Description

Technical Field

[0001] The utility model relates to the technical field of cleaning and care devices, in particular to a nasal suction device. Background Art

[0002] The applicant applied for a Chinese patent document with application number 201920483766.8 on April 10, 2019, which discloses a nasal aspirator, including a shell and a suction nozzle arranged at the front end of the shell, a negative pressure chamber provided in the shell, the suction nozzle is connected to the negative pressure chamber, a container for accommodating nasal mucus is provided in the negative pressure chamber, the shell is movably provided with an isolation component for isolating the suction nozzle from the negative pressure chamber, the rear end of the shell is provided with a negative pressure component for generating a vacuum negative pressure in the negative pressure chamber, and a one-way air valve for connecting the negative pressure chamber to the negative pressure component is provided between the negative pressure component and the negative pressure chamber. Although this patent document can achieve the adsorption of nasal mucus and is convenient to use, it requires a container to be provided in the negative pressure chamber to collect the nasal mucus, which makes the volume of the collected nasal mucus small. Once the nasal mucus in the container leaks into the negative pressure chamber, the nasal mucus can easily enter the one-way air valve, and the cost of the nasal aspirator is high.

[0003] In order to solve the technical defects of the above-mentioned Chinese patent document with application number 201920483766.8, the applicant applied for Chinese patent document with application number 202421131940.X on May 22, 2024, disclosing a nasal aspirator. Although the nasal aspirator solves the problem that mucus is not easy or will not enter the one-way air valve, the nasal aspirator either requires the user to operate with both hands, or requires the use of an external support platform to press the negative pressure drive component to achieve one-handed operation, which is still not convenient to use.

[0004] Therefore, the defects are very obvious and a solution is urgently needed. Utility Model Content

[0022] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0023] like Figure 1 and Figure 2As shown, the utility model provides a nasal suction device, which includes a shell 1, a suction nozzle 2, a control switch 3, a one-way air valve 4 and a negative pressure drive component 5. The shell 1 includes a mounting body 6, an upper conduit 7 arranged in the middle of the upper side of the mounting body 6, a lower conduit 8 arranged in the middle of the lower side of the mounting body 6 and coaxially arranged with the upper conduit 7, and a cylinder 9 connected to the rear edge of the mounting body 6. The suction nozzle 2 is sleeved on the outside of the upper conduit 7, and the suction nozzle 2 is connected to the upper conduit 7. The control switch 3 is installed on the mounting body 6, and the control switch 3 is used to control the on-off of the upper conduit 7 and the lower conduit 8; the negative pressure drive component 5 includes a shell 10 that is detachably sealed and connected to one end of the cylinder 9 away from the mounting body 6, a connecting pipe 11 arranged in the middle of the upper side of the shell 10, a piston 12 linearly slidably connected to the inner wall of the inner cavity of the shell 10, a reset elastic member 13 elastically arranged between the piston 12 and the bottom wall of the shell 10 and The pressing and rotating member 14 is used to drive the piston 12 to move in the inner cavity of the shell 10. The middle part of the pressing and rotating member 14 is rotatably connected to the shell 10. The inner end of the pressing and rotating member 14 extends into the inner cavity of the shell 10 and is drivably connected to the piston 12. The outer end of the pressing and rotating member 14 is located outside the shell 10. A snot receiving chamber 15 is formed between the shell 10 and the cylinder 9. The one-way air valve 4 is installed on the connecting pipe 11. A ring body 16 is provided in the middle part of the lower side of the mounting body 6. The lower conduit 8 is located in the ring body 16. The air outlet of the one-way air valve 4 is connected to the air pipe 17. The top end of the air pipe 17 is located between the lower conduit 8 and the ring body 16. The inner cavity of the shell 10 is unidirectionally connected with the air pipe 17 via the one-way air valve 4, and the air pipe 17 is connected with the snot receiving chamber 15 via the inner cavity of the ring body 16; specifically, the control end of the control switch 3 extends out of the mounting body 6, and the air pipe 17 is sealed and connected to the air outlet of the one-way air valve 4.

[0024] When the user releases the pressure on the control switch 3, the control switch 3 automatically resets and disconnects the nasal discharge port 15 from the nose. In the present application, since the top end of the trachea 17 is located between the lower tube 8 and the ring body 16, the snot receiving chamber 15 has a large capacity for receiving snot, and the snot in the snot receiving chamber 15 is not easy or will not enter the one-way air valve 4 through the trachea 17, so it is not easy for the one-way air valve 4 to be damaged due to the snot entering the one-way air valve 4. In addition, by setting the negative pressure drive component 5 to a press-and-turn structure, it is convenient for the user to operate with one hand, and it is easy to use.

[0025] In this embodiment, a sealing ring 18 is installed on the peripheral side wall of the piston 12 to seal the gap between the piston 12 and the inner wall of the inner cavity of the housing 10. This structural design facilitates the sliding of the piston 12 within the housing 10 to achieve vacuuming of the nasal mucus collection chamber 15.

[0026] In this embodiment, a pull-down rod 19 is provided on the lower side of the piston 12, and a pressing handle 21 is provided on the outer end of the pressing and rotating member 14. The pressing handle 21 is arc-shaped, and a pressing space 22 is defined between the pressing handle 21 and the outer wall of the housing 1. A hook portion 20 is provided on the inner end of the pressing and rotating member 14 for contacting the upper side of the pull-down rod 19. The hook portion 20 is used to apply a downward pulling force to the pull-down rod 19. In actual use, when a user's finger applies a pressing force to the pressing handle 21, the pressing and rotating member 14 rotates, causing the pressing handle 21 to rotate closer to the housing 1. The hook portion 20 applies a downward pulling force to the pull-down rod 19, causing the pull-down rod 19 to move downward with the piston 12 and compress the reset elastic member 13. By reciprocatingly applying a pressing force to the pressing handle 21 and under the action of the reset elastic member 13, the piston 12 reciprocates to draw a vacuum into the mucus collection chamber 15.

[0027] In this embodiment, a rotation clearance hole is defined in the bottom sidewall of the housing 10. The inner end of the pressing and rotating member 14 extends through the rotation clearance hole into the inner cavity of the housing 10, providing rotation space for the pressing and rotating member 14. This structural design makes the pressing and rotating member 14 compact with the housing 10, facilitating the normal operation of the pressing and rotating member 14.

[0028] In this embodiment, a transfer arm 23 is provided on the outer side wall of the housing 10, and the middle portion of the pressing and rotating member 14 is rotatably connected to the transfer arm 23. This structural design facilitates the rotatable connection between the pressing and rotating member 14 and the housing 10.

[0029] In this embodiment, a ridge 24 is provided on the underside of the mounting body 6, located between the lower conduit 8 and the ring body 16. The ridge 24 is designed to abut the top end of the trachea 17, but cannot block the top end of the trachea 17. When the top end of the trachea 17 abuts the ridge 24, a gap is created between the mounting body 6 and the top end of the trachea 17, preventing the sidewall of the mounting body 6 from blocking the top end of the trachea 17.

[0030] In this embodiment, the housing 1 is detachably connected to a cover 25, which is used to cover the suction nozzle 2. When not in use, the cover 25 covers the suction nozzle 2, and the cover 25 plays a protective role for the suction nozzle 2.

[0031] In this embodiment, the resetting elastic member 13 is a spring.

[0032] Specifically, the control switch 3 of the present application can adopt the structure of the isolation component in the Chinese patent document with application number 201920483766.8, which will not be repeated here.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
