Description

Infrared magnetotherapeutic instrument

The present invention relates to magnetic therapy and radiation is treated, is a kind of medical health apparatus that infrared ray and magnetic field are combined into one.

The inventor in 1986 to Patent Office of the People's Republic of China application and to be awarded a kind of patent No. be " Magnetic and infrared therapeutic apparatus " patent of 86204070.1.Its main feature is that this instrument is provided with infrared radiation and electromagnetic field two cover systems simultaneously in a housing, cause when the treatment head is distinguished near (touching) human body is ailing, under the warm radiation parameter of infrared waves, " acupuncture, massage and adjusting " effect by rotating excitation field, make that skin is warm, local organization is lax, telangiectasis, adjusting bioelectric potential and function of nervous system, with microcirculation improvement, promote pathological product to absorb, eliminate body fluid circulatory disturbance, remove muscle spasm, promote tissue regeneration, play the effect of dredging the meridian, a surname's inducing QI blood, YIN and YANG balance regulating.Its primary structure is, is provided with the infra-red radiation assembly of being made up of infrared radiation ceramic sheet, PTC heating element heater in the treatment head, and by the rotary magnetic assembly of permanent-magnet synchronous micro motor for driving permanent magnet rotation, both closely are contained on the frame at phase; The Control Component of this Magnetic and infrared therapeutic apparatus is made of switch, current-limiting resistance, display lamp and electric fuse.When opening switch, PTC heating element heater heating ceramic sheet gives off the infrared ray of certain wavelength, and simultaneously, the permanent magnet rotation of micro motor for driving more than two can be treated or keep healthy the ailing district of human body.The Magnetic and infrared therapeutic apparatus of this structure, it is comparatively convenient to have operation in actual use, the characteristics that are suitable for individual autotherapy, treatment, health-care effect is also better, its weak point is the work of being everlasting under the hot state of micro machine and permanent magnet, the heat that sends when the PTC heater element reaches setting value and when working long hours, phenomenon can appear killing in the micro machine main shaft, and can influence the performance of permanent magnet; When the unskilled operational approach of user or inadvertent are forgotten shutdown, can scald pain skin, even make that cabinet is softening to be damaged.If set the heating temp of PTC heater element lowlyer, do not fit into the requirement of variant area or different people again, influence result of use.

The objective of the invention is existing Magnetic and infrared therapeutic apparatus is improved, with the heated condition of control PTC heater element, and the micro machine of special-purpose this machine of improvement, make it to improve operating reliability, promptly improve the febrile state of existing Magnetic and infrared therapeutic apparatus on the whole, improve its quality, improve service condition.

For achieving the above object, the present invention has at first offered the arc ventilation slot that connects in the micro machine position is installed on the housing base, to improve the working condition of housing head; In Control Component, be provided with a thermosensitive switch elements again, it can be arranged in the control circuit of infrared radiation assembly, also can be arranged in the circuit behind the gauge tap, makes when the ambient temperature of housing head surpasses certain value just disconnecting circuit, when being lower than this value, recover energising.The present invention has done improvement to the main shaft bearing system of the micro machine of drive permanent magnet rotation in the rotary magnetic assembly, promptly two fixed sliding bearings are made into two spherical plain bearings, and be positioned at the assembly axis place of holding (being electric machine casing and cover plate centre) on cover plate at electric machine casing the lubricated pad of oil-containing is set, fix with a decorative cover, with rotation and the lubricating condition of improving main shaft.

After the present invention has done as above to improve, have the characteristics of temperature control, improved temperature condition on the whole, and, because the moving rule of hot and cold air-flow also helps Btu utilization; Thermosensitive switch elements can make things convenient for use according to the duty of the ambient temperature robot brain device of housing head, has improved safety, simultaneously, has prevented that micro machine from working under superheat state; The electric machine main shaft bearing arrangement from the tonality structure, made things convenient for the assembly technology of motor, still run well when motor is worked under the ambient temperature conditions of higher, prevent to burn out motor coil because of killing.

Description of drawings:

Fig. 1 is a structural representation of the present invention.

Fig. 2 is the vertical view of the present invention's housing bottom.

Fig. 3 is the line assumption diagram of used Control Component in the embodiment of the invention.

Fig. 4 is the structural representation of the used micro machine of the present invention.

Embodiments of the invention as shown in drawings.This is a kind of portable infrared magnetotherapeutic instrument.Seen that by Fig. 1 the present invention is by infrared radiation assembly 2, rotary magnetic assembly 3 and Control Component 4 are formed, and the three is placed in the same housing made from ABS plastic 1.Be shaped on the radial air vent 16 except that opening on the housing bottom 5, also on the bottom surface of its installation micro machine, have curved air vent 15(and see Fig. 2) along the head outer ring.Infrared radiation assembly 2 and rotary magnetic assembly 3 are installed on the pillar 6 of housing 1 head.Infrared radiation assembly 2 comprises infrared radiation ceramic sheet 18, PTC heating element heater 10, electrode 9 and porcelain base 7.Topped heating element heater 10 two sides to be clamped between infrared radiation ceramic sheet 8 and the porcelain base 7 behind the electrode 9 and to be fixed on the pillar 6; Rotary magnetic assembly 3 comprises 600 rev/mins of permanent-magnet synchronous micro machines 14, transmission axle bed 11, transverse arm 12 and two neodymium-iron-boron permanent magnets 13.Be connected in the electric machine main shaft axle head by transmission axle bed 11 after two blocks of permanent magnets 13 are arranged on transverse arm 12 two ends, this micro machine 14 that permanent magnet 13 is housed also is contained on the pillar 6, and makes the porcelain base of the as far as possible close radiation assembly of permanent magnet 13 working surfaces.After assembling radiation assembly 2 and rotary magnetic assembly 3 thus, in the outside mask of infrared radiation ceramic sheet 8 outer housing with a band mesh.Control Component 4 in the present embodiment is installed in the handle of housing 1.
