Description

Technical Field

[0001] This application relates to the field of nasal irrigator technology, and more particularly to a universal portable non-mixing spray nasal irrigator. Background Technology

[0002] With a significant increase in public health awareness and a rise in the prevalence of nasal diseases such as rhinitis, the nasal irrigator industry has transitioned from initial exploration to rapid growth, with increasingly diverse product types and significantly improved quality. Companies are continuously exploring and innovating in design concepts, material selection, and user experience to better meet market demands. Currently, the nasal irrigator industry has entered a stage of stable development, with consumers gaining a deeper understanding and acceptance of the product, and their demands for product comfort, cleaning efficiency, and portability are also rising.

[0003] Nasal spray irrigators, as mainstream products in the industry, rely on a main unit (containing a motor and water pump) to spray nasal irrigation solution (usually saline) from the tank into one side of the nasal cavity at an appropriate speed and pressure. After circulating through the nasopharynx, it flows out from the other nasal cavity, effectively removing dust, bacteria, and other impurities from the nasal cavity. However, most electric nasal irrigators on the market currently use a left-right compartment design, with the liquid reservoir and wastewater reservoir placed side by side. This layout easily leads to liquid mixing problems—wastewater may flow back into the liquid reservoir during use, causing users to unknowingly use contaminated nasal irrigation solution, resulting in secondary contamination of the nasal cavity.

[0004] Although a few nasal irrigators on the market feature a two-compartment design in an attempt to solve the problem of mixed liquids, these products are rather picky about how they are used. Space is limited when tilted, and even a slight tilt angle can easily cause liquid to spill. Furthermore, since the two-compartment design often only adds a waste liquid tray, the sealing performance is poor, and the problem of mixed liquids remains fundamentally unresolved.

[0005] In summary, existing nasal spray devices still face many challenges in product design and functionality. There is an urgent need to solve the problem of mixed liquids and spillage, improve the product's cleaning efficiency, and enhance the user experience. Utility Model Content

[0006] The purpose of this application is to provide a universal portable non-mixing nasal spray irrigator to solve the problem of mixing and overflow between the wastewater tank and the storage tank in the prior art.

[0007] To achieve the above objectives / to solve the above technical problems, this application adopts the following technical solution:

[0008] On the one hand, this application provides a universal portable non-mixing nasal spray irrigator, comprising:

[0009] The reservoir is used to store nasal wash solution;

[0010] The waste liquid tank is detachably and sealed to the liquid storage tank. The waste liquid tank includes a first tank and a second tank that are interconnected. The first tank and the second tank have different depths. The waste liquid tank is provided with an outlet.

[0011] A nozzle is detachably mounted on the top of the waste liquid tank. The nozzle is equipped with a spray head adapted to the human nasal cavity. The spray head has a spray channel inside. The bottom of the nozzle is equipped with a waste liquid outlet that communicates with the waste liquid tank.

[0012] The spray assembly is sealed to the liquid outlet and is used to atomize and spray the nasal wash solution in the storage tank from the spray channel.

[0013] This design's spray assembly dispenses nasal wash solution from the reservoir through the outlet. Part of the sprayed mist comes into contact with the inner wall of the spray channel and eventually falls into the waste liquid tank. The remaining mist enters the nasal cavity through the spray channel to cleanse it. The waste liquid, under gravity, falls and flows down the outer wall of the spray head through the waste liquid outlet into the waste liquid tank, thus achieving waste liquid collection. The outlet and spray assembly are sealed to prevent the waste liquid from mixing with the nasal wash solution through any gaps. The reservoir and waste liquid tank are also sealed to further prevent mixing.

[0014] Furthermore, the design incorporates two separate waste liquid storage compartments of varying depths, effectively balancing the capacity of the waste liquid storage compartment and the storage compartment. This ensures that, even at significant usage angles, both the waste liquid storage compartment and the storage compartment provide sufficient storage space, effectively preventing the risk of liquid overflow from either compartment.

[0015] Optionally, the bottom of the liquid storage tank has an inwardly protruding air inlet column, the air inlet column has an air inlet chamber with a bottom opening, and the top of the air inlet chamber has an air outlet.

