[0030] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0031] Example 1

[0032] like Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a food processor to prevent accidental operation, comprising: a pot body 1, a heating element 2, a lid 3, a drive element 4, a sensing element 5, a first blade 6, a second blade 7, a sensing element 8, and a controller. The heating element 2 is disposed at the bottom of the pot body 1. The lid 3 is detachably mounted on the pot body 1. The drive element 4 is located above or below the pot body 1, and the sensing element 5 is located above or below the pot body 1. The drive element 4 has a first output end 41 and a second output end 42 coaxially arranged. The sensing element 8 is disposed on the first blade 6. The first blade 6 and the second blade 7 are detachably and alternately disposed within the pot body 1, and the first blade 6 and the second blade 7 are movably connected to the first output end 41 and the second output end 42, respectively. The controller is electrically connected to the heating element 2, the drive element 4, and the sensing element 5. The controller controls whether the heating element 2 operates based on whether the sensing element 5 senses the sensing element 8.

[0033] In this embodiment, both the driving element 4 and the sensing element 5 are located above the pot body 1. Specifically, both the driving element 4 and the sensing element 5 are disposed on the lid 3. Of course, the driving element 4 can also be disposed above the pot body 1, and the sensing element 5 can be disposed below the pot body 1. The above is only one embodiment of this utility model and should not be considered as such.

[0034] When making paste using the food processor with anti-misoperation function, place the first blade 6 inside the pot 1, with the lower end of the first blade 6 fitted onto the mounting shaft at the bottom of the pot 1. Cover the pot with the lid 3, connecting the upper end of the first blade 6 to the first output terminal 41 of the drive unit 4. Start the food processor with anti-misoperation function, and the sensing element 5 detects the sensing element 8. The sensing element 5 sends a feedback signal to the controller, which then controls the heating element 2 to power on and heat the food inside the pot 1. Simultaneously, it controls the drive unit 4 to drive the first blade 6 to rotate. When grinding meat using the food processor with anti-misoperation function, place the second blade 7 inside the pot 1, with the lower end of the second blade 7 fitted onto the mounting shaft at the bottom of the pot 1. Cover the pot with the lid 3, connecting the upper end of the second blade 7 to the second output terminal 42 of the drive unit 4. Start the food processor with anti-misoperation function, and the sensing element 5 does not detect the sensing element 8. The sensing element 5 sends a feedback signal to the controller, which then controls the drive unit 4 to drive the second blade 7 to rotate, while the heating element 2 remains unpowered to prevent the heating element 2 from cooking the meat inside the pot 1.

[0035] Specifically, the heating element 2 mentioned above can be a heating plate.

[0036] Specifically, the aforementioned driving component 4 includes a drive motor and a gearbox. The output shaft of the drive motor is connected to the input end of the gearbox. The gearbox has a first output end 41 and a second output end 42 arranged coaxially, and the output speeds of the first output end 41 and the second output end 42 are different. It should be noted that the gearbox with the first output end 41 and the second output end 42 arranged coaxially is prior art and will not be described in detail here.

[0037] In practical applications, the sensing element 5 can be a micro switch, and the sensing element 8 can be a protrusion on the first cutter 6. When the upper end of the first cutter 6 is connected to the first output terminal 41 of the drive unit 4, the protrusion will trigger the micro switch, that is, the sensing element 5 will sense the sensing element 8. However, when the upper end of the second cutter 7 is connected to the second output terminal 42 of the drive unit 4, the micro switch will not be triggered, that is, the sensing element 5 will not sense the sensing element 8. Of course, the sensing element 5 can also be other switch structures, such as a limit switch.

[0038] In some preferred embodiments, the sensing element 5 is a Hall sensor, and the sensing element 8 is a magnet. By combining the Hall sensor with the magnet, not only can contactless sensing be achieved, but environmental interference, such as temperature changes, can also be avoided, resulting in better operational stability. Specifically, the distance between the sensing element 5 and the sensing element 8 is 0-10mm, thus ensuring the accuracy and sensitivity of the interaction between them.

[0039] In some preferred embodiments, the aforementioned sensing element 8 is disposed inside the first cutting tool 6. This technical solution, compared to disposing of the sensing element 8 outside the first cutting tool 6, avoids the possibility of the sensing element 8 colliding with other objects and falling off during tool installation or removal, ensuring that the sensing element 8 can accurately sense the first cutting tool 6. Specifically, the sensing element 8 can be integrally formed inside the first cutting tool 6.

[0040] In some preferred embodiments, the sensing element 8 described above is a ring magnet. Using a ring magnet as the sensing element 8 not only ensures a uniform magnetic force distribution, but also results in a closed magnetic circuit with low magnetic resistance and stronger anti-interference capability.

