A switch structure including a switch member that is turned on by a button is provided.

[Problems to be solved by the device]

However, in this type of switch structure, the regulating member is always urged by the elastic force of the elastic member in the direction opposite to the mounting rotation direction of the lid. Therefore, when the switch button is not pressed down while the lid is attached, there is a problem that the lid is rotated in the non-attaching direction and comes off through the operating piece that abuts against the regulating member. There is. Further, when the switch button is pressed, the shaft provided in the switch button is inserted into the hole provided in the regulation member to enable the switch button to be rotated. Therefore, when the lid is attached, the attaching / rotating operation must be performed so that the hole of the regulating member that abuts on the actuating piece is aligned with the axis of the switch button, resulting in poor workability. The present invention was devised to solve the above-mentioned conventional drawbacks, and its purpose is to prevent the lid body from coming off when the switch button is not pressed and to simplify the attachment work of the lid body. It is an object of the present invention to provide a switch structure of a small electric cooking device which can be turned on and can turn on the switch member only when the lid is attached.

[Means for solving problems]

A dish member that can be inserted and removed and attached detachably,
A blade member that is removably attached to the rotating shaft through which the dish member is inserted, a lid that is removably attached to the drive unit or the dish member, and has a discharge guide unit at the tip and an input unit that communicates with the inside on the upper surface. In a small electric cooking apparatus comprising a body, an operating rod movably supported by a grip portion, a switch button attached to one end of the operating rod,
With respect to the first elastic member that always urges the operating rod toward the switch button by its elastic force, and the other end of the operating rod,
A switch member attached with a gap having a width corresponding to the movement stroke of the switch button and a gripper or a drive unit corresponding to the gap are movably supported and abut on an operating piece of a lid attached to one end. A contact member and a slide member having a spacer portion at the other end that can enter the gap, and a second elastic member that moves the slide member so that the spacer portion is always located outside the gap, When the lid is attached, the operating piece abuts and moves the spacer part of the slide member into the gap, and the operating rod that moves when the switch button is pressed turns on the switch member via the spacer part. It is characterized by being operable.

[Function of the invention]

Since the present invention is configured as described above, when the lid is not attached to the drive unit or the dish member, the spacer member has a gap due to the elastic force of the second elastic member. It has been moved to be located outside. In this state, when the switch button, that is, the operating rod is moved against the first elastic member, the width of the gap is set to be equal to or larger than the moving stroke of the operating rod, so that the operating rod contacts the switch member. Contact is restricted and kept in the OFF state. On the contrary, when the lid is attached, the spacer member moves against the elastic force of the second elastic member by contact with the actuating piece, and the spacer portion is positioned in the gap. When the switch button is pressed in this state, the operating rod turns on the switch member via the spacer portion located in the gap.
