[0040] The present invention also provides a method for using a high-stability interconnected vacuum device, comprising the following specific steps:

[0041] Step 1: When the flow of the vacuum pump needs to be adjusted, the handle can be turned to drive the rotating ring on the rotating rod to rotate, so that the indicator plate under the elastic force of the third compression spring gradually moves along the inclined surface of the bottom end of the rotating ring, so that the baffle plate located above is displaced accordingly, and the gear is driven to rotate through the rack on the connecting rod, so that the baffle plate at the bottom can be relatively displaced under the movement of another group of connecting rods and racks, so that the size of the air inlet ports of multiple vacuum pumps can be adjusted;

[0044] Technical effects and advantages of the present invention:

[0045] (1) The present invention utilizes a configuration in which a rotary extrusion mechanism, a rotating ring, and a flow regulating mechanism cooperate with each other, so that when the vacuum pump is in use, the rotary extrusion mechanism can drive the rotating ring to rotate, so that the flow regulating mechanism can adjust the flow rate at the air inlet end of the vacuum pump. At the same time, when the filter plate is disassembled, the rotating ring no longer squeezes the flow regulating mechanism, so that the air inlet end of the vacuum pump can be completely closed by itself. Therefore, when the filter plate is disassembled and cleaned, no dust can enter the interior of the vacuum pump, which effectively prolongs the service life of the vacuum pump and facilitates use.

[0046] (2) The present invention utilizes a configuration in which a rotating rod, a sealing ring, an extrusion assembly and a rotating assembly are coordinated. The rotating rod can drive the rotating ring to adjust the flow rate of the vacuum pump inlet end, and the handle can be pulled upward, so that the clamping block can be clamped with the clamping hole, so that the sealing cover can be driven to rotate by the handle, and the sealing cover can be removed for easy use;

[0047] (3) The present invention utilizes a setting method in which a baffle, an indicator plate, an elastic component and a synchronization component are coordinated. The setting of the baffle can not only adjust the size of the air inlet port of the vacuum pump when the rotating ring rotates, but also completely block the air inlet port of the vacuum pump when the sealing cover is removed to clean and replace the filter plate, thereby effectively preventing dust from entering the interior of the vacuum pump, extending the service life of the vacuum pump, and facilitating use.

[0063] Furthermore, a mounting bracket 8 is fixedly connected to the inner wall of the filter box 1, and the filter plate 4 is slidably and interlacedly connected with the inner cavity of the mounting bracket 8.

The second compression spring 545 is always in a compressed state, so that the extrusion plate 544 can provide a stable downward elastic force to the sliding rod 541, so that the clamping block 543 is always inside the annular groove and does not intersect with the clamping hole. At this time, the rotating ring 6 on the rotating rod 51 can be driven to rotate by the handle 542. When the sealing cover 3 needs to be disassembled, the handle 542 can be pulled upward so that the sliding rod 541 can pull the clamping block 543 upward, so that the clamping block 543 can be clamped with the clamping hole.

At this time, without any external force, the baffle 71 can completely block the air inlet port of the vacuum pump 2, thereby preventing dust and impurities from entering the air inlet port of the vacuum pump 2 when the filter plate 4 is removed, and preventing dust and impurities from entering the interior of the vacuum pump 2 when the vacuum pump 2 is started again, thereby extending the service life of the vacuum pump 2.

A high stability interconnected vacuum device according to claim 5, characterized in that: The bottom end of the filter box (1) is threadedly connected to a support leg (10), and an observation window (11) is embedded in the outer wall of the filter box (1). The observation window (11) is made of a transparent material and is provided with a scale.

7. The method for using a high-stability interconnected vacuum device according to claim 6, characterized in that: The specific usage steps are as follows: Step 1: When the flow rate of the vacuum pump (2) needs to be adjusted, the handle (542) can be rotated so that the handle (542) drives the rotating ring (6) on the rotating rod (51) to rotate, so that the indicator plate (72) under the elastic force of the third compression spring (733) gradually moves along the inclined surface at the bottom end of the rotating ring (6), so that the baffle plate (71) located above is displaced accordingly, and the gear (742) is driven to rotate through the rack (744) on the connecting rod (743), so that the baffle plate (71) located at the bottom can be relatively displaced under the movement of another group of connecting rods (743) and racks (744), so that the sizes of the air inlet ports of multiple vacuum pumps (2) can be adjusted synchronously; Step 2: When the filter plate (4) needs to be disassembled and replaced, the handle (542) can be pulled upwards so that the sliding rod (541) can overcome the elastic force of the second compression spring (545), and the clamping block (543) can be pulled upwards so that the clamping block (543) can be clamped with the clamping hole. At this time, the handle (542) can be turned to drive the sealing cover (3) to rotate, and the sealing cover (3) can be removed. At the same time, the rotating ring (6) no longer limits the baffle (71) through the indicator plate (72). In the absence of any external force, the baffle (71) can completely cover the air inlet port of the vacuum pump (2) under the elastic force of the third compression spring (733); Step 3: After the sealing cover (3) is removed, the sealing gasket (532) no longer presses the filter plate (4), so that the groove of the filter plate (4) is exposed. The staff can insert their hands into the groove and lift the filter plate (4) from the inside of the mounting frame (8) and replace it with a new filter plate (4).
