A water curtain device that can automatically adjust the overflow speed

Abstract

The invention relates to a water curtain device capable of automatically adjusting overflow speed. The water curtain device comprises a frame chamber (3), a water tank (4) and a curtain core (2) located in the frame chamber (3), and the water tank (4) comprises a tank wall (6) and a tank cavity (8). The water curtain device is characterized in that multiple channels are formed in the tank wall (6) and communicated with the frame chamber (3), multiple overflow lips used for overflowing stored water and guiding the stored water into the multiple channels are formed in the tank wall (6), and the height of the overflow lips is larger than the width of the overflow lips. When the water curtain device is used, as the channels and the tank cavity are staggered, water can be fed into the tank cavity at any position above the water tank, and it is avoided that the impact force of water affects the flow rate of falling flowing water of part of the channels; when reaching the lower ends of all the overflow lips, the fed water of the tank cavity will synchronously overflow from the overflow lips and is guided into all the channels, and the flowing water can fall synchronously; when the speed of the fed water is increased, the fed water at the water level rising position will automatically overflow from the upper ends of all the overflow lips and is guided into all the channels, and therefore overflow speed is automatically increased.

Description

technical field [0001] The invention relates to the field of air coolers, in particular to a water curtain device capable of automatically adjusting the overflow speed, and the water curtain device is one of the components of the air cooler. [0002] The common name of air cooler also includes cooling fan, evaporative air cooler, etc.; the common name of water curtain device also includes wet curtain device, etc. Background technique [0003] The working principle of the air cooler is different from that of the air conditioner. It mainly realizes the cooling of the air through the principle of water absorbing heat during the evaporation process. [0004] The main components of the air cooler include a motor, a water curtain device, and a water pump. The water pump circulates water to the water tank provided on the upper end of the water curtain device to play a role in continuous water supply. On the curtain core provided at the lower end of the curtain device, the falling ...

Problems solved by technology

[0005] However, when the existing air cooler generally feeds water to the water tank at the upper end of the water curtain device, it mainly supplies water directly to the water tank through a water delivery port. The falling water supply speed of nearby passages is greater than that of other passages falling water supply speed, which finally leads to a large difference in the amount of water falling on the curtain core, which affects the cooling effect

[0006] In addition, the channel near the water delivery port will get the water supply first, so the channel near the water delivery port will drop the water supply before the channels at other positions, which will also cause some parts of the water tank to fall into the water or not to fall into the water, which will affect the cooling effect

[0007] In addition, when the speed or demand of water supply changes, especially when it increases, if the retained water supply does not fall from the channel in time, the water supply in the tank may not flow to the curtain core according to the set route, thus affecting the cooling effect
