[0035] The nasal washer body 1 has a mounting groove 110 at the top thereof, an inner thread 111 is provided on the side wall of the mounting groove 110, an air outlet 112 is provided in the mounting groove 110, a first annular stepped groove 120 is formed at the top edge of the nasal washer body 1, and a first positioning groove 121 is provided on the first annular stepped groove 120;

[0036] A nose washing head 2 connected to the nose washing device body 1, a mounting portion 210 is provided at the bottom end of the nose washing head 2, an external thread 211 is provided on the side of the mounting portion 210, the mounting groove 110 and the mounting portion 210 are connected by an internal thread 111 and an external thread 211, and an air inlet hole 212 aligned with the air outlet hole 112 is provided in the mounting portion 210;

[0037] The dust cover 3 is sleeved on the nose washing head 2, and a first positioning protrusion 310 is provided on the inner side of the edge of the opening end of the dust cover 3. The edge of the opening end of the dust cover 3 is sleeved to the first annular stepped groove 120, and the first positioning protrusion 310 falls into the first positioning groove 121.

[0038] See attached Figure 2 and attached Figure 3In the above embodiment, the nasal irrigation device body 1 and the nasal irrigation head 2 are connected by a threaded connection between the mounting groove 110 and the mounting portion 210, and the air outlet 112 of the nasal irrigation device body 1 is aligned with the air inlet 212 of the nasal irrigation head 2, so as to blow gas into the nasal irrigation head 2. The dust cover 3 is sleeved on the nasal irrigation head 2 and connected to the first annular stepped groove 120 of the nasal irrigation device body 1 over the nasal irrigation head 2. Since the appearance of the nasal irrigation device body 1 is elliptical in this embodiment, the dust cover 3 sleeved on the first annular stepped groove 120 cannot be rotated due to the shape limitation of the nasal irrigation device body 1, and can only be pulled out vertically, thereby avoiding the problem of accidentally twisting out the nasal irrigation head 2. In the embodiment, when the dust cover 3 is installed in place, the first positioning protrusion 310 falls into the first positioning groove 121, achieving a certain degree of clamping fixation, and preventing the dust cover 3 from being easily detached.

[0039] See attached Figure 2 and attached Figure 4 In the above embodiment, the bottom edge of the nasal washer body 1 is formed with a second annular stepped groove 130, and the second annular stepped groove 130 is provided with a second positioning groove 131.
