The plane is also one of curved surfaces. The plurality of non-parallel planes are connected to form a folded surface, and the opening of the included angle of the folded surface faces back to the heating tube, which is also a condition of a convex curved surface.

In one embodiment, the number of reflective plates 301 is two, and the two reflective plates are connected to form a dihedral angle smaller than 180 degrees, and the dihedral angle is open toward the back of the heat generating tube 101. The two reflecting plates can reflect the heat generated by the heating tube to the article to be heated, so that the heat cannot be concentrated around the heating tube, the heating temperature of the heating tube is reduced, and the service life of the heating tube is prolonged. The two reflecting plates are integrally formed and can be formed by one-time stamping, so that manufacturability is improved. The two reflecting plates of the embodiment are connected to form a dihedral angle smaller than 180 degrees, the opening of the dihedral angle faces back to the heating tube, and heat generated by the heating tube is reflected in two directions, so that uniform radiation of heat in the cavity of the heating device is facilitated. In a further embodiment, the number of the reflecting plates may be three or more, and the reflecting plates may be integrally formed with the reflecting plates so that the openings face away from the heat generating tube 101.

In one embodiment, the curved surface is an arc surface. The arc surface can be in the form of a cylindrical surface or a hemispherical surface. In the case of using a cylindrical surface, a generatrix of the cylindrical surface is parallel to the axis of the heat generating tube 101. In the case of using a hemispherical surface, the outer surface of the hemispherical surface faces the heating pipe. The cylindrical surface and the hemispherical surface are adopted to radiate heat more uniformly than the folded surface.

The first direction is an axial direction of the heat generating tube 101, i.e., a left-right direction in fig. 1. The heating tube 101 may be made of various materials such as stainless steel, alloy, etc. In one embodiment, the outer shell of the heating tube 101 is a quartz glass tube, and the quartz glass tube contains a resistance wire therein, which generates heat when energized. The protective cover 104 can form a protective layer between the heating tube 101 and an external object, so that the probability of damaging the heating tube 101 by the external object is reduced, and the probability of scalding caused by false triggering of the heating tube 101 by a human hand can also be reduced. The ceramic seat 102 is integrally formed, and the ceramic seat has good heat resistance and insulating effect. The reflecting plate 301 is used to reflect the heat generated by the heat generating tube 101 into the cavity of the heating apparatus, and to heat the object to be heated in the cavity.

According to the heating component provided by the embodiment of the utility model, the curved surface protruding towards the heating tube can reflect the heat generated by the heating tube to the object to be heated, so that the heat cannot be concentrated around the heating tube, the heating temperature of the heating tube is reduced, and the service life of the heating tube is prolonged. The curved surface of the reflecting plate reflects heat generated by the heating tube to a plurality of directions, and is beneficial to uniform radiation of heat in the cavity of the heating equipment.

Referring to fig. 1, the second direction is the front-rear direction in fig. 1. The larger the width of the reflecting plate 301 in the front-rear direction is, the larger the area of the reflecting plate is, and the better the heat reflecting effect on the heating tube is. The length of the reflecting plate 301 in the left-right direction is equal to or less than the distance between the two porcelain bases 102 in order not to interfere with the connection of the porcelain bases 102 to the heating device.

In some embodiments of the present utility model, as shown in fig. 4, the shield 104 includes a first shielding plate 302 and a second shielding plate 308, the second shielding plate 308 is integrally formed with the first shielding plate 302, the second shielding plate 308 is disposed at two ends of the first shielding plate 302 along a first direction, the second shielding plate 308 is integrally formed with the reflecting plate 301, and the second shielding plate 308 is bent over the reflecting plate 301. That is, the first shielding plate 302, the second shielding plate 308, and the reflecting plate 301 of the shield 104 are integrally formed, which has advantages in that the manufacturing efficiency is improved, the manufacturability is improved, the production cost is reduced, and the production time is shortened, compared to the assembly using separate parts.

Referring to fig. 4, the first shielding plate 302 has a circular arc shape in cross section, the first shielding plate 302 surrounds the top and side surfaces of the heating tube 101, and the first shielding plate 302 is provided with a plurality of heat radiation holes 304. The heat dissipation holes 304 are separated by guardrails 303. The cross section of the first protection plate 302 is arc-shaped, and compared with the shape of the prior right-angle side, the shielding of heat is less, and the heat is prevented from being concentrated near the heating tube 101. The first shielding plate 302 surrounds the top and side surfaces of the heating tube 101, and reduces the use of materials while achieving shielding. The heat radiation holes 304 can radiate heat generated by the heat generating tube 101.

In one example, referring to fig. 5, the periphery of the heat dissipation hole 304 has a concave curved surface 309 on a surface near the heat generation pipe 101. It is to be understood that the concave curved surface 309 may be formed by punching, and the concave curved surface 309 reinforces the mechanical strength of the heat dissipation hole 304 by its shape, and on the basis of satisfying the strength, material can be saved. The concave curved surface 309 makes the surface of the shield appear more plump, improving the aesthetic appearance of the shield.

The first bending plate 305 and the second bending plate 306 are used for fixing the shield 104 and the ceramic base 102 together in a bending manner, so that the heating tube 101 cannot be separated from the ceramic base 102. In one embodiment. The connection between the first bending plate 305 and the second bending plate 306 has a notch 307. The notch 307 can save material at the connection part on one hand, and can reduce mechanical strength at the connection part on the other hand, so that an assembler can bend the second bending plate more effort-saving.

Specifically, a first end of the insert 103 is connected to a resistance wire of the heat pipe 101, and a second end of the insert 103 is adapted to be inserted into a heating device. The inner diameter of the connection hole 201 is matched with the outer diameter of the heating tube 101, and the end part of the heating tube 101 is inserted into the connection hole 201. Alternatively, the tab perforation 202 is an elongated perforation. After the second end of the insert 103 passes through the insert hole 202, it is twisted by 90 degrees so that the second end of the insert 103 is blocked outside the insert hole 202.

The ceramic seat 102 is provided with a fixing hole 205 penetrating the ceramic seat 102 along the second direction, a first bending plate 305 is inserted into the fixing hole 205, and a second bending plate 306 is abutted with the surface of the ceramic seat 102. Optionally, the fixing hole 205 is a strip hole. The first bending plate 305 and the second bending plate 306 generate elastic force by bending to abut the shield 104 against the ceramic seat 102. The bottom surface of the ceramic seat 102 is provided with an insulating block 204, the insulating block 204 surrounds the second end of the inserting sheet 103, and the second end of the inserting sheet 103 protrudes out of the insulating block 204. The insulating block 204 functions to prevent the contact between the tab 103 and the reflective plate 301 from leaking electricity.
