Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Terms used herein, including technical and scientific terms, have the same meaning as terms commonly understood by one of ordinary skill in the art, unless otherwise defined. It will be understood that terms defined in commonly used dictionaries have meanings that are consistent with their meanings in the prior art.

Referring to fig. 1-4, a portable household mobile phone charging device is characterized in that: comprises a USB charger body 1; the table top is provided with a counter bore 2 relative to the USB charger body 1; the USB charger body 1 is embedded in the counter bore 2; the USB charger body 1 is electrically connected with the patch board base through a power line; a fixed filling layer is arranged in the counter bore 2 relative to the USB charger body; a charging circuit board is arranged in the USB charger body; the charging circuit board is respectively connected with the power line and the USB output interface 1.1.

Furthermore, the fixed filling layer is glass cement; the surface of the USB charger body 1 is flush with the table top 3; the counterbore phi 50 x 20.

In this embodiment, the USB charger body 1 is installed in an embedded manner, and is installed in a direction from top to bottom on a counterbored platform, and before installation, a small amount of glass cement (which cannot be too much and is difficult to clean) needs to be deposited inside the counterbored hole for fixing.
