[0002] The tapping mechanism of existing full-chest high-frequency pulse sputum clearance devices has room for improvement in long-term use: (1) The structure in which the transmission component is directly connected to the tympanic membrane is difficult to maintain its initial parallel state during movement, which may affect the force distribution on the tympanic membrane; (2) The consistency of the connecting rod mounting structure on the eccentric shaft needs to be improved, which may lead to room for optimization of the synergy of the two tympanic membrane movements; (3) The fixed position distribution of the diaphragm and transmission components has a certain impact on the uniformity and effectiveness of power transmission, and there is potential for further optimization. Summary of the Invention

[0003] In order to solve the above problems, the purpose of this utility model is to provide a high-frequency pulse sputum clearance system for the whole chest cavity that keeps the tympanic membrane parallel, operates synchronously, and transmits power evenly.

[0004] According to one aspect of the present invention, a full-chest high-frequency pulse sputum clearance system is provided, comprising: a mounting base, a drive assembly, and an eccentric tapping assembly, the mounting base being connected to a housing at its bottom, the drive assembly being disposed within the base and connected to the eccentric tapping assembly, and the drive assembly controlling the operation of the eccentric tapping assembly; The eccentric striking assembly includes a first striking component, a second striking component, and an eccentric component. The bottom of the eccentric component is connected to a drive assembly. The first and second striking components are symmetrically mounted on the eccentric component, which drives the first and second striking components to perform linear reciprocating motion. By mounting on the support drive assembly and the eccentric striking assembly, the eccentric striking assembly ensures that the diaphragm remains parallel, operates synchronously, and that power is transmitted evenly.

[0005] In some embodiments, the eccentric component includes an eccentric shaft, a first transmission link, and a second transmission link. The bottom of the eccentric shaft is connected to the drive assembly via a coupling, the first transmission link is connected to the eccentric shaft via a bearing, and the top of the eccentric shaft is connected to the second transmission link via a bearing. The reciprocating alternating motion of the first and second striking components is achieved through the connection of the eccentric shaft to the first and second transmission links, ensuring synchronized operation.

[0006] In some embodiments, the mounting centerline of the first transmission link and the eccentric shaft is not collinear with the central axis of the coupling; the mounting centerline of the second transmission link and the eccentric shaft is not collinear with the central axis of the coupling; and the mounting centerlines of the first transmission link and the eccentric shaft are not collinear with the mounting centerlines of the second transmission link and the eccentric shaft. This eccentric shaft configuration ensures a stable transmission chain, resulting in synchronized diaphragm operation and uniform power transmission.

[0007] In some embodiments, the end of the first transmission link away from the eccentric shaft is hinged to the first striking component via a first hinge; The end of the second transmission link away from the eccentric shaft is hinged to the second striking component via the second hinge.

[0008] In some embodiments, the first striking component includes: a diaphragm, a pump housing, and a metal pressure ring, with an annular air chamber provided on the outer side of the pump housing, and the edge of the diaphragm fixed to the annular air chamber by the metal pressure ring; A connecting block is provided on the side of the pump casing away from the diaphragm, and the connecting block is hinged to the first transmission link via a first hinge. The pump utilizes a multi-stage transmission structure consisting of an eccentric shaft, transmission link, connecting block, and diaphragm. The connection surface between the connecting block and the diaphragm employs an adaptive structure to ensure the diaphragm maintains good parallelism during movement, reducing force deviation on the diaphragm, improving force distribution, and enhancing the smoothness of movement.

[0009] In some implementations, the tympanic membrane is made of an elastic material.

[0010] In some embodiments, the structure of the first striking component is the same as that of the second striking component.

[0011] In some implementations, the drive component is a servo motor or a stepper motor.

[0012] This invention offers advantages over existing technologies in maintaining diaphragm parallelism, synchronous operation, and uniform power transmission. By mounting the diaphragm on the support drive assembly and the eccentric striking assembly, the eccentric striking assembly ensures diaphragm parallelism, synchronous operation, and uniform power transmission. The eccentric shaft connects the first and second transmission links, enabling reciprocating alternating motion of the first and second striking components, ensuring synchronous operation. The eccentric shaft ensures a stable transmission chain, achieving synchronous diaphragm operation and uniform power transmission.

Detailed Implementation

[0014] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0015] In the description of this utility model, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the terms according to the specific circumstances.

[0016] like Figure 1 and Figure 2 As shown, the whole chest cavity high-frequency pulse sputum clearance system of this utility model includes: a mounting base 1, a driving component 2 and an eccentric tapping component 3. The mounting base 1 is connected to the outer shell at the bottom. The driving component 2 is set in the base and connected to the eccentric tapping component 3. The driving component 2 controls the operation of the eccentric tapping component 3. The eccentric striking assembly 3 includes a first striking component 31, a second striking component 32, and an eccentric component 33. The bottom of the eccentric component 33 is connected to the drive assembly 2. The first striking component 31 and the second striking component 32 are symmetrically mounted on the eccentric component 33, and the eccentric component 33 drives the first striking component 31 and the second striking component 32 to perform linear reciprocating motion. By mounting on the support drive assembly 2 and the eccentric striking assembly 3, the eccentric striking assembly 3 ensures that the diaphragm 311 remains parallel, operates synchronously, and that power is transmitted evenly.

[0017] like Figure 3As shown, the eccentric component 33 includes: an eccentric shaft 301, a first transmission link 302, and a second transmission link 303. The bottom of the eccentric shaft 301 is connected to the drive assembly 2 via a coupling 4. The eccentric shaft 301 is connected to the first transmission link 302 via a bearing, and the top of the eccentric shaft 301 is connected to the second transmission link 303 via a bearing. The reciprocating alternating motion of the first striking component 31 and the second striking component 32 is achieved through the connection of the eccentric shaft 301 with the first transmission link 302 and the second transmission link 303, ensuring synchronized operation.

