Description

Humidifying device and air supply device

Technical Field

The utility model relates to the technical field of humidification, in particular to a humidification device and an air supply device.

Background

Generally, an air blower with a humidifying function is used for atomizing water into fine particles or evaporating water into a vapor state, and then blowing out air with moisture by an air blowing unit such as a fan blade to increase the air humidity of a target space. A conventional air blower with a humidification function generally includes a water tank for storing humidification water, a water breaker for atomizing or evaporating water, and an air supply duct for blowing air containing moisture out of the air blower, and the water tank is disposed in the air supply duct.

Conventionally, as described in patent document (CN201287102Y), an air humidifier is specifically described, which includes, as shown in fig. 1, a power supply, a blower, an atomizing chamber, a water level sensor, an ultrasonic atomizer, an overflow port, a water inlet, a mist outlet, a water supply pipe, a water storage tank, a water pump, a water shortage sensor, and an electromagnetic valve. Wherein, the water in the atomizing chamber is atomized into water vapor under the action of the ultrasonic atomizer and mixed into the air in the atomizing chamber. The air containing the water vapor is blown out of the atomizing chamber through the mist outlet under the action of the blower. This forms a humidification air passage from the atomizing chamber to the mist outlet. Part of the humidification air duct is located above the liquid surface in the atomization chamber. Along with the operation of the humidifying function, the water in the atomizing chamber is atomized into water vapor and then blown out, and the liquid level of the water in the atomizing chamber is reduced. When the water level in the atomizing chamber is reduced to the lowest water level, the inductive switch of the water level inductor is closed, the water pump is controlled to inject water into the atomizing chamber, and the water in the water storage tank is injected into the atomizing chamber through the water supply pipe and the water inlet. Therefore, automatic water replenishing is realized, manual frequent water adding is not needed, and the use is convenient.

However, in the air humidifier disclosed in the patent document, the larger the space of the humidification air passage is, the higher the air blowing efficiency is, while other conditions are not changed. When the humidifying function is operated, the water level in the atomizing chamber is reduced, the space of the humidifying air path is increased, and the air supply efficiency is improved. When the water level in the atomizing chamber is reduced to the lowest water level at which the humidifying function normally works, the space of the humidifying air path is the largest, and the air supply efficiency is the highest. At this time, the water level sensor controls the water pump to fill water into the atomizing chamber, the water level rises again, and the space of the humidification air passage is compressed again. When the water level is raised to the highest level, the space of the humidification air path is the smallest, and the air supply efficiency is the lowest.

In the operation process of the humidifying function, the change of the air supply efficiency can possibly cause the change of the humidifying efficiency, the instability of the air supply volume and the humidifying efficiency can possibly reduce the user experience, and even the service life of a motor of the air feeder is reduced or damaged.

As described in the patent document, although the water level in the atomizing chamber can be controlled by the water level sensor, the water pump, the solenoid valve, and the like, if the liquid level in the atomizing chamber is maintained at the minimum water level, that is, if the liquid level is maintained at the critical height at which the water level sensor is set, the water level sensor may frequently send signals of water shortage and water fullness alternately, and the water pump or the solenoid valve may be frequently turned on and off. Thereby reducing the service life of the water pump or the electromagnetic valve and even damaging the water pump or the electromagnetic valve.

Therefore, there is a need for a humidification apparatus that can maintain humidification efficiency stably and efficiently, while suppressing a reduction in the life of humidification components.

In alternative embodiments, the humidifying water tray may have other shapes, and may be configured in a cylindrical shape, an elliptic cylindrical shape, or other irregular figure shapes, for example, the humidifying water tray may also be composed of two water trays which are communicated with each other and with the external air of the humidifying device. The mutual communication means that the liquid can flow mutually and the liquid level between the two water trays is kept consistent according to the principle of the communicating vessel. The shape and the size of the humidifying water tray can be adjusted according to actual needs so as to meet different requirements for storing humidifying liquid.

As shown in fig. 2, the humidifying unit 214 is disposed above the humidifying water tray 213, and is used to atomize or vaporize the liquid stored in the humidifying water tray 213, so as to be mixed with the air flowing through the humidifying unit 214.

