[0002] The two-fluid nozzle, also known as an air atomizing nozzle, is a nozzle that uses the high-speed flow of compressed air to atomize liquid particles. It combines two fluids, air and liquid, and realizes the atomization of the liquid through a specific nozzle structure. This kind of nozzle usually has independent air inlets and liquid inlets, and can separately control the flow rate and pressure of air and liquid, so as to adjust the spraying effect.

[0003] Most of the existing two-fluid fan nozzles have fixed spraying angles, and it is difficult to adjust the spraying wide angle according to different usage requirements. For some adjustable two-fluid fan nozzles, their spraying angles can mostly only be adjusted within a certain range, and the flexibility is poor. In view of this, we propose an atomizing nozzle structure to solve the above problems. Content of the Utility Model

[0007] Furthermore, the top and bottom of the adjusting plate are respectively attached to the inner top wall and inner bottom wall of the arc-shaped cover. Both adjusting plates are located outside the nozzle and between the two fixing plates.

[0008] Furthermore, an internal thread is provided on the inner wall of the fixing cover, and the lead screw is threadedly connected to the inner wall of the fixing cover through the internal thread.

[0009] Further, two positioning blocks are also fixed on the outer wall of the two-fluid nozzle body, and two extension blocks are fixedly installed on one side of the arc-shaped cover close to the two positioning blocks.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 and Figure 2 , an atomizing nozzle structure, including a two-fluid nozzle body 1, an air inlet pipe 2, a liquid inlet pipe 3 and a spray nozzle 4, and an arc-shaped cover 5 is installed at the end of the two-fluid nozzle body 1.

[0025] Among them, the air inlet pipe 2, the liquid inlet pipe 3 and the spray nozzle 4 are all structural components of the two-fluid nozzle itself.

[0026] Inside the arc-shaped cover 5, an adjusting assembly for adjusting the spraying arc is provided, and the adjusting assembly is used to adjust the fan-shaped wide-angle area of the sprayed water mist.

[0027] Please refer to Figure 3 , the adjusting assembly includes two fixed plates 6 fixedly installed on the inner wall of the arc-shaped cover 5, and two adjusting plates 7 are also rotatably installed on the inner wall of the arc-shaped cover 5. A fixed cover 8 is fixedly installed on the inner wall of the fixed plate 6, a screw rod 9 is threadedly installed on the inner wall of the fixed cover 8, a rotating wheel 10 is fixedly installed at the end of the screw rod 9 away from the arc-shaped cover 5, and one end of the screw rod 9 located inside the arc-shaped cover 5 is rotatably installed with a connecting block 11, and the other end of the connecting block 11 is rotatably connected to the side wall of the adjusting plate 7.

[0028] Among them, by adding an arc-shaped cover 5 on the surface of the two-fluid nozzle, and then adjusting the angles of the two adjusting plates 7 to adjust the fan-shaped wide-angle area of the spray, and rotating the screw rod 9 can adjust the deflection angle of the adjusting plate 7, which is simple and convenient to operate, thereby making the fan-shaped spray wide-angle adjustment of the two-fluid nozzle more flexible and convenient.

[0029] In addition, the top and bottom of the adjusting plate 7 are respectively attached to the inner top wall and inner bottom wall of the arc-shaped cover 5, and both adjusting plates 7 are located outside the spray nozzle 4 and between the two fixed plates 6.

[0030] It is worth noting that the inner wall of the fixing cover 8 is provided with an internal thread, and the screw rod 9 is threadedly connected to the inner wall of the fixing cover 8 via the internal thread.

[0031] See also Figure 4 and Figure 5 In this embodiment, two positioning blocks 13 are fixed to the outer wall of the two-fluid nozzle body 1, and two extension blocks 12 are fixedly installed on the side of the arc cover 5 close to the two positioning blocks 13, and a mounting cover 16 is also fixedly installed on the side of the extension block 12 away from the two-fluid nozzle body 1.

[0032] A limiting assembly for limiting the position of the arc cover 5 is provided between the extension block 12 and the positioning block 13 . The limiting assembly is used to fix the arc cover 5 to the surface of the two-fluid nozzle body 1 .

[0033] In this embodiment, the limiting assembly includes a movable rod 17 extending from the outside of the mounting cover 16 to the inside thereof. One end of the movable rod 17 located inside the mounting cover 16 is fixedly installed with a block 15 that is clamped in the inside of the positioning block 13. A number of springs 18 are also fixedly installed between the inner wall of the mounting cover 16 and the block 15.

[0034] A clamping groove 14 is formed at one end of the positioning block 13 away from the two-fluid nozzle body 1 , and the clamping block 15 is clamped with the positioning block 13 by extending into the clamping groove 14 .

[0035] In addition, the arc cover 5 is fixed to the surface of the two-fluid nozzle body 1. When the block 15 is inserted into the positioning block 13, the arc cover 5 and the two-fluid nozzle body 1 are fixed. When disassembly is required, the movable rod 17 is pulled to disengage the block 15 from the slot 14. When the block 15 is completely out of the slot 14, the positioning block 13 no longer limits the block 15, and the arc cover 5 can be disassembled. The operation is simple and convenient. In this way, for some two-fluid nozzles with fixed spray angles, they can be adjusted by installing an adjustment component when the spray wide angle needs to be adjusted, and can be disassembled when it is not needed.

[0036] At the same time, when the two-fluid nozzle body 1 is damaged, the two-fluid nozzle can be replaced, which can also save production costs.

[0037] In this embodiment, the side of the positioning block 13 close to the arc-shaped cover 5 is inclined, and the side of the clamping block 15 away from the arc-shaped cover 5 is also inclined.

[0038] By setting the side of the positioning block 13 close to the arc-shaped cover 5 to be inclined and the side of the clamping block 15 away from the arc-shaped cover 5 to be inclined, it is convenient for the arc-shaped cover 5 to be docked with the two-fluid nozzle body 1. When connecting the arc-shaped cover 5 and the two-fluid nozzle body 1, as long as the arc-shaped cover 5 is inserted, when the clamping block 15 and the positioning block 13 move in opposite directions, the positioning block 13 will push the clamping block 15 to move into the interior of the mounting cover 16, thereby facilitating the clamping block 15 to be snapped into the interior of the card slot 14 under the elastic force of the spring 18.

[0039] In the use of this embodiment, the arc-shaped cover 5 is fixed to the surface of the two-fluid nozzle body 1. When the clamping block 15 is inserted into the positioning block 13, the arc-shaped cover 5 and the two-fluid nozzle body 1 are fixed. When it is necessary to adjust the spraying wide-angle range, rotate the runner 10 to make the lead screw 9 rotate. When the lead screw 9 rotates, it will move, so as to drive the connecting block 11 to move, and then deflect the adjusting plate 7. By adjusting the angles of the two adjusting plates 7, the fan-shaped wide-angle area of the spraying can be adjusted. The operation is simple and convenient, thereby making the fan-shaped spray wide-angle adjustment of the two-fluid nozzle more flexible and convenient.

[0040] The electrical components mentioned in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer for control, and the existing publicly disclosed electrical connection technologies are not described in detail in the text.

[0041] The above are only the embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
