Description

Technical Field

[0001] The present invention relates to a heating rod, a hanger device, and a perm module including the same, and more particularly, to a heating rod, a hanger device, and a perm module including the same, to which a terminal separation structure is applied.

Background Art

[0002] Generally, methods for perming hair (also called "curling") include a perm method of applying a perm agent to the hair, a setting method of directly applying heat to the hair to create waves without using a perm agent, and a mixed method of applying a perm agent to the hair and then applying heat to perm the hair. Here, in order to apply heat to the hair for perming, a heating rod (Korean Registered Patent Publication No. 10-0405257, announced on November 12, 2003) that is connected to a perm device and generates heat when power is applied is utilized.

[0003] However, since the electrical terminals of existing heating rods are arranged only on one side of the heating rod body, there has been a problem that one end of the heating rod is further heated and the load on the electrical terminals is increased.

[0023] FIG. 38 is an overall perspective view of a perm module according to an embodiment of the present invention.

[0024] As shown in Figure 1, a perm module 10 according to one embodiment of the present invention is a perm module that transmits heat to hair by electrical energy transmitted from a perm main body for the purpose of perming, and may include a hanger device 200 connected to the perm main body, and an electric heating rod 100 that is detachable from the hanger device 200 and generates heat based on electrical energy transmitted from the hanger device 200 while remaining connected to the hanger device 200.

[0025] A perm device is a device used to support hair and release heat when performing treatments such as perms, straightening, and coloring.

[0026] The perm device may include a support part (not shown) that stands upright on the ground, a perm main body (not shown) supported by the support part so as to be separated from the ground, an electric heating rod 100 that forms an area where hair is wrapped and releases heat by electrical energy, and a plurality of hanger devices 200 to which the electric heating rod 100 is attached and detached and electrically connected to the perm main body so as to transmit electrical energy to the electric heating rod 100.

[0027] The perm stylist wraps the hair around a 100mm electric rod, and then applies hair dye or perm solution to the hair.

[0028] Subsequently, the hanger device 200 is connected to the heating rod 100 so that electrical energy is transmitted to the heating rod 100 via the perm machine body and the hanger device 200.

[0029] As a result, heat is released from the electric heating rod 100 and applied to the hair.

[0030] The structure of the electric heating rod 100 and the hanger device 200 will be described in detail below.

[0031] Figure 2 is an exploded perspective view of the electric heating rod of a perm module according to one embodiment of the present invention, and Figure 3 is an enlarged view of part A in Figure 2.

[0032] As shown in Figures 2 and 3, the electric heating rod 100 according to one embodiment of the present invention may include a housing portion 110 having an outer surface that provides a region on which hair is wrapped and an inner surface that has a predetermined space, which is a receiving space; a heating portion 120 disposed in the receiving space that releases heat by transmitted electrical energy; a temperature sensor portion 130 disposed in the receiving space that senses the temperature at least one point in the receiving space and the housing portion 110; a power terminal portion 140 coupled to the housing portion 110 and electrically connected to the heating portion 120 to receive electrical energy from the outside and transmit it to the heating portion 120; and a sensor terminal portion 150 coupled to the housing portion 110 and electrically connected to the temperature sensor portion 130.

[0033] Furthermore, the electric heating rod 100 may further include a rod insulating portion 160 positioned between the power terminal portion 140 and the sensor terminal portion 150 in the width direction of the housing portion 110, so as to insulate the power terminal portion 140 and the sensor terminal portion 150 from each other.

[0034] Furthermore, the electric heating rod 100 may further include a rod support portion 170 that supports the heating portion 120 such that the heating portion 120 is located at one point in the housing space separated from the inner surface of the housing portion 110.

[0035] The housing portion 110 may have a hollow structure in the longitudinal direction and may include a main housing portion 111 on its outer surface around which hair is wrapped, and cover portions 112 that are connected to both ends of the main housing portion 111.

[0036] The main housing portion 111 may have an internal storage space S111.

[0037] The main housing portion 111 is cylindrical and may have a hollow core in the longitudinal direction.

[0038] Both ends of the main housing portion 111 may be open, and the hollow ends of the main housing portion 111 may communicate with the outside.

[0039] Hair is wrapped around the outer surface of the main housing section 111 and adheres tightly to it.

