[0002] Essential oils are often used in life to improve the surrounding environment or for medical treatment; such as for sterilization, disinfection, changing the environmental odor, etc. When using essential oils, an atomizer is used to atomize the essential oils for easy absorption by people or for easy diffusion into the environment.

[0003] Currently, an atomization core is generally provided in an atomizer. The main principle of the atomization core for atomizing a liquid is to converge the liquid and gas at the same place, use the high-pressure gas generated by an air pump to disperse the liquid, and at the same time use a negative pressure environment to continuously transport the liquid to the atomization port. However, when the existing atomization core atomizes the liquid, the airway and the liquid channel cannot be completely blocked, resulting in unstable air pressure at the atomization port, and thus uneven atomization particles. This will cause more large-particle sprays to flow out of the atomization port, resulting in waste. Summary of the Utility Model

[0045] The present utility model provides a spiral atomizing core 100, as Figures 1 to 4As shown in the figure, it includes: a first core body 1, a second core body 2, and a gasket 14. The first core body 1 has an air inlet 11 and a liquid inlet 171. A liquid channel 131 and an air channel 121 are arranged inside the first core body 1. The air inlet 11 is communicated with the air channel 121, and the liquid inlet 171 is communicated with the liquid channel 131. The second core body 2 is installed on the first core body 1. A first liquid tank 21 is formed inside the second core body 2. The first end of the first liquid tank 21 is communicated with the liquid channel 131. A first air tank 16 is formed between the second core body 2 and the first core body 1. The first end of the first air tank 16 is communicated with the air channel 121. The second end of the first air tank 16 is arranged close to the second end of the first liquid tank 21 and forms an atomizing port 15. The gasket 14 is sleeved outside the second core body 2, and both ends of the gasket 14 are respectively abutted against the first core body 1 and the second core body 2. Specifically, the gas of the air pump enters into the air channel 121 from the air inlet 11, and the liquid of the straw enters into the liquid channel 131 from the liquid inlet 171. The air channel 121 and the liquid channel 131 are completely blocked. The gas in the air channel 121 flows to the first air tank 16, and the liquid in the liquid channel 131 flows to the first liquid tank 21. The second end of the first air tank 16 is close to the second end of the first liquid tank 21. The second end of the first air tank 16 is the air outlet 26, and the second end of the first liquid tank 21 is the liquid outlet 25. The high-pressure gas at the air outlet 26 blows away the essential oil at the liquid outlet 25, atomizes the essential oil at the atomizing port 15, and makes the area near the atomizing port 15 in a negative pressure state. In order to balance the pressures at the liquid inlet 171 and the liquid outlet 25 of the atomizing core 100, the negative pressure at the liquid outlet 25 will cause the atomizing core 100 to continuously suck the essential oil at the bottom of the straw, so that the essential oil is continuously transported to the liquid outlet 25, thereby completing the atomization of the essential oil. A gasket 14 is sleeved on the outer wall of the second core body 2. The gasket 14 is arranged between the second core body 2 and the first core body 1. The second core body 2 squeezes the gasket 14 during the installation process. The gasket 14 is used to correct the tolerance between the second core body 2 and the first core body 1, eliminate the gap between the second core body 2 and the first core body 1, thereby preventing the gas in the first air tank 16 from flowing into the liquid channel 131, improving the stability of the air pressure in the first air tank 16, avoiding the atomization of the atomizing port 15 to produce larger particle sprays, and avoiding the waste of essential oil.

[0046] In some embodiments, such as Figure 3As shown in the figure, the second core body 2 includes a spiral part 22 and a sealing cover 28. The spiral part 22 is snap-connected to the first core body 1. The sealing cover 28 is installed between the spiral part 22 and the first core body 1. The outer wall of the sealing cover 28 abuts against the inner wall of the first core body 1, and the inner wall of the sealing cover 28 abuts against the outer wall of the spiral part 22. There are a first abutting surface 284 and a second abutting surface 285 between the inner wall of the sealing cover 28 and the spiral part 22, and the first abutting surface 284 is perpendicular to the second abutting surface 285. Specifically, the sealing cover 28 is used to seal the opening of the first air groove 16 and guide the high-pressure gas to flow between the spiral part 22 and the sealing cover 28, so that the high-pressure gas flows to the atomizing port 15. Moreover, when sealing the first air groove 16, the sealing cover 28 restricts the movement of the spiral part 22 on the first core body 1, improving the stability of the spiral part 22 on the first core body 1. The first abutting surface 284 and the second abutting surface 285 are perpendicularly arranged, and the sealing cover 28 and the spiral part 22 can be set as a cylindrical structure, which is convenient for processing.

