【Detailed ways】

In order to make the objects, technical solutions, and advantages of the present application more comprehensible, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specifics described herein The examples are only used to explain the present application and are not intended to limit the application.

FIG. 1 is a schematic structural view of a snoring pillow according to an embodiment of the present application.

As shown in FIG. 1, the snoring pillow 10 includes a processor 101, an inflator 102, a deflation device 103, and an air bag 104. The inflator 102 and the deflation device 103 are coupled to the air bag 104. The airbag 104 has at least one air inlet (not shown) and one air outlet (not shown), and the air inlet of the airbag 104 is connected to the inflator 102, and the air outlet of the airbag 104 is connected to the air venting device 103.

The inflator 102 is used to inflate the air bag 104. Specifically, the inflator 102 may include an inflation valve, an air pump, an inflation tube, and the like to achieve an increase in air pressure of the air bag.

The deflation device 103 is for discharging the gas in the airbag 104. Specifically, the deflation device may include a deflation valve, a vacuum pump, and the like to achieve a reduction in air pressure of the air bag.

The processor 101 is configured to control the inflator 102 to inflate the airbag 104 until the first preset stop condition is satisfied; and to control the deflation device 103 to perform stepwise deflation on the airbag 104 until the second pre-fill is satisfied. When the stop condition is set, the airbag 104 is stopped from deflation.

In this embodiment, the first preset stop condition is that the processor controls the inflator to stop the inflating condition of inflating the airbag 104. The second preset stop condition is a condition in which the processor controls the deflation device to stop deflation of the air bag. Stopping the inflation means that the inflation is completed. If the pause inflation occurs at some time during the start of inflation to the completion of the inflation, the pause inflation is not counted as stopping the inflation. Similarly, stopping the deflation means that the deflation is completed, and at the beginning, If the deflation occurs at some point during the completion of the gas to deflation, the deflation is not counted as stopping deflation.

The shackle pillow 10 can change the shape of the airbag 104 to change the sleeping position of the user to achieve the purpose of stopping the snoring. Specifically, when the user's snoring is detected, the processor 101 controls the inflator 102 to inflate the airbag 104. The air pressure in the air bag 104 is increased to change the shape of the air bag 105, and the processor 101 controls the inflator 102 to stop inflating when the first preset stop condition is satisfied. Further, the processor 101 controls the deflation device 103 to step out the gas in the airbag 104, the air pressure in the airbag 104 is reduced, and the shape of the airbag 104 is changed again until the second preset stop condition is satisfied, and the processor 101 controls. The deflation device 103 stops deflation, and the airbag 104 is inflated and deflated to change the posture of the user's head, thereby achieving stagnation.

Since the height of the airbag 104 has a corresponding relationship with the air pressure of the airbag 104, when the air pressure of the airbag 104 is higher, the corresponding height is higher, and the airbag 104 is stepped deflated so that the airbag 104 is The air pressure changes stepwise with time, and the height of the corresponding airbag also changes stepwise. The processor 101 controls the deflation device 103 to step out the gas in the airbag 104, which can reduce the discomfort caused by the airbag 104 falling during the deflation process, as the user's head falls down with the height of the airbag 104. Please refer to Fig. 2, point a to point A in Fig. 2 is the curve of the air pressure inflation process, point I to point i is the curve of the air pressure deflation process, between f and g, and between g and h In the case where the air pressure does not change, there is a pause in deflation of the airbag. During the deflation process, the pause and deflation of the airbag may cause the user's head to descend during the process of descending with the height of the airbag, so as to reduce the user's head from directly falling from the highest point to the lowest point. The resulting sense of fall, thereby avoiding the situation of easily waking up the user during the adjustment of the user's sleeping position. It should be noted that, in FIG. 2, the air pressure of the airbag is changed stepwise by suspending one or more deflations during the deflation process, and the step deflation is only realized in the embodiment of the present application. The skilled person in the field can also realize the step deflation by other means, for example, adjusting the rate of deflation to realize the step deflation, firstly using the lower deflation rate for deflation at the beginning of deflation, and achieving slow deflation, when slowly releasing When the gas reaches the set node, the gas is deflated at a higher deflation rate to achieve rapid deflation, and the feeling of falling from the lowest point of the user's head from the highest point is avoided. Of course, in the deflation process, the stepwise change of the air pressure realizes the stepwise change of the height of the airbag, thereby improving the comfort of the user's head when adjusting the user's sleeping posture, and the technical solution for avoiding the fall feeling should fall into the process. The scope of protection of this application.