[0040] The main housing portion 111 may be made of a ceramic material, but the present invention is not limited thereto, and the material of the main housing portion 111 can be varied in a manner that is obvious to an ordinary engineer.

[0041] The cover portion 112 may include a cover body portion 112a into which the main housing portion 111 is fastened and into which a cover hole h112 into which the sensor terminal portion 150 is inserted is formed, and a cover projection portion 112b that protrudes from the rear surface of the cover body portion 112a and surrounds the sensor terminal portion 150.

[0042] Furthermore, the cover portion 112 may further include a first cover support portion 112c that is spaced apart from the cover projection portion 112b in the diametrical direction of the cover body portion 112a and protrudes from the cover body portion 112a, a second cover support portion 112d that protrudes from around the cover body portion 112a, and a third cover support portion 112e that is positioned between the first cover support portion 112c and the second cover support portion 112d and protrudes from the cover body portion 112a.

[0043] The cover body portion 112a may be disc-shaped.

[0044] However, the shape of the cover body portion 112a can be varied in a manner that is obvious to an ordinary engineer.

[0045] One side of the cover body 112a may be recessed to form a cover recess P112 (see Figure 6) so that the other end of the hanger leg 220 can be inserted.

[0046] A cover hole h112 is formed on the bottom surface of the cover recess P112.

[0047] Furthermore, the side surface of the cover recess P112 may be formed to be inclined in the direction of the cover hole h112.

[0048] A cover hole h112, which is a predetermined hole, may be formed in the center of the cover body portion 112a in the longitudinal direction.

[0049] The sensor terminal section 150, the rod insulation section 160, and the power terminal section 140 may be inserted into the cover hole h112 in that order.

[0050] The cover projection 112b may protrude from the rear surface of the cover body 112a.

[0051] The cover projection 112b may protrude in a cylindrical shape so as to surround the cover hole h112.

[0052] The inner surface of the cover projection 112b may be spaced apart from the sensor terminal portion 150 so that a portion of the cover body portion 112a can absorb impact during the connection process between the hanger device 200 and the heating rod 100.

[0053] The first cover support portion 112c may protrude from the rear surface of the cover body portion 112a, and the cover protrusion portion 112b may be cylindrical in shape to surround it.

[0054] The end of the rod support portion 170 is connected to and supported by the rear surface of the first cover support portion 112c.

[0055] The first fastening support portion and the rod support portion 170 are connected to each other by fastening members (bolts).

[0056] The second cover support portion 112d may protrude from around the cover body portion 112a toward the main housing portion 111.

[0057] The outer surface of the second cover support portion 112d may have irregularities formed on it to improve the user's grip efficiency.

[0058] The third cover support portion 112e is positioned between the first cover support portion 112c and the third cover support portion 112e and may protrude from the rear surface of the cover body portion 112a toward the main housing portion 111.

[0059] The end of the main housing portion 111 may be retracted between the first cover support portion 112c and the second cover support portion 112d.

[0060] The end of the main housing portion 111 may be fixed to the rear surface of the third cover support portion 112e.

[0061] The heating element 120 is made of a resistive material and releases heat based on electrical energy.

[0062] The temperature sensor unit 130 is positioned in the housing space and senses the temperature at at least one point in the housing space and the housing unit 110.

[0063] As an example, the temperature sensor unit 130 is fixed to the inner surface of the housing unit 110, and the temperature is detected by the change in electrical strength due to the change in resistance caused by the temperature change.

[0064] However, the fixing position of the temperature sensor unit 130 can be varied in various ways at a level that is obvious to an ordinary engineer.

[0065] As an example, the temperature sensor unit 130 is fixed to the rod support unit 170.

[0066] The power terminal section 140 may be made of a conductive material that conducts electricity.

[0067] The power terminal section 140 may be located inside the sensor terminal section 150.

[0068] The power terminal section 140 may include a first power terminal section 141 to which the heating section 120 is physically and electrically connected, and a second power terminal section 142 extending from the first power terminal section 141 in the longitudinal direction of the first power terminal section 141.

[0069] The first power terminal section 141 may be cylindrical.

[0070] However, the shape of the first power terminal section 141 can be varied in a manner that is obvious to an ordinary engineer.

[0071] A second power terminal portion 142 may be connected to one end of the first power terminal portion 141, and the other end of the first power terminal portion 141 may be recessed.

