Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically to a multi-head dual-fluid atomizer with replaceable nozzles. Background Technology

[0002] In current agricultural spraying operations, traditional single-nozzle atomizers have two major drawbacks:

[0003] 1. Uneven coverage: The spray range of a single nozzle is limited, which can easily lead to blind spots in the spraying process, resulting in inconsistent pesticide application to crops and affecting the overall effectiveness.

[0004] 2. Poor nozzle compatibility: Most existing dual-fluid atomizer nozzles are fixed structures, making it impossible to quickly change nozzles according to the characteristics of the agent or operational requirements (droplet size, flow rate). Replacing the nozzles requires stopping the machine and disassembling the entire unit, which is inefficient.

[0005] Therefore, there is an urgent need for a dual-fluid atomizer that combines the functions of uniform atomization from multiple nozzles with easy replacement. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a multi-head dual-fluid atomizer with replaceable nozzles. Through a circumferential multi-nozzle layout and a pressure-stabilizing and flow-dividing structure, it eliminates spray dead zones and improves atomization uniformity. The modular nozzle assembly design supports rapid nozzle replacement under different working conditions. The independent dual-fluid channels and buffer chamber ensure the stability of fluid supply to each nozzle.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A multi-head dual-fluid atomizer with replaceable nozzles, comprising:

[0009] A fluid input connector has a first fluid input end and a second fluid input end on its exterior, and nozzle connection ends on all four sides of its exterior. Inside the fluid input connector are independent first and second fluid flow channels. The first fluid flow channel connects the first fluid input end and the nozzle connection end, and the second fluid flow channel connects the second fluid input end and the nozzle connection end. Inside the fluid input connector is a storage cavity, which is connected to both the second fluid input end and the second fluid flow channel.

[0010] The nozzle assembly is detachably connected to the nozzle connection end and is connected to the first fluid flow channel and the second fluid flow channel respectively.

[0011] Furthermore, the nozzle assembly includes an outer nozzle and an inner nozzle; the inner nozzle is nested inside the outer nozzle and has a first fluid output channel communicating with a first fluid flow channel and a second fluid output channel communicating with a second fluid flow channel.

[0012] Furthermore, the nozzle assembly also includes an upper nozzle, which is nested on the upper surface of the outer nozzle and forms a cavity with the inner nozzle. This cavity communicates with the second fluid output channel. The upper nozzle is provided with a second fluid output hole that penetrates its body and a through hole for avoiding the first fluid output channel.

[0013] Furthermore, the inner diameter of the second fluid output orifice is smaller than the inner diameter of the second fluid output channel.

[0014] Furthermore, the nozzle connection end is detachably connected to the external nozzle via a threaded or plug-in connection.

[0015] Furthermore, a sealing element is provided between the nozzle connection end and the nozzle assembly; the sealing element is located between the inner wall of the nozzle connection end and the outer wall of the inner nozzle, and has openings for the first fluid and the second fluid to pass through respectively.

[0016] Furthermore, the second fluid output channel is located inside the outer nozzle, and the inner nozzle is detachably installed inside the second fluid output channel; the inner nozzle is provided with a fluid inlet communicating with the second fluid output channel and a fluid output channel inside it.

[0017] Furthermore, the inner nozzle and the outer nozzle are connected by threads.

[0018] Furthermore, a sealing element is provided between the nozzle connection end and the connection end face of the external nozzle, and the sealing element has independent through holes for the first fluid and the second fluid to pass through respectively.

[0019] Compared with existing technologies, this patented technology achieves the following beneficial effects: The core lies in its multi-head design combined with independent dual-fluid channels and a pressure-stabilizing chamber for the second fluid. Multiple nozzles operate simultaneously, and the circumferential layout eliminates spray dead zones; independent channels ensure a stable and isolated dual-fluid supply to each nozzle; and the pressure-stabilizing chamber balances the air pressure of each nozzle. These three elements work synergistically to fundamentally solve the core problem of uniform spraying over large areas, resulting in wider and more even spray coverage. Users can replace one or more nozzles at any time according to specific needs or to address nozzle malfunctions, without needing to replace the entire unit. This allows a single atomizer to flexibly adapt to various application scenarios and operating conditions, improving versatility and economy. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1: See Figure 1-3 , Figure 7 As shown, this embodiment provides a multi-head dual-fluid atomizer with replaceable nozzles, including:

[0030] The fluid input connector 1 has a first fluid input end 11 and a second fluid input end 12 on its exterior, and nozzle connection ends 10 on all four sides. It employs a multi-nozzle layout to achieve wide-area uniform coverage. The design of having nozzle connection ends 10 on all four sides allows the atomizer to simultaneously connect to and drive multiple nozzle assemblies 2. These nozzles are distributed circumferentially around the fluid input connector 1, significantly expanding the spray coverage area. The simultaneous operation of multiple nozzles, with their overlapping spray areas, effectively overcomes the problems of uneven coverage and dead zones associated with single nozzles, making it particularly suitable for scenarios requiring large-area uniform spraying.

