[0001] The invention relates to the technical field of aroma diffusers, in particular to an atomizer and an aroma diffuser. Background Art

[0002] The atomizer generally includes an atomizer core, an atomizer cover, and an atomizer bottle. The atomizer core is mounted on the atomizer cover, and the atomizer cover is mounted on the atomizer bottle. The atomizer core has an atomization position, and the atomizer core is used to atomize essential oils. However, the liquid containing cavity of the atomizer bottle needs to be connected to the outside world to ensure that when the atomizer core atomizes the essential oils, the air pressure in the atomizer bottle is consistent with the outside air pressure to avoid pressure difference.

[0003] During the use of the atomizer, oil leakage may occur after the atomizer is tipped over.

[0060] Embodiment 1

[0061] The present invention proposes an atomizer 2, such as Figures 3 to 6 As shown, it includes: an atomizer bottle 21, an atomizer core 224, and an atomizer cover 20. The atomizer cover 20 is detachably installed on the atomizer bottle 21. A liquid containing cavity 204 is formed in the atomizer bottle 21. The atomizer cover 20 has a first atomizer cavity 202. The atomizer core 224 is installed in the atomizer cover 20. The atomizer core 224 has an atomizing position 2240 arranged in the first atomizing cavity 202. The atomizer core 224 has a liquid inlet 2243. The atomizing position 2240 is connected with the liquid containing cavity 204 through the liquid inlet 2243; the atomizer cover 20 is provided with an air hole, and the first atomizer cavity 202 is connected with the liquid containing cavity 204 through the air hole; the air hole is the only channel for connecting the liquid containing cavity 204 with the outside atmosphere; the aperture of the air hole has a first preset value, and at the first preset value, the liquid in the liquid containing cavity 204 cannot flow out of the air hole.

[0062] Specifically, the aperture of the pore has a first preset value, which defines the specific size of the pore. When the aperture of the pore is reduced to a certain extent, the essential oil liquid has a certain surface tension when flowing into the pore, and a state where a liquid channel and a gas channel coexist cannot be formed in the pore. When the atomizer 2 is tilted and not in operation, the liquid will flood the pore after flowing to the pore, and the liquid may flow out for a short time, but as the liquid flows out of the atomizer 2, due to the small size of the pore, a state where a liquid channel and a gas channel coexist cannot be formed in the pore, and the pore cannot supply liquid and gas circulation at the same time, and the gas in the first atomizing chamber 202 cannot flow from the pore into the liquid containing chamber 204. After a certain volume of liquid in the liquid containing chamber 204 is discharged, a certain pressure difference is generated inside and outside the atomizer 2. Because of the pressure difference, the liquid cannot flow out continuously, thereby achieving the purpose of preventing leakage.

[0063] When the atomizer 2 is continuously working and in a tilted state, because the atomizer core 224 needs to continuously absorb the essential oil in the liquid chamber 204, the air pressure in the liquid chamber 204 is lower than the external air pressure. In order to balance the internal and external pressure difference of the atomizer 2, the air hole will absorb the gas in the first atomizer chamber 202 into the liquid chamber 204, so that the internal and external pressure difference of the atomizer 2 is reduced, so the essential oil in the liquid chamber 204 naturally cannot leak through the air hole. The air hole arranged in this way can improve the problem that the structure used to prevent the leakage of essential oil in the existing atomizer 2 is relatively complicated.

[0064] In addition, if there are multiple pores, the aperture of each pore in the multiple pores also has a second preset value. Figure 6As shown, the air holes include a first air hole 205, a second air hole 206, and a third air hole 208, and the liquid containing chamber 204 is connected with the first atomizing chamber 202 through the first air hole 205; a return air channel 207 and a movable plug 226 are arranged in the atomizing cover 20, and the second air hole 206 and the third air hole 208 are respectively arranged at two ends of the return air channel 207, and the first end of the return air channel 207 is connected with the solution chamber 204 through the second air hole 206, and the second end of the return air channel 207 is connected with the first atomizing chamber 202 through the third air hole 208; the movable plug 226 is movably arranged in the return air channel 207, and the movable plug 226 is arranged close to the third air hole 208. The first air hole 205 is used to communicate with the first atomizing chamber 202, the liquid containing chamber 204 is communicated with the return air channel 207 through the second air hole 206, and the return air channel 207 is communicated with the first atomizing chamber 202 through the third air hole 208; therefore, the liquid containing chamber 204 is communicated with the first atomizing chamber 202 through the first air hole 205 and the third air hole 208. When there is a single air hole, the first preset value is 0.2 mm to 0.8 mm; when there are multiple air holes, such as including the first air hole 205 and the second air hole 206, the second preset value is less than 0.2 mm, and the diameters of the first air hole 205 and the second air hole 206 are smaller among the multiple air holes, and the liquid in the air hole will produce a very large surface tension, so that the liquid cannot flow out continuously.

