Description

Technical Field

[0001] This utility model relates to the field of connection structure technology, and more specifically, to a mortise and tenon connection structure and an automatic cooking machine. Background Technology

[0002] Automatic cooking machines are a new type of cooking equipment that can replace manual labor in cooking dishes. They can perform functions such as stir-frying, pan-frying, braising, deep-frying, quick-frying, stewing, and steaming, saving manpower. There are many types of automatic cooking machines on the market, including stirring type, drum type, and tossing type. Among them, the simple stirring type can be made in a smaller size, making it more suitable for home use.

[0003] Currently, most simple stirring-type stir-fry machines use an integrated structure where the stirring arm and lid are combined. The lid has an external drive motor, while the stirring arm is connected inside. The lid is placed on the pot, and stirring begins. Once stirring stops, the lid is lifted by the tilting arm. This design allows for relatively simple and effective automatic stirring of food. However, because the lid and stirring arm are fixed together, disassembling them is difficult and requires specialized tools. Cleaning the inside of the stirring arm and lid is also challenging, especially when changing the stirring arm for different stir-frying tasks. Utility Model Content

[0016] In some preferred embodiments, the unlocking component includes a push-pull rod and a third elastic connector. The tenon body has a mounting hole along a second direction, and the push-pull rod is assembled into the mounting hole through the third elastic connector. The position of the push-pull rod corresponds to the position of the mortise.

[0017] In some preferred embodiments, the unlocking assembly further includes a limiting member fixed in the mounting hole and having a hole through which the push-pull rod passes. The push-pull rod has a limiting portion, and the third elastic connector is a third spring, one end of which abuts against the limiting member, and the other end of which abuts against the limiting portion of the push-pull rod.

[0018] In some preferred embodiments, the mortise body has a tenon guide groove along the second direction, and the tenon guide groove is connected to the first mortise hole.

[0019] This utility model also provides an automatic cooking machine, including a pot body, a pot lid, a stirring robot, and the above-mentioned mortise and tenon connection structure.

[0039] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0040] Example 1

[0041] refer to Figures 1 to 10 This embodiment discloses a mortise and tenon connection structure, including a tenon assembly 1, a mortise assembly 2, and an unlocking assembly 3. The tenon assembly 1 and the mortise assembly 2 can be connected to each other to form a stable connection structure, and the connection between the tenon assembly 1 and the mortise assembly 2 can be released by the unlocking assembly 3. Specifically, refer to... Figure 3 and Figure 4 The tenon assembly 1 includes a tenon body 101, a first tenon 102, and a second tenon 103, wherein the first tenon 102 is elastically connected to the tenon body 101, and the second tenon 103 is fixedly connected to the tenon body 101. (Reference) Figure 3 , Figure 5 and Figure 6 The mortise assembly 2 includes a mortise body 201 and a mortise piece 204. The mortise piece 204 is elastically connected to the mortise body 201. The mortise body 201 has a first mortise 202, and the mortise piece 204 has a second mortise 203. A first tenon 102 is inserted into the first mortise 202, and a second tenon 103 is inserted into the second mortise 203. (Reference) Figure 3 and Figure 7 The unlocking component 3 is movably connected to the tenon body 101 to disengage the second mortise 203 from the second tenon 103.

[0042] In this embodiment, the tenon assembly 1 and the mortise assembly 2 are fixedly connected by inserting the first tenon 102 into the first mortise 202 and the second tenon 103 into the second mortise 203. The first tenon 102 is elastically connected to the tenon body 101, allowing it to elastically extend and retract during assembly, thus preventing interference between the first tenon 102 and the mortise body 201. The mortise 204 is elastically connected to the mortise body 201. The unlocking component 3 can push the mortise 204 to elastically move within the mortise body 201, thereby disengaging the mortise 204 from the second tenon 103. Simultaneously, the first tenon 102 can also disengage from the first mortise 202, thus enabling unlocking between the tenon assembly 1 and the mortise assembly 2.

[0043] refer to Figure 3 In this embodiment, the insertion direction of the first tenon 102 and the first mortise 202 is defined as the first direction, that is... Figure 3 In the X direction, the insertion direction of the second tenon 103 and the second mortise 203 is the second direction, that is... Figure 3 In the Y-direction, the first direction and the second direction are arranged intersectingly. Preferably, in this embodiment, the first direction and the second direction are perpendicular to each other, making the connection between the tenon assembly 1 and the mortise assembly 2 more stable. Of course, in other embodiments, the first direction and the second direction can also be at other angles.

[0044] refer to Figure 3 and Figure 4 In this embodiment, the tenon body 101 has a tenon guide groove 105 along the first direction, and also includes a first elastic connector 104. The first tenon 102 is installed in the tenon guide groove 105 through the first elastic connector 104. In this embodiment, the first elastic connector 104 is a first spring, one end of which is connected to the first tenon 102, and the other end is connected to the tenon guide groove 105. During the connection process between the tenon assembly 1 and the mortise assembly 2, when the connection is not completed, the mortise body 201 can push the first tenon 102 back into the tenon guide groove 105 to avoid interference between the first tenon 102 and the mortise body 201; when the connection is completed, the tenon guide groove 105 is aligned with the first mortise 202 in the first direction, i.e., the X direction, so the first tenon 102 naturally enters the first mortise 202 under the action of the spring, realizing the insertion of the first tenon 102 and the first mortise 202. To facilitate the assembly of the first elastic connector 104 and the first tenon 102 in the tenon guide groove 105, an openable end cap can be provided on one side of the tenon guide groove 105, for example, an end cap is provided on the upper side of the tenon guide groove 105.

