Description

Technical Field

[0001] This utility model relates to the field of purge bottle technology, specifically a portable foldable purge bottle. Background Technology

[0002] In the field of gas analysis, purge bottles are indispensable equipment for both routine laboratory testing and on-site industrial analysis. They use high-pressure gas to clean sampling instruments and analytical equipment, ensuring the accuracy and reliability of test data.

[0003] Based on the above, the inventors have discovered the following problems: the existing purge bottles are large in size and extremely inconvenient to carry. In actual use, they cause many problems for researchers and testing engineers, and seriously restrict the efficiency and flexibility of gas analysis work.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide a portable, foldable blow bottle, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a portable, foldable purge bottle to solve the problem mentioned in the background art that existing purge bottles are large in size and extremely inconvenient to carry.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A portable, foldable purge bottle includes a purge bottle body, a sealing mechanism, and a protective mechanism. The bottle wall of the purge bottle body has a corrugated, expandable structure. The protective mechanism includes a bottom shell and a top shell, both of which are fitted onto the outside of the purge bottle body. The bottom end of the purge bottle body is fixedly connected to the inner bottom end of the bottom shell, and the outer upper end of the purge bottle body is connected to the inner upper end of the top shell. The bottom shell and the top shell are slidably connected. The sealing mechanism includes a bottle head, the outer edge of the bottom end of which is fixedly connected to the outer edge of the top end of the purge bottle body. Both the purge bottle body and the bottle head are made of soluble polytetrafluoroethylene (PTFE). Furthermore, a frustum-shaped clamp is fitted onto the upper end of the bottom shell, and the frustum-shaped clamp has several grooves.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the frustum-shaped clamp and groove design at the upper end of the bottom shell, when engaged with the locking sleeve, can clamp and fix the outer wall of the top shell after being squeezed, thereby fixing the moving position of the top shell.

[0009] Furthermore, a locking sleeve is threadedly connected to the upper outer side of the bottom shell, and the upper inner end of the locking sleeve is provided with an inclined groove adapted to the outer side of the frustum-shaped clamp.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the locking sleeve on the outer side of the upper end of the bottom shell cooperates with the frustum-shaped clamp and is connected by threads. The position of the frustum-shaped clamp can be adjusted. After the top shell and bottom shell slide relative to each other to adjust the extension and retraction state of the purge bottle body, the locking sleeve is used to fix the frustum-shaped clamp, thereby locking the relative position of the top shell and bottom shell.

[0011] Furthermore, the inner wall of the inclined groove abuts against the outer wall of the frustum-shaped clamp.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the inner wall of the inclined groove and the outer wall of the frustum-shaped clamp are in close contact. As the locking sleeve of the threaded connection moves, the inclined groove inside it squeezes the frustum-shaped clamp, which improves the locking effect of the frustum-shaped clamp on the top shell, ensures the stability when fixing the relative position of the top shell and the bottom shell, and prevents accidental slippage.

[0013] Furthermore, a convex coil is provided on the outer side of the bottom end of the bottle head, and a concave coil is provided on the outer side of the upper end of the bottle head.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the convex coil at the bottom of the bottle head and the concave coil at the top allow the bottle head to extend to the convex coil and the concave coil for folding and telescoping, thereby retracting the bottle head into the interior of the blow bottle body, thereby further reducing the space occupied. When in use, the bottle head can be pulled out.

[0015] Furthermore, the upper end of the bottle head is threaded with a bottle cap, and the outer side of the bottle cap has several anti-slip textures.

