Now people often go to places to play is the chess room, and the chess room has become a public place for public entertainment. However, the chess room is relatively closed, the ventilation volume is limited, there are many indoor smokers, and the smoke concentration in the air is high, which also causes the surrounding people to be passively exposed to second-hand smoke, mixed with PM2.5 particles, formaldehyde, benzene series, bacteria, mold, fungi and other harmful substances. If a person stays in such an environment for a long time, it can cause lung cancer, blood vessel obstruction and other diseases, and the degree of harm to the body is very large. Air is the only thing that accompanies us 24 hours a day but cannot be seen. Its influence on the human body is subtle and accumulates over time.

[0005] The air purification device comprises: a purification pipeline, the purification pipeline penetrates the wall, that is, the wall divides the purification pipeline into three parts, an indoor purification pipeline, a wall purification pipeline and an outdoor purification pipeline; a protective cover plate is arranged on the open end of the outdoor purification pipeline; the wall purification pipeline is fixed in the wall by a threaded fixing ring, thereby fixing the entire purification pipeline firmly; a harmful gas purification unit and a particle purification unit are arranged in the purification pipeline, the harmful gas purification unit can remove harmful gases such as formaldehyde and odors, and the particle purification unit can remove particles such as PM10 and PM2.5, and can also kill viruses and bacteria.

[0006] When the indoor air is in a positive pressure state during operation: the indoor air can pass through the purification pipeline to the harmful gas purification unit and the particle purification unit, and then be discharged from the gap between the open end of the outdoor purification pipeline and the protective cover plate after purification; when the indoor air is in a negative pressure state: outdoor air can pass through the gap between the protective cover plate and the open end of the outdoor purification pipeline to reach the harmful gas purification unit and the particle purification unit, and then enter the indoor through the indoor purification pipeline after purification.

[0007] The above scheme can realize that indoor air and outdoor air can be freely exchanged, indoor oxygen can be supplemented, and carbon dioxide can be discharged.

[0008] The product formed by the technical scheme can be applied in the following scenarios

[0009] (1) Infectious disease room, for example: SARS room, new coronavirus room, can prevent infection to outdoor healthy people.

[0011] (3) Operating room: incision wound is easy to be infected and inflamed, and bacteria and viruses in outdoor air can be prevented from entering the room to infect the wound and cause inflammation.

[0012] (4) Delivery room: puerpera is easy to be infected and inflamed, and bacteria and viruses in outdoor air can be prevented from entering the room to infect the wound and cause inflammation.

[0025] Compared with the prior art, the present application has the beneficial effects that:

[0026] Firstly, in use, the invention utilizes a controller to operate a lifting device that lowers the housing as a whole, allowing it to protrude from the ceiling. The air purifier then purifies the indoor air, especially in game rooms, through a gas exhaust pipe and two gas inlet components. The first and second telescopic devices extend from the housing simultaneously, expanding the purifier's effective range and improving air purification quality. When maintenance is required, the housing can be lowered using the lifting device, allowing for easy access and maintenance. After maintenance, the housing is raised again using the lifting device. During this raising, an auxiliary lifting device vertically assists in raising the gas exhaust pipe, ensuring it is concealed within the ceiling. In summary, this invention can purify the air in large game rooms, improving air quality.

[0027] Secondly, this invention uses an electric push rod to drive the gripper to move horizontally. The gripper then picks up the gas discharge pipe. Subsequently, the lifting motor and coupling work together to drive the rotating shaft and the lifting gear to rotate around the axis of the rotating shaft. The lifting gear, through its engagement with the second tooth groove, drives the slide bar to rise. The slide bar drives the bearing plate and the gripper to rise synchronously. Afterward, the gripper stops working, and the lifting motor drives the gripper to move downward. Then, the previous action is repeated. This allows the gas discharge pipe to enter the ceiling synchronously when the housing rises, reducing the probability of damage to the entire device. Attached Figure Description
