Description

Technical Field

[0001] This application relates to the field of atomizer technology, and more particularly to an electronic atomizing device. Background Technology

[0002] An electronic atomizing device is a product that atomizes an aerosol-generating base liquid into an aerosol. When the user inhales, the aerosol flows with the airflow generated by the user's inhalation and exits the electronic atomizing device. The atomizing component includes a heating component. An oil-guiding cotton in the heating component supplies the aerosol-generating base liquid to a heating mesh in the heating component. The heating mesh heats the aerosol-generating base liquid supplied by the oil-guiding cotton, generating an aerosol. However, uneven oil supply from the oil-guiding cotton can easily cause problems such as dry burning of the heating component and oil splattering.

[0003] In related technologies, to solve the problem of uneven oil supply, an atomizing assembly is composed of a room-temperature atomizing element and a heating element. The room-temperature atomizing element first atomizes the aerosol-generating base liquid into small aerosol particles, allowing these particles to evenly contact the heating element and preventing dry burning or oil splattering. However, the liquid storage space within the improved electronic atomizing device is compressed. Utility Model Content

[0007] The beneficial effects of the electronic atomizing device provided in this application are as follows: Since the aerosol generating base liquid in the first storage chamber can flow to the second storage chamber by gravity, the aerosol in the first storage chamber can be replenished to the second storage chamber. Since the heating chamber is installed in the first storage chamber, the first storage chamber is arranged around the heating chamber.

[0041] An electronic atomizing device is a product that atomizes an aerosol-generating base liquid into an aerosol. When the user inhales, the aerosol flows with the airflow generated by the user's inhalation and exits the electronic atomizing device. The atomizing component includes a heating component. An oil-guiding cotton in the heating component supplies the aerosol-generating base liquid to a heating mesh in the heating component. The heating mesh heats the aerosol-generating base liquid supplied by the oil-guiding cotton, generating an aerosol. However, uneven oil supply from the oil-guiding cotton can easily cause problems such as dry burning of the heating component and oil splattering.

[0042] In related technologies, to solve the problem of uneven oil supply, an atomizing assembly is composed of a room-temperature atomizing element and a heating element. The room-temperature atomizing element first atomizes the aerosol-generating base liquid into small aerosol particles, allowing these particles to evenly contact the heating element and preventing dry burning or oil splattering. However, the liquid storage space within the improved electronic atomizing device is compressed.

[0043] In view of the above problems, this application provides an electronic atomizing device, which aims to increase the liquid storage space of the electronic atomizing device.

[0044] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0045] Please refer to Figures 1 to 3 This application provides an electronic atomizing device, including a first chamber 1, a second chamber 2, an atomizing component 3, and a heating component 4.

[0046] The first chamber 1 has a first storage chamber 11 for storing aerosol generating base liquid and a heating chamber 12 passing through the first storage chamber 11; the second chamber 2 has a second storage chamber 21 communicating with the first storage chamber 11, and the second chamber 2 is stacked with the first chamber 1 and surrounds the first chamber 1 to form an atomizing chamber 5 communicating with the heating chamber 12; at least a portion of the atomizing component 3 is housed in the atomizing chamber 5 and communicates with the second storage chamber 21, and the atomizing component 3 is used to atomize the aerosol generating base liquid entering the atomizing component 3 at room temperature to generate room temperature aerosol in the atomizing chamber 5; the heating component 4 is housed in the heating chamber 12 and is used to heat the aerosol passing through the heating chamber 12; wherein, the aerosol generating base liquid in the first storage chamber 11 can flow by gravity into the second storage chamber 21.

[0047] Please refer to Figure 3 The electronic atomizing device of this application embodiment is provided with an air inlet channel and a suction channel 1331. The air inlet channel is connected to the outside of the electronic atomizing device and the atomizing chamber 5, respectively, and the suction channel 1331 is connected to the outside of the electronic atomizing device and the heating chamber 12, respectively. When the electronic atomizing device is inhaled, the airflow direction is: air inlet channel → atomizing chamber 5 → heating chamber 12 → suction channel 1331.

