Based on the embodiments in the embodiments, it is intended to explain the present application, and cannot be understood as a limitation of the present application.

[0045] In this specification, "one embodiment" or "an embodiment" or "example" or "exemplary" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. The appearances of the phrase "in one embodiment" or "an example" or "exemplary" in various places in the specification are not necessarily all referring to the same embodiment.

[0046] Referring to FIG. 1, FIG. 5, FIG. 10, one of the embodiments of the present application provides a pressure cooker, which comprises a lid 3, a pot body, the pot body comprising a pot body 1 and two handles 2 arranged on the pot body 1, the pot body 1 forming a cooking cavity; at least two through-hole assemblies 15 are arranged on the side wall of the pot body 1, wherein the same number of plug plates 34 as the through-hole assemblies 15 are arranged on the lid 3 and movably connected, one end of the plug plate 34 being capable of being inserted into the through-hole assembly 15 so that the lid 3 cannot be separated from the pot body under the action of the air pressure in the cooking cavity; a positioning assembly is arranged between at least one handle 2 and the lid 3, the handle 2 and the lid 3 being positioned by the positioning assembly so that the plug plate 34 and the through-hole assembly 15 are in the corresponding positions, a sealing element 37 being arranged on the lid, the lid 3 being buckled on the pot body to form a seal between the sealing element 37 and the inner side wall of the pot body 1, the through-hole assembly 15 being arranged between the opening end of the cooking cavity and the seal.

[0047] The positioning assembly in the embodiment comprises a positioning hole 21 and a positioning block 33, in actual arrangement, one of the handle 2 and the lid 3 is provided with the positioning hole 21, and the other is provided with the positioning block 33. As can be seen, the positioning hole 21 and the positioning block 33 are arranged on different components (the handle 2 or the lid 3), and the positioning block 33 can be inserted into the positioning hole 21 to realize the positioning of the handle 2 and the lid 3.

[0048] Referring to FIG. 2, FIG. 3, FIG. 10, one of the embodiments of the present application provides a pressure cooker, which comprises a lid 3, a pot body, the pot body comprising a pot body 1 and two handles 2 arranged on the pot body 1, the pot body 1 forming a cooking cavity; at least two through-hole assemblies 15 are arranged on the side wall of the pot body 1, wherein the same number of plug plates 34 as the through-hole assemblies 15 are arranged on the lid 3 and movably connected, one end of the plug plate 34 being capable of being inserted into the through-hole assembly 15 so that the lid 3 cannot be separated from the pot body under the action of the air pressure in the cooking cavity; a positioning assembly is arranged between at least one handle 2 and the lid 3, the handle 2 and the lid 3 being positioned by the positioning assembly so that the plug plate 34 and the through-hole assembly 15 are in the corresponding positions, a sealing element 37 being arranged on the lid, the lid 3 being buckled on the pot body to form a seal between the sealing element 37 and the inner side wall of the pot body 1, the through-hole assembly 15 being arranged between the opening end of the cooking cavity and the seal.

[0049] The plug plate 34 in the embodiment is consistent with the number of the through-hole assemblies 15 and is arranged correspondingly, one end of the plug plate 34 forming an insertion part 35 capable of being inserted into the through-hole assembly 15 with the movement of the plug plate 34, so that the lid 3 and the pot body are multi-point matched in the circumferential direction, and the stability of the connection between the lid 3 and the pot body is improved.

[0050] The cross-sectional shape of the matching position of the positioning block 33 and the positioning hole 21 in the embodiment can also be circular, rectangular, waist-shaped, triangular, trapezoidal or other forms, and a smooth transition part can also be arranged on the edge of the hole of the positioning hole 21 and the end of the positioning block 33, respectively, to facilitate the insertion of the positioning block 33 into the positioning hole 21.

[0051] The embodiment is provided with a circumferential sealing member 37 at one end of the pot cover 3. The sealing member 37 is embedded and clamped on the pot cover 3. The sealing member 37 directly contacts the inner side wall of the pot body 1. The pot cover 3 is buckled on the pot body to press the sealing member 37 against the inner wall of the pot body to achieve the sealing of the cooking cavity of the pot body.