The humidification water inlet 211 is provided below the water shortage detection unit 212. In this embodiment, the horizontal plane of the humidification water inlet 211 is located below the horizontal plane of the water shortage detection unit 212, that is, the distance between the upper end of the humidification water inlet 211 and the humidification water tray bottom surface 2132 is smaller than the distance between the humidification water tray bottom surface 2132 and the humidification water inlet 211, and the projection of the humidification water inlet 211 on the humidification water tray bottom surface may overlap with the projection of the water shortage detection unit 212 on the humidification water tray bottom surface, or may not overlap with the projection.

As shown in fig. 2 to 6, the water supply unit 220 supplies the humidifying unit 210 with liquid for humidification, and includes a water storage unit 300, a water supply switch unit 320, a water delivery unit 340, and an aeration unit 400.

The water storage unit 300 is a hollow box and includes a water storage unit outlet 310 and a water storage unit air vent 360. In this embodiment, the water storage unit 300 is a six-sided box, and in the installed state, the water storage unit 300 includes a bottom surface located below in the gravity direction, a top surface located above the bottom surface, and a side surface connecting the bottom surface and the top surface. In other alternative embodiments, the water storage unit may be provided in other regular shapes, such as a cylinder, or other irregular shapes.

The water storage unit outlet 310 is an opening provided at a lower portion of the water storage unit 300 and used for discharging liquid out of the water storage unit 300. In the present embodiment, the lower portion of the water storage unit refers to a center line of the tank of the water storage unit 300 in the gravity direction, and the water storage unit drain port 310 is located below the center line. For example, the water storage unit drain 310 is disposed on a bottom surface of the water storage unit. Or the water storage unit water outlet is arranged at the position, close to the bottom surface, of the side wall of the water storage unit, or the water storage unit water outlet is arranged at the joint of the side wall and the bottom surface of the water storage unit, and the like.

The water storage unit air vent 360 is disposed at an upper side of the water storage unit 300 for allowing air to enter the water storage unit. In the practice of the present disclosure, water cell vent 360 is disposed on a sidewall of water cell 300 near the top surface. In other alternative embodiments, the water cell vent 360 may be disposed on the top surface of the water cell.

As shown in fig. 4 and 6, the water storage unit 300 further includes a water delivery unit 340 connecting the water storage unit drain port 310 and the humidification water inlet port 211. In this embodiment, the water delivery unit 340 is a hollow tube connecting the water storage unit water outlet 310 and the humidification water inlet 211, and the liquid in the water storage unit 300 is injected into the humidification water tray 213 from the water storage unit water outlet 310, the water delivery unit 340, and the humidification water inlet 211 in sequence.

The water supply switch unit 320 is used for controlling the on-off state of the water storage unit drain port 310 and the humidification water inlet port 211. When the water supply switch unit 320 is turned off, the water storage unit discharge port 310 is not communicated with the humidification water inlet port 211, that is, the liquid in the water storage unit 300 cannot flow into the humidification water tray 213. When the water supply switch unit 320 is turned on, the water storage unit drain port 310 communicates with the humidification water inlet port 211, i.e., the liquid can flow from the water storage unit 300 into the humidification water tray 213. In this embodiment, the water supply switch unit 320 is disposed on the water delivery unit 340, and may be, for example, an electromagnetic valve disposed between the water storage unit drain port 310 and the humidification water inlet port 211. In other alternative embodiments, the water supply switch unit may also be a valve disposed on the water outlet or the humidifying water inlet of the water storage unit.

The ventilation unit 400 communicates the water storage unit 300 with the air outside the humidifying device, and the ventilation unit 400 includes a ventilation pipe 430 and a ventilation valve 440. In the present embodiment, the ventilation unit 400 is used for communicating the water storage unit 300 with the air outside the humidification device, specifically, one end of the ventilation unit 400 is communicated with the water storage unit 300, the other end is communicated with the humidification portion 210 of the humidification device, and the humidification portion 210 is communicated with the air outside the humidification device.

The ventilation pipe 430 is a hollow pipe with two open ends, and connects the water storage unit air vent 360 and the humidifying part 210, and includes a first ventilation hole 410 and a second ventilation hole 420.

