Disclosure of Invention
Problems to be solved by the invention
In the straight plate clip of patent document 1, when the power of the rechargeable battery is reduced due to long-term use, it is necessary to connect an AC adapter to charge the rechargeable battery. During this charging, the heater cannot be heated because the supply of electric power from the rechargeable battery to the heater is cut off. Therefore, in the case of charging in permanent wave, it is necessary to interrupt permanent wave before the rechargeable battery completes charging.
The invention aims to provide a straight plate clip which can drive a heater by using the power of an external power supply connected in addition to the power of an internal power supply, and can continue to perm without interruption when the power of the internal power supply is reduced.
Means for solving the problems
The present invention is directed to a flat iron, and includes an iron body 1, the iron body 1 including a first arm 2 and a second arm 3 connected to each other so as to be swingable and openable by a swing shaft 4, a first hot plate 7 and a second hot plate 8 provided on the surfaces of the arms 2 and 3 facing each other, and a first heater 9 and a second heater 10 corresponding to the hot plates 7 and 8 arranged inside the arms 2 and 3. First heater 9 and second heater 10 are configured to be driven by electric power supplied from at least one of power supplies 15 and 26, which are provided in iron body 1 and built-in power supply 15 and connected to external power supply 26 of iron body 1 via power supply cable 27. Further, both or one of the first and second heaters 9 and 10 is driven by the electric power of the internal power supply 15 in a state where the external power supply 26 is not connected to the iron body 1, and both or the other of the first and second heaters 9 and 10 is driven by the electric power of the external power supply 26 or the other of the heaters 10 which is not driven by the electric power of the internal power supply 15 in a state where the external power supply 26 is connected to the iron body 1.
The value of the supply current supplied from the external power supply 26 to the second heater 10 can be set to be smaller than the value of the supply current supplied from the internal power supply 15 to the first heater 9.
The built-in power supply 15 is constituted by a rechargeable battery. The heater is provided with a first power supply line 31 for supplying electric power of the built-in power supply 15 to the first heater 9, a second power supply line 34 for supplying electric power of the external power supply 26 to the second heater 10, and a charging line 37 for supplying electric power of the external power supply 26 to the built-in power supply 15. When external power supply 26 is connected to iron body 1 and both heaters 9 and 10 are stopped, the state is switched to the state in which external power supply 26 and internal power supply 15 are connected in series by charging cord 37, and internal power supply 15 is charged with electric power from external power supply 26.
A built-in power supply 15 may be disposed in the first arm 2 provided with the first heater 9, and a power supply socket 28 connected to a power supply switch 17 for switching a power supply state to the first heater 9 and the second heater 10 and a power supply cable 27 may be disposed in the second arm 3 provided with the second heater 10.
The outer shapes of the opposing surfaces of the first hot plate 7 and the second hot plate 8 are formed into substantially the same shape that is long in the longitudinal direction of the clamp arms 2 and 3. First heater 9 may be disposed on the entire surface of first hot plate 7 in the longitudinal direction, and second heater 10 may be disposed facing the plate surface of second hot plate 8 on the open end side of iron body 1.
The second heating plate 8 is composed of at least 2 unit plates 42 and 42 arranged adjacent to each other with a gap in the longitudinal direction of the second heating plate 8. A system in which second heater 10 is disposed on unit plate 42 located on the open end side of iron body 1 can be adopted.
The gaps between the unit plates 42, 42 can be filled with the gasket 43 having excellent heat insulating properties, and the surfaces of the unit plates 42, 42 and the gasket 43 can be formed in the same plane.
The outer shapes of the opposing surfaces of the first hot plate 7 and the second hot plate 8 are formed in rectangular shapes that are long in the longitudinal direction of the clamp arms 2 and 3. The long side length H1 of the first hot plate 7 and the long side length H2 of the second hot plate 8 may be set substantially the same, and the short side length W2 of the second hot plate 8 may be set smaller than the short side length W1 of the first hot plate 7.
