Description

Technical Field

[0002] Electronic atomizers are also known as virtual cigarettes, steam cigarettes, electronic cigarettes, aerosol generating devices, etc. They are mainly used to simulate the feeling of smoking without affecting health, so as to help people quit smoking or replace cigarettes. The atomizer core is one of the important components of the electronic atomizer, which is used to heat the atomized oil to generate smoke for users to inhale.

[0003] The atomizer core generally includes a porous ceramic substrate and a heating substrate arranged on the porous ceramic substrate. The heating substrate heats the porous ceramic substrate by direct contact, so that the tobacco oil in the porous ceramic substrate is heated and atomized to form an aerosol. In order to improve the heating power of the heating substrate, the heating substrate in some atomizer cores currently adopts a structure in which multiple heating units are connected in parallel (for details, please refer to patents such as CN220068888U). However, the following problems are found in the use of this type of atomizer core: Since the interval between adjacent heating units is relatively close, when multiple heating units work at the same time, the aerosols generated on the adjacent heating units will collide with each other and condense into large particles, making the aerosol particles more easily condensed and liquefied, thereby increasing the condensate, affecting the suction taste, and reducing the utilization rate of the tobacco oil; at the same time, since the heating unit generates noise when heating and atomizing the tobacco oil (the noise is mainly the sound generated when the tobacco oil boils and evaporates), when multiple heating units work at the same time, a greater noise will be generated, and the noise generated by the multiple heating units will resonate and interfere with each other, thereby further increasing the decibel of the noise, affecting the user's experience.

The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] The directional words such as up, down, left, right, front, back, top, bottom, etc. (if any) involved in the specification and claims of the utility model are defined by the positions of the structures in the drawings and the positions of the structures relative to each other, and are only for the clarity and convenience of expressing the technical solution. It should be understood that the use of directional words should not limit the scope of protection claimed by the utility model.

[0028] like Figures 1 to 6 As shown, the atomizer core provided by the embodiment of the utility model is used in an electronic atomizer. The atomizer core includes a porous substrate 1 and a heating element 2 arranged on the surface of the porous substrate 1. The porous substrate 1 is a porous structure (i.e., a plurality of micropores are arranged in the porous substrate 1); the porous substrate 1 can be specifically porous ceramic or porous glass. The heating element 2 includes a plurality of heating parts 21 arranged at intervals, and the heating part 21 is used to generate heat after power is turned on to heat and atomize the atomized liquid (such as smoke oil).

[0029] A protrusion 11 is provided on the surface of the porous substrate 1 on the side close to the heating element 2, the protrusion 11 is fixedly connected to the porous substrate 1, and the protrusion 11 extends outward from the heating element 2 toward the side away from the porous substrate 1. The protrusion 11 includes a barrier 110, which is located between adjacent heating elements 21, and the barrier 110 separates adjacent heating elements 21.

[0030] The atomizer core provided by the embodiment of the utility model is provided with a protrusion 11 on the porous substrate 1. The protrusion 11 protrudes outward compared with the heating element 2. The protrusion 11 includes a baffle 110. The baffle 110 is located between each adjacent heating element 21. On the one hand, the baffle 110 can separate each adjacent heating element 21, thereby reducing the mutual interference between adjacent heating elements 21 during operation, that is, reducing the probability of aerosols generated on adjacent heating elements 21 colliding with each other and condensing into large particles, thereby reducing the generation of condensed liquid and improving the utilization rate of atomized liquid; at the same time, the baffle 110 can also reflect and absorb the atomization noise generated when the heating element 21 is working, thereby reducing the decibel of the atomization noise (that is, the baffle 110 is equivalent to the role of a wall, which can both separate adjacent heating elements 21 and reflect and absorb the atomization noise), thereby improving the user experience.

[0031] like Figures 3 to 6 As shown, as an embodiment, the protrusion 11 also includes a pressure edge portion 113 connected to the baffle portion 110, the pressure edge portion 113 is arranged corresponding to the edge of the heating element 2, and the pressure edge portion 113 is an annular structure surrounding the edge of the heating element 2, and the edge of the heating element 2 is sandwiched between the pressure edge portion 113 and the porous matrix 1. At the same time, the pressure edge portion 113, the baffle portion 110 and the porous matrix 1 enclose a plurality of mutually independent separation chambers 10, and the plurality of separation chambers 10 correspond to the plurality of heating portions 21 respectively, and each heating portion 21 is located in a corresponding separation chamber 10.