In the embodiment of the present application, the airbag is stepped deflated during the deflation of the airbag, on the one hand, the deflation action for deflation of the airbag is enriched, and on the other hand, the fall of the user's head due to deflation is also reduced. The sense, so that by adjusting the height of the airbag, the user's head during the snoring process of the user is more comfortable, and the interference to the user is reduced.

In some embodiments, the second predetermined stopping condition during the deflation of the airbag may be that the processor controls the deflation time of the deflation device from the process of starting deflation to the airbag to stopping deflation to a preset length of time. The deflation time is specifically the time interval from when the airbag starts to deflate until the deflation is stopped. The preset duration is the length of time required for the height of the airbag to drop from the preset highest point to the preset lowest point when the airbag is normally deflated. In other embodiments, if the duration of each stage is fixed during the deflation process, the condition of stopping the deflation may also be met by directly detecting the deflation duration of the last stage to satisfy a duration threshold.

Since the preset duration is the normal deflation of the airbag, the height of the airbag is lowered from the preset highest point to the preset The time required for the lowest point, wherein the air pressure corresponding to the highest point of the airbag is called the preset maximum air pressure, and the air pressure corresponding to the height of the airbag at the preset lowest point is called the preset minimum air pressure. In an ideal state, after the airbag is deflated to a preset length, its air pressure should be equal to the preset minimum air pressure value. However, in the actual deflation process, if the gas path is abnormal, the air bag will be deflated for a preset period of time, and the air pressure of the air bag will deviate from the preset minimum air pressure. In other words, the air pressure after the preset time of the air bag can be deflated. The preset minimum air pressure is compared to detect whether the air passage of the airbag is normal.

Specifically, please refer to FIG. 3. FIG. 3 is a schematic structural diagram of a snoring pillow 30 according to another embodiment of the present application. The difference between the embodiment and the above embodiment is that the snoring pillow 30 further includes:

The detecting device 305 is connected to the air bag 304 for detecting the air pressure of the air bag 304. Specifically, the detecting device is a device capable of detecting air bag pressure change data, for example, an air pressure sensor.

After the deflation of the air bag 304 is stopped, the processor 301 is further configured to: control the detecting device 305 to detect the first air pressure of the air bag 304, and if the first air pressure of the air bag 304 is not within the preset minimum air pressure range, determine the air bag 304. The air path is abnormal. If the first air pressure of the air bag 304 is within the preset minimum air pressure range, it is determined that the air path of the air bag 304 is normal.

Since the air pressure of the airbag is always in a reduced state during the deflation, the first air pressure can be regarded as the air pressure value after the preset time of the airbag deflation in the actual deflation process, that is, the air pressure value at the I point shown in FIG. Since it is difficult to accurately control the deflation, if only one point value of the preset minimum air pressure is used as the judgment standard, it is easy to increase the probability of false alarm abnormality. Therefore, a preset minimum air pressure range is introduced, wherein the preset minimum air pressure range is Refers to the pressure range of 10% floating around the preset minimum air pressure, which is [preset minimum air pressure * 90%, preset minimum air pressure * 110%]. When the processor 301 controls the detecting device 305 to detect that the first air pressure of the airbag 304 is within the preset minimum air pressure range, the processor 301 determines that the first air pressure is within the allowable range, and confirms that the air passage of the airbag is normal.

