Description

Technical Field

[0001] The utility model relates to the technical field of air intake devices, in particular to an air intake device which is easy to clean. Background Art

[0002] The air intake device is a specific device that is mainly used to draw external air into the room or inside the equipment. Its product structure is mainly composed of the outer shell, fan blades, motor, control circuit and other parts. When the fan blades rotate driven by the motor, a negative pressure area is generated, thereby drawing in the outside air. At the same time, the rotation of the fan blades will do work on the air, increasing the pressure and speed of the air. Finally, this high-speed and high-pressure air will be transported to the equipment or places where air is needed. The product advantages of the air intake device mainly include simple structure, easy maintenance, low noise, large air volume, high reliability and long service life. This makes the air intake device widely used in various industrial equipment, air conditioning systems, ventilation systems, purification equipment and other scenarios.

[0003] Among them, when the air intake device is in use, an air intake grille will be installed on the air intake part of the air intake device, so that the air intake of the air intake device can be filtered through the air intake grille to prevent larger foreign matter or impurities from entering the interior of the air intake device through the air intake.

[0004] However, when the prior art is actually used, during the process of using the air intake grille to filter the air intake of the air intake device, foreign matter or impurities will be blocked by the air intake grille, resulting in the accumulation of foreign matter or impurities at the front end of the air intake grille after long-term use, which can easily cause blockage of the air intake device. At the same time, when the air intake part of the air intake device is installed at a higher position, it will be inconvenient to clean the air intake grille. Utility Model Content

[0005] The purpose of the utility model is to provide an air intake device that is easy to clean, so as to solve the problem proposed in the above background technology that in the process of using the air intake grille to filter the air inlet of the air intake device, foreign matter or impurities will be blocked by the air intake grille, resulting in foreign matter or impurities being accumulated at the front end of the air intake grille after long-term use, thereby easily causing blockage of the air intake device; at the same time, when the air inlet part of the air intake device is installed at a higher position, it will cause inconvenience in cleaning the air intake grille.

[0006] To achieve the above object, the utility model provides the following technical solution: comprising an air intake device body, wherein an air intake grille for blocking and filtering the air inlet at the front end of the air intake device body is fixedly installed at the front end of the air intake device body;

[0007] The top of described sliding panel also is provided with an upper sliding block, and the lower sliding block is threadedly connected with the outer curved surface of two sliding blocks at two ends of the driving motor.

[0008] Preferably, the top ends of both sides of the transmission screw are rotatably connected to the inner walls of the upper limit straight slide groove plate via a rotating shaft, and the threads of the outer curved surfaces at both ends of the transmission screw itself face in opposite directions.

[0009] Preferably, there are two upper sliders, which are symmetrically distributed on the outer curved surfaces of the two side ends of the transmission screw rod. The outer ends of the two side ends of the upper slider are movably connected to the inner wall of the upper limit straight slide groove plate, so that the upper slider can be limited in linear sliding by the upper limit straight slide groove plate.

[0010] Preferably, the lower slider and the upper slider are on the same vertical line, and the outer ends on both sides of the lower slider are movably connected to the inner wall of the lower limit straight slide groove plate, so that the lower slider can be limited in linear sliding by the lower limit straight slide groove plate and the limit slide rod.

[0011] Preferably, the lower top of the transmission shaft column is rotatably connected to the upper top of the lower sliding block via a rotating shaft, and the bottom of the transmission rack is fixedly installed on the front side of the lower limit straight slide plate.

[0012] Preferably, there are two mounting brackets, which are symmetrically distributed on both sides of the front end of the upper limit straight slide plate, and the upper opening of the cleaning nozzle is connected to the external water pipe through a connecting hose.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] When the upper slider moves linearly inwardly synchronously, the cooperation of the lower slider will drive the transmission shaft column to move linearly inwardly synchronously. When the transmission shaft column moves linearly inwardly synchronously, the cleaning soft brush roller will be driven to move linearly inwardly synchronously. At the same time, when the transmission shaft column moves linearly inwardly synchronously, the transmission gear will be driven to move linearly inwardly synchronously. When the transmission gear moves linearly inwardly synchronously, the force generated by the meshing connection between the transmission gear and the transmission rack will drive the transmission gear to rotate. When the transmission gear rotates, the transmission shaft column will be driven to rotate. When the transmission shaft column rotates, the cleaning soft brush roller will be driven to rotate, so that the cleaning soft brush roller can rotate while moving linearly inwardly synchronously. Therefore, the air intake grille can be cleaned by the cleaning soft brush roller that moves linearly inwardly synchronously and rotates, thereby facilitating the cleaning of the air intake grille and avoiding the blockage of the air intake port of the air intake device body.

[0015] The utility model also can realize that when the upper opening of the cleaning nozzle is connected with the external water pipe through the connecting hose, the cleaning water can be sprayed to the cleaning soft brush roller through the cleaning nozzle by opening the external water pipe, thereby cleaning the air intake grille and facilitating the cleaning of the cleaning soft brush roller at the same time.
