200305363 玫、發明說明 【發明所屬之技術領域】 本發明係關於以驅除害蟲及防菌防黴用之用於煙燻劑 充塡容器的發熱體保持板及其製造方法，暨具有該發熱體 保持板爲特徵的煙燻劑充塡容器。 【先前技術】 作爲在室內等密閉空間內驅除害蟲和進行防菌防黴處 理的手段，煙燻劑被廣泛地使用，而充塡這樣的煙燻劑的 煙燻劑充塡容器也已經實用化。 上述煙燻劑充塡容器一般如圖6和圖7所示，由容納煙 燻劑104的收容部分103和上蓋102組成的金屬容器構成。 在上蓋102上設有用於露出點火用發熱體105的點火頭 106的中央孔107和多個噴煙孔（未圖示），而在該上蓋1〇2 上安裝著裝有點火用發熱體105的發熱體保持板108。 並且，在發熱體保持板108上，形成有裝有點火用發熱 體105的安裝孔109和多個噴煙孔（未圖示），此安裝孔1〇9 周邊部向上立起，以便能夠保持點火用發熱體1 05。 如上所述的煙燻劑充塡容器通常是在嵌有紙管等耐熱 性外筒的狀態下，例如收容在合成樹脂製造的外裝容器內 的狀態下使用。 【發明內容】 (發明所欲解決之問題） 如圖6和圖7所示的煙燻劑充塡容器，通過用摩擦板摩 擦點火用發熱體1 0 5的點火頭1 〇 6來點火，由此使點火用 發熱體內部的發熱劑燃燒，由產生的熱量使煙燻劑1 〇 4發 7 312/發明說明書(補件)/92-06/92107727 200305363 煙，通過發熱體保持板108和上蓋102的噴煙孔將煙釋放 到外部。 但是，安裝著現有點火用發熱體1 05的發熱體保持板 108，使用的是整個面上有多個穿孔（有孔金屬板），或未加 工的金屬板的圓盤狀物體，在前一種情況下，在其中心部 位形成的安裝孔的周圍，形成任意形狀的孔（上述多個孔爲 與安裝孔形成一體的任意形狀的孔），在後一種情況下，安 裝孔是單純的圓形。 因此，在安裝孔1 09的周邊部向上立起的情況下，在前 者的例子中，爲了防止安裝點火用發熱體1 05時，插入強 度增大、發熱體保持板1 08變形，有必要加厚板的厚度， 這對降低材料成本是不利的。在後者的例子中，由於安裝 孔周邊部的向上立起部幾乎不可能有彈性地擴大孔徑，與 安裝點火用發熱體105時需要很大的力相反，在用摩擦板 摩擦點火用發熱體1 05的點火頭1 06進行點火時，具有點 火用發熱體105易於從安裝孔109中脫落的問題。 本發明之目的在於，提供一種以解決上述先前技術所具 有的問題，通過使板材的厚度變薄而實現材料成本降低， 同時，以具有能提高所安裝的點火用發熱體的保持力的新 型結構的發熱體保持板，以及能夠高效地製造這樣的發熱 體保持板的製造方法，和具有該發熱體保持板爲特徵的煙 燻劑充塡容器。 (解決問題之手段） 爲了實現如上目的而完成的本發明之構成，如下所述。 即，本發明的發熱體保持板具有如下的特徵，在固定於 8 312/發明說明書(補件)/92-06/92107727 200305363 充塡了煙燻劑的容器內的發熱體保持板上具有安裝煙燻劑 點火用發熱體的安裝孔和多個噴煙孔， 在上述安裝孔的周邊部，形成有由多個分割溝大致等間 隔地分離的多個可彈性地擴大孔徑的彎曲支持片。 按照上述本發明的發熱體保持板，由多個分割溝大致等 間隔地分離的多個可彈性地擴大孔徑的彎曲支持片形成於 安裝孔的周邊部。而且多個支援片的數目較佳是2〜20 個，更佳是3〜9個。 