Detailed Description
In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.
Referring to fig. 1, a liquid self-sealing sampling bottle comprises a bottle body 1 and a bottle cap 2, wherein the bottle cap 2 is a hollow chamber, the lower chamber wall of the chamber is hermetically connected with a bottle mouth, and a gas outlet 3 is arranged on the chamber side wall of the chamber and is connected with an adsorption device 4 through a conduit; the cavity in be provided with cavity sealing rod 6, cavity sealing rod 6 upper and lower extreme all stretch out outside the cavity, stretch out and be provided with inlet 7 on the cavity outer cavity sealing rod upper end roof, stretch out and be provided with liquid outlet 8 on the cavity outer cavity sealing rod lower extreme pole wall, along a plurality of ventholes 9 of cavity sealing rod circumference equipartition on the lower chamber wall, preferably, the venthole is 2-5, stretches out the cavity outer cavity sealing rod lower extreme tip and links to each other with sealed the pad 10, sealed pad 10 and venthole 9 position correspond the realization feed liquor hole sealed, the sealing rod upper portion that is located the cavity is provided with spacing platform 11, last spacing platform and lower chamber wall between be provided with spring 12.
Preferably, the bottom of the bottle body is sleeved with an anti-scald sleeve (not shown in the attached drawings).
Preferably, the sealing gasket is made of rubber materials or polyurethane materials.
When sampling, the sampling needle is inserted into the liquid inlet, the collected liquid enters the hollow sealing rod 6, under the action of the gravity of the collected liquid, the hollow sealing rod 6 moves downwards, the liquid outlet 8 moves downwards into the bottle body, the collected liquid flows out of the liquid outlet 8 and enters the bottle body, meanwhile, the sealing gasket 10 leaves the lower cavity wall of the cavity, the sealing of the air outlet 9 is automatically released, the gas volatilized by the sampled liquid enters the cavity from the air outlet, is discharged from the air outlet and is absorbed by the absorption device, the sampling is realized, after sampling is finished, the action of the weight of the collected liquid disappears, as shown in figure 2, the compression spring is reset, the hollow sealing rod 6 is reset upwards, the sealing gasket 10 is propped against the lower cavity wall of the cavity, and then realize the sealed of venthole 9 on the cavity wall under the cavity to realize the self sealss, zero leakage has ensured the injury of medium to the staff in the sampling process.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
