Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, and in particular to a humidifier and its wet curtain exhaust structure. Background Technology

[0002] In existing technologies, mist-free humidifiers typically rely on evaporative cooling pads to achieve humidification. Their core principle is to guide water to the top of the evaporative cooling pad and allow it to flow down, utilizing the pad's absorbency to evaporate and humidify the air. To ensure efficient humidification, a water distributor must evenly distribute the water at the top of the pad before guiding it through drain holes to the pad's surface.

[0003] However, existing water distributors have significant drawbacks in practical use: air bubbles are easily generated within the cavity formed by the water distributor and its cover due to factors such as water flow impact and water channel design. These bubbles accumulate in areas of the water distributor far from the water inlet, creating a "trapped air" phenomenon. This phenomenon blocks the flow of water from the water distributor to the furthest drain hole, causing water shortage in the drain holes of the area of ​​the evaporative cooling pad far from the water inlet. This not only reduces humidification efficiency but also causes uneven humidification across different areas of the evaporative cooling pad, affecting the overall humidification effect.

[0004] Therefore, in order to address the technical defects of existing water distributors that cause uneven water supply to the evaporative cooling pads due to "trapped air", it is urgent to propose an exhaust structure that can avoid the "trapped air" phenomenon in the water distributor and ensure that the water flow can be evenly distributed to all areas of the evaporative cooling pad. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a humidifier and its wet curtain exhaust structure, which aims to solve the technical problem of "trapped air" that easily occurs in the water equalizer of the humidifier in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A humidifier's evaporative cooling pad exhaust structure includes an evaporative cooling pad support, an evaporative cooling pad, and a water inlet pipe. A ring-shaped water distributor is mounted on the top of the evaporative cooling pad support, and a water distributor cover is mounted on top of the water distributor. The water distributor includes a base plate, an inner side plate, and an outer side plate. The base plate has several drainage holes, and the outlet end of the water inlet pipe is connected to the water distributor. At least one exhaust hole is provided on the base plate, and the sidewall of the exhaust hole protrudes upwards. The evaporative cooling pad is mounted on the evaporative cooling pad support and located below the water distributor.

[0008] Furthermore, in the humidifier's evaporative cooling pad exhaust structure, at least one exhaust hole is provided on the bottom plate at the end opposite to the outlet end of the water inlet pipe.

[0009] Furthermore, in the humidifier's evaporative cooling pad exhaust structure, the top of the sidewall of the exhaust hole is lower than the top of the inner side plate and the top of the outer side plate of the water equalizer.

[0010] Furthermore, in the humidifier's wet curtain exhaust structure, the bottom of the water distributor cover is provided with an inner slot and an outer slot, the inner side plate of the water distributor is inserted into the inner slot, and the outer side plate of the water distributor is inserted into the outer slot.

[0011] Furthermore, in the humidifier's evaporative cooling pad exhaust structure, a recess is provided at the bottom of the water distribution cover corresponding to the exhaust hole.

[0012] Furthermore, in the humidifier's wet curtain exhaust structure, a water guide groove is provided at the bottom of the base plate, and the groove wall extends downward; all drain holes and exhaust holes are connected to the water guide groove; the water guide groove is located directly above the wet curtain.

[0013] Furthermore, in the humidifier's evaporative cooling pad exhaust structure, the bottom end of the water guide groove abuts against the top end of the evaporative cooling pad.

[0014] Furthermore, in the humidifier's evaporative cooling pad exhaust structure, the diameter of each exhaust hole and the diameter of each drain hole are smaller than the width of the water guide groove.

[0015] Furthermore, in the humidifier's wet curtain exhaust structure, each drain hole has an annular boss at its top, and the top of the annular boss is lower than the top of the side wall of the exhaust hole.

[0016] This utility model provides a humidifier, including a housing and a water tank, and unlike the prior art, it also includes the wet curtain exhaust structure of the humidifier described above.

[0017] Beneficial effects: This utility model provides a humidifier and its wet curtain exhaust structure, which has at least the following advantages compared with the prior art:

[0018] (1) By setting vent holes on the bottom plate of the water distributor, a discharge channel is formed inside and outside the water distributor, ensuring that the drain holes in each area of ​​the water distributor can supply water stably, fundamentally solving the problem of uneven humidification of the wet curtain. As a preferred solution, especially by setting vent holes at the far end opposite to the outlet end of the water supply pipe, the air can be efficiently vented directly in areas where air bubbles tend to accumulate, avoiding "trapped air" that would obstruct water flow.

