[0019] This utility model embodiment provides a nasal aspirator, such as Figures 1 to 4 As shown, the device includes a housing 10, a hose 20, and a pressing member 30. The housing 10 forms a first cavity 1102 with a first opening 1101 and a second cavity 1202 with a second opening 1201. The first opening 1101 is used to connect to an air pump (not shown in the figure), and the second opening 1201 is used to extend into the nasal cavity. The hose 20 is disposed in the first cavity 1102, and both ends of the hose 20 are connected to the first opening 1101 and the second cavity 1202, respectively. The pressing member 30 is disposed on the housing 10 and includes a connector 310, an elastic arm 320, and a clamping member 330 connected in sequence. The connector 310 is connected to the housing 10, the elastic arm 320 is located in the first cavity 1102, and a portion of the clamping member 330 extends out of the first cavity 1102 along the side wall of the housing 10. Pressing the clamping member 330 can squeeze the surface of the hose 20 to reduce the cross-sectional area of ​​the hose 20.

[0020] In this embodiment of the nasal aspirator, during use, the user holds the outer casing 10, with one end having a second opening 1201 inserted into the user's nasal cavity. The first opening 1101 on the outer casing 10 is connected to an air pump. A flexible tube 20 is provided to connect the first opening 1101 and the second cavity 1202, so that the air pump is connected to the second cavity 1202. Under the action of the air pump, secretions in the nasal cavity can be collected along the second opening 1201 into the second cavity 1202. A pressing member 30 is provided on the outer casing 10, and the connector 310 of the pressing member 30 is connected to the outer casing 10 to connect the pressing member 30. The nasal aspirator 20 is fixed to the outer shell 10. When a stronger suction is needed to remove secretions, the user presses the clamping member 330. The elastic arm 320 moves along with the clamping member 330, which squeezes the surface of the hose 20. The cross-sectional area of ​​the hose 20 decreases, the flow velocity increases, and the local pressure decreases. When the user releases the clamping force applied to the clamping member 330, the elastic arm 320 springs back to its initial position, the hose 20 returns to its original position, and the pressure difference drives the surrounding fluid to quickly replenish, causing a temporary increase in the flow velocity at the nasal cavity end, thereby increasing the suction at the second opening 1201 to quickly clear nasal secretions. In this embodiment of the nasal aspirator, the user only needs to hold the outer shell 10 with one hand and press the clamping member 330 to quickly achieve the effect of increasing suction. There is no need to operate the air pump with the other hand, making it simple to operate, convenient to use, and improving the user experience.

[0021] The flexible tube 20 in this embodiment can be made of silicone, which has high elasticity and resilience.
