[0022] In the related art, after the atomization device is turned on, it will continue to atomize without considering the user's breathing conditions, which not only wastes the medicine liquid but also produces more free medicine mist, causing unnecessary medicine liquid cleaning problems.

[0023] In order to solve the above problems, an embodiment of the present application provides a method for controlling a nebulizer device for respiratory medicine. The method is applied to a respiratory nebulizer. First, the main switch of the respiratory nebulizer is turned on, and the air pressure sensor starts to detect the air pressure value. This step detects the pressure generated when the user breathes through the air pressure sensor, which can take into account the user's breathing situation and is conducive to improving the user's use experience. Secondly, when the pressure value measured by the air pressure sensor is less than the first pressure threshold, the control unit is in the first atomization state. When the pressure value measured by the air pressure sensor is greater than or equal to the first pressure threshold, the control unit is in the second atomization state. The first atomization state in this step is the state of the control unit when the user inhales, and the gas transmission part participates in the atomization process at this time. The second atomization state is the state of the control unit when the user exhales or holds his breath, and the gas transmission part does not participate in the atomization process at this time. The problem of wasting liquid medicine and cleaning liquid medicine can be solved, which is conducive to improving the user's use experience. Subsequently, the breathing intensity information input by the user is detected. This step allows the user to set a personalized setting that suits him / herself, which can improve the user's use experience. Finally, the first pressure threshold is adjusted according to the breathing intensity information. This step adjusts the first pressure threshold according to the breathing intensity information input by the user, personalizes the respiratory nebulizer, and improves the user's use experience.

[0024] The control method for the respiratory nebulizer device provided in the embodiment of the present application can be applied to the respiratory nebulizer device. In this case, the respiratory nebulizer device is the executor of the control method for the respiratory nebulizer device provided in the embodiment of the present application. The embodiment of the present application does not impose any restrictions on the specific type of the respiratory nebulizer device.

[0025] In order to better understand the nebulizer device for respiratory medicine provided in the embodiment of the present application, a diagram of the nebulizer device for respiratory medicine provided in the embodiment of the present application is introduced below.

[0026] Please also read Figure 1 and Figure 2 The embodiment of the present application provides a respiratory atomization device 10, including a mask 12, a liquid storage container 11, an air pressure sensor 13, a liquid atomization unit 14, an air delivery pipeline 15, an air delivery unit 24, a control unit 16, a housing 21, a breathing intensity knob 22 and an indicator light 23, wherein: The mask 12 is disposed on the housing 21 and has an air outlet 121 and a first interface 122 . The air outlet 121 is used to discharge the gas exhaled by the user, and the first interface 122 is used to connect to the outlet 112 of the atomized liquid.

[0027] The liquid storage container 11 is arranged at the first interface 122 and is located in the shell 21. The top of the liquid storage container 11 has a switchable lid 111 for adding liquid medicine. One side of the liquid storage container 11 has a liquid level line for indicating the maximum amount of liquid medicine added. The other side of the liquid storage container 11 has an outlet 112 for atomized liquid medicine. The outlet 112 for atomized liquid medicine is connected to the first interface 122. The outlet 112 for atomized liquid medicine is higher than the liquid level line. The bottom of the liquid storage container 11 has a second interface 113 for transmitting airflow to the liquid storage container 11.

[0028] The air pressure sensor 13 is disposed inside the liquid storage container 11 and above the liquid level, and is used to detect the pressure generated when the user exhales and inhales.

[0029] The liquid atomizing unit 14 is disposed on the second interface 113 and has a liquid suction pipe 141 for atomizing the liquid medicine in the liquid storage container 11 .

[0030] Gas delivery pipeline 15 One end of the gas delivery pipeline 15 is connected to the second interface 113 for transmitting airflow.

[0031] The gas delivery portion 24 is disposed at the other end of the gas delivery pipeline 15 , and is used to drive the gas flow from the gas delivery pipeline 15 to the liquid storage container 11 .

[0032] The control unit 16 is disposed in the housing 21 , and is in communication connection with the air pressure sensor 13 , the liquid atomization unit 14 , and the gas delivery unit 24 , and is used to control the air pressure sensor 13 , the liquid atomization unit 14 , and the gas delivery unit 24 .

[0033] The breathing intensity knob 22 is disposed on the housing 21 and is in communication with the control unit 16 so as to allow the user to make personalized adjustments according to his / her own breathing intensity.

