Description

Technical Field

[0001] The utility model relates to the technical field of evaporative humidifiers, in particular to a humidifier with a novel water supply structure. Background Art

[0002] Evaporative humidifiers are used to increase the humidity in the air and can also improve air quality. At present, evaporative humidifiers mainly consist of a water tank, a wet curtain assembly, and a blowing assembly in terms of structure. After the water stored in the water tank wets the wet curtain, the blowing assembly stirs the air, causing the air to flow through the wet curtain to increase the humidity in the air and sending out the air with increased humidity, thereby completing the humidification of the air.

[0003] The water supply method of the humidifier usually uses an electric water pump to inject the water in the water tank onto the wet curtain. However, the electric water pump will generate relatively large noise and vibration during the water supply process, seriously affecting the user experience. At the same time, since the evaporative humidifier humidifies the air by driving the air flow to quickly flow through the wet curtain through the fan assembly, thereby taking out the water vapor on the wet curtain to moisten the air, when watering the wet curtain, it is not necessary to supply water in a large flow. When injecting water into the wet curtain through an electric water pump, the water flow is often large and the water injection is fast, which easily causes the wet curtain to become saturated quickly and the water to flow back into the water tank. At this time, it instead causes excessive energy consumption.

[0004] Therefore, there is an urgent need for a humidifier with a novel water supply structure at present. Content of the Utility Model

[0005] The purpose of the utility model is to provide a humidifier with a novel water supply structure. To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A humidifier with a novel water supply structure includes a machine shell, a wet curtain, and a fan assembly. A water tank is formed inside the machine shell. The wet curtain is arranged inside the machine shell and above the water tank. The fan assembly is arranged above the wet curtain. A water supply structure is arranged inside the water tank for intermittently injecting water into the wet curtain. The water supply structure includes:

[0007] A pump housing, which is fixedly installed inside the water tank and has a pumping chamber formed inside. An inlet valve and a water supply valve communicating with the water tank are arranged at the bottom of the pumping chamber;

[0008] An upper water pipe, one end of which is connected to the water supply valve and the other end extends above the wet curtain;

[0009] A pumping piston, which is slidably connected inside the pumping chamber along the axis direction of the pumping chamber;

[0010] A driving device, which is in transmission connection with the pumping piston and is used to drive the pumping piston to reciprocate, so as to pump water through the water inlet valve and supply water to the wet curtain along the water supply valve.

[0011] Further, the water supply pipe includes a first section and a second section. The first section is integrally formed with the pump housing, and the second section is inserted into the first section.

[0012] Further, the water supply pipe further includes a connecting section, which is of a U-shaped structure. One end is connected to the water supply valve, and the other end is inserted into the first section.

[0013] Further, a water distributor is provided above the wet curtain. The water distributor is formed with water channels corresponding to the wet curtain, and a plurality of water distribution holes are formed at the bottom of the water channels.

[0014] Further, the aperture of the water distribution holes gradually increases as the water distribution holes gradually move away from the water supply point of the water supply pipe.

[0015] Further, the number of the water distribution holes gradually increases as the water distribution holes gradually move away from the water supply point of the water supply pipe.

[0016] Further, both the water inlet valve and the water supply valve are one-way valves. The beneficial effects produced by the present utility model are as follows:

[0017] When injecting water into the wet curtain, the driving device drives the pumping piston to move upward in the pumping chamber, so that the water in the water tank is sucked into the pumping chamber through the water inlet valve. Subsequently, the driving device drives the pumping piston to move downward, so as to convey the water in the pumping chamber to the water supply pipe along the water supply valve, thereby injecting water into the wet curtain. Repeat the above actions to realize multiple water injections into the wet curtain. Since both the water inlet valve and the water supply valve are one-way valves, when the piston moves upward, the water inlet valve opens and the water supply valve closes; when the piston moves downward, the water inlet valve closes and the water supply valve opens, thus realizing smooth water injection. There is a time interval between two consecutive water injections into the wet curtain. Therefore, the wet curtain is not continuously injected with water, and the situation of excessive and saturated moisture in the wet curtain will not occur. At the same time, due to the intermittent water injection method, the water injection speed can be slowed down, and the water injection into the wet curtain can be stopped in time in combination with the saturation situation of the wet curtain, thereby avoiding excessive energy consumption.

Specific embodiments

[0022] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the embodiments does not limit the present utility model. The present utility model will be described in detail below with reference to the accompanying drawings.

[0023] An embodiment of the present utility model provides a humidifier with a novel water supply structure, which can reduce noise and vibration during the process of supplying water to the wet curtain 10. At the same time, it can slowly supply water to the wet curtain 10, effectively avoiding the waste of energy caused by over - watering the wet curtain 10.

