Description

Technical Field

[0001] This utility model relates to the technical field of air-drying devices, and in particular to a rapid air-drying device for chemical test tubes. Background Technology

[0002] Test tubes are common instruments in chemistry laboratories, used as reaction containers for small amounts of reagents. They are used at room temperature or with heating. There are various types of test tubes, including ordinary test tubes, side-braced test tubes, and centrifuge tubes. Students use test tubes extensively in laboratory experiments and research. After use, test tubes retain residual reagents that were used, which adhere to the inner wall. Therefore, they need to be cleaned with detergent, rinsed with water, and then rinsed with distilled water. After cleaning, test tubes are usually dried in an air dryer.

[0003] Existing devices dry the inner walls of test tubes by inverting them onto the air ducts of a dryer and blowing hot air through the ducts. However, the test tubes vary in length, making it difficult for the air ducts to accommodate all test tubes of different depths. If the test tubes are too long, the drying efficiency decreases. Therefore, a dryer with adjustable length was designed to address the aforementioned problems. Utility Model Content

They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In current technology, existing devices dry the inner walls of test tubes by inverting them onto the air ducts of a dryer and blowing hot air through the ducts. However, test tubes vary in length, and the air ducts cannot accommodate all test tubes of different depths. If the test tubes are long, the drying efficiency will decrease.

[0026] As shown in the attached figure, this embodiment of the invention provides a rapid air-drying device for chemical test tubes.

[0027] The dryer body 11 includes: a duct 12 on the top of the dryer body 11; an adjustment assembly 2 on the duct 12, the adjustment assembly 2 including: an inner tube 21 disposed inside the duct 12; a sliding groove 22 formed on the inner side wall of the duct 12; a slot 23 formed on the inner side wall of the duct 12 and communicating with the inside of the sliding groove 22; and a protrusion 24 disposed on the outer side wall of the bottom end of the inner tube 21 and sliding inside the sliding groove 22 and the slot 23.

[0028] Specifically, the dryer body 11 works by removing moisture from the test tube through heating and ventilation. Specifically, the device uses a rotating fan to send hot air into the glass test tube, and the air is heated by a heating element before entering the test tube through the air inlet pipe. This allows the moisture inside the test tube to be discharged through the exhaust vent, thus achieving the drying purpose (the specific heating components described above are not shown in the accompanying drawings).

[0029] In use, simply control the inner tube 21 to rotate, causing the protrusion 24 at the bottom of the inner tube 21 to slide from the inside of the slot 23 to the inside of the slide groove 22, thus releasing the restriction on the protrusion 24. Then, drag the inner tube 21 to slide and adjust its height inside the air duct 12, while the protrusion 24 at the bottom of the inner tube 21 slides up and down inside the slide groove 22. After the inner tube 21 is adjusted to a suitable height, control the rotation of the inner tube 21 to drive the protrusion 24 at the bottom to rotate as well, sliding from the inside of the slide groove 22 to the inside of the slot 23. This can limit the up and down movement of the inner tube 21 and stabilize its position. Then, invert the test tube onto the inner tube 21 (the test tube is not shown in the attached figure), and hot air is supplied to the inside of the air duct 12 through the dryer body 11. The hot air is sprayed out from the through grooves on the outer wall of the inner tube 21 and the air duct 12 to dry the inside of the test tube.

[0030] In some embodiments, the adjustment assembly 2 further includes: an arc-shaped groove 25 formed on the outer side wall of the inner tube 21; a ring 26 sleeved on the outer side of the inner tube 21; an arc-shaped block 27 slidably disposed inside the arc-shaped groove 25 and fixedly connected to the inner side wall of the ring 26; a positioning hole 28 formed at the top end of the air duct 12; and a plug rod 29 fixedly disposed at the bottom of the ring 26.

[0031] After adjustment, the ring 26 can be pushed to slide on the inner tube 21, while the arc block 27 slides inside the arc groove 25 until the ring 26 is in contact with the top of the air duct 12. At the same time, the insertion rod 29 at the bottom of the ring 26 is inserted into the positioning hole 28 to restrict the rotation of the inner tube 21, making the protrusion 24 at the bottom of the inner tube 21 more stable inside the slot 23.

[0032] In some embodiments, the protrusion 24 is a cylindrical rod design.

[0033] The round rod has a smooth surface, which reduces friction when sliding.

[0034] In some embodiments, the adjustment component 2 further includes a cone 291 disposed at the bottom end of the insertion rod 29.

[0035] The pointed tip design at the bottom of the cone 291 makes it easier to insert into the positioning hole 28.

[0036] In some embodiments, the adjustment component 2 further includes a rubber ring 292 disposed at the top end of the inner tube 21.

[0037] The design of the rubber ring 292 prevents the top of the inner tube 21 from scratching the inside of the test tube when it comes into contact with the inner wall of the test tube.

[0038] In some embodiments, a limiting component 3 is provided on the outer side wall of the air duct 12. The limiting component 3 includes: a rotating rod 31 rotatably disposed on the outer side wall of the top end of the air duct 12; a stop block 32 disposed on the top end of the rotating rod 31; and a spring 33 with both ends connected to the rotating rod 31 and the outer side wall of the air duct 12.

[0039] Spring 33 rebounds and pushes rotating rod 31 to rotate, causing the stop block 32 at the top of rotating rod 31 to move to the top of ring 26, thus restricting the position of ring 26.

[0040] In some embodiments, the limiting component 3 further includes a protrusion 34 disposed on the outer side wall of the spring 33.

[0041] The design of the protrusion 34 can increase friction when the rotating rod 31 is pressed to rotate.

[0042] In some embodiments, the limiting components 3 are symmetrically arranged in two sets.

[0043] The two-piece design makes it easy to press; simply place your index finger and thumb on the rotating rod 31 and pinch it to rotate. This makes it easier to operate and also improves the restriction on the ring 26.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
