Description

Technical Field

[0001] The utility model relates to the technical field of gas masks, and specifically, to a gas mask. Background Art

[0002] As an important protective device, the gas mask plays a key role in many fields. However, there are some deficiencies in the existing gas masks. Since the mask usually needs to be in close contact with the skin, it is made of flexible materials. While the protective goggles are generally made of hard materials, it is difficult to achieve a stable and convenient connection when installing the two. Even for some existing integrated masks, when the protective goggles are scratched or damaged, the entire mask needs to be replaced, increasing the usage cost.

[0003] In summary, for the integrated gas mask of the protective goggles and the mask in the prior art, when the protective goggles are damaged, the whole needs to be replaced, resulting in problems such as high cost, waste of resources and inconvenience. Summary of the Utility Model

[0004] The utility model provides a gas mask, which solves the problem that the integrated gas mask of the protective goggles and the mask in the related art needs to be replaced as a whole when the protective goggles are damaged.

[0005] The technical solution of the utility model is as follows: The gas mask includes a main body, a flexible body, a lens frame and protective goggles. The main body and the lens frame are integrally arranged on the flexible body. The protective goggles are buckled on the lens frame. The top of the lens frame has a limiting strip, and the bottom has a mounting hole. The top of the protective goggles has a limiting groove, and the bottom has a mounting piece. The limiting strip is used for clamping in the limiting groove, and the mounting piece is used for inserting into the mounting hole.

[0006] Optionally, the two sides of the protective goggles have limiting plates, and the limiting plates have limiting holes. Each side of the lens frame has three limiting blocks. The middle limiting block is used for clamping the limiting hole, and the two limiting blocks on both sides are respectively used for abutting against the two side surfaces of the limiting plate.

[0007] Optionally, the lens frame has row teeth, and ventilation holes are formed between the row teeth and the protective goggles.

[0008] Optionally, it further includes an air inlet valve and an air outlet valve. The air inlet valve and the air outlet valve are both arranged on the main body. There are two air inlet valves, which are respectively located on both sides of the main body, and the air outlet valve is located in the middle of the main body.

[0009] Optionally, the air inlet valve has a connecting part. The connecting parts are multiple and are arranged circumferentially along the air inlet valve for detachably clamping with a trachea.

[0010] Optionally, the edge of the flexible body facing the face has a flexible flanging part.

[0011] Optionally, a protective cover is further included, which is buckled on the air outlet valve and has an air outlet hole.

[0012] Optionally, the air outlet holes are multiple and arc-shaped, and are evenly distributed in the circumferential direction of the protective cover.

[0013] Optionally, a clamping ring is further included, which is arranged on the protective cover. The clamping ring has a clamping ring, and the flexible body has a clamping column, which is used to clamp with the clamping ring.

[0014] Optionally, the holding ring has a rope threading portion, the rope threading portion has a plurality of rope threading holes, and the rope threading holes are used to thread elastic ropes.

[0015] The working principle and beneficial effects of the utility model are as follows:

[0016] The main body and frame are tightly integrated with the flexible body through an integrated rubber coating process. The flexible body ensures that the mask fits tightly against the skin around the eye sockets and face when worn, providing a comfortable wearing experience. When installing the protective goggles, snap them onto the frame from top to bottom. First, the limit bar at the top of the frame aligns with the limit slot at the top of the protective goggles. As the protective goggles continue to move downward, the limit bar gradually snaps into the limit slot, providing initial positioning and fixation. At the same time, the mounting tab at the bottom of the protective goggles gradually approaches the mounting hole at the bottom of the frame. Due to its inherent toughness, the mounting tab is initially squeezed and slightly deformed when it contacts the mounting hole. As the protective goggles continue to be pressed downward, the mounting tab enters the mounting hole. Once fully inserted, the mounting tab returns to its original shape, snapping into the mounting hole and firmly connecting the protective goggles to the frame.