[0045] In this preferred embodiment, L-shaped mounting plates are connected to both ends of the first spring, and the L-shaped mounting plates and the spring can be welded together. The L-shaped mounting plates facilitate the connection between the first spring and the tenon guide groove 105 and the first tenon 102. The L-shaped mounting plates can be welded or threaded to the tenon guide groove 105 and the first tenon 102.

[0046] refer to Figure 3 and Figure 6 The mortise body 201 has a tenon guide groove 207 along the second direction, and the tenon guide groove 207 connects to the first mortise hole 202. The second direction is... Figure 3 In the Y direction, the tenon guide groove 207 guides the first tenon 102 into the first mortise 202. During the connection of the tenon assembly 1 and the mortise assembly 2, when the connection is not yet complete, the first tenon 102 is in the tenon guide groove 207 and slides in the tenon guide groove 207 along the Y direction. When the connection is complete, the first tenon 102 falls from the end of the tenon guide groove 207 into the first mortise 202 under the action of the first elastic element to achieve the connection. It can be understood that the depth of the first mortise 202 in the X direction is greater than the depth of the tenon guide groove 207 in the X direction. Therefore, the connection is completed after the first tenon 102 falls into the first mortise 202, and the first tenon 102 will not move in the opposite direction along the tenon guide groove 207 and disengage from the first mortise 202. Preferably, the first tenon 102 has an inclined surface facing the moving direction of the mortise body 201, and the contact between the mortise body 201 and the inclined surface of the first tenon 102 makes it easier to push the first tenon 102.

[0047] refer to Figures 1 to 3 ,as well as Figure 5 and Figure 6 The mortise assembly 2 also includes a second elastic connector 205. A mortise guide groove 206 is formed in the mortise body 201 along a second direction. The mortise member 204 is installed in the mortise guide groove 206 via the second elastic connector 205. In this embodiment, the second elastic connector 205 is a second spring, one end of which is connected to the mortise member 204, and the other end of which is connected to the mortise guide groove 206. The mortise body 201 has the mortise guide groove 206 formed along the second direction, that is, the mortise body 201 along... Figure 3A guide groove 206 is provided in the Y direction, allowing the mortise component 204 to move elastically along the Y direction. A second mortise 203 is provided inside the mortise component 204 along the Y direction. The second tenon 103 extends from the tenon body 101 along the Y direction. Therefore, after the tenon assembly 1 and the mortise assembly 2 are connected, the second mortise 203 of the mortise component 204 can fit onto the second tenon 103 of the tenon body 101. Since the mortise component 204 is connected to the guide groove 206 using a second elastic element, it can be pushed away from the second tenon 103 by the unlocking component 3, thus unlocking the second tenon 103 from the second mortise 203. After the second tenon 103 is unlocked from the second mortise 203, applying force in the X direction easily separates the first tenon 102 from the first mortise 202, thereby unlocking the tenon assembly 1 from the mortise assembly 2.

[0048] In this preferred embodiment, L-shaped mounting plates are connected to both ends of the second spring, and the L-shaped mounting plates can be welded to the second spring. The L-shaped mounting plates facilitate the connection between the second spring and the guide groove 206 and the mortise hole 204. The L-shaped mounting plates can be connected to the guide groove 206 and the mortise hole 204 by welding or threading.

[0049] In other embodiments, the first elastic connector 104 and the second elastic connector 205 can also be springs or sheet springs, which can achieve the elastic connection of the first tenon 102 in the tenon guide groove 105 and the elastic connection of the mortise 204 and the mortise body 201.

[0050] refer to Figure 3 , Figures 5 to 8In this embodiment, the mortise member 204 includes a mortise portion 2041, a connecting portion 2042, and an unlocking guide groove 2043. A second mortise 203 is formed on the mortise portion 2041, the connecting portion 2042 is connected to the mortise portion 2041, and the unlocking guide groove 2043 is formed at the bottom of the connecting portion 2042 along a first direction, with the unlocking component 3 abutting against the unlocking guide groove 2043. Specifically, the mortise portion 2041 has a second mortise 203 extending along a second direction, i.e., the Y direction. One end of the connecting portion 2042 is connected to the mortise portion 2041, and the end of the connecting portion 2042 away from the mortise portion 2041 is used to connect with the second elastic connector 205. The unlocking guide groove 2043 is formed at the bottom of the connecting portion 2042, so the unlocking component 3, when pushed along the Y direction, can abut against the unlocking guide groove 2043. The unlocking guide groove 2043 extends along the first direction, i.e., the X direction, meaning that the extension direction of the unlocking guide groove 2043 is the same as the insertion direction of the first tenon 102 and the first mortise 202. During unlocking, the unlocking component 3 first pushes the mortise part 204 along the Y direction within the mortise guide groove 206, causing the second tenon 103 to disengage from the second mortise 203. At this time, the unlocking component 3 abuts against the unlocking guide groove 2043, thus the mortise part 204 has the function of moving along the X direction without releasing its abutting state with the unlocking component 3, continuously maintaining the separation between the second tenon 103 and the second mortise 203. After the second tenon 103 and the second mortise 203 are separated, the mortise component 2 is moved further in the X direction to further separate the first tenon 102 from the first mortise 202. At this point, the unlocking guide groove 2043 guides the unlocking component 3. Therefore, the separation and unlocking of the tenon component 1 and the mortise component 2 can be achieved.

