Abstract

The invention provides a hose nozzle device for cleaning an electric vehicle. The hose nozzle device comprises a nozzle head and a nozzle handle, wherein the nozzle head comprises a spraying end and a buffer section; a horn opening is arranged in the spraying end; the horn opening is communicated with the buffer section through a straight channel; the buffer section of the nozzle head is communicated with the nozzle handle; the ratio of length to inner diameter of the straight channel is (1.27-1.5):1; the opening degree of the horn opening is determined by the inner diameter of the straight channel; the buffer section of the nozzle head is formed by successively communicating a left joint part, a straight paved path and a right joint part; the ratio of length to inner diameter of the straight paved path is (0.97-1.3):1; the inner diameter ratio of the straight paved path to the straight channel is (3.65-4):1. The hose nozzle device is made of a high-toughness metal material, is difficult to break, can be randomly bent and is simple and convenient to use; the electric vehicle is cleaned under the condition that the protecting level of all parts of the electric vehicle is not influenced; the driving safety of the electric vehicle after cleaning is ensured.

Description

【Technical field】 [0001] The invention relates to the field of electric vehicles, more specifically, to a cleaning device for electric vehicles. 【Background technique】 [0002] Traditional cars generally use high-pressure water guns for washing, but the motor and battery of electric vehicles are not sealed. If high-pressure water guns are used for cleaning, the water vapor sprayed by the water gun will adhere to the circuit connecting the motor and battery. It is prone to short circuit, which will burn out the motor and cause danger easily. Therefore, in order to meet the normal cleaning requirements of electric vehicles, it is necessary to provide a new cleaning device to effectively clean the electric vehicles normally without affecting the various components of the electric vehicle, so as to ensure the safety of the electric vehicle after cleaning. And there is no device specially for the normal cleaning of electric vehicles at present. 【Content of invention】 [0003]...
