Description

Technical Field

[0001] The utility model relates to a full-face mask, in particular to a breathable mask for snorkeling. Background Art

[0002] Some current full-face snorkel masks (FFSM) have adopted an intake and exhaust split design. In this design, the lower chamber of the mask (the chamber that covers the mouth and nose) is interconnected with the exhaust channel. When the user is snorkeling underwater, if he wants to drain the water in the mask, he must use his mouth to exhale vigorously to make it pass through the drain valve and overcome the strong water pressure outside to succeed.

[0003] However, the lower chamber of the mask needs to accommodate the user's nose and mouth, so it must occupy a considerable volume. Moreover, the lower chamber is interconnected with the exhaust channel, and the exhaust channel is interconnected with the outside world through the breathing tube, so that the lower chamber is not actually an ideal closed system. In addition, the actual exhaust path of the exhaust channel and the breathing tube is quite long, making it difficult to control the total volume of the lower chamber and the lower chamber as expected. Therefore, when the user wants to drain water by exhaling deeply, in this large space that is not absolutely closed, it is impossible to generate enough pressure to overcome the water pressure and successfully drain the water through the drain valve. Instead, the accumulated water in the lower chamber is brought into the exhaust channel at the edge of the mask body and retained therein. After the user finishes exhaling, the accumulated water naturally flows back into the mask body, so in fact, the accumulated water is almost not discharged.

[0004] In summary, the poor drainage efficiency comes from the insufficient exhalation pressure from the mouth, and the insufficient exhalation pressure and flow rate from the mouth come from the excessively large interconnected space where the mouth is located, and also from the fact that the space is not airtight and still communicates with the outside world. Specifically, the volume of the space includes the content volume of the lower chamber, the content volume of the exhaust channel set at the outer edge of the mask body, and the content volume of the exhaust pipe above the body. Moreover, the exhaust pipe above the body is still in fluid communication with the outside world, which is the reason why it is difficult to drive the accumulated water out through the drainage valve even if you exhale vigorously.

[0005] In other words, the design of FFSM generally has poor drainage efficiency during underwater activities. Users must surface and spit out the accumulated water or take off the mask to pour out the accumulated water, which is quite troublesome and greatly reduces the fun of snorkeling. This is a long-standing drainage problem of full-face masks. Even though the mask has been divided into an upper chamber that covers the eyes and a lower chamber that covers the nose and mouth, and the intake and exhaust are designed with split flow, it still cannot be effectively improved, and the industry urgently needs to continue to work hard to make breakthroughs.

[0006] In view of this, designing a snorkeling device that can partially or fully solve the above problems has become a goal that the industry strives to pursue. Utility Model Content

[0007] One purpose of the utility model is to provide a respirable mask with a manual pressing mechanism, so that when the user needs to drain water in the water, the user can press the mechanism with a finger to block the connection between the exhaust channel and the outside world, so that the lower chamber temporarily forms a closed space, and the exhalation pressure naturally increases significantly. Accordingly, the user can easily overcome the underwater pressure with minimal physical effort to discharge the accumulated water in the lower chamber of the mask through the drain valve.

[0008] To achieve the above-mentioned purpose, the utility model discloses a respirable mask, which includes a body and a breathing tube. The breathing tube is in fluid communication with an interior of the body, and includes an air inlet pipe and an exhaust pipe independent of the air inlet pipe. The body includes a main frame, a lens assembly, a waterproof sealing skirt, an air inlet channel and an exhaust channel. The lens assembly is embedded in the main frame. The waterproof sealing skirt is at least partially embedded with the main frame and the lens assembly, and can be fitted to the face of a user. The waterproof sealing skirt has a spacer that divides the interior of the body into an upper chamber and a lower chamber, so that when the user wears the respirable mask through a fastening device, the spacer is located above the user's nose, and the user's eyes are accommodated in the upper chamber, and the user's nose and mouth are accommodated in the lower chamber. The air inlet channel is formed from the air inlet pipe to the lower chamber. The exhaust channel is formed from the lower chamber to the exhaust pipe. The exhaust channel has a pressing area, which has an outer portion and an inner portion. The outer portion has an identifiable mechanism exposed to the outside, so that when the user's finger presses the outer portion through the identifiable mechanism, the outer portion is pressed against the inner portion to temporarily block the fluid communication between the exhaust passage and the outside.

