Description
Technical field
The utility model relates to sweeper field, the circulated air for particularly relating to sweeper helps pressure-vaccum disk.
Background technique
Traditional sweeper sucker does not have circulated air to help blowing structure, and only there are two chambers, i.e. negative pressure absorbing chamber and high pressure punching for sucker
Chamber is washed, sucker high pressure washing main jet bar is mounted in the intracavitary portion of high pressure washing.It has the defects that it is more such as: (1) wash and sweep operation consumption
Height, usage charges are high；(2) it since only there are two chambers for sucker, rinses splash in order to prevent, need high pressure washing chamber being made larger,
Due to flooding nozzle spray cascade be it is fan-shaped, the air entered below in this way some can be from the cascade on cascade top
Intersect neutral gear and enter negative pressure absorbing chamber, reduces the absorption efficiency of sewage and rubbish, in addition air-flow can also cause cascade centainly
Disturbance, influence flushing effect.The above reason Hui Shi cascade lap-joint and non-overlapping place form apparent cleannes difference and
Ground forms zebra stripes to influence ground cleaning effect；(3) because therefore suction nozzle low efficiency needs the power of blower big, make
Working-noise increases；(4) containing part, wet dust particle does not cause secondary pollution to atmosphere in the air of blower discharge；
(5) sucker high pressure washing main jet bar is difficult mounted in the intracavitary portion's maintenance of high pressure washing.
Based on this, a kind of energy-efficient, environmentally friendly, easy to maintain sweeper sucker is exactly what present society was needed.
