Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent.

Referring to fig. 1, fig. 1 is a schematic flow chart of a method for adjusting air volume in a mask according to an embodiment of the invention. In this embodiment, the main body of the method for adjusting the air volume in the mask is a mask, such as an intelligent mask, and the method is not limited thereto. The method for adjusting the air quantity in the mask shown in fig. 1 can comprise the following steps:
s101: and acquiring the air pressure value generated by the breathing of the mask worn by the user.
The mask acquires an air pressure value generated when a user wears the mask to breathe. Specifically, the mask may include a plurality of processing units such as a data acquisition unit, an air volume control unit, a respiratory state analysis unit, a state indication unit, an air pressure data processing unit, a core system unit, and the like. The data acquisition unit is used for acquiring the air pressure value in the mask, and comprises the steps of acquiring the air pressure value generated when a user wears the mask to breathe and acquiring the air pressure value in the mask when the user does not wear the mask; the air quantity control unit is used for controlling the air quantity in the mask; the respiratory element analysis unit is used for analyzing the current respiratory state and the smooth respiratory state of the user; such as specifically analyzing whether the user currently belongs to an expiration state or an inspiration state, and analyzing whether the current smooth breathing state of the user is a breath hold state or a choke state. The breath holding state means that the air quantity flowing into the mask from the outside is relatively large, so that the user breathes unevenly, and the air quantity in the mask needs to be reduced at the moment; the choke state means that the air quantity flowing into the mask from the outside is relatively small, so that the breathing of a user is not smooth, and the air quantity in the mask needs to be increased at the moment.
The state indicating unit can be used for indicating whether the mask is in a power-on running state or a standby state or a power-off state currently, and also can be used for indicating the current electric quantity using state of the mask, analyzing the using time of the mask and reminding a user to replace a filter element of the mask. The air pressure data processing unit is used for processing the collected air pressure values, such as averaging operation can be carried out on the collected air pressure values, the air pressure values are compared, and the like; the core system unit can perform data interaction with other units, send various instruction information to other units, and timely execute various control instructions triggered by a user, such as instructions triggered by the user, such as startup and shutdown.
Further, in order to accurately judge the current smooth breathing state of the user according to the collected air pressure value, the follow-up air quantity in the mask can be accurately regulated, and the air pressure value can be collected according to the preset cycle time when being collected. If the air pressure value in the mask is collected every second or every two seconds when the user wears the mask, the user can set and adjust the cycle time according to the actual situation, which is not limited.
S102: determining a current smooth breathing state of the user based on the air pressure value, a preset expiration pressure value and a preset inspiration pressure value; the preset expiration pressure value represents a corresponding pressure value when the user wears the mask to exhale normally; the preset inhalation pressure value represents a corresponding pressure value when the user wears the mask to inhale normally.
The mask determines the current smooth breathing state of the user according to the acquired air pressure value, the preset expiration pressure value and the preset inspiration pressure value generated when the user wears the mask to breathe. The smooth breathing state can be a breath holding state or a choke state, and is used for indicating the specific state when the user currently wears the mask to breathe.
The preset exhalation pressure value represents a pressure value corresponding to the normal breathing of the mask worn by the user. In order to adapt to various occasions, various people can use the mask comfortably, when the preset expiration pressure value is set, the user can set the expiration pressure value in the mask when wearing the mask to breathe normally, or the mask can acquire the expiration pressure value in the mask in a preset period when the user wears the mask to breathe first, average the expiration pressure value acquired in the preset period, and the calculated average value is taken as the preset expiration pressure value. The preset inhalation pressure value represents a corresponding pressure value when the user wears the mask to inhale normally. Accordingly, in order to adapt to various occasions, various people can use the mask comfortably, when the preset inhalation pressure value is set, the inhalation pressure value in the mask can be set by a user when the user wears the mask to breathe normally, or the inhalation pressure value in the mask can be acquired by the mask in a preset time period when the user wears the mask to breathe, the inhalation pressure value acquired in the preset time period is averaged, and the calculated average value is taken as the preset inhalation pressure value. The preset time period is the same as the corresponding preset time period when the expiratory pressure value is acquired, and the specific value can be set and adjusted by a user according to actual conditions, which is not limited.
Specifically, the mask acquires air pressure values generated by breathing of a user wearing the mask in a preset period, wherein the air pressure values comprise an expiration pressure value and an inspiration pressure value, an average value of the air pressure values is calculated, and the calculated average value is recorded as a preset air pressure average value; the obtained air pressure value generated by the breathing of the user wearing the mask is compared with the preset air pressure average value, so that whether the air pressure value belongs to the air pressure value corresponding to the breathing state or the air pressure value corresponding to the inspiration state can be determined. When the air pressure value is the air pressure value corresponding to the expiration state, comparing the air pressure value with a preset expiration pressure value, and determining the current breathing smoothness state of the user according to the comparison result. When the air pressure value is the air pressure value corresponding to the air suction state, comparing the air pressure value with a preset air suction pressure value, and determining the current smooth breathing state of the user according to the comparison result.

