[0033] Due to the hinge connection between the hinge block 5 and the hinge arm 6, the hinge arm 6 as a whole can rotate around the shaft, when the kettle door 7 is rotated to the inside of the door frame 4 under the driving of the hinge arm 6, at this time, the first pull rod 11 is pulled, at this time, the first pull rod 11 drives the gear 10 to rotate, since the gear 10 is in meshing connection with the rack 9, at this time, the gear 10 drives the door frame 4 as a whole to rotate through the rack 9, at this time, the four supporting blocks 15 are simultaneously rotated under the driving of the door frame 4, since the four supporting blocks 15 are designed, the door frame 4 is well supported, when the teeth inside the door frame 4 coincide with the teeth on the kettle door 7, at this time, the door frame 4 locks the kettle door 7, thereby the sealing between the inner container 2 and the kettle door 7 is enhanced.

[0034] As a preferred technical scheme of the utility model, the outer surface of the front face of the shell 1 movably sheaths a stop block 13, and the outer surface of the stop block 13 fixedly installs a second pull rod 14.

[0035] When the operator drives the stop block 13 to rotate by pulling the second pull rod 14, at this time, the stop block 13 will contact the arc-shaped block 12 in rotation, at this time, the stop block 13 locks the door frame 4 through the arc-shaped block 12.

[0036] Among them, the front end of the left side of the shell 1 is provided with an indicator lamp 19, and the middle section of the left side of the shell 1 is provided with an instrument 20

[0037] When the inner container 2 is attached to the kettle door 7, at this time, the indicator lamp 19 will light up, since the design of the instrument 20, the operator can conveniently monitor the pressure inside the inner container 2 and the outer container 3.

[0038] Among them, the rear end of the left side of the shell 1 fixedly installs an electric control box 21, and the left side of the electric control box 21 is provided with a touch screen 22.

[0039] Since the design of the electric control box 21 and the touch screen 22, the operator can conveniently control the pressure inside the inner container 2 and the outer container 3.

[0040] Among them, the inside of the top rear of the shell 1 fixedly sheaths a pressure relief valve 25, the outer surface of the bottom end of the pressure relief valve 25 movably sheaths the inside of the inner container 2 and the outer container 3 respectively,

[0041] When the pressure inside the inner container 2 or the outer container 3 is too high, the pressure relief valve 25 can be used to relieve the pressure outward.

[0042] Among them, the left side of the inside of the shell 1 fixedly installs a water tank 26, the left side of the water tank 26 fixedly installs a water level gauge 27, the outer surface of the water level gauge 27 fixedly sheaths the inside of the left side of the shell 1, and the inside of the back of the water tank 26 fixedly sheaths a water level monitor 30.

[0043] Due to the design of the water level gauge 27, the operator can conveniently monitor the water level in the water tank 26 in real time. Due to the design of the three water level monitors 30, when the water level in the water tank 26 is too high or too low, the alarm lamp 16 will issue an alarm.

[0044] The top end of the water tank 26 is internally fixedly sleeved with a water inlet 28, the outer surface of the top end of the water inlet 28 is fixedly sleeved with the inside of the top end of the shell 1, and the inside of the water tank 26 is fixedly installed with a heating wire 29.

[0045] Due to the design of the water inlet 28, the operator can conveniently add water to the inside of the water tank 26. Due to the design of the heating wire 29, the water in the water tank 26 can be heated.

[0046] The top end of the water tank 26 is internally fixedly sleeved with an air inlet pipe 31, and the other end of the air inlet pipe 31 is fixedly sleeved with a three-way pipe 23.

[0047] When the water in the water tank 26 boils, it will evaporate into water vapor, and at this time the water vapor will move to the inside of the three-way pipe 23 through the air inlet pipe 31.

[0048] The front end of the three-way pipe 23 is fixedly sleeved with an exhaust pipe 17, and the left side of the three-way pipe 23 is provided with a hand valve 24.

[0049] Due to the design of the hand valve 24, when the operator twists the hand valve 24, the water vapor in the air inlet pipe 31 cannot enter the inside of the three-way pipe 23.

[0050] The right end of the three-way pipe 23 is internally fixedly sleeved with a delivery pipe 18, and the outer surfaces of the bottom ends of the delivery pipe 18 are movably sleeved with the inside of the inner container 2 and the outside of the outer container 3.

[0051] When the water vapor in the air inlet pipe 31 enters the inside of the three-way pipe 23, at this time the water vapor will enter the inside of the inner container 2 through the delivery pipe 18, and then dewax the wax mold in the inside of the inner container 2. When the hand valve 24 is twisted, the high-pressure water vapor in the inside of the inner container 2 will flow back to the inside of the three-way pipe 23 through the delivery pipe 18, and then be discharged to the outside of the shell 1 through the exhaust pipe 17.

[0052] The working principle and use process of the utility model are as follows:

[0053] First, the operator pulls the handle 8, at this time the kettle door 7 will rotate with the hinge block 5 hinge as the axis, then the kettle door 7 will move to the inside of the door frame 4, at this time the operator pulls the first pull rod 11, at this time the first pull rod 11 will drive the gear 10 to rotate with the movable sleeve of the shell 1 as the axis, because the outer surface of the gear 10 is meshed with the outer surface of the rack 9, when the gear 10 rotates, it will drive the rack 9 to move, at this time the door frame 4 will rotate with the movable sleeve of the shell 1 as the axis under the drive of the rack 9, in this process, the four supporting blocks 15 will rotate at the same time, because of the design of the four supporting blocks 15, it will support the door frame 4 well, when the door frame 4 drives the arc block 12 to align with the stop block 13 in rotation, at this time the teeth in the door frame 4 will coincide with the teeth on the kettle door 7, at this time the door frame 4 will block the movement of the kettle door 7, thereby achieving the function of enhancing the sealing between the inner container 2 and the kettle door 7, then the operator pulls the second pull rod 14, at this time the second pull rod 14 will drive the stop block 13 to rotate with the movable sleeve of the shell 1 as the axis, when the outer surface of the stop block 13 contacts the outer surface of the arc block 12, at this time the stop block 13 will block the movement of the arc block 12, thereby locking the rotation of the door frame 4 as a whole.

[0054] Then the operator starts the heating wire 29, at this time the heating wire 29 will heat the water in the water tank 26, then the water in the water tank 26 will evaporate, at this time the water vapor in the water tank 26 will enter the inside of the inlet pipe 31, then the water vapor in the inlet pipe 31 will enter the inside of the inner container 2 through the three-way pipe 23 and the delivery pipe 18 in turn, thereby dewaxing the wax mold in the inner container 2, because of the design of the instrument 20, the operator can monitor the internal pressure of the inner container 2 and the outer container 3 in real time, thereby adjusting through the electric control box 21, because of the design of the pressure relief valve 25, when the pressure in the inner container 2 or the outer container 3 is too high, it can be released to the outside of the shell 1 through the pressure relief valve 25, because of the design of the three water level monitors 30, the water level in the water tank 26 can be monitored in real time, when the water level in the water tank 26 is lower than the lowermost water level monitor 30 or higher than the uppermost water level monitor 30, at this time the alarm lamp 16 will give an alarm, thereby reminding the operator to add water or stop adding water in the water tank 26, after the wax mold dewaxing is completed, at this time the operator turns the hand valve 24, at this time the water vapor in the inner container 2 will flow back through the delivery pipe 18, then the water vapor in the delivery pipe 18 will be discharged to the outside of the shell 1 through the three-way pipe 23 and the delivery pipe 18 in turn, thereby accelerating the cooling of the inner container 2.
