Further, the heat-conducting layer covers the hose 220 in the first region 201, thereby improving the heat transfer efficiency of the first region 201.

In the single blanket, according to the needs of health, the operating condition of switching-over valve 140 is switched over, can exchange the flow direction of liquid in hose 220 to exchange the position of heating subregion, reach different physiotherapy effects or sleep and experience.

Of course, the waist area and the foot area can be respectively arranged on the blanket body 210 to correspond to the physiological characteristics of the human body, the hose 220 can be arranged in the waist area firstly and then in the foot area, the liquid flowing into the hose 220 firstly flows through the waist area and then enters the foot area, the waist and then the feet of the human body are warmed, the temperature requirement of the waist is preferentially met, and the temperature-adjustable blanket is suitable for the requirements of female dysmenorrhea and cold uterus.

During sleeping, the heating of the feet is beneficial to promoting the blood circulation and the body relaxation of the human body and promoting the human body to rapidly enter a sleeping state, so the heating of the foot area has the function of promoting the sleeping, and the mode is common for men and women.

The female uterus cold or menstrual period heats the uterus part, which is beneficial to alleviating menstrual symptoms and has a certain effect of improving the uterus cold, therefore, the heating of the waist area is beneficial to alleviating the female menstrual symptoms and the uterus cold, and the mode is more effective for the female.

Fig. 4 shows the directional control valve in a first operating state, fig. 5 shows the directional control valve in a second operating state, in which the arrow A1 points to the waist region and the arrow A2 points to the foot region.

In fig. 4, the fluid enters the hose 220, flows through the waist region and the foot region in sequence, and finally flows out of the hose 220. In fig. 5, the fluid enters the tube 220, flows through the foot region, the waist region, and finally flows out of the tube 220.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention, therefore, all equivalent variations of the present invention are intended to be covered by the present invention.
