When inserting the filter into the case body, the case body detects the inductive part to determine the type of the inductive part and at the same time confirms whether the filter has been inserted to the predetermined position. Since the filter and case body are installed removably, a filter with a predetermined wavelength can be inserted into the case body when the user wants to use multiple filters. This can solve the problem of not being able to easily replace the filter of a conventional hair loss device. Additionally, when installing inductive components in a filter, there are several ways to install inductive components in the filter. In a design with multiple functions, mass production of filters can be realized and manufacturing costs can be reduced by installing various inductive components.

2. In the present invention, the case main body includes a light-emitting structure, and the light-emitting structure includes the main body, a transparent crystal installed in the main body, and a lamp.

The power switch 114 and the light emitting button 15 are exposed to the outside of the case 11 and are electrically connected to the light emitting structure 12. An external power source supplies power to the light emitting structure 12 through the condenser 14.

At least one inductive component 201 is mounted on the filter 20. When inserting the filter 20 into the case body 10, the case body 10 can confirm the insertion of the filter 20 by detecting the inductive component 201. The hair removal device 1 is activated by turning on the power switch 114, and the light emission of the light-emitting structure 12 is controlled by the light-emitting button 15, thereby controlling the irradiation of light from the light-emitting structure 12 onto the skin. can do. The heat dissipation structure 13 dissipates heat from the light emitting structure 12 by sucking air.

Inside the case body 10, an induction device corresponding to the induction component 201 is installed. For example, when the induction device in the case body 10 is a Hall induction device, the induction component 201 is a magnetic component, and the induction device in the case body 10 is a photoelectric induction device. When the induction part 201 is a light reflecting part, a light absorbing part, or a light blocking part, and the induction device in the case body 10 is a fretting induction device, the induction part 201 may be a touch part. there is.

The case body 10 further includes a button PCBA (Printed Circuit Board Assembly) 16 and a main control PCBA 17 that are electrically connected. The light emitting structure 12, the heat dissipation structure 13, and the condenser 14 can form a stable structure by being sequentially connected to one side of the main control PCBA (17), and the button PCBA (16) is connected to one side of the main control PCBA (17). It is placed on the other side. With this arrangement method, module arrangement can be formed inside the case body 10, simplifying the structure and saving space. The power switch 114 and the light emitting button 15 may be electrically connected to the light emitting structure 12 by the button PCBA 16.

The display panel 101 can display one or more of functions, tap positions, temperature, power, time, etc., but the present invention is not limited to this.

1 to 5, the light emitting structure 12 includes a main body 121, a transparent crystal 125 and a lamp 122 installed within the main body 121. A light exit port 1211 is formed on the main body 121, one end of the transparent crystal 125 is exposed to the light exit port 1211 and can contact the user's skin, and the other end of the transparent crystal 125 is facing the lamp 122. The light emitted from the lamp 122 may pass through the transparent crystal 125 and then be emitted to the outside through the light exit port 1211. The filter 20 is inserted into the body 121 from the narrow side of the case body 10 and is located between the transparent crystal 125 and the lamp 122.

The transparent crystal 125 cools the user's skin by contacting it, and can also reduce the rays of the lamp 122 from giving a burning sensation to the user's skin. The transparent crystal 125 may be any one of sapphire crystal, quartz glass, and K9 glass, but the present invention is not limited to these.

The case body 10 and the light exit port 1211 have four adjacent sides, and the four sides form a narrow side and a wide side. Since the filter 20 is inserted into the main body 121 from the narrow side of the case main body 10, the size of the hole into which the filter 20 is inserted can be reduced. Since the hole formed on the surface of the case body 10 is small, foreign substances can be prevented from entering the body 121. When the filter 20 is inserted into the case body 10, the exposed portion of the filter 20 becomes smaller. This reduces the influence of the filter 20 on the appearance of the hair removal device and improves the user's experience.

A side mounting hole 1212 is further formed in the main body 121, and an insertion hole 111 corresponding to the side mounting hole 1212 is formed in the case 11. After passing through the insertion hole 111 and the side mounting hole 1212, the filter 20 is detachably coupled to the main body 121 so as to be positioned between the light exit port 1211 and the lamp 122. The space between the lamp 122 and the light exit port 1211 is exposed to the outside of the case body 10 due to the formation of the insertion hole 111 and the side mounting hole 1212, so the filter 20 is installed in this space. The filter 20 can be easily inserted or taken out within this space. As a result, the problem of not being able to easily replace the filter 20 of a conventional hair loss device can be solved by inserting the filter 20 having various wavelengths into the space.

