For example, they may be fixedly connected, detachably connected, integrally connected, mechanically connected, electrically connected, directly connected, indirectly connected through an intermediate medium, or even a communication inside two components. Those skilled in the art may understand the specific meanings of the above terms in the present application according to specific situations.

[0021] Referring together to Figures 1 and 2, a first embodiment of the present application provides a washable handle 10 for use in a pulse therapy device, the washable handle 10 comprising a handle body 11, a ventilation circuit 12, a filter chamber 13, a pulse generator 14, a gas output component 15, and a sensor component 16, wherein the handle body 11 is the main body portion grasped by the user and is a connecting structure for securing the ventilation circuit 12, the filter chamber 13, the pulse generator 14, the gas output component 15, and the sensor component 16, the handle body 11 being detachably connected to the ventilation circuit 12, the filter chamber 13, the pulse generator 14, and the gas output component 15 by connecting means such as snaps, screws, or quick-release interfaces, and the handle body 11 is used to secure and protect the sensor component 16. The ventilation circuit 12, filter chamber 13, pulse generator 14, and gas output component 15 are sequentially connected to form an air supply path for the washable handle 10. The filter chamber 13, pulse generator 14, and gas output component 15 are detachably connected to the handle body 11. Furthermore, by removing each of the above components from the handle body 11, comprehensive cleaning and disinfection can be performed. This avoids the problem of bacteria and impurities remaining if the components are integrally mounted on the handle body 11 and cannot be disinfected or cleaned without removal, ensuring safe use, avoiding cross-infection, and eliminating the need to replace the entire handle body 11 as needed. Any of the components can be replaced, maintained, or repaired, thereby reducing operating costs and maintenance difficulty. The sensor component 16 is located on the handle body 11, and the ventilation circuit 12 is used to connect to a compressed gas source. The air inlet end of the ventilation circuit 12 is connected to the compressed gas source via a hose or fixed port, receiving the compressed airflow provided by the compression mechanism and transmitting the compressed airflow to the filter chamber 13. The filter chamber 13 is used to filter out impurities and particles from the compressed airflow, ensuring that the gas entering the pulse generator 14 is clean and uncontaminated. The filter chamber 13 can be separated from the handle body 11 for easy cleaning and replacement.A communication port is provided at the bottom of the filter chamber 13 and is connected to a sensor component 16 on the handle body 11. The sensor component 16 is used to detect the pressure or velocity of the airflow in the filter chamber 13. It should be noted that the filter chamber 13 does not affect the permeability of the chemicals. The pulse generator 14 is used to convert the compressed airflow into a pulsed airflow, which is transmitted to the user via the gas output component 15. The sensor component 16 communicates with the filter chamber 13 and is used to detect the airflow parameters in the filter chamber 13.

[0022] Furthermore, referring to Figure 3 in conjunction with this, in some preferred embodiments, a filter mounting portion 111 and an air pipe fixing portion 112 are provided at the top of the handle body 11. The filter mounting portion 111 has a semi-annular groove structure, and an elastic sealing ring is provided on its inner wall, forming an airtight connection with the lower chamber body 132 of the filter chamber 13. This provides a clear positioning reference when attaching and detaching the filter chamber 13 and the air pipe member, reducing the risk of misinstallation and misalignment. Each member can be quickly reset even after multiple washes or maintenance cycles, reducing maintenance time and difficulty.

[0023] The filtration chamber 13 includes an upper chamber body 131, a lower chamber body 132, a filtered air inlet 133, and a filtered air outlet 134. After the compressed airflow enters the filtration chamber, solid impurities and particles are effectively removed, ensuring the cleanliness of the airflow transmitted to the pulse generator 14, protecting subsequent components, and enhancing the therapeutic effect. The lower chamber body 132 is detachably locked and sealed to the filtration mounting section 111, forming a filtration chamber. The filtration chamber is provided with a number of filter cartridge structures, which communicate with the sensor component 16. The upper chamber body 131 and the lower chamber body 132 of the filtration chamber 13 are detachably locked, and the filter cartridge structures are provided within the filtration chamber, making it easier to replace and clean the filter cartridges. If the resistance increases or the filtration accuracy decreases after the filter cartridge has been used for a certain period of time, the user can quickly remove the lower chamber body 132 to clean or replace the filter cartridge, thus maintaining stable airflow quality over long periods of use. At the same time, the filtration chamber is in communication with the sensor component 16, and the sensor can monitor the gas state after filtration in real time. This allows the device to detect problems early, before impurities accumulate or the performance of the filter cartridge deteriorates, and ensure the continuous stability of the airflow parameters.

