Embodiment
As shown in Figure 1, the utility model heater is provided with a heating main casing 10, described heating main casing 10 also connects combination one peripheral circuit control body 20, heating wire or heating film (not shown) is wound around for this hollow tube periphery in the inner predeterminable hollow tube of heating main casing 10, after making water can send into heating by heating main casing 10 one end 11, sent the warm water heated by another end 12; Described peripheral circuit controls body 20 can locate a circuit board 21 in assembled inside; preset relevant heating control circuit 22 (attached ginseng Fig. 5) for this circuit board 21, described heating control circuit 22 can arrange an angle inductive switch 23 and at least one water enter preventing circuit arrangement 24 further.Described by heating main casing 10 and connect combination peripheral circuit control the heater that jointly forms of body 20 thus can as shown in Figure 2 as insert in water 30 with an above-below direction fixed and set angle.
As shown in Figure 3, described angle inductive switch 23 can be just like illustrated ball angle inductor, the movable steel ball 231 of a setting size diameter is provided with in inside, described steel ball 231 normality is positioned at a scalene cone 232 preset, described steel ball 231 is because naturally drooping the impact of gravity, and normal contact is preset the wherein contact 233 of conductive junction points and another contact 234 to two and become normal conduction.But when whole heater exceed set angle (as 45 °) become improper installing state time; described steel ball 231 only will contact wherein a contact 233 (as diagram is tilted to the left as 45 °) or another contact 234 (as diagram is tilted to the right as 45 °) as diagram; and by heater power-off, safeguard protection effect can be formed.Meanwhile, as shown in Figure 4, when whole heater is not according to prescribed direction installing, and when being as illustrated reverse installing, described steel ball 231 will roll and depart from contact 233 and another contact 234 simultaneously, can become power-off protection state equally.
As shown in Figure 5, described water enter preventing circuit arrangement 24 can be the water enter preventing circuit 25 that is located at described heating control circuit 22, this water enter preventing circuit 25 is provided with a water inlet inductive switch 26 and connects a comparator circuit 27, this comparator circuit 27 compares pin potential difference by a diode (D4B), and be electrically connected the interchange thyristor (Q2) of the non-conducting of a normality, be electrically connected to an automatic power-off protection device 28 again, described automatic power-off protection device 28 comprises the resistance (R7 of electric connection, and a Thermal Cutoffs (F1) R8), for forming sensing function more accurately, please also refer to Fig. 2 A and Fig. 5, described resistance (R7, R8) and Thermal Cutoffs (F1) can pass through described circuit board 21 and make and integrally carry out temperature-sensitive and sealed and carry out temperature-sensitive.When described water inlet inductive switch 26 senses into water generation resistance variations; this comparator circuit 27 starts automatic power-off protection device 28 described in the conducting of described interchange thyristor (Q2); make resistance (R7, R8) heating up because resistance is increased; blow described Thermal Cutoffs (F1), whole down circuitry is become safeguard protection state.
