Description

BACKGROUND OF THE PRESENT INVENTION Field of Invention The present invention relates to a sterilization and deodorization waste container, in particular a sterilization and deodorization waste container with dual-wave band ultraviolet lamp tube. The invention is adapted for waste containers with lids. Description of Related Arts Current household waste containers are generally equipped with lids configured to be opened by means of foot pedal, induction, gentle touch, and etc. In particular, in the waste container used in the kitchen, the kitchen waste disposed in the barrel is easy to breed bacteria and generate stinky smell, resulting in pollution of people's living environment. That further affects people's sense of smell and health and has health hazards. In order to solve the above problems, the current technology utilizes ultraviolet light wave for sterilization. That is, a direct ultraviolet lamp tube is installed in the waste container to sterilize the interior environment in the barrel, but this solution of using ultraviolet for direct sterilization has the following shortcomings: 1. The ultraviolet directly irradiated by ultraviolet lamp tube for sterilization can only propagate along a straight line, and thus there are more positions that cannot be irradiated and dead angles during the sterilization in the container. Therefore, its sterilization effect is relatively poor.2. In order to ensure light transmission and sterilization effect, the ultraviolet lamp tube in the current technology often adopts a naked installation method. That is, the ultraviolet lamp tube is arranged to face the interior of the container without obstruction. Due to the harsh environment within the container, the operating condition of the ultraviolet lamp tube is adversely affected directly, so that its service life span is also greatly shortened, the cost of use is high, and it is difficult to promote. SUMMARY OF THE PRESENT INVENTION In view of the shortcomings of the current technology, an objective of the invention is to provide a sterilization and deodorization waste container having dual-wave band ultraviolet lamp tube that avoids sterilization dead angle, enhances the sterilization effect, improves the operating environment of the ultraviolet lamp, improves service life span thereof, and reduces the cost of use. According to the invention, the foregoing objective is attained by: a sterilization and deodorization waste container having dual-wave band ultraviolet lamp tube, which includes a container body, a container lid and a control circuit, wherein one or more structural characteristic in further including an isolation chamber installed on an inner side of the container lid and a dual-wave band ultraviolet lamp tube arranged in the isolation chamber, the dual-wave band ultraviolet lamp tube being a lamp tube capable of simultaneously generating a direct sterilization ultraviolet light wave and an ozone sterilization ultraviolet light wave, the isolation chamber comprising a reflector housing and a transparent quartz glass, an opening of the reflector housing facing an inner cavity of the container body, shape and size of the transparent quartz glass fitting and matching to an opening surface of the reflector housing and being covered and connected to the opening of the reflector housing through a sealing silicone ring cover; a control input terminal of a driving circuit of the dual-wave band ultraviolet lamp tube being connected to a driving control terminal of the control circuit by a control switch. Accordingly, the invention includes the following distinctive features: 1) By means of the isolation chamber provided to isolate with outside air, the dual-wave band ultraviolet lamp tube is sealingly contained between the reflector housing and the sealedly connected transparent quartz glass. Therefore, the glass surface may merely be wiped while it is dirty and the harsh environment in the waste container is prevented to affect the ultraviolet lamp tube in the isolation chamber, that optimizes the operating environment of the ultraviolet lamp tube, improves the service life span thereof and reduces the cost of use.2) The transparent quartz glass is capable of enhancing a light transmittance of the ultraviolet light. The reflector housing can reflect most of the other ultraviolet light waves in the isolation chamber to penetrate through the transparent quartz glass into the container body, that greatly increases the intensity and number of effective light waves, and solves the conventional problems of light transmission and irradiation of the ultraviolet lamp tube.3) The dual-wave band ultraviolet lamp tube provides double sterilizations, direct sterilization and ozone sterilization, wherein the ultraviolet light wave for direct sterilization has high photon energy to penetrate the cell membrane and nucleus of microorganisms, destroy the molecular bonds of their DNA, and kill them by making them lose replication abil
