Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to an atomization device. Background Technology

[0002] The atomizing matrix can be heated and atomized by the atomizing core in the atomizing device to produce an aerosol. To facilitate the control of the atomizing core, an airflow sensor is usually used to sense changes in airflow to control the atomizing core to start. That is, the user draws in outside air into the air intake channel, and the airflow sensor is set in the air intake channel. After sensing the change in airflow, the airflow sensor can generate a signal to control the operation of the atomizing core.

[0003] Atomizer cores typically have an aerosol channel through which aerosols are output and used by the user. During the aerosol output process, condensation is easily generated. When the condensation flows back to the airflow sensor, it can corrode the airflow sensor, further causing the airflow sensor to malfunction and affecting the user experience. Utility Model Content

[0012] The liquid inlet is disposed on the partition plate, and the height of the first detection air hole relative to the air inlet channel is higher than the height of the partition plate relative to the air inlet channel.

[0013] In one embodiment, at least two partitions are provided on one side of the bracket, the at least two partitions dividing the space enclosed by the annular convex wall into at least two condensation recovery chambers, and the space between the at least two partitions defining at least one air intake passage.

[0015] In one embodiment, the height of the liquid-absorbing element is higher than the height of the partition, and the first detection vent is spaced apart from the liquid-absorbing element.

[0016] In one embodiment, the detection channel is curved to extend the path length of the detection channel.

[0017] In one embodiment, the bracket is further provided with a vent hole, which is connected to the detection channel and the mounting groove;

This avoids the condensate from entering the mounting groove through the detection channel via the first detection air hole, thus preventing the condensate from corroding the airflow sensor and causing it to malfunction. This extends the service life of the airflow sensor and ensures that the user can use the atomizing device normally. Attached Figure Description

[0043] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0044] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0045] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0046] Atomizing devices typically consist of a liquid reservoir and an atomizing core assembly. The liquid reservoir contains a storage chamber for storing the atomizing matrix. The atomizing core assembly is installed within the atomization channel inside the liquid reservoir. The atomizing core assembly also includes an aerosol channel. Below the liquid reservoir is an airflow support, which has at least one detection channel connected to the atomization channel. An airflow sensor is mounted on the airflow support and installed in the detection channel. When using this atomizing device, the user draws air through the detection channel into the atomization channel. During this drawing process, the airflow sensor detects changes in air pressure flowing through the detection channel, thereby activating the atomizing core assembly.

[0047] In the aforementioned atomizing device, the atomizing channel and the air intake channel are usually coaxially arranged. During the atomization channel output process, the aerosol is prone to condensation and the condensate will flow back to the detection channel and corrode the airflow sensor, which will lead to damage to the airflow sensor or even failure, thus affecting the user experience.

[0048] To address the aforementioned issues, this application provides an atomizing device that allows the returned condensate to be collected by the condensation recovery chamber, preventing the condensate from flowing to the airflow sensor via the detection channel.

[0049] See Figures 1-9 As shown, the atomizing device 100 provided in this application includes a liquid storage tank 10, a bracket 20, and an airflow sensor 30.

[0050] The liquid storage chamber 10 is provided with an atomization channel 111. Inside the liquid storage chamber 10, there is a liquid storage component 11, which is used to store the liquid atomization matrix. The liquid storage component 11 is usually made of fiber cotton and can adsorb and store the atomization matrix by adsorption.

[0051] An atomizing core 40 is also provided in the atomizing channel 111. The atomizing matrix stored in the liquid storage device 11 can be conducted to the atomizing core 40, and the atomizing core 40 can heat and atomize the atomizing matrix to produce an aerosol.

[0052] The atomizing channel 111 typically extends through the height of the liquid storage chamber 10, while the atomizing core 40 has an aerosol channel 41 inside. After the atomizing core 40 is installed into the atomizing channel 111, the aerosol channel 41 and the atomizing channel 111 are coaxially arranged and interconnected. The aerosol generated by the heating and atomization of the atomizing core 40 can enter the atomizing channel 111 through the aerosol channel 41 and can then be output from the atomizing channel 111 for user use.

