It is proposed that the at least one nozzle unit is arranged in the mounted state at least substantially in the extension of the wiper rod of the wiper arm unit and is fastened to the wiper arm unit by means of a latching connection.

In CN104943660B, the structure of the nozzle unit locked on the wiper arm unit is relatively complex, and its main technical solution is: a wiper arm device with a wiper arm unit and at least one nozzle unit, the wiper arm unit having at least one wiper rod, which nozzle unit is provided for applying washing water to a vehicle window pane, which nozzle unit is arranged at least substantially alongside the wiper arm unit in the mounted state, characterized in that the at least one nozzle unit is arranged in the mounted state at least substantially in the extension of the wiper rod of the wiper arm unit and is fastened to the wiper arm unit by means of a snap-in connection, wherein the wiper arm unit has at least one first retaining part which is at least substantially rigid and to which the at least one nozzle unit is fixed in the mounted state, wherein the at least one nozzle unit has at least two first elastic elements between which the at least one first retaining element is latched in the mounted state.

In addition, CN206306998U discloses a wiper arm capable of spraying water, which includes a wiper arm main body, wherein the wiper arm main body or a part of the wiper arm is connected with a nozzle system through a connector; the inner cavity of the wiper arm main body is provided with an inner cavity hole and a clamping piece which are matched with the spray head system; the nozzle system is provided with an inner cavity matched with the wiper arm main body and a hook; the spray head system has at least three water outlets: a water outlet A, a water outlet B, a water outlet C and a water inlet; the hook of the spray head system is inserted into the inner cavity hole of the wiper arm main body and clamped, and the end clamping piece of the wiper arm main body is inserted into the inner cavity of the spray head system and clamped.

The CN104943660B and the CN206306998U both have the problems of complex mold structure and high preparation cost.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that the preparation cost is high to the current ability water spray windscreen wiper exists and provide a simple structure, the improved generation of being convenient for manufacturing can water spray windscreen wiper arm.

The utility model discloses the technical problem that will solve can realize through following technical scheme:

an improved water spraying wiper arm comprises a wiper arm main body and a water spraying component, wherein a water spraying component mounting side wall is arranged on the wiper arm main body, at least one flanging which is firstly turned over to a direction parallel to the wiping direction of a wiper and then is turned over to a direction perpendicular to the wiping direction of the wiper is arranged on the water spraying component mounting side wall, and at least one groove is formed; at least one sliding groove and at least one spring sheet which is turned outwards are arranged on one side wall of the cover in the water spraying component, which is close to the mounting side wall of the water spraying component; the flanging and the sliding groove and the elastic sheet respectively form one-to-one correspondence; during assembly, the turnover part which is turned over to the direction perpendicular to the wiping direction of the wiper in the turnover edge is inserted into the sliding groove, and the elastic sheet is bounced into the groove.

In a preferred embodiment of the present invention, the water spray assembly is provided with three nozzles.

Owing to adopted above technical scheme, the utility model provides a windscreen wiper arm main part and water spray component equipment mode are simple, and the structure is also simple separately, low in manufacturing cost. Meanwhile, the cover which is integrally manufactured is arranged on the water spraying assembly, so that the number of parts and the assembling process are simplified.
