Description
Technical field
The utility model belongs to a kind of technical field of sanitaryware accessory, is specifically related to a kind of tank for excrement pan draining valve that can respond to control or manually control.
Background technology
Traditional water tank drain valve is generally to adopt manual control mode, be provided with button, and draining valve is provided with startup button on water tank surface, and water tank button is positioned at above the startup button of draining valve.When pressing lower header button, the startup button of draining valve declines thereupon, so fork swings and make lifting arm and sealing piece increase, draining valve is opened; When unclamping water tank button, the startup button of draining valve upwards resets under the power effect of the upwards top of back-moving spring, and draining valve just cuts out.
Because manual control mode needs manual operation, seem inconvenient, more there is sub-fraction people to forget or the bath that do not push button because fearness is dirty, therefore, people have designed induction type water tank drain valve, it utilize human inductor perception whether have user near or leave, and by microprocessor control electromagnetic mechanism (motor drive mechanism) action, and then control opening or closing of draining valve by electromagnetic mechanism (motor drive mechanism).
But still there is following problem in simple induction type water tank drain valve: in the time having a power failure or electromagnetic mechanism electronic component damages, draining valve just can not use.For this reason, people have designed again the tank for excrement pan draining valve that can select to adopt induction control mode or manual control mode, are called for short inductive and manual dual-purpose water tank drain valve.
But there is following problem in existing inductive and manual dual-purpose water tank drain valve: because back-moving spring applies upwards thrust to starting button, the elastic force that electric control mechanism must overcome back-moving spring could drive fork to swing, and draining valve volume is little, the motor volume that can install is also less, be that motor thrust is little, therefore motor is difficult to overcome spring thrust, for above-mentioned reasons, the electric-powered mode of existing inductive and manual dual-purpose water tank drain valve mainly contains following two kinds of modes: one, by means of the pressure of tap water, whether utilize the transmission of electromagnetic valve open and close controlling tap water hydraulic, the disclosed structure of Chinese utility model patent that for example notification number is CN201056754, two, utilize motor-driven gear to rotate, the motion of gear driven stay cord, stay cord directly drags lifting arm and sealing piece rises, so avoid the resistance of back-moving spring, the disclosed structure of Chinese utility model patent that for example notification number is CN200967988.But it is complicated that above-mentioned two structures all seem, and draining valve is seemed, and volume is too fat to move.
Utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of inductive and manual dual-purpose water tank drain valve is provided, and its structure is ingenious, and volume is small and exquisite.
Its object can realize by following scheme: a kind of inductive and manual dual-purpose water tank drain valve, comprise cylindrical shell, and cylindrical shell bottom is provided with outfall; Cylindrical shell top is provided with push-button socket, and push-button socket is provided with and starts button and back-moving spring, and starting button can vertically be arranged in push-button socket actively, and back-moving spring applies upwards thrust to starting button; Start button lower end and be fixedly connected with the first briquetting; Fork is installed in cylindrical shell, and the balance staff of fork is horizontal direction, and the first briquetting is positioned at the first end top of fork; The second end of fork is lifted with drive link, and the lower end of drive link is connected with lifting arm, and the lower end of lifting arm is connected with sealing piece, and sealing piece activity is covered on the outfall top of cylindrical shell bottom; It is characterized in that, cylindrical shell top is also provided with fixed bearing, motor is installed in fixed bearing, the vertical rotating shaft of motor is coaxially connected with vertical screw rod, vertical screw rod outside is arranged with nut, nut is circumferentially fixed and is arranged on axially and movably on fixed bearing, and nut lower end is fixedly connected with the second briquetting, and the second briquetting is also positioned at the first end top of fork.
Also be provided with human inductor and microprocessor, human inductor connects microprocessor, and microprocessor connects described motor.
The utlity model has following advantage and effect:
One, automatic inductive mode of the present utility model directly drives the first end of fork to move downward by nut, and utilize leverage to drive drive link, lifting arm, sealing piece moves up, and fork motion process does not need to overcome the resistance of back-moving spring, therefore the resistance that motor need to overcome is very little, mean that motor can design very littlely, add that vertical screw rod is coaxially connected with the rotating shaft of motor, nut sleeve is in vertical screw rod periphery, therefore the volume of whole motor-driven mechanism can do very littlely, in practice, the diameter of whole system can only have two centimeters of left and right, structure is ingenious, volume is small and exquisite.
