Specific embodiment
Referring to figs. 1 to Fig. 9, the present invention will be further described.
As seen in figs. 5-6, a kind of constant temperature seat ring, including seat ring base 6, the seat ring base 6, which has been sequentially arranged above, to be added
Thermosphere and insulating layer 8, the heating layer are the heating film 7 above seat ring base 6, further include for powering to heating film 7
Safety Extra Low Voltage DC power supply, the voltage of preferred Safety Extra Low Voltage DC power supply is 12-24V, using the electricity of safety
Range is pressed, can either guarantee that heating film 7 generates heat enough, keep heating temperature on raceway surfaces i.e. insulating layer 8 enough, while can disappear
Except user's electric shock feared state of mind, achieve the purpose that safer.
Wherein seat ring base 6 is passed through on the surface of present cycle basis layer 6 by the thermoplastic materials single injection-molded such as PP, ABS
Printing technology is upper by electrocondution slurry printing and forms heating film 7, encloses insulating materials again after electrocondution slurry solidification and forms insulation
Layer 8.
The heating film 7 being formed by curing in the present invention using electrocondution slurry is heated, heating film 7 compared to the prior art in
The combination thickness of heating wire and insulated hull substantially reduces, and the heating region of heating film 7 and raceway surfaces contact area are bigger,
The heating of safety can be achieved under the cooperation of Safety Extra Low Voltage DC power supply simultaneously, the thickness of insulating layer 8 may be selected non-at this time
Often thin coating improves heating efficiency, forms immediate heating type seat ring.
The present embodiment preferably the heating film 7 temperature-coefficient of electrical resistance be greater than+2 ‰, with the temperature liter of heating film 7
Height, resistance increase with it, excessively high to prevent stopping seat circle surface temperature, limit high temperature to play the role of safeguard protection.
Insulating layer 8 described in the present embodiment includes the paint for being sprayed at heating layer surface or the thermoplasticity material of injection molding
Material, wherein thermoplastic material can be PP, ABS etc., preferably solidify resin of the hardness greater than 2H and paint, the insulating layer 8
Thickness is less than 0.5mm, first in production, can be painted on cured 7 surface of heating film, high production efficiency, next is compared
Thickness substantially reduces for thermoplastic material, and heat conduction efficiency is high, and fever is fast, while its hardness is sufficiently large, avoids scratching, excellent
The insulating layer 8 of choosing is with a thickness of 0.2mm.
The present embodiment further includes control chip, control circuit and signal deteching circuit, and control chip is according to signal detection electricity
The signal feedback on road carries out operation, and operation result determines the heating power of the heating film 7, determines that user is by control circuit
It is no to take a seat, if having taken a seat, so that heating film 7 is carried out power output heating by controlling chip, otherwise disconnect the power of heating film 7
Output.
As Figure 7-9, a kind of signal acquisition method of taking a seat of constant temperature seat ring includes capacitance detecting electricity in control circuit
Road, signal of taking a seat are determined by capacitive detection circuit；When detecting capacitance signal, electronic switch is disconnected in capacitive detection circuit, user
When not taking a seat, detects and detect fixed equivalent capacity C1 between port and signal ground；When user takes a seat, in detection port and letter
An additional equivalent capacity C2 in parallel with C1 is formed between number ground, the setting capacitance change, Δ C threshold value in control chip program,
Whether reach given threshold by comparing the capacitance change, Δ C on detection port, determines that user has taken a seat when more than threshold value.
Detailed process is, when seat ring does not heat, the electronic switch K1 in capacitive detection circuit is disconnected, and detects port C_
SAMPLE is in suspended state；If user is not landed on seat ring at this time, between port C_SAMPLE and signal ground
It can detect a relatively-stationary equivalent capacity C1 (Fig. 8)；If user is sitting on seat ring at this time, since the capacitor of human body is made
With being equivalent between port C_SAMPLE and signal ground an equivalent capacity C2 (Fig. 9) again in parallel, total equivalent capacity becomes
For C1+C2；Therefore it is disconnected in K1, when seat ring does not heat, detects capacitance change, Δ C=(C1+C2)-C1=C2 on port, than
Whether reach threshold value compared with Δ C, can learn whether user is in the state taken a seat, can be saved in the way of this in the prior art
Take a seat inductor, reduce it is whole occupy volume, reduce production cost, become thinner seat ring.
As shown in fig. 7, a kind of temprature control method of constant temperature seat ring, obtains the surface of seat ring by signal deteching circuit
Real-time temperature T reduces heating power when temperature T is greater than target temperature Tt, when temperature T is less than target temperature Tt, increases hair
Thermal power, the real-time temperature T=(R-R0)/(R0*TCR)+T0, wherein R is the instant resistance of heating film 7, and T0 is benchmark temperature
Degree, R0 are the resistance values of heating film 7 under fiducial temperature, and TCR is the temperature-coefficient of electrical resistance of heating film 7.
All conductive materials have a relatively-stationary temperature resistance coefficient TCR, are indicating the every raising of temperature once, electricity
Resistance change on the original basis how much.TCR is basically unchanged within the scope of certain temperature, and has higher precision and stabilization
Property.
There is physical equation: TCR* Δ T=Δ R/R0；
Wherein Δ T=T-T0, Δ R=R-R0；
It can obtain: TCR* (T-T0)=(R-R0)/R0；
Then T=(R-R0)/(R0*TCR)+T0；
The measurement and calculating of R and R0: by capacitive detection circuit Fig. 7 it is found that in electrified regulation, have
U/Vcc=Rbase/(Rbase+ R) be easy to get R=Vcc*Rbase/U-Rbase；
U0/ Vcc=Rbase/(Rbase+R0) be easy to get R0=Vcc*Rbase/U0-Rbase；
Wherein, RbaseFor the reference resistance of temperature drift very little, it is far from heating seat ring, and resistance value is not substantially by temperature shadow
It rings；U is R when being heated to temperature TbaseOn sampled voltage；U0To be heated to temperature T0When, RbaseOn sampled voltage；Vcc is
Supply voltage value.
