Description

Technical Field

[0001] This utility model relates to the field of sprayer technology, specifically a sprayer for respiratory medicine. Background Technology

[0002] In respiratory medicine treatment, sprayers are a common drug delivery device widely used to provide necessary medication to patients. Sprayers are usually equipped with a rotating nozzle, which allows patients to adjust the direction and angle of the spray as needed, thereby improving the targeting and comfort of the treatment. They can spray the drug in atomized form, making it easy to apply the medication to the patient's mouth, thereby achieving the purpose of treatment.

[0003] However, in actual use, the rotary nozzle is often easy to rotate freely when not subjected to external force, making it difficult to store. Furthermore, although some sprayers are equipped with protective covers, these covers are often poorly constructed and have unreliable fixing methods, making them easy to lose during use or transport. Once the protective cover is lost, the rotary nozzle will be directly exposed to the external environment, increasing the risk of contamination and making it unsuitable for patients. Utility Model Content

[0004] The purpose of this invention is to provide a respiratory medicine sprayer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a respiratory medicine sprayer, comprising a spray bottle, a pressing nozzle movably mounted on the top of the spray bottle, an adjusting spray pipe fixedly mounted on one side of the pressing nozzle, an annular groove formed near the top of the spray bottle, a limiting ring slidably connected within the annular groove, a transmission ring fixedly connected to the outer wall of the limiting ring, a squeezing groove formed on one side of the transmission ring, a guide groove formed near the bottom of the transmission ring on the spray bottle, a first protective cover fixedly connected to the side of the spray bottle near the guide groove, a guide block slidably connected within the guide groove, a second protective cover fixedly connected to the side of the guide block away from the guide groove, a transmission plate fixedly connected to one side of the top of the second protective cover, a transmission shaft fixedly connected to the top of one side of the transmission plate, and the transmission shaft slidably connected to the squeezing groove.

[0006] Preferably, an adjusting plate is fixedly connected to the side of the transmission ring away from the extrusion groove, and the corners of the adjusting plate are chamfered.

[0007] Preferably, the adjusting nozzle is a rotatable nozzle, and a rotation gap is left between the adjusting nozzle and the bottom ends of the first protective cover and the second protective cover.

[0008] Preferably, the extrusion groove is a curved groove, and the extrusion groove is opened at an angle.

[0009] Preferably, the guide block has a T-shaped structure design, and the guide groove is opened corresponding to the guide block.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by limiting the adjustment nozzle with the first protective cover, the accuracy of the adjustment nozzle's retraction and reset can be improved. At the same time, the second protective cover can be adjusted arbitrarily, so that the first and second protective covers can effectively protect the adjustment nozzle without affecting its rotation, and are reliably fixed, avoiding the loss of the protective cover. The structure is simple and easy to use. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1-5This utility model provides a technical solution: a respiratory medicine sprayer, including a spray bottle 1, a pressing nozzle 2 movably mounted on the top of the spray bottle 1, an adjusting nozzle 3 fixedly mounted on one side of the pressing nozzle 2, an annular groove 4 near the top of the spray bottle 1, a limiting ring 5 slidably connected in the annular groove 4, a transmission ring 6 fixedly connected to the outer wall of the limiting ring 5, a squeezing groove 7 on one side of the transmission ring 6, a guide groove 8 near the bottom of the transmission ring 6, a first protective cover 9 fixedly connected to the side of the spray bottle 1 near the guide groove 8, a guide block 10 slidably connected in the guide groove 8, a second protective cover 11 fixedly connected to the side of the guide block 10 away from the guide groove 8, a transmission plate 12 fixedly connected to one side of the top of the second protective cover 11, a transmission shaft 13 fixedly connected to the top of one side of the transmission plate 12, and the transmission shaft 13 slidably connected to the squeezing groove 7.

[0019] An adjusting plate 14 is fixedly connected to the side of the transmission ring 6 away from the extrusion groove 7. The corners of the adjusting plate 14 are chamfered to facilitate the rotation of the transmission ring 6 and prevent the corners of the adjusting plate 14 from scratching fingers. The adjusting nozzle 3 is a rotatable nozzle. There is a rotation gap between the adjusting nozzle 3 and the bottom of the first protective cover 9 and the second protective cover 11 to facilitate the rotation of the adjusting nozzle 3 and prevent motion interference between the adjusting nozzle 3 and the first protective cover 9 and the second protective cover 11. The extrusion groove 7 is a curved groove and is opened at an angle to facilitate the extrusion transmission of the transmission shaft 13. The guide block 10 has a T-shaped structure design. The guide groove 8 is opened corresponding to the guide block 10 to facilitate the guide of the guide block 10 by the guide groove 8.

[0020] Specifically, when using this invention, the sprayer is operated by rotating the transmission ring 6 via the adjusting plate 14. The transmission ring 6 then rotates along the annular groove 4 via the limiting ring 5. The rotating transmission ring 6 then squeezes the transmission shaft 13 via the squeezing groove 7. Since the guide block 10 is fixedly connected to the second protective cover 11, and the second protective cover 11 is fixedly connected to the transmission shaft 13 via the transmission plate 12, the squeezed transmission shaft 13 drives the second protective cover 11 to move via the transmission plate 12. The second protective cover 11 then moves downward along the guide groove 8 via the guide block 10. At this time, the first protective cover 9 and the second protective cover 11 are separated. The adjusting nozzle 3 can be rotated arbitrarily in a direction away from the first protective cover 9. After use, the adjusting nozzle 3 and the second protective cover 11 can be reset.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
