Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically to a wet curtain bracket, wet curtain assembly, and humidification device. Background Technology

[0002] Humidifiers are generally divided into ordinary humidifiers and evaporative humidifiers. Compared with ordinary humidifiers, evaporative humidifiers have a larger humidification capacity and a more even humidification effect, and therefore have been widely recognized by users. Evaporative humidifiers utilize the principle of heat absorption during water evaporation. Water is sprayed onto a wet curtain through a distributor. When natural wind or internal air passes through the wet curtain, the water in the wet curtain evaporates, carrying away a large amount of latent heat from the air, thereby achieving the purpose of cooling and humidifying the indoor space.

[0003] Humidification capacity is one of the core performance parameters of evaporative humidifiers. The degree of wetting of the evaporative cooling pad directly affects the humidification capacity; the wetter the evaporative pad, the higher the overall humidification capacity of the unit. In existing evaporative humidifiers, the evaporative cooling pad is mounted on a support frame, which is entirely perforated. Due to the limited water absorption rate of the evaporative cooling pad, the water sprayed onto it by the distributor cannot be completely absorbed immediately. Excess water flows back through the perforated structure of the support frame into the water tank located below the evaporative cooling pad. Especially since the upper part of the evaporative cooling pad is far from the water tank, the unabsorbed water at the top of the pad drips directly down into the water tank through the perforated support frame, generating significant running water noise and affecting the user experience. Summary of the Invention

[0004] In view of this, the present invention provides a wet curtain bracket, a wet curtain assembly, and a humidification device to solve the problem that in existing humidification devices, unabsorbed water from the upper part of the wet curtain drips directly into the water tank, resulting in loud water flow noise and affecting the user experience.

[0005] In a first aspect, the present invention provides a wet curtain support bracket, disposed in a humidifying device, wherein the wet curtain of the humidifying device is sleeved on the outside of the wet curtain support bracket, the wet curtain support bracket comprising:

[0006] The receiving part is located at the upper part of the wet curtain support, and the receiving part is used to receive water dripping inward from the upper part of the wet curtain;

[0007] The perforated section is located at the lower part of the wet curtain support and is connected to the receiving part. Water that is not absorbed by the wet curtain flows back to the water tank of the humidification device through the perforated section.

[0008] Beneficial effects: The evaporative cooling pad bracket of the present invention has an evaporative cooling pad sleeved on the outside of the bracket. The bracket includes a receiving part and a hollow part. The receiving part is used to receive water dripping inward from the upper part of the evaporative cooling pad. This water can be absorbed by the evaporative cooling pad, or it can seep downward through the tiny gap between the inner wall of the evaporative cooling pad and the receiving part to the hollow part and then flow back to the water tank. The receiving part can guide and buffer the dripping water, thereby reducing the noise of water flow and improving the user experience.

[0009] In one alternative embodiment, the sidewall of the receiving portion is a continuous receiving surface.

[0010] Beneficial effects: In the evaporative cooling pad bracket of the present invention, the side wall of the receiving part of the evaporative cooling pad bracket is a continuous receiving surface. Since the evaporative cooling pad is sleeved on the outside of the evaporative cooling pad bracket, water that is not absorbed by the evaporative cooling pad drips inward. Since the side wall of the receiving part is a continuous receiving surface, all the water dripping inward from the evaporative cooling pad can drip onto the side wall of the receiving part first, thereby ensuring the effect of reducing water flow noise and enhancing the reliability of the structure.

[0011] In one alternative embodiment, the cross-sectional dimension of the receiving portion perpendicular to the axial direction gradually decreases from bottom to top.

[0012] Beneficial effects: In the wet curtain bracket of the present invention, the cross-sectional dimension of the receiving part perpendicular to the axial direction gradually decreases from bottom to top, that is, the cross-sectional dimension of the receiving part perpendicular to the axial direction is continuously reduced. This makes the side wall shape of the receiving part smoother, improves the noise reduction effect of the receiving part on water flow noise, and makes the user experience better.

