Description

Technical Field

[0001] The utility model relates to the technical field related to small household appliances, in particular to a pot cover assembly and also to a pot with multiple cooking modes. Background Art

[0002] Currently, electric rice cookers and pressure cookers offer a single function: Electric pressure cookers can only operate in high-pressure mode. This utilizes the principle that the boiling point of liquids increases under higher pressure, allowing water to reach a higher temperature without boiling, thus speeding up cooking. However, this mode prevents the rice from rolling, resulting in poor cooking results; and electric rice cookers can only operate in normal-pressure mode, resulting in low cooking efficiency. To avoid the need for users to purchase both an electric pressure cooker and a rice cooker, manufacturers have installed a pressure-limiting valve on the lid of the electric pressure cooker. This valve limits the pressure inside the cooker to a higher pressure during pressure cooking. To switch the electric pressure cooker to a pressure-free state, the valve is lifted to connect the cooker to the outside world.

[0003] To achieve the switch between pressurized and unpressurized states, the prior art proposes a variety of implementation methods. For example, Chinese patent CN217592544U employs a lever and a shift block, with the shift block and a pressure-limiting valve located at either end of the lever. Sliding the shift block squeezes or releases one end of the lever to achieve the switch between pressurized and unpressurized. For example, Chinese patent CN2168227940 employs a lever and a knob, with the knob and a pressure-limiting valve located at either end of the lever. Rotating the switching knob drives one end of the lever, thereby raising or lowering the other end, raising or resetting the pressure-limiting valve, thereby achieving the switch between pressurized and unpressurized states. Whether driven by sliding or rotating, the operating end (dial or knob) and the operated end (pressure limiting valve) are located at both ends of the lever fulcrum and there is a long distance between the operating end and the operated end. With such a design, at least two installation positions need to be opened on the cover body during processing and molding, one for installing the pressure limiting valve and the other for installing the operating dial or knob. This structure is relatively complex, and for manufacturers, the processing difficulty and cost increase. Utility Model Content

[0004] In order to overcome the existing technical defects, the purpose of the present invention is to provide a pot cover assembly to solve the above technical problems.

[0005] The technical solutions adopted by the present invention to solve the technical problems are as follows:

[0006] According to one aspect of the utility model, a pot cover assembly is designed, comprising: a cover body and a valve body arranged above the exhaust valve core on the cover body, characterized in that a dial knob that can move up and down along the exhaust valve core is provided under the valve body, and a buckle on the dial knob is movably arranged in a rotating hole on the cover body, and a reset elastic member elastically abutting against the dial knob and the cover body is provided between the dial knob and the cover body, and a first step and a second step are provided on the side wall of the rotating hole. When the rotating dial knob is linked to the buckle to move to the first step position, the valve body is pressed on the top of the exhaust valve core by gravity. When the rotating dial knob is linked to the buckle to move to the second step position, the dial knob moves upward and drives the valve body to move upward so that a gap is maintained between the top cone on the valve body and the exhaust valve core.

[0007] By adopting the above technical solution, a reset elastic member is set between the knob and the cover body to elastically abut against both. When the knob is rotated to move to the first step position in conjunction with the buckle, the reset elastic member can keep the buckle in the first step position. When the knob is rotated to move to the second step position in conjunction with the buckle, the reset elastic member can keep the buckle in the second step position, thereby realizing pressure mode switching. Compared with the existing method of driving one end of the lever to drive the other end of the lever to lift or fall to lift or reset the pressure limiting valve to realize pressure and no pressure switching, the present technical solution can be realized by rotating the knob in combination with the spring. It has a simple structure and is easy to process and produce for manufacturers, which can reduce processing costs.

[0008] In order to better solve the above technical defects, the present invention also has a better technical solution:

[0009] In some embodiments, a third step is provided on the side wall of the rotating hole. When the rotating knob is linked to the buckle and moved to the third step position, a magnetic attraction is generated between the first attraction member on the knob and the second attraction member on the valve body, causing the top cone on the valve body to apply pressure to the top of the exhaust valve core.

