请参阅图1，本申请实施例提供了一种发热体100，发热体100为平板片状结构，包括发热部10以及沿发热部10横向两端延伸形成的导电部20，发热部10沿横向划分为位于中部的第一发热区域A以及沿位于第一发热区域A两侧的第二发热区域B，第一发热区域A中相邻两个发热段之间的间距大于第二发热区域B中相邻两个发热段之间的间距；通过如此结构，在发热体100通电发热时，可以使中部第一发热区域A的温度降低，使两侧第二发热区域B的温度升高，以减少发热部10的中部温度与两侧温度之间的温差，从而使得整个发热部10的温度更均匀。本实施例发热体100在应用于具有双进液通道的雾化器中时，两侧的第二发热区域B分别靠近或对应两个进液通道的下方，更利于对导油体内的雾化液进行加热雾化。Please refer to Fig. 1, the embodiment of the present application provides a heating element 100, the heating element 100 is a flat sheet structure, including the heating part 10 and the conductive part 20 extending along the lateral ends of the heating part 10, the heating part 10 extends along the lateral direction Divided into the first heating area A located in the middle and the second heating area B located on both sides of the first heating area A, the distance between two adjacent heating segments in the first heating area A is larger than that in the second heating area B The distance between two adjacent heating sections; through such a structure, when the heating element 100 is energized and heated, the temperature of the first heating area A in the middle can be reduced, and the temperature of the second heating area B on both sides can be increased to reduce The temperature difference between the middle temperature of the heating part 10 and the temperature on both sides makes the temperature of the whole heating part 10 more uniform. When the heating element 100 of this embodiment is applied to an atomizer with double liquid inlet channels, the second heating regions B on both sides are respectively close to or correspond to the bottom of the two liquid inlet channels, which is more conducive to the atomization in the oil guide body The liquid is heated and atomized.
在实际应用时，发热体100组装到雾化器的雾化组件中，贴合或嵌设于雾化组件中导油体的雾化面上，导电部20与雾化器的电极接触电连接，从而通过电极与供电电源和控制电路电连接，由控制电路控制供电电源为发热体100进行供电，以使发热体100的发热部10对导油体中吸收的雾化液进行加热雾化，以产生可供使用者吸食的气溶胶。In practical application, the heating element 100 is assembled into the atomization assembly of the atomizer, attached or embedded on the atomization surface of the oil guide in the atomization assembly, and the conductive part 20 is electrically connected to the electrode of the atomizer. , so that the electrodes are electrically connected to the power supply and the control circuit, and the control circuit controls the power supply to supply power to the heating element 100, so that the heating part 10 of the heating element 100 heats and atomizes the atomized liquid absorbed in the oil guide, To produce an aerosol that can be inhaled by the user.
本实施例发热体100是由金属片通过蚀刻方式形成的一个整体，例如采用镍片、镍铬片、铁铬铝片、不锈钢片、金属钛片或合金片等导电金属件，其材料可根据实际情况进行选择，发热体100的厚度为0.05-0.2mm，例如，为0.1mm。发热体100的发热部10可以是各种发热较为均匀的形状，例如网格状、条纹状、S形、折线形、波浪形、锯齿形、螺旋形、圆形或矩形。In this embodiment, the heating element 100 is formed as a whole by etching a metal sheet, such as a nickel sheet, a nickel-chromium sheet, an iron-chromium-aluminum sheet, a stainless steel sheet, a metal titanium sheet or an alloy sheet and other conductive metal parts, and its material can be determined according to Depending on the actual situation, the thickness of the heating element 100 is 0.05-0.2 mm, for example, 0.1 mm. The heating part 10 of the heating element 100 can be in various shapes with relatively uniform heat generation, such as grid shape, stripe shape, S shape, zigzag shape, wave shape, zigzag shape, spiral shape, circle or rectangle.
