Description

Technical Field

[0001] This application belongs to the technical field of electronic atomization, and more specifically, relates to an atomization core and an electronic atomization device. Background Art

[0002] The atomization core is the core component of an electronic atomization device, which is used to heat and atomize an aerosol-forming matrix when powered on to form an aerosol for users to consume. Among them, the aerosol-forming matrix can be e-liquid, health care drugs, therapeutic drugs, etc. For example, when the aerosol-forming matrix is e-liquid, the electronic atomization device can also be called an e-cigarette. The lithium battery in the e-cigarette drives and heats different resistance heating elements in the atomization core to output heat with different powers, so as to heat and atomize the e-liquid around the heating element, and the atomized e-liquid is for users to inhale.

[0003] The heating element of the existing single-core dual-emission atomization core has a left-right structure of double mesh sheets, and the cross-section of the heating element is relatively large. Generally, the atomization core has a single air flow guiding hole opened at the center of the air inlet end, and the outside air flows through the single air flow guiding hole to the heating element. Thus, when the cross-section of the heating element is relatively large, the cross-section of the single air flow guiding hole of the atomization core also needs to be increased synchronously. In this way, it is difficult for the single air flow guiding hole to concentrate the outside air flow to the heating element or most of the air flow deviates from the heating element, resulting in the aerosol near the heating element being difficult to be effectively carried away, and further resulting in insufficient aerosol saturation and unsmooth air flow at the air outlet end of the electronic device, making the user experience poor.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0039] Please refer to Figures 1 to 9 , and now the atomizing core provided by the embodiment of the present application will be described. The atomizing core is applied to an electronic atomizing device. Among them, the electronic atomizing device can be used in different fields, such as medical atomization, electronic cigarette atomization, etc.

[0040] Please refer to Figure 1 and Figure 2, the atomizing core includes: an atomizing tube 10, a heating component 20 and a fixing seat 40. The atomizing tube 10 has an air inlet end 101 and an air outlet end 111 arranged opposite to each other. The heating component 20 is received in the atomizing tube 10. The heating component 20 includes a plurality of heating mesh sheets 21. The plurality of heating mesh sheets 21 are located at the air inlet end 101 and are distributed circumferentially along the atomizing tube 10. The fixing seat 40 is clamped and received at the air inlet end 101. The fixing seat 40 has a plurality of ventilation areas 41 distributed at intervals. The ventilation areas 41 communicate the air inlet end 101 and the air outlet end 111. Among them, the plurality of ventilation areas 41 are respectively arranged in one-to-one correspondence with the plurality of heating mesh sheets 21.

[0041] Among them, the inner wall of the atomizing tube 10 can permeate the liquid aerosol generating matrix to the heating mesh sheet 21. The aerosol generating matrix is heated and atomized by the energized heating of the heating mesh sheet 21 to generate aerosol. The generated aerosol flows out through the air outlet end 111 of the atomizing tube 10 for the user to consume. Among them, the aerosol generating matrix can be e-liquid, etc.

[0042] Compared with the prior art, for the atomizing core provided in this application, in the atomizing core of this application, by arranging the plurality of heating mesh sheets 21 of the heating component 20 at the air inlet end 101, and the fixing seat 40 is clamped and received at the air inlet end 101, and the plurality of ventilation areas 41 distributed at intervals on the fixing seat 40 are respectively arranged in one-to-one correspondence with the plurality of heating mesh sheets 21, so that the external air flow can flow uniformly and directly towards each heating mesh sheet 21 through the plurality of ventilation areas 41. Furthermore, the air flow blowing towards each heating mesh sheet 21 is larger and more concentrated, so that most of the aerosol near each heating mesh sheet 21 can be taken away fully and efficiently, making the aerosol at the air outlet end 111 more concentrated and full, and the air flow is smooth, which is beneficial to improving the user experience.

[0043] Optionally, there is an interval between two adjacent heating mesh sheets 21, and the shape of the atomizing tube 10 is adapted to the heating component 20. By arranging an interval between the two heating mesh sheets 21 to increase the distance between two adjacent heating mesh sheets 21, so that the plurality of heating mesh sheets 21 are in a state of being away from each other, which is beneficial to reducing the influence of thermal radiation between the heating mesh sheets 21, thus effectively avoiding the concentration of heat in the atomizing tube 10, and further being beneficial to reducing the temperature of the air outlet end 111 of the electronic atomizing device and improving the user experience. In addition, the shape of the atomizing tube 10 matches the heating component 20. In this way, the heating mesh sheet 21 can be completely and relatively stably attached to the inner wall of the atomizing tube 10, so that the plurality of heating mesh sheets 21 are stably kept in a state of being away from each other.

