Technical Field

[0001] The utility model relates to the technical field of filtering devices for heating, ventilation and air conditioning (HVAC), and particularly relates to a filtering device for HVAC. Background Art

[0002] HVAC is an air conditioner with heating, ventilation and air conditioning functions. Since the main functions of HVAC include: heating, ventilation and air conditioning in these three aspects, the structure of HVAC is relatively complex, the exhaust power is relatively high, and it is in a long-term working state. Therefore, the filtering device of HVAC needs to be cleaned regularly.

[0003] For example, the patent application number CN202023202127.1 discloses a filtering device for HVAC, including a first connecting pipe, a filtering housing, a top cover sealing ring, a top cover, an end cover, a first sealing ring, a second connecting pipe, a rotating blade, an activated carbon layer, an activated carbon storage housing, a connecting rod, an inner housing, an inlet, an ash accumulation storage box, a second sealing ring, a filter screen and a filter screen fixing frame. By sleeving the inner wall of the end cover on the end wall surface of the filtering housing and then fixing it with bolts, and by clamping the edge of the activated carbon storage housing on the inner wall of the inner housing, and arranging an activated carbon layer inside the activated carbon storage housing, the gas is adsorbed by the activated carbon layer, so as to prevent the bacteria from breeding inside the filtering housing and affecting human health. By rotatably connecting the end of the rotating blade to the inner wall of the second connecting pipe, the wind direction is changed by changing the angle of the rotating blade.

[0004] Based on the retrieval of the above patent and the combination with the equipment in the prior art, it is found that although the above equipment can solve the problems that the existing filtering device is difficult to disassemble, resulting in the filtering device not being able to be cleaned regularly according to the usage time and usage instructions, causing a large amount of dust and impurities to accumulate inside the filtering device, on the one hand, it affects the exhaust effect of HVAC, and on the other hand, it affects the health and safety of users due to the bacteria breeding inside the filtering device. However, during the use process, the filter screen is used to filter the dust in the air and the dust is collected by the ash accumulation storage box, but the filter screen is not provided with a cleaning structure, and it is difficult to clean the attached dust only through the inclination of the filter screen itself. Therefore, a large amount of dust still adheres to the filter screen after long-term use, and there are certain limitations. Content of the Utility Model

On the front and rear sides of the inner wall of the filter housing, fixed slots are opened. On the left side inside the fixed slots, transmission components are fixedly connected.

[0007] Preferably, the vibration component includes a vibration block. A vibration motor is fixedly installed on the vibration block. The right side of the vibration block is fixedly connected with the left side of the vibration frame. On the inner sides of the inner walls of the installation slots, springs are fixedly connected. The inner ends of the springs are fixedly connected with the vibration block.

[0008] Preferably, the transmission component includes a motor. The output end of the motor is fixedly connected with a screw rod. The surface of the screw rod is threadedly connected with a nut sleeve. The inner side of the nut sleeve is fixedly connected with the moving plate.

[0009] Preferably, on the outer sides of the inner walls of the installation slots, limit telescopic rods are fixedly connected. The inner ends of the limit telescopic rods are fixedly connected with the vibration block.

[0014] 1. By setting the vibration frame, the vibration frame can drive the cleaning brush to vibrate and clean the dismountable filter plate. When in use, the filter screen filters the dust in the air and the dust is collected by the dust collection box. However, the filter screen is not provided with a cleaning structure, and it is difficult to clean the attached dust only through the inclination of the filter screen itself, resulting in a large amount of dust still adhering to the filter screen after long-term use, which has certain limitations. The present utility model has the advantage of auxiliary cleaning.

[0015] 2. By setting the vibration assembly, after the vibration motor fixedly installed inside the vibration block is started, it can drive the vibration block to vibrate inside the installation groove.

By setting the transmission assembly, after the motor is started, it can drive the screw rod to rotate. After the screw rod rotates, it can drive the movement inside the fixed groove, so that the screw sleeve can drive the moving plate to move, and thus the moving plate can drive the vibration frame to move.

[0016] 3. By setting the limit telescopic rod, the use of the limit telescopic rod can limit the vibration block inside the installation groove, thus preventing the vibration block from separating from the installation groove during use. By setting the movable roller, the movable roller can reduce the friction between the vibration block and the inner wall of the installation groove, so that the vibration block will not get stuck when vibrating up and down inside the installation groove.