具体地，发热部10为呈S形或连续S形弯曲的发热丝，包括若干第一发热段11，若干第一发热段11沿横向间隔设置，并基本沿纵向延伸，且相邻两个第一发热段11的一端通过第二发热段12连接在一起，另一端相互隔开，发热部10的两个自由端分别连接于两个导电部20；第一发热区域A中相邻两个第一发热段11之间的间距为D1，第二发热区域B中相邻两个第一发热段11之间的间距为D2，D1大于D2。Specifically, the heating part 10 is a heating wire bent in an S shape or a continuous S shape, and includes a plurality of first heating sections 11 arranged at intervals in the transverse direction and extending substantially in the longitudinal direction, and adjacent to two second heating sections. One end of a heating section 11 is connected together through the second heating section 12, and the other end is spaced apart from each other. The two free ends of the heating section 10 are respectively connected to the two conductive sections 20; The distance between one heating section 11 is D1, the distance between two adjacent first heating sections 11 in the second heating area B is D2, and D1 is greater than D2.
如此，当发热体100通电发热时，发热部10的中间第一发热区域A两第一发热段11的间距较大，减少了第一发热区域A单位面积所产生的热量，降低了第一发热区域A的温度；而两侧第二发热区域B中两第一发热段11的间距较小，增加了第二发热区域B单位面积所产生的热量，增加了第二发热区域B所产生的热量，提高了第二发热区域B的温度，从而减少了发热部10的中部温度与两侧温度之间的温差，使发热部10沿横向分布的温度更加均匀，提高发热体100的雾化效果，避免了因局部温度过高而导致糊芯情况的发生。In this way, when the heating element 100 is energized and generates heat, the distance between the two first heating sections 11 in the middle first heating area A of the heating part 10 is relatively large, which reduces the heat generated per unit area of the first heating area A and reduces the first heat generation. The temperature of the area A; and the distance between the two first heating sections 11 in the second heating area B on both sides is relatively small, which increases the heat produced per unit area of the second heating area B and increases the heat generated by the second heating area B , the temperature of the second heating area B is increased, thereby reducing the temperature difference between the temperature in the middle of the heating part 10 and the temperature on both sides, making the temperature distribution of the heating part 10 along the lateral direction more uniform, and improving the atomization effect of the heating element 100, It avoids the occurrence of core burnt due to excessive local temperature.
在本实施例中，导电部20的横截面积由靠近发热部10的一端向另一端逐渐增大延伸，且导电部20的最小横截面积大于发热部10中发热段的横截面积。In this embodiment, the cross-sectional area of the conductive part 20 gradually increases from one end close to the heating part 10 to the other end, and the minimum cross-sectional area of the conductive part 20 is larger than the cross-sectional area of the heating section in the heating part 10 .
具体地，第一发热段11和第二发热段12的横截面积可以相同，即两者的宽度为d1，并小于导电部20的最小宽度d2，通过限定导电部20横截面积的渐变结构，在保证导电部20对发热部10有足够支撑强度的同时，使得发热体100在通电发热时，导电部20不发热，且由于导电部20与发热部10连接的一端为较小端，因此减少了发热部10的热量向导电部20方向的传导，使产生的热量集中于发热部10区域，使雾化效果更好，并提高了热量利用效率。Specifically, the cross-sectional area of the first heating section 11 and the second heating section 12 can be the same, that is, the width of both is d1, which is smaller than the minimum width d2 of the conductive part 20. While ensuring that the conductive part 20 has sufficient support strength for the heating part 10, the conductive part 20 does not generate heat when the heating element 100 is energized and generates heat. The conduction of the heat from the heating part 10 to the direction of the conductive part 20 is reduced, the generated heat is concentrated in the area of the heating part 10, the atomization effect is better, and the heat utilization efficiency is improved.
其中，为方便导电部20与电极的接触连接，导电部20远离发热部10的一端为圆弧状，从而形成与所接触电极大小适配的圆形接触区域21，如此保证了导电部20与电极接触面积以及发热体100的整体强度。导电部20于接触区域21之外的位置可开设有至少一个镂空孔，以进一步地减少发热部10向导电部20方向传导热量。Among them, in order to facilitate the contact connection between the conductive part 20 and the electrode, the end of the conductive part 20 away from the heating part 10 is in the shape of an arc, thereby forming a circular contact area 21 that is adapted to the size of the contacted electrode, thus ensuring that the conductive part 20 is in contact with the electrode. The electrode contact area and the overall strength of the heating element 100. The conductive portion 20 may be provided with at least one hollow hole at a position outside the contact area 21 to further reduce heat conduction from the heat generating portion 10 to the conductive portion 20 .
