Description

Technical Field

[0001] This utility model relates to the field of windproof cap technology, specifically to an anti-clogging windproof cap. Background Technology

[0002] A ventilation cap is a ventilation device installed on the top floor of a building or at the end of a ventilation duct. It is usually shaped like a cap or has a specific streamlined structure. Its main function is to use natural wind power to guide outdoor airflow into the room or exhaust indoor air. It is widely used in steel structure buildings, residences, factories and other places. It can achieve efficient ventilation and adapt to different environmental needs through different forms.

[0003] In existing technologies, some steel-structured buildings require the installation of ventilators on the top floor. Ventilators introduce outdoor airflow into the interior, which can utilize natural wind power to achieve ventilation, improve indoor air quality, regulate indoor airflow organization, assist in heat exchange to save energy, and balance the air pressure inside and outside the building, thereby ensuring smooth indoor air circulation and improving user comfort.

[0004] However, in the face of heavy snow, snow may fall on the air inlet due to the wind. As it accumulates slowly and without self-cleaning, it may become blocked, leading to a decrease in ventilation efficiency or even completely blocking airflow and affecting the normal function of the wind cap. To address this, we propose an anti-clogging wind cap. Utility Model Content

[0005] One of the technical problems this application aims to solve is to prevent the air inlet from being blocked by heavy snow by installing a self-cleaning component in the wind cap.

[0006] To address the aforementioned technical problems, this application provides an anti-clogging vent cap, including an anti-clogging mechanism. A cleaning mechanism is provided on one side of the anti-clogging mechanism. The anti-clogging mechanism includes a rectangular plate, a side rod on one side of the rectangular plate, and one side of the rectangular plate is fixedly connected to one end of the side rod. A connector is provided at the middle end of the side rod, and the middle end of the side rod is fixedly connected to one end of the connector. A movable arm is provided on one side of the connector, and one side of the connector is rotatably connected to one end of the movable arm. A drive disk is provided at the other end of the movable arm, and the other end of the movable arm is rotatably connected to the inner side of the drive disk.

[0007] In some embodiments, the cleaning mechanism includes a scraper, a protruding rod is provided on one side of the scraper, one side of the scraper is fixedly connected to one end of the protruding rod, the other end of the protruding rod is fixedly connected to one side of a rectangular plate, an air inlet is provided on the outer side of the scraper, and the outer side of the scraper slides in contact with the inner surface of the air inlet.

[0008] In some embodiments, a rotating rod is provided at the center of the bottom side of the drive disk, the center of the bottom side of the drive disk is fixedly connected to the top end of the rotating rod, a hollow disk is provided at the bottom end of the rotating rod, and the bottom end of the rotating rod is rotatably connected to the center of the hollow disk.

[0009] In some embodiments, a spiral spring is provided on the inner side of the hollow disk, and one end of the spiral spring is fixedly connected to the inner side of the hollow disk. One end of the spiral spring at its center is fixedly connected to the outer side of the bottom end of the rotating rod.

[0010] In some embodiments, a tapered tube is provided at the top of the hollow disk, the top of the hollow disk is rotatably connected to the bottom of the tapered tube, and the top of the tapered tube is fixedly connected to the bottom side of the drive disk.

[0011] In some embodiments, a fan blade is provided on the outer side of the drive disk, and the outer side of the drive disk is fixedly connected to one end of the fan blade.

[0012] In some embodiments, the side of the hollow disc is fixedly connected to the inner side of the hood body.

[0013] In some embodiments, one side of the hood body is fixedly connected to one end of the air inlet.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. By installing fan blades on the outside of the drive plate, when the natural wind enters the wind cap body, the natural wind will exert an external force on the fan blades, and the drive plate will start to rotate. Since the movable arm is in a tilted state before the drive plate rotates, the movable arm will change angle as it rotates, and eventually become horizontal. At the same time, the rectangular plate will push out the snow that falls into the air inlet, avoiding long-term accumulation that will block the air inlet and ensuring the ventilation of the wind cap in heavy snow.

[0016] 2. The scraper is fixed to the rectangular plate by the protrusion and the scraper is in full contact with the inner wall of the air inlet. When cleaning snow, the scraper can fit against the inner wall of the air inlet. As the rectangular plate slides, the snow attached to the wall is completely scraped off, avoiding snow residue accumulation. At the same time, the full contact design can effectively eliminate cleaning dead corners and ensure that snow in every area of ​​the inner wall of the air inlet can be removed.

[0023] 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.

[0024] Example 1: Please refer to Figure 1 - Figure 4This utility model provides a technical solution: an anti-clogging vent cap, including an anti-clogging mechanism 1, a cleaning mechanism 2 on one side of the anti-clogging mechanism 1, the anti-clogging mechanism 1 including a rectangular plate 13, a side rod 14 on one side of the rectangular plate 13, one side of the rectangular plate 13 being fixedly connected to one end of the side rod 14, a connector 15 at the middle end of the side rod 14 being fixedly connected to one end of the connector 15, a movable arm 16 on one side of the connector 15 being rotatably connected to one end of the movable arm 16, a drive disk 17 at the other end of the movable arm 16 being rotatably connected to the inner side of the drive disk 17, a rotating rod 110 at the bottom center of the drive disk 17 being fixedly connected to the top end of the rotating rod 110. A hollow disk 112 is provided at the bottom end of the rotating rod 110. The bottom end of the rotating rod 110 is rotatably connected to the center of the hollow disk 112. A spiral spring 111 is provided on the inner side of the hollow disk 112. One end of the spiral spring 111 is fixedly connected to the inner side of the hollow disk 112. One end of the spiral spring 111 is fixedly connected to the outer side of the bottom end of the rotating rod 110. A tapered tube 19 is provided at the top end of the hollow disk 112. The top end of the hollow disk 112 is rotatably connected to the bottom end of the tapered tube 19. The top end of the tapered tube 19 is fixedly connected to the bottom side of the drive disk 17. A fan blade 18 is provided on the outer side of the drive disk 17. One end of the fan blade 18 is fixedly connected to the outer side of the drive disk 17. The side of the hollow disk 112 is fixedly connected to the inner side of the wind cap body 11. One side of the wind cap body 11 is fixedly connected to one end of the air inlet 12.

