The arrangement of the components is not limited to that shown in FIG. 1, and the components may be placed in any position to perform the functions they impart to the IPL sterilizing device 100.

The body 101 may be implemented in various shapes. For example, the body 101 may be formed as an overall T-shaped type. Of course, the body 101 may be implemented in various shapes, such as an I-shape or a rectangular parallelepiped type.

A handle 102 may be placed on the body 101 so that the user can pick it up when using the IPL sterilizing device 100. For example, the body 101 may include a first body part 101a on which the handle 102 is installed and a second body part 101b on which a lamp 130 for sterilization is installed. As an example, the user picks up the IPL sterilization device 100 through the handle 102, positions the second body portion 101b on which the lamp 130 is installed close to the area or object to be sterilized, and uses the lamp 130. Sterilization can be performed by outputting pulsed light through.

Components of the IPL sterilization device 100 may be disposed on the body 101. For example, a lamp 130, an output unit 160, a handle 102, etc. may be installed on the body 101. In addition, the body 101 includes components not shown in the drawing, such as the power supply unit 110, capacitor 120, circuit unit 140, sensor unit 150, and controller 180, inside or outside the body 101. can be installed in Of course, each component may be installed inside or outside the handle 102, and is not limited to the above description.

In one embodiment, the IPL sterilization device 100 may include a wheel 191 in one area of the second body portion 101b to maintain contact with the object to be sterilized and to facilitate movement. For example, the wheel 191 may be disposed in the lower portion of the second body portion 101b or in one area of the light guide unit 131.

Referring to FIG. 3(a), which is a schematic cross-sectional view of the IPL sterilization device 100, the wheel 191 disposed at the lower part of the second body portion 101b contacts the area to be sterilized and rotates by the user's force. can do. For example, the wheel 191 may be formed in a structure that prevents light output from the lamp 130 from leaking to the outside. Specifically, the wheel 191 may be formed in a structure that protrudes to a certain extent and surrounds the light guide unit 131. Here, a plurality of wheels 191 may be used to surround the light guide unit 131, or a wheel having a large area so as to surround the light guide unit 131 may be used.

The IPL sterilizing device 100 outputs pulse light of strong intensity for sterilization. If the output pulse light leaks to the outside, the user's eyes may be dazzled when using the IPL sterilizing device 100 for sterilization and may momentarily Light of strong intensity is applied to the user's eyes, which may be harmful to eye health. In one embodiment, the IPL sterilization device 100 may include a light blocking unit 190 disposed in one area of the body 101 to reduce external leakage of pulsed light output from the lamp 130. there is. For example, the light blocking portion 190 may be arranged to surround the lower portion of the body 101.

Optionally, a wheel 191 may be installed on one end of the light blocking unit 190 to facilitate movement while maintaining contact with the object to be sterilized. For example, the light blocking portion 190 is formed in a structure that can accommodate the wheel 191 (for example, a concave groove the size of the wheel 191) and prevents light from leaking to the outside. To alleviate this, a wheel 191 of a size that fits the secured space may be installed. In other words, the light output from the lamp 130 can be prevented from leaking to the outside by the light blocking unit 190 and the wheel 191. Referring to FIG. 3(b), which is a schematic cross-sectional view of the IPL sterilizing device 100, the wheel 191 disposed at one end of the light blocking unit 190 contacts the area to be sterilized and rotates by the user's force. can do.

The body 101 is not limited to the above-described description, such as additionally provided with a bumper (not shown) to cushion the impact.

The power supply unit 110 may provide current to drive at least one component of the IPL sterilization device 100. For example, the power supply unit 110 operates the capacitor 120, lamp 130, circuit unit 140, sensor unit 150, output unit 160, input unit 170, controller 180, etc. Current can be provided.

The power supply unit 110 may receive external or internal power under the control of the controller 180 and supply power to each component included in the IPL sterilization device 100. For example, the power supply unit 110 may include a battery, and the battery may be a built-in battery or a replaceable battery.

For another example, the power plug independently provided on one side of the IPL sterilizing device 100 may be connected to an outlet to provide current to operate the IPL sterilizing device 100.

Since the power supply unit 110 can be used as a normal power supply unit, detailed description will be omitted.

The capacitor 120 can accumulate electrical energy charged by the capacitor charger 143. The capacitor 120 may be a typical capacitor generally used in a circuit, and detailed description will be omitted.

The lamp 130 can output pulsed light. For example, the lamp 130 can sterilize objects to be sterilized in an area to be sterilized by outputting intense pulsed light (IPL) in a short pulse format.

The lamp 130 may emit light of multiple wavelengths. For example, the lamp 130 may receive electrical energy and output light having a wavelength including the visible light band. For example, the lamp 130 may emit light of a complex wavelength of 400-1200 nm rather than a single wavelength of light. Various filters are used in the lamp 130 to irradiate light in a desired wavelength range.

The lamp 130 is disposed in one area of the body 101 and can irradiate pulsed light in the visible light range of 400 to 1200 nm to the object to be sterilized. For example, the lamp 130 may be provided as a flash lamp such as a xenon lamp, and may emit light using supplied electrical energy. Of course, the lamp 130 is not limited to this, and may be made of an incandescent lamp, a xenon lamp, a laser diode, an LED, or a combination of two or more of these and others.

A light guide unit 131 may be disposed around the lamp 130 to guide the pulsed light output from the lamp 130. For example, the light guide unit 131 is disposed in an area around the lamp 130 and guides the pulse light output from the lamp 130 so that it is irradiated to at least a portion of the object to be sterilized. . To this end, the light guide unit 131 may be formed to extend a predetermined length around the lamp 130 so that a portion thereof protrudes.

