为了更清楚的阐释本申请的整体构思，下面结合说明书附图以示例的方式进行详细说明。In order to explain the overall concept of the application more clearly, a detailed description will be given below by way of example in conjunction with the accompanying drawings of the specification.
在本申请中，应理解，诸如“包括”或“具有”等术语旨在指示本说明书中所公开的特征、数字、步骤、行为、部件、部分或其组合的存在，并且不旨在排除一个或多个其他特征、数字、步骤、行为、部件、部分或其组合存在的可能性。In this application, it should be understood that terms such as "including" or "having" are intended to indicate the existence of the features, numbers, steps, actions, components, parts, or combinations thereof disclosed in this specification, and are not intended to exclude one Or the possibility of the existence of multiple other features, numbers, steps, behaviors, components, parts or combinations thereof.
另外还需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。In addition, it should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present application will be described in detail with reference to the drawings and in conjunction with the embodiments.
参考图1和图2，本申请的实施例提供一种加热器，包括：第一底座1和固定在第一底座1的上表面上的发热结构2，发热结构2和第一底座1围成中空结构；发热结构2包括导热层21、位于导热层21内侧的绝缘层22、以及在绝缘层22内表面上的导电发热体23；导电发热体23与穿透第一底座1的电极结构1a电连接。1 and 2, the embodiment of the present application provides a heater, including: a first base 1 and a heating structure 2 fixed on the upper surface of the first base 1, the heating structure 2 and the first base 1 enclose Hollow structure; the heating structure 2 includes a thermally conductive layer 21, an insulating layer 22 located inside the thermally conductive layer 21, and a conductive heating element 23 on the inner surface of the insulating layer 22; a conductive heating element 23 and an electrode structure 1a penetrating the first base 1 Electric connection.
绝缘层22包裹导电发热体23，实现导电发热体23与外界的绝缘以及对导电发热体23的第一重保护。同时，绝缘层22应当具有良好的热导率，从而将导电发热体23产生的热量快速地散发出去。为此，绝缘层22的可选材料包括：玻璃、陶瓷、填充型导热高分子材料或石英中的至少一项。The insulating layer 22 wraps the conductive heating element 23 to realize the insulation of the conductive heating element 23 from the outside and the first protection of the conductive heating element 23. At the same time, the insulating layer 22 should have good thermal conductivity, so as to quickly dissipate the heat generated by the conductive heating element 23. To this end, the optional material of the insulating layer 22 includes at least one of glass, ceramic, filled thermally conductive polymer material, or quartz.
导热层21位于绝缘层22的外侧，应当具有比绝缘层22更好的热导率，从而更快地将热量散发出去。同时导热层21的结构应当较为坚固，从而起到对导热层21内的绝缘层22以及导电发热体23提供进一步的机械保护。为此，导热层21的材料可选择金属或合金。The thermal conductive layer 21 is located outside the insulating layer 22, and should have a better thermal conductivity than the insulating layer 22, so as to dissipate heat faster. At the same time, the structure of the thermal conductive layer 21 should be relatively strong, so as to provide further mechanical protection for the insulating layer 22 and the conductive heating element 23 in the thermal conductive layer 21. For this reason, the material of the heat-conducting layer 21 can be metal or alloy.
导电发热体23应当较为容易地制作在绝缘层22的内表面上。为此，导电发热体23的可选材料包括：金属、合金、碳化物、氮化物、二硅化钼和发热金属浆料中的至少一项。The conductive heating element 23 should be easily fabricated on the inner surface of the insulating layer 22. To this end, the optional material of the conductive heating element 23 includes at least one of metal, alloy, carbide, nitride, molybdenum disilicide, and heating metal paste.
如将该加热器应用在加热不燃烧烟具中，参考图8，驱动电路4通过电极结构1a为导电发热体23提供驱动功率。For example, if the heater is applied to a heating and non-combustion smoking device, referring to FIG. 8, the driving circuit 4 provides driving power to the conductive heating element 23 through the electrode structure 1a.
