DETAILED DESCRIPTION

[0026] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0027] Example 1, refer to Figures 1-8For the first embodiment of the present application, the embodiment provides a water bath nitrogen blowing instrument, which can realize the effect of automatically correcting the position of the long straight pipe 106 when the long straight pipe 106 enters the test tube 102, and comprises a supporting part 100, a water bath nitrogen blowing instrument body 101, a plurality of test tubes 102 arranged on the water bath nitrogen blowing instrument body 101, a mounting disc 103 arranged on the water bath nitrogen blowing instrument body 101, a plurality of notches 104 arranged on the mounting disc 103, a pump tube 105 arranged in the notch 104, and a long straight pipe 106 arranged at the lower end of the pump tube 105; an adaptive part 200, comprising a first guide assembly 201 arranged on the pump tube 105, a second guide assembly 202 arranged on the first guide assembly 201, a guide assembly 203 arranged on the long straight pipe 106, and a stop assembly 204 arranged on the long straight pipe 106; a gas permeable part 300, comprising a pushing assembly 301 arranged on the guide assembly 203, a blocking assembly 302 arranged on the guide assembly 203, and a transmission assembly 303 arranged on the pushing assembly 301; a dismounting part 400, comprising a resilient assembly 401 arranged on the guide assembly 203, and a clamping assembly 402 arranged on the long straight pipe 106.

[0028] Specifically, the water bath nitrogen blowing instrument body 101 is provided with a plurality of elastic clamps, which can fix the test tube 102, and hot water is arranged at the lower end of the water bath nitrogen blowing instrument body 101, which can warm the test tube 102. This is a prior art and will not be described here. The length and width of the plurality of notches 104 are greater than the length and width of the pump tube 105, so that the pump tube 105 will not collide with the inner wall of the notch 104 when adjusting the position. In use, the long straight pipe 106 is inserted into the test tube 102 to provide nitrogen gas for the liquid in the test tube 102.

[0029] Further, the first guide assembly 201 comprises a plurality of connecting plates 201a fixedly connected to the plurality of pump tubes 105, the connecting plate 201a is provided with a guide groove 201b, the T-shaped block 201c is slidably connected in the guide groove 201b, and the T-shaped block 201c is elastically connected with the inner wall of the guide groove 201b through the first spring 201d; the second guide assembly 202 comprises a plurality of arc-shaped grooves 202a arranged on the mounting disc 103, the T-shaped block 201c is elastically connected with the inner wall of the arc-shaped groove 202a through the second spring 202b, the inner walls of the arc-shaped groove 202a and the guide groove 201b are both provided with anti-falling grooves 202c, and the T-shaped block 201c is fixedly connected with an anti-falling block 202d matched with the anti-falling groove 202c.

[0030] The setting of the anti-falling groove 202c and the anti-falling block 202d can avoid the anti-falling block 202d from falling off, thereby avoiding the automatic inclination of the pump tube 105 and affecting the insertion of the long straight tube 106 into the test tube 102. The setting of the second spring 202b and the first spring 201d can make the pump tube 105 automatically reset and prevent the position of the pump tube 105 from being too far from the center of the test tube 102 in the next use.

[0031] Preferably, the guide assembly 203 comprises a cone 203a arranged on the sidewall of the long straight tube 106, the cone 203a is provided with a round mouth 203b for the long straight tube 106 to pass through, the cone 203a is provided with a plurality of bevels 203c, the cone 203a is provided with a plurality of vertical edges 203d corresponding to different diameters of the cone 203a; the stop assembly 204 comprises a threaded groove 204a arranged on the long straight tube 106, and a threaded ring 204b threadedly connected to the threaded groove 204a.

[0032] It should be noted that the vertical edges 203d correspond to different diameters of the cone 203a, thereby being applicable to test tubes 102 with different diameters. The setting of the threaded groove 204a allows the position of the threaded ring 204b to be adjusted, thereby being applicable to test tubes 102 with different lengths.

