[0076] Embodiment 1

[0077] like Figures 1 to 3 As shown, the present invention discloses a frying pan.

[0078] The frying pot comprises an outer barrel 1 with an inner hollow interior and an opening at the top, an inner barrel 2 with an inner hollow interior and an opening at the top, and a barrel cover 3 capable of closing the top barrel opening of the inner barrel 2. The outer barrel 1 is cylindrical in shape. The inner barrel 2 is also cylindrical in shape. The outer barrel diameter of the inner barrel 2 is smaller than the barrel opening diameter of the outer barrel 1. Since the outer barrel diameter of the inner barrel 2 is smaller than the barrel opening diameter of the outer barrel 1, the inner barrel 2 can be loaded into the inner barrel 1 from the barrel opening of the outer barrel 1. The barrel cover 3 covers the barrel opening of the inner barrel 2 to close the barrel opening of the inner barrel 2.

[0079] In this embodiment, an outer barrel flange 11 of a circular ring structure extending horizontally outward is provided at the barrel opening of the outer barrel 1. An inner barrel flange 21 of a circular ring structure extending horizontally outward is provided at the barrel opening of the inner barrel 2. The outer diameter of the inner barrel flange 21 is larger than the barrel opening diameter of the outer barrel 1. The barrel height of the inner barrel 2 is smaller than the barrel height of the outer barrel 1. When the inner barrel 2 is placed into the outer barrel 1 from the top barrel opening of the outer barrel 1, the inner barrel flange 21 on the inner barrel 2 is pressed on the outer barrel flange 11 of the outer barrel 1.

[0080] When the inner barrel 2 is put into the outer barrel 1 , the inner barrel flange 21 of the inner barrel 2 is pressed against the outer barrel flange 11 of the outer barrel 1 , and a distance is left between the outer surface of the barrel bottom of the inner barrel 2 and the inner surface of the barrel bottom of the outer barrel 1 .

[0081] Preferably, two extensions 211 extending outward horizontally are provided on the outer edge of the inner barrel flange 21, and the extensions 211 are integrally formed with the inner barrel flange 21. The two extensions 211 are symmetrically arranged about the central axis of the inner barrel 2. The extensions 211 extend to the outside of the outer edge of the outer barrel flange 11. By providing the extensions 211 and extending the extensions 211 to the outside of the outer edge of the outer barrel flange 11, when the inner barrel 2 is taken out from the inner barrel 1, the inner barrel flange 21 can be lifted from the bottom of the extensions 211, thereby facilitating the inner barrel 2 to be lifted out of the inner barrel 1.

[0082] In this embodiment, when the inner barrel 2 is placed inside the outer barrel 1, since the bottom surface of the inner barrel flange 21 fits with the top surface of the outer barrel flange 11, and the outer diameter of the inner barrel 2 is smaller than the inner diameter of the outer barrel 1, a closed sealed cavity 4 is formed between the outer wall of the inner barrel 2 and the inner wall of the outer barrel 1. A pressure relief member 22 is installed on the inner barrel flange 21, and the pressure relief member 22 is connected to 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 connects the inside of the sealed cavity 4 with the external space of the outer barrel 1.

[0083] 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 barrel flange 21, and a vertically arranged gas channel 222 is arranged inside the valve body 221. One end of the gas channel 222 is connected to the sealing chamber 4, and the other end of the gas channel 222 is connected to the top end face of the valve body 221. A gravity valve cap 223 is arranged on the top of the valve body 221, and the gravity valve cap 223 covers the top of the valve body 221. The bottom of the gravity valve cap 223 is provided with a valve stem 2231 extending into the gas channel 222 to close the gas channel 222, and the valve stem 2231 and the gravity valve cap 223 are integrally formed. When the gravity valve cap 223 is covered on the valve body 221, the valve stem 2231 closes the gas passage 222. When the gravity valve cap 223 is removed from the valve body 221, the gas passage 222 connects the sealing chamber 4 with the outside air, so that the air inside the sealing chamber 4 can be discharged into the outside air.

[0084] A plurality of communication holes 23 are densely distributed at the bottom of the lateral barrel wall of the inner barrel 2, and the communication holes 23 penetrate the lateral barrel wall of the inner barrel 2. When the inner barrel 2 is located inside the outer barrel 1, the communication holes 23 connect the internal space of the inner barrel 2 with the internal space of the outer barrel 1.

