[0027] References in this specification to "one embodiment" or "an example" or "an example" mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment of the present patent disclosure. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0028] Example:

[0029] like Figures 1 to 3As shown, a pressure cooker is provided in this embodiment, comprising a pot body 2 and a cover body 1 rotatably buckled on the pot body 2, a cover handle 12 being arranged on the cover body 1, a pot handle 22 docking with the cover handle 12 being arranged on the pot body 2, a locking groove 221 being provided on the pot handle 22, the cover handle 12 comprising a locking push knob 121 at least partially extending into the locking groove 221; the locking groove 221 comprising an unlocking section 2211 and a locking section 2212, when the locking push knob 121 is located at the unlocking section 2211, the cover body 1 can rotate relative to the pot body 2, when the locking push knob 121 is located at the locking section 2212, the cover body 1 is locked on the pot body 2; the pressure cooker further comprises a button 122 cooperating with the locking push knob 121, the button 122 can drive the locking push knob 121 to move from the locking section 2212 to the unlocking section 2211.

[0030] In this embodiment, the pressure cooker is composed of a pot body 2 and a cover body 1. The pot body 2 is provided with a pot tooth 21, and the cover body 1 is provided with a cover tooth 11. The cover tooth 11 and the pot tooth 21 are locked or unlocked on the body by rotating and buckling. The pot body 2 is provided with a pot handle 22 for holding and moving the pot body 2, and the cover body 1 is provided with a cover handle 12 for holding and rotating the cover body 1 to buckle with or separate from the pot body 2. In addition, a locking groove 221 is provided on the pot handle 22, and the locking groove 221 can be divided into an unlocking section 2211 and a locking section 2212; a locking push knob 121 is provided on the cover handle 12. In this embodiment, the locking push knob 121 partially extends into the locking groove 221 of the pot handle 22, and in other embodiments, the locking push knob 121 can also be fully extended into the locking groove 221 of the pot handle 22. When the locking push knob 121 is located at the unlocking section 2211, the user can easily rotate the cover body 1 so that the cover teeth 11 and the pot teeth 21 are engaged or separated. When the locking push knob 121 is pushed into the locking section 2212, the cover body 1 cannot rotate and is locked on the pot body 2 to prevent accidental opening. Specifically, a button 122 that cooperates with the locking push knob 121 is also provided on the cover handle 12. The user drives the locking push knob 121 to move from the locking section 2212 to the unlocking section 2211 by operating the button 122, thereby conveniently and quickly unlocking the cover body 1. In other embodiments, the button 122 can also be set on the pot handle 22, which is not limited here. The pressure cooker of this embodiment can realize the unlocking of the cover body 1 through the cooperation of the locking push knob 121, the locking groove 221 and the button 122. The structure is simple and easy to install, which not only reduces the production cost, but also reduces the probability of failure and improves the reliability and durability of the pressure cooker. In this embodiment, the user drives the locking knob 121 to move linearly by pressing the button 122. In other embodiments, the user can also set components such as gears to cooperate with the button 122 to drive the locking knob 121 by rotating the button 122, which will not be repeated here.

[0031] A stopper 2213 protruding toward the interior of the locking groove 221 is formed in the locking groove 221 , and the stopper 2213 divides the locking groove 221 into a locking section 2212 and an unlocking section 2211 .

[0032] In this embodiment, a stopper 2213 protruding toward the inside of the locking groove 221 is formed to divide the locking groove 221 into a locking section 2212 and an unlocking section 2211. When the locking push knob 121 is pushed into the locking section 2212, the stopper 2213 can prevent the locking push knob 121 from easily sliding out of the locking section 2212, thereby locking the cover body 1. The user can drive the locking push knob 121 to move from the locking section 2212 to the unlocking section 2211 by operating the button 122, and the stopper 2213 also plays a role in guiding the movement trajectory of the push knob. Specifically, the user presses the button 122 on the cover handle 12, and the button 122 drives the locking push knob 121 to move from the locking section 2212 to the unlocking section 2211. The user can easily rotate the cover body 1 to make the cover teeth 11 engage or disengage with the pot teeth 21, thereby conveniently opening or closing the pressure cooker. When the user does not press the button 122, the block 2213 restricts the locking push knob 121 from entering the unlocking section 2211 from the locking section 2212, thereby ensuring the safety of the pressure cooker.

