Description

Technical Field

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

[0002] In the field of atomization technology, ensuring a stable and efficient atomization process is crucial for user experience. The liquid reservoir, as a key component storing the atomizing matrix, has a profound impact on the entire atomization process due to the regulation of its internal air pressure. When a user inhales from the atomizing device, as gas is drawn out of the atomization chamber, the liquid reservoir needs to be ventilated in a timely manner to maintain internal pressure balance and ensure smooth liquid supply. However, current atomizing devices cannot effectively balance the pressure inside and outside the liquid reservoir, leading to unstable atomization effects and even potential issues such as dry burning of the atomizing coil, affecting normal product use and user experience.

[0041] Figure 1 This is a schematic diagram of the atomizing device in some embodiments of this application. Figure 2 yes Figure 1 An explosion diagram of the atomizing device in the embodiment. Figure 3 yes Figure 1 A cross-sectional schematic diagram of the atomizing device in the embodiment.

[0042] This application provides an atomizing device, including a liquid storage chamber 10 and an injection plug 20. The liquid storage chamber 10 contains a liquid storage cavity 13 and an injection channel 1212 that are interconnected. The liquid storage cavity 13 is used to contain the atomizing matrix, and the liquid storage chamber 10 contains an atomizing core 60 for heating the atomizing matrix. The atomizing core 60 is electrically heated to heat the atomizing matrix, causing it to convert into a gaseous state. Specifically, the atomizing core 60 can be a structure with a heating wire wound around a ceramic core, or it can use a novel ceramic heating element, etc. The injection channel 1212 is a tubular structure, which provides a path for the external atomizing matrix to enter the liquid storage cavity 13 when it is necessary to add the atomizing matrix. The injection plug 20 seals the injection channel 1212 and is provided with a pressure regulating structure 50. The pressure regulating structure 50 is used to input and / or output gas to the liquid storage cavity 13 to regulate the internal pressure of the liquid storage cavity 13.

[0043] In the atomizing device provided in this embodiment, the liquid injection channel 1212 is blocked by the liquid injection plug 20, and a pressure regulating structure 50 is provided on the liquid injection plug 20, which can effectively regulate the internal pressure of the liquid storage chamber 13 and ensure the normal use of the product; and the liquid injection plug 20 integrates the functions of sealing the liquid storage chamber 13 and ventilating the liquid storage chamber 13, which simplifies the structure of the atomizing device.

[0044] The atomizing device also includes a power supply component 70, which includes power devices such as batteries and corresponding circuit control modules. These modules control parameters such as voltage and current output to the atomizing core 60 to adjust the heating power of the atomizing core 60, thereby meeting the atomization effect requirements of different users. The power supply component 70 and the liquid storage tank 10 can be configured as an integrated structure or as a separate structure.

[0045] Please see Figures 3 to 5 , Figure 4 yes Figure 1 A schematic diagram of the injection plug in the embodiment. Figure 5 yes Figure 1 A cross-sectional schematic diagram of the injection plug in the embodiment. In some embodiments, the pressure regulating structure 50 includes a one-way check valve 51 and a venting channel 52. The one-way check valve 51 is disposed at one end of the injection plug 20 near the reservoir 13. The one-way check valve 51 can extend from the injection plug 20 into the reservoir 13 to respond to pressure changes in the reservoir 13. The venting channel 52 extends through the interior of the injection plug 20 along the extending direction of the injection channel 1212. The one-way check valve 51 allows external gas to flow unidirectionally into the reservoir 13 through the venting channel 52, while blocking the atomized matrix in the reservoir 13 from flowing out through the venting channel 52.

[0046] In other embodiments, the location of the ventilation channel 52 is not limited to the interior of the injection plug 20. For example, the ventilation channel 52 can be a hollow cylindrical structure, located on the surface of the injection plug 20, as long as it can communicate with the external gas and the storage chamber 13. Similarly, the location of the one-way check valve 51 is not limited to the end of the injection plug 20 closest to the storage chamber 13. For example, the one-way check valve 51 can be located inside the ventilation channel 52, or at the end of the ventilation channel 52 furthest from the storage chamber 13, as long as it can respond to pressure changes in the storage chamber 13 and control the ventilation channel 52 to communicate with or disconnect from the storage chamber 13.