[0052] When the pressure cooker is used, the pot cover 3 is buckled on the pot body. The positioning block 33 on the pot cover 3 is inserted into the positioning hole 21 to realize the mutual positioning of the pot cover 3 and the pot body. At this time, the position of the insertion plate 34 on the pot cover 3 corresponds to the through hole assembly 15 on the pot body. By adjusting the position of the insertion plate 34, the insertion part 35 at the end of the insertion plate 34 is inserted into the through hole assembly 15 to realize the connection of the pot cover 3 and the pot body. At this time, the sealing member 37 on the pot cover 3 is located in the cooking cavity of the pot body and extends into the pot body. The sealing member 37 and the inner side wall of the pot body are pressed against each other to form a seal for the cooking cavity (the cavity below the sealing member 37) in the pot body. During the cooking process, the pressure in the cooking cavity of the pot body will rise. At this time, the high pressure in the pot body will exert an upward lifting force on the pot cover 3. However, due to the insertion connection of the insertion plate 34 and the through hole assembly 15, the pot cover 3 can be prevented from being separated from the pot body under the action of high pressure, thereby ensuring the safety during the use of the pressure cooker and the sealing effect of the pot body. It should be noted that the matching position of the sealing member 37 and the cooking cavity of the pot body in the embodiment is located on the inner side of the through hole assembly 15. The through hole assembly 15 opened on the pot body can avoid affecting the sealing performance of the pot body, thereby further improving the sealing effect.

[0053] Referring to FIGS. 5, 6, 7 and 8, the pot cover 3 in the embodiment includes an inner cover 32 and an outer cover 31. The positioning block 33 is arranged on the outer cover 31. The inner cover 32 and the outer cover 31 are fixedly connected through a connecting column 39. The outer cover 31 is buckled on the inner cover 32 and covers the insertion plate 34 inside. An open part is formed on the side wall of the outer cover 31 for the movement of the insertion plate 34. The insertion plate 34 in the embodiment is hidden in the outer cover 31. The insertion part 35 at the end of the insertion plate 34 can extend out of or retract into the outer cover 31 along with the movement of the insertion plate 34. When the insertion part 35 extends out of the side wall of the outer cover 31, the insertion plate 34 can be inserted into the through hole assembly 15 on the pot body to realize the connection of the pot cover 3 and the pot body. When the insertion part 35 is retracted, the insertion plate 34 is separated from the through hole assembly 15. At this time, the pot cover 3 can be separated from the pot body. The insertion plate 34 in the embodiment is slidably connected to the inner cover 32.

[0054] The through hole assembly 15 in the embodiment has two forms. One form is that the through hole assembly 15 is a through hole structure, and the insertion part 35 of the insertion plate 34 is also correspondingly provided as one insertion part 35. Another form is that, as shown in FIGS. 2, 3 and 4, the through hole assembly 15 includes a plurality of spaced through holes, and the end of the insertion plate 34 is correspondingly provided with a plurality of insertion parts 35. The number of the insertion parts 35 is equal to the number of the through holes, and each through hole is matched with one insertion part 35. In this way, the pot cover 3 and the pot body can be matched at multiple points, and the stability of the matching of the pot cover 3 and the pot body can be improved.

[0055] Of course, it is conceivable that, in order to ensure that the insertion part 35 can be smoothly inserted into the through hole assembly 15, the size of the hole of the through hole assembly 15 is slightly larger than the size of the insertion part 35, and a circular arc or inclined surface transition structure can be further arranged at the edge of the hole of the through hole assembly 15 and the end of the insertion part 35 to form a guiding effect.

[0056] As shown in FIG. 6, the insertion plate 34 in the embodiment is provided with a guide hole 36, and the connecting column 39 penetrates through the guide hole 36 and the outer wall of the connecting column 39 and the two side walls of the guide hole 36 have mutually abutting portions. As can be seen, the connecting column 39 in the embodiment not only has the effect of connecting the outer cover 31 and the inner cover 32, but also has the effect of guiding the movement of the insertion plate 34, so that the sliding movement of the insertion plate 34 is more stable.

[0057] As shown in FIG. 10, the pot cover 3 in the embodiment is provided with an adjusting member 38. One end of the adjusting member 38 penetrates through and protrudes from the outer cover 31, so as to facilitate the user to control the adjusting member 38. The adjusting member 38 is arranged to drive the synchronous movement of the plurality of insertion plates 34 and drive the insertion part 35 to be inserted into or separated from the through hole assembly 15. The adjusting member 38 includes a main body part 385 and a cover part 384 in actual arrangement. As shown in FIGS. 6 and 9, one of the modes in which the main body part 385 is rotationally connected with the pot cover 3 is that a mounting groove for limiting the main body part 385 is arranged on the inner side wall of the outer cover 31, a limiting plate is arranged on the main body part 385, one end surface of the limiting plate abuts against one end surface of the mounting groove to limit the main body part 385 in the outer cover 31, one end of the main body part 385 penetrates through the outer cover 31 and protrudes from the outer cover 31, and the cover part 384 is buckled on the main body part 385 from the outside of the outer cover 31 to form the adjusting member 38. The cover part 384 and the main body part 385 can be connected by insertion. In this way, the rotation of the cover part 384 can drive the rotation of the main body part 385, and then drive the movement of the insertion plate 34.

