Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and more specifically, to a high-frequency generator and a high-frequency ventilator. Background Technology
[0002] A high-frequency ventilator is a medical device that can replace the body's spontaneous ventilation function. It provides ventilation through a higher respiratory rate and extremely low tidal volume, and is suitable for patients with open lung wounds and severe air leaks. The high-frequency generator is the core component of a high-frequency ventilator and is the key device for realizing high-frequency oscillating airflow. Currently, it generally generates oscillating airflow by driving the diaphragm in a closed cavity to move bidirectionally through the reciprocating motion of a motion shaft.
[0003] However, during prolonged, high-intensity reciprocating motion, the motion shaft experiences continuous friction with components such as bearings and seals. This friction leads to gradual wear of the parts and may even cause material fatigue. Over time, the accumulation of wear and fatigue causes a decrease in the precision of the motion shaft, which in turn affects the bidirectional movement of the diaphragm, resulting in a reduction in the performance of the high-frequency generator. Furthermore, the reciprocating motion of the motion shaft generates heat, especially during high-intensity operation. If the cooling system cannot effectively dissipate this heat, the internal temperature of the high-frequency generator will rise. High temperatures not only accelerate the wear and aging of mechanical components but may also cause malfunctions in electronic components, thus affecting the overall performance of the high-frequency generator. Therefore, current high-frequency generators may experience mechanical failures or performance degradation under prolonged, high-intensity operation. Summary of the Invention
[0004] The problem solved by this invention is: how to design a high-frequency generator to avoid the wear, failure and heat dissipation problems caused by the reciprocating motion of the motion shaft in traditional high-frequency generators.
[0005] To address the above problems, the present invention provides a high-frequency generator.
[0006] In a first aspect, the present invention provides a high-frequency generator, comprising: a housing, wherein the housing has a chamber having an air inlet and an air outlet, the chamber has a flexible transmission tube connecting the air inlet and the air outlet, the chamber has at least one roller assembly, the roller assembly is connected to a drive assembly, the drive assembly includes a turntable and a drive member, the turntable is disposed in the chamber, the output shaft of the drive member extends into the chamber and is drivenly connected to the center of the turntable, the transmission tube is disposed around the turntable, the roller assembly is disposed along the outer periphery of the turntable and is used to press the transmission tube, the drive member is used to drive the turntable to rotate, thereby driving the roller assembly pressed on the transmission tube to move along the transmission tube from the air inlet to the air outlet, squeezing the transmission tube to generate an oscillating airflow.
[0007] Optionally, the roller assembly includes a roller support frame and oscillating rollers connected to both ends of the roller support frame. The roller support frame is connected to the turntable and extends along the transmission pipe from the air inlet to the air outlet. The oscillating rollers are used to press the transmission pipe.
[0008] Optionally, both ends of the roller support frame are provided with arc-shaped grooves corresponding to the oscillating rollers, and the oscillating rollers are slidably connected in the arc-shaped grooves.
[0009] Optionally, a telescopic assembly is connected between the roller support frame and the turntable. The telescopic assembly includes a driver, a crank, and a connecting rod. One end of the driver passes through the turntable and is connected to the crank. The end of the crank away from the driver is connected to the connecting rod. The end of the connecting rod away from the crank is connected to the roller support frame. The driver is used to drive the crank to rotate, thereby driving the roller support frame to move back and forth towards or away from the transmission tube via the connecting rod.
[0010] Optionally, a guide unit is provided between the connecting rod and the roller support frame. The guide unit includes a guide rod and a guide block. One end of the guide rod is connected to the end of the connecting rod away from the crank, and the other end of the guide rod is connected to the middle of the roller support frame in the extending direction. The guide block is connected to the turntable and has a guide groove that extends radially along the turntable. The guide rod is slidably connected in the guide groove.
[0011] Optionally, one end of the output shaft of the drive unit passes through the turntable, and the output shaft is connected to a bushing and a retaining ring on both sides of the turntable, with the bushing and the retaining ring abutting against the side wall of the turntable.