[0033] In use, after the test tube 102 is placed on the water bath nitrogen purging instrument body 101, the program is set, the control of the pump tube 105 is carried out, the mounting disc 103 is lowered, the long straight tube 106 at the lower end of the plurality of pump tubes 105 is inserted into the liquid surface in the test tube 102, and nitrogen is provided for the liquid in the test tube 102. When the long straight tube 106 is inserted into the test tube 102, the inclined surface on the conical body 203a first abuts against the inner wall of the test tube 102. At this time, the conical body 203a is offset by continuing to move downward, and the correction of the long straight tube 106 is automatically carried out. In this process, the T-shaped block 201c slides in the guide groove 201b and the arc-shaped groove 202a, and the balance of displacement in different directions is carried out to avoid the phenomenon that the pump tube 105 is stuck. At the same time, the setting of the anti-falling groove 202c and the anti-falling block 202d can avoid the situation that the anti-falling block 202d falls off and the pump tube 105 falls off. When the vertical edge 203d on the conical body 203a abuts against the inner wall of the test tube 102, the inclined surface with a larger diameter at the upper end abuts against the upper end surface of the test tube 102. At this time, the correction process is completed. When the test tube 102 is longer, only the threaded ring 204b needs to be rotated to move upward. At this time, although the inclined surface with a larger diameter at the upper end of the conical body 203a abuts against the upper end surface of the test tube 102, since there is a distance between the conical body 203a and the stop ring, the conical body 203a can continue to move upward to ensure that the long straight tube 106 can be inserted into the liquid surface in the test tube 102. At the same time, when the conical body 203a is pressed against the inner wall of the test tube 102, the test tube 102 is pressed between the bottom of the water bath nitrogen purging instrument body 101 and the conical body 203a, which can also ensure the stability of the limiting position of the test tube 102 during detection.

[0034] In summary, by setting the self-adaptive component 200, the inclined edge 203c of the conical body 203a cooperates with the side wall of the test tube 102 during the insertion of the long straight tube 106 into the test tube 102, and the position of the long straight tube 106 can be corrected. Therefore, the experimental personnel do not need to specially rotate the screw to adjust the position of the long straight tube 106, and the use is more convenient.

[0035] Example 2, refer to Figures 1-7For the second embodiment of the present application, unlike the previous embodiment, the embodiment provides a water bath nitrogen blowing instrument air permeable component 300, which solves the problem of how to ensure the air permeability of the test tube 102 inside, which includes a pushing assembly 301, including a horizontal groove 301a arranged in the conical body 203a, a communication groove 301b is arranged in communication with the horizontal groove 301a, a lifting plate 301c is slidably connected in the horizontal groove 301a, the lifting plate 301c is elastically connected with the inner wall of the horizontal groove 301a through the third spring 301d, and the communication groove 301b is slidably connected with the top rod 301e fixed with the lifting plate 301c; the plugging assembly 302 includes a plurality of Z-shaped openings 302a arranged in the conical body 203a, the upper and lower ends of the Z-shaped opening 302a are provided with extension grooves 302b, and the extension grooves 302b are slidably connected with the plugging blocks 302c; the transmission assembly 303 includes a mounting cavity 303a arranged in the extension groove 302b, the mounting cavity 303a is communicated with the horizontal groove 301a, the lifting plate 301c is provided with two mounting holes 303b, the mounting holes 303b are provided with guide grooves 303c, the guide grooves 303c are provided with guide rods 303d, the guide rods 303d are fixedly connected with vertical plates 303e, and the vertical plates 303e penetrate through the mounting cavity 303a and are fixedly connected with the plugging blocks 302c.

[0036] Specifically, since nitrogen is pumped into the test tube 102 all the time, in order to avoid explosion due to high gas pressure, the Z-shaped opening 302a is arranged here to avoid dust falling directly into the test tube 102 from the upper end of the conical body 203a, which affects the experimental results.

