Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0040] Example 1

[0041] This embodiment provides a cover opening structure, such as Figure 1-13 As shown, the opening cover structure is used to connect the cover body 1 and the main body. The opening cover structure includes a bracket 3, a support ring 4 and a connecting component. The bracket 3 is connected to the cover body 1, the support ring 4 is fixed on the main body, one end of the connecting component is fixed in the support ring 4, and the other end of the connecting component is inserted into the bracket 3; there is a track 31 in the bracket 3, and the other end of the connecting component can move along the track 31, and the track 31 has a first position for realizing the rotation and opening of the cover body 1 relative to the main body, and a second position for separating the cover body 1 from the main body.

[0042] In order to realize the connection between the cover body 1 and the main body, the opening cover structure provided in this embodiment adds a bracket 3, a support ring 4 and a connecting component. The bracket 3 is hingedly connected to the cover body 1, and the support ring 4 is fixed on the main body. The connecting component simply controls the connection relationship between the cover body and the main body by controlling the connection relationship between the bracket 3 and the support ring 4.

[0043] Specifically, when the cooking method is to make soup, etc., which only requires the lid 1 to be able to open and close to a certain angle relative to the main body, and there is no need to take the lid 1 off, press the lid 1, and the other end of the connecting component moves in the track 31. When it moves to the first position, the lid 1 is rotated and opened relative to the main body; when the cooking method is hot pot, etc., which requires the lid 1 to be separated from the main body, continue to press the lid 1, and the other end of the connecting component continues to move in the track 31. When it moves to the second position, the lid 1 is separated from the main body; that is, the opening structure provided by the present invention can not only support the opening and closing of the lid 1 and have a certain angle with the main body, but also allow the lid 1 to be completely taken off. Compared with the traditional electric rice cooker with a single opening method, which cannot meet multiple cooking methods at the same time, this embodiment is obviously convenient and fast, and is suitable for a variety of different cooking methods.

[0044] In the cover opening structure provided in this embodiment, the track 31 has a first position and a second position, specifically: when the other end of the connecting component moves in the track 31, after it moves to the first position, the connecting component is locked with the bracket 3. Since the bracket 3 and the cover body 1 are connected by a hinge, the cover body 1 can be rotated to open and close relative to the bracket 3 at this time. In this case, the track 31 has a first position to realize the rotation and opening of the cover body 1 relative to the main body; under the action of external force, the other end of the connecting component breaks through the first position and continues to move. When it moves to the second position, the connecting component slides along the track 31 until it disengages. In this case, it is the second position where the cover body 1 is separated from the main body.

[0045] It can be seen from the above description that the second position does not refer to the position where the cover 1 is separated from the main body, but refers to the fact that the cover 1 can be separated from the main body due to the existence of the second position.

[0046] In a specific embodiment, Figure 2 、 Figure 3 、 Figure 8 as well as Figure 9 As shown, the connecting assembly 2 includes a guide rod 21, the tail of the guide rod 21 is connected to the support ring 4, and a guide ball 22 is provided on one side of the end of the guide rod 21, and the guide ball 22 matches the track 31; the connecting assembly also includes a spring 23, the spring 23 is provided in the support ring 4, and the bracket 3 is in contact with the spring 23.

[0047] Specifically, the guide ball 22 matches the track 31, so that the guide ball 22 can drive the entire guide rod 21 to move along the track 31. The guide rod 21 is a plate-like structure, and the top of one side is connected to the guide ball 22 through a connecting rod. In this specific implementation process, not only the guide ball 22 needs to match the track 31, but the shape of the guide rod 21 also needs to match the track 31. In addition, a hole is provided somewhere in the support ring 4, and a spring 23 is provided inside the hole, and the spring 23 is able to contact the lower end of the bracket 3.

[0048] When the cover 1 is to be removed, the cover 1 is pressed, and the spring 23 is compressed by the cover 1 through the bracket 3, and the bracket 3 moves downward, and the guide ball 22 slides in the track 31. When it feels resistance, it stops pressing. At this time, the spring 23 needs to return to its original state, and the guide rod 21 slides along the track 31 until it is out of the track, and the cover 1 can be removed. When the cover 1 needs to be assembled on the body, the bracket 3 is inserted into the support ring 4, and the guide rod 21 enters the track 31 again, and the cover 1 is pressed. The guide ball 22 on the guide rod 21 slides along the track 31, and the spring 23 is compressed by the pressure until the cover 1 stops pressing after it feels resistance. After that, the spring 23 needs to return to its original state, and therefore pushes the cover 1 upward, and the guide ball 22 passes through the first position to lock the cover 1, and the cover 1 can be rotated to open and close relative to the bracket 3.

[0049] This embodiment cleverly utilizes the restoring force of the spring 23 , and of course also needs to be combined with the shape of the track 31 , so that the cover 1 can be transformed into different states under the action of the spring 23 and then the guide rod 21 .