[0019] (2) Furthermore, the annular protrusion at the top of the drain hole can slow down the water flow speed and guide the water flow to spread evenly. Combined with the water guide channel to concentrate and guide the water flow, and the gapless design of the water guide channel and the top of the wet curtain, the water can be accurately and evenly transferred to each area of ​​the wet curtain, significantly improving the humidification efficiency and stability.

[0040] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model is further described in detail below. It should be understood that the specific embodiments described herein are merely for explaining this utility model and are not intended to limit this utility model.

[0041] Please see Figures 1 to 11 This utility model provides a humidifier and its evaporative cooling pad exhaust structure. The accompanying drawings are for illustrative purposes only and are not proportional to the actual product. The drawings only depict structures relevant to the innovative aspects of this application; some conventional structures are not specifically shown. The term "several" in this document refers to a quantity greater than or equal to one. Since the quantity of the structures referred to is not a point of interest in this utility model, it is not specifically limited.

[0042] Please refer to the following first. Figures 1 to 4 The humidifier's evaporative cooling system includes an evaporative cooling pad support 1, an evaporative cooling pad 2, and a water inlet pipe 3. The top of the evaporative cooling pad support 1 is equipped with a ring-shaped water distributor 4, and the top of the water distributor is equipped with a water distributor cover 5. The water distributor 4 includes a base plate 40, an inner side plate 41, and an outer side plate 42. The base plate 40 is provided with several drain holes 6, and the outlet end 32 of the water inlet pipe is connected to the water distributor 4. The base plate is provided with at least one vent hole 7, and the side wall 71 of the vent hole 7 protrudes upward. The evaporative cooling pad 2 is mounted on the evaporative cooling pad support 1 and located below the water distributor 4.

[0043] The cavity formed between the water distributor and its cover serves as the space and channel for water flow within the distributor. The connection between the water distributor and its cover is preferably ultrasonically welded, ensuring a good seal and preventing water from overflowing from the connection point.

[0044] Please refer to further information. Figure 5 and Figure 6In actual operation of the humidifier, the bottom end of the water supply pipe is the inlet end 31, and the top end is the outlet end 32. When water flows into the water distributor from the outlet end of the water supply pipe, it flows within the cavity formed by the water distributor and its cover, especially spreading towards the outlet end (i.e., the water supply end) away from the water supply pipe. During this process, water flow impact and the cavity's own structure, among other factors, can cause air bubbles to form. If these bubbles cannot escape, they will accumulate at the far end (i.e., the area of ​​the water distributor away from the water supply end) with the water flow. If the bubbles accumulate and fill the drain hole at the far end, or if the drain hole is blocked by the water flow, a "trapped air" phenomenon will occur, hindering the water in the water distributor from flowing forward to the area of ​​the drain hole at the far end. This application provides an exhaust vent on the bottom plate of the water distributor, thereby creating a channel for gas flow inside and outside the water distributor, allowing the air inside the water distributor to be discharged normally through the exhaust vent, thus avoiding the "trapped air" phenomenon. Therefore, during operation, regardless of whether the drain hole is blocked or not, the water in the water distributor can flow forward to the area of ​​the far drain hole, ensuring that the water flow in the entire water distributor is evenly distributed.

[0045] In this application, the sidewall of the vent extends upward, so that the vent will not be used as a drain hole, thus ensuring the smooth discharge of gas and air bubbles.

[0046] like Figure 2 As shown, preferably, at least one vent 7 is provided on the bottom plate at the end opposite to the outlet end 32 of the water inlet pipe (i.e., the "water inlet end" mentioned above). The thrust of the water flow will gradually push the air in the cavity to the farthest area of ​​the water flow. This area is the key location where "trapped air" is most likely to form and most affects the smoothness of water flow. Providing the vent 7 directly at this location not only serves as an airflow channel inside and outside the water distributor, but also allows air bubbles accumulated at the far end to have the opportunity to be discharged from the vent 7. When the air bubbles are pushed to this area by the water flow, they can be directly discharged from the cavity through the vent 7, fundamentally preventing air bubbles from accumulating at the far end and forming air blockages, ensuring that the water flow can smoothly reach the drain hole at the farthest end, thereby ensuring the uniformity of water supply to each area of ​​the wet curtain by the water distributor. In other words, when only one vent 7 is provided on the bottom plate, the optimal location is the end of the bottom plate opposite to the outlet end of the water inlet pipe. Figure 2 The exhaust vent shown is located at this position.

[0047] Please see Figure 7 Furthermore, the top of the sidewall 61 of the vent is lower than the top of the inner side plate 41 and the top of the outer side plate 42 of the water distributor. Since the water distributor cover is set on the water distributor, and the height of the sidewall of the vent is relatively low, it ensures that the top of the sidewall of the vent will not interfere with the water distributor cover, ensuring that the gas inside the water distributor can be discharged normally.

