[0075] Embodiment one

[0076] As Figures 1 to 3 The utility model discloses a decocting pot.

[0077] The decocting pot includes the outer barrel 1 of the inside hollow top end opening, the inner barrel 2 of the inside hollow top end opening and the barrel cover 3 of the top barrel mouth of inner barrel 2 can be closed. The outer shape of outer barrel 1 is cylindrical. The outer shape of inner barrel 2 is also cylindrical. The outer barrel diameter of inner barrel 2 is less than the barrel mouth diameter of outer barrel 1. Because the outer barrel diameter of inner barrel 2 is less than the barrel mouth diameter of outer barrel 1, so that inner barrel 2 can be loaded into the inside of outer barrel 1 from the barrel mouth of outer barrel 1. The barrel cover 3 covers the barrel mouth of inner barrel 2 to close the barrel mouth of inner barrel 2.

[0078] In this embodiment, the outer barrel flange 11 of the circular ring structure extending outward horizontally is arranged at the barrel mouth of outer barrel 1. The inner barrel flange 21 of the circular ring structure extending outward horizontally is arranged at the barrel mouth of inner barrel 2. The outer diameter of inner barrel flange 21 is greater than the barrel mouth diameter of outer barrel 1. The barrel height of inner barrel 2 is less than the barrel height of outer barrel 1. When inner barrel 2 is put into the inside of outer barrel 1 from the top barrel mouth of outer barrel 1, the inner barrel flange 21 on inner barrel 2 is pressed on the outer barrel flange 11 of outer barrel 1.

[0079] When inner barrel 2 is put into the inside of outer barrel 1, the inner barrel flange 21 of inner barrel 2 is pressed on the outer barrel flange 11 of outer barrel 1, and the barrel bottom outer surface of inner barrel 2 and the barrel bottom inner surface of outer barrel 1 are kept a distance.

[0080] Preferably, the outer edge of inner barrel flange 21 is provided with two extending parts 211 extending outward horizontally, and the extending part 211 is integrally formed with the inner barrel flange 21. The two extending parts 211 are centrally symmetrically arranged with the central axis of inner barrel 2. The extending part 211 extends to the outside of the outer edge of outer barrel flange 11. By arranging the extending part 211 and extending the extending part 211 to the outside of the outer edge of outer barrel flange 11, when inner barrel 2 is taken out from the inside of outer barrel 1, the inner barrel flange 21 can be lifted from the lower part of extending part 211, so that inner barrel 2 is conveniently lifted out from the inside of outer barrel 1.

[0081] In the present embodiment, when the inner drum 2 is put into the outer drum 1, the bottom end surface of the inner drum flange 21 is fitted with the top end surface of the outer drum flange 11, and the outer diameter of the inner drum 2 is smaller than the inner diameter of the outer drum 1, so that a closed sealed cavity 4 is formed between the outer wall of the inner drum 2 and the inner wall of the outer drum 1. A pressure relief member 22 is installed on the inner drum flange 21, and the pressure relief member 22 is in communication with the inside of the sealed cavity 4. When the gravity valve cap of the pressure relief member 22 is opened, the pressure relief member 22 communicates the inside of the sealed cavity 4 with the outside space of the outer drum 1.

[0082] Specifically, the pressure relief member 22 adopts a gravity pressure limiting valve. The pressure relief member 22 includes a valve body 221 fixed on the inner drum flange 21, and a gas passage 222 vertically arranged in the inside of the valve body 221. One end of the gas passage 222 is in communication with the sealed cavity 4, and the other end of the gas passage 222 is in communication with the top end surface of the valve body 221. A gravity valve cap 223 is arranged on the top of the valve body 221, and covers the top of the valve body 221. The bottom of the gravity valve cap 223 is provided with a valve rod 2231 extending into the inside of the gas passage 222 to close the gas passage 222, and the valve rod 2231 is integrally formed with the gravity valve cap 223. When the gravity valve cap 223 covers the valve body 221, the valve rod 2231 closes the gas passage 222, and when the gravity valve cap 223 is removed from the valve body 221, the gas passage 222 communicates the sealed cavity 4 with the outside air, so that the air in the inside of the sealed cavity 4 can be discharged to the outside air.