[0072] A portion of the temperature sensor portion 130 is inserted into the recessed portion of the first power terminal portion 141, thereby electrically connecting the temperature sensor portion 130 and the power terminal portion 140.

[0073] The second power terminal section 142 may also be cylindrical.

[0074] However, the shape of the second power terminal section 142 can be varied in a manner that is obvious to an ordinary engineer.

[0075] The width (diameter) of the second power terminal section 142 may be smaller than the width (diameter) of the first power terminal section 141.

[0076] The second power terminal section 142 may be electrically connected by contact with the main terminal section 230 of the hanger device 200, which will be described later.

[0077] The rod insulating portion 160 may be made of an insulator.

[0078] The rod insulating portion 160 forms a hollow on the inside in the longitudinal direction of the housing portion 110 and is positioned inside the sensor terminal portion 150.

[0079] The rod insulating portion 160 may include a first rod insulating portion 161 having a hollow interior in the longitudinal direction and a second rod insulating portion 162 having a hollow interior in the longitudinal direction and extending from one end of the first rod insulating portion 161.

[0080] The width (diameter) of the first rod insulating portion 161 may be larger than the width (diameter) of the second rod insulating portion 162.

[0081] The hollow of the first rod insulating portion 161 and the hollow of the second rod insulating portion 162 are in communication with each other, allowing the second power terminal portion 142 to be inserted.

[0082] The rod insulating section 160 performs the function of electrically isolating the power terminal section 140 and the sensor terminal section 150.

[0083] The sensor terminal portion 150 may be made of an electrically conductive material.

[0084] The sensor terminal portion 150 may be connected to the side end of the housing portion 110 such that one end of the sensor terminal portion 150 is located in the housing space and the other end of the sensor terminal portion 150 is located outside the housing portion 110.

[0085] The sensor terminal portion 150 may have a hollow space formed inward along the length of the housing portion 110.

[0086] The sensor terminal portion 150 may include a first sensor terminal portion 151 having a hollow in the longitudinal direction and a second sensor terminal portion 152 having a hollow inward in the longitudinal direction and extending from one end of the first sensor terminal portion 151.

[0087] The width (diameter) of the first sensor terminal portion 151 may be larger than the width (diameter) of the second sensor terminal portion 152.

[0088] The hollow of the first sensor terminal portion 151 and the hollow of the second sensor terminal portion 152 are in communication with each other, and the second power supply terminal portion 142 can be inserted into them.

[0089] The sensor terminal portion 150 may have a soldering portion P151 formed in which one end of the sensor terminal portion 150 is recessed and a part of the temperature sensor portion 130 is welded and connected.

[0090] In other words, a portion of the outer surface of the other end of the first sensor terminal portion 151 is recessed with a step to form the soldering portion P151.

[0091] The wire portion of the temperature sensor unit 130 is soldered to the soldering section P151 and fixed in place.

[0092] The soldering portion P151 provides more effective fixation of the soldered portion and effectively prevents damage to the soldering portion P151 during the disassembly and assembly process of the electric heating rod 100.

[0093] The first power terminal section 141 is positioned between the rod support sections 170, and a portion of the heating section 120 is inserted into the recessed portion of the first power terminal section 141, making contact and connection.

[0094] The second power terminal portion 142 may be formed with a step between it and the first power terminal portion 141, and the second power terminal portion 142 may be inserted into the inner hollow of the rod insulating portion 160.

[0095] The first rod insulating portion 161 may be supported by contacting one surface of the first power terminal portion 141, which is the stepped portion between the first power terminal portion 141 and the second power terminal portion 142.

[0096] The rod insulating portion 160 is inserted into the hollow of the sensor terminal portion 150. In this state, it is externally fitted to the power terminal portion. It may be placed.

[0097] The outer surface of the first rod insulating portion 161 may be in contact with the inner surface of the first sensor terminal portion 151.

[0098] The outer surface of the second rod insulating portion 162 may be in contact with the inner surface of the second sensor terminal portion 152.

[0099] The second sensor terminal section 152 is inserted into the cover hole h112.

[0100] The first sensor terminal portion 151 and the second sensor terminal portion 152 are formed with a step between them, and one surface of the first sensor terminal portion 151, which is the step portion between the first sensor terminal portion 151 and the second sensor terminal portion 152, is in contact with and supported by the cover body portion 112a adjacent to the cover hole h112.

