[0033] This invention proposes a nasal aspirator that aims to provide sufficient suction through an impeller assembly to achieve the nasal aspiration effect while effectively reducing noise.

[0034] Please see Figures 1 to 3 In one embodiment of this utility model, the nasal aspirator 100 includes:

[0035] The fuselage 1 has a first opening 111 and a second opening 112 on its outer peripheral wall, and an airflow channel connecting the first opening 11 and the second opening 12 is formed inside the fuselage 1.

[0036] Nasal suction component 2, which is detachably connected to the body 1, and a first cavity 211 with an inlet 2111 and an outlet 2211 at both ends is formed in the nasal suction component 2, and the outlet 2211 is connected to the first opening 111;

[0037] Impeller assembly 3 is disposed on the inner periphery of the second opening 112. The impeller assembly 3 is controlled to rotate to drive airflow from the inlet 2111 into the first cavity 211 and out from the second opening 112 to suck foreign objects into the first cavity 211.

[0038] Control component 4 is installed inside the body 1 and electrically connected to the impeller assembly 3.

[0039] In this embodiment, the nasal aspirator 100 includes a body 1, a nasal aspiration assembly 2, and an impeller assembly 3. The outer peripheral wall of the body 1 has a first opening 111 and a second opening 112, and an airflow channel 15 is formed within the body 1 connecting the first opening 111 and the second opening 112. The nasal aspiration assembly 2 is detachably connected to the body 1. The impeller assembly 3 is located on the inner periphery of the second opening 112. Controlling the rotation of the impeller assembly 3 drives airflow from the inlet 2111 into the nasal aspiration assembly 2 and out through the second opening 112, thereby drawing foreign objects into the nasal aspiration assembly 2. When in use, the inlet 2111 of the nasal aspirator 2 is aligned with the user's nasal cavity. When the impeller assembly 3 rotates, it generates a sufficiently large airflow. Finally, the suction force can smoothly draw foreign objects into the first cavity 211 of the nasal aspirator 2, while the airflow is discharged through the second opening 112. The suction force generated by the rotation of the impeller assembly 3 is transmitted through the first cavity 211 and the airflow channel 15 to realize the adsorption function of the nasal aspirator 2. Furthermore, the impeller assembly 3 generates low noise during operation, ensuring comfort and improving the user's experience during use.

[0040] Specifically, the nasal aspiration assembly 2 forms a first cavity 211 with an inlet 2111 and an outlet 2112 at both ends. The outlet 2112 is connected to the first opening 111 so that suction is generated at the inlet 2111 under the rotation of the impeller assembly 3, thereby sucking foreign objects from the inlet 2111 into the first cavity 211. Furthermore, the nasal aspiration assembly 2 is detachably connected to the outer periphery of the first opening 111, which facilitates the replacement of the nasal aspiration assembly 2 and improves the ease of use of the nasal aspirator 100. In this way, the nasal aspiration assembly 2 can be removed from the body 1 to clean the foreign objects such as nasal mucus that have entered the nasal aspiration assembly 2, so as to ensure the cleanliness and hygiene of the nasal aspirator 100.

[0041] It should be noted that an installation cavity 11 is formed inside the body 1, which connects to the airflow channel 15. The first opening 111 is formed on the top wall of the installation cavity 11, while the second opening 112 is located on the outer peripheral wall of the body 1 and is close to the first opening 111. This ensures that the impeller assembly 3 provides sufficient air intake. When the impeller assembly 3 rotates, it discharges the air in the first cavity 211 to the outside through the exhaust port. After the air is discharged, the impeller assembly 3 draws in the outside gas through the inlet 2111, causing an instantaneous vacuum to be generated in the first cavity 211, forming a negative pressure difference with the outside atmospheric pressure. Under the action of this pressure difference, foreign objects in the patient's nasal cavity are drawn in, thereby achieving the adsorption effect on foreign objects.

[0042] Furthermore, the nasal aspirator 100 also includes a control component 4, which is installed in the mounting cavity 11 and electrically connected to the impeller assembly 3. Under the control of the control component 4, the impeller assembly 3 can be made to work smoothly so as to successfully aspirate foreign objects from the patient's nasal cavity.

[0043] In one implementation, please refer to Figure 1 and Figure 2 The outer peripheral wall of the body 1 is provided with an exhaust channel 12 that communicates with the airflow channel 15. The exhaust channel 12 is installed on the outer periphery of the first opening 111. The impeller assembly 3 has an air intake end 31 and an exhaust end 32. The air intake end 31 is arranged facing the airflow channel 15, and the exhaust end 32 is arranged inside the exhaust channel 15. This is to provide sufficient air intake so that foreign objects can be smoothly sucked into the second cavity 2111.

