Description

Technical Field

[0001] This utility model relates to the field of nasal spray technology, and in particular to a nasal spray that is easy to adjust. Background Technology

[0002] With the fast pace of modern life and increasing environmental pollution, more and more people are experiencing nasal problems such as nasal congestion and allergic rhinitis. As the body's respiratory tract, the nasal cavity is directly exposed to the outside air and is easily susceptible to bacteria, viruses, and air pollutants. The frequency of nasal problems increases significantly, especially during seasonal transitions. Therefore, nasal care and treatment have become an important part of people's daily lives.

[0003] Existing nasal sprays cannot adjust the spray direction according to the user's actual situation, resulting in the spray not being accurately sprayed to different areas of the nasal cavity, causing waste of medication or liquid. At the same time, they cannot adjust the spray intensity according to the user's nasal condition, resulting in sprays that are too strong or too weak, causing discomfort to the user. Utility Model Content

[0004] The purpose of this invention is to provide a nasal spray that is easy to adjust, allowing the spray angle to be adjusted so that the spray can be more accurately sprayed to different areas of the nasal cavity, and different spray volumes can be selected according to needs.

[0005] To achieve the above objectives, a conveniently adjustable nasal spray is provided, comprising a bottle body, a cover plate for sealing the top of the bottle body being threadedly connected to the top of the bottle body, a support block being fixedly connected to the upper outer surface of the cover plate, a pressing mechanism being provided on the upper right side of the support block, the pressing mechanism comprising a mounting sleeve fixedly connected to the upper outer surface of the support block, a pressing chamber being provided inside the mounting sleeve, and a piston being provided inside the pressing chamber;

[0006] Two fixing blocks are fixedly connected to the upper left side of the support block. A limiting block is set between the two fixing blocks. A nozzle is set at the other end of the limiting block. The rotation of the limiting block drives the rotation of the nozzle, thereby adjusting the spray angle so that the spray can be accurately sprayed to different areas of the nasal cavity.

[0007] According to the aforementioned easily adjustable nasal spray, a push barrel is slidably connected to the upper outer surface of the mounting sleeve, and a spring is fixedly connected to the lower outer surface of the push barrel. The lower end of the spring is fixedly connected to the upper outer surface of the pressing chamber. The spring enables the push barrel to reset after pressing.

[0008] According to the aforementioned easily adjustable nasal spray, a connecting rod is fixedly connected to the lower outer surface of the push barrel, the lower end of the connecting rod is fixedly connected to the upper outer surface of the piston, and the piston is slidably connected to the inner surface of the pressing chamber.

[0009] According to the aforementioned easily adjustable nasal spray, a knob is fixedly connected to the front outer surface of the fixing block, and a rotating rod is fixedly connected to the rear outer surface of the knob. The rotating rod passes through the front outer surface of the fixing block and is fixedly connected to the rotating block. The rotating block is fixedly connected to the outer surface of the limiting block. By setting the knob, rotating rod, and limiting block, the limiting block is driven to adjust the angle, thereby driving the nozzle to adjust the spray direction and ensuring that the spray can adapt to different usage angles.

[0010] According to the aforementioned easily adjustable nasal spray, a water delivery pipe is installed inside the bottle body, and a one-way valve is fixedly connected to the upper end of the water delivery pipe. The one-way valve is located on the lower inner surface of the pressing chamber. When the piston is pressed down, the one-way valve closes, and when the piston rises, the one-way valve opens.

[0011] According to the aforementioned easily adjustable nasal spray, a second one-way valve is provided on the inner surface of the left side of the pressing chamber. A water outlet pipe is fixedly connected to the left end of the second one-way valve. The water outlet pipe passes through the inner surface of the limiting block and is fixedly connected to the right end of the nozzle. The water outlet pipe is a flexible hose and does not affect the rotation of the limiting block and the nozzle. When the piston is pressed down, the second one-way valve opens; when the piston rises, the second one-way valve closes.

[0012] According to the aforementioned adjustable nasal spray, the outer surface of the bottle is provided with a viewing window, and the outer surface of the viewing window is evenly distributed with scale lines to help users better manage the use of the spray.

[0013] According to the aforementioned adjustable nasal spray, a plurality of limiting grooves are provided through the outer surface of the push barrel, and a limiting plate is inserted into the inside of the limiting groove. The user can adjust the spray intensity according to the nasal cavity condition to prevent discomfort caused by excessive or insufficient spray.

[0014] This utility model has the following beneficial effects:

[0015] 1. Compared with the prior art, this easy-to-adjust nasal sprayer adjusts the distance of the descent of the push barrel by placing the limiting plate in different limiting grooves. This allows the spray intensity to be adjusted according to the user's nasal condition, preventing discomfort caused by excessive or insufficient spray. Pressing the push barrel moves the connecting rod and piston downwards, and the spraying of medicine is achieved through the setting of one-way valve one and one-way valve two.