[0047] Preferably, as Figure 3 shown in the figure, there is also a third abutting surface between the sealing cover 28 and the first core body 1, increasing the stability between the spiral part 22 and the first core body 1. Specifically, by installing the sealing cover 28, both sides of the sealing cover 28 respectively squeeze the inner wall of the first core body 1 and the outer wall of the spiral part 22, and frictional resistance is generated between the sealing cover 28 and the first core body 1 and the spiral part 22 respectively, and this frictional resistance improves the stability of the spiral part 22 on the first core body 1.

[0048] Preferably, as Figure 5 and Figure 6 shown in the figure, the second core body 2 has six abutting blocks 23. The abutting blocks 23 are installed outside the spiral part 22, and the six abutting blocks 23 are spaced circumferentially and equidistantly on the spiral part 22. A first air groove 16 is formed between the outer wall of the abutting block 23, the outer wall of the spiral part 22, and the inner wall of the sealing cover 28. Specifically, the abutting block 23 is used to abut against the inner wall of the sealing cover 28, increasing the contact area between the spiral part 22 and the sealing cover 28, thereby improving the stability of the spiral part 22 and the sealing cover 28. Moreover, by arranging the six abutting blocks 23 at intervals, the outer wall of the spiral part 22 has six first air grooves 16, and the outlet ends of the six first air grooves 16 converge at the atomizing port 15, atomizing the essential oil at the atomizing port 15.

[0049] Preferably, as Figure 3 and Figure 7As shown, the sealing cover 28 includes a first cover body 281 and a second cover body 282. The second cover body 282 is installed on the first cover body 281. The outer diameter of the first cover body 281 is greater than that of the second cover body 282. The second cover body 282 is disposed between the first core body 1 and the spiral part 22. The first cover body 281 has an outlet 283, and the outlet 283 communicates with the atomizing port 15. Specifically, the first cover body 281 is used to be disposed at the end of the first core body 1, and the second cover body 282 is used to limit the movement of the spiral part 22 and seal the gap between the spiral part 22 and the first core body 1, so as to guide the high-pressure gas in the first air groove 16 to flow towards the atomizing port 15, and guide the essential oil in the first liquid groove 21 to flow towards the atomizing port 15.

[0050] Preferably, as Figure 3 and Figure 4 shown, the second core body 2 further has a conical part 27. An inverted conical second liquid groove 271 is formed in the conical part 27. The conical part 27 is installed on the spiral part 22. The largest end of the second liquid groove 271 communicates with the first liquid groove 21, and the smallest end of the second liquid groove 271 communicates with the atomizing port 15. Specifically, the second liquid groove 271 is used to communicate with the first liquid groove 21. The second liquid groove 271 is in an inverted conical shape. The second liquid groove 271 is used to reduce the flow rate of the first liquid groove 21 flowing towards the atomizing port 15, so that the essential oil flowing from the spiral part 22 towards the atomizing port 15 is in the form of liquid droplets, reducing the liquid flow rate at the atomizing port 15. The high-pressure gas acts on the essential oil at the atomizing port 15, and each drop of essential oil flowing from the second liquid groove 271 towards the atomizing port 15 can be dispersed and form a smaller particle essential oil spray.

[0051] Preferably, there is an air duct 272 between the outer wall of the conical part 27 and the inner wall of the first cover body 281. The air duct 272 is used for the high-pressure gas in the second air groove 24 to pass through, so that the high-pressure gas acts on the atomizing port 15. The outer wall of the conical part 27 is in an arc-shaped slope, which plays a guiding role for the high-pressure gas.

[0052] In some embodiments, as Figure 5 shown, the outer wall of the spiral part 22 has at least one second air groove 24. The first end of the second air groove 24 communicates with the first air groove 16, and the second end of the second air groove 24 communicates with the atomizing port 15. The second air groove 24 or its extension line deviates from the central axis of the spiral part 22. Specifically, the gas passes through the first air groove 16 and the second air groove 24 from the air inlet 11. The second air groove 24 is used to reduce the flow rate of the high-pressure gas entering the atomizing port 15 and increase the gas flow velocity. The high-pressure gas is sprayed towards the atomizing port 15 after being accelerated by the second air groove 24, improving the atomization efficiency and making the smaller particle spray ejected from the atomizing port 15.

