The air outlet and liquid outlet are positioned correspondingly, ensuring that the air outlet direction and liquid outlet direction are at right angles or acute angles to enhance the mixing efficiency of airflow and liquid, guaranteeing uniform atomized particle size. This further optimizes the structure of the atomizing core, achieving a more efficient and uniform atomization effect.
[0005] This utility model provides an atomizing core, comprising:
[0006] A first shell portion, the interior of which is provided with a gas chamber, and the first shell portion is provided with an air outlet communicating with the gas chamber, the diameter of which is between 0.3 mm and 0.6 mm;
[0007] The second shell portion has a liquid chamber inside. The second shell portion has a first inclined surface, a second inclined surface, and a liquid outlet hole communicating with the liquid chamber. The liquid outlet hole is located on the second inclined surface. The first inclined surface is located between the air outlet hole and the second inclined surface. A negative pressure space is formed between the first inclined surface and the air outlet hole. The angle between the liquid outlet direction and the air outlet direction of the air outlet hole is less than or equal to 90°.
[0008] According to the present invention, the center of the liquid outlet hole is offset from the center of the air outlet hole, and the offset direction of the liquid outlet hole is the direction of the air outlet hole closer to the second shell portion.
[0009] According to the present invention, the deviation distance of the liquid outlet hole is between 20% and 30% of the inner diameter of the air outlet hole.
[0010] According to the present invention, an atomizing core is provided in which the first shell portion is located above the second shell portion.
[0011] According to the present invention, the included angle between the first inclined surface and the second inclined surface is between 100° and 102°.
[0012] According to the present invention, the angle between the first inclined surface and the surface of the first shell where the air outlet is located is between 33° and 36°.
[0013] According to the present invention, an atomizing core is provided, wherein the gas chamber includes a first chamber and a second chamber, and the first chamber, the second chamber and the gas outlet are connected sequentially along the gas flow direction;
[0014] The cross-sectional areas of both the first chamber and the second chamber gradually decrease along the gas flow direction. The cross-sectional area of the second chamber is larger than the cross-sectional area of the air outlet and smaller than the cross-sectional area of the first chamber. The taper of the first chamber is greater than the taper of the second chamber.
[0015] This utility model also provides an atomizer, comprising:
[0016] Atomizing cover, wherein the atomizing cover is provided with a mist outlet channel and an air inlet channel;
[0017] As described above, in the atomizing core, the gas chamber is connected to the air intake channel;
[0018] The liquid storage bottle has an atomizing core disposed inside it, forming a mixing chamber between the atomizing core and the liquid storage bottle. The mixing chamber is connected to the mist outlet channel, and the liquid chamber is connected to the interior of the liquid storage bottle.

[0021] This utility model also provides an air conditioner, including the atomizer described above.
[0022] The atomizing core of this utility model embodiment is a two-fluid atomizing core, mainly divided into a first shell and a second shell. Compressed gas enters the gas chamber of the first shell, and aromatherapy essential oil enters the liquid chamber of the second shell. After passing through the gas chamber, the compressed gas is ejected through the air outlet. In the direction of the air outlet, a first inclined surface and a second inclined surface of the second shell are arranged in sequence. The end of the liquid outlet of the second shell is located on the second inclined surface. That is, after the compressed gas is ejected from the air outlet, the high-pressure gas first contacts the first inclined surface. Under the action of the first inclined surface, the airflow converges, so that a negative pressure space is formed in the area between the air outlet and the first inclined surface. The essential oil ejected through the liquid outlet after passing through the liquid chamber is impacted at high speed to generate atomization.
[0023] The vent diameter is designed to be 0.3mm~0.6mm. High-speed airflow interacts with the liquid through these precise vents, shearing the liquid into micron-sized droplets. The exact diameter can be determined based on factors such as atomized particle size, pump power, and specific requirements. By adjusting the vent size and airflow pressure, the droplet size can be controlled within the micron or nanometer range. The vents are machined with micron-level precision using laser drilling technology to ensure uniform vent size and prevent uneven atomization or clogging. The vent and liquid outlets are positioned correspondingly, ensuring that the airflow and liquid flow directions are at right or acute angles to enhance airflow-liquid mixing efficiency and guarantee uniform atomized particle size. This further optimizes the atomizer core structure, achieving a more efficient and uniform atomization effect. Attached Figure Description

[0036] like Figure 1 and Figure 2 As shown, the atomizing core provided in this embodiment of the present invention includes a first shell 100 and a second shell 200. The first shell 100 has a gas chamber 110 inside and an air outlet 120 communicating with the gas chamber 110. The diameter of the air outlet 120 is between 0.3 mm and 0.6 mm. The second shell 200 has a liquid chamber 210 inside and has a first inclined surface 220, a second inclined surface 230, and a liquid outlet 240 communicating with the liquid chamber 210. The liquid outlet 240 is located on the second inclined surface 230, and the first inclined surface 220 is located between the air outlet 120 and the second inclined surface 230. A negative pressure space 300 is formed between the first inclined surface 220 and the air outlet 120. The angle between the liquid outlet direction of the liquid outlet 240 and the air outlet direction of the air outlet 120 is less than or equal to 90°.
