Pistol-type nozzle of gardening sprinkler

[0001] 1. Field of the Invention

[0002] The present invention relates generally to a pistol-type nozzle, and more particularly to a connection structure of a spray head and a barrel of the pistol-type nozzle, and a trigger of the pistol-type nozzle.

[0003] 2. Description of Related Art

[0004] The conventional pistol-type nozzle comprises a hand grip, a barrel extending from one end of the hand grip, a spray head fastened with a muzzle of the barrel, and a trigger fastened with the hand grip for activating the spraying mechanism of the pistol-type nozzle. The spray head and the muzzle are fastened together by an L-shaped mortise-tenon structure. The spray head and the muzzle are apt to separate from each other when the spray head is inadvertently pistol-type nozzle is integrally made of a rigid plastic material by injection molding and is therefore devoid of a soothing effect.

[0005] The primary objective of the present invention is to provide a pistol-type nozzle which is free of the deficiencies of the prior art nozzle described above.

[0006] In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by a pistol-type nozzle comprising a hand grip, a barrel, a spray head, and a trigger. The muzzle of the barrel is provided in the outer wall with an annular groove and two retaining slots. The spray head is provided in the inner wall with two retaining projections corresponding in location to the retaining slots of the muzzle. The spray head is fastened with the muzzle in conjunction with a washer which is located in the annular groove of the muzzle. The retaining projections of the spray head are securely located in the retaining slots of the muzzle such that the retaining projections are arrested by an arresting ridge extending from the bottom wall of the retaining slots. The trigger has a press portion which is provided with a cover having a soothing effect.

[0007] The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of the present invention with reference to the accompanying drawings.

[0014] As shown in FIGS. 1–5, a pistol-type nozzle 10 of the present invention comprises a hand grip 11, a barrel extending from the hand grip 11 and having a muzzle 12, and a spray head 20 fastened with the muzzle 12.

[0015] The muzzle 12 is provided in the outer wall with an annular groove 13, and two L-shaped retaining slots 15. The retaining slots 15 are opposite in location to each other and are formed of a guide portion 151 and a retaining portion 152, as shown in FIG. 3. The retaining portion 152 is provided in the bottom wall with a retaining ridge 153.

[0016] The spray head 20 is provided with a connection end 21 and is further provided in the inner wall in proximity of the connection end 21 with two retaining projections 22 corresponding in location to the retaining slots 15 of the muzzle 12. The connection end 21 of the spray head 20 is joined with the muzzle 12 in conjunction with a washer 14 which is located in the annular groove 13 of the muzzle 12. The spray head 20 and the muzzle 12 are held together by the retaining projections 22, which are securely located in the retaining portion 152 of the retaining slot 15 such that the retaining projections 22 are arrested by the retaining ridge 153 of the retaining portions 152, as illustrated in FIGS. 4 and 5. In the process of joining the connection end 21 of the spray head 20 with the muzzle 12, the retaining projections 22 of the spray head 20 are inserted into the retaining slots 15 of the muzzle 12 via the guide portion 151 of the retaining slots 15.

[0017] The pistol-type nozzle 10 of the present invention further comprises a trigger 30, which is fastened to the hand grip 11. The trigger 30 is pressed by the finger to activate the spraying mechanism of the pistol-type nozzle 10 of the present invention. The trigger 30 has a press portion which is provided with a recess 31 to accommodate a cover 40. The recess 31 is provided in the bottom wall with a plurality of retaining holes 32. The cover 40 is provided in the underside with a plurality of retaining protrusions 41 corresponding in location to the retaining holes 32. The cover 40 is securely held in the recess 31 of the trigger 30 such that the retaining protrusions 41 are retained in the retaining holes 32, as shown in FIG. 6. The cover 40 has a soothing effect. The cover 40 is made of a rubber material, or a foam material. The cover 40 is used to soothe the finger by which the trigger 30 is pressed to activate the spraying mechanism of the pistol-type nozzle 10 of the present invention.

[0018] The present invention described above is to be regarded in all respects as being illustrative and nonrestrictive. Accordingly, the present invention may be embodied in other specific forms without deviating from the spirit thereof. The present invention is therefore to be limited only by the scopes of the following claims.
