Description

[Technical field]

[0001] The present invention relates to full face masks, and more particularly to breathable masks for snorkeling. [Background technology]

[0002] In order to allow the user to breathe freely through the mouth and nose, and to allow the user to inhale as clean air as possible, and to prevent the clean air from mixing with the exhaled dirty air as much as possible, and then to proceed to the next inhalation circulation, most of the current full face snorkel masks (i.e., so-called Full Face Snorkel Masks, FFSM) have the following features inside the mask body: eye The device is divided into an upper chamber covering the upper part of the upper chamber and a lower chamber covering the mouth and nose. This allows the clean air drawn in to enter the lower chamber in one direction via the upper chamber. Part of the dirty air exhaled is discharged via the drain valve of the lower chamber, and the remaining part is discharged via an independent exhaust passage. Both of the above exhaust passages are independently attached to the periphery of the upper chamber and communicate with the snorkel. The exhaust air does not stagnate in the upper chamber, but can reach the outside directly via the snorkel, and then enters the lower chamber again and is drawn in at the next intake. Although such a configuration with separate intake and exhaust is of course feasible, it is clearly lacking in both product cost and reliability.

[0003] First, in terms of intake, an intake check valve must be installed to allow air to enter the lower chamber from the upper chamber. Most intake check valves are mushroom-shaped (i.e., a soft circular valve body is combined with a hard circular hub valve seat) and are attached to a soft spacer that separates the upper and lower chambers. After the user puts on the mask, depending on the user's face shape, the spacer may be attached too tightly and pulled and deformed by pressure. In this case, the intake check valve will not be in the correct position, causing air leakage or will not function properly. Also, if the mask is attached too loosely, such problems will not occur, but water will leak easily. In addition, this type of structure requires many assembly parts and the procedure is complicated.

[0004] In addition, in terms of exhaust, the exhaust passage is of course made of soft material to make it waterproof. sealing Scar To It is very convenient to mold it together. However, the soft passage is also often pulled when worn by different users (especially if worn too tightly), and it deteriorates and deforms during use or over a long period of time, obstructing the exhaust path. Therefore, most exhaust passages are mainly composed of a hard main frame, a lens part, or a combination of these. However, such a structure is ultimately waterproof. sealing Scar To The exhaust passage needs to be fitted, which increases the cost and makes it difficult to effectively control the waterproof property. In addition, the hard exhaust passage is easily damaged in the event of a collision, and the product reliability is lacking. For the disadvantages of using a soft exhaust passage, please refer to the contents of Patent Document 1. For the disadvantages of using a hard exhaust passage as the main frame, please refer to the contents of Patent Document 2.

[0005] In view of the above, it has become a unified goal in the industry to simultaneously or partially solve the above problems, facilitate the intake and exhaust functions, and effectively control both the manufacturing and assembly costs. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] U.S. Pat. No. 1,079,3239 [Patent Document 2] U.S. Pat. No. 10,566,654 Summary of the Invention [Problem to be solved by the invention]

[0007] The main object of the present invention is to provide a respirator mask in which a support device is integrally installed in an appropriate area of ​​a hard lens portion. During assembly, the support device can appropriately reinforce the rigidity of a soft functional member (e.g., one-way intake valve, exhaust passage, or both) to ensure that the function is accurate and reliable. In this way, the functional member can still be manufactured using a soft waterproof material (e.g., silicone) that is low-cost and not complicated in structure, and thus the silicone waterproof material can be used. sealing Scar To Since the molding can be completed at the same time during production, the manufacturing and assembly costs are significantly reduced. sealing Scar To Since assembly is required, the present invention assumes that several reinforcing members are integrally added to the lens section. These reinforcing members may be separately required parts (for example, a blocking wall that supports a soft exhaust passage, or a hard rib that stabilizes the check valve structure), or may be parts that are originally required (for example, a hard valve seat of the check valve). In this way, the lens section becomes waterproof. sealing Scar To Since there is no need to add any other parts when assembling the device, the cost is significantly reduced, the assembly is easier, and the strength is better. [Means for solving the problem]

[0008] Based on the above object, the present invention specifically provides a breathable mask including a body and a snorkel. The snorkel and the body are capable of passing through the interiors of the body. The body includes a main frame, a lens module fitted into the main frame, and a waterproof sealing skirt, at least a portion of which is fitted into the main frame and the lens module and can be properly fitted to a user's face. The lens module has a lens portion and a support device. The support device is integrally molded with the lens portion at a certain distance inward from the outermost edge of the lens portion, and the waterproof sealing skirt is formed on the lens portion and is formed on the waterproof sealing skirt. sealing Scar T The support device is interconnected with the part to increase the rigidity of the area near the part. The support device can be a hard valve seat of the one-way intake valve, a reinforcing rib in the area near the one-way intake valve, or a blocking wall supporting the exhaust passage.