[0012] Optionally, the inner wall of the chamber is provided with at least one support block, the support block is arranged along the extension direction of the transmission pipe from the air inlet to the air outlet, and the support block abuts against the lower end of the transmission pipe.
[0013] Optionally, the housing is connected to a first pipe connector and a second pipe connector. The first pipe connector is located outside the air inlet and communicates with the chamber. The second pipe connector is located outside the air outlet and communicates with the chamber. Both the first pipe connector and the second pipe connector are connected to the outer wall of the chamber through a fixing block.
[0014] Optionally, the chamber is equipped with a cooling fan, and the side wall of the chamber is provided with several heat dissipation holes.
[0015] The beneficial effects of the high-frequency generator of the present invention are as follows: The high-frequency generator includes a chamber with an air inlet and an air outlet, and a flexible transmission pipe is installed in the chamber, connecting the air inlet and the air outlet. At least one roller assembly is also provided in the chamber, capable of pressing against the transmission pipe. The roller assembly is driven by a drive assembly, which includes a turntable and a drive member. The turntable is disposed in the chamber, and the output shaft of the drive member extends into the chamber and is drively connected to the center of the turntable. The roller assemblies are spaced circumferentially around the outer periphery of the turntable. When the drive member is activated, it drives the turntable to rotate. As the turntable rotates, the roller assemblies on it move along the transmission pipe from the air inlet to the air outlet. During this process, the roller assemblies press and squeeze the transmission pipe. Due to the flexible nature of the transmission pipe, it deforms when squeezed by the roller assembly and returns to its original shape after the rollers pass. This periodic compression and recovery deformation generates an oscillating airflow within the transmission pipe, thereby achieving high-frequency ventilation.
[0016] Therefore, the high-frequency generator of this invention abandons the traditional reciprocating motion mode of the motion shaft, avoiding the friction and wear problems caused by long-term, high-intensity motion. Furthermore, driven by the rotation of the turntable, the roller assembly moves continuously and smoothly along the outer circumference of the turntable, ensuring that the roller assembly can continuously compress the flexible transmission tube, thereby generating a stable and continuous oscillating airflow. This also reduces friction with components such as bearings and seals, extending the service life of the equipment and reducing performance degradation and mechanical failures caused by wear and fatigue. Moreover, the rotational motion of the roller assembly is relatively simple, and the contact area between the roller assembly and the transmission tube is small, generating less heat. Simultaneously, by avoiding the reciprocating motion of the motion shaft, heat generated by friction is reduced, lowering the risk of mechanical component wear and electronic component failure due to high temperatures. In addition, the overall structure of the high-frequency generator of this invention is more compact, reducing space occupation. At the same time, due to the use of a turntable and roller assembly drive method, equipment maintenance is more convenient, reducing maintenance costs.
[0017] Secondly, the present invention provides a high-frequency ventilator, including any of the high-frequency generators described above, and having the beneficial effects of the high-frequency generators compared to the prior art, which will not be repeated here. Attached Figure Description

[0027] To address the problems existing in the aforementioned related technologies, this embodiment provides a high-frequency generator.
[0028] like Figure 1 , Figure 2As shown in the figure, an embodiment of the present invention provides a high-frequency generator, including a housing 1, a chamber 2 having an air inlet 21 and an air outlet 22 inside the housing 1, a flexible transmission pipe 3 connecting the air inlet 21 and the air outlet 22 inside the chamber 2, at least one roller assembly 4 inside the chamber 2, the roller assembly 4 being connected to a drive assembly 5, the drive assembly 5 including a turntable 51 and a drive member 52, the turntable 51 being disposed inside the chamber 2, the output shaft 521 of the drive member 52 extending into the chamber 2 and being drivenly connected to the center of the turntable 51, the transmission pipe 3 being disposed around the turntable 51, the roller assembly 4 being disposed along the outer periphery of the turntable 51 and used to press the transmission pipe 3, the drive member 52 being used to drive the turntable 51 to rotate, thereby driving the roller assembly 4 pressed on the transmission pipe 3 to move along the transmission pipe 3 from the air inlet 21 to the air outlet 22, squeezing the transmission pipe 3 to generate an oscillating airflow.
