Description
Technical Field
[0001] This utility model relates to the field of mixer technology, and more specifically, to a mixer rotary switch structure and a mixer. Background Technology
[0002] Existing food blenders have the function of blending food and mainly include: a body with a rotary drive, a set of blending blades driven by the rotation of the body, and a blending cup detachably mounted on the body. In use, food is placed in the blending cup, which is then connected to the body. The blender is then turned on to supply power, and the blending blades on the body chop and blend the food. Some existing food blenders control the machine's start / stop using a rotary switch structure on the body. To start, the circumferential rotation of the rotary switch activates the corresponding switch contacts, thus starting the blender; to stop, the rotary switch returns to its original position.
[0003] Existing rotary switch structures are complex and have high production costs. In addition, a transmission component is set between the rotary table and the switch element. When the rotary table rotates, the transmission component pushes the contacts of the switch element to actuate the switch element. The aforementioned transmission component contains many parts, has a complex structure, and has high production costs. The large number of parts in the transmission component also leads to poor accuracy and stability in the transmission process, resulting in poor reliability. Furthermore, some existing rotary switches have limited functionality, with only one control mode (jog or continuous operation), resulting in a poor user experience. Utility Model Content
[0004] To address at least one of the aforementioned problems, this utility model provides a turntable switch structure for a mixer, comprising: a body and a turntable rotatably mounted on the body, the turntable rotating in its circumferential direction; a switch and a transmission rod mounted on the body; the transmission rod slidably positioned between the switch and the turntable; a guide slope on the turntable; a trigger portion on the switch; one end of the transmission rod positioned on one side of the trigger portion; and the other end positioned on one side of the guide slope. When the turntable is rotated by an external force, the transmission rod slides through the guide slope, causing one end of the transmission rod to push the trigger portion to actuate. This turntable switch structure for a mixer uses only one transmission rod between the turntable and the switch, resulting in fewer transmission parts, a simpler structure, lower production costs, and more stable and reliable transmission, thereby improving the accuracy and stability of the switch action. It achieves both intermittent and continuous operation of the switch through a single turntable, meeting different user control needs and providing a superior user experience.
[0005] Optionally, the transmission rod slides vertically, with its upper end positioned on one side of the guide slope and its lower end positioned on the upper side of the trigger portion.
[0006] Optionally, the machine body is provided with a first mounting slot and a second mounting slot, the first mounting slot and the second mounting slot are distributed in the vertical direction, and the transmission rod is slidably placed in the first mounting slot and the second mounting slot in the vertical direction.
[0007] Optionally, an elastic element is provided between the transmission rod and the machine body. When the transmission rod slides, it has a first direction to push the trigger part and a second direction to reset the trigger part. The first direction is opposite to the second direction, and the elastic force of the elastic element acting on the transmission rod is in the same direction as the second direction.
[0008] Optionally, the transmission rod is provided with an annular flange, the elastic element is a compression spring, one end of the elastic element abuts against the lower side of the annular flange, and the other end of the elastic element abuts against the machine body.
[0009] Optionally, the guide slope includes a first guide slope and a second guide slope. The upper part of the transmission rod is provided with a third guide slope corresponding to the first guide slope and a fourth guide slope corresponding to the second guide slope.

The turntable is provided with a second positioning groove for positioning the upper end of the transmission rod. When the turntable rotates, it has a first rotation direction and a second rotation direction. When the turntable rotates in the first rotation direction, the upper end of the transmission rod slides relative to the first guide slope and is guided into the second positioning groove. When the turntable rotates in the second rotation direction, the upper end of the transmission rod slides relative to the second guide slope.
[0010] Optionally, the upper end of the transmission rod is provided with a first arc-shaped portion, and the turntable is provided with a second arc-shaped portion for guiding / exiting the first arc-shaped portion into / out of the second positioning groove.
[0011] Optionally, the switch is a micro switch, the triggering part is a triggering plate, and a bearing is provided between the machine body and the turntable. The bearing includes an inner rotating ring and an outer rotating ring that can rotate relative to each other.

[0013] Compared to existing technologies, this utility model's rotary switch structure for a mixer features only one transmission rod between the turntable and the switch. This reduces the number of transmission parts, simplifies the structure, lowers production costs, and ensures more stable and reliable transmission, thereby improving the accuracy and stability of the switch's operation. The turntable enables both jogging and continuous operation of the switch, meeting diverse user control needs and providing a superior user experience. The machine body has a first mounting groove and a second mounting groove, preventing horizontal displacement of the transmission rod during sliding and ensuring smooth operation of the switch. When the turntable rotates in the first rotation direction, the upper end of the transmission rod slides relative to the first guide slope and is guided into the second positioning groove. Positioning: When the turntable switch is released, it is in the closed state, thus enabling the continuous operation mode. Power is cut off by simply rotating the turntable back to the second rotation direction, making operation convenient. When the turntable rotates in the second rotation direction, the upper end of the transmission rod slides relative to the second guide slope, maintaining the turntable's rotational position. The trigger state of the trigger unit is manually maintained, enabling the jog mode. In jog mode, power is cut off by simply releasing or resetting the turntable, making it easy to use. The fifth and sixth guide slopes reduce the assembly difficulty and cost of the bearing assembly. Bearings are installed between the machine body and the turntable, ensuring smooth turntable rotation.

