However, existing VR masks typically only offer top and bottom ventilation, resulting in less than ideal breathability. After prolonged use, users often experience stuffiness and discomfort, and the masks can easily fog up the main unit's lens and the glasses' lenses. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a VR ventilation mask to solve the problem of unsatisfactory ventilation and breathability of existing VR masks.

The mask body includes an outer shell plate, and the outer shell plate has a plurality of first ventilation holes. Each first ventilation hole has a baffle extending towards the light-blocking plate on its side. The light-blocking plate is disposed on the mask body and located inside the outer shell plate. There is a first ventilation gap between the light-blocking plate and the outer shell plate. The light-blocking plate has a plurality of first ventilation holes that cooperate with the first ventilation holes. The first ventilation holes are offset from the first ventilation holes. The first ventilation holes, the first ventilation gap, and the first ventilation holes are sequentially connected to form a stepped first light-blocking ventilation channel.

[0005] Furthermore, in the VR ventilated mask of this utility model, the opening of the first vent is disposed facing the non-opening area of ​​the light-blocking plate, and the opening of the first ventilation hole is disposed facing the non-opening area of ​​the outer shell plate, so that the first ventilation hole and the first vent are offset.

[0006] Furthermore, in the VR ventilation mask of this utility model, the long axis of the first vent extends parallel to the vertical height direction of the VR ventilation mask.

[0007] Furthermore, in the VR ventilated mask of this utility model, the baffle includes a first baffle and a second baffle, and the first baffle and the second baffle are respectively located on different sides of the first vent.

[0008] Furthermore, in the VR ventilated mask of this utility model, the outer shell plate is provided with a guide, and the light-blocking plate is provided with a downward-facing slot, wherein the guide is disposed in the slot.

[0009] Furthermore, the VR ventilated mask of this utility model also includes a first light-shielding plate, which is disposed on the mask body. The light-blocking plate is disposed between the outer shell plate and the first light-shielding plate, and there is a second ventilation gap between the first light-shielding plate and the light-blocking plate.

[0010] Furthermore, in the VR ventilated mask of this utility model, the outer shell plate is provided with a plurality of second ventilation holes, and the bottom of the light-blocking plate is provided with a ventilation notch.

[0013] The beneficial effects of this utility model are as follows: This utility model proposes a VR ventilated mask, aiming to solve the problem of poor ventilation and light-blocking performance of existing VR masks. The VR ventilated mask includes an outer shell plate and a light-blocking plate separated by a first ventilation gap.

[0041] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0042] Existing VR ventilated masks on the market typically only offer top and bottom ventilation, with a ventilation area of ​​less than one-third of the outer surface area. This results in less than ideal ventilation and breathability, leading to fogging of the main unit's lens and glasses even after using the mask. To address these issues, this invention maximizes the ventilation grille, achieving both light blocking and a fully enclosed, all-around ventilation structure.

[0043] Please refer to Figures 1 to 2 This utility model provides a VR ventilated mask, which includes a mask body 1 and a light-blocking plate 3. The mask body includes an outer shell plate 2, on which a plurality of first ventilation holes 21 are formed. Each first ventilation hole 21 has a baffle extending towards the light-blocking plate 3 on its side. The light-blocking plate 3 is disposed on the mask body and located on the inner sidewall of the outer shell plate 2. A first ventilation gap 4 is formed between the light-blocking plate 3 and the outer shell plate 2. The light-blocking plate 3 has a plurality of first ventilation holes 31 that cooperate with the first ventilation holes 21. The first ventilation holes 31 are offset from the first ventilation holes 21. The first ventilation holes 21, the first ventilation gap 4, and the first ventilation holes 31 are sequentially connected to form a stepped first light-blocking ventilation channel. The mask body is generally similar to a ring structure to form a viewing opening, and the aforementioned inner side is the side close to the viewing opening.

[0044] As can be seen from the above description, the beneficial effects of this utility model are as follows: This utility model proposes a VR ventilated mask, aiming to solve the problem of poor ventilation and light-blocking performance of existing VR masks. The VR ventilated mask includes an outer shell plate 2 and a light-blocking plate 3 spaced apart by a first ventilation gap 4. Multiple first ventilation holes 21 are formed on the outer shell plate 2, allowing air in the first ventilation gap 4 to circulate with external air. Correspondingly, a first ventilation hole 31 is formed on the light-blocking plate 3, enabling ventilation while blocking light, thus allowing air in the first ventilation gap 4 to circulate with the internal air of the VR ventilated mask. It should be noted that the aforementioned baffle can block air in the first ventilation gap, allowing air to effectively enter the first ventilation hole.

