Technical Field
[0001] The utility model is applied to the technical field of pressure cookers, and particularly relates to a clamp type pressure cooker. Background Art
[0002] A pressure cooker, also known as a pressure pot, is a commonly used cooking tool in the kitchen. In high-altitude areas, the boiling point of water is relatively low, and traditional cookware cannot effectively cook food. In this case, a pressure cooker needs to be used for pressure cooking. A pressure cooker makes use of the physical phenomenon that the boiling point of a liquid increases under higher air pressure, enabling water to reach a higher temperature without boiling, thereby accelerating the efficiency of stewing food. With a pressure cooker, the temperature of water can be easily heated above 100°C, effectively cooking the food. Currently, the common pressure cookers on the market are mainly of the lid screw-on type, which achieves a sealing effect by rotating and clamping the buckle on the lid with the locking block on the edge of the pot body. For this traditional pressure cooker, since the buckle and the locking block need to slide relative to each other through an inclined plane for rotational locking, to ensure the sealing performance, the buckle and the locking block need to be connected in place. However, due to the relatively large friction force between the buckle and the locking block, a relatively large force is required during the rotational locking process, which is not suitable for operators with relatively small strength. At the same time, after cooking, it is very difficult to open the lid due to the large clamping force. Additionally, due to the relatively large weight of the pot body, the force application points of the double-handle locking method are uneven, and it is easy to cause the pot to slip out of the hand during operation. If a clamp type pressure cooker with a simple structure, good sealing performance, a combination of a knob and a handle, and an effective reduction in the risk of accidental touch can be designed, the above problems can be solved. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a clamp type pressure cooker with a simple structure, good sealing performance, a combination of a knob and a handle, and an effective reduction in the risk of accidental touch.
[0004] The technical solution adopted by the utility model is as follows: The utility model includes a pot body, a lid, and a rotary clamp module. The rotary clamp module is arranged at the upper end of the lid. The rotary clamp module includes a knob, a knob mounting seat, a push plate, and a clamp. The knob mounting seat is arranged in the middle of the upper end surface of the lid. A knob mounting groove is arranged in the middle of the upper end surface of the knob mounting seat. The knob is connected to the middle of the knob mounting groove through a positioning screw. Transverse sliding grooves are arranged on both sides of the middle of the knob mounting groove. An arc-shaped sliding groove is arranged in the middle of the knob, which is matched with the two groups of transverse sliding grooves. Two groups of push plates are arranged at the lower end of the knob mounting seat. Slide bars are arranged at the ends of the two groups of push plates close to each other. The slide bars are matched with the arc-shaped sliding groove through the transverse sliding grooves. Two groups of clamps are respectively connected to the ends of the two groups of push plates away from each other. Rotating the knob causes the two groups of clamps to clamp or loosen the pot body.
[0005] Further, a push plate sliding groove is provided in the middle of the upper end surface of the pot lid, and the two groups of push plates are slidably matched with the push plate sliding groove.
[0006] Further, locking and limiting posts are provided at both ends of the push plate sliding groove, limiting sliding grooves are provided at the mutually remote ends of the two groups of push plates, and the limiting sliding grooves and the limiting posts are in limiting cooperation.
[0007] Further, locking holes are provided at both ends of the knob mounting seat, and the locking holes and the locking and limiting posts are connected by locking screws.
[0008] Further, the outer edges on both sides of the short side of the knob are provided as arc surfaces, and the arc surfaces on both sides of the short side of the knob are in profile matching with the arc stepped surfaces at the edges of the knob mounting groove.
[0009] Further, handle grooves are provided on both sides of the long side of the knob. When in the locked state, the edges of the highest points of the handle grooves are flush with both sides of the knob mounting groove. When in the unlocked state, a grasping space is formed between the handle grooves and the arc stepped surfaces at the edges of the knob mounting groove.
[0010] Further, a floating locking module is provided at one end of the knob mounting seat, and the floating locking module is matched with the pot body and the push plate.
