Description

Technical Field

[0001] This invention relates to the field of foam machine technology, and specifically to a foam machine with adjustable water-liquid-gas ratio. Background Technology

[0002] Foam machines, as devices for generating foam, are commonly used for cleaning vehicles, walls, floors, etc. They typically involve mixing detergent, water, and air to form foam, which is then sprayed evenly onto the corresponding surface to remove oil and dust. Traditional foam machines suffer from technical drawbacks such as limited foam lift or excessive foam dispersion due to uncontrollable fan airflow. Specifically, with high airflow, a large amount of foam is easily dispersed, resulting in uneven foam distribution; with low airflow, the equipment's lift and pressure are limited, leading to poor adhesion between the foam and the dirt on the surface, resulting in ineffective cleaning.

[0003] Patent CN213610764U discloses a foam machine, comprising: an air inlet channel; a liquid inlet channel with a pump body mounted on it; a tank with one end of the liquid inlet channel connected to it; and a confluence section where the air inlet channel and the liquid inlet channel are interconnected. The confluence section has an outlet. The pump body draws liquid into the tank through the liquid inlet channel and drives the liquid to flow towards the confluence section. Gas and liquid mix at the confluence section before being discharged through the outlet. This foam machine's pump body can draw liquid from the tank, providing power to the liquid and enabling the tank to operate under open, normal pressure conditions, preventing the tank from bursting due to pressure. However, this foam machine cannot effectively adjust the water-liquid-gas ratio and cannot increase the pump head. Summary of the Invention

[0004] In view of this, the present invention provides a foam machine with adjustable water-liquid-gas ratio, which aims to solve the technical problems of uneven foam spraying and low head in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention provides a water-liquid-gas ratio adjustable foam machine, including a housing and a spray gun.

[0006] The box contains a gas storage tank, a water storage tank, and a detergent storage tank. Each of the gas storage tank, the water storage tank, and the detergent storage tank is connected to a pressurization pipe and an output pipe.

[0007] The spray gun includes a gas pipe and a liquid pipe connected to the output pipe, a nozzle gas supply pipe and a foam generating gas supply pipe connected to the gas pipe, a liquid supply pipe connected to the liquid pipe, a nozzle connected to the liquid supply pipe, a foam generator disposed at the end of the nozzle, and a nozzle disposed at the end of the foam generator. The nozzle gas supply pipe is connected to the nozzle. The foam generating gas supply pipe is equipped with a manual adjustment screw and a pressure regulating valve.

[0008] By adopting the above technical solution, gas is stored in the gas storage tank, water in the water storage tank, and washing liquid in the washing liquid storage tank. Gas, water, and washing liquid are replenished to the gas storage tank, water storage tank, and washing liquid storage tank respectively through a pressurization pipeline, and then output from the output pipeline. The output gas enters a gas pipeline, which connects to the nozzle gas delivery pipeline and the foam generation gas delivery pipeline. The output water and washing liquid enter a liquid pipeline, reaching the nozzle. The mixture of gas in the foam generation gas delivery pipeline and the liquid sprayed from the nozzle enters the foam generator to form foam, which is then sprayed from the nozzle. The nozzle gas delivery pipeline is connected to the nozzle to increase the nozzle head. Two gas paths are designed: one path mixes gas with water and washing liquid to form foam in the foam generator; the other path connects to the nozzle to increase the nozzle head. A manual adjustment screw and a pressure regulating valve work together to control the gas flow rate on the foam generation gas delivery pipeline.

[0009] Specifically, the output pipeline includes a gas output pipeline and a mixed liquid output pipeline. The end of the spray gun is provided with a gas filling port and a mixed liquid filling port. The gas output pipeline is connected to the gas pipeline through the gas filling port, and the mixed liquid output pipeline is connected to the liquid pipeline through the mixed liquid filling port.

[0010] The gas is delivered into the gas pipeline through a gas output pipe and a gas filling interface. The mixed liquid output pipe is connected to a water storage tank and a washing liquid storage pipe, which delivers water and washing liquid into the liquid pipeline.

[0011] In addition, the gas pipeline has a gas storage chamber at its end, the infusion pipeline passes through the gas storage chamber, and a rotating disc is rotatably connected to the infusion pipeline. The rotating disc is provided with an inclined exhaust slit.

[0012] By adopting the above technical solution, the gas in the gas pipeline reaches the gas storage chamber, and the gas drives the rotating disc to rotate through the exhaust slit, which blows air onto the foam generator. This makes the gas addition more uniform, improves the foaming efficiency, and allows for the time interval for the mixed liquid to form a water film on the foaming net of the foam generator, thereby increasing the water film forming speed and further improving the foaming quality.

[0013] In addition, the infusion pipeline is provided with a positioning hole, the foam generating gas pipeline is provided with an air hole, and the pressure regulating valve includes a rod body disposed between the positioning hole and the air hole, and a return spring connecting the rod body and the positioning hole. The upper part of the rod body has a hollow structure.

