As shown in fig. 1, the water gas control valve set of the present invention is located at the rear side of the endoscope handle.
As external support, it only needs a cabinet for holding the air release pump and the first container, the second container cooperates. The air pump is connected with the first air pipe to serve as an air inlet pipe, and the air outlet is connected with the second air pipe and the third air pipe after passing through the tee joint. The first container is used as a vacuum container and also used as a liquid suction collecting container, and the second container is a water storage container and is respectively connected with the second air pipe and the first water pipe.
As a connection portion with the endoscope tube, wherein the fourth water tube is connected with the fifth air tube through a tee joint and then enters a main channel of the endoscope tube, the third water tube enters a sub channel of a cleaning lens of the endoscope tube, and the second liquid suction tube is connected with a liquid suction channel of the endoscope tube.
It mainly comprises a first valve body, a second valve body and a third valve body.
The first valve body mainly controls the liquid to enter the main channel or the auxiliary channel of the cleaning lens, and simultaneously provides the function that the air outlet channel is closed with the main channel, so that the air pressure generated by the air pump is forced to press water in the second container. The valve core of the first valve body is a solid valve core, and the top is a button. The first valve body is provided with two inlets which are respectively connected with the first water pipe and the third air pipe, and three outlets which are respectively connected with the second water pipe, the third water pipe and the fourth air pipe.
The main function of the second valve body is to switch liquid suction or air suction, the air inlet of the second liquid suction pipe or the first container is communicated with the atmosphere, the function of the second liquid suction pipe or the air inlet of the first container is controlled to switch, and the outlet of the first valve body is connected with the first liquid suction pipe.
The third valve body has the main functions of gas-liquid switching control of the main channel and directly discharging the compressor into the air, and is provided with two inlets which are respectively connected with the second water pipe and the fourth air pipe, and three outlets which are respectively communicated with the fourth water pipe, the fifth air pipe and the atmosphere.
The valve cores of the second valve body and the third valve body are hollow structures, the top of the valve core is used as a button, and the bottom of the valve core is communicated with the atmosphere. The second valve body sucks in air, and the third valve body exhausts air. The hole on the valve core is blocked, and the communication relationship between the inside and the atmosphere can be controlled. Thereby realizing vacuumizing, introducing high-pressure gas into a human body, or introducing generated pressure water into a main channel of an endoscope tube or a secondary channel of a cleaning lens.
As shown in figure 2, in the initial state, the air pump is started, the first valve body, the second valve body and the third valve body are in a free state (namely, the valve core is not pressed by fingers and the valve core hole is not blocked), the first container is not pressurized, the second container is not vacuumized, the fifth air pipe has resistance and is not discharged, the air channel is sucked from the center hole of the second button along the arrow direction, the air is discharged to the atmosphere through the air pump, the first container and the second container from the center hole of the third button, the whole air channel is almost pressureless, the air pressure in the second container is atmospheric pressure, and the system related to water is actually in a non-working state.
In the blowing state, as shown in fig. 3, the air pump is started, the finger seals the outlet of the third button but does not push the valve core of the third button, the first valve body and the second valve body are in a free state, the second container is not in vacuum, a certain pressure is generated in the first container, the air channel flows out from the fifth air pipe along the arrow direction, the main channel blowing is realized, and the focus blowing is realized.

As shown in fig. 5, in the auxiliary water spraying state, the air pump is started, the first button is pressed by a finger and the valve core is pushed to the limit position, and as the fourth air pipe is not communicated, the pressure in the first container is increased, water is pressed into the first water pipe, flows out of the third water pipe through the third valve body, and auxiliary water spraying, namely lens flushing, is realized.
As shown in figure 6, in the vacuumizing state, the air pump is started, the finger seals the outlet of the second button but does not push the second valve core, the first valve body and the third valve body are in a free state, the first container is pressureless, the second valve body is in a closed state, after a period of time, the second valve core is blocked, no air is input from the atmosphere, and can not suck air from a focus, so that the second container gradually forms a vacuum state under the condition that the air pump is in air suction, and real-time air pressure is displayed by a pressure gauge on the second container.
The liquid suction state is shown in fig. 7, namely, after the second container forms a vacuum state, a finger presses the second and the button to push the valve core of the second button to the limit position, at the moment, the air pump, the first air pipe, the first liquid suction pipe, the second valve body and the second liquid suction pipe are communicated, the first valve body and the third valve body are in a free state, the first container is pressureless, and liquid in a human body is sucked into the second container through the second liquid suction pipe.
After the liquid suction is finished, all fingers are loosened, the valve core of the second valve body returns to the original position under the action of the spring, the liquid suction is stopped, and air suction is started to the atmosphere from the valve core of the second valve body, the whole water-air system returns to the initial state, and the first container returns to normal atmospheric pressure.
