Description

Technical Field

[0001] This utility model relates to the field of respiratory equipment technology, and in particular to an oxygen storage mask. Background Technology

[0002] An oxygen-storage mask is a device that transfers oxygen from a storage tank to the lungs. There are various types, including medical oxygen-storage masks and civilian aviation oxygen-storage masks, which play an important role in assisting in the treatment of diseases and protecting the safety of flight attendants.

[0003] Existing medical oxygen storage masks include a shell, an oxygen tube connected to the shell, a ventilation hole on the shell, and a valve located on the surface of the shell at the ventilation hole. The center of the valve is connected to the shell. When the patient exhales, the airflow touches the side of the valve and rises to separate from the ventilation hole, thereby expelling air. When inhaling, the valve returns to its original position and closes the ventilation hole, which can prevent outside air from entering the mask through the ventilation hole and avoid outside air from entering the shell and affecting the oxygen concentration input from the oxygen tube.

[0004] However, the existing gas-storage masks have a drawback: the valves are prone to leaking air due to abnormal tilting, causing outside air to enter the mask when inhaling, which affects the mask's effectiveness and the user's experience. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a gas-storing mask that solves the problem of poor performance of existing gas-storing masks.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an oxygen storage mask, including a shell, a ventilation hole on the shell, a flap at the ventilation hole, at least two connecting parts on the side spacer ring of the flap, and a mating part corresponding to the connecting part on the periphery of the ventilation hole on the surface of the shell, the flap being movably fitted to the ventilation hole by engaging with the connecting part and the mating part.

[0007] Furthermore, the connecting part and the mating part can be detachably connected.

[0008] By adopting the above technical solution and the detachable connection design, it is easy to replace and remove the oxidized valve as needed, thereby reducing the maintenance cost of the product in the later stage.

[0009] Furthermore, the connecting part includes a connecting ear integrally formed with the valve, and the connecting ear is provided with a mounting hole. The mating part includes a spherical protrusion on the housing, and the spherical protrusion and the mounting hole form an insertion fit.

[0010] By adopting the above technical solution, the above design facilitates the assembly and disassembly of the valve and the housing.

[0011] Furthermore, there are two connecting parts, which are symmetrically arranged on the side of the valve with the center of the valve as the symmetrical point.

[0012] By adopting the above technical solution and setting two connection points on the valve and the shell, the connection stability between the valve and the shell can be guaranteed, and the valve can be raised or lowered normally under the action of airflow.

[0013] Furthermore, the ventilation holes are arranged in a ring at intervals on the casing.

[0014] By adopting the above technical solution, the ventilation holes arranged in the interval ring facilitate airflow and also make it easy to adapt to the shape of the valve.

[0015] Furthermore, the valve has reinforcing ribs on its side to help it return to its original position if it tilts up relative to the ventilation hole.

[0016] By adopting the above technical solution and the design of the reinforcing rib, the elasticity of the valve itself can be utilized to facilitate the valve's return to its original position after it has been raised.

[0017] Furthermore, multiple reinforcing ribs are arranged radially along the valve, with the multiple reinforcing ribs arranged circumferentially around the valve.

[0018] By adopting the above technical solution, the reinforcing ribs are arranged radially along the valve, which helps to increase the length between the valve side and the valve center, thereby increasing the lever arm length and ensuring that the valve side can smoothly tilt up or return to its original position under the action of airflow. The design of multiple reinforcing ribs helps to keep the elastic return force of each part of the valve uniform.

[0019] Furthermore, the reinforcing ribs and valves are integrally molded.

[0020] By adopting the above technical solutions, one-piece molding and processing are relatively convenient.

[0021] Compared with the prior art, the advantages of this utility model are:

[0022] 1. In this utility model, the valve is connected to the housing by a connecting part arranged at intervals on the side. Compared with the existing valve that is connected to the housing by the center point, this valve is connected to the housing by the side. This can effectively avoid the mask from leaking due to abnormal tilting of the side of the valve. When the patient inhales, the valve can stably reset and block the ventilation hole, which can effectively improve the practicality and safety stability of the mask.

[0023] 2. A major reason for valve leakage is that, because the shape of the oxygen storage mask is designed to fit the human face, and the shell of the oxygen storage mask is mostly curved, the multiple ventilation holes on the oxygen mask naturally form a curved surface. The valve is connected to the shell at the center point and the ventilation holes are blocked by the side, which easily results in gaps between the side of the valve and the ventilation holes. Therefore, this application adopts a method of connecting the side of the valve to the shell, which can stably and tightly fit the valve to the ventilation hole. This ensures that the valve can be raised normally during exhalation and can be reset normally during inhalation. The modification to the product is simple, the manufacturing cost is relatively low, and both economy and practicality are improved. Attached Figure Description

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] Reference Figure 1 The oxygen storage mask includes a housing 100, on which a ventilation hole 210 is provided. A valve 300 is provided at the ventilation hole 210. At least two connecting parts 310 are provided at equal intervals on the side of the valve 300. The periphery of the ventilation hole 210 is provided on the surface of the housing 100 with a mating part 110 corresponding to the connecting part 310. The valve 300 is movably fitted at the ventilation hole 210 by engaging with the mating part 110 through the connecting part 310. In this way, the traditional method of connecting the valve 300 and the housing 100 through the center point is replaced by connecting the side of the valve 300 to the housing 100. This can effectively avoid the mask leakage caused by the abnormal tilting of the side of the valve 300. When the patient inhales, the valve 300 can stably reset and block the ventilation hole 210, which can effectively improve the practicality and safety stability of the mask.