[0083] A plurality of communication holes 23 are densely arranged on the bottom of the lateral drum wall of the inner drum 2, and the communication holes 23 penetrate the lateral drum wall of the inner drum 2. When the inner drum 2 is located in the inside of the outer drum 1, the communication holes 23 communicate the inside space of the inner drum 2 with the inside space of the outer drum 1.

[0084] When the medicinal materials are decocted, first, the inner drum 2 is put into the inside of the outer drum 1, then the medicine bag filled with medicinal materials is put into the inside space of the inner drum 2, and then the water required for decocting the medicinal materials is added into the inside of the inner drum 2. The water poured into the inner drum 2 needs to ensure that the water level is above all the communication holes 23. The drum opening of the inner drum 2 is closed by the drum cover 3, and finally the outer drum 1 is heated by the electromagnetic oven.

[0085] When the decocting pot is heated, the decocting pot is placed above the electromagnetic oven. When the decocting pot is simmered by using the electromagnetic oven, the outer ring of the electromagnetic oven is used to heat the decocting pot. The water in the decocting pot is heated to generate water vapor, which enters the sealed cavity 4. As the water vapor increases, the pressure in the sealed cavity 4 also gradually increases. When the pressure in the sealed cavity 4 is greater than the pressure in the inner space of the inner barrel 2, the pressure in the sealed cavity 4 pushes the medicinal liquid through the communication hole 23 and is pressed into the inner barrel 2. The medicinal liquid pressed into the inner barrel 2 flushes the medicinal bag placed in the inner barrel 2.

[0086] After the medicinal liquid is pressed into the inner barrel 2, the pressure relief part 22 is opened. When the pressure relief part 22 is opened, the steam in the sealed cavity 4 is discharged through the pressure relief part 22. When the steam is gradually discharged through the pressure relief part 22, the pressure in the sealed cavity 4 gradually decreases. When the pressure in the sealed cavity 4 is less than the pressure in the inner space of the inner barrel 2, the medicinal liquid in the inner barrel 2 is pressed into the sealed cavity 4 through the communication hole 23.

[0087] By repeatedly controlling the pressure of the sealed cavity 4 and the inner space of the inner barrel 2, the medicinal liquid can continuously flush the medicinal bag, so that the medicinal liquid and the medicinal bag can be fully combined, and the concentration of the decocted medicinal soup can be ensured to be larger.

[0088] In the embodiment, the bottom of the outer barrel 1 is provided with a horizontally arranged rectangular bottom plate tray 5, and the bottom end surface of the bottom plate tray 5 is provided with a containing cavity 51. The barrel bottom of the outer barrel 1 vertically penetrates the bottom plate tray 5 from the top end of the bottom plate tray 5, and the barrel bottom of the outer barrel 1 extends into the inside of the containing cavity 51. The bottom plate tray 5 is fixedly connected with the outer barrel 1. The lateral cavity wall of the containing cavity 51 is spaced apart from the barrel bottom of the outer barrel 1. The height of the outer surface of the barrel bottom of the outer barrel 1 is higher than the bottom end surface of the bottom plate tray 5. When the decocting pot is placed on the shelf or the ground, the barrel bottom of the outer barrel 1 is spaced apart from the shelf or the ground, so that the outer surface of the barrel bottom of the outer barrel 1 is protected, and the outer surface of the barrel bottom of the outer barrel 1 is not easily scratched when the outer barrel 1 is stored and taken.

[0090] As Figures 4 to 10 The utility model discloses a kind of micro-pressure circulation decocting units.

[0091] The micro-pressure circulation decocting unit comprises the decocting pot disclosed in Embodiment One and a rack 6, which comprises an upper truss 61 and a lower truss 62 arranged oppositely in a vertical direction, and the upper truss 61 and the lower truss 62 are parallel to each other. In this embodiment, the upper truss 61 and the lower truss 62 are both rectangular frame structures. The four corners of the upper truss 61 are arranged oppositely in a vertical direction to the four corners of the lower truss 62. A vertical column 63 is arranged at each of the four corners of the upper truss 61. The vertical column 63 is arranged vertically. The top of the vertical column 63 is fixedly connected to the upper truss 61, and the bottom of the vertical column 63 is fixedly connected to the lower truss 62. A supporting leg 64 is arranged at the bottom end of the vertical column 63.

