Description

Technical Field

[0001] The present invention relates to the technical field of humidifiers, and in particular to a humidifier and a wet curtain exhaust structure thereof. Background Art

[0002] Conventional mistless humidifiers typically rely on wet curtains for humidification. The core principle is to direct water to the top of the curtain and let it flow down the curtain, where it absorbs water and comes into contact with the air to achieve evaporative humidification. To ensure efficient humidification, a water distributor is used to evenly distribute the water across the top of the curtain, where it is then directed through drain holes onto the curtain surface.

[0003] However, existing water distributors have significant practical drawbacks: bubbles are easily generated within the cavity formed by the distributor and its cover due to factors such as water flow impact and waterway structural design. These bubbles accumulate in areas of the distributor away from the inlet, creating a "trapped air" phenomenon. This phenomenon blocks the flow of water from the distributor to the furthest outlet, causing water shortages in the outlet holes of the wet curtain away from the inlet, reducing humidification efficiency and causing uneven humidification across the wet curtain, impacting the humidification effect.

[0004] Therefore, in view of the technical defect of the existing water equalizer that the water equalizer supplies uneven water to the wet curtain due to "trapped air", it is urgent to propose an exhaust structure that can avoid the "trapped air" phenomenon in the water equalizer and ensure that the water flow on the water equalizer can be evenly distributed to various areas of the wet curtain. Summary of the Invention

[0005] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a humidifier and a wet curtain exhaust structure thereof, aiming to solve the technical problem of "air trapping" that is prone to occur in the water equalizer of the humidifier in the prior art.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A wet curtain exhaust structure for a humidifier includes a wet curtain bracket, a wet curtain and an upper water pipe. A water equalizer with a ring structure is provided on the top of the wet curtain bracket, and a water equalizer cover is provided on the top of the water equalizer; the water equalizer includes a bottom plate, an inner plate and an outer plate, the bottom plate is provided with a plurality of drain holes, and the outlet end of the upper water pipe is connected to the water equalizer; at least one exhaust hole is provided on the bottom plate, and the side wall of the exhaust hole protrudes and extends upward; the wet curtain is provided on the wet curtain bracket and is located below the water equalizer.

[0007] Furthermore, in the wet curtain exhaust structure of the humidifier, an exhaust hole is provided at least on the end of the bottom plate opposite to the outlet end of the upper water pipe.

[0008] Furthermore, in the wet curtain exhaust structure of the humidifier, the top of the side wall of the exhaust hole is lower than the top of the inner plate and the top of the outer plate of the water equalizer.

[0009] Furthermore, in the wet curtain exhaust structure of the humidifier, an inner slot and an outer slot are provided at the bottom of the water equalizer cover, the inner side plate of the water equalizer is inserted into the inner slot, and the outer side plate of the water equalizer is inserted into the outer slot.

[0010] Furthermore, in the wet curtain exhaust structure of the humidifier, a concave cavity is provided at the bottom of the water equalizer cover corresponding to the exhaust hole.

[0011] Furthermore, in the wet curtain exhaust structure of the humidifier, a water guide groove is provided at the bottom of the base plate, and the groove wall of the water guide groove protrudes and extends downward; each water drain hole and exhaust hole is connected to the water guide groove; the water guide groove is located directly above the wet curtain.

[0012] Furthermore, in the wet curtain exhaust structure of the humidifier, the bottom end of the water guide groove abuts against the top end of the wet curtain.

[0013] Furthermore, in the wet curtain exhaust structure of the humidifier, the diameter of each exhaust hole and the diameter of each drain hole are both smaller than the width of the water guide groove.

[0014] Furthermore, in the wet curtain exhaust structure of the humidifier, an annular boss is provided on the top of each drain hole, and the top of the annular boss is lower than the top of the side wall of the exhaust hole.

[0015] The present invention accordingly provides a humidifier, comprising a housing and a water tank. Different from the prior art, the humidifier further comprises the wet curtain exhaust structure of the humidifier described above.

[0016] Beneficial effects: The present invention provides a humidifier and a wet curtain exhaust structure thereof, which have at least the following advantages compared with the prior art: (1) By setting exhaust holes on the bottom plate of the water equalizer, exhaust channels are formed inside and outside the water equalizer, ensuring that the water holes in each area of ​​the water equalizer can be stably supplied with water, fundamentally solving the problem of uneven humidification of the wet curtain. As a preferred solution, the exhaust holes are set at the far end opposite to the outlet end of the water supply pipe, which can directly and efficiently exhaust the area where bubbles are prone to accumulate, avoiding "trapped air" and obstruction of water flow.

