Description

Technical Field

[0001] This invention relates to the field of atomizer technology, specifically to electronic atomizers. Background Technology

[0002] An electronic atomizer is an atomizer powered by a rechargeable lithium polymer battery that produces "vapor" for the user to inhale by heating a liquid matrix in a tank. It has a similar appearance, smoke, taste, and feel to cigarettes.

[0003] As people become increasingly health-conscious, they are beginning to realize the harmful effects of tobacco. Because liquid bases do not contain tar, the harm to the human body from vaporized liquid bases is reduced. Therefore, electronic atomizers are widely used and are gradually replacing cigarettes.

[0004] Existing e-cigarettes produce a significant amount of condensation during operation, requiring the addition of absorbent cotton to prevent it from flowing onto the battery and causing a short circuit. However, adding absorbent cotton complicates the e-cigarette's structure, and even with absorbent cotton, condensation can still flow onto the battery. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings and deficiencies of the prior art by providing an electronic atomizer that eliminates the need for absorbent cotton. The condensate is adsorbed onto the first groove of the sealing gasket, which has the advantage of preventing condensate from entering the battery and causing a short circuit, and the adsorbed condensate can also cool the device again.

[0006] The sealing gasket effectively separates the atomizing chamber and the pressure balancing chamber. The condensate from the atomizing chamber is absorbed within the groove of the sealing gasket and will not flow into the pressure balancing chamber or the battery. If it flows into the pressure balancing chamber, it will cause the pressure balancing device to malfunction; if it flows into the battery, it will cause a short circuit.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is: an electronic atomizer, comprising:

[0008] The outer shell has a liquid storage chamber for storing liquid matrix inside. One end of the outer shell is provided with a smoke port and the other end is provided with an air inlet.

[0009] An atomizing component, disposed within the housing, is used to heat and atomize the liquid matrix;

[0010] A sealing gasket is disposed inside the housing, located below the atomizing component, and is used to seal the PCBA assembly;

[0011] The PCBA assembly is disposed within the housing and mounted on the underside of the sealing gasket; and

[0012] The battery is disposed inside the housing, located below the PCBA assembly, and electrically connected to the PCBA assembly;

[0013] The sealing gasket has an atomizing channel in the middle, with its upper end connected to the middle of the atomizing component and its lower end connected to the air inlet of the outer shell; the atomizing channel of the sealing gasket and the atomizing component form an atomizing chamber.

[0014] Both sides of the sealing gasket are provided with an air pressure balance channel: the upper end of which is connected to both sides of the atomizing component and sealed by the atomizing component, and the lower end of which is connected to the air inlet of the atomizing channel; the air pressure balance channel of the sealing gasket and the atomizing component form an air pressure balance chamber.

[0015] The top of the sealing gasket is provided with a first groove for adsorbing condensate.

[0016] The present invention further provides that the atomizing component has connecting pins on both sides of its bottom end, and the sealing gasket has connecting grooves on both sides of its top end for the connecting pins to be inserted and assembled.

[0017] The present invention further provides that the top of the sealing gasket is provided with an upwardly protruding extension plate located between the two connecting grooves, and the extension plate is provided with a longitudinal second groove; the lower end of the second groove communicates with the first groove.

[0018] The present invention further provides that there are multiple first grooves, which are distributed around the periphery of the atomizing channel.

[0019] In a further embodiment of the present invention, the first groove is elongated.

[0020] In a further embodiment of the present invention, the sealing gasket is provided with several raised ribs around its periphery.

[0021] The present invention further provides that the PCBA assembly includes: a PCBA board, a microphone fixedly disposed on one side of the PCBA board, and an electrode connector disposed on the upper end of the PCBA board and electrically connected to the PCBA board; the electrode connector has an airflow hole with its upper end communicating with the atomization channel of the sealing gasket and its lower end communicating with the air inlet of the outer shell.

