Fig. 1 and 2 show that the other using methods and functions of the novel mask are completely consistent with the mask used by the existing atomizer; during the aerosol treatment, the atomizer produces the atomizing liquid that has certain pressure and air, in atomizer face guard body 1 gets into patient's respiratory track together, carries out liquid medicine aerosol treatment to patient's respiratory track. After the 220V ac power supply enters the power supply input terminal of the regulated power supply a1, the regulated power supply a1 outputs a stable dc12V power supply at pins 3 and 4 under the action of its internal circuit, and enters one end of the pressure switch T, the prompt circuit and the power supply input terminal of the time control circuit, so that the above-mentioned circuits and pressure switch are in the power-on working state. During the production of the novel atomization device, a technician adjusts the detection value (such as 130KPA) of the pressure switch T according to the optimal atomization pressure required in clinical medical treatment. When the medical care device is used at the terminal, medical staff firstly count the expiration intervals and the breathing time of a patient (the patient is matched with the statistics, such as 12 breaths per minute, 3 seconds of each inspiration and 3 seconds of expiration), and then adaptively adjust the time of the power output by the 3 and 4 feet of the time-controlled switch A2 (such as 3 seconds of power output every 3 seconds). The patient can start the atomization treatment after wearing the novel atomizer mask body 1 on the face. During actual operation, after getting into the liquid medicine in the intake pipe 101 of atomizer face guard body 1, when liquid medicine pressure is less than the setting value, the inside contact of pressure switch T is closed, relay K1 gets electric actuation its control power input end of actuation and normally open contact end closure, when control switch A2's 3 feet output power like this, solenoid valve DC can get electric inside case open so, what the atomizer output has pressure atomized liquid normally to get into in patient's the respiratory track, patient normally inhales atomized back liquid medicine. After getting into the liquid medicine in the intake pipe 101 of atomizer body 1, when liquid medicine pressure was higher than the setting value, the inside contact of pressure switch T opened a way, like this, even when the 3 feet of control switch A2 were during output power, because the inside contact of pressure switch T opened a way, so solenoid valve DC can not get to its inside case of electricity and close, and the atomizing liquid of atomizer output no longer gets into in patient's the respiratory track temporarily. When the next medicine liquid pressure is lower than the set value, the internal contact of the pressure switch T is closed again, the electromagnetic valve DC is electrified again, and the atomized liquid with pressure output by the atomizer normally enters the respiratory tract of the patient again. Through the aforesaid, this is novel just can keep atomizing treatment time always, guarantees that atomizing back liquid medicine can get into patient's respiratory track under the suitable pressure condition, can reach good atomization effect, can not bring the discomfort for patient as far as possible.

As shown in figures 1 and 2, after the time control circuit works by electrifying, the time control switch outputs power supply (with adjustable time) for 3 seconds every 3 seconds under the action of 3 and 4 feet output power supply time set by medical staff, the power supply enters the control power supply input end of a relay K1 and enters the DC positive power supply input end of the electromagnetic valve through the normally open contact end of a relay K1, thus, when the pressure of the liquid medicine output by the atomizer is appropriate, the electromagnetic valve DC can be electrified for 3 seconds at intervals of 3 seconds in a circulating manner, the valve core is opened for 3 seconds every 3 seconds, so that the respiratory frequency of a patient is approximately consistent, liquid medicine output by the atomizer enters the respiratory tract of the patient when the patient inhales, the atomized liquid medicine entering the mask body is temporarily closed during expiration, and the atomized liquid medicine entering the mask body during expiration is reduced as much as possible, so that the atomized liquid medicine discharged due to expiration is reduced as much as possible correspondingly. Can reduce the waste of atomized liquid as far as possible on the premise of achieving good atomization treatment of respiratory diseases of patients.

As shown in fig. 1 and 2, when the 3-pin output power of the time control switch a2 enters the input end of the control power supply of the relay K1 each time, that is, each time a patient starts to inhale, the high level output by the 3-pin of the time control switch a2 is reduced and limited by the resistor R1 to charge the capacitor C1, within 1 second from the beginning, the capacitor C1 is not fully charged, after the high level power is reduced and limited by the resistors R1 and R2, the base voltage of the high level power entering the NPN triode Q1 is lower than 0.7V, the triode NPN Q1 is cut off, the relay K2 is de-energized, the input end of the control power supply and the normally closed contact end are closed, and the buzzer B sounds to prompt the patient to inhale. When the charging time exceeds 1 second, the capacitor C1 is fully charged, the high level is subjected to voltage reduction and current limitation through the resistors R1 and R2, the voltage of the base electrode of the NPN triode Q1 is higher than 0.7V, the NPN triode Q1 is conducted, the collector outputs the low level and enters the negative power supply input end of the relay K2, the relay K2 is electrified, the control power supply input end and the normally closed contact end of the relay are closed, and then the buzzer B loses power and does not sound any more (when the 3 pins of the time control switch A2 stop outputting the power supply, the charged power of the capacitor C1 can be quickly released, and the normal use cannot be influenced). Through the circuit effect, it is unanimous with patient's frequency of breathing in at every turn, bee calling organ B will be electrified when solenoid valve DC just opens and send suggestion sound (sound is less, and patient can hear under the sound prerequisite, prevents as far as possible that sound is too big to bring the discomfort for patient), and suggestion patient breathes in step, and it is synchronous when breathing in and atomizer output atomizing liquid medicine to guarantee patient like this as far as, reaches good atomization effect. This novel time control circuit and suggestion circuit also can regard as respectively selecting for use, also can be in the time control circuit, set up switch before the suggestion circuit respectively, need not use the time control function to close the power of time control circuit, close the power of suggestion circuit when need not using the prompt facility, open the switch that 3 feet of connecting relay K1 and constant voltage power supply A1 link to each other, solenoid valve DC is in the state of always getting to the electricity, the atomizing liquid medicine in the atomizer will get into the face guard originally internally always. In fig. 2, resistances R1 and R2 are 0.9M and 470K, respectively; the model of the electrolytic capacitor C1 is 1 muF/25V; the model of the NPN triode Q1 is 9013; the buzzer B is an active continuous sound buzzer alarm finished product with the model SF 12V; the time control switch A2 is a finished product of a full-automatic microcomputer time control switch with model KG316T, the microcomputer time control switch is provided with a display screen, seven keys of cancellation/recovery, time correction, week correction, automation/manual operation, timing and clock, and is provided with two power input ends 1, 2 pins and two power output ends 3, 4 pins, a user respectively presses and operates the seven keys (the front ends of the keys are positioned outside the upper front end of the atomizer body, so that medical personnel can conveniently set the power time output by the seven keys 3 and 4 pins), the interval time of the power output by the two power output ends and the time of each power output can be set, and the set power output time can not be changed when power is lost as long as the next operation key setting is not carried out after one time setting; relays K1, K2 model DC 12V.
