When the medical kettle is used, required medicinal materials and a proper amount of water are poured into the kettle body 1 and are uniformly stirred to form a medical liquid, the kettle cover 2 is covered on the kettle body 1, and the medical liquid is heated and kept in a boiling state.
On one hand, after the medicinal materials are boiled in boiling water for a period of time, medicinal materials contacted with the bottom of the pot body 1 are easy to be sticky after being soaked and heated for a long time, namely the medicinal materials are sticky at the bottom of the pot; on the other hand, the properties of some medicinal materials after soaking can be changed, such as swelling and water absorption or floating on the water surface, or the medicinal materials are strip-shaped or curled and can not be completely immersed in water, and the water is continuously evaporated after the liquid medicine is boiled, so that the situation that the medicinal materials can not be fully contacted with the water often occurs, the drug effect of the medicinal materials can not be completely released in the liquid medicine, and the treatment effect of the liquid medicine is influenced.
Therefore, in the boiling process, the medicine liquid needs to be properly stirred to change the position of the medicine materials, so as to avoid the phenomenon of sticking the bottom of the pot and ensure that various medicine materials can be fully contacted with the medicine liquid, the operation can be very simply realized by utilizing the invention, and the specific implementation process is as follows: as the boiling water in the kettle body 1 is continuously evaporated, a large amount of water vapor is gathered at the inner side of the kettle body 1 to increase the pressure in the kettle body 1, at the moment, the handle 27 is rotated to rotate the rotating shaft 3, the crank 7 rotates along with the rotating shaft 3 and drives the piston 8 to slide back and forth through the connecting rod 10, after the piston 8 slides for a certain distance in the direction far away from the rotating shaft 3, the piston 8 is contacted with the push rod 13 and pushes the push rod 13 to move simultaneously, the air inlet stop block 12 connected with the push rod 13 slides in the direction far away from the piston 8 and is separated from the flow baffle 15, the flow baffle 15 relieves the sealing of the through hole 14, and the steam enters the sliding cavity 9 through the.
Along with the increasing of steam entering the sliding cavity 9 and the increasing of steam pressure inside the kettle body 1, when the handle 27 is loosened, the piston 8 is pushed by the steam to slide towards the direction close to the rotating shaft 3, and according to the transmission principle of the crank slider mechanism, the crank 7 rotates under the connection action of the connecting rod 10 and drives the rotating shaft 3 to rotate simultaneously; when the piston 8 slides to the nearest distance from the rotating shaft 3, the push rod 13 is completely separated from the piston 8, the air inlet stop block 12 contacts with the spoiler 15 again under the action of the elastic force of the first spring 16, the air inlet hole 11 is closed, meanwhile, the piston 8 passes through the air outlet hole 17 at the moment, the cavity part filled with steam of the sliding cavity 9 is communicated with the outside through the air outlet hole 17, the steam in the sliding cavity 9 is exhausted through the air outlet hole 17, so that the pressure in the sliding cavity 9 is reduced, at the moment, under the action of the rotational inertia of the crank 7, the crank 7 continues to rotate and drives the piston 8 to slide in the direction far away from the rotating shaft 3 through the connecting rod 10, the air outlet hole 17 is blocked by the piston 8 again, the air in the sliding cavity 9 is compressed by the sliding of the piston 8, so that the pressure in the sliding cavity 9 is increased, and after the piston 8 slides to the farthest distance from the rotating shaft, the steam in the kettle body 1 enters to further increase the pressure in the sliding cavity 9, and the piston 8 slides towards the direction close to the rotating shaft 3 again under the combined action of the rotation inertia of the crank 7 and the steam pressure in the sliding cavity 9; therefore, the piston 8 can realize continuous reciprocating sliding, and the crank 7 drives the rotating shaft 3 to rotate continuously.
When the rotating shaft 3 rotates, the fan blade shaft 5 and the rotating shaft 3 coaxially rotate through the connecting block 4, the friction wheel 19 and the boss 20 generate displacement, and under the action of friction force generated by extrusion contact of the friction wheel 19 and the boss 20, rolling is generated between the friction wheel 19 and the boss 20, so that the fan blade shaft 5 rotates along the axis of the fan blade shaft along with the friction wheel 19 and drives the spiral fan blade 6 to rotate; it can be seen that the helical blades 6 rotate simultaneously: rotation along the axis of the fan blade shaft 5; rotating along the axis of the rotating shaft 3; the medicinal materials in the pot body 1 can be contacted with the spiral fan blade 6 and continuously stirred under the combined action of the two rotating motions so as to ensure that the medicinal materials are not adhered to the bottom of the pot body 1 and are fully contacted with moisture.
When the rotating shaft 3 rotates, the pot cover 2 and the pot body 1 are connected with the clamping groove 26 through the clamping block 25 or in threaded connection, so that the pot cover 2 cannot rotate or displace, and the pot cover 2 and the pot body 1 can still be safely and reliably connected when higher pressure is kept at the inner side of the pot body 1, thereby ensuring the use safety of the electric kettle.
Because the steam pressure is easy to cause danger when being too large, in order to further achieve safe use effect, when the pressure inside the kettle body 1 exceeds a safe value, the steam pressure overcomes the elasticity of the second spring 22 to enable the valve body 21 to slide towards the outside of the kettle cover 2, the pressure relief hole 24 gradually moves out to the outside of the kettle cover 2, the steam is discharged through the blind hole 23 and the pressure relief hole 24, when the steam pressure inside the kettle body 1 is reduced to be below the safe value, the elasticity of the second spring 22 overcomes the steam pressure to enable the valve body 21 to slide towards the inside of the kettle cover 2, and the pressure relief hole 24 is blocked by the kettle cover 2 to enable the air inside and outside the kettle cover 2 not to flow through the blind hole 23 and; in the actual production and use process, the pressure release valve 18 can be selectively used according to the set safe pressure range, so that the inner side of the kettle body 1 can keep a relatively stable and safe high-pressure environment in the use process of the invention, the boiling point of water is increased in the high-pressure environment, and the medicinal materials are easier to be rapidly fused with the water and release effective components in the high-temperature and high-pressure environment, so that the decoction efficiency is obviously improved.
After the medicine is decocted, the valve body 21 is lifted first to release the pressure inside the pot body 1, and then the pot cover 2 is taken down to pour out the medicine.
The steam pressure-driven type Chinese medicine decocting machine is ingenious in structure and simple to operate, the crank-slider mechanism is driven through steam pressure, and the spiral fan blades are driven by the crank-slider mechanism to rotate uninterruptedly, so that a good medicine stirring effect is achieved, traditional Chinese medicine decocting can be completed without human intervention, meanwhile, the medicine is enabled to roll continuously due to the fact that the spiral fan blades continuously stir the medicine, the medicine is guaranteed to be in full contact with moisture, and complete release of medicine components is facilitated; in addition, when the kettle is used, a relatively high pressure value can be kept in the kettle body so as to reach a temperature higher than the boiling point at normal temperature, and the boiling efficiency of traditional Chinese medicines can be greatly improved under the environment of high temperature and high pressure.
The traditional Chinese medicine decocting device is used for decocting traditional Chinese medicines, the kettle cover does not need to be frequently lifted for checking or stirring, so that the labor is saved, and accidental scalding caused by steam when the kettle cover is frequently lifted can be avoided.
