Description

Technical Field

[0001] This application relates to the field of respiratory therapy equipment technology, specifically a respiratory therapy device with an airflow regulation mechanism. Background Technology

[0002] Respiratory therapy equipment is widely used in clinical and home environments to provide patients with functions such as assisted breathing, humidification therapy, and nebulized drug delivery. Existing equipment typically includes an air supply system, a humidification device, and a nebulizer assembly. It delivers air to patients by mixing air with nebulized water vapor to improve airway humidification and drug delivery effectiveness.

[0003] However, existing respiratory therapy equipment still has many shortcomings in practical use. First, the exhaust fan in traditional equipment is usually directly connected to the outside, generating a lot of noise during operation, which seriously affects the patient's sleep quality during treatment. Second, the matching accuracy between air supply and nebulized water volume is low. When the air supply fluctuates, the humidification volume cannot be adjusted synchronously, which can easily lead to the output gas being too dry or too humid, causing patient discomfort and even causing water droplets to condense inside the breathing mask, affecting the user experience. Third, the mixing ratio of airflow and humidified vapor mostly depends on preset parameters, making it difficult to dynamically adjust in real time according to the actual airflow, resulting in unstable humidification effects. In addition, existing equipment is prone to generating excess water vapor during the humidification process, lacking an effective recycling mechanism, resulting in water waste. Furthermore, the equipment as a whole has not formed an adaptive closed-loop system, and its intelligence and stability need to be improved.

[0004] To address the aforementioned issues, there is an urgent need for a respiratory therapy device that can achieve low-noise operation, precise matching of air supply and humidification, dynamic synchronization of mixing ratio, and water vapor recovery function, in order to improve treatment comfort and overall device performance.

The unit is equipped with a motor, and an exhaust fan is installed at the output end of the motor. A water inlet is provided at the outer end of the water storage base.

An atomizing component is installed inside the air intake base, and a mixing component is installed inside the atomizing component. An air storage box is installed at the top outer end of the air intake base, and a return water pipe is connected between the air storage box and the atomizing component. A connector is provided at the top outer end of the air storage box.

[0007] Furthermore, the base assembly includes a base, a docking seat is disposed at the top outer end of the base, and air inlets are provided at both ends of the docking seat. A piston seat is disposed at the top outer end of the docking seat.

[0008] Furthermore, the inner contour of the docking seat matches the inner contour of the air intake seat, and the air intake seat is elastically connected to the docking seat through a return spring.

[0009] Furthermore, the outer contour of the piston seat matches the inner contour of the water storage seat, and the size of the vent groove is consistent with that of the air inlet.

[0010] Furthermore, the gas delivery assembly includes a gas storage bladder, with an air inlet pipe connected to the bottom outer end of the gas storage bladder and a second one-way air inlet valve installed in the middle section of the air inlet pipe. The top outer end of the gas storage bladder is connected to a vent pipe, with an electrically controlled valve installed in the middle section of the vent pipe.

[0011] Furthermore, the air intake pipe is connected to the interior of the air intake seat, and the air intake pipe is connected to the ventilation pipe through the air storage bag.

[0012] Furthermore, the atomizing component includes an atomizing box, an atomizer is installed at the bottom of the atomizing box, a partition plate is installed inside the atomizing box, and a liquid return groove is opened in the middle section of the partition plate. An atomizing tube is connected between the atomizing box and the air pipe.

[0013] Furthermore, the water storage base is connected to the atomizing box via a water supply pipe, and the atomizing box is connected to the air vent via an atomizing pipe.

[0014] Furthermore, the gas storage box is connected to the atomizing box via a return water pipe, and the gas storage box is also connected to the air vent pipe.

[0015] Furthermore, the mixing component includes a rotating tube, a wind turbine is mounted in the middle section of the rotating tube, and a spoiler is connected to one end of the rotating tube.

