Description

Technical Field

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

[0002] A humidifier is a household or commercial environmental control device that combines air purification and humidification. Its core principle is to increase air humidity by evaporating moisture through a wet curtain, while simultaneously using a filter to remove dust, particulate matter, and other pollutants from the air, thereby improving indoor air quality. Traditional humidifiers often employ a distributed layout for their circuit control units, with each functional module (such as the fan drive circuit, water pump control circuit, and sensor interface) independently configured. This results in complex internal wiring and high maintenance difficulty. Furthermore, the circuit terminals and external connections often use simple plug-in or exposed designs, lacking sufficient waterproof sealing. Over time, moisture can easily seep in through the wiring gaps, causing short circuits or component corrosion, severely impacting the device's lifespan and operational stability.

[0003] The problems existing in the prior art are mainly reflected in the following two aspects: First, the decentralized structure of the circuit control unit results in low utilization of the internal space of the equipment, and multiple parts need to be disassembled one by one during assembly and maintenance, which is cumbersome; Second, the circuit wiring parts lack effective waterproof sealing design, and moisture can easily seep in through the terminal gaps or connection gaps, leading to frequent circuit failures and reducing the reliability of the equipment.

[0030] Example 1:

[0031] As per the instruction manual Figure 1-5 As shown, a purifying humidifier has a housing 1 made of ABS plastic injection molding. The interior is arranged from top to bottom as follows: water inlet 2, fan 3, wet curtain 4, and water tank 5. The water inlet 2 and the water tank 5 are directly connected by a pipe. The front of the housing 1 is a front panel 6, and a mounting bracket 8 is fixed to the inside of the front panel by screws. The circuit control unit adopts an integrated circuit board module 9. The module is encapsulated with epoxy resin, with only the connecting wires 10 leading out. The module body is fixed to the mounting bracket 8 by countersunk screws.

[0032] In this utility model, a water supply pipe 11 is sandwiched in the middle of the integrated circuit board module 9, and circulating water interfaces 12 are symmetrically arranged on its upper and lower sides; the two ends of the water supply pipe 11 are connected to the water supply pipe 14 in the middle of the circulating water interface 12 through sealing pipes 17; the inside of the connecting shell 13 of the circulating water interface 12 is divided into wiring cavities 15 on both sides of the water supply pipe 14, and the two ends of the connecting shell 13 are divided into fixing cavities 16. The fixing cavity 16 is connected to the plug seat 20 on the front panel 6, and the gap between the plug seat 20 and the fixing cavity 16 is filled with shock-absorbing glue 21.

[0033] In this utility model, a limiting plate 22 is integrally formed inside the fixed cavity 16, which matches the shape of the plug-in seat 20; the fixed cavity 16 and the plug-in seat 20 are connected by bolts from the rear of the circulating water interface 12 and threadedly connected to the plug-in seat 20, with the bolt head pressing against the rear of the limiting plate 22 to lock the fixed cavity 16 and the plug-in seat 20; a first sealing gasket 23 is press-fitted at the connection between the rear of the circulating water interface 12 and the sealing cover 18, and the sealing cover 18 is snapped onto the top surface of the water tank 5 and the wet curtain 4 by a buckle, with a circulating water pipe 19 inserted into the middle of the cover to connect with the water supply pipe 14.

[0034] In this utility model, a copper connector clip 24 is provided inside the wiring cavity 15. Its front end is welded and fixed to the connecting wire 10, and a Y-shaped plug interface 25 is provided at the rear end. A connecting guide 26 is provided inside the sealing cover 18 at the position corresponding to the plug interface 25. The connecting guide 26 passes through the sealing connection groove 27 and is plugged into the connector clip 24. The sealing connection groove 27 is filled with a silicone rubber sealing gasket 28, and a second sealing gasket 29 made of nitrile rubber is provided behind it to prevent water vapor in the water tank 5 from entering the wiring cavity 15.

[0035] In use, the user starts the device via the control screen 30 on the front panel 6. The circulating water pump 7 transports water from the water tank 5 through the circulating water pipe 19 and the water supply pipe 14 to the water delivery pipe 11, and finally sprays it onto the wet curtain 4. The fan 3 drives external air to flow through the wet curtain 4, and the water evaporates to form humidified air, which is then discharged, thus achieving the humidification function. At the same time, dust in the air is intercepted by the pre-filter, completing the purification process. The circuit control unit supplies power to the fan 3, the circulating water pump 7, and the sensors through the wiring clips 24 and the connecting guides 26, ensuring that all functional modules operate in coordination.

[0036] Working principle

[0037] 1. Water circulation: The water in the water tank 5 is pressurized by the circulating water pump 7, and transported through the circulating water pipe 19 to the water supply pipe 14 of the circulating water interface 12, and then flows into the water supply pipe 11 on one side of the integrated circuit board module 9, and finally sprays onto the wet curtain 4; the water that is not evaporated flows back to the water tank 5 along the bottom of the wet curtain 4, forming a closed-loop water circuit.

[0038] 2. Air handling: The operation of the fan 3 generates negative pressure, and the outside air enters through the air inlet 31 in the middle of the housing 1. When it flows through the wet curtain 4, it comes into contact with the wet surface of the wet curtain 4, and the moisture evaporates to increase the air humidity. Dust and particulate matter in the air are intercepted by the pre-filter 32, which is located on the outside of the wet curtain 4. The purified humid air is discharged from the air outlet 33 on the outside of the water inlet 2 at the top of the housing 1.

[0039] 3. Circuit Control: The integrated circuit board module 9 integrates the main control chip, motor drive circuit and water level detection circuit. The fan 3 and circulating water pump 7 are powered by the wiring clip 24 and the connecting guide 26 respectively, and the water level of the water tank 5 is monitored in real time. The user inputs the humidification requirements (such as target humidity, wind speed, etc.) through the control screen 30. The main control chip adjusts the speed of the fan 3 and the power of the circulating water pump 7 according to the feedback signal to achieve intelligent control.

[0040] 4. Waterproof protection: The gap between the fixed cavity 16 of the circulating water interface 12 and the plug-in seat 20 of the front panel 6 is filled with shock-absorbing glue 21 to avoid rigid collision; the sealing cover 18 cooperates with the first sealing gasket 23 and the second sealing gasket 29 to block the path of water vapor from the water tank 5 and the wet curtain 4 to the circuit module, ensuring that the circuit part operates stably in a humid environment.

[0041] 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.