[0037] The atomizing core of this utility model embodiment is a two-fluid atomizing core, mainly divided into a first shell 100 and a second shell 200. Compressed gas enters the gas chamber 110 of the first shell 100, and aromatherapy essential oil enters the liquid chamber 210 of the second shell 200. After passing through the gas chamber 110, the compressed gas is ejected through the air outlet 120. In the air outlet direction of the air outlet 120, a first inclined surface 220 and a second inclined surface 230 of the second shell 200 are arranged in sequence. The end of the liquid outlet 240 of the second shell 200 is located at the second inclined surface 230. That is, after the compressed gas is ejected from the air outlet 120, the high-pressure gas first contacts the first inclined surface 220. Under the action of the first inclined surface 220, the airflow converges, so that the area between the air outlet 120 and the first inclined surface 220 forms a negative pressure space 300, which atomizes the essential oil ejected through the liquid outlet 240 after passing through the liquid chamber 210.
[0038] The diameter of the air outlet 120 is designed to be 0.3mm~0.6mm. High-speed airflow interacts with the liquid through the precise air outlet 120, shearing the liquid into micron-sized droplets. The diameter can be determined based on data from the atomized particle size, pump power, and actual requirements. By adjusting the size of the air outlet 120 and the airflow pressure, the droplet size can be controlled within the micron or nanometer range. The processing precision of the air outlet reaches the micron level, employing laser drilling technology to ensure uniformity of the pore size and avoid uneven atomization or clogging problems. The air outlet 120 corresponds to the liquid outlet 240, ensuring that the air outlet direction and liquid outlet direction are at right angles or acute angles to enhance the mixing efficiency of the airflow and liquid, guaranteeing uniformity of the atomized particle size. This further optimizes the structure of the atomizing core, achieving a more efficient and uniform atomization effect.
[0039] According to one embodiment of the present invention, the center of the liquid outlet 240 is offset from the center of the vent 120, and the offset direction of the liquid outlet 240 is the direction of the vent 120 near the second shell 200.
[0040] In this embodiment, the second shell portion 200 is positioned on one side of the vent 120 of the first shell portion 100, and this position is defined as the first side of the vent 120. The opposite side is defined as the second side of the vent 120. The liquid outlet 240 is actually eccentrically positioned with the vent 120, with the center of the liquid outlet 240 closer to the first side of the vent 120. This eccentric positioning enhances the negative pressure effect generated during airflow discharge, thereby optimizing the hydrodynamic distribution angles of the vent 120 and the liquid outlet 240 and improving the gas-liquid mixing efficiency.
[0041] According to one embodiment of the present invention, the offset distance of the liquid outlet 240 is between 20% and 30% of the inner diameter of the air outlet 120.
[0042] In this embodiment, the offset distance of the liquid outlet 240 is determined to be 20%~30% of the inner diameter of the air outlet 120. After testing, it is the optimal negative pressure value, which results in stronger atomization intensity and better atomization effect, thereby improving the gas-liquid mixing efficiency by more than 20%.
[0043] According to one embodiment of the present invention, the first shell portion 100 is located above the second shell portion 200.
[0044] In this embodiment, the first shell portion 100 and the second shell portion 200 form an atomizing core structure from top to bottom, thereby forming a gas chamber 110 and an air outlet 120 for air to be discharged from top to bottom, and a liquid chamber 210 and an liquid outlet 240 for liquid to be discharged from bottom to top.
[0045] In this embodiment, the air outlet 120 is set vertically downwards, and the liquid outlet 240 is set horizontally. That is, the air outlet 120 sprays air downwards, and the liquid outlet 240 discharges liquid horizontally. This can improve the spray intensity of the air outlet 120, stabilize the liquid discharge speed and uniformity of the liquid outlet 240, and increase the contact area between the airflow and the liquid, thereby improving the atomization effect and atomization strength.
[0046] According to one embodiment of the present invention, the included angle α between the first inclined plane 220 and the second inclined plane 230 is between 100° and 102°.
[0047] In this embodiment, the first inclined surface 220 gradually slopes downward from the first side to the second side of the vent 120, and the second inclined surface 230 gradually slopes upward from the first side to the second side of the vent 120. The extended end of the second inclined surface 230 is connected to the extended end of the first inclined surface 220, thereby forming a protrusion on the second shell 200 located below the vent 120. A liquid outlet hole 240 is provided inside the protrusion.
[0048] The angle α between the first inclined plane 220 and the second inclined plane 230 is 100°~102°. In this embodiment, the angle α is selected as 101.33°.
[0049] According to one embodiment of the present invention, the included angle b between the first inclined surface 220 and the surface of the first shell portion 100 where the vent 120 is located is between 33° and 36°.
[0050] In this embodiment, in order to ensure that the first inclined surface 220 effectively guides and directs the airflow ejected from the air outlet 120 and improves the negative pressure formation effect of the negative pressure space 300, the included angle b between the first inclined surface 220 and the surface formed at the end of the air outlet 120 is designed to be 33°~36°.
