Preferably, the air inlet column 24 is staggered with the through hole at the lower end of the suction column 111, so that even if the nasal mucus is sucked into the suction cavity 118 through the air inlet hole 1311 of the flow guide support 13, the nasal mucus will fall to the bottom of the suction cavity 118 and not enter the air inlet column 24, that is, will not directly enter the air pump 25, preventing damage to the air pump 25. In addition, after the suction chamber base 11 is assembled with the upper end of the body 2, the lower side wall 115 of the suction chamber base 11 abuts against the outer periphery of the upper end surface of the body 2, and the lower bottom surface of the suction chamber base 11, the lower side wall 115, the annular clamping wall 116, and the upper end surface of the body 2 form an air outlet cavity 119; the lower side wall 115 is provided with an air outlet hole 1151, and the air outlet 26 is arranged in the air outlet cavity 119 and on the upper end surface of the body 2; the air outlet 26 is connected to the air pump 25 in the body 2.

[0037] As a preferred scheme of the flow guide support 13 of the present embodiment, please refer to Figure 8The guide support 13 comprises a support body 131 and two arc-shaped baffle plates 132. The support body 131 is internally provided with an air passage. The arc-shaped baffle plate 132 is formed with a baffle cavity 130. The two arc-shaped baffle plates 132 are respectively vertically arranged on the side walls on the two sides of the support body 131 and open outward, so that the baffle cavity 130 is directly communicated with the suction bin 10. The side walls of the two support bodies 131 are respectively provided with suction holes 1311 at positions corresponding to the arc-shaped baffle plates 132. The suction holes 1311 are communicated with the air passage and the baffle cavity 130. The two arc-shaped baffle plates 132 and the outer side surfaces of the support body 131 form a guide groove 133. The lower end of the support body 131 is detachably assembled on the suction column 111 and communicated with the suction column 111. In the embodiment, the arc-shaped baffle plates 132 are respectively arranged on the side walls on the two sides of the support body 131. The arc-shaped baffle plates 132 open outward on the support body 131, i.e. the upper and lower ends of each arc-shaped baffle plate 132 are respectively inclined upward and downward from the support body 131. The two arc-shaped baffle plates 132 and the outer side surfaces of the support body 131 form the guide groove 133. The guide support 13 can block and guide the nasal discharge sucked from the suction nozzle 14. When the nasal aspirator sucks the nasal discharge, the nasal discharge falls on the upper part of the two arc-shaped baffle plates 132 or directly falls into the two guide grooves 133. The two arc-shaped baffle plates 132 block the nasal discharge from falling into the baffle cavity 130 and prevent the nasal discharge from being sucked into the suction hole 1311. At the same time, the inclined ends of the two arc-shaped baffle plates 132 and the guide effect of the two guide grooves 133 accelerate the guide of the nasal discharge, so that the nasal discharge quickly falls down and is further prevented from being sucked into the suction hole 1311.

[0038] As a preferred scheme of the specific structure of the guide support 13 of the embodiment, please refer to Figure 8The two arc-shaped flow baffles 132 each include a first flow baffle 1321, a second flow baffle 1322, and a third flow baffle 1323. By designing the structure of the arc-shaped flow baffles 132, the snot is prevented from being sucked into the air inlet hole 1311 in multiple ways. The first flow baffle 1321 is arranged on the side wall of the bracket body 131, the first flow baffle 1321 is arc-shaped, and the air inlet hole 1311 is arranged at the corresponding position of the bracket body 131 and the first flow baffle 1321. The two sides of the first flow baffle 1321 are respectively extended to protrude from the side wall of the bracket body 131, so that the first flow baffles 132 of the two arc-shaped flow baffles 132 are separated from each other, and the side wall of the bracket body 131 is enclosed to form two flow guide grooves 133. That is, the two arc-shaped flow baffles 132 are spaced apart from each other, and the two sides of the two arc-shaped flow baffles 132 are enclosed with the side wall of the bracket body 131 to form two flow guide grooves 133. The snot falling on the flow guide bracket 13 is guided by the flow guide effect of the two flow guide grooves 133, and the air inlet hole 1311 is isolated at the same time, so that the snot is prevented from being sucked into the air inlet hole 1311 during the falling process. The second flow baffle 1322 is arranged at the upper end of the first flow baffle 1321 and is arranged outwardly and upwardly from the first flow baffle 1321, so that the snot falling on the second flow baffle 1322 is blocked and guided to the flow guide groove 133 by the inclined effect, and the snot is prevented from falling to the flow guide cavity 130 or the air inlet hole 1311, thereby avoiding the snot from being sucked into the airway from the air inlet hole 1311.