[0044] In this embodiment, an exhaust channel 12 communicating with the airflow channel 15 is provided on the outer peripheral wall of the body 1. The exhaust channel 12 is installed on the outer periphery of the first opening 111. Meanwhile, the impeller assembly 3 has an air intake end 31 and an exhaust end 32. The air intake end 31 is connected to the airflow channel 15. That is, the air intake end 31 of the impeller assembly 3 is located close to the first opening 111, thereby ensuring that the impeller assembly 3 provides sufficient air intake. Therefore, under the suction of the air intake end 31 of the impeller assembly 3, the suction force generated by the impeller assembly 3 can smoothly suck foreign objects into the first cavity. Inside 211, the adsorption force generated by the rotation of the impeller assembly 3 is transmitted through the first cavity 211 and the airflow channel 15 to realize the adsorption function of the nasal suction assembly 2. The exhaust end 32 is located in the exhaust channel 12, and the air generated by the impeller assembly 2 during operation is discharged from the exhaust channel 12. At this time, when the exhaust channel 12 is pointed at the human body, the air generated by the impeller assembly 2 can blow onto the human body. At this time, the impeller assembly 2 can be used as a fan. When the nasal suction assembly 2 is removed from the body 1, the impeller assembly 2 can draw in more air and realize a larger air volume output from the impeller.

[0045] It should be noted that the impeller assembly 2 is prior art, and this application does not impose any limitations on it.

[0046] In one implementation, please refer to Figure 1 and Figure 2 The exhaust channel 12 is provided with a mounting bracket 13, and the impeller assembly 3 is mounted on the mounting bracket 13. The mounting bracket 13 has an exhaust port, so that the airflow can be smoothly discharged through the exhaust port under the drive of the impeller assembly 3.

[0047] In this embodiment, to facilitate the installation of the impeller assembly 3, a mounting bracket 13 is provided in the exhaust channel 12, and the impeller assembly 3 is mounted on the mounting bracket 13. The mounting bracket 13 is also provided with an exhaust port that connects to the outside. That is, when the impeller assembly 3 rotates, it discharges the air in the first cavity 211 and the airflow channel 15 to the outside through the exhaust port. After the air is discharged, the impeller assembly 3 draws in the outside gas through the inlet 2111, causing an instantaneous vacuum to be generated in the first cavity 211 and the mounting cavity 11, forming a negative pressure difference with the outside atmospheric pressure. Under the action of this pressure difference, foreign objects in the patient's nasal cavity are drawn in, thereby achieving the adsorption effect of foreign objects.

[0048] In one implementation, please refer to Figure 2 and Figure 3 The nasal suction assembly 2 includes a first housing 21 and a second housing 22. The first housing 21 forms a first cavity 211 with an inlet 2111, and the second housing 22 forms a second cavity 221. The bottom wall of the second cavity 221 is provided with the outlet 2211. The first housing 21 is detachably connected to the second housing 22, and the first cavity 211 communicates with the second cavity 221. The second housing 22 is detachably connected to the body 1 on the side away from the first housing 21.

[0049] The nasal aspirator also includes a guide post 5. One end of the guide post 5 is detachably installed on the outer periphery of the outlet 2211, and the other end of the guide post 5 is located in the first cavity 211 and is positioned corresponding to the inlet 2111. The outer peripheral wall of the guide post 5 forms a gap with the inner peripheral wall of the first cavity 211, so that airflow enters the first cavity 211 from the inlet 2111 through the gap, and restricts foreign objects from being discharged from the second cavity 221 through the gap. By intercepting foreign objects in the first housing 21 through the guide post 5, the blockage of the inlet 2111 caused by foreign objects entering the inlet 2111 is effectively prevented, thereby improving the product's performance and extending its service life.

[0050] In this embodiment, to facilitate the collection of foreign objects, the nasal suction assembly 2 includes a first housing 21 and a second housing 22. The first housing 21 forms a first cavity 211 with an inlet 2111, and the second housing 22 forms a second cavity 221. An outlet 2211 is provided on the bottom wall of the second cavity 221. The first housing 21 is detachably connected to the second housing 22 so that the first cavity 211 communicates with the second cavity 221. It should be noted that a through-hole can be provided on the side of the first housing 21 away from the inlet 2111, and similarly, a through-hole can also be provided on the side of the second housing 22 away from the outlet 2211. That is, the through-holes of the first housing 21 and the second housing 22 communicate to achieve communication between the first cavity 211 and the second cavity 221. Foreign objects entering the first cavity 211 will accumulate in the second cavity 221. The second housing 22 is detachably connected to the main body 1 on the side away from the first housing 21.

