Technical Field
[0001] This utility model relates to the field of absorption bottle technology, specifically to an intelligent absorption bottle for liquid absorption methods that prevents backflow and evaporation. Background Technology
[0002] A liquid absorption bottle is a laboratory glass (or plastic) vessel used to collect and enrich gaseous pollutants. Its core principle is to pass the target gas as bubbles through a specific absorbent liquid inside the bottle, transferring the target component from the gas phase to the liquid phase through dissolution or chemical reaction. It is typically equipped with an inlet and outlet tube to ensure uniform gas dispersion and sufficient contact with the liquid. The main functions of a liquid absorption bottle are threefold: first, sampling and enrichment, which efficiently captures low-concentration gases and concentrates the analyte from a large amount of gas into a small amount of liquid, greatly improving detection sensitivity; second, pretreatment and separation, by selecting a specific absorbent liquid, the target substance can be selectively absorbed, thereby eliminating interference from other components in the gas; and third, sample preservation and transformation, as the absorbent liquid can stabilize the captured substance or transform gaseous components into more easily analyzed stable compounds. Therefore, liquid absorption bottles are indispensable gas sample pretreatment tools in fields such as environmental monitoring, industrial hygiene, and chemical analysis.
[0003] Existing absorption bottles make it difficult to adjust the flow rate and velocity of the liquid in the tubing when delivering liquids. This results in long sampling times for low-concentration samples to obtain a detectable amount, leading to solvent evaporation, changes in concentration, and reduced detection efficiency. Improvements are needed.
[0004] In view of this, we propose a smart absorption bottle for liquid absorption methods that prevents backflow and evaporation. Utility Model Content
[0005] The purpose of this invention is to provide an intelligent absorption bottle for liquid absorption methods that prevents backflow and evaporation. This intelligent absorption bottle solves the problem that it is difficult to adjust the flow rate and velocity of the liquid in the tubing, which leads to long sampling times for low-concentration samples to obtain a detectable amount, resulting in solvent evaporation, changes in concentration, and reduced detection efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A smart absorption bottle for liquid absorption with anti-backflow and anti-evaporation features includes an absorption bottle mechanism. The absorption bottle mechanism includes a bottle body with a cap threaded to the top. A long tube and a short tube are fixedly inserted through the top of the cap. It also includes a flow regulating mechanism for regulating the flow rate inside the long tube, and a limiting mechanism for limiting the flow regulating mechanism. The flow regulating mechanism includes a rotating rod, one end of which passes through and is rotatably connected to the long tube, and the other end of which, away from the long tube, passes through and is fixedly connected to a wheel.
[0008] Preferably, the flow regulating mechanism further includes a sphere, the inner wall of the long tube has a groove for covering the sphere, the outer surface of the sphere has a through hole for conveying liquid, and a rotating block is fixedly connected to the end of the rotating rod away from the long tube.
[0009] Preferably, the end of the rotating rod away from the rotating block is fixedly connected to the circumferential surface of the sphere, and the rotating block can drive the sphere to rotate through the rotating rod when rotating, and the sphere is located inside the long tube.
[0010] Preferably, the limiting mechanism includes a short rod A, one end of which is fixedly connected to the circumferential surface of the long tube, and a claw is rotatably connected to the end of the short rod A away from the long tube. A short rod B is fixedly connected to the outer surface of the long tube, and a spring is fixedly connected to the end of the short rod B away from the long tube. The end of the spring away from the short rod B is fixedly connected to the bottom of the claw.
[0011] Preferably, the inclined surface of the thorn teeth on the thorn wheel is in contact with the thorn claw. When the thorn wheel rotates, it can push the thorn claw to rotate around the short rod A as the origin through the thorn teeth. The thorn wheel and the thorn claw mesh with each other. When the thorn wheel rotates clockwise, it will be limited by the thorn claw.
[0012] Preferably, the short rod B is located below the short rod A, the thorn wheel is located between the rotating block and the long tube, and the thorn claw can be reset by the spring on the short rod B during movement.
[0013] Preferably, the outer surface of the sphere is in contact with the inner wall of the groove, the inner wall of the long tube is located on the displacement trajectory of the through hole, and the contact area between the through hole and the inner wall of the long tube can be changed when the sphere rotates.
[0014] Preferably, the bottle body is made of glass and the bottle cap is made of high-density polyethylene.
[0015] Preferably, the inner wall of the groove is located on the displacement trajectory of the through hole, and an anti-slip groove is formed on the circumferential surface of the rotating block to increase friction.
[0016] Preferably, the claw can drive the spring to switch to a stretched state during operation.
[0017] By employing the above technical solution, this utility model provides an intelligent absorption bottle for liquid absorption methods that prevents backflow and evaporation. It possesses at least the following beneficial effects:
[0018] (1) This utility model achieves the effect of rotating the rotating block and rotating the ball and rotating rod by cooperating with each other. By rotating the rotating block, the rotating block drives the rotating rod to rotate, which in turn drives the ball to rotate inside the long tube. This changes the contact area between the ball and the inner wall of the long tube, thereby adjusting the flow rate and velocity of the liquid in the tube. This avoids the need for long sampling time to obtain a detectable amount for low-concentration samples, which may lead to solvent evaporation and changes in concentration, thus improving the detection efficiency.
[0019] (2) This utility model achieves the effect of rotating the rod and driving the wheel to rotate when the rod rotates. When the wheel rotates clockwise, it can rotate normally. When the wheel rotates counterclockwise, the serrations on the wheel will be obstructed by the serration, thus restricting the wheel and achieving the effect of limiting the ball in the long tube, preventing it from rotating due to external forces, and ensuring the accuracy of the test data.

[0029] 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.