[0045] That is, based on the first vent 21, the first ventilation gap 4, and the first ventilation hole 31 connected in sequence, a corresponding first light-shielding ventilation channel can be formed. Through this first light-shielding ventilation channel, the VR ventilation mask can be ventilated inside and out, effectively improving the mask's breathability and thus effectively reducing fogging of the host lens and eyeglass lens. Moreover, since the first light-shielding ventilation channel has a stepped structure, it can effectively ensure that the frontal light shining inward through the first vent 21 is blocked by the light-blocking plate 3, thereby ensuring the mask's light-shielding performance.

[0046] Furthermore, in the VR ventilated mask of this utility model, the opening of the first vent is disposed facing the non-opening area of ​​the light-blocking plate, and the opening of the first ventilation hole is disposed facing the non-opening area of ​​the outer shell plate, so that the first ventilation hole and the first vent are offset.

[0047] In practical applications, such as Figure 10 and Figure 11 As shown, Figure 11 The solid line with an arrow indicates the path of airflow. Figure 11 The flow within the first light-blocking ventilation channel effectively ensures ventilation both inside and outside the VR ventilated mask. Due to the offset, or staggered, arrangement of the first vent hole and the first ventilation hole, their openings are not directly opposite each other. The opening of the first vent hole 21 faces the non-opening area of ​​the light-blocking plate 3, while the opening of the first ventilation hole 31 faces the non-opening area of ​​the outer shell plate 2. This ensures that light shining inward through the first vent hole is blocked by the light-blocking plate. Figure 11 The dashed line in the middle represents the line connecting the farthest point of light between the first vent and the first ventilation hole. This light is also blocked by the light-blocking plate. Therefore, the light entering from the first vent can be effectively blocked, achieving a light-blocking effect.

[0048] It should be noted that the VR ventilation mask has a vertical height direction, which approximates the front-to-back direction of the body when the VR ventilation mask is worn. The long axis of the first ventilation hole extends parallel to the vertical height direction. The size of the first ventilation hole 21 (e.g., its extension length along the vertical height direction) is adapted to the size of the outer shell plate 2. Where the area of ​​the outer shell plate 2 is larger, the extension length of the first ventilation hole 21 will increase accordingly; where the area of ​​the outer shell plate 2 is smaller, the extension length of the first ventilation hole 21 will also increase accordingly. In practical applications, the inner wall surface of the first ventilation hole 21 can be a slope for better demolding. In some embodiments, the first ventilation hole 21, viewed along its depth direction, can present a funnel shape.

[0049] Furthermore, such as Figure 14 As shown, the VR ventilated mask of this utility model also includes a first light-shielding plate 5. The first light-shielding plate 5 is disposed on the mask body 1. The first light-shielding plate 5 is located inside the light-blocking plate 3, that is, the light-blocking plate is disposed between the outer shell plate and the first light-shielding plate. There is a second ventilation gap 6 between the first light-shielding plate 5 and the light-blocking plate 3.

[0050] In practical applications, the first light-shielding plate 5 can be set to achieve the light-shielding function. For example, light from the second ventilation gap 6, the groove 11 and the second ventilation hole 22 can be blocked by the first light-shielding plate 5, thereby achieving the light-shielding effect.

[0051] Furthermore, such as Figure 18 As shown, in the VR ventilated mask of this utility model, the outer shell plate 2 has multiple second ventilation holes 22, and the bottom of the light-blocking plate 3 has a ventilation notch 32. The second ventilation holes 22, the first ventilation gap 4, the ventilation notch 32, and the second ventilation gap 6 are sequentially connected to form a second light-blocking ventilation channel. It should be noted that the ventilation notch 32 can be a notch opened at the bottom of the light-blocking plate, through which air can circulate.

[0052] In practical applications, the second vent 22 allows air in the first ventilation gap 4 to circulate with external air, and the light-blocking plate 3 can block some of the light from the second vent 22. The light-blocking plate 3 has a ventilation notch 32, and a second ventilation gap 6 exists between the light-blocking plate 3 and the first light-blocking plate 5. Through the ventilation notch 32, air can circulate between the first ventilation gap 4 and the second ventilation gap 6, while through the second ventilation gap 6, air can circulate inside the VR ventilation mask. That is, the second vent 22, the first ventilation gap 4, the ventilation notch 32, and the second ventilation gap 6 are sequentially connected to form a second light-blocking ventilation channel with a structure similar to a convex / concave shape. This second light-blocking ventilation channel enables ventilation of the VR ventilation mask from both inside and outside, effectively improving the mask's breathability and thus effectively reducing fogging of the main unit lenses and eyeglass lenses.