[0051] Meanwhile, the first housing 21 is detachably connected to the second housing 22, and the second housing 22 is detachably connected to the main body 1. That is, during disassembly, the first housing 21 can be removed from the second housing 22 to facilitate the replacement and cleaning of the first housing 21. The first housing 21 can be detachably connected to the main body 1 by means of clips or the like. Of course, other detachable connection methods are also possible, and this application does not impose any limitations on them. Similarly, the second housing 22 can also be removed from the main body 1 to facilitate the replacement and cleaning of the second housing 22, thus improving the ease of use of the nasal aspirator. The second housing 22 can be detachably connected to the main body 1 by means of clips or the like. Of course, other detachable connection methods are also possible, and this application does not impose any limitations on them.

[0052] Furthermore, to facilitate the interception of foreign objects, the nasal aspirator also includes a guide post 5. One end of the guide post 5 is detachably installed on the outer periphery of the outlet 2211, and the other end of the guide post 5 is located in the first cavity 211 and is positioned corresponding to the inlet 2111. The outer peripheral wall of the guide post 5 forms a gap with the inner peripheral wall of the first cavity 211, so that airflow enters the first cavity 211 from the inlet 2111 through the gap, and restricts foreign objects from being discharged from the second cavity 221 through the gap. Thus, while ensuring that foreign objects can smoothly enter the first cavity 211 through the inlet 2111, the interception mechanism of the guide post 5 also ensures that foreign objects in the first cavity 211 and the second cavity 221 will not be discharged to the inlet 2111 through the gap, thereby avoiding the blockage of the inlet 2111.

[0053] In one implementation, please refer to Figure 2 and Figure 3The inner peripheral wall of the first cavity 211 is provided with a relief recess 2112, which corresponds to the outer peripheral wall of the guide post 5, so that the gap forms a curved channel to further restrict the discharge of foreign objects in the second cavity 221 from the inlet 2111.

[0054] In this embodiment, an avoidance recess 2112 is provided on the inner peripheral wall of the first cavity 211, and the avoidance recess 2112 corresponds to the outer peripheral wall of the guide post 5, so that the gap forms a curved channel. This arrangement facilitates the smooth entry of airflow and foreign objects into the first cavity 211 and the second cavity 221 through the gap, and also effectively restricts the discharge of foreign objects in the second cavity 221 from the inlet 2111 through the gap, thereby effectively preventing the inlet 2111 from being blocked by the backflow of foreign objects, and effectively preventing foreign objects from returning to the patient's nasal cavity.

[0055] In one implementation, please refer to Figure 2 and Figure 3 The guide post 5 includes a mounting section 51 and an intercepting section 52 connected to each other. The outer peripheral wall of the intercepting section 52 forms the gap with the inner peripheral wall of the first cavity 211. A first air passage 511 is formed in the mounting section 51. An air inlet 512 is provided on the outer peripheral wall of the first air passage 511.

[0056] The mounting section 51 is detachably mounted on the outer periphery of the outlet 2211 on the side opposite to the intercepting section 52. The first air passage 511 is connected to the outlet 2211. Thus, with the combination of the mounting section 51 and the intercepting section 52, foreign objects can be intercepted in the second cavity 221 to effectively prevent foreign objects from entering the inlet 2111 or the first air passage 511 or the first cavity 211.

[0057] In this embodiment, the guide post 5 includes a connected mounting section 51 and an intercepting section 52. The intercepting section 52 is located below the inlet 2111, and the outer peripheral wall of the intercepting section 52 forms a gap with the inner peripheral wall of the second cavity 221. That is, the recess 2112 avoids the outer peripheral wall of the intercepting section 52, so that the gap forms a curved channel. A first air passage 511 is formed in the mounting section 51, and an air inlet 512 is provided on the outer peripheral wall of the first air passage 511. 52 is positioned above the air inlet 512 to block the air inlet 512, thereby preventing foreign objects from entering the first air passage 511 from the air inlet 512 and thus preventing foreign objects from contaminating the first air passage 511. That is, the airflow enters from the inlet 2111 under the rotation of the impeller assembly 3, and enters the first cavity 211 and the second cavity 221 through the gap. Then, it enters the mounting cavity 11 through the air inlet 512 and the first air passage 511, and finally exits to the outside from the exhaust port.

[0058] It should be noted that the guide post 5 is a one-piece molded structure, which ensures structural strength and stability.

[0059] In one implementation, please refer to Figure 2 and Figure 3 The air inlet 512 is provided in multiple ways, and the multiple air inlets 512 are spaced apart on the outer peripheral wall of the mounting section 51. By providing multiple air inlets 512, the smooth flow of air can be ensured, and sufficient suction can be ensured at the inlet 2111, so that foreign objects can be smoothly sucked into the second cavity 221.

