Abstract
Description
Technical Field
[0001] This utility model relates to the field of ventilation structure technology, and in particular to a ventilation structure for building design. Background Technology
[0002] The purpose of building ventilation structures is to ensure good air quality, temperature, and humidity inside the building and to provide a comfortable living or working environment. The design of ventilation structures requires comprehensive consideration of multiple factors such as the building's geographical location, climate conditions, building use, and pedestrian traffic. A good ventilation structure can provide a comfortable and healthy indoor environment.
[0003] In existing ventilation structures, filters are usually installed not far from the air vent to block dust in the duct and the air, thus preventing external dust from entering the room. However, when the filter is used for filtering for a long time, dust will accumulate on it and it needs to be cleaned. But the way to clean it is to remove the filter and clean it separately, which is very inconvenient, especially in places with high ceilings. Based on this, this utility model is proposed. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a building ventilation structure that can overcome or at least partially solve the above problems.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A building ventilation structure includes a shell and further includes: a ventilation opening on one side of the shell; a metal frame slidably connected inside the shell; a filter screen fixedly connected to the metal frame; and a brush rod slidably connected to the shell; a rotating cover plate rotatably connected inside the shell; and a cleaning rod slidably connected inside the shell; when the metal frame and the filter screen move upward, the brush rod scrapes off the dust on the filter screen, the rotating cover plate opens, and the cleaning rod sweeps the fallen dust out of the interior of the shell.
[0007] Preferably, a support plate is fixedly connected inside the housing, and a stroke push rod is fixedly connected to the support plate.
[0008] Furthermore, an extension rod is fixedly connected to the metal frame, and another part of the extension rod is rotatably connected to a second rotating link. The other end of the second rotating link is rotatably connected to the output end of the stroke push rod.
[0009] Preferably, a limiting rod is fixedly connected inside the housing to restrict the sliding path of the metal frame.
[0010] Preferably, an extension slide rod is fixedly connected to the rotating cover plate, and an extension slide groove is provided on the extension slide rod, and the metal frame is slidably connected in the extension slide groove.
[0011] Preferably, a sliding groove is provided inside the housing, a cleaning rod is slidably connected in the sliding groove, a connecting shaft is fixedly connected to the cleaning rod, a first rotating connecting rod is rotatably connected to the connecting shaft, and the other end of the first rotating connecting rod is rotatably connected to the rotating cover plate.
[0012] Preferably, a support rod and a guide block are fixedly connected inside the housing, the brush rod is slidably connected to the guide block, and a compression spring is connected between the brush rod and the support rod.
[0013] Preferably, an L-shaped locking block is fixedly connected to the bottom of the housing, and a collection shell is slidably connected to the L-shaped locking block.
[0014] Compared with the prior art, this utility model provides a building ventilation structure with the following advantages:
[0015] 1. The building is designed with a ventilation structure in which a stroke push rod drives the second rotating link to rotate, thereby causing the second rotating link to drive the extension support rod connected to it to rise, which in turn causes the metal frame and filter screen to rise, allowing the brush rod to scrape the dust on the filter screen to the bottom of the housing, thus completing the cleaning of the filter screen.
[0016] 2. The building is designed with a ventilation structure. When the moving metal frame rises, it will cause the extension slide rod and the rotating cover to flip upward, opening the through hole at the bottom of the shell. At the same time, the metal frame pulls the first rotating connecting rod and the cleaning rod to collect and scrape off the dust at the bottom of the shell.
[0017] The parts of this device not covered herein are the same as or can be implemented using existing technology. This utility model can automatically clean the filter screen and collect the cleaned dust to prevent the dust that falls off during cleaning from re-adhering to the filter screen.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0028] Example 1: Refer to Figures 1-7 A building ventilation structure includes a shell 1, and further includes: a ventilation opening 11 on one side of the shell 1; a metal frame 3 slidably connected inside the shell 1; a filter screen 31 fixedly connected to the metal frame 3; and a brush rod 41 slidably connected to the shell 1; a rotating cover 2 rotatably connected inside the shell 1; and a cleaning rod 5 slidably connected inside the shell 1; when the metal frame 3 and the filter screen 31 move upward, the brush rod 41 scrapes off the dust on the filter screen 31, the rotating cover 2 is opened, and the cleaning rod 5 sweeps the fallen dust out of the interior of the shell 1.