[0048] It should be noted that the electronic atomizing device of this application embodiment also includes a control component (not shown in the figure), which is electrically connected to both the atomizing component 3 and the heating component 4. When inhaling the electronic atomizing device of this application embodiment, the airflow passes through the microphone on the control component, which drives the atomizing component 3 and the heating component 4 to operate. The atomizing component 3 operates to atomize the aerosol generating base liquid entering the atomizing component 3 at room temperature to generate room temperature aerosol in the atomizing chamber 5. Under the action of suction, the airflow carries the room temperature aerosol in the atomizing chamber 5 into the heating chamber 12. The heating component 4 operates to heat the aerosol entering the heating chamber 12, thereby stimulating the aroma of the aerosol, increasing the temperature of the aerosol flowing out of the heating chamber 12, and improving the taste of the aerosol flowing out of the heating chamber 12. Under the action of suction, the heated aerosol flows into the suction channel 1331 and flows out of the electronic atomizing device through the suction channel 1331.

[0049] It should be noted that the atomizing component 3 is used to atomize the aerosol generating base liquid entering the atomizing component 3 at room temperature to generate room temperature aerosol in the atomizing chamber 5. This means that the atomizing component 3 converts the aerosol generating base liquid into fine droplets through physical or mechanical means, that is, converts the aerosol generating base liquid into aerosol. Specifically, the atomizing component 3 can atomize the aerosol generating base liquid through atomization methods such as ultrasonic atomization or micro-mesh atomization.

[0050] It should be noted that the heating component 4 is used to heat the aerosol passing through the heating chamber 12. This means that after the control component supplies power to the heating component 4, the temperature of the heating component 4 increases. When the aerosol flows through the heating chamber 12, the aerosol exchanges heat with the heating component 4, causing the temperature of the aerosol to rise. The heating component 4 also includes a heating mesh and heating wires. It can be understood that room temperature aerosol can be considered as smoke composed of numerous tiny liquid droplets, with a diameter of approximately 1µm-10µm. When the room temperature aerosol passes through the heating component 3, the smaller droplets vaporize directly at high temperature, while the larger droplets partially vaporize. In other words, the aerosol passing through the heating component 3 undergoes high-temperature heating, which can release the aroma of the aerosol, while maintaining the liquid content of the aerosol, resulting in a mild and smooth inhalation experience for the user. In this embodiment, the heating component 4 heats the room-temperature aerosol passing through the heating chamber 12, which can further atomize the aerosol to make it more gentle and mild. On the other hand, it can appropriately increase the inlet temperature of the aerosol to stimulate the aroma of the aerosol and enhance its taste, thereby improving the user's inhalation experience.

[0051] As the atomizing component 3 continues to operate, the aerosol generating base liquid in the second storage chamber 21 will be consumed. Since the aerosol generating base liquid in the first storage chamber 11 can flow into the second storage chamber 21 by gravity, the aerosol in the first storage chamber 11 can be replenished to the second storage chamber 21. Furthermore, in the electronic atomizing device of this embodiment, the heating chamber 12 is disposed in the first storage chamber 11, so the first storage chamber 11 is arranged around the heating chamber 12. By making reasonable use of the space around the heating chamber 12, the space for storing the aerosol generating base liquid can be increased, thereby increasing the liquid storage space of the electronic atomizing device.

[0052] Please refer to Figure 1 , Figure 3 and Figure 4 In some embodiments, the first chamber 1 includes a first oil cup 13, a first sealing member 14, and a venting member 15. The first oil cup 13 includes a cup wall 131 and a top cover 132 connected to one end of the cup wall 131. The top cover 132 has a first mating hole 1321. A portion of the first sealing member 14 is inserted into the end of the first oil cup 13 away from the top cover 132. The first sealing member 14 has a second mating hole 141. The venting member 15 is housed in the first oil cup 13 and surrounds it to form a heating chamber 12. One end of the venting member 15 communicates with the first mating hole 1321, and the other end of the venting member 15 communicates with the second mating hole 141. The outer wall of the venting member 15, the first oil cup 13, and the first sealing member 14 surround to form a first liquid storage chamber 11.

[0053] In the above embodiment, after aligning the air guide 15 with the first mating hole 1321 and placing it inside the first oil cup 13, the first sealing member 14 is inserted into the end of the first oil cup 13 away from the top cover 132, thus completing the installation of the first chamber 1. Disassembling the first chamber 1 into the independently set first oil cup 13, first sealing member 14, and air guide 15 facilitates the assembly and maintenance of the first chamber 1.

