Description

Portable moxibustion device and control method thereof

The invention relates to a portable moxibustion device and a control method thereof.

Moxibustion is an important part of acupuncture and one of the important methods of Chinese medicine to treat diseases. It has a history of thousands of years and is of great clinical significance. The pathway of moxibustion includes the warm stimulation of acupoints during the burning process of moxa, and the pharmacological effects of the volatiles during burning of moxa.

It is stimulated by the heat and smoke generated by the burning of moxa sticks to achieve the purpose of disease prevention and treatment. This warm stimulation can cause local skin congestion, capillary expansion, enhance local blood circulation and lymphatic circulation, relieve and eliminate smooth muscle spasm, strengthen local skin tissue metabolism, and promote inflammation, adhesion, exudate, hematoma, etc. Pathological products dissipate and absorb; it can also cause the diffusion of inhibitory substances in the cerebral cortex, reduce the excitability of the nervous system, and exert sedative and analgesic effects; at the same time, the warming effect can also promote the absorption of drugs.

Most of the moxibustion apparatuses used in existing beauty institutions are large in size and complex in structure. For example, the moxibustion apparatus described in Chinese patent CN 104352351B adopts a desk-mounted or floor-mounted moxibustion moxibustion apparatus.

For example, the electric moxibustion device described in Chinese patent CN103040610B, this manual ignition and manual adjustment method is not only troublesome, but also manual ignition will cause the burning position of the moxa stick due to the difference of human operation. Uneven, smoke is formed during the ignition process, polluting the external environment. At the same time, manual adjustment of the time lag after the human body perceives it will cause the delay and instability of the temperature adjustment in the fumigation process, and it is difficult to maintain the continuity of the fumigation process, and the fumigation effect is greatly reduced.

The beneficial effects of the device are: the moxibustion device has a compact structure, a low manufacturing cost, is convenient to carry, and is convenient to use.

Since there is a temperature sensor in the fumigation hood, the temperature sensor is used to detect the current temperature of the air in the fumigation hood; the moxibustion device also includes an air input mechanism and a controller, and the air input mechanism and the controller are borrowed The controller is connected to the power supply by a wire; the controller is electrically connected with the ignition coil, the air input mechanism and the temperature sensor, and the temperature sensor feeds back the current temperature of the air in the fumigation hood to the controller.

When the temperature rise timing module reaches the end time and the current temperature detected by the temperature sensor in the fumigation hood has not risen within the end time, the moxibustion end prompt unit of the moxibustion device emits a prompt sound to prompt the moxibustion process end.

The beneficial effect of the method is that the method can monitor the temperature in the fumigation hood in real time, and adjust the air inlet volume in real time according to the monitored temperature, so that the user can obtain a better experience.

Since the heating timer module and the temperature sensor work together to determine the end of moxibustion, the user is reminded in time without disassembling the moxibustion device for confirmation. Makes use more convenient.