In an embodiment of the present invention, the case 11 includes an upper case 112 and a lower case 113. The upper case 112 and lower case 113 may be integrally assembled using screws or coupling means, or the upper case 112 and lower case 113 may be integrally molded. Since the upper case 112 and lower case 113 of this embodiment are detachably coupled by a snap fit method, the parts inside can be repaired after removing the upper case 112 or lower case 113. You can. The insertion hole 111 is formed by combining the upper case 112 and the lower case 113.

The threshold of the magnetic field intensity of the Hall element 18 can be set in advance. When the filter 20 is inserted into the main body 121, the inductive component 201 slowly approaches a predetermined Hall element 18, so that the Hall element 18 can detect a slow increase in magnetic field strength. The magnetic field intensity increases until the inductive component 201 moves to a position corresponding to the Hall element 18. Hall element 18 transmits a start signal to the control unit. That is, the control unit is turned on at the position of the Hall element 18. In this state, the control unit starts the hair removal device 1 by receiving the startup signal from the power switch 114 again. Thereafter, the lamp 122 is made to emit light by pressing the light emitting button 15. When the filter 20 is not inserted into the main body 121, the Hall element 18 cannot detect the magnetic field strength, so the power switch 114 cannot play the role of opening and closing, and the light emitting button 15 also operates as the lamp 122. The opening and closing cannot be controlled.

The quantity of Hall elements 18 and the quantity of inductive components 201 may be the same or different. When inserting the inductive component 201 into the main body 121, at least one inductive component 201 is matched with a predetermined Hall element 18, but any of the inductive components 201 can be used as long as the present invention can be used normally.

The present invention does not limit the specific location where the inductive component 201 is installed in the filter 20. The induction component 201 may be installed at any position of the filter 20 as long as filtration of the filter 20 can be ensured. The Hall element 18 can be installed at a predetermined position depending on the position of the induction component 201. That is, when inserting the filter 20 into the main body 121, the Hall element 18 can be installed at a predetermined position so that the Hall element 18 detects that the magnetic field strength of the inductive component 201 reaches a preset limit. You can.

In a natural state, the protrusion 2213 protrudes outward from the handle 22, and slopes are formed before and after the insertion direction of the protrusion 2213. When inserting the filter 20 into the main body 121, the swing end 2212 can be easily inserted into the avoidance tank 222 due to the slope of the protrusion 2213. That is, it is possible to avoid interfering with the insertion of the swing end 2212 and improve practicality.

Elastic parts (not shown) are further installed in the main body 121, and the elastic parts are brought into contact with the filter 20 to bias the filter 20 in a predetermined direction. Since the elastic component biases the filter 20 in a predetermined direction, the filter 20 can be easily replaced and convenience of use can be improved.

4 to 8, the light emitting structure 12 further includes a front glass 123, and the front glass 123 is installed in the main body 121, and includes a transparent crystal 125 and a lamp 122. It is located in between. When inserting the filter 20 into the main body 121, the filter main body 21 is located on one side of the front glass 123 that is close to the lamp 122, and the filter main body 21 and the front glass ( 123) are arranged in parallel. By installing the front glass 123, it is possible to prevent dust from entering the main body 121 from the light exit port 1211 and affecting the light emission of the lamp 122. In addition, if the front glass 123 is a glass that prevents the incidence of harmful rays such as ultraviolet rays, the user's skin can be further protected through the front glass 123.

The front glass 123 is installed on one side of the transparent crystal 125 that is close to the lamp 122, and the light emitted by the lamp 122 passes through the front glass 123 and the transparent crystal 125. It is then irradiated onto the user's skin. When inserting the filter 20 into the main body 121, the filter main body 21 is located between the transparent crystal 125 and the lamp 122, and the filter main body 21 faces the transparent crystal 125. The light beam that arrives at the transparent crystal 125 is converted into a light beam with a predetermined wavelength by a filter.

