In addition, the term "or" used in this article may include any one or more combinations of the associated listed items depending on the actual situation.

[0027] Figure 1 FIG. 1 is a simplified schematic diagram of a breathing simulation system according to an embodiment of the present invention. Figure 1 As shown, the embodiment of the present invention provides a breathing simulation system 1 for testing a plurality of atomizing devices 2 to be tested. The breathing simulation system 1 comprises a main body 10 , a plurality of connecting pipes 12 , an air extraction mechanism 14 , a liquid supply mechanism 16 and an aerosol condensation module 18 .

[0028] The main body 10 is formed with a main air flow channel P1. The main body 10 may be, for example, a cylindrical tube arranged along the gravity direction Dg. A plurality of air inlet holes 102 and at least one liquid outlet (e.g., a liquid discharge hole 104) are arranged on the tube wall of the main body 10. The plurality of air inlet holes 102 may be arranged around the central axis of the main body 10, and the plurality of connecting pipes 12 are respectively connected to the corresponding plurality of air inlet holes 102. In some embodiments, the main body 10 has an upper end 101 and a lower end 103. The main body is connected to the lower plate 105 at the lower end 103, and the liquid discharge hole 104 is arranged and passes through the lower plate 105.

[0029] The following first describes the atomization device 2 to be tested according to an embodiment of the present invention by way of example. Figure 2 and Figure 3 , Figure 2 is a schematic diagram of an atomization device to be tested according to an embodiment of the present invention, Figure 3 Schematic diagram of the drug placement module of the atomization device to be tested. Figure 2 and Figure 3 As shown, the atomization device 2 to be tested may include, for example, a medicine placement module 20 and an atomization module 21. The medicine placement module 20 includes a medicine placement housing 200, and has a liquid containing tank 202 formed in the medicine placement housing 200 and a through hole 204 connected to the liquid containing tank 202. In addition, the medicine placement module 20 also includes a movable cover 206 movably disposed on the medicine placement housing 200.

[0030] It should be noted that if Figure 2As shown, the atomization device 2 to be tested may include a main body housing 24, an atomization kit 25 disposed on the main body housing 24, and a processor disposed in the main body housing 24. Thus, a power source can be provided to the atomization module 21, and the atomization module 21 can be used to atomize the liquid contained in the liquid tank 202.

[0031] In addition, the atomizer kit 25 includes an atomizer kit housing 250 disposed between the medicine placement module 20 and the main body housing 24 and an air inlet 252 extending from the atomizer kit housing 250, and a portion (e.g., the upper half) of the air inlet 252 is used for the user to inhale the atomized gas after the atomizer module 21 atomizes the liquid in the liquid storage tank 202, and the other portion (e.g., the lower half) is used to allow the first sensor 23 disposed in the main body housing 24 to sense the pressure generated when the user inhales the atomized gas. In this way, the atomizer module 21 can be driven to atomize the liquid contained in the liquid storage tank 202 when the first sensor 23 senses the generation of negative pressure, so as to generate atomized gas for the user to inhale. For example, the first sensor 23 can be, for example, a pressure sensor, and the first sensor 23 can be disposed in a housing space in the atomizer kit 25 that is connected to the lower half of the air inlet 252.

[0032] However, the above example is only one feasible embodiment of the atomization device 2 to be tested, and the present invention is not limited thereto. The atomization device 2 to be tested may only include the basic structure of the atomization module 21 and a shell having a liquid containing tank 202 and an air inlet 252 .

[0033] Please refer to Figure 1 , multiple atomization devices 2 to be tested may correspond to multiple connecting pipes 12 arranged around the main body 10, so that the connecting pipes 12 are located between the corresponding air inlet holes 102 and the corresponding air inlet 252 of the atomization device 2 to be tested. In some embodiments, an airtight member 120 is further provided at the connection between each connecting pipe 12 and the corresponding air inlet 252 for sealing the connection. The airtight member 120 may be made of an elastic material such as rubber, whereby the connecting pipe 12 and the corresponding air inlet 252 may be connected in an airtight manner, so that the negative pressure formed in the main body 10 may further extend to the inside of the atomization device 2 to be tested through the air inlet 252.