[0013] In one alternative embodiment, the receiving part is a frustum-shaped structure.

[0014] Beneficial effects: The evaporative cooling pad bracket of the present invention has a frustum-shaped support structure. This structure can make full use of the space for the humidification device. The compact structure design makes it easy to install and manufacture, which helps to control manufacturing costs.

[0015] In one alternative embodiment, the sidewall of the receiving part is at least one of a continuous arcuate surface, a curved surface, or a folded surface along the circumferential direction.

[0016] Beneficial effects: The side wall of the receiving part of the evaporative cooling pad bracket of the present invention is a continuous surface along the axial direction, and the shape of the side wall of the receiving part can be at least one of arc surface, curved surface, and folded surface, which can be set up in a flexible and diverse manner to meet different usage needs.

[0017] Secondly, the present invention also provides a wet curtain assembly disposed in a humidification device, the wet curtain assembly comprising: a wet curtain and a wet curtain support as described above.

[0018] Since the wet curtain assembly of the present invention includes the wet curtain bracket of the present invention, it has the same beneficial effects as the wet curtain bracket of the present invention, which will not be described in detail here.

[0019] In one alternative embodiment, a receiving area is formed between the inner wall of the evaporative cooling pad and the receiving side wall of the evaporative cooling pad support, the receiving area being used to receive and temporarily store water dripping inward from the evaporative cooling pad.

[0020] Beneficial effects: The wet curtain support assembly of the present invention forms a receiving area between the inner wall of the wet curtain and the receiving side wall of the wet curtain support. Water dripping from the wet curtain is received by the receiving part and temporarily accumulated in the receiving area. The water accumulated in the receiving area is still in contact with the wet curtain, so that the wet curtain can absorb the dripping water a second time, realizing the full water absorption of the wet curtain, thereby improving the water absorption efficiency of the wet curtain and improving product performance.

[0021] In one alternative embodiment, the lower edge of the receiving portion is disposed close to the inner wall of the wet curtain.

[0022] Beneficial effects: In the wet curtain assembly of the present invention, the lower edge of the receiving part is closely attached to the inner wall of the wet curtain, so that a closed structure is formed between the inner wall of the wet curtain and the lower edge of the receiving part (i.e., the bottom of the receiving area is closed). Water dripping inward from the upper part of the wet curtain will accumulate on the closed structure. This water is in continuous contact with the wet curtain, so that the wet curtain can absorb the dripping water a second time, making the wet curtain fully absorb water, improving the water absorption efficiency of the wet curtain, and improving product performance.

[0023] In one alternative embodiment, the axial height of the evaporative cooling pad support is higher than or equal to the axial height of the evaporative cooling pad.

[0024] Beneficial effects: In the evaporative cooling pad support assembly of the present invention, the axial height of the evaporative cooling pad support is higher than or equal to the axial height of the evaporative cooling pad. The height and speed of the water dripping inward from the evaporative cooling pad are affected by the water flow of the liquid distribution mechanism. If the height or speed of the water dripping inward from the evaporative cooling pad is too high or too fast, the water dripping inward from the evaporative cooling pad may pass over the evaporative cooling pad support and fail to drip onto the receiving part of the evaporative cooling pad support. Therefore, designing the axial height of the evaporative cooling pad support to be higher than or equal to the axial height of the evaporative cooling pad ensures that the water dripping inward from the evaporative cooling pad will definitely drip onto the receiving part of the evaporative cooling pad support, thereby improving the reliability of the structure and ensuring the noise reduction effect of water flow.

[0025] Thirdly, the present invention also provides a humidification device, comprising:

[0026] Liquid distribution mechanism;

[0027] As described above, the wet curtain assembly is located below the liquid distribution mechanism, which sprays water onto the wet curtain of the wet curtain assembly.

[0028] A water tank, located below the wet curtain assembly, is used to recycle water that has not been absorbed by the wet curtain.