[0032] Specifically, by setting the edge pressing portion 113, the edge pressing portion 113 is set corresponding to the edge of the heating element 2. On the one hand, the edge pressing portion 113 can press the edge position of the heating element 2 so that the heating element 2 remains in close contact with the surface of the porous matrix 1, thereby preventing problems such as burnt smell and carbon deposition caused by the non-contact between the heating element 2 and the surface of the porous matrix 1 (if the heating element 2 and the surface of the porous matrix 1 are not in contact, the heating element 2 is prone to insufficient oil supply, causing the heating element 2 to burn dry, which is prone to problems such as burnt smell and carbon deposition); on the other hand, the edge pressing portion 113 can cooperate with the baffle portion 110 and the porous matrix 1 to form a plurality of partition chambers 10, and each heating part 21 is located in the corresponding partition chamber 10 (that is, a plurality of independent grids are formed, and each heating part 21 is respectively located in each grid), so as to better separate each heating part 21, so as to further reduce the generation of condensate, and at the same time, it can better reflect and absorb the atomization noise, so as to further reduce the decibel of the atomization noise.

[0033] like Figure 3 and Figure 4 As shown in FIG. 1 , as an embodiment, the side edge of the heating portion 21 is sandwiched between the barrier portion 110 and the porous substrate 1 ( Figure 4The solid lines in the figure represent visible parts, and the dotted lines represent obstructed invisible parts). Specifically, the porous matrix 1 has a first direction X, which is perpendicular to the extension direction of the heating portion 21 (that is, the length direction of the heating portion 21), and at least part of the heating portions 21 are arranged in intervals along the first direction X; each side of two heating portions 21 arranged adjacent to each other along the first direction X is sandwiched between the barrier portion 110 and the porous matrix 1 (that is, the width of the barrier portion 110 is greater than the spacing between two adjacent heating portions 21, and the barrier portion 110 covers the side position of the heating portion 21). In other words, in addition to being able to separate adjacent heating portions 21, the barrier portion 110 can also press the heating portion 21 to further improve the tightness of the fit between the heating body 2 and the porous matrix 1.

[0034] like Figures 3 to 6 As shown, as an embodiment, the porous matrix 1 has a first direction X and a second direction Y perpendicular to each other, each heat generating portion 21 is extended along the second direction Y, and a plurality of heat generating portions 21 are arranged in an array along the first direction X and the second direction Y. The barrier portion 110 includes a first barrier bar 111 and a second barrier bar 112 arranged perpendicularly and crosswise to each other, the first barrier bar 111 is extended along the first direction X, and the first barrier bar 111 is located between the heat generating portions 21 arranged adjacently along the second direction Y; the second barrier bar 112 is extended along the second direction Y, and the second barrier bar 112 is located between the heat generating portions 21 arranged adjacently along the first direction X.

[0035] like Figures 1 to 4 As shown in the figure, as an embodiment, the porous matrix 1 is a rectangular parallelepiped structure, the first direction X is the width direction of the porous matrix 1, and the second direction Y is the length direction of the porous matrix 1. Of course, in other embodiments, the first direction X can also be the length direction of the porous matrix 1, and the second direction Y can be the width direction of the porous matrix 1.

[0036] like Figure 3 and Figure 4 As shown, as an embodiment, the sides of the two heating parts 21 adjacent to each other along the first direction X are sandwiched between the second barrier strip 112 and the porous matrix 1. At the same time, the other side of the heating part 21 is sandwiched between the edge pressing part 113 and the porous matrix 1, so that both sides of the heating part 21 are pressed by the protrusion 11 to improve the tightness of the fitting between the heating body 2 and the porous matrix 1.

[0037] like Figures 3 to 6As shown, as an embodiment, a plurality of heating parts 21 are arranged in two rows along the second direction Y. The heating body 2 also includes a total collecting part 22 and a plurality of sub-collecting parts 23 arranged at intervals. The total collecting part 22 is arranged to extend along the first direction X. The total collecting part 22 corresponds to the first baffle bar 111. The total collecting part 22 and the first baffle bar 111 are both located between the two rows of heating parts 21. One end of each heating part 21 is connected to the total collecting part 22, and the other end of each heating part 21 is provided with a sub-collecting part 23, that is, each heating part 21 is connected in parallel. The total collecting part 22 is sandwiched between the first baffle bar 111 and the porous matrix 1, and the sub-collecting part 23 is sandwiched between the edge pressing part 113 and the porous matrix 1.

[0038] Specifically, the total current collecting part 22 is used to connect to one of the positive and negative poles of the power supply (for example, the positive pole), and each sub-current collecting part 23 is used to connect to the other pole (for example, the negative pole) of the positive and negative poles of the power supply, so as to realize the parallel connection of each heating part 21. Multiple heating parts 21 can work separately or simultaneously. By controlling the number of heating parts 21 connected to the circuit, the atomization amount of the atomization core can be freely switched, and at the same time, the same heating part 21 can be prevented from working for a long time, reducing the generation of carbon deposits, ensuring the atomization taste, and extending the service life of the atomization core. Moreover, the heating element 2 adopts an orderly arrangement structure, so that each heating part 21 can share the same total current collecting part 22, which not only facilitates circuit connection and circuit control, but also reduces the setting area of ​​the current collecting part, which is conducive to increasing the setting area and coverage area of ​​the heating part 21, thereby improving the atomization area and heating efficiency.

