Alternatively, a water tank may be placed at the bottom of the housing 1, and the water flow may be converged into the water tank.

The humidifying mesh assembly 3 can float in the water surface converged at the bottom of the housing 1. While moving towards or away from the fan 2 as the water level rises and falls. The humidifying mesh assembly 3 may comprise a humidifying mesh 31. The height of the humidifying mesh 31 is set to be the maximum height at which the humidifying mesh 31 can spread. Since the bottom of the humidification net 31 is immersed in water, water can be continuously replenished.

Optionally, the humidifying mesh assembly 3 may further comprise a float. The floating part is used for bearing the humidifying net 31 and stably driving the humidifying net component 3 to lift. The float may include a float body 32, and the buoyancy of the float body 32 is set such that the bottom of the humidification mesh 31 is soaked with water. The floating body 32 can be adjusted in volume and material by those skilled in the art according to the weight of the humidifying net assembly 3. As an example, the floating body 32 may be a floating plate, hollow foam, or the like. The adjustment can be carried out by a person skilled in the art according to the actual situation.

Further, in order to stably place the humidifying mesh 31 on the floating body 32, an annular groove 34 having a shape adapted to the humidifying mesh 31 may be opened at the upper end of the floating body 32 such that the humidifying mesh 31 is inserted into the annular groove 34.

Still further, the float part may further include a plurality of rollers 35 and a plurality of support rods corresponding to the number of the plurality of rollers 35. Grooves 36 for placing the above-described rollers 35 and support rods in one-to-one correspondence may be provided at the circumference of the floating body 32. One end of the support rod is connected to the groove 36 and the other end is connected to the roller 35 so that the roller 35 is closely engaged to the inner wall of the housing 1.

In order to improve the smoothness of the relative sliding between the first air guiding pipe 41 and the second air guiding pipe 42, a rail and a ball may be provided between the first air guiding pipe 41 and the second air guiding pipe 42. Although the first air guiding duct 41 is inserted into the second air guiding duct 42 in the drawing, this is not exclusive, and the first air guiding duct 41 may be fitted over the second air guiding duct 42. The selection can be made by those skilled in the art according to the actual situation.

Compared with the implementation mode of a pipeline comprising a telescopic pipe or an organ cover, the implementation mode of the air guide assembly 4 comprising the first air guide pipe 41 and the second air guide pipe 42 can improve the strength of the air guide assembly 4, avoid deformation of the air guide assembly 4 caused by the influence of wind pressure and gas flow, and avoid higher resistance loss.

Further, in order to prevent the dry air from being directly discharged from the gap between the first air guiding duct 41 and the second air guiding duct 42, an annular sealing strip 43 may be disposed at the top end of the second air guiding duct 42 or the bottom end of the first air guiding duct 41. The annular sealing strip 43 may be engaged with the first duct 41 and the second duct 42, or may be disposed at a predetermined distance. Still further, the annular sealing strip 43 may be engaged with the inner wall of the casing 1, so as to further prevent the dry air from directly discharging out of the humidifier from the space between the casing and the first and second air guiding pipes 41 and 42. It should be noted that the preset distance may be 1mm or 2mm, and those skilled in the art may determine the preset distance through repeated trials or experience.

On the other hand, under the dual action of the annular sealing strip 43 and the roller 35 arranged on the floating part, the movement of the humidifying net assembly 3 can be further limited, the fault that the humidifying net assembly 3 is inclined is avoided, and the stability and the reliability of the humidifier are improved.

A liquid level assembly may be provided on the housing 1 to detect a water level. By way of example, the level assembly may include an electro-optical level gauge or an ultrasonic level sensor, disposed above the water surface. The level assembly may also be a load cell. May be provided to the bottom of the housing 1 or to the bottom of the tank as described above. The selection can be made by those skilled in the art according to the actual situation.

Still further, the liquid level assembly may further include a magnet disposed on the second air guiding pipe 42 and a plurality of hall sensors longitudinally disposed on the first air guiding pipe 41 or the case 1. In an operating state, in response to the second air duct 42 driving the magnet to move up and down along with the water level, the height of the magnet can be determined by the hall sensor as the magnet approaches the hall sensors with different heights, and then the height of the water level is determined. Therefore, the control end of the humidifier can conveniently acquire water level information, and water adding operation is further carried out.

A water level mark is provided at the top end of the second air guiding duct 42. A transparent window is provided on the housing 1, and the section of the transparent window is the same as the lifting section of the water level mark. The two sides of the transparent window can be provided with water level scales. The user can acquire the water level height by observing the water level scale where the water level mark is located. It should be noted that the water level mark may be a mark line with a distinct color, a pointer arrow, or the like. Therefore, the user can know the water level height at any time.
