An improved breathing mask

Abstract

This utility model provides an improved breathing mask, including an outer shell and a flexible body. The outer shell has a bowl-shaped structure with a mounting part corresponding to its opening. The flexible body is an elastic annular geometric body for fitting snugly over the user's mouth and nose. The flexible body has a fitting part that engages with the mounting part. The fitting part is configured to maintain its elasticity and adhere to the mounting part after tensile deformation, allowing the flexible body to be quickly and securely installed onto the outer shell. The geometric assembly of the fitting part of the flexible body and the mounting part of the outer shell significantly shortens the assembly time. Furthermore, the fitting part retains its elasticity after tensile deformation, ensuring that the flexible seal remains tightly against the mounting part under facial movement or external force interference, improving connection reliability and sealing performance.

Description

Technical Field

[0001] This utility model relates to the field of respiratory mask technology, and more specifically, to an improved respiratory mask. Background Technology

[0002] Breathing masks, as medical auxiliary devices, are generally used in combination with nebulizers and are commonly used for nebulization therapy. Currently available breathing masks consist of a rigid outer shell as a supporting frame, combined with a flexible sealing component, typically made of silicone or thermoplastic elastomer, as the fitting part. The two components need to work reliably together to ensure a proper seal between the mask and the wearer's mouth and nose, as well as to provide comfort.

[0003] However, the existing methods of fixing flexible seals to the shell, such as snap-fit ​​or adhesive, involve many assembly steps and are complicated to operate. Especially when the strength or elasticity of the connection between the flexible seal and the shell is insufficient, misalignment or loosening can easily occur, leading to a decrease in sealing performance or even detachment. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an improved breathing mask to solve the above problems.

[0005] The present invention adopts the following solution:

[0006] This application provides an improved breathing mask, including an outer shell and a flexible body; the outer shell has a bowl-shaped structure with a mounting part corresponding to its opening; the flexible body is an elastic annular geometric body for fitting snugly over the user's mouth and nose; the flexible body has a fitting part that engages with the mounting part, the fitting part being configured to remain elastically attached to the mounting part after tensile deformation, so that the flexible body can be quickly and securely installed onto the outer shell.

[0007] As a further improvement, the mounting part has a corresponding rib structure, the fitting part has a corresponding groove structure, and the outer diameter of the mounting part is larger than the outer diameter of the fitting part.

[0008] As a further improvement, the mounting portion extends outward in a horizontal direction relative to the opening, and the fitting portion is opened on the inner circle of the annular geometry.

[0009] As a further improvement, the fitting portion protrudes relative to the inner surface of the flexible body to form an arc-shaped surface with an R-angle transition, the arc-shaped surface being adapted to fit around the user's mouth and nose.

[0010] As a further improvement, a snap-fit ​​point is provided at the opening of the outer shell, which corresponds to the separation of the mounting part, and the fitting part is adapted to be sleeved onto the corresponding mounting part after being pulled along the separation.

[0011] As a further improvement, at least three snap-fit ​​points are provided, arranged in a triangular shape on the upper side and the lower sides of the opening, thereby dividing the mounting part into three mounting sections.

[0012] As a further improvement, the flexible body corresponds to the snap-fit ​​point to form a matching snap-fit ​​groove, and the fitting part corresponds to the groove segment that is separated by the snap-fit ​​groove and matches the corresponding mounting section.

[0013] As a further improvement, the length of the groove segment is smaller than the length of the mounting segment to which it belongs, so that the groove segment can maintain elastic fit into the mounting segment after being stretched and deformed.

[0014] As a further improvement, a cavity is formed between the flexible body and the outer shell, the outer shell is provided with a pipe hole communicating with the cavity at its opening, and the flexible part is provided with an opening communicating with the cavity at the user's mouth and nose.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] The improved breathing mask of this application uses a geometric assembly where the fitting part of the flexible body and the mounting part of the outer shell interlock. This allows for a quick and easy connection without the need for additional tools or fastening, significantly reducing assembly time. Furthermore, the fitting part retains its elasticity after being stretched or deformed. This ensures that the flexible seal remains tightly against the mounting part under facial movement or external force, improving connection reliability and sealing performance. On the other hand, users only need to apply force in a specified direction to fit the fitting part into the mounting part without damaging the components, enabling quick disassembly and replacement of the flexible seal and reducing maintenance costs.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0024] Example

[0025] Combination Figures 1 to 5 This embodiment provides an improved breathing mask, including an outer shell 1 and a flexible body 2. The outer shell 1 has a bowl-shaped structure with a mounting part 3 corresponding to its opening. The flexible body 2 is an elastic annular geometric shape for fitting snugly over the user's mouth and nose. The flexible body 2 has a fitting part 4 that engages with the mounting part 3. The fitting part 4 is configured to remain elastically attached to the mounting part 3 after tensile deformation, so that the flexible body 2 can be quickly and securely installed onto the outer shell 1.

[0026] The improved breathing mask described above uses a geometric assembly where the fitting part 4 of the flexible body 2 and the mounting part 3 of the outer shell 1 interlock. This allows for a quick and easy connection without the need for additional tools or fastening, significantly reducing assembly time. Furthermore, the fitting part 4 retains its elasticity after being stretched or deformed. This ensures that the flexible seal remains tightly attached to the mounting part 3 even under facial movement or external force interference, improving connection reliability and sealing performance. On the other hand, users only need to apply force in a specified direction to fit the fitting part 4 into the mounting part 3 without damaging the components, enabling quick disassembly and replacement of the flexible seal and reducing maintenance costs.

