The basic working principle of the existing pure humidifier is to use an evaporation filter screen to adsorb water. The lower part of the evaporation filter screen is immersed into water of the water storage tank, the water absorption performance of the evaporation filter screen is utilized, under the action of a fan, the water absorbed by the upper part (the part above the water surface) of the evaporation filter screen is rapidly evaporated through the circulating flow of air, so that the relative humidity of indoor air is increased, or a motor is adopted to drive the evaporation assembly to infiltrate into a water box in a large area, the water box is rotated out, the purpose of increasing the surface wetting area of the evaporation assembly is achieved, and then the water on the surface of the evaporation assembly is evaporated into water vapor and is dispersed into the air, so that the purpose of increasing the air humidity is achieved.

However, in this process, the evaporation assembly and the evaporation screen always have a portion that is not immersed in water, and the portion that is not immersed in water loses the evaporation area of the evaporation assembly and the evaporation screen, thereby reducing the working efficiency of the humidifier.

In order to solve the above-mentioned problem of evaporation area loss, a pure humidifier is proposed, and fig. 1 is a schematic diagram of an internal structure of a pure humidifier according to an exemplary embodiment. As shown in fig. 1, the pure humidifier according to the embodiment of the present application includes: the device comprises a shell 1, an evaporation assembly 2, a water feeding assembly 3 and a water tank 5, wherein the evaporation assembly 2, the water feeding assembly 3 and the water tank 5 are arranged inside the shell 1.

The water tank 5 and the housing 1 may be fixedly connected or detachably connected, which is not particularly limited in this embodiment, and in this embodiment, the water tank 5 and the housing 1 are preferably detachably connected, so as to facilitate cleaning of the water tank 5. The water tank 5 is provided inside the housing 1, and water is stored in the water tank 5, which is not limited to pure water or tap water in this embodiment. Because the humidification principle of the pure humidifier provided in the embodiment is that moisture is humidified by evaporation under the action of a fan or a blower, tap water can be used for humidification, other substances in the tap water cannot be evaporated and remain in the water tank, and the use cost of a user is reduced relative to purified water; compared with an ultrasonic atomization humidifier, the humidifier has the advantages that other influences on air can not be caused by water quality.

The shell 1 is provided with an air inlet and an air outlet, and water can be supplemented into the water tank 5 through the air inlet or the air outlet. In some embodiments, water can be added to the water tank 5 in other manners, for example, a water filling port is arranged at the bottom end of the shell, and corresponding structural design can be performed according to practical situations.

In this exemplary embodiment of the present application, a scale remover may be added to water for performing a scale removal treatment on the surface of the evaporation component 2, so as to prolong the cleaning time of the evaporation component 2, save manpower, or may also inject essence through the air outlet, keep indoor air fresh, or may inject other liquids into the water tank 5, which is not limited in this embodiment of the present application.

The water inlet 34 of the water feeding assembly 3 in this embodiment is arranged in the water tank 5, the water feeding assembly 3 comprises a water pump 31 and a water feeding pipe 32, the water pump 31 is arranged at the water inlet 34 of the water feeding assembly 3 and is used for extracting water in the water tank 5, the water inlet end of the water feeding pipe 32 is communicated with the water pump 31, the water outlet end of the water feeding pipe 32 faces the evaporation surface of the evaporation assembly 2, the water inlet end of the water feeding pipe 32 is configured as the water inlet 34 of the water feeding assembly 3, and the water outlet end of the water feeding pipe 32 is configured as the water outlet 33 of the water feeding assembly 3. Water is pumped out of the water tank 5 by the power of the water pump 31, and flows out of the water outlet 33 through the water supply pipe 32.

With continued reference to fig. 1, the water outlets 33 of the evaporation module 2 and the water supply module 3 are both located at the top of the water tank 5, and the evaporation module 2 is located below the side of the water outlet 33 facing the top of the water tank 5. The water outlet 33 of the water supply assembly 3 is directed towards the evaporation surface of the evaporation assembly 2, so that after water has flowed out of the water outlet 33, it falls onto the evaporation surface of the evaporation assembly 2 under the influence of gravity, and wets the entire evaporation surface as the evaporation assembly 2 rotates.

The working process of the pure humidifier of the embodiment of the application is that water is filled in the water tank 5, the water feeding assembly 3 is started, the water pump 31 in the water feeding assembly 3 pumps out the water in the water tank 5 and flows out from the water outlet 33 through the water feeding pipe 32, the discharged water falls onto the evaporation assembly 2, the evaporation assembly 2 is soaked and rotated by the water flow, and the rest water flows back into the water tank.

In addition, a fan assembly 4 is arranged above the water outlet 33, and air flow is generated by opening the fan assembly 4 and can flow in the shell 1 along the clearance between the evaporation assembly 2 and other components, so that water on the evaporation assembly 2 is evaporated, water vapor can flow out from the air outlet and is carried out to the outside of the shell 1, and the purpose of humidifying air is achieved.

It can be appreciated that the evaporation assembly 2 in the present application may be provided with a motor or other power components to perform rotation driving, or rotate under the action of gravity of water flow, so that the evaporation surface on the evaporation assembly 2 is wetted by water flow, the evaporation assembly 2 adopts a self-rotation mode, power components such as a motor can be reduced in assembly and use, and noise generated by using the power components is avoided. Specifically, in this exemplary embodiment of the present application, referring to fig. 3, fig. 3 is a schematic diagram of one of the structures of the evaporation assembly 2 in fig. 1. The evaporation assembly 2 may further include a rotation shaft 21 and a plurality of evaporation plates 22, the plurality of evaporation plates 22 are sleeved on the rotation shaft 21 at intervals, and the outer circumferential edges of the evaporation plates 22 intersect with the falling path of the water flow, so that when the evaporation plates 22 of the evaporation assembly 2 receive the falling water, the evaporation plates 22 at positions far from the water outlet 33 are rotated to positions close to the water outlet 33 in the rotation process due to gravitational potential energy of the water, and then are wetted by the water flowing out of the water outlet 33. In this way, the entire evaporation module 2 can be completely wetted and all evaporation plates 22 can be evaporated without loss of evaporation area.

Referring to fig. 4, fig. 4 is a schematic view of another structure of the evaporation module 2, and in some other examples, the evaporation module 2 further includes a driving module 23, where the driving module 23 is provided with a plate surface intersecting with a path of the water flow falling, which corresponds to the structure of the evaporation module 2 in fig. 3. Under the power of the water flow, the driving component 23 drives the evaporation component to rotate. The driving components 23 can be arranged at any position on two sides or in the middle of the rotating shaft 21, and the positions of the driving components 23 can be correspondingly adjusted according to the arrangement of the internal components of the actual shell 1. As shown in fig. 2, the evaporating plates 22 are a plurality of circular plates with water absorbing and evaporating effects, the evaporating plates 22 are sleeved on the rotating shaft 21 at intervals, and a plurality of evaporating plates 22 can be correspondingly arranged according to the whole width of the humidifier, so that more evaporating areas can be increased.

Moreover, as the evaporation plates 22 extend towards the water flow direction of the water outlet 33, the wetting effect of the water flow on the evaporation plates 22 is better, but the area capable of receiving the gravitational potential energy of the water flow is reduced under the impact of the water flow, and the rotation speed of the evaporation assembly 2 is affected, therefore, the connection rib plates are arranged between any two adjacent evaporation plates 22, the connection rib plates can be crossed with the flow direction of the water flow, the hand area of the evaporation assembly 2 is increased, the evaporation assembly can normally rotate, and the connection rib plates can also be made of the same material as the evaporation plates 22, and the evaporation area is further increased.

In addition, in the case that the detergent is added to the water tank 5, the detergent falls onto the evaporation surface together when the detergent falls onto the evaporation surface under water, and the cleaning effect on the evaporation surface is enhanced under the double effects of wetting the evaporation surface and the falling weight.

When water flows out of the water outlet 33 and falls onto the surface of the evaporation assembly 2, other water than the water wetting the evaporation surface flows onto the water guide plate 13 from the evaporation surface, flows onto the top inlet of the water tank 5 from the water guide plate 13, and returns into the water tank from the top inlet of the water tank 5, thereby realizing the recycling of the water.

In some embodiments, the end of the water guide plate 13 may form an angle with the top inlet of the water tank 5, so that water can flow back into the water tank 5, and by providing the water guide plate 13 between the evaporation assembly 2 and the water tank 5, buffering can be provided during the process of flowing back into the water tank 5, and noise is reduced.

In addition, an air channel can be formed between the water guide plate 13 and the evaporation component 2, and the air flow can only pass through between the water guide plate 13 and the evaporation component 2 after entering, and the air flow speed is increased after entering a narrower channel from a wider channel due to the smaller distance between the water guide plate 13 and the evaporation component 2, so that the evaporation efficiency of the evaporation component 2 can be improved. In some embodiments, the shape of the top of the water tank 5 may be designed directly to have a similar structure to the water guide plate 13, and the structural part of the water guide plate 13 may be omitted, but the same effect may be achieved, and the embodiment of the present application is not limited herein.
