[0010] In some embodiments, the notch is provided at one end of the body close to the nasal wash assembly.

[0011] In some embodiments, the nasal wash assembly includes a liquid storage portion for storing liquid, the liquid storage portion is provided with a liquid outlet, the air outlet pipe is provided in the liquid storage portion, and an end of the air outlet channel away from the air outlet is connected to the liquid outlet;

[0012] Wherein, along the direction from the air outlet hole to the liquid outlet, the radial size of the air outlet channel gradually decreases.

[0013] In some embodiments, the nasal wash assembly includes a drainage tube, which is arranged on the outside of the air outlet tube. There is a gap between the drainage tube and the air outlet tube to form a drainage channel, which is used to drain the liquid in the liquid storage part to the liquid outlet.

[0014] In some embodiments, the nasal wash assembly includes a nozzle, which is disposed on the outer peripheral side of the liquid outlet.

[0015] In some embodiments, a sealing portion is provided on a side of the air outlet pipe close to the air outlet hole, and a connecting channel is provided in the sealing portion, and the connecting channel is used to connect the air outlet hole and the air outlet channel;

[0016] Wherein, liquid-absorbing cotton is arranged in the sealing part around the communicating channel.

[0017] In some embodiments, a groove is provided on one side of the sealing portion close to the air outlet pipe, the groove is connected to the connecting channel, the radial dimension of the groove is larger than the radial dimension of the connecting channel, and the absorbent cotton is provided in the groove.

[0018] In some embodiments, the nasal rinser further comprises:

[0019] An energy storage unit, the energy storage unit is arranged in the bracket, and the energy storage unit is provided with a charging port;

[0020] a circuit board, the circuit board being disposed in the bracket and being used to electrically connect the energy storage unit and the pump body;

[0021] Among them, the body is provided with a silicone plug at the charging port. When the charging port is connected to an external power supply, the silicone plug is in a released state to expose the charging port. When the charging port is not connected to an external power supply, the silicone plug is in a blocked state to block the charging port.

[0022] In some embodiments, the nasal wash device further includes a support portion, which is disposed at an end of the body away from the nasal wash assembly, and is a structure made of waterproof material.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] In the technical solution of the present application, the nasal rinser provided herein has an ingeniously designed air intake path, which effectively prevents liquid from being drawn into the nasal rinser during use, thereby preventing damage to the electronic components inside the nasal rinser and further preventing short circuits, fires, and explosions in the internal electronic components. For example, in one aspect, the notch, serving as the starting point of the air intake path, is located on the side of the body. Compared to placing the notch on the bottom of the body, this can more effectively prevent liquid stuck on the body from being drawn into the nasal rinser (since the nasal rinser is generally placed vertically, liquid on the sink is more likely to stick to the bottom of the body), thereby ensuring the dryness of the electronic components inside the nasal rinser and ensuring its safety in use. On the second aspect, the airflow entering through the gap will first flow into the air inlet cavity, and then flow from the air inlet cavity to the accommodating cavity through the first air inlet hole. Compared with the airflow flowing directly from the gap to the accommodating cavity, the air inlet cavity can play a good barrier role for the liquid. Moreover, since the aperture size of the first air inlet hole is relatively small, even if there is liquid in the air inlet cavity, it is highly likely that it will not flow into the accommodating cavity with the airflow, thereby further preventing the liquid from contaminating the electronic components in the accommodating cavity and ensuring the safety of the electronic components. On the third aspect, the pump body (which is an electronic component) is arranged inside the bracket. Compared with directly arranging the pump body in the accommodating cavity, the bracket can play a good barrier role for the liquid, preventing the liquid from flowing directly to the pump body with the airflow, avoiding pollution of the pump body, extending the service life of the pump body, and ensuring the safety of the pump body. In addition, the bracket can also block the liquid that flows back from the air outlet channel.

[0026] The nasal wash device provided in the present application is provided with at least three liquid-proof and liquid-blocking structures, which can effectively prevent liquid from flowing into the electronic components inside the nasal wash device, ensure the safety of the electronic components, and extend the service life of the electronic components.

