Description

Technical Field

[0001] This utility model relates to an underwater activity mask, and more particularly to a mask for swimming, snorkeling, freediving, shooting fish and other water activities (including above-water and underwater), and the mask usually covers the user's eyes and nose. Background Technology

[0002] Common types of masks used for water activities include swimming goggles that only cover the eyes or snorkeling masks that cover both the eyes and nose, as well as other general diving masks, training goggles, freediving and fish-shooting masks with similar structures. Later, full-face breathing masks that cover the eyes, nose and mouth were also developed.

[0003] In the design of snorkeling masks, to avoid discomfort caused by the hard areas (i.e., the frame and viewing window) touching the user's face (especially the bridge and root of the nose), this area must protrude forward, thus maintaining a distance from the user's face. Consequently, in terms of visibility, the viewing window must be relatively large to ensure sufficient visibility for underwater activities. However, these design features are clearly detrimental to making the mask smaller and lighter.

[0004] Furthermore, structurally, to enhance the strength of the large viewing window, reinforced glass is typically used. This undoubtedly increases the weight of the viewing window area significantly, pulling the entire front of the mask downwards. Consequently, it affects the watertightness of the rear of the waterproof sealing skirt (the part of the waterproof sealing skirt that touches the face). Therefore, it's necessary to increase the wall thickness of the waterproof sealing skirt (especially the sides and top) to compensate for the mask's overall strength and balance the weight distribution between the front and back of the mask, resulting in better balance and stability when worn. It's conceivable that current designs are the reason why masks cannot be miniaturized, are burdensome to use, and are inconvenient to carry.

[0005] On the other hand, when users are freediving, shooting fish, or swimming training, the mask covering their eyes and nose cannot provide breathing space. Users must take a deep breath and hold it to complete the activity for a certain period. Therefore, if the mask's internal volume is too large, under water pressure, the space inside the mask will be compressed and pressed against the user's face, often forcing the user to exhale some air to balance the pressure. In other words, the larger the mask's internal volume, the more air needs to be exhaled, thus sacrificing breath-holding time and severely impacting the duration of activity. This is another reason why the internal volume of masks cannot be designed to be too large.

[0006] In view of this, designing a water mask that can partially or completely solve the above problems, and that offers advantages such as miniaturization, a better fit to the face, and sufficient strength, has become a goal that the industry is striving for. Utility Model Content

[0007] The main objective of this invention is to provide a face mask for underwater activities. Taking an underwater face mask that covers the eyes and nose as an example, there is no need to set up an airflow channel inside it; it only needs to achieve water tightness. Water tightness is usually achieved by the back of the soft, waterproof sealing skirt that fits against the face. Therefore, if the front of the waterproof sealing skirt and the viewing window have a good seal, good water tightness can be achieved.

[0008] Furthermore, because eyeglass frames are usually made of rigid materials, they not only reinforce the overall structure of the mask but also, due to their position at the front, showcase the product's unique appearance, making them a key factor for consumers when making a purchase. However, in reality, eyeglass frames do not need to function as watertight devices.

[0009] In view of this, the present invention provides a pair of relatively small viewing windows, embedded in a waterproof sealing skirt with a corresponding hollow front. The waterproof sealing skirt covers the user's eyes and nose, maintaining a watertight seal with the user's face. For a unique appearance, the present invention further provides a small frame, allowing the user to attach it to the waterproof sealing skirt as desired, and easily detach it when not in use. This small frame is not only easy to store and reusable, but can also be designed in different styles and colors for easy replacement. In some designs, the present invention also allows for relative movement between the waterproof sealing skirt and the frame, allowing the waterproof sealing skirt to fit the user's face more closely without being restricted by a rigid frame. In applications such as freediving, fish shooting, or swimming training, because the space inside the mask is extremely small, the air inhaled and held by the user beforehand does not need to be exhaled to balance the pressure inside and outside the mask, allowing for longer and more enjoyable underwater activities.

[0010] To achieve the above objectives, this utility model discloses a mask for underwater activities. The mask includes a waterproof sealing skirt, a left viewing window, a right viewing window, a headband, and a frame. The waterproof sealing skirt has a left skirt portion, a right skirt portion, a nose shield portion, and a rear portion. The left skirt portion defines a left hollow front portion. The right skirt portion defines a right hollow front portion. The nose shield portion is integrally formed between the left and right skirt portions. The rear portion is adapted to fit only around the user's eyes and nose. The left viewing window is fitted into the left hollow front portion. The right viewing window is fitted into the right hollow front portion. The headband extends rearward along the left and right sides of the waterproof sealing skirt. Each of the left and right viewing windows has a width between 30mm and 60mm and a height between 20mm and 50mm. The frame is detachably mounted on the waterproof sealing skirt along the periphery of the left and right hollow front portions.