The first vent hole 410 is provided at an end of the vent pipe 430 that communicates with the water storage unit vent opening 360.

The second vent 420 is provided at the other end of the vent pipe 430, and communicates with the outside air of the humidifying device. The communication with the outside air of the humidifying device means the communication with the outside air of the humidifying device indirectly or directly. In the present embodiment, the second vent hole is located inside the humidifying portion, specifically, inside the humidifying water tray. In an alternative embodiment, the humidifying portion is directly exposed to the outside air, and the second vent is directly in communication with the outside air of the humidifying device.

In the present embodiment, since the humidifying portion communicates with the outside air of the humidifying device, the air of the humidifying portion communicates with the outside air of the humidifying device.

In other embodiments, the humidifying water tray may be divided into two water trays communicating with each other, wherein the humidifying unit is provided in one of the water trays, and the second vent hole is provided in the other water tray.

When the vent tube 430 is integrated with the water storage unit 300 and is not detachable, the first vent hole 410 and the water storage unit vent hole 360 are the same opening. In other alternative embodiments, the ventilation pipe and the water storage unit can be connected in a detachable mode.

The water storage unit 300 communicates with the interior of the humidifying unit 210 through the water storage unit vent 360, the first vent 410, and the second vent 420. For example, the water storage unit 300 is communicated with the inside of the humidifying part 210, that is, the space inside the humidifying water tray 213, and the air inside the humidifying part 210 may enter the water storage unit 300 through the second vent hole 420, the first vent hole 410, and the water storage unit vent hole 360.

In the attached state, the second ventilation hole 420 is provided above the water shortage detection unit 212 and the humidification water inlet 211. In the embodiment of the present disclosure, the horizontal plane where the second ventilation hole 420 is located is higher than the horizontal planes where the water shortage detection unit 212 and the humidification water inlet 211 are located, respectively.

The following describes the gas and liquid flow and control process between the water storage unit 300 and the humidifying unit 210 in the present embodiment.

When the humidifying device 20 starts operating, the liquid level height of the liquid in the humidifying water tray 213 will be detected by the water shortage detection unit 212. When the water shortage detecting unit 212 detects that the liquid level of the liquid is lower than the height of the water shortage detecting unit 212, that is, the liquid level of the liquid is lower than the second vent 420. The air in the humidifying water tray 213 and the water storage unit 300 are communicated through the second vent hole 420 of the vent pipe 430, and the air pressure in the humidifying water tray 213 is the same as the air pressure in the water storage unit 300.

At this time, the humidifying device 20 controls the water supply switch unit 320 to be turned on, and turns on the water delivery unit 340 to connect the water storage unit drain port 310 and the humidifying water inlet port 211. The liquid in the water storage unit 300 flows into the humidifying water tray 213 through the water storage unit drain port 310, the water delivery unit 340, the water supply switch unit 320, and the humidifying water inlet 211.

The liquid level in the humidifying water tray 213 gradually rises as the liquid increases until the liquid level exceeds the second vent hole 420 of the vent pipe 430. Thus, the second vent 420 seals the liquid in the humidifying water tray 213, and the water storage unit 300 is not communicated with the air in the humidifying water tray 213. At this time, the air pressure in the humidifying water tray 213 is greater than the air pressure in the water storage unit 300. Therefore, even if the water supply switch unit 320 is in the on state, the liquid in the water storage unit 300 does not flow into the humidifying water tray 213 any more.

When the humidifying device 20 starts the humidifying operation, the liquid level of the liquid in the humidifying water tray 213 will gradually decrease as the liquid in the humidifying water tray 213 is atomized or evaporated. The second vent 420 communicates with the space inside the humidifying water tray 213. Since the air pressure in the humidifying water tray 213 is higher than the air pressure in the water storage unit 300, the air in the humidifying water tray 213 enters the air pipe 430 through the second air vent 420 and enters the water storage unit 300 through the first air vent 410. The air pressure in the water storage unit 300 gradually increases, and the air pressure will make the liquid in the water storage unit 300 flow out of the water storage unit 300 again and flow into the humidifying water tray 213. The liquid level in the humidifying water tray 213 rises again until the liquid seals the second vent 420 again.

