Abstract
The utility model provides a positive and negative pressure adjustable nasal irrigator which comprises a main machine. Under the arrangement of the switch cover, normal saline or special nasal washing liquid in the water storage tank can be supplemented, under the arrangement of the spring, the sealing bead can be towed and jacked, the sealing bead is prevented from naturally falling under the action of gravity, a user only needs to rotate the adjusting knob, the adjusting knob moves downwards along with the rotation of the adjusting knob, and therefore the sealing bead is prevented from falling off. The downward movement of the adjusting knob enables the pressing column to move downwards, the downward movement of the pressing column enables the gap between the sealing bead and the air hole to be enlarged, the gap of the air hole is enlarged, the positive pressure in the water storage tank is reduced, then the flow of normal saline or special nasal washing liquid is reduced, adjustment of the positive pressure is achieved, and use by different users is facilitated. A user only needs to take down the silica gel piece, the silica gel piece is taken down to enable the first connecting pipe to be communicated with the outside, the negative pressure in the waste water tank can be adjusted, and under the cooperation of the adjusting knob, the positive pressure and the negative pressure of the nose washing device can be conveniently adjusted.