[0048] Please see Figure 7 and Figure 11Furthermore, the bottom of the water distributor cover 5 is provided with an inner slot 51 and an outer slot 52. The inner side plate 41 of the water distributor is inserted into the inner slot 51, and the outer side plate 42 of the water distributor is inserted into the outer slot 52. By inserting the inner side plate and the outer side plate into the inner slot and the outer slot respectively, the relative position of the water distributor cover and the water distributor can be quickly positioned, ensuring the accuracy and convenience of their assembly. At the same time, this insertion structure can form a tight fit at the contact surface, effectively sealing the gap between the water distributor and the water distributor cover, preventing water from overflowing from the gap, and ensuring that a relatively closed cavity is formed inside the water distributor, allowing water to flow within the cavity and through each drain hole.

[0049] Please continue reading. Figure 7 and Figure 11 Furthermore, a recess 50 is provided at the bottom of the water distributor cover corresponding to the vent hole. The diameter of this recess is larger than the diameter of the vent hole. The recess increases the distance between the top of the side wall of the vent hole and the bottom of the water distributor cover, avoiding structural interference between the vent hole and the water distributor cover, and ensuring the unobstructed flow of gas.

[0050] Please see Figures 7 to 10 Furthermore, a water guide trough 8 is provided at the bottom of the base plate. The walls of the water guide trough (including the inner wall 81 and the outer wall 82) extend downwards. All drain holes and vent holes are connected to the water guide trough. The water guide trough is located directly above the wet curtain. This setting has the following significance: (1) Water discharged from the drain holes will flow into the water guide trough through the connection with the water guide trough, and will be directed to the wet curtain, accurately guiding the collected water to the corresponding area of ​​the wet curtain, ensuring that the wet curtain can receive water evenly. (2) Gas discharged from the vent holes can be released through the space between the water guide trough and the wet curtain.

[0051] Furthermore, the bottom end of the water guide trough 8 abuts against the top end of the evaporative cooling pad 2. This direct contact between the bottom end of the water guide trough and the top end of the evaporative cooling pad prevents water from deviating or splashing due to gravity as it drips out of the trough, ensuring that all water from the trough is precisely applied to the evaporative cooling pad, minimizing water loss. It should be noted that the evaporative cooling pad has a loose, porous structure with high air permeability; even with the bottom end of the water guide trough abutting against the top end of the evaporative cooling pad, normal air venting is not affected.

[0052] Furthermore, the diameters of each vent hole 7 and each drain hole 6 are smaller than the width of the water guide channel. The smaller diameter of the drain hole allows the water flowing out of the hole to fall completely into the water guide channel; similarly, the smaller diameter of the vent hole allows the gas and air bubbles in the vented air to easily enter the water guide channel.

[0053] like Figure 9As shown, each drain hole 6 is further provided with an annular protrusion 61 at its top, the top of which is lower than the top of the side wall 71 of the vent hole. The annular protrusion can obstruct and guide the water flow in the water equalizer cavity. When the water flows in the cavity, the annular protrusion can slow down the speed at which the water flows directly into the drain hole. At the same time, the annular protrusion can cause the water flow to stagnate briefly around it, allowing the water flow to spread more evenly to the surrounding area before being discharged through the drain hole, ensuring a more balanced water output from each drain hole.

[0054] The top of the annular boss is lower than the top of the side wall of the vent hole to prevent water from overflowing directly from the vent hole during the flow of water in the cavity, ensuring that the vent hole and the drain hole each perform their respective functions.

[0055] The drain hole 6 and vent hole 7 are preferably round holes. The sidewalls of the round holes are smooth, which reduces the resistance when water or gas passes through. For the drain hole, the round hole can avoid local stagnation caused by eddies formed by sharp corners, ensuring uniform drainage; for the vent hole, the round hole can reduce turbulent interference of gas flow, allowing bubbles to leave the cavity more smoothly and reducing exhaust resistance.

[0056] This utility model also provides a humidifier, including a shell and a water tank (not shown in the figure). Unlike the prior art, it also includes the evaporative cooling pad exhaust structure described above. Since the difference between the humidifier described above and the prior art lies in the evaporative cooling pad exhaust structure, other conventional structures (such as shell, water tank, water supply device, etc.) are not shown in the figures.

[0057] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. It is understood that those skilled in the art can make equivalent substitutions or modifications based on the technical solution and inventive concept of the present utility model, and all such modifications or substitutions should fall within the protection scope of the present utility model.
