Description

Technical Field

[0001] The utility model relates to the field of nasal irrigation, in particular to a nasal irrigation device. Background Art

[0002] The nasal cavity is a vital channel for the human body to communicate with the outside world, alongside the oral cavity. A nasal irrigator can remove harmful substances from the nasal cavity, maintaining a clean environment and enabling normal nasal function, which in turn helps other organs in the body function better. This is particularly important for those with respiratory problems. A nasal irrigator is a tool used to clean the nasal cavity. It delivers a specialized nasal rinse solution into the nostrils, which then flows through the nasal vestibule, sinuses, and nasal passages, bypassing the nasopharynx and exiting either a single nostril or the mouth. Through these pathways, the impact of the saline flow dispels accumulated pathogens and pollutants, restoring the nasal cavity to its normal physiological environment and restoring its self-detoxification function, ultimately protecting the nasal cavity. Nasal irrigators are simple to use, safe, and have no side effects. They can relieve nasal congestion, promote normal breathing, and easily remove nasal secretions.

[0003] However, traditional nasal irrigators, such as the technical solution to be protected by the patent with application number CN201510414600.7 and invention name Nasal Irrigator, do not collect and treat the waste liquid generated after cleaning the nose, which will cause pollution to the surrounding environment.

In this embodiment, each support protrusion 122 is integrally formed with the gas guide cylinder 120 and has a hemispherical structure. A partition plate 130 is provided on the bottle base 110, which divides the container bottle 100 into a liquid storage chamber 104 and a waste liquid chamber 105. The gas guide cylinder 120 is located within the liquid storage chamber 104. In this embodiment, the bottle base 110 and the partition plate 130 are integrally formed.

[0034] The air intake mechanism 200 is located in the receiving groove 101. The air intake mechanism 200 includes an L-shaped air intake pipe 210, an adjusting air pipe 220, an adjusting button 230, and a blocking column 240. One end of the L-shaped air intake pipe 210 is connected to the open end of the air guide cylinder 120. The adjusting air pipe 220 is connected to the side wall of the L-shaped air intake pipe 210 near the end of the air guide cylinder 120. In this embodiment, the adjusting air pipe 220 and the L-shaped air intake pipe 210 are integrally formed. The adjusting button 230 is set on the receiving bottle 100, and the driving end of the adjusting button 230 is connected to the blocking column 240. The adjusting button 230 drives the blocking column 240 to block the air outlet end of the adjusting air pipe 220.

[0035] The flushing core 300 is a hollow cylindrical structure with one end open. It fits snugly within the gas cylinder 120 and forms an interference fit with the cylinder 120 via fastening protrusions 121. The fastening protrusions 121 and supporting protrusions 122 create a siphon chamber (not shown) between the flushing core 300 and the cylinder 120.

The connecting cap 400 and the rinsing nozzle 500 are then placed on the container bottle 100. The air supply pipe of the external air pump is connected through the air guide opening 102 to the end of the L-shaped air inlet pipe 210 away from the air guide cylinder 120. The insertion nozzle 510 is inserted into the nostril. The blocking rod 240 is driven by the adjustment button 230 to block the air outlet end of the adjustment air pipe 220. The external air pump is then activated to introduce high-pressure air into the L-shaped air inlet pipe 210. High-pressure air enters the air guide cylinder 120 through the L-shaped air inlet pipe 210. A negative pressure is created between the air guide cylinder 120 and the irrigating core 300 through the air outlet 103. This negative pressure draws the cleaning liquid from the liquid storage chamber 104 through the siphon chamber and discharges it through the liquid outlet 301, allowing the cleaning liquid to enter the nostrils after passing through the liquid outlet nozzle 410 and the insertion nozzle 510. Waste liquid generated during the irrigating process can flow back into the waste liquid chamber 105 through the reflux holes 501 and the reflux port 401. The nasal irrigator 10 can collect and process the waste liquid generated during the nasal irrigating process, thereby preventing pollution to the surrounding environment.
