Document Type and Number:
Japanese Patent JP5973584
Kind Code:
B2
Abstract:
The invention discloses a lighting/sounding device activated by inflation of a balloon, which comprises a lighting lamp/sounder, a battery, and a housing at least covering the lighting lamp/sounder. The housing comprises an inlet end, an outlet end, and an air channel connecting the inlet end and the outlet end to form a through passage for air flow within the housing. The lighting lamp/sounder is provided within the air channel and has a sealing device for sealing off the air channel. When the balloon is not inflated, the lighting lamp/sounder cannot be activated; after the balloon is inflated, a pressure difference generated between inside and outside the balloon pushes the lighting lamp/sounder towards the outer end of the air channel and seals the air channel; and, when the air channel is sealed up, the electric circuit of the lighting lamp/sounder is closed and the lighting lamp/sounder is activated to operate.