The light guide unit 131 may be implemented in various shapes. For example, the light guide unit 131 may have a concave shape toward the lamp 130. For example, the light guide unit 131 is formed in an overall U-shaped structure so that the lamp 130 can be provided in the internal space, and can guide the light output from the lamp 130. Here, one end of the light guide unit 131 may protrude further toward the area to be sterilized than the lamp 130.

Additionally, a reflective surface may be formed in the light guide unit 131. For example, the reflective surface may be installed behind the lamp 130 to reflect the light output from the lamp 130 so that it reaches the object to be sterilized. For another example, the reflective surface may be installed in a shape that focuses the light output from the lamp 130 toward the object to be sterilized. The light guide unit 131 can easily allow the light output from the lamp 130 to reach the object to be sterilized, so that the object to be sterilized can be effectively sterilized.

The circuit unit 140 can control pulsed light output through the lamp 130 in various ways.

FIG. 4 is a diagram illustrating an example of a circuit for driving an IPL sterilization device according to an embodiment. Referring to FIG. 4, the IPL sterilization device 100 can be controlled by a strobe method that outputs pulsed light using a trigger voltage (or current) or a shimmer method that outputs pulsed light using a shimmer current (or voltage). You can.

Referring to FIG. 4(a), the IPL sterilizing device 100 can be controlled by a strobe method, and for this purpose, the IPL sterilizing device 100 includes a lamp 130, a capacitor charger 143, a capacitor 120, and a trigger. It may include a circuit portion 140a. The strobe method emits light through the lamp 130 until all of the energy charged in the capacitor 120 is discharged. It has the advantage of excellent power efficiency and is not difficult to charge, but the intensity of the output pulse light is different from each other. The disadvantage is that detailed control is difficult.

The capacitor charger 143 can charge the capacitor 120 according to a preset voltage. For example, the capacitor charger 143 may be a high-voltage capacitor charger. The capacitor charger 143 may be a typical capacitor charger, and detailed description will be omitted.

The capacitor 120 can accumulate electrical energy charged by the capacitor charger 143.

The trigger circuit unit 140a may turn on the lamp 130 by discharging the charge charged in the capacitor 120 to the lamp 130 through a trigger voltage (or current). For example, the trigger circuit unit 140a applies a high voltage (for example, about 10,000 to 20,000 volts) between the anode and cathode of the lamp 130 to turn on the lamp 130 from a non-lighting state. The gas in the tube of (130) can be ionized into a plasma state. The gas ionized by the trigger circuit unit 140a can rapidly form a discharge path for high voltage and turn on the lamp 130. Bringing the lamp 130 from a non-lighting state to an initial lighting state is called a trigger, and the trigger circuit unit 140a can output pulsed light by repeating the blinking of the lamp 130 in a rapid cycle in this manner. The circuit of FIG. 4(a) including the trigger circuit 140a may be controlled by the controller 180.

Referring to FIG. 4(b), the IPL sterilization device 100 can be controlled by a shimmer method, and the IPL sterilization device 100 includes a lamp 130, a capacitor charger 143, a capacitor 120, and a shimmer circuit unit ( 140b) may be included. Hereinafter, descriptions overlapping with FIG. 4(a) will be omitted. That is, technical ideas that can be used in FIG. 4(a) are not redundantly explained in FIG. 4(b).

The shimmer method is a method of controlling the emission amount of energy charged in the capacitor 120 to emit light through the lamp 130. It has the advantage of excellent lamp life and the ability to adjust the intensity of pulse light, allowing for detailed control. , there is a disadvantage in that power efficiency is reduced because constant energy must always be maintained in the circuit through simmer current (or simmer voltage).

The shimmer circuit unit 140b may maintain the lamp 130 in the shimmer state. For example, the shimmer circuit unit 140b may flow a shimmer current, which is the minimum current required to keep the lamp 130 lit by the trigger voltage (or current) in a continuous lighting state. The lamp 130, which has already been triggered and is in a dimmer state, may be turned on by being discharged when a voltage with large energy is applied from the capacitor 120 between the anode and the cathode. The circuit of FIG. 4(b) including the shimmer circuit unit 140b may be controlled by the controller 180.

Of course, Figure 4 is only an example for convenience of explanation and is not limited thereto. According to some embodiments, components may be added to, subtracted from, or further subdivided from the environment of FIG. 4. For example, the circuit unit 140 may further include a transformer provided for insulation and voltage boosting, a diode for converting alternating current boosted through the transformer into direct current, and a switch.

Figure 5 is a diagram for explaining the sensor unit 150 according to one embodiment. Referring to FIG. 5 , the sensor unit 150 may include various sensors to detect the surrounding environment of the IPL sterilizing device 100 or the state of the IPL sterilizing device 100.

For example, the sensor unit 150 may include a motion sensor 150a to detect movement of the IPL sterilizing device 100. For example, the motion sensor 150a may be implemented as an acceleration sensor, gyro sensor, geomagnetic sensor, etc. disposed inside or outside the IPL sterilization device 100. The IPL sterilization device 100 may be controlled based on sensing values obtained through the motion sensor 150a. Alternatively, the IPL sterilization device 100 may further include a wheel 191, and the sensor unit 150 may measure the number of rotations of the wheel 191. The controller 180 may calculate the movement (eg, movement speed, rotation, etc.) of the IPL sterilization device 100 based on the number of rotations of the wheel 191 measured through the sensor unit 150. Specifically, when the wheels 191 of the IPL sterilization device 100 are arranged as a pair on the left and right sides, the controller 180 based on the rotation speed of the left and right wheels 191 measured through the sensor unit 150. Rotation can be determined. For example, when the rotation speed of the left and right wheels 191 of the IPL sterilization device 100 is the same, the controller 180 determines that it is moving straight, and when the rotation speed of the left and right wheels 191 of the IPL sterilization device 100 are different. The controller 180 may determine that a rotational movement is being made.

