[0029] This utility model proposes a split-type nasal spray device 100.

[0030] Please see Figures 1 to 3 In one embodiment of this utility model, the split-type nasal spray device 100 includes a suction-spray assembly 1 and a main unit 2. The suction-spray assembly 1 includes a housing 11, a suction part 12, and a spray part 13. The housing 11 has an installation cavity 11a. The suction part 12 and the spray part 13 are connected. The suction part 12 has a suction end exposed in the installation cavity 11a, and the spray part 13 has a spray end exposed in the installation cavity 11a. The main unit 2 includes an air pump 21 and a connecting air pipe 22. The connecting air pipe 22 connects the air pump 21 and the suction-spray assembly 1. The air pump 21 has an air inlet 21a and an air outlet 21b. The connecting air pipe 22 connects the air inlet 21a and the suction part 12. The air outlet 21b connects the air pump 21 and the outside.

[0031] In one embodiment, the suction-spray assembly 1 comprises a housing 11, a suction section 12, and a spray section 13. The housing 11 is made of medical-grade plastic, such as ABS plastic or polypropylene (PP), which has good biocompatibility and chemical resistance, and is easy to process and clean. Both the suction section 12 and the spray section 13 are partially disposed within the mounting cavity 11a of the housing 11, and are located at opposite ends of the mounting cavity 11a. The suction section 12 has a suction end exposed in the mounting cavity 11a, and the spray section 13 has a spray end exposed in the mounting cavity 11a. This arrangement ensures that the two functional modules do not interfere with each other during use, improving the practicality and efficiency of the device. Users can conveniently use the suction end for nasal or oral cleaning, or use the spray end for medication spraying or softening of solidified substances in the nasal cavity. This design allows the device to be used for both daily nasal cleaning and medical treatment, such as medication delivery or nasal care.

[0032] It should be noted that the split-type nasal spray device 100 also includes a main unit 2, which contains an air pump 21 and a connecting air tube 22. The air pump 21 is a small, low-noise medical-grade air pump 21, which has an inhalation port 21a and an exhaust port 21b to ensure a stable airflow supply. The connecting air tube 22 is made of pressure-resistant and oil-resistant rubber or plastic tubing, such as polyurethane or PVC tubing. These materials have good sealing performance and chemical resistance, effectively preventing gas leakage, while also possessing a certain degree of oil resistance to cope with any oil that may be present in the air pump 21 or the air canister. The connecting air tube 22 is connected to the inhalation port 21a and the suction section 12 of the air pump 21 through appropriate connectors and clamping devices to ensure a secure and reliable connection. The air pump 21 is placed in a stable, well-ventilated location. The connecting air pipe 22 connects the air pump 21's intake port 21a to the suction section 12 of the suction-spray assembly 1, while the exhaust port 21b directly connects the air pump 21 to the outside environment for easy exhaust gas discharge. This split design allows the air pump 21 and connecting air pipe 22 to be separated from the suction-spray assembly 1, resulting in more thorough cleaning and disinfection and avoiding the incomplete cleaning problems caused by the complex structure of integrated designs. Furthermore, the pressure-resistant and oil-resistant connecting air pipe 22 ensures the stability and safety of airflow transmission, reducing the risk of gas leakage. The design of the air pump 21's intake port 21a and exhaust port 21b ensures a stable airflow supply and facilitates exhaust gas discharge, improving the practicality and efficiency of the device. This design also reduces maintenance costs, as individual parts can be replaced without replacing the entire device, thus extending the product's lifespan.

[0033] This invention provides a split-type nasal spray device 100. By separating the spray-suction assembly 1 from the main unit 2, the device achieves convenient use and thorough cleaning.

The main unit 2 includes an air pump 21 and a connecting air tube 22. The air pump 21 is connected to the suction section 12 via the connecting air tube 22 for suction. After use, the user can easily disassemble the spray-suction assembly 1 for cleaning without worrying about damage to non-waterproof components such as the air pump 21 and battery, thus achieving thorough cleaning and disinfection. The split design makes cleaning the nasal spray device more convenient, avoiding the incomplete cleaning problems caused by the complex structure of integrated designs. Because the air pump 21 and battery, which are not waterproof, are separated from the suction and spray assembly 1 that requires cleaning, users can thoroughly clean and disinfect the suction and spray assembly 1, effectively preventing bacterial growth, reducing hygiene problems, and improving product hygiene and user experience. Furthermore, the modular design may reduce maintenance costs, as each part can be replaced individually without requiring a complete replacement of the entire device.

[0034] In one embodiment of this utility model, please refer to Figure 3 The suction unit 12 includes a nasal suction chamber 121 and a chamber cover. The chamber cover is connected to the nasal suction chamber 121. The nasal suction chamber 121 is detachably disposed in the mounting cavity 11a. The chamber cover and the nasal suction chamber 121 enclose a buffer cavity 12a. The chamber cover has a nasal suction port 122a, which connects the buffer cavity 12a to the outside.