Effects of the invention
In the straight blade holder of the present invention, both or one of the first and second heaters 9 and 10 is driven by the electric power of the internal power supply 15 in a state where the external power supply 26 is not connected to the iron body 1, and both or the other of the first and second heaters 9 and 10 is driven by the electric power of the external power supply 26 in a state where the external power supply 26 is connected to the iron body 1, or the other of the heaters 10 is not driven by the electric power of the internal power supply 15. According to the bar clip configured as described above, even when the built-in power supply 15 has sufficient power, the external power supply 26 does not need to be connected, and the hair is permed using the power of the built-in power supply 15. In addition, in a state where the power of the built-in power supply 15 is reduced, the external power supply 26 is connected and the perm is performed using the power of the external power supply 26. As described above, according to the present invention, the first and second heaters 9 and 10 can be driven by the power of the external power supply 26 connected in addition to the power of the built-in power supply 15, and the permanent wave can be continued without interruption even when the power of the built-in power supply 15 is reduced.
If the value of the supply current supplied from the external battery 26 to the second heater 10 is set to be smaller than the value of the supply current supplied from the internal power supply 15 to the first heater 9, a portable battery or the like having an output current value smaller than that of a commercial power supply can be used as the external power supply 26. Accordingly, the second hot plate 8 can be heated even when the output current value of the external power supply 26 is relatively small, and thus, the connectable external power supply 26 can be diversified and the straight plate clip can be highly versatile.
A built-in power supply 15 is disposed inside the first arm 2 provided with the first heater 9, and a power supply socket 28 for connecting a power supply switch 17 for switching the power supply state of both the heaters 9 and 10 and a power supply cable 27 is disposed inside the second arm 3 provided with the second heater 10. As a result, as shown in fig. 1, power switch 17 and built-in power supply 15 are arranged in balance in iron body 1, and the number of lead wires (first and second power supply wires) passing through the portion of swing shaft 4 connecting first arm 2 and second arm 3 is reduced. The built-in power supply 15 and the power switch 17 are arranged as shown in fig. 4, and in this case, the number of lead wires passing through the swing shaft 4 portion increases. As described above, the lead wiring and the internal structure can be easily assembled, and this contributes to improvement in productivity of the straight clip. Further, by avoiding the internal structure of the straight clip from being shifted to either of the clip arms 2 and 3, the weight of the straight clip can be eliminated during permanent wave.
The second heating plate 8 is constituted by at least 2 unit plates 42 and 42 adjacent to each other, and the second heater 10 is disposed on the unit plate 42 located on the open end side of the iron body 1. Accordingly, since only the unit plate 42 on which the second heater 10 is disposed is heated, it is possible to suppress a decrease in the temperature of the second heating plate 8 due to heat conduction to the other unit plate 42, and it is possible to reliably heat a part of the second heating plate 8 to a temperature necessary for permanent waving.
When a gap exists between the unit plates 42 and 42, the hair in the gap cannot be pinched by the two heating plates 7 and 8. However, if the spacers 43 are filled in the gaps between the unit plates 42, 42 and the surfaces of the unit plates 42, 42 and the spacers 43 are formed in the same plane, the hair can be uniformly sandwiched by the entire heating plates 7, 8, and thus the occurrence of hair portions that cannot be permed can be prevented. Further, when the spacer 43 is formed of a material having excellent heat insulating properties, heat conduction to the adjacent unit plates 42 through the spacer 43 can be prevented, and therefore, the unit plates 42 on which the second heater 10 is disposed can be reliably maintained at a temperature necessary for permanent waving.
The long side length H1 of the first hot plate 7 and the long side length H2 of the second hot plate 8, which have rectangular outer contours, are set substantially the same, and the short side length W2 of the second hot plate 8 is set smaller than the short side length W1 of the first hot plate 7. Accordingly, the heat capacity of the second hot plate 8 is reduced, and even when the output current value of the external power supply 26 is relatively small, the entire second hot plate 8 can be heated to the temperature required for permanent wave, and thus permanent wave can be reliably performed.

