Description

Technical Field

[0001] This utility model relates to the field of water-cooled fans, and in particular to a household water-cooled fan. Background Technology

[0002] Current water-cooled fans utilize a pump placed inside a water tank to draw water onto a surface that sprays it onto the honeycomb filter layer. However, this method requires the pump to be submerged in water for extended periods, necessitating a waterproof design, which increases the pump's cost. Furthermore, prolonged immersion in water can lead to pump leakage, failure, and even electrical leakage, posing a safety hazard to users. Additionally, the pump's motor heats up during continuous operation, causing the water temperature to rise and impacting the cooling performance of the water-cooled fan.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems. We provide a household water-cooled fan that solves the problems of water pump leakage and water leakage by improving the installation position of the water pump.

[0018] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0019] Please refer to Figure 1-3This application provides a household water-cooled fan, which includes a housing. Inside the housing are a fan casing 1, a water tank 2, a pump body 3, a water curtain 4, and a water channel 5. The fan casing 1 contains an exhaust device, specifically composed of a motor and fan blades. The air outlet of the fan casing 1 corresponds to the air outlet grille 6 on the front side of the housing. The water curtain 4 is positioned between the air inlet of the fan casing 1 and the air inlet grille 7 on the rear side of the housing. The water channel 5 is located on top of the water curtain 4 and is used to guide water onto the water curtain 4. When the exhaust device is working, outside air passes through the water curtain and enters the fan casing. The air passing through the water curtain is filled with moisture, so after being output from the air outlet grille, the moisture-filled air can quickly lower the ambient temperature and bring a feeling of humidity. The bottom of the water curtain 4 has a water receiving trough 8, which has a drain outlet 9 connected to the water tank 2. Excess water on the water curtain collects in the water receiving trough and flows back into the water tank through the drain outlet. The bottom of the water curtain 4 is inserted into the water receiving trough 8, and the drain outlet 9 is connected to the water tank 2 through the drain pipe. The pump body 3 is installed on the outer casing and away from the water tank 2 and the water curtain 4. The water inlet end of the pump body 3 is connected to the water tank 2 through the water inlet pipe 10, and the water outlet end of the pump body 3 is connected to the water guiding trough 5 through the water outlet pipe 11. The pump body adopts a diaphragm vacuum pump. The reciprocating motion of the diaphragm changes the pump chamber volume, forming a pressure difference to pump water onto the water guiding trough. Since the pump body is set away from the water source, its waterproof level requirement is reduced. Compared with submersible pumps, the manufacturing cost is lower, which helps to reduce the development cost of water-cooled fans and promote product sales. At the same time, it can avoid leakage problems caused by water seepage and reduce the failure rate of water-cooled fans.

[0020] The water tank 2 is equipped with a water filter 12. The water inlet pipe 10 is connected to the water outlet of the water filter 12. The water filter includes a filter box and water filtration materials, such as activated carbon, calcium sulfite and other filter materials, which can effectively filter out impurities such as microorganisms, bacteria, silt, residual chlorine, heavy metals, scale, and chemical residues.

[0021] The front side of the outer shell is provided with an air guide wall 13, which is connected to the air outlet of the air shell 1. The air guide wall can prevent air leakage when the air shell is venting, and ensure the output air force.

[0022] The rear side of the housing is provided with an opening, and a detachable cover plate 14 is provided on the opening. The air inlet grille 7 is provided on the cover plate 14. The water curtain 4 can be removed from the opening so that the user can remove the water curtain for replacement or cleaning.

[0023] The water guide trough 5 is evenly provided with multiple water outlets, which correspond to the top of the water guide curtain 4, to ensure that the water guide trough can evenly deliver water to the water guide curtain.

[0024] To facilitate user movement of the water-cooled fan, the bottom of the casing is equipped with sliding wheels 15.

[0025] The front of the outer shell is provided with a strip window 16 to show the water level of the water tank 2, and the side of the outer shell is provided with a water inlet. The water inlet is provided with a normally closed flip cover 17. Users can check the water level of the water tank through the strip window. When the water level is found to be insufficient, the flip cover can be opened to add water.

[0026] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
