Background

In the prior art, for example, the patent document of China, publication number is CN217633010U, a water cooling fan capable of prompting water change is disclosed, an installation cavity is arranged on the fan, the water tank is in sliding connection with the bottom of the installation cavity, a tact switch is arranged on the fan, which is positioned in the installation cavity, and the tact switch is electrically connected with a timer and an alarm; when the water tank is pushed into the installation cavity, the tact switch can be pressed by the water tank and is connected with a power supply, the timer starts to time counting, and when the accumulated time of the counting reaches the set water changing time, the alarm gives an alarm prompt; when the water tank is pulled out of the installation cavity, the tact switch automatically cuts off the power supply, and the accumulated time of the electric control board is cleared. The water cooling fan capable of prompting water change plays a role of prompting a user to change water for the water tank through the alarm signal at regular time.

In the prior art, the water tank is pushed into the installation cavity until the water tank is in press contact with the tact switch, and the water tank is powered on to supply water. When the water tank is pulled away, the water tank is separated from the tact switch so as to realize power failure. The trigger end of the tact switch is in the form of a spring plate, and the spring plate has a certain stroke, so that when the water tank is in contact with the spring plate at the beginning, the contact of the power supply is realized, and the water tank can be pushed to press the spring plate forwards continuously at the moment, so that the maximum limit of compression of the spring plate is reached. In this process, the propulsion of the tank also has a waterway connection of the output of the tank to the interior of the installation cavity, which requires the tank to be completely propelled into the interior of the installation cavity to completely sealingly engage the output of the tank with the waterway in the interior of the installation cavity. Therefore, when the power on-off factor is considered, the water tank can realize power on only by pressing the contact spring piece. When the water supply problem of the water tank is considered, the water tank is required to be pushed in place to ensure the sealing of the waterway.

Therefore, there is a strong need for a water pump on-off control structure for a cooling fan with a water tank limit to solve the above problems.
