[0033] The utility model provides a heating element.
[0034] See also Figures 1 to 5 In one embodiment of the utility model, the heating element includes a heating plate 100 and a heating wire, which is embedded in the heating plate 100 and can generate heat after being energized, and radiate the heat to the outside through the heating plate 100. The material of the heating plate 100 is ceramic. After being fired and formed, the ceramic has a honeycomb-shaped arrangement of fine pores inside, so that the ceramic has good heat storage performance. When the heating wire stops being energized, the heating element with a ceramic structure can use the stored heat to radiate heat to the outside, which is beneficial to reducing the electric energy required by the heating wire when the heating element continues to heat the outside. The heating plate 100 has a first side surface 11 and a second side surface 12 that are relatively arranged in the thickness direction. At least one of the first side surface 11 and the second side surface 12 is integrally formed with a heat dissipation protrusion 200. The heat dissipation protrusion 200 enables the heating plate 100 to have a larger radiation range, so as to expand the heating range of the heating plate 100, which is beneficial to quickly heat up the space around the heating element.
[0035] See also Figures 1 to 3In one embodiment, the heat dissipation protrusion 200 includes a heat dissipation bar 21, and a plurality of heat dissipation bars 21 are provided and arranged along the width direction of the heating plate 100, and the heat dissipation bars 21 extend along the length direction of the heating plate 100 and penetrate the two end surfaces, that is, the infrared light radiated through the protruding surface of the heat dissipation bar 21 extends obliquely in the width direction of the heating body, so that the radiation area of the heating plate 100 is expanded in the width direction of the heating plate 100. In other embodiments, the heat dissipation bar 21 may extend along the length direction of the heating plate 100 and penetrate only one end surface; or may not penetrate the end surface of the heating plate 100. In another other embodiment, the heat dissipation bar 21 may be arranged along the length direction of the heating plate 100 and extend along the width direction of the heating plate 100.
[0036] In one embodiment, the cross-sectional shape of the heat dissipation bar 21 includes a first straight line segment 211, a second straight line segment 212, and a third straight line segment 213 connected in sequence, the first straight line segment 211 and the third straight line segment 213 are both inclined to extend in a direction away from the second straight line segment 212 and toward the direction close to the heating wire, and the second straight line segment 212 extends along the width direction of the heating plate 100. That is, the cross-sectional shape of the heat dissipation bar 21 is nearly a trapezoid, wherein the second straight line segment 212 radiates infrared light to the area directly in front of the first side surface 11 and / or the second side surface 12, and the first straight line segment 211 and the third straight line segment 213 can radiate infrared light to other areas in front of the first side surface 11 and / or the second side surface 12 and in the up and down directions. In other embodiments, the cross-sectional shape of the heat dissipation bar 21 can also be configured as an arc surface.
[0037] In one embodiment, the cross-sectional shape of the heat dissipation strip 21 further includes a first arc segment 214 and a second arc segment 215. The first arc segment 214 is disposed between the first straight segment 211 and the second straight segment 212 to make a smooth transition between the first straight segment 211 and the second straight segment 212. The second arc segment 215 is disposed between the second straight segment 212 and the third straight segment 213 to make a smooth transition between the second straight segment 212 and the third straight segment 213. Since the heating plate 100 made of ceramic material needs to be formed by high-temperature firing of a clay embryo, in mass production, the clay embryo of the heating plate 100 is usually formed by a mold. Due to the properties of the clay itself, a model with a circular transition surface is easier to demold during demolding than a model without a circular transition surface, and has a lower damage rate during demolding.
[0038] In one embodiment, the heating plate 100 includes a heat dissipation groove 13, which helps to reduce the weight of the heating plate 100. The heat dissipation groove 13 is provided between two adjacent heat dissipation bars 21. In other embodiments, the heat dissipation groove 13 may not be provided.
[0039] In one embodiment, the cross-sectional shape of the heat dissipation groove 13 is configured as an arc, one end of the arc is smoothly connected to the first straight line segment 211 of a heat dissipation bar 21, and the other end of the arc is smoothly connected to the third straight line segment 213 of another heat dissipation bar 21, that is, the provision of the heat dissipation groove 13 helps to demold the heat dissipation bar 21 on the clay embryo. In other embodiments, the cross-sectional shape of the heat dissipation groove 13 may be consistent with the cross-sectional shape of the heat dissipation bar 21.
[0040] See also Figures 4 to 5 In another embodiment, the heat dissipation protrusion 200 includes a heat dissipation block 22, and a plurality of heat dissipation blocks 22 are arranged at intervals along the first direction and the second direction, and the first direction and the second direction are arranged to intersect. The infrared light radiated by the heat dissipation block 22 can extend obliquely in the length direction or width direction of the heating plate 100, so that the radiation area of the heating plate 100 is expanded in both the length direction and the width direction of the heating plate 100. Furthermore, the heat dissipation block 22 covers the first side surface 11 and / or the second side surface 12 of the heating plate 100. In other embodiments, the heat dissipation block 22 can be laid only in the preset area of the first side surface 11 and / or the second side surface 12.
[0041] In another embodiment, the planar cross-sectional shape of the heat sink 22 is configured as a circle, and the cross-sectional shape of the heat sink 22 is configured as a semi-arc shape. Since the clay model with an arc structure is easy to be formed on the mold and is not damaged during the demolding process, this arrangement makes it easy for the heat sink 22 to be formed on the clay embryo.
[0042] In another embodiment, the first side surface 11 and the second side surface 12 are both provided with heat dissipation protrusions 200, and the heat dissipation protrusions 200 are arranged one by one on the first side surface 11 and the second side surface 12. That is, the heating plate 100 can radiate infrared light in a wide range on both opposite sides. Further, on one of the first side surface 11 and the second side surface 12, the heat dissipation protrusion 200 can be a heat dissipation bar 21, and the heat dissipation protrusion 200 on the other side can be a heat dissipation block 22; or, the heat dissipation protrusions 200 on the first side surface 11 and the second side surface 12 are both set as heat dissipation blocks 22 or heat dissipation bars 21.
[0043] In another embodiment, the heating wire is electrically connected to an external power source through an electric plug structure 300, and the electric plug structure 300 is provided on the side of the heating plate 100. A charging notch 14 is provided on the peripheral side of the heating plate 100, and the electric plug structure 300 is received in the charging notch 14. The provision of the charging notch 14 helps to install and position the plug-in component that can be electrically connected to the heating element in the electric heater, and the charging notch 14 can accommodate the electric plug structure 300 and the plug-in component of the electric heater for the heating element, so as to reduce the volume occupied by the internal space of the electric heater. In other embodiments, the charging notch 14 may not be provided.
