Description

An automatic car washing machine

technical field

The utility model belongs to a car washing device, in particular to a simple water-saving automatic car washing machine.

Background technique

In recent years, in order to save water resources and improve the efficiency of car washing, automatic car washing machines have appeared in the auto service industry. The existing automatic car washing machines are roughly divided into two categories: non-contact automatic car washing machines and brush-type automatic car washing machines. Although both car washing machines have the advantages of water saving, energy saving, short time consumption and high efficiency compared with manual car washing, the number of car washing machines currently in use on the market is relatively small, mainly in some 4S shops, large car beauty shops and other places. The main reasons for installing an automatic car washing machine are: 1. The technology of domestic car washing machines is not mature enough, and the price of good quality car washing machines is relatively expensive, and the maintenance cost is high; Certain space requirements. In the first- and second-tier cities, the land is scarce, the ground price is very expensive, and the cost of living is high. Therefore, for some self-employed car wash shops, to install an automatic car wash machine, you must consider the price, equipment footprint, water and electricity usage costs, etc. In terms of problems, the existing automatic car washing machine can not meet the requirements of self-employed households, so it can not be more widely used.

In the patent No. CN105212515A "Full-automatic car washing equipment", the length of the "T"-shaped guide rail in the automatic car washing equipment is also long and takes up a lot of space; the automatic car washing equipment described in this patent adopts various sensors Continuously collect signals, transmit them to the control system to calculate the position, size and other data of the car, and then order the circular brush plate to clean the car body. The requirements are high; 2. The area of the brush plate is too small, and the cleaning efficiency for the whole vehicle is low, and the movement of the control arm is too complicated. Once the control system makes an error, the brush plate is likely to damage the body; 3. Equipment requirements There are many parts and components, and the requirements for manufacturing and processing precision are high, which makes disassembly and maintenance complicated. Therefore, the fully automatic car washing equipment described in this patent will be relatively expensive to manufacture.
