Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings attached hereto.

FIG. 1 is an exemplary view showing a knob 1000 having a sterilizing function disposed at a door according to an embodiment of the present invention.

Referring to FIG. 1, a general door handle is a place where a lot of people touch each day. When the contaminated hand touches the handle, the bacteria are transferred, and the bacteria in the handle can easily be transferred to the next contact hand. Accordingly, the handle 1000 having a sterilizing function is intended to sterilize bacteria on the handle, thereby preventing the bacterial growth and diffusion.

The handle 1000 is formed with a sterilizing lamp 110 formed on a portion that a user grasps to open a door. The handle 1000 is preferably formed in a cylindrical shape so that it is not inconvenient for the user to grip, and any shape can be used as long as it can serve as a handle.

FIG. 2 is a view showing a handle 1000 having a sterilizing function according to an embodiment of the present invention, and FIG. 3 is an exploded view of a handle 1000 according to an embodiment of the present invention.

2 to 3, the handle 1000 having a sterilizing function may include an ultraviolet radiation member 100, a fixing member 200, and a radiation limiting member 300.

The ultraviolet ray emitting member 100 may emit ultraviolet rays toward the outside. The ultraviolet ray emitting member 100 may be fixed to the door by the fixing member 200.

According to an embodiment of the present invention, the fixing member 200 may be disposed at one end and the other end of the ultraviolet ray emitting member 100, and the fixing member 200 may be disposed in the middle, One side of the member 100 may be fixed to the fixing member 200.

The fixing member 200 may have a space in which at least one side of the fixing member 200 is opened to accommodate the ultraviolet radiation member 100. In addition, the fixing member 200 may include a battery for supplying power. In addition, a battery disposed inside the fixing member 200 may be connected to an external power source outside the fixing member 200. Any arrangement may be used as long as the fixing member 200 and the ultraviolet ray emitting member 100 are combined to serve as a door handle.

The radiation limiting member 300 may limit the radiation range of the ultraviolet ray radiated from the ultraviolet ray radiating member 100 to a certain range. The description of the radiation limiting member 300 will be described in more detail below.

The ultraviolet ray emitting member 100 may include a sterilizing lamp 110 and a reinforcing member 120. The ultraviolet radiation member 100 may be provided in a cylindrical shape. However, it is not limited to the shape of a cylinder.

The sterilizing lamp 110 may be a lamp emitting ultraviolet rays, for example, a lamp emitting ultraviolet rays having a peak wavelength within a range of 200 nm to 380 nm. However, any light can be used as long as it has a wavelength capable of sterilizing, as described below.

Since ultraviolet rays have a large energy, ultraviolet rays are emitted to bacteria and the bacteria are destroyed, which is an excellent sterilizing light source. In the present invention, ultraviolet light emitted by the UV LED that emits ultraviolet rays is radiated to the entire knob 1000, thereby sterilizing the door knob 1000.

The reinforcing member 120 is provided to transmit ultraviolet rays and surrounds the outer surface of the sterilizing lamp 110. The reinforcing member 120 may have a higher strength than the sterilizing lamp 110. For example, it may be a metal in the form of a net or a net, a transparent reinforced plastic that can transmit ultraviolet rays, and the like, but is not limited thereto. Any material or shape capable of transmitting ultraviolet rays and having a higher strength than the sterilizing lamp 110 can be used.

Since the general sterilizing lamp 110 has a relatively small strength for use as a grip of the handle, if the user grasps the sterilizing lamp 110, the sterilizing lamp may be damaged. Therefore, the reinforcing member 120 having a higher strength than the sterilizing lamp 110 protects the sterilizing lamp 110 by wrapping the outer surface of the sterilizing lamp 110.

4 is an exemplary view showing a radiation limiting member according to an embodiment of the present invention.

For example, the radiation limiting member 300 may be stacked in the form of a tower. The number of the radiation limiting members 300 may be increased according to the size or length of the ultraviolet ray emitting member 100.

For example, if the first radiation limiting member and the second radiation limiting member are disposed from the bottom, the ultraviolet radiation member 100 may be provided on the inner surface of the reflective film 310 of the second radiation limiting member, The ultraviolet rays emitted by the light source can be reflected. The reflected ultraviolet light may then be provided to the first radiation limiting member at the bottom. In this way, the sequentially stacked radiation confining members can sterilize the radiation confining member located under each radiation confining member through ultraviolet light.

4, the reflection restricting member 300 is provided so that the inner surface at one end thereof is brought into contact with the outer surface of the radiation member 100 along the circumferential direction of the radiation member 100, May be provided to be spaced apart from the outer surface of the radiating member 100 along the circumferential direction of the radiating member 100.

According to an embodiment of the present invention, a plurality of the reflective films 310 are arranged along the longitudinal direction of the ultraviolet ray emitting member 100, and further, the reflective films 310 are arranged .

The object sensing unit 210 may sense an object adjacent to the ultraviolet ray emitting member 100 and the control unit 220 may control the ultraviolet ray emitting member 100.

According to an embodiment of the present invention, the control unit 220 controls the ultraviolet ray radiating member 100 not to emit ultraviolet rays while an object is sensed by the object sensing unit 210, It is possible to control the ultraviolet radiation member 100 to emit ultraviolet light from a point in time when it is not sensed.

If the user holds the handle, the ultraviolet rays may be directly exposed to the human body when the ultraviolet rays are radiated, so that the ultraviolet rays should not be emitted while the object sensing unit 210 senses the object.

According to one embodiment of the present invention, the fixing member 200 includes a first fixing part 201 connected to one end of the ultraviolet ray radiating member 100, and a second fixing part 220 connected to the other end of the ultraviolet ray radiating member 100.

The control unit 220 may include a first fixing unit 201 connected to one end of the ultraviolet ray shielding unit 100 and a second fixing unit 220 connected to the other end of the ultraviolet ray emitting unit 100. [ The ultraviolet ray radiating member 100 senses an object between the time when the object is removed and the time when the object is detected after the object is removed, So that ultraviolet rays can be radiated outward.

For example, the control unit 220 may include a first fixing unit 201 connected to one end of the ultraviolet ray emitting member 100 and a second fixing unit 202 connected to the other end of the ultraviolet ray emitting member 100 If the time at which the object is detected is 1:20:30 and the time at which the object is removed is 1:20:40, the time of 10 seconds, which is the difference between the time at which the object was removed and the time at which the object was detected The ultraviolet ray emitting member 100 may emit ultraviolet rays toward the outside for 1 second to 20 seconds 40 seconds after the object is removed.
