In addition, under the elastic deformation action of the buffer sheet 54, the first buffer plate 51, the second buffer plate 52, the first shell 1 and the second shell 2 connected with the first buffer plate and the second buffer plate are further away from each other, the distance is restored, permanent deformation is avoided, and the service life is ensured. The setting of buffer board for get into the low temperature air current between first buffer board 51 and the second buffer board 52 constantly changes the flow direction, produces the vortex easily, improves the contact probability of air current and first buffer board 51, second buffer board 52 to and the probability that the air current reentry first casing 1 top space, thereby help improving the heat transfer effect of first casing 1 bottom terminal air current and patient's head. In addition, the buffer sheet 54 is matched with the U-shaped structure of the buffer connecting piece 5, so that gas retention is prevented, surrounding gas is driven to flow by airflow disturbance, and local heat exchange failure is prevented.
In addition, evenly lay the air vent on the buffering bent plate 53, so, the inside low temperature air current of first casing 1 can outwards be discharged through the air vent on the buffering bent plate 53, so can avoid low temperature air current direct laminating patient skin to flow, reduce the stimulation to the patient body surface, avoid the patient to produce the discomfort. In addition, the provision of the cushion sheet 54 can also reduce or slow down the flow rate of the air flow that can be discharged from the inside of the case, so that energy consumption can be saved, and on the other hand, can also reduce the uncomfortable feeling caused by the impact of the low-temperature air flow on the upper part of the limb of the patient, for example, can prevent the low-temperature air from flowing through the portion that quickly impacts the shoulder blade of the patient, and the like. The buffer sheet 54 is fitted with the vent hole, and can also achieve a filtering effect on the exhaust air flow, and the annular hair and the like entrained in the air flow are intercepted by the buffer plate and collected in the buffer connector 5, thereby preventing the vent hole from being blocked.
While the foregoing embodiments have been described in detail in connection with the embodiments of the invention, it should be understood that the foregoing embodiments are merely illustrative of the invention and are not intended to limit the invention, and any modifications, additions or substitutions made therein without departing from the spirit and scope of the invention.