In this process, the water supply switch unit 320 is kept in the on state all the time without frequent switching, thereby suppressing the reduction in the life span of the water supply switch unit 320 and even the damage thereof due to frequent switching.

Meanwhile, the maximum height of the liquid level of the liquid in the humidifying water tray 213 will be always maintained near the set height, leaving a large space for air circulation. Therefore, the stability of the humidifying efficiency can be well maintained, and the risk of damage to the components (such as a valve or a motor) of the humidifying unit or the air supply device can be reduced while providing a good experience for a user.

In other alternative embodiments, the water storage unit inlet may also be disposed on the top surface of the water storage unit.

The water storage unit inlet 350 is positioned above the water storage unit outlet 310. In this embodiment, the horizontal plane of the water storage unit inlet 350 is higher than the plane of the water storage unit outlet 310, and the projection of the water storage unit inlet 350 on the bottom surface of the water storage unit may or may not coincide with the projection of the water storage unit outlet on the bottom surface of the water storage unit 300.

The full water detection unit 330 is disposed inside the water storage unit 300 and is used for detecting the liquid level of the liquid in the water storage unit 300. In this embodiment, the full water detection unit 330 is disposed on the inner side of the sidewall of the water storage unit 300, and the full water detection unit 330 is disposed above the water storage unit outlet 310 and the full water detection unit 330 is disposed above the water storage unit inlet 350. The full water detection unit 330 is provided below the water storage unit vent 360. In an alternative embodiment, the full water detection unit 330 may also be located below the water storage unit water inlet 350, and the positions of the full water detection unit 330 and the water storage unit water inlet 350 are not limited by the present disclosure. In this embodiment, the full water detecting unit 330 is a float-type water level sensor. In other alternative embodiments, other water level detection methods may be used, such as a capacitive liquid level sensor, as long as the liquid level in the water storage unit can be detected.

When the water shortage detection unit 212 in the humidifying water tray 213 detects that the liquid in the humidifying water tray 213 is not enough to maintain the normal humidifying function, the water supply control switch unit 320 is turned off, and the water storage unit water inlet 350 is turned on, so that the external liquid is injected into the water storage unit 300. When the liquid in the water storage unit 300 increases until the full water detection unit 330 detects that the liquid in the water storage unit 300 reaches the highest liquid level, the water inlet of the water storage unit 350 is controlled to be closed, and the water supply switch unit 320 is turned on.

At this time, the liquid in the water storage unit 300 flows into the humidifying water tray 213 through the water storage unit drain port 310, the water transfer unit 340, and the humidifying water inlet port 211. The liquid level of the liquid in the humidifying water tray 213 rises until the liquid level passes through the second vent holes 420, sealing the water storage unit 300. Thereby, the liquid in the water storage unit 300 stops flowing into the humidifying water tray 213.

Since the water storage unit 300 is further provided with the water storage unit water inlet 350 and the full water detection unit 330, when the liquid in the water storage unit 300 is not enough to maintain the normal operation of the humidification function, the liquid can be injected into the water storage unit 300 through the water storage unit water inlet 350 through a water pipe or the like, thereby realizing automatic water replenishment. Therefore, frequent manual water replenishing of a user can be avoided, meanwhile, due to the fact that automatic water replenishing is achieved, the humidifying device can be installed and applied to a ceiling and the like, indoor space can be saved, and the requirements for miniaturization and invisibility are met.

[ third embodiment ]

The third embodiment of the present invention will be explained below. The same structure as that of the first and second embodiments will not be described again.

The vent unit 400 also includes a vent valve 440.

The vent valve 440 is disposed at a downstream side of the second vent hole 420 to control opening or closing of the second vent hole 420, and the vent valve 440 includes a movable sleeve 500 and a fixed unit 540.

Movable sleeve 500 includes movable member 501, seal 530, and sealing ring 531. In an embodiment of the present disclosure, the active cannula 500 is configured to float on the liquid in the humidifying portion 210. For example, the buoyancy of the liquid to which the movable sleeve 500 is subjected in the humidifying portion 210 is greater than the own weight of the movable sleeve 500.