[0034] The indicator light 23 is disposed on the housing 21 and is in communication with the control unit 16 , and is used to indicate the user's adjustment of the breathing intensity knob 22 .

[0035] The liquid storage container 11 has a switchable lid 111 and an outlet 112 for atomized liquid. The switchable lid 111 can be opened and closed and fits tightly with the liquid storage container 11. When opened, it is used to add liquid medicine. When closed, it is used to maintain the air tightness of the liquid storage container 11 and prevent the liquid medicine from being contaminated by the outside. The mask 12 can fit tightly with the user's face. The air pressure sensor 13 is used to detect the air pressure in the liquid storage container 11. When the user exhales and inhales, a pressure change occurs in the liquid storage container 11. The liquid atomization unit 14 has a liquid suction pipe 141. The liquid atomization unit 14 can suck liquid through the liquid suction pipe 141. The liquid medicine in the liquid storage container 11 is taken and atomized. The airflow generated by the air delivery part 24 is transmitted to the bottom of the liquid atomization part 14 through the air delivery pipe 15. The airflow can blow the atomized liquid medicine from the outlet 112 of the atomized liquid medicine to the mask 12. The shell 21 includes a switchable cover 111, a breathing intensity knob 22, an indicator light 23 and a mask 12. The breathing intensity knob 22 is used to allow the user to make personalized adjustments according to his or her own breathing intensity. The indicator light 23 is used to indicate the user's adjustment of the breathing intensity knob 22. The user can observe the indicator light 23 to more conveniently adjust the breathing intensity knob 22.

[0036] It is understandable that the mask 12 can be a plastic mask. The liquid storage container 11 can be a bottled container made of plastic or other materials that will not be corroded by the liquid medicine, such as a polyethylene container. The air pressure sensor 13 can be various air pressure sensors, such as a capacitive air pressure sensor. The liquid atomization unit 14 can be a piezoelectric crystal or a passive mechanical structure of a jet atomization type. The piezoelectric crystal atomizes the liquid medicine by high-frequency vibration, and the passive mechanical structure of the jet atomization type atomizes the liquid medicine by airflow as power, such as a jet nebulizer. The gas delivery unit 24 can be an air pump or a fan. The gas delivery pipeline 15 can be a plastic pipeline. The control unit 16 can be a single-chip microcomputer. The breathing intensity knob 22 can be various knob switches. The indicator light 23 can be various lights, such as an LED light.

[0037] As can be seen from the above, the respiratory nebulizer device 10 provided in the embodiment of the present application has an air pressure sensor 13 that can detect the air pressure value inside the liquid storage container 11. When the user wears the mask 12 and inhales, a negative pressure will be generated inside the liquid storage container 11, which is then detected by the air pressure sensor 13. The control unit 16 controls the gas transmission unit 24 to generate an airflow, and the airflow passes through the gas transmission pipeline 15 to reach the liquid atomization unit 14. The atomized substance generated by the liquid atomization unit 14 is carried by the airflow and flows out from the outlet 112 of the atomized liquid, reaches the mouth of the user wearing the mask 12, and then enters the user's body to complete the atomization treatment. ; When the user exhales or holds his breath, negative pressure cannot be generated inside the liquid storage container 11, so the control unit 16 controls the gas delivery unit 24 to shut down, and there will be no airflow to carry the atomized substance, so as to achieve the purpose of saving the medicine liquid, and also solve the problem of residual medicine liquid in the external environment. A shell 21 is also provided to protect the liquid storage container 11 and its internal structure and the control unit 16. A breathing intensity knob 22 is also provided to allow the user to make personalized adjustments according to his or her own breathing intensity to improve the user's usage experience. An indicator light 23 is also provided to prompt the user whether the gas delivery unit 24 is working, so as to facilitate the user to adjust the breathing intensity knob 22.

[0038] With such a configuration, the respiratory nebulizer provided in the present application detects the user's breathing pressure through the air pressure sensor 13 and performs different nebulizer modes at different breathing periods of the user, which can solve the problem that the existing nebulizer always produces mist, resulting in waste of liquid medicine and cleaning of liquid medicine.

[0039] In some embodiments, see Figure 3 and Figure 4 , the mask 12 includes a first one-way valve 41 and a second one-way valve 42, wherein: The first one-way valve 41 is disposed at the first interface 122 , and is used to allow the atomized substance or gas to enter the mask 12 only from the liquid storage container 11 . The switching pressure of the first one-way valve 41 is lower than the minimum inhalation pressure of the human body.

