Description

Technical Field

[0001] This utility model relates to the field of atomization equipment technology, specifically to an environmentally friendly high-pressure fine atomizing nozzle. Background Technology

[0002] Atomizing nozzles, as devices that convert liquids into mist particles, are widely used in various fields such as agricultural irrigation, industrial humidification, environmental dust removal, medical atomization, and garden maintenance. Based on their working principles and structural characteristics, they can be categorized into common types such as high-pressure atomizing nozzles, pneumatic atomizing nozzles, and ultrasonic atomizing nozzles.

[0003] Existing atomizing nozzles suffer from the following technical defects: 1. The nozzle holder and body of existing atomizing nozzles are mostly fixedly connected, making disassembly and maintenance difficult. When internal components are worn or clogged, the entire nozzle needs to be replaced, increasing usage costs and wasting resources; 2. The nozzle outlet structure design on the market is unreasonable, resulting in coarse and uneven atomized particles, which cannot meet the needs of high-precision atomization scenarios, such as humidification in electronic factories and cooling of precision instruments, thus affecting the application range; 3. The existing flow divider cores have a single distribution pattern for the flow divider holes, mostly arranged in a straight line or a simple ring, resulting in poor liquid flow division, insufficient subsequent atomization, low liquid utilization, and waste; 4. Most nozzles lack effective filtration devices at the inlet, or the filtration accuracy is insufficient, allowing impurities in the liquid to easily enter the nozzle, causing blockage, affecting the atomization effect and normal operation of the equipment, and increasing maintenance frequency; 5. Some nozzles lack a flow guiding structure inside the pressurization chamber, making it easy for turbulence and eddies to be generated during liquid flow, reducing the pressurization effect, resulting in insufficient liquid kinetic energy, affecting the fineness of atomized particles and the atomization range.

[0004] Therefore, it is necessary to design an environmentally friendly high-pressure fine atomizing nozzle to solve the problems mentioned above. Utility Model Content

[0005] This utility model provides an environmentally friendly high-pressure fine atomizing nozzle head, which achieves functions such as detachable maintenance, high-efficiency atomization, precise flow adjustment, and corrosion resistance and environmental protection through optimized structural design and material selection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An environmentally friendly high-pressure fine atomizing nozzle includes a nozzle body. The front end of the nozzle body is connected to an integrated nozzle holder via a nozzle holder connecting nut. The integrated nozzle holder houses the nozzle, and its interior contains a multi-hole flow divider. The integrated nozzle holder is made of stainless steel with a 0.05-0.1mm thick anti-corrosion coating. This design effectively resists corrosion, extends service life, reduces resource waste due to component replacement, aligns with environmental protection principles, and ensures stable operation in various complex environments. The nozzle's outlet end has a tapered structure with a contraction angle between 15° and 30°. This design significantly enhances atomization, allowing for more complete liquid atomization. The multi-hole flow divider has staggered, quincunx-like distribution of flow divider holes with a diameter of 0.1-0.2mm and a depth-to-diameter ratio of 3:1-5:1. This distribution and size ensure more uniform liquid distribution before entering the nozzle, laying the foundation for subsequent fine atomization.

[0007] Furthermore, the top of the nozzle body is equipped with an inlet and a handle. The inlet features a 200-300 mesh filter screen, which effectively filters impurities in the liquid, preventing them from clogging the nozzle and other components, ensuring the normal operation of the nozzle, and reducing maintenance costs. The handle is welded to the nozzle body and has a non-slip rubber sleeve with raised stripes on its surface, making it convenient for operators to carry and install the nozzle, improving operational ease.

[0008] Furthermore, a regulating valve is installed on one side of the nozzle body. This regulating valve consists of an adjusting knob and a valve core. The adjusting knob and the valve core are connected by a rotating shaft. Rotating the adjusting knob can move the valve core within the flow channel of the nozzle body, thereby flexibly adjusting the liquid flow rate to meet the flow requirements of different scenarios. A nozzle body connecting nut is provided on the rear side of the nozzle body for easy connection and installation of the nozzle with other equipment.

