Description

Technical Field

[0001] The embodiments of this utility model relate to an atomizing device, and more particularly to a core of an atomizing component and an atomizing component. Background Technology

[0002] Atomizing devices are electronic products that atomize liquids by heating them to produce a mist. They are widely used in many fields, such as the medical and home applications. Currently, some atomizing devices are also used in fragrance diffusers, which atomize volatile liquid media and then spray the atomized gas with an airflow to change the smell in the air and suppress odors.

[0003] Currently, atomizing devices used in fragrance diffusers generally consist of a heated base and an atomizing component. The atomizing component typically includes a liquid chamber and an air duct. The liquid chamber stores a liquid medium that evaporates after preheating, and the air duct carries the atomized liquid medium, formed after evaporation, out from the outlet side of the atomizing component. However, the inventors have discovered that existing atomizing components require a significant positive pressure to ensure the atomized liquid medium is smoothly blown out from the outlet side by the airflow. Current methods generally increase the volume of the air duct, typically by surrounding the liquid chamber. However, this inevitably reduces the volume of the liquid chamber, resulting in a smaller liquid capacity in the atomizing component and consequently a shorter lifespan. Utility Model Content

[0004] The purpose of this invention is to design a core and atomizing component for an atomizing assembly, which can greatly increase the volume of the liquid chamber of the atomizing assembly, thereby increasing the service life of the atomizing assembly.

[0005] To achieve the above objectives, embodiments of this utility model provide a core of an atomizing component, wherein the core is provided with a liquid cavity and an air duct; wherein, along the radial direction of the core, the air duct is located on one side of the liquid cavity, and the air duct and the liquid cavity are not interconnected.

[0006] In addition, some embodiments of this utility model also provide an atomizing component, including:

[0007] The core as described above;

[0008] The top cover device is rotatably disposed on the top of the core and is rotatable relative to the core; the top cover device has an air inlet side communicating with the air duct and an air outlet side for discharging gas;

[0009] Liquid-absorbing component; a portion of the liquid-absorbing component is inserted into the liquid cavity of the core for absorbing the liquid medium in the liquid cavity; another portion of the liquid-absorbing component is inserted into the upper cover device;

[0010] A heating element is disposed inside the upper cover device and connected to the liquid suction element, and is used to heat the liquid medium absorbed by the liquid suction element so that the liquid medium absorbed by the liquid suction element forms an atomized medium after being heated.

[0011] The upper cover device is used to connect the air inlet side and the air outlet side when rotating from the starting position to the ending position, so that the airflow through the air duct enters the upper cover device through the air inlet side and carries the atomizing medium out from the air outlet side.

[0012] The upper cover device is also used to disconnect the air inlet side and the air outlet side when rotating from the end position to the start position.

[0013] Compared to the prior art, the embodiments of this utility model, because the air duct is located radially along the core and on one side of the liquid cavity, and the air duct and the liquid cavity are not interconnected, can greatly increase the volume of the liquid cavity, allowing more liquid medium to be stored within it, thereby extending the service life of the atomizing component. Furthermore, the atomizing component also includes a top cover device positioned on the top of the core, and this top cover device is rotatable relative to the core. By rotating the top cover device in different directions, the air inlet and outlet sides of the top cover device can be connected or disconnected, and the airflow on the outlet side can be adjusted in real time during rotation.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0024] Example 1

[0025] The first embodiment of this utility model relates to a core of an atomizing component, such as... Figure 1 , Figure 3 and Figure 5 As shown, the core 1 is provided with a liquid cavity 11 and an air duct 12. The air duct 12 is located on one side of the liquid cavity 11 along the radial direction of the core 1, and the air duct 12 and the liquid cavity 11 are not connected to each other.

[0026] As can be seen from the above, since the air duct 12 is located on one side of the liquid cavity 11 along the radial direction of the core 1, and the air duct 12 and the liquid cavity 11 are not connected to each other, the volume of the liquid cavity 11 can be greatly increased, so that more liquid medium can be stored in the liquid cavity 11, thereby increasing and extending the service life of the atomizing component.

