Description

Technical Field

[0001] The utility model relates to the field of cough machine accessories, in particular to a percussion structure for a cough machine. Background Art

[0002] The main function of a cough machine is to help patients with insufficient lung motility (or those undergoing oral surgery) expel sputum that has been produced but not removed in time. This is usually done by generating a strong airflow when the patient exhales to remove the sputum. However, due to the strong viscosity of sputum, strong instantaneous airflow is required to remove it. However, the fans used in cough machines are generally small, and the instantaneous airflow pressure may not be sufficient to effectively remove the sputum. Therefore, a percussion structure can be added to the air path to increase the instantaneous airflow pressure. Utility Model Content

[0003] The utility model aims to provide a percussion structure for a coughing machine, so as to solve the problem that the air source pressure of the existing sputum suction machine is insufficient and the sputum suction effect cannot be guaranteed.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a percussion structure for a coughing machine, comprising an output end cover, a cavity is arranged in the output end cover, an air inlet and an air outlet are arranged on the output end cover, a vibrating diaphragm is arranged at one end of the output end cover, the vibrating diaphragm and the cavity are combined to form a variable chamber, the vibrating diaphragm is retractably arranged in the cavity, one end of the vibrating diaphragm is connected to a telescopic driving mechanism, and the vibrating diaphragm is driven to move by the telescopic driving mechanism to change the volume of the variable chamber.

[0005] As a further improvement of the above technical solution:

[0006] Preferably, the telescopic drive mechanism includes a mounting plate and a transmission rod that slides with the mounting plate, the mounting plate is connected to the output end cover, the edge of the vibration diaphragm is connected to the mounting plate, one end of the transmission rod is connected to the center of the vibration diaphragm, and the other end of the transmission rod is connected to a protruding structure.

[0007] Preferably, balancing air holes are provided on the mounting plate.

[0008] Preferably, the extending structure includes a transmission end cover, which is connected to the mounting plate. A motion cavity is provided in the transmission end cover, a permanent magnet is provided in the motion cavity, an electromagnetic cover is slidingly provided outside the permanent magnet, and the electromagnetic cover is connected to the transmission rod.

[0009] Preferably, the vibrating diaphragm is made of a multi-layer composite material, including at least one elastic material layer and at least one reinforcing fiber layer, with the elastic material layer being silicone. This structure not only ensures the elasticity of the vibrating diaphragm, but also enhances its durability and tensile strength, allowing it to maintain good sealing performance even under high-frequency vibrations, thereby increasing instantaneous airflow pressure.

[0010] Preferably, the vibrating diaphragm is provided with reinforcing ribs, which are evenly distributed on the vibrating diaphragm. The reinforcing ribs are used to enhance the stability of the vibrating diaphragm during the expansion and contraction process, thereby ensuring that the airflow generated when tapping is more concentrated and effectively increasing the instantaneous airflow pressure.

[0011] Preferably, the telescopic drive mechanism further comprises a spring, one end of which is fixed to the mounting plate and the other end is connected to the electromagnetic cover. The elastic force of the spring can more accurately control the telescopic travel of the vibrating diaphragm, thereby effectively regulating the instantaneous airflow pressure and ensuring that sputum can be fully removed.

[0012] Preferably, the inner wall of the cavity is provided with a corrugated groove. When the vibrating diaphragm expands and contracts, the corrugated groove can increase the turbulent effect of the airflow, which helps to increase the instantaneous pressure peak of the airflow.

[0013] Preferably, the air outlet is provided at one end of the cavity and is provided with an extension tube.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The coughing machine of the utility model uses a percussion structure to solve the problem that the existing suction machine has insufficient air source pressure and cannot guarantee the suction effect. It adopts magnetic drive with fast response time, can instantly change the volume of the variable chamber, effectively improve the air outlet pressure, thereby improving the suction efficiency, and facilitating the discharge of sputum from patients. Reinforcing ribs are provided on the vibrating diaphragm, which are evenly distributed on the vibrating diaphragm, thereby enhancing the reset ability and service life of the vibrating diaphragm. By adding a spring to the telescopic drive mechanism, it is ensured that the vibrating diaphragm can be quickly reset after the magnetic repulsive force disappears, avoiding the reset problem caused by insufficient airflow pressure. The design of the corrugated groove increases the turbulent effect of the airflow, helps to increase the instantaneous airflow pressure peak, and thus enhances the suction effect. A sealing ring is provided on the edge of the vibrating diaphragm to ensure that there is no air leakage during the telescopic process, ensure that a high-pressure area is formed inside the cavity, and improve the suction effect.