[0017] (2) Furthermore, the annular boss on the top of the drain hole can slow down the water flow speed and guide the water flow to spread evenly. Combined with the centralized directional diversion of the water flow by the water guide groove and the gap-free design of the water guide groove 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.

[0030] To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] See also Figures 1 to 11 The present invention provides a humidifier and a wet curtain exhaust structure thereof. The accompanying drawings are only used to explain the structural principles and are not proportional to the actual product. The accompanying drawings only depict structures related to the innovative points of this application, and some conventional structures are not specifically depicted. The "several" mentioned herein refers to a number greater than or equal to 1. Since the number of structures referred to is not an inventive point, it is not specifically limited.

[0032] First see Figures 1 to 4 The wet curtain exhaust structure of the humidifier includes a wet curtain bracket 1, a wet curtain 2 and an upper water pipe 3. A water equalizer 4 with a ring structure is provided on the top of the wet curtain bracket 1, and a water equalizer cover 5 is provided on the top of the water equalizer; the water equalizer 4 includes a bottom plate 40, an inner plate 41 and an outer plate 42. The bottom plate 40 is provided with a plurality of drain holes 6, and the outlet end 32 of the upper water pipe is connected to the water equalizer 4; at least one exhaust hole 7 is provided on the bottom plate, and the side wall 71 of the exhaust hole 7 protrudes and extends upward; the wet curtain 2 is arranged on the wet curtain bracket 1 and is located below the water equalizer 4.

[0033] The cavity formed between the water homogenizer and the water homogenizer cover becomes the space and channel for water flow in the water homogenizer. The connection between the water homogenizer and the water homogenizer cover is preferably ultrasonic welding, so that the two have a good sealing effect and prevent water from overflowing from the connection between the water homogenizer and the water homogenizer cover.

[0034] Please see further Figure 5 and Figure 6 When the humidifier is actually running, the bottom end of the upper water pipe is the inlet end 31, and the top end of the upper water pipe is the outlet end 32. When the water flows into the water equalizer from the outlet end of the upper water pipe, it will flow in the cavity formed by the water equalizer and the water equalizer cover, especially diffuse in the direction away from the outlet end of the upper water pipe (i.e., the upper water end). In this process, many factors such as the impact of the water flow and the structure of the cavity itself will cause bubbles to be generated. If these bubbles cannot be discharged, they will accumulate with the water flow to the far end (i.e., the part of the water equalizer away from the upper water end). If the bubbles accumulate and fill the drain hole at the far end, or the drain hole is blocked by the water flow, a "trapped air" phenomenon will occur, which will hinder the water in the water equalizer from flowing forward to the area of ​​the drain hole at the far end. The present application provides an exhaust hole on the bottom plate of the water equalizer, thereby forming a gas flow channel inside and outside the water equalizer, so that the air in the water equalizer can be discharged normally through the exhaust hole, thereby avoiding the "trapped air" phenomenon. Therefore, during operation, no matter whether the drain hole is blocked or not, the water in the water equalizer can flow forward to the area of ​​the far drain hole, ensuring that the water flow in the entire water equalizer is evenly distributed.

[0035] In the present application, the side wall of the exhaust hole protrudes and extends upward, so that the exhaust hole will not be used as a drain hole, ensuring the smooth discharge of gas and bubbles.

[0036] like Figure 2 As shown, preferably, an exhaust hole 7 is provided on at least the end of the bottom plate opposite to the outlet end 32 of the upper water pipe (i.e., the "upper water 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 position where "trapped air" is most likely to form and most affects the smooth flow of water. Providing an exhaust hole directly at this position not only serves as an air flow channel inside and outside the water equalizer, but also allows the bubbles accumulated at the far end to have the opportunity to be discharged from the exhaust hole. When the bubbles are pushed to this area by the water flow, they can be directly discharged from the cavity through the exhaust hole, fundamentally avoiding the accumulation of bubbles at the far end to form air blockage, ensuring that the water flow can smoothly reach the farthest drain hole, thereby ensuring the uniformity of water supply to each area of ​​the wet curtain by the water equalizer. In other words, when only one exhaust hole is provided on the bottom plate, the best position is the end of the bottom plate opposite to the outlet end of the upper water pipe, attached. Figure 2 The exhaust hole shown is set at this position.

