Description

Technical Field

[0001] This utility model relates to the field of nasal irrigator technology, and in particular to a nasal irrigator. Background Technology

[0002] A nasal irrigator is a medical or household tool used to clean the nasal cavity. It uses a gentle saline solution to rinse the nasal passages, helping to remove secretions, allergens (such as pollen and dust), germs, inflammatory substances, or other foreign objects. It is commonly used to relieve symptoms such as nasal congestion, allergies, colds, and sinusitis, or as part of daily nasal care. Specifically, a nasal irrigator can be used to clean the nasal cavity, flushing out mucus, dust, or allergens, reducing the residue of viruses and bacteria in the nasal cavity, thinning nasal secretions, relieving sinus pressure or nasal congestion, and can also be used as an adjunct treatment for allergic rhinitis, sinusitis, postoperative care, or during the recovery period from a cold. Nasal irrigators generally consist of a container holding nasal irrigation solution. Common types include squeeze-type nasal irrigators, pot-type nasal irrigators, and electric nasal irrigators.

[0003] Existing nasal irrigators generally consist of multiple structural components. Chinese patent CN222488089U discloses a nasal irrigator comprising: a cup holder with an air inlet and an air outlet communicating with the air inlet; a sliding switch assembly mounted on the cup holder; and multiple drain ports disposed on the cup holder and / or the sliding switch assembly. The sliding switch assembly includes: a sliding switch; a sliding switch bracket supporting and linked to the sliding switch; and a valve plate mounted on and linked to the sliding switch bracket. The valve plate moves under the control of the sliding switch assembly to seal or open the multiple drain ports, thereby adjusting the spray rate of the nasal irrigator. This allows the spray rate to be adjusted according to the user's needs without the need for electricity, thus improving the convenience of using the nasal irrigator. However, the aforementioned nasal irrigators are complex in structure, installation, and operation, resulting in insufficient ease of use. Utility Model Content

[0030] Please see Figure 1 This utility model discloses a nasal irrigator 1, which includes a nasal solution tank 10, a waste liquid tank 20, a nozzle 30, and a dust cover 40 connected in sequence. The nasal irrigator 1 also includes a spray structure 50, with the input end of the spray structure 50 disposed in the nasal solution tank 10 and the output end of the spray structure 50 extending to the nozzle 30 via the waste liquid tank 20. The nasal solution tank 10 is used to store the nasal solution. The waste liquid tank 20 is connected to the top of the nasal solution tank 10 to collect the waste liquid that flows back during the nasal irrigation process. The nozzle 30 is connected to the top of the waste liquid tank 20 and is provided with an output structure 31 and a return structure 32. The output structure 31 extends away from the waste liquid tank 20, and the return structure 32 is connected to the waste liquid tank 20. Specifically, the spray structure 50 includes an air supply pipe 51 and a liquid supply pipe 52. The air supply pipe 51 is located in the washing liquid tank 10, with its input end located outside the washing liquid tank 10 and its output end sequentially passing through the washing liquid tank 10 and the waste liquid tank 20, extending to the nozzle 30. The liquid supply pipe 52 is located in the waste liquid tank 20, and is sleeved outside the air supply pipe 51, with its input end located inside the washing liquid tank 10. The output end of the liquid delivery pipe 52 extends to the nozzle 30 in conjunction with the air delivery pipe 51. Based on this, a sandwich structure is formed between the liquid delivery pipe 52 and the air delivery pipe 51. When the air delivery pipe 51 outputs a high-speed airflow, a negative pressure is formed inside the sandwich between the air delivery pipe 51 and the liquid delivery pipe 52. The washing liquid inside the washing liquid chamber 10 is transported along the input end of the liquid delivery pipe 52 to the output end of the liquid delivery pipe 52, and then atomized under the action of the airflow and output by the nozzle 30 to complete the nasal rinsing process. The nasal irrigator 1 of this invention is installed and used by connecting the various components in a nested manner, making the nasal irrigator 1 easy to install, disassemble, and clean, effectively improving the ease of use of the nasal irrigator 1. The air delivery pipe 51 and the liquid delivery pipe 52 are respectively integrated into the washing liquid chamber 10 and the waste liquid chamber 20, which further simplifies the structure of the nasal irrigator 1, improves installation convenience, and also enhances the stability of the air delivery pipe 51 and the liquid delivery pipe 52, thereby ensuring the stability and controllability of the washing liquid output by the spray structure 50.

