[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 4 , a pediatric nasal cleaning device is shown in the figure, comprising a barrel 1 and a flushing tube 2, wherein the barrel 1 is provided with a liquid storage chamber 11 and a waste liquid chamber 12 which are not connected to each other, wherein the liquid storage chamber 11 is used to carry the flushing liquid, and the waste liquid chamber 12 is used to carry the reflux liquid through the flushing tube 2;

[0030] The flushing pipe fitting 2 includes a first tube body 21 and a second tube body 22. The inlet of the first tube body 21 is connected to the liquid storage chamber 11. The upper end of the first tube body 21 is bent downward and fixedly connected to a connector 24. The middle part of the second tube body 22 is through-connected to the connector 24. The lower end of the second tube body 22 is through-connected to the waste liquid chamber 12. The upper end of the second tube body 22 is fixedly through-connected to a flushing head 23. A valve is arranged inside the connector 24. During flushing, the first tube body 21 is connected to the upper part of the second tube body 22. During flushing, the first tube body 21 is not connected to the second tube body 22, and the second tube body 22 is connected to the waste liquid chamber 12.

[0031] Furthermore, the valve component includes a movable valve 25 slidably installed inside the connecting head 24, a blind hole is provided on the side of the movable valve 25 facing the first tube body 21, a through hole 26 is provided on the outer surface of the movable valve 25 facing the upper part of the second tube body 22, the through hole 26 and the blind hole are connected, a connecting rod 27 is fixedly connected to the outer surface of the movable valve 25, one end of the connecting rod 27 passes through the outside of the connecting head 24 and is sleeved with a supporting spring 28, the connecting rod 27 and the connecting head 24 are slidably sealed, and the supporting spring 28 enables the movable valve 25 to be located inside the first tube body 21.

[0032] Furthermore, two groups of flushing tubes 2 are provided, and a liquid outlet mechanism 3 is provided between the two groups of flushing tubes 2 and the liquid storage chamber 11 . The liquid outlet mechanism 3 can guide the liquid medicine in the liquid storage chamber 11 into the second tube body 22 .

[0033] In this embodiment, when in use, the liquid medicine enters the first tube body 21 from the liquid storage chamber 11 under the pressure of the liquid discharge mechanism 3, and the movable valve 25 moves to the side of the second tube body 22 under the pressure of the liquid medicine. At this time, the support spring 28 undergoes elastic deformation, and the through hole 26 on the movable valve 25 is connected with the upper part of the second tube body 22. The liquid medicine is discharged into the upper part of the second tube body 22 through the through hole 26 and discharged from the flushing head 23 on the upper part of the second tube body 22. The user can flush the inside of the nasal cavity by placing the flushing head 23 inside the nasal cavity; in addition, during the flushing interval, the liquid discharge mechanism 3 no longer applies pressure to the liquid medicine, and the support spring 28 is reset, driving the movable valve 25 to move into the first tube body 21. The through hole 26 on the movable valve 25 is staggered with the second tube body 22, and the first tube body 21 and the second tube body 22 are in a disconnected state. The upper and lower parts of the second tube body 22 are connected, and the refluxed liquid medicine flows into the waste liquid chamber 12 through the second tube body 22, thereby avoiding contamination of the liquid medicine in the liquid storage chamber 11.

[0034] See also Figure 2-Figure 8 The liquid discharge mechanism 3 includes a groove 31 opened on the outer surface of the cylinder 1, a capsule 33 is fixedly connected to the inner surface of the groove 31, a pressure block 32 is slidably installed inside the groove 31, and connecting pipes 35 are connected on both sides of the capsule 33. One group of connecting pipes 35 is connected to the liquid storage chamber 11, and the other group of connecting pipes 35 is connected to the inlet of the first tube body 21, and a flow stop mechanism 5 is arranged on the connecting pipe 35. A piston plate 34 is installed in the liquid storage chamber 11, and a compression spring 37 is arranged between the piston plate 34 and the inner surface of the liquid storage chamber 11. A positioning mechanism 4 is arranged in the cylinder 1, and the positioning mechanism 4 is used to fix the piston plate 34.

