A kind of above-mentioned hydrocone type cleaner, the structure of exhaust unit 24 is mainly by base 28, air bag 25, the pump housing 27 and gland 26
Four parts form.When extruding gland 26, second flow unit 21 is closed, and the 3rd flow cell 23 is opened, the gas in air bag 25
Flowed out from outlet；When loosening gland 26, second flow unit 21 is opened, and the 3rd flow cell 12 is closed, and gas flows into from product are entered
In air bag 25；Pass through continuous such one operation for squeezing a pine, it is possible to pump the air in pipe.By in second space 29
Set air bag 25 that air is concentrated in air bag 25, cause exhaust unit 26 more so as to improve the exhaust effect of exhaust unit 26
Air in effective extraction tube, compared to by pinching elastic emulsion during by setting the user of gland 26 pressing exhaust unit 24
Ball is more comfortable, so that the exhaust effect of exhaust unit 24 is more preferable.
The utility model is simple in construction, practical, by setting first flow control unit to ensure that the water of suction is unidirectional
Smoothly discharge does not produce suck-back phenomenon for circulation, so as to ensure the stabilization of cleaner drainage works.By being filled at exhaust unit both ends
If second flow control unit and the 3rd flow controlling unit so that flow direction one of the water in the first water pipe and the second water pipe
Cause.By by pinching exhaust unit, then loosen, continuous one pinches the operation of a pine, it is possible to pumps the air in pipe, in water pipe
Condition of negative pressure is createed, realizes the effect of siphon drainage.
The sewage diffusion effectively prevented using interval setting by siphon water seepage hole on hairbrush fixed plate outer ring, first
The design of opening is in order to which further sewage pump drainage is gone out.The main purpose of first flow control unit is to prevent built in brush
Only clear up when lift it is too high cause air enter pipe in.
By being provided with the hairbrush fixed plate of hairbrush, using brush, wipe the mode carried out simultaneously remove in fish jar incrustation scale with
Feeding residue and fish excrement, the residue to be come off when cleaning is together taken out of fish jar with waste water while cleaner draining, and then cause
Cleaning of the cleaner to fish jar is more thorough.
By setting the whole brush of a fulcrum to be rotated around fulcrum on brush holder stator.Pass through brush
Carry out rotation to be easy to clean fish jar corner, and then make fish jar cleaning easy and convenient and mitigate the work that people clean fish jar
Measure.
By installing the 4th flow controlling unit in the second water pipe, gas discharge in pipe is allowed to produce by exhaust unit is pinched
Stable siphonic effect makes waste water constantly discharge, and the displacement of cleaner is controlled by the 4th flow controlling unit, is further protected
Demonstrate,prove the stabilization of cleaner drainage works.
It is open by setting first in hairbrush fixed plate as circle so that suction is uniform, and then absorbs brush, the fish after wiping
Incrustation scale and feeding residue and fish excrement and stable draining in cylinder.
This example course of work：
When liquid device is contained in cleaning, brush is immersed into below liquid level, the port of hairbrush fixed plate is placed in the dirty dress of Sheng of lower
In putting, the valve on the second water pipe is opened, exhaust unit is pressed with hand, then is loosened, continuously one by a loose operation repeatedly, takes out
The air gone out in pipeline pumps, until there are flowing out, it is possible to starts to clean.In cleaning process, to prevent from fixing hairbrush
Plate leaves liquid level.
Specific embodiment of the present utility model is above are only, but design concept of the present utility model is not limited thereto,
All changes for carrying out unsubstantiality to the utility model using this design, all should belong to the row for invading scope of protection of the utility model
For.
