Atomizing rotary spray head

Abstract

The application discloses an atomizing rotary nozzle, belonging to the spray technology, and has the problems of difficult starting, slow rotation and poor spraying effect when the liquid pressure is low in the prior art. The application is configured with a cavity, and a driving impeller is arranged in the cavity at the second end of the tubular main shaft. When the pressure liquid flows through the liquid inlet channel of the tail seat, the cavity, the tubular main shaft and the nozzle assembly in sequence, the counter-thrust of the spray on the inclined nozzle promotes the rotation of the nozzle assembly, the fan wheel and the tubular main shaft. When the pressure liquid flows through the driving impeller, the driving impeller is subjected to the impact force, and the rotation of the driving impeller is promoted. The rotation of the impeller further drives the nozzle assembly and the fan wheel to rotate through the tubular main shaft, thereby providing power for the rotation of the nozzle assembly and the fan wheel. The nozzle assembly and the fan wheel are started smoothly and conveniently, and rotate fast after starting, and the spraying effect is good.

Description

Technical Field

[0001] This invention pertains to spray technology, specifically relating to an atomizing rotary nozzle. Background Technology

[0002] Existing atomizing rotary nozzles used for spraying pesticides and other applications are difficult to start when the liquid pressure is low, rotate slowly after starting, and have poor spraying effect. Summary of the Invention

[0003] This invention addresses the shortcomings of existing atomizing rotary nozzles, such as difficulty in starting when the liquid pressure is low, slow rotation after starting, and poor spraying effect. It provides an atomizing rotary nozzle that assists the nozzle assembly, impeller, and tubular main shaft to rotate under the action of pressurized liquid by driving an impeller. This allows for smooth start-up even when the liquid pressure is low, fast rotation after starting, and good spraying effect.

[0004] To achieve the above objectives, the atomizing rotary nozzle of the present invention is characterized by comprising: Tubular body; A tubular spindle extends in the same direction as the tubular body and is rotatably assembled inside the tubular body; A nozzle assembly connected to the first end of a tubular main shaft includes an angled nozzle mounted at an angle relative to a circumferential surface, the circumferential surface being a plane perpendicular to the tubular main shaft; The impeller is located at the first end of the tubular main shaft and rotates together with the nozzle assembly; The tailstock is assembled at the rear end of the tubular body and is provided with a liquid inlet channel. A cavity communicating with the liquid inlet channel is maintained between the tailstock and the tubular body. The drive impeller is located in the cavity and assembled at the second end of the tubular main shaft; As the pressurized liquid flows sequentially through the inlet channel, cavity, tubular main shaft, and nozzle assembly of the tailstock, the reverse thrust of the spray on the angled nozzle causes the nozzle assembly, impeller, and tubular main shaft to rotate, and drives the impeller to assist the rotation of the nozzle assembly, impeller, and tubular main shaft under the action of the pressurized liquid.

[0005] This atomizing rotary nozzle uses the reverse thrust of the spray on the angled nozzle to cause the nozzle assembly, impeller, and tubular main shaft to rotate. Furthermore, by mounting a drive impeller at the second end of the tubular main shaft, the pressurized liquid flowing through the drive impeller exerts an impact force on it, causing the drive impeller to rotate. The rotation of the impeller further drives the nozzle assembly and impeller to rotate through the tubular main shaft, providing assistance for the rotation of the nozzle assembly and impeller, making the nozzle assembly and impeller start smoothly and easily, and rotating quickly after starting, resulting in good spraying effect.

[0006] Preferably, the tubular spindle is rotatably mounted to the tubular body via a bearing assembly, and a drain hole is provided on the wall of the corresponding bearing assembly of the tubular body. This is used to drain liquid that enters the bearing assembly, preventing the bearing assembly from being immersed in liquid and reducing its lifespan. Furthermore, it facilitates heat dissipation from the bearing assembly.