[0050] In a specific embodiment, Figure 8 and Figure 9 As shown, the support ring 4 is provided with a connecting portion 41 , which is provided with a mounting groove 42 , in which the spring 23 is located; the connecting portion 41 also has a fixing position 43 , in which the tail of the guide rod 21 is arranged.

[0051] The shape of the support ring 4 matches the shape of the main body and is mainly used to cooperate with the cover body 1 and the connecting assembly; in order to achieve connection with the cover body 1, a connecting portion 41 is provided on the support ring 4, and the connecting portion 41 has a mounting groove 42. The mounting groove 42 has a certain depth and can cooperate with the bottom of the bracket 3 while placing the spring; a fixing position 43 for fixing the guide rod 21 is provided on the connecting portion 41.

[0052] More specifically, the tail of the guide rod 21 gradually shrinks inward and has a through hole. The fixing position 43 is a groove structure with two fixing plates. Each fixing plate is provided with a short cylinder. When installing the guide rod 21, the short cylinder is inserted into the through hole to achieve installation.

[0053] In a specific embodiment, Figure 11 and Figure 12 As shown, the bracket 3 includes a bracket body 32 , a first fixing member 33 extending downward from the bottom of the bracket body 32 , the first fixing member 33 contacts the spring 23 , a second fixing member 34 also extending downward from the bottom of the bracket body 32 , and the track 31 is opened on the second fixing member 34 .

[0054] Furthermore, first fixing members 33 extend downward from both sides of the bottom of the bracket body 32 , two springs 23 are provided, and two mounting grooves 42 are provided. The first fixing members 33 , the mounting grooves 42 and the springs 23 correspond to each other one by one.

[0055] The bracket body 32 is a plate-like structure. On the lower side of the plate-like structure, there are two first fixing members 33 and a second fixing member 34, wherein the second fixing member 34 is located between the two first fixing members 33, and the first fixing member 33 and the second fixing member 34 are also plate-like structures; the first fixing member 33 is mainly used to contact the spring 23, so the shape of the first fixing member 33 matches the installation groove 42. During assembly, the spring 23 is placed in the installation groove 42, and then the first fixing member 33 is inserted into the installation groove 42; the second fixing member 34 is mainly used to connect with the guide rod 21 through the track 31; the track 31 is a groove opened on the surface of the second fixing member 34, and the structure of the groove is similar to the heart of a peach.

[0056] In a specific embodiment, Figure 12 As shown, the track 31 includes a first track segment 311, a second track segment 312, a third track segment 313 and a fourth track segment 314 that are vertically arranged; the second track segment 312 extends from the top of the first track segment 311 to one side, and the third track segment 313 extends from the top of the first track segment 311 to the other side, and the second track segment 312 and the third track segment 313 are also connected by the fourth track segment 314; the first position is located on the second track segment 312, and the second position is located on the third track segment 313.

[0057] In other words, the exit of the first track segment 311 is divided into two paths: one path passes through the second track segment 312 and connects to one end of the fourth track segment 314, and the other path passes through the third track segment 313 and connects to the other end of the fourth track segment 314. The motion trajectory of the guide rod 21 is: first track segment 311, second track segment 312, fourth track segment 314, third track segment 313, and then returns to the first track segment 311. In a movement cycle (the movement cycle refers to the first track segment 311, the second track segment 312, the fourth track segment 314, the third track segment 313, and then returns to the first track segment 311), the first track segment 311 and the second track segment 312 are paths in which the cover body 1 and the main body are connected, that is, in this path, the cover body 1 can be rotated and opened and closed relative to the main body, but the two cannot be separated; the fourth track segment 314 is a transition segment between the two states of the cover body 1, and the subsequent third track segment 313 and the first track segment 311 are paths where the cover body 1 and the main body are about to be separated, that is, after the path, the cover body 1 can be directly removed relative to the main body.

[0058] In a specific embodiment, the first track segment 311 is vertically arranged, the second track segment 312 and the third track segment 313 each include a vertical segment and a horizontal segment, and the fourth track segment 314 is horizontally arranged; one end of the fourth track segment 314 is connected to the horizontal segment of the second track segment 312, and the other end is connected to the horizontal segment of the third track segment 313, and the fourth track segment 314 is lower than the horizontal segment of the second track segment 312 and the horizontal segment of the third track segment 313.

[0059] Of course, the above-mentioned horizontal segment is not an absolutely horizontal segment, and it has a certain curvature; the vertical segment is not an absolutely vertical segment, and it has a certain slope; this embodiment mainly emphasizes that the fourth track segment 314 is lower than the horizontal segment of the second track segment 312 and the horizontal segment of the third track segment 313, and is used when the guide ball 22 slides in the track 31 and feels resistance and releases the pressure, so that the guide ball 22 can move to the lower fourth track segment 314 and then be fixed in this position.