[0016] The spray assembly includes a water suction pipe sleeved on the air intake column, with a gap between the air intake column and the water suction pipe, and a spray hole at the top of the water suction pipe;

[0017] The spray assembly also includes a main unit module connected to the air intake chamber, the main unit module being used to blow in airflow.

[0018] In this design, the nasal wash solution in the reservoir enters the gap between the suction tube and the air intake column through the bottom of the suction tube. During use, airflow is introduced into the air intake chamber via the main unit module. Based on the Venturi effect—that is, when a fluid passes through a constriction zone, the flow velocity increases while the pressure decreases—the air outlet at the top of the air intake column acts as a constriction zone, reducing the pressure at the gap between the suction tube and the air intake column, creating a "vacuum." This pressure difference drives the nasal wash solution in the gap to be drawn to the top of the suction tube, where it impacts the top wall of the suction tube, forming fine water mist particles. These fine water mist particles are then sprayed out through the spray hole located at the top of the suction tube.

[0019] Optionally, the main unit module includes a housing, which is detachably disposed at the bottom of the liquid storage tank. The housing has a venting section with an airflow channel connected to the air inlet chamber. The top of the venting section has a soft rubber plug with an air hole. The housing has an air inlet connected to the airflow channel, and a flexible hose is connected to the air inlet for connecting to an external negative pressure pump main unit.

[0020] In this solution, the main unit module achieves airflow input through an external negative pressure pump. Specifically, the negative pressure pump introduces airflow into the airflow channel through a flexible hose, and the gas enters the intake chamber through the air hole on the soft rubber plug within the airflow channel.

[0021] Optionally, the vent is provided with an air outlet, and the outer shell is provided with a button hole communicating with the air outlet. The button hole is provided with a control component for controlling the opening and closing of the air outlet. The control component includes a touch push rod disposed in the button hole. A semi-circular plug is connected to the touch push rod on one side of the air outlet. A spring is provided between the touch push rod and the outer wall of the vent. By pressing one end of the touch push rod, the spring can be compressed to block the air outlet with the semi-circular plug.

[0022] This solution works by allowing gas to enter the airflow channel and flow out of the outlet when the main module is connected to the negative pressure pump. When nasal rinsing is needed, the user can press one end of the touch lever to seal the outlet with a semi-circular plug. Because the outlet is blocked, airflow is forced through the air holes on the soft rubber plug into the air intake chamber. At this point, the nasal spray enters rinsing mode, spraying rinsing fluid in a mist to clean the nasal cavity. Similarly, when rinsing is complete or needs to be interrupted, the user simply releases the touch lever. Under spring pressure, the touch lever and semi-circular plug quickly return to their initial positions, and the outlet reopens. Airflow then exits the outlet, and the nasal spray exits rinsing mode.

[0023] Optionally, a pressure relief valve is detachably provided at the bottom of the vent, and the pressure relief valve has a pressure relief port.

[0024] In this design, a pressure relief valve is used to adjust the airflow intensity of the negative pressure pump, thereby regulating the impact force of the nasal rinse mist. When the airflow from the negative pressure pump enters the airflow channel, it is split. Part of the airflow continues to flow upwards to generate the nasal rinse mist, while the other part flows downwards and exits through the pressure relief port.

[0025] Optionally, the pressure relief valve includes a valve body axially disposed at the bottom of the vent, and a plurality of fan blades rotatably disposed around the valve body. By rotating the fan blades, the fan blades can block or open the pressure relief port.

[0026] This solution allows for control of the impact force of the nasal wash mist by rotating the fan blades to change the opening degree of the pressure relief port, thus meeting different cleaning needs.

[0027] Optionally, the pressure relief port is inverted conical, and the ventilation section is provided with a cleaning component, which includes a cleaning rod and spiral cleaning blades disposed on the cleaning rod. The cleaning blades are used to clean the inner wall of the ventilation section.

