The cylinder body 1 is made of transparent material and marked with scales. The push rod 2 is a long rod-shaped structure. One end of the push rod 2 moves in and out of the cylinder body 1. The other end of the push rod 2 is provided with a base 21 for convenient hand gripping and control of the push rod 2 moving in and out. The length of the push rod 2 that can move in the cylinder body 1 is the same as the length of the cylinder body 1. Figure 3 In the figure, the base 21 of the push rod 2 is set in a truncated cone shape, and its diameter is larger than the caliber of the cylinder 1. The setting of the base 21 makes it convenient to grasp the push rod 2 to adjust the volume of the cylinder 1, and can prevent the push rod 2 from completely entering the cylinder 1.
[0035] like Figure 6 As shown, one end of the cylinder 1 is an insertion end 11 into which the push rod 2 is inserted, and the other end of the cylinder 1 is a medicine inlet end 12 through which the powder enters the cylinder 1. The outer wall of the push rod 2 is fitted with the inner wall of the cylinder 1, and the distance between the end of the push rod 2 in the cylinder 1 and the medicine inlet end 12 determines the capacity of the cylinder 1 for containing the powder.
[0036] After the push rod 2 is pulled to the position of the required dosage, the powder is poured into the cylinder 1 from the medicine inlet end 12 until it is full, which is the required dosage of the powder. After the measurement is completed, the push rod 2 is pushed to push the powder out from the medicine inlet end 12 and the powder can be taken by the child.
[0037] In order to facilitate the powder to enter the cylinder 1, the present embodiment further includes a funnel 3, the funnel 3 includes an open end 32 and a narrow end 311, and the narrow end 311 is arranged at the neck 31 of the funnel 3. The medicine feeding end 12 of the cylinder 1 can be inserted into the narrow end 311 of the funnel 3, and the powder enters the cylinder 1 from the open end 32 of the funnel 3.
[0038] like Figure 4 and Figure 5As shown, the inner wall of the neck 31 is provided with an annular protrusion 33. When the barrel 1 is inserted into the neck 31, the medicine feeding end 12 of the barrel 1 and the side wall of the protrusion 33 are close to and in contact with each other. The side of the protrusion 33 that can contact the medicine feeding end 12 of the barrel 1 has an annular groove 35 inside the protrusion 33, as shown in FIG. Figure 6 As shown in FIG. 3 , the groove 35 is connected to the inner wall of the neck 31 of the funnel 3 .
[0039] A movable plug 4 is provided inside the funnel 3 for isolating the narrow end 311 and the open end 32 from being connected to each other. The movable plug 4 is arranged on the side of the protrusion 33 away from the drug feeding end 12 of the cylinder 1. A through hole 34 is provided on the protrusion 33, and the direction of the through hole 34 is the same as the length direction of the cylinder 1. A movable rod 41 is provided on the side of the piston that contacts the protrusion 33. The other end of the movable rod 41 passes through the through hole 34 and is located on the other side of the protrusion 33. When the cylinder 1 is inserted into the narrow end 311, the drug feeding end 12 of the cylinder 1 pushes the movable rod 41, driving the movable plug 4 away from the protrusion 33, connecting the narrow end 311 and the open end 32. In order to facilitate the resetting of the movable plug 4, a spring 43 is provided in the slot 35 to facilitate the resetting of the synchronization ring 42.
[0040] In order to prevent the movable plug 4 from getting stuck due to different forces on the movable rods 41, the through holes 34 and the movable rods 41 are each provided with a plurality of holes, and the through holes 34 and the movable rods 41 are arranged correspondingly. The end of the movable rod 41 close to the drug feeding end 12 is connected with a synchronization ring 42, and the drug feeding end 12 of the cylinder 1 acts on the synchronization ring 42.
[0041] like Figure 6 As shown, the barrel 1 is inserted into the neck 31 of the funnel 3, acting on the synchronization ring 42, overcoming the force of the spring 43 upward, and opening the movable plug 4 upward, so that the open end 32 and the narrow end 311 of the funnel 3 are connected. At this time, pour the powder into the funnel 3, and the powder enters the barrel 1 through the side of the movable plug 4. When the powder has reached or is about to reach the scale required by the user, the barrel 1 of the neck 31 of the funnel 3 is directly pulled out, and the synchronization ring 42 and the movable plug 4 return to their original positions under the elastic force of the spring 43. The movable plug 4 isolates the open end 32 of the funnel 3 from each other, so that the remaining powder in the funnel 3 will not flow out. Figure 7 shown.
[0042] In this embodiment, three movable rods 41 are provided, and correspondingly, three through holes 34 are also provided on the protrusion 33 .
[0043] In order to prevent the synchronizer ring 42 from escaping from the neck 31 of the funnel 3 , a stopper 36 is provided on the inner wall where the narrow end 311 is located. The diameter of the synchronizer ring 42 is larger than the aperture of the stopper 36 , and the aperture of the stopper 36 is the same as the outer diameter of the cylinder 1 .
