The evaporative humidifier generally comprises a fan, a filter screen and a water tank, wherein the filter screen is partially soaked in water, and air flow is guided by the fan to pass through the filter screen for absorbing moisture and then is blown out, so that the air flow carries water vapor and is blown out of the humidifier, and the purpose of humidifying air is achieved. In the related art, the filter screen is fixed in the bottom of water tank, and the filter screen extends to the top of water tank by the bottom of water tank all the time, and the height of filter screen is higher, because the filter screen needs periodic replacement, is a expendable accessory, and the higher the filter screen, the more processing material that the filter screen needs, has increased the processing cost and the use cost of humidifier in the intangible.

In view of the above, the embodiment of the application provides a humidifying device, through setting up float and elastic component to drive the filter piece and remove under the buoyancy through the float and the elastic component's elasticity effect, and then make the filter piece change along with the liquid level of humidification liquid and go up and down for the water tank, and then can reduce the size of filter piece along the direction of height, thereby reduce the processing cost and the use cost of filter piece.

Specific embodiments of a humidifying device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 6, the humidifying device provided herein includes a humidifying main body 100, a water tank 200, a filter assembly 300 and a lifting assembly 400, the water tank 200 having a receiving chamber 210 for receiving humidifying liquid, the filter assembly 300 including a filter member 310 and a float 320, the humidifying main body 100 being in communication with the receiving chamber 210, the filter member 310 and the float 320 being disposed in the receiving chamber 210.

In this application, the humidification host 100 is used to drive the flow of air, the water tank 200 is used to store humidification liquid, the filter assembly 300 is used to absorb humidification liquid in the water tank 200 and form a large evaporation surface, and the lifting assembly 400 is used to drive the filter assembly to lift.

The humidifying device can be further provided with a base 500, the base 500 is used for bearing the water tank 200, and the base 500 has a large contact surface to stabilize the humidifying device.

Specifically, the filter assembly 300 may include a filter 310 and a float 320, where the filter 310 is configured to absorb the humidifying liquid and drive air outside the humidifier into the humidifier under the wind force of the humidifying host 100, so that the air takes away the humidifying liquid evaporating the surface of the filter 310, thereby increasing the humidity of the surrounding environment.

It will be appreciated that since the filter member 310 can absorb the humidifying liquid, the filter member 310 has a relatively heavy weight after absorbing the humidifying liquid, the bottom end of the filter member 310 contacts the bottom wall of the receiving chamber 210, and the filter member 310 cannot float on the humidifying liquid, and thus the float 320 is provided on the filter member 310 such that the humidifying liquid provides buoyancy to the filter member 310 when the float 320 contacts the humidifying liquid.

The lifting assembly 400 includes an elastic member 410 and a telescopic bracket 420, the telescopic bracket 420 includes a first bracket 421 and a second bracket 422, the second bracket 422 and the accommodating cavity 210 are relatively fixed, the first bracket 421 is located below the second bracket 422 and is disposed at the upper end of the filtering assembly 300, the elastic member 410 is connected between the first bracket 421 and the second bracket 422, and the elastic direction of the elastic member 410 is pointed to the first bracket 421 by the second bracket 422. The filter assembly 300 is configured to move the filter member 310 under the buoyancy of the float 320 and the elastic force of the elastic member 410 such that the height of the filter member 310 is changed as the level of the humidifying liquid is raised and lowered.

The end of the filter element 310 facing the first support 421 may abut against the first support 421, or may be fixedly connected with the first support 421, for example, the end of the filter element 310 facing the first support 421 is bonded to the first support 421.

That is, the elastic force of the elastic member 410 to the filter member 310 is downward, the buoyancy of the humidifying liquid to the filter member 310 is upward, the buoyancy of the humidifying liquid to the filter member 310 is changed along with the change of the liquid level of the humidifying liquid, the deformation of the elastic member 410 is correspondingly changed along with the change of the buoyancy, when the buoyancy and the elastic force reach balance, the filter member 310 will not continuously lift, and if the liquid level of the humidifying liquid continuously changes, the height of the filter member 310 will synchronously lift along with the liquid level of the humidifying liquid.