Detailed Description
(example 1)
Fig. 1 to 3 show an embodiment 1 of the straight plate clip of the present invention. The front-back, left-right, and up-down in the present embodiment are represented by the cross arrows and the front-back, left-right, and up-down marks near the arrows shown in fig. 2. As shown in fig. 2, iron body 1 of the straight clip includes a pair of first clip arm 2 and second clip arm 3 disposed to face each other in the left-right direction, and lower ends of both clip arms 2 and 3 are connected to each other by swing shaft 4 so as to be swingable opened and closed. Each of the arms 2 and 3 has a pair of first and second hot plates 7 and 8 on opposite surfaces thereof at upper ends, and a first heater 9 and a second heater 10 corresponding to the respective hot plates 7 and 8 are disposed inside the respective arms 2 and 3. In the present embodiment, the right arm in fig. 2 is described as the first arm 2, and the left arm may be the first arm 2.
Both clip arms 2 and 3 are urged to open freely by a return spring (not shown) and are held in an open posture shown in fig. 2 in a free state. The grip surfaces 11 of the first hot plate 7 and the grip surfaces 12 of the second hot plate 8 are brought into close contact with each other by gripping the two grip arms 2 and 3 brought into the open position (indicated by two-dot chain lines in fig. 2). In a state where the heater 9 or 10 or any heater 9 or 10 is supplied with a drive current (electric power) to heat the heater plates 7 or 8 or any heater plate 7 or 8, the heated hair is pinched between the pinching surfaces 11 or 12 and slid toward the hair tip, whereby curls and hairs can be straightened straightly. Hair is held between holding surfaces 11 and 12, and the hair is changed into a curly or wavy shape by heating iron body 1 while rotating iron body 1 with the longer (vertical) direction of iron body 1 as the axis of rotation and sliding it toward the hair tips.
The first hot plate 7 and the second hot plate 8 are formed of a rectangular box-shaped aluminum molded product having an open inner surface, and as shown in fig. 3, the clamping surfaces 11 and 12 of the hot plates 7 and 8 are formed in a rectangular shape elongated in the vertical direction (the longitudinal direction of the clamp arms 2 and 3). In the present embodiment, the top-bottom length (long side length) H1 of the first hot plate 7 and the top-bottom length (long side length) H2 of the second hot plate 8 are set to be the same, and the front-back length (short side length) W1 of the first hot plate 7 and the front-back length (short side length) W2 of the second hot plate 8 are set to be the same. Accordingly, the outer shapes of the facing surfaces of the first and second hot plates 7 and 8 are formed to be substantially the same.
Both the first heater 9 and the second heater 10 are configured by PTC heaters, and the second heater 10 is configured by a PTC heater having a lower capacity than the PTC heater configuring the first heater 9. The front and rear lengths of the first and second heaters are set to be the same, the vertical length of the first heater 9 is set to be slightly smaller than the first hot plate 7, and the vertical length of the second heater 10 is set to be substantially half the length of the first heater 9. The first heater 9 is fixed to the plate surface of the inner surface of the first hot plate 7, and is disposed over the entire surface of the first hot plate 7 in the longitudinal direction. Thereby, the first heating plate 7 heats the entire clamping surface 11 thereof substantially uniformly.
A built-in battery (built-in power supply) 15 formed of a lithium ion rechargeable battery is disposed inside the first arm 2, and the built-in battery 15 includes a battery control circuit 16 that controls charging and discharging of the built-in battery 15. A two-stage switching type (off, on) power switch 17 for switching the power supply state of the heaters 9 and 10 is disposed in the second arm 3, and the power switch 17 is operated by a slide knob 18 disposed on the left side surface of the second arm 3 and slidable up and down. The power switch 17 includes three-circuit simultaneous switching switches composed of first to third switches 21 to 23. When the slide knob 18 is operated and the power switch 17 is located at the off position, the first switch 21 and the second switch 22 are in the on state and the third switch 23 is in the off state, and when the power switch 17 is located at the on position, the first switch 21 and the second switch 22 are in the off state and the third switch 23 is in the on state (see fig. 1).