[0010] When the buckle moves to the first step position, the first attraction component is away from the second attraction component, and there is no magnetic attraction force between the first attraction component and the second attraction component.

[0011] When the knob is close to the valve body, the magnetic attraction force generated between the first suction piece on the knob and the second suction piece on the valve body can cause the top cone on the valve body to apply pressure to the top of the exhaust valve core, thereby realizing the high-pressure cooking mode. In this way, three cooking modes are realized. Compared with existing cookware, more cooking modes are realized, which well meets the cooking needs of users, and the structure is relatively simple and the production cost is low.

[0012] In some embodiments, a lever is hingedly connected to the cover body. When the rotating dial knob drives the buckle to move to the first step position, the buckle drives one end of the lever to move downward and the other end of the linkage lever to tilt up, so that the trigger member on the other end of the lever leaves the trigger position. When the rotating dial knob drives the buckle to leave the first step position, the buckle separates from the lever, and the other end of the lever moves downward and resets, driving the trigger member to reset to the trigger position.

[0013] In some embodiments, a self-locking sliding part is movably connected to the cover body, and a driving head is provided at one end of the self-locking sliding part and a lug is provided at the other end. An elastic driving part is provided in the cover body, with one end elastically abutting against the self-locking sliding part and the other end elastically abutting against the self-locking sliding part. The lug is inserted into the rotating hole and is located on one side of the second step. The lug is used to drive the buckle to move from the second step to the third step, so that the knob returns to the high-pressure mode.

[0014] In some embodiments, one of the first attraction member and the second attraction member is a magnetic block or an electromagnet, and the other is a magnetic block or an iron block or an iron alloy block or a nickel alloy block.

[0015] In some embodiments, a dial head is provided on the outside of the dial member, and a cover is connected to the top. A through hole is provided on the top of the cover. The reset elastic member is a spring or a spring. The upper end of the exhaust valve core is inserted into the valve body, and the valve body and the exhaust valve core are movably coordinated up and down.

[0016] In some embodiments, the cover body includes an outer shell, an inner lining connected to the outer shell, and a bracket installed between the outer shell and the inner lining. A frustum is provided on the outer shell, a groove and an annular groove are provided on the top of the frustum, the lower end of the knob is inserted into the groove, the annular portion on the knob is inserted into the annular groove, the buckle is connected to the annular portion, the rotating hole is provided on the frustum, the lever is hinged to the bracket, and the self-locking sliding part is laterally movable with the bracket.

[0017] In some embodiments, the elastic driving member is a spring, the self-locking sliding member is connected to a guide column, the guide column is laterally movably engaged with a through hole on the bracket, and the spring is sleeved on the guide column.

[0018] In some embodiments, the triggering member is a magnet block.

[0019] According to another aspect of the present invention, a cookware with multiple cooking modes is designed, comprising: a pot body, an inner pot disposed within the pot body, and the aforementioned lid body, wherein the lid body is rotatably opened and closed and covers the pot body, the pot body is provided with a driving protrusion, and a magnetic induction switch for detecting whether a trigger assembly of a trigger member on the lid body is in a trigger position, the magnetic induction switch being electrically connected to a control circuit board on the pot body, and when the lid body and the pot body are rotated to open and close, the driving protrusion can drive a driving head to drive a self-locking sliding member to move a linkage lug driving buckle from a second step to a third step. Thus, when the lid body and the pot body are rotated to close or open, the valve body can be automatically driven to a high-pressure position, preventing the user from forgetting to reset the high-pressure state after venting, resulting in a pressure-free state during secondary use and causing the pot to overflow.