[0044] Optionally, the cross-sectional shape of the atomizer tube 10 is one of an ellipse, a rectangle, and a trapezoid, and the cross-sectional shape of the fixing seat 40 is consistent with the cross-sectional shape of the atomizer tube 10. The cross-sectional shape of the atomizer tube 10 refers to the cross-sectional shape obtained by cutting the atomizer tube 10 with a plane perpendicular to the axial direction of the atomizer tube 10, and the cross-sectional shape of the fixing seat 40 refers to the cross-sectional shape obtained by cutting the fixing seat 40 with a plane perpendicular to the axial direction of the atomizer tube 10.

[0045] In some embodiments of this application, please refer to Figure 2 and Figure 3 There are two heating meshes 21 , and the two heating meshes 21 are arranged opposite to each other at an interval; the fixing seat 40 has two ventilation areas 41 , and the two ventilation areas 41 are respectively arranged in a one-to-one correspondence with the two heating meshes 21 .

[0046] By setting the two ventilation areas 41 in one-to-one correspondence with the two heating meshes 21, the external airflow can flow evenly and directly to the two heating meshes 21 through the two ventilation areas 41, thereby making the airflow blowing to the two heating meshes 21 larger and more concentrated, so as to be able to take away a large amount of aerosol near the heating mesh 21.

[0047] Optionally, the cross section of the heating mesh 21 is U-shaped, the two heating meshes 21 are respectively fitted with the two narrow walls of the atomizing tube 10 , and the two ventilation areas 41 are respectively located on both sides of the fixing seat 40 in the width direction.

[0048] In other embodiments, the number of the heating meshes 21 may be three, four, or more, and the number of the ventilation areas 41 may be equal to the number of the heating meshes 21. For example, the number of the heating meshes 21 is three, and the three heating meshes 21 are evenly distributed around the center line of the atomizer tube 10. The number of the ventilation areas 41 is also three, and the three ventilation areas 41 are evenly distributed around the center line of the fixing base 40, and the three ventilation areas 41 are arranged in a one-to-one correspondence with the three heating meshes 21.

[0049] In some embodiments of this application, please refer to Figure 1 and Figure 3 Each ventilation area 41 is provided with at least one airflow guide hole 410 , and the airflow guide hole 410 is configured so that the airflow passing through the airflow guide hole 410 can impact the heating mesh 21 corresponding to the ventilation area 41 where the airflow guide hole 410 is located.

[0050] It can be understood that since there are multiple ventilation areas 41, there are also multiple airflow guide holes 410 on the fixing seat 40, and the airflow flowing through the airflow guide holes 410 on each ventilation area 41 can flow directly toward the heating mesh 21 corresponding to the ventilation area 41.

[0051] When a plurality of heating mesh sheets 21 of the heating component 20 are circumferentially distributed along the atomizing tube 10, by opening air flow guiding holes 410 in the area of the fixing seat 40 corresponding to the heating mesh sheets 21, the outside air flow passes through the air flow guiding holes 410 and concentrates on the corresponding heating mesh sheets 21, so that the air flow near the heating mesh sheets 21 is larger, thereby being able to fully and effectively take away the aerosol near the heating mesh sheets 21. At the same time, since the air flow guiding holes 410 are only opened at the positions of the fixing seat 40 corresponding to the heating mesh sheets 21, compared with a single air flow guiding hole 410 in the prior art, it is beneficial to reduce the cross-section of the air flow guiding holes 410 on the fixing seat 40, thereby effectively preventing the air flow flowing out from the air flow guiding holes 410 from deviating from the heating mesh sheets 21.

[0052] In some embodiments of the present application, please refer to Figure 2 and Figure 3 , the number of the heating mesh sheets 21 is two, and the number of the ventilation areas 41 is also two, and they are respectively arranged in one-to-one correspondence with the two heating mesh sheets 21. Each ventilation area 41 is provided with an air flow guiding hole 410, so as to form double air flow guiding holes 410 on the fixing seat 40. It can be understood that when the number of the heating mesh sheets 21 is two, by opening double air flow guiding holes 410 on the fixing seat 40, the outside air flow passes through the double air flow guiding holes 410 and concentrates on the corresponding heating mesh sheets 21, so that the air flow near the heating mesh sheets 21 is larger, thereby being able to fully and effectively take away the aerosol near the heating mesh sheets 21.

