Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing equipment, specifically to a switch structure for a food processing machine. Background Technology
[0002] Food processors, such as blenders, meat grinders, and food processors, are indispensable tools in modern kitchens, greatly simplifying the processes of cutting, mixing, grinding, and emulsifying ingredients. The core function of these devices relies on their drive motors, and the key component controlling the motor's start / stop and operating status is the device's power switch.
[0003] In existing technologies, to achieve different function controls, equipment manufacturers generally use a solution of setting two or more independent physical buttons. Users need to identify and press different independent buttons to trigger the corresponding functions.
[0004] However, this design, where each button has its own independent spring and switching assembly, has inherent limitations. First, from the perspective of structural complexity and manufacturing cost, multiple independent springs, switch contacts, button housings, and related assembly structures significantly increase the number of parts, mold costs, and assembly processes. Each button assembly requires precise positioning and independent sealing or dustproofing measures, further increasing manufacturing complexity and cost. Furthermore, multiple independent components also mean more potential points of mechanical failure, reducing the overall system reliability and potentially affecting the consistency of the operating feel due to accumulated component tolerances. Moreover, the dual-button design is not efficient in space utilization, occupying a large area of the panel and hindering device miniaturization or design simplification.
[0005] For example, application number 202323007250.1 (authorization announcement number CN221044810U) discloses a meat grinder, including a cup body; a machine head located above the cup body, with a motor and a gear switch installed in the machine head; a blade assembly connected to the output end of the motor, extending into the cup body; a control panel located in the machine head, electrically connected to the motor to control the motor's operation or shutdown; a micro switch located in the machine head, triggerable or deactivated by the gear switch, electrically connected to the control panel; and a timer located in the machine head, electrically connected to the control panel or the micro switch. This invention features two micro switches and corresponding buttons, resulting in a complex structure, high manufacturing costs, and a large footprint.
[0006] Therefore, existing food processing machines need to be improved. Utility Model Content

[0033] When the main unit is adapted to the cup lid state, the trigger rib and the convex rib abut against each other, the switch linkage rises, and drives one side of the trigger surface of the switch bracket to rotate upward. The upper conductive component approaches the button. After the button is pressed, the button is pressed down, which drives the upper conductive component to press down, so that the upper conductive component contacts the first conductive part or the second conductive part, and the motor starts.

[0036] In order for the switch linkage to extend downward when the main unit is detached from the cup lid, preferably, a spring is provided between the switch bracket and the button.

