Description

Technical Field

[0001] The utility model is applied to the technical field of pressure cookers, and particularly relates to a full-rotation clamp-type pressure cooker. Background Art

[0002] In daily life, various kitchen utensils are used to prepare food, such as rice cookers, ovens, microwave ovens, etc. Due to the different altitudes in different regions, the air pressure in high altitude areas is lower and the boiling point of water is lower. During the cooking process, the water temperature cannot cook the food, and a pressure cooker is needed to pressurize the water to increase the boiling point of the water and thus speed up the cooking of the food. Traditional pressure cookers slide the slots between the pot body and the lid against each other to press the whole thing closed. For the sake of sealing, the fit of the slots between the pot body and the lid is very tight and the tightness cannot be adjusted. A large force is required to rotate during the locking and unlocking process. For operators with less strength, the pot cannot be opened or locked, and it is difficult to control the balance of the pot body during the opening process, which can easily cause the pressure cooker to fall off, posing a high risk. At present, the lid and the pot body can be clamped together by adding a mechanical transmission knob-type clamp mechanism to the pot cover. However, since the multi-stage transmission requires more components, the overall weight of the pressure cooker is relatively large, and the handle is easily broken due to the large force applied during the transfer process of the pressure cooker. In addition, the mechanical structure of the multi-stage transmission is prone to rust in a humid environment, resulting in failure to lock normally. The sealing is not strong during the pressurization process, and the pot cover is prone to fall off. If a full-rotation clamp-type pressure cooker with a simple structure, modular design, light weight, and more uniform articulated linkage clamping force can be designed, the above problems can be solved.

[0023] like Figures 1 to 9As shown, in this embodiment, the utility model includes a pot body 1, a pot cover 2 and a full-swing clamp assembly 3, the full-swing clamp assembly 3 includes a handle 4, a knob 5 and a locking ring module 6, the handle 4 is connected to one side of the upper end surface of the pot cover 2, the locking ring module 6 includes a first locking ring 61 and a second locking ring 62, the upper end surface of the pot cover 2 away from the handle 4 is provided with a rotating pin 7, one end of the first locking ring 61 and the second locking ring 62 are respectively rotatably matched with the rotating pin 7, the knob 5 is rotatably matched with the handle 4, and the first locking ring The other ends of the first locking ring 61 and the second locking ring 62 are respectively provided with a first limit pin 63 and a second limit pin 64, the connecting part of the handle 4 is provided with a first transverse groove 41 and a second transverse groove 42, the knob 5 is provided with a first arc groove 51 and a second arc groove 52, the first limit pin 63 and the second limit pin 64 respectively pass through the first transverse groove 41 and the second transverse groove 42 and cooperate with the first arc groove 51 and the second arc groove 52, and the knob 5 drives the first locking ring 61 and the second locking ring 62 to cooperate with the pot body 1. It can be seen that the pot body 1 is locked by hingedly connecting one end of the first locking ring 61 and the second locking ring 62 to one side of the pot cover 2 and pressing and locking the other end thereof. The first arc groove 51 and the second arc groove 52 and the first transverse groove 41 and the second transverse groove 42 on the knob 5 cooperate with the first limit pin 63 and the second limit pin 63. When rotated in the unlocking direction, the first limit pin 63 and the second limit pin 63 slide on the first arc groove 51 and the second arc groove 52 respectively, guiding the first limit pin 63 and the second limit pin 63 to slide outward on the first transverse groove 41 and the second transverse groove 42, so that the first locking ring 61 and the second locking ring 62 expand outward to achieve unlocking. By rotating the knob 5 in different directions, the first locking ring 61 and the second locking ring 62 can be controlled to expand or tighten outward, thereby achieving unlocking and locking.

