Detailed implementation mode

[0042] The following will further describe this application in detail with reference to the Figures 1-4 accompanying drawings.

[0043] An embodiment of this application discloses a plant constant temperature extraction device. Refer to Figure 1 and Figure 2 , the extraction device includes an extraction cylinder 1, an extraction chamber 11 is formed inside the extraction cylinder 1, a liquid inlet pipe 12 is fixedly connected to the top of the extraction cylinder 1, and the liquid inlet pipe 12 is communicated with the extraction chamber 11 for introducing a plant solution into the extraction chamber 11. A liquid outlet pipe 13 is fixedly connected to the bottom of the extraction cylinder 1, and the liquid outlet pipe 13 is communicated with the extraction chamber 11, and the extracted plant solution is discharged through the liquid outlet pipe 13.

[0044] A temperature control component 2 is fixedly installed on the outer wall of the extraction cylinder 1, and the temperature control component 2 includes a temperature sensor and a controller. The temperature sensor is tightly fixed to the outer wall of the extraction cylinder 1 and can accurately detect the temperature inside the extraction chamber 11 in real time. The controller is electrically connected to the temperature sensor and receives the temperature signal transmitted by it.

[0045] A filter membrane 14 is fixedly installed inside the extraction cylinder 1 in the extraction chamber 11. The filter membrane 14 extends horizontally and is located between the liquid inlet pipe 12 and the liquid outlet pipe 13 for filtering solid residues in the plant solution.

[0046] The extraction device further includes an air injection pipe 3. The air injection pipe 3 extends vertically and is located inside the extraction chamber 11. The air injection pipe 3 is located above the filter membrane 14. The bottom of the air injection pipe 3 is closed, the air injection pipe 3 is rotatably connected to the extraction cylinder 1, and the top of the air injection pipe 3 extends and protrudes outside the extraction cylinder 1. An air injection groove is formed inside the air injection pipe 3, and a plurality of air injection holes 31 are evenly spaced on the outer peripheral side of the air injection pipe 3, and the air injection holes 31 are communicated with the air injection groove.

[0047] Refer to Figure 2 and Figure 3, the extraction cylinder 1 is provided with an air delivery member 4. The air delivery member 4 is a hot air delivery pump. In other embodiments, the air delivery member 4 can also be a hot air blower, a blower, etc. The air delivery member 4 is fixedly installed on the top of the extraction cylinder 1. The air delivery member 4 includes an air outlet 41 and an air inlet 42. The air delivery member 4 is fixedly connected with an air delivery pipe 43. The air delivery pipe 43 is communicated with the air outlet 41. The air delivery pipe 43 is rotationally connected and communicated with the spray pipe 3 through a rotary seal.

[0048] See Figure 2 And Figure 4 , a heating box 5 is fixedly installed on the top of the extraction cylinder 1. A heating chamber 51 is formed inside the heating box 5. The heating box 5 is fixedly installed with a heating column 52. The heating column 52 extends along a spiral trajectory and is located inside the heating chamber 51. The heating column 52 is communicated with an external power supply and can heat the air inside the heating chamber 51.

[0049] The heating box 5 is fixedly connected with a connecting pipe 53. One end of the connecting pipe 53 is communicated with the extraction chamber 11, and the other end is communicated with the heating chamber 51. The heating box 5 is fixedly installed with an air inlet pipe 54. One point of the air inlet pipe 54 is communicated with the air inlet 42 of the air delivery member 4, and the other end is communicated with the heating chamber 51. A heat insulation sleeve 8 is fixedly sleeved on the outer peripheral side of the air inlet pipe 54.

[0050] When the air delivery member 4 is started, the air in the extraction chamber 11 enters the air delivery member 4 through the air inlet pipe 54 after passing through the heating chamber 51, and then is transmitted into the spray pipe 3 by the air delivery member 4 through the air delivery pipe 43, and then the air flow is sprayed into the plant solution through the spray holes 31. When the air passes through the heating chamber 51, the heating column 52 heats the air, so that the air sprayed into the plant solution heats the plant solution. An air valve communicated with the extraction chamber 11 is fixedly installed on the extraction cylinder 1, which is used to control the inflow or outflow of air in the extraction chamber 11 and balance the air pressure in the extraction chamber 11.

[0051] The temperature control algorithm is preset inside the controller, which can judge whether the current temperature deviates from the set constant temperature range according to the received temperature wireless signal. Once a temperature deviation is detected, the controller will immediately adjust the heating power of the heating column 52, and quickly adjust the temperature in the extraction chamber 11 back to the set range by increasing or decreasing the heat output. This closed-loop control system can respond to temperature changes in real time, ensure the constancy of temperature during the extraction process, and thus significantly improve the accuracy and stability of extraction. And a heat insulation sleeve 9 is fixedly sleeved on the outer peripheral side wall of the extraction cylinder 1, which can reduce the dissipated heat and improve the heating effect.

[0052] See Figure 2 And Figure 3, the extraction cylinder 1 is provided with a driving assembly 6, and the driving assembly 6 includes a driving motor 61, a driving gear 62 and a connecting gear 63. The driving motor 61 is fixedly installed on the outer wall of the top of the extraction cylinder 1 through its own bracket. The driving gear 62 is fixed on the outer peripheral side of the output shaft of the driving motor 61. The connecting gear 63 is installed and fixed on the outer peripheral side of the air injection pipe 3. The driving gear 62 meshes with the connecting gear 63. When the driving motor 61 is started, the driving gear 62 drives the air injection pipe 3 to rotate through the connecting gear 63, improving the coverage range of the airflow ejected from the air injection holes 31 and enhancing the heating effect.

[0053] A plurality of stirring columns 7 are evenly spaced and fixed on the outer peripheral side of the air injection pipe 3. A transmission groove 71 is formed in the stirring column 7, and the transmission groove 71 communicates with the air injection groove. A plurality of transmission holes 72 are evenly spaced on the outer peripheral side of the stirring column 7, and the transmission holes 72 communicate with the transmission groove 71. During use, the hot air in the air injection groove enters the transmission groove 71 and is ejected from the transmission holes 72. On the one hand, it improves the heating coverage range of the hot air, and on the other hand, it can stir the plant solution through the stirring column 7, reducing the temperature fluctuation of the plant solution.

[0054] The implementation principle of a plant constant temperature extraction device according to an embodiment of the present application is as follows:

[0055] During extraction, the plant solution is introduced into the extraction chamber 11 through the liquid inlet pipe 12. Then, the air delivery member 4 is started. The air in the extraction chamber 11 is heated and sprayed into the plant solution through the air injection holes 31 to heat the plant solution. The extracted solution is located below the filter membrane 14 and is then discharged through the liquid outlet pipe 13.

[0056] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
