25 circuit is connected.
Fig. 5 is the structural representation of snap fastener in embodiment of the present utility model, and male joint is in female joint and engages
State；Fig. 6 is A-A face sectional view of the snap fastener in locking state in Fig. 5；And Fig. 7 is that snap fastener is in solution in Fig. 5
The A-A faces sectional view of lock status.
As shown in fig. 6, in locking state, fin 41 is fitted with the side 31 of latch segment 32, it is common to prevent latch segment 32
Travelled forward with respect to air entry 19, it is ensured that extension tube 25 and the strong bonded of air entry 19, will not easy disengagement.Additionally, extension
Joint body 22 is also appropriately designed with the cooperation taper of air entry 19 after pipe, it is ensured that joint body 22 will not be too deep after extension tube
Enter the inside of air entry 19, this point is identical with the design of common dust catcher interface.
In addition, the top edge of limit chamber 35 and rotating shaft 34 are in same plane, and put down with the axis of air entry 19
OK, when snap fastener is in locking state, limit rib 33 reaches the top edge of limit chamber 35, snap close piece 20 and air entry 19
Diameter parallel.
As shown in fig. 7, button 30 is pressed, the side 31 of latch segment 32 separates with fin 41, is now led toward rightabout
They are separated by drawing male joint 12 and female joint.
The application method of the dust catcher of the present embodiment is as follows：
Male joint 12 is loaded in the front end (namely female joint) of air entry 19 and toward propulsion inside dust collector host, it is female
The first rear end in contact with snap close piece 20 of fin 41 of joint front end, then along the slope extruding latch segment 32 of latch segment 32 so that lock
Tight block 32 is moved downward and compression spring 21, and until fin 41 crosses latch segment 32, spring 21 resets upwards, promotes latch segment 32
Into locking chamber 40, fin 41 is contacted with latch segment side 31, into locking state, while male joint 12 also reaches female joint
Internal depth capacity so that male joint 12 and the secure fit of air entry 19.
When male joint and female joint are in locking state, button 30 is pressed so that snap close piece 20 is downward around rotating shaft 34
Deflection, drives latch segment 32 to move downward and compression spring 21, until latch segment 32 and fin 41 are disengaged, now by public access
First 12, toward the direction movement away from air entry 19, can just extract male joint from the front end (female joint) of air entry 19 so that
Male joint 12 is disengaged with dust collector host.Now release button 30, the reset upwards of spring 21, drive latch segment 32 to reset,
Also just can next time be connected with dust catcher.
The effect of embodiment and effect
According to the snap fastener and dust catcher of the present embodiment, because male joint has the joint connected with vacuum cleaner attachment

Connect, the rear end of snap close piece is provided with limit rib and with bevelled latch segment, be provided with elastic component below the latch segment, and
Operation button is set between latch segment and rotating shaft, so, the snap fastener and dust catcher of the present embodiment can be by dust catchers
Air entry and vacuum cleaner attachment are connected and locked, and are pressed after button and can be contacted locking, both ensure that dust catcher was being used
During firm connection, in turn ensure that the convenience of dismounting.In addition, the inner wall smooth of the snap fastener of the present embodiment, does not have pin
Nail or like parts, will not care for hair, will not also produce extra noise.And, the snap fastener of the present embodiment need not
Manual operation buttons or other parts can just enter locking state, and coupling mechanism force is also enough to prevent vacuum cleaner attachment clear in push-and-pull
As long as being disengaged from dust catcher during sweeping, it is necessary to light pressure button and pulled out when unlocking, can just allow vacuum cleaner attachment with inhale
Dirt device main frame is disengaged, therefore, it is tight with annex that the snap fastener disclosed in the present embodiment had both realized suction port of suction cleaner
Coordinate, also have operation ease concurrently, more fully realize utility model target.
Above-mentioned implementation method is preferred case of the present utility model, is not intended to limit protection domain of the present utility model.
In the above-described embodiments, air entry is the air entry of dust collector host, but when dust collector host is assembled with extension
Guan Hou, need to such as assemble again, and air entry now is the air entry of extension tube.
In the above-described embodiments, vacuum cleaner attachment includes extension tube and suction nozzle, it is also possible to which, according to service condition, dust catcher is attached
Part only includes extension tube or suction nozzle.
In the above-described embodiments, button 30 is equal to button 30 to the half of the distance of rotating shaft 34 to the distance of latch segment 32,
In the utility model, button 30 to the distance of latch segment 32 might be less that button 30 to the half of the distance of rotating shaft 34, only
Technique effect of the present utility model can be realized.
