Description

Technical Field

[0001] The utility model relates to the field of car washers, in particular to a multi-pipeline spray washing cantilever for a car washer. Background Art

[0002] With the sustained rapid growth of my country's economy and the continuous improvement of people's living standards, the number of cars has continued to increase, and people have also put forward new requirements for car washing. Not only must the car be washed cleanly and quickly, but it must also follow the principle of water conservation. Automatic car washing systems have also quickly emerged, mainly divided into traditional brush washing and contactless washing that has emerged in recent years. Although brush washing is more thorough, it takes a long time to clean and will cause certain damage to the car paint. Contactless cleaning technology has the advantages of no need to wipe and avoid scratching the car paint. However, the overall length of the single cantilever and double-sided cantilever on the market is relatively long, the overall structure is large, and the cost is high. It is not suitable for assembly and car washing in small venues. The overall length of the single cantilever and double-sided cantilever is relatively long, and there is a risk of collision between the cantilever and the side of the car. At the same time, the overall length is relatively long, which makes the entire cleaning process use more water. Utility Model Content
