Summary of the invention

[0007] The purpose of the present invention is to provide a nasal irrigator with a water flow regulation function, so as to solve the problem proposed in the above background technology that during the operation, the water supply is mostly fixed, and the water supply cannot be conveniently and adaptively adjusted according to the nasal size of different patients, resulting in discomfort to some patients during the cleaning of the nasal cavity, and thus there are certain usage limitations.

[0008] To achieve the above object, the present invention provides the following technical solution: a nasal irrigator with a water flow regulating function, comprising an irrigator docking piece and a supply nozzle, wherein the input end of the irrigator docking piece and the water supply end of the irrigator are docked with each other, and the upper end of the irrigator docking piece is provided with a supply nozzle;

[0009] The outer side of the supply nozzle is bonded and connected with an external docking piece, the lower end of the flusher docking piece is threadedly connected with an auxiliary movable positioning piece, and a threaded structure is provided between the auxiliary movable positioning piece and the flusher docking piece, and an auxiliary guide structure is provided on the inner side of the flusher docking piece, and the positioning range of the external docking piece is controlled by the auxiliary guide structure;

[0011] Furthermore, the auxiliary guide structure is provided with a docking connector, and the docking connector is nested and docked on the inner side of the auxiliary movable positioning member. A preset accommodating groove is opened on the inner side of the flusher docking member, and the preset accommodating groove is nested and docked with the docking connector to form a sliding structure of the docking connector.

[0012] Furthermore, the upper end of the docking connector is fixedly connected with an abutting docking member, and the abutting docking member and the inner side of the preset receiving groove are butted against each other, the inner upper end of the preset receiving groove is adhesively connected with a docking support airbag, and the positions of the docking support airbag and the abutting docking member correspond to each other;

[0013] The outer side of the docking support airbag is penetrated and docked with a supply hose assembly, and the supply hose assembly passes through the inside of the flusher docking piece. The inner side of the external docking piece is bonded and connected with an inflation airbag assembly, and the ends of the inflation airbag assembly and the supply hose assembly are connected to each other.

[0014] Furthermore, the docking connector forms a nested structure along the inner side of the auxiliary movable positioning member, and the auxiliary movable positioning member pushes the resisting docking member through the docking connector to synchronously form a sliding structure along the inside of the flusher docking member, and the resisting docking member applies pressure to the contacting docking support airbag, so that the contacting docking support airbag is supplied with air to the inside of the expansion airbag assembly at the end through the supply hose assemblies that are docked with each other.

[0015] Furthermore, during the process of the docking support airbag being expanded under pressure, the supply hose assembly is used to apply pressure to the inside of the expansion airbag assembly, so that the expansion of the expansion airbag assembly pushes the external docking piece to deform.

[0016] Furthermore, the water flow self-regulating structure is provided with a docking traction rope, and the docking traction rope is docked at the inner wall of the external docking piece, and the docking traction rope passes through the inside of the flusher docking piece, the inner wall of the flusher docking piece is provided with a guide slot, and a docking movable rod is nested and installed inside the guide slot, and a preset magnet is fixedly connected to the lower end of the docking movable rod;

[0020] Furthermore, in the process of the docking movable rod driving the preset magnet part to move downward, the repulsive force and contact driving force between the same magnetic poles push the four sealing docking parts downward, and the sealing docking parts form an elastic support structure with the inner side of the flusher docking parts through the reset spring, which stably pushes the four sealing docking parts to move downward and unfold themselves, thereby cooperating with the self-positioning state of the external docking parts. During the working process, the water supply can be conveniently and adaptively adjusted according to the nasal cavity size of different patients.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The nasal irrigator with water flow regulation function is provided with an auxiliary guiding structure. After the supply nozzle is placed inside the user's nasal cavity, it is only necessary to rotate the auxiliary movable positioning member to push the inner docking connector and the abutting docking member to move inward synchronously, so as to apply pressure to the contacting docking support airbag, so that the air is supplied to the inside of the expansion airbag assembly at the end through the mutually docked supply hose assembly, so that the expansion airbag assembly expands and pushes the annular external docking member to deform to perform self-positioning processing on the inside of the patient's nasal cavity, and fill the gap between the inside of the nasal cavity and the supply nozzle, so as to avoid discomfort such as leakage during the irrigating process, thereby improving the practicality of the device;

[0024] Furthermore, since the docking movable rod and the preset magnet part at the lower end are an integrated structure, and the preset magnet part and the sealing docking part are positioned corresponding to each other, when the docking movable rod drives the preset magnet part to move downward, and the magnet block on the surface of the sealing docking part contacts the preset magnet part, the repulsive force and contact driving force between the same magnetic poles will stably push the four sealing docking parts downward to move and unfold themselves, thereby cooperating with the self-positioning state of the external docking part. During the operation, the water supply can be conveniently and adaptively adjusted according to the size of the nasal cavity of different patients. The larger the nasal cavity of the patient, the larger the range of the water supply passage, and vice versa. The smaller the nasal cavity, the smaller the water supply.

[0042] On the basis of the first embodiment, a water flow self-regulating structure is also disclosed, and its specific structure is as follows:
