Description

电子雾化装置及其雾化器和雾化芯Electronic atomization device and its atomizer and atomization core 技术领域technical field
本发明涉及一种雾化装置，更具体地说，涉及一种电子雾化装置及其雾化器和雾化芯。The present invention relates to an atomizing device, more specifically, to an electronic atomizing device and its atomizer and atomizing core.
背景技术Background technique
相关技术中的用于吸食气溶胶的电子雾化装置包括陶瓷雾化芯，雾化芯包括用于吸液的陶瓷多孔体以及结合于该陶瓷多孔体表面用于加热雾化的加热元件。An electronic atomization device for inhaling aerosol in the related art includes a ceramic atomizing core, and the atomizing core includes a ceramic porous body for liquid absorption and a heating element combined on the surface of the ceramic porous body for heating atomization.
目前已有的陶瓷雾化芯一般通过嵌入发热丝、发热片或印制发热膜的方式来对进行加热。在现有的技术中，无论是发热丝还是发热膜，其导电轨迹和发热轨迹是一致的，这表明一整条轨迹都在产生热量，且只能向两边传递，造成发热轨迹的局部高温，进一步产生有害物质或造成发热膜的失效。The existing ceramic atomizing cores are generally heated by embedding heating wires, heating sheets or printing heating films. In the existing technology, whether it is a heating wire or a heating film, the conductive track and the heating track are consistent, which means that the whole track is generating heat, and it can only be transmitted to both sides, resulting in local high temperature of the heating track. Further produce harmful substances or cause the failure of the heating film.
另一方面，也可以通过增大发热膜的方式来控制局部高温。比如印制一整个面的发热膜，使整个表面都能导电且均匀发热，从而使温度分布更加均匀。但这种方案的缺点是发热面过大，降低了热流密度，使发热膜升温速率减慢，增加了等待升温雾化的时间，也会影响使用者的口感体验。On the other hand, the local high temperature can also be controlled by increasing the heating film. For example, a heating film is printed on the entire surface, so that the entire surface can conduct electricity and heat evenly, so that the temperature distribution is more uniform. However, the disadvantage of this solution is that the heating surface is too large, which reduces the heat flux density, slows down the heating rate of the heating film, increases the waiting time for heating and atomization, and also affects the user's taste experience.

上述实施例中的雾化芯12v的加热元件121v在一定程度上能够满足电子雾化装置的发热需求，然而，由于加热元件121v的发热部1223v呈长条状，且发热部1223v在整个长度上均发热，从平面上来看，发热部1223v中某一位点的左右方向都具有接近的热流密度，所以热量不能向左右传导，只能向上下两个方向传导（如图10的箭头所示），所以容易在局部积蓄热量，达到过热状态（如图11所示）。The heating element 121v of the atomizing core 12v in the above embodiment can meet the heating requirements of the electronic atomization device to a certain extent. However, since the heating part 1223v of the heating element 121v is in the shape of a long strip, and the heating part 1223v extends over the entire length From the perspective of the plane, the left and right directions of a certain point in the heating part 1223v have close heat flux density, so the heat cannot be conducted to the left and right, but can only be conducted in the upward and downward directions (as shown by the arrow in Figure 10) , so it is easy to accumulate heat locally and reach an overheated state (as shown in Figure 11).
在一些实施例击中，为了使整个雾化面的温度更均匀，将整个面都印制发热膜从而形成面式发热轨迹，这种面式发热轨迹虽然具有发热面的温度均匀一致的特点，但也具有一定的劣势。为了使整个雾化面都能均匀发热，所以发热面必须很大，这就造成其热流密度变低。低热流密度会造成加热速率变慢，长时间不能达到液态气溶胶生成基质所需的雾化温度，从而导致响应变慢、气溶胶不足和口感变差。In some embodiments, in order to make the temperature of the entire atomization surface more uniform, a heating film is printed on the entire surface to form a surface heating track. Although this surface heating track has the characteristics of uniform temperature on the heating surface, But it also has certain disadvantages. In order to make the entire atomization surface heat evenly, the heating surface must be large, which results in a low heat flux density. Low heat flux will result in a slower heating rate, and the atomization temperature required for the liquid aerosol-generating substrate cannot be reached for a long time, resulting in slower response, insufficient aerosol and poor taste.