A hollow isolation part 1250 is mounted within the case body 10, and the isolation part 1250 seals the area between the transparent crystal 125 and the front glass 123. By closely contacting the transparent crystal 125 and the front glass 123 on both sides of the isolation component 1250, a vacuum in the space between the transparent crystal 125 and the front glass 123 can be secured. The isolation part 1250 seals the space between the transparent crystal 125 and the front glass 123, thereby liquefying the gas on the opposing surface where the front glass 123 and/or the isolation part 1250 face each other. This prevents fog from forming and improves the quality of the emitted light. Additionally, when hot air and cold air meet, the hot air turns into liquid, and there is a risk that this liquid may flow into the circuit board of the hair removal device 1, causing a safety problem. The safety of the hair removal device 1 can be improved by sealing the area between the transparent crystal 125 and the front glass 123 by the isolation part 1250.

The light emitting structure 12 further includes a hollow separator 1214. The separator 1214 is installed on one side of the front glass 123 that is close to the lamp 122, and a concave portion 12141 is formed on one side of the separator 1214 corresponding to the side mounting hole 1212. A step portion 12142 is formed on one side of the separator 1214 away from the concave inlet portion 12141. When inserting the filter 20 into the main body 121, the filter main body 21 is inserted into the main body 121 from the concave inlet portion 12141 and is finally contacted by the step portion 12142. By installing the separator 1214, it is possible to accurately guide the insertion of the filter body 21, determine the position of the filter body 21, and improve the stability of the installed filter 20.

Specifically, the separator 1214 can improve thermal stability by being made of Teflon material.

The light emitting structure 12 further includes a back glass 124, and the back glass 124 is installed on one side of the separator 1214 that is close to the lamp 122. The front glass 123 and the rear glass 124 are in contact with both sides of the separator 1214, and the filter body 21 is connected to the front glass 123, the separator 1214, and the rear glass 124. A space for storage is formed. Since this space is in communication with the outside through the concave inlet 12141 and the side mounting hole 1212, dust enters the main body 121 from the side mounting hole 1212, thereby affecting the light emission of the lamp 122. can be prevented.

The light emitting structure 12 further includes a reflector 1220, the lamp 122 is installed in the reflector 1220, and at least one cutout 12143 is further formed on the separator 1214. The reflector 1220 is in contact with the separator 1214, and a ventilation hole 12144 (as shown in FIG. 8) is formed by the reflector 1220 and the notch 12143. By forming the ventilation hole 12144, the amount of heat inside the light emitting structure 12 can be dissipated.

In order to effectively form the ventilation hole 12144, a plurality of contact convex portions 1221 may be formed on the contact portion of the reflector 1220 that contacts the separator 1214. The border where the contact portion of the reflector 1220 and the cutout 12143 are formed are offset, and the plurality of contact convex portions 1221 formed at intervals are offset from the cutout 12143. As a result, the ventilation area of the ventilation hole 12144 can be increased and the heat dissipation effect can be improved.

Referring to FIG. 9, the filter body 21 includes a filter thin film 211 and a frame 212, the frame 212 is connected to the handle 22, and the filter thin film 211 is within the frame 212. It is installed. Since the frame 212 is installed on the filter body 21, the filter thin film 211 can be easily installed and fixed on the frame 212 at the same time. In addition, it is possible to prevent the filter thin film 211 from being damaged when inserting or withdrawing the filter 20, and to extend the life of the filter thin film 211.

Specifically, the material of the frame 212 is metal, preferably stainless steel. Since metal has excellent heat resistance and decomposition resistance, the filter thin film 211 can be efficiently protected by the metal frame 212.

A gap 213 is formed between the filter thin film 211 and the handle 22, and at least one convex portion 223 is formed on one end of the handle 22 approaching the gap 213, and the convex portion ( 223) is in contact with the filter thin film 211. In this case, heat can be dissipated through the gap 213, and the effectiveness and practicality of use can be improved by the convex portion 223 being in contact with the filter thin film 211.

Since the handle 22 and the frame 212 are covered with a rubber layer, the risk of electric leakage can be reduced and the safety of use can be improved. In addition, since the rubber layer on the handle 22 has good thermal insulation performance, it is possible to avoid giving the user a burning sensation when the user holds the handle 22 and improve the user experience. By forming a rubber layer on the handle 22 and the frame 212 through a two-shot process, structural stability can be secured and the risk of electric leakage can be reduced.