The movable member 501 is hollow and cylindrical, and can move up and down relative to the second vent hole 420, and the movable member 501 includes an opening 510, a bottom surface 520 opposite to the opening, and a sidewall surrounding the bottom surface 520 and forming the opening 510. In the mounted state, the opening 510 is located on the upstream side of the second vent hole 420, and the bottom surface 520 is located on the opposite side to the opening 510. The end of vent tube 430 adjacent second vent hole 420 extends into the interior of hinge 501. In the embodiment of the present disclosure, the upstream side of the second vent 420 refers to the side of the opening 510 facing the liquid surface of the humidifying water tray 213 located away from the second vent 420. In this embodiment, based on the direction of gravity, the opening 510 is located above the second ventilation hole 420, and the bottom surface 520 is located in the opposite direction to the direction in which the opening 510 faces, i.e., the bottom surface 520 is located below the second ventilation hole 420.

The movable member 501 is hollow cylindrical, and the buoyancy applied to the movable member 501 is greater than the gravity of the movable member 501, so that the movable member can float on the liquid in the humidification water tray. When the liquid level of the liquid in the humidification water tray 213 is higher than the bottom surface of the movable member 501, the movable member 501 floats on the liquid level. In this embodiment, the liquid in the humidifying water tray 213 is water, and the movable member 501 will float on the water surface. In other alternative embodiments, the liquid in the humidifying water tray may be other substances, such as a disinfectant solution or the like.

When the moving member 501 floats on the surface of the liquid, the buoyancy force F applied to the moving member is greater than or equal to the gravity force G applied to the moving member. Due to buoyancy F-liquid density P1-object displacement volume V1-gravity coefficient G, and gravity G-object density P2-object volume V2-gravity coefficient G. And the buoyancy F is more than or equal to the gravity G, namely P1V 1 is more than or equal to P2V 2. Therefore, as long as P1 × y1 is not less than P2 × V2, the movable element 501 can move up and down relative to the second vent hole as the liquid surface of the liquid moves up and down.

In the present embodiment, the movable member is hollow, and therefore can float on the liquid in the humidification water tray. Similarly, the movable member may be made of a material having a density less than that of the liquid in the humidifying water tray, so that the movable member floats on the surface of the liquid.

The sealing member 530 is used to seal the second vent hole 420 and protrudes from the bottom surface 520 toward the opening 510. In this embodiment, the sealing member 530 is a cone, and the outer diameter of the horizontal cross section of the sealing member 530 near the end of the second vent 420 is smaller than the inner diameter of the second vent 420, so that a part of the sealing member 530 extends into the second vent 420 to achieve sealing. Seal 530 includes a seal tip, a seal cross-section. In the installed state, when the sealing member 530 seals the second vent hole 420, the sealing tip is located inside the vent pipe and on the upstream side of the second vent hole 420. The sealing section is a section on the sealing element, and the horizontal sectional area of the sealing section is equal to the area of the second vent hole. In other alternative embodiments, the sealing element may have other shapes, such as a hemispherical structure with an outer diameter smaller than an inner diameter of the second vent hole at the end of the sealing element facing the second vent hole.

The fixing unit 540 connects the ventilation pipe 430 with the movable sleeve 500, and includes a snap 541 and an elastic unit 542.

The engaging piece 541 is fixedly connected to the vent pipe 430, is located on the upstream side of the second vent hole 420 (i.e., on the side of the second vent hole 420 away from the surface of the humidification water tray), and is a flange that protrudes and extends from the outer periphery of the vent pipe 430 to the further outer peripheral side. The outer diameter of the engaging member 541 is smaller than the inner diameter of the movable sleeve 500. That is, the outer peripheral edge of the engaging piece 541 is spaced apart from the inner peripheral side of the side wall of the movable sleeve 500.