[0016] This application establishes a mechanical linkage structure between the base assembly and the air intake assembly to achieve synchronous matching of air supply and water supply. Specifically, the motor drives the exhaust fan to rotate, drawing air out of the cavity at the bottom of the air intake seat to create negative pressure. Under the action of the return spring, the air intake seat moves down along the docking seat, aligning the air intake port with the air inlet to complete air intake. During this process, the piston seat moves synchronously within the water storage seat along with the air intake seat, quantitatively pushing clean water into the atomizing box through the water supply pipe, and preventing backflow through a one-way water inlet valve. This structure makes the water supply and air intake positively correlated, achieving synchronous matching of air supply and atomized water volume. This provides a consistent input basis for the precise mixing of air and atomized water vapor in the future. In addition, in the above design, the exhaust fan draws air through intermittent air extraction, which avoids the high noise generated by direct air extraction. Furthermore, the exhaust fan is located in the middle of the air intake seat and surrounds the water storage seat on the outside, effectively blocking noise transmission and significantly improving the user's sleep quality during treatment.

[0017] 2. Based on the synchronous matching of air supply and water supply, this application further utilizes the airflow's own power to drive the mixing component, achieving synchronous ratio of air supply and humidification. The air storage bladder maintains a high-pressure state under continuous air supply. When the electronic control valve opens in response to the user's inhalation action, high-speed airflow flows through the ventilation pipe, driving the fan wheel to rotate, which in turn drives the rotating pipe and the baffle fan to rotate synchronously. The baffle fan is located below the atomizing pipe, and its rotation speed is directly related to the airflow. It sends the atomized water vapor generated by the atomizer into the ventilation pipe in proportion to mix with the air. This structure inherits the water and air volume matched in the previous stage of linkage, and achieves synchronous adjustment of humidification through the airflow's own power, so that the mixing ratio of air and water vapor remains stable during dynamic use.

[0018] 3. Based on the gas volume matching and proportional synchronization achieved by the first two stages of linkage, this application forms a closed-loop regulation of the gas supply and humidification structure through the energy recovery structure of the gas storage tank and the mixing component. The mixed humidified gas enters the inclined gas storage tank for temporary storage. During the temporary storage process, excess water vapor liquefies and collects at the lowest point. The fan wheel drives the spring box to store potential energy during rotation. When the airflow stops, the spring box releases potential energy to drive the return fan to rotate. The liquefied water at the bottom of the gas storage tank is pumped back to the atomizing box through the return water pipe, and then returned to the atomizer area for reuse through the return liquid tank. This structure recovers and reuses the excess water vapor generated in the first two stages of linkage, so that the equipment forms a complete adaptive closed loop between the three links of gas supply, humidification and recovery, further improving the stability of the equipment and the comfort of use.

[0022] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0024] Please see Figures 1 to 7 The respiratory therapy device with an airflow regulation mechanism provided in this application includes a base assembly 1, an air intake assembly 2, and a nebulizer assembly 6. The air intake assembly 2 is housed inside the base assembly 1. The air intake assembly 2 includes an air intake seat 201, with air inlets 202 at both ends of the bottom of the air intake seat 201. A return spring 203 is installed at the outer bottom end of the air intake seat 201. A water reservoir 204 is provided at the outer end of the air intake seat 201. An air passage 205 is provided inside the air intake seat 201. An air inlet pipe 206 is provided at the outer bottom end of the air intake seat 201. A first one-way air inlet valve 207 is installed in the middle section of the air inlet pipe 206. A motor 208 is housed inside the air intake seat 201, and an exhaust fan 209 is installed at the output end of the motor 208. The water reservoir 204... The outer end of the 4 is provided with a water inlet 210. The air supply component 3 is installed inside the air priming seat 201. The top outer end of the water storage seat 204 is connected to a water supply pipe 4, and a one-way water inlet valve 5 is installed inside the water supply pipe 4. The base component 1 includes a base 101. The top outer end of the base 101 is provided with a docking seat 102, and the two outer ends of the docking seat 102 are provided with air priming ports 103. The top outer end of the docking seat 102 is provided with a piston seat 104. The inner contour of the docking seat 102 matches the inner contour of the air priming seat 201. The air priming seat 201 is elastically connected to the docking seat 102 through a return spring 203. The outer contour of the piston seat 104 matches the inner contour of the water storage seat 204. The size of the air vent 205 is the same as that of the air priming port 103.