The connection terminal on the external power supply 26 side of power supply cable 27 is constituted by a USB (universal Serial bus) connector (male terminal) of the USB specification, and the connection terminal on the iron main body 1 side is constituted by a coaxial connector (male terminal) having a positive electrode and a negative electrode coaxially. A power supply socket 28 (female terminal) corresponding to the coaxial connector of the power supply cable 27 is provided at the lower end of the first clip arm 2. As shown in fig. 2, by connecting a USB connector to an output terminal (female terminal) of external power supply 26 and connecting a coaxial connector to power supply socket 28, electric power of external power supply 26 can be supplied to iron body 1 through power supply cable 27. The external power supply 26 in fig. 2 represents a mobile battery. Although not shown, the power supply socket 28 incorporates a protection circuit for controlling the value of the input current, and the protection circuit converts the value of the supply current of the power input from the external power supply 26 to 1A, for example.
As described above, by using a USB connector for the connection terminal on the external power supply 26 side, a mobile battery, a power adapter connectable to a USB terminal provided in a personal computer or a commercial power supply provided with a USB output terminal, or the like can be used as the external power supply 26. Further, the connection terminal on the side of iron body 1 may be a connector having an existing connector specification or a dedicated connector having a positive electrode and a negative electrode, in addition to the coaxial connector. When the specification of the connector of the connection terminal is changed, power supply socket 28 corresponding to the specification of the connector of the connection terminal is mounted on iron body 1.
First power feeding line 31, which is a lead wire for supplying electric power of internal battery 15 to first heater 9, is provided inside iron body 1. Specifically, the first power supply line 31 includes a first positive line 32 connecting the positive electrode of the built-in battery 15 and one terminal of the first heater 9, and a first negative line 33 connecting the negative electrode of the built-in battery 15 and the other terminal of the first heater 9. The first switch 21 is connected to the middle portion of the first negative line 33, and the power supply state of the first heater 9 is switched by opening and closing the first switch 21.
Further, second power feeding line 34 formed of a lead wire for supplying electric power from external power supply 26 to second heater 10 is provided inside iron body 1. Specifically, the second power supply line 34 includes a second positive line 35 connecting the positive electrode of the power supply socket 28 and one terminal of the second heater 10, and a second negative line 36 connecting the negative electrode of the power supply socket 28 and the other terminal of the second heater 10. The second switch 22 is connected to the middle portion of the second negative line 36, and the power supply state of the second heater 10 is switched by opening and closing the second switch 22 in a state where the external power supply 26 is connected.
Charging cord 37, which is constituted by a lead wire connecting external power supply 26 and internal power supply 15 in series, is provided to charge internal battery 15 with electric power from external power supply 26 in a state where external power supply 26 is connected to iron body 1 and both heaters 9 and 10 are stopped. Specifically, the charging line 37 includes a positive charging line 38 connecting the first positive line 32 and the second positive line 35, a negative charging line 39 connecting the first negative line 33 between the internal battery 15 and the first switch 21 and the second negative line 36 between the external power supply 26 and the third switch 23, and the first positive line 32 and the second positive line 35. The third switch 23 before connection is connected to the middle of the negative charging wire 39, and the power supply to the internal battery 15 is controlled by opening and closing the third switch 23.
The second feeder cable 34 and the charging cable 37 convert (as in 1A) the value of the supply current of the electric power inputted through the protection circuit built in the feeder cable 28 and are limited. However, in the case of the internal battery 15 configured by a lithium ion rechargeable battery, since the supply current value is at most 4A, the first power supply line 31 uses a lead wire having a higher allowable current (a larger cross-sectional area of the lead wire) than the second power supply line 34 and the charging line 37.