[0034] Reference Figure 2 Ventilation holes 210 are arranged in a ring at intervals on the housing 100. Of course, the ventilation holes 210 can also be arranged in a rectangle or other shapes. The shape of the valve 300 is adapted to the arrangement of the ventilation holes 210 so that the valve 300 can cover and close the ventilation holes 210. The following descriptions of each embodiment are based on the example of the ventilation holes 210 being arranged in a ring.

[0035] In this embodiment, since the shape of the oxygen storage mask is adapted to the human face, and the shell 100 of the gas storage mask is mostly curved, the ventilation holes 210 can be directly opened on the shell 100, or the existing common setting method can be adopted, that is, a through hole is preset on the shell 100, and then the rubber base 200 is embedded in the through hole, while the circumferential ventilation holes 210 can be set on the base 200. This method utilizes the properties of rubber material to improve the sealing of the connection between the rubber base 200 and the rubber valve 300 when they are in contact.

[0036] In this embodiment, the way the side of the valve 300 is connected to the housing 100 can stably tension the valve 300 at the ventilation hole 210, which can ensure that the valve 300 can be raised normally during exhalation and can be reset normally when the patient inhales. The stability of the valve 300 fixed on the housing 100 is also better.

[0037] In this embodiment, the number of connecting parts 310 and mating parts 110 are corresponding, and they are preferably connected in a detachable combination manner so that the valve 300 and the housing 100 can be replaced.

[0038] In this embodiment, the connecting part 310 can be set to two, three or more. As long as there is a gap between two adjacent connecting parts 310 and the position of the ventilation hole 210 corresponds to the valve 300, and the valve 300 can be raised normally when the patient exhales, the connecting part 310 can also be other numbers. In this embodiment, two connecting parts 310 are used as an example. The two connecting parts 310 are symmetrically arranged on both sides of the valve 300 with the center of the valve 300 as the symmetrical point. This can ensure the stability of the valve 300 and the shell 100, and also ensure that the valve 300 can be raised or reset normally under the action of airflow.

[0039] As an embodiment in which the connecting part 310 and the mating part 110 are detachably connected, see... Figure 2The connecting part 310 includes a connecting ear integrally formed with the valve 300. Since the valve 300 is mostly made of elastic rubber, the integrally formed connecting part 310 effectively improves the connection stability and flexibility between the connecting part 310 and the valve 300, which facilitates the production and subsequent use of the valve 300. The connecting ear is provided with a mounting hole 311. The mating part 110 includes a spherical protrusion on the housing 100. The spherical protrusion and the mounting hole 311 form a plug-in fit. In this way, by the spherical protrusion passing through the mounting hole 311, the valve 300 and the housing 100 can be easily combined together. This method makes the disassembly of the valve 300 simpler.

[0040] As another embodiment of the detachable connection between the connecting part 310 and the mating part 110, the connecting part 310 and the mating part 110 can also be connected by Velcro, screw and screw hole, or buckle and slot. Since there are many other detachable methods, they will not be described in detail here.

[0041] Based on the above embodiments, in order to further improve the stability of the rubber valve 300 in properly resetting and blocking the ventilation hole 210 when the patient inhales, a reinforcing rib 320 is provided on the side of the valve 300 away from the ventilation hole 210. By providing the reinforcing rib 320, the resetting force of the valve 300 after deformation and tilting can be improved. Thus, when the patient inhales, the valve 300 can be properly tilted or reset by utilizing the airflow and the elastic force of the valve 300 itself.

[0042] Reference Figure 3 and 4 The reinforcing ribs 320 are arranged radially along the valve 300, and multiple reinforcing ribs 320 are arranged circumferentially around the valve 300. The radial arrangement of the reinforcing ribs 320 helps to increase the length between the side of the valve 300 and the center of the valve 300, thereby increasing the lever arm length and ensuring that the side of the valve 300 can smoothly tilt up or return to its original position under the action of airflow. The design of multiple reinforcing ribs 320 also helps to keep the elastic return force of each part of the valve 300 uniform.

[0043] Furthermore, the reinforcing rib 320 and the valve 300 are integrally molded, which helps to process the reinforcing rib 320 at the same time when the rubber valve 300 is blow-molded or die-cast, thereby reducing production steps. Of course, the reinforcing rib can also be connected to the valve 300 by detachable methods such as bonding.

[0044] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
