[0002] Heating ventilation and air conditioning is a part of a building. Its full name in the subject classification is heating, gas supply, ventilation and air conditioning engineering, including three aspects: heating, ventilation and air conditioning. Functionally, it is also an essential part of future families. Among them, ventilation is the process of sending air into a room or exhausting air from a room, using outdoor air (referred to as fresh air or fresh wind) to replace the air in a building (referred to as indoor air). Usually, it is divided into natural ventilation and mechanical ventilation. At present, most of the ventilation devices used in heating ventilation and air conditioning engineering are mechanical ventilation, that is, the blower and the ventilation pipe cooperate with each other to achieve the purpose of air supply or exhaust. When the ventilation device sucks the outside air into the ventilation pipe;
[0003] In order to prevent dust from entering the interior of the ventilation device, a filter screen is generally provided at the dust inlet. However, after long-term use, there will be a lot of dust on the filter screen. During long-term use, the dust needs to be cleaned. During the period of cleaning the dust, the ventilation device cannot operate. Therefore, how to solve this problem is what we need to consider. Content of the Utility Model
[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose an efficient ventilation device based on heating ventilation and air conditioning engineering. During the use of the device, two sector-shaped nets are provided and can be replaced separately. Even after one net body is removed, the ventilation device can still operate normally.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] An efficient ventilation device based on heating ventilation and air conditioning engineering, including an air inlet pipe. A circular plate is arranged inside the air inlet pipe. A partition is fixedly connected to the left side of the circular plate. The partition and the circular plate divide the left end part inside the air inlet pipe into two ventilation spaces. Two sector-shaped nets are symmetrically arranged on the left side of the air inlet pipe. Arc-shaped connecting strips are fixedly connected to the outer sides of the two sector-shaped nets.
[0007] Preferably, each arc-shaped connecting strip is installed on the left side of the air inlet pipe through a plurality of mounting screws.
[0008] Preferably, the two sector-shaped nets are used to seal the left sides of the two ventilation spaces.
[0009] Preferably, two sector openings are symmetrically formed on the right side of the circular plate, and two sealing plates are symmetrically arranged to the right of the circular plate. On the left side of each of the two sealing plates, guide rods are symmetrically and fixedly connected. Each guide rod passes through the circular plate and is slidably connected to the corresponding circular plate.
[0010] Preferably, the left end of each guide rod contacts the right side of the corresponding sector mesh.
[0011] Preferably, the left side of each sealing plate is elastically connected to the circular plate by a plurality of springs, and each sealing plate cooperates with the corresponding sector opening.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] Two sector meshes are provided. When it is necessary to clean one of the sector meshes, only need to remove the mounting screws on the sector mesh, and then the sector mesh can be removed. After the sector mesh is removed, the ventilation opening at this place automatically closes and the other sector ventilation opening conducts ventilation, without affecting the ventilation of the whole device. After the sector mesh is installed later, the ventilation opening at this place ventilates automatically again. Description of the Drawings

[0019] Referring to Figures 1 - 3 , a highly efficient ventilation device based on a heating, ventilation, and air conditioning (HVAC) project, comprising an air inlet duct 1. A circular plate 6 is arranged inside the air inlet duct 1. A partition plate 5 is fixedly connected to the left side of the circular plate 6. The partition plate 5 and the circular plate 6 divide the left end part inside the air inlet duct 1 into two ventilation spaces;
[0020] Wherein, two sector-shaped meshes 2 are symmetrically arranged on the left side of the air inlet duct 1. Arc-shaped connecting bars 3 are fixedly connected to the outer sides of the two sector-shaped meshes 2. Each arc-shaped connecting bar 3 is installed on the left side of the air inlet duct 1 through a plurality of mounting screws 4. The two sector-shaped meshes 2 are used to seal the left sides of the two ventilation spaces;
[0021] Wherein, two sector-shaped openings 7 are symmetrically formed on the right side of the circular plate 6. Two sealing plates 9 are symmetrically arranged to the right of the circular plate 6. Guide rods 8 are symmetrically and fixedly connected to the left sides of the two sealing plates 9. Each guide rod 8 passes through the circular plate 6 and is slidably connected to the corresponding circular plate 6. The left end of each guide rod 8 contacts the right side of the corresponding sector-shaped mesh 2. The left side of each sealing plate 9 is elastically connected to the circular plate 6 through a plurality of springs 10. Each sealing plate 9 cooperates with the corresponding sector-shaped opening 7.
[0022] In the present utility model, during specific use, in Figure 1 State 1, the two sealing plates 9 are both in the retracted position and both seal the corresponding sector-shaped openings 7. At this time, the plurality of springs 10 are all in a stretched state;
[0023] When the sector-shaped mesh 2 needs to be cleaned, only the mounting screws 4 on the sector-shaped mesh 2 need to be removed, and then the sector-shaped mesh 2 can be removed. When the corresponding sector-shaped mesh 2 is removed, under the elastic action of the spring 10, the sealing plate 9 moves forward to seal the corresponding sector-shaped opening 7. At this time, the sealing is completed, and the other sector-shaped opening 7 continues to ventilate. That is, after the sector-shaped mesh 2 is removed, the ventilation of the entire device is not affected;
[0024] Subsequently, after the sector-shaped net 2 is installed, the installation will push the corresponding guide rod 8 backward, causing the corresponding sealing plate 9 to open the sector-shaped opening 7 again, so that the sector-shaped opening 7 is conducted again.
