The invention relates to the field of medical electrocardio signal guarding, in particular to an electrocardio leading mode intelligent switching method and an electrocardio leading mode intelligent switching device. The lead automatic switching technology is used for avoiding the problem that an electrocardio signal can not be measured due to the fact that a driving lead wire drops. A user can continue to measure the electrocardio signal without manually switching to other modes or reconnecting the driving lead wire. The electrocardio leading mode intelligent switching device is time-saving, convenient and better in user experience.

An automated hinge assembly has at least two leaves and a driving member. The leaves respectively connect securely to a cover and a body of a portable electronic device and are connected pivotally together. The driving member is mounted between the leaves and has a resilient element, a stationary bracket and a sliding bracket. The resilient element provides a force to automatically pivot a moving leaf from a stationary leaf. The stationary bracket has at least one inclined surface formed circularly around a central axis. The sliding bracket is pushed by the resilient element and has at least one protrusion corresponding to and abutting the inclined surface of the stationary bracket, thereby generating a torque to drive the leaf connected to the stationary bracket to rotate relative to another leaf.

The invention discloses drinking water clarification disinfecting pills and a preparation method. The drinking water clarification disinfecting pills are prepared by the following steps of: mixing polyaluminium chloride, chitosan, anhydrous sodium sulfite and anhydrous sodium carbonate to obtain a first mixture; mixing the first mixture, resin powder and talcpowder; tabletting the mixture into an inner layer core by using a tablet machine; coating the inner layer core with solution of shell-lac ethanol; mixing sodium dichloro isocyanurate and the resin powder to obtain a second mixture; rolling the second mixture on the surface of the coated inner layer core by using a sugar coating machine; and spraying aqueous solution of ethanol on the pills to prepare the drinking water clarification disinfecting pills. The drinking water clarification disinfecting pills of the invention have the advantages of time-saving and convenient use, easy carrying, and excellent turbid water clarification effect. The microorganism index of water treated by the drinking water clarification disinfecting pills is accordant with the national drinking water standard and the drinking water clarification disinfecting pills are suitable for military personnel, fieldwork personnel and tourists to treat and use the field drinking water.

The invention discloses a guiding hand-held micro atomizer comprising an atomizer main body and an atomization piece which is arranged in the atomizer main body; a guiding spray pipe which is inclined outwards extends upwards from the side surface of the atomizer main body; the atomization piece is vertically arranged in the atomizer main body and faces the input port of the guiding spray pipe; an angle is formed between a mist output plane of the atomization piece and the extending direction of the guiding spray pipe, and the angle is less than 90 degrees; in such a manner, because the guiding spray pipe which is inclined outwards extends upwards from the side surface of the atomizer main body, the angle is formed between the mist output plane of the atomization piece and the extending direction of the guiding spray pipe and the angle is less than 90 degrees, the guiding spray pipe plays a good guiding role to the mist, a traditional direct spraying method is replaced, the mist spraying is centralized and not scattered; meanwhile, a user does not feel uncomfortable; and the guiding hand-held micro atomizer is compacted in appearance, can be held by hand and is very convenient to use.

A storage device adapted for portable device and suitable to be installed in luggage includes an inner housing, an outer housing and a base. The inner housing includes two parallel vertical side walls and a transverse base wall connected to bottoms of the vertical side walls.
