[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this application, the gas delivered to the air outlet housing is first purified by a filter to ensure that the gas delivered into the room meets the cleanliness standards. The purified gas is then discharged from the bottom grille and then delivered to the room as clean air. During this process, the impurities generated are captured by a specific collection box. In addition, the user can easily disassemble and clean the collection box containing the impurities by a simple pressing operation.

[0014] 2. In this application, the operation of the drive motor enables the reciprocating screw to rotate, which in turn drives the cleaning scraper to move back and forth along the filter screen, thereby achieving automatic cleaning of the filter screen. This process effectively reduces the labor intensity of workers. At the same time, during the rotation of the reciprocating screw, the striking ball at the end of the spring also rotates, and its impact acts on the striking seat on the filter screen frame, thereby causing the filter screen to vibrate. This vibration helps to remove impurities from the filter screen. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a top-suspended air supply device, including an air outlet housing 1, a bottom grille 2 at the bottom of the air outlet housing 1, a connection port 4 at the top of the air outlet housing 1, an air inlet pipe 3 connected inside the connection port 4, a filter mechanism 5 inside the air outlet housing 1, and a cleaning mechanism 6 above the filter screen frame 501. The filter mechanism 5 can filter the air supplied into the room, and the cleaning mechanism 6 can facilitate the user to clean the filter screen 502.

[0022] like Figure 2 and Figure 3 As shown, the filter mechanism 5 includes a filter frame 501 fixedly installed inside the air outlet housing 1, a filter 502 fixedly installed on the filter frame 501, and installation notches 503 on both sides of the filter frame 501. A collection box 504 is connected inside the installation notch 503. Buckles 506 are fixedly installed at both ends of the collection box 504. A sealing ring 507 is fixedly installed at the upper end of the collection box 504. An installation groove 505 is provided on the filter frame 501, and the filter 502 is installed on the filter frame 501 through the installation groove 505.

[0023] Specifically, the gas delivered into the air outlet housing 1 passes through the filter screen 502, thereby filtering the gas delivered into the room. The filtered gas is discharged from the bottom grille 2, thus delivering clean gas into the room. The impurities generated during cleaning are collected by the collection box 504. At the same time, the user can simply press the buckle 506 to remove the collection box 504 containing impurities for cleaning.

[0024] like Figure 2 and Figure 4 As shown, the cleaning mechanism 6 includes a positioning guide rod 604 fixedly installed above the filter frame 501 and a reciprocating screw 607 movably installed above the filter frame 501. The reciprocating screw 607 is provided with a screw nut 605, and a cleaning scraper 606 is fixedly installed on the screw nut 605. A drive motor 608 is fixedly installed on the air outlet housing 1. A striking seat 602 is fixedly installed on the filter frame 501. A spring 603 is fixedly installed at the end of the reciprocating screw 607, and a striking ball 601 is fixedly installed at the end of the spring 603. The striking ball 601 is movably installed above the striking seat 602 through the spring 603.

[0025] Specifically, the drive motor 608 can drive the reciprocating screw 607 to rotate. After the reciprocating screw 607 rotates, it will drive the cleaning scraper 606 to move back and forth against the filter screen 502, thereby automatically cleaning the filter screen 502 and reducing the labor intensity of workers. During the rotation of the reciprocating screw 607, it will also drive the striking ball 601 at the end of the spring 603 to rotate. The rotating striking ball 601 will hit the striking seat 602 on the filter screen frame 501, causing the filter screen 502 to vibrate, which will facilitate the removal of impurities from the filter screen 502.

[0026] Working Principle: During use, the entire device is installed on the ceiling. When installed on the ceiling, the air inlet pipe 3 delivers gas to the outlet housing 1. Inside the outlet housing 1, the gas is purified by the filter screen 502, thus filtering the incoming indoor air. The purified gas is then discharged through the bottom grille 2, ensuring clean air is delivered to the indoor environment. During use, the user can start the drive motor 608. Starting the drive motor 608 will rotate the reciprocating screw 607, which in turn will drive the screw nut 605 to reciprocate back and forth. This reciprocating motion of the screw nut 605 will cause the cleaning scraper 606 to adhere to the filter screen 502. The reciprocating motion of the screw 607 automatically cleans the filter screen 502, reducing the labor intensity of workers. During the rotation of the reciprocating screw 607, the striking ball 601 at the end of the spring 603 will rotate. The rotating striking ball 601 will hit the striking seat 602 on the filter screen frame 501, causing the filter screen 502 to vibrate and facilitate the removal of impurities from the filter screen 502. During the cleaning process, the air supply is stopped and the fan inside the air outlet housing 1 is controlled to rotate in the opposite direction, so that the air outlet housing 1 is filled with air, preventing dust from falling into the room during the cleaning process. At the same time, the reciprocating motion of the cleaning scraper 606 will push the impurities into the collection box 504 for storage. The user can simply press the buckle 506 to remove the collection box 504 containing impurities for cleaning.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