Referring to Figure 10, a reverse insertion prevention structure (Pokayoke structure) is formed on the handle 22. In the reverse insertion prevention structure of this embodiment, at least one pair of opposing sides of the handle 22 may be formed in an asymmetric structure. This structure limits the insertion of the filter 20 in one direction, and avoids affecting the operation of the hair removal device or the function of the filter or causing burns to the user by inserting the filter 20 in the reverse direction.

In the embodiment of the present invention, the width of one side and the width of the other side of the handle 22 on which the guidance component 201 is installed are different, and the shapes of the insertion hole 111 and the side mounting hole 1212 are the handle ( It corresponds to the shape of 22). The width of one side of the handle 22 on which the guiding part 201 is installed may be greater than the width of the other side, or the width of one side of the handle 22 on which the guiding part 201 is installed may be smaller than the width of the other side. . In an embodiment of the present invention, the width D of one side of the handle 22 on which the guiding component 201 is installed is larger than the width d of the other side (as shown in FIG. 10). Due to this structure, the Hall element 18 cannot guide the guiding component 201 by inserting the filter 20 in the reverse direction, and the hair removal device of the present invention cannot be used normally, which affects the user's experience. can be prevented from giving.

When a plurality of Hall elements 18 are installed, information on the inductive component 201 can be recognized through the multiple Hall elements 18. The control system controls the lamp 122 to emit light of various intensities by appropriately controlling the voltage and current in the control circuit based on various information. This makes it possible to obtain light rays with a predetermined wavelength.

11 to 13, in the embodiment of the present invention, two Hall elements 18 are installed in the case body 10, and the two Hall elements 18 are a Hall element 18a and a Hall element 18. The element 18b, and the handle 22 includes a first position (A) and a second position (B). When inserting the filter 20 into the main body 121, the first position A and the second position B correspond to the Hall element 18a and Hall element 18b, respectively. Depending on whether the guiding component 201 is installed in the first position (A) and the second position (B), the present invention includes the following three cases. In the first case, the guiding part 201 is installed in the first position (A), and the guiding part 201 is not installed in the second position (B). A whitening effect can be achieved by the filter 20 having this structure. In this case, the Hall element 18a can detect a magnetic field strength of a preset threshold, send a start signal to the control system, and at the same time form a light beam suitable for whitening (as shown in Figure 11). In the second case, the guiding component 201 is installed in the second position (B), and the guiding component 201 is not installed in the first position (A). The effect of removing acne can be achieved by the filter 20 having this structure. In this case, the Hall element 18b can detect the magnetic field strength of the preset threshold and send a start signal to the control system, while at the same time forming a light beam suitable for removing acne (as shown in Fig. 11). In the third case, the guiding components 201 are installed at the first position A and the second position B, respectively. The hair loss effect can be achieved by the filter 20 having this structure. In this case, the Hall element 18a and the Hall element 18b can detect the magnetic field strength of the preset limit and form a light beam suitable for hair removal at the same time as sending a start signal to the control system (shown in Figure 13 Same as bar).

14 to 16, a Peltier element mounting hole 1215 is further formed in the main body 121, and the case main body 10 further includes a cooling module 19. The cooling module 19 can lower the temperature of the transparent crystal 125 by contacting the transparent crystal 125 through the Peltier element mounting hole 1215.

The cooling module 19 includes a Peltier element 191, a heat transfer plate 192, a heat transfer pipe 193, and a radiator 194. One side (cooling side) of the Peltier element 191 is in contact with the transparent crystal 125 after passing through the Peltier element mounting hole 1215, and the other side of the Peltier element 191 is connected to the heat transfer plate 192 and the heat transfer pipe ( 193) and are sequentially connected to the radiator (194). The transparent crystal 125 is cooled by the cooling surface of the Peltier element 191, and the heat generated is dissipated by the heat transfer plate 192, heat transfer pipe 193, and radiator 194.

The case body 10 further includes a temperature sensitive module 195, and the temperature sensitive module 195 penetrates the light emitting structure 12 and is then contacted to the transparent crystal 125.

