Abstract
Description
Technical Field
[0001] This utility model relates to the field of swimming equipment, and more particularly to a swimming nose plug unit and a swimming nose plug. Background Technology
[0002] When swimming, people are prone to choking on water (water entering the nose), which is quite uncomfortable. In addition, because the disinfectants commonly used in swimming pools release chlorine, there may also be various impurities, bacteria and other pollutants in the water. Some people are allergic to these substances, which can easily trigger allergic rhinitis attacks, causing symptoms such as itchy nose, sneezing, and runny nose.
[0003] Currently, the main products on the market for preventing water from entering the nose are nose clips. However, prolonged pressure from nose clips on the nasal soft tissue and mucous membranes can lead to local congestion, swelling, and even damage, increasing the risk of bacterial infection; they also offer poor wearing comfort. In recent years, some nasal plugs have also appeared. However, these products simply block the nasal cavity, preventing both inhalation and exhalation, forcing the wearer to rely entirely on oral breathing. This conflicts with the "mouth-inhale-nose-exhale" breathing pattern commonly used in swimming, causing discomfort and breathing difficulties, and affecting the swimming experience. Utility Model Content

Each partition plate is evenly arranged on the periphery of the core column, and each partition plate is connected to the inner ring of the support cylinder. Every two adjacent partition plates form a flow hole between the core column and the support cylinder. The support column is arranged in the length extension direction of the core column.
[0022] The support cylinder is inserted into the stepped groove, and the support column is supported at the center of the elastic sealing sheet.
[0023] Preferably, a first annular groove and a second annular groove are formed around the periphery of the body;

[0049] Figure 1 and Figure 2 The illustration shows a swimming nose plug unit 10 in some embodiments of the present invention, which is used to allow unidirectional flow of fluid. The fluid can be a gas, liquid, or gas-liquid mixture, depending on the application environment, but regardless of the fluid, unidirectional flow can be achieved.
[0050] like Figures 1 to 4 As shown, the swimming nasal plug unit 10 includes a body 1 and an elastic sealing sheet 2, which is disposed within the body 1. It should be noted that the body 1 provides fluid flow, and the elastic sealing sheet 2 can achieve unidirectional fluid flow within the body 1 through deformation.
[0051] like Figures 3 to 6As shown, the main body 1 has a first channel 122 and a second channel 112. The second channel 112 is provided with a sealing ring rib 113 at the end near the first channel 122, and the first channel 122 is provided with a support column 123 at the end near the second channel 112.
[0052] The elastic sealing sheet 2 is disposed between the first channel 122 and the second channel 112. The elastic sealing sheet 2 has a first surface 21 and a second surface 22 opposite to each other. The support column 123 is supported on the first surface 21, and the sealing ring rib 113 is supported on the second surface 22. The elastic sealing sheet 2 covers the sealing ring rib 113.
[0053] Please refer to the following: Figure 7 As the fluid flows from the first channel 122 to the second channel 112 and deforms against the elastic sealing sheet 2, the elastic sealing sheet 2 remains firmly sealed against the sealing ring rib 113. Please refer to the following: Figure 8 When the fluid flows from the second channel 112 to the first channel 122, the elastic sealing sheet 2 is held by the fluid and deforms, detaches from the sealing ring rib 113 and abuts against the support column 123, so that the fluid can further flow into the first channel 122.
[0054] Understandably, both the first channel 122 and the second channel 112 are used to guide the flow of fluid. If the body 1 is placed inside the nasal cavity, the outer periphery of the body 1 will be in sealed contact with the nasal cavity, so that the fluid can only flow along the first channel 122 and the second channel 112.
[0055] The function of the sealing ring rib 113 is to form an annular sealing contact with the second surface 22 of the elastic sealing sheet 2, blocking fluid penetration through surface contact and ensuring the integrity of the sealing interface under reverse pressure. The function of the support column 123 is to provide a constant pre-pressure to the first surface 21 of the elastic sealing sheet 2, forcing the elastic sealing sheet 2 to continuously press the sealing ring rib 113 in its natural state, achieving a pre-sealing state under zero pressure difference conditions.
[0056] The elastic sealing sheet 2 can respond to changes in fluid pressure through its own elastic deformation. Specifically:
[0057] When fluid flows from the first channel 122 to the second channel 112, the elastic sealing sheet 2 is held in place by the fluid but remains tightly pressed against the sealing ring rib 113, maintaining a forced locking state. It should be noted that during this deformation process, even if the elastic sealing sheet 2 separates from the support column 123 and the contact position between the elastic sealing sheet 2 and the sealing ring rib 113 changes continuously, the elastic sealing sheet 2 will always remain tightly pressed against the surface of the sealing ring rib 113 under the pressure of the fluid. Thus, a reliable and stable seal can always be maintained between the elastic sealing sheet 2 and the sealing ring rib 113, effectively blocking the fluid.