[0092] Two heating modules 7 are arranged on the upper surface of the lower truss 62 along the length direction of the lower truss 62, and the heating modules 7 are used for heating the decocting pot disclosed in the utility model. Two pressure cap pressure regulating devices 8 are arranged on the lower surface of the upper truss 61 along the length direction of the upper truss 61, and the pressure cap pressure regulating devices 8 correspond to the heating modules 7 one by one. The pressure cap pressure regulating device 8 is located directly above the corresponding heating module 7. The pressure cap pressure regulating device 8 is connected to the upper truss 61 through a lifting control device 9, and the lifting control device 9 is arranged vertically. One end of the lifting control device 9 is fixed to the upper truss 61, and the other end of the lifting control device 9 is connected to the pressure cap pressure regulating device 8. The lifting control device 9 drives the pressure cap pressure regulating device 8 to rise and fall in the vertical direction.

[0093] In this embodiment, the number of the heating modules 7 and the pressure cap pressure regulating devices 8 is two, and in practice, the number of the heating modules 7 and the pressure cap pressure regulating devices 8 can be set according to the actual production output, which can be one, three, four or more. The number of the heating modules 7 and the pressure cap pressure regulating devices 8 is the same, and one heating module 7 and one pressure cap pressure regulating device 8 form a group.

[0094] When the medicinal materials are decocted, the decocting pot containing the medicinal materials and water is placed above the heating module 7. The lifting control device 9 drives the pressure cap pressure regulating device 8 to move downward until the pressure cap pressure regulating device 8 presses the inner barrel flange 21 of the decocting pot. The pressure cap pressure regulating device 8 applies pressure to the inner barrel flange 21, so that the inner barrel flange 21 and the outer barrel flange 11 can be tightly attached to each other. At the same time, the pressure cap pressure regulating device 8 can control the opening and closing of the pressure relief part 22, so as to adjust the size of the air pressure in the sealed cavity of the decocting pot.

[0095] In the embodiment, the heating module 7 comprises a mounting bracket 71 in the shape of a rectangular body, which is fixed on the lower truss 62. The mounting bracket 71 is internally provided with a mounting cavity 711.

When the cooking pot needs to be heated, the cooking pot is placed on the top end face of the electromagnetic oven 72, and the electromagnetic oven 72 is turned on to heat the cooking pot.

[0096] The electromagnetic oven 72 is provided with a vertically arranged elastic floating bracket 73 at each of the four corners of the bottom end. The top end of the elastic floating bracket 73 is fixedly connected with the electromagnetic oven 72. The bottom end of the elastic floating bracket 73 is fixedly connected with the bottom surface of the mounting cavity 711. The elastic floating bracket 73 supports the electromagnetic oven 72. When the cooking pot is not placed on the electromagnetic oven 72, the elastic floating bracket 73 supports the electromagnetic oven 72 and makes the top end face of the electromagnetic oven 72 higher than the top end face of the mounting bracket 71. When the cooking pot is placed on the electromagnetic oven 72, the electromagnetic oven 72 gradually moves downward, and the elastic floating bracket 73 is compressed at this time.

[0097] Preferably, a vertically arranged guide sleeve 713 is fixedly connected in the mounting cavity 711. The electromagnetic oven 72 passes through the inner hole of the guide sleeve 713, and the outer side wall surface of the electromagnetic oven 72 abuts against the hole wall of the inner hole of the guide sleeve 713. The guide sleeve 713 provides guidance for the movement of the electromagnetic oven 72, so that the electromagnetic oven 72 moves vertically along the guide sleeve 713, preventing the electromagnetic oven 72 from tilting when moving.

[0098] In the embodiment, the mounting bracket 71 is fixedly connected with a baffle 74 at the top middle position of each of the outer side surfaces of the side walls. The top end of the baffle 74 is higher than the top end face of the mounting bracket 71 and the top end face of the electromagnetic oven 72 when the electromagnetic oven 72 is in the highest position. Three baffles 74 are provided with chamfers 741 towards the top side of the electromagnetic oven 72. When the cooking pot is placed on the electromagnetic oven 72, the bottom plate tray 5 of the cooking pot is first clamped into the space surrounded by the four baffles 74. The four side wall outer side surfaces of the bottom plate tray 5 abut against the four side surfaces of the baffles 74 towards the electromagnetic oven 72 one by one. When the bottom plate tray 5 enters the space surrounded by the four baffles 74, the cooking pot is in a vertical state as a whole.

