A ventilation structure of a green building

Abstract

This utility model discloses a ventilation structure for green buildings, relating to the field of ventilation structure technology. It includes a ventilation duct, a filter assembly, and a building structure. The outer surface of the filter assembly slides through the interior of the ventilation duct. This utility model involves flipping a first frame plate to 90 degrees and pushing it, allowing the filter screen inside the first frame plate to enter the ventilation duct. At this time, the filter screen in the second frame plate is removed. The operator then uses a cleaning assembly to clean impurities from the surface of the filter screen in the second frame plate with a wire brush. Subsequently, the removed second frame plate is flipped and positioned using an L-shaped rod in conjunction with a rear positioning plate. This structural cooperation not only eliminates the cumbersome disassembly and assembly process of the filter screen, making operation simpler and easier, but also effectively cleans surface impurities from the filter screen, ensuring that a filter screen is always present in the ventilation duct, thereby effectively filtering the air in the ventilation duct.

Description

Technical Field

[0001] This utility model relates to the field of ventilation structure technology, specifically to a ventilation structure for green buildings. Background Technology

[0002] Green building refers to high-quality buildings that, throughout their entire life cycle, conserve resources, protect the environment, reduce pollution, and provide people with healthy, suitable, and efficient living spaces, maximizing the harmonious coexistence of humans and nature. Green buildings rely on ventilation structures to facilitate the exchange of indoor and outdoor air. Green building ventilation structures are divided into natural ventilation and mechanical ventilation. Their function is to directly or after purification exhaust stale indoor air to the outside and introduce fresh air to maintain indoor air quality that meets hygiene standards. Typically, urban buildings use ductwork for ventilation.

[0003] The existing technology has the following problems: In existing ventilation systems, ventilation ducts facilitate the transport and circulation of outside air into the room, while internal removable filters ensure effective air filtration, filtering impurities such as particulate matter and floating particles from the air.

[0004] After prolonged use, operators need to periodically remove the filter from the ventilation duct for cleaning. Once clean, it is then reinstalled. This process is not only tedious and time-consuming, but also inconvenient for operators. Furthermore, during the removal and cleaning of the filter, the inside of the ventilation duct is without a filter. If a draft occurs outside, some impurities may be blown directly into the room, resulting in ineffective filtration.

[0005] Therefore, we need a green building ventilation structure to solve the above problems. Utility Model Content

[0006] This invention provides a ventilation structure for green buildings to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A ventilation structure for a green building includes a ventilation duct, a filter assembly, and a building structure. The outer surface of the filter assembly is slidably connected through the interior of the ventilation duct. Positioning plates are fixedly connected to the front, rear, and right sides of the ventilation duct. The filter assembly includes a first frame plate and a second frame plate, which are movably connected to each other and form an L-shape. Filter screens are fixedly connected to the inner sides of both the first and second frame plates. Cleaning components are slidably connected to the outer surfaces of both the first and second frame plates. Blocking blocks are fixedly connected to the right side of the first frame plate and the upper and lower surfaces of the rear side of the second frame plate.

[0008] A further improvement of this utility model is that the surface mounting structures in the first frame plate and the second frame plate are the same.

[0009] A further improvement of this utility model is that: the right side of the first frame plate is provided with grooves on both the front and back sides, and the interior of the grooves is in a straight line with the surface of the filter screen.

[0010] A further improvement of the present invention is that both cleaning components include a third frame plate, and wire brushes are fixedly connected to the inner opposite surfaces of the third frame plate, with the opposite surfaces of the two wire brushes corresponding to the surface of the filter screen.

[0011] A further improvement of this utility model is that the lengths of the two wire brushes are the same as the height of the filter screen.

[0012] A further improvement of this utility model is that the outer surfaces of the two wire brushes correspond to the interior of the groove.

[0013] A further improvement of this utility model is that: an installation groove is provided in the middle of one side of the third frame plate, a positioning rod is fixedly connected to the middle of the inner wall of the installation groove, an L-shaped rod is slidably connected to the outer surface of the positioning rod, and the outer surface of the L-shaped rod is slidably connected to the inside of the installation groove.

[0014] A further improvement of this utility model is that the outer surface of the L-shaped rod in the vertical direction is inserted through the interior of the positioning plate.

[0015] A further improvement of this utility model is that: a columnar air outlet pipe is fixedly connected through the right side of the upper surface of the building, the outer surface of the air outlet pipe is fixedly connected through the upper left side of the building, a square cover is detachably connected to the right side of the outer surface of the air outlet pipe, a circular cover is threadedly connected to the lower part of the outer surface of the columnar air outlet pipe, and a wind cap is installed on the upper part of the outer surface of the columnar air outlet pipe.

[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: This invention provides a ventilation structure for green buildings. By flipping the first frame panel to 90 degrees and pushing it, the filter screen inside the first frame panel enters the ventilation duct. At this time, the filter screen in the second frame panel is removed. The operator uses a cleaning component to clean impurities from the surface of the filter screen in the second frame panel with a wire brush. Subsequently, the removed second frame panel is flipped over and positioned using an L-shaped rod in cooperation with a rear positioning plate. Through the cooperation of this structure, not only is the cumbersome disassembly and assembly of the filter screen eliminated, making operation simpler and easier to use, but it also effectively cleans impurities from the filter screen surface, ensuring that a filter screen is always present in the ventilation duct, thereby effectively filtering the air in the ventilation duct.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1: As Figures 1 to 8As shown, this utility model provides a ventilation structure for a green building, including a ventilation pipe 1, a filter assembly 2, and a building housing 8. The ventilation pipe 1 serves as a channel for air circulation, allowing outdoor air to be introduced into the building, providing a basic ventilation system. The outer surface of the filter assembly 2 is slidably connected through the interior of the ventilation pipe 1. The filter assembly 2 can filter the circulating air, remove impurities from the air, and improve the cleanliness of the air entering the room. Positioning plates 3 are fixedly connected to the front, rear, and right sides of the ventilation pipe 1. The design of the positioning plates 3 facilitates the use of the L-shaped rod 245.