For another example, the sensor unit 150 may include a state detection sensor 150b for detecting the state of the object to be sterilized. For example, the state detection sensor 150b may be implemented as an illumination sensor for detecting the illumination of the object to be sterilized, a temperature sensor for detecting the temperature of the object to be sterilized, etc. The IPL sterilization device 100 may be controlled based on the sensing value obtained through the state detection sensor 140b.

For another example, the sensor unit 150 may include a tilt sensor 150c that detects when the body 101 is turned over or tilted. For example, the IPL sterilization device 100 may be controlled based on a sensing value obtained through the tilt sensor 150c.

For another example, the sensor unit 150 may include a contact sensor 150d that detects when a portion of the IPL sterilization device 100 is in poor contact with the object to be sterilized. For example, the IPL sterilization device 100 may be controlled based on the sensing value obtained through the contact sensor 150d.

For another example, the sensor unit 150 may include a temperature sensor 150e for detecting the temperature of the IPL sterilization device 100. For example, the temperature sensor 150e may be placed inside or outside the body 101 and used to control the IPL sterilizing device 100 so that the temperature of the IPL sterilizing device 100 does not become too high.

For another example, the sensor unit 150 may include a distance sensor 150f for detecting the distance between a portion of the IPL sterilization device 100 and the object to be sterilized. For example, the distance sensor 150f may be placed inside or outside to detect the distance between the lamp 130 and the object to be sterilized. The IPL sterilization device 100 may be controlled based on the sensing value obtained through the distance sensor 150f.

The sensor unit 150 may output a sensor signal representing a voltage reflecting the sensed value. Alternatively, the sensor unit 150 may be configured to compare the sensing value with a preset threshold and output a sensor signal when the sensing value exceeds the preset threshold.

Of course, the sensor unit 150 may be implemented differently, such as including a pressure sensor, etc., and is not limited to the above description.

Additionally, if the controller 180 can independently confirm information sensed by the sensor unit 150, it may not use the sensing value of the sensor unit 150.

The output unit 160 may output information related to the status of the IPL sterilization device 100. For example, the output unit 160 may include an indicator that externally displays information related to the status of the IPL sterilization device 100 in various ways. For example, the indicator may be implemented with an LED lamp, speaker, motor, haptic device, vibrator, signal output circuit, etc. The indicator can visually or audibly output a start notification, an end notification, or a notification when a condition is abnormal during a sterilization or cleaning operation.

Additionally, the output unit 160 may include an LCD, OLED, AMOLED display, etc. Here, when the output unit 160 is provided as a touch screen, the output unit 160 can perform the function of the input unit 170. In this case, a separate input unit 170 may not be provided depending on selection, and an input unit 170 that performs limited functions such as volume control, power button, and home button may be provided.

The input unit 170 may obtain a signal corresponding to the user's input. For example, the input unit 170 may receive a user's input to perform a sterilizing operation or a cleaning operation. For example, the input unit 170 may receive user input related to the mode, intensity, time, and pattern of power on/off, sterilization operation, or cleaning operation.

Additionally, the input unit 170 may include a keyboard, keypad, buttons, jog shuttle, wheel, etc. Additionally, the user's input on the input unit 170 may be, for example, a button press, touch, or drag. Additionally, when the output unit 160 is implemented as a touch screen, the output unit 160 may serve as the input unit 170.

According to one embodiment, the input unit 170 may be composed of a separate module connected wirelessly or wired to the IPL sterilization device 100. For example, the IPL sterilization device 100 may receive input for sterilization or cleaning from the user through the input unit 170 composed of a separate module given to the user's hand. For example, the IPL sterilization device 100 may receive input for sterilization or cleaning from a mobile terminal, and in this case, the IPL sterilization device 100 may include a separate communication unit (not shown).

As another example, the IPL sterilization device 100 may be located within a predetermined distance from the object to be sterilized.

The IPL sterilization device 100 can sterilize objects to be sterilized by outputting pulsed light (S2000).

For example, the controller 180 may control the IPL sterilization device 100 to output pulsed light according to a preset sterilization pattern. For example, the controller 180 may control the IPL sterilization device 100 to output pulsed light according to the sterilization mode input by the user. For another example, the controller 180 may control the IPL sterilization device 100 to output pulsed light according to the sensing value detected through the sensor unit 150. For example, the controller 180 may adjust the sterilization mode according to the movement of the IPL sterilization device 100 detected through the sensor unit 150.

In one embodiment, the controller 180 may control a sterilization operation performed through the IPL sterilization device 100. For example, the controller 180 may change detailed properties of the sterilization operation performed through the IPL sterilization device 100, such as intensity, time, type, and mode. For example, the controller 180 may control the output of pulsed light by the lamp 130.

Of course, the IPL sterilization device 100 may be controlled in other ways, such as sterilizing objects to be sterilized with a random IPL output pattern without a fixed IPL output pattern, and is not limited to the above-described description.

FIG. 7 is a diagram illustrating a pulse voltage applied for pulsed light output according to an embodiment. Referring to FIG. 7, various pulse voltages may be applied to the lamp 130 to output pulse light depending on time. The controller 180 can adjust various properties (eg, voltage level, period, pulse width, etc.) of the applied pulse voltage.

Referring to FIG. 7(a), a pulse voltage having a pulse width W1, a period T1, and a voltage level V1 may be applied to the lamp 130 to output pulse light. The applied pulse voltage may be set to have a sterilizing intensity sufficient to sterilize the object to be sterilized. The sterilizing intensity may vary based on the intensity, period, pulse width, etc. of the output pulse light. In general, when other properties of the output pulse light are the same, the greater the intensity of the output pulse light, the shorter the period, and the larger the pulse width, the stronger the sterilization intensity can be.