[0051] In this embodiment, the included angle b is chosen to be 34.33°.
[0052] According to one embodiment of the present invention, the gas chamber 110 includes a first chamber 111 and a second chamber 112. The first chamber 111, the second chamber 112 and the air outlet 120 are connected sequentially along the gas flow direction. The cross-sectional areas of the first chamber 111 and the second chamber 112 gradually decrease along the gas flow direction. The cross-sectional area of the second chamber 112 is larger than the cross-sectional area of the air outlet 120 and smaller than the cross-sectional area of the first chamber 111. The taper c of the first chamber 111 is larger than the taper d of the second chamber 112.
[0053] In this embodiment, the gas chamber 110 consists of a first chamber 111 and a second chamber 112 from top to bottom. The end of the first chamber 111 is connected to the beginning of the second chamber 112, and the end of the second chamber 112 is connected to the air outlet 120. Both the first chamber 111 and the second chamber 112 are conical cavities, meaning the inner diameter of the gas chamber 110 gradually decreases along the airflow direction. The taper d of the second chamber 112 is smaller than the taper c of the first chamber 111, and the length of the first chamber 111 is greater than the length of the second chamber 112. Therefore, the contraction angle of the first chamber 111 is smaller than that of the second chamber 112.
[0054] The gas chamber 110 is located in the middle of the atomizing core. High-pressure gas is guided into the gas chamber 110 through the air inlet. The gas chamber 110 adopts a tapered gradient design, and the air outlet 120 adopts a tapered tip fine hole design, which effectively reduces the blockage of air impurities in the gas flow within the first shell 100, while ensuring that the residue of fragrance liquid at the air outlet is minimized, reducing the risk of clogging and improving the anti-clogging ability of the atomizing core. By optimizing the structure of the gas chamber 110 and its streamlined design, airflow turbulence is reduced, the kinetic energy utilization rate of the gas is improved, and a highly efficient and stable atomization effect is achieved.
[0055] In one embodiment, the liquid chamber 210 can also be structurally optimized. For example, the liquid chamber 210 can be designed as a streamlined chamber structure that gradually shrinks along the liquid flow direction. The liquid chamber 210 serves as an independent liquid passage within the atomizing core, drawing liquid from the fragrance liquid container and spraying it out through the liquid chamber 210 and the liquid outlet. The liquid chamber 210 adopts a tapered structure to ensure a constant liquid flow rate and avoid uneven liquid supply.
[0056] The atomizer provided by this utility model is described below. The atomizer described below can be referred to in correspondence with the atomizer core described above.
[0057] This utility model embodiment also provides an atomizer, including an atomizing cap, an atomizing core as described in the above embodiment, and a liquid storage bottle. The atomizing cap is provided with a mist outlet channel and an air inlet channel; the gas chamber 110 is connected to the air inlet channel; the atomizing core is disposed inside the liquid storage bottle, and a mixing chamber is formed between the atomizing core and the liquid storage bottle, the mixing chamber is connected to the mist outlet channel, and the liquid chamber 210 is connected to the inside of the liquid storage bottle.
[0058] In this embodiment of the invention, when the air pump is started, high-pressure gas enters the gas chamber 110 of the atomizing core through the air inlet channel on the atomizing core and is ejected from the air outlet. At the same time, the fragrance liquid in the storage bottle is pumped to the liquid chamber 210 of the atomizing core through the pipeline and is ejected from the liquid outlet. Since the atomizing core is located inside the storage bottle, the air hole and the liquid are sprayed out and then mixed in the chamber to form an atomized liquid. The atomized liquid is further dispersed through the mist outlet channel of the atomizing cap and the mixing nozzle to form a fine and uniform fragrance mist.
[0059] In this embodiment, the conical design of the nozzle ensures uniform diffusion of the mist, improving the coverage of the fragrance effect.
[0060] According to one embodiment of the present invention, the first shell 100 is detachably connected to the atomizing cap; the liquid storage bottle is detachably connected to the atomizing cap.
[0061] In this embodiment, the atomizing core is connected to the atomizing cap using a detachable structure, such as a plug-in or snap-fit design. This ensures airtightness between the air intake channel and the gas chamber 110, facilitating maintenance and cleaning and extending service life. The liquid storage bottle is also connected to the atomizing cap using a detachable structure, such as a threaded connection, facilitating the disassembly and replacement of the liquid storage bottle. Thus, the atomizing core, atomizing cap, and liquid storage bottle form a modular design, improving cost-effectiveness.
[0062] The air conditioner provided by this utility model is described below. The air conditioner described below can be referred to in correspondence with the atomizer described above.
[0063] This utility model embodiment also provides an air conditioner, including an atomizer as described in the above embodiment.
[0064] The air conditioner of this utility model embodiment provides an air conditioner with an optimized fragrance device atomizer, which improves the two-fluid atomization fragrance diffusion technology and is especially suitable for fragrance systems matched with floor-standing central air conditioning.
[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