[0039] like Figure 3 and Figure 4 As shown, as an embodiment, the width of the first barrier strip 111 is smaller than the width of the total current collecting part 22, the first barrier strip 111 only covers a portion of the total current collecting part 22, and another portion of the total current collecting part 22 is exposed outside the first barrier strip 111; the width of the edge pressing part 113 is smaller than the width of the sub-current collecting part 23, the edge pressing part 113 only covers a portion of the sub-current collecting part 23, and another portion of the sub-current collecting part 23 is exposed outside the edge pressing part 113. The exposed portion of the total current collecting part 22 and the exposed portion of the sub-current collecting part 23 can be connected to the positive and negative electrodes of the power supply through electrode rods (not shown).

[0040] like Figure 3 , Figure 4 and Figure 6As shown, as an embodiment, the number of the heating parts 21 is four, and the four heating parts 21 are arranged in two rows and two columns along the first direction X and the second direction Y. The first baffle bar 111 and the second baffle bar 112 cross each other perpendicularly to form a "cross" shaped structure, and the edge clamping part 113 is a "mouth" shaped structure arranged around the edge of the porous matrix 1. The opposite ends of the first baffle bar 111 are respectively connected to two of the side edges of the edge clamping part 113, and the opposite ends of the second baffle bar 112 are respectively connected to the other two side edges of the edge clamping part 113, and the raised part 11 is in a "field" shaped structure as a whole. Four partition cavities 10 are enclosed by the edge clamping part 113, the baffle part 110 and the porous matrix 1, and the four heating parts 21 are respectively located in the four partition cavities 10. As shown Figure 7 As shown in the figure, as another embodiment, the number of the heating parts 21 is six, and the six heating parts 21 are arranged in three rows and two columns along the first direction X and the second direction Y. Of course, in other embodiments, the number of the heating parts 21 can also be two or more (when the number of the heating parts 21 is two, the two heating parts 21 can be arranged alternately along the first direction X or the second direction Y).

[0041] As an embodiment, the resistance values ​​of all the heating parts 21 are the same, that is, the heating parts 21 have the same heating effect. As another embodiment, at least some of the heating parts 21 have different resistance values. When the resistance values ​​of the heating parts 21 are different, they have different heating powers (because the heating parts 21 are connected in parallel, according to the formula P = U 2 / R, the larger the resistance, the smaller the heating power), the corresponding atomization amount is different, and the atomization effect is also different.

[0042] like Figure 5 As shown, as an embodiment, the height H of the protrusion 11 protruding from the surface of the heating element 2 is 0.3 mm to 1.0 mm, so that the protrusion 11 has a good effect of blocking and reflecting / absorbing atomization noise.

[0043] like Figure 6 As shown, as an embodiment, a plurality of hooks 24 are provided on the heating element 2 (specifically, hooks 24 are provided on the total collecting portion 22, the sub-collecting portion 23 and the heating portion 21), and the hooks 24 are embedded in the porous matrix 1 to further improve the bonding tightness between the heating element 2 and the porous matrix 1.

[0044] like Figure 2 and Figure 5As shown, as an embodiment, the heating element 2 is arranged on the bottom surface of the porous substrate 1, and a liquid storage tank 12 for temporarily storing the atomized liquid is arranged on the top surface of the porous substrate 1; the heating portion 21 can heat and atomize the atomized liquid in the liquid storage tank 12. Specifically, in this embodiment, there are two liquid storage tanks 12, and the two liquid storage tanks 12 are respectively arranged corresponding to two rows of heating portions 21.

[0045] As another embodiment, there are multiple liquid storage tanks 12, and the multiple liquid storage tanks 12 correspond to the multiple heating parts 21 one by one. The liquid storage tanks 12 are arranged at intervals from each other, so that each heating part 21 can heat and atomize the atomized liquid in the corresponding liquid storage tank 12 respectively.

[0046] Meanwhile, when the resistance values ​​of the heating parts 21 are the same, the volumes of the liquid storage tanks 12 are the same. When the resistance values ​​of at least some of the heating parts 21 are different, among the two heating parts 21 with different resistance values, the volume of the liquid storage tank 12 corresponding to the heating part 21 with a smaller resistance value is greater than the volume of the liquid storage tank 12 corresponding to the heating part 21 with a larger resistance value.

