[0002] An automatic cooking machine is an intelligent kitchen device that can replace manual labor in cooking ingredients. To prevent users from being scalded by touching the heated pot body during cooking, the cooking machine is usually in a locked state during cooking, that is, a child lock.

[0003] The basic structure of the existing child lock usually includes an electromagnetic coil and an iron block (or called a lock core). When the electromagnetic coil is energized, a magnetic field will be generated to attract the iron block, thereby fixing the locking device in a certain position. When powered off, it will reset according to the gravity of the lock core itself. However, long-term power-on may cause the electromagnetic coil to heat up. If the heat dissipation is not good or the working environment temperature is high, it may cause the electromagnetic lock to overheat and be damaged.

[0004] Therefore, there is an urgent need for a technical problem to be solved by a child lock mechanism for an automatic cooking machine.

[0026] Please refer to Figure 1 , Figure 2 , Figure 3 , in an embodiment, a child lock mechanism of an automatic cooking machine includes a box body 1 and a box door 2. The box door 2 is rotatably connected to the box body 1. An electromagnetic coil 3 is provided on the box body 1. The electromagnetic coil 3 is electrically connected to a controller. A clamping member is slidably provided on one side of the box body 1 where the electromagnetic coil 3 is located. The clamping member is connected to an elastic member provided on the box body 1. One end of the clamping member is clamped and connected to the box door 2.

[0027] Further, the clamping member includes a lock housing 6 and a lock core 5. The lock housing 6 is provided on the box body 1. The other end of the lock core 5 passes through the lock housing 6, and the lock core 5 can slide relatively on the lock housing 6. The lock core 5 is used to connect to the box door 2.

[0028] It can be understood that a controller (not shown in the figure) is provided in the box body 1. When the controller is powered on, a magnetic field is generated after the electromagnetic coil 3 is energized by the controller, driving the lock core 5 to move. Specifically, a mechanical structure (not shown in the figure) is provided inside the lock case 6. The mechanical structure can be a motor and a worm and gear structure. The output end of the motor is connected to the turbine, the turbine meshes with the worm, and both ends of the worm are connected to the lock core 5. By energizing the motor and the electromagnetic coil 3 with the controller, the turbine is driven to drive the worm to rotate, and then the worm drives the lock core 5 to move. When the power supply to the motor and the electromagnetic coil is stopped, the lock core 5 is kept stationary at the current position by the structural cooperation between the turbine and the worm. In this way, there is no need to energize the electromagnetic coil 3 for a long time, effectively avoiding the damage of the electromagnetic coil 3, not only saving energy and prolonging the service life of the electromagnetic coil 3, but also increasing stability. When unlocking is required, the motor and the electromagnetic coil are energized in the reverse direction, which is more convenient to operate as a whole, reduces the risk of failure, and improves the overall performance and user experience of the device.

[0029] Specifically, please refer to Figure 1 , Figure 5 , Figure 6 , on the basis of the above embodiment, it further includes a Hall sensor 10 and a plurality of magnets 11. The Hall sensor 10 is provided on the box body 1, and the Hall sensor 10 is electrically connected to the controller. A plurality of magnets 11 are provided on the box door 2, and the Hall sensor 10 is used to detect the magnetic field change of the plurality of magnets 11.

[0030] It can be understood that when the box door 2 is closed, the magnet 11 on the box door 2 approaches the Hall sensor 10, generating a magnetic field change, triggering the Hall sensor 10. The Hall sensor 10 converts the detected magnetic field change into an electrical signal and sends it to the controller. The controller determines whether the box door 2 is in a tightly closed state according to the received signal.

[0031] Specifically, please refer to Figure 2 , Figure 3 , Figure 4 , on the basis of the above embodiment, it further includes a connecting block 4. The connecting block 4 is slidably provided on the box body 1. One end of the connecting block 4 is connected with an elastic member, and the other end of the connecting block 4 is connected with the clamping member. At the same time, a placement groove is provided on the box body 1, and a buckle plate 8 is slidably provided in the placement groove. The buckle plate 8 passes through the box body 1 and is connected with the connecting block 4.

[0032] It can be understood that by setting the connecting plate 4, the buckle plate 8 and the placement groove, an emergency unlocking method can be provided when the cooking machine suddenly loses power. The specific operation is to manually move the buckle plate 8, and the buckle plate 8 drives the connecting block 4 to move in the placement groove, so that when the connecting block 4 moves, it drives the lock core 5 to move to achieve the unlocking action. Through the above settings, the cooking machine is further provided with protection.

[0033] Specifically, please refer to Figure 2 , Figure 3 , based on the above embodiment, the elastic member is a tension spring 7. One end of the tension spring 7 is connected to the box body 1, and the other end of the tension spring 7 is connected to the connecting block 4. It can be understood that the tension spring 7 is used to maintain the locked state, and there is no need to energize the electromagnetic coil 3 for a long time, reducing the damage to the electromagnetic coil 3.

[0034] Specifically, please refer to Figure 2 , Figure 3 , Figure 5 , based on the above embodiment, it further includes a locking plate 9. The locking plate 9 is provided on the box door 2, and a through hole is opened on the locking plate 9, and the through hole is adapted to the lock core 5. It can be understood that the lock core 5 extends into the through hole in the locking plate 9 to achieve the locking of the box door 2. Using this locking method to replace the traditional lock shell, there is no need to energize the electromagnetic coil 3 for a long time, and the overall structure is simple and more practical.

[0035] Specifically, based on the above embodiment, it further includes a speaker (not marked in the figure). The speaker is provided on the box body 1, and the speaker is electrically connected to the controller.

[0036] It can be understood that by setting the speaker, it can be used to detect the closed state of the box door 2. When the box door 2 is not closed tightly, it can emit a sound in time to prompt the user, avoiding the oil fume generated during cooking from being discharged from the gap between the box door 2 and the box body 1 and affecting the cooking environment.

[0037] In summary, when the child lock mechanism of an automatic cooking machine is in use, the Hall sensor 10 is utilized to detect whether the cabinet door 2 is in a closed state. When the cabinet door 2 is not in a closed state, a prompt signal is promptly emitted through the speaker. When it is necessary to lock the door, the electromagnetic coil 3 and the motor are energized forward. The lock core 5 extends into the through hole on the locking plate 9, and then the power is cut off. The lock core 5 remains stationary at its current position. At this time, the lock core 5 clamps the cabinet door 2; when the cooking of the dishes in the cooking machine is completed, the controller controls the speaker to emit a prompt signal. When it is necessary to open the door, the controller energizes the motor and the electromagnetic coil 3 in the reverse direction. The lock core 5 moves reversely and disengages from the through hole on the locking plate 9, and then the power is cut off again. At this time, the lock core 5 remains stationary at its current position, completing the unlocking action of the cabinet door 2. Subsequently, the user can manually open the cabinet door 2 to take out the cooked dishes in the cooking machine. During the entire locking process, there is no need to energize the electromagnetic coil 3 for a long time, effectively avoiding problems such as damage to the electromagnetic coil 3 caused by overheating due to long-term power-on, and effectively improving the service life of the electromagnetic coil 3; at the same time, in order to prevent the cabinet door 2 from being unable to be opened due to sudden power failure, this application also provides a placement groove and a buckle plate 8 on the cabinet body 1. In the case of power failure of the cooking machine, the user can move the buckle plate 8 to manually disengage the lock core 5 inside the cabinet body 1 from the locking plate 9 and then open the cabinet door 2, providing an emergency unlocking method, which is more flexible and reliable as a whole.
