DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Embodiment 1: Refer to Figures 1-4, A sprayer, including a handle 1. The handle 1 enables medical staff to hold the sprayer, facilitating its use. Inside the handle 1, there is a storage cavity 2 for storing the amount of liquid medicine required for a single spray. On one side of the outer part of the handle 1, a micro pump 8 is fixedly installed. The end of the micro pump 8 close to the handle 1 is connected to a hose 5. The end of the hose 5 is fixedly installed with a hollow ball 4. The micro pump 9 can suck out the liquid medicine stored in the storage cavity 2 through the hose 5 and the hollow ball 4. The end of the micro pump 8 far from the handle 1 is fixedly installed with a gooseneck tube 9. The end of the gooseneck tube 9 far from the micro pump 8 is fixedly installed with a nozzle 10. The micro pump 8 sends the sucked liquid medicine to the nozzle 10 through the gooseneck tube 9, and the liquid medicine can be sprayed through the nozzle 10. The shape of the gooseneck tube 9 can be adjusted according to needs, which can facilitate the insertion of the nozzle 10 into different parts of the human ear, nose and throat, directly and accurately send the nozzle 10 to the required treatment site, and can spray medicine targeted, thus improving the treatment effect.

[0020] At the inner side of the end of the handle 1, there is a medicine supply mechanism connected by threads. The medicine supply mechanism is used to provide liquid medicine for the sprayer. The medicine supply mechanism includes a medicine storage box 11, which can store liquid medicine and provide the required liquid medicine for the sprayer. One end of the outer side of the medicine storage box 11 is threadedly connected to the inner side of the end of the handle 1. The connection between the medicine storage box 11 and the handle 1 is convenient for disassembly and assembly. After removing the connection between the medicine storage box 11 and the handle 1, it is convenient to clean the inside of the storage cavity 2. Inside the end of the medicine storage box 11, a one-way valve 15 is fixedly installed, which can send the liquid medicine in the medicine storage box 11 into the storage cavity 2. On the outer side of the other end of the medicine storage box 11, a box cover 12 is sleeved by threads. The connection between the box cover 12 and the medicine storage box 11 is convenient for removal, which is convenient for cleaning the inside of the medicine storage box 11. Inside the box cover 12, a screw rod 13 is arranged by threads. The end of the screw rod 13 extending to the inner side of the medicine storage box 11 is rotatably connected to a piston 14. The length direction of the screw rod 13 is perpendicular to the surface of the piston 14. By rotating the screw rod 13, the height of the piston 14 can be adjusted. When the piston 14 moves, it can squeeze the liquid medicine downward, and the squeezed liquid medicine will enter the storage cavity 2 through the one-way valve 15.

[0021] When filling the liquid medicine inside the medicine storage box 11, first take out the box cover 12, the screw rod 13 and the piston 14 from inside the medicine storage box 11, pour the liquid medicine into the medicine storage box 11, then fit the box cover 12 with the end of the medicine storage box 11. Rotating the screw rod 13 can drive the piston 14 to move, so that the piston 14 moves to the liquid level of the liquid medicine. Observation windows 16 are fixedly installed on both the side wall of the medicine storage box 11 and the storage cavity 2. The observation window 16 is composed of a transparent plate structure. The outer surface of the observation window 16 is evenly engraved with scales. The observation window 16 can observe the specific liquid level height of the liquid medicine inside the medicine storage box 11 and the storage cavity 2, and the amount of the liquid medicine can be accurately read through the scales. When driving the piston 14 to move by rotating the screw rod 13, the piston 14 squeezes the liquid medicine in the medicine storage box 11 into the storage cavity 2 through the one-way valve 15. By observing the change of the liquid level of the liquid medicine at all times, after sending a specified amount of liquid medicine into the storage cavity 2, stop rotating the screw rod 13 to complete a medicine delivery operation. When the liquid medicine in the storage cavity 2 is used up, the screw rod 13 can be rotated again to drive the piston 14 to move to squeeze the liquid medicine into the storage cavity 2, and multiple quantitative medicine deliveries can be realized.