[0011] Further, a high-pressure air release valve is provided on the pot lid, and the high-pressure air release valve is matched with the pot body.
[0012] Further, a safety valve is also provided on the pot lid, and the safety valve is matched with the pot body.
[0013] Further, a knob protection cover is provided at the upper end of the knob.
[0014] The beneficial effects of the present utility model are as follows: when the knob is in the open state, the pot lid can be easily opened through the handle grooves on both sides of the long side of the knob. When closing the pot lid, the lower end of the clamp corresponds to the locking block at the upper end of the pot body. When the knob is rotated by 90°, the two sides of the long side of the knob correspond to both sides of the knob mounting groove, and the two groups of clamps can move towards each other, simultaneously clamping the pot lid and the pot body to achieve a sealing effect. The floating locking module is cooperated to prevent rotation and opening during the pressurization process. Moreover, the overall protrusion of the knob is small, and it is not easy to cause accidental touch during the operation process, which can effectively save space. And the unlocking during the lid-opening process can be achieved only by rotating the knob, with a simple structure and convenient operation. Description of the Drawings

[0022] As Figures 1 to 7 shown, in this embodiment, the present utility model includes a pot body 1, a pot lid 2 and a rotary clamp module 3. The rotary clamp module 3 is arranged at the upper end of the pot lid 2. The rotary clamp module 3 includes a knob 4, a knob mounting seat 5, a push plate 6 and a clamp 7. The knob mounting seat 5 is arranged in the middle of the upper end surface of the pot lid 2. A knob mounting groove 8 is arranged in the middle of the upper end surface of the knob mounting seat 5. The knob 4 is connected to the middle of the knob mounting groove 8 through a positioning screw 9. Transverse sliding grooves 10 are arranged on both sides of the middle of the knob mounting groove 8. An arc-shaped sliding groove 11 that cooperates with the two transverse sliding grooves 10 is arranged in the middle of the knob 4. Two push plates 6 are arranged at the lower end of the knob mounting seat 5. Sliding rods 12 are arranged at the ends of the two push plates 6 close to each other. The sliding rods 12 cooperate with the arc-shaped sliding groove 11 through the transverse sliding grooves 10. Two clamps 7 are respectively connected to the ends of the two push plates 6 away from each other. Rotating the knob 4 makes the two clamps 7 clamp or loosen the pot body 1. Thus, it can be seen that the knob 4 rotates and fits in the middle of the knob mounting seat 5. By rotating through the two arc-shaped sliding grooves 11, the sliding rods 2 on the two push plates 6 move horizontally on the two transverse sliding grooves 10, so as to control the two push plates 6 to approach or separate from each other, so that the two clamps 7 achieve the functions of clamping and loosening. The structure is simple, the operation is convenient, and the overall volume occupied is smaller.
[0023] As Figure 3 and Figure 6 shown, in this embodiment, a push plate sliding groove 13 is arranged in the middle of the upper end surface of the pot lid 2. The two push plates 6 are slidably matched with the push plate sliding groove 13. Thus, it can be seen that the push plate sliding groove 13 prevents the two push plates 6 from shifting during the sliding process.
[0024] As Figure 6 andFigure 7 As shown, in this embodiment, locking and limiting posts 14 are provided at both ends of the push plate sliding groove 13. Limiting sliding grooves 15 are provided at the mutually remote ends of the two groups of push plates 6, and the limiting sliding grooves 15 and the limiting posts 14 are in limiting cooperation. Thus, it can be seen that the cooperation between the limiting sliding grooves 15 and the limiting posts 14 can prevent the push plate 6 from shifting during the sliding process.
[0025] As Figure 3 and Figure 5 shown, in this embodiment, locking holes 16 are provided at both ends of the knob mounting base 5, and the locking holes 16 and the locking and limiting posts 14 are connected by locking screws. Thus, it can be seen that the knob mounting base 5 is fixedly connected to the pot lid 2 through a plurality of the locking holes 16 and a plurality of the locking and limiting posts 14.