[0035] In one embodiment, the suction unit 12 includes a nasal aspiration chamber 121 and a cover. The nasal aspiration chamber 121 is designed to be detachably disposed within the mounting cavity 11a for easy cleaning and maintenance by the user after use. The nasal aspiration chamber 121 and the cover are made of medical-grade plastic, such as polypropylene (PP) or ABS plastic. These materials have good biocompatibility and chemical resistance, and are easy to process and clean. The cover is connected to the nasal aspiration chamber 121 by threads, snaps, or adhesives to ensure sealing and stability during use. One end of the nasal aspiration chamber 121 has an aspiration end exposed in the mounting cavity 11a for direct contact with the user's nasal cavity. The aspiration end is designed with a rounded shape to reduce irritation and damage to the nasal cavity. The other end of the cover has a nasal aspiration port 122a, which connects to the buffer cavity 12a and the outside via a pipe or channel. The design of the buffer cavity 12a helps reduce airflow impact during direct inhalation, improving user comfort. The main advantage of this design is that it provides an easily disassembled and cleanable suction unit 12, making maintenance of the nasal spray device more convenient and improving hygiene and safety. The use of medical-grade plastic ensures the device's durability and safety for the human body. The rounded design of the suction tip and the inclusion of a buffer chamber 12a enhance user comfort and reduce nasal irritation, making the device more suitable for sensitive individuals. Furthermore, the modular design allows users to replace the suction unit 12 as needed, extending the product's lifespan and reducing long-term maintenance costs.

[0036] In one embodiment of this utility model, please refer to Figure 3 The shell 11 and the nasal suction chamber 121 enclose an air inhalation channel 11b. The connecting tube 22 connects the air inhalation channel 11b with the air inhalation port 21a. The side wall of the nasal suction chamber 121 has an air inhalation port 21a, which connects the buffer chamber 12a and the air inhalation channel 11b.

[0037] In one embodiment, the housing 11 and the nasal aspiration chamber 121 together form an air intake channel 11b. This air intake channel 11b is a key channel connecting the air tube 22 and the air intake port 21a of the air pump 21, responsible for transmitting airflow from the air pump 21 to the nasal aspiration chamber 121. The dashed line in the figure represents the airflow path from the outside being drawn into the nasal aspiration chamber 121 and the air pump 21. The connecting air tube 22 is made of pressure-resistant and oil-resistant rubber or plastic tubing, such as polyurethane hose or PVC hose. These materials not only have good sealing performance and chemical resistance, but also effectively prevent gas leakage. An air intake port 21a is provided on the side wall of the nasal aspiration chamber 121. This air intake port 21a directly connects the buffer chamber 12a and the air intake channel 11b, ensuring smooth airflow. In application scenarios, such as nasal cleaning or medication treatment, users inhale air through the nasal inhaler 122a. The airflow passes through the inhalation channel 11b and enters the buffer chamber 12a, which then distributes it to the nasal cavity to remove nasal mucus or deliver medication. The main advantage of this design is that it provides a compact, easy-to-operate, and efficient airflow delivery system. By integrating the inhalation channel 11b and the buffer chamber 12a into the side wall of the nasal suction chamber 121, the structure of the device is simplified, and the efficiency and stability of airflow delivery are improved, preventing foreign objects removed from the nasal cavity from entering the air pump 21 through the inhalation channel 11b. Furthermore, this design helps reduce airflow loss during delivery, ensuring that the airflow reaches the nasal cavity with sufficient pressure and flow, improving the cleaning or treatment effect. Simultaneously, the direct connection between the inhaler 21a and the buffer chamber 12a reduces the risk of potential airflow backflow or leakage, enhancing the safety and reliability of the device.

[0038] In one embodiment of this utility model, please refer to Figure 3 and Figure 4 The suction unit 12 also includes a nasal suction head 123, which is connected to the cover 122. The nasal suction head 123 is provided with a nasal suction channel 123a, which connects the buffer chamber 12a and the outside.

