Cover.
Background technology
In the environment of human lives' work, various pollutants serious threat the quality of air, also directly threatens people
The health of class.Therefore need to wear mouth mask in many occasion people, but existing self-inhalation filter respirator is deposited in use
In many deficiencies:On the one hand, this mouth mask can allow user to feel expiratory dyspnea.Because the sealing of mouth mask is strong, user
Overcome mouth mask to breathe extraneous air to the resistance of air, expiratory dyspnea will be felt or even felt suffocated, particularly in user
During in high labor intensity, physiological metabolism level is higher, and respiratory capacity increases rapidly, and now the comfortableness of mouth mask is just more difficult to protect
Card;On the other hand, because the sealing of mouth mask is strong, the sound of user is difficult to pass to the external world, the communication between user
Become difficult.Therefore research and development can meet human safety and comfortableness and the dustproof mask without communication disorders simultaneously,
Health for protecting labourer in high dust atmosphere, has important practical significance.
In view of the above-mentioned problems, people start to develop with communication function, the intelligent mouth mask of automatic ventilation function.Application No.
201310144689.0 Chinese invention patent, discloses a kind of automatic mouth mask, and the mouth mask includes mask body and is connected to

Embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
A kind of multifunctional intellectual mouth mask, its structure as shown in Figure 1, 2, the mask body 1 and wear by including mask body 1
The cavity of sealing is formed between the face of wearer, the mask body 1 is provided with communication device 9, controller 5 and passes through connection
The sensor assembly 4 and battery 7 that line is connected with the controller 5, are additionally provided with intake valve 2 and air outlet valve 3, on the intake valve 2
Provided with the blower fan 6 being connected by connecting line with the controller 5.The mouth mask also include one independently of outside mask body 1,
For entering the wireless receiver 8 of row data communication with the controller 5.
The controller 5 includes central processing unit 51 and the wireless transmitter module 52 being attached thereto;The central processing unit
The signal that 51 pairs of sensor assemblies 4 input carries out signal-data processing, and output control signal controls the blower fan 6 and nothing
Line transmitter module 52 works;The wireless transmitter module 52 is used to realize between the controller 5 and the wireless receiver 8
Data communicate.
The sensor assembly 4 includes:For detect in air pressure in cavity or detection cavity with the gas outside mask body 1
The pressure sensor 41 of pressure difference;For detecting the humidity sensor 42 in cavity with 1 outer humidity of mask body;For detecting cavity
The air flow sensor 43 of interior air mass flow;For detecting the respiratory frequen 44 of wearer's respiratory rate.
The voltage signal for the reflection air pressure size that the controller 5 is exported by the pressure sensor 41 and setting
Threshold value size control blower fan 6 unlatching, stopping and rotating speed.When the pressure sensor 41 is used to detect the air pressure in cavity
When, the threshold value is 1 standard atmospheric pressure.When the atmospheric pressure value in cavity is less than 1 standard atmospheric pressure, inside mask body 1
Atmospheric density it is relatively low, compared with normal condition, oxygen content is less, wearer need improve inspiratory capacity could meet body pair
The demand of oxygen.At this moment, the controller 5 starts blower fan 6.Air pressure in cavity is lower, and the rotating speed of the blower fan 6 is bigger, makes
Air pressure in cavity is rapidly achieved 1 standard atmospheric pressure, to reach the breathing needs of human normal;When the air pressure in cavity reaches
During 1 standard atmospheric pressure, the controller 5 controls blower fan 6 to stop.When the pressure sensor is used to detect hollow cavity interiors and mouth
During draught head outside cover body 1, the threshold value is 0.
The voltage signal for the reflection temperature level that the controller 5 is exported by the humidity sensor 42 and setting
Threshold value size control blower fan 6 unlatching, stopping and rotating speed.The humidity threshold that the present embodiment is set is 50%.When humidity passes
When the humidity in cavity that sensor 42 detects is identical with the humidity outside mask body 1, the controller 5 controls blower fan 6 to stop;
When the humidity in cavity is different from outside mask body 1 humidity, and the humidity outside mask body 1 is more than 50%, wet in cavity
When degree is less than 50%, the controller 5 controls blower fan 6 to start;When the humidity in cavity is different from the humidity outside mask body 1,
And the humidity outside mask body 1, less than 50%, when the humidity in cavity is more than 50%, the controller 5 also controls blower fan 6 to open
It is dynamic;The difference of humidity and the humidity outside mask body 1 in cavity is bigger, and the rotating speed of the blower fan 6 is bigger.Air outlet valve 3 limits
The rise of pressure value in cavity.
The mask body 1 also includes the air filtration layer for being arranged on the outside of intake valve 2.Air filtration layer is set
Purpose is for crossing the pernicious gas in air filtering.
The controller 5 determines operating voltage of the blower fan 6 between breathing twice according to the output of pressure sensor 41, when
The voltage judges the air filtration layer failure when exceeding the threshold value of setting, by prompting equipment to remind wearer more to ventilate
Filter layer, the prompting equipment are the wireless receiver 8 or are arranged on the indicator lamp being connected in mask body 1 with controller 5.
The operating voltage (driving voltage) of blower fan 6 is provided by controller 5, and therefore, controller 5 directly obtains the operating voltage
Size., can be with according to operating voltage of the blower fan 6 between breathing twice significantly lower than the operating voltage of eupnea this feature
Obtain operating voltage of the blower fan 6 between breathing twice.Because with the growth of usage time, the cleannes of air filtration layer are not
It is disconnected to decline, operating voltage of the blower fan 6 between breathing twice is constantly raised, illustrate air mistake when being increased to the threshold value of setting
Filtering layer has failed.The different threshold values of air filtration layer are also different, and the threshold value is determined by experiment.
Indicator lamp being connected with the controller 5, that prompting cell voltage is too low is set in the mask body 1.By institute
State the light on and off that controller 5 controls indicator lamp according to the size output control signal of cell voltage.
The wireless receiver 8 includes image display 81, sound module 82 and signal receiving module 83.The signal
Receiving module 83 receives the data-signal that the controller 5 is sent and handled, and is then sent to described image display module 81
And/or sound module 82, carry out data and show and/or pronounce prompting.
Preferably, the controller 5 is by controlling blower fan 6 to make to keep slight positive pressure state in mask body.Even if sealing is not
Sternly, outside air can not stimulate the menstrual flow poorly sealed place into cavity.
The communication device 9 includes loudspeaker 91, microphone 92, blue tooth wireless communication module and Sound Processor Unit 94.Institute
Microphone 92 is stated to be converted into electric signal by the sound of people and deliver to the Sound Processor Unit 94 to be handled, it is wireless by the bluetooth
Communication module 93 is launched after the output signal of the Sound Processor Unit 94 is transformed into radiofrequency signal;The bluetooth channel radio
The radiofrequency signal received is delivered to the Sound Processor Unit 94 and handled by news module 93, and the Sound Processor Unit 94 will export
Audio signal deliver to loudspeaker 91.
Preferably, the blue tooth wireless communication module 93 can carry out bluetooth connection with mobile phone, receive the Voice Navigation of mobile phone,
Realize that mobile phone is linked up.
The invention is not restricted to above-mentioned embodiment, made any to above-mentioned embodiment aobvious of those skilled in the art and
The improvement or change being clear to, all without the design beyond the present invention and the protection domain of appended claims.