[0024] The filtered air inlet 133 is provided in the upper storage body 131 and is used to connect to the ventilation circuit 12. By providing the filtered air inlet 133 above the upper storage body 131, gravity and the natural distribution of airflow direction are utilized to filter the compressed airflow through the filter cartridge layer before it enters the downstream components, ensuring that the filter cartridge surface is always in good working condition after cleaning and reducing the probability of damage to the filter cartridge during the installation and removal process.

[0025] The filtered air outlet 134 is detachably connected to the air pipe fixing part 112 and used to connect to the pulse generator 14. By designing a detachably connected interface at the location of the filtered air outlet 134, the filtered gas can be flexibly introduced into the pulse generator 14. If the pulse generator 14 or the air outlet pipe needs to be cleaned or replaced, the pulse generator 14 can be removed independently without disassembling other components, which can reduce equipment downtime in frequently used environments and improve the operational efficiency of the crisis in medical facilities.

[0026] As can be seen from the above, the lower chamber body 132 and the handle body 11 of the filtration chamber 13 are detachably locked and sealed by the filtration mounting part 111, making it convenient to quickly disassemble the filtration chamber 13, facilitating cleaning of the filtration chamber and replacement of the filter cartridge, effectively solving the problem of difficulty in disinfecting and cleaning the non-detachable handle in the prior art, and efficiently sealing and connecting the filtration chamber and the handle body 11 via the sealing structure (seal ring, etc.) inside the filtration mounting part 111, preventing gas leakage even in a high-pressure airflow environment.

[0027] Referring in conjunction with Figures 4 to 7, in some preferred embodiments, the height of the filter mounting section 111 is lower than that of the air pipe fixing section 112, and a mounting platform is provided on the filter mounting section 111. A U-shaped recessed groove 113 is provided on the mounting platform, and the opening direction of the U-shaped recessed groove 113 is spaced apart from the air pipe fixing section 112. The U-shaped recessed groove 113 has a groove bottom 1131, a first side groove wall 1132, an arc-shaped side groove wall 1133, and a second side groove wall 1134. A sensing docking hole 1135 is provided at the position of the groove bottom 1131, and communicates with the filter chamber 13, provided that the sensor component 16 does not interfere with other members. By providing restrictive slide grooves 1136 in the first and second side channel walls 1132 and 1134, precise guidance and restriction can be achieved when installing the lower storage body 132, and the arc-shaped transition structure of the arc-shaped side channel wall 1133 can reduce the probability of damage due to mutual friction between members during the attachment and detachment process. Furthermore, to provide a stable spatial positioning foundation for the installation, alignment, and sealing of the filtration storage 13, high-precision docking can be maintained even after several filter cartridge replacements and cleaning operations, ensuring high sealing performance and sensing / detection accuracy of the device during long-term use.

[0028] A bundling opening 1321 is provided at one end of the lower storage body 132 away from the upper storage body 131, and an axial tapered portion 1322, an axial constant diameter portion 1323, and an inner diameter receiving portion 1324 are sequentially provided at the bundling opening 1321. Two locking structures 1325 are symmetrically distributed on the outer surface of the axial constant diameter portion 1323, and an anti-slip member 18 is positioned between the two locking structures 1325. By aligning the lower storage body 132 with the limiting slide groove 1136 via the locking structures 1325, when the lower storage body 132 is inserted along the U-shaped recessed groove 113, the locking structures 1325 slide along the limiting slide groove 1136 to a predetermined position, can be constrained by the height restriction, and a stable and reproducible sealed connection is formed at the appropriate position. The presence of the anti-loosening member 18 prevents accidental loosening of the lower chamber body 132 under high-pressure airflow or long-term use conditions, reducing the complexity of secondary assembly alignment while maintaining long-term sealing quality, and preventing the lower chamber body 132 from coming off along the limiting slide groove 1136. When the axial diameter constant portion 1323 is inserted into the sensing docking hole 1135, the filtration chamber 13 and sensor component 16 exchange information in a tightly fitted state, and the sensor docking process can be completed without the use of additional tools, simplifying the sensor fault diagnosis and maintenance workflow.

