Safety control method of juicer

Abstract

The invention relates to a safety control method of a juicer. The method comprises the following steps: 1, detaching a juicer main machine from a juicing cup; different from the prior art, the methodcomprises the following steps: after the juicer is standby for a period of time each time, enabling the juicer to enter a safety protection locking state; then, separating the juicer main machine fromthe juicing cup, and then re-assembly the juicer main machine and the juicing cup together, so the safety switch is enabled to switch the on-off state for one time; if the safety switch cannot perform state switching: if so, the control circuit board on the juicer judges that the safety switch fails or is damaged or fails, and the juicer will be automatically locked, and cannot be started. Therefore, according to the method, the event that a user or a child is cut by mistakenly pressing the starting switch and starting the juicer main machine under the conditions that the juicer main machineis not provided with the juicing cup and the safety switch is invalid and is in a closed state is effectively avoided, so the user or the child is prevented from being cut by a juicing knife of the juicer.

Description

technical field [0001] The invention relates to the technical field of fruit juice machines, in particular to a safety control method for fruit juice machines. Background technique [0002] In order to meet the requirements of safety regulations, the existing fruit juice machines generally require a safety switch and a start switch on the host of the juice machine. Only in the normally closed state, the safety switch gives a signal to the control circuit board, and when the user presses the start switch, the circuit board of the fruit juice machine controls the motor to drive the juicer knife to rotate and squeeze the juice. But the existing fruit juice machine has the following disadvantages: (1) the juice machine is used for a long time, and the safety switch is easily damaged or fails. Once the safety switch is damaged or fails, the safety switch will be in a normally closed state or a normally open state, which will cause Even if the main unit is not assembled with the ...

But the existing fruit juice machine has the following disadvantages: (1) the juice machine is used for a long time, and the safety switch is easily damaged or fails. Once the safety switch is damaged or fails, the safety switch will be in a normally closed state or a normally open state, which will cause Even if the main unit is not assembled with the juicer cup and the juicer knife is exposed, if an adult or child presses the start switch by mistake, the juicer knife on the main unit of the juicer will start to rotate, which is easy to cut the user and poses a safety hazard
