Description
Technical Field
[0001] The utility model belongs to the technical field of environmental detection equipment, and particularly relates to a porous glass plate absorption bottle. Background Art
[0002] Porous glass plate absorption bottles are usually used as reaction vessels in the process of gas component detection and analysis. They are mainly used to collect gaseous and vapor substances. They can also collect mist aerosols and various samples in the air, such as sulfur dioxide (HJ 482-2009), nitrogen oxides (HJ 479-2009), ozone (HJ 504-2009), etc.
[0003] At present, in the process of adding absorption liquid to the porous glass plate absorption bottle, a pipette is usually used in conjunction with an ear bulb or other blowing device for injection. However, due to the negative pressure in the porous glass plate absorption bottle, the process of adding absorption liquid is extremely difficult. If you are not careful or the injection speed is too fast, the absorption liquid will overflow, resulting in the inability to accurately quantify the absorption liquid, affecting the accuracy of the test results; at the same time, due to the small inlet and outlet diameters of the porous glass plate absorption bottle, the absorption liquid often adheres to the inner wall of the liquid adding tube, resulting in residual absorption liquid at the tube mouth, and there is a risk of being sucked into the sampler later, resulting in distorted test results; in addition, in order to avoid overflow of the absorption liquid, it is necessary to control the injection speed, resulting in very slow and time-consuming liquid addition, which seriously affects the efficiency of sample detection.
[0004] Therefore, it is necessary to design a porous glass plate absorption bottle that can effectively avoid the phenomenon of absorption liquid overflowing and remaining during the liquid injection process. Summary of the invention
[0005] In order to solve the above technical problems, the utility model proposes a porous glass plate absorption bottle, which can effectively avoid the outflow and overflow of the absorption liquid during the liquid injection process and the residue of the absorption liquid at the liquid adding tube mouth, ensure the accurate quantification of the absorption liquid, thereby ensuring the accuracy of the detection and analysis results, and the liquid adding speed is fast, the liquid adding and detection efficiency are improved, and the operation is simple, convenient, time-saving and labor-saving.

[0020] Compared with the prior art, the utility model has the following advantages and effects:
[0021] (1) An anti-overflow block is movably arranged on the inner wall of the branch transverse folded tube. The anti-overflow block is adapted to the inner diameter of the branch transverse folded tube to form a seal on the tube opening of the branch transverse folded tube, which can effectively prevent the overflow of the absorption liquid during the injection process, improve the injection speed and injection efficiency, and ensure the accurate quantification of the absorption liquid, thereby ensuring the accuracy of the detection and analysis results;
[0022] (2) An anti-overflow block including a column part and a cone part is used, and the length of the cone part is not greater than the diameter of the branch transverse fold tube, so that after the liquid is added, the anti-overflow block can be slowly pushed to the bend, and a small amount of absorption liquid adhering to the inner wall is gathered and accumulated under the pushing action of the cone part, and automatically falls into the branch tube under the action of its own gravity, thereby eliminating the absorption liquid residue at the outlet of the branch transverse fold tube and preventing it from being sucked into the sampler during subsequent use;

DETAILED DESCRIPTION
[0035] In order to enable those skilled in the art to better understand the present invention, the present invention is now further described in conjunction with specific implementation methods.
[0036] Embodiment 1:
[0037] like Figure 1~Figure 4 As shown, the utility model provides a porous glass plate absorption bottle, which includes a U-shaped absorption tube consisting of a main tube 1 and a branch tube 2. The main tube 1 is provided with a spherical transition tube 11 near the top thereof, and a porous glass plate 12 is provided near the bottom thereof. The end of the main tube 1 is provided with a main transverse folded tube 13, and the end of the branch tube 2 is provided with a branch transverse folded tube 21. It should be noted that the U-shaped porous glass plate absorption tube is an existing mature technology, and its specific structure and size are not repeated here.
[0038] like Figure 1 and Figure 2 As shown, the porous glass plate absorption bottle in this embodiment also includes an anti-overflow blocking block 3 movably arranged on the inner wall of the supporting transverse folded tube 21, and the anti-overflow blocking block 3 is adapted to the inner diameter of the supporting transverse folded tube 21, so that the anti-overflow blocking block 3 and the inner wall of the supporting transverse folded tube 21 are sealed and abutted, thereby preventing the absorption liquid from flowing out from between the inner wall of the supporting transverse folded tube 21 and the anti-overflow blocking block 3 during the liquid addition process; Figure 2 and Figure 3 As shown, the anti-overflow block 3 includes a column portion 31 and a cone portion 32, and the column portion 31 and the cone portion 32 are an integrated structure, wherein the column portion 31 and the cone portion 32 are both silicone blocks to avoid contamination of the sample during the sampling process; optionally, in some embodiments, the distal ends of the column portion 31 and the cone portion 32 are provided with chamfered corners.
[0039] The length of the cone portion 32 is not greater than the inner diameter of the cross-bend tube 21. Figure 3 , Figure 4As shown, the length of the cone portion 32 is smaller than the inner diameter of the branch transverse folded tube 21, so that when the anti-overflow blocking block 3 is pushed toward the bend, a small amount of absorption liquid adhering to the inner wall of the branch transverse folded tube 21 accumulates on the side wall of the cone portion 32, and finally the cone portion 32 extends into the bend, while the column portion 31 moves to the end of the horizontal pipe section of the branch transverse folded tube 21, and the accumulated absorption liquid automatically falls into the branch tube 2 below under the action of gravity, thereby ensuring sufficient filling of the absorption liquid while avoiding the absorption liquid remaining at the tube mouth of the branch transverse folded tube 21, thereby ensuring the accuracy of the detection and analysis results.
