[0030] Please see Figures 1-7This utility model provides a technical solution:

[0031] A quick-assembly type clean bench includes a bench frame 1, a ventilation assembly 2, and a ventilation pipe 3. An installation assembly 4 is installed inside the ventilation assembly 2. A ventilation control assembly 5 is fixedly connected to the upper end of the installation assembly 4. The installation assembly 4 includes an annular plate 41. A first ventilation channel 42, a second ventilation channel 43, a first fixing groove 44, and a second fixing groove 46 are opened inside the annular plate 41. A first rubber sealing ring 45 is fixedly connected to the inner side of both the first fixing groove 44 and the second fixing groove 46. An extension pipe 47 is fixedly connected to the top of the annular plate 41. A silicone duckbill valve 48 is fixedly connected to the inner side of the extension pipe 47. The ventilation control assembly 5 includes a fixed cylinder 51. A through hole 52 and a threaded hole 54 are opened inside the fixed cylinder 51. A second rubber sealing ring 53 is fixedly connected to the lower end of the threaded hole 54. The inner side of the threaded hole 54 is spirally fitted to the outer side of the threaded post 55. An operating handle 56 is fixedly connected to the top of the threaded post 55. The bottom end of the fixed cylinder 51 is fixedly connected to the top of the annular plate 41 near the second ventilation channel 43.

[0032] As a further implementation of this solution, the ventilation component 2 includes an air box 21. The bottom end of the air box 21 is fixedly connected to the top end of the workbench frame 1. A central slot 22 is provided inside the air box 21, and a connecting port 23 is provided at the bottom end of the air box 21. Through the above settings, a foundation is provided for the efficient operation of the clean workbench, ensuring that the airflow can smoothly enter the work area, thereby maintaining a high cleanliness environment inside the workbench.

[0033] As a further implementation of this solution, an external tube 24 is fixedly connected to the upper end of the bellows 21. An external groove 25 is provided on the inner side of the external tube 24, and the external groove 25 penetrates the upper part of the external tube 24. A spring 26 is fixedly connected to the lower end of the external groove 25. Through the above-mentioned arrangement, key support and buffer functions are provided for the quick connection of the ventilation pipe 3. During the installation process, the elastic storage of the spring 26 can ensure the tightness of the connection and effectively prevent gas leakage. At the same time, when disassembling, its elastic restoring force can be used to achieve quick separation, which greatly improves the convenience of operation.

[0034] As a further implementation of this solution, the bottom end of the ventilation pipe 3 is fixedly connected to the top end of the annular plate 41. The ventilation pipe 3 is set between the extension pipe 47 and the fixed cylinder 51. The inner side of the ventilation pipe 3 is connected to the inner side of the annular plate 41. Through the above arrangement, it is ensured that the airflow can be efficiently transmitted between the ventilation system and the clean workbench.

[0035] As a further implementation of this solution, the inner and outer sides of the annular plate 41 are both fitted with the outer groove 25, the two first rubber sealing rings 45 are both fitted with the inner side of the outer groove 25, the bottom end of the annular plate 41 is fitted with the top end of the spring 26, and the extension tube 47 and the fixing cylinder 51 both extend out of the upper end of the bellows 21. Through the above settings, this tight fit design ensures the airtightness of the airflow channel and prevents gas from leaking from the connection. At the same time, the extension structure of the extension tube 47 and the fixing cylinder 51 provides convenience for operation, so that the installation and disassembly process does not require the intervention of external tools, significantly reducing labor intensity and improving work efficiency. The first ventilation channel 42 and the second ventilation channel 43 both penetrate the interior of the annular plate 41 in the vertical direction, and the first ventilation channel 42 is connected to the interior of the extension tube 47.

[0036] As a further implementation of this solution, the threaded hole 54, the through hole 52, and the second vent 43 are connected. The bottom end of the threaded post 55 is fitted with the top end of the second rubber sealing ring 53. The second rubber sealing ring 53 is sleeved on the outside of the through hole 52. Through the above settings, the ventilation pipe 3 can be quickly blocked and unblocked, enabling the device to quickly switch states during installation and disassembly, further improving the convenience and efficiency of operation. At the same time, this design also ensures the sealing of the connection and effectively prevents gas leakage.

[0037] Workflow: When quickly connecting the clean bench to the ventilation duct 3 of the centralized ventilation system, initially the ventilation duct 3 is fixed to the annular plate 41 with sealant. The threaded post 55 is installed inside the threaded hole 54, and the bottom end of the threaded post 55 is in contact with the top end of the second rubber sealing ring 53, thus sealing the through hole 52. Align the annular plate 41 with the external groove 25 and place the annular plate 41 inside the external groove 25. At this time, the bottom end of the annular plate 41 will be in contact with the upper end of the spring 26. Then, by operating the extension tube 47 and the fixing cylinder 51, press down to move the annular plate 41 downward. At this time, both first rubber sealing rings 45 are in contact with the inner side of the external groove 25. This prevents the gas at the lower end of the annular plate 41 from overflowing from the gap between the annular plate 41 and the outer cylinder 24. The gas at the lower end of the annular plate 41 will only enter the interior of the extension pipe 47 through the first vent 42 when the annular plate 41 moves downward, and then flow out through the silicone duckbill valve 48. The silicone duckbill valve 48 has the effect of unidirectional gas flow. At this time, the annular plate 41 is limited inside the outer groove 25, and it is difficult to overflow the annular plate 41 from the outer groove 25. During the downward movement of the annular plate 41, the spring 26 will be squeezed, and the spring 26 will generate elastic storage. When the annular plate 41 can no longer move downward, the quick connection between the bellows 21 and the ventilation pipe 3 is completed.

[0038] When in use, the gas blown out by the ventilation pipe 3 will enter the concentrator 22 through the inside of the outer tube 24, and then be blown to the workbench of the workbench frame 1 through the connecting port 23. Alternatively, the ventilation pipe 3 can draw in air, and the air near the workbench will enter the inside of the outer tube 24 through the connecting port 23 and the concentrator 22, and then enter the inside of the ventilation pipe 3, thereby ensuring the safety of the experiment.

[0039] When separating the ventilation pipe 3 from the air box 21, the threaded column 55 is rotated by the operation. When the threaded column 55 is separated from the threaded hole 54, the through hole 52 and the threaded hole 54 are connected to the outside air. In this way, the air inside the external groove 25 will be connected to the outside air. Under the action of the spring 26, the annular plate 41 is pushed out from the external groove 25, thereby completing the dismantling of the ventilation pipe 3 from the air box 21.

[0040] Based on the above principles, when connecting the clean bench to the ventilation duct 3 of the centralized ventilation system, the traditional method of fixing with angle steel flanges has been changed. This installation and disassembly method is not only convenient and quick, without the need for external tools, but also ensures the sealing performance after installation, improves safety, and reduces the labor intensity of workers.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
