[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] One embodiment of the present invention provides an electromagnetic induction heating device for acupuncture needles, such as Figure 2 As shown, the heating device includes an electromagnetic controller 1, an electromagnetic heating coil 3 connected to the electromagnetic controller 1 via a wire 2, and a clamping component 4 connected to the electromagnetic heating coil 3 for clamping the needle body 52. ​​The electromagnetic heating coil 1 is used to heat the needle handle 51 without contacting the needle handle 51.

[0026] Among them, the material of acupuncture needles is magnetic conductive metal material; the electromagnetic controller, also known as the electromagnetic heating controller, is a device that uses the principle of electromagnetic induction to convert electrical energy into thermal energy; the electromagnetic controller rectifies 220V, 50 / 60Hz alternating current into direct current, and then converts the direct current into high-frequency high-voltage electricity with a frequency of 20-40KHz; the high-speed changing high-frequency high-voltage current flowing through the electromagnetic heating coil will produce a high-speed changing alternating magnetic field. When the magnetic lines of force in the magnetic field pass through the acupuncture needle, countless small eddy currents will be generated in the acupuncture needle, causing the acupuncture needle itself to heat up at high speed, thereby achieving the purpose of heating the acupuncture needle.

[0027] Among them, the ratio of the inner diameter of the electromagnetic heating coil to the diameter of the needle handle is 3-6:1, which can improve the heating effect and at least 1 / 3 of the length of the needle handle should penetrate into the electromagnetic heating coil.

[0028] The heating device defined in the present application does not come into contact with acupuncture needles, is not prone to burns, and has high heating stability and is not easily affected by the environment.

Preferably, the protrusions are threads, and the two groups of threads have the same direction.

[0033] By setting the cylindrical clamping area, the clamping points between the clamping component and the needle body are increased, the clamping effect is improved, and the convex part is set to reduce the heat conduction of the clamping part. In particular, the effect is more significant when two sets of threads are set in the same direction.

That is, the size of b and c is greater than a. The steel balls, springs, and buffer columns introduced in this application are all made of very light materials and will not increase the mass of the clamping components too much.
