Abstract
The utility model relates to hair dryer technical field; refer in particular to a kind of electronic circuit for hair dryer, form primarily of switch, fuse, press button, coil, secured core, armature core, spring, overtemperature protection I, overtemperature protection II, main contact I, main contact II and auxiliary contact.A connector lug of described main contact I is connected with overtemperature protection I, and another connector lug is connected with fan, and a connector lug of described main contact II is connected with overtemperature protection II, and another connector lug is connected with heating wire.Described coil is around on described secured core, and when described coil electricity, described secured core produces magnetic field.When described armature core is by the magnetic field suction of described secured core, the pull bar on described armature core pulls described main contact I, described main contact II and described auxiliary contact and makes their conductings separately.Described hair dryer have a power failure again calling protection circuit for hair dryer can be made during hair dryer to have and send a telegram here again time be in the defencive function of off position.
Description
Technical field
The utility model relates to hair dryer technical field; refer in particular to a kind of electronic circuit for hair dryer; user's prominent chance when using hair dryer has a power failure and forgets and close swap switch or pulled up from socket by hair dryer power-line plug, and the hair dryer played a protective role when hair dryer being made to be in off position after incoming call again has a power failure calling protection circuit again.
Background technology
Hair dryer is a kind of very conventional household electrical appliance, in the process using hair dryer, when prominent chance has a power failure, turn off switch of hair drier because the reason users such as carelessness may forget or hair dryer power-line plug is pulled up from socket, after again sending a telegram here, hair dryer will work on, the hot blast that hair dryer is produced by boasting likely blows to inflammable material around and initiation fire for a long time, causes damage to the lives and properties of the people.
Utility model content
In order to solve the problem, the utility model provides a kind of hair dryer to have a power failure calling protection circuit again, for hair dryer, hair dryer can be made to run in the course of the work when power failure is sent a telegram here again and have the defencive function being in off position.
The technical scheme that the utility model adopts is:
The described hair dryer calling protection circuit that has a power failure again is formed primarily of switch, fuse, press button, coil, secured core, armature core, spring, overtemperature protection I, overtemperature protection II, main contact I, main contact II and auxiliary contact.Described press button is normal open switch, and momentary connection when clicking, disconnects after loosing one's grip immediately.A connector lug of described main contact I is connected with overtemperature protection I, and another connector lug is connected with fan, and a connector lug of described main contact II is connected with overtemperature protection II, and another connector lug is connected with heating wire.Described coil is around on described secured core, and when described coil electricity, described secured core produces magnetic field.Described spring is extension spring.One end of two described springs is fixed, the other end is connected with described armature core, described armature core there is pull bar, when described armature core is by the magnetic field suction of described secured core, the pull bar on described armature core pulls described main contact I, described main contact II and described auxiliary contact and makes their conductings separately.
The beneficial effects of the utility model are:
Described hair dryer have a power failure again calling protection circuit for hair dryer can be made during hair dryer to have and send a telegram here again time be in the defencive function of off position.
Accompanying drawing explanation
Further illustrate below in conjunction with figure of the present utility model:
Fig. 1 is structural representation of the present utility model.
In figure, 1. switch, 2. fuse, 3. press button, 4. coil, 5. secured core, 6. armature core, 7. spring, 8. overtemperature protection I, 9. overtemperature protection II, 10. main contact I, 11. main contact II, 12. auxiliary contacts, 13. fans, 14. heating wire.
Detailed description of the invention
The described hair dryer calling protection circuit that has a power failure again is formed primarily of described switch (1), described fuse (2), described press button (3), described coil (4), described secured core (5), described armature core (6), described spring (7), described overtemperature protection I (8), described overtemperature protection II (9), described main contact I (10), described main contact II (11) and described auxiliary contact (12).Described press button (3) is normal open switch, and momentary connection when clicking, disconnects after loosing one's grip immediately.A connector lug of described main contact I (10) is connected with described overtemperature protection I (8); another connector lug is connected with described fan (13); a connector lug of described main contact II (11) is connected with described overtemperature protection II (9), and another connector lug is connected with described heating wire (14).Described coil (4) is around on described secured core (5), and when described coil (4) is energized, described secured core (5) produces magnetic field.Described spring (7) is extension spring.One end of two described springs (7) is fixed, the other end is connected with described armature core (6), described armature core (6) there is pull bar, when described armature core (6) is by the magnetic field suction of described secured core (5), main contact I (10), described main contact II (11) and described auxiliary contact (12) described in pull bar stretchy also make their conductings separately.
During use, close described switch (1), click described press button (3), described press button (3) momentary connection, described coil (4) is energized, described secured core (5) produces magnetic field, attract described armature core (6) together with the pull bar on described armature core (6), under the pulling of pull bar, described main contact I (10), described main contact II (11) and described auxiliary contact (12) are connected all simultaneously, now unclamp described press button (3), described press button (3) disconnects immediately, because described auxiliary contact (12) is connected, described coil (4) continues energising, described secured core (5) continues to produce magnetic field, continue to attract described armature core (6) together with the pull bar on described armature core (6), described main contact I (10), described main contact II (11) and described auxiliary contact (12) all continue to connect, hair dryer works.When having a power failure, hair dryer quits work, and turns off switch of hair drier if user forgets or is pulled up from socket by the plug of hair dryer, then can not automatic operation because described press button (3) disconnects when sending a telegram here, and plays a very good protection.Now, if make hair dryer rework, click described press button (3).
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and amendment to above-mentioned embodiment.Therefore, the utility model is not limited to the detailed description of the invention disclosed above, within the protection domain that also should fall into claim of the present utility model to modifications and changes more of the present utility model.In addition, although employ some specific terms in this description, these terms just for convenience of description, do not form any restriction to the utility model.
