Description

Technical Field

[0001] This utility model relates to the technical field of fragrance diffusers, and in particular to an atomizing cap, an atomizer, and a fragrance diffuser. Background Technology

[0002] Atomizers generally include an atomizing cap, an atomizing coil, and an atomizing bottle. The atomizing cap is installed on the atomizing bottle, and the atomizing coil is installed on the atomizing cap. An atomizing chamber is formed inside the atomizing cap, and a liquid-containing chamber is formed inside the atomizing bottle. The atomizing chamber is generally connected to the liquid-containing chamber. The atomizing coil has an atomizing position, which is located inside the atomizing chamber.

[0003] However, in the operation of atomizing essential oils, the essential oils are blown apart by high-pressure gas to form particulate spray. The particulate spray diffuses in the atomizing chamber, and part of it flows out through the spray nozzle of the atomizing cap. Another part of the particulate spray comes into contact with the essential oil in the liquid chamber. The essential oil has adsorption properties, and another part of the particulate spray is adsorbed by the essential oil, resulting in a smaller flow rate at the spray nozzle. Summary of the Invention

[0004] The purpose of this invention is to improve the problem of low spray flow in existing atomizers and to provide an atomizing cap, atomizer, and fragrance diffuser.

[0005] The technical solutions for achieving the above objectives include the following:

[0006] The atomizing cap includes: a first cap body, an atomizing core, and a support base. The support base is installed inside the first cap body, and the outer wall of the support base is sealed to the inner wall of the first cap body. The support base separates the inner cavity of the first cap body and forms a first atomizing cavity and an empty cavity.

[0007] The atomizing core is mounted on a support base. The atomizing core has an atomizing position and a liquid inlet. The support base has a liquid inlet channel. The atomizing position is located in a first atomizing chamber. The atomizing position is connected to the first end of the liquid inlet channel through the liquid inlet. The second end of the liquid inlet channel is located in a cavity. The second end of the liquid inlet channel is used to install a straw.

[0008] In one embodiment, the atomizing core has an air inlet, an air outlet, and a liquid outlet. The air inlet and the air outlet are connected, and the liquid inlet and the liquid outlet are connected. Both the air outlet and the liquid outlet are located in the first atomizing chamber, and the air outlet is located close to the liquid outlet.

[0009] The atomization position is formed between the air outlet and the liquid outlet, and the air outlet direction intersects the liquid outlet direction.

[0010] In one embodiment, the atomizing core includes a first base, a second base, and a third base. The third base is mounted on the first end of the second base, and the second end of the second base is mounted on the first base. The liquid inlet and the air inlet are both located at the bottom of the first base, and the air outlet and the liquid outlet are both located on the side wall of the third base.

[0011] An L-shaped groove is formed between the outer wall of the first seat and the bottom of the second seat.

[0012] In one embodiment, the first cover includes a first limiting post, a second limiting post, and at least one sealing ring. The first limiting post is sleeved on the outside of the second limiting post, and the first end of the first limiting post is fixed to the first end of the second limiting post. The second end of the first limiting post and the second end of the second limiting post are spaced apart.

[0013] The second limiting post is sleeved on the outside of the support base, and the sealing ring is disposed between the second limiting post and the support base, and the second limiting post is sealed to the support base through the sealing ring.

[0014] In one embodiment, the outer wall of the support base has at least one groove extending along the outer wall of the support base, and the sealing ring is at least partially disposed in the groove, and the sealing ring abuts against the outer wall of the support base and the inner wall of the second limiting column.

[0015] In one embodiment, the groove has two grooves, which are distributed along the height direction of the support, and the number of sealing rings corresponds to the number of grooves.

[0016] In one embodiment, the atomizing cover further includes a second cover body, the first cover body has a top plate with a through hole, the second cover body has a spray nozzle, the second cover body is installed on the first cover body, and a second atomizing cavity is formed between the second cover body and the top plate, the spray nozzle communicates with the second atomizing cavity, and the second atomizing cavity communicates with the first atomizing cavity through the through hole.

[0017] In one embodiment, the second cover includes a cover plate and a third limiting post. The third limiting post is installed under the cover plate, and the cover plate has a slot. The third limiting post is sleeved on the outside of the first limiting post, and the inner wall of the third limiting post abuts against the outer wall of the first limiting post. The second limiting post is engaged with the slot.

[0018] This utility model also proposes an atomizer, including an atomizing bottle, a straw, and an atomizing cap as described above. A liquid-containing cavity is formed inside the atomizing bottle. The first cap of the atomizing cap is threadedly connected to the atomizing bottle. The liquid-containing cavity is in communication with the cavity. The first end of the straw is installed at the second end of the liquid inlet channel, and the second end of the straw is located at the bottom of the atomizing bottle.