[0018] The mounting center lines of the first transmission connecting rod 302 and the eccentric shaft 301 are not collinear with the central axis of the coupling 4. Similarly, the mounting center lines of the second transmission connecting rod 303 and the eccentric shaft 301 are not collinear with the central axis of the coupling 4. Furthermore, the mounting center lines of the first transmission connecting rod 302 and the eccentric shaft 301 are not collinear with the mounting center lines of the second transmission connecting rod 303 and the eccentric shaft 301. This arrangement of the eccentric shaft 301 ensures a stable transmission chain, resulting in synchronized operation of the diaphragm 311 and uniform power transmission.

[0019] The end of the first transmission link 302 away from the eccentric shaft 301 is hinged to the first striking component 31 via the first hinge 304. The end of the second transmission link 303 away from the eccentric shaft 301 is hinged to the second striking component 32 via the second hinge 305.

[0020] The specifications of the two connecting rod mounting holes on the eccentric shaft 301, and the fact that the two holes are symmetrically distributed in the same direction, ensure that the rotation center of the two connecting rods is symmetrical and concentric with the central axis of the eccentric shaft 301, ensuring that the movement trajectories of the two are completely synchronized (in the same direction and with the same amplitude); improve the synchronicity of the movement of the two tympanic membranes 311, keep the rhythm and amplitude of the compression and stretching movements on both sides highly consistent, and enhance the uniformity of treatment.

[0021] like Figure 4 As shown, the first striking component 31 includes: a diaphragm 311, a pump housing 312 and a metal pressure ring 313. An annular air chamber is provided on the outer side of the pump housing 312, and the edge of the diaphragm 311 is fixed to the annular air chamber by the metal pressure ring 313. A connecting block 314 is provided on the side of the pump housing 312 away from the diaphragm 311. The connecting block 314 is hinged to the first transmission link 302 via a first hinge 304. A multi-stage transmission structure consisting of an eccentric shaft 301, transmission link, connecting block 314, and diaphragm 311 is employed. The connection surface between the connecting block 314 and the diaphragm 311 adopts an adaptive structure to ensure that the diaphragm 311 maintains a good parallel state during movement, reducing force deviation on the diaphragm 311 during movement, improving the force distribution on the diaphragm 311, and enhancing the stability of movement.

[0022] The 311 tympanic membrane is made of elastic material.

[0023] The fixed position of the tympanic membrane 311 and the transmission component is adjusted to a central symmetrical point, and an optimized fixing method is adopted to ensure that the power transmission position is centered; so that the movement amplitude is transmitted more evenly to the entire tympanic membrane 311, increasing the effective air blowing area, and at the same time making the force on each area of ​​the tympanic membrane 311 more balanced, thus improving the overall performance.

[0024] The structure of the first striking component 31 is the same as that of the second striking component 32.

[0025] The drive component 2 is a servo motor or a stepper motor.

[0026] During implementation: When drive component 2 is activated, the output end of the motor drives the eccentric shaft 301 to rotate via coupling 4. Subsequently, the eccentric shaft 301 drives the first transmission link 302 and the second transmission link 303 to drive the connecting block 314 to move synchronously in the same direction. The connecting block 314 simultaneously pushes the left tympanic membrane 311 and the right tympanic membrane 311 (both fixed in the center) to bulge into the air chamber, and the left and right air chambers are compressed and inflated synchronously; at this time, excess gas can be discharged through the common air inlet (synchronous depressurization). After the eccentric shaft 301 rotates half a revolution, the connecting block 314 simultaneously pulls the left diaphragm 311 and the right diaphragm 311 back to the outside of the air chamber, and the left and right air chambers expand synchronously to draw in air; gas is synchronously drawn in through the shared air inlet to prepare for the next compression and inflation; The 311 tympanic membrane is kept in parallel motion by the central connecting rod throughout the process, the symmetrical opening specifications ensure synchronous action of the two cavities, and the central fixation improves the efficiency and uniformity of air blowing.

[0027] Compared with existing technologies, the transmission structure is more reasonable. Through the optimized design of the intermediate connecting rod, the motion state and force distribution of the diaphragm 311 are improved, and the motion stability is enhanced. With superior motion synchronization, the eccentric shaft 301 features a symmetrical opening design in the same direction, which enhances the consistency of the compression and stretching movements of the two tympanic membranes 311 and improves the uniformity of treatment. The power transmission is more efficient, and the centrally fixed design makes the motion transmission more uniform and effective, improving the blowing efficiency and overall performance of the equipment, and making it applicable to a wider range of scenarios.

[0028] This invention improves the stability of the tympanic membrane 311 movement. The optimized design of the intermediate transmission link ensures that the tympanic membrane 311 maintains a good parallel state during movement, resulting in a more reasonable force distribution and improved movement stability. The synchronization of the dual-cavity movement is enhanced. The symmetrical opening design of the eccentric shaft 301 improves the consistency of the compression and stretching movements of the two tympanic membranes 311, resulting in a more balanced inflation effect on both sides and better uniformity of treatment. The inflation efficiency is optimized. The centered power point allows for a more even coverage of the entire tympanic membrane 311, increasing the effective inflation area and improving inflation efficiency. Overall, the device's performance is improved. The force on each area of ​​the tympanic membrane 311 is more balanced, and the overall operation is more stable, contributing to improved device effectiveness and reliability.

[0029] The above descriptions are merely some embodiments of this utility model. It should be noted that those skilled in the art can make other modifications and improvements without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
