[0018] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but this does not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0019] Example

[0020] A respiratory tract sprayer described in this embodiment, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, it includes a spray bottle 1, and two symmetrically distributed hinged plates 11 are provided at the nozzle 12 of the spray bottle 1. A fixed tube 2 is provided between the two hinged plates 11, and the fixed tube 2 is hinged to the two hinged plates 11 through two hinge blocks 17. A telescopic hose 3 connected to the nozzle 12 is installed in the fixed tube 2, and a nozzle 4 is provided at the water outlet end of the telescopic hose 3. A plurality of spray holes 5 are opened at the movable end of the nozzle 4. Two symmetrically distributed fixed plates 6 are provided on the outer side wall of the movable end of the fixed tube 2. A connecting plate 8 with an "L"-shaped structure is hinged between the two fixed plates 6. A fixed plate 8 is fixed on the connecting plate 8. A protective cover 7 is provided for sealing the movable end of the fixed tube 2, and a movable component for pushing the nozzle 4 to move is provided on the fixed tube 2; the spray bottle 1 is a press-type spray bottle in the prior art, and the spray bottle 1 includes a bottle body: used to contain liquid medicine, generally made of materials such as plastic or glass, which can withstand internal pressure and ensure the sealing of the medicine; nozzle: the nozzle contains structures such as an air valve, a nozzle and a piston. When the nozzle is pressed, these structures will interact with each other to spray the medicine in the form of mist; the piston and spring: located inside the nozzle. When the nozzle is pressed, the piston will be compressed and the spring will be compressed at the same time. When the spray head is released, the spring will rebound and push the piston to return to its original shape, and in this process, the gas pressure inside the spray head will change; compressed air reservoir: used to store compressed air. When the spray head is pressed, the compressed air will be released into the bottle body, increasing the pressure inside the bottle, thereby pushing the medicine to be sprayed out; sealing gasket: located at the connection between the spray head and the bottle body, ensuring the sealing of the spray bottle and preventing medicine leakage; medicine outlet: a small hole between the spray head and the bottle body or inside the spray head, used as a channel for medicine spraying; when in use, the spray head is pressed, the piston inside the spray head is compressed, and at the same time, the gas pressure inside the spray head is changed. If there is a compressed air reservoir inside the spray bottle, the compressed air will be released into the bottle body, further increasing the pressure inside the bottle. This increased pressure will push the liquid medicine to be sprayed out through the nozzle inside the spray head, forming a mist. When the spray head is released, the spring will rebound, pushing the piston to return to its original shape, and at the same time, changing the gas pressure inside the spray head, preparing for the next press; the spray bottle 1 in this embodiment is a prior art, and the internal structure and principle of the spray bottle 1 have not been improved;

[0021] Two hinged plates 11 are provided at the nozzle of the spray bottle 1 nozzle, and the hinged plates 11 are glued to the spray head. A fixed tube 2 is provided between the two hinged plates 11, and two hinge blocks 17 are welded or glued on the fixed tube 2. The two hinge blocks 17 are hinged on the corresponding hinge plates 11 respectively, and the fixed tube 2 is hinged between the two hinged plates 11 through the hinge blocks 17. One end of the telescopic hose 3 is welded or glued to the nozzle 12 of the spray bottle 1 and is connected to it. The other end of the telescopic hose 3 is welded or glued with a nozzle 4. The movable end of the nozzle 4 is provided with a number of spray holes 5 for spraying medicine. The telescopic hose 3 and the nozzle 4 are installed in the fixed tube 2. The fixed tube 2 protects the telescopic hose 3 and the nozzle 4 to prevent the nozzle 4 from contacting with external pollutants and causing infection, and also to prevent the nozzle 4 from being damaged and becoming unusable; rotating The fixed tube 2 rotates around the hinge of the hinge block 17, driving the nozzle 4 in the fixed tube 2 to rotate, causing the angle of the nozzle 4 to change. The angle of the nozzle 4 can be adjusted according to the patient's spraying needs, so that the patient's respiratory tract can be sprayed better. When the fixed tube 2 drives the nozzle 4 to rotate, the telescopic hose 3, due to its telescopic and flexible characteristics, expands or bends along with the rotation of the nozzle 4. The degree of bending will not block the flow of the liquid medicine in the telescopic hose 3. The liquid medicine can flow into the telescopic hose 3 through the nozzle 12, and then into the nozzle 4 to be sprayed from the multiple spray holes 5. When the nozzle 4 moves in the fixed tube 2, it drives the telescopic hose 3 to expand and contract. When the nozzle 4 extends out of the movable end of the fixed tube 2, the telescopic hose 3 is stretched accordingly. When the nozzle 4 is retracted into the fixed tube 2, the telescopic hose 3 is compressed accordingly, which does not affect the spraying of the medicine.

