Description

Technical Field

[0001] This utility model relates to the technical field of catering, and in particular to a meat grinder with a switch structure. Background Technology

[0002] A meat grinder is a kitchen appliance whose main function is to mince or cut meat, vegetables, and other ingredients into small pieces. It has wide applications in the catering industry and kitchens. A typical meat grinder includes a cup body, a lid, a blade assembly, a motor bracket, a motor, a housing, a microswitch, and a button. The lid is mounted on the top of the cup body, and the blade assembly is rotatably mounted on the lid, with its lower part inside the cup body. The motor bracket is mounted on the top of the lid, and the motor is mounted on the motor bracket. The motor's output is connected to the blade assembly. The microswitch is mounted outside the housing, and the button is also mounted outside the microswitch. A wiring harness is installed on the microswitch. In use, the wiring harness from the microswitch is first passed through a hole in the housing and then electrically connected to the motor. The meat to be minced is then placed into the cup body. After attaching the lid to the top of the cup body, attach the outer casing to the motor bracket, and then press the button to drive the motor to rotate the blade assembly, which in turn breaks up the meat inside the cup. However, there are some problems during use. Since the motor and micro switch are installed on two different parts, the outer casing and the motor bracket, respectively, when the outer casing is attached to the motor bracket, the wiring harness inside the outer casing cannot be properly organized, posing a risk of squeezing the wiring harness. If the wiring harness is squeezed for a long time, the insulation layer of the wiring harness may be broken, posing a risk of leakage. This makes it inconvenient to use and has poor safety. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a meat grinder with a switch structure that pre-fixes and straightens the wire harness on the motor bracket, so that when the outer shell is fastened to the motor bracket, it will not squeeze the wire harness, thus ensuring the safety of the wire harness during use. It is easy to use, reliable and practical.

[0004] This utility model discloses a meat grinder with a switch structure, comprising a button, a housing, a micro switch, a motor bracket, a cup lid, a cup body, and a blade assembly. The button is mounted on the upper part of the housing. The motor is fixedly mounted on the motor bracket, and the output end of the motor is connected to the upper end of the blade assembly. The blade assembly is rotatably mounted on the cup lid, and the motor bracket is fixedly mounted on the cup lid. The lower part of the blade assembly is located in the cup body, and the cup lid is mounted on the upper end of the cup body. The device also includes a mounting mechanism, a fixing mechanism, and a transmission mechanism. The micro switch is fixedly mounted on the motor bracket via the mounting mechanism. A wiring harness is provided on the micro switch and electrically connected to the motor. The fixing mechanism is mounted on the motor bracket and is used to fix the wiring harness. The transmission mechanism is mounted on the housing, and the lower end of the button is connected to the transmission mechanism. The contact and transmission mechanism transmits the movement of the button. In use, the operator first places the meat into the cup, then places the lid on top of the cup, and then attaches the outer casing to the motor bracket. Pressing the button then activates the microswitch via the transmission mechanism, which in turn connects the wiring harness, causing the motor to drive the blade assembly to rotate. During rotation, the blade assembly breaks up the meat in the cup. Because the wiring harness on the microswitch is pre-fixed to the motor bracket by a securing mechanism, and the harness is pre-aligned and secured, attaching the outer casing to the motor bracket will not affect or compress the wiring harness, ensuring its safety during use. The device is convenient to use, highly reliable, and practical.

[0005] Preferably, the fixing mechanism includes a buckle, and the motor bracket is provided with a wire groove, in which the wire harness is located. The wire harness is fixedly installed in the wire groove by the buckle, and there is at least one wire groove. With the above configuration, it is convenient to fix the wire harness in advance, and avoids squeezing the wire harness when the outer shell is fastened to the motor bracket. At the same time, cable ties can also be used to fix the wire harness in the wire groove.

[0006] Preferably, the mounting mechanism includes a micro switch bracket, which is fixedly mounted on the motor bracket by screws A, with at least one screw A. The micro switch bracket is provided with a micro switch clip, and the micro switch is fixedly mounted on the micro switch bracket by the micro switch clip. This arrangement facilitates the fixing of the micro switch. The micro switch is a normally open contact micro switch, or a lever-type normally open micro switch.

