Technical field

The present invention relates to dust catchers, in particular to a kind of flexible dirt cup of dust catcher.

Background technique

Dust catcher can be divided into vertical, horizontal and portable by structure.The working principle of dust catcher is driven using motor Blade high speed rotation generates air negative pressure in the shell of sealing, draws dust, with the improvement of living standards, portable Dust catcher starts the visual field for entering people on a large scale, it is easy to carry and with take with specific firmly get favorable comment.

Portable dust catcher easily exists simultaneously the problem of dust collecting space deficiency providing, and users often need to clear up Dirt cup, it is therefore desirable to expand dust collecting space in the case where not changing dust catcher volume, and then overcome its dust collecting space insufficient Problem.

Summary of the invention

In consideration of it, being expanded in dust catcher compared to the prior art the present invention provides a kind of flexible dirt cup of dust catcher Space is received in the storage of dirt cup, and hides storage when not in use and receive space, easy to carry.

For this purpose, the present invention provides a kind of flexible dirt cups of dust catcher, it is provided with cup body first, first end offers Cavity, and the second end of cup body has been removably installed dirt mouth, the first side wall of cavity offers location hole, and push-and-pull column is worn It is moved in cavity and along the length direction of cavity, the first end for pushing and pulling column is fixedly connected with limit disk, pushes and pulls column Side wall offers the first locating slot and the second locating slot, and the position of the position of the first locating slot and the second locating slot corresponds to location hole Position, limit switch is slidably mounted in cup body, and limit switch includes slip lid and elastomeric element, and elastomeric element is elastically mounted to The bottom of slip lid simultaneously passes through location hole under the effect of elasticity.

Further, mounting groove is offered in cup body, limit switch is set in mounting groove.

Further, slip lid is slidably mounted in mounting groove and slides along the length direction of mounting groove.

Further, location hole is located in mounting groove, and elastomeric element passes through location hole and holds out against in the first locating slot or the In two locating slots.

Further, elastomeric element includes spring and jacking block, and the first end of spring is fixedly connected on the lower surface of slip lid, And jacking block is fixedly connected with the second end of spring.

Further, jacking block passes through location hole and holds out against in the first locating slot or the second locating slot.

Further, jacking block is circular cone, and the first locating slot and the second locating slot are all cone tank.

Further, the second end for pushing and pulling column offers annular groove, is socketed with sealing ring in annular groove.

Further, the section of sealing ring is in the shape of the letter V.

Further, the first end of dirt mouth is connected in the second end of cup body, and the second end of dirt mouth is bolted in cup The second end of body.

A kind of flexible dirt cup of dust catcher provided by the present invention, is mainly provided with cup body and push-and-pull column, and push-and-pull column is worn Positioning, limit switch are realized in the cavity of cup body side, and by limit switch and the first locating slot, the second locating slot Including slip lid and elastomeric element, when slip lid slides to opening end, elastomeric element is detached from the first locating slot or the second locating slot, so that Push-and-pull column can slide in cavity, and when slip lid slides to positive stop end, elastomeric element is caught in the first locating slot or the second locating slot, It realizes and fixes.

Thus, space is received in the storage that this structure expands dirt cup in dust catcher compared to the prior art, and do not use when It waits and hides storage and receive space, it is easy to carry.
