Description

Technical Field

[0001] This utility model relates to the field of nasal spray technology, specifically to a nasal spray device. Background Technology

[0002] In the medical and personal care fields, nasal spray devices are commonly used treatment and care tools, and their performance and user experience are crucial. However, existing nasal spray devices have some significant design shortcomings. First, the connection between the nozzle and the bottle is often inflexible and difficult to disassemble, causing inconvenience for users when cleaning or replacing the nozzle. Even in designs that allow nozzle disassembly, unstable connections make the nozzle prone to detaching during use, affecting spray effectiveness, potentially wasting liquid, and even injuring the user. Second, the lack of dustproof measures makes the nozzle susceptible to external contamination, reducing hygiene and safety. Furthermore, the nozzle's press design is often flawed, requiring effort to operate and producing an unsatisfactory mist, resulting in a poor user experience.

[0003] For example, Chinese patent publication number CN118948611A, entitled "A Nasal Irrigation Device for Radiotherapy Nursing Care of Nasopharyngeal Carcinoma Patients," includes a liquid-holding bottle with a connecting tube at one end for transferring liquid within the bottle. A nozzle for spraying the liquid is installed at the other end of the connecting tube. A single-circulation mechanism that changes the internal air pressure when pressed is also provided on the outside of the bottle. A pressure control mechanism is also provided inside the bottle to control the pressure on the bottle body. A directional adjustment mechanism is also provided inside the connecting tube to adjust the spray direction of the nozzle. The single-circulation mechanism includes an air bladder fixedly connected to one side of the outer wall of the liquid-holding bottle, with multiple one-way valves equidistantly connected to the outer wall of the air bladder. The disadvantage is that the connection between the nozzle and the bottle body is often inflexible and difficult to disassemble, causing inconvenience for users when cleaning or replacing the nozzle. Utility Model Content

[0004] To address the shortcomings of existing nasal spray devices where the nozzle is inconvenient to assemble and disassemble, the purpose of this invention is to provide a nasal spray device that optimizes the connection between the nozzle and the bottle body, ensuring that the nozzle is both easy to assemble and disassemble and not prone to falling off.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a nasal spray device, comprising a bottle body and a connecting tube for transmitting liquid inside the bottle body, a nozzle is installed at one end of the connecting tube, one side of the nozzle is hinged to the bottle body, and the other side of the nozzle is provided with an elastic protrusion. One end of the bottle body is provided with a raised edge, and the surface of the raised edge away from the nozzle is provided with a groove for engaging the elastic protrusion.

[0006] In this technical solution, one side of the nozzle is hinged to the bottle body, allowing the nozzle to rotate flexibly and facilitating disassembly and assembly. Meanwhile, the other side of the nozzle has a flexible protrusion that engages with a groove on the raised edge of one end of the bottle body. This ingenious structural design ensures that the nozzle is firmly fixed to the bottle body after assembly, preventing it from easily falling off, thereby improving the reliability and ease of use of the device.

[0007] This invention is further configured such that the spray head includes a nozzle and a pressing part, the pressing part being disposed on the side near the elastic protrusion. This arrangement not only makes operation more convenient—allowing the user to trigger the spray with a simple press—but also, combined with the elastic protrusion, further enhances the stability and ease of use of the connection between the spray head and the bottle body, improving the overall user experience.

[0008] This invention is further configured such that: the nozzle has a third protrusion at one end near the bottle body, the third protrusion having a through hole; and the inner surface of the bottle body has a second protrusion that mates with the through hole, the second protrusion passing through the through hole to hinge the nozzle to the bottle body. The nozzle has a third protrusion at one end near the bottle body, and the third protrusion has a through hole; while the inner surface of the bottle body cleverly features a second protrusion that mates with the through hole. The second protrusion passing through the through hole achieves a stable hinge connection between the nozzle and the bottle body. This design not only allows the nozzle to rotate flexibly to adapt to different usage angles, but also ensures the firmness of the connection between the nozzle and the bottle body, improving the overall stability and durability of the device.

[0009] This invention is further configured such that both the second and third protrusions are elastic structures. The connection between the nozzle and the bottle body employs an elastic structure design, giving the nozzle a certain degree of flexibility and adaptability during hinged connections. This allows for easier adjustment of the usage angle and provides a buffering effect when subjected to external impacts, enhancing the durability and reliability of the device. Simultaneously, the elastic structure design facilitates the disassembly and assembly of the nozzle, improving ease of use.

