Description

Technical Field

[0001] This utility model belongs to the technical field of respiratory protection devices, and specifically relates to a low-resistance respiratory regulator. Background Technology

[0002] A breathing regulator is used to control the flow rate or pressure of a gas (oxygen). It typically has an inlet for receiving the fluid, an outlet for providing the fluid, and a sensing element or membrane for measuring and regulating the pressure in the fluid.

[0003] Currently, most respiratory regulators in the medical device field are diaphragm regulators. When the diaphragm in the regulator comes into contact with air, a pressure difference is generated inside and outside, which pushes the diaphragm to move. However, current respiratory regulators have relatively high oxygen intake resistance, resulting in a poor oxygen intake experience, and the diaphragm has a short lifespan and is prone to rupture after repeated use. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a low-resistance breathing regulator that can adaptively switch on and off times based on the user's breathing movements and frequency, thereby conserving oxygen and extending the oxygen supply time.

[0005] This utility model is achieved through the following technical solution: A low-resistance breathing regulator includes a bottom shell, a top shell, a sealing cap, a connecting rod, a soft rubber diaphragm, and a soft rubber valve. The bottom shell has an air inlet pipe on its side and a buffer air passage and a replenishing air passage inside the bottom shell. The buffer air passage and the replenishing air passage are arranged adjacent to each other. The top of the buffer air passage is provided with a soft rubber valve plate, and the top of the replenishing air passage is provided with a limiting groove for placing a soft rubber diaphragm. The top shell is fitted onto the top of the bottom shell, and the top of the top shell is provided with an air outlet pipe that connects to its interior. The sealing cap is fixed with a support base on its side. There are two support bases arranged in parallel. The top of the support base has a through hole through its main body. The bottom of the support base is fixed with a small sealing cap. The small sealing cap has a buffer air hole through its main body in the middle. The sealing cap and the small sealing cap are respectively matched with the top of the air supply channel and the buffer air channel. The soft rubber film has a thin film in the middle, and the thin film is connected to the inner side of the soft rubber film through an annular inclined surface to form a groove; The soft rubber valve plate has a hollowed-out center and a thin valve plate connected to it. The diameter of the soft rubber valve plate matches the diameter of the top of the buffer air passage, and the diameter of the thin valve plate is larger than the diameter of the buffer air hole. Both the soft rubber diaphragm and the soft rubber valve plate are made of medical-grade materials; The connecting rod has a rotating hole in the middle for connecting a rotating rod. The rotating rod is sleeved in the through hole of the support base, so that the connecting rod is located in the middle of the two support bases. One end of the connecting rod is connected to a top rod, and the other end is connected to a pressure plate. The top rod is placed in the buffer air hole and located above the thin valve plate. The diameter of the top rod is smaller than the diameter of the buffer air hole. The pressure plate is placed on the upper part of the diaphragm.

[0006] The working principle of this utility model is as follows: The connecting rod in this respirator can rotate through a through hole on the support base via a rotating rod, conforming to the lever principle. During use, the inlet pipe is connected to the oxygen source. In the non-operating state, oxygen fills the buffer airway, and the atmospheric pressure inside the top shell balances with the oxygen pressure in the buffer airway, causing the thin valve to tightly seal the buffer air hole, preventing oxygen leakage. When inhaling oxygen, the user inhales through the outlet pipe. At this time, the pressure inside the top shell decreases, and the air pressure in the supplementary airway pushes up the diaphragm, pushing the pressure plate upwards. This causes the push rod at the other end of the connecting rod to move downwards, pushing the thin valve away from the buffer air hole, creating a passage between the buffer air hole and the buffer airway. Oxygen enters the top shell and is finally inhaled into the body through the outlet pipe, achieving oxygen inhalation. When oxygen inhalation stops, the air pressure in the top shell balances again with the buffer and supplementary airways. The diaphragm and pressure plate return to their original positions, and the push rod rises, causing the thin valve to tightly seal the buffer air hole again, preventing oxygen leakage and stopping oxygen supply.

[0007] As a further improvement of this utility model, the bottom of the air supply channel is provided with several air supply holes.

[0008] Air can be introduced through the vents for replenishment, making it easier for users to inhale oxygen.

[0009] As a further improvement of this utility model, the sealing cap is provided with a number of screw holes around its perimeter, and the air supply channel is provided with a number of screws that match the screw holes.

[0010] The stability of the sealed gland is improved by connecting the screw rod to the screw hole. At the same time, the screw rod can be connected by screwing in the screw hole to further improve the connection stability.

[0011] As a further improvement of this utility model, the small sealing cap is provided with connecting ears on both sides, and the connecting ears are provided with connecting holes for connecting with the screws provided around the buffer air holes.

[0012] The small sealing cap is connected to the screw rod via a connecting lug, or a screw can be screwed into the connecting hole to connect the screw rod, further improving the connection stability.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a linkage to open and close the oxygen passage through the lever principle. The opening and closing time can be adapted to the user's breathing movements and frequency. When the user is inhaling oxygen, the oxygen passage is open, and when the user stops inhaling oxygen, the passage is immediately closed, effectively saving oxygen.

