Detailed Implementation

[0042] 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.

[0043] 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.

[0044] 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).

[0045] In related technologies, an atomizer is a device that can heat and atomize a matrix to produce an aerosol. For example, a medical atomizer can atomize liquid medicine for treatment, or an electronic cigarette can heat and atomize e-liquid to produce an aerosol for the user to inhale.

[0046] The aerosol produced by the atomizing core atomizes the atomizing matrix and is output through the aerosol channel. During output, the aerosol easily condenses, producing condensate. The condensate and atomizing matrix flow back under their own gravity and seep out through the atomizing core, eventually leaking through the air intake channel on the atomizer. Typically, the air intake channel is designed with a meandering shape to prolong the leakage time; however, this method is not very effective at preventing leaks, and leakage still occurs over time. Simultaneously, some condensate or recirculated atomizing matrix remains in the air intake channel. When the airflow passes through the air intake channel, the condensate or recirculated atomizing matrix is ​​carried along, causing the condensate or recirculated atomizing matrix to fluctuate against the channel wall or be torn into small droplets. In this situation, the interaction between the gas and liquid generates noise, further affecting the user experience.

[0047] Even worse, when the refluxed condensate or atomizing matrix comes into contact with the airflow sensor used to start the atomizer core, there is a problem of corrosion or even self-restart of the airflow sensor, which in turn sends the wrong "work" control signal to the atomizer core, easily causing the core to burn out.

[0048] To address the aforementioned problems, this application provides an atomizer and atomizing device that uses a trap to trap backflowing condensate or atomizing matrix, thereby reducing leakage issues.

[0049] See Figures 1-18 As shown, the atomizer 100 provided in this embodiment includes an atomizing shell 10, an atomizing core 20, and a trapping groove 30.

[0050] The atomizing shell 10 has a relatively independent liquid storage chamber 11 and a trapping chamber 12 inside. The liquid storage chamber 11 is provided with an atomizing channel 13, which is the inner cavity of an atomizing tube 130 disposed in the liquid storage chamber 11. The inner cavity of the atomizing tube 130 is a hollow structure with openings at both ends. The atomizing channel 13 extends through the opposite ends of the liquid storage chamber 11 in the height direction. The atomizing channel 13 has a first atomizing hole 131 and a second atomizing hole 132, which are located at opposite ends of the liquid storage chamber 11 in the height direction, respectively. The trapping chamber 12 is located below the liquid storage chamber 11 where the second atomizing hole 131 is located, and the trapping chamber 12 communicates with the second atomizing hole 132.

[0051] Combination Figure 2 , Figure 3 , Figure 11 and Figure 12 As shown, the atomizing core 20 is installed in the atomizing channel 13. The liquid storage chamber 11 can be used to store the atomizing matrix and can provide the stored atomizing matrix to the atomizing core 20. The atomizing core 20 can heat and atomize the atomizing matrix to generate an aerosol.

[0052] In a specific embodiment, the atomizing core 20 includes a liquid guiding component 21 and a heating component 22. The liquid guiding component 21 is installed inside the atomizing tube 130, and a portion of the liquid guiding component 21 can extend out of the atomizing tube 130 and into the liquid storage chamber 11. That is, the liquid guiding component 21 is installed in the atomizing channel 13, and a portion of the liquid guiding component 21 extends out of the atomizing channel 13 into the liquid storage chamber 11. The liquid guiding component 21 is provided with a through mounting channel 210, and the heating component 22 is fitted to the mounting channel 210.

[0053] In some embodiments, the liquid storage chamber 11 is further provided with a liquid storage component 111. Both the liquid storage component 111 and the liquid guiding component 21 are made of fiber cotton. The portion of the liquid guiding component 21 extending into the liquid storage chamber 11 contacts the liquid storage component 111. The atomizing matrix is ​​in liquid form. The liquid storage component 111 stores the atomizing matrix by adsorption and transfers the atomizing matrix to the liquid guiding component 21 through capillary action. The atomizing matrix is ​​then transferred to the heating component 22 through the liquid guiding component 21. The heating component 22 can generate heat when energized to heat the atomizing matrix. The generated aerosol enters the atomization channel 13 and is output through the first atomization hole 131.

