Description

Technical field

[0001] The utility model relates to the technical field of gas vibration, in particular to a gas vibration chamber and a device. [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 ciliary 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 cause respiratory infections, thereby triggering infections 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 motion of piston pumps or other mechanical devices to drive gas oscillations. This design uses mechanical mechanisms and electronic circuits to achieve changes in the flow cross-section of the gas during the flow process under the control of electromagnetic valves, ultimately achieving changes in the pressure and speed of the 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 provided on the shell, and a valve assembly provided 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 existing technology 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. [Utility Model Content]

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

[0007] A housing is provided with an air inlet, an air return port, an air outlet, and an air vent, wherein the air inlet, the air outlet, and the air return port are connected, and the air vent is connected to the external atmosphere;

[0008] The housing comprises:

[0009] Middle shell;

[0010] Upper cover;

[0011] A lower cover, wherein the upper cover is arranged above the middle shell, and the lower cover is arranged below the middle shell;

[0012] The air inlet is opened and passes through the lower cover, the air release port and the air outlet are opened in the middle shell, and the air return port is opened and passes through the upper cover.

[0013] It should be noted that the middle shell, the upper cover and the lower cover can be of an integrated design or a split design and then assembled together.

[0014] Specifically, the gas vibration chamber further includes:

[0015] a first cavity, which is opened inside the shell and communicates with the air inlet;

[0016] The second cavity is opened inside the shell, and a connecting hole is provided between the first cavity and the second cavity, so that the first cavity and the second cavity are communicated.

[0017] Specifically, the second cavity is provided with a first side wall, a second side wall and a third side wall;

[0018] The first side wall, the second side wall and the third side wall are distributed in a step shape.

[0019] The second cavity can be divided into:

[0020] 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;

[0021] The deflation zone is connected to the deflation port, and the deflation zone is connected to the external atmosphere through the deflation port;

[0022] The return air zone is connected to the return air port;

[0023] The air intake area, the air release area and the air return area are arranged in sequence.

[0024] The present application also provides a gas vibration device, comprising:

[0025] The gas vibration cavity,

[0026] a sealing member disposed in the second cavity;

[0027] A switch is arranged between the air outlet and the air return port.

[0028] 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.

[0029] Thus, vibrating gas is generated inside the second cavity. In this process, no electromagnetic valve or mechanical switch is required for control. This technical solution has a simple structure, easy operation, high reliability, and is not prone to failure.

[0030] Specifically, the sealing element includes:

[0031] a first sealing member, the first sealing member being disposed between the air inlet area and the air discharge area, the first sealing member being engaged with an inner wall of the housing;

[0032] A second sealing member is provided between the air return area and the air release area, and the second sealing member is engaged with the inner wall of the shell.

[0033] Specifically, the sealing member is made of elastic material.

[0034] Specifically, the second sealing member includes:

[0035] abutment;

[0036] a vibration portion, wherein the abutting portion and the vibration portion are integrally formed;

[0037] an edge portion, wherein the abutting portion, the vibrating portion, and the edge portion extend from the inside to the outside;

[0038] The shape of the vibration portion changes, and the edge portion is engaged and connected with the shell.

[0039] Specifically, the gas vibration device further includes:

[0040] a second abutting member, the second abutting member being disposed between the first sealing member and the second sealing member, and abutting against the first sealing member and the second sealing member;

[0041] A first abutting member is provided between the first sealing member and the connecting hole, one end of the first abutting member abuts the first sealing member, and the other end of the first abutting member abuts the connecting hole.

[0042] Specifically, when the first abutting member abuts against the connecting hole, the air inlet and the air outlet are not connected.

[0043] Specifically, the second abutting member includes a recessed area, and the second sealing member includes a raised area, and the recessed area and the raised area are engaged with each other.

[0044] Specifically, the first abutting member and / or the second abutting member slide relative to the inner wall of the second cavity.

[0045] The working principle of the gas vibration device is:

[0046] 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;

[0047] 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;

[0048] The adjusted gas enters the gas return zone through the gas return port, and the pressure of the gas return zone continues to rise;

[0049] 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;

[0050] 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;

[0051] The air pressure in the air return zone decreases, and the first abutting member no longer abuts against the connecting hole.

[0064] The present invention provides a gas vibration device 01, comprising a housing 03. The shape of the housing 03 is not specifically limited in the present invention, and its external shape can be cylindrical, square or polygonal, all of which are protected by the present invention.

[0065] In the utility model, the shell 03 is a structure designed with an internal storage space 05. The surface of the shell 03 is provided with an air inlet 031, an air return port 032, an air outlet 033 and an air vent 034, wherein the air inlet 031, the air outlet 033 and the air return port 032 are connected, and the air vent 034 is connected to the external atmosphere. The air inlet 031, the air return port 032, the air outlet 033 and the air vent 034 are opened on the outer surface of the shell 03 and then pass through the storage space 05. In the utility model, the positional relationship of the air inlet 031, the air return port 032, the air outlet 033 and the air vent 034 is not limited to a single limit, and the position of the opening can be changed according to actual needs. In the utility model, 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.