[0053] See Figures 4-8As shown, one side of the bracket 20 is connected to one end of the liquid storage tank 10, wherein one end of the liquid storage tank 10 is its height direction end. The bracket 20 is provided with an air intake channel 21. Since the atomizing channel 111 runs through the height direction of the liquid storage tank 10, the air intake channel 21 and the atomizing channel 111 can communicate. One side of the bracket 20 is provided with a boss 22 and a condensation recovery chamber 23. The boss 22 is provided with a mounting groove 24 (e.g., Figure 8 As shown in the figure, the boss 22 is located on one side of the bracket 20, while the slot of the mounting groove 24 is located on the other side of the bracket 20 opposite to the boss 22.

[0054] The boss 22 is also provided with a detection channel 25 and a first detection vent 26. The detection channel 25 connects the first detection vent 26 and the mounting groove 24, and the first detection vent 26 connects the detection channel 25 and the air inlet channel 21. The cavity wall of the condensation recovery chamber 23 is provided with a liquid inlet vent 231 that communicates with the air inlet channel 21. The height of the first detection vent 26 relative to the air inlet channel 21 is higher than the height of the liquid inlet vent 231 relative to the air inlet channel 21.

[0055] An airflow sensor 30 is disposed in the mounting slot 24 and is electrically connected to the atomizing core 40. The airflow sensor 30 can respond to changes in the air pressure signal of the detection channel 25 and then output an electrical signal to the atomizing core 40 to control the operation of the atomizing core 40. For the specific process of the airflow sensor 30 responding to changes in the air pressure signal, please refer to the following embodiments.

[0056] See Figure 2 , Figure 3 , Figure 5 as well as Figure 8 As shown, a mounting position 201 is also provided on the bracket 20, and a power supply unit 50 is mounted on the mounting position 201. The power supply unit 50 is electrically connected between the airflow sensor 30 and the atomizing core 40. Figures 1-3 As shown, the atomizing device 100 provided in this application also includes a housing 60, wherein the liquid storage chamber 10 and the bracket 20 are both installed inside the housing 60, and an air inlet 61 is provided at the bottom end of the housing 60 (e.g., Figure 2 As shown), the air inlet 61 is connected to the air inlet channel 21, and the top of the outer shell 60 is also provided with a nozzle 62, which has a nozzle channel 621 and is connected to the atomization channel 111.

[0057] In some embodiments, a sealing element 622 is also provided in the mouthpiece channel 621 of the mouthpiece 62. The sealing element 622 can block the mouthpiece channel 621 when the atomizing device 100 is not in use, so as to prevent foreign objects from entering the product through the mouthpiece channel 621 and affecting the normal use of the product.

[0058] In actual use, the user draws air through the nozzle 62, creating a negative pressure in the nozzle channel 621, atomization channel 111, and air intake channel 21. External gas can enter the atomization channel 111 through the air intake port 61 along the air intake channel 21. As the external gas passes through the air intake channel 21, it creates a negative pressure in the detection channel 25 through the first detection port 26. Since the detection channel 25 is connected to the mounting slot 24, the airflow sensor 30 can sense the change in air pressure signal in the detection channel 25, thereby generating an air pressure change signal. This air pressure change signal is then transmitted to the atomizing core 40, which controls the operation of the atomizing core 40. The atomizing core 40 heats and atomizes the atomizing matrix stored in the liquid storage component 11 to produce an aerosol. Under the action of external gas, the aerosol is output from the nozzle channel 621 through the atomization channel 111 for the user's use.

[0059] During the process of aerosol being output from nozzle channel 621 through atomization channel 111, due to the long transmission path, the aerosol condenses when the temperature changes, producing condensate. Under its own gravity, the condensate can flow back to air intake channel 21 through atomization channel 111. Since the height of the first detection air hole 26 relative to air intake channel 21 is higher than the height of the liquid inlet hole 231 relative to air intake channel 21, the refluxed condensate enters the condensation recovery chamber 23 through liquid inlet hole 231 and is recovered. This avoids the condensate from entering the mounting groove 24 through detection channel 25 via the first detection air hole 26, thus preventing the condensate from corroding the airflow sensor 30 and causing it to malfunction, thereby extending the service life of the airflow sensor 30.

