DETAILED DESCRIPTION

[0049] The utility model will be further explained in detail in combination with the drawings and specific embodiments.

[0050] As Figure 1As shown, a new multifunctional push type cleaning vehicle, comprising a vehicle frame provided with a handle, a vehicle frame provided with a push vehicle power system and a high pressure steam suction cleaning system; the push vehicle power system comprises front wheels and rear wheels, the front wheels are installed at the front of the vehicle frame, the rear wheels are installed at the rear of the vehicle frame, the push vehicle power system is composed of three front wheels and two rear wheels, which are respectively installed on the front and rear sides of the vehicle frame, the three front wheels are installed at the front of the vehicle frame, the two rear wheels are respectively installed on the two sides of the rear of the vehicle frame, the radius of the rear wheel is larger than that of the front wheel, which ensures the stability and maneuverability of the vehicle.

[0051] As shown, Figure 2 The high pressure steam suction cleaning system is installed at the front of the vehicle frame, the rear of the high pressure steam suction cleaning system is provided with a brushing system, and the rear of the brushing system is provided with a garbage collection system; the high pressure steam suction cleaning system comprises a water tank, a high pressure steam generator and a dust collector, the water tank is installed on the vehicle frame, the high pressure steam generator is connected with the water tank through a pipeline, the high pressure steam generator is responsible for converting the water in the water tank into high temperature and high pressure steam, and conveying it to the high pressure steam gun. A high pressure steam gun is provided on the high pressure steam generator to output steam to the road surface, the high pressure steam gun sweeps the road surface by generating a rotating steam flow to deal with stubborn stains; the dust collector is arranged opposite to the nozzle of the high pressure steam gun, and the dust collector is used to suck up the dust and small garbage raised after the rotating steam flow sweeps the stubborn stains.

[0052] The nozzle of the high pressure steam gun is detachably installed on the high pressure steam gun, and the nozzle of the high pressure steam gun is composed of an inlet section, a contraction section, a diffusion section and a nozzle opening in sequence from top to bottom, steam enters the nozzle from the inlet section and first passes through the gradually narrowing contraction section, with the decrease of the cross-sectional area, the speed of the steam increases and the pressure decreases, after passing through the contraction section, the steam enters the gradually expanding diffusion section, the speed of the steam gradually decreases and the pressure rises, at the same time, the steam is accelerated to a higher speed and is ready to be sprayed from the nozzle opening, finally, the high speed steam is sprayed out through the outlet, forming a high pressure steam flow.

[0053] In order to meet the cleaning needs of different types of stains, the nozzle of the high pressure steam gun is designed in three forms, including a centralized nozzle, an inclined fan-shaped nozzle and a vertical fan-shaped nozzle, the operator can replace the nozzle according to the needs, and each nozzle has a specific application scene:

[0054] As shown, Figure 3 And Figure 4As shown, the orifice of the concentrated nozzle is rectangular in both front and side view. The working principle of the concentrated nozzle is based on the principle of pressure difference, that is, when high-pressure steam passes through the nozzle, due to the geometry inside the nozzle and the principle of fluid dynamics, the speed of the steam increases and the pressure decreases, and this pressure difference causes the surrounding liquid or gas to be sucked into the ejector. The nozzle controls the degree of expansion of the steam and converts the pressure into speed, thus concentrating the high-pressure steam in one place, so that the ejected steam flow has better impact force, suitable for spot cleaning.

[0055] As shown in Figure 5 and Figure 6 , the orifice of the oblique fan-shaped nozzle is fan-shaped in front view and triangular in side view. The oblique fan-shaped nozzle can obliquely spray high-pressure liquid in a fan shape. The liquid passes through the fan-shaped orifice under high pressure to form a fan-shaped jet, which not only makes the coverage area of the jet wider, but also maintains a relatively high jet pressure within a certain range, suitable for large-area surface treatment.