[0054] In the above embodiment, when the electronic atomizing device is drawn in, the airflow direction is: air inlet channel → atomizing chamber 5 → second docking hole 141 on the first sealing member 14 → air guide member 15 → first docking hole 1321 on the top cover 132 → suction channel 1331.

[0055] Please refer to Figure 4 The top cover 132 protrudes from the surface of the first liquid storage chamber 11 to form a docking post 1322, and the docking post 1322 is provided with a first docking hole 1321.

[0056] Please refer to Figure 3 and Figure 4 In some embodiments, the air guide 15 is inserted into the docking post 1322, or the air guide 15 is sleeved on the periphery of the docking post 1322.

[0057] Please refer to Figure 4 In some embodiments, the first chamber 1 further includes a sealing ring 16 located between the docking post 1322 and the air guide 15 to improve the sealing performance of the first liquid storage chamber 11.

[0058] Please refer to Figure 4 In some embodiments, the second mating hole 141 includes a coaxially arranged insertion hole 1411 and a communicating hole 1412. One end of the communicating hole 1412 communicates with the insertion hole 1411, and the other end of the insertion hole 1411 communicates with the atomizing chamber 5. The diameter of the communicating hole 1412 is smaller than that of the insertion hole 1411, so that a support surface is formed between the inner wall of the communicating hole 1412 and the inner wall of the insertion hole 1411. The support surface can support the air guide 15 so that the air guide 15 can be received and fixed in the first liquid storage chamber 11; and the support surface can support the heating assembly 4 so that the heating assembly 4 can be received and fixed in the heating chamber 12.

[0059] In the above embodiment, the end of the air guide 15 away from the first docking hole 1321 is inserted into the insertion hole 1411.

[0060] In some embodiments, the heating assembly 4 includes a heating element housed within the air guide 15.

[0061] In the above embodiments, the heating element is attached to the inner wall of the air guide 15, or the heating element covers the connecting hole 1412.

[0062] In the above embodiment, when the electronic atomizing device is inhaled, the airflow direction is: air inlet channel → atomizing chamber 5 → connecting hole 1412 → insertion hole 1411 → air guide 15 → first docking hole 1321 on top cover 132 → suction channel 1331.

[0063] Please refer to Figure 4 In some embodiments, the first oil cup 13 further includes a suction nozzle 133 disposed on the top cover 132, a suction channel 1331 disposed on the suction nozzle 133, and the suction channel 1331 communicating with the first docking hole 1321. Optionally, the suction nozzle 133, the top cover 132, and the cup wall 131 are integrally formed.

[0064] In some embodiments, the cup wall 131 is at least partially a light-transmitting structure.

[0065] With the above-described design, the light-transmitting structure facilitates observation of the structure within the first liquid storage chamber 11. This allows for observation of the aerosol-generating base liquid's state (liquid level, cleanliness, etc.) within the chamber, enabling timely replenishment or replacement of oxidized or contaminated aerosol-generating base liquid. Furthermore, when cleaning the first oil cup 13, the light-transmitting structure makes it easy to see whether there is any oil residue inside, facilitating the cleaning process.

[0066] Please refer to Figure 5 In some embodiments, the top cover 132 is provided with an injection hole 1323 that communicates with the first liquid storage chamber 11; the first chamber 1 also includes a sealing plug 17, which is filled in the injection hole 1323.

[0067] In the above embodiment, when replenishing the aerosol generating base liquid into the first liquid storage chamber 11, the sealing plug 17 is removed from the injection hole 1323, then new aerosol generating base liquid is added to the first liquid storage chamber 11, and then the sealing plug 17 is sealed back into the injection hole 1323. This arrangement facilitates the replenishment of the aerosol generating base liquid into the first liquid storage chamber 11.

[0068] Please refer to Figure 1 , Figure 3 and Figure 4 In some embodiments, the second chamber 2 includes a second oil cup 22 and a second sealing member 23. The second oil cup 22 includes a base plate 221 and a first sidewall 222 and a second sidewall 223 extending vertically from the edge of the base plate 221 in opposite directions. The end of the first sidewall 222 away from the base plate 221 is fitted onto the first sealing member 14 and connects to the cup wall 131. The second sealing member 23 is inserted into the end of the second sidewall 223 away from the base plate 221 and together with the second oil cup 22, forms a second liquid storage cavity 21. The base plate 221 and the first sealing member 14 together form an atomizing cavity 5.

