本发明的实施方式Embodiments of the present invention
下面将通过具体实施例对本发明进行详细说明。The present invention will be described in detail below through specific examples.
实施例1：Example 1:
如图1所示，本发明具有定向微孔的雾化芯，由导液体1和发热体2构成，导液体1为具有微孔结构并可用于吸收、传导、储存雾化液的固体，导液体1设有吸液面11和雾化面12，吸液面11可与雾化器中储液腔连通将雾化液吸收传导至导液体1的内部，雾化面11可将储存于导液体1内的雾化液加热蒸发产生气雾，发热体2设于该雾化面11上。导液体1上设有许多自吸液面11直通雾化面12的定向微孔10。定向微孔是指一端指向另一端的、孔道方向确定的管状微孔，本发明的导液体上的许多定向微孔，其方向是相同的，包括垂直状、或斜线状的方向。As shown in Figure 1, the atomizing core with directional micropores in the present invention is composed of a conductive liquid 1 and a heating element 2. The conductive liquid 1 is a solid with a microporous structure and can be used to absorb, conduct, and store atomized liquid. The liquid 1 is provided with a liquid-absorbing surface 11 and an atomizing surface 12. The liquid-absorbing surface 11 can communicate with the liquid storage chamber in the nebulizer to absorb and conduct the atomized liquid to the inside of the guide liquid 1. The atomizing surface 11 can store it in the guide liquid. The atomized liquid in the liquid 1 is heated and evaporated to generate an aerosol, and the heating element 2 is arranged on the atomized surface 11 . The conductive liquid 1 is provided with many directional micropores 10 from the liquid-absorbing surface 11 to the atomizing surface 12 . Oriented micropores refer to tubular micropores with one end pointing to the other and with a defined channel direction. Many oriented micropores on the guide liquid of the present invention have the same direction, including vertical or oblique directions.
本发明具有定向微孔的雾化芯，因其导液体1上设有许多自吸液面直通雾化面的定向微孔10，该定向微孔的方向确定，雾化液的流向确定，雾化时可以得到及时补充，且雾化液的成分在微孔内不会造成堵塞，可以增加雾化量、提升气雾还原程度、高温时不容易产生焦味，口味很好。另外定向微孔形成毛细管的吸附作用，在雾化芯不工作时，具有一定吸附力或平衡力而不至于造成雾化液的泄漏。The atomizing core with directional micropores of the present invention is provided with many directional micropores 10 whose self-absorbing surface directly leads to the atomizing surface on the guide liquid 1. The direction of the directional micropores is determined, and the flow direction of the atomized liquid is determined. It can be replenished in time when atomized, and the components of the atomized liquid will not cause blockage in the micropores, which can increase the amount of atomization, improve the degree of aerosol reduction, and it is not easy to produce burnt smell at high temperature, and the taste is good. In addition, the directional micropores form the adsorption effect of the capillary. When the atomizing core is not working, it has a certain adsorption force or balance force so as not to cause leakage of the atomized liquid.
发热体2包括设于导液体的雾化面12上的纳米级的金属镀膜层2，金属镀膜层2在定向微孔10的位置设有贯通的膜孔（图中未示）。金属镀膜层2可以采用磁控溅射仪，通过物理气相沉积镀膜技术即PVD技术对导液体2的暴露表面进行纳米级金属镀膜。由于镀层属于纳米级，镀膜不会封堵原有的定向微孔，故金属镀膜层在定向微孔的位置形成了贯通的膜孔。金属镀膜层2可以通电发热，定向微孔10渗出的雾化液可进一步通过膜孔渗出，在金属镀膜层2的加热下，生成的气雾可以在金属镀膜层2的表面蒸发，加热蒸发面积大，同时不会堵住定向微孔，在金属镀膜层内侧、定向微孔中产生的气雾也可以通过膜孔10散发出来。这样也可以提高雾化量、增加气雾的还原程度。The heating element 2 includes a nano-scale metal coating layer 2 disposed on the atomizing surface 12 of the conductive liquid, and the metal coating layer 2 is provided with a through film hole (not shown in the figure) at the position of the oriented microhole 10 . The metal coating layer 2 can use a magnetron sputtering apparatus to perform nanoscale metal coating on the exposed surface of the conductive liquid 2 through physical vapor deposition coating technology, ie PVD technology. Since the coating is nanoscale, the coating will not block the original directional micropores, so the metal coating layer forms through film holes at the positions of the directional micropores. The metal coating layer 2 can be energized to generate heat, and the atomized liquid leaking out of the directional micropores 10 can further seep out through the film holes. Under the heating of the metal coating layer 2, the generated gas mist can be evaporated on the surface of the metal coating layer 2, heating The evaporation area is large, and the directional micropores will not be blocked at the same time, and the gas mist generated in the inner side of the metal coating layer and the directional micropores can also be emitted through the film holes 10. This can also increase the amount of atomization and increase the degree of reduction of the aerosol.
