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 transforms a liquid aerosol generating matrix into an aerosol through atomization or other means. When a 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 liquid reservoir and an atomizing coil. The liquid reservoir is fitted around the atomizing coil to provide the aerosol generating matrix, allowing the atomizing coil to heat the matrix and generate an aerosol.

[0003] In related technologies, the liquid storage component is directly housed in the liquid storage chamber, so that the liquid storage component is always immersed in the aerosol generating matrix in the liquid storage chamber. When the liquid storage rate of the liquid storage component reaches 100%, the aerosol generating matrix is ​​easily squeezed out of the liquid storage component and flows into the atomizing air channel, which makes the aerosol generating matrix easy to leak through the atomizing air channel, resulting in a high risk of liquid leakage in the electronic atomizing device. Utility Model Content

[0004] The purpose of this application is to provide an electronic atomizing device that addresses the technical problem of high leakage risk in electronic atomizing devices.

[0005] To achieve the above objectives, the technical solution adopted in this application embodiment is: an electronic atomizing device, including a housing assembly and an atomizing assembly.

[0006] The housing assembly has a liquid storage chamber for storing a liquid aerosol generating matrix. The atomizing assembly is disposed within the housing assembly and has an atomizing chamber, an atomizing air passage penetrating the atomizing chamber, and a liquid passage communicating with the atomizing chamber. The atomizing air passage communicates with the liquid passage through the atomizing chamber, and the liquid storage chamber communicates with the liquid passage. The aerosol generating matrix located in the liquid storage chamber can generate surface tension at the liquid passage. The atomizing assembly includes a liquid storage element and an atomizing core. Both the atomizing core and the liquid storage element are housed in the atomizing chamber. The atomizing core is used to heat the aerosol generating matrix provided by the liquid storage element to generate aerosol within the atomizing air passage.

[0007] The beneficial effects of the electronic atomizing device provided in this application are as follows: the surface tension of the aerosol generating matrix at the liquid passage can prevent the aerosol generating matrix from flowing into the atomizing chamber. Since the atomizing air passage is connected to the liquid passage through the atomizing chamber, a suction force will be formed on the side of the liquid passage near the atomizing chamber when the user inhales. When the suction force is greater than the surface tension of the aerosol generating matrix at the liquid passage, the aerosol generating matrix flows into the atomizing chamber through the liquid passage, thus achieving oil supply during inhalation. This can prevent the liquid storage component in the atomizing chamber from always being immersed in the aerosol generating matrix, reduce the risk of the aerosol generating matrix in the liquid storage component being squeezed out and flowing into the atomizing air passage, and thus reduce the risk of leakage of the electronic atomizing device.

[0008] In some embodiments, the atomizing component further includes a buffer chamber connected to the liquid passage, and the buffer chamber is connected to the liquid storage chamber, wherein the volume of the liquid storage chamber is greater than the volume of the buffer chamber.

The main body is a cavity structure with openings at both ends, namely a first opening and a second opening. The partition is located inside the main body and extends from the end face around the first opening to the second opening. The partition encloses an installation space communicating with the first opening. The third seal covers the second opening. The third seal, the main body, and the partition enclose the liquid storage chamber. The atomizing assembly is disposed within the installation space.

[0012] In some embodiments, the partition is provided with a mounting hole, and the atomizing component has a plug-in portion that is plugged into the mounting hole.

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] In this specification, references to "one embodiment," "some embodiments," or simply "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0032] An electronic atomizing device is a product that transforms a liquid aerosol generating matrix into an aerosol through atomization or other means. When a 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 liquid reservoir and an atomizing coil. The liquid reservoir is fitted around the atomizing coil to provide the aerosol generating matrix, allowing the atomizing coil to heat the matrix and generate an aerosol.

[0033] In related technologies, the liquid storage component is directly housed in the liquid storage chamber, so that the liquid storage component is always immersed in the aerosol generating matrix in the liquid storage chamber. When the liquid storage rate of the liquid storage component reaches 100%, the aerosol generating matrix is ​​easily squeezed out of the liquid storage component and flows into the atomizing air channel, which makes the aerosol generating matrix easy to leak through the atomizing air channel, resulting in a high risk of liquid leakage in the electronic atomizing device.

[0034] In view of the above problems, this application provides an electronic atomizing device to solve the technical problem of high leakage risk in electronic atomizing devices.

[0035] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0036] Please refer to Figure 1 This application provides an electronic atomizing device, including a housing assembly 1 and an atomizing assembly 2.

[0037] The housing assembly 1 has a liquid storage chamber 11 for storing liquid aerosol generating matrix; the atomizing assembly 2 is disposed inside the housing assembly 1, and the atomizing assembly 2 has an atomizing chamber 21, an atomizing air passage 22 penetrating the atomizing chamber 21, and a liquid passage 271 communicating with the atomizing chamber 21. The atomizing air passage 22 communicates with the liquid passage 271 through the atomizing chamber 21, and the liquid storage chamber 11 communicates with the liquid passage 271. The aerosol generating matrix located in the liquid storage chamber 11 can form a liquid surface tension at the liquid passage 271; the atomizing assembly 2 includes a liquid storage element 23 and an atomizing core 24. Both the atomizing core 24 and the liquid storage element 23 are housed in the atomizing chamber 21. The atomizing core 24 is used to heat the aerosol generating matrix provided by the liquid storage element 23 to generate aerosol in the atomizing air passage 22.

[0038] In the electronic atomizing device provided in this application, the surface tension of the aerosol generating matrix at the liquid passage 271 can prevent the aerosol generating matrix from flowing into the atomizing chamber 21. Since the atomizing air passage 22 is connected to the liquid passage 271 through the atomizing chamber 21, a suction force will be formed on the side of the liquid passage 271 near the atomizing chamber 21 when the user inhales. When the suction force is greater than the surface tension of the aerosol generating matrix at the liquid passage 271, the aerosol generating matrix flows into the atomizing chamber 21 through the liquid passage 271, thus achieving liquid supply during inhalation. This can prevent the liquid storage component 23 in the atomizing chamber 21 from always being immersed in the aerosol generating matrix, reduce the risk of the aerosol generating matrix in the liquid storage component 23 being squeezed out and flowing into the atomizing air passage 22, and thus reduce the risk of leakage of the electronic atomizing device.

[0039] It should be noted that surface tension is the tension acting along any boundary line on the surface of a liquid due to the uneven molecular attraction of the liquid surface layer. In the embodiments of this application, when the liquid aerosol generating matrix covers the liquid passage 271, a surface tension F will be generated at the liquid passage 271. 张 .

[0040] It should be noted that liquids exert pressure on the container walls or object surfaces due to their own gravity. In this embodiment, the liquid aerosol generating matrix has a pressure F at the liquid passage 271. 液 And F 液 Direction and F 张 The directions are opposite.

[0041] When the electronic atomizer is not being used, F 液 =F 张 The liquid aerosol generation matrix will not actively flow into the atomization chamber 21 through the liquid hole 271.

[0042] When the electronic atomizing device is drawn in, the airflow inside the atomizing chamber 21 flows out of the electronic atomizing device, causing the pressure inside the atomizing chamber 21 to decrease. This creates a force F pointing towards the atomizing chamber 21 at the liquid passage 271.吸 And F is required 吸 +F 液 >F 张 Only then can the liquid aerosol generation matrix overcome the surface tension F at the liquid passage 271. 张 Flow into atomization chamber 21.

[0043] The equilibrium equation obtained from the capillary rise method for measuring liquid surface tension is: γ*2πrcosθ=ρghπr*r, then γ=ρghr / (2cosθ), where γ is the surface tension, r is the radius of the capillary (r corresponds to the radius of the liquid passage 271 in this embodiment), h is the height of the liquid level rise in the capillary (h corresponds to the height or depth of the liquid aerosol generation matrix in the liquid passage 271 in this embodiment), ρ is the density of the measured liquid (ρ corresponds to the density of the liquid aerosol generation matrix in this embodiment), g is the local gravitational acceleration, and θ is the contact angle between the liquid and the tube wall (θ corresponds to the contact angle between the liquid aerosol generation matrix and the wall of the liquid passage 271 in this embodiment).

[0044] The above analysis shows that the radius of the liquid passage 271 affects F. 液 =F 张 The key to balance is the radius of the liquid passage 271, which is crucial to the fuel supply efficiency of the electronic atomizing device.