图12示出了本发明另一些实施例中的雾化芯12，该雾化芯12可作为上述雾化芯12v的一个替代，并可以解决上述雾化芯12v的热量局部积蓄的问题。如图12所示，该雾化芯12可包括多孔体121以及设置于多孔体121底面的加热元件122。多孔体121在一些实施例中可包括烧结式多孔陶瓷体，用于吸取液态气溶胶生成基质。该加热元件122在一些实施例中可为以镍铬合金为发热材料的发热膜，该发热膜可采用印刷的方式形成于多孔体121的表面，其厚度可为100μm。该加热元件122在一些实施例中还包括用于与第一电极引线相连接的第一电极连接部1221、用于第二电极引线相连接的第二电极连接部1222以及连接于该第一电极连接部1221和第二电极连接部1222之间的发热部1223。Fig. 12 shows the atomization core 12 in some other embodiments of the present invention, the atomization core 12 can be used as a replacement of the above-mentioned atomization core 12v, and can solve the problem of local heat accumulation of the above-mentioned atomization core 12v. As shown in FIG. 12 , the atomizing core 12 may include a porous body 121 and a heating element 122 disposed on the bottom surface of the porous body 121 . Porous body 121 may comprise a sintered porous ceramic body in some embodiments for absorbing a liquid aerosol-generating substrate. In some embodiments, the heating element 122 can be a heating film with nickel-chromium alloy as the heating material, and the heating film can be formed on the surface of the porous body 121 by printing, and its thickness can be 100 μm. In some embodiments, the heating element 122 also includes a first electrode connection part 1221 for connecting to a first electrode lead, a second electrode connection part 1222 for connecting a second electrode lead, and a second electrode connection part 1222 connected to the first electrode lead. The heating part 1223 between the connecting part 1221 and the second electrode connecting part 1222 .
发热部1223在一些实施例中包括若干平行间隔布置的发热带，每一发热带包括交替布置的若干线型部位和若干圆型部位，线型部位形成连接圆型部位的节点。线型部位的线宽可为200μm，圆型部位的半径可为400μm。由于线宽的差别，所以电阻都集中在线宽较窄的节点（线型部位）处，线型部位形成电阻较大的发热单元1223a，圆型部位形成电阻较小的导电单元1223b。各节点在横向和纵向的距离是等间距的，所以可以形成点阵式的发热轨迹分布。可以理解地，在一些实施例中，发热膜的厚度可为80-120μm，线型部位的线宽可为180-220μm，圆型部位的半径可为380-420μm。In some embodiments, the heating part 1223 includes several heating bands arranged in parallel and at intervals, each heating band includes several linear parts and several circular parts alternately arranged, and the linear parts form nodes connecting the circular parts. The line width of the linear portion may be 200 μm, and the radius of the circular portion may be 400 μm. Due to the difference in line width, the resistances are concentrated at nodes with narrower line widths (line-shaped parts). The line-shaped parts form heating units 1223a with higher resistance, and the circular parts form conductive units 1223b with lower resistance. The horizontal and vertical distances of each node are equally spaced, so a dot-matrix heating track distribution can be formed. Understandably, in some embodiments, the thickness of the heating film may be 80-120 μm, the line width of the linear portion may be 180-220 μm, and the radius of the circular portion may be 380-420 μm.
如图13所示，从平面上来看热量可以向四个方向扩散。于此，通过调整发热点（发热单元1223a）的间距，使每个发热点的热影响区相互重叠，则既可以形成一整片温度相对均匀的高温区域，很好地解决了由于热量的积聚而形成过热状态。在一些实施例中，每相邻两个发热点的距离可设置在0.2-5mm之间。As shown in Figure 13, heat can spread in four directions when viewed from a plane. Here, by adjusting the spacing of the heating points (heating unit 1223a) so that the heat-affected zones of each heating point overlap each other, a whole high-temperature area with relatively uniform temperature can be formed, which solves the problem of heat accumulation due to heat accumulation. resulting in overheating. In some embodiments, the distance between every two adjacent heating points can be set between 0.2-5mm.
