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.

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 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.

This can prevent the filter function of the filter 20 from being affected by the user's fingers coming into contact with the filter body 21.

The guiding part 201 may be installed in a hidden state on the handle 22 by glue wrapping, plastic capsulation, etc., or the guiding part 201 may be inserted into a storage tank formed on the handle 22. . As a result, the filter 20 on which the inductive component 201 is installed can be easily inserted into or extracted from the case body 10, and the stability of the inductive component 201 can be improved.

You can avoid giving .

The fixing structure 221 can be formed on the same side or on both sides of the guiding component 201. The fixing structure 221 can be formed at any position of the inductive component 201 as long as it does not affect the mounting of the inductive component 201. In an embodiment of the present invention, the fixing structure 221 is formed on both sides of the guiding component 201.

An avoidance tank 222 is further formed at a location of the handle 22 corresponding to the fixing structure 221. The fixed structure 221 includes a fixed end 2211 and a swinging end 2212, the fixed end 2211 is connected to the inner wall of the avoiding tank 222, and the swinging end 2212 supports the avoiding tank 222. heading towards A protrusion 2213 is formed on one side of the swing end 2212 away from the avoidance tank 222. 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.

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.

The case body 10 further includes a connection circuit board 161, and the Hall element 18 and the first thermistor 196 are connected to the control circuit of the button PCBA 16 by the connection circuit board 161.

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 entire connection circuit board 161 may be a flexible circuit board, or a part of the connection circuit board 161 may be a flexible circuit board and the other part may be a rigid circuit board. When the entire connection circuit board 161 is a flexible circuit board, the connection circuit board 161 can be changed to an arbitrary shape depending on the size of the space inside the hair removal device and the shape of the parts near the connection circuit board 161. This allows sufficient use of the space inside the hair removal device. When a part of the connection circuit board 161 is a flexible circuit board and the other part is a rigid circuit board, by changing the flexible circuit board into a predetermined shape, the space inside the hair removal device can be sufficiently utilized and practicality can be improved.

The Hall element 18 is electrically connected to the fixed area 1613, and the insertion direction of the fixed area 1613 and the filter 20 is parallel.

The connection area 1611 is formed to bend toward the main control PCBA 17, and a first concave portion 1614 is formed by the connection area 1611, and some of the electronic components 171 on the main control PCBA 17 is received within the first concave portion 1614.

By connecting the connection area 1611 and the conduction area 1612, an included angle θ (θ in FIG. 14) is formed between the connection area 1611 and the conduction area 1612. The range of the included angle θ is 45° to 90°, and the preferred included angle θ is 90°, so that the storage space of the first concave portion 1614 can be increased.

The curvature direction of the connection area 1611 and the curvature direction of the conduction area 1612 are perpendicular, and the order in which the first recess 1614 and the second recess 1615 are formed is the main control PCBA 17 and the light emitting structure ( 12) corresponds to the order in which it was formed.

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.

The conductive area 1612 can be protected by the material of the pressure plate 126 being moisture proof foam cotton.

A second thermistor 162 is installed on the button PCBA 16, and the second thermistor 162 is inserted into the heat dissipation structure 13 to detect the internal temperature of the heat dissipation structure 13.

The heat dissipation structure 13 includes an air guide structure 131, and a mounting hole 173 is formed at a position of the main control PCBA 17 corresponding to the air guide structure 131, and corresponds to the second thermistor 162.

The air guide structure 131 is inserted into the mounting hole 173 and is brought into contact with the button PCBA 16, and the second thermistor 162 is inserted into the insertion hole 1311 to ensure ventilation within the air guide structure 131. Measure the temperature. If the temperature within the hair removal device 1 is too high, each component within the hair removal device 1 ages rapidly and the lifespan of each component is shortened, which may increase safety risks. When the light emitting structure 12 emits light, heat is generated, and this heat is dissipated by the ventilation structure. The present invention sets a threshold for the amount of heat in advance, and starts a program that turns off the hair removal device 1 when the second thermistor 162 in the ventilation structure detects that the amount of heat in the light emitting structure 12 exceeds the preset threshold. You can do it. This allows the hair loss device 1 of the present invention to operate within a predetermined temperature.