As described above, the built-in battery 15 is disposed inside the first arm 2 provided with the first heater 9 driven by the electric power of the built-in battery 15, and the power supply socket 28 connected to the power switch 17 and the power supply cable 27 for switching the power supply state of the both heaters 9 and 10 is disposed inside the second arm 3 provided with the second heater 10 driven by the electric power of the external electric power 26. As a result, as shown in fig. 1, power switch 17 and internal power supply 15 are arranged in balance in iron body 1, and the number of lead wires of first power supply line 31 and second power supply line 34 passing through swing shaft 4 connecting first arm 2 and second arm 3 can be set to 3. The internal power supply 15 and the power switch 17 are arranged as shown in fig. 4 described later, for example, but in this case, the number of lead wires passing through the swing shaft 4 is 4. As described above, since the number of leads passing through the swing shaft 4 can be reduced, the wiring of the leads and the assembly of the internal structure can be facilitated, which contributes to the improvement of the productivity of the straight clip. In addition, by avoiding the internal structure of the straight clip from deviating to either one of the clip arms 2, 3, the excess weight of the straight clip during permanent wave can be eliminated.
When the slide handle 18 is slid upward and the power switch 17 is switched to the on position in a state where the external power supply 26 is not connected and sufficient power is available in the built-in battery 15, the first and second switches 21 and 22 are in the off state and the third switch 23 is in the on state, and the power of the built-in battery 15 is supplied to the first heater 9 through the first power supply line 31 to heat the first hot plate 7. When the use of the internal battery 15 is continued and the power of the internal battery 15 is reduced, the driving current is not supplied to the first heater 9, and the heating of the first heating plate 7 is stopped. In this state, the output terminal of the external power supply 26 and the power supply socket 28 are connected by the power supply cable 27, and the second heater plate 8 is heated by supplying the electric power of the external power supply 26 to the second heater 10 through the second power supply line 34. When external power supply 26 is connected to iron body 1 in a state where sufficient electric power is available in built-in battery 15, both first and second hot plates 7 and 8 are heated. As described above, according to the bar clip of the present embodiment, even when the user goes out, the permanent wave can be easily performed by the power of the built-in battery 15. When permanent waves are to be formally permed in a state where both heating plates 7 and 8 are heated, a commercial power supply or the like at home may be used as the external power supply 26. When the portable power source is carried while going out, both heating plates 7 and 8 can be heated and permanent waving can be performed even while going out.
When the power switch 17 is switched to the off position in a state where the external power supply 26 is connected, the first and second switches 21 and 22 are turned on, and the supply of the driving current to the heaters 9 and 10 is stopped. At this time, since the third switch 23 is in the off state, the external power supply 26 and the internal battery 15 are connected in series by the charging wire 37, and the power of the external power supply 26 is supplied to the internal battery 15. The built-in battery 15 is charged by the supply of the electric power. The charging operation of the internal battery 15 is controlled by the battery control circuit 16, and when the internal battery 15 is fully charged, the battery control circuit 16 stops the charging operation of the internal battery 15.
(example 2)
Fig. 4 shows example 2 in which the arrangement of the built-in battery 15 and the power switch 17 is changed. Therefore, a power switch 17 is disposed inside the first arm 2 in which the first heater 9 is disposed, and a built-in battery 15 is disposed inside the second arm 3 in which the second heater 10 is disposed. As in the present embodiment, when power switch 17 is disposed in first arm 2 and built-in battery 15 and power supply socket 28 are disposed in second arm 3, first power supply line 31 and second power supply line 34 need to be wired to power switch 17, and accordingly, the number of lead wires passing through the swing shaft 4 portion is increased to 4, which makes it impossible to avoid a situation where the internal structure of iron body 1 is slightly complicated. Since the rest is the same as that of embodiment 1, the same components are denoted by the same reference numerals and the description thereof is omitted. The same applies to the following description.