[0029] Specifically, the housing 1 is made of a robust and durable material with sufficient strength and rigidity to protect the internal mechanical and electronic components from damage caused by the external environment. The housing 1 includes a front cover and a rear cover, which are connected by snaps and screws to form a sealed chamber 2. The housing 1 has an air inlet 21 and an air outlet 22 communicating with the chamber 2 for gas input and output. The air inlet 21 can be connected to an external air source, and the air outlet 22 can be connected to other components of the high-frequency ventilator. The transmission tube 3 connecting the air inlet 21 and the air outlet 22 within the chamber 2 is made of a flexible material, such as rubber or silicone, with good elasticity and wear resistance. It can deform when squeezed by the roller assembly 4 and quickly return to its original shape after pressure release. The length and diameter of the transmission tube 3 can be adjusted according to actual needs to meet different ventilation requirements. The roller assembly 4 includes rollers and connectors. The rollers are made of a rigid material, such as metal or hard plastic, to ensure sufficient pressure is generated when extruding the transmission tube 3. The connectors connect the rollers to the turntable 51 and ensure the rollers remain stable during rotation. The number and spacing of the rollers can be adjusted according to actual needs to optimize the effect of the oscillating airflow. The drive unit 52 uses a power source such as a motor and is connected to the turntable 51 via an output shaft 521. The arrangement of the turntable 51 needs to be combined with the number and spacing of the roller assembly 4 to ensure that the roller assembly 4 can be moved evenly during rotation. In addition, the drive unit 5 also needs to have sufficient power and speed to meet the requirements of high-frequency oscillating airflow.
[0030] In this embodiment, during operation, the drive unit 52 starts and drives the output shaft 521 to rotate, which in turn drives the turntable 51 to rotate within the chamber 2. The roller assembly 4 rotates with the turntable 51 and moves along the transmission pipe 3 from the air inlet 21 to the air outlet 22, thereby moving and compressing the transmission pipe 3 to generate an oscillating airflow. By precisely controlling parameters such as the rotational speed of the drive unit 52, the diameter of the turntable 51, and the number and spacing of the roller assemblies 4, the frequency and amplitude of the oscillating airflow can be adjusted. By adjusting the rotational speed of the drive unit 52, the moving speed of the roller assembly 4 along the transmission pipe 3 is changed, thereby controlling the frequency of the oscillating airflow. The faster the rotational speed, the faster the roller assembly 4 moves, and the higher the oscillation frequency; conversely, the slower the rotational speed, the lower the frequency. By adjusting the pressure of the roller assembly 4 on the transmission pipe 3, the amplitude of the oscillating airflow can be controlled. The greater the pressure, the stronger the compression of the transmission pipe 3 by the roller assembly 4, and the larger the oscillation amplitude; conversely, the smaller the oscillation amplitude. Furthermore, the amplitude and pattern of the oscillation can be further influenced by adjusting the number of roller assemblies 4 and their distribution on the transmission pipe 3. When there is only one roller assembly 4, driven by the drive assembly 5, the roller assembly 4 moves along the transmission pipe 3 from the air inlet 21 to the air outlet 22. During this process, the roller assembly 4 periodically squeezes the transmission pipe 3, thereby generating an oscillating airflow. However, since there is only one squeezing point, the oscillation mode is relatively simple, and the frequency and amplitude of the airflow are mainly determined by the moving speed and pressure of the roller assembly 4, which is not precise enough. In this embodiment, multiple roller assemblies 4 are used. When multiple roller assemblies 4 are used, each roller assembly 4 can independently squeeze the transmission pipe 3, thereby generating multiple oscillation sources. This