[0047] In this embodiment, the one-way check valve 51 is designed to effectively prevent leakage of the atomizing matrix in the liquid storage chamber 13, ensuring the stability of the atomizing matrix during the atomization process. The ventilation channel 52 allows outside air to enter the liquid storage chamber 13 when needed to regulate and maintain the internal pressure of the liquid storage chamber 13, ensuring the overall safety and reliability of the atomization device.

[0048] Please see Figure 4 and Figure 5 In some embodiments, the one-way check valve 51 includes a first opening / closing portion 511 and a second opening / closing portion 512. The first opening / closing portion 511 and the second opening / closing portion 512 are movably disposed at one end of the injection plug 20 near the liquid storage chamber 13. The first opening / closing portion 511 and the second opening / closing portion 512 form a connecting hole 513, which can selectively connect or disconnect the liquid storage chamber 13 and the ventilation channel 52. When the pressure inside the liquid storage chamber 13 is greater than or equal to the external pressure, the first opening / closing portion 511 and the second opening / closing portion 512 close the connecting hole 513 to disconnect the liquid storage chamber 13 from the ventilation channel 52. When the pressure inside the liquid storage chamber 13 is less than the external pressure, the first opening / closing portion 511 and the second opening / closing portion 512 open the connecting hole 513 to connect the liquid storage chamber 13 with the ventilation channel 52.

[0049] Specifically, the first opening / closing portion 511 and the second opening / closing portion 512 combine to form a duckbill-shaped structure. The first opening / closing portion 511 and the second opening / closing portion 512 are symmetrically arranged on both sides of the ventilation channel 52, extending from the injection plug 20 towards the storage chamber 13 and converging towards each other. The connecting hole 513 is located at the end of the first opening / closing portion 511 and the second opening / closing portion 512 away from the injection plug 20. At least one of the first opening / closing portion 511 and the second opening / closing portion 512 is an elastic body, used for elastic deformation to close or open the connecting hole 513. For example, both the first opening / closing portion 511 and the second opening / closing portion 512 are elastic bodies, and the one-way check valve 51 can be integrally formed with the injection plug 20. Both the injection plug 20 and the one-way check valve 51 are made of easily deformable materials, such as silicone or rubber. When the pressure inside the liquid storage chamber 13 is greater than or equal to the external pressure, the first opening and closing part 511 and the second opening and closing part 512 will be subjected to the gravity of the atomized matrix inside the liquid storage chamber 13 and the pressure of the gas, causing them to move closer to each other, thereby closing the connecting hole 513. Conversely, when the pressure inside the liquid storage chamber 13 is lower than the external pressure, the pressure of the external gas will cause the first opening and closing part 511 and the second opening and closing part 512 to separate from each other, causing the connecting hole 513 to open and allowing gas to flow into the liquid storage chamber 13.

[0050] In other embodiments, the one-way check valve 51 may also be separately disposed from the injection plug 20. The first opening and closing part 511 is an elastic body, while the second opening and closing part 512 is a rigid structure; or, the first opening and closing part 511 is a rigid structure, while the second opening and closing part 512 is an elastic body.

[0051] In other embodiments, the first opening and closing part 511 and the second opening and closing part 512 can be asymmetrical structures, as long as the connecting hole 513 connects the ventilation channel 52 and the liquid storage chamber 13, and the first opening and closing part 511 and / or the second opening and closing part 512 have a closed and open state when elastically deformed, which will not be described in detail here.

[0052] Please see Figure 3 and Figure 5 In some embodiments, the injection plug 20 includes a plug body 23 and multiple sealing rings 21. A venting channel 52 extends through the plug body 23 along its extension direction. A one-way check valve 51 is located at one end of the plug body 23 near the liquid storage chamber 13. The plug body 23 is embedded within the injection channel 1212. The plug body 23 can be a cylinder matching the injection channel 1212, such as a cylindrical or prismatic structure, or a frustum matching the channel, such as a frustum or prismatic structure. The venting channel 52 extends through the plug body 23 of the injection plug 20 and can be a tubular structure with a rectangular, circular, or other irregular cross-section.

[0053] Multiple sealing rings 21 are spaced apart on the outer side of the plug body 23 along its extension direction, with the side of each sealing ring 21 away from the plug body 23 abutting against the injection channel 1212. The sealing rings 21 are designed to ensure a tight seal between the injection plug 20 and the injection channel 1212, preventing leakage of the atomized matrix within the reservoir 13. Furthermore, the number and distribution of the sealing rings 21 can be adjusted according to actual needs to achieve the optimal sealing effect.

