Technical Field

The utility model relates to the technical field of cooling fans, in particular to a floor-standing automatic water-adding atomizing fan.

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 matching equipment, the cooling effects of existing atomizing fans vary.

A "spray fan" disclosed in a Chinese patent (patent application number is 202220984877.9) includes a shell, a motor is fixedly assembled and connected inside the shell, and a plurality of fan blades are fixedly assembled and connected to the output shaft of the motor; a flow guide component is fixedly connected inside the shell; the flow guide component includes a conical flow guide cover fixedly connected to the motor shell; the conical flow guide cover is located on the right side of the fan blades, and the cover opening of the conical flow guide cover is set to the right; the flow guide component also includes a plurality of guide vane plates fixedly assembled on the left side of the conical flow guide cover; the bottom of the shell is assembled and connected to a box body; the spray fan also includes a spray mechanism corresponding to the flow guide component, and the spray mechanism includes a spray disk arranged in the shell, and the spray disk is located on the right side of the conical flow guide cover, and the spray disk is connected to a water pump.

DETAILED DESCRIPTION

The following is a further description of the present invention in conjunction with the accompanying drawings and embodiments. The following description is in the form of examples, but the protection scope of the present invention should not be limited thereto.

Embodiment 1:

The floor-standing automatic water-adding atomizing fan of the present embodiment is composed of a fan motor 18, a fan blade 2, a fan blade cover 1, an atomizing assembly 3, a frame 6, a switch assembly 5, and a water tank assembly.

The frame 6 is composed of two square tubes, and a crossbeam is added to the upper end thereof. The bracket (not shown in the accompanying drawings, see Figure 2) at the lower part of the fan motor 18 is installed on the crossbeam of the frame 6.

The fan blade 2 is installed at the output shaft end of the fan motor 18, and the fan blade cover 1 is divided into two parts, front and back, which wrap the fan blade 2.

The atomization assembly 3 is composed of an atomization bottom cover 21, an atomization motor 27, an atomization disc 23, an atomization disc cover 22, a water spray nozzle 26, a residual water reflux outlet pipe 4, a residual water collection cover 24 and an atomization bottom cover mounting bracket (not marked in the accompanying drawing, see Figure 2) and a residual water drainage nozzle 25.

The atomizing bottom cover 21 is a hollow truncated cone with a bottom, and its inner cavity is provided with a step for installing the atomizing disc cover 22; the rear side thereof is provided with an atomizing bottom cover mounting bracket (not marked in the drawings, see FIG2 ) for fixing it on the fan cover 1. The atomizing motor 27 (high-speed motor) passes through the inner cavity of the atomizing bottom cover 21 from the rear side thereof and enters a part thereof (see FIG5 ), and the atomizing disc 23 is installed at the output shaft end thereof.

The atomizing disc cover 22 is provided with a plurality of radial holes for the water mist to be discharged. The atomizing disc cover 22 is installed on the step of the inner cavity of the atomizing bottom cover 21 and covers the atomizing disc 23 .

The water spray nozzle 26 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 21 from the middle-upper part or the middle-lower part (the middle-upper part is used in this example, see Figure 5) on the rear side, and is bent (i.e., vertically folded, horizontally) to a middle position close to the atomizing disc 23, and its water spray port is perpendicular to the atomizing disc 23 at the corresponding position (its vertically folded part is fixed on the right end face of the atomizing motor 27), and its other end is connected to the water tank assembly after passing through the switch assembly 5.

The residual water collection cover 24 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 21, and a residual water drainage nozzle 25 is provided in the middle lower part. The residual water drainage nozzle 25 is connected to the water tank assembly through the residual water reflux outlet pipe 4 and the switch assembly 5.

The switch assembly 5 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 6, 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 12 (via the water pump wire 9), the fan motor 18 and the atomizer motor 27 (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 11, a water tank cover 10, a water pump 12, a water supply pipe 7, a residual water return tail pipe 8, an automatic water adding assembly and four casters 13.

A water filling hole is provided on the water tank cover 10, which is arranged at the upper end of the water tank barrel 11; the water pump 12 is arranged in the water tank barrel 11, one end of the water supply pipe 7 is connected to the output end of the water pump 12 in the water tank barrel 11, and the other end is first connected to the atomizing water volume regulating valve in the switch assembly 5, and then connected to the water spray nozzle 26; the residual water reflux outlet pipe 4 led down by the residual water drainage nozzle 25 passes through the box body of the switch assembly 5 and is connected to the upper end of the residual water reflux tail pipe 8, and the tail end of the residual water reflux tail pipe 8 is placed in the water tank barrel 11.

The automatic water adding assembly is composed of a float valve 14 and a water inlet 15 . The float valve 14 is arranged on the upper part of one side of the inner cavity of the water tank barrel 11 , and is connected to the water inlet 15 arranged on the upper part of the outer surface of the water tank barrel 11 .

A water level gauge 16 for observing the water level in the water tank 11 is also provided on one outer side of the water tank 11, and buckles 17 are respectively installed on the upper left and right sides of the water tank 11 and the corresponding parts of the water tank cover 10 to fix the water tank cover 10. Casters 13 (all of which can be universal casters with brakes, or only one universal caster with brakes and the others can be ordinary universal casters) are also provided at the four corners of the bottom of the water tank 11.

The lower upper part and the lower lower part in the lower part of the frame 6 are fixed to the upper part and the lower part of the rear side of the water tank barrel 11 by the frame upper fixing plate 19 and the frame lower fixing plate 20 respectively.

Before use, first move the water tank to a suitable position by means of casters 13, then connect the water pipe to the water inlet 15, open the water valve, and the water flows into the water tank barrel 11 through the water inlet 15 and the float valve 14. When the water level in the water tank barrel 11 reaches the control water level of the float valve 14, the float valve 14 will automatically close and the water inflow stops. When used in places with inconvenient conditions, water can also be added to the water tank barrel 11 through the water filling hole on the water tank cover 10.

When in use, the fan motor switch, the water pump switch and the atomizing motor switch are started successively, and the water in the water tank barrel 11 is pumped by the water pump 12, and is sent to the water nozzle 26 by the water supply pipe 7 through the atomizing water volume regulating valve in the switch assembly 5, and is vertically sprayed to the inner side surface (i.e., the left side surface, see Figure 5) of the atomizing disc 23 by the water spray port of the water nozzle 26; because the atomizing disc 23 rotates at a high speed, the water droplets sprayed on the inner side surface of the atomizing disc 23 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 21, broken into fine water mist, and then leaked through the multiple radial holes on the atomizing disc cover 22, so that it is entrained by the airflow generated by the fan blades 2 of the fan motor 18 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.

The water droplets that have not formed water mist in the inner cavity of the atomizing bottom cover 21 leak out through the multiple radial holes on the atomizing disc cover 22, drip downward along the inner conical slope of the atomizing bottom cover 21 into the inner groove of the residual water collecting cover 24, and flow back into the water tank barrel 11 through the residual water drainage nozzle 25, the residual water reflux outlet pipe 4, the switch assembly 5 (only passes through its box body) and the residual water reflux tail pipe 8.

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

When the water level in the water tank barrel 11 drops to the operating water level of the float valve 14, the float valve 14 will automatically open and water will start to flow in immediately.

The utility model provides a floor-standing automatic water-adding atomizing fan, which is suitable for use in factory production workshops, exhibitions and other public places.