[0024] Such as Figures 1-3As shown in the figure, a humidifier with a new water supply structure provided in this embodiment includes a machine shell, a wet curtain 10, and a fan assembly. A water tank 20 is formed inside the machine shell. The wet curtain 10 is arranged inside the machine shell and above the water tank 20. The fan assembly is arranged above the wet curtain 10. The water supply structure is arranged inside the water tank 20 and is used to extract the water inside the water tank 20 and intermittently add it to the wet curtain 10. The water supply structure further includes a pump housing 30, an upper water pipe 34, a pumping piston 35, and a driving device 36. Among them, the pump housing 30 is fixedly installed inside the water tank 20, and a pumping chamber 31 is formed inside. An inlet valve 32 and an upper water valve 33 communicating with the water tank 20 are arranged at the bottom of the pumping chamber 31. One end of the upper water pipe 34 is connected to the upper water valve 33, and the other end extends above the wet curtain 10. The pumping piston 35 is slidably connected inside the pumping chamber 31 along the axis direction of the pumping chamber 31. The driving device 36 is in transmission connection with the pumping piston 35 and is used to drive the pumping piston 35 to reciprocate, so as to pump water through the inlet valve 32 and supply water to the wet curtain 10 along the upper water valve 33. In this embodiment, both the inlet valve 32 and the upper water valve 33 are one-way valves. In this embodiment, the driving device 36 includes a motor installed on the pump housing 30, a driven wheel rotatably arranged at the bottom of the chamber 31, and a chain sleeved between the output shaft of the motor and the driven wheel. Among them, two holes for the chain to pass through are arranged on the piston 35, and the piston 35 is fixedly connected to the conveying chain. When the motor rotates forward, the piston 35 is pulled upward by the chain, so as to suck the water inside the water tank 20 into the chamber 31 through the inlet valve 32. Similarly, when the motor rotates reversely, the piston 35 is pulled downward by the chain, so as to press the water in the chamber 31 out along the upper water valve 33 into the upper water pipe 34 to supply water to the wet curtain 10. It should be noted that necessary sealing is set between the holes on the piston 35 and the chain to reduce the overflow of the water in the chamber 31 to the upper part of the piston 35 along the holes.

[0025] When injecting water into the wet curtain 10, the driving device 36 drives the pumping piston 35 to move upward within the pumping chamber 31, so that the water in the water tank 20 is sucked into the pumping chamber 31 through the water inlet valve 32. Subsequently, the driving device 36 drives the pumping piston 35 to move downward, so as to convey the water located in the pumping chamber 31 to the upper water pipe 34 along the upper water valve 33, thereby injecting water into the wet curtain 10. By repeating the above actions, multiple water injections into the wet curtain 10 are realized. Since both the water inlet valve 32 and the upper water valve 33 are one-way valves, when the piston 35 moves upward, the water inlet valve 32 opens and the upper water valve 33 closes; when the piston 35 moves downward, the water inlet valve 32 closes and the upper water valve 33 opens, thus realizing smooth water injection. There is a time interval between two consecutive water injections into the wet curtain 10. Therefore, the wet curtain 10 is not continuously injected with water, and the situation of excessive and saturated moisture in the wet curtain 10 will not occur. At the same time, due to the intermittent water injection method, the water injection speed can be slowed down, and the water injection into the wet curtain 10 can be stopped in a timely manner in combination with the saturation condition of the wet curtain 10, thereby avoiding excessive energy consumption.

[0026] In this embodiment, the upper water pipe 34 is provided with a segmented structure. Among them, the upper water pipe 34 includes a first section 341 and a second section 342. The first section 341 is integrally formed with the pump housing 30, and the second section 342 is inserted into the first section 341. At the same time, the upper water pipe 34 also includes a connecting section 343. The connecting section 343 has a U-shaped structure, one end is connected to the upper water valve 33, and the other end is inserted into the first section 341. By setting the upper water pipe 34 into three sections, it is convenient for docking, and at the same time, the bending of the upper water pipe 34 can be reduced, thereby avoiding affecting the smoothness of water injection into the wet curtain 10 due to the bending of the water pipe.

[0027] In order to make the water evenly distributed on the wet curtain 10 after water supply to the wet curtain 10 and avoid the situation that some areas of the wet curtain 10 are rich in water while some areas are lacking water, a water equalizer 11 is further provided on the wet curtain 10. The water equalizer 11 is formed with water channels 12 corresponding to the wet curtain 10, and a number of water distribution holes are formed at the bottom of the water channels 12.

[0028] In this embodiment, the aperture of the water distribution holes gradually increases as the water distribution holes gradually move away from the water supply point of the upper water pipe 34.

[0029] In other embodiments, the number of the water distribution holes gradually increases as the water distribution holes gradually move away from the water supply point of the upper water pipe 34.

[0030] By setting the water diversion holes, after the water supply pipe 34 injects water into the water channel 12, due to the different settings of the water diversion holes at the water inlet point and away from the water inlet point, the amount of water dripping towards the wet curtain 10 at the near water inlet point and the far water inlet point can be made substantially the same, thus avoiding the uneven water supply to the wet curtain 10.

[0031] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in any form. Although the present invention is disclosed above in a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, when making some changes or modifications using the above-disclosed technical content as equivalent embodiments of equivalent changes, but as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical means of the present invention shall fall within the scope of the technical solution of the present invention.
