[0034] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not used to limit the present utility model.

[0035] As Figures 1 to 6 shown, the present utility model discloses an electric cooking pressure cooker, which includes a pot body shell 1. The pot body shell 1 is provided with an inner container 2. The inner container 2 is fixedly connected to the pot body shell 1 by screwing in screws at the bottom, so as to be integrally connected with the pot body shell 1. A heating device 3 is connected to the inner container 2 for heating the inner container 2; in this embodiment, the heating device 3 is a heating tube, and the heating tube is connected to the bottom surface of the inner container 2. After the heating tube is powered on, it generates heat to heat the inner container 2.

[0036] As Figure 3 、 Figure 5 and Figure 7As shown, after the inner pot 2 is fixed to the pot body shell 1, a distance is maintained between the outer wall of the inner pot 2 and the inner wall of the pot body shell 1 to form an isolation chamber 7. A heat dissipation hole 101 is provided at the bottom of the pot body shell 1, and the isolation chamber 7 communicates with the heat dissipation hole 101. The function of the isolation chamber 7 is to keep a distance between the inner wall of the pot body shell 1, the heating device 3, and the inner pot 2, without contact, to prevent the high temperature of the heating device 3 and the inner pot 2 from being conducted to the pot body shell 1, resulting in overheating. The high-temperature hot air generated by the heating device 3 and the inner pot 2 will be discharged through the isolation chamber 7 and the heat dissipation hole 101. Support feet 8 are provided at the bottom of the pot body shell 1. In addition to having a supporting function, the support feet 8 also form a gas flow space below the heat dissipation hole 101, that is, the effect of raising the lower bottom surface of the pot body shell 1 is achieved, facilitating the flow of gas into the heat dissipation hole 101. Since the heating device 3 is powered on, another function of the isolation chamber 7 is to keep a certain height distance between the heating device 3 and the heat dissipation hole 101. Since during cleaning, moisture may flow into the interior of the pot body shell 1 from the heat dissipation hole 101, quickly tilting the pot body shell 1 at this time can cause the moisture to quickly flow out from the heat dissipation hole 101, preventing the moisture from coming into contact with the heating device 3 and avoiding affecting the heating device 3.

[0037] A handle 4 is connected to the pot body shell 1. As Figure 6 shown, the handle 4 can be designed to open and close up and down. A circuit chamber 401 is enclosed on the handle 4. The circuit chamber 401 can be used to place circuit boards and other electronic components. There is a height difference between the handle 4 and the bottom of the pot body shell 1. As Figure 1 shown, the handle 4 is located at a position near the upper end of the pot body shell 1, which is not only beneficial for holding. Since the circuit chamber 401 contains circuit boards and other electronic components, and there is a heat dissipation hole 101 at the bottom of the pot body shell 1, there is a risk of water ingress. Therefore, keeping the circuit boards and other electronic components away from the bottom of the pot body shell 1 can effectively reduce the risk of water ingress into the circuit boards and other electronic components.

[0038] A circuit board 5 is provided in the circuit chamber 401. A holding position 402 is formed at one end of the handle 4 away from the inner pot 2. When cooking food or cleaning, a person's hand holds the holding position 402. An operation panel 6 is provided on the side of the holding position 402 close to the inner pot 2. The operation panel 6 is electrically connected to the circuit board 5, and the heating device 3 is electrically connected to the circuit board 5. The circuit board 5 can preset relevant execution instructions. When operating on the operation panel 6, relevant signals are transmitted to the circuit board 5, and the circuit board 5 will give corresponding feedback. For example, when operating the heating function on the operation panel 6, the circuit board 5 receives relevant signals and will transmit them to the heating device 3 for heating.