[0045] It should be noted that the F produced during inhalation by the electronic atomizing device can be used as a reference. 吸 (This can be measured experimentally) and the pressure F generated by the liquid aerosol generating matrix on the side of the liquid passage 271 away from the atomizing chamber 21. 液 (F 液 The density of the liquid aerosol generating matrix and the height of the liquid aerosol generating matrix located on the side of the liquid passage 271 away from the atomizing chamber 21 are determined. These two quantities can be determined after the liquid aerosol generating matrix is ​​injected into the electronic atomizing device, i.e., F. 液 (A definite quantity) is derived from F 吸 +F 液 =F 张 The state changes to F 吸 +F 液 >F 张 F in state 张 The value can be used to calculate the radius of the liquid passage 271.

[0046] Please refer to Figure 1 and Figure 2 In some embodiments, the atomizing component 2 also has a buffer chamber 25 connected to the liquid passage 271, and the buffer chamber 25 is connected to the liquid storage chamber 11, the volume of the liquid storage chamber 11 being greater than the volume of the buffer chamber 25.

[0047] It should be noted that after the aerosol generating matrix in the buffer chamber 25 submerges the liquid passage 271, the buffer chamber 25 and the liquid storage chamber 11 will form a closed space. Therefore, in the equilibrium state (F... 储液仓 =F 缓冲仓 Under these conditions, the liquid level in buffer tank 25 and the liquid level in storage tank 11 will remain unchanged, where F 储液仓 F is the sum of the pressure F1 generated at the connection between the buffer chamber 25 and the storage chamber 11 by the aerosol generation matrix in the storage chamber 11, and the gas pressure F2 inside the storage chamber 11. 缓冲仓 F2 is the sum of the pressure F3 generated by the aerosol generating matrix at the connection between the buffer chamber 25 and the storage chamber 11, and the air pressure F4 within the buffer chamber 25. Since the air pressure in a closed space is closely related to its volume (i.e., the smaller the volume, the higher the air pressure), the above embodiment limits the volume of the storage chamber 11 to be greater than the volume of the buffer chamber 25, ensuring that F2 is less than F4 in an equilibrium state, thus resulting in F3 being less than F1. Both F1 and F3 are related to the height of the aerosol generating matrix; if F3 is less than F1, it indicates that the height of the aerosol generating matrix within the buffer chamber 25 is less than the height of the aerosol generating matrix within the storage chamber 11.

[0048] Therefore, in the above embodiments, by setting a buffer chamber 25 and having a volume of liquid storage chamber 11 greater than that of the buffer chamber 25, the height of the aerosol generating matrix on the side of the liquid passage 271 away from the atomizing chamber 21 can be reduced, thereby reducing the pressure of the aerosol generating matrix on the side of the liquid passage 271 away from the atomizing chamber 21 on the liquid passage 271.

[0049] Please refer to Figure 2 In some embodiments, the atomizing assembly 2 further includes a cup 26, a partition plate 27, a first seal 28, and a second seal 29; the first seal 28 and the second seal 29 are respectively disposed at both ends of the cup 26, the first seal 28 is provided with an air outlet 281, the second seal 29 is provided with an air inlet 291, the atomizing core 24 is connected to the second seal 29, and the air inlet 291, the air outlet 281, and the atomizing core 24 form an atomizing air passage 22; the partition plate 27 is located between the atomizing core 24 and the cup 26, and the atomizing chamber 21 is formed between the partition plate 27 and the atomizing core 24, the buffer chamber 25 is formed between the partition plate 27 and the cup 26, and the liquid passage 271 is opened on the partition plate 27.

[0050] The above settings make the structure of each component of the atomizing component 2 relatively simple and the cost low, and also make it easy to disassemble and assemble the atomizing component 2.

[0051] Please refer to Figure 4In some embodiments, the partition plate 27 is flat, and there are two partition plates 27. Each partition plate 27 has a liquid passage hole 271. The two partition plates 27 are spaced apart, forming an atomizing chamber 21 between the two partition plates 27. A buffer chamber 25 is formed between the partition plate 27 and the cup 26. There are two buffer chambers 25, which are located on opposite sides of the atomizing chamber 21. This allows the aerosol generating matrix to enter the atomizing chamber 21 from opposite sides of the liquid storage component 23. This allows the liquid storage component 23 to contact and adsorb the aerosol generating matrix flowing into the atomizing chamber 21 through the liquid passage hole 271 more evenly.

