Referring to fig. 1 to 8, a portable hydro-power cleaner includes an upper cylinder cover 100, a lower cylinder cover 200, a body 300, a triangle piston 400, a bearing 500, a main shaft 600, a brush head 700, and a handle 800, wherein:

The upper cylinder cover 100 and the lower cylinder cover 200 are respectively arranged at the upper end and the lower end of the machine body 300 to form a piston cavity 330, the triangular piston 400 is arranged in the piston cavity 330, one end of the main shaft 600 is positioned in the piston cavity 330, the other end of the main shaft 600 is connected with the brush head 700, and the handle 800 is arranged on the machine body 300;

The triangular piston 400 is a circular triangle, a through hole 410 is formed in the center of the triangular piston 400, a circle of inner gear 411 is arranged at one end of the through hole 410, an outer gear 210 is arranged in the center of the upper surface of the lower cylinder cover 200, the inner gear 411 and the outer gear 210 are meshed, the tooth ratio of the inner gear and the outer gear is 3:2, when the triangular piston 400 rotates for one circle, the main shaft 600 rotates for three circles, and when the triangular piston 400 rotates, three edges of the triangular piston 400 always contact with the inner wall of the machine body 300; the main shaft 600 is provided with an eccentric protruding shaft 610 having a larger diameter than the main shaft 600, and the protruding shaft 610 is fitted into the through hole 410 of the triangular piston 400 through the bearing 500; the inside of the machine body 300 is provided with a water inlet pipe 310 and a water inlet channel 320 which are communicated, the upper surface of the lower cylinder cover 200 is provided with a first water inlet channel 220, a second water inlet channel 230 and two water outlet holes 230, the first water inlet channel 220 and the second water inlet channel 230 are communicated with the piston cavity 330, the water outlet holes 240 are connected with a water outlet channel 250 below the lower cylinder cover 200 and are communicated with the brush head 700 through a water outlet channel 620 in the main shaft 600.

In order to cope with various inclined surfaces, the main shaft 600 is connected with the brush head 700 through a universal ball head 1100, so that the brush head 700 can freely rotate within a certain range.

To increase the cleaning ability, a cleaner cylinder 1000 is installed above the water inlet pipe 310, the inside of the cleaner cylinder 1000 is communicated with the water inlet pipe 310, the cleaner cylinder 1000 is filled with the cleaning agent, and a small amount of water flow in the water inlet pipe 310 enters the cleaner cylinder 1000 to carry the cleaning agent out.

In order to prevent the triangular piston 400 from being rotated by the water pressure when it is at the equilibrium position, the first water inlet groove 220 and the second water inlet groove 230 are symmetrically distributed with the center of the external gear 210 as the center of symmetry, and the two water inlet grooves can generate moment to the triangular piston 400 to rotate.

In order to facilitate processing while reducing resistance to water flow, the first water inlet channel 220 and the second water inlet channel 230 have a kidney-shaped structure, one end of which is connected to the water inlet channel 320, and the other end of which is located in the piston chamber 330.

An adjustable switch 900 is arranged on the handle 800, and the water inflow of the cleaner can be adjusted through the switch 900, so that the rotating speed of the triangular piston 400 is controlled, and the rotating speed of the brush head 700 is adjusted according to the requirement.

The working principle of the invention is similar to that of a rotary engine, and referring to fig. 7 and 8, the principle is as follows:

Principle of rotation: as shown in fig. 7, the triangular piston 400 divides the piston chamber 330 into a plurality of chambers, and water flows from the water inlet channel 320 into the first water inlet channel 220 and the second water inlet channel 230, at this time, since the water flowing out of the first water inlet channel 220 has a certain pressure and is not perpendicular to the surface of the triangular piston 400, it can push the triangular piston 400 to rotate, and when the triangular piston 400 rotates, the water which has acted in other chambers flows out through the water outlet holes 240; as shown in fig. 8, after the triangular piston 400 rotates by a certain angle, the first water inlet groove 220 is aligned with the other surface of the triangular piston 400, and at this time, the piston cavity 330 is communicated with the second water inlet groove 230, and water flows out of the second water inlet groove 230 to apply work, so that the triangular piston 400 rotates. Because the first water inlet tank 220, the second water inlet tank 230 and the two water outlet holes 240 are always located in different chambers, and the first water inlet tank 220 and the second water inlet tank 230 always have water inlet and are distributed in a central symmetry manner by taking the center of the external gear 210 as a symmetry center, the moment can always act on the triangular piston 400, and the constant rotation of the triangular piston is ensured; when the triangle piston 400 rotates, it is meshed with the external gear 210 through gears, the thrust between teeth ensures that no slip is generated when the triangle piston 400 rotates and pushes the protruding shaft 610 to rotate through the bearing 500, and the protruding shaft 610 rotates along with the rotation of the triangle piston 400 to give a moment to the main shaft 600 to rotate, thereby driving the brush head 700 to rotate, and cleaning is completed.

The water flow process comprises the following steps: the water flows into the water inlet channel 320 through the water inlet pipe 310, works on the triangular piston 400 through the first water inlet channel 220 and the second water inlet channel 230, flows into the water discharge channel 250 from the water outlet hole 240 after the work is finished, and then flows into the brush head 700 through the water discharge channel 620 in the main shaft 600, so as to clean the surface of an object.

The invention has the design key points that the water flow can directly drive the brush head to rotate and flow out by utilizing the matching of the triangular piston and the main shaft, so that the object can be cleaned without an external power supply, and the cleaning device is safe and convenient; the water pressure always works in the piston cavity, so that the water resource utilization rate is high, and the energy is saved; the cleaner provided by the invention has small volume and light weight, can be used for cleaning various scenes such as bath and various object surfaces besides car washing, and has a very wide application range.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical principles of the present invention still fall within the scope of the technical solutions of the present invention.
