Description
Technical field
The utility model is related to consumer goods industries, and in particular to a kind of hair-dryer of anti-scald hair.
Background technology
Hair-dryer is mainly used in the drying and shaping of hair, also is available for the side such as laboratory, psyciotherapy room and industrial production, art designing
Make local desiccation, heating and physiotherapy and be used in face.It is typically what is combined by one group of heating wire and a small fan.It is powered
When, heating wire can produce heat, and the wind of fan blowout passes through heating wire, reforms into hot blast.Hair-dryer is when in use, it is necessary to always
Rock, otherwise being blown always against somewhere hair can cause hair to overheat and scald.
Utility model content
The technical problem that the utility model is solved is to provide a kind of hair-dryer of anti-scald hair, it is to avoid hair-dryer is scalded
Hair.
To solve the above problems, the utility model employs following technical scheme：
A kind of hair-dryer of anti-scald hair, including hair-dryer body and located at intrinsic fan, heating unit and wind
Electromechanical road, the fan circuit is provided with vibration switch mould by attaching plug power taking between the fan circuit and attaching plug
Block, the vibration switch module includes voltage conversion unit, vibration switch, electric capacity, resistance, relay coil and relay normally open
Contact；With the electric capacity after the input connection power line of the voltage conversion unit, the relay coil and resistant series
Parallel connection, is serially connected with the output end of voltage conversion unit with the vibration switch afterwards, and the relay normally open contact is located at blower fan
On power line before circuit input end, and it is corresponding with the relay coil.
It is preferred that, the vibration switch is spring vibration switch.
The hair-dryer of anti-scald hair of the present utility model, is provided with vibration switch mould before the circuit of existing hair-dryer
Block, detects whether hair-dryer is rocking by the vibration switch in the module.Vibration switch when static equivalent to open circuit,
Equivalent to short circuit when rocking.Therefore, can be by vibration switch come the conducting and disconnection of control relay coil, and then control relay
The closed and disconnected of device normally open contact, so as to control the conducting and disconnection of air blower circuit.The resistance connected with relay coil
Play partial pressure, electric capacity in parallel plays time-lag action, and circuit will not disconnect when vibrations time interval very little.Vibration switch
It is preferred that use spring vibration switch, make the vibration switch module sensitiveer to the detection rocked.Using above-mentioned design, sheet
The hair-dryer of utility model stop rock when can auto power off, prevent hair because long-time blow scald.
Brief description of the drawings
Fig. 1 is the circuit connection diagram of the hair-dryer of anti-scald hair of the present utility model.
Fig. 2 is the structural representation of spring vibration switch.
Embodiment
For a further understanding of the utility model, the utility model preferred embodiment is retouched with reference to embodiment
State, but it is to be understood that these descriptions are simply to further illustrate feature and advantage of the present utility model, rather than to this practicality
The limitation of new claim.
The utility model provides a kind of hair-dryer of anti-scald hair, and it is provided with shake before the circuit of existing hair-dryer
Dynamic switch module, with the auto power off when hair-dryer is static.
Specifically, as shown in figure 1, the vibration switch module includes voltage conversion unit 2, vibration switch 4, resistance 5, electric capacity
6th, relay coil 3 and relay normally open contact 7.Wherein, the input of voltage conversion unit 2 is connected to behind attaching plug 1
Power line on, for 220V alternating current to be converted into 12V direct currents.With electric capacity 6 after relay coil 3 and the series connection of resistance 5
Parallel connection, is serially connected with the output end of voltage conversion unit 2 with vibration switch 4 afterwards.Relay normally open contact 7 is arranged on attaching plug
On power line between 1 and fan circuit 8, and after the joint of voltage conversion unit 2 and power line.The relay normally open
Contact 7 and relay coil 3 are corresponding, and its break-make is controlled by relay coil 3.
During work, whether vibration switch detection hair-dryer is rocking.Vibration switch is equivalent to open circuit when hair-dryer is static,
Equivalent to short circuit when hair-dryer is rocked.When vibration switch is short-circuit, relay coil conducting, so as to attract relay normally open contact to close
Close, turn on blower power.Conversely, when hair-dryer is static, relay coil disconnects, then relay normally open contact is opened,
Blower power disconnects.Meanwhile, the electric capacity in parallel with relay coil plays time-lag action, when vibrations time interval very little
It will not disconnect.
Preferably, vibration switch selects spring vibration switch in the present embodiment.It is illustrated in figure 2 spring shake
A kind of common type of dynamic switch, it includes being provided with power spring 42 in contact tube 41, contact tube 41, and power spring 42 leads to
The colloid 43 crossed at the mouth of pipe of contact tube 41 is installed in copper pipe, and conductive connecting pin 44a, 44b connect contact tube 41 and led respectively
Electrical spring 42, for accessing circuit.Above-mentioned spring vibration switch, can more sensitively detect rocking for hair-dryer, so that
Can hair-dryer stop rock when disconnecting circuit, realize the utility model technique effect to be reached.
The explanation of above example is only intended to help and understands method of the present utility model and its core concept.It should refer to
Go out, for those skilled in the art, can also be to this on the premise of the utility model principle is not departed from
Utility model carries out some improvement and modification, and these are improved and modification also falls into the utility model scope of the claims
It is interior.
