Description

[Technical field] physiotherapy The invention relates to a physical therapy device, in particular to a hot air physical therapy device and a hot air physical therapy instrument. [Background technology] In recent years, with the accelerated pace of life and the increase in work pressure, more and more people are suffering from pain in the shoulder and neck. Traditional shoulder and neck massage products mainly include two methods: electrical stimulation massage and physical force massage. Electrical stimulation massage stimulates muscles through electric current to cause them to contract, thereby achieving the effect of massage; physical force massage uses mechanical devices to simulate human hands for force massage, such as vibration massage and percussion massage. However, both methods have certain limitations, such as electrical stimulation may cause discomfort, and the strength and depth of physical massage are difficult to accurately control.

[0003] The working principle of heat therapy is to increase the temperature of the heated part and promote blood circulation and blood flow to the heated part, which can relieve muscle stiffness or soreness. Heat therapy can be divided into dry heat and moist heat. Traditional moxibustion, hospital physiotherapy equipment and sunbathing are all dry heat therapies; while Chinese medicine fumigation, hot water bath, soaking, hot compress, etc. are moist heat therapies. At present, some massage products on the market are combined with heat therapy, such as integrated infrared generators, which use the warming effect of infrared rays to promote blood circulation. However, since the range of infrared heat therapy is often concentrated and the temperature is difficult to control, too high a temperature can easily cause skin burns, and some people may have an allergic reaction to infrared rays. [Summary of the invention] In view of this, the technical problem to be solved by the present invention is to provide a hot air therapy device and a hot air therapy instrument, which generate hot air and guide it to the shoulders and neck and other parts of the human body for heat therapy, so as to overcome the shortcomings of existing therapy instruments.

[0005] In the first aspect, in order to achieve the above-mentioned purpose of the invention, the present invention provides a hot air therapy device, comprising: The heating tube has openings at both ends, one end is the air inlet end, and the other end is the air outlet end; An air preheating chamber, located inside the air inlet end and having an air outlet; A preheating module, disposed in the air preheating chamber and adjacent to the air outlet; A main heating module is suspended in the heating cylinder and located inside the air preheating chamber; A fan, arranged at the air outlet end of the heating cylinder; An air guide pipe connected to the air outlet end of the heating tube and having an inner diameter smaller than that of the heating tube; A temperature measurement module is arranged at the outlet of the air duct; The controller is respectively connected to and controls the preheating module, the main heating module, the fan and the temperature measuring module.

[0006] In a second aspect, in order to achieve the purpose of the aforementioned invention, the present invention provides a hot air therapy apparatus, which is equipped with the hot air therapy device as described in the first aspect.

[0007] The advantages of the present invention are: the hot air therapy device of the present invention generates hot air by heating the air and is applied to the therapy products, so as to achieve the thermal therapy effect, the temperature is easier to control, the hot air is easy to guide to the required part, and can act on a larger range of human body, and there is no allergic phenomenon, thereby overcoming the shortcomings of the existing physiotherapy devices. And the use of a double heating structure of preheating and main heating can shorten the heating time and improve the heat preservation effect. The present invention also provides multiple air volume adjustment functions (adjustment of the second adjustment hole of the air intake regulating valve, elastic expansion adjustment of the preheating module, and speed adjustment of the fan), so that each link can adjust the air intake, thereby more accurately adjusting the required temperature of the outlet air, making the thermal therapy effect better and preventing burns. Furthermore, the present invention also provides a swing module to further expand the scope of thermal therapy.