[0065] Moreover, there is a movable plug 226 in the return air channel 207. When the atomizer 2 is not in operation and the atomizer 2 is in a tilted state, the movable plug 226 will move to the vicinity of the third air hole 208 to block the third air hole 208. After the first air hole 205 is submerged by the essential oil, the essential oil cannot continue to flow out of the first air hole 205 due to the surface tension of the liquid in the first air hole 205. When the atomizer 2 is in operation and the atomizer 2 is in a tilted state, the liquid in the liquid containing chamber 204 is continuously transported to the atomization position 2240, and a pressure difference is generated inside and outside the liquid containing chamber 204. In order to balance the pressure difference, the air in the first atomizing chamber 202 can enter the liquid containing chamber 204 through the first air hole 205, or the air in the first atomizing chamber 202 can also enter the liquid containing chamber 204 through the third air hole 208, the return air channel 207, and the second air hole 206, thereby increasing the efficiency of gas reflux. Since the gas has a certain pressure when it flows back to the third air hole 208 , the pressure may move the movable plug 226 , so that the gas can smoothly pass through the third air hole 208 into the return air channel 207 .

[0066] In addition, by setting the second air hole 206 and the third air hole 208, the movable plug 226 is set in the return air channel 207, and the apertures of the second air hole 206 and the third air hole 208 are both less than 0.2 mm. When the liquid in the liquid containing chamber 204 flows back to the first atomizing chamber 202, the second air hole 206 and the third air hole 208 perform multiple blocking on the liquid, further preventing the liquid from overflowing from the liquid containing chamber 204, and also solving the problem of pressure difference between the inside and outside of the atomizer 2 when the atomizer 2 is in operation.

[0067] Preferably, the inner diameter of the return air channel 207 is greater than the first preset value, the aperture of the third air hole 208 is greater than the first preset value, and the aperture of the third air hole 208 is smaller than the inner diameter of the return air channel 207. Specifically, the inner diameter of the return air channel 207 is greater than the first preset value, so as to facilitate the placement of the movable plug 226 in the return air channel 207; and the aperture of the third air hole 208 is greater than the first preset value, so as to increase the flow rate of the return air of the third air hole 208, so as to enable the air in the first atomizing chamber 202 to quickly flow back to the liquid containing chamber 204 when the atomizer 2 is in operation, so as to prevent the atomizing bottle 21 from being unable to absorb the essential oil in the liquid containing chamber 204 due to the pressure difference.

[0068] In some embodiments, Figure 6 As shown, the atomizer 2 also includes a straw 221 and an air pipe 222, the first end of the straw 221 is installed on the atomizing core 224, and the second end of the straw 221 is arranged at the bottom of the atomizing bottle 21; the air pipe 222 is sleeved on the outside of the straw 221, and the first end of the air pipe 222 is installed at the bottom of the atomizing cover 20, the first end of the air pipe 222 is connected to the first air hole 205, and the second end of the air pipe 222 is arranged at the bottom of the atomizing bottle 21. Specifically, since the first air hole 205 is connected to the air pipe 222, the liquid heights inside and outside the air pipe 222 are consistent. When the atomizer core 224 absorbs the essential oil in the liquid containing chamber 204 through the straw 221, the bottom of the straw 221 is at the bottom of the liquid containing chamber 204, and the liquid in the air pipe 222 is higher than the liquid outside the air pipe 222. Since the first air hole 205 is connected to the air pipe 222, air flows into the air pipe 222 from the first air hole 205, so that the air pipe 222 and the straw 221 produce a siphon effect. The siphon effect can cause the liquid in the air pipe 222 to quickly flow to the outside of the air pipe 222, so that the liquid inside and outside the air pipe 222 are at the same height, thereby filling the liquid at the bottom of the liquid containing chamber 204 in time.

[0069] In some embodiments, Figure 5 As shown, the bottom of the atomizer 2 also has a filter 223, which is installed at the second end of the straw 221. The filter 223 is used to filter impurities in the essential oil to prevent the impurities from moving with the essential oil to the atomization core 224 and prevent the impurities from clogging the atomization core 224.

