Abstract

A bathtub lifting chair comprises a base, a seat component, a lifting component and a controller. The seat component consists of a seat plate, a back plate and lateral wings. The bathtub lifting chair is characterized in that the lifting component comprises an inner arm, an outer arm, a push tube, a fan and a push rod, the push tube is positioned behind the back plate, the motor is connected with one side of the push tube, the push rod is positioned inside the push tube, the inner arm and the outer arm are two arms with equal lengths, centers of the two arms with equal lengths can be connected with each other by a rotatable shaft, the lower end of the inner arm is connected with the rear end of the base, the upper end of the inner arm is slidably connected with the lower side of the seat plate, the upper end of the outer arm is connected with the lower rear end of the seat plate, the lower end of the outer arm is slidably connected with the upper side of the base, the lower end of the push rod is detachably connected with the base, and the motor is connected with the push rod via a lead screw. A worm gear and a worm in the push rod are driven to act by the motor, so that the inner arm and the outer arm move along respective sliding tracks, and the purpose of lifting the bathtub lifting chair is achieved. The lateral wings on two sides of the seat plate are erected at the upper edge of a bathtub after being opened, a user only needs to sit on the lateral wings from the outside of the bathtub, then moves two legs into the bathtub and feels more comfortable during bathing since the inclination angle of the back plate can be adjusted.

Description