[0007] Preferably, the transmission mechanism includes a spring, a lever, a lever-spring limiting rib, and a mounting block. The upper end of the lever contacts the lower end of the button. The mounting block is fixedly mounted on the upper part of the housing. The upper part of the lever has a lever-spring limiting rib. The middle part of the mounting block has a spring mounting groove. The lower end of the spring mounting groove has a spring support surface. The lower part of the mounting block has a lever guide A that communicates with the spring mounting groove. The lever guide A guides the lever. The lever slides up and down on the lever guide A. The upper part of the micro switch has a contact. The lower end of the lever is located above the upper contact of the micro switch. The upper end of the spring is fixedly connected to the lower end of the lever-spring limiting rib. The lower end of the spring is fixedly connected to the spring support surface. The spring is in a compressed state. The dimensions of the spring mounting groove and the spring support surface are both larger than the outer diameter of the spring. The gap between the lever and the lever guide A is 0.1-5 μm. The lever guide A limits the lever's position, ensuring accurate contact with the microswitch contacts during descent. The spring mounting slot facilitates positioning of the upper part of spring 2, preventing it from detaching from the lever. The spring support surface facilitates positioning of the lower part of spring 2, preventing it from losing support. When the microswitch is pressed, the outer casing is first fastened to the upper end of the motor bracket. Pressing the button causes the lever to descend, bringing its lower end into contact with the upper contacts of the microswitch. This activates the wiring harness on the microswitch, starting the motor connected to it. When the button is stopped, the spring's elasticity causes the lever spring limit rib to rise, disengaging the lever from the microswitch and restoring the wiring harness to its open circuit state, stopping the motor. This improves convenience.

[0008] Preferably, it also includes screw B, and the motor is fixedly mounted on the motor bracket by screw B, and there are at least two screws B; the above arrangement facilitates the positioning of screw B.

[0009] Preferably, the upper part of the micro switch bracket is provided with a lever guide part B, the lower part of the lever is located inside the lever guide part B, and the contact of the micro switch is located inside the lever guide part B; through the limiting effect of the lever guide part B on the lower part of the lever, the lever can accurately contact the contact of the micro switch during the descent process, preventing lever misalignment and ensuring reliability.

[0010] Preferably, it also includes a positioning shaft, which is rotatably installed in the lower part of the cup body and works in conjunction with the lower part of the knife holder assembly; the lower part of the knife holder assembly is provided with a positioning hole, and the positioning shaft is inserted into the positioning hole in the lower part of the knife holder assembly; when the cup lid is fastened on the cup body, the positioning shaft is inserted into the positioning hole in the lower part of the knife holder assembly, which facilitates the positioning of the knife holder assembly in the cup body and improves reliability.

[0011] Preferably, the lower part of the button is provided with a button buckle, and the outer shell is provided with a button buckle positioning surface. The button is fixedly engaged with the button buckle positioning surface by the button buckle. The above configuration facilitates the installation between the button and the outer shell.

[0012] Preferably, the cross-sectional shape of the lever is any one of a circle, a square, and an ellipse.

[0013] Compared with the prior art, the advantages of this utility model are: the wire harness is fixed and straightened on the motor bracket in advance, and when the outer shell is fastened on the motor bracket, it will not cause compression to the wire harness, thus ensuring the safety of the wire harness during use. It is convenient to use and has high reliability and practicality. Attached Figure Description

After pressing button 1, button 1 presses the micro switch 5 through the transmission mechanism, thereby energizing the wiring harness and causing the motor 9 to drive the blade assembly 13 to rotate. During rotation, the blade assembly 13 breaks up the meat in the cup body 12. Since the wiring harness on the micro switch 5 is pre-fixed to the motor bracket 8 by a fixing mechanism, and the wiring harness is pre-organized and fixed, when the outer casing 3 is fastened to the motor bracket 8, it will not affect or compress the wiring harness on the micro switch 5, ensuring the safety of the wiring harness during use. This design is convenient, reliable, and practical.

[0020] like Figure 1 The fixing mechanism includes a buckle. The motor bracket 8 is provided with a wire groove 8-1, and the wire harness is located in the wire groove 8-1. The wire harness is fixedly installed in the wire groove 8-1 by the buckle. There is at least one wire groove 8-1. The above setting facilitates the pre-fixing of the wire harness and avoids squeezing the wire harness when the outer shell 3 is fastened to the motor bracket 8.