[0070] Embodiment 2

[0071] The present invention proposes another atomizing cover 20, such as Figures 7 to 11 As shown, it includes: a first cover body 22 and a second cover body 23, the first cover body 22 includes a first limiting column 24 and a second limiting column 25, the first limiting column 24 is sleeved on the outside of the second limiting column 25, and the first end of the first limiting column 24 is fixed to the first end of the second limiting column 25, and the second end of the first limiting column 24 is spaced from the second end of the second limiting column 25; the second cover body 23 includes a third limiting column 231 and a cover plate 232, the third limiting column 231 is installed under the cover plate 232, and the cover plate 232 has a slot 236; the third limiting column 231 is sleeved on the outside of the first limiting column 24, and the inner wall of the third limiting column 231 is abutted against the outer wall of the first limiting column 24, and the second limiting column 25 is snapped into the slot 236.

[0072] Specifically, the first cover body 22 and the second cover body 23 are assembled by snapping, and the slot 236 positions the installation of the first cover body 22. When the second limiting column 25 corresponds to the slot 236, the third limiting column 231 can be sleeved on the outside of the first limiting column 24, or the first limiting column 24 can be sleeved on the outside of the third limiting column 231, thereby improving the efficiency of assembling the first cover body 22 and the second cover body 23. Moreover, when the second limiting column 25 is at least partially inserted into the slot 236 and engaged with the slot 236, the inner wall / outer wall of the third limiting column 231 abuts against the outer wall / inner wall of the first limiting column 24, thereby increasing the connection area between the first cover body 22 and the second cover body 23; at the same time, after the third limiting column 231 abuts against the first limiting column 24, the third limiting column 231 squeezes the first limiting column 24, and the first limiting column 24 generates a reaction force acting on the third limiting column 231, thereby increasing the friction resistance between the first cover body 22 and the second cover body 23, thereby improving the stability of the first cover body 22 and the second cover body 23 after assembly.

[0073] In addition, the third limiting cylinder 231 and the first limiting cylinder 24 are the first connection position after the atomizer cover 20 is assembled, and the slot 236 of the second limiting cylinder 25 and the cover plate 232 is the second connection position after the atomizer cover 20 is assembled. By setting two connection positions; and, the first limiting cylinder 24 is sleeved on the outside of the second limiting cylinder 25, and the first cover body 22 is fixed to the second cover body 23 by the first limiting cylinder 24 and the second limiting cylinder 25, the atomizer cover 20 has different connection positions in the radial direction, further improving the stability of the atomizer cover 20 after assembly.

[0074] In some embodiments, Fig.11 and Fig.12As shown, the second cover body 23 also includes a fourth limiting column 233 and a fifth limiting column 234. The outer diameter of the fifth limiting column 234 is larger than the outer diameter of the fourth limiting column 233. The fourth limiting column 233 and the fifth limiting column 234 are both installed at the lower end of the cover plate 232, and the fourth limiting column 233 is arranged in the fifth limiting column 234. The fourth limiting column 233 and the fifth limiting column 234 are arranged in concentric circles, and a slot 236 is formed between the outer wall of the fourth limiting column 233 and the inner wall of the fifth limiting column 234. Specifically, since the fourth limiting cylinder 233 and the fifth limiting cylinder 234 are arranged in concentric circles, and the fourth limiting cylinder 233 is arranged in the fifth limiting cylinder 234, the slot 236 can be extended along the circumferential direction of the fourth limiting cylinder 233, and any width of the slot 236 remains consistent; when the second limiting cylinder 25 is engaged with the slot 236, the inner wall of the second limiting cylinder 25 is against the outer wall of the fourth limiting cylinder 233, and the outer wall of the second limiting cylinder 25 is against the inner wall of the fifth limiting cylinder 234, thereby increasing the connection area between the first cover body 22 and the second cover body 23 after assembly, thereby further improving the stability of the atomization cover 20 after assembly.

[0075] In some embodiments, Fig.11 and Fig.12 As shown, the height of the fourth limiting cylinder 233 is greater than the height of the fifth limiting cylinder 234, and the bottom of the fourth limiting cylinder 233 is lower than the bottom of the fifth limiting cylinder 234; the outer wall of the fourth limiting cylinder 233 is used to abut against the inner wall of the second limiting cylinder 25. Specifically, by increasing the height of the fourth limiting cylinder 233, the connection area between the second limiting cylinder 25 and the fourth limiting cylinder 233 is increased. When the second limiting cylinder 25 squeezes the outer wall of the fourth limiting cylinder 233 and the inner wall of the fifth limiting cylinder 234 respectively, a large friction resistance will be generated between the second limiting cylinder 25 and the fourth limiting cylinder 233, further improving the stability of the atomizing cover 20 after assembly.