[0014] By adopting the above technical solution, rotating the manual adjustment screw allows gas to be introduced. When the gas pressure is high, the rod is pressed down, and the gas enters the gas storage chamber through the hollow structure on the rod. When the gas pressure is low, the rod rises under the action of the return spring, and the amount of gas passing through the gas delivery pipeline is small.

[0015] Preferably, the nozzle has a pressure rod inside, and a head is provided at the end of the pressure rod. A return spring is connected between the pressure rod and the head. The head is frustum-shaped and has a groove. A travel rail is provided in the groove and the travel rail is connected to a baffle provided on the end face of the nozzle.

[0016] By adopting the above technical solution, when the liquid pressure is high, the top head is pushed out, the travel rail slides along the slide groove, the baffle opens, and the spray area of ​​the nozzle is increased. When the pressure is low, under the action of the second return spring, the top head returns to its original position, the travel rail slides along the slide groove, the baffle contracts, the spray area is reduced, the contact area with the foaming net of the foam generator is reduced, and the foaming quality is improved.

[0017] Preferably, the nozzle is provided with a range-extending slit.

[0018] By incorporating a range-extending slit, the high-pressure airflow is used to increase the equipment's head.

[0019] Preferably, the spray gun is equipped with a hook, the liquid pipeline is equipped with a trigger, and the gas filling port is equipped with a pneumatic knob.

[0020] The spray gun is equipped with a hook for easy hanging, a trigger controls the liquid flow, and a pneumatic knob controls the gas flow.

[0021] Preferably, the pressurization pipeline is equipped with a solenoid valve, and the housing is equipped with an electric pump electrically connected to the solenoid valve.

[0022] The gas tank, water tank, and washing liquid storage pipe are pressurized by an electric pump and a solenoid valve.

[0023] The beneficial effects of the above-described technical solution of the present invention are as follows:

[0024] 1. This invention is designed with two gas paths. One path mixes gas with water and washing liquid to form foam in a foam generator. The other path connects to a nozzle, which is equipped with a range-extending slit to increase the equipment's lift using high-pressure airflow.

[0025] 2. This invention is equipped with an air storage chamber and uses a rotating disc to add air to the foam, thereby improving foaming efficiency. The rotating disc adopts a slit-type exhaust design, which ensures uniform air addition and allows for the time interval for the washing mixture to form a water film on the foaming net of the foam generator, thereby increasing the water film formation speed and further improving the foaming quality.

[0026] 3. The nozzle of the present invention is provided with a pressure rod. When the pressure of the mixed liquid is high, the rod is pushed out and the baffle opens, increasing the spray area of ​​the nozzle. When the pressure of the mixed liquid is low, the rod is reset and the baffle contracts, reducing the spray area and the contact area with the foaming net of the foam generator, thereby improving the foaming quality.

[0039] Example

[0040] like Figures 1-3 As shown in the figure, this embodiment of the present invention provides a water-liquid-gas ratio adjustable foam machine, including a housing 1 and a spray gun 4.

[0041] The housing 1 is equipped with an air storage tank 5, a water storage tank 6, and a detergent storage tank 7. Each of the air storage tank 5, water storage tank 6, and detergent storage tank 7 is connected to a pressurization pipe 8 and an output pipe.

[0042] like Figures 4-6 As shown, the spray gun 4 includes a gas pipe 19 and a liquid pipe 21 connected to the output pipe, a nozzle gas supply pipe 15 and a foam generating gas supply pipe 25 connected to the gas pipe 19, a liquid supply pipe 22 connected to the liquid pipe 21, a nozzle 24 connected to the liquid supply pipe 22, a foam generator 34 disposed at the end of the nozzle 24, and a nozzle 16 disposed at the end of the foam generator 34. The nozzle gas supply pipe 15 is connected to the nozzle 16. The foam generating gas supply pipe 25 is equipped with a manual adjustment screw 14 and a pressure regulating valve 35.

[0043] like Figures 1-3 As shown, the output pipeline includes a gas output pipeline 3 and a mixed liquid output pipeline 2. The end of the spray gun 4 is provided with a gas filling port 11 and a mixed liquid filling port 18. The gas output pipeline 3 is connected to the gas pipeline 19 through the gas filling port 11, and the mixed liquid output pipeline 2 is connected to the liquid pipeline 21 through the mixed liquid filling port 18.

[0044] The mixed liquid output pipe 2 connects to the water storage tank 6 and the washing liquid storage tank 7. The gas output pipe 3 connects to the gas storage tank 5, which stores gas. The water storage tank 6 stores water, and the washing liquid storage tank 7 stores washing liquid. Gas, water, and washing liquid are supplied to the gas storage tank 5, water storage tank 6, and washing liquid storage tank 7 respectively through the pressurization pipe 8, and then output from the output pipe. The output gas enters the gas pipe 19, which connects to the nozzle gas supply pipe 15 and the foam generating gas supply pipe 25. The output water and washing liquid enter the liquid pipe 21 and reach the nozzle 24. The gas in the foam generating gas supply pipe 25 and the mixed liquid sprayed from the nozzle 24 enter the foam generator 34 to form foam, which is then sprayed from the nozzle 16.

