Description

Sterilization laundry ball

This creation relates to a laundry ball, and in particular to a sterilizing laundry ball.

The laundry ball is a washing aid for a washing machine, which can improve the washing effect on the laundry. A general laundry ball achieves the effect of cleaning dirt by rolling friction or collision with the clothes. In addition, there is a laundry ball with an ultraviolet LED inside to sterilize the clothes while washing the clothes.

However, the ultraviolet light is absorbed by the dirt in the wash water, that is, the ultraviolet light is easily attenuated in the water. Therefore, the use of ultraviolet-only laundry balls can only sterilize the local range.

Therefore, the purpose of the present invention is to provide a sterilization laundry ball with better sterilization effect.

The technical means for solving the problems of the prior art provides a sterilizing laundry ball, comprising: a casing, forming an accommodating space around the casing, the casing is permeable to light, and a photocatalyst layer is coated on the surface. An illuminating device is disposed in the accommodating space, the illuminating range of the illuminating device covers the photocatalyst layer; and a battery is disposed in the accommodating space and electrically connected to the illuminating device.

In an embodiment of the present invention, a sterilizing laundry ball is provided, and the illuminating device is an ultraviolet light illuminating device.

In an embodiment of the present invention, a sterilizing laundry ball is provided, and further includes a water inlet sensor coupled to the illuminating device for sensing whether the housing is filled with water, and the illuminating device is based on the sense of the water inlet sensor. The result is illuminated.

In an embodiment of the present invention, a sterilizing laundry ball is provided, the water inlet sensor has two metal pole pieces spaced apart, and the water inlet sensor determines whether the water is in accordance with the impedance between the two metal pole pieces. .

In an embodiment of the present invention, a sterilizing laundry ball is provided, the photocatalyst layer being applied to an outer side of the casing.

Through the technical means adopted by the sterilized laundry ball of the present invention, the photocatalyst layer is irradiated with light emitted by the illuminating device to generate a photocatalytic reaction. The generated hydroxyl radicals can be uniformly distributed in the washing water along with the water flow, and the organic matter in the water and the laundry is decomposed to have a good bactericidal effect. Further, in the embodiment using the ultraviolet light-emitting device, the ultraviolet light that does not participate in the photocatalytic reaction can be transmitted out of the casing, and the sterilization effect can be further enhanced.

Hereinafter, embodiments of the present creation will be described based on the first and second drawings. This description is not intended to limit the implementation of the present invention, but is one of the embodiments of the present invention.

As shown in FIG. 1 , a sterilizing laundry ball 100 according to the first embodiment of the present invention comprises: a casing 1 around which an accommodating space S is formed, and the casing 1 is permeable to light and coated on the surface. A photocatalyst layer 11 is disposed in the accommodating space S. The illumination range of the illuminating device 2 covers the photocatalyst layer 11; and a battery 3 is disposed in the accommodating space S and electrically connected to the illuminating device 2.

In the present embodiment, the casing 1 is composed of a detachable hemispherical shell to facilitate replacement of the battery 3 in the accommodating space S. The housing 1 is sealed after assembly so that the interior of the housing 1 is free of water, and the photocatalyst layer 11 is applied only to the outer side of the housing. In detail, the housing 1 is a transparent acrylic housing. Thereby, the light emitted by the light-emitting device 2 can be directly irradiated to the photocatalyst layer 11 from being absorbed by the water in the casing and/or the casing 1.

Among them, the casing 1 is a spherical outer casing. In other embodiments, the housing 1 may also be an outer shell of an ellipsoid, a polyhedron or the like. The surface of the casing 1 may also have various concavo-convex structures with a large surface area for coating the photocatalyst layer 11.

The photocatalyst layer 11 is applied to the outer side surface of the entire casing 1. In the present embodiment, the photocatalyst layer 11 contains titanium oxide. When titanium dioxide is irradiated with ultraviolet light, it generates a hydroxyl radical (•OH) with high oxidizing power, and the hydroxyl radical can be uniformly distributed in the washing water along with the water flow, and the organic matter in the water and the laundry is decomposed, and Good sterilization and disinfection effects.

Correspondingly, the light-emitting device 2 is an ultraviolet light-emitting device to enable the photocatalyst layer 11 to react. In addition, ultraviolet light that does not participate in the photocatalytic reaction can pass through the casing 1, and the sterilization effect can be further enhanced. In detail, the illuminating device 2 is a plurality of ultraviolet LEDs, and the directions of each other are different so that the illumination range can cover the entire photocatalyst layer 11. Of course, the present invention is not limited thereto. In other embodiments, the titanium dioxide in the photocatalyst layer 11 may be replaced with other photocatalyst materials, and the light-emitting device 2 is a device capable of emitting light of a corresponding wavelength.

As shown in Fig. 2, the sterilizing laundry ball 100a according to the second embodiment of the present invention is substantially the same as the sterilizing laundry ball 100 of the first embodiment. The main difference is that the sterilizing laundry ball 100a of the second embodiment is provided with a water inlet sensor 4 connected to the illuminating device 2 for sensing whether the housing 1 is filled with water. The light-emitting device 2 emits light when the water inlet sensor 4 senses that the casing 1 is in water to ensure that the sterilizing laundry ball 100a of the present invention can be automatically started and stopped during use, thereby saving the use of the battery 3 power. In the present embodiment, the water inlet sensor 4 has two metal pole pieces 41 spaced apart from each other, and the metal pole piece 41 is exposed outside the casing 1. The water inlet sensor 4 judges whether or not water is entered based on the impedance between the two metal pole pieces 41. In detail, when the water is introduced, the impedance between the two metal pole pieces 41 is lowered, that is, it can be judged that the casing 1 is not in the water. Of course, the water inlet sensor 4 can also be other kinds of liquid sensors or motion sensors.

In other embodiments, the housing 1 may be formed with a through hole that communicates with the accommodating space S and the outside of the housing, so that the washing water can enter the accommodating space S. The photocatalyst layer 11 can be applied to the inner side surface of the casing 1 to have a large contact area between the photocatalyst layer 11 and the wash water. The water inlet sensor can also be completely accommodated in the accommodating space S without collision.

The above description and description are only illustrative of the preferred embodiments of the present invention, and those having ordinary skill in the art may make other modifications in accordance with the scope of the patent application as defined below and the above description, but such modifications are still It is the creative spirit of this creation and is within the scope of this creation.