[0058] In order to realize the movement of the insertion plate 34, referring to FIGS. 7, 8 and 9, one of the embodiments of the adjusting member 38 in the present embodiment is that the adjusting member 38 is provided with an arc-shaped slot 383 corresponding to the insertion plate 34, one end of the insertion plate 34 is provided with a push rod 341 penetrating through the arc-shaped slot 383, and the rotation of the adjusting member 38 extrudes the outer wall of the push rod 341 through the side wall of the arc-shaped slot 383 to drive the synchronous reciprocating linear movement of the plurality of insertion plates 34. The rotational movement of the adjusting member 38 is converted into the linear movement of the insertion plate 34, which can reduce the occupied volume of the adjusting member 38 and facilitate operation.

[0059] Of course, it is conceivable that the movement structure of the adjusting member 38 driving the insertion plate 34 in the present embodiment has various embodiments, such as: 1. using a cam connecting rod structure, a cam surface is provided on the adjusting member 38, one end of the insertion plate 34 abuts against the cam surface, and a spring is further provided between the insertion plate 34 and the inner cover 32, so that the rotation of the adjusting member 38 can realize the reciprocating linear movement (extension or retraction) of the insertion plate 34 through the cooperation of the cam surface and the spring. 2. using a crank slider mechanism, the adjusting member 38 is provided as a crank, and the insertion plate 34 is provided as a slider, so that the rotation of the adjusting member 38 can realize the reciprocating linear movement of the insertion plate 34. 3. using a gear and rack transmission structure, a gear is provided on the adjusting member 38, and a rack is provided on the insertion plate 34, so that the rotation of the adjusting member 38 can drive the reciprocating linear movement of the insertion plate 34 through the mutual meshing of the gear and the rack. The above three ways are all to realize the reciprocating linear movement of the insertion plate 34 through the rotational movement of the adjusting member 38, and in actual setting, the deformation of the above mechanism can also be used.

[0060] In addition, in actual design, the linear movement of the adjusting member 38 can also be converted into the linear movement of the insertion plate 34, wherein the direction of the linear movement of the adjusting member 38 can be parallel or intersected with the direction of the linear movement of the insertion plate 34, and the movement of the adjusting member 38 can be realized by pinching, lifting or pressing the adjusting member 38, etc. in relation to the operation of the adjusting member 38. In short, only the movement of the adjusting member 38 can drive the synchronous movement of the plurality of insertion plates 34, and the specific arrangement can be selected and set according to actual needs.

[0061] In order to ensure the safety of the pressure cooker during use, referring to FIG. 6, the inner cover 32 of the present embodiment is provided with a through hole, and the inner cover 32 is provided with a stop valve body 4 slidingly connected in the through hole, the stop valve body 4 is arranged to be upwardly moved and stop the rotation of the adjusting member 38 under the pressure of the cooking cavity of the pot body when the insertion part 35 is inserted into the through hole assembly 15. In this way, when the pressure in the cooking cavity is too high during the use of the pressure cooker, the stop valve body 4 moves upwardly and can stop the rotation of the adjusting member 38, at this time, the user cannot make the insertion plate 34 disengage from the through hole assembly 15 by rotating the adjusting member 38, thereby avoiding the safety risk of mistakenly opening the pot cover 3 under the high pressure of the cooking cavity.

[0062] In order to realize that the opening-stopping valve body 4 can stop the rotation of the adjusting member 38, referring to Figures 7 and 8, the adjusting member 38 of the embodiment is provided with a baffle plate 381, one side of the baffle plate 381 is provided with a gap 382, the opening-stopping valve body 4 stops the rotation of the adjusting member 38 by cooperating with the gap 382, at this time, the opening-stopping valve body 4 is in a state of moving to the upper part under the action of high pressure in the cooking cavity, and the opening-stopping valve body 4 can block one side of the opening-stopping valve body 4 to limit the rotation of the adjusting member 38. Of course, in actual setting, a limiting hole can also be opened on the baffle plate, and the adjusting member is stopped or un-stopped by the opening-stopping valve body moving up to extend into the limiting hole and moving down to disengage from the limiting hole.