由於可彈性地擴大孔徑的支援片可以吸收安裝點火用 發熱體時的力，所以使用196N(20kgf)以下，平均98N(10kgf) 左右的力可以容易地將點火用發熱體安裝在發熱體保持板 的安裝孔上。 另外，由於要使點火用發熱體脫落，根據支援體的彈 力，需要98N(10kgf)以上的載荷，能夠保持很高的保持力， 所以在用摩擦板摩擦點火用發熱體的點火頭進行點火時， 就能夠防止點火用發熱體由安裝孔中脫落。另外能夠根據 點火用發熱體的形狀適當設計上述支持片彎曲的方向和角 度。 保持在本發明的發熱體保持板上的點火用發熱體，在安 裝到發熱體保持板的安裝部的周邊部具有多個突起部，該 突起部較佳爲數量多於上述多個分割溝。按照如此的結 構，在將點火用發熱體安裝到發熱體保持板的安裝孔中 時，即使點火用發熱體的上述突起部和發熱體保持板的分 割溝互相並非完全一致地對應，也能夠有效地提高點火用 發熱體的保持力。 9 312/發明說明書(補件)/92-06/92107727 200305363 上述多個噴煙孔以上述安裝孔爲中心而形成，而且，在 這些噴煙孔的周圍，較佳形成有突起狀的剛性補強部。按 照這樣的結構，由於上述突起部能夠有效地補強因形成多 個噴煙孔而降低了的發熱體保持板的平面剛性，所以能夠 使發熱體保持板的厚度變薄，從而降低製造成本。另外， 形成於上述噴煙孔周圍的突起狀剛性補強部，只要能夠有 效地補強發熱體保持板，對其形態就沒有特別的限制，例 如可在多個噴煙孔之間形成多個突起部；在噴煙孔的周 圍’在同心圓上形成一個以上的環狀突起部；在噴煙孔的 周圍形成一連串的突起部。 本發明包括以具有上述本發明發熱體保持板爲特徵的 煙燻劑充塡容器。 另外，本發明的發熱體保持板之製造方法是用於製造具 有安裝煙燻劑點火用發熱體的安裝孔、以該安裝孔爲中心 形成的多個噴煙孔和形成於該噴煙孔周圍的突起狀剛性補 強部的、被固定在充塡有煙燻劑的容器內的發熱體保持板 的方法， 其特徵在於，具有： 在由卷材製成的基板上，在周邊部以大致相等的間隔形 成具有多個分割溝的上述安裝孔，同時形成一部分上述多 個噴煙孔的第一步驟； 使由發熱體保持板的外形部以及上述分割溝分離的安 裝孔的周邊部彎曲，同時形成上述剛性補強部的第二步驟； 形成其餘的上述多個噴煙孔的第三步驟； 由上述基板抽出位於上述外形部發熱體保持板的第四 10 312/發明說明書(補件)/92-06/92107727 200305363 步驟。 並且，本發明中的卷材，是指由無錫薄鋼板、鍍鋅鋼板、 不銹鋼板、鋁板、鍍錫鋼板等金屬成型爲卷狀的金屬板。 並且，本發明的另一種發熱體保持板之製造方法是用於 製造具有安裝煙燻劑點火用發熱體的安裝孔、以該安裝孔 爲中心形成的多個噴煙孔和形成於該噴煙孔周圍的突起狀 剛性補強部的、被固定在充塡有煙燻劑的容器內的發熱體 保持板的方法， 其特徵在於，具有： 在由卷材製成的基板上，在周邊部以大致相等的間隔形 成具有多個分割溝的上述安裝孔，同時形成一部分上述多 個噴煙孔的第一步驟； 使發熱體保持板的外形部彎曲，同時形成上述剛性補強 部的第二步驟； 在彎曲由上述分割溝分離的安裝孔的周邊部的同時，形 成其餘上述多個噴煙孔的第三步驟；以及 從上述基板抽出位於上述外形部的發熱體保持板的第 四步驟。 按照上述本發明的製造方法，特別通過分別在第一步驟 和第三步驟中形成多個噴煙孔，可使各步驟中所用的模具 進一步簡化，能夠提高其耐久性。