Patent Description:
People living in modern times do not mind investing a lot of money, time, and effort for beauty. One example for beauty may include skin beauty. Since the skin is usually shown first for people, the people invest a lot of money in skin care.

Devices for beauty may include devices using laser, ultrasound, or plasma. In particular, there may be a recent trend that the number of devices using plasma is increasing.

Plasma is an ionized gas and may be a fourth state of a material following solid, liquid, and gas. In general, plasma may be generated based on discharge of high voltage and may be used for the purpose of treatment and shaping of an epidermal portion of the skin due to a sublimation action occurring when induced on the skin of a user. Here, the sublimation action may refer to a phase transition phenomenon in which a substance changes from a solid to a gas without going through a liquid process in chemistry.

Since plasma is generated based on discharge of high voltage, devices using plasma may be formed as a single set with a separately provided power supply source to be stably supplied with power. However, as the power supply source and the devices using the plasma are formed as a single set, the user (e.g., an operator) needs to have several sets of devices and power supply sources to perform an appropriate procedure on a human body of a customer. This forced the user to make a lot of financial investment and eventually caused a lot of cost to be charged to the customer.

For example, the switch unit may turn ON at least one electrode among the plurality of electrodes. The switch unit may turn OFF at least one electrode among the plurality of electrodes.

The plurality of transformers are configured to boost voltage transmitted from the plurality of electrodes. The plurality of transformers may be a device that varies voltage using electromagnetic induction. The transformer may be understood as a transducer that boosts the voltage.

Each of the plurality of transformers may include a first core and a second core. Each of the plurality of transformers may further include a coil configured to wind around the first core and the second core.

The first core and the second core may be formed in a bar shape. The first core and the second core may have a solid cylindrical shape or a hollow cylindrical shape.

The first core and the second core may include a ferrite core or an iron core. One end of the first core may pass through a primary coil and another end thereof may pass through a secondary coil. Voltage applied to the primary coil of the first core may be boosted in the secondary coil.

The plurality of transformers according to the present disclosure may include the first core and the second core in the bar shape, which differs from an EI-type core. Accordingly, volume may be smaller than that of the conventional transformer and may be easily provided in a limited space inside the first gripping portion <NUM>.

According to some example embodiments of the present disclosure, the number of the plurality of transformers may be less than or equal to the number of plurality of pins provided to the first operating portion <NUM>. Here, the plurality of pins may be members that induce plasma generated from the plasma generating portion to be irradiated to the skin.

Therefore, the at least one pin that receives the voltage may irradiate plasma to the human body.

For example, the switch unit may independently turn ON/OFF each of the plurality of electrodes. The switch unit may apply voltage to three transformers through three electrodes among the plurality of electrodes. The three transformers to which the voltage is applied may boost the applied voltage and may transmit the boosted voltage to three electrodes included in the plasma padder. The three electrodes of the plasma padder may transmit the voltage to the plurality of pins connected to each electrode. For clarity of description, it is assumed that a single pin is connected to each of three electrodes. As three pins receive the voltage, plasma may be irradiated to the human body. That is, the user may irradiate plasma through at least one pin among the plurality of pins provided to the first operating portion <NUM>. Therefore, if necessary, the user may irradiate plasma to a wide area using all of the plurality of pins or may irradiate plasma to a narrow area using at least one pin. Depending on example embodiments, output of plasma irradiated through at least one pin and output of plasma irradiated through the plurality of pins may differ from each other. The user may adjust the output by controlling an operation of the plurality of pins depending on necessity.

According to some example embodiments of the present disclosure, the number of the plurality of electrodes provided to the plasma padder may be less than or equal to the number of the plurality of pins. For example, if the number of the plurality of pins is nine, the number of the plurality of electrodes provided to the plasma padder may be nine or less. Meanwhile, if the number of the plurality of electrodes provided to the plasma padder is less than the number of plurality of pins, the plurality of pins may be connected to a single electrode. For example, the number of the plurality of electrodes provided to the plasma padder may be three and the number of the plurality of pins may be nine. In this case, three pins may be connected to each of three electrodes provided to the plasma padder.

According to some example embodiments of the present disclosure, the plurality of pins provided to the first operating portion <NUM> may receive only voltage without direct connection to the plasma padder. For example, the first operating portion <NUM> may include a printed circuit board (PCB) substrate for receive voltage from the plasma padder and transmitting the voltage to the plurality of pins. In this case, the plurality of pins may be connected to the PCB substrate. The PCB substrate may receive the voltage from the plasma padder or the plasma generating portion. The PCB voltage that receives the voltage may transmit the voltage to the plurality of pins.

According to some example embodiments of the present disclosure, at least some of components that constitute the plasma generating portion may be provided to the first operating portion <NUM>. For example, the plasma padder may be provided to the first operating portion <NUM>.

The second ozone removal portion may include a suction fan, an ozone filter, and a filter case. The second ozone removal portion is configured to remove ozone that is generated as plasma is irradiated to the human body.

The suction fan may suck ozone based on the input from the user.
