Technical Field

The invention belongs to the technical field of automobile manufacturing, and particularly relates to a novel air grid structure of a washing liquid tank.

Background

Along with the development of the automobile industry, functions carried on vehicles are more and more, people pay attention to original functions of automobiles, and pay more attention to multiple attributes such as safety, comfort, convenience, science and technology.

Under the condition of no air grid design of the existing washing liquid tank, a user uses normal-temperature glass water, when the capacity is filled, under the low-temperature conditions such as winter, the liquid state of the glass water is changed into a solid state, the volume is increased, and the limit working condition that the washing tank body is cracked and damaged exists.

Disclosure of Invention

In order to solve the problems in the prior art, the invention provides an air grid structure of a washing liquid tank, which can improve the safety performance of a whole vehicle.

The invention is realized by the following technical scheme:

a novel air grid structure of a washing liquid tank comprises a washing tank body 1, a flow guide pipe 2, a washing pump 3 and a rubber sleeve 4, wherein the lower end of the flow guide pipe 2 is provided with an extension structure, the extension structure extends into the washing tank body 1, and the washing pump 3 is positioned at the lower part of the washing tank body 1 and is clamped with the washing tank body 1; the rubber sleeve 4 is positioned at the connecting position of the washing tank 1 and the washing pump 3, so that the sealing performance of the washing tank body 1 is ensured.

Preferably, the washing tank body 1 is provided with a draft tube mounting port for passing through the draft tube 2.

Preferably, a protruding structure is arranged at the position where the extending structure on the draft tube 2 is connected with the draft tube mounting port on the washing tank body 1, and is used for being clamped with the draft tube mounting port of the washing tank body 1.

Preferably, the elongated structure on the draft tube 2 extends vertically downwards along the draft tube 2, and the pipe diameter of the elongated structure is reduced by 3mm compared with that of the draft tube, so that too rapid change is avoided.

Preferably, the length of the elongated structure on the draft tube 2 below the inner upper surface of the washing tank 1 is equal to one tenth of the volume of the washing tank 1 divided by the surface area of the connection part of the washing tank 1 and the draft tube 2.

Preferably, the length of the extension structure on the guide pipe 2 under the upper surface in the washing tank body 1 is between 20mm and 30 mm.

Preferably, the space formed by the extension structure at the lower end of the draft tube 2 and the inner upper surface and the side surface of the washing tank body is an air grid structure.