並且，由於在由第一步 驟形成安裝孔和一部分噴煙孔的基板上，由第二步驟形成 剛性補強部，提高了基板的平面剛性，因而就可防止在第 三步驟中形成其餘噴煙孔時基板的變形，能夠連續而高效 地製造符合設計的製品。 11 312/發明說明書(補件)/92-06/92107727 200305363 【實施方式】 下面說明本發明的實施形態例，但本發明不限於這些例 子。 首先，參照圖1和圖2說明本發明的發熱體保持板。 圖1爲顯示裝有本發明的發熱體保持板的煙燻劑充塡容 器一個例子的局部切口剖面圖。圖2爲顯示此發熱體保持 板的75意圖，（a)爲俯視圖，（b)爲沿著（a)中的A - A，線所作 的部分剖面圖，（c)爲（b)中B的局部放大圖。 如圖1和圖2所示，本實施例的煙燻劑充塡容器1主要 是由容納煙燻劑4的收容部3和上蓋2組成的金屬容器構 成。 在上蓋2的上面，設有露出點火用發熱體5的點火頭6 的中央孔7以及多個噴煙孔（未圖示），而在上蓋2的內側， 安裝著裝有點火用發熱體5的發熱體保持板8。 在發熱體保持板8的中央，形成有安裝點火用發熱體5 用安裝孔9，在該安裝孔9的周邊部，等間隔地形成多個（在 本實施例中是5個）呈半圓形的分割溝1 0。因此，由這些 分割溝1 0分離的安裝孔9的周邊部，在上方彎曲成一定的 角度（在本實施例中是大約77° )地形成多個支持片11。 並且，這些支持片所彎曲的角度，較佳不到90 °，更佳 在50 °以上但不到90 °。 如上所述呈錐狀彎曲的多個支持片11，由於在由安裝孔 9的下方安裝點火用發熱體5時可彈性地擴大孔徑，因此 使用較小的力就能夠安裝點火用發熱體5，同時，能夠在 安裝後利用其彈力有效地支持點火用發熱體5。關於這一 12 312/發明說明書(補件)/92-06/92107727 200305363 點，用幾個試驗結果進行更加詳細的說明。 表1表示在本實施例的發熱體保持板8和現有的發熱體 保持板（使用有孔金屬板和未加工金屬板）上安裝點火用發 熱體5時的插入強度和發熱體保持板有無變形、以及安裝 的點火用發熱體的脫落強度和點火時有無脫落的試驗結 果。並且，表1中的插入強度和脫落強度的測定方法如下。 (插入強度的測定） 將點火用發熱體插入發熱體保持板的安裝孔，由 S t r 〇 g r a p h (試驗速度1 0 0 m m / m i η)測定的安裝在適當位置時 所需的最大載荷。 (脫落強度的測定） 由Strograph(試驗速度100mm/min)測定的使安裝在發熱 體保持板上的點火用發熱體由安裝孔脫落（包括沒有脫落 時使發熱體保持板變形的情況）所需的最大載荷。 13 312/發明說明書(補件)/92-06/92107727 200305363 丨點火時 j脫落 戡 戡 摧 躲 摧 脫落強度_ CO 00 〇〇 <N CO CSI 〇〇 寸 <x> C-j CO (N CD CO CD CN 2 00 1 rH ΙΟ Ο io ο 〇 插入時 變形 m 联 m 媒 m 躲 插入強度(kgf) CO 〇0 o s 〇〇 1 卜 ΪΟ 00 00 <N 〇 1 oq c〇 ίΩ 卜 卜 寸 板厚 (mm) 0.21 0.23 0.32 寸 d 寸 d 0.24 0.28 安裝孔的特徵 f錄 墨画^ 气,α·酲G嫛 鹗.S你 5 ^ 11 1^1?

