Description

Technical Field

[0001] This utility model relates to the field of acupuncture needle heating equipment technology, specifically a heating device suitable for acupuncture needles of various specifications. Background Technology

[0002] Fire needle heating is a traditional Chinese medicine therapy that combines the principles of acupuncture and heat therapy. It involves heating a specially made metal needle and then quickly inserting it into acupoints to achieve therapeutic effects through heat stimulation. In practice, acupuncture needle heating equipment is needed to heat the acupuncture needles for easier heating.

[0003] Current heating devices for acupuncture needles often use open flames from alcohol lamps, which are inefficient and unsafe. Furthermore, their structure is not flexible enough and cannot meet the heating needs of acupuncture needles of different diameters and depths. This results in poor applicability of the device. Based on this, we propose a new heating device suitable for acupuncture needles of various sizes. Utility Model Content

[0004] The purpose of this invention is to provide a heating device suitable for acupuncture needles of various sizes, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heating device suitable for acupuncture needles of various specifications, comprising a housing, a high-frequency generator installed at the bottom of the housing, a PLC controller and a timer installed inside the housing above the high-frequency generator, an induction coil fixed inside the housing above the PLC controller, a heating cavity matching the induction coil set at the top of the housing, a temperature sensor installed on the inner wall of the heating cavity, an adjusting seat uniformly fixed inside the heating cavity, a needle-releasing plate rotatably connected to the top of the adjusting seat, adjustable needle insertion holes symmetrically arranged at both ends of the top of the needle-releasing plate, needle diameter adjustment holes uniformly arranged on the adjusting seat, and reserved sliding openings provided on the housing at both ends of the adjusting seat, with reserved sliding rods slidably connected inside the reserved sliding openings, and depth adjustment plates fixed between adjacent reserved sliding rods.

[0006] Preferably, four adjustment seats are provided, and the adjustment seats are arranged at equal intervals on the heating cavity.

[0007] Preferably, a damping bearing is provided between the needle feeding disc and the adjusting seat at the middle position.

[0008] Preferably, an annular limiting slide rail is provided at the edge of the adjusting seat, and a limiting slider that is slidably connected to the annular limiting slide rail is welded to the bottom of the adjusting seat.

[0009] Preferably, the outer sidewall of the limiting slider and the inner sidewall of the annular limiting slide rail are both uniformly provided with anti-slip teeth.

[0010] Preferably, the needle diameter adjustment holes are arranged at equal angles on the adjustment seat.

[0011] Preferably, the outer wall of the reserved slide bar is provided with scale lines, so that the user can intuitively observe the depth of the depth adjustment plate at the bottom of the reserved slide bar inside the housing.

[0012] Preferably, the reserved sliding opening is threaded with a locking screw that matches the reserved sliding rod, so that the reserved sliding rod with the adjusted insertion depth can be locked and fixed by tightening the locking screw threaded on the reserved sliding opening.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This heating device, applicable to acupuncture needles of various specifications, optimizes its performance by incorporating a high-frequency generator. The high-frequency generator generates an alternating electromagnetic field, which in turn induces eddy currents at the needle tip via an induction coil. These eddy currents are converted into heat energy within the metal needle body, rapidly raising the needle tip temperature. The heating time is controllable within 2-3 seconds. Furthermore, utilizing the principle of high-frequency eddy current electromagnetic induction, the device can heat the acupuncture needle within 5 seconds using non-contact eddy current heating technology, saving 70% of the time compared to traditional fire needle heating. It boasts high operational efficiency, operates without open flame, and is noiseless, pollution-free, and burn-free. Its safety isolation design eliminates the risk of electric shock and cross-infection, overcoming the limitations of traditional methods. Overcoming the limitations of traditional open flame heating, the system utilizes the control function of a PLC controller, the temperature monitoring function of a temperature sensor, and the heating execution function of a non-contact eddy current heating mechanism composed of an induction coil and a high-frequency generator to achieve a better closed-loop heating function. The coordinated work of the actuator and the closed-loop feedback mechanism facilitates precise timing control. Users only need to set the time using the PLC controller and timer, and the system can automatically complete the heating process without manual intervention. It is both safe and efficient. Moreover, the closed-loop heating system and automatic output can achieve timing control, with the time adjustable arbitrarily from 0 to 60 seconds. Compared with traditional alcohol lamp heating, it is more convenient, faster, safer, pollution-free, and risk-free.

[0015] (2) The heating device applicable to acupuncture needles of various specifications optimizes its structure by setting a reserved slide bar, etc. On the one hand, the user can use the sliding connection formed by the reserved slide bar and the reserved slide bar to adjust the depth of the reserved slide bar inserted into the machine housing, and then determine the working depth of the depth adjustment plate corresponding to the bottom of the reserved slide bar by observing the scale line on the reserved slide bar. By pressing the depth adjustment plate against the bottom of the acupuncture needle, the heating requirements of different depths of needle insertion can be met. On the other hand, the user can use the rotational connection of the damping bearing, the sliding guide formed by the ring limit slide rail and the limit slider, and the anti-slip limiting effect of the anti-slip teeth to rotate the needle plate to the corresponding diameter adjustment hole on the adjustable needle insertion hole on it. This makes it easy to adjust the four needle plates to be suitable for the needle insertion heating treatment of acupuncture needles of different diameters. Thus, the device can flexibly change the needle insertion structure of different diameters and depths according to different specifications of acupuncture needles, and realize the simultaneous heating treatment of multiple acupuncture needles of different specifications, thereby enhancing its applicability.

Needle diameter adjustment holes 18 are uniformly arranged on the adjusting seat 3.

[0027] A damping bearing 19 is provided between the needle feeding plate 2 and the adjusting seat 3 at the middle position;

[0028] An annular limiting slide rail 16 is provided at the edge of the adjusting seat 3, and a limiting slider 15 that is slidably connected to the annular limiting slide rail 16 is welded to the bottom of the adjusting seat 3.

This makes it easy to adjust the four needle plates 2 to be suitable for the needle insertion heating treatment of acupuncture needles of different diameters.

[0031] Both ends of the housing 1 of the adjustment seat 3 are provided with reserved sliding openings 6. Reserved sliding rods 9 are slidably connected inside the reserved sliding openings 6. Depth adjustment plates 10 are fixed between adjacent reserved sliding rods 9.
