Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a self-cleaning air supply outlet. Background Art

[0002] An air supply outlet refers to the pipe orifice that transports air from the center of an air-conditioning duct to the room. Usually, the outer shell of the air supply outlet is made of high-quality cold-rolled steel plate, with electrostatic spraying on the surface, and includes a static pressure box, a high-efficiency filter, and a diffuser plate. It can be used as a terminal high-efficiency filtration device on a clean ceiling, etc., and has the advantages of low investment and simple construction. Currently, some air supply outlets usually have ventilation through-holes at the bottom.

[0003] Publication No. CN212806008U discloses a high-efficiency air supply outlet with an automatic cleaning function, including an air supply pipe. A connecting plate is fixedly connected to the orifice of the air supply pipe. A filter net is fixedly connected inside the connecting plate. A limiting rod is fixedly connected to the inner wall of the air supply pipe. A reciprocating lead screw is rotatably connected to the inner wall of the air supply pipe. A cleaning mechanism is arranged between the limiting rod and the reciprocating lead screw. An installation plate is fixedly connected to the inner bottom of the air supply pipe. A power mechanism is arranged on the installation plate. An installation cavity is arranged inside the side wall of the air supply pipe. A transmission mechanism is arranged inside the installation cavity. The structure of this utility model is reasonably designed. When the purifier supplies air, the wind force drives the fan to rotate, and then drives the brush plate to move up and down reciprocally. In this way, the side wall of the filter net can be cleaned, avoiding the deterioration of the purification effect caused by dust accumulation on the filter net. However, the prior art still has drawbacks:

[0004] Through the combined action of the power mechanism, the transmission mechanism and the cleaning mechanism of the prior art air supply outlet, when the purifier supplies air, the wind force drives the fan to rotate, and then drives the brush plate to move up and down reciprocally. Although it can avoid the deterioration of the purification effect caused by dust accumulation on the filter net, the dust swept down cannot be effectively collected and processed, and the swept-down dust will scatter inside the air supply pipe, resulting in serious pollution inside the air supply pipe.

[0011] Diversion component, the diversion component is arranged at the lower end of the air delivery pipe, including a diversion pipe, ventilation holes, a baffle and an electric telescopic rod. The diversion pipe is fixedly connected to the middle part of the lower end of the air delivery pipe. The ventilation holes are opened at the middle part of the lower end of the air delivery pipe. The baffle is rotatably connected to the inside of the baffle. One end of the electric telescopic rod is hinged to the middle part of the lower end of the baffle, and the other end of the electric telescopic rod is hinged to the middle part of the front end inside the diversion pipe.

[0012] As an improvement, a hair dryer is fixedly connected to the rear part inside the air inlet pipe.

[0013] As an improvement, stop blocks are fixedly connected to the upper ends on both sides inside the air delivery pipe.

[0014] As an improvement, a support block is fixedly connected to the front end of the upper side inside the diversion pipe.

[0015] The advantages of the present utility model compared with the prior art are as follows: The present utility model cleans the filter screen by installing a cleaning component and a diversion component. When cleaning the dust attached to the filter screen, first start the electric telescopic rod to control the baffle to rotate until the baffle is limited by the stop block, then block the rear part of the air delivery pipe to prevent pollution of the rear part of the air delivery pipe. After starting the hair dryer to blow air, start the motor. The motor drives the two cleaning brushes attached to the surface of the filter screen to rotate. The dust attached to the filter screen falls off and is sucked by the hair dryer and then enters the inside of the diversion pipe, and then is transported to the collection location by the diversion pipe. This not only effectively cleans the filter screen, maintains the operation efficiency of the equipment, but also protects the cleanliness of the environment around the equipment and prevents secondary pollution to the rear part of the air delivery pipe during the cleaning process.