[0053] In practical applications, such as Figure 19 As shown, Figure 19 The solid line with an arrow indicates the path of airflow. Figure 19 The flow within the second light-shielding ventilation channel, as shown, effectively ensures ventilation and breathability both inside and outside the VR ventilated mask. For example... Figure 19 As shown, some of the light entering through the second vent can be blocked by the light-blocking plate, and some can also be blocked by the second light-blocking plate, thus achieving a light-blocking effect. Figure 19 The dotted line indicated by the arrow represents the light path corresponding to the connection line between the bottom of the second ventilation hole and the top of the first light shield. This light can be effectively blocked by the first light shield. Therefore, external light that is not blocked by the light shield can be effectively blocked by the first light shield, achieving a light-blocking effect.

[0054] Furthermore, it should be noted that in practical applications, the aforementioned first light-shielding ventilation channel structure can be installed in a location with ample space, such as... Figure 1 as well as Figure 7 As shown, it can be set on both sides of the VR ventilation mask and near the top of the VR ventilation mask. Conversely, the corresponding structure of the second light-shielding ventilation channel can be set in a more spatially limited location, such as... Figure 4 as well as Figure 7 As shown, the structure corresponding to the second light-shielding ventilation channel can be set on both sides of the nose bridge frame 7.

[0055] Furthermore, such as Figure 5 As shown, in the VR ventilation mask of this utility model, the mask body 1 has an upward-facing groove 11, and the groove 11 is correspondingly arranged with the ventilation notch 32.

[0056] As can be seen from the above description, the corresponding groove 11 is provided to facilitate air circulation between the first ventilation gap 4 and the second ventilation gap 6, thus facilitating ventilation.

[0057] Furthermore, such as Figure 3 , Figure 8 as well as Figure 12 As shown, in the VR ventilation mask of this utility model, the outer shell plate 2 is provided with a guide 25, and the light blocking plate 3 is provided with a downward-facing slot 33, wherein the guide 25 is disposed in the slot 33.

[0058] As described above, by setting the corresponding guide 25, the light-blocking plate 3 can be quickly installed through the cooperation of the slot 33 and the guide 25. Furthermore, after installation, the guide 25 can also limit the position of the light-blocking plate 3. In addition, it should be noted that the guide 25 also has a foolproof function. In practical applications, the VR ventilation mask has two light-blocking plates 3 with similar structures, making it easy to install them incorrectly. This solution, by setting corresponding guide 25s at symmetrical positions on the two outer shell plates 2, allows for accurate and quick installation of the light-blocking plate 3 onto the corresponding mask body 1 through the cooperation of the guide 25 and the slot 33, preventing misinstallation.

[0059] Furthermore, such as Figure 13 As shown, in the VR ventilated mask of this utility model, the baffle includes a first baffle and a second baffle, and the first baffle and the second baffle are located on different sides of different first vent holes.

[0060] In practical applications, the main difference between the first baffle 23 and the second baffle 24 lies in their positions relative to the first vent 21. Since the guide 25 is located in the middle of the outer casing 2, Figure 8As shown, both the first baffle 23 and the second baffle 24 are located on the side of the first vent 21 away from the guide member 25. The first baffle 23 on the left side of the guide member 25 is a left-side baffle, that is, the first baffle 23 is located to the left of the corresponding first vent 21, while the second baffle 24 on the right side of the guide member 25 is a right-side baffle, that is, the second baffle 24 is located to the right of the corresponding first vent 21.

[0061] For the two nearest left and right ribs adjacent to the guide 25, specifically: (e.g.) Figure 13 As shown, one side of the guide member 25 is a first baffle 23, and the other side is a second baffle 24. Therefore, the two closest left and right first vent holes 21 to the guide member 25 are connected to the U-shaped slot 33 through the first ventilation gap 4. This means that this solution can further utilize the U-shaped slot for ventilation and air permeability, in addition to using it for guidance and limiting. This allows the outer shell plate 2 to have more first vent holes 21, further improving the internal and external ventilation performance of the VR ventilation mask. It should be noted that the space near the opening of the U-shaped slot, through which the guide member passes, allows for air circulation. The design of the left and right baffles has the following effect: it helps to block light from different angles. Figure 8 and Figure 9 For example, when light enters from the lower left to the upper right at a large angle relative to the first vent, the light entering from the left first vent will be blocked by the light-blocking plate 2 located in the first ventilation gap 4, while the light entering from the right first vent will be blocked by the second baffle 24 of the right first vent. Conversely, when light enters from the upper right to the lower left at a large angle relative to the first vent, the light entering from the right first vent will be blocked by the light-blocking plate 2 located in the first ventilation gap 4, while the light entering from the left first vent will be blocked by the first baffle 23 of the left first vent. Therefore, the arrangement of the first and second baffles ensures that light entering at large angles from different angles can be blocked by the baffles and light-blocking plates. Light entering at smaller angles relative to the first vent is easily blocked by the baffles.

