Description

Technical Field

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

[0002] Diving is a popular underwater sport loved by the public. Among them, ear pressure equalization is a skill that divers must master. As the water pressure increases with the depth of the dive, it puts pressure on the diver's eardrum. Divers need to use ear pressure equalization techniques to equalize ear pressure every time they dive to a certain depth. The mainstream ear pressure equalization techniques require pinching the nose or wearing a nose clip to prevent exhalation through the nose. Then, the air in the mouth and nasal cavity is pushed into the Eustachian tube to reach the middle ear cavity to equalize the ear pressure. If the ear pressure is unbalanced, the eardrum will be squeezed by the water pressure. It is necessary to be able to effectively equalize one's own ear pressure in order to have a comfortable and safe diving activity.

[0003] Nowadays, most recreational divers choose to wear well-known diving masks and use the method of pinching the nose to equalize ear pressure underwater; however, frequent pinching of the nose can easily lead to the following problems:

[0004] 1. The mirror is prone to leaking;

[0005] Second, changing posture increases water resistance and reduces movement efficiency;

[0006] 3. Increase oxygen consumption.

[0007] 4. During diving operations, divers may need to use their hands to operate other equipment, such as underwater photography, fishing and hunting, water dancing, etc., which makes it inconvenient to pinch their noses at the same time.

[0008] Professional or competitive freedivers use nose clips to replace pinching the nose for more efficient diving (the function of conventional nose clips is to permanently block the nose, preventing inhalation or exhalation). Although this eliminates the need to pinch the nose, it also makes it impossible to dive with conventional masks because a completely blocked nose prevents the mask from being compressed underwater. Therefore, freedivers can only dive with their eyes open or with fluid-filled eyepieces. Regardless of which method is used, the underwater field of vision and clarity are significantly reduced, increasing the risk of diving.

[0009] Moreover, the first condition for completing ear pressure balance is to block the nose, and balancing the mask requires exhaling through the nose. In other words, the nose needs to be in a blocked state when balancing the ear pressure, and in an unobstructed state when balancing the mask. This is difficult to achieve without the help of external forces such as the hands. Utility Model Content

[0010] The purpose of the present utility model is to provide a diving nose plug to solve the problems raised in the above background technology.

[0011] The purpose of the utility model can be achieved through the following technical solutions:

[0012] A diving nasal plug includes a plug body, wherein the plug body is a hollow structure, an air chamber is formed in the plug body, one end of the plug body is configured as a conical structure and forms an air inlet, and the other end of the plug body is an open structure and forms an air outlet;

[0013] An air inlet assembly is fixedly installed in the air chamber at one end near the air inlet, and an air outlet assembly is detachably fixedly installed in the air chamber at one end near the air outlet. A piston assembly is also installed in the air chamber for cooperating with the air inlet assembly or the air outlet assembly to control the opening and closing of the plug body;

[0014] An internal thread for use with an air outlet component is provided on the inner wall of the air chamber near the air outlet.

[0015] Furthermore, the air intake assembly includes an anti-backflow valve fixedly installed in the air chamber at one end near the air inlet.

[0016] Furthermore, the gas outlet assembly includes a gas outlet valve, and a central portion of the periphery of the gas outlet valve is provided with an external thread that cooperates with the internal thread on the inner wall of the gas chamber;

[0017] In the installed state, one end of the air outlet valve extends into the air chamber, and the air outlet valve and the air chamber are threadedly connected via an external thread and an internal thread.

[0018] Furthermore, a sealing ring is fixedly mounted on the periphery of the air outlet valve at one end located in the air chamber, and the sealing ring is in compression contact with the inner wall of the air chamber.

[0019] Furthermore, an adjustment ring for rotating the air outlet valve is fixedly installed on the periphery of the air outlet valve at one end located outside the air chamber.

[0020] Furthermore, the piston assembly includes a mounting ring fixedly installed in the air inlet, and the end of the mounting ring close to the air outlet valve is fixedly connected to a precision spring, and the end of the precision spring away from the mounting ring passes through the anti-backflow valve and is fixedly installed with a two-way piston located between the air outlet valve and the anti-backflow valve.

[0021] Furthermore, the outer periphery of the plug body is covered with a layer of silicone.

[0022] Beneficial effects of the utility model:

[0023] 1.

[0024] 2. In the present invention, by rotating the adjusting ring clockwise by hand, the outlet valve can move a certain distance to the right. In the process of the outlet valve and the two-way piston approaching, the critical pressure value will gradually decrease until (the outlet valve is completely closed when adjusted to the minimum); by rotating the adjusting ring counterclockwise, the outlet valve moves to the left, the distance between the outlet valve and the two-way piston gradually increases, and the critical pressure value will also gradually increase, and a greater pressure is required to achieve ear pressure balance; through this setting, the critical pressure value of the present invention can be flexibly adjusted within a certain range, thereby improving the practicality of the present invention.

[0025] 3. When the utility model is in use, the inhaled airflow pushes the two-way piston to move toward the air inlet, so that the two-way piston closes the anti-back-inhalation valve, thereby blocking the airflow from being inhaled into the nasal cavity. It has an anti-back-inhalation function and can avoid the occurrence of mask squeeze injuries. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1:

[0039] See also Figures 1 to 6 In an embodiment of the present invention, a diving nasal plug includes a plug body 1, which is a hollow structure. An air chamber 8 is formed in the plug body 1. One end of the plug body 1 is set to a conical structure and forms an air inlet 2. The other end of the plug body 1 is an open structure and forms an air outlet 3.