[0030] Example 1
[0031] A smart absorption bottle for liquid absorption methods that prevents backflow and evaporation, such as... Figure 1 - Figure 6 As shown, the device includes an absorption bottle mechanism 1, which includes a bottle body 101. A bottle cap 102 is threadedly connected to the top of the bottle body 101. A long tube 103 is fixedly inserted through the top of the bottle cap 102, and a short tube 104 is fixedly inserted through the top of the bottle cap 102. The device also includes a flow regulating mechanism 2 for regulating the flow inside the long tube 103 and a limiting mechanism 3 for limiting the flow regulating mechanism 2. The flow regulating mechanism 2 includes a rotating rod 204. One end of the rotating rod 204 passes through the long tube 103 and is rotatably connected to the long tube 103. The other end of the rotating rod 204 away from the long tube 103 passes through a wheel 301 and is fixedly connected to the wheel 301.
[0032] The flow regulating mechanism 2 also includes a ball 201. A groove 203 is provided on the inner wall of the long tube 103 to cover the ball 201. A through hole 202 is provided on the outer surface of the ball 201 for conveying liquid. A rotating block 205 is fixedly connected to the end of the rotating rod 204 away from the long tube 103. The fixed connection between the rotating rod 204 and the rotating block 205 as described above realizes that rotating the rotating rod 204 can be driven to rotate synchronously by rotating the rotating block 205.
[0033] The end of the rotating rod 204 away from the rotating block 205 is fixedly connected to the circumferential surface of the ball 201. When the rotating block 205 rotates, it can drive the ball 201 to rotate through the rotating rod 204. The ball 201 is located inside the long tube 103. The above design, through the fixed connection between the rotating rod 204 and the ball 201, realizes that when the rotating rod 204 rotates, it drives the ball 201 to rotate inside the long tube 103.
[0034] The outer surface of the sphere 201 is in contact with the inner wall of the groove 203. The inner wall of the long tube 103 is located on the displacement trajectory of the through hole 202. When the sphere 201 rotates, it can change the contact area between the through hole 202 and the inner wall of the long tube 103. The above design, through the mutual contact between the sphere 201 and the inner wall of the groove 203, ensures the sealing of the inside of the long tube 103 when it is necessary to stop the liquid delivery.
[0035] The bottle body 101 is made of glass, and the bottle cap 102 is made of high-density polyethylene. The above design achieves good acid resistance and thermal stability through the glass bottle body 101.
[0036] The inner wall of the groove 203 is located on the displacement trajectory of the through hole 202. The circumferential surface of the rotating block 205 is provided with an anti-slip groove to increase friction. The above design, through the anti-slip groove on the circumferential surface of the rotating block 205, prevents the operator from slipping when rotating the rotating block 205.
[0037] Example 2
[0038] like Figure 5 - Figure 7 As shown, the limiting mechanism 3 includes a short rod A302. One end of the short rod A302 is fixedly connected to the circumferential surface of the long tube 103. The end of the short rod A302 away from the long tube 103 is rotatably connected to a claw 303. A short rod B304 is fixedly connected to the outer surface of the long tube 103. A spring 305 is fixedly connected to the end of the short rod B304 away from the long tube 103. The end of the spring 305 away from the short rod B304 is fixedly connected to the bottom of the claw 303. The above design achieves the limiting of the ball 201 through the mutual cooperation of the claw wheel 301 and the claw 303.
[0039] The inclined surface of the thorn teeth on the thorn wheel 301 is in contact with the thorn claw 303. When the thorn wheel 301 rotates, it can push the thorn claw 303 to rotate around the short rod A302 as the origin through the thorn teeth. The thorn wheel 301 and the thorn claw 303 mesh with each other. When the thorn wheel 301 rotates clockwise, it will be limited by the thorn claw 303. The above design realizes that the rotating rod 204 can only rotate in one direction through the mutual meshing of the thorn wheel 301 and the thorn claw 303.
[0040] Short rod B304 is located below short rod A302, and thorn wheel 301 is located between rotating block 205 and long tube 103. When moving, thorn claw 303 can be reset by spring 305 on short rod B304. The above design achieves the positioning of spring 305 by short rod B304 located below short rod A302.
[0041] When the claw 303 is running, it can drive the spring 305 to switch to a stretched state. The above design realizes the reset of the claw 303 through the stretched spring 305.
[0042] This invention relates to an intelligent absorption bottle for liquid absorption methods that prevents backflow and evaporation. In use, when liquid absorption is required, the gas or liquid to be measured enters the bottle body 101 through the long tube 103. By manually rotating the rotating block 205, the rotating block 205 drives the rotating rod 204 to rotate synchronously, causing the sphere 201 fixed to the end of the rotating rod 204 to rotate inside the long tube 103. The sphere 201 has a through hole 202 on its surface. By rotating the sphere 201, the relative position and contact area between the through hole 202 and the inner wall of the long tube 103 can be changed, thereby achieving precise adjustment of the fluid flow rate and velocity, effectively preventing solvent evaporation due to excessively long sampling times. Regarding the issue of concentration changes, during the adjustment process, the rotating rod 204 drives the ratchet 301 to rotate synchronously. When the ratchet 301 rotates clockwise, the pawl 303 can slide along the inclined plane. If an attempt is made to rotate counterclockwise, the pawl 303 will engage and lock with the ratchet teeth of the ratchet 301 under the reset action of the spring 305, preventing the rotating rod 204 and the ball 201 from rotating unexpectedly and ensuring the stability of the flow setting. The bottle body 101 is made of glass to ensure corrosion resistance and thermal stability, and the bottle cap 102 is made of high-density polyethylene to ensure sealing. The overall structure achieves intelligent flow control while also having the dual functions of preventing backflow and preventing evaporation, significantly improving the accuracy of detection data and operational efficiency.