[0028] When the negative pressure pump is operating, airflow enters through the vent and is split. Part of the airflow continues upward to generate the nasal rinse mist, while the other part flows out through the inverted conical pressure relief port. Due to the inverted conical design of the pressure relief port, the airflow generates a reverse vortex as it passes through. This reverse vortex drives the spiral cleaning blades upward. As the cleaning blades move upward, they closely adhere to the inner wall of the vent, scraping off dust and dirt. The scraped-off dust and dirt are then discharged outside the equipment through the pressure relief port along with the downward-flowing airflow. This achieves a self-cleaning function for the inner wall of the vent, preventing blockage of the airflow channel.

[0029] Optionally, the main unit module includes a housing, which is detachably disposed at the bottom of the liquid storage tank. The bottom of the housing is provided with a bottom cover. A PCB board is disposed inside the housing. A battery and a negative pressure pump are connected to the PCB board. The negative pressure pump is connected to the air inlet chamber through the hose connector. The housing is provided with a switch for controlling the opening and closing of the negative pressure pump and a gear switching key for controlling the output power of the negative pressure pump. The housing is also provided with a charging interface connected to the PCB board.

[0030] To meet users' portable needs, this solution's main unit module includes a detachable housing, a PCB board, a battery, and a negative pressure pump housed within the housing. The battery provides DC power, and the built-in negative pressure pump provides airflow. No external negative pressure pump unit is required. Users can control the negative pressure pump's operation via a switch. Switching between speed settings controls the power output, thus controlling the negative pressure pump's output.

[0031] Compared with existing technologies, the beneficial effects achieved by this application are as follows: During use, the atomized nasal wash solution can be smoothly guided and recycled into the waste liquid chamber. The sealed connection between the outlet and the spray assembly prevents mixing between the waste liquid and the nasal wash solution through gaps. The sealed connection between the storage chamber and the waste liquid chamber further eliminates the problem of liquid mixing. Furthermore, the waste liquid chamber adopts a dual-chamber design, namely a first chamber and a second chamber. The first and second chambers have different depths, which effectively balances the capacity of the waste liquid chamber and the storage chamber, ensuring sufficient storage space and greatly reducing the risk of liquid overflow. This allows users a wider range of tilt angles during use, providing a more comfortable posture for consumers using nasal wash products.

[0032] To meet users' needs in different scenarios, this utility model has two detachable main unit module solutions. Users can either connect an external negative pressure pump main unit or use an integrated main unit module solution with built-in power supply and negative pressure pump for convenient portable use.

[0033] Finally, this invention also utilizes a dredging component to clean and maintain the airflow channel. This effectively prevents pipe blockage and greatly improves stability and durability. Attached Figure Description

Detailed Implementation

[0047] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0048] Example 1

[0049] This embodiment describes a universal portable non-mixing nasal spray device, referencing... Figures 1 to 3The universal portable non-mixing nasal spray irrigator in this embodiment includes a reservoir 1 for storing nasal wash solution. A waste liquid reservoir 2 is detachably and sealed to the top of the reservoir 1. The waste liquid reservoir 2 includes a first reservoir 22 and a second reservoir 23 that are interconnected, with different depths. The waste liquid reservoir 2 has an outlet 21. A nozzle 3 is detachably mounted on the top of the waste liquid reservoir 2. The nozzle 3 has a spray head 31 adapted to the human nasal cavity, with a spray channel 32 inside. The bottom of the nozzle 3 has a waste liquid outlet 33 connected to the waste liquid reservoir 2. A spray assembly 4 is sealed to the outlet 21 and is used to atomize and spray the nasal wash solution from the reservoir 1 through the spray channel 32.

[0050] In this embodiment, the spray assembly 4 sprays the nasal wash solution from the storage tank 1 through the outlet 21. Part of the sprayed mist comes into contact with the inner wall of the spray channel 32 and eventually falls down into the waste liquid tank 2. The remaining mist enters the nasal cavity through the spray channel 32 to cleanse it. The cleansed waste liquid falls under gravity and flows down the outer wall of the spray head 31 through the waste liquid outlet 33 into the waste liquid tank 2. This achieves waste liquid collection. The outlet 21 is sealed to the spray assembly 4, preventing the waste liquid from mixing with the nasal wash solution through any gaps. The storage tank and waste liquid tank 2 are also sealed, preventing waste liquid from flowing into the storage tank and avoiding mixing.

