A water pump reset structure for cooling fan

Abstract

The invention discloses a water pump resetting structure for a cooling fan, which includes a machine body. A water tank installation cavity suitable for push-pull installation of the water tank is provided at the lower part of the body. A connecting seat is installed on the inner side of the body above the water tank installation cavity, and the connecting seat is rotatably connected to a water pump. A bracket, one end of the water pump bracket is extended with a support arm, the water pump assembly is installed on the support arm, the other end of the water pump bracket is extended with a counterweight seat, and a counterweight block is installed on the counterweight seat, and the weight of the counterweight block is greater than that of the water pump The weight of the components, the structure is simplified to the maximum through the seesaw principle, which makes the mechanical cooperation simpler and more reliable during operation, avoiding the rust of the elastic elements caused by the water pump bracket due to long-term contact with water vapor, resulting in failure of the reset structure, and due to the failure of the spare parts Reduction leads to lower overall costs and higher profit margins.

Description

technical field [0001] The invention relates to the field of cooling fans, in particular to a water pump reset structure for cooling fans. Background technique [0002] At present, the cooling fan is a new type of product after the electric fan. It can not only supply air, heat, purify, but also humidify, and cool down through the evaporation of water, so that the cooling effect can reach the comfort level of the air conditioner, and consumes less energy. It can be small, so it is loved by people. [0003] However, this type of product requires the user to add water or replace the ice crystal box regularly, and the water tank and water curtain need to be cleaned after a period of use. It needs to be used at the bottom of the water tank, so when the water tank is pulled out, the water pump needs to be lifted first, or the water pump should be lifted while pulling out to avoid damage to the water pump structure. [0004] The published Chinese patent 201210224213.3 has provid...

AI Technical Summary

Problems solved by technology

[0004] The published Chinese patent 201210224213.3 has provided a better structural method to solve the problem that the water pump sinks into the bottom of the water tank or is lifted when the water tank is pushed in or pulled out, but the reset structure of the patent structure adopts elastic elements ( Including coil spring, torsion spring or shrapnel), the elastic element of this material is made of iron casting. When the elastic element is exposed to the water vapor generated by the cooling fan and the moisture in the water tank for a long time, it is easy to rust the elastic element and cause the elasticity to decay. It is easy to cause the suspension of the water pump bracket to be lower than the height of the water tank, so that the water tank will collide with the water pump when it is pushed in next time, causing damage to the reset mechanism of the water pump or the water tank. It is easy to cause the force of the elastic element of the water pump reset mechanism to be greater than the weight of the water tank, so that the water tank is pushed out of the water tank installation cavity during use
