如上述构成的常规PTC加热装置具有许多问题,将在后面予以阐述。 Such as a conventional PTC heating device constructed as described above have a number of problems, which will be explained later.

如上所述,常规的PTC加热装置500具有环形PTC热敏电阻80。 As described above, the conventional PTC heating device 500 has an annular PTC thermistor 80. 在制造这种环形PTC热敏电阻时,常规做法是用镍对整个PTC热电阻环形物体表面进行电镀,再进行热处理。 In the manufacture of such a PTC thermistor annular, conventional practice is to use nickel for the entire PTC thermistor annular surface plating, and then heat-treated. 然后,采用磨光技术将围绕着环形物体的通孔内壁上的镍膜去除。 Then, a polishing technique would surround the annular wall of the through hole of the object nickel film is removed. 但是,磨光工艺的确很麻烦。 However, polishing process is indeed a lot of trouble. 要去除镍膜需要足够的时间。 To remove the nickel film needs enough time. 因此,环形PTC热敏电阻就变得很贵。 Therefore, the ring PTC thermistor becomes expensive. 另一种方法是,可以用化学腐蚀来除掉内壁的镍膜。 Another method is chemical etching can be used to remove the inner wall of the nickel film. 但是,由于进行腐蚀要使用化学品,这将使环形物体和做在该环形物体上的电极劣化。 However, due to the etching to make chemicals, which will make the annular body and the annular body of the electrode is deteriorated.

而且,在常规的PTC加热装置中,壳体50的园筒部分52和经过园筒部分52上的径向膛孔52a插入的筒形热辐射件90沿着与PTC热电阻80的电极80a和80b的水平表面成直角的方向延伸,从而PTC加热装置500在实用时,由PTC热敏电阻80的电极80a和80b产生的热将经过若干条通路传导到作为用来加热已由吸液心吸上来的液体杀虫剂的装置的热辐射件90。 Further, in the conventional PTC heating device, the cylindrical portion 52 of the housing 50 and the cylindrical heat-radiating member through a radial bore 52 of the cylindrical portion 52a of the insert 90 along with the PTC thermistor and the electrodes 80a 80 The horizontal surface 80b extends in a direction at right angles to the PTC heating device 500 in practical use, the heat generated by the PTC thermistor electrode 80a 80 and 80b will be generated through several pathways, as transmitted to the wick for heating by suction up liquid insecticide thermal radiation of 90 pieces of equipment. 尤其是在常规的PTC加热装置中,PTC热敏电阻80的电极80a和80b的水平表面并不跟园筒部分52接触。 Especially in the conventional PTC heating device, PTC thermistor electrodes 80a and 80b are not in contact with the horizontal surface of the cylindrical portion 52 80. 而是分别通过上极板70和下极板60与盖板100和壳体50底部相接触,致使PTC加热装置500在使用时,由PTC热敏电阻80的电极80a和80b产生的热将通过上极板70和下极板60传导给盖板100和壳体50底端,然后再通过园筒部分52传导给热辐射件90。 But separately through plate 70 and the lower plate 60 and the cover plate 100 and the bottom housing 50 is in contact, so that the PTC heating device 500, in use, heat generated by the PTC thermistor electrode 80a 80 and 80b generated by upper plate 70 and lower plate 60 is conducted to the bottom of the cover 100 and the housing 50, and then transfer to the heat radiating member 90 through the cylindrical portion 52. 因此,在常规PTC加热装置中,将花费很长时间使热辐射件90加热到足以蒸发液体杀虫剂的温度。 Therefore, in the conventional PTC heating device, it will take a long time to make the heat radiation member 90 is heated to a temperature sufficient to vaporize the liquid insecticide.

同样,类似于上述常规PTC加热装置并用作加热器来防止供水管等产生冰冻的一种筒形恒温加热装置被公布在日本专利公开公报第35490/1985号上。 Also, similar to the above-described conventional PTC heating device and used as a heater to prevent heated water tubes to produce tubular heating means is frozen on the published Japanese Patent Publication No. 35490/1985. 图3和图4表示了这种恒温加热器。 Figures 3 and 4 shows such a heater thermostat. 在图3和图4中,与图2中所示相同的部件标上了同样的标号,对它们的描述也不再重复。 In Figures 3 and 4, the same components shown in Figure 2 are denoted by the same reference numerals, and their description are not repeated. 参考号300表示通过焊剂或导电粘接剂302连接在PTC热敏电阻80的上电极80a上的引线。 Reference numeral 300 denotes a connection lead to the PTC thermistor of the upper electrode 80a 80 by solder or conductive adhesive 302. 参考号400表示通过焊剂或导电粘接剂402连接在PTC热敏电阻80的下电极80b上的引线。 Reference numeral 400 indicates the connection to the PTC thermistor of the lower electrode 80b 80 by solder or conductive adhesive 402 lead. 这种恒温加热器也有前面所说的问题。 This heater thermostat also has the previously mentioned problems.