[0039] Since the circuit board and other electronic components are located in the handle 4, and when a person cleans, they hold the grip position 402 for cleaning. According to the operating habits of people, the handle 4 is in a high position, which can prevent water from flowing down to the handle 4. Therefore, the risk of water seepage into the circuit board and other electronic components is also reduced. And the handle 4 can be designed to be in a state of upper and lower covers closing, such as Figure 6 shown. The closing part is tightly combined and not easy to seep water. The operation panel 6 is arranged beside the grip position 402, which is helpful for one-handed operation when holding, and is very convenient. Although the heating device 3 is located below the inner pot 2, due to the isolation chamber 7 for a certain distance isolation, and the circuit board 5 is connected to the heating device 3 through wires, and the interface between the wires and the heating device 3 can also be treated with good glue sealing, so the risk of circuit water seepage is also reduced.

[0040] A power socket 403 is arranged at the end of the grip position 402. The power socket 403 is electrically connected to the circuit board 5. By inserting a power cord into the power socket 403, the circuit board 5 and its connected components can be heated. As mentioned above, when cleaning, the handle 4 is in a high position. Therefore, designing the power socket 403 at the end of the grip position 402 can also effectively prevent water from entering during cleaning.

[0041] The inner pot 2 is provided with a perforation, and a pressure sensor or a temperature sensor 9 is installed in the perforation for detecting the internal pressure or heating temperature of the inner pot 2. The pressure sensor and the temperature sensor 9 are electrically connected to the circuit board 5. In this embodiment, the temperature sensor 9 is a thermistor temperature sensor. One application method of the temperature sensor 9 is to control the heating temperature of the heating device 3 for the inner pot 2. For example, when the temperature sensor 9 detects that the internal heating temperature of the inner pot 2 reaches the preset value of the circuit board 5, the temperature sensor 9 will send relevant instructions to the circuit board 5 to make the circuit board 5 control the heating device 3 to stop heating.

[0042] The handle 4 extends straight outwards, such as Figure 4 shown. The inner pot 2 and the pot body shell 1 are symmetrically arranged with respect to the central axis in the length direction of the handle 4, which makes it have good balance when held by a person.

[0043] Such as Figures 7 to 12As shown in the figure, it further includes a pot lid 10. The pot lid 10 is detachably connected to the outer shell 1 of the pot body. A plurality of first buckles 201 extending horizontally outward are annularly arranged at the upper end edge of the inner pot 2. A plurality of second buckles 1001 extending horizontally toward the center are annularly arranged inside the pot lid 10. An embedding position 1002 is arranged beside the second buckle 1001. The numbers of the second buckle 1001 and the embedding position 1002 correspond to those of the first buckle 201. The pot lid 10 is fixed to the inner pot 2. The fixing method of the pot lid 10 and the inner pot 2 is that when the embedding position 1002 of the pot lid 10 is aligned with the first buckle 201 and put down (at this time, the second buckle 1001 is lower than the first buckle 201), and the pot lid 10 is rotated relative to the inner pot 2, from the top view, the first buckle 201 and the second buckle 1001 overlap, that is, the second buckle 1001 is located below the first buckle 201, so as to limit the pot lid 10 and prevent the pot lid 10 from being pulled up. When the pot lid 10 needs to be opened, operate in the reverse direction, rotate the pot lid 10 in the reverse direction to misalign the first buckle 201 and the second buckle 1001, that is, align the embedding position 1002 of the pot lid 10 with the first buckle 201 again, and then the pot lid 10 can be pulled up. Since this electric cooking pressure cooker is a pressure cooker, this design can tightly fix the pot lid 10 and the inner pot 2, and prevent them from separating due to the large air pressure in the inner pot 2 during operation.

[0044] The pot lid 10 is provided with a pin 1003 for limiting the further rotation of the pot lid 10 relative to the inner pot 2. The pin 1003 and the first buckle 201 are on the same horizontal plane. Combining Figure 9 and Figure 10 it can be seen that the rotation space of the pin 1003 is located between two adjacent first buckles 201. The pin 1003 is used in cooperation with the first buckles 201 on both sides of it. Assuming that when the pin 1003 stops at one side of a first buckle 201, the first buckle 201 and the second buckle 1001 are completely misaligned, and at this time the pot lid 10 can be pulled up. When the pot lid 10 is rotated to make the pin 1003 stop at the other side of a first buckle 201, the first buckle 201 and the second buckle 1001 are completely overlapped, and at this time the pot lid 10 cannot be pulled up. Therefore, when the pot lid 10 is rotated, when it is felt that the pin 1003 touches the first buckle 201, the rotation can be stopped. The cooperation between the pin 1003 and the first buckle 201 is to achieve the purpose of limiting the further rotation of the pot lid 10 relative to the inner pot 2.