[0027] Specifically, in some embodiments, such as Figure 1 , Figure 3 and Figure 5 As shown, the volume of the air duct 12 is smaller than the volume of the liquid chamber 11, thereby greatly increasing the volume of the liquid chamber 11 and allowing it to store more liquid medium. For example, in some embodiments, the volume ratio of the air duct 12 to the liquid chamber 11 is 1:2 to 1:4.

[0028] Additionally, it is worth mentioning that, in order to ensure positive pressure when the airflow passes through the duct 12, in some embodiments, such as Figure 1 , Figure 3 and Figure 5 As shown, along the height direction of the core 1, the air duct 12 has an inlet 121 and an outlet 122 located away from the inlet 121. The air duct 12 extends vertically along the height direction of the core 1 from the inlet 121 to the outlet 122, so that the distance between the inlet 121 and the outlet 122 of the air duct 12 is the shortest. Therefore, the airflow does not interfere with the airflow when passing through the air duct 12, thereby avoiding energy loss when the airflow passes through the air duct 12. When the airflow is discharged through the outlet 122 of the air duct 12 and enters the upper cover device 2 of the atomizing component, the atomized medium formed by the liquid absorption component 3 of the atomizing component can be smoothly discharged from the outlet 122 of the atomizing component.

[0029] Of course, in some other embodiments, the air duct 12 may also include at least one irregularly shaped section from the inlet 121 to the outlet 122, so that the inlet 121 and the outlet 122 are staggered from each other along the height direction of the core 1 by the irregularly shaped section. This staggered inlet 121 and outlet 122 prevents the liquid droplets from directly entering the air duct 12 from the outlet 122 when the liquid suction component 3 drips, thus effectively protecting the blowing device that blows air into the air duct 12 and preventing the electrical performance of the blowing device from being affected by the backflow of liquid droplets through the air duct 12. Of course, in some embodiments, the irregularly shaped section may be an arc-shaped section, or in other embodiments, the irregularly shaped section may include at least one S-shaped channel, which can further prevent the phenomenon of liquid droplets flowing back into the blowing device through the air duct 12.

[0030] In addition, when the air duct 12 extends vertically from the inlet 121 to the outlet 122 along the height direction of the core 1, in order to further increase the positive pressure of the airflow when passing through the air duct 12, the air duct 12 gradually narrows from the inlet 121 to the outlet 122, so that the air duct 12 can be in a conical structure. Thus, when the airflow is discharged into the upper cover device 2 through the outlet 122 of the air duct 12, the positive pressure of the airflow when passing through the air duct 12 can be further increased.

[0031] Furthermore, in order to enable the formation of air ducts 12 and liquid chambers 11 within the core 1, and to ensure maximum utilization of the space within the core 1, in other embodiments, such as Figure 1 , Figure 3 and Figure 5 As shown, the core 1 includes: a housing 13 and a partition 14 disposed within the housing 13. The partition 14 divides the space within the housing 13 into an air duct 12 and a liquid chamber 11. It is noteworthy that the partition 14 can be integrally formed with the housing 13.

[0032] Example 2

[0033] Embodiment 2 of this utility model relates to an atomizing component, such as... Figure 1 and Figure 2 As shown, the atomizing component includes: a core 1, a top cover device 2, a liquid suction component 3, and a heating component 4 as described in Embodiment 1.

[0034] Among them, such as Figure 1 , Figure 3 and Figure 5 As shown, the top cover device 2 is rotatably mounted on the top of the core 1, and the top cover device 2 is also rotatable relative to the core 1. Furthermore, the top cover device 2 also has an air inlet side 21 communicating with the air duct 12 of the core 1, and an air outlet side 22 for discharging gas. Additionally, as... Figure 1 , Figure 3 and Figure 5 As shown, the liquid suction component 3 is partially inserted into the liquid cavity 11 of the core 1. The liquid suction component 3 can be used to draw liquid medium from the liquid cavity 11. At the same time, another part of the liquid suction component 3 is inserted into the upper cover device 2.

