Abstract
The utility model discloses a dust collector having a novel collecting mouth seal ring, which at least comprises a dust cup arranged in a vacuum chamber of the dust collector, a turnover cover which comprises a main collecting mouth and can shield the dust cup, and a collecting mouth seal ring mounted between the dust cup and the turnover cover, the collecting mouth seal ring comprises an annular base part, an upper side edge formed by the base part extending upwardly, a lower side edge formed by the base part extending downwardly, and a folding edge extending from a terminal of the lower side edge to the external side. The utility model can ensure that the seal ring and the main collecting mouth can form an effective seal, thereby preventing the gas leakage of the dust cup.
Description
Technical field
The utility model relates to a kind of dust catcher with novel suction inlet sealing ring, especially dirt cup dust catcher.
Background technology
The sealing means of the main suction inlet of existing dirt cup dust catcher is to take the end face of sealing ring and near the flange inner face the import of dirt cup to seal, but because the about pressure reduction of sealing ring, require the end face fit dimension precision of sealing ring higher, and through using for a long time, the end face of sealing ring also is easy to generate distortion, cause seal failure, cause gas leakage thus, influence the filter efficiency of dirt cup.
Summary of the invention
The utility model purpose is: a kind of dust catcher with novel suction inlet sealing ring is provided.
A technical scheme of the present utility model is: a kind of dust catcher with novel suction inlet sealing ring, it comprises at least: the dirt cup of dust catcher vacuum chamber, contain main suction inlet and cover the dirt cup renovate and be installed in the dirt cup and renovate between the suction inlet sealing ring, described suction inlet sealing ring comprise annular base portion, by base portion extend upward the last lateral margin that forms, the lower lip that forms by base portion extension downwards and the flange that extends laterally by the end of lower lip.
The cup of dirt described in the utility model comprises an import and is positioned at the flange at the edge of import that comprise a main suction inlet and renovate, this main suction inlet has a stage portion.
The base portion of the sealing ring of suction inlet described in the utility model and last lateral margin, with the stage portion corresponding matching of main suction inlet, the flange of described suction inlet sealing ring then is fitted on the flange of dirt cup.
Flange described in the utility model and lower lip are an angle.
Go up the height of the height of lateral margin described in the utility model greater than lower lip.
Another technical scheme of the present utility model is: a kind of novel suction inlet sealing ring that is applied in the dust catcher, it comprise annular base portion, by base portion extend upward the last lateral margin that forms, the lower lip that forms by base portion extension downwards and the flange that extends laterally by the end of lower lip.
The utility model advantage is:
The utility model is avoided because the inaccurate gas leakage problem of bringing of fit dimension effectively because the about pressure reduction of sealing ring uses the sealing ring turnup structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 for of the present utility modelly renovate, sealing ring, the schematic perspective view of dirt cup before assembling;
Fig. 2 for of the present utility modelly renovate, sealing ring, the partial sectional view of dirt cup after assembling;
Wherein: 10, dirt cup; 12, import; 14, flange; 20, renovate; 22, main suction inlet; 30, sealing ring; 32, base portion; 34, go up lateral margin; 36, lower lip; 38, flange; 220, stage portion.
The specific embodiment
Embodiment: shown in Fig. 1-2, the utility model provides a kind of dust catcher with novel suction inlet sealing ring, and it comprises at least: the dirt cup 10 of dust catcher vacuum chamber, contain main suction inlet 22 and cover dirt cup 10 renovate 20 and be installed in dirt cup 10 and renovate suction inlet sealing ring 30 between 20.Wherein dirt cup 10 comprises an import 12 and the flange 14 that is positioned at the edge of import 12, comprises a main suction inlet 22 and renovate 20, and this main suction inlet 22 has a stage portion 220.
Suction inlet sealing ring 30 comprise annular base portion 32, by base portion 32 extend upward the last lateral margin 34 that forms, the lower lip 36 that forms by base portion 32 extensions downwards and the flange 38 that extends laterally by the end of lower lip 36, wherein this flange 38 is an angle with lower lip 36, be preferably the obtuse angle, the height of last lateral margin 34 is greater than the height of lower lip 36.
During installation, suction inlet sealing ring 30 covers are installed on the main suction inlet 22, the base portion 32 of suction inlet sealing ring 30 and last lateral margin 34 thus, with stage portion 220 corresponding matching of main suction inlet 22, and flange 38 is close on the flange 14 of dirt cup 10, even have the gap between flange 38 and the flange 14, because there is pressure reduction in suction inlet sealing ring inside and outside, this flange 38 rotates, and closely is fitted in thus on the flange 14, prevent gas leakage thus, on the position of main suction inlet 22, form effectively sealing.Similarly, suction inlet sealing ring of the present utility model also can be applied in the dirt bag dust catcher.
Certainly the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the people who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.The all spiritual essence of main technical schemes is done according to the present invention equivalent transformation or modification all should be encompassed within protection scope of the present invention.