[0054] During the output process, the aerosol matrix is ​​prone to condensation, which will flow back into the atomization channel 13 under its own gravity. In addition, some of the atomization matrix will also flow back into the atomization channel 13 under the action of the liquid guide 21. The condensate or atomization matrix flowing back into the atomization channel 13 will flow out through the second atomization hole 132 under its own gravity, causing leakage.

[0055] To address the aforementioned leakage issue, this application further includes an interception tank 30 installed within the interception chamber 12. The opening of the interception tank 30 faces the second atomization hole 132. The condensate or atomization matrix flowing back through the second atomization hole 132 is intercepted by the interception tank 30. Therefore, the interception tank 30 can be used to contain liquids leaking from or flowing back from the atomization channel 13. The leaked liquid is the atomization matrix seeping through the liquid guide 21, and the flowing back liquid is the flowing back condensate.

[0056] In this application, the atomizing matrix, after being heated by the heating element 22, produces a granular atomizing matrix. This granular atomizing matrix needs to be mixed with external air to form an aerosol. Furthermore, the external air can form a flowing airflow in the atomization channel 13 to facilitate the output of the aerosol from the first atomization hole 131. For facilitating the entry of external air, see [reference needed]. Figure 2 , Figure 3 , Figure 11 and Figure 12 As shown, a portion of the sidewall of the trapping tank 30 is sealed to the side of the liquid storage chamber 11 facing the trapping chamber 12, thus forming a closed tank structure. An air passage 31 is provided on the bottom wall of the trapping tank 30, which communicates with the atomizing channel 13. The atomizing shell 10 has an air inlet channel 14 communicating with the trapping chamber 12, allowing external air to enter through it. The air passage 31 communicates with the air inlet channel 14, enabling external air to enter through the air passage 31 into the atomizing channel 13, facilitating the generation of aerosols and their output from the first atomizing hole 131 under the action of airflow.

[0057] In this embodiment, an air passage 31 is provided on the bottom wall of the interception tank 30, so that external air can enter the atomization channel 13 through the air passage 31. After the leaked or backflowing liquid is intercepted by the interception tank 30, residual liquid can be avoided from adhering to the air passage wall through which the external air flows, thereby avoiding the problem of noise generated by airflow and residual liquid.

[0058] To prevent leakage or backflow of liquid contained in the trapping tank 30 from the vent 31, this application also provides an annular stop 32 around the vent 31 on the bottom wall of the trapping tank 30. The annular stop 32 extends from the bottom wall of the trapping tank 30 toward the opening of the trapping tank 30 to block the leakage or backflow of liquid contained in the trapping tank 30.

[0059] To extend the lifespan of this atomizer 100, please refer to [link / reference]. Figures 5-7 ,and Figures 14-16 As shown, the atomizer 100 also includes a liquid supply chamber 40, which is used to provide atomizing matrix to the liquid storage chamber 11, specifically to replenish the liquid storage chamber 11 with atomizing matrix.

[0060] The liquid supply chamber 40 is provided with an aerosol channel 41 through it. The liquid supply chamber 40 is provided with a first assembly part 42, and the atomizing shell 10 is provided with a second assembly part 15. The first assembly part 42 and the second assembly part 15 are detachably connected. For example, the first assembly part 42 and the second assembly part 15 can be detachably connected by means of snap-fit ​​connection, bolt connection, etc., so that the liquid supply chamber 40 and the atomizing shell 10 can be detachably connected. After the first assembly part 42 and the second assembly part 15 are connected, the first atomizing hole 131 is sealed and connected to the aerosol channel 41. The aerosol output from the first atomizing hole 131 can be output through the aerosol channel 41.

