Description

Technical Field

[0001] This utility model relates to the field of sprayers, specifically to a water sprinkler. Background Technology

[0002] Modern sprinklers vary greatly in size, cost, and complexity. They include impact sprinklers, oscillating sprinklers, drip sprinklers, subsurface sprinkler systems, and portable sprinklers, each designed to meet different needs. Household sprinklers expand the spraying area by using angle adjustment devices, but most angle adjustment devices are complex in structure and their reliability is low due to structural and material limitations over long-term use. Therefore, there is a market demand for a sprinkler with a simple structure and high reliability.

[0003] A search revealed that patent number CN202322967388 discloses a sprayer with adjustable nozzle angle, comprising a rocker base with a water inlet chamber. Multiple flexible nozzles communicating with the water inlet chamber are arranged on the upper side of the rocker base. An adjustment mechanism for adjusting the spray angle of the flexible nozzles is also provided on the upper side of the rocker base. The adjustment mechanism includes a sliding plate and an adjusting rod. The sliding plate is laterally slidable on the upper side of the rocker base and has adjustment holes. The flexible nozzles pass through the corresponding adjustment holes. The adjusting rod rotates with the rocker base and is equipped with an adjusting wheel. The sliding plate has an adjusting rack that meshes with the adjusting wheel. The spray direction of the flexible nozzles can be adjusted through the adjustment mechanism. Furthermore, this design achieves adjustment only through the cooperation of the adjusting rod, adjusting wheel, and sliding plate, resulting in a simple structure, small space occupation, and thus a reduced overall size of the sprayer. Operation is convenient; the sliding plate can be adjusted laterally by rotating the adjusting rod via the adjusting wheel. Its shortcomings are: the rack and toothed limiting structure is set between the top cover and the upper cover, and these structures are distributed near the flexible nozzle, or even above the nozzle orifice, which can easily affect the water pattern and requires further improvement. Summary of the Invention

[0004] This utility model addresses the problems of existing technology by proposing a sprinkler that optimizes accessories and reduces the impact on water patterns.

[0005] The technical solution of this utility model is: a sprinkler, comprising:

[0006] A rocking seat has a water inlet chamber, and the top of the water inlet chamber is provided with multiple flexible nozzles that communicate with the water inlet chamber; a top cover is fixed to the top of the water inlet chamber, and the top cover is provided with multiple water outlet holes to allow the flexible nozzles to extend.

[0007] An adjustment mechanism, including a sliding plate and an adjustment rod, is disposed on the top of the upper cover for adjusting the spray angle of the flexible nozzle;

[0008] A sliding plate, located on the top cover, can move horizontally left and right.

[0009] The adjusting rod, located below the sliding plate, drives the sliding plate to slide.

[0010] A top cover is fixed to the top of the sprinkler, and the top cover has multiple water outlet holes to expose the flexible nozzles;

[0011] Its characteristic is that the upper cover includes:

[0012] The limiting tooth groove is arranged on the inner side of the upper cover, and the corresponding sliding plate has a limiting toothed strip on its side wall to match it, so as to achieve limiting and fixing.

[0013] Furthermore, the limiting tooth grooves are arranged on the inner side walls of both sides of the upper cover.

[0014] Furthermore, the bottom of the sliding plate is provided with an adjusting rack, and correspondingly, the adjusting rod has an adjusting gear that cooperates with it to realize transmission.

[0015] Furthermore, the sliding plate consists of two pieces arranged on the left and right sides. The opposite parts of the left and right sliding plates adopt a stepped mating structure to improve sliding stability. The outer wall of the sliding plate is provided with a groove to prevent the sliding plate from affecting the operation of the adjustment mechanism when it moves horizontally.

[0016] Furthermore, the adjusting gear is a half gear. When the part of the adjusting gear without teeth is not moving, it will not drive the sliding plate to move, thus achieving the limiting function.

[0017] Furthermore, the upper cover has a groove in the middle that matches the adjusting gear to prevent the adjusting gear from being affected when rotating.

[0018] Finally: The end of the adjusting rod is fixed with a lever, and both sides of the lever are provided with limiting parts. Correspondingly, the upper cover is also provided with lever holes corresponding to the lever.

