DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 The utility model provides an adsorption type atmospheric gas collection device, comprising:

[0028] A hollow box body 1 with an opening on the upper side of the front wall, wherein a gas collection adsorption bag 7 and a liquid filling storage bag 6 containing liquid are respectively arranged on the upper and lower sides of the box body 1; the gas collection adsorption bag 7 and the liquid filling storage bag 6 are detachably connected and communicate with each other, and the upper part of the gas collection adsorption bag 7 is open;

[0029] The squeezing mechanism is arranged in the box body 1, and the squeezing mechanism is used to squeeze the liquid in the liquid filling storage bag 6 into the gas collection adsorption bag 7 through the connection between the gas collection adsorption bag 7 and the liquid filling storage bag 6.

[0030] When in use, move the device to the place where collection is required, push the squeezing mechanism upward, and push the liquid in the liquid filling storage bag 6 into the gas collection adsorption bag 7 until the gas collection adsorption bag 7 is filled with liquid; then move the device to the side a little (rollers can be installed on the lower surface of the box 1 to facilitate movement), and lower the squeezing mechanism to make the liquid in the gas collection adsorption bag 7 flow back into the liquid filling storage bag 6 until the liquid in the gas collection adsorption bag 7 is completely discharged, and the space where the gas collection adsorption bag 7 originally stored the liquid is replenished by air entering from the outside, thereby realizing the collection of air at that location. It should be explained that the liquid is a liquid that is insoluble or slightly soluble in air, and has no effect on air detection or the effect can be ignored, such as water.

[0031] From the analysis of the above structure, it can be known that: the adsorption-type atmospheric gas collection device stores liquid in a liquid-filled storage bag. When discharging gas, the liquid in the liquid-filled storage bag is squeezed into the gas collection adsorption bag through the squeezing mechanism, and the gas in the gas collection adsorption bag is completely discharged; when adsorbing and collecting gas, the squeezing mechanism descends, the water in the gas collection adsorption bag enters the liquid-filled storage bag, and the air enters the gas collection adsorption bag from the top to adsorb and collect the air.

[0032] At the same time, the adsorption-type atmospheric gas collection device, through the detachable connection between the gas collection adsorption bag and the liquid filling storage bag, after collecting gas once, the gas collection adsorption bag is removed and another gas collection adsorption bag is installed to carry out the next gas collection operation.

[0033] like Figure 2 As shown, the embodiment of the utility model provides an implementation method, the extrusion mechanism includes an electric telescopic push rod 11 arranged at the bottom of the inner cavity of the box body 1, a push plate 12 arranged on the upper side of the output end of the electric telescopic push rod 11, a power supply battery 5 located in the box body 1, and a control switch 2 arranged outside the box body 1; the push plate 12 is attached to the outer wall of the liquid filling storage bag 6, and the power supply battery 5 is electrically connected to the electric telescopic push rod 11 and the control switch 2. Analysis of the above structural structure shows that: the electric telescopic push rod 11 is controlled to extend or shorten by the control switch 2, and the power supply battery 5 can be controlled to switch on and off the power supply circuit of the electric telescopic push rod 11. When the telescopic end of the electric telescopic push rod 11 is extended, the push plate 12 can be pushed up, and the liquid in the liquid filling storage bag 6 is pushed upward. When the push plate 12 moves downward, under the action of gravity, the liquid in the gas collection adsorption bag 7 falls into the liquid filling storage bag 6.

[0034] like Figure 1As shown, the embodiment of the utility model provides an implementation method, an opening and closing door 3 is rotatably connected to the upper opening of the front wall of the box body 1 through a hinge, and a transparent window 4 is embedded in the middle of the opening and closing door 3. Analysis of the above structural structure shows that: when it is necessary to take out or replace the gas collection adsorption bag 7 in the box body 1, the opening and closing door 3 can be opened to operate, and the transparent window 4 can observe the situation inside the box.

[0035] like Figure 2 As shown, the embodiment of the utility model provides an implementation method, the upper opening and the lower side of the gas collection adsorption bag 7 are connected with a plug connector 9, the upper side of the liquid filling storage bag 6 is provided with a ferrule 8, and the liquid filling storage bag 6 is connected to the plug connector 9 on the lower side of the gas collection adsorption bag 7 through the ferrule 8. Analysis of the above structural structure shows that: the plug connector 9 on the upper side of the gas collection adsorption bag 7 is used to fix the upper part of the gas collection adsorption bag 7, and the plug connector 9 on the lower side of the gas collection adsorption bag 7 is used to connect with the ferrule 8.

