently; the present invention does not limit this. Specifically, in this embodiment, please refer to... Figure 2Multiple first flow holes 13a form at least one first flow group, which includes multiple first flow holes 13 distributed circumferentially along the core 1. Multiple second flow holes 13b form multiple second flow groups, which are distributed along the width direction of the core 1. Each second flow group includes multiple second flow holes 13b distributed circumferentially along the core 1. Thus, the flow holes 13 on the two cores 1 are arranged differently to stagger the flow holes 13 of the upper core 1 and the lower core 1. The lower core 1 can block the water flowing down from above, preventing the water from flowing into the next core 1 before it has spread. This allows the water on the lower core 1 to be diverted and diffused to both sides of the width direction of the core 1, so that the water can wet the entire core 1 before flowing into the next core 1. Further, please refer to... Figure 2 Along the width direction of the curtain core 1, the length between two adjacent flow holes 13 of the curtain core 1 of different layers is b1, and the length between two adjacent flow holes 13 of the curtain core 1 of the same layer is b2, wherein 0 < b1 / b2 < 1, preferably b1 / b2 = 0.5. In this way, the upper flow hole 13 is located in the middle of the lower flow hole 13, so that the water flow can be evenly distributed and diffused on both sides along the width direction of the connecting core 1.

[0072] It should be noted that there are multiple ways to arrange the first curtain core 1a and the second curtain core 1b. For example, the first curtain core 1a can be positioned above the second curtain core 1b. Specifically, as shown below... Figure 2 As shown, the second curtain core 1b can also be positioned above the first curtain core 1a, but the present invention does not limit this.

[0073] Furthermore, the first flow-through group is positioned in the area between the two second flow-through groups. This allows the flow-through holes 13 of the first flow-through group to be offset from the flow-through holes of the second flow-through groups in the width direction of the curtain core 1. This enables the lower curtain core 1 to block the water flowing down from above, preventing the water from rapidly flowing into the next layer of curtain core 1 before it has had a chance to spread. Instead, the water on the lower curtain core 1 can be diverted and diffused to both sides in the width direction of the curtain core 1, allowing the water to wet the entire curtain core 1 before flowing into the next layer. Of course, in other embodiments, the first flow-through group can also be positioned in an area outside the two second flow-through groups; this invention does not limit this.

[0074] In one embodiment of the present invention, please refer to Figures 7 to 9The first flow-through hole 13a and the second flow-through hole 13b are configured as flow-through holes 13. A water-dividing component 14 is provided at the lower end of the curtain core 1, corresponding to the flow-through hole 13. By providing the water-dividing component 14, water flowing into the flow-through hole 13 can flow downwards along both sides of the water-dividing component into the next layer of curtain core 1. This increases the evaporation area of ​​the water flow, improving the humidification effect, and guides the water flow downwards into the next layer of curtain core 1, reducing water flow noise and thus improving the user experience of the wet curtain assembly 100. Furthermore, a water storage tank 15 is provided on the upper surface of the curtain core 1 to store a certain amount of water, allowing the water flow to diffuse circumferentially along the curtain core 1, thereby helping to wet the entire curtain core 1.

[0075] It should be noted that there are various molding methods for the water distribution component 14 and the curtain core 1. The water distribution component 14 and the curtain core 1 can be integrally molded or separately molded, and the present invention does not limit this. Specifically, the curtain core 1 and the water distribution component 14 are integrally molded to eliminate the assembly process and improve the assembly efficiency of the wet curtain assembly 100.

