Description

Technical Field

[0001] This utility model relates to a rinsing device, and more particularly to a nasal rinsing device for use in the field of rinsing devices. Background Technology

[0002] The nasal cavity, as a vital gateway to the human respiratory system, plays a crucial role in filtering, humidifying, and warming inhaled air. However, the nasal cavity is highly susceptible to external pollutants, allergens, germs, and dry air, leading to discomfort such as nasal congestion, runny nose, itchy nose, and sneezing. In severe cases, it can even cause diseases like rhinitis and sinusitis. Nasal irrigation, as an effective nasal care method, helps remove foreign objects, secretions, and germs from the nasal cavity, reduces inflammation, relieves nasal discomfort, and maintains the physiological function of the nasal cavity.

[0003] Chinese patent CN220833601U discloses a nasal irrigator with a side-wall air inlet valve structure, including a bottle body and a bottle cap. The bottle cap is bent in two sections. An air inlet valve is provided on the side wall of the bottle body. The air inlet valve includes an air inlet rod, a bolt sleeve, a nut, a spring, a first sealing ring, and a second sealing ring. The bolt sleeve passes through the bottle body and is threadedly connected to the nut inside. A first sealing ring is provided between the nut and the bottle body. The bolt sleeve is through-type along the axis and has a stepped structure inside. When using this invention, the pressing distance of the index finger is very short, the force is very small, the feel is very comfortable, and the liquid is easy to dispense.

[0004] Existing nasal irrigators typically lack dedicated sterilization and drying devices for the irrigating head and reservoir. The irrigating head remains damp for extended periods, creating a breeding ground for bacteria and viruses. Even with regular manual cleaning, it is difficult to completely eliminate all microorganisms, increasing health risks. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that existing nasal irrigators are usually not equipped with a special disinfection and drying device for the irrigating head and the liquid storage tank. The irrigating head is in a damp state for a long time, which provides a breeding ground for bacteria and viruses. Even if the user cleans it manually every time, it is difficult to completely remove all microorganisms, which increases the health risk.

[0006] To address the aforementioned problems, this utility model provides a nasal irrigator, comprising a reservoir, an irrigation pipe at the upper end of the reservoir, a dispensing switch at the lower end of the reservoir, and a pump connected to the irrigation pipe at the inner end of the reservoir. The pump and the dispensing switch are electrically connected via wires. A circular outer plate is fixedly connected to the upper end of the reservoir, and a protective cover is threadedly connected to the upper end of the circular outer plate. A disinfection inner lamp ring is fixedly connected to the inner wall of the protective cover, and a breathable mesh is fixedly connected to the upper end of the protective cover. A drying pump located directly below the breathable mesh is threadedly connected to the upper inner wall of the protective cover. A bottom connecting piece is fixedly connected to the lower end of the drying pump, and a contact switch is fixedly connected to the lower end of the bottom connecting piece. Springs are symmetrically fixedly connected to the left and right sides of the lower end of the contact switch, and follower ring blocks are fixedly connected to the lower ends of the two springs, with the follower ring blocks located directly below the springs.

[0007] In the aforementioned nasal irrigator, after rinsing, the protective cover is placed on the liquid storage tank and rotated. During this process, the nasal irrigation pipe contacts the follower ring block below the drying pump, pushing the follower ring block upward and triggering the contact switch. This sends a signal to the controller to activate the protective cover function. Subsequently, the drying pump draws in the humid air inside the protective cover until it is dry, and then controls the disinfection inner ring of the ultraviolet LED lamp ring to start, disinfecting the relevant components and creating a hygienic environment.

[0008] As a further improvement of this application, the follower ring block is located directly above the nasal flushing pipe, and multiple individual assembly columns are fixedly connected to the upper end of the circular outer plate.

[0009] As a further improvement to this application, multiple individual assembly columns are located on the outside of the nasal flushing pipe, and an elastic connecting strip is fixedly connected to the outside of each individual assembly column.

[0010] As a further improvement of this application, a rubber replacement head is fixedly connected to the end of the elastic connecting strip away from the individual assembly column, and the rubber replacement head engages with the end of the nasal flushing pipe away from the liquid storage tank.

[0011] As another improvement of this application, the upper end of a single assembly column is fixedly connected with a protruding anti-loosening clamping ring, and the protruding anti-loosening clamping ring is connected to the rubber replacement head.

[0012] As a further improvement to this application, a counterweight base is fixedly connected to the lower end of the liquid storage tank, and a stabilizing suction cup is fixedly connected to the lower end of the counterweight base.

[0013] As a further improvement to this application, the liquid storage tank has a built-in controller, which is electrically connected to the sterilization inner lamp ring, the drying pump, and the spring via wires.

[0014] In summary, the nasal irrigator of this technical solution mainly consists of a storage tank and related components. The storage tank is used to store nasal irrigant. During use, the storage tank is held upside down and the tactile waterproof dispensing switch is pressed. The connected miniature diaphragm pump is activated, allowing the nasal irrigant to be sprayed out through the nasal irrigation tube for convenient nasal irrigation. After rinsing, the protective cover is closed and rotated. The nasal irrigation tube touches the following ring block below, compressing the spring and pushing the following ring block upward, triggering the normally open micro switch. The signal is transmitted to the controller, activating the protective cover function. A small centrifugal fan drying pump extracts the humid air and stops after the inside of the protective cover is dry. Then, the ultraviolet LED disinfection inner light ring is activated to disinfect the components above the storage tank, creating a hygienic environment and reducing the risk of cross-infection. The single mounting column on the circular outer plate of the storage tank is secured to multiple rubber replacement heads by an outwardly protruding anti-detachment locking ring, making it convenient for different family members to replace them as needed, improving the product's applicability and economy.