[0034] On the other hand, Figure 1As shown, the air extraction mechanism 14 is connected to the main air flow channel P1, and is used to extract air from the upper end 101 to generate negative pressure in the main air flow channel P1, and form an air flow path Pa between the air extraction mechanism 14 and each air inlet 252. In some embodiments, the air extraction mechanism 14 includes an air extraction pump 140 and an air extraction controller 142. The air extraction pump 140 can be, for example, an axial flow blower or an axial flow blower, and the air extraction pump 140 is arranged at one end of the main body 10. The air extraction controller 142 can be, for example, a microprocessor or a microcontroller, and the air extraction controller 142 is electrically connected to the air extraction pump 140, and is configured to control the air extraction pump 140 to open and close in a predetermined mode, so that the negative pressure changes in the main air flow channel P1 according to the predetermined mode. However, the present invention is not limited to this. The air extraction mechanism 14 can also be equipped with a solenoid valve by the air extraction pump 140, and the switch of the solenoid valve is controlled by the air extraction controller 142 in a predetermined mode, and the mechanism of air suction simulation can also be achieved.

[0035] In a preferred embodiment, the air pump 140 can preferably provide a negative pressure greater than 10 Pa to the main body 10, and provide a flow rate of 100 liters / minute. In some embodiments, the breathing simulation system 1 also includes a barometer 17, which is arranged in the main air flow channel P1, for detecting the pressure in the main air flow channel P1. Optionally, the barometer 17 can be electrically connected to the air extraction controller 142. Therefore, when the air extraction controller 142 determines that the pressure of the main air flow channel P1 deviates from the predetermined pressure value based on the pressure detected by the barometer 17, the negative pressure generated in the main air flow channel P1 can be adaptively adjusted to maintain the main air flow channel P1 at a predetermined pressure value.

[0036] At Figure 1 In the embodiment, the liquid supply mechanism 16 includes a plurality of liquid supply containers 160 and a plurality of liquid supply tubes 162. The plurality of liquid supply containers 160 are each used to contain the test liquid L, and are connected to the corresponding plurality of atomization devices 2 to be tested through the plurality of liquid supply tubes 162. For example, the liquid supply container 160 may be a hard tube body made of a transparent material, the liquid supply container 160 is connected to the liquid supply tube 162, and the liquid supply tube 162 may pass through the movable cover 206 of the atomization device 2 to be tested to extend into the liquid containing tank 202. In this way, the liquid supply container 160 can be connected to the liquid containing tank 202 of the corresponding atomization device 2 to be tested through the liquid supply tube 162, so that the test liquid L in the liquid supply container 160 can be provided to the corresponding liquid containing tank 202 through the liquid supply tube 162.

[0037] Therefore, under the above-mentioned architecture, a test procedure can be executed on the atomization device 2 to be tested.

[0038] Please refer to Figure 4 , Figure 4 FIG. 1 is a flow chart of a test procedure according to an embodiment of the present invention. Figure 4 As shown, the test procedure may include the following steps:

[0039] Step S40: configuring the air extraction mechanism to apply negative pressure to each air inlet through each air flow path in a predetermined mode;

[0040] Step S41: configuring each atomization device to be tested to atomize the test liquid in the liquid storage tank when a sensor detects negative pressure at the air inlet, so as to generate aerosol that flows into the main air flow channel; and

[0041] Step S42: configuring the liquid supply mechanism to supply the corresponding test liquid to the corresponding liquid tank according to the consumption of the liquid tank.

[0042] In detail, the air extraction controller 142 can be configured to control the air extraction pump 140 to apply negative pressure to each air inlet 252 through the air flow path Pa in a predetermined mode. The predetermined mode can simulate the frequency of human breathing, such as inhaling for two seconds and then stopping for two seconds, and continuously cycling. It should be noted that although only the inhalation behavior is simulated in the above test procedure, the present invention is not limited to this. For example, in other embodiments, an inflation mechanism including an inflation pump can also be configured, and a positive pressure can be applied to the main body 10 through the controller to simulate the possible exhalation behavior of the user when using the atomization device 2 to be tested.