The elastic unit 542 is used to connect the engaging member 541 and the movable sleeve 500. In the embodiment of the present disclosure, the connection here means that one end of the elastic unit 542 is connected to the engaging member 541 and the other end is connected to the movable sleeve 500. The height of the elastic unit 542 is greater than the distance between the engaging piece 541 and the second vent 420, that is, the height of the elastic unit 542 is greater than the distance between the engaging piece 541 and the second vent 420 in the direction of gravity. In this embodiment, the elastic unit is a spring. In alternative embodiments, the elastic unit may also be another elastic component with elasticity, such as rubber.

A sealing ring 531 is provided on the sealing member 530 for sealing a gap between the second venting hole 420 and the sealing member 530. The distance between the sealing ring 531 and the sealing tip is smaller than or equal to the distance between the sealing cross section and the sealing tip. In this embodiment, the sealing ring is made of rubber, the outer diameter of the sealing ring is larger than the inner diameter of the second vent hole 420, and the inner diameter of the sealing ring is smaller than the outer diameter of the second vent hole 420. In other alternative embodiments, the sealing ring may be other types of sealing components capable of achieving a sealing effect, such as a sealing ring made of nylon, polyurethane, engineering plastic, and the like.

When the humidifying device 20 starts operating, the liquid level height of the liquid in the humidifying water tray 213 will be detected by the water shortage detection unit 212. When the water shortage detection unit 212 detects that the liquid level is lower than the height of the water shortage detection unit 212, that is, the liquid level is lower than the second vent hole 420 at the vent valve 440.

At this time, since the movable member 501 of the movable sleeve 500 of the vent valve 440 floats on the surface of the liquid in the humidification water tray, the height of the sealing tip of the sealing member 530 provided on the movable member 501 is lowered, and a distance is provided between the sealing member 530 and the second vent hole 420. Accordingly, the air in the humidifying water tray 213 passes through the gap between the sealing member 530 and the second vent hole 420, and is communicated with the air in the water storage unit 300 through the vent pipe 430 and the first vent hole 410, that is, the air pressure in the humidifying water tray 213 is the same as the air pressure in the water storage unit 300. In the embodiment of the present disclosure, the movable member 501 floats in the humidification water tray, for example, the bottom surface of the movable member 501 or a part of the movable member 501 is immersed in the liquid, and the movable member 501 moves along with the liquid level of the liquid in the humidification water tray due to the buoyancy of the liquid.

The liquid level in the humidifying water tray 213 gradually rises as the liquid increases. Since the movable member 501 floats on the liquid surface, it will gradually approach the second vent 420 as the liquid surface rises. Wherein the sealing member 530 is lifted therewith until the sealing member 530 seals the second vent hole 420. At this time, the space of the water storage unit 300 is not communicated with the space of the humidifying water tray 213, and the water storage unit 300 is sealed. Since the humidifying water tray 213 communicates with the air outside the humidifying part 210, the air pressure outside the water storage unit 300 is greater than the air pressure inside the water storage unit 300. At this time, even if the water supply switch unit 320 is in an on state, the liquid in the water storage unit 300 does not flow into the humidifying water tray 213 any more.

When the humidifying device 20 starts the humidifying operation, the liquid level of the liquid in the humidifying water tray 213 will gradually decrease as the liquid in the humidifying water tray 213 is atomized or evaporated. At this time, if the second vent 420 is sealed by the liquid level, a part of the liquid in the humidification water tray 213 may be drawn into the vent tube 430 through the second vent 420 by a capillary action by the air pressure. As the liquid in the humidifying water tray 213 is atomized or evaporated, the liquid level of the liquid drops, and the liquid sucked into the air pipe 430 cannot flow out of the air pipe 430 by the air pressure, so that the water storage unit 300 cannot communicate with the humidifying water tray 213 even if the liquid level of the liquid in the humidifying water tray is lower than the second air hole 420, and therefore, the water in the water storage unit may not flow into the humidifying water tray 213. That is, in the case where the vent valve 440 is not provided, there occurs a problem that the second vent hole is clogged with the liquid.

