[0002] As people's living standards continue to improve, the pursuit of quality of life has become a common aspiration. Fragrance diffusers, as devices that generate fragrant atmospheres, have gradually become an indispensable part of people's daily lives. Existing liquid fragrance diffusers generally use ultrasonic generators to produce high-frequency vibrations, causing the fragrance liquid to decompose into tiny bubbles, which then flow and diffuse into the air through their own pipes and nozzles. During use, users need to change different nozzles to achieve different diffusion effects. Existing nozzles are generally connected to pipes by threads, requiring disassembly for replacement. This replacement process is cumbersome, and the pipes lack valve components during replacement. If the machine is not turned off while changing nozzles, the atomized fragrance liquid can easily diffuse freely, affecting the convenience of use. Utility Model Content

Detailed Implementation

[0018] 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.

[0019] Please see Figure 1-3 This embodiment provides a technical solution: a liquid fragrance machine pipeline, including a fragrance liquid delivery pipe 1;

[0020] Fragrance liquid delivery tube 1: A valve stem 2 is slidably connected to the middle of the tube, connecting the lower end of the fragrance liquid delivery tube 1 to the liquid inlet of the liquid fragrance machine. The fragrance liquid delivery tube 1 facilitates the delivery of atomized fragrance liquid. The left end of the valve stem 2 extends out of the fragrance liquid delivery tube 1 and is equipped with a pin 3. A tension spring 4 is movably sleeved on the left end of the outer arc surface of the valve stem 2. The left end of the tension spring 4 is fixedly connected to the outer arc surface of the fragrance liquid delivery tube 1, and the right end of the tension spring 4 is fixedly connected to the outer arc surface of the pin 3. The tension spring 4 drives the valve stem 2 to slide to the left through the pin 3, and the valve stem 2 delivers the fragrance liquid. The flow channel of tube 1 is blocked, thereby restricting the upward flow of the atomized fragrance liquid. The outer arc surface of the pin 3 is rotatably connected to the lever 6. The outer arc surface of the fragrance liquid delivery tube 1 is provided with a first support plate 5. The right end of the first support plate 5 is matched with the middle part of the lever 6. The lever 6 forms a lever structure under the support of the first support plate 5. The lever 6 rotates around the first support plate 5 as the fulcrum and slides relative to it. The lever 6 drives the valve stem 2 to move to the right through the pin 3. The pin 3 stretches the tension spring 4, and the valve stem 2 opens the flow channel of the fragrance liquid delivery tube 1.