[0101] A portion of the second sensor terminal portion 152 may be positioned on the cover hole h112, and the remaining portion of the second sensor terminal portion 152 may be located on one side of the cover body portion 112a, which is outside the housing space.

[0102] In other words, the second sensor terminal portion 152 protrudes from the cover body portion 112a in one direction.

[0103] This solves the problem of the electric heating rod 100 causing the air to expand due to heating, which then disengages the connection between the electric heating rod 100 and the hanger device 200.

[0104] The outer surface of the first sensor terminal portion 151 may be spaced apart from the inner surface of the cover protrusion 112b.

[0105] The sensor terminal portion 150 may be fixed to the cover body portion 112a with an adhesive material.

[0106] Similarly, the rod insulating portion 160, the sensor terminal portion 150, and / or the main terminal portion 230 may be bonded and fixed to each other with an adhesive substance.

[0107] However, the present invention is not limited thereto, and the methods of joining and fixing can be varied in many ways at a level that is obvious to an ordinary person.

[0108] Each of the cover portion 112, to which the power terminal portion 140 and the sensor terminal portion 150 are fastened, may be connected to both ends of the main housing portion 111, respectively.

[0109] Although the explanation has been based on the cover portion 112, the present invention is not limited to this.

[0110] Figure 4 is an exploded perspective view of a hanger device for a perm module according to one embodiment of the present invention, and Figure 5 is an enlarged perspective view of portion A in Figure 4.

[0111] As shown in Figures 4 and 5, a hanger device 200 according to one embodiment of the present invention is a hanger device 200 that, as a component of a perm device, is connected to and supports a heating rod 100 so as to be separated from the ground, and may include a hanger body 210, a hanger leg 220 connected to the hanger body 210 so as to rotate one end of the hanger body 210 with respect to the hanger body 210, a main terminal 230 located at the other end of the hanger leg 220 to which the power terminal 140 of the heating rod 100 is connected, and an auxiliary terminal 240 located at the other end of the hanger leg 220 to which the sensor terminal 150 of the heating rod 100 is connected.

[0112] Furthermore, the hanger device 200 may further include a wire module 250 that physically and electrically connects the perm body and the hanger body 210 to each other.

[0113] Furthermore, the hanger device 200 may further include a hanger insulating portion 260 positioned between the main terminal portion 230 and the auxiliary terminal portion 240 so that the main terminal portion 230 and the auxiliary terminal portion 240 are insulated from each other.

[0114] The hanger body 210 may include a body housing 211 that provides a predetermined space inside, a body circuit board 212 disposed inside the body housing 211 and electrically connected to the wire module 250 for electrical processing, and a switch 213 disposed on the outer surface of the body housing 211 and electrically connected to the body circuit board 212 to determine whether the electrical energy of the wire module 250 is transferred to the hanger legs 220.

[0115] The hanger legs 220 are connected to the hanger body 210 with two legs facing each other.

[0116] The following explanation will be based on one hanger leg 220, but the present invention is not limited to this, and the explanation of the hanger leg 220 may be omitted if it is redundant.

[0117] The hanger leg portion 220 may include a leg housing portion 221, one end of which is rotatably connected to the main body housing portion 211, and a leg base portion 222, which is positioned inside the leg housing portion 221 and electrically connected to the main body base portion 212.

[0118] One end of the leg housing portion 221 is rotatably connected to the main body housing portion 211, and the other end of the leg housing portion 221 is equipped with a main terminal portion 230 and an auxiliary terminal portion 240.

[0119] The leg housing portion 221 may have the shape of a "┓" or a mirror image of a "┓".

[0120] However, the shape of the leg housing portion 221 can be varied in a manner that is obvious to an ordinary engineer.

[0121] The leg housing portion 221 can be manufactured by an insert injection process while the leg base portion 222 is still inserted into the mold.

[0122] Therefore, in Figure 4, the leg housing portion 221 may be shown in parallel with the leg base portion 222 without being disassembled.

[0123] The leg base portion 222 may include a leg base body portion 222a, one end of which is electrically connected to the main base portion 212; a first leg base projection portion 222b, which protrudes from the other end of the leg base body portion 222a; and a second leg base projection portion 222c, which is spaced apart from the first leg base projection portion 222b and protrudes from the other end of the leg base body portion 222a.