Specifically, the mask acquires an air pressure value generated by breathing of a user wearing the mask in a preset period, wherein the air pressure value comprises an expiration pressure value and an inspiration pressure value, calculates an average value of the expiration pressure value and the inspiration pressure value, and marks the calculated average value as a preset air pressure average value. And comparing the obtained air pressure value generated when the user wears the mask to breathe with the preset air pressure average value to obtain a first comparison result. For example, the first comparison result may be that the air pressure value generated by the breathing of the user wearing the mask is greater than the preset air pressure average value; or the air pressure value generated by breathing the mask worn by the user is smaller than the preset air pressure average value; the air pressure value generated by breathing the mask can be equal to the preset air pressure average value.

Further, when the respiratory state is the inhalation state, S1025-S1026 may be further included, and it should be noted that S1023-S1024 is juxtaposed with S1025-S1026, and that S1025-S1026 is not performed after S1023-S1024. And S1023-S1024 or S1025-S1026 are selectively executed according to different execution results of S1022, and the actual situation is subject to no limitation.

Referring to fig. 2, fig. 2 is a schematic flow chart of a method for adjusting air volume in a mask according to another embodiment of the invention. In this embodiment, the main body of the method for adjusting the air volume in the mask is a mask, such as an intelligent mask, and the method is not limited thereto.
The differences between the present embodiment and the previous embodiment are S201-S203, S206-S211, and in this embodiment S204-S205 are identical to S101-S102 in the previous embodiment, and specific reference is made to the description related to S101-S102 in the previous embodiment, which is not repeated here. In order to judge whether the user wears the mask currently, the air quantity in the current mask is accurately regulated for the user when the user wears the mask, and when the user is detected that the user does not wear the mask currently, the operation state of the mask is stopped in time, so that the electric quantity is saved. The embodiment may further include S201 to S203, which are specifically as follows:
s201: acquiring a first preset number of mask air pressure values based on a preset sampling period; the air pressure value of the mask is the air pressure value in the mask.
The mask acquires a first preset number of mask air pressure values based on a preset sampling period. The preset sampling period and the first preset number are set by the user according to the actual situation, and are not limited. For example, the mask may collect air pressure values in the mask once every two seconds for a total of 15 mask air pressure values; the air pressure value in the mask can be collected once every second, and 10 mask air pressure values can be collected in total. The air pressure value of the mask is the air pressure value in the mask, and the air pressure value of the mask obtained here can be the air pressure value generated when the user wears the mask to breathe, or the air pressure value in the mask when the user does not wear the mask; in S101, the air pressure value generated when the user wears the mask and breathes is acquired, and the air pressure value must be the air pressure value generated when the user wears the mask and breathes.
S202: determining the data type of each mask air pressure value based on a preset mask air pressure average value, each mask air pressure value and a preset data type; the preset data type comprises expiration data and inspiration data.
The air pressure average value of the mask is an average value of air pressure values of the mask, which are obtained in a preset period, the air pressure values of the mask in the preset period are obtained by the mask, the average value of the air pressure values is calculated, and the calculated average value is recorded as the air pressure average value of the mask. The preset period is the same as the preset period used for calculating the preset air pressure average value, and is set by a user according to actual conditions, and is not limited. The preset data types comprise expiration data and inspiration data, and are data types corresponding to the air pressure values of each mask, namely whether the air pressure values of the mask belong to expiration data or inspiration data.
Specifically, the air pressure data processing unit in the mask compares the acquired air pressure value of each mask with a preset air pressure average value of the mask to obtain a corresponding comparison result; and determining the data type of each mask air pressure value according to the preset corresponding relation between the comparison result and the preset data type. If the mask air pressure value is larger than or equal to the preset mask air pressure average value, marking the mask air pressure value as expiration data; and when the mask air pressure value is smaller than the preset mask air pressure average value, marking the mask air pressure value as inhalation data.
S203: when a state of increasing the second preset number of expiration data is detected, and the state of decreasing the second preset number of inspiration data is detected, judging that the user wears the mask currently; the second predetermined number is a predetermined percentage of the first predetermined number.