[0011] In one example, the left and right view windows are two-piece view windows with separate mirrors on the left and right sides.

[0012] In one example, the frame has a left frame, a right frame, and a bridging member connecting the left and right frames, and the outer edges of the left and right hollow front portions of the waterproof sealing skirt correspond to the outlines of the left and right frames, respectively.

[0013] In one embodiment, the left frame has at least one first engaging groove for receiving a first periphery of the left hollow front portion, and the right frame has at least one second engaging groove for receiving a second periphery of the right hollow front portion.

[0014] In one example, at least one first engagement slot of the left frame includes three first engagement slots evenly distributed on the left frame, and at least one second engagement slot of the right frame includes three second engagement slots evenly distributed on the right frame.

[0015] In another embodiment, the left frame has at least one first engaging hole and the right frame has at least one second engaging hole, and the left skirt has at least one first engaging block and the right skirt has at least one second engaging block, so that when the frame is mounted on the waterproof sealing skirt, the at least one first engaging block is correspondingly engaged in the at least one first engaging hole and the at least one second engaging block is correspondingly engaged in the at least one second engaging hole.

[0016] In one example, the at least one first engaging hole of the left frame includes two first engaging holes, respectively located on an upper frame portion and a lower frame portion of the left frame, and the at least one second engaging hole of the right frame includes two second engaging holes, respectively located on an upper frame portion and a lower frame portion of the right frame. Furthermore, the at least one first engaging block of the left skirt includes two first engaging blocks, respectively located on an upper portion and a lower portion of the left skirt, and the at least one second engaging block of the right skirt includes two second engaging blocks, respectively located on an upper portion and a lower portion of the right skirt.

[0017] In one example, the waterproof sealing skirt also includes a recess that extends along at least a portion of the outer contour of the frame.

[0018] In another embodiment, the left viewing window has a first side groove defined by a first outer side wall and a first inner side wall opposite to the first outer side wall, and the right viewing window has a second side groove defined by a second outer side wall and a second inner side wall opposite to the second outer side wall. The first inner side wall and the second inner side wall are respectively fitted into the left hollow front portion and the right hollow front portion. Furthermore, the left frame has at least one first engaging member for engaging with the first outer side wall of the first side groove, and the right frame has at least one second engaging member for engaging with the second outer side wall of the second side groove, thereby fixing the mirror frame to the waterproof sealing skirt.

[0019] In one example, the at least one first latching member of the left frame comprises three first latching members evenly distributed in the left frame, and the at least one second latching member of the right frame comprises three second latching members evenly distributed in the right frame.

[0020] In one example, the waterproof sealing skirt also includes a recess that extends along at least a portion of the outer contour of the frame.

[0021] In another embodiment, the underwater mask of the present invention further includes a pivotable device disposed on two opposite outer sides of the mask frame, which detachably mounts the mask frame onto the waterproof sealing skirt.

[0022] In one example, the pivotable device includes a left pin and a right pin, each having a substantially cane-like structure. The left pin is inserted through an outer through-hole in the left frame and an outer through-hole in the left skirt, and the right pin is inserted through an outer through-hole in the right frame and an outer through-hole in the right skirt, thereby allowing the waterproof sealing skirt and the frame to pivot relative to each other along the left and right pins.

[0023] In one example, the left frame has a first fixing hole, and the right frame has a second fixing hole. A first head of the left pin has a first latch, and a second head of the right pin has a second latch. The first latch and the second latch are respectively inserted into the first fixing hole and the second fixing hole to lock the left pin and the right pin on the left and right frames, so as to prevent the frame from completely separating from the waterproof sealing skirt.

[0024] The beneficial effect of this utility model is that it provides a detachable small frame that users can attach to, for example, a waterproof sealing skirt for a snorkeling mask. This not only reduces the overall weight and volume of the mask, but also allows the frame to be designed in various styles for users to replace, increasing the variability of the design and color scheme, and further increasing consumers' desire to buy, without affecting the original comfort and water tightness of the mask.

