Minimum clearance between 24 and fan housing 1.That is, the first screw thread 242 and the second screw thread 631 are on the direction of travel T screwed
When screwing completely, there are prepsetting gap g between end cap 24 and fan housing 1, thickness of the second seal 7 in fastening direction is d, then
d≥g.In this way, the degree that screws of the sealing effect and the first screw thread 242 and the second screw thread 631 between end cap 24 and fan housing 1 has
Close, that is, screw that degree is about big, then the actual gap between end cap 24 and fan housing 1 is smaller, second seal 7 held it is tighter, into
And sealing effect is better.Moreover, when the thickness or other component of second seal 7 are there are during certain foozle, as long as
One screw thread 242 and the second screw thread 631 clamp second seal 7, then sealing effect will not decay because of the error.Especially
Ground, when prepsetting gap g is 0, the influence of the thickness d of first seal 7 to sealing effect can be ignored substantially.
During first state, it is upward can not only to provide first filter 23 for the first screw thread 242 and the cooperation clamping of the second screw thread 631
The pretightning force of fan housing 1, and it is further close between the space and outside being capable of providing between first filter 23 and motor cabinet 6
Envelope.The mounting structure of this motor cabinet and filter can be effectively prevented from causing during the vibrations of the motor when dust catcher works
Seal failure.Specifically, when dust catcher works, since motor is fixed on motor cabinet 6, so motor cabinet 6 can be in its radial direction
It is shaken on direction and axial direction.Due to will not between 1 and second threaded walls 63 of second end 232 and fan housing of first filter 23
It relatively moves, no matter whether first filter 23 itself deforms upon, the sealing at this will not fail due to vibrations.
When the second end 232 of first filter 23 is tightly connected with fan housing 1,24 upward second seal 7 of end cap.
The second protrusion 243 on end cap 24 squeezes second seal 7, since the second protrusion 243 has slightly pointed top, so can be with bigger
Pressure squeeze second seal 7, be even at least inserted partially into second seal 7, further enhance the effect of sealing.
Second embodiment
In the present embodiment, such as Figure 10, fan housing 1 further includes linkage portion 9, and linkage portion 9 includes being arranged on 1 upstream side of fan housing
Supporter 91 and the trigger member 92 hinged with 91 middle part of supporter, trigger member 92 is in through-hole 11 along its axial movement.Specifically,
Supporter 91 and trigger member 92 are rod-shaped.The first end 911 of supporter 91 is corresponding with the installation site of first filter 23,
The second end 912 of supporter 91 is corresponding with the installation site of the second filter 25.The first end 921 of trigger member 92 passes through pivot
93 are pivotally connected with the middle part of supporter 91, and trigger member on both sides of the middle is arranged with sliding slot 923.11 inner wall of through-hole corresponds to sliding slot 923
Symmetrical third protrusion 111 is extended in position to 11 center of through-hole, and third protrusion 111 coordinates with sliding slot 923, makes trigger member 92 big
Cause is moved axially along through-hole 11.When being fitted without first filter 23 and the second filter 25, under gravity, linkage
Portion 9 declines, and the second end 922 of trigger member 92 is detached from the contact of microswitch or is contacted in not exerting a force, so microswitch without
Method is triggered, then the control device judgement filter of dust catcher is not installed in place all, dust catcher is not allowed to start.Such as figure
11, when only install first filter 23 and the second filter 25 is not installed, the first end 911 of supporter 91 is due to first filter
23 effects for applying upward power F1 are lifted, however the second end 912 of first filter 23 declines due to not stressing, and entirely supports
Lever 91 is only rotated without around pivot 93 makes the whole apparent rising of linkage portion 9, therefore can not touch the contact of microswitch or hold
Continuous to exert a force to it, and then microswitch be triggered, then the control device judgement filter of dust catcher is not installed to all
Position, does not allow dust catcher to start.Situation when only installing the second filter 25 and do not install first filter 23 repeats no more.
Such as Figure 12, when all installations of 23 and second filter of first filter 25, the first end 911 of supporter 91 is due to the first mistake
The effect that filter 23 applies upward power F1 is lifted, and the second end 912 of supporter 91 is upward since the second filter 25 applies
The effect of power F2 is lifted, and then 9 entirety of linkage portion is lifted, and the contact of the touching microswitch of second end 922 of trigger member 92 is simultaneously right
It persistently exerts a force, and the control device judgement filter of dust catcher is all installed in place, and dust catcher is allowed to start.
