[0029] Example

[0030] As people's demands become higher and higher, white powder-free evaporative humidifiers are increasingly accepted by the market. Among the evaporative humidifiers on the market, most are immersion wet curtains and water pump spray wet curtains. Immersion wet curtains are prone to mold and stink during use, and the user experience is not good. Considering this problem, designers tend to design water pump spray wet curtains. When the water pump spray wet curtain is designed above the water surface, it is necessary to establish a water channel between the water and the wet curtain. The existing water channels mostly include two independent and unconnected waterways and sewers. During processing, the waterway and sewer need to be processed separately. On the one hand, the assembly efficiency is low, and on the other hand, the mold opening cost is high.

[0031] To this end, this embodiment provides a humidifying device, which has high assembly efficiency.

[0032] In one embodiment, if Figures 1 to 5As shown, the humidifying device includes a water tank 1, a water pump 2, a wet curtain assembly 3, and a water path structure 4. The water tank 1 has a water storage chamber 101; the water inlet 201 of the water pump 2 is suitable for communicating with the water in the water storage chamber 101; the wet curtain assembly 3 is arranged above the water storage chamber 101, and the wet curtain assembly 3 has an upper water inlet 301 and a drain outlet 302; the water path structure 4 is an integrated structure, including a spaced-apart water inlet channel 401 and a return water channel 402, the upper end of the water inlet channel 401 is connected to the upper water inlet 301, the upper end of the return water channel 402 is connected to the drain outlet 302, the lower end of the water inlet channel 401 is connected to the water outlet 202 of the water pump 2, and the lower end of the return water channel 402 is connected to the inside of the water storage chamber 101.

[0033] In this embodiment, the upper end of the water inlet channel 401 is connected to the upper water inlet 301 of the wet curtain assembly 3, and the lower end of the water inlet channel 401 is connected to the water outlet 202 of the water pump 2, so that the water pump 2 in the water tank 1 can be sent to the wet curtain assembly 3 to supply water to the wet curtain assembly 3. When the air passes through the wet curtain assembly 3, the humidity of the air increases, and the water flowing down from the wet curtain assembly 3 can flow back to the water storage chamber 101 through the drain port 302 and the return water channel 402, so that the water is recycled. By integrating the water inlet channel 401 and the return water channel 402 into an integrated structure, the assembly efficiency can be improved and the mold opening cost can be saved.

[0034] It should be noted that the humidifying device also includes a main structure and a fan arranged in the main structure. The water tank 1 is assembled on the main structure, and the fan can guide the flow of air.

[0035] On the basis of the above embodiment, in a preferred embodiment, the water return channel 402 includes a guide surface 4021, and from top to bottom, the guide surface 4021 is inclined toward the direction close to the water inlet channel 401. In this embodiment, by providing the guide surface 4021, the water flowing down from the wet curtain assembly 3 can flow into the water storage chamber 101 along the guide surface 4021 after passing through the drain port 302, thereby avoiding the dripping sound when the water flows back and reducing the noise.

[0036] like Figure 1 As shown, the guide surface 4021 is arranged on a side away from the water inlet channel 401 .

[0037] On the basis of the above-mentioned embodiment, in a preferred embodiment, a downwardly concave water collecting tank 303 is provided at the bottom of the wet curtain assembly 3, a drain port 302 is provided on the side wall of the water collecting tank 303, and the top end of the guide surface 4021 extends to the side opposite to the drain port 302. In this embodiment, by providing the water collecting tank 303 and providing the drain port 302 on the side wall of the water collecting tank 303, the return water first flows into the water collecting tank 303, the bottom wall of the water collecting tank 303 plays a buffering role for the water, and the water flows out from the side wall of the water collecting tank 303, which can reduce the sound of water flow and further reduce noise.

[0038] On the basis of the above-mentioned embodiment, in a preferred embodiment, the bottom end of the return channel 402 extends to the bottom of the water storage chamber 101. In this embodiment, by extending the bottom end of the return channel 402 to the bottom of the water storage chamber 101, the return water flows along the guide surface 4021 to the bottom of the water storage chamber 101, which can further reduce the water flow sound and further reduce the noise.

[0041] like Figure 1 As shown, the main structure includes a base, and the water pump 2 is located above the base and below the water tank 1.

[0042] On the basis of the above-mentioned embodiments, in a preferred embodiment, the water outlet 202 of the water pump 2 penetrates the bottom wall of the water storage chamber 101 and extends to the top of the bottom wall of the water storage chamber 101, and an annular wall 1012 is provided on the bottom wall of the water storage chamber 101 around the water outlet 202 of the water pump 2, and the water inlet channel 401 is sealedly connected to the annular wall 1012 through the first sealing ring 5. In this embodiment, by providing the annular wall 1012 on the bottom wall of the water storage chamber 101 and making the lower end of the water inlet channel 401 sealedly connected to the annular wall 1012, it is possible to prevent the water in the water storage chamber 101 from flowing out through the gap between the water outlet 202 of the water pump 2 and the bottom wall of the water tank 1. In an alternative embodiment, the lower end of the water inlet channel 401 can penetrate the bottom wall of the water storage chamber 101 and be connected to the water outlet 202 of the water pump 2, and the water inlet channel 401 is sealedly connected to the bottom wall of the water storage chamber 101.

[0043] On the basis of the above embodiment, in a preferred embodiment, a first assembly annular groove 4011 is provided on the outer side of the lower end of the water inlet channel 401, and the first sealing ring 5 is provided in the first assembly annular groove 4011.

The water inlet 301 and the water outlet 302 are both arranged on the bottom cover 304; the wet curtain 305 is arranged on the bottom cover 304, such as Figure 3 As shown, the wet curtain 305 is annular; the mesh cover 306 is fixedly connected to the bottom cover 304 and surrounds the wet curtain 305, the mesh cover 306 is a hollow bracket and will not affect the air intake, and the mesh cover 306 is provided with a liquid distributor 308 located at the top of the wet curtain 305, an inner water supply channel 307 of the mesh cover 306, and the top of the water supply channel 307 is connected to the liquid distributor 308, and the top of the water inlet channel 401 passes through the water inlet 301 and is sealed with the bottom end of the water supply channel 307 through a second sealing ring 6. In this embodiment, the water in the water storage chamber 101 is pumped to the liquid distributor 308 along the water inlet channel 401 and the water supply channel 307 by the water pump 2. The liquid distributor 308 is provided with a plurality of evenly distributed liquid distribution holes, so that the water flows evenly to the wet curtain 305 to humidify the wet curtain 305. When the air passes through the wet curtain 305, the humidity of the air increases. The water flowing down from the wet curtain 305 can flow back into the water storage chamber 101 through the drain port 302 and the return water channel 402, so that the water can be recycled.

[0045] Further references Figure 3 The mesh cover 306 is provided with buckles, which can be connected to the bottom cover 304 through the buckles.

[0046] On the basis of the above embodiment, in a preferred embodiment, a second assembly annular groove 4012 is provided on the outer side of the top end of the water inlet channel 401, and the second sealing ring 6 is provided in the second assembly annular groove 4012. In this embodiment, the second assembly annular groove 4012 is provided to facilitate the fixed installation of the second sealing ring 6, and the second sealing ring 6 is not easy to fall off, thereby ensuring the sealing effect.