[Prior art] As a means of exterminating pests and carrying out antibacterial and mildew treatment in closed spaces such as indoors, fumigants are widely used, and fumigant filling containers filled with such fumigants have also been put into practical use. . As shown in Figs. 6 and 7, the above-mentioned smoking agent filling container is generally composed of a metal container composed of an accommodating portion 103 and an upper cover 102 for containing the smoking agent 104. The upper cover 102 is provided with a central hole 107 of the ignition head 106 and a plurality of smoke spray holes (not shown) for exposing the heating element 105 for ignition, and the upper cover 102 is provided with heat generated by the heating element 105 for ignition.体 保护 板 108。 Body holding plate 108. In addition, the heating body holding plate 108 is formed with a mounting hole 109 in which the heating element 105 for ignition and a plurality of smoke spray holes (not shown) are formed, and the peripheral portion of this mounting hole 10 is raised upward so that the ignition can be maintained 05 with a heating element. Such a fumigant-filled container is usually used in a state in which a heat-resistant outer tube such as a paper tube is embedded, for example, in a state of being housed in an external container made of synthetic resin. [Summary of the Invention] (Problems to be Solved by the Invention) The fumigant-filled container shown in FIG. 6 and FIG. 7 is ignited by rubbing the ignition head 10 of the heating element 105 for ignition with a friction plate to ignite, This causes the heat generating agent inside the ignition heating element to burn, and the generated heat causes the fumigant 104 to emit 7 312 / Instruction Manual (Supplement) / 92-06 / 92107727 200305363, and the heat is held by the heating element holding plate 108 and the upper cover. The smoke vent of 102 releases smoke to the outside. However, the heating element holding plate 108 on which the existing heating element 105 for ignition is installed is a disc-shaped object having a plurality of perforations (hole-shaped metal plates) on the entire surface or an unprocessed metal plate. In the case, a hole of an arbitrary shape is formed around the mounting hole formed at the center thereof (the above-mentioned plurality of holes are holes of any shape integrated with the mounting hole). In the latter case, the mounting hole is a simple circle . Therefore, in the case where the peripheral portion of the mounting hole 109 stands up, in the former example, in order to prevent the insertion strength from increasing when the heating element 105 for ignition is installed, the heating element holding plate 108 needs to be added. The thickness of thick plates is not good for reducing material costs. In the latter example, since the upwardly rising portion of the peripheral portion of the mounting hole can hardly expand the aperture elastically, as opposed to requiring a large force when mounting the ignition heating element 105, the ignition heating element 1 is rubbed with a friction plate. When the ignition head 05 of 06 is ignited, there is a problem that the heating element 105 for ignition is easily detached from the mounting hole 109. An object of the present invention is to provide a new structure that can solve the problems of the above-mentioned prior art, reduce the material cost by reducing the thickness of the plate material, and improve the holding force of the mounted heating element for ignition. A heating element holding plate, a manufacturing method capable of efficiently producing such a heating element holding plate, and a fumigant-filled container having the heating element holding plate. (Means for Solving the Problems) The structure of the present invention accomplished in order to achieve the above-mentioned object is as follows. That is, the heating element holding plate of the present invention has the following features. The heating element holding plate is fixed to the heating element holding plate fixed in 8 312 / Invention Specification (Supplement) / 92-06 / 92107727 200305363 in a container filled with a fumigant. The mounting hole and the plurality of smoke spray holes of the heat generating body for the ignition of the fumigant are formed at the peripheral portion of the mounting hole with a plurality of curved support pieces that can be elastically enlarged in diameter and separated by a plurality of divided grooves at substantially equal intervals. According to the heating element holding plate of the present invention described above, a plurality of curved support pieces capable of elastically expanding the apertures are formed at a peripheral portion of the mounting hole by a plurality of divided grooves separated at substantially equal intervals. In addition, the number of the plurality of supporting pieces is preferably 2 to 20, and more preferably 3 to 9. The support sheet that can elastically enlarge the aperture can absorb the force when mounting the heating element for ignition. Therefore, the heating element for ignition can be easily installed on the heating element holding plate with a force of 196N (20kgf) or less and an average of about 98N (10kgf). Mounting holes. In addition, because the heating element for ignition is to be disengaged, a load of 98N (10kgf) or more is required according to the elastic force of the support body, and a high holding force can be maintained. This can prevent the heating element for ignition from falling out of the mounting hole.

