Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, and in particular to a wet curtain support structure for a mist-free humidifier. Background Technology

[0002] The principle of a mist-free humidifier is to humidify the environment by blowing water from a wet curtain through an airflow. This type of mist-free humidifier uses a water pump to draw water from the tank to the top of the wet curtain for humidification. When the wet curtain or filter is saturated, excess water flows back to the bottom tank and is then circulated back to the wet curtain by the pump. For example, patent number CN219415058U discloses a floor-standing mist-free humidifier with a concealed water filling structure. However, market feedback and testing have revealed the following problems:

[0003] 1. In order to connect the water pump, water level sensor and other electronic components on the lower side, the wet curtain bracket needs to be equipped with Hall plates and other circuit boards; during use, it is easily affected by water vapor or water flow, which poses a safety hazard of short circuit risk.

[0004] 2. When the water level in the tank is too low or the buoyancy is insufficient to make the float float, the humidifier's control program will determine that there is no water in the tank, and the humidifier's water pump will stop working at the same time. This results in a large amount of residual water remaining in the tank, or the water pump will not work or will keep running dry because the float in the tank is not moving smoothly.

[0005] 3. When the water under the wet curtain flows back to the bottom water tank, there will always be obvious running and dripping sounds, which will bother users of the humidifier and affect the customer experience.

[0006] Therefore, further improvements are needed. Utility Model Content

[0031] Example

[0032] Reference Figures 1 to 3 The present invention proposes a structure for a wet curtain support 40 of a mist-free humidifier, comprising: a water tank 10, a wet curtain assembly 20, a wet curtain support 30, and a wet curtain support 40; the wet curtain support 40 is mounted on the water tank 10, and the wet curtain support 30 is located above the wet curtain support 40; the wet curtain assembly 20 is installed on the wet curtain support 30.

[0033] The wet curtain support 30 is provided with a coupling groove 31 for embedding a coupler female seat and a transition groove 32 for embedding an adapter plate; the coupling groove 31 and the transition groove 32 are potted with epoxy resin; an ultrasonic water level detection unit 60 is installed at the bottom of the wet curtain bracket 40; the ultrasonic water level detection unit 60 is electrically connected to the adapter plate.

[0034] In this invention, epoxy resin is potted into the coupling groove 31 and the transition groove 32 to form an integrated sealed structure, effectively isolating moisture erosion and water infiltration, eliminating the risk of short circuit between the Hall plate and the circuit board, and enabling electronic components to operate stably in humid environments, significantly improving equipment safety and service life. A bottom-embedded ultrasonic water level detection unit 60 replaces the traditional float or Hall sensor structure, accurately identifying the water level through sound wave reflection, avoiding misjudgment caused by mechanical jamming, ensuring the water pump stops when there is a true water shortage, preventing waste of residual water, and solving problems such as water pump malfunction due to excessive water in the humidifier water tank 10, and water pump dry running.

[0035] In this embodiment, an opening 41 is provided on one side of the evaporative cooling pad bracket 40; the pump mounting bracket 50 can be inserted through the opening 41 and fixed inside the evaporative cooling pad bracket 40; the pump body and the ultrasonic water level detection unit 60 are mounted on the pump mounting bracket 50. The rigid fitting structure of the pump mounting bracket 50 and the evaporative cooling pad bracket 40 significantly improves the assembly stability of the pump body. Combined with the supporting role of the evaporative cooling pad bracket 40 in supporting the water tank 10, the vibration transmission path of the pump can be transformed from multi-point dispersion to overall frame absorption. While decorating the interior of the water tank 10, it effectively reduces the vibration of the pump, achieving an effective vibration damping effect. The vertical layout of the pump mounting bracket 50 built into the evaporative cooling pad bracket 40 ensures that the water pump suction port and the bottom of the water tank 10 maintain a constant water level contact depth. Combined with the liquid level in the evaporative cooling pad return channel, it effectively avoids and reduces the risk of dry pumping.

[0036] In this embodiment, the evaporative cooling pad bracket 40 is detachably equipped with a bracket side cover 70; the bracket side cover 70 can close the opening 41. The detachable design of the bracket side cover 70 forms a protective barrier by closing the opening 41, which on the one hand prevents foreign objects from entering the interior of the evaporative cooling pad bracket 40 and interfering with the operation of the water pump, and on the other hand, during maintenance, there is no need to disassemble the evaporative cooling pad assembly 20 or the water tank 10; the water pump and the fixing bracket can be directly accessed for radial maintenance simply by opening the side cover.

[0037] Specifically, the evaporative cooling pad support 40 has a first connecting post 42 inside, and the support side cover 70 has a second connecting post 71 corresponding to the first connecting post 42; the threaded part can pass through the second connecting post 71 and be locked to the first connecting post 42. The threaded locking mechanism between the first connecting post 42 and the second connecting post 71 adopts the principle of combined action of axial force constraint and radial positioning.

