The installation of the box body 340 on the air duct 110 is facilitated by the installation part 350, and the convenience of the matching installation of the box body 340 and the air duct 110 is improved.

Specifically, the mounting portion 350 is formed with a communication cavity 352, the communication cavity 352 is communicated with the water leakage cavity 310, a plurality of clamping ribs 354 arranged at intervals are formed on an outer wall of the mounting portion 350, and the mounting portion 350 is used for penetrating into the bottom end of the air duct 110, so that the clamping ribs 354 abut against the inner wall of the air duct 110. The stability of the mounting portion 350 abutting against the inner wall of the air duct 110 can be improved by the rib 354, and the stability of the mounting portion 350 mounted on the air duct 110 is further improved.

Further, the size of the cross-section of the mounting portion 350 is equal to the size of the cross-section of the air chute 110. When the installation part 350 is disposed at the bottom of the air duct 110, the installation part 350 can be effectively attached to the inner wall of the air duct 110, so as to prevent a gap from occurring between the installation part 350 and the inner wall of the air duct 110, and further prevent water from flowing into the gap between the installation part 350 and the inner wall of the air duct 110. Meanwhile, the air in the air duct 110 can be prevented from leaking from the gap to influence the air quantity in the air duct 110.

In other embodiments, the mounting portion 350 may also be a fastening structure, and is fastened to the air duct 110 by the fastening structure, so as to communicate the air duct 110 with the water leakage cavity 310.

Of course, in other embodiments, the positioning handle 370 may also be omitted.

Referring to fig. 2, 3 and 6, in one embodiment, the blocking member 400 includes a floating plate 410, the floating plate 410 can cover the water outlet 320, the density of the floating plate 410 is less than that of water, and the floating plate 410 can float in the water leakage cavity 310. Since the density of the floating plate 410 is less than that of water, when water flows back into the water leakage cavity 310, the floating plate 410 floats by the buoyancy of the water, and the water can flow out of the water outlet 320. After the water flows out, the floating plate 410 falls down due to the gravity of the floating plate 410 and covers the water outlet 320, so that the air blown by the fan 200 is prevented from leaking from the water outlet 320, and the water is prevented from flowing into the fan 200.

Specifically, the size of the floating plate 410 is larger than that of the drain port 320, and thus the drain port 320 can be effectively covered with the floating plate 410.

In one embodiment, the cross-sectional dimension of the water leaking cavity 310 is matched with the surface dimension of the floating plate 410, the floating plate 410 is provided with through holes 420 penetrating through two opposite surfaces of the floating plate 410, and the through holes 420 and the water draining port 320 are arranged in a staggered manner. Since the cross-sectional size of the water leakage cavity 310 is matched with the surface size of the floating plate 410, the floating plate 410 can be stably moved in the water leakage cavity 310. Because the through hole 420 and the water outlet 320 are arranged in a staggered manner, when the floating plate 410 covers the water outlet 320, the through hole 420 and the water outlet 320 are not arranged in a superposed manner, so that the through hole 420 is prevented from being communicated with the water outlet 320, and further, the air in the air duct 110 is prevented from leaking from the water outlet 320 through the through hole 420. When the water needs to be drained, the floating plate 410 floats, so that the through hole 420 is communicated with the water outlet 320 through the gap between the floating plate 410 and the bottom wall of the water leaking cavity 310, and the water is conveniently drained.

Specifically, the floating plate 410 is provided with a plurality of through holes 420, and each through hole 420 is disposed in a staggered manner with respect to the water outlet 320. The drainage efficiency can be effectively improved by providing the plurality of through holes 420. In other embodiments, the number of the through holes 420 may be one, so long as the water can be discharged from the drain opening 320 through the through holes 420.

In one embodiment, the blocking member 400 further includes at least two guiding portions 430, the at least two guiding portions 430 are disposed on the sidewall of the floating plate 410 at intervals, and the guiding portions 430 are attached to the sidewall of the water leakage cavity 310 and can move along the sidewall of the water leakage cavity 310. The guide 430 can improve the stability of the floating plate 410 floating in the water leakage cavity 310, and further improve the stability of the floating plate 410 covering the water outlet 320.

In an embodiment, the side wall of the water leakage cavity 310 may further be provided with a guide groove, and the guide portion 430 is disposed in the guide groove in a penetrating manner, so as to improve the stability of the guide portion 430 moving in the water leakage cavity 310 and improve the stability of the floating plate 410 floating in the water leakage cavity 310. In other embodiments, the guide slots may also be omitted.

