DETAILED DESCRIPTION

In order to make objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to drawings, and it is obvious that embodiments to be described are some, but not all embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by ordinary skilled persons in the art without creative labor are within a scope of protection of the present application.


Referring to FIGS. 8 and 9, the wiper arm nozzle in the prior art adopts a point-spraying structure, and the water sprayed from the wiper arm nozzle presents a columnar form, and there is a large gap among water columns, which will cause the wiper arm to dry scrape during a swing process and damage to the glass.


As shown in FIG. 1, an embodiment of the present application provides a wiper arm nozzle 100 which includes a nozzle body 110, a mounting portion 120, and a deflector 130. The wiper arm nozzle 100 is composed of three components, with a simple process and few parts, which can reduce manufacturing and labor costs.


Referring to FIGS. 1 to 4, the nozzle body 110 is provided with a water inlet 111, the mounting portion 120 is provided on the nozzle body 110, an interior of the mounting portion 120 being hollow forms a mounting cavity, and a bottom of the mounting cavity communicates with the water inlet 111. A first opening 121 and a second opening 122 are respectively formed at two ends of the mounting portion 120; and the deflector 130 is inserted into the mounting cavity and is partially located at the first opening 121 and the second opening 122. A first runner 131 and a second runner 132 are defined on the deflector 130, the first runner 131 forms a first water outlet at the first opening 121, and the second runner 132 forms a second water outlet at the second opening 122; wherein the first runner 131 and the second runner 132 are connected with a self-excited runner 140, and the first runner 131 gradually widens in a direction adjacent to the first water outlet, and the second runner 132 gradually widens in a direction adjacent to the second water outlet.


When the wiper arm nozzle 100 needs to spray water to the glass, water having a certain pressure enters the interior of the mounting cavity from the water inlet 111, and is sprayed out from the first water outlet and the second water outlet through the first runner 131 and the second runner 132 respectively under an action of the deflector 130. Since the first opening 121 and the second opening 122 are at either end of the mounting portion 120, correspondingly, directions of a water flow sprayed respectively from the first water outlet and the second water outlet are opposite. Since the first runner 131 is connected with the self-excited runner 140 in the direction adjacent to the first water outlet, and the second runner 132 is connected with the self-excited runner 140 in the direction adjacent to the second water outlet, the water sprayed from the first water outlet and the second water outlet will diffuse in a fan shape that swings left and right toward either end, so that particles of the water are uniformly distributed in an S-shape in a fan section area. Therefore, an area of water sprayed on the glass is large, and a blank area is small, thus preventing the wiper from dry scraping and damaging the glass.


Referring to FIGS. 12 and 13, in one embodiment, the self-excited runner 140 includes a shunt portion 141 provided on the deflector 130, two shunt blocks 1411 facing each other are provided inside the shunt portion 141, a first deflecting portion 1413 is formed between the two shunt blocks 1411 and an inner wall of the shunt portion 141, and a second deflecting portion 1412 is formed between the two shunt blocks 1411, wherein the second deflecting portion 1412 gradually widens in the direction adjacent to the first water outlet. Two of the first deflecting portions 1413 are located on either side of the second deflecting portion 1412, and water flowing from two of the first deflecting portions 1413 and water flowing from the second deflecting portion 1412 merge into the first water outlet or the second water outlet, and present a cross-swaying state under an action of the inner wall of the first water outlet or the second water outlet.


In some specific embodiments, an included angle between fan-shaped water flows sprayed from the first water outlet and the second water outlet may reach 140°-180°. As such, the coverage area of the water flow becomes larger.


When the deflector 130 is inserted into the mounting cavity, portions of the deflector 130 on either side of the first runner 131 and the second runner 132 are fitted to an inner wall of the mounting portion 120 to form a first water outlet channel and a second water outlet channel. It should be understood that the first runner 131 and the second runner 132 are groove structures on a surface of the deflector 130. When the deflector 130 is adjacent to the inner wall of the mounting portion 120, the water flow will flow through a guidance of the first water outlet channel and the second water outlet channel, so that the water can be uniformly sprayed at the first water outlet and the second water outlet, wherein a flow direction of the first runner 131 is opposite to that of the second runner 132. As such, spaying is performed from two directions, and the coverage area is larger.


As shown in FIG. 4, in one embodiment, the first runner 131 and the second runner 132 are on the same side of the deflector 130. The first runner 131 and the second runner 132 jointly use the same water inlet channel, and the water flow enters the water inlet channel, then is dispersed at an intersection of the first runner 131 and the second runner 132 and enters the first runner 131 and the second runner 132, respectively, and then is sprayed from the first water outlet and the second water outlet.


