Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1 to 5 This is a nasal spray device for nasal inflammation disclosed in an embodiment of this utility model. Please refer to [link / reference]. Figure 1 and Figure 2 The system includes a bottle body 1, with an externally threaded mounting port 11 at the upper end. A suction tube 2 is inserted into the mounting port 11, and a fixing tube 21 is fixedly installed on the outside of the suction tube 2. The fixing tube 21 is threadedly connected to the mounting port 11. Please refer to [link / reference]. Figure 1 and Figure 3 The suction tube 2 is slidably mounted with the spray tube 3. A piston ring 31 is fixedly mounted at the bottom of the spray tube 3. A one-way ball 4 is placed at the bottom of both the suction tube 2 and the spray tube 3. The lower ends of the suction tube 2 and the spray tube 3 are tapered. Please refer to [link / reference]. Figure 1 and Figure 4 The upper end of the spray pipe 3 is fixedly installed with an atomizing nozzle 5. A return spring 201 is installed inside the suction pipe 2. The upper end of the return spring 201 abuts against the spray pipe 3. An adjusting nut 6 is threadedly connected to the outside of the spray pipe 3. A pressing tube 7 is sleeved on the outside of the spray pipe 3. The pressing tube 7 is slidably connected to the suction pipe 2. The upper end of the inner side of the pressing tube 7 abuts against the atomizing nozzle 5.

[0031] Specifically, a suction tube 2 and a spray tube 3 are installed on the bottle body 1. When the suction tube 2 is pressed, the medicine in the spray tube 3 is pressurized, causing the one-way ball 4 of the suction tube 2 to block the suction tube 2 downwards, forcing the medicine to push upwards and open the one-way ball 4 of the spray tube 3 before being sprayed out. Under the push of the return spring 201, the spray tube 3 returns to its original position, and the one-way ball 4 of the spray tube 3 is sucked downwards to block the spray tube 3, forming a cavity inside the suction tube 2. This causes the one-way ball 4 of the suction tube 2 to move upwards, thereby drawing the medicine in the bottle body 1 into the suction tube 2. When it is necessary to change the spray volume, the pressing tube 7 is removed, and the adjusting nut 6 is rotated to change the stroke of the spray tube 3, thereby changing the spray volume.

[0032] In this way, the spray volume can be changed by adjusting the adjusting nut 6, making it convenient for people with different needs to use.

[0033] In some feasible configurations, both the suction tube 2 and the spray tube 3 are cylindrical tubes with an inner diameter larger than that of the matching one-way ball 4. A tapered end is provided at the bottom to facilitate a seal with the one-way ball 4. An annular component is glued to the upper end of the suction tube 2, serving both to seal the upper end after installation and to provide radial support for the spray tube 3. The upper end of the return spring 201 abuts against the piston ring 31, and the lower end abuts against the bottom of the suction tube 2. The suction tube 2 has threads on its outer side, and an adjusting nut 6 is threaded onto these threads. The adjusting nut 6 has a circumferential array of protrusions on its outer side for easy rotation. The atomizing nozzle 5 is tapered, reducing the nozzle diameter to atomize the medication. The atomizing nozzle 5 is glued to the upper end of the spray tube 3. The lower end of the suction tube 2 is connected to a cylindrical tube, allowing the suction tube 2 to extend to the bottom of the bottle body 1.

[0034] The upper part of the pressing tube 7 is conical to facilitate insertion into the nasal cavity. The pressing tube 7 rests against the atomizing nozzle 5 to create downward pressure on the spray tube 3. The lower part of the pressing tube 7 is a cylindrical tube that fits the outer diameter of the fixing tube 21, allowing the pressing tube 7 to slide along the fixing tube 21 when pressed. An elliptical plate is provided on the outer side of the lower part of the pressing tube 7 to facilitate the application of force by the fingers when pressing.

[0035] As one specific embodiment of the nasal spray device provided in this application, please refer to Figure 1 and Figure 4 A pressure spring 32 is installed inside the spray pipe 3, and the lower end of the pressure spring 32 abuts against the one-way ball 4 inside the spray pipe 3.

[0036] Overall, by setting the pressure spring 32, during the resetting process of the spray pipe 3, the pressure spring 32 provides downward pressure to make the one-way ball 4 reset in time to block the spray pipe 3, reducing the possibility of backflow of the agent in the spray pipe 3, and at the same time facilitating the formation of a cavity in the suction pipe 2 to draw in the agent, thereby improving the accuracy of quantitative spraying.

[0037] In some feasible configurations, the upper end of the pressure spring 32 abuts against the atomizing nozzle 5, and the lower end abuts against the one-way ball 4.

[0038] As another specific embodiment of the nasal spray device provided in the application, please refer to Figure 1 and Figure 4 A sealing cap 71 is fitted on the outside of the pressing tube 7, and a sealing cone 72 is fixedly installed on the inner side of the top of the sealing cap 71. After installation, the sealing cone 72 abuts against the atomizing nozzle 5.

[0039] Depending on the specific usage scenario, after use, the sealing cap 71 is installed to protect the pressing tube 7, and the sealing cone 72 abuts against the atomizing nozzle 5 to reduce the possibility of contamination of the agent remaining in the spray tube 3.

[0040] As another specific embodiment of the nasal spray device provided in the application, magnetic rings are installed at the contact positions of the pressing tube 7 and the atomizing nozzle 5.

[0041] It should be understood that the magnetic connection formed by the magnetic ring facilitates the disassembly of the pressing tube 7, thereby facilitating timely disassembly and cleaning after use.

[0042] As another specific embodiment of the nasal spray device provided in the application, please refer to Figure 1 and Figure 2 A positioning half-ring 23 is attached to the outside of the suction tube 2, and the two ends of the positioning half-ring 23 abut against the bottle body 1 and the pressing tube 7 respectively.

[0043] It should be understood that by setting the positioning semi-ring 23 between the bottle body 1 and the pressing tube 7, the pressing tube 7 is prevented from being pressed when not in use, which could cause the medicine to spray out.

[0044] In some feasible methods, the positioning half-ring 23 is an elastic arc ring with a central angle greater than 180 degrees. To facilitate the disassembly of the positioning half-ring 23, a rectangular piece is fixedly installed on the positioning half-ring 23.

[0045] As one specific embodiment of the nasal spray device provided in this application, please refer to Figure 1 and Figure 5 At least one one-way air inlet 22 is provided at the upper end of the fixed pipe 21.

[0046] It should be understood that by setting up a one-way air inlet 22, when the medicine is being drawn from the bottle body 1, the air pressure inside the bottle body 1 is balanced by air intake through the one-way air inlet 22.

[0047] Furthermore, the one-way air inlet 22 includes a through hole opened in the fixed pipe 21, a perforated plate 221 is provided at the upper end of the through hole, a rubber sheet 222 is provided at the bottom of the through hole, and a connecting rod 223 is fixedly connected between the perforated plate 221 and the rubber sheet 222.

[0048] It should be understood that by setting the rubber sheet 222 and the perforated plate 221, when pressed, the gas pushes the rubber sheet 222 to deform and allow air to enter. When the pressing tube 7 is reset, the rubber sheet 222 is suctioned upward to close the through hole.

[0049] In some feasible configurations, the one-way air inlet 22 is located between the mounting port 11 and the suction tube 2.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