[0085] When decocting the medicinal materials, first put the inner barrel 2 into the outer barrel 1, then put the medicine bag filled with the medicinal materials into the inner space of the inner barrel 2, and then add the water required for decocting the medicinal materials into the inner barrel 2. The water poured into the inner barrel 2 needs to ensure that the water level is above all the connecting holes 23. The barrel mouth of the inner barrel 2 is closed by the barrel cover 3, and finally the outer barrel 1 is heated by the induction cooker.

[0086] When the frying pot is heated, the frying pot is placed above the induction cooker. When the frying pot is simmered on a low heat using the induction cooker, the outer ring of the induction cooker heats the frying pot. As the water temperature in the frying pot continues to rise, the water vapor generated by the water heating enters the sealed cavity 4. As the water vapor continues to increase, the pressure inside the sealed cavity 4 will gradually increase. When the pressure inside the sealed cavity 4 is greater than the pressure inside the inner barrel 2, the pressure inside the sealed cavity 4 pushes the liquid medicine to be pressed into the inner barrel 2 through the connecting hole 23, and the liquid medicine pressed into the inner barrel 2 flushes the medicine bag placed in the inner barrel 2.

[0087] After the medicine liquid is pressed into the inner barrel 2, the pressure relief piece 22 is opened. When the pressure relief piece 22 is opened, the steam in the sealed chamber 4 is discharged through the pressure relief piece 22. When the steam is gradually discharged by the pressure relief piece 22, the air pressure inside the sealed chamber 4 gradually decreases. When the pressure inside the sealed chamber 4 is lower than the pressure inside the inner barrel 2, the medicine liquid in the inner barrel 2 is pressed into the sealed chamber 4 through the connecting hole 23.

[0088] By repeatedly controlling the pressure of the sealed cavity 4 and the internal space of the inner barrel 2, the liquid medicine is continuously flushed on the medicine bag, so that the liquid medicine and the medicine bag can be fully combined to ensure that the concentration of the decocted medicine soup is higher.

[0089] In this embodiment, a horizontally arranged rectangular bottom plate tray 5 is provided at the bottom of the outer barrel 1, and a receiving cavity 51 is provided on the bottom surface of the bottom plate tray 5. The bottom of the outer barrel 1 vertically penetrates the bottom plate tray 5 from the top of the bottom plate tray 5, and the bottom of the outer barrel 1 extends into the inside of the receiving cavity 51. The bottom plate tray 5 is fixedly connected to the outer barrel 1. There is a distance between the lateral cavity wall of the receiving cavity 51 and the bottom of the outer barrel 1. The height of the outer surface of the bottom of the outer barrel 1 is higher than the bottom surface of the bottom plate tray 5. When the frying pot is placed on a shelf or the ground, there is a space between the bottom of the outer barrel 1 and the shelf or the ground, so as to protect the outer surface of the bottom of the outer barrel 1, so that the outer surface of the bottom of the outer barrel 1 is not easily scratched when the outer barrel 1 is stored and taken out.

[0090] Embodiment 2

[0091] like Figures 4 to 10 The present invention discloses a micro-pressure circulation decoction unit.

[0092] The micro-pressure circulation boiling unit includes the boiling pot disclosed in the first embodiment and a frame 6, wherein the frame 6 includes an upper truss 61 and a lower truss 62 which are arranged opposite to each other at an upper and lower interval, 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 opposite to the four corners of the lower truss 62 one by one. Columns 63 are respectively arranged at the four corners of the upper truss 61. The column 63 is arranged vertically. The top of the column 63 is fixedly connected to the upper truss 61, and the bottom of the column 63 is fixedly connected to the lower truss 62. A support leg 64 is installed at the bottom end of the column 63.

[0093] Two heating modules 7 are installed at intervals 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 to heat the frying pot disclosed in the present invention. Two pressure-regulating devices 8 are arranged at intervals along the length direction of the upper truss 61 below the upper truss 61, and the pressure-regulating devices 8 correspond to the heating modules 7 one by one. The pressure-regulating devices 8 are located directly above the corresponding heating modules 7. The pressure-regulating devices 8 are connected to the upper truss 61 through a lifting control device 9, and the lifting control device 9 is vertically arranged. 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-regulating device 8. The lifting control device 9 drives the pressure-regulating device 8 to rise and fall in the vertical direction.

