Description

Technical Field

[0001] The utility model relates to the technical field of self-service car washing, in particular to a foam uniform spraying device for self-service car washing. Background Art

[0002] In self-service car washes, the foam spraying device is an essential component of the cleaning process, and its performance directly impacts the car wash effect and user experience. However, existing self-service car wash uniform foam spraying devices still have some significant shortcomings in practical applications, particularly problems with insufficiently fine foam and uneven spraying. These issues not only affect car wash efficiency but can also damage the vehicle surface, reducing the user experience.

[0003] Existing foam spraying devices often produce large and unevenly distributed foam particles due to an improper gas-liquid mixing ratio or a single mixing method. These coarse foam particles not only have difficulty penetrating into car body crevices to remove stubborn stains, but also easily scratch the paintwork when they come into contact with the surface. This damage is particularly noticeable on high-end vehicles with sensitive surfaces. Furthermore, the uneven size of the foam particles is caused by inadequate gas-liquid mixing, which not only affects the foam's adhesion but can also significantly reduce cleaning effectiveness.

[0004] Existing foam spraying devices typically feature simple nozzle designs during the spraying process, making it difficult to achieve uniform foam coverage. Due to limitations in spray angle and range, existing nozzles often only produce dense foam coverage in certain areas, while leaving other areas with sparse foam, resulting in uneven cleaning results. This uneven spraying is particularly problematic when dealing with large vehicles or complex car body parts. It not only increases the difficulty of washing, but can also affect the overall effect due to inadequate cleaning of certain areas. Furthermore, nozzle blockage or wear can further exacerbate this problem, making the foam spray even more uneven.

[0005] Existing foam spraying devices lack intelligent adjustment capabilities during operation. Different vehicle types and levels of soiling require different foaming patterns, yet most existing devices only offer fixed foaming patterns and cannot be adjusted to suit specific cleaning needs. This means users must frequently make manual adjustments to meet varying cleaning requirements, increasing operational complexity and time costs. Especially in unusual climates like winter or rainy seasons, mud and dirt on vehicle bodies are more difficult to remove, and spraying devices lacking intelligent adjustment capabilities struggle to meet efficient cleaning requirements.

[0006] From a user experience perspective, existing foam spraying devices produce a cumbersome and time-consuming process due to their lack of fine foam and uneven spraying. Car owners often desire a quick and efficient car wash, but existing systems fail to provide a satisfactory solution. Large and unevenly distributed foam particles not only impair the cleaning effect but can also require repeated spraying of the same area, increasing labor intensity. Furthermore, for those striving for a perfect car wash, this uneven foam spraying method is undoubtedly a disappointing experience.

[0007] Therefore, how to provide a foam uniform spraying device for self-service car washing is a problem that those skilled in the art urgently need to solve. Utility Model Content