[0052] In other embodiments, the partition plate 27 is cylindrical in shape, and the partition plate 27 surrounds the atomizing chamber 21. The partition plate 27 and the cup 26 are spaced apart to form a buffer chamber 25 surrounding the atomizing chamber 21 between the partition plate 27 and the cup 26. The partition plate 27 is provided with a plurality of liquid passage holes 271, which are evenly arranged along the circumference of the partition plate 27. This allows the liquid storage component 23 to contact and adsorb the aerosol generation matrix that flows into the atomizing chamber 21 through the liquid passage holes 271 in a more uniform manner.

[0053] Please refer to Figure 2 and Figure 3 In some embodiments, the first sealing member 28 is provided with an air guide portion 282, and an air outlet 281 passes through the air guide portion 282. The liquid storage member 23 is provided with a through hole 231, and the air guide portion 282 passes through the through hole 231. The liquid storage member 23 and the first sealing member 28 are spaced apart. The atomizing core 24 is housed in the through hole 231, and the atomizing core 24 and the air guide portion 282 are spaced apart. Both the atomizing core 24 and the air guide portion 282 are clearance-fitted with the through hole 231.

[0054] In the above embodiment, since both the atomizing core 24 and the air guide 282 are clearance-fitted with the through hole 231, and the liquid storage component 23 and the first sealing component 28 are spaced apart, the gap between the atomizing core 24 and the through hole 231 and the gap between the liquid storage component 23 and the first sealing component 28 can be interconnected (as part of the atomizing chamber 21). Furthermore, since the atomizing core 24 and the air guide 282 are spaced apart, the atomizing core 24 can connect with the gap between the atomizing core 24 and the through hole 231, thereby allowing the atomizing core 24 to communicate with the atomizing chamber 21. Since the atomizing core 24 is part of the atomizing air passage 22, the above arrangement allows the atomizing air passage 22 to communicate with the atomizing chamber 21. When inhaling the electronic atomizing device, the airflow passes through the atomizing air passage 22 and causes the gas in the atomizing chamber 21 to flow along... Figure 2 The flow path shown by the dashed line reduces the air pressure inside the atomizing chamber 21, thereby generating a force F pointing towards the atomizing chamber 21 at the liquid passage 271. 吸 And make F 吸 +F 液 >F张 This allows the liquid aerosol generation matrix to overcome the surface tension F at the liquid passage 271. 张 It flows into the atomizing chamber 21 to supply liquid during suction.

[0055] It should be noted that when the liquid storage component 23 is spaced apart from the inner wall of the atomizing chamber 21, the liquid storage component 23 is prone to shaking within the atomizing chamber 21. This is not conducive to the uniform adsorption of the aerosol generation matrix by the liquid storage component 23, nor is it conducive to the supply of the aerosol generation matrix from the liquid storage component 23 to the atomizing core 24. Furthermore, when shaking, the liquid storage component 23 is prone to colliding with the atomizing core 24, causing the aerosol generation matrix within the liquid storage component 23 to be squeezed out and flow into the atomizing air passage 22, resulting in leakage. To prevent the liquid storage component 23 from shaking, in this embodiment, both the partition plate 27 and the cup 26 are in contact with the outer wall of the liquid storage component 23 to limit the position of the liquid storage component 23.

[0056] Please refer to Figure 3 In some embodiments, the liquid storage component 23 is provided with an air guide groove 232, which extends through the liquid storage component 23 in the extension direction of the atomizing air channel 22, and the air guide groove 232 is connected to the liquid passage hole 271.

[0057] With the above arrangement, the two ends of the air guide groove 232 are respectively connected to the liquid hole 271 and the gap between the liquid storage component 23 and the first sealing component 28. Therefore, when the partition plate 27 and the cup 26 are in contact with the outer wall of the liquid storage component 23, the gas in the atomizing chamber 21 can flow along the air guide groove 232 (which is... Figure 2 (Part of the flow path shown by the dashed line) flows, thereby reducing the air pressure inside the atomizing chamber 21, and thus forming a force F pointing towards the atomizing chamber 21 at the liquid passage 271. 吸 And make F 吸 +F 液 >F 张 This allows the liquid aerosol generation matrix to overcome the surface tension F at the liquid passage 271. 张 It flows into the atomizing chamber 21 to supply liquid during suction.

[0058] Please refer to Figure 3 In some embodiments, the atomizing core 24 includes a fixed cylinder 241, a liquid guiding component 242, a heating mesh 243, and a fixing base 244. The fixing base 244 is connected to the second sealing component 29, the heating mesh 243 surrounds the inner wall of the fixed cylinder 241, and the liquid guiding component 242 is disposed between the inner wall of the fixed cylinder 241 and the heating mesh 243. The fixed cylinder 241 is provided with a liquid inlet hole 2411, and the liquid guiding component 242 contacts the aerosol generation matrix in the liquid storage component 23 through the liquid inlet hole 2411.