[0007] Preferably, the bearing assembly includes a first radial bearing, a second radial bearing, and an axial bearing fitted onto the tubular spindle, with the axial bearing located between the first and second radial bearings. Accordingly, the first and second radial bearings provide rotational support for the tubular spindle, while the axial bearing provides axial support, ensuring that the tubular spindle rotates flexibly without wobbling or shifting.

[0008] Preferably, an anti-fog ring is fitted onto the outside of one end of the tubular body adjacent to the nozzle assembly, and a sealing assembly is fitted onto the inside of the tubular body. The anti-fog ring and the sealing assembly are located on opposite axial sides of the bearing assembly to prevent liquid or mist from entering the assembly cavity of the bearing assembly. This effectively prevents liquid or mist from entering the assembly cavity of the bearing assembly, ensuring a safe working environment for the bearing assembly.

[0009] Preferably, a first set screw is fitted to the side wall of the tubular body, and the sealing assembly is fixed by the first set screw. Accordingly, the sealing assembly is positioned within the tubular body and can serve as axial support for the bearing assembly.

[0010] Preferably, the tubular spindle includes a first shaft segment and a second shaft segment that are joined together. The first shaft segment is equipped with a bearing assembly, and the second shaft segment is equipped with a sealing assembly. The second shaft segment is made of ceramic material. This increases the wear resistance and lifespan of the second shaft segment and ensures that the sealing assembly can provide a durable seal.

[0011] Preferably, the tailstock includes a mounting nut, an interface nut, and a flow guide. The flow guide has a flow-guiding oblique hole and is placed inside the interface nut. The interface nut is pressed and locked by the mounting nut to the end of the tubular body away from the nozzle assembly. Accordingly, the pressure liquid is guided by the flow-guiding oblique hole to impact and drive the impeller at a suitable angle. The impeller applies torque to the tubular main shaft, causing the main shaft to rotate.

[0012] Preferably, the nozzle assembly includes a central connector connected to the first end of a tubular main shaft and a plurality of branch pipes extending radially outward from the central connector. Angled nozzles are fitted to the outer ends of the branch pipes, and straight nozzles are fitted to the central connector, with the straight nozzles perpendicular to the circumferential surface. Accordingly, the angled nozzles maintain a distance from the tubular main shaft, which determines the lever arm of the reaction force of the spray on the angled nozzles. This allows for the application of a larger torque to the nozzle assembly, facilitating smooth and easy start-up, rapid rotation after start-up, and good spraying effect.

[0013] Preferably, the impeller is located at the rear of the nozzle assembly. The impeller has a central hole and multiple forward-facing slots extending radially outward from the central hole. A central connecting pipe passes through the central hole, and branch pipes are located in the corresponding slots. The impeller is pressed into the nozzle assembly by a clamping nut located at its rear and connected to the central connecting pipe. This results in a compact assembly structure between the nozzle assembly and the impeller, a lightweight impeller structure, and reduced resistance during the start-up and rotation of the nozzle assembly and the impeller.

[0014] Preferably, the impeller includes a peripheral wall, a central section, spokes, and blades. The spokes and blades are connected between the peripheral wall and the central section. A central hole is located in the central section, and slots are located in the spokes. Through holes corresponding to the angled nozzles are formed on the spokes. This impeller structure forms an integral structure with high strength and rigidity, which is beneficial for lightweight design. The through holes corresponding to the angled nozzles can supplement airflow from the back side of the impeller to the angled nozzles, providing a suitable airflow environment for the liquid or mist sprayed by the angled nozzles, and promoting uniform spraying of the liquid or mist under the action of the impeller.

