Detailed Description

The present invention will be further explained with reference to the drawings and examples.

The disinfection device is used for disinfecting the L-shaped door handle, the door handle is disinfected from the end part of the L-shaped door handle, and one L-shaped door handle only needs to be provided with one disinfection device.

The overall structure of the present sterilization apparatus is shown in fig. 1, and the positional relationship between the present sterilization apparatus 300 and the door handle 200 when the apparatus is assembled to the door body 100 is shown in fig. 2, wherein the door body 100 is shown only partially in fig. 2, the door handle 200 is shown in an L-shape, and the door lock is unlocked when the door handle 200 is rotated about the rotation center 210.

As shown in fig. 1, the present sterilization apparatus 300 includes a housing 1, the housing 1 is small in size and can be assembled to a door body 100 at a position opposite to an end of an L-shaped door handle 200 (as shown in fig. 2), a plurality of ultraviolet light radiation units 2 are disposed at a same side portion of the housing 1, and the plurality of ultraviolet light radiation units 2 are arranged such that the plurality of ultraviolet light radiation units 2 radiate ultraviolet light onto at least two surfaces of the L-shaped door handle 200 when the housing 1 is assembled to the door body 100 and the side portion of the housing 1 is opposite to the end of the L-shaped door handle 200 (as shown in fig. 2).

Specifically, in this embodiment, six ultraviolet radiation units 2 are designed, and by arranging the six ultraviolet radiation units 2 on the side portion of the housing 1, when the housing 1 is assembled on the door body 100 and the side portion of the housing 1 is opposite to the end portion of the L-shaped door handle 200, the plurality of ultraviolet radiation units 2 radiate ultraviolet light on five surfaces of the face portion, the back portion, the top portion, the bottom portion and the end portion of the L-shaped door handle 200, so that the sterilization effect on the L-shaped door handle 200 is better. It should be understood that only the three surfaces of the face, top and back that are in contact with the hand, which are larger and more susceptible to the transmission of pathogens, may be radiation sterilized, or when the door handle is thinner and the top area is smaller, only the two surfaces of the face and back may be radiation sterilized.

The door further includes a light blocking device, which is disposed on the door body 100 opposite to the other end (the left end in fig. 2, that is, the end near the rotation center 210) of the L-shaped door handle 200, so that the ultraviolet light radiated by the ultraviolet light radiation unit 2 can be blocked, and the children can be prevented from being accidentally injured by the radiated ultraviolet light when approaching the door handle 200.

In the present embodiment, the ultraviolet light radiation unit 2 specifically includes a plurality of light emitters 22 and a light guide 21, the light emitters 22 of the ultraviolet light radiation unit 2 are located on the same plane (as shown in fig. 3), and the light guide 21 guides the ultraviolet light radiated by the light emitters 22 to corresponding positions. That is, the light path is changed by the light guide 21, so that the ultraviolet light emitted from the light emitters 22 on the same plane can be radiated to different surfaces of the L-shaped door handle 200. This arrangement allows all of the light emitters 22 to be mounted on the same circuit board by surface mount technology, thereby providing the advantage of simple manufacture.

Referring to fig. 3, further, the light emitters 22 of a plurality of the ultraviolet light radiation units 2 are mounted on the same circuit board, which is referred to as a first circuit board 23 for convenience of description, and the light guides 21 of the plurality of ultraviolet light radiation units 2 are light guide bowls with different shapes. And the light guide bodies 21 of a plurality of ultraviolet light radiation units 2 are molded on the same substrate 24, the substrate 24 and the first circuit board 23 are combined through screws to form an optical module 20, and the optical module 20 is clamped in the shell 1 and can be detached. Thus, a plurality of the ultraviolet radiation units 2 are assembled in the housing 1 as a whole, and the maintenance is convenient.

As another embodiment, the ultraviolet light radiation unit 2 may be only composed of the light emitters 22, and the angles of the light emitters 22 are set, that is, the light emitting surfaces of the light emitters 22 of the ultraviolet light radiation units 2 face different directions, so that the ultraviolet light radiation units 2 can radiate ultraviolet light on at least two surfaces of the L-shaped door handle 200. For example, one light emitter 22 is parallel to the first circuit board 23, and the remaining light emitters 22 are installed at an inclination angle to the first circuit board 23 such that the light emitting surface faces the center line of the first circuit board 23, so that when the housing 1 is assembled to the door body 100 and the side portion of the housing 1 is opposite to the end portion of the L-shaped door handle 200 (the state shown in fig. 2), the plurality of ultraviolet light radiation units 2 can also radiate ultraviolet light on five surfaces of the face portion, the back portion, the top portion, the bottom portion and the end portion of the L-shaped door handle 200. Compared with the previous embodiment, the angle of the light-emitting body 22 needs to be individually set in the another embodiment, so that the manufacturing process is slightly complicated when the scheme is adopted.

As shown in fig. 4, further, the housing 1 includes: a base 11 for assembly with the door body 100; a housing 12 detachably fitted to the base 11; and a power supply body 6 (see fig. 5) accommodated inside the housing body 1, a plurality of the ultraviolet radiation units 2 being mounted to the housing body 12.

By the means, the shell body 12 can work only by being matched with the base 11, and the shell body 12 cannot be used when being taken away alone, so that the anti-theft function can be achieved to a certain degree. Specifically in this embodiment, first inductor 4 adopts micro-gap switch, installs in casing 12, and there is bellying 111 in the design of the face of base 11, and after casing 12 installed to base 11, bellying 111 supported and pressed micro-gap switch, and after casing 12 left base 11, micro-gap switch with bellying 111 parts, micro-gap switch's state upset, controller 9 detected this upset back, and control ultraviolet radiation unit 2 does not radiate ultraviolet light.

Further, the housing 1 further includes: a controller 9; and a second sensor 3 (see fig. 1) for detecting whether a human body approaches; the second sensor 3 is installed at the ultraviolet light radiation unit 2 and connected to the controller 9, when a human hand approaches the door handle 200, the output of the second sensor 3 changes, the controller 9 controls the ultraviolet light radiation unit 2 to stop radiating ultraviolet light after detecting the change, when the human hand leaves the door handle 200, the output of the second sensor 3 returns to an original state, and the controller 9 controls the ultraviolet light radiation unit 2 to start radiating ultraviolet light after detecting the change. Thus, the door handle 200 can be sterilized in time after use, and ultraviolet rays can be prevented from irradiating hands. The second sensor 3 is preferably an infrared sensor, a reflective photoelectric sensor, or the like.

The shell 1 further comprises a visible light radiation unit which is controlled by the controller 9 to work synchronously with the ultraviolet light radiation unit 2.