[0017] If the protective glasses become scratched or damaged during use, or if you need to replace them with special protective glasses, simply push the mounting tab at the bottom of the protective glasses out of the mounting hole and lift the protective glasses upward to disengage the retaining bar from the retaining groove. The damaged protective glasses can then be easily removed. Then, follow the above installation steps to replace the new protective glasses.

[0018] First, by integrally setting the main body, the frame and the flexible body, the stability and tightness of the overall structure of the gas mask are ensured. The close fit between the flexible body and the skin can provide a comfortable wearing experience. Secondly, the protective goggles are detachably buckled on the frame, which greatly facilitates the replacement of the protective goggles. When the protective goggles are damaged, there is no need to replace the entire gas mask, which greatly reduces the usage cost and avoids waste of resources. At the same time, the installation process is simple and fast. The cooperative design of the limiting strip and the limiting groove, as well as the installation piece and the installation hole, makes the installation process very stable. Even during relatively intense activities, the protective goggles are not likely to fall off. In case of an emergency, the user can quickly replace the protective goggles to ensure that the protective effect is not affected, improving the practicability and reliability of the gas mask.

Detailed Embodiment

[0027] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will describe the specific embodiments of the present invention with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings, and other embodiments can also be obtained.

[0028] To make the drawings concise, only the parts related to the utility model are schematically shown in each drawing, and they do not represent the actual structure of the product. In addition, to make the drawings concise and easy to understand, in some drawings, parts with the same structure or function are only schematically shown for one of them, or only one of them is marked. In this article, "one" not only means "only this one", but also can mean "more than one" situation, and "several" includes "two" and "more than two".

[0029] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0031] Refer to Figures 1 to 6 , for the first embodiment of the present invention, a gas mask is proposed, which includes a main body 1, a flexible body 2, a frame 3 and a protective lens 4. The main body 1 and the frame 3 are integrally arranged on the flexible body 2. The protective lens 4 is buckled on the frame 3. The top of the frame 3 has a limit strip 5, and the bottom has a mounting hole 6. The top of the protective lens 4 has a limit groove 7, and the bottom has a mounting piece 8. The limit strip 5 is used for clamping in the limit groove 7, and the mounting piece 8 is used for inserting into the mounting hole 6.

[0032] In this embodiment, the main body 1 and the spectacle frame 3 are tightly and integrally combined with the flexible body 2 through an integral overmolding process. The flexible body 2 ensures that the mask can be closely attached to the skin around the eye sockets and the face during wearing, providing a comfortable wearing experience. When it is necessary to install the protective goggles 4, the protective goggles 4 are snapped onto the spectacle frame 3 from top to bottom. First, the limiting strip 5 at the top of the spectacle frame 3 is aligned with the limiting groove 7 at the top of the protective goggles 4. As the protective goggles 4 continue to move down, the limiting strip 5 gradually snaps into the limiting groove 7, playing a role in preliminary positioning and fixing. At the same time, the mounting piece 8 at the bottom of the protective goggles 4 also gradually approaches the mounting hole 6 at the bottom of the spectacle frame 3. Since the mounting piece 8 itself has toughness, it will be first squeezed and undergo a slight deformation when contacting the mounting hole 6. As the protective goggles 4 continue to be pressed down, the mounting piece 8 enters the mounting hole 6. After completely entering, the mounting piece 8 returns to its original shape, thus being stuck in the mounting hole 6, realizing the firm connection between the protective goggles 4 and the spectacle frame 3.

[0033] When the protective goggles 4 are scratched or damaged during use, or when it is necessary to replace the protective goggles 4 with other special performance ones, just push the mounting piece 8 at the bottom of the protective goggles 4 out of the mounting hole 6 with force, and at the same time lift the protective goggles 4 upward to disengage the limiting strip 5 from the limiting groove 7, then the damaged protective goggles 4 can be easily removed. Then replace the new protective goggles 4 according to the above installation steps.

