Description

Technical Field

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

[0002] An electronic atomizing device is a device that heats an aerosol matrix through an atomizing unit, causing the heated aerosol matrix to be atomized into an aerosol for the user to inhale.

[0003] In existing electronic atomizing devices, the heating element is typically electrically connected to the control circuit board via pins, which are then fixed to the inner wall of the atomizing tube by a mounting bracket. During use, electronic atomizing devices release significant heat and high-temperature aerosol. Some of this heat is transferred to the mounting bracket, and the aerosol also adheres to it. With prolonged use, the plastic mounting bracket ages due to the high temperatures and the aerosol matrix, primarily composed of propylene glycol (PG), glycerin (VG), nicotine, and flavorings, leading to the release of harmful substances and impacting user health. Therefore, the existing mounting bracket requires improvement. Utility Model Content

Detailed Implementation

[0047] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0049] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0050] Please seeFigures 1-3 As shown, this application provides an atomizing core 1, which includes an atomizing tube 11, a heating element 12, and a mounting base 13. The atomizing tube 11 has an air inlet end 111, through which external airflow enters and mixes with the generated aerosol. The heating element 12 includes an electrically connected heating element 121 and a lead 122. The heating element 121 is disposed within the atomizing tube 11 and is used to heat the aerosol matrix when energized, causing the heated aerosol matrix to atomize and generate aerosol. The lead 122 extends from the air inlet end 111 into the atomizing tube 11. The heating element 121 is electrically connected to the power module 20 and the control module, so that the power module 20 can supply power to the heating element 121, and the control module can control the heating element 121 to heat up or stop heating; the fixing base 13 is at least partially disposed inside the atomizing tube 11, and is used to limit the pin 122 so that the pins 122 do not come into contact with each other and cause a short circuit, and to prevent the heating element 121 from becoming loose due to the pins 122 not being limited.

[0051] Furthermore, the fixing base 13 is made of porous ceramic material, which gives it good chemical and thermal stability, thus providing resistance to acid and alkali corrosion and high temperature. This allows the fixing base 13 to stably limit and fix the pin 122 without releasing harmful substances due to aerosol adhesion or high temperature. In addition, the fixing base 13 made of porous ceramic material can also increase the aerosol adsorption area by utilizing the large surface area of ​​porous ceramic due to its high porosity, reducing the risk of aerosol spreading away from the nozzle 3 towards the battery rod, thereby reducing the impact on the control module and power module 20. It also effectively locks in the condensate formed after the aerosol cools down, further reducing the risk of condensate flowing into the control module and power module 20.

[0052] Further, please refer to Figures 2-3 As shown, the fixing base 13 extends along the axial direction of the atomizing tube 11 and forms at least two grooves 131, with the opening of each groove 131 facing the inner wall of the atomizing tube 11; the heating element 12 includes at least two pins 122, with each pin 122 passing through one of the grooves 131.

[0053] By setting the groove 131 so that its opening faces the inner wall of the atomizing tube 11, the fixing seat 13 can easily cooperate with the atomizing tube 11 to limit and fix the pin 122, reducing the difficulty of assembly.

[0054] Furthermore, the opening of the groove 131 gradually increases along the radial direction of the fixing seat 13, so that the opening of the groove 131 gradually increases, thereby facilitating the placement of the pins 122 in one of the grooves 131 respectively.

[0055] In one embodiment, the number of grooves 131 is the same as the number of pins 122, so that each groove 131 is respectively provided with one pin 122, thereby making the periphery of the fixing seat 13 and the inner wall of the corresponding atomizing tube 11 fit tightly, thereby preventing the condensate attached to the inner wall of the atomizing tube 11 between the heating element 121 and the fixing seat 13 from flowing out of the atomizing tube 11 through the grooves 131 and causing condensate leakage.

[0056] In another embodiment, the number of grooves 131 is greater than the number of pins 122, so that the pins 122 can be arbitrarily inserted into a groove 131, thereby reducing the accuracy requirements for the fit between the grooves 131 and the pins 122 when assembling the mounting base 13, and effectively improving the installation efficiency.