The controller 180 may apply a pulse voltage whose period (or frequency) is adjusted to the lamp 130. Referring to FIG. 7(b), for pulse light output, a pulse voltage having a period T2 different from the pulse voltage of FIG. 7(a) may be applied to the lamp 130, that is, pulse light of a different period may be applied to the lamp 130. It can be output from (130).

The controller 180 may apply a pulse voltage whose voltage level is adjusted to the lamp 130. Referring to FIG. 7(c), for pulse light output, a pulse voltage having a voltage level V2 different from the pulse voltage of FIG. 7(a) may be applied to the lamp 130, that is, pulse light of different intensity may be applied to the lamp 130. It can be output from (130).

The controller 180 may apply a pulse voltage with an adjusted pulse width to the lamp 130. Referring to FIG. 7(d), a pulse voltage having a different pulse width W2 from the pulse voltage of FIG. 7(a) may be applied to the lamp 130 for pulse light output, that is, pulse light of a different pulse width. This can be output from lamp 130.

Additionally, the pulse voltage shown in FIG. 7 is only an example for convenience of explanation and is not limited thereto. For example, the pulse voltage may be adjusted in other ways, such as applying a pulse voltage with a changed waveform, and is not limited to the above description.

Let us return to Figure 6 again for explanation.

The IPL sterilizing device 100 can detect the movement of the IPL sterilizing device 100 (S3000).

For example, the controller 180 may detect the movement of the IPL sterilizing device 100 based on the sensing value of the sensor unit 150 including the motion sensor 150a. Here, movement may include movement speed, movement direction, rotation direction, rotation speed, acceleration, etc. For example, the controller 180 may check the movement speed, movement direction, rotation direction, rotation speed, acceleration, etc. of the IPL sterilization device 100 based on the sensing value of the sensor unit 150.

The IPL sterilizing device 100 may control its operation based on the movement of the IPL sterilizing device 100 (S4000).

For example, the controller 180 may control the presence or absence of pulsed light output by the lamp 130 according to the movement of the IPL sterilization device 100. As another example, the controller 180 may provide notifications based on movement of the IPL sterilizing device 100. For another example, the controller 180 may output pulsed light corresponding to the movement of the IPL sterilization device 100 through the lamp 130. For example, the controller 180 outputs a first pulse light through the lamp 130 when the IPL sterilizing device 100 is first moved, and when the IPL sterilizing device 100 is second moved, the controller 180 outputs a second pulse light. Can be output through the lamp 130.

In one embodiment, the controller 180 may output pulsed light based on at least one of the movement speed, movement direction, and rotation of the IPL sterilization device 100.

The controller 180 may control pulsed light output by the lamp 130 based on the moving speed of the IPL sterilization device 100. For example, the controller 180 may control the presence or absence of pulsed light output by the lamp 130 according to the moving speed of the IPL sterilization device 100. For another example, the controller 180 may change the properties of the pulse light output by the lamp 130 according to the moving speed of the IPL sterilization device 100.

8 to 12 are diagrams for explaining pulsed light output based on the moving speed of the IPL sterilization device according to an embodiment.

Referring to FIG. 8, you can see the change in movement speed of the IPL sterilization device 100 over time. The controller 180 applies a pulse voltage whose various properties (eg, voltage level, period, pulse width, etc.) are adjusted based on the moving speed of the IPL sterilization device 100 and outputs pulse light through the lamp 130. can do. For example, the controller 180 may apply a pulse voltage corresponding to a specific movement speed of the IPL sterilization device 100 and output specific pulse light through the lamp 130.

Referring to FIG. 8(a), while the IPL sterilizing device 100 moves at a moving speed s1 from 0 to t1, the IPL sterilizing device 100 outputs the first pulse light, and the IPL sterilizing device 100 moves at a moving speed s1. After t1 moves to s3, the IPL sterilization device 100 may output the second pulse light.

In one embodiment, the controller 180 may apply a pulse voltage corresponding to a specific movement speed range of the IPL sterilization device 100 and output specific pulse light through the lamp 130. For example, while the IPL sterilizing device 100 moves in the first moving speed range, the IPL sterilizing device 100 outputs the first pulse light, and the IPL sterilizing device 100 moves in the second moving speed range. During this time, the IPL sterilization device 100 may output the second pulse light. Referring to FIG. 8(b), while the IPL sterilizing device 100 moves in the moving speed range s1 to s2 from 0 to t1, the IPL sterilizing device 100 outputs the first pulse light, and the IPL sterilizing device 100 After t2, which moves at the moving speed range s3 to s4, the IPL sterilizing device 100 may output the second pulse light.

In addition, the controller 180 applies a pulse voltage with various properties (eg, voltage level, period, pulse width, etc.) adjusted based on the change in movement speed of the IPL sterilization device 100 to the lamp 130 to produce pulse light. Can be output through the lamp 130. For example, while the movement speed of the IPL sterilization device 100 changes from the first movement speed at which the first pulse light is output to the second movement speed at which the second pulse light is output, the third movement speed corresponding to the change in movement speed is changed. Pulsed light can be output. For example, when the IPL sterilization device 100 changes from the first moving speed to the second moving speed, the properties between the first pulse light output at the first moving speed and the second pulse light output at the second moving speed It is possible to output pulsed light having . Referring to FIG. 8(b), the pulse light output during t1 to t2 when the moving speed changes is divided into the first pulse light output when the moving speed range is s1 to s2 and the second pulse light output when the moving speed range is s3 to s4. It may be pulsed light with average properties. Alternatively, the pulse light output during t1 to t2 when the moving speed changes may output a separate pulse light or may stop outputting pulse light altogether.