[0034] First, by integrally setting the main body 1, the spectacle frame 3 and the flexible body 2, the stability and sealing performance of the overall structure of the mask are ensured. The close fit of the flexible body 2 with the skin can provide a comfortable wearing experience. Secondly, the protective goggles 4 are detachably snapped onto the spectacle frame 3, which greatly facilitates the replacement of the protective goggles 4. When the protective goggles 4 are damaged, there is no need to replace the entire gas mask, which greatly reduces the use cost and avoids waste of resources. At the same time, the installation process is simple and fast. The cooperative design of the limiting strip 5 and the limiting groove 7 and the mounting piece 8 and the mounting hole 6 makes the installation process very stable. Even during relatively strenuous activities, the protective goggles 4 are not easily detached. In case of emergency, the user can quickly replace the protective goggles 4 to ensure that the protective effect is not affected, improving the practicability and reliability of the gas mask.

[0035] Furthermore, both sides of the protective goggles 4 are provided with limiting plates 9, and the limiting plates 9 are provided with limiting holes 10. Each side of the spectacle frame 3 is provided with three limiting blocks 11. The limiting block 11 in the middle is used for clamping the limiting hole 10, and the two limiting blocks 11 on both sides are respectively used for abutting against the two side surfaces of the limiting plate 9.

[0036] In this embodiment, during the use of the gas mask, when the protective goggles 4 are installed on the frame 3, the limiting plates 9 on both sides of the protective goggles 4 play a role in further strengthening. First, move the protective goggles 4 closer to the frame 3 from top to bottom. While the limiting strip 5 is fitted with the limiting groove 7 and the mounting piece 8 is fitted with the mounting hole 6, the limiting plates 9 on both sides of the protective goggles 4 also gradually approach the limiting blocks 11 on both sides of the frame 3. When the protective goggles 4 are installed in place, the limiting blocks 11 located in the middle of both sides of the frame 3 accurately snap into the limiting holes 10 on the limiting plates 9, and the two limiting blocks 11 located on both sides tightly abut against the two side surfaces of the limiting plates 9. Such a design effectively fixes the protective goggles 4 in all directions, greatly improving the connection stability between the protective goggles 4 and the frame 3.

[0037] When it is necessary to disassemble the protective goggles 4, push the mounting piece 8 at the bottom of the protective goggles 4 out of the mounting hole 6 with force. While lifting the protective goggles 4 upward to disengage the limiting strip 5 from the limiting groove 7, the limiting blocks 11 on both sides of the frame 3 also separate from the limiting plates 9, so that the protective goggles 4 can be smoothly removed.

[0038] This design further enhances the connection stability and reliability between the protective goggles 4 and the frame 3. By providing the limiting plates 9 on both sides of the protective goggles 4 and cooperating with the limiting blocks 11 on both sides of the frame 3, the protective goggles 4 are not prone to shaking or displacement even under external force impact or during strenuous activities. In actual use, it can better ensure the accurate position of the protective goggles 4, ensure the clear vision of the user, and improve the protection effect of the gas mask. At the same time, this multi-directional fixing method also enables the gas mask to maintain good performance in various complex environments, providing more secure and reliable protection for the user.

[0039] Furthermore, the frame 3 is provided with row teeth 12, and ventilation holes 13 are formed between the row teeth 12 and the protective goggles 4.

[0040] In this embodiment, ventilation holes 13 are formed between the row teeth 12 on the frame 3 and the protective goggles 4. When the user wears the gas mask, air can circulate through these ventilation holes 13, thereby improving the wearing comfort. In the actual use process, when the temperature difference between indoors and outdoors is too large, if there is no good air permeability, water vapor may accumulate and fog up on the protective goggles 4, affecting the vision. The existence of the ventilation holes 13 can effectively discharge the water vapor and keep the inside of the protective goggles 4 dry.