[0045] As a preferred embodiment of this invention, such as Figures 5-7 As shown, the gas pipeline 19 has a gas storage chamber 23 at its end, and the liquid delivery pipeline 22 passes through the gas storage chamber 23. A rotating disc 20 is rotatably connected to the liquid delivery pipeline 22, and an exhaust slit is inclined on the rotating disc 20.

[0046] The gas in the gas pipe 19 reaches the gas storage chamber 23. The gas pushes the rotating disc 20 to rotate through the exhaust slit, and blows the foam generator 34.

[0047] As a preferred embodiment of this invention, such as Figure 6 and Figure 8 As shown, the infusion pipeline 22 is provided with a positioning hole, the foam generating gas pipeline 25 is provided with an air hole, and the pressure regulating valve 35 includes a rod 29 disposed between the positioning hole and the air hole, and a return spring 30 connecting the rod 29 and the positioning hole. The upper part of the rod 29 has a hollow structure.

[0048] Rotate the manual adjustment screw 14 to introduce gas. When the gas pressure is high, press down the rod 29. The gas enters the gas storage chamber 23 through the hollow structure on the rod 29. When the gas pressure is low, the rod 29 rises under the action of the return spring 30, and the amount of gas passing through the gas delivery pipe 25 is small.

[0049] As a preferred embodiment of this invention, such as Figure 6 , Figure 8 , Figure 10 As shown, the nozzle 24 has a pressure rod 31 inside, and a head 28 is provided at the end of the pressure rod 31. A return spring 32 is connected between the pressure rod 31 and the head 28. The head 28 is frustum-shaped and has a groove 33. A travel rail 26 is provided in the groove 33. The travel rail 26 is connected to a baffle 27 provided on the end face of the nozzle 24.

[0050] When the liquid pressure is high, the top head 28 is pushed out, the travel rail 26 slides along the slide groove 33, and the baffle 27 opens, increasing the spray area of ​​the nozzle 24. When the pressure is low, the top head 28 returns to its original position under the action of the return spring 32, the travel rail 26 slides along the slide groove 33, and the baffle 27 contracts, reducing the spray area and the contact area with the foaming net of the foam generator 34, thereby improving the foaming quality.

[0051] As a preferred embodiment of this invention, such as Figure 3 As shown, the nozzle 16 is provided with a range-extending slit, which increases the equipment's head by means of high-pressure airflow.

[0052] As a preferred embodiment of this invention, such as Figure 3 As shown, the spray gun 4 is equipped with a hook 13, the liquid pipe 21 is equipped with a trigger 17, and the gas inlet 11 is equipped with a pneumatic knob 12. The hook 13 facilitates hanging the spray gun 4, the trigger 17 controls the liquid flow rate, and the pneumatic knob 12 controls the gas flow rate.

[0053] As a preferred embodiment of this invention, such as Figure 2 As shown, a solenoid valve 9 is installed on the pressurization pipeline 8, and an electric pump 10 electrically connected to the solenoid valve 9 is installed inside the housing 1. The electric pump 10 and the solenoid valve 9 pressurize the air tank 5, the water tank 6, and the washing liquid storage pipe.

[0054] How to use this invention:

[0055] 1. Pulling the trigger 17 pressurizes the water tank 6 and the detergent storage tank 7 through the pressurization pipe 8. The water in the water tank 6 and the detergent in the detergent storage tank 7 pass through the mixed liquid output pipe 2, the liquid pipe 21 and the delivery pipe 22 in sequence to reach the nozzle 24 and spray it into the foam generator 34. When the liquid pressure in the delivery pipe 22 is high, the top head 28 is pushed out, the travel rail 26 slides along the slide groove 33, and the baffle 27 opens to increase the spray area of ​​the nozzle 24. When the liquid pressure in the delivery pipe 22 is low, the top head 28 is reset under the action of the return spring 22, the travel rail 26 slides along the slide groove 33, and the baffle 27 retracts to reduce the spray area.

[0056] 2. Rotate the pneumatic knob 12 to pressurize the gas tank 5 through the pressurization pipe 8. The gas in the gas tank 5 passes through the gas output pipe 3 and the gas pipe 19 in sequence. In the gas pipe 19, it is divided into two paths. One path goes through the nozzle gas delivery pipe 15 to the nozzle 16, and the other path goes through the foam generation gas delivery pipe 25 to the gas storage chamber 23. The gas pushes the rotating disc 20 to rotate through the exhaust slit, which blows the foam generator 34. The manual adjustment screw 14 and the pressure regulating valve 35 work together to control the flow rate of the gas in the foam generation gas delivery pipe 25.