[0094] In this embodiment, the number of heating modules 7 and the gland pressure regulating device 8 is two. In practice, the number of heating modules 7 and the gland pressure regulating device 8 can be set according to the actual production output, and can be one, three, four or more. The number of heating modules 7 and the gland pressure regulating device 8 is the same, and one heating module 7 and one gland pressure regulating device 8 form a group.

[0095] When the medicinal materials are decocted, the decoction pot with the medicinal materials and water is placed above the heating module 7, and the lifting control device 9 drives the pressure regulating device 8 to move downward until the pressure regulating device 8 presses the inner barrel flange 21 of the decoction pot, and the pressure regulating device 8 applies pressure to the inner barrel flange 21, so that the inner barrel flange 21 can fit tightly with the outer barrel flange 11. At the same time, the pressure regulating device 8 can control the opening and closing of the pressure relief member 22 to adjust the air pressure inside the sealed cavity in the decoction pot.

[0096] In this embodiment, the heating module 7 includes a mounting bracket 71 in a rectangular structure, and the mounting bracket 71 is fixed on the lower truss 62. An installation cavity 711 is provided inside the mounting bracket 71. A mounting port 712 connected to the inside of the mounting cavity 711 is provided on the top end surface of the mounting bracket 71. An electromagnetic cooker 72 for heating the frying pot is movably connected inside the mounting cavity 711. The electromagnetic cooker 72 is placed horizontally, and the electromagnetic cooker 72 can move vertically inside the mounting cavity 711. When the frying pot needs to be heated, the frying pot is placed on the top end surface of the electromagnetic cooker 72, and the electromagnetic cooker 72 is turned on to heat the frying pot.

[0097] The four corners of the bottom of the induction cooker 72 are all provided with vertically arranged elastic floating brackets 73, and the top of the elastic floating bracket 73 is fixedly connected to the induction cooker 72. The bottom of the elastic floating bracket 73 is fixedly connected to the bottom surface of the cavity bottom of the mounting cavity 711. The elastic floating bracket 73 supports the induction cooker 72. When the frying pan is not placed on the induction cooker 72, the elastic floating bracket 73 supports the induction cooker 72 and makes the top end surface of the induction cooker 72 higher than the top end surface of the mounting bracket 71. When the frying pan is placed on the induction cooker 72, the induction cooker 72 gradually moves downward, and the elastic floating bracket 73 is compressed at this time.

[0098] Preferably, a vertically arranged guide sleeve 713 is fixed inside the installation cavity 711, and the induction cooker 72 passes through the inner hole of the guide sleeve 713, and the outer side wall surface of the induction cooker 72 abuts against the inner hole wall of the guide sleeve 713. The guide sleeve 713 provides guidance for the movement of the induction cooker 72, so that the induction cooker 72 moves in the vertical direction along the guide sleeve 713, thereby preventing the induction cooker 72 from being skewed when moving.

[0099] In this embodiment, a baffle 74 is fixed at the middle position of the top of the outer surface of each side wall of the mounting bracket 71, and the top of the baffle 74 is higher than the top end surface of the mounting bracket 71 and the top end surface of the induction cooker 72 when it is at the highest position. Among them, three baffles 74 are provided with chamfers 741 on the top of the side facing the induction cooker 72. When the frying pot is placed on the induction cooker 72, the bottom plate tray 5 of the frying pot is first inserted into the space surrounded by the four baffles 74. The four side wall outer surfaces of the bottom plate tray 5 are opposite to and abut against the side surfaces of the four baffles 74 facing the induction cooker 72. When the bottom plate tray 5 enters the space surrounded by the four baffles 74, the frying pot is in a vertical state as a whole.

[0100] When the frying pot is lowered and placed on the induction cooker 72, the bottom of the outer barrel 1 is located on the top end surface of the induction cooker 72. The weight of the frying pot and the weight of the medicinal materials and water inside the frying pot all act on the induction cooker 72, pressing the induction cooker 72 to move downward. At this time, the elastic floating bracket 73 is compressed to accumulate force until the bottom end surface of the bottom plate tray 5 abuts against the top end surface of the mounting bracket 71.

