Description
Technical field
The present invention relates to the wiping of glass board, more specifically, relate to windscreen wiper.
Background technology
Traditional windscreen wiper generally includes the body of rod being controlled reciprocating rotary by reversible drive motor, the described body of rod supports the flexible rain shaving blade (also referred to as sheet material) be made up of rubber or similar material, owing to being assemblied between windscreen surface and the body of rod of trammel beam system being with spring, described rain shaving blade abuts in windscreen surface, and described trammel beam system can be out of shape in the region being pressed with rain shaving blade according to the angle position of the body of rod and Windshield curvature.
Usually by means of nozzle, washing fluid is injected in cleaning glass surface being implemented Windshield or rear window, described nozzle is arranged on hood of vehicle or ventilation of vehicle grid.Be placed in the described nozzle located in a distance with glass surface to be cleaned to be difficult to regulate to obtain efficient injection.
In order to make up above-mentioned defect, in patent application FR2952884, provide a kind of windscreen wiper, described rain brush comprises elongated flexible rain shaving blade and pipe outlet, and described pipe outlet is arranged to the stratiform jet that can scatter liquid along the longitudinal direction of rain shaving blade.Described pipe outlet offsets and locates relative to rain shaving blade lip on the side of flexible rain shaving blade, indirectly cleaning liquid is uniformly scattered onto in longitudinal depressed part of lip, at the liquid ejected from injection orifice from after impact is lighted and is dispersed in the depressed part of rain shaving blade towards rain shaving blade end, described liquid arrives glass surface.
Therefore, cleaning and cleaning glass window surface operation during, cleaning liquid is only limited on the lip of windscreen wiper, ensure that the complete vision of chaufeur.
Use this rain brush to clean and mainly comprise two steps with the operation of cleaning glass window plate.
In a first step, rain brush is in dead position, and the stratiform jet of cleaning liquid spreads in most of length nozzle and rain shaving blade end separated in the depressed part of rain shaving blade lip by nozzle.
In the second step, after rain shaving blade lip rotates, cleaning is implemented.Washing fluid is in the angle formed between the end of rain shaving blade lip and glass surface in whole length of rain shaving blade, distributes regularly along rain shaving blade lip to make washing fluid.
One of them defect of these rain brush is, for enabling fluid be uniformly distributed along lip, existing and postponing between first step and second step.
Summary of the invention
One of them object of the present invention is to reduce to start pump on depressed part cleaning liquid being arranged in rain shaving blade and open rain brush for wiping, namely open rain brush from dead position to the delay between the movement of end position.
For this reason, more properly, the invention provides a kind of wiping rain brush of cleaning glass window plate, described wiping rain brush comprises flexible rain shaving blade and cleaning liquid injection system, when described wiping rain brush assembles movably around the axis substantially orthogonal with glass board, described wiping rain brush can be in dead position, in described dead position, rain shaving blade forms depressed part, it is characterized in that, injection system comprises injection orifice and the disconnector of spraywashing liquid, described disconnector comprises the first guide member and the second guide member, described injection orifice is oriented and is sprayed to disconnector by cleaning liquid, described guide member is arranged for making the cleaning liquid of injection spread to the depressed part formed by rain shaving blade when wiping rain brush is in dead position, first guide member of guiding cleaning liquid and the second guide member are respectively towards first end and the second end orientation of wiping rain brush.
Advantageously, eachly in the first guide member and the second guide member comprise ramp, each ramp comprises: first end, and described first end is oriented the cleaning liquid receiving and sprayed by injection orifice; And the second end, described the second end is oriented and is sprayed to the depressed part formed by rain shaving blade by the cleaning liquid of reception.
Advantageously, described disconnector also comprises diffusing opening, and described diffusing opening arranges the part be arranged between the first guide member and the second guide member being diffused into rain shaving blade for liquid part sprayed by injection orifice.
Advantageously, the first ramp and the second ramp connect at first end place.
Advantageously, described diffusing opening is positioned at the first end place in ramp.
Advantageously, described ramp has interior curved shape.
Advantageously, pipeline included by wiping rain brush of the present invention comprises the first straight line portion, the second sweep and the 3rd straight line portion, an end of described first straight line portion and cleaning liquid supply pipe link, and an end of described 3rd straight line portion is injection orifice.
Advantageously, wiping rain brush according to the present invention comprises retention tab, and described retention tab is used for the 3rd straight line portion of pipeline to remain in position.
The invention still further relates to a kind of wiping and washing system, described wiping and washing system comprise at least one wiping rain brush according to any one of above-mentioned requirements.
The invention still further relates to a kind of vehicle, described vehicle comprises according to wiping of the present invention and washing system or wiping rain brush.
Be to reduce according to the advantage of rain brush of the present invention and start pump and open rain brush for the delay between wiping.Use two perforates that cleaning liquid can be made to be poured into more quickly on rain shaving blade in rain brush centre.Shorter when the distance that need flow through due to liquid is arranged on rain shaving blade end than nozzle, liquid spreads on rain shaving blade more quickly.
Low pressure pump can be used according to being also advantageous in that of rain brush of the present invention.Because the distance making liquid dissemination need flow through to rain shaving blade end is shorter, spraywashing liquid can be carried out by less power when being arranged on rain shaving blade end than nozzle.The advantage of these pumps is that cost is lower and power consumption is less.
And, there are provided the optimum operation under low temperature according to the advantage of rain brush of the present invention.In fact, at low temperatures, more specifically for the temperature being less than 0 DEG C, the viscosity of cleaning liquid increases.When cleaning liquid is injected on rain shaving blade, described cleaning liquid can not spread to the other end from one end of rain shaving blade equably, thus cleaning is no longer efficient.In the present invention, the cleaning liquid distance that need flow through is shorter.For the time of identical startup pump, under identical low temperature, spread on whole rain shaving blade uniform liquid, thus keep cleaning efficiently.
The present invention be advantageous in that and obtain two strands of hydrofluidics for cleaning, a limited number of part is implemented for injection system simultaneously.In fact, injection system is run by single nozzle and disconnector, and disconnector can adopt single moulded parts form.