[0076] In some embodiments, Fig.11 and Fig.12As shown, the outer wall of the first limiting cylinder 24 has a first protrusion 241, and the first protrusion 241 is extended along the circumference of the first limiting cylinder 24; the outer wall of the fourth limiting cylinder 233 has a second protrusion 235, and the second protrusion 235 is extended along the circumference of the fourth limiting cylinder 233; the third limiting cylinder 231 is provided with a first limiting groove matched with the first protrusion 241, and the second limiting cylinder 25 is provided with a second limiting groove matched with the second protrusion 235. Specifically, the first protrusion 241 is matched with the first limiting groove, and the second protrusion 235 is matched with the second limiting groove, so as to increase the vertical movement resistance between the first limiting cylinder 24 and the third limiting cylinder 231, and between the second limiting cylinder 25 and the fourth limiting cylinder 233, so as to realize that the limiting structures are provided at two different connection positions of the first cover 22 and the second cover 23. Moreover, the number of the second protrusions 235 can be set to two, and the two second protrusions 235 are arranged along the height direction of the fourth limiting column 233 to further improve the connection stability between the second limiting column 25 and the fourth limiting column 233.

[0077] Preferably, Fig.11 As shown, the first limiting column 24 includes a supporting portion 243 and an abutting portion 244. The abutting portion 244 is mounted on the supporting portion 243. The width of the abutting portion 244 is smaller than the width of the supporting portion 243. The abutting portion 244 is used to abut against the inner wall of the third limiting column 231. Specifically, the width of the supporting portion 243 is larger than the width of the abutting portion 244. The supporting portion 243 is used to support the abutting portion 244, and at the same time, the supporting strength of the first limiting column 24 is also improved to prevent the first limiting column 24 from being squeezed by the third limiting column 231 and causing the first limiting column 24 to break or deform. Moreover, the abutting portion 244 is used to abut against the inner wall of the third limiting column 231, so as to support and fix the third limiting column 231.

[0078] In some embodiments, Fig.10As shown, the atomizer cover 20 also has a support seat 28 and an atomizer core 224. The support seat 28 is installed in the second limiting column 25, and the atomizer core 224 is installed on the support seat 28. The atomizer core 224 has an atomization position 2240; the first cover body 22 also has a top plate 29, and the top plate 29 is installed in the second limiting column 25. A first atomization cavity 202 is formed between the lower end of the top plate 29 and the support seat 28, and the atomization position 2240 is arranged in the first atomization cavity 202. Specifically, the bottom of the second limiting column 25 is used to support or fix the support seat 28, and the support seat 28 is used to install the atomization core 224, so that the atomization position 2240 of the atomization core 224 is set in the first atomization chamber 202, and the first atomization chamber 202 is separated from the cavity 242 of the first cover body 22. After the atomization cover 20 and the atomization bottle 21 are assembled, the cavity 242 is the liquid containing chamber 204 of the atomization bottle 21. Therefore, the particle spray in the first atomization chamber 202 cannot contact the essential oil in the liquid containing chamber 204, thereby preventing the particle spray from being adsorbed by the essential oil.

[0079] In some embodiments, Fig.10 As shown, the cover plate 232 is provided with a spray port 201, and a second atomization chamber 203 is formed between the lower end of the cover plate 232 and the upper end of the top plate 29, and the top plate 29 is provided with a through hole, and the first atomization chamber 202 is connected to the second atomization chamber 203 through the through hole, and the second atomization chamber 203 is connected to the spray port 201. Specifically, during the process of atomizing the essential oil by the atomization core 224, the high-pressure gas of the air pump 4 blows the essential oil away, and forms a particle spray in the first atomization chamber 202, and the particle spray of the first atomization chamber 202 enters the second atomization chamber 203 through the through hole. Among them, due to the limited diffusion distance of the essential oil spray of larger particles, when the particle spray of larger particle size in the first atomization chamber 202 contacts the inner wall of the top plate 29 or the second limiting cylinder 25, it is adsorbed by the wall surface of the top plate 29 and the second limiting cylinder 25, so as to avoid the larger particle spray from flowing out of the spray port 201 and avoid the waste of essential oil. The adsorbed particle spray gathers a certain amount to form liquid essential oil, and flows toward the first air hole 205 , and flows back into the liquid containing cavity 204 through the first air hole 205 .

