DETAILED DESCRIPTION

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] This application discloses a ventilation device for a building.

[0035] Reference Figure 1 The ventilation device includes a ventilation duct 1, several connecting pipes 2 and several shock-absorbing supports 3. A fan is installed on the top of the ventilation duct 1 to increase the airflow speed inside the ventilation duct 1. One end of the connecting pipe 2 is connected to the ventilation duct 1 and the other end is inserted into the house, so that the air inside the ventilation duct 1 flows into the house through the connecting pipe 2. The shock-absorbing supports 3 fix the ventilation duct 1 to the exterior wall of the house and provide shock absorption for the ventilation duct 1.

[0036] See Figure 1 and Figure 2 The ventilation duct 1 has several ventilation openings 11 on its side wall. The ventilation openings 11 correspond to several connecting pipes 2. Each floor of the building has a pipe opening. One end of the connecting pipe 2 is inserted into the ventilation opening 11, and the other end is inserted into the pipe opening of the building, so that the air in the ventilation duct 1 can flow into the connecting pipe 2 and then into the building through the connecting pipe 2.

[0037] See Figure 3 Each shock-absorbing support 3 includes a fixing frame 31 and a shock-absorbing component 32. The fixing frame 31 is installed on the ventilation duct 1, and the shock-absorbing component 32 is connected to the fixing frame 31 and installed on the exterior wall of the building, thereby providing support for the ventilation duct 1.

[0038] See Figure 3 and Figure 4 Specifically, the fixing frame 31 includes a connecting frame 33 and two inclined support plates 34. The connecting frame 33 is formed by two half rings spliced ​​together by screws. The connecting frame 33 is fixedly sleeved on the outside of the ventilation pipe 1. One end of the inclined support plate 34 is fixedly connected to the connecting frame 33, and the other end is connected to another inclined support plate 34. The two inclined support plates 34 and the connecting frame 33 form a stable triangular structure.

[0039] To ensure a more stable connection between the connecting frame 33 and the ventilation pipe 1, a rubber pad 4 is provided between the connecting frame 33 and the ventilation pipe 1. During installation, the rubber pad 4 is first attached to the outer wall of the ventilation pipe 1, and then the connecting frame 33 is placed over the ventilation pipe 1. The connecting frame 33 presses the rubber pad 4 tightly, and the pressed rubber pad 4 releases elasticity to the connecting frame 33 and the ventilation pipe 1, making the connecting frame 33 more stable outside the ventilation pipe 1. Furthermore, when the ventilation pipe 1 vibrates, the rubber pad 4 can alleviate some of the vibration, reducing the vibration transmitted from the ventilation pipe 1 to the connecting frame 33.

[0040] Meanwhile, the ventilation pipe 1 is provided with an annular flange 12 made of metal and fixed to the outer wall of the ventilation pipe 1 by welding, and the connecting frame 33 has an annular groove 331 for embedding the annular flange 12; when the connecting frame 33 is installed, the annular flange 12 of the ventilation pipe 1 is embedded in the annular groove 331 of the connecting frame 33, so that the connecting frame 33 is not easy to move up and down after being installed on the ventilation pipe 1.

[0041] Referring to Figure 5 With Figure 6 The damping assembly 32 comprises a top plate 35, a bottom plate 36 and a damping spring 37, the damping spring 37 is located between the top plate 35 and the bottom plate 36, and the two ends of the damping spring 37 are fixedly connected with the top plate 35 and the bottom plate 36 respectively; the top plate 35 is fixedly connected with the inclined support plate 34 through a screw, and the bottom plate 36 is connected with the outer wall of the house through an expansion bolt. In actual installation, the two inclined support plates 34 are connected with the two damping assemblies 32 respectively, the two damping assemblies 32 are arranged obliquely, and the two damping assemblies 32 form a stable triangular structure with the outer wall of the house.

[0042] When the ventilation pipe 1 vibrates, the vibration is transmitted to the connecting frame 33, the inclined support plate 34 and the damping assembly 32 in sequence, after being transmitted to the damping assembly 32, the damping spring 37 of the damping assembly 32 is compressed and then rebounds, thereby offsetting a part of the vibration, so that the vibration transmitted to the outer wall of the wall is reduced.

[0043] The damping assembly 32 further comprises two side plates 38, the two side plates 38 are both located between the top plate 35 and the bottom plate 36, and the damping spring 37 is protected by the side plates 38. The side plate 38 comprises an upper plate 381 and a lower plate 382, the upper plate 381 is fixedly connected with the top plate 35, the lower plate 382 is fixedly connected with the bottom plate 36, and the upper plate 381 and the lower plate 382 are slidingly connected; when the damping spring 37 is compressed, the upper plate 381 and the lower plate 382 can move relatively.

[0044] Specifically, the upper plate 381 has a sliding block 383, and the lower plate 382 is provided with a sliding groove 384 for sliding of the sliding block 383; in normal state, the sliding block 383 is located in the sliding groove 384, and when the ventilation pipe 1 vibrates and the damping spring 37 is compressed, the sliding block 383 moves in the sliding groove 384.

[0045] In order to provide the damping capacity of the damping assembly 32, a buffer spring 385 is arranged in the sliding groove 384, the compression direction of the buffer spring 385 is the same as the moving direction of the sliding groove 384, and the end of the buffer spring 385 is fixedly connected with the end of the sliding block 383 in the sliding groove 384 by welding. When the sliding block 383 moves in the sliding groove 384, the sliding block 383 extrudes the buffer spring 385, and the elastic force of the buffer spring 385 is sequentially transmitted to the sliding block 383, the upper plate 381 and the top plate 35, thereby providing the damping capacity of the damping assembly 32, and at the same time, the sliding block 383 can be stabilized in the sliding groove 384.

[0046] The implementation principle of the ventilation device of the building house according to the embodiment of the application is as follows: when the ventilation pipe 1 vibrates, the vibration of the ventilation pipe 1 is transmitted to the connecting frame 33, the connecting frame 33 is transmitted to the inclined supporting plate 34, the inclined supporting plate 34 is transmitted to the damping assembly 32, and the vibration is slowed down by the damping assembly 32, so that the vibration is not easily transmitted to the outer wall of the house.

[0047] The above are the preferred embodiments of the application, and do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered in the protection scope of the application.