如图2所示，在本实施例中，金属镀膜层2包括相互贴合连接的过渡层21和发热层22，过渡层21与导液体的雾化面12贴合连接。过渡层21由金属钛构成，其厚度为5nm-200nm，发热层22由金属铂构成，其厚度为50nm-1500nm。As shown in FIG. 2 , in this embodiment, the metal coating layer 2 includes a transition layer 21 and a heat generating layer 22 that are bonded and connected to each other, and the transition layer 21 is bonded and connected to the atomizing surface 12 of the conductive liquid. The transition layer 21 is made of metal titanium with a thickness of 5nm-200nm, and the heat generating layer 22 is made of metal platinum with a thickness of 50nm-1500nm.
导液体1的构成材料包括单晶硅、玻璃、氧化硅、氧化铝、氮化硼、氧化钛中的至少一种。导液体1的厚度为0.5mm-10mm，导液体1的定向微孔直径为0.1um-200um。导液体1由单晶硅、玻璃、氧化硅、氧化铝、氮化硼、氧化钛等构成，其纯度高、杂质少，不会析出重金属等不健康的成分。另金属镀膜层由金属钛或金属铂构成，金属稳定性好，不易发生化学反应，也不会析出和产生重金属等不好的成分。The constituent material of the conductive liquid 1 includes at least one of single crystal silicon, glass, silicon oxide, aluminum oxide, boron nitride, and titanium oxide. The thickness of the conductive liquid 1 is 0.5mm-10mm, and the diameter of the directional micropores of the conductive liquid 1 is 0.1um-200um. The conductive liquid 1 is composed of single crystal silicon, glass, silicon oxide, aluminum oxide, boron nitride, titanium oxide, etc., which has high purity and less impurities, and will not precipitate unhealthy components such as heavy metals. In addition, the metal coating layer is made of metal titanium or metal platinum, which has good metal stability, is not prone to chemical reactions, and will not precipitate and produce undesirable components such as heavy metals.
如图3所示，发热体2还包括发热体两端连接设有的电极片23，该电极片可以通过印刷电路并烧结的方式制成金属电极层，如银电极层。As shown in FIG. 3 , the heating element 2 also includes an electrode sheet 23 connected to both ends of the heating element. The electrode sheet can be made into a metal electrode layer, such as a silver electrode layer, by printing a circuit and sintering.
如图4所示，其它实施例中，本发明具有定向微孔的雾化芯，还包括由储液介质构成的储液体3，储液体3与导液体的吸液面11抵触连接。储液体3具有储存、缓冲雾化液的作用，避免储液腔内的雾化液直接流向导液体1，减少液体压力、进一步减少雾化液自导液体1泄漏的机会。As shown in FIG. 4 , in other embodiments, the atomizing core with directional micropores of the present invention also includes a liquid storage 3 composed of a liquid storage medium, and the liquid storage 3 is in conflicting connection with the liquid-conducting liquid-absorbing surface 11 . The storage liquid 3 has the function of storing and buffering the atomized liquid, preventing the atomized liquid in the liquid storage chamber from flowing directly into the guide liquid 1, reducing the pressure of the liquid, and further reducing the chance of the atomized liquid leaking from the guide liquid 1.
其它实施例中，发热体也可以是金属发热丝、或金属发热片（图中未示）。In other embodiments, the heating element may also be a metal heating wire or a metal heating sheet (not shown in the figure).
