[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1:

[0028] See also Figures 1 to 7As shown, a food processor with a safety mechanism includes a main body 1 and a container 2 and a motor 3 arranged in the main body 1. A heating element 4 is provided at the bottom of the container 2, and the heating element 4 can be a heating plate. The motor 3 is assembled on the lower side of the container 2, and its transmission shaft extends into the inner cavity of the container 2 and is connected to a stirring blade 5. A pressure relief port 201 communicating with the inner cavity of the container 2 is provided on the top of the container 2, and a top cover 6 is detachably connected to the pressure relief port 201. A top cover receiving portion is provided on the main body 1, and a safety sensing element connected in series to the working circuit is provided on the top cover receiving portion. A sensor element or a sensor portion is provided on the top cover 6. When the top cover 6 is placed on the top cover receiving portion, the sensor element or the sensor portion acts on the safety sensing element at the corresponding position, so that the safety sensing element generates a working signal.

[0029] This food processor requires the top cover 6 as the switch key for the working circuit, which can ensure that the pressure relief vent can be fully opened during use. At the same time, it meets the abnormal test requirements of the safety regulations. It is simple to operate, has clever logic, is low in cost, and provides better safety and user experience.

[0030] The top of the top cover 6 is provided with a hanging ear 61, and the hanging ear 61 constitutes the sensing part; the hanging ear 61 is added to the top cover 6, on the one hand, so that a sensing element is provided in the hanging ear 61 or used as a sensing part, and on the other hand, when the food processor is used as a soymilk maker, after the soymilk is made, the top cover can be covered on the pressure relief port 201, which is convenient for consumers to extract the food processor, thereby improving the portability of the food processor.

[0031] The container 2 includes a cup body 21 and a cup cover 22. The cup body 21 is fixedly connected to the body 1. The cup cover 22 is detachably connected to the cup mouth of the cup body 21. A cover mouth 23 forming a pressure relief port 201 is extended from the cup cover 22. The top cover 6 is detachably connected to the cover mouth 23.

[0032] After the cup cover 22 is removed from the cup body 21, the cup mouth of the cup body 21 is opened, which is convenient for putting ingredients in before work. During work, the cup cover 22 can prevent the slurry from splashing out. The pressure relief port 201 is set on the cup cover 22. When the food processor takes the soy milk out, the pressure relief port 201 can be used as a pouring port, which is more convenient for users to pour out the soy milk.

[0033] The top cover receiving portion includes a switch seat 10 provided on the outer wall of the body 1, and a safety sensing element is provided in the switch seat 10. The safety sensing element is a micro switch 11. A hook groove 12 is provided on the upper side of the micro switch 11. The hanging ear 61 is hung in the hook groove 12. The cup cover 22 extends with a touch plate 24 corresponding to the hook groove 12. After the cup cover 22 is installed in place, the touch plate 24 presses the hanging ear 61 to move and trigger the switch key 111 of the micro switch 11;

[0034] In this embodiment, the safety sensing element is implemented using the physical structure of a micro switch 11 to prevent the electronic switch from failing or being triggered by mistake due to external influences.

[0035] The switch base 10 is provided with a guide channel 101 , in which a transmission member is movably provided. One end of the transmission member is adjacent to or against the switch key 111 of the micro switch 11 , and the touch plate 24 presses the other end of the transmission member.

[0036] The principle of the safety mechanism is: the top cover 6 acts as a switch key. Before starting the food processor, the user needs to hang the top cover 6 in the hook slot 12 through the hanging ear 61, and then screw the cup cover 22 onto the cup mouth of the cup body 21. During the rotation of the cup cover 22, the touch plate 24 of the cup cover 22 cuts into the top of the hanging ear 61 and presses the hanging ear 61, so that the hanging ear 61 successively drives the transmission part and the switch key 111 of the micro switch 11, thereby generating a working signal to connect the working circuit; this safety mechanism can ensure that the top cover 6 is removed from the pressure relief port 201, and secondly, it can ensure that the cup cover 22 is installed on the cup mouth, killing two birds with one stone, thereby meeting the abnormal test requirements in the safety regulations.