[0040] The second one-way valve 42 is disposed at the air outlet 121 on the mask 12, and is used to allow the atomized substance or gas to enter the outside of the mask 12 only from the inside of the mask 12. The switching pressure of the second one-way valve 42 is less than the minimum exhalation pressure of the human body.

[0041] The structures of the first one-way valve 41 and the second one-way valve 42 are as shown in the one-way valve 30, and the one-way valve 30 has an elastic film 31 and a limit rod 32. The first one-way valve 41 is arranged at the first interface 122 of the mask 12, and the air outlet direction of the first one-way valve 41 is the inside of the mask 12. The second one-way valve 42 is arranged at the air outlet hole 121 of the mask 12, and the air outlet direction of the second one-way valve 42 is the outside of the mask 12.

[0042] It can be understood that the elastic film 31 can be made of elastic gel, and the limit rod 32 can be made of plastic or other rigid materials, such as a pull rod. The elastic film 31 can be closed and opened, and can be tightly closed to isolate the air when closed. The switching pressure of the first one-way valve 41 is less than the minimum inhalation pressure of the human body, and the switching pressure of the second one-way valve 42 is less than the minimum exhalation pressure of the human body.

[0043] With such arrangement, when the user inhales, external air cannot enter the mask 12 from the air outlet 121, while the air in the liquid storage container 11 is sucked away, making it easier for the air pressure sensor 13 to detect the negative pressure generated when the user inhales. When the user exhales, air will not enter the liquid storage container 11 and cause the air pressure in the liquid storage container 11 to be too high, thereby avoiding large errors when detecting the next inhalation of the user, and can effectively improve the accuracy and stability of the air pressure value measured by the air pressure sensor 13.

[0044] In some embodiments, see Figure 5 The liquid atomization unit 14 is a passive mechanical structure of a jet atomization type, the jet liquid atomization unit 51, the jet liquid atomization unit 51 can generate an atomization effect by means of airflow, and the liquid storage container 11 also includes a second pipeline 52, a first air pump 53, and a first switch 54, wherein: One end of the second pipe 52 is connected to the gas delivery pipe 15 , and the other end of the second pipe 52 is connected to the liquid storage container 11 and is located above the liquid level of the liquid storage container 11 .

[0045] The first air pump 53 is disposed in the second pipeline 52 , and is used for transporting the gas in the liquid storage container 11 to the liquid atomization unit 14 . The first air pump 53 is in communication connection with the control unit 16 .

[0046] The first switch 54 is disposed at the connection between the second pipeline 52 and the gas pipeline 15 , and is used to select opening the gas pipeline 15 or the second pipeline 52 . The first switch 54 is in communication connection with the control unit 16 .

[0047] Among them, one end of the second pipeline 52 is connected to the gas pipeline 15, and the other end is connected to the liquid level of the liquid storage container 11. The first air pump 53 is located in the second pipeline 52, and the gas transmission direction of the first air pump 53 is from top to bottom. The first switch 54 is located at the intersection of the second pipeline 52 and the gas pipeline 15, and is used to select to open one of the second pipeline 52 and the gas pipeline 15. When the first switch 54 chooses to open the second pipeline 52, the airflow can flow from the liquid level of the liquid storage container 11 through the second pipeline 52 to the jet liquid atomization part 51; when the first switch 54 chooses to open the gas pipeline 15, the airflow flows from the gas delivery part 24 through the gas pipeline 15 to the jet liquid atomization part 51.

[0048] It is understood that the jet liquid atomizing unit 51 can be a venturi nozzle, and the negative pressure generated by the venturi nozzle draws the liquid medicine from the liquid suction pipe 141, and then the liquid medicine is ejected from the nozzle. The second pipe 52 can be made of plastic or other materials that will not be corroded by the liquid medicine. The first air pump 53 can be a small electric fan. The first switch 54 can be an electromagnetic valve, which is used to select and open one of the second pipe 52 and the gas pipeline 15.

[0049] With such arrangement, when the user exhales or holds his breath, the first air pump 53 can be started, and the first switch 54 can select to open the second pipe 52. At this time, the atomized substance and gas cannot flow out of the liquid storage container 11, and the first air pump 53 can provide airflow, which circulates in the liquid storage container 11 to atomize the medicine, ensuring that there is enough atomized substance in the liquid storage container 11 when the user inhales next time, thereby saving the medicine and ensuring the effect of atomization therapy.