[0010] This invention is further configured such that a dust cover is provided at the nozzle, and the dust cover is snapped into one end of the bottle body. The dust cover at the nozzle, and its snap-fit ​​connection to one end of the bottle body, effectively protects the nozzle from dust and contaminants, maintaining its cleanliness and hygiene, thus ensuring the hygiene and safety of the spray. Simultaneously, the snap-fit ​​connection makes the dust cover easy to install and remove, facilitating daily maintenance and cleaning, and enhancing the overall user experience and practicality of the device.

[0011] This invention is further configured such that one end of the bottle body has a stepped surface, and the port of the dust cover mates with the stepped surface to secure the dust cover to one end of the bottle body. The stepped surface at one end of the nasal spray device's bottle body is a clever design that allows the port of the dust cover to perfectly mate with it, not only achieving a secure hold of the dust cover at one end of the bottle body but also making it easier to open. When needed, the user can easily remove the dust cover from the stepped surface by simply lifting the port, making the operation simple and quick, greatly improving convenience and user experience.

[0012] This invention is further characterized by a flexible and transparent dust cover. The flexible and transparent design of the dust cover not only allows it to fit snugly against the stepped surface of the bottle, effectively preventing the intrusion of dust and contaminants and maintaining the cleanliness of the nozzle, but also allows users to clearly see the status of the nozzle, facilitating inspection and maintenance at any time. The flexible structure also makes opening and closing the dust cover more flexible and easy, further improving the ease of use and user experience of the device.

[0013] This invention is further configured such that the nozzle has a channel that communicates with a connecting pipe. The nasal spray device's nozzle has an internal channel that is tightly connected to the connecting pipe. This design ensures that the liquid in the bottle flows smoothly through the connecting pipe into the nozzle, and is then sprayed out in the form of a mist through the nozzle. The connection between the channel and the connecting pipe not only ensures the continuity and stability of the spray, but also improves the device's efficiency, allowing users to easily and quickly obtain the desired spray effect.

[0014] This invention is further configured such that the upper surface of the pressing part is provided with a friction structure to increase friction. The upper surface of the pressing part of the nasal spray device is designed with a friction structure to increase friction. This design makes the contact between the user's finger and the pressing part more stable and less prone to slippage when pressing the nozzle, thereby improving the accuracy and stability of pressing. The presence of the friction structure enhances the user experience, making operation easier and smoother, and ensuring good pressing effect even when hands are wet or sweaty.

[0015] The present invention is further configured such that the nozzle is horn-shaped or conical.

[0016] The advantages of this utility model are: (1) the connection method between the nozzle and the bottle body is optimized to ensure that the nozzle is easy to disassemble and not easy to fall off; (2) one side of the nozzle is connected to the bottle body by a hinge, so that the nozzle can rotate flexibly and is easy to disassemble and assemble; at the same time, the other side of the nozzle is provided with an elastic protrusion, which cooperates with the groove provided on the protrusion on one end of the bottle body to ensure that the nozzle can be firmly fixed to the bottle body after assembly and is not easy to fall off, thereby improving the reliability and convenience of the device.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] Example 1:

[0026] Reference Figures 1 to 5A nasal spray device includes a bottle body 1 and a connecting tube 2 for transmitting liquid inside the bottle body 1. A nozzle 3 is installed at one end of the connecting tube 2. One side of the nozzle 3 is hinged to the bottle body 1. The other side of the nozzle 3 is provided with an elastic protrusion 31. One end of the bottle body 1 is provided with a raised edge 11. The surface of the raised edge 11 away from the nozzle 3 is provided with a groove 12 for cooperating with the elastic protrusion 31.

[0027] In this embodiment, one side of the nozzle 3 is hinged to the bottle body 1, allowing the nozzle 3 to rotate flexibly and facilitating disassembly and assembly. Meanwhile, the other side of the nozzle 3 has an elastic protrusion 31 that engages with a groove 12 on the raised edge 11 at one end of the bottle body 1. This ingenious structural design ensures that the nozzle 3 is firmly fixed to the bottle body 1 after assembly, preventing it from easily falling off, thereby improving the reliability and convenience of the device.

[0028] Preferably, the spray head 3 includes a nozzle 32 and a pressing part 33, the pressing part 33 being disposed on the side near the elastic protrusion 31. This arrangement of the pressing part 33 near the elastic protrusion 31 not only makes operation more convenient—the user only needs to press lightly to trigger the spray—but also, the design of its integration with the elastic protrusion 31 further enhances the stability and ease of use of the connection between the spray head 3 and the bottle body 1, improving the overall user experience.

