AI Technical Summary
Traditional sprinkler heads have complex structures, large water flow energy loss, short range, and cannot be adjusted in height or the adjustment cost is high, resulting in a fixed spray range that cannot adapt to the needs of plants at different growth stages.
A nozzle structure was designed, comprising a water outlet and a baffle. The water outlet has a flow channel inside and a constriction near the water outlet to increase water pressure. The baffle has a convex surface, and the water flow forms a divergent water flow. The height can be adjusted by cooperating with the upright to change the spray range.
It achieves low water flow energy loss, adjustable range, adapts to the spraying needs of plants at different growth stages, improves water utilization and spraying efficiency, and reduces costs.

[0016] The utility model will be further described below in conjunction with the drawings and examples.
[0017] In the description of the utility model, it needs to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.
[0018] As shown in Figures 1 to 4 The embodiment discloses a micro spray head, which is used in cooperation with a stand 1 and a water pipe 3.
[0019] The spray head 2 comprises a water outlet part 25 and a baffle 21, the water outlet part 25 is internally provided with a flow channel 24, the flow channel 24 is provided with a water inlet hole and a water outlet hole 22, the flow channel 24 is provided with a necking 23 at a position close to the water outlet hole 22 to increase the water outlet pressure, the baffle 21 is opposite to the water outlet hole 22, and one side of the baffle 21 opposite to the water outlet hole 22 is a convex surface; the water column sprayed from the water outlet hole 22 is sprayed on the convex surface of the baffle 21 to form a divergent water flow.
[0020] Preferably, the flow channel 24 in the water outlet part 25 is linear, so that the water flow loss is small.
[0021] Preferably, the spray head 2 further comprises a connecting part 26, the connecting part 26 is provided with a through hole, and the axial direction of the through hole is parallel to the flow channel 24; the spray head 2 is sleeved on the stand 1 through the through hole and is adjustable in height.
[0022] In use, the stand is fixed on the ground (and can be directly inserted into the soil), the water pipe 3 (for example, a PVC pipe) is tightly inserted into the water inlet hole of the spray head 2 (or is sleeved on the water inlet hole position of the spray head 2), and the flow channel in the spray head 2 is provided with a necking 23 at a position close to the water outlet hole 22, so that the water outlet pressure can be increased, and the water column is sprayed on the bottom surface of the baffle 21. The bottom surface of the baffle 21 of the embodiment is in the shape of a convex spherical surface, and the water column sprayed on the convex spherical surface is in the form of a divergent water flow. The bottom surface of the baffle 21 can also be provided in other shapes, for example, a concave spherical surface, a conical shape and the like.
[0023] Water flows from the water pipe 3, reaches the nozzle 2, and accelerates from the water outlet hole 22 of the nozzle 2 to directly impact the baffle 21, and the water flow is dispersed along the convex spherical surface of the baffle 21, and the water spray is divergent. The nozzle 2 has a simple structure, and by setting the necking 23 near the water outlet hole 22, only the accelerated water flow is used to impact the baffle 21 to achieve divergent water spray, improve the spraying range, and improve the water utilization rate.
[0024] The nozzle 2 can move up and down along the vertical rod 1, and when the nozzle 2 is at a higher position, the spraying range is increased, and when the nozzle 2 is at a lower position, the spraying range is reduced. By changing the height, the spraying range is changed, and the spraying requirements of plants or other objects in different periods are met; by changing the spraying range, the applicability of the product is improved, which is beneficial to the growth of plants in the whole cycle, has low cost, and is high in efficiency.
