DETAILED DESCRIPTION

[0018] 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.

[0019] like Figure 1 The laboratory aseptic workbench shown includes a workbench 1 and an equipment box 2. A transparent partition 3 surrounds the workbench 1 at the bottom of the equipment box 2. The left and right sides of the transparent partition 3 are sealed to the workbench 1, and operating windows 4 are provided on both the front and rear sides of the transparent partition 3. The equipment box 2 is conventionally equipped with ultraviolet lamps and an air outlet. The ultraviolet lamps irradiate the workbench 1 to sterilize it, and the air outlet forms an air wall to prevent external bacteria from entering during aseptic operation.

[0020] like Figure 2 As shown, a cross-section scraping assembly 5 is installed on the operating table 1. Racks 6 are installed on both the front and rear sides of the operating table 1, extending along the length of the operating table 1 and being lower than its surface. Drive gears 7, meshing with the racks 6, are installed at both ends of the scraping assembly 5. The two drive gears 7 are connected by a drive shaft 8, which is connected to a motor 9. The motor 9 drives the two drive gears 7 to rotate, thereby moving the scraping assembly 5 across the surface of the operating table 1.

[0021] like Figure 3 As shown, the scraping assembly 5 includes a housing 10, with the motor 9 mounted on the housing 10. The drive shaft 8 is rotatably mounted on one side inside the housing 10, and a scraping block 11 is mounted on the other side inside the housing 10. The scraping block 11 is made of absorbent material, such as cotton cloth, cotton, or sponge. A shallow groove is formed at the bottom of the housing 10 corresponding to the scraping block 11, and the scraping block 11 is fixed in the shallow groove. A wire slot 12 is formed above the shallow groove in the housing 10, and the wire slot 12 is connected to the scraping block 11 through the shallow groove. 75% alcohol is poured into the wire slot 12. After the scraping block 11 absorbs the alcohol, it wipes the alcohol onto the surface of the worktable 1 as the scraping assembly 5 moves.

[0022] In another implementation, such as Figure 4 As shown, the rack 6 is installed horizontally, and the top of the operating table 1 is provided with an extension plate 13 that covers the top of the rack 6. The drive gear 7 meshes on the rack 6, and the drive gear 7 is connected to the drive shaft 8 through a vertical shaft gear set 14. The outside of the vertical shaft gear set 14 is provided with a cover 15, and the cover 15 is fixedly connected to the housing 10 of the scraping assembly 5. This embodiment can hide the drive gear 7 and the rack 6, avoiding direct exposure to the outside.

[0023] likeFigure 1 and Figure 5 As shown, a square hole is provided on the left or right side of the transparent partition 3. A liquid injection component 16 is fitted into the square hole, and a liquid channel 17 is provided inside the liquid injection component 16. The liquid channel 17 has a pouring port 18 on the outside of the transparent partition 3 and a drain port 19 on the inside of the transparent partition 3. The pouring port 18 is higher than the drain port 19, making the liquid channel 17 inclined. When the scraping assembly 5 is moved to the left or right limit position of the operating table 1, the wire groove 12 is located directly below the drain port 19. When the wire groove 12 is aligned with the drain port 19, 75% alcohol can be poured in from outside the operating table 1 through the pouring port 18. The alcohol flows into the wire groove 12 along the liquid channel 17 and the drain port 19, eventually filling the scraping block 11 with alcohol.

[0024] The injection component 16 is provided with slots 20 at both the top and bottom ends and the left and right ends. The transparent partition 3 is fitted into the slots 20. A sealing gasket can be provided in the slots 20 to seal the gap between the transparent partition 3 and the injection component 16.

[0025] like Figure 1 and Figure 6 As shown, a waste discharge port 21 is provided at the left or right end of the operating table 1. The length of the rack 6 extends to the waste discharge port 21, allowing the scraping assembly 5 to move to the waste discharge port 21. A waste discharge channel 22 is provided below the waste discharge port 21, and the waste discharge channel 22 has an outlet on the side of the operating table 1. When the scraping assembly 5 moves toward the waste discharge port 21, it can push impurities and debris on the operating table 1 into the waste discharge port 21, thereby cleaning the operating table 1.

[0026] During use, 75% alcohol can be poured into the scraper block 11 through the injection fitting 16, or alcohol can be manually added to the groove opening 12 using a pipette. The initial position of the scraper assembly 5 is on the opposite side of the waste outlet 21 on the operating table 1. For example, if the waste outlet 21 is on the left side of the operating table 1, then the initial position of the scraper assembly 5 is on the right side of the operating table 1. Before using the operating table 1 or after completing the aseptic operation, start the motor 9 to move the scraper assembly 5 laterally along the surface of the operating table 1 from its initial position. During this process, the scraper block 11 will spread alcohol onto the surface of the operating table 1. When the scraper assembly 5 moves to the waste outlet 21, it can push impurities and debris on the surface of the operating table 1 into the waste outlet 21. If it is before the start of the aseptic operation, after the scraper assembly 5 has cleaned the operating table 1, the items to be used in the experiment can be placed on the operating table 1 in sequence, and then irradiated with ultraviolet light for 30 minutes before the experiment can be conducted.

[0027] It is obvious for those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, but that it can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and are not limiting in any way.
