[0031] The inner wall of the side of the test box 1 is provided with an adjusting groove 2, the inner side of the adjusting groove 2 is movably provided with an adjusting rod 3 integrally fixed with the vertical cover body 4, the side of the adjusting groove 2 is screwingly locked with a locking bolt 11, the refrigeration one end of the semiconductor refrigerator 8 is located inside the test box 1, the heat dissipation one end of the semiconductor refrigerator 8 is provided with a heat dissipation base 9, one side of the heat dissipation base 9 is provided with a heat dissipation fan 10 for air cooling the heat dissipation one end of the semiconductor refrigerator 8, and the outer side of the test box 1 is provided with a controller 12.

[0032] According to the above embodiment, the working principle of the application is:

[0033] The temperature control principle is that when it is needed to increase the temperature of the heat resistance test liquid in the test box 1, the controller 12 sends a command, the resistance heating ring 7 is powered to generate heat, and the heat is transferred to the test liquid, so as to increase the temperature in the test box 1, and simulate the use scene of the suction pipe in a high temperature environment. When it is needed to reduce the temperature, the semiconductor refrigerator 8 is started, the refrigeration one end of the semiconductor refrigerator 8 is located inside the test box 1, absorbs the heat of the test liquid, and realizes the refrigeration of the test liquid. The heat dissipation one end of the semiconductor refrigerator 8 is provided with a heat dissipation base 9, and the heat dissipation fan 10 is used for air cooling the heat dissipation base 9, so as to ensure the normal work of the semiconductor refrigerator 8, stably reduce the temperature in the test box 1, and simulate a low temperature environment.

[0034] The straw positioning principle is that the straw positioning structure 5 is installed on the inner side of the vertical cover body 4. When the straw needs to be clamped and positioned, the inner tube wall of the straw is sleeved on the outer part of the positioning screw plate 509, the cross handle 508 is rotated, the driving rod 503 is driven to rotate, the bevel gear two 507 fixed at the top end of the driving rod 503 is rotated, the bevel gear two 507 is engaged with the bevel gear one 506, and the four screw rods 505 are synchronously rotated. Since the positioning screw plate 509 is arranged on the outer side of the screw rod 505 in a spiral transmission mode, when the screw rod 505 rotates, the positioning screw plate 509 moves along the radial direction on the screw rod 505. By adjusting the position of the positioning screw plate 509, the clamping and positioning of the straw with different inner diameters can be realized, and the position of the straw is stable during the test.

[0035] The overall operation control principle is that the adjusting groove 2 on the side inner wall of the test box 1 cooperates with the adjusting rod 3 on the vertical cover body 4, so that the height of the vertical cover body 4 can be adjusted. After being adjusted to a suitable position, the vertical cover body 4 is fixed by screwing the locking bolt 11. The controller 12 serves as the control core of the whole device and can centrally control the resistance heating ring 7, the semiconductor refrigerator 8, the heat dissipation fan 10 and other equipment, set and maintain the required temperature during the test, and realize the accurate test on the temperature resistance of the straw.