[0051] refer to Figure 3 The unlocking component 3 includes a push-pull rod 301 and a third elastic connector 302. The tenon body 101 has a mounting hole 106 along the second direction. The push-pull rod 301 is fitted into the mounting hole 106 via the third elastic connector 302, and the position of the push-pull rod 301 corresponds to the position of the mortise 204. For example, one end of the third elastic connector 302 can be fixedly connected to the middle of the push-pull rod 301, and the other end of the third elastic connector 302 can be fixedly connected to the mounting hole 106. Therefore, the push-pull rod 301 can move elastically within the mounting hole 106, pushing the second mortise 203 away from the second tenon 103. Optionally, the third elastic connector 302 can also be a spring, a spring sheet, or an elastic rope, etc.

[0052] In this embodiment, the first mortise 202 and the mortise body 201 can be integrally formed, and the second tenon 103 and the tenon body 101 can be integrally formed. Of course, in some other embodiments, the first mortise 202 can also be detachably connected to the mortise body 201 through other parts, and the second tenon 103 and the tenon body 101 can also be detachably connected, for example, by using bolts.

[0053] Example 2

[0054] refer to Figures 1 to 10 This embodiment is similar to Embodiment 1, and can be found by referring to... Figure 9 and Figure 10 The difference lies in this embodiment, where the unlocking component 3 further includes a limiting member 303. The limiting member 303 is fixed in the mounting hole 106 and has a hole through which the push-pull rod 301 passes. The push-pull rod 301 has a limiting portion 3011. The third elastic connector 302 is a third spring, with one end abutting against the limiting member 303 and the other end abutting against the limiting portion 3011 of the push-pull rod 301. Specifically, the limiting portion 3011 extends radially from the middle of the push-pull rod 301. After the third spring is sleeved in the push-pull rod 301, one end abuts against the limiting portion 3011. A shoulder 1061 is also provided in the mounting hole 106. The shoulder 1061 abuts against the side of the limiting portion 3011 of the push-pull rod 301 away from the third spring, ensuring that the push-pull rod 301 is elastically connected in the mounting hole 106 and will not come out. The limiting component 303 is sleeve-shaped and is fixed in the mounting hole 106 by an interference fit between its outer circumferential surface and the mounting hole 106. Alternatively, it can be fixed by a threaded connection. This design of the unlocking component 3 facilitates disassembly, installation, and replacement of parts.

[0055] Example 3

[0056] refer to Figure 11 and Figure 12This embodiment provides an automatic cooking machine, including a pot body 4, a pot lid 5, a stirring robot 6, and a mortise and tenon connection structure as described in any of the above embodiments. The mortise body 201 of the mortise and tenon connection structure is internally connected to the pot lid 5, and the tenon body 101 of the mortise and tenon connection structure is connected to the stirring robot 6. The stirring robot 6 has an unlocking hole 601, and the unlocking component 3 extends through the unlocking hole 601 to the side away from the pot lid 5. Specifically, a first connecting post is provided at the bottom of the tenon body 101, which is connected to the center of the stirring robot 6. A second connecting post is provided at the top of the mortise body 201, which is connected to the inner side of the pot lid 5. The connection method can be a threaded connection. Preferably, the first connecting post passes through one end of the stirring robot 6 to form a handle. During assembly, the pot lid can be fixed with one hand, and the handle can be held with the other hand to engage the tenon body 101 and the mortise body 201. During disassembly, the handle can be held while the unlocking component 3 is pressed, and then the two can be disengaged by moving laterally. The mortise and tenon joint structure facilitates the disassembly and fixing of the pot lid 5 and the stir-frying robot 6. Compared with conventional fixed connections, it is easier to disassemble and clean, especially when the robot needs to be replaced for different stir-frying tasks.

[0057] In this preferred embodiment, an unlocking hole 601 is provided in the stir-frying robot 6, allowing the push-pull rod 301 of the unlocking component 3 to extend out of the unlocking hole 601 to the side away from the pot lid 5. It can be understood that the end of the push-pull rod 301 extending out of the unlocking hole 601 is the end of the push-pull rod 301 away from the mortise and tenon connection structure, that is, the end of the connecting rod used for pressing. This avoids the problem of difficulty in unlocking the pot lid 5 due to the narrow space between it and the stir-frying robot 6 after they are connected.