[0076] To facilitate water flow along the circumference of the curtain core 1, in this embodiment, please refer to... Figures 7 to 9 The lower end of the curtain core 1 is provided with a support part 2, which supports the lower curtain core 1 and spacees the water-dividing component 14 from the lower curtain core 1. Thus, by providing the support part 2, the upper curtain core 1 can be supported on the lower curtain core 1, allowing adjacent curtain cores 1 to be stacked together vertically. It also creates a gap between the water-dividing component 14 and the lower curtain core 1, preventing the water-dividing component 14 from obstructing the water flow on the lower curtain core 1 and facilitating the circumferential diffusion of water along the curtain core 1, thereby promoting water wetting of the entire curtain core 1. Specifically, to create a gap between the lower end of the water-dividing component 14 and the curtain core 1, the height of the support part 2 needs to be greater than the height of the water-dividing component 14. However, this arrangement results in a larger distance between adjacent curtain cores 1. Therefore, in this embodiment, please refer to... Figure 9The support part 2 has a vertical dimension of a1, the side end of the curtain core 1 has a vertical dimension of a2, and the water distribution component 14 has a vertical dimension of a3, where a1 + a2 > a3. Since the upper end of the curtain core 1 is provided with the water storage tank 15, the lower end of the water distribution component 14 only needs to leave a gap with the bottom of the water storage tank 15. Therefore, a1 + a2 > a3, so as to reuse the depth of the water storage tank 15. This allows a gap to be formed between the lower end of the water distribution component 14 and the bottom of the water storage tank 15 to avoid obstructing the water flow on the curtain core 1, and also reduces the height of the water distribution component 14, which helps to reduce the distance between two adjacent curtain cores 1, thereby helping to reduce the overall size of the wet curtain assembly 100.

[0077] It should be noted that the support part 2 can be of various types, such as a support plate or a support rib, and the present invention does not limit this. Furthermore, the forming method between the support part 2 and the curtain core 1 can be varied; the support part 2 and the curtain core 1 can be integrally formed or separately formed, and the present invention does not limit this. Specifically, the curtain core 1 and the support part 2 are integrally formed to eliminate the assembly process and improve the assembly efficiency of the wet curtain assembly 100. In addition, there are various ways to stack two curtain cores 1. In other embodiments, the wet curtain assembly 100 also includes a bracket 3 extending vertically, with both curtain cores 1 disposed within the bracket 3, so that the upper curtain core 1 can be suspended above the lower curtain core 1. Thus, by setting the bracket 3, multiple curtain cores 1 can be stacked together.

[0078] Furthermore, two support portions 2 are provided, spaced apart along the width direction of the curtain core 1. Thus, by providing two support portions 2, both the inner and outer sides of the curtain core 1 can be supported simultaneously, thereby improving the stability of the wet curtain body 1. It is understood that the width of the curtain core 1 refers to the distance between the inner and outer perimeters of the curtain core 1.

[0079] In some embodiments, multiple support portions 2 are provided, and the multiple support portions 2 are arranged at intervals along the circumference of the curtain core 1. In this way, by providing multiple support portions 2, on the one hand, the upper curtain core 1 can be supported at different positions of the lower curtain core 1 at the same time, thereby improving the stability of the wet curtain body 1. On the other hand, a large gap is left between two support portions 2 to avoid obstructing the gas flow, so that the gas can flow along the side of the curtain core 1 into the air passage 12 in the middle.

[0080] It should be noted that the above two related technical features, "two support parts 2 are provided, and the two support parts 2 are spaced apart along the width of the curtain core 1" and "multiple support parts 2 are provided, and multiple support parts 2 are spaced apart along the circumferential direction of the curtain core 1", can be provided selectively or simultaneously, and the present invention does not limit this.

[0081] In one embodiment of the present invention, please refer to Figure 8 and Figure 9 Multiple water-dividing components 14 are arranged at intervals along the circumference of the curtain core 1 and are respectively provided for multiple flow holes 13. Each water-dividing component 14 includes two water-dividing plates arranged at intervals along the width direction of the curtain core 1. Thus, multiple water-dividing plates are arranged along the circumference of the curtain core 1 and form a two-ring arrangement. There is a certain interval between the two water-dividing plates in each water-dividing component 14 to form a channel for water flow, so as not to obstruct the water flow on the lower curtain core, thereby facilitating the diffusion of water flow on the lower curtain core 1.

[0082] Further, in one embodiment, please refer to Figure 5 The at least two curtain cores 1 include a first curtain core 1a. The water storage tank 15 of the first curtain core 1a has multiple first flow holes 13a on its two opposite sidewalls in the width direction. Two water-dividing plates in each of the water-dividing components 14 correspond to the two opposite first flow holes 13a in the width direction of the water storage tank 15. Thus, the water flowing out of each flow hole 112 can fall onto the corresponding water-dividing plate, thereby being guided by the water-dividing plate. That is, the downward projection of each flow hole 112 can fall onto the corresponding water-dividing plate. It should be understood that when the sidewall of the water storage tank 15 is inclined, the water-dividing plate 14 is also inclined, with the inclination angle consistent with the sidewall of the water storage tank 15. In this case, the straight lines containing the two water-dividing plates in each water-dividing component 14 are set at an angle.

