[0002] High-pressure cleaning machines can generate high-pressure water jets to wash the surface of objects, so that the dirt on the surface of objects is washed away by the high-pressure water jets, so as to achieve the purpose of cleaning the surface of objects. For example, a high-pressure car washing machine uses a water pump to pressurize water and then spray it from a spray gun onto the surface of the car, thereby washing away oil, dust, stains, etc. on the surface of the car body. Common high-pressure cleaning machines usually include a body, a booster pump, a hose reel, a water pipe, a spray gun and other components. The water pipe is wound on the hose reel, one end of the water pipe is connected to the booster pump, and the other end of the water pipe is connected to the spray gun. The water inlet end of the booster pump is connected to the external water pipe. The high-pressure water pipe can be lengthened according to actual needs. After use, the hose reel needs to be manually rotated to wind the water pipe. The water pipe winding resistance is large, and a large hand strength is required to wind the high-pressure water pipe.

[0026] like Figure 7 , Figure 8 and Fig. 9 As shown, the one-way rotation drive mechanism 12 includes a rack 120 arranged on the side of the slide rod 6, a gear ring 121 fixed at the center of the inner end of the hose reel, a transmission shaft 122 is provided on the connecting plate, the transmission shaft is rotatably connected with the connecting plate, a second transmission gear 123 is fixed to the lower end of the transmission shaft 122, the second transmission gear is meshed with the gear ring, a first transmission gear 124 is provided at the upper end of the transmission shaft 122, the first transmission gear is meshed with the rack, and a one-way bearing 125 is provided between the first transmission gear and the transmission shaft; when the pedal is pressed downward, the one-way bearing is in a locked state, and when the pedal is released and the slide rod moves upward under the action of the reset spring, the one-way bearing is in a free rotation state.

[0027] like Figure 2As shown, bottom wheels 16 are provided on both sides of the lower end of the frame 1, a handle 17 is provided on the upper end of the frame, and a cover plate 18 is provided on the right side of the frame; a spray pipe 19 and a spray gun 20 are also provided on the side of the frame 1, a spray pot seat 21 is provided on the lower side of the armrest on the frame, and a spray pot assembly 22 is provided on the spray pot seat; a hand crank 30 is provided at the outer end of the hose reel 3.

[0028] like Fig.10 As shown, a connecting shaft 70 is provided at the outer end of the pedal 7, a rotating roller 71 is provided on the connecting shaft, and a plurality of anti-skid grooves 72 are provided on the top surface of the pedal.

[0029] like Figure 8 and Fig.10 As shown, the hose reel 3 includes an inner hose reel body 300 and an outer hose reel body 301. An inner connecting tube 302 is provided at the center of the inner hose reel body 300, and a plurality of buckles 303 are provided on the inner connecting tube. An outer connecting tube 304 is provided at the center of the outer hose reel body 301, and a buckle seat cooperating with the buckle is provided on the outer connecting tube. The outer connecting tube and the inner connecting tube are coaxially buckled and connected, and the center of the outer connecting tube is rotatably connected to the rotating shaft.

[0030] Combined with the accompanying drawings, the principle of the present invention is as follows: add a water inlet joint on the pump to connect with the external water pipe, the water is pressurized by the booster pump and then discharged through the water pipe, and when in use, select a suitable spray pipe, spray gun or spray pot assembly to connect with the water pipe according to actual needs. There is cleaning liquid in the spray pot assembly. When washing the car, the high-pressure water sprayed from the spray gun rinses the surface of the car body to achieve cleaning; after use, the water pipe needs to be rewound on the reel, and at this time the user steps on the pedal up and down with his feet, thereby driving the sliding rod to reciprocate, and when the sliding rod moves downward, the first gear is driven to rotate through the rack, and at this time the one-way bearing is in a locked state. Therefore, the first gear drives the transmission shaft to rotate synchronously, and the second gear rotates synchronously with the transmission shaft. When the second gear rotates, it drives the gear ring to rotate. Since the gear ring is fixed to the hose reel, the hose reel rotates to reel the water pipe. When the foot moves upward, the slide bar resets upward under the action of the reset spring, and the one-way bearing rotates in the opposite direction. The one-way bearing is in free rotation, so the first gear cannot transmit power to the transmission shaft, and the hose reel will not rotate. When the pedal moves downward again, the hose reel rotates again, and the slide bar reciprocates up and down to realize the intermittent one-way rotation of the hose reel, thereby realizing the reeling of the water pipe. This high-pressure cleaning machine reels the water pipe by stepping on the pedal. The human foot has great strength, and the process of bending over is also avoided, making the reeling of the water pipe more convenient and labor-saving. At the same time, the one-way rotation drive mechanism is arranged in the isolation chamber to be isolated from the outside, so the overall performance is more stable and safer to use.

[0031] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