[0040] The anti-overflow block 3 is provided with an injection channel 33, which passes through the axis of the column part 31 and the cone part 32. The injection channel 33 gradually narrows from the column part 31 to the cone part 32. The injection channel 33 is adapted to the diameter of the pipette head (gun head) of the pipette. During the injection process, the anti-overflow block 3 is first embedded and installed at the end of the branch transverse fold tube 21, and then the pipette head is inserted along the injection channel 33 for injection. In order to ensure that the absorption liquid is completely injected into the absorption tube and the injection speed, the pipette head is preferably passed through the injection channel 33 and extended into the inside of the branch transverse fold tube 21. It should be noted that in order to reduce the difficulty of operation, the anti-overflow block 3 can be first set on the pipette head of the pipette, and then the whole can be inserted into the end of the branch transverse fold tube 21.
[0041] like Figure 3 , Figure 4 As shown, a pull rope 4 is provided at the end of the column base portion 31 of the anti-overflow block 3, and two pull ropes 4 are provided, and the two pull ropes 4 are symmetrically arranged. The length of the pull rope 4 is greater than the length of the supporting transverse fold tube 21, so that when the anti-overflow block 3 is pushed to the bending part of the supporting transverse fold tube 21, part of the pull rope 4 is still located outside the pipe mouth of the supporting transverse fold tube 21, thereby facilitating the anti-overflow block 3 to be pulled out of the supporting transverse fold tube 21 for subsequent detection steps.
[0042] Optionally, in some embodiments, the pull rope 4 is detachably connected to the anti-overflow block 3, and the pull rope 4 can be removed as needed for easy storage. The specific connection structure can adopt a hook or a clamping ring structure, and the detailed structure will not be described one by one.
[0043] It should be noted that, in most existing porous glass plate absorption bottles, the main transverse folded tube 13 and the branch transverse folded tube 21 have the same diameter. The anti-overflow block 3 in this embodiment can be set at the end pipe mouth of the main transverse folded tube 13 or the branch transverse folded tube 21 according to specific needs. This embodiment does not limit the injection of absorption liquid through the main transverse folded tube 13 or the branch transverse folded tube 21 during the injection process, and the anti-overflow block 3 can be set according to the injection pipe section.
[0044] Embodiment 2:
[0045] For Example 2 of the utility model, Figure 5~Figure 7Note that description of parts that are not different from those in Embodiment 1 will be omitted and will be given the same reference numerals.
[0046] like Figure 5~Figure 7 As shown, the porous glass plate absorption bottle involved in the utility model also includes a sealing rubber cap 5, which is specifically a silicone cap. Both ends of the sealing rubber cap 5 are provided with chamfered corners. The sealing rubber cap 5 is detachably mounted on the outer periphery of the supporting transverse folded tube 21. The sealing rubber cap 5 is provided with a sealing groove 52 adapted to the tube wall of the supporting transverse folded tube 21 to seal the tube mouth end of the supporting transverse folded tube 21.
[0047] like Figure 6 As shown, a receiving platform 51 is provided inside the sealing rubber cap 5, and the sealing groove 52 is surrounded by the inner wall of the sealing rubber cap 5 and the outer wall of the receiving platform 51. The receiving platform 51 is provided with a placement groove 511 adapted to the frustum portion 32, so as to place the anti-overflow blocking block 3 in the sealing rubber cap 5. A positioning column 512 adapted to the injection channel 33 is also provided at the bottom of the receiving platform 51. The frustum portion 32 of the anti-overflow blocking block 3 can be placed downward in the placement groove 511, and the positioning column 512 is inserted in the injection channel 33, which can improve the placement stability of the anti-overflow blocking block 3 and the sealing rubber cap 5. For details, refer to Figure 7 shown.
[0048] Optionally, in some embodiments, a connecting hook or a clamping ring structure is provided at the bottom end of the sealing rubber cap 5 so that it can be detachably connected to the end of the pull rope 4, and the anti-overflow block 3 can be used and placed together with the sealing rubber cap 5 to improve the convenience of use.
[0049] Embodiment 3:
[0050] For Example 3 of the utility model, Figure 8 Note that description of parts that are not different from those in Embodiment 1 will be omitted and will be given the same reference numerals.
[0051] like Figure 8 As shown, the utility model relates to a porous glass plate absorption bottle, in which the generatrix of the frustum portion 32 of the anti-overflow blocking block 3 is in an inwardly concave arc shape, so that the cone bottom end of the frustum portion 32 has a larger contact area relative to the cone top end, so that when the anti-overflow blocking block 3 is pushed, a small amount of absorption liquid adhering to the supporting cross-fold tube 21 is more likely to gather at the cone bottom position of the frustum portion 32, thereby avoiding its gathering at the cone top position to cause part of the absorption liquid to flow into the injection channel 33; at the same time, the inwardly concave arc-shaped side wall surface is more likely to promote the dripping of the absorption liquid, thereby avoiding the absorption liquid adhering to the side wall of the frustum portion 32 and causing the loss of the absorption liquid.
[0052] In summary, the porous glass plate absorption bottle provided by the utility model can effectively avoid the outflow and overflow of the absorption liquid during the liquid filling process and the residual absorption liquid at the liquid filling tube mouth, ensure the accurate quantification of the absorption liquid, thereby ensuring the accuracy of the detection and analysis results, and the liquid filling speed is fast, the liquid filling and detection efficiency are improved, and the operation is simple, convenient, time-saving and labor-saving.
[0053] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should still fall within the scope of the present invention.
