The plug rods 5 on both sides are inserted into the socket A301 when the bench 2 is in a working state, and the plug rod 5 is inserted into the socket B302 when the bench 2 is in a non-working state to prevent the bench 2 from swinging. A slide groove is provided on the bracket 1, a slide rod is provided in the slide groove, the slide rod is perpendicular to the movable plate 4, a spring 6 is sleeved on the slide rod, and the two ends of the spring 6 respectively abut against the lower wall of the slide groove and the lower surface of the movable plate 4. The heating assembly 10 includes an air inlet pipe 1001, a rotating drum A1002 having a channel A, a heating wire 1003 and a motor A1005. A groove 201 is provided on the bench 2, and the air inlet pipe 1001 is connected to the groove 201. The rotating drum A1002 is located in the air inlet pipe 1001 and is rotatably connected to its inner wall, and the channel A connects the groove 201 with the outside when there is someone on the bench. The electric heating wire 1003 is located in the channel A and close to the groove 201. A filter 1004 is also provided inside the opening of the end of the channel A away from the groove 201. The motor A1005 is connected to the air inlet pipe 1001 and drives the drum A1002 to rotate so as to close the air inlet of the channel A when no one is present. The heating component 10 heats the air entering the inside of the bench 2 in the working state. The exhaust component 11 includes an exhaust pipe 111, a drum B112 having a channel B, a fan 113 and a motor B114. The air inlet end of the exhaust pipe 111 is connected to the groove 201. The drum B112 is located in the exhaust pipe 111 and is rotatably connected to the inner wall thereof. The channel B connects the groove 201 and the outside world when there is someone on the bench. The fan 113 is arranged in the drum B112, and the exhaust end of the fan 113 is connected to the outside world. The motor B114 is connected to the exhaust pipe 111 and drives the drum B112 to rotate so as to close the exhaust port of the channel B when no one is there. The exhaust assembly 11, in the working state, exhausts the air that enters the seat 2 through the heating assembly 10 and blows it toward the user's legs. The backboard 13 is rotatably connected to the seat 2. A cushion 16 is provided on the backboard 13, and a plurality of flexible protrusions B17 are provided on the cushion 16. The limit assembly B includes a rotating shaft B12, a slider 14 and a driving assembly. The rotating shaft B12 is fixedly connected to the seat 2, and a spline 121 is provided on the rotating shaft B12. Two groups of sliders 14 are symmetrically arranged on the backboard 13 and slidably connected thereto, a spline hole 141 is provided on the slider 14, the rotating shaft B12 passes through the spline hole 141, and the spline 121 is engaged with the spline hole 141.The driving assembly includes a bidirectional module 15, which drives and connects two slide seats. The sliders 14 on both sides are respectively connected to the slide seats on the corresponding sides of the bidirectional module 15. The back plate 13 of the limit assembly B rotates freely in the unlocked state.

[0032] In this embodiment, the device is powered on, and a person sits on the bench 2. If the outside temperature is too low, the temperature control program is started. At this time, the motor A1005 and the motor B114 are started synchronously, and the drum A1002 and the drum B112 rotate synchronously, so that the channel A and the channel B are connected with the groove 201. Then the electric heating wire 1003 starts heating, and the fan 113 starts and draws air from the groove 201. After the outside air enters the groove 201 along the channel A, it exchanges heat with the cushion 7, so that the cushion 7 is heated up, and then the fan 113 blows the air with residual temperature to the legs of the person, so as to improve the temperature comfort of the user's legs. If the ambient temperature is high, the electric heating wire 1003 is not started at this time, and the fan 113 drives the natural air circulation. The circulating air exchanges heat with the cushion 7, reducing the local temperature of the buttocks of the human body, and the fan 113 blows the air to the legs of the person, so that the temperature of the legs and feet of the person is appropriately reduced, so as to improve the comfort of use. When the device is not used, the motor A1005 drives the drum A1002 to rotate until the opening connecting channel A to the outside world is closed, and the motor B114 drives the drum B112 to rotate until the opening connecting channel B to the outside world is closed. If the stool 2 and the backboard 13 need to be folded and stored, the movable plate 4 is pressed down to pull the plug 5 out of the socket A301. At this time, the stool can rotate freely to a vertical state, and the movable plate 4 is released. The movable plate 4 slides up under the tension of the spring 6 and inserts the plug 5 into the socket B302 to prevent the stool from swinging freely. If the inclination angle of the backboard 13 needs to be adjusted, the user presses the start switch at this time, and the two-way module 15 drives the sliders 14 on both sides to slide to disengage the spline 121. The user can freely adjust the inclination angle of the backboard 13. When the device is not needed, the backboard 13 can be flipped over to fit the stool 2.

[0033] Embodiment 2

[0035] In this embodiment, by setting up a pressure-sensitive sensor 901, a temperature sensor and a controller, when the pressure-sensitive sensor receives a pressure value of a certain size, it automatically determines that there is someone on the seat 7. At this time, the controller controls the temperature sensor to start to automatically detect the temperature of the seat cushion 7. If the temperature of the seat cushion is too high or too low, the heating program or the heat exchange and cooling program is automatically started.