对该加热元件122的发热特性进行模拟仿真，施加6.5W的直流电后，加热元件122会快速升温，考虑到加热元件122本身和向陶瓷基体的导热过程后，得到3s时的温度分布如图14所示。仿真结果与预期一致，主要的发热点与主要的发热区域都集中在每两个圆型部位交接的节点处，产生的热量有向四个方向传导的趋势。同时各个发热点温度接近一致，间距均匀，形成了点阵式发热轨迹。可以理解地，虽然图示的发热点呈矩形阵列排布，但并不局限于此，在一些实施例中，发热点也可以呈圆形阵列布置，或者其他非规则阵列布置。由此可知，点阵式雾化轨迹的设计既可以使发热点的温度快速升高，实现液态气溶胶生成基质的快速雾化，又能向多个方向传导热量，防止热量的积聚和过热状态的发生。可以理解地，加热元件122并不局限于是发热膜，其也可以是发热丝、发热片等其他适合的加热元件。The heating characteristics of the heating element 122 are simulated. After applying 6.5W of direct current, the heating element 122 will heat up rapidly. After considering the heating element 122 itself and the heat conduction process to the ceramic substrate, the temperature distribution at 3s is obtained as shown in Figure 14 shown. The simulation results are consistent with expectations. The main heating points and areas are concentrated at the junction of every two circular parts, and the generated heat tends to conduct in four directions. At the same time, the temperature of each heating point is close to the same, and the spacing is uniform, forming a lattice heating track. It can be understood that although the illustrated heating points are arranged in a rectangular array, it is not limited thereto. In some embodiments, the heating points may also be arranged in a circular array or other irregular arrays. It can be seen that the design of the dot-matrix atomization trajectory can not only increase the temperature of the heating point quickly, realize the rapid atomization of the liquid aerosol-generating substrate, but also conduct heat to multiple directions to prevent heat accumulation and overheating. happened. It can be understood that the heating element 122 is not limited to being a heating film, and it can also be other suitable heating elements such as a heating wire, a heating sheet, and the like.
在点阵式发热轨迹通过控制发热膜各处的电阻值来实现发热点的热量控制，由Q=I2·R·t知，在整个体系的电流一致的前提下，电阻大的位置产生热量多，所以可以使用多种方式控制不同位置的电阻。可以提供的一种方式包括控制发热点（发热单元1223a）的材料为高电阻率的发热材料如（镍铬合金），导电材料（导电单元1223b）为低电阻率的导体材料（如银），这样只会在发热点处产生热量而导电轨迹几乎不产生热量。另外，在使用同种材料的情况下可以通过调整发热膜线宽（如图12示）或者厚度控制局部电阻。可理解地，在一些实施例中，也可以使发热点（发热单元1223a）处的线宽变细，使导电单元1223b的线宽***也可以达到类似的效果。由此可知，可以通过调节材料电阻率调整局部的电阻和热流密度，也可以通过调节发热膜线宽调整局部的电阻和热流密度。In the dot-matrix heating track, the heat control of the heating point is realized by controlling the resistance value of the heating film at each place. According to Q=I2·R·t, under the premise that the current of the whole system is consistent, the position with high resistance generates more heat , so the resistance at different locations can be controlled in a number of ways. One method that can be provided includes controlling the heating point (heating unit 1223a) as a high-resistivity heating material such as (nickel-chromium alloy), and the conductive material (conducting unit 1223b) as a low-resistivity conductor material (such as silver), This will only generate heat at the hot spots and the conductive traces will generate almost no heat. In addition, in the case of using the same material, the local resistance can be controlled by adjusting the line width (as shown in Figure 12) or thickness of the heating film. Understandably, in some embodiments, the line width at the heating point (heating unit 1223 a ) can also be made thinner, and the line width of the conductive unit 1223 b can be thickened to achieve a similar effect. It can be seen that the local resistance and heat flux can be adjusted by adjusting the resistivity of the material, and the local resistance and heat flux can also be adjusted by adjusting the line width of the heating film.
综上可知，本发明一些实施例中的雾化芯12至少具有诸多有益效果：In summary, it can be seen that the atomizing core 12 in some embodiments of the present invention has at least many beneficial effects:
（1）通过形成分散的发热点，影响的范围更宽。(1) By forming scattered hot spots, the scope of influence is wider.
（2）发热点的热流密度高，升温速率快，有利于快速雾化和出烟。(2) The heat flux density at the heating point is high, and the heating rate is fast, which is conducive to rapid atomization and smoke emission.