[0053] In some embodiments of the present application, please refer to Figure 4 and Figure 5 , the number of the heating mesh sheets 21 is two, and the number of the ventilation areas 41 is also two, and they are respectively arranged in one-to-one correspondence with the two heating mesh sheets 21. One air flow guiding hole 410 is provided on each ventilation area 41. The fixing seat 40 further has an intermediate area 42, and the intermediate area 42 is arranged between the two ventilation areas 41. The intermediate area 42 is provided with a flow channel 420, and the flow channel 420 of the intermediate area 42 is respectively communicated with the two air flow guiding holes 410 of the two ventilation areas 41 to form a narrow strip-shaped channel. The outside air flow flows to each heating mesh sheet 21 through the narrow strip-shaped channel, effectively increasing the contact area between the air flow and each heating mesh sheet 21, thereby being able to fully and effectively take away the aerosol near the heating mesh sheets 21.

[0054] In some embodiments of the present application, please refer to Figure 6 and Figure 7Each ventilation area 41 is provided with a plurality of airflow guide holes 410 spaced apart. By providing a plurality of airflow guide holes 410 spaced apart in each ventilation area 41, the external airflow is blown more evenly through the plurality of airflow guide holes 410 in the ventilation area 41 to the corresponding respective areas of the half-waist-shaped heating mesh 21, thereby fully and effectively removing the aerosol near the heating mesh 21.

[0055] In some embodiments of the present application, the centerline of the airflow guide hole 410 forms an acute angle with the axial direction of the atomizer tube 10. It is understandable that when the external airflow flows through the airflow guide hole 410 toward the heating mesh 21, the airflow gradually deviates from the axial direction of the atomizer tube 10, causing the airflow to gradually deviate toward the corresponding heating mesh 21, so that the airflow flows directly toward the corresponding heating mesh 21.

[0056] In some embodiments of the present application, the inner diameter of the airflow guide hole 410 gradually decreases from an end of the fixing base 40 away from the heating element to an end of the fixing base 40 close to the heating element.

[0057] Since the inner diameter of the airflow guide hole 410 gradually decreases from the end of the fixing base 40 away from the heating element to the end of the fixing base 40 close to the heating element, when the external airflow passes through the airflow guide hole 410, the airflow gradually concentrates and the pressure gradually increases, so that the airflow intensity blowing toward the heating mesh 21 is greater, and the aerosol near the heating mesh 21 can be more effectively taken away.

[0058] Optionally, the airflow guide hole 410 may be, but is not limited to, a conical airflow guide hole 410 , a trapezoidal airflow guide hole 410 , or the like.

[0059] In some embodiments of this application, please refer to Figure 1 The atomization core also includes an electrode assembly 30, which is electrically connected to each heating mesh 21. The electrode assembly 30 is used to electrically connect each heating mesh 21 with a power supply assembly of the electronic atomization device, so that the power supply assembly supplies power to the heating mesh 21 through the electrode assembly 30.

[0060] Specifically, see Figure 8 The electrode assembly 30 includes a first electrode pin 31 and a second electrode pin 32. The first electrode pin 31 is electrically connected between two adjacent heating meshes 21 and is electrically connected to the two adjacent heating meshes 21 at the same time. The second electrode pin 32 is electrically connected to the end of the heating mesh 21 away from the first electrode pin 31.

[0061] Optionally, the first electrode pin 31 is a positive electrode pin, and the second electrode pin 32 is a negative electrode pin. Alternatively, the first electrode pin 31 is a negative electrode pin, and the second electrode pin 32 is a positive electrode pin.

[0062] By electrically connecting the first electrode pin 31 to two adjacent heating mesh sheets 21, the two adjacent heating mesh sheets 21 share one first electrode pin 31, which helps reduce the number of first electrode pins 31, simplifies the structure, and makes the performance of the atomization core more stable and reliable.

[0063] Optionally, the number of second electrode pins 32 is equal to the number of heating mesh sheets 21. For example, when the number of heating mesh sheets 21 is two, the number of second electrode pins 32 is also two, and the two electrode pins 32 are respectively electrically connected to one end of the heating mesh sheet 21 far from the first electrode pin 31.