[0029] Since the humidification device of the present invention includes the wet curtain assembly of the present invention and has the same beneficial effects as the wet curtain assembly of the present invention, it will not be described in detail here. Attached Figure Description

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] On the market, the evaporative cooling pads of humidifiers are installed on evaporative cooling pad brackets. The shape of the evaporative cooling pad brackets matches the shape of the evaporative cooling pads. Usually, the evaporative cooling pads are columnar structures, such as cylindrical structures. Therefore, the common evaporative cooling pad brackets are generally columnar structures, such as cylindrical structures.

[0054] To allow for air circulation and to ensure that unabsorbed water flows back to the water tank, the evaporative cooling pad support is designed with a perforated structure. During operation, under gravity, unabsorbed water drips directly into the water tank through the perforated support, producing a loud "drip" sound, or water flow noise. This can be quite bothersome for users and negatively impact their experience.

[0055] The following is combined Figures 1-8 This describes embodiments of the evaporative cooling pad bracket, evaporative cooling pad assembly, and humidification device of the present invention.

[0056] According to an embodiment of the present invention, in a first aspect, a wet curtain support is provided, disposed in a humidifying device, wherein a wet curtain 1 of the humidifying device is sleeved on the outside of the wet curtain support 2, and the wet curtain support 2 includes: a receiving part 201 and a perforated part 202, the receiving part 201 being located at the upper part of the wet curtain support 2 and used to receive water dripping inward from the wet curtain 1; the perforated part 202 being located at the lower part of the wet curtain support 2 and connected to the receiving part 201, wherein water not absorbed by the wet curtain 1 flows back to the water tank 3 of the humidifying device through the perforated part 202.

[0057] In this type of wet curtain support 2, the receiving part 201 is used to receive water dripping inward from the upper part of the wet curtain 1. This water can be absorbed by the wet curtain 1, or it can seep downward through the tiny gap between the inner wall of the wet curtain 1 and the receiving part 201 to the perforated part 202 and then flow back to the water tank 3. The receiving part 201 can guide and buffer the dripping water, thereby reducing the noise of water flow and improving the user experience.

[0058] In a humidification device, the evaporative cooling pad bracket 2 is used to install and support the evaporative cooling pad 1. Therefore, the evaporative cooling pad bracket 2 should have sufficient structural strength to support the weight of the evaporative cooling pad 1 and the water it absorbs. Furthermore, since the evaporative cooling pad bracket 2 needs to be in contact with water for extended periods, it should be made of rust-resistant and corrosion-resistant materials, such as stainless steel, aluminum alloy, or plastic. In addition, the size and shape of the evaporative cooling pad bracket 2 should match the size and shape of the evaporative cooling pad 1, and its placement should be selected in conjunction with factors such as available space.

[0059] In this embodiment, the wet curtain support 2 is a columnar structure.

[0060] like Figures 1-2 As shown, the evaporative cooling pad support 2 includes a receiving portion 201 and a perforated portion 202. The receiving portion 201 is located at the upper part of the evaporative cooling pad support 2, and the perforated portion 202 is located at the lower part of the evaporative cooling pad support 2. The bottom of the receiving portion 201 is connected to the top of the perforated portion 202. This connection can be achieved by welding. Alternatively, the receiving portion 201 and the perforated portion 202 can be integrally molded to improve the manufacturing efficiency of the evaporative cooling pad support.

[0061] The receiving part 201 is used to receive water dripping inward from the wet curtain 1. In this embodiment, the receiving part 201 is used to receive water dripping inward from the upper part of the wet curtain 1. That is to say, water that is not absorbed in time from the upper part of the wet curtain 1 will first drip inward onto the receiving part 201, instead of dripping directly into the water tank 3. The water dripping inward from the upper part of the wet curtain 1 can be absorbed a second time by the wet curtain 1, or it can seep downward through the tiny gap between the inner wall of the wet curtain 1 and the receiving part 201 to the perforated part 202, and then flow back to the water tank 3 of the humidification device.

