Background

Western medicine believes that when the cilia oscillation frequency of the respiratory tract is reduced by the induction factors of cold catching, rain catching, excessive fatigue and the like of a human body, viruses, bacteria and fungi which originally exist in the respiratory tract and invade from the outside can be rapidly propagated to cause cold. Inflammation of the nasopharynx is the main manifestation. The major common cold causing agents are rhinoviruses.

In prevention, the nose is washed away every morning and evening to wash away virus and harmful substances accumulated in the nasal cavity, so that the virus and the harmful substances are prevented from propagating in large quantities and invading human bodies. And simultaneously creates conditions for the recovery of damaged nasal tissues. The two components act together to improve the resistance of human body.

In treatment, the cold virus firstly proliferates in the epithelial cells of the nasal cavity in a large amount and then invades the human body. However, the mucus secreted by the nasal mucosa, known as a rhinorrhea, is a large quantity of mucus which continuously discharges the virus. Therefore, the nasal discharge and a large amount of viruses in the nasal discharge can be washed out by continuously cleaning the nasal cavity, the viruses are prevented from entering the human body again, and the number of the viruses invading the human body is greatly reduced.

Fig. 5 is a schematic illustration of a spray nasal irrigation device of an irrigation system, a schematic flow diagram of an irrigation system including a spray nasal irrigation device according to a first embodiment. The cleaning liquid system includes astorage space 11, a cleaningliquid 12, and afirst flow path 13. Thehousing 1 includes at least oneinsulating body 15 disposed in thestorage space 11. Theinsulating body 15 may be, for example, any structural part and/or structural member of thehousing 1 within thestorage space 11 thereof. Thepartition 15 is configured to separate and/or divide thestorage space 11 into thefirst flow path 13 and thesecond flow path 16.

As shown, thecleaning liquid 12 is arranged in thestorage space 11 of thehousing 1 and is guided out by thefluid 41 in thesecond flow path 16 at the upstream outlets 13 ', 16' by the upstream 23 of theflow control member 2 with the outflow opening 14 at the bottom of thefirst flow path 13. Thefirst flow path 13 and thesecond flow path 16 are each configured to contain afluid 41 for transporting thecleaning fluid 12. As shown in fig. 5, the spray nasal irrigation device comprises ahousing 1 and aflow control member 2. Thehousing 1 defines afirst flow path 13 and asecond flow path 16, thefirst flow path 13 and thesecond flow path 16 being separately spaced downstream of thehousing 1, thefirst flow path 13 and thesecond flow path 16 being spaced from and adjacent to each other at an upstream outlet 13 ', 16' of thehousing 1. Theflow control member 2 is disposed at the upstream outlets 13 ', 16' of the first andsecond flow paths 13, 16, the third andfourth flow paths 21, 22 of theflow control member 2 are spaced apart and adjacent downstream, the third andfourth flow paths 21, 22 are inupstream fluid communication 41, in other words, the third andfourth flow paths 21, 22 intersect at the upstream point 23, and the third andfourth flow paths 21, 22 intersect. A portion of theflow control member 2 defines a venturi structure in thethird flow path 21 at a location upstream 23 of the intersection of thethird flow path 21 and thefourth flow path 22. In other words, a portion of thethird flow path 21 and thefourth flow path 22 includes a converging portion having an inlet end 211 (having a first diameter) and an outlet end 212 (having a second diameter smaller than the first diameter).

Thehousing 1 of the spray nasal irrigation device is configured to accommodate at least a portion of theoutflow 14 portion of the cleansingliquid 12. In this way, theoutflow 14 portion of thewashing liquid 12 and thefluid 41 of thefirst flow path 13 are guided out at the upstream outlets 13 ', 16' by the upstream 23 of theflow control member 2. Thus, as described in more detail herein, theoutflow 14 from thewashing liquid 12 may be conveyed from the outletline output fluid 41 of theair pump 4 to theflow control member 2 via thefirst flow path 13. In addition, theair pump 4 determines the output parameters of the time curve of the outflow of the fluid 41 upstream of theflow control member 2, such as the injection pre-pressure, the injection frequency, the outflow interval ratio and the phase relationship between the outflow interval and the interval of the cleaningfluid 12, which can be individually adjusted or changed, so that theflow control member 2 can directly or intermittently output the spray.

Theflow control member 2 is disposed at a position upstream of thefirst flow path 13 and thesecond flow path 16. In other words, theflow control member 2 is disposed within the first andsecond flow paths 13, 16 at a position upstream of the outlets 13 ', 16' of the first andsecond flow paths 13, 16. The flow control means 2 is configured to restrict, control and/or regulate the flow of the cleaningliquid 12 within thefirst flow path 13. The flow control means 2 is an insert means defining upstream outlets 13 ', 16' through its first andsecond flow paths 13, 16.