[0029] The fitting tolerance between the locking structure 1325 and the limiting slide groove 1136 can be optionally fine-tuned according to the material characteristics of the filter cartridge to address minute deformations of the components caused by changes in ambient temperature and humidity, thereby further protecting airtightness. Furthermore, the surface of the arc-shaped groove wall 1133 may be coated with an abrasion-resistant coating or made of a material with a low coefficient of friction to reduce wear from long-term attachment and detachment, and to maintain stable and easily maintainable structural characteristics under long-term operating conditions.

[0030] Furthermore, an anti-detachment structure 1326 is provided on the outer surface of the axial diameter constant portion 1323, and the anti-detachment structure 1326 is provided between the two locking structures 1325, and the anti-detachment structure 1326 is locked to the anti-detachment member 18, and when removing the filter chamber 13, the anti-detachment member 18 is pushed down or lifted, thereby detaching the anti-detachment member 18 from the anti-detachment structure 1326, thereby making it easy to remove the filter chamber 13.

[0031] Referring in conjunction with Figures 8 and 9, in some preferred embodiments, the pulse generator 14 includes a pulse housing 141, a motor, a first magnetic rotor and a second magnetic rotor 144 to achieve pulse modulation of the airflow. The pulse housing 141 includes a pulse spacer 1411 and a motor mounting plate 1412 provided between the pulse spacer 1411 and the handle body 11. By adding the motor mounting plate 1412 between the pulse spacer 1411 and the handle body 11, the motor can be easily maintained and replaced in an independent mounting space, and the stability and precision of the motor components can be ensured even after operating for a certain period of time. The pulse spacer 1411 is provided with a pulse air inlet 1413, a pulse exhaust port 1414 and a pulse rotation shaft 1415. The pulse air inlet 1413 is connected to a filtered air outlet 134. By directly connecting the pulse air inlet 1413 to the filtered air outlet 134, purified gas from the filtered chamber 13 is allowed to enter the pulse generator 14, reducing wear of the pulse members due to solid impurities and ensuring gas quality during the pulse modulation process. The pulse exhaust port 1414 is used to guide the pulse-modulated gas downstream or to the exhaust path, and to discharge residual gas and exhaust gas in an orderly manner. The motor is located on the side of the motor mounting plate 1412 away from the pulse spacer 1411. By positioning the motor away from the pulse spacer 1411, the effects of heat and vibration on the motor during actual operation are more easily dispersed, interference with the magnetic coupling state between the pulse rotation shaft 1415 and the magnetic rotor is reduced, and the control stability of the pulse frequency can be improved. The first magnetic rotor is located on the output shaft of the motor and is used to rotate in synchronization with the output shaft. By rotating the first magnetic rotor in synchronization with the motor output shaft, changes in the motor's rotational speed are directly converted into adjustments of the pulse frequency, achieving continuous modulation from low to high frequencies, and allowing the device to adapt to the treatment needs of different patients.The second magnetic rotor 144 is mounted on the pulse rotation shaft 1415 and is used to rotate in synchronization with the first magnetic rotor. It controls the pulse air inlet 1413 and pulse air outlet to open and close at a preset frequency. The magnetic coupling between the first and second magnetic rotors 144 enables stable synchronization of the fan-shaped rotating components during high-speed operation without mechanical contact, reducing bearing wear and energy consumption. At the same time, it maintains accurate opening and closing of the pulse air inlet 1413 and pulse air outlet even under high-pressure airflow, enabling high-precision therapeutic airflow adjustment. The pulse spacer 1411 has a rotation axis center, the pulse air inlet 1413 and pulse air outlet are located on the same circle with the rotation axis center as the center, and the pulse rotation axis 1415 is located on the rotation axis center. By distributing the pulse air inlet 1413 and pulse air outlet symmetrically on the same circumference and positioning the pulse rotation axis 1415 at the center, the load distribution on the rotating member during operation becomes more uniform, contributing to the maintenance of concentricity and rotational balance of the member during long-term operation, reducing vibration and deviation, and maintaining the stability and repeatability of the pulse output. A fitting gap 145 is provided between the motor mounting plate 1412 and the pulse air outlet to discharge exhaust gas discharged from the pulse air outlet. By leaving a fitting gap 145 between the motor mounting plate 1412 and the pulse air outlet, unused or excess gas during pulse modulation can be smoothly discharged, and unnecessary pressure accumulation inside the pulse housing 141 due to residual gas under high pressure conditions can be avoided. This design improves the safety and durability of the device.