[0062] Furthermore, the sidewall of the receiving part 201 is a continuous receiving surface.

[0063] Since the wet curtain 1 is installed outside the wet curtain support 2, the water that the wet curtain 1 does not absorb in time drips inward. The side wall of the receiving part 201 is a continuous receiving surface (i.e. a closed receiving surface), so that all the water dripping inward from the upper part of the wet curtain 1 can drip onto the side wall of the receiving part 201 first, thus ensuring that the receiving part 201 reduces the noise of water flow and thereby enhances the overall reliability of the structure.

[0064] Since the evaporative cooling pad 1 is typically a columnar structure, in this embodiment, the sidewall of the receiving portion 201 is a continuous receiving surface along the circumference, so that the sidewall of the receiving portion 201 can correspond to the entire inner wall of the evaporative cooling pad 1. Furthermore, the receiving portion 201 has a certain height, and the area of ​​the sidewall of the receiving portion 201 can be selected and set according to the range of water dripping from the evaporative cooling pad 1; this embodiment does not impose any limitations on this.

[0065] Depending on the different setup requirements, the sidewall of the receiving part 201 can be at least one of a continuous arc surface, curved surface, or folded surface along the circumferential direction, making the setting of the receiving part 201 flexible and diverse to meet different usage needs.

[0066] In this embodiment, the sidewall of the receiving part 201 is a continuous arc-shaped surface along the circumferential direction.

[0067] Furthermore, the cross-sectional dimensions of the receiving part 201 perpendicular to the axial direction decrease from bottom to top.

[0068] Since the wet curtain 1 is installed outside the wet curtain support 2, and the water that the wet curtain 1 does not absorb in time will drip downwards due to gravity, the cross-sectional dimension of the receiving part 201 perpendicular to the axial direction decreases from bottom to top, which can ensure that the water dripping inward from the wet curtain 1 can drip onto the side wall of the receiving part 201, thereby improving the reliability of the structure and ensuring the noise reduction effect.

[0069] Since the bottom of the receiving part 201 is connected to the top of the hollow part 202, the cross-sectional dimension of the receiving part 201 perpendicular to the axial direction decreases from bottom to top. That is, the side wall of the receiving part 201 is inclined inward from bottom to top, so that the side wall of the receiving part 201 can be set towards the inner wall of the wet curtain 1. In this way, the side wall of the receiving part 201 can receive the water dripping inward from the wet curtain 1, so as to achieve the purpose of drainage and buffering of dripping water and reducing water flow noise.

[0070] Furthermore, the cross-sectional dimensions of the receiving part 201 perpendicular to the axial direction gradually decrease from bottom to top.

[0071] The cross-sectional dimension of the receiving part 201, perpendicular to the axial direction, gradually decreases from bottom to top, meaning the cross-sectional dimension of the receiving part 201 is continuously reduced. This results in a smoother sidewall shape for the receiving part 201, reducing the noise generated when water droplets fall onto it and thus improving its noise reduction effect on flowing water, leading to a better user experience. Furthermore, after water droplets fall onto the receiving part 201, the water flow can smoothly descend along its sidewall with minimal resistance, thereby accelerating water recovery efficiency.

[0072] In this embodiment, the receiving part 201 is preferably a frustum-shaped structure, with the diameter of its upper bottom surface being smaller than the diameter of its lower bottom surface. The specific dimensions of the diameter of its upper bottom surface and the diameter of its lower bottom surface can be set as needed.

[0073] The perforated part 202 is located at the lower part of the wet curtain support 2, and the water that is not absorbed by the wet curtain 1 flows back to the water tank 3 of the humidification device through the perforated part 202.