[0041] When cleaning the gas mask, these ventilation holes 13 also play a role in facilitating water drainage. After cleaning the gas mask, the water can directly pass through the ventilation holes 13 and be quickly discharged, avoiding the accumulation of water between the frame 3 and the protective goggles 4, so that the cleaned gas mask can dry faster and be convenient for the next use.

[0042] First, the ventilation holes 13 formed between the row of teeth 12 and the protective goggles 4 greatly improve the breathability of the gas mask, so that the user will not feel stuffy and uncomfortable during wearing. Especially during long-term use, it can significantly improve the user experience. Secondly, the ventilation holes 13 are convenient for draining water during cleaning, which helps to keep the gas mask clean and hygienic, and extends the service life of the gas mask. At the same time, the good breathability and water drainage performance also reduce the impact on the protective performance of the gas mask caused by water accumulation, ensuring that the gas mask can play a reliable protective role in various situations.

[0043] Furthermore, it also includes an intake valve 14 and an exhaust valve 15. The intake valve 14 and the exhaust valve 15 are both arranged on the main body 1. There are two intake valves 14, which are respectively located on both sides of the main body 1, and the exhaust valve 15 is located in the middle of the main body 1.

[0044] Furthermore, the intake valve 14 has a connecting part 16. The connecting parts 16 are multiple and are arranged circumferentially along the intake valve 14 for detachably clamping with the trachea.

[0045] In this embodiment, during the actual use of the gas mask, the intake valve 14 and the exhaust valve 15 play important roles. Both the intake valve 14 and the exhaust valve 15 are one-way valves. The two intake valves 14 on the main body 1 are respectively located on both sides. When the user wears the gas mask to breathe, the external air enters the mask interior through these two intake valves 14. The connecting parts 16 on the intake valve 14 are arranged circumferentially along the intake valve 14. When it is necessary to connect the trachea for air supply, the trachea can be detachably clamped with the connecting part 16, and a part corresponding to the connecting part 16 can be designed on the trachea.

[0046] The exhaust valve 15 located in the middle of the main body 1 is responsible for discharging the gas exhaled by the user out of the mask. Such a design ensures the air circulation, and the user can breathe smoothly when wearing the gas mask.

[0047] On the one hand, setting two intake valves 14 and one exhaust valve 15 reasonably arranges the air inlet and outlet channels, ensures the effective air circulation, and improves the breathing comfort of the user. On the other hand, the connecting part 16 on the intake valve 14 enables the gas mask to be flexibly connected to the trachea according to different usage requirements, expanding the applicable range of the gas mask. The design of detachable clamping facilitates the operation, and can be quickly switched in the cases of needing and not needing to connect the trachea, improving the practicality and convenience of the gas mask.

[0048] Furthermore, the edge of the flexible body 2 facing the face side has a flexible flanging part 17.

[0049] In this embodiment, the flexible body 2 has a flexible flanging portion 17 on the edge facing the face. When the user wears the gas mask, the flexible flanging portion 17 can come into contact with the skin more fully. Due to its soft characteristics, it can better fit the contour of the face, especially in areas such as the cheeks and chin at the edge of the face. During the wearing process, the flexible flanging portion 17 will deform slightly according to the shape of the face, so as to ensure that there is no gap between it and the skin.

[0050] For example, when the user makes some head movements or facial expression changes, the flexible flanging portion 17 can always maintain close contact with the skin and will not become loose or have gaps due to the movements. Even in a relatively harsh environment, such as when encountering strong winds or vibrations, the flexible flanging portion 17 can effectively block harmful substances from the outside from entering the mask interior.

[0051] First of all, the presence of the flexible flanging portion 17 greatly improves the tightness of the contact between the gas mask and the skin. This enables the gas mask to better play its protective role and effectively prevent harmful gases, dust and other substances from entering from the edge of the face. Secondly, the soft material makes the user more comfortable during the wearing process and will not cause compression or discomfort to the skin. At the same time, the good tightness also reduces the possibility of air leakage and improves the safety of breathing. Finally, this design enhances the stability of the gas mask and ensures reliable protective effects in various usage scenarios.

