Description

Technical Field

[0001] The invention relates to the technical field of pre-car washing, in particular to an intelligent automatic car washing machine. Background Art

[0002] In the profound transformation of the global new energy vehicle industry towards intelligence and networking, intelligent automatic car wash machines have become the core equipment for building a collaborative service ecosystem of "people-car-environment". The traditional manual car wash model has pain points such as low service efficiency (average daily service of a single station ≤ 70 vehicles) and insufficient operation standardization (cleaning qualification rate is only 68%), which has driven the industry to upgrade to full-process intelligence and unmanned operation.

[0003] The pre-washing work before washing the car is mainly to remove the larger particles of dirt on the surface of the car body to prevent these particles from scratching the car paint during the subsequent washing process. The pre-washing work mainly includes the following aspects:

[0004] Wash the car body: Use a high-pressure water gun to start from the roof and wash the car body from top to bottom. This way, you can use the impact force of the water flow to first wash away larger particles of dirt such as dust and sand attached to the car body. The washing order is generally the roof, front hood, side body, trunk lid, edge of the bottom of the car and other parts. Be careful not to use too high a water pressure to avoid damaging the paint. At the same time, make sure that every part is rinsed properly, especially the edges and gaps of the doors and windows.

[0005] Spray pre-wash liquid: Dilute the special car pre-wash liquid in a certain proportion, put it into a spray bottle, and then spray it evenly on the surface of the car body, including the paint, glass, wheels and other parts. The pre-wash liquid can effectively soften and decompose dirt, making it easier to wash away. When spraying, pay attention to comprehensive coverage and do not miss any place.

[0006] Soaking dirt: After spraying the pre-wash liquid, let it stay on the car body for a few minutes (usually 3-5 minutes) to allow the pre-wash liquid to fully play its role, soak and decompose the dirt. In this process, the pre-wash liquid will penetrate between the dirt and the car paint, reducing the adhesion of the dirt.

[0007] Rinse off the pre-wash liquid and dirt: After the pre-wash liquid has soaked for a certain period of time, use a high-pressure water gun to rinse the car body again to remove the pre-wash liquid and the decomposed and softened dirt. When rinsing, proceed from top to bottom to ensure that all the pre-wash liquid and dirt are rinsed off. Pay special attention to areas that are prone to dirt and grime, such as door handles, the back of rearview mirrors, and the inside of wheels.

[0008] Through the above pre-washing steps, the friction between sponges, towels and other tools and the car paint surface during the subsequent car washing process can be greatly reduced, reducing the risk of scratches on the car paint, while also improving the efficiency and cleaning effect of car washing.

[0009] The water pressure of some existing high-pressure water gun equipment cannot be adjusted or the adjustment range is limited. If the water pressure is too high, it is easy to damage the car paint, sealing strips and other parts, especially for some old vehicles or models with thinner paint. If the water pressure is too low, it cannot effectively wash away stubborn dirt such as mud, bird droppings, etc., resulting in poor pre-washing effect. An important purpose of pre-washing is to remove mud on the surface of the car body to prevent scratches on the car paint during subsequent washing. However, when flushing mud, some car washing equipment has unreasonable water flow design, which causes the mud to be washed up and then re-attached to the car body. In addition, some equipment does not have special mud collection and treatment devices, which makes it easy for the mud after cleaning to remain in the car wash area, affecting subsequent car washing work.

[0010] To this end, we propose an intelligent automatic car washing machine. Summary of the invention
