Description

Technical Field

[0001] This utility model relates to the field of maternal and infant care technology, specifically to a self-cleaning split-type nasal aspirator. Background Technology

[0002] Infants are prone to colds due to their weaker constitution, often accompanied by runny nose. Before they learn to blow their noses on their own, parents often need to help clean their noses. Otherwise, the dried mucus will form nasal crusts that block the nasal cavity, thus affecting the child's breathing.

[0003] Nasal aspirators, as an auxiliary tool, can remove mucus from an infant's nasal cavity. Most commonly used nasal aspirators are equipped with an electric suction pump, which draws the mucus from the infant's nasal cavity into the suction chamber. However, during use, if there is too much mucus in the suction chamber, it can easily be sucked into the electric suction pump, causing airway blockage and bacterial growth, affecting the long-term use of the nasal aspirator. Furthermore, most nasal aspirators on the market do not have a self-cleaning function. In certain application scenarios, mucus or water may enter the device and come into contact with the internal electronic components, making them difficult to clean and prone to damage, thus limiting their long-term use. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a self-cleaning detachable nasal aspirator. When nasal mucus enters the electric suction pump, the body can be disassembled and placed in water, allowing the suction pump to pump in clean water to clean the nasal mucus, thus achieving self-cleaning of the nasal aspirator.

[0005] A self-cleaning, detachable nasal aspirator includes a body, an inhalation head, and a conduit. The body and the inhalation head are connected via the conduit. The body includes a first housing, an electric inhalation pump, and a battery. The first housing is a sealed hollow structure forming a cavity, and its surface is provided with a first air inlet, a first air outlet, and a waterproof charging port. The first air inlet is detachably connected to the conduit. The electric inhalation pump and the battery are located within the cavity. The electric inhalation pump is electrically connected to the battery. The air inlet of the electric inhalation pump is connected to the first air inlet, and the air outlet of the electric inhalation pump is connected to the first air outlet. The electric inhalation pump is a dual-purpose water / air pump. The waterproof charging port is connected to the battery.

[0006] The self-cleaning detachable nasal aspirator of this invention uses a water-air dual-purpose pump. When nasal mucus enters the inhalation pump, simply disassemble the nasal aspirator, place the main body in clean water, and turn on the electric inhalation pump. The electric inhalation pump will then draw in clean water to clean the pump body, allowing the nasal mucus to flow out with the water. At the same time, the main body (first housing) is designed as a sealed hollow structure to achieve a sealed design. The battery and inhalation pump are located in the receiving cavity to prevent water from entering the receiving cavity and damaging the battery.

[0007] As a preferred embodiment, the housing further includes a control panel and a flexible waterproof layer. The control panel is located within the accommodating cavity and includes control buttons that extend through the housing. The flexible waterproof layer adheres to the housing and covers the outer surface of the control buttons, with the control buttons abutting against the flexible waterproof layer. This flexible waterproof layer seals the housing and control buttons, providing not only good waterproofing but also facilitating the pressing of the control buttons.

[0008] As a preferred embodiment, the control panel further includes a control circuit board and indicator lights. The control circuit board is electrically connected to the electric suction pump and the battery, and the indicator lights abut against the flexible waterproof layer. The control circuit board controls the suction power of the suction pump and the battery switch, while the indicator lights indicate the working status of the nasal aspirator and the battery level.

[0009] As a preferred embodiment, the device also includes a speaker, and the first housing is further provided with a sound outlet. The speaker abuts against the first housing and covers the sound outlet, and the connection between the speaker and the first housing is sealed and fixed with a sealant. When suctioning the nasal passages, the infant may exhibit tension and resistance. Playing music through the speaker can distract the infant and facilitate the suctioning process. The sealant covering the speaker also waterproofs the device.

[0010] As a preferred embodiment, the device further includes a second housing, which is a hollow structure forming a slow-flow cavity. Its surface is provided with a second air inlet and a second air outlet. The first housing and the second housing are detachably connected, with the first air inlet abutting against the second air outlet, and the second air inlet detachably connected to the duct. When airflow enters the slow-flow cavity through the duct, the increased space and decreased flow velocity make it easier to separate nasal mucus carried by the airflow. Under the influence of gravity, the mucus remains within the slow-flow cavity, effectively reducing the amount of mucus entering the inhalation pump.

