Abstract
Description
Technical Field
[0001] The utility model relates to a cooling fan. Background Art
[0002] Air coolers, also known as cooling fans, are devices that transport cold air outward. Currently, there are two types of cold sources. One is that the air cooler has its own refrigeration device, which is relatively heavy, has high processing requirements, and consumes a lot of electricity. The other cold source uses other refrigeration equipment (such as a refrigerator) to cool water first, or uses ice bags to soak the wet curtain with pre-cooled water, and the wind from the fan blows the wet curtain to achieve the purpose of delivering cold air. The device is simple and low in cost. This patent is aimed at the latter type of air cooler. In the existing air cooler structure, the water in the water tank is generally pumped to the wet curtain by a power mechanism, and a power mechanism needs to be installed inside the air cooler, which is more complicated in structure. Utility Model Content
[0003] In the conventional medium air cooler structure, it is often necessary to additionally install a power mechanism inside to pump water in the water tank to the wet curtain. To address the above shortcomings, the utility model provides an air cooler.
[0004] To achieve the above-mentioned purpose, the utility model provides an air cooler, comprising an upper water tank and a lower water tank, the upper water tank and the lower water tank are separated by a partition, the rear part of the lower water tank is processed with an upper folded edge of the lower water tank, the upper folded edge of the lower water tank is processed with an embedded groove for fixing a water curtain, the bottom of the water curtain reaches the lower water tank, a hose connects the upper water tank and the lower water tank, a swing arm and a pressure rod are installed at the lower water tank through a bracket, and the fan is located on the left side.
[0005] As a further improvement of the utility model, a through hole is processed at the partition for the hose to pass through, and the through hole is sealed with a sealant.
[0006] As a further improvement of the utility model, a filling port is processed on the upper water tank, and a movable cross piece is placed at the filling port.
[0007] As a further improvement of the utility model, a hose clamp is installed on the bottom plate of the lower water tank for positioning the hose, and a notch is processed on the bottom plate of the lower water tank, and the notch is located below the hose.
[0008] As a further improvement of the utility model, the bracket is fixed under the partition, and the bracket can rotatably fix the swing rod through a transverse pin. One end of the swing rod is vertically connected to the pressure rod, and the other end of the swing rod is connected to the float.
[0009] The beneficial effects of the utility model are:
[0010] 1. The wet curtain directly enters the lower water tank and contacts with the cooled water. It has a simple structure and can achieve the effect of delivering cold air.
[0011] 2. The buoyancy of water is used to control the float, so that the pressure rod directly squeezes the surface of the hose to achieve the purpose of controlling the water flow. The device is simple and does not require external power or opening and closing of the valve. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0016] like Figure 1 As shown, the utility model discloses a cooling fan, comprising an upper water tank 1 and a lower water tank 3. A filling port 11 is formed on the upper water tank 1, and a movable crossbar 12 is placed at the filling port 11. When an ice pack needs to be placed, the crossbar is laid out and the ice pack is placed on top. The upper water tank 1 and the lower water tank 3 are separated by a partition 2, and a through hole 21 is formed at the partition 2 for the hose 9 to pass through. The through hole 21 is sealed with a sealant. The rear part of the lower water tank 3 is processed with the upper folding edge 32 of the lower water tank. The upper folding edge 32 of the lower water tank is processed with an embedded groove 33 for fixing the water curtain 5. The lower part of the water curtain 5 reaches the lower water tank 3 to ensure that the water curtain is in contact with cold water. The hose 9 connects the upper water tank 1 and the lower water tank 3. The hose clamp 10 is installed on the lower water tank bottom plate 31 of the lower water tank 3 to position the hose 9. The lower water tank bottom plate 31 is processed with a notch 311. The notch 311 is located below the hose 9. The processing of the notch is to better squeeze the hose and achieve a better interception effect. The lower water tank 3 is installed with a swing rod 7 and a pressure rod 71 through a bracket 8. The bracket 8 is fixed under the partition 2. The bracket 8 can rotatably fix the swing rod 7 through a transverse pin 81. One end of the swing rod 7 is vertically connected to the pressure rod 71, and the other end of the swing rod 7 is connected to the float 4. The fan 6 is located on the left.
[0017] The wet curtain directly enters the lower water tank and contacts the cooled water. The structure is simple and can achieve the effect of sending cold air. The float is controlled by the buoyancy of water, so that the pressure rod directly squeezes the surface of the hose to achieve the purpose of controlling the water flow. The device is simple and does not require external power or valve opening and closing.
[0018] In order to facilitate the understanding of the present invention, the following description is given in conjunction with the accompanying drawings during specific use;
[0019] When in use, add cold water to the upper water tank. When there is no water in the lower water tank, the float does not touch the water, the float goes down, the hose is unobstructed, and the water in the upper water tank enters the lower water tank. When the water level in the lower water tank is certain, the float floats up, and the pressure rod is pushed down through the swing rod to squeeze the hose, and the water is cut off. Turn on the fan, the lower part of the water curtain contacts the cold water, and the cold water is transported to the high part of the water curtain through the self-priming of the water curtain. The fan transports the cold air out to achieve the cooling effect of the air cooler. When the cold water in the lower water tank is at a low level, the upper water tank continues to supply water to the lower water tank.
[0020] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