[0016] The beneficial effects of adopting the above-mentioned further solution are that the threaded cap at the upper end of the bottle head prevents leakage of the contents of the bottle, and the anti-slip texture on the outside of the cap makes it easy for users to unscrew or tighten the cap, improving operational convenience. Furthermore, an anti-slip pad, made of silicone material, is fixedly installed at the bottom end of the base shell.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the silicone anti-slip pad at the bottom of the bottom shell increases the friction between the blow bottle and the placement surface, preventing the blow bottle from sliding during placement and improving placement stability. Compared with the prior art, the beneficial effects of this utility model are: the portable foldable blow bottle, with the blow bottle body and bottle head made of soluble polytetrafluoroethylene material, has good chemical stability and corrosion resistance. The corrugated telescopic structure of the blow bottle body facilitates folding after use, reducing storage space and making it easy to carry. The bottom shell and top shell of the protective mechanism are fitted onto the outside of the blow bottle body, providing protection. The bottom shell and top shell are slidably connected, and together with the telescopic structure of the blow bottle body, they facilitate storage and protect the blow bottle body. The sealing mechanism's bottle head and top of the blow bottle body... The end is fixedly connected to achieve a seal on the blow bottle body. The locking sleeve on the outer side of the upper end of the bottom shell cooperates with the frustum-shaped clamp. The position of the frustum-shaped clamp can be adjusted through the threaded connection. After the top shell and bottom shell slide relative to each other to adjust the extension state of the blow bottle body, the locking sleeve is used to fix the frustum-shaped clamp, thereby locking the relative position of the top shell and bottom shell. The convex coil at the bottom end of the bottle head and the concave coil at the top end allow the bottle head to extend to the convex coil and concave coil for folding and extension, thereby retracting the bottle head into the interior of the blow bottle body, thereby further reducing the space occupied. When in use, the bottle head can be pulled out. Attached Figure Description

