Description

[Technical field]

[0001] The present invention relates to the field of gas vibration technology, and in particular to a gas vibration device, method and equipment. [Background technology]

[0002] Complications caused by respiratory diseases or other diseases are likely to cause damage to the function of airway cilia, and sputum may become viscous and difficult to cough up. At the same time, damaged cilia function will also interfere with the cough reflex. In addition, the accumulation and retention of respiratory secretions provide opportunities for bacteria to colonize the airways and respiratory infections, thereby inducing infection and inflammatory reactions, leading to damage to airway and lung tissue. Therefore, clearing airway secretions as soon as possible is very important to reduce the incidence of complications such as pneumonia. Most existing technologies achieve sputum removal and improve respiratory function by continuously providing high-frequency oscillating gas.

[0003] Existing gas vibration devices generally use the reciprocating movement of piston pumps or other mechanical devices to drive gas oscillation. This design uses mechanical mechanisms and electronic circuits to achieve changes in the flow cross-section of gas during the flow process under the control of electromagnetic valves, and ultimately achieve changes in the pressure and speed of gas flow, thereby generating oscillating gas. For example:

[0004] The patent number is CN117869342A, and the patent name is high-frequency oscillation mechanism and expectorant, which includes a shell, a driving mechanism arranged on the shell, and a valve assembly arranged on the shell; wherein the shell has an air inlet and an air outlet; the driving mechanism is used to adjust the opening of the valve assembly; the valve assembly is used to control the ventilation volume of the air inlet and the air outlet; the air inlet is connected to the air outlet pipe of the blower, and the air outlet is connected to the air inlet pipe of the blower.

[0005] However, actual use and market research have shown that the overall design of the prior art is complex, and there is a risk of failure of electronic components (especially switches), which will cause the gas switch to fail to operate or to operate incorrectly. [Summary of the invention]

[0006] In view of the above technical problems in the prior art, the present invention provides a gas vibration device, comprising:

[0008] A first cavity is opened inside the shell, and the first cavity is connected to the air inlet;

[0009] The second cavity is opened inside the shell, a connecting hole is provided between the first cavity and the second cavity, the first cavity and the second cavity are connected; the second cavity can be divided into:

[0010] An air inlet area; the air inlet area is connected to the first cavity through the connecting hole, and the air inlet area is connected to the air outlet;

[0011] The air release zone is connected to the air release port, and the air release zone is connected to the external atmosphere through the air release port;

[0014] a sealing member, the sealing member being disposed in the second cavity;

[0015] A switch is arranged between the air outlet and the air return port.

[0016] The beneficial effect is that the pressure difference between the gases, specifically the pressure difference between the return air zone and the air inlet zone, causes intermittent connection and closing between the air inlet and the air outlet, thereby causing the pressure difference to exist when the air inlet and the air outlet are connected, and the pressure difference disappears when the air inlet and the air outlet are closed.

[0017] Thus, vibrating gas is generated inside the second cavity. In this process, it is not necessary to use electromagnetic valves or mechanical switches for control. The technical solution has a simple structure, convenient operation, high reliability, and is not prone to failure.

[0018] Specifically, the sealing element includes:

[0030] Specifically, when the first abutting member abuts against the connecting hole, the air inlet and the air outlet are not connected.

[0031] Specifically, the second abutment member includes a recessed area, the second sealing member includes a raised area, and the recessed area and the raised area are engaged with each other.

[0032] Specifically, the first abutting member and / or the second abutting member slides relative to the inner wall of the second cavity.

[0033] The present invention also provides a gas vibration method, which is applied to the gas vibration device, comprising:

[0034] Injecting gas into the first cavity through the gas inlet, and then the gas pushes the first abutment member to connect the gas inlet and the gas outlet;

[0035] The gas passes through the switch, and the switch adjusts the flow rate of the gas, and the adjusted gas flows into the gas return port;

[0036] The adjusted gas enters the gas return zone through the gas return port, and the pressure of the gas return zone continues to rise;

[0037] The adjusted gas presses the second sealing member, the second abutting member, the first sealing member, and the first abutting member to slide relative to the inner wall of the housing, so that the first abutting member abuts against the connecting hole;

[0038] When the first abutment member abuts against the connection hole, the air inlet and the air outlet are no longer connected, so that the gas cannot flow into the air return port through the air outlet;

[0039] The air pressure in the air return zone decreases, and the first abutment member no longer abuts against the connection hole.

[0040] The present invention also provides a gas vibration device, comprising:

[0041] The gas vibration device; a terminal device, which is electrically connected to the gas vibration device.

[0054] The present invention provides a gas vibration device 01, comprising a shell 03. The shape of the shell 03 is not specifically limited in the present invention, and its external shape can be cylindrical, cubic or polygonal, all of which are protected by the present invention.