[0033] The unlocking section 2211 is formed with an arc-shaped side wall 2211 a which gradually moves away from the cover body 1 in a direction away from the locking section 2212 .

[0034] In this embodiment, when the locking push knob 121 is located in the unlocking section 2211, the user rotates the cover body 1 to separate or engage the cover teeth 11 and the pot teeth 21, and the arc-shaped side wall 2211a formed by the unlocking section 2211 makes the movement track of the locking push knob 121 match the movement track of the cover body 1, thereby improving the smoothness of the rotation of the cover body 1 and the user experience. In addition, due to the presence of the arc-shaped side wall 2211a, even in the case of incomplete alignment, the push knob is unlikely to accidentally slide into the locking section 2212, thereby avoiding an accidental locking state and increasing the safety of the user during operation.

[0035] The opening direction of the locking section 2212 is perpendicular to the opening direction of the unlocking section 2211 .

[0036] In this embodiment, the locking groove 221 includes a locking section 2212 opened horizontally and an unlocking section 2211 opened vertically. After the locking push knob 121 enters the horizontal locking section 2212, it is not easy to slide into the vertical unlocking section 2211. The push knob can stay in the locking position more firmly, preventing accidental unlocking due to external force or vibration, and ensuring the safety of the pressure cooker. In addition, the opening direction of the locking section 2212 is perpendicular to the opening direction of the unlocking section 2211, which further increases the difficulty of the locking push knob 121 entering the unlocking section 2211, and enhances the safety and stability of the locking mechanism.

[0037] like Figure 4 As shown, a first inclined surface 1221 is formed on the button 122, and a second inclined surface 1211 matching the first inclined surface 1221 is formed on the locking push knob 121. When the button 122 moves toward the locking push knob 121, the first inclined surface 1221 and the second inclined surface 1211 abut against each other to drive the locking push knob 121 to move from the locking section 2212 to the unlocking section 2211.

[0038] In this embodiment, a first inclined surface 1221 is formed on the button 122, and a second inclined surface 1211 is correspondingly formed on the locking push knob 121. The first inclined surface 1221 and the second inclined surface 1211 abut against each other when the button 122 moves toward the locking push knob 121, thereby realizing the movement of the locking push knob 121. When the user presses the button 122, the first inclined surface 1221 contacts and applies pressure to the second inclined surface 1211. Due to the design of the inclined surface, the pressure is converted into a force that pushes the locking push knob 121 to move toward the unlocking section 2211. Through the cooperation of the inclined surfaces, the user only needs to press the button 122 to realize unlocking, without using other tools or performing complicated operations, which greatly improves the convenience of use.

[0039] like Figure 5 As shown, a guide column 1212 is provided on the locking push button 121 , and a guide groove 1222 cooperating with the guide column 1212 is opened on the surface of the button 122 , and the opening direction of the guide groove 1222 is consistent with the inclination direction of the first inclined surface 1221 .

[0040] In this embodiment, the cooperation between the guide column 1212 and the guide groove 1222 ensures the stability of the locking push knob 121 during the movement, and avoids the displacement of the parts during the movement. Since the opening direction of the guide groove 1222 is consistent with the inclination direction of the first inclined surface 1221, the entire unlocking process is smoother and more fluent, reducing the resistance and uncertainty of the user's operation. At the same time, it also makes the locking and unlocking mechanism more compact, does not increase the additional space requirements, and improves the overall aesthetics of the product.

[0041] The cover handle 12 includes a shell 123 , in which a straight groove 1231 adapted to the locking push button 121 is opened. The opening direction of the straight groove 1231 is consistent with the opening direction of the locking section 2212 .