[0039] In this embodiment, the suction unit 12 includes a nasal aspirator 123 and a connected cap 122. The nasal aspirator 123 is made of medical-grade silicone, a soft and human-friendly material that ensures no irritation or damage to the user's nasal cavity during use. The nasal aspirator 123 is connected to the cap 122 by threads, snaps, or welding to ensure sealing and stability during use. The nasal aspirator 123 has an internal suction channel 123a that directly connects to the buffer chamber 12a and the outside. This design allows airflow and liquid to flow freely between the buffer chamber 12a and the outside, thus achieving the function of suctioning nasal mucus. When cleaning the nasal cavity, the user can gently insert the nasal aspirator 123 into the nasal cavity. The suction generated by the air pump 21 uses the suction channel 123a to draw nasal mucus into the buffer chamber 12a. This design makes the nasal aspiration process more efficient and hygienic. By using a nasal aspirator 123 made of medical-grade silicone, the safety and comfort of the parts in contact with the human body are ensured. The tight connection between the nasal suction tip 123 and the cap 122, along with the direct connection of the nasal suction channel 123a, improves suction efficiency and reduces the possibility of nasal mucus residue. Furthermore, this design helps reduce pressure fluctuations within the nasal cavity, preventing damage to the nasal mucosa and enhancing user experience and satisfaction.

[0040] In one embodiment of this utility model, please refer to Figure 3 and Figure 4 A liquid storage tank 11c is formed in the mounting cavity 11a. A spray opening 11d is provided on the side wall of the liquid storage tank 11c. The spray part 13 includes an atomizing component 131, which is connected to the housing 11 and is located at the spray opening 11d.

[0041] In one embodiment, the sidewall of the liquid storage tank 11c is designed with a spray opening 11d. The core component of the spray unit 13 is the atomizing component 131, which is connected to the housing 11 and located at the spray opening 11d. The atomizing component 131 can generally be an ultrasonic atomizing element or a heating atomizing element, used to atomize the liquid in the liquid storage tank 11c. In terms of material selection, the liquid storage tank 11c can be made of medical-grade plastic, such as polypropylene (PP) or ABS plastic. These materials have good biocompatibility and chemical resistance, and are easy to process and clean. During implementation, the atomizing component 131 is connected to the housing 11 by threads, snaps, etc., ensuring sealing and stability during use. The spray opening 11d of the liquid storage tank 11c is designed to match the spray opening 11d, allowing the atomized liquid to be sprayed out smoothly. This design improves atomization efficiency and ease of use. By precisely positioning the atomizing component 131 at the spray opening 11d, the atomized liquid can be directly sprayed out, reducing the residue of atomized liquid inside the storage tank 11c and improving atomization efficiency. Simultaneously, the simple and reliable connection between the atomizing component 131 and the housing 11 allows for easy disassembly and cleaning by the user, making maintenance more convenient. Furthermore, the use of medical-grade plastic material for the storage tank 11c not only ensures product safety but also makes the device lighter and more durable.

[0042] In one embodiment of this utility model, please refer to Figure 3 The spray unit 13 also includes a spray power module 133, which is detachably connected to the housing 11 and electrically connected to the atomizing component 131.

[0043] In this embodiment, the spray power module 133 of the spray unit 13 is detachably connected to the housing 11 for easy replacement and maintenance. The spray power module 133 can be designed as an independent unit, electrically connected to the atomizing component 131 via a standard interface, such as a PH2.03P terminal. This design allows users to quickly replace the power module when it runs out of power, without having to replace the entire device, improving ease of use. The spray power module 133 is electrically connected to the atomizing component 131, providing the necessary power to the atomizing component 131 to achieve liquid atomization. The atomizing component 131 can use a dedicated driver chip for a fixed-frequency atomizing plate, which ensures a large atomization volume and stable atomization effect. The atomizing component 131 can use a microporous atomizing plate, which is made of a metal microporous plate and a piezoelectric ceramic plate bonded together. This structure allows the liquid to be atomized under the high-frequency resonant oscillation of the piezoelectric ceramic plate without heating or chemical agents. The main advantage of this design is that it improves the ease of maintenance and service life of the nasal spray device. The detachable spray power module 133 allows users to easily replace the battery without requiring specialized skills or tools, greatly reducing maintenance difficulty and costs. At the same time, this design also improves the flexibility of the device, allowing users to better clean the suction unit 12 and the spray unit 13.

[0044] In one embodiment of this utility model, please refer to Figure 3 and Figure 4 The spray unit 13 also includes an atomizing cover 132, which is detachably connected to the housing 11 and is located at the spray opening 11d.

[0045] In one embodiment, the atomizing cover 132, as an important component of the spray unit 13, is detachably connected to the housing 11 for easy replacement and cleaning by the user. The atomizing cover 132 is typically made of medical-grade materials such as polyvinyl chloride (PVC), polypropylene (PP), polycarbonate (PC), or silicone rubber. These materials have good biocompatibility and chemical resistance, and are easy to process and sterilize. The atomizing cover 132 is designed to fit tightly against the housing 11 to ensure airtightness during spraying. Its connection method can be threaded, snap-fit, or plug-in, which facilitates user operation and ensures connection stability. The atomizing cover 132 is located at the spray opening 11d. An atomizing component 131 is designed between the atomizing cover 132 and the liquid storage tank 11c. The atomizing component 131 is electrically connected to the spray power module 133, responsible for converting electrical energy into atomizing power. The spray opening 11d of the atomizing cover 132 is designed to match the spray direction and flow rate of the atomizing component 131 to ensure optimal atomization effect. In application scenarios, such as when delivering nasal medication, the nebulizer 132 can deliver the atomized medication directly to the user's nasal cavity, improving the delivery efficiency and therapeutic effect.

