Description

Portable purification device

This invention relates to a purification apparatus, and more particularly to a portable purification apparatus.

In daily life, drinking water is an indispensable necessity for human body to maintain physical function. However, when the drinking water is in contact with the air for a period of time, the bacteria in the drinking water will begin to proliferate. Therefore, when the user drinks drinking water with a large amount of bacteria, it is easy to have physical discomfort.

A known method for purifying drinking water is to add an ultraviolet light source to the cup lid or the bottle cap. When the lid or the cap covers the water bottle or the water cup, the ultraviolet light source emits ultraviolet light to the drinking water in the water bottle or the water cup for sterilization. However, when the lid or cap is not covered by a water bottle or a water cup, ultraviolet light from the ultraviolet light source may illuminate the human body and cause injury. In addition, the lid or cap provided with an ultraviolet light source is only suitable for water bottles or cups having corresponding sizes, and is not suitable for water bottles or cups having various sizes.

The invention provides a portable purifying device capable of avoiding ultraviolet light emitted from an ultraviolet light source from being irradiated to a human body.

The present invention provides a portable purification device suitable for containers having various sizes.

The portable purification device of the present invention comprises a container, at least one cover, a sensing component and an ultraviolet light source. The container has a receiving space in which the receiving space is adapted to contain a liquid. The cover is adapted to be coupled to the container to cover the receiving space. The sensing component is disposed on the cover, wherein the sensing component is adapted to sense a state of use of the cover. The ultraviolet light source is disposed in the cover body and is adapted to emit an ultraviolet light to the outside of the cover body, wherein the ultraviolet light source is turned on or off according to the use state of the cover body.

The portable purification device of the present invention comprises a cover body, an ultraviolet light source and a support structure. The cover is adapted to be coupled to a container to cover an accommodation space of the container, the accommodation space being adapted to receive a liquid. The ultraviolet light source is disposed in the cover body and is adapted to emit an ultraviolet light to the outside of the cover. The support structure is coupled to the cover and adapted to bear against the top end of the container to support the cover above the container.

Based on the above, in the portable purifying apparatus of the present invention, the cover body is provided with a sensing component for sensing whether the cover body covers the container. When the sensing component senses that the cover covers the container, the ultraviolet light source emits ultraviolet light to sterilize the liquid in the container. Conversely, when the sensing component senses that the cover does not cover the container, the ultraviolet light source does not emit ultraviolet light to prevent ultraviolet light emitted from the ultraviolet light source from being irradiated to the human body. In addition, in the portable purifying device of the present invention, the cover body is provided with a supporting structure, so even if the size of the container and the cover body are not matched, the cover body can be supported by the supporting structure above the container, so that the cover body is suitable for various types. Different sized containers.

1A is a schematic view of a portable purifying apparatus according to an embodiment of the present invention. FIG. 1B illustrates the cover of FIG. 1A not covering the container. Referring to FIG. 1A and FIG. 1B , the portable purification device 100 of the present embodiment includes a container 110 , a cover 120 , a sensing component 130 , and an ultraviolet light source 140 . The container 110 is, for example, a water bottle or a water cup and has a receiving space S1 adapted to contain a liquid, such as drinking water. The cover 120 is adapted to be coupled to the container 110 to cover the accommodation space S1.

The sensing component 130 is disposed on the cover 120 and is adapted to sense the state of use of the cover 120 , that is, whether the cover 120 covers the container 110 . The ultraviolet light source 140 is, for example, a far ultraviolet (UVC) source disposed in the cover 120 and adapted to emit ultraviolet light to the outside of the cover 120. The ultraviolet light source 140 is turned on or off according to the use state of the cover 120. Specifically, when the sensing component 130 senses that the cover 120 covers the container 110 as shown in FIG. 1A, the ultraviolet light source 140 emits ultraviolet light to sterilize the liquid in the container 110. On the contrary, when the sensing component 130 senses that the cover 120 does not cover the container 110 as shown in FIG. 1B, the ultraviolet light source 140 does not emit ultraviolet light to prevent the ultraviolet light emitted from the ultraviolet light source 140 from being irradiated to the human body.

In the present embodiment, the material of the inner wall of the container 110 is, for example, stainless steel having a good reflectance to enhance the transfer efficiency of ultraviolet light in the container 110. Further, the ultraviolet light source 140 of the present embodiment is, for example, a light-emitting diode light source and has high directivity, and can efficiently irradiate ultraviolet light directly to the liquid in the container 110.

When the cover 120 covers the container 110 as shown in FIG. 2A and the intensity of the light entering the cover 120 from the outside of the cover 120 is less than a threshold, the control unit 150 determines that the use state of the cover 120 is the cover state and controls the ultraviolet. Light source 140 is turned on. On the contrary, when the cover 120 is separated from the container 110 as shown in FIG. 2B such that the intensity of the light entering the cover 120 from the outside of the cover 120 (ie, the light of the external environment) is greater than or equal to the threshold value, the control unit 150 determines The use state of the cover 120 is a non-coverage state and the ultraviolet light source 140 is controlled to be turned off. The present invention does not limit the size of the threshold value, and the threshold value can be determined according to design requirements.
