[0024] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0025] As attached Figure 1 and Figure 8 As shown, a vacuum pumping device for packaging Pleurotus eryngii includes a vacuum main unit 1, a first air pipe 2, a connecting piece 3 and an air bag 5.

[0026] As attached Figure 1 and Figure 2 As shown, mounting holes 12 are penetrated on both sides of the bottom of the vacuum chamber 11 of the vacuum main unit 1, and the first air pipe 2 is installed in the mounting holes 12. Specifically, the lower end of the first air pipe 2 penetrates the mounting hole 12 and is threadedly connected with the first nut 23. Since the pipe wall of the pipe mouth at the upper end of the first air pipe 2 protrudes outward to form a clamping ring 21, and the diameter of the clamping ring 21 is larger than the diameter of the mounting hole 12, the first nut 23 can lock the first air pipe 2 in the mounting hole 12, thereby completing the installation of the first air pipe 2.

[0027] It is worth mentioning that Figures 2 to 4 As shown, the two first air pipes 2 are provided with a connecting piece 3, and the two connecting pieces 3 are respectively arranged on the two first air pipes 2. Specifically, the upper surface of the connecting piece 3 is provided with an inwardly concave connecting groove 31, and the bottom of the connecting groove 31 is penetrated with a connecting hole, and the diameter of the connecting hole is smaller than the diameter of the clamping ring 21. When installing the first air pipe 2, the lower end of the first air pipe 2 is sequentially penetrated through the connecting hole of the connecting piece 3 and the mounting hole 12 of the vacuum chamber 11, and then the first air pipe 2 and the connecting piece 3 are locked in the mounting hole 12 through the first nut 23. During the process, the clamping ring 21 is placed in the connecting groove 31, and the connecting piece 3 is sleeved on the outside of the first air pipe 2 to ensure the smooth subsequent assembly. And a first gasket 22 is provided between the first nut 23 and the clamping ring 21. The first gasket 22 is made of elastic material, specifically rubber or silicone support, with good sealing and strong anti-aging performance. After the first air pipe 2 is inserted into the mounting hole 12 , the first gasket 22 is firstly put on the outside of the first air pipe 2 , and then the first nut 23 and the first air pipe 2 are tightened. The first gasket 22 can play a sealing role to prevent the vacuum chamber 11 from leaking due to the gap between the first air pipe 2 and the mounting hole 12 .

[0028] As attached Figures 4 to 8As shown, there are two airbags 5, and the two airbags 5 are detachably connected to the connector 3. Specifically, a connector 52 is provided at the lower end of the second air pipe 51 of the airbag 5, and an external thread is provided on the outer side of the connector 52, and an internal thread is provided on the groove wall of the connecting groove 31 of the connector 3. When assembling the airbag 5 and the connector 3, the airbag 5 is rotated, and the connector 52 is screwed into the connecting groove 31. The airbag 5 is tightened in the connecting groove 31 of the connector 3 by using the thread engagement force between the connector 52 and the connecting groove 31. At this time, the second air pipe 51 is connected with the first air pipe 2, wherein the lower end of the first air pipe 2 is provided with a fourth air pipe 4, and the fourth air pipe 4 is connected to the electromagnetic valve. When the packaging bag of the pleurotus eryngii is sealed after vacuuming, the electromagnetic valve is controlled to make the gas pass through the fourth air pipe 4, the first air pipe 2 and the second air pipe 51 in sequence and then enter the airbag 5. At this time, the airbag 5 is inflated, so that the heat sealing press frame is lifted up and the bag mouth is pressed tightly to prepare for subsequent heat sealing.

[0029] In addition, as attached Figure 3 , Figure 6 and Figure 7 As shown, the bottom of the connecting groove 31 is provided with a second gasket 32, which is made of elastic material, specifically rubber or silicone, and has good sealing and anti-aging properties. When the airbag 5 is screwed into the connecting groove 31 of the connector 3, the connector 52 presses the second gasket 32 ​​against the bottom of the connecting groove 31, and the second gasket 32 ​​is used to seal and prevent air leakage at the connection between the second air pipe 51 and the first air pipe 2. In addition, as shown in the attached Figure 6 and Figure 7 As shown, the lower end of the second air pipe 51 is connected to the third air pipe 53. When the second air pipe 51 is connected to the first air pipe 2, the third air pipe 53 is inserted into the first air pipe 2. The setting of the third air pipe 53 can facilitate the connection and positioning between the second air pipe 51 and the first air pipe 2.

[0030] In summary, when installing the utility model, the lower end of the first air pipe 2 is sequentially passed through the connection hole of the connector 3 and the mounting hole 12 of the vacuum chamber 11, and then the first air pipe 2 and the connector 3 are locked in the mounting hole 12 by the first nut 23. During the process, the snap ring 21 is placed in the connection groove 31, and the connector 3 is sleeved on the outside of the first air pipe 2, and then the airbag 5 is rotated to screw the connector 52 into the connection groove 31. The threaded engagement force between the connector 52 and the connection groove 31 is used to tighten the airbag 5 in the connection groove 31 of the connector 3. At this time, the second air pipe 51 is connected with the first air pipe 2, so that the airbag 5 is quickly installed and fixed in the vacuum chamber 11 of the vacuum mainframe 1 for use. When the airbag 5 needs to be maintained, it is only necessary to rotate the airbag 5 to separate the connector 52 from the connector 3, and the airbag 5 can be removed for maintenance. There is no need to disassemble the vacuum mainframe 1 during the whole process, so that the airbag is easy to disassemble and maintain.

[0031] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
