As shown in FIG. 6, the upper portion of the dust screen 420 can be provided with an outwardly extending handle portion 450 for ease of handling by a user.

As shown in fig. 2, the air inlet grille 430 may be disposed at the air inlet 102 to prevent human hands from entering the housing and accidentally touching the impeller 302 of the fan 300 when the housing 100 is opened.

Fig. 8 is a schematic view of the air purifying device 10 shown in fig. 1 when the blower 300 is hidden and the water tank 200 is pulled out to a predetermined position, and fig. 8 hides the air inlet grille 430 and the air outlet grille 410.

In some embodiments, as shown in fig. 1 and 8, the air purification apparatus 10 further includes a water tank 200. The air inlet is located at the rear side of the housing 100, and the front side of the housing 100 is opened to form a mounting opening 103. The water tank 200 is installed in the housing 100 to be pushed and pulled back and forth through the installation opening 103. The water tank 200 is used to contain purified water. In the air cleaning device 10, in a normal state, the water tank 200 is pushed into the inside of the housing 100, as shown in fig. 1. When water needs to be added, the user can pull the water tank 200 outward, as shown in fig. 8. The air cleaning device 10 may have a water washing function, so that the air flowing into the housing 100 is washed by water and then blown into the room, thereby making the air fresher. Alternatively, the air cleaning device 10 has a humidifying function for humidifying the indoor environment with the water in the water tank 200.

The top of the water tank 200 has a catch 230, and the top of the housing 100 has a stopper 120. The air cleaning device 10 is configured to: when the water tank 200 is pulled out forward to the preset position (as shown in fig. 8), the catch 230 is restrained by the stopper 120 so that the water tank 200 cannot be pulled out any more, so as to be stably maintained at the preset position. The restraint of the stopper portion 120 on the catch 230 can be released by an electric or manual operation, etc. to allow the water tank 200 to be continuously pulled out forward, so that the water tank 200 can be conveniently cleaned, etc. Thus, the preset position can be designed reasonably, for example, the preset position is set to be a position where the water tank 200 is pulled out to a half distance, so that a user can add water in the preset position conveniently, the user does not need to worry about that the water tank 200 is pulled out violently to cause follow-up re-installation, and the user does not need to worry about that the water tank 200 is too heavy and cannot be installed in the shell 100 again after the water tank is filled with water, and the user operation is very convenient.

FIG. 9 is a schematic cross-sectional view taken in a plane extending back and forth through the structure shown in FIG. 8; fig. 10 is a schematic structural view of the casing 100 in the air cleaning device 10 shown in fig. 1; fig. 11 is an exploded schematic view of the water tank 200 in the air cleaning device 10 shown in fig. 1; fig. 12 is an enlarged view of fig. 11 at B.

In some embodiments, as shown in fig. 9 to 12, the stopper 120 is formed to protrude downward from the top wall of the housing 100. Accordingly, the catch 230 is a resilient tongue extending forward and backward. The rear end of the clip 230 is connected to the rest of the tank 200, and may be formed as an integral part, for example. The upper surface of the catch 230 has a protrusion 231, and the rear surface of the protrusion 231 is a slope surface 2313 that gradually inclines upward from rear to front. The air cleaning device 10 is configured to:

during the rearward pushing of the water tank 200, the stopper 120 is pressed against the slope 2313 to cause the clip 230 to bend downward, thereby allowing the stopper 120 to pass over the protrusion 231 to allow the water tank 200 to continue to move rearward to the closed position. The slope angle may be 15 ° to 25 ° to facilitate the stopper 120 to pass over the protrusion 231.

When the water tank 200 is pulled out to the predetermined position, the protrusion 231 is stopped at the rear side by the stopper 120, so that the water tank 200 cannot be pulled out continuously, as shown in fig. 8 to 10.

When the front end of the latch 230 is pressed downward (downward from the position of fig. 10), the latch 230 (elastic tongue) is elastically deformed, and the front end is bent downward, so that the protrusion 231 is downwardly separated from the stopper of the stopper 120, thereby allowing the water tank 200 to move forward. Thereafter, the pressing force is released, and the latch 230 returns to the original state (the state of fig. 10 and 12) by its own elasticity. As shown in fig. 12, the rear end of the upper surface of the catch 230 may be provided with a plurality of anti-friction ribs 236 to facilitate pressing by a user.

In the structure of the above embodiment of the present invention, the elastic tongue-shaped buckle 230 of the water tank 200 is matched with the limiting part 120 of the housing 100, so that the water tank 200 can be locked when being pulled out to a preset position, and the resistance can be automatically overcome in the process of moving the water tank 200 backwards and pushing in, manual intervention by a user is not required, the operation of the user is simplified, and the design is very ingenious. When the water tank 200 needs to be completely pulled out, the buckle 230 can be manually pressed to unlock the water tank, which is also convenient.

Referring to fig. 10 and 12, the rear surface 124 of the stopper 120 extends forward and backward from top to bottom, and the front surface 2315 of the protrusion 231 extends backward and backward from bottom to top. Thus, when the front surface 2315 of the protrusion 231 collides with the rear surface 124 of the stopper 120 when the water tank 200 is opened, the force applied to the protrusion 231 by the stopper 120 has a downward component, so that the clip 230 moves downward slightly under the component of force due to the elasticity of the clip 230, thereby providing a certain buffer, reducing noise and improving the reliability of the related components.

The latch 230 is formed with at least one bending part 233 which is bent and protruded upward or downward to enhance elasticity, and the bending part 233 may have a "U" shape or a "V" shape. Referring to fig. 10 and 12, the bent portion 233 is one in number and protrudes downward, and is located at a rear section of the catch 230. Also, the bent portion 233 has a "V" shape. When the front end of the buckle 230 is bent downward, the opening of the bending portion 233 is enlarged, so that the bending is more labor-saving, and the buckle 230 is prevented from being broken.

As shown in fig. 11 and 12, a relief hole 225 penetrating up and down may be formed at the top of the water tank 200 to relieve the catch 230, and the rear end of the catch 230 is connected to the rear end of the relief hole 225.

As shown in fig. 11, the water tank 200 includes a tank body 210 and a block 220 fixed to an upper side of the tank body 210, so that a catch 230 is provided, and the catch 230 is formed on the block 220. The number of the hooks 230 may be two, which are respectively located on the left and right sides of the block 220 and located at the middle position of the water tank 200 in the front-rear direction. Accordingly, the number of the stopper portions 120 is also two. The upper front end of the housing 100 has a cross bar, and two stoppers 120 are disposed on the lower surface of the cross bar.

In some embodiments, as shown in fig. 8 and 11, both lateral side walls of the water tank 200 may be provided with handle grooves 219 formed to be depressed inward, respectively, so that a human hand can catch in to pull out or push in the water tank 200.

Fig. 13 is a schematic structural view of an air conditioner according to an embodiment of the present invention.

As shown in fig. 13, an embodiment of the present invention further provides an air conditioner, which includes the air purification apparatus 10 according to any of the above embodiments.
