With reference to fig. 1 and fig. 2, the embodiment of the present application provides a food processor 100 (taking a small-sized meat grinder as an example), including casing 100, cup 102, motor 103, work unit 104 and controlling means 105, controlling means 105 includes circuit board 1, first switch module 2 and second switch module 3, circuit board 1, first switch module 2 reach motor 103 electric connection, the circuit board includes first metal contact 11a and second metal contact 11b (the specific description is given below), can to when second switch module 2 breaks off circuit board 103 signals, controlling means 105 controls motor 103 to provide power in order to drive work unit 104.

The circuit board 1 has a first through hole a, the second switch component 3 includes a connecting rod 32, a spring 31 and a conducting strip 33, the connecting rod 32 includes a limiting arm 321, the limiting arm 321 includes a connecting surface 321a facing the circuit board 1 and an opposite abutting surface 321b, the connecting rod 32 further includes a first end 32a and a second end 32b arranged along the length direction thereof, the limiting arm 321 is located between the first end 32a and the second end 32b, the circuit board includes a metal contact 11, the metal contact 11 includes a first metal contact 11a and a second metal contact 11b and is integrated on the circuit board 1, and the connecting rod 32 passes through the first through hole a of the circuit board 1.

With reference to fig. 3, a food processor 100 (taking a small-sized meat grinder as an example) is provided in the embodiment of the present application, the housing 100 accommodates the motor 103 and the implementation control device 105 in the housing 100, the first switch assembly 2 includes a trigger 21 and a first switch 22, the trigger 21 is fixedly connected to the housing 100, the first switch 22 is integrated on the circuit board 1, the trigger 21 abuts against the first switch 22, and pressure can be applied to the trigger 21 from the outside of the housing, so as to control the first switch 22 to be turned on or off.

The conductive sheet 33 is fixedly connected to the connecting surface 321a of the connecting rod 32, the conductive sheet 33 is disposed corresponding to the metal contact 11, the spring 31 is sleeved on the first end portion 32a, one end of the spring 31 abuts against the inner wall of the casing 100, and the other end abuts against the abutting surface 321b of the limiting arm 321. When the connecting rod 32 is forced to move along the length direction, the spring 31 is pressed to contract and deform. When the external force is removed, the spring is restored to the original state.

The housing 100 further has at least one groove 4 (two grooves in this embodiment), the groove 4 is formed outside the housing 100 and located at the bottom of the housing 100, the bottom of the groove 4 penetrates through to form a second through hole B, the second end portion 32B penetrates through the second through hole B, and the second end portion 32B protrudes out of the housing 100.

The cup body 102 has at least one protrusion 5 (two protrusions in this embodiment), the protrusion 5 is disposed corresponding to the groove 4, and the height of the protrusion is less than or equal to the depth of the groove. The second end 32b passes through the groove and the second through hole and abuts against the bump. Preferably, the length of the second end portion 32B extending out of the second through hole B is less than the depth of the groove 4 and less than the distance from the first end portion 32a to the inner wall of the housing 100, and the second end portion 32B can selectively abut one of the protrusions 5.

When the shell 100 and the cup body 102 are assembled, the projection 5 is completely immersed in the groove 4, the projection 5 jacks up the second end 32b of the connecting rod 32, the conductive sheet 33 is stopped to abut against the metal contact 11, the conductive sheet is located at a separation position at the moment, when the conductive sheet 33 does not abut against the first metal contact 11a and the second metal contact 11b, the second switch assembly is in a disconnected state, the second switch assembly 3 sends a signal to the circuit board 1, when the first switch is closed, the control device 105 controls the motor 103 to normally work, and the spring 31 contracts and deforms.

In another embodiment, the second switch and the motor 103 form a parallel circuit, when the second switch 3 is in an off state, the motor 103 is connected in series with the first switch 2, and when the first switch 2 is turned on, the motor 103 is started; when the second switch 3 is in a closed state, because the motor 103 is connected in parallel with the second switch 3, the motor 103 is short-circuited, and the food processor cannot be started.

When the shell 100 is separated from the cup body 102, the conductive sheet is located at the connection position, the conductive sheet 33 abuts against the first metal contact 11a and the second metal contact 11b, the second switch is in an on state, and the food processor cannot be started, so that the food processor is prevented from being started by mistake when the food processor is not used.

With reference to fig. 4 and 5, the grooves 4 are circumferentially arranged around the motor 103, and the protrusions 5 are correspondingly circumferentially arranged, so that when a user uses the electric cup, the protrusions can be aligned with the grooves by rotating the shell or the cup body at a small angle, thereby starting the machine.

Further, when the cup body 102 is not assembled with the housing 100 (i.e., the food processor is not used), the spring 31 acts on the abutting surface 321b, and under the action of the elastic force and the gravity, the conductive sheet 33 abuts against the first metal contact 11a and the second metal contact 11b to electrically connect the first metal contact 11a and the second metal contact 11b, and the second end 32b of the connecting rod 32 protrudes from the housing 100. At this moment second switch 3 is in the on-state, because of motor 103 with second switch 3 is parallelly connected, motor 103 then is by the short circuit, and the machine is unable to work, cuts off the food processor and starts the possibility of machine because of the mistake touches the switch when not using, and is more safe effective.

Although the present application has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the application, and all changes, substitutions and alterations that fall within the spirit and scope of the application are to be understood as being covered by the following claims.
