In one embodiment, the detecting control element is selected from a group consisting of Hall element, position limiting switch and an angle sensor.
In one embodiment, the detecting control element is a Hall element and the control driving element is a magnet.
In one embodiment, the control driving element is provided under the container lid and the detecting control element is provided in the waste container where the detecting control element is able to detect a distant between the detecting control element and the control driving element to determine whether the contain lid is in a close state or open state with respect to the container body.
In one embodiment, the container lid comprises a ring shape shell arranged to be mounted on top of the container body and a cover panel pivotally connected to the ring shape shell for closing a lid opening of the ring shape shell and the container opening of the container body, wherein the control circuit comprises two pairs of detecting control element and control driving element, wherein the two detecting control elements are installed on the ring shape shell and the two control driving elements are installed on the container body and the cover panel respectively, such that when one of the detecting control elements leaves the corresponding control driving element while either the cover panel or the ring shape shell is opened with respect to the container body, the control circuit controls the dual-wave band ultraviolet lamp tube to turn off to stop generating the ultraviolets, and that when both the ring shape shell and the cover panel are closed in place with respect to the container body, the detecting control elements detect an approaching of the corresponding control driving element and the control circuit controls the dual-wave band ultraviolet lamp tube to turn on to generate the ultraviolets.
In accordance with another aspect of the invention, the present invention provides a sterilization and deodorization method of a waste container, comprising steps of:
In one embodiment, in the step (b), the inner cavity of the container body is accessible to outside when the container lid is opened with respect to the container body.
In one embodiment, in the step (b), the inner cavity of the container is accessible to outside when the ring shape shell is separated from the container body.
Accordingly, the invention includes the following distinctive features:
In particular, the invention can further be embodied as follows:
The reflector housing is either a plastic electroplated member, or a resin shell body with a reflective film formed on inner side surfaces thereof, or a stainless steel made metal member with reflective arrangement on inner side surfaces thereof.
The reflector housing is preferred to be made of materials that are not easy to age, not easy to be corroded and oxidized, to avoid ozone corrosion and improve the reflection effect of light waves.
The ultraviolet light wave for direct sterilization is 240-280 nm ultraviolet light wave, preferably an ultraviolet light wave with a wavelength of 254 nm for direct sterilization.
The ultraviolet light wave for direct sterilization is also known as short-wave sterilization ultraviolet (UVC). The 253.7-254 nm wavelength ultraviolet light has the strongest photon energy and the best sterilization effect.
The ultraviolet light wave for ozone sterilization is 165-200 nm ultraviolet light wave, preferably an ultraviolet light wave with a wavelength of 185 nm for ozone sterilization.
The ultraviolet light wave (part of the UVD light wave) for ozone sterilization irradiated in the air can turn O2 (oxygen) in the air into O3 (ozone), wherein the 185 nm ozone sterilization ultraviolet light wave is the band with better effect.
The sealing silicone ring is a sealing ring having a cross-sectional inverted U-shape, such that a peripheral edge portion of the transparent quartz glass is positioned in an inner cavity of the U-shaped sealing ring, whereby the peripheral edge portion of the transparent quartz glass is completely covered in the sealing silicone ring.
The configuration of completely covering the peripheral edge of the transparent quartz glass can reduce damage caused by vibrations of the transparent quartz glass due to the vibration of the isolation chamber installed below the container lid while being flipped up and down frequently, so as to ensure the reliability of the structure. In addition, silicone can also prevent aging caused by ultraviolet radiation.
The control switch, which is either a Hall sensor, or an angle sensor, or a position limiting switch, comprises a control driving element and a detecting control element arranged in a separable manner, the control driving element being connected to the dual-wave band ultraviolet lamp tube and the control circuit.
For example, the control driving element of the angle sensor can be installed on a main rotating shaft of the container lid. When the container lid (or cover panel while the container lid is composed of a cover panel and a ring shape shell) opens at a certain angle (that is, when the container lid or cover panel is flipped up to open), the control circuit cuts off a power supply to the ultraviolet lamp tube while receiving a signal of the angle sensor and turns it off. When the container lid (or cover panel) is flipped down to close to a predetermined angle (when the container lid or cover panel is fully closed), the ultraviolet lamp tube is controlled to turn on for sterilization. For example, while the Hall sensor includes a Hall element as the control driving element and a magnet as the detecting control element, the ultraviolet lamp tube is turned off when the magnet leaves the detection range of the Hall element (i.e. when the container lid or cover panel is flipped up to open), and the ultraviolet lamp tube is turned on when the magnet enters the detection range of the Hall element (when the container lid or cover panel is flipped down to close). Accordingly, when the container lid or cover panel is opened, the control switch sends a signal and the control circuit controls the dual-wave band ultraviolet lamp tube to turn off to avoid ultraviolet from hurting human skin and eyes, and when the container lid or cover is closed, the control switch sends a signal to make the control circuit to timely turn on the ultraviolet lamp tube to sterilize the interior of the contain body in time.
One side of the container lid is pivotally connected with the container body, and a case is arranged at a hinging side of the container lid for receiving the control circuit. The case has a cavity provided therein and the insolation chamber is provided in the cavity. The control driving element and the detecting control element of the control switch are installed on the container lid and the container body respectively.
When the container lid and the container body are embodied as an inseparable connection structure, the isolation chamber is being flipped up and down with the container lid, so that the control switch is preferred to be installed on a side of the container lid or an open edge thereof.
The container lid comprises a ring shape shell and a cover panel. A side edge of the cover panel is hinged with the ring shape shell. The ring shape shell is sleeved to the container body, wherein a control circuit is installed in an inner cavity of the ring shall shell and the isolation chamber is arranged in a cavity provided in the ring shape shell; The control switch includes two sets, the control driving element and the detecting control element of one of the two sets are installed on the ring shape shell and the container body respectively, and the control driving element and the detecting control element of another set are installed on the cover panel and the ring shape shell respectively.
In normal use, the control switch can be triggered by flipping the cover panel up or down. When it is necessary to detach the ring shape shell from the container body, the control switch can also be triggered, so as to effectively avoid harmful to the human body caused by ultraviolet leakage.
In view of above, the invention provides a sterilization and deodorization waste container with dual-wave band ultraviolet lamp tube, which utilizes an isolation chamber with the reflector housing and the transparent quartz glass to install the dual-wave band ultraviolet lamp tube, that effectively improves the operating environment of the ultraviolet lamp tube while avoiding influence on the internal circuit and mechanical components outside the isolation chamber, improves the service life span and reduces the cost of use. The drawbacks of light transmission and irradiation of ultraviolet lamp tube are resolved. The double ultraviolet sterilizations can substantially and effectively disinfect and sterilize the waste container that greatly improves the sterilization effect.
Still further objects and advantages will become apparent from a consideration of the ensuing description and drawings.

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.
Referring to
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 refer to
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 a container opening 20 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 a light-transmitting window 30 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 O2 (oxygen) in the air into O3 (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.
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.
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.
The parts not described in the first embodiment are the same as the conventional art.
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
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.
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-band ultraviolet lamp tube 33 to turn on and operate, or otherwise, the dual-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.
The parts not described in the second embodiment are the same as the conventional art.
