A second transmission ring that covers the transmission ring 114a and the second reflection ring 113b, is formed transparently so that the ultraviolet rays output from the second ultraviolet light emitting diode 112d are transmitted, and faces the door handle. (114b).

In particular, the other end of the first clamp 111a and the other end of the second clamp 111b may be fastened by the fastening part 111f. That is, the fastening part 111f passes through the first fastening hole 111e provided on the other side of the second clamp 111b and the second fastening hole 111d provided on the other side of the first clamp 111a. Thus, the first clamp 111a and the second clamp 111b may be fastened.

That is, the first clamp 111a and the second clamp 111b are formed in the form of a semicircular ring so as to be fastened to the door handle 200 while surrounding the door handle 200 in the form of a rod, and One side of the first clamp 111a and the second clamp 111b are connected by the connection part 111c, and the other side of the first clamp 111a and the second clamp 111b is connected to the fastening part 111f. ) can be concluded by

Therefore, the door handle sterilization device 100 according to the present invention can be attached to and detached from the door handle 200.

Since the sterilization unit 110 can be separated into two semicircular ring-shaped components as described above, the internal components of the sterilization unit 110, for example, the light emitting unit 112 , The reflection ring 113 and the transmission ring 114 can be separated easily, and therefore, the light emitting part 112, the reflection ring 113 and the transmission ring 114 can be easily repaired. can

When the clamp 111 moves up and down or left and right along the door handle 200, the door handle 200 is moved by the ultraviolet rays output from the ultraviolet light emitting diodes 112c and 112d provided in the sterilization unit 112. can be sterilized.

Next, the first fixing part 191 is mounted on one upper side of the case and can be fixed on one upper side of the door handle, and the second fixing part 192 is mounted on one lower side of the case and can be fixed on one upper side of the door handle. It can be fixed to one side of the lower part of the handle.

By the first fixing part 191 and the second fixing part 192, the sterilization part 110 is stably mounted on the door handle 200 and can be moved along the door handle 200. .

Each of the first fixing part 191 and the second fixing part 192 may have the same shape as the clamp 111 .

That is, each of the first fixing part 191 and the second fixing part 192 may be composed of two semicircular structures, and the two structures may surround the door handle 200, , The two structures may be fastened through a fastening part, and thus, each of the first fixing part 191 and the second fixing part 192 may be fixed to the door handle 200 .

Next, the sensing unit 160 is mounted on the case and detects whether or not the user is approaching.

The sensing unit 160 may detect whether the door 300 is opened or closed or whether the door 300 is moved.

To this end, the sensing unit 160 may be composed of sensors having various shapes and functions.

Finally, the control unit 130 may drive the driving unit 120 according to the sensing information received from the sensing unit 160 .

For example, as a result of analyzing the sensing information received from the sensing unit 160, the user is not approaching in the direction of the door 300, the door 300 is not opened or closed, or the door 300 ) is not moving, the control unit 130 rotates the driving unit forward or backward, and drives the at least one UV light emitting diode so that the sterilization unit 110 moves the door handle 200. can be disinfected.

As a result of analyzing the sensing information received while the door handle 200 is disinfected by the sterilization unit 110, when it is determined that the user is approaching the door 300, the control unit 190 controls the driving unit The operation of (190) can be stopped.

In addition to the components described above, the doorknob sterilization device according to the present invention is mounted inside the case, controlled by the control unit 190, exposed to the outside of the case, and the sterilization unit 110 It may further include a display 170 that outputs information on an operating state and a communication unit that communicates with a user terminal through a network under the control of the control unit 190 .

For example, the control unit 190 determines the time at which the driving unit 190 is finally driven, the number of times the driving unit 190 is driven and disinfected during the day, whether the driving unit 190 is operating, and the like. Information may be output to the display 170 . Therefore, a manager who manages the doorknob sterilization device 100 according to the present invention can obtain various information through the display 170.

In addition, in order to transmit various information as described above to a remote manager, the doorknob sterilization device according to the present invention may include the communication unit. The communication unit may transmit various types of information as described above to various types of user terminals such as smart phones, tablet PCs, personal computers (PCs) and notebooks through wired or wireless communication networks.

8 is an exemplary diagram illustrating a method of sterilizing a door handle by the door handle sterilization device according to the present invention.

When the UV light emitting diodes 112x are provided at an angle of 60° as shown in (a) of FIG. 8, a shaded area in which UV rays do not reach the doorknob 200 may be generated. In this case, in order to achieve a sterilization effect, the drive unit 120 must be driven for a long time, and accordingly, heat generation in the light emitting unit 112 increases, and the life of the light emitting unit 112 may be shortened.

In order to prevent this, in the present invention, as shown in (b) of FIG. 8, UV light emitting diodes 112x are provided to form an angle of 30° on the inner circumferential surface of the sterilization unit 110. Accordingly, the shaded area where ultraviolet rays do not reach can be completely removed, the sterilizing power can be increased, the driving time of the driving unit 120 can be drastically shortened to more than 1/4, and the problem of invention can be reduced. there is.

That is, the plurality of UV light emitting diodes 112x may be spaced apart at 30° intervals around the central axis of the clamp and disposed on the inner circumferential surface of the sterilization unit 110 .
