How electric mosquito swatters work

How electric mosquito swatters work

Electric mosquito swatters mainly use 4V rechargeable high-capacity lead-acid batteries or 2.4v NiMH/NiCd batteries, and dry batteries are also useful. During work, a high voltage of about 1850V DC is generated between the double-layer power grids through the booster circuit (the current is less than 10 mA, which is harmless to humans and animals). The electrostatic field between the two power grids has a strong adsorption force. When pests get close to the grid, they can be sucked into the grid, and the short-circuit current generated will immediately kill them. Electricity

What does the term lumens in table lamps mean?

What does the term lumens in table lamps mean?

Lumen is a physical unit describing luminous flux, which is explained by physics as the total emitted luminous flux produced by a candle in a solid angle. It is defined in terms of candela sphere angle (cd times sr). A lumen is the amount of light emitted in 1 spherical angle unit, emitting the same amount of energy in all directions from the light source, and the intensity is 1cd. 1 lumen is equal to 1.46 milliwatts (1.46 x 10^-3W) of radiated electromagnetic energy (EM) at a frequency of 540 terahertz (540 THz or 5.40 x 10 Hz). Reduced to the SI base unit, 1 lumen is equal to 0.00146 kilograms square meters per second cubed (1.46 x 10 kilograms times m/s).

Precautions for the use of electric mosquito swatters

Precautions for the use of electric mosquito swatters

1. When attacking mosquitoes, press the switch, swing the mosquito swatter, and the mosquitoes will be killed with a light touch. 2. Mosquito swatters killed by the net surface, please shake the net to make it fall off, do not rinse with water to prevent short circuit. 3. The climate is humid, the mosquito swatter may absorb moisture without high pressure or become low pressure, and the killing effect will decrease. You should use a hair dryer to dry it in time or dry it in the sun, and the effect of the mosquito swatter will automatically recover. 4. The electric mosquito swatter works on DC high voltage and will produce sparks of a certain intensity. Therefore, it is strictly forbidden to use and overhaul in places full of flammable gases, and avoid touching the high-voltage power grid with hands or conductive metal rods when electrified to prevent accidents. Electric mosquito swatters are not toys and should not be used by children.