not only increases the complexity of the oscillation but may also improve the uniformity and efficiency of the oscillating airflow. The synergistic effect of multiple roller assemblies 4 can generate richer airflow patterns, which helps to achieve better results in some applications. Moreover, multiple roller assemblies 4 provide greater control flexibility. By independently controlling the moving speed, pressure, and relative position of each roller assembly 4, the frequency, amplitude, and mode of the oscillating airflow can be precisely adjusted. This flexibility allows the high-frequency generator to better adapt to different application scenarios and needs. In traditional high-frequency generators, the reciprocating motion of the shaft generates continuous friction with components such as bearings and seals, leading to gradual wear. However, the high-frequency generator in this embodiment uses the rotational motion of the turntable 51 and roller assembly 4 to compress the transmission tube 3, generating an oscillating airflow. This avoids the reciprocating motion of the shaft, reducing friction and wear and extending the equipment's lifespan. Furthermore, the rotational motion of the roller assembly 4 is relatively simple and generates less heat. Simultaneously, by avoiding the reciprocating motion of the shaft, heat generated by friction is reduced, minimizing the impact of high temperatures on mechanical and electronic components. Moreover, precise control of the turntable 51 and roller assembly 4 allows for uniform compression of the transmission tube 3, generating a stable oscillating airflow. This helps improve the performance stability of the high-frequency generator, making it more suitable for long-term, high-intensity working environments.Furthermore, compared to traditional high-frequency generators, the high-frequency generator in this embodiment generates oscillating airflow through the rotational motion of the turntable 51 and the roller assembly 4, which simplifies the structure and reduces manufacturing costs and maintenance difficulty.
[0031] Optionally, such as Figure 3 As shown, the roller assembly 4 includes a roller support frame 41 and an oscillating roller 42 connected to both ends of the roller support frame 41. The roller support frame 41 is connected to the turntable 51. The roller support frame 41 extends along the transmission pipe 3 from the air inlet 21 to the air outlet 22. The oscillating roller 42 is used to press the transmission pipe 3.
[0032] Specifically, the roller support frame 41 serves as the mounting base for the oscillating roller 42. Its shape can be straight, arc-shaped, or other to adapt to different shapes and arrangements of the transmission pipe 3. The material of the roller support frame 41 has sufficient strength and rigidity to withstand the forces and pressures generated by the roller assembly 4 during movement. The oscillating roller 42 is connected to both ends of the roller support frame 41 and is used to directly press and squeeze the transmission pipe 3. The material of the oscillating roller 42 has sufficient hardness and wear resistance to ensure that it will not wear excessively or be damaged during long-term use. Furthermore, the surface of the oscillating roller 42 can be designed with different shapes and textures to increase the friction and contact area with the transmission pipe 3, thereby improving the squeezing efficiency. The connection between the roller support frame 41 and the turntable 51 can be a hinge, a sliding connection, or other methods. The connection method should allow the roller support frame 41 to move along the length of the transmission pipe 3 when the turntable 51 rotates, while maintaining a certain degree of stability and reliability. To achieve precise adjustment of the frequency and amplitude of the oscillating airflow, an adjustment mechanism can be provided on the roller assembly 4. For example, the degree of compression and movement speed of the oscillating roller 42 on the transmission tube 3 can be changed by adjusting the connection angle or position between the roller support frame 41 and the turntable 51, thereby improving the flexibility and adaptability of the high-frequency generator and meeting different application requirements.