[0026] As Figure 4 and Figure 5 shown, in this embodiment, the outer edges on both sides of the short side of the knob 4 are arc surfaces, and the arc surfaces on both sides of the short side of the knob 4 are in profiling cooperation with the arc stepped surfaces at the edges of the knob mounting groove 8. Thus, it can be seen that the arc surface design can make the rotational frictional force smaller and the rotation easier.
[0027] As Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, in this embodiment, handle grooves 17 are provided on both sides of the long side of the knob 4. When in the locked state, the edge of the highest point of the handle groove 17 is flush with both sides of the knob mounting groove 8. When in the unlocked state, a grasping space is formed between the handle groove 17 and the arc stepped surface at the edge of the knob mounting groove 8. Thus, it can be seen that when the knob 4 is rotationally locked, the long side of the knob 4 is flush with the edge of the knob mounting base 5, which can effectively prevent misoperation. After rotationally unlocking, the pot lid 2 can be directly opened through the handle groove 17, with a small occupied area and simple operation.
[0028] As Figure 5 and Figure 6 shown, in this embodiment, a floating locking module 18 is provided at one end of the knob mounting base 5, and the floating locking module 18 cooperates with the pot body 1 and the push plate 6. Thus, it can be seen that when the pressure in the pot body 1 exceeds the limit value of the floating locking module 18, the floating end of the floating locking module 18 rises and cooperates with the limiting opening on the limiting sliding groove 15, so that the push plate 6 cannot be pushed open laterally, thereby preventing the knob 4 from automatically unlocking.
[0029] As Figure 1 and Figure 2 As shown, in this embodiment, the pot lid 2 is provided with a high-pressure air release valve 19, and the high-pressure air release valve 19 cooperates with the pot body 1. Thus, it can be seen that the high-pressure air release valve 19 can release pressure when the pressure inside the pot body 1 is relatively high.
[0030] As Figure 1 and Figure 2 shown, in this embodiment, the pot lid 2 is further provided with a safety valve 20, and the safety valve 20 cooperates with the pot body 1. Thus, it can be seen that the safety valve 20 plays an insurance role when the high-pressure air release valve 19 fails.
[0031] As Figure 1 shown, in this embodiment, a knob protection cover 21 is provided at the upper end of the knob 4. Thus, it can be seen that the knob protection cover 21 can protect the internal rotating structure of the knob 4 and facilitate subsequent cleaning and maintenance.
[0032] The working principle of the present utility model: When the pot lid 2 is in the open state, materials are loaded into the pot body 1. Hold the knob 4 and place the pot lid 2 on the upper end of the pot body 1. When the two sets of clamps 7 are normally corresponding to the locking blocks on the upper end of the pot body 1, rotate the knob 4. The arc-shaped sliding groove 11 and the horizontal sliding groove 10 drive the two sets of push plates 6 to move horizontally and approach each other, and make the two sets of clamps 7 contact the pot lid 2 and the pot body 1 and clamp the pot lid 2 and the pot body 1. When the knob 4 is flush with both sides of the knob mounting seat 5, the locking is completed. Heat the pot body 1, the pressure inside the pot body 1 increases, and the floating locking module 18 locks the knob 4. After the pressurization is completed, release the pressure through the high-pressure air release valve 19. When the pressure inside and outside the pot body 1 is relatively balanced, the floating locking module 18 is unlocked. Rotate the knob 4 in the reverse direction, and the two sets of clamps 7 are unlocked, and the pot lid 2 is opened. The pressure cooker clamp-type locking is realized through the above steps.
[0033] Although the embodiments of the present utility model are described with actual solutions, they do not constitute a limitation to the meaning of the present utility model. For those skilled in the art, the modification of its implementation solutions according to this specification and the combination with other solutions are obvious.
