[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] The utility model aims to provide a microwave physiotherapy instrument acupuncture probe to solve the problems existing in the prior art, so that the temperature at the center of the spiral coil is the highest, forming a small dot acupuncture effect, and the temperature diffused outward from the center point becomes lower and lower, forming a moxibustion effect, thereby achieving the therapeutic effects of acupuncture and moxibustion at the same time.
[0030] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0031] Embodiment 1:
[0032] like Figure 1 to Figure 4 As shown, this embodiment provides a microwave therapy instrument acupuncture probe, including a housing 1 and a spiral coil 2 placed inside the housing 1 in a vortex shape; a bottom plate with a connector 3 is provided at one end of the housing 1, and a Teflon sheet 4 for acting on the human body is provided at the other end. The connector 3 is an N-KF connector 3, which is fixed to the housing 1 by bolts, one end of which is located outside the housing 1 and is used to connect the microwave therapy instrument, and the other end of the connector 3 is located inside the housing 1 and is connected to the middle end of the spiral coil 2; along the radial direction of the spiral coil 2, the interval between adjacent coils gradually increases from the inside to the outside, that is, from the inside to the outside, the diameter of the coils in the spiral coil 2 becomes larger and larger, and the distribution becomes more and more sparse.
[0033] Furthermore, in this embodiment, the middle end of the spiral coil 2 has an extension portion 5 perpendicular to the plane where the spiral coil 2 is located, and the extension portion 5 is welded to the joint 3 .
[0034] In this embodiment, the inner surface of the bottom plate is adhered with a foam gasket 6 by cloth-based double-sided tape, and the middle of the foam gasket 6 has a through hole 7 to facilitate welding the extension part 5 and the joint 3; the outer ring of the spiral coil 2 is bonded and fixed to the foam gasket 6 by cloth-based double-sided tape.
[0035] Furthermore, the upper part of the spiral coil 2 is covered with an EPE gasket 8 , and the Teflon sheet 4 is located above the EPE gasket 8 ; the Teflon sheet 4 is fixed to the end of the housing 1 by a fixing ring 9 , and presses the EPE gasket 8 .
[0036] The total length of the spiral coil 2 is the sum of the effective length of the spiral coil 2, the extension 5 and the winding loss of the spiral coil 2. The effective length of the spiral coil 2 is an odd multiple of 12.3 mm, a wavelength of the microwave therapy device. The effective length here refers to the total length of the coils in the same plane of the spiral coil 2. After the spiral coil 2 is wound and welded to the joint 3, the end of the extension 5 needs to be polished and smoothed, which will cause winding loss. Of course, winding loss may also come from other situations. The length selection of the spiral coil 2 in this embodiment is shown in Table 1:

[0039] Table 1
[0040] In this embodiment, after the probe is connected to the microwave therapeutic apparatus, the thermal sensing diagram of the probe in various graphic modes can be obtained, such as Figures 5 to 10 As shown, it can be seen that the microwave frequency energy generated by the spiral coil 2 is concentrated at the midpoint, and the frequency energy decreases radially from the inside to the outside, thereby causing the thermal effect generated by the human body to become lower and lower from the center point to the outside, so that the temperature is highest at the center point of the spiral coil 2, forming a small dot acupuncture effect, and the temperature diffuses lower and lower outward from the center point, forming a moxibustion effect. Therefore, the probe in this embodiment can simultaneously play the therapeutic effects of acupuncture and moxibustion.

The wire reel is a desktop structure with an adjustable speed motor at the bottom. The upper end of the motor is connected to a rotating fixed disk, and the winding mold is fixed through two holes. A coil winding limit plate is set 12 mm above the winding mold fixed disk, and an adjustable structure is set on it to facilitate winding. A spiral wire groove is set on the winding mold, and the spiral wire groove is adapted to the shape and size of the spiral coil 2.
[0044] The winding mold is made of steel plate, the width of the spiral groove is 2.3mm, and the depth of the spiral groove is 2.17mm.

The inner end of the spiral groove is provided with a through hole with a diameter of 3mm for inserting the oxygen-free copper wire, and the bottom of the spiral groove is provided with extraction holes at intervals, and the aperture of the extraction hole is 2mm. After the heating of the spiral coil 2 is completed, the winding mold can be ejected from the extraction hole using a thin metal rod.
[0045] Take an oxygen-free copper wire with a diameter of 2mm, take an 8mm diameter wire at one end and bend it vertically 90°, and then bend it horizontally 90°; insert the bent oxygen-free copper wire vertically to the lower end into the central through hole of the winding mold, and rotate the bend to fit the innermost circle of the winding mold; open the continuously variable speed electrode of the wire reel, and slowly wind the oxygen-free copper wire into the winding mold.
[0046] The cable reel is a conventional device in the art, and its structure and use method are well known to those skilled in the art, so they are not described in detail in this embodiment.
[0047] S2: After winding is completed, the winding mold is removed from the wire reel and placed in a resistance heating furnace for heating. The temperature control range is 200℃~500℃ and the heating time is 2 hours.
[0048] S3: After the heating is completed, the spiral coil 2 is taken out.
[0049] S4: Fix the joint 3 on the bottom plate of the shell 1 and glue the foam gasket 6; weld the spiral coil 2 to the joint 3, and glue the outside of the spiral coil 2 to the foam gasket 6; cover the spiral coil 2 with the pearl cotton gasket 8 and the Teflon sheet 4 in sequence, and fix the Teflon sheet 4 with the fixing ring 9 to complete the preparation of the acupuncture probe of the microwave therapy device.
[0050] Adaptive changes made according to actual needs are all within the protection scope of this utility model.
[0051] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