[0035] Finally, combining Figure 2 , Figure 4 and Figure 6 As shown, the heating element 4 is disposed within the upper cover device 2 and connected to the liquid suction element 3. For example, the heating element 4 can be a heating wire, which can be wound around the liquid suction element 3, thereby heating the liquid medium absorbed by the liquid suction element 3, causing the liquid medium absorbed by the liquid suction element 3 to form an atomized medium after being heated. Of course, in other embodiments, the heating element 4 can also be other types of heating elements, but in this embodiment, the type of heating element 4 is not specifically limited.

[0036] Furthermore, in some embodiments, such as Figure 1 and Figure 2 As shown, when the upper cover device 2 is rotated from the starting position to the ending position, it can connect the air inlet side 21 and the air outlet side 22, allowing the airflow through the air duct 12 to enter the upper cover device 2 through the air inlet side 21 and carry the atomizing medium out through the air outlet side 22. Conversely, as Figure 5 and Figure 6 As shown, the upper cover device 2 is also used to disconnect the air inlet side 21 and the air outlet side 22 when rotating from the end position to the start position.

[0037] As can be seen from the above, since the air duct 12 is located radially along the core 1 on one side of the liquid cavity 11 and is not connected to the liquid cavity 11, the volume of the liquid cavity 11 can be greatly increased, allowing more liquid medium to be stored within it, thereby extending the service life of the atomizing component. Simultaneously, the atomizing component also includes a top cover device 2 positioned on the top of the core 1, which is rotatable relative to the core 1. By rotating the top cover device 2 in different directions, the air inlet side 21 and the air outlet side 22 of the top cover device 2 can be connected or disconnected. Furthermore, during rotation, the airflow rate of the air outlet side 22 can be adjusted in real time. For example, when the atomizing component is a sachet, rotating the top cover device 2 can adjust the amount of fragrance emitted from the air outlet side 22, thereby achieving the purpose of adjusting the intensity of the ambient fragrance.

[0038] Specifically, in some embodiments, such as Figure 2 , Figure 4 and Figure 6 As shown, the upper cover device 2 includes a screw cap 23 and a mist outlet cap 26. The screw cap 23 is rotatably disposed on the top of the core body 1 and is rotatable relative to the core body 1. The screw cap 23 has a receiving space 211 along the height direction of the core body 1, and this receiving space 211 communicates with the air duct 12. Next, the mist outlet cap 26 is disposed within the receiving space 211. The mist outlet cap 26 can be assembled on the top of the core body 1 around the axis of the core body 1 with a first rotation angle or a second rotation angle, and can rotate relative to the core body 1 along with the screw cap 23. Finally, combined with… Figures 1 to 6 As shown, the side of the mist outlet cap 26 opposite to the core body 1 is the air inlet side 21, while the side of the mist outlet cap 26 away from the core body 1 is separated from the screw cap 23 to form the air outlet side 22. Furthermore, as... Figure 1 and Figure 2 As shown, the mist outlet cover 26, when rotated from the starting position to the ending position, can connect the air intake side 21 and the air outlet side 22. Simultaneously, as... Figure 5 and Figure 6 As shown, the mist cover 26 is also used to disconnect the air inlet side 21 from the air outlet side 22 when rotated from the end position to the start position.

[0039] Furthermore, it is worth noting that when the mist outlet cover 26 is assembled onto the core 1 at the first rotation angle, as... Figure 2 and Figure 7 As shown, the gas flow path when the air inlet side 21 and the air outlet side 22 are connected is the first path. When the mist outlet cover 26 is assembled onto the core 1 at the second rotation angle, as... Figure 4 and Figure 8 As shown, when the intake side 21 and the outlet side 22 are connected, the gas flow path is the second path, and the first path is different from the second path.

[0040] It is evident that since the mist outlet cover 26 can be assembled to the top of the core 1 at either a first rotation angle or a second rotation angle, and when the mist outlet cover 26 is assembled to the core 1 at the first rotation angle, the gas flow path when the air inlet side 21 and the air outlet side 22 are connected is the first path. When the mist outlet cover 26 is assembled to the core 1 at the second rotation angle, the gas flow path when the air inlet side 21 and the air outlet side 22 are connected is the second path, and the first path and the second path are different, it is clear that the mist outlet cover 26 can be installed on the core 1 at two different rotation angles. Therefore, while ensuring normal mist output from the mist outlet assembly, it also facilitates the assembly of the mist outlet assembly by the operator.