[0050] In some embodiments, see Figure 1 The liquid atomization unit 14 is an active piezoelectric crystal piece. When the liquid aspiration pipe 141 draws the medicine into the active piezoelectric crystal piece, the active piezoelectric crystal piece atomizes the medicine by vibration.

[0051] It can be understood that the liquid atomization part 14 can be a piezoelectric ceramic.

[0052] With such arrangement, when the user exhales or holds his breath, the gas delivery unit 24 is not started, and the atomized liquid medicine produced by the liquid atomization unit 14 cannot flow out of the liquid storage container 11 with the airflow, thereby ensuring that there is enough atomized material in the liquid storage container 11 when the user inhales next time, thereby saving liquid medicine and ensuring the effect of atomization therapy.

[0053] In order to better understand the control method of the nebulizer device for respiratory medicine provided in the embodiment of the present application, the specific implementation process of the control method of the nebulizer device for respiratory medicine provided in the embodiment of the present application is exemplarily introduced below.

[0054] Figure 6 A schematic flow chart of a control method for a respiratory nebulizer provided in an embodiment of the present application is shown. The control method for a respiratory nebulizer includes: S100, start the respiratory nebulizer device, and the air pressure sensor starts to detect the air pressure value.

[0055] It can be understood that after the respiratory nebulizer device is started, the air pressure sensor starts to detect the air pressure in the liquid storage container, and the control unit receives the air pressure value measured by the air pressure sensor.

[0056] Such a setting can quickly respond to the user's breathing movements to enhance the user experience.

[0057] S200, when the pressure value measured by the air pressure sensor is less than the first pressure threshold, the control unit is in the first atomization state, and when the pressure value measured by the air pressure sensor is greater than or equal to the first pressure threshold, the control unit is in the second atomization state. The first atomization state refers to the state in which the gas delivery part participates in the atomization process, and the second atomization state refers to the state in which the gas delivery part does not participate in the atomization process.

[0058] It can be understood that the first pressure threshold is used to distinguish the breathing pressure of the user, and the default value of the first pressure threshold can be a standard atmospheric pressure, or a pressure value slightly less than the standard atmospheric pressure, but is not limited thereto. The atomization state of the control unit is used to execute different atomization schemes, and different atomization schemes are used to respond to the user's exhalation, breath holding and inhalation actions.

[0059] With such a configuration, different atomization schemes can be executed under different breathing conditions of the user to solve the problem of liquid medicine waste.

[0060] Optionally, the control method of the respiratory nebulizer device is applied to a respiratory nebulizer device whose nebulization mode is jet nebulization, and the liquid nebulizer part is a passive mechanical structure, such as Figure 5 The jet liquid atomization unit 51 shown in the figure comprises: S210, when the control unit is in the first atomization state, the control unit controls the first switch to select to open the gas pipeline, and the control unit controls the gas delivery part to open.

[0061] It can be understood that when the control unit is in the first atomization state, it means that the user is in the inhalation state. At this time, the control unit controls the first switch to select to open the gas pipeline and control to open the gas delivery part. The airflow passes through the gas pipeline 15 from the gas delivery part 24 to the jet liquid atomization part 51. The jet liquid atomization part 51 uses the airflow as the power to absorb and atomize the medicine liquid, and the airflow drives the atomized medicine liquid to flow out from the atomized medicine liquid outlet 112 and enter the user's body.

[0062] Such a configuration shows the atomization method of the respiratory atomization device when the user inhales and the atomization method is jet atomization.

[0063] S220, when the control unit is in the second atomization state, the control unit controls the first switch to select and open the second pipeline, and the control unit controls the first air pump to start, wherein the first air pump and the air delivery unit are not started at the same time.

[0064] It can be understood that when the control unit is in the second atomization state, it means that the user is in the exhalation or breath-holding state. At this time, the control unit controls the first switch to select to open the second pipeline and control to open the first air pump. The first air pump generates an airflow, and the airflow passes through the second pipeline 52 from above the liquid surface of the liquid storage container 11 to reach the jet liquid atomization part 51. The jet liquid atomization part 51 uses the airflow as the power to absorb and atomize the medicine liquid. The atomized medicine liquid accumulates above the liquid surface of the liquid storage container 11 to wait for the user's next inhalation action.

[0065] Such a setting shows that when the user exhales or holds his breath, and the atomization method of the respiratory nebulizer device is jet atomization, it can ensure that the user has enough atomized liquid medicine when the user inhales next time.

