To sealing 31 and end face seal portion 32；The peripheral sealing section 31 is tubular, and filling is mounted on the outer wall of the second cast section 21
Inner wall in gap between the inner wall of the first cast section 12, suitable for outer wall and the first cast section 12 to the second cast section 21
Between gap be sealed；The end face seal portion 32 is annular, and is connected to the end face of flange 13 and the second cast section 21
Between.The advantages of above-mentioned first sealing structure, is that peripheral sealing section 31 can carry out sidewall spacers between two cast sections
Sealing filling, and end face seal portion 32 can be close to the pressing for carrying out end face between the second cast section 21 and the flange 13 of dirt cup 1
Envelope.Thus one, compared to single end face seal or circumferential seal, this measure can effectively improve pipe connecting piece 2 and dirt cup 1
Between sealing performance.
In order to advanced optimize the structure of the first sealing ring 3, the first groove portion 33 is additionally provided on first sealing ring 3,
First groove portion 33 is suitable for wrapping up flange 13.By the first groove portion 33, the first sealing ring 3 and dirt on the one hand can be made
Location and installation between cup 1 is more convenient, it is only necessary to which the first groove portion 33 is sleeved on flange 13；On the other hand, the first slot
Portion 33 can be avoided dust and enter at peripheral sealing section 31 along the gap of 3 two sides of the first sealing ring, and then avoid circumferential seal
Portion 31 generates poorly sealed due to entering dust.
In further optimization, first sealing ring 3 has guide face 34 on the inner wall of the position of import,
The guide face 34 is from inside the first sealing ring 3 to the interior walls be smooth transition of dirt cup 1.It can be covered by 34 one side of guide face
Sharp crest line at 1 air inlet 11 of dirt cup；On the other hand, guide face 34 can also generate guidance effect to the air-flow entered in dirt cup 1
Fruit avoids generating small-sized vortex in air-flow.
In order to keep the installation of the first sealing ring 3 more stable, first is provided between first sealing ring 3 and dirt cup 1
Anti-rotation structure.It rotates, is avoided due to close after on the flange 13 that this measure can prevent the first sealing ring 3 to be mounted in dirt cup 1
The rotation of seal and by premature wear-out failure.
Specifically, first anti-rotation structure includes pin 14, it is arranged on the inner wall around 1 air inlet 11 of dirt cup；Pin
Hole 35 is provided on the first sealing ring 3, suitable for being sleeved on pin 14.By the way that the pin hole 35 of the first sealing ring 3 is sleeved on column
The anti-rotation effect of the first sealing ring 3 is realized on pin 14.
As a kind of specific embodiment of second seals structure, the second seals structure includes third cast section 41,
One end that pipe connecting piece 2 is inserted on blast pipe 4 is set；Second sealing ring 5, is mounted on the front end of third cast section 41, and is suitable for
Blast pipe 4 is connected between the end face of third cast section 41 and the end face of the second cast section 21 after being clamped on pipe connecting piece 2.Passing through will
After second sealing ring 5 is designed to above structure, pushing directly on blast pipe 4 can be realized the pressing sealing of the second sealing ring 5, more
It is applicable to the blast pipe 4 frequently dismounted.
In order to advanced optimize the structure of the second sealing ring 5, it is provided with the second groove portion 51 on described time the second sealing ring 5,
Second groove portion 51 is wrapped on the end face of third cast section 41.
In the further optimization process of carry out to second seals structure, the outer diameter of the third cast section 41 is less than
The internal diameter of second cast section 21.This measure can guarantee blast pipe 4 and pipe connecting piece 2 when pressing the second sealing ring 5, and second is close
The not only pressure force by end face of seal 5, also suffers from shearing force.Thus, it is bigger that this measure can be such that the second sealing ring 5 bears
Sealed pressure improves its sealing effect.