[0021] The quick-change device for the nozzle includes a liquid fragrance machine pipe and a second support plate 7. A rotating shaft 8 is located in the middle of the second support plate 7, providing mounting positions for other components. A rotating disk 9 is located at the upper end of the rotating shaft 8. Each of the mounting holes around the upper surface of the rotating disk 9 is equipped with a nozzle 10. Multiple nozzles 10 are fitted to the upper end of the fragrance liquid delivery pipe 1. There are two or more nozzles 10, and the shape and size of the through holes inside the nozzles 10 are different. Changing between different nozzles 10 can produce different diffusion effects. The upper end of the fragrance liquid delivery pipe 1 is fixedly connected to the circular holes on the upper surface of the second support plate 7. A large spring 11 is movably sleeved at the lower end of the outer arc surface of the rotating shaft 8. A positioning ring 12 is provided at the lower end of the rotating shaft 8. The large spring 11 is located between the positioning ring 12 and the second support plate 7. The positioning ring 12 is fitted with the lower end of the lever 6. The rotating disk 9 drives the rotating shaft 8 to move upward, and the rotating shaft 8 drives the positioning ring 12 to move upward. The positioning ring 12 moves upward and separates from the lower end of the lever 6, while simultaneously squeezing the large spring 11. The upper surface of the second support plate 7 is provided with evenly distributed arc-shaped blocks 15. The lower surface of the rotating disk 9 is provided with a rotating ring 13. The lower surface of the rotating ring 13 is provided with evenly distributed arc-shaped grooves 14. The arc-shaped grooves 14 are all movably engaged with the vertically corresponding arc-shaped blocks 15. The turntable 9 drives the arc-shaped groove 14 to rotate via the rotating ring 13. The arc-shaped groove 14 slides relative to the arc-shaped block 15. After the arc-shaped groove 14 and the arc-shaped block 15 are misaligned, they will drive the rotating ring 13 and the turntable 9 to move upward. The number of arc-shaped blocks 15 and arc-shaped grooves 14 are the same as the number of nozzles 10, and the three correspond one-to-one. The turntable 9 drives the nozzles 10 to move. The upper surface of the turntable 9 is provided with a rotating block 16, which rotates the turntable 9. It also includes a sealing gasket 20, which is respectively set on the lower surface of the nozzle 10. The sealing gasket 20 is a silicone sealing gasket to facilitate the sealing connection between the nozzle 10 and the fragrance liquid delivery tube 1. A marker post 17 is slidably connected inside the circular hole on the upper surface of the turntable 9. A positioning piece 19 is provided at the lower end of the marker post 17. A small spring 18 is movably sleeved at the lower end of the outer arc surface of the marker post 17. The small spring 18 is located between the positioning piece 19 and the turntable 9. The lower surface of the positioning piece 19 is slidably connected to the upper surface of the second support plate 7. Under the action of the small spring 18, the positioning piece 19 is always in contact with the second support plate 7 and will slide relative to it. The vertical position of the marker post 17 will not change. Thus, the relative position between the marker post 17 and the turntable 9 can be observed, the vertical position of the turntable 9 can be determined, and thus the position of the nozzle 10 can be determined.

[0022] The working principle of the liquid fragrance machine pipe and nozzle quick-change device provided by this utility model is as follows: During use, the lower end of the fragrance liquid delivery pipe 1 is connected to the liquid supply port of the liquid fragrance machine. The atomized liquid is conveyed upwards along the fragrance liquid delivery pipe 1, and then sprayed out through the vertically corresponding nozzles 10 after the sealing gasket 20 is connected. There are two or more nozzles 10, and the shape and size of the through holes inside the nozzles 10 are different. Changing different nozzles 10 can produce different diffusion effects. When changing the nozzles 10, the rotating block 16 rotates the rotating disk 9. The rotating disk 9 drives the arc groove 14 to rotate through the rotating ring 13. The arc groove 14 slides relative to the arc block 15. After the arc groove 14 and the arc block 15 are misaligned, the rotating ring 13 and the rotating disk 9 will move upwards. The rotating disk 9 drives the rotating shaft 8 to move upwards, and the rotating shaft 8 drives the positioning ring 12 to move upwards. The positioning ring 12 moves upwards and separates from the lower end of the lever 6, simultaneously squeezing the large spring 11. The positioning ring 12 is no longer aligned with the lever. After positioning, the tension spring 4 drives the valve stem 2 to slide to the left via the pin 3. The valve stem 2 blocks the flow channel of the fragrance liquid delivery pipe 1, thereby restricting the upward flow of the atomized fragrance liquid. Then, the rotating block 16 continues to rotate the rotating disk 9, which drives the nozzle 10 to move. The arc block 15 slides relative to the lower surface of the rotating ring 13. After the arc groove 14 aligns with the arc block 15, the rotating disk 9 moves downward under the action of the large spring 11. The rotating disk 9 drives the nozzle 10 and the sealing gasket 20 to move down and connect with the fragrance liquid delivery pipe 1. At the same time, the positioning ring 12 moves down to squeeze the lower end of the lever 6. The lever 6 forms a lever structure under the support of the first support plate 5. The lever 6 rotates around the first support plate 5 and slides relative to it. The lever 6 drives the valve stem 2 to move to the right via the pin 3. The pin 3 stretches the tension spring 4, and the valve stem 2 opens the flow channel of the fragrance liquid delivery pipe 1. Then, the vertically corresponding nozzle 10 can spray the fragrance liquid.