[0060] See Figures 4-7 As shown, the detection channel 25 is a groove-shaped structure. After connecting one side of the support 20 to one end of the liquid storage tank 10, the groove-shaped structure can be closed through one end of the liquid storage tank 10 to form the detection channel 25. Of course, the detection channel 25 can also be a channel structure formed inside the support 20.

[0061] The air intake channel 21 is partially a groove-shaped structure. Similarly, after connecting one side of the support 20 to one end of the liquid storage tank 10, the groove-shaped structure can be closed through one end of the liquid storage tank 10 to form a complete air intake channel 21. Likewise, the air intake channel 21 can be a channel structure formed inside the support 20.

[0062] In this embodiment, the detection channel 25 is a groove-shaped structure and the air intake channel 21 is a groove-shaped structure as an example. The groove-shaped structure can facilitate the manufacturing of the detection channel 25 and the air intake channel 21, simplifying the manufacturing difficulty of the product.

[0063] See Figure 2 , Figure 3 , Figure 5 , Figure 6 as well as Figure 9 As shown, the liquid storage chamber 10 includes a chamber body 12 and a bottom cover 13. The bottom end of the chamber body 12 has an opening structure, and the bottom cover 13 is sealed and installed at the opening structure at the bottom end of the chamber body 12. The liquid storage component 11 is installed within the space enclosed by the bottom cover 13 and the chamber body 12, and the atomizing channel 111 is located in the middle of the liquid storage component 11. A connecting hole 131 is also provided on the bottom cover 13, which communicates with the atomizing channel 111. One side of the bracket 20 is connected to the bottom cover 13. After connecting one side of the bracket 20 to the bottom cover 13, the connecting hole 131 maintains communication with the air inlet channel 21 and the first detection air port 26.

[0064] Correspondingly, the end of the bottom cover 13 facing away from the chamber 12 is sealed in conjunction with the groove-shaped detection channel 25 and the partially groove-shaped air intake channel 21.

[0065] To improve the seal between the bottom cover 13 and the bracket 20, see Figure 2 , Figure 3 , Figures 5-9 As shown, one side of the support 20 is also provided with an annular protrusion 202. The annular protrusion 202 is a ring-shaped structure that protrudes from one side of the support 20. One end of the liquid storage tank 10 is provided with a slot 132, which is a groove-shaped structure formed at one end of the liquid storage tank 10. Specifically, the slot 132 is located on the side of the bottom cover 13 facing away from the tank body 12. After connecting one side of the support 20 to one end of the liquid storage tank 10, the annular protrusion 202 can be inserted into the space enclosed by the slot 132. Through the cooperation of the annular protrusion 202 and the slot 132, the effect of sealing one side of the support 20 and one end of the liquid storage tank 10 can be achieved.

[0066] It is understood that the connecting hole 131 is located inside the slot 132, and at least part of the air intake channel 21, the condensation recovery chamber 23, the detection channel 25 and the first detection air hole 26 are located within the space enclosed by the annular convex wall 202.

[0067] like Figures 5-7 As shown, a partition 27 is also provided on one side of the bracket 20. The partition 27 is arranged along the length of the air intake channel 21. The partition 27 divides the space enclosed by the annular convex wall 202 into the air intake channel 21 and the condensation recovery chamber 23. The boss 22 is located inside the condensation recovery chamber 23.

[0068] The condensation recovery chamber 23 is also a trough-shaped structure. It can be obtained by connecting one side of the support 20 to one end of the liquid storage tank 10, and then sealing the trough-shaped structure through the bottom cover 13 on the side facing away from the tank body 12.

[0069] The liquid inlet 231 is provided on the partition 27. Specifically, the liquid inlet 231 is a notch structure formed on the partition 27, and the height of the first detection air hole 26 relative to the air inlet channel 21 is higher than the height of the partition 27 relative to the air inlet channel 21.

[0070] In this embodiment, at least two partitions 27 are provided on one side of the bracket 20. The at least two partitions 27 divide the space enclosed by the annular convex wall 202 into at least two condensation recovery chambers 23, and the space between the at least two partitions 27 defines at least one air intake passage 21. It should be noted that the boss 22 provided on one side of the bracket 20 is located in one of the condensation recovery chambers 23.