It is worth noting that although the second preset stop condition described above is that the deflation time from the start of deflation of the airbag to the stop of deflation reaches a preset duration, it is not intended to limit the second preset stop. The deflation time from the start of deflation of the airbag to the stop of deflation reaches a preset length of time, and those skilled in the art can also set other stop conditions according to actual conditions, for example, the height of the airbag detected by the height detector is the preset minimum. The point is used as the second preset stop condition or the like.

In some embodiments, the first preset stop condition during inflation of the airbag may be: the air pressure of the airbag is a preset maximum air pressure, and the preset maximum air pressure is when the height of the airbag reaches a preset maximum point. Corresponding air pressure. During the inflation process, in order to prevent the air pressure of the airbag from instantaneously reaching the preset maximum air pressure (point A in Fig. 2), the user is easily awakened, and the airbag can be controlled to inflate at least at a rate from the start of inflation to the stop of inflation. Changing once, and more preferably, the inflation rate changes from high to low during inflation, and the step of the processor 301 controlling the inflator 302 to inflate the airbag 304 specifically includes: the processor 301 controls the inflator 302 to follow the first inflation. At a rate, the air bag 304 is inflated to an intermediate air pressure; and the inflator 302 is controlled to inflate the air bag 304 from the intermediate air pressure to a preset maximum air pressure at a second inflation rate, wherein the first inflation rate is greater than the second inflation rate.

As the inflation rate is larger, the larger the inflation amount, the faster the height of the airbag changes. At the beginning of the inflation, the airbag is at the preset lowest point. At this time, the airbag is inflated at a faster speed, and the height of the airbag rises rapidly. When the air pressure reaches the intermediate air pressure, the air is inflated at a slower speed, and the height of the airbag rises slowly, so that the user's head comfort is increased during the process of raising the user's head, and the interference to the user is reduced. The intermediate air pressure can be set to 80% of the preset maximum air pressure, and can also be other air pressure values or other air pressure ranges, which are not limited herein.

Of course, during inflation, the processor 301 can also control the inflation rate of the inflator 302 to change in other ways. For example, during inflation, the inflation rate of the inflator 302 is controlled to decrease, and when the preset maximum pressure is reached, the inflation rate is decreased. Zero, stop inflation, or alternatively, control the inflator 302 to include 3 or more changes in inflation rate during inflation. Any technical solution to improve the comfort of the user's head by changing the inflation rate during the inflation process should fall within the scope of protection of the present application.

It should be noted that although the first preset stop condition described above is that the air pressure of the airbag is the preset maximum air pressure, it is not intended to limit the first preset stop, only the air pressure of the airbag is the preset maximum air pressure, and the prior art The person can also set other stop conditions according to the actual situation, for example, the altitude detector detects that the height of the airbag is the preset highest point as the first preset stop condition.

In the normal airway of the airbag, since the change of the inflation rate is fixed, and the inflation rate of each stage is also fixed, the normal time required for the height of the airbag to reach the preset highest point from the preset lowest point is also fixed. In other words, if the inflation time is the same as the normal length, the air passage of the airbag is normal. Conversely, if the inflation time is different from the normal length, the air passage of the airbag is abnormal, and therefore, the airbag is inflated. Inflation overtime check can be performed during the process In order to detect whether the air path of the air bag is abnormal, specifically, the processor 301 is further configured to record the inflation time length of the air bag 304 to start inflating to stop the inflation, and determine the air path abnormality of the air bag 304 when the inflation time is greater than or equal to the duration threshold. When the inflation time is less than the duration threshold, it is determined that the air passage of the airbag 304 is normal.

It should be noted that it is difficult to accurately control the inflation. If only one point value of the normal duration is used as the criterion, it is easy to increase the probability of false alarm abnormality. Therefore, the threshold length range is introduced, wherein the duration threshold range refers to The range of 10% of the normal time is about [normal time length *90%, normal time length *110%], and when the inflation time is within the duration threshold range, the inflation time is considered to be within the allowable range of the error, the airbag The gas path is normal.

