[0002] An automatic stir-fry machine is a kitchen appliance that simulates the process of manual stir-frying through preset programs and automation technologies. Users can select recipes through a touch screen or a remote control device, and then the machine will automatically complete the entire process from heating, ingredient dispensing, stirring to cooking completion.

[0003] In existing stir-fry machines, there is an ingredient pushing mechanism. By inverting a meal box containing various ingredients into the ingredient pushing mechanism, the ingredient pushing mechanism is used to dispense the ingredients in stages, and then combined with a stir-frying mechanism to cook the dispensed ingredients to ensure the taste of the cooked dishes. However, some new users or children, out of curiosity, may open the stir-fry machine to check the cooking situation when they are not familiar with the cooking of the stir-fry machine. If the stir-fry machine is opened just when the ingredient pushing mechanism is operating, it is easy for the ingredient pushing mechanism to pinch the user's hand, and in this way, the safety factor of using the stir-fry machine is relatively low.

[0023] Please refer to Figure 1 , in an embodiment, a pinch prevention mechanism for a cooking machine includes a box body 1. A food placement area 2 is provided on the box body 1. A box cover 3 is rotatably provided on the box body 1 at the food placement area 2. A power-off component is provided on the box cover 3. A food pushing mechanism 4 is provided in the food placement area 2. A food feeding port 5 is opened on one side of the food placement area 2 away from the food pushing mechanism 4. A cooking component is provided below the food feeding port 5. The cooking component, the food pushing mechanism 4, and the power-off component are electrically connected to a control box provided inside the box body 1. The power-off component is used to cut off the power supply of the food pushing mechanism 4 and the cooking component when the box body 1 is opened.

[0024] Specifically, the food is placed in a lunch box with multiple compartments. By buckling the lunch box upside down in the food placement area 2 and using the intermittent movement of the food pushing mechanism 4 to push the lunch box, the segmented feeding of the food is realized;

[0025] Specifically, on the basis of the above embodiment, the power-off component includes a micro switch. A micro switch is provided on the box cover 3, and the micro switch is electrically connected to the control box.

[0026] It can be understood that by setting a power-off component on the box cover 3, that is, setting a micro switch, the micro switch can send a signal to the control box in time after the user opens the box cover 3, and the control box can be used to cut off the power of the food pushing mechanism 4 and the cooking component in time, which effectively avoids the situation where the user's hands are pinched by the food pushing mechanism 4 and the cooking component when they are in operation after the user opens the box cover 3, and the overall safety factor is higher.

[0027] For details, please refer to Figure 2 , Figure 3 , Figure 4 On the basis of the above embodiment, the food pushing mechanism 4 includes a first motor 401, a fixed frame 402, a pushing frame 403, and a screw rod 404. The box body 1 is provided with a first motor 401, and the output shaft of the first motor 401 is connected with the screw rod 404, the screw rod 404 is connected with the fixed frame 402, and the two ends of the fixed frame 402 are slidably arranged on the guide rod 405, and the pushing frame 403 is rotatably connected to the fixed frame 402. The intermittent rotation of the first motor 401 is utilized to realize the intermittent pushing of the pushing frame 403 when the screw rod 404 rotates intermittently, thereby realizing the segmented delivery of food.

[0028] For details, please refer to Figure 2 On the basis of the above embodiment, the cooking component includes a pot body 601, a frying spoon 602 and a second motor 603. The pot body 601 is arranged inside the box body 1 and is placed below the food inlet 5. The frying spoon 602 is arranged on the pot body 601. The frying spoon 602 passes through the pot body 601 and is connected to the output shaft of the second motor 603. The second motor 603 is used to drive the frying spoon 602 to rotate, so that the frying spoon 602 can stir-fry the food that falls into the pot body 601.

[0029] For details, please refer to Figure 1 On the basis of the above embodiment, it also includes a protrusion and a groove. The box cover 3 is provided with a protrusion, and the box body 1 is provided with a groove. The groove is adapted to the protrusion, and the groove is used for the user to insert his finger into and pry the box cover 3 to rotate. It can be understood that with the groove, the user does not need to find a suitable force point on the surface of the box cover 3, and can directly put his finger into the groove, so that the box cover 3 can be opened more quickly and conveniently.

[0030] Specifically, on the basis of the above embodiment, a sealing ring is further included. A sealing ring is arranged on one side of the box cover 3 close to the food placement area 2. The sealing ring is arranged to help increase the sealing performance.

[0031] In summary, by providing a micro switch on the lid 3, the opening and closing action of the upper lid can directly act on the operating rod of the micro switch. When the upper lid is closed, the contacts of the micro switch are closed, and the circuit forms a closed loop. At this time, the micro switch outputs a low level or a logic 0 signal; when the upper lid is opened, the operating rod of the micro switch is pushed, causing the contacts to separate and the circuit to break. At this time, the micro switch outputs a high level or a logic 1 signal. The level signal output by the micro switch is connected to the control box through a wire. There is program logic inside the control box, which can read these output states regularly or in real time. By using the control box to monitor the level change of the output of the micro switch, the power supply of the first motor 401 and the second motor 603 can be turned on and off in time after the lid 3 is opened, effectively avoiding the situation where the user's finger is clamped by the food pushing mechanism or the cooking component after the lid 3 is opened, and the overall safety factor is higher.

[0032] Please refer to Figure 1 , Figure 2 , Figure 4 , on the basis of the above embodiments, the present application also provides another implementation manner. In this embodiment, a micro switch is provided on the lid 3, and the positive wires of the first motor 401 and the second motor 603 are connected to the output end of the micro switch. When the contacts are closed (i.e., the lid 3 is in the closed state), the current can flow from the positive pole of the power supply through the micro switch to the positive poles of the motors, driving the first motor 401 and the second motor 603 to work; when the contacts are disconnected (i.e., the lid 3 is opened), the current path is cut off, and the first motor 401 and the second motor 603 stop working.

[0033] Through this design, once the lid 3 is opened, the micro switch will disconnect, causing the positive poles of the first motor 401 and the second motor 603 to be disconnected from the power supply, thereby stopping the movement and effectively preventing the occurrence of safety accidents such as pinching hands.

[0034] It should be noted that in this article, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, device, article or method including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, device, article or method. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, device, article or method including that element.

[0035] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present application by the same token.