[0059] In the above embodiment, the liquid guide 242 contacts the aerosol generating matrix in the liquid storage 23 through the liquid inlet 2411, and the heating mesh 243 contacts the aerosol generating matrix through the liquid guide 242. This not only controls the supply rate of the aerosol generating matrix, but also controls the contact area between the heating mesh 243 and the aerosol generating matrix. This ensures that when the contact area of ​​the aerosol generating matrix in the liquid storage 23 decreases, the entire area of ​​the heating mesh 243 can still contact the aerosol generating matrix through the liquid guide 242, thus preventing some of the heating mesh 243 from dry burning due to lack of contact with the aerosol generating matrix.

[0060] Please refer to Figure 6 In some embodiments, the housing assembly 1 includes a housing 12 and a third seal 13. The housing 12 includes a main body 121 and a partition 122. The main body 121 is a cavity structure with openings at both ends. The two openings are a first opening 1211 and a second opening 1212, respectively. The partition 122 is located inside the main body 121 and extends from the end face around the first opening 1211 to the second opening 1212. The partition 122 encloses and forms an installation space 1221 that communicates with the first opening 1211. The third seal 13 covers the second opening 1212. The third seal 13, the main body 121, and the partition 122 enclose and form a liquid storage chamber 11. The atomizing assembly 2 is disposed in the installation space 1221.

[0061] The above configuration makes the structure of each component of the housing assembly 1 relatively simple and the cost low, and facilitates the assembly and disassembly of the housing assembly 1 and the atomizing assembly 2.

[0062] Please refer to Figure 1 , Figure 5 and Figure 6 In some embodiments, the partition 122 is provided with a mounting hole 1222, and the atomizing component 2 has a plug-in portion 261, which is plugged into the mounting hole 1222.

[0063] With the above configuration, the atomizing component 2 and the housing component 1 are connected to each other by a plug-in method, which simplifies the connection structure between the housing component 1 and the atomizing component 2, and facilitates the disassembly and assembly of the housing component 1 and the atomizing component 2.

[0064] Please refer to Figure 1 , Figure 5 and Figure 6 In some embodiments, the third seal 13 is provided with a connecting groove 131, the opening of the connecting groove 131 faces the liquid storage tank 11 and the opening of the connecting groove 131 faces the mounting hole 1222, the plug-in part 261 is provided with a connecting hole 262, and the connecting groove 131 and the buffer tank 25 are both connected to the connecting hole 262.

[0065] The above configuration allows the liquid storage tank 11, the connecting groove 131, the connecting hole 262, and the buffer tank 25 to be connected in sequence.

[0066] Please refer to Figure 5 and Figure 6 The atomizing component 2 also includes a fifth seal 210, which is sleeved on the periphery of the insertion part 261.

[0067] With the above configuration, when the insertion part 261 is inserted into the mounting hole 1222 on the partition part 122, the fifth sealing member 210 can abut against the inner wall surface of the mounting hole 1222 to seal the gap between the insertion part 261 and the mounting hole 1222 and prevent leakage.

[0068] Please refer to Figure 6 and Figure 7 In some embodiments, the housing assembly 1 further includes a fourth seal 14, which is disposed on the side of the third seal 13 away from the liquid storage chamber 11. The third seal 13 and the fourth seal 14 surround to form a liquid collection chamber 15, which is used to contain the aerosol generation matrix flowing out through the atomizing air passage 22.

[0069] With the above configuration, the liquid collection chamber 15 is used to contain the aerosol generation matrix flowing out through the atomizing air passage 22, which can prevent the aerosol generation matrix from flowing out of the housing assembly 1, so as to avoid the aerosol generation matrix flowing out of the electronic atomizing device and thus not adversely affecting the user experience of the electronic atomizing device.

[0070] Please refer to Figure 6 and Figure 7 In some embodiments, the housing assembly 1 further includes a liquid suction member 16, which is housed in a liquid collection chamber 15.

[0071] With the above configuration, the liquid suction component 16 can adsorb the aerosol generation matrix in the liquid collection chamber 15 to prevent the aerosol generation matrix from flowing.