Fig. 6 and 7 are cross-sectional views of aflow control member 2 according to an embodiment, theflow control member 2 including acover 2A and anozzle 2B. Theouter cover 2A includes a first end portion (i.e., aninlet end 211 portion of the fluid 41), a second end portion (i.e., anoutlet end 212 portion of the fluid 41), and an ejection portion 213 (i.e., a diverging portion of the third flow path 21). The first end portion of theouter lid 2A defines athird flow path 21. The first end portion of theouter lid 2A comprises a raisedregion 19 disposed at the upstream outlets 13 ', 16' of the first andsecond flow paths 13, 16. Thenozzle 2B is provided with an annular portion correspondingly engaging thesecond flow path 16 and a throughhole 26 passing through thethird flow path 21, thenozzle 2B is provided with afourth flow path 22 and athird flow path 21 formed together with thecover 2A, respectively, thefourth flow path 22 and thethird flow path 21 are correspondingly connected to the upstream outlets 16 ', 13' of thesecond flow path 16 and thefirst flow path 13, respectively, thefourth flow path 22 is communicated to thefirst flow path 13, and thethird flow path 21 is provided with a plurality of throughholes 26.

In use, thehousing 1 receives the cleansing liquid 12 from thestorage space 11 via the side opening 17 (as shown in fig. 4 and 8), theside opening 17 is sealed by theside cover 3, and the cleansingliquid 12 is sent to the spray nasal irrigation device via thefirst flow path 13 and anoutlet 14 portion of the cleansingliquid 12. Theoutlet end 212 of thethird flow path 21 of theflow control member 2 is afirst opening 24 which intersects thefourth flow path 22 as a second opening 25, wherein the opening diameter of thefirst opening 24 is larger than the opening diameter of the second opening 25, and thefirst opening 24 of theflow control member 2 is connected and communicated with the second opening 25. More specifically, the fluid 41 from thehousing 1 is injected into the second opening 25 for transport to the cleaningfluid 12 via thefourth flow path 22 when the flow rate of the fluid from thefirst opening 24 of theflow control member 2 increases and the pressure decreases through thefirst opening 24 of thethird flow path 21. In this embodiment, thehousing 1 may include asuction port 18 for controlling the flow of the fluid 41 into thethird flow path 21, and the flow rate of the fluid 41 in thethird flow path 21 is controlled by thesuction port 18 of thehousing 1. In other words, theflow control member 2 adjusts the ratio of thefluid 41 of the cleaningliquid 12 entering thesecond flow path 16 at thefirst flow path 13. For example, thefirst opening 24 of thethird flow path 21 having a large diameter may allowmore washing liquid 12 to be injected into the second opening 25 through thefourth flow path 22 than thefourth flow path 22 having a small diameter in theflow control member 2.

When the cleaningliquid 12 is directed through thefluid 41 of thethird flow path 21 and through thefirst opening 24 at the upstream 23, the local pressure of the fluid 41 in the portion of thefourth flow path 22 adjacent to thefirst opening 24 at the upstream 23 is reduced compared to the pressure of the fluid 41 in the remaining portion of thefourth flow path 22. In other words, a local low pressure zone and/or vacuum is created when the cleaning liquid 12 passes through thefirst opening 24 at the upstream 23 of thethird flow path 21. Thus, the vacuum causes the cleaningliquid 12 to be drawn from thefirst flow path 13 of thestorage space 11 into thefourth flow path 22. The cleaningliquid 12 flowing through thefourth flow path 22 is combined with the fluid 41 flowing through thethird flow path 21, and the second opening 25 of theflow control member 2 enables a spray cleaning operation to be performed on the throat, the nasal cavity, and the like, thereby achieving a deep cleaning and care effect. In this way, fluid 41 may be conveyed from thesecond flow path 16 of theair pump 4 to thethird flow path 21 of theflow control member 2 and adjacent to thefourth flow path 22 of the cleaningliquid 12 to prevent a break of the cleaningliquid 12.

Although the cleaningliquid 12 is illustrated as being disposed within thestorage space 11 of thehousing 1 in fig. 5, if more than two portions are used within thestorage space 11 of thehousing 1, the cleaningliquid 12 may be disposed within any of the formed portions. Although the cleaningliquid 12 is shown as being disposed within thestorage space 11, the cleaningliquid 12 may alternatively be disposed and secured outside thestorage space 11.

Although the flow control means 2 is shown and described above as being configured to be disposed at least in part of the upstream outlets 13 ', 16' of the first andsecond flow paths 13, 16 of thehousing 1. In other words, the upstream outlets 13 ', 16' of theflow control member 2 disposed in thefirst flow path 13 and thesecond flow path 16 of thehousing 1 may be directly coupled in any suitable manner. In other words, theflow control member 2 may be connected to the upstream outlets 13 ', 16' of the first andsecond flow paths 13, 16 of thehousing 1 without any intervening structures (e.g. without any hoses, clamps, fittings, etc.).

Although the third andfourth flow paths 21, 22 of the flow control means 2 are shown as converging from a first diameter to a second diameter smaller than the first diameter, in other embodiments the third andfourth flow paths 21, 22 may each comprise both converging and diverging portions. Thefourth flow path 22 of theflow control member 2 comprises a converging portion at upstream 23 and thethird flow path 21 comprises a converging portion and a diverging portion at upstream 23. In this way, as the fluid 41 flows through thethird flow path 21 and through the upstream 23, the local pressure of the fluid 41 within the portion of thefourth flow path 22 located at the upstream 23, the lowest pressure occurring substantially adjacent to the throat (i.e., the portion of the upstream 23 having the smallest diameter).

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
