Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1 to 3 and 9 to 12, the detachable hinge connection structure of the present embodiment includes a mounting base 10 and a connection portion 30. Wherein, the mounting base 10 is provided with a first clamping matching part 20. The connecting portion 30 is detachably connected to the mounting seat 10, and a positioning structure 40 is disposed between the connecting portion 30 and the mounting seat 10. Further, the connecting portion 30 is adapted to be rotatably connected with the opening and closing structure 50 through the rotating shaft 60, the opening and closing structure 50 is provided with a second snap-fit portion 70, and the opening and closing structure 50 has a closed position and an open position relative to the mounting base 10. Specifically, when the opening and closing structure 50 is in the open position, the second snap-fit portion 70 is misaligned with the first snap-fit portion 20, so that the connecting portion 30 can be detached from the mounting base 10; when the opening and closing structure 50 is in the closed position, the first clamping matching part 20 is in clamping matching with the second clamping matching part 70 so as to fix the connecting part 30 on the installation seat 10.

With the technical solution of this embodiment, when the opening and closing structure 50 is in the closed position, the second clamping matching portion 70 on the opening and closing structure 50 is in clamping matching with the first clamping matching portion 20 on the mounting seat 10, so that the connecting portion 30 is fixed on the mounting seat 10. When the opening and closing structure 50 moves to the opening position, the second clamping matching part 70 on the opening and closing structure 50 moves synchronously, and the second clamping matching part 70 and the first clamping matching part 20 are staggered, so that the connecting part 30 can be detached from the mounting seat 10, and the opening and closing structure 50 is detached. Above-mentioned structure makes when the user need pull down the structure 50 that opens and shuts, only need with open and shut structure 50 remove to open the position can, need not to add other unblock buttons again, only need the one hand can operate simultaneously, simplified the dismantlement operation of the structure that opens and shuts greatly. Therefore, the technical scheme of the embodiment overcomes the defect that the disassembly operation of the cover of the electric cooker in the prior art is more complicated.

It should be noted that the mounting base 10 is disposed on a relatively fixed structure of an electric appliance or other mechanical structure, and the "opening and closing structure 50" refers to a structure that can be opened or closed relative to the fixed structure. For example, the opening and closing structure 50 may be a lid that can be opened and closed, a cabinet door that can be opened and closed, a door panel, a cover plate, a flap, a cover, and the like. It will be appreciated by those skilled in the art that a structure that is openable and closable with respect to a fixed structure and is mounted with a hinge may be used as the "opening and closing structure 50" described above.

For convenience of explanation, when the detachable hinge connection structure in the present embodiment is described in detail below, the detachable hinge connection structure is used to connect the pot body and the pot cover of the electric rice cooker (i.e. the pot cover is the opening and closing structure 50). However, it will be understood by those skilled in the art that any structure that can be opened and closed by using a hinge can be the above-mentioned detachable hinge connection structure, and the following examples cannot be understood that the detachable hinge connection structure of the present embodiment can only be applied to an electric rice cooker.

As shown in fig. 5 and 8, in the solution of the present embodiment, the first snap-fit portion 20 is a sliding slot, and the second snap-fit portion 70 is a sliding block. When the opening and closing structure 50 is at the opening position, the sliding block is located outside the sliding groove, and when the opening and closing structure 50 moves from the opening position to the closing position, the sliding block moves into the sliding groove. Specifically, the opening and closing structure 50 can rotate about the rotation shaft 60 when the opening and closing structure 50 is opened or closed. Since the connection portion 30 is connected to the mounting seat 10, the opening and closing structure 50 is also rotated with respect to the mounting seat 10. The slider on the opening and closing structure 50 thus moves relative to the chute as the opening and closing structure 50 moves between the open and closed positions. As can be seen from fig. 9 and 10, when the opening and closing structure 50 is in the open position, the sliding block is separated from the sliding groove, and the connecting portion 30 can be detached from the mounting base 10 from the bottom. As can be seen from fig. 11 and 12, when the opening and closing structure 50 is in the closed position, the sliding block is embedded into the sliding groove and is limited by the upper side wall of the sliding groove, and the connecting portion 30 is fixed on the mounting seat. That is, when the opening and closing mechanism 50 is in the closed position, the connecting portion 30 is fixed on the mounting seat 10 and cannot be detached, and when the opening and closing mechanism 50 is in the open position, the connecting portion 30 can be detached from the mounting seat 10.

Further, it can be understood by those skilled in the art that the specific form of the first and second snap-

fit portions

20 and 70 can be reversed, that is, the first snap-fit portion 20 is a sliding block, and the second snap-fit portion 70 is a sliding slot. It is also possible that the opening and closing structure 50 drives the sliding slot to move relative to the sliding block when the opening and closing structure 50 moves between the open position and the closed position.

Of course, it will be understood by those skilled in the art that the first and second snap-

fit portions

20, 70 may also take other forms, for example, the first and second snap-

fit portions

20, 70 are each a snap block.