[0041] In practical applications, the aforementioned food processor designed to prevent accidental operation has a first control button and a second control button, both electrically connected to the controller. Specifically, when making a paste, the food processor is controlled via the first control button. Pressing the first control button energizes the sensing element 5. If the first blade 6 is placed inside the pot 1 at this time, the sensing element 5 senses the sensing element 8 and sends a signal back to the controller, which then controls the heating element 2 and the driving element 4 to operate. When mincing meat, the food processor is controlled via the second control button. Pressing the second control button energizes the driving element 4, which in turn drives the second blade 7 placed inside the pot 1 to rotate.

[0042] When a user makes a paste, the second blade 7 may be placed inside the pot 1. Since the second blade 7 does not have a sensing element 8, the heating element 2 will not be powered, preventing the paste from being made. To avoid this situation, in some preferred embodiments, the aforementioned food processor designed to prevent misoperation also includes a prompter electrically connected to the controller. When the drive unit 4 is rotated via the first control button, if the sensing element 5 does not detect the sensing element 8, the controller controls the prompter to issue a reminder. Specifically, the prompter can be a speaker, which can provide a voice prompt when the user uses the second blade 7 while making the paste, alerting the user to the incorrect use of the blade.

[0043] In some preferred embodiments, the lid 3 has a downwardly recessed portion 31 in the middle. When the lid 3 is placed on the pot body 1, the recessed portion 31 is located inside the pot body 1, and at least a portion of the drive member 4 and the sensing element 5 are located within the recessed portion 31. This technical solution lowers the center of gravity of the food processor, preventing accidental operation, thus ensuring stable operation and reducing the likelihood of shaking.

[0044] In practical applications, the outer wall of the pot body 1 is provided with a side lug, and a first coupler is provided on the side lug. The first coupler is electrically connected to the power supply unit at the bottom of the pot body 1. A second coupler is provided on the lid 3, and the second coupler is electrically connected to the drive unit 4, the sensing element 5, and the controller. Specifically, the power supply unit is connected to the mains power to power the food processor.

[0045] Example 2

[0046] like Figure 4 and Figure 5As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, both the driving component 4 and the sensing element 5 are located below the pot body 1. In specific applications, a base 9 and a mounting base 10 detachably connected to the base 9 are connected to the bottom of the pot body 1. The driving component 4 is disposed inside the mounting base 10, and both the first output end 41 and the second output end 42 are exposed outside the mounting base 10. The sensing element 5 is disposed inside the base 9. A rotating shaft 11 is provided on the pot body 1. One end of the rotating shaft 11 extends into the pot body 1 and is connected to the first cutter 6 or the second cutter 7. The other end of the rotating shaft 11 is exposed outside the base 9. When the base 9 is connected to the mounting base 10, the other end of the rotating shaft 11 is connected to the first output end 41 or the second output end 42.

[0047] Specifically, the other end of the rotating shaft 11 can be connected to the first output end 41 or the second output end 42 via a coupling 1414.

[0048] like Figure 6 As shown, in a specific application, the base 9 is provided with a first electrical connector 12, which is electrically connected to the heating element 2, the sensing element 5, and the controller. The mounting base 10 is provided with a second electrical connector 13, which is electrically connected to the driving element 4 and the power supply unit on the mounting base 10. When the base 9 and the mounting base 10 are connected, the first electrical connector 12 and the second electrical connector 13 are electrically connected. Specifically, both the first electrical connector 12 and the second electrical connector 13 are couplers.

[0049] Example 3

[0050] like Figure 7 and Figure 8 As shown, the difference between this embodiment and Embodiment Two is that there are two of each: the pot body 1, the sensing element 5, the base 9, and the rotating shaft 11. The two bases 9 are alternately connected to the mounting base 10 so that the other ends of the two rotating shafts 11 are respectively connected to the first output terminal 41 or the second output terminal 42. Specifically, the diameters of the other ends of the two rotating shafts 11 are different. The other end of one rotating shaft 11 can only be connected to the first output terminal 41, and the other end of the other rotating shaft 11 can only be connected to the second output terminal 42. In this way, when different speeds are required, the pot body 1 can be directly replaced, which is more convenient and faster than replacing the coupling 14.

[0051] In summary, in one or more embodiments of this utility model, the food processor of this utility model prevents misoperation by determining whether the blade is installed correctly through whether the sensing element detects the sensing element, so as to avoid using the wrong blade and thus avoid misoperation that leads to failure to achieve the expected results.

[0052] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