[0074] It should be noted that when the inner wall of the evaporative cooling pad 1 is tightly fitted against the lower edge of the receiving part 201 in the installed state, the space between the inner wall of the evaporative cooling pad 1 and the lower edge of the receiving part 201 is a closed structure. Water dripping inward from the upper part of the evaporative cooling pad 1 will accumulate on this closed structure. This water can only be absorbed by the evaporative cooling pad 1 a second time. Excess water that is not absorbed by the evaporative cooling pad can only flow back to the water tank 3 from the lower part of the evaporative cooling pad 1 through the perforation 202. However, when there is a small gap between the inner wall of the evaporative cooling pad 1 and the lower edge of the receiving part 201 in the installed state, water dripping inward from the upper part of the evaporative cooling pad 1 will seep down through this small gap to the perforation 202 and then flow back to the water tank 3. Therefore, water that is not absorbed by the evaporative cooling pad 1 can only flow back to the water tank 3 of the humidifying device through the perforation 202.

[0075] Since the top of the hollow part 202 is connected to the bottom of the receiving part 201, and the receiving part 201 is frustum-shaped, the hollow part 202 in this embodiment is a cylindrical structure.

[0076] Of course, in other embodiments, the hollow part 202 can also be a frustum shape, with the diameter of its upper bottom surface being larger than the diameter of its lower bottom surface, as long as it does not affect the supporting force of the wet curtain bracket 2 on the wet curtain 1.

[0077] The sidewalls of the hollowed-out portion 202 have a hollowed-out structure. Specifically, the hollowed-out portion 202 includes a plurality of supporting ribs 204, which are arranged at intervals along the circumference of the hollowed-out portion 202. Preferably, the plurality of supporting ribs 204 are evenly spaced along the circumference of the hollowed-out portion 202. There are hollowed-out gaps between adjacent supporting ribs 204, so that the interior and exterior of the hollowed-out portion 202 are connected through the hollowed-out gaps.

[0078] In this embodiment, eight support ribs 204 are provided, and the eight support ribs 204 are arranged symmetrically in pairs to ensure balanced support force. Furthermore, in this embodiment, the support ribs 204 have a certain width to improve the support force of the evaporative cooling pad bracket 2 on the evaporative cooling pad 1, thereby ensuring the structural strength of the evaporative cooling pad bracket 2.

[0079] In this embodiment, the top of the support rib 204 extends into the inner wall of the receiving part 201, so that the upper part of the support rib 204 is connected to the inner wall of the receiving part 201, thereby strengthening the structural connection and further improving the structural strength.

[0080] When the wet curtain 1 is installed outside the wet curtain bracket 2, the outer edge of the support rib 204 will fit against the inner wall of the wet curtain 1 to provide effective support for the wet curtain 1.

[0081] A bracket 205 is also provided at the bottom of the evaporative cooling pad support 2, which is used to support the evaporative cooling pad 1. Specifically, the bracket 205 is connected to the bottom of the support rib 204, and the outer diameter of the bracket 205 is larger than the maximum outer diameter of the receiving part 201 and the hollow part 202. The outer edge of the bracket 205 has an upwardly extending bracket wall, and an assembly space is formed between the outer edge of the support rib 204 and the bracket wall. The evaporative cooling pad 1 is suitable for being accommodated in this assembly space to realize the installation of the evaporative cooling pad 1.

[0082] The bracket 205 can be connected to the bottom of the support rib 204 by welding or other means, or the receiving part 201, the hollow part 202 and the bracket 205 can be integrally formed.

[0083] It should be noted that the hollow interior of the evaporative cooling pad bracket 2 is designed to allow airflow through it, accelerating the evaporation of water on the evaporative cooling pad 1, thereby achieving the humidification process.

[0084] The wet curtain bracket 2 in this embodiment can not only support the wet curtain as a conventional wet curtain bracket, but also solve the problem of excessive noise caused by excess water dripping from the upper part of the wet curtain into the water tank 3. It can greatly improve product performance and meet user needs.