[0066] Optionally, the control method of the respiratory nebulizer device is applied to a respiratory nebulizer device with ultrasonic nebulization as the nebulization mode, and the liquid nebulization part is an active piezoelectric crystal piece, including: S230, when the control unit is in the first atomization state, the control unit controls the liquid atomization part to open, and the control unit controls the gas delivery part to open.

[0067] It can be understood that when the control unit is in the first atomization state, it means that the user is in the inhalation state. At this time, the control unit controls the liquid atomization part to open and the gas supply part to open. The airflow passes from the gas supply part through the gas supply pipeline to the liquid atomization part, and the medicine atomized by the liquid atomization part flows into the user's body along with the airflow.

[0068] Such a configuration shows the atomization method of the atomization device for respiratory medicine when the user inhales and the atomization method is ultrasonic atomization.

[0069] S240, when the control unit is in the second atomization state, the control unit controls the liquid atomization part to open, and the control unit controls the gas delivery part to close.

[0070] It can be understood that when the control unit is in the second atomization state, it means that the user is in the exhalation or breath-holding state. At this time, the control unit controls the liquid atomization part to open and the gas delivery part to close. No airflow is generated inside the device, and the liquid atomized by the liquid atomization part accumulates above the liquid surface of the liquid storage container.

[0071] Such a setting shows that when the user exhales or holds his breath, and the atomization method of the respiratory nebulizer device is ultrasonic atomization, it can ensure that the user has enough atomized liquid medicine when the user inhales next time.

[0072] S300, detecting the breathing intensity information input by the user, and adjusting the first pressure threshold according to the breathing intensity information, wherein the breathing intensity information is used to reflect the intensity of the user's exhalation pressure and inhalation pressure.

[0073] It can be understood that the breathing pressure of each user is different due to factors such as the user's physical condition and age. The breathing intensity information can be represented by the breathing intensity (the breathing intensity is a scalar that represents the size of the user's breathing intensity). Therefore, it is necessary to set different breathing intensities according to different users, and then set different first pressure thresholds according to different breathing intensities. The breathing intensity is input by the user himself, and the input method can be input through the breathing intensity knob 22, or through a mobile phone or computer after wirelessly connecting to the control unit.

[0074] Such a setting can make the respiratory nebulizer device more personalized and more suitable for the user's physical condition.

[0075] In a possible implementation, in step S300, detecting the breathing intensity information input by the user includes: S310, obtaining breathing intensity information input by the user from the breathing intensity knob.

[0076] It can be understood that the control unit can obtain the knob amount input by the user from the breathing intensity knob, and then obtain the breathing intensity converted in proportion according to the knob amount of the breathing intensity knob.

[0077] S320, when the breathing intensity information indicates that the breathing intensity set by the user is a minimum value, adjust the first pressure threshold to be equal to one standard atmospheric pressure; when the breathing intensity information indicates that the breathing intensity set by the user is greater than the minimum value, adjust the first pressure threshold to be less than one standard atmospheric pressure.

[0078] It can be understood that when the breathing intensity set by the user is the minimum value, it means that the negative pressure generated when the user inhales is very small (the smaller the negative pressure, the closer to the standard atmospheric pressure), so the first pressure threshold is adjusted to be equal to one standard atmospheric pressure; when the breathing intensity set by the user is greater than the minimum value, it means that the negative pressure generated when the user inhales is greater, so the first pressure threshold is adjusted to be less than one standard atmospheric pressure. The minimum value of the first pressure threshold can be the air pressure value measured by the air pressure sensor when a healthy young and middle-aged person inhales, or it can be other air pressure values.

[0079] Such an arrangement is conducive to more detailed personalization of the nebulizer device for respiratory medicine.

[0080] Optionally, in step S300, the respiratory nebulizer control method further includes: S330, the indicator light is on when the pressure value measured by the air pressure sensor is less than the first pressure threshold, wherein the indicator light is used to instruct the user to adjust the breathing intensity information.

[0081] It is understandable that when a user uses the atomization state of the atomization device for respiratory medicine, it is difficult to observe the atomization state of the atomization device for respiratory medicine, so an indicator light is provided to indicate the atomization state of the atomization device for respiratory medicine, so as to instruct the user to adjust the breathing intensity information.

[0082] Such a setting is helpful for users to adjust their breathing intensity information and improves their usage experience.