[0124] The leg base plate body portion 222a can be electrically connected to the main base plate portion 212.

[0125] At least a portion of the other end of the leg base body portion 222a is made of a conductive material so that the main terminal portion 230 can be physically and electrically connected to it.

[0126] The auxiliary terminal portion 240 is inserted between the first leg substrate protrusion 222b and the second leg substrate protrusion 222c.

[0127] At least a portion of the first leg substrate protrusion 222b and the second leg substrate protrusion 222c are made of a conductive material and can be physically and electrically connected to the auxiliary terminal portion 240.

[0128] The connecting portion between the first leg base projection 222b and the leg base body portion 222a can be recessed to form a predetermined space.

[0129] Furthermore, the connecting portion between the second leg substrate protrusion 222c and the leg substrate main body 222a can be recessed to form a predetermined space.

[0130] Such a space can enhance the ease of assembly and disassembly of the auxiliary terminal section 240.

[0131] At least a portion of the main terminal portion 230 may be made of a conductive material.

[0132] The main terminal section 230 may include a main terminal body section 231 electrically connected to the hanger leg section 220, a main terminal moving section 232 that is movable relative to the main terminal body section 231, electrically connected to the main terminal body section, into which the power terminal section 140 of the heating rod 100 is inserted, and a terminal elastic section 233 that pressurizes the main terminal moving section 232 in the direction toward the power terminal section of the heating rod 100.

[0133] The main terminal body portion 231 may include a first main terminal body portion 231a having a shape that opens in the other direction, and a second main terminal body portion 231b that protrudes from one end of the first main terminal body portion 231a and is secured to the other end of the leg base body portion 222a.

[0134] The first main terminal body portion 231a is cylindrical and forms a predetermined space inside, and the internal space can be connected to the outside in other directions.

[0135] The width (diameter) of the second main terminal body 231b may be smaller than the width (diameter) of the first main terminal body 231a.

[0136] The second main terminal body 231b can directly contact the conductive material of the leg base body 222a, thereby electrically mediating between the leg base body 222a and the power terminal 140.

[0137] The main terminal moving part 232 is inserted into the inner space of the main terminal body part 231.

[0138] The main terminal movement portion 232 may include a first main terminal movement portion 232a that is recessed in the other direction and into which the second power terminal portion 142 is inserted, and a second main terminal movement portion 232b that extends in one direction from the first main terminal movement portion 232a and into which the terminal elastic portion 233 is externally fitted.

[0139] The first main terminal moving part 232a can come into contact with the inner surface of the main terminal body part 231.

[0140] The first main terminal moving part 232a can slide along the main terminal body part 231 in one direction and in the other.

[0141] The terminal elastic portion 233 is made of an elastic material and is fitted onto the second main terminal moving portion 232b, thereby applying pressure to the second main terminal moving portion 232b.

[0142] This effectively prevents the electric heating rod 100 from unintentionally separating from the hanger device 200 while the electric heating rod 100 and the hanger device 200 are connected.

[0143] For example, the terminal elastic portion 233 may be a coil spring.

[0144] However, this is not limited to the above, and the types of terminal elastic parts 233 can be varied in a way that is obvious to an average engineer.

[0145] The terminal elastic portion 233 is positioned inside the first main terminal moving portion 232a while remaining externally fitted to the second main terminal moving portion 232b.

[0146] The hanger insulating portion 260 may include a first hanger insulating portion 261 having a hollow interior in the longitudinal direction and a second hanger insulating portion 262 having a hollow interior in the longitudinal direction and extending from the other end of the first hanger insulating portion 261.

[0147] The hanger insulation portion 260 may have a shape that is open in the longitudinal direction on both sides.

[0148] As an example, the first hanger insulating portion 261 and the second hanger insulating portion 262 may each have a cylindrical shape.

[0149] However, the shapes of the first hanger insulating portion 261 and the second hanger insulating portion 262 can be varied in a manner that is obvious to an ordinary engineer.

[0150] The diameter of the first hanger insulating portion 261 may be larger than the diameter of the second hanger insulating portion 262.

[0151] Furthermore, the inner diameter of the first hanger insulating portion 261 may be larger than the inner diameter of the second hanger insulating portion 262.

[0152] The main terminal body portion 231 is positioned in the inner space of the first hanger insulating portion 261, and the inner surface of the first hanger insulating portion 261 and the outer surface of the main terminal body portion 231 can come into contact with each other.

