现在参见图1，为了便于理解本发明，将更详细地对配备有PTC加热装置的电灭蚊器进行描述。 Referring now to Figure 1, in order to facilitate understanding of the present invention, in more detail on the electric mosquito destroyer equipped with PTC heating device will be described. 电灭蚊器包括两个互相吻合的上部和下部防护壳40和42及盛有液体杀虫剂的容器44。 Electric mosquito protection, including upper and lower case are consistent both 40 and 42 and filled with a liquid insecticide container 44. 容器44置于下部防护壳42之中。 44 placed in the lower part of the container 42 into the protective shell. 上部防护壳40在其顶壁40b上有一孔40a;并在其侧壁内表面有整体形成的套座部40c。 An upper protective housing 40 has a hole 40a on its top wall 40b; and the inner surface of the socket side wall portion integrally formed 40c. 如上所述，电灭蚊器进一步包括PTC加热装置500。 As mentioned above, electric mosquito PTC heating device further comprises 500. 加热装置500包括一壳体50和装于该壳体50上的园筒形热辐射件90（见图2），这将在后面详细描述。 Heating means 500 includes a housing 50 and the housing 50 is mounted on the cylindrical heat-radiating member 90 (see FIG. 2), which will be described later in detail. PTC加热装置500是以这样一种方式装在上部防护壳40上的，即其壳体50部分地镶入上部防护壳40的相应套座部40c中。 PTC heating device 500 is mounted in such a manner that the upper armoring case 40, i.e., part of the housing 50 to insert it into the upper armoring case 40 of the socket portion 40c of the corresponding. 图1中，参考号46表示吸液心，用于将液体杀虫剂从容器44中吸上来。 1, reference numeral 46 denotes the wick for sucking up liquid insecticide from the container 44. 如前所述，吸液心46是由毡类纤维材料或多孔材料制成的细长体。 As described above, the wick 46 is made of fibrous material such as felt, or porous material of the elongate body. 细长的吸液心46通过容器44的开口插入容器44中，并被浸泡在容器44中的液体杀虫剂中。 Elongated wick 46 is inserted through the opening 44 of the container 44 in the container, and is immersed in the liquid vessel 44 insecticides. 细长的吸液心46的上部伸出容器44的开口。 The upper portion of the elongated wick 46 is projected opening of the container 44. 装有PTC加热装置500的上部防护壳40和下部防护壳42以这样一种形式相互吻合，即使细长的吸液心46的上端部穿过园筒形热辐射件90的径向膛孔92（见图1和图2）。 PTC heating device is equipped with an upper portion 500 of the protective shell 40 and the lower armoring case 42 coincide with each other in such a form, even if the radial bore an elongated absorbent core 46 of the upper end portion of the liquid passing through the cylindrical heat-radiating member 90 of 92 (see Figures 1 and 2).
在如上述构成的电灭蚊器中，当设在PTC加热装置500中（后面将详叙）的PTC热敏电阻产生热量时，产生的热量被传导到热辐射件90上，已从容器44中吸取了液体杀虫剂的吸液心46的上端部由已传给热辐射件90上的热量加热，使液体农药蒸发。 In the above electric mosquito destroyer constructed, when provided in the PTC heating device 500 (described later in detail Syria) PTC thermistor to generate heat, the heat generated is conducted to the heat radiation member 90, 44 from the container draw the upper end portion of the wick 46 by the liquid insecticide is heated with the heat transmitted to the heat radiating member 90 on the liquid pesticide and evaporated. 这样，蒸发出来的杀虫剂经过上部防护壳40的通孔40a散布到电灭蚊器的外部。 Thus, the vaporized insecticide through the upper armoring case 40 through hole 40a of the electric mosquito destroyer spread outside.
参见图2，常规的PTC加热装置500包括一个在上极板70和下极板60之间垂直放置的PTC热敏电阻80，具有槽51的壳体50，和园筒形热辐射件90。 Referring to Figure 2, a conventional PTC heating device 500 comprises a vertically disposed between the plates 70 and the lower plate 60 of the PTC thermistor 80, the groove 51 having a housing 50, and a cylindrical heat radiation member 90.

PTC热敏电阻80和极板70和60被置于壳体50的凹槽51中，分别经过通孔82，72和62与壳体50的园筒部52相吻合。 PTC thermistors 80 and plates 70 and 60 are disposed in the recess 51 of the housing 50, respectively, through the through holes 82,72 and 62 and the cylindrical portion 52 of the housing 50 coincide. 图2中，100表示一盖板。 Figure 2, reference numeral 100 denotes a cover plate. 盖板100由耐热塑料制成，并有一通孔101，盖板100放置在上极板70上，使其通孔101与壳体50的园筒部分52的膛孔52a对准，从而堵住了壳体50的凹槽51。 Cover 100 is made from heat-resistant plastic and has a through hole 101, the cover plate 100 placed on the upper plate 70, the cylindrical through-hole 101 so that the housing 50 of the bore 52a aligned portion 52, thereby blocking live grooves 51 of the housing 50. 筒形热辐射件90由铝一类的金属制成，并在其一端设置有凸缘91。 Cylindrical heat radiation member 90 made of aluminum a metal such as steel and provided with a flange at one end 91. 热辐射件90安装在壳体50上。 Heat radiation member 90 is mounted on the housing 50. 方式是将其插入盖板100的通孔101和壳体50的园筒部52的径向膛孔52a，并将其另一端铆接在壳体50的外部底面上。 Way is to insert it into the through-hole 100 of the cover 101 and the housing cylindrical portion 50 of the radial bore 52a 52, and the other end riveted on the external surface of the casing 50 of the bottom.
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.