(example 3)
Fig. 5 shows example 3 in which the arrangement of the internal battery 15 and the power switch 17 is changed again. Therefore, the built-in battery 15 and the power switch 17 are disposed inside the second arm 3. As in the present embodiment, if the built-in battery 15, the power switch 17, and the power supply socket 28 are arranged in a group, only the first power supply line 31 may be arranged from the second arm 3 to the first arm 2, and therefore, this is advantageous in that the number of lead wires passing through the portion of the swing shaft 4 can be minimized. However, the internal structure is disposed so as to be concentrated inside the second clamp arm 3, and complication of the internal structure cannot be avoided. In addition, the balance of iron body 1 is lost, and the straight clip may be heavy during permanent wave.
In the above-described straight blade holder of each embodiment, only the first heater 9 is driven by the power of the built-in battery 15, and only the second heater 10 is driven by the power of the external power supply 26 in a state where the external power supply 26 is connected to the iron main body 1. According to such a bar clamp, since the built-in battery 15 supplies power only to the first heater 9, consumption of the built-in battery 15 can be suppressed as compared with the case where power is supplied to both heaters 9 and 10. Even in a state where the power of the internal battery 15 is reduced, the external power supply 26 is connected to supply power to the second heater 10, thereby heating the second hot plate 8. As described above, according to the above-described embodiments, permanent wave can be performed for a long time by the built-in battery 15, and permanent wave can be continued by connecting the external power supply 26 even when the power of the built-in battery 15 is reduced. Further, since a simple circuit configuration in which the built-in battery 15 and the first heater 9, and the external power supply 26 and the second heater 10 are connected in a one-to-one manner can be adopted, there is also an advantage that the internal configuration of the straight plate clip can be simplified. Further, when the external power supply 26 is connected in a state where the built-in battery 15 has sufficient power, both the first heater 9 and the second heater 10 can be heated, so that the hair sandwiched between the two heating plates 7 and 8 can be heated at an appropriate temperature as soon as possible, and the time required for permanent wave can be shortened.
If the value of the supply current supplied from the external power supply 26 to the second heater 10 is set to be smaller than the value of the supply current supplied from the built-in battery 15 to the first heater 9, a portable power source or the like having an output current value smaller than that of a commercial power source can be used as the external power supply 26. Accordingly, the second hot plate 8 can be heated even when the output current value of the external power supply 26 is relatively small, and thus, the connectable external power supply 26 can be diversified and the straight plate clip can be highly versatile.
In a state where external power supply 26 is connected to iron body 1 and both heaters 9 and 10 stop operating, the external power supply 26 and internal battery 15 are connected in series, and internal battery 15 is charged with electric power from external power supply 26. Thus, the built-in battery 15 can be charged and ready for the next use only by connecting the external power supply 26 in advance when the bar clamp is not in use. Further, it is not necessary to provide a charging socket or the like for incorporating the battery 15, and accordingly, the structure of the straight plate clip can be further simplified, and the design of the straight plate clip can be further improved.
(example 4)
Fig. 6 shows embodiment 4 in which the shape of the second heating plate 8 is changed. Accordingly, the short side length W2 of the second heating plate 8 is set smaller than the short side length W1 of the first heating plate 7. Accordingly, even when the output current value of the external power supply 26 is relatively small or the second heater 10 is formed of a low-capacity PTC heater, the heat capacity of the second heating plate 8 is reduced, and the entire second heating plate 8 can be heated to a temperature required for permanent wave treatment, so that permanent wave treatment can be performed reliably.
(example 5)
Fig. 7 shows embodiment 5 in which the structure of the second heating plate 8 is changed. Therefore, the second heating plate 8 is composed of 2 unit plates 42 and 42 of the same shape which are adjacently arranged with a gap in the longitudinal direction. Second heater 10 is disposed on unit plate 42 located on the upper end side (open end side) of iron body 1. The gap between the unit plates 42 and 42 is filled with a spacer 43, and the surfaces of the unit plates 42 and the spacer 43 are formed in the same plane. The spacer 43 is preferably made of a material having excellent heat insulating properties and not deformed when the hair is held between the holding surfaces 11 and 12, and examples thereof include a hard plastic material and a hard foamed plastic material.