[0056] As shown in Figure 7 and Figure 8 , the orifice of the vertical fan-shaped nozzle is trapezoidal in front view and rectangular in side view. The working principle of the vertical fan-shaped nozzle is similar to that of the oblique fan-shaped nozzle, which is also designed based on the principle of fluid mechanics. High-pressure liquid passes through a special-shaped orifice to form a fan-shaped jet, and the fan-shaped jet has a small oblique angle. The effect on strongly adhering garbage will be better. This design allows the liquid to blow the garbage more evenly during the spraying process, making it suitable for applications that require strong adhesion and uniform distribution, and is particularly useful for removing stubborn dirt with strong adhesion.

[0057] The dust collector includes a dust suction nozzle, a dust suction pipeline, and a dust collection tank, and the dust suction nozzle is connected to the dust collection tank through the dust suction pipeline; as shown in Figures 9 to 11 , one side of the dust suction nozzle is provided with a funnel-shaped dust suction port, and the funnel-shaped dust suction port is close to the nozzle of the high-pressure steam gun. This design can more effectively capture dust and small garbage that is lifted by steam impact. The inlet part of the dust suction nozzle is tapered funnel-shaped, which can reduce air flow rate and thus reduce resistance. At the same time, the other side of the dust suction nozzle is provided with a circular-arc-shaped trailing edge to make the suction process smoother.

[0058] The dust suction nozzle is made of materials with natural low-friction properties (such as polytetrafluoroethylene, nickel-phosphorus alloy electroplating layer, or ceramic coating) and surface treatment (such as polishing treatment or nano coating) to reduce friction, so that the air flows more smoothly and reduces air resistance.

[0059] As a preferred embodiment, an L-shaped baffle is further provided in front of the dust collector to prevent the blown-up debris from spreading outward, further enhancing the cleaning efficiency and reducing the risk of secondary pollution.

[0060] As shown in Figure 12 , the high-pressure steam gun is rotatably connected with the high-pressure steam generator, and the dust suction nozzle is rotatably connected with the dust suction pipeline. In addition, the high-pressure steam gun and the dust suction nozzle can allow the operator to flexibly adjust the jetting angle and the dust suction angle according to the actual situation, so that the steam flow can effectively act on the ground surface, and at the same time the dust suction nozzle can timely remove the dirt, thereby achieving the best cleaning effect.

[0061] The water tank is detachably connected with the vehicle frame through the buckle structure. The water tank is fixed on the vehicle frame through the buckle structure, which is convenient for disassembly and cleaning or supplementing water source.

[0062] As shown in Figure 1 , Figures 12 to 14 , the brushing system includes a rolling brush, a belt, a motor and a battery. The rolling brush is installed at the bottom of the vehicle frame and located between the front wheel and the rear wheel, so as to effectively cover the cleaning area and maintain the balance of the vehicle body. The motor is arranged on the vehicle frame, and the rolling brush is drivingly connected with the output shaft of the motor through the belt. The motor is powered by the battery. Specifically, the rolling brush is fixedly provided with a rolling brush rotating shaft, and the rolling brush rotating shaft is rotatably installed at the bottom of the vehicle frame and is responsible for cleaning a large area of ground. The output shaft of the motor is connected with the rolling brush rotating shaft through a first belt to drive the rolling brush to rotate and realize power transmission. The motor is powered by the built-in battery, which ensures the portability and independent operation ability of the equipment.

[0063] In order to increase the cleaning range, the brushing system further includes circular corner brushes, two of which are arranged on the two sides of the vehicle frame and are also drivingly connected with the output shaft of the motor through the belt, which are specially used for cleaning corners and other difficult-to-reach edge areas.

[0064] Specifically, the brushing system further includes a transmission shaft, a first bevel gear, a second bevel gear, a second belt, a third belt, a connecting rod and a spring connecting piece. The output shaft of the motor is connected with the transmission shaft through the second belt. The end of the transmission shaft is provided with the first bevel gear, and the first bevel gear is engaged with the second bevel gear. The circular corner brush is fixedly provided with a circular corner brush rotating shaft, and the circular corner brush rotating shaft is connected with the second bevel gear through the third belt to drive the circular corner brush to rotate and realize power transmission. The circular corner brush is installed on the front side of the vehicle frame through the connecting rod. The connecting end of the connecting rod with the vehicle frame is rotatably connected. The inner side of the connecting rod is connected with the vehicle frame through the spring connecting piece. One end of the spring connecting piece is rotatably connected with the connecting rod, and the other end is rotatably connected with the vehicle frame. The elasticity provided by the spring connecting piece allows the circular corner brush to automatically adjust the expansion angle of the connecting rod according to the specific situation of the obstacle or the wall surface (such as protrusions, depressions or inclination), so as to ensure that the bristles of the circular corner brush are always closely attached to the obstacle or the wall surface.

