Description
Technical Field
The utility model relates to an ultra-low temperature treatment field, concretely relates to liquid nitrogen cryotherapy cabin that possesses inner loop and low energy consumption.
Background
Cryotherapy is a method of treating diseases by bringing a medium below body temperature into contact with a human body to lower the temperature of the body. The transient deep low temperature can excite the nervous system, and the effect is opposite if the temperature is too long; the cold action is applied to the local part to enable the blood vessels to contract and then expand, thereby being beneficial to improving the local circulation; the cold can deepen breath, and is clinically used for high fever, early soft tissue injury and neurosis, and also is commonly used for health care and improving the body resistance. The cold therapy is a method of acting a refrigerant on the human body to reduce the local or systemic temperature temporarily, thereby achieving the purposes of treating diseases and strengthening physique.
Prior art CN105167838B discloses an ultra-low temperature cold therapy apparatus, including gas storehouse and cold therapy cabin, be provided with air inlet and gas vent between gas storehouse and the cold therapy cabin, the gas storehouse includes liquid nitrogen tank, gasbag, liquid nitrogen cavity, turbo fan and gas storehouse gas vent, the motor of breathing in is impressed the liquid nitrogen into the liquid nitrogen cavity through the business turn over gas of control gasbag, and the liquid nitrogen in the liquid nitrogen cavity vaporizes into nitrogen gas under turbo fan's effect, and nitrogen gas gets into the cold therapy cabin through the air inlet. The cold therapy cabin is provided with a gas inlet for gas inlet, a lifting platform exhaust port for exhaust positioned below the gas inlet, a second exhaust port positioned above the gas inlet, and a first exhaust port positioned between the gas inlet and the second exhaust port and used for recovering nitrogen, the nitrogen enters the cold therapy cabin through the gas inlet, one part of the nitrogen is discharged from the lifting platform exhaust port and the second exhaust port, one part of the nitrogen is recovered from the first exhaust port, and the other part of the nitrogen is remained in the cold therapy cabin.
In the prior art, one of the exhaust ports for exhausting nitrogen to the atmosphere, namely the exhaust port of the lifting platform, is positioned below the air inlet, the temperature of the gas entering the cryotherapy cabin from the air inlet is greatly lower than the normal temperature, and the lower the temperature of the gas, the higher the density of the gas, the temperature of the gas which just enters the cryotherapy cabin falls to the bottom of the cryotherapy cabin and is positioned near the exhaust port of the lifting platform due to the higher density of the gas and is exhausted by the exhaust port of the lifting platform, so that when the cryotherapy cabin is cooled, enough low-temperature nitrogen is lacked to cool the cryotherapy cabin, the cooling time of the cryotherapy cabin is increased, the demand of the low-temperature nitrogen is increased, the overall energy consumption of the cryotherapy cabin is increased, and the service performance.
Meanwhile, in the mentioned "circulation" of the prior art, although the fan is provided in the scheme, the fan is only used for fully contacting the liquid nitrogen in the liquid nitrogen cavity with air and then accelerating the vaporization of the liquid nitrogen, the vaporized gas enters the cryotherapy cabin under the limit of each cavity wall and the conduction of the air inlet, and the fan does not have any contact with the gas in the cryotherapy cabin. Therefore, the prior art can only continuously feed air from the air inlet to increase the volume of air inside the cryotherapy chamber, so that the air near the first air outlet is squeezed into the first air outlet, and then the air passing through the first air outlet is recycled into the air bin. Because the recovered gas is positioned above the gas inlet, the prior art not only discharges the low-temperature gas through the exhaust port of the lifting platform, but also recovers the high-temperature gas, and the gas circulation performance is extremely poor; and because the gas near the first exhaust port can only be squeezed into the first exhaust port by increasing the volume of the gas, the gas farther away from the exhaust port or the gas inlet has poor or even no fluidity, the uniformity of the temperature in the cabin cannot be realized smoothly, and the temperature in the cabin can only be uniform and reduced by waiting for the 'molecular random motion' performance of the gas and the long-term waiting.
