[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figs. 1 to 3 This utility model provides an embodiment of a liquid sampler for a material analysis and testing instrument with a splash-proof baffle, comprising a pressure tube 1, a rubber head 2 slidably connected to the bottom of the pressure tube 1 for temporarily storing the extracted liquid reagent, a protective shell 3 fixedly connected to the outside of the pressure tube 1, a hinge 4 fixedly connected to the left side of the protective shell 3, and a shield 5 fixedly connected to the left side of the hinge 4. The main body of the extractor has a piston head 6 slidably connected to the inside of the pressure tube 1 for generating negative pressure, a piston rod 7 fixedly connected to the top of the piston head 6, a lever 8 fixedly connected to the top of the piston rod 7, and a resistance fixing piece 9 fixedly connected to the outside of the lever 8 to fix the position of the lever 8.
[0027] Reference Fig. 1 , Fig. 2 The shield 5 has a U-shaped groove to provide space for the extractor. The shield 5 has a U-shaped curved structure, which can better protect personnel and save space compared to a straight one. The shield 5 is rotatably connected to the left side of the protective shell 3 by the hinge 4. The shield 5 is made of transparent polycarbonate (PC) material, which has the advantages of corrosion resistance, high transparency and high strength.
[0028] Reference Fig. 3 The resistance fixing plate 9 is slidably connected to the inside of the air pressure pipe 1, and is connected in series with the piston head 6, piston rod 7 and paddle 8. Moving the paddle 8 up and down will drive the piston head 6 to achieve the operation of suction and ejection.
[0029] Compared with some existing devices, the above-mentioned device allows for more precise manual adjustment of the inhalation and spray volume, is more convenient to operate with one hand, and the added baffle improves safety and reduces the harm of the reagent to personnel.
[0030] Working principle: Rotate the shield 5, which is parallel to the sampler, to be perpendicular to the protective shell 3, and hold the sampler so that the field of view is behind the shield 5;
[0031] The piston head 6 moves up and down within the pneumatic tube 1 by pushing the lever 8, creating a negative pressure within the pneumatic tube 6. This draws the liquid sample into the nozzle 2, where it passes through the anti-splash baffle. When there is a possibility of liquid splashing, the shield 5 can block the liquid, preventing it from splashing out and ensuring the safety of the sampling process and the integrity of the sample.
[0032] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