[0085] like Figures 3-4 As shown, this embodiment also provides a wet curtain assembly, which is disposed in a humidification device. The wet curtain assembly includes: a wet curtain 1 and the aforementioned wet curtain bracket 2.

[0086] The evaporative cooling pad assembly is used in humidification devices and works in conjunction with other structures and devices within the humidification device to achieve the humidification function of the humidification device.

[0087] Specifically, the evaporative cooling pad assembly includes an evaporative cooling pad 1 and an evaporative cooling pad bracket 2. The evaporative cooling pad 1 is fitted over the evaporative cooling pad bracket 2, which supports and mounts the evaporative cooling pad 1. The evaporative cooling pad 1 is made of absorbent material and can absorb water and remain moist to enable the subsequent humidification process of the humidification device.

[0088] In this embodiment, the evaporative cooling pad 1 has a cylindrical structure, is hollow inside, and has a certain thickness in its sidewalls, such as... Figure 4 As shown.

[0089] To achieve a good support effect, the size and shape of the wet curtain 1 should match the wet curtain bracket 2 to prevent the wet curtain 1 from moving or shifting on the wet curtain bracket 2, which would affect the humidification effect.

[0090] Furthermore, the lower edge of the receiving part 201 is set close to the inner wall of the wet curtain 1.

[0091] If there is a large gap between the lower edge of the receiving part 201 and the inner wall of the wet curtain 1, water dripping inward from the upper part of the wet curtain 1 may flow directly down through the gap and back into the water tank 3, weakening the receiving function of the receiving part 201. In this embodiment, the lower edge of the receiving part 201 is set close to the inner wall of the wet curtain 1, so that a closed structure is formed between the inner wall of the wet curtain 1 and the lower edge of the receiving part 201. Water dripping inward from the upper part of the wet curtain 1 will accumulate on this closed structure. This water is in continuous contact with the wet curtain 1, allowing the wet curtain 1 to absorb the dripping water a second time, making the wet curtain 1 fully absorb water, improving the water absorption efficiency of the wet curtain 1, and improving product performance.

[0092] Of course, in other embodiments, the lower edge of the receiving part 201 may not be closed with the inner wall of the wet curtain 1, but may have a small gap. The water dripping inward from the upper part of the wet curtain 1 can still drip onto the side wall of the receiving part 201 first, and then this water will seep down through the small gap between the lower edge of the receiving part 201 and the inner wall of the wet curtain 1 to the perforated part 202, and then flow back to the water tank 3, which can also reduce the noise of water flow.

[0093] In this configuration, the receiving part 201 can both buffer and divert the dripping water without obstructing its downward flow. Water that is not absorbed by the wet curtain 1 (including the upper and lower parts) can still flow back to the water tank 3 through the perforated part 202 for subsequent recycling. Located between the wet curtain 1 and the water tank 3, the receiving part 201 buffers and diverts the dripping water from the wet curtain 1. The water, after being buffered by the receiving part 201, flows back to the water tank 3. Compared to a structure where water not absorbed by the wet curtain 1 drips directly back to the water tank 3, the wet curtain bracket 2 in this embodiment reduces the gravitational potential energy of the dripping water and significantly reduces water flow noise, thereby improving the user experience.

[0094] Furthermore, the axial height of the wet curtain support 2 is higher than or equal to the axial height of the wet curtain 1.

[0095] Because the height and speed of the water dripping inward from the upper part of the evaporative cooling pad 1 are affected by the water flow of the distribution mechanism, if the height or speed of the water dripping inward from the upper part of the evaporative cooling pad 1 is too high or too fast, the water dripping inward from the upper part of the evaporative cooling pad 1 may pass over the evaporative cooling pad support 2 and not drip entirely onto the receiving part 201 of the evaporative cooling pad support 2, thus weakening the function of the receiving part 201. Therefore, designing the axial height of the evaporative cooling pad support 2 to be higher than or equal to the axial height of the evaporative cooling pad 1 ensures that the water dripping inward from the upper part of the evaporative cooling pad 1 will definitely drip onto the receiving part 201 of the evaporative cooling pad support 2, thereby improving the reliability of the structure and ensuring the noise reduction effect of the water flow.