In the present embodiment, the floating plate 410 is a polygonal plate, and the guiding portion 430 is disposed at a corner of the polygonal plate; the size of the cross section of the water leakage cavity 310 is matched with the size of the floating plate 410. Because the cross sectional dimension of the leakage cavity 310 is matched with the dimension of the floating plate 410, the guide part 430 arranged at the edge of the polygonal plate can be correspondingly arranged at the edge of the side wall of the leakage cavity 310, and the guide part 430 is effectively limited by using the included angle structure formed by two adjacent side walls at the edge, so that the guide effect is provided for the movement of the guide part 430.

Specifically, the floating plate 410 is a quadrilateral plate, the number of the guiding portions 430 is four, and the four guiding portions 430 are respectively disposed at corners of the quadrilateral plate. The leakage cavity 310 is a square cavity, and each guide portion 430 is correspondingly disposed at an edge of the inner wall of the direction cavity.

In one embodiment, a gap is formed between the sidewall of the floating plate 410 and the sidewall of the water leakage cavity 310. Because a gap is formed between the side wall of the floating plate 410 and the side wall of the water leakage cavity 310, the frictional resistance of the side wall of the water leakage cavity 310 to the floating plate 410 can be effectively reduced, the floating of the floating plate 410 is facilitated, and the drainage efficiency is improved.

Specifically, the guide 430 abuts against the sidewall of the water leakage cavity 310, so that a gap is formed between the sidewall of the floating plate 410 and the sidewall of the water leakage cavity 310. The guide portion 430 can improve the floating stability of the floating plate 410, and prevent the floating plate 410 from being inclined in the floating process and affecting the covering of the drain port 320 by the floating plate 410.

In one embodiment, the blocking member 400 further includes a piston 440, the piston 440 is disposed on a side of the floating plate 410 facing the water outlet 320, and the piston 440 can be inserted into the water outlet 320. By inserting the piston 440 into the drain port 320, the sealing performance of the drain port 320 can be effectively improved, and further, the air in the air duct 110 is prevented from leaking from the drain port 320.

Specifically, the size of the cross section of the piston 440 tends to decrease in a direction away from the floating plate 410, and the maximum size of the cross section of the piston 440 is larger than the size of the drain port 320. Since the size of the cross section of the piston 440 tends to decrease in a direction away from the floating plate 410, the piston 440 is conveniently inserted into the drain port 320, and further, since the maximum size of the cross section of the piston 440 is larger than the size of the drain port 320, the piston 440 is convenient to effectively cover the drain port 320, and the sealing performance of the drain port 320 is improved. In this embodiment, the piston 440 has a conical configuration. In other embodiments, the piston 440 may have other configurations.

In one embodiment, the piston 440 is inserted into the water outlet 320, and a gap is formed between the floating plate 410 and the bottom wall of the water leaking cavity 310. Specifically, the maximum size of the cross section of the piston 440 is larger than the size of the water discharge port 320, and therefore, when the piston 440 is inserted into the water discharge port 320, the piston 440 cannot be completely inserted into the water discharge port 320, and the floating plate 410 passes through a gap between the piston 440 and the bottom wall of the water leakage cavity 310.

Since the drain port 320 is sealed by the piston 440, the wind blown by the fan 200 is prevented from leaking through the drain port 320. When the water flows backward, the water can flow into the gap between the floating plate 410 and the bottom wall of the water leaking chamber 310 through the through holes 420 of the floating plate 410. When the gap is filled with water, the floating plate 410 can be floated up so that the piston 440 is separated from the drain port 320 and the water can be discharged through the drain port 320. Through the clearance between the floating plate 410 and the bottom wall of the water leakage cavity 310, the floating plate 410 can float conveniently, and the drainage efficiency is improved. In other embodiments, the floating plate 410 may be attached to the bottom wall of the water leaking chamber 310.

Specifically, an air outlet is formed at the top end of the air duct 110, and the air outlet is communicated with the water tank 100. The air in the air duct 110 is blown out through the air outlet, so that the water mist in the water tank 100 can be conveniently blown out.

In other embodiments, an atomizing chamber is formed in the water tank 100, the atomizing element 500 is disposed in the atomizing chamber, the atomizing chamber is communicated with the air duct 110, the water mist generated in the atomizing chamber can enter the air duct 110, and the fan 200 blows out the water mist through an air outlet on the air duct 110.

In an embodiment, the air duct 110 is integrally formed in the water tank 100, so that the stability of the air duct 110 in the water tank 100 can be improved, and the sealing performance between the air duct 110 and the water tank 100 can be improved. In other embodiments, the air duct 110 may be disposed in the water tank 100 by welding, clamping, or the like.
