Utilization ratio of drug can be improved.
In one embodiment of the invention, in order to a kind of possible ultrasonic atomizatio implementation is described, so, refer to
Fig. 2, described liquid storage container 101 is provided with supply opening 1011；
Described ultrasonic atomizing device 102 includes: water smoke delivery outlet 1021, vibrations atomizing component 1022, control circuit 1023,
Battery 1024；
Described control circuit 1023 includes construction of switch 10231；
When described vacuum force exceedes predetermined deep breathing force threshold, utilize described vacuum force so that
Described construction of switch 10231 is in closure state；
When described construction of switch 10231 closes, described control circuit 1023 is in connected state, is carried by described battery 1024
The electric energy output of confession is to described vibrations atomizing component 1022；
When described control circuit 1023 connects, control described supply opening 1011 and be in opening；Described liquid storage container 101
The medicinal liquid of middle storage, by the described supply opening 1011 opened, flows through the atomization surface of described vibrations atomizing component 1022；
The electric energy that described battery 1024 provides is converted into ultrasound wave by described vibrations atomizing component 1022, and utilizes described super
The medicinal liquid flowing through described atomization surface is atomized by sound wave；
Medicinal liquid after atomization is through described water smoke delivery outlet 1021 output extremely described nozzle 103.
In an embodiment of the invention, as it is shown on figure 3, described construction of switch 10231 can include a foil
102311, a compression spring 102312 and a metal bar 102313.Wherein, described metal bar 102313 position is fixed, institute
The one end stating compression spring 102312 is connected with described foil 102311, and other end position is fixed.Under normal circumstances, due to
The described compression spring 102312 active force to described foil 102311, described foil 102311 and described metal bar
102313 are separated.
In detail, construction of switch may be located in the space of nozzle interior, or space, construction of switch place and nozzle
Inner space is connected.When user utilizes nozzle to carry out getter action, nozzle interior can be made to form one and to seal cavity, and
Vacuum force is there is in getter action in causing this annular seal space body.
Wherein, when the vacuum force that nozzle internal space does not exist vacuum force or existence is less, be not enough to
The incompressible spring active force to foil, therefore foil can not be made to contact with metal bar.Correspondingly, nozzle interior is worked as
There is vacuum force in space, and when this vacuum force is not less than suction when user deeply breathes, this vacuum force is permissible
The opposing compression spring active force to foil, such that it is able to make foil contact with metal bar.When both contact,
Construction of switch is in closure state, therefore the control circuit at construction of switch place is in connected state.
In detail, when foil contacts with metal bar, compression spring can not to the drawing force of foil
More than vacuum force produced by user's air-breathing.During additionally, user carries out conventional breathing, belong to shallow breathing, Repiration
Do not reach pulmonary；When user deeply breathes, Repiration can reach pulmonary.Therefore, negative pressure produced by user's air-breathing is made
Firmly needing not less than deep breathing force threshold, wherein, active force during user's air-breathing is less than this deep breathing force threshold
Time, Repiration does not reaches pulmonary.
Therefore, in order to Guan Bi construction of switch, so that control circuit connection, the condition that needs meet is: F1≤Fx, and
Fx≥Fmin,
Wherein, F1For the compression spring drawing force to foil, FxSuction function produced by user's air-breathing
Power, FminFor deep breathing force threshold.
During control circuit connection, ultrasonic atomizing device can be triggered, so that it carries out atomization process to medicinal liquid, generate atomization
After medicinal liquid.From the above mentioned, produced by user's air-breathing, vacuum force is not less than deep breathing force threshold, therefore based on
This vacuum force, the medicinal liquid after atomization can be sucked pulmonary, through focus by user.Owing to user's getter action is for deeply breathing
During effect, atomising device could be triggered to be atomized medicinal liquid, therefore atomization medicinal liquid can be fully entrained pulmonary, improve drug utilization
Rate, and avoid carrying out invalid air-breathing during user's medication.
In an embodiment of the invention, the battery that ultrasonic atomizing device includes can be button cell.Control circuit
During connection, by the control circuit of connection, the deposit electricity stored can be exported to shaking atomizing component in battery.
In detail, the atomization surface of vibrations atomizing component can be the atomization surface that ultrasonic transduction activates.Vibrations atomization group
Part can convert electrical energy into ultrasound wave, and when the atomization surface shaking atomizing component exists wavy medicinal liquid thin film, Ke Yitong
Cross the judder amplitude effect of ultrasound wave, medicinal liquid thin film is transformed into the most tiny misty liquid droplets.
