Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of masks, in particular to a plateau oxygen mask. Background Art
[0002] An oxygen mask, which wraps around the nose and mouth, gathers oxygen from an oxygen storage or generator around the nose and mouth, allowing for efficient oxygen absorption. Oxygen masks are widely used to provide oxygen therapy for patients experiencing breathing difficulties and hypoxia, particularly those injured at high altitudes. Due to the inherently low oxygen content at high altitudes, injuries require oxygen to reduce the burden on the body.
[0003] The inhalation or exhalation port of the commonly used oral and nasal oxygen masks is usually directly connected to the air pump, and air is continuously supplied while exhaling, which is bound to cause oxygen waste. For this reason, some people have designed to set valves in the air inlet and outlet of the mask. However, the flow rate of oxygen input is often difficult to flush the valves, and the patient's physical weakness may also make it difficult to open the valve of the exhalation port, resulting in problems such as difficulty in oxygen input and difficulty in exhausting waste gas. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the present invention proposes a plateau oxygen mask to solve the technical problem mentioned in the above background technology that it is difficult to input oxygen and discharge waste gas by adding valves at the air inlet and outlet of the mask.
[0005] In order to solve this technical problem, the technical solution adopted by the present invention is:
[0006] A plateau oxygen mask comprises a mask body, an oxygen storage bag, a connecting pipe, an air inlet cover, an air inlet baffle, an air outlet baffle assembly, a driving mechanism and a negative pressure fan assembly;
[0007] The air inlet cover is provided on one side of the cover body and is in communication with the interior of the cover body. The air inlet cover is also provided with an air inlet hole. One end of the connecting pipe is connected to the air inlet hole, and the other end is in communication with the oxygen storage bag.
[0008] The air intake baffle is slidably arranged in the air intake cover and can close the air intake hole;
[0009] The negative pressure fan assembly is arranged in the air intake cover and can absorb the oxygen in the oxygen storage bag;
[0010] An air outlet hole is provided on the other side of the cover body, and the air outlet baffle assembly is slidably provided on the cover body and can close the air outlet hole;
[0011] The driving mechanism is provided on the cover body and can drive the air inlet baffle and the air outlet baffle assembly to slide back and forth respectively;
[0012] The binding belt is arranged on the cover body.
[0013] As can be seen from the above, the air inlet and the air outlet are respectively slidably provided on the air inlet baffle and the air outlet baffle assembly, which can cover or open the air inlet and the air outlet by sliding respectively, and a driving mechanism is provided on the mask, which makes the air inlet baffle and the air outlet baffle assembly slide back and forth, that is, the air inlet and the air outlet are repeatedly opened and closed, so that the oxygen in the oxygen storage bag can be transmitted into the mask through the negative pressure fan assembly, and the exhaled waste gas can be discharged through the air outlet.
[0014] Furthermore, the driving mechanism includes a motor, a driving rod, a connecting assembly, a fixed block, a connecting ring, and a pushing block; the motor is provided on the cover body and connected to the driving rod; the fixed block is provided on the cover body, and the outer bottom surface of the connecting ring is hinged to the fixed block; the pushing block is provided with a sliding groove, one end of the connecting assembly is hinged to the driving rod, and the other end is slidably connected to the sliding groove of the pushing block, and the connecting assembly can be slidably inserted into the connecting ring; the pushing block is connected to the air inlet baffle or the air outlet baffle assembly. Through this structure, the air inlet baffle can open the air inlet for a longer time than the time it closes the air inlet, and the air outlet baffle assembly can open the air outlet for a longer time than the time it closes the air outlet.
[0015] Furthermore, the connecting assembly includes a connecting rod and a slider; one end of the connecting rod is hinged to the driving rod, and the other end is hinged to the slider. The connecting rod slides through the connecting ring, and the slider slides in the sliding groove of the push block. The connecting rod can conveniently drive the push block to slide.
[0016] Furthermore, the outlet baffle assembly includes an outlet baffle body and a connecting rod; the outlet baffle body is slidably connected to the cover body and can cover the outlet hole, and the connecting rod is provided on one side of the outlet baffle body; the two ends of the push block are respectively connected to the inlet baffle and the outlet baffle body. When the inlet baffle moves away from and opens the inlet hole, the outlet baffle moves closer to and closes the outlet hole. This structure allows a single drive mechanism to control the inlet and outlet to be opened or closed at different times.
[0017] Furthermore, the negative pressure fan assembly includes a negative pressure fan body, a wire, and a touch switch. The negative pressure fan body is located within the air intake cover and is electrically connected to the touch switch via the wire. The touch switch is located on the cover, and the air intake baffle slides away from the air intake to abut against the touch switch. This structure ensures that the negative pressure fan only operates when the air intake is open, drawing in oxygen. When the air intake is closed, the negative pressure fan also shuts down.