[0032] Furthermore, in this embodiment, the thickness of the motor mounting plate 1412, the material of the pulse rotation shaft 1415, and the surface treatment of the magnetic rotor may be appropriately adjusted depending on the specific usage scenario. For example, to adapt to high-temperature sterilization environments, a more heat-resistant material for the motor mounting plate 1412 may be used, or corrosion protection treatment may be applied to the magnetic rotor surface, or stable pulse modulation performance may be maintained for a long period of time even under wet or airflow conditions containing trace amounts of drug particles.

[0033] In some preferred embodiments, the second magnetic rotor 144 includes a rotating shaft sleeve 1441, a first fan blade section 1442, and a second fan blade section 1443, wherein the rotating shaft sleeve 1441 is mounted on the pulse rotating shaft 1415 and is mounted in a manner that prevents detachment along the axial direction, so that during high-speed rotation and long-term operation, the rotating shaft sleeve 1441 does not experience axial sliding or loosening, and when the motor output shaft is driven to rotate the first magnetic rotor, the rotating shaft sleeve 1441 functions as a mounting member for the second magnetic rotor 144, rotating synchronously and maintaining coaxiality with the pulse rotating shaft 1415. Such a tight-fitting method allows for the maintenance of orthogonality and transmission stability of the rotating shaft even under high-frequency pulsed airflow conditions.

[0034] The first fan blade section 1442 and the second fan blade section 1443 are each provided at different circumferential positions on the rotating shaft sleeve 1441. Periodic opening and closing of the airflow can be achieved when the first fan blade section 1442 and the second fan blade section 1443 are alternately positioned relative to the pulse air inlet 1413 and the pulse air outlet. As the motor rotation speed changes, the alternating shielding behavior of these two fan blade sections changes the on / off time between the pulse air inlet 1413 and the pulse air outlet, thereby enabling flexible adjustment of parameters such as pulse frequency and pulse duty cycle.

[0035] By adopting a design in which two fan blades alternately open and close the air inlet and outlet passages, the flow rate and frequency modulation become more precise. For example, if a higher frequency pulse output is required at a certain motor speed, increasing the motor speed allows the two fan blades to operate alternately in a shorter time, thereby improving the frequency and stability of the pulse output. The structure, which does not require additional mechanical transmission members, simplifies the structure, reduces friction and energy loss, and improves the consistency and reliability of the pulse output.

[0036] Furthermore, the shape, size, and material of the fan blades can be appropriately optimized. For example, in high-humidity or airflow environments containing trace amounts of chemicals, corrosion-resistant and wear-resistant materials can be selected to create the fan blades and extend their service life, or a relatively linear pulse frequency response can be obtained at different motor speeds by adjusting the thickness and curvature of the fan blades.

