Technical Field

[0001] The utility model relates to the technical field of swimming equipment design, in particular to a nasal plug. Background Art

[0002] At present, products on the market usually include a nose strap (worn outside the nose to cover the nostrils, but water can still enter) and a nasal plug (with a simple structure and a hollow middle).

[0003] As disclosed in the invention patent with the publication number CN106422218A and the name of a nasal plug for swimming, the swimming nasal plug is composed of 2 plug bodies and 1 connecting body. During swimming, the 2 plug bodies can be respectively placed inside the left and right nasal cavities of the swimmer to prevent water from entering the nasal cavity.

[0004] In actual use, when using the above-mentioned nose strap type nasal plug, it is very easy for water to enter the nasal cavity under the action of movements in the water, and it is easy to fall off during swimming. When using the above-mentioned clamping type nasal plug, the nasal plug will collapse and deform after being worn for a long time, and the nasal plug will squeeze and rub the inside of the nasal cavity for a long time, which may cause the nasal mucosa to turn red, swell and cause pain.

[0036] Embodiment:

[0037] Referring to Figures 1 - 5 , this device is a nasal plug, including a plug body 1, the plug body 1 is used to be inserted into the nasal cavity, a through ventilation channel 2 is opened in the plug body 1 along the direction of its insertion into the nasal cavity, the plug body 1 includes an air inlet 3 and an air outlet 4 at both ends of the ventilation channel 2, the ventilation channel 2 is in a shape that is wide in the middle and narrow at both ends, the diameters of both the air inlet 3 and the air outlet 4 are smaller than the diameter of the outer body part 7, and the material of the plug body 1 is made of silica gel or rubber. A plurality of umbrella-shaped blocking colloids 5 are provided on the outer circumferential surface of the plug body 1 along its length direction, the blocking colloids 5 are used to fit with the inner wall of the nasal cavity, and the diameters of the plurality of blocking colloids 5 are larger at the position closer to the air outlet 4, so that the plug body 1 can be relatively fixed in the nasal cavity effectively. A pull tab 6 is provided on the plug body 1 and around the air outlet 4, this kind of pull tab 6 is used to facilitate the removal of the plug body 1 from the nasal cavity when not in use, preferably two such pull tabs 6 are provided, and the shape of the pull tab 6 is fish-tail-shaped, the width of the end closer to the air outlet 4 is smaller, and the width extending towards the outside of the nasal cavity is larger.

[0038] As Figure 2 shown, it further includes an exhalation component, the exhalation component is arranged in the ventilation channel 2, and the exhalation component is used for discharging the gas in the human body and preventing water from being inhaled into the nasal cavity. The exhalation component includes an outer body part 7, a sealing member and an adjusting member arranged in the outer body part 7, the outer body part 7 is made of 304 stainless steel and is in an overall cylindrical barrel shape, the outer body part 7 and the ventilation channel 2 are sealed, the air inlet 3 and the air outlet 4 of the ventilation channel 2 are conducted through the internal space of the outer body part 7, the sealing member is used to block the ventilation channel 2, as Figure 2 and Figure 4 shown, the sealing member includes an annular stop block 8 and a sealing rod 9, the stop block 8 is arranged on the inner wall of the outer body part 7, a sealing head 10 is arranged at the end of the sealing rod 9, the sealing head 10 is located at one end of the stop block 8 away from the air inlet 3, the sealing head 10 is used to slidably seal and abut against the side wall of the stop block 8, an annular sealing groove 11 is opened on the sealing head 10, and a sealing ring 12 is arranged in the sealing groove 11, and the sealing ring 12 is used to slidably seal and abut against one end of the stop block 8 away from the air inlet 3.

[0039] AsFigure 2 and Figure 3 As shown, the adjusting member is used to cooperate with the sealing member to further control the on-off of the fluid in the air passage 2. The adjusting member includes a pressing plate 13 and a spring 14. The pressing plate 13 is arranged in the outer body member 7 and moves along the length direction of the outer body member 7. One end of the sealing rod 9 away from the sealing head 10 slides through the pressing plate 13. When the pressing plate 13 is on the side away from the air inlet 3, the spring 14 is sleeved on the sealing rod 9 and both ends of the spring 14 are abutted or fixedly connected to the sealing head 10 and the pressing plate 13 respectively. At this time, the continuous sealing abutment between the sealing head 10 and the stop block 8 is realized by relying on the resilience of the spring 14. It is worth mentioning that when the pressing plate 13 is arranged on the side away from the air outlet 4, the spring 14 is sleeved on the sealing rod 9 and both ends of the spring 14 are fixedly connected to the sealing head 10 and the pressing plate 13 respectively. At this time, the continuous sealing abutment between the sealing head 10 and the stop block 8 is realized by relying on the pulling force of the spring 14. Both methods can achieve the function of exhaling and preventing water from entering the nasal cavity. Among them, the first method of realizing the continuous sealing abutment between the sealing head 10 and the stop block 8 by the resilience of the spring 14 is preferred.

[0040] As Figure 5 shown, a threaded groove 15 is provided on the inner wall of the outer body member 7, and an external thread 16 is provided on the side wall of the pressing plate 13. The pressing plate 13 is threadedly connected to the outer body member 7 through the cooperation of the external thread 16 and the threaded groove 15 and moves along the length direction of the outer body member 7. In this way, when in use, the pressing plate 13 can be adjusted by inserting an external tweezer into the air outlet 4 and rotating the pressing plate 13, so as to realize the movement adjustment of the pressing plate 13 in the outer body member 7, and the extrusion degree of the spring 14 can be effectively adjusted according to the exhalation force of different users.

[0041] Working principle:

[0042] When in use, first insert the plug body 1 into the nasal cavity, and keep the plug body 1 stable in the nasal cavity through a plurality of blocking colloids 5 on the outer wall of the plug body 1. When a person exhales, the sealing rod 9 slides on the pressing plate 13 due to the air pressure. At this time, a gap will be generated between the sealing head 10 at the end of the sealing rod 9 and the stop block 8, and the gas will be discharged from between them to the outside of the nasal cavity. Due to the action of the spring 14, when the person stops exhaling, the sealing head 10 will quickly rebound and re-seal and abut against the stop block 8 to prevent external water from entering the nasal cavity. This device provides the ability for swimmers to exhale conveniently and can improve the swimming experience of the person.