[0055] In the invention, the shell 03 is a structure designed with a storage space 05 inside. An air inlet 031, an air return port 032, an air outlet 033 and an air leak 034 are provided on the surface of the shell 03, wherein the air inlet 031, the air outlet 033 and the air return port 032 are connected, and the air leak 034 is connected to the external atmosphere. The air inlet 031, the air return port 032, the air outlet 033 and the air leak 034 are provided on the outer surface of the shell 03, and then pass through the storage space 05. In the present invention, the positional relationship between the air inlet 031, the air return port 032, the air outlet 033 and the air leak 034 is not limited solely, and the positions of the air inlet 031, the air return port 032 and the air outlet 033 can be changed according to actual needs. In the present invention, the air inlet 031, the air return port 032 and the air outlet 033 are connected to each other or cut off from each other to generate a vibrating airflow. The air vent 034 is connected to the atmosphere.

[0056] The accommodating space 05 can be divided into a first cavity 051 and a second cavity 053, wherein the first cavity 051 is opened inside the shell 03, and the first cavity 051 is communicated with the air inlet 031, and the gas first enters the first cavity 051 through the air inlet 031. The second cavity 053 is also opened inside the shell 03, and a connecting hole 055 is provided between the first cavity 051 and the second cavity 053, and the first cavity 051 and the second cavity 053 are communicated through the connecting hole 055.

[0057] Similarly, the gas also enters the second cavity 053 through the connecting hole 055. It should be noted that the cross-sectional area of ​​the connecting hole 055 is smaller than the cross-sectional areas of the first cavity 051 and the second cavity 053. In the present invention, the shape of the connecting hole 055 can be a circular hole, or a square hole or other shapes, which are not listed here.

[0058] The second cavity 053 can be divided into an air intake area 0531, an air discharge area 0533 and an air return area 0535, and the air intake area 0531, the air discharge area 0533 and the air return area 0535 are arranged in sequence. The air intake area 0531 is connected to the first cavity 051 through the connecting hole 055, and the air intake area 0531 is connected to the air outlet 033; wherein the air outlet 033 is arranged on the side of the air intake area 0531. When the gas passes through the air intake 031, it first enters the first cavity 051, then enters the air intake area 0531 through the connecting hole 055, and then flows out through the air outlet 033. The air outlet 033 and the air return port 032 are connected by a pipe 07. Similarly, the gas passes through the pipe 07, flows to the air return port 032, and then enters the air return area 0535.

[0059] It should be noted that a switch 09 is provided on the pipeline 07, and the switch 09 is used for speed regulation, that is, the pressure of the gas changes before and after the gas flows through the switch 09 from the gas outlet 033, and specifically, the pressure of the gas increases after passing through the switch 09. Finally, the pressure of the gas flowing through the gas inlet 031 and the gas outlet 033 is lower than the pressure of the gas flowing through the gas return port 032.

[0060] The air release area 0533 is in communication with the air release port 034 , and the air release area 0533 is connected to the external atmosphere through the air release port 034 ; the air return area 0535 is in communication with the air return port 032 .

[0061] It should be noted that the air discharge area 0533 and the air intake area 0531 are not connected, and the air discharge area 0533 and the air return area 0535 are not connected.

[0062] A seal 02 is provided in the second cavity 053, and the seal includes a first seal 021 and a second seal 022. The first seal 021 and the second seal 022 are arranged at an interval, and the first seal 021 and the second seal divide the second cavity 053 into the air intake area 0531, the air discharge area 0533 and the air return area 0535, wherein the first seal 021 is arranged between the air intake area 0531 and the air discharge area 0533, and the first seal 021 is engaged with the inner wall of the shell 01; the second seal 022 is arranged between the air return area 0535 and the air discharge area 0533, and the second seal 022 is engaged with the inner wall of the shell 03.

[0063] It should be noted that the first sealing member 021 and the second sealing member play a sealing role, isolating the air intake area 0531 from the air leakage area 0533 , and at the same time isolating the air leakage area 0533 from the air return area 0535 .

[0064] The first seal 021 and the second seal 022 are made of elastic materials, such as silicone, rubber and other elastic materials. The first seal 021 and the second seal 022 can be deformed under the pressure of the gas. During the deformation process, the edges of the first seal 021 and the second seal 022 are always engaged with the inside of the housing 03.

[0065] Taking the second sealing member 022 as an example, it includes a contact portion 0221; a vibration portion 0223, wherein the contact portion 0221 and the vibration portion 0223 are integrally formed; and an edge portion 0225, wherein the contact portion 0221, the vibration portion 0223 and the edge portion 0225 extend from the inside to the outside; wherein the shape of the vibration portion 0223 changes, and the edge portion 0225 is snap-connected with the shell 03.

[0066] It should be noted that, in a preferred embodiment of the present invention, the second sealing member 022 is in the form of a film.