在本实施例中，导电部20远离发热部10的一端还延伸形成有一延伸部30，延伸部30的横截面积小于导电部20的最小横截面积。即延伸部30的宽度d3小于导电部20的最小宽度d2。In this embodiment, the end of the conductive part 20 away from the heating part 10 further extends to form an extension part 30 , the cross-sectional area of the extension part 30 is smaller than the minimum cross-sectional area of the conductive part 20 . That is, the width d3 of the extension portion 30 is smaller than the minimum width d2 of the conductive portion 20 .
在一些实施例中，各第一发热段11的横截面积可以由中部向纵向两端逐渐缩小延伸。也就是说，第一发热段11的中部宽度为H1，第一发热段11的两端宽度均为H2，H1大于H2，通过如此结构，在发热体100两端的导电部20加载电压不变的情况下，使第一发热段11的中心位置功率微调降低，而第一发热段11的两端位置功率微调升高，使发热部10沿纵向分布的温度更加均匀，配合各第一发热段11的间距设置，从而使整个发热部10的整体区域温度更加均匀。在本实施例中，第二发热段12的宽度与第一发热段11两端的宽度H2相同。In some embodiments, the cross-sectional area of each first heating segment 11 may gradually decrease from the middle to both longitudinal ends. That is to say, the width of the middle part of the first heating section 11 is H1, the width of both ends of the first heating section 11 is H2, and H1 is greater than H2. With such a structure, the conductive parts 20 at both ends of the heating element 100 are loaded with a constant voltage. Under normal circumstances, the fine-tuning of the central position of the first heating section 11 is reduced, and the power of the two ends of the first heating section 11 is fine-tuned to increase, so that the temperature of the heating part 10 along the longitudinal distribution is more uniform, and cooperates with each first heating section 11 The spacing is set, so that the temperature of the whole area of the whole heating part 10 is more uniform. In this embodiment, the width of the second heat generating section 12 is the same as the width H2 of both ends of the first heat generating section 11 .
结合图2所示，在实际制造时，选用一整块大尺寸的金属片，将金属片划分为蚀刻区101，由蚀刻区101围成并与发热体100相对应的成型区、围绕各成型区和蚀刻区101的边框区102，当将蚀刻区101去除后，成型区所形成的各发热体100分别通过其两端的延伸部30与边框区102连接在一起，如此可实现自动化从金属片上切割下来获得多个发热体100，实现批量化生产。As shown in FIG. 2 , in actual manufacturing, a whole piece of large-sized metal sheet is selected, and the metal sheet is divided into an etching area 101, and the forming area surrounded by the etching area 101 and corresponding to the heating element 100 surrounds each forming area. area and the frame area 102 of the etching area 101, when the etching area 101 is removed, each heating element 100 formed in the molding area is connected to the frame area 102 through the extensions 30 at both ends, so that automation can be realized from the metal sheet Cutting off to obtain a plurality of heating elements 100 to realize mass production.
具体地，边框区102对应各延伸部30位置形成有矩形或三角形的连接点103，延伸部30通过连接点103与边框区102连接一起，且延伸部30与连接点103之间的接触宽度为大于0.15mm或小于3mm，例如，为2mm，如此减少了延伸部30上的切割痕迹，并且切割痕迹位于延伸部30上，使切割痕迹避开了与电极接触的接触区域21，保证了导电部20与电极稳定接触。Specifically, the frame area 102 is formed with rectangular or triangular connection points 103 corresponding to the positions of the extensions 30, the extensions 30 are connected to the frame area 102 through the connection points 103, and the contact width between the extensions 30 and the connection points 103 is Greater than 0.15 mm or less than 3 mm, for example, 2 mm, the cutting marks on the extension part 30 are reduced in this way, and the cutting marks are located on the extension part 30, so that the cutting marks avoid the contact area 21 in contact with the electrode, ensuring that the conductive part 20 is in steady contact with the electrodes.