[0080] This embodiment also provides a fragrance diffuser 100, such as Figures 1 to 5As shown, it includes a housing 1, an atomizing bottle 21, an air pump 4, and the atomizing cover 20 as described above, a mounting cavity is formed in the housing 1, the atomizing cover 20 is mounted on the atomizing bottle 21, the atomizing bottle 21, the atomizing cover 20, and the air pump 4 are all mounted in the mounting cavity, the atomizing cover 20 is connected with the air pump 4, and the atomizing cover 20 is at least partially exposed relative to the housing 1. Specifically, the atomizing bottle 21 is threadedly connected to the atomizing cover 20, the atomizing cover 20 has a straw 221, a first end of the straw 221 is fixed to the liquid inlet 2243 of the atomizing core 224, and a second end of the straw 221 is arranged at the bottom of the atomizing bottle 21. When the high-pressure gas of the air pump 4 is delivered to the air inlet end 209 of the atomizing cover 20 through the airway hose 41, and flows out from the air outlet 2242 after entering the air inlet 2244 of the atomizing core 224, the high-pressure gas will blow away the essential oil at the liquid outlet 2241, and under the action of the high-pressure gas, there is a pressure difference between the air pressure at the liquid outlet 2241 and the air pressure at the second end of the straw 221. Because of the pressure difference, the straw 221 continuously delivers the essential oil in the liquid chamber 204 to the liquid outlet 2241, thereby achieving the purpose of atomizing the essential oil.

[0081] Moreover, the atomizer cover 20 and the atomizer bottle 21 are arranged in the shell 1, most of the structure of the atomizer 2 is hidden in the shell 1, and the atomizer cover 20 is at least partially exposed; when it is necessary to replace or add essential oil, the atomizer cover 20 can be held and the atomizer bottle 21 can be taken out of the shell 1, so as to facilitate the addition of essential oil.

[0082] In some embodiments, Figure 3 As shown, the housing 1 includes a first shell 11, a second shell 12, and a decorative panel 101. The first shell 11 is installed on the second shell 12, and an installation cavity is formed between the inner walls of the first shell 11 and the second shell 12; the decorative panel 101 is installed on the first shell 11 or the second shell 12, and the outer wall of the first shell 11 is at least partially covered by the decorative panel 101. Specifically, the decorative panel 101 is used to cover the outer surface of the first shell 11. When the aroma diffuser 100 is fixed to the wall through the plug assembly 3 for atomization operation, the decorative panel 101 can provide a better decorative effect for the outer surface of the aroma diffuser 100; at the same time, according to the material setting of the decorative panel 101, the tactile comfort of the aroma diffuser 100 can be improved. In other embodiments, the decorative panel 101 can also cover a part of the second shell 12, so that most of the outer surface area of ​​the aroma diffuser 100 is covered or blocked by the decorative panel 101.

[0083] Preferably, Figures 1 to 3 , Fig.15 and Fig.16As shown, the decorative panel 101 includes a first panel 1011, a second panel 1012, and a third panel 1013. The second panel 1012 or the third panel 1013 includes a shielding plate 1014, a first baffle 1015, and a second baffle 1016. The first baffle 1015 is installed at the first end of the shielding plate 1014, and the second baffle 1016 is installed at the second end of the shielding plate 1014. The first baffle 1015 and the second baffle 1016 are both bent. , a first guide groove 1017 is formed between the first stopper 1015 and the inner side of the shielding plate 1014, and a second guide groove 1018 is formed between the second stopper 1016 and the inner side of the shielding plate 1014; the two ends of the first panel 1011 are respectively arranged in the first guide grooves 1017 of the second panel 1012 and the third panel 1013; the first shell 11 or the second shell 12 has a third stopper 111, and the third stopper 111 is arranged in the second guide groove 1018. Specifically, by setting the first guide groove 1017 and the second guide groove 1018, after the first shell 11 and the second shell 12 are assembled, because the first shell 11 or the second shell 12 has the third stopper 111, the second panel 1012 and the third panel 1013 are slidably matched with the third stopper 111 of the housing 1, and the third stopper 111 slides into the second guide groove 1018, so that the first ends of the second panel 1012 and the third panel 1013 are restricted by the third stopper 111. Then, the two ends of the first panel 1011 are respectively inserted into the first guide grooves 1017 of the second panel 1012 and the third panel 1013, and the first panel 1011 will limit the movement of the second ends of the second panel 1012 and the third panel 1013, thereby fixing the first panel 1011, the second panel 1012, and the third panel 1013 on the outer surface of the first shell 11. This installation method is relatively simple and stable, and there is no need to open screw holes in the first shell 11 and the second shell 12, that is, there are no screws on the decorative panel 101, which can increase the appearance of the decorative panel 101.

