DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0038] The following description is disclosed to enable any person skilled in the art to make and use the present invention. Preferred embodiments are provided in the following description only as examples and modifications will be apparent to those skilled in the art. The general principles defined in the following description would be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention.

First Preferred Embodiment

[0039] This embodiment is a sterilization and deodorization waste container having dual-wave band ultraviolet lamp tube, while its container lid is not separable from its container body (such as foot-step waste container, foot-touch waste container, and etc., the present embodiment referring to the foot-touch waste container), the configurations of the foot touch control and the opening and closing operation of the container lid are conventional art that is not repeatedly described in the first embodiment. Please referring to FIG. 1 to FIG. 5:

[0040] A sterilization and deodorization waste container having a dual-wave band ultraviolet lamp tube includes a container lid 1, a container body 2 and a control circuit 13, the container body 2 being adapted for storing waste. The container lid 1 is pivotally connected at an opening above the container body 2, and the control circuit 2 and a lid opening and closing driving device 14 are installed to the container body 13. An isolation chamber 3 isolated from the air outside is arranged below the container lid 1. A light-transmitting widow is formed below the isolation chamber 3. Due to the harsh environment of the waste container, the dual-wave band ultraviolet lamp tube 33, having a II shaped configuration, is arranged in the air-isolated isolation chamber 3 and, since the ultraviolet light penetration ability is extremely weak, a transparent quartz glass 32 having very high light transmittance is embodied as the light-transmitting widow of the isolation chamber 3. The dual-wave band ultraviolet lamp tube 33 produces ultraviolet light waves, with 254 nm wavelength and 185 nm wavelength, irradiated into the waste container through the light-transmitting window made of the transparent quartz glass 32, so as to use the ultraviolet light waves for sterilization and deodorization. In which, the ultraviolet light wave with 254 nm wavelength (also known as short-wave sterilization ultraviolet) has a higher photon energy, that can penetrate cell membranes and nucleus of microorganisms, destroy the molecular bonds of their DNA, and make them losing replication ability or activity and die while irradiating microorganisms. Also, the irradiating of the ultraviolet light wave with 185 nm wavelength in the air can turn 02 (oxygen) in the air into O.sub.3 (ozone). Ozone, which has a strong oxidation effect, can effectively kill bacteria. The diffusion and dispersion ability of ozone fitly make up for the shortcoming of ultraviolet that only propagates along a straight line and has dead angles and corners for disinfection, such that the function of sterilization and deodorization is strengthened.

[0041] The isolation chamber 3 is comprised of a reflector housing 31, the transparent quartz glass 32 and a sealing silicone ring 321. A peripheral edge portion of the transparent quartz glass 32 is affixed with the sealing silicone ring 321 which has a U shaped cross section to protect. The dual-wave band ultraviolet lamp tube 33 is arranged in the sealed isolation chamber 31 configured by the reflector housing 31 and the transparent quartz glass 32. Since ultraviolet has a strong aging ability and ozone is very corrosive, the dual-wave band ultraviolet lamp tube 33 is enclosed in the sealed isolation chamber 3, such that, on one hand, the ultraviolet light wave avoids irradiating plastic structural components of a driving control mechanism but concentrates in positions of the waste contained in the container body and, on the other hand, the ozone generated by the ultraviolet light wave irradiation does not be dispersed into an inner space of the container lid 1, causing the control circuit and the internal structural components to be corroded and oxidized by the ozone. At the same time, the dual-wave band ultraviolet lamp tube 33 is isolated and protected from being polluted. If the light-transmitting window is soiled, it merely needs to wipe the transparent quartz glass 32 to ensure sufficient ultraviolet light irradiation. The reflector housing 31 (the reflector housing 31 may be made of materials such as electroplated plastic member, a reflective filmed or a stainless steel made metal member and other materials that are not easy to age, not easy to be corroded and oxidized, the reflector housing 31 in the present embodiment referring to an electroplated plastic member) is configured to reflect ultraviolet light waves into the waste container, which greatly increases the effective light wave intensity. The ultraviolet light waves reflected through the reflector housing 31 can only be irradiated into the waste container through the transparent quartz glass 32. The transparent quartz glass 32 is capable of transmitting most of the ultraviolet light waves with 254 nm wavelength and 185 nm wavelength, that ensures most of the ultraviolets being irradiated into the waste container for sterilization and generating ozone for sterilization and deodorization in the waste container. Since silicone has strong anti-aging ability, the sealing silicone ring 321 of the present embodiment adopts a sealing silicone with a U shaped cross-section.