[0032] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.
[0033] A plateau oxygen mask comprises a mask body 1, an oxygen storage bag 2, a connecting pipe, an air inlet cover 4, an air inlet baffle 5, an air outlet baffle assembly 6, a driving mechanism 7 and a negative pressure fan assembly 8.
[0034] The air inlet cover 4 is provided on one side of the housing 1 and communicates with the interior of the housing 1. The air inlet cover 4 is also provided with an air inlet hole 11. One end of a connecting tube is connected to the air inlet hole 11, and the other end is connected to the oxygen storage bag 2. It should be understood that the inner side of the housing 1 is the side thereof that is recessed and capable of covering the human body.
[0035] The air intake baffle 5 is slidably disposed within the air intake cover 4 and is capable of sealing the air intake hole 11. It should be understood that the connecting tube connects the interior of the mask to the oxygen storage bag 2 and does not interfere with the sliding movement of the air intake baffle 5. Furthermore, the air intake cover 4 is provided with a through hole through which the air intake baffle 5 can pass, leaving only a slight gap between the air intake baffle 5 and the through hole, allowing only a very small amount of oxygen to pass through.
[0036] The negative pressure fan assembly 8 is arranged in the air intake cover 4 and can inhale the oxygen in the oxygen storage bag 2. It should be understood that the air intake baffle 5 is located between the negative pressure fan assembly 8 and the air intake hole 11.
[0037] An air outlet 12 is provided on the other side of the cover body 1, and an air outlet baffle assembly 6 is slidably provided on the cover body 1 and can close the air outlet 12. It should be understood that the air inlet 11 and the air outlet 12 are preferably not on the same side.
[0038] It should also be noted that both the air inlet baffle 5 and the air outlet baffle assembly 6 have a bottom dead center for sliding, and when located at the bottom dead center, the air inlet hole 11 or the air outlet hole 12 is closed.
[0039] The drive mechanism 7 is provided on the housing 1 and is capable of driving the air inlet baffle 5 and the air outlet baffle assembly 6 to slide back and forth, respectively. It should be understood that when a single drive mechanism 7 cannot drive the air inlet baffle 5 and the air outlet baffle assembly 6 to slide, a drive mechanism 7 should be provided corresponding to each of the air inlet baffle 5 and the air outlet baffle assembly 6, i.e., one drive mechanism 7 drives one air inlet baffle 5 to slide, and another drive mechanism 7 drives the air outlet baffle assembly 6 to slide. Furthermore, by providing the drive mechanism 7, when the air inlet baffle 5 opens the air inlet hole 11, the air outlet baffle assembly 6 closes the air outlet hole 12.
[0040] The binding belt 9 is provided on the cover body 1. The binding belt 9 can bind the cover body 1 to the human body.
[0041] The air inlet 11 and the air outlet 12 are slidably provided on the air inlet baffle 5 and the air outlet baffle assembly 6, respectively, and can cover or open the air inlet 11 and the air outlet 12 by sliding respectively, and a driving mechanism 7 is provided on the mask, and the air inlet baffle 5 and the air outlet baffle assembly 6 are slid back and forth by the driving mechanism 7, that is, the air inlet 11 and the air outlet 12 are repeatedly opened and closed, so that the oxygen in the oxygen storage bag 2 can be introduced into the mask through the negative pressure fan assembly 8, and the exhaled waste gas is discharged through the air outlet 12.
[0042] In other embodiments, the drive mechanism 7 includes a motor 71, a drive rod 72, a connecting assembly 73, a fixed block 74, a connecting ring 75, and a push block 76. The motor 71 is mounted on the housing 1 and connected to the drive rod 72. The fixed block 74 is mounted on the housing 1, and the outer bottom surface of the connecting ring 75 is hingedly connected to the fixed block 74. The push block 76 has a sliding groove. One end of the connecting assembly 73 is hingedly connected to the drive rod 72, and the other end is slidably connected to the sliding groove of the push block 76. The connecting assembly 73 is slidably inserted into the connecting ring 75. The push block 76 is connected to the air inlet baffle 5 or the air outlet baffle assembly 6. This structure allows the air inlet baffle 5 to open the air inlet for a longer time than it closes the air inlet, and the air outlet baffle assembly 6 to open the air outlet for a longer time than it closes the air outlet. It should be understood that the connecting ring 75 is vertically mounted on the top of the fixed block 74, and the connecting assembly 73 is slidably connected to the inner ring of the connecting ring 75 and can slide along the length of the connecting assembly 73. The cam 75 is rotated by the motor 71, and the cam 75 is rotated by the motor 71. When the cam 75 is rotated, the cam 75 rotates. The cam 75 passes through the cam 75 and slides in the direction of the air inlet baffle 5 or the air outlet baffle assembly 6. The end of the cam 73 that is slidably connected to the sliding groove of the push block 76 slides from one side of the sliding groove to the other side, and drives the push block 76 to slide in the direction of the air inlet baffle 5 or the air outlet baffle assembly 6, and closes the air inlet hole 11. When the drive rod 72 slides in the direction away from the air inlet plate or the air outlet baffle assembly 6, the connecting assembly 73 drives the connecting ring 75 to rotate. When the locking cam 75 is in the closed position, the locking cam 76 is in the closed position, and ...During this process, when the pushing block 76 slides to the lowest point, that is, the bottom dead center of the air inlet baffle 5 or the air outlet baffle assembly 6 that is about to open the air inlet hole 11 or the air outlet hole 12, the pushing block 76 can stay for a long time, that is, the pushing block 76 can stay for a long time after opening the air inlet hole 11 or the air outlet hole 12, and when the pushing block 76 slides toward the air inlet baffle 5 or the air outlet baffle assembly 6, the air inlet baffle 5 or the air outlet baffle assembly 6 temporarily closes the air inlet hole 11 or the air outlet hole 12. Specifically, when the air inlet baffle 5 or the air outlet baffle assembly 6 slides toward the air inlet hole 11 or the air outlet hole 12, the air inlet hole 11 or the air outlet hole 12 is first closed. As the air inlet baffle 5 or the air outlet baffle assembly 6 continues to slide, the air inlet baffle 5 assembly or the air outlet baffle assembly 6 continues to be closed until the air inlet baffle 5 or the air outlet baffle assembly 6 slides in the opposite direction and opens the air inlet hole 11 or the air outlet hole 12.
[0043] In other embodiments, the connecting assembly 73 includes a connecting rod 731 and a slider 732. One end of the connecting rod 731 is hinged to the driving rod 72, and the other end is hinged to the slider 732. The connecting rod 731 slides through the connecting ring 75, and the slider 732 slides in the sliding groove of the push block 76. The connecting rod 731 can conveniently drive the push block 76 to slide.
[0044] In other embodiments, the air outlet baffle assembly 6 includes an air outlet baffle body 61 and a connecting rod 62; the air outlet baffle body 61 is slidably connected to the cover body 1 and can block the air outlet hole 12, and the connecting rod 62 is provided on one side of the air outlet baffle body 61; the two ends of the push block 76 are respectively connected to the air inlet baffle 5 and the air outlet baffle body 61. When the air inlet baffle 5 moves away from and opens the air inlet hole 11, the air outlet baffle moves closer to and closes the air outlet hole 12. It should be understood that in this embodiment, the driving mechanism 7 is only one, and the vertical positions of the air inlet hole 11 and the air outlet hole 12 are different. When the push block 76 slides toward the air inlet cover 4, the air inlet baffle 5 and the air outlet baffle body 61 slide toward the air inlet cover 4 at the same time. Through this structure, the air inlet and the air outlet are not opened or closed at the same time, so that no new oxygen enters during exhalation, and the new oxygen that enters will not be discharged directly through the air outlet hole 12, thereby reducing oxygen waste. In this solution, when the air inlet baffle 5 is located at the bottom dead center, the air outlet baffle is located at the top dead center of the air outlet baffle itself, that is, the air outlet baffle closes the air outlet hole 12.
[0045] In other embodiments, the negative pressure fan assembly 8 includes a negative pressure fan body 81, a wire 82, and a touch switch 83; the negative pressure fan body 81 is disposed within the air intake cover 4 and is electrically connected to the touch switch 83 via the wire 82. The touch switch 83 is disposed on the cover body 1, and the air intake baffle 5 slides away from the air intake hole 11 to abut the touch switch 83. It should be understood that when the air intake baffle 5 slides to the bottom dead center and abuts the touch switch 83, the negative pressure fan body begins to operate, and when the air intake baffle 5 moves away from the touch switch 83, the negative pressure fan body stops operating. In this way, the workload of the negative pressure fan body is reduced, so that it only operates when the air intake hole 11 is open. It should also be understood that the negative pressure fan body 81 is connected to the air intake cover 4 via a connecting block, and the negative pressure fan body 81 does not drive the connecting block to move when it is in operation.
[0046] The plateau oxygen mask can control the air inlet and the air outlet respectively, so that the air inlet or the air outlet can be opened automatically, thereby reducing the occurrence of situations where the air inlet or the air outlet cannot be opened smoothly.
[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
