This application circumference indicates the circumferencial direction when bowl cover 42 is rotatory, when bowl cover 42 does not close soon when in place or bowl cover 42 is in the open mode, electric conductor 8 not with the contact of driving plate 91 to can not trigger safety switch 9, motor 3 is out of work, thereby has guaranteed safety, avoids bowl cover 42 not install in the user can stretch into cup 41, thereby by the risk of stirring sword 5 incised wound, realizes uncapping the outage. The advantages of such an arrangement are: the driving sheet and the metal sheet extend towards the cup body and are contacted and matched with the electric conductor 8, can realize that the safety signal and the anti-overflow signal can be communicated after the cup cover 42 is screwed in place, thereby ensuring that the high-speed wall-breaking food processor can work, the anti-overflow detection can be realized while the power failure during opening the cover is realized, the function that one conductor 8 can simultaneously communicate a safety signal and an anti-overflow signal is achieved, in addition, the electric conductor 8 is in circumferential contact with the driving sheet 91 and the metal sheet 10, so that the contact mode is simpler, the contact reliability is ensured, the circumferential contact only needs to consider the circumferential contact matching without considering the contact in the vertical direction, the structural requirement of the electric conductor 8 is reduced, the service life of each part is prolonged, the rotary operation of the user is ensured to be portable, and simultaneously, the use process is safer and more reliable. The distance between the electric conductor and the cup body is larger than the distance between the driving sheet and the distance between the metal sheet and the cup body, so that the electric conductor can be triggered to the driving sheet and the metal sheet in the rotating process, and the connection of signals is ensured.
In this embodiment, the safety switch 9 is a microswitch, the metal sheet 10 is a metal elastic sheet, the driving sheet 91 and the metal elastic sheet both have elasticity, and the safety switch 9 is located above the metal sheet 10.
The sheetmetal 10 is located the upstream side of driving plate 91, the place that the upstream that indicates in this application cup cover 42 rotation in-process priority reaches is the upstream, and the place that later reaches is the low reaches, the rotatory in-process of cup cover 42, electric conductor 8 contact sheetmetal 10 earlier and contact driving plate 91, close the back in place soon as cup cover 42, and electric conductor 8 and driving plate 91 and sheetmetal 10 all contact, realize that safety signal and anti-overflow signal switch on jointly. The advantages of such an arrangement are: the metal sheet 10 is positioned at the upstream side of the driving sheet 91, so that the electric conductor 8 is preferentially contacted with the metal sheet 10 in the rotating process, the anti-overflow signal is preferentially conducted, the safety signal is not conducted at the moment, and the anti-overflow signal is preferentially conducted over the safety signal; and when the bowl cover 42 closes soon after target in place, anti-overflow signal switches on with the safety signal jointly, makes safelyr like this, has avoided the emergence of following condition, 1: when high-speed broken wall cooking machine only set up the anti-overflow device and do not set up safety switch 9, then do not possess the function of the outage of uncapping, whether bowl cover 42 closes soon to target in place, the machine all works as usual, thereby there is the potential safety hazard, the human body stretches into the inside risk of cup 41 in the course of the work appears easily, for example when closing soon not to target in place in addition, when the anti-overflow signal does not switch on, the machine still normally works, because the anti-overflow signal does not switch on in the heating process, consequently, the thick liquid after the heating can flow, lead to damaging the host computer and take place the incident. 2: when high-speed broken wall cooking machine possesses safety switch 9 and anti-overflow device simultaneously, generally be safety signal and anti-overflow signal and switch on or break off simultaneously, for example metal connecting rod structure among the background art, work under the prerequisite that anti-overflow signal and safety signal all switched on in can guaranteeing the course of the work like this, but anti-overflow structure damages or contact failure time, or when the conducting rod rotation in-process triggered safety switch 9 but not contacted sheetmetal 10, the anti-overflow signal does not switch on, also can take place the condition that the thick liquid spills over. The anti-overflow signal is conducted in priority to the safety signal, so that the anti-overflow signal is communicated before the machine can normally work, the transmission of the anti-overflow signal is ensured in the working process of the machine, and the absolute safety is ensured. The situation that when the safety switch 9 is switched on, but the anti-overflow signal is not switched on, the anti-overflow is disabled is avoided. The anti-overflow signal conduction in the application refers to a state that the conductor 8 is in contact with the metal sheet 10 and can be electrified, and the safety signal conduction refers to a state that the conductor 8 triggers the safety switch 9 and the motor 3 can work.

The safety stroke range is 0.5 mm-5 mm, when the safety stroke is less than 0.5mm, the safety stroke is too short, the cup cover 42 needs to be completely screwed to the tail end to trigger the safety switch 9, so that the operation is troublesome, the relative rotation of the cup cover 42 due to slight vibration can cause the failure of the safety switch 9, the safety switch 9 cannot be conducted in the working process, and the power failure of the motor 3 is avoided, so that the machine cannot work; when the safety stroke is larger than 5mm, the safety stroke is too long, so that the cup cover 42 can start to work without being screwed in place, the heated liquid can overflow in the working process, and the potential safety hazard is increased. In the embodiment, the safety stroke is 2mm, so that the safety and the sealing effect of the cup cover 42 are ensured. The advantages of such an arrangement are: through the setting that the drive stroke is greater than safe stroke for when electric conductor 8 first contact sheetmetal 10 and driving plate 91 simultaneously, sheetmetal 10 is connected with electric conductor 8 and is switched on, and the anti-overflow signal switches on, but driving plate 91 only contacts with electric conductor 8, and driving plate 91 is not in safe stroke, and consequently safety switch 9 is not triggered, and the safety signal does not switch on. When the cup cover 42 continues to rotate, the driving plate 91 enters a safe stroke, and the safety signal is conducted at the moment, so that the machine works, the anti-overflow signal is ensured to be conducted prior to the safety signal, the absolute safety of the machine in the working process is ensured, and the anti-overflow signal is prevented from being out of order in the working process.