[0037] The transmission member includes an elastic sealing gasket 13, which is connected to the bottom surface of the hook groove 12, and a touch-pressure column 131 extending from the bottom of the elastic sealing gasket 13 and penetrating into the guide channel 101. The bottom of the touch-pressure column 131 presses against the switch key 111, and a convex surface 132 is provided on the pad surface of the elastic sealing gasket 13 corresponding to the touch-pressure column 131; the elastic sealing gasket 13 can seal the guide channel 101 to prevent liquid from flowing from the guide channel 101 into the switch base 10 and contacting the micro switch 11, thereby causing damage to the micro switch 11, and the convex surface 132 helps to increase the pressing depth of the touch plate 24 to ensure that the micro switch 11 is triggered.

[0038] When the elastic sealing gasket 13 is installed, a positioning column 133 and an undercut column 134 extend from the left and right sides of the touch-pressure column 131 respectively. The switch base 10 is provided with a positioning hole 102 and a buckle hole 103 corresponding to the positioning column 133 and the undercut column 134 respectively. The positioning column 133 cooperates with the positioning hole 102, and the undercut column 134 cooperates with the buckle hole 103, so that the elastic sealing gasket 13 is connected to the hook groove 12.

[0039] The cup cover 22 is circumferentially screwed on the cup mouth of the cup body 21, and a side protrusion 25 is extended corresponding to the switch seat 10. The touch plate 24 is connected to the bottom surface of the side protrusion 25. The hook groove 12 is provided with an incision 121 corresponding to the screw-in direction of the touch plate 24. The touch plate 24 is provided with an inclined incision surface 241 on the side facing the incision 121; in addition to the inclined setting, the inclined incision surface 241 can also be an arc-shaped setting. When the cup cover 22 rotates circumferentially, the convex surface 132 can be squeezed downward by the inclined incision surface 241, thereby triggering the micro switch.

[0040] The outer wall surface of the cover mouth 23 is provided with an external thread portion 231, and the inner wall surface of the top cover 6 is provided with an internal thread portion 62. The top cover 6 is screwed to the cover mouth 23 through the external thread portion 231 and the internal thread portion 62. The structure is simple and the top cover 6 is convenient for disassembly and assembly.

[0041] The inner top of the top cover 6 is provided with a sealing groove, in which a sealing ring 14 is embedded. After the top cover 6 and the cover mouth 23 are screwed together, the sealing ring 14 elastically presses against the top edge of the cover mouth 23 and seals the pressure relief port 201. Since the food processor needs to be carried outside, the sealing ring 14 is used to seal the pressure relief port 201 to prevent leakage of the pressure relief port 201.

[0042] The elastic sealing gasket 13 is a "U"-shaped structure, and the middle of the bottom surface of the hook groove 12 is higher than the two ends, and the inner side is higher than the outer side; the elastic sealing gasket 13 of this structure helps to quickly drain water dripping into the hook groove 12.

[0043] In this embodiment, the cup cover 22 is made of a transparent material, such as glass or plastic; the cup body 21 is made of a metal material, such as stainless steel. Example 2:

[0044] The difference between the second embodiment and the first embodiment is that: Figure 8 As shown, a sensor element is provided in the ear 61, specifically: the top cover receiving portion includes a hook 7 connected to the outer wall of the main body 1, and the ear 61 is hung on the hook 7; a safety sensing element is provided in the hook 7, the safety sensing element is a Hall switch 8, and the sensor element is a magnet block 9. When this structure is in use, the top cover 6 is directly hung on the hook 7 through the ear 61. When the Hall switch 8 senses the magnet block 9, a working signal is generated to connect the working circuit.