[0033] In this optional embodiment, when the drive component 52 of the drive assembly 5 is activated, it drives the turntable 51 to rotate. The roller support frame 41 is connected to the outer periphery of the turntable 51 and moves as the turntable 51 rotates. The movement of the roller support frame 41 drives the oscillating rollers 42 at both ends to move along the transmission pipe 3 from the air inlet 21 to the air outlet 22, and presses the transmission pipe 3 during the movement. The pressing and releasing of the transmission pipe 3 by the oscillating rollers 42 causes the gas in the transmission pipe 3 to be periodically compressed and released, thereby generating an oscillating airflow. The roller support frame 41 provides stable support for the oscillating rollers 42, ensuring the stability and reliability of the roller assembly 4 during the movement, and reducing damage or performance degradation of the transmission pipe 3 caused by the shaking or displacement of the oscillating rollers 42. The oscillating rollers 42 directly press the transmission pipe 3, and through the precise movement of the roller support frame 41, uniform compression of the transmission pipe 3 can be achieved, improving compression efficiency and helping to generate a more stable and efficient oscillating airflow. The roller assembly 4 has a relatively simple structure and is easy to disassemble and replace. When the oscillating roller 42 is worn or damaged, a new roller can be easily replaced without replacing the entire drive assembly 5 or the high-frequency generator. The roller support frame 41 and the oscillating roller 42 can be adjusted according to different application requirements. For example, the length of the roller support frame 41 can be changed to accommodate transmission pipes 3 of different lengths, or the material and hardness of the oscillating roller 42 can be changed to adapt to different working environments and gas types.
[0034] Optionally, such as Figure 3 As shown, both ends of the roller support frame 41 are provided with arc-shaped grooves 411 corresponding to the oscillating rollers 42, and the oscillating rollers 42 can be slidably connected in the arc-shaped grooves 411.
[0035] Specifically, the roller support frame 41 serves as the mounting base for the oscillating roller 42, and its two ends are provided with arc-shaped grooves 411, within which the oscillating roller 42 can be slidably connected. The curvature of the arc-shaped grooves 411 should be precisely designed according to the shape of the transmission pipe 3 and the extrusion requirements to ensure that the oscillating roller 42 can remain stable and produce a uniform extrusion effect during sliding. The material of the arc-shaped grooves 411 should have sufficient strength and wear resistance to withstand the force and friction generated by the roller during sliding. The roller support frame 41 has arc-shaped grooves 411, and the oscillating roller 42 is fixed to the roller support frame 41 by nuts and washers. Adjustments can be made during roller installation by moving the oscillating roller 42 within a certain range within the arc-shaped grooves 411 to adjust the distance between the two oscillating rollers 42. Minor sliding adjustments can also be made within the arc-shaped grooves 411 during rotation to adapt to different extrusion requirements. To further improve the adaptability and flexibility of the roller assembly 4, an adjustment mechanism can be provided on the roller support frame 41. For example, the degree of compression and movement speed of the oscillating roller 42 on the transmission tube 3 can be changed by adjusting the position of the oscillating roller 42 in the arc groove 411 or by adjusting the curvature of the arc groove 411, so as to make precise adjustments according to different application requirements to meet different compression requirements.
[0036] In this optional embodiment, when the drive component 52 of the drive assembly 5 drives the turntable 51 to rotate, the roller support frame 41 moves accordingly. The oscillating roller 42 slides within the arc-shaped groove 411, simultaneously pressing against the transmission pipe 3. Due to the presence of the arc-shaped groove 411, the oscillating roller 42 can automatically adjust its position relative to the transmission pipe 3 during movement, ensuring a more uniform extrusion effect. As the roller support frame 41 moves, the oscillating roller 42 moves along the transmission pipe 3 from the air inlet 21 to the air outlet 22, periodically pressing and releasing the transmission pipe 3 during movement to generate an oscillating airflow. The arc-shaped groove 411 allows the oscillating roller 42 to make minor sliding adjustments during movement, thereby better adapting to changes in the shape and position of the transmission pipe 3 and improving the uniformity of extrusion. The sliding connection mechanism reduces the wobbling and offset of the oscillating roller 42 during movement, enhancing the stability and reliability of the roller assembly 4. Furthermore, since the oscillating roller 42 can slide and adjust within the arc-shaped groove 411, excessive wear or damage caused by improper positioning is reduced, thereby extending the service life of the roller assembly 4. Moreover, the arc-shaped groove 411 and the sliding connection mechanism allow the roller assembly 4 to adapt to transmission tubes 3 of different shapes and sizes, improving the adaptability of the high-frequency generator.