The mask detects whether the mask air pressure value corresponding to each expiration data is increased or decreased relative to the mask air pressure value corresponding to the adjacent previous expiration data, and then judges whether the expiration data are in an incremental state. For example, 20 mask air pressure values are obtained, wherein 10 pieces of exhalation data are respectively 20, 22, 24, 26, 25, 30, 32, 27, 29 and 31 (the units of the mask air pressure values are hundred Pa: hpa), the mask compares the second piece of exhalation data with the adjacent first piece of exhalation data, compares the third piece of exhalation data with the adjacent second piece of exhalation data, and the like, so that the first to fourth pieces of exhalation data, the sixth seventh piece of exhalation data and the ninth piece of exhalation data are respectively presented in an increasing state, and the fifth piece of exhalation data and the eighth piece of exhalation data are respectively reduced, namely 8 pieces of exhalation data in the increasing state.
Similarly, the mask detects whether the mask air pressure value corresponding to each inhalation data is increased or decreased relative to the mask air pressure value corresponding to the previous inhalation data adjacent to the mask air pressure value, and further judges whether the inhalation data are in a descending state. For example, of the 20 mask pressure values obtained, the remaining 10 inhalation data are-22, -24, -26, -27, -28, -26, -25, -29, -31, and-33, respectively. The mask compares the second inhalation data with the adjacent first inhalation data, compares the third inhalation data with the adjacent second inhalation data, and the like, so that the inhalation data in the sequence from the first to the fifth and the eighth to the tenth are in a descending state, and the inhalation data in the sequence from the fifth to the seventh are in an ascending state, namely 8 inhalation data in the batch of inhalation data are in a descending state.
The first preset number, the second preset number and the preset percentage are set by the user, and the second preset number can be adjusted according to the first preset number, the second preset number occupies the preset percentage of the first preset number, and the method is not limited. And when the mask detects that the second preset number of expiration data is in a state of increasing presentation and the second preset number of inspiration data is in a state of decreasing presentation, judging that the user wears the mask at the moment. For example, the air pressure values of the 20 masks are in an increasing state, 8 data in expiration data are in a decreasing state, the pressure values of the 8 data in inspiration data are in accordance with the pressure value change condition generated by breathing of the user when the user wears the masks, and the current user is judged to wear the masks. If the user does not wear the mask, the obtained mask air pressure value basically does not change, and the mask can judge that the user does not wear the mask currently.
Further, when it is determined that the current user wears the mask, S204-S205 are executed after S203, in this embodiment, S204-S205 are identical to S101-S102 in the previous embodiment, and detailed descriptions of S101-S102 in the previous embodiment are omitted herein.
Further, in order to accurately and rapidly adjust the air volume in the mask, and improve the comfort level when the user wears the mask, S206-S208 may be further included after S205, which specifically includes the following steps:
s206: and when the smooth breathing state is a breath holding state, calculating a first difference value between the air pressure value and the preset expiration pressure value, and acquiring a breath holding degree value corresponding to the first difference value.
When the smooth breathing state of the user is the breath holding state, the mask calculates a first difference value between the air pressure value and a preset expiration pressure value at the moment, and acquires a breath holding degree value corresponding to the first difference value. The core system unit in the mask stores a file related to the breath holding state, different difference values and corresponding breath holding degree values thereof are stored in the file in advance, and the different difference values can correspond to the same breath holding degree value, for example, the breath holding degree values corresponding to the difference values 1 and 2 can be 1, and the breath holding degree values corresponding to the difference values 3 and 4 can be 2, which is not limited. When the smooth breathing state is the breath holding state, the file is found first, and then the breath holding degree value corresponding to the first difference value is found. For example, when the smooth breathing state of the user is a breath holding state, the preset expiration pressure value is 20, and when the air pressure value at the moment is 22, a first difference value between the air pressure value and the preset expiration pressure value is calculated to be 2, and a breath holding degree value corresponding to the first difference value is obtained by searching to be 1; when the smooth breathing state of the user is the breath holding state, the preset expiration pressure value is 20, and when the air pressure value at the moment is 24, a first difference value between the air pressure value and the preset expiration pressure value is 4, and the breath holding degree value corresponding to the difference value is 2 through searching.
S207: and acquiring a first air volume adjusting speed corresponding to the breath holding degree value and acquiring a first air volume range corresponding to the air pressure value.
The mask is pre-stored with an air volume adjusting speed corresponding to each breath holding degree value and an air volume range corresponding to each air pressure value. The mask acquires a first air volume adjusting speed corresponding to the breath holding degree value, and acquires a first air volume range corresponding to the air pressure value at the moment. For example, when the air-holding degree value is 1, searching to obtain a first air volume adjusting speed corresponding to the air-holding degree value as 1, and further obtaining a first air volume range corresponding to the air pressure value as A-B; when the air-holding degree value is 2, searching to obtain a first air volume adjusting speed corresponding to the air-holding degree value to be 2, and further obtaining a first air volume range corresponding to the air pressure value to be C-D. Further, in order to reduce the pressure of the mask storage data, a first air volume range corresponding to the air pressure value in the preset range can be set, the mask can judge in which preset range the air pressure value is in, and the first air volume range corresponding to the preset range can be further searched.
