Abstract

The utility model relates to a cold air fan which comprises a casing, an air inlet, an air outlet and an air duct positioned between the air outlet and the air inlet, wherein a main motor and a wind wheel are arranged in the air duct, a water curtain which is driven by a synchronous motor to rotate is arranged between the air duct and the air inlet, and the lower end of the water curtain extends into a water tank at the bottom of the casing. A container, the inside of which is provided with blue ice blocks is arranged in the water of the water tank, and the blue ice blocks are formed by freezing after the blue ice absorbs the water. Because the blue ice blocks can absorb the outside heat and can continuously keep low temperature for a long time, the blue ice blocks are favorable cold keeping substances, and thus the utility model can make people enjoy cool and fresh air for a long time.

Description

Air-conditioning fan

The utility model relates to a kind of air-conditioning fan.

General air-conditioning fan is to suck hot-air by main driven by motor wind wheel from air inlet, filter by screen pack, by the cascade cooling of soaking water or frozen water, blow out cold air by air outlet again, thereby make the people feel nice and cool, as Linkage's board air-conditioning fan that produce in Shenzhen, the star brightness board air-conditioning fan that produce in Foshan etc. all belongs to this type of.The weak point of these air-conditioning fans is: because water itself is identical with environment temperature, so the wind that blows out is not nice and cool, if add ice, because the environment temperature height, ice very fast fusing, it is very short to keep the nice and cool time, the user need prepare a large amount of ice cubes and frequent the interpolation, uses very inconvenient; Common in addition screen pack can only filter general dust, can't remove the peculiar smell that some carry disease germs, and therefore can not play the effect of fresh air.

The purpose of this utility model is to provide a kind of air-conditioning fan that can send refrigerant air for a long time at the problem of above-mentioned existing air-conditioning fan existence.

The purpose of this utility model is achieved in that the utility model comprises housing, air inlet, air outlet, the air channel between air outlet and air inlet, main motor and wind wheel are installed in the air channel, the cascade that is rotated by synchronous machine drives is housed between air channel and air inlet, the lower end of cascade is stretched in the water tank of housing bottom, the container of the blue ice of dress ice cube in being placed with in the water of water tank, indigo plant ice ice cube absorbs water after the freezing ice cube that forms for blue ice.

As further improvement, the utility model is provided with screen pack on air inlet, on screen pack, be added with photocatalyst, but photocatalyst is excitation electron under the effect of ultraviolet light, these electronics can generate oxonium ion and hydroxyl ion with airborne oxygen G﹠W reaction, these ions can kill airborne bacterium and decompose peculiar smell, make people enjoy pure and fresh air, help people's health.

Technique effect of the present utility model is: blue ice, it is polyacrylic resin, be nontoxic, tasteless white powder, water insoluble, but absorptance is from the water of great several times to 1000 times, and keep no longer disengaging, be gluey after the suction, can absorb external heat after being frozen into ice cube, and can continue the long low temperature of maintenance, be the good cold insulation material,, thereby make the air that blows out very nice and cool so the utility model can make the water in the water tank keep low temperature for a long time after having placed the container of the blue ice of interior dress ice cube in the water of water tank.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is the A-A profile of Fig. 1.

Fig. 3 is the air-flow schematic diagram of the utility model embodiment.

As depicted in figs. 1 and 2, present embodiment comprises a housing 1, above the front of housing 1, be respectively equipped with air outlet 2 and air inlet 3 with the back side, on air inlet 3, be provided with screen pack 4, on screen pack 4, be added with photocatalyst, air channel 5 is between air outlet 2 and air inlet 3, be positioned at the top of housing 1, main motor 6 and wind wheel 7 are installed in air channel 5, main motor 6 is installed in the side in air channel 5, wind wheel 7 one ends are fixed on the motor shaft, the other end supports with bearing, between air channel 5 and air inlet 3 cascade 8 is housed, and cascade 8 is by driving shaft 9 and driven shaft 10 supportings, driving shaft 9 is driven by synchronous motor 11, make cascade 8 cycle rotations, the lower end of cascade 8 and driven shaft 10 stretch in the water tank 12 of housing 1 bottom, place the kettle 13 that blue ice ice cube is housed in the water of water tank 12, Lan Bing is a polyacrylic resin, and blue ice ice cube is iced suction after the freezing ice cube that forms for blue.The control circuit board of present embodiment is contained in the top of housing 1, in the bottom of housing 1 four universal wheels 14 is housed also, so that entire machine is mobile.

Using the preceding kettle 13 that blue ice will be housed to fill water is put in the refrigerator so that blue ice-cold being frozen into is indigo plant ice ice cube, again kettle 13 is put into water tank 12, water in the water tank 12 is cooled off, connect power supply then, open present embodiment, main motor 6 drives wind wheel 7 work, synchronous motor 11 drive cascades 8 also begin to rotate simultaneously, as shown in Figure 3, the air process of outside is lowered the temperature through the cascade 8 of band frozen water after being added with screen pack 4 filterings of photocatalyst and eliminating peculiar smell, enter 5 backs, air channel then and blown out by air outlet 2, so circulation makes people enjoy cool and sweet-smelling air for a long time again and again.