[0037] Optionally, such as Figure 3 , Figure 4As shown, a telescopic assembly 6 is connected between the roller support frame 41 and the turntable 51. The telescopic assembly 6 includes a driver 61, a crank 62, and a connecting rod 63. One end of the driver 61 passes through the turntable 51 and is connected to the crank 62. The end of the crank 62 away from the driver 61 is connected to the connecting rod 63. The end of the connecting rod 63 away from the crank 62 is connected to the roller support frame 41. The driver 61 is used to drive the crank 62 to rotate, thereby driving the roller support frame 41 to move back and forth towards or away from the transmission tube 3 through the connecting rod 63.
[0038] Specifically, the driver 61, as a power source, can be a motor, cylinder, etc. One end of the driver 61 is connected to the outer periphery of the turntable 51 via bolts, etc., and the other end passes through the turntable 51 and is connected to the crank 62 via a flat key. A pad is provided between the driver 61 and the turntable 51. The driver 61 should be determined according to the operating environment and extrusion requirements of the high-frequency generator to ensure sufficient driving force and stability. The crank 62, as a transmission medium, should have its shape and size precisely designed according to the output characteristics of the driver 61 and the connection requirements of the connecting rod 63. One end of the crank 62 is connected to the driver 61, and the other end is connected to the connecting rod 63 via bolts or other connecting parts to ensure smooth transmission of rotational motion. The connecting rod 63 is used to transmit the reciprocating motion of the crank 62, driving the roller support frame 41 to move. The shape and size of the connecting rod 63 should be precisely designed according to the moving trajectory of the roller support frame 41 and the extrusion requirements. One end of the connecting rod 63 is connected to the crank 62 via a pin or other connecting part to ensure smooth transmission of linear motion. Connecting components such as pins and bolts are used to connect parts such as the drive unit 61, crank 62, connecting rod 63, and roller support frame 41. The selection and installation of connecting components should ensure the stability and reliability of the transmission and avoid malfunctions such as loosening or breakage.
[0039] In this optional embodiment, when the driver 61 is started, it drives the crank 62 to rotate. The rotation of the crank 62 is converted into linear motion of the roller support frame 41 through the connecting rod 63, that is, the roller support frame 41 moves towards or away from the transmission tube 3. During operation, the driver 61 drives the crank 62 and the connecting rod 63 to extend the oscillating roller 42 outward and press it against the transmission tube 3. When not in operation, the oscillating roller 42 is retracted inward and away from the transmission tube 3 to avoid the transmission tube 3 being in a pressed state for a long time and to reduce wear.
[0040] Optionally, such as Figure 3As shown, a guide unit 7 is provided between the connecting rod 63 and the roller support frame 41. The guide unit 7 includes a guide rod 71 and a guide block 72. One end of the guide rod 71 is connected to the end of the connecting rod 63 away from the crank 62, and the other end of the guide rod 71 is connected to the middle of the roller support frame 41 in the extending direction. The guide block 72 is connected to the turntable 51, and a guide groove 721 is provided on the guide block 72. The guide groove 721 extends radially along the turntable 51, and the guide rod 71 is slidably connected in the guide groove 721.
[0041] Specifically, the guide rod 71 serves as a guide for the movement of the roller support frame 41. Its shape and size should be precisely designed according to the movement trajectory and compression requirements of the roller support frame 41. One end of the guide rod 71 is connected to the connecting rod 63 via a connector (such as a pin, bolt, etc.), and the other end is connected to the middle of the extension direction of the roller support frame 41 to ensure that the roller support frame 41 remains stable during movement. The guide block 72 is connected to the outer periphery of the turntable 51 and has a guide groove 721. The shape and size of the guide groove 721 should match the guide rod 71 to ensure that the guide rod 71 can slide smoothly within the guide groove 721. The design of the guide groove 721 should consider the movement trajectory and compression requirements of the roller support frame 41 to ensure that the roller support frame 41 can move accurately to the predetermined position. Connectors such as pins, bolts, etc., are used to connect components such as the guide rod 71, the connecting rod 63, and the roller support frame 41. The selection and installation of the connectors should ensure the stability and reliability of the transmission and avoid malfunctions such as loosening or breakage.
