[0036] In the embodiment, the intermediate pipe 3 is provided with an anti-overflow structure 5 at the end close to the spray head 4, the anti-overflow structure 5 comprises a first fixed ring 51 and a second fixed ring 54, the second fixed ring 54 is threadedly connected with the cylindrical surface of the intermediate pipe 3, the first fixed ring 51 is sleeved on the cylindrical surface of the intermediate pipe 3, the first fixed ring 51 can be rotated to adjust the position of the first fixed ring 51, a plurality of groups of first connecting rods 55 and second connecting rods 56 are arranged between the first fixed ring 51 and the second fixed ring 54, one end of the second connecting rod 56 is connected with the middle of the first connecting rod 55, the first connecting rod 55, the second connecting rod 56 and the intermediate pipe 3 are arranged in an umbrella shape, and a protective cover 53 is attached between each first connecting rod 55, the protective cover 53 can be covered on the spray head 4 when needed, the position around the ear, nose and throat can be shielded when the medicine is sprayed, so as to reduce the overflow of some atomized liquid from the ear, nose and throat position when the spray head 4 is directed at the ear, nose and throat position, and the normal spraying of the medicine is not affected when the protective cover 53 is gathered by moving the first fixed ring 51.

[0037] In the embodiment, the first connecting rod 55 is movably connected with the first fixed ring 51, the second connecting rod 56 is movably connected with the first connecting rod 55 and the second fixed ring 54 at both ends, the first fixed ring 51 and the second fixed ring 54 are away from each other, the protective cover 53 is gathered, the first fixed ring 51 and the second fixed ring 54 are close to each other, the protective cover 53 is unfolded, and the protective cover 53 can be gathered and unfolded like an umbrella by moving the first fixed ring 51.

[0038] In the embodiment, the intermediate pipe 3 is provided with a fixed ring 52 outside, the diameter of the fixed ring 52 is greater than the diameter of the first fixed ring 51, and the fixed ring 52 is sleeved with the protective cover 53, the protective cover 53 is sleeved by the fixed ring 52 to avoid the unfolding of the protective cover 53.

[0039] It needs to be explained that when the ear-nose-throat treatment is carried out, the medicine is often given through the medicine sprayer. When in use, the middle pipe 3 is rotationally connected with the pressing pump 2, so that the pressing pump 2 is rotated around the middle pipe 3 to a suitable angle, so that the nozzle 4 at the end of the middle pipe 3 can be directed at the wound position of the ear-nose-throat, the medicine sprayer bottle body 1 is held and the pressing pump 2 is pressed to make the pressing pump 2 work, so that the pressing pump 2 and the extraction pipe 6 at the bottom end of the pump body fixing shell 9 extract the liquid in the medicine sprayer bottle body 1, so that the liquid can be sprayed out at the nozzle 4. Since some medicines need to be shaken every time they are used, sometimes forgetting to spray can cause the liquid in the medicine sprayer bottle body 1 to be mixed unevenly, or there are suspended solids in the medicine sprayer bottle body 1. At this time, the mixing structure 7 and the check structure 8 can be matched. When the pressing pump 2 is pressed, the middle downward pressing fixed rod 72 of the pressing pump 2 will move along the fixed hole 71 in the pump body fixing shell 9. At this time, the gas in the fixed hole 71 will be compressed so that the gas enters the inside of the first fixed hemisphere 81 and the second fixed hemisphere 82 along the connecting pipe 73. Then the gas pushes the floating ball 83 to make the floating ball 83 roll down along the inside of the floating groove 85. When the floating ball 83 rolls to the bottom end of the floating groove 85, air can be discharged from the air vent groove 86. When the gas enters the inside of the large medicine sprayer bottle body 1, bubbles can be generated. At this time, the liquid in the medicine sprayer bottle body 1 is mixed under the action of the bubbles, so that the liquid in the medicine sprayer bottle body 1 is more evenly mixed. When the pressing pump 2 is released, the pump body reset structure can make the pressing pump 2 reset. The pressing pump 2 drives the fixed rod 72 to move upward along the inside of the fixed hole 71. Under the action of the extension spring 84, the floating ball 83 is lifted, the air vent part of the first fixed hemisphere 81 is blocked, and the liquid cannot enter the inside of the fixed hole 71 from the connecting pipe 73. At the same time, due to the negative pressure in the fixed hole 71, the turnover sheet 77 is rotated, so that the gas in the medicine sprayer bottle body 1 enters the inside of the fixed hole 71, ensuring that the pressing pump 2 can normally rise. Since the air vent hole 74 is connected with the inside of the medicine sprayer bottle body 1, there may be a small amount of liquid in the fixed rod 72. When the fixed rod 72 descends, the liquid and air are discharged into the check structure 8 through the connecting pipe 73, and the turnover sheet 77 is pressed against the top end of the air vent hole 74 when it is pressed down, so that the turnover sheet 77 will not turn over, and the gas will not be discharged from the air vent hole 74. In this process, when the pressing pump 2 extracts the liquid, the liquid in the medicine sprayer bottle body 1 can be mixed, so that the liquid in the medicine sprayer bottle body 1 is mixed, avoiding forgetting to shake the medicine sprayer bottle body 1 every time it is used, causing the medicine sprayer bottle body 1 to contain precipitates or suspended solids. When spraying ear-nose-throat medicines, the liquid often exists in the form of mist. When spraying in the narrow space of the nose or mouth, it is easy to cause the mist sprayed in the mouth, nose, etc. to overflow or the misted liquid to adhere to other body parts, causing waste.At this time, the anti-overflow structure 5 on the intermediate tube 3 is unfolded, specifically, the first fixed ring 51 is close to the second fixed ring 54 on the intermediate tube 3, so that each group of first connecting rods 55 and second connecting rods 56 are unfolded in an umbrella shape, so that the protective cover 53 covers the nozzle 4, at this time, the nozzle 4 is opposite the oral cavity, nasal cavity and the like, some atomized liquid can be reduced from the ear, nose and throat position by the protective cover 53, when not in use, the first fixed ring 51 can be moved to make the protective cover 53 gather, so as not to affect normal spraying of the medicament.
