Fig. 5 is the schematic diagram of the detailed structure of expression flatiron head fuse 3 peripheries, (a) expression partial sectional view, (b) being the III-III cutaway view (in order to simplify accompanying drawing, having omitted the internal structure of ceramic heater 4) of (a), (c) is the p portion of (a) and near the enlarged drawing the q portion.The following detailed structure that flatiron head fuse 3 peripheries are described with reference to Fig. 5.
As mentioned above, be provided with recess 3d in the inside of flatiron head fuse 3, being has the cylindric of the end, and the front of ceramic heater 4 with the tightlock status intercalation wherein.The degree of depth of recess 3d is greater than the length from the front end of ceramic heater 4 to the 4b of heating portion.That is, the temperature detecting part 4a of ceramic heater 4 and the 4b of heating portion are in its state that is covered by flatiron head fuse 3 on every side.The external diameter of the bottom surface side that round-ended cylinder portion is arranged (front) of flatiron head fuse 3 bigger (large-diameter portion 3a).The scope of large-diameter portion 3a is inserted with under the state of ceramic heater 4 in flatiron head fuse 3, is equivalent to the part of temperature detecting part 4a, under the state that flatiron head fuse 3 is intercalated in the protection tube 6, is equivalent to the fore-end of protection tube 6.The round-ended cylinder portion that has with respect to the close base end side of large-diameter portion 3a is the minor diameter part 3b that diameter is slightly less than large-diameter portion 3a.
Be provided with otch 3c in the part (mainly being large-diameter portion 3a and minor diameter part 3b) that forms recess 3d, this otch 3c, will be cut apart perpendicular to the section (section shown in Fig. 5 (b)) in axle center with the plane (being axle center and the plane vertical with paper by recess 3d among Fig. 5 (a)) in the axle center that comprises recess 3d near the bottom surface from the peristome of recess 3d.The depth ratio large-diameter portion 3a that otch 3c enters is darker, and under the state that flatiron head fuse 3 is intercalated in the protection tube 6, the front of otch 3c is exposed and become otch exposed division 3e.
Utilize otch 3c, the large-diameter portion 3a of flatiron head fuse 3 and minor diameter part 3b are easily to the expansion of the both sides of otch 3c.Like this; when with ceramic heater 4 during by plug-in mounting; when its periphery is unrestricted, (be not intercalated in the state in the protection tube 6 as yet); although the inner peripheral surface of the outer peripheral face of ceramic heater 4 and large-diameter portion 3a and minor diameter part 3b connects airtight; but this connect airtight power a little less than, only exist small the air gap (air gap).
Internal diameter when protection tube 6 is in free state is slightly less than large-diameter portion 3a but is slightly larger than minor diameter part 3b.Like this, in case with 3 intercalations of flatiron head fuse in protection tube 6, for being pressed into, and between minor diameter part 3b place and protection tube 6, produced small gap at large-diameter portion 3a place.In near the position the cardinal extremity that is equivalent to flatiron head fuse 3 of protection tube 6 (Fig. 5 (a) and q portion (c)), be provided with the reducing diameter part 6a that is wire along outer peripheral face.On reducing diameter part 6a, the inner surface of the outer peripheral face of minor diameter part 3b and protection tube 6 is butt seamlessly.
Thus, under with the state of flatiron head fuse 3 intercalations in protection tube 6, large-diameter portion 3a and flatiron head fuse 3 peripheries are produced stronger restriction with the part of the reducing diameter part 6a butt of minor diameter part 3b.(the 1st strong cohesiveness point h and the 2nd strong cohesiveness point j's degree of connecting airtight of ceramic heater 4 and flatiron head fuse 3) is enhanced also at the position corresponding with it.Like this, because of connected airtight at the roughly both ends of the part of ceramic heater 4 intercalations in flatiron head fuse 3 powerfully, so whole degree of connecting airtight is improved.
The following describes the effect of the electric iron 10 of said structure.At first, when welding, the operator selects to have the flatiron head side member 20 of the flatiron nose shape of the most suitable operation, is inserted on the main body side member 25.At this moment, unclamp hold-down nut 2 and make O shape circle 12 become free state (release conditions shown in Figure 3), holder 7 is inserted the leading section of housing 1.Because of the base end side of holder 7 is cone-shaped, thus under the state that does not damage O shape circle 12, with less power easily break-through O shape enclose 12.