In this embodiment, since the ventilation unit 400 is provided with the ventilation valve 440 and the second ventilation hole 420 is sealed by a fixing structure such as the sealing member 530, the movable member 501 and the sealing member 530 descend along with the descending of the liquid level, and a certain distance is generated between the sealing member 530 and the second ventilation hole 420. Since the air pressure in the humidifying water tray 213 is higher than the air pressure in the water storage unit 300, the air in the humidifying water tray 213 enters the air pipe through the gap between the sealing member 530 and the second air hole 420, and then enters the water storage unit 300. The air pressure in the water storage unit 300 gradually increases, and the air pressure will make the liquid in the water storage unit 300 flow out of the water storage unit 300 again and flow into the humidifying water tray 213. The liquid level in the humidifying water tray 213 rises again until the sealing member 530 seals the second vent hole 420 again.

Thus, the water storage unit 300 can be prevented from being sealed even when the liquid level in the humidification water tray 213 is lower than the second vent hole 420 due to the occurrence of the capillary phenomenon by providing the vent valve 440.

Meanwhile, the maximum height of the liquid level of the liquid in the humidifying water tray 213 will be always maintained at the height near the movable member, leaving a large space for air circulation.

This can maintain the stability of the humidification efficiency, and reduce the risk of damage to the motor of the humidification unit 214 or the blower, while providing a user with a good experience.

In the embodiment of the present disclosure, since the vent valve 440 includes the elastic unit 542 and the engaging member 541, and the elastic unit 542 and the engaging member 541 connect the vent pipe 430 and the movable member 501, when the liquid in the water storage unit 300 gradually decreases to a level where the liquid cannot be supplied to the humidifying water tray 213, and the liquid level of the liquid in the humidifying water tray decreases or even dries up, the movable sleeve 500 can be connected to the lower end of the vent pipe 430 through the elastic unit 542, so as to avoid the problem that the vent pipe cannot be sealed again when the liquid level rises again due to the movable sleeve 500 dropping to the bottom surface of the humidifying water tray 213.

In the embodiment of the present disclosure, the height of the elastic unit 542 is greater than the distance between the engaging piece 541 and the second vent hole 420. Therefore, when the liquid level drops, the movable element 501 and the sealing element 530 move downward under the action of gravity and the buoyancy of the liquid, and the height of the elastic unit 542 is greater than the distance between the engaging element 541 and the second vent hole 420, so that the movable element 501 and the sealing element 530 can drop to be away from the second vent hole 420 by a certain distance. Thus, it is ensured that the water storage unit 300 and the humidification unit 214 can communicate through the vent pipe 430 when the liquid level in the humidification water tray 213 drops.

Meanwhile, since the outer diameter of the engaging member 541 is smaller than the inner diameter of the movable sleeve 500, when the liquid level in the humidification water tray 213 drops and a certain distance is left between the sealing member 530 and the second vent hole 420, air in the humidification water tray 213 can pass through the gap between the engaging member 541 and the movable sleeve 500, enter the space between the movable member 501 and the engaging member 541, then enter the vent pipe 430 through the gap between the sealing member 530 and the second vent hole 420, and further enter the water storage unit 300. This ensures communication between the water storage unit 300 and the air in the humidifying water tray 213.

In the embodiment of the present disclosure, since the outer diameter of the horizontal section of the upper end of the sealing member 530 is smaller than the inner diameter of the second vent hole 420, when the liquid level in the humidifying water tray 213 rises until the sealing member 530 contacts the vent pipe 430, the sealing tip protrudes into the vent pipe 430 through the second vent hole 420, so that the sealing member 530 can better seal the second vent hole 420.

In the embodiment of the present disclosure, since the sealing member 530 is provided with the sealing ring 531, when the sealing member 530 contacts the vent pipe 430, the sealing ring 530 can further seal the gap between the second vent hole 420 and the sealing member 530, thereby preventing air from being communicated between the sealing member 530 and the second vent hole 420.

The utility model provides a humidifying device, which can realize automatic water replenishing, ensure stable humidifying efficiency and inhibit the damage of humidifying components such as a water supply switch unit.

In another embodiment of the present disclosure, there is also provided an air supply device to which the humidifying device described above is applied, the air supply device including: the humidifier comprises an air inlet formed by an opening for allowing air to enter the air supply device, an air outlet for blowing the air to a target space, and an air supply wind path connected with the air inlet and the air outlet, wherein the humidifier is positioned in the air supply wind path.

The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