Meanwhile, as can be seen from fig. 12, by adjusting the sizes of the sliding groove and the sliding block, when the sliding block is inserted into the sliding groove, a preset gap (i.e., d in fig. 12) between the sliding block and the upper side wall of the sliding groove is kept within a reasonable size interval. Preferably, the size of the preset gap is smaller than 1 millimeter, the size ensures that the sliding block cannot be clamped in the sliding groove, and the phenomenon of air leakage caused by that steam pushes the cooker cover when cooking is caused due to the fact that the assembly gap between the cooker body and the cooker cover is too large is prevented when the electric cooker works. Preferably, the gap d can be adjusted according to requirements, so that after the cover of the electric rice cooker is closed, the assembly gap between the cooker body and the cooker cover is less than or equal to 1.2mm, the uniformity of the gap is less than or equal to 0.6mm, and the phenomena that the appearance is influenced by uneven gaps and the gap is too large and air leakage is bad are avoided.

As shown in fig. 10 and 12, in the technical solution of this embodiment, the sliding groove is an arc-shaped groove, the sliding block is an arc-shaped block, and the radian of the arc-shaped sliding groove is matched with the radian of the arc-shaped block. Specifically, since the movement locus of a certain point on the opening and closing structure 50 is an arc when the opening and closing structure 50 moves between the open position and the closed position, the slider is designed as an arc-shaped block, and the sliding chute is in an arc-shaped locus along the extending direction. The above structure enables the slider to move smoothly relative to the chute without jamming when the opening and closing structure 50 moves between the open position and the closed position. Meanwhile, the structure arrangement can also ensure that the gap between the sliding block and the sliding groove is as small as possible.

Of course, the slider may have other shapes with an arc-shaped surface, or the slider may have other shapes with a plane surface as long as the slider can slide in the arc-shaped sliding groove.

As shown in fig. 4, 7 and 8, in the solution of the present embodiment, the positioning structure 40 includes an insertion block 41 and an insertion slot 42, the insertion block 41 is disposed at the bottom of the connection portion 30, the insertion slot 42 is disposed on the mounting base 10, and when the connection portion 30 is connected to the mounting base 10, the insertion block 41 is inserted into the insertion slot 42. Specifically, when the lid is mounted, the insertion block 41 is first inserted into the insertion slot 42, and the lid is in the open position. After the position of the pot cover is fixed through the slot 42 and the insertion block 41, the pot cover is moved to a closed position, and the sliding block is embedded into the sliding groove, so that the pot cover is installed. Therefore, the above-mentioned insert block 41 and slot 42 have two functions, one is to perform the function of positioning the connecting part 30 in advance when the pot cover is installed; the other function is that when the pot cover is in the open position, if the user does not need to detach the pot cover, the pot cover can be kept in the state of being installed on the pot body under the positioning action of the insertion block 41 and the insertion slot 42, and the pot cover is prevented from falling off the pot body.

Of course, it will be understood by those skilled in the art that the positions of the insert block 41 and the slot 42 can be reversed, that is, the insert block 41 is disposed on the mounting seat 10, and the slot 42 is disposed at the bottom of the connecting portion 30, which is a possible embodiment.

As shown in fig. 7, in the solution of the present embodiment, the opposite side walls of the slot 42 are provided with positioning ribs 421. Specifically, the positioning ribs 421 are disposed on two side walls in the left-right direction of the insertion groove 42, and the positioning ribs 421 can accurately position the pot cover in the left-right direction with respect to the pot body, so that the assembly accuracy is ensured, and the loosening of the pot cover is prevented.

Of course, in some embodiments, which are not shown, the positioning ribs 421 may be provided on two side walls of the slot 42 in the front-rear direction, or the positioning ribs 421 may be provided on the side walls of the slot 42 in the front-rear direction, the left-right direction, and the like.

Specifically, two support blocks 80 are respectively located at the left and right sides of the slot 42, and the support blocks 80 extend in a direction away from the mount base 10. Each supporting block 80 is provided with the sliding groove, and the sliding groove penetrates through the side wall of the supporting block 80 facing forward and forms an opening, so that when the pot cover moves to the closed position, the sliding block can enter the sliding groove from the opening. The supporting block 80 has a technical effect of facilitating the arrangement of the sliding groove.

As shown in fig. 4, in the solution of the present embodiment, the connection portion 30 is provided with the receiving recess 31 at both sides in the axial direction of the rotating shaft 60, the receiving recess 31 penetrates through the bottom surface of the connection portion 30 and the side surface of the connection portion 30 in the axial direction of the rotating shaft 60, and when the connection portion 30 is connected to the mounting seat 10, the supporting block 80 is located in the receiving recess 31. Specifically, the accommodation recess 31 forms the left and right ends of the connecting portion into a notched structure having two openings directed downward and to the side portions. As can be seen from fig. 4 and 8, when the connecting portion 30 is mounted, the accommodating recess 31 is disposed outside the supporting block 80 from top to bottom, so that the side walls of the accommodating recess 31 in the front-back direction can limit the supporting block 80. The receiving recess 31 can precisely position the lid with respect to the front and rear direction of the pot body, thereby ensuring assembly accuracy and preventing the lid from being loosened.

Further, the number of the receiving recesses 31 is two, and when the connecting portion 30 is connected to the mounting base 10, the two receiving recesses 31 are correspondingly engaged with the two supporting blocks 80.
