Description

Technical Field

[0001] The present application relates to the field of household appliances, and in particular to a food processor. Background Art

[0002] With the development of science and technology, more and more food processors have replaced manual tools and entered people's lives. On the one hand, food processors can greatly improve work efficiency. On the other hand, food processors have also improved people's quality of life to a certain extent.

[0003] The existing food processor has a motor, a switch control device and an operating unit (blade, etc.). The machine accessories include sharp blades. When the food processor is working, the blades rotate at high speed. The machine itself needs to have a safety protection structure to prevent accidents caused by accidental touch. Therefore, it is important to pay attention to the safety protection design of the food processor. Utility Model Content

[0004] The purpose of this application is to overcome the deficiencies in the prior art and to provide an improved food processor that requires the installation of a cup body and then triggering a safety switch to start the machine, thereby making the safety switch structure of the food processor safer and more reliable and greatly reducing the risk for users during operation.

[0005] The present application provides a food processing machine, comprising a casing, a motor installed on the casing, a controller and a safety switch, wherein the motor and the safety switch are electrically connected to the controller respectively, and when the safety switch is triggered, the controller allows the motor to receive electrical energy. The food processing machine also includes an operating member and a triggering member, and the safety switch includes a triggering part, and the operating member abuts against the safety switch and is configured to drive the safety switch to move when subjected to force, so that the triggering part of the safety switch cooperates with the triggering member to trigger the safety switch.

[0006] Furthermore, the food processor comprises a first slide groove for the trigger member to slide and a second slide groove for the safety switch to slide, and the first slide groove is connected to the second slide groove.

[0007] Furthermore, the first slide groove and the second slide groove are arranged in a "T" shape, and the trigger member includes an abutment portion, and the abutment portion pushes the trigger portion at a penetration point between the first slide groove and the second slide groove, thereby triggering the safety switch.

[0008] Furthermore, the housing includes a base and a cup body. When the cup body is assembled to the base, the trigger member slides along the first slide groove under the action of external force, so that the trigger member and the trigger part are not in contact or only in contact without relative extrusion, and the safety switch is in an untriggered state; when the trigger member and the operating member are in the same pressed state, the trigger part is squeezed by the trigger member, and the safety switch is in a triggered state.

[0009] Furthermore, the food processor includes a first return spring and a second return spring, wherein the first return spring is sleeved on the trigger member and configured to reset the trigger member; the second return spring presses against the safety switch and is configured to reset the safety switch and the operating member.

[0010] Furthermore, the front end of the abutting portion is provided with an inclined surface for driving the triggering portion on the safety switch, and the inclined surface is more likely to apply force to the triggering portion.

[0011] Furthermore, one end of the trigger member away from the safety switch passes through the first slide groove and is exposed on the machine base. When the cup body is installed on the base, the cup body presses the trigger member so that the trigger member slides in the first slide groove, and the trigger member does not contact the trigger part or only contacts with the trigger part without relative extrusion.

[0012] Furthermore, the safety switch is a micro switch, and the operating element is a button or a knob.

[0013] Furthermore, the base includes a limiting portion provided on the first sliding groove, one end of the first reset spring abuts against the limiting portion, and the other end of the first reset spring abuts against the trigger member to reset the trigger member.

[0014] Furthermore, the safety switch includes a sealing ring, which is sleeved on the trigger member so that the liquid in the cup body will not enter the motor through the first slide groove, thereby damaging the motor.

[0015] When the cup body is assembled to the machine base, the trigger member slides along the first slide groove under the action of external force, the trigger member approaches the trigger part, and the safety switch is in an untriggered state; when the trigger member and the operating member are both in a pressed state, the trigger part is squeezed by the trigger member, and the safety switch is in a triggered state. When the user uses the machine, the cup body must be installed and then the operating member is pressed, so that the food processor can work normally, which greatly reduces the user's operating risk.

The operating member 2 abuts against the safety switch 1 and is configured to drive the safety switch 1 to move when subjected to force, so that the triggering portion 11 of the safety switch 1 cooperates with the triggering member 3 to trigger the safety switch 1 .

[0023] The housing 101 includes a base 102 and a cup body 103. When the cup body 103 is assembled to the base 102, the trigger member 3 slides along the first slide groove 4 under the action of external force, so that the trigger member 3 and the trigger part 11 are not in contact or only in contact without relative extrusion, and the safety switch 1 is in an untriggered state; when the trigger member 3 and the operating member 2 are in the same pressed state, the trigger part 11 is squeezed by the trigger member 3, and the safety switch 1 is in a triggered state.