[0061] See also Figures 5-7 ,and Figures 14-16 As shown, the liquid supply chamber 40 is also equipped with a suction nozzle 43, which has a suction nozzle channel 431. The suction nozzle channel 431 is connected to the aerosol channel 41. In actual use, the user can use the suction nozzle 43 to draw air, so that external air can enter the atomization channel 13 through the air inlet channel 14, the air passage 21, and the second atomization hole 132. The resulting airflow can heat the atomized aerosol generated by the heating element 22 and then output it through the atomization channel 13 and the aerosol channel 41 in sequence, and then output it through the suction nozzle channel 431 for the user's use.

[0062] Since the liquid supply chamber 40 and the atomizing shell 10 are detachably connected, to facilitate the supply of the atomizing matrix from the liquid supply chamber 40 to the liquid storage chamber 11, see [link to previous section] for more details. Figure 6 and Figure 15 As shown, a sealing element 44 is also provided at the bottom of the liquid supply chamber 40. The sealing element 44 may be made of silicone and has a punctureable area 441, which may be a thin film. A puncture tube 16 is also provided on the atomizing shell 10. The puncture tube 16 protrudes from the end of the atomizing shell 10 where the first atomizing hole 131 is provided and communicates with the liquid storage chamber 11. When the first assembly part 42 is connected to the second assembly part 15, the puncture tube 16 is configured to puncture the punctureable area 16 to connect the liquid supply chamber 40 and the liquid storage chamber 11, so that the atomized matrix stored in the liquid supply chamber 40 can enter the liquid storage chamber 11 through the puncture tube 16 to provide the atomized matrix to the liquid storage chamber 11.

[0063] After the liquid supply chamber 40 and the atomizing shell 10 are connected to the second assembly part 15 via the first assembly part 42, it is necessary to ensure that the second atomizing hole 132 and the aerosol channel 41 are sealed and connected. To this end, in this application, a vent pipe 17 is also provided on the side of the atomizing shell 10 where the first atomizing hole 131 is located. This vent pipe 17 connects to the first atomizing hole 131 and can be considered as a tubular structure protruding outward from the first atomizing hole 131. When the first assembly part 42 and the second assembly part 15 are connected, the vent pipe 17 is sealed and inserted into the aerosol channel 41 to indirectly achieve a sealed connection between the first atomizing hole 131 and the aerosol channel 41.

[0064] The returned condensate or leaked atomizing matrix drips down the channel wall of the atomizing channel 13 from the wall of the second atomizing hole 132 into the intercepting tank 30 under its own gravity. To ensure that the returned condensate or leaked atomizing matrix can completely drip into the intercepting tank 30, see [reference needed]. Figure 3 and Figure 12 As shown, the diameter of the second atomizing hole 132 is larger than the diameter of the air passage hole 31. At the same time, the second atomizing hole 132 and the air passage hole 31 are coaxial, and the orthographic projection of the air passage hole 31 on the bottom of the intercepting tank 30 is located within the orthographic projection area of ​​the second atomizing hole 132 on the bottom of the intercepting tank 30.

[0065] In one embodiment of this application, see Figure 3 As shown, the second atomizing hole 132 has a first conical guide surface 133 on its hole wall. The first conical guide surface 133 is arranged around the axis of the second atomizing hole 132 on the hole wall to form an annular shape. The end with the largest diameter of the first conical guide surface 132 faces the air passage 31. The first conical guide surface 133 can guide the backflow of condensate or the leakage of atomizing matrix. The first conical guide surface 132, which is set as a cone, can ensure that the backflow of condensate or the leakage of atomizing matrix can completely drip into the interception tank 30.

[0066] In another embodiment of this application, see [link to application]. Figure 12 As shown, the annular stop 32 has a second conical guide surface 321 on the outer surface of the side wall of the intercepting tank 30. The second conical guide surface 321 is arranged around the axis of the air passage 31 on one side of the annular stop 32 facing the side wall of the intercepting tank 30, forming an annular shape. The end with the smallest diameter of the second conical guide surface 321 faces the second atomizing hole 132. This arrangement allows the condensate or atomizing matrix dripping from the second atomizing hole 132 to drip onto the second conical guide surface 321 and be guided by the second conical guide surface 321 into the intercepting tank 30.

