壳体50由阻热塑料材料制成,并包括具有凹槽51的一个基体和与该基体整体形成的,作为导热部分的园筒部52,从而筒部52从槽51外部底面的中央部位向上伸出。 Casing 50 of heat-resistant plastic material, and comprises a substrate having a recess 51 and formed integrally with the substrate as the conductive portion of the cylindrical portion 52, so that the cylindrical portion 52 from the bottom surface of the groove 51 outside of the center portion of upwardly extend.

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,具体做法是用镍对整个PTC热电阻环形物体进行无电镀,再进行热处理。 In the manufacture of such a ring PTC thermistor, which would be used for the entire PTC thermistor nickel ring objects electroless plating, and then subjected to heat treatment. 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,可以用化学腐蚀来除掉内壁的镍膜。 Another method, 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52和经过园筒部52上的径向镗孔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汲取器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 and a cylindrical heat-radiating member through a radial bore 52 on the cylindrical portion 52a of the housing 50 is inserted into the electrode 80a 90 along with the PTC thermistor 80 and 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 device for heating the sucked up by the draw liquid insecticide thermal radiation of 90 pieces of equipment. 尤其是,在常规的PTC加热装置中,PTC热电阻80的电极80a和80b的水平表面并不跟园筒部52接触。 In particular, in the conventional PTC heating device, PTC thermistor electrode 80a 80 and the horizontal surface 80b is not in contact with the cylindrical portion 52. 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热电阻80的电板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52传导给热辐射件90。 But separately through the upper plate 70 and lower plate 60 and the cover plate 100 and the bottom housing 50 is in contact, resulting in the use of thermal device 500, the PTC thermistor 80 of the plate 80a and 80b generated by PTC heating through the plate 70 and the 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 a cylindrical constant temperature water supply tube produced frozen heating means are published in the 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烈敏电阻80的上电极80a上的引线。 Reference numeral 300 denotes a connection lead 80 of the PTC resistor sensitizers on the upper electrode 80a 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.

本发明正是基于要克服前面所说先有技术装置的种种问题而做出的。 The present invention is based on overcoming the aforesaid problems of the prior art devices which made.