First, a heating body holding plate of the present invention will be described with reference to FIGS. 1 and 2. Fig. 1 is a partially cutaway sectional view showing an example of a fumigant filling container equipped with a heating body holding plate of the present invention. Fig. 2 is a schematic view showing 75 of the heating body holding plate, (a) is a plan view, (b) is a partial cross-sectional view taken along line A-A in (a), and (c) is B in (b) Partial enlarged view. As shown in Figs. 1 and 2, the fumigant-filled container 1 of this embodiment is mainly composed of a metal container composed of a receiving portion 3 and a lid 2 which contain the fumigant 4. The upper cover 2 is provided with a central hole 7 of the ignition head 6 and a plurality of smoke spray holes (not shown) exposing the heating element 5 for ignition, and the heating of the heating element 5 equipped with the ignition is installed inside the upper cover 2.体 保护 板 8。 Body holding plate 8. A mounting hole 9 for mounting the heating element 5 for ignition is formed in the center of the heating element holding plate 8. A plurality of (in this embodiment, five) semicircular circles are formed at a peripheral portion of the mounting hole 9. Shaped dividing groove 1 0. Therefore, a plurality of support pieces 11 are formed at the peripheral portion of the mounting hole 9 separated by these dividing grooves 10 and bent at a certain angle (about 77 ° in this embodiment) above. Moreover, the bending angle of these support pieces is preferably less than 90 °, and more preferably more than 50 ° but less than 90 °. As described above, the plurality of support pieces 11 that are bent in a tapered shape can elastically expand the aperture when the ignition heating element 5 is mounted below the mounting hole 9, so that the ignition heating element 5 can be mounted with a small force. At the same time, it is possible to effectively support the ignition heating element 5 by using its elastic force after installation. Regarding this 12 312 / Invention Specification (Supplement) / 92-06 / 92107727 200305363, several test results will be used to explain it in more detail. Table 1 shows the insertion strength and deformation of the heating element holding plate when the heating element 5 for ignition is mounted on the heating element holding plate 8 of the present embodiment and a conventional heating element holding plate (a perforated metal plate and a raw metal plate are used). And the test results of the detachment strength of the installed heating element for ignition and whether there is detachment during ignition. The measurement methods of the insertion strength and the peeling strength in Table 1 are as follows. (Measurement of Insertion Strength) The maximum load required when the ignition heating element is inserted into the mounting hole of the heating element holding plate and measured at S t r 〇 g r a p h (test speed 100 m / m i η) at an appropriate position. (Measurement of peeling strength) It is necessary to make the heating element for ignition mounted on the heating element holding plate fall off the mounting hole (including the case where the heating element holding plate is deformed without falling off) measured by Strograph (test speed 100mm / min). Maximum load. 13 312 / Invention Specification (Supplement) / 92-06 / 92107727 200305363 丨 J detachment during ignition 戡 戡 Dodge detachment strength_ CO 00 〇〇 < N CO CSI 〇〇inch < x > Cj CO (N CD CO CD CN 2 00 1 rH ΙΟ Ο io ο 〇 Deformation during insertion m joint m medium m hiding insertion strength (kgf) CO 〇0 os 〇〇1 Ϊ 00 00 00 < N 〇1 oq c〇ίΩ Thickness (mm) 0.21 0.23 0.32 inch d inch d 0.24 0.28 Features of mounting holes f Ink painting ^ Qi, α · 酲 G 嫛 鹗 .S you 5 ^ 11 1 ^ 1?

Known technology 312 / Invention specification (Supplement) / 92-06 / 92107727 200305363 The board can not only install the ignition heating element 5 under a small load with a maximum insertion strength of not more than 196N (20kgf) and an average of 9 8 N (10kgf) or less, and it must be removed after installation. The required spring force should be 98N (10kgf) or more. Also, the deformation of the mounting hole 9 was not seen during insertion, and After installation, the heating element 5 for ignition is detached due to the burning action that is strongly pressed on the upper part of the ignition head 6. In the conventional technology, in the case of a perforated metal plate, the maximum insertion strength is 314N ( 32kg), which also requires an average of 225N (23kgf). Compared with the heating element holding plate of the present invention, a larger load is required when the ignition heating element 5 is installed. However, in the case of a raw metal plate, not only the maximum 274N is required. The load of (28kgf) is almost completely inelastic, so the peeling strength is ON (0kgf). The deformation of the mounting hole 9 during insertion and the case of falling off due to the ignition operation after installation all occur. This will be formed in this embodiment. The semi-circular cutouts are divided grooves. As long as the divided grooves can be separated at approximately equal intervals in the peripheral portion of the mounting hole 9, there is no particular limitation. The protruding portion formed by the support sheet and the recessed portion formed by the dividing groove may form a continuous wave shape. In addition, the heating body holding plate 8 of this embodiment is radiated around the mounting hole 9 as a center. A plurality of (15 in this embodiment) smoke injection holes 12 are formed on the ground. Ignition is performed by rubbing the ignition head 6 of the ignition heating element 5 with a friction plate or the like, and then the heating agent inside the ignition heating element is burned. When the fumigant 4 emits smoke due to the heat, the smoke spray holes 12 are the way to release the smoke. 