[0019] This utility model also proposes a fragrance diffuser, characterized in that it includes a housing, an air pump, a plug assembly, and an atomizer as described above.

The plug assembly is installed on the side wall of the housing and is electrically connected to the air pump. The air outlet of the air pump is connected to the air inlet of the atomizer core.

[0020] The technical solution provided by this utility model has the following advantages and effects:

[0021] Because the support base separates the inner cavity of the first cover, the atomizing position is located in the first atomizing chamber. When the atomizing core is in operation, the essential oil in the liquid chamber is drawn into the atomizing position. The particulate spray cannot enter the liquid inlet and the liquid inlet channel from the atomizing position. Therefore, the particulate spray can only diffuse in the first atomizing chamber. This can prevent the particulate spray from entering the liquid chamber and coming into contact with the essential oil, and avoid being absorbed by the essential oil. The particulate spray in the first atomizing chamber will be discharged from the spray port of the atomizing cover, which improves the problem of the small spray flow of the existing atomizer.

[0052] Example 1

[0053] like Figures 7 to 10 As shown, the atomizing cover 20 includes a first cover body 22, an atomizing core 224, and a support base 28. The support base 28 is installed inside the first cover body 22, and the outer wall of the support base 28 is sealed to the inner wall of the first cover body 22. The support base 28 separates the inner cavity of the first cover body 22 to form a first atomizing chamber 202 and a cavity 242. The atomizing core 224 is installed on the support base 28. The atomizing core 224 has an atomizing position 2240 and a liquid inlet 2243. The support base 28 has a liquid inlet channel 284. The atomizing position 2240 is located in the first atomizing chamber 202. 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 located in the cavity 242. The second end of the liquid inlet channel 284 is used to install a straw 221.

[0054] Specifically, after the support base 28 separates the first cover 22, the atomizing core 224 is installed on the support base 28. The support base 28 is provided with a liquid inlet channel 284. The liquid inlet 2243 of the atomizing core 224 is connected to the first end of the liquid inlet channel 284. The second end of the liquid inlet channel 284 is located in the cavity 242. When the atomizing cover 20 and the atomizing bottle 21 are assembled, the cavity 242 is connected to the liquid-containing cavity 204. When the straw 221 is installed at the second end of the liquid inlet channel 284, the atomizing core 224 will draw the essential oil from the liquid-containing cavity 204 through the liquid inlet channel 284 and the straw 221, and deliver the essential oil to the atomizing position 2240, where it will be dispersed by the high-pressure gas of the atomizing position 2240. After the essential oil is dispersed, it forms a particulate spray. Since the support base 28 separates the inner cavity of the first cover 22, the atomizing position 2240 is located in the first atomizing chamber 202. When the atomizing core 224 is in operation, the essential oil in the liquid chamber 204 is drawn into the atomizing position 2240. The particulate spray cannot enter the liquid inlet 2243 and the liquid inlet channel 284 from the atomizing position 2240. Therefore, the particulate spray can only diffuse in the first atomizing chamber 202. This can prevent the particulate spray from entering the liquid chamber 204 and coming into contact with the essential oil, and avoid being absorbed by the essential oil. The particulate spray in the first atomizing chamber 202 will be discharged from the spray port 201 of the atomizing cover 20, which improves the problem of the small flow rate of the spray port 201 of the existing atomizer 2.

[0055] In some embodiments, such as Figure 10 , Figure 13 , Figure 14As shown, the atomizing 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. Both the air outlet 2242 and the liquid outlet 2241 are located in the first atomizing chamber 202, with the air outlet 2242 located close to the liquid outlet 2241. An atomizing 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 209 of the first cover 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 209. High-pressure gas flows out sequentially from the air inlet 2244 and the air outlet 2242. The high-pressure gas at the air outlet 2242 disperses the essential oil at the liquid outlet 2241, causing the atomizing position 2240 to produce a large amount of particulate spray. Under the action of the high-pressure gas, a pressure difference is generated between the liquid outlet 2241 and the liquid inlet 2243, thereby continuously supplying the essential oil from the liquid inlet 2243 to the liquid outlet 2241. Moreover, from Figure 13 As can be seen, the air outlet 2242's air outlet direction intersects with the liquid outlet 2241's liquid outlet direction. The liquid outlet direction is horizontal, and the air outlet direction is vertical. The essential oil droplets from the liquid outlet 2241 fall above the air outlet 2242. The high-pressure gas from the air outlet 2242 directly blows away the falling essential oil droplets, causing the essential oil to form a particulate spray.

