Abstract
The invention discloses a sewer dredging device. The dredging device comprises a pull rod, a piston, a valve and a suction cup, wherein the pull rod extends into an air cylinder of the dredging device; the piston is arranged at the lower end of the pull rod and does piston motion under the traction of the pull rod; the valve is positioned at the upper end of an exhaust port and is hinged with the piston; the suction cup is positioned at the lower end of the air cylinder, is inverted bowl-shaped and is made of a rubber material. In use, after the suction cup is sucked to an inlet of a sewer to be dredged, the pull rod is lifted to drive the piston to do suction action, and the valve seals the exhaust port under the action of external air pressure so as to form negative pressure in the air cylinder. At the time, blockages in the sewer are sucked out under the action of the negative pressure, so that the aim of dredging the sewer is fulfilled.
Description
Technical field
The present invention relates to a kind of sewer dredger, particularly relate to a kind of sewer dredger that has piston apparatus and sucker.
Background technology
In daily life, the sewer obstruction is the thing that a lot of families all ran into.The convenient disposal mode of general family all is to use traditional sewer dredger that has sucker.When mediation, can only rely on the space at sucker itself and sewer road junction, firmly press down, produce negative pressure, thus the sucking-off obstruction.But because traditional dredger in use, the negative pressure that can produce is very little, and is limited to the dynamics that obstruction is extracted.So when dredging sewer, traditional help that dredger brought is very little.
In sum, problem demanding prompt solution is, makes people when use has the sewer dredger of sucker, and the sucker place can produce bigger negative pressure, more effortlessly with the sucking-off from sewer of sewer obstruction.
Summary of the invention
Technical problem to be solved by this invention is, a kind of sewer dredger is provided, and more specifically, relates to a kind of sewer dredger that has piston apparatus and sucker.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of sewer dredger, and this dredger comprises: pull bar, it stretches among the inflator of dredger; Piston, it is installed on the lower end of said pull bar, under the traction of said pull bar, does piston motion; Valve, it is positioned at the upper end of exhaust opening, and is connected for hinge between the said piston; Sucker, it is positioned at the lower end of inflator; Said sucker is inverted bowl-type, and adopts elastomeric material to process.
Advantage of the present invention is; Be provided with piston apparatus and sucker in the disclosed sewer dredger of the present invention; During use; After sucker is adsorbed in inlet of sewer place to be dredged, lifts pull bar and drive piston and make aspiratory action, thus valve externally the action of air pressure lower seal live exhaust opening in the inner negative pressure that forms of inflator.Obstruction in the sewer by sucking-off, reaches the purpose of dredging sewer under action of negative pressure at this moment.
Description of drawings
Fig. 1 is the internal construction sketch map of sewer dredger of the present invention.
The specific embodiment
For further disclosing technical scheme of the present invention, be described with reference to the accompanying drawings embodiment of the present invention now:
Fig. 1 is the internal construction sketch map of sewer dredger of the present invention, among the figure, comprising: pull bar 10, and it stretches among the inflator of dredger; Piston 11, it is installed on the lower end of said pull bar 10, under the traction of said pull bar 10, does piston motion; Valve 12, it is positioned at the upper end of exhaust opening 13, and is connected for hinge between the said piston 11; Sucker 20, it is positioned at the lower end of inflator, and in order to be easy to use, this sucker 20 can be inverted bowl-type, and adopts elastomeric material to process.
Be provided with piston apparatus and sucker in the above-mentioned sewer dredger; During use; After sucker is adsorbed in inlet of sewer place to be dredged, lifts pull bar and drive piston and make aspiratory action, thus valve externally the action of air pressure lower seal live exhaust opening in the inner negative pressure that forms of inflator.Obstruction in the sewer by sucking-off, reaches the purpose of dredging sewer under action of negative pressure at this moment.If, once can not accomplish mediation work, only need depress pull bar, valve is opened under the effect of internal air pressure, air unnecessary in the inflator is discharged through exhaust opening, accomplish above-mentioned exhaust action after, repeat above-mentioned aspiratory action and can dredge once more.
More than, basic design of the present invention and basic principle have been set forth through introduction to listed embodiment.But the present invention never is limited to above-mentioned listed embodiment, and every equivalent variations, improvement and deliberately of inferior quality behavior of doing based on technical scheme of the present invention of change all should belong to protection scope of the present invention.