15 312 / Invention Specification (Supplement) / 92-06 / 92107727 200305363 In this embodiment, 15 oval holes are formed as the smoke spray holes 12. The shape and number of such smoke spray holes 12 can be determined according to the amount of smoke Design appropriately. For example, the shape may be circular, rectangular, oval, or any combination thereof. The number can be about 1 to 30. In addition, in order to make the smoking agent-filled container 1 achieve a better smoking state, the total opening area of the smoke spray holes 12 and the opening area of a plurality of smoke spray holes (not shown) provided on the upper cover 2 are better. 1 ~ 8. In addition, a plurality of projecting rigid reinforcing portions 13 are formed in the same radial shape between the above-mentioned smoke spray holes 12, which effectively reduces the temperature of the heat-generating body holding plate 8 lowered by the formation of the plurality of smoke spray holes 12. Reinforcement in plane rigidity. Conventional heating element holding plates have generally used a metal plate having a thickness of 0.4 mm or more. However, by forming such a rigid reinforcing portion 13 at an appropriate position, a metal plate having a thickness of about 0.3 mm can be used. In this embodiment, the rigid reinforcing portions 13 are elliptical structures formed at five positions. However, the shape, position, and number of these rigid reinforcing portions 13 can be considered in consideration of the strength of the heating element holding plate itself and the use of ignition. Appropriate design after mounting and holding force of the heating element. However, in the case where a plurality of smoke injection holes are formed radially with the mounting hole 9 as the center in this embodiment, it is preferable to form a rigid reinforcing portion having the above-mentioned shape uniformly between the smoke injection holes, which can be extremely effective. The planar rigidity of the heating body holding plate is improved. The peripheral portion 14 of the heat generating body holding plate 8 is bent downward as shown in FIG. 2. In addition to being easily attached to the upper cover 2 of the heating-body holding plate 8, the peripheral portion 14 can also be prevented from falling off the upper cover 2 due to its elastic force. Therefore, for example, an adhesive or the like may be simultaneously applied to the peripheral portion 14 to fix it to the upper cover 2. 16 312 / Invention Specification (Supplement) / 92-06 / 92107727 200305363 As the ignition heating element 5 'held on the heating element holding plate of the present invention 5' As shown in FIG. 3, it is preferably connected with the heating element holding plate A plurality of protruding portions 16 are formed around the mounting portion 1 5 at regular intervals. Such a protruding portion 16 allows the ignition heating element 5 to be fitted into the mounting hole 9 of the heating element holding plate 8 more firmly. In this case, it is preferable that the number of these protruding portions 16 formed is larger than the number of the divided grooves 10 described above. According to such a design, when the ignition heating element 5 is mounted in the mounting hole 9 of the heating element holding plate 8, it is possible to ensure that the protruding portion 16 of the ignition heating element 5 and the above-mentioned division groove 10 are completely consistent with each other, regardless of whether or not the projection portion 16 of the ignition heating element 5 is completely consistent with each other. The ignition heating element 5 is held with a high holding force. As shown in FIG. 4, the fumigant-filled container as described above is housed in a state made of a synthetic resin or the like in a state in which a heat-resistant outer tube 17 made of a paper tube or the like is fitted. Use in a container 18. In addition, 19 in FIG. 4 is an upper lid of the exterior container 18. Hereinafter, a manufacturing method of the heat generating body holding plate of the present invention will be described with reference to FIG. 5. Fig. 5 shows an example of a method for continuously producing the heating element holding plate of the present invention, that is, an example of manufacturing the heating element holding plate 8 shown in Fig. 2. The features of the manufacturing method of the present invention will be described below in the order of steps. (First step) A mounting hole 9 is formed at the center in the width direction of the coil substrate 50, and there are five divided grooves 10 at approximately equal intervals in the periphery thereof, and five ellipses are formed radially with the mounting hole 9 as the center.