[0056] In some embodiments, such as Figure 13 and Figure 14As shown, the atomizing core 224 includes a first base 2245, a second base 2246, and a third base 2247. The third base 2247 is installed on the first end of the second base 2246, and the second end of the second base 2246 is installed on the first base 2245. The liquid inlet 2243 and the air inlet 2244 are both located at the bottom of the first base 2245, and the air outlet 2242 and the liquid outlet 2241 are both located on the side wall of the third base 2247. An L-shaped groove 2248 is formed between the outer wall of the first base 2245 and the bottom of the second base 2246. Specifically, an air inlet 2244 and a liquid inlet 2243 are provided on the first seat 2245. A support 28 is provided with an air inlet end 209, the air inlet direction of which intersects with the direction of the air inlet 2244. The liquid outlet 2241 faces downwards, corresponding to the liquid inlet channel 284. A third seat 2247 is provided to make the support 28 protrude upwards, raising the height of the atomizing position 2240 in the first atomizing chamber 202, and also facilitating setting the air outlet 2242's outlet direction to be horizontal. The second end of a second seat 2246 is installed on the first seat 2245, creating an L-shaped groove 2248 between the second seat 2246 and the first seat 2245. This L-shaped groove 2248 is used to engage with the support 28, causing the second seat 2246 to abut against the support 28, improving the stability of the atomizing core 224 on the support 28.

[0057] To improve the sealing between the support 28 and the first cover 22. In some embodiments, such as Figure 9 As shown, the first cover 22 includes a first limiting post 24, a second limiting post 25, and at least one sealing ring 225. The first limiting post 24 is sleeved on the outside of the second limiting post 25, and the first end of the first limiting post 24 is fixed to the first end of the second limiting post 25. The second end of the first limiting post 24 and the second end of the second limiting post 25 are spaced apart. The second limiting post 25 is sleeved on the outside of the support base 28. The sealing ring 225 is disposed between the second limiting post 25 and the support base 28, and the second limiting post 25 is sealed to the support base 28 through the sealing ring 225. Specifically, the inner wall of the second limiting post 25 is flexibly connected to the outer wall of the support base 28 via a sealing ring 225, preventing the support base 28 from squeezing and damaging the first cover 22 during installation. Furthermore, the sealing ring 225 improves the seal between the support base 28 and the first cover 22, preventing the particle spray from the first atomizing chamber 202 from entering the cavity 242. Preferably, the first limiting post 24 and the second limiting post 25 are an integral structure, with the bottom of the first limiting post 24 and the bottom of the second limiting post 25 integrally die-cast to improve the stability of the first cover 22. Then, the tops of the first limiting post 24 and the second limiting post 25 are used to assemble with the second cover 23.

[0058] To improve the stability of the sealing ring 225 between the support base 28 and the second limiting post 25, preferably, as follows: Figure 9 As shown, the outer wall of the support base 28 has at least one groove 282, which extends along the outer wall of the support base 28. A sealing ring 225 is at least partially disposed within the groove 282, and the sealing ring 225 abuts against the outer wall of the support base 28 and the inner wall of the second limiting post 25. The outer wall of the support base 28 has the conditions to form the groove 282, and by placing at least a portion of the sealing ring 225 within the groove 282, the position of the sealing ring 225 on the outer wall of the support base 28 is restricted, thereby improving the stability of the sealing ring 225 between the support base 28 and the second limiting post 25.

[0059] Optionally, semi-circular grooves 282 are formed on the inner wall of the second limiting post 25 and the outer wall of the support seat 28. After the support seat 28 is assembled with the first cover 22, the sealing rings 225 are respectively set in the grooves 282 of the second limiting post 25 and the support seat 28. This can reduce the depth of the grooves 282 formed on the outer wall of the support seat 28 and further improve the processing flexibility of the support seat 28 and the first cover 22.

[0060] Preferably, there are two grooves 282, which are distributed along the height of the support 28. The number of sealing rings 225 corresponds to the number of grooves 282. Specifically, when multi-stage sealing is required, two sealing rings 225 are provided, each disposed in one of the two grooves 282. This further improves the sealing between the support 28 and the first cover 22, preventing the particle spray from the first atomizing chamber 202 from overflowing into the liquid chamber 204 or the cavity 242.