[0027] like Figure 2As shown, in this embodiment, the mounting part 3 has a convex rib structure, and the fitting part 4 has a groove structure, with the outer diameter of the mounting part 3 being larger than the outer diameter of the fitting part 4. Through the cooperation of the convex rib structure and the groove structure, the fitting part 4 of the flexible body 2, after being inserted into the mounting part 3 of the outer shell 1, forms a mechanical interference similar to a "locking tenon." Since the outer diameter of the mounting part 3 is slightly larger than the outer diameter of the fitting part 4, a pre-compression fitting force is generated, enabling elastic self-locking without external force, preventing accidental detachment. Furthermore, when the mask is pulled during wear, the convex rib, after being inserted into the groove, bears shear force on its lateral wall, allowing the connection to withstand the load through geometric locking rather than material adhesion, significantly improving its anti-pull-out performance.

[0028] Specifically, the mounting portion 3 extends horizontally outward relative to the opening, and the fitting portion 4 is formed on the inner ring of the annular geometry. This causes the mounting portion 3 to form a flange on the periphery of the opening, creating a snap-fit ​​structure that facilitates installation guidance and ensures that the flexible body 2 can be smoothly fitted into it during assembly. The fitting portion 4, located on the inner ring of the annular geometry, can automatically conform to the outer ring of the opening, achieving quick and precise alignment without requiring additional correction.

[0029] Furthermore, the fitting portion 4 protrudes from the inner surface of the flexible body 2 to form an arc-shaped surface 5 with a rounded angle transition. This arc-shaped surface 5 is adapted to fit around the user's mouth and nose. Clearly, the arc-shaped surface 5 with its rounded angle transition matches the curve of the facial contours, allowing for a better fit and reducing gaps, thereby improving sealing performance and reducing the risk of side leakage. Moreover, since the fitting portion 4 remains elastically attached to the mounting portion 3 after tensile deformation, it does not need to adapt to the rib structure, resulting in a right-angled protrusion of the arc-shaped surface 5. This greatly improves fitting comfort while ensuring a tight fit after assembly.

[0030] like Figure 2 and Figure 3 As shown, in this embodiment, a snap-fit ​​point 6 is provided at the opening of the outer shell 1. The snap-fit ​​point 6 correspondingly separates the mounting part 3, and the fitting part 4 is adapted to be pulled and fitted onto the corresponding mounting part 3 along the separation. On one hand, the snap-fit ​​point 6 is used to form the connection part of the strap, which facilitates the wearing of the mask. On the other hand, the multiple mounting parts 3 separated from each other and their respective fitting parts 4 are tightly and elastically attached together in multiple groups, further improving the overall connection tightness and coordination.

[0031] The device includes at least three locking points 6 arranged in a triangular shape on the upper and lower sides of the mouthpiece, thus dividing the mounting section 3 into three mounting segments 7. Clearly, the triangularly arranged locking points 6 form a stable three-point support system, which, after assembly, evenly distributes the airflow pressure and external force disturbances borne by the mask on the face, preventing concentrated force on one side that could lead to seal failure or detachment. Furthermore, the three segmented locking points 6 serve as mutual positioning references, forming an irreversible geometric lock to prevent the flexible body 2 from rotating or tilting around its central axis during use, ensuring the mask always maintains the correct installation orientation and sealing position.

[0032] The flexible body 2 corresponds to the snap-fit ​​point 6 to form a matching snap-fit ​​groove 8, and the fitting part 4 is divided by the snap-fit ​​groove 8 to form a groove segment 9 that mates with its corresponding mounting section 7. The mounting part 3 is divided into three independent sections, each of which can be elastically deformed and locked independently. Correspondingly, the flexible body 2 is divided into multiple groove segments 9 that correspond one-to-one with each mounting section 7, so that the fitting part 4 automatically aligns during assembly. Each groove segment 9 fits perfectly into the corresponding mounting section 7, eliminating alignment errors. Moreover, each groove segment 9 independently bears the pull-out force, and the pull force is distributed to the corresponding mounting section 7 through multiple groove segments 9, avoiding stress concentration that could cause tearing or failure in a single area, thus improving overall durability.

[0033] Preferably, the length of the groove segment 9 is smaller than the length of the mounting segment 7, so that the groove segment 9 remains elastically fitted into the mounting segment 7 after being stretched and deformed. Thus, the groove segment 9 is slightly shorter than the mounting segment 7, and is in a state of tensile stress after the initial fitting, generating a continuous elastic force to ensure that the groove segment 9 remains tightly pressed against the mounting segment 7 throughout the entire use process, without coming loose.

[0034] like Figure 2 and Figure 4 As shown, in this embodiment, a cavity is formed between the flexible body 2 and the outer shell 1. The outer shell 1 is provided with a pipe hole 10 communicating with the cavity at its opening. The flexible part is provided with an opening 11 communicating with the cavity at the user's mouth and nose.

[0035] The cavity, as an intermediate air chamber, allows the incoming clean airflow to be buffered and evenly distributed within the cavity, preventing the airflow from directly impacting the mouth and nose, and improving the stability and comfort of breathing.

[0036] The rational layout of the cavity, opening 11, and connecting pipe hole 10 ensures that external air or atomizing tube enters the cavity through the connecting pipe hole 10 and is then evenly delivered to the user's mouth and nose through the opening 11 of the flexible body 2. This not only optimizes airflow and breathing experience but also provides a flexible interface for the integration of external air source, filtration, and exhaust functions, balancing protective performance with user comfort.

[0037] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