[0022] The present invention further includes a microphone silicone pad mounted on the PCBA assembly; a microphone air intake is formed between the microphone silicone pad, the microphone, and the PCBA board; the microphone air intake is connected to the microphone's activation position at the position with the smallest cross-section.

[0023] The present invention further provides that the sealing gasket has an electrode post through hole for the electrode of the electrode connector to pass through.

[0024] The present invention further includes a foam disposed inside the outer casing and at the lower end of the battery.

[0025] After adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0026] In this invention, a sealing gasket separates the atomizing chamber and the pressure balancing chamber. The condensate generated during atomization is absorbed by the first groove of the sealing gasket. This absorbed condensate further cools the heating surface of the atomizing component. Because the condensate is absorbed in the first groove of the sealing gasket, it will not flow into the pressure balancing chamber and block the pressure balancing channel, nor will it flow back into the battery from the atomizing channel and cause a short circuit, thus providing excellent isolation.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings.

[0039] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.

[0040] This embodiment relates to an electronic atomizer; please refer to [link / reference]. Figures 1-6 It includes: outer shell, atomizing component 3, sealing gasket 4, PCBA component 5, battery 6, microphone 52, silicone and foam 8.

[0041] Among them, such as Figure 1 , Figure 3 and Figure 7 As shown, the outer shell includes an upper shell 1 and a lower shell 2. The upper shell 1 has a liquid storage chamber a for storing the liquid matrix. The top of the upper shell 1 is configured as the end where the user inhales the aerosol and is provided with a smoke inlet b. The bottom of the lower shell 2 is provided with an air inlet c.

[0042] Specifically, such as Figure 2 , Figure 4 and Figure 7 As shown, the atomizing component 3 is disposed within the upper shell 1 and is used to heat and atomize the liquid matrix. The sealing gasket 4 is disposed within the lower shell 2, located below the atomizing component 3, and is used to seal the PCBA component 5. The PCBA component 5 is disposed within the lower shell 2 and is mounted below the sealing gasket 4. The battery 6 is disposed within the lower shell 2, located below the PCBA component 5, and is electrically connected to the PCBA component 5. A microphone silicone 7 is mounted on the PCBA component 5, forming a microphone air inlet d between the microphone silicone 7, the microphone 52, and the PCBA board 51. Foam 8 is disposed within the lower shell 2 and located below the battery 6. The foam 8 serves both as shock absorber and as a absorber to prevent condensation from accidentally flowing back into the battery compartment 6.

[0043] During assembly, the battery 6 is soldered onto the PCBA assembly 5, and the foam 8 is attached to the battery 6. The microphone silicone 7 is installed onto the PCBA assembly 5, and then the sealing gasket 4 is installed. The entire assembly is then installed into the lower shell 2. The atomizing liquid matrix is ​​injected into the liquid storage chamber a of the upper shell 1, and then the atomizing assembly 3 is installed. Finally, the upper shell 1 is assembled with the lower shell 2.

[0044] Please refer to Figure 5 and Figure 8 The sealing gasket 4 has an atomizing channel e in its middle, with its upper end connected to the middle of the atomizing component 3 and its lower end connected to the air inlet c of the outer shell; the atomizing channel e of the sealing gasket 4 and the atomizing component 3 form an atomizing chamber f. Both sides of the sealing gasket 4 have pressure balancing channels g, with their upper ends connected to both sides of the atomizing component 3 and their lower ends connected to the air inlet of the atomizing channel e. The pressure balancing channels g of the sealing gasket 4 and the atomizing component 3 form a pressure balancing chamber h. Furthermore, the top of the sealing gasket 4 has a first groove 41 for absorbing condensate.

[0045] For details regarding the internal airflow of this electronic atomizer, please refer to [link / reference]. Figure 2 , Figure 4 and Figure 5 The main airflow i enters from the air inlet c of the lower shell 2, and enters the sealing gasket 4 through the air intake channel of the microphone 52. The sealing gasket 4 divides the main airflow i into two streams: one is the atomizing airflow j, which enters the atomizing chamber f through the atomizing channel e of the sealing gasket 4; the other is the pressure balancing airflow k, which enters the pressure balancing chamber h through the pressure balancing channel g of the sealing gasket 4.