In order to further detect the abnormality of the airway, after stopping the inflation of the airbag, the processor 301 is further configured to control the detecting device 305 to detect the second air pressure of the airbag 304 before starting to deflate the airbag, if the second air pressure is not in advance The gas path abnormality of the air bag 304 is determined within the highest air pressure range, and if the second air pressure is within the preset maximum air pressure range, the air path of the air bag 304 is determined to be normal.

After the airbag is inflated, the airbag is in a maintained state before the airbag is stepped out. When the airbag is in a normal state, the airbag air pressure does not change, and the air pressure in the airbag should be pre-empted. The maximum air pressure is the same. Similarly, if only one point value corresponding to the preset maximum air pressure is used as the judgment standard, it is easy to increase the probability of false alarm abnormality. Therefore, it is more reasonable to introduce the preset maximum air pressure range as a condition.

In order to further increase the comfort of the head during the air-filling and deflation of the airbag, after the airbag 304 stops inflating, before the stepped deflation, the state of the preset interval is maintained after the airbag stops inflating (point A to point I in Fig. 2). The duration of the time period is that when the interval of detecting the distance to stop the inflation of the airbag reaches a preset interval time, the airbag is stepped deflated. The preset interval can be 150s to 180s, and can also be changed according to the actual user's sleep habits, but it is not easy to maintain the time too long, and the head will be uncomfortable if it is too long.

In the embodiment of the present application, by enriching the action of the airbag, for example, the rate of the inflation process is changed at least once, and the deflation process adopts stepped deflation, etc., so that the airbag pushes the head of the human body to be more relaxed when it is deflected, so as to reduce the user's head during the squatting process. The interference of the department is not easy for the user to wake up. Moreover, in the embodiment of the present application, when a completed airbag operation is performed, the air pressure of the airbag is detected and monitored in real time, and the airway fault of the airbag can be found in advance to eliminate hidden dangers.

Whether these functions are performed in hardware or software depends on the specific application and design constraints of the solution. A person skilled in the art can use different methods to implement the described functions for each particular application, but such implementation should not be considered to be beyond the scope of the present application. In short, the processor can also be implemented in hardware or in a computational software implementation. For convenience of the reader, the software implementation of the processor will be described below. Referring to FIG. 4, the snoring pillow 40 includes an air bag (not shown), an inflator 401, a deflation device 402, a processor 403, and a memory 404.

It is a program instruction that implements the functions performed by the processor in the above embodiment. Of course, when it is required to detect the air pressure of the airbag, the shackle pillow should also include a detecting device. Specifically, please refer to FIG. 5, and FIG. 5 is another application of the present application. An embodiment of the present invention is different from the above embodiment in that the shackle pillow 50 further includes a detecting device 505 for detecting the air pressure of the air bag, and the detecting device 505 and the processor 503. Connected, the processor 503 controls the detecting means to detect the air pressure of the airbag by executing a program command.

The above-mentioned shackle pillow can perform the method provided by the embodiment of the present application, and has the corresponding functional modules and beneficial effects of the execution method. For technical details that are not described in detail in this embodiment, reference may be made to the method provided by the embodiments of the present application.

The anti-snoring pillow provided by the embodiment: by enriching the movement of the air bag, for example, the rate of the inflation process is changed at least once, and the deflation process adopts a stepped deflation, so that the airbag pushes the head of the human body to be more relaxed, so as to reduce the stagnation process. In the interference to the user's head, the user is not easily awake. Moreover, in the embodiment of the present application, when a completed airbag operation is performed, the air pressure of the airbag is detected and monitored in real time, and the airway fault of the airbag can be found in advance to eliminate hidden dangers.

The embodiment of the present application provides a non-transitory computer readable storage medium storing computer-executable instructions that are executed by one or more processors, such as in FIG. The processor 503 is configured to enable the one or more processors to perform the method of stopping in any of the foregoing method embodiments, for example, performing the method steps of FIG. 6 to FIG. 10 described above to implement the functions of the processor. In order to achieve the following effects: by enriching the movement of the airbag, for example, the rate of the inflation process is changed at least once, and the deflation process adopts stepped deflation, etc., so that the airbag pushes the head of the human body to be deflected more comfortably, so as to reduce the user during the squatting process.

