[0023] It also needs to be explained that, in the description of the utility model, unless otherwise explicitly specified and limited, the terms "set", "mount", "connected", "connected" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0024] As shown in Figures 1-4 The first chamber 2 and the second chamber 3 are provided above the box body 1, a plurality of through holes 4 are formed in the lower surfaces of the first chamber 2 and the second chamber 3, and a first electromagnetic valve 5 is arranged above each of the through holes 4; the two first electromagnetic valves 5 are used to respectively communicate the inside of a shell 6 with the first chamber 2 and the second chamber 3.

[0025] The shell 6 is fixedly installed above the box body 1, a semiconductor radiator 7 is fixedly installed in the shell 6, and the inside of the shell 6 is divided into a third chamber 8 and a fourth chamber 9; a second electromagnetic valve 11 is fixedly installed on the side of the third chamber 8 away from the fourth chamber 9; a fan 12 is fixedly installed at the top of the inside of the fourth chamber 9; a ventilation opening 13 is formed at the top of the inside of the fourth chamber 9; the heat dissipation end of the semiconductor radiator 7 is located in the third chamber 8; and the refrigeration end of the semiconductor radiator 7 is located in the fourth chamber 9.

[0026] Two ball screws 14 are fixedly installed in the inside of the box body 1, a support 15 is fixedly installed on the surface of the nut of each of the ball screws 14, and an oil-gas separation device 16 and a photoacoustic spectroscopy detector 17 are fixedly installed on the surfaces of the two supports 15, respectively.

[0027] The cabinet door 18 is hingedly connected to the two sides of the box body 1 and the temperature sensor 19 is installed in the inside of the box body 1.

[0028] In the embodiment one, when the temperature sensor 19 detects that the temperature inside the box 1 is higher than the preset temperature, the first electromagnetic valve 5 connected with the second chamber 3, the fan 12, the second electromagnetic valve 11 and the semiconductor radiator 7 are all opened, and the first electromagnetic valve 5 connected with the first chamber 2 is closed. The refrigeration end of the working semiconductor radiator 7 can reduce the temperature inside the fourth chamber 9, and then the cold air in the fourth chamber 9 is blown into the second chamber 3 through the fan 12, and the cold air in the second chamber 3 is uniformly blown into the box 1 through the plurality of through holes 4 to reduce the temperature. Since the heat dissipation end of the semiconductor radiator 7 also works when the semiconductor radiator 7 works, the second electromagnetic valve 11 is opened and the first electromagnetic valve 5 connected with the first chamber 2 is closed, so that the hot air in the third chamber 8 is discharged.

[0029] In the embodiment two, when the temperature sensor 19 detects that the temperature inside the box 1 is lower than the preset temperature, the first electromagnetic valve 5 connected with the first chamber 2 and the semiconductor radiator 7 are both opened, and the first electromagnetic valve 5 connected with the second chamber 3, the second electromagnetic valve 11 and the fan 12 are all closed. The heat dissipation end of the working semiconductor radiator 7 can increase the temperature inside the third chamber 8, the hot air in the third chamber 8 flows into the first chamber 2 through the first electromagnetic valve 5 connected with the first chamber 2, and finally the hot air in the first chamber 2 uniformly flows into the box 1 through the plurality of through holes 4 to increase the temperature. Since the first electromagnetic valve 5 connected with the second chamber 3 is closed, the cold air in the fourth chamber 9 cannot enter the box 1 and is discharged from the air vent 13.

[0030] In combination with the above two embodiments, it can be found that the present application can realize the constant temperature of the box 1 by controlling only three electromagnetic valves according to the fast heating and refrigeration response of the semiconductor radiator 7, so that the constant temperature of the box 1 can be realized in a short time. The constant temperature device in the prior art often needs a part of time to complete heating and refrigeration, such as air conditioner, heating wire, refrigerator and the like.

[0031] In the embodiment three, when the oil-gas separation device 16 and the photoacoustic spectrum detector 17 need to be taken out, the cabinet doors 18 on both sides of the box 1 are opened, and then the corresponding ball screws 14 are controlled to push the oil-gas separation device 16 or the photoacoustic spectrum detector 17 to the cabinet doors 18 through the ball screws 14, and then the oil-gas separation device 16 or the photoacoustic spectrum detector 17 is taken out.

[0032] The preferred embodiments of the present application have been described above, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical scheme falling within the idea of the present application belongs to the protection scope of the present application.