结合图3所示，为了给发热部10提供足够的支撑强度，本实施例中发热部10在位于纵向的两侧分别连接有至少一个固定部13。本申请发热体100在组装到雾化器中时，通过导油体与支撑体300上下方向夹持固定发热体100以形成发热组件，该发热组件安装在雾化底座200的顶端，支撑体300对应发热部10的位置开设有与雾化底座200顶端雾化腔201连通的通道，利用支撑体300来对导电部20和固定部13进行支撑，以使发热部10完全贴设于导油体上，保持发热部10平整，确保发热部10与导油体不分离。As shown in FIG. 3 , in order to provide sufficient supporting strength for the heating part 10 , in this embodiment, the heating part 10 is respectively connected with at least one fixing part 13 on both sides in the longitudinal direction. When the heating element 100 of this application is assembled into the atomizer, the heating element 100 is clamped and fixed by the oil guide body and the support body 300 in the up and down direction to form a heating element. Corresponding to the position of the heating part 10, there is a channel communicating with the atomization chamber 201 at the top of the atomization base 200, and the support body 300 is used to support the conductive part 20 and the fixing part 13, so that the heating part 10 is completely attached to the oil guide body Above, keep the heating part 10 flat and ensure that the heating part 10 is not separated from the oil guiding body.
两侧固定部13的末端可凸出支撑体300的边缘，通过将凸出部分向支撑体300方向弯折而夹持卡紧到支撑体300的两侧，以支撑和更好地固定发热体100，使发热部10不易变形和位移；当然，还可以根据实际情况需要在固定部13上开设一个或多个镂空孔，以减少发热部10所产生的热量向支撑体300上传递。The ends of the fixing parts 13 on both sides can protrude from the edge of the support body 300, and the protruding part is clamped and clamped to both sides of the support body 300 by bending the protruding part toward the direction of the support body 300, so as to support and better fix the heating element 100, so that the heating part 10 is not easily deformed and displaced; of course, one or more hollow holes can also be set on the fixing part 13 according to the actual situation, so as to reduce the heat generated by the heating part 10 from being transferred to the support body 300.
第二发热段12为中部沿纵向向外凸出的弧形状，以提高发热部10发热时的沿纵向方向的热量均匀分布；每一第二发热段12连接有一个固定部13，固定部13沿纵向延伸，以提高对发热部10的支撑强度。在其他实施例中，固定部13的数量也可根据情况需要进行选择，例如，在保证对发热部10支撑强度的同时，间隔一个第二发热段12设置一个固定部13。The second heating section 12 is an arc shape in which the middle part protrudes longitudinally outwards, so as to improve the uniform distribution of heat in the longitudinal direction when the heating section 10 generates heat; each second heating section 12 is connected with a fixing part 13, and the fixing part 13 Extending in the longitudinal direction to improve the supporting strength of the heat generating part 10 . In other embodiments, the number of fixing parts 13 can also be selected according to the needs of the situation, for example, while ensuring the support strength of the heating part 10 , one fixing part 13 is provided at intervals of one second heating segment 12 .
图4为图1所示发热体100的替换实施例，本实施例发热体100与图1所示发热体100的主要区别在于：为了给发热部10提供足够的支撑强度，本实施例其中一部分固定部13沿靠近发热体100的一端倾斜延伸，另一部分固定部13沿靠近发热体100的另一端倾斜延伸。FIG. 4 is an alternative embodiment of the heating element 100 shown in FIG. 1. The main difference between the heating element 100 of this embodiment and the heating element 100 shown in FIG. The fixing part 13 extends obliquely along one end close to the heating element 100 , and another part of the fixing part 13 extends obliquely along the other end close to the heating element 100 .
