[0062] The toggling component is arranged on the inner wall of the steam sterilization cylinder 1 and is used for toggling the Chinese medicine placed in the cylinder 31 .

[0063] The placement tube 31 is a cylindrical hollow mesh structure, and the cover plate above the placement tube 31 is separated from the body of the placement tube 31. The outer wall of the placement tube 31 is provided with an annular placement hole for placing Chinese medicine;

[0064] The bottom of the inner wall of the steam sterilization cylinder 1 is rotatably connected with a rotating shaft 7, and the rotating shaft 7 is hexagonal and plugged into the inner wall of the placement cylinder 31 to drive the placement cylinder 31 to rotate;

[0065] Two rotating shafts 7 are provided, the other rotating shaft 7 is rotatably connected to the cover 2, and a motor is installed on the top of the cover 2, the output end of the motor is connected to the upper rotating shaft 7, and the bottom of the upper rotating shaft 7 is inserted into the placement ring 33 to drive the placement ring 33 to rotate;

[0066] A plurality of spherical slide bars 32 are installed at the bottom of the placement tube 31 , and annular grooves are formed on the top of the placement ring 33 and the placement tube 31 , and the spherical slide bars 32 slide in the annular grooves.

[0067] The toggle assembly includes:

[0068] The multi-section plug rod 34 is plugged into the inner wall of the steam sterilization cylinder 1;

[0069] A connecting rod 35 is fixedly connected to the inserting rod 34, and one side of the connecting rod 35 extends to the inner wall of the placing tube 31, and is used to move the Chinese medicine in the placing tube 31;

[0070] A fixing sleeve 38, fixedly connected to the other end of the connecting rod 35;

[0071] The spherical rod 37 is movably connected to the inner wall of the fixed sleeve 38, and the outer wall of the spherical rod 37 is provided with a spring 39 for pushing the spherical rod 37 upward;

[0072] The wavy push block 36 is fixedly connected to the inner wall of the placement ring 33, and the wavy surface of the wavy push block 36 contacts the spherical rod 37 to resist the downward movement of the spherical rod 37.

[0073] The bottom of the spherical rod 37 is hinged with two levers 310 for moving the Chinese medicine;

[0074] The end of the first lever 310 away from the spherical rod 37 is hinged with a second lever 311, and the second lever 311 is attached to the bottom of the placement tube 31 for moving the Chinese medicine.

[0075] Working principle: When the Chinese medicine is sterilized by pressure steam, firstly, the cylinder 5 is started to operate, at which time the cylinder 5 pushes the cooling cylinder 41 to move upward, and releases the connection between the fixing rod 6 and the steam sterilization cylinder 1. At this time, the upper part of the cover 2 is directly removed from the steam sterilization pot 1;

[0076] Then, the placing cylinder 31 is sleeved on the inner wall of the lower rotating shaft 7, and rotated on the placing ring 33 through the spherical rod 37, and then the toggle assembly is installed in the steam sterilization cylinder 1 through the insertion rod 34, and then the upper cover plate of the steam sterilization cylinder 1 is sleeved on the lower rotating shaft 7, and the installation is carried out in sequence. After the installation is completed, the cover 2 and the pressure relief mechanism 4 thereon are inserted into the inner wall of the placing cylinder 31 through the upper rotating shaft 7, and connected to the steam sterilization cylinder 1 through the two fixed rods 6 to achieve fixation;

[0077] Then, the motor is started, and the upper shaft 7 is driven to rotate by the upper motor, and the uppermost placement tube 31 is driven to rotate, while the lower shaft 7 is driven to rotate, and the multiple placement tubes 31 are driven to rotate synchronously. At this time, the placement tube 31 rotates relative to the toggle assembly. At this time, when the wavy push block 36 rotates, the wave crest of its wavy groove surface will hit the spherical rod 37, and the spherical rod 37 will be squeezed to move downward. When the trough of the wavy groove surface hits the spherical rod 37, the spring 1 39 will push the spherical rod 37 to move upward, thereby synchronously driving the two toggle rods 1 310 to move up and down, so as to achieve the purpose of toggling the Chinese medicine. At the same time, in the process of moving up and down, the toggle rod 1 310 will push the toggle rod 2 311 to move, thereby changing the toggle state, achieving the purpose of toggling the Chinese medicine, and improving the toggle effect, so as to promote the contact between steam and Chinese medicine, improve the sterilization effect, and make the sterilization more thorough.

[0078] See also Figures 1 - 9 Based on the above embodiment, in another embodiment of the present invention, the pressure relief mechanism 4 includes:

[0079] The cooling cylinder 41 is disposed above the cover 2 and is annular in shape;

[0080] The distillation pool 42 is arranged on the inner wall of the cooling cylinder 41 and is used to store distilled water;

[0081] A plurality of connection blocks 43 are connected to the upper, lower and right side walls of the distillation pool 42 and to the inner wall of the cooling cylinder 41;

[0082] One end of a plurality of conduits 44 is connected to the top of the cover 2 , and the other end is fixedly passed through the cooling cylinder 41 and the distillation pool 42 .

[0083] One end of the conduit 44 is tapered and is disposed on the cover 2 , and is used to collect steam and pass it into the distillation pool 42 through the conduit 44 .

[0084] The pressure relief mechanism 4 also includes:

[0085] A pressure relief valve is installed on the outer wall of the cooling cylinder 41 and is connected to the main blocking conduit 44 in the distillation pool 42 to release the internal air pressure;

[0086] A push ring 46 is disposed in the distillation pool 42;

[0087] The high-pressure nozzle 45 is installed on the distillation pool 42 and penetrates the cooling cylinder 41 and the cover 2 to penetrate into the steam sterilization cylinder 1;

[0088] A push rod 47 is fixedly connected to the top of the push ring 46, and the push rod 47 movably passes through the distillation pool 42 and the cooling cylinder 41 and extends upward;

[0089] The reset spring 48 is sleeved on the outer wall of the push rod 47 and is used to reset the push rod 47 upward.

[0092] The bottom of the push plate 49 is in contact with the top of the push rod 47 and is used to push the push rod 47 downward.

[0093] Working principle: When sterilizing, the steam in the steam sterilization cylinder 1 will evaporate and enter above the lid 2, increasing the pressure inside the entire steam sterilization cylinder 1. After the steam sterilization is completed, by opening the pressure relief valve, the pressure inside the steam sterilization cylinder 1 is released. The air pressure and gas inside the steam sterilization cylinder 1 enter the distillation pool 42 through the conduit 44. After entering the cooling cylinder 41, it is cooled, condensing the steam and entering the distillation pool 42 for storage through the obliquely arranged conduit 44. By starting the cylinder 5 to move upward, the entire lid 2 and the cooling cylinder 41 will be pushed upward, and the push rod 47 will be pushed upward to contact the push plate 49, generating extrusion on the push rod 47. At this time, the push rod 47 will push the push ring 46 downward, squeezing the distilled water stored in the distillation pool 42 and squeezing it through the high-pressure nozzle 45, so as to spray the distilled water through the high-pressure nozzle 45 and enter the inner wall of the steam sterilization cylinder 1, spraying distilled water on the items on the inner wall of the steam sterilization cylinder 1 and cooling them, facilitating the removal of the items inside and improving work efficiency.
