Abstract: A toilet seat cover with a full-directional night lamp includes an upper lid, a seat and two supports. A cylindrical night lamp is locked on the upper lid or locked between two seat shaft sleeves at two sides of the seat. The night lamp comprises at least one electric body and at least one light-pervious tube. The electric body has at least one end thereof defined as a light source end. The light source end of the electric body is axially sleeved on and fixed to the light-pervious tube. The whole night lamp can be detachably mounted on the upper lid or locked between the two seat shaft sleeves at two sides of the seat, thereby attaining a full 360 degree emission of light and allowing the lighting emission to be free of the operation state of the toilet seat cover.

Abstract: A toilet seat cover with an easily assembled and detached child seat includes an upper lid, a parent seat and a child seat. Two fixing shafts are respectively sleeved on two parent shaft sleeves. Two pins of two supports and the two fixing shafts are radially held with each other. Each of the two fixing shafts is axially inserted by a cylindrical shaft post. Two elastic c-shaped rings are respectively disposed at two ends of a child shaft sleeve and radially sleeved on the shaft post. At least one end of the child shaft sleeve disposes a central shaft which is radially inserted into a directional slot. When the child seat is not needed, the shaft post can be removed from the fixing shaft to attain a toilet seat cover with a common appearance.

Abstract: A vertical assembling and disassembling mechanism for a toilet seat includes a support, a fixing axle, and a turning member. A pin of the support can be inserted into or pulled out a radial pin hole of the fixing axle. The fixing axle includes a damper therein to connect with the turning member. The fixing axle is formed with a lock hole to receive a lock plate biased by a spring. A turning ring is provided to cooperate with the lock plate. The inner end of the lock plate is engaged with the pin. The inner wall of the turning ring is formed with an inverted step recess. When the turning ring is turned about 90±3 degrees, the outer end of the lock plate is engaged in the inverted step recess and the inner end of the lock plate is disengaged from an annular groove of the pin.

Abstract: A quick installation hinge seat of a closestool cover plate includes two hinge shafts and two support seats. Each hinge shaft has a pin hole for connection of a pin provided on each support seat. A button switch is mounted between the two hinge shafts to control the pin in the pin hole. The button switch includes a hinge pipe, a button seat, a lock control rod slidable in the radial direction of the hinge pipe, a spring, and a button to press the lock control rod. Two ends of the lock control rod are axially inserted in the two hinge shafts respectively and slideable radially. Each of the two ends of the lock control rod has a locking plate and an unlocking plate. The locking plate and the unlocking plate are arranged in a stagger manner. Each pin has a locking groove and an unlocking groove thereon.

Abstract: A quick-installation structure of a toilet seat cover assembly includes two positioning rods which are fixed on a toilet and two connection devices which are disposed on the toilet seat cover assembly and correspond to the two positioning rods, respectively. Each of the connecting devices includes a sleeve formed on a toilet seat, a rotating axle fixed to a cover, a connecting block connected to the rotating axle, a connecting sleeve fitted on the connecting block and a button connected to the connecting sleeve. The connecting block includes a main body, an engaging plate and a first restoration spring. The main body is longitudinally formed with a positioning hole. The engaging plate and the first restoration spring are laterally and pivotally connected to the main body above the positioning hole. The engaging plate is moved to swing by pressing the button. The positioning rod has an annular groove at an upper portion thereof and a cone with an inclined surface.

Abstract: A damping device comprises an axle, a housing, a unidirectional member, and a damping oil. The unidirectional member in cross section is formed like a T-shape, and a top portion thereof is formed as an arc to cooperate with the housing's inner wall. Where the unidirectional member contains a U-shaped slot is defined oil holes interlaced with the gap of the first slot wall. The lifting of the cover generates little damping and the closing thereof generates a variable and yet optimal damping. The undersized unidirectional member also adds strength to the structure. The diminished cross-section of the unidirectional member contributes to a smaller U-shaped slot.