After holder 7 is inserted into intercalation position shown in Figure 3, again hold-down nut 2 is screwed into make its towards the diagram direction of arrow move.Like this, the interval stenosis of the front end face 1g of housing 1 and the step surface 2g of hold-down nut 2, the O shape that is held circle 12 deforms.Because the outside diameter of O shape circle 12 is subjected to the restriction of extension 1f, internal side diameter is subjected to the restriction of the outer peripheral face 7f of holder 7, and the result is that O shape circle 12 produces distortion with above-mentioned space that is surrounded of landfill.Utilize this distortion, stronger pushing force acts on the outer peripheral face 7f of holder 7 from O shape circle 12, so holder 7 is subjected to powerful the supporting by this frictional force, and is fixed on (hold mode) on the housing 1.Again, the small step 7a that is located at holder 7 is hooked on the O shape circle 12 after the distortion, plays a part to prevent to come off.
After flatiron head side member 20 was inserted main body side member 25, the operator connected the power supply of not shown controller, carried out the temperature of desired flatiron head and set.The electric power slave controller that conforms to design temperature is supplied with to the 4b of heating portion of ceramic heater 4, makes the 4b of heating portion heating.
The heat transferred flatiron head fuse 3 that produces by the 4b of heating portion, but because the large-diameter portion 3a and the minor diameter part 3b of ceramic heater 4 and flatiron head fuse 3 are in good tightlock status, therefore can be fast and low-loss ground carry out this heat and conduct.
The leading section temperature of flatiron head fuse 3 is detected by the temperature detecting part 4a of ceramic heater 4, and signal is passed to not shown controller.Because of being the 1st strong cohesiveness point h near the temperature detecting part 4a, so degree of connecting airtight is high especially, the precision ground that can more increase carries out temperature detection.Like this, even because of welding has temporarily been captured heat from the front end of flatiron head fuse 3, also can carry out quick and correct detection to it by temperature detecting part 4a, thus can be fast and low-loss ground will pass to the front end of flatiron head fuse 3 to its heat that replenishes from the 4b of heating portion.
When using electric iron 10, Yin Gaowen can make the generation thermal deformation slightly by heat of flatiron head fuse 3 and ceramic heater 4.Because of flatiron head fuse 3 different with the material of ceramic heater 4, so coefficient of thermal expansion is also different.When flatiron head fuse 3 and ceramic heater 4, are sustained damage because of its differences in expansion might make ceramic heater 4, but in the structure of present embodiment, can effectively prevent this damage fixedly the time with tightlock status completely.That is, the radial deformation (expansion) of flatiron head fuse 3 can absorb by the width of increase and decrease otch 3c, can prevent that bigger compression stress and tensile force from acting on ceramic heater 4.For axial deformation,,, there are not the bigger compression stress and the effect of tensile force so when connecting airtight, be not easy mutual axial dipole field takes place because of the strong cohesiveness point is controlled in the 1st strong cohesiveness point h and the 2nd this Min. of strong cohesiveness point j again.
When needing transposing flatiron head fuse 3, cut off the electricity supply, unclamp hold-down nut 2 distortion of O shape circle 12 is removed.Under these release conditions, pull out flatiron head side member 20, new flatiron head side member 20 is inserted change.Under release conditions, do not need hold-down nut 2 is taken off from housing 1, make O shape circle 12 be in free state to get final product and only need unclamp hold-down nut 2.Such as, when the axial deflection of the O shape circle 12 that is in hold mode is the pitch of 1mm, negative thread 2b when being 1mm, make its rotation 1 circle can make O shape circle 12 enter release conditions as long as unclamp hold-down nut 2.Like this, can be simply and carry out the transposing of flatiron head side member 20 apace, thus further improve operating efficiency.
In addition, when hold-down nut 2 unclamp more and exceed the institute take, the protruding 5a of plane counter-sunk screw 5 front ends and the cell wall 1d butt of being located at the limiting groove 1e of housing 1 are to stop hold-down nut 2 further towards breaking away from moving of direction (direction opposite with arrow shown in Figure 3).Thus, can prevent the unnecessary operation of taking off or reinstalling reliably because of the wish of running counter to the operator, with hold-down nut 2.In addition, when the occasion of transposing O shape circle 12 etc. need be taken off hold-down nut 2, as long as unclamp plane counter-sunk screw 5 protruding 5a is reduced as far as possible, then hold-down nut 2 can take off easily.
