The opposite rotation of the two second hinged shafts 804 drives the rotation of the two protection plates 805 away from the ends to block the two sides of the child's body, so that the child's body is not inclined when leaning against the back plate 20, the stability of the child's sitting posture is improved, the phenomenon of the child falling to the side is prevented, and the safety of the device is improved.

[0057] Please refer to Figure 1 and Figure 2 In an embodiment, the top surface of the bottom plate 10 and the end surface of the beating plate 302 away from the mounting seat 301 are provided with soft pads 90. The soft pads 90 can improve the comfort of the child using the device.

[0058] The specific embodiment of the above-mentioned anti-vomiting type infant medicine feeding device is as follows:

[0059] First, the child sits on the bottom plate 10 with the back against the beating plate 302 and the back plate 20 to maintain a sitting position. Then, the rotation of the second rotating shaft 801 drives the rotation of the two second worms 802. The rotation of the two second worms 802 is engaged with the two second worm wheels 803 to drive the opposite rotation of the two second hinged shafts 804. The opposite rotation of the two second hinged shafts 804 drives the rotation of the two protection plates 805 away from the ends to block the two sides of the child's body, so that the child's body is not inclined when leaning against the back plate 20, the stability of the child's sitting posture is improved, the phenomenon of the child falling to the side is prevented, and the safety of the device is improved.

[0060] Then, according to the beating of the back of the child, by rotating the first screw 402 and positioning the rod 401 threaded cooperation can drive the positioning rod 401 up and down, positioning rod 401 up and down can be driven by the mounting seat 301 with the beating plate 302 up and down, thereby adjusting the height of the beating plate 302, when the beating plate 302 height adjustment stop rotating the first screw 402 and positioning the rod 401 threaded cooperation can be fixed to the mounting seat 301, thereby fixing the beating plate 302, fixed beating plate 302 height is convenient, according to the needs of the adjustment of the position of the beating of the back of the child, but also for different children to use, improve the practicability of the device.

[0061] Finally, by starting the motor 307 to make the disc 303 rotate, the disc 303 rotates to drive a plurality of groups of semi-circular conical column 304 rotation, a plurality of groups of semi-circular conical column 304 rotation can be extruded in turn the top rod 305 to make the top rod 305 along the outer surface of the semi-circular conical column 304 movement, so that the top rod 305 drive beating plate 302 away from the disc 303 movement, at the same time, the beating plate 302 away from the disc 303 movement by limiting block 3021 drive a plurality of groups of tension spring 306 stretch, when the semi-circular conical column 304 rotation cancel the extrusion of the top rod 305, the plurality of groups of tension spring 306 of the reaction force makes the beating plate 302 reverse movement reset, by a plurality of groups of semi-circular conical column 304 rotation extruded in turn the top rod 305 drive beating plate 302 reciprocating movement can be repeated on the back of the child beating, convenient for the beating of the back of the child, to help the child to expel the air in the stomach, improve the effect of preventing vomiting, improve the practicability of the device.

[0062] When it is necessary to adjust the force and frequency of patting the back of the child, the first guide block 502 is driven to drive the top rod 305 to slide along the radial direction of the rotating disc 303 by rotating the second screw rod 501 and the first guide block 502 in threaded cooperation, when the top rod 305 slides along the radial direction of the rotating disc 303 away from the center of the rotating disc 303, the top rod 305 moves along the large end of the semicircular conical column 304, at this time, the semicircular conical column 304 extrudes the top rod 305 to increase the moving length of the top rod 305 driving the patting plate 302, on the contrary, when the top rod 305 slides along the radial direction of the rotating disc 303 close to the center of the rotating disc 303, the top rod 305 moves along the small end of the semicircular conical column 304, at this time, the semicircular conical column 304 extrudes the top rod 305 to reduce the moving length of the top rod 305 driving the patting plate 302, so that the distance of the reciprocating movement of the patting plate 302 is adjusted by adjusting the position of the top rod 305, the force of the patting plate 302 patting the back of the child is adjusted by adjusting the distance of the reciprocating movement of the patting plate 302, the force of the patting plate 302 patting the back of the child is adjusted according to the needs of the child, the semicircular conical column 304 is driven to move by rotating the third screw rod 601 and the semicircular conical column 304 in threaded cooperation to make the semicircular conical column 304 be accommodated in the second guide groove 3031, at this time, the semicircular conical column 304 in the second guide groove 3031 cannot extrude the top rod 305, so that the number of the semicircular conical columns 304 extruding the top rod 305 is reduced when the rotating disc 303 rotates one circle, and the frequency of the reciprocating patting of the patting plate 302 to the back of the child is reduced, on the contrary, the semicircular conical column 304 is driven to move in the opposite direction by rotating the third screw rod 601 and the semicircular conical column 304 in threaded cooperation to make the semicircular conical column 304 extend out of the second guide groove 3031, at this time, the number of the semicircular conical columns 304 extruding the top rod 305 can be increased when the rotating disc 303 rotates one circle, and the frequency of the reciprocating patting of the patting plate 302 to the back of the child is increased, so as to adjust the frequency of the patting plate 302 patting the back of the child according to the needs of the child, and improve the practicability of the device.