[0051] Furthermore, in this embodiment, the waste liquid tank 2 has two compartments, a first compartment 22 and a second compartment 23, with different depths, achieving an effective balance in capacity between the waste liquid tank 2 and the storage tank 1. This ensures that, even at a wide operating angle, the waste liquid tank 2 and the storage tank 1 can still provide sufficient storage space, effectively avoiding the risk of liquid overflow from either compartment. This allows users to have a wider range of tilt angles during use, providing a more comfortable posture for consumers using nasal wash products.

[0052] In this embodiment, the liquid storage tank 1 has an inwardly protruding air intake column 11 at its bottom, and an air intake chamber 12 with a bottom opening inside the air intake column 11. The air intake chamber 12 has an air outlet 13 at its top. The spray assembly 4 includes a water suction pipe 41 sleeved on the air intake column 11, with a gap between the air intake column 11 and the water suction pipe 41. The top of the water suction pipe 41 has a spray hole 411. The spray assembly 4 also includes a main unit module 42 connected to the air intake chamber 12, which is used to blow in airflow.

[0053] In this embodiment, the nasal wash solution in the storage tank 1 can enter the gap between the suction tube 41 and the air intake column 11 through the bottom of the suction tube 41. During use, airflow is input into the air intake chamber 12 via the main unit module 42. According to the Venturi effect, when fluid passes through a constriction section, the flow velocity increases while the pressure decreases. In this embodiment, the air outlet 13 at the top of the air intake column 11 serves as a constriction section, causing the pressure at the gap between the suction tube 41 and the air intake column 11 to decrease, creating a "vacuum." This pressure difference drives the nasal wash solution in the gap to be drawn to the top of the suction tube 41, where it impacts the top wall of the suction tube 41, forming fine water mist particles. These fine water mist particles are then sprayed out through the spray hole 411 located at the top of the suction tube 41.

[0054] refer to Figure 4 In this embodiment, the main unit module 42 achieves airflow input through an external AC (alternating current) negative pressure pump 4215. Specifically, the main unit module 42 includes a housing 4201, which is connected to the bottom of the liquid storage tank 1. A vent 4202 is provided inside the housing 4201, and an airflow channel 42021 is provided inside the vent 4202, which is connected to the air inlet chamber 12. A soft rubber plug 4203 is provided on the top of the vent 4202, and an air hole 42031 is provided on the soft rubber plug 4203. An air inlet 42011 is provided on the housing 4201, which is connected to the airflow channel 42021, and a flexible hose 4204 is connected to the air inlet 42011. The flexible hose 4204 is used to connect to the external AC negative pressure pump 4215.

[0055] During use, the negative pressure pump 4215 main unit introduces airflow into the airflow channel 42021 through the hose 4204. The gas then enters the air intake chamber 12 through the air hole 42031 on the soft rubber plug 4203 within the airflow channel 42021. The airflow generates negative pressure through the fine air holes 42031 on the air intake column 11, drawing the nasal wash solution from the storage tank 1 into the gap between the suction tube 41 and the air intake column 11 through the fine air holes 42031. Subsequently, the nasal wash solution is sprayed out from the spray hole 411 at the top of the suction tube 41 under the action of the airflow, forming a water mist.

[0056] Furthermore, the vent 4202 is provided with an air outlet 42022, and the outer casing 4201 is provided with a button hole 42012 communicating with the air outlet 42022. The button hole 42012 is provided with a control component 5 for controlling the opening and closing of the air outlet 42022. The control component 5 includes a touch push rod 51 disposed in the button hole 42012. A semi-circular plug 52 is connected to the touch push rod 51 on one side of the air outlet 42022. A spring 53 is provided between the touch push rod 51 and the outer wall of the vent 4202. By pressing one end of the touch push rod 51, the spring 53 can be compressed to block the semi-circular plug 52 from the air outlet 42022.