In an embodiment of the invention, in order to provide the raw material needed for atomization for vibrations atomizing component, therefore in shake
When dynamic atomizing component is started working, i.e. during control circuit connection, the supply opening on liquid storage container is opened, so that in liquid storage container
The medicinal liquid of the storage supply opening through opening, output is to the atomization surface shaking atomizing component.
Then, based on vacuum force produced by user's air-breathing, can be defeated through water smoke delivery outlet by the medicinal liquid after atomization
Go out to nozzle, and be inhaled into user pulmonary through this nozzle.
Compared with conventional atomizers operation principle, first conventional atomizers manufactures and is quantitatively atomized medicinal liquid, and then user passes through
Repiration to suck pulmonary by the medicinal liquid after atomization, therefore the atomization medicine that the atomization amount of liquid medicine sucking pulmonary no more than previously generates
Liquid measure.It is atomized number of times by manual control, sucks overdose of medicine liquid in user's short time can be avoided, but it cannot be guaranteed that user inhales
The atomization amount of liquid medicine entering pulmonary the most enough treats disease.
Accordingly, in embodiments of the present invention, during user first carries out deep breathing effect, deep breathing effect lasts, atomization
Medicinal liquid persistently produces, and is inhaled by the user pulmonary.
Under normal circumstances, when each user deeply breathes, the persistent period of getter action is the shortest, and duration difference is not
Greatly.Especially in the later stage of getter action, when the produced vacuum force of getter action is not enough to close construction of switch, control electricity
Road will be switched off, thus the supply opening on liquid storage container is closed, and stops feed flow, and vibrations atomizing component quits work, and does not carry out mist
Change processes, therefore user's single medicinal liquid suction volume is the most fixing.But, when certain customers deeply breathe, and the holding of getter action
When the continuous time is longer, getter action produced vacuum force duration of existence, liquid storage container continues feed flow, and vibrations atomizing component is held
Continuous offer is atomized medicinal liquid, therefore this certain customers' single medicinal liquid suction volume is the most.
In view of the above, it will be seen that owing to the deep breathing effect of different user there are differences, therefore different user A Single Intake by Inhalation
The dose of pulmonary may be different.For sucking overdose of medicine liquid in avoiding user's short time, the atomization medicinal liquid controlling user is needed to inhale
Enter amount.In embodiments of the present invention, user is atomized the control mode of medicinal liquid suction volume at least can a following two kinds:
Mode 1: when user deeply breathes each time, the medical liquid atomizing time fixes, and can have fixing in a drug treatment
The suction medicine operation of number of times；
Mode 2: when user deeply breathes each time, the medical liquid atomizing time is not fixed, but the medication in a drug treatment is total
Amount is fixing.
In detail, for aforesaid way 1:
In one embodiment of the invention, described ultrasonic atomizing device 102 also includes: timer 1025；
Described timer 1025 records timing duration when described control circuit 1023 is in connected state；Institute when record
State timing duration when reaching duration threshold value set in advance, control described supply opening 1011 and be closed；
When described control circuit 1023 is in non-connected state, the described timing duration of record resets.
In detail, during control circuit connection, supply opening starts to provide medicinal liquid, vibrations atomizing component to start to be atomized medicinal liquid, meter
Time device start timing.Before control circuit does not disconnects, if the timing duration of timer record reaches corresponding duration threshold value, permissible
Control supply opening to close, stop feed flow.
Preferably, duration threshold value can be set and be not more than the single deep breathing effect lasts duration of domestic consumer, to ensure
User's single dosage is enough.Then, in a drug treatment, it is fixed the deep breathing effect of number of times by manual control,
To complete the medication operation in one drug treatment of user.
In detail, the determination mode of above-mentioned duration threshold value can be accomplished in that
In one embodiment of the invention, described duration threshold value can be determined according to formula t=V/ υ and V=v × n,
Wherein,
Described t is described duration threshold value, and V is the permission dosage in a drug treatment, and υ is that medicinal liquid passes through described feed flow
The volume flow rate of mouth 1011, v is that single allows dosage, and in n is a drug treatment, described single allows dosage corresponding
Can times for spraying.
Permission dosage due in a drug treatment: V fixes, therefore can be according in the drug treatment arranged
Can times for spraying: n, calculate single allow dosage: v.Additionally, due to medicinal liquid can be consolidated by the volume flow rate of supply opening
Fixed: υ, therefore duration threshold value: t can be calculated.
