Technical field
The utility model relates to the switch of hair dryer; especially a kind of motor in hair dryer inside breaks down in the time of can not drying; can automatic disconnection the resistance wire power supply of hair dryer inside make it not generate heat, thereby the hair dryer safety switching apparatus of the protective effect that hair dryer is played.
Background technology
At present, known hair dryer, after turning on the power switch, inner motor and resistance wire can be together electric work, break down at motor and not dry, when the user did not have timely powered-down switch, the heat of resistance wire generation can burn out hair dryer.
The utility model content
The utility model purpose is to overcome existing hair dryer; after turning on the power switch; inner motor and resistance wire can be together electric work; break down at motor and not dry; when the user does not have timely powered-down switch; the heat that resistance wire produces can burn out hair dryer; provide a kind of motor in hair dryer inside to break down in the time of to dry; can automatic disconnection the resistance wire power supply of hair dryer inside make it not generate heat, thereby the hair dryer safety switching apparatus of the protective effect that hair dryer is played.
The purpose of this utility model is achieved in that
The hair dryer safety switching apparatus, it is characterized in that by base plate, chute, last magnet, lower magnet, spring, shell, tongue tube and temperature detect switch (TDS) constitute, all elements are installed in hair dryer inside, there is a circular hole at the center of base plate, chute has four, four chutes are installed on the base plate, last magnet, lower end the right and left of lower magnet respectively has a slide bar, last magnet, the jack rod sleeve of lower magnet is in four chutes, spring has two, wherein an end of a spring is installed in the base plate upper end, and the other end is installed in the magnet lower end, and an end of another spring is installed in the base plate lower end, the other end is installed in the lower magnet lower end, tongue tube is connected by lead with temperature detect switch (TDS), and tongue tube is installed in enclosure, and temperature detect switch (TDS) is installed on the shell.
Described base plate is rectangle plastics materials.
Described shell is plastic material.
Described temperature detect switch (TDS) is aluminum shell 85 ℃ of temperature switches Celsius.
When the utility model uses, when the motor internal of hair dryer can not turn round blowing because of fault, the resistance wire power supply of energy automatic disconnection hair dryer inside made it not generate heat, thereby avoid because electrical fault can not be dried, cause the rising of resistance wire temperature and send a telegraph the blowing damage.
Description of drawings
Fig. 1 is structural representation of the present utility model; Fig. 2 is the circuit diagram between the resistance wire of magnet on the utility model, lower magnet, tongue tube, temperature detect switch (TDS) and hair dryer inside.
The specific embodiment
Shown in Fig. 1, the hair dryer safety switching apparatus, by base plate 1, chute 2, last magnet 3, lower magnet 4, spring 5, shell 6, tongue tube 7 and temperature detect switch (TDS) 8 constitute, all elements are installed in hair dryer inside, there is a circular hole 1-1 at the center of base plate 1, chute 2 has four, four chutes 2 are installed on the base plate 1, last magnet 3, lower end the right and left of lower magnet 4 respectively has a slide bar, last magnet 3, the jack rod sleeve of lower magnet 4 is in four chutes 2, and spring 5 has two, and wherein an end of a spring 5 is installed in base plate 1 upper end, the other end is installed in magnet 3 lower ends, one end of another spring 5 is installed in base plate 1 lower end, and the other end is installed in lower magnet 4 lower ends, and tongue tube 7 and temperature detect switch (TDS) 8 are connected by lead, tongue tube 7 is installed in shell 6 inside, and temperature detect switch (TDS) 8 is installed on the shell 6.Base plate 1 is rectangle plastics materials.Shell 6 is plastic material.Temperature detect switch (TDS) 8 is aluminum shell 85 ℃ of temperature switches Celsius.The utility model is enclosed within the circular hole 1-1 at base plate 1 center the motor shaft rear end of hair dryer inside; Shell 6 is installed in the inner correct position of hair dryer; After installing, tongue tube 7 and last magnet 3, lower magnet 4 are in same plane, 0.5 centimetre at interval of tongue tube 7 and last magnet 3, lower magnet 4.When using hair dryer, when the motor of hair dryer inside gets the electric operation blowing, be installed in the base plate 1 of motor shaft rear end and the last magnet 3, the lower magnet 4 that are installed on the base plate 1 also can turn round thereupon; Because action of centrifugal force, when rotating to a certain degree, last magnet 3, lower magnet 4 can overcome the pulling force of spring 5, the slide bar of last magnet 3, lower magnet 4 lower end the right and lefts can be outwards mobile along four chutes 2, so, last magnet 3, lower magnet 4 can approach and be in conplane tongue tube 7 with it, and tongue tube 7 is under the magnetic action power of last magnet 3, lower magnet 4, and the inside normally opened contact of tongue tube 7 can be connected; Because the resistance wire of hair dryer inside, one utmost point of its working power 220V AC power is to import through the inside of tongue tube 7 normally opened contact from temperature detect switch (TDS), so, after the inside normally opened contact of tongue tube 7 is connected, resistance wire can get electric work heating, and hair dryer also just can operate as normal.In use because some faults, when causing the hair dryer motor internal can not get the electric operation blowing, the base plate 1 that is installed in the motor shaft rear end can not turn round yet, last magnet 3, lower magnet 4 are kept off tongue tube 7 under the pulling force effect of spring 5, the resistance wire of hair dryer inside also just can not get electric work, so just can prevent because electrical fault can not be dried, cause the rising of resistance wire temperature and send a telegraph the blowing damage.
In Fig. 2, CT1 goes up magnet, and CT2 is lower magnet, and GH is tongue tube, and KT is temperature detect switch (TDS), and RL is the resistance wire of hair dryer inside.When the motor operate as normal blowing of hair dryer inside, last magnet CT1, lower magnet CT2 can be near tongue tube GH under action of centrifugal force, so the inside normally opened contact of tongue tube GH can be connected under the magnetic action power of last magnet CT1, lower magnet CT2, because the resistance wire RL of hair dryer inside, one utmost point of its working power 220V AC power is to import through the inside of tongue tube GH normally opened contact from temperature detect switch (TDS) KT, so, after the inside normally opened contact of tongue tube GH is connected, the resistance wire RL of hair dryer inside can get electric work heating, and hair dryer also just can operate as normal.When the hair dryer motor internal can not get the electric operation blowing owing to fault, the base plate that is installed in the motor shaft rear end can not turn round yet, last magnet CT1, lower magnet CT2 keep off tongue tube GH under the pulling force effect of spring, the resistance wire RL of hair dryer inside also just can not get electric work, so just can prevent because electrical fault can not be dried, cause the resistance wire RL temperature rising of hair dryer inside and send a telegraph the blowing damage.The effect of temperature detect switch (TDS) KT is that the resistance wire RL power supply of automatic disconnection hair dryer inside plays a protective role when the inner because unexpected temperature of hair dryer raises.In Fig. 2, tongue tube GH adopts JAG-3 type normally opened contact tongue tube.