[0041] Furthermore, it is worth noting that, in order to allow the fog cover 26 to be assembled on top of the core 1 at two different rotation angles, such as... Figure 9 As shown, the fogging cover 26 can be provided with a first slot 261 and a second slot 262 along its circumference, and the first slot 261 and the second slot 262 are symmetrically arranged about the axis of the core 1. Corresponding to the first slot 261 and the second slot 262, as shown... Figure 9 As shown, the screw cap 23 has a first locking portion 231 and a second locking portion 232 arranged circumferentially, and the first locking portion 231 and the second locking portion 232 can also be arranged symmetrically about the axis of the core 1. The first locking portion 231 can be engaged in either the first locking slot 261 or the second locking slot 262, and similarly, the second locking portion 232 can also be engaged in either the first locking slot 262 or the second locking slot 262. For example, when the mist outlet cap 26 is assembled onto the core 1 at a first rotation angle, the first locking portion 231 can be engaged in the first locking slot 261, and the second locking portion 232 can be engaged in the second locking slot 262. Conversely, when the mist outlet cap 26 is assembled onto the core 1 at a second rotation angle, the second locking portion 232 can be engaged in the first locking slot 261, and the first locking portion 231 can be engaged in the second locking slot 262. Therefore, since the first slot 261 and the second slot 262, as well as the first latching part 231 or the second latching part 232 are all symmetrically arranged with the axis of the core 1 as the axis of symmetry, that is, there is an angle difference of 180 degrees between the first rotation angle and the second rotation angle, the fog cover 26 can be installed in both directions on the core 1. This means that when installing the fog cover 26, the operator does not need to consider the orientation of the fog cover during installation, which further improves the ease of assembly of the fog cover 26 and the assembly efficiency of the atomizing component.

[0042] Additionally, to allow the upper cover device 2 to rotate from the starting position to the ending position, the air inlet side 21 and the air outlet side 22 can be connected. Simultaneously, to allow the upper cover device 2 to rotate from the ending position to the starting position, the air inlet side 21 and the air outlet side 22 can be disconnected. In other embodiments, such as... Figure 2 , Figure 4 and Figure 6As shown, the atomizing assembly also includes a positioning member 24, which is disposed on the top of the core body 1 and engages with the positioning cap 23 along the axial direction of the core body 1, allowing the cap 23 to rotate relative to the core body 1. Wherein, as Figure 2 , Figure 4 and Figure 6 As shown, the mist outlet cover 26 can also be fastened to the positioning member 24, forming an atomizing area 25 between them for the liquid suction component 3 to be inserted. Furthermore, the positioning member 24 is also provided with a first air hole 241 and a second air hole 242 respectively communicating with the atomizing area 25. Therefore, when the cap 23 rotates the mist outlet cover 26, the first air hole 241 and the second air hole 242 are opened by the mist outlet cover 26 when the cap 23 rotates the mist outlet cover 26 from the starting position to the ending position, allowing the atomizing area 25 to communicate with the air inlet side 21 and the air outlet side 22 respectively. Figure 2 and Figure 4 The state shown. Conversely, the first air hole 241 and the second air hole 242 are also used to close the mist outlet cover 26 when the cap 23 drives the mist outlet cover 26 to rotate from the end position to the start position, so that the atomization zone 25 is disconnected from the air inlet side 21 and the air outlet side 22 respectively, as shown. Figure 6 The state shown.

