  • Patent number: 10856518
    Abstract: An excrement collection device includes a casing having a bottom wall, two opposing first outer sidewalls, and a second outer sidewall connecting the first outer sidewalls; a receiving space defined by the bottom wall, the first outer sidewalls, and the second outer sidewall and divided into a temporary storage region and a collection region, with the temporary storage region disposed between the second outer sidewall and the collection region; a cleansing component disposed in the temporary storage region; and a support component disposed at the top of the temporary storage region and having rotatable support boards. Excrement left behind at home by pets because of defecation and urination is gathered in the collection region to thereby spare pet keepers the hassles of frequent cleansing, prevent exposure of the excrement to air for a long period of time, and preclude a foul-smelling odor otherwise lingering at home.

  • Publication number: 20060220521
    Abstract: An electrode structure is provided. The electrode structure contains a first auxiliary electrode and a second auxiliary electrode, a first edge electrode and a second edge electrode disposed between the first auxiliary electrode and the second auxiliary electrode, wherein the first edge electrode forming an electrode pair with the first auxiliary electrode and having a same polarity as that of the first auxiliary electrode and the second edge electrode forming an electrode pair with the second auxiliary electrode and having a same polarity as that of the second auxiliary electrode, and at least one middle electrode disposed between the first edge electrode and the second edge electrode. The electrode structure respectively enhance an interaction between the first edge electrode and the second edge electrode and a neighboring electrode by means of the first auxiliary electrode and the second auxiliary electrode. Alternatively, the width of the edge electrode increase to be 1.
