The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

An embodiment of the present invention will be described in detail below with reference to fig. 1 to 3, which include:

the blanket comprises a blanket body 1, wherein an ultraviolet light source 2 and a photosensitive assembly 3 are arranged on a first side surface of the blanket body 1, and the ultraviolet light source 2 and the photosensitive assembly 3 are both connected with a power supply controller 4; the blanket body 1 is also provided with an electric circuit, and the power supply controller 4 is respectively connected with the ultraviolet light source 2 and the photosensitive component 3 through the electric circuit; the photosensitive assembly 3 is used for detecting visible light signals and sending the detected visible light signals to the power controller 4; the power controller 4 is configured to supply power to the ultraviolet light source 2, and send a stop signal to the ultraviolet light source 2 according to the received visible light signal. If the light sensing component 3 does not detect the visible light signal, the power controller 4 will supply power to the ultraviolet light source 2 to make it emit ultraviolet light.

The power controller 4 comprises a single chip microcomputer MCU and triodes Q1 and Q2; when the MCU receives a signal of the photoresistor, the output changes the high level and the low level of the Q2, so that the Q2 is switched on or off; when the Q2 is switched on, the Q1 is switched off, so that the ultraviolet light source 2 is switched off; when the Q2 is turned off, the Q1 is turned on, and the ultraviolet light source 2 has current flowing through, so that the ultraviolet light source 2 emits ultraviolet light.

The working principle of the present invention is described below with an example of disinfecting the quilt 5, which specifically is: the area of the blanket body 1 can be slightly smaller than that of the quilt 5, when the blanket body 1 needs to be disinfected, the blanket body 1 is unfolded and laid, and the first side face of the blanket body faces upwards; then cover the quilt 5 that needs the disinfection on the first side of the blanket body 1, because the quilt 5 covers on the photosensitive assembly 3 in the blanket body 1, so the utility model discloses under normal operating condition, can not detect the visible light signal in this photosensitive assembly 3, the ultraviolet light source 2 on the first side carries out the ultraviolet disinfection to the quilt 5; if the user mistakenly lifts the quilt 5 being disinfected, the photosensitive assembly 3 detects a visible light signal and transmits the visible light signal to the power controller 4, and the power controller 4 drives the ultraviolet light source 2 to stop working after receiving the visible light signal, so that the ultraviolet light is prevented from damaging the human body.

When the area of the blanket body 1 is larger than that of the article to be sterilized, the blanket body 1 can also be covered above the article to be sterilized, the first side face of the blanket body 1 faces the article to be sterilized, and the photosensitive assembly 3 on the edge of the blanket body 1 is attached to the platform for containing the article to be sterilized, so as to prevent the leakage of ultraviolet light.

In this embodiment, the blanket body 1 is provided with more than two photosensitive assemblies 3, and the photosensitive assemblies 3 are uniformly distributed on the edge of the first side surface of the blanket body 1. Specifically, the blanket body 1 may be rectangular, and the photosensitive assemblies 3 are disposed at four corners and a middle point of two long sides of the rectangle, and when any one of the photosensitive assemblies 3 detects a visible light signal, the power controller 4 stops supplying power to the ultraviolet light source 2, so that the ultraviolet light source stops emitting ultraviolet light. Therefore, the photosensitive assembly 3 can detect the visible light signal no matter the quilt 5 is opened from that direction; effectively ensuring the use safety.

In this embodiment, the photosensitive element 3 is a photo resistor; wherein the photoresistor is a resistor which is made by utilizing the photoconductive effect of a semiconductor and has a resistance value which is changed along with the intensity of incident light.

In this embodiment, the ultraviolet Light source 2 is an ultraviolet LED (Light Emitting Diode) Light bar, and more than one ultraviolet LED Light bead is disposed in the ultraviolet LED Light bar; wherein, the ultraviolet LED is an LED with the light-emitting central wavelength below 400 nm; because of its high sterilizing effect of short wavelength light, ultraviolet LEDs are often used for sterilization and deodorization of home appliances; specifically, in the embodiment, 4 ultraviolet LED lamp beads are connected in series to serve as one ultraviolet LED lamp strip, and the ultraviolet LED lamp strip is supplied with power in a constant current manner, so as to exert the maximum efficiency of the ultraviolet LED and improve the service life; the ultraviolet LED lamp bar emits ultraviolet light waves with the wavelength of 275 nm.

In this embodiment, the number of the ultraviolet LED light bars is two or more, and the adjacent ultraviolet LED light bars are parallel to each other. Wherein, the quantity of this ultraviolet LED lamp strip can carry out corresponding adjustment according to disinfection effect and blanket body 1's size.

In this embodiment, the ultraviolet LED light bars are uniformly disposed in the central region of the first side surface; making the sterilization area more uniform.

In this embodiment, the power controller 4 is connected to a commercial power, wherein the power controller 4 transforms the input commercial power to make the output voltage of the commercial power less than a safety voltage of 48V.

In this embodiment, the power controller 4 is provided with a rechargeable battery, wherein the output voltage of the rechargeable battery is less than 48V, so that the output voltage of the power controller 4 is less than the safety voltage of 48V; preferably, the rechargeable battery is a lithium battery, and in the embodiment, the ultraviolet disinfection blanket can be used in various environments by arranging the rechargeable battery in the power controller 4.

In this embodiment, a power control indicator lamp is arranged on the power controller 4, so that a user can obtain the working state of the ultraviolet light source 2.

In this embodiment, the blanket body 1 is made of PVC (Polyvinyl chloride) material, which has flexibility and safety.