According to the second heating plate 8 as described above, since only the unit plate 42 on which the second heater 10 is disposed is heated, it is possible to suppress a decrease in the temperature of the second heating plate 8 due to conduction of heat to the other unit plate 42, and it is possible to reliably heat a part of the second heating plate 8 to a temperature necessary for permanent wave. Since each unit plate 42 has a small heat capacity, even when the output current value of the external power supply 26 is relatively small or the second heater 10 is configured by a low-capacity PTC heater, the entire unit plate 42 in which the second heater 10 is disposed can be heated to a temperature necessary for permanent wave.
In the case where the unit plates 42 and 42 have a gap therebetween, when hair is held between the heating plates 7 and 8, the hair cannot be held in the gap. However, if the spacers 43 are filled in the gaps between the unit plates 42, 42 and the surfaces of the unit plates 42, 42 and the spacers 43 are formed in the same plane, the hair can be uniformly held by the entire heating plates 7, 8, and thus the occurrence of hair portions that cannot be permed can be prevented. Further, if the spacer 43 is formed of a material having excellent heat insulating properties, heat conduction to the adjacent unit plates 42 through the spacer 43 can be prevented, and therefore, the unit plates 42 in which the second heater 10 is disposed can be reliably maintained at a temperature necessary for permanent waving.
In example 5, the second heating plate 8 is constituted by 2 unit plates 42, but the second heating plate 8 can be constituted by 3 or more than 3 unit plates 42. In this case, the spacers 43 are filled in the respective gaps. In the case where the second heating plate 8 is configured by more unit plates 42, the second heaters 10 may be respectively disposed at a plurality of unit plates 42 located at the front end side of the second clamp arm 3. The upper and lower lengths of the unit plates 42 may be different.
(example 6)
Fig. 8 shows example 6 in which the driving modes of the first and second heaters 9 and 10 are changed. Therefore, both first and second heaters 9 and 10 are driven by the electric power of internal battery 15 in a state where external power supply 26 is not connected to iron body 1, and both first and second heaters 9 and 10 are driven by the electric power of external power supply 26 in a state where external power supply 26 is connected to iron body 1. The first arm 2 is provided with 2 built-in batteries 15 connected in series, and the second arm 3 is provided with a power switch 17 and a power supply socket 28. The first and second heaters 9 and 10 are configured by PTC heaters having the same capacity.
The power switch 17 of the present embodiment is of a three-stage switching type (off, on 1, on 2), and includes a two-circuit simultaneous switching switch composed of an upstream side switch 50 and a downstream side switch 51. When the slide knob 18 is operated and the power switch 17 is located at the off position, the upstream side switch 50 is in the off state and the downstream side switch 51 is in the on state, and when the power switch 17 is located at the on 1 position, both the switches 50 and 51 are in the off state, and when the power switch 17 is located at the on 2 position, the upstream side switch 50 is in the on state and the downstream side switch 51 is in the off state (see fig. 8).
The first and second heaters 9 and 10 are connected in parallel by a first parallel line 52 connecting one ends of the heaters 9 and 10 and a second parallel line 53 connecting the other ends of the heaters 9 and 10. The first parallel line 52 is connected to the positive electrode of the internal battery 15 by an internal positive electrode line 54, and the second parallel line 53 is connected to the negative electrode of the internal battery 15 by an internal negative electrode line 55. The power switch 17 is connected in series to a middle portion of the built-in positive line 54. The positive external positive line 56 of the power supply socket 28 is connected to the internal positive line 54 between the upstream switch 50 and the downstream switch 51, and the negative external negative line 57 of the power supply socket 28 is connected to the internal negative line 55.