[0040] An air inlet assembly is fixedly installed in the air chamber 8 at one end near the air inlet 2, and an air outlet assembly is detachably fixedly installed in the air chamber 8 at one end near the air outlet 3. A piston assembly is also installed in the air chamber 8 for cooperating with the air inlet assembly or the air outlet assembly to control the opening and closing of the plug body 1;

[0041] An internal thread for use with an air outlet component is provided on the inner wall of the air chamber 8 near the air outlet 3 .

[0042] The air intake assembly includes an anti-backflow valve 10 fixedly installed in the air chamber 8 at one end close to the air inlet 2.

[0043] The gas outlet assembly includes a gas outlet valve 5, and an external thread 6 is provided at the middle portion of the periphery of the gas outlet valve 5 for use with the internal thread on the inner wall of the gas chamber 8;

[0044] In the installed state, one end of the air outlet valve 5 extends into the air chamber 8 , and the air outlet valve 5 and the air chamber 8 are threadedly connected via the external thread 6 and the internal thread.

[0045] An adjustment ring 4 for rotating the air outlet valve 5 is fixedly mounted on the periphery of the air outlet valve 5 at one end located outside the air chamber 8 .

[0046] Among them, the piston assembly includes a mounting ring 12 fixedly installed in the air inlet 2, and the end of the mounting ring 12 close to the air outlet valve 5 is fixedly connected to a precision spring 11. The end of the precision spring 11 away from the mounting ring 12 passes through the anti-backflow valve 10 and is fixedly installed with a two-way piston 9 located between the air outlet valve 5 and the anti-backflow valve 10.

[0047] like Figure 7 and Figure 8 As shown, the utility model is used in pairs and is worn in the two nostrils of the user (the end of the plug body 1 with the air inlet 2 is inserted into the nose); and the utility model does not affect the wearing of known diving masks when worn.

[0048] like Figure 2 As shown, when there is no airflow or only very weak airflow entering the air inlet 2, the two-way piston 9 does not contact the anti-backflow valve 10 or the air outlet valve 5. At this time, the air can be discharged normally from the air outlet 3. In this state, the user can breathe out normally through the nose and perform the mirror balance operation.

[0049] like Figure 3 As shown, when the air flow speed entering the air inlet 2 gradually increases and the air chamber 8 reaches a critical pressure value, the two-way piston 9 is driven by the air flow to move toward the air outlet 3 until it fits with the air outlet valve 5; at this time, the two-way piston 9 closes the air outlet valve 5, and the air flow no longer flows out. During the process, as long as the air intake pressure maintains a certain balance, the air outlet valve 5 always remains closed; in this state, the user's nose is blocked and cannot breathe out, so ear pressure balance can be performed.

[0050] When the intake air flow rate decreases below the critical pressure value, the two-way piston 9 is pulled back to the middle position between the outlet valve 5 and the anti-backflow valve 10 by the precision spring 11, and the air outlet 3 resumes ventilation; this reciprocating process allows the user to freely control the opening and closing state of the outlet valve 5 according to the amount of air exhaled from the nose, thereby freely completing the mask balance operation and ear pressure balance operation; wherein, the critical pressure value is an adjustable variable.

[0051] like Figure 4 As shown, during recreational diving, divers do not need to inhale through their noses under any circumstances. If they inhale while wearing a mask, it may cause mask crushing injury (referring to injuries caused by improper wearing of the diving mask or failure to flatten the mask in time during diving, causing the mask to stick to the face and cause pressure on the eyes, local skin or tissue). When the utility model is in use, the inhaled airflow pushes the two-way piston 9 to move towards the air inlet 2, so that the two-way piston 9 closes the anti-backflow valve 10, thereby blocking the airflow from being inhaled into the nasal cavity.

[0052] Research has found that the pressure at which each diver can achieve ear pressure equalization is different. Therefore, if the critical pressure value is fixed, the product's applicability will be low. On the contrary, if the valve is adjustable, the user can adjust the pressure to the most appropriate level according to their own situation, which not only improves efficiency but also increases comfort.

[0053] like Figure 5 and Figure 6 As shown, the critical pressure value of the utility model is adjustable. Specifically, by manually rotating the adjustment ring 4 clockwise, the outlet valve 5 can move a certain distance to the right. As the outlet valve 5 and the two-way piston 9 approach each other, the critical pressure value will gradually decrease until it reaches 0 (adjusting to the minimum will completely close the outlet valve 5);

[0054] When the adjusting ring 4 is rotated counterclockwise, the air outlet valve 5 moves to the left, the distance between the air outlet valve 5 and the two-way piston 9 gradually increases, and the critical pressure value will also gradually increase, so a greater pressure is required to achieve ear pressure balance; through this setting, the critical pressure value of the utility model can be flexibly adjusted within a certain range, thereby improving the practicality of the utility model.

[0055] Example 2:

[0056] See also Figure 2 Based on Example 1, a sealing ring 7 is fixedly mounted on the periphery of the outlet valve 5 at one end located in the air chamber 8. The sealing ring 7 is in pressurized contact with the inner wall of the air chamber 8. The provision of the sealing ring 7 improves the sealing between the outlet valve 5 and the air chamber 8, which helps ensure the stability of the present invention.

[0057] Example 3:

[0058] Based on Example 1, the periphery of the plug body 1 is covered with a layer of silica gel.

[0059] Using silicone to cover can improve the sealing performance of the nasal plug, prevent gas leakage, and stop water from flowing into the nasal cavity, protecting the diver's respiratory tract underwater; and the relatively soft silicone material can improve the overall user experience of the diving nasal plug, making the diver more comfortable and safer when diving.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
