Abstract
Description
Technical Field
[0001] This utility model relates to the field of nasal cleaning products, and more specifically, to a nasal aspirator. Background Technology
[0002] A nasal aspirator is a tool used to clear nasal secretions and keep the nasal passages clear. It is mostly used in infants and young children. By simulating the action of blowing one's nose, the nasal aspirator uses suction to remove mucus or nasal crusts, which helps babies breathe more easily.
[0003] Nasal aspirators commonly available on the market generally come in two types: manual and electric. Manual nasal aspirators typically consist of a soft tube and a straw with a suction bulb. By squeezing the bulb, air is forced into the tube, thus suctioning out mucus and phlegm. However, the suction power of these suction bulbs is relatively weak, and backflow is common, causing discomfort to the baby. Electric nasal aspirators generally use rechargeable batteries and have higher suction power and automatic expulsion functions. However, electric nasal aspirators tend to be noisier, which can make babies resist them. Utility Model Content

[0026] A preferred embodiment of this utility model is a nasal aspirator, such as... Figure 1-3As shown, the device includes a nasal aspirator 10, an air suction assembly 20, and a trachea 30. The nasal aspirator 10 includes a suction nozzle 11 and a secretion storage box 12 detachably connected to the suction nozzle 11, facilitating cleaning or replacement of the secretion storage box and making it convenient to use. A sealed cavity 13 is provided between the suction nozzle 11 and the secretion storage box 12, ensuring airtightness during nasal aspiration and preventing air leakage, thereby improving suction efficiency. A guide tube 14 extending into the sealed cavity 13 is provided on the suction nozzle 11, allowing secretions to flow smoothly from the suction nozzle 11 into the secretion storage box 12, avoiding the accumulation of secretions inside the nasal aspirator and improving cleaning efficiency. In this embodiment, the guide tube gradually expands from the outside to the inside. One end of the guide tube 14 is connected to the liquid inlet 111 of the suction nozzle 11, and the other end extends towards the upper end of the secretion storage box 12. The side of the suction nozzle 11... The wall is also provided with a first air hole 112 communicating with the sealed cavity 13; the suction assembly 20 includes a vacuum cylinder 21, a piston head 22 that slides with the inner wall of the vacuum cylinder 21, and a handle 23 fixedly connected to the piston head 22; at least a portion of the handle 23 is provided on the outside of the vacuum cylinder 21, allowing the user to easily control the suction force by operating the piston head 22 to adapt to different suction needs; the piston head 22 is airtightly fitted with the inner wall of the vacuum cylinder 21; the vacuum cylinder 21 is also provided with a second air hole 24; the second air hole 24 is connected to the first air hole 112 through an air tube 30; the first air hole 112 and / or the second air hole 24 are provided with a filter membrane 25 to prevent secretions from flowing out; in this embodiment, the filter membrane 25 is a microfiltration membrane, ultrafiltration membrane, or nanofiltration membrane in the prior art, which will not be described in detail here.

Whether it is an infant or an adult, users can adjust the suction force and select the appropriate size of the nasal aspirator tip to meet their needs.
[0027] This nasal aspirator features a clever design. When in use, the inlet of the aspirator tip is aligned with one nostril, and the nostril is blocked by the outer contour of the aspirator tip. Then, by pulling the piston head, the air pressure inside the vacuum cylinder is gradually increased to generate greater suction. This controllable suction allows liquid secretions from the nasal cavity to be drawn from the inlet along the guide tube into the secretion storage box, helping the baby breathe smoothly. By incorporating a filter membrane in the first and / or second air vents, liquid secretions can be effectively prevented from flowing into the vacuum cylinder along the trachea, thus improving the suction effect and providing a better user experience.

By setting two layers of sealing structure, air leakage can be prevented, thereby ensuring the vacuum degree required during the suction process.
[0030] Alternatively, to further enhance the connection and sealing performance between the first sealing ring 214 and the second sealing ring 215, the upper surface of the first sealing ring 214 is provided with a groove 216 that fits tightly with the second sealing ring 215; the second sealing ring can not only position the first sealing ring and the piston head, but also prevent the second sealing ring 215 from falling off due to external force during the reciprocating motion of the piston, ensuring that the sealing ring always stays in the correct position.
[0031] Furthermore, the handle 23 includes a connecting rod 231 fixedly connected to the piston head 22 and a first hand-held part 232 fixedly disposed at the free end of the connecting rod 231; the structure is simple.
[0032] Optionally, the first hand-held part 232 is provided with a first through hole 233 for the fingers or palm to pass through, making it easy for the user to grip and apply force.
[0033] Furthermore, the upper cover 212 has a second through hole 234 in the middle for the connecting rod 231 to pass through and communicate with the vacuum chamber 213; after the connecting rod 231 passes through the second through hole 234, it is fixedly connected to the upper surface of the piston head 22; alternatively, the connecting rod can be fixed to the piston head by means of a clamp and fastening screws.
[0034] Furthermore, the second vent 24 is located at the bottom of the cylinder 211.
[0035] Alternatively, the suction nozzle 11 can be threadedly connected to the secretion storage box 12, or the suction nozzle 11 can also be connected and fixed using a snap-fit structure commonly used in the prior art.
[0036] Furthermore, the 11-head suction nozzle has a bullet-shaped appearance and a smooth surface, and can be used with nostrils of different sizes, making it more comfortable for users.
