The description below relates to a portable sterilization robot.

It is not only lack of exercise, stress, and frequent drinking that threaten a person's health. An unclean office environment can adversely affect health. In fact, the British Daily Mail test results show that the keyboard we use every day contains 20,000 times more bacteria than the toilet.

Researchers at CBT Nuggets, an IT-certified education company, examined the number of bacteria in the mouse trackpads, keyboards, phones, and ID cards commonly used in offices. As a result, 45,000 times more bacteria were found in the computer mouse than in the toilet handle.

On the office keyboard, 3543,000 bacteria were detected per square inch. This is 20,000 times the number of 172 inhabitants on the toilet cover. The mouse was breeding 1.37 million bacteria, 45,000 times higher than the toilet handle (30 per square inch), and the phone had 1.6 million bacteria per square inch.

The moving body 121 forms the outer shape of the moving unit 12 and may include a mounting portion 1211 and a plurality of leg portions 1212 extending below the mounting portion 1211.

The mounting portion 1211 is a portion for mounting the sterilizing unit 11 and can support the sterilizing unit 11. A through portion 125 for passing ultraviolet light emitted from the sterilization unit 11 may be formed in the center of the mounting portion 1211.

The sterilization space 122 is for sterilizing an object located therein by using ultraviolet rays emitted from the sterilization part 112 in communication with the through part 125 and may be formed between the plurality of leg parts 1212. .

The second connection part 123 is electrically and / or physically connected to the first connection part 113 so that the sterilizing unit 11 and the mobile unit 12 can be electrically and / or physically connected to each other. For example, the second connection portion 123 may be an elastic terminal contacting the first connection portion 113 or a projection terminal shaped to fit the first connection portion 113.

For example, the control unit 119 of the sterilization unit 11 can control the driving unit 126 of the mobile unit 12 through the first connection unit 113 and the second connection unit 123. For example, information about the mobile unit 12, such as the operating state of the driving unit 126 of the mobile unit 12 or information detected by the fall detection unit 128, also includes the second connection unit 123 and the first connection unit ( 113), it may be transmitted to the control unit 119 of the sterilizing unit (11). For example, the power supply unit 115 of the sterilization unit 11 can supply power to the driving unit 126 of the mobile unit 12 through the first connection unit 113 and the second connection unit 123.

The second detachable portion 124 may be physically coupled or separated from the first detachable portion 114. For example, the second detachable portion 124 may have a protrusion shape that matches the first detachable portion 114.

The driving unit 126 is rotatably attached to one side of the moving body 121, and can move the moving body 121 and the sterilizing unit 11 connected thereto with respect to the ground. For example, the driving unit 126 may have a structure capable of moving the portable sterilizing robot 1 in various directions. For example, the driving unit 126 may include a main wheel 1261 and an auxiliary wheel 1262.

The main wheel 1261 is rotatably installed with one rotational degree of freedom relative to the moving body 121, and can move the moving body 121 along one direction (D, see FIG. 1) with respect to the ground.

Meanwhile, the sterilization space 122 may have a shape in communication with the outside in one direction D. In other words, the moving body 121 has a cross section of a 'c' shape opened toward the ground, and the main wheel 1261 can be rotatably installed on an axis perpendicular to both sides of the moving body 121. . According to such a structure, when the main wheel 1261 rotates, the portable sterilizing robot 1 moves along one direction D, and is located in the sterilization space 122 between the plurality of leg portions 1212. The subject can be sterilized.

The auxiliary wheel 1262 may be installed at the rim of the main wheel 1261 so as to be rotatable with one rotational degree of freedom with respect to the main wheel 1261. According to such a structure, by rotating the auxiliary wheel 1262, the moving body 121 in the other direction crossing one direction (D) with respect to the ground (for example, a direction perpendicular to one direction (D)) It is possible to move. For example, a plurality of auxiliary wheels 1262 (for example, six as shown in FIG. 1) may be spaced apart along the rim direction of the main wheel 1261.

The support 127 is for supporting the moving body 121 with respect to the ground

The fall detection unit 128 can detect whether or not a step portion exists in the driving direction of the portable sterilization robot 1. The operating state of the driving unit 126 may be changed according to the information detected by the fall detection unit 128.

For example, when the fall detection unit 128 detects that a step portion exists in the driving direction of the portable sterilization robot 1, the control unit 119 receives the sensed information and stops the operation of the driving unit 126 Or, by rotating the driving unit 126 in the opposite direction, it is possible to prevent the portable sterilizing robot 1 from falling below the step.

As another example, at least a part of the fall detection unit 128 is located on a line for supplying power from the power unit 115 to the driving unit 126, and detecting a step portion serves as a switch that cuts off the power supply line at the same time. You can do it. According to such a structure, it is possible to prevent the portable sterilizing robot 1 from moving toward the step by quickly turning off the power of the driving unit 126 without having to receive a command through the control unit 119.