[0062] In practical applications, the two closest left and right first ventilation holes 21 adjacent to the aforementioned slot and the guide 25 can be connected through the first ventilation gap 4, thereby forming a fourth light-shielding ventilation structure, further improving the internal and external ventilation performance of the VR ventilation mask. Figure 9 As shown, Figure 9 The solid line with an arrow indicates the path of airflow. Figure 9 The flow in the fourth light-shielding ventilation channel shown can effectively ensure the ventilation of the VR ventilation mask inside and out.

[0063] Furthermore, such as Figure 15 As shown, the VR ventilated mask of this utility model also includes a connecting plate 12 and a second light-shielding plate 13 disposed on the mask body 1. The two ends of the connecting plate 12 are respectively connected to the outer shell plate 2. The connecting plate 12 is provided with a second ventilation hole 14. The second light-shielding plate 13 is located inside the connecting plate 12, and there is a third ventilation gap 15 between the second light-shielding plate 13 and the connecting plate 12.

[0064] In practical applications, the overall structure of the outer shell 2 can be an arc-shaped structure, with both ends of the arc-shaped structure connected by a connecting plate 12. A second ventilation hole 14 is provided on the connecting plate 12. Correspondingly, to block the light from the second ventilation hole 14, a second light-shielding plate 13 is designed on the inner side of the connecting plate 12. This second light-shielding plate 13 is mounted on the mask body 1. Furthermore, to ensure effective ventilation through the second ventilation hole 14, this invention also provides a third ventilation gap 15 between the second light-shielding plate 13 and the connecting plate 12. This third ventilation gap 15 and the second ventilation hole 14 together form a third light-shielding ventilation channel.

[0065] Furthermore, such as Figure 4 As shown, in the VR ventilation mask of this utility model, the outer shell plate 2 is provided with a plurality of slots 26, and the two ends of the light blocking plate 3 are respectively embedded in the slots 26.

[0066] As described above, multiple latches 26 are provided on the outer shell plate 2 to lock the light-blocking plate 3 in place and prevent it from moving. Furthermore, the provision of these latches 26 facilitates the rapid installation of the light-blocking plate 3.

[0067] Furthermore, such as Figure 4 As shown, the VR ventilated mask of this utility model also includes a nose bridge frame 7, which is disposed on the outer shell plate 2.

[0068] As described above, a nose bridge 7 is provided in the VR ventilated mask. The nose bridge 7 can fit the sides of the user's nose bridge, which can facilitate the wearing of the VR ventilated mask and effectively prevent external light from entering through the gap between the nose and the mask, reducing light leakage and thus enhancing the immersiveness of the virtual reality experience.

[0069] Furthermore, such as Figure 3 as well as Figure 12 As shown, in the VR ventilated mask of this utility model, the outer shell plate 2 is provided with a limiting block 27, and the light blocking plate 3 is provided with a limiting groove 34, wherein the limiting block 27 is disposed in the limiting groove 34.

[0070] As described above, the light-blocking plate 3 can be limited and prevented from moving by the cooperation between the limiting block 27 and the limiting groove 34. In addition, the mask body 1 can also be provided with corresponding limiting protrusions 16 to further limit the light-blocking plate 3.

[0071] In addition, in some embodiments, a corresponding light-blocking pad can be provided at the bottom where the light-blocking plate 3 contacts the mask body 1, thereby further enhancing the light-blocking effect. Of course, a corresponding fan can also be provided on the VR ventilated mask to further enhance the ventilation effect, such as by providing a corresponding fan in the first ventilation hole 21.

