Technical Field

[0001] This application relates to the field of nozzle technology, and in particular to a high-uniformity electrostatic misting nozzle structure. Background Technology

[0002] In many fields such as agricultural plant protection, industrial spraying, and environmental disinfection, it is often necessary to use nozzles to atomize liquids and spray them evenly.

[0003] Traditional atomizing nozzles have some shortcomings in use. For example, after the pesticide solution is atomized and sprayed, the adsorption effect of the droplets on the surface of the plant or the object being sprayed is generally poor, resulting in a significant reduction in the utilization rate of pesticides or coatings. Moreover, the uniformity of droplet distribution from ordinary nozzles is not ideal, and it is easy to have localized areas of excessively dense or sparse droplets, which affects the operation effect. Therefore, a high-uniformity electrostatic misting nozzle structure is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-uniformity electrostatic mist spray nozzle structure to solve the problems mentioned in the background art.

[0005] The high-uniformity electrostatic misting nozzle structure provided in this application adopts the following technical solution:

[0006] A high-uniformity electrostatic misting nozzle structure includes a nozzle body, which is cylindrical with a liquid inlet at one end and a mist outlet at the other end. The nozzle body has an installation cavity inside for installing atomizing components.

[0007] The atomizing assembly includes a pressure atomizing nozzle and a rotating atomizing disc. The pressure atomizing nozzle is installed at the liquid inlet of the nozzle body. The rotating atomizing disc is rotatably connected to the inner wall of the nozzle body through a mounting ring and is opposite to the liquid outlet direction of the pressure atomizing nozzle. The rotating atomizing disc is driven to rotate by a drive mechanism outside the nozzle body. The surface of the rotating atomizing disc is provided with multiple inclined atomizing teeth.

[0008] The outer wall of the nozzle body is threaded, and a mounting base and a nozzle cover are connected to the outer wall of the nozzle body by the thread. The mounting base abuts against the nozzle cover. The atomizing port of the nozzle body passes through the mounting base and is located inside the nozzle cover. An electrostatic generating component is installed on the inner wall of the nozzle cover.

[0009] Preferably, the electrostatic generating component includes an inner electrode ring and an electrode ring. The inner electrode ring is fixedly connected to the bottom outer wall of the nozzle cover, and its inner hole expands downward in a funnel shape at the bottom. The electrode ring is installed between the inner electrode ring and the nozzle cover.

[0010] Preferably, the bottom inner wall of the nozzle cover is provided with a slot, the inner wall of the slot is fitted with a retaining ring, and the electrode ring is fixedly connected to the outer wall of the retaining ring.

A secondary gear is fixedly connected to one end of the two rotating shafts located inside the nozzle body. A first toothed ring is fixedly connected to the top outer wall of the atomizing tooth. The first toothed ring meshes with the two secondary gears. A main gear is fixedly connected to one end of the two rotating shafts located outside the nozzle body.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. The electrostatic generator of this nozzle charges the droplets, enhancing the electrostatic attraction between the droplets and the plant or the surface of the object being sprayed. Compared with traditional nozzles, the droplets adhere more firmly, reducing waste caused by drifting and slipping, improving the utilization rate of pesticides, paints and other materials, reducing costs and reducing environmental pollution.

[0016] 2. The two-stage atomization using pressure atomizing nozzles and rotating atomizing discs ensures more uniform droplet size, avoiding localized over-dense or under-dense droplets.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a high-uniformity electrostatic mist-dispersing nozzle structure. (Refer to...) Figure 1-4 A high-uniformity electrostatic misting nozzle structure includes a nozzle body 1, which is cylindrical with a liquid inlet at one end and a mist outlet at the other end, and has an internal mounting cavity for mounting atomizing components.

[0024] The atomizing assembly includes a pressure atomizing nozzle 21 and a rotating atomizing disk 8. The pressure atomizing nozzle 21 is installed at the liquid inlet of the nozzle body 1. The liquid enters the pressure atomizing nozzle 21 through the liquid inlet and is initially atomized under pressure. The rotating atomizing disk 8 is rotatably connected to the inner wall of the nozzle body 1 through a mounting ring 9 and is opposite to the liquid outlet direction of the pressure atomizing nozzle 21. The rotating atomizing disk 8 is driven to rotate by a drive mechanism outside the nozzle body 1. Its surface is provided with multiple inclined atomizing teeth 10. When the initially atomized liquid is sprayed onto the rotating atomizing disk 8, it is further refined and dispersed under the action of the atomizing teeth 10, thereby improving the atomization uniformity.

[0025] The outer wall of the nozzle body 1 is threaded, and the mounting base 2 and the nozzle cover 3 are connected by the thread. The mounting base 2 and the nozzle cover 3 abut against each other. The atomizing port of the nozzle body 1 passes through the mounting base 2 and is located inside the nozzle cover 3. An electrostatic generating component is installed on the inner wall of the nozzle cover 3.

[0026] The electrostatic generator assembly includes an inner electrode ring 4 and an electrode ring 7. The inner electrode ring 4 is fixedly connected to the bottom outer wall of the nozzle cover 3. Its inner hole expands downward in a funnel shape at the bottom. This design helps to expand the diffusion range of the droplets. The electrode ring 7 is installed between the inner electrode ring 4 and the nozzle cover 3. A slot 5 is provided on the bottom inner wall of the nozzle cover 3. A retaining ring 6 is engaged with the inner wall of the slot 5. The electrode ring 7 is fixedly connected to the outer wall of the retaining ring 6. This engagement method facilitates the installation and removal of the electrode ring 7. When the electrostatic generator assembly is working, it charges the droplets, increasing the adsorption and coverage of the droplets.