[0153] If the second power terminal portion 142 is not connected to the first main terminal moving portion 232a, one surface of the second hanger insulating portion 262 can come into contact with the first main terminal moving portion 232a due to the terminal elastic portion 233.

[0154] The hanger insulating portion 260 has an insulating space S261 on its inside where the main terminal portion 230 is located, and a second insulating space S262 where the power terminal portion 140 of the heating rod 100 can be located in order to be connected to the main terminal portion 230.

[0155] More specifically, the first hanger insulating portion 261 has a first insulating space S261 formed inside in which the main terminal portion 230 is arranged, and the second hanger insulating portion 262 has a second insulating space S262 formed inside in which the second power terminal portion 142 is inserted.

[0156] Here, the width (diameter) of the second insulating space S262 may be formed to be even larger than the width (diameter) of the power terminal portion 140 (second power terminal portion 142) of the heating rod 100.

[0157] This allows for fine adjustment of the displacement of the heating rod 100 while maintaining its connection to the hanger device 200, in response to factors such as the patient's movements during the treatment, the wire module 250, and the strength of the hair.

[0158] The auxiliary terminal section 240 may be located outside the main terminal section 230, at a distance from it.

[0159] The auxiliary terminal portion 240 may include a first auxiliary terminal portion 241 having a hollow interior in the longitudinal direction and a second auxiliary terminal portion 242 having a hollow interior in the longitudinal direction and extending from the other end of the first auxiliary terminal portion 241.

[0160] The auxiliary terminal portion 240 may have a shape that is open in the longitudinal direction on both sides.

[0161] As an example, the first auxiliary terminal portion 241 and the second auxiliary terminal portion 242 may each have a cylindrical shape.

[0162] However, the shapes of the first auxiliary terminal portion 241 and the second auxiliary terminal portion 242 can be varied in a manner that is obvious to an ordinary engineer.

[0163] The diameter of the first auxiliary terminal portion 241 may be larger than the diameter of the second auxiliary terminal portion 242.

[0164] Furthermore, the inner diameter of the first auxiliary terminal portion 241 may be larger than the inner diameter of the second auxiliary terminal portion 242.

[0165] The inner surface of the first auxiliary terminal portion 241 may be in contact with the outer surface of the first hanger insulating portion 261.

[0166] The inner surface of the second auxiliary terminal portion 242 may be in contact with the outer surface of the second hanger insulating portion 262.

[0167] One end of the auxiliary terminal portion 240 may have a width greater than the width of one end of the sensor terminal portion 150 of the heating rod 100, so as to contact one end of the sensor terminal portion 150 of the heating rod 100.

[0168] Specifically, the width (diameter) of the second auxiliary terminal portion 242 may be larger than the width (diameter) of the second sensor terminal portion 152.

[0169] Furthermore, the inner hollow width (diameter) of the second auxiliary terminal portion 242 may be larger than the width (diameter) of the second sensor terminal portion 152.

[0170] As a result, even if the displacement of the heating rod 100 is finely adjusted, the electrical connection between the auxiliary terminal section 240 and the sensor terminal section 150 is not released.

[0171] The first auxiliary terminal portion 241 can be inserted into and connected to the first leg substrate protrusion 222b and the second leg substrate protrusion 222c.

[0172] The first auxiliary terminal portion 241 can be electrically connected to the first leg substrate protrusion portion 222b and the second leg substrate protrusion portion 222c.

[0173] The following describes in detail the process of connecting the electric heating rod 100 and the hanger device 200.

[0174] Figure 6 is a cross-sectional view of the portion where the electric heating rod and hanger device are connected according to one embodiment of the present invention, and Figure 7 is a diagram illustrating the function of the cover projection of the electric heating rod according to one embodiment of the present invention.

[0175] As shown in Figures 6 and 7, the sensor terminal portion may be arranged such that at least a portion of it is separated from the power terminal portion in the width direction of the housing portion.

[0176] Specifically, the second power supply terminal section 142 is positioned in the hollow interior of the second sensor terminal section 152, and the second sensor terminal section 152 and the second power supply terminal section 142 are spaced apart from each other in the width direction (diameter direction) of the housing section 110.

