Problems solved by technology

The heater with this structure still has the following disadvantages. Each heating element is only supported at both ends, and it is easy to break due to external force. Multiple heating elements are installed side by side in the same glass tube. The electrical connection is cumbersome and difficult, and the heating element is in the shape of a round rod, and the connection between it and the wire must also be made through a coil-shaped connection part, and the structure is complicated

Embodiment 1

[0017] Such as figure 1 Shown, heating element 1 of the present invention, it is the long ruler thin plate shape with uniform cross-sectional area, and its length direction is longitudinal side 2, and its width direction is transverse side 3, and its two ends are provided with lead wire connecting portion 11, and in two On the longitudinal side 2, openings 4 are arranged facing each other and spaced apart from each other. Between adjacent openings 4 , the distance between adjacent sides is the same as the distance between the vacant parts of the openings 4 .

Embodiment 2

[0019] Such as figure 2 , image 3 As shown, the connection between the heating element 1 and the wire described in Embodiment 1 is through a clamping metal piece 6, and the connecting clamping metal piece 6 is composed of two clamping plates 8 and used to press the clamping plate 8 The open end of the "U"-shaped clip 9 is folded outward to form a protruding wing 10, which is convenient for fixing two "U"-shaped clips to cooperate with each other, and fix the clamping plate 8 and the heating element 1 . One end of the clamping plate 8 close to the heating element 1 is folded outward to form a heat shielding plate 7 . Separate the heating area from the wire connection area to prevent heat loss. In actual use, the heat shield 7 and the protruding wings 10 can be made into different geometric shapes.

Embodiment 3

[0021] Such as Figure 4 As shown, the heating element 1 described in Embodiment 2, which is connected by the clip-type metal piece 6 and the wire, is packaged in the glass tube 5 to form a heater. The wire passes through the top of the glass tube 5, and the glass tube 5 is sealed with an inert gas. The body heating element 1 can energize the heating element 1 in the glass tube 5 by leading out the wire outside the glass tube 5 . Such as Figure 5 As shown, the inner diameter of the glass tube 5 for encapsulating the heating element 1 is consistent with the width of the heating element 1 , that is, the lateral side 3 . In this way, the long side of the heating element 1 is firmly supported on the inner wall of the glass tube 5, which can reduce the vibration effect of external force and ensure the service life.

Abstract

This invention provides a heat body and heater. Wherein, the heat body is long-size thin plate with even cross section and long direction as vertical side; arranging opposite switches on vertical sides with space; the heater is formed by packaging the heat body into a glass tube, a metal member connects the heat body ends and wires. The invention changes the heat body impedance value without any change to original physical strength and the zigzagging loop, has high efficiency and utility, enlarges contact area, and ensures the service time.

Description

technical field [0001] The invention relates to a heating device, in particular to a heating body and a heating device manufactured using the heating body. Background technique [0002] The technology of using conductors to energize to emit light and heat is well known. Its main method is to seal the conductors in a glass tube (quartz tube) filled with inert gas. Conducting electricity through a conductor generates heat. To increase the generation of heat energy, it is necessary to increase the resistance value of the conductor. At present, the electrical impedance of the conductor is generally adjusted by reducing the cross-sectional area of ​​the conductor or adding an adhesive to the conductor material. Reduce the cross-sectional area of ​​the conductor, such as a tungsten filament bulb, which uses a spiral filament, but the spiral filament is too thin and easily broken, and due to the uneven pitch of the spiral, it is easy to generate uneven he...