[0047] Specifically, since the heating power of the heating part 21 with a small resistance value is greater than the heating power of the heating part 21 with a large resistance value, the volume of the liquid storage tank 12 corresponding to the heating part 21 with a small resistance value is set larger, so that the liquid storage capacity of the liquid storage tank 12 matches the power of the heating part 21, thereby meeting the oil supply requirements of the heating parts 21 with different powers (the greater the heating power of the heating part 21, the faster the rate at which it consumes the tobacco oil, and the greater the oil supply requirement). In order to make the volume of the liquid storage tank 12 different, the volume of the liquid storage tank 12 can be adjusted by changing the cross-sectional area, depth and other dimensions of the liquid storage tank 12.

[0048] like Figure 5 As shown, as an embodiment, in the direction from the notch 121 of the liquid storage tank 12 to the bottom 122 of the liquid storage tank 12 (i.e., from top to bottom), the cross section of the liquid storage tank 12 is an inverted trapezoidal structure with a gradually decreasing width. Such a configuration is conducive to increasing the volume of the liquid storage tank 12 on the one hand, and on the other hand, it can make the atomized liquid flow downward along the inner wall of the liquid storage tank 12 more smoothly, reducing the adhesion of the atomized liquid on the inner wall of the liquid storage tank 12.

[0049] like Figure 6 As shown, as an embodiment, all the heating parts 21 have the same structure, and all the heating parts 21 are heating nets. Of course, in other embodiments, all the heating parts 21 can also be heating wires, etc. As another embodiment, among all the heating parts 21, at least some of the heating parts 21 have different structures; for example, some of the heating parts 21 are heating nets, and other parts of the heating parts 21 are heating wires.

[0050] As an embodiment, the thickness of the heating element 2 is 0.05 mm to 0.12 mm, and the heating element 2 can be made by stamping or etching. The heating element 2 can be made of metal materials such as stainless steel (such as 310 stainless steel, 316 stainless steel, etc.), titanium, chromium, nickel-chromium, iron-chromium-aluminum, etc.

[0051] As an implementation mode, the protrusion 11 is made of insulating material to avoid affecting the conductive heating function of the heating element 2 .

[0052] As an embodiment, the raised portion 11 is a porous structure (i.e., a plurality of micropores are provided in the raised portion 11), so that the raised portion 11 can better absorb and reflect the sound (i.e., atomization noise) generated when the heating portion 21 heats and atomizes the atomized liquid. Specifically, since the raised portion 11 is a porous structure, the atomization noise can be reflected multiple times on the surface of the raised portion 11 (the surface of the raised portion 11 is an uneven structure) and absorbed into the pores in the raised portion 11, thereby achieving a better silencing effect.

[0053] As an embodiment, the protrusion 11 is made of the same material as the porous substrate 1, and the protrusion 11 is connected to the porous substrate 1 as an integral structure. Specifically, the protrusion 11 is fixedly connected to a position on the porous substrate 1 that is not covered by the heating element 2 (specifically, in this embodiment, the porous substrate 1 is not covered by the heating element 2 on both sides of the heating element 2 along the first direction X and between two heating elements 21 arranged adjacently along the first direction X, and the protrusion 11 is fixedly connected to this position).

[0054] Specifically, in this embodiment, the porous matrix 1 is a porous ceramic body, and the raised portion 11 is also made of porous ceramic material. During production, the manufactured heating element 2 is fixedly placed on the mold, and the heating element 2 and the ceramic slurry are fixed together by hot die casting. The ceramic green body is obtained by cooling, solidifying and demolding, and then the atomizing core can be obtained through steps such as debinding and sintering; wherein, ceramic slurry is provided on both sides of the heating element 2, and the ceramic slurries on the two sides are respectively used to form the porous matrix 1 and the raised portion 11, and the ceramic slurries on the two sides are in contact with each other and connected as a whole after high-temperature sintering.

[0055] This embodiment also provides an electronic atomizer, including the above-mentioned atomization core.

[0056] The atomizer core provided in this embodiment is provided with a protrusion 11 on the porous substrate 1. The protrusion 11 protrudes outward compared to the heating element 2. The protrusion 11 includes a baffle 110. The baffle 110 is located between each adjacent heating element 21. On the one hand, the baffle 110 can separate each adjacent heating element 21, thereby reducing the mutual interference between adjacent heating elements 21 during operation, that is, reducing the probability of aerosols generated on adjacent heating elements 21 colliding with each other and condensing into large particles, thereby reducing the generation of condensed liquid and improving the utilization rate of atomized liquid; at the same time, the baffle 110 can also reflect and absorb the atomization noise generated when the heating element 21 is working, thereby reducing the decibel of the atomization noise and improving the user experience.

[0057] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