[0042] In this embodiment, a straight groove 1231 adapted to the locking push knob 121 is provided in the housing 123. The straight groove 1231 is used to accommodate and guide the movement of the locking push knob 121. The opening direction of the straight groove 1231 is consistent with the opening direction of the locking section 2212. When the locking push knob 121 moves in the groove, it will directly move along the path of the locking section 2212, ensuring the accuracy and stability of the operation. It should be noted that the width of the straight groove is consistent with the width of the portion of the locking push knob 121 located in the straight groove, that is, the portion of the locking push knob 121 located in the straight groove is just embedded in the straight groove to prevent the locking push knob 121 from shaking easily.

[0043] like Figure 6 As shown, a clearance groove 1213 is formed on the locking push knob 121, and a protrusion 1213a and a first spring 1213b that keeps the protrusion 1213a protruding from the outer wall surface of the locking push knob 121 are installed in the clearance groove 1213.

[0044] In this embodiment, a clearance groove 1213 for installing a protrusion 1213a and a first spring 1213b is formed on the locking push knob 121. The first spring 1213b keeps the protrusion 1213a in a state of protruding from the outer wall surface of the locking push knob 121. It should be noted that the protrusion 1213a can also be completely received in the clearance groove 1213 under the action of external force to avoid affecting the locking push knob 121 in the straight groove 1231 due to being restricted by the protrusion 1213a and being unable to move.

[0045] like Figure 6 As shown, a positioning pin 222 is formed on the pot handle 22 to cooperate with the locking push knob 121, and a second spring 13 is arranged between the side wall of the cover body 1 and the locking push knob 121. When the positioning pin 222 pushes against the protrusion 1213a, the locking push knob 121 can move freely in the straight groove 1231 under the action of the second spring 13.

[0046] In this embodiment, when the positioning pin 222 pushes against the projection 1213a, the projection 1213a will be forced into the clearance groove 1213, and the first spring 1213b will be compressed, and the locking push knob 121 is in a movable state. After the projection 1213a is received in the clearance groove 1213, the second spring 13 between the side wall of the cover body 1 and the locking push knob 121 can push the locking push knob 121 from the end of the unlocking section 2211 to the locking section 2212 in the horizontal direction, thereby achieving stable locking of the cover body 1. The positioning pin 222 is used to position the locking push knob 121 so that the locking push knob 121 accurately enters the locking section 2212. When the locking push knob 121 is not rotated to the appropriate position (i.e., the position abutting against the positioning pin 222), the projection 1213a still protrudes from the outer wall of the locking push knob 121, and the locking push knob 121 cannot enter the locking section 2212.

[0047] A safety valve 14 is provided on the cover body 1. The safety valve 14 includes a valve stem 141 that can rise and fall with pressure changes. A locking groove 1214 that cooperates with the valve stem 141 is formed on the side of the locking knob 121 facing the valve stem 141 to prevent the locking knob 121 from moving.

[0048] In this embodiment, the safety valve 14 includes a valve stem 141 that can be raised and lowered with pressure changes. When the pressure in the pot body 2 rises to a preset value, the valve stem 141 will be lifted up to release the excess pressure. The locking push knob 121 is formed with a clamping groove 1214 that cooperates with the valve stem 141 on one side of the valve stem 141. The function of this clamping groove 1214 is that when the safety valve 14 is in an open state (i.e., the valve stem 141 is lifted up), through the cooperation between the clamping groove 1214 and the valve stem 141, even if the user presses the button 122, the locking push knob 121 cannot be moved, thereby ensuring that the pot cover cannot be unlocked when the pressure is too high, avoiding the danger caused by the user opening the pot cover with too high pressure without knowing it. Only when the pressure in the pot is reduced to below the safety value and the valve stem 141 falls back to the original position, the user can move the locking push knob 121 by operating the button 122 and other mechanisms to unlock the pot cover.

[0049] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention shall be included in the scope of the claims.