[0093] The following descriptions of the various embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Components not directly related to the present invention are not shown, and the dimensional relationships between the components in the drawings are for ease of understanding only and are not intended to limit the actual proportions. Furthermore, terms such as up, down, front, back, left, right, inside, and outside in the descriptions are defined based on the user's orientation and are only relative relationships, not limitations. When a component name involves both a first and a second, and only the detailed structure of one is described, it means that both have the same structure, especially a symmetrical structure, and therefore will not be repeated below. In addition, to make the parts in the drawings clearer, some necessary parts (e.g., headbands) are omitted in some drawings.

[0094] The common basic structure of all embodiments of this utility model is described together here, but is distinguished by different component numbers, wherein the numbers beginning with "1", "2", "3", and "4" correspond to the first embodiment, respectively. Figures 1A to 1C The second embodiment Figures 2A to 2C The third embodiment Figures 3A to 3C and the fourth embodiment Figures 4A to 4D The component with the same name referred to in the text.

[0095] A water-based activity mask 1, 2, 3, 4 includes a waterproof sealing skirt 11, 21, 31, 41, a left viewing window 13L, 23L, 33L, 43L, a right viewing window 13R, 23R, 33R, 43R, a mirror frame 15, 25, 35, 45, and a headband 17, 27, 37, 47. To avoid the headband obscuring the main structure of this invention, the complete headband is largely omitted from the accompanying drawings.

[0096] The waterproof sealing skirt has a left skirt portion 11L, 21L, 31L, 41L, a right skirt portion 11R, 21R, 31R, 41R, a nose mask portion 11N, 21N, 31N, 41N, and a rear portion 11E, 21E, 31E, 41E. The left skirt portions 11L, 21L, 31L, 41L and the right skirt portions 11R, 21R, 31R, 41R respectively define a left hollow front portion LH1, LH2, LH3, LH4 and a right hollow front portion RH1, RH2, RH3, RH4. The nose mask sections 11N, 21N, 31N, and 41N are integrally formed between the left skirt sections 11L, 21L, 31L, and 41L and the right skirt sections 11R, 21R, 31R, and 41R. The rear sections 11E, 21E, 31E, and 41E can fit snugly around a user's eyes and nose, and isolate the user's mouth outside the waterproof sealing skirts 11, 21, 31, and 41. The left viewing windows 13L, 23L, 33L, and 43L and the right viewing windows 13R, 23R, 33R, and 43R are respectively fitted into the left hollow front sections LH1, LH2, LH3, and LH4 and the right hollow front sections RH1, RH2, RH3, and RH4.

[0097] Each of the left viewing windows 13L, 23L, 33L, 43L and the right viewing windows 13R, 23R, 33R, 43R has a width W between 30mm and 60mm and a height H between 20mm and 50mm. A height H between 35mm and 40mm and a width W between 45mm and 50mm are preferred, thus providing a sufficient visual area even after fitting into the left and right skirts respectively. This configuration achieves better results in miniaturization and balanced weight distribution of the entire mask without obstructing the user's required field of vision. The aforementioned width W and height H are perpendicular to each other and were measured based on the maximum lateral and longitudinal measurements after the user wears the mask.

[0098] Preferably, the left viewing windows 13L, 23L, 33L, 43L and the right viewing windows 13R, 23R, 33R, 43R are two-piece viewing windows with separate left and right mirrors, also known as "double-mirror style". Of course, with appropriate design, the left viewing windows 13L, 23L, 33L, 43L and the right viewing windows 13R, 23R, 33R, 43R can also be integrally formed into a single-piece "single-mirror style" (not shown in the figure), which is also feasible. In the embodiment of the single-mirror viewing window, the left hollow front parts LH1, LH2, LH3, LH4 and the right hollow front parts RH1, RH2, RH3, RH4 are also interconnected to cooperate with the design of the single-mirror viewing window and achieve the required watertightness.

[0099] The frames 15, 25, 35, and 45 are detachably mounted on the waterproof sealing skirts 11, 21, 31, and 41 along the periphery of the left hollow front portions LH1, LH2, LH3, and LH4 and the right hollow front portions RH1, RH2, RH3, and RH4. This adds a unique appearance to the mask and allows for easy removal from the waterproof sealing skirts 11, 21, 31, and 41 when not in use. Preferably, the frames 15, 25, 35, and 45 may have a left frame 15L, 25L, 35L, and 45L, a right frame 15R, 25R, 35R, and 45R, and a bridging member 15B, 25B, 35B, and 45B connecting the left frame 15L, 25L, 35L, and 45L and the right frame 15R, 25R, 35R, and 45R. Frames 15, 25, 35, and 45 can be made of rigid materials, especially rigid materials with a certain degree of flexibility, allowing frames 15, 25, 35, and 45 to withstand a certain degree of bending without easily breaking.