[0011] As a preferred embodiment, the device body further includes a flow damper located within the flow damping cavity, which isolates the second air inlet and the second air outlet, preventing airflow convection between them. By placing the flow damper on the line connecting the second air inlet and the second air outlet, the residence time of the airflow within the flow damping cavity is increased, preventing the airflow from directly entering the second air outlet from the second air inlet. This separates nasal mucus from the airflow, thereby reducing the amount of nasal mucus entering the inhalation pump and reducing the frequency of inhalation pump cleaning.

[0012] As a preferred embodiment, an exhaust chamber is formed at the connection between the first housing and the second housing, and the first air outlet is located within the exhaust chamber, which is in communication with the outside. Airflow can be guided out of the suction pump through the exhaust chamber.

[0013] As a preferred embodiment, the suction head further includes a suction chamber cover and a suction nozzle connected to the suction chamber cover. The suction chamber cover has a hollow structure to form a suction chamber, and the suction chamber cover is detachably connected to the conduit.

[0014] As a preferred embodiment, the inhalation head includes a flow guide bracket disposed within the suction chamber. One end of the flow guide bracket is connected to the conduit, and the other end is closed. A third air inlet is provided on the side of the flow guide bracket. The flow guide bracket forms a mutually separated baffle cavity and a flow guide groove, with the third air inlet located within the baffle cavity. When nasal mucus enters the suction chamber, it is isolated by the baffle cavity of the flow guide bracket and flows downward along the flow guide groove, preventing it from entering the third air inlet and reducing the amount of nasal mucus carried by the airflow into the inhalation pump.

[0015] As a preferred embodiment, the suction nozzle is angled relative to the suction chamber cover. This angled arrangement facilitates the user inserting the nozzle into the nasal cavity. Attached Figure Description

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0030] like Figure 1-7As shown, the self-cleaning detachable nasal aspirator of this utility model includes a body 1, an air intake head 2, and a conduit 3. The body 1 and the air intake head 2 are detachably connected via the conduit 3. The body 1 includes a first housing 11, a second housing 12, a flow damper 13, an electric air pump 14, a battery 15, a speaker 16, and a control panel. The first housing 11 and the second housing 12 are rectangular hollow structures. The first housing 11 has a first air inlet 111, a first air outlet 112, a waterproof charging port 113, and a music playback port 114. The second housing 12 is a rectangular hollow structure with a second air inlet 121 and a second air outlet 122. The hollow structure inside the first housing 11 forms a sealed accommodating cavity 41, and the hollow structure inside the second housing 12 forms a sealed slow-flow cavity 42. The first housing 11 and the second housing 12 are detachably connected, and the connection point forms an exhaust cavity 43. The first air inlet 111 abuts against the second air outlet 122, and the second air inlet 121 is detachably connected to the conduit 3. The first air outlet 112 is located inside the exhaust cavity 43, and the exhaust cavity 43 is connected to the outside.

[0031] The electric air pump 14, battery 15, horn 16, and control panel are located within the accommodating cavity 41. The air inlet of the electric air pump 14 is connected to the first air inlet 111, and the air outlet of the electric air pump 14 is connected to the first air outlet 112. The battery is connected to a waterproof charging port 113, which can be any of the following interfaces: Type-C, Lightning, or USB. Figure 4 As shown, this embodiment uses a Type-C waterproof charging port. The speaker 16 is placed over the music playback port 114, and the connection between the first housing 11 and the speaker 16 is covered with sealant to make the music playback port waterproof.

[0032] The control panel includes a control circuit board 171, control buttons 172, and indicator lights 173. The control circuit board 171 is electrically connected to the electric air pump 14, battery 15, and horn 16. It can load control programs and control the suction power of the electric air pump 14 and the on / off state of the battery 15 and horn 16. A flexible waterproof layer 5 is also provided outside the first housing 11. In this embodiment, the flexible waterproof layer 5 is made of soft rubber. The flexible waterproof layer 5 is sealed and adhered to the outer surface of the housing 11 and covers the control buttons 172 and indicator lights 173. The control buttons 172 and indicator lights 173 abut against the flexible waterproof layer 5. The indicator lights 173 are used to indicate the working status of the nasal aspirator and the battery level.