[0015] This invention utilizes a cavity configuration, with a drive impeller mounted at the second end of the tubular main shaft. As pressurized liquid flows sequentially through the inlet channel of the tailstock, the cavity, the tubular main shaft, and the nozzle assembly, the spray's counterforce against the angled nozzle causes the nozzle assembly, impeller, and tubular main shaft to rotate. The pressurized liquid also exerts an impact force on the drive impeller, causing it to rotate. This rotation further drives the nozzle assembly and impeller via the tubular main shaft, providing assistance for their rotation. This results in smooth and easy start-up of the nozzle assembly and impeller, rapid rotation after startup, and excellent spraying effect. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0018] The terms “comprising” and “having”, and any variations thereof, used in the specification and claims of this invention are intended to cover a non-exclusive inclusion, such as a method or product that includes a series of technical features, not necessarily limited to those technical features explicitly listed, but may also include other technical features that may be included in the method or product but not explicitly listed.

[0019] In the description of this invention, it should be understood that the technical features defined by terms such as "first" and "second" which have a sequential concept are only used to clearly describe the defined technical features and to clearly distinguish the defined technical features from other technical features, and do not represent that they are named in this way in actual implementation. Therefore, they should not be construed as limitations on this invention.

[0020] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0021] Figure 1-6 A preferred embodiment of an atomizing rotary nozzle is shown, which includes a tubular body 100, a tubular main shaft 200, a nozzle assembly 300, a fan 400, a tailstock 500, and a drive impeller 600.

[0022] The tubular body 100 is a circular tubular component with an end wall 101 at its front end, a shaft hole 102 on the end wall 101, and an open end 103 at its rear end. The open end 103 provides access to the interior of the tubular body for assembling components such as the tubular main shaft 200, bearing assembly 230, and sealing assembly 120. In this application, "front" is defined as the direction of liquid or mist spraying. The orientation of the straight nozzle 320 mentioned below is "front," and "rear" is the opposite direction to "front."

[0023] The tubular spindle 200 extends in the same direction as the tubular body 100 and is rotatably assembled inside the tubular body 100. The tubular spindle 200 is a hollow tube, and its interior serves as a flow channel for liquid. To ensure flow rate, a flow hole 201 is provided on the tube wall at the lower end of the tubular spindle 200.

[0024] The nozzle assembly 300 is connected to the first end of the tubular main shaft, specifically, via a central connecting pipe 330 threadedly connected to the first end of the tubular main shaft. The nozzle assembly 300 includes an angled nozzle 310 mounted at an angle relative to a circumferential surface, which is a plane perpendicular to the tubular main shaft 200.

[0025] The impeller 400 is located at the first end of the tubular main shaft 200 and rotates together with the nozzle assembly 300. It should be noted that the impeller being located at the first end of the tubular main shaft only indicates the positional relationship, that is, the impeller is located at the first end of the tubular main shaft relative to the tubular main shaft, not in the middle or at the second end.

[0026] The tailstock 500 is mounted on the rear end of the tubular body 100 and is provided with a liquid inlet channel 501. A cavity 104 communicating with the liquid inlet channel 501 is maintained between the tailstock 500 and the tubular body 100. The tailstock 500 is used to install the entire atomizing rotary nozzle into the required position. Therefore, the mounting nut 510, which is described below, is provided with mounting threads.

[0027] The drive impeller 600 is located in the cavity 104 and is mounted on the second end of the tubular main shaft 200. To ensure liquid flow, the central part of the drive impeller is hollow and corresponds to the port of the second end of the tubular main shaft. To transmit torque, the drive impeller 600 and the tubular main shaft 200 are axially connected via splines, and during connection, they are axially sleeved to maintain the assembly relationship. The function of this drive impeller 600 differs from that of a water pump impeller. While a water pump impeller applies pressure to water through its own rotation to drive water flow, this drive impeller rotates based on the impact of pressurized liquid.

[0028] When the pressurized liquid flows sequentially through the inlet channel 501, cavity 104, tubular main shaft 200 and nozzle assembly 300 of the tailstock, the spray's reverse thrust on the angled nozzle 310 causes the nozzle assembly 300, impeller 400 and tubular main shaft 200 to rotate, and drives the impeller 600 to assist the rotation of the nozzle assembly 300, impeller 400 and tubular main shaft 200 under the action of pressurized liquid.