[0038] Example 1

[0039] refer to Figures 1 to 13As shown, the utility model provides a pot cover assembly, comprising: a cover body 1 and a valve body 2, a degassing valve core 10 is provided on the top of the cover body 1, and the valve body 2 is provided above the degassing valve core 10. Further, the upper end of the degassing valve core 10 is inserted into the valve body 2, and the valve body 2 and the degassing valve core 10 are movably cooperated up and down, and a dial knob 3 that can move up and down along the degassing valve core 10 is provided under the valve body 2, and one, two or three clips 31 are provided on the dial knob 3. In this embodiment, preferably, two clips 31 are provided on the dial knob 3, and a dial head 32 is provided on the outside of the dial knob 3, which is convenient for tossing the dial knob 3 to rotate. A cover shell 33 is connected to the top of the dial knob 3, and the cover shell 33 is snapped or threadedly connected to the dial knob 3 or fixed by screws. In this embodiment, preferably, the cover shell 33 is snapped with the dial knob 3, and a through hole is provided on the top of the cover 33, and the valve body 2 is wrapped inside by the cover shell 33 and the dial knob 3.

[0040] A first suction member 34 is connected to the bottom of the knob 3, and a second suction member 21 is provided at the lower end of the valve body 2. When the first suction member 34 and the second suction member 21 are close to each other, they can be attracted by magnetic force. When the distance between the two is far, the suction force between the two can be ignored, and it is regarded as that there is no magnetic attraction between the two. Among them, one of the first suction member 34 and the second suction member 21 is a magnetic block or an electromagnet, and the other is a magnetic block or an iron block or an iron alloy block or a nickel alloy block, etc. In this embodiment, preferably, the first suction member 34 and the second suction member 21 are both magnetic blocks, and a magnetic block is provided at the bottom of the valve body 2 to form a magnetic valve.

[0041] The cover body 1 is provided with rotating holes 1100, and the number of rotating holes 1100 is the same as the number of buckles 31. The two buckles 31 on the dial knob 3 are correspondingly and movably arranged in the two rotating holes 1100 on the cover body 1. A reset elastic member 4 is provided between the dial knob 3 and the cover body 1. The lower end of the reset elastic member 4 is elastically abutted against the cover body 1, and the upper end is elastically abutted against the dial knob 3. The reset elastic member 4 is a spring or a spring sheet. In this embodiment, the reset elastic member 4 is preferably a spring.

[0042] A lever 14 is provided within the cover 1 and is hingedly connected to the cover 1. The left end of the lever 14 is located on one side of a rotating hole 1100 thereof, and the right end of the lever 14 is connected to a trigger 15, which is a magnet. A first step 1101, a second step 1102, and a third step 1103 are provided at the top of the rotating hole 1100. The second step 1102 is higher than the third step 1103, and the third step 1103 is higher than the first step 1101. The resetting elastic member 4 allows the top surface of the buckle 31 to abut against the first step 1101, the second step 1102, and the third step 1103, respectively, and to remain in the first step 1101, the second step 1102, and the third step 1103, respectively. Rotating the dial 3 allows the buckle 31 to freely change positions among the first step 1101, the second step 1102, and the third step 1103 through the rotating hole 1100.

[0043] The cover body 1 includes an outer shell 11, an inner lining 12 connected to the outer shell 11, and a bracket 13 installed between the outer shell 11 and the inner lining 12. A cone 110 is provided on the outer shell 11, and a groove 1104 and an annular groove 1105 are provided on the top of the cone 110. The lower end of the knob 3 is inserted into the groove 1104, and the annular portion 35 on the knob 3 is inserted into the annular groove 1105. The buckle 31 is connected to the annular portion 35, and the buckle 31 and the annular portion 35 are an integral structure. The rotating hole 1100 is provided on the cone 110, the hinge column on the lever 14 is hinged to the bracket 13, and the reset elastic member 4 is located in the groove 1104.

