Abstract
Description
Technical Field
[0001] This utility model relates to the field of atomization technology, and in particular to an electronic atomization device. Background Technology
[0002] An electronic atomizing device is a device that heats and atomizes an atomizing matrix to generate an aerosol. To prevent leakage of the liquid matrix from gaps in the components, electronic atomizing devices require numerous sealing components. For example, some electronic atomizing devices in related technologies use an airflow sensor to trigger activation. To prevent leakage of condensate or atomizing liquid from adversely affecting the airflow sensor, a separate sealing component is usually required to mount and secure the airflow sensor. Another example is the liquid injection port in some electronic atomizing devices, which allows for the continuous replenishment of the liquid matrix. To prevent leakage of the liquid matrix, a separate sealing component is also required at the location of this injection port. As such, existing electronic atomizing devices generally suffer from a large number of sealing components, leading to inconvenient assembly and high manufacturing costs. Utility Model Content

[0030] 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).
[0031] Please see Figure 1 and Figure 2In some embodiments, an electronic atomizing device is provided, comprising a liquid storage unit 1, a control unit 2, a sealing unit 3, and an atomizing unit 4. The liquid storage unit 1 has a liquid storage cavity 10 for storing an atomizing matrix and at least one injection hole 12 communicating with the liquid storage cavity 10. Liquid atomizing matrix can be injected into the liquid storage cavity 10 through the injection hole 12. In some embodiments, the liquid storage unit 1 may further include a liquid storage component 11 disposed within the liquid storage cavity 10, such as a liquid storage cotton, which has good liquid-locking ability. The atomizing unit 4 and the liquid storage unit 1 are located on the same side of the sealing unit 3, and the atomizing unit 4 and the liquid storage unit 1 are in liquid-conducting communication. The atomizing unit 4 is used to atomize the atomizing matrix under the control of the control unit 2. The control unit 2 includes an airflow sensor 21. The airflow sensor 21 generates a corresponding electrical signal in response to changes in airflow, and the control unit 2 controls the atomizing function of the atomizing unit 4 to be turned on and off based on this electrical signal.
[0032] A sealing unit 3 is disposed between the liquid storage unit 1 and the control unit 2 to seal and isolate the liquid storage unit 1 and the control unit 2 from each other, preventing liquid leakage from the liquid storage unit 1 to the control unit 2. The sealing unit 3 includes an integrally formed sealing element 31. That is, the sealing element 31 is an integrally formed independent component. The sealing element 31 includes a first mounting groove 311 and at least one sealing part 312. The airflow sensor 21 is disposed in the first mounting groove 311, and the sealing part 312 is correspondingly disposed with the injection hole 12 to seal the injection hole 12. That is, the first mounting groove 311 for mounting the airflow sensor 21 and the sealing part 312 for sealing the injection hole 12 of the liquid storage unit 1 are disposed on the integrally formed sealing element 31. The same sealing element 31 can perform multiple functions - realizing the installation and sealing of the airflow sensor 21 and the sealing of the injection hole 12 of the liquid storage unit 1. Therefore, it can reduce the number of sealing components inside the electronic atomizing device, facilitate assembly, and reduce manufacturing costs.
[0033] Please see Figures 3 to 7 In some embodiments, the sealing unit 3 further includes a bracket 32, which is connected to the liquid storage unit 1. A sealing element 31 is installed on the side of the bracket 32 facing away from the liquid storage unit 1. The bracket 32 has at least one through hole 320, which corresponds to the injection hole 12. The sealing part 312 passes through the through hole 320 and corresponds to the injection hole 12. Figure 4 , Figure 5 and Figure 7As shown, in some embodiments, there are three injection holes 12, three through holes 320, and three sealing portions 312. The sealing portions 312, through holes 320, and injection holes 12 correspond one-to-one. In some embodiments, the liquid storage unit 1 includes a housing 13, with a liquid storage chamber 10 formed inside the housing 13. The atomizing unit 4 is disposed inside the housing 13, and the injection holes 12 are formed on the surface of the housing 13 facing the sealing unit 3. The bracket 32 and the housing 13 of the liquid storage unit 1 are sealed together to prevent liquid from leaking out from the gap between the bracket 32 and the housing 13.
