In addition, the respiration sensor 17 records the rotation information including the rate of change of the rotation speed and the rotation speed measured in the measurement module 172, and analyzes to determine the user's breathing pattern based on the rotation information A module 173 may be further included.

The rotation module 171 changes the rotation direction according to the inhalation or exhalation while the user breathes. In this embodiment, the rotation module 171 may use a pinwheel-type FAN. However, the present invention is not limited thereto and may include any form capable of measuring the amount of rotation for respiration detection.

The rotation module 171, in this embodiment, may be rotated clockwise while exhalation is made. In this case, if the inhalation is made, it can be rotated in the opposite direction, counterclockwise or counterclockwise.

The rotation module 171 may be configured to form a flow path between the inner surface and the outer surface of the mask device while breathing is performed to facilitate intake and exhaust. At the point of inhalation and exhalation, the direction can be freely switched between the intake structure and the exhaust structure.

The measurement module 172 may measure the rotation speed of the rotation module 171 and a rate of change of the rotation speed while the rotation module 171 is operating. The measurement module 172 may measure the air in the flow path that changes according to the amount of respiration through the number of rotations of the rotation module 171 .

Analysis module 173, based on the respiration information collected by the rotation module 171 and the measurement module 172 may analyze what the current user's breathing state is. According to the rotation direction, the rotation speed and the rate of change of the rotation speed may be matched and recorded in the database 18 .

The analysis module 173 may divide and subdivide each data measured by the measurement module 172 into steps to record and store it for each individual. In addition, it is possible to generate data by accumulating such data, and then when the user's data is collected, it is possible to determine the current breathing state by comparing it with the stored data.

Hereinafter, a method for controlling a mask apparatus according to an embodiment of the present invention will be described in detail with reference to the drawings.

Figure 17 (A) shows the rotational speed of the rotation module 171 according to the first embodiment of the present invention, Figure 17 (B) shows the amount of respiration during one cycle.

Referring to FIG. 17(A), the rotation module 171 increases and decreases the speed during one cycle of the user's inhalation or exhalation, and the respiration rate during this one cycle is shown as shown in FIG. 17(B). An embodiment of the present invention may provide a control method of a mask device for smoothing the user's breathing according to the change in the amount of respiration.

18 is a flowchart schematically illustrating a method for controlling a mask apparatus according to a first embodiment of the present invention.

Referring to FIG. 18 , in step S11 , the mask device first detects whether the user's breathing state is inhalation or exhalation through the respiration sensor 17 .

Specifically, when the power of the mask device 1 is turned on, the respiration sensor 17 is operated. The rotation module 171 first moves according to the user's breathing without other control, and at this time, the measurement module 172 and the analysis module 173 measure and analyze the movement of the rotation module 171 , respectively.

In the first embodiment of the present invention, it is possible to control to operate the analysis module 173 by checking whether the amount of data is collected enough to determine the user's respiration amount, and the operation of the analysis module 173 rotates the module 171 ), the timing to control the rotation can also be adjusted.

And in step S12, the respiration rate according to the respiration state and the respiration information including the rate of change of the respiration rate is measured. In the case of respiration volume, it is possible to measure through the rotational speed of the rotation module 171, and the rate of change of the respiration rate can be calculated by measuring the change rate of the measured rotational speed at every preset period.

At this time, the respiration sensor 17 can eliminate erroneous detection compared to the case of using the existing sensitive sensors by applying the rotation principle according to the amount of respiration, and since the acceleration is constantly increased or decreased according to the respiration, the noise rotates significantly It does not affect the speed of the module 171 .

In the next step S13, the respiration information is recorded and the user's respiration pattern is determined based on the respiration information. Step S13 will be described later in the detailed flowchart of FIG. 18 .

19 is a flowchart illustrating in detail a method for controlling a mask apparatus according to a first embodiment of the present invention.

Referring to FIG. 19 , the power of the mask device is turned on in step S21, and it is determined whether the current user's respiration is inhalation in step S22. This can be determined by detecting the rotation direction through the rotation state of the rotation module 171 .

In the steps S23 and S24 of the embodiment of the present invention, the rotation module 171 can rotate clockwise in the case of inhalation. This means a clockwise direction from the user's gaze angle, and is not limited thereto, and it is possible to set the rotation direction in which external air is introduced according to the shape of the rotation module 171 . In the case of step S24, it is possible to set a rotational shape opposite to the case of inhalation so that the respiration can be discharged to the outside as a case of not breathing. In addition, if there is no operation of the rotation module 171, it is also possible to stop the operation of the rotation module 171 if it is effective to exhale to the outside. In the case of steps S25 to S27, since they are the same as those described in FIG. 17, their description will be omitted here.

In the case of step S28, the breathing pattern is determined, which will be described with reference to [Table 1] below.

Referring to Table 1, the measurement module 172 may check the speed of the air being breathed in the flow path while respiration is made according to the rotation speed of the rotation module 171 . At this time, the measurement module 172 may check and record the rate of change of the rotational speed every preset period.

At this time, the analysis module 173 may analyze what the current user's breathing state is based on the respiration information, and match the rotational speed and the rate of change of the rotational speed according to the rotational direction and record it in the database 18 .

In addition, the analysis module 173 may calculate the total amount of the intake amount of external air inhaled by the user during one inhalation cycle, and through this, each step of the breathing pattern may be set, and may be utilized for pattern analysis later.

The analysis module 173 may preset a breathing pattern based on each data measured by the measurement module 172, divide it into steps and subdivide it, and record and store it for each individual. Therefore, while the user is breathing, based on the respiration information measured in real time, it is possible to determine which stage of the current user's breathing pattern is step 1 to step 8. If this determination is possible, the following breathing pattern can be predicted, which will be described later with reference to FIG. 20 showing the second embodiment.

20 is a flowchart illustrating a method of controlling a mask apparatus according to a second embodiment of the present invention.

Referring to FIG. 20 , step S39 may be added in addition to the contents described with reference to FIG. 19 . Step S39 is a process of determining whether the breathing direction changes.

Step S39 is a process of controlling the rotation module 171 when the user's breathing pattern is determined in step S38 and the user's breathing pattern is different from the original breathing pattern.

For example, if the user's breathing pattern is an in-breath, if it is determined that it is time to switch to an exhalation based on the respiration information, the rotation module 171 may be stopped or controlled to rotate in the opposite direction to the existing direction. The case of switching from exhalation to inhalation may also be applied. Accordingly, the user is able to breathe smoothly even while wearing the mask device.

Although the present invention has been described in detail through representative embodiments above, those of ordinary skill in the art to which the present invention pertains will understand that various modifications are possible within the limits without departing from the scope of the present invention with respect to the above-described embodiments. will be. Therefore, the scope of the present invention should not be limited to the described embodiments and should be defined by all changes or modifications derived from the claims and equivalent concepts as well as the claims to be described later.