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] First implementation method:

[0025] Figure 2-6 A nasal irrigator is shown, comprising a reservoir 1, a nasal irrigation tube 2 at the upper end of the reservoir 1, a dispensing switch 19 at the lower end of the reservoir 1, a pump connected to the nasal irrigation tube 2 at the inner end of the reservoir 1, and an electrical connection between the pump and the dispensing switch 19 via a wire. A circular outer plate 3 is fixedly connected to the upper end of the reservoir 1, and a protective cover 8 is threadedly connected to the upper end of the circular outer plate 3. A disinfection inner lamp ring 16 is fixedly connected to the inner wall of the protective cover 8. The upper end of the protective cover 8 is fixedly connected to a breathable mesh 17. The upper inner wall of the protective cover 8 is threadedly connected to a drying pump 9 located directly below the breathable mesh 17. The lower end of the drying pump 9 is fixedly connected to a bottom connecting piece 10. The lower end of the bottom connecting piece 10 is fixedly connected to a contact switch 11. The lower ends of the contact switch 11 are symmetrically fixedly connected to springs 12 on the left and right sides. The lower ends of the two springs 12 are fixedly connected to follower ring blocks 13, which are located directly below the springs 12.

[0026] Figure 2-6 The following is shown: the follower ring block 13 is located directly above the nasal irrigation pipe 2. Multiple individual assembly columns 4 are fixedly connected to the upper end of the circular outer plate 3. The multiple individual assembly columns 4 are located on the outside of the nasal irrigation pipe 2. An elastic connecting band 5 is fixedly connected to the outside of the individual assembly column 4. A rubber replacement head 6 is fixedly connected to the end of the elastic connecting band 5 away from the individual assembly column 4. The rubber replacement head 6 is engaged with the end of the nasal irrigation pipe 2 away from the liquid storage tank 1. An outwardly protruding anti-detachment clamping ring 18 is fixedly connected to the upper end of the individual assembly column 4. The outwardly protruding anti-detachment clamping ring 18 is connected to the rubber replacement head 6. The liquid storage tank 1 has a built-in controller. The controller is electrically connected to the disinfection inner lamp ring 16, the drying pump 9, and the spring 12 through wires.

[0027] Figure 2-6As shown in this technical solution, the reservoir 1 plays a crucial role in storing the nasal rinse solution. Before use, the user needs to fill the reservoir 1 with an appropriate amount of nasal rinse solution. During use, simply hold the reservoir 1 upside down and press the touch-sensitive waterproof dispensing switch 19. The pump, a miniature diaphragm pump electrically connected to the dispensing switch 19 via a wire, will start, driving the nasal rinse solution in the reservoir 1 to be sprayed out through the nasal rinse tube 2, achieving convenient nasal rinsing and meeting the user's daily nasal cleaning needs. After rinsing, the user places the protective cap 8 over the reservoir 1 and rotates it to the appropriate position. During this process… The nasal irrigation pipe 2 contacts the follower ring block 13 below the drying pump 9, which is a small centrifugal fan. As the protective cover 8 rotates further, the follower ring block 13 is subjected to an upward pushing force, causing the spring 12 to compress. Its reaction force pushes the follower ring block 13 upward until it contacts the contact switch 11, which is a normally open micro switch. After the contact switch 11 is triggered, it sends a signal to the controller built into the liquid storage tank 1 to activate the function of the protective cover 8. After receiving the signal, the controller drives the drying pump 9 to draw the humid air above the liquid storage tank 1 inside the protective cover 8 to the outside through the ventilated mesh 17. Once the humidity inside the protective cover 8 has significantly decreased and reached a dry state, the controller stops the drying pump 9. Subsequently, the disinfection inner lamp ring 16 of the ultraviolet LED lamp ring is activated, emitting disinfecting light to irradiate and disinfect components above the liquid storage tank 1, such as the nasal irrigation pipe 2, effectively killing any bacteria, viruses, and other microorganisms that may be present. This creates a more hygienic environment for the next use, reduces the risk of cross-infection, and extends the product's lifespan. The circular outer plate 3 of the liquid storage tank 1 is equipped with multiple individual assembly pillars 4. Each individual assembly pillar 4 is tightly engaged with a rubber replacement head 6 by an outwardly protruding anti-detachment clamping ring 18. When different family members use the nasal irrigator, the required replacement rubber head 6 can be removed from the individual assembly column 4 and snapped onto the outside of the nasal irrigation tube 2, allowing the liquid reservoir 1 to flexibly adapt to the needs of different users. This ensures hygiene while improving the product's applicability and economy, and avoids the hygiene hazards caused by multiple people sharing the same nasal irrigator head. In terms of rinsing function, convenient nasal irrigation can be achieved through simple upside-down grip and pressing operation. In terms of protection and disinfection, the protective cover 8 integrates drying and disinfection functions, effectively maintaining the dryness and hygiene of the internal components. In terms of adaptability, multiple replaceable rubber heads 6 meet the needs of different family members.

[0028] Second implementation method:

[0029] Figure 1A nasal irrigator is shown. A counterweight base 14 is fixedly connected to the lower end of the liquid reservoir 1, and a stabilizing suction cup 15 is fixedly connected to the lower end of the counterweight base 14. At the lower end of the liquid reservoir 1, the counterweight base 14 increases the weight at the bottom, causing the overall center of gravity to shift downward. The stabilizing suction cup 15 can fit tightly against the placement surface. The combination of the two further enhances the placement stability and effectively prevents the nasal irrigator from tipping over during placement, avoiding problems such as liquid leakage or equipment damage caused by tipping. The design of the counterweight base 14 and the stabilizing suction cup 15 ensures that the nasal irrigator is placed stably, reducing potential problems caused by tipping.

[0030] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
