[0059] The following describes the specific implementation of the embodiment of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiment of the present invention and is not intended to limit the embodiment of the present invention.

[0060] In the embodiments of the present invention, unless otherwise specified, directional words such as "up, down, left, right" generally refer to the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use.

[0061] The terms "first", "second", "third", etc. are only used for distinction and description and should not be understood as indicating or implying relative importance.

[0062] The terms "parallel" and "perpendicular" do not necessarily mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that the direction is more parallel than "perpendicular", not that the structure must be completely parallel, but rather that it can be slightly tilted.

[0063] Terms such as "horizontal," "vertical," and "overhanging" do not necessarily mean that a component must be absolutely horizontal, vertical, or overhanging. A slight tilt is permitted. For example, "horizontal" simply means that its direction is more horizontal than "vertical." It does not mean that the structure must be completely horizontal, but rather that a slight tilt is permitted.

[0064] Furthermore, terms like "approximately" and "substantially" are intended to clarify that the relevant content does not require absolute precision, but rather allows for certain deviations. For example, "approximately equal" does not simply mean absolute equality. Because absolute equality is difficult to achieve in actual production and operational processes, certain deviations generally exist. Therefore, in addition to absolute equality, "approximately equal" also encompasses the aforementioned situation of certain deviations. Taking this as an example, in other contexts, unless otherwise specified, terms like "approximately" and "substantially" have similar meanings as described above.

[0065] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0067] like Figure 1-2 As shown, this embodiment provides a breathing-based air supply valve, which can realize the supply of oxygen, other types of gases, or a mixture of oxygen and other types of gases. The breathing-based air supply valve 1 includes:

[0068] A valve body 11 is provided with a plurality of accommodating spaces, an air supply pipe 12 and a breathing sensing pipe 13 are provided on the valve body 11, and an air control channel and an air supply channel are opened in the valve body 11, and both the air control channel and the air supply channel are connected to the air inlet of the breathing-based air supply valve 1;

[0069] The breathing sensing component 14 is disposed in the corresponding accommodation space within the valve body 11 and is configured to displace to open the air control channel when the breathing sensing tube 13 senses the user inhaling, and to reset to close the air control channel when the breathing sensing tube 13 senses the user stopping inhaling;

[0070] The air supply on-off component 15 is arranged in the corresponding accommodating space in the valve body 11. The air supply on-off component 15 is used to generate displacement to open the air supply channel after the air control channel is opened, and start supplying air through the air supply pipe 12, and reset to close the air supply channel after the air control channel is closed, and stop supplying air through the air supply pipe 12.

[0071] Specifically, in this embodiment, an air supply pipe 12 and a breathing sensing pipe 13 are provided on the valve body 11. The fixed ends of the air supply pipe 12 and the breathing sensing pipe 13 are located inside the valve body 11, and the connecting ends of the air supply pipe 12 and the breathing sensing pipe 13 pass through the valve body 11 and are located outside the valve body 11. In order to realize the function of only supplying air when the person is inhaling and not supplying air when the person is not inhaling, the valve body 11 is configured to have multiple accommodating spaces, and an air control channel and an air supply channel are opened in the valve body 11;

[0072] In order to achieve control of the air control channel, a breathing sensing component 14 is provided. The breathing sensing component 14 is disposed in the corresponding accommodation space and is configured to generate displacement to open the air control channel when the breathing sensing tube 13 senses the user inhaling, and reset to close the air control channel when the breathing sensing tube 13 senses the user stopping inhaling.

[0073] In order to achieve control of the air supply channel, the air supply on-off component 15 is arranged in the corresponding accommodation space, located below the breathing sensing component 14, and is used to generate displacement to open the air supply channel after the air control channel is opened, and start supplying air through the air supply pipe 12, and reset to close the air supply channel after the air control channel is closed, and stop supplying air through the air supply pipe 12.

[0074] More specifically, the breathing-based air supply valve in this embodiment is suitable for scenarios with low gas source pressure, such as centralized gas supply pipelines in wards, oxygen concentrators used by patients at home, oxygen bags, low-pressure oxygen cylinders, etc., and can specifically be used in scenarios where the pressure value is less than 150 kPa.

