Background Art

In the hot summer, some public places, such as factory workshops and exhibition booths, usually use fans to lower the temperature in order to improve the air environment. However, this cooling method can only reduce a very limited temperature. Therefore, in recent years, some atomizing fans have appeared on the market. Their working principle is to atomize water and blow it out by the fan. The blown water mist absorbs the heat of the ambient air and then evaporates to cool the ambient air. Theoretically, the cooling effect of this atomizing fan should be relatively good, but due to the large number of ways to achieve atomization, different atomization methods and other supporting equipment, the cooling effects of existing atomizing fans vary.

The fan blade 2 is installed at the output shaft end of the fan motor 4, and the fan blade cover 1 is divided into two parts, front and rear, which wrap the fan blade 2.

The atomization assembly 3 is composed of an atomization bottom cover 19, an atomization motor 25, an atomization disc 21, an atomization disc cover 20, a water spray nozzle 24, a residual water return pipe 6, a residual water collection cover 22 and an atomization bottom cover mounting bracket (not marked in the figure, see Figure 1) and a residual water drainage nozzle 23.

The atomizing bottom cover 19 is a hollow truncated cone with a bottom, and its inner cavity is provided with a step for installing the atomizing disc cover 20; the rear side thereof is provided with an atomizing bottom cover mounting bracket (not marked in the drawings, see FIG1 ) for fixing it on the fan cover 1. The atomizing motor 25 (high-speed motor) passes through the inner cavity of the atomizing bottom cover 19 from the rear side thereof and enters a part thereof (see FIG4 ), and the atomizing disc 21 is installed at the output shaft end thereof.

The atomizing disc cover 20 is provided with a plurality of radial holes for the water mist to be discharged. The atomizing disc cover 20 is installed on the step of the inner cavity of the atomizing bottom cover 19 and covers the atomizing disc 21 .

The water spray nozzle 24 is in the shape of a "B" character, which is "horizontally, vertically folded, and horizontally". It penetrates into the inner cavity of the atomizing bottom cover 19 from the middle-upper part or the middle-lower part (the middle-upper part is used in this example, see Figure 4) on the rear side, and is bent (i.e., vertically folded, horizontally) to a middle position close to the atomizing disc 21, and its water spray port is perpendicular to the atomizing disc 21 at the corresponding position (its vertically folded part is fixed on the right end face of the atomizing motor 25), and its other end is connected to the water tank assembly after passing through the switch assembly 7.

The residual water collection cover 22 is an arc-shaped groove, the rear side surface of which is fixed to the rear edge of the lower part of the atomizing bottom cover 19, and a residual water drainage nozzle 23 is provided in the middle lower part. The residual water drainage nozzle 23 is connected to the water tank assembly through the residual water reflux outlet pipe 6 and the switch assembly 7.

The switch assembly 7 is composed of a box body, a fan motor switch, a water pump switch, an atomizing motor switch and an atomizing water volume regulating valve (all not shown in the drawings).

The box body is arranged in the middle of the frame 5, and the fan motor switch, water pump switch, atomizer motor switch and atomizer water volume regulating valve are all arranged in the box body. The external power supply is connected to the water pump 18 (via the water pump wire 17), the fan motor 4 and the atomizer motor 25 (the wires of these two motors are not drawn in the accompanying drawings) through the fan motor switch, the water pump switch and the atomizer motor switch.

The water tank assembly is composed of a water tank barrel 12, a water tank cover 9, a water pump 18, a water supply pipe 8, and a residual water return tail pipe 16.

A water filling hole is provided on the water tank cover 9, which is arranged at the upper end of the water tank barrel 12; the water pump 18 is arranged in the water tank barrel 12, one end of the water supply pipe 8 is connected to the output end of the water pump 18 in the water tank barrel 12, and the other end is first connected to the atomizing water volume regulating valve in the switch assembly 7, and then connected to the water spray nozzle 24; the residual water return lead-out pipe 6 led down by the residual water drainage nozzle 23 passes through the box body of the switch assembly 7 and is connected to the upper end of the residual water return tail pipe 16, and the tail end of the residual water return tail pipe 16 is placed in the water tank barrel 12.

A water level gauge 14 for observing the water level in the tank is also provided on the front upper part of the water tank barrel 12, and buckles 13 are respectively installed on the upper parts of the left and right side surfaces of the water tank barrel 12 and the corresponding parts of the water tank cover 9 for fixing the water tank cover 9; a balancing support block 11 for supporting the water tank barrel 12 and maintaining its balance is also provided on the rear lower part of the water tank barrel 12.

Before use, first fix the frame 5 on the wall. Since the upper part of the frame 5 is bent to the right, the fan motor 4, the fan blades 2 and the fan blade cover 1 installed on the upper part are all inclined to the lower right; then, hook the water tank barrel 12 on the hook 10 at the lower part of the frame 5, and let the balance support block 11 at the lower rear of the water tank barrel 12 against the wall to maintain balance; then, add water to the water tank barrel 12 through the water filling hole on the water tank cover 9, and ensure that enough water is added by observing the water level meter 14.

When in use, the fan motor switch, water pump switch and atomizing motor switch are started successively, and the water in the water tank barrel 12 is pumped by the water pump 18, and is sent to the water nozzle 24 by the water supply pipe 8 through the atomizing water volume regulating valve in the switch assembly 7, and is vertically sprayed to the inner side surface (i.e., the left side surface, see Figure 4) of the atomizing disc 21 by the water spray port of the water nozzle 24; since the atomizing disc 21 rotates at a high speed, the water droplets sprayed on the inner side surface of the atomizing disc 21 will diffuse along the edge of the surface, and when it reaches the edge, it will be thrown to the inner wall of the inner cavity step of the atomizing bottom cover 19, broken into fine water mist, and then leaked through the multiple radial holes on the atomizing disc cover 20, so as to be entrained by the airflow generated by the fan blades 2 of the fan motor 4 and blown to the space to be cooled. When the water mist entrained by the airflow encounters the high-temperature air in the environment, the water mist will absorb the heat contained in the high-temperature air and then vaporize (i.e., evaporate), thereby reducing the ambient temperature.

By adjusting the atomizing water volume regulating valve, the amount of water sprayed can be controlled, thereby controlling the amount of atomization.

The wall-mounted atomizing fan of the utility model is suitable for use in factory production workshops, exhibitions and other public places.
