Example one

Referring to fig. 1, 2 and 3, the present embodiment has an upper cup 1, a lower elastic bottle 2 and a washing tube 3, and a cup bottom 12 of the cup 1 serves as a cap for the elastic bottle 2. The inner space of the cup body 1 forms a backflow liquid cavity 101 of the embodiment; the inner space formed by the elastic bottle body 2 and the cup bottom 12 of the cup body 1 is used as the stock solution cavity 102 of the present embodiment, the volume of the return solution cavity 101 is similar to the volume of the stock solution cavity 102, and is usually slightly larger than the volume of the stock solution cavity 102, the volume of the stock solution cavity 102 is 260ml in the present embodiment, and the volume of the return solution cavity can be respectively adjusted according to actual needs.

Referring also to fig. 3, the irrigation tube 3 includes a nasal prong 31, an injection tube 32, and a flexible tube 33, which are concentrically arranged, and the nasal prong 31 and the flexible tube 33 are detachably connected to upper and lower ends of the injection tube 32, respectively. In this embodiment, the flushing pipe 3 is vertical, and when the elastic bottle body 2 is squeezed, the flushing pipe 3 sprays water vertically and upwardly. As can be seen in fig. 3, the lower end of the hose 33 is proximate the bottom of the dope chamber 102. In order to completely block the nostrils at the insertion end, the head of the nose plug mouth 31 is in a hollow round table shape.

In this embodiment, the cup body 1 is substantially rectangular (approximately elliptical), the length of the cup body 1 is generally greater than the width of the cup body 1, the upper end of the cup body 1 is a fully open end 10, the cup body 1 is generally made of a hard material, but a soft material may be selected as required.

Referring to fig. 3 and 4, the cup body 1 includes a cup wall 11 and a cup bottom 12, both of which are integrally formed with the injection pipe 32 in this embodiment. As can be seen from fig. 1 and 2, in order to better contact the human body near the human medial point when in use, the cup wall 11 has an arcuate depression 111 in the middle of the front side and the corresponding open end edge of the depression 111 forms a concave arcuate segment 112. The design of the recess 111 and the arcuate section 112 is ergonomic and facilitates a tighter fit of the fully open end 10 of the return fluid chamber 101 to the human central region, thereby further reducing the risk of overflow of return water.

With continued reference to fig. 3, the improved nasal health apparatus of the present embodiment further includes an outer protective sleeve 13, an inner internally threaded sleeve 14, and an air vent sleeve 15. The protective sleeve 13, the internally threaded sleeve 14 and the air hole sleeve 15 are integrally connected to the bottom surface of the cup bottom 12 and extend downward, and their lower ends form free ends.

As can be seen in fig. 3 and 4, the spray tube 32 extends through the center of the cup bottom 12, with its lower end extending into the feed solution chamber 102 and its upper end extending out of the fully open end 10 of the return solution chamber 101.

The lower end of the bottle body 211 is connected with the bottle bottom 22. In general, the mouth 212, the transition section 213 and the bottom 22 are relatively hard, and the body 211 is relatively soft and relatively thin, and has a certain elasticity, so that water can be discharged by squeezing the body 211 during use.

Referring to fig. 3, the external thread of the bottle mouth 212 is fitted into the internal thread of the internally threaded sleeve 14, completing the coupling and mounting of the elastic bottle body 2 and the cup body 1. The upper port of the bottle mouth 212 abuts against the bottom surface of the cup bottom 12, and the elastic bottle body 2 and the part of the cup bottom 12 positioned in the internal thread sleeve 14 jointly form the stock solution cavity 102.

With continued reference to FIG. 4, the air cap 15 is located alongside the lower end of the injection tube 32, and the air cap 15 is also located within the collar defined by the internally threaded sleeve 14. Referring to fig. 5 and 6, the air inlet 16 (shown by a dotted line in fig. 6) of the present embodiment is a connecting hole opened in the cup bottom 12 from bottom to top, and the cup bottom 12 is further opened therein with a horizontal air inlet channel 121, one end of the air inlet channel 121 is communicated with the air inlet 16, and the other end is opened on the outer side surface (as an air inlet end) of the cup bottom 12. Considering that the thickness of the cup bottom 12 is generally small during the injection molding process, and the air inlet channel 121 with a large aperture cannot be directly opened inside the cup bottom 12, referring to fig. 8, in the present embodiment, a radial annular protrusion 120 is disposed on the right side of the cup bottom 12, one end of the annular protrusion 120 extends to the side wall of the injection pipe 32, and the other end extends to the cup wall 11. The circular arc protrusion 120 is a part of the cup bottom 12, and it thickens the cup bottom 12, and the air inlet channel 121 is opened inside the cup bottom 12 corresponding to the circular arc protrusion 120.

With continued reference to FIG. 6, the lower half of the inlet ports 16 form a flare 161, and the upper end of the port sleeve 15 is connected to the lower end of the flare 161. In this embodiment, a check valve assembly is installed in the air hole sleeve 15, and the check valve assembly includes a movable plug 17 and an annular stop collar 18. Referring also to fig. 9, the movable plug 17 has a hollow structure, and includes an upper cylindrical portion 171, a conical portion 172, and a lower cylindrical portion 173, which are integrally formed.

The cross section of the limiting ring 18 is approximately in a trapezoid shape, the limiting ring is clamped at the lower end of the air hole sleeve 15, and the movable plug 17 can be installed in the air hole sleeve 15 in an up-and-down moving mode. When the elastic bottle body 2 is pressed, the movable plug 17 moves upward as a whole, and the conical portion 172 abuts against the bell-shaped opening 161, preventing water in the elastic bottle body 2 from being discharged from the air inlet hole 16 and the air inlet passage 121. After the external force is removed from the extruded elastic bottle body 2, the movable plug 17 falls naturally under the influence of gravity, and at the moment, the air inlet 16 and the air inlet channel 121 of the stock solution cavity 102 are unblocked.

In addition, in order to keep the sanitary property in the idle state, it is necessary to provide the cover cap 19 as shown in fig. 10, and it is necessary to add the decorative cover 130 outside the protective cover 13 for the sake of the aesthetic appearance.