[0075] Furthermore, if Figure 1-2 The valve body 11 shown includes:

[0076] The valve cover 111, the first valve body 112 and the second valve body 113 are arranged in sequence from top to bottom;

[0077] The first valve body 112 is provided with a first channel 101, a second channel 102 and a third channel 103;

[0078] The second valve body 113 is provided with a fourth channel 104 and a fifth channel 105 , and the bottom end of the second valve body 113 is provided with an air inlet channel 106 , which serves as an air inlet of the breathing-based air supply valve 1 ;

[0079] The first channel 101, the second channel 102, the third channel 103 and the fourth channel 104 together constitute the air control channel;

[0080] The fifth channel 105 serves as the air supply channel.

[0081] Specifically, in this embodiment, the valve body 11 is sequentially arranged from top to bottom with a valve cover 211, a first valve body 112, and a second valve body 113. This arrangement significantly reduces manufacturing and assembly costs, thereby significantly reducing the cost of using the breath-based air supply valve 1. The air control channel and the air supply channel are independently controlled, ensuring control accuracy.

[0082] Furthermore, if Figure 1-2 The breathing sensing component 14 shown includes:

[0083] The sensing diaphragm 141 is arranged in the accommodating space between the valve cover 111 and the first valve body 112, and covers the first channel 101; when the user inhales, negative pressure is formed on the upper surface of the sensing diaphragm 141, causing the sensing diaphragm 141 to move upward, thereby opening the air control channel; when the user stops inhaling, the negative pressure on the upper surface of the sensing diaphragm 141 disappears, causing the sensing diaphragm 141 to reset and close the air control channel.

[0084] Specifically, in this embodiment, the sensing diaphragm 141 is arranged in the accommodating space between the valve cover 111 and the first valve body 112, and when no air is supplied, and during use, but the inhaling person is in a stopped inhalation state, the sensing diaphragm 141 blocks the first channel 101. When the user inhales, the gas in the breathing sensing tube 13 moves outward. At this time, gas movement will occur on the upper surface of the sensing diaphragm 141, forming a negative pressure, and an upward force, causing the sensing diaphragm 141 to move upward, opening the first channel 101, and thus making the air control channel conductive; when the user stops inhaling, the gas in the breathing sensing tube 13 moves inward, the negative pressure disappears, and the upward force disappears synchronously, and the sensing diaphragm 141 moves downward and resets, closing the first channel 101, so that the air control channel is closed.

[0085] In another embodiment, a first spring 142 is provided between the valve cover 111 and the sensing diaphragm 141 to assist the sensing diaphragm 141 in quickly resetting when the user stops inhaling. When no air is supplied, or during use, but the person inhaling stops inhaling, the first spring 142 is in a slightly compressed state. At this time, the first spring 142 generates a small force. However, when the user inhales, gas movement occurs on the upper surface of the sensing diaphragm 141, forming a negative pressure. The negative pressure is sufficient to cause the sensing diaphragm 141 to move upward and compress the first spring 142, putting it in a compressed state. When the user stops inhaling, the negative pressure on the upper surface of the sensing diaphragm 141 disappears, and the negative pressure also disappears. At this time, the first spring 142 generates an elastic force to reset the sensing diaphragm 141, quickly closing the air control channel.

[0086] Furthermore, if Figure 1-2 As shown, the breathing sensing tube 13 is arranged on the valve cover 111 , the tube mouth is communicated with the accommodating space between the valve cover 111 and the first valve body 112 , and is located above the sensing diaphragm 141 .

[0087] Specifically, in this embodiment, the breathing sensing tube 13 is disposed on the valve cover 111 and above the sensing diaphragm 141 in this manner, thereby ensuring the effect of negative pressure generation above the sensing diaphragm 141 .

[0088] Furthermore, if Figure 1-2 As shown, a flow limiting member 107 is provided in the fifth channel 105 .

[0089] Specifically, in this embodiment, the flow restrictor 107 provided in the fifth channel 105 is an annular structure with a small hole in its center for gas to pass through. When the gas volume and pressure of the gas source are low, the flow restrictor 107 can limit the maximum flow rate of the gas, thereby ensuring more stable gas output.

[0090] Furthermore, if Figure 1-2 The air supply on-off assembly 15 shown includes:

[0091] The air supply diaphragm 151 is arranged in the accommodating space between the first valve body 112 and the second valve body 113, and covers the fifth channel 105; when the air control channel is opened, the air pressure on the upper surface of the air supply diaphragm 151 decreases, causing the air supply diaphragm 151 to move upward, thereby opening the air supply channel; when the air control channel is closed, the air pressure on the upper surface of the air supply diaphragm 151 increases, and the air supply diaphragm 151 resets under the action of pressure to close the air supply channel.

