The working principle is that when the vacuum pump is used, the vacuum pump 1 is started, the adapter 2 is arranged on one side of the vacuum pump 1, the exhaust pipe 3 is arranged on one side of the adapter 2, the furnace body 5 is inserted into one side, away from the adapter 2, of the exhaust pipe 3, so that air in the furnace body 5 can be extracted through the exhaust pipe 3, and the air guide pipe 10 is arranged at the bottom of the adapter 2, so that the air can be discharged through the air guide pipe 10.

And because the filter screen 17 is fixedly connected to the bottom inside the air duct 10, the external dust can be blocked outside the air duct 10 at the moment, and the dust is prevented from entering the furnace body 5 through the air duct 10 to influence the welding quality.

Because the inside swing joint of air duct 10 has axis of rotation 11 again, the outer wall fixedly connected with impeller 12 of axis of rotation 11, so impeller 12 can drive axis of rotation 11 this moment and rotate, because the outer wall fixedly connected with drive gear 13 of axis of rotation 11, the bottom meshing of drive gear 13 is connected with driven gear 14, so drive gear 13 can drive driven gear 14 and rotate this moment, because the bottom fixedly connected with dwang 15 of driven gear 14, the bottom fixedly connected with knee lever 16 of dwang 15, so knee lever 16 can also rotate this moment, because the top of knee lever 16 and the bottom sliding connection of filter screen 17, so knee lever 16 can scrape off the remaining dust on the surface of filter screen 17 this moment, avoid the dust to block filter screen 17, influence the filter screen filter effect, thereby reached the automatic clear filter screen surface remaining dust and avoided the dust to get into the welding stove and improve the effect of welding quality.

Because the inside of fixed cover 4 has the screw thread with the screw thread looks adaptation of exhaust tube 3 outer wall again, one side threaded connection that adapter 2 was kept away from to exhaust tube 3 has fixed cover 4, so fixed cover 4 can be at the outer wall motion of exhaust tube 3 this moment, because the right side threaded connection of fixed cover 4 outer wall is in the inside of furnace body 5 again, and the inside of furnace body 5 has the screw thread with the outer wall looks adaptation of fixed cover 4, so fixed cover 4 can screw thread to the inner wall of furnace body 5 this moment, can make fixed cover 4 seal the spread groove between furnace body 5 and exhaust tube 3 through rotating fixed cover 4 this moment, avoid gas leakage.

Fixed cover 4 of reverse rotation, then extract furnace body 5 with exhaust tube 3, because the left side of chock plug 8 is equipped with four spinal branch vaulting poles 9, one side of chock plug 8 and the one end butt of exhaust tube 3 are kept away from to bracing piece 9, so the chock plug 8 is not receiving the holding power of exhaust tube 3 this moment, again because the inside fixedly connected with supporting spring 7 of fixed frame 6, one side fixedly connected with chock plug 8 of fixed frame 6 is kept away from to supporting spring 7, so chock plug 8 can move left this moment, again because the volume of chock plug 8 and the connecting groove looks adaptation of

furnace body

5 and 3 junction of exhaust tube, and chock plug 8 is right-hand right directly at this connecting groove, so the connecting groove of

furnace body

5 and 3 junction of exhaust tube can be plugged up to chock plug 8 this moment, outside air enters into the inside of vacuum welding stove when avoiding overhauing, thereby the strong maintenance process of device leakproofness has been reached and can not influence the effect of vacuum welding stove normal use.

In conclusion, according to the vacuum pumping mechanism with high sealing performance for the vacuum welding furnace, the filter screen 17 can block external dust to the outside of the air guide pipe 10, the impeller 12 is prevented from driving the rotating shaft 11 to rotate when the dust enters the furnace body 5 through the air guide pipe 10 for use, the rotating rod 15 is further enabled to drive the bent rod 16 to rotate, and at the moment, the bent rod 16 can scrape off the residual dust on the surface of the filter screen 17, so that the effect of automatically removing the residual dust on the surface of the filter screen to prevent the dust from entering the welding furnace and improve the welding quality is achieved.

Rotate fixed cover 4, extract furnace body 5 with exhaust tube 3, stopper 8 is not receiving the holding power of exhaust tube 3 this moment, and stopper 8 moves left under supporting spring 7's effect this moment, further makes stopper 8 plug up the spread groove of

furnace body

5 and 3 junctions of exhaust tube, and outside air enters into the inside of vacuum welding stove when avoiding overhauing to it can not influence the effect of vacuum welding stove normal use to have reached the strong maintenance process of device leakproofness.