[0043] Specifically, corresponding to the first vent 241 and the second vent 242, in some embodiments, such as Figure 2 , Figure 4 and Figure 6 As shown, the mist outlet cover 26 includes: a cover plate 263 and a side wall 264. The cover plate 263 is coaxially arranged with the screw cap 23 along the axial direction of the core 1, and is spaced apart from the screw cap 26 to form the air outlet side 22. Next, as... Figure 2 , Figure 4 and Figure 6 As shown, the sidewall 264 is connected to the cover plate 263 and is arranged around the axis of the core 1, and, combined with Figure 9 As shown, the first slot 261 and the second slot 262 are both provided on the side wall 264 of the mist outlet cover 26, so that the side wall 264 can be locked and fixed with the screw cap 23. Additionally, as... Figure 2 , Figure 4 and Figure 6 As shown, the sidewall 264 and the positioning member 24 form an atomizing area 25, and the side of the sidewall 264 away from the cover plate 263 is the air intake side 21. Simultaneously, the sidewall 264 is also provided with an exhaust port 265 communicating with the air outlet side 22. When the mist outlet cover 26 is assembled onto the core 1 at a first rotation angle, as... Figure 1 and Figure 2As shown, the exhaust port 265 is used so that when the mist outlet cover 26 rotates from the starting position to the ending position, it faces the first air hole 241, allowing the airflow through the air inlet side 21 to enter the atomization zone 25 through the second air hole 242, and then be discharged towards the air outlet side 22 after passing through the first air hole 241 and the exhaust port 265. Conversely, when the mist outlet cover 26 is assembled on the core body 1 at the second rotation angle, as... Figure 3 and Figure 4 As shown, the exhaust port 265 is used to face the second air port 242 when the mist cover 26 rotates from the starting position to the ending position, so that the airflow from the air intake side 21 enters the atomization zone 25 from the first air port 241, and is discharged towards the air outlet side 22 after passing through the second air port 242 and the exhaust port 265.

[0044] Furthermore, to allow the mist outlet cover 26 to rotate from the end position to the start position, the first air hole 241 and the second air hole 242 can be closed, so that the atomizing zone 25 can be disconnected from the air inlet side 21 and the air outlet side 22, respectively. In other embodiments, such as Figure 2 , Figure 4 and Figure 6 As shown, the mist outlet cover 26 further includes a sealing member 266, which is used to close the first vent 241 and the second vent 242 when the mist outlet cover 26 is rotated from the end position to the start position. Specifically, as Figure 2 , Figure 4 and Figure 6 As shown, the seal 266 includes: a top 2661 that fits against the cover plate 263, and a side portion 2662 formed circumferentially around the top 2661, with the side portion 2662 fitting against the side wall 264. Furthermore, the side portion 2662 is provided with an air outlet 2663 communicating with the exhaust port 265, and an air inlet notch 2664 is provided on the side of the side portion 2662 away from the top 2661, extending vertically towards the top 2661. Therefore, when the mist cover 26 is assembled onto the core 1 at a first rotation angle, as... Figure 1 and Figure 2 As shown, the air inlet 2664 is used to connect with the air duct 12 and the second air hole 242 respectively when the mist cover 26 rotates from the starting position to the ending position. This allows the airflow entering the air duct 12 to be guided into the atomizing zone 25 through the second air hole 242, and finally, the airflow entering the atomizing zone 25 passes sequentially through the first air hole 241, the air outlet 2663, and the exhaust hole 265 before being discharged from the air outlet side 22. That is, the airflow at this time flows along the path shown by the arrow in 7. When the mist cover 26 is assembled onto the core 1 at the second rotation angle, as shown... Figure 3 and Figure 4As shown, the air inlet 2664 is used to connect with the air duct 12 and the first air hole 241 respectively when the mist cover 26 rotates from the starting position to the ending position. This allows the airflow entering the air duct 12 to be guided into the atomization zone 25 through the first air hole 241, and finally the airflow entering the atomization zone 25 is discharged from the air outlet side 22 after passing through the second air hole 242, the air outlet 2663 and the exhaust hole 265 in sequence. That is, the airflow at this time flows along the path shown by the arrow in 8.