For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1 to 3 As shown, the percussion structure of the expectorant in this embodiment includes an output end cover 5, a cavity 50 is arranged in the output end cover 5, an air inlet 51 and an air outlet 52 are arranged on the output end cover 5, a vibration diaphragm 4 is arranged at one end of the output end cover 5, the vibration diaphragm 4 and the cavity 50 are combined to form a variable chamber, the vibration diaphragm 4 can be retractably arranged in the cavity 50, and one end of the vibration diaphragm 4 is connected to a telescopic driving mechanism, which drives the vibration diaphragm 4 through the telescopic driving mechanism to change the volume of the variable chamber.

[0029] The telescopic drive mechanism includes a mounting plate 11 and a transmission rod 3 that slidably engages with the mounting plate 11. The mounting plate 11 is connected to the output end cap 5. The edge of the vibrating diaphragm 4 is connected to the mounting plate 11. One end of the transmission rod 3 is connected to the center of the vibrating diaphragm 4, and the other end of the transmission rod 3 is connected to an extension structure. Multiple connection points can be set at the center of the vibrating diaphragm 4, and one end of the transmission rod 3 is mounted on the connection point. One end of the transmission rod 3 can be a sheet-like structure that mates with the vibrating diaphragm 4 to ensure that the vibrating diaphragm 4 maintains good concentricity during the telescopic process.

[0030] The mounting plate 11 is provided with a balancing air hole 111. The vibrating diaphragm 4 will generate a negative pressure during operation, and the balancing air hole 111 is provided to ensure smooth movement.

[0031] The extended structure includes a transmission end cover 1, which is connected to the mounting plate 11. A motion cavity is set in the transmission end cover 1, and a permanent magnet 12 is set in the motion cavity. An electromagnetic cover 2 is slidably set outside the permanent magnet 12, and the electromagnetic cover 2 is connected to the transmission rod 3.

[0032] The vibration diaphragm 4 is made of silicone material. The air outlet 52 is provided at one end of the cavity 51 and an extension tube 54 is provided.

[0033] When this embodiment is in use, the fan is connected to the air inlet 51. Under normal circumstances, the air flow enters the cavity 50 from the air inlet 51 and is then discharged from the air outlet 52. This embodiment changes the volume of the variable chamber instantly, and then changes the outlet pressure, which is conducive to suctioning. Specifically, the electromagnetic cover 2 is energized. The electromagnetic cover 2 is composed of a coil. When energized, a magnetic field is generated. When the magnetic pole is different from the permanent magnet 12, the electromagnetic cover 2 is pushed by the repulsive force, and then drives the transmission rod 3 to move. The transmission rod 3 drives the vibrating diaphragm 4 to extend into the cavity 50, quickly compressing the volume of the variable chamber, so that the air pressure increases and is discharged from the air outlet 52 to drive the suction machine. After exhausting, the vibrating diaphragm 4 contacts the extension tube 54, the electromagnetic cover 2 is powered off, the magnetic repulsive force disappears, and as air enters the air inlet 51, the vibrating diaphragm 4 is reset. When the time interval between power on and off is very short, multiple oscillations can be achieved in a short period of time, thereby achieving a more efficient coughing function.

[0034] Example 2

[0035] like Figure 4 As shown, in order to increase the service life of the vibration diaphragm 4 and enhance the reset capability, the vibration diaphragm 4 is provided with reinforcing ribs 40, which are evenly distributed on the vibration diaphragm 4. This is beneficial for the reset of the vibration diaphragm 4.

[0036] Example 3

[0037] like Figure 5 As shown, to prevent airflow pressure from preventing the vibrating diaphragm 4 from returning to its original position, the telescopic drive mechanism of this embodiment also includes a spring 31. One end of the spring 31 is fixed to the mounting plate 11, and the other end is connected to the electromagnetic cover 2. After the magnetic repulsion disappears, the spring 31's elastic force quickly resets the diaphragm. The spring force 31 is smaller than the magnetic repulsion, ensuring the rapid pressurization function.

[0038] Example 4

[0039] like Figure 6 As shown, the inner wall of the cavity 50 is provided with a corrugated groove 501. When the vibrating diaphragm expands and contracts, the corrugated groove can increase the turbulence effect of the airflow, which helps to increase the instantaneous pressure peak of the airflow.

[0040] It should be noted that a sealing ring may be provided at the edge of the vibrating diaphragm 4 to ensure that the edge does not leak during the expansion and contraction process of the vibrating diaphragm 4, thereby ensuring that a high-pressure area is formed inside the cavity 50. Filters may also be provided at the air inlet 51 and the air outlet 52 to prevent external impurities from entering the cavity 50.

[0041] The above is only an embodiment of the present invention, and common knowledge such as the specific structure and characteristics of the scheme are not described in detail here. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is limited by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claim involved.