[0022] The outer side wall of the movable end of the fixed tube 2 is provided with two fixed plates 6, and a connecting plate 8 is hinged between the two fixed plates 6 through a damping shaft. The connecting plate 8 has an inherent protective cover 7. The protective cover 7 is rotated to rotate around the hinge driven by the connecting plate 8. The protective cover 7 blocks the movable end of the fixed tube 2 and protects the nozzle 4 to prevent it from being infected. The fixed tube 2 is provided with a moving component for pushing or retracting the nozzle 4 from the fixed tube 2. The moving component includes a through groove opened on the fixed tube 2, and a fixed block 10 fixed to the nozzle 4 is provided at the through groove. A slide 9 located at the top of the fixed tube 2 is provided on the top of the fixed block 10; a through groove communicating with the inside and outside is opened on the side wall of the fixed tube 2, and a fixed Block 10, the bottom of the fixed block 10 is welded or glued to the outer wall of the nozzle 4, and the top of the fixed block 10 is welded or glued with a slide 9. When in use, the slide 9 is pushed to move on the top of the fixed tube 2, thereby driving the fixed block 10 to move in the through groove, so that the nozzle 4 is extended from the fixed tube 2 or retracted into the fixed tube 2. When the nozzle 4 is extended from the fixed tube 2, the medicine outlet end of the nozzle 4 is extended into the patient's mouth to spray the patient's respiratory tract, and the spraying effect is better; the slide 9 is an arc-shaped plate, the bottom of the slide 9 is fitted with the top of the fixed tube 2, the curvature of the slide 9 arc plate is consistent with the curvature of the outer wall of the fixed tube 2, the width of the through groove is smaller than the width of the slide 9, and the slide 9 slides more smoothly and stably on the top of the fixed tube 2;

[0023] A limit strip 13 is fixed to the inner wall of the through slot. The limit strip 13 and the fixing block 10 are pressed against each other. The limit strip 13 is adhered to the inner wall of the through slot. The limit strip 13 is made of a soft and elastic rubber material. When the limit strip 13 and the fixing block 10 are pressed against each other, this structure is further compressed, increasing the contact area and thus increasing the friction. The limit strip 13 can deform when squeezed or twisted. Although this deformation is small, it is sufficient to increase the friction between the fixing block 10 and the limit strip 13 when it moves in the through slot, thereby confining the fixing block 10 in the through slot, fixing the position of the nozzle 4 when it is extended or retracted, and spraying medicine into the patient's respiratory tract.

[0024] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the movable end of the fixed tube 2 is provided with a magnetic ring 14, and the magnetic ring 14 is adhered to the movable end of the fixed tube 2. The protective cover 7 is made of iron. When the protective cover 7 is rotated to the movable end of the fixed tube 2, the protective cover 7 contacts the magnetic ring 14, and the two attract each other, thereby fixing the protective cover 7 to protect the nozzle 4 inside the fixed tube 2. When the nozzle 4 needs to be removed from the fixed tube 2, the protective cover 7 is rotated around the hinge to expose the movable end of the fixed tube 2, so that the nozzle 4 is removed from the fixed tube 2 to spray medicine into the patient's respiratory tract; and the protective cover 7 is kept in place. A sealing plug is provided on the inner wall of the protective cover 7. The sealing plug is adhered to the inner wall of the protective cover 7. The diameter of the sealing plug is smaller than that of the protective cover 7 and is consistent with the diameter of the inner wall of the fixed tube 2. When the protective cover 7 blocks the movable end of the fixed tube 2, the inner wall of the protective cover 7 contacts the magnetic ring 14, and the sealing plug on the inner wall of the protective cover 7 is inserted into the movable end of the fixed tube 2 to seal the movable end of the fixed tube 2, so that the interior of the fixed tube 2 is sealed, thereby better protecting the nozzle 4 in the fixed tube 2 and preventing infection.

[0025] like Figure 4 As shown, a slide groove 16 is provided on the inner wall of the fixed tube 2, and a slider 15 is provided in the slide groove 16 to slide with the slide groove 16 and fixed to the nozzle 4. Two slide grooves 16 are provided on the inner wall of the fixed tube 2, and sliders 15 are provided in both slide grooves 16. The sliders 15 are welded or adhered to the outer wall of the nozzle 4. When the nozzle 4 moves in the fixed tube 2, the fixed tube 2 slides more steadily and smoothly due to the sliding cooperation between the slide groove 16 and the slider 15, and the fixed tube 2 is prevented from completely detaching from the fixed tube 2. The length of the fixed tube 2 extending outside the fixed tube 2 is limited, making it more stable.

[0026] During actual use, the protective cover 7 is rotated to rotate around the hinge point, and the protective cover 7 exposes the movable end of the fixed tube 2. The nozzle 4 is moved out of the fixed tube 2 by using the moving component, and the nozzle 4 extends out of the fixed tube 2. The nozzle 4 is inserted into the patient's mouth, and the nozzle head of the spray bottle 1 is pressed to make the liquid in the spray bottle 1 spray from the nozzle 12 to the telescopic hose 3, and then enter the nozzle 4 and spray out from several spray holes 5 to apply medicine to the patient's respiratory tract. When the angle of the nozzle 4 needs to be adjusted, the fixed tube 2 is rotated to rotate around the hinge point, thereby driving the spray angle of the nozzle 4 to change, the spray range is larger, and the spray effect on the patient's respiratory tract is better.