[0045] It is worth noting that since the liquid medium stored in the liquid chamber 11 of the atomizing component can be a volatile and easily leaking medium such as aromatherapy liquid, in order to ensure the sealing performance of the sealing member 266 on the first air hole 241 and the second air hole 242 when the mist outlet cover 26 rotates from the end position to the start position, so that the liquid medium in the liquid chamber 11 will not leak out or evaporate during the transportation of the atomizing component, in some embodiments, the sealing member 266 can be a flexible member, such as a rubber member, silicone member, or other sealing element, so that the sealing member 266 can be connected to the cover plate 263 and the side wall 264 by bonding or snap-fitting. Of course, in other embodiments, the sealing member 266 can also be other sealing members, such as rigid sealing members, but in this embodiment, the type of sealing member 266 is not specifically limited.

[0046] Additionally, it is worth mentioning that, in order to allow airflow through the positioning element 24 while simultaneously positioning the cap 23 along the axial direction of the core 1, in other embodiments, such as... Figure 2 , Figure 4 and Figure 6 As shown, the positioning component 24 includes: a base 243, a plug 244, and a locking portion 245. Meanwhile, as... Figure 1 , Figure 3 and Figure 5 As shown, the core 1 further includes a mounting base 15 disposed on the top of the housing 13. This mounting base 15 can be inserted into the liquid chamber 11 from the top of the housing 13, allowing the mounting base 15 to seal the liquid chamber 11. Figure 2 , Figure 4 and Figure 6 As shown, the base 243 is connected to the mounting base 15 along a preset axis, and the base 243 is provided with a through hole 246 for the liquid-absorbing component 3 to be inserted into the atomizing zone 25. Next, the plug 244 is provided on the side of the base 243 away from the mounting base 15, and forms the atomizing zone 25 with the mist outlet cover 26. The plug 244 is provided with a first air hole 241 and a second air hole 242 on the side away from the base 243. Finally, the snap-fit ​​part 245 is coaxially arranged with the plug 244 along a preset axis, and snaps the cap 23 to the top of the core 1.

[0047] In addition, through Figure 2 , Figure 4 and Figure 6 It is easy to see that the snap-fit ​​part 245 also forms an annular space 248 with the plug 244, and the annular space 248 can be inserted into the side part 2662 and side wall 264 of the mist outlet cover 26, so that the mist outlet cover 26 can rotate relative to the core body 1. Furthermore, when the mist outlet cover 26 is assembled on the core body 1 at the second rotation angle, the airflow through the air duct 12 enters the atomization zone 25 through the first air hole 241 on the positioning member 24. That is, the first air hole 241 and the air duct 12 are in a connected state at this time. Therefore, in order to achieve this state, the plug 244 is also provided with an air intake channel 247 connected to the air duct 12 on the side facing the base 243, and the air intake channel 247 extends around the axis of the core body 1, so that the air intake channel 247 can be connected to the annular space 248 and the air duct 12 respectively.

[0048] It is not difficult to see from the structure of the positioning component 24 described above that when the mist outlet cover 26 is assembled onto the core 1 at the first rotation angle, as Figure 2 and Figure 7 As shown, the air intake channel 247 is used to disconnect from the first air hole 241 when the mist outlet cover 26 rotates from the starting position to the ending position, so that the airflow through the air duct 12 can enter the atomization zone 25 sequentially through the air intake notch 2664 and the second air hole 242. When the mist outlet cover 26 is assembled onto the core 1 at the second rotation angle, as... Figure 4 and Figure 8 As shown, the air intake channel 247 is used to connect with the first air hole 241 through the air intake notch 2664 when the mist cover 26 rotates from the starting position to the ending position, so that the airflow in the air duct 12 can enter the atomization zone 25 in sequence through the air intake channel 247, the air intake notch 2664 and the first air hole 241.

[0049] Furthermore, in order to enable the snap-fit ​​portion 245 to snap onto the screw cap 23, in other embodiments, such as Figure 9 As shown, the screw cap 23 includes: an outer wall 233 surrounding the axis of the core 1, and an annular protrusion 234 protruding from the inner side of the outer wall 233 in a direction away from the outer side. Furthermore, combined with... Figure 2 , Figure 4 and Figure 6 As shown, corresponding to the annular protrusion 234, the snap-fit ​​portion 245 of the positioning member 24 includes: an annular sidewall 2451, an annular protrusion 2452, and a plurality of snap fasteners 2453.