[0031] Furthermore, the inlet of the air supply pipe 51 extends from the bottom wall of the wash solution chamber 10 to the outside of the wash solution chamber 10. Based on this, an exhaust pipe 511 is provided on the side wall of the inlet of the air supply pipe 51. One end of the exhaust pipe 511 is connected to the air supply pipe 51, and the other end of the exhaust pipe 511 is connected to the outside of the wash solution chamber 10. Thus, the airflow entering through the air supply pipe 51 can be output through the outlet of the air supply pipe 51 and the exhaust pipe 511 respectively. When the exhaust pipe 511 is closed, the gas flow rate at the outlet of the air supply pipe 51 is at its highest. When the exhaust pipe 511 is open, part of the airflow is output through the exhaust pipe 511, thereby reducing the gas flow rate at the outlet of the air supply pipe 51, thereby realizing the function of adjusting the washing solution atomization and output efficiency of the nasal irrigator 1.

[0032] Furthermore, the output end of the exhaust pipe 511 extends along the bottom wall of the washing liquid tank 10 to the outside of the side wall of the washing liquid tank 10; based on this, the washing liquid tank 10 is provided with a sealing member 11 corresponding to the output end of the exhaust pipe 511. The sealing member 11 is movably connected to the side wall of the washing liquid tank 10 in cooperation with the output end of the exhaust pipe 511. By driving the sealing member 11 to abut against the output end of the exhaust pipe 511, the exhaust pipe 511 can be sealed, so that the airflow in the air supply pipe 51 flows out from the output end of the air supply pipe 51.

[0033] Specifically, in one embodiment, the outer surface of the side wall of the washing liquid tank 10 is provided with a mounting part 12 corresponding to the closure 11. The closure 11 is fitted into the mounting part 12 to ensure the installation stability of the closure 11. In order to further improve the installation stability of the closure 11, the closure 11 is provided with two connecting posts 111. The closure 11 is connected to the side wall of the washing liquid tank 10 through the two connecting posts 111.

[0034] Specifically, in one embodiment, the closure 11 is made of an elastic material to improve the sealing performance of the closure 11 on the output end of the exhaust pipe 511.

[0035] Specifically, in one embodiment, the mounting part 12 is provided with an exhaust hole a, which extends through the surface of the mounting part 12 to the inner bottom of the washing liquid tank 10, so that when the exhaust pipe 511 is in the open state, it can be connected to the external environment through the exhaust hole a, thereby preventing the airflow discharged from the exhaust pipe 511 from being sprayed out from the outside of the washing liquid tank 10 and affecting the user experience.

[0036] Furthermore, the reflux structure 32 is provided with a plurality of reflux holes b, which are arranged circumferentially along the edge of the reflux structure 32. The reflux structure 32 is connected to the waste liquid tank 20 through the plurality of reflux holes b to realize the reflux collection of washing liquid.

[0037] Furthermore, the reflux structure 32 is also provided with a hollow connecting part 321. The connecting part 321 is located at the center of the reflux structure 32, corresponding to the spray structure 50. The output structure 31 is sleeved on the connecting part 321. Thus, the washing liquid output by the spray structure 50 is output sequentially through the connecting part 321 and the output structure 31.

[0038] Furthermore, in one embodiment, the bottom of the nasal irrigator 10 extends further to the bottom side to form a support structure 13. In order to further improve the aesthetics of the nasal irrigator 1, in another embodiment, the support structure 13 is designed as a double-legged shape.

[0039] Furthermore, in one embodiment, the outer wall of the waste liquid tank 20 is provided with a plurality of reinforcing ribs 21, which are arranged circumferentially along the outer wall of the waste liquid tank 20. This not only improves the structural strength of the waste liquid tank 20, but also improves the anti-slip performance of the outer wall of the waste liquid tank 20 and enhances the user experience.

[0040] In summary, the nasal irrigator disclosed in this utility model has a nasal wash solution compartment for storing nasal wash solution; a waste liquid compartment is connected to the top of the nasal wash solution compartment to collect waste liquid that flows back during nasal irrigation; a nozzle is connected to the top of the waste liquid compartment, and the nozzle has an output structure and a return structure. The output structure extends away from the waste liquid compartment, and the return structure connects to the waste liquid compartment. Specifically, the spray structure includes an air delivery pipe and a liquid delivery pipe. The air delivery pipe is located in the nasal wash solution compartment; the liquid delivery pipe is located in the waste liquid compartment, and the liquid delivery pipe is sleeved outside the air delivery pipe. Based on this, a sandwich structure is formed between the liquid delivery pipe and the air delivery pipe. The nasal irrigator of this invention is installed and used by connecting the various components in an interlocking manner, which makes the nasal irrigator easy to install, disassemble and clean, and can effectively improve the convenience of use. The air supply pipe and the liquid supply pipe are integrated into the washing liquid tank and the waste liquid tank respectively, which can further simplify the structure of the nasal irrigator and improve the convenience of installation. At the same time, it can also enhance the stability of the air supply pipe and the liquid supply pipe, thereby ensuring the stability and controllability of the washing liquid output of the spray structure.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