[0055] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0056] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0057] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or", "and / or" or "and / or" appear in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0058] An electric nasal rinse is a device specifically used to clean the nasal cavity. It usually injects a mild saline solution or a specific nasal wash solution, and then uses an electric motor or air pressure to flush the solution into the nasal cavity, thereby removing dust, pollen, allergens, mucus and other substances in the nasal cavity.

[0059] Most electric nasal irrigators currently on the market do not fully consider the actual usage scenarios, working environment and functional requirements, resulting in the pump body inside the electric nasal irrigator easily sucking in solutions or waste liquids during use, damaging internal electronic components and even causing the risk of short circuit, fire and explosion.

[0060] Based on this, in order to solve the technical problem that the existing nasal wash device 10 is easy to absorb the solution into the interior, causing damage to the internal electronic components, refer to Figures 1 to 6 One embodiment of the present application provides a nasal irrigation device 10, which includes a body 100, a bracket 200, a pump body 300, and a nasal irrigation assembly 400. The body 100 is provided with a notch 110, an air inlet cavity 120, and a receiving cavity 130. The notch 110 is provided on the side of the body 100 and is connected to the air inlet cavity 120. The air inlet cavity 120 is provided with a first air inlet hole 122, which is used to connect the air inlet cavity 120 and the receiving cavity 130. The bracket 200 is provided in the receiving cavity 130 and is provided with a second air inlet hole 210, which is used to connect the receiving cavity 130 with the interior of the bracket 200. The pump body 300 is disposed within the support 200 and is provided with a third air inlet 310 and an air outlet 320. The third air inlet 310 is used to connect the interior of the support 200 with the air outlet 320, and the air outlet 320 is used to discharge the air compressed by the pump body 300. The nasal wash assembly 400 is connected to the body 100 and includes an air outlet pipe 410. The air outlet pipe 410 is provided with an air outlet channel 411, which is connected to the air outlet 320. When the nasal wash device 10 is in operation, the flow path of external air to the nasal wash device 10 is: external environment - notch 110 - air inlet cavity 120 - first air inlet 122 - accommodating cavity 130 - second air inlet 210 - interior of the support 200 - third air inlet 310 - pump body 300 - air outlet 320 - air outlet channel 411.

[0061] Specifically, in this embodiment, the nasal rinser 10 provided herein has an ingeniously designed air intake path, which effectively prevents solution from being drawn into the interior of the nasal rinser 10 during use, thereby preventing damage to the electronic components within the nasal rinser 10 and further preventing short circuits, fires, and explosions in the internal electronic components. For example, in one aspect, the notch 110, serving as the starting point of the air intake path, is located on the side of the body 100. Compared to placing the notch 110 at the bottom of the body 100, this can more effectively prevent liquid from the body 100 from being drawn into the interior of the nasal rinser 10 (since the nasal rinser 10 is generally placed vertically, liquid from the sink is more likely to be drawn to the bottom of the body 100). This helps ensure the dryness of the electronic components within the nasal rinser 10 and its safety in use. Secondly, the airflow entering from the notch 110 will first flow into the air inlet chamber 120, and then flow from the air inlet chamber 120 to the accommodating chamber 130 through the first air inlet hole 122. Compared with the airflow flowing directly from the notch 110 to the accommodating chamber 130, the air inlet chamber 120 can play a good barrier role for liquids. Moreover, since the aperture size of the first air inlet hole 122 is relatively small, even if there is liquid in the air inlet chamber 120, it is highly unlikely that it will flow into the accommodating chamber 130 with the airflow, thereby further preventing the liquid from contaminating the electronic components in the accommodating chamber 130 and ensuring the safety of the electronic components. Thirdly, the pump body 300 (which is an electronic component) is arranged inside the bracket 200. Compared with directly arranging the pump body 300 in the accommodating chamber 130, the bracket 200 can play a good barrier role for liquids, preventing the liquid from flowing directly into the pump body 300 with the airflow, avoiding contamination of the pump body 300, extending the service life of the pump body 300, and ensuring the safety of the pump body 300. In addition, the bracket 200 can also block the liquid that flows back through the air outlet channel 411. In one possible implementation, the pump body 300 is completely sealed in the bracket 200.