[0101] In this embodiment, the heating module 7 further includes a proximity photoelectric component 75 and a processor mounted on the mounting bracket 71. The proximity photoelectric component 75 includes a frame 751 fixed on the mounting bracket 71, and a proximity switch 752 is mounted on the frame 751, and the detection end of the proximity switch 752 faces the induction cooker 72. The proximity switch 752 and the induction cooker 72 are both connected to the processor signal, and the proximity switch 752 sends the detection signal to the processor, and the processor sends a control instruction to the induction cooker 72 according to the detection signal of the proximity switch 752, thereby controlling the opening and closing of the induction cooker 72.

[0102] When the elastic floating bracket 73 is not stressed and is compressed, the electromagnetic oven 72 is in the highest position, and the proximity switch 752 is located below the electromagnetic oven 72. When the frying pan is placed on the electromagnetic oven 72 so that the elastic floating bracket 73 is in a compressed and force-storing state, the electromagnetic oven 72 and the proximity switch 752 are horizontally opposite. When the electromagnetic oven 72 and the proximity switch 752 are horizontally opposite, the proximity switch 752 detects the electromagnetic oven 72, and the proximity switch 752 sends a detection signal to the processor, and the processor sends a start designation to the electromagnetic oven 72, and the electromagnetic oven 72 is turned on to heat the frying pan. When the electromagnetic oven 72 and the proximity switch 752 are in an up-and-down misalignment state, the electromagnetic oven 72 remains in a closed state.

[0103] Preferably, an adjustment slot 7511 is provided on the frame 751, and the length of the adjustment slot 7511 is set vertically. The proximity switch 752 is slidably connected in the adjustment slot 7511. A fixing plate 753 is fixed on the top of the frame 751, and a through hole is provided on the fixing plate 753 that vertically penetrates the fixing plate 753. An adjustment screw 754 that vertically passes through the through hole is slidably connected in the through hole, and a first nut 755 and a second nut 756 are threadedly connected to the adjustment screw 754.

[0104] The maximum width of the first nut 755 and the second nut 756 is greater than the diameter of the through hole. When the position of the proximity switch 752 needs to be adjusted, the first nut 755 and the second nut 756 are rotated to move the first nut 755 and the second nut 756 toward the top or bottom of the adjusting screw 754, so that the proximity switch 752 can be driven to move vertically in the adjusting slot 7511 to adjust the height position of the proximity switch 752.

[0105] In this embodiment, the gland pressure regulating device 8 includes a gland 81 arranged horizontally, and a concave cavity 811 is arranged on the bottom surface of the gland 81. When the gland 81 abuts against the upper surface of the inner barrel flange 21, the pressure relief member 22 is located inside the concave cavity 811. Inside the concave cavity 811, a manipulator mechanism 82 for controlling the opening or closing of the pressure relief member 22 is arranged.

[0106] Specifically, the manipulator mechanism 82 includes a valve body air release claw 821 movably arranged inside the concave cavity 811 and a control component 822 that drives the valve body air release claw 821 to move horizontally and vertically. The control component 822 is located between the pressure cover 81 and the valve body air release claw 821 and is fixedly connected to the pressure cover 81.

[0107] Specifically, the control component 822 includes a vertically arranged vertical moving cylinder 8221, and the vertical moving cylinder 8221 is fixed on the outer surface of the top end of the pressure cover 81. The piston rod of the vertical moving cylinder 8221 faces the bottom of the pressure cover 81. The piston rod of the vertical moving cylinder 8221 vertically penetrates the pressure cover 81 and extends into the concave cavity 811. An opening 812 is provided on the top surface of the pressure cover 81 for the piston rod of the vertical moving cylinder 8221 to pass through. A horizontally arranged lateral moving cylinder 8222 is fixed at the end of the piston rod of the vertical moving cylinder 8221, and the piston rod of the lateral moving cylinder 8222 faces the lateral cavity wall of the concave cavity 811. The valve body degassing claw 821 is fixed at the end of the piston rod of the lateral moving cylinder 8222.

[0108] When the piston rod of the vertical moving cylinder 8221 moves, the piston rod of the vertical moving cylinder 8221 drives the horizontal moving cylinder 8222 to be raised or lowered, and when the horizontal moving cylinder 8222 is raised or lowered, the valve body deflation claw 821 is raised or lowered synchronously with the horizontal moving cylinder 8222. When the piston rod of the horizontal moving cylinder 8222 moves, the piston rod of the horizontal moving cylinder 8222 drives the valve body deflation claw 821 to move in the horizontal direction.