[0029] Preferably, the nozzle 3 has a third protrusion 34 at one end near the bottle body 1, and the third protrusion 34 has a through hole 341. The inner surface of the bottle body 1 has a second protrusion 13 that mates with the through hole 341. The second protrusion 13 passes through the through hole 341, so that the nozzle 3 is hinged to the bottle body 1. The nozzle 3 has a third protrusion 34 at one end near the bottle body 1, and the third protrusion 34 has a through hole 341; while the inner surface of the bottle body 1 is cleverly provided with a second protrusion 13 that mates with the through hole 341. By having the second protrusion 13 pass through the through hole 341, a stable hinge connection between the nozzle 3 and the bottle body 1 is achieved. This design not only allows the nozzle 3 to rotate flexibly to adapt to different usage angles, but also ensures the firmness of the connection between the nozzle 3 and the bottle body 1, improving the overall stability and durability of the device.

[0030] refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 Both the second protrusion 13 and the third protrusion 34 are elastic structures. The connection between the nozzle 3 and the bottle body 1 adopts an elastic structure design, which gives the nozzle 3 a certain degree of flexibility and adaptability during the hinge process, making it easier to adjust the usage angle, and providing a certain buffering effect when subjected to external impact, thus enhancing the durability and reliability of the device. At the same time, the elastic structure design also facilitates the disassembly and assembly of the nozzle 3, improving the convenience of use.

[0031] A dust cover 4 is also provided at the nozzle 3, and the dust cover 4 is snapped onto one end of the bottle body 1. The dust cover 4 is designed at the nozzle 3 and is snapped onto one end of the bottle body 1. This design effectively protects the nozzle 3 from dust and contaminants, keeping the nozzle 3 clean and hygienic, thus ensuring the hygiene and safety of the spray. At the same time, the snap-on connection makes the dust cover 4 easy to install and remove, facilitating daily maintenance and cleaning by the user, and improving the overall user experience and practicality of the device.

[0032] In one embodiment of this utility model, one end of the bottle body 1 is provided with a stepped surface 14, and the port of the dust cover 4 cooperates with the stepped surface 14 so that the dust cover 4 is snapped onto one end of the bottle body 1. The stepped surface 14 is designed at one end of the bottle body 1 of the nasal spray device. This ingenious design allows the port of the dust cover 4 to be perfectly matched with it, which not only achieves a stable snap-fit ​​of the dust cover 4 onto one end of the bottle body 1, but also makes it easier to open the dust cover 4. When the user needs to use it, he / she only needs to gently lift the port of the dust cover 4 to easily remove it from the stepped surface 14. The operation is simple and quick, greatly improving the convenience of use and user experience.

[0033] In one embodiment of this utility model, the dust cover 4 is an elastic transparent structure. The elastic transparent structure of the dust cover 4 not only allows it to fit snugly against the stepped surface 14 of the bottle body 1, effectively preventing the intrusion of dust and contaminants and keeping the nozzle 3 clean and hygienic; but also allows the user to visually see the status of the nozzle 3, facilitating inspection and maintenance at any time. Furthermore, the elastic structure makes opening and closing the dust cover 4 more flexible and effortless, further enhancing the ease of use and user experience of the device.

[0034] Preferably, the nozzle 3 has a channel 35 inside, which communicates with the connecting pipe 2. The nozzle 3 of the nasal spray device has a channel 35 inside, and this channel 35 is tightly connected to the connecting pipe 2. This design ensures that the liquid in the bottle 1 can smoothly flow into the nozzle 3 through the connecting pipe 2, and then be sprayed out in the form of a mist through the nozzle 32. The connection between the channel 35 and the connecting pipe 2 not only ensures the continuity and stability of the spray, but also improves the efficiency of the device, allowing users to easily and quickly obtain the desired spray effect.

[0035] In one embodiment of this utility model, the upper surface of the pressing part 33 is provided with a friction structure 331 for increasing friction. The upper surface of the pressing part 33 of the nasal spray device is designed with a friction structure 331 to increase friction. This design makes the contact between the user's finger and the pressing part 33 more stable when pressing the nozzle 3, preventing slippage and thus improving the accuracy and stability of pressing. The presence of the friction structure 331 enhances the user experience, making operation easier and smoother, and ensuring good pressing effect even when hands are wet or sweaty.

[0036] Preferably, the nozzle 32 is shaped like a trumpet or a cone.

[0037] Understandably, the nasal spray bottle is designed with a gas-liquid separation structure, such as an inner capsule and a straw. When the nozzle 3 is pressed, the pressure generated by the nitrogen gas pushes the liquid in the inner capsule through the straw to the nozzle 32. During this process, the gas and liquid mix at the nozzle 32 and produce a spray. This gas-liquid separation design allows the gas and liquid to mix continuously and stably and produce a spray when the nozzle 3 is pressed continuously.

[0038] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