[0054] Optionally, the injection plug 20 further includes an air inlet 22, which is located at the end of the plug body 23 away from the liquid storage chamber 13 and abuts against the end of the injection channel 1212 away from the liquid storage chamber 13. The projection of the air inlet 22 onto a first plane overlaps the projection of the injection channel 1212, where the first plane is a reference plane perpendicular to the extending direction of the injection channel 1212. This further seals the end of the injection channel 1212, preventing leakage from the liquid storage chamber 13, and provides insertion feedback during the installation of the injection plug 20.

[0055] Optionally, the air inlet 22 is provided with an air exchange groove 24 communicating with the air exchange channel 52. The air exchange groove 24 extends from the air exchange channel 52 to the outer wall of the air inlet 22, so that gas enters the air exchange channel 52 through the air exchange groove 24. The presence of the air exchange groove 24 further optimizes the ventilation performance of the atomizing device, ensuring the stability and efficiency of the airflow during the atomization process.

[0056] Please see Figure 2 In some embodiments, the liquid storage tank 10 includes a housing 11 and a bottom cover assembly 12. The housing 11 may include an integrally formed suction nozzle 111 and a main body 112. The suction nozzle 111 is for user suction, and the main body 112 has an opening 113 at the end away from the suction nozzle 111. The integrated design of the main body 112 and the suction nozzle 111 eliminates assembly gaps and improves sealing. In other embodiments, the main body 112 and the suction nozzle 111 may be designed as separate parts.

[0057] Please see Figure 6 and Figure 7 , Figure 6 yes Figure 1 A partial explosion diagram of the atomizing device in the embodiment. Figure 7 yes Figure 1The embodiment shows a cross-sectional view of the atomizing device from another section. The bottom cover assembly 12 is installed inside the housing 11 through the opening 113, and the side of the bottom cover assembly 12 facing the opening 113 and the housing 11 enclose the liquid storage cavity 13. The liquid injection channel 1212 is provided on the bottom cover assembly 12. Specifically, the bottom cover assembly 12 includes a cover body 121 and a first support 123, wherein the cover body 121 covers the first support 123, the cover body 121 is located on the side of the bottom cover assembly 12 near the liquid storage cavity 13, the first support 123 is located on the side of the bottom cover assembly 12 away from the liquid storage cavity 13, the liquid injection channel 1212 is provided on the cover body 121 and extends from the side near the liquid storage cavity 13 toward the first support 123, and the liquid injection plug 20 is inserted into the liquid injection channel 1212 and abuts against the end of the liquid injection channel 1212 away from the liquid storage cavity 13.

[0058] Furthermore, the bottom cover assembly 12 also includes a base 124 disposed on the side of the first support 123 away from the cover body 121. The base 124 and the first support 123 enclose an air chamber 14. An air inlet channel 1241 is provided on the base 124 to connect the air chamber 14 with external gas. The air chamber 14 can be selectively connected to or isolated from the liquid storage chamber 13 through a pressure regulating structure 50. The base 124 is fixedly connected to the housing 11, specifically by snap-fit, bolt connection, etc., which is not specifically limited here.

[0059] In this embodiment, the cover 121 is first placed over the opening 113 of the housing 11 to form a liquid storage cavity 13. After injecting the atomized matrix into the liquid storage cavity 13 through the injection channel 1212, the injection plug 20 is inserted into the injection channel 1212. Then, the first support 123 and the base 124 are sequentially installed on the side of the cover 121 away from the liquid storage cavity 13. The side of the cover 121 away from the liquid storage cavity 13 can abut against the first support 123, and the side of the first support 123 away from the cover 121 abuts against the base 124. The fixed connection between the cover 121 and the housing 11 restricts the movement of the cover 121 and the first support 123.