[0061] To avoid wasting essential oils, the preferred choice is, for example... Figure 9 and Figure 10As shown, the atomizing cover 20 also includes a second cover 23. The first cover 22 has a top plate 29 with a through hole. The second cover 23 has a spray nozzle 201. The second cover 23 is installed on the first cover 22, and a second atomizing chamber 203 is formed between the second cover 23 and the top plate 29. The spray nozzle 201 communicates with the second atomizing chamber 203, and the second atomizing chamber 203 communicates with the first atomizing chamber 202 through the through hole. Specifically, the atomizing position 2240 is used to disperse the essential oil and form a particulate spray that gathers in the first atomizing chamber 202. If a larger particulate spray flows out of the spray nozzle 201, its diffusion distance is limited due to its own weight, and it cannot achieve the aroma diffusion effect. Therefore, when the larger particulate spray moves in the first atomizing chamber 202, it is also easy to adhere to the second limiting post 25 and the top plate 29 due to its own weight, preventing the larger particulate spray from flowing from the through hole to the second atomizing chamber 203. As can be seen, by setting the top plate 29 to separate the inner cavity of the atomizing cover 20 to form the first atomizing chamber 202 and the second atomizing chamber 203, the waste of essential oil can be avoided.

[0062] This embodiment also proposes an atomizer 2, such as Figures 4 to 6 As shown, the atomizing bottle 21, straw 221, and atomizing cap 20 as described above are included. A liquid-containing cavity 204 is formed inside the atomizing bottle 21. The first cap 22 of the atomizing cap 20 is threadedly connected to the atomizing bottle 21. The liquid-containing cavity 204 is connected to the cavity 242. The first end of the straw 221 is installed at the second end of the liquid inlet channel 284, and the second end of the straw 221 is located at the bottom of the atomizing bottle 21. Specifically, after the atomizing cap 20 and the atomizing bottle 21 are assembled, the cavity 242 of the atomizing cap 20 becomes part of the liquid-containing chamber 204, which 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 air outlet 2242, the liquid outlet 2241 is under negative pressure. Since the liquid outlet 2241, the liquid inlet 2243, the liquid inlet channel 284, and the straw 221 are connected in sequence, there is a 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, achieving continuous atomization. When the air pump 4 stops operating, the pressure difference between the air outlet 2241 and the bottom of the straw 221 disappears, and the essential oil cannot be delivered to the liquid outlet 2241.

[0063] This embodiment also proposes a fragrance diffuser 100, such as Figures 1 to 3As shown, the device includes a housing 1, an air pump 4, a plug assembly 3, and an atomizer 2 as described above. The housing 1 has a mounting cavity, in which both the air pump 4 and the atomizer 2 are installed, with at least a portion of the atomizer 2 exposed relative to the housing 1. The plug assembly 3 is installed on the side wall of the housing 1 and is electrically connected to the air pump 4. The air outlet of the air pump 4 is connected to the air inlet 2244 of the atomizing core 224. Specifically, by installing the plug assembly 3 on the side wall of the housing 1, when the fragrance diffuser 100 is in use, it is plugged into a socket, and the air pump 4 is connected to the power supply through the plug assembly 3. After the air pump 4 is powered, it turns on and continuously delivers high-pressure gas into the atomizing cover 20.

[0064] In this embodiment, the aroma diffuser 100 also includes 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 and is disposed inside 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 and has multiple operating buttons. The multiple operating buttons are electrically connected to the circuit board 27 and are used to control the atomizer 2 through the circuit board 27.

[0065] Example 2

[0066] This utility model also proposes an atomizing cap 20, such as Figures 7 to 11 As shown, it includes: a first cover 22 and a second cover 23. The first cover 22 includes a first limiting post 24 and a second limiting post 25. The first limiting post 24 is sleeved on the outside of the second limiting post 25, and the first end of the first limiting post 24 is fixed to the first end of the second limiting post 25. The second end of the first limiting post 24 and the second end of the second limiting post 25 are spaced apart. The second cover 23 includes a third limiting post 231 and a cover plate 232. The third limiting post 231 is installed under the cover plate 232, and the cover plate 232 has a slot 236. The third limiting post 231 is sleeved on the outside of the first limiting post 24, and the inner wall of the third limiting post 231 abuts against the outer wall of the first limiting post 24. The second limiting post 25 is engaged with the slot 236.

[0067] Specifically, the first cover 22 and the second cover 23 are assembled by a snap-fit ​​method. The slot 236 positions the first cover 22 for installation. When the second limiting post 25 corresponds to the slot 236, the third limiting post 231 can be sleeved on the outside of the first limiting post 24, or the first limiting post 24 can be sleeved on the outside of the third limiting post 231, thereby improving the efficiency of the first cover 22 and the second cover 23 during assembly. Furthermore, when the second limiting post 25 is at least partially inserted into the slot 236 and engages with the slot 236, the inner / outer wall of the third limiting post 231 abuts against the outer / inner wall of the first limiting post 24, increasing the connection area between the first cover 22 and the second cover 23. Simultaneously, after the third limiting post 231 abuts against the first limiting post 24, the third limiting post 231 squeezes the first limiting post 24, and the first limiting post 24 generates a reaction force acting on the third limiting post 231, increasing the frictional resistance between the first cover 22 and the second cover 23, and improving the stability of the first cover 22 and the second cover 23 after assembly.