[0034] Please see Figure 6 In some embodiments, the bracket 32 has a second mounting groove 321 recessed on the side facing away from the liquid storage unit 1, and the seal 31 and the second mounting groove 321 are sealed together. Specifically, the seal 31 and the second mounting groove 321 can be an interference fit. The seal 31 can be an elastic element, such as a silicone element or a rubber element. The size of the seal 31 is slightly larger than the size of the second mounting groove 321. When the seal 31 is inserted into the second mounting groove 321, it is squeezed and deformed, thereby sealing the gap between the seal 31 and the groove wall of the second mounting groove 321, ensuring the sealing performance of the sealing unit 3.
[0035] Please see Figure 2 In some embodiments, the atomizing unit 4 includes an atomizing channel 40. The sealing unit 3 also includes an airflow channel 33, which connects the outside atmosphere and the atomizing channel 40. Thus, under the user's suction force, outside air enters the airflow channel 33 and the atomizing channel 40 sequentially. The first mounting slot 311 is connected to the airflow channel 33, therefore, the airflow sensor 21 in the first mounting slot 311 can sense changes in airflow within the airflow channel 33. Specifically, the atomizing unit 4 also includes an atomizing core 41 and an atomizing tube 42. One end of the atomizing tube 42 is mounted on the bracket 32, and the atomizing tube 42 encloses and forms the atomizing channel 40. The atomizing core 41 is disposed within the atomizing channel 40, and the atomizing core 41 can heat and atomize the atomizing matrix to generate an aerosol when energized. The atomizing core 41 is switched on and off by the control unit 2. The air flowing through the atomizing channel 40 and the aerosol are mixed and then delivered to the user's mouth.
[0036] Please see Figure 6 and Figure 7In some embodiments, the bracket 32 is provided with a first air hole 331, and the sealing member 31 is provided with a second air hole 332. The first air hole 331 is connected to the atomizing channel 40, and the second air hole 332 is connected to the outside atmosphere. The first air hole 331 and the second air hole 332 are connected and together form an airflow channel 33. Thus, under the user's suction force, outside air enters the second air hole 332, the first air hole 331, and the atomizing channel 40 in sequence. Furthermore, the first air hole 331 and the second air hole 332 can be staggered. That is, the projections of the first air hole 331 and the second air hole 332 in the vertical direction do not overlap at least partially. "Vertical direction" can be referred to as Figure 2 The airflow is directed in the VV direction. Therefore, the first vent 331 and the second vent 332 are not directly connected; there is a positional difference between them, allowing for a longer and more tortuous airflow channel 33. That is, in some embodiments, the airflow channel 33 can be tortuously arranged. Simultaneously, since condensate, un-atomized liquid atomizing matrix, and other liquids may be generated within the atomization channel 40, when these liquids drip from the first vent 331, they can be deflected away from the second vent 332, preventing the liquid dripping from the atomization channel 40 from flowing directly from the first vent 331 and the second vent 332 to the control unit 2. Therefore, the mutual misalignment of the first vent 331 and the second vent 332 can also intercept the atomizing matrix dripping from within the atomization channel 40.
[0037] In summary, the same seal 31 can perform three functions: sealing the installation of the airflow sensor 21, sealing the injection hole 12 of the liquid storage unit 1, and providing an airflow channel 33.
[0038] Please see Figures 2 to 5 In some embodiments, the control unit 2 further includes a battery cell 22 and a circuit board 20. The circuit board 20 is located on the side of the seal 31 away from the liquid storage unit 1, and the battery cell 22 is located on the side of the circuit board 20 away from the seal 31. A control circuit is provided on the circuit board 20. The battery cell 22 and the control circuit are electrically connected. An airflow sensor 21 is provided on the circuit board 20. The atomizing core 41 includes a heating element and a liquid guide. The heating element is provided on the liquid guide. The liquid guide can conduct the atomizing matrix in the liquid storage chamber 10 to the heating element, and the heating element can heat and atomize the atomizing matrix to generate an aerosol when energized. The heating element has an electrode lead 411. The battery cell 22 can be electrically connected to the electrode lead 411. The airflow sensor 21 generates a corresponding electrical signal in response to changes in airflow in the airflow channel 33, and the control circuit controls the conduction between the electrode lead 411 and the battery cell 22 based on the electrical signal.
