Description

TECHNICAL FIELD

[0001] The utility model relates to cold -air machine technical field more specifically, the utility model relates to an evaporative cold -air machine. BACKGROUND

[0002] Evaporative cold -air machine utilizes the principle that water absorbs a large amount of heat when evaporating. When water changes from liquid to gas (evaporates), it needs to absorb heat from the surrounding environment, which will lower the temperature of the air.

[0003] The cold -air machine has a water tank inside, and the water in the water tank is transported to the humidification filler by pumping. The outside air enters through the air inlet of the cold -air machine, and the air flow passes through the humidification filler and comes into contact with the water. Because the humidification filler has a large surface area, the heat in the air is transferred to the moisture, which evaporates and absorbs heat, thereby reducing the temperature of the air. The humidified air with reduced temperature is blown out by the fan, and this cool air helps to reduce the temperature.

[0004] However, the water pump inside the existing evaporative cold -air machine is continuously working, and the water pump produces noise when working. Even if the intensity is low, the long exposure time can cause chronic health problems such as hearing loss, increased psychological stress, and decreased sleep quality, which can easily accumulate and gradually show harm.

[0025] In the embodiment of the application, the inner side of the water receiving frame 104 is filled with water. When the water pump 105 adds water to the humidification filler 106, the first electromagnetic valve 505 is closed. When the water evaporates on the surface of the humidification filler 106, the water will absorb the heat of the surrounding air, thereby reducing the temperature of the air. The air flow is driven by the fan, and the air with reduced temperature is discharged at the air direction adjusting mechanism 103.

[0026] When water is added to the humidifying filler 106 through the water storage assembly 2, the second electromagnetic valve 506 is closed and the first electromagnetic valve 505 is opened, so that the water inside the water receiving frame 104 enters the inside of the water storage tank 201 through the inlet 202. As the water level in the water storage tank 201 rises, the buoyancy ball 604 is moved upward along the inside of the fixed pipe 603 under the action of buoyancy. When the water level in the water storage tank 201 reaches a specified position, the pressing rod 605 exerts pressure on the first pressure switch 601, and the first pressure switch 601 transmits a signal to the water pump 105 and the first electromagnetic valve 505.

When the water level in the inside of the water storage tank 201 decreases to a specified position, the pressing rod 605 exerts pressure on the second pressure switch 602, and the pressing rod 605 transmits a signal to the water pump 105 and the first electromagnetic valve 505. The water pump 105 starts to work, and the first electromagnetic valve 505 is opened, thereby realizing automatic intermittent water injection work of the water pump 105, avoiding noise caused by continuous work of the water pump 105 to affect people's body and mind and hearing.

When the handle block 304 is rotated counterclockwise, the conical block 305 moves vertically upward, so that the area of the air hole 204 through which air can pass is increased. The size of the area of the air hole 204 through which air can pass can be adjusted to adjust the water outlet speed of the first water dripping pipe 203.

[0028] The device shell 1 is provided with four universal wheels 101 at the bottom of the four corners, a handle rod 102 is fixedly connected to the top of the right side of the device shell 1, and the handle rod 102 is convenient for moving the device through the universal wheels 101.

A fan is arranged on the left side of the inner wall of the device shell 1, and a flow guide plate is arranged at the bottom of the humidifying filler 106, so that water can flow back to the inside of the water receiving frame 104.

[0031] The water level monitoring assembly 6 comprises a first pressure switch 601, a second pressure switch 602 and a fixed pipe 603, the inner side of the fixed pipe 603 is provided with a buoyancy ball 604, the top and bottom of the buoyancy ball 604 are fixedly connected with pressing rods 605, the first pressure switch 601 and the second pressure switch 602 are electrically connected with the water pump 105 through wires, the ice block placing frame 4 is installed in the middle of the inner side of the device shell 1, the first pressure switch 601 is fixedly connected with the top of the inner wall of the water storage tank 201, and the second pressure switch 602 is fixedly connected with the bottom of the inner wall of the water storage tank 201.

[0032] When the pressing rod 605 extrudes the first pressure switch 601, the water pump 105 stops working, and the first electromagnetic valve 505 is closed; when the pressing rod 605 extrudes the first pressure switch 601, the water pump 105 starts working, and the first electromagnetic valve 505 is closed; the inside of the ice block placing frame 4 can hold ice blocks, so that the cold air effect is increased.
