The third nozzle 161 may be disposed on the inner circumferential surface of the second housing 120. The third nozzle 161 may suck gas in the internal space by the third pump 162 which is a suction pump. Since the third nozzle 161 is disposed under the quarantine device 100, the gas sterilized from the top may be finally discharged to the outside. In detail, the gas injected from the first nozzle 143 collides with the object and moves downward. Since the gas injected from the second nozzle 151 is also injected downward, the gas eventually collects on the bottom of the quarantine device 100. The third nozzle 161 may suck in the gas concentrated below and quickly discharge it to the outside.

The quarantine device 100 may include a detection sensor 181. The detection sensor 181 may detect whether an object has entered the quarantine device 100.

The quarantine apparatus 100 may include a storage unit 180 storing a program for processing or controlling the control unit 170 and/or various data for operation of the program. The storage unit 180 may store a plurality of application programs (application programs or applications) driven by the quarantine device, data for the operation of the quarantine device, and instructions. At least some of these application programs may be downloaded from an external server and/or a cloud through wireless communication. In addition, at least some of these application programs may exist on the quarantine device from the time of shipment for basic functions of the quarantine device 100. The application program may be stored in a storage medium and driven by the control unit 170 to perform an operation (or function) of the quarantine device 100.

The storage unit 180 may include a DB that stores data on an object. The information stored in the DB may be input by the scanner 146 or the interface unit 147, but is not limited thereto, and may be transmitted through an external server, a cloud, and/or an external terminal.

To this end, the control unit 170 may further include a communication unit (not shown) to transmit and receive data, and the communication unit includes a Bluetooth communication unit, a Bluetooth Low Energy (BLE) communication unit, a near field communication unit, and a WLAN (Wi-Fi) communication unit, Zigbee communication unit, infrared (IrDA, infrared Data Association) communication unit, WFD (Wi-Fi Direct) communication unit, UWB (ultra wideband) communication unit, short-range communication unit such as Ant+ communication unit, mobile communication network.

In this case, the controller 170 may intensively sterilize the object by using information on the object stored in the storage unit 180 or information on the object obtained from the scanner 146.

For example, in a portion of an object that needs intensive sterilization or sterilization, the first driving unit 145 lowers or stops the driving speed and increases the injection amount of the first nozzle 143. In addition, the irradiation time or the irradiation amount of the lamp 142 can be adjusted.

Parts that require intensive sterilization or sterilization can be programmed according to user selection. For example, when a pollutant source is touched with a hand, the position of the object's hand is recognized from information acquired from the scanner 146 or information loaded from the storage unit 180, and the sterilization unit ( 140) can be driven.

In addition, based on the shape information obtained from the scanner 146, a strong airflow may be formed in a portion with severe curvature. Since it is difficult to remove contaminants from the folded part of the object, it is necessary to inject strong gas or inject gas for a long time. Based on the shape information obtained from the scanner 146, the control unit 170 moves the sterilization unit 140 to an area with a high degree of curvature, and controls the first nozzle 143 to inject the gas strong and for a long time. can do. Thus, even if the contaminant is located in a part where it is difficult to remove, the contaminant can be precisely removed from the object.

The controller 170 may control the driving of the second nozzle 151. If it is necessary to spray high-pressure air or chemical liquid from the top of the object downward, the control unit 170 generates a driving signal of the second nozzle 151, and the high-pressure air or chemical liquid from the second nozzle 151 toward the object Can be sprayed.

The control unit 170 may control the driving of the suction unit 160 to discharge internal foreign substances or gas to the outside. When the third nozzle 161 and the third pump 162 are driven, foreign substances or dust separated from the object may be discharged to the outside. In addition, gas sprayed from the first nozzle 143 or the second nozzle 151 may be sucked again from the third nozzle 161 and discharged to the outside.

The cover member 190 is installed to cover the outside of the quarantine device 100 and may shield the inner space of the quarantine device 100. For example, the cover member 190 is formed of a transparent material so that an object inside can be identified from the outside.

In the quarantine apparatus 100 according to the present invention, the sterilization unit 140 moving in the height direction of the object may quarantine the object in all directions. The sterilization unit 140 may move in the height direction according to the body information of the object, and may sterilize the object by irradiating light from the lamp 142 disposed on the inner circumferential surface of the sterilization unit 140. In addition, the object may be sterilized by spraying a gas or a chemical solution from the first nozzle 143 disposed on the inner circumferential surface of the sterilization unit 140.

The quarantine device 100 recognizes the shape information of the object with a scanner, or specifies a portion from which contaminants are not easily removed, based on the shape information of the object stored in the storage unit 180, and strongly applies gas to the specified area. The sterilization effect can be enhanced by spraying, spraying gas for a long time, or irradiating light for a long time.

FIG. 4 is a view showing a part of a quarantine device according to another embodiment of the present invention, and FIG. 5 is a diagram illustrating a sterilization unit 220 of the quarantine device of FIG. 4.

Referring to FIG. 4, in the quarantine device, a sterilization unit 220 is installed on the frame F, and the sterilization function may be performed while moving in the circumferential direction R at the same time as the height direction L. The sterilization unit 220 includes a base body 221 and a rotation body 222, and may be inserted so that the rotation body 222 passes through the base body 221.

The base body 221 is inserted into the frame F and may move along the frame F in the longitudinal direction. The base body 221 is installed to correspond to each frame (F). For example, if there are four frames F, four base bodies 221 may be mounted on each frame F.

The first driving unit 225 disposed inside the base body 221 is meshed with the first gear tooth FT1 of the frame F, and may move linearly along the frame F. The base body 221 and the first driving unit 225 may be driven in a rack-and-pinion structure.

The rotating body 222 may be inserted into the through hole 221A of the base body 221. The rotating body 222 may have an approximately O-ring shape, and may be inserted into the through hole 221A of the plurality of base bodies 221 and rotated. The rotating body 222 may orbit around the center of the quarantine device.

In detail, a second gear tooth FT2 is disposed on one side of the rotating body 222, and the rotating body 222 may rotate by driving the second driving unit 226. That is, the rotating body 222 and the second driving unit 226 also have a rack-and-pinion structure, and the rotating body 222 may rotate by driving the second driving unit 226.

The control unit may rotate the rotating body 222 in the circumferential direction (R). When the second driving unit 226 is driven, the rotating body 222 may revolve while passing through the base body 221.

When the rotating body 222 rotates, the gas injected from the first nozzle 222B may form a strong airflow. The gas discharged from the first nozzle 222B forms a turbulent flow in the internal space, and the turbulence can generate strong vibrations on the surface of the object, and the chemical liquid can be sprayed evenly. Accordingly, with the rotation of the rotating body 222, the gas injected from the first nozzle 222B can effectively sterilize the object.

When the rotating body 222 is rotated, light such as ultraviolet rays irradiated to the object is amplified to each other, thereby improving the sterilization effect. In addition, since the rotating body 222 rotates, even if a small number of lamps 222A are installed, the object can be irradiated with light from all directions.

The quarantine device according to the present invention moves in the height direction of the object and rotates in the circumferential direction at the same time so that the sterilization unit 220 can quarantine the object in all directions. The sterilization unit 220 may move in the height direction according to the body information of the object, and may sterilize the object by spraying gas or irradiating light while orbiting the object.