[0039] like Figures 1 to 5As shown, in some embodiments, the electronic atomizing device further includes a housing 5, which forms a receiving cavity in which the liquid storage unit 1, the control unit 2, the sealing unit 3, and the atomizing unit 4 are all disposed. The housing 5 has an air inlet, and the end of the airflow channel 33 away from the atomizing channel 40 is in fluid communication with the air inlet, thereby enabling air intake. Specifically, as... Figures 3 to 5 As shown, in some embodiments, a third air hole 24 is provided on the circuit board 20, and the third air hole 24 is in fluid communication with the second air hole 332 and the air inlet. Thus, under the user's suction force, outside air enters the air inlet, the third air hole 24, the second air hole 332, the first air hole 331 and the atomization channel 40 in sequence.
[0040] Please see Figure 6 and Figure 7 In some embodiments, the sealing unit 3 further includes at least one lead through hole 34, through which the end of the electrode lead 411 away from the atomizing unit 4 passes and is fixed to the side of the sealing unit 3 facing away from the liquid storage unit 1. The portion of the electrode lead 411 fixed to the side of the sealing unit 3 facing away from the liquid storage unit 1 and the battery cell 22 can form an electrical connection. Further, as Figure 6 and Figure 7 As shown, in one embodiment, the lead wire through hole 34 includes a first lead wire hole 341 formed on the bracket 32 and a second lead wire hole 342 formed on the seal 31. The first lead wire hole 341 and the second lead wire hole 342 are connected. The end of the electrode lead wire 411 away from the atomizing unit 4 passes through the first lead wire hole 341 and the second lead wire hole 342 in sequence and is fixed to the side of the sealing unit 3 facing away from the liquid storage unit 1.
[0041] Please see Figure 6 and Figure 7 In some embodiments, the support 32 has an electrode hole 322 recessed on the side facing away from the liquid storage unit 1. The control unit 2 also includes an electrode post 23, which is disposed on the circuit board 20. The electrode post 23 and the airflow sensor 21 are located on the same side of the circuit board 20. The electrode post 23 is embedded in the electrode hole 322. The electrode lead 411 passes through the lead through hole 34, bends, extends into the electrode hole 322, and connects to the electrode post 23. Thus, the battery cell 22, the electrode post 23, and the electrode lead 411 can form an electrical connection to control the atomization function to be turned on and off. Specifically, the number of electrode posts 23 is the same as the number of electrode leads 411, and the electrode posts 23 and electrode leads 411 are connected one-to-one. The number of electrode leads 411 and the number of electrode posts 23 are each at least two. In some embodiments, three electrode leads 411 and three electrode posts 23 can also be provided, wherein two electrode leads 411 are positive and one electrode lead 411 is negative, thereby realizing the switching of atomization power.
[0042] Please see Figure 6 In some embodiments, the sealing member 31 is further recessed on the side facing away from the liquid storage unit 1, and the portion of the electrode lead 411 that bends after passing through the lead through hole 34 is fixed in the lead groove 313. Specifically, the portion of the electrode lead 411 that bends after passing through the lead through hole 34 is embedded in the lead groove 313 for positioning. Therefore, the lead groove 313 can effectively limit the portion of the electrode lead 411 that bends after passing through the lead through hole 34, ensuring the positional stability of the electrode lead 411. Thus, the end of the electrode lead 411 away from the atomizing unit 4 passes through the first lead hole 341 and the second lead hole 342 in sequence, and is fixed in the lead groove 313 and the electrode hole 322 respectively, realizing the electrical conduction and positioning of the electrode lead 411. The number of lead grooves 313 is the same as the number of electrode leads 411, and the electrode leads 411 and lead grooves 313 are fitted together in a one-to-one correspondence.
[0043] In summary, the same seal 31 can perform four functions: sealing the installation of the airflow sensor 21, sealing the injection hole 12 of the liquid storage unit 1, providing the airflow channel 33, and limiting the electrode lead 411.
[0044] 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.