[0084] It should be noted that in the atomizer cover 20, the third limiting cylinder 231 is abutted against the first limiting cylinder 24, and the second limiting cylinder 25 is engaged with the card slot 236; the card assembly of the atomizer cover 20 is realized, and the connection area between the first cover body 22 and the second cover body 23 is increased, and the number of connection points is increased, thereby improving the stability of the atomizer cover 20 after assembly. In other atomizer covers 20, the third limiting cylinder 231 is abutted against the first limiting cylinder 24, and the second limiting cylinder 25 is engaged with the card slot 236, which are all within the protection scope of this application.

[0085] Embodiment 3

[0086] like Figures 7 to 10As shown, the atomizing cover 20 also includes a first cover body 22, an atomizing core 224, and a support seat 28. The support seat 28 is installed in the first cover body 22. The outer wall of the support seat 28 is sealed and connected to the inner wall of the first cover body 22. The support seat 28 separates the inner cavity of the first cover body 22 to form a first atomizing cavity 202 and a cavity 242; the atomizing core 224 is installed on the support seat 28, and the atomizing core 224 has an atomizing position 2240 and a liquid inlet 2243. The support seat 28 has a liquid inlet channel 284. The atomizing position 2240 is arranged in the first atomizing cavity 202, and the atomizing position 2240 is connected to the first end of the liquid inlet channel 284 through the liquid inlet 2243. The second end of the liquid inlet channel 284 is arranged in the cavity 242, and the second end of the liquid inlet channel 284 is used to install the straw 221.

[0087] Specifically, after the support seat 28 separates the first cover body 22, the atomizer core 224 is installed on the support seat 28. The support seat 28 is provided with a liquid inlet channel 284. The liquid inlet port 2243 of the atomizer core 224 is connected to the first end of the liquid inlet channel 284. The second end of the liquid inlet channel 284 is set in the cavity 242. When the atomizer cover 20 and the atomizer bottle 21 are assembled, the cavity 242 is connected to the liquid containing cavity 204. When the second end of the liquid inlet channel 284 is installed with the suction tube 221, the atomizer core 224 will absorb the essential oil in the liquid containing cavity 204 through the liquid inlet channel 284 and the suction tube 221, and transport the essential oil to the atomization position 2240, so that it is blown away by the high-pressure gas of the atomization position 2240. After the essential oil is blown away, a particle spray is formed. Since the support seat 28 separates the inner cavity of the first cover body 22, the atomization position 2240 is set in the first atomization chamber 202, and when the atomization core 224 is in operation, the essential oil in the liquid chamber 204 is absorbed into the atomization position 2240, and the particle spray naturally cannot enter the liquid inlet 2243 and the liquid inlet channel 284 from the atomization position 2240. Therefore, the particle spray can only diffuse in the first atomization chamber 202, which can prevent the particle spray from entering the liquid chamber 204 and contacting the essential oil, and avoiding being adsorbed by the essential oil. The particle spray in the first atomization chamber 202 will be discharged from the spray port 201 of the atomization cover 20, thereby improving the problem of small flow rate of the spray port 201 of the existing atomizer 2.

[0088] In some embodiments, Fig.10 , Fig.13 , Fig.14As shown, the atomization core 224 has an air inlet 2244, an air outlet 2242, and a liquid outlet 2241. The air inlet 2244 is connected to the air outlet 2242, and the liquid inlet 2243 is connected to the liquid outlet 2241. The air outlet 2242 and the liquid outlet 2241 are both arranged in the first atomization chamber 202, and the air outlet 2242 is arranged close to the liquid outlet 2241; an atomization position 2240 is formed between the air outlet 2242 and the liquid outlet 2241, and the air outlet direction of the air outlet 2242 intersects with the liquid outlet direction of the liquid outlet 2241. Specifically, the air inlet 2244 of the atomizing core 224 is connected to the air inlet end 209 of the first cover body 22, the first end of the airway hose 41 is connected to the air pump 4, and the second end of the airway hose 41 is installed on the air inlet end 209. The high-pressure gas flows out from the air inlet 2244 and the air outlet 2242 in sequence. The high-pressure gas at the air outlet 2242 blows away the essential oil at the liquid outlet 2241, so that the atomizing position 2240 produces more particle spray. Under the action of the high-pressure gas, a pressure difference is generated between the liquid outlet 2241 and the liquid inlet 2243, so that the essential oil at the liquid inlet 2243 is continuously transported to the liquid outlet 2241. Moreover, Fig.13 It can be seen that the air outlet direction of the air outlet 2242 intersects with the liquid outlet direction of the liquid outlet 2241, the liquid outlet direction is horizontal, and the air outlet direction is vertical. The essential oil from the liquid outlet 2241 drops on the top of the air outlet 2242, and the high-pressure gas from the air outlet 2242 directly blows away the dripping essential oil droplets, so that the essential oil forms a particle spray.