Moreover, in the embodiment of the present application, when a completed airbag operation is performed, the air pressure of the airbag is detected and monitored in real time, and the airway fault of the airbag can be found in advance to eliminate hidden dangers.

FIG. 6 is a schematic flow chart of an airbag-based stagnation method provided by an embodiment of the present application. As shown in FIG. 6, the stopping method includes:

Step 601: Inflating the airbag until the first preset stop condition is met, and stopping the inflation;

The first preset stop condition is a stop condition for stopping the inflation of the airbag.

Step 602: Perform stepwise deflation on the airbag until the second preset stop condition is met, and stop the airbag from being discharged;

The second preset stop condition is a stop condition for stopping the deflation of the airbag.

Stopping the inflation means that the inflation is completed, at some point in the process of starting the inflation to the completion of the inflation. Suspension inflation occurs, and the pause inflation is not counted as stopping inflation. Similarly, stopping deflation means that deflation is completed, and if deflation occurs at some time during the process of starting deflation to deflation, the suspension is suspended. Deflating is not counted as stopping deflation.

In order to reduce the discomfort caused by the user's head falling in the process of deflation during the deflation of the airbag, the present embodiment controls the airbag to adopt a stepped deflation. The height of the airbag has a corresponding relationship with the air pressure of the airbag. When the air pressure of the airbag is higher, the corresponding height is higher. The stepwise deflation of the airbag causes the air pressure of the airbag to change stepwise, and the height of the corresponding airbag is also stepped. For the change, please refer to Fig. 2. In Fig. 2, point a to point A is the curve of the air pressure inflation process, point I to point i is the curve of the air pressure deflation process, between f and g, and, g and h There is a case where the air pressure does not change, that is, there is a pause in deflation of the airbag. During the deflation process, the pause and deflation of the airbag may cause the user's head to descend during the process of descending with the height of the airbag, so as to reduce the user's head from directly falling from the highest point to the lowest point. The resulting sense of fall, thereby avoiding the situation of easily waking up the user during the adjustment of the user's sleeping position. It should be noted that, in FIG. 2, the air pressure of the airbag is changed stepwise by suspending one or more deflations during the deflation process, and the step deflation is only realized in the embodiment of the present application. The skilled person in the field can also realize the step deflation by other means, for example, adjusting the rate of deflation to realize the step deflation, firstly using the lower deflation rate for deflation at the beginning of deflation, and achieving slow deflation, when slowly releasing When the gas reaches the set node, the gas is deflated at a higher deflation rate to achieve rapid deflation, and the feeling of falling from the lowest point of the user's head from the highest point is avoided. Of course, in the deflation process, the stepwise change of the air pressure realizes the stepwise change of the height of the airbag, thereby improving the comfort of the user's head when adjusting the user's sleeping posture, and the technical solution for avoiding the fall feeling should fall into the process. The scope of protection of this application.

In some embodiments, the second predetermined stop condition during the deflation of the airbag may be that the deflation time from the start of deflation of the airbag to the stop of deflation reaches a preset length of time. The deflation time is specifically the time interval from when the airbag starts to deflate until the deflation is stopped. The preset duration is the length of time required for the height of the airbag to drop from the preset highest point to the preset lowest point when the airbag is normally deflated. Other In the embodiment, if the duration of each stage is fixed during the deflation process, the condition for stopping the deflation can also be stopped by directly detecting that the deflation time in the last stage satisfies a duration threshold.