[0037] See also Figure 7 Furthermore, the top of the vent sidewall 61 is lower than the top of the inner plate 41 and the top of the outer plate 42 of the water equalizer. Since the water equalizer cover is set on the water equalizer and the height of the vent sidewall is relatively low, it is ensured that the top of the vent sidewall will not interfere with the water equalizer cover, ensuring that the gas in the water equalizer can be discharged normally.

[0038] See also Figure 7 and Figure 11 Furthermore, the bottom of the water equalizer cover 5 is provided with an inner slot 51 and an outer slot 52. The inner plate 41 of the water equalizer is inserted into the inner slot 51, and the outer plate 42 of the water equalizer is inserted into the outer slot 52. By plugging the inner plate and the outer plate into the inner slot and the outer slot respectively, the relative position of the water equalizer cover and the water equalizer can be quickly positioned, ensuring the accuracy and convenience of assembly of the two. At the same time, this plug-in structure can form a tight fit on the contact surface, effectively closing the gap between the water equalizer and the water equalizer cover, preventing water from overflowing from the gap, ensuring that a relatively closed cavity is formed inside the water equalizer, allowing water to flow in the cavity and pass through each drain hole.

[0039] Please continue reading Figure 7 and Figure 11 Furthermore, a cavity 50 is provided at the bottom of the water equalizer cover, corresponding to the exhaust hole. The diameter of this cavity is larger than the diameter of the exhaust hole. The cavity increases the distance between the top of the exhaust hole's sidewall and the bottom of the water equalizer cover, avoiding structural interference between the exhaust hole and the water equalizer cover, and ensuring the smoothness of the gas exhaust channel.

[0040] See also Figures 7 to 10 Furthermore, a water guide groove 8 is provided at the bottom of the base plate, and the groove wall of the water guide groove (including the inner groove wall 81 and the outer groove wall 82) protrudes downward; each water hole and the exhaust hole are connected to the water guide groove; the water guide groove is located directly above the wet curtain. This setting has the following significance: (1) The water discharged from the water hole will flow into the water guide groove through the connection relationship with the water guide groove, 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 evenly receive moisture. (2) The gas discharged from the exhaust hole can be released through the space between the water guide groove and the wet curtain.

[0041] Furthermore, the bottom of the water channel 8 abuts the top of the wet curtain 2. This direct contact prevents water from drifting or splashing due to gravity after flowing out of the channel, ensuring that all water drawn from the channel precisely reaches the wet curtain, minimizing water loss. It should be noted that the wet curtain has a porous structure and high air permeability, so even if the bottom of the water channel abuts the top of the wet curtain, it does not affect normal airflow.

[0042] Furthermore, the diameter of each vent hole 7 and each drain hole 6 is smaller than the width of the water channel. The drain hole diameter is smaller than the water channel width, allowing the water discharged from the hole to fall completely into the water channel. Similarly, the vent hole diameter is smaller than the water channel width, allowing gas and bubbles in the exhaust air to easily enter the water channel.

[0043] like Figure 9 As shown, further, each drain hole 6 is provided with an annular boss 61 at the top, and the top of the annular boss 61 is lower than the top of the side wall 71 of the exhaust hole. The annular boss can form a certain obstruction and guidance effect on the water flow in the water equalizer cavity. When the water flows in the cavity, the annular boss can slow down the speed of the water flowing directly into the drain hole. At the same time, the annular boss can cause the water flow to form a temporary retention 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.

[0044] The top of the annular boss is lower than the top of the side wall of the vent hole, which prevents water from directly overflowing from the vent hole during the flow in the cavity, ensuring that the vent hole and the drain hole can respectively realize their respective functions.

[0045] The drain hole 6 and exhaust hole 7 are preferably circular. The smooth sidewalls of circular holes reduce resistance to water or gas flow. For drain holes, circular holes prevent eddies formed by sharp corners, which can cause localized stagnation of water flow and ensure uniform drainage. For exhaust holes, circular holes reduce turbulent flow interference, allowing bubbles to escape the cavity more smoothly and reducing exhaust resistance.

[0046] The present invention also provides a humidifier, comprising a housing and a water tank (not shown). Unlike the prior art, this humidifier also includes the aforementioned wet curtain exhaust structure. Because the humidifier differs from the prior art in the wet curtain exhaust structure, other conventional components (e.g., the housing, water tank, water supply device, etc.) are not shown in the accompanying drawings.

[0047] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all such changes or substitutions shall fall within the scope of protection of the present invention.