[0096] In this embodiment, the axial height of the wet curtain support 2 is equal to the axial height of the wet curtain 1.

[0097] In other embodiments, if the requirement for the receiving part 201 to receive the dripping water from the wet curtain 1 is not very strict, the axial height of the wet curtain support 2 can be slightly lower than the axial height of the wet curtain 1, but it cannot be too low. If the axial height of the wet curtain support 2 is too low than the axial height of the wet curtain 1, the structure of the receiving part 201 will completely fail and lose its function of receiving the dripping water.

[0098] Furthermore, a receiving area 203 is formed between the inner wall of the wet curtain 1 and the side wall of the receiving part 201 of the wet curtain support 2. The receiving area 203 is used to receive and temporarily store the water dripping from the wet curtain 1.

[0099] A receiving area 203 is formed between the inner wall of the wet curtain 1 and the side wall of the receiving part 201 of the wet curtain support 2. Water dripping from the wet curtain 1 will be received by the receiving part 201, and this water will temporarily accumulate in the receiving area 203. The water accumulated in the receiving area 203 is still in contact with the inner wall of the wet curtain 1, so that the wet curtain 1 can absorb the dripping water a second time, realizing the full water absorption of the wet curtain 1, thereby improving the water absorption efficiency of the wet curtain 1 and ensuring that the wet curtain 1 can be fully wetted.

[0100] In this embodiment, the receiving area 203 is a circumferentially arranged annular region. The lower edge of the receiving part 201 is closely attached to the inner wall of the wet curtain 1. Therefore, the cross-sectional shape of the receiving area 203 along the axial direction is triangular. The capacity of the receiving area 203 can be selected and set as needed. Since there is no obvious gap between the lower edge of the receiving part 201 and the inner wall of the wet curtain 1, the water dripping inward from the upper part of the wet curtain 1 will temporarily accumulate in the receiving area 203. The water in the receiving area 203 will slowly flow downward to the perforated part 202. During this process, the water in the receiving area 203 is continuously in contact with the inner wall of the wet curtain 1, and the water contained in the wet curtain 1 will be continuously lost as the humidification process continues. The water in the receiving area 203 can replenish the wet curtain 1 in time, realizing the secondary absorption of dripping water by the wet curtain 1, thereby improving the water absorption rate of the wet curtain 1.

[0101] like Figures 5-6 As shown, this embodiment also provides a humidification device, including: a liquid distribution mechanism, the above-mentioned wet curtain assembly, and a water tank 3. The wet curtain assembly is disposed below the liquid distribution mechanism, and the liquid distribution mechanism sprays water onto the wet curtain 1 of the wet curtain assembly. The water tank 3 is disposed below the wet curtain assembly and is used to recycle water that has not been absorbed by the wet curtain 1.

[0102] The liquid distribution mechanism, the wet curtain assembly, and the water tank 3 are arranged sequentially from top to bottom. The liquid distribution mechanism is used to spray water onto the wet curtain 1 of the wet curtain assembly to keep the wet curtain 1 moist. The liquid distribution mechanism is connected to the water tank 3 through a water supply pipeline assembly. The water tank 3 contains water, and the water in the water tank 3 is transported to the liquid distribution mechanism through the water supply pipeline assembly. Excess water that is not absorbed by the wet curtain 1 can also flow back to the water tank 3 to realize water recycling.

[0103] like Figure 7 As shown, the liquid distribution mechanism includes a liquid distributor 4, the lower surface of which has several water outlet holes 401 facing the evaporative cooling pad assembly. Specifically, the main body of the liquid distributor 4 is a ring structure, the diameter of which matches the diameter of the evaporative cooling pad assembly. The several water outlet holes 401 are evenly spaced around the circumference to ensure that water is sprayed evenly onto the evaporative cooling pad 1, so that the evaporative cooling pad 1 can absorb water evenly. At the same time, in order to keep the evaporative cooling pad 1 moist, the water flow rate of the liquid distributor 4 should be slightly greater than the water absorption capacity of the evaporative cooling pad 1.

