Problems solved by technology

[0003] Tunnel-type car washing machines are divided into seven brushes and nine brushes (or more). The disadvantages are: complex structure, large number of brush rollers, corresponding increase in equipment failure rate, high equipment manufacturing cost, resulting in waste of social resources; post-maintenance costs High, the replacement of a brush roller costs four to five thousand yuan; the power consumption is large, the total power of one device can reach 30 kilowatts (or higher), and the current power consumption capacity of general users cannot meet their needs; the water consumption is large, On average, about 130L of water is needed to wash a car; the equipment takes up a lot of space, and the length of a car wash site needs to be about 25m, and the width is about 4m, and the cost of renting the site is high

[0008] 2. The rotating part of the device is a cantilever component. The cantilever is long and heavy. At the same time, the entire cantilever part is connected by a chute, and it bears a live load. The trough device requires high strength, and the requirements for the base of the chute are relatively high

At the same time, the device that generates high-pressure steam has poor safety and high energy consumption

[0010] 4. The patent does not specify the control center, and it is not clear whether it is automatic control or manual control

[0012] 1. The power consumption is relatively large, the total power of the equipment reaches 19KW, and the water consumption is 120L / vehicle;

[0013] 2. According to the standard car washing mode, the car washing time is about 6 minutes, which is longer;

[0014] 3. The number of brush rollers is 3, and the mechanical structure of the vertical brush opening and closing mechanism is complicated, which increases the cost of manufacturing and maintenance;

The processing accuracy of the circular tube is very high, the processing is difficult, and the processing cost is high;

[0019] 3. The structure of the mechanical movement device is complex, the requirements for manufacturing and installation precision are high, and there are many special parts

[0021] 1. This patent is only applicable to cleaning engineering vehicles, and its scope of application is limited;

[0022] 2. Only wash the outer surface of engineering vehicles with water, and have no other functions;

[0023] 3. Use remote control to control the pump for single start and stop, without automatic control system

If you choose soft brush filaments with low hardness, there will not be much damage to the car paint film, but during the rotation of the brush plate, due to centrifugal force, the brush filaments will not scrub vertically or approximately perpendicular to the surface of the car body, but almost parallel to the surface of the car body. The surface of the car body, so that the brush wire will not fit well with the car body, and the scrubbing effect will be poor; if you choose a brush wire with a slightly higher hardness, although it can ensure a good fit between the brush wire and the body surface, it will cause car damage. Damage to the paint film

[0027] Second, because the surface of the vehicle body is not a flat surface, especially in the depression between the wheel and the fender shell, there is a large mutation. Using the ultrasonic distance measuring module to measure the distance will cause the measured distance between the brush plate and the vehicle body to be different from that of the vehicle body. The discrepancy of the actual distance will cause the malfunction of the automatic control system, which may cause damage to the car

[0028] Third, the area of ​​the brush plate is small, and it takes a long time to wash a car;

[0029] Fourth, there is a water spray device in the middle of the brush plate, and it is flushed while brushing. This scheme has inherent shortcomings. First, the bristles block the path and force of the water jet rebound, and second, due to the small scrubbing area, fresh scrubbing will appear. The surface is polluted by the muddy water thrown out by the subsequent brushing, which cannot achieve the purpose of automatic cleaning, and subsequent manual washing is required;

[0030] 2. The structure of the brush head is complicated, and many special parts need to be specially made, which is difficult to process and high in manufacturing cost;

[0031] 3. The ultrasonic transmitter receiver is installed on the back side of the disc brush, which cannot detect the distance between the car and the brush plate; the Hall element only has the distance detection function for the metal surface, and the detection distance is small. At the back of the brush plate, the distance between the brush plate and the casing under the action of the spring should be detected. If so, the brush plate with fixed bristles should be made of metal or coated with metal on the back;

[0034] 1. The structure of the patent is quite complicated, and there are many special parts. For example, there are four sets of wheel cleaning devices. The mechanical movement structure is too complicated, the manufacturing cost is high, and the maintenance cost is high;

[0035] 2. The patent only has a water spray device and no scrubbing device. In practical applications, the cleaning effect is not ideal, and a large amount of manual cleaning is required. Especially for vehicles that are driven after the rain has passed and the weather is clear, the cleaning effect is not ideal with this device alone. ;

At this time, if the distance between the cross bar and the vehicle surface continues to decrease, the touch switch will still be in contact with the vehicle's outer surface, and if the lead screw motor remains in a stopped state and does not rotate in reverse immediately, it will cause the first nozzle to contact the vehicle. Hook up

Similarly, page 0086 of P12 also has the same hidden danger

If you return to zero according to the method of 0162 on page P19, it will inevitably cause the car washing time to be extended

[0037] 4. Information such as model, brand or license plate needs to be input and stored in advance, because various brands and models on the market are very different, and new products are constantly being launched, with a huge amount of data. The workload of after-sales service is relatively large

[0039] 6. The car washing process needs to go through two processes of initial washing and fine washing. The car washing time is long and the water consumption is large.
