Sandglass device with controllable flow rate

Abstract

The invention provides a sandglass device, which is used for metering the time, and comprises a fixed support frame, a container and a certain amount of sand, wherein the container is arranged on thefixed support frame; the sand is accommodated in the container; the container comprises a first accommodating part and a second accommodating part which are mutually communicated. The sandglass deviceis characterized by also comprising a vibration motor, a motor driver and a control unit, wherein a communicating part communicated with the inside spaces of the first accommodating part and the second accommodating part is arranged between the first accommodating part and the second accommodating part; the communicating part comprises a first communication pipe and a second communication pipe; acertain included angle is formed between the extending direction of the first communication pipe and the extending direction of the second communication pipe. In order to solve the problem that the time of the sand totally flowing from one end to the other end is fixed, the sandglass device provided by the invention has the advantages that the natural flowing of the sand is blocked through the communication part; through the vibration by the vibration motor; the sand flows so that the time is controllable; meanwhile, relevant equipment assemblies difficult to set appearance are arranged in the fixed support frame; the requirement of an user on the appearance is also met.

Description

technical field [0001] The invention relates to an hourglass. Background technique [0002] The hourglass is a tool used by people to measure time, and every time the sand grains flow from one end, it represents the end of time. [0003] For some existing hourglasses, the time for sand grains to flow from one end to the other end is completely fixed and cannot be changed flexibly according to the needs of users. [0004] In order to solve the above problems, there are some hourglasses with controllable flow rate in the prior art, for example, hourglasses using a valve mechanism. Although such an hourglass can solve the problem of sand flow rate control, it increases the user's operation steps for the hourglass, and the exposed valve mechanism also makes the hourglass lose certain aesthetics. Contents of the invention [0005] In order to solve the above problems and provide an hourglass device with controllable flow rate and simple operation and beautiful appearance, the...
