It is equipped with sealing-plug 201；Sealing-plug 201 is made up of the material for being dissolved in water, or sealing-plug 201 by with water react generation gas or
The material of solution is made.
After children wear the wrist-watch with the watchband, if unexpected slip is dropped in water, sealing-plug 201 connects with water immediately
Touch, the material for being made up due to sealing-plug 201 of the material for being dissolved in water or gas or solution being generated by being reacted with water is made, then close
Blocking 201, which meets water, can not then play the effect of sealing.Because now the pressure in chamber 103 is less than the pressure in extraneous water, enter
Liquid mouth 102 is entered in chamber under pressure after sealing-plug failure in the state opened, extraneous water.Due to chamber
The chemical substance that generation gas is reacted with water is filled with 103, then into the water in chamber 103 and chemical reaction generation gas
Body.When the pressure in chamber is equal to or more than the pressure of extraneous water, inlet is closed.And the chemical substance in chamber still with
The water reaction generation gas of entrance, as gas is more and more, gas gradually can support bar shaped main body made of elastomeric material greatly,
Untill reaction terminates.Bar shaped main body supports big process equivalent to the process to balloon inflating.Because wrist-watch is worn on children
On arm, support big watchband and take children on the water surface out of in buoyancy, so as to avoid unexpected slip from dropping in water
Children sink under water drowned.
Preferably, inlet 102 is cone, and the side opening positioned at the external world is big, and the side opening in chamber is small；
The small side that is open is provided with resilient rubbber cushion 202；Pressure of the resilient rubbber cushion 202 in chamber 103 is equal to or more than the external world