The preset time is the length of time required for the height of the airbag to drop from the preset highest point to the preset lowest point when the airbag is normally deflated. The air pressure corresponding to the highest point of the airbag is called the preset maximum air pressure. The air pressure corresponding to the lowest point of the preset is called the preset minimum air pressure. In an ideal state, after the airbag is deflated to a preset length, its air pressure should be equal to the preset minimum air pressure value. However, in the actual deflation process, if the gas path is abnormal, the air bag will be deflated for a preset period of time, and the air pressure of the air bag will deviate from the preset minimum air pressure. Conversely, the air pressure after the preset time of the air bag can be deflated. The preset minimum air pressure is compared to detect whether the air passage of the airbag is normal. For details, please refer to FIG. 7. FIG. 7 is a schematic flowchart of a method for stopping the airbag based on another embodiment of the present application. The difference between the above embodiments is that after the step of stopping the deflation of the airbag, the method further comprises:

Step 603: detecting a first air pressure of the airbag;

Since the air pressure of the airbag is always in a reduced state during the deflation, the first air pressure can be regarded as the air pressure value after the preset time of the airbag deflation in the actual deflation process, that is, the air pressure value at the I point shown in FIG.

Step 604: determining whether the first air pressure of the airbag is within a preset minimum air pressure range, and if so, proceeding to step 605, otherwise, proceeding to step 606;

Step 605: Determine that the air path of the air bag is normal;

Step 606: Determine that the air passage of the airbag is abnormal.

Since it is difficult to accurately control the deflation, if only one point value of the preset minimum air pressure is used as the judgment standard, it is easy to increase the probability of false alarm abnormality. Therefore, a preset minimum air pressure range is introduced, wherein the preset minimum air pressure range is Refers to the pressure range of 10% floating around the preset minimum air pressure, which is [preset minimum air pressure * 90%, preset minimum air pressure * 110%], when the first air pressure is within the preset minimum air pressure range, it is considered that the error is at Within the allowable range, confirm that the air passage of the air bag is normal.

In some embodiments, the first preset stop condition during inflation of the airbag may be: the air pressure of the airbag is a preset maximum air pressure, and the preset maximum air pressure is a corresponding air pressure when the height of the airbag reaches a preset highest point. During the inflation process, in order to prevent the air pressure of the airbag from instantaneously reaching the preset maximum air pressure (point A in Fig. 2), the user is easily awakened, and the airbag can be controlled to inflate at least at a rate from the start of inflation to the stop of inflation. Change once, and more preferably, during the inflation process, the inflation rate changes from high to low, as shown in FIG. 8, step 601 includes:

Step 6011: Inflating the airbag according to the first inflation rate, inflating the airbag to the intermediate air pressure;

Step 6012: Inflating the airbag according to the second inflation rate, and stopping inflation when inflating the airbag from the intermediate air pressure to a preset maximum air pressure, wherein the first inflation rate is greater than the second inflation rate.

As the inflation rate is larger, the larger the inflation amount, the faster the height of the airbag changes. At the beginning of the inflation, the airbag is at the preset lowest point. At this time, the airbag is inflated at a faster speed, and the height of the airbag rises rapidly. When the air pressure reaches the intermediate air pressure, it is inflated at a slower speed, and the height of the airbag rises slowly, so that the user's head comfort is increased during the process of raising the user's head, and the interference to the user is reduced. The intermediate air pressure can be set to 80% of the preset maximum air pressure, and can also be other air pressure values or other air pressure ranges, which are not limited herein.

Of course, during the inflation process, the change of the inflation rate may be other ways. For example, during the inflation process, the inflation rate is always reduced. When the preset maximum air pressure is reached, the inflation rate is reduced to zero, the inflation is stopped, or, during the inflation process. Medium, including 3 or more changes in the inflation rate. Any technical solution to improve the comfort of the user's head by changing the inflation rate during the inflation process should fall within the scope of protection of the present application.

It should be noted that although the first preset stop condition described above is that the air pressure of the airbag is the preset maximum air pressure, it is not intended to limit the first preset stop, only the air pressure of the airbag is the preset maximum air pressure, and the prior art The person can also set other stop conditions according to the actual situation, for example, the altitude detector detects that the height of the airbag is the preset highest point as the first preset stop condition and the like.