[0068] Furthermore, the third limiting post 231 and the first limiting post 24 form the first connection position after the atomizing cover 20 is assembled, and the second limiting post 25 and the slot 236 of the cover plate 232 form the second connection position after the atomizing cover 20 is assembled. By setting two connection positions, and with the first limiting post 24 sleeved on the second limiting post 25, and the first cover 22 fixed to the second cover 23 through the first limiting post 24 and the second limiting post 25, the atomizing cover 20 has different connection positions in the radial direction, further improving the stability of the atomizing cover 20 after assembly.

[0069] In some embodiments, such as Figure 11 and Figure 12As shown, the second cover 23 also includes a fourth limiting post 233 and a fifth limiting post 234. The outer diameter of the fifth limiting post 234 is larger than the outer diameter of the fourth limiting post 233. Both the fourth limiting post 233 and the fifth limiting post 234 are installed at the lower end of the cover plate 232. The fourth limiting post 233 is disposed inside the fifth limiting post 234. The fourth limiting post 233 and the fifth limiting post 234 are arranged in concentric circles, and a groove 236 is formed between the outer wall of the fourth limiting post 233 and the inner wall of the fifth limiting post 234. Specifically, since the fourth limiting post 233 and the fifth limiting post 234 are arranged in concentric circles, and the fourth limiting post 233 is located inside the fifth limiting post 234, the slot 236 can be extended along the circumference of the fourth limiting post 233, and the width of the slot 236 remains consistent. When the second limiting post 25 engages with the slot 236, the inner wall of the second limiting post 25 abuts against the outer wall of the fourth limiting post 233, and the outer wall of the second limiting post 25 abuts against the inner wall of the fifth limiting post 234, increasing the connection area between the first cover 22 and the second cover 23 after assembly, thereby further improving the stability of the atomizing cover 20 after assembly.

[0070] In some embodiments, such as Figure 11 and Figure 12 As shown, the height of the fourth limiting post 233 is greater than the height of the fifth limiting post 234, and the bottom of the fourth limiting post 233 is lower than the bottom of the fifth limiting post 234; the outer wall of the fourth limiting post 233 is used to abut against the inner wall of the second limiting post 25. Specifically, by increasing the height of the fourth limiting post 233, the connection area between the second limiting post 25 and the fourth limiting post 233 is increased. When the second limiting post 25 presses against the outer wall of the fourth limiting post 233 and the inner wall of the fifth limiting post 234 respectively, a larger frictional resistance will be generated between the second limiting post 25 and the fourth limiting post 233, further improving the stability of the atomizing cover 20 after assembly.

[0071] In some embodiments, such as Figure 11 and Figure 12As shown, the outer wall of the first limiting post 24 has a first protrusion 241, which extends circumferentially along the first limiting post 24; the outer wall of the fourth limiting post 233 has a second protrusion 235, which extends circumferentially along the fourth limiting post 233; the third limiting post 231 is provided with a first limiting groove that mates with the first protrusion 241, and the second limiting post 25 is provided with a second limiting groove that mates with the second protrusion 235. Specifically, by using the first protrusion 241 to mate with the first limiting groove and the second protrusion 235 to mate with the second limiting groove, the vertical movement resistance between the first limiting post 24 and the third limiting post 231, and between the second limiting post 25 and the fourth limiting post 233, is increased, thus achieving the setting of limiting structures at two different connection positions of the first cover 22 and the second cover 23. Furthermore, the number of second protrusions 235 can be set to two, with the two second protrusions 235 arranged along the height direction of the fourth limiting post 233, further improving the connection stability between the second limiting post 25 and the fourth limiting post 233.

[0072] Preferred, such as Figure 11 As shown, the first limiting post 24 includes a supporting portion 243 and an abutting portion 244. The abutting portion 244 is installed on the supporting portion 243, and 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 post 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, it increases the supporting strength of the first limiting post 24, preventing the first limiting post 24 from being squeezed by the third limiting post 231 and causing the first limiting post 24 to break or deform. Moreover, the abutting portion 244 is used to abut against the inner wall of the third limiting post 231, playing the role of supporting and fixing the third limiting post 231.

