Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0024] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: a drug sampling device for drug analysis, including a sampling tube 1. A slideway 4 is provided on the outer wall of one side of the sampling tube 1. A sampling mechanism 5 is provided on the sampling tube 1, and an auxiliary mechanism 6 is provided on the sampling mechanism 5. The sampling mechanism 5 includes a ring column 51. The ring column 51 is slidably connected to the inner wall of the top of the sampling tube 1. A thread groove 53 is provided on the inner wall of the top of the ring column 51. A threaded column 54 is threadedly connected to the inner wall of the side surface of the thread groove 53. By setting the threaded column 54 to cooperate with the suction cup 55, one end of the threaded column 54 close to the ring column 51 is fixedly connected to the suction cup 55. By setting the suction cup 55 to extract and sample the drug and squeeze it out, the end of the threaded column 54 far from the suction cup 55 is fixedly connected to an adjusting disk 56. A scale plate 57 is fixedly connected to the outer wall of one side of the ring column 51, which is convenient for observing the scale of the inhaled and discharged drugs and preventing the problem of too much or too little drug sampling.

[0025] Refer to Figures 2 - 3, a sponge sealing cover 52 is fixedly connected to the bottom outer wall of the annular column 51. The sponge sealing cover 52 is slidably connected to the side inner wall of the sampling tube 1. A threaded groove 53 penetrates through one side inner wall of the sponge sealing cover 52. A suction cup 55 is slidably connected to the side inner wall of the sampling tube 1. A plurality of grooves are formed on the side outer wall of the adjusting disc 56. By providing the grooves, the problem of slipping off the hand when rotating the adjusting disc 56 is reduced. A scale plate 57 is slidably connected to the two side inner walls of the slideway 4. Transparent glass plates 58 are fixedly connected to the two side inner walls of the scale plate 57. By providing the transparent glass plates 58, it is convenient for personnel to observe the drug sampling situation inside the sampling tube in real time. An installation groove 2 is formed on the bottom inner wall of the sampling tube 1. A sampling head 3 is threadedly connected to the side inner wall of the installation groove 2.

[0026] Refer to Figures 3 - 4 , the auxiliary mechanism 6 includes a chute 60. The chute 60 is formed on one side outer wall of the scale plate 57. A dial 61 is slidably connected to one side inner wall of the chute 60. By providing the dial 61, it is convenient for personnel to operate. An arc-shaped block 62 is fixedly connected to one side outer wall of the dial 61. By providing the arc-shaped block 62, the scale plate 57 is clamped and fixed on the slideway 4 and separated. A small spring 63 is fixedly connected to the side outer wall of the dial 61 away from the arc-shaped block 62. By providing the small spring 63, a continuous thrust is generated on the dial 61. Frosted pads are fixedly connected to the two side outer walls of the dial 61. The arc-shaped block 62 penetrates through one side inner wall of the scale plate 57 and extends to the side outer wall of the scale plate 57. The arc-shaped block 62 is clamped on one side inner wall of the slideway 4. One end of the small spring 63 away from the dial 61 is fixedly connected to one side inner wall of the scale plate 57.

[0027] Working principle: By rotating the adjusting disc 56, the threaded column 54 rotates. Under the threaded action of the threaded column 54 in the threaded groove 53, it moves upward to drive the suction cup 55 to move. The suction cup 55 moves to suck the drug outside the sampling head 3 into the sampling tube 1. According to the scale plate 57 and the transparent glass plates 58, the inhaled drug dose and the required discharged dose are observed. At the same time, during long-term use, by pulling the dial 61 to squeeze the small spring 63, and at the same time, the movement of the dial 61 drives the arc-shaped block 62 to move. The arc-shaped block 62 moves away from the slideway 4. Subsequently, the annular column 51 is lifted to be separated from the sampling tube 1, so that the components of the sampling mechanism 5 are separated from the sampling tube 1 for convenient cleaning and maintenance.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