图9-12示出第一实施例的一个改进方案。 Figure 9-12 shows a modification of the first embodiment. 在图9-12的方案中,与图5-8中相同的部分用相同的符号表示,对它们的描述将不再重复。 In the scheme of Figure 9-12, and Figures 5-8 the same parts designated by the same reference numerals, and the description thereof will not be repeated. 随便提一句,在图9中,为叙述清楚起见,该方案中各部分上下颠倒示出。 Casually mention that in Figure 9, for narrative clarity, each part of the program is shown upside down. 实际上PTC加热装置相对于电灭蚊器的安装是如图10所示的。 Indeed PTC heating device with respect to the electric mosquito destroyer the installation is shown in Fig. 10.

现在参考图9-12,第一电极部件60的侧板64在其上沿和下沿上有弯曲部分64a和64b,它们相对于平面侧板64被弯曲成适当的角度并向侧板64上的PTC热敏电阻80延伸。 Referring now to Figure 9-12, the first electrode member 60 of the side plate 64 has bent portions 64a and 64b on its upper edge and a lower edge, which with respect to the plane of the side plate 64 on the side plate 64 is bent to an appropriate angle The PTC thermistor 80 extends. 与侧板64相同,第一电极部件60的侧板65在其上沿和下沿上有弯曲部分65a和65b,它们相对于平面侧板65被弯曲成适当的角度并向侧板65上的PTC热敏电阻81延伸。 The same as the side plate 64, the first electrode member 60 on the side plate 65 at its upper edge and a lower edge bent portion 65a and 65b, which with respect to the plane of the side plate 65 is bent to the appropriate angle to the side plate 65 of PTC thermistor 81 extends. 第一电极部件60通常由不锈钢或类似材料的片冲压而成,这样会在侧板64和65上产生毛刺。 The first electrode member 60 is generally made of stainless steel or sheet stamping similar material from, this will produce burr in the side plates 64 and 65. 若在第一电极部件60的侧板64和65上确实存在着毛刺,则当PTC热敏电阻80和81分别装配在第一电极部件60的侧板64和65上时,它们挨在这些毛刺上,从而使它们不能分别与侧板64和65紧密接触,减弱了从PTC热敏电阻80和81到热辐射件90的高效而迅速的热传递。 If the first electrode member 60 on the side plate 64 and the burr 65 does exist, then when the PTC thermistors 80 and 81 are fitted on the first electrode member 60 of the side plates 64 and 65, they suffer in these glitches on, respectively, so that they can not be brought into close contact with the side plates 64 and 65, reduced heat transfer from PTC thermistors 80 and 81 to the heat radiating member 90 is efficient and rapid. 在图9-12的改进方案中,这些毛刺被弯曲部分64a、64b、65a及65b吸收了,从而使PTC热敏电阻80和81可以与第一电极部件60的侧板64和65紧密接触在一起。 In FIG improved scheme 9-12, these burrs are bent portions 64a, 64b, 65a and 65b absorbed, so that the PTC thermistors 80 and 81 may be in close contact with the first electrode member 60 of the side plates 64 and 65 together.

图22表示电灭蚊器的一个纵剖面图,该灭蚊器中结合有图15所示的PTC加热装置500。 Figure 22 shows an electric mosquito destroyer vertical sectional view of a mosquito incorporating a PTC heating device shown in FIG. 15 500.

参见图22,该电灭蚊器包括一个具有在其上壁40b上形成通孔40a的上防护套40以及一个下防护套42,下防护套42有一个支撑部分48来支持PTC加热装置500在其中通过,该装置500安装在下防护套42的内部。 Referring to Figure 22, the electric mosquito destroyer comprises an upper wall having at its 40b formed on the through hole 40a of the safety cover 40 and a lower protective cover 42, under the protective cover 42 has a supporting portion 48 to support the PTC heating device 500 in through which the device 500 is mounted inside the lower protective sleeve 42. 在图22中参考号44标示一个盛有液体杀虫剂的储液器。 In Figure 22, the reference number 44 filled with a liquid insecticide labeled an accumulator. 参考号46标示一个吸液心,该吸液心用以从储液器44中吸取液体杀虫剂,它是一个毛毡类纤维材料或多孔材料制成的细长体。 Reference numeral 46 indicated a wick, the wick to draw liquid insecticide from the reservoir 44, which is a fiber material of felt or porous material made of an elongated body. 细长形吸液心46通过储液器44的嘴插入储液器44以使其浸入储液器44所盛的杀虫剂液体内,细长形吸液心46的上端部由储液器44的嘴内伸出并插入PTC加热装置500的热辐射器90中的镗孔92之中。 An elongated wick 46 is inserted through the mouth accumulator 44 the accumulator 44 so that it is immersed in the liquid insecticide containing the accumulator 44, the upper end portion of an elongated fluid absorbent core 46 by the accumulator projecting mouth 44 and inserting the PTC heating device 500 of the heat radiating member 90 in the bore 92 into. 支撑部分48由一个具有通孔48b的平板48a所构成。 Support portion 48 consists of a flat plate having a through hole 48b constituted 48a.
