[0023] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0024] Please refer to Figures 1-5 , the clean air workbench for laboratory use of the present invention includes a main frame 1 of the workbench. The main frame 1 of the workbench is the installation structure of the clean air workbench and is used for installing other structures. A table top 11 is arranged inside the main frame 1 of the workbench. The table top 11 is the main body of the clean air workbench, that is, experimental operations are carried out on the table top 11. Limit blocks 32 are arranged on both sides of the table top 11, and limit rails 34 are arranged on both sides inside the main frame 1 of the workbench. The limit blocks 32 are slidably connected to the limit rails 34. A threaded pipe 21 is arranged at the bottom inside the table top 11, and a threaded rod 23 is arranged at the bottom of the threaded pipe 21. That is, by rotating the threaded rod 23, the limit rails 34 on both sides limit the limit blocks 32, so that the table top 11 can be lifted and lowered, which is convenient for different people to use. The threaded rod 23 is threadedly connected to the threaded pipe 21. A motor 24 is arranged at the bottom inside the main frame 1 of the workbench, and the motor 24 is connected to the bottom of the threaded rod 23, that is, the motor 24 drives the threaded rod 23 to rotate.

[0025] On both sides of the bottom of the main workbench frame 1, there are storage cabinets 13. Above the storage cabinets 13, there are drawers 12. The drawers 12 and the storage cabinets 13 are used to store experimental items that are not often used and can be taken out when needed. Above the workbench surface 11, there is a placement board 3, which is used to place frequently used experimental supplies for convenient access. On both sides of the placement board 3, there are mounting strips 31. Above the limit rails 34, there are mounting rails 33. The mounting strips 31 are slidably connected to the mounting rails 33. That is, by sliding the mounting strips 31 on the mounting rails 33, the placement board 3 can be disassembled and assembled for easy cleaning. On the main workbench frame 1, there is a drain outlet 2. At the bottom of the drain outlet 2, there is a water receiving bottle 22. The inner side of the top of the water receiving bottle 22 is threadedly connected to the outer side of the bottom of the drain outlet 2. The water accidentally spilled during experiments on the workbench surface 11 is discharged through the drain outlet 2 and flows into the water receiving bottle 22 for storage. The sewage can be poured out by disassembling the water receiving bottle 22.

[0026] On the top of the main workbench frame 1, there is a top plate 14. The top plate 14 serves as the top mounting structure of the workbench. Inside the bottom of the top plate 14, there is a lighting lamp 4 for lighting to facilitate experimental operations at night. On one side of the lighting lamp 4, there is a gas purification groove 41, which is located in the front inside of the top plate 14, so as to effectively absorb gases. On the gas purification groove 41, there is a filter screen 42 to filter small impurities to prevent them from entering the gas purification groove 41. On the top of the gas purification groove 41, there is an exhaust pipe 43. On the top of the top plate 14, there is a wind box 45, which is a gas purification structure. Inside the wind box 45, there is a gas purification fan 5. On the top of the exhaust pipe 43, there is a connection port 44. That is, by sucking air with the gas purification fan 5 and connecting the connection port 44 to one side of the wind box 45, the exhaust pipe 43 drives the gas purification groove 41 to suck air, so as to absorb the gases on the workbench and achieve the effect of gas purification.

[0027] The working principle of the present utility model is as follows: Experimental operations are carried out on the tabletop 11. The motor 24 drives the threaded rod 23 to rotate, and the limiting rails 34 on both sides limit the limiting blocks 32, so that the tabletop 11 is lifted and lowered, facilitating the use by different people. The drawer 12 and the storage cabinet 13 are used to store experimental items that are not often used. The placement board 3 is used to place experimental supplies that are often used, facilitating taking and placing. The placement board 3 is disassembled by sliding the installation strip 31 on the installation rail 33, facilitating cleaning. The water left over from experiments on the tabletop 11 is discharged through the drain port 2 and flows into the water receiving bottle 22 for storage. The sewage is poured out by disassembling the water receiving bottle 22. Lighting is provided by the lighting lamp 4, facilitating experimental operations at night. The air purification fan 5 sucks air. One side of the air box 45 is connected through the connection port 44, so that the exhaust pipe 43 drives the air purification groove 41 to suck air, thereby absorbing the gas on the workbench and achieving the effect of air purification. Small impurities are filtered by the filter screen 42 to prevent them from entering the air purification groove 41.

[0028] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
