As shown in fig. 1 to 7, the disposable adjustable nasal cavity cleaner comprises a cap 1, a sealing cover 2, a main container 3, a three-way joint 4 and an air connector 5 which are arranged in sequence from top to bottom; the bottom of the sleeve cap 1 is arranged in a sleeve cap mounting groove 22 on the upper surface of the sealing cover 2, the top of the sleeve cap 1 protrudes to be of an artificial human engineering structure and is made of flexible materials, so that the sleeve cap is more easily attached to nostrils, and the sleeve cap is divided into adult money and child money according to different using crowds. The sealing cover 2 is in threaded connection with the main container 3 through a connecting thread 36, and the size of liquid atomized particles is adjusted by adjusting the relative height position of the sealing cover 2 and the main container 3. The sealing cover 2 is fixedly provided with a liquid guide pipe 24 which is sleeved outside a hollow air guide column 33 in the main container 3, a gap is reserved between the liquid guide pipe and the air guide column, a through hole at the top end of the sleeve cap 1 is communicated with a liquid guide pipe opening 21 at the top of the liquid guide pipe 24 and an air outlet 32 at the top end of the air guide column 33, and the inner diameter of the air outlet 32 is far smaller than the inner diameter of the bottom of the air guide column 33; the three-way joint 4 comprises an air guide column connecting port 41, a switch connecting port 42 and an air connecting port 43, and is respectively connected with the bottom end of the air guide column 33, the switch 6 and a three-way connecting port 51 at the top of the air connector 5, an air pump connecting port 52 at the bottom of the air connector 6 is connected with an air pump, according to the structure, air in the air pump can form high-speed air flow at the air outlet 32 through the air connector 6, the three-way joint 4 and the air guide column 33, and the high-speed air flow is discharged through the liquid guide pipe orifice 21 and the through hole at the top end of the sleeve cap 1.

Convex strips 34 are arranged on the outer surface of the air guide column 33 along the longitudinal direction, the convex strips 34 are uniformly distributed along the circumferential direction of the air guide column 33, and the outer surface of the convex strips 34 is arranged in contact with the inner surface of the catheter 24. The ribs 34 ensure concentricity of the air guide column 33 and the liquid guide tube 24 on the one hand, and form a stable capillary gap between the air guide column 33 and the liquid guide tube 24 on the other hand, so that the liquid in the main container 3 moves up to the position of the air outlet 32 along the capillary gap, thereby facilitating subsequent atomization of the liquid. In order to improve the sealing of the cleaning device when not in use, the outer surface of the bottom of the air guide column 33 is provided with an annular bottom projection 35, and the outer surface of the bottom projection 35 is in contact with the inner surface of the liquid guide tube 24. When not in use, the sealing cover 2 is rotated to the lowest position relative to the main container 3, and the liquid guide tube 24 is respectively jointed with the top and the bottom of the air guide column 33, thereby preventing liquid leakage.

The first type of the switch 6 is a closed type push switch 61 as shown in fig. 8 and 9, a sealing pad 62 is arranged between the push switch 61 and the switch connecting port 42, and the distance between the sealing pad 62 and the switch connecting port 42 is adjusted by changing the degree of pushing the switch 6, so that the air output at the switch connecting port 42 and the air guide column connecting port 41 is adjusted, and the liquid atomization efficiency at the air outlet 32 is adjusted. The second type of switch is a blind hole switch 63 as shown in fig. 10, the blind hole switch 63 is provided with vent holes corresponding to the positions of the switch connection ports 42, and the amount of air discharged from the air guide column connection port 41 is changed by adjusting the amount of air discharged from the switch connection ports 42 by changing the number of the blind vent holes.

As shown in fig. 11 to 14, a main container stopper 37 is disposed between the connecting threads 36, one end of the main container stopper 37 is tangent to the main container shell 31, the thickness of the main container stopper is gradually increased, and the other end surface of the main container stopper 37 is perpendicular to the tangent plane of the shell 31; the inner side of the sealing cover 2 is provided with a sealing cover limiting block 23 matched with the main container limiting block 37, and the sealing cover limiting block 23 and the main container limiting block 37 have the same shape but the thickness increasing direction is opposite. After the end surfaces of the two tangent planes are screwed to the contact positions, the two limit blocks can prevent the sealing cover 2 and the main container 3 from continuously rotating along the direction, on one hand, the phenomenon that the distance between the liquid guide pipe opening 24 and the air outlet 32 is too large and liquid is difficult to atomize is prevented, on the other hand, the sealing cover 2 is prevented from being separated from the main container 3, and the disposable use of the cleaner is ensured. The main container limiting block 37 and the sealing cover limiting block 23 are the same in number and are distributed uniformly along the circumferential direction of the main container shell 31 and the sealing cover 21, so that the limiting effect is improved.

During the use, the user aims at the nasal cavity with the through-hole at cover cap 1 top, open the air pump, push switch 6, make high-speed gas pass gas outlet 32, after the liquid atomization that the capillary gap that drives between catheter 24 and air guide post 33 moves up, get into the nasal cavity via drain mouth of pipe 21 and cover cap 1 through-hole, adjust the relative altitude position of drain mouth of pipe 21 and gas outlet 32 through rotatory sealed lid 2, adjust liquid atomized particle size, dynamics or the pressing area through adjusting push switch 6, the discharge efficiency of adjustment atomized particle, it can stop liquid atomization to loosen switch 6 after the use.

The present invention has been described above by way of example, but the present invention is not limited to the above-mentioned embodiments, and any modification or variation based on the present invention is within the scope of the present invention.