[0045] If the pin 1003 is stationary, it will rotate for a long time and collide with the first buckle 201, which is easy to cause wear. Therefore, this solution adopts the following method: the pot cover 10 is rotatably provided with a movable plate 1004, the pin 1003 is connected to the movable plate 1004, the pot cover 10 has a accommodating chamber 1005, and a spring 1006 is sleeved on the pin 1003. One end of the spring 1006 abuts against the accommodating chamber 1005, and the other end of the spring 1006 abuts against the movable plate 1004; that is, the pin 1003 can be retracted to a certain extent in the direction of the accommodating chamber 1005, so as to prevent the pot cover 1003 from being damaged. Figure 10 It can be seen that both sides of the first buckle 201 are formed into an inclined and smooth shape. Therefore, when the pot cover 10 rotates and causes the pin 1003 to collide with the side of the first buckle 201, the pin 1003 can retract to a certain extent along the slope of the side of the first buckle 201, thereby converting the original lateral impact force of the pin 1003 on the first buckle 201 into pressure on the spring 1006, and the pin 1003 retracts slightly. When the human hand stops the rotation force, the spring 1006 resets and causes the pin 1003 to extend slightly and stop at the side of the first buckle 201, which can effectively avoid damage caused by a direct collision between the pin 1003 and the first buckle 201.

[0046] A high-pressure automatic exhaust device 11 and a manual exhaust device 12 are provided on the top of the pot cover 10; the high-pressure automatic exhaust device 11 includes an exhaust chamber 1102, and a float 1101 is movably arranged in the exhaust chamber 1102. When the pot cover 10 is fixed to the inner pot 2, the internal space of the inner pot 2 is connected to the exhaust chamber 1102. When the internal pressure of the inner pot 2 increases, the float 1101 will rise due to the push of the high-pressure gas, thereby blocking the exhaust chamber 1102 and preventing exhaust (from Figure 8 as well as Figure 12 It can be seen that the circumferential edge of the axial body of the float 1101 is provided with an annular plate, the diameter of which is larger than the aperture of the upper opening of the exhaust chamber 1102. Therefore, when the float 1101 rises and the annular plate abuts against the upper opening of the exhaust chamber 1102, the exhaust chamber 1102 will be blocked), thereby helping to maintain high pressure in the inner liner 2.

[0047] like Figure 12As shown, the manual exhaust device includes an exhaust channel 1201, a rotating plate 1202 and a pressing block 1203. A valve head 1204 is movably provided on the exhaust channel 1201. The lower end of the valve head 1204 is plugged into the upper part of the exhaust channel 1201. The exhaust channel 1201 is connected to the inner pot 2. The pressing block 1203 is movably arranged on the pot cover 10. One end of the rotating plate 1202 extends to the lower part of the valve head 1204, and the other end of the rotating plate 1202 extends to the pressing block 1203. The rotating plate 1202 is rotatably arranged, so when the food is cooked and the pot cover 10 is opened, the high pressure in the inner pot 2 must be discharged first, and the pressing block 1203 is pressed down at this time, so that the end of the rotating plate 1202 sinks, and the end of the rotating plate 1202 located below the valve head 1204 tilts up, and the valve head 1204 is lifted up like a seesaw, so that the lower end of the valve head 1204 is separated from the exhaust passage 1201, so that the high pressure gas in the inner pot 2 is discharged through the exhaust passage 1201. A spring is arranged below the pressing block 1203 to reset the spring, and at this time the valve head 1204 will also descend under the action of gravity and be reinserted into the exhaust passage 1201 for sealing.

[0048] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