[0043] As the test liquid in the liquid tank 202 decreases, the test liquid L in the liquid supply container 160 can be added to the liquid tank 202 of the atomizing device 2 to be tested in a quantitative manner, so that the test liquid in the liquid tank 202 is maintained at a certain height, and a mechanism for automatically replenishing the liquid can be realized. In one embodiment, the aforementioned mechanism for automatically replenishing the liquid can be achieved by setting a peristaltic pump on the liquid supply tube 162, or by a common drip flow regulator, and is not limited thereto. In this way, the mechanism adopted by the present invention can achieve the effect of automatic quantitative drug delivery without complicated design.

[0044] Please refer to Figure 1 The aerosol condensation module 18 may be disposed in the main body 10, and is used to condense at least a portion of the aerosol generated when the atomizing device 2 to be tested performs the aforementioned test procedure into waste liquid, and discharge it through the drain hole 104. In some embodiments, the aerosol condensation module 18 includes one or more baffles 180 disposed near the upper end 101. When negative pressure is generated, since the atomized gas generated by the atomizing device 2 to be tested will travel along the airflow path Pa and the main airflow channel P1, and flow out toward the upper end 101, one or more baffles 180 may be disposed on this airflow path to block at least a portion of the aerosol from condensing on the baffle 180 to form waste liquid 3 by hindering the flow of the aerosol. When the waste liquid 3 flows downward due to gravity, it can be discharged from the drain hole 104 located below. In some embodiments, a drain pipe 1040 may be further disposed to guide the waste liquid 3 to a waste liquid container for collection / storage.

[0045] For further reference Figure 5 , Figure 5 FIG. 1 is a schematic diagram of the detailed architecture of the breathing simulation system according to an embodiment of the present invention. Figure 5 As shown, by arranging a plurality of atomizing devices 2 to be tested around the main body 10, the breathing simulation system 1 provided by the present invention can test a large number of atomizing devices 2 to be tested at the same time, and can also automatically replenish the medicine liquid and collect the medicine mist. When a large number of atomizing devices 2 to be tested are tested at the same time, the breathing simulation system 1 of the present invention can provide the same test conditions for each atomizing device 2 to be tested, so that the test conditions (such as the suction volume or the negative pressure value) of each inhalation port 252 are consistent. In addition, the atomizing device 2 to be tested is easy to disassemble and fix to the breathing simulation system 1, and the breathing simulation system 1 can stably drive a plurality of atomizing devices 2 to be tested to spray. In the present embodiment, the breathing simulation system 1 may include a bearing seat 15, and a plurality of positioning mechanisms 19 for carrying the atomizing device 2 to be tested. The plurality of positioning mechanisms 19 are arranged on the peripheral side of the main body 10, for example, they can be arranged around the main body 10 with the main body 10 as the axis to make more efficient use of space.

[0046] In detail, the positioning mechanism 19 can be, for example, a column, and the positioning mechanism 19 has an upper surface 190, a side surface 191, and a lower surface 192. The lower surface 192 is substantially parallel to the ground and contacts the support base 15, and the upper surface 190 is an inclined surface inclined at a predetermined angle relative to the ground. The upper surface 190 is used to support the corresponding atomization device 2 to be tested. When the atomization device 2 to be tested is set on the inclined upper surface 190, the corresponding liquid containing tank 202 will be inclined at a predetermined angle relative to the ground.

[0047] Corresponding to the above configuration, such as Figure 1 As shown, the connecting pipe 12 is also inclined at a predetermined angle relative to the ground. In a preferred embodiment, the predetermined angle may be, for example, in the range of 10 to 30 degrees, preferably 15 degrees. Therefore, when the connecting pipe 12 is also inclined at a predetermined angle relative to the ground, the condensed waste liquid formed when the medicine mist contacts the air inlet 252 and the pipe wall of the connecting pipe 12 will flow into the main body 10 under the action of gravity, thereby preventing the waste liquid from staying in the air inlet 252 and the connecting pipe 12, and providing an automated waste liquid removal mechanism for the air inlet 252 and the connecting pipe 12.

