[0034] In the related art, the mixer is often used for mixing, mixing, whipping cream or egg liquid in food processing, in order to prevent foreign matter from falling into the stirring barrel during stirring, or to prevent the hand from touching the executing mechanism being stirred, the mixer on the market is often provided with a protective net and a safety switch. When the protective net is opened during stirring, the protective net will trigger the safety switch, and the mixer will automatically stop, avoiding accidental injury. The mixer currently on the market is equipped with a safety switch when leaving the factory, however, for some customers who do not need to install the protective net, the safety switch is also not needed, therefore, a machine body without safety switch needs to be designed additionally, thereby causing the increase of design, production and storage costs.

[0035] To solve the above problems, refer to Figure 1 and Figure 3 In the embodiment of the first aspect of the utility model, an optional safety switch is provided, which comprises a mounting seat 101, a sensor 110 and a transmission rod 113, the sensor 110 is fixed on the mounting seat 101, the sensor 110 has a movable paddle 111, the transmission rod 113 is detachably installed on the mounting seat 101 and located on one side of the sensor 110, the transmission rod 113 has a first wall surface 115, when the transmission rod 113 moves along its axis direction, the first wall surface 115 can abut and push the end of the paddle 111, so that the paddle 111 moves, thereby triggering the sensor 110, the sensor 110 sends a signal to the control system of the mixer to pause stirring, realizing the function of safety protection.

[0036] Specifically, the axis direction of the transmission rod 113 is parallel to the vertical direction, and the transmission rod 113 moves in the vertical direction within the mounting base 101. The mounting base 101 comprises a first mounting portion 103 connected to the mixer and a second mounting portion 104 to which the sensor 110 is fixedly mounted. Further, the second mounting portion 104 is provided with a guide portion 118 having a plug hole 119 in which the transmission rod 113 is plugged, and the plug hole 119 can guide the movement of the transmission rod 113 in the vertical direction, which is conducive to improving the movement stability of the transmission rod 113. In this embodiment, the guide portion 118 is provided with at least two, and each of the two guide portions 118 has a plug hole 119 in which the transmission rod 113 is plugged, which can improve the movement stability of the transmission rod 113.

[0037] It can be understood that one end of the dial piece 111 is pivotally connected to the sensor 110, the first wall surface 115 can abut against the other end of the dial piece 111 away from the pivot part, and the transmission rod 113 is located on the side of the dial piece 111 away from the sensor 110. It can be understood that the end of the dial piece 111 has a pivotally connected roller 112, and the first wall surface 115 can abut against the radial outer wall of the roller 112 when the transmission rod 113 moves along its axis direction.

[0038] Referring to Figure 2 It can be understood that the transmission rod 113 further comprises a second wall surface 116 and a third wall surface 117, the second wall surface 116 is arranged opposite to the first wall surface 115, and the third wall surface 117 is located between the first wall surface 115 and the second wall surface 116, and the first wall surface 115, the second wall surface 116 and the third wall surface 117 jointly define a containing groove 120. Further, the containing groove 120 is recessed and surrounds the outer peripheral wall of the transmission rod 113, so that the transmission rod 113 does not need to be adjusted in direction when being installed, which is conducive to the convenient installation of the transmission rod 113. Further, the first wall surface 115 and the second wall surface 116 are conical surfaces, and along the axial direction of the transmission rod 113, the distance between the end of the first wall surface 115 away from the third wall surface 117 and the end of the second wall surface 116 away from the third wall surface 117 is greater than the extension length of the third wall surface 117 along the axis direction of the transmission rod 113, which is conducive to reducing the resistance of the transmission rod 113 driving the dial piece 111 and improving the triggering efficiency of the sensor 110.

[0039] It can be understood that the dial 111 is elastically pivotally connected to the sensor 110, so that the roller 112 can elastically press against the outer circumferential wall of the transmission rod 113. Therefore, when the roller 112 is located in the accommodating groove 120, the roller 112 can elastically press against the third wall surface 117. At the same time, due to the action of gravity, the transmission rod 113 has a falling movement tendency, so that the roller 112 can elastically press against the second wall surface 116, so that the transmission rod 113 is stably installed in the mounting seat 101. It can be understood that, when the sensor 110 is not triggered, the roller 112 is embedded in the accommodating groove 120 and can press against the third wall surface 117 and the second wall surface 116; when triggered, the transmission rod 113 is pushed and moves upward, the first wall surface 115 presses against the roller 112, and the dial 111 is rotated, the end of the dial 111 provided with the roller 112 moves away from the transmission rod 113 in the radial direction of the transmission rod 113, so as to trigger the sensor 110. When the transmission rod 113 is disassembled, the second wall surface 116 presses against the roller 112 and moves the end of the dial 111 provided with the roller 112 towards the sensor 110, so that the transmission rod 113 is separated from the mounting seat 101, which is beneficial to facilitate disassembly and improve operation efficiency.

[0040] According to the embodiment of the second aspect of the utility model, a blender is provided, which comprises the optional safety switch. Referring to Figure 4 It can be understood that the blender comprises a box body 100, the mounting seat 101 is fixedly installed in the box body 100, the transmission rod 113 has a triggering end 114, the triggering end 114 extends out of the box body 100, the outer wall of the box body 100 is provided with a detachable sliding sleeve 102, and the transmission rod 113 is movably arranged in the sliding sleeve 102.

[0041] It can be understood that the box body 100 is provided with a threaded hole, the sliding sleeve 102 is detachably installed on the box body 100 in a threaded connection mode with the threaded hole, and the sliding sleeve 102 extends downward from the outer wall of the box body 100 along the axis direction of the transmission rod 113. On the one hand, the sliding sleeve 102 has a guiding effect on the transmission rod 113, and the movement stability of the transmission rod 113 can be improved. On the other hand, on the blender without the safety switch function, by disassembling the sliding sleeve 102 and the transmission rod 113 and screwing a bolt in the threaded hole, the configuration can be changed, the body design of the blender does not need to be changed, the design and production costs can be effectively reduced, and the configuration flexibility of the product can be improved.

[0042] The embodiments of the utility model are described in detail above combined with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by ordinary skilled in the art without departing from the purpose of the utility model.