[0022] Example 2: Figures 1 to 8 As shown, the filter assembly 2 includes a first frame plate 21 and a second frame plate 22. The first frame plate 21 and the second frame plate 22 form an L-shape, which facilitates subsequent use. The first frame plate 21 and the second frame plate 22 are movably connected, and their surface mounting structures are identical. Filter screens 23 are fixedly connected to the inner sides of both the first frame plate 21 and the second frame plate 22. These are the core components for filtering impurities. When air flows through the filter screens, impurities are trapped, and clean air enters the building through the filter screens, achieving air purification.

[0023] Example 3: Figures 1 to 8 As shown, the cleaning assembly 24, which is slidably connected to the outer surfaces of the first frame plate 21 and the second frame plate 22, is used to periodically clean the impurities attached to the surface of the filter screen 23, so as to avoid the impurities clogging the filter screen holes and causing a decrease in ventilation efficiency. The third frame plate 241 provides mounting support for the wire brush 242, and the wire brush 242 is fixedly connected to the opposing surfaces of the third frame plate 241. The opposing surfaces of the wire brush 242 correspond to the surface of the filter screen 23. When the third frame plate 241 is pushed to slide along the frame plate, the wire brush 242 can clean the surface of the filter screen 23, brush off the attached impurities, and restore the ventilation and filtration performance of the filter screen 23. The lengths of the two wire brushes 242 are the same as the height of the filter screen 23. This structure is designed to facilitate the all-round cleaning of impurities in the filter screen 23. The outer surfaces of the two wire brushes 242 correspond to the interior of the groove 201. The correspondence between the wire brushes 242 and the groove 201 makes it easy to disassemble the fixing bolt in the blocking block 25 and slide the third frame plate 241 in alignment with the first frame plate 21. Then, the blocking block 25 can be fixed and limited by the fixing bolt. The groove 201 and the surface of the filter screen 23 are in a straight line, which facilitates the sliding cleaning of the wire brushes 242.

[0024] Example 4: Figures 1 to 8As shown, the mounting groove 243 is opened in the middle of one side of the third frame plate 241, and the positioning rod 244 is fixedly connected to the middle of the inner wall, providing sliding support for the L-shaped rod 245. The L-shaped rod 245 is slidably connected through the outer surface of the positioning rod 244. The outer surface of the L-shaped rod 245 is slidably connected to the inside of the mounting groove 243, and can slide up and down along the mounting groove 243 and the positioning rod 244. The function of the positioning rod 244 is to prevent the L-shaped rod 245 from separating from the mounting groove 243. The vertical outer surface of the L-shaped rod 245 is inserted through the inside of the positioning plate 3. This structure facilitates the limiting of the first frame plate 21 or the second frame plate 22 after flipping, and can also limit the cleaning component 24.

[0025] The blocking block 25 is fixedly connected to the upper and lower surfaces of the right side of the first frame plate 21 and the rear side of the second frame plate 22, and the blocking block 25 is installed and fixed by the design of the fixing bolt to prevent the cleaning component 24 from slipping off the frame plate.

[0026] Example 5: Figures 1 to 8 As shown, a columnar air outlet duct 4 is fixedly connected through the upper right side of the building 8. The columnar air outlet duct 4 facilitates the exhaust of air from the interior of the building 8. The outer surface of the ventilation duct 1 is fixedly connected through the upper left side of the building 8. A square cover 7 is detachably connected to the right side of the outer surface of the ventilation duct 1. The detachable connection is made by bolts. A circular cover 6 is threaded to the lower outer surface of the columnar air outlet duct 4. The design of the square cover 7 and the circular cover 6 makes it easy to close the ventilation duct 1 and the columnar air outlet duct 4 when not in use. A wind cap 5 is installed above the outer surface of the columnar air outlet duct 4. The wind cap 5 can exhaust indoor air. The wind cap 5 is existing technology.

[0027] Working principle: When in use, the round cover 6 and the square cover 7 are removed. Outdoor air flows into the building 8 through the ventilation pipe 1, and then is discharged through the columnar air outlet pipe 4 and the hood 5. When the outside air enters the ventilation pipe 1, it is first filtered by the filter screen 23 of the filter assembly 2. Impurities are trapped by the filter screen 23, and clean air enters the room.

[0028] The worker moves the L-shaped rod 245 upwards to separate it from the front positioning plate 3 and flips the first frame plate 21 ninety degrees. At this time, the first frame plate 21 and the second frame plate 22 are in a straight line. The worker pushes the first frame plate 21. When it is pushed to the appropriate position, the cleaning component 24 in the first frame plate 21 contacts and limits the contact with the surface of the ventilation pipe 1. The filter screen 23 in the first frame plate 21 enters the interior of the ventilation pipe 1, and the filter screen 23 in the second frame plate 22 moves out of the interior of the ventilation pipe 1, so that the ventilation pipe 1 always has a filter screen 23. The worker moves the cleaning component 24 in the second frame plate 22 so that the wire brush 242 cleans the impurities on the surface of the filter screen 23 in the second frame plate 22. After cleaning, the worker flips the second frame plate 22 to ninety degrees and contacts the surface of the ventilation pipe 1. Then, through the cooperation of the L-shaped rod 245 in the second frame plate 22 and the rear positioning plate 3, the flipped second frame plate 22 is limited. The structure is simple to set up and easy to use, and there is no need to disassemble the filter screen 23.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
