Description

Technical Field

[0001] The present application relates to the technical field of self-service car wash machines, and in particular to a modular self-service car wash machine and a control system thereof. Background Art

[0002] With the development of economy, the number of private cars is increasing, and the cleaning and washing of cars have also begun to penetrate into people's lives. Self-service car washing machines allow car owners to complete the car washing operation by themselves without being restricted by time and environment, which greatly solves the problems of car owners such as difficulty and high cost of car washing. Traditional self-service car washing machines generally only have the function of flushing. When the cleaning demand is greater, the operator needs to spray the washing liquid separately, which increases the workload of the operator. Therefore, a modular self-service car washing machine is needed, which has high flexibility and functional diversity. Summary of the invention

[0003] In view of the deficiencies in the prior art and in order to improve the flexibility and functional diversity of self-service car wash machines, the present application provides a modular self-service car wash machine and a control system thereof.

[0004] The above-mentioned invention objective of the present application is achieved through the following technical solutions:

[0005] A modular self-service car washing machine comprises a machine box and a door hinged to the front side of the machine box, wherein a handle and a display screen are arranged on the surface of the door;

[0006] A water treatment mechanism is disposed inside the chassis, the water treatment mechanism is connected to a cleaning mechanism, and one end of the cleaning mechanism away from the water treatment mechanism passes through a side wall of the chassis;

[0007] The top of the water treatment mechanism is connected to a washing liquid tank, the top of the washing liquid tank is provided with a water purification mechanism, and one side of the washing liquid tank is provided with a control panel.

[0008] By adopting the above technical solution, by arranging a handle and a display screen on the surface of the box door, user operation is made more convenient. The car washing water is first purified by a water purification mechanism after being input into the box, thereby providing cleaner car washing water and ensuring the car washing effect. When the user uses the cleaning mechanism to wash the car, the water and the cleaning liquid in the cleaning liquid tank flow into the water treatment mechanism respectively, the water treatment mechanism mixes the water and the cleaning liquid, and the mixed liquid enters the cleaning mechanism for user use, thereby improving the cleaning effect.

[0009] Optionally, the water purification mechanism includes a purification chamber, the inner wall of the purification chamber is provided with a filter plate, and the outer side of the purification chamber is provided with a water injection port, and the water injection port is used to input tap water into the purification chamber from an external water source;

[0010] The washing liquid tank is arranged at the bottom of the purification tank, and a feed port is opened on the outer side of the washing liquid tank;

[0011] A drain valve is provided at the bottom of the purification bin, and a liquid drain valve is provided at the bottom of the washing liquid bin.

[0012] By adopting the above technical solution, tap water is input into the purification tank through the water injection port, filtered through the filter plate, and then flows into the water treatment mechanism from the drain valve. After the washing liquid in the washing liquid tank is used up, it can be replenished through the feed port.

[0013] Optionally, the water treatment mechanism comprises a liquid storage tank, the bottom side wall of the liquid storage tank is in communication with the cleaning mechanism, and a plurality of stirring components for mixing tap water and washing liquid are arranged in parallel inside the liquid storage tank;

[0014] The water drain valve and the liquid drain valve are both communicated with the top of the liquid storage tank through pipelines.

[0015] By adopting the above technical solution, the drain valve and the liquid discharge valve are connected to the top of the liquid storage tank through a pipe. The setting of the drain valve and the liquid discharge valve facilitates the control of the flow rate and mixing ratio of the detergent and water, thereby improving the cleaning efficiency. A number of stirring components for mixing tap water and detergent are arranged in parallel inside the liquid storage tank, which can effectively mix the tap water and detergent and ensure the uniformity of the concentration of the detergent.

[0016] Optionally, the cleaning mechanism includes a hose and a high-pressure water gun, one end of the hose is connected to the bottom side wall of the liquid storage tank, and a water pump is provided at one end of the hose close to the liquid storage tank, and the other end of the hose passes through the side wall of the chassis and is connected to the high-pressure water gun;

[0017] A slot for placing the high-pressure water gun is provided at the top of the side wall of the chassis.

[0018] By adopting the above technical solution, the setting of the hose and the water gun makes the cleaning process more flexible. The user can pull the hose according to actual needs to clean different parts. The setting of the water pump provides stable pressure to ensure the cleaning effect of the water gun. A slot for placing a high-pressure water gun is provided at the top of the side wall of the chassis, which is convenient for storing and organizing cleaning tools.

[0020] The rotating rod is horizontally arranged inside the liquid storage tank, and a spiral blade is fixedly arranged on the outer wall of the rotating rod;

[0021] When the plurality of spiral blades rotate simultaneously, the mixed liquid in the liquid storage tank flows toward the water pump.

[0022] By adopting the above technical solution, the rotating rod is coaxially fixedly connected to the output end of the motor. When the detergent liquid and water in the liquid storage tank need to be stirred, the motor drives the rotating rod to rotate, and the spiral blades on the outer wall of the rotating rod rotate synchronously, thereby achieving the purpose of effectively mixing the liquid detergent and water, and at the same time making the mixed liquid in the liquid storage tank flow toward the water pump.

[0023] Optionally, a spiral channel is fixedly provided on the inner wall of the chassis, and the hose passes through the spiral channel and out of the chassis.

[0024] By adopting the above technical solution, the hose passes through the spiral channel out of the chassis. After using the high-pressure water gun, the hose is pushed into the chassis. After the hose passes through the spiral channel and enters the chassis, it will automatically coil, so that part of the hose is stored inside the chassis, which improves the cleanliness of the equipment.

[0025] The second object of the invention is achieved by the following technical solutions:

[0032] 1. By setting a handle and a display screen on the surface of the box door, the user operation is more convenient. After the car washing water is input into the box, it is first purified by the water purification mechanism, thereby providing cleaner car washing water and ensuring the car washing effect. When the user uses the cleaning mechanism to wash the car, the water and the washing liquid in the washing liquid tank flow into the water treatment mechanism respectively. The water treatment mechanism mixes the water and the washing liquid, and the mixed liquid enters the cleaning mechanism for the user to use, thereby improving the cleaning effect;