[0025] The operator starts the device and opens the water inlet 210 to store clean water into the water storage base 204. After closing the water inlet 210, the operator mates with the connector 10 and the breathing mask, then places the breathing mask on the patient. The device then operates normally. When the device is working, the motor 208 drives the exhaust fan 209 to rotate. During rotation, the exhaust fan 209 draws air from the air intake base 201 into the air storage bag 301 through the air inlet pipe 302. The cavity at the bottom of the air intake base 201 is connected to the cavity where the exhaust fan 209 is located through the air inlet pipe 206 and the ventilation slot 205. This allows the air in the cavity at the bottom of the air intake seat 201 to be drawn away by the exhaust fan 209. Because the cavity at the bottom of the air intake seat 201 is sealed, and a first one-way air inlet valve 207 is installed in the middle of the air inlet pipe 206, the air in the cavity at the bottom of the air intake seat 201 will be emptied under the continuous action of the suction force. Under the influence of atmospheric pressure, the air intake seat 201 will squeeze the return spring 203 and move downward along the docking seat 102 towards the base 101. During the downward movement of the air intake seat 201, the air intake port 103 and the air inlet port 202 will overlap, allowing outside air to enter the cavity at the bottom of the air intake seat 201. At this time, the air intake... When the cavity at the bottom of seat 201 returns to average atmospheric pressure, the air intake seat 201 can reset under the restoring force of the return spring 203. Since the exhaust fan 209 is located in the middle section inside the air intake seat 201, and the exhaust action of the exhaust fan 209 is on the cavity at the bottom of the air intake seat 201 rather than the outside, this effectively reduces the noise of the exhaust fan 209 during operation, thus improving the user's sleep quality. Furthermore, the water storage seat 204 surrounds the outside of the exhaust fan 209, further reducing its noise through its barrier. During the displacement of the air intake seat 201, the piston seat 104 will... The water base 204 is displaced, allowing the clean water stored in the water base 204 to enter the atomizing box 601 through the water supply pipe 4. The use of the one-way water inlet valve 5 can prevent the clean water in the water supply pipe 4 from being brought back to the water base 204 when the piston seat 104 is reset. Through the above design, the water supply volume of the water supply pipe 4 is positively correlated with the air extraction volume of the exhaust fan 209. This can effectively ensure that the amount of air drawn in by the device is consistent with the amount of water atomized. This can prevent the user from feeling uncomfortable due to excessively humid or dry air when inhaled, and can also prevent water droplets from condensing on the breathing mask due to excessively humid air, which can affect the user's sleep.

[0026] Please see Figures 1 to 7The air intake seat 201 is equipped with an atomizing component 6, and the atomizing component 6 is equipped with a mixing component 7. The air intake seat 201 is equipped with an air storage box 8 at the top outer end, and a return water pipe 9 is connected between the air storage box 8 and the atomizing component 6. The air storage box 8 is equipped with a connector 10 at the top outer end. The air supply component 3 includes an air storage bag 301. The bottom outer end of the air storage bag 301 is connected to an air inlet pipe 302, and a second one-way air inlet valve 303 is installed in the middle section of the air inlet pipe 302. The top outer end of the air storage bag 301 is connected to a ventilation pipe 304, and an electric control valve 305 is installed in the middle section of the ventilation pipe 304. The air inlet pipe 302 is connected to the interior of the air intake seat 201, and the air inlet pipe 302 is connected to the ventilation pipe 304 through the air storage bag 301. The atomizing assembly 6 includes an atomizing box 601, an atomizer 602 is installed at the bottom of the atomizing box 601, a partition plate 603 is installed inside the atomizing box 601, and a liquid return groove 604 is opened in the middle section of the partition plate 603. An atomizing tube 605 is connected between the atomizing box 601 and the air pipe 304. The water storage base 204 is connected to the atomizing box 601 through a water supply pipe 4. The atomizing box 601 is connected to the ventilation pipe 304 via the atomizing tube 605. The air storage box 8 is connected to the atomizing box 601 via the return water pipe 9, and the air storage box 8 is connected to the ventilation pipe 304. The mixing component 7 includes a rotating tube 701, a fan wheel 702 is installed in the middle section of the rotating tube 701, and a baffle fan 703 is connected to one end of the rotating tube 701. A spring box 704 is installed at the end of the rotating tube 701 away from the baffle fan 703, and a return fan 705 is connected to the outer end of the spring box 704.

