Abstract

This utility model provides a dustproof and waterproof cover for the air outlet of a fresh air system, including a side-mounted air supply pipe and an air outlet plate set on top of it, as well as a cover. A top frame is glued to the top of the cover, and a hinge is fixedly provided on the bottom right side of the top frame. The bottom of the hinge is fixedly connected to the top right end of the thin plate damper. The waterproof bend structure design of the cover prevents condensation from appearing on the outside of the cover and flowing to the air outlet plate. Combined with the right-larger-left-smaller and bottom-sloping structural features of the mounting hole, and the air outlet of the side-mounted air supply pipe and the air outlet plate working together to deliver air outward, it effectively prevents condensation appearing on the right side of the cover or on the inner wall of the mounting hole from flowing to the air outlet plate, and prevents external condensation mixed with dust from entering the side-mounted air supply pipe through the air outlet, thus achieving dustproof treatment of the air outlet end of the side-mounted air supply pipe.

Description

Technical Field

[0001] This utility model mainly relates to the field of fresh air system technology, specifically to a dustproof and waterproof cover for the air outlet of a fresh air system. Background Technology

[0002] In a fresh air system with a floor-mounted air supply design, the side-mounted air supply duct assembly installed on the wall is prone to dust accumulation at the air outlet due to the dust adsorbed by the wall decoration materials. When condensation occurs at the air outlet due to prolonged low-temperature air supply and indoor humidity, the surface of the air outlet is easily stained with a mixture of dust and water. As the water flows downward under gravity, it is very easy for sewage to flow into or enter the air outlet or the gap between the air outlet and the damper.

[0003] The inventor proposes a dustproof and waterproof cover for the air outlet of a fresh air system. An additional component is added to the outside of the air outlet of the side-mounted air supply duct assembly to extend the air outlet outward. The component is designed to protrude from the wall, and the outward-extending component also needs to be designed with a waterproof bend to prevent condensate from the outside of the equipment from flowing into the side-mounted air supply duct. Combined with a thin plate damper set on the outside of the outward-extending component, the dustproof and waterproof design protection of the air outlet of the side-mounted air supply duct is achieved.

[0037] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the utility model will be more thorough and complete.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] See attached document Figure 1-10 This utility model provides a dustproof and waterproof cover for the air outlet of a fresh air system, including a side-mounted air supply pipe 1 and an air outlet plate 2 set on its top, and also includes a cover 3. A top frame 5 is glued to the top of the cover 3, and a hinge 6 is fixedly provided on the bottom right side of the top frame 5. The bottom of the hinge 6 is fixedly connected to the top right end of the thin plate damper 7.

[0041] In this embodiment, the air outlet plate 2 has multiple air outlets 21 from the front to the rear. The front and rear ends of the right side of the air outlet plate 2 are fixed with hanging ears 22, and the opposite sides of the two hanging ears 22 are detachably snapped to the front and rear ends of the cover 3.

[0042] In the installation of the fresh air system, the side-mounted air supply duct 1 needs to be installed against the wall on the facade of the building. At this time, the air outlet 21 of the air outlet plate 2 is parallel to the ground. The design of the hanging ears 22 on the outside of the air outlet plate 2 makes it convenient for users to install the cover 3 on the right side of the air outlet plate 2. The cover 3 and the thin plate damper 7 work together to complete the dustproof shielding and waterproof protection of the air outlet 21 of the air outlet plate 2.

[0043] In this embodiment, a waterproof bend 31 bent to the left is fixed on the bottom right side of the cover 3. Multiple assembly holes 32 for matching air outlets 21 are opened from the front to the rear of the cover 3. The diameter of the right side of the assembly hole 32 is larger than that of the left side, and the bottom hole wall extends downward to the right. A first magnetic absorbing piece 33 is bonded to the bottom right side of the cover 3. The first magnetic absorbing pieces 33 are arranged in pairs. The right side of the other first magnetic absorbing piece 33 is bonded to the bottom left side of the thin plate damper 7. The gap between the cover 3 and the air outlet plate 2 is filled with polyurethane heat insulation board 4.

[0044] The waterproof bend 31 structure of the cover 3 prevents condensation from appearing on the outside of the cover 3 and flows to the air outlet plate 2. Combined with the right-larger-left-smaller and bottom-sloping structural features of the assembly hole 32, and the cooperation between the side air supply pipe 1 and the air outlet 21 of the air outlet plate 2 to deliver air outward, it effectively prevents condensation appearing on the right side of the cover 3 or condensation appearing on the inner wall of the assembly hole 32 from flowing to the air outlet plate 2. It also prevents external condensation mixed with dust from entering the side air supply pipe 1 through the air outlet 21, thus achieving dustproof treatment at the air outlet end of the side air supply pipe 1.

[0045] In this embodiment, an adhesive layer is provided between the bottom left end of the top frame 5 and the top of the cover 3. This adhesive layer can be double-sided tape or glue.

[0046] The assembly between the top frame 5 and the cover 3 can be done with double-sided tape or glue, depending on the customer's needs. The adhesive structure design makes installation convenient.

[0047] In this embodiment, a second magnetic absorbing piece 61 is fixedly provided on the left side of the bottom plate at the top and bottom of the hinge 6, and the horizontal distance between the center of the pivot of the hinge 6 and the top left side of the thin plate damper 7 is at least 4 mm.

[0048] The hinge 6 cooperates with the second magnetic plate 61. When the side air supply pipe 1 and the air outlet 21 stop supplying air, the attraction between the two second magnetic plates 61 and the two first magnetic plates 33 causes the two bottom plates of the hinge 6 at the top of the thin plate damper 7 to come close to each other, and the bottom of the thin plate damper 7 to fit with the bottom of the cover 3. This allows the thin plate damper 7 to seal the mounting hole 32 of the cover 3, thus completing the sealing of the air outlet 21 when the fresh air system stops supplying air.

[0049] When the fresh air system is in operation, the air pressure inside the side-mounted air supply duct 1 increases. This increased air pressure, through the air outlet 21 and the mounting hole 32, pushes the thin plate damper 7 to deflect around the pivot of the hinge 6, releasing the connection between the two first magnetic plates 33 and the two second magnetic plates 61. This exposes the air outlet 21 and the mounting hole 32, allowing the air supplied by the fresh air system inside the side-mounted air supply duct 1 to be smoothly discharged to the indoor floor, thus completing the ground air supply function in the ground air supply and top-receive design of the fresh air system.

[0050] In this embodiment, a deflection area 71 is fixedly provided on the bottom left side of the thin plate damper 7, which deflects to the left. The left side of the thin plate damper 7 is attached to the right side of the cover 3. The opening and closing angle of the thin plate damper 7 outside the cover 3 with the pivot of the hinge 6 as the center is 0°-56°. The distance between the top right side and the bottom left side of the thin plate damper 7 is at least 6 mm.

[0051] The design of the deflection area 71 of the thin plate damper 7, as well as the assembly of the top right side of the thin plate damper 7 with the hinge 6 and the counterweight design of the first magnetic suction plate 33 on the bottom left side, ensure that the thin plate damper 7 can deflect to the left under the action of gravity with the pivot of the hinge 6 as the center to the adsorption distance of the first magnetic suction plate 33 or the second magnetic suction plate 61.

[0052] It should be noted that as the air pressure of the fresh air system and the air velocity at the air outlet 21 increase, the opening angle of the thin plate damper 7 outside the housing 3 will also increase positively. The thin plate damper 7 is passively opened outside the housing 3.

[0053] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