[0037] Referring in conjunction with Figures 6, 10, and 11, in some preferred embodiments, the handle body 11 is further provided with a housing cavity 114 and a sensing seal plate 115 at a position corresponding to the sensing docking hole 1135, further enhancing the sealing and maintainability characteristics of the sensor component 16. By providing the sensing seal plate 115 at a position corresponding to the sensing docking hole 1135 in the housing cavity 114 and attaching the sensing seal plate 115 at the position of the sensing docking hole 1135 in the housing cavity 114, an independently controllable sealing space can be formed between the sensor component 16 and the filter chamber 13. When the sensor component 16 needs to be cleaned, replaced, or calibrated, it is not necessary to disassemble the handle body structure over a large area, and the sensor mounting area can be quickly accessed by appropriately manipulating only the sensing seal plate 115, thereby reducing maintenance time and simultaneously lowering the probability of errors and the difficulty of maintenance.

[0038] A sealing rib 1151 and a vent 1152 are provided on the sensing seal plate 115. The sealing rib 1151 is locked into the inner diameter receiving portion 1324 to seal it, and the sealing rib 1151 is provided on the sensing seal plate 115 and is locked into the position of the inner diameter receiving portion 1324, providing a highly reliable sealed port. Airtightness is ensured even when the airflow pressure changes or when it is washed several times, contributing to the cleaning and stability of the sensor measurement area. During long-term use and frequent maintenance, the presence of the sealing rib 1151 reduces airflow leakage and detection reading deviations due to small gaps, providing a reliable basic environment for sensor measurement.

[0039] The vent 1152 is provided on the end face of the sensing seal plate 115 located in the containment cavity 114 and communicates with the filtration chamber 13. By designing the vent 1152 on the sensing seal plate 115 and connecting this vent 1152 to the filtration chamber 13, the clean airflow after filtration can be allowed to flow into the containment cavity 114 where the sensor is located. In this way, the sensor can continuously receive the filtered and purified gas, thereby reducing interference to sensing accuracy due to particulate matter and humidity changes, and providing a good foundation for accurate measurements over long periods.

[0040] Furthermore, the relevant structures can be appropriately adjusted according to different clinical needs or cleaning specifications. For example, the diameter and length of the vent 1152 can be selected according to airflow characteristics and sensor sensitivity, allowing for a rapid response of the sensor under specific airflow velocity and pressure conditions. Alternatively, the sealing rib 1151 can be made of a high-temperature, chemically corrosion-resistant material, maintaining a stable sealing state even under high-temperature, high-pressure sterilization and disinfection conditions. In a real medical environment, the cleanliness and airtightness of the sensing area can be maintained for a long period, and the sensor component 16 can provide accurate and reliable measurement data even after frequent use or multiple disinfections.

[0041] Continuing to refer to Figure 11, in some preferred embodiments, the housing cavity 114 includes a sensor cavity 1141 and a component cavity 1142 that are isolated from each other, the sensor cavity 1141 communicating with the filter chamber 13 via the vent 1152, and the sensor component 16 is housed in the sensor cavity 1141. Dividing the housing cavity 114 into the sensor cavity 1141 and the component cavity 1142 ensures physical isolation between the sensor component 16 and component members such as the pulse generator 14. By separating the sensor cavity 1141 and the component cavity 1142, and providing an independent space in the housing cavity 114 for assembling the sensor component 16, other electronic components in the component cavity 1142 are sealed, thus avoiding contact with gas and preventing contamination. At the same time, when the sensor component 16 needs to be cleaned, replaced, or calibrated, it is not necessary to disassemble the handle body structure over a large area. By disassembling the sensing seal plate 115, the sensor mounting area can be quickly accessed, thereby reducing maintenance time and lowering the probability of errors and the difficulty of maintenance.

[0042] Simultaneously, the sensor cavity 1141 communicates with the filtration chamber 13 via the vent 1152, allowing the sensor to receive the clean airflow after filtration, thereby enabling real-time monitoring of airflow parameters, such as pressure and flow velocity. This isolation design effectively prevents the sensor from being affected by heat, vibration, or electromagnetic interference within the component cavity 1142, improving the accuracy and stability of the sensor's measurement data.