[0062] The nasal wash device 10 provided in the present application is provided with at least three liquid-proof and liquid-blocking structures, which can effectively prevent liquid from flowing into the electronic components inside the nasal wash device 10, ensure the safety of the electronic components, and extend the service life of the electronic components.

[0063] In some embodiments, reference Figure 3 and Figure 4 A protrusion 121 is provided in the air inlet cavity 120, and a first air inlet hole 122 is formed on the protrusion 121. By providing the first air inlet hole 122 on the protrusion 121, the height of the first air inlet hole 122 can be increased. Even if there is liquid in the air inlet cavity 120, the outer wall of the protrusion 121 will prevent the liquid from entering the first air inlet hole 122, thereby ensuring the safety of the electronic components inside the nasal washer 10.

[0064] In some embodiments, reference Figure 3 and Figure 4 The notch 110 is provided at one end of the body 100 close to the nasal washing assembly 400. In order to improve the patency of the air intake, the body 100 may be provided with a plurality of notches 110, and external air can flow into the inside of the nasal washing device 10 through the plurality of notches 110 at the same time.

[0065] Specifically, in this embodiment, when the nasal wash device 10 is placed normally and vertically, liquid on the outer wall of the body 100 will flow downward under the action of gravity, resulting in less liquid sticking to the upper part of the body 100. Therefore, the higher the position of the notch 110, the less likely the liquid sticking to the outer wall of the body 100 will flow into the notch 110. At the same time, the higher the notch 110 is, the farther it is from the sink, and liquid accumulated on the sink will not flow into the notch 110.

[0066] In some embodiments, reference Figure 2 and Figure 3 The nasal wash assembly 400 includes a liquid reservoir 420 for storing liquid (e.g., nasal wash solution, saline solution, etc.). The liquid reservoir 420 is provided with a liquid outlet 421. The air outlet tube 410 is disposed within the liquid reservoir 420. The end of the air outlet channel 411 away from the air outlet hole 320 is connected to the liquid outlet 421. The radial dimension of the air outlet channel 411 gradually decreases along the direction from the air outlet hole 320 to the liquid outlet 421.

[0067] Specifically, in this embodiment, according to the Venturi principle, when a high-speed airflow passes through a narrow channel, a negative pressure is formed nearby. The negative pressure can suck the liquid stored in the liquid storage portion 420, so that the liquid can be ejected from the liquid outlet 421 along with the high-speed airflow, thereby enabling the nose to be washed with the liquid.

[0068] In some embodiments, reference Figure 2 and Figure 3 The nasal wash assembly 400 includes a drainage tube 430, which is arranged on the outside of the air outlet tube 410. For example, the drainage tube 430 can be sleeved on the outside of the air outlet tube 410. There is a gap between the drainage tube 430 and the air outlet tube 410 to form a drainage channel 431. The drainage channel 431 is used to drain the liquid in the liquid storage part 420 to the liquid outlet 421.

[0069] Specifically, in this embodiment, the negative pressure created by the high-speed airflow within the air outlet channel 411 can draw the liquid within the liquid storage portion 420, causing the liquid to flow along the drainage channel 431 to the liquid outlet 421. The above structure, on the one hand, can effectively control the amount of liquid flowing out of the liquid outlet 421, preventing excessive liquid from splashing around and wasting it. On the other hand, the narrow drainage channel 431 can increase the flow rate of the liquid while reducing the static pressure of the liquid, thereby ensuring a better rinsing effect on the nasal cavity and improving the gentleness of the liquid flushing.

[0070] In some embodiments, reference Figure 2 and Figure 3 The nasal wash assembly 400 includes a nozzle 440, which is disposed on the outer periphery of the liquid outlet 421. For example, the nozzle 440 can be made of silicone. During actual use, the nozzle 440 can be inserted into the nasal cavity to ensure cleanliness at the liquid outlet 421 and improve the comfort of use of the nasal wash device 10.