[0037] In use, the threaded ring 204b is spaced apart from the upper end face of the cylinder, the plugging block 302c is plugged in the upper and lower ends of the Z-shaped opening 302a when the conical body 203a is not in contact with the test tube 102, which can prevent dust from entering the Z-shaped opening 302a, when the lower end of the conical body 203a is in contact with the test tube 102, since the conical body 203a cannot continue to move downward, when the straight pipe 106 continues to move downward, the conical body 203a approaches the threaded ring 204b, so that the threaded ring 204b is in contact with the top rod 301e, which drives the lifting plate 301c to move downward, at this time, the guide groove 303c cooperates with the guide rod 303d, which can drive the vertical plate 303e to move away from the Z-shaped opening 302a, so that the Z-shaped opening 302a is opened, thereby realizing that the conical body 203a can still be exhausted when it blocks the upper end of the test tube 102, which can avoid the explosion of the test tube 102 due to the gas pressure problem, the length of the top rod 301e extending to the upper side of the conical body 203a is greater than the distance between the lifting plate 301c and the inner wall of the horizontal groove 301a, so that the conical body 203a and the threaded ring 204b cannot be in contact, which can avoid the phenomenon that the test tube 102 cannot be exhausted.

[0038] In summary, by setting the air-permeable part 300, when the cone 203a is on the test tube 102, it can also drive the ejector rod 301e to move, so that the vertical plate 303e moves, drives the blocking block 302c to separate from the Z-shaped opening 302a, so that the Z-shaped opening 302a is opened, ensuring that the gas in the test tube 102 can be discharged, avoiding the phenomenon of cracking caused by the high gas pressure in the inner wall of the test tube 102.

[0039] Embodiment 3, refer to Figures 1-8 The third embodiment of the present application is different from the previous embodiment. The embodiment provides a disassembly part 400 of the water bath nitrogen blowing instrument, which solves the problem of how to disassemble the cone 203a. It comprises an elastic assembly 401, which comprises a containing groove 401a arranged in the cone 203a, a sliding block 401b slidingly connected in the containing groove 401a, the sliding block 401b being elastically connected with the inner wall of the containing groove 401a through a fourth spring 401c, a push block 401d fixedly connected on the sliding block 401b, a clamping assembly 402 comprising an L-shaped groove 402a arranged on the side wall of the long straight tube 106, the L-shaped groove 402a being provided with a cut edge 402b and a clamping groove 402c, and a friction frame 402d fixedly connected on the push block 401d and matched with the L-shaped groove 402a and the clamping groove 402c.

[0040] Specifically, the length of the clamping groove 402c is greater than the distribution length of the threaded groove 204a on the long straight tube 106, so that when the cone 203a moves, the clamping groove 402c will not be clamped with the push block 401d to affect the movement of the cone 203a.

[0041] In use, when the cone 203a does not need to be disassembled, the push block 401d slides in the clamping groove 402c, at this time the push block 401d goes straight up and down without affecting the sliding of the cone 203a. The setting of the friction frame 402d can avoid the automatic dislocation of the push block 401d and the clamping groove 402c. When the cone 203a needs to be disassembled and replaced (periodic cleaning and replacement), only need to rotate the cone 203a so that the cone 203a is dislocated with the clamping groove 402c, and the push block 401d is rotated to the vertical edge 203d of the L-shaped groove 402a, at this time the cone 203a is pushed down to extract the cone 203a. The setting of the cut edge 402b avoids the clamping phenomenon between the push block 401d and the cut edge 402b, ensuring that the cone 203a can be directly poked and removed.

[0042] In summary, by setting the disassembly part 400, when cleaning or replacing the cone 203a, only need to poke the cone 203a so that the push block 401d on the cone 203a is opposite to the vertical edge 203d of the L-shaped groove 402a, and then press down the cone 203a, so that the cone 203a can be disassembled.

[0043] It should be noted that the above examples are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced, without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
