[0027] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0028] like Figures 1-3 The diagram shows the structure of the airflow dryer for glass instruments of this invention, used for drying and cleaning glassware such as test tubes and beakers. Foot pads 2 are fixedly installed at the bottom of the housing 1 to support it. The cover plate 9 is fixed to the top of the housing 1 with screws. A sealing assembly is provided between the cover plate 9 and the top of the housing 1, which prevents internal heat loss, thus avoiding energy and cost waste; it also prevents water from flowing into the housing 1 along the cover plate 9 during drainage.

[0029] like Figure 4 As shown, the sealing assembly includes a boss 3, a sealing groove 4, a spring groove 5, a spring 6, a pressure plate 7, and a sealing gasket 8. The boss 3 is integrally connected to the outer circumference of the top of the housing 1. When the cover plate 9 is fixed to the housing 1, the fastening screw passes through the cover plate 9 and is screwed onto the boss 3. The sealing groove 4 is annular and is located on the side of the boss 3 closest to the housing 1. The spring groove 5 is located at the bottom of the sealing groove 4. There are at least two spring grooves 5, and the included angle between two adjacent spring grooves 5 is the same to ensure that the sealing gasket 8 is stably pressed against the lower surface of the cover plate 9 and to ensure that the force is evenly distributed (if two spring grooves 5 are provided at the bottom of the sealing groove 4, the included angle between the two spring grooves 5 is 180°; if three spring grooves 5 are provided at the bottom of the sealing groove 4, the included angle between the three spring grooves 5 is 120°, and so on).

[0030] The spring 6 is placed in the spring groove 5, the pressing plate 7 is placed in the sealing groove 4 and presses against the upper surface of the spring 6, and the sealing pad 8 is placed in the sealing groove 4 and presses against the upper surface of the pressing plate 7. By arranging the pressing plate 7 between the sealing pad 8 and the spring 6, it is ensured that the sealing pad 8 does not appear uneven when it is pressed against the lower surface of the pressing plate 7.

[0031] When the cover plate 9 is not installed, the sealing pad 8 is higher than the upper surface of the box body 1 by a distance, and after the cover plate 9 is fixed, the spring 6 is compressed so that the sealing pad 8 is flush with the upper surface of the box body 1. Since the spring 6 is in a compressed state, it will continuously provide upward pressure to ensure that the sealing pad 8 is tightly pressed against the lower surface of the cover plate 9, thereby improving the sealing performance. This can not only avoid the loss of internal heat to the outside, thereby wasting energy and cost, but also avoid water flowing along the cover plate 9 into the box body 1 when draining.

[0032] The collecting groove 10 is arranged at the top of the cover plate 9, and the collecting groove 10 is not arranged horizontally, but one side is high and the other side is low. This facilitates the timely drainage of water flowing into the collecting groove 10 from test tubes, beakers and the like, thereby avoiding the accumulation of water. The through hole 11 penetrates the cover plate 9 and is connected to the lowest part of the collecting groove 10. The collecting box 13 is fixed to one side of the box body 1, and the flow guide pipe 12 is inserted into the through hole 11 at one end and into the collecting box 13 at the other end. The accumulated water in the collecting groove 10 flows to the through hole 11 under the action of the height difference, and then flows into the collecting box 13 through the flow guide pipe 12.

[0033] The sealing plate 14 is integrally connected to the top of the cover plate 9 and is arc-shaped, with the center of the arc facing the box body 1. Water flowing to the sealing plate 14 from test tubes or beakers and the like will flow along the surface of the arc-shaped sealing plate 14 to the collecting groove 10, thereby avoiding the accumulation of water on the surface of the sealing plate 14.