Referring to FIG. 9, a graph of the movement speed of the IPL sterilization device 100 over time and pulse voltages applied for pulse light output based on the movement speed are shown. A first set of pulse voltages are applied to the lamp 130 when the IPL sterilizing device 100 moves at a first moving speed, and a second set of pulse voltages are applied to the lamp 130 when the IPL sterilizing device 100 moves at a second moving speed. 130). The pulse voltage set can be interpreted as a plurality of pulse voltages applied for a preset time, the first pulse voltage set includes a plurality of first unit pulse voltages, and the second pulse voltage set includes a plurality of second unit pulse voltages. may include.

In one embodiment, the high level application time of the pulse per unit time of the first pulse voltage set and the second pulse voltage set may be different depending on the moving speed. For example, the first pulse voltage set applied when moving at the first moving speed and the second pulse voltage set applied when moving at the second moving speed may have different high-level pulse application times per unit time. For example, the high level application time of the pulse per unit time of the first pulse voltage set applied when moving at the first moving speed is the unit time of the second pulse voltage set applied when moving at the second moving speed faster than the first moving speed. It may be shorter than the high level application time of each pulse.

In one embodiment, a set of pulse voltages with different periods between unit pulse voltages may be applied depending on the moving speed. For example, a first period between the unit pulse voltages of the first pulse voltage set applied when moving at the first moving speed and the unit pulse voltages between the unit pulse voltages of the second pulse voltage set applied when moving at the second moving speed. The second period may be different. For example, the first period between the unit pulse voltages of the first pulse voltage set applied when moving at the first moving speed is the unit of the second pulse voltage set applied when moving at the second moving speed faster than the first moving speed. It may be longer than the second period between pulse voltages. This is to prevent the object to be sterilized from being sufficiently sterilized by outputting pulsed light more frequently than when the IPL sterilizing device 100 moves quickly. Of course, the first period between the unit pulse voltages of the first pulse voltage set applied when moving at the first moving speed is the unit pulse of the second pulse voltage set applied when moving at the second moving speed slower than the first moving speed. It is not limited to the above description, such that it can be longer than the second period between voltages.

Referring to FIGS. 9(a) and 9(b), the period between the first unit pulse voltages of the first pulse voltage set applied when moving at the first moving speed is the period between the first unit pulse voltages applied when moving at the second moving speed. The period between the second unit pulse voltages of the two-pulse voltage set may be different. For example, when the IPL sterilizing device 100 moves at a moving speed s1, the IPL sterilizing device 100 may output a first pulse voltage set whose period between unit pulses is T1, and the IPL sterilizing device 100 ) moves at a moving speed s3, the IPL sterilization device 100 may output a second pulse voltage set whose period between unit pulses is T2. Here, when s1 is smaller than s3, T1 may be larger than T2.

In one embodiment, a set of pulse voltages with different pulse widths may be applied depending on the moving speed. For example, the first pulse voltage set applied when moving at the first moving speed and the second pulse voltage set applied when moving at the second moving speed may have different pulse widths. For example, the first pulse width of the first pulse voltage set applied when moving at the first moving speed may be smaller than the second pulse width of the second pulse voltage set applied when moving at the second moving speed faster than the first moving speed. You can. This is to prevent the object to be sterilized from being sufficiently sterilized by outputting pulsed light with a longer pulse width when the IPL sterilizing device 100 moves quickly. Of course, the first pulse width of the first pulse voltage set applied when moving at the first moving speed may be smaller than the second pulse width of the second pulse voltage set applied when moving at the second moving speed slower than the first moving speed. It is not limited to the above description.

Referring to FIGS. 9(a) and 9(c), the pulse width of the first unit pulse voltages of the first pulse voltage set applied when moving at the first moving speed is the pulse width of the second unit pulse voltages applied when moving at the second moving speed. The pulse width of the second unit pulse voltages of the pulse voltage set may be different. For example, when the IPL sterilizing device 100 moves at a moving speed s1, the IPL sterilizing device 100 may output a first pulse voltage set whose unit pulses have a pulse width of W1, and the IPL sterilizing device 100 When moving at a moving speed s3, the IPL sterilization device 100 may output a second pulse voltage set whose unit pulses have a pulse width of W2. Here, when s1 is smaller than s3, W1 may be smaller than W2.

Referring to FIG. 10, a graph of the movement speed of the IPL sterilization device 100 over time and pulse voltages applied for pulse light output based on the movement speed are shown. In one embodiment, a set of pulse voltages with different voltage levels may be applied depending on the moving speed. For example, the first pulse voltage set applied when moving at the first moving speed and the second pulse voltage set applied when moving at the second moving speed may have different voltage levels. For example, the first voltage level of the first pulse voltage set applied when moving at a first moving speed may be lower than the second voltage level of the second pulse voltage set applied when moving at a second moving speed faster than the first moving speed. You can. This is to prevent the object to be sterilized from being sufficiently sterilized by outputting pulsed light with a stronger intensity when the IPL sterilizing device 100 moves quickly. Of course, the first voltage level of the first pulse voltage set applied when moving at the first moving speed may be lower than the second voltage level of the second pulse voltage set applied when moving at the second moving speed slower than the first moving speed. It is not limited to the above description.

Referring to FIGS. 10(a) and 10(b), the voltage level of the first unit pulse voltages of the first pulse voltage set applied when moving at the first moving speed is the voltage level of the second unit pulse voltages applied when moving at the second moving speed. The voltage levels of the second unit pulse voltages of the pulse voltage set may be different. For example, when the IPL sterilizing device 100 moves at a moving speed s1, the IPL sterilizing device 100 may output a first pulse voltage set whose voltage level of unit pulses is V1, and the IPL sterilizing device 100 When moving at a moving speed s3, the IPL sterilization device 100 may output a second pulse voltage set whose voltage level of unit pulses is V2. Here, when s1 is smaller than s3, V1 may be smaller than V2.