[0058] When fluid flows from the second channel 112 to the first channel 122, the elastic sealing sheet 2 disengages from the sealing ring rib 113, but the portion in contact with the support column 123 remains in a stable position. Thus, fluid can flow through the gap between the elastic sealing sheet 2 and the sealing ring rib 113, thereby achieving fluid conduction in that direction.
[0059] The function of the first surface 21 is to bear the supporting force of the support column 123, converting the mechanical support into a sealing preload force. That is, in the natural state without fluid flow, the support column 123 will hold the elastic sealing sheet 2 against the sealing ring rib 113. The function of the second surface 22 is to form a dynamic sealing interface with the sealing ring rib 113, and to adaptively adjust the sealing contact area through deformation.
[0060] In some embodiments of the swimming nasal plug unit 10, at least a portion of the support post 123 passes through the sealing ring rib 113.
[0061] Understandably, the support column 123 can be configured such that a portion of it passes through the sealing ring rib 113. In this way, since the support column 123 is always pressed against the first surface 21 of the elastic sealing sheet 2, the force exerted by the support column 123 on the elastic sealing sheet 2 is greatly increased, thereby improving the tightness of the fit between the second surface 22 and the sealing ring rib 113, and further enhancing the barrier effect against fluid.
[0062] like Figure 2 and Figure 8 As shown, in some embodiments of the swimming nasal plug unit 10, the distance between the sealing ring rib and the support column 123 in the thickness direction of the elastic sealing sheet 2 is set to D2, where D2 = 0.
[0063] Understandably, the gap D2 between the sealing ring rib 113 and the support column 123 is 0, which will keep the elastic sealing sheet 2 located between the sealing ring rib and the support column 123 under pressure. That is, the elastic sealing sheet 2 is held tightly against the sealing ring rib 113 by the support column 123.
[0064] Specifically, the elastic sealing sheet 2 will adapt to the zero-gap (D2=0) state through its own elasticity to maintain the pre-tight sealing force. The zero-gap design optimizes the static sealing effect, reduces the probability of fluid leakage in non-working conditions, simplifies assembly tolerance requirements, and improves product consistency and durability.
[0065] like Figure 2 and Figure 8 As shown, in some embodiments of the swimming nasal plug unit 10, the thickness of the elastic sealing sheet 2 is set to D1. Along the thickness direction of the elastic sealing sheet 2, the distance between the sealing ring rib and the support column 123 is set to D2. Wherein, D2 ≤ D1, and D2 > 0.
[0066] Understandably, the function of the spacing D2 between the sealing ring rib 113 and the support column 123 is to define the pre-sealing gap, where D2≤D1 and D2>0, which can ensure that the elastic sealing sheet 2 can bend appropriately without being excessively squeezed when deformed.
[0067] It should be noted that in this embodiment, the deformation freedom and sealing strength of the elastic sealing sheet 2 are balanced by the dimensional relationship between D1 and D2, ensuring low resistance conduction of forward flow and efficient blocking of reverse flow, thereby improving the product's adaptability and energy efficiency in dynamic fluid environments.
[0068] like Figures 3 to 5 As shown, in some embodiments of the swimming nasal plug unit 10, a limiting portion 115 is provided within the second channel 112. Please refer to further details. Figure 7 When the elastic sealing sheet 2 deforms and penetrates into the second channel 112, it will abut against the limiting part 115; when the elastic sealing sheet 2 abuts against the limiting part 115, the elastic sealing sheet 2 seals against the sealing ring rib 113.
[0069] Understandably, the function of the limiting part 115 is to limit the maximum deformation of the elastic sealing sheet 2 under fluid pressure by rigidly blocking it, so as to prevent excessive deformation from causing seal failure or structural damage.
[0070] It should be noted that when the fluid flows from the first channel 122 to the second channel 112, the fluid will push the elastic sealing sheet 2 to deform and detach from the support column, and further deform to press against the limiting part 115. In this way, the deformation of the elastic sealing sheet 2 is constrained by the limiting part 115, ensuring that it remains in contact with the sealing ring rib 113. This prevents excessive deformation that could damage the elastic sealing sheet 2, and also prevents the elastic sealing sheet 2 from being completely pushed into the second channel 112.