[0092] Specifically, in this embodiment, when air is not supplied and during use, but the inhaling person is in a stopped inhalation state, the sensing diaphragm 141 blocks the first channel 101, and since the air control channel and the air supply channel are both connected to the air inlet of the breath-based air supply valve, at this time the air pressure value on the upper surface of the air supply diaphragm 151 is greater than the air pressure value on the lower surface (air pressure value), so the air supply diaphragm 151 blocks the fifth channel 105 under the action of pressure, so that the air supply channel is in a closed state; when the pressure is too high, the air supply diaphragm 151 automatically ruptures, thereby achieving safe pressure release and avoiding accidents.

[0093] When the user inhales, the gas in the respiratory sensing tube 13 moves outward. At this time, gas movement will occur on the upper surface of the sensing diaphragm 141, forming a negative pressure, which will generate an upward force, causing the sensing diaphragm 141 to move upward, opening the first channel 101, and thus making the air control channel conductive. At this time, the gas in the air control channel flows outward, making the air pressure on the upper surface of the air supply diaphragm 151 less than the air pressure on the lower surface, and the air supply diaphragm 151 produces an upward displacement, opening the fifth channel 105, so that the air supply channel is in a conductive state, and air can be supplied through the air supply pipe 12.

[0094] When the air supply diaphragm 151 covers the fifth channel 105 , the internal accommodation space where the air supply diaphragm 151 is located is divided into a sealed upper cavity and a lower cavity by the air supply diaphragm 151 , and the air supply diaphragm 151 is connected to the first channel 101 and the second channel 202 .

[0095] In another embodiment, a second spring 152 is provided between the air supply diaphragm 151 and the second valve body 113. When the user stops inhaling, the auxiliary air supply diaphragm 151 moves upward rapidly to open the air supply channel. When no air is supplied, or during use, but the inhaler is in a state of stopping inhalation, the second spring 152 is in a compressed state, generating an elastic force. However, since the air pressure value on the upper surface of the air supply diaphragm 151 is greater than the air pressure value on the lower surface, the elastic force generated by the second spring 152 is insufficient to offset the downward air pressure, and the sensing diaphragm 141 does not produce an upward displacement. When the user starts to inhale, the gas in the air control channel flows outward, causing the air pressure on the upper surface of the air supply diaphragm 151 to be lower than the air pressure on the lower surface. At this time, the first spring 142 generates an elastic force that enables the sensing diaphragm 141 to move upward rapidly, thereby quickly opening the air supply channel.

[0096] In addition, since the air supply diaphragm 151 is an elastic diaphragm with sealing properties, excessive deformation will cause its own destruction. Therefore, the second spring 152 is also used to balance the excess deformation generated by the air supply diaphragm 151 when the air supply diaphragm 151 is under different pressures, so that the deformation of the air supply diaphragm 151 is within the set range, thereby protecting the air supply diaphragm 151 and improving its service life.

[0097] Furthermore, if Figure 1-2 As shown, the air supply pipe 12 is arranged on the second valve body 113 , the pipe mouth is communicated with the accommodation space between the first valve body 112 and the second valve body 113 , and is located below the air supply diaphragm 151 .

[0098] Specifically, in this embodiment, the air supply pipe 12 is disposed on the second valve body 113 and below the air supply diaphragm 151 , which can ensure stable air supply from the air supply pipe 12 after the air supply channel is opened.

[0099] like Figure 3-4 As shown, this embodiment provides an air supply device, which includes:

[0100] The above-mentioned breath-based air supply valve 1;

[0101] The gas storage mechanism 2 is used to store gas, and the gas outlet of the gas storage mechanism 2 is connected to the gas inlet of the breathing-based gas supply valve 1 .

[0102] Specifically, in this embodiment, the gas storage mechanism 2 can be a low-pressure gas source such as a centralized gas supply pipeline in the ward, an oxygen concentrator used by the patient at home, or a gas bag. Furthermore, the gas storage mechanism 2 is connected to the breath-based gas supply valve 1 via a second gas pipeline 5 or a rotary switch 6 to ensure ease of use. Furthermore, the length of the second gas pipeline 5 can be set to a shorter or longer length based on actual usage requirements to facilitate gas delivery.