[0066] The housing 03 comprises a middle housing 038, an upper cover 039, and a lower cover 037. The upper cover 039 is disposed above the middle housing 038, and the lower cover 037 is disposed below the middle housing 038. The air inlet 031 extends through the lower cover 037, the air vent 034 and the air outlet 033 are disposed in the middle housing 038, and the air return port 032 extends through the upper cover 039.

[0067] It should be noted that the middle housing 038, the upper cover 039, and the lower cover 037 can be of an integrated design or a separate design and then assembled together. The second cavity 053 is provided with a first side wall 0531, a second side wall 0533, and a third side wall 0535; the first side wall 0531, the second side wall 0533, and the third side wall 0535 are arranged in a stepped manner.

[0068] The accommodating space 05 can be divided into a first cavity 051 and a second cavity 053. The first cavity 051 is located inside the housing 03 and communicates with the air inlet 031. Gas first enters the first cavity 051 through the air inlet 031. The second cavity 053 is also located inside the housing 03. A connecting hole 055 is provided between the first cavity 051 and the second cavity 053. The first cavity 051 and the second cavity 053 are connected through the connecting hole 055.

[0069] 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 circular, square, or other shapes, which are not listed here.

[0070] The second cavity 053 can be divided into an air intake area 0531, an air discharge area 0533, and an air return area 0535, which are arranged in sequence. The air intake area 0531 is connected to the first cavity 051 via the connection hole 055. The air intake area 0531 is also connected to the air outlet 033; the air outlet 033 is located 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 connection hole 055, and then flows out through the air outlet 033. The air outlet 033 and the air return area 032 are connected by a pipe 07. Similarly, the gas flows through the pipe 07 to the air return area 032 and then enters the air return area 0535.

[0071] It should be noted that a switch 09 is provided on the pipe 07. The switch 09 is used to adjust the speed. That is, the pressure of the gas flowing from the outlet 033 through the switch 09 changes before and after the gas flows through the switch 09. Specifically, the pressure of the gas increases after passing through the switch 09. Ultimately, the pressure of the gas flowing through the inlet 031 and the outlet 033 is lower than the pressure of the gas flowing through the return port 032.

[0072] The air release area 0533 is connected to 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 connected to the air return port 032 .

[0073] 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.

[0074] 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 intervals, 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.

[0075] 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 discharge area 0533 , and at the same time isolating the air discharge area 0533 from the air return area 0535 .

[0076] The first sealing member 021 and the second sealing member 022 are made of an elastic material, such as silicone, rubber, or other elastic material. Under the pressure of the gas, the first sealing member 021 and the second sealing member 022 can deform. During this deformation process, the edges of the first sealing member 021 and the second sealing member 022 always engage with the interior of the housing 03.

[0077] 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 engaged and connected with the shell 03.

[0078] 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.

[0079] 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 helps to generate vibrating gas, and its edge portion 0225 is always engaged with the inner wall of the inner shell.

[0080] 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 .

[0081] 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 .

[0082] The main body of the second abutting member 041 is concave, while the first sealing member 021 is convex. The main body of the second abutting member 041 and the first sealing member 021 abut each other. 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 the first sealing member 021, and the other end abuts the connecting hole 055.

[0083] It should be noted that the main portion of the second abutting member 041 is designed to be concave, and the first sealing member 021 is designed to be convex, so that the fit between the two is more stable and tight, which is conducive to the transmission of force.

[0084] The first abutment member 042 is T-shaped, 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 .

[0085] It should be noted that when the bottom surface of the first abutting member 042 abuts against the connecting hole 055, 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 being unable to communicate, and gas cannot flow.

[0086] 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 .

[0087] 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 the connecting hole 055. At this time, the air inlet 031 and the air outlet 033 are blocked.

[0088] 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, and thus cannot cause the bottom surface of the first abutment member 042 to abut against the connecting hole 055.

[0089] Furthermore, the bottom surface of the first abutting member 042 no longer abuts the connecting hole 055, 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 return air zone 032. The pressure of the gas in the return air zone 032 continues to increase, further pushing the second abutting member 041 and the first abutting member 042 to move as a whole, thus preventing the bottom surface of the first abutting member 042 from abutting the connecting hole 055.

[0090] As a result, the second abutting member 041 and the first abutting member 042 reciprocate inside the second cavity 053 to generate vibrating gas.

[0091] It should be noted that since the degassing area 0533 is connected to the degassing port 034, the degassing area 0533 is connected to the external atmosphere through the degassing port 034. Since the second abutting member 041 is located in the degassing area, the gas pressure around the second abutting member 041 is atmospheric pressure, and the gas pressure of the surrounding environment does not change. During the process of generating vibrating gas, the second abutting member 041 serves as a transmission element and is not affected by pressure changes. The transmission stability of the second abutting member 041 is good and is not subject to interference.

[0092] The utility model also provides a gas vibration method, which is applied to the gas vibration device, comprising:

[0093] S1. Injecting gas into the first cavity through the gas inlet, and then pushing the first abutment member so that the gas inlet and the gas outlet are connected;

[0094] S2. 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;

[0095] 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;

[0096] S4, 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;

[0097] 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;

[0098] S6. The air pressure in the air return zone decreases, and the first abutting member no longer abuts against the connecting hole.

[0099] The present invention further 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 .

[0100] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