[0099] When the decocting pot is placed on the electromagnetic stove 72, the bottom of the outer barrel 1 is located on the top end surface of the electromagnetic stove 72. The weight of the decocting pot and the weight of the medicinal materials and water inside the decocting pot are all applied to the electromagnetic stove 72, which is pressed to move downward, and at this time, the elastic floating support 73 is compressed to store energy until the bottom end surface of the bottom tray 5 abuts against the top end surface of the mounting support 71.

[0101] When the elastic floating support 73 is not stressed and is compressed, the electromagnetic stove 72 is in the highest position, and the proximity switch 752 is located below the electromagnetic stove 72. When the decocting pot is placed on the electromagnetic stove 72 to make the elastic floating support 73 in the compressed energy storage state, the electromagnetic stove 72 is horizontally opposite to the proximity switch 752. When the electromagnetic stove 72 is horizontally opposite to the proximity switch 752, the proximity switch 752 detects the electromagnetic stove 72, and the proximity switch 752 sends detection signals to the processor, and the processor sends an opening instruction to the electromagnetic stove 72, and the electromagnetic stove 72 is opened to heat the decocting pot. When the electromagnetic stove 72 and the proximity switch 752 are in an up-down misalignment state, the electromagnetic stove 72 remains in a closed state.

[0102] Preferably, an adjusting groove 7511 is formed on the frame body 751, and the length of the adjusting groove 7511 is vertically arranged. The proximity switch 752 is slidingly connected in the adjusting groove 7511. A fixed plate 753 is fixed on the top of the frame body 751, and a through hole penetrating through the fixed plate 753 is formed on the fixed plate 753.

[0103] The maximum width of the first nut 755 and the second nut 756 is greater than the hole diameter of the through hole. When it is necessary to adjust the position of the proximity switch 752, the first nut 755 and the second nut 756 are rotated to move the first nut 755 and the second nut 756 towards the top end or the bottom end of the adjusting screw 754, so as to drive the proximity switch 752 to move in the vertical direction in the adjusting groove 7511, and the height position of the proximity switch 752 is adjusted.

[0104] In the embodiment, the gland pressure regulating device 8 comprises a horizontally arranged gland 81, and the bottom end surface of the gland 81 is provided with a recessed cavity 811. When the gland 81 abuts against the upper surface of the inner drum flange 21, the pressure relief member 22 is located inside the recessed cavity 811. Inside the recessed cavity 811 is arranged a mechanical mechanism 82 for controlling the opening and closing of the pressure relief member 22.

[0105] Specifically, the mechanical mechanism 82 comprises a valve body air release claw 821 movably arranged inside the recessed cavity 811, and a control assembly 822 for driving the valve body air release claw 821 to move in the horizontal direction and the vertical direction, and the control assembly 822 is located between the gland 81 and the valve body air release claw 821 and is fixedly connected with the gland 81.

[0106] Specifically, the control assembly 822 comprises a vertically arranged vertical movement air cylinder 8221 fixedly arranged on the top end outer surface of the gland 81. The piston rod of the vertical movement air cylinder 8221 is directed downward of the gland 81. The piston rod of the vertical movement air cylinder 8221 vertically penetrates the gland 81 and extends into the recessed cavity 811. An opening 812 is arranged on the top end surface of the gland 81 for the piston rod of the vertical movement air cylinder 8221 to pass through. A horizontally arranged horizontal movement air cylinder 8222 is fixedly arranged on the end head of the piston rod of the vertical movement air cylinder 8221, and the piston rod of the horizontal movement air cylinder 8222 is directed towards the lateral cavity wall of the recessed cavity 811. The valve body air release claw 821 is fixedly arranged on the end head of the piston rod of the horizontal movement air cylinder 8222.

[0107] When the piston rod of the vertical movement air cylinder 8221 moves, the piston rod of the vertical movement air cylinder 8221 drives the horizontal movement air cylinder 8222 to be lifted or lowered, and when the horizontal movement air cylinder 8222 moves up or down, the valve body air release claw 821 is lifted or lowered synchronously with the horizontal movement air cylinder 8222. When the piston rod of the horizontal movement air cylinder 8222 moves, the piston rod of the horizontal movement air cylinder 8222 drives the valve body air release claw 821 to move in the horizontal direction.

