[0003] Patent No. CN118425212A discloses a sample protection device, including a sample base, a first groove is formed on the top of the sample base, and the sealing cover plate seals the first groove when it is buckled on the sample base. A clamping rod is arranged on the sample base, and the clamping rod abuts against the upper side of the sealing cover plate. A negative pressure driving mechanism is arranged on the sample base to drive the clamping rod to move away from the upper side of the sealing cover plate.

[0046] In the embodiment of the present invention, the specific working principles of the energy analyzer 4, the ion pump 5, the ion gauge 6, and the molecular pump 7 refer to patent CN218956453U3, and will not be described in detail. The first sealing plate 312 and the second sealing plate 313 are used to seal the injection port 9 from the inner and outer sides respectively to prevent external air from entering the analysis chamber 2. When the second electric telescopic rod 333 drives the second key bar 3324 to be located in the first key groove 342, the third bevel gear 3321 is disengaged from the first bevel gear 317. When the second electric telescopic rod 333 drives the second key bar 3324 to be located in the accommodating chamber 347, the tooth groove 353 is transmission-connected with the second transmission gear 3322.

[0047] See also Fig. 9 , Figure 10-Figure 14In one embodiment of the present invention, the sample placing portion 35 includes a sample placing dish 351, a bracket 352, a clamping member 354 and a tooth groove 353. The sample placing dish 351 is fixedly connected to the bracket 352. The surface of the bracket 352 is provided with a tooth groove 353.

The tooth groove 353 is in transmission connection with the second transmission gear 3322. The clamping member 354 is connected to the bracket 352.

[0048] See also Figure 7 and Fig.10 Furthermore, a limit frame 345 is provided on the inner wall of the rotating frame 34, and both sides and the bottom of the bracket 352 are in contact with the limit frame 345. A gas detection probe 343 is fixedly connected to the position of the inner wall of the rotating frame 34 corresponding to the fourth central tube 344.

[0049] In an embodiment of the present invention, when the tooth groove 353 is disengaged from the second transmission gear 33, the limit frame 345 plays the role of supporting the bracket 35 and the sample dish 351, and the gas detection probe 343 is communicated with the control display to monitor the gas composition passing through the fourth center tube 344, so as to determine whether the oxygen in the sealed cavity between the arc shell 311 and the sealing tube 32 is emptied. The specific model of the gas detection probe 34 is not limited. Since the gas detection probe 34 is widely used in the prior art, the specific structure will not be repeated. The specific structure of the clamp 354 is not limited. The clamp 354 can be an elastic clamp or a limit clamp controlled by a screw.

[0050] Working principle: first, the control display 8 is used to control the first electric telescopic rod 315 to move the arc shell 311 out of the injection port 9. At this time, the first sealing plate 312 seals the injection port 9 from the inside to prevent external air from entering the analysis chamber 2. The biological material sample to be tested is placed in the sample placing dish 351, and the clamping member 354 is used to fix the biological material sample to be tested. The control display 8 is used to control the second electric telescopic rod 333 to move the third bevel gear 3321 to a position in transmission connection with the first bevel gear 317. Since the second key bar 3324 is located in the accommodating cavity 347 at this time, the second transmission tooth is disengaged from the tooth groove 353. Therefore, when the driving motor 3311 controls the second central tube 332 to rotate through the transmission tube 3312, the second limiting groove, and the first key bar 3323, the rotating second central tube 332 will only control the sealing tube 32 to rotate 180 degrees through the third bevel gear 3321 and the first bevel gear 317, so that the access port 321 is located in the arc shell 311.

[0051] The micro air pump 41 is turned on by controlling the control display 8. The micro air pump 41 discharges the nitrogen in the nitrogen tank 334 into the sealed cavity between the arc shell 311 and the sealing tube 32 through the flexible tube 3342 and the second center tube 332, and is used to discharge the air in the sealed cavity to the outside through the one-way valve 346. The gas detection probe 343 is used to monitor the gas composition passing through the fourth center tube 344. When the control display 8 shows that the gas composition monitored by the gas detection probe 343 does not contain oxygen or only has nitrogen, the micro air pump 41 is controlled to be turned off. The control display 8 is used to control The first electric telescopic rod 315 is used to move the arc-shaped shell 311 into the injection port 9. The second sealing plate 313 is used to seal the injection port 9 from the outside. The micro air pump 41 is controlled to start again by the control display 8. The nitrogen in the sealed cavity is re-absorbed into the nitrogen tank 334 by the suction function of the micro air pump 41. Finally, the driving motor 3311 is used to control the sealing tube 32 to rotate 180 degrees again, so that the access port 321 is located outside the arc-shaped shell 311. At this time, the biological material sample to be tested is completely exposed to the analysis cavity 2, so that it is convenient to use the energy analyzer 4 for detection;

[0052] When the surface of the biomaterial sample to be tested is uneven or irregular in shape, the control display 8 is used to control the second electric telescopic rod 333 to move the second key bar 3324 to the position of the first key slot 342, and at this time the second transmission gear 3322 is located in a position in transmission connection with the tooth slot 353, and when the second central tube 332 is controlled to rotate by the driving motor 3311, the rotating second central tube 332 drives the rotating frame 34, the sample placement part 35 and the biomaterial sample to be tested to rotate between -20 degrees and 20 degrees with the third central tube 341 as the axis through the second key bar 3324 and the first key slot 342, so as to facilitate the energy analyzer 4 to detect different positions on the surface of the biomaterial sample;

[0053] When the control display 8 is used to control the second electric telescopic rod 333 to move the second key bar 3324 into the accommodating chamber 347, and the second transmission gear 3322 is located in a position for transmission connection with the tooth groove 353, when the driving motor 3311 is used to control the rotation of the second center tube 332, the rotating second center tube 332 drives the bracket 352 and the sample dish 351 to move in the limit frame 345 through the second transmission gear 3322 and the tooth groove 353, so that the detection distance between the sample and the energy analyzer 4 can be adjusted according to the volume of the biological material sample.

[0054] In summary, the present application utilizes the structural design of the cooperation between the telescopic component 31, the sealing tube 32, the driving module 33, the rotating frame 34 and the sample placement part 35 in the sample introduction mechanism 3. (1) On the one hand, the sealing tube 32 can be automatically controlled to seal the biological material sample to be tested after the sample is placed, and the purpose of exhausting oxygen is achieved by discharging nitrogen between the sealing tube 32 and the arc shell 311, thereby preventing the biological material sample to be tested from oxidizing before entering the analysis chamber 2. On the other hand, the nitrogen can be extracted and the sealing tube 32 can be automatically opened after the biological material sample to be tested enters the analysis chamber 2, thereby facilitating the detection of the biological material sample to be tested by using the energy analyzer 4. (2) When the surface of the biomaterial sample to be tested is uneven or irregular in shape, the driving module 33 is used to control the biomaterial sample to be tested to rotate between -20 degrees and 20 degrees with the third central tube 341 as the axis, so that the energy analyzer 4 can detect different positions on the surface of the biomaterial sample; the driving module 33 is used to control the movement of the biomaterial sample to be tested and the sample dish 351 in the rotating frame 34, so that the detection distance between the biomaterial sample and the energy analyzer 4 can be automatically adjusted according to the volume of the biomaterial sample, which has the characteristics of easy adjustment and improved accuracy of the detection result.
