Above-mentioned power cavity 1, wedge centering block 2, cover plate 3, power suction pipe 4 and water recovery apparatus 5 consist of the power set A of cleaner for bottom of pool, the water inlet end of these power set A is the water inlet 11 of power cavity 1, and the water side 12 of these power set A is the outfall 531 of water recovery apparatus 5.
The operating principle of present embodiment is:
At the bottom of the cleaner for bottom of pool of present embodiment put into the pond, at first regulate the position of floating ring 9 on flexible pipe 8 according to the depth of water, so that cleaner can obtain a preferable putting position in water, simultaneously, the joint overcoat 72 of pipe can be rotationally connected, because joint overcoat 72 and retainer ring 74 are fixedly linked, and retainer ring 74 is connected with power set A, so, joint overcoat 72 can be done freely rotating in the 360 degree scopes with respect to joint 71, need not to drag the flexible pipe 8 that is connected on the joint 71, just can freely adjust the orientation of cleaner head in the pond.
After regulating the position of cleaner in the pond, the logical power supply of going up starts water pump, at this moment, current, and flow out respectively from two delivery ports of this power cavity 1 through two different passages through the ellipse hole of cover plate and enter within the power cavity 1 from the water inlet of power cavity;
The cross section diminishes suddenly flow into the passage of first side through the through hole 31 on the cover plate 3 owing to current after, so can produce certain suction in the water stream channel of this first side, wedge centering block 2 under the effect of this suction to the wherein side oscillation of power cavity 1 water inlet 11, and seal this first side water stream channel, water flows through from the second side water stream channel, because the effect of water recovery apparatus, when water from the second side water stream channel when power suction pipe 4 flows into first water inlet of water recovery apparatuses 5, owing to offer the slotted eye 541 that is connected with housing 52 on the return pipe 54, part water flows out through the outfall 531 of water recovery apparatus 5, another part water then flows back in the water stream channel of being sealed through second water inlet of water recovery apparatus 5, so, hydraulic pressure vanishing in the water stream channel of being sealed, act on the also vanishing of suction of this side, wedge centering block 2 does not stress at this moment, and the water in second wing passage of flowing through be because the variation of water flow section can produce a suction equally, and wedge centering block 2 is swung to opposite side again under the suction of this second side water stream channel.
Reciprocal thus, wedge centering block 2 will be at water inlet 11 places of power cavity 1 back and forth swing and knock the inwall of power cavity, knock the power cavity inner wall and the power that produces can make cleaner produce a displacement at the bottom of the pond by wedge centering block 2, cleaner is moved at the bottom freely.
The cleaner of present embodiment can be connected on the small-power water pump of 0.1～0.75HP and realize purpose at the bottom of the automatic pool cleaner, be specially adapted in small-scale terrestrial swimming pool or pond, use, be arranged on the continuous swing that water recovery apparatus on the cleaner can guarantee centering block, prevent generation centering block stuck phenomenon because the suction of one-sided water stream channel is excessive, and the slit that is opened on the return pipe can also be convenient to go out booties such as water-bed dirt, leaf, anti-stopping power suction pipe obstruction.
The cleaner for bottom of pool compact conformation of present embodiment, volume are little, easy to maintenance, and price is more cheap, and this cleaner for bottom of pool can directly drive by the small-power water pump, and low in energy consumption, it is convenient more flexibly to use.
