Embodiment Construction

[0015] refer to Figure 4 , the waveguide cavity is formed by docking the front cavity 22 and the rear cavity 21, the front cavity 22 and the rear cavity 21 are made of metal aluminum die-casting, and attention should be paid to die-casting the magnetron input hole 11 and the radiation hole 12 together , the butt joint of the front cavity 22 and the rear cavity 21 is located at the center line of the waveguide cavity and is parallel to the transmission direction of the electric current generated by the electromagnetic wave transmission when it runs inside the waveguide cavity, and finally they are bolted (not shown) connected into one.

Abstract

Wave-guide cavity in use for microwave sulfur lamp is composed of front cavity and back cavity butt jointed each other. There is an input hole of magnetron on left side at base, and there is an irradiation hole on right side at top. Since fabricated slot is located at midline of the wave-guide cavity, when surface current generated by electromagnetic wave runs inside, the disclosed wave-guide cavity does not generate phenomena of striking fire at the fabricated slot so as to raise safety as well as reduce wastage of energy.

Description

1. Technical field [0001] The invention relates to a waveguide cavity for a microwave sulfur lamp, in particular to a waveguide cavity for a microwave sulfur lamp which is not easy to spark from a gap. 2. Technical Background [0002] Microwave sulfur lamp is a new type of light source that uses a new light-emitting mechanism to emit light. It has the advantages of energy saving, long service life, good light color and less pollution. Its light emitting process is as follows. [0003] refer to figure 1 , figure 2 . The sulfur lamp bulb 2 is placed in the resonant cavity 1, and is rotated by the motor 6 through the lamp handle 8, and the fan 10 plays a cooling role; the waveguide cavity 3 is formed by connecting the lower cavity 13 and the upper cover 9; the magnetron 5 The output part 4 is inserted into the waveguide cavity 3 through the magnetron input hole 11 on the left side of the lower cavity 13, and the electromagnetic wave emitted by it is radiated to the sulfur ...