[0042] In this optional embodiment, when the driver 61 drives the crank 62 to rotate, the crank 62 pushes the guide rod 71 to slide along the guide groove 721 via the connecting rod 63. The sliding of the guide rod 71 within the guide groove 721 ensures that the roller support frame 41 moves smoothly along a predetermined trajectory, avoiding wobbling or deviation. Simultaneously, the sliding engagement between the guide rod 71 and the guide groove 721 also restricts the rotational freedom of the roller support frame 41, allowing it to move only along the direction of the guide groove 721. Therefore, the guide unit 7 ensures the stability of the roller support frame 41 during movement, avoiding transmission errors caused by wobbling or deviation. The sliding engagement between the guide rod 71 and the guide groove 721 improves the accuracy of the entire transmission system, enabling the roller support frame 41 to move more precisely to the predetermined position. Furthermore, the guide unit 7 reduces direct friction between the roller support frame 41 and the turntable 51, thereby reducing wear and noise and extending the service life of the equipment.
[0043] Optionally, such as Figure 4 As shown, one end of the output shaft 521 of the drive unit 52 passes through the turntable 51. The output shaft 521 is located on both sides of the turntable 51 and is connected to the bushing 522 and the retaining ring 523 respectively. The bushing 522 and the retaining ring 523 abut against the side wall of the turntable 51.
[0044] Specifically, the output shaft 521 of the drive component 52 passes through the turntable 51 and has sufficient strength and rigidity to transmit the required torque or force. A bushing 522 is installed on one side of the drive component 52 after the output shaft 521 passes through the turntable 51, and it abuts tightly against the side wall of the turntable 51. The bushing 522 is made of wear-resistant material to reduce friction and wear between it and the side wall of the turntable 51. A retaining ring 523 is installed on the other side of the bushing 522 and abuts tightly against the other side wall of the turntable 51. The main function of the retaining ring 523 is to prevent the bushing 522 from moving axially, ensuring a stable connection between the drive component 52 and the turntable 51. When the drive component 52 starts, its output shaft 521 begins to rotate and establishes a stable connection with the turntable 51 through the bushing 522 and the retaining ring 523. The tight abutment of the bushing 522 and the retaining ring 523 against the side wall of the turntable 51 ensures stable and efficient torque transmission between the drive component 52 and the turntable 51. Meanwhile, the design of bushing 522 and retaining ring 523 also reduces friction and wear between drive component 52 and turntable 51, extending the service life of the equipment.
[0045] In this optional embodiment, the axial movement of the turntable 51 is restricted by the bushing 522 and the retaining ring 523, ensuring accurate axial positioning between the drive member 52 and the turntable 51. Moreover, the tight contact between the bushing 522 and the retaining ring 523 and the side wall of the turntable 51 ensures a stable connection between the drive member 52 and the turntable 51, avoiding transmission errors caused by loosening or wear.
[0046] Optionally, such as Figure 2 As shown, the inner wall of the chamber 2 is provided with at least one support block 23. The support block 23 is arranged along the extension direction of the transmission pipe 3 from the air inlet 21 to the air outlet 22, and the support block 23 abuts against the lower end of the transmission pipe 3.
