[0026] The heat dissipation shell 7 is provided to facilitate the installation of the motor 8. The inside of the liquid chromatograph body 1 can be cooled by starting the fan 19. The first transmission wheel 9 is rotated by starting the motor 8. The first transmission wheel 9 is rotated to rotate the second transmission wheel 11 through the belt 10. The first transmission wheel 9 rotates to move the threaded block 13 connected to the external thread of the screw rod 12. The threaded block 13 moves and moves the mounting plate 15 fixed to the outside of the connecting rod 14. The mounting plate 15 moves and moves the fan 19, thereby preventing the temperature in the liquid chromatograph from being too high and causing damage to the electrical components in the liquid chromatograph, and improving the heat dissipation efficiency. The guide ring 17 is connected to the outside of the fixing rod 16 through sliding, which plays a guiding role.
[0027] Reference Figure 4 and Figure 5 A fixing frame 21 is fixedly connected to the outside of the heat dissipation shell 7, and a filter plate 28 is slidably connected to the inside of the fixing frame 21. Mounting tubes 22 are fixedly connected to both sides of the outside of the heat dissipation shell 7, and a slider 23 is slidably connected to the inside of the mounting tube 22. A pull ring 24 is fixedly connected to the front side of the outside of the slider 23, and an insertion rod 26 is fixedly connected to the right side of the outside of the slider 23.

The pull ring 24 is pulled to move the plug rod 26 fixed on the right side of the outside of the slider 23 while squeezing the spring 25 fixed on the left side of the outside. Then, when the plug rod 26 is separated from the inside of the socket 27, the pull ring 24 is inserted into the limiting groove 29. Then, the filter plate 28 can be taken out for cleaning, so that the filter plate 28 installed inside the heat dissipation shell 7 can be easily disassembled and cleaned, and dust, dirt and other impurities can be effectively prevented from accumulating inside the heat dissipation shell 7, and air flow can be prevented from being obstructed, thereby improving the heat dissipation efficiency.

[0029] Reference Figure 1 and Figure 2 A solvent rack 2 is fixedly connected to the upper part of the liquid chromatograph body 1, a storage box 6 is fixedly connected to the left side of the outside of the liquid chromatograph body 1, a limiting ring 4 is fixedly connected to the inside of the solvent rack 2, a liquid storage bottle 5 is arranged inside the limiting ring 4, and a display screen 3 is installed on the front side of the outside of the liquid chromatograph body 1.
[0030] By setting up the solvent rack 2, it is convenient for experimenters to store and take out different kinds of solvents, so as to perform experimental operations more efficiently; by setting up the storage box 6, some commonly used tools, consumables or documents and other items can be neatly stored together, making the working area more tidy and orderly and reducing clutter; by setting up the limit ring 4, it plays a role in placing the liquid phase storage bottle 5, and the liquid phase storage bottle 5 can be used to store the solvents or reagents needed in the laboratory; by setting up the display screen 3, it is convenient for operators to intuitively view and operate the equipment, reducing the time required to move around the equipment and improving work efficiency.
[0031] Working principle: when the temperature inside the device body rises, the fan 19 is started, and the fan 19 rotates to generate wind to cool the inside of the device while starting the motor 8. The motor 8 rotates with the first transmission wheel 9 fixedly connected to the output end, and the first transmission wheel 9 rotates with the second transmission wheel 11 through the belt 10. When the first transmission wheel 9 rotates, it rotates with the internally fixed screw rod 12, and the screw rod 12 rotates with the threaded block 13 connected to the outside thread to move, and the threaded block 13 moves with the connecting rod 14 fixed to the outside to move, and the connecting rod 14 moves with the externally fixed mounting plate 15 to move, and the mounting plate 15 moves with the fan 19, so that the up and down movement of the fan 19 expands the heat dissipation area inside the liquid chromatograph, which can prevent the temperature inside the liquid chromatograph from being too high, causing damage to the electrical components in the liquid chromatograph, and improve the heat dissipation efficiency. Then, when the filter plate needs to be adjusted, When cleaning, the pull ring 24 is pulled to move the plug rod 26 fixedly connected to the right side of the outer side of the slider 23. When the slider 23 moves with the plug rod 26, the spring 25 fixedly connected to the left side of the outer side is squeezed, so that the spring 25 is deformed under the force, so that the plug rod 26 is separated from the inside of the insertion hole 27. Then, when the pull ring 24 moves to the limit groove 29, the pull ring 24 can be stuck into the inside of the limit groove 29 to prevent the plug rod 26 from rebounding. Then, the filter plate 28 can be taken out for cleaning. After cleaning, the filter plate 28 is inserted into the inside of the fixing frame 21, and then the pull ring 24 is removed from the inside of the limit groove 29. Under the reaction force of the spring 25, the plug rod 26 is inserted into the inside of the insertion hole 27, so that the filter plate 28 installed in the heat dissipation shell 7 can be easily disassembled and cleaned, which can effectively prevent dust, dirt and other impurities from accumulating inside the heat dissipation shell 7 and prevent air flow from being blocked, thereby improving the heat dissipation efficiency.