[0009] A secondary object of the present invention is to provide a lens module having the above-mentioned support device for use in a respirator mask, the lens portion being configured to cover only the user's eyes, or to cover the user's eyes, nose and mouth. [Brief description of the drawings]

[0011] The technical feature claimed in this invention is mainly a change in the lens structure of the mask. By adding a support member (ideally molded integrally) using the lens surface, the mask becomes waterproof. sealing Scar T Part of the existing component and / or waterproofing that is not strong enough sealing Scar To Support. Lens surface and waterproof sealing Scar To After assembly, the support members are waterproof. sealing Scar To This allows for interconnection. sealing Scar ToThis technology allows the lens surface to be made of a hard material and a soft waterproof material, which can enhance the rigidity of the lens in areas that require stronger support. sealing Scar To The present invention can be applied to any mask having a lens section that covers the user's eyes, nose, and mouth. Such masks include the existing "Full Face Snorkel Mask (FFSM) 1" (see FIG. 1A), that is, a mask in which the lens section 2 covers the user's eyes, nose, and mouth. The present invention can also be applied to another "diving mask 3" (see FIG. 1B) that covers only the eyes and nose, or to other derivative forms. In addition, the present invention can be applied to a "breathable mask 10" (see FIG. 2A) newly created by the inventor of the present invention, that is, a mask in which the lens section covers only the user's eyes, and the nose and mouth are covered by a frame and a waterproof sealing Scar T It is also possible to apply the mask to a snorkel mask that covers both. Since the masks can be structurally used together, the following description will be made of only the "mask 10 that allows breathing" and various modified forms thereof.

[0012] As shown in FIG. 2A and FIG. 2B, the breathable mask 10 includes a body 20 and a snorkel 30, and the snorkel 30 and the body 20 are fluid-permeable. The body 20 includes a main frame 21, a lens module 22, and a waterproof sealing skirt 23. The lens module 22 is fitted into the main frame 21. The waterproof sealing skirt 23 is at least partially fitted into the main frame 21 and the lens module 22. In this embodiment, only the front eye area 231 of the waterproof sealing skirt 23 is fitted into the main frame 21 and the lens module 22. The rear of the waterproof sealing skirt 23 can be properly fitted to the face of a user (not shown). In addition, after the user wears the mask 10, a headband 40 connected to two opposite sides of the main frame 21 can be properly fastened to the user's head. In addition, the chin band 41 provided below the waterproof sealing skirt 23 can be fixed to both sides of the head band 40 at three points by appropriately tightening the user's lower chin.

[0013] Preferably, a connector 221 is integrally installed above the lens module 22. The upper end of the connector 221 is connected to the snorkel 30 so as to play an intermediate role in transmitting airflow between the snorkel 30 and the main body 20. In this embodiment, the connector 221 is divided into a central intake pipe 222 and exhaust pipes 223 on both sides, which are independent of each other. The inside of the snorkel 30 is also divided into a central intake pipe 322 and exhaust pipes 323 on both sides, which are independent of each other, and communicate with the central intake pipe 222 and the exhaust pipe 223, respectively. However, the embodiment in which the snorkel 30 is responsible for both intake and exhaust in a concentrated manner is merely one embodiment, and is not limited thereto. For example, the present invention can be applied to a configuration in which the snorkel 30 is responsible for only intake and exhaust in another manner.

[0014] Also refer to FIG. 2C. The waterproof sealing skirt 23 has a spacer 235 which divides the inside of the body 20 into an upper chamber 25 and a lower chamber 26. When the user wears the breathable mask, the spacer 235 sits on the user's nose, and the user's eyes are accommodated in the upper chamber 25, and the user's nose or nose and mouth are accommodated in the lower chamber 26. In the embodiment shown in FIG. 2C, the user's nose and mouth are simultaneously accommodated in the lower chamber 26. The lens module 22 is also located correspondingly in the upper chamber 25. A drain valve 27 corresponds to the lower chamber 26 and is connected to a rigid mouth frame 31 and a waterproof sealing Scar T2 It is sandwiched between 3 and allows the user to drain water while also providing partial exhaust function.