[0029] In this invention, the end of the housing 1 opposite to the vent 11 can be directly connected to a centralized air supply duct or directly installed with an air supply device such as an exhaust fan to supply air into the room. Regardless of the air supply method, after long-term use, the side of the filter screen 31 facing away from the vent 11 will accumulate a large amount of dust. The metal frame 3 drives the filter screen 31 to move upward, so that the brush rod 41 can scrape the dust on the filter screen 31 to the bottom of the housing 1. During the process of the metal frame 3 rising, the rotating cover 2 will flip open, and the cleaning rod 5 will move to push the dust at the bottom of the housing 1 to the outlet where the housing 1 connects to the outside and discharge the dust.
[0030] Example 2: Refer to Figures 1-7 Similar to Embodiment 1, but with a further improvement: a support plate 14 is fixedly connected inside the housing 1, and a stroke push rod 6 is fixedly connected to the support plate 14; an extension support rod 32 is fixedly connected to the metal frame 3; another part of the extension support rod 32 is rotatably connected to a second rotating connecting rod 61, and the other end of the second rotating connecting rod 61 is rotatably connected to the output end of the stroke push rod 6; a limit rod 33 is fixedly connected inside the housing 1 to limit the sliding path of the metal frame 3; an extension slide rod 21 is fixedly connected to the rotating cover plate 2, and an extension slide groove 211 is provided on the extension slide rod 21; the metal frame 3 slides... Connected within the extension chute 211, the housing 1 has an internal sliding groove 52. A cleaning rod 5 is slidably connected within the sliding groove 52. A connecting shaft 51 is fixedly connected to the cleaning rod 5. A first rotating connecting rod 22 is rotatably connected to the connecting shaft 51. The other end of the first rotating connecting rod 22 is rotatably connected to the rotating cover plate 2. A support rod 4 and a guide block 43 are fixedly connected within the housing 1. A brush rod 41 is slidably connected to the guide block 43. A compression spring 42 is connected between the brush rod 41 and the support rod 4. An L-shaped locking block 12 is fixedly connected to the bottom of the housing 1. A collection shell 13 is slidably connected to the L-shaped locking block 12.
[0031] In this utility model, a limiting groove is formed between the limiting rod 33 and the housing 1, thereby restricting the metal frame 3 to only be able to move up and down. The stroke push rod 6 pushes the second rotating connecting rod 61 to rotate, thereby enabling the second rotating connecting rod 61 to drive the extension support rod 32 rotatably connected to it to rise, thereby causing the metal frame 3 and the filter screen 31 to rise. Similarly, when the stroke push rod 6 pulls the second rotating connecting rod 61 to reset, the metal frame 3 and the filter screen 31 descend.
[0032] Two sliding rods are fixedly connected to the bottom sides of the metal frame 3. The metal frame 3 is slidably connected to the extension slide groove 211 through the sliding rods. The other end of the rotating cover plate 2 is rotatably connected to the housing 1. When the metal frame 3 rises, it will drive the extension slide rod 21 and the rotating cover plate 2 to flip upward, thereby opening the through hole at the bottom of the housing 1.
[0033] When the rotating cover 2 is flipped, the first rotating connecting rod 22, which is rotatably connected to its bottom, moves together with the rotating cover 2. The first rotating connecting rod 22 will pull the connecting shaft 51, which is rotatably connected to it, to move. Under the limiting action of the sliding groove 52, the sweeping rod 5 moves along the bottom of the housing 1 and collects and scrapes the dust at the bottom of the housing 1. The bottom of the sweeping rod 5 can be made of a sponge-like material with a certain deformation ability, so that the bottom of the sweeping rod 5 is in closer contact with the housing 1.
[0034] A compression spring 42 is provided between the brush rod 41 and the support rod 4, so that the brush rod 41 can always be in contact with the filter screen 31, and the guide block 43 can ensure the movement path of the brush rod 41.
[0035] The collection shell 13 has an L-shaped slot, which allows the collection shell 13 to be locked onto the L-shaped locking block 12 by sliding from the side. The collection shell 13 can collect the dust pushed out by the sweeping rod 5. When it is necessary to clean the collection shell 13, simply slide the collection shell 13 to completely disengage it from the L-shaped locking block 12 to remove the collection shell 13.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
