[0031] In the first specific embodiment, the traditional Chinese medicine extraction tank with the pressure monitoring control device comprises a decocting mechanism 100 and a pressure control mechanism 200 installed on the decocting mechanism 100. The decocting mechanism 100 is used for boiling the traditional Chinese medicine liquid and continuously generating medicine mist steam, and the pressure control mechanism 200 is used for monitoring and balancing the pressure of the medicine mist in the decocting mechanism 100.

[0036] The inside of the fixed plate 210 is fixedly provided with a transversely arranged pressure relief cabin 220. The outer end of the pressure relief cabin 220 is provided with a cover 2201. The outside of the pressure relief cabin 220 is fixedly provided with a return pipe 2502, and the other end of the return pipe 2502 is communicated with the inner cavity of the steam output pipe 150.

[0037] When the traditional Chinese medicinal materials and water are transferred to the extraction tank 110 and the inner cavity of the heat-insulating inner tube 160, as the medicinal liquid in the extraction tank 110 is boiled, the generated medicinal mist steam is continuously transferred to the upper half of the inner cavity of the extraction tank 110, and the medicinal mist steam is directly output along the steam output pipe 150 within the controllable pressure bearing range of the external cold shower device. When the pressure of the external cold shower device is overloaded, the air pressure detector 140 monitors the air pressure in the inner cavity of the extraction tank 110 in real time, and the monitored real-time pressure is transmitted to the control module 250 through the air pressure detector 140. When the pressure exceeds the preset value, the control module 250 controls the sub-rod in the telescopic driving part 230 to extend outward, and finally the high-pressure medicinal mist steam in the inner cavity of the extraction tank 110 is transferred to the interlayer along the through hole of the pressure-resistant shell 170, and is input into and temporarily stored in the pressure relief cabin 220 and the inner cavity of the cover 2201 along the output hole 1101.

[0038] When the pressure in the external cold shower device and the pressure in the inner cavity of the extraction tank 110 are in a balanced state, the control module 250 controls the sub-rod in the telescopic driving part 230 to reset and retract, and finally the piston 2202 extrudes the medicinal mist steam in the inner cavity of the pressure relief cabin 220, and the steam medicinal mist is returned to the steam output pipe 150 along the return pipe 2502.

[0039] Please refer to Figures 3 to 5 On the basis of the above scheme, three feeding ports 1102 can be arranged on the outer wall of the extraction tank 110, the output hole 1101 can be arranged on the outer wall of the extraction tank 110, and the first lead screw 1201 and the second lead screw 1301 can be threadedly installed at the top end of the extraction tank 110.

[0040] The extraction tank 110 and the pressure-resistant shell 170 are arranged with an interlayer, and the output hole 1101 is communicated with the interlayer.

[0041] The bottom end of the steam output pipe 150 penetrates into the inside of the sealing cover 120, and the pipe segment of the air pressure detector 140 is adapted to penetrate into the sealing cover 120.

[0042] The top of the inner cavity of the extraction tank 110 can also be provided with a cylindrical groove, and the sealing cover 120 is movably installed in the cylindrical groove. By rotating the first lead screw 1201 to drive the sealing cover 120 to be lifted upward along the cylindrical groove, the three feeding ports 1102 are communicated with the environment in the extraction tank 110, and then the traditional Chinese medicinal materials and water are input into the inner cavity of the extraction tank 110 and the heat-insulating inner tube 160 along the three feeding ports 1102.

[0043] The gap between the built-in ring pad 130 and the inclined surface of the pressure-resistant shell 170 is controlled by the second lead screw 1301, and when the gap between the built-in ring pad 130 and the inclined surface of the pressure-resistant shell 170 gradually increases, the pressure relief amount of the drug mist vapor increases, and when the gap between the built-in ring pad 130 and the inclined surface of the pressure-resistant shell 170 gradually decreases, the pressure relief amount of the drug mist vapor decreases.

[0044] Please refer to Figure 3 and Figure 6 The top of the fixed plate 210 can also be fixedly installed with four symmetrically distributed threaded studs 2101, and the outer threads of the threaded studs 2101 are installed with nuts for fixing the control module 250.

[0045] The bottom of the pressure relief cabin 220 is fixedly installed with two groups of clamping plates 2203, the inside of the two groups of clamping plates 2203 is installed with telescopic driving members 230, the telescopic driving members 230 are installed with linkage plates 240, the pressure relief cabin 220 and the cover 2201 are movably installed with pistons 2202, and the other end of the linkage plate 240 is installed on the outer end of the piston 2202.

[0046] The cover 2201 is inserted into the pipe segment inside the pressure relief cabin 220 and is sleeved with a sealing ring, and the plug of the piston 2202 penetrating into the inner cavity of the pressure relief cabin 220 is sleeved with a sealing ring.

[0047] The fixed plate 210 is fixed on the outer wall of the extraction tank 110 by welding, the control module 250 is controlled by the cloud through wireless communication, the telescopic driving member 230 is electrically connected with the control module 250, when the gas pressure detector 140 monitors the gas pressure in the inner cavity of the extraction tank 110 in real time and transmits the monitored data to the control module 250, the start and stop of the telescopic driving member 230 are automatically controlled by the preset value set by the cloud, so that the gas pressure in the inner cavity of the extraction tank 110 can be quickly balanced.

[0048] The working principle and use process of the utility model are as follows:

[0049] With the continuous descent of the second lead screw 1301, the built-in ring pad 130 movably installed at the bottom end of the second lead screw 1301 is pressed and adheres to the inclined surface at the top end of the pressure-resistant shell 170, then the first lead screw 1201 is rotated, the sealing cover 120 is lifted upward by the first lead screw 1201, and three feeding ports 1102 are exposed.

[0050] Then the traditional Chinese medicinal materials are put into the cavity formed by the extraction tank 110 and the heat-insulating inner tube 160 through the three feeding ports 1102, then water is added into the inner cavity of the extraction tank 110, then the sealing cover 120 is reset, and the built-in ring pad 130 is lifted upward.

[0051] With the medicine liquid in the extraction tank 110 being boiled and generating medicine mist steam, the medicine mist steam is input into the external cold flow device through the steam output pipe 150, and is liquefied and stored by condensation. Once the pressure of the output medicine mist steam is too large, the real-time detection of the medicine mist pressure is performed by the air pressure detector 140, the monitoring and instruction are performed by the control module 250, and then the telescopic driving part 230 is in the standby operation state. Then the inner sub-rod of the telescopic driving part 230 is extended outward and pushes the linkage plate 240 and the piston 2202 to extend outward, the plug 1702 is contracted under pressure, the medicine mist steam is transmitted to the inner cavity of the pressure relief cabin 220 along the through hole inside the pressure-resistant shell 170, the pressure in the inner cavity of the extraction tank 110 is monitored and regulated by the temporary pressure relief mode, and the pressure in the inner cavity of the extraction tank 110 is balanced. When the pressure of the external cold shower device is relieved and the cooling operation can continue, the telescopic driving part 230 is controlled by the control module 250 again, until the inner sub-rod of the telescopic driving part 230 is reset, the piston 2202 extrudes the medicine mist steam in the inner cavity of the pressure relief cabin 220, and finally the medicine mist steam is input into the steam output pipe 150 along the reflux pipe 2502.