[0060] In a specific embodiment, the first position is located in the horizontal section of the second track segment 312, and the first position is higher than the rest of the horizontal section of the second track segment 312; the second position is located in the horizontal section of the third track segment 313, and the second position is higher than the rest of the horizontal section of the third track segment 313.

[0061] It should be noted that the first position is not the position where the cover 1 is rotated open relative to the main body, but after passing the first position, the cover 1 can be rotated open relative to the main body. Specifically: the first position is higher than the rest of the positions of the horizontal section of the second track segment 312, that is, when the guide ball 22 slides in the track 31, this position is the position where the guide ball feels resistance. After stopping pressing at this position, the spring 23 needs to recover. At this time, the guide ball 22 will move along the arc toward the fourth track segment 314, and then be locked at the fourth track segment 314.

[0062] Similarly, the second position is not the position where the cover 1 is detached from the main body, but after passing the second position, the cover 1 can be removed from the main body. Specifically: the second position is higher than the rest of the horizontal section of the third track segment 313. After pressing the cover 1 again, the guide ball 22 slides to the second position and feels resistance. After stopping pressing at this position, the guide ball 22 will move along the third track segment 313 and the first track segment 311 until the cover 1 is detached from the main body.

[0063] In a specific embodiment, at one end where the second track segment 312 is connected to the first track segment 311 and at one end where the third track segment 313 is connected to the first track segment 311, the area of ​​the exit end of the first track segment 311 covered by the second track segment 312 is larger than the area of ​​the exit end of the first track segment 311 covered by the third track segment 313, so that the other end of the connecting assembly can first enter the second track segment 312.

[0064] That is to say, the exit of the first track segment 311 is divided into two paths, the first path is connected to one end of the fourth track segment 314 through the second track segment 312, and the second path is connected to the other end of the fourth track segment 314 through the third track segment 313; among them, the second path covers a larger area of ​​the exit end of the first track segment 311, the purpose is to make the moving trajectory of the guide ball 22: the first track segment 311, the second track segment 312, the fourth track segment 314, the third track segment 313, and then return to the first track segment 311; instead of the first track segment 311, the first track segment 311, the fourth track segment 314, the second track segment 312, and then return to the first track segment 311.

[0065] In a specific embodiment, at one end where the second track segment 312 is connected to the fourth track segment 314 and at one end where the third track segment 313 is connected to the fourth track segment 314, the lowest point of the fourth track segment 314 is close to the third track segment 313, so that the other end of the connecting component can enter the third track segment 313 after passing through the fourth track segment 314, instead of returning to the second track segment 312 after passing through the fourth track segment 314.

[0066] The assembly process of the cover opening structure provided in this embodiment is as follows:

[0067] The bracket 3 is connected to the cover 1 via a hinge axis; the spring 23 is installed in the mounting groove 42 of the support ring 4; the through hole at the bottom of the guide rod 21 can be installed in the support ring 4 and connected to the two short cylinders on the fixed plate, which can achieve a small rotation of the guide ball 22 at the top of the guide rod 21, causing it to slide in the track 31; the cover 1 with the bracket 3 is inserted into the groove of the support ring 4. Because the bracket 3 has the track 31, when the cover 1 is pressed down, the guide rod 21 enters the track 31 and reaches the predetermined position. The track 31 prevents the guide rod 21 from falling out, and the cover 1 is locked. Then, press again, and the guide rod 21 slides along the track 31 and falls out, unlocking the cover 1 and allowing it to be removed.

[0068] The working process of the cover opening structure provided in this embodiment is as follows:

[0069] Assume that the cover 1 and the body are currently connected. Figure 4 、 Figure 5 as well as Figure 10 As shown, the guide ball 22 is located at the fourth track segment 314; if you want to remove the cover 1, press the cover 1 toward the main body, as shown in FIG. Figure 2 and Figure 3As shown, at this time, the guide rod 21 installed on the support ring 4 slides along the track 31. When it slides to the highest point of the third track segment 313 (i.e., the second position), it feels resistance. At this time, the pressure is released and the spring 23 needs to recover. Then the guide rod 21 slides along the third track segment 313 and the first track segment 311 until it falls out. At this time, the cover body 1 can be removed.

[0070] When the cover 1 needs to be installed, pick up the cover 1 and insert the second fixing piece 34 of the bracket 3 into the support ring 4. The guide rod 21 then enters the track 31. When the cover 1 is pressed downward, the guide ball 22 on the guide rod 21 slides from the first track segment 311 to the second track segment 312. The spring 23 in the support ring 4 is also compressed and presses the cover downward. When the guide ball 22 reaches the highest position (i.e., the first position) of the second track segment 312, resistance is felt. At this time, the pressure is stopped and the spring 23 needs to recover. Therefore, the cover 1 is pushed upward and the guide ball 22 of the guide rod 21 slides to the predetermined position in the middle of the track 31 (i.e., the fourth track segment 314). Figure 4 、 Figure 5 as well as Figure 11 As shown, the cover body 1 is locked.

[0071] Example 2
