The conditions in the embodiments can be further adjusted according to specific conditions. Any simple improvement of the method of the present utility model under the premise of the conception of the present utility model belongs to the protection scope required by the present utility model.

[0020] Please refer to Figures 1-3, the present utility model provides a constant temperature heating box that is convenient for temperature adjustment, including a box body 1 and an auxiliary cooling component 2.

A thermostat for regulating the heater 12 is also installed inside the box body 1. The inside of the heating chamber 11 can be heated by the heater 12. This is the well-known technology of the constant temperature heating box and will not be elaborated here. A plurality of slide rails 14 are fixedly connected to the inner side wall of the heating chamber 11. A placement mesh plate 15 is slidably installed on the slide rails 14. By installing the placement mesh plate 15 on different slide rails 14, the position of the placement mesh plate 15 can be adjusted. Items can be placed on the placement mesh plate 15 for heating. A temperature sensor 17 is fixedly installed on the inner top wall of the heating chamber 11. Through the setting of the temperature sensor 17, the temperature change inside the heating chamber 11 can be monitored in real time. A sealing door is hinged to the front of the box body 1 where the heating chamber 11 is located, and the heating chamber 11 can be sealed.

[0021] On one side of the box body 1 where the heating chamber 11 is located, a cooling water tank 13 is provided. At the top of the cooling water tank 13, there is a water inlet. The auxiliary cooling component 2 includes a cooling pipe 21 fixedly installed in the cooling water tank 13. One end of the cooling pipe 21 is fixedly installed with a blower 22. The other end of the cooling pipe 21 communicates with the heating chamber 11. An exhaust hole is provided on one side of the heating chamber 11. Through the setting of the auxiliary cooling component 2, when it is necessary to lower the heating temperature, first adjust the heating temperature of the heater 12, and then start the blower 22 to make the blower 22 deliver air into the cooling pipe 21. The air in the cooling pipe 21 is cooled after passing through the cooling water tank 13, so that the cold air is blown from the cooling pipe 21 into the heating chamber 11 to quickly cool the inside of the heating chamber 11. Thus, the temperature inside the heating chamber 11 can quickly reach the set temperature, saving time and improving the use effect of the constant temperature heating box; A heat conducting plate 23 is fixedly installed on the back of the cooling water tank 13. A refrigeration chip 24 is adhesively attached to the surface of the heat conducting plate 23. A heat sink 25 is fixedly connected to the surface of the refrigeration chip 24.

A protective net 28 is fixedly installed on one side of the back of the box body 1 close to the heat dissipation fan 26. Through the setting of the protective net 28, the heat dissipation fan 26 can be protected.

[0023] Among them, a check valve 29 is installed at one end of the cooling pipe 21 close to the heating chamber 11. Through the setting of the check valve 29, the hot air in the heating chamber 11 can be prevented from entering the cooling pipe 21. An insulating layer 16 is filled between the box body 1, the heating chamber 11 and the cooling water tank 13. Through the setting of the insulating layer 16, heat insulation can be achieved between the heating chamber 11 and the cooling water tank 13, reducing the heat exchange between the heating chamber 11 and the cooling water tank 13.

[0024] The working principle and usage process of the present utility model are as follows: First, through the setting of the auxiliary cooling component 2, when it is necessary to lower the heating temperature, first adjust the heating temperature of the heater 12, and then start the blower 22, so that the blower 22 conveys air into the cooling pipe 21. The air in the cooling pipe 21 is cooled after passing through the cooling water tank 13, and the cold air is blown from the cooling pipe 21 into the heating chamber 11 to quickly cool the heating chamber 11, so that the temperature in the heating chamber 11 can quickly reach the set temperature, saving time and improving the usage effect of the constant temperature heating box. Through the setting of the heat conducting plate 23, the refrigeration chip 24, the heat sink 25 and the radiator fan 26, the refrigeration chip 24 and the radiator fan 26 can be started, so that the cold end of the refrigeration chip 24 absorbs the heat of the heat conducting plate 23, and the cooling water in the cooling water tank 13 is cooled through the heat conducting plate 23, reducing the temperature of the cooling water and improving the cooling effect.