[0022] A bottom cavity 3 is opened at the bottom of the storage cavity 2. The diameter of the bottom cavity 3 is smaller than that of the storage cavity 2. As shown in the attached drawing, the liquid medicine at the bottom of the storage cavity 2 can enter the bottom cavity 3. The diameter of the bottom cavity 3 is small, and the hollow ball 4 is placed in the bottom cavity 3. Compared with the flat bottom of the storage cavity 2, by setting the bottom cavity 3, the solution at the bottom of the storage cavity 2 can be prevented from tilting, because this sprayer cannot always maintain an upright state during use and will tilt to varying degrees. If the bottom of the storage cavity 2 is in a flat state, then the tilted solution and the hollow ball 4 may move away from each other, and the hollow ball 4 cannot contact the solution. Therefore, the micro pump 8 cannot suck out the remaining solution in the storage cavity 2, resulting in the actual amount of liquid medicine sprayed this time being less than the required amount of liquid medicine. By setting the bottom cavity 3, the space for accommodating the liquid medicine at the bottom of the storage cavity 2 is reduced, so that the remaining liquid medicine can be stored in the bottom cavity 3. Even if this sprayer tilts to varying degrees, the liquid medicine will not run out of the bottom cavity 3, enabling the hollow ball 4 to always contact the liquid medicine and being able to suck out the liquid medicine completely, and the actual amount of sprayed medicine can be accurately controlled.

[0023] A limiting frame 6 is fixedly installed inside the bottom cavity 3. The limiting frame 6 is sleeved outside the hose 5. The hollow ball 4 is located below the limiting frame 6. The limiting frame 6 plays a role in restricting the hollow ball 4 to prevent the hollow ball 4 from separating from the bottom cavity 3. Since the hollow ball 4 is connected by the hose 5 and the hose 5 can be deformed, if preparing a liquid medicine that needs to be shaken, medical staff may shake this sprayer, then the hollow ball 4 may separate from the bottom cavity 3 and run into the storage cavity 2, and the liquid medicine cannot be accurately quantitatively sprayed. The limiting frame 6 can play a role in restricting the hollow ball 4 and can prevent the situation where the hollow ball 4 runs around.

[0024] A heating strip 7 is fixedly installed on the surface of the slope that transitions between the upper part of the bottom cavity 3 and the bottom of the storage cavity 2. A battery pack for power supply is connected beside the heating strip 7. By turning on the power inside the heating strip 7, the heating strip 7 can be used to heat the liquid medicine in the storage cavity 2, enabling the temperature inside the liquid medicine to be raised to a suitable temperature for the human body and preventing discomfort when spraying the medicine on relevant parts of the human body.

[0025] Working principle: During the use of this sprayer, the liquid medicine is loaded into the medicine storage box 11. Rotating the screw rod 13 drives the piston 14 to move. The movement of the piston 14 squeezes the liquid medicine into the storage cavity 2 through the one-way valve 15. The amount of the squeezed liquid medicine is controlled according to the observation window 16, ensuring that the amount of the sprayed liquid medicine is within the controlled range each time. After a certain amount of liquid medicine is squeezed into the storage cavity 2, the medical staff holds the handle 1 and adjusts the bending state of the gooseneck tube 9, extending the nozzle 10 to the part to be treated. The shape of the gooseneck tube 9 can be adjusted according to different treatment parts for spraying medicine on different treatment parts. Then the nozzle 10 is opened, and at the same time, the micro pump 8 sucks out the liquid medicine through the hose 5 and the hollow ball 4. The sucked liquid medicine is sprayed out through the nozzle 10. During the spraying process, the hollow ball 4 is always located in the bottom cavity 3 under the restriction of the restriction frame 6, and there is always liquid medicine in the bottom cavity 3. Even if the sprayer is tilted, the liquid medicine will not run out of the bottom cavity 3 until the hollow ball 4 completely sucks out the remaining liquid medicine in the bottom cavity 3, that is, the spraying is completed, and there will be no phenomenon that the liquid medicine is not completely sprayed, further ensuring that a fixed amount of liquid medicine can be sprayed each time.