[0009] Furthermore, the nozzle body has a three-stage pressurization chamber, with the diameters of the three chambers decreasing sequentially and connected by a conical transition section, ultimately communicating with the nozzle. Simultaneously, the inner wall of each of the three pressurization chambers has 6-8 guide grooves arranged axially along the chamber wall. After entering from the inlet, the liquid is filtered to remove impurities by a filter screen, and then enters the three-stage pressurization chamber. Guided by the guide grooves, the liquid flows orderly along the chamber wall, gradually increasing in pressure through the three-stage pressurization chamber with decreasing diameters. This enhances the liquid pressure, and after being evenly distributed by a porous flow divider, it is ejected from the nozzle with a specific contraction angle, achieving fine atomization under high pressure.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This utility model, through the design of an environmentally friendly high-pressure fine atomizing nozzle, achieves the following effects: 1. By setting a nozzle seat connecting nut, the integrated nozzle seat and the nozzle body are detachably connected. When internal components malfunction, they can be disassembled and replaced individually without replacing the entire nozzle, reducing operating costs, minimizing resource waste, and improving the economic and environmental performance of the equipment; 2. The integrated nozzle seat is made of stainless steel with an anti-corrosion coating, significantly improving its corrosion resistance, extending its service life, reducing replacement frequency, conforming to the trend of green environmental protection, and ensuring the stability of atomization effect during long-term use; 3. The nozzle outlet is designed with a tapered structure, and the contraction angle is controlled between 15° and 30°, which effectively enhances the atomization effect of the liquid, making the atomized particles finer and more uniform, meeting the needs of high-precision atomization scenarios such as humidification in electronic factories and cooling of precision instruments, thus expanding the application range; 4. The multi-hole diversion core uses a staggered, plum-blossom pattern for the diversion holes. The nozzle features several key features: 1. Optimized liquid distribution, ensuring even distribution of the liquid into multiple fine streams, laying the foundation for thorough atomization, improving liquid utilization, reducing waste, and meeting environmental protection requirements; 2. A 200-300 mesh filter screen at the inlet effectively intercepts impurities in the liquid, preventing nozzle blockage, ensuring stable atomization, reducing maintenance frequency, extending equipment lifespan, and improving work efficiency; 3. A handle on the top of the nozzle body, welded firmly to the body, with anti-slip rubber sleeves and raised stripes increasing friction for easy handling and installation, especially in large equipment or high-altitude operations, enhancing operational convenience and safety; 4. Six to eight axial flow guide grooves on the inner wall of the three-stage pressurization chamber guide the orderly flow of liquid, reducing turbulence and eddies, enhancing pressurization, and providing sufficient kinetic energy to the liquid, thereby improving the fineness and atomization range of the atomized particles and enhancing overall atomization performance.

[0014] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are provided. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0015] Example 1 Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment provides an environmentally friendly high-pressure fine atomizing nozzle, including a nozzle body 1. The front end of the nozzle body 1 is connected to an integrated nozzle seat 2 via a nozzle seat connecting nut 23. The integrated nozzle seat 2 is made of stainless steel and has an anti-corrosion coating with a coating thickness of 0.05-0.1mm. A nozzle 21 is provided on the integrated nozzle seat 2. The outlet end of the nozzle 21 has a tapered structure with a contraction angle of 15°. The interior of the integrated nozzle seat 2 is provided with a porous flow divider core 22. The flow divider holes on the porous flow divider core 22 are distributed in a staggered plum blossom pattern. The diameter of the flow divider holes is 0.1-0.2mm, and the ratio of hole depth to hole diameter is 3:1-5:1.

[0016] Example 2 Please see Figure 1 Based on embodiment 1, this embodiment further specifies that the top of the nozzle body 1 is provided with an inlet 3 and a handle 4. A filter screen is provided at the inlet 3, and the mesh size of the filter screen is 200-300 mesh. The handle 4 is fixed to the nozzle body 1 by welding. The surface of the handle 4 is provided with an anti-slip rubber sleeve, and the surface of the rubber sleeve is provided with raised stripes.

[0017] Example 3 Please see Figure 2 and Figure 3 Based on embodiment 1, this embodiment further specifies that a regulating valve 5 is provided on one side of the nozzle body 1. The regulating valve 5 includes an adjusting knob and a valve core. The adjusting knob and the valve core are connected by a rotating shaft. Rotating the adjusting knob can drive the valve core to move in the flow channel inside the nozzle body 1, thereby regulating the liquid flow rate.

[0018] Example 4 Please see Figure 1 and Figure 2 Based on embodiment 1, this embodiment further specifies that a nozzle body connecting nut 6 is provided on the rear side of the nozzle body 1, and a three-stage pressurization chamber 7 is provided inside the nozzle body 1. The diameter of the three-stage pressurization chamber 7 decreases sequentially and is connected by a conical transition section, and finally communicates with the nozzle 21. 6-8 guide grooves are provided on the inner wall of the three-stage pressurization chamber 7, and the guide grooves are arranged axially along the cavity wall.

[0019] The working process of this utility model is as follows: When using this environmentally friendly high-pressure fine atomizing nozzle, the liquid first enters from the inlet 3 and passes through the filter screen at the inlet 3 to filter out impurities in the liquid, so as to avoid impurities clogging subsequent components and affecting the normal operation of the nozzle. The filtered liquid enters the three-stage pressurization chamber 7 inside the nozzle body 1. Under the guidance of 6-8 axial guide grooves on the inner wall of the three-stage pressurization chamber 7, the liquid flows orderly along the chamber wall. Because the diameters of the three-stage pressurization chambers 7 decrease sequentially and are connected by a conical transition section, the liquid is gradually pressurized during flow, resulting in a significant increase in pressure. The pressurized liquid then enters the porous distribution core 22 inside the integrated nozzle seat 2. The distribution holes (0.1-0.2 mm in diameter, with a depth-to-diameter ratio of 3:1-5:1) distributed in a staggered, plum-blossom pattern on the porous distribution core 22 evenly distribute the liquid, allowing it to enter the nozzle 21 more smoothly. The distributed liquid is then ejected from the nozzle 21. The tapered structure at the outlet end of the nozzle 21 (contraction angle 15°-30°) further enhances the atomization effect, resulting in a fine atomized liquid. Throughout the operation, the liquid flow rate can be adjusted via the regulating valve 5 on the side of the nozzle body 1. Rotating the regulating knob of the regulating valve 5 moves the valve core within the flow channel of the nozzle body 1, thereby achieving flexible flow control. The nozzle body connecting nut 6 is used to connect and fix the nozzle body 1 to external equipment, while the handle 4 facilitates the operator's carrying and installation of the nozzle.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
