Washer nozzle
A washer nozzle ( 1 ) includes a nozzle body ( 2 ), a nozzle tip ( 11 ) which is mounted within the nozzle body ( 2 ), and a nozzle holder ( 15 ) having a head portion ( 9 ) for storing the nozzle body ( 2 ) and also has a supply portion ( 10 ) for supplying a cleaning liquid. The nozzle body ( 2 ) has a partitioning plate ( 4 ) configured to partition the spray orifice into two-tiered parts, and also has a guide portion ( 3 ) for guiding liquid spray. The nozzle body ( 2 ) of the washer nozzle ( 1 ) is configured so that the relative angle between upper liquid spray and lower liquid spray can be changed by making the length (a) of a guide region variable, the guide region extending in the direction of the center axis (c) of the nozzle body from the front end surface of the partition plate to the front end surface of the guide portion ( 3 ).
1. A washer nozzle comprising: a nozzle body; a nozzle tip to be mounted in the interior of the nozzle body; and a nozzle holder having a head portion configured to store the nozzle body and a supply portion configured to supply cleaning liquid,
the nozzle body including: a spray orifice configured to spray the cleaning liquid; a partitioning plate configured to partition the spray orifice into two-tiered parts; and a guide portion configured to be projected from an outer peripheral portion of the spray orifice of the nozzle body along the direction of a center axis of the nozzle body in order to guide a liquid spray sprayed from the spray orifice,
wherein the guide portion is provided with a variable length part configured to change a length of the guide portion along a direction of the center axis of the nozzle body, whereby by changing the length of the guide portion, a length of a guide area from a distal end surface of the partitioning plate to a distal end surface of the guide portion is made variable,
wherein the variable length part comprises at least one slit formed on an outer peripheral surface of the guide portion, and is formed so as to allow the guide portion to be cut along one slit of said at least one slit, and
wherein the guide portion comprises inner guide surfaces facing each other that have a constant inner separation between them along the entire length of the guide portion, including the guide area.
2. The washer nozzle according to claim 1 , wherein the partitioning plate for partitioning the spray orifice of the nozzle body into the two-tiered portions includes front and back surfaces parallel to each other.
3. The washer nozzle according to claim 1 , wherein the guide portion includes a pair of guide plates projecting so as to extend from upper and lower positions of the outer peripheral portion of the spray orifice along the direction of the center axis, and a length a of the guide area is within a range of 0 mm<a≦0.2 mm.
4. The washer nozzle according to claim 1 , wherein said at least one slit comprises a plurality of slits spaced apart at intervals along the direction of the center axis.
5. The washer nozzle according to claim 1 , wherein said at least one slit is constituted by a plurality of slits that are formed in each of the pair of guide plates and are spaced apart at intervals along the direction of the center axis.
6. A washer nozzle comprising: a nozzle body; a nozzle tip to be mounted in the interior of the nozzle body; and a nozzle holder having a head portion configured to store the nozzle body and a supply portion configured to supply cleaning liquid,
the nozzle body including: a spray orifice configured to spray the cleaning liquid; a partitioning plate configured to partition the spray orifice into two-tiered parts; and a guide portion configured to be projected from an outer peripheral portion of the spray orifice of the nozzle body along the direction of a center axis of the nozzle body in order to guide a liquid spray sprayed from the spray orifice,
wherein the guide portion is provided with a variable length part configured to change a length of the guide portion along a direction of the center axis of the nozzle body, whereby by changing the length of the guide portion, a length of a guide area from a distal end surface of the partitioning plate to a distal end surface of the guide portion is made variable,
wherein the variable length part comprises at least one slit formed on an outer peripheral surface of the guide portion, and is formed so as to allow the guide portion to be cut along one slit of said at least one slit;
wherein the guide portion includes a pair of guide plates projecting so as to extend from upper and lower positions of the outer peripheral portion of the spray orifice along the direction of the center axis, and wherein said at least one slit is constituted by at least one slit formed in each of the pair of guide plates, and
wherein the guide plates comprise inner guide surfaces facing each other that have a constant inner separation between them along the entire length of the guide portion, including the guide area.
7. The washer nozzle according to claim 6 , wherein the inner guide surfaces are flat guide surfaces.
8. The washer nozzle according to claim 6 , wherein the partitioning plate for partitioning the spray orifice of the nozzle body into the two-tiered portions includes front and back surfaces parallel to each other.
9. The washer nozzle according to claim 6 , wherein the guide plates project so as to extend from upper and lower positions of the outer peripheral portion of the spray orifice along the direction of the center axis, and a length a of the guide area is within a range of 0 mm<a≦0.2 mm.
10. The washer nozzle according to claim 6 , wherein said at least one slit comprises a plurality of slits spaced apart at intervals along the direction of the center axis.
11. The washer nozzle according to claim 6 , wherein said at least one slit is constituted by a plurality of slits that are formed in each of the guide plates and are spaced apart at intervals along the direction of the center axis.