[0069] In the above embodiment, the end of the first sidewall 222 away from the substrate 221 is fitted onto the first sealing member 14, and then the second sealing member 23 is inserted into the end of the second sidewall 223 away from the substrate 221 to complete the installation of the second compartment 2. The second compartment 2 is disassembled into the independently set second oil cup 22 and second sealing member 23, which facilitates the assembly and maintenance of the second compartment 2.

[0070] Please refer to Figure 4 and Figure 4 In the above embodiment, the substrate 221 is provided with an atomizing groove 2211 facing the first sealing member 14, and the first sealing member 14 covers the opening of the atomizing groove 2211, so that the substrate 221 and the first sealing member 14 can be arranged to form an atomizing cavity 5.

[0071] Please refer to Figure 5 and Figure 6 In some embodiments, the first sealing member 14 is provided with a first through hole 142 communicating with the first liquid storage chamber 11, and the substrate 221 is provided with a second through hole 2212 communicating with the second liquid storage chamber 21. The second through hole 2212 corresponds to and communicates with the first through hole 142. The first liquid storage chamber 11 and the second liquid storage chamber 21 are interconnected through the first through hole 142 and the second through hole 2212, so that the aerosol generating base liquid in the first liquid storage chamber 11 can flow into the second liquid storage chamber 21.

[0072] Please refer to Figure 5 and Figure 6 In some embodiments, the substrate 221 has a protrusion on the surface facing the first seal 14 to form a plug post 2213, and the plug post 2213 has a second through hole 2212. The plug post 2213 is inserted into the first through hole 142 and is press-fitted with the first through hole 142 so that the second through hole 2212 communicates with the first through hole 142.

[0073] In the above embodiment, the insertion of the plug post 2213 into the first through hole 142 helps to fix the first seal 14, thereby fixing the relative position of the first seal 14 and the substrate 221, thereby preventing the first through hole 142 and the second through hole 2212 from being misaligned, so that the first liquid storage chamber 11 and the second liquid storage chamber 21 can remain in a connected state.

[0074] Please refer to Figure 4 In some embodiments, the substrate 221 is provided with an oil guide hole 2214 communicating with the atomizing chamber 5, and at least part of the structure of the atomizing component 3 extends into the second liquid storage chamber 21 through the oil guide hole 2214.

[0075] In the above embodiment, at least a portion of the structure of the atomizing component 3 extends into the second liquid storage chamber 21 through the oil guide hole 2214, which not only allows the atomizing component 3 to communicate with the second liquid storage chamber 21 through the oil guide hole 2214, but also allows a portion of the structure of the atomizing component 3 to be confined within the oil guide hole 2214, thereby defining the position of the atomizing component 3.

[0076] Please refer to Figure 4 In the above embodiment, the surface of the substrate 221 facing the second seal 23 protrudes to form an oil guide column 2215, and the oil guide column 2215 is provided with an oil guide hole 2214. The oil guide column 2215 is inserted into the second liquid storage cavity 21 and is spaced apart from the second seal 23 so that the second liquid storage cavity 21 can communicate with the oil guide hole 2214.

[0077] Please refer to Figure 3 and Figure 4 In some embodiments, the atomizing component 3 includes a liquid guiding component 31 and a room temperature atomizing component 32. The room temperature atomizing component 32 is housed in the atomizing chamber 5. One end of the liquid guiding component 31 is connected to the room temperature atomizing component 32, and the other end of the liquid guiding component 31 away from the room temperature atomizing component 32 is inserted into the oil guiding hole 2214. The room temperature atomizing component 32 is in communication with the atomizing chamber 5.

[0078] In the above embodiment, the liquid guiding component 31 can absorb the aerosol generating base liquid in the second liquid storage chamber 21 and transport the aerosol generating base liquid to the room temperature atomizing component 32. The room temperature atomizing component 32 converts the aerosol generating base liquid in the liquid guiding component 31 into fine droplets, that is, the room temperature atomizing component 32 atomizes the aerosol generating base liquid in the liquid guiding component 31 into room temperature aerosol.

