[0042] To further understand the content of the present invention, Figure 1-6 The present invention is described in detail with reference to the accompanying drawings and embodiments.

[0043] Combined with Figure 1-6 A nasal aspirator of this embodiment includes a nasal suction head 1, a dirt storage body 2, a connecting piece 4 and a main body 3. The nasal suction head 1 is provided with a first channel 11 for circulating nasal mucus. In specific applications, the dirt storage body 2 is threadedly connected to the nasal suction head 1. In other embodiments, the dirt storage body 2 and the nasal suction head 1 can be snap-connected or sleeved. The dirt storage body 2 and the nasal suction head 1 form a cavity 25 for holding nasal mucus. The cavity 25 is roughly a cylindrical structure, so that the cavity 25 can hold nasal mucus liquid to the greatest extent, making the capacity of the cavity 25 large. The dirt storage body 2 and the main body 3 are detachably connected by the connecting piece 4. A liquid collecting chamber 41 for collecting liquid is formed between the connecting piece 4 and the dirt storage body 2, and the liquid collecting chamber 41 is connected to the atmosphere. The main body 3 has a power assembly therein, and the power assembly includes an air pump 51, and the air pump 51 has an air suction end and an air exhaust end. The air suction end of the air pump 51 is connected to the cavity 25, and the air exhaust end of the air pump 51 is connected to the liquid collecting chamber 41. In other embodiments, the liquid collecting chamber 41 can be only provided in the main body 3 / sewage storage body 2, or the liquid collecting chamber 41 is provided between the connecting member 4 and the main body 3, or the liquid collecting chamber 41 is provided between the main body 3 and the sewage storage body 2. When the nasal aspirator is exhausted, the gas is discharged into the atmosphere through the liquid collecting chamber 41, so that the nasal fluid and water vapor in the gas are collected in the liquid collecting chamber 41, which is clean and hygienic when used. The air pump 51 exhausts air through the liquid collecting chamber 41, so that the noise of the air pump can be transmitted to the atmosphere through the liquid collecting chamber, and the liquid collecting chamber 41 has a noise reduction function. The liquid collecting chamber 41 is an annular chamber, so that the gas discharged from the air pump 51 can flow in the annular chamber. The annular chamber of the liquid collecting chamber 41 further reduces the noise of the air pump 51.

[0044] In this embodiment, a negative pressure cavity 22 is provided between the connecting member 4 and the dirt storage body 2, and the suction end of the suction pump 51 is connected to the cavity 25 through the negative pressure cavity 22. In other embodiments, the negative pressure cavity 22 may be provided only on the main body 3 / the dirt storage body 2 / the connecting member 4. In other embodiments, the suction end of the suction pump 51 may be directly connected to the cavity 25.

[0045] Combined with Figure 2-4 The connecting member 4 includes a base 44, the edge of the base 44 is provided with a circle of first flanges 42, and the base 44 inside the first flange 42 is provided with a circle of second flanges 43. The dirt storage body 2 is provided with a connecting groove 23, and the connecting groove 23 and the second flange 43 are sleeved together. The second flange 43, the connecting groove 23 and the base 44 in the second flange 43 surround the negative pressure chamber 22. The connecting groove 23 and the second flange 43 are fastened and connected by an intermediate member 45, and the connecting groove 23 and the second flange 43 are sealed without a gap, and the intermediate member 45 can be a rubber ring. After the second flange 43 is connected to the connecting groove 23, the first flange 42, the second flange 43, the dirt storage body 2 on the upper part between the first flange 42 and the second flange 43, and the base 44 between the first flange 42 and the second flange 43 surround the liquid collecting chamber 41. The dirt storage body 2 is provided with a shielding portion 21, and the shielding portion 21 blocks one side of the first flange 42 to prevent the liquid in the liquid collecting chamber 41 from overflowing. The shielding portion 21 shields the liquid collecting chamber 41 to further enhance the noise reduction function of the liquid collecting chamber 41. In other embodiments, the liquid collecting chamber 41 is provided with a sound-absorbing cotton, which can further reduce the noise of the liquid collecting chamber 41.

[0046] The power assembly further includes a pressure relief member 52 , which is in communication with the negative pressure chamber 22 . The pressure relief member 52 is used to inflate the negative pressure chamber 22 , and can change the negative pressure condition in the negative pressure chamber 22 after the nasal aspirator is used.

[0047] A first through hole is provided in the base 44 between the first flange 42 and the second flange 43, and a second through hole and a third through hole are provided in the base 44 within the second flange 43. The first through hole is connected to the exhaust end of the vacuum pump 51, the second through hole is connected to the pressure relief member 52, and the third through hole is connected to the suction end of the vacuum pump 51.

[0048] Combined with Figure 3 , 56, the connector 4 is snap-connected with the main body 3. The connector 4 has a bending piece 48, which is bent at a certain angle relative to the connector 4, and has a snap-on hole groove structure 46. The main body 3 has a bending plate 35, which is at a certain angle relative to the main body 3, and has a snap-on protrusion 33. When the main body 3 is connected to the connector 4, the bending piece 48 fits the bending plate 35 and the snap-on protrusion 33 is snap-on with the snap-on hole groove structure 46, so that the main body 3 is fixedly connected to the connector 4. In other embodiments, the connector 4 is threadedly connected or sleeved with the main body 3. One of the connector 4 and the main body 3 is provided with a positioning protrusion 34, and the other of the connector 4 and the main body 3 is provided with a positioning groove 47. When the connector 4 and the main body 3 are connected, the positioning protrusion 34 and the positioning groove 47 are snap-on to locate the relative position of the connector 4 and the main body 3.

[0049] Combined with Figure 4 , a convex body 24 is provided in the dirt storage body 2, and the convex body 24 is higher than the bottom of the cavity 25. The convex body 24 is provided with a second channel 241 connecting the cavity 25 and the suction end of the negative pressure cavity 22 / the suction pump 51, and the end of the second channel 241 communicating with the cavity 25 is higher than the bottom end of the first channel 11, and the end of the second channel 241 communicating with the cavity 25 is staggered with the bottom end of the first channel 11, so that the snot in the first channel 11 flows directly into the cavity 25, and prevents the snot in the first channel 11 from flowing into the second channel 241. The setting of the convex body 24 has the effect of blocking the snot in the cavity 25 from flowing into the suction end of the negative pressure cavity 22 / the suction pump 51. When the snot in the cavity 25 is full, it flows over the convex body 24 from the second channel 241 into the negative pressure cavity 22, and the suction end of the suction pump 51 will discharge the snot into the liquid collection cavity 41.

[0050] The inclined setting of the first channel 11 is beneficial to the flow of snot in the first channel 11 and is beneficial to the staggered arrangement of the first channel 11 and the second channel 241 .

[0051] The structures of the nose suction head 1, the dirt storage body 2 and the connecting piece 4 are simple, so that the nose suction device is easy to disassemble and clean.

[0052] The main body 3 includes a first shell 31 and a second shell 32, which are connected by snaps or screws, and the first shell 31 and the second shell 32 form a space for accommodating the power assembly. The first shell 31 and the second shell 32 also have a power supply element 53 and a control circuit board 54. In specific applications, the power supply element 53 is a battery. The control circuit board 54 is electrically connected to the power supply element 53 and the power assembly, respectively. The control circuit board 54 is provided with a control button 55, and pressing the control button 55 can turn on or control the operation of the nasal aspirator. The control button 55 is installed on the main body 3 and exposed to the outside of the main body 3.