For example, the fall detection unit 128 may include a reed switch, an infrared sensor, and / or a hall sensor. When the fall detection unit 128 is an infrared sensor and / or a hall sensor, a step portion can be detected by applying a method well known to a person skilled in the art, and a detailed description thereof will be omitted. Meanwhile, a case where the fall detection unit 128 is a reed switch will be described later with reference to FIG. 6 and the like.

5 is a view showing the configuration of a support unit and a fall detection unit according to an embodiment, and FIG. 6 is a view showing a process of a fall detection unit according to an embodiment.

5 and 6, the support part 127 is provided on the support rod 1271 extending downwardly of the leg part 1212 and the support rod 1271, and the portable sterilizing robot 1 smooths the ground. It may include a support wheel (1272) for supporting to drive. For example, the support rod 1271 may be installed to be movable in the vertical direction with respect to the leg portion 1212.

The support 127 may be located outside the center of gravity G of the portable sterilization robot 1. For example, the support 127 can be located at the corner of the mobile unit 12. According to such a structure, in the process of the portable sterilizing robot 1 running toward the stepped portion, before the center of gravity G of the portable sterilizing robot 1 deviates from the driving surface, the support part 127 first travels And is exposed as a stepped portion. Therefore, before the portable sterilizing robot 1 deviates from the driving surface and falls to the stepped portion, the stepped portion can be detected through the fall detection unit 128, which will be described later, and the operating state of the driving unit 126 can be changed.

The fall detection unit 128 is connected to a support rod 1271 of the support unit 127, a switch box 1281 provided with a reed switch R, and a magnet 1282 installed in the moving body 121, An elastic body 1283 may be included.

The elastic body 1283 may be disposed between the switch box 1281 and the magnet 1282. The elastic body 1283 may provide elastic force in a direction in which the switch box 1281 and the magnet 1282 are separated from each other. According to this structure, the distance between the reed switch (R) and the magnet (1282) can be changed according to the size of the vertical drag transmitted to the support unit (127), while the portable sterilizing robot (1) is placed on the ground. have.

The pair of lead pieces of the reed switch R is an initial state opened as shown in FIG. 6, and has a state in which the electrical flows at both ends of the reed switch R are blocked (hereinafter, a blocked state). On the other hand, when the reed switch R approaches the magnet 1282 by the vertical drag transmitted to the support part 127, the pair of reed pieces are mutually attracted by the magnetic force to connect the electrical flow (hereinafter, connection). state). As described above, when the reed switch R is in a blocked state, the vertical drag is sufficiently low, and it can be seen that the support portion 127 corresponding to the reed switch R is exposed as a stepped portion. Conversely, when the reed switch R is in a connected state, it can be seen that the vertical drag is sufficiently high that the support part 127 corresponding to the reed switch R is located on the driving surface.

For example, the control unit 119 may control the operation of the driving unit 126 based on the signal received from the reed switch R. As another example, by connecting both ends of the reed switch (R) in the middle of the line for supplying power from the power supply 115 to the driving unit 126, when the reed switch (R) is in a blocked state (that is, the support portion corresponding thereto) When 127 is exposed as a stepped portion), power may not be supplied to the driving unit 126.

Hereinafter, various operation modes of the sterilization unit 112 will be described. The operation mode of the sterilization unit 112 may include, for example, ① desk sterilization mode, ② keyboard sterilization mode, ③ fixed sterilization mode, and ④ user setting mode. Each mode may have different driving times.

In the case of mode ①, the portable sterilizing robot 1 is moved forward using (i) the main wheel 1261, and then (ii) the side is moved using the auxiliary wheel 1262, and (iii) the main wheel. The portable sterilizing robot 1 is moved through the method using (1261) to move backward, (iv) to the side using the auxiliary wheel 1262, and repeating steps (i) to (iv) again. While moving in a zigzag form, it is possible to sterilize a wide surface such as a desk. On the other hand, if a stepped portion (see FIG. 5) is detected in the fall detection unit 128 in this process, it is possible to perform the next step. On the other hand, by using the auxiliary wheel 1262, the distance to the side can be set, for example, to the width in the left-right direction of the sterilization space 122, so that the sterilization regions do not overlap, so that there are no missing parts.

In the case of mode ②, the main wheel 1261 may be rotated to sterilize the portable sterilizing robot 1 by moving a predetermined distance (for example, the length of a conventional keyboard).

In the case of mode ③, the driving unit 126 is not operated, and for example, a small product such as a mouse, a smart phone, or a writing instrument that can be sufficiently disposed in the sterilization space 122 can be sterilized.

In the case of mode ④, the user can arbitrarily designate a moving distance of the main wheel 1262 and / or a driving time of the sterilizing unit 112.

Although the embodiments have been described by the limited drawings as described above, a person skilled in the art can make various modifications and variations from the above description. For example, the described techniques may be performed in a different order than the described method, and / or components such as the structure, device, etc. described may be combined or combined in a different form from the described method, or may be applied to other components or equivalents. Even if replaced or substituted by, appropriate results can be achieved.
