The second engaging portion 11 may be a protrusion protruding downward from the upper sidewall of the mounting groove 13, or may be a groove recessed upward from the upper sidewall of the mounting groove 13, which is not limited herein. When the first clamping part 31 is clamped with the second clamping part 11, the water tank 20 is locked in the mounting groove 13 of the shell 10; when the first catching portion 31 is separated from the second catching portion 11, the water tank 20 is unlocked.

The actuating member 40 is rotatably mounted on the water tank 20 in various ways, for example, a rotating shaft is disposed on the water tank 20, and a shaft hole for mounting the rotating shaft is disposed on the actuating member 40; or the water tank 20 is provided with a shaft hole 23, and the actuator 40 is provided with a rotating shaft 44 inserted into the shaft hole 23 (as shown in fig. 7 and 8). The actuating member 40 is movably connected to the latch 30, and when the actuating member 40 is pressed, the actuating member 40 can drive the first clamping portion 31 to move downward, so that the first clamping portion 31 is separated from the second clamping portion 11, the water tank 20 is in an unlocked state, and the water tank 20 is conveniently detached.

According to the technical scheme, the water tank 20 is provided with the first guide groove 21 extending along the vertical direction, the lock catch 30 is arranged in the first guide groove 21, and the lock catch 30 can move up and down and has a first installation state of being clamped with the shell 10 and a second state of being separated from the shell 10; the actuating member 40 is rotatably mounted on the water tank 20, and the actuating member 40 is movably connected to the lock catch 30, so that when the actuating member 40 is pressed, the first clamping portion 31 can be driven to switch from the first state to the second state, and thus, the water tank 20 can be quickly detached from the cooling fan 100.

Referring to fig. 4 and 5, in a preferred embodiment, the cooling fan 100 further includes an elastic member 50. The elastic member 50 is disposed in the first guide groove 21, the upper end of the elastic member 50 is connected to the lower end of the latch 30, and the lower end of the elastic member 50 is connected to the first guide groove 21. Specifically, the elastic element 50 may be a spring, an elastic column, a rubber sleeve, an elastic sheet, or the like, and preferably, the elastic element 50 is a spring.

Will water tank 20 pushes in during in the mounting groove 13, hasp 30 receives decurrent extrusion force and compresses tightly elastic component 50 downwards, with water tank 20 push back in the mounting groove 13, hasp 30 rebound under elastic component 50's reset action, at this moment, hasp 30 first joint portion 31 with the second joint portion 11 joint of shell 10 to lock water tank 20 in mounting groove 13.

In order to facilitate pushing the water tank 20 into the mounting groove 13, the first clamping portion 31 has a first guide surface 32 disposed to be inclined downward, the second clamping portion 11 has a second guide surface 12 extending to be inclined downward, and the second guide surface 12 and the first guide surface 32 are inclined in the same direction. Here, the first guide surface 32 and the second guide surface 12 cooperate with each other, so that the pressing force applied to the lock catch 30 during the process of pushing and pulling the water tank 20 can be greatly reduced, the user can push and pull the water tank 20 conveniently, the service life of the lock catch 30 is relatively prolonged, and the quality of the product is effectively improved.

Referring to fig. 7 and 8, the lower end of the lock catch 30 is provided with a second guide groove 36 extending in the vertical direction, the outer side wall of the second guide groove 36 abuts against the inner side wall of the first guide groove 21, and the upper end of the elastic element 50 is accommodated in the second guide groove 36. Thus, the second guide groove 36 provides a good limiting effect for the elastic element 50 to elastically contract in the up-down direction.

Further, in order to better mount the elastic member 50, the bottom of the first guide groove 21 may be provided with a first mounting column 22 (as shown in fig. 3 and 5) for mounting the lower end of the elastic member 50, and/or the top of the second guide groove 36 may be provided with a second mounting column for mounting the upper end of the elastic member 50. Specifically, the elastic member 50 is sleeved on the first mounting post 22 and/or the second mounting post, so that the first mounting post 22 and the second mounting post can not only play a role in mounting the elastic member 50, but also can play a good limiting role in moving the lock catch 30 up and down.

There are various ways for the actuator 40 to be movably connected to the latch 30. For example, in one embodiment, the lock catch 30 is provided with a protrusion extending toward the actuating element 40, and the actuating element 40 is provided with a slot for inserting the protrusion. Of course, it is understood that, in another embodiment, the lock catch 30 is provided with a sliding slot 33 extending along the transverse direction, and one end of the actuating member 40 is inserted into the sliding slot 33 and can slide left and right in the sliding slot 33. Specifically, the actuator 40 includes a hand-held portion 41, a sliding portion 42, and a connecting portion 43 (shown in fig. 8) connecting the hand-held portion 41 and the sliding portion 42, and the sliding portion 42 is inserted into the slide groove 33.

On the basis of the above embodiment, the connecting portion 43 is rotatably connected to the water tank 20. The connection portion 43 and the water tank 20 are rotatably connected in various ways, specifically as follows:

in one mode, referring to fig. 7 and 8, the connecting portion 43 is provided with a rotating shaft 44, and the water tank 20 is provided with a shaft hole 23 for mounting the rotating shaft 44.

In the second mode, the connecting portion 43 is provided with a shaft hole, and the water tank 20 is provided with a rotating shaft adapted to the shaft hole.

When the water tank 20 is pushed into the mounting groove 13, the lock catch 30 is pushed downwards by a downward extrusion force and drives the sliding part 42 to rotate downwards; after the water tank 20 pushes the mounting groove 13, the latch 30 moves upward under the restoring action of the elastic element 50 and drives the sliding part 42 to rotate upward, so that the first clamping part 31 of the latch 30 is clamped with the second clamping part 11 of the housing 10, and the water tank 20 is locked on the housing 10. When pressing right handheld portion 41, sliding part 42 rotates downwards, drives hasp 30 removes downwards, so that first joint portion 31 with the separation of second joint portion 11, thereby the convenience will water tank 20 dismantles.

The sliding portion 42 can slide left and right in the sliding groove 33 and can also rotate vertically in the sliding groove 33, and in order to facilitate the sliding portion 42 to rotate vertically in the sliding groove 33, a first supporting portion 34 abutting against the upper surface of the sliding portion 42 is protruded on the upper side wall of the sliding groove 33, and/or a second supporting portion 35 abutting against the lower surface of the sliding portion 42 is protruded on the lower side wall of the sliding groove 33.