[0035] Furthermore, the outer surfaces of the movable valve 25 and the piston plate 34 are both wrapped with sealing rings, the liquid storage chamber 11 and the piston plate 34 are configured as matching cylindrical structures, and the piston plate 34 can move inside the liquid storage chamber 11 .

[0036] In this embodiment, when the capsule 33 is unloaded, the compression spring 37 extends to drive the piston plate 34 to move, and the piston plate 34 squeezes the medicine liquid in the liquid storage chamber 11, so that the medicine liquid enters the capsule 33 through the connecting tube 35. When the capsule 33 is saturated, the compression spring 37 stops extending, and the capsule 33 and the liquid storage chamber 11 are in a balanced state; the user can compress the capsule 33 by pressing the pressure block 32, and the medicine liquid inside the capsule 33 can enter the first tube body 21 through the connecting tube 35, thereby realizing the flushing function; in addition, by setting the positioning mechanism 4 for use with the piston plate 34, when the pressure block 32 is pressed, the positioning mechanism 4 can fix the position of the piston plate 34, thereby preventing the medicine liquid in the capsule 33 from flowing back into the liquid storage chamber 11.

[0037] Furthermore, the positioning mechanism 4 includes a slide groove 41 opened inside the cylinder 1, the slide groove 41 is arranged along the moving direction of the pressure block 32, and a round rod 44 is fixedly connected to the surface of the pressure block 32, one end of the round rod 44 is located inside the slide groove 41 and is fixedly connected to a slider 43, a conductive block 46 is fixedly connected to the bottom of the slider 43, and a conductive sheet 42 is fixedly connected to the inner bottom surface of the slide groove 41, and a connecting spring 45 is sleeved on the surface of the round rod 44, one end of the connecting spring 45 is fixedly connected to the cylinder 1, and the other end of the connecting spring 45 is fixedly connected to the pressure block 32. In a natural state, the connecting spring 45 prevents the conductive block 46 from contacting the conductive sheet 42. An electromagnet 47 is fixedly embedded at a position outside the liquid storage chamber 11 in the cylinder 1. The conductive block 46 contacts the conductive sheet 42 to energize the electromagnet 47, and the piston plate 34 is magnetic and attracts the electromagnet 47.

[0038] In this embodiment, when the user presses the pressing block 32, the round rod 44, the slider 43 and the conductive block 46 on the pressing block 32 move accordingly, and before the pressing block 32 contacts the capsule 33, the conductive block 46 contacts the conductive sheet 42, so that the electromagnet 47 is energized to adsorb and fix the piston plate 34, thereby preventing the medicine liquid in the capsule 33 from flowing back when the pressing block 32 subsequently presses the capsule 33; in addition, when the user presses the pressing block 32, the connecting spring 45 is compressed. After the user releases the pressing block 32, the compressed connecting spring 45 can drive the pressing block 32 to reset, the conductive block 46 separates from the conductive sheet 42, the electromagnet 47 is powered off and no longer attracts the piston plate 34, and the compression spring 37 can drive the piston plate 34 to move again to push the medicine liquid into the capsule 33.

[0039] See also Figure 8The flow-stopping mechanism 5 includes a movable pressing plate 51 and a fixed pressing plate 52. The movable pressing plate 51 is set as a U-shaped structure.

A flow-stopping spring 53 is fixedly connected between the closed end of the movable pressing plate 51 and the inner surface of the groove 31. In the natural state, the flow-stopping spring 53 causes the movable pressing plate 51 to press the connecting pipe 35 tightly.

[0040] In this embodiment, by providing a flow-stop mechanism 5, when the user presses the pressing block 32, the closed end of the movable pressing plate 51 on the pressing block 32 gradually moves away from the fixed pressing plate 52, thereby no longer compressing the connecting tube 35 between the first tube body 21 and the capsule body 33, and the medicine liquid in the capsule body 33 can be transported to the inside of the first tube body 21; when the user releases the pressing block 32, the movable pressing plate 51 is reset under the action of the flow-stop spring 53, and re-compresses the connecting tube 35 to facilitate fluid replenishment to the inside of the capsule body 33.
