Description

Technical Field

[0001] This invention relates to a water-cooled fan. Background Technology

[0002] Water-cooled fans, also known as evaporative air coolers or evaporative air coolers, are devices that use the principle of water evaporation to absorb heat and cool the air. Their core working mechanism is as follows: a water pump delivers water to a honeycomb-shaped evaporative cooling pad. When the fan draws in hot air and passes through the humidified pad, the water evaporates, absorbing heat and thus blowing out a cool, humid airflow that is about 3 to 5 degrees Celsius lower than the room temperature. Their significant advantages include energy saving, with power consumption typically between 60 and 80 watts, affordable prices, and the humidifying effect that makes dry environments more comfortable, making it an environmentally friendly and economical cooling option.

[0057] A receiving cavity 106 is provided between the air guide lip 102 and the front grille 101 of the machine head, and the front water outlet pipe of the water pipe assembly is located in the annular receiving cavity.

[0058] The air guide lip 102 includes a mounting ring 1021 and an air guide ring 1022. The plane of the mounting ring is perpendicular to the axis of the rear grille of the machine head, and one end of the air guide ring is integrally formed with the mounting ring.

[0068] Using a screwdriver and other tools, the front grille of the machine head is installed with the mounting post with screw holes by reaching into the rear grille of the machine head.

[0069] The water pipe assembly 103 includes a rear water inlet pipe 1031, which is connected to the rear ends of two front water outlet pipes 1033 via a quick-connect tee. The front ends of the front water outlet pipes are respectively connected to water outlets.

[0070] The front water outlet pipe is connected to the water outlet via a quick-connect tee in the middle.

[0071] The rear grille of the machine head is provided with a rear water inlet pipe mounting groove on the top inner side. The mounting ring is provided with a mounting through hole. The rear water inlet pipe enters the receiving cavity through the mounting through hole and is connected to the quick-connect tee.

[0072] The rear water inlet pipe is installed into the rear water inlet pipe mounting groove after passing through the base and support column in sequence.

[0073] A guide ring was added at the air outlet of the blades to direct the airflow smoothly in one direction, greatly reducing the turbulence and vortex phenomenon at the blade tip, making the fan quieter and with a larger air volume at the same speed (Bernoulli effect).

[0074] Meanwhile, the cavity formed by the air guide ring facilitates water circuit installation and wiring, solves the complex piping problem of water-cooled fans, eliminates sealing components such as clamps and rubber rings, simplifies the structure for easier production, facilitates increasing the number of nozzles, and makes the water circuit system less exposed and more rationally arranged.

[0075] The head support structure 200 includes a support body and a rotating shaft 202.

[0076] The supporting body includes two support columns 201. The tops of the two support columns are connected to the rear grille 104 of the engine head via a rotating shaft. The rear grille of the engine head adjusts the pitch angle of the engine head via the rotating shaft 202.

[0077] At least one of the two rotating shafts is a hollow rotating shaft. The rear water inlet pipe 1031 of the water pipe assembly is connected to the front water outlet of the front grille of the water-cooled fan head via the base 107, the support column 201 for installing the hollow rotating shaft, the hollow rotating shaft 202, and the rear grille of the machine head.

[0078] The head support structure includes a motor mounting base 203, the front side of which is fixed to the fan motor.

[0079] The rear side of the motor mounting base 203 is fixed to the rear grille of the machine head. Both the motor mounting base and the rear grille of the machine head are provided with matching semi-circular bearing surfaces 2032. The rear grille of the machine head is installed with the front part of the rotating shaft through the mounting holes formed by the semi-circular bearing surfaces. The rear part of the rotating shaft is fixed to the support column.

[0080] The semi-circular bearing surface of the motor mounting base and the semi-circular bearing surface of the rear grille are assembled into a circular shaft, which realizes the axial and radial limit of the rotating shaft, but also satisfies the function of rotating around the shaft.

[0081] In this embodiment, "front end" and "front side" refer to the forward position in the wind direction, while "rear end" and "rear side" refer to the rear position in the wind direction.

[0082] The motor mounting base is provided with two elastic positioning pins 2031, which are located outside the mounting hole. The middle part of the rotating shaft is provided with an axial limiting groove 2023 that matches the elastic positioning pins.

[0083] The elastic positioning pin is installed on the motor mounting base and works with the axial limiting groove. The elastic positioning pin and the axial limiting groove on the rotating shaft form a limit, so that the head assembly can have different angles of elevation.

[0084] The rear of the rotating shaft 202 is provided with an elastic buckle 2021 fixed to the support column and a waist-shaped limiting member 2022. The support column is provided with a waist-shaped hole that matches the shape of the waist-shaped limiting member. The waist-shaped limiting member and the waist-shaped hole prevent the rotating shaft from rotating relative to the support column.

[0085] The rear of the rotating shaft has an elastic buckle, and the rear part has an oblong hole design. It is fixed to the support column in the axial direction by the elastic buckle, and in the radial direction by the two straight surfaces of the oblong hole. This realizes the integration of the rotating shaft and the support column (limiting and fixing), ensuring that the rotating shaft itself will not rotate.

[0086] The front of the pivot points towards the center, and the rear points away from the center.

[0087] The outer side of the rear grille of the machine head is provided with two strip grooves 205, the shape of which matches the support column, and the motor mounting base is located between the two strip grooves.

[0088] Both shafts 202 are hollow shafts. The wires of the water-cooled fan are connected to the rear grille of the machine head from the base through the support column and the hollow shaft. The top inner side of the rear grille of the machine head is provided with two mounting slots 204, and the entrance direction of each mounting slot 204 is aligned with a hollow shaft.

[0089] The two mounting slots are used to install the rear water inlet pipe and the wire, respectively.

[0090] The water-cooled fan head is divided into left and right halves. The mounting slot on the left side is opposite to the hollow shaft on the right side, and the mounting slot on the right side is opposite to the hollow shaft on the left side. This arrangement reduces the bending of water pipes and wires, increasing their service life.

[0091] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
