[0035] As shown in FIGS. 1 and 2, the wiper arm 10 is further provided with a hose 400 and a nozzle 500, and the hose 400 extends along the wiper arm body 100, of which one end is connectable to a cleaning fluid supply container or another supply channel connected to the supply container, and the other end is (for example, but not limited to, detachably) connected to the nozzle 500 to supply a cleaning fluid to the nozzle 500. The nozzle 500, used for spraying a cleaning fluid to a windshield, is connected to an extension section 220 of the wiper arm end piece 200, the extension section 220 is provided on the outward swing side B of the wiper arm 10, and the nozzle 500 is connected to the extension section 220 towards the return side Z. It should be noted that a wiping area of a wiper comprising the wiper arm 10 and a wiper blade on a windshield is defined by a return pause position close to the bonnet of the vehicle and a outward swing pause position away from the bonnet of the vehicle, and, correspondingly, the outward swing side B refers to the side of the wiper arm 10 close to an outward swing pause position, wherein, as shown in FIG. 1, the outward swing side B is indicated as the right side of the wiper arm 10; the return side Z refers to the side of the wiper arm 10 close to the bonnet of the vehicle, and, as shown in FIG. 1, the return side is indicated as the left side of the wiper arm 10.

[0036] In an example, a snap connection is established between the nozzle 500 and the extension section 220. Specifically, as shown in FIGS. 3 and 4, the extension section 220 extends towards the outward swing side B, and comprises a middle section 221, and edge sections 222 and 223 on either side of the middle section 221; the nozzle 500 comprises a nozzle body 510, an accommodating groove 521, an accommodating groove 522, and a hose joint 530, wherein the accommodating groove 521, the accommodating groove 522, and the hose joint 530 all protrude from one side of the nozzle body 510; the notches of the accommodating groove 521 and the accommodating groove 522 face each other, and the edge section 222 and the edge section 223 of the extension section 220 are insertable into the accommodating groove 521 and the accommodating groove 522, respectively; the hose joint 530 is detachably connected to the hose 400.

[0037] Preferably, as shown in FIG. 4, the edge section 222 and the edge section 223 of the extension section 220 sink relative to the middle 5 section 221, so that after the nozzle 500 is connected to the extension section 220, the upper surface of the nozzle 500 is substantially flush with the upper surface of the middle section 221, thereby improving the aesthetic appeal of the wiper arm 10.

[0038] In another example, as shown in FIGS. 5 and 6, the extension section 220 comprises a middle section 221, and the edge sections 222 and 223 on either side of the middle section 221, wherein the middle section 221 extends towards the outward swing side B, while the edge sections 222 and 223 are bent towards the bottom side of the middle section 221 and extend towards each other along the bottom surface of the middle section 221; the nozzle 500 comprises a nozzle body 510, an accommodating groove 521, an accommodating groove 522, and a hose joint 530, wherein the accommodating groove 521, the accommodating groove 522, and the hose joint 530 all protrude from one side of the nozzle body 510; the notches of the accommodating groove 521 and the accommodating groove 522 face away from each other, and the edge section 222 and the edge section 223 of the extension section 220 are insertable into the accommodating groove 521 and the accommodating groove 522, respectively; the hose joint 530 is detachably connected to the hose 400.

[0039] Preferably, as shown in FIGS. 1, 4 and 6, after the nozzle 500 is snapconnected to the extension section 220, the hose joint 530 is shielded by the extension section 220, thereby improving the aesthetic appeal of the wiper arm 10.

[0040] Preferably, as shown in FIGS. 2, 3, 5, and 7, at least one of the edge section 222 and the edge section 223 is provided with a protrusion 224, correspondingly at least one of the accommodating groove 521 and the accommodating groove 522 is provided with an opening 523, and the nozzle 500 is deformable to make the protrusion 224 snap into the opening 523, thereby preventing the nozzle 500 from falling off the extension section 220 easily. Herein, the protrusion 224 may be triangular or have any other shape.

[0041] As shown in FIGS. 5 and 7, the nozzle body 510 may further comprise a flow channel 511 for a cleaning fluid, and the flow channel penetrates the nozzle body 510. In addition, the hose joint 530 is in fluid communication with the nozzle body 510, so that a cleaning fluid can flow into the nozzle body 510 from the hose joint.

[0042] Preferably, as shown in FIG. 9, at least one part of the extension section 220 is deflected downwards by an angle towards the windshield side relative to the upper surface of the hook 210.

More preferably, the above-mentioned deflection angle corresponds to an installation tilt angle of the windshield, so that when the wiper is installed on the windshield of a vehicle, in the direction of observation by a driver in the vehicle, the nozzle 500 and the extension section 220 block the driver's path of observation as little as possible, which allows a reduction of interference by the wiper to the driver to ensure driving safety.

[0043] It should be noted that although it is shown in the preceding example that the nozzle 500 and the extension section 220 are located on the outward swing side B of the wiper arm 10, and that the nozzle 500 is connected to the extension section 220 towards the return side Z, it is understandable that the nozzle 500 and the extension section 220 may also be located on the return side Z of the wiper arm 10, and that the nozzle 500 is connected to the extension section 220 towards the outward swing side B.

[0044] According to an embodiment of the present application, the arrangement of a nozzle on the wiper arm ensures that a cleaning fluid is quickly wiped off, the driver is given a clear field of vision, and the cleaning fluid usage may also be reduced.

[0045] According to another aspect of the present application, it further relates to a wiper, comprising a wiper arm 10 as described above and a wiper blade, wherein the wiper blade is held by the wiper arm end piece 200 of the wiper arm 10.

[0046] According to yet another aspect of the present application, it further relates to a vehicle, comprising a wiper arm 10 as described above, or a wiper as described above.

[0047] The present application, instead of being limited to the abovedescribed structures, may also have other variants. Although the present invention has already been described by means of a limited number of embodiments, those skilled in the art could, drawing benefit from this disclosure, design other embodiments which do not depart from the scope of protection of the present invention disclosed herein. Thus, the scope of protection of the present invention should be defined by the attached claims alone.
