Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in figure 1, figure 2 and figure 3, the utility model discloses a gas liquid sampler and sampling bottle, including the sampling bottle 1 of being made by the processing of polytetrafluoroethylene material, the thickness of sampling bottle 1 is 0.8mm-1.2 mm. The sampling bottle 1 is a telescopic corrugated structure, and the number of corrugations can be adjusted according to actual needs. The top of the sampling bottle 1 forms a positioning shoulder 1a and the bottom of the sampling bottle 1 forms a push-pull limiting groove 1 b.

The top of the sampling bottle 1 close to the positioning shoulder 1a is sunken into the storage cavity 1c to form a flow guide part 11, a flow guide hole 11a for inserting the sampling guide pipe 3 is formed in the flow guide part 11, the flow guide hole 11a is coaxial with the sampling bottle 1, and a port of the flow guide hole 11a close to a limiting groove of the sampling bottle 1 is hermetically connected with a piercing flow guide film; the flow guide part 11 is close to an end part circulation hole 11b of a limiting groove of the sampling bottle 1, and the flow guide hole 11a is communicated with the storage cavity 1c through the circulation hole 11 b; a gap is reserved between the storage cavities 1c of the flow guide part 11, the gap surrounds the flow guide part 11 for a circle, an elastic latex tube film 62 is fixedly sleeved on the outer surface of the flow guide part 11, and the elastic latex tube film 62 covers and seals the circulation hole 11b through self elasticity. Normally, the elastic latex tube film 62 closes the flow through hole 11 b. However, when an external force is applied, the elastic latex tube film 62 can be expanded to open the flow hole 11b and communicate with the storage chamber 1 c.

The sampler comprises a sampling pipe 3, a sampling main body 4 and a push-pull handle 5 which are sequentially arranged, wherein the sampling pipe 3 is detachably and fixedly connected with the sampling main body 4; an open accommodating cavity 4c is formed in the sampling main body 4, the accommodating cavity 4c can be used for placing the sampling bottle 1, a fixing groove 41 matched with the positioning shoulder 1a is formed on one side, close to the sampling guide pipe 3, of the accommodating cavity 4c, and the fixing groove 41 can be used for the positioning shoulder 1a to be embedded in and clamped and connected with the positioning shoulder 1 a; the push-pull handle 5 is connected with the sampling main body 4 in a sliding mode, the connecting end of the push-pull handle 5 is located in the containing cavity 4c, a push-pull groove 42 is formed in the connecting end, the push-pull groove 42 can be used for being embedded into the push-pull limiting groove 1b, and the connecting end of the push-pull handle 5 is connected with the push-pull limiting groove 1b in a clamping mode. The sampling body 4 is provided with an index finger hole 4a for the insertion of an index finger and a middle finger hole 4b for the insertion of a middle finger.

The unused sample vial 1 is in a compressed state, i.e., the sample vial 1 is in a state of shortest length and smallest internal volume. In use, an unused sample vial 1 is placed in the receiving cavity 4c of the sample body 4 of the sampler. The fixing groove 41 can be used for embedding the positioning shoulder 1a and is connected with the positioning shoulder 1a in a clamping manner, and the push-pull groove 42 can be used for embedding the push-pull limiting groove 1b and realizing the clamping connection of the connecting end of the push-pull handle 5 and the push-pull limiting groove 1b, so that the sampling bottle 1 can be well fixed in the accommodating cavity 4c of the sampling main body 4. The sampling tube 3 is inserted into the guide hole 11a of the guide portion 11 of the sampling bottle 1. The index finger and the middle finger of the right hand of the operator respectively penetrate into the index finger hole 4a and the middle finger hole 4b on the sampling body 4, and the sampling operation is completed through the thumb of the right hand or the left-right auxiliary operation.

When sampling, the sampling pipe 3 is placed at a reasonable sampling position. The push-pull handle 5 is pulled outwards, the volume of the storage cavity 1c of the sampling bottle 1 is increased, the pressure is reduced, and a negative pressure state is formed. The internal and external pressure difference makes the elastic latex tube film 62 sleeved on the flow guide part 11 inside the sampling bottle 1 deform and expand, so that the sampling conduit 3 is communicated with the storage cavity 1c through the flow guide hole 11a and the flow through hole 11b to form a flow guide passage of gas or liquid to enter the sampling bottle 1. When the push-pull handle 5 is stopped being pulled, the volume of the storage cavity 1c does not change, and the pressure difference between the inner side and the outer side of the elastic latex tube film 62 disappears. The elastic latex tube film 62 is re-coated on the guide 11 and blocks the flow hole 11 b. The flow guide passage for gas or liquid to enter the storage cavity 1c is blocked, so that the inside of the sampling bottle 1 is sealed and isolated from the outside.

Even if the push-pull handle 5 is pushed in the opposite direction at this time, although the volume of the storage chamber 1c tends to decrease, the conductance path still cannot be formed due to the elastic force of the elastic latex tube film 62 itself.

In order to backflow the sample of the sampler cell phone, follow-up work is carried out. Can go down sampling tube 3, then insert sampling tube 3 in the water conservancy diversion portion 11 by water conservancy diversion hole 11a backward to sampling tube 3 punctures and pierces the water conservancy diversion membrane, forms the water conservancy diversion route that storage cavity 1c and sampling tube 3 inside sampling bottle 1 directly communicate from this, promotes the push-and-pull hand (hold) this moment, can go out the sample in sampling bottle 1 through sampling tube 3 water conservancy diversion, carries out operation or experiment etc. next step.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
