DETAILED DESCRIPTION

[0021] The specific embodiments of the utility model will be further described below with reference to the drawings. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation on the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Referring to Figures 1-5 The utility model discloses a stirring machine with safety switch touch structure, including cup body (not shown in drawing), base 3, the motor is set in the base, lower clutch (not shown in drawing), the motor drives lower clutch rotation, still including tool holder 2, the tool holder with cup body, base are detachably connected, the base is provided with safety switch, the tool holder sets up stirring knife 15 and upper clutch 7, the tool holder is equipped with switch through slot 8, and the first sealing ring 10 covers switch through slot 8, and switch movable block 50 is set in switch through slot, and switch movable block presses switch top rod 51, and switch movable block moves down in switch through slot and promotes switch top rod to go down, and then touch safety switch. The tool holder is installed with tool holder seat, and the stirring knife is installed on the tool shaft of tool holder seat, and the upper clutch 7 is connected with the tool shaft, when the upper clutch rotates at high speed, drives the stirring knife to rotate, thereby breaking food.

[0023] The jacking spring 52 is arranged between the spring seat 53 and the switch top rod 51, when the cup body leaves the tool holder, the opening edge of the cup body fails to exert pressure on the first sealing ring 10, so that the jacking spring 52 can jacks up the switch movable block 50, the switch top rod 51 no longer presses the safety switch, and the safety switch is closed.

[0024] The tool holder 2 is provided with a finger blocking block 9, and the switch through slot 8 is located between the finger blocking block 9 and the outer vertical wall of the tool holder, and the distance between the finger blocking block and the outer vertical wall is less than the width of the finger. Therefore, the finger cannot be inserted into the gap above the switch through slot, preventing the safety switch from being touched by mistake.

[0025] The switch through slot includes a slot hole 81 and a pair of supporting plates 82, the pair of supporting plates 82 are located on two opposite sides of the approximately rectangular slot hole respectively, and the slot hole 81 is clamped between the two supporting plates, and the switch movable block 50 includes a shelf plate 501 and a vertical plate 502, the shelf plate 501 is placed on the pair of supporting plates 82, and the vertical plate 502 is inserted into the slot hole 501.

[0026] Opposite slot hole walls of the switch through slot 8 are respectively provided with a limiting block 83, and the two sides of the vertical plate 502 are respectively provided with an anti-withdrawal block 503, the limiting block is located above the anti-withdrawal block and limits the anti-withdrawal block from being pulled out upwardly from the slot hole.

[0027] The shelf plate 501 is provided with a shelf plate notch 504, and the shelf plate notch is used for avoiding the limiting block 83.

[0028] The bottom side of the vertical plate 502 is provided with a wedge surface 505 for guiding the vertical plate to pass over the limiting block 83, so that the anti-dropping block 503 passes through the switch through slot and is located below the limiting block 83.

[0029] As a further improvement, the first sealing ring is provided with a hollow sleeve (not shown in the figure), and the finger block is adapted to be inserted into the hollow sleeve, so that the first sealing ring can be easily pulled out by holding the hollow sleeve with hand when it is needed to be taken out from the tool holder for cleaning.

[0030] The working principle of the utility model is as follows: the tool holder can be taken off from the cup body or the machine base, so that the stirring knife can be conveniently cleaned alone. When the tool holder is installed on the machine base, the upper clutch and the lower clutch are coupled, then the cup body is installed on the tool holder, the bottom of the cup body is provided with an opening, the edge of the opening presses the first sealing ring, the switch movable block overcomes the elastic force of the lifting spring, the switch top rod 51 is pushed downward, the safety switch is pressed, the switch circuit is connected, at this time, if the motor is started, the motor drives the upper clutch, so that the stirring knife rotates at high speed. When the cup body is taken off from the tool holder, the lifting spring pushes the switch movable block upward, the first sealing ring is partially lifted, at this time, the safety switch disconnects the switch circuit, even if the button of the motor is pressed by mistake, the motor cannot be powered on.

[0031] The embodiments of the utility model are described in detail in combination with the drawings, but the utility model is not limited to the described embodiments.