[0072] Please refer to Figures 1 to 19 One embodiment of this utility model is: a VR ventilated face mask, which includes a face mask body 1 and a light-blocking plate 3. For example... Figure 2 As shown, the main body 1 of the mask has an overall structure resembling a ring, with symmetrical arrangement on its left and right sides. A nose bridge 7 is located below the main body 1. The main body 1 includes an outer shell 2, which has an overall arc-shaped structure. A connecting plate 12 is provided between the two ends of the outer shell 2, connecting the two ends to form a ring structure. Two light-blocking plates 3 are also provided on the main body 1, such as... Figure 1 As shown, two light-blocking plates 3 are symmetrically arranged on the mask body 1. The two light-blocking plates 3 are located inside the outer shell plate 2, and the light-blocking plates 3 are engaged with the outer shell plate 2.

[0073] In this embodiment, as Figure 3 , Figure 4 , Figure 5 , Figure 10 as well as Figure 11 As shown, the outer shell plate 2 is provided with a plurality of first ventilation holes 21, and each first ventilation hole 21 is provided with a baffle extending toward the light-blocking plate 3 on its side. Correspondingly, there is a first ventilation gap 4 between the light-blocking plate 3 and the outer shell plate 2. The light-blocking plate 3 is provided with a plurality of first ventilation holes 31 that cooperate with the first ventilation holes 21, and the first ventilation holes 31 are offset from the first ventilation holes 21. The first ventilation holes 21, the first ventilation gap 4 and the first ventilation holes 31 are connected in sequence to form a stepped first light-blocking ventilation channel.

[0074] In this embodiment, as Figure 4 , Figure 17 , Figure 18 as well as Figure 19As shown, a nose bridge is provided at the lower part of the VR ventilated mask, and a second light-blocking and ventilation structure is provided on both sides near the nose bridge 7. Specifically, the VR ventilated mask also includes a first light-blocking plate 5 connected to the outer shell plate 2. The first light-blocking plate 5 is disposed on the mask body 1 and is located inside the light-blocking plate 3. A second ventilation gap 6 is provided between the first light-blocking plate 5 and the light-blocking plate 3. Correspondingly, a plurality of second ventilation holes 22 are provided on the outer shell plate 2, and a ventilation notch 32 is provided at the bottom of the light-blocking plate 3. The second ventilation holes, the first ventilation gap 4, the ventilation notch 32, and the second ventilation gap 6 are sequentially connected to form a second light-blocking and ventilation channel. In addition, a groove 11 is provided at the position corresponding to the ventilation notch 32 on the mask body 1 to further facilitate ventilation.

[0075] In this embodiment, as Figure 14 as well as Figure 15 As shown, a third light-shielding ventilation structure is also provided on the upper part of the VR ventilation mask. This third light-shielding ventilation structure is connected to the structure corresponding to the first light-shielding ventilation channel. The third ventilation and light-shielding structure includes a connecting plate 12 and a second light-shielding plate 13 disposed on the mask body 1. The two ends of the connecting plate 12 are respectively connected to the outer shell plate 2. The connecting plate 12 is provided with a second ventilation hole 14. The second light-shielding plate 13 is located inside the connecting plate 12, and there is a third ventilation gap 15 between the second light-shielding plate 13 and the connecting plate 12. The third light-shielding ventilation channel can be formed through the third ventilation gap 15 and the second ventilation hole 14.

[0076] In this embodiment, as Figure 3 , Figure 7 , Figure 8 as well as Figure 9 As shown, to facilitate the detachable installation of the light-blocking plate 3, a guide 25 is provided on the outer shell plate 2. The light-blocking plate 3 has a downward-facing slot 33. During installation, the guide 25 is inserted into the slot 33, which helps with accurate installation. Furthermore, to maximize the ventilation structure, the slot 33 can be used for ventilation. Therefore, the position of the baffles on the first ventilation hole 21 can be adjusted so that the first / second baffles located on the side of the first ventilation hole 21 are positioned away from the guide 25. In this case, the two closest left and right first ventilation holes 21 adjacent to the slot and the guide 25 can be connected through the first ventilation gap 4, thus forming a fourth light-blocking ventilation structure, further improving the internal and external ventilation performance of the VR ventilation mask.

[0077] In summary, by setting up the corresponding first, second, third, and fourth light-blocking ventilation channels, the VR ventilation mask of this utility model can achieve full-coverage, all-round ventilation and breathability, with a ventilation area close to half of the outer area.

[0078] In summary, the VR ventilated mask provided by this utility model opens the ventilation grille to the maximum, achieving both light blocking and a fully enclosed, all-around ventilation structure. Its ventilation area is close to half of the outer area, thereby reducing fogging of the main unit lens and the glasses lens.

[0079] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