[0034] The insertion cylinder 15 is annularly arranged at the top of the sealing plate 14, and the insertion hole 16 penetrates the insertion cylinder 15 and is in communication with the box body 1. This facilitates the hot air inside to enter the drying tube 17 through the insertion hole 16, so as to dry the test tubes, beakers and other glassware devices sleeved on the drying tube 17. Figures 1-3 As shown in the figure, the insertion cylinder 15 is arranged obliquely, so the drying tube 17 inserted into the insertion cylinder 15 is also arranged obliquely. When the test tube is sleeved on the drying tube 17, the test tube will be obliquely pressed against the side wall of the drying tube 17, thereby avoiding the shaking of the test tube, beaker and the like.

[0035] As shown in the figure, the insertion cylinder 15 is arranged obliquely, so the drying tube 17 inserted into the insertion cylinder 15 is also arranged obliquely. When the test tube is sleeved on the drying tube 17, the test tube will be obliquely pressed against the side wall of the drying tube 17, thereby avoiding the shaking of the test tube, beaker and the like. Figure 5 , 6As shown, it is a structural schematic diagram of the drying tube 17, the air groove 18 penetrates the drying tube 17 along the axial direction of the drying tube 17, and the outer diameter of the drying tube 17 is equal to the diameter of the insertion hole 16. In actual assembly, the drying tube 17 is inserted into the insertion hole 16 of the insertion cylinder 15. The air groove 18 of the drying tube 17 is communicated with the inside of the box body 1 through the insertion hole 16. The hot air in the box body 1 enters the drying tube 17 through the insertion hole 16 to dry the glassware such as test tubes and beakers sleeved on the drying tube 17.

[0036] When the drying tube 17 is inserted into the insertion cylinder 15, the length of the drying tube 17 inserted into the insertion cylinder 15 is not less than half the length of the insertion cylinder 15, so as to avoid the drying tube 17 from falling out of the insertion cylinder 15 and breaking the glassware such as test tubes and beakers. The exhaust hole 19 is annularly arranged on the circumferential surface of the drying tube 17 and is communicated with the air groove 18. The hot air in the box body 1 enters the drying tube 17 through the insertion hole 16, and then flows to the inside of the test tube through the exhaust hole 19 to dry the glassware such as test tubes and beakers sleeved on the drying tube 17.

[0037] The abutting plate 20 is fixed on the bottom of the drying tube 17. When the drying tube 17 is inserted into the insertion cylinder 15, the abutting plate 20 abuts against the upper surface of the insertion cylinder 15 to limit the inserted drying tube 17. The flow guide plate 21 is fixed on the circumferential surface of the abutting plate 20 and is arranged obliquely downward. The oblique flow guide plate 21 can guide the water falling on the surface of the drying tube 17 outward to the sealing plate 14 or the collecting groove 10, so as to avoid the water from flowing to the inside of the box body 1 through the gap between the drying tube 17 and the insertion cylinder 15.

[0038] The insertion rod 22 is inserted into the end of the drying tube 17 away from the abutting plate 20. The rod cap 23 is integrally connected to the top of the insertion rod 22. The arc-shaped part 24 is arranged on the circumferential surface of the rod cap 23. The material of the insertion rod 22 and the rod cap 23 is rubber. When the test tubes, beakers and the like are sleeved on the drying tube 17, the inner side and bottom of the test tubes, beakers and the like will contact the rod cap 23, so as to avoid scratching the glassware such as test tubes and beakers.

[0039] The first extension rod 25 is integrally connected to one side of the drying tube 17. The second extension rod 26 is integrally connected to the first extension rod 25 and extends away from the insertion cylinder 15. The second extension rod 26 is parallel to the drying tube 17. When the slender glassware such as test tubes is inserted into the drying tube 17, the inclined test tube will abut against the second extension rod 26 to improve the stability of the test tube. When the glassware such as beakers with large opening and large diameter is inserted into the drying tube 17, it can be inserted into the adjacent second extension rod 26 due to its large diameter, so as to improve the stability.

[0040] The inside of the box body 1 is provided with an electric heating wire. A fan is installed below the electric heating wire. The heat generated by the electric heating wire after being electrified is blown into the drying tube 17.