结合图5所示，本实施例针对的是没有设置支撑体300结构的雾化器，即发热体100是直接安装在雾化底座200的顶端，由于雾化腔201的两侧需要贯穿以与雾化器的出气管连通，因此雾化底座200的顶面由雾化腔201分隔成左右两支撑面。具体的说，位于发热体100左半部分的固定部13向左边倾斜延伸，从而由雾化底座200的左支撑面支撑，位于发热体100右半边部分的固定部13向右倾斜延伸，从而由雾化底座200的右支撑面支撑，如此利用雾化底座200的顶面来对导电部20和固定部13进行支撑，以使发热部10完全贴设于导油体上，保持发热部10平整，以确保发热部10与导油体不分离。As shown in Fig. 5, this embodiment is aimed at the atomizer without the structure of the support body 300, that is, the heating element 100 is directly installed on the top of the atomization base 200, since the two sides of the atomization chamber 201 need to penetrate to communicate with The air outlet pipe of the atomizer is connected, so the top surface of the atomization base 200 is divided into left and right support surfaces by the atomization chamber 201 . Specifically, the fixing part 13 located on the left half of the heating element 100 extends obliquely to the left, so as to be supported by the left support surface of the atomization base 200, and the fixing part 13 located on the right half of the heating element 100 extends obliquely to the right, thereby being supported by the atomization base 200. The right support surface of the atomizing base 200 is supported, so that the conductive part 20 and the fixed part 13 are supported by the top surface of the atomizing base 200, so that the heating part 10 is completely attached to the oil guide body, and the heating part 10 is kept flat , to ensure that the heat generating part 10 is not separated from the oil guiding body.
请参阅图6所示，为本申请发热体100另一实施例的结构示意图，本实施例发热体100中的发热部10包括若干矩形状的发热丝14，若干发热丝14沿横向间隔设置，并依次串联于两个导电部20之间；每一发热丝14包括两个沿纵向延伸并平行相对的第一发热段11，两个第一发热段11的两端分别通过第二发热段12对应连接；在本实施例中，第二发热段12为直线段，每个第二发热段12上连接有沿纵向延伸的固定部13。Please refer to FIG. 6 , which is a schematic structural view of another embodiment of the heating element 100 of the present application. The heating part 10 in the heating element 100 of this embodiment includes several rectangular heating wires 14, and several heating wires 14 are arranged at intervals along the lateral direction. And sequentially connected in series between the two conductive parts 20; each heating wire 14 includes two first heating segments 11 extending longitudinally and parallel to each other, and the two ends of the first heating segments 11 respectively pass through the second heating segment 12 Corresponding connection; In this embodiment, the second heating section 12 is a straight section, and each second heating section 12 is connected with a fixing portion 13 extending longitudinally.
具体地，第一发热区域A中发热丝14的两个第一发热段11之间的间距为D3，第二发热区域B中发热丝14的两个第一发热段11之间的间距为D4，D3大于D4；从而当发热体100通电发热时，由于第一发热区域A中发热丝14的两个第一发热段11间距较大，减少了第一发热区域A单位面积所产生的热量，降低了第一发热区域A的温度；而两侧第二发热区域B中发热丝14的两个第一发热段11的间距较小，增加了第二发热区域B单位面积所产生的热量，提高了第二发热区域B的温度，从而减少了发热部10的中部温度与两侧温度之间的温差，使发热部10沿横向分布的温度更加均匀。Specifically, the distance between the two first heating segments 11 of the heating wire 14 in the first heating area A is D3, and the distance between the two first heating segments 11 of the heating wire 14 in the second heating area B is D4 , D3 is greater than D4; thus when the heating element 100 is energized to generate heat, since the distance between the two first heating segments 11 of the heating wire 14 in the first heating area A is relatively large, the heat generated per unit area of the first heating area A is reduced. The temperature of the first heating area A has been reduced; and the distance between the two first heating sections 11 of the heating wire 14 in the second heating area B on both sides is relatively small, which increases the heat produced per unit area of the second heating area B and improves The temperature of the second heat generating region B is reduced, thereby reducing the temperature difference between the temperature in the middle of the heat generating part 10 and the temperature on both sides, and making the temperature distribution of the heat generating part 10 along the lateral direction more uniform.