[0060] Meanwhile, the interception section 52 is conical in shape, and the interception section 52 is gradually tapered from the end near the installation section 51 to the end away from the installation section 51. This design ensures that foreign objects can smoothly enter the first cavity 211 under the action of suction, while also effectively preventing foreign objects from entering the inlet 2111, the first airway 511, or the airflow channel 15.

[0061] Specifically, the intercepting section 52 is gradually tapered from the end near the mounting section 51 to the end away from the mounting section 51. That is, the cross-sectional area of ​​the intercepting section 52 on the side near the mounting section 51 is greater than the cross-sectional area of ​​the intercepting section 52 away from the mounting section 51. This arrangement effectively prevents foreign objects that have entered the first cavity 211 and the second cavity 221 from entering the air inlet.

[0062] Furthermore, the interception section 52 is conical in shape, that is, the surface of the interception section 52 is inclined away from the mounting section 51. When foreign objects enter from the inlet 2111 and fall onto the surface of the interception section 52 away from the mounting section 51, they can also pass smoothly through the gap under the guidance of this surface and enter the first cavity 211 and the second cavity 221.

[0063] In one implementation, please refer to Figure 2 and Figure 3 The nasal aspirator also includes a guide tube 6, in which a second airway 61 is formed. One side of the guide tube 6 is installed on the bottom wall of the second cavity 221, one side of the second airway 61 is connected to the outlet 2211, and the other side of the second airway 61 is connected to the first airway 511.

[0064] In this embodiment, the nasal aspirator also includes a guide tube 6, in which a second airway 61 is formed. One side of the guide tube 6 is installed on the bottom wall of the second cavity 221. One side of the second airway 61 is connected to the outlet 2211, and the other side of the second airway 61 is connected to the first airway 511. That is, the airflow entering the first cavity 211 enters the first airway 511, the second airway 61, and the mounting cavity 11 in sequence through the air inlet 512. It should be noted that the mounting section 51 is detachably installed on the guide tube 6. That is, the guide post 5 can also be removed and cleaned, thereby ensuring the hygiene of the nasal aspirator.

[0065] Furthermore, the guide tube 6 has a certain length, and the guide post 5 is detachably installed on a part of the guide tube 6. While ensuring suction, this also prevents foreign objects from entering the first air passage 511 and the second air passage 61 through the air inlet 512. It should be noted that the second housing 22 is made of a transparent material, which allows the user to easily observe the specific situation of foreign objects inside the second housing 22, so as to clean the second housing 22 and other components in a timely manner.

[0066] In one implementation, please refer to Figure 2 and Figure 3 The nasal aspirator also includes a filter 7, which is detachably installed between the first opening 111 and the outlet 2211 to intercept foreign objects entering the second airway 61 and prevent them from entering the first cavity 211, thereby avoiding contamination of the impeller assembly 3.

[0067] In this embodiment, the nasal aspirator also includes a filter element 7, which is detachably installed between the first opening 111 and the outlet 2211. It should be noted that at least a portion of the filter element 7 is installed in the second cavity 221, and at least another portion of the filter element 7 protrudes from the mounting cavity 11. Therefore, once a foreign object enters the second airway 61, it can be effectively prevented from entering the mounting cavity 11 by the filtering and interception of the filter element 7. Since the material of the second housing 22 is transparent, it is convenient for the user to observe the specific situation of the foreign object and the filter element 7 in the second housing 22, so as to clean the second housing 22 and other components and replace the filter element 7 in a timely manner. It should be noted that the filter element 7 is existing technology, such as filter cotton, etc., and this application does not impose any restrictions on it here.

[0068] In one embodiment, the nasal aspirator 100 further includes an atomizing component 8, which is disposed on the outer peripheral wall of the body 1 and offset from the impeller assembly 3 on an axis parallel to the body 1. By providing the atomizing component 8, the nasal aspirator 100 has an atomizing function, thereby improving the effectiveness of the nasal aspirator 100.

[0069] In this embodiment, the atomizing component 8 includes a water tank 81, an atomizing plate 82, and a mist-absorbing chamber 83. The water tank 81 is detachably installed in the mounting cavity 11. An mounting port 14 is provided on the outer peripheral wall of the body 1. The mist-absorbing chamber 83 is detachably installed in the mounting port 14 and communicates with the water tank 81. The atomizing plate 82 is disposed between the mist-absorbing chamber 83 and the water tank 81. It should be noted that the water tank 81, the atomizing plate 82, and the mist-absorbing chamber 83 are all prior art, and this application does not impose any limitations on them.