[0071] Specifically, in this embodiment, one possible implementation method is that the nozzle 440 can be sleeved on the outer peripheral side of the liquid outlet 421. The sleeve-type connection method makes it convenient to remove the nozzle 440 at any time to facilitate cleaning or replacement of the nozzle 440, thereby ensuring the hygiene and cleanliness of the nozzle 440. Another possible implementation method is that a first magnetic portion is provided inside the nozzle 440, and a second magnetic portion is provided on the outer peripheral side of the liquid outlet 421. Through the cooperation between the first magnetic portion and the second magnetic portion, a magnetic connection of the nozzle 440 at the liquid outlet 421 can be achieved. The magnetic connection method facilitates the automatic installation of the nozzle 440 on the outer peripheral side of the liquid outlet 421, which is convenient to install, easy to operate, and saves time and effort.

[0072] In some embodiments, reference Figure 2 and Figure 3 A sealing portion 500 is provided on one side of the outlet pipe 410 near the outlet hole 320. For example, the sealing portion 500 can be made of silicone. A connecting channel 510 is provided in the sealing portion 500. The connecting channel 510 is used to connect the outlet hole 320 and the outlet channel 411. Liquid-absorbing cotton is provided in the sealing portion 500 around the connecting channel 510.

[0073] Specifically, in this embodiment, by providing a (silicone) sealing portion 500 between the nasal wash assembly 400 and the body 100, the connection seal between the nasal wash assembly 400 and the body 100 can be improved, ensuring that the liquid in the nasal wash assembly 400 does not flow back into the body 100 and cause contamination and damage to the electronic components in the body 100. At the same time, by providing a connecting channel 510 in the sealing portion 500 that connects the air outlet 320 and the air outlet channel 411, the smooth flow of air can be ensured, preventing the sealing portion 500 from blocking the air flow and preventing the normal operation of the nasal wash device 10 from being affected by poor air flow (for example, if the air flow is poor, a good negative pressure cannot be formed at the liquid outlet 421, resulting in poor liquid aspiration effect of the nasal wash device 10, making it impossible for the nasal wash device 10 to spray liquid to clean the nasal cavity).

[0074] To further enhance the waterproofing of the sealing portion 500, absorbent cotton is installed within the sealing portion 500. This absorbent cotton absorbs any backflowing liquid, preventing it from entering the body 100 and contaminating the electronic components. Because the absorbent cotton is made of a loose, porous material, it does not obstruct airflow. One possible implementation involves using a material with a larger pore size to ensure good liquid absorption while also improving its air permeability.

[0075] In some embodiments, a groove (not shown in the figure) is provided on one side of the sealing portion 500 close to the air outlet pipe 410. The groove is connected to the connecting channel 510. The radial dimension of the groove is larger than the radial dimension of the connecting channel 510. The absorbent cotton is arranged in the groove.

[0076] Specifically, in this embodiment, the groove and the connecting channel 510 together form a stepped surface, i.e., the side of the sealing portion 500 closer to the air outlet pipe 410 has a larger cross-sectional area, while the side of the sealing portion 500 farther from the air outlet pipe 410 has a smaller cross-sectional area. This stepped surface allows the absorbent cotton to be installed at the larger cross-sectional area of ​​the sealing portion 500, i.e., the absorbent cotton is installed within the groove, thereby reducing the difficulty of installing and securing the absorbent cotton within the sealing portion 500 and improving the feasibility of the solution. For example, one possible implementation is to directly insert the absorbent cotton into the groove, which is simple and convenient to install.

[0077] In some embodiments, reference Figure 2The nasal washer 10 also includes an energy storage unit 600 (for example, the energy storage unit 600 can be a battery) and a circuit board 700. The energy storage unit 600 is arranged in the bracket 200, and the energy storage unit 600 is provided with a charging port 610. The circuit board 700 is arranged in the bracket 200, and the circuit board 700 is used to electrically connect the energy storage unit 600 and the pump body 300. For example, the energy storage unit 600 and the circuit board 700 can be completely sealed in the bracket 200, and the bracket 200 can prevent liquid from flowing to the energy storage unit 600 and the circuit board 700 to ensure the working safety of the energy storage unit 600 and the circuit board 700. Among them, the body 100 is provided with a silicone plug 620 at the charging port 610. When the charging port 610 is connected to an external power source, the silicone plug 620 is in a released state to expose the charging port 610. When the charging port 610 is not connected to an external power source, the silicone plug 620 is in a blocked state to block the charging port 610.

