Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-2, a plant volatile gas collection bag comprises a bag body 10 with an opening, wherein a self-sealing strip 110 is arranged at the opening of the bag body, a regulating valve capable of being communicated with the inside of the bag body is arranged at the middle part of the bag body, the regulating valve comprises a valve seat 210 and a valve body 220 which is connected with the valve seat 210 through threads and used for being communicated with the outside of the valve seat 210, a communicating inner cavity 211 communicated with the inner cavity of the bag body is arranged inside the valve seat 210, an air suction pipe 221 is communicated with the hollow inside of the valve body and the side part of the valve body, the air suction pipe is connected with an air suction pump through a pipeline, and.

The self-sealing strip 110 of the bag mouth of the bag body is the existing self-sealing bag, namely, grooves which can be used for sealing the bag mouth and are matched with each other are arranged on the two sides of the bag mouth to realize sealing.

The sealing mechanism comprises a plug screw 30 in threaded connection with the upper part of the valve body 220, an annular flange 310 extends from the surface of the plug screw facing the inner cavity of the valve body, a cylindrical rubber plug 40 capable of blocking an opening at the upper part of the communicating inner cavity 211 is fixed in the annular flange, and the upper end surface of the plug screw is further provided with an injection hole 320 for the needle of the syringe to pass through.

The screw plug is provided with an injection hole 320 which is convenient for the syringe needle to pass through, the compression degree of the upper end opening of the communicating inner cavity 211 of the columnar rubber plug 40 can be adjusted through the rotation of the screw plug 30 in the using process, and then the opening and closing of the communicating inner cavity 211 are controlled.

In the second embodiment, the bottom of the valve seat 210 has a flange extending outward, a sealing ring 212 is disposed between the lower end of the valve body and the flange, and the bottom of the valve body 220 has a sealing groove 222 into which the sealing ring is inserted.

In the above-mentioned embodiment, in order to realize the fixed of governing valve and the bag body, bag body lateral part has the through-hole, and disk seat and the bag body adopt plastic construction, and disk seat bottom periphery passes through hot-pressing welded connection with the through-hole edge of the bag body, perhaps can make the disk seat be located the bag internally, and the through-hole is passed to the upper end of disk seat, presss from both sides the bag body between disk seat and valve body, fixed back intercommunication inner chamber 211 can guarantee with the inside UNICOM of the bag body.

In this embodiment, first, the whole plant or plant tissue (leaves, flowers, fruits, etc.) is placed in the bag, the groove of the self-sealing strip at the bag opening is fastened with the convex rib, and the bag is sealed. Then, the screw plug 30 is unscrewed to enable the cylindrical rubber plug 40 to be separated from the sealing of the upper end opening of the communicating inner cavity 211, the air in the bag body is rapidly pumped away by the air pump from the air pumping pipe 221 on the valve, and then the screw plug 30 is screwed down. The cylindrical rubber plug 40 is guaranteed to plug the upper end opening of the communicating inner cavity 211, and fresh air with required quantitative volume is injected into the bag body by using auxiliary tools such as a syringe and the like according to needs. Place the volatile gas that a period of time made the plant tissue release and enrich in the bag body, because cylindricality rubber buffer 40 rubber materials can realize the shutoff under the effect of self elasticity after the syringe needle is extracted and guarantee sealedly, finally, rock and gather the purpose that the bag reaches the internal gas of mixing cup to again will insert the syringe needle and penetrate and pass cylindricality rubber buffer 40 from injection hole 320, extract the gas of required volume and detect.