[0083] In one embodiment of the present invention, please refer to Figure 1 The wet curtain assembly 100 further includes a bracket 3, a water distribution box 4, and a water pipe 5. The curtain core 1 is disposed inside the bracket 3, the water distribution box 4 is disposed at the upper end of the bracket 3, and the two ends of the water pipe 5 are respectively disposed at the bracket 3 and the water distribution box 4 for supplying water to the water distribution box 4. Thus, by setting the bracket 3, the curtain core 1 can be installed, and by setting the water distribution box 4, humidifying water can be supplied to the curtain core 1. By setting the water pipe 5, water can be supplied to the water distribution box 4, and the water pipe 5 can cooperate with the water distribution box 4 to fix the wet curtain body 1 inside the bracket 3.

[0084] Furthermore, the support 3 includes a base 31 and a wet curtain frame 32. At least two curtain cores 1 are disposed on the upper end of the base 31 and within the wet curtain frame 32. Thus, by setting the base 31 to cooperate with the water distribution box 4, the vertical movement of the curtain cores 1 is restricted. By setting the wet curtain frame 32, both horizontal movement of the curtain cores 1 and horizontal support are restricted, allowing multiple curtain cores 1 to be stacked together. Furthermore, the base 31 and the wet curtain frame 32 can be integrally formed or separately formed. Specifically, in this embodiment, the base 31 and the wet curtain frame 32 are integrally formed to eliminate the assembly process.

[0085] The present invention also proposes a wet curtain assembly 100, wherein the wet curtain assembly includes a plurality of curtain cores 1, the curtain cores 1 being made of a water-resistant material, the plurality of curtain cores 1 being stacked vertically, the plurality of curtain cores 1 having an opening in the middle to define an air passage 12 extending vertically, air passage holes forming between adjacent curtain cores 1 communicating with the air passage 12, and each curtain core 11 having a flow hole 13 to allow humidifying water to flow from top to bottom through the plurality of curtain cores 1, wherein the lower end of each curtain core 1 is provided with a water divider 14 to guide humidifying water into the curtain core 1 below. Thus, by setting the water divider 14, on the one hand, the evaporation area of ​​the water flow can be increased, which helps to improve the humidification effect; on the other hand, the water flow can be guided downward into the next layer of curtain core 1, reducing the flow noise of the water flow, thereby helping to improve the user experience of the wet curtain assembly 100.

[0086] Please see Figure 5 and Figure 6 In this embodiment, the water distribution component 14 is arranged corresponding to the flow hole 13, so that the flow hole 13 is directly opposite the flow hole 13. This allows the water distribution component 14 to evenly divide the flow hole 13, ensuring that the water flowing into the flow hole 13 is evenly distributed on both sides of the water distribution component 14, thus uniformly wetting both sides of the water distribution component 14 and improving the humidification effect of the wet curtain assembly 100. Furthermore, the water distribution component 14 can be arranged in various ways; in other embodiments, it can also be positioned offset from the flow hole 13. This invention does not limit this arrangement.

[0087] In one embodiment of the present invention, the water distribution component 14 includes a plurality of water distribution plates extending along the width direction of the curtain core 1. The plurality of water distribution plates are spaced apart along the width direction of the curtain core 1. Thus, by providing a plurality of water distribution plates extending along the width direction of the curtain core 1, it is possible to avoid affecting the airflow into the air passage through the air passage hole, and to increase the water evaporation area, which helps to improve the humidification efficiency.

[0088] It should be noted that the two related technical features mentioned above, namely, "the water distribution component 14 is provided corresponding to the flow hole 13" and "the water distribution component 14 includes a plurality of water distribution plates extending along the width direction of the curtain core 1", can be set either one or both. Obviously, setting both at the same time will have a better effect.