[0071] After the refluxed condensate enters the condensation recovery chamber 23 through the liquid inlet 231 and is collected, to prevent the condensate from leaking from the liquid inlet 231 into the air intake channel 21, see [reference needed]. Figures 3-6 As shown, the atomizing device 100 provided in this embodiment also includes a liquid suction element 70, which is disposed in the condensation recovery chamber 23. In other words, a liquid suction element 70 is provided in each condensation recovery chamber 23, and the condensate that enters the condensation recovery chamber 23 through the liquid inlet hole 231 is adsorbed and collected by the liquid suction element 70.

[0072] In one of the condensation recovery chambers 23 with the boss 22, a liquid suction element 70 is provided in a portion of the area. In other words, the volume of the liquid suction element 70 in the condensation recovery chamber 23 without the boss 22 is significantly larger than the volume of the liquid suction element 70 in the condensation recovery chamber 23 with the boss 22.

[0073] Since the first detection vent 26 is located on the boss 22, it is positioned so that it faces the liquid suction member 70 in the condensation recovery chamber 23 where the boss 22 is located. This arrangement ensures that when some condensate flows toward the first detection vent 26, that portion of the condensate can be quickly absorbed by the liquid suction member 70.

[0074] In this embodiment, the height of the liquid suction member 70 is higher than the height of the partition 27. In a specific embodiment, the first detection vent 26 and the liquid suction member 70 can be spaced apart. This ensures that the external gas entering the air inlet channel 21 can pass through the first detection vent 26 to generate negative pressure in the detection channel 25, while the liquid suction member 70 can also adsorb and collect the condensate flowing towards the first detection vent 26.

[0075] In this application, the atomizing core 40 atomizes the atomizing matrix to generate atomized particles. The atomized particles mixed with external gas form an aerosol. When some aerosol flows back or external gas enters the detection channel 25, there is a possibility that liquid molecules (e.g., water molecules) may enter the mounting groove 24 through the detection channel 25 and come into contact with the airflow sensor 30. Thus, with the long-term accumulation of liquid molecules, the airflow sensor 30 is easily corroded and damaged. Therefore, in this embodiment, the detection channel 25 is set to a curved shape. The curved shape of the detection channel 25 can extend its path length in a unit space, thereby allowing liquid molecules (e.g., backflowing aerosol or water molecules in external gas) to condense and adhere to the channel wall of the detection channel 25 during the transmission of the longer path of the detection channel 25. Some liquid molecules can also collide with the channel wall of the curved detection channel 25 to adhere to the channel wall of the detection channel 25. Even if the liquid molecules adhering to the channel wall of the detection channel 25 form liquid, it is prevented from directly reaching the airflow sensor 30.

[0076] In this embodiment, the curved detection channel 25 can be spiral, S-shaped, right-angled, or other shapes. This increases the contact area between liquid molecules and the channel wall of the detection channel 25, while also making the structure of the detection channel 25 more compact.

[0077] In some embodiments, the bottom wall of the detection channel 25 can be configured as an inclined structure, with the lowest end of the bottom wall of the inclined detection channel 25 connected to the first detection vent 26, and the highest end of the bottom wall of the inclined detection channel 25 connected to the mounting groove 24. In this way, even if liquid molecules form condensate due to contact with the channel wall of the detection channel 25, it will first be discharged into the air inlet channel 21 through the first detection vent 26, and then be adsorbed and collected by the liquid suction element 70 in the condensation recovery chamber 23 through the liquid inlet 231.

[0078] See Figure 4 , Figure 7 as well as Figure 8 As shown, the bracket 20 is also provided with a vent 221, which penetrates the detection channel 25 and the mounting groove 24 so that the vent 221 is connected to the detection channel 25 and the mounting groove 24.