[0067] In this application, the first conical guide surface 133 may be provided only on the wall of the second atomizing hole 132, or the second conical guide surface 321 may be provided only on one side of the annular stop portion 32 facing the side wall of the intercepting groove 30. Of course, the first conical guide surface 133 may be provided on the wall of the second atomizing hole 132, and the second conical guide surface 321 may be provided on one side of the annular stop portion 32 facing the side wall of the intercepting groove 30. The specific choice can be made according to actual needs.

[0068] In some embodiments, when the amount of leaked or backflowed liquid contained in the trapping tank 30 reaches its maximum capacity, some liquid will leak from the vent 31. For this, see [link to relevant documentation]. Figure 2 , Figure 3 , Figure 6 , Figure 7 as well as Figure 11 , Figure 12 , Figure 15 and Figure 16 As shown, the atomizer 100 provided in this application also includes a liquid suction element 50, which is disposed in the interception chamber 12 and surrounded by an interception tank 30, and can absorb liquid leaking from the air passage 31.

[0069] In this embodiment, see Figure 3 and Figure 12 As shown, the liquid suction component 50 shields the air intake channel 14, and the air intake channel 14 is misaligned with the air passage 31. By shielding the air intake channel 14 with the liquid suction component 50, liquid leakage can be prevented from directly passing through the air intake channel 14, and impurities such as moisture in the external air entering during suction can also be filtered.

[0070] See Figures 1-18 As shown, the side wall of the intercepting groove 30 is provided with a clearance notch 33, and the atomizing core 20 is also provided with a pin 23. The pin 23 can electrically connect the atomizing core 20 to the external power supply device 200. When the pin 23 is led out, the clearance notch 33 is used to avoid the pin 23.

[0071] See Figure 8 and Figure 9 and Figure 17 and Figure 18 As shown, this application also provides an atomizing device 1000, including the atomizer 100 in the above embodiments. The atomizing device 1000 further includes a power supply device 200, which is detachably or non-detachably connected to the atomizer 100.

[0072] The power supply device 200 includes a power supply unit 201 and a housing 202. The housing 202 is hollow inside and open at one end and closed at the other. A mounting cavity 203 is formed in the inner cavity of the housing 202. The power supply unit 201 is installed at the bottom of the mounting cavity 203, and at least a portion of the atomizer 100 is installed in the mounting cavity 203 and is detachably or non-detachably connected to the mounting cavity 203. After the atomizer 100 is installed in the mounting cavity 203, the pin 23 can be electrically connected to the power supply unit 201 to supply electrical energy to the heating element 22 in the atomizer 100 through the power supply unit 201.

[0073] An air inlet (not shown in the figure) communicating with the mounting cavity 203 is also provided on the housing 202. The air inlet is connected to the air intake channel 14. An airflow sensor 204 is also provided in the mounting cavity 203 between the atomizer 100 and the power supply unit 201. The airflow sensor 204 is electrically connected to the heating element 22 in the atomizing core 20. When the user inhales through the mouthpiece 43, external air enters the air intake channel 14 through the air inlet. The air pressure changes during the external air flow. During this process, the airflow sensor 204 can sense the air pressure change to generate a control signal to control the operation of the atomizing core 20. Under the action of the control signal, the heating element 22 is controlled to heat and atomize the atomizing matrix.

[0074] Correspondingly, by setting the intercepting tank 30 as described above, when it contains leaked or backflowed liquid, it can avoid the problem of liquid backflow through the air intake channel 14 causing corrosion of the airflow sensor 204. At the same time, it can also avoid the problem of the airflow sensor 204 self-starting, causing the atomizing core 20 to burn out.

[0075] In summary, the atomizer and atomizing device provided by this utility model can avoid liquid leakage by intercepting the condensate or atomizing matrix that flows back through the second atomizing hole through the intercepting tank, thereby optimizing the user experience.

[0076] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. 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.