[0089] In some embodiments, Fig.13 and Fig.14As shown, the atomizer core 224 includes a first seat body 2245, a second seat body 2246, and a third seat body 2247. The third seat body 2247 is installed on the first end of the second seat body 2246, and the second end of the second seat body 2246 is installed on the first seat body 2245; the liquid inlet 2243 and the air inlet 2244 are both opened at the bottom of the first seat body 2245, and the air outlet 2242 and the liquid outlet 2241 are both opened at the side wall of the third seat body 2247; an L-shaped groove 2248 is formed between the outer wall of the first seat body 2245 and the bottom of the second seat body 2246. Specifically, the air inlet 2244 and the liquid inlet 2243 are provided on the first seat body 2245, and the support seat 28 is provided with an air inlet end 209, the air inlet direction of the air inlet end 209 intersects with the direction of the air inlet 2244, and the liquid outlet direction of the liquid outlet 2241 is downward, which is used to correspond to the liquid inlet channel 284; the third seat body 2247 is provided to make the support seat 28 protrude upward, which is used to raise the height of the atomization position 2240 in the first atomization chamber 202, and it is also convenient to set the air outlet direction of the air outlet 2242 to be horizontal. The second end of the second seat body 2246 is installed on the first seat body 2245, so that there is an L-shaped groove 2248 between the second seat body 2246 and the first seat body 2245, and this L-shaped groove 2248 is used to be clamped on the support seat 28, so that the second seat body 2246 and the support seat 28 are against each other, and the stability of the atomization core 224 on the support seat 28 is improved.

[0090] In order to improve the sealing between the support base 28 and the first cover body 22. In some embodiments, Fig. 9 As shown, the first cover body 22 includes a first limiting column 24, a second limiting column 25, and at least one sealing rubber ring 225. The first limiting column 24 is sleeved on the outside of the second limiting column 25, and the first end of the first limiting column 24 is fixed to the first end of the second limiting column 25, and the second end of the first limiting column 24 and the second end of the second limiting column 25 are spaced apart; the second limiting column 25 is sleeved on the outside of the support seat 28, the sealing rubber ring 225 is arranged between the second limiting column 25 and the support seat 28, and the second limiting column 25 is sealed and connected to the support seat 28 through the sealing rubber ring 225. Specifically, the inner wall of the second limiting cylinder 25 is flexibly connected to the outer wall of the support seat 28 through the sealing rubber ring 225, so as to avoid the support seat 28 from squeezing and damaging the first cover 22 when the support seat 28 is installed. Moreover, by providing the sealing rubber ring 225, the sealing between the support seat 28 and the first cover 22 can be improved, so that the particle spray of the first atomization chamber 202 cannot enter the cavity 242. Preferably, the first limiting cylinder 24 and the second limiting cylinder 25 are an integrated structure, and the bottom of the first limiting cylinder 24 and the bottom of the second limiting cylinder 25 are integrally die-casted to improve the stability of the first cover 22, and then the first limiting cylinder 24 and the second limiting cylinder 25 are assembled with the second cover 23 at the top.

[0091] In order to improve the stability of the sealing rubber ring 225 between the support seat 28 and the second limiting column 25, preferably, as Fig. 9 As shown, the outer wall of the support seat 28 has at least one groove 282, and the groove 282 is extended along the outer wall of the support seat 28. The sealing rubber ring 225 is at least partially disposed in the groove 282, and the sealing rubber ring 225 is respectively against the outer wall of the support seat 28 and the inner wall of the second limiting column 25. The outer wall of the support seat 28 has the condition of opening the groove 282, and at least a part of the sealing rubber ring 225 is disposed in the groove 282, so as to limit the position of the sealing rubber ring 225 on the outer wall of the support seat 28, and improve the stability of the sealing rubber ring 225 between the support seat 28 and the second limiting column 25.

[0092] Optionally, a semicircular groove 282 is opened on the inner wall of the second limiting column 25 and the outer wall of the support seat 28. When the support seat 28 is assembled with the first cover body 22, the sealing rubber ring 225 is respectively arranged in the groove 282 of the second limiting column 25 and the support seat 28. In this way, the depth of the groove 282 opened on the outer wall of the support seat 28 can be reduced, thereby further improving the processing flexibility of the support seat 28 and the first cover body 22.

[0093] Preferably, there are two grooves 282, which are distributed in the height direction of the support seat 28, and the number of the sealing rubber rings 225 corresponds to the number of the grooves 282. Specifically, when multi-stage sealing is required, two sealing rubber rings 225 need to be configured, and the two sealing rubber rings 225 are respectively arranged in the two grooves 282, so as to further improve the sealing between the support seat 28 and the first cover body 22, and prevent the particle spray of the first atomization chamber 202 from overflowing into the liquid containing chamber 204 or the cavity 242.

