The one-way valve in the air inlet pipe 19 only allows the outside air to enter the air guide groove 9, and the one-way valve in the air guide pipe 20 only allows the air in the air guide groove 9 to enter the air bag 6.

It is worth mentioning that the air bag 6 plays a role of storing gas, and in the process of accelerating and decelerating the automobile, the outside air can be temporarily stored in the air bag 6 through the sliding of the piston 11, so that the gas can continuously enter the gas collecting groove 4. Thus, even in the process of stopping the automobile, gas still enters the gas collecting groove 4, and then the air can be blown continuously to the back of the child.

The side wall of the seat 1 is provided with a cylindrical groove 15, and a sound production device capable of producing certain melody is arranged in the cylindrical groove 15. The sounding device comprises a rotating wheel 16 which is rotatably connected to the inner wall of a cylindrical groove 15, a plurality of sounding pipes 17 are fixedly connected to the side wall of the rotating wheel 16, the cylindrical groove 15 is communicated with an air guide groove 9 through a bottom air pipe 23, and a tone hole 18 is formed in the side wall of each sounding pipe 17. It should be noted that the number of the sounding pipes 17 is seven, and the seven sounding pipes 17 are annularly arranged in the order of the distance between the tone holes 18 and the air inlets of the sounding pipes 17. Different tone holes 18 are arranged on the side wall of the sounding pipes 17, so that the air can generate different tones of sound when flowing through the air inlets of the sounding pipes 17; seven sound-emitting tubes 17 are annularly arranged in the order of distance from the tone holes 18 to the air inlets of the sound-emitting tubes 17, so that a melody is generated when the rotary wheel 16 rotates. In addition, in practical application, the positions of the tone holes 18 can be flexibly arranged according to the tones of common cradle music, so that a soft cradle music is generated by the seven sound-generating tubes 17 in the continuous rotating process, and the hypnotic effect can be achieved for the children on the seat.

A driving mechanism capable of driving the rotation wheel 16 to rotate is installed in the cylindrical groove 15. The driving mechanism comprises a hollow rotating column 24 which is rotatably connected in the cylindrical groove 15, the screw 12 is connected with the inner thread of the hollow rotating column 24, the hollow rotating column 24 is rotatably connected at the central position on the inner wall of the cylindrical groove 15, and the hollow rotating column 24 and the screw 12 are made of the same material. One end of the screw 12 far away from the hollow rotary column 24 is fixedly connected to the side wall of the piston 11, and the rotating wheel 16 is connected with the hollow rotary column 24 through a one-way bearing 25.

The side wall of the seat 1 is provided with an annular groove 13, a coil 14 is arranged in the annular groove 13, the piston 11 is located at the central position of the coil 14, a heating wire 21 and a temperature control switch 22 are arranged in the gas collecting groove 4, the side wall of the seat 1 is provided with a plurality of LED colored lamps 26, and the coil 14, the heating wire 21, the plurality of LED colored lamps 26 and the temperature control switch 22 are electrically connected.

In the invention, when the automobile accelerates or decelerates, the piston 11 will slide back and forth in the air guide groove 9 under the action of inertia. When the automobile is accelerated, the piston 11 slides towards the direction far away from the air inlet pipe 19, and the piston 11 can suck the outside air into the air guide groove 9 through the air inlet pipe 19; when the automobile runs at a constant speed or a deceleration speed after being accelerated, the piston 11 slides towards the direction close to the air inlet pipe 19, and then the piston 11 can push the air in the air guide groove 9 into the air bag 6 through the air guide pipe 20. Along with gaseous continuous the entering, the volume of gasbag 6 is constantly expanded, and after the pressure in the gasbag 6 reached a definite value, pressure valve 8 can be opened, and then the gas in the gasbag 6 can be discharged into gas collecting tank 4 from blast pipe 7, and the gas in the gas collecting tank 4 can blow children's back through gas pocket 3 and porous back of the body pad 2 on. This makes the laminating department air current circulation nature of children's back and seat 1 better, and then accelerates the evaporation of children's back sweat, prevents that the allergic phenomenon of skin from appearing in children's back.

It should be noted that a certain current is generated in the coil 14 during the reciprocating sliding of the piston 11. When the temperature in the vehicle is high, the temperature control switch 22 is in an off state; when the temperature in the vehicle is low, the temperature control switch 22 is closed, the electric current can enable the heating wire 21 to generate heat, and then the heating wire 21 can heat the gas in the gas collecting tank 4; meanwhile, the LED colored lamp 26 can be electrified to emit light, so that the attention of children can be attracted. Therefore, under the condition of low temperature in the vehicle, the gas in the gas collecting groove 4 is heated by the electric heating wire 21, and then hot air can be blown to the back of the child, so that the back of the child is prevented from catching a cold, and the comfort of the child is improved; the luminous LED coloured lamp 26 attracts the attention of the child and prevents the safety belt from loosening due to crying or movement of the child on the seat 1.

Meanwhile, the piston 11 drives the screw 12 to move in the reciprocating process, the screw 12 drives the hollow rotary column 24 to rotate, the rotary wheel 16 can continuously rotate under the action of the one-way bearing 25, and the sound emitting tubes 17 can rotate along with the rotary wheel 16. Meanwhile, the piston 11 can continuously exhaust gas into the cylindrical groove 15 through the bottom air pipe 23 in the reciprocating motion process, the gas outlet end of the bottom air pipe 23 is opposite to the gas inlet of the sounding pipe 17, in the continuous rotation process of the sounding pipe 17, the gas inlet of the sounding pipe 17 can sequentially pass through the gas outlet end of the bottom air pipe 23, and the positions of the tone holes 18 in each sounding pipe 17 are different, so that the lengths of air columns in the sounding pipes 17 are different, different sounds can be generated when the sounding pipes 17 pass through the bottom air pipe 23, and a plurality of sounding pipes 17 can form a regular melody in the continuous rotation process. The melody can attract the attention of the child and can prevent the child from crying or shaking on the seat to cause the looseness of the safety belt.
