（Drop）The electronic device in inside can be reached, so as to easily cause charger to damage.Therefore, there is an urgent need for a kind of new scheme
To solve the problem.
The content of the invention
The utility model is exactly for technical problem present in prior art, there is provided a kind of electric car charger air inlet
Water-tight device, it is the technical scheme smart structural design, compact, be effectively protected the charging of the inside by rainwater gear outside
Device.
To achieve these goals, the technical solution of the utility model is as follows, and a kind of electric car charger air inlet is prevented
Water installations, it is characterised in that the water-tight device includes upper shell and lower house, and the upper shell and lower house are buckled in one
Rise, air inlet and air channel are provided with the upper shell, air inlet and air channel are provided with the lower house.
As a kind of improvement of the present utility model, the air inlet on the upper shell is arranged to multiple, on the lower house
Air inlet be arranged to multiple.
As a kind of improvement of the present utility model, the air channel on the upper shell is arranged to oblique air channel, the lower house
On air channel be arranged to oblique air channel, the oblique air channel of the upper shell and the oblique air channel both direction of lower house are opposite.
As a kind of improvement of the present utility model, water bar is provided with the lower house, the water bar is located at lower casing
Body bottom, it is 3-5mm with lower house upper air duct distance, is highly 5-8mm.
As a kind of improvement of the present utility model, apopore, the quantity of the apopore are additionally provided with the lower house
To be multiple, the both sides of lower house are separately positioned on, apopore is 3-5mm apart from lower house distance from bottom, coordinates water bar to make product
Water flows out charger.
As a kind of improvement of the present utility model, the air inlet is arranged to vertical strip.
Relative to prior art, the utility model has the following advantages that, 1）The technical scheme global design is ingenious, structure is tight
Gather；2）Because charger fan is when containing moisture in the technical scheme（Drop）Air suction charger lead to air inlet after, profit
The characteristics of big with inertia and weight the ratio air of moisture content, by the angle and length that rationally design wind passage so that air is logical
After crossing two air channels, the moisture content of wherein most can be blocked on wind path wall by two oblique and mutual reverse air channels, when tired
Because Action of Gravity Field drops to bottom after accumulating to certain volume, there is the water bar of a stop water bottom, prevents bottom water from flowing
Enter charger internal, but charger is flowed out by delivery port and using delivery port and the space that bottom is left, and air can
Smoothly to reach charger internal relatively to reach the purpose of electronic unit radiating.So as to avoid and reduce charger due to water inlet
And damage；3）The technical scheme cost is relatively low, is easy to large-scale popularization and application.

Embodiment：
In order to deepen, to understanding of the present utility model, the present embodiment to be described in detail below in conjunction with the accompanying drawings.
Embodiment 1：Referring to Fig. 1-Fig. 8, a kind of water-tight device of electric car charger air inlet, the water-tight device includes
Upper shell 1 and lower house 2, the upper shell 1 and lower house 2 are fastened togather, and the He of air inlet 11 is provided with the upper shell 1
Air channel 12, is provided with air inlet 11 and air channel 12 on the lower house, and the air inlet on the upper shell is arranged to multiple, described
Air inlet on lower house is arranged to multiple；Air channel on the upper shell is arranged to oblique air channel, the wind on the lower house
Road is arranged to oblique air channel, and the oblique air channel of the upper shell and the oblique air channel both direction of lower house are opposite.Enclosure interior
There is provided for two oblique and reverse air channels mutually, connect with air vent, the length and angle in the air channel and the width of air vent
Degree is related, and windage is small and the good balance of dash effect to reach, and horizontal length is in 13-20mm, and angle is according to air channel length and logical
Air ports size adjusts, it is desirable in any angle of ventilating opening to can't see any electronic unit inside charger shell, avoids
With reduce infringement caused by charger leak.Referring to Fig. 3-Fig. 6, water bar 13, the dash are provided with the lower house
Bar is located at the bottom of lower house 1, is 3-5mm with lower house upper air duct distance, is highly 5-8mm, can be internally formed with recharger
One water reserve, it is easy to the timely exclusion of ponding;Referring to Fig. 3-Fig. 6, be additionally provided with apopore 14 on the lower house, it is described go out
The quantity in water hole is multiple, is separately positioned on the both sides of lower house, and apopore is 3-5mm apart from lower house distance from bottom, is coordinated
Water bar makes ponding flow out charger.Referring to Fig. 1, the air inlet 11 is arranged to strip, on the upper shell and lower house
Square opening 15 is additionally provided with, the square opening is used to place charger input, goes out electric wire.
Operation principle：Referring to Fig. 1-Fig. 8, a kind of water-tight device of electric car charger air inlet, charger ventilating fan work