[0058] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0059] Example 1
[0060] like Figure 1-10 The image shows a preferred embodiment of the present invention. The food processor switch structure includes a cup body 1, a rotating blade 11, a cup lid 12, and a main unit 2.
[0061] The rotating blade 11 is located inside the cup body 1 and has a central shaft 111; the cup lid 12 is closable on the port of the cup body 1 and has a through hole 121 for the upper end of the central shaft 111 to extend out; the upper end face of the cup lid 12 has a rib 122, and the housing 21 is provided with a switch linkage 26 that can be raised and lowered, the bottom end of which forms a first trigger rib 261 that cooperates with the rib 122.
[0062] The main unit 2 is detachably mounted on the cup lid 12 and can drive the central shaft 111 to rotate; the main unit 2 includes a housing 21, a motor 22, a button 23, an upper conductive component 24, a lower conductive component 25, a switch linkage 26, and a switch bracket 27.
[0063] like Figure 1 and 2 As shown, the housing 21 is detachably mounted on the cup lid 12; the motor 22 is located inside the housing 21, and its power output end is connected to the central shaft 111; the housing 21 includes a lower housing 213 and an upper housing 212 located at the upper port of the lower housing 213. The bottom of the housing 21 is provided with a groove 211 that matches the protruding rib 122, and the first trigger rib 261 is located in the groove 211. The motor 22 is located inside the lower housing 213, and the switch linkage 26 is partially located inside the lower housing 213, with its upper end extending from the adapter hole 215 of the upper housing 212 and thus located inside the upper housing 212.
[0064] Button 23 is located on housing 21. Specifically, button 23 is movably located on the upper end face of upper housing 212, and the lower end face of button 23 extends downward to form a pressing post 231.
[0065] like Figure 4 As shown, the upper conductive element 24 is disposed inside the housing 21 and located below the button 23; the first conductive part 251 and the second conductive part 252 are spaced apart from each other and are both disposed below the upper conductive element 24;
[0066] The lower conductive component 25 includes a first conductive part 251 and a second conductive part 252. Both the first conductive part 251 and the second conductive part 252 are metal pieces that are linked to the motor 22 and spaced apart from each other. Pressing down the button 23 causes the upper conductive component 24 to press down, making it contact the first conductive part 251 or the second conductive part 252, thereby putting the motor 22 into a first operating mode or a second operating mode. The upper conductive component 24, the first conductive part 251, and the second conductive part 252 are housed within the upper housing 212 via corresponding connecting brackets 29. Contacts 241 are provided on both sides of the lower end face of the upper conductive component 24; the first conductive part 251 and the second conductive part 252 correspond to the two contacts 241 of the upper conductive component 24. A diode 253 electrically connected to the first conductive part 251 and the second conductive part 252 is provided between them. During normal operation, diode 253 is in reverse cutoff state; at the moment of power disconnection, the coil of motor 22 will generate reverse electromotive force, and the current will try to be discharged through the spring contact 241, causing arcing between the contacts 241. At the moment of disconnection, the current generated by the reverse electromotive force will be forward conducted through diode 253 to form a discharge circuit, preventing the current from forcibly passing through the gap of contacts 241 and generating an arc.
[0067] The upper conductive element 24 is a sheet-like conductive element fixed in the middle to the switch bracket 27, such as... Figure 10 As shown, the upper conductive element 24 is bent on both sides to be elastic. In other embodiments, an elastomer can be added below the upper conductive element 24 to help it rebound.
[0068] The switch bracket 27 is rotatably disposed within the housing 21, specifically, it is rotatably disposed within the upper housing 212, such as... Figure 4 and Figure 9 As shown, the switch bracket 27 is located below the button 23 and has a trigger surface 271 on one side and a rotating shaft 272 on the other side; the upper shell 212 has a connecting hole 214 corresponding to the rotating shaft 272; the top end of the switch linkage 26 forms a second trigger rib 262 that mates with the trigger surface 271. The upper conductive element 24, the first conductive part 251, and the second conductive part 252 are all provided on the switch bracket 27; the switch bracket 27 has a mounting groove 274 for mounting the spring 28 and a pressing hole 273 for the pressing post 231 to extend into. The spring 28 is located on the outer periphery of the pressing post 231 and within the mounting groove 274. The pressing post 231 extends from the pressing hole 273 to fit the upper conductive element 24. The spring 28 always forces one side of the trigger surface 271 of the switch bracket 27 to have a downward rotation tendency, thereby forcing the switch linkage 26 to always remain in a downward extended state.
[0069] The working principle of this embodiment is as follows:
[0070] like Figure 5As shown, when the host 2 is detached from the cup lid 12, the first trigger rib 261 extends downward.
[0071] When the trigger surface 271 of the switch bracket 27 rotates downward, the upper conductive part 24 moves away from the button 23. After the button 23 is pressed, the gap between the bottom surface of the button 23 and the switch bracket 27 prevents the upper conductive part 24 from contacting the first conductive part 251 and the second conductive part 252. The motor 22 does not start, and the rotating blade 11 remains stationary.
[0072] like Figure 6 As shown, when the main unit 2 is adapted to the cup lid 12, the trigger rib and the protruding rib 122 abut against each other, the switch linkage 26 rises, causing one side of the trigger surface 271 of the switch bracket 27 to rotate upwards, and the upper conductive element 24 approaches the button 23, as shown. Figure 7 The right button 23 and Figure 8 As shown, after pressing button 23, button 23 presses down, causing the upper conductive part 24 to press down, making the upper conductive part 24 contact the first conductive part 251 or the second conductive part 252. The motor 22 starts, and the rotating blade 11 rotates.
[0073] When the upper conductive component 24 presses down to contact the first conductive part 251, the motor 22 is in the first working mode: vegetable chopping mode;
[0074] The upper conductive element 24 presses down to contact the second conductive part 252, and the motor 22 is in the second working mode: meat grinding mode; the speed of the motor 22 in the first working mode is lower than that in the second working mode, therefore, the speed of the rotating blade 11 in the first working mode is lower.
[0075] Example 2
[0076] like Figure 11 As shown, the difference between this embodiment and Embodiment 1 is that the lower conductive component 25 further includes a circuit board 254. The circuit board 254 has a first conductive portion 251 and a second conductive portion 252, which are copper conductive discs, on its top. A diode 253 is disposed on the circuit board 254 and electrically connected to the first conductive portion 251 and the second conductive portion 252. The upper conductive component 24 is fixed in the middle to the lower conductive component 25. In this embodiment, the lower conductive component 25 and the circuit board 254 are integrated, thereby enabling automated installation through the circuit board 254. Other structural details of this embodiment are referenced in Embodiment 1.
[0077] Example 3
[0078] like Figure 12-14As shown, the difference between this embodiment and Embodiment 2 is that the switch bracket 27 and the switch connecting rod 26 are integrated, and the spring 28 is located inside the upper shell 212, thereby enabling the button 23 to reset. The conductive element 24 is fixed in the middle to a metal sheet with bent ends on the lower conductive element 25, which has elasticity. The reset force of the upper conductive element 24 drives the switch bracket 27 and the switch connecting rod 26 to move downward through the lower conductive element 25. Figure 14 As shown, the switch bracket 27 extends downward on both sides to form latches 275 that engage with the circuit board 254, so that the circuit board 254 rises and falls with the rotation of the switch bracket 27.
[0079] When the main unit 2 is detached from the cup lid 12, the first trigger rib 261 extends downward, and the downward movement of the switch linkage 26 causes the one-piece molded switch bracket 27 to rotate downward on the side close to the switch linkage 26, and the upper conductive part 24 and the lower conductive part 25 move away from the button 23.
[0080] When the host 2 is adapted to the cup lid 12 state, the trigger rib and the protruding rib 122 abut against each other, the switch linkage 26 rises, and drives the switch bracket 27 to rotate upward on the side close to the switch linkage 26, and the upper conductive part 24 and the lower conductive part 25 approach the button 23.
