In the invention, the working principle is as follows: firstly, the infant is laid on the foam sponge cushion 11, and since the magnetorheological fluid 12 has no magnetic field, the suspension phase particles are suspended in the mother solution and are randomly distributed to present a linear viscous Newtonian fluid. After the external magnetic field is applied, the surface of the particles is polarized to form magnetic dipoles, and the magnetic dipoles are connected into a chain-shaped or cluster-shaped structure along the direction of the external magnetic field and have a certain shear-resistant yield stress. The shear yield stress between adjacent particles in the same polarizing chain increases with the strength of the applied magnetic field. When the magnetic field is increased to a certain degree, the interaction of the magnetic dipoles is enhanced, and the magnetorheological fluid has a solid-like characteristic, namely, the magnetorheological fluid has a low-viscosity Newtonian fluid characteristic under the condition of zero magnetic field; and under the action of a strong magnetic field, the solid material has the characteristics of high viscosity and low fluidity. When the device is not powered on, the magnetorheological fluid 12 below the foam sponge cushion 11 is in a liquid state, the foam sponge cushion 11 on which an infant lies can be correspondingly sunken according to the back curve of the infant, so that different infants can be adapted to different lying postures, the foam sponge cushion is deformed and memorizes corresponding shapes, the infant can lie on a bed more comfortably, the pressure of the infant body on the spine which is not completely developed is relieved, the development of the infant skeleton is facilitated, the sponge ball 81 of the massage device 7 is adjusted to the corresponding comfortable massage position of the infant abdomen, the control switch 3 is turned on at the moment, the internal power supply is powered on, the conductive coil 9 flows current, the coil is wound outside one conductor according to the eddy current effect, and the coil is switched on with alternating current, so that the coil generates an alternating magnetic field. Because the conductor in the middle of the coil is a closed circuit which can be equivalent to a circle in the circumferential direction, the magnetic flux in the closed circuit is changed continuously, induced electromotive force and induced current are generated in the circumferential direction of the conductor, and the direction of the current is rotated in the circumferential direction of the conductor, like a vortex of one turn, therefore, the phenomenon that electromagnetic induction occurs inside the whole conductor to generate induced current is called as eddy current phenomenon, and the generated magnetic field can make the magnetorheological fluid 12 instantly present the characteristics of solid, thereby memorizing and fixing the curve of the back of the infant, simultaneously fixing the position of the massage device 7, simultaneously heating the conductor post 8 by the eddy current phenomenon, due to the existence of the heat insulation plate 10, a part of heat can be transferred to the magnetorheological fluid 12, and the heated magnetorheological fluid 12 can heat the foam sponge cushion 11, so that an infant lying on the foam sponge cushion can not catch a cold;

meanwhile, the air in the cavity where the conductor column 8 is located is heated to expand, the expanded hot air passes through the air guide hose 4, so that the pressure of the air in the cavity where the spring 72 is located on the piston 73 is increased, when the pressure on the piston 73 is greater than the elastic force of the spring 72 on the piston 73, the piston 73 can move rightwards, so that the first rocker 75 is driven to rotate, the second rocker 77 is driven to rotate through the first rotating shaft 76, the rotating rod 79 rotates through the second rotating shaft 80, when the pressure is gradually increased, when the piston 73 moves rightwards to the maximum position, redundant gas can be discharged from the gas outlet 74, the pressure is relieved, at the moment, the pressure is reduced instantaneously, the piston 73 moves leftwards under the action of the elastic force of the spring 72, negative pressure is formed in the cavity due to the discharged gas, new air can be injected from the gas one-way valve 13 under the action of the negative pressure, thereby realizing the reciprocating motion of the piston 72, the rotating rod 79 rotates all the time, and the two sponge balls 81 are driven to rotate, thereby achieving the massage effect on the infant.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