[0073] In some embodiments, such as Figure 10As shown, the atomizing cover 20 also has a support base 28 and an atomizing core 224. The support base 28 is installed inside the second limiting post 25, and the atomizing core 224 is installed on the support base 28. The atomizing core 224 has an atomizing position 2240. The first cover 22 also has a top plate 29, which is installed inside the second limiting post 25. The lower end of the top plate 29 and the support base 28 form a first atomizing cavity 202, and the atomizing position 2240 is disposed inside the first atomizing cavity 202. Specifically, the bottom of the second limiting column 25 is used to support or fix the support base 28, and the support base 28 is used to install the atomizing core 224, so that the atomizing position 2240 of the atomizing core 224 is set in the first atomizing chamber 202. The first atomizing chamber 202 is separated from the cavity 242 of the first cover 22. Since the cavity 242 is the liquid-containing cavity 204 of the atomizing bottle 21 after the atomizing cover 20 is assembled with the atomizing bottle 21, the particulate spray in the first atomizing chamber 202 cannot come into contact with the essential oil in the liquid-containing cavity 204, thus avoiding the particulate spray being absorbed by the essential oil.

[0074] In some embodiments, such as Figure 10 As shown, the cover plate 232 has a spray nozzle 201. A second atomizing chamber 203 is formed between the lower end of the cover plate 232 and the upper end of the top plate 29. The top plate 29 has a through hole, through which the first atomizing chamber 202 communicates with the second atomizing chamber 203. The second atomizing chamber 203 communicates with the spray nozzle 201. Specifically, during the atomization of essential oil by the atomizing core 224, the high-pressure gas from the air pump 4 disperses the essential oil and forms particulate spray in the first atomizing chamber 202. The particulate spray from the first atomizing chamber 202 enters the second atomizing chamber 203 through the through hole. Since the diffusion distance of larger essential oil particles is limited, when larger particles in the first atomizing chamber 202 come into contact with the inner wall of the top plate 29 or the second limiting post 25, they are adsorbed by the walls of the top plate 29 and the second limiting post 25, preventing larger particles from flowing out of the spray nozzle 201 and avoiding waste of essential oil. The adsorbed particulate spray gathers to form a certain amount of liquid essential oil, which flows to the first vent 205 and then flows back to the liquid chamber 204 through the first vent 205.

[0075] This embodiment also proposes a fragrance diffuser 100, such as Figures 1 to 5As shown, the device includes a housing 1, an atomizing bottle 21, an air pump 4, and an atomizing cap 20 as described above. An installation cavity is formed within the housing 1. The atomizing cap 20 is mounted on the atomizing bottle 21. The atomizing bottle 21, the atomizing cap 20, and the air pump 4 are all installed within the installation cavity. The atomizing cap 20 is connected to the air pump 4, and at least a portion of the atomizing cap 20 is exposed relative to the housing 1. Specifically, the atomizing bottle 21 and the atomizing cap 20 are threaded together. The atomizing cap 20 has a straw 221. The first end of the straw 221 is fixed to the liquid inlet 2243 of the atomizing core 224, and the second end of the straw 221 is located at the bottom of the atomizing bottle 21. When the high-pressure gas from the air pump 4 is delivered to the air inlet 209 of the atomizing cap 20 through the airway hose 41 and enters the air inlet 2244 of the atomizing core 224, it flows out from the air outlet 2242. The high-pressure gas disperses the essential oil at the liquid outlet 2241. 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 this pressure difference, the straw 221 continuously delivers the essential oil from the liquid chamber 204 to the liquid outlet 2241, thereby achieving the purpose of atomizing the essential oil.

[0076] Furthermore, by placing the atomizing cap 20 and the atomizing bottle 21 inside the outer casing 1, most of the structure of the atomizer 2 is hidden inside the outer casing 1, while the atomizing cap 20 is at least partially exposed. When it is necessary to replace or add essential oil, the atomizing cap 20 can be held to remove the atomizing bottle 21 from the outer casing 1 for easy addition of essential oil.

[0077] In some embodiments, such as Figure 3 As shown, the outer casing 1 includes a first casing 11, a second casing 12, and a decorative panel 101. The first casing 11 is mounted on the second casing 12, and a mounting cavity is formed between the inner walls of the first casing 11 and the second casing 12. The decorative panel 101 is mounted on either the first casing 11 or the second casing 12, and at least part of the outer wall of the first casing 11 is covered by the decorative panel 101. Specifically, the decorative panel 101 is used to cover the outer surface of the first casing 11. When the fragrance diffuser 100 is fixed to the wall via the plug assembly 3 for atomization, the decorative panel 101 can improve the decorative effect of the outer surface of the fragrance diffuser 100. At the same time, depending on the material of the decorative panel 101, the tactile comfort of the fragrance diffuser 100 can be improved. In other embodiments, the decorative panel 101 can also cover a portion of the second casing 12, so that most of the outer surface area of ​​the fragrance diffuser 100 is covered or obscured by the decorative panel 101.

