Meat mincing knife assembly of meat mincing machine and meat mincing machine

Abstract

The meat mincer comprises a main machine and a meat mincing cup, the meat mincing knife assembly comprises a knife rest, a transmission shaft and a smashing knife arranged on the knife rest, the knife rest is provided with a containing cavity in the axial direction, at least part of the transmission shaft is arranged in the containing cavity, and the smashing knife is arranged in the containing cavity. An elastic piece is further arranged in the containing cavity, and the meat mincing knife assembly has a first state that the transmission shaft is exposed out of the containing cavity and a second state that the containing cavity tends to wrap the transmission shaft; in the first state, the meat mincing knife assembly is matched with the main machine and the meat mincing cup in place so that the main machine can be in transmission connection with the meat mincing knife assembly, and in the second state, the main machine cannot be in transmission connection with the meat mincing knife assembly. The second state of the meat mincing knife assembly comprises that the meat mincing knife assembly is matched with the main machine when being taken out of the meat mincing cup, and according to the scheme, when the meat mincing knife assembly is abnormally matched with the main machine and the meat mincing cup, the meat mincing knife assembly cannot rotate, and danger to a user can be avoided.

Description

technical field [0001] The invention relates to the technical field of small household appliances, in particular to a meat cutter assembly of a meat grinder and a meat grinder. Background technology [0002] When the trigger mechanism of the meat grinder is pressed in place, the trigger mechanism can be installed on the bottom of the meat grinder to protect the safety of the meat grinder. [0003] However, when using the meat grinder, if the user misoperates when the meat grinder cup is not installed, and the trigger button on the cup cover and the protection switch on the host are triggered at the same time, the whole machine is turned on, resulting in the sudden rotation of the meat grinder assembly. Because the meat grinder cup is not installed, the rotation of the meat grinder assembly has the hidden danger of injury, such as Figure 1 and Figure 2 As shown in, when the user reversely installs the whole machine, that is, when the main machine is placed upside down, the key swi...

AI Technical Summary

Problems solved by technology

[0003] However, when the user uses the meat grinder, if he misuses the meat grinder without installing the meat grinder cup, and triggers the trigger button on the cup cover and the protection switch on the host at the same time, the whole machine will turn on and cause the meat grinder assembly to rotate suddenly. If the meat grinder cup is not installed, the rotation of the meat grinder assembly may cause injury, such as figure 1 and figure 2 As shown, when the user reverses the whole machine, that is, when the host is placed upside down, due to the gravity of the host, the key switch on the top of the host will be triggered. Press the cup cover, under the action of the pressure and the gravity of the cup cover itself, the trigger rib on the cup cover triggers the protection switch, and the circuit of the meat grinder has been connected, so the whole machine is started at this time, and the meat grinder motor drives the meat grinder assembly. Sudden rotation, there is a risk of injury

[0004] The industry mainly informs users of the correct assembly sequence and assembly plan of the meat grinder by pasting warning signs on the side wall of the main machine, but this plan only serves as a reminder and cannot fundamentally solve potential safety hazards
