This invention provides a warm acupuncture device with temperature control, belonging to the field of warm acupuncture technology. It includes acupuncture needles, a fixed tube, a movable tube, a fixed groove, a fixed crossbar, an upper connecting rod, and an inclined rod. The invention utilizes a movable tube, a mounting frame, a fixed groove, and a pressing plate. By pressing the lower end of the pressing plate inward, the clamping block penetrates the fixed tube, releasing the acupuncture needle. At this point, the movable tube and mounting frame can be lifted upward, separating the acupuncture needle from the moxa stick and reducing the needle's temperature. This achieves direct and rapid temperature control by allowing the acupuncture needle to contact and separate from the burning moxa stick. This solves the problem of existing warm acupuncture temperature control devices that regulate temperature by controlling the number of vents, which is slow and affects treatment effectiveness. Furthermore, the acupuncture needles inserted into the skin, bearing a large load, are not stable enough when supported solely by the needles. Additionally, ash can fall from the vents of the container holding the burning moxa stick, potentially burning the patient.