As shown in FIGS. 5 and 6, in another embodiment, the first runner 131 and the second runner 132 are on either side of the deflector 130. The first runner 131 and the second runner 132 respectively adopt two independent water inlet ends, and the water flow enters the first runner 131 and the second runner 132 from two of the water inlet ends, respectively, and then is sprayed out from the first water outlet and the second water outlet. Compared with the first runner 131 and the second runner 132 defined on the same side of the deflector 130, and the first runner 131 and the second runner 132 defined on either side of the deflector 130 here reasonably utilizes a space of the deflector 130, so that a structure of the deflector 130 is smaller.


In the present application, both the first runner 131 and the second runner 132 include two runner walls 133 facing each other, wherein the two runner walls 133 gradually move closer to the interior of the mounting cavity from the first water outlet or the second water outlet. The two runner walls 133 intersect with each other. In some specific shapes, the first runner 131 and the second runner 132 are in a trapezoidal state at the first opening 121 and the second opening 122. It should be noted that, after the deflector 130 and the mounting portion 120 are mounted and sealed, under the action of the self-excited runner 140, the water flow sprayed out from the first water outlet and the second water outlet can form a flat fan shape, and the water flow swings left and right, and the particles of the water are evenly distributed in the S-shape in the fan section area, so that the sprayed water flow is more uniform.


Referring to FIGS. 1 to 3, in one embodiment, a limiting block 123 is provided on the mounting portion 120, and the limiting block 123 is located below the second opening 122. When the deflector 130 is inserted into the mounting cavity, the limiting block 123 abuts against the deflector 130. In order to prevent the deflector 130 from being easily loosened due to an action of water flow pressure when inserted into the mounting cavity and affecting a spaying effect, the deflector 130 and the mounting portion 120 are interference-fitted. The mounting portion 120 and the limiting block 123 jointly limit the deflector 130 to stabilize the mounting of the deflector 130.


Further, the first opening 121 is larger than the second opening 122, and the first opening 121 forms an insertion end of the mounting portion 120. The deflector 130 is inserted into the mounting portion 120 from the first opening 121, stops moving when abutting against the limiting block 123, and at this time, the deflector 130 abuts against the limiting block 123, both side inner walls and a top inner wall of the mounting portion 120. As such, the deflector 130 is inserted from the first opening 121, so that the mounting of the wiper arm nozzle 100 is more convenient.


Furthermore, the limiting block 123 is concave to form a snap-fit portion 124, the snap-fit portion 124 is a groove, and the deflector 130 is provided with an extension section 134, and the extension section 134 can be inserted into the snap-fit portion 124. A interference fit between the extension section 134 and a notch of the groove, that is, when the extension section 134 is inserted into the groove, the extension section 134 is fitted to an inner wall of the groove, so that when the deflector 130 is pressed into place in the mounting portion 120, the water flow can be prevented from flowing out of a gap between the groove and the deflector 130, avoiding affecting the spraying effect of the nozzle.


As shown in FIG. 1, in one embodiment, the mounting portion 120 is a part of the nozzle body 110, and the mounting portion 120 and the nozzle body 110 are both plastic parts, and are integrally formed by injection molding of the plastic parts, which facilitates manufacturing of the nozzle body 110. At the same time, a connection between the mounting portion 120 and the nozzle body 110 is smooth, avoiding a large gap between the mounting portion 120 and the deflector 130 when the deflector is inserted, so that the deflector 130 has good sealing when the deflector 130 is inserted, and a spaying efficiency is ensured.


The wiper arm nozzle 100 of the present application is composed of a nozzle body 110, a deflector 130, and a mounting portion 120, and has few parts, a simple structure, and is easy to mount; the mounting portion 120 is integrally connected to the nozzle body 110, and the deflector 130 is interference-fitted with the mounting portion 120, making the structure of the nozzle compact and reducing manufacturing and labor costs.


Referring to FIGS. 7, 10, and 11, a second aspect of the present application provides a wiper 200 including a wiper arm 210 and the wiper arm nozzle 100 according to any one of the above embodiments, the wiper arm nozzle 100 is provided on the wiper arm 210, and the first water outlet and the second water outlet respectively face two opposite directions of the wiper arm 210. Since the water sprayed from the first water outlet and the second water outlet is in a swaying fan shape state, and the wiper arm nozzle 100 of the wiper 200 sprays from two directions, the coverage area is large and the spraying is uniform, which facilitates wiping by the wiper arm 210. Due to a large coverage area and uniform spraying of the wiper arm nozzle 100, the wiper arm 210 will not throw water far away when rotating, thus avoiding shielding the driver's sight.


A third aspect of the present application provides an automobile including two wipers 200 as described in the above embodiment. The two wipers 200 are rotatably arranged on the automobile, and are used for spraying water to wipe the glass of the automobile.


As the automobile has the wiper 200 of the above-described embodiment, the automobile has the above-described beneficial effects that the wiper 200 can achieve, and will not be repeatedly described here.


Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; while the present application has been described in detail and with reference to the foregoing embodiments, it will be understood by a person skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and these modifications or substitutions do not depart from a spirit and scope of corresponding technical solutions of the embodiments of the present application.
