Description

Technical Field

[0001] This utility model relates to the field of air vent grille technology, and more specifically to an air conditioning dustproof and leak-proof air outlet grille. Background Technology

[0002] The air outlet grille structure mainly includes a housing, a mounting bracket, and multiple grilles arranged in a row. The grilles are linked together by connecting rods. The mounting brackets are located on both sides of the grilles and fixed to both sides of the housing's inner cavity. The front end of the grille extends with a sealing section. When the air outlet is closed, adjacent grilles are sealed tightly together through the sealing section. The ends of the first and last grilles, as well as the sides of the grilles, are also sealed tightly to the inner wall of the housing, effectively preventing debris from entering the air conditioner and ensuring its safety.

[0003] Existing technology has shortcomings: When the air conditioner is not running, adjacent grilles are tightly sealed together. However, as the contact points wear down with use, gaps can easily appear, affecting the sealing performance of the grilles. At the same time, to prevent dust from entering the grille, a filter is installed inside the frame. As the air conditioner is used, dust can adhere to the filter and cause blockage, affecting the operation of the equipment. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an air conditioner dustproof and leakproof air outlet grille to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air conditioner dustproof and leak-proof air outlet grille, comprising a frame structure, and further comprising: a grille mechanism and a cleaning mechanism, wherein the top inner wall of the frame structure is movably connected to the top of the grille mechanism, and the side of the cleaning mechanism is movably sleeved with the side inner wall of the frame structure, the grille mechanism comprising a grille plate, the top of the grille plate being fixedly connected to an installation shaft, the top of the installation shaft being movably sleeved with the top inner wall of the frame structure, a filter screen being fixedly connected to the side inner wall of the frame structure, an installation groove being provided on the side of the grille plate, a pressure spring being fixedly connected to the side of the installation groove, and a sealing strip being fixedly connected to the side of the pressure spring.

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The air conditioning dustproof and leak-proof air outlet grille involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Reference Figures 1 to 8This utility model provides a dustproof and leak-proof air outlet grille for an air conditioner, including a frame structure 1, and further including a grille mechanism 2 and a cleaning mechanism 3. The top inner wall of the frame structure 1 is movably connected to the top of the grille mechanism 2, and the side of the cleaning mechanism 3 is movably sleeved with the side inner wall of the frame structure 1. The grille mechanism 2 includes a grille plate 201, the top of which is fixedly connected to an installation shaft 205, the top of which is movably sleeved with the top inner wall of the frame structure 1. A filter screen 103 is fixedly connected to the side inner wall of the frame structure 1. The side of the device has an installation groove 210. A pressure spring 208 is fixedly connected to the side of the installation groove 210. A sealing strip 203 is fixedly connected to the side of the pressure spring 208. When the device is not in use, the installation shaft 205 rotates, causing the grid plate 201 to rotate so that the adjacent grid plates 201 are kept in the same straight line. The sealing strips 203 on both sides of the grid plate 201 contact the sealing strips 203 on the sides of the adjacent grid plate 201. At this time, the pressure spring 208 pushes the sealing strips 203 so that the sealing strips 203 on both sides are tightly pressed together, avoiding gaps between adjacent grid plates 201.

[0026] The sealing strip 203 has a groove 209 on its side. The groove 209 has an L-shaped structure and a rounded corner on its side. When adjacent sealing strips 203 are attached together, the sides of the grooves 209 engage with each other, so that the joints are staggered and the seal is prevented from being opened.

[0027] Among them, a groove 104 is provided on the inner side wall of the frame structure 1 corresponding to the position of the sealing strip 203, and a stop block 101 is fixedly connected to the inner side wall of the frame structure 1 corresponding to the position of the sealing strip 203. When the grid plate 201 near the inner wall of the frame structure 1 comes into contact with the frame structure 1, the slot 209 is inserted into the groove 104 and the stop block 101 to avoid gaps at the joint.