由于绝缘层22和导热层21对导电发热体23提供双重机械保护，该发热器的机械稳定性较佳。Since the insulating layer 22 and the thermal conductive layer 21 provide double mechanical protection to the conductive heating element 23, the mechanical stability of the heating element is better.
底座部分(包括第一底座1以及后述的第二底座7)材料需要有良好地隔热性能，此部分需要将加热器内部的热量阻隔住，防止热量从下方散出。底座部分可以和加热器具内部结构相配合，从而达到固定加热器的目的。当然，底座部分与导热层21接触的部分应当密封，防止烟料进入加热器内部。The material of the base part (including the first base 1 and the second base 7 described later) needs to have good heat insulation performance, and this part needs to block the heat inside the heater to prevent the heat from escaping from below. The base part can be matched with the internal structure of the heating device, so as to achieve the purpose of fixing the heater. Of course, the part of the base part in contact with the heat conducting layer 21 should be sealed to prevent smoke from entering the heater.
相应的，按照图1当前视角，底座的下表面上镶有正负极(即图1和图2中的两个电极结构1a)，正负极的内部一端与加热器内部导电加热体23两端连接在一起，正负极的外部端与驱动电路4连接在一起。正负极可以采用插座的形式，也可以采用顶针连接器的形式，或者直接采用两根导线的形式。Correspondingly, according to the current view of FIG. 1, the bottom surface of the base is inlaid with positive and negative electrodes (that is, the two electrode structures 1a in Figures 1 and 2). The terminals are connected together, and the external terminals of the positive and negative electrodes are connected to the driving circuit 4 together. The positive and negative poles can be in the form of a socket, a thimble connector, or directly in the form of two wires.
参考图3，导电发热体23呈螺纹状。参考图4，导电发热体23展开至一个平面后呈开口方向交替朝向第一底座1和远离第一底座1的弯折线。当然，导电发热体23也可以呈开口朝向第一底座1的U型。本领域技术人员可根据实际需要灵活设定导电发热体23的形状。Referring to FIG. 3, the conductive heating element 23 has a threaded shape. Referring to FIG. 4, after the conductive heating element 23 is expanded to a plane, the opening direction alternately faces the bending line of the first base 1 and away from the first base 1. Of course, the conductive heating element 23 may also be U-shaped with an opening facing the first base 1. Those skilled in the art can flexibly set the shape of the conductive heating element 23 according to actual needs.
参考图8，注意到为将导电发热体23贴附在绝缘层22内表面上，绝缘层22的内表面包围出一定的空间。在贴附导电发热体23后，仍会留有一定空间。该空间可以用于放置测温元件3。测温元件3靠近导电发热体23，可以对导电发热体23的温度进行精确地测量。掌握了导电发热体23的温度，也就能够较为精确地控制导电发热体23的温度。即使导电发热体23的电阻温度系数偏差较大，也能够较为精确地调整驱动电路4的输出功率，从而将导电发热体23的温度控制在预期的温度。避免了导电发热体23的发热性质的偏差造成最终加热不燃烧烟具加热性能的偏差，也就保证了最终烟草产生的烟雾的口感的一致性。Referring to FIG. 8, it is noted that in order to attach the conductive heating element 23 to the inner surface of the insulating layer 22, the inner surface of the insulating layer 22 encloses a certain space. After attaching the conductive heating element 23, there will still be a certain space. This space can be used to place the temperature measuring element 3. The temperature measuring element 3 is close to the conductive heating body 23, and the temperature of the conductive heating body 23 can be accurately measured. Knowing the temperature of the conductive heating element 23 can control the temperature of the conductive heating element 23 more accurately. Even if the temperature coefficient of resistance of the conductive heating element 23 has a large deviation, the output power of the driving circuit 4 can be adjusted more accurately, so that the temperature of the conductive heating element 23 can be controlled at a desired temperature. It avoids the deviation of the heating properties of the conductive heating element 23 from causing the deviation of the heating performance of the final heating and non-combustion smoking device, which also ensures the consistency of the taste of the smoke produced by the final tobacco.