[0031] The fluid input connector 1 has independent first fluid flow channels 13 and second fluid flow channels 14. The first fluid flow channel 13 connects the first fluid input end 11 and the nozzle connection end 10, and the second fluid flow channel 14 connects the second fluid input end 12 and the nozzle connection end 10. Before entering the nozzle assembly 2, the first and second fluids have completely independent and non-interfering channels within the fluid input connector 1. The fluid input connector 1 also has a storage cavity 15, which connects to both the second fluid input end 12 and the second fluid flow channel 14. The storage cavity 15 is located in the second fluid input channel and connects to all the second fluid flow channels 14 leading to the nozzle connection end 10. This cavity mainly serves as a buffer and pressure stabilizer. As a common chamber, it helps to balance the pressure of the second fluid distributed to each nozzle connection end 10, reducing the problem of uneven air volume between different nozzles due to differences in flow path length or resistance, and further improving the atomization uniformity of multiple nozzles. When the instantaneous flow demand increases, the gas stored in the cavity 15 can be replenished briefly, which helps to maintain the relative stability of the system pressure.

[0032] The nozzle assembly 2 is detachably connected to the nozzle connection end 10. The nozzle assembly 2 includes an outer nozzle 21 and an inner nozzle 22. The inner nozzle 22 is nested inside the outer nozzle 21 and has a first fluid output channel 221 that connects to the first fluid flow channel 13 and a second fluid output channel 222 that connects to the second fluid flow channel 14. Different models or specifications of nozzle assemblies 2 can be quickly replaced according to different operational needs or different fluid properties, greatly improving the adaptability and versatility of the atomizer.

[0033] The nozzle assembly 2 in this embodiment also includes an upper nozzle 23, which is nested on the upper surface of the outer nozzle 21 and forms a cavity 231 with the inner nozzle 22. The cavity 231 communicates with the second fluid output channel 222. The upper nozzle 23 is provided with a second fluid output hole 232 penetrating its body and a through hole 233 for avoiding the first fluid output channel 221. The upper nozzle 23 is nested in the outer nozzle 21 to form a nested structure, which saves space and enhances the overall rigidity. The cavity can also serve as a transition zone for the second fluid delivery, which can buffer fluid pressure fluctuations and thus improve spray quality. The through hole 233 is used to avoid the first fluid output channel 221, ensuring that the first fluid path is not obstructed.

[0034] The inner diameter of the second fluid output orifice 232 is smaller than the inner diameter of the second fluid output channel 222. By reducing the orifice size, the Venturi effect is used to accelerate the flow rate of the second fluid, generating a high-speed shearing effect at the outlet, promoting fluid atomization and achieving a finer atomization effect.

[0035] A sealing element 3 is provided between the fluid input connector 1 and the nozzle connection assembly 2. The sealing element 3 is located between the inner wall of the fluid input connector 1 and the outer wall of the inner nozzle 22, and has a through-hole 31 for the first fluid and the second fluid to pass through. The sealing element 3 is placed in the radial gap, directly sealing the contact surface between the fluid input connector 1 and the inner nozzle 22, effectively preventing fluid leakage.

[0036] Example 2: See Figure 4-7 As shown, this embodiment provides a multi-head dual-fluid atomizer with replaceable nozzles, including: a fluid input connector 1 and a nozzle assembly 2. The nozzle assembly 2 includes an outer nozzle 21 and an inner nozzle 22. The outer nozzle 21 is connected to the fluid input connector 1 by a threaded or plug-in method. The outer nozzle 21 has a first fluid output channel 221 and a second fluid output channel 222 inside. The inner nozzle 22 is detachably disposed in the second fluid output channel 222. The inner nozzle 22 has a fluid input port 23 communicating with the second fluid output channel 222 and a fluid output channel 24 inside. The first fluid input channel 11 communicates with the first fluid output channel 221, and the second fluid input channel 12 communicates with the second fluid output channel 222.

[0037] A sealing element 3 is provided between the connection end face of the fluid input connector 1 and the external nozzle 21. The sealing element 3 has independent perforations 32 for the first fluid and the second fluid to pass through respectively. The sealing element 3 is placed at the end face connection to seal the entire interface and effectively prevent fluid leakage at the connection point. The independent perforations 32 ensure that the two fluids remain separated when passing through the sealing element 3.

[0038] This embodiment is basically the same as Embodiment 1, except that: the second fluid output channel 222 is located inside the outer nozzle 21, and the inner nozzle 22 is detachably installed inside the second fluid output channel 222; the inner nozzle 22 has a fluid inlet 24 communicating with the second fluid output channel 222 and an internal fluid output channel 25. The second fluid output channel 222 is located in the outer nozzle 21, and the inner nozzle 22 is detachably installed inside the second fluid output channel 222. The inner nozzle 22 has a fluid inlet 24 communicating with the second fluid output channel 222 and an internal fluid output channel 25. This design reduces structural complexity and improves the ease of assembly between the inner nozzle 22 and the outer nozzle 21. The inner nozzle 22 is connected to the second fluid output channel 222 of the outer nozzle 21 by a threaded connection. From the overall structure, it can be seen that the structure achieving the same effect is simpler than that of Embodiment 1.
