The term "and / or" as used herein includes any combination of one or more of the associated listed items.

[0026] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various elements, these elements should not be limited to these terms. These terms are only used to distinguish elements of the same type from one another. For example, without departing from the scope of this disclosure, a first element may also be referred to as a second element, and similarly, a second element may also be referred to as a first element.

[0027] Reference Figures 1 to 4 As shown, in some embodiments, this utility model discloses a safety switch structure for a food mixer, comprising: Reference Figures 1 to 3 The mixer base 100 shown includes a drive motor 110 and a motor bracket 120 connected to the top of the drive motor 110, and a first mounting frame 121 integrally formed with the motor bracket 120. The motor bracket is used to support and fix the entire safety switch structure.

[0028] Continue to refer to Figures 1 to 3 As shown, a safety switch structure 200 is disposed inside the first mounting frame 121. The safety switch structure 200 includes a second mounting frame 210, a micro switch 220 disposed on the second mounting frame 210, a first trigger rod 230, and a first elastic element 240.

[0029] Reference Figure 1 Combination Figure 2As shown, the micro switch 220 includes a switch body 221, a resilient button 223 disposed on one side of the switch body 221, and a power-on terminal 222 disposed on the other side of the switch body 221. The structure of the micro switch is usually a standard component that can be purchased commercially. The power supply port of the drive motor 110 is electrically connected to the power-on terminal 222. The electrical connection can be made directly using electrical wiring. When the resilient button is pressed, the motor is powered by the mains electricity, and the mixer can then perform the mixing operation.

[0030] Continue to refer to Figure 2 As shown, the second mounting frame 210 includes a sliding channel 211. The first trigger rod 230 is connected to the first elastic element 240 and disposed within the sliding channel 211. The first trigger rod 230 is disposed adjacent to the micro switch 220. When an external component of the mixer presses down on the top of the first trigger rod 230, the first trigger rod 230 overcomes the elastic force of the first elastic element 240 and presses the elastic button 223, allowing the energized end 222 to be energized. The triggering method of this safety switch is simple and direct; switching between energization and de-energization can be achieved by pressing down on an external component. The operation is convenient and quick, improving the user experience. By placing the safety switch structure inside the first mounting frame, and with the first mounting frame and motor bracket integrally formed, an integrated design of the drive motor bracket and the energized safety switch is achieved. This simplifies the overall structure of the mixer, reduces the number of parts, lowers manufacturing costs and assembly difficulty, and improves product reliability and stability. Furthermore, when the safety switch structure is assembled with the drive motor bracket, the vibration generated by the drive motor is synchronized with the safety switch structure. Similarly, when the mixer, such as the mixing cup, is assembled and connected to the mixer base, it is synchronized with the vibration of the drive motor. This ensures that the components of the mixing cup trigger the first trigger rod to perform energization, making the microswitch's energization state more stable.

[0031] Continue to refer to Figure 2 As shown, the bottom end of the first trigger rod 230 is provided with a limiting part 231, which is correspondingly set to the bottom edge of the sliding channel 211. The limiting part at the bottom end of the first trigger rod 230 is correspondingly set to the bottom edge of the sliding channel, which can effectively prevent the first trigger rod from falling off during the sliding process, ensure its stable movement in the sliding channel, and improve the reliability and durability of the safety switch structure.

[0032] Reference Figure 2 Combination Figure 3As shown, the mixer base 100 includes a top shell 130 positioned above the motor bracket 120. The top shell 130 has a mounting opening, and the top of the micro switch 220 is movable along the mounting opening. The top shell and the movable design of the micro switch top on the mounting opening provide a stable mounting position and movement space for the micro switch, making the assembly between components more precise, further enhancing the stability of the entire safety switch structure, and reducing the risk of failure due to assembly errors.

[0033] Reference Figure 1 As shown, the switch body 221 has more than one positioning through hole, and the second mounting frame 210 is provided with a positioning rod 212 corresponding to the positioning through hole and a locking block 213 that engages with both ends of the switch body 221. The multiple positioning through holes on the switch body cooperate with the positioning rod and locking block on the second mounting frame to stably fix the micro switch on the second mounting frame, preventing it from shifting or loosening during operation, ensuring the normal operation of the micro switch, and improving the stability and reliability of the safety switch structure.

[0034] Continue to refer to Figure 1 As shown, the two ends of the second mounting frame 210 are fixedly connected to the first mounting frame 121 by bolts. The connection between the second mounting frame and the first mounting frame by bolts is firm and reliable, and can withstand a certain amount of external impact, which enhances the structural strength of the entire safety switch structure, enabling it to remain stable during the operation of the mixer and extending the service life of the product.