[0024] like Figure 6 and Figure 8 As shown, in this embodiment, the upper end surface of the connection part of the handle 4 is provided with a knob profile groove 43, the first transverse groove 41 and the second transverse groove 42 are respectively provided on both sides of the middle of the knob profile groove 43, a plurality of first baffles 44 are provided on the side of the knob profile groove 43, a plurality of second baffles 53 are provided at the lower end of the knob 5, and a plurality of the first baffles 44 and a plurality of the second baffles 53 are limitedly matched. It can be seen that a plurality of the first baffles 44 and a plurality of the second baffles 53 are interlaced with each other, and are locked with each other in the locked state, and a plurality of the first baffles 44 and a plurality of the second baffles 53 are interlaced with each other in the unlocked state and can be disassembled, which can be quickly disassembled and is safer.

[0025] like Figure 6 and Figure 8 As shown, in this embodiment, the upper end of the pot cover 2 is provided with a rotation limiting rod 8, the knob profiling groove 43 is provided with a limiting hole 45, the knob 5 is provided with a rotation limiting groove 54, and the rotation limiting rod 8 is limitedly matched with the rotation limiting groove 54 through the limiting hole 45. It can be seen that the rotation limiting rod 8 limits the handle 4 through the limiting hole 45, and can limit the rotation range of the knob 5 through the rotation limiting groove 54, so as to prevent the pot body 1 from rebounding and unlocking during the pressurization process due to overpressure.

[0026] like Figures 1 to 3 As shown, in this embodiment, the upper end surface of the pot cover 2 is provided with a relief valve 9, and the relief valve 9 is in communication with the pot body 1. It can be seen that the relief valve 9 releases pressure when the pressure is too high.

[0027] like Figures 1 to 3 As shown, in this embodiment, the handle portion of the handle 4 extends in the direction toward the rotating pin 7. It can be seen that the handle portion of the handle 4 facing inward can reduce the overall size and prevent the handle 4 from being accidentally touched during the pressurization process, causing the pressure cooker to deviate as a whole.

[0028] like Figure 5 and Figure 6 As shown, in this embodiment, a support extension block 10 is provided on the side of the handle 4 connection portion away from the handle portion, and the pot cover 2 cooperates with the external plane support platform through the support extension block 10. It can be seen that when the pot cover 2 is opened in the unlocked state, the pot cover 2 can be vertically supported on the plane support platform, so that the moisture on the pot cover 2 can flow out quickly, preventing moisture accumulation from causing bacteria to grow.

[0029] like Figures 1 to 3 As shown, in this embodiment, a safety valve 11 is further provided on the upper end of the pot cover 2, and the safety valve 11 cooperates with the pot body 1. It can be seen that the safety valve 11 provides secondary protection to prevent the pressure from being too high and the air relief valve 9 failing, and the pressure can be released normally.

[0030] like Figure 1 As shown, in this embodiment, a heat insulation protective pad 12 is provided between the pot cover 2 and the handle 4. It can be seen that the heat insulation protective pad 12 provides heat insulation and protection.

[0031] like Figure 4 As shown, in this embodiment, a protective cover 13 is provided on the upper end of the knob 5, and an anti-fool mark is provided on the upper end surface of the protective cover 13. It can be seen that the protective cover 13 can prevent external impurities from falling into the interior of the knob 5 and causing failure to lock or unlock normally, and the anti-fool mark can prevent misoperation from causing failure to lock or unlock normally.

[0032] The working principle of the utility model is as follows: food is put into the pot body 1, the pot cover 2 is placed on the upper end of the pot body 1, and the knob 5 is rotated to make the first limit pin 63 and the second limit pin 64 slide on the first arc groove 51 and the second arc groove 52 respectively, and the first limit pin 63 and the second limit pin 64 move towards each other on the first transverse groove 41 and the second transverse groove 42 respectively, so that the first locking ring 61 and the second locking ring 62 are close to each other and press the pot body 1, and heating is performed after locking is completed, and the pressure in the pot body 1 increases. After the pressurization is completed, the pressure is released through the air relief valve 9, and after the pressure release is completed, the knob 5 is reversed, and the first limit pin 63 and the second limit pin 64 slide back and forth on the first transverse groove 41 and the second transverse groove 42 respectively, and the first locking ring 61 and the second locking ring 62 are separated from each other to achieve unlocking, thereby realizing the full-rotation clamp-type locking and unlocking of the pressure cooker.

[0033] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