[0057] Further, please refer to Figure 3 As shown, the mounting base 13 includes a first section 132 and a second section 133. The first section 132 is close to the air inlet end 111, and the second section 133 is close to the heating element 121. The outer diameter of the first section 132 is larger than the outer diameter of the second section 133, and the first section 132 is at least partially press-fitted into the atomizing tube 11. The outer diameter of the second section 133 is smaller than the inner diameter of the atomizing tube 11, so that the second section 133 does not contact the inner wall of the atomizing tube 11, thereby forming a liquid collection groove 14 together with the outer wall of the second section 133 and the inner wall of the atomizing tube 11 on the periphery.

[0058] By setting the liquid collection tank 14, the condensate attached to the inner wall of the atomizing tube 11 between the heating element 121 and the second section 133 can be effectively collected and temporarily stored, reducing the risk of condensate leakage, so that the condensate can be gradually absorbed and locked by the holes of the fixing seat 13.

[0059] Furthermore, the groove 131 extends at least through the first section 132 along the axial direction of the atomizing tube 11, so that the pin 122 passes through the liquid collection tank 14 and the groove 131 respectively and extends out of the atomizing tube 11. This allows the condensate flowing down along the pin 122 to smoothly enter the liquid collection tank 14 under the guidance of the pin 122, thereby reducing the risk of leakage of this part of the condensate.

[0060] Furthermore, the number of grooves 131 is the same as the number of pins 122; each pin 122 includes a wire 123 and an insulating layer 124, and the insulating layer 124 of each pin 122 is sealed and filled between the groove 131 corresponding to the second segment 133 and the inner wall of the atomizing tube 11, thereby sealing the groove 131 by the pin 122, which can effectively prevent the condensate in the collection tank 14 from leaking from the groove 131.

[0061] Furthermore, in one embodiment, the fixing base 13 extends along the axial direction of the atomizing tube 11 and forms at least two limiting holes; the heating element 121 includes at least two pins 122, each pin 122 passing through one of the limiting holes. By providing the limiting holes, the pins 122 can be directly inserted into one of the limiting holes, thereby limiting the position of the pins 122.

[0062] Further, please refer to Figures 1-2 As shown, the inner wall of the atomizing tube 11 has a liquid passage hole 112, which is used to allow the aerosol matrix to enter the atomizing tube 11; the atomizing core 1 also includes a liquid guiding component 15, which is disposed inside the atomizing tube 11 and covers the liquid passage hole 112, and the aerosol matrix entering the atomizing tube 11 will enter the liquid guiding component 15; the heating element 121 is disposed on the inner wall of the liquid guiding component 15 and is used to heat the aerosol matrix absorbed by the liquid guiding component 15, so that the heated aerosol matrix is ​​atomized to generate aerosol and diffuse into the atomizing tube 11.

[0063] The liquid guiding component 15 is made of porous ceramic material or cotton material, so that the liquid guiding component 15 has the ability to lock in the aerosol matrix, thereby effectively preventing the aerosol matrix from leaking after passing through the liquid passage 112.

[0064] On the other hand, please see Figures 4-5 and combined Figures 1-3 As shown, this application also provides an atomizer 10, which includes the atomizing core 1 described in any of the above claims. Therefore, the atomizer 10 has all the aforementioned beneficial effects, which will not be repeated here.

[0065] Further, please refer to Figure 5 and Figure 7As shown, the atomizer 10 also includes a housing 2 and a mouthpiece 3. The housing 2 is configured to form a first receiving space 21. The atomizing core 1 is disposed in the first receiving space 21, and a liquid storage chamber 4 is formed between the outer wall of the atomizing tube 11 and the first receiving space 21. The liquid storage chamber 4 is used to contain the aerosol matrix, and the liquid passage 112 is connected to the liquid storage chamber 4. The atomizing tube 11 also has an air outlet 113. The air inlet 111 and the air outlet 113 are the two opposite ends of the atomizing tube 11. The mouthpiece 3 is disposed on the housing 2 and is connected to the air outlet 113. When in use, the aerosol diffused into the atomizing tube 11 will pass through the air outlet 113 and the mouthpiece 3 and leave the atomizer 10 along with the user's inhalation.