[0071] like Figures 3 to 6 As shown, in some embodiments of the swimming nasal plug unit 10, the body 1 includes a front shell 11 and a rear shell 12.
[0072] A flow groove 111 is provided on the front shell 11, and a second channel 112 is provided at the bottom of the flow groove 111. A sealing ring rib 113 is located at the bottom of the flow groove 111 and surrounds the end of the second channel. A support column 123 is provided on the rear shell 12, and at least one flow hole 121 is provided around the support column 123.
[0073] The elastic sealing sheet 2 is disposed in the flow groove 111, the rear shell 12 is inserted into the flow groove 111, the support column 123 is inserted into the flow groove 111 and abuts against the elastic sealing sheet 2, and each flow hole 121 is connected to the flow groove 111 to form a second channel 112.
[0074] Understandably, the flow channel 111 provides a cavity space for fluid flow and also guides the installation and deformation of the elastic sealing plate 2. The second channel 112 communicates with the flow hole 121 through the flow channel 111. The flow hole 121 is used for fluid to pass through and flow.
[0075] The number of flow holes 121 can be configured to be multiple, and the multiple flow holes 121 are configured to be evenly distributed around the support column 123, thereby uniformly diffusing and guiding the fluid in the second channel 112 and reducing flow resistance.
[0076] The rear shell 12 is assembled with the front shell 11 by inserting a flow groove 111. This mechanical insertion method enables the front shell 11 and the rear shell 12 to be quickly positioned and fixed, simplifying the assembly process and improving the product assembly production efficiency. During the assembly process, the support column 123 will be inserted into the flow groove 111 under the drive of the rear shell 12 and further abut against the elastic sealing sheet 2.
[0077] It should be noted that in this embodiment, the separate front shell 11 and rear shell 12 optimize manufacturing and assembly efficiency, while the plug-in mating method ensures that the support column 123 and the sealing ring rib 113 are in the correct relative position, thus guaranteeing the product's sealing performance.
[0078] Furthermore, in some embodiments, the front shell 11 and the rear shell 12 can be connected by welding, fusion, clamping, bonding or other means; of course, they can also be configured to be made together by integral molding.
[0079] like Figure 4 and Figure 5 As shown, in some embodiments of the swimming nasal plug unit 10, a stepped groove 114 is provided on the wall of the flow channel 111;
[0080] Please see Figures 3 to 5 The rear shell 12 includes a core column 124, a support cylinder 125 and several partition plates 126. The support cylinder 125 is sleeved on the outside of the core column 124. Each partition plate 126 is evenly arranged on the periphery of the core column 124 and each partition plate 126 is connected to the inner ring of the support cylinder 125. Each pair of adjacent partition plates encloses a flow hole 121 between the core column 124 and the support cylinder 125. The support column 123 is arranged in the length extension direction of the core column 124.
[0081] The support cylinder 125 is inserted into the stepped groove 114, and the support column 123 is supported on the center of the elastic sealing sheet 2.
[0082] Understandably, the stepped groove 114 provides a mechanical positioning reference, ensuring precise alignment of the support cylinder 125 when the rear shell 12 is inserted, reducing sealing deviations caused by assembly tolerances. The core column 124, as the base of the support column 123, transmits preload to the center of the elastic sealing sheet 2, maintaining uniform sealing pressure. The support cylinder 125 is inserted into the stepped groove 114, thereby defining the relative position of the rear shell 12 and the front shell 11, minimizing assembly tolerances and ensuring product sealing. The partition plate 126 divides the annular space between the core column 124 and the support cylinder 125 into multiple flow holes 121, guiding fluid dispersion, reducing flow resistance, and avoiding turbulence. Simultaneously, the multiple partition plates 126 can support the core column 124 from multiple different angles, thus stably supporting the support column 123.
[0083] like Figures 3 to 5 As shown, in some embodiments of the swimming nasal plug unit 10, a first annular groove 13 and a second annular groove 14 are provided around the periphery of the body 1.
[0084] like Figure 1 and Figure 2 As shown, the swimming nasal plug unit 10 also includes a front sealing cover 3 and a rear sealing cover 4. (As...) Figures 3 to 5 The front sealing cover 3 is fitted inside the first annular groove 13, and the rear sealing cover 4 is fitted inside the second annular groove 14; a front sealing arc surface 31 is provided outside the front sealing cover 3, and a first rib 41 and a second rib 42 are provided on the outer periphery of the rear sealing cover 4, with the first rib 41 and the second rib 42 spaced apart.