[0035] Reference Figure 2 As shown, the first elastic element 240 is a spring. The spring's compact and reasonable arrangement does not occupy too much space, making the entire safety switch structure more compact. This is beneficial for the overall miniaturization and lightweight design of the mixer, while also reducing manufacturing costs. The spring is sleeved on the first trigger rod 230, and both ends of the spring abut against the internal limiting points of the second mounting frame 210 and the limiting points on the first trigger rod 230, respectively. This provides stable elastic support for the first trigger rod, allowing it to overcome the elastic force and press the elastic button smoothly when subjected to external pressure. Simultaneously, it can quickly return to its original position after the external pressure is released, ensuring the sensitivity and response speed of the safety switch and improving the safety and ease of operation of the mixer.

[0036] Reference Figure 3As shown, the mixer base 100 includes a lower frame 140 covering the lower part of the drive motor 110. The motor bracket 120 is circumferentially bolted and fixedly connected to the lower frame 140. The motor bracket, fixedly connected to the lower frame by the circumferential bolts, provides stable support and protection for the drive motor, preventing it from shaking or shifting during operation. This improves the overall structural stability and smooth operation of the mixer, reduces noise and vibration, and enhances the user experience.

[0037] Reference Figure 4 As shown, the bottom circumferential of the top shell 130 is provided with multiple positioning posts 131, and the first mounting frame 121 is provided with positioning notches 1210 that match the shape of the positioning posts 131. The positioning posts at the bottom of the top shell match the positioning notches on the first mounting frame. This design enables quick and accurate positioning and assembly between the top shell and the first mounting frame, reduces alignment errors during assembly, improves assembly efficiency and quality, ensures tight fit between components, and enhances the structural stability of the entire mixer base. In addition, the positioning posts and positioning notches make the connection between the top shell and the first mounting frame tighter, reduce gaps between components, and make the structure of the mixer base more compact, which is conducive to the overall miniaturization design of the mixer, and also improves the appearance quality and aesthetics of the product.

[0038] Reference Figures 5 to 7 As shown, in some embodiments, this utility model discloses a mixer including the aforementioned mixer safety switch structure. A mixing cup assembly is detachably connected to the mixer base 100. Specifically, the top shell 130 is circumferentially provided with multiple latches 133, and the first trigger rod 230 is disposed between a pair of adjacent latches 133. A buckle 311 is provided on the mixing cup 310 above each latch. The latches circumferentially provided on the top shell and the buckle structure on the mixing cup can stably fix the mixing cup to the top shell, preventing the mixing cup from shaking or loosening during mixer operation, ensuring a tight fit between the mixing cup and the mixer base, improving the overall structural stability and smooth operation of the mixer, reducing noise and vibration, and enhancing the user experience.

[0039] Continue to refer to Figures 5 to 7 As shown, the mixing cup assembly includes a mixing cup body 310 and a handle portion 320 fixedly connected to the mixing cup body 310. The handle portion 320 has a second trigger rod 330 that can move up and down, and a second elastic element 340 connected to the second trigger rod 330. An opening is provided at the top of the mixing cup body 310. (Refer to...) Figure 5As shown, the cover 400, detachably connected to the opening, when closed, presses down on the top of the second trigger rod 330 against the elastic force of the second elastic member 340, and the bottom of the second trigger rod 330 presses down on the top of the first trigger rod 230. By integrating the blender safety switch structure with the blending cup assembly, the second trigger rod is only pressed down when the cover is correctly closed on the opening of the blending cup, thereby triggering the first trigger rod, energizing the safety switch, and allowing the blender to start. This design improves the overall safety of the blender, ensuring that users will not come into contact with the high-speed rotating blades due to improper installation of the blending cup or an open cover, effectively preventing accidents.

[0040] Continue to refer to Figures 5 to 7 As shown, the second trigger rod 330 has a protrusion 331 at its bottom. One end of the second elastic member 340 is sleeved on the protrusion 331. The cooperation between the protrusion at the bottom of the second trigger rod and the second elastic member, as well as the limiting component near the top shell mounting opening and the ramp on the first trigger rod, make the triggering action between the second trigger rod and the first trigger rod smoother and more reliable. The other end of the second elastic member 340 abuts against the inner wall of the handle portion 320, and the bottom end of the second trigger rod 330 extends from the through hole at the bottom of the handle portion 320. By pressing the top end of the first trigger rod with its bottom end, it ensures that the safety switch can be triggered in a timely and accurate manner, improving the safety and reliability of the mixer.

[0041] The top shell 130 has a limiting component 132 near the mounting port. One side of the limiting component 132 has a notch corresponding to the bottom end of the second elastic member 340. The first trigger rod 230 has a ramp 232 at one end corresponding to the notch. The limiting component limits the bottom end of the second elastic member, preventing displacement or loosening during operation. Similarly, the ramp structure of the first trigger rod 230 helps guide the contact and triggering action between the second and first trigger rods, further enhancing the stability and reliability of the entire mixer structure and reducing the risk of malfunctions due to loose components or poor triggering.