[0066] Further, please refer to Figure 5 As shown, the housing 2 includes an outer shell 22, an inner shell 23, a first sealing seat 24, and a second sealing seat 25. The inner shell 23, the first sealing seat 24, and the second sealing seat 25 are respectively disposed inside the outer shell 22, and the length of the inner shell 23 along the axial direction of the atomizing tube 11 is less than the length of the outer shell 22.

[0067] The first sealing seat 24 and the second sealing seat 25 are respectively sealed to the opposite ends of the inner shell 23, so that the inner shell 23 and the first sealing seat 24 and the second sealing seat 25 define the first receiving space 21, and the first sealing seat 24 is close to the air outlet 113, and the second sealing seat 25 is close to the air inlet 111.

[0068] The nozzle 3 is sealed and inserted into the outer shell 22 via the first sealing seat 24, and connects the air outlet 113 to the outside. The atomizing tube 11 is sealed and inserted into the second sealing seat 25 near the outer wall of the air inlet 111, and the atomizing tube 11 is sealed and inserted into the first sealing seat 24 near the outer wall of the air outlet 113. Thus, the liquid storage chamber 4 is defined between the first sealing seat 24, the second sealing seat 25, the inner wall of the inner shell 23, and the outer wall of the atomizing tube 11.

[0069] Furthermore, the first sealing seat 24 includes a first ring portion 241, a second ring portion 242, and a third ring portion 243 connected sequentially along the axial direction of the atomizing tube 11. The diameter of the second ring portion 242 is larger than the diameter of the first ring portion 241. The first ring portion 241 is sealed and inserted into the mouthpiece 3. The second ring portion 242 is sealed and abutted between the mouthpiece 3 and the inner shell 23. The third ring portion 243 is sealed and inserted between the inner shell 23 and the inner wall of the atomizing tube 11 near the air outlet 113.

[0070] The second sealing seat 25 includes a fourth ring portion 251 and a fifth ring portion 252. The diameter of the fourth ring portion 251 is smaller than the diameter of the fifth ring portion 252. The fourth ring portion 251 is sealed and inserted between the inner shell 23 and the inner wall of the atomizing tube 11 near the air inlet end 111. The fifth ring portion 252 is sealed and abuts against the end of the inner tube away from the mouthpiece 3.

[0071] Furthermore, the atomizer 10 also includes a liquid storage cotton 5, which is disposed in the liquid storage chamber 4 and is used to lock the aerosol matrix in the liquid storage chamber 4, thereby reducing the hydraulic pressure at the liquid passage hole 112 and preventing the aerosol matrix in the liquid storage chamber 4 from leaking from the liquid passage hole 112.

[0072] Furthermore, the first sealing seat 24 near the end of the nozzle 3 is configured with an installation groove 244 and a first installation hole 245. The installation groove 244 connects the nozzle 3 and the first installation hole 245. The atomizing tube 11 near the outer wall of the outlet end 113 is sealed and inserted into the first installation hole 245, so that the part of the atomizing tube 11 near the outlet end 113 is sealed and separated from the liquid storage tank 4 through the first installation hole 245.

[0073] Furthermore, the atomizer 10 also includes a first liquid suction member 6, which is disposed in the mounting groove 244 and has a first through hole 61. The first through hole 61 connects the nozzle 3 and the first mounting hole 245. By setting the first liquid suction member 6, the condensate remaining on the inner wall of the nozzle 3 can be effectively adsorbed, thus preventing the condensate from flowing back and leaking.

[0074] On the other hand, please refer to Figures 6-8 and combined Figures 1-5 As shown, this application also provides an electronic atomizing device 100, which includes the atomizer 10 described in any of the above claims. Therefore, the electronic atomizing device 100 possesses all the aforementioned beneficial effects, which will not be repeated here.

[0075] Furthermore, the housing 2 also includes a base 26, which is disposed on the outer shell 22 and forms a second receiving space 27 between the base 26, the second sealing seat 25, and the outer shell 22. The second receiving space 27 is separated from the first receiving space 21 by the second sealing seat 25.

