Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given in this aspect without any inventive step, are within the scope of the present invention.

As shown in figures 1-7, the utility model relates to a safety device of improved generation food processor, the bottom including the host computer body, the main cup body can cup joint with the tool post platform on the host computer body to the safety switch who will establish in the tool post platform detains inside, prevents the maloperation of staff touching production among the food processing procedure. The cup cover can be buckled at the opening part of the main cup body and is fixedly connected with the accommodating cup, the push cylinder can be pushed towards the inside of the accommodating cup along the opening part of the accommodating cup, and the outer edge of the side wall of the upper end of the push cylinder is provided with a probe; the outer wall that holds the cup has linked firmly the safety location box, the safety location box comprises box body and the detachable slider cover that links firmly with holding the cup, the top at the slider cover is established to the locating hole, the draw-in groove is transversely established on the lateral wall of slider cover, the lower part of box body is outstanding to be equipped with the fixed part, the slider cover passes through fixed part and box body fixed connection, thereby formed one and held the cavity of activity including the safety slider, box body upper portion opening can hold the probe and continuously stretch into, the safety slider is the font of falling L, the slider head can cover the oral area at the box body, the both sides of slider head respectively are equipped with a lateral bulge, support respectively on the both sides wall of slider cover inside, the one end of first elastic construction that resets supports on the outer wall of box body.

The outer wall of the main cup body is provided with a handle, the push rod sleeve can be fixedly connected with the handle of the main cup body in a buckling mode, so that a cavity capable of containing the safe push rod is formed, one end of the second reset elastic structure abuts against the outer wall of the handle of the main cup body, and the other end of the second reset elastic structure abuts against the safe push rod.

The utility model discloses an action principle: food is firstly put in the containing cup, the cup cover is buckled on the main cup body, the bottom of the main cup body is buckled with the tool apron table of the main machine body, the push cylinder is continuously inserted into the containing cup, firstly, the cylinder bottom of the push cylinder extends into the containing cup and covers the cup mouth of the containing cup, then the probe penetrates through the positioning hole of the sliding sleeve and abuts against the sliding block head of the safety sliding block, so as to push the sliding block head to overcome the elastic force of the first reset elastic structure to move downwards, so that the lateral projection which is propped against the side wall of the sliding sleeve also moves downwards along the side wall of the sliding sleeve, along with the downward movement of the safety slide block, the slide block tail of the safety slide block passes through the bottom of the safety positioning box and is propped against the safety push rod in the main cup body, and then the safety push rod is pushed to overcome the elasticity of the second reset elastic structure to move downwards, when the downward stroke E of the safety slide block and the safety push rod reaches about 5mm, the safety push rod is abutted and triggers the safety switch, so that the motor is started to start the food processing process. At the moment, the lateral projection of the sliding block head slides into the clamping groove under the pushing of the probe, and the transverse displacement is simultaneously blocked by the blocking table and does not move downwards any more, so that the linkage reaction with the safety push rod is stopped, and the safety push rod is kept in a stable triggering state with the safety switch at the moment.

Since the main function of the pusher is to press the food to be processed in the receiving cup, the pusher should not be affected by the safety pusher stopping its downward movement, but should continue its downward movement to press the food. At the moment, the probe can easily pass through the gap due to the gap generated by the transverse displacement or deformation and restoration of the sliding block head and can continuously and freely descend in the safety positioning box, so that the downward movement of the push cylinder fixedly connected with the probe is not hindered.

After the food is processed, the push cylinder is pulled out of the containing cup, the probe fixedly connected with the push cylinder is pulled out of the safety slide block, the safety slide block is acted upwards by the elastic force of the first reset elastic structure and moves upwards along the inclined table of the clamping groove, so that the safety slide block is pulled out of the clamping groove upwards and returns to an initial position close to the upper end of the slide block sleeve, and the safety push rod is also separated from the action of the safety slide block and returns under the elastic force of the second reset elastic structure.

It should be noted that the embodiments are merely illustrative of the present invention, and any equivalent transformation that conforms to the essential principle of the technical solution should be within the protection scope of the present invention.
