Water tank cleaning machine

Abstract

The invention discloses a water pool cleaning machine which comprises an outer shell, a containing space formed in the interior of the cleaning machine, at least one water inlet arranged on the outer shell, at least one water outlet arranged on the outer shell, a plurality of wheels or rollers or wheels and rollers for matching arranged at the bottom of the outer shell; the bottom of the outer shell appears to be an incurved concave surface. By setting the bottom of the water pool cleaning machine to be an incurved concave surface, the invention causes the water pool cleaning machine to be able to smoothly pass when running into barriers at the bottom of a pool during underwater operation, which reduces the fault rate and the maintenance cost of the water pool cleaning machine and improves the working efficiency of the water pool cleaning machine without influencing negative pressure and water flow needed by the water inlet. Ulteriorly, the water inlet is arranged at the proper position of the outer shell of the water pool cleaning machine, such as close to the wheels and / or rollers, thereby ensuring the water inlet to suck sewage with deposits into the water pool cleaning machine.

Description

technical field [0001] The present invention relates to a pool cleaning device, in particular to the improvement of its bottom so as to prevent the pool cleaning machine from being stuck on the obstacle at the bottom of the pool and unable to move because the bottom is too low when the pool cleaning machine is working underwater. Background technique [0002] At present, the pool cleaners used for swimming pools etc. are generally divided into wheel type, drum type, chain belt type or liquid jet pool cleaners, generally as figure 1 As shown, the components include: an outer casing 100, which forms an accommodating space 110 inside; at least one water inlet 120, arranged on the outer casing 100; at least one filter bag 130, arranged in the container of the outer casing 100 placed in the space 110, and filter the water in the water inlet 120; at least one water outlet 140 is arranged on the outer casing 100 and at least one water pump 150 is correspondingly arranged in the at ...

Problems solved by technology

And this kind of skirt still has the danger of being stuck by the uneven bottom of the pool; moreover, this kind of skirt can't be sealed, otherwise the garbage or sediment can't pass through the skirt and be sucked into the cleaning machine, but the skirt without sealing feet, the water flow cannot be concentrated, thus generating insufficient negative pressure and water flow to bring up the garbage or sediment at the bottom of the pool

[0005] In summary, the existing pool cleaners obviously have inconveniences and defects in actual use, so it is necessary to improve them
