[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The mass spectrometry detection and testing apparatus of this utility model according to embodiments is described below with reference to the accompanying drawings. Figures 1 to 10As shown, the mass spectrometry detection and testing device according to an embodiment of the present invention includes a reaction body 1, an isolation shell 2, a heating component 3, a temperature measuring component 7, and a cooling component 4.

[0028] The reaction body 1 includes a sample stage 11, which has a sample well 111 for receiving a sample. Specifically, the top of the sample stage 11 defines the sample well 111, and the opening of the sample well 111 faces upward to facilitate placing a sample. A temperature measuring component 7 is used to measure the wall temperature of the sample well 111. A heating component 3 is used to heat the sample stage 11.

[0029] The isolation shell 2 is detachably connected to the reaction body 1. The isolation shell 2 is sleeved on the outside of the sample stage 11. The inner wall surface of the isolation shell 2 and the wall surface of the sample tank 111 define a sealed cavity. The isolation shell 2 has an outlet 21 that communicates with the sealed cavity. The cooling component 4 is used to cool the isolation shell 2.

[0030] According to an embodiment of the present invention, the mass spectrometry detection device uses a heating component 3 to heat the sample stage 11, thereby heating the sample in the sample chamber 111. This facilitates the decomposition of the sample within the sealed cavity into gas, which can then be discharged from the outlet 21. A cooling component 4 cools the isolation shell 2 to reduce its temperature. Therefore, after testing, the isolation shell 2 can be quickly cooled, reducing the time required for personnel to disassemble it and improving testing efficiency. Furthermore, it prevents the isolation shell 2 from deforming due to high temperatures, increasing the service life of the mass spectrometry detection device.

[0031] Therefore, the mass spectrometry detection and testing device according to the embodiments of this utility model has improved testing efficiency and a long service life.

[0032] like Figures 1 to 4 As shown, in some embodiments, the sample stage 11 has a mounting cavity 112, and the heating element 3 is disposed within the mounting cavity 112. Specifically, the heating element 3 is an electric heating device, and an electric heating wire is provided in the mounting cavity 112, which extends spirally in the vertical direction. Thus, the sample stage 11 can be heated by the heating element 3, thereby heating the sample in the sample tank 111.

[0033] In some embodiments, the heating element 3 is spaced apart from the wall of the mounting cavity 112, and the mounting cavity 112 is filled with an insulating material, at least a portion of which is located between the heating element 3 and the wall of the mounting cavity 112. This prevents the heating element 3 from directly contacting the inner wall of the sample stage 11, thereby preventing leakage and damage to the sample stage 11. For example, the insulating material is an insulating powder.

[0034] In some embodiments, the bottom of the isolation shell 2 has a mounting port 22, through which the sample stage 11 extends into the isolation shell 2. Specifically, the sample stage 11 is a cylindrical body, and the shape and size of the cavity of the isolation shell 2 are adapted to the shape and size of the sample stage 11. The outer periphery of the cross-section of the sample stage 11 and the outer periphery of the cavity of the isolation shell 2 are both circular, so that the sample stage 11 extends into the isolation shell 2 through the mounting port 22, and the inner wall surface of the isolation shell 2 and the wall surface of the sample groove 111 define a sealing cavity.

[0035] like Figures 1 to 6 As shown, in some embodiments, the reaction body 1 further includes a first connecting ring 12, which is disposed on the periphery of the bottom of the sample stage 11. The first connecting ring 12 has a plurality of first connecting holes 121 spaced apart circumferentially. A second connecting ring 23 is disposed on the periphery of the bottom of the isolation shell 2. The second connecting ring 23 has a plurality of second connecting holes 24 spaced apart circumferentially, and the plurality of second connecting holes 24 correspond one-to-one with the plurality of first connecting holes 121 in the vertical direction. The first connecting ring 12 and the second connecting ring 23 are connected by fasteners 53 passing through the first connecting holes 121 and the second connecting holes 24. Thus, after the isolation shell 2 is fitted onto the outside of the sample stage 11, the first connecting ring 12 and the second connecting ring 23 are connected by the plurality of fasteners 53, thereby ensuring a stable connection between the isolation shell 2 and the sample stage 11. For example, the fasteners 53 are bolts. At least one of the second connecting holes 24 and the first connecting holes 121 is a threaded hole.

[0036] In some embodiments, a first seal 51 is provided between the first connecting ring 12 and the second connecting ring 23. For example, the first connecting ring 12 and the isolation shell 2 define an annular groove for receiving the first seal 51, which is a sealing ring.

[0037] In some embodiments, a first seal 51 is provided between the sample stage 11 and the isolation shell 2 to prevent gas leakage within the sealed cavity.

[0038] The gas outlet 21 is located on the top of the isolation shell 2. Specifically, the top of the isolation shell 2 has multiple gas outlets 21, each of which is equipped with a gas connector 61 and a gas outlet pipe 62 connected to the gas connector 61. This allows the gas generated in the sample cell 111 to be discharged outward through the gas outlet pipe 62. For example, the top of the isolation shell 2 has two gas outlets 21.

[0039] In some embodiments, a temperature measuring hole 25 is provided on the top of the isolation shell 2, and the temperature measuring component 7 extends into the sealed cavity through the temperature measuring hole 25 and contacts the wall of the sample tank 111. Specifically, a temperature measuring connector 71 is provided in the temperature measuring hole 25, and a temperature measuring sensor 72 is contacted with the wall of the sample tank 111, thereby facilitating the measurement of the temperature of the wall of the sample tank 111, and thus measuring the test temperature of the sample. For example, the temperature measuring component 7 is a thermocouple temperature measuring device.

[0040] like Figure 1 , Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, the cooling component 4 includes a cooling shell 41. The cooling shell 41 is fitted over the outside of the isolation shell 2 and defines a cooling cavity 42 with the isolation shell 2. The cooling cavity 42 is used to contain a cooling medium. The cooling shell 41 has a first inlet 43 and a first outlet 44 communicating with the cooling cavity 42. Thus, the cooling medium can be introduced into the cooling cavity 42 from the first inlet 43, then cool the isolation shell 2, and the cooled medium after heat exchange can be discharged from the first outlet 44. For example, the cooling cavity 42 is arranged around the periphery of the isolation shell 2, and the first inlet 43 is located below the first outlet 44. As another example, water is introduced into the cooling cavity 42 by a pump.

[0041] In some embodiments, the cooling shell 41 has stepped grooves 45 located on both sides of the cooling cavity 42 in the vertical direction. The stepped grooves 45 and the outer surface of the isolation shell 2 define a sealing groove 46, and a second sealing member 52 is provided in the sealing groove 46. Thus, the second sealing member 52 can seal the gap between the cooling shell 41 and the isolation shell 2, thereby preventing leakage of the cooling medium. For example, the second sealing member 52 is a sealing ring.
