When the power supply device 32 has sufficient storage capacity, the user presses the power display button 328, and the indicator light 329 lights up; In this way, the user can judge whether the stock of the power supply device 32 is sufficient by observing whether the display light 329 is illuminated, which is intuitive and convenient, and easy to observe. Alternatively, the power display button 328 and the display light 329 can be connected to the controller, and the controller controls the light-emitting state of the display light 329 based on the power condition in the power supply device 32 when the controller responds to the pressing signal of the power display button 328 .

In this embodiment, the number of display lamps 329 is four. The four display lights 329 are arranged on the peripheral wall of the main body end 325 and are exposed outside. After the user presses the power display button 328 , the user can judge the storage capacity of the power supply device 32 according to the number of lights of the display lights 329 . Specifically, when the number of light indicators 329 is zero, it means that the power supply equipment 32 is insufficient in stock and cannot supply power to the electric car washer 10 or other load equipment; when the number of light indicators 329 is gradually increased from zero to four , which means that the stock of the power supply device 32 is gradually increasing; when the number of the display lights 329 is four, it means that the stock of the power supply device 32 tends to be saturated. It can be understood that the present application does not specifically limit the number of display lights 329, and the number of display lights 329 may be one or more than one.

It can be understood that the display light 329 can also be provided on the end surface of the main body end 325 or other positions of the power supply 32 , as long as the display light 329 can be exposed outside the power supply 32 , the present application does not specifically limit this.

It can be understood that the power display button 328 can also be arranged on the end surface of the assembly end 320 or other positions of the power supply device 32 , which is not limited in this application.

The above is not limited to the embodiments of the present application. The description of the above specific embodiments is intended to describe and illustrate the technical solution of the present application. The above specific embodiments are only illustrative and not restrictive. Anyone familiar with the technical field within the scope disclosed in the patent application, according to the technical scheme and patent concept of the patent application for equivalent replacement or change, all fall within the scope of protection of the patent application.
