The invention will be further described below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the structural representation of microwave diathermy machine;
Fig. 2 is the circuit diagram of amplifier (7);
Fig. 3 is the structural representation of thermostat (9);
Fig. 4 is the circuit diagram of ac zero-crossing detection circuit (12);
Fig. 5 is the structural representation of irradiator (1).
In the drawings, (1) is for having the irradiator of critesistor.(31) be the inner wire of irradiator (1), (32) are dielectric layers, and they are that coaxial cable (2) is peelled off the metallic conductor (31) and dielectric layer (32) that stays behind the screen layer, and its length is decided on the size of focal zone.On dielectric layer (32), the metal forming (33) of the narrow strip that width is about 5 millimeters, for example silver-plated Copper Foil, by certain pitch, for example 6.5 millimeters, be wrapped in tightly the section of stripping out go up, in metal forming (33) and coaxial cable (2) screen layer intersection, both are welded.With poly tetrafluoroethylene the helical antenna that makes is tightly wrapped then.Then go up the high-intensity enamel-covered wire of fine welding wire at the critesistor (34) of having cut short lead-in wire, promptly the signal lead of temperature detector (5) places critesistor (34) on the centre position of metal forming (33) afterwards, and with low-loss medium with its bed hedgehopping.Make the middle part of signal lead (5) along metal forming (33); draw along the spiral winding; and enter coaxial cable (2) afterwards leaving helical antenna; continue to adopt spiral way to twine; cause the end of irradiator protective casing (35) always; the length of sleeve pipe (35) is decided on the position of focus, and present embodiment is 700 millimeters.
The coaxial cable of irradiator (2) is connected with microwave power source (4) by radio frequency connector (3), the signal lead of temperature detector (5) is connected with amplifier (7) through connector (6), and the other end of amplifier (7) then is connected with thermostat by connector (8).Critesistor (34) on the irradiator (1) is presented the temperature signal that records to amplifier (7) through signal lead (5), amplifier (7) converts temperature signal to same voltage signal values and delivers to the single-chip microcomputer that has A/D converter (11) in the thermostat (9), A/D converter converts this voltage analog to after the digital quantity, in single-chip microcomputer, compare with the temperature value of setting, then carry out ratio, integral operation, export a controlled quentity controlled variable according to operation result ac solid relay (10) is controlled.Ac zero-crossing detection circuit (12) one termination alternating current power supplys (13) in the thermostat (9), the other end connects single-chip microcomputer (11), makes control and the AC synchronous of single-chip microcomputer to solid-state relay (10).Can continuously change the supply voltage of the high-tension transformer in the microwave power source (4) by ac solid relay (10) from the control signal of single-chip microcomputer (11), thereby changed the microwave tube output, promptly changed the microwave power of irradiator (1) to the focal zone dispensing, the temperature that equals to set until the temperature that is heated the district, the controlled quentity controlled variable of single-chip microcomputer (11) output goes to zero, and above-mentioned control procedure just brings to a temporary end.
Above-mentioned thermostat (9) also can be made of single-chip microcomputer (14), A/D converter interface (15) and ac zero-crossing detection circuit (12), and the described as shown in Figure 3 single-chip microcomputer of its connected mode (14) can be selected the MCS-51 single-chip microcomputer for use.