A temperature measuring hole 1216 is further formed in the main body 121, and one end of the temperament sensitive module 195 is inserted into the temperature measuring hole 1216 and is in contact with the transparent crystal 125. The other end of the temporature sensitive module 195 is electrically connected to the button PCBA 16, and the temporature sensitive module 195 is linked to the cooling module 19 through the button PCBA 16.

The temperament sensitive module 195 includes a first thermistor 196 and heat transfer silicone grease 197. One side of the heat transfer silicone grease 197 is in contact with the transparent crystal 125, and the other side of the heat transfer silicone grease 197 covers the first thermistor 196. By installing the heat transfer silicone grease 197, the temperature change of the transparent crystal 125 can be accurately detected.

The temperature of the transparent crystal 125 may increase by irradiation of light from the lamp 122, and the temperature of the transparent crystal 125 may decrease by cooling of the cooling module 19. The lamp 122 emits light intermittently, and the time for intermittently emitting light is determined by the user pressing the light emitting button 15, and the temperature of the transparent crystal 125 is lowered through the cooling module 19. It takes a certain amount of time. These two times cannot be easily matched, and the heating efficiency and cooling efficiency are also different. It is necessary to operate the cooling module 19 for a long time when using the hair removal device to avoid causing burns to the user due to high temperature. If the temperature of the hair removal device drops excessively by operating the cooling module 19 for a long time, the user's comfort may be affected. The resistance threshold of a temperature suitable for comfort can be set in advance by the first thermistor 196. By stopping the cooling module 19 when the temperature is low and activating the cooling module 19 when the temperature is high, the temperature of the transparent crystal 125 can be controlled to a temperature suitable for comfort. In other words, the temperature in contact with the user's skin can be adjusted to a temperature suitable for comfort.

The first thermistor 196 may be a thermistor with a positive temperature coefficient. In this case, the resistance of the first thermistor 196 increases as the temperature rises. The first thermistor 196 and the cooling module 19 can be connected in parallel and a small resistance threshold can be set. When the temperature is lower than the critical temperature corresponding to the resistance threshold, the current in the circuit where the cooling module 19 is located is too small to start the cooling module 19. That is, the cooling module 19 is in a stopped state, and when the temperature rises, the cooling module 19 can be started again. The set resistance threshold corresponds to the optimal temperature, and the actual temperature may vary above and below the optimal temperature. The first thermistor 196 may be a thermistor with a negative temperature coefficient. In this case, the resistance of the first thermistor 196 decreases as the temperature increases. The first thermistor 196 and the cooling module 19 can be connected in series and a large resistance threshold can be set. When the temperature is lower than the critical temperature corresponding to the resistance threshold, the resistance connected to the circuit where the cooling module 19 is located is very large, and the current in the circuit where the cooling module 19 is located is very small, so the cooling module 19 cannot be started. I can't. That is, the cooling module 19 is in a stopped state, and when the temperature rises, the cooling module 19 can be restarted. The set resistance threshold corresponds to the optimal temperature, and the actual temperature may vary above and below the optimal temperature.

When realizing a certain function, it is necessary to bring the first thermistor 196 close to the transparent crystal 125 that leads to the first thermistor 196. That is, it is necessary to move the first thermistor 196 away from the button PCBA 16. The first thermistor 196 and the button PCBA 16 are electrically connected by a wire, and the wire between the first thermistor 196 and the button PCBA 16 is not supported, so (the first thermistor 196 and the button PCBA (As the distance between (16) increases), there is a risk that the safety and stability of the wire between the first thermistor (196) and the button PCBA (16) may decrease. In the present invention, a connection circuit board 161 is further provided, and the first thermistor 196 and the button PCBA 16 are connected through this connection circuit board 161. An integrated circuit is formed within the connection circuit board 161, and the integrated circuit inside can be stably supported through the connection circuit board 161, thereby solving the problem of poor safety and stability of the internal circuit of the conventional hair loss device. there is.

The light emitting structure 12 further includes a pressure plate 126, which covers the conductive region 1612. A portion of the pressure plate 126 covering the conducting area 1612 is located in the gap 172. The shape of the pressure plate 126 corresponds to the shape of the surface of a part of the main body 121. By approaching the conductive area 1612 to the surface of the main body 121, tightness can be improved and the stability of the connection circuit board 161 can be increased. Additionally, by locating a portion of the pressure plate 126 in the gap 172, the space inside the hair removal device can be sufficiently utilized.