[0046] In one embodiment of this utility model, please refer to Figure 5 The main unit 2 also includes an air circuit adapter 23, which has an air intake chamber 23a and an air exhaust chamber 23b. The air intake chamber 23a is connected to the air pipe 22 and the air pump 21, and the air exhaust chamber 23b is connected to the air pump 21 and the outside.

[0047] In this embodiment, the airflow adapter 23 of the main unit 2 is a key component. The airflow adapter 23 has an intake chamber 23a and an exhaust chamber 23b, used to connect the air pump 21 to the outside environment. The airflow adapter 23 is typically made of sound-insulating plastic or rubber, materials with good sound insulation and noise reduction capabilities, suitable for use in nasal spray devices. The intake chamber 23a connects the air tube 22 and the air pump 21, while the exhaust chamber 23b connects the air pump 21 to the outside environment, ensuring smooth airflow. The airflow adapter 23 can be connected to the air pump 21 and the connecting air tube 22 via a face-sealed joint or pipe welding, ensuring the stability and sealing of the connection.

[0048] In one embodiment of this utility model, please refer to Figure 5 and Figure 6 The cross-sectional area of ​​the intake chamber 23a in the direction of gas flow of the air pump 21 is larger than the cross-sectional area of ​​the connecting air pipe 22, and the cross-sectional area of ​​the exhaust chamber 23b in the direction of gas flow of the air pump 21 is larger than the cross-sectional area of ​​the exhaust port 21b.

[0049] In one embodiment, the gas path adapter 23 is designed to optimize gas flow efficiency and reduce airflow noise. The cross-sectional area of ​​the intake chamber 23a and the exhaust chamber 23b is designed to be larger than the cross-sectional area of ​​the connecting pipe 22 and the exhaust port 21b. This design helps to reduce pressure loss and noise during airflow, while improving the intake and exhaust efficiency of the air pump 21. The gas path adapter 23 can be made of medical-grade materials such as ABS plastic or polypropylene (PP), which have good mechanical properties and chemical resistance, making them suitable for use in medical devices. In implementation, the intake chamber 23a is connected to the intake port 21a of the air pump 21 via the connecting pipe 22, while the exhaust chamber 23b is connected to the exhaust port 21b of the air pump 21 via the exhaust pipe or directly, thereby achieving smooth airflow. This design allows the exhaust gas generated by the air pump 21 during operation to be directly discharged without accumulating inside the device, ensuring unidirectional airflow and device hygiene. The main benefits of this design include improved airflow efficiency and reduced energy consumption of the air pump 21. By increasing the cross-sectional area of ​​the inhalation chamber 23a and the exhaust chamber 23b, the resistance to airflow can be reduced, thereby lowering the energy consumption and noise of the air pump 21. Simultaneously, this design also helps improve the inhalation and exhaust efficiency of the air pump 21, enabling the nasal spray device to operate more efficiently. Furthermore, a well-designed airflow channel helps reduce wear on the air pump 21, extending the device's lifespan. Optimizing the design of the air path adapter 23 enhances the overall performance of the nasal spray device, while also providing users with a more comfortable and quieter experience.

[0050] In one embodiment of this utility model, please refer to Figure 5 The air circuit adapter 23 is made of EVA or silicone material.

[0051] In this embodiment, the airway adapter 23, as a key component of the nasal spray device, is made of either EVA (ethylene-vinyl acetate copolymer) or silicone. Both materials possess excellent noise reduction properties, flexibility, and chemical resistance, making them suitable for airway connections in medical devices. During implementation, the airway adapter 23 is designed with an inhalation chamber 23a and an exhaust chamber 23b. The cross-sectional area of ​​the inhalation chamber 23a is larger than that of the connecting air tube 22, and the cross-sectional area of ​​the exhaust chamber 23b is larger than that of the exhaust port 21b. This design helps reduce pressure loss and noise during airflow, while simultaneously improving the inhalation and exhaust efficiency of the air pump 21. The airway adapter 23 can be injection molded into the desired shape. EVA airway adapters 23 can be connected using an aseptic EVA tubing connection method, while silicone airway adapters 23 can utilize their high-temperature resistance to form an elastic and flexible body through a vulcanization process. Using EVA or silicone for the gas path adapter 23 ensures its flexibility and durability, while also facilitating sterilization and cleaning, thus improving the hygiene and safety of medical devices.
