Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a wiper with a built-in cleaning nozzle comprises a swing arm 1, a wiper blade rod 2 and a wiper blade 3, wherein the swing arm 1 is fixedly connected to the front side of the wiper blade rod 2 through a connecting seat 4, a flow channel 5 for circulating cleaning liquid is arranged in the swing arm 1, the flow channel 5 is arranged along the length direction of the swing arm 1, a first liquid outlet 6 communicated with the flow channel 5 is arranged on each of the left side and the right side of the connecting seat 4, and a first nozzle 7 is arranged in the first liquid outlet 6; the front side of the swing arm 1 is respectively provided with a plurality of second liquid outlets 8 communicated with the flow channel 5, each second liquid outlet is connected with a second spray head 9, and the opening part of each second spray head 9 is provided with a sealing cover 10.

The utility model discloses in, swing arm 1 is keeping away from wiper blade 3's one end fixedly connected with base 11, and base 11 is rotatable installs in car front windshield's below, and base 11's pivot is quill shaft 12.

Correspondingly, an L-shaped channel 13 is arranged in the base 11, one end of the L-shaped channel 13 is communicated with the interior of the hollow shaft 12, and one end of the L-shaped channel 13 is communicated with the flow passage 5.

Correspondingly, a liquid inlet pipe 14 extends from outside to inside into the hollow shaft 12 and is in running fit with the inner wall of the hollow shaft 12, and the liquid inlet pipe 14 is communicated with the L-shaped channel 13 on one hand and is connected with a cleaning liquid storage tank (not shown) after being connected with a booster pump (not shown in the figure) on the other hand.

Thus, by using the hollow shaft 12 and providing the L-shaped passage 13 in the base 11, it is possible to facilitate the passage of the liquid inlet pipe 14 into the hollow shaft 12 to communicate with the flow passage 5 for supplying the cleaning liquid. Meanwhile, the liquid inlet pipe 14 is in running fit with the inner wall of the hollow shaft 12, so that the normal rotation of the hollow shaft 12, namely the normal swing of the swing arm 1, is not affected.

The utility model discloses in, the cross-section of first shower nozzle 7 is rectangle, and the interval between the lower edge of first shower nozzle 7 and the bottom surface of connecting seat 4 is 1 cm.

Therefore, on one hand, the jet orifice of the first nozzle 7 is flat, the emitting area is large, and the jet range is wide; on the other hand, the first spray head 7 and the wiper blade 3 are arranged on the same straight line as much as possible, so that when the cleaning liquid is sprayed, dirt carried by the wiper blade 3 during working can be better washed.

In the present invention, the sealing cap 10 is installed at the mouth of the second nozzle through screw-thread fit.

From this, realized the installation of closing cap 10, and when meetting sleet or frost weather, can in time open second shower nozzle 9 and spray the washing liquid to be favorable to clearing away snow or frost on the windshield before the car.

The invention is further described below with reference to the accompanying drawings:

when the cleaning liquid injection device is used, under the normal condition, a cleaning liquid injection switch is opened at the driving side in a vehicle, and under the pressurization effect of the booster pump, cleaning liquid with certain pressure enters the flow channel 5 through the liquid inlet pipe 14. Meanwhile, swing arm 1 work, drive brush piece pole 2 swings, make wiper blade 3 scrape brush car front windshield's surface, in this process, the washing liquid is finally through first shower nozzle 7, from both sides along wiper blade 3's length direction spray washing liquid, wash car front windshield, and can wash filths such as dust that wiper blade 3 carried when scrubbing, wiper blade 3 is when scrubbing car front windshield like this, can not carry filths to the car front windshield's of driving side surface, better cleaning performance has been reached, can not block the sight because of the gathering of filths, thereby potential safety hazard has been avoided.

When the automobile runs in rainy, snowy or icy weather, the sealing cover 10 is unscrewed, the two second liquid outlets 8 are opened, the cleaning liquid injection switch is opened at the driving side in the automobile, and under the pressurization effect of the booster pump, the cleaning liquid with certain pressure enters the flow channel 5 through the liquid inlet pipe 14 and is sprayed to the front windshield of the automobile through the second spray head 9, so that the snow and the frost on the surface of the front windshield of the automobile are quickened to be melted, and the automobile is convenient to use.

It should be noted that, because the first nozzle 7 sprays the cleaning liquid along the length direction of the wiper blade 3 from both sides, the cleaning liquid is directly sprayed to the surface of the front windshield of the automobile and the wiper blade 3, there is no long-distance spraying and no pressure loss, and the cleaning liquid can be guided to all places by the wiper blade 3 working synchronously immediately after being sprayed, so that the cleaning liquid can not be sprayed to the periphery of the automobile, and the interference, influence and loss caused to other surrounding vehicles and pedestrians are avoided.