When the level of the humidified fluid is lowered, the filter 310 is lowered with respect to the water tank 200 by the resultant force of the buoyancy of the float 320 and the elastic force of the elastic member 410. When the level of the humidifying liquid rises, the filter member 310 rises with respect to the water tank 200 by the resultant force of the buoyancy of the float 320 and the elastic force of the elastic member 410, so that the lower portion of the filter member 310 sufficiently contacts the humidifying liquid and an ineffective area of the filter member 310 immersed in the humidifying liquid is reduced.

Therefore, the dimension of the filter 310 in the height direction can be set smaller, and thus the cost of the filter 310 can be saved. Even though the dimension of the filter member 310 in the height direction is relatively small, the filter member 310 may have a large evaporation surface area without affecting the effective use area of the filter member 310.

Compared with the mode that the bottom end of the filter screen contacts the bottom wall of the water tank 200 and the filter screen extends from the bottom of the water tank 200 to the top of the water tank 200 in the related art, the humidifying device in the embodiment of the application is provided with the lifting assembly 400 to drive the filter element 310 to lift relative to the water tank 200, so that the filter element 310 does not need to extend from the bottom of the water tank 200 to the top of the water tank 200 uniformly, the dimension of the filter element 310 in the height direction can be shortened, the height of at least one third of the filter element 310 can be kept immersed in the humidifying liquid no matter the liquid level of the humidifying liquid is high, the filter element 310 can be ensured to fully absorb the humidifying liquid, and the ineffective area of the filter element 310 immersed in the humidifying liquid can be reduced.

The humidifying device provided by the embodiment of the application comprises a humidifying host 100, a water tank 200, a filter assembly 300 and a lifting assembly 400, wherein the filter assembly 300 comprises a filter element 310 and a floater 320, the lifting assembly 400 comprises an elastic element 410 and a telescopic support 420, the telescopic support 420 comprises a first support 421 and a second support 422, the floater 320 is arranged on the filter element 310 to enable humidifying liquid to provide larger buoyancy force for the filter element 310, the second support 422 is used for fixing the telescopic support 420, the first support 421 is used for being connected with the filter element 310, the telescopic support 420 is formed together with the second support 422, the elastic element 410 is used for providing elastic force to drive the first support 421 to move relative to the second support 422, and the filter element 310 is driven to lift under the combined action of the buoyancy force and the elastic force, so that the bottom of the filter element 310 can always keep contact with the humidifying liquid when the liquid level of the humidifying liquid changes. In this way, the dimension of the filter 310 in the height direction may be set smaller to save the cost of the filter 310, thereby saving the cost of the humidifying device.

Referring to fig. 5 and 6, in some embodiments, the telescoping support 420 defines an air flow path 423 that communicates through the interior of the filter element 310 and the humidifying host 100.

Thus, when air flows, the air penetrates through the filter 310 and takes the humidifying liquid on the surface of the filter 310, and then the air carrying the humidifying liquid flows to the outside of the humidifying device through the inside of the filter 310, the air flow passage 423 and the humidifying host 100 in order. In this way, the flow direction of the air can be limited, so that the filter element 310 is ensured to have a larger air outlet surface, so that the air contacts with the humidifying liquid on the surface of the filter element 310 as much as possible, and the humidifying effect of the humidifying device is improved.

In one possible implementation, the first bracket 421 and the second bracket 422 are slidably connected in a vertical direction. In this way, the second support 422 may be fixed to the water tank 200, and the first support 421 may reciprocate in a vertical direction with respect to the second support 422 under the elastic force of the elastic member 410, thereby providing the elastic force to the filter 310.

In some embodiments, the float 320 is ring-shaped, and the float 320 is sleeved on the end of the filter 310 away from the humidifying main machine 100.

That is, the filter element 310 is cylindrical, so that the filter element 310 has a larger surface area with the same volume, and the corresponding float 320 may be annular, and the float 320 is disposed around the outer sidewall of the filter element 310, so that after contacting with the humidifying liquid, the humidifying liquid exerts a uniform buoyancy on the end surface of the float 320, thereby providing the filter element 310 with a uniformly distributed buoyancy.

