The first tip portion A-351 and the second tip portion A-361 may have different widths or sizes. The first inclined portion A-352 and the second inclined portion A-362 may have different extension lengths. The first extension A-353 and the second extension A-363 may have different extension lengths. Alternatively, the first positioning protrusion A-35 and the second positioning protrusion A-36 may be positioned so as not to face each other or to not face each other.

[0061] Therefore, when the first positioning protrusion A-35 and the second positioning protrusion A-36 are inserted into the grooves formed in the mold, the second cover A-30 and the first cover A-20 and heater A-10 coupled thereto can be easily positioned in the mold (see FIG. 10). Also, in the process of injecting the molten injection material A-100a into the mold (see FIG. 11), the first round portion A-354 can reduce damage to the part.

[0062] The second plate A-31 does not have to cover the lower side of the inlet hole A-324. The inlet hole A-324 can be open downward. The second plate A-31 can be recessed radially inward from the second outer periphery A-32 in which the inlet hole A-324 is formed, and can be spaced radially inward from the lower part of the inlet hole A-324. The lower part A-321 of the second outer periphery A-32 located between the inlet holes A-324 can be called the recessed part A-321. The recessed part A-321 can be exposed downward as the edge of the second plate A-31 is recessed radially inward.

[0063] Therefore, when the molten extrudate A-100a is injected into the mold, the extrudate can easily flow into the chamber AC through the inlet hole A-324 and the hook hole A-322 (see FIGS. 7 and 11).

[0064] Hereinafter, the structure in which the heater A-10, the first cover A-20 and the second cover A-30 are combined will be referred to as a heater assembly A-HA.

[0065] Referring to Figure 7, the first injection material A-100a can fill the interior of the chamber AC by flowing or being injected into the interior of the covers A-20, A-30 through the inlet holes A-324 and / or hook holes A-322. The first injection material A-100a is in a molten state and can harden inside the chamber AC after being flowed or injected into the interior of the covers A-20, A-30. The first injection material A-100a can fill any gaps that occur at the bonding sites between the covers A-20, A-30 and the heater A-10.

[0066] 8 and 9, the first cover A-20 can be placed on or connected to the second cover A-30. The hook A-222 can be inserted into the hook hole A-322 and hooked onto the second outer periphery A-32. The hook A-222 can prevent the first cover A-20 from being removed upward from the second cover A-30.

[0067] The first plate A-21 can cover the upper side of the second outer periphery A-32. The first plate A-21 can be closely attached to the upper side of the second outer periphery A-32.

The outer periphery of the cover B-32 can press the sealing ring B-20 upward from below toward the stepped portion B-412 of the pipe B-41.

[0166] Therefore, it is possible to prevent droplets from leaking through the gap around the sealing ring B-20.

[0167] Positioning protrusions B-35 and B-36 may protrude upward from the cover bottom B-31. The positioning protrusions B-35 and B-36 may be disposed on the outside of the blocking wall B-33. The positioning protrusions B-35 and B-36 may have a shape corresponding to the positioning grooves B-475 and B-476. The positioning protrusions B-35 and B-36 may be inserted into the positioning grooves B-475 and B-476 to guide the positioning of the cover B-30.

[0168] The first positioning protrusion B-35 and the second positioning protrusion B-36 may have different shapes.

[0170] Therefore, the cover B-30 can be coupled in the forward direction, and the first lead wire B-161 and the second lead wire B-162 can be prevented from being tangled or broken inside or outside the cover B-30.

[0171] 28 and 29, the filler B-100 may be made of the same material as the lower portion B-13 of the heater B-10. The filler B-100 may be integrally formed with the lower portion B-13 of the heater B-10. The thermal expansion coefficient of the filler B-100 may be the same as or approximately the same as the thermal expansion coefficient of the heater B-10.

[0172] Therefore, even if the periphery of the heater B-10 is thermally deformed due to heat generation from the heater B-10, a gap does not need to be formed between the heater B-10 and the filler B-100.

[0173] The width B-w4 of the inner peripheral surface of the blocking wall B-33 may be smaller than the width B-w3 of the inner peripheral surface of the sealing groove B-474. The height of the filler B-100 filled in the sealing groove B-474 may be lower than the height of the sealing wall B-471. The insulating wall B-33 may be disposed below the filler B-100. The insulating wall B-33 may protrude upward from the cover bottom B-31 of the cover B-30. The insulating wall B-33 may be inserted into the opening of the sealing groove B-474. The sealing ring B-20 may be tightly fitted between the step portion B-412 of the pipe B-41, the outer peripheral surface of the recessed portion B-472, and the upper end of the cover outer peripheral portion B-32 to fill the gap.

[0174] Therefore, even if the heater B-10 generates heat and the structure around the heater B-10 is thermally deformed, causing liquid to seep into the sealing groove B-474, the blocking wall B-33 can prevent the liquid from leaking out of the cover B-30 through the wire holes B-361 and B-362 (see Figure 25). Also, the sealing ring B-20 can prevent the liquid from leaking through the gap between the outer periphery B-32 of the cover B-30 and the step portion B-412 of the pipe B-41.