[0079] See Figures 4-9As shown, the boss 22 has a first annular protrusion 28 and a plurality of second annular protrusions 29, wherein the plurality of second annular protrusions 29 are nested in layers and spaced apart. The first annular protrusion 28 is spaced out on the outermost layer of the second annular protrusions 29, that is, it is spaced outside the outermost second annular protrusion 29 among all the second annular protrusions 29. A first detection air hole 26 is provided on the first annular protrusion 28, and the second annular protrusion 29 is provided with a second detection air hole 291, and the second detection air hole 291 is offset from the first detection air hole 26. The space between the outermost layers of the first annular protrusion 28 and the second annular protrusion 29, and the space between two adjacent second annular protrusions 29 define the detection channel 25. The space between the outermost layers of the first annular protrusion 28 and the second annular protrusion 29 is the space between the first annular protrusion 28 and the outermost second annular protrusion 29 among all the second annular protrusions 29. The first detection vent 26 and the second detection vent 291 constitute the air inlet and air outlet of the detection channel 25. The staggered arrangement of the first detection vent 26 and the second detection vent 291 can effectively extend the length of the detection channel 25 and make the detection channel 25 form a curved shape.

[0080] like Figure 7 As shown, the first detection vent 26 and the second detection vent 291 are on the same straight line. This arrangement allows the detection channel 25 to reach its maximum path length.

[0081] See Figures 4-6 as well as Figure 9 One end of the liquid storage tank 10 is provided with a third annular protrusion 133, which is specifically located at the end of the bottom cover 13 facing away from the tank body 12. The third annular protrusion 133 is nested outside the first annular protrusion 28. The third annular protrusion 133 can seal the opening of the groove-shaped detection channel 25. A third detection air hole 134 is provided on the side wall of the third annular protrusion 133. The third detection air hole 134 is interconnected with the first detection air hole 26 and the air inlet channel 21, so that the external gas flowing through the air inlet channel 21 can cause a pressure change in the detection channel 25 through the third detection air hole 134 and the first detection air hole 26.

[0082] In this application, the first detection vent 26, the second detection vent 291, and the third detection vent 134 are notch structures respectively provided on the sidewalls of the first annular protrusion 28, the second annular protrusion 29, and the third annular protrusion 133. Of course, the first detection vent 26, the second detection vent 291, and the third detection vent 134 can also be through hole structures respectively provided on the sidewalls of the first annular protrusion 28, the second annular protrusion 29, and the third annular protrusion 133.

[0083] To prevent condensate flowing back into the air intake channel 21 from flowing through the air intake port 61 to the outer surface of the housing 60 of the atomizing device 100, see [reference needed]. Figure 2 , Figure 6 and Figure 7 As shown, the air intake channel 21 includes a first air intake section 211 and a second air intake section 212 that are interconnected, and a blocking part 213 disposed between the first air intake section 211 and the second air intake section 212. The third detection air hole 134 is connected to the first air intake section 211. The second air intake section 212 penetrates the height direction of the bracket 20 and is connected to the air intake hole 61 disposed on the outer shell 60. After the external gas enters the air intake channel 21 through the air intake hole 61, the air pressure changes in the detection channel 25 can be generated through the third detection air hole 134 and the first detection air hole 26.

[0084] In this embodiment, the first air inlet section 211 is also connected to the liquid inlet hole 231. The height of the blocking part 213 is higher than the bottom wall of the air inlet channel 21. The refluxed condensate is blocked by the blocking part 213 in the first air inlet section 211 and is adsorbed and collected by the liquid suction member 70 in the condensation recovery chamber 23 through the liquid inlet hole 231.

[0085] In summary, in the atomizing device provided by this application, the aerosol generates condensate due to temperature changes during the output process. Under its own gravity, the condensate flows back to the air inlet channel 21 through the atomizing channel 111. Since the height of the first detection port 26 relative to the air inlet channel 21 is higher than the height of the liquid inlet port 231 relative to the air inlet channel 21, the refluxed condensate enters the condensation recovery chamber 23 through the liquid inlet port 231 and is recovered. This avoids the condensate from entering the mounting groove 24 through the detection channel 25 via the first detection port 26, thus preventing the condensate from corroding the airflow sensor 30 and causing it to malfunction. This extends the service life of the airflow sensor 30 and ensures that the user can use the atomizing device 100 normally.

Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
