as shown in fig. 1 and 2, in embodiment 1 of the present invention, a pipe joint structure for connecting and sealing a dust cup 1 and an air inlet pipe 4 is provided.
The embodiment comprises a dust cup 1, a pipe connector 2, an air inlet pipe 4, a first sealing structure and a second sealing structure. The dust cup 1 is provided with an air inlet 11; the pipe connector 2 is arranged at an air inlet 11 of the dust collector; the air inlet pipe 4 is inserted on the pipe connector 2 and is communicated with the air inlet 11 through the pipe connector 2; the air inlet pipe 4 is clamped on the pipe joint piece 2 through a clamping structure 6; the first sealing structure is arranged at the joint of the pipe connector 2 and the air outlet and is suitable for sealing the interface of the dust cup 1 and the pipe connector 2; the second sealing structure is arranged at the joint of the pipe joint part 2 and the air inlet pipe 4 and is suitable for sealing the joint of the air inlet pipe 4 and the pipe joint part 2. Through the effect of first seal structure and second seal structure, can make the structure that air-supply line 4 utilized pipe connector 2 to install on dirt cup 1 have sealing performance, avoid taking place the leakproofness problem at joint state air-supply line 4 and dirt cup 1.
Specifically, the clamping structure 6 comprises a hook arranged at the insertion end of the air inlet pipe 4 and a clamping groove arranged on the pipe joint member 2, and the air inlet pipe 4 can be hooked on the clamping groove after being inserted into the pipe joint member 2. A spring is further arranged between the hook and the air inlet pipe 4, the hook and the clamping groove are always kept in a clamping state through the spring, a button is further arranged on the hook, and the spring can be compressed through pressing the button to enable the hook and the clamping groove to be in a clamping state.
As a specific embodiment of the first sealing structure, the first sealing structure comprises a first tubular section 12 fixedly arranged outside an air inlet 11 on the dust cup 1, and a flange 13 is formed in a cavity of the first tubular section 12 by extending the edge opening of the air inlet 11; a second tubular section 21 arranged on the pipe joint 2 and extending into the first tubular section 12, the second tubular section 21 having a gap between the outer wall and the inner wall of the first tubular section 12; a first seal ring 3, wherein a circumferential seal part 31 and an end face seal part 32 are arranged on the first seal ring 3; the circumferential sealing part 31 is cylindrical, is filled in a gap between the outer wall of the second tubular section 21 and the inner wall of the first tubular section 12, and is suitable for sealing the gap between the outer wall of the second tubular section 21 and the inner wall of the first tubular section 12; the end face seal 32 is annular and abuts between the flange 13 and the end face of the second tubular section 21. The advantage of the first sealing arrangement described above is that the circumferential seal 31 can seal and fill the side wall gap between the two tubular sections, while the end face seal 32 can press-fit seal the end face between the second tubular section 21 and the flange 13 of the dirt cup 1. This can thus effectively improve the sealing performance between the pipe joint 2 and the dirt cup 1 compared to a single face seal or circumferential seal.
In order to further optimize the structure of the first sealing ring 3, a first groove portion 33 is further provided on the first sealing ring 3, and the first groove portion 33 is adapted to wrap the flange 13. The first groove part 33 enables the positioning and the installation between the first sealing ring 3 and the dust cup 1 to be more convenient, and only the first groove part 33 is sleeved on the flange 13; on the other hand, the first groove portion 33 can prevent dust from entering the circumferential sealing portion 31 along the gaps on both sides of the first seal ring 3, and further prevent the circumferential sealing portion 31 from being sealed poorly due to the entering dust.
In a further development, the inner wall of the first sealing ring 3 at a position close to the inlet has a flow guiding surface 34, wherein the flow guiding surface 34 transitions smoothly from the interior of the first sealing ring 3 to the inner wall of the dirt cup 1. On the one hand, the sharp edges at the air inlet 11 of the dust cup 1 can be covered by the flow guide surface 34; on the other hand, the guide surface 34 can also have a guiding effect on the air flow entering the dirt cup 1, so that small vortex flows are avoided in the air flow.
In order to make the installation of the first sealing ring 3 more stable, a first anti-rotation structure is arranged between the first sealing ring 3 and the dust cup 1. This prevents the first sealing ring 3 from rotating after it has been mounted on the flange 13 of the dirt cup 1, and from premature wear damage due to the rotation of the sealing ring.
Specifically, the first rotation preventing structure comprises a pin 14, which is arranged on the inner wall around the air inlet 11 of the dust cup 1; a pin hole 35, which is provided on the first seal ring 3, is adapted to be fitted over the pin 14. The pin hole 35 of the first sealing ring 3 is sleeved on the pin 14 to realize the anti-rotation effect of the first sealing ring 3.
As a specific embodiment of the second sealing structure, the second sealing structure includes a third pipe-shaped section 41 disposed at one end of the air inlet pipe 4 inserted into the pipe joint 2; the second sealing ring 5 is arranged at the front end of the third tubular section 41 and is suitable for being abutted between the end face of the third tubular section 41 and the end face of the second tubular section 21 after the air inlet pipe 4 is clamped on the connecting piece 2. After the second sealing ring 5 is designed into the structure, the pressing sealing of the second sealing ring 5 can be realized by directly pushing the air inlet pipe 4, and the device is more suitable for the air inlet pipe 4 which needs frequent disassembly and assembly.
In order to further optimize the structure of the second sealing ring 5, a second groove 51 is provided on the second sealing ring 5, and the second groove 51 wraps the end face of the third tubular section 41.
In a further optimization of the second sealing structure, the outer diameter of the third tubular section 41 is smaller than the inner diameter of the second tubular section 21. This ensures that the second sealing ring 5 is not only subjected to the pressing force of the end face, but also to the shearing force when the air inlet pipe 4 and the pipe joint 2 are pressed against the second sealing ring 5. Thus, this can make the second seal ring 5 bear a larger sealing pressure, and the sealing effect thereof is improved.
In order to prevent rotation of the air inlet pipe 4, the pipe joint 2 and the dust cup 1, a second rotation preventing structure is arranged at the matching position of the air inlet pipe 4 and the pipe joint 2, and a third rotation preventing structure is arranged at the matching position of the pipe joint 2 and the dust cup 1. The second rotation preventing structure and the third rotation preventing structure specifically comprise: the cross sections of the first tubular section 12, the second tubular section 21 and the third tubular section 41 are all circular without a circular arc, and the anti-rotation function is realized through the cooperation of the special-shaped circular pipes.