[0104] The humidifier also includes a middle shell 6, the bottom of which is connected to the top of the water tank 3 to realize the installation of the overall outer shell of the humidifier. The liquid distribution mechanism and the wet curtain assembly are both located inside the middle shell 6.

[0105] like Figure 8 As shown, the humidification device also includes a water receiving bracket 5, which is located at the return port on the top of the water tank 3. The water receiving bracket 5 is a hollow funnel-shaped structure. Water dripping down from the hollow part 202 first passes through the water receiving bracket 5 for further diversion and buffering before entering the water tank 3, so as to enhance the noise reduction effect of water flow.

[0106] Of course, the humidification device in this embodiment also includes other structures and devices that are present in existing humidification devices. Since this embodiment does not involve these structures and devices, they will not be described in detail.

[0107] The working process of the evaporative cooling pad assembly in this embodiment will be described below with reference to the accompanying drawings:

[0108] When the humidifier starts working, the water in the water tank 3 is transported to the liquid distribution mechanism through the water supply pipeline assembly. The water outlet 401 of the liquid distributor 4 sprays water onto the wet curtain 1. In order to keep the wet curtain 1 moist, the water flow rate of the liquid distributor 4 is slightly greater than the water absorption capacity of the wet curtain 1. The water that the wet curtain 1 cannot absorb in time will drip inward onto the receiving part 201 of the wet curtain bracket 2. The water flows downward along the receiving part 201. Since the lower edge of the receiving part 201 is set close to the inner wall of the wet curtain 1, the downward flowing water will temporarily accumulate in the receiving area 203 and slowly flow downward to the hollow part 202. The water dripping down from the hollow part 202 is first buffered by the water receiving bracket 5 and then flows back into the water tank 3.

[0109] During the above process, the water absorbed by the wet curtain 1 continuously evaporates and is lost, and the inner wall of the wet curtain 1 is in continuous contact with the water accumulated in the receiving area 203, which allows the wet curtain 1 to absorb water in the receiving area 203 a second time, thereby improving the water absorption rate of the wet curtain 1. Moreover, due to the receiving part 201's receiving and diversion buffering effect on dripping water, the water dripping from the wet curtain 1 is prevented from falling directly into the water tank 3, greatly reducing the water flow noise generated thereby and improving the user experience.

[0110] In other embodiments, the cross-sectional shape of the wet curtain 1 and the wet curtain support 2 perpendicular to the axial direction can also be triangular, rectangular, polygonal, etc., and this embodiment does not limit this.

[0111] In other embodiments, depending on the distribution of water dripping inward from the wet curtain 1, the side wall of the receiving part 201 can also be a discontinuous receiving surface. It is sufficient to provide a receiving surface at the location where water easily drips inward from the wet curtain 1.

[0112] In other embodiments, the cross-sectional dimension of the receiving part 201 perpendicular to the axial direction can decrease from bottom to top. It does not necessarily have to decrease gradually. The cross-sectional dimension of the receiving part 201 perpendicular to the axial direction can decrease in a step-like manner from bottom to top. As long as the side wall of the receiving part 201 can receive the water dripping inward from the wet curtain 1 and guide the water downward back to the water tank 3, it is acceptable.

[0113] In other embodiments, the sidewall of the receiving part 201 may be one or more of the following: a continuous arc surface, a curved surface, or a folded surface. For example, the sidewall of the receiving part 201 may be a continuous curved surface, or a continuous folded surface, or may include both continuous arc surfaces and curved surfaces, or both continuous curved surfaces and folded surfaces, or both continuous arc surfaces, curved surfaces, and folded surfaces.

[0114] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