[0046] The sealing gasket 4 separates the atomizing chamber f and the pressure balancing chamber h. The condensate generated during atomization is absorbed by the first groove 41 of the sealing gasket 4. This condensate in the first groove 41 further cools the heating surface of the atomizing component 3. Because the condensate is absorbed on the first groove 41 of the sealing gasket 4, it will not flow into the pressure balancing chamber h and block the pressure balancing channel g, nor will it flow back into the battery 6 from the atomizing channel e, causing a short circuit, thus providing excellent isolation.

[0047] In addition, the sealing gasket 4 also serves to fix and seal the PCBA assembly 5, simplifying the structure and saving costs while ensuring functionality, thus increasing the competitiveness of the product.

[0048] Please refer to Figure 8 The atomizing component 3 has connecting pins 31 on both sides of its bottom end, and the sealing gasket 4 has connecting grooves 42 on both sides of its top end for the connecting pins 31 to be inserted and assembled. This makes the sealing gasket 4 and the atomizing component 3 more stable after assembly.

[0049] Please refer to Figure 8The sealing gasket 4 has an upwardly protruding extension plate 43 located between two connecting grooves 42 at its top. The extension plate 43 has a longitudinal second groove 44. The lower end of the second groove 44 communicates with the first groove 41. Part of the condensate generated during atomization is adsorbed onto the extension plate 43 and flows along the second groove 44 into the first groove 41. Preferably, there are multiple first grooves 41 distributed around the periphery of the atomization channel e. In this embodiment, the first groove 41 is elongated; in other embodiments, it can have other shapes. In this embodiment, the sealing gasket 4 has several raised ribs 45 around its periphery. Therefore, after the sealing gasket 4 is assembled inside the lower shell 2, it can better seal the PCBA assembly 5.

[0050] Please refer to Figures 5-7 and Figure 9 The PCBA assembly 5 includes: a PCBA board 51, a microphone 52 fixedly disposed on one side of the PCBA board 51, and an electrode connector 53 disposed on the upper end of the PCBA board 51 and electrically connected to the PCBA board 51. The electrode connector 53 has an air passage 54, the upper end of which communicates with the atomization channel e of the sealing gasket 4, and the lower end of which communicates with the air inlet c of the lower shell 2.

[0051] Please refer to Figures 5-7 The PCBA assembly 5 is equipped with microphone silicone 7. Microphone silicone 7, microphone 52, and PCBA board 51 form a microphone air intake duct d. The microphone air intake duct d is connected to the microphone 52 at its minimum cross-sectional area. Here, the airflow velocity is high, resulting in low pressure. One end of the microphone 52 is connected to the atmosphere, and the other end is connected to the microphone silicone duct. This large pressure difference results in high starting sensitivity of the microphone 52.

[0052] Please refer to Figure 8 The sealing gasket 4 has an electrode post through-hole 46 for the electrode of the electrode connector 53 to pass through. Thus, the PCBA assembly 5 can pass through the sealing gasket 4 and be electrically connected to the atomizing assembly 3.

[0053] The working principle of this invention is roughly as follows: The sealing gasket 4 separates the atomizing chamber f and the pressure balancing chamber h. The condensate generated during atomization is absorbed by the first groove 41 of the sealing gasket 4. The condensate absorbed in the first groove 41 further cools the heating surface of the atomizing component 3. Because the condensate is absorbed on the first groove 41 of the sealing gasket 4, it will not flow into the pressure balancing chamber h and block the pressure balancing channel g, nor will it flow back into the battery 6 from the atomizing channel e, causing a short circuit, thus providing excellent isolation. Furthermore, the sealing gasket 4 also serves to fix and seal the PCBA component 5, simplifying the structure and saving costs while ensuring functionality, thereby increasing the product's competitiveness.

[0054] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be covered within the scope of the claims of the present invention.