[0057] In this embodiment, when the host module 42 is connected to the negative pressure pump 4215 host, gas enters the airflow channel 42021 and flows out from the air outlet 42022. When nasal cleaning is required, the user can press one end of the touch push rod 51 to block the air outlet 42022 with the semi-circular plug 52. Since the air outlet 42022 is blocked, the airflow can no longer flow out from here, but is forced to enter the air inlet chamber 12 through the air hole 42031 on the soft rubber plug 4203. At this time, the nasal spray irrigator enters the cleaning mode and begins to spray the cleaning liquid in the form of a mist for cleaning the nasal cavity. Similarly, when cleaning is complete or cleaning needs to be interrupted, the user only needs to release the touch push rod 51. Under the action of the spring 53, the touch push rod 51 and the semi-circular plug 52 will quickly return to the initial position, and the air outlet 42022 will open again. At this time, the airflow flows out from the air outlet 42022, and the nasal spray irrigator exits the cleaning mode.

[0058] Since the airflow intensity of the external AC negative pressure pump 4215 in this embodiment is uncontrollable, a pressure relief valve 6 is also used to control the airflow intensity entering the air intake chamber 12. Specifically, the pressure relief valve 6 is detachably installed at the bottom of the ventilation section 4202, and has a pressure relief port 61. By setting the pressure relief valve 6, the airflow intensity of the negative pressure pump 4215 is adjusted, thereby adjusting the impact force of the nasal rinse mist. When the airflow from the negative pressure pump 4215 enters the airflow channel 42021, it will be split. Part of the airflow continues to flow upward and enters the air intake chamber 12 to generate the nasal rinse mist. The other part of the airflow flows downward and flows out through the pressure relief port 61. Furthermore, the pressure relief valve 6 in this embodiment has three models with pressure relief port 61 orifice diameters of 0.75mm, 0.5mm, and 0.25mm, respectively. Users can achieve precise control of the airflow by replacing the pressure relief valve 6 with different pressure relief port 61 orifice diameters.

[0059] refer to Figure 5 and Figure 6 In another embodiment, the pressure relief valve 6 includes a valve body 62 axially disposed at the bottom of the vent 4202, and a plurality of fan blades 63 rotatably disposed around the top of the valve body 62. By rotating the fan blades 63, the fan blades 63 can block or open the pressure relief port 61. In use, the pressure relief valve 6 is first disassembled, and the fan blades 63 are rotated according to actual needs to change the opening degree of the pressure relief port 61, thereby controlling the impact force of the nasal wash mist to meet different cleaning needs. Users do not need multiple pressure relief valves 6 with different pressure relief port 61 orifice diameters, greatly improving the convenience of use.

[0060] refer to Figure 7To ensure the smooth flow of airflow channel 42021, this embodiment also includes a dredging component 7. Specifically, the dredging component 7 includes a dredging rod 71 axially disposed within the airflow channel 42021, with spiral cleaning blades 72 mounted on the rod 71. The cleaning blades 72 contact the inner wall of the ventilation section 4202; in this embodiment, the cleaning blades 72 are brushes. Furthermore, the hydraulic port is inverted conical. When the negative pressure pump 4215 operates, airflow enters and is split through the ventilation section 4202. Part of the airflow continues to flow upward to generate nasal rinse mist, while the other part flows out through the inverted conical pressure relief port 61. Due to the inverted conical design of the pressure relief port 61, the airflow generates a reverse vortex as it passes through. The reverse vortex drives the spiral cleaning blades 72 upward. During this upward movement, the cleaning blades 72 closely adhere to the inner wall of the ventilation section 4202, scraping off dust and dirt. The scraped-off dust and dirt are discharged outside the equipment through the pressure relief port 61 along with the downward airflow. This achieves the self-cleaning function of the inner wall of the ventilation section 4202 and prevents the airflow channel 42021 from becoming blocked.