[0043] Referring again to Figure 11, in some preferred embodiments, the handle body 11 is further provided with an ultraviolet disinfection member 116, which is located in the sensor cavity 1141. By introducing the ultraviolet disinfection member 116 into the sensor cavity 1141, ultraviolet disinfection treatment can be performed inside the sensor cavity 1141 when the device is idle or undergoing periodic maintenance, thereby suppressing the growth of bacteria and pathogenic microorganisms. This maintains a clean measurement environment even during continuous use cycles, extends the service life of the sensor, and maintains measurement accuracy even in medical environments where bacteria are likely to grow, such as high humidity and high temperature.

[0044] Continuing to refer to Figure 11, in some preferred embodiments, a sealing spacer 117 is provided between the sensor cavity 1141 and the component cavity 1142, and the sensor component 16 can be detachably connected to the sealing spacer 117. When it is necessary to replace the sensor component 16, calibrate and maintain the sensor, or disinfect the sensor component 16, the entire machine does not need to be extensively disassembled, and the sensor component 16 can be quickly removed by disassembling only the sealing spacer 117, thereby reducing maintenance time and the probability of errors occurring. The method of connecting the sealing spacer 117 and the sensor component 16 can be selected from snap-type, screw-type, or magnetic-adsorption type, etc., to further improve operational convenience and maintenance efficiency, and the sensor component 16 can be electrically connected to the electronic components in the component cavity 1142 when it is assembled to the sealing spacer 117.

[0045] Referring again to Figures 1 and 4, in some preferred embodiments, the washable handle 10 is further provided with a data transmission component 17, which is used for power supply and data transmission, powers the sensor component 16 and pulse generator 14 via the data transmission component 17, and controls the sensor component 16 and pulse generator 14 via the data transmission component 17. At the same time, the washable handle 10 can also be communicated to a device host via the data transmission component 17.

[0046] Referring again to Figures 1 and 2, in some preferred embodiments, the gas output component 15 includes an occlusal portion 151, a sputum collection bottle 152, and a nose clip 153, where one end of the occlusal portion 151 is connected to the pulse generator 14, the other end of the occlusal portion 151 is used to connect to the user mouth, the sputum collection bottle 152 is detachably provided at the lower end of the occlusal portion 151, and the nose clip 153 is integrally molded at the upper end of the occlusal portion 151. Furthermore, the other end of the occlusal portion 151 is a user end 1511 for connecting to the user mouth, and a detachable occlusal sleeve 1512 is provided at the user end 1511, so that the occlusal sleeve 1512 can be replaced when used by different users, further avoiding cross-infection.

[0047] A second embodiment of this application provides a pulse therapy device comprising the washable handle described above, wherein the associated structure of the air passage can be removed and disinfected when different users use the handle of the pulse therapy device.

[0048] In summary, the present application provides a washable handle and a pulse therapy device, the washable handle comprising a handle body, a ventilation circuit, a filter chamber, a pulse generator, a gas output component, and a sensor component, the ventilation circuit, filter chamber, pulse generator, and gas output component being sequentially connected, the filter chamber, pulse generator, and gas output component being detachably connected to the handle body, the sensor component being provided on the handle body, the ventilation circuit being used to connect to a compressed gas source, the pulse generator being used to convert a compressed airflow into a pulsed airflow, the pulsed airflow being transmitted to a user via the gas output component, and the sensor component communicating with the filter chamber and being used to detect airflow parameters within the filter chamber. The washable handle features a detachable connection of the ventilation circuit, filter chamber, pulse generator, and gas output component to the handle body. This allows for comprehensive cleaning and disinfection of each component by removing them from the handle body. This avoids the problem of bacteria and impurities remaining due to the inability to remove and disinfect or clean these components as part of the handle body, thus ensuring safe use and preventing cross-infection. Furthermore, it eliminates the need to replace the entire handle body, allowing for the replacement, maintenance, or repair of any component as needed, thereby reducing operating costs and maintenance difficulty.

[0049] It should be understood that the application of this application is not limited to the examples given above, and that those skilled in the art may improve or modify the invention in accordance with the above description, and that all such improvements and modifications are included in the claims attached to this application.
