[0004] The disadvantages of the double-airbag oxygen bar room dedicated bar in the above-mentioned comparative document are: when the oxygen in the airbag is almost used up, the pressure in the airbag also decreases, making it difficult for the residual oxygen in the airbag to flow out automatically, thereby causing a waste of oxygen, and the carbon dioxide exhaled by the passenger is easy to enter the airbag when the airbag pressure drops, diluting the oxygen in the airbag and affecting the purity of the oxygen;

[0005] For this reason, we have designed a special bar counter for double-airbag oxygen bar rooms. Utility Model Content

[0006] The technical problem solved by the utility model is to provide a double-airbag oxygen bar room dedicated bar table which is highly practical, can be simply operated and has a relatively simple structure, thereby solving the problem that the residual oxygen in the airbag is difficult to flow out automatically as mentioned in the above background technology.

[0007] To achieve the above purpose, the utility model is implemented through the following technical solutions: a special bar for a double-airbag oxygen bar room, including a bar, a cavity is arranged inside the bar, a cover plate is fixedly connected to one side of the bar by bolts, a hydraulic rod is fixedly connected to one side of the cover plate, a push plate is fixedly connected to one end of the hydraulic rod, a rubber pad is fixedly connected to one side of the push plate, an airbag is attached to the surface of the rubber pad, an air outlet ring is connected to one side of the airbag, the air outlet ring passes through one side of the bar and is connected to a fixed pipe, and one end of the fixed pipe is connected to a transfer block.

[0008] Optionally, a pressure gauge body is connected through one side of the adapter block, and a catheter is connected through one end of the pressure gauge body, so that the pressure of the airbag can be checked by the pressure gauge body.

[0009] Optionally, one end of the conduit is connected to a cylinder, one side of the cylinder is provided with an air inlet, the air inlet is connected to the conduit, and the oxygen transported by the conduit enters the cylinder from the air inlet on one side of the cylinder.

[0010] Optionally, a spring is fixedly connected to the inner wall of the cylinder, a buffer rod is sleeved inside the spring for buffering, and a gasket is fixedly connected to one end of the spring. The spring can drive the gasket back to the limiting ring when the pressure in the airbag is low and it is difficult to output oxygen, thereby preventing external air from entering the airbag.

[0011] Optionally, the surface of the gasket is in contact with a limiting ring, and the gasket leaving the limiting ring can allow oxygen to flow to the gas pipeline. The surface of the limiting ring is connected to a cylinder.

[0012] Optionally, a circular hole is opened on the other side of the cylinder, and an air supply pipe is connected through the surface of the circular hole. The air supply pipe can be connected to an oxygen mask to allow passengers to breathe oxygen.

[0013] The utility model provides a double-airbag oxygen bar room dedicated bar counter, which has the following beneficial effects:

[0014] The double-airbag oxygen bar room special bar counter is provided with airbags, hydraulic rods, push plates, rubber pads, cylinders, springs and gaskets. After the pressure in the two airbags drops to the lowest, there is still residual oxygen in the airbags. At this time, the hydraulic rod is opened to push the push plates and rubber pads to squeeze the airbags, so that the residual oxygen in the airbags is squeezed out. At the same time, when the oxygen is squeezed out, it passes through the cylinder and pushes the gasket, so that the gasket leaves the limiting ring and the oxygen flows out to the air pipe. After the oxygen can no longer be squeezed out, the gasket is pulled back to the limiting ring by the spring, so that the carbon dioxide exhaled by the passengers and the external air flow into the airbags, which is convenient for the subsequent filling of the airbags with oxygen, reduces the waste of residual oxygen in the airbags, and improves the oxygen utilization rate of the device.
