Description

Technical Field

[0001] The utility model belongs to the technical field of air film buildings, and particularly relates to a ventilation device for air film buildings. Background Technique

[0002] An air film building is a modern building form that uses a special inflatable film structure to form the external shape of the building. This building structure is usually supported by one or more airtight film layers made of polytetrafluoroethylene (PTFE) or other similar materials, and is equipped with a set of intelligent electromechanical equipment inside to provide positive pressure of air inside the air film building, and is a building structure system that supports the main body of the building.

[0003] Due to the slow working rate of the air supply equipment when the internal air pressure is normal in the existing air film building, the air flow inside the air film building is slow. And if the internal air does not flow for a long time, impurities in the air are likely to suspend inside the air film building, which will lead to a decline in air quality after long-term use. Therefore, ventilation equipment is needed to ventilate the inside of the air film building. However, most of the existing ventilation devices can only exhaust and supply air to the inside separately, resulting in a slow air flow and circulation speed inside, and unable to select a suitable ventilation method according to needs, with a poor use experience. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that most of the existing ventilation devices can only exhaust and supply air to the inside separately, resulting in a slow air flow and circulation speed inside, and unable to select a suitable ventilation method according to needs.

[0005] To solve the above technical problem, the technical solution provided by the utility model is a ventilation device for an air film building, including a ventilation box. An acoustic absorption layer is arranged inside the ventilation box. L-shaped ventilation pipes are arranged on both sides inside the ventilation box, and the two sides of the ventilation pipes are symmetrically arranged. A connection cover is arranged at the top of the ventilation pipe. A first filter plate is arranged at the connection cover. The tail of the L-shaped structure of the ventilation pipe is located on the side of the ventilation box, and a fan is arranged at the connection between the ventilation pipe and the ventilation box. A second filter plate is inserted outside the fan of the ventilation box. The two ventilation pipes are connected by a return air pipe. A first solenoid valve is arranged on the ventilation pipe, and a second solenoid valve is arranged on the return air pipe.

[0006] Preferably, the acoustic absorption layer is a polyester fiber acoustic absorption board.

[0007] Preferably, the connection cover is in a funnel-shaped structure, and the diameter gradually increases from the ventilation pipe outwards.

[0008] Preferably, the first filter plate is composed of a plastic filter screen and non-woven fabric adhered together, and the non-woven fabric is located inside the first filter plate. The second filter plate has the same structure as the first filter plate.

[0009] Preferably, a controller is provided on one side in the middle of the ventilation box. A plurality of control buttons and an LED display screen are provided on the controller. Inside the controller, there are a control calculation module, a wireless module, and a power module that are electrically connected to each other. The control calculation module is electrically connected to a plurality of control buttons, the LED display screen, the fan, the first solenoid valve, and the second solenoid valve.

[0010] Preferably, the fan is communicated with the ventilation pipe, and the two fans are arranged oppositely on both sides of the ventilation box.

[0011] Preferably, a protective groove protruding from the outside of the ventilation box is provided on the outside of the ventilation box where the fan is located. An insertion slot is provided above the protective groove. The second filter plate matches the shape of the insertion slot and is inserted and fixed with the insertion slot.

[0012] Preferably, the first solenoid valve is located at the position between the return air pipe and the fan on the ventilation pipe.

[0013] The advantages of the present utility model compared with the prior art are as follows:

[0014] 1. By adjusting the operating states of the solenoid valve and the fan, this ventilation device can use the two ventilation pipes for simultaneous air supply and air extraction operations, or can choose to simultaneously perform air supply and air extraction operations, internal air circulation operations, etc. according to needs, increasing the speed of air circulation inside the air film building and improving the internal air.

[0015] 2. When extracting air, this ventilation device may suck sundries inside the air film building into the ventilation pipeline. By setting the first filter plate, this situation can be prevented, and the first filter plate and the second filter plate can be removed according to needs, so that the dust inside the air film building can be directly discharged.

[0016] 3. Through the sound-absorbing layer provided inside, this ventilation device can effectively reduce the noise generated by the fan during operation and improve the use experience. Description of the Drawings