[0177] The normal vector of region A10 of the sensor terminal portion that the auxiliary terminal portion contacts is a vector that includes the length direction of the auxiliary terminal portion and the length direction of the main terminal portion.

[0178] Preferably, the normal vector of the region A10 of the sensor terminal portion that the auxiliary terminal portion contacts may be in the longitudinal direction of the auxiliary terminal portion 240 / the longitudinal direction of the main terminal portion 230.

[0179] In this way, by presenting a new power terminal structure in which the sensor terminal and power terminal are physically separated from each other, deviating from the existing earphone terminal connection method, it is possible to present an electrical circuit structure that draws in electrical energy from the heating rod side and releases electrical energy to the other side of the heating rod.

[0180] The process of connecting the electric heating rod and the hanger device will be explained in detail below.

[0181] The hanger legs can be spread out relative to the main body of the hanger.

[0182] With the hanger legs spread out, the heating rod is positioned between the hanger legs, after which the hanger legs can be closed.

[0183] The other end of the leg housing portion 221 is shaped to protrude in another direction, allowing it to be inserted into the cover recess portion P112.

[0184] At this time, the second power terminal portion 142 is inserted inside the second hanger insulating portion 262 located at the other end of the leg housing portion 221, and the second power terminal portion 142 can be inserted into the recessed space of the first main terminal moving portion 232a.

[0185] At this time, the first main terminal moving part 232a moves in one direction while the terminal elastic part 233 can contract.

[0186] The terminal elastic portion 233 can prevent the heating rod from separating from the leg housing portion 221 by applying pressure to the main terminal moving portions 232a and 232b in the direction toward the second power terminal portion 142.

[0187] When the power terminal and the main terminal come into contact with each other, the auxiliary terminal and the sensor terminal can also come into contact with each other.

[0188] Specifically, one side of the second sensor terminal portion 152 and the other side of the second auxiliary terminal portion 242 can come into contact with each other.

[0189] The other end of the leg housing portion 221 may be spaced apart from the cover recess portion P112.

[0190] This prevents the heating rod 100 from being separated from the hanger device 200 by the expansion of the air between the leg housing 221 and the cover body 112a as the heating rod 100 is heated.

[0191] The air present between the leg housing portion 221 and the cover body portion 112a is heated and expanded, and then discharged to the outside through the space between the cover recess portion P112 and the leg housing portion 221.

[0192] As shown in Figure 7, during the process of connecting the hanger device and the heating rod, the leg housing portion 221 rotates and expands relative to the hanger housing portion, then closes as it is inserted into the cover recess portion P112, so that the main terminal portions 231, 232, 233 and the auxiliary terminal portions 241, 242 can contact the power terminal portions 141, 142 and the sensor terminal portions 151, 152, respectively.

[0193] Here, the force that closes the leg housing portion 221 can strike the power terminal portions 141, 142 and the sensor terminal portions 151, 152, thereby applying an external force to the power terminal portion 140 and the sensor terminal portion 150.

[0194] Here, since the impact force on the leg housing portion 221 increases towards the end of the leg housing portion 221, the external force transmitted to each part of the power terminal portion 140 and the sensor terminal portion 150 is different.

[0195] Here, the first sensor terminal portion 151 and the cover protrusion portion 112b are separated from each other, and the power terminal portion 140 and the sensor terminal portion 150 rotate, causing the cover body portion 112a adjacent to the cover hole h112 to deform and absorb the impact of external forces.

[0196] If the cover body portion 112a adjacent to the cover hole h112 is not deformed, the power terminal portions 141, 142 and the sensor terminal portions 151, 152 will absorb all the impact, which could lead to damage to the power terminal portions 141, 142 and the sensor terminal portions 151, 152.

[0197] To solve this problem, the present invention presents a structure that can mitigate impact by intentionally separating the first sensor terminal portion 151 and the cover protrusion portion 112b.

[0198] In order to more clearly express the technical concept of the present invention, the attached drawings have been simplified or omitted for configurations that are not related to or have little related to the technical concept of the present invention.

[0199] In the foregoing, the structure and features of the present invention have been described based on embodiments of the present invention. However, the present invention is not limited thereto, and it will be obvious to those skilled in the art that the present invention can be modified or transformed in various ways within the spirit and scope of the invention. Accordingly, it should be made clear that such modifications or transformations fall within the scope of the appended claims. [Explanation of Symbols]