Detailed Implementation
[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0027] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.
[0028] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
[0029] See Figures 1-10This utility model provides a turntable switch structure for a mixer, including: a body 1 and a turntable 2 rotatably mounted on the body 1. The turntable 2 has a handle 24 for easy rotation by the user. The turntable 2 rotates in its circumferential direction. The body 1 has a switch 3 and a transmission rod 4, which slides between the switch 3 and the turntable 2. The turntable 2 has a guide slope 5. The switch 3 has a trigger part 301; pressing the trigger part 301 causes the switch 3 to close and energize. One end of the transmission rod 4 is positioned on the trigger part 301. On one side, the other end of the transmission rod 4 is placed on the side of the guide slope 5; when the external force rotates the turntable 2, the transmission rod 4 is driven to slide through the guide slope 5, so that one end of the transmission rod 4 pushes the trigger part 301 to act; the turntable switch structure of this utility model has only one transmission rod between the turntable and the switch, with fewer transmission parts, simple structure, low production cost, and more stable and reliable transmission, thereby improving the accuracy and stability of the switch action; the function of switching inching and continuous operation can be realized through a turntable, meeting different control needs of users and providing a good user experience.
[0030] See Figures 1-5 The transmission rod 4 slides vertically, with its upper end positioned on one side of the guide slope 5 and its lower end positioned on the upper side of the trigger part 301. Rotating the turntable drives the transmission rod 4 to slide vertically, thereby actuating the switch. The body 1 is provided with a first mounting groove 101 and a second mounting groove 102, distributed vertically. The first mounting groove 101 is located directly above the second mounting groove 102. The transmission rod 4 slides vertically within the first mounting groove 101 and the second mounting groove 102. Both the first and second mounting grooves are through grooves, preventing horizontal displacement of the transmission rod 4 during sliding, ensuring smooth sliding and thus smooth switch operation. An elastic element 6 is provided between the transmission rod 4 and the body 1. When the transmission rod 4 slides, it has a first direction to push the trigger part 301 and a second direction to reset the trigger part 301. The first direction is opposite to the second direction. The elastic force of the elastic element 6 acting on the transmission rod 4 is in the same direction as the second direction. The elastic element 6 facilitates the reset of the transmission rod 4 and the trigger part 301, and is reliable in use. An annular flange 401 is provided on the transmission rod 4. The annular flange 401 is placed on the lower side of the first mounting groove 101 and abuts against the lower groove opening of the first mounting groove 101 for limiting. The elastic element 6 is a compression spring, which has a simple structure and low production cost. One end of the elastic element 6 abuts against the lower side of the annular flange 401, and the other end of the elastic element 6 abuts against the body 1, so the transmission rod 4 resets flexibly.
[0031] See Figure 3 , Figure 4 , Figure 9 and Figure 10The guide slope 5 includes a first guide slope 51 and a second guide slope 52. The upper part of the transmission rod 4 is provided with a third guide slope 41 corresponding to the first guide slope 51 and a fourth guide slope 42 corresponding to the second guide slope 52. A first positioning groove 53 for positioning the upper end of the transmission rod 4 is formed between the first guide slope 51 and the second guide slope 52. Under normal conditions and when the switch is off, the upper end of the transmission rod 4 falls into the first positioning groove 53. The turntable 2 is provided with a second positioning groove 21 for positioning the upper end of the transmission rod 4. The turntable 2 has a first rotation direction and a second rotation direction when rotating. When the turntable 2 rotates in the first rotation direction, the upper end of the transmission rod 4 slides relative to the first guide slope 51 and is guided into the second positioning groove 21 for positioning. At this time, the turntable is released. When the turntable switch is closed, the continuous operation mode is activated. Power is cut off by simply rotating the turntable in the second rotation direction to reset it, making operation convenient. When the turntable 2 rotates in the second rotation direction, the upper end of the transmission rod 4 slides relative to the second guide slope 52, maintaining the rotational position of the turntable 2. The trigger state of the trigger unit is manually maintained, thus activating the jog mode. In jog mode, power is cut off by simply releasing or resetting the turntable, making it easy to use. The upper end of the transmission rod 4 is provided with a first arc-shaped portion 43, and the turntable 2 is provided with a second arc-shaped portion 22 for guiding the first arc-shaped portion 43 into / out of the second positioning groove 21, facilitating the insertion or removal of the transmission rod 4 into or out of the second positioning groove 21 to enable or disable the continuous operation mode.
[0032] See Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 Switch 3 is a micro switch, and trigger part 301 is a trigger plate. Pressing the trigger plate activates switch 3, and the trigger plate has a certain elastic reset capability. A bearing 7 is provided between the machine body 1 and the turntable 2, which makes the turntable 2 rotate smoothly, with a simple structure and low production cost. The bearing 7 includes an inner rotating ring 71 and an outer rotating ring 72 that can rotate relative to each other. The inner rotating ring 71 is fixedly connected to the machine body 1, and the outer rotating ring 72 is fixedly connected to the turntable 2. The structure is simple and the production cost is low. In this embodiment, the bearing 7 is a ball bearing. Other suitable types of bearing 7 can also be selected as needed, which will not be elaborated here. Machine body 1 The upper part is provided with an annular mounting post 8. The inner side of the inner rotating ring 71 is fitted onto the outer side of the mounting post 8. The outer wall of the mounting post 8 is provided with a protrusion 81 for abutting and tightly fitting against the inner wall of the inner rotating ring 71. Multiple protrusions 81 are arranged in an annular pattern at equal intervals to ensure a stable assembly with the bearing 7. A fifth guide slope 811 is provided on the upper part of the protrusion 81. The inner side of the turntable 2 is provided with a rib 9 for abutting and tightly fitting against the outer wall of the outer rotating ring 72. A sixth guide slope 91 is provided on the upper part of the rib 9. The fifth guide slope 811 and the sixth guide slope 91 reduce the assembly difficulty of the bearing 7 assembly and reduce the assembly cost.