[0029] This atomizing rotary nozzle uses the reverse thrust of the spray on the angled nozzle to cause the nozzle assembly, impeller, and tubular main shaft to rotate. Furthermore, by mounting a drive impeller at the second end of the tubular main shaft, the pressurized liquid flowing through the drive impeller exerts an impact force on it, causing the drive impeller to rotate. The rotation of the impeller further drives the nozzle assembly and impeller to rotate through the tubular main shaft, providing assistance for the rotation of the nozzle assembly and impeller, making the nozzle assembly and impeller start smoothly and easily, and rotating quickly after starting, resulting in good spraying effect.

[0030] The above structure embodies the basic concept of the present invention, enabling the realization of the technical solution of the present invention. To further improve the technical solution, based on the above structure, the following preferred technical means can be selected to obtain better embodiments.

[0031] like Figure 3-6As shown, the tubular spindle 200 is rotatably mounted to the tubular body 100 via the bearing assembly 230. A drain hole 105 is provided on the wall of the tubular body 100 corresponding to the bearing assembly 230. The drain hole is used to drain liquid entering the assembly cavity of the bearing assembly, preventing the bearing assembly from being immersed in liquid and reducing its lifespan. It also facilitates heat dissipation from the bearing assembly. In particular, the bearing pad 270 has a guide groove 271 corresponding to the drain hole 105 on its side facing the bearing assembly, which guides the liquid out of the assembly cavity of the bearing assembly. This effect is especially noticeable when the nozzle assembly is facing forward during operation.

[0032] like Figure 3-6 , Figure 8-9 As shown, the bearing assembly 230 includes a first radial bearing 231, a second radial bearing 232, and an axial bearing 233 fitted onto the tubular spindle 200, with the axial bearing located between the first and second radial bearings. The first and second radial bearings 231 and 232 are preferably radial ball bearings, and the axial bearing 233 is preferably a planar bearing. Accordingly, the first and second radial bearings provide rotational support for the tubular spindle, while the axial bearing provides axial support, ensuring flexible rotation of the tubular spindle without wobbling or shifting. To position the bearings, a first shaft retaining ring 240 and a second shaft retaining ring 250 are mounted on the tubular spindle 200. The axial bearing 233 is axially positioned between the two shaft retaining rings. The first radial bearing 231 is located between the washer 260 and the end wall 101, and the second radial bearing 232 is located between the second shaft retaining ring 250 and the bearing washer 270, which is axially positioned by the sealing assembly 120 described below.

[0033] like Figure 3-6 , Figure 8-9 As shown, an anti-fog ring 110 is fitted onto the outside of one end of the tubular body 100 adjacent to the nozzle assembly 300 and onto the tubular spindle 200. A sealing assembly 120 is fitted onto the inside of the tubular body 100 and onto the tubular spindle 200. The anti-fog ring 110 and the sealing assembly 120 are positioned on opposite axial sides of the bearing assembly 230 to prevent liquid or mist from entering the assembly cavity of the bearing assembly 230. This effectively prevents liquid or mist from entering the assembly cavity of the bearing assembly, ensuring a safe working environment for the bearing assembly. The anti-fog ring 110 is pressed against the end wall 101 by a clamping nut 111, which is threaded onto the tubular spindle 200 and fixed to the tubular spindle by a second set screw 112.

[0034] like Figure 2 , Figure 4As shown, a first set screw 130 is fitted to the side wall of the tubular body 100, and the sealing assembly 120 is fixed by the first set screw 130. Specifically, the first set screw 130 presses against the bracket 121 to fix the sealing assembly 120. Accordingly, the sealing assembly is positioned inside the tubular body and can serve as axial support for the bearing assembly.

