Description

Technical Field

[0001] The present application relates to the technical field of air conditioning equipment, and in particular to a cooling fan. Background Art

[0002] Cooling fan, also known as environmentally friendly air conditioner, water-cooled air conditioner, air conditioner, etc., is a popular cooling item in modern summer. It uses the principle of natural cold wind to take away the heat in the air through evaporation, thereby reducing the air temperature and providing people with cool cold air.

[0003] The cooling fan mainly includes evaporative filter, fan, water circulation system and controller. Among them, the evaporative filter is the key component of the cooling fan, which is used to evaporate water and absorb heat; the fan provides wind power to blow out the air after cooling through the evaporative filter; the water circulation system includes components such as water tank and water pump, which are used to provide water to the evaporative filter and maintain water circulation; the controller is used to control the speed of the fan and other functions of the cooling fan. The cooling fan has many advantages such as energy saving and environmental protection, low price, easy to move and simple installation. Therefore, it is widely used for local cooling in small areas such as bedrooms, study rooms, offices, etc.

[0004] At present, the water tank of the cooling fan is usually an integrated structure or a pull-out structure. These two design methods make the structure of the cooling fan relatively complex, and also require a separate space specifically for accommodating the water tank, which increases the complexity and manufacturing cost of the production process. In addition, when the cooling fan is idle, it is also quite inconvenient to store the water tank. If the water tank is stored inside the device for a long time, bacteria may breed, posing a potential threat to the hygiene of the product.

[0005] Therefore, this field needs a new technical solution to solve the above problems. Summary of the invention

[0006] In order to solve or improve to a certain extent the technical problem of inconvenient water tank storage of a cooling fan in the prior art, the present invention provides a cooling fan. The cooling fan comprises: a body, on which a slide groove extending in a vertical direction is provided; a water tank, the water tank having a working position located at the bottom of the body and a storage position inverted on the top of the body; and a plug-in board, the plug-in board can be movably arranged in the slide groove, the plug-in board is configured to be connected to the water tank to fix the water tank at the working position, and can be detached from the water tank to allow the water tank to be switched to the storage position.

[0007] It can be understood by those skilled in the art that the cooling fan of the present invention comprises a body, a water tank and a plug-in board. A chute extending in the vertical direction is provided on the body. The water tank has a working position located at the bottom of the body and a storage position inverted on the top of the body. The plug-in board can be movably arranged in the chute, wherein when the plug-in board is connected to the water tank, the water tank can be fixed at the working position; when the plug-in board is separated from the water tank, the water tank can be allowed to switch to the storage position. Therefore, the cooling fan of the present invention can adjust the position of the water tank according to actual needs to realize the conversion of the water tank between the working position and the storage position. In this way, not only can the normal use of the cooling fan be realized, but also the water tank can be conveniently inverted on the top of the body when it is idle, thereby reducing the occupied space, avoiding the residual water in the water tank to breed bacteria and produce odor, and facilitating storage. In addition, the plug-in board arranged slidably can not only conveniently fix and unlock the water tank, but also has a long service life, small space occupation, and is convenient for disassembly, installation, maintenance and replacement.

[0008] In the preferred technical solution of the cooling fan, a partition is provided at the bottom of the body, the partition includes a partition body and a circumferential wall formed at the circumferential edge of the partition body, wherein a through hole is provided on the partition body to allow the plug-in board to pass through. The provision of the partition can isolate the internal components of the body (such as the evaporation filter, fan, water pump and controller, etc.) from the water tank to play a protective role. In addition, a through hole is provided on the partition body of the partition to allow the plug-in board to pass through, so that the plug-in board and the water tank can be easily fixed and unlocked.

[0009] In the preferred technical solution of the cooling fan, the plug board includes a plug board body slidably arranged in the slide slot, a clamping block extending vertically outward is provided on the plug board body, and a clamping hole allowing the clamping block to be inserted therein is provided on the circumferential wall. The cooperation between the clamping block and the clamping hole can increase the reliability and stability of the connection between the plug board and the partition.

Alternatively, the shape and number of the anti-skid protrusions 1421 can also be adjusted according to actual needs.

[0045] like Figure 1 and Figure 4 As shown, when the cooling fan 100 of the present invention is needed, the water tank 130 can be installed at the working position at the bottom of the body 110. The specific installation operation can refer to the following steps: First, the water tank 130 is placed stably on the ground or other suitable support surface, and it is ensured that the opening of the water tank 130 faces upward. Then, the body 110 and the water tank 130 are aligned in the vertical direction, and it is ensured that the partition 120 of the body 110 faces the water tank 130. Then, the plug-in board 140 on the first side wall 1111 and the second side wall 1112 of the body 110 are respectively passed through the corresponding first through hole 12111 and the second through hole 12112 on the partition 120, so that the plug-in board body 141 of the plug-in board 140 is respectively inserted into the corresponding plug-in slot 1321 on the water tank 130. Continue to control the plug board 140 to slide downward until the clamping block 1411 on the plug board body 141 is inserted into the corresponding clamping hole 1221 on the partition 120, and hear or feel the feedback sound of successful clamping, which means that the water tank 130 is installed in place.

[0046] like Figure 2 and Figure 3As shown, when the cooling fan 100 of the present invention is not needed, the water tank 130 can be disassembled and converted to a storage position inverted on the top of the body 110. The specific disassembly and storage operations can refer to the following steps: First, use both hands to act on the gripping plates 142 of the plug-in board 140 on both sides of the body 110 at the same time, slide the plug-in board 140 upward, so that the plug-in board body 141 is completely disengaged from the plug-in slot 1321 on the water tank 130. Next, lift the body 110 upward to separate the body 110 and the water tank 130. Then, pour out the remaining accumulated water in the water tank 130, and turn the water tank 130 downward and steadily inverted on the top of the body 110, so that the water tank 130 can be stored quickly, conveniently and efficiently.
