Description

Technical Field

[0001] This utility model relates to the technical field of air humidification equipment, specifically to a humidifier water tank structure. Background Technology

[0002] The water tank is the core functional component of a humidifier. It is mainly used to store humidification water and distribute the water to the humidification medium (such as a wet curtain) through the water distribution system. Together with the airflow generated by the fan, it can regulate the air humidity.

[0003] Traditional humidifier water tanks typically only have basic water storage functions, and their structural design suffers from the following typical problems: First, the water inlet method is singular. Most humidifier water tanks use a 360° annular water inlet design, which, while covering multi-angle water filling needs, results in high structural complexity and is prone to poor sealing due to manufacturing errors. Second, the support structure for the filter assembly is redundant. Traditional solutions achieve partitioned support by adding an independent partition between the humidification chamber and the water tank, leading to an increase in the number of components, reduced assembly efficiency, and cumbersome operation requiring separate disassembly of the partition and filter assembly for later maintenance. Therefore, there is an urgent need for a new type of humidifier water tank structure that balances convenient water inlet, simplified structure, and easy maintenance. Utility Model Content

It also integrates functions such as water level monitoring and sterilization, thereby improving humidification efficiency and ease of use.

[0005] The present invention provides a humidifier water tank structure, comprising a shell, a fan, a humidification chamber, and a water tank arranged sequentially from top to bottom within the shell. The top of the shell has an air outlet grille communicating with the fan, and a water storage tank is located in the middle of the air outlet grille. A water inlet cover communicating with the water storage tank is fastened to the top of the air outlet grille. The top of the water inlet cover is a V-shaped water inlet formed by two inclined surfaces, and the bottom of the V-shaped water inlet has a water inlet communicating with the water storage tank. A detachable filter assembly is located inside the humidification chamber, and the bottom of the filter assembly is supported and fixed by the overall upper surface of the water tank. The filter assembly includes an inner wet curtain and a high-efficiency filter wrapped around the outer side of the wet curtain.

[0010] As a preferred technical solution of this utility model, the high-efficiency filter is U-shaped, and the housing is provided with a corresponding air inlet at the high-efficiency filter.

[0011] As a preferred embodiment of this utility model, the water tank cover is located inside the wet curtain and tilts downwards to the drain outlet, and a corresponding recycling hole is provided at the top of the water tank at the drain outlet.

[0012] As a preferred embodiment of this utility model, the water tank is further provided with a water level sensor for detecting water level and an electrolyzed water module for sterilization.

[0013] As a preferred technical solution of this utility model, a rear cover plate is provided at the rear of the housing for easy maintenance, and the humidification chamber and water tank are both located at the rear cover plate and are snapped into the interior of the housing.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] 1. Improved water inlet uniformity: The water inlet cover adopts a V-shaped water groove design with the water inlet located at the lowest point. Combined with an integrated filter screen, it can effectively guide the water flow to converge and intercept impurities.

[0016] 2.

[0033] In this utility model, the humidification chamber 3 is provided with a detachable filter assembly. The bottom of the filter assembly is supported and fixed by the overall upper surface of the water tank 4. The filter assembly includes an inner wet curtain 10 and a high-efficiency filter 11 wrapped around the outside of the wet curtain 10. The high-efficiency filter 11 has a U-shaped structure, and the housing 1 is provided with a corresponding air inlet 22 at the high-efficiency filter 11. The bottom of the wet curtain 10 and the high-efficiency filter 11 is provided with a water tank cover 12 for positioning and collecting water. The top of the wet curtain 10 is provided with a water distribution frame 13 for water supply. The water tank cover 12 is provided with a drain outlet 14 communicating with the water tank 4. The water tank cover 12 is located inside the wet curtain 10 and tilts downward to the drain outlet 14. The top of the water tank 4 is provided with a corresponding recovery hole 23 at the drain outlet 14.

[0034] In this utility model, the air inlet 20 with an inner diameter that gradually decreases from top to bottom is located inside the shell 1 at the bottom of the fan 2. The bottom of the air inlet 20 is located inside the wet curtain 10, and a humidifying filter 21 is provided inside the air inlet 20.

[0035] In this utility model, the water tank 4 is equipped with a circulating water pump 15.

During the snapping process, multiple spring pins for limiting are used for installation, which is convenient and quick.

[0037] Working principle

[0038] 1. Water addition stage: such as Figure 5 As shown, water is injected through the V-shaped water inlet 8 of the water inlet cover 7. The water flows along the slope of the V-shaped groove to the water inlet 9 at the lowest point. After impurities are filtered by the filter screen 17, the water enters the water storage tank 6 and flows into the water tank 4 for storage through the pipe on one side of the water storage tank 6.

[0039] 2. Humidification stage: such as Figure 6-7 As shown, the water in the water tank 4 is pressurized by the circulating water pump 15 and then transported to the water distribution rack 13 through the circulating water pipe 16. The water distribution rack 13 evenly sprays the water onto the wet curtain 10, where the moisture is absorbed to form a wet surface. Ambient air enters through the air inlet 22 on the housing 1, passes sequentially through the high-efficiency filter 11 (intercepting large dust particles), the wet curtain 10 (absorbing moisture and evaporating), and the humidifying filter 21 (filtering fine impurities), and is then accelerated and blown by the fan 2 to the air outlet grille 5. The airflow is evenly guided by the arc-shaped air guide plate within the U-shaped air outlet area and finally blown out from the entire area of ​​the air outlet grille 5, achieving large-area uniform humidification.

[0040] 3. Water cycle stage: such as Figure 6 As shown, the water that has not evaporated on the wet curtain 10 drips down along its fiber structure, flows into the drain outlet 14 through the inclined bottom surface of the water tank cover 12, and then flows back into the water tank 4 through the recycling hole 23 at the top of the water tank 4, forming a closed water cycle of "water tank 4 → circulating water pump 15 → wet curtain 10 → water tank 4", thus avoiding water waste.

[0041] 4. Functional control stage: The water level sensor 24 monitors the water level in the water tank 4 in real time. When the water level is lower than the set threshold, the control circuit board triggers an alarm. The electrolyzed water module 25 continuously electrolyzes the water in the water tank 4, decomposing the tap water into acidic electrolyzed water with bactericidal ability. The generated acidic electrolyzed water enters the wet curtain 10 with the water circulation and can play a bactericidal role after being blown out with the airflow. Users can view the real-time water level and operating mode through the display panel 18, and switch modes or adjust the humidification intensity through the control button 19.

[0042] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
