Description

Technical Field

[0001] The utility model relates to the field of nasal irrigators, in particular to a filtering structure and a nasal irrigator connector. Background Art

[0002] Nasal irrigation is a treatment method for nasal diseases. Existing nasal irrigators mainly use water jets or water mist to rinse the nasal cavity. Existing nasal irrigators mainly include two parts: the irrigator body and the connector. Figure 4 The connector is provided with a flushing head 300 and a suction head 400. The flushing head 300 is used to spray liquid into the nasal cavity, and the suction head 400 is used to suck the waste liquid after flushing the nasal cavity. During the application of the existing product, users have continuously reported that when there are large secretion scabs in the nasal cavity, the inlet or pipeline of the suction head (silicone head) is blocked after being flushed out by the water flow, and it cannot be used normally; the reason for this situation is: the opening of the existing suction head is very small, and the corresponding pipelines and interfaces are also very small. The key is that the pipelines of the matching diaphragm pumps on the market are basically small-hole, so the solution of simply increasing the system pipeline is not feasible. In this case, choosing to retain the design standards of the original product and solving the pain point of large-sized scabs in the nose blocking the pipeline is a technical problem that technical personnel in this field urgently need to solve.

[0034] Example 1

[0035] The filtering structure provided in this embodiment is mainly used in nasal irrigators, especially installed in the suction head of the irrigator connector, for intercepting large-sized scabs carried in the nasal irrigating liquid to avoid blockage of the pipeline and affecting the nasal irrigator's suction function of the liquid.

[0036] like Figure 1 and Figure 2 As shown, the filter structure 100 includes a filter assembly, a flow guide tube 120 and a plurality of connectors 130;

[0037] The filter assembly uses a circular filter plate 110, which is provided with a plurality of filter holes 111 for passing liquid. The filter holes 111 play a role in the circulation of liquid and at the same time, the filter plate 110 plays a role in blocking large-sized scabs.

[0038] The diameter of the guide tube 120 is smaller than the diameter of the filter plate 110. One end of the guide tube 120 is connected to the filter plate 110 through at least one connector 130. In addition, there is a gap between the guide tube 120 and the filter plate 110 for liquid to pass through. The other end of the guide tube 120 is used to be inserted into the guide hole 210 of the nasal irrigator connector.

[0039] In addition, the filter assembly can also adopt another structural form:

[0040] like Figure 3 As shown, specifically: the filter assembly includes a filter screen 140 and an annular frame 150;

[0041] One end of the flow guide tube 120 is connected to one side of the annular frame 150 through at least one connector 130, and the filter screen 140 is connected to the other side of the annular frame 150 to filter the liquid through the plurality of filter holes on the filter screen 140. In addition, there is a gap between the filter screen 140 and the flow guide tube 120 for the liquid to pass through.

[0042] As a preferred embodiment, the wall of the guide tube 120 is provided with a guide groove 121 for passing liquid. When in use, the liquid entering the suction head 400 flows directly into the guide hole 210 of the connector base 200 through the guide groove 121.

[0043] As a preferred embodiment, multiple guide grooves 121 are provided and evenly distributed along the circumferential direction of the tube wall of the guide tube 120 , so that the liquid can evenly flow into the guide hole 210 of the joint base 200 through each guide groove 121 .

[0044] As a preferred embodiment, a plurality of connectors 130 are provided, and the plurality of connectors 130 are evenly distributed in the circumferential direction of the flow guide tube 120 and the filter assembly, so as to enhance the stability of the connection between the flow guide tube 120 and the filter assembly.

[0045] As a preferred embodiment, the connector 130 is configured as an L-shaped rod, one end of the L-shaped rod is connected to the end of the tube wall of the guide tube 120, and the other end of the L-shaped rod is connected to a position near the outer edge of the filter plate 110 or the annular frame 150. With this structural form of the connector 130, the L-shaped rod can be dispersed in the circumferential direction of the filter plate 110 or the annular frame 150 without interfering with the filter hole 111.

[0046] Using the filtration structure provided in this embodiment, the filter assembly is provided with a plurality of filter holes 111 for passing liquid; one end of the guide tube 120 is connected to the filter assembly via at least one connector 130, and a gap for passing liquid is provided between the guide tube 120 and the filter assembly. During use, the filter structure 100 can be placed inside the suction head 400, and the guide tube 120 can be directly inserted into the guide hole 210 of the nasal irrigator. After passing through the suction port, waste liquid passing through the nasal cavity is first filtered through the filter holes 111, blocking some large scabs in the nose, thereby preventing blockage of the suction head 400 pipeline.

[0047] Example 2

[0048] like Figure 5 and Figure 6 As shown, this embodiment provides a nasal irrigator connector, including a connector base 200, a rinsing head 300, a suction head 400 and the filter structure 100 in the above-mentioned embodiment 1;

[0049] The suction head 400 and the flushing head 300 are respectively connected to the connector base 200;

[0050] A guide hole 210 is provided in the connector base 200 and communicates with the suction head 400;

[0051] The filter structure 100 is located inside the suction head 400 , and in the filter structure 100 , the flow guide tube 120 is inserted into the flow guide hole 210 .

[0052] As a preferred embodiment, the suction head 400 can be made of silicone material, which is convenient for installing and disassembling the filter structure 100. At the same time, it can also fully surround the filter plate 110 in the circumferential direction so that the liquid can only flow through the filter holes 111.

[0053] As a preferred embodiment, the suction head 400 is spherical, and a waste liquid inlet 410 is provided at the end away from the connector base 200 for the passage of liquid.

[0054] As a preferred embodiment, the flushing head 300 is made of silicone material.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