[0009] In addition, to achieve the above-mentioned purpose, the utility model further discloses a body of a respirable mask. The body includes a main frame, a lens assembly, a waterproof sealing skirt and an exhaust passage. The lens assembly is embedded in the main frame. The waterproof sealing skirt is at least partially embedded with the main frame and the lens assembly, and can be fitted to the face of a user. The waterproof sealing skirt has a spacer that divides the interior of the body into an upper chamber and a lower chamber, so that when the user wears the respirable mask through a fastening device, the spacer is located above the user's nose, and the user's eyes are accommodated in the upper chamber, and the user's nose and mouth are accommodated in the lower chamber. The exhaust passage is connected to the lower chamber. The exhaust passage has a pressing area, which has an outer portion and an inner portion. The outer portion has an identifiable mechanism exposed to the outside world, so that when the user's finger presses the outer portion through the identifiable mechanism, the outer portion is squeezed and pressed against the inner portion to temporarily block the fluid communication of the exhaust passage to the outside world.

[0010] In one example, the outer portion is a soft outer portion, and the inner portion is a hard inner portion. The exhaust passage includes an exhaust tunnel extending along an outer periphery of the lens assembly and communicating with the lower chamber, and the pressing area is formed on the exhaust tunnel, so that when the user's finger presses the soft outer portion, the soft outer portion is pressed against the hard inner portion to temporarily block the exhaust tunnel.

[0011] In one example, the exhaust tunnel is defined by the waterproof sealing skirt and the inner surface of the lens assembly.

[0012] In one example, the lens assembly further includes a retaining wall arranged along the outer periphery, the retaining wall extending along an inner side wall of the exhaust tunnel, the soft outer portion of the pressing area being appropriately defined by an outer side wall of the exhaust tunnel, and the hard inner portion of the pressing area being appropriately defined by the retaining wall, so that when the user's finger presses the outer side wall of the exhaust tunnel, the outer side wall is squeezed against the retaining wall to temporarily block the exhaust tunnel.

[0013] In one example, the retaining wall and an inner side wall of the exhaust tunnel are interlocked with each other.

[0014] In one example, the identifiable mechanism is a pressing device formed on an outer surface of the pressing area.

[0015] In one example, the pressing device is a block.

[0016] In one example, the block is integrally formed with the waterproof sealing skirt. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The following description of the embodiments is only for explaining the content of the present invention, and is not intended to limit the present invention. Elements not directly related to the present invention, such as the headband for fixing the mask to the user's head, are not shown, and the size relationship between the elements in the drawings is only for easy understanding, and is not intended to limit the actual proportion. In addition, the spatial relationship of "inside" and "outside" is defined by the direction of the user, that is, closer to the user is called "inside", and farther away from the user is called "outside", and is not intended to limit the setting direction of the elements.

[0045] An embodiment of the present utility model is as follows Figures 1 to 3 shown. Figure 1 1 is a rear view of the respirable mask 1 of the present invention. The respirable mask 1 comprises a breathing tube 11 and a body 13. The breathing tube 11 is in communication with an internal fluid of the body 13.

[0046] Further references Figure 2, which is Figure 1 A coronal cross-sectional view of the respirable mask 1 along the section line 2-2. An air inlet pipe 112 and at least one exhaust pipe 114 longitudinally isolated from the air inlet pipe 112 are formed inside the breathing tube 11. The breathing tube 11 of this embodiment is illustrated by taking two exhaust pipes 114 longitudinally isolated on both sides of the air inlet pipe 112 as an example, but any changes in the number and position configuration of the exhaust pipes 114 of the breathing tube 11 should be within the scope of the embodiment of the present invention.

[0047] The body 13 includes a main frame 13a, a lens assembly 13b, a waterproof sealing skirt 13c, an air inlet passage, an exhaust passage and a drain valve 13f. The lens assembly 13b is embedded in the main frame 13a. At least part of the waterproof sealing skirt 13c (i.e., the front part corresponding to the user's eyes) is embedded with the main frame 13a and the lens assembly 13b. The waterproof sealing skirt 13c can fit the face of a user.

[0048] The waterproof sealing skirt 13c has a spacer 13c1, which divides the interior of the main body 13 into an upper chamber 202 and a lower chamber 204. When the user wears the respirator 1 through a fastening device (usually an elastic band connecting two sides of the main frame 13a, not shown in the figure), the spacer 13c1 is located above the user's nose, and the user's eyes are accommodated in the upper chamber 202, and the user's nose and mouth are accommodated in the lower chamber 204.

[0049] The air intake passage is formed from the air intake pipe 112 to the lower chamber 204, more specifically, between the lower end of the breathing pipe 11 and the lower chamber 204. Preferably, the body 13 has two air intake check valves 13d symmetrically arranged on the two outer sides of the spacer 13c1, so that the inhaled air can pass through the air intake passage in one direction and enter the lower chamber 204. In this way, the air intake passage is defined by the upper chamber 202 and the air intake check valve 13d, and the air intake passage is fluidically connected to the lower chamber 204. The two air intake check valves 13d are not limited in their arrangement positions, and can also be arranged on the spacer 13c1. In addition, although the air intake check valves 13d shown in the figure are all wing-shaped check valves, the actual shape and number are not limited. In other embodiments, mushroom-shaped or pivot-shaped check valves can also be selected.

[0050] The exhaust passage is formed from the lower chamber 204 to the exhaust pipe 114, and is in fluid communication with the lower chamber 204. The exhaust passage mainly includes two exhaust tunnels 132, which are formed between the lower end of the breathing tube 11 and the lower chamber 204. Each exhaust tunnel 132 is defined by the waterproof sealing skirt 13c and an inner surface 13b1 of the lens assembly 13b, and extends along the edge of the body 13. In this embodiment, the main frame 13a does not constitute a part of the exhaust tunnel 132.

[0051] In normal breathing, the exhaust path when the user exhales through the nose and / or mouth can be referred to Figure 2 At this time, because the drain valve 13f is kept closed by the external water pressure, the lower chamber 204 is essentially a closed space, so the exhaust air will naturally move through the space that is easy to walk, that is, the exhaled dirty air will go up along the two exhaust tunnels 132 independently set between the two exhaust pipes 114 and the lower chamber 204, and then be discharged to the outside through the two exhaust pipes 114 set in the breathing tube 11.

[0052] In the present invention, when the user needs to discharge the accumulated water in the mask during underwater activities, the user can easily overcome the underwater pressure without floating to the surface, and discharge the accumulated water in the lower chamber 204 through the drain valve 13f. In one embodiment, each exhaust tunnel 132 is further provided with a pressing area 132p. The pressing area 132p has an outer portion and an inner portion. Preferably, the outer portion is a soft outer portion P1, and the inner portion is a hard inner portion P2. The outer surface of the soft outer portion P1 is provided with an identifiable mechanism 13e exposed to the outside world. The identifiable mechanism 13e is a mechanism for the user to easily identify the location of the pressing area 132p by touching it with a finger.

[0053] More specifically, in this embodiment, the lens assembly 13b also includes a retaining wall 13b2 arranged along the outer periphery. The retaining wall 13b2 extends along an inner side wall 13c2 (a part of the waterproof sealing skirt 13c) of the exhaust tunnel 132, and the soft outer part P1 of the pressing area 132p is defined by an outer side wall 13c3 (another part of the waterproof sealing skirt 13c) of the exhaust tunnel 132, and the hard inner part P2 is defined by the retaining wall 13b2. In this way, when the user needs to drain water during underwater activities, he can easily find the identifiable mechanism 13e and press the soft outer part P1, so that the soft outer part P1 is squeezed and pressed against the hard inner part P2, so as to temporarily block the fluid connection between the exhaust tunnel 132 and the outside world, that is, Figure 3 As shown, the exhaust tunnel 132 is temporarily blocked. When the user stops pressing the soft outer portion P1, the soft outer portion P1 can return to its initial position without being pressed, so that the exhaust tunnel 132 returns to its initial unobstructed state.

[0054] The exhaust path when the user exhales through the mouth can be found in Figure 3 The airflow is shown by the dotted line in the middle. At this time, the area for the user to exhale forcefully is essentially only the area of ​​the lower chamber 204. If the position of the drainage valve 13f is designed to face the airflow from the user's mouth, the efficiency of exhalation drainage will be greatly improved. In this way, the design of the utility model allows the user to overcome the water pressure in the water and drain the water easily without surfacing, which saves more energy and adds to the fun of snorkeling.

[0055] Preferably, the retaining wall 13b2 and the inner side wall 13c2 of the exhaust tunnel 132 are interlocked. In other words, the portion of the waterproof sealing skirt 13c corresponding to the inner side wall 13c2 can be interlocked with the retaining wall 13b2 of the lens assembly 13b through the clip 13c4 formed by the waterproof sealing skirt 13c, so as to increase the rigidity of the exhaust tunnel 132, prevent the exhaust tunnel 132 from collapsing, and also enhance the strength of the engagement between the waterproof sealing skirt 13c and the lens assembly 13b.

[0056] The identifiable mechanism 13e of the present invention is now further described. As shown in the various figures, the identifiable mechanism 13e is presented as a pressing device. The pressing device can be a block, which is disposed on the outer surface of the pressing area 132p and exposed to the outside world to provide significant tactile identification. The design of the block can increase the operational reliability of the pressing device, so that the soft outer part P1 can be truly pressed against the hard inner part P2.

[0057] The arrangement of the pressing area 132p and the identifiable mechanism 13e can be arbitrarily changed according to the functional requirements. As long as the pressing area 132p itself remains soft on the outside and hard on the inside (that is, the relative hardness of the inside is higher than that of the outside, and can serve as a boundary after the external deformation), it is feasible to provide the user with a solution to press inward and temporarily block the exhaust passage from connecting to the outside. As for the material of the identifiable mechanism 13e, any shape of soft or hard material can be selected. The identifiable mechanism 13e is preferably formed integrally with the waterproof sealing skirt 13c (for example: made of silicone material to be integrally formed) to avoid the problem of falling off. However, in other embodiments, the identifiable mechanism 13e and the waterproof sealing skirt 13c can also be separated from each other and combined together by gluing or other means.

[0058] In one implementation, the identifiable mechanism may be a particle structure with multiple micro-protrusions, or any measure that allows the user to easily identify the position of the pressing area by touching it with a finger, which is feasible. In another implementation, the identifiable mechanism may also be a movable part, which is a part of the main frame and is located outside the soft outer part of the pressing area, so that the outer contour of the entire main frame and / or the breathing tube can still maintain its appearance continuity and integrity due to the existence of the pressing area, thereby enhancing the texture of the product, which is also feasible.

[0059] In other embodiments, an exhaust check valve (not shown) may be further provided at the connection between the exhaust tunnel 132 and the lower chamber 204 to further prevent the dirty air accumulated in the exhaust tunnel 132 from flowing back into the lower chamber 204 .

[0060] The technical focus of the present invention is that the exhaust passage has a pressing area, which allows the user to temporarily block the exhaust passage from being connected to the outside by pressing with a finger, and when the finger is released, the exhaust passage can be restored to be unobstructed. This technical concept can be used for any form of full-face mask, and the disclosed figures only use one type of breathable mask as an illustration. In other words, the structure of the main frame 13a, the lens assembly 13b (i.e., the viewing window) and the waterproof sealing skirt 13c in the disclosed figures is only for illustrative purposes, and any type of mask transformed based on the concept of the present invention belongs to the protection scope of the present invention, and should not be misunderstood as limiting the protection scope of the present invention.

[0061] In the present invention, preferably, the lens assembly 13b is a single-lens integrated type, and the breathing tube is composed of a single air intake tube 112 and two exhaust tubes 114. However, in other embodiments, the lens assembly is a double-lens separated type. The exhaust tube, exhaust tunnel or exhaust channel referred to in the above embodiments are preferably bilaterally symmetrical. However, for the sake of clarity and simplicity, only one of them is selected for explanation and advocacy in some descriptions, and the number is not limited.

[0062] As for the design of other parts, such as how the inlet and outlet pipes are formed (integrated into one breathing pipe or separated into two or more pipes), whether the lower chamber is further divided into two chambers, the number and shape of the lens assembly and the frame, the number and style of the inlet and outlet valves, etc., these are not the questions. The so-called breathing pipe can be directly extended outward from the top of the mask body, or it can be integrally extended from the lower end of the breathing pipe by the lens assembly 13b and then connected to the main body of the breathing pipe, such as Figure 2 , Figure 3 As shown, it is sufficient as long as the breathing tube body and the interior of the main body are in the required fluid communication.

[0063] Accordingly, the above embodiments are only used to illustrate the implementation methods of the utility model and to explain the technical features of the utility model, and are not used to limit the protection scope of the utility model. Changes or equivalent arrangements that can be easily completed by those skilled in the art are all within the scope claimed by the utility model, and the scope of protection of the utility model shall be based on the claims.