[0103] Furthermore, if Figure 3 The air supply device further comprises:

[0104] An inhalation mask 3, wherein two through holes 31 are provided on the inhalation mask 3, the inhalation mask 3 has a concave receiving space, and the inhalation mask 3 is detachably provided on the breath-based air supply valve 1;

[0105] The inhalation mask 3 is arranged on the breath-based air supply valve so that the breath-based air supply valve is placed in the accommodation space of the inhalation mask 3;

[0106] When the inhalation mask 3 is removed from the breath-based air supply valve, the air supply pipe 12 and the breathing sensing tube 13 can be inserted into the corresponding through holes 31 on the inhalation mask 3, and the ends of the air supply pipe 12 and the breathing sensing tube 13 are located in the accommodating space of the inhalation mask 3 to perform the air supply operation.

[0107] Specifically, the inhalation mask 3 can have an arc-shaped structure that can match the facial features of most people. In addition, to ensure comfort during inhalation, the inhalation mask 3 is made of rubber or plastic. Furthermore, for ease of installation, two through-holes 31 are provided on the convex surface of the inhalation mask 3. When the air supply device is not used for air supply, the inhalation mask 3 is placed on the breath-based air supply valve 1. The inhalation mask 3 is inserted into the breath-based air supply valve 1 so that the breath-based air supply valve 1 is located in the accommodation space of the inhalation mask 3, thereby protecting the breath-based air supply valve 1 and preventing dust. When the air supply device is used for air supply, the air supply pipe 12 and the breathing sensing pipe 13 are inserted into the corresponding through-holes 31, with the ends of the air supply pipe 12 and the breathing sensing pipe 13 located in the accommodation space of the inhalation mask 3. The inhalation mask 3 is then placed over the face to allow inhalation.

[0108] Furthermore, if Figure 4 The air supply device further comprises:

[0109] The inhalation tube 4 is connected to the air supply tube 12 and the breathing sensing tube 13 of the breathing-based air supply valve 1 to deliver the gas to the user; Figure 5 As shown, the air intake pipe 4 includes:

[0110] A nasal suction head 41 having an internal accommodation space, two air inlets 42 and at least one nasal suction tube 43 are disposed on the nasal suction head 41;

[0111] Two first gas pipelines 44 , the fixed ends of the two first gas pipelines 44 are connected to the corresponding gas inlets 42 , and the connecting ends of the first gas pipelines 44 are provided with joints 45 ;

[0112] Two flow channel accelerators 46 are respectively provided at the air inlet of the nasal nozzle 41, and are used to generate a prompt sound when the air passes through;

[0113] When using the air supply device to supply air, the two joints 45 of the air inhalation tube 4 are respectively connected to the air supply tube 12 and the breathing sensing tube 13 , and the user inhales through the nasal suction tube 43 .

[0114] Specifically, for some situations where it is inconvenient to inhale using the inhalation mask 3, inhalation can be performed through the inhalation tube 4 to increase the convenience of use. When inhaling using the inhalation tube 4, the inhalation tube 4 is connected to the air supply tube 12 and the respiratory sensing tube 13, and inhalation can be performed through the nasal suction tube 43.

[0115] In order to achieve a better air supply effect, at least one nasal suction tube 43 is provided on the nasal suction head 41. When in use, the nasal suction tube 43 is inserted into the nostril; preferably, two nasal suction tubes 43 are provided so that one nasal suction tube 43 can be used for each nostril.

[0116] Specifically, the flow channel accelerator 46 is an annular flow restriction portion arranged in the two air inlets 42. An air hole is provided through the middle of the annular flow restriction portion. When air is supplied through the intake pipe 4, the gas flows through the annular flow restriction portion. Since the diameter of the air hole is smaller than the diameter of the gas pipeline, the airway becomes narrower and a sound is emitted.

[0117] In another embodiment, the air intake pipe further comprises:

[0118] A limiting member is provided with two limiting holes, and the connecting end of the first gas pipeline passes through the corresponding limiting holes to connect to the joint.

[0119] Specifically, since the pipeline has a certain length, it may be entangled during use, which will affect the use effect. Therefore, a limiter is set on the first gas pipeline 44, and two limit holes are set on the limiter. The connecting end of the first gas pipeline 44 passes through the corresponding limit hole and is connected to the joint, so that the limiter can move on the first gas pipeline 44 to adjust the limit position, thereby realizing the position limitation of the two first gas pipelines 44 and avoiding bending and entanglement.

[0120] The above describes in detail the optional implementation methods of the embodiment of the present invention in conjunction with the accompanying drawings.