[0047] Specifically, the support block 23 is a block-shaped structure with a certain strength and rigidity. Its shape and size should match the shape and size of the transmission pipe 3 to ensure close contact and stable support between the two. Depending on the length, shape, and operational requirements of the transmission pipe 3, multiple support blocks 23 can be installed within the chamber 2. These support blocks 23 should be evenly distributed along the extension direction of the transmission pipe 3 from the air inlet 21 to the air outlet 22 to ensure stable support for the transmission pipe 3 at all locations.
[0048] In this optional embodiment, the support block 23 provides the necessary stable support for the transmission tube 3, ensuring that the transmission tube 3 maintains its predetermined position and shape under any operating conditions. Moreover, by providing additional constraints, the support block 23 prevents the transmission tube 3 from squeezing the rear shell and restricts the movement of the transmission tube 3. By limiting unnecessary movement of the transmission tube 3, the stability and reliability of the transmission tube 3 are ensured.
[0049] Optionally, such as Figure 2As shown, a first pipe connector 11 and a second pipe connector 12 are connected to the housing 1. The first pipe connector 11 is located outside the air inlet 21 and communicates with the chamber 2. The second pipe connector 12 is located outside the air outlet 22 and communicates with the chamber 2. Both the first pipe connector 11 and the second pipe connector 12 are connected to the outer wall of the chamber 2 through the fixing block 13.
[0050] Specifically, the first pipe connector 11 is located outside the air inlet 21 and is used to connect to an external fluid source to introduce fluid into the chamber 2. The second pipe connector 12 is located outside the air outlet 22 and is used to connect to an external discharge system or subsequent treatment equipment to discharge the fluid from the chamber 2. A fixing block 13 is used to connect the pipe connector to the outer wall of the chamber 2, ensuring a stable and airtight connection. The fixing block 13 is typically a structure with sufficient strength and rigidity to accommodate the connection requirements between the pipe connector and the chamber 2. When an external fluid source is connected to the air inlet 21 through the first pipe connector 11, fluid begins to enter the chamber 2. At this time, the connection between the first pipe connector 11 and the chamber 2 must be stable and airtight to prevent fluid leakage. Inside the chamber 2, after processing or transmission, the fluid is discharged through the air outlet 22. The connection between the second pipe connector 12 and the air outlet 22 also needs to be stable and airtight to ensure smooth fluid discharge and prevent leakage. The retaining block 13 plays a crucial role in both processes, ensuring a secure connection between the pipe fitting and the chamber 2 and preventing leakage problems caused by loose connections or poor sealing.
[0051] In this optional embodiment, the pipe fitting is connected to the outer wall of the chamber 2 by the fixing block 13, ensuring the stability and sealing of the connection and reducing the risk of fluid leakage. Moreover, the fixing block 13 increases the connection strength between the pipe fitting and the chamber 2, improves the stability of the entire system, and prevents failures or safety accidents caused by loose connections.
[0052] Optionally, a cooling fan is provided inside the chamber 2, and several heat dissipation holes are provided on the side wall of the chamber 2.
[0053] Specifically, when the cooling fan starts, it draws hot air out of chamber 2 or blows it towards the ventilation holes, thereby dissipating heat. The ventilation holes are located on the side wall of chamber 2, and their number and location are determined based on the heat distribution and cooling requirements within chamber 2. These holes allow hot air to flow out of chamber 2 while allowing external cool air to enter, creating convection and accelerating heat dissipation. When the cooling fan starts, the generated airflow accelerates the flow of hot air within chamber 2, causing it to flow out of chamber 2 through the ventilation holes. Simultaneously, external cool air enters chamber 2 through the ventilation holes, replenishing the exhausted hot air and creating a convection cycle. This process continues until the temperature inside chamber 2 drops to a safe range.
[0054] In this optional embodiment, the combination of a cooling fan and heat dissipation holes can significantly improve the heat dissipation efficiency within chamber 2, reduce the operating temperature of the equipment or components, and extend their service life. Furthermore, effective heat dissipation ensures the normal operation of the equipment or components within chamber 2, preventing malfunctions or performance degradation due to overheating, and improving the stability and reliability of the entire system.
