Abstract

The invention discloses a hourglass convenient in accurately controlling timing duration. The hourglass comprises a cylindrical upper funnel and a cylindrical lower funnel which are made of transparent glass, and further comprises a ball valve, scale marks and a circular-truncated-cone-shaped base, the cylindrical upper funnel and the cylindrical lower funnel are provided with a cylindrical upper cavity and a cylindrical lower cavity respectively and an upper circular-truncated-cone-shaped cavity and a lower circular-truncated-cone-shaped cavity which are communicated, and the upper circular-truncated-cone-shaped cavity and the lower circular-truncated-cone-shaped cavity are provided with an upper sand leaking passage hole and a lower sand leaking passage hole which are communicated respectively; the ball valve comprises a rotating shaft, a handle and a ball with a second round through hole, the ball is arranged in the upper sand leaking passage hole, a noctilucent coating is arranged on the surface of a steel ball, the scale marks comprise upper scale marks, lower scale marks and corresponding numerical values, the upper end of the circular-truncated-cone-shaped base is provided with a big round concave hole, and round nano micro-absorbing glue and release paper are arranged at the bottom end of the circular-truncated-cone-shaped base. The hourglass is capable of accurately controlling timing duration, simple in structure and attractive and elegant.

Description

technical field [0001] The invention relates to the technical field of hourglasses, in particular to an hourglass which is convenient for accurately grasping the timing. Background technique [0002] The hourglass is an ancient timekeeping device. It usually includes an upper funnel with an upper cavity, a lower funnel with a lower cavity, and a sand leakage channel hole connecting the upper cavity and the lower cavity. Fine sand can flow up and down between the upper funnel and the lower funnel through the sand leakage channel hole. . Existing hourglass can generally grasp timing situation, but can not accurately grasp timing length. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide an hourglass, which can not only accurately grasp the timing length, but also has a simple structure and is elegant in appearance. [0004] The technical solution of the present invention is to design and manu...