[0064] By respectively electrically connecting multiple second electrode pins 32 to multiple heating mesh sheets 21 one by one, the heating conditions of each heating mesh sheet 21 can be individually controlled by separately controlling the on / off of each second electrode pin 32. In this way, the heating power of the heating component 20 can be adjusted according to requirements. For example, when the temperature of the air outlet end 111 is too high, part of the heating mesh sheets 21 can be energized to generate heat, and the other part of the heating mesh sheets 21 can be powered off to reduce the heating power of the entire heating component 20, thereby reducing the temperature of the air outlet end 111.

[0065] A plurality of card slots 43 are provided on the outer peripheral side wall of the fixing seat 40, and the first electrode pin 31 and the plurality of second electrode pins 32 are respectively and separately clamped in different card slots 43.

[0066] Since the lengths of the first electrode pin 31 and the second electrode pin 32 are relatively long, the first electrode pin 31 and the second electrode pin 32 are separately limited by the plurality of card slots 43, effectively preventing the multiple electrode pins from being wound around each other and causing unstable electrical connection between the heating mesh sheet 21 and the power supply component.

[0067] It should be noted that the number of second electrode pins 32 is the same as the number of heating mesh sheets 21. For example, when the number of heating mesh sheets 21 is two, the number of second electrode pins 32 is also two, and the two second electrode pins 32 are respectively electrically connected to the other sides of the two heating mesh sheets 21.

[0068] In some embodiments of the present application, please refer to Figure 1 and Figure 2 , the atomization tube 10 further includes a tube body 11 and an oil guide cotton 12 received in the tube body 11, and the oil guide cotton is clamped between the tube body and the heating mesh sheet.

[0069] The oil guide cotton 12 is annular and fits on the circumferential inner wall of the atomization tube 10.

[0070] The oil-conducting cotton 12 is used to infiltrate the adsorbed liquid aerosol production matrix onto the heating mesh 21. Optionally, the oil-conducting cotton 12 can be made of soft fiber materials such as cotton fiber, non-woven fabric, and blended fibers. The oil-conducting cotton 12 has excellent oil absorption performance and is less prone to oil leakage, resulting in a full and authentic vapor. The oil-conducting cotton 12 heats quickly, requiring no preheating before use, and produces a richer first puff of vapor. Furthermore, the material cost of the oil-conducting cotton 12 is relatively low, which helps reduce the production cost of the atomizer core.

[0071] In some embodiments of this application, please refer to Figure 1 and Figure 2 The tube body 11 is made of either metal or plastic. Metal tubes are structurally stable and less prone to deformation. Plastic tubes are lightweight and low-cost, which helps reduce the weight of the atomizer core and lowers its manufacturing cost.

[0072] In some embodiments of this application, please refer to Figure 9 The tube body 11 is a plastic tube body, and the fixing seat 40 is a plastic part, and is integrally formed with the tube body 11. By using a plastic part and integrally forming the fixing seat 40 with the tube body 11, the fixing seat 40 and the tube body 11 are integrated, which helps to reduce the number of parts of the atomizer core, making the overall structure of the atomizer core more stable, and facilitating processing and assembly, which helps to reduce the manufacturing cost of the atomizer core.

[0073] An embodiment of the present application also provides an electronic atomization device, comprising: a shell, a power supply assembly housed in the shell, and an atomizer core according to any of the above embodiments, wherein the atomizer core is housed in the shell, and the power supply assembly is used to power the atomizer core.

[0074] The electronic atomizer provided in the present application adopts the above-mentioned atomizer core. The above-mentioned atomizer core is achieved by arranging multiple heating meshes 21 of the heating component 20 at the air inlet end 101, and the fixing seat 40 is clamped and accommodated in the air inlet end 101, and the multiple spaced ventilation areas 41 on the fixing seat 40 are respectively arranged in one-to-one correspondence with the multiple heating meshes 21, so that the external airflow can flow evenly and directly to each heating mesh 21 through the multiple ventilation areas 41, thereby making the airflow blowing to each heating mesh 21 larger and more concentrated, so that most of the aerosol near each heating mesh 21 can be fully and efficiently taken away, so that the aerosol at the air outlet end 111 is more concentrated and full, and the airflow is smooth, which is conducive to improving the user experience.

[0075] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