Additionally, the graphs shown in FIGS. 8 to 10 are merely examples for convenience of explanation and are not limited thereto.

In one embodiment, the controller 180 may output a set of pulse voltages to the lamp 130 based on a sensor signal output from the sensor unit 150. For example, the controller 180 may output a set of pulse voltages to the lamp 130. If a new sensor signal is input while outputting, the pulse voltage set according to the new sensor signal can be output after the output of the pulse voltage set being output is completed. For example, if the controller 180 receives a new first sensor signal while receiving the first sensor signal and outputting the first pulse voltage set, the new first sensor signal is input after the output of the first pulse voltage set is completed. A first pulse voltage set according to the sensor signal may be output.

11 and 12 are examples of pulse voltage set output based on sensor signals according to one embodiment.

Referring to FIG. 11, a graph of the sensor signal output from the sensor unit 150 of the IPL sterilization device 100 over time and pulse voltages applied for pulse light output are shown. The IPL sterilizing device 100 pulses based on sensor signals (U11, U12, U13, U14, U15, U16, U17, U21, U22, U23, U24, U25, U26...) output from the sensor unit 150. Voltage sets (PVS 11, PVS12, PVS 2...) can be output. Here, the sensor unit 150 used may include, for example, a motion sensor 150a. When receiving the sensor signal U11, the controller 180 may output a pulse voltage set PVS 11 that corresponds to the sensor signal U11 and has a period between pulses T1. While the controller 180 receives the sensor signal U11 and outputs the pulse voltage set PVS 11, it can maintain the output of the pulse voltage set PVS 11 even if it receives new sensor signals U12, U13, and U14. After receiving U11 and completing the output of the pulse voltage set PVS 11, the controller 180 receives a new sensor signal U15, corresponds to the sensor signal U15, and outputs a pulse voltage set PVS 12 whose period between pulses is T1. can do. Here, when the magnitudes of the sensing values of the sensor signal U11 and the sensor signal U15 are the same, the output pulse voltage sets PVS 11 and PVS 12 may be the same. While the controller 180 receives the sensor signal U15 and outputs the pulse voltage set PVS 12, it can maintain the output of the pulse voltage set PVS 12 even if it receives new sensor signals U16, U17, and U21.

When receiving the sensor signal U22, the controller 180 may output a pulse voltage set PVS 2 that corresponds to the sensor signal U22 and whose period between pulses is T2. Here, the period between the pulses of each of the pulse voltage sets PVS 11, PVS 12 and PVS 2 is adjusted based on the moving speed of the IPL sterilizing device 100 reflected by the input sensor signal, and the moving speed reflected by the sensor signal The larger the period of the pulse voltage set, the smaller the period can be. Of course, the width of the pulse voltage set, pulse width, etc. may be adjusted depending on the moving speed reflected by the sensor signal.

While the controller 180 receives the sensor signal U22 and outputs the pulse voltage set PVS 2, it can maintain the output of the pulse voltage set PVS 2 even if it receives new sensor signals U23 and U24.

Optionally, if the size of the sensing value of the new sensor signal U21 is different from the size of the sensing value of the previously received sensor signals U15, U16, and U17, the output of the pulse voltage set PVS 12 is terminated without maintaining the sensor signal. It is possible to control it in other ways, such as by receiving U21 as input and outputting a new pulse voltage set, PVS 2.

For another example, if a new sensor signal is received while the controller 180 is outputting a pulse voltage set, it stops outputting the pulse voltage set that is already being output and generates a new pulse voltage set in response to the new sensor signal. Can be printed. For example, when the controller 180 receives the first sensor signal while outputting the first pulse voltage set, it stops outputting the first pulse voltage set that is already being output and responds to the first sensor signal again. A first set of pulse voltages may be output. That is, the controller 180 may output a set of pulse voltages in response each time a sensor signal is received from the sensor unit 150. Through this, the controller 180 can immediately respond to the moving speed of the IPL sterilization device 100 and adjust the output pulse voltage set, thereby enabling sufficient sterilization of the area to be sterilized.

Referring to FIG. 12, a graph of the sensor signal output from the sensor unit 150 of the IPL sterilization device 100 over time and pulse voltages applied for pulse light output are shown. The IPL sterilization device 100 generates a pulse voltage set (PVS 31, PVS 32, PVS 33, PVS) based on the sensor signals (U31, U32, U33, U41, U42) output from the sensor unit 150. 4 ㆍㆍ) can be output. Here, the sensor unit 150 used may include, for example, a motion sensor 150a. When receiving the sensor signal U31, the controller 180 may output a pulse voltage set PVS 31 that corresponds to the sensor signal U31 and has a period T3 between pulses. When the controller 180 receives a new sensor signal U32 while receiving the sensor signal U31 and outputting the pulse voltage set PVS 3, it stops outputting the pulse voltage set PVS 31 and responds to the received sensor signal U32. Thus, the pulse voltage set PVS 32 can be output. Specifically, the controller 180 receives the sensor signal U31 and outputs pulse voltages PV311 and PV312 while outputting a pulse voltage set PVS 31 including pulse voltages PV311, PV312, and PV313, and then receives a new sensor signal U32. In this case, instead of outputting the pulse voltage PV313 according to the pulse voltage set PVS 31, the pulse voltage set PVS 32 may be newly output in response to the received sensor signal U32. Accordingly, the interval Tx between the output pulse voltage and the newly output pulse voltage may be different from the period T3 and T4 between the pulse voltages included in the pulse voltage sets.