[0100] Furthermore, the outer edges of the left hollow front portions LH1, LH2, LH3, LH4 and the right hollow front portions RH1, RH2, RH3, RH4 of the waterproof sealing skirts 11, 21, 31, and 41 can correspond to the outlines of the left frames 15L, 25L, 35L, 45L and the right frames 15R, 25R, 35R, 45R, respectively, making the overall appearance more integrated after assembly. Of course, it is also feasible to have only the outer edges of the left hollow front portions LH1, LH2, LH3, LH4 and the right hollow front portions RH1, RH2, RH3, RH4 of the waterproof sealing skirts 11, 21, 31, and 41 have the same outlines as the inner edges of the left frames 15L, 25L, 35L, 45L and the right frames 15R, 25R, 35R, 45R, respectively, so that the left frames 15L, 25L, 35L, 45L and the right frames 15R have the same outlines, thus making the inner edges of the left frames 15L, 25L, 35L, 45L and the right frames 15R have the same outlines. The inner edges of 15L, 25R, 35R, and 45R engage with the outer edges of the left hollow front parts LH1, LH2, LH3, and LH4 and the right hollow front parts RH1, RH2, RH3, and RH4 of the waterproof sealing skirts 11, 21, 31, and 41. The outer edges of the left frame 15L, 25L, 35L, and 45L and the right frame 15R, 25R, 35R, and 45R can also be extended into different shapes to provide users with a wider variety of styles to choose from.

[0101] Furthermore, any connection structure that allows the frames 15, 25, 35, and 45 to be properly connected to the waterproof sealing skirts 11, 21, 31, and 41, achieving the purpose of detachably mounting the frames 15, 25, 35, and 45 onto the waterproof sealing skirts 11, 21, 31, and 41, is a feasible alternative and is what this utility model intends to protect.

[0102] Headbands 17, 27, 37, and 47 can extend backward along the left and right sides of waterproof sealing skirts 11, 21, 31, and 41. Headbands 17, 27, 37, and 47 can be connected to waterproof sealing skirts 11, 21, 31, and 41 or frames 15, 25, 35, and 45 via additional connectors, or can be directly fastened to the connection structure of waterproof sealing skirts 11, 21, 31, and 41 or frames 15, 25, 35, and 45; all of these are feasible design solutions.

[0103] To make the description clear and easy to understand, the above description only provides a preliminary description of the common features of the various embodiments of this utility model. The differences and features of the various embodiments of this utility model will be further described below, and the common features mentioned above will not be repeated.

[0104] The first embodiment of this utility model is as follows: Figures 1A to 1C As shown, it depicts a mask 1 for underwater activities. The left frame 15L of the mask frame 15 may have at least one first engaging groove ES1 for accommodating a first periphery P1 of the left hollow front portion LH1 of the waterproof sealing skirt 11, and the right frame 15R of the mask frame 15 may have at least one second engaging groove ES2 for accommodating a second periphery P2 of the right hollow front portion RH1 of the waterproof sealing skirt 11. Preferably, the left frame 15L has three first engaging grooves ES1 evenly distributed on the left frame 15L, and the right frame 15R has three second engaging grooves ES2 evenly distributed on the right frame 15R.

[0105] When the frame 15 is installed on the waterproof sealing skirt 11, the first locking groove ES1 and the second locking groove ES2 respectively accommodate the first periphery P1 of the left hollow front part LH1 and the second periphery P2 of the right hollow front part RH1 of the waterproof sealing skirt 11. The user only needs to exert a little force to pry open the frame 15, so that the first locking groove ES1 and the second locking groove ES2 disengage from the first periphery P1 and the second periphery P2 respectively, and the frame 15 can be removed from the waterproof sealing skirt 11. At this time, the waterproof sealing skirt 11 can be folded in half and stored using the soft material between the left viewing window 13L and the right viewing window 13R, making it more convenient to carry.

[0106] Furthermore, when the frame 15 is made of a rigid material with a certain degree of flexibility, the left frame 15L may have a single continuous annular first engaging groove ES1 to accommodate the entire first periphery P1 of the left hollow front part LH1, and the right frame 15R may have a single continuous annular second engaging groove ES2 to accommodate the entire second periphery P2 of the right hollow front part RH1. In this way, the frame 15 can be more securely engaged with the waterproof sealing skirt 11, and it is not easy for it to be easily separated by external force when moving in water.