[0109] In this embodiment, the valve body deflation claw 821 includes a horizontal portion 8211 in a horizontal shape and a vertical portion 8212 arranged vertically. The vertical portion of the valve body deflation claw 821 is fixed together with the piston rod of the horizontal moving cylinder 8222. A plurality of notches 8213 are arranged at intervals along the edge of the horizontal portion 8211 on a side of the horizontal portion 8211 away from the vertical portion 8212. The number of notches 8213 is the same as the number of the pressure relief member 22. The spacing between the notches 8213 is the same as the spacing between the pressure relief members 22.

[0110] When the pressure cover 81 is pressed on the frying pot, the valve body deflation claw 821 and the pressure relief member 22 are horizontally opposite to each other. At this time, the horizontal part 8211 is located below the gravity valve cap 223 of the pressure relief member 22, and the notch 8213 on the horizontal part 8211 is opposite to the pressure relief member 22. When the horizontal moving cylinder 8222 drives the valve body deflation claw 821 to approach the pressure relief member 22, the horizontal part 8211 extends to the bottom of the gravity valve cap 223. When the horizontal part 8211 extends to the bottom of the gravity valve cap 223, the vertical moving cylinder 8221 drives the horizontal moving cylinder 8222 and the valve body deflation claw 821 to be lifted at the same time, and the horizontal part 8211 lifts the gravity valve cap 223, thereby opening the pressure relief member 22. When the pressure relief part 22 needs to be closed, the vertical moving cylinder 8221 drives the horizontal moving cylinder 8222 and the valve body air release claw 821 to descend at the same time, and the horizontal part 8211 drops the gravity valve cap 223 to close the pressure relief part 22. The horizontal moving cylinder 8222 drives the valve body air release claw 821 to move laterally away from the gravity valve cap 223, so that the horizontal part 8211 is separated from the gravity valve cap 223.

[0111] Preferably, the horizontal portion 8211 and the vertical portion 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 by 90 degrees.

[0112] In this embodiment, the lifting control device 9 adopts a cylinder. Two lifting control devices 9 are arranged between each gland 81 and the upper truss 61. The two lifting control devices 9 are located on opposite sides of the gland 81. By locating the two lifting control devices 9 on opposite sides of the gland 81, when the lifting control device 9 drives the gland 81 to lift, the force borne by the gland 81 can be more uniform, making the gland 81 more stable during the lifting process.

[0113] In the present embodiment, a plurality of vertically arranged guide shaft assemblies 10 are further provided between the pressure cover 81 and the upper truss 61, and the length of the guide shaft assemblies 10 is retractable. There are a plurality of guide shaft assemblies 10 and they are arranged at intervals along the circumferential direction of the pressure 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 pressure cover 81. When the pressure cover 81 is lifted or lowered, the length of the guide shaft assembly 10 changes with the movement of the pressure cover 81. By providing a plurality of guide shaft assemblies 10 between the pressure cover 81 and the upper truss 61, the guide shaft assembly 10 can guide the movement of the pressure cover 81, ensure that the moving direction of the pressure cover 81 always remains in a vertical state, and avoid the pressure cover 81 from tilting during the movement.

[0114] Specifically, the guide shaft assembly 10 includes a coaxially arranged fixed sleeve 101 and a moving rod 102, one end of the moving rod 102 extends into the inner hole of the fixed sleeve 101, and the moving rod 102 can move in the inner hole of the fixed sleeve 101 along the axial direction of the fixed sleeve 101. The fixed sleeve 101 is fixedly connected to the upper truss 61. One end of the moving rod 102 located outside the fixed sleeve 101 is fixed to the gland 81.

[0115] When the gland 81 moves in the vertical direction, the moving rod 102 moves synchronously with the gland 81, and one end of the moving rod 102 that extends into the inner hole of the fixing sleeve 101 moves along the axial direction of the fixing sleeve 101. Through the cooperation between the moving rod 102 and the fixing sleeve 101, the movement of the gland 81 can be guided, so that when the gland 81 moves in the vertical direction, the gland 81 is not easy to shake, thereby improving the stability of the vertical movement of the gland 81.