The controller 180 receives the sensor signal U32 and outputs pulse voltages PV321 and PV3222 while outputting a pulse voltage set PVS 32 including pulse voltages PV321, PV322, and PV323. When receiving a new sensor signal U33, the controller 180 outputs pulse voltages PV321 and PV3222. Instead of outputting the pulse voltage PV323 according to the voltage set PVS 32, the pulse voltage set PVS 33 can be newly output in response to the input sensor signal U33.

Here, when the magnitudes of the sensing values of the sensor signal U31, sensor signal 32, and sensor signal U33 are the same, the output pulse voltage sets PVS 31, PVS 32, and PVS 33 may be the same.

The controller 180 may receive the sensor signal U41 and output a pulse voltage set PVS 4. The controller 180 may synchronize the period of receiving the sensor signal and the period between the pulse voltages in order to keep the period between the output pulse voltages constant. For example, the controller 180 matches the period of receiving the sensor signal U41 and the sensor signal U42 and the period of the pulse voltage set to be the same, so that even when receiving the new sensor signal U42, the period between the pulse voltages does not change. A set of pulse voltages can be output. Here, the period between pulses of each of the pulse voltage sets PVS 31, PVS 32, PVS 33 and PVS 4 is adjusted based on the moving speed of the IPL sterilizing device 100 reflected by the input sensor signal, and the sensor signal is reflected. The larger the moving speed, the smaller the period of the pulse voltage set. Of course, the width of the pulse voltage set, pulse width, etc. may be adjusted depending on the moving speed reflected by the sensor signal.

Additionally, the graphs shown in FIGS. 11 and 12 are merely examples for convenience of explanation and are not limited thereto.

In one embodiment, the controller 180 may control pulsed light output by the lamp 130 based on the moving direction of the IPL sterilization device 100. For example, the controller 180 may control the presence or absence of pulsed light output by the lamp 130 according to the moving direction of the IPL sterilization device 100. For another example, the controller 180 may change the properties of the pulse light output by the lamp 130 depending on the moving direction of the IPL sterilizing device 100. Additionally, the controller 180 may control pulsed light output by the lamp 130 based on a sensor signal reflecting the moving direction of the IPL sterilization device 100.

In one embodiment, the controller 180 may control pulsed light output by the lamp 130 based on the rotational movement of the IPL sterilization device 100. For example, the controller 180 can control the presence or absence of pulsed light output by the lamp 130 depending on whether the IPL sterilization device 100 is rotated. For another example, the controller 180 may change the properties of pulsed light output by the lamp 130 based on the rotation of the IPL sterilizing device 100. Here, the properties of the output pulse light can be adjusted according to the properties of the rotational movement of the IPL sterilization device 100 (eg, rotation speed, rotation direction, etc.). Additionally, the controller 180 may control pulsed light output by the lamp 130 based on a sensor signal reflecting the rotational movement of the IPL sterilization device 100.

Figures 13 and 14 are diagrams for explaining the provision of notifications based on the movement speed of the IPL sterilizing device according to an embodiment.

In order to sterilize an object to be sterilized, pulsed light must be able to be irradiated to the object to be sterilized. In the case of the IPL sterilization device 100 according to one embodiment, since it moves by the user's force, if it moves at a speed faster than the output cycle of the pulse light, the pulse light is not irradiated to the object to be sterilized, so the object to be sterilized may not be sterilized. In addition, when pulsed light is continuously irradiated to the object to be sterilized through the IPL sterilization device 100 according to one embodiment, the temperature of the object to be sterilized increases excessively due to the pulsed light, which may cause damage to the object to be sterilized or cause safety problems such as fire. You can. In order to solve these problems, the operation of the IPL sterilizing device 100 needs to be controlled based on the movement of the IPL sterilizing device 100.

In one embodiment, controller 180 may provide notifications based on the movement speed of IPL sterilization device 100. For example, the controller 180 may control the output unit 160 including an indicator indicating the state of the IPL sterilizing device 100 based on the moving speed of the IPL sterilizing device 100. For example, the controller 180 may control the output unit 160, which includes an indicator that outputs visual information, such as an LED lamp, to provide a visual notification. As another example, the controller 180 may control the output unit 160, which includes an indicator that outputs auditory information, such as a speaker, to provide an auditory notification. As another example, the controller 180 may provide a vibration notification by controlling the output unit 160, which includes an indicator that outputs vibration, such as a vibrator.

The controller 180 may provide a notification when the movement speed of the IPL sterilization device 100 is a specific movement speed. For example, the controller 180 may provide a notification through the output unit 160 including an indicator when the IPL sterilizing device 100 moves at a specific moving speed. For example, when the IPL sterilization device 100 moves at a specific movement speed, the controller 180 outputs a specific pulse light and simultaneously provides a notification through the output unit 160 including an indicator.

For another example, the controller 180 may provide a notification through the output unit 160 including an indicator when the movement speed of the IPL sterilization device 100 reaches a preset threshold speed. The preset threshold speed may be determined by considering the period of pulsed light output from the IPL sterilization device 100. As an example, the controller 180 may determine the speed at which the IPL sterilization device 100 moves equal to the length of the sterilizable area during the period of the pulse light output from the IPL sterilization device 100 as the critical speed.

Referring to FIG. 13(a), when the IPL sterilization device 100 moves at a moving speed s1, it outputs a first pulse voltage set to the lamp 130 to output a first pulse light, and the moving speed is equal to or higher than the threshold speed. In this case, a first notification can be provided through the output unit 160 including an indicator. The output unit 160 including an indicator may provide a second notification even when outputting the first pulse light, and the second notification may be different from the first notification.