[0060] Please see Figure 6In some embodiments, the bottom cover assembly 12 further includes a sealing element 122, which is disposed between the cover body 121 and the first bracket 123 to seal the gap between the housing 11 and the cover body 121, ensuring the sealing performance of the liquid storage chamber 13. The sealing element 122 has a mounting groove 1221 on the side facing the cover body 121, and the cover body 121 has a liquid inlet hole 1211. The mounting groove 1221 is in fluid communication with the liquid storage chamber 13 through the liquid inlet hole 1211. The atomizing core 60 is disposed within the mounting groove 1221. The atomizing core 60 includes an atomizing channel 61 and a liquid guiding component 62. The atomizing channel 61 has through holes on its periphery. The liquid guiding component 62 covers the periphery of the atomizing channel 61 and can be made of absorbent material such as cotton wick. The liquid guiding component 62 covers the liquid inlet hole 1211 and the through holes on the periphery of the atomizing channel 61 to allow the liquid guiding component 62 to absorb the atomizing matrix in the liquid storage chamber 13 through the liquid inlet hole 1211 and guide the atomizing matrix into the atomizing channel 61. An air inlet hole 1234 is provided on the sealing component 122. Specifically, the air inlet hole 1234 can be located at the bottom of the mounting groove 1221. The atomizing channel 61 communicates with the air chamber 14 through the air inlet hole 1234. The size and number of air inlets 1234 can be adjusted according to actual needs to ensure sufficient and stable air supply. During the suction process, air enters the air chamber 14 through the air inlet channel 1241. The gas in the air chamber 14 enters the liquid storage chamber 13 through the pressure regulating structure 50 to balance the internal and external pressure of the liquid storage chamber 13. On the other hand, it enters the atomization channel 61 through the air inlet 1234 to mix with the aerosol, thus meeting the user's air supply needs during suction.

[0061] In this embodiment, the atomizing core 60 is installed outside the liquid storage chamber 13 and arranged side by side with the liquid injection channel 1212, thereby effectively utilizing the lateral space of the atomizing device and avoiding the atomizing core 60 occupying the internal space of the liquid storage chamber 13.

[0062] In other embodiments, the atomizing core 60 may be disposed inside the liquid storage chamber 13. During assembly, the atomizing core 60 may be installed inside the housing 11 through the opening 113 of the housing 11, and then the cover 121 may be placed over the opening 113 of the housing 11 to form the liquid storage chamber 13.

[0063] Please combine Figure 2 and Figure 7 In some embodiments, the atomizing device further includes a liquid suction element 30 disposed within the air chamber 14. At least a portion of the projection of the liquid suction element 30 onto the first plane covers the projection of the injection channel 1212 onto the first plane. The liquid suction element 30 is made of a porous material such as a sponge and can adhere tightly to the end of the injection plug 20 to absorb any leaked atomizing matrix. Combined with the aforementioned embodiment where the ventilation groove 24 extends to the outer wall of the injection plug 20, even if the liquid suction element 30 obstructs the ventilation channel 52, gas flow can still be maintained through the ventilation groove 24.

[0064] Please see Figure 8 , Figure 8 yes Figure 1 A partial structural diagram of the atomizing device in the embodiment is shown. Optionally, the first support 123 includes a fixing part 1231 and a limiting part 1232 extending from the fixing part 1231 away from the seal 122. The liquid suction member 30 abuts against the limiting part 1232, and the limiting part 1232 has a notch 1233 connecting the pressure regulating structure 50 and the air chamber 14. When the liquid suction member 30 is affected by pressure changes from the atomizing matrix or the air chamber 14, it can deform appropriately according to the constraint of the limiting part 1232. This deformation not only avoids the risk of the liquid suction member 30 over-expanding and blocking the port of the air exchange groove 24, but also ensures the unobstructed gas flow path. The design of the notch 1233 can further maintain the gas exchange between the air chamber 14 and the pressure regulating structure 50, thereby ensuring the overall performance and stability of the atomizing device.

[0065] Please combine Figure 2 and Figure 3 In some embodiments, a circuit board 40 is also included. The circuit board 40 is located on the side of the liquid suction member 30 away from the liquid injection channel 1212, and its projection on the first plane does not overlap with the projection of the liquid injection channel 1212 on the first plane, preventing the circuit board 40 from being contaminated by leaked liquid. The circuit board 40 may integrate an airflow sensor. The liquid suction member 30 has a liquid suction hole, and the airflow sensor is exposed to the air chamber 14 through a clearance hole on the liquid suction member 30. The airflow sensor adjusts the power supply according to the user's suction action: heating is activated when inhaling, and power is deactivated after a delay after inhalation stops.