[0014] 2. This utility model creates a balanced air pressure on the top and bottom of the membrane by setting up an air supply channel. When oxygen is inhaled, the air pressure at the top of the membrane decreases, and the bottom of the membrane is more likely to shift with the help of atmospheric pressure, which reduces oxygen absorption resistance and improves the service life of the membrane.

[0015] 3. The soft rubber valve plate and diaphragm of this utility model are placed on the buffer air passage and the air supply air passage in a sleeve manner. They can be removed by pressing with the sealing cap. When replacing, you only need to remove the sealing cap, which is convenient and quick. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings. In the embodiments, unless otherwise specified, the technical means used are all conventional technical means in the art. Example

[0020] like Figure 1-2 The micro-resistance breathing regulator shown includes a bottom shell 1, a top shell 2, a sealing cap 3, a connecting rod 4, a soft rubber diaphragm 5, and a soft rubber valve 6; The bottom shell 1 is provided with an air inlet pipe 7 on its side, and a buffer air passage 24 and a replenishing air passage 20 are provided inside the bottom shell 1. The buffer air passage 24 and the replenishing air passage 20 are arranged adjacent to each other. The top of the buffer air passage 24 is provided with a soft rubber valve plate 6, and the top of the replenishing air passage 20 is provided with a limiting groove 21 for placing a soft rubber diaphragm 5. The top shell 2 is sleeved on the top of the bottom shell 1, and the top of the top shell 2 is provided with an air outlet pipe 8 that connects to its interior. The sealing cap 3 is fixed with a support base 12 on its side. There is a pair of support bases 12 arranged in parallel. The top of the support base 12 has a through hole 13 through its main body. The bottom of the support base 12 is fixed with a small sealing cap 11. The middle of the small sealing cap 11 has a buffer air hole 23 through its main body. The sealing cap 3 and the small sealing cap 11 are respectively matched with the top of the air supply channel 20 and the buffer air channel 24. The soft rubber diaphragm 5 has a thin film 9 in the middle, and the thin film 9 is connected to the inner side of the soft rubber diaphragm 5 through the annular inclined surface 26 to form a groove; The soft rubber valve plate 6 has a hollowed-out center and is connected to a thin valve plate 10. The diameter of the soft rubber valve plate 6 matches the top diameter of the buffer air passage 24, and the diameter of the thin valve plate 10 is 3-5mm larger than the diameter of the buffer air hole 23. Both the soft rubber diaphragm 5 and the soft rubber valve plate 6 are made of medical-grade materials; The connecting rod 4 has a rotating hole 17 in the middle for connecting the rotating rod 16. The rotating rod 16 is sleeved in the through hole 13 of the support base 12, so that the connecting rod 4 is located in the middle of the two support bases 12. One end of the connecting rod 4 is connected to the top rod 18, and the other end is connected to the pressure plate 19. The top rod 18 is placed in the buffer air hole 23 and is located above the thin valve plate 10. The diameter of the top rod 18 is 2-3 mm smaller than the diameter of the buffer air hole 23. The pressure plate 19 is placed on the upper part of the film 9.

[0021] The working principle of this embodiment is as follows: In this embodiment, the connecting rod 4 of the respirator can rotate in the through hole 13 on the support base 12 via the rotating rod 16, conforming to the lever principle. During use, the inlet pipe 7 is connected to the oxygen source. In the non-working state, oxygen fills the buffer airway 24, and the atmospheric pressure inside the top shell 2 balances the oxygen pressure in the buffer airway 24, causing the thin valve plate 10 to tightly seal the buffer air hole 23, preventing oxygen leakage. When inhaling oxygen, the user inhales through the outlet pipe 8. At this time, the pressure inside the top shell 2 decreases, and the air pressure in the supplementary airway 20 pushes up the film 9, thereby pushing the pressure plate 19 upward. This causes the top rod 18 at the other end of the connecting rod 4 to move downward, pushing the thin valve plate 10 away from the buffer air hole 23, creating a passage between the buffer air hole 23 and the buffer airway 24. Oxygen enters the top shell 2 and is finally inhaled into the body through the outlet pipe 8, achieving oxygen inhalation. When oxygen supply stops, the air pressure in the top shell 2 is balanced again with the buffer airway 24 and the supplementary airway 20. The membrane 9 and the pressure plate 19 return to their original positions, and the top rod 18 is raised, so that the thin valve plate 10 is tightly pressed against the buffer air hole 23 to prevent oxygen from overflowing, thus achieving the purpose of stopping oxygen supply.

[0025] The working principle of this implementation is the same as that of Example 2. The stability of the sealing cover 3 is improved by connecting the screw 22 to the screw hole 15. At the same time, the screw 22 can be connected by screwing in the screw hole 15 to further improve the connection stability. Example