[0048] On the other hand, since the aerosol condensation module 18 may not be able to completely condense all the aerosols generated by the atomization device 2 to be tested, Figure 5 As shown, the breathing simulation system 1 may further include an aerosol collection pipe 13 disposed on the exhaust side of the suction pump 140 , and the aerosol collection pipe 13 may be connected to another waste liquid receiving device to collect waste liquid.

[0049] Please refer to Figure 1In some embodiments, the breathing simulation system 1 further includes a breathing characteristic simulator 11, and the breathing characteristic simulator 11 is electrically connected to the air extraction mechanism 14 (for example, connected to the air extraction controller 142). The breathing characteristic simulator 11 is used to simulate one or more of a plurality of breathing characteristics to generate a corresponding negative pressure. For example, the breathing characteristics may include breathing sounds, breathing movements, and one or more breathing signals generated by detecting breathing-related biological characteristics. The breathing signal may be, for example, a signal generated by detecting biological characteristics through voltage (or wireless signal), and the breathing movement may be, for example, an image of chest rise and fall or similar characteristics.

[0050] In more detail, Figure 2 As shown, in a specific embodiment, the atomization device 2 to be tested may be provided with a second sensor 26, and the second sensor 26 is used to detect the user's breathing characteristics different from the above-mentioned, and corresponding to the detected breathing characteristics showing that the user is inhaling, the atomization module 21 is controlled to atomize. The second sensor 26 may be, for example, a sensor for sensing the aforementioned breathing characteristics, such as a sound sensor, an image sensor, an optical sensor, or a wireless signal (such as Wi-Fi, Bluetooth) receiver, etc. Therefore, the breathing characteristic simulator 11 may be, for example, a speaker, a display, a light-emitting device, or a signal generator, corresponding to the way the second sensor 26 detects breathing, and provides corresponding breathing characteristics by means of sound, light, electrical signals, etc., so that the atomization device 2 to be tested can control the atomization module 21 to atomize, thereby achieving the purpose of testing the atomization device 2 to be tested.

[0051] Therefore, if Figure 4 As shown, the test procedure may optionally further include step S40-1: configuring each atomization device to be tested to atomize the test liquid in the liquid container when one or more of the plurality of breathing characteristics are detected, so as to generate aerosol that flows into the main air flow channel.

[0052] It should be noted that in the above embodiments, the breathing simulation system 1 provided by the present invention is provided with the connection pipe 12 and the liquid supply mechanism 16 under the premise of testing multiple atomizing devices 2 to be tested, however, the present invention is not limited thereto. In a specific embodiment, the breathing simulation system 1 may also be provided with only a single connection pipe 12, a liquid supply container 160, a liquid supply tube 162 and a positioning mechanism 19, so as to be suitable for testing a single atomizing device 2 to be tested.

[0053] Advantageous Effects of Embodiments

[0054] One of the beneficial effects of the present invention is that the breathing simulation system provided by the present invention can test a large number of atomization devices to be tested simultaneously, and can also automatically replenish the drug solution and collect the drug mist.

[0055] In addition, the breathing simulation system provided by the present invention can achieve the effect of automatic quantitative drug delivery without designing different quantitative drug delivery conditions for multiple atomization devices to be tested.

[0056] Furthermore, by designing the positioning mechanism, the air inlet and the connecting pipe of the atomizing device to be tested are tilted relative to the ground at a predetermined angle, which can prevent waste liquid from staying in the air inlet and the connecting pipe, thereby providing an automatic waste liquid removal mechanism.

[0057] The contents disclosed above are only preferred feasible embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, all equivalent technical changes made using the contents of the present invention description and drawings are included in the protection scope of the present invention.