[0025] In use, this type of anti-clogging vent cap firstly has air inlets 12 installed on all four sides of the vent cap body 11, and these inlets are fixedly connected. The components in each air inlet 12 are identical. Furthermore, the inner wall of the air inlet 12 is rectangular, therefore, a rectangular plate 13 is designed on the inner wall of the air inlet 12. The rectangular plate 13 can slide on the inner wall of the air inlet 12. Simultaneously, a side rod 14 is designed on one side of the middle of the air inlet 12, and the two are fixedly connected. A connector 15 is installed at the middle end of the side rod 14. One side of the connector 15 is connected to a movable arm 16 via a hinge. The other end of the movable arm 16 is installed on the inner side of the drive disc 17 in the same manner. Furthermore, multiple fan blades 18 are designed along the circumferential direction on the outer side of the drive disc 17. Therefore, in heavy snow weather, the outdoor wind will enter the wind cap body 11 through the air inlet 12. During this process, the natural wind force will create an external force on the fan blades 18, and the drive disc 17 will start to rotate. Since the movable arm 16 is in a tilted state before the drive disc 17 rotates, the movable arm 16 will change its angle as it rotates, eventually becoming horizontal. At the same time, the rectangular plate 13 will push out the snow that falls into the air inlet 12, avoiding long-term accumulation that will block the air inlet, thus ensuring the smooth ventilation of the wind cap in heavy snow weather.

[0026] A rotating rod 110 is fixedly connected to the center of the bottom side of the drive disk 17. The top of the rotating rod 110 can rotate at the center of the hollow disk 112. The diameter of the hollow disk 112 is smaller than that of the drive disk 17. At the same time, a spiral spring 111 is designed on the inner side of the hollow disk 112. One end of the spiral spring 111 is connected to the rotating rod 110 at the center. When the drive disk 17 rotates and the rectangular plate 13 moves to the end of the air inlet 12, after the wind force disappears intermittently, the spiral spring 111 will store elastic potential energy due to the force it received when the drive disk 17 rotated. At this time, it will release the elastic potential energy to drive the rotating rod 110 to rotate in the opposite direction, thereby causing the drive disk 17 to rotate in the opposite direction. The movable arm 16 then returns to its original position, causing the rectangular plate 13 to slide back on the inner wall of the air inlet 12 so that when the wind force acts again, the drive disk 17 will rotate again to push the rectangular plate 13 to clear the snow, forming a reciprocating anti-clogging action.

[0027] Example 2: Please refer to Figure 1 - Figure 2 The cleaning mechanism 2 includes a scraper 21, a protruding rod 22 is provided on one side of the scraper 21, one side of the scraper 21 is fixedly connected to one end of the protruding rod 22, and the other end of the protruding rod 22 is fixedly connected to one side of the rectangular plate 13. An air inlet 12 is provided on the outer side of the scraper 21, and the outer side of the scraper 21 slides in contact with the inner surface of the air inlet 12.

[0028] A scraper 21 is designed on one side of the rectangular plate 13. The scraper 21 is fixed to the rectangular plate 13 by a protrusion and makes full contact with the inner wall of the air inlet 12. This allows the scraper 21 to fit against the inner wall of the air inlet 12 when cleaning snow. As the rectangular plate 13 slides, the snow attached to the wall is completely scraped away, preventing snow residue from accumulating. At the same time, the full contact design can effectively eliminate cleaning dead corners, ensuring that the snow in every area of ​​the inner wall of the air inlet 12 can be cleared, improving the efficiency and thoroughness of snow removal, and ensuring that the air inlet 12 is always unobstructed.

[0029] Please see Figure 1 - Figure 4By installing fan blades 18 on the outside of the drive disc 17, when the natural wind enters the wind cap body 11, the natural wind will exert an external force on the fan blades 18, causing the drive disc 17 to start rotating. Since the movable arm 16 is in a tilted state before the drive disc 17 rotates, the movable arm 16 will change angle as it rotates, eventually becoming horizontal. At the same time, the rectangular plate 13 will push out the snow that falls into the air inlet 12, preventing the air inlet from being blocked due to long-term accumulation. Furthermore, when the drive disc 17 rotates and the rectangular plate 13 moves to the end of the air inlet 12, after the wind force disappears intermittently, the spiral spring 111 will store elastic potential energy due to the force it received when the drive disc 17 rotated. At this time, it will release the elastic potential energy to drive the rotating rod 110 to rotate in the opposite direction, thereby causing the drive disc 17 to rotate in the opposite direction. The movable arm 16 will then return to its original position, causing the rectangular plate 13 to slide back on the inner wall of the air inlet 12.

[0030] The scraper 21 is fixed to the rectangular plate 13 by a protrusion, and the scraper 21 is in complete contact with the inner wall of the air inlet 12. In this way, when cleaning snow, the scraper 21 can fit against the inner wall of the air inlet 12. As the rectangular plate 13 slides, the snow attached to the wall is completely scraped away, avoiding snow residue accumulation. At the same time, the complete contact design can effectively eliminate cleaning dead corners.