[0044] When the rotating dial knob 3 drives the buckle 31 to move to the first step 1101 position, the valve body 2 is pressed on the top of the exhaust valve core 10 by gravity, that is, the top cone 22 on the valve body 2 is pressed on the top of the exhaust valve core 10. The valve body 2 has a lightweight structure, that is, it is light in weight. The lower end of the top cone 22 blocks the exhaust channel on the exhaust valve core 10. At this time, the first suction member 34 is away from the second suction member 21, that is, the distance between the first suction member 34 and the second suction member 21 is far, and the suction force between the two is negligible. When the lid 1 and the pot 7 are cooked together, the interior of the pot can be in a micro-pressure state, and the micro-pressure cooking mode is performed. During the cooking process, when the pressure inside the pot increases, the valve body 2 can be lifted up to exhaust the gas, so that the interior of the pot is always kept in a micro-pressure state; when the rotary knob 3 is rotated to drive the buckle 31 to move to the second step 1102 position, the knob 3 moves upward to contact the valve body 2 and drive the valve body 2 to move upward, so that a gap is maintained between the top cone 22 on the valve body 2 and the exhaust valve core 10. When the lid 1 and the pot 7 are cooked together, the interior of the pot 7 is connected to the outside through the channel on the exhaust valve core 10 and the gap between the top cone 22 and the exhaust valve core 10, and the pressure-free cooking mode can be performed; when the rotary knob 3 is rotated to move to the third step 1103 position, the knob 3 moves upward to contact the valve body 2 and drive the valve body 2 to move upward, so that a gap is maintained between the top cone 22 on the valve body 2 and the exhaust valve core 10. , the dial knob 3 contacts the valve body 2 or maintains a small gap, and a magnetic attraction force is generated between the first suction piece 34 on the dial knob 3 and the second suction piece 21 on the valve body 2, so that the top cone 22 on the valve body 2 applies pressure to the top of the exhaust valve core 10. When the lid body 1 and the pot body 7 are matched for cooking, the high-pressure cooking mode can be achieved by applying pressure to the top of the exhaust valve core 10 through the top cone 22. If the internal pressure of the pot is too high during cooking, the valve body 2 can be lifted up to exhaust the air, so that the set high pressure state is always maintained in the pot.

[0045] A self-locking slide 5 is movably connected in the cover body 1. Further, the self-locking slide 5 is laterally movably matched with the bracket 13. A driving head 51 is provided at the lower end of the self-locking slide 5. The driving head 51 passes through the through hole on the lining 12 and extends to the inside of the lining 12. A lug 52 is provided at the upper end of the self-locking slide 5. An elastic driving member 6 is provided in the cover body 1. Specifically, a mounting groove is provided on the bracket 13. The self-locking slide 5 is connected to a guide column 53. The right end of the guide column 53 is laterally movably connected to the through hole on the bracket 13. Dynamic fit, the elastic driving member 6 is a spring, which is arranged in the installation groove and sleeved on the guide column 53. One end of the spring elastically abuts against the side wall of the installation groove on the bracket 13, and the other end elastically abuts against the self-locking sliding member 5. The lug 52 is inserted into the rotating hole 1100 and is located on the side of the second step 1102. When the driving head 51 is forced to move toward the inside of the cover body 1, it can drive the self-locking sliding member 5 to move and the lug 52 drives the buckle 31 to move from the second step 1102 to the third step 1103. Figure 12The arrow in the figure indicates the moving direction of the driving head 51 after the force is applied, that is, it moves to the right. When the force disappears, the elastic driving member 6 drives the self-locking sliding member 5 to move left and reset.

[0046] Example 2

[0047] refer to Figures 1 to 13 As shown, the utility model provides a cookware with multiple cooking modes, comprising a pot body 7, an inner pot 8 arranged in the pot body 7 and a lid body 1 in embodiment 1. The lid body 1 is rotatably opened and closed and covers the pot body 7. A driving protrusion 71 is provided on the pot body 7, and a magnetic induction switch for detecting whether the trigger member 15 on the lid body 1 is in the trigger position. The magnetic induction switch is electrically connected to the control circuit board on the pot body 7. When the magnetic induction switch detects that the trigger member 15 is not in the trigger position, it feeds back information to the control circuit board. The control circuit board controls micro-pressure cooking and controls the firepower by a program to avoid overflowing caused by high-fire heating. When the lid body 1 and the pot body 7 are rotated to open and close, that is, when the lid body 1 and the pot body 7 are rotated to cover or rotated to open, the driving protrusion 71 can drive the driving head 51 to move toward the inside of the lid body 1, driving the self-locking sliding member 5 to move, and the linked lug 52 drives the buckle 31 to move from the second step 1102 to the third step 1103.

[0048] The above are only some embodiments of the present invention. For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