[0035] like Figure 8-9 As shown, the tubular spindle 200 includes a first shaft segment 210 and a second shaft segment 220 that are joined together. The first shaft segment 210 is equipped with a bearing assembly 230, and the second shaft segment 220 is equipped with a sealing assembly 120. The second shaft segment 220 is made of ceramic. This increases the wear resistance and lifespan of the second shaft segment and ensures that the sealing assembly can provide a durable seal. To achieve synchronous rotation of the first shaft segment 210 and the second shaft segment 220, the first shaft segment 210 and the second shaft segment 220 are also joined by a spline and fixed with a strong sealant.

[0036] like Figure 3-4 As shown, the sealing assembly 120 includes a bracket 121 and a first O-ring 122, a second O-ring 123, a third O-ring 124, a first Y-ring 125, and a second Y-ring 126 attached to the bracket, thereby isolating the cavity 104 from the bearing assembly 230.

[0037] like Figure 7 As shown, the tailstock 500 includes a mounting nut 510, an interface nut 520, and a flow guide 530. The flow guide 530 has a flow guide oblique hole 531. The flow guide 530 is placed inside the interface nut 520, which is pressed and locked by the mounting nut 510 to the end of the tubular body 100 away from the nozzle assembly (i.e., the rear end). Accordingly, guided by the flow guide oblique hole, pressurized liquid impacts the impeller at a suitable angle, and the impeller applies torque to the tubular main shaft, causing the main shaft to rotate.

[0038] Since this atomizing rotary nozzle is used to atomize liquid, seals are installed between mating components in the liquid delivery channel to prevent leakage and ensure a tight seal. For example... Figure 3-4 As shown, in addition to the sealing assembly 120 assembled between the tubular spindle 200 and the inner wall of the tubular body, these seals also include a fourth O-ring 540 between the mounting nut 510 and the interface nut 520, a fifth O-ring 550 between the guide 530 and the interface nut 520, and a sixth O-ring 560 between the interface nut 520 and the open edge of the tubular body 100.

[0039] like Figure 10-11As shown, the nozzle assembly 300 includes a central connector 330 connected to the first end of the tubular main shaft 200 and a plurality of branch pipes 340 extending radially outward from the central connector. Angled nozzles 310 are mounted at the outer ends of the branch pipes 340, and straight nozzles 320 are mounted on the central connector 330, with the straight nozzles 320 perpendicular to the circumferential surface. Accordingly, the angled nozzles maintain a distance from the tubular main shaft, which determines the lever arm of the reaction force of the spray on the angled nozzles, thereby enabling the application of a larger torque to the nozzle assembly, facilitating smooth and easy start-up of the nozzle assembly, rapid rotation after start-up, and good spraying effect. Both the angled and straight nozzles are used to atomize liquid; they have the same structure but are named differently due to their different assembly orientations. Furthermore, both the angled and straight nozzles are installed via threads.

[0040] like Figure 10-11 As shown, the impeller 400 is located at the rear of the nozzle assembly 300. The impeller 400 has a central hole 406 and multiple forward-facing slots 407 extending radially outward from the central hole. A central connecting pipe 330 passes through the central hole 406, and branch pipes 340 are located in the corresponding slots 407. The impeller 400 is pressed against the nozzle assembly by a clamping nut 410 located at its rear and connected to the central connecting pipe 330. This design results in a compact assembly structure between the nozzle assembly and the impeller, a lightweight impeller structure, and reduced resistance during start-up and rotation of the nozzle assembly and the impeller.

[0041] like Figure 10-11 As shown, the impeller 400 includes a peripheral wall 401, a central portion 402, spokes 403, and blades 404. The spokes 403 and blades 404 are connected between the peripheral wall 401 and the central portion 402. A central hole 406 is located in the central portion 402, and a groove 407 is located in the spokes 403. Through holes 405 corresponding to the angled nozzles 310 are provided on the spokes 403. This impeller structure forms an integral structure with high strength and rigidity, which is conducive to lightweight design. The through holes 405 corresponding to the angled nozzles can supplement airflow from the back side of the impeller to the angled nozzles, providing a suitable airflow environment for the liquid or mist sprayed by the angled nozzles, and promoting uniform spraying of the liquid or mist under the action of the impeller.
