Abstract

The hourglass with signal shielding function according to the present invention comprises a first bowl-shaped body, which is a double-layer structure, a first cavity is formed between the inner wall and the outer wall, and the side with a smaller diameter has an opening; the second bowl-shaped body, It is a double-layer structure, a second cavity is formed between the inner wall and the outer wall, and there is an opening on the side with a smaller diameter. The second cavity has the same volume as the first cavity; the connecting piece is a hollow structure, One end communicates with the smaller diameter side of the first bowl, and the other end communicates with the smaller diameter side of the second bowl; metal powder is placed in the first cavity and / or the second bowl In the second cavity, the volume of the metal powder is equal to the volume of the first cavity and the second cavity, and the metal powder can be in the first cavity, the connecting piece and the second cavity flows between. This solution uses the characteristics of the hourglass to gradually shield the network signal and gradually slow down the network speed.

Description

technical field [0001] The invention relates to the technical field of signal shielding, in particular to an hourglass with a signal shielding function. Background technique [0002] The shielding box is a shielding body of various shapes such as shells, plates, and sleeves made of conductive or magnetically conductive materials, which can limit the electromagnetic capability within a certain space and be used to suppress radiation interference. The existing shielding box can only completely shield the signal at one time, and it is good to place the shielded object directly in the shielding box, but in some special cases, for example, the router in the user's home may need to be blocked at night before the user goes to sleep. Use network signals, listen to music, download files, etc. At this time, you may need to set the shielding time of the router, and set the signal strength of the router to gradually weaken according to your own needs for network signals, until finally t...
