Automatic fire extinguishing system for liquid crystal display television

Abstract

The invention relates to the field of liquid crystal display television equipment, in particular to an automatic fire extinguishing system for a liquid crystal display television. The automatic fire extinguishing system comprises a television shell, a liquid crystal screen module and a circuit module. The television shell and the liquid crystal screen module are connected in a matched manner. The circuit module is arranged in a space formed by the television shell and the liquid crystal screen module. Vent holes are formed in the television shell. A snap-through type double-metal-sheet temperature controller, a baffle, a connecting rod, a torsion spring, a limiting and buckling mechanism and a hopping connecting rod are arranged in the space formed by the television shell and the liquid crystal screen module. The snap-through type double-metal-sheet temperature controller is driven by the hopping connecting rod and the connecting rod, the limiting and buckling mechanism loses the limit to the baffle, and the vent holes can be covered with the baffle under the effect of the torsion spring. The automatic fire extinguishing system for the liquid crystal display television is simple in structure and high in safety.

Description

technical field [0001] The invention relates to the field of liquid crystal television equipment, in particular to an automatic fire extinguishing system for liquid crystal televisions. Background technique [0002] With the development of society, LCD TVs have been popularized, and almost every household has LCD TVs installed. According to relevant statistics, the sales volume of LCD TVs in China in 2016 was 46 million units. By the end of 2015, the total number of LCD TVs in possession More than 370 million units. The safe use period of LCD TVs is 7 years, and over-age use hides serious safety hazards. The interior of the LCD TV contains circuit modules such as power supply boards and signal processing boards, which are covered with various electronic components that transmit high voltage and high current. Humid environment, component aging, voltage instability, dust intrusion, etc. may cause the components to short-circuit and burn. It is the ignition point of TV sponta...

The safe use period of LCD TVs is 7 years, and over-age use hides serious safety hazards

The interior of the LCD TV contains circuit modules such as power supply boards and signal processing boards, which are covered with various electronic components that transmit high voltage and high current. Humid environment, component aging, voltage instability, dust intrusion, etc. may cause the components to short-circuit and burn. It is the ignition point of spontaneous combustion of the TV, which in turn will ignite the furniture, resulting in serious consequences of property burning and personal injury. The safety of LCD TVs is low.