[0042] The container lid 1 is configured to be inseparable from the container body 2. A control switch is installed in the container body 2 (this control switch can be a Hall element, a position limiting switch, an angle sensor, and etc., the present embodiment utilizing a Hall element, that is, the Hall element 131). A magnet 132 is installed to the container lid 1 such that when the container lid 1 is flipped up to open, the magnet 132 leaves a detection range of the Hall element 131 with the container lid 131, the control circuit 13 receives a signal sent from the Hall element 131, and the dual-wave band ultraviolet lamp tube 33 is turned off by a ultraviolet lamp tube driver circuit 34 to cease the generation of the ultraviolets to prevent causing harm to human skin and eyes. When the container lid 1 is flipped down to close in place, the Hall element 131 detects an approaching of the magnet 132 and the control circuit 13 controls the dual-wave band ultraviolet lamp tube 33 to turn on, or otherwise, the dual-wave band ultraviolet lamp tube 33 is always remained in a turn-off state.

[0043] The parts not described in the first embodiment are the same as the conventional art.

Second Preferred Embodiment

[0044] The present embodiment is a sterilization and deodorization induction waste container having dual-wave band ultraviolet lamp tube, while its container lid is no separable from its container body (such as induction waste container, the present embodiment referring to an induction waste container), the configurations of the infrared sensing component and the opening and closing operation of the container lid are conventional art that is not repeatedly described here. Referring to FIGS. 3, 4 and 6-8, a sterilization and deodorization waste container having a dual-wave band ultraviolet lamp tube includes a container lid 1, a container body 2 and a control circuit 13, the container body 2 being used to store waste. The container lid 1 includes a ring shape shell 11 (the ring shape shell 11 is comprised of a ring shape barrel head 111 and a ring shape retainer body 122) and a cover panel 12. The cover panel 12 is pivotally connected to the ring shape shell 11. The container lid 1 is placed above an opening of the container body 2. The control circuit 13 and the lid opening and closing driving device 14 are installed in a receiving cavity of the ring shape shell 11 defined after the ring shape barrel head 111 and the ring shape retainer body 112 are affixed together. An isolation chamber 33 isolated from the air outside is arranged below the container lid 1. A dual-wave band ultraviolet lamp tube 3 is installed in the isolation chamber 33. A transparent quartz glass 33 with very high light transmittance is provided below the dual-wave band ultraviolet lamp tube 33 as a light-transmitting window. The dual-wave band ultraviolet lamp tube 33 is generate ultraviolets with a254 nm wavelength and a 185 nm wavelength which irradiate into the waste container through the transparent quartz glass 32 of the light-transmitting window to process sterilization and deodorization through the ultraviolet light waves, wherein the ultraviolet light wave with 185 nm wavelength can produce ozone for sterilization and deodorization. In addition, due to the dispersion and diffusion ability of ozone, the ozone fills the interior space of the waste container that fitly makes up for the shortcoming of ultraviolet that only propagates along a straight line and has dead angles and corners for disinfection, such that the function of sterilization and deodorization is strengthened.

[0045] The configurations and material selections of the isolation chamber 3, the reflector housing 31, the transparent quartz glass 32, the sealing silicone ring 321, the dual-wave band ultraviolet lamp tube 33 and the sterilization and deodorization principle of the dual-wave band ultraviolet lamp tube 33 may refer to the description in the first preferred embodiment and are not repeatedly described in this embodiment.

[0046] The container lid 1 may be separated from the container body 2. The container lid 1 is comprised of a ring shape shell 11 and a cover panel 12. A control switch is installed on the container lid 1 (this control switch can be a Hall element, a position limiting switch, an angle sensor, and etc., this embodiment utilizing Hall elements, including a Hall element 131 and a Hall element 133). A magnet 134 is installed on the container body 134 such that, when the container lid 1 is separated from the container body 2, the magnet 134 leaves a detection range of the Hall element 133. After the Hall element 133 generates a signal, the control circuit 13 controls the dual-wave band ultraviolet lamp tube 33 to turn off to stop generating the ultraviolets to prevent causing harm to human skin and eyes. Similarly, the cover panel 12 is equipped with a magnet 132 such that, when the cover panel 12 is opened, the magnet 132 leaves the detection range of the Hall element 131. After the Hall element 131 generates a signal, the control circuit 13 controls the dual-wave band ultraviolet lamp tube 33 to turn off to stop generating the ultraviolets to prevent causing harm to human skin and eyes. When the cover panel 12 is closed in place and the container lid 1 is placed on the container body 2, that is only while these two conditions are met at the same time, the control circuit 13 controls the dual-wave band ultraviolet lamp tube 33 to turn on and operate, or otherwise, the dual-wave band ultraviolet lamp tube 33 is always remained in the turn-off state. Based on the embodiments described above, the ultraviolet lamp tube 33 can also be set with a predetermined sterilization time period.

[0047] The parts not described in the second embodiment are the same as the conventional art.

[0048] The above description is merely preferred embodiments of the invention and is not intent to limit the invention, and any modification, equivalent substitution, improvement, and etc. made within the spirit and principles of the invention should be included within the scope of the claimed invention.