[0038] Furthermore, the water pump mounting bracket 50 is provided with a connecting lug 51, which can be engaged with the first connecting post 42 and pressed by the second connecting post 71. When the connecting lug 51 is engaged with the first connecting post 42, radial limiting is achieved, while the second connecting post 71 is further tightened by the threaded parts to eliminate axial movement clearance, ensuring that the water pump mounting bracket 50 is securely installed.

[0039] Preferably, at least two sets of the first connecting post 42, the second connecting post 71, and the connecting ear 51 are provided.

[0040] In this embodiment, a bottom recess 11 is provided in the middle of the water tank 10; the water pump is arranged near the bottom surface of the bottom recess 11. The funnel-shaped structure of the bottom recess 11 allows the water tank 10 to concentrate the residual water in the recess area when the water level is low. Combined with the bottom-mounted arrangement of the water pump, it ensures that the pump body suction port is always submerged in the water layer accumulated in the recess. Even if the total water volume of the water tank 10 drops below the safety threshold, water pumping can still be performed, reducing the residual water in the water tank 10 and preventing the water pump from running dry. This ensures that the water pump can still meet the pumping conditions when the machine detects a water shortage.

[0041] In this embodiment, the inner wall of the water pump mounting bracket 50 is provided with several guide ribs 52, the exposed ends of which are arranged in an inclined structure. The inclined guiding structure of the guide ribs 52 generates a self-centering effect when the water pump mounting bracket 50 is installed. The sliding friction between the inclined surface and the contact surface of the water pump housing guides the mounting bracket to be accurately positioned. After the water pump body and the ultrasonic water level detection unit 60 are inserted, they form an interference fit with the inner wall of the bracket, ensuring that the water pump has no risk of displacement or loosening under vibration.

[0042] In this embodiment, the wet curtain support 30 is provided with a drain outlet 33; the drain outlet 33 allows water from the wet curtain support 30 to fall onto the inner side of the wet curtain bracket 40; the wet curtain bracket 40 is provided with several protruding intercepting parts 43; the intercepting parts 43 are used to prevent water from flowing directly towards the bottom of the wet curtain bracket 40; adjacent intercepting parts 43 are directly connected with a flow gap 44. Through the staggered intercepting parts 43 and the flow gaps 44 on the wet curtain bracket 40, a stepped flow guiding channel is formed. The water flow is buffered by multiple interceptions during gravity fall, effectively reducing the water flow velocity. Combined with the fluid shearing effect of the flow gaps 44, the backflow noise can be effectively reduced, eliminating auditory interference during nighttime use. The sawtooth flow channel formed by the intercepting parts 43 causes the water flow to be divided into multiple curtain-like streams, avoiding concentrated water flow impacting the liquid surface of the water tank 10 and splashing, effectively reducing the phenomenon of water droplet bouncing.

[0043] Specifically, the upper part of the evaporative cooling pad support 40 is a bowl-shaped collecting bowl 45, and the lower part is a columnar support cylinder 46; the collecting bowl 45 and the support cylinder 46 are integrally formed. This integrated design of the collecting bowl 45 and the support cylinder 46 creates a continuous flow guiding space inside the evaporative cooling pad support 40. The bowl-shaped collecting bowl 45 can efficiently receive the water flowing vertically from the drain outlet 33 and guide the water flow to the central axis of the support cylinder 46 through its curved inner wall, avoiding turbulent noise caused by the water flow colliding with the side walls of the support.

[0044] In this embodiment, guide sidewalls 47 are provided on both sides of the intercepting section 43; the guide sidewalls 47 of two adjacent intercepting sections 43 are spaced apart to form a flow gap 44. The combined design of the guide sidewalls 47 and the flow gap 44 achieves fine control of the flow channel. Liquid surface tension is used to suppress water droplet dispersion. This structure makes the water flow present a continuous curtain-like shape at the outlet of the flow gap 44, which can effectively reduce the amount of discrete water droplet generation compared to a design without guide sidewalls 47.

[0045] Furthermore, the inner wall of the support cylinder 46 is provided with flow-guiding ribs 48; the flow-guiding ribs 48 extend from the flow gap 44 toward the bottom of the support cylinder 46. When water flows over the surface of the flow-guiding ribs 48, a boundary layer is formed due to the viscosity effect, isolating the core area of ​​the water flow from the cylinder wall and reducing the shear noise between the water flow and the air. At the same time, the flow-guiding ribs 48 divide the inner cavity of the support cylinder 46 into multiple independent flow channels, avoiding mutual interference and splashing of water flows with different directions.

[0046] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
