When the condenser cooler 5 needs to be disassembled, it is convenient to take out the return water pipe 12 connected to the condenser cooler 5 from the return water tank 11; when too much liquid condenses in the condenser cooler 5, it is discharged into the return water tank 11 through the return water pipe 12, and then flows back to the heating cavity 15 through the connecting pipe 10; the device heats the liquid in the distillation barrel 1 to a specified temperature, converts it from liquid to gas, and then enters the condenser cooler 5 through the distillation tube 9, and is converted into liquid by condensation in the condenser cooler 5, and then the liquid is retained in the collection barrel 14 from the outlet pipe 4, and finally the required liquid is obtained.

[0026] In this embodiment, the distillation barrel 1 and the pot cover 2 are connected by a buckle. The detachable connection between the distillation barrel 1 and the pot cover 2 is convenient for the maintenance and cleaning of the heating cavity 15, and a sealing ring is provided between the distillation barrel 1 and the pot cover 2, which can effectively improve the sealing between the distillation barrel 1 and the pot cover 2 and prevent gas escape.

[0027] In this embodiment, a one-way valve 17 is provided on the connecting pipe 10, and the water outlet of the one-way valve 17 is toward the distillation barrel 1. The one-way valve 17 only allows the liquid in the condensation cooler 5 to flow toward the heating chamber 2, thereby preventing the water vapor distilled in the heating chamber 2 from entering the return water tank 11 through the connecting pipe 10, and then flowing into the air through the gap between the baffle 18 and the return water pipe 12.

[0028] In this embodiment, a baffle 18 is sleeved on the return water pipe 12, the bottom of the baffle 18 is in contact with the return water groove 11, the baffle 18 is in a circular ring shape, and the inner diameter of the baffle 18 is adapted to the diameter of the return water pipe 12, and there is a gap between the inner circle of the baffle 18 and the outer wall of the return water pipe 12, which facilitates the flow of liquid in the return water pipe 12 and the return water groove 11; the outer diameter of the baffle 18 is larger than the diameter of the return water groove 11; the baffle 18 is arranged on the top of the return water groove 11 to prevent air impurities and dust from entering the heating cavity 2 or the condensation cooler 5 from the return water groove 11, resulting in reduced detection accuracy.

[0029] In this embodiment, a sealing gasket 19 is provided at the bottom of the baffle 18, and the sealing gasket 19 is a silicone gasket that is resistant to high temperatures; the diameter of the sealing gasket 19 gradually decreases from the end close to the baffle 18 to the end away from the baffle 18, and the maximum diameter of the sealing gasket 19 is greater than the inner diameter of the return water tank 11, and the minimum diameter of the sealing gasket 19 is less than the inner diameter of the return water tank 11. The elasticity of the sealing gasket 19 is utilized to squeeze the sealing gasket 19 and the inner wall of the return water tank 11 against each other, thereby achieving the goal of installing the baffle 18 on the top of the return water tank 11.

[0030] In this embodiment, the condenser cooler 5 includes an upper part 6 of the condenser cooler and a lower part 7 of the condenser cooler. The upper part 6 of the condenser cooler and the lower part 7 of the condenser cooler are connected by a flange. A sealing ring is arranged between the upper part 6 of the condenser cooler and the lower part 7 of the condenser cooler, which can improve the overall sealing of the condenser cooler 5. The distillation tube 9 is connected to the upper part 6 of the condenser cooler, and the return pipe 12 is connected to the lower part 7 of the condenser cooler. The detachable connection of the condenser cooler 5 facilitates the cleaning and maintenance of the interior of the condenser cooler 5.

[0031] In this embodiment, a liquid level column 13 is provided on the distillation barrel 1, and the liquid level column 13 is connected to the cavity of the heating cavity 15, so as to monitor the liquid level height of the heating cavity 15 in real time, and prevent the electric heater 16 from continuing to heat when the liquid in the heating cavity 15 has been distilled, thereby effectively preventing the occurrence of safety accidents.

[0032] In the present embodiment, a heat insulation layer is provided between the inner wall of the distillation barrel 1 and the heating cavity 15. The heat insulation layer is glass fiber wool felt. The glass fiber wool felt has good insulation and heat resistance, and the cost of the glass fiber wool felt is relatively low, which can effectively reduce the cost of manufacturing the distillation extraction device. The use of glass fiber wool felt for heat insulation can effectively prevent the temperature of the heating cavity 15 from escaping, and at the same time can reduce the temperature of the surface of the distillation barrel 1 to avoid burns to the operator.

[0033] In this embodiment, the distillation barrel 1 is provided with a drain pipe 8, which is connected to the heating chamber 15, and a stop valve is provided at the other end of the drain pipe 8; when the liquid level in the heating chamber 15 is too high or there are impurities left over from the distillation in the heating chamber 15, they can be discharged through the drain pipe 8.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