[0078] Preferred, such as Figures 1 to 3 , Figure 15 and Figure 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 baffle plate 1014, a first baffle strip 1015, and a second baffle strip 1016. The first baffle strip 1015 is installed at the first end of the baffle plate 1014, and the second baffle strip 1016 is installed at the second end of the baffle plate 1014. Both the first baffle strip 1015 and the second baffle strip 1016 are bent. A first guide groove 1017 is formed between the first baffle 1015 and the inner side of the baffle 1014, and a second guide groove 1018 is formed between the second baffle 1016 and the inner side of the baffle 1014. The two ends of the first panel 1011 are respectively disposed within the first guide grooves 1017 of the second panel 1012 and the third panel 1013. The first housing 11 or the second housing 12 has a third baffle 111, which is disposed within the second guide groove 1018. Specifically, by providing the first guide groove 1017 and the second guide groove 1018, after the first housing 11 and the second housing 12 are assembled, because the first housing 11 or the second housing 12 has the third baffle 111, the second panel 1012 and the third panel 1013 slide in cooperation with the third baffle 111 of the outer shell 1. The third baffle 111 slides into the second guide groove 1018, thus restricting the first ends of the second panel 1012 and the third panel 1013 by the third baffle 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. The first panel 1011 restricts 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 to the outer surface of the first housing 11. This installation method is relatively simple and stable, and there is no need to open screw holes in the first housing 11 and the second housing 12. That is to say, there are no screws on the decorative panel 101, which can increase the appearance of the decorative panel 101.

[0079] It should be noted that in this atomizing cover 20, the third limiting post 231 abuts against the first limiting post 24, and the second limiting post 25 engages with the slot 236; this achieves the snap-fit ​​assembly of the atomizing cover 20, and increases the connection area and connection points between the first cover 22 and the second cover 23, thereby improving the stability of the atomizing cover 20 after assembly. In other atomizing covers 20, the use of the third limiting post 231 abutting against the first limiting post 24 and the second limiting post 25 engaging with the slot 236 is also within the scope of protection of this application.

[0080] Example 3

[0081] This utility model also proposes an atomizer 2, such as Figures 3 to 6As shown, it includes: an atomizing bottle 21, an atomizing core 224, and an atomizing cap 20. The atomizing cap 20 is detachably installed on the atomizing bottle 21. A liquid-containing chamber 204 is formed inside the atomizing bottle 21. The atomizing cap 20 has a first atomizing chamber 202 inside. The atomizing core 224 is installed inside the atomizing cap 20. The atomizing core 224 has an atomizing position 2240 located in the first atomizing chamber 202. The atomizing core 224 has a liquid inlet 2243. The atomizing position 2240 communicates with the liquid-containing chamber 204 through the liquid inlet 2243. The atomizing cap 20 has an air hole. The first atomizing chamber 202 communicates with the liquid-containing chamber 204 through the air hole. The air hole is the only channel for the liquid-containing chamber 204 to communicate with the outside atmosphere. The diameter of the air hole has a first preset value. At the first preset value, the liquid in the liquid-containing chamber 204 cannot flow out from the air hole.

[0082] Specifically, the aperture of this pore has a first preset value, which limits the specific size of the pore. When the aperture of the pore decreases to a certain extent, the essential oil liquid has a certain surface tension when flowing into the pore, and a state in which liquid channels and gas channels coexist cannot be formed within the pore. When the atomizer 2 is tilted and not in operation, the liquid flowing into the pore will submerge the pore. 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 in which liquid channels and gas channels coexist cannot be formed within the pore. The pore cannot simultaneously supply liquid and gas flow, 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 is discharged from the liquid-containing chamber 204, a certain pressure difference is generated inside and outside the atomizer 2. Because of this pressure difference, the liquid cannot flow out continuously, thus achieving the purpose of preventing leakage.

[0083] When the atomizer 2 is continuously operating and tilted, the atomizing coil 224 needs to continuously draw essential oil from the liquid chamber 204, causing the air pressure in the liquid chamber 204 to be lower than the external air pressure. To balance the pressure difference between the inside and outside of the atomizer 2, the air vent will draw gas from the first atomizing chamber 202 into the liquid chamber 204, reducing the pressure difference between the inside and outside of the atomizer 2. Therefore, the essential oil in the liquid chamber 204 cannot leak through the air vent. This air vent design improves the problem of the relatively complex structure used to prevent essential oil leakage in existing atomizers 2.