其中，相邻两个发热丝14之间通过串联部15连接，且串联部15的两端分别连接于与相邻两个发热丝14中对应一侧第一发热段11的中部，即串联部15所在直线将若干发热丝14分隔成上下对称的两个部分，每一发热丝14的上下两个部分是并联结构，若干发热丝14是串联结构。另外，第一发热段11和第二发热段12之间圆滑过渡，有利于热量均匀分布，避免了尖角部位热量堆叠集中而引起炸油发生。Wherein, two adjacent heating wires 14 are connected by a series part 15, and the two ends of the series part 15 are respectively connected to the middle part of the first heating section 11 on the corresponding side of the two adjacent heating wires 14, that is, the series part The straight line where 15 is located separates several heating wires 14 into two symmetrical parts up and down, the upper and lower parts of each heating wire 14 are in parallel structure, and several heating wires 14 are in series structure. In addition, the smooth transition between the first heating section 11 and the second heating section 12 is conducive to the uniform distribution of heat, and avoids the accumulation and concentration of heat at sharp corners to cause frying oil.
第一发热区域A中相邻两个发热丝14之间的间距大于第二发热区域B中相邻两个发热丝14之间的间距，即第一发热区域A中串联部15的长度为D5，第二发热区域B中串联部15的长度为D6，且D5大于D6，从而当发热体100通电发热时，进一步微调降低第一发热区域A的温度，微调提高第二发热区域B的温度，以使发热部10的中部温度趋于两侧温度，使发热部10沿横向分布的温度更加均匀。The spacing between two adjacent heating wires 14 in the first heating area A is larger than the spacing between two adjacent heating wires 14 in the second heating area B, that is, the length of the series part 15 in the first heating area A is D5 , the length of the series part 15 in the second heating area B is D6, and D5 is greater than D6, so that when the heating element 100 is energized and generates heat, the temperature of the first heating area A is further fine-tuned, and the temperature of the second heating area B is fine-tuned to increase, The temperature in the middle of the heat generating part 10 tends to the temperature at both sides, so that the temperature distribution of the heat generating part 10 along the lateral direction is more uniform.
在本实施例中，第一发热段11和第二发热段12的横截面积相同，即第一发热段11和第二发热段12的宽度d1小于导电部20的最小宽度d2，以使发热体100通电发热时导电部20不发热，使发热体100发热时所产生的热量集中在发热部10区域。In this embodiment, the cross-sectional areas of the first heating section 11 and the second heating section 12 are the same, that is, the width d1 of the first heating section 11 and the second heating section 12 is smaller than the minimum width d2 of the conductive part 20, so as to generate heat The conductive part 20 does not generate heat when the body 100 is energized and heats up, so that the heat generated by the heating body 100 is concentrated in the area of the heating part 10 .
需要说明的是，本实施例中各第一发热段11的横截面积也可采用渐变结构，即第一发热段11的宽度由中部向两端渐缩延伸，以使发热部10沿纵向分布的温度更加均匀。It should be noted that in this embodiment, the cross-sectional area of each first heating section 11 can also adopt a gradual change structure, that is, the width of the first heating section 11 tapers and extends from the middle to both ends, so that the heating section 10 is distributed along the longitudinal direction. temperature is more uniform.
第一发热区域A中串联部15的宽度可以设置成大于第二发热区域B中串联部15的宽度，从而进一步的降低了发热部10中心位置的温度，有利于发热部10的整体区域温度均匀。The width of the series part 15 in the first heat generating area A can be set to be larger than the width of the series part 15 in the second heat generating area B, thereby further reducing the temperature at the center of the heat generating part 10, which is conducive to the uniform temperature of the entire area of the heat generating part 10 .
请参阅图7所示，为本申请发热体100又一实施例的结构示意图，本实施例发热体100中发热部10包括若干菱形状的发热丝14，若干发热丝14沿横向依次串联于两个导电部20之间，每个发热丝14具有一菱形孔，第一发热区域A中发热丝14的菱形孔沿横向最大间距为D7，第二发热区域B中发热丝14的菱形孔沿横向最大间距为D8，D7大于D8。Please refer to FIG. 7 , which is a structural schematic diagram of another embodiment of the heating element 100 of the present application. The heating part 10 of the heating element 100 of this embodiment includes several rhombus-shaped heating wires 14, and the plurality of heating wires 14 are connected in series in two directions along the horizontal direction. Between two conductive parts 20, each heating wire 14 has a diamond-shaped hole, the diamond-shaped holes of the heating wire 14 in the first heating area A have a maximum distance of D7 along the transverse direction, and the diamond-shaped holes of the heating wire 14 in the second heating area B are along the lateral direction. The maximum spacing is D8, and D7 is greater than D8.
