And S3, controlling the second air bag group 19 arranged at the position of the elastic belt connected with the buckle 18 to expand and abut against the skin of the user.
At S3, specifically, after the buckle fastener 17 is completely contracted, the second airbag module 36 included in the processing chip 3 controls the second airbag module 19 disposed at the position of the elastic band connected to the buckle 18 to expand and collide with the skin of the user, so as to prevent the elastic band from abrading the skin of the user after the user wears the mask for a long time.
And S4, analyzing the behavior information of the user in real time according to the external image and analyzing whether the user places food at the front end of the mask or not in real time according to the behavior information.
In S4, specifically, after the second airbag module 19 is inflated, the behavior analysis module 37 included in the processing chip 3 analyzes the behavior information of the user in real time according to the external image, and the information analysis module 33 analyzes whether the user has placed food at the front end of the mask in real time according to the behavior information, that is, whether the user is ready to eat food.
And S5, if so, controlling the third air bag group 20 arranged on the lower contour in the upper section 10 of the intelligent mask to expand to abut against the skin of the lips of the user and controlling the rotating mechanism 21 arranged in the middle of the intelligent mask to drive the upper half part of the lower section 11 of the intelligent mask connected with the rotating mechanism to rotate and descend so as to expose the mouth of the user.
In S5, specifically, after the information analysis module 33 analyzes that the user has placed food on the front end region of the mask, the third airbag module 38 included in the processing chip 3 controls the third airbag group 20 disposed on the lower contour of the interior of the upper region 10 of the smart mask to expand to collide with the skin of the lips of the user, so as to separate the nose region and the mouth region of the user; after the third airbag unit 20 is inflated, the rotation control module 39 included in the processing chip 3 controls the rotation mechanism 21 disposed in the middle of the smart mask to drive the upper half portion of the lower section 11 of the smart mask connected thereto to rotate and descend so as to expose the mouth of the user.
And S6, analyzing whether the user eats the food or cancels the placement of the food at the front end of the mask in real time according to the behavior information.
In S6, specifically, after the rotation mechanism 21 drives the lower section 11 of the smart mask to rotate, the information analysis module 33 analyzes whether the user has eaten food or placed the food at the front end of the smart mask in real time according to the behavior information.
And S7, if so, controlling the rotating mechanism 21 arranged in the middle of the intelligent mask to drive the upper half part of the lower section 11 of the intelligent mask connected with the rotating mechanism to rotate and ascend to abut against the lower end of the upper section so as to hide the mouth of the user and control the third air bag group 20 to release the expansion state.
In S7, specifically, after the information analysis module 33 analyzes that the user has eaten food or placed the food at the front end of the mask, the rotation control module 39 controls the upper half portion of the lower section 11 of the smart mask, which is drivingly connected to the rotation mechanism 21 disposed at the middle position of the smart mask, to rotationally ascend and collide with the lower end of the upper section to hide the mouth of the user, and after the rotation of the rotation mechanism 21 is completed, the third airbag module 38 controls the third airbag module 20 to release the inflated state.
Wherein, 11 upper ends in interval are provided with first conflict strips under the intelligence gauze mask, 10 lower extremes in interval are provided with the second conflict strips on the intelligence gauze mask, first conflict strip and second conflict strip are safe silica gel material.
As a preferred mode of the present invention, after S1, the method further includes the steps of:
and S10, analyzing the behavior information of the user in real time according to the external image and analyzing whether the user tears the replacement auxiliary layer 13 of the upper section 10 and the lower section of the intelligent mask in real time according to the behavior information.
Specifically, after the information analysis module 33 analyzes that the user wears the intelligent mask, the behavior analysis module 37 analyzes the behavior information of the user in real time according to the external image, and meanwhile, the information analysis module 33 analyzes whether the user tears the replacement auxiliary layer 13 of the upper section 10 and the lower section of the intelligent mask according to the behavior information in real time.
And S11, if yes, analyzing whether a user pastes a new replacement auxiliary layer 13 to the upper section 10 and the lower section of the intelligent mask in real time according to the behavior information.
Specifically, the information analysis module 33 analyzes that the user will the intelligent mask upper section 10 and the lower section of the replacement auxiliary layer 13 are torn off, and the information analysis module 33 analyzes whether the user has the new replacement auxiliary layer 13 to be pasted on the intelligent mask upper section 10 and the lower section of the intelligent mask in real time according to the behavior information.
And S12, if yes, analyzing whether the transparent section 14 of the replacement auxiliary layer 13 corresponds to the external camera 15 or not in real time according to the external image.
Specifically, information analysis module 33 analysis the user have with new change auxiliary layer 13 paste in between 10 and the lower position of interval on the intelligent gauze mask, information analysis module 33 basis external image real-time analysis changes transparent interval 14 of auxiliary layer 13 and whether have with external camera 15 corresponding, the analysis promptly whether external camera 15 can shoot the outside environment image of intelligent gauze mask through the transparent interval 14 of changing auxiliary layer 13.
And S13, if not, feeding back replacement error information to the user terminal and transmitting the external image to the user terminal in real time.
Specifically, after the information analysis module 33 determines that the transparent section 14 does not correspond to the external camera 15, the information feedback module 40 included in the processing chip 3 feeds back replacement error information to the user terminal to remind the user that the transparent section 14 corresponds to the external camera 15, and meanwhile, the information sending module 41 included in the processing chip 3 transmits the external image to the user terminal in real time so that the user can adjust the position of the replacement auxiliary layer 13; therefore, after the mask is used for a certain time, the service life of the intelligent mask is prolonged by replacing the auxiliary layer 13.
Example two
Referring to fig. 3, fig. 6-7, fig. 9.
This embodiment is substantially identical to the first embodiment, except that, in this embodiment, after S5, the method further includes the following steps:
