Problems solved by technology

During the working process of the wiper device, the rubber strip rubs against the glass surface repeatedly for a long time, which will cause adverse effects on the surface of the windshield. For example, when hard objects such as stones are attached to the windshield, it is easy The surface is scratched; at the same time, the friction resistance between the rubber strip and the glass surface is relatively large, so the load on the wiper motor is large, and it is easy to cause damage to the wiper motor after long-term use, and the service life of the wiper motor is not guaranteed.
In addition, when there is dry dirt on the windshield, the dirt must be wetted by spraying water through the nozzle, and then rubbed repeatedly by the rubber strip to wipe it off. This process requires a large amount of water spray, and the effect is also not ideal

Embodiment 1

[0016] Example 1, such as figure 1 , Figure 2 and image 3 Shown, a kind of automobile wiper is made of parts such as support 1, air nozzle 2, air inlet pipe 4, screw 5 and water inlet pipe 6. Wherein the rear end of the bracket 1 is the installation part, which can be connected with the output shaft of the wiper motor (not shown in the figure). Driven by the wiper motor, the bracket 1 swings left and right with the wiper motor as the center; The remaining part is an elongated arc with the top of the arc on top. The air nozzle 2 is located in the support 1, and the air nozzle 2 is elongated and arranged in the same direction as the support 1. The two side walls of the air nozzle 2 are fixedly connected with the support 1 by screws 5.

[0017] from figure 1 , Figure 2 and image 3 It can be further seen that the air nozzle 2 is provided with an air flow channel 3 along its length direction, and the diameter of the air flow channel 3 gradually decreases from the back to the ...

Embodiment 2

[0018] Example 2, such as Figure 4 , Figure 5 As shown, in this embodiment, two airflow passages 3 are arranged side by side along its length direction on the air nozzle 2, and each airflow passage 3 is equipped with an air inlet pipe 4 and a water inlet pipe 6. The rest of the structure and implementation of this embodiment Example 1 is the same.

[0019] After the present invention is installed on the automobile in place, the front port of the airflow passage 3 is inclined upwards, and there is a certain angle between the center line of the airflow passage 3 and the windshield; an air pump and a water spray pump are installed at suitable positions on the automobile, The air pump supplies air to the intake pipe 4, and the water jet pump supplies water to the water intake pipe 6. Start the switch of the wiper motor, the bracket 1 swings left and right with the wiper motor as the center, and at the same time turn on the air pump, the high-pressure gas enters the airflow cha...

Abstract

The invention relates to a car windscreen wiper, wherein, a strip-shaped air nozzle (2) is mounted in a bracket (1), the air nozzle (2) and the bracket (1) are arranged along the same direction, an airflow channel (3) is arranged on the air nozzle (2) along the direction of the length thereof, the diameter of the airflow channel (3) is reduced gradually from the back to the front, the back end of the airflow channel (3) is communicated with an intake pipe (4), and the front port of the airflow channel (3) is arranged at the end part of the front end of the bracket (1). The car windscreen wiper adopts high-pressure gas to clean up rain, splashed mud and other dirt from the surface of windscreen, so as to avoid scratching the glass surface; meanwhile, the load of a wiper motor is lower when working, the wiper motor is not easy to be damaged and the service life can be prolonged accordingly. The car windscreen wiper can be applied to any vehicle model, even trains, ships, aircraft and other places that need the work of the wiper.

Description

technical field [0001] The invention relates to an automobile component, in particular to a jet type automobile wiper. Background technique [0002] The car will inevitably encounter special weather conditions such as rain during driving. Rain, splashed mud and other dirt adhere to the windshield, which will block the driver's sight and affect the normal operation of the driver. This requires the use of rain Scraping device for timely cleaning. A traditional wiper device is composed of brackets, rubber strips and other parts. A rubber strip is installed at the bottom of the bracket, and the bottom surface of the rubber strip is bonded to the windshield. When the wiper motor is running, the bracket swings, and the bracket drives the rubber strip to move synchronously, so that the rubber strip rubs against the surface of the windshield to drain away accumulated water and dirt. During the working process of the wiper device, the rubber strip rubs against the glass surface rep...