[0107] In addition, in this embodiment, the left and right sides of the frame 15 may be provided with connecting structures F1 so that the headband 17 can be directly tied to them.

[0108] For example, in the second embodiment of this utility model Figures 2A to 2C As shown, it depicts a mask 2 for underwater activities. The left frame 25L of the mask frame 25 has at least one first engaging hole SH1, and the right frame 25R of the mask frame 25 has at least one second engaging hole SH2. Correspondingly, the left skirt portion 21L of the waterproof sealing skirt 21 has at least one first engaging block SB1, and the right skirt portion 21R of the waterproof sealing skirt 21 has at least one second engaging block SB2. In this way, when the mask frame 25 is mounted on the waterproof sealing skirt 21, at least one first engaging block SB1 is correspondingly engaged in at least one first engaging hole SH1 and at least one second engaging block SB2 is correspondingly engaged in at least one second engaging hole SH2.

[0109] Better, such as Figures 2A to 2C As shown, the left frame 25L has two first engaging holes SH1, located on the upper and lower parts of the left frame 25L respectively, and the right frame 25R has two second engaging holes SH2, located on the upper and lower parts of the right frame 25R respectively. Correspondingly, the left skirt 21L has two first engaging blocks SB1, located on the upper and lower parts of the left skirt 21L respectively, and the right skirt 21R has two second engaging blocks SB2, located on the upper and lower parts of the right skirt 21R respectively.

[0110] Of course, in other embodiments, this utility model can also adopt other male-female configurations, such as locking holes on the left and right skirts, and locking blocks on the left and right frames. In this type of male-female configuration, when the frame 25 is assembled to the waterproof sealing skirt 21, the first locking block SB1 and the second locking block SB2 are respectively locked into the first locking hole SH1 and the second locking hole SH2. The user only needs to press the first locking block SB1 and the second locking block SB2 with a little force to make them detach from the first locking hole SH1 and the second locking hole SH2, thereby achieving the purpose of separating the frame 25 from the waterproof sealing skirt 21. At this time, the waterproof sealing skirt 21 can be folded and stored along the soft material between the left viewing window 23L and the right viewing window 23R, making it more convenient to carry.

[0111] The waterproof sealing skirt 21 may also include a recess RC2 that extends along at least a portion of the outer contour of the frame 25, preferably continuously along the outer contour of the frame 25, resembling a hollow reinforcing rib, so as to more accurately align with the user's eye socket. This not only increases the stability of the structure of the mask 2 for water activities, but also achieves a more secure wearing effect.

[0112] In addition, in this embodiment, a connector F2 is provided on each side of the waterproof sealing skirt 21 for connecting the headband 27.

[0113] For example, the third embodiment of this utility model Figures 3A-3CAs shown, it depicts a mask 3 for underwater activities. The mask 3 for underwater activities provides an assembly structure consisting of a waterproof sealing skirt 31, a left viewing window 33L, a right viewing window 33R, and a mirror frame 35.

[0114] The left viewing window 33L has a first side recess SG1, defined by a first outer side wall TS1 and a first inner side wall NS1 opposite to the first outer side wall TS1. Similarly, the right viewing window 33R has a second side recess SG2, defined by a second outer side wall TS2 and a second inner side wall NS2 opposite to the second outer side wall TS2.

[0115] The first inner sidewall NS1 and the second inner sidewall NS2 are respectively fitted into the left hollow front portion LH3 and the right hollow front portion RH3 of the waterproof sealing skirt 31. The left frame 35L of the frame 35 has at least one first engaging member HD1 for engaging with the first outer sidewall TS1 of the first side groove SG1, and the right frame 35R of the frame 35 has at least one second engaging member HD2 for engaging with the second outer sidewall TS2 of the second side groove SG2, thereby fixing the frame 35 to the waterproof sealing skirt 31. In this way, the user only needs to exert a little force to pry open the frame 35, so that the first engaging member HD1 and the second engaging member HD2 are respectively disengaged from the first outer sidewall TS1 and the second outer sidewall TS2, and the frame 35 can be detached from the waterproof sealing skirt 31. At this time, the waterproof sealing skirt 31 can be folded and stored along the soft material between the left viewing window 33L and the right viewing window 33R, making it more convenient to carry.

[0116] Preferably, the left frame 35L has three first snap-fit ​​pieces HD1, which are evenly distributed on the left frame 35L, and the right frame 35R has three second snap-fit ​​pieces HD2, which are evenly distributed on the right frame 35R.

