Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processors, and in particular to food processors with an emergency stop function when the lid is opened. Background Technology
[0002] A stand mixer is a multi-functional household food processing device. Currently, stand mixers on the market generally have functions such as kneading dough, mixing, whipping egg whites, mincing meat, and pressing dough. Due to its rich functions, it can help users make a variety of foods, and therefore it is loved by people.
[0003] Currently, existing smart food processors typically have the blending cup placed directly on or fixed to the machine body during use. Furthermore, when the food processor is in operation with the blending cup, it is easy for the machine to continue running even after the cup lid is opened, which can pose a safety hazard to the user. Therefore, a food processor with an emergency stop function when the lid is opened has been proposed. Utility Model Content
[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.
[0005] A food processor with an emergency stop function upon opening the lid includes a food processor body. A blending cup is vertically inserted into one side of the top of the food processor body, and a micro switch is provided between the blending cup and the food processor body. The micro switch is vertically located inside the top of the food processor body. A handle is vertically located on one side of the outside of the blending cup, and a handle shell is provided to cover the handle. A locking lever is obliquely movable at the top of the handle shell, and a cavity is formed at the connection between the handle shell and the handle. A connecting rod is vertically arranged inside the cavity, and a connecting platform is horizontally arranged at the bottom of the cavity. A lifting rod is vertically and elastically movable on one side of the connecting platform, and a first connecting member is horizontally arranged at the top of the lifting rod. A micro-motion rod is vertically arranged at the bottom of the first connecting member, and the micro-motion rod is parallel to the micro switch. One end of the connecting rod is movably connected to a second connecting member, and the second connecting member abuts against the locking lever. The other end of the connecting rod is movably connected to the first connecting member.
[0006] Preferably, a second spring is provided between the connecting platform and the lifting rod, and the second spring is vertically arranged on the connecting platform. The lifting rod is vertically inserted into the second spring, and the top end of the lifting rod is elastically connected to one end of the second spring, and the other end of the second spring is elastically connected to the connecting platform.
[0007] Preferably, a first spring is provided between the locking lever and the handle housing, and one end of the first spring is elastically connected to the handle housing, and the other end of the first spring is elastically connected to the locking lever.
[0008] Preferably, the blending cup is provided with a lid, which covers the top of the blending cup, and one side of the bottom end of the lid abuts against the locking lever.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When the blending cup is placed vertically on the main body of the food processor, the micro-motion rod and the micro-switch abut against each other, and the micro-switch controls the main body of the food processor to drive the blending cup. When the user presses the locking lever and releases the abutment between the second connecting piece and the cup lid, the lifting rod elastically resets and drives the second connecting piece upward. When the second connecting piece is pushed upward, the connecting rod moves upward inside the cavity, and when the connecting rod moves upward, it pulls the second connecting piece, thereby driving the second connecting rod and the micro-motion rod upward and separating the micro-motion rod from the micro-switch. This causes the micro-switch to shut down the main body of the food processor and disconnect the drive between the main body of the food processor and the blending cup, thus ensuring the safety of the main body of the food processor.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-5In this embodiment of the invention, a food processor with an emergency stop function upon opening the lid includes a food processor body 1. A blending cup 2 is vertically inserted into one side of the top of the food processor body 1, and a micro switch 10 is provided between the blending cup 2 and the food processor body 1. The micro switch 10 is vertically located inside the top of the food processor body 1. A handle 12 is vertically provided on one side of the outside of the blending cup 2, and a handle shell 13 is provided to cover the handle 12. A locking lever 4 is obliquely movable at the top of the handle shell 13, and a locking lever 4 is provided between the handle shell 13 and the handle 12. A cavity (not shown in the figure) is formed at the connection point. A connecting rod 5 is vertically arranged inside the cavity, and a connecting platform 14 is horizontally arranged at the bottom of the cavity. The connecting platform 14 is horizontally fixed to the side of the handle housing 13. A lifting rod 16 is vertically and elastically movable on one side of the connecting platform 14, and a first connecting member 8 is horizontally arranged at the top of the lifting rod 16. The lifting rod 16 and the first connecting member 8 move in the same direction. A micro-motion rod 9 is vertically arranged at the bottom of the first connecting member 8, and the micro-motion rod 9 is parallel to the micro switch 10. The lifting rod 16 can drive the first connecting piece 8 to move up and down on the connecting platform 14. One end of the connecting rod 5 is movably connected to the second connecting piece 11, and the second connecting piece 11 abuts against the locking lever 4. The other end of the connecting rod 5 is movably connected to the first connecting piece 8. Thus, when the blending cup 2 is placed vertically on the main body 1 of the food processor, the micro-motion rod 9 abuts against the micro switch 10, and the micro switch 10 controls the main body 1 of the food processor to drive the blending cup 2. When the user presses the locking lever 4 and releases the second connecting piece 11 and the cup lid 3, the user can move the first connecting piece 8 up and down on the second connecting piece 11 and the cup lid 3. The contact causes the lifting rod 16 to elastically reset and drive the second connecting member 11 to push upward. When the second connecting member 11 pushes upward, it causes the connecting rod 5 to move upward inside the cavity. When the connecting rod 5 moves upward, it pulls the second connecting member 11, thereby driving the second connecting rod 11 and the micro-motion rod 9 to move upward and causing the micro-motion rod 9 to separate from the micro switch 10. This causes the micro switch 10 to shut down the main body 1 of the food processor and disconnect the drive between the main body 1 of the food processor and the blending cup 2, thus ensuring the safety of the main body 1 of the food processor.
[0020] A second spring 15 is provided between the connecting platform 14 and the lifting rod 16, and the second spring 15 is vertically arranged on the connecting platform 14. The lifting rod 16 is vertically inserted into the second spring 15, and the top end of the lifting rod 16 is elastically connected to one end of the second spring 15, and the other end of the second spring 15 is elastically connected to the connecting platform 14. Thus, when the lifting rod 16 and the first connecting member 8 are raised and lowered on the connecting platform 14, the second spring 15 can perform elastic buffering movement and drive the connecting rod 5 to drive the second connecting member 11 to move.
[0021] A first spring 6 is provided between the locking lever 4 and the handle housing 13. One end of the first spring 6 is elastically connected to the handle housing 13, and the other end of the first spring 6 is elastically connected to the locking lever 4. Thus, the locking lever 4 is elastically oscillating at the top of the handle housing 13 through the first spring 6, thereby abutting against the second connecting member 11 and the cup lid 3, thereby limiting and fixing the second connecting member 11 and the cup lid 3.
[0022] The blending cup 2 is provided with a cup lid 3, which covers the top of the blending cup 2, and one side of the bottom end of the cup lid 3 abuts against the locking lever 4.
[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
