Abstract: A liquid spray device with concealed electric conductive structure is used for atomizing the liquid stored therein and then spraying the atomized liquid. The device comprises a base, a controller on a front side of the base, a liquid storage container that can be separately arranged above or below the controller, a sprayer including a bracket movably pivoted on the controller, a vibrator arranged on the bracket, a liquid sucking outlet that allows the vibrator to abut against the liquid storage container, and a housing covering the base. A conductive pivoting structure is provided between the controller and the bracket, the bracket is provided with a wire recess, and a wire is provided within the wire recess, which allows one end of the wire to be electrically connected to the conductive pivoting structure, while the other end thereof is electrically connected to the vibrator.

Abstract: The present utility model provides a toilet paper supply machine and identifiable toilet paper roll, in which the toilet paper roll supporting base of a supply machine body is provided with a motion sensing device, and two ends of the toilet paper roll each is associated with a cover tube, in which one outer tube portion of one cover tube is provided with a through hole, through which the toilet paper roll is mounted to the supply machine body, such that when the motion sensing device is covered by the outer tube, the motion sensing device can identify the through hole; in addition, a cutting device arranged within the supply machine body is further provided with a stopping device, in the case when the motion sensing device senses that the toilet paper roll is an incorrect one or an unqualified one, the stopping device is started to stop the cutting device, such that the cutting device is stopped from cutting the toilet paper.

Abstract: An automatic synchronous soap dispensing and paper towel supply device comprises a soap dispensing device and a paper towel supply device.

Abstract: A liquid spray device with concealed electric conductive structure is used for atomizing the liquid stored therein and then spraying the atomized liquid. The device comprises a base, a control means arranged on a front side of the base, a liquid storage means that can be separately arranged above or below the control means, a spraying means, which comprises a bracket movably pivoted on the control means, a vibrator arranged on the bracket, a liquid sucking outlet that allows the vibrator to abut against the liquid storage means, and a housing covering the base; in particular, a conductive pivoting structure is provided between the control means and the bracket, the bracket is provided with a wire recess, and a wire is provided within the wire recess, which allows one end of the wire is electrically connected to the conductive pivoting structure, while the other end thereof is electrically connected to the vibrator.

Abstract: A wire cut electric discharge machine having rollers is disclosed. It has a wire electrode disposed in a working zone of the electric discharge machine. This wire electrode is rolled by a rolling device so that the cross-sectional area of this wire electrode changes from a circular area into an elongated one. After rolled, the wire electrode has two parallel rolled flat surfaces. The working width between these flat surfaces is smaller than the original diameter of the wire electrode before rolled. So, the cutting width is narrower than before. By using the rolled wire electrode, this invention can reduce the cutting width limit. I can improve the precision of the product, without changing the material property of the wire electrode. And, it can reduce the cost of the wire electrode.

Abstract: A wire cut electric discharge machine having several wire electrode sets is disclosed. It mainly includes a cutting machine, several wire electrode sets, and an adjustable unit. Each electrode set has an upper guiding seat, a lower guiding seat, and a wire electrode. Two ends of each wire electrode can be adjusted independently so that the cutting conditions on the workpiece can be easily and precisely adjusted. Hence, the cutting angles can be adjusted independently and the cutting precision is raised than before.
