Description

Technical Field

[0001] This utility model relates to the field of electric car wash brush technology, specifically to an electric water spray car wash brush. Background Technology

[0002] Currently, self-service car washes typically involve hand-wiping with a wet sponge, which is laborious and, in cold weather, leaves hands feeling icy cold. Furthermore, sponge alone cannot completely remove dirt. Additionally, many areas are inaccessible by hand, requiring tiptoeing, bending, or squatting, further increasing time and effort. For convenience, some have connected the brush head to a tap water pipe. However, this design only works in areas with running water. In outdoor settings, some designs use a water pump to draw water for both brushing and spraying. Ordinary car wash brushes typically connect the water pump to a water pipe submerged in a water tank or pool, resulting in a relatively complex structure and inconvenient use. Water pump submersion control and waterproofing are crucial, and common spray car wash brushes offer limited functionality. Therefore, we propose an electric car wash brush to address these issues.

When in use, the water flow pumped from the water pump unit 31 passes through the V-shaped cut 27 from the hollow water passage 26. Based on the change in the flow diameter, the water flow is sprayed out in a fan shape from the V-shaped cut 27. The reduced diameter accelerates the flow velocity, making the sprayed fan-shaped water flow form a larger impact wave. When in use, it is sprayed slightly away from the vehicle body. It is mainly used to rinse the sewage on the vehicle surface after washing, pushing the sewage off the outer surface of the vehicle. It can also be replaced according to the needs of car washing.
