Description

Technology Field

[0001] The present invention relates to a portable shoe sterilization device using plasma, and more specifically, to a portable shoe sterilization device using plasma that is inserted into a shoe to generate airflow and sterilizes and deodorizes contaminated air inside the shoe through high-voltage plasma. Background Technology

[0002] Generally, various types of footwear, such as dress shoes, sneakers, and boots, have been developed to protect the human foot and are used by everyone. These shoes are designed with a sealed structure in parts other than the foot insert formed at the top, in order to safely protect the entire foot, including the toes, when worn and to prevent external dust or moisture from seeping into the shoe.

[0003] Consequently, the breathability of the shoes is significantly reduced, and when engaging in activities while wearing shoes with poor breathability, sweat from the feet seeps into the inside of the shoes and does not dry properly, creating an environment where various bacteria can multiply. Various bacteria and germs, such as Staphylococcus aureus, Pseudomonas aeruginosa, E. coli, and athlete's foot fungi, inhabit the inside of the shoes worn by users. If the shoes are not washed or dried frequently, there is a very high risk of athlete's foot or eczema developing. Additionally, there is a problem of severe foot odor caused by bacteria living in the humid environment inside the shoes and isovaleric acid, a substance produced by these germs.

[0004] To address these issues, Korean Patent No. 10-1200405 discloses a shoe cabinet equipped with shoe disinfection and drying functions; however, the invention has the disadvantage of poor mobility because it must be permanently installed or placed in a specific location. To resolve this mobility issue, Korean Patent No. 10-1335943 discloses a shoe sterilization device using UV LEDs; however, it has the disadvantage that shoe sterilization cannot be perfectly achieved using UV LEDs alone.

[0021] Referring to FIGS. 1 to 8, the portable shoe sterilization device (1000) using plasma according to the present invention is a device that is inserted into a shoe to sterilize the inside of the shoe, and includes a case part (100), a blower part (200), a plasma generating part (300), a power supply part (400), and a control part (500).

[0022] More specifically, a portable shoe sterilization device (1000) using plasma comprises: a case part (100) having an internal space (130), one or more intake ports (111) formed on one side and one or more exhaust ports (121) formed on the other side; a blower part (200) embedded in the internal space (130) and circulating internal and external air of the case part (100) through the intake port (111) and the exhaust port (121); a plasma generator part (300) embedded in the internal space (130) and generating plasma by high voltage to sterilize and deodorize air sucked into the internal space (130) by the blower part (200); a power supply part (400) that supplies power to one or more of the blower part (200) and the plasma generator part (300); and one or more of the blower part (200), the plasma generator part (300), and the power supply part (400) being driven It is configured to include a control unit (500) that controls.

[0023] The case portion (100) is formed to a size that can be inserted into a shoe, and an internal space (130) for accommodating parts is provided.

[0024] One or more intake ports (111) may be formed on one side of the case portion (100), and one or more exhaust ports (121) may be formed on the other side.

[0025] The case portion (100) may include a first case member (110) and a second case member (120). More specifically, the case portion (100) may be configured to include a first case member (110) having one or more of the intake ports (111) formed therein, and a second case (120) coupled to the first case member (110) having one or more of the exhaust ports (121) formed therein.

[0026] The case portion (100) may be formed in an approximately elliptical shape when viewed from the front, and in an approximately circular shape when viewed from the upper or lower side. That is, the outer surface of the case portion (100) may be formed in a gently curved shape.

[0027] The blower unit (200) is built into the internal space (130) of the case unit (100) and can circulate internal and external air of the case unit (100) through the intake port (111) and the exhaust port (121).

[0028] The blower unit (200) can be positioned adjacent to the intake port (111) of the first case member (110) to facilitate the intake of external air.

[0029] This blower unit (200) may include a blower fan (210) and a blower control member (220).

[0030] More specifically, the blower unit (200) may include a blower fan (210) that sucks in external air and supplies it to a plasma generator (300), and a blower control member (220) that is arranged parallel to the blower fan (210) in the blower direction and is equipped with one or more vents (221) and a cover (222) that covers the vents (221).

[0031] The blower control member (220) prevents air from passing through by blocking the ventilation opening (221) with a shield (222) when the blower fan (210) is not operating, and when the blower fan (210) is operating, the shield (222) is deformed by the blower air without a separate power source, thereby opening the ventilation opening (221) to allow air to pass through.

[0032] The plasma generating unit (300) is built into the internal space (130) of the case unit (100) and can generate plasma by high voltage to sterilize and deodorize the air sucked into the internal space (130) by the blower unit (200).

[0038] The switch (410) can be exposed to the outside through a hole formed in the center of the second case member (120), and the user can operate or stop the portable shoe sterilization device (1000) using plasma through the switch (410).

[0039] The battery (420) may be a primary battery such as a dry cell or a rechargeable battery such as a lithium polymer battery.

[0040] The charging port (430) is mounted on one side of the PCB board (510) and exposed to the outside through the side of the case part (100), and is electrically connected to an external power source to charge the battery (420).

[0041] The control unit (500) can control the operation of one or more of the blower unit (200), plasma generator (300), and power supply unit (400).

[0042] The control unit (500) may include a PCB board (510) and a microprocessor (not shown).

[0043] More specifically, the control unit (500) comprises a PCB substrate (510) having one or more ventilation holes (511) formed therein and a microprocessor mounted on the PCB substrate (510) to perform a set control function.

[0044] The microprocessor may include a plasma generation control unit that controls the plasma generation unit (300), an input monitoring unit that monitors the input of the switch (410), a battery monitoring unit (450) that monitors the state of the battery, and a timer management unit that performs a timer function.

[0045] Meanwhile, the internal space (130) of the case part (100) is divided into an intake space (131) and an exhaust space (132) by a PCB board (510), and a blower part (200) is connected to one side of the intake space (131) of the PCB board (510), and a plasma generating part (300) is connected to one side of the exhaust space (132) of the PCB board (510).

[0046] That is, external air sucked into the intake space (131) through the intake port (111) of the first case member (110) is supplied to the exhaust space (132) by the blower unit (200), and the air supplied to the exhaust space (132) is sterilized and deodorized by the plasma generator (300) and exhausted to the outside through the exhaust port (121) of the second case member (120).