[0085] The front sealing arc surface 31 is used to abut against the inner wall of the nasal cavity, and the first rib 41 and the second rib 42 are both used to abut against the inner wall of the nasal cavity.
[0086] Understandably, the first annular groove 13 provides an insertion position for the front sealing cover 3, and the second annular groove 14 provides an insertion position for the rear sealing cover 4, thereby preventing the front sealing cover 3 and the rear sealing cover 4 from falling off and ensuring the seal between the two sealing covers and the nasal cavity wall. Furthermore, the front and rear sealing covers can seal at two different depths within the nasal cavity. The front sealing arc surface 31 can adapt to the curvature of the nasal cavity wall, dispersing pressure through surface contact and avoiding discomfort caused by localized pressure. The arrangement of the first rib 41 and the second rib 42 forms a double-stage seal.
[0087] The beginning of the first annular groove 13 and the second annular groove 14 allows users to assemble front sealing covers 3 and rear sealing covers 4 of different sizes according to their individual nasal cavity size and nasal cavity contour, saving users the cost of purchasing swimming nasal plugs of different sizes. At the same time, it also allows for quick replacement of the front sealing covers 3 and rear sealing covers 4 that have failed, reducing the cost of use and improving the convenience of use.
[0088] like Figure 5 As shown, in some embodiments of the swimming nasal plug unit 10, the radius of the elastic sealing sheet 2 is set to R1, and the radius of the flow groove 111 is set to R2. Wherein, 0mm < R2 - R1 < 2mm.
[0089] Understandably, R2-R1>0mm ensures that a gap is maintained between the elastic sealing sheet 2 and the inner wall of the flow channel 111, avoiding frictional loss in the non-deformation state, and providing a certain deformation space for the elastic sealing sheet 2 to prevent the elastic sealing sheet 2 from getting stuck on the channel wall of the flow channel 111.
[0090] If R2-R1 < 2mm, the gap tolerance can be limited to prevent the elastic sealing sheet 2 from shifting excessively and failing to fully cover the sealing ring rib 113, thus ensuring the sealing performance of the elastic sealing sheet 2 for the second channel.
[0091] It should be noted that, through the present embodiment, the elastic sealing sheet 2 maintains precise alignment with the sealing ring rib 113 during deformation, preventing localized leakage caused by radial misalignment. Simultaneously, it reduces forward fluid flow resistance, improves exhalation efficiency, and maintains reliable reverse closure.
[0092] In some embodiments of the swimming nose plug unit 10, the surface of the sealing ring rib 113 is an arc surface, and the elastic sealing sheet 2 is movably supported against the arc surface.
[0093] Understandably, by using a rounded surface, the elastic sealing sheet 2 can maintain line contact with the sealing ring rib 113, thus ensuring a more reliable sealing effect. Compared to structures with sharp edges, the rounded surface used in this embodiment ensures that the elastic sealing sheet 2 has a sufficiently tight contact at all contact points, guaranteeing a reliable seal even if the elastic sealing sheet has varying degrees of local deformation.
[0094] Figure 9 and Figure 10 The present invention illustrates a swimming nose plug 20 in some embodiments, which includes two swimming nose plug units 10 and a connecting rope 30, the two swimming nose plug units 10 being connected by the connecting rope 30.
[0095] Understandably, the two swimming nasal plug units 10 act independently in different nasal cavities, achieving synchronized unidirectional exhalation. The connecting rope 30 serves to connect the two swimming nasal plug units 10, maintaining their relative positional stability and preventing the loss of one unit.
[0096] The following are the beneficial effects of implementing this utility model:
[0097] This utility model relates to a swimming nasal plug unit and a swimming nasal plug, the swimming nasal plug including the swimming nasal plug unit. In the swimming nasal plug unit, by setting an elastic sealing sheet, a sealing ring rib and a support column in a synergistic sealing structure, the elastic sealing sheet is always held tightly against the sealing ring rib by the support column in its natural state, forming a pre-sealed state, thereby achieving an automatic sealing effect against the fluid in the non-exhalation state, so that the product can achieve a reliable and stable seal without the need for fluid to push.
[0098] Secondly, when the fluid flows from the first channel to the second channel, the elastic sealing sheet always seals against the sealing ring rib, realizing a forced locking function in a certain direction, ensuring that the fluid can only flow unidirectionally from the second channel to the first channel (exhalation direction), while the reverse flow (inhalation direction) is completely blocked, so that the product can be used exclusively for exhalation scenarios.