Preferably, by adjusting n, and/or, the value of υ, duration threshold value: t can be made to be not more than the single of domestic consumer deep
Repiration duration.
In detail, for aforesaid way 2:
In one embodiment of the invention, described ultrasonic atomizing device 102 also includes: timer 1025；
In the range of present timing, described timer 1025 records tiring out when described control circuit 1023 is in connected state
Timing is long；When the described accumulative duration of record reaches duration threshold value set in advance, control described supply opening 1011 and be in pass
Closed state；
When described present timing scope lost efficacy, the described accumulative duration of record resets；
Wherein, the duration that lasts of a timing range is not less than a drug treatment.
In detail, during control circuit connection, supply opening starts to provide medicinal liquid, vibrations atomizing component to start to be atomized medicinal liquid, meter
Time device start timing.Before control circuit does not disconnects, if timer is in the range of present timing, the accumulative duration of record reaches right
During the duration threshold value answered, supply opening can be controlled and close, stop feed flow.
For example, if a drug treatment is 6h, then the duration that lasts of each timing range of timer can not
Less than 6h.As in the present embodiment, a length of 6h when lasting of each timing range can be set.Furthermore, it is possible to arrange above-mentioned
Duration threshold value is 10.0s.
Assuming that user inhales for the first time the medicine time is 9:00 on the same day, then first timing range can be the same day 9:00～
15:00.When 15:00 on the same day, first timing range lost efficacy, and in this timing range, the accumulative duration of record resets.Work as user
In time again carrying out inhaling medicine after 15:00 the same day, the time of medicine can be inhaled with this time, determine next timing range.
For first timing range, if user once inhales medicine when 9:00 on the same day, a length of 4.5s when inhaling medicine,
Therefore add up duration and be similarly 4.5s；If user inhales medicine when 9:02 on the same day again, a length of 4.0s when inhaling medicine, therefore accumulative duration
For 8.5s, i.e. 4.5s+4.0s=8.5s；If user inhales medicine when 9:05 on the same day again, when inhaling medicine up to 1.5s, i.e. count
Time device record accumulative time when the 10.0s, supply opening can be closed, stop feed flow.And before same day 15:00, Yong Huzai
When medicine is inhaled in secondary trial, this supply opening can be not turned on.
In detail, the determination mode of above-mentioned duration threshold value can be accomplished in that
In one embodiment of the invention, according to formula t=V/ υ, determine described duration threshold value, wherein,
Described t is described duration threshold value, and V is the permission dosage in a drug treatment, and υ is that medicinal liquid passes through described feed flow
The volume flow rate of mouth 1011.
In the embodiment of the present invention, the permission dosage due in a drug treatment: V fixes, therefore can lead to according to medicinal liquid
Cross the volume flow rate of supply opening: υ, calculate duration threshold value: t.
As shown in the above, timing effect based on timer, can accurately control user in a drug treatment
Always inhale dose.This implementation sucks overdose of medicine liquid in can avoiding user's short time, and can ensure that user inhales
The atomization amount of liquid medicine entering pulmonary can reach sanatory institute expense.
In detail, owing to the amount of liquid medicine of liquid storage container storage inside is limited, inhale persistently increasing of medicine number of times so that with user,
Amount of liquid medicine in liquid storage container persistently reduces.
Along with the lasting minimizing of liquid storage container inner liquid medicine amount, in order to ensure that the medicinal liquid flow velocity at supply opening is fixed, so that medicine
Liquid mist stable operation performs, therefore in one embodiment of the invention, refer to Fig. 3, and described liquid storage container 101 includes: supply

One end position of described compression spring 1013 is fixed, and the other end is connected with described liquid storage cavity 1012；
In described liquid storage cavity 1012, the medicinal liquid of storage is by described supply opening 1011 output extremely described ultrasonic atomizing device
When 102, the compress variation of described compression spring 1013 reduces, and the capacity of described liquid storage cavity 1012 reduces, so that medicinal liquid is even
Speed output,
Wherein, △ V=S × △ L, △ V are the capacity reduction amount of described liquid storage cavity 1012, and S is described liquid storage cavity
1012 along the sectional area size of described compression spring 1013 axis, and △ L is the fall of the compress variation of described compression spring 1013
Low value.
In an embodiment of the invention, the wall body of the liquid storage cavity being connected with supply opening can be taper or arc.This
One implementation can be so that the medicinal liquid in liquid storage cylinder body flow to supply opening.
In an embodiment of the invention, the wall body of the liquid storage cavity being connected with compression spring can be cylindrical.This
