s1, placing herbaceous plants on the inner side of a bottom frame (2), wherein the bottom end of a threaded rod (23) at the bottom of a top frame (1) corresponds to an opening at the top of an inner frame (24), then rotating a rotating frame (21), enabling the top frame (1) to be correspondingly placed on the top of the bottom frame (2) by utilizing the spiral effect of the rotating frame (21) and an inserting rod (22), connecting the output end of a cylinder (19) with the top end of a pull rod (17), and utilizing the cylinder (19) to work and cooperate, so that a cover plate (18) is conveniently covered on the opening at the top of the top frame (1);

s2, hot water is introduced into the bottom frame (2) through the water inlet (27), the rotating frame (21) is rotated, when the top frame (1) moves up and down at the top of the bottom frame (2) due to the spiral effect of the rotating frame (21) and the inserting rod (22), the rotating sleeve (25) is in spiral fit with the threaded rod (23) through the internal thread strip, and when the top frame (1) moves up and down at the top of the inner frame (24) through the threaded rod (23), the rotating sleeve (25) drives the vertical plate (26) to bidirectionally rotate at the inner side of the bottom frame (2), and essence in herbaceous plants is extracted through stirring and soaking modes in the hot water;

s3, when the top frame (1) moves downwards, after the bottom of the extraction frame (3) contacts essence, the leakage holes (6) at the bottom of the extraction frame (3) prevent herbaceous plants from entering the extraction frame (3), when the bottom of the extraction frame (3) contacts herbaceous plants or the essence in the bottom frame (2) is extruded due to the downward movement of the top frame (1), the pressure enables the extraction frame (3) to gradually enter the top frame (1), the extraction frame (3) utilizes the top frame (1) to be matched with the extrusion springs (5), and the essence enters the extraction frame (3) through the leakage holes (6) until the bottom of the liquid inlet pipe (8) at the bottom of the extraction pipe (7) contacts the essence;

s4, due to the limitation of the ring frame (13) on the extraction tube (7), when the extraction frame (3) moves upwards, the extraction frame (3) utilizes the screw rod (11) and the screw cap (12) to enable the piston (10) to move upwards on the inner side of the extraction tube (7), the air pressure on the inner side of the extraction tube (7) is reduced by the aid of the upward-moving piston (10), the essence on the inner side of the extraction frame (3) is extracted by the aid of the air pressure, herbaceous plants and particles in the essence are filtered by the aid of the filter cotton (9), extraction of the essence is completed through the extraction tube (7), and the downward-moving top frame (1) is stopped at the moment;

s5, moving the top frame (1) upwards until the elastic force of the spring (5) enables the extraction frame (3) to gradually enter the inner side of the bottom frame (2), starting the air cylinder (19), enabling the air cylinder (19) to pull the ring frame (13) upwards by means of the pull rod (17), when the ring frame (13) moves upwards on the surface of the ring column (14) by means of the lantern ring (15), driving the extraction pipe (7) to move upwards by the ring frame (13), when the top surface of the ring frame (13) contacts with the screw cap (12) at the bottom, enabling the piston (10) to synchronously move upwards by the ring frame (13) by means of the screw cap (12) and the screw rod (11), stopping the air cylinder (19), pulling the cover plate (18), enabling the cover plate (18) to continuously move upwards by means of the air cylinder (19) until the connecting plate at the bottom end of the pull rod (17) contacts with the top end of the vertical groove, screwing the top screw cap (12), and driving the piston (10) to synchronously move upwards when the extraction pipe (7) moves upwards on the inner side of the ring frame (13), until the extraction pipe (7) and the piston (10) together with the piston (10) are used for extracting herbal essence from the inner side of the plant preparation.