In some embodiments, the first bracket 421 is sleeved on the second bracket 422, the filter 310 is fixedly connected to the first bracket 421, and the second bracket 422 abuts against the water tank 200.

In this way, the second support 422 can be fixed relative to the accommodating cavity 210, the first support 421 can move relative to the second support 422 along the vertical direction, and the fixed connection between the filter element 310 and the first support 421 can enable the first support 421 and the filter assembly 300 to form a whole, the elastic force is applied to the first support 421, the buoyancy force is applied to the float 320, and then the first support 421 and the filter assembly 300 are lifted synchronously.

Referring to fig. 5 to 8, in the embodiment, the first support 421 includes a first sleeve 4211, the second support 422 includes a second sleeve 4221, the first sleeve 4211 is sleeved on the second sleeve 4221, and the first sleeve 4211 and the second sleeve 4221 jointly enclose an airflow channel 423.

In this way, the first sleeve 4211 is sleeved on the second sleeve 4221, so that the first support 421 and the second support 422 are slidably connected, and an air flow channel 423 through which air flows is formed inside the first support 421 and the second support 422, so that the air passes through the filter 310 and carries humidification liquid, and flows along the air channel and the humidification host 100 in sequence.

Referring to fig. 2 and 8, in some embodiments, the second support 422 further includes an abutting portion 4222, the abutting portion 4222 is connected to an end of the second sleeve 4221 near the humidifying host machine 100, and opposite sides of the abutting portion 4222 abut against opposite ends of the water tank 200 and the humidifying host machine 100, respectively.

That is, the surface of the abutting portion 4222 facing away from the humidification host 100 abuts against the end of the water tank 200 facing the humidification host 100, and the surface of the abutting portion 4222 facing the humidification host 100 abuts against the end of the water tank 200 facing the humidification host 100, so that the abutting portion 4222 can close the gap between the second support 422 and the humidification host 100.

It should be understood that if there is a larger gap between the second support 422 and the humidifying host 100, air entering the accommodating chamber 210 from outside will flow directly to the humidifying host 100 through the gap between the second support 422 and the humidifying host 100, and will not flow through the filter member 310 located under the second support 422, so that less humidifying liquid is carried in the flowing air, and thus the humidifying effect of the humidifying device is poor.

Referring to fig. 2 and 8 to 10, in one possible implementation, the humidifying main unit 100 includes a main unit housing 110, a sealing portion 111 is provided at an end of the main unit housing 110 facing the water tank 200, and the sealing portion 111 abuts against the abutting portion 4222 to seal a gap between the second support 422 and the main unit housing 110.

By this arrangement, the sealing effect between the second support 422 and the main body housing 110 can be improved, and thus air is prevented from flowing through the gap between the second support 422 and the main body housing 110.

Referring to fig. 2 and 7, in some embodiments, the first support 421 further includes a connecting portion 4212, the connecting portion 4212 is connected to an end of the first sleeve 4211 facing away from the humidifying device 100, and the filter member 310 is fixedly connected to the connecting portion 4212. In this way, the filter member 310 may be fixedly connected to an end of the first sleeve 4211 facing away from the humidifying mainframe 100, and the first bracket 421 and the filter member 310 may be lifted and lowered synchronously.

Wherein the filter 310 may be bonded to the connection portion 4212.

In some embodiments, the connection 4212 is an annular flange surrounding an end of the first sleeve 4211 facing away from the humidifying host 100. So that the connection portion 4212 is surrounded on the end surface and the side wall of the filter member 310 facing the end of the humidifying main machine 100, to increase the bonding area of the first bracket 421 and the filter member 310. Referring to fig. 7 and 8, in one possible implementation, the inner side wall of the first sleeve 4211 is provided with a guide rib 4213, the outer side wall of the second sleeve 4221 is provided with a guide groove 4223, the guide rib 4213 and the guide groove 4223 extend along the axial direction of the first sleeve 4211, and the guide rib 4213 is slidably connected to the guide groove 4223.