[0084] Furthermore, if there are multiple pores, then the pore diameter of each pore also has a second preset value. Specifically, such as... Figure 6As shown, the vents include a first vent 205, a second vent 206, and a third vent 208. The liquid chamber 204 is connected to the first atomizing chamber 202 through the first vent 205. The atomizing cover 20 is provided with a return air channel 207 and a movable plug 226. The second vent 206 and the third vent 208 are respectively located at both ends of the return air channel 207. The first end of the return air channel 207 is connected to the solution chamber 204 through the second vent 206, and the second end of the return air channel 207 is connected to the first atomizing chamber 202 through the third vent 208. The movable plug 226 is movably disposed in the return air channel 207 and is positioned close to the third vent 208. The first vent 205 is used to communicate with the first atomizing chamber 202. The liquid-containing chamber 204 is connected to the return air channel 207 through the second vent 206, and the return air channel 207 is connected to the first atomizing chamber 202 through the third vent 208. Therefore, the liquid-containing chamber 204 is connected to the first atomizing chamber 202 through the first vent 205 and the third vent 208. When there are multiple vents, the first preset value is 0.2 mm to 0.8 mm, and the second preset value is less than 0.2 mm. Among the multiple vents, the diameter of the first vent 205 and the second vent 206 is smaller, and the liquid in the vent will generate a very large surface tension, so that the liquid cannot flow out continuously.

[0085] Furthermore, the return air channel 207 has a movable plug 226. When the atomizer 2 is not in operation and is tilted, the movable plug 226 will move to the vicinity of the third air hole 208 and block the third air hole 208. After the first air hole 205 is submerged in essential oil, the surface tension of the liquid in the first air hole 205 will prevent the essential oil from continuously flowing out of the first air hole 205. When the atomizer 2 is in operation and is tilted, as the liquid in the liquid chamber 204 is continuously delivered to the atomization position 2240, a pressure difference is generated inside and outside the liquid chamber 204. In order to balance this pressure difference, the air in the first atomization chamber 202 can enter the liquid chamber 204 through the first air hole 205, or the air in the first atomization chamber 202 can also enter the liquid chamber 204 through the third air hole 208, the return air channel 207, and the second air hole 206, increasing the efficiency of gas return. Because the gas has a certain pressure when it flows back to the third vent 208, this pressure may move the movable plug 226, allowing the gas to smoothly pass through the third vent 208 and enter the return gas channel 207.

[0086] Furthermore, by setting a second air hole 206 and a third air hole 208, and setting the movable plug 226 in the return air channel 207, the diameters of the second air hole 206 and the third air hole 208 are both less than 2 mm. When the liquid in the liquid chamber 204 flows back to the first atomizing chamber 202, the second air hole 206 and the third air hole 208 provide multiple obstructions to the liquid, further preventing the liquid from overflowing from the liquid chamber 204. At the same time, it also solves the problem of pressure difference generated inside and outside the atomizer 2 during operation.

[0087] Preferably, the inner diameter of the return air channel 207 is larger than the first preset value, the diameter of the third air hole 208 is larger than the first preset value, and the diameter 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 larger than the first preset value to facilitate the placement of the movable plug 226 in the return air channel 207; while the diameter of the third air hole 208 is larger than the first preset value to increase the flow rate of the return air in the third air hole 208, so that when the atomizer 2 is in operation, the air in the first atomizing chamber 202 can quickly return to the liquid chamber 204, and prevent the straw 221 from being unable to draw essential oil from the liquid chamber 204 due to pressure difference in the atomizing bottle 21.

[0088] In some embodiments, such as Figure 6 As shown, the atomizer 2 also includes a straw 221 and an air tube 222. The first end of the straw 221 is installed on the atomizing core 224, and the second end of the straw 221 is located at the bottom of the atomizing bottle 21. The air tube 222 is sleeved on the outside of the straw 221, and the first end of the air tube 222 is installed at the bottom of the atomizing cap 20. The first end of the air tube 222 is connected to the first air hole 205, and the second end of the air tube 222 is located at the bottom of the atomizing bottle 21. Specifically, since the first air hole 205 is connected to the air tube 222, the liquid levels inside and outside the air tube 222 are the same. When the atomizing core 224 draws essential oil from the liquid chamber 204 through the straw 221, the bottom of the straw 221 is at the bottom of the liquid chamber 204, and the liquid inside the air tube 222 is higher than the liquid outside the air tube 222. Since the first air hole 205 is connected to the air tube 222, air flows into the air tube 222 from the first air hole 205, thereby creating a siphon effect between the air tube 222 and the straw 221. The siphon effect causes the liquid inside the air tube 222 to flow quickly to the outside of the air tube 222, so that the liquid inside and outside the air tube 222 are at the same height, thus timely filling the liquid at the bottom of the liquid chamber 204.

[0089] In some embodiments, such as Figure 5 As shown, the bottom of the atomizer 2 also has a filter 223. The filter 223 is installed at the second end of the straw 221. The filter 223 is used to filter impurities in the essential oil, preventing impurities from moving to the atomizing core 224 with the essential oil and preventing impurities from clogging the atomizing core 224.