[0016] 2. Compared with the prior art, this easy-to-adjust nasal sprayer uses a knob, rotating rod and rotating block to drive the limit block to rotate, thereby driving the nozzle to rotate. The water outlet pipe is a flexible hose, which does not affect the rotation of the limit block and the nozzle, thus ensuring that the spray can adapt to different usage angles.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] Reference Figure 1-4This utility model provides an easily adjustable nasal spray, which includes a bottle body 1. A water supply pipe 11 is installed inside the bottle body 1. A one-way valve 12 is fixedly connected to the upper end of the water supply pipe 11. The one-way valve 12 is located on the lower inner surface of the pressing chamber 42. When the piston 45 is pressed down, the one-way valve 12 is closed, and when the piston 45 is raised, the one-way valve 12 is opened. A viewing window 15 is provided on the outer surface of the bottle body 1. Scale lines 16 are evenly distributed on the outer surface of the viewing window 15 to facilitate the user's observation of the usage. A cover plate 2 for sealing the top of the bottle body 1 is threadedly connected to the top of the bottle body 1. A support block 3 is fixedly connected to the upper outer surface of the cover plate 2. A pressing mechanism 4 is provided on the upper right side of the support block 3.

[0028] The pressing mechanism 4 includes a mounting sleeve 41 fixedly connected to the upper outer surface of the support block 3. A push barrel 43 is slidably connected to the upper outer surface of the mounting sleeve 41. A spring 46 is fixedly connected to the lower outer surface of the push barrel 43. The lower end of the spring 46 is fixedly connected to the upper outer surface of the pressing chamber 42. When the pressing push barrel 43 is released, the elastic action of the spring 46 drives the connecting rod 44 and the piston 45 to return to their original position. At this time, the pressure in the pressing chamber 42 decreases, and the medicine flows into the pressing chamber 42 from the water pipe 11, thus allowing the medicine to enter. Several limiting grooves 432 are opened through the outer surface of the push barrel 43. Limiting plates 431 are inserted into the inside of the limiting grooves 432. A connecting rod 44 is fixedly connected to the lower outer surface of the push barrel 43. The lower end of the connecting rod 44 is fixedly connected to the upper outer surface of the piston 45. 45 is slidably connected to the inner surface of the pressing chamber 42. A one-way valve 14 is provided on the left inner surface of the pressing chamber 42. When the piston 45 is pressed down, the one-way valve 14 opens and when the piston 45 rises, the one-way valve 14 closes. The left end of the one-way valve 14 is fixedly connected to the water outlet pipe 13. The water outlet pipe 13 is a flexible hose that passes through the inner surface of the limiting block 9 and is fixedly connected to the right end of the nozzle 10. By pressing the pushing barrel 43, the connecting rod 44 and the piston 45 inside the pressing chamber 42 move downward. Then, through the action of the one-way valve 12 and the one-way valve 14, the medicine is sprayed out. By inserting the limiting plate 431 into different limiting grooves 432, the pressing distance of the pushing barrel 43 can be adjusted, thereby adjusting the intensity of the medicine spray according to the actual situation of the user and preventing discomfort caused by excessive or insufficient spray.

[0029] Two fixing blocks 5 are fixedly connected to the upper left side of the support block 3. A knob 6 is fixedly connected to the front outer surface of the fixing block 5. A rotating rod 7 is fixedly connected to the rear outer surface of the knob 6. The rotating rod 7 passes through the front outer surface of the fixing block 5 and is fixedly connected to a rotating block 8. The rotating block 8 is fixedly connected to the outer surface of the limiting block 9. A nozzle 10 is provided at the other end of the limiting block 9. By setting the fixing block 5, knob 6, rotating rod 7 and rotating block 8, the limiting block 9 and nozzle 10 can be adjusted, so as to flexibly adjust according to different parts of the nasal cavity, so that the spray can be sprayed more accurately to different areas of the nasal cavity, avoiding waste of medicine or liquid.

[0030] Working principle: When using this easy-to-adjust nasal spray, turning the knob 6 drives the rotating rod 7 to rotate, which in turn drives the rotating block 8 and the limiting block 9 to rotate, thereby adjusting the angle of the nozzle 10. The water outlet pipe 13 is a flexible hose, which does not affect the angle adjustment of the limiting block 9 and the nozzle 10, thus allowing the spray to be accurately sprayed to different areas of the nasal cavity and avoiding waste of medication.

[0031] Depending on the user's nasal cavity condition, the limiting plate 431 is placed in different limiting grooves 432 to control the descent distance of the push barrel 43, thereby adjusting the spray intensity and preventing discomfort caused by excessive or insufficient spray. Pressing the push barrel 43 then moves the connecting rod 44 and piston 45 downwards. Through the one-way valve 12 and one-way valve 14, the medication is sprayed. The embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model.