[0015] 2D. With regard to intake, the upper chamber 25 and the lower chamber 26 are arranged to allow fluid to pass between them in one direction, and fresh gas in the upper chamber 25 is only allowed to enter the lower chamber 26 via the one-way intake valve 50. There is no duct for returning dirty exhaled air in the lower chamber 26 to the upper chamber 25. With regard to exhaust, the waterproof sealing skirt 23 is usually formed with an exhaust passage 232 extending along the outer periphery of the upper chamber 25, and dirty air in the lower chamber 26 is only allowed to pass through the exhaust passage 232 and be discharged to the outside. Furthermore, as shown by the hollow dotted line in FIG. 2D, when the user inhales, fresh air enters the upper chamber 25 from the intake pipe 322 of the snorkel 30 via the intake pipe 222 of the connector 221, clears away any fogging that may occur in the lens module 22, and then enters the lower chamber 26 through the one-way intake valve 50 and is inhaled by the user. When the user exhales through the mouth or nose, as shown in FIG. 2D, the dirty air passes through the exhaust pipe 223 of the connector 221 and the exhaust pipe 323 of the snorkel 30 along the exhaust passage 232 and is exhausted to the outside. In this way, a configuration is formed in which the intake and exhaust air are separated.

[0016] The lens module 22 is waterproof in any way. sealing Scar T2 Therefore, in the present invention, the lens module 22 is provided with some reinforcing members or is integrally molded with the lens module 22 to provide a soft waterproof structure. sealing Scar T2 3. This not only reduces the number of parts and the cost of parts, but also greatly reduces the assembly cost. Thus, the technical features of the present invention are formed. Specifically, the lens module 22 includes a lens unit 224 and a support device.

Similarly, the exhaust passage 532 has an exhaust passage inlet 534 and an inner peripheral wall 533. The support device has a first rib 51 and a second rib 52. The first rib 51 is disposed above the pivot check valve and is connected to the waterproof sealing skirt 53. sealing Scar T5On the other hand, the second rib 52 is fitted into the waterproof member 533 at a portion of the inner side wall 533 close to the exhaust passage inlet 534. sealing Scar T5 3, which strengthens the pivot check valve and prevents the structure from collapsing.

[0021] Similar to the embodiment of Figures 2A to 2E, Figures 5A, 5B and 5C show another embodiment of the present invention, but the intake check valve does not adopt a pivot check valve, but adopts a mushroom-type check valve. Also, the support device is similarly equipped with a waterproof sealing Scar ToIn order to facilitate and stably assemble the upper chamber 65, an integrally molded valve seat is provided in advance. Specifically, in this embodiment, the one-way intake valve is a mushroom-type check valve. The waterproof sealing skirt 63 is formed with an exhaust passage 632 extending along the outer periphery of the upper chamber 65. The lower chamber 66 is only allowed to pass fluid between the lower chamber 66 and the outside through the exhaust passage 632 to exhaust the user's exhaled air. The support device has a valve seat 625. The exhaust passage 632 has an exhaust passage inlet 634 and an inner side wall 633. An intake port 636 is provided at a location of the inner side wall 633 close to the exhaust passage inlet 634, and the valve seat 625 is attached to the intake port 636. A film 637 for blocking the intake port 636 is fixed to the center below the valve seat 625. As a result, the mushroom-shaped check valve is formed so that fresh air can flow only from the upper chamber 65 to the lower chamber 66. As in the embodiment of Figs. 2A to 2E, the support device further includes a blocking wall 638, and the exhaust passage 632 is located between the main frame 21 and the blocking wall 638. At least a portion of the blocking wall 638 is continuous, and at least a portion of the blocking wall 638 is installed in close contact with the inner side wall 633 of the exhaust passage 632. Preferably, the blocking wall 638 includes a plurality of female fasteners 639. In addition, a plurality of male fasteners 640 that can be appropriately fastened to the plurality of female fasteners 639 are provided on the outer side of the inner side wall 633 of the exhaust passage 632. As a result, the blocking wall 638 does not separate from the exhaust passage 632.

[0022] In the above preferred embodiment, the structure and operation of the technology of the present invention are described in detail, but other than that, for example, a pivot type, a mushroom type or other type of intake check valve, the installation position and number of the intake check valve, the type of the blocking wall, and the connection method with the exhaust passage, any other form that is modified based on the concept of the present invention, are all within the scope of the present invention without limitation, and should not be limited to the written description claimed in the following claims.