[0067] It should be noted that the abutting portion 0221 abuts against the second abutting member 041, and the vibrating portion 0223 is in the form of a thin film, which can be deformed and move back and forth under the action of pressure difference, which is helpful to generate vibrating gas, and its edge portion 0225 is always engaged with the inner wall of the inner shell.

[0068] The gas vibration device 01 further includes an abutment member 04 , and the abutment member 04 includes a second abutment member 041 and a first abutment member 042 .

[0069] The second abutting member 041 is disposed between the first sealing member 021 and the second sealing member 022 , and the second abutting member 041 abuts against the first sealing member 021 and the second sealing member 022 .

[0070] The main body of the second abutting member 041 is concave, and the first sealing member 021 is convex. The main body of the second abutting member 041 abuts against the first sealing member 021. The first abutting member 042 is disposed between the first sealing member 021 and the connecting hole 055, one end of the first abutting member 042 abuts against the first sealing member 021, and the other end of the first abutting member 042 abuts against the connecting hole 055.

[0071] It should be noted that the main part of the second abutment member 041 is designed to be concave, and the first sealing member 021 is convex, so that the fit between the two is more stable and tight, which is conducive to the transmission of force.

[0072] The first abutment member 042 is in a "T" shape, the side wall of the air inlet area 0531 is designed to be stepped, the side surface of the first abutment member 042 cooperates with the stepped shape, and the bottom surface of the first abutment member 042 abuts against the first sealing member 021.

[0073] It should be noted that when the bottom surface of the first abutting member 042 abuts against the connecting hole 055, the abutting here means that the bottom surface of the first abutting member 042 completely blocks the connecting hole 055, resulting in the air inlet 031 and the air outlet 033 being cut off, the two cannot be connected, and the gas cannot flow.

[0074] It should be noted that the pressure of the gas flowing through the air inlet 031 and the air outlet 033 is lower than the pressure of the gas flowing through the air return port 032 .

[0075] At this time, since the first sealing member 021 and the second sealing member 022 are elastic members, the pressure difference of the gas causes the second abutting member 041 and the first abutting member 042 to move as a whole until the bottom surface of the first abutting member 042 abuts against the connecting hole 055. At this time, the air inlet 031 and the air outlet 033 are blocked.

[0076] The air outlet 033 cannot continue to supply air to the air return port 032, thereby causing the gas pressure in the air return area 0535 to decrease, and thus cannot continue to push the second abutment member 041 and the first abutment member 042 to move as a whole, thereby causing the bottom surface of the first abutment member 042 to abut against the connecting hole 055.

[0077] Furthermore, the bottom surface of the first abutting member 042 and the connecting hole 055 are no longer in contact, and the air inlet 031 is connected to the air outlet 033. After passing through the switch 08, the gas continues to flow to the air return area 032, and the pressure of the gas in the air return area 032 continues to increase, which once again pushes the second abutting member 041 and the first abutting member 042 to move as a whole, thereby preventing the bottom surface of the first abutting member 042 from contacting the connecting hole 055.

[0078] As a result, the second abutment member 041 and the first abutment member 042 reciprocate inside the second cavity 053 to generate vibrating gas.

[0079] It should be noted that, since the air release area 0533 is connected to the air release port 034, the air release area 0533 is connected to the external atmosphere through the air release port 034, and the second abutment member 041 is arranged in the air release area, the gas pressure around the second abutment member 041 is the atmospheric pressure, and the gas pressure of the environment in which it is located does not change. In the process of generating vibrating gas, the second abutment member 041 is used as a transmission member and is not affected by pressure changes. The second abutment member 041 has good transmission stability and is not subject to interference.

[0080] The present invention also provides a gas vibration method, which is applied to the gas vibration device, comprising:

[0081] S1, injecting gas into the first cavity through the gas inlet, and then the gas pushes the first abutment member to make the gas inlet and the gas outlet communicate with each other;

[0082] S2, the gas passes through the switch, the switch adjusts the flow rate of the gas, and the adjusted gas flows into the gas return port;

[0083] S3, the adjusted gas enters the gas return zone through the gas return port, and the pressure of the gas return zone continues to rise;

[0084] S4, the adjusted gas squeezes the second sealing member, the second abutting member, the first sealing member, and the first abutting member to slide relative to the inner wall of the housing, so that the first abutting member abuts against the connecting hole;

[0085] S5. When the first abutting member abuts against the connecting hole, the air inlet and the air outlet are no longer connected, so that the gas cannot flow into the air return port through the air outlet;

[0086] S6. The air pressure in the air return zone decreases, and the first abutting member no longer abuts against the connecting hole.

[0087] The present invention also provides a gas vibration device 00, comprising: the gas vibration device 01; and a terminal device 06, which is electrically connected to the gas vibration device 01.

[0088] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