In the normal airway of the airbag, since the change of the inflation rate is fixed, and the inflation rate of each stage is also fixed, the normal time required for the height of the airbag to reach the preset highest point from the preset lowest point is also fixed. In other words, if the inflation time is the same as the normal length, the airflow of the airbag is normal. Conversely, if the inflation time is different from the normal duration, then The gas path of the airbag is abnormal. Therefore, during the inflation process of the airbag, the inflation timeout detection may be performed to detect whether the airway of the airbag is abnormal. For details, please refer to FIG. 9. FIG. 9 is a schematic diagram of another embodiment of the present application. A flow chart of a method for the stagnation of the airbag is used. The difference between the embodiment and the embodiment is that after the step 601, the method further includes:

Step 607: Record the duration of the inflation;

The length of inflation refers to the length of time from when the airbag begins to inflate to stop inflating, and even if the process of inflating the airbag to stop inflation includes suspending inflation, the duration of the pause inflation is also included in the inflation duration.

Step 608: determining whether the inflation duration is within the duration threshold range, and if yes, proceeding to step 609, otherwise proceeding to step 610;

Step 609: Determine that the air path of the air bag is normal;

Step 610: Determine that the air passage of the airbag is abnormal.

It should be noted that it is difficult to accurately control the inflation. If only one point value of the normal duration is used as the criterion, it is easy to increase the probability of false alarm abnormality. Therefore, the threshold length range is introduced, wherein the duration threshold range refers to The range of 10% of the normal time is about [normal time length *90%, normal time length *110%]. When the inflation time is within the threshold of the duration, it is considered that the air path of the airbag is within the allowable range of the error. normal.

In order to further detect the abnormality of the air passage, after the step of stopping the inflation of the airbag, before starting the stepwise deflation of the airbag, as shown in FIG. 10, the method further includes:

Step 611: detecting a second air pressure of the airbag;

After the airbag is inflated, the airbag is in a maintained state before the airbag is stepped deflated, and the second air pressure can be regarded as the pressure value of the airbag in the maintenance state, that is, between point A and point I in FIG. .

Step 612: Determine whether the second air pressure is within the preset maximum air pressure range, and if yes, proceed to step 613, otherwise proceed to step 614;

Step 613: determining that the air path of the air bag is normal;

Step 614: Determine that the air passage of the airbag is abnormal.

When the airbag is in the maintenance state, if the air passage of the airbag is normal, the air pressure of the airbag does not change, and the air pressure in the airbag should be the same as the preset maximum air pressure, if only a point value corresponding to the preset maximum air pressure is used. As a criterion, it is easy to increase the probability of false positives. Therefore, It is more reasonable to introduce a preset maximum air pressure range as a condition.

In order to further increase the comfort of the head during the air-filling and deflation of the airbag, before the airbag is stopped and inflated, the method further includes: maintaining the preset interval time of the airbag after the airbag stops inflating (A in FIG. 2) The time to point to point I), ie. Of course, the preset interval may be 150s to 180s, or may be changed according to actual user sleep habits, but it is not easy to maintain the time too long, and the head may be uncomfortable if it is too long.

In the embodiment of the present application, by enriching the action of the airbag, for example, the rate of the inflation process is changed at least once, and the deflation process adopts stepped deflation, etc., so that the airbag pushes the head of the human body to be more relaxed, so as to reduce the user during the squatting process. The interference of the head is not easy for the user to wake up. Moreover, in the embodiment of the present application, when a completed airbag operation is performed, the air pressure of the airbag is detected and monitored in real time, and the airway fault of the airbag can be found in advance to eliminate hidden dangers.

It should be noted that the above various embodiments do not exist separately, and the technical features between the various embodiments can refer to each other to complete different functions without conflicting premise, and the positions can also be adjusted between the respective functional modules and method steps.

The above is only the preferred embodiment of the present application, and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection of the present application. Within the scope.
