Abstract: Systems and methods are provided for detecting a sitting posture of a user on toilet and generating notifications for the user based on the detected sitting posture. A sitting posture detection and reminder mechanism measures a distance X between a distance sensor and a body of the user sitting on the toilet. The mechanism calculates an angle ? between the user's spine and the user's thighs based on the measured distance X and generates a sitting posture notification for the user based on the calculated angle ?. The mechanism may operate a motor coupled to the toilet cover to automatically adjust an angle of the cover and guide the user into a healthy sitting posture.
Abstract: This is a type of connection device between a toilet and a drainpipe, including a trap with an inlet connected to a toilet flush port and an outlet connected to the drainpipe. The trap has a bend part and a horizontal lower pipe connected to it. Upper and lower inner pipe walls of the horizontal lower pipe have different declination angles. There is a containing part in the inlet; and in the containing part there is a sealing part forming a sealing structure between the flush port and the inlet. This simplifies the complex structure of existing toilet drainage parts for on-site installation and for reliable use. The separated trap design includes structure that can generate a siphon phenomenon. At the time of sale, wash-down drainage can be easily transformed to siphon wash-down drainage just by changing parts, such as the trap of the toilet, thus improving the drainage effect.

Abstract: An exemplary embodiment relates to an expansion bolt component that includes a bolt, an elastic component, and a nut. The bolt includes a necking part at an upper end thereof. The elastic component includes sides parts that include a plurality of ribs symmetrically arranged. Each rib includes a lower part and an upper part, each lower part being connected to a lower part of an associated adjacent rib. The nut is configured to be threaded onto a lower end of the bolt and to move into a lower end of the elastic component due to rotation of the bolt. The lower part of each rib is configured to expand in a radial direction when the nut moves into the elastic component. The upper part of each rib is configured to move simultaneously toward the upper part of its associated adjacent rib, such that the upper parts of the plurality of ribs clamp the necking part of the bolt.