当发热体100通电发热时，减少了第一发热区域A单位面积所产生的热量，降低了第一发热区域A的温度；而增加了第二发热区域B单位面积所产生的热量，提高了第二发热区域B的温度，从而减少了发热部10的中部温度与两侧温度之间的温差，使发热部10沿横向分布的温度更加均匀。When the heating element 100 is energized to generate heat, the heat generated by the unit area of the first heating area A is reduced, and the temperature of the first heating area A is reduced; the heat generated by the unit area of the second heating area B is increased, and the second heating area B is increased. The temperature of the heating area B reduces the temperature difference between the middle temperature of the heating part 10 and the temperature on both sides, and makes the temperature distribution of the heating part 10 along the lateral direction more uniform.
具体地，本实施例中发热丝14包括两个相互平行的第一发热段11和两个相互平行的第二发热段12，两个第一发热段11和两个第二发热段12共同组成菱形状的发热丝14。第一发热段11和第二发热段12的横截面积相同，即第一发热段11和第二发热段12的宽度为d1，并小于导电部20的最小宽度d2，以使发热体100通电发热时导电部20不发热，使发热体100发热时所产生的热量集中在发热部10区域。Specifically, the heating wire 14 in this embodiment includes two first heating sections 11 parallel to each other and two second heating sections 12 parallel to each other, the two first heating sections 11 and the two second heating sections 12 together form Diamond-shaped heating wire 14. The cross-sectional area of the first heating section 11 and the second heating section 12 is the same, that is, the width of the first heating section 11 and the second heating section 12 is d1, which is smaller than the minimum width d2 of the conductive part 20, so that the heating element 100 is energized The conductive part 20 does not generate heat when heating, so that the heat generated by the heating element 100 is concentrated in the area of the heating part 10 .
若干发热丝14的短轴方向沿横向设置，长轴方向沿纵向设置，且本实施例中若干发热丝14直接串联连接，任意相邻两个发热丝14之间的连接点均发热体100沿纵向的中心线上，以使发热丝14发热时的沿纵向方向的上下两部分热量相同，有利于热量均匀分布。当然，在其他实施例中，若干发热丝14也可以间隔设置并依次串联连接。The short axis direction of several heating wires 14 is arranged along the horizontal direction, and the long axis direction is arranged along the longitudinal direction, and in this embodiment, several heating wires 14 are directly connected in series, and the connection points between any two adjacent heating wires 14 are arranged along the direction of the heating element 100. The longitudinal centerline is such that when the heating wire 14 generates heat, the heat of the upper and lower parts along the longitudinal direction is the same, which is conducive to the uniform distribution of heat. Of course, in other embodiments, several heating wires 14 may also be arranged at intervals and connected in series sequentially.
在本实施例中，每一发热丝14的长轴方向两端分别连接有一个固定部13，固定部13沿纵向延伸，也就是说，每一个固定部13与所连接的第一发热段11和第二发热段12形成一个Y型结构，从而提高了对发热部10的支撑强度。In this embodiment, each heating wire 14 is connected with a fixing part 13 at both ends of the long axis direction, and the fixing part 13 extends in the longitudinal direction, that is to say, each fixing part 13 is connected to the first heating section 11 It forms a Y-shaped structure with the second heating section 12, thereby improving the supporting strength of the heating section 10.
本实施例中的第一发热段11和第二发热段12的横截面积也可采用渐变结构设置，即第一发热段11和第二发热段12的宽度由远离固定部13的一端向靠近固定部13方向依次渐缩延伸，从而降低发热部10在横向中心线位置的温度，以使发热部10沿纵向分布的温度更加均匀。The cross-sectional area of the first heating section 11 and the second heating section 12 in this embodiment can also be set in a gradual structure, that is, the width of the first heating section 11 and the second heating section 12 is from one end away from the fixed part 13 to closer The direction of the fixing part 13 tapers and extends sequentially, so as to reduce the temperature of the heating part 10 at the transverse centerline position, so that the temperature distribution of the heating part 10 along the longitudinal direction is more uniform.