When the slide handle 18 is slid upward and the power switch 17 is switched to the on 1 position in a state where the external power supply 26 is not connected, both the switches 50 and 51 are in the off state, and the electric power of the internal battery 15 is supplied to both the heaters 9 and 10 through the internal positive electrode line 54, the internal negative electrode line 55 and both the parallel lines 52 and 53, thereby heating the first and second hot plates 7 and 8. In a state where the output terminal of the external power supply 26 and the power supply socket 28 are connected by the power supply cable 27, when the slide knob 18 is slid upward and the power switch 17 is switched to the on 2 position, the upstream side switch 50 is turned on, the downstream side switch 51 is turned off, and the external power supply 26 is supplied to the heaters 9 and 10 via the external positive electrode line 56 and the external negative electrode line 57, the parallel lines 52 and 53, the internal positive electrode line 54, and the internal negative electrode line 55, thereby heating the first and second hot plates 7 and 8.
When the power switch 17 is in the off position and the external power supply 26 is connected, the external power supply 26 is supplied to the internal battery 15 through the external positive line 56 and the internal positive line 54 and the external negative line 57 and the internal negative line 55, and the internal battery 15 is charged by the supply of the electric power. In the present embodiment, when power switch 17 is switched to on 1 position in a state where sufficient power is available in built-in battery 15 and external power supply 26 is connected to iron body 1, drive current is supplied from built-in battery 15 and external power supply 26 to first and second heaters 9 and 10. Therefore, each of the wires 52 to 57 is formed of a lead wire having a large allowable current.
In example 6, the first and second heaters 9 and 10 are configured by PTC heaters having the same capacity, but the first and second heaters 9 and 10 may be configured by PTC heaters having different capacities. The first and second heaters 9 and 10 are connected in parallel, and the wires 52 to 57 are formed of lead wires having a large allowable current, so that the external power supply 26 having a relatively large supply current value can be connected.
As described above, in the straight blade holder according to each of the above embodiments, both or one of the first and second heaters 9 and 10 is driven by the power of the built-in battery 15 in a state where the external power supply 26 is not connected to the iron body 1, and both or the other heater 10 is driven by the power of the external power supply 26 in a state where the external power supply 26 is connected to the iron body 1. According to the bar clip configured as described above, in a state where the internal battery 15 has sufficient power, the external power supply 26 does not need to be connected, and the perm can be performed using the power of the internal battery 15, and the perm can be performed using the power of both the internal battery 15 and the external power supply 26 by connecting the external power supply 26. In addition, in a state where the power of the built-in battery 15 is reduced, the external power supply 26 can be connected and the perm can be performed using the power of the external power supply 26. As described above, according to the above embodiments, the first and second heaters 9 and 10 can be driven by the power of the connected external power supply 26 in addition to the power of the built-in battery 15, and the permanent wave can be continued without interruption even when the power of the built-in battery 15 is reduced.
Since the built-in power supply 15 built in the iron body 1 for the straight iron of each of the above embodiments drives both the first and second heaters 9 and 10 or one of the heaters 9, the straight iron is excellent in portability and can be suitably applied to permanent wave at an outgoing place or the like. In addition to the above-described embodiments, the built-in battery 15 may be a disposable battery, in which case the built-in battery 15 is replaceably built in the first clip arm 2. The first and second heaters 9 and 10 may be constituted by ceramic heaters, closed heaters, peltier elements, or the like, in addition to the PTC heaters. The power supply line connecting the internal structures of the built-in power supply 15, the power switch 17, the power supply socket 28, and the like is not limited to the embodiment described in the embodiment. The external power supply 26 may be an AC adapter or the like that is inserted into a USB terminal provided in a personal computer or a commercial power supply and can output dc power. The power supply cable 27 can be a USB cable having both ends constituted by connectors of USB specification. Such a power supply cable 27 is easy to be introduced at low cost because of most distribution. Further, for example, a USB cable connecting a personal computer and a digital camera can be used as power supply cable 26 for supplying electric power from external power supply 26 to iron body 1.
