First, Burdick lamp inevitably uses power supply, and in order to protect it to scrub environment for the special of toilet, power unit of the present invention is all designed to be placed in the cavity of watertight.Described cavity includes ultraviolet (uv) transmission window, induction apparatus window and power supply and control line outlet.And artificial on and off switch of the present invention and irradiation duration selector switch are designed to be placed near far end supply plug.Also can add an earth leakage protective device simultaneously, endanger without electric leakage when guaranteeing general cleaning.
Secondly, the cavity of above-mentioned watertight of the present invention can be placed in the bottom of ring, the upper cover plate of such toilet can be simplified, and by optimizing disinfection by ultraviolet light lamp body for the height of ring plane and the angle that has a down dip, can irradiate ring and inner most of region, but the irradiating angle of Burdick lamp is still by restriction to a certain extent simultaneously.
In order to Burdick lamp is farthest irradiated to ring and the inside of toilet, the cavity of above-mentioned watertight also can be placed in the middle part of the upper cover plate of toilet.For this mode, the bottom side of disinfection by ultraviolet light lamp body of the present invention comprises a transverse axis that can freely rotate, the below of lamp body comprises an angular definitions vernier, described rotation transverse axis and vernier make the irradiating angle of light adjust to some extent when cover plate starts and put down: when toilet upper cover plate is erect, lamp body has a down dip to irradiate whole ring by gravity comprehensively, and when toilet upper cover plate puts down in level, hang down in lamp body inner with cover.
In order to improve the Mechanical Reliability that Burdick lamp upper cover plate is settled, reduce shock when falling, components and parts are put in protection.The connection of rotating axle of upper cover plate and lower ring can adopt gas, liquid, or the technology such as reed makes it have damping characteristic.Simply, can the rotary damper of choice for use corresponding size and coefficient, one-way buffer (falling direction).
Moreover, ultraviolet has the effect of killing antibacterial, but also there is certain injury to human body skin, so an important design of the present invention is induction automatically and controls automatically to disconnect ultraviolet radiation when human body proximity, automatic unlatching ultraviolet radiation after human body leaves, and automatically disconnect after the time of irradiating setting.
In order to realize such automatic control function, the present invention is except said structure part, also comprise the DC power supply unit of an ac-dc conversion or rechargeable battery, a power supply automatic control switch, this power supply automatic control switch and ultraviolet lamp body and power supply hand switch loop in series, a human body proximity sensor circuit unit, a level sensor circuit unit, a timing circuit unit, and one is responded to the control circuit unit controlling ultraviolet radiation automatically.The concrete formation of these described unit and relation as follows:
1. the DC power supply unit of the ac-dc conversion described in, independent of Burdick lamp on and off switch, namely cuts off the direct current supply that Burdick lamp on and off switch does not affect ac-dc conversion, thus makes induction and control circuit remain duty after power.On the other hand, if market special requirement does not operationally have external power supply, by the connection of corresponding power pack, also can according to the characteristic of commutator use rechargeable battery as power supply directly or after alternating current-direct current inversion for Burdick lamp is powered.
2. the human body proximity sensor circuit unit described in human body proximity sensor circuit unit described in comprise one or combination multiple employings infrared, or it is ultrasonic, or the target range sensing device group of the technology such as microwave and signal amplification shaping circuit, this human body proximity sensor circuit unit is connected with timing circuit unit and control circuit unit, transmits with or without human body high or low level controling signal " people leaves " on the scene or " people is close ".
3. the level sensor circuit unit described in is characterized in that described level sensor circuit unit comprises one and adopts hydrargyrum, or conducting sphere, or the level sensing device of the embodiment action of gravity of the technology such as active conductive hinge and signal amplification shaping circuit, this level sensor circuit unit is connected with timing circuit unit and control circuit unit, part is connected with human body proximity sensor circuit unit simultaneously, and transmission water-closet bowl cover plate or ring are high or low level controling signal " level " or " upright state " that level still starts upright state.Or for the enforcement demand simplified, described level sensor circuit unit can be that induction integrally directly carries out the cut-out in Burdick lamp loop with closed with on and off switch.