[0027] The specific operation is as follows: After the exhaust fan 209 sends air into the air storage bag 301 through the air inlet pipe 302, the air can be stored inside the air storage bag 301. Thanks to the use of the second one-way air inlet valve 303, the air leakage inside the air storage bag 301 can be prevented. Through continuous air input, the air storage bag 301 can be kept in an expanded high-pressure state. The user's inhalation action is sensed by the breathing mask. The breathing mask can transmit the sensed inhalation action to the electric control valve 305 through an electrical signal. After receiving the electrical signal, the electric control valve 305 will open for one second. At this time, the air inside the air storage bag 301 will flow out through the ventilation pipe 304 due to the pressure difference. When the high-speed airflow flows in the ventilation pipe 304, it will drive the fan wheel 702 to rotate. When the fan 702 rotates, it drives the rotating tube 701 to rotate synchronously. After the water supply pipe 4 inputs clean water into the atomizing box 601, the clean water will come into contact with the atomizer 602 and atomize. The atomized water vapor will spread into the atomizing box 601. When the fan wheel 702 drives the rotating tube 701 to rotate, the rotating tube 701 will drive the baffle fan 703 to rotate. The baffle fan 703 is located directly below the atomizing tube 605. When the baffle fan 703 rotates, it can send the atomized water vapor through the atomizing tube 605 into the ventilation pipe 304 to mix with the air. Through the above operations, the equipment can achieve air humidification. Since the amount of atomized water vapor mixed with air is related to the number of rotations of the baffle fan 703, and the number of rotations of the baffle fan 703 is related to the number of rotations of the fan wheel 702, i.e., the number of air... The airflow regulation mechanism effectively ensures that the mixing volume of air and water vapor remains consistent, thus guaranteeing the comfort of the equipment. After mixing, the air and water vapor enter the air storage tank 8 for temporary storage. Due to the time difference between the mechanical air delivery speed and the user's inhalation speed, the air storage tank 8 allows for pre-preparation of the inhaled air, preventing situations where the user has no air to inhale. The inner cavity of the air storage tank 8 is designed with an incline. If there is too much water vapor during the temporary storage of the mixed gas in the air storage tank 8, the excess water vapor will liquefy and be stored at the bottom of the incline. When the fan wheel 702 drives the rotating tube 701 to rotate, it can also drive the spring box 704 to store potential energy. After the rotating tube 701 stops rotating, the spring box 702... 4. The stored potential energy will be released, driving the return fan 705 to rotate. The return fan 705 is located in a separate space within the atomizing box 601, separated by the partition plate 603. During the rotation of the return fan 705, a suction force is generated. This suction force enters the air storage box 8 through the return water pipe 9, drawing the liquefied water at the bottom of the air storage box 8 back into the atomizing box 601. Because the water is stored at the bottom of the inclined inner cavity of the air storage box 8, the suction force of the return fan 705 only acts on the water and does not draw the air back into the air storage box 8. The returned water can flow back into the atomizing box 601 for reuse through the return liquid groove 604 on the partition plate 603. Through this design, the stability of the equipment's air supply is ensured.It can also separate excess water vapor using the mixing component 7, further improving the user experience.

