[0023] like Figure 1-3As shown, an ignition, oxygen filling and degassing mechanism of an oxygen bomb includes an oxygen bomb cylinder 1, an oxygen bomb seat 2 and a laser head 19. A hanging head 3 is provided on the top of the oxygen bomb cylinder 1, and the laser head 19 is suspended directly above the hanging head 3.

A quartz lens 2 18 is provided inside the inner sealing block 16, and a flat sealing gasket 2 17 is in contact with the quartz lens 2 18. A sealing ring 2 13 is provided on the oxygen bomb seat 2, and the sealing ring 2 13 is in contact with the oxygen bomb cylinder 1. A crucible support base 4 is provided on the oxygen bomb seat 2, a crucible support base 4 is provided on the crucible support base 4, a crucible support 5 is provided on the crucible support 5, a crucible 6 is provided on the crucible support 5, a sealing ring 1 8 is provided on the oxygen bomb seat 2, and a sealing valve 7 is provided on the oxygen bomb seat 2, and the sealing valve 7 is in contact with the sealing ring 1 8. An O-ring 11 is provided on the bomb seat 2, an oxygenating head 9 is provided on the oxygen bomb seat 2, a venting plug 10 is provided inside the oxygenating head 9, a gas joint 12 is provided inside the oxygenating head 9, and a hexagonal nut 20 is provided on the gas joint 12. In this embodiment, when in use, the oxygen bomb seat 2 is first placed on the base with the oxygenating head 9, and then the crucible 6 with the weighed sample is placed on the crucible stand 5, and the oxygen bomb cylinder 1 is screwed on. Oxygen enters the oxygen bomb through the oxygenating head 9 and the sealing valve 7, and 3MPa of oxygen is filled. After the oxygen bomb is filled, it is placed in the instrument for testing. When the ignition conditions are met, the orientation setting of the laser head 19 can ensure that when the oxygen bomb rotates in different directions, the laser head 19 emits a laser, which, in cooperation with the suspension head 3, quartz lens 15 and quartz lens 2 18, can directly irradiate the test sample in the crucible 6 and ignite the sample. After the test is completed, the oxygen bomb is removed from the instrument and placed on the base equipped with the oxygen filling head 9. The sealing valve 7 with the sealing ring 8 can be opened to achieve deflation.

[0024] like Figure 1-2 As shown, the oxygen bomb 1 and the oxygen bomb seat 2 are provided with a threaded connection, and the oxygen bomb seat 2 and the oxygen filling head 9 are provided with a threaded connection. In this embodiment, the connection between the oxygen bomb 1 and the oxygen bomb seat 2 facilitates the addition of the sample into the crucible, and the connection between the oxygen bomb seat 2 and the oxygen filling head 9 facilitates the degassing work.

[0025] like Figure 2-3 As shown, the number of the quartz lenses 18 is set to two, which are symmetrically arranged up and down. In this embodiment, the setting of the number allows the laser to be better refracted into the crucible to ignite the sample.

[0028] In summary, when in use, first place the oxygen bomb seat 2 on the base equipped with the oxygen filling head 9, then place the crucible 6 with the sample weighed on the crucible stand 5, screw on the oxygen bomb tube 1, and oxygen enters the oxygen bomb through the oxygen filling head 9 and the sealing valve 7. After filling with 3MPa of oxygen, put it into the instrument for testing. When the ignition condition is met, the orientation setting of the laser head 19 can ensure that when the oxygen bomb rotates in different directions, the laser head 19 emits a laser that can directly irradiate the test sample in the crucible 6 with the cooperation of the suspension head 3, the quartz lens 1 15 and the quartz lens 2 18, thereby igniting the sample. After the test is completed, the oxygen bomb is removed from the instrument. Then put it on the base equipped with the oxygen filling head 9, and open the sealing valve 7 with the sealing ring 8 to achieve deflation. The connection between the oxygen bomb 1 and the oxygen bomb seat 2 can facilitate the addition of samples into the crucible, and the connection between the oxygen bomb seat 2 and the oxygen filling head 9 facilitates the deflation work. By setting the number, it can better refract the laser into the crucible to ignite its sample. Chlororubber is a thermoplastic resin with multiple excellent properties, with the advantages of weather resistance, chemical stability, water resistance, chemical corrosion resistance and temperature resistance. There is no obstruction above the crucible 6, and the crucible 6 is convenient to take and place.
