Detailed Description

The technical scheme of the utility model is further described and illustrated by specific embodiments below, so that the utility model is clearer and more obvious. Other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The utility model is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

As shown in fig. 1, fig. 2, fig. 3a, and fig. 3b, this embodiment relates to a safe food cooking apparatus, which includes a machine head 1, a machine head 2, and a machine body 3, which are sequentially arranged from top to bottom, wherein a motor 8 connected to the machine head 2 is disposed in the machine head 1, a ball switch 9 and a controller are further disposed in the machine head 1, the ball switch 9 is axially parallel to the motor 8, a switch pin 91 of the ball switch 9 of this embodiment faces downward, and the controller is respectively connected to the ball switch and the motor 8; when the handpiece 1 is inclined at a preset angle in an inverted or forward and forward direction, the controller prohibits the motor from starting. This embodiment installs parts such as motor, controller in the aircraft nose, seals up organism and aircraft nose through sealed lid, and the organism is as placing the container in kind, smashes food through stretching into each blade on the tool bit in the organism. The handpiece 1 is also provided with a usb interface for connecting an external power supply with the motor.

A ball switch 9 is arranged at a proper position parallel to the axial direction of the motor 8, and a switch pin 10 of the ball switch 9 faces downwards and is arranged at one end of the motor connected with a cutter head. The ball switch that this embodiment adopted is an electronic components, also known as vibrations switch, and its theory of operation does: when the switch is placed horizontally, the ball inside is in the middle position, the two contacts of the pin are disconnected, and when the direction of the pin of the switch inclines downwards for a certain angle, the ball rolls onto the pin, and the two contacts of the pin are communicated. The ball switch pin 91 may also be positioned facing upward (i.e., the ball switch is positioned above the pin).

Specifically, the device further comprises a starting switch 6, and the controller, the starting switch 6 and the motor are connected in sequence.

As shown in fig. 5, the controller of this embodiment includes an MCU chip, a resistor R1 and a resistor R2, and as shown in the figure, the ball switch is connected between the resistors R1 and R2, for example: when the head is placed in the reverse direction or inclined at a certain angle (more than 75 degrees) in the forward direction, the ball switches of fig. 6c (reverse) and 6d (75 degrees) are turned off, and the MCU judges that the low level is reached, the motor is not allowed to be started, and when the head is placed in the forward direction or inclined at less than 15 degrees, the ball switches of fig. 6a (forward) and 6b (inclined at 15 degrees) are turned on, and the MCU judges that the high level is reached, the motor is allowed to be started. The working logic is as shown in fig. 4, the ball switch is judged first, the start switch is judged, the limit switch is judged finally, and the motor is started only when all conditions are met. When a user inverts the machine head and installs the sealing cover and the motor, the ball switch timely judges the relative position of the machine head, and the motor is prohibited to be started no matter whether the starting switch and the limit switch are opened, so that the problem that the user is accidentally injured is effectively avoided. When the inclination of the inverted machine head is larger than a certain angle, the cutter head cannot be stably installed on the machine head, and the accidental injury situation is effectively avoided.