[0063] Referring to Figures 9 and 10, one end of the opening-stopping valve body 4 of the embodiment is provided with an indicating rod 41, and the outer cover 31 is provided with an indicating hole 42 corresponding to the indicating rod 41, the indicating rod 41 is arranged to move up with the opening-stopping valve body 4, and one end of the indicating rod 41 can extend into the indicating hole 42. It is convenient for the user to observe externally in order to judge the pressure condition in the cooking cavity. In actual setting, the indicating rod 41 can be coaxially arranged with the opening-stopping valve body 4, at this time, only the diameter of the indicating rod 41 needs to be set to be smaller than the diameter of the opening-stopping valve body 4, so that the indicating rod 41 cannot block the baffle plate 381, of course, the indicating rod 41 can be eccentrically arranged with the opening-stopping valve body 4, so that it can avoid the rotating area of the baffle plate 381 and the adjusting member 38.

[0064] Each handle 2 of the embodiment is provided with a positioning hole 21, so that the overall structure of the pot body has more symmetrical beauty, and when the pot cover 3 is placed, the orientation of the pot cover 3 cooperating with the handle 2 does not need to be considered, and the operation is simplified.

[0065] One of the embodiments of the application discloses a pot body, referring to Figures 2 and 3, comprising a pot body 1 and a handle 2 arranged on the pot body 1, the pot body 1 is formed with a cooking cavity, the number of the handle 2 in the embodiment is two, and the two handles 2 are symmetrically arranged on the outer side wall of the pot body 1, and the cooking cavity of the pot body 1 is used for cooking food. It should be noted that the two handles in the embodiment can be arranged as the same structure, of course, they can also be arranged as different structures, such as one is arranged as a short handle and the other is arranged as a long handle.

[0066] The pot body 1 is provided with at least two through hole assemblies 15 on the side wall of the pot body 1, which are used in cooperation with the pot cover 3 to prevent the pot cover 3 from being separated from the pot body under the pressure of the cooking cavity. It can be seen that the through hole assembly 15 in the embodiment is directly arranged on the pot body 1, so that the pot cover 3 can be directly matched with the pot body during use without the need for other components, thereby simplifying the structure of the pot body. It can be seen that the through hole assembly 15 in the embodiment is arranged to cooperate with the pot cover to prevent the pressure cooker from moving upward and separating from the pot body under the high pressure of the cooking cavity during cooking. Its main function is to cope with the high pressure of the cooking cavity of the pot body. In addition, the handle 2 is provided with a positioning portion for cooperating with the pot cover 3. The positioning portion can position the position of the pot cover 3, so that the pot cover 3 can be quickly and accurately placed at a position where the pot cover 3 and the through hole assembly 15 cooperate with each other. In this way, when the pot cover 3 is placed on the pot body, only the relevant components on the pot cover 3 need to be matched with the positioning portion to ensure that the pot cover 3 is placed in place, reducing the need to adjust the position when the pot cover 3 is placed on the pot body, making the operation more convenient.

[0067] The positioning portion can be provided as a positioning hole 21 or a positioning block or other different structures. When the positioning portion on the handle 2 is a positioning hole 21, a positioning block is arranged on the pot cover. When the positioning portion on the handle 2 is a positioning block (not shown in the figure), a positioning hole is arranged on the pot cover. The positioning block is inserted into the positioning hole to realize the cooperation between the handle 2 and the pot cover. The positioning portion in the embodiment is provided as a positioning hole 21.

[0068] In actual arrangement, the through hole assembly 15 can be arranged as two and symmetrically distributed, cooperating with two handles 2 symmetrically distributed (here, symmetry only means that the handles are distributed at symmetrical positions, and does not mean that the two handles must have the same structure). When placing the pot cover 3, the orientation of the pot cover 3 does not need to be considered, further simplifying the operation. Of course, it can be envisaged that the position of the positioning hole 21 on the handle 2 can be arranged at the upper end face, side face or other implementable positions of the handle 2, as long as it can cooperate with the pot cover 3.

[0069] The inner wall of the pot body 1 in the embodiment forms a sealing area for cooperating with the pot cover 3, and the through hole assembly 15 is arranged between the end of the pot body opening and the sealing area. In use, the pot cover 3 is placed on the pot body, and the pot cover 3 cooperates with the pot body at the sealing area of the pot body to form a seal. As can be seen from the figure, the sealing area is arranged inside the through hole assembly 15, which can avoid the influence of the through hole assembly 15 opened on the pot body on the sealing performance of the pot body, thereby improving the sealing effect.

[0070] It should be noted that the number of through hole assemblies 15 in the embodiment can also be more than two, such as three, four or more. The plurality of through hole assemblies 15 are evenly distributed in the circumference of the pot body 1.