4. the timing circuit unit described in comprises an agitator and frequency dividing circuit clock signal, Hour Minute Second counting is carried out with an enumerator combination, bootloader count status and outputs level signals " timing zero ", after enumerator is enable, have 30 points and 60 minutes or more timing length select export, through time length selector switch export wait for specific level signal " timing is full ".For simplifying enforcement completely, namely product determines that degradation cancels timing function, timing circuit unit can be deteriorated to a ground signalling or sky completely, at this moment described agitator can be omitted, frequency dividing circuit, enumerator combines, and timing length selector, and corresponding counter O reset signal extracting circuit sum counter is enable or remove enable control circuit.Obviously such simplification is implemented owing to not having timing controlled can compare expense electricity.
5. the inductive control circuit unit described in comprises an ON-OFF control circuit module and a counter O reset signal extracting circuit module and signal adaptation circuit module.Described inductive control circuit unit controls according to described human body proximity induced signal and level status signal the irradiation disconnecting or directly disconnect described Burdick lamp after the closed described timing circuit sets duration of described power supply automatic control switch, and this control circuit carries out resets clearing and enable or go enable and by " timing is full " signal latch according to described human body proximity induced signal and level status signal to timing circuit simultaneously.
6. without loss of generality, if it is " people leaves " signal that human body proximity sensor circuit unit exports high level, if it is " level " signal that level sensor circuit unit exports high level, described counter O reset signal extracting circuit module comprises two d type flip flops or the cascade of similar d type flip flop functional module, the output of first order d type flip flop and the output of second level d type flip flop are through one " XOR gate ", it exports with the output of one-level d type flip flop again through one " with door ", to extract the change time point of human body close signal and level status signal, supposing that low level resets resets then again through the conversion of one " not gate " adaptation, and then counter unit is carried out to the clearing reset of state and output.
7. without loss of generality, if it is " timing is full " signal that timing circuit timing exports high level, if ON-OFF control circuit module exports " switch closes " signal that high level is ultraviolet power supply automatic control switch.Because level induced signal is placed in the upper cover plate of toilet middle part at Burdick lamp is different from the demand for control of the bottom being placed in ring, described ON-OFF control circuit two kinds of situations below of dividing (suppose that " people leaves " is for high level signal CLR, " level " is high level signal HRZ, " timing is full " is high level signal TMR, and gauge tap " closes " as high level signal CTL):
A. when Burdick lamp is upper cover plate arrangement, being exported by the output of human body proximity sensor circuit unit and level sensor circuit unit first carries out after "or", export the signal after " not gate " again with timing circuit timing and carry out "AND", export to ultraviolet power supply automatic control switch and control: CTL=(CLR+HRZ) (-TMR)
B. when the bottom being ring at Burdick lamp is settled, exported by timing circuit timing and to export and level sensor circuit unit exports and carries out "AND" through one " not gate " and human body proximity sensor circuit unit, export to ultraviolet power supply automatic control switch and control: CTL=(-TMR) CLRHRZ
8. owing to there is the selection of different concrete components and parts models, for input, export, clock, resets, and resets, signal such as enable and controls grade, may need or not need the conversion through utilizing the adapter circuit of " not gate " or simple shaping circuit to carry out signal level, preferably the Uniting when parts selection, avoids unnecessary conversion as far as possible.But note, human body sensing exports and controls adapter circuit when upper cover plate is settled and settled in ring bottom, control for " triple gate " of human body sensing output is contrary, one makes human body sensing output invalid in " level ", and another kind makes human body sensing output invalid in " upright state ".
9., because most of ultraviolet is invisible, as additional function, can increase by a power supply conducting display lamp in Burdick lamp loop, to express the duty of Burdick lamp.
10. these above-mentioned circuit units can use discrete device to form, and customization or semi-custom integrated device also can be used to comprise the formations such as programming device.
Thus, according to the present invention, this UV disinfected toilet can carry out the sterilizing setting duration after each people use end to leave, once there be human body proximity, automatically closes and irradiates to protect human body to escape injury.Meanwhile, according to the present invention, it is energy-conservation that this UV disinfected toilet has multinomial additional function, waterproof, damping, and maximize germicidal irradiation angle.
