The purification module 200 and the humidification module 100 may be connected by a snap-fit connection, enabling a detachable connection of the purification module 200 and the humidification module 100.

The purification module 200, the humidification module 100 and the power module 300 are detachably connected, so that the purification module 200, the humidification module 100 and the power module 300 are conveniently installed and detached, and further transportation, maintenance or replacement is convenient.

The drive mechanism is located outside the third air duct 305 and mounted to an outer wall or base 306 of the third air duct 305.

The driving mechanism is located outside the third air duct 305 and may be mounted to an outer wall surface or a base 306 of the third air duct 305, so that the driving mechanism does not affect ventilation of the third air duct 305 and does not increase windage.

In addition, the driving mechanism is located outside the third air duct 305 to isolate the driving mechanism from the humidified air flowing through the third air duct 305, so that the humidified air cannot pass through the driving mechanism, the driving mechanism is prevented from being wetted, the working reliability of the driving mechanism is improved, and the service life of the driving mechanism is prolonged.

In some exemplary embodiments, as shown in fig. 12, both the drive component 3 and the transmission mount 5 of the drive mechanism are mounted to the base 306.

Compared with the driving part 3 and the transmission seat 5 of the driving mechanism are both mounted on the outer wall surface of the third air duct 305, the driving part 3 and the transmission seat 5 are both mounted on the base 306, so that resonance of the driving mechanism and the wind wheel motor 304 inside the third air duct 305 can be avoided. The driving part 3 of the driving mechanism is connected with the lifting mechanism 4 through the transmission seat 5, so that the driving force of the driving part 3 is transmitted to the lifting mechanism 4 through the transmission seat 5, and the wet curtain 2 is driven to move.

Embodiment two:

the present embodiment provides a humidifier, which is different from the first embodiment mainly in the lifting mechanism 4.

As shown in fig. 17 and 18, in the present embodiment, the lifting mechanism includes a rotation member and a lifting bracket 42.

As shown in fig. 17, the rotating member includes a turntable 43 and a transmission rod 44, the rotation axis of the turntable 43 extends along the height direction of the water tank 1, a guide table 431 is disposed on the side wall of the turntable 43, the guide table 431 includes a first limiting surface 4311, a guide surface 4313 and a second limiting surface 4312 that are sequentially connected, the first limiting surface 4311 and the second limiting surface 4312 all extend along the circumference of the turntable 43 and are staggered in the circumferential direction of the turntable 43, and an axial space along the axial direction of the turntable 43 is provided between the first limiting surface 4311 and the second limiting surface 4312, so that the guide table 431 is Z-shaped.

One end of the transmission rod 44 is connected with the turntable 43, and the other end is connected with a driving mechanism which is arranged to drive the turntable 43 to rotate.

The wet curtain 2 is mounted to the lifting bracket 42. As shown in fig. 18, the lifting support 42 is provided with a limiting portion 426, and the limiting portion 426 is configured to move along the guide table 431 when the turntable 43 rotates, wherein the humidifying module 100 is in a humidifying state when the limiting portion 426 abuts against the first limiting surface 4311, and the humidifying module 100 is in a non-humidifying state when the limiting portion 426 abuts against the second limiting surface 4312.

In the lifting mechanism, the turntable 43 is connected to the driving mechanism through a transmission rod 44, so that the turntable 43 can rotate around the axis thereof under the drive of the driving mechanism, and the axis of the turntable 43 extends along the height direction (i.e., the up-down direction) of the water tank 1. The turntable 43 is provided with a Z-shaped guide table 431, the Z-shaped guide table 431 comprises a first limiting surface 4311, a second limiting surface 4312 and a guide surface 4313 connected between the first limiting surface 4311 and the second limiting surface 4312, wherein the first limiting surface 4311 and the second limiting surface 4312 extend along the circumferential direction of the turntable 43, and the first limiting surface 4311 and the second limiting surface 4312 can be parallel to each other; the first limiting surface 4311 and the second limiting surface 4312 have an interval (axial interval) in the axial direction of the turntable 43, and the first limiting surface 4311 and the second limiting surface 4312 are arranged in a staggered manner in the circumferential direction of the turntable 43, that is, the projections of the first limiting surface 4311 and the second limiting surface 4312 in the circumferential direction of the turntable 43 do not coincide, so that the first limiting surface 4311 and the second limiting surface 4312 have a circumferential interval therebetween. The first limiting surface 4311 and the second limiting surface 4312 have an axial interval and a circumferential interval, so that the guiding surface 4313 connected between the first limiting surface 4311 and the second limiting surface 4312 is an inclined guiding surface 4313, and two ends of the guiding surface 4313 are in smooth transition connection with the first limiting surface 4311 and the second limiting surface 4312 respectively.