[0094] In order to avoid the waste of essential oil. Preferably, Fig. 9 and Fig.10As shown, the atomizing cover 20 also includes a second cover body 23, a top plate 29 is provided in the first cover body 22, the top plate 29 is provided with a through hole, the second cover body 23 is provided with a spray port 201, the second cover body 23 is installed on the first cover body 22, and a second atomizing chamber 203 is formed between the second cover body 23 and the top plate 29, the spray port 201 is connected with the second atomizing chamber 203, and the second atomizing chamber 203 is connected with the first atomizing chamber 202 through the through hole. Specifically, the atomizing position 2240 is used to blow away the essential oil and form a particle spray that gathers in the first atomizing chamber 202; if the larger particle spray flows out of the spray port 201, it cannot achieve the effect of spreading the fragrance because of the limited diffusion distance of its own weight; therefore, when the larger particle spray moves in the first atomizing chamber 202, it is also easy to adhere to the second limiting column 25 and the top plate 29 due to its own weight, so as to prevent the larger particle spray from flowing from the through hole to the second atomizing chamber 203. It can be seen that the top plate 29 is provided to separate the inner cavity of the atomizing cover 20 to form the first atomizing cavity 202 and the second atomizing cavity 203, so as to avoid the waste of essential oil.

[0095] This embodiment also provides an atomizer 2, such as Figures 4 to 6 As shown, it includes an atomizer bottle 21, a straw 221, and the atomizer cover 20 as mentioned above. A liquid containing cavity 204 is formed in the atomizer bottle 21. The first cover body 22 of the atomizer cover 20 is threadedly connected to the atomizer bottle 21. The liquid containing cavity 204 is communicated with the cavity 242. The first end of the straw 221 is installed on the second end of the liquid inlet channel 284, and the second end of the straw 221 is arranged at the bottom of the atomizer bottle 21. Specifically, when the atomizing cover 20 is assembled with the atomizing bottle 21, the cavity 242 of the atomizing cover 20 is a part of the liquid containing cavity 204, and the liquid containing cavity 204 is used to contain essential oil. The straw 221 is installed at the second end (bottom end) of the liquid inlet channel 284. When the air pump 4 delivers high-pressure gas toward the gas outlet 2242, the liquid outlet 2241 is in a negative pressure state. Since the liquid outlet 2241, the liquid inlet 2243, the liquid inlet channel 284, and the straw 221 are connected in sequence, there is an air pressure difference between the bottom of the straw 221 and the liquid outlet 2241; therefore, the essential oil at the bottom of the atomizing bottle 21 will be continuously delivered to the liquid outlet 2241 by the straw 221, and continuous atomization operation is achieved. When the air pump 4 stops working, the pressure difference between the air pressure of the liquid outlet 2241 and the bottom of the straw 221 disappears, and the essential oil cannot be delivered to the liquid outlet 2241.

[0096] This embodiment also provides a fragrance diffuser 100, such as Figures 1 to 3As shown, it includes a housing 1, an air pump 4, a plug assembly 3, and the above-mentioned atomizer 2. The housing 1 has an installation cavity, the air pump 4 and the atomizer 2 are both installed in the installation cavity, and the atomizer 2 is at least partially exposed relative to the housing 1. The plug assembly 3 is installed on the side wall of the housing 1, the plug assembly 3 is electrically connected to the air pump 4, and the air outlet end of the air pump 4 is connected to the air inlet 2244 of the atomizer core 224. Specifically, by installing the plug assembly 3 on the side wall of the housing 1, when the aroma diffuser 100 is in use, the aroma diffuser 100 is plugged into the socket, the air pump 4 is connected to the power supply through the plug assembly 3, the air pump 4 is turned on after being conductive, and continuously delivers high-pressure gas to the atomizer cover 20.

[0097] In this embodiment, the aroma diffuser 100 also has a support plate 26, a circuit board 27, an operating component 102, and an inner shell 13. The inner shell 13 is used to accommodate the atomizer 2. The inner shell 13 is arranged in the outer shell 1. The outer wall of the inner shell 13 is used to install the support plate 26 and the circuit board 27. The support plate 26 is used to fix or support the circuit board 27. The operating component 102 is installed on the outer surface of the outer shell 1. The operating component 102 has a plurality of operating buttons, and the plurality of operating buttons are electrically connected to the circuit board 27. The plurality of operating buttons are used to control the atomizer 2 through the circuit board 27.