[0089] Further, in one embodiment, please refer to Figure 6 The plurality of curtain cores 1 include a plurality of second curtain cores 1b. The bottom wall of the plurality of second curtain cores 1b is provided with the flow holes 13. The water distribution component 14 includes two water distribution plates and a guide. The two water distribution plates extend along the width direction of the curtain core 1 and are spaced apart. The guide ribs are respectively located between the corresponding flow holes 13 and the water distribution component 14, and can contact the upper surface of the two water distribution plates so that the downward projection of the flow holes 13 falls at least on the guide ribs. Since the flow holes 13 of the second curtain cores 1b are located in the middle, the water flowing down the second curtain cores 1b may flow directly away from the gap between the two water distribution plates. Therefore, the guide ribs connect the two water distribution plates, thereby filling the gap between the two water distribution plates, so that the water in the flow holes 112 first falls on the guide ribs and is diverted along the guide ribs 122 to the two water distribution plates, thereby achieving the diversion effect.

[0090] In one embodiment of the present invention, the flow holes 13 and the water distribution components 14 are respectively configured as water distribution groups. Multiple water distribution groups are arranged at intervals along the circumference of the curtain core 1. In this way, by setting multiple water distribution groups, the upper curtain core 1 can be evenly drained with water along its circumference, so that the water flow on the lower curtain core 1 can be evenly diffused, and the evaporation area of ​​the water flow can be increased, thereby helping to improve the humidification effect of the wet curtain assembly 100.

[0091] The present invention also provides a humidifier 1000, please refer to [link / reference]. Figures 10 to 11 The humidifier 1000 includes a housing 300, a wet curtain assembly 100, a water tank 400, and a fan assembly 500. The housing 300 has an air inlet, an air outlet, and a ventilation channel connecting the air inlet and the air outlet. The wet curtain assembly 100 is disposed within the ventilation channel. The water tank 400 is disposed within the housing 300 and located below the wet curtain assembly 100. The water tank 400 is used to guide water to the upper end of the wet curtain assembly 100 through a water supply assembly and to receive water flowing down through the wet curtain assembly 100. The fan assembly 500 is disposed within the ventilation channel and located above the wet curtain assembly 100. The fan assembly 500 is used to drive airflow from the air inlet to the air outlet.

[0092] Specifically, the air inlet is provided on the side surface of the housing 300, the air outlet is provided on the top of the housing 300, and the ventilation channel is formed in the inner cavity of the housing 300. The air inlet on the housing 300 should correspond to the evaporative cooling pad assembly 100, and the portion of the housing 300 corresponding to the fan assembly 500 should not have an air inlet. This is to prevent air from flowing directly into the fan assembly 500 without passing through the evaporative cooling pad assembly 100, thus avoiding ineffective humidification.

[0093] It should be understood that the water supply component can be configured as a water pipe 5 or other structures capable of water flow transportation; the present invention does not limit this. In this embodiment, the water pipe 5 can be located inside or outside the wet curtain assembly 100. In one embodiment, a limiting channel is formed on the side of the wet curtain assembly 100, and this limiting channel passes through multiple curtain cores 1, thereby positioning the water supply component. The upper end of the water supply component is installed in the water distribution box 4 via a water distribution cap, and the lower end is installed in the base 31 of the wet curtain assembly 100 via a water inlet cap.

[0094] It should also be noted that the specific structure of the wet curtain assembly 100 refers to the above embodiments. Since the humidifier 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0095] Furthermore, the humidifier 1000 also includes the wet curtain base 600, which overlaps with and is fastened to the upper end of the water tank 400. The wet curtain assembly 100 is mounted on the upper end of the wet curtain, and the fan assembly 500 is mounted on the upper end of the wet curtain assembly 100 and extends to the wet curtain through a connector and is fastened to the wet curtain, thereby forming a stable structure.

[0096] To improve water evaporation efficiency, in one embodiment of the present invention, please refer to... Figure 11 and Figure 12 The inner diameter of the curtain core 1 is d, and the inlet diameter of the fan assembly 500 is D, wherein 0.5≤d / D≤1, to ensure that sufficient humidifying gas flows into the fan assembly 500 so that the air volume of the wet curtain assembly 100 can be matched with the air volume of the fan assembly 500, so as to avoid the reduction of water evaporation efficiency due to insufficient air volume.

[0097] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
