Complex deformation, is configured with clump weight on flexible liquid storing bag 141, and the weight of the clump weight is configured to be less than in fluid channel 13 and generate
Vacuum force so that vacuum force can overcome the weight of clump weight to do work.
In order to enable soiling solution can smoothly flow back into flexible liquid storage when losing vacuum force effect in fluid channel 13
To avoid flow direction elsewhere in bag 141, fluid channel 13 has around refluxing opening 131 to the depression portion of lower recess.
Second embodiment: above and below fluid channel shown in overlying relation described in the present embodiment and attached drawing 4
Positional relationship is corresponding.
With reference to the accompanying drawings 4 and attached drawing 5 shown in, oral area refluxing opening 231 directed downwardly, the refluxing opening are offered on fluid channel 23
231 are located at the downside of delivery outlet 22.Fluid channel 23 includes being located at the upstream subchannel 232 of 231 upstream of refluxing opening and being located at
The downstream subchannel 233 in 231 downstream of refluxing opening, upstream subchannel 232 include the distal opening 236 at refluxing opening 231, this
Distal opening 236 is aligned with about 231 refluxing opening.Specifically, upstream subchannel 232 includes one section of vertical pipe section 234, end
Opening 236 is located at the bottom of vertical pipe section 234.Downstream subchannel 233 includes the starting end opening at refluxing opening 231
237, downstream subchannel 233 includes one section of horizontal pipe section 235, and starting end opening 237 is located on horizontal pipe section 235.
In this example, fluid channel 23 is L-shaped, and refluxing opening 231 is located at the corner of L shape fluid channel, i.e. horizontal pipe section 235
With the junction of vertical pipe section 234.
In other embodiments, in order to ensure the liquid to flow back from delivery outlet 22 flows into as far as possible from refluxing opening 231 and
It is unlikely to splash to downstream subchannel 233 from refluxing opening 231, then the bore of the distal opening 236 of upstream subchannel 232 is little
In the bore of refluxing opening 231；In order to ensure soiling solution will not splash in downstream subchannel 233 again by refluxing opening 231,
And be possible to flow at suction inlet 21, it avoids treating cleaning ground and causes secondary pollution, then suction inlet 21 is not less than refluxing opening 231
It can.
The soiling solution collection device 24 that flows back includes flexible liquid storing bag 241, the flexibility liquid storing bag 241 inside fluid channel 23 by
To deformation is also easy to produce when vacuum force effect, flexible liquid storing bag 241 is connected on refluxing opening 231.
In this example, specifically, the working principle of flexible liquid storing bag 241 is as shown in 6~attached drawing of attached drawing 8.
With reference to the accompanying drawings shown in 6, (fluid channel 23 at this time when being acted on inside fluid channel 23 by vacuum force
Air pressure inside is less than external atmospheric pressure), fluid (mixture that fluid herein is gas and soiling solution) is together by suction inlet 21
It sucks and flows to delivery outlet 22, at the same time, flexible liquid storing bag 241 is inhaled into inside fluid channel 23, and occupies one
Space inside segment fluid flow channel 23, so that fluid channel 23 reduces in the sectional area being located at refluxing opening 231, such one
Coming, the flow velocity of fluid will become larger, can not be under compressed state in fluid according to bernoulli principle, the flow velocity of fluid is bigger, pressure
Strong smaller, 23 inside of fluid channel and extraneous pressure difference are bigger, and suction is stronger, also just improves the suction efficiency of soiling solution.
With reference to the accompanying drawings shown in 7, when losing vacuum force effect inside fluid channel 23, flexible liquid storing bag 241 is certainly
It is fallen after rise naturally under body gravity, and towards the external protrusion of fluid channel 23 and expands to form reservoir hemispherical, from
The soiling solution that delivery outlet 22 flows back, which will enter in reservoir, to be temporarily stored.
With reference to the accompanying drawings shown in 8, when being acted on again by vacuum force inside fluid channel 23, flexible liquid storing bag 241
Interior soiling solution will be taken away again.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