[0117] Similarly, the waterproof sealing skirt 31 may also include a recess RC3 that extends along at least a portion of the outer contour of the frame 35, preferably continuously along the outer contour of the frame 35, resembling a hollow reinforcing rib, so as to more accurately align with the user's eye socket. This not only increases the stability of the structure of the mask 3 for water activities, but also achieves a more secure wearing effect.

[0118] In addition, in this embodiment, a connector F3 is provided on each side of the waterproof sealing skirt 31 for connecting the headband 37.

[0119] For example, the fourth embodiment of this utility model Figures 4A to 4D As shown, it depicts a mask 4 for underwater activities. The mask 4 for underwater activities also provides an additional assembly structure of a waterproof sealing skirt 41 and a frame 45.

[0120] In detail, the underwater activity mask 4 also includes a pivotable device PD located on the two opposite outer sides of the mask frame 45, which can detachably mount the mask frame 45 onto the waterproof sealing skirt 41.

[0121] Preferably, the pivotable device PD includes a left latch LP and a right latch RP. For example, such as Figure 4A As shown, the left pin LP and right pin RP can each have a substantially cane-like structure or a shape similar to the number "7". The left pin LP is inserted through the outer through-hole FV1 of the left frame 45L and the outer through-hole SV1 of the left skirt 41L. The right pin RP is inserted through the outer through-hole FV2 of the right frame 45R and the outer through-hole SV2 of the right skirt 41R. In this way, the waterproof sealing skirt 41 and the frame 45 can pivot relative to each other along the left pin LP and right pin RP, as... Figure 4C As shown.

[0122] This design takes into account that the frame 45 is mostly made of rigid material, while the waterproof sealing skirt 41 is made of soft material. Therefore, the two are connected only on their corresponding outer sides (the outer side of the left frame 45L corresponds to the outer side of the left skirt 41L, and the outer side of the right frame 45R corresponds to the outer side of the right skirt 41R). This allows the waterproof sealing skirt 41 to fit the user's face more closely and not be restricted by the rigid frame 45, thereby improving wearing comfort and achieving better water tightness.

[0123] A preferred pivoting structure for a pivotable device PD is as follows: Figure 4D As shown. The left frame 45L may have a first fixing hole FH1, and the right frame 45R may have a second fixing hole FH2. In addition, a first head D1 of the left pin LP may have a first latch T1, and a second head D2 of the right pin RP may have a second latch T2. In this way, the first latch T1 and the second latch T2 can be inserted into the first fixing hole FH1 and the second fixing hole FH2 respectively to lock the left pin LP and the right pin RP on the left frame 45L and the right frame 45R, so as to prevent the frame 45 from completely separating from the waterproof sealing skirt 41.

[0124] Preferably, the first head D1 of the left pin LP may also have a first handle A1, and the second head D2 of the right pin RP may also have a second handle A2. With this pivoting structure, when the frame 45 is installed on the waterproof sealing skirt 41 and the user wants to remove the frame 45, the user can forcefully turn the first handle A1 of the left pin LP and the second handle A2 of the right pin RP with their fingers to disengage the first latch T1 and the second latch T2 from the first fixing hole FH1 and the second fixing hole FH2 respectively, thus allowing the left pin LP and the right pin RP to be pulled out. At this time, the frame 45 can be completely separated from the waterproof sealing skirt 41. Figure 4A As shown in the diagram. Therefore, this pivoting structure makes the frame 45 quite easy to assemble and disassemble.

[0125] In addition, in this embodiment, a connector F4 is provided on each side of the waterproof sealing skirt 41 for connecting the headband 47.

[0126] The key feature of this invention is to provide a detachable small frame that users can attach to, for example, a waterproof sealing skirt for a snorkeling mask. This not only reduces the overall weight and size of the mask, but also allows the frame to be designed in various styles for users to replace, increasing the variability in shape and color scheme, and further increasing consumers' desire to buy, without affecting the original comfort and watertightness of the mask.

[0127] The technical spirit of this utility model is as described above. Other aspects, such as the design of the headband, the selection of materials, the type of equipment it is applied to, or changes in the form of the left and right viewing windows, are not relevant here. Therefore, anything based on the aforementioned core technology of this utility model is subject to its protection.

[0128] The above embodiments are merely illustrative of the implementation methods of this utility model and to explain its technical features, and are not intended to limit the scope of protection of this utility model. Any changes or equivalent arrangements that can be easily made by those skilled in the art are within the scope claimed by this utility model.