[0108] In the embodiment, the valve body air release claw 821 comprises a horizontal part 8211 in horizontal shape and a vertical part 8212 in vertical arrangement. The vertical part of the valve body air release claw 821 is fixed with the piston rod of the transverse moving cylinder 8222. A plurality of apertures 8213 are arranged along the edge of the horizontal part 8211 at the side away from the vertical part 8212. The number of the apertures 8213 is the same as the number of the pressure relief pieces 22. The interval between the apertures 8213 is the same as the interval between the pressure relief pieces 22.

[0109] When the pressure cover 81 is pressed on the boiling pot, the valve body air release claw 821 is transversely opposite to the pressure relief piece 22, at this time, the horizontal part 8211 is below the gravity valve cap 223 of the pressure relief piece 22, and the apertures 8213 on the horizontal part 8211 are opposite to the pressure relief pieces 22 one by one. When the transverse moving cylinder 8222 drives the valve body air release claw 821 to approach the pressure relief piece 22, the horizontal part 8211 extends below the gravity valve cap 223. When the horizontal part 8211 extends below the gravity valve cap 223, the vertical moving cylinder 8221 drives the transverse moving cylinder 8222 and the valve body air release claw 821 to be lifted at the same time, the horizontal part 8211 lifts the gravity valve cap 223, thereby opening the pressure relief piece 22. When it is needed to close the pressure relief piece 22, the vertical moving cylinder 8221 drives the transverse moving cylinder 8222 and the valve body air release claw 821 to be lowered at the same time, the horizontal part 8211 drops the gravity valve cap 223, thereby closing the pressure relief piece 22, the transverse moving cylinder 8222 drives the valve body air release claw 821 to be transversely away from the gravity valve cap 223, so that the horizontal part 8211 is separated from the gravity valve cap 223.

[0110] Preferably, the horizontal part 8211 and the vertical part 8212 of the valve body air release claw 821 are integrally formed, and the valve body air release claw 821 is formed by bending a plate material by 90°.

[0111] In the embodiment, the lifting control device 9 adopts a cylinder. Two lifting control devices 9 are arranged between each pressure cover 81 and the upper truss 61. The two lifting control devices 9 are located at the opposite sides of the pressure cover 81. By locating the two lifting control devices 9 at the opposite sides of the pressure cover 81, the lifting control device 9 can make the force borne by the pressure cover 81 more uniform when driving the pressure cover 81 to be lifted, and make the pressure cover 81 more stable during the lifting process.

[0112] In the embodiment, a plurality of vertical guide shaft assemblies 10 are arranged between the cover 81 and the upper truss 61, and the length of the guide shaft assembly 10 is telescopic. The guide shaft assemblies 10 are arranged in a plurality of numbers and are arranged in a circumferential direction of the cover 81. The top end of the guide shaft assembly 10 is fixed to the upper truss 61, and the bottom end of the guide shaft assembly 10 is fixed to the cover 81. When the cover 81 is lifted or lowered, the length of the guide shaft assembly 10 changes with the movement of the cover 81. By arranging a plurality of guide shaft assemblies 10 between the cover 81 and the upper truss 61, the guide shaft assembly 10 can guide the movement of the cover 81, so that the movement direction of the cover 81 always remains vertical, avoiding the inclination of the cover 81 during movement.

[0113] Specifically, the guide shaft assembly 10 comprises a fixed sleeve 101 and a movable rod 102 coaxially arranged. One end of the movable rod 102 extends into the inner hole of the fixed sleeve 101, and the movable rod 102 can move in the axial direction of the fixed sleeve 101. The fixed sleeve 101 is fixedly connected to the upper truss 61. The end of the movable rod 102 outside the fixed sleeve 101 is fixed to the cover 81.

[0114] When the cover 81 moves in the vertical direction, the movable rod 102 moves synchronously with the cover 81, and the end of the movable rod 102 extending into the inner hole of the fixed sleeve 101 moves in the axial direction of the fixed sleeve 101. Through the cooperation between the movable rod 102 and the fixed sleeve 101, the movement of the cover 81 is guided, so that the cover 81 is not easy to shake when moving in the vertical direction, thereby improving the stability of the vertical movement of the cover 81.
