The taking down of the silica gel piece 13 causes the first connecting pipe 11 to communicate with the outside, so that the adjustment of the negative pressure in the wastewater tank 3 is realized.

[0029] In the present embodiment

[0030] When using this nasal irrigator, the water tank 2 can store saline solution or a special nasal irrigation solution, and the wastewater tank 3 can collect wastewater after nasal cavity cleaning. The water tank 2, wastewater tank 3, and main unit 1 are detachable, allowing for the disassembly and cleaning of the water tank 2 and wastewater tank 3. The switch button 4 controls the operation of the pump 6. With the cleaning components, when nasal cavity cleaning is needed, the user holds the main unit 1, inserts the inlet head 16 and outlet head 17 into the nostril, and then presses the switch button 4, at which point the pump 6 starts. With the cooperation of the air outlet pipe 7 and the ventilation column 8, the pump 6 can generate positive pressure in the water storage tank 2. In the initial state, the silicone control valve 14 is in a closed state. When positive pressure is generated in the water storage tank 2, the silicone control valve 14 deforms and expands the small hole, allowing the cleaning solution or saline solution to flow out quickly. The outflowing liquid enters the nasal cavity through the water inlet channel 15 and the water inlet head 16. With the cooperation of the second connecting pipe 12, the pump 6 can generate negative pressure in the wastewater tank 3. After the cleaning solution or saline solution flows in the nasal cavity, it enters the wastewater tank 3 through the water outlet head 17 and the water outlet channel 18, completing the cleaning of the nasal cavity. Water collection enables the user's nasal cavity to be cleaned and moisturized, while avoiding waste of the cleaning solution. An adjustment mechanism allows for replenishment of saline solution or special nasal irrigation solution in the water tank 2 via the switch cover 19. A spring 25 supports the sealing bead 24, preventing it from falling due to gravity. To adjust the positive pressure, the user simply rotates the adjustment knob 20. Rotating the knob 20 causes it to move downwards, which in turn moves the pressing column 23 downwards. The downward movement of 23 causes the gap between the sealing bead 24 and the air hole 21 to increase. The increased gap in the air hole 21 reduces the positive pressure in the water tank 2, thereby reducing the flow rate of physiological saline or special nasal irrigation solution. This allows for adjustment of the positive pressure, making it easier for different users to use and improving the user experience. When it is necessary to adjust the negative pressure, the user only needs to remove the silicone part 13. Removing the silicone part 13 connects the first connecting pipe 11 to the outside, thus adjusting the negative pressure in the wastewater tank 3. With the help of the adjustment knob 20, the positive and negative pressure of the nasal irrigator can be conveniently adjusted.

[0031] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