[0033] The flow buffer 13 is located inside the flow buffer cavity 42 and is vertically arranged on the line connecting the second air inlet 121 and the second air outlet 122. It separates the second air inlet 121 and the second air outlet 122, avoids airflow convection between the second air inlet 121 and the second air outlet 122, reduces the airflow velocity in the flow buffer cavity 42, and causes the nasal mucus carried by the airflow to fall into the flow buffer cavity 42, preventing it from entering the electric inhalation pump 14.

[0034] like Figure 8-9 As shown, the suction head 2 includes a nozzle 21, a flow guide bracket 22, and a suction chamber cover 23. The suction chamber cover 23 has a hollow structure, forming a suction chamber 44. The flow guide bracket 22 is located inside the suction chamber 44, with one end connected to the second air inlet 121 via a conduit 3, and the other end closed. A third air inlet 221 is provided on the side of the flow guide bracket 22. The flow guide bracket 22 forms mutually separated flow-blocking cavities 222 and flow-guiding grooves 223. The third air inlet 221 is located inside the flow-blocking cavity 222. Specifically, the flow guide bracket 22 includes a bracket body 224 and two arc-shaped flow-blocking plates 225. The two arc-shaped flow-blocking plates 225 are respectively vertically arranged on the side walls on both sides of the bracket body 224 and have their openings facing outward to form the flow-blocking cavity 222. The bracket body 224 and the two arc-shaped flow-blocking plates 225 enclose each other to form a flow-guiding groove 223. Each bow-shaped baffle 225 includes a first baffle 2251, a second baffle 2252, and a third baffle 2253. The first baffle 2251 is disposed on the side wall of the support body 224, and the third air inlet 221 is opened at the corresponding position of the support body 224 and the first baffle 2251. The two sides of the first baffle 2251 extend outward toward the support body 224 to form the second baffle 2252 and the third baffle 2253, respectively. Preferably, the second baffle 2252 is larger than the third baffle 2253, and the side of the second baffle 2252 away from the support body 224 extends downward at an angle toward the side closer to the support body 224, while the side of the third baffle 2253 close to the support body 224 extends downward at an angle toward the side away from the support body 224. When nasal mucus enters the suction chamber 44, it is isolated by the bow-shaped baffle 225 of the flow guide 22 and guided downward through the flow channel 223. This allows the flow guide 22 to block and guide the nasal mucus, reducing the amount of nasal mucus entering the cannula 3, thereby reducing the number of times the electric air pump 14 is blocked by nasal mucus and reducing the frequency of cleaning the electric air pump 14. In addition, the shape and size of the second baffle 2252 are designed so that even if nasal mucus falls on the second baffle 2252, it can easily and quickly flow into the flow channel 223, avoiding entering the baffle cavity 222. The shape of the third baffle 2253 is designed so that even if nasal mucus falls on the third baffle 2253, it can easily flow downward into the suction chamber 44.

[0035] The electric suction pump 14 of this invention is a dual-purpose water and air pump. When nasal mucus flows into the electric suction pump 14, simply place the main body 1 directly into water and turn on the electric suction pump 14. If the second housing 12 is removed at this time, clean water enters the electric suction pump 14 from the first air inlet 111 and is pumped out of the electric suction pump 14 from the first air outlet 112, completing the self-cleaning of the electric suction pump 14. If the second housing 12 is not removed, clean water enters the slow-flow chamber 42 from the second air inlet 121, then enters the electric suction pump 14 from the first air inlet 111, and is pumped out of the electric suction pump 14 from the first air outlet 112, and is discharged from the main body 1 from the exhaust chamber 43, simultaneously achieving self-cleaning of both the electric suction pump 14 and the slow-flow chamber 42. The horn 16 can distract the baby's attention with sound and light, making the nasal aspiration process time-saving and labor-saving. The waterproof charging port 131 is used to charge the battery 15. The indicator light 173 is used to indicate the working status of the nasal aspirator and the battery level. Furthermore, the specific structural design of the guide bracket 22 enables the nasal aspirator of this invention to effectively reduce the amount of nasal mucus entering the electric aspirator 14 during the nasal aspiration process, thereby reducing the number of times the electric aspirator 14 becomes blocked and the frequency of cleaning required.

[0036] The above-described embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. For those skilled in the art, various modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