[0076] The electronic atomizing device 100 also includes a power module 20 and a control module. The power module 20 and the control module are respectively disposed in the second receiving space 27, and the control module is electrically connected to the power module 20 and the pin 122 respectively. The first receiving space 21 and the second receiving space 27 are respectively formed by the outer shell 22 in cooperation with the first sealing seat 24, the inner shell 23, the second sealing seat 25 and the base 26, which are arranged along the axial direction of the atomizing tube 11. This makes the electronic atomizing device 100 as a whole slender, thereby effectively increasing the heat dissipation area of ​​the second receiving space 27, and thus allowing the heat generated by the power module 20 and the control module to be dissipated more efficiently during operation.

[0077] Further, please refer to Figure 5 As shown, the second sealing seat 25 is configured to form a second mounting hole 253. The outer wall of the atomizing tube 11 near the air inlet 111 is sealed and inserted into the second mounting hole 253, so that the portion of the atomizing tube 11 near the air inlet 111 is sealed and separated from the liquid storage tank 4 through the second mounting hole 253. The second mounting hole 253 connects the atomizing tube 11 and the second receiving space 27. Therefore, the external airflow will flow sequentially through the second receiving space 27, the second mounting hole 253, the atomizing tube 11, the first mounting hole 245, the first through hole 61 and the mouthpiece 3 before leaving the electronic atomizing device 100.

[0078] Further, please refer to Figure 8 As shown, the electronic atomizing device 100 further includes a second liquid-absorbing element 30, which is disposed between the second sealing seat 25 and the power module 20, and located directly below the second mounting hole 253 in the direction from the air outlet 113 to the air inlet 111. By providing the second liquid-absorbing element 30, even if condensate flows through the second mounting hole 253 into the second receiving space 27, it can be absorbed and locked by the second liquid-absorbing element 30, thereby preventing the condensate from corroding the power module 20 and the control module, causing corrosion and damage to the power module 20 and the control module. In addition, it can also effectively prevent condensate passing through the second mounting hole 253 from leaking from the base 26.

[0079] Further, please refer to Figure 5As shown, the second sealing seat 25 has a plurality of protrusions 254 formed at one end near the second liquid suction member 30. The plurality of protrusions 254 are spaced apart so that there is a gap between adjacent protrusions 254 that connects to the second receiving space 27, so that the airflow in the second receiving space 27 can pass smoothly through the gap and enter the atomizing tube 11 from the second mounting hole 253.

[0080] Further, please refer to Figures 7-8 As shown, the electronic atomizing device 100 also includes an airflow sensor 40, which is electrically connected to the control module. The airflow sensor 40 is used to detect whether there is airflow and send a feedback signal to the control module when airflow is detected, so that the control module controls the heating element 12 to heat up according to the feedback signal.

[0081] The base 26 has a first air inlet 261, a second air inlet 262, and a third mounting hole 263. The airflow sensor 40 is located in the third mounting hole 263. The first air inlet 261 connects the third mounting hole 263 to the outside, so that external airflow passes through the first air inlet 261 into the second air inlet 262. When the airflow sensor 40 passes through the second air inlet 262, it triggers the airflow sensor 40 to send the feedback signal to the control module. The second air inlet 262 connects the second receiving space 27 to the outside, and is used to allow external airflow to enter the electronic atomizing device 100.

[0082] By using the first air inlet 261 and the second air inlet 262, the external airflow enters the electronic atomizing device 100 through the first air inlet 261 and the second air inlet 262 and then flows sequentially over the surfaces of the power module 20 and the control module located in the second receiving space 27, thereby achieving heat dissipation for the control module and the power module 20. Conversely, the heat from the power module 20 and the control module is used to preheat the airflow, preventing the aerosol from easily cooling down and forming condensate due to the low-temperature airflow.

[0083] Furthermore, the third mounting hole 263 is located directly below the power module 20, and a third liquid-absorbing member 50 is provided between the power module 20 and the third mounting hole 263. The third liquid-absorbing member 50 is attached to the end of the power module 20 away from the second sealing seat 25 and is partially located above the third mounting hole 263. By providing the third liquid-absorbing member 50 and placing the third mounting hole 263 directly below the power module 20, the airflow sensor 40 can be effectively protected, preventing liquid entering the second space from corroding the airflow sensor and causing it to self-start or even be damaged.

[0084] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0085] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0086] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