以下为在中空区域100放置测温元件3的一种实现方式。The following is an implementation manner of placing the temperature measuring element 3 in the hollow area 100.
参考图5和图6，第一底座1上开设有测温插孔1b，测温插孔1b与中空区域100相对。测温插孔1b为一个通孔。Referring to FIGS. 5 and 6, the first base 1 is provided with a temperature measuring socket 1 b, and the temperature measuring socket 1 b is opposite to the hollow area 100. The temperature measuring socket 1b is a through hole.
与此相配合，参考图7和图8，加热器还包括第二底座7和固定在第二底座7上的测温元件3，测温元件3位于中空区域100内，第二底座7固定在测温插孔1b内，测温元件3与穿透第二底座7的电极结构1a电连接。In conjunction with this, referring to Figures 7 and 8, the heater also includes a second base 7 and a temperature measuring element 3 fixed on the second base 7. The temperature measuring element 3 is located in the hollow area 100, and the second base 7 is fixed on In the temperature measuring socket 1b, the temperature measuring element 3 is electrically connected to the electrode structure 1a penetrating the second base 7.
使用过程中，将图7所示的结构从测温插孔1b***到第一底座1和发热结构2围成的中空区域100内，然后将第二底座7与第一底座1固定在一起(例如粘贴或者挤压的方式)。从而得到封闭的中空区域100。防止热量对第一底座1周围的驱动电路4造成损伤。During use, insert the structure shown in Figure 7 from the temperature measuring socket 1b into the hollow area 100 enclosed by the first base 1 and the heating structure 2, and then fix the second base 7 and the first base 1 together ( For example, pasting or squeezing). Thus, a closed hollow area 100 is obtained. Prevent the heat from damaging the driving circuit 4 around the first base 1.
以下为在中空区域100放置测温元件3的另一种实现方式。The following is another implementation manner of placing the temperature measuring element 3 in the hollow area 100.
参考图8，加热器还包括测温元件3，测温元件3位于中空区域100内，测温元件3与穿透第一底座1的电极结构1a电连接。Referring to FIG. 8, the heater further includes a temperature measuring element 3, the temperature measuring element 3 is located in the hollow area 100, and the temperature measuring element 3 is electrically connected to the electrode structure 1 a penetrating the first base 1.
与前述实现方式不同之处在于，第一底座1无测温插孔1b。连接测温元件3的电极结构1a和连接导电发热体23的测温元件3都是通过穿透第一基底的电极结构1a与外界的驱动电路4相连的。当然，驱动电路4应当能够读取测温元件3产生的电信号。The difference from the foregoing implementation is that the first base 1 does not have a temperature measuring socket 1b. The electrode structure 1a connected to the temperature measuring element 3 and the temperature measuring element 3 connected to the conductive heating element 23 are both connected to the external driving circuit 4 through the electrode structure 1a that penetrates the first substrate. Of course, the driving circuit 4 should be able to read the electrical signal generated by the temperature measuring element 3.
可选地，测温元件3包括热电偶或热电阻或热敏电阻。Optionally, the temperature measuring element 3 includes a thermocouple or a thermal resistance or a thermistor.
如将该加热器应用在加热不燃烧烟具中，发热结构2的形状应当适于***烟草内。基于此，发热结构2的外表面呈按照远离上表面的方向延伸的针状、片状、柱状和顶部倒角处理的柱状。如发热体外边面呈柱状，其横截面可以是圆形、多边形等多种形状。If the heater is used in a heating and non-combustion smoking appliance, the shape of the heating structure 2 should be suitable for being inserted into the tobacco. Based on this, the outer surface of the heating structure 2 has a needle shape, a sheet shape, a column shape, and a top chamfered column shape extending in a direction away from the upper surface. For example, the outer edge of the heating element is cylindrical, and its cross-section can be round, polygonal and other shapes.
