[0023] The water tank 200 is connected to the lower side of the shell 100, the water tank 200 is provided with a water storage cavity, and the water tank 200 is used to provide water for the evaporation assembly; the water tank 200 and the shell 100 can be detachably connected through clamping, bolt connection, threaded connection or other suitable connection, so as to facilitate the disassembly of the water tank 200 for cleaning; The evaporation assembly includes an evaporation medium 510 and a water distributor 520 arranged in the evaporation cavity, the evaporation medium 510 can be a honeycomb paper wet film, a high polymer material wet film, a hydrophilic sponge, a stainless steel wire mesh, etc., the evaporation medium 510 is arranged between the first cavity portion 121 and the second cavity portion 122, so that the air flow can pass through the evaporation medium 510 to achieve the purpose of air humidification; the water distributor 520 is arranged on the upper side of the evaporation medium 510, and the water distributor 520 is used to uniformly distribute the water in the water distributor 520 on the upper surface of the evaporation medium 510, so that the water distributed on the upper surface of the evaporation medium 510 can penetrate to the entire evaporation medium 510 under the action of gravity.

[0024] The pumping assembly, with reference to Figure 2 , includes a water pump body 560 and a driver 550, the water pump body 560 has a water suction port, a water discharge port and a power input shaft, rotating the power input shaft can make the water suction port suck water and the water discharge port discharge water, the water pump body 560 is a conventional component in the art, and its specific structure will not be described here.

[0025] The water pump body 560 is used to deliver the water in the water tank 200 to the water distributor 520, and the water pump body 560 is arranged at the bottom of the shell 100, so that even if the water pump body 560 leaks, the leaked water can be directly discharged back to the water tank 200, and will not flow to the electronic parts such as the driver 550.

[0026] The water suction port is provided with a water suction pipe extending downward to the inside bottom of the water tank 200, and the water discharge port is provided with a water discharge pipe extending upward to be connected with the water distributor 520; in normal use, the liquid level in the water tank 200 is below the water pump body 560, so that the power input shaft does not contact water; the driver 550 is arranged in the shell 100 and above the water pump body 560, and the power output shaft of the driver 550 is connected with the power input shaft through a linkage mechanism.

[0027] In use, the driver 550 is controlled to start, and the driver 550 drives the power input shaft of the water pump body 560 through the linkage mechanism, so that the water pump body 560 sucks water in the water tank 200 and delivers it to the water distributor 520, and the water distributor 520 distributes the water to the evaporative medium 510, thereby realizing wetting of the evaporative medium 510; at the same time, the fan is controlled to start, so that the air flowing in from the air inlet 120 is discharged from the air outlet 110 after passing through the evaporative medium 510, thereby achieving the purpose of air humidification. In the present application, the water pump body 560 and the driver 550 are arranged separately, and the driver 550 is arranged above the water pump body 560, so that the water pump body 560 is not connected to electricity; even if the water pump body 560 fails or the seal fails after long-time operation, the leaked water will not flow to the driver 550, thereby keeping water and electricity separated and improving the overall performance.

In the present application, the power input shaft and the second gear 561 can be an integrally formed gear shaft, so that the overall radial dimension of the power input shaft and the second gear 561 is small, the structure of the water pump body 560 is compact, and the problem of too large size of the second gear 561 extending into the water tank 200 and thus requiring a corresponding avoiding space in the water tank 200 is avoided.

[0029] In some embodiments of the present application, the water pump body 560 is a diaphragm pump. The diaphragm pump has stable output flow, which is beneficial to keeping the evaporative medium 510 at an appropriate wetness level, preventing the evaporative medium 510 from being too wet to cause too small air flow, and preventing the evaporative medium 510 from being insufficiently wet to cause insufficient water evaporation; at the same time, the diaphragm pump adopts a static seal design, which has good sealing performance; and moreover, as water evaporates, the water circulating in the water tank 200 and the evaporation cavity will gradually harden, and the diaphragm pump can deliver hard water, which is suitable for the present application.

The axial directions of the driving motor 540 and the centrifugal impeller 530 are both vertical, the driving motor 540 and the centrifugal impeller 530 occupy the middle position of the space between the top cover 300 and the evaporation cavity, so that the exhaust passage 111 is annular and the diameter gradually increases from bottom to top, and the air outlet direction of the centrifugal impeller 530 is along the radial direction thereof, which is matched with the shape of the exhaust passage 111, so as to reduce the air resistance, increase the air volume, and better the air humidifying effect.

[0036] In some embodiments of the present application, the water distributor 520 is annular and groove-shaped, matched with the annular evaporation medium 510, the bottom of the water distributor 520 is provided with a plurality of water distribution holes, so that the water flowing out of the water distribution holes can permeate into the evaporation medium 510; the water distributor 520 is sleeved outside the bottom end of the exhaust passage 111, the funnel-shaped side wall of the exhaust passage 111 gradually increases in diameter from bottom to top, and the bottom end is inserted into the inside of the water distributor 520. In this way, the space in the shell 100 is fully utilized to place the water distributor 520, and the air flow is caused to pass through the evaporation medium 510 rather than passing through the side of the water distributor 520, so as to improve the evaporation efficiency.

[0037] In some embodiments of the present application, the air inlet 120 is provided with a filter. The filter can be a HEPA filter screen. In this way, the present application can also filter harmful dust, pollen and other particulate matters in the air, and play the role of air filtration.