[0027] The drive mechanism includes two rotating shafts 14 symmetrically rotatably connected to the outer wall of the nozzle body 1 via bushings 13. A secondary gear 15 is fixedly connected to one end of each rotating shaft 14 inside the nozzle body 1. A first gear ring 12 is fixedly connected to the top outer wall of the rotating atomizing disc 8, meshing with the two secondary gears 15. A main gear 16 is fixedly connected to one end of each rotating shaft 14 outside the nozzle body 1. The drive mechanism also includes a second gear ring 18, a bracket 19, and a servo motor 20. The second gear ring 18 is rotatably connected to the outer wall of the nozzle body 1 via a bearing ring 17, meshing with the two main gears 16. The bracket 19 is fixedly connected to the top outer wall of the mounting base 2. The servo motor 20 is fixedly mounted on the outer wall of the bracket 19, with its output shaft end penetrating the bracket 19 and fixedly connected to the shaft of one of the main gears 16. When the servo motor 20 starts, it drives the rotating atomizing disc 8 to rotate through the transmission of the main gear 16, secondary gear 15, and first gear ring 12.

[0028] Multiple balls 11 are rolled on the contact surface between the rotating atomizing disc 8 and the mounting ring 9. The multiple balls 11 are evenly distributed in a circumferential array with equal spacing between the rotating atomizing disc 8 and the mounting ring 9, which reduces the friction when the rotating atomizing disc 8 rotates and improves the smoothness of rotation.

[0029] The implementation principle of a high uniformity electrostatic misting nozzle structure in this application embodiment is as follows: When the nozzle starts to work, the liquid first flows into the pressure atomizing nozzle 21 from the liquid inlet of the nozzle body 1. Under the action of pressure, the liquid is constrained and accelerated by the flow channel and sprayed out at high speed from the small hole of the nozzle. During the high-speed spraying process, the liquid undergoes violent friction and collision with the surrounding air, thereby being initially atomized into smaller droplets. These initially atomized droplets have a certain speed and direction and are sprayed toward the rotating atomizing disk 8.

[0030] As the liquid begins to atomize, the servo motor 20 is started, and the output shaft of the servo motor 20 begins to rotate. Since the end of its output shaft passes through the bracket 19 and is fixedly connected to the shaft of one of the main gears 16, it will drive the main gear 16 connected to it to rotate.

[0031] The rotation of the main gear 16 is transmitted to the second gear ring 18 and the other main gear 16 through gear meshing. The second gear ring 18 meshes with the two main gears 16, which plays the role of transmitting power and stabilizing transmission. At the same time, the two main gears 16 are respectively fixed to one end of the two rotating shafts 14 located outside the nozzle body 1. Therefore, the rotation of the main gear 16 will drive the rotating shaft 14 to rotate around the bushing 13. The bushing 13 is symmetrically rotated and connected to the outer wall of the nozzle body 1, providing stable support and a basis for the rotation of the rotating shaft 14.

[0032] A secondary gear 15 is fixedly connected to one end of the rotating shaft 14 inside the nozzle body 1. As the rotating shaft 14 rotates, the secondary gear 15 will also rotate synchronously. A first toothed ring 12 is fixedly connected to the top outer wall of the rotating atomizing disk 8. The first toothed ring 12 meshes with two secondary gears 15. Therefore, the rotation of the secondary gear 15 will drive the rotating atomizing disk 8 to rotate on the mounting ring 9 through the meshing transmission with the first toothed ring 12. Multiple balls 11 are rolled on the contact surface between the rotating atomizing disk 8 and the mounting ring 9. These balls 11 are evenly distributed in a circumferential array with equal spacing. When the rotating atomizing disk 8 rotates, the balls 11 can greatly reduce the friction between the rotating atomizing disk 8 and the mounting ring 9, making the rotation smoother.

[0033] When the initially atomized droplets are sprayed onto the rotating atomizing disk 8, they will collide with multiple inclined atomizing teeth 10 on the surface of the rotating atomizing disk 8. Since the rotating atomizing disk 8 is rotating at high speed, the atomizing teeth 10 also move at high speed. When the droplets collide with the atomizing teeth 10, they will be further refined and dispersed under the action of the atomizing teeth 10. The inclined atomizing teeth 10 can change the direction and speed of the droplets, causing the droplets to be torn into smaller droplets during the collision process, thereby realizing the secondary atomization of the droplets and greatly improving the uniformity of atomization.

[0034] After secondary atomization, the droplets continue to move towards the mist outlet of the nozzle cover 3. At this time, the electrostatic generator is activated, and the electrode ring 7 and the inner electrode ring 4 begin to work. The inner electrode ring 4 is fixedly connected to the bottom outer wall of the nozzle cover 3. Its inner hole expands downward in a funnel shape at the bottom. This structural design helps to expand the diffusion range of the droplets. The electrode ring 7 is installed between the inner electrode ring 4 and the nozzle cover 3 and is fixedly engaged with the groove 5 on the bottom inner wall of the nozzle cover 3 by the retaining ring 6.

[0035] When the droplets pass near the electrode ring 7 and the inner electrode ring 4, they become charged under the influence of the electrostatic field. After the charged droplets are ejected from the nozzle 3, they interact with each other due to the presence of the charge, and also attract each other to the surrounding objects. This allows the droplets to adhere better to the surface of the target object, increasing the adsorption and coverage of the droplets, thereby improving the spraying effect.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