[0028] In summary, when using this respiratory therapy device with an airflow regulation mechanism, the operator first starts the device and opens the water inlet 210 to store clean water into the water storage base 204. After the operator closes the water inlet 210, the connector 10 is connected to the breathing mask, and the breathing mask is then placed in front of the patient, after which the device can work normally. When the device is in operation, the motor 208 drives the exhaust fan 209 to rotate. During rotation, the exhaust fan 209 draws air from the air intake seat 201 into the air storage bladder 301 through the air inlet pipe 302. The cavity at the bottom of the air intake seat 201 is connected to the cavity of the exhaust fan 209 through the air inlet pipe 206 and the ventilation slot 205. This allows the air in the cavity at the bottom of the air intake seat 201 to be drawn out by the exhaust fan 209. Because the cavity at the bottom of the air intake seat 201 is sealed, and a first one-way air inlet valve 207 is installed in the middle of the air inlet pipe 206, the air in the cavity at the bottom of the air intake seat 201 will be emptied under the continuous action of suction. Under the influence of atmospheric pressure, the air intake seat 201 will squeeze the return spring 203 and move along the docking... As the seat 102 moves downward toward the base 101, the air intake seat 201 moves downward, causing the air intake port 103 and the air inlet 202 to overlap. This allows outside air to enter the cavity at the bottom of the air intake seat 201. At this time, the cavity at the bottom of the air intake seat 201 returns to the average atmospheric pressure. Under the restoring force of the return spring 203, the air intake seat 201 can be reset. Since the exhaust fan 209 is located in the middle of the air intake seat 201, and the exhaust fan 209 draws air into the cavity at the bottom of the air intake seat 201 rather than the outside, this can effectively reduce the noise of the exhaust fan 209 during the operation of the equipment, which can effectively improve the sleep quality of the user. In addition, the water storage seat 204 surrounds the outside of the exhaust fan 209. Through the obstruction of the water storage seat 204, the noise of the exhaust fan 209 can be further reduced. Then, during the displacement of the air intake seat 201, the piston seat 104 will be displaced within the water storage seat 204. This allows the clean water stored in the water storage seat 204 to enter the atomizing box 601 through the water supply pipe 4. The use of the one-way water inlet valve 5 can prevent the clean water in the water supply pipe 4 from being brought back to the water storage seat 204 when the piston seat 104 is reset. Through the above design, the water supply volume of the water supply pipe 4 can be positively correlated with the air extraction volume of the exhaust fan 209. This can effectively ensure that the amount of air drawn by the device is consistent with the amount of water atomized. This can prevent the user from feeling uncomfortable due to excessively humid or dry air when inhaled into the user's body, and can also prevent water droplets from condensing on the breathing mask due to excessively humid air, which can affect the user's sleep. Then, after the exhaust fan 209 sends air into the air reservoir 301 through the air inlet pipe 302, the air can be stored inside the air reservoir 301. Thanks to the use of the second one-way air inlet valve 303, the air leakage inside the air reservoir 301 can be prevented. Through continuous air input, the air reservoir 301 can be kept in an inflated high-pressure state. The user's inhalation action is sensed by the breathing mask, which can transmit the sensed inhalation action to the electric control valve 305 through an electrical signal. After receiving the electrical signal, the electric control valve 305 will open for one second. At this time, the air inside the air reservoir 301 will flow out through the ventilation pipe 304 due to the pressure difference. When the high-speed airflow flows in the ventilation pipe 304, it will drive the fan wheel 702 to rotate. When the fan wheel 702 rotates, it will drive the rotating pipe 701 to rotate synchronously. The water supply pipe 4 inputs clean water to After entering the atomizing box 601, clean water comes into contact with the atomizer 602 and is atomized. The atomized water vapor spreads into the atomizing box 601. When the fan wheel 702 drives the rotating tube 701 to rotate, the rotating tube 701 drives the baffle fan 703 to rotate. The baffle fan 703 is located directly below the atomizing tube 605. When the baffle fan 703 rotates, it can send the atomized water vapor through the atomizing tube 605 into the ventilation tube 304 to mix with the air. Through the above operations, the equipment can achieve air humidification. Since the amount of atomized water vapor mixed with air is related to the number of rotations of the baffle fan 703, and the number of rotations of the baffle fan 703 is related to the number of rotations of the fan wheel 702, i.e., the airflow, this airflow adjustment mechanism can effectively ensure that the amount of air and water vapor mixed is always consistent, which can effectively ensure the comfort of using the equipment. Finally, the air and water vapor mix and enter the air storage tank 8 for temporary storage. Because there is a time difference between the mechanical air delivery speed and the user's inhalation speed, the air storage tank 8 allows for pre-preparation of the inhaled air, preventing situations where the user has no air to inhale. The air storage tank 8 has an inclined inner cavity design; if there is excessive water vapor during the temporary storage of the mixed gas, the excess water vapor will liquefy and be stored at the bottom of the inclined structure. When the fan wheel 702 drives the rotating tube 701 to rotate, it also drives the spring box 704 to store potential energy. After the rotating tube 701 stops rotating, the potential energy stored in the spring box 704 is released, driving the return fan 705 to rotate. The return fan 705 is located in the atomizing box 6. Within the separate space separated by the partition plate 603, the rotation of the return fan 705 generates a suction force. This suction force enters the air storage tank 8 through the return water pipe 9, drawing the liquefied water at the bottom of the air storage tank 8 back into the atomizing box 601. Since the water is stored at the bottom of the inclined inner cavity of the air storage tank 8, the suction force of the return fan 705 only acts on the water and does not draw the air back into the air storage tank 8. The returned water can flow back into the atomizing box 601 for reuse through the return liquid groove 604 on the partition plate 603. Through the above design, while ensuring the stability of the equipment's air supply, the mixing component 7 can also separate excess water vapor, which further improves the comfort of using the equipment.
