Drawings
FIG. 1 is a general view of the structure of the present invention;
FIG. 2 is a cross-sectional view of the present invention;
in the figure: the device comprises a box body 1, a charging port 2, a limiting base 3, a circular groove 4, a cylindrical container 5, a pressure release valve 6, a box cover 7, a sealing area 8, heating cotton 9, a temperature measuring instrument 10, a heating knob 11, a refrigerating knob 12, a refrigerating device 13, a display screen 14 and a glass observation port 15.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the constant temperature sealing box for air sampling comprises a box body 1, a charging port 2 and a limiting base 3, wherein the limiting base 3 is fixed at the bottom in the box body 1 and is provided with a plurality of circular grooves 4; the device also comprises a cylindrical container 5, wherein the cylindrical container 5 is matched with the circular groove 4; the pressure relief valve 6 is arranged on the side wall of the box body 1; the top of the box body 1 is provided with a box cover 7, and the lower part of the box cover 7 is provided with a raised sealing area 8; the refrigerator further comprises a refrigerating device 13, wherein the refrigerating device 13 is fixed at the sealing area 8; still include the heating cotton 9, the heating cotton 9 is fixed in spacing base 3 bottom. Firstly, the constant temperature property of the most suitable temperature of the sample is ensured in the thermostat, therefore, the sealing area 8 of the box cover 7 and the limiting base 3 are both made of rubber, and besides the tightness, the limiting base 3 is provided with the circular groove 4, so that the contact area between the limiting base 3 and the sample is larger, and the temperature is also favorably kept. The heating cotton 9 and the refrigerating device 13 can be adjusted in time according to the requirement considering the different temperatures required by different solutions, and meanwhile, when the internal pressure of the heated box body 1 is too large, the pressure release valve 6 can be opened, so that the internal pressure of the box body 1 is kept in a normal range.
The temperature measuring device 10 is arranged at one end, far away from the pressure release valve 6, of the side wall of the box body 1. The refrigerator is characterized in that a heating knob 11 and a refrigerating knob 12 are arranged outside the refrigerator body 1, the heating knob 11 is connected with the heating cotton 9, and the refrigerating knob 12 is connected with the refrigerating device 13. The thermometer also comprises a display screen 14, and the display screen 14 is connected with the thermometer 10. The box body 1 is also provided with a glass viewing port 15 outside. The arrangement is convenient for operators to observe the state of the sample outside the box body 1 in time, the sample is not taken out in time, the sample can be normally processed, and the safety of the sample is ensured.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