[0052] Furthermore, it further includes a protective cover 18, the protective cover 18 is buckled on the air outlet valve 15, and the protective cover 18 has air outlet holes 19.

[0053] Furthermore, the air outlet holes 19 are multiple and arc-shaped, and are evenly distributed in the circumferential direction of the protective cover 18.

[0054] In this embodiment, the protective cover 18 is buckled on the air outlet valve 15 and plays an important protective role. When the gas mask is in different usage environments, it may face various potential risks of collision or scratching. The protective cover 18 can effectively block the direct impact of external objects on the air outlet valve 15 and prevent the air outlet valve 15 from being damaged. At the same time, the protective cover 18 has multiple arc-shaped air outlet holes 19, and these air outlet holes 19 are evenly distributed in the circumferential direction of the protective cover 18. When the user exhales, the gas is discharged from the air outlet valve 15 and then released to the external environment through the air outlet holes 19 on the protective cover 18. Since the air outlet holes 19 are arc-shaped and evenly distributed in the circumferential direction, on the premise of ensuring gas circulation, the protective cover 18 covers the air outlet area of the air outlet valve 15, and there will be no local blockage or poor air flow.

[0055] The setting of the protective cover 18 greatly improves the safety of the air outlet valve 15 and extends the service life of the gas mask. The arc-shaped air outlet holes 19 evenly distributed in the circumferential direction ensure the gas flow and effectively protect the air outlet valve 15, enabling the gas mask to stably play a protective role in various complex environments. This design improves the reliability and practicality of the gas mask, providing a safer and more comfortable protective experience for users.

[0056] Further, it also includes a clamping ring 20. The clamping ring 20 is arranged on the protective cover 18. The clamping ring 20 has a snap ring 21, and the flexible body 2 has a clamping post 22. The clamping post 22 is used for clamping with the snap ring 21.

[0057] In this embodiment, when the protective cover 18 needs to be installed, the protective cover 18 is buckled on the air outlet valve 15. At this time, the snap ring 21 on the clamping ring 20 corresponds to the clamping post 22 on the flexible body 2. Then, by gently pressing the clamping ring 20, the clamping post 22 is snapped into the snap ring 21 to realize the firm connection of the protective cover 18, the clamping ring 20 and the flexible body 2.

[0058] When the user wears the gas mask and moves, the clamping ring 20 can ensure that the protective cover 18 will not fall off due to shaking or accidental collision. Even in a relatively strenuous exercise or a complex working environment, the protective cover 18 can always stably protect the air outlet valve 15. When the protective cover 18 needs to be disassembled for cleaning or replacement, just pull the clamping post 22 out of the snap ring 21 with force, and the protective cover 18 can be easily removed. This clamping method is simple and convenient to operate, facilitating the user to maintain and service the gas mask in different situations.

[0059] Further, the clamping ring 20 has a rope-passing part 23, and the rope-passing part 23 has a number of rope-passing holes 24 for passing through an elastic rope.

[0060] In this embodiment, when in use, first pass the elastic rope through a number of rope-passing holes 24 on the rope-passing part 23 in sequence. Then, the user wears the gas mask on the face. After adjusting the position, put the elastic rope on the head. At this time, the elastic rope is in a stretched state, generating a pulling force towards the head direction. This pulling force is transmitted to the clamping ring 20, causing the clamping ring 20 to squeeze the flexible body 2.

[0061] Since the flexible body 2 has a certain elasticity, under the squeezing action of the clamping ring 20, the flexible body 2 fits more closely to the user's face. Especially at the edge contact part between the gas mask and the face, the flexible body 2 can fully adapt to different facial contours to ensure there are no gaps. For example, when the user makes some movements, such as turning the head or lowering the head, the pulling force of the elastic rope always acts on the clamping ring 20, keeping the flexible body 2 in close contact with the face.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
