A kind of toilet dredging device
Technical field
The present invention relates to machinery equipment field, specifically a kind of toilet dredging device.
Background technology
It is well known that plant equipment plays increasing effect in terms of people's production and living are helped, with science
The development of technology, the species of plant equipment is more and more, but in family expenses closestool dredging equipment this aspect, the dredging of automation
Equipment compares shortage.
Known work on hand personnel are actively solving the above problems, but above mentioned problem is there is presently no effectively being changed
It is kind.At present in family expenses closestool dredging equipment this aspect, the dredging device of automation compares shortage, more normal in social life
What is seen is manually dredged using instrument for defecation.The reason for toilet is blocked is the alkaline chemical combination of pipe bent position long time integration
Thing precipitation accumulation, so cause existing instrument for defecation to be often up to being acted on less than effective dredging, and manually operates and often makes
People feels uncomfortable, it is therefore desirable to which thinking designs suitable automatics to solve the problem.The present invention provides a kind of toilet
Dredger, devises two moving blocks and double leval jib is combined into reciprocating moving mechanism, and the mechanism connects compared to general cam
The reciprocating mechanism of bar composition, the advantage is that shake is smaller when being moved, deviate move back and forth the error of central axis compared with
It is small, it is more stable when being contacted with toilet, it is not easy to which that gas leakage occurs, make the curved intraductal atmospheric pressure of toilet not using this reciprocating
It is disconnected to change, so that tamper is constantly impacted, devised in the purpose of dredging, and the dredging mechanism so as to reach
Piston structure, using principle is injected, can will inject in toilet acid in motion process, with the alkaline matter in toilet bend pipe
Generation hair is answered, and reaches the purpose of more effective dredging toilet, and the design structure is simple, it is easy to processed.
The content of the invention
For prior art device solving the above problems, but above mentioned problem is there is presently no being improved,