[0065] The material of the roller brush and the circular corner brush is selected to be wear-resistant and friendly to the ground, so that effective cleaning can be performed without damaging the ground. By controlling the rotating speed of the motor, the rotating speed of the roller brush and the circular corner brush can be adjusted to adapt to different grounds and cleaning requirements. The brushing system is mainly used for sweeping large garbage.

[0066] As shown in Figures 15 to 17 , the garbage collection system includes a garbage bin mounted on the frame, and an opening is formed in the side of the garbage bin close to the roller brush. The position of the opening is matched with the roller brush, and the lower edge of the opening is connected with an inclined guide plate. The inclination angle of the guide plate is matched with the rotating path of the roller brush, so as to ensure that the garbage swept up by the roller brush can smoothly slide along the guide plate from the opening into the garbage bin. A garbage bin lifting door that can move up and down is also slidably connected to the opening, which is used to prevent the garbage from scattering.

[0067] The garbage bin is detachably connected with the frame through a buckle structure, which is convenient for the operator to quickly assemble and disassemble. Specifically, as shown in Figure 18 , the buckle structure includes a hook-shaped clamping piece arranged on the garbage bin, and a reverse hook-shaped clamping piece is arranged on the frame. The hook-shaped clamping piece and the reverse hook-shaped clamping piece are matched to detachably connect the garbage bin with the frame. The garbage bin also includes a garbage bin handle arranged on the outer wall of the garbage bin. When the garbage is full, the garbage bin handle can be used to pull out the garbage bin to pour out the garbage.

[0068] The material of the garbage bin is selected to be durable and easy to clean, so as to facilitate maintenance and cleaning. The garbage bin is mainly used for collecting large garbage such as small stones.

[0069] The working process of the novel multifunctional pushing type cleaning vehicle is as follows:

[0070] As shown in Figure 19 , the operator first ensures that the water tank of the cleaning vehicle is filled with water. According to the requirements of the cleaning task, the operator selects a suitable high-pressure steam gun nozzle (centralized nozzle, inclined fan-shaped nozzle or vertical fan-shaped nozzle) and installs it on the high-pressure steam gun. Ensure that the garbage bin is empty and correctly installed on the frame.

[0071] The operator holds the handlebar and pushes the cleaning vehicle forward through the trolley power system (including front wheels and rear wheels). When the cleaning vehicle reaches the area to be cleaned, the operator starts the high-pressure steam suction cleaning system. The high-pressure steam generator converts the water in the water tank into high-temperature and high-pressure steam and delivers it to the high-pressure steam gun. The nozzle of the high-pressure steam gun sprays high-pressure steam flow to flush the stubborn stains on the road surface. According to the type and distribution of the stains, the operator can also flexibly adjust the spray angle of the high-pressure steam gun.

[0072] At the same time of high-pressure steam cleaning, the vacuum cleaner starts to work, the suction nozzle is close to the nozzle of the high-pressure steam gun, effectively capturing the dust and small garbage raised by steam impact, and the suction nozzle transports the captured garbage to the dust collection box through the suction pipeline.

[0073] The roller brush rotates under the drive of the motor to clean large-area ground, and the circular corner brush is specially used for cleaning corners and other difficult-to-reach edge areas, and the operator can adjust the rotating speed of the roller brush and the circular corner brush according to needs to adapt to different ground and cleaning needs. The garbage swept up by the roller brush smoothly slides into the garbage can through the guide plate. When the garbage can is full of garbage, the operator can easily unload the garbage can from the frame through the garbage can handle and pour and clean.

[0074] Overall, the novel multifunctional pushing type cleaning vehicle of the present application combines high-pressure steam vacuum cleaning technology, brushing system and garbage collection system, aiming to provide a user with an efficient, environmentally friendly and easy-to-operate cleaning solution.

[0075] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as limiting the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
