For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0028] Reference Figure 1-4This utility model provides an embodiment of a vacuum-type PP medicine cabinet, comprising a cabinet body 1, a rotatably connected closed cabinet door 2, a storage cavity 3 inside the cabinet body 1, a shelf 4 inside the storage cavity 3 for placing medicines, a vacuum chamber 5 inside the cabinet body 1 communicating with the storage cavity 3, multiple through holes at the bottom of the inner walls of the shelf 4 and the vacuum chamber 5, a fixing groove 6 at the top of the cabinet body 1, a vacuum pump 7 inside the fixing groove 6, a purification chamber 10 inside the cabinet body 1, and air pipes 8 and 9 connected to the vacuum chamber 5 and purification chamber 10 respectively. When the vacuum pump 7 is working, it can extract the gas in the storage cavity 3 and send it into the purification chamber 10, thus removing some of the gases emitted by the chemicals in the storage cavity 3. A purification rack 12 is provided inside the purification chamber 10. An adsorption purification layer 13 is provided, which is filled with activated carbon. Gas entering the purification chamber 10 can be adsorbed and purified by passing through the adsorption purification layer 13, thereby reducing the pollution of the surrounding area by the exhaust air and reducing the harm to the staff. An air outlet 14 is provided on one side of the inner wall of the purification chamber 10. A positioning recess 17 is provided on the top of the medicine cabinet 1 at the position corresponding to the purification chamber 10. A positioning cover 18 is nested in the positioning recess 17. A positioning mechanism is provided between the medicine cabinet 1 and the positioning cover 18. There are two positioning mechanisms, which are located on both sides of the top of the positioning cover 18. The positioning cover 18 can block and seal the top of the purification chamber 10, and can also be easily disassembled and opened, which facilitates the disassembly of the purification rack 12 and the cleaning or replacement of the adsorption purification layer 13.

[0029] A set of positioning blocks 11 are fixedly connected to the bottom of the inner wall of the purification chamber 10. The purification rack 12 is nested in the middle of the set of positioning blocks 11. This structure can accurately and stably position the purification rack 12 in the purification chamber 10, so that it can be stably positioned.

[0030] The air outlet 14 is provided with a filter screen 15 and a grille screen 16 from the inside to the outside. This structure can provide a shielding and protection effect for the air outlet 14. The filter screen 15 can prevent dust from entering the purification chamber 10 through the air outlet 14, while the grille screen 16 can enhance the protection.

[0031] A sealing block 19 is fixedly connected to the bottom of the positioning cover 18. The sealing block 19 and the purification chamber 10 are nested and sealed together. This structure can enhance the tightness of the positioning cover 18 during installation.

[0032] The top of the positioning cover plate 18 is provided with a handle groove 20, which facilitates the disassembly of the positioning cover plate 18.

[0033] The positioning mechanism includes a fixed shaft 22 fixed to the top of the medicine cabinet 1 and a positioning pin groove 25 set on the top of the positioning cover plate 18. A rotating block 21 is nested and rotatably connected to the fixed shaft 22. A fixed box 23 is fixedly connected to the rotating block 21. A positioning pin 24 is slidably connected inside the fixed box 23. An inner groove 26 is provided inside the fixed box 23. A moving block 27 and a spring 28 are respectively provided in the inner groove 26. The moving block 27 is nested and fixed to the outer surface of the positioning pin 24. A pull bracket 29 is fixedly connected to the top of the positioning pin 24. The positioning pin 24 and the positioning pin groove 25 are set with a plug-in fit. During operation, when the positioning cover plate 18 is engaged in the positioning... Within the recess 17, rotating the rotating block 21 causes the fixing box 23 to rotate to the top of the positioning cover 18, thus limiting its position. The elastic force of the spring 28 pushes the moving block 27 to the bottom of the inner groove 26. The moving block 27 can drive the positioning pin 24 to insert into the positioning pin groove 25, thereby completing the positioning work of the positioning mechanism. This achieves stable positioning and fixing of the positioning cover 18. When disassembling, pulling the pulling frame 29 causes the positioning pin 24 to leave the positioning pin groove 25. Rotating the rotating block 21 causes the fixing box 23 to leave the top of the positioning cover 18, thus opening the positioning mechanism and facilitating the disassembly of the positioning cover 18.

[0034] Working principle: When using the exhaust-type PP medicine cabinet, start the exhaust pump 7. The exhaust pump 7 drives the airflow. The airflow carries the chemical gases volatilized in the storage chamber 3 and enters the purification chamber 10 through the first air pipe 8 and the second air pipe 9 respectively. The gases are then purified by the adsorption purification layer 13 and finally discharged from the air outlet 14. This completes the exhaust work of the medicine cabinet 1. Open the positioning mechanism, pull the positioning cover 18 to make it move away from the positioning recess 17, and pull out the purification rack 12 to facilitate the cleaning or replacement of the purification rack 12.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
