Abstract
An air pressure-type manual drain cleaner comprises a hollow handle and a movably-matched piston rod positioned in the hollow handle; the lower end of the hollow handle is connected with a pressure housing and is communicated with the inner chamber of the pressure housing; and an elastic membrane is sealed and covered at the opening part at the lower end of the pressure housing. When in use, all that is needed is to align the lower end of the pressure housing closely to a pipeline port, so that pressure in the pressure housing can be varied due to the pushing of the piston rod, the elastic membrane is outwardly bulged or inwardly concaved, air pressure in the pipeline is also correspondingly rapidly changed, and bulkheads are easily vibrated to drop off. The utility model has the advantages of simple and reasonable structure, defacement avoidance, cleanness and sanitation, and convenient use, and can be used without stretching into the pipeline.
Description
Technical field:
The utility model relates to a kind of pipeline drainer.
Background technology:
Multiple pipeline drainer has been arranged now, and some utilizes flexible axle to lead to pipe interior and stirs obstruction, and also some utilizes air pressure vacuum principle that obstruction is dropped.But general air pressure vacuum dredging device all is to utilize piston or leather cup to fill in to promote in the pipeline to need directly to contact with the tube wall inner chamber to change air pressure, also takes the sewage foreign material after pulling out easily out of, not enough health.And, if tube wall is smooth inadequately, also than being easier to make piston or leather cup breakage.
Summary of the invention:
At the deficiencies in the prior art, the utility model provides a kind of health, vapour-pressure type rational in infrastructure used manually to manage logical dredging device.
The piston rod that the utility model comprises hollow handle and is placed in one and move cooperates, the lower end of hollow handle be connected with pressure enclosure and and its inner chamber be communicated with, the lower ending opening place of this pressure enclosure then seals the flexible diaphragm of covering.
Only need be when the utility model uses with the pressure enclosure lower end tightly to pipeline opening, piston rod promotes to make the pressure in the pressure enclosure to change, and then makes flexible sheet external drum or indent, the also corresponding rapid change of air pressure in the pipeline, obstruction is easy to be vibrated drop.Of the present utility model simple and reasonable, need not to stretch in the pipeline and can use, avoid stained, clean hygiene uses easily.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings:
Accompanying drawing is the main structure schematic diagram of embodiment.
Embodiment:
As shown in the figure, piston rod 3 places hollow handle 1 to move to cooperate, the lower end of hollow handle 1 be connected with pressure enclosure 2 and and its inner chamber be communicated with, the lower ending opening place of this pressure enclosure 2 then seals the flexible diaphragm 4 of covering.General hollow handle 1 and pressure enclosure 2 are integrated formed structures, and it is convenient reasonable to produce like this.Generally also can be provided with in the upper end of piston rod 3 and to hold ring 6, operation easily, it is convenient that the time spent does not hang yet.