形 烟 孔 1 2. Further, in this embodiment, in order to improve the feeding accuracy of the coil substrate 50, circular positioning holes 51 are simultaneously formed in the vicinity of both end portions of the substrate 50. These positioning holes 51 are provided with a guide pin with a sharpened tip on the upper die in a later step. While the punch slide is lowered, the guide pin is inserted into the positioning hole 51 to determine 17 312 of the coil material. Invention Specification (Supplement) / 92-06 / 92107727 200305363 position, improve feeding accuracy. When the tip of the guide pin is inserted into the positioning hole 51, the coil must be in a free state. At this time, the coil is held in the open state by the clamp of the feeding device. (Second step) The outer portion (peripheral portion 14) of the heating element holding plate and the peripheral portion of the mounting hole separated by the dividing groove 10 are bent into a cone shape in a certain direction to form a supporting sheet 11 at the same time. Five protrusions (rigid reinforcement 13) are formed radially around the mounting hole 9. (Third step) The remaining 10 smoke-spraying holes 12 are formed radially around the mounting hole 9. It is necessary to ensure that the smoke spray holes of the heating element holding plate have a certain area or more. The plurality of oval smoke spray holes formed in this embodiment are located close to each other. Therefore, if you want to demold all the smoke holes at one time, it may cause the problem of reduced mold durability. However, the durability of the mold can be improved by forming the plurality of smoke injection holes 12 as described above in the first step and the third step while maintaining a certain distance from each other. (Fourth step) The heat generating body holding plate located in the outer shape portion (peripheral portion 14) is extracted from the substrate 50. As a result, a heat generating body holding plate 8 as shown in Fig. 2 is obtained. In this way, according to the manufacturing method of the present invention, in particular, forming a plurality of smoke holes through the first step and the third step can simplify the mold structure used in each step and improve its durability. At the same time, since it is formed on the substrate in the first step, The mounting hole and a part of the smoke spray hole, in the second step, form a rigid reinforcing portion on the substrate so as to improve the planar rigidity of the substrate, so the deformation of the substrate can be prevented when the remaining smoke spray holes are formed in the third step. / Invention Specification (Supplements) / 92-06 / 92107727 200305363 Good manufacturing efficiency in designing products. Further, in the manufacturing method of the present invention, 'based on the hole diameter of the heating element holding plate produced, specifically, for example,' when the hole diameter of the heating element holding plate is large, the periphery of the mounting hole performed in the second step is performed. The bending of the part can also be performed in the third step. Therefore, it is possible to disperse the deformation caused to the substrate and improve the accuracy of the product size. According to the heat generating body holding plate of the present invention as described above, by forming the curved support sheet that can be elastically enlarged in diameter and separated by a plurality of divided grooves at substantially equal intervals, the periphery of the heat generating body for ignition can be uniformly supported. The support sheet capable of elastically expanding the aperture can absorb the force generated when the ignition heating element is installed, and the ignition heating element can be easily installed in the mounting hole of the heating element holding plate. The ignition heating element is held by a high holding force, so when the ignition head of the ignition heating element is rubbed with a friction plate or the like, the ignition heating element can be effectively prevented from falling out of the mounting hole. In addition, since there are a plurality of protrusions around the mounting portion where the ignition heating element is mounted on the heating element holding plate, the number of these protruding portions is larger than the number of divided grooves formed in the mounting hole peripheral portion of the heating element holding plate. In many cases, the above-mentioned protrusions fit the ignition heating element more firmly into the mounting hole of the heating element holding plate, so that the holding force of the ignition heating element can be more effectively improved. Furthermore, in particular, a plurality of smoke injection holes are formed around the mounting hole, for example, in a radial shape, and when protrusion-shaped rigid reinforcement portions such as ovals and rings are formed around the smoke injection holes, a plurality of smoke injection holes are formed. The planar rigidity of the heating element holding plate reduced by the smoke spray hole can be obtained from the above-mentioned protruding portion. 19 312 / Invention Specification (Supplement) / 92-06 / 92107727 200305363 effectively strengthens, making it possible to reduce the thickness of the heating element holding plate. And can reduce manufacturing costs. According to the manufacturing method of the heating body holding plate of the present invention, since the plurality of smoke spray holes are formed in the first step and the third step, respectively, the die structure used in each step can be simplified and the durability can be improved. On the substrate in which the mounting hole and a part of the smoke injection hole are formed in the first step, the planar rigidity of the substrate is improved by the rigid reinforcing portion formed in the second step, so that it is possible to prevent the formation of the remaining smoke injection holes in the third step. Deformation of the substrate, etc. In this way, it is possible to continuously manufacture a product conforming to the design in a small number of steps with good efficiency.