[0053] Preferably, as Figure 5 and Figure 6As shown, there are multiple second air grooves 24, and the multiple second air grooves 24 are arranged around the atomizing port 15. The inlet end of the second air groove 24 is arranged on the side wall of the spiral part 22, the outlet end of the second air groove 24 is arranged on the end face of the spiral part 22, the inlet end of the second air groove 24 is communicated with the first air groove 16, the outlet end of the second air groove 24 is close to the atomizing port 15 and is communicated with the second end of the first liquid groove 21. Specifically, by using multiple second air grooves 24, the high-pressure gas in the first core 1 converges through the multiple second air grooves 24. After passing through the second air grooves 24, the high-pressure gas is accelerated. The gas in the first core 1 converges through the inlet end of the second air groove 24, and then uniformly flows towards the outlet end of the second air groove 24 and sprays towards the atomizing port 15, so as to increase the instantaneous speed of the atomizing port 15, enabling the spiral part 22 to have the function of accelerating the gas flow rate. The high-pressure gas of the multiple second air grooves 24 uniformly sprays towards the atomizing port 15, impacting the liquid droplets at the liquid outlet 25, and further improving the atomizing efficiency of the atomizing port 15.

[0054] In some embodiments, as Figure 2 and Figure 3 shown, the first core 1 includes a first main body part 12, a second main body part 13, and a connecting block 18. There is a chamber in the first main body 12, and a liquid passage 131 is formed in the second main body 13; the second main body 13 is arranged in the chamber, and the second main body 13 is fixed to the inner wall of the first main body part 12 through the connecting block 18; a third air groove 19 is formed between the inner wall of the first main body part 12 and the outer wall of the second main body part 13, and the third air groove 19 is communicated with the first air groove 16. Specifically, by arranging the first main body 12 and the second main body 13, the liquid passage 131 is arranged in the second main body 13, and the air passage 121 is arranged between the first main body 12 and the second main body 13, so that the liquid passage 131 and the air passage 121 can be separated. Moreover, the second main body part 13 is fixed to the first main body 12 through four connecting blocks 18, improving the stability between the first main body 12 and the second main body 13; the high-pressure gas at the air inlet 11 flows into the first air groove 16 through the third air groove 19, and the high-pressure gas is shunted and then converges and accelerates through the multiple second air grooves 24.

[0055] Preferably, as Figures 1 to 3As shown in the figure, the first core body 1 further has a third main body portion 17. The third main body portion 17 is installed on the side wall of the first main body 12. A channel 172 is provided in the third main body portion 17. The channel 172 is bent. The first end of the channel 172 communicates with the liquid channel 131, and the second end of the channel 172 is the liquid inlet 171; the liquid inlet 171 is arranged in the opposite direction to the air inlet 11. Specifically, the atomization core 100 is generally installed in the atomization cover. The space in the atomization cover is limited, and the container bottle is below the atomization cover. Therefore, in order to facilitate the installation of the straw and the atomization core 100, by providing the third main body portion 17, the position of the liquid inlet 171 is changed, and the position of the liquid inlet 171 is set more flexibly; and the direction of the air inlet 11 is opposite to the direction of the liquid inlet 171, which is convenient for transporting high-pressure gas and essential oil from the upper and lower ends of the atomization core 100 respectively.

[0056] The present utility model also proposes an atomizer, including the above-mentioned spiral atomization core 100; installing the atomization core 100 in the atomizer improves the stability of the atomizer in atomizing essential oil, and moreover, the structure of the atomization core 100 is simple and easy to process and install.

[0057] It should be noted that after the first core body 1 and the second core body 2 of the spiral atomization core 100 are separated by the gasket 14, the high-pressure gas of the first core body 1 is prevented from entering the second core body 2, improving the air pressure stability of the atomization port 15; moreover, when the first core body 1 is acted on by the high-pressure gas, the vibration potential energy generated is absorbed by the gasket 14, reducing the noise generated by the vibration of the atomization core 100.

[0058] When citing the drawings for explanation, new features that appear are described; in order to avoid the description being not concise enough due to repeated citation of the drawings, features that have been described clearly are not cited in the drawings one by one.

The purpose is to make the public understand the disclosed content of the present utility model more thoroughly and comprehensively, and not to limit the protection scope of the present utility model thereby.
