Description

Technical Field

[0001] This utility model relates to the field of sprinkler irrigation technology, and in particular, to a nozzle structure. Background Technology

[0002] Currently, Chinese patent CN218872541U discloses a detachable conical nozzle, including a nozzle pipe with a base at its bottom and a housing; the nozzle pipe is movably installed in a mounting cavity, and a gap cavity is formed between the inner wall of the front end of the mounting cavity and the side wall of the front end of the nozzle pipe; an atomizing element; wherein, a vertical water inlet channel and a horizontal diversion channel are opened in the nozzle pipe, and the diversion channel connects the water inlet channel and the gap cavity; the water inlet of the water inlet channel passes through the base; an atomizing structure is provided between the front end of the nozzle pipe and the atomizing element for connecting the gap cavity and the atomizing port.

[0003] The detachable cone nozzle sprays a mist, which is easily blown away by crosswinds, making it difficult to spray accurately and impractical. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a nozzle structure that makes the sprayed water droplets, which are not easily blown away by crosswinds, thereby achieving the effect of precise irrigation and improving practicality.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a nozzle structure, including a shell, a nozzle pipe, and an atomizing element. The shell has an installation cavity, the nozzle pipe is located in the installation cavity, and a water injection hole is opened on the nozzle pipe. The atomizing element is located between the front end face of the installation cavity and the front end face of the nozzle pipe. A water outlet hole communicating with the front end face of the installation cavity is opened at the front end of the shell. A water guide hole communicating with the water injection hole is opened on the nozzle pipe. The water guide hole communicates with the atomizing channel on the atomizing element. A first air inlet hole communicating with the installation cavity is opened on the side wall of the shell. A second air inlet hole communicating with the water injection hole is opened on the nozzle pipe. The first air inlet hole and the second air inlet hole are connected.

[0006] To achieve the above technical solution, water enters the spray pipe through the water injection hole. During this process, external air passes through the first air inlet and the second air inlet and mixes with the water. Subsequently, the water is discharged from the water guide hole, passes through the atomizing component, and is finally discharged from the water outlet. Because the air and water are mixed beforehand, the water discharged from the water outlet is in the form of water droplets, which are not easily blown away by crosswinds, so as to achieve the effect of precise irrigation and improve practicality.

[0007] As a preferred embodiment of this utility model, the outer wall of the nozzle is provided with an air guide ring groove that communicates with the first air inlet, and the inner wall of the air guide ring groove is provided with a second air inlet.

[0008] By implementing the above technical solution, the housing is fitted onto the nozzle, allowing the first air inlet to connect with the second air inlet through the air guide ring groove, eliminating the need to align the first and second air inlets and improving installation convenience.

[0009] As a preferred embodiment of this utility model, a mixing groove communicating with a water injection hole is provided on the side wall of the air guide ring groove, and the mixing groove is communicating with a second air inlet hole.

[0010] The above technical solution, achieved by introducing a mixing channel, has the following effects: 1. Airflow optimization: It can generate rotation and turbulence in the airflow, which mixes thoroughly with water within the nozzle, thereby improving atomization efficiency and effect; 2. Uniform mixing: The airflow is more evenly distributed throughout the nozzle, avoiding situations where the airflow is too concentrated or sparse in a certain location, thus allowing water to contact the air evenly over a larger area; 3. Reduced backflow: It can reduce water backflow and prevent water from accumulating around the second air inlet, thereby improving the overall efficiency of the system.

[0011] As a preferred embodiment of this utility model, a guide groove is provided on the outer wall of the shell, and the first air inlet is located in the guide groove.

[0012] By implementing the above technical solution, airflow can enter the first air inlet more smoothly, thereby reducing turbulence when the airflow enters; in addition, it can reduce the resistance when the airflow enters the first air inlet, improve the efficiency of the entire system, and reduce energy loss; it can also control the speed and direction of the airflow more precisely.

[0013] As a preferred embodiment of this utility model, a positioning ring is connected to the outer wall of the nozzle, and the outer wall of the positioning ring abuts against the inner wall of the mounting cavity.

[0014] The above technical solution makes the connection between the nozzle and the housing more stable.

[0015] As a preferred embodiment of this utility model, the nozzle is provided with a diffuser hole, which is connected to the water injection hole. The inner diameter of the diffuser hole is larger than the inner diameter of the water injection hole. The diffuser hole is connected to the mixing groove, the second air inlet hole, and the water guide hole.

[0016] To achieve the above technical solution, water enters the diffuser hole from the water injection hole, and air enters the diffuser hole at the same time, so that the mixing between water and air can be more uniform.

[0017] As a preferred embodiment of this utility model, the front end face of the nozzle is provided with a mounting hole, the atomizing component includes an atomizing plate and a connecting seat, a plurality of atomizing plates are fixed to one side of the connecting seat, an atomizing channel is formed between adjacent atomizing plates, and a protrusion is connected to the connecting seat, the protrusion being embedded in the mounting hole.

[0018] The above technical solution makes the connection between the atomizing component and the spray pipe simpler.

[0019] As a preferred embodiment of this utility model, a limiting protrusion is fixedly connected to the inner wall of the mounting cavity, the limiting protrusion abuts against the outer wall of the atomizing plate, a guiding slope is provided on the limiting protrusion, and the water guide hole is connected to the mounting hole.

[0020] To achieve the above technical solution, water enters the diffuser hole from the water injection hole, and a portion of it enters the mounting hole from the diffuser hole, so that the water flow can exert force on the atomizing element, making the connection between the atomizing plate and the limiting protrusion tighter.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. Air enters the diffuser through the first and second air inlets, allowing water and air to mix thoroughly. After passing through the atomizing element, the water is sprayed outward in the form of droplets, which is not easily affected by crosswinds and achieves precise irrigation.

[0023] 2. The mixing tank allows for more thorough contact between the airflow and water;

[0024] 3. The design of the limiting protrusion and mounting hole makes the connection between the housing, atomizing component and nozzle tighter. Attached Figure Description