Additionally, the controller 180 may provide a notification through the output unit 160 including an indicator when the IPL sterilizing device 100 moves at a moving speed greater than a preset threshold speed for a preset time. Referring to FIG. 13(b), when the IPL sterilization device 100 moves at a moving speed s1, it outputs a first pulse voltage set to the lamp 130 to output a first pulse light, and the moving speed is equal to or higher than the threshold speed. When it reaches, a notification is not immediately provided through the output unit 160 including an indicator, but a notification can be provided when the IPL sterilizing device 100 moves at a moving speed greater than the preset threshold speed for a preset time. .

The controller 180 may provide a notification when the movement speed of the IPL sterilizing device 100 is zero (i.e., when the movement stops). For example, the controller 180 may provide a notification through the output unit 160 including an indicator when the IPL sterilization device 100 maintains a movement speed of 0 for more than a preset threshold time. Here, the controller 180 may control the lamp 130 to stop outputting pulse light.

The critical time is to prevent the temperature of the object to be sterilized to which pulsed light is repeatedly irradiated from excessively increasing, and may be set in consideration of the sterilizing intensity of the IPL sterilizing device 100. For example, the critical time may be determined based on the properties of pulsed light output from the IPL sterilization device 100. For example, the greater the intensity of the pulse light output from the IPL sterilization device 100, the shorter the cycle, and the greater the pulse width, the smaller the critical time may be determined.

Referring to FIG. 14(a), the IPL sterilization device 100 may provide a notification through the output unit 160 including an indicator after t4 when the time stopped at a moving speed of 0 exceeds the threshold time.

Referring to FIG. 14(b), the IPL sterilization device 100 may stop outputting pulse light by the lamp 130 from t4, when the time stopped at a moving speed of 0 exceeds the critical time.

Figure 15 is a diagram for explaining an IPL sterilization device according to another embodiment.

In one embodiment, the IPL sterilization device 100 may be provided in an automatically moving form. For example, the IPL sterilization device 100 may be implemented as a robot sterilization device that travels around an area to be sterilized on its own.

To this end, the IPL sterilizing device 100 may further include a driving unit 192 for moving the IPL sterilizing device 100. That is, the IPL sterilization device 100 may be implemented in the form of a robot sterilization device that automatically travels through the driving unit 192.

For example, the driving unit 192 may move the IPL sterilizing device 100 under the control of the controller 180. For example, the driving unit 192 can move the IPL sterilizing device 100 straight forward or pivot, and can move the IPL sterilizing device 100 forward, backward, rotation, etc.

For this purpose, the driving unit 192 may include a wheel 191 and a driving motor (not shown).

The wheel 191 is disposed on the bottom of the body 101 and can be rotated forward/reverse through a drive motor. For example, the wheels 191 may be arranged on both sides of the bottom of the body 101 and rotated by a drive motor. The IPL sterilization device 100 can have various movements through the wheel 191 that rotates according to the rotation direction and rotation rate of the drive motor.

The suction unit 194 may generate suction force for suctioning foreign substances. For example, the suction unit 194 may be implemented including a suction motor (not shown), a blowing fan (not shown), etc. The suction unit 194 may be connected to the filter 195 and/or the dust collection unit 196. The filter 195 can prevent foreign substances such as dust from entering the suction unit 194 from the dust collection unit 196.

The dust collection unit 196 may collect and store foreign substances such as dust flowing into the body 101 through an inlet 198 formed in one area. To this end, the inlet pipe 197 may be disposed between the inlet 198 and the dust collection unit 196, and may form a path through which foreign substances flowing in through the inlet 154 are provided to the dust collection unit 196. For example, the inlet pipe 197 and the inlet 198 may be fastened to each other by a fastening means, and the inlet pipe 197 and the dust collection unit 196 may be fastened to each other by another fastening means. A brush 199 may be installed at the inlet 198 of the body 101 to sweep away foreign substances such as dust. The brush 199 is rotatably installed to sweep away dust from objects to be sterilized adjacent to the inlet 198.

Optionally, the cleaning unit 193 may include a mopping unit (not shown) for mopping the area to be sterilized. The mop unit is disposed in one area of the lower part of the body 101 and can be moistened by continuously supplying water. For example, the IPL sterilizing device 100 may include a water storage unit (not shown) that stores water inside the body 101, and a water supply unit (not shown) that supplies water from the water storage unit to the mop. There is a mop unit that continuously supplies water, so you can clean the floor with water. Here, the mop part may be implemented in a form that allows attachment and detachment.

Of course, the cleaning unit 193 may be implemented differently, such as including an air discharge unit that discharges the filtered air from which foreign substances have been filtered out in the dust collection unit 196 to the outside, and is not limited to the above description.

The method according to the embodiment may be implemented in the form of program instructions that can be executed through various computer means and recorded on a computer-readable medium. The computer-readable medium may include program instructions, data files, data structures, etc., singly or in combination. Program instructions recorded on the medium may be specially designed and configured for the embodiment or may be known and available to those skilled in the art of computer software. Examples of computer-readable recording media include magnetic media such as hard disks, floppy disks, and magnetic tapes, optical media such as CD-ROMs and DVDs, and magnetic media such as floptical disks. -Includes optical media (magneto-optical media) and hardware devices specifically configured to store and execute program instructions, such as ROM, RAM, flash memory, etc. Examples of program instructions include machine language code, such as that produced by a compiler, as well as high-level language code that can be executed by a computer using an interpreter, etc. The hardware devices described above may be configured to operate as one or more software modules to perform the operations of the embodiments, and vice versa.

As described above, although the embodiments have been described with limited examples and drawings, various modifications and variations can be made by those skilled in the art from the above description. For example, the described techniques are performed in a different order than the described method, and/or components of the described system, structure, device, circuit, etc. are combined or combined in a different form than the described method, or other components are used.
