The effect of the elastic film in the present invention is: under the pulling of pendulum block, elastic film is stretched, and then will form a medicine holding space between elastic film and the upper cavity surface of mechanism chamber, and when elastic film is stretched During the process, the medicine holding space generates negative pressure, and under the action of atmospheric pressure, the medicine in the medicine holding tank can flow into the medicine holding space from the small hole, and finally the medicine in the medicine holding tank will not spill out but flow into the medicine holding tank in space.

When the user feeds medicine to the child, when the child does not swing the spoon housing, the spring film is in close contact with the surface of the small hole in the mechanism cavity.

In the process of the user feeding medicine to the child, when the child swings the spoon housing upward or downward, take the downward swing of the spoon housing as an example: when the spoon housing swings downward around the axis of the pin, the first The C-shaped spring is compressed, the second gear swings down with the spoon housing and the second gear rotates around the outer surface of the first gear, and at the same time the second gear rotates counterclockwise around its own axis, then the second gear passes through The third gear, the fourth gear, the fifth gear, the sixth gear, and the seventh gear drive the eighth gear to rotate counterclockwise; the eighth gear drives the input gear to rotate clockwise, the first transmission pinion moves to the direction of the second spring, and the 1. The small transmission gear disengages from the meshing with the input gear, and the large transmission gear meshes with the input gear; the input gear drives the output gear to rotate clockwise through the transmission large gear, and the output gear drives the ninth gear to rotate counterclockwise through the meshing of bevel teeth; The two-way overrunning clutch ring drives the first shaft to rotate counterclockwise; the first shaft drives the pendulum to swing downward through the pendulum, and the second C-shaped spring is compressed; under the pull of the pendulum, the elastic film is stretched to form a space for holding medicine , in the process of stretching the elastic film, negative pressure is generated in the medicine-holding space, and under the action of atmospheric pressure, the medicine in the medicine-holding tank can flow into the medicine-holding space from the small hole, and finally the medicine in the medicine-holding tank will not Instead, it spills out and flows into the medicine holding space.

After the spoon housing swings downward, under the return action of the first C-shaped spring, the spoon housing swings upward to the original position; during the upward swing of the spoon housing, the second gear follows the spoon housing and swings upward And the second gear rotates around the outer circular surface of the first gear, while the second gear rotates clockwise around its own axis, then the second gear passes through the third gear, the fourth gear, the fifth gear, the sixth gear, the The seventh gear drives the eighth gear to rotate clockwise; the eighth gear drives the input gear to rotate counterclockwise, the large transmission gear moves towards the direction of the first spring, the transmission large gear disengages from the meshing with the input gear, and the first transmission pinion gear is respectively connected to the input gear and The second transmission pinion meshes; the input gear drives the output gear to rotate clockwise through the first transmission pinion and the second transmission pinion, and the output gear drives the ninth gear to rotate counterclockwise through the bevel meshing; the ninth gear passes through the two-way overrunning clutch ring Drive the first shaft to rotate counterclockwise; the first shaft continues to drive the pendulum to swing downward through the pendulum; when the pendulum swings to the maximum, the second C-shaped spring is compressed to the maximum, and at this time The medicine is completely inhaled into the medicine holding space. When the spoon housing swings to the original position, under the reset action of the second C-shaped spring, the elastic film can squeeze the medicine in the medicine holding space back into the medicine holding groove; Resetting does not affect the rotation of the ninth gear; in summary, the medicine in the medicine holding tank will not spill out at last, which is beneficial for feeding medicine to children.

Compared with the traditional spoon technology, the medicine contained in the medicine holding tank in the spoon shell of the present invention will not spill out during the swinging process of the spoon shell, but will be released into the medicine holding tank through the elastic film by the effect of pressure difference. The medicine in the medicine holding space is squeezed into the medicine holding space; when the spoon shell automatically returns to the unswinged position, the medicine in the medicine holding space is squeezed into the medicine holding groove by the elastic film; the design of the invention is simple, and it has relatively Good practical effect.

In the medicine-holding space, a negative pressure is generated in the medicine-holding space, and under the action of atmospheric pressure, the medicine in the medicine-holding tank 40 can flow into the medicine-holding space through the small hole 24, so that the medicine in the medicine-holding tank 40 will not spill out but flow into the medicine-holding space at last. In the medicine storage space.

After the downward swing of the spoon housing 1 is completed, under the reset action of the first C-shaped spring 5, the spoon housing 1 swings upward to the original position; during the upward swing of the spoon housing 1, the second gear 6 follows The spoon housing 1 swings upwards and the second gear 6 rotates around the outer circumference of the first gear 4, while the second gear 6 rotates clockwise around its own axis, then the second gear 6 passes through the third gear 7, the fourth The gear 8, the fifth gear 9, the sixth gear 10, and the seventh gear 11 drive the eighth gear 12 to rotate clockwise; the eighth gear 12 drives the input gear 28 to rotate counterclockwise, and transmit the large gear 29 to move in the direction of the first spring 36, The large transmission gear 29 disengages from the engagement with the input gear 28, and the first transmission pinion 31 meshes with the input gear 28 and the second transmission pinion 32 respectively; the input gear 28 is driven by the first transmission pinion 31 and the second transmission pinion 32 The output gear 30 rotates clockwise, and the output gear 30 drives the ninth gear 14 to rotate counterclockwise through the engagement of the bevel teeth 27; the ninth gear 14 drives the first shaft 26 to rotate counterclockwise through the bidirectional overrunning clutch ring 39; the first shaft 26 passes through the swing rod 16 continues to drive the pendulum block 17 to swing downward; when the pendulum block 17 swings downward to the maximum, the second C-shaped spring 15 is compressed to the maximum, and at this time the medicine in the medicine holding tank 40 is completely sucked into the medicine holding space middle. When the spoon housing 1 swung to the original position, under the reset action of the second C-shaped spring 15, the elastic film 18 could squeeze the medicine in the medicine-containing space back into the medicine-containing groove 40; effect, the reset of the elastic film 18 does not affect the rotation of the ninth gear 14; in summary, the medicine in the medicine holding tank 40 will not spill out at last, which is beneficial for feeding medicine to children.

To sum up, the beneficial effects of the present invention are: the medicine contained in the medicine holding groove 40 in the spoon housing 1 will not spill out during the swinging process of the spoon housing 1, but will be released by using the pressure difference through the elastic film 18. The function is to squeeze the medicine in the medicine holding tank 40 into the medicine holding space; when the spoon housing 1 automatically returns to the unswinged position, the medicine in the medicine holding space is squeezed into the medicine holding groove by the elastic film 18 40; the present invention is simple in design and has good practical effect.
