Example 1

The system is applied to sanitary ware with a water tank for defecation, such as a toilet bowl, a squatting pan and the like.

Referring to fig. 1, the vacant position of the water tank can be used for installing a disinfecting liquid feeding system of toilet sanitary equipment based on venturi effect, including a water inlet valve 1, without affecting the height adjustment and backflow prevention function of the original water inlet valve, a flow control valve 110 is added on the water seal water replenishing outlet at the upper part of the water inlet valve 1, at the bottom of the water inlet valve 1, a water outlet port is connected at the water outlet of the water inlet valve 1, water flow is converged into a Venturi tube to provide water flow, the modes of connecting the water outlet port of the water inlet valve 1 with the water outlet port are various, if gluing, hot melt, clamp, cup joint, integrated into one piece etc. what this embodiment adopted is cup jointed an angle adjustable quick socket joint tee 101, with hose 2, with the tee bend interface 111 of water intaking valve 1 and the entry inlet end 301 of venturi 3 be connected, form the water inlet channel, this passageway is located the bottom in the water tank, does not influence original drainage system. The venturi tube 3 is fixedly connected with the liquid storage device 5, namely the venturi tube throat introducing pipe 303 is fixedly connected with the liquid storage device 5, and the connecting mode comprises adhesive connection, hot melting, clamping hoop, threaded connection and integrated forming. In this embodiment, a hot-melt connection mode is adopted to fixedly connect the venturi throat introduction pipe 303 with a liquid outlet 510 at the bottom of the liquid storage device 5, the liquid outlet 510 at the bottom of the liquid storage device 5 and the venturi throat introduction pipe 303 form a drainage channel, the bottom of the throat introduction pipe 303 is in a step hole shape, a spring 312 and a check valve core 313 are installed on a step, and a suction and liquid backflow prevention valve is formed by the step and a rubber gasket 314 with a port; liquid outlet 510 through-hole size of stock solution device 5 is controlled by flow control dress subassembly, adjusting link 511 including conical head, auto-lock adjust knob 513, the regulation scale dial plate 512 at 5 tops of stock solution device, there is the through-hole scale dial plate center, adjust knob 513 and adjusting link 511 fixed connection, through adjust knob 513, the size of control liquid outlet 510 through-hole, the realization is adjusted inspiratory disinfectant dose, it is stable adjustable to reach antiseptic solution concentration, in order to realize practicing thrift the purpose of antiseptic solution. The water outlet end 302 of the venturi tube 3 is connected with an impeller 431 and a pore plate 432, the impeller 431 rotates to fully mix the water flow mixed with the disinfectant, and the pore plate 432 reduces the noise of the water flow.

When flushing, water flows into the water inlet valve 1 and enters the water inlet channel 2 through the three-way connector 111, the water flows in the Venturi tube 3, the dynamic pressure reaches the maximum value at the narrowest part of the pipeline, the static pressure reaches the minimum value, and the speed of the water flow rises due to the reduction of the area of the cross section of the through flow. The entire flow is subjected to the pipe reduction process at the same time, and the pressure is reduced at the same time. And then the pressure difference is generated, the pressure difference provides an external suction force for the water flow, the spring 312 contracts under the action of the external suction force, the check valve core 313 moves downwards, the drainage channel is communicated, the disinfectant in the liquid storage space in the shell of the liquid storage device 5 is introduced into the Venturi tube through the liquid outlet of the liquid storage device to be mixed, and flows into the water tank for storage after being mixed and silenced through the water outlet channel, and when the button is flushed, the water mixed with the disinfectant is flushed out, so that the disinfection of the toilet bowl and the squatting pan is realized. A liquid storage device 5 of the system is fixedly arranged in the water tank and can be fixedly connected with an overflow pipe 6 and the wall of the water tank. Stock solution device 5 and 6 fixed connection of overflow pipe in this embodiment, 5 casing sides of stock solution device set up the arc mounting groove, with T shape screw 541 buckle in 5 fixed slots of stock solution device to on pipeline clamp 540 is fixed in the overflow pipe upper and lower position, use after the fixed completion of screw 540 locking.

The device can be debugged once and used in the follow-up process, and the input amount of the disinfectant can be ensured by each flushing action, so that the sterilization and disinfection effects can be achieved. Meanwhile, the liquid storage device can store a large amount of disinfectant, so that the labor input is low, and the liquid storage device is particularly suitable for places with dense pedestrian flow.

Example 2 the system is applied to toilet utensils such as urinals and the like which do not use a water tank.

The inlet end 301 of the venturi tube 3 is connected with the water outlet of the urinal water inlet valve, water flows into the venturi tube 3, under the action of the venturi effect, the check valve core 313 of the venturi tube 3 is adsorbed and moves downwards, the drainage channel is communicated, and disinfectant stored in the liquid storage device 5 enters the venturi tube 3 through the liquid outlet 510 and flows out through the outlet end 302 to flush the urinal. Flow regulating assembly on the liquid storage device 5: the flow scale dial 512, the adjusting connecting rod 511 and the self-locking adjusting knob 513 realize the adjustment of the flow of the disinfectant, and finally realize the functions of adjusting, quantifying and automatically putting in the disinfectant.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof should be equally replaced or changed within the technical scope of the present invention.