[0078] Specifically, in this embodiment, a control button may be provided on the exterior of the housing 100, and the control button may control the connection and disconnection between the energy storage unit 600 and the pump body 300 via the circuit board 700. For example, when the nasal irrigation device 10 is used to clean the nasal cavity, the energy storage unit 600 needs to supply power to the pump body 300 to ensure normal operation of the pump body 300. The user may press the control button, causing it to control the flow of current on the circuit board 700, ensuring that the energy storage unit 600 and the pump body 300 are in a state of electrical connection. When the nasal irrigation device 10 is no longer needed to clean the nasal cavity, the energy storage unit 600 no longer needs to supply power to the pump body 300. The user may press the control button again, causing it to control the flow of current on the circuit board 700, ensuring that the energy storage unit 600 and the pump body 300 are in a state of electrical disconnection.

[0079] The energy storage unit 600 is provided with a charging port 610. By connecting the charging port 610 to an external power source, the energy storage unit 600 can be charged to ensure that the nasal rinser 10 can be recycled. When the energy storage unit 600 needs to be charged, the silicone plug 620 at the charging port 610 is removed to facilitate the connection of the charging port 610 to the external power source. After the energy storage unit 600 is charged and the external power source is removed from the charging port 610, the silicone plug 620 is re-fastened to the charging port 610. The silicone plug 620 can effectively prevent foreign matter or liquid from entering the charging port 610, causing blockage of the charging port 610 or contamination and damage to internal electronic components.

[0080] In some embodiments, reference Figures 1 to 3 The nasal irrigation device 10 further includes a support portion 800, which is disposed at one end of the body 100 away from the nasal irrigation assembly 400. The support portion 800 is a structure made of a waterproof material. For example, the support portion 800 can be a structure made of silicone.

[0081] Specifically, in this embodiment, when the nasal rinser 10 is normally placed vertically, the support portion 800 can be used to elevate the nasal rinser 10, preventing it from being contaminated by water remaining on the sink. This also prevents waste liquid or water from entering the device through the USB charging port, thereby preventing water from penetrating the internal electronic components of the nasal rinser 10 and ensuring the safety of the electronic components. Furthermore, the support portion 800 (e.g., a silicone pad) also has a good anti-slip effect, which can improve the stability of the nasal rinser 10 when placed vertically.

[0082] In some embodiments, reference Figure 2 and Figure 4 A first engaging portion 140 is provided on the side of the body 100 near the nasal wash assembly 400, and a second engaging portion 450 is provided on the side of the body 100 near the nasal wash assembly 400. The second engaging portion 450 cooperates with the first engaging portion 140 to achieve a snap connection between the nasal wash assembly 400 and the body 100. For example, the first engaging portion 140 can be a snap-on protrusion, and the second engaging portion 450 can be a snap-on groove. Alternatively, the first engaging portion 140 can be a snap-on groove, and the second engaging portion 450 can be a snap-on protrusion.

[0083] Specifically, in this embodiment, when assembling the nasal wash assembly 400 and the body 100, the second engaging portion 450 is first aligned with the first engaging portion 140, and then force is applied to engage the second engaging portion 450 and the first engaging portion 140, thereby achieving a stable connection between the nasal wash assembly 400 and the body 100. To disassemble the nasal wash assembly 400 and the body 100, the nasal wash assembly 400 is grasped, rotated in the opposite direction, and pulled outward. This allows the second engaging portion 450 and the first engaging portion 140 to separate, thereby separating the nasal wash assembly 400 and the body 100. This snap-fit ​​connection between the nasal wash assembly 400 and the body 100 allows for easy connection and disconnection without the need for additional tools. In daily life, users can assemble and disassemble the nasal wash device 10 on their own, facilitating storage, cleaning, and disinfection.