[0036] like Figure 2 As shown, the embodiment of the utility model provides an implementation method, the inner wall of the ferrule 8 is embedded with a rubber sealing ring, and the rubber sealing ring is sleeved on the outer wall of the plug connector 9 on the lower side of the gas collection adsorption bag 7. Analysis of the above structural structure shows that: after the plug connector 9 on the lower side of the gas collection adsorption bag 7 is connected to the ferrule 8, the rubber sealing ring is squeezed and deformed, so that the plug connector 9 and the ferrule 8 are not easy to loosen, and a sealing effect is achieved.

[0037] like Figure 2 As shown, the utility model embodiment provides an implementation method, the inner cavity of the box body 1 is transversely provided with a partition 10, and the ring 8 is fixedly mounted on the partition 10. The partition 10 separates the gas collection adsorption bag 7 and the liquid filling storage bag 6. When the gas collection adsorption bag 7 is taken out and placed, it is not easy to touch the liquid filling storage bag 6, and it has a supporting and positioning function for the gas collection adsorption bag 7 and the liquid filling storage bag 6.

[0038] like Figure 3 As shown, the first connection method of connecting the plug connector 9 at the upper end of the gas collection adsorption bag 7 to the upper end of the inner cavity of the box body 1 is:

[0039] The upper outer wall of the plug connector 9 at the upper opening of the gas collection adsorption bag 7 is provided with a protrusion 13, and the upper inner part of the inner cavity of the box body 1 is provided with a card frame 14, and the card frame 14 is provided with a bayonet 15 adapted to the protrusion 13. The protrusion 13 is inserted into the card frame 14 through the bayonet 15, and then the protrusion 13 and the plug connector 9 are rotated so that the protrusion 13 and the bayonet 15 are staggered, so that the plug connector 9 at the upper opening will not be detached from the card frame 14.

[0040] like Figure 4As shown, the first connection method of connecting the plug connector 9 at the upper end of the gas collection adsorption bag 7 to the upper end of the inner cavity of the box body 1 is:

[0041] A magnet ring 16 is arranged on the upper side of the plug connector 9 of the upper opening of the gas collection adsorption bag 7, and an armature ring 17 corresponding to the position of the magnet ring 16 is arranged on the upper part of the inner cavity of the box body 1. The plug connector 9 is connected to the upper side of the inner part of the box body 1 by magnetic adsorption between the magnet ring 16 and the armature ring 17. The connection is quick and convenient. The use here requires that the liquid entering the gas collection adsorption bag 7 will not press down the gas collection adsorption bag 7 and the magnet ring 16 and detach from the armature ring 17.

[0042] like Figure 5 As shown, the embodiment of the utility model provides an implementation method, a support rod 18 is provided at the axis of the plug connector 9, one end of the support rod 18 is connected to a fixing rod 19, and the other end of the support rod 18 is provided with an elastic closing plate 20. The elastic closing plate 20 is a circular plate made of rubber material, which is connected and fixed by the support rod 18 so that the elastic closing plate 20 cannot move up and down, but when subjected to pressure, the elastic closing plate 20 will deflect up and down, thereby opening up the inside of the plug connector 9.

[0043] like Figure 2 As shown, when the embodiment of the utility model is in specific operation, the device is transported to the place where air needs to be collected, and the height of the device is placed as required.

[0044] The telescopic end of the electric telescopic push rod 11 is controlled in advance to extend and push the push plate 12 to rise, so that the liquid in the liquid filling storage bag 6 enters the gas collection adsorption bag 7 through the ring 8 and the plug connector 9, and the air in the gas collection adsorption bag 7 is driven out from the plug connector 9 on the upper side of the gas collection adsorption bag 7 until the liquid fills the gas collection adsorption bag 7.

[0045] Afterwards, the telescopic end of the electric telescopic push rod 11 is controlled to drive the push plate 12 to descend. Under the action of gravity, the liquid in the gas collection adsorption bag 7 enters the liquid filling and storage bag 6 through the plug connector 9; at the same time, a negative pressure state is formed in the gas collection adsorption bag 7, and the external air enters the gas collection adsorption bag 7 through the upper plug connector 9. In order to prevent the liquid in the gas collection adsorption bag 7 from flowing down and causing the gas collection adsorption bag 7 to shrink and flatten, the gas collection adsorption bag 7 can be set to a hard material (such as hard plastic), and the liquid filling and storage bag 6 can be set to a soft material (such as a soft film-like plastic material). The external air is supplemented into the gas collection adsorption bag 7 through the upper plug connector 9, thereby collecting the air in the gas collection adsorption bag 7.

[0046] After collection, the gas collection adsorption bag 7 can be taken out by opening the opening and closing door 3 and separating the plug connectors 9 at both ends. Labels can be made on the surface of the gas collection adsorption bag 7 for easy subsequent inquiry. In addition, when air or liquid flows through the plug connector 9, the edge of the elastic sealing plate 20 is bent under the pressure of air pressure or hydraulic pressure, so that the air or liquid flows through the gap between the inner wall of the plug connector 9 and the bent part of the elastic sealing plate 20.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