The lifting bracket 42 is provided with a limit part 426 matched with the guide table 431, and the limit part 426 can be propped against the guide table 431; in addition, an axial guiding structure can be arranged between the lifting support 42 and the water tank 1, so that the lifting support 42 can only reciprocate along the axial direction of the turntable 43. Therefore, when the driving part mechanism drives the turntable 43 to rotate through the transmission rod 44, the limiting part 426 can slide along the guiding table 431 and slide from the first limiting surface 4311 to the second limiting surface 4312 through the guiding surface 4313, or slide from the second limiting surface 4312 to the first limiting surface 4311 through the guiding surface 4313. Because the first limiting surface 4311 and the second limiting surface 4312 have an axial interval therebetween, when the limiting portion 426 slides onto the first limiting surface 4311, that is, when the limiting portion 426 abuts against the first limiting surface 4311, the first end (lower end) of the wet curtain 2 may extend below the water line of the water containing cavity 11, and at this time, a portion of the wet curtain 2 is immersed in water, and the humidifying module 100 is in a humidifying state; when the limiting portion 426 slides onto the second limiting surface 4312, that is, the limiting portion 426 abuts against the second limiting surface 4312, the first end (lower end) of the wet curtain 2 can be lifted above the water level line of the water containing cavity 11, and the wet curtain 2 is not soaked in water at this time, so that the wet curtain 2 is prevented from being soaked in water for a long time.

Through the cooperation of the limiting part 426 and the guide table 431 and the axial guide structure between the lifting support 42 and the water tank 1, the rotation motion of the turntable 43 can be converted into the lifting motion of the lifting support 42 so as to drive the wet curtain 2 to move up and down.

As shown in fig. 18, a plurality of guide holes 427 may be provided and spaced apart in the circumferential direction of the lifting support 42; accordingly, the guide posts may be located in the water containing chamber 11, and the guide posts may be provided in plurality and spaced apart along the circumference of the water containing chamber 11. Of course, a guide post may be provided on the lifting bracket 42, and a guide hole may be provided on the water tank 1.

In some exemplary embodiments, as shown in fig. 17, the axial spacing h2 between the first and second limiting surfaces 4311, 4312 is greater than the height difference between the rated water line of the water containing chamber 11 and the bottom wall of the water containing chamber 11.

The axial spacing between the first spacing surface 4311 and the second spacing surface 4312 is h2, when the spacing part 426 is switched from being abutted with the first spacing surface 4311 to being abutted with the second spacing surface 4312, the moving stroke of the lifting support 42 and the wet curtain 2 is equal to h2, so that the moving stroke of the wet curtain 2 is larger than the height difference between the rated water level of the water containing cavity 11 and the bottom wall of the water containing cavity 11, the first end (lower end) of the wet curtain 2 can be lifted to be above the rated water level of the water containing cavity 11 when the humidifying module 100 is in a non-humidifying state, the wet curtain 2 cannot be soaked in water, and long-term soaking of the wet curtain 2 in water is avoided.

In some exemplary embodiments, as shown in fig. 17, the side wall of the turntable 43 is further provided with a first stop surface 4314 and a second stop surface 4315, one end of the first stop surface 4314 is connected to one end of the first stop surface 4311 away from the second stop surface 4312, the other end extends toward the side where the second stop surface 4312 is located along the axial direction of the turntable 43, one end of the second stop surface 4315 is connected to one end of the second stop surface 4312 away from the first stop surface 4311, and the other end extends toward the side away from the first stop surface 4311 along the axial direction of the turntable 43.
