Description

Technical Field

[0001] The utility model belongs to the technical field of physical therapy devices, and in particular relates to a portable smokeless moxibustion device which is convenient for temperature adjustment. Background Art

[0002] While using the gentle heat and light radiation of the moxibustion fire to penetrate deep into the acupuncture points, moxibustion also exerts the pharmacological effects of the aromatic and warming properties of moxa leaves, thereby unblocking the meridians, promoting the circulation of qi and blood and metabolism, adjusting the balance of yin and yang in the human body, and preventing and treating diseases. In the traditional moxibustion operation process, moxibustion therapy usually relies on others to perform the moxibustion, which is time-consuming and labor-intensive, and the control of the moxibustion temperature is poor, which poses safety hazards such as scalds and burns. At the same time, the high concentration of moxa smoke also increases the risk of respiratory diseases in the recipient.

[0003] Many medical device developers and clinical workers are committed to developing efficient and smokeless moxibustion equipment. The patent with application number CN202120894306.1 discloses a moxibustion box, including an outer shell and an inner shell both of which are provided with an air inlet grid. The outer shell includes an upper shell and a lower shell that are movably connected. The upper shell is an adjustment mechanism that can adjust the amount of air in and out. A filter material is provided between the inner shell and the outer shell. The filter material includes a first filter screen and a second filter screen. The first filter screen is buckled above the inner shell, and the second filter screen is provided between the inner shell and the lower shell of the outer shell. The patent with application number CN202120642464.8 discloses a temperature-adjustable smokeless moxibustion box, including an adjustable base, a moxibustion box body and a ventilation top cover. The moxibustion box body includes a cylinder, a safety net layer arranged at the lower part of the cylinder, and a support net layer and an ultra-fine flame-retardant fiber net at the upper part. An moxa stick holder is provided at the bottom of the support net layer. The two moxibustion boxes disclosed in the above patents can adjust the amount of air entering and exiting by rotating the upper shell, and the distance between the moxa stick and the moxibustion part by rotating the adjustable base. Both can adjust the temperature of the moxibustion. However, the temperature of the former changes slowly when adjusting, and the latter is not easy to position when adjusting. In addition, the moxibustion box is provided with a smoke filter material between the sandwich structure at the vent, so that the smoke generated by the burning of the moxa stick needs to be filtered by the smoke filter material before being discharged. In order to prevent smoke leakage and realize smokeless moxibustion, it means that all the vents of the moxibustion box need to be wrapped, resulting in an increase in the air exchange resistance between the moxa stick combustion chamber and the outside world. For existing smokeless moxibustion boxes, especially for moxibustion boxes that use vents to adjust the moxibustion temperature, reducing the vent means that the utilization area of ​​the smoke filter material will decrease, which accelerates the failure of the smoke filter material. After a while of moxibustion, smoke will be generated, and it is easy to cause the moxa stick to self-extinguish due to insufficient oxygen in the moxa stick combustion chamber. Utility Model Content

[0004] Based on the deficiencies in the prior art, the purpose of the utility model is to provide a portable smokeless moxibustion device with convenient temperature adjustment.