[0071] Further, the handle 2 in the embodiment is arranged at a position corresponding to the through-hole assembly 15. Here, the corresponding position means that the handle 2 and the through-hole assembly 15 are arranged at the same orientation on the pot body 1, so that the handle 2 can shield the through-hole assembly 15, and the user cannot see the through-hole assembly 15 from the outside, improving the appearance effect of the pressure cooker; in addition, the positions of the handle 2 and the through-hole assembly 15 correspond to each other, which is convenient for the user to observe the cooperation of the positioning hole 21 and the pot cover 3 and the cooperation of the through-hole assembly 15 and the pot cover 3. Of course, the orientations of the handle 2 and the through-hole assembly 15 can also be arranged at different orientations, such as two handles 2 and two through-hole assemblies 15 being arranged in a cross shape. Each handle 2 can be provided with a positioning hole 21, so that the overall structure of the pot body has more symmetrical beauty, and when the pot cover 3 is placed, the orientation of the cooperation of the pot cover 3 and the handle 2 does not need to be considered, simplifying the operation.

[0072] The connection structure of the handle 2 and the pot body 1 in the embodiment has the following modes: first, referring to FIG. 2, the handle 2 and the pot body 1 are an integral structure, and in production, the pot body 1 and the handle 2 are integrally formed, so that the pot body has better overallity and strength. Second, referring to FIG. 3, the handle 2 and the pot body 1 are detachably connected, and in the connection structure, a connecting hole 16 can be formed on the side wall of the pot body 1, and the handle 2 is connected with the pot body 1 through a screw passing through the connecting hole 16 from the inside of the pot body 1. In this way, the connecting screw, gasket and other connecting members of the handle 2 and the pot body 1 cannot be seen from the outside, improving the appearance effect of the pot body.

[0073] Referring to FIG. 4, in order to ensure the connection effect when the pot cover 3 and the pot body are cooperated, the sum (2*θ) of the central angles of the plurality of through-hole assemblies 15 distributed in the circumferential direction of the pot body 1 in the embodiment is not less than 72°, that is, the distribution length (arc length) of the through-hole assembly 15 in the circumferential direction of the pot body 1 is not less than 1 / 5 of the circumferential length of the pot body 1 where the through-hole assembly 15 is located, so that the length of the cooperation section of the pot cover 3 and the pot body 1 is limited, improving the stability of the cooperation of the pot cover 3 and the pot body 1. It should be noted that the limitation of the central angle in the embodiment is the sum of the central angles of the plurality of through-hole assemblies 15, and when the through-hole assembly 15 is provided with n (n>2) through-hole assemblies, the central angle θ of each through-hole assembly 15 is not less than 72 / n°.

[0074] In addition, it should be noted that the through-hole assembly 15 in the embodiment has the following two modes when actually arranged. First, the through-hole assembly 15 is arranged with an arc length longer hole (not shown in the figure) distributed in the circumferential direction, so that the hole operation of the pot body 1 is more convenient during production, and the production efficiency is improved. Second, referring to FIG. 4, each through-hole assembly 15 includes a plurality of spaced through-holes and a spacing between adjacent through-holes. At this time, the through-hole assembly 15 and the pot cover 3 can be multi-point matched to further improve the stability of the pot body and the pot cover 3. Of course, it can also reduce the amount of removal of the pot body 1, and improve the overall strength of the pot body 1.

[0075] The pot body 1 in the embodiment includes a first straight cylinder 11, a tapered cylinder 12, a second straight cylinder 13, and a bottom plate 14 connected in sequence. One end of the first straight cylinder 11 forms an open end of the pot cooking cavity. The through-hole assembly 15 is arranged on the side wall of the first straight cylinder 11 and is arranged on the straight cylinder wall. This facilitates production and manufacturing. The inner side wall of the tapered cylinder 12 forms a sealing area. As can be seen from the figure, the upper end opening of the tapered cylinder 12 in the embodiment is larger than the lower end opening. In this way, when the pot cover 3 is buckled on the pot body, the arrangement of the tapered cylinder 12 can improve the sealing effect between the pot cover 3 and the pot body. In actual arrangement, in order to ensure the appearance of the pot body and avoid scratching the user, the edge position and the corner position of the pot body can be arranged with a smooth transition.

[0076] The embodiment is further provided with a flange extending outwardly at the open end of the pot body 1. The flange is provided with a guide groove. The arrangement of the guide groove facilitates the buckling of the pot cover 3 on the pot body.
