Various aspects of the present utility model are described in this disclosure with reference to the accompanying drawings, which show many illustrative embodiments. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] As attached Figure 1 To be continued Figure 4 As shown: This embodiment provides a device for removing crystals introduced into a mass spectrometer, including a base 1. A first motor 2 is fixedly connected to the inner cavity of the base 1. A circular block 3 is fixedly connected to the output end of the first motor 2. A fixed plate 4 is fixedly connected to the top of the circular block 3. A second motor 5 is fixedly connected to the top of the fixed plate 4. A threaded rod 6 is fixedly connected to the output end of the second motor 5 through to the bottom of the fixed plate 4. The bottom end of the threaded rod 6 is rotatably connected to the surface of the circular block 3. A threaded block 7 is slidably connected to the surface of the threaded rod 6. A rotating table 8 is fixedly connected to one side of the threaded block 7. An electric telescopic rod 9 is rotatably connected to the surface of the rotating table 8. A housing 10 is fixedly connected to the output shaft of the electric telescopic rod 9. A third motor 11 is fixedly connected to the inner cavity of the housing 10. A turntable 12 is fixedly connected to the output end of the third motor 11. Three guide grooves 13 are opened on the surface of the turntable 12. Guide rods 14 are slidably connected to the inner cavities of the three guide grooves 13. A slider 15 is fixedly connected to one end of the guide rod 14. A scraper 16 is fixedly connected to one side of the slider 15.

[0021] Specifically, there are three scrapers 16 arranged in a circular array.

[0022] In this embodiment, the scraper 16 can effectively scrape the crystals inside the sample tube, and the ring array design of the three scrapers 16 can scrape the crystals more thoroughly, thereby improving the overall cleaning efficiency.

[0023] Specifically, the top of the base 1 is provided with an annular groove, and the bottom of the round block 3 is fixedly connected with four first limiting blocks 17, which are slidably connected in the inner cavity of the annular groove.

[0024] In this embodiment, the combination of the annular groove and the first limiting block 17 enhances stability, thereby ensuring that the circular block 3 is less likely to deviate or experience other unexpected situations during rotation, making the circular block 3 more stable and smooth during rotation.

[0025] Specifically, the inner cavity of the fixed plate 4 is fixedly connected to two limiting rods 18, and the threaded block 7 is slidably connected to the surface of the limiting rods 18. The two limiting rods 18 and the two ends of the threaded rod 6 are fixedly connected to the second limiting block 19.

[0026] In this embodiment, the use of the limiting rod 18 and the second limiting block 19 ensures that the threaded block 7 can smoothly rise and fall. The second limiting block 19 limits the maximum rising and falling distance of the threaded block 7, which plays an effective limiting role, thereby making the threaded block 7 more stable and accurate during operation.

[0027] Specifically, the surface of the housing 10 is provided with three sliding grooves, and the other side of the slider 15 is fixedly connected to a guide block 20, which is slidably connected to the inner cavity of the sliding groove.

[0028] In this embodiment, the second sliding groove and the guide block 20 work together to ensure that the second motor 5 can slide smoothly along the predetermined trajectory, thereby avoiding unnecessary deviation of the slider 15, effectively improving the scraping effect of the scraper 16 on the crystals, and enhancing the stability of the overall structure.

[0029] The working principle and usage process of this utility model are as follows: First, the user places the device on one side of the mass spectrometer and aligns the scraper 16 with the sample inlet tube of the mass spectrometer. Then, the rotating stage 8 is started, causing the scraper 16 to rotate and scrape the crystals inside the sample inlet tube. After the crystals are scraped off, for the difficult-to-scrape parts deep inside the sample inlet tube, the electric telescopic rod 9 is activated, causing the electric telescopic rod 9 to slowly move the scraper 16 deeper into the sample inlet tube. At this time, the scraper 16 can gradually scrape the crystals deep inside the sample inlet tube. To avoid damage to the sample inlet tube and the scraper 16, the user can activate the third motor 11 inside the housing 10. The third motor 11 drives the turntable 12 to rotate, and the surface of the turntable 12 is provided with guide grooves 13. By rotating the turntable 12, the guide groove 13 pushes the guide rod 14 to move within its cavity, thereby driving the slider 15 to move outward within the second sliding groove cavity. In this way, the slider 15 drives the scraper 16 to slowly scrape the crystals from the middle of the injection tube outward, which can adapt to injection tubes of different sizes and avoid damage to the injection tube. When facing injection tubes of different heights or orientations, the user can start the first motor 2 in the base 1, so that the first motor 2 drives the circular block 3 to rotate, thereby making the entire device rotate, ensuring effective scraping of injection tubes of different orientations. After starting the second motor 5, the threaded rod 6 will rotate, driving the threaded block 7 to rise and fall on the surface of the threaded rod 6, thereby realizing height adjustment, so as to scrape the crystals in injection tubes of different heights.

[0030] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0031] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