[0079] In the above embodiment, the liquid guiding component 31 is made of microporous material. The aerosol generating base liquid is transported to the room temperature atomizing component 32 through the micropores on the liquid guiding component 31 via the capillary effect, so that the aerosol generating base liquid can adhere to the room temperature atomizing component 32.

[0080] In the above embodiment, the room-temperature atomizing element 32 can be an ultrasonic oscillator. Optionally, the ultrasonic oscillator includes a transducer and a microporous atomizing plate. The microporous atomizing plate is disposed on the end face of the liquid guiding element 31, so that the aerosol generating base liquid on the end face of the liquid guiding element 31 can adhere to the micropores of the microporous atomizing plate. The transducer is used to convert electrical energy into mechanical vibration energy, causing the microporous atomizing plate to vibrate at high frequency, triggering high-frequency fluctuations on the surface of the aerosol generating base liquid attached to the micropores. Due to the vibration, the surface of the aerosol generating base liquid attached to the micropores of the microporous atomizing plate forms capillary waves (surface waves with extremely short wavelengths). The aerosol generating base liquid at the wave crest is "torn" by surface tension to form fine droplets, thus atomizing the aerosol generating base liquid to generate room-temperature aerosol. The micropores on the microporous atomizing plate are connected to the atomization chamber 5.

[0081] In the above embodiment, the room-temperature atomizing element 32 can be a high-pressure nozzle, which includes a specific structure such as a nozzle or micro-orifice and a pump body. The pump body pressurizes the aerosol-generating base liquid in the liquid guiding element 31 through mechanical force and then sprays it out through the specific structure such as the nozzle or micro-orifice to form fine droplets, thereby atomizing the aerosol-generating base liquid to generate room-temperature aerosol. The specific structure such as the nozzle or micro-orifice is connected to the atomization chamber 5.

[0082] Please refer to Figure 3 and Figure 4 In some embodiments, the second chamber 2 further includes an air guide column 24, which penetrates the substrate 221 and the second sealing member 23. The air guide column 24 is provided with an air inlet 241, which connects to the outside and the atomizing chamber 5.

[0083] In the above embodiment, the air inlet 241 in the air guide column 24 forms at least a partial air intake channel, and the end of the air guide column 24 that penetrates through the substrate 221 is connected to the atomizing groove 2211 on the substrate 221, so that the air intake channel can be connected to the atomizing chamber 5.

[0084] In the above embodiment, when the electronic atomizing device is inhaled, the airflow direction is: air inlet 241 → atomizing chamber 5 → connecting hole 1412 → insertion hole 1411 → air guide 15 → first docking hole 1321 on top cover 132 → suction channel 1331.

[0085] Please refer to Figure 3 and Figure 4 In some embodiments, the opening through which the air inlet 241 communicates with the atomizing tank 2211 is located on the side wall of the atomizing tank 2211, which can prevent the aerosol generating base liquid from flowing into the air inlet 241, thereby preventing leakage of the aerosol generating base liquid.

[0086] Please refer to Figure 3 In some embodiments, the opening connecting the air inlet 241 and the atomizing groove 2211 is located downstream of the atomizing component 3, so that the airflow flowing from the air guide column 24 into the atomizing chamber 5 can be blown from the side of the atomizing component 3 to the center of the atomizing component 3, so as to blow the aerosol generating base liquid to the center of the atomizing component 3, thereby preventing the aerosol generating base liquid from flowing into the air inlet 241 and thus preventing the aerosol generating base liquid from leaking.

[0087] Please refer to Figure 5 In some embodiments, the second chamber 2 further includes a wiring post 25 that penetrates the substrate 221 and the second seal 23. The wiring post 25 has a wiring hole 251 for accommodating the wires of the atomizing assembly 3 and the heating assembly 4.

[0088] In the above embodiments, the wires of the atomizing component 3 and the heating component 4 are housed in the wiring hole 251 to prevent the wires of the atomizing component 3 and the heating component 4 from contacting the aerosol generating base liquid, thereby avoiding short circuits and preventing the wires of the atomizing component 3 and the heating component 4 from being corroded by the aerosol generating base liquid.

[0089] Please refer to Figure 4 In some embodiments, the base plate 221, the first side wall 222, the second side wall 223, the plug post 2213, the oil guide post 2215, the air guide post 24 and the wiring post 25 in the second compartment 2 are integrally formed.
