Change to be arranged with outside core and adjusts inlet opening opening or closed buoy using buoyancy.The atomization tank, atomizer lid, jet pipe with
And atomization core is existing structure, atomization tank is a cylindric and closed container in bottom, for storing medical fluid.According to " literary mound
In " principle, the oxygen with pressure passes through jet pipe and the tiny nozzle of atomization core forms high-speed flow, generates negative pressure, drives medicine
Liquid is ejected into obstacle i.e. atomizer together and covers, and splashing under high-speed impact around makes drop become misty particle.It is described
The liquid inlet port other end, which passes to outside atomization tank, to be referred to, the container of external storage medical fluid can by liquid inlet port by medical fluid be added into
Enter inside atomization tank.Medical fluid can by by container be placed on the mode above atomization tank take the mode of infusion automatically into
Atomization tank, without the power sources such as additional pump are increased, to reduce the closure pressure of buoy.The buoy is set in outside atomization core
Refer to, buoy can be slided up and down with respect to atomization core, i.e., have gap between buoy and atomization core.The closing inlet opening floats
Drift refers to, when liquid volume is more, floats buoy closing inlet opening, and when liquid volume is few, under the effect of gravity, buoy decline is opened
Inlet opening, medical fluid enter atomization pot bottom by the gap between buoy and atomization core and the gap between buoy and atomization tank.
The buoy, which can be, blocks inlet opening by plane, is also possible to other plugging structures in the prior art and blocks inlet opening.
It is worth noting that the buoy refers to the buoy made of material of the density lower than water.Since medical fluid density is usually bigger than water,
Therefore, buoy can float on medical fluid.To reduce the resistance for hindering buoy to float, one or more can be opened up in the end face of buoy
A loss of weight blind hole.
Preferably, the buoy corresponds to the taper for being equipped at inlet opening and extending to inlet opening and blocks；The top that taper blocks
Go deep into the diameter that the maximum gauge that in inlet opening and taper blocks is greater than inlet opening lower end.Since taper being capable of adaptive inlet opening
Diameter, therefore taper blocks can shut the opening of inlet opening, after reducing buoy closing inlet opening, liquid leakage.It is described into
Fluid apertures lower end refers to one end closest to buoy.The top that taper blocks is goed deep into inlet opening referring to few and without medicine in liquid volume
When liquid measure, taper block still some in inlet opening, thus prevent buoy around atomization core rotate, make taper block with into
Fluid apertures dislocation.Also to pass through other prior art manners, such as keep jet pipe eccentric with respect to atomization tank or section of atomization core certainly
Face is non-circular shape, and can also realize prevents buoy from rotating around atomization core.Since the maximum gauge that taper blocks is greater than under inlet opening
The diameter at end, therefore can guarantee that taper closure can close inlet opening.The taper closure, which can be, is integrated knot with buoy
Structure is also possible to separate structure, realizes that taper is blocked by modes such as bondings and is fixedly connected with buoy.The cone angle that taper blocks
It should not be too large, prevent taper from blocking and shake big, when closure, leakage is big, and cone angle is generally 15 degree to 45 degree.The cone angle refers to cone
Shape blocks the bevel edge of longitudinal section and the angle of axis.
Preferably, the inlet opening is in up-small and down-big taper.The inlet opening of taper makes inlet opening block phase with taper
Match, reduces the range of buoy rotational angle.The taper that the taper of inlet opening can be less than, block more than or equal to taper.But
Be inlet opening cone angle be less than, the amount of cone angle that blocks greater than taper should not be too large, prevent from leaking, the cone angle and taper of inlet opening
The cone angle and difference of closure are generally 2 degree to 5 degree.
Preferably, the taper that the taper blocks is equal to the taper of inlet opening.When the taper that taper blocks is equal to inlet opening
Taper when, the contact surface that inlet opening and taper block is maximum, bigger to the resistance of medical fluid, therefore anti-leak result is relative to cone
The taper that shape blocks will be got well when being not equal to the taper of inlet opening.
Preferably, the atomization core is outward extended with the step for holding buoy.Since the inside bottom of general atomization tank is
Up big and down small funnelform cone cell, the diameter of buoy are greater than the minimum diameter of bottom, and setting step is held buoy, can be prevented
In the case where not having medical fluid or liquid volume to lack, buoy is stuck in bottom middle section, causes medical fluid that can not flow into buoy lower section or medical fluid
Flow velocity is slow, is deposited in big medicine amount liquid above buoy, causes medical fluid to flow directly out atomizer, cause danger.
Preferably, the taper blocks lower end surface and offers loss of weight blind hole.Since taper closure increases the quality of buoy,
The gravity for increasing buoy slows down buoy reaction speed, and loss of weight blind hole is arranged, can be improved buoy reaction speed, while loss of weight is blind
Hole reduces the amount of unbalance of buoy, makes the center of gravity of buoy close to the buoy center of circle, prevents buoy from blocking atomization core, to cannot seal
Close inlet opening.
