It is multiple and with slider-crank mechanism correspond;Multiple slider-crank mechanisms move at the same time can effectively eliminate slider-crank mechanism
Movement dead.
The present invention is mixed into liquid in use, required medicinal material and suitable water are poured into kettle body 1 to stir evenly, by pot
Lid 2 is covered above kettle body 1, is heated liquid and liquid is maintained at fluidized state.
On the one hand, after boiling water infusion after a while, soaked with the medicinal material that the bottom of kettle body 1 contacts for a long time
With being also easy to produce viscous glutinous i.e. " the viscous the bottom of a pan " phenomenon after heating;On the other hand, some medicinal materials after immersion its character can produce and change
Become such as expansion water suction or swim on the water surface, or some medicinal materials shapes itself for strip or it is curly can not submerge completely in water,
In addition continuous evaporation water point is also wanted after liquid boils, thus the situation that medicinal material cannot come into full contact with moisture often occurs, is made
The drug effect of medicinal material cannot be completely released in liquid, influence the therapeutic effect of liquid.
Therefore, convert medicinal material generation position, it is necessary to carry out appropriate agitation to liquid during boiling, to avoid viscous pot
Bottom phenomenon simultaneously ensures that various medicinal materials can come into full contact with liquid, and can easily realize very much this behaviour using the present invention
Make, its specific implementation process is:As the boiling water in kettle body 1 constantly evaporates, substantial amounts of vapor is assembled in the inner side of kettle body 1 makes pot
Pressure rise in body 1, at this time, rotational handle 27 make slider-crank mechanism cross dead-centre position, when steam pressure overcomes first
After the elastic force of spring 13, by Steam Actuation and to being slided close to the direction of piston 8, air admission hole 11 is opened inlet valve 12, steam
Enter through air admission hole 11 in sliding cavity 9.
As the steam entered in sliding cavity 9 is continuously increased, and the continuous increase of 1 inner side steam pressure of kettle body, work as pine
After opening handle 27, piston 8 close to the direction of shaft 3 by Steam Actuation and to sliding, according to the transmission principle of slider-crank mechanism,
Crank 7 produces under the connection function of connecting rod 10 to be rotated and drives shaft 3 while rotate, meanwhile, edge cam 17 is in synchronous biography
Rotated synchronously under the action of dynamic device with shaft 3, during being slided in the direction of piston 8 to close shaft 3, edge cam 17
The flat segments of cam part contacted with exhaust valve 15, thus exhaust valve 15 does not produce slip.
When piston 8 slides into the minimum distance with shaft 3, the raised section of the cam part of edge cam 17 gradually with exhaust
Door 15 contacts, and exhaust valve 15 produces downward sliding, and exhausting-gas hole 14 is opened, and the steam in sliding cavity 9 is via 14 row of exhausting-gas hole
The pressure sent as an envoy in sliding cavity 9 reduces;At this time under the rotator inertia effect of crank 7, crank 7 is rotated further and 10 band of through connecting rod
Piston 8 is slided to the direction away from shaft 3, and in the process, exhaust valve 15 is convex with the cam part of edge cam 17 all the time
Section contact is played, exhausting-gas hole 14 is in open mode, and the steam in sliding cavity 9 is compressed and discharged rapidly through exhausting-gas hole 14 by piston 8,
After piston 8 slides into the maximum distance with shaft 3, flat segments of the exhaust valve 15 again with the cam part of edge cam 17 connect
Touch, the upward sliding under the elastic force effect of second spring 16 of exhaust valve 15 closes exhausting-gas hole 14, and the steam of the inner side of kettle body 1 is continuous
Entering through air admission hole 11 in sliding cavity 9 makes the pressure in sliding cavity 9 raise again, in the rotator inertia and sliding cavity 9 of crank 7
Steam pressure collective effect under, piston 8 again to close to shaft 3 direction slide;Thus, it is possible to piston 8 is set to realize not
Discontinuously reciprocatingly slide, so that crank 7 drives shaft 3 constantly to rotate.
When shaft 3 rotates, flabellum axle 5 rotates coaxially through contiguous block 4 with shaft 3 and friction pulley 21 is produced position with boss 22
Move, in the case where friction pulley 21 contacts the frictional force effect produced with the extruding of boss 22, rolling is produced between friction pulley 21 and boss 22
Dynamic, therefore, flabellum axle 5 produces the rotation along own axes with friction pulley 21 and drives spiral fan 6 to produce rotation;Thus may be used
Know, spiral fan 6 does rotated below at the same time:1. the rotation of the axis along flabellum axle 5;2. the rotation of the axis along shaft 3;Rotate
1. so that constantly being stirred stirring with the medicinal material that spiral fan 6 contacts, rotate and 2. the position of spiral fan 6 constantly changed,
Two kinds of rotational motion collective effects make the medicinal material in kettle body 1 to contact with spiral fan 6 and constantly be stirred, to ensure medicine
Material with moisture with the bottom adhesion of kettle body 1 and not coming into full contact with.
When shaft 3 rotates, due to being connected between pot lid 2 and kettle body 1 through fixture block 25 with card slot 26 or by being threadedly coupled,
Therefore pot lid 2 itself will not produce rotation or displacement, and pot lid 2 still may be used with kettle body 1 when the inner side of kettle body 1 keeps higher pressure
Reliably and securely connect, ensure that the present invention's is safe to use.
During being reciprocatingly slided each time due to piston 8, exhausting-gas hole 14 can be opened once, therefore the steaming of the inner side of kettle body 1
Vapour is intermittently discharged to outside, so that ensure that the steam pressure in kettle body 1 is maintained in metastable pressure limit,
Avoid the security risk that hypertonia is brought;In actual use, relatively stable, the safe hyperbaric environment in the inner side of kettle body 1
Can raise the boiling point of water, and in the environment of high temperature and pressure, medicinal material is more easy to quickly be integrated with water and discharge active ingredient, makes
Efficiency must be boiled to significantly improve.
After the completion of medicinal material boils, first pressure release valve 19 is lifted make the steam of the inner side of kettle body 1 through relief hole 18 discharge from
And pressure is discharged, liquid can be poured out by then removing pot lid 2.
Clever structure of the present invention, it is easy to operate, slider-crank mechanism is driven by steam pressure, then through slider-crank mechanism
Spiral fan is driven uninterruptedly to rotate, and then good medicinal material stirring effect, effectively prevent the viscous the bottom of a pan phenomenon from occurring, and not
Human intervention is needed to complete Traditional medicine infusion, meanwhile, continuous agitation of the spiral fan to medicinal material causes medicinal material constantly to roll, and protects
Coming into full contact with for medicinal material and moisture is demonstrate,proved, beneficial to the complete release of drug ingedient;In addition, the present invention can make to protect in kettle body when using
Metastable higher pressure force value is held to reach the boiling temperature being higher than under room temperature, Chinese medicine can be greatly improved in the environment of high temperature and pressure
The efficiency boiled.
Traditional medicine infusion is carried out using the present invention, it is not necessary to is continually raised pot lid and is checked or stirred, not only saves people
Power, the accidental scalding that steam zone comes when also can avoid frequently raising pot lid.