S208: and regulating the current air quantity in the mask to be within the first air quantity range at the first air quantity regulating speed.
The mask adjusts the current air quantity in the mask to be within a first air quantity range at a first air quantity adjusting speed. Specifically, the mask is provided with a fan, and the air quantity control unit can control the rotating speed of the fan and control the air inlet or the air outlet of the fan, which is equivalent to controlling whether the mask increases the air quantity or decreases the air quantity; the speed of increasing or decreasing the air quantity can also be adjusted. For example, when the first air volume adjusting speed is 1 and the first air volume range corresponding to the current air pressure value is A-B, the mask controls the fan to perform air exhaust operation through the air volume control unit, the rotating speed of the fan is adjusted to be 1, the air volume in the mask is reduced at the speed, and the current air volume in the mask is adjusted to be A-B; when the first air volume adjusting speed is 2 and the first air volume range corresponding to the current air pressure value is C-D, the mask adjusts the rotating speed of the fan to be 2 through the air volume control unit, reduces the air volume in the mask at the speed, and adjusts the current air volume in the mask to be C-D. This is merely illustrative and is not limiting.
Further, in order to accurately and rapidly adjust the air volume in the mask and improve the comfort level when the user wears the mask, S209-S211 may be further included after S205, and it should be noted that S209-S211 are not executed after S208, but after S205 are executed, S206-S208 or S209-S211 are selectively executed according to different execution results, which is specific to the actual situation. S209 to S211 are specifically as follows:
S209: and when the smooth breathing state is a stuffy state, calculating a second difference value between the air pressure value and the preset inhalation pressure value, and obtaining a stuffy degree value corresponding to the second difference value.
When the smooth breathing state of the user is a choke state, the mask calculates a second difference value between the air pressure value and the preset inhalation pressure value at the moment, and obtains a choke degree value corresponding to the second difference value. The core system unit in the mask stores a file related to the choke status, and the file stores different difference values and corresponding choke values in advance, and the different difference values can correspond to the same choke value, which is not limited. When the smooth breathing state is a stuffy state, the file is found first, and then the stuffy degree value corresponding to the second difference value is found. For example, when the smooth breathing state of the user is a choke state, the preset inhalation pressure value is-25, and the air pressure value at the moment is-31, a second difference value between the air pressure value and the preset inhalation pressure value is calculated to be 6, and a choke degree value corresponding to the second difference value is obtained by searching for 3.
S210: and obtaining a second air volume adjusting speed corresponding to the choke valve and a second air volume range corresponding to the air pressure value.
The mask is stored with air volume adjusting speed corresponding to each choke valve and air volume range corresponding to each air pressure valve. The mask acquires a second air volume adjusting speed corresponding to the choke valve and acquires a second air volume range corresponding to the air pressure value at the moment. The first air volume adjustment speed and the second air volume adjustment speed may be the same or different, and are not limited in terms of actual conditions. For example, when the choke valve is 3, the second air volume adjusting speed corresponding to the choke valve is found to be 3, and the second air volume range corresponding to the air pressure value at this time is obtained to be E-F. This is merely illustrative and is not limiting.
S211: and regulating the current air quantity in the mask to be within the second air quantity range at the second air quantity regulating speed.
The mask adjusts the current air quantity in the mask to be within a second air quantity range at a second air quantity adjusting speed. Specifically, the air quantity control unit can control the fan to perform air inlet operation and adjust the air quantity in the current mask. For example, when the second air volume adjusting speed is 3 and the second air volume range corresponding to the current air pressure value is E-F, the mask adjusts the rotating speed of the fan to be 3 through the air volume control unit, and the air volume in the mask is increased at the speed, so that the current air volume in the mask is adjusted to be E-F. This is merely illustrative and is not limiting.
According to the embodiment of the application, the mask acquires the air pressure value generated by breathing of the user wearing the mask, and judges the air pressure value to obtain the current smooth breathing state of the user, so that the air quantity in the current mask is regulated according to the smooth breathing state. The air quantity in the mask can be adjusted according to different pressure values generated by the breathing of the user wearing the mask, so that the air quantity in the mask is in a quantity which enables the user to breathe smoothly, and further the user cannot feel choked no matter what occasion the user wears the mask, and wearing comfort is improved.