[0061] Example 2:

[0062] Based on the same inventive concept as Embodiment 1, refer to Figure 1 -to Figure 3 The universal portable non-mixing nasal spray irrigator in this embodiment includes a reservoir 1 for storing nasal wash solution. A waste liquid reservoir 2 is connected to the top of the reservoir 1 via a 540° thread. The waste liquid reservoir 2 has a first chamber 22 and a second chamber 23 on one side relative to the reservoir 1, with different depths. An outlet 21 is provided on the waste liquid reservoir 2. A nozzle 3 is detachably mounted on the top of the waste liquid reservoir 2. The nozzle 3 has a spray head 31 adapted to the human nasal cavity, with a spray channel 32 inside. A waste liquid outlet 33, connected to the waste liquid reservoir 2, is located at the bottom of the nozzle 3. In this embodiment, there are four waste liquid outlets 33, arranged around the bottom of the nozzle 3, allowing the user to quickly pour waste liquid into the waste liquid reservoir 2 regardless of how they hold the product. A spray assembly 4 is sealed to the outlet 21 and is used to atomize and spray the nasal wash solution from the reservoir 1 through the spray channel 32.

[0063] In this embodiment, the liquid storage tank 1 has an inwardly protruding air intake column 11 at its bottom, and an air intake chamber 12 with a bottom opening inside the air intake column 11. The air intake column 11 has a plurality of fine air holes 42031 distributed on it. The spray assembly 4 includes a water suction pipe 41 sleeved on the air intake column 11. The top of the water suction pipe 41 has a spray hole 411, and the side wall has a plurality of fine air holes 42031. The spray assembly 4 also includes a main unit module 42 connected to the air intake chamber 12, and the main unit module 42 is used to blow in airflow.

[0064] refer to Figure 10 and Figure 11Under the same conditions, an excessively large or small inclination angle of the suction pipe 41 may result in insufficient water flow impact force, preventing spraying. Furthermore, under the same test conditions, a greater distance results in a smaller spray volume but a smaller median particle size, indicating finer mist. Conversely, a smaller distance results in a larger spray volume but a larger median particle size, indicating coarser particles.

[0065] In some embodiments, the angle between the water suction pipe 41 and the horizontal plane is 70°-89°, and the distance between the port of the spray hole 411 and the top port of the spray channel 32 is 10um-30um. In this embodiment, the angle between the water suction pipe 41 and the horizontal plane is 86.7°, and the distance between the nozzle 3 and the water suction pipe 41 is 21.5um.

[0066] refer to Figure 8 and Figure 9 To meet users' needs for portable operation, in this embodiment, the main unit module 42 includes a housing 4211, which is detachably disposed at the bottom of the liquid storage tank 1. A bottom cover 4212 is provided at the bottom of the housing 4211 to protect the electronic components inside the housing 4211 from interference and damage from the external environment. Simultaneously, a PCB board 4213 is provided inside the housing 4211, on which a battery 4214 and a negative pressure pump 4215 are connected. The battery 4214 is a lithium battery, which provides a stable DC power supply to the negative pressure pump 4215, enabling it to operate continuously and stably. The negative pressure pump 4215 is tightly connected to the air intake chamber 12 via a hose connector 4216, ensuring that airflow can smoothly enter the air intake chamber 12, thereby generating the water mist required for nasal irrigation. Users no longer need to connect an external negative pressure pump 4215 main unit. To facilitate user operation, the housing 4211 is equipped with a switch 4217 for controlling the on / off state of the negative pressure pump 4215, and a speed control button 4218 for controlling the output power of the negative pressure pump 4215. Users can control the on / off state of the negative pressure pump 4215 according to their needs, and adjust the output level of the negative pressure pump 4215 by switching different speeds, thereby achieving precise control over the impact force of the nasal rinse mist. In addition, the housing 4211 is also equipped with a charging interface 4219 connected to the PCB board 4213. In this embodiment, the charging interface 4219 adopts a Type-C interface, facilitating user charging of the battery 4214 and greatly improving the practicality and convenience of the product.

[0067] In this embodiment, a dust cover 8 is detachably provided on the top of the nozzle 3.

[0068] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this disclosure / application, and these improvements and modifications should also be considered within the protection scope of this disclosure / application.