（3）发热点向多个方向导热，热量不容易积聚，防止热量的积聚和过热状态的发生。(3) The heating point conducts heat in multiple directions, and the heat is not easy to accumulate, preventing the accumulation of heat and the occurrence of overheating.
（4）通过调节发热点间距使热影响区重合，形成较为均匀的温度分布。(4) The heat-affected zone overlaps by adjusting the distance between the heating points to form a relatively uniform temperature distribution.
再可以理解地，上述加热元件122的发热单元1223a在一些实施例中也不限于需要通过导电单元1223b连接起来，发热单元1223a可以是电磁场控制的发热单元，此时，其可以独立的发热点。It can be understood that, in some embodiments, the heating unit 1223a of the heating element 122 is not limited to be connected through the conductive unit 1223b. The heating unit 1223a can be a heating unit controlled by an electromagnetic field. At this time, it can be an independent heating point.
图15示出了本发明一些实施例中的雾化芯12c，该雾化芯12c可作为上述雾化芯12的一个替代。如图15所示，该雾化芯12c可包括多孔体121以及设置于多孔体121表面的加热元件122。多孔体121在一些实施例中可包括烧结式多孔陶瓷体，用于吸取液态气溶胶生成基质。该加热元件122在一些实施例中可为以镍铬合金为发热材料、银为导电材料的发热膜，该发热膜可采用印刷的方式形成于多孔体121的表面，其厚度可为100μm。该加热元件122在一些实施例中还包括用于与第一电极引线相连接的第一电极连接部1221、用于第二电极引线相连接的第二电极连接部1222以及连接于该第一电极连接部1221和第二电极连接部1222之间的发热部1223。Fig. 15 shows an atomizing core 12c in some embodiments of the present invention, which can be used as a substitute for the above atomizing core 12. As shown in FIG. 15 , the atomizing core 12c may include a porous body 121 and a heating element 122 disposed on the surface of the porous body 121 . Porous body 121 may comprise a sintered porous ceramic body in some embodiments for absorbing a liquid aerosol-generating substrate. In some embodiments, the heating element 122 can be a heating film with nickel-chromium alloy as the heating material and silver as the conductive material. The heating film can be formed on the surface of the porous body 121 by printing, and its thickness can be 100 μm. In some embodiments, the heating element 122 also includes a first electrode connection part 1221 for connecting to a first electrode lead, a second electrode connection part 1222 for connecting a second electrode lead, and a second electrode connection part 1222 connected to the first electrode lead. The heating part 1223 between the connecting part 1221 and the second electrode connecting part 1222 .
发热部1223在一些实施例中包括若干平行间隔布置的发热带，每一发热带包括交替布置的若干镍铬合金材料制成的发热单元1223a和若干银制成的导电单元1223c，这些发热单元1223a和导电单元1223c可呈线型，且线宽可为200μm左右，各发热单元1223a在横向和纵向的距离是等间距的，所以可以形成点阵式的发热轨迹分布。在常规的电子雾化装置中，每相邻两个发热点的间隔距离可设置在0.2-5mm之间，该距离下热量能够成呈现良好的均匀分布形态。可以理解地，该距离可以根据发热点的发热温度高低、雾化速率快慢等诸多因素进行调整，以实现热量的均匀分布为最佳。例如，当雾化速率一定时，如果发热点的发热温度越高，那么发热点之间的间隔距离可以相应地增大一些。In some embodiments, the heating part 1223 includes a plurality of heating bands arranged in parallel at intervals, and each heating band includes a number of heating units 1223a made of nickel-chromium alloy material and a number of conductive units 1223c made of silver arranged alternately, and these heating units 1223a The conductive unit 1223c can be in the shape of a line, and the line width can be about 200 μm, and the distances between the heating units 1223a in the horizontal and vertical directions are equal, so that a dot matrix heating track distribution can be formed. In a conventional electronic atomization device, the distance between every two adjacent heating points can be set between 0.2-5 mm, and the heat can be distributed in a good and uniform form under this distance. It can be understood that the distance can be adjusted according to many factors such as the heating temperature of the heating point, the speed of atomization, etc., so as to achieve the best uniform distribution of heat. For example, when the atomization rate is constant, if the heating temperature of the heating points is higher, the distance between the heating points can be increased accordingly.