[0024] Please see Figure 1 - Figure 5This utility model provides a technical solution: a portable foldable blow bottle, including a blow bottle body 100, a sealing mechanism 101, and a protective mechanism 102. The bottle wall of the blow bottle body 100 has a corrugated and retractable structure. The protective mechanism 102 includes a bottom shell 10201 and a top shell 10203, both of which are sleeved on the outside of the blow bottle body 100. The bottom end of the blow bottle body 100 is fixedly connected to the inner bottom end of the bottom shell 10201, and the outer upper end of the blow bottle body 100 is connected to the inner upper end of the top shell 10203. The bottom shell 10201 and the top shell 10203 are slidably connected. The sealing mechanism 101 includes a bottle head 10101, the outer edge of the bottom end of the bottle head 10101 is fixedly connected to the outer edge of the top end of the blow bottle body 100. Both the purge bottle body 100 and the bottle head 10101 are made of soluble polytetrafluoroethylene (PTFE). The purge bottle body 100 and the bottle head 10101 are made of soluble PTFE, which has good chemical stability and corrosion resistance. The corrugated and retractable structure of the purge bottle body 100 makes it easy to fold after use, reducing storage space and making it easy to carry. The bottom shell 10201 and the top shell 10203 of the protective mechanism 102 are fitted on the outside of the purge bottle body 100 to protect it. The bottom shell 10201 and the top shell 10203 are slidably connected and, together with the retractable structure of the purge bottle body 100, make it easy to store and protect the purge bottle body 100. The bottle head 10101 of the sealing mechanism 101 is fixedly connected to the top of the purge bottle body 100 to seal the purge bottle body 100. The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 5A frustum-shaped clamp 10204 is fitted onto the upper end of the bottom shell 10201. The frustum-shaped clamp 10204 has several grooves 10205. A locking sleeve 10202 is threaded onto the outer side of the upper end of the bottom shell 10201. The upper end of the locking sleeve 10202 has an inclined groove 10206 adapted to the outer side of the frustum-shaped clamp 10204. The inner wall of the inclined groove 10206 abuts against the outer wall of the frustum-shaped clamp 10204. The design of the frustum-shaped clamp 10204 and grooves 10205 at the upper end of the bottom shell 10201 allows the frustum-shaped clamp 10204 to clamp and fix the outer wall of the top shell 10203 when it is compressed by the locking sleeve 10202, thereby fixing the movement position of the top shell 10203. The locking sleeve 10204 on the outer side of the upper end of the bottom shell 10201... 202 engages with the frustum-shaped clamp 10204 via a threaded connection, allowing adjustment of the position of the frustum-shaped clamp 10204. After the top shell 10203 and bottom shell 10201 slide relative to each other to adjust the telescopic state of the purge bottle body 100, the locking sleeve 10202 fixes the frustum-shaped clamp 10204, thereby locking the relative position of the top shell 10203 and bottom shell 10201. The inner wall of the inclined groove 10206 tightly abuts against the outer wall of the frustum-shaped clamp 10204. As the threaded locking sleeve 10202 moves, its internal inclined groove 10206 presses against the frustum-shaped clamp 10204, improving the locking effect of the frustum-shaped clamp 10204 on the top shell 10203, ensuring stability when fixing the relative position of the top shell 10203 and bottom shell 10201, and preventing accidental slippage.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 5The bottle head 10101 has a convex coil 10104 on the outer side of its bottom end and a concave coil 10103 on the outer side of its upper end. A bottle cap 10102 is threaded onto the upper end of the bottle head 10101. Several anti-slip textures are provided on the outer side of the bottle cap 10102. An anti-slip pad made of silicone is fixedly installed at the bottom of the bottom shell 10201. The convex coil 10104 at the bottom and the concave coil 10103 at the top of the bottle head 10101 allow the bottle head 10101 to extend to the convex coil 10104 and the concave coil 10103 for folding. The telescopic mechanism retracts the bottle head 10101 into the body of the blow bottle 100, further reducing its space requirements. When in use, the bottle head 10101 can be pulled out. The bottle cap 10102, threaded onto the upper end of the bottle head 10101, prevents leakage of the contents. The anti-slip texture on the outer side of the bottle cap 10102 facilitates unscrewing or tightening, improving ease of operation. The silicone anti-slip pad at the bottom of the base 10201 increases the friction between the blow bottle and the placement surface, preventing the blow bottle from sliding during placement and improving stability. Specifically, the working principle of this portable foldable blow bottle is as follows: During daily carrying and use of the blow bottle, the blow bottle body 100, with its corrugated telescopic structure and the soluble polytetrafluoroethylene material used together with the bottle head 10101, exhibits good practicality and durability. When it is necessary to store the blow bottle, the bottle head 10101 can first be retracted into the blow bottle body 100 along the convex coil 10104 and the concave coil 10103 to further reduce space occupation. Then, by sliding the top shell 10203, the corrugated structure of the blow bottle body 100 is compressed to realize the folding of the blow bottle body 100. After adjusting the telescopic state of the blow bottle body 100, the locking sleeve 10202 on the outer side of the upper end of the bottom shell 10201 is rotated. Because the locking sleeve 10202 is threadedly connected to the bottom shell 10201, and its internal inclined groove 10206 tightly abuts against the outer wall of the frustum-shaped clamp 10204, as the locking sleeve 10202 moves, the inclined groove 10206 will squeeze the frustum-shaped clamp 10204, causing it to clamp and fix the outer wall of the top shell 10203, thereby locking the relative position of the top shell 10203 and the bottom shell 10201 and preventing the purge bottle body 100 from accidentally unfolding. When the purge bottle needs to be used, the locking sleeve 10202 is rotated in the opposite direction to release the frustum-shaped clamp. The clamp 10204 holds the top shell 10203, slide the top shell 10203 to unfold the purge bottle body 100, and then pull the bottle head 10101 out of the purge bottle body 100. After use, screw on the bottle cap 10102. Its threaded connection with the bottle head 10101 can prevent the contents of the bottle from leaking. The anti-slip texture on the outside of the bottle cap 10102 makes it easy for the user to operate. When placing the purge bottle, the silicone anti-slip pad at the bottom of the bottom shell 10201 increases the friction with the placement surface to prevent the purge bottle from sliding and ensure stable placement.
