Sterilizing device and driving method thereof

Abstract

The invention provides a sterilizing device and a driving method thereof. The sterilizing device comprises at least one lamp holder and at least one ultraviolet radiator, wherein each lamp holder comprises an electronic ballast; each ultraviolet radiator comprises an upper cover, two lamp tube pin glass sleeves, a U-shaped thermal cathode ultraviolet lamp tube, a lower cover and a metal insertingneedle; the two lamp tube pin glass sleeves of each ultraviolet radiator are fixedly mounted on the upper cover; a cathode end of each U-shaped thermal cathode ultraviolet lamp tube faces downwards; two pins of each U-shaped thermal cathode ultraviolet lamp tube are separately inserted in the two corresponding lamp tube pin glass sleeves; a U-shaped cold end of each U-shaped thermal cathode ultraviolet lamp tube is mounted upwards; the tube diameter range of each U-shaped thermal cathode ultraviolet lamp tube is between 4 nm and 5 nm; the lower cover is in matched connection with the upper cover; the metal inserting needle is arranged on the lower cover; after each ultraviolet radiator is inserted in the corresponding lamp holder through the corresponding metal inserting needle, the corresponding electronic ballast supplies power for the corresponding ultraviolet radiator through the corresponding lamp holder via the corresponding metal inserting needle, thus, the U-shaped thermal cathode ultraviolet lamp tubes produce 185 nm ultraviolet rays, and the generated 185 nm ultraviolet rays react with oxygen in air to generate ozone.

Description

technical field [0001] The invention relates to the technical field of disinfection, and specifically provides a disinfection device and a driving method thereof for disinfection using ultraviolet lamps. Background technique [0002] The humidity in southern my country has been around 80% to 95% for a long time, and the items in various cabinets in the home are prone to mildew. Even the walls of the cabinets are full of mold, and the flowers even emit a disgusting smell. Irradiation with ordinary ultraviolet lamp tubes can effectively kill the mold near the radiation lamp tube, but the items that are farther away from the radiation source lamp tube or are covered, such as a locker, can't control the effect of the latter one. Even the front of the clothes can't control the lining; the food cabinet is even more difficult to achieve the effect, and the items are placed in the container, especially glass and ceramic bottles, and the 253.7nm ultraviolet radiation cannot penetrate...

Problems solved by technology

Irradiation with ordinary ultraviolet lamp tubes can effectively kill the mold near the radiation lamp tube, but the items that are farther away from the radiation source lamp tube or are covered, such as a locker, can't control the effect of the latter one. Even the front of the clothes can't control the lining; the food cabinet is even more difficult to achieve the effect, and the items are placed in the container, especially glass and ceramic bottles, and the 253.7nm ultraviolet radiation cannot penetrate at all.

Thinking of buying an ozone generator, now the general industry uses pure oxygen to supply gas and then converts it to ozone O 3 , the efficiency is good, but the minimum power is several hundred watts, and the volume is too large, obviously cannot enter the home; the so-called ultra-small volume that can enter the home only hears the sound of high-voltage discharge and compressed gas, and the smell of ozone for a long time It didn't come out. Although it is said to be able to clean and decompose the pesticides left on vegetables and fruits by putting them in water, it is difficult to kill the mold in the cabinet. Therefore, I haven't seen any products on the market until now.