[0019] Compared with existing technologies, the advantages of this product are: the limiting rack of the sliding plate and the limiting groove of the upper cover cooperate with each other, so that while maintaining the limiting movement function, the rack and the tooth-fitting limiting structure are kept away from the mouth of the flexible nozzle, ensuring that it is below the mouth of the nozzle, thereby reducing the impact of the parts on the water pattern.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] according to Figures 1 to 8 A sprinkler includes: a rocker seat 1 having a water inlet chamber 2, and a plurality of flexible nozzles 3 communicating with the water inlet chamber 2 at the top; a top cover 4 fixed to the top of the water inlet chamber 2, the top cover 4 having a plurality of water outlet holes 5 for the flexible nozzles 3 to extend out; an adjustment mechanism 6 including a sliding plate 7 and an adjustment rod 8, disposed on the top of the top cover 4 for adjusting the spray angle of the flexible nozzles 3; the sliding plate 7 is arranged on the top cover 4 and can be moved to the left or right; the adjustment rod 8 is below the sliding plate 7 and drives the sliding plate 7 to slide; a top cover 17 fixed to the top of the sprinkler, the top cover 17 having a plurality of water outlet holes 5 for the flexible nozzles 3 to be exposed; the key improvement is that the top cover 4 includes: a limiting tooth groove 9 arranged on the inner side wall of the top cover 4, and a corresponding limiting toothed strip 10 on the side wall of the sliding plate 7 to match it, thereby achieving limiting and fixing.

[0034] The limiting tooth grooves 9 are preferably arranged on the inner side walls of both sides of the upper cover 4. Correspondingly, the two sides of the sliding plate 7 are also provided with corresponding limiting toothed racks 10. The two sides are fixed by limiting, thereby increasing the firmness. The limiting tooth grooves 9 have multiple stroke positions, and the limiting toothed racks 10 can be limited and locked at different stroke positions. The sliding plate 7 consists of two pieces arranged left and right. The bottom of the sliding plate 7 is provided with an adjusting rack 20. Correspondingly, the adjusting rod 8 has an adjusting gear 15 that cooperates with it to realize transmission. The opposite parts of the left and right sliding plates 7 adopt a stepped mating structure A to improve sliding stability. Each row of the sliding plate 7 is provided with an adjusting hole 12, which provides sliding stability and improves the spraying effect. The outer side wall of the sliding plate 7 is provided with a slot 11. Both ends of the adjusting rod 8 pass through the slot 11 and come out, preventing the sliding plate 7 from affecting the operation of the adjusting mechanism 6 when it moves horizontally. Since the bottom of the flexible nozzle 3 is fixed, the water flow is easily uneven when adjusting the angle of flexible nozzles 3 of different thicknesses. Therefore, the sliding plate 7 is provided with adjustment holes 12 of different diameters. When the adjustment angles of the adjustment holes 12 in different rows are different, the uniformity of the adjustment angle and direction of different flexible nozzles 3 is ensured. The top of the sliding plate 7 is provided with a slider 19, which cooperates with the top cover to reduce the frictional resistance when the sliding plate 7 slides. The end of the adjusting rod 8 is fixed with a paddle 13. Both sides of the paddle 13 are provided with limiting parts 14. Correspondingly, the top cover 17 is also provided with a paddle hole 18 corresponding to the paddle 13, which cooperates with the limiting parts 14 to prevent the paddle 13 from rotating excessively.

[0035] The bottom of the sliding plate 7 is equipped with an adjusting rack 10. Correspondingly, the adjusting rod 8 has an adjusting gear 15 that engages with it. When the paddle 13 is turned, the adjusting rod 8 rotates, thereby driving the adjusting gear 15 to achieve transmission. The adjusting gear 15 is a half gear; when the part of the adjusting gear 15 without teeth is not moving, it will not drive the sliding plate 7 to move, thus achieving a limiting function. The upper cover 4 has a groove 16 in the middle, which matches the adjusting gear 15 to prevent the rotation of the adjusting gear 15 from being affected.

[0036] Because the limiting rack of the sliding plate and the limiting groove of the upper cover cooperate with each other, the limiting movement function remains unchanged, while the rack and the tooth-fitting limiting structure are kept away from the mouth of the flexible nozzle, ensuring that it is below the mouth of the nozzle. This reduces the impact of the parts on the water pattern, resulting in a more balanced water spray effect and smoother and more reliable sliding.