[0028] The frame structure 1 has an internal cavity. A servo motor 206 is fixedly connected to the side of the cavity. A transmission rod 202 is fixedly connected to the output shaft of the servo motor 206. A worm gear 207 is fixedly sleeved on the side of the transmission rod 202. A worm wheel 204 is fixedly sleeved on the side of the mounting shaft 205. The side of the worm wheel 204 meshes with the side of the worm gear 207. The servo motor 206 drives the transmission rod 202 to rotate. The meshing of the worm gear 207 and the worm wheel 204 drives the mounting shaft 205 to rotate, thereby driving the grid plate 201 to rotate.

[0029] The cleaning mechanism 3 includes a drive shaft 302, the side of which is movably sleeved with the inner side wall of the frame structure 1. A mounting plate 301 is movably sleeved with the side of the drive shaft 302. A slide groove 102 is provided at the top of the frame structure 1. The side of the mounting plate 301 is movably connected with the side of the slide groove 102. A scraper 308 is fixedly connected to the side of the mounting plate 301. The side of the scraper 308 is movably connected to the side of the filter screen 103. A drive motor 306 is fixedly connected to the inner wall of the frame structure 1. The output shaft of the drive motor 306 is fixedly connected to the side of the drive shaft 302. The drive motor 306 drives the drive shaft 302 to rotate, thereby driving the mounting plate 301 to reciprocate along the slide groove 102, so that the scraper 308 cleans the surface of the filter screen 103, preventing debris from adhering to the filter screen 103 and causing blockage.

[0030] The mounting plate 301 has a slider 307 movably connected to its side via a pin. The drive shaft 302 has a bidirectional helical groove 305 on its side. The side of the bidirectional helical groove 305 is movably connected to the side of the slider 307. When the drive shaft 302 rotates, the slider 307 slides along the bidirectional helical groove 305. When the slider 307 moves to both ends of the bidirectional helical groove 305, the ring structure at both ends of the bidirectional helical groove 305 enables the mounting plate 301 to rotate, thereby realizing the reciprocating operation of the mounting plate 301.

[0031] The mounting plate 301 is fixedly connected to the side of an air guide pipe 303, and the side of the air guide pipe 303 is fixedly connected to an air outlet pipe 304. The side of the mounting plate 301 is fixedly connected to an air pump via an air pipe. During the movement of the mounting plate 301, the high-pressure air pump operates and blows high-speed airflow through the air guide pipe 303 and the air outlet pipe 304 to blow air onto the filter screen 103, so as to prevent the mesh holes of the filter screen 103 from being blocked.

[0032] The working principle of this utility model is as follows: The frame structure 1 is installed on the air conditioner outlet. When the air conditioner is running, the servo motor 206 is started to drive the transmission rod 202 to rotate. Through the meshing of the worm gear 207 and the worm wheel 204, the mounting shaft 205 is driven to rotate, thereby driving the grid plate 201 to rotate, so that the grid plate 201 is perpendicular to the frame structure 1. Air flows through the gaps between the grid plates 201 to the inside and outside of the frame structure 1. When it is necessary to clean the filter screen 103, the drive motor 306 is started to drive the transmission shaft 302 to rotate. The slider 307 slides along the bidirectional helical groove 305. When the slider 307 moves to both ends of the bidirectional helical groove 305, due to the annular structure at both ends of the bidirectional helical groove 305, the filter screen 103 rotates. The mounting plate 301 is now rotated, allowing it to reciprocate along the slide groove 102. This causes the scraper 308 to clean the surface of the filter screen 103. Simultaneously, the high-pressure air pump operates, spraying high-speed airflow through the air guide pipe 303 and the air outlet pipe 304 to blow air onto the filter screen 103, preventing the mesh holes of the filter screen 103 from becoming clogged. When the equipment is not in use, the servo motor 206 is reversed to keep the adjacent grid plates 201 in a straight line. The sealing strips 203 on both sides of the grid plate 201 contact the sealing strips 203 on the sides of the adjacent grid plate 201. At this time, the pressure spring 208 pushes the sealing strips 203 to make the sealing strips 203 on both sides stick together tightly, preventing gaps between adjacent grid plates 201.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
