Description

Technical Field

[0001] This utility model relates to the field of mop sink technology, and in particular to a mop sink with a novel drainage mechanism. Background Technology

[0002] A mop sink is a hygiene appliance primarily used for cleaning mops. Mop sinks are typically made of ceramic and have a drain at the bottom to facilitate the removal of wastewater generated during mop washing.

[0003] With technological advancements, mop sinks have become increasingly sophisticated. For example, the authorized Chinese patent "201921379340.4," titled "A Novel Mop Sink," describes a design where "during use, the diameter of the outlet pipe can be altered by adjusting the distance between two clamping blocks on the outside of the water pipe, slowing the downward flow of water within the mop sink. Simultaneously, the middle section of the corrugated pipe can be placed on a block on one side of the upper plate. The block's arc-shaped surface allows the middle section of the corrugated pipe to form a U-shape, reducing the speed of the water flow directly into the outlet and ensuring normal flow of wastewater within the mop sink. This improves the mop sink's practicality. When cleaning the mop, workers can use the protrusions on the surface of the protrusion plate to rub and squeeze the mop, quickly removing debris and increasing cleaning efficiency to some extent." As can be seen, while the aforementioned patent achieves its stated objectives, it also suffers from the following technical shortcomings, similar to other mop sinks in the field, due to structural and functional limitations. Specifically, the drain valve of the mop sink relies on the user to manually open or close it, which is inconvenient and does not provide a good user experience. Therefore, it is essential to provide a mop sink with a non-contact control for opening and closing the drain valve. Utility Model Content

[0004] To overcome the shortcomings of existing mop sinks due to structural limitations, as described in the background art, this utility model provides a mop sink body that, under the combined action of related mechanisms and circuits, can use the water used to rinse the mop as power to supply the entire device, saving energy and reducing the inconvenience of charging. It can open or close the water valve in a non-contact manner, thereby bringing convenience to users and improving the product's market competitiveness.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A mop sink with a novel drainage mechanism includes a mop sink body, a storage battery, a photoelectric switch, a solenoid valve, a water flow generator, and a trigger circuit and a control circuit. A drain pipe is fixedly installed at the drain outlet of the mop sink body, and a filter plate is fixedly installed at the upper end of the drain pipe. The inlet pipe of the solenoid valve is fixedly connected to the lower end of the drain pipe, and the inlet pipe of the water flow generator is fixedly connected to the outlet pipe of the solenoid valve. The storage battery, photoelectric switch, trigger circuit, and control circuit are installed inside a component box. The probe of the photoelectric switch is located outside the opening at the front of the component box, and the component box is fixedly installed on the front outer side of the mop sink body. The power output terminal of the generator is electrically connected to the two poles of the storage battery, and the power input terminals of the trigger circuit, control circuit, and photoelectric switch, respectively. The signal output terminal of the photoelectric switch is electrically connected to the signal input terminal of the trigger circuit, the signal output terminal of the trigger circuit is electrically connected to the signal input terminal of the control circuit, and the power output terminal of the control circuit is electrically connected to the power input terminal of the solenoid valve.

[0007] Furthermore, the upper end of the drain pipe has a limiting ring, and the outer side of the filter plate is fitted onto the inner end of the limiting ring, with the height of the filter plate being the same as the height of the limiting ring.

[0008] Furthermore, the solenoid valve is a normally open solenoid valve with a spool.

[0009] Furthermore, the upper end of the filter plate is lower than the lower end of the mop pool, and the surface of the filter plate is covered with multiple filter holes.

[0010] Furthermore, the trigger circuit includes an electrically connected resistor and a dual-D trigger module. One end of the resistor is connected to the signal input terminal 3 of the dual-D trigger module, the data input terminal 5 and the inverted code output terminal 2 of the dual-D trigger module are connected, and the negative power input terminal 7, the direct reset terminal 4, and the direct set terminal 6 of the dual-D trigger module are connected.

[0011] Furthermore, the control circuit includes an electrically connected resistor, a transistor, and a relay. The positive power input terminal of the relay is connected to the input terminal of the control circuit, the collector of the transistor is connected to the negative power input terminal of the relay, and one end of the resistor is connected to the base of the transistor.

[0012] Compared with existing technologies, the advantages of this invention are as follows: Based on the mop sink body, this invention has functions such as cleaning mops. Specifically, this invention does not require manual operation of the valve by the user. When the user's foot or other body approaches the photoelectric switch probe, the photoelectric switch outputs a high-level signal, which enters the trigger circuit. The trigger circuit and control circuit then control the water valve to open or close. Furthermore, since it uses the water flowing from the mop sink to generate electricity, no external power supply is required, bringing convenience to the user and improving the product's market competitiveness. In summary, this invention has good application prospects. Attached Figure Description

[0017] Figure 1 , 2 As shown in Figures 1 and 3, a mop sink with a novel drainage mechanism includes a mop sink body 1, a storage battery G1, a photoelectric switch W1, a solenoid valve DC, a small water flow generator FD, and also has a trigger circuit 2 and a control circuit 3. A drain pipe 101 is fixedly installed at the drain outlet of the mop sink body, and a filter plate 102 is fixedly installed at the upper end of the drain pipe 101. The inlet pipe of the solenoid valve DC is fixedly connected to the lower end of the drain pipe 101, and the inlet pipe of the water flow generator FD is fixedly connected to the outlet pipe of the solenoid valve DC. The storage battery G1, photoelectric switch W1, trigger circuit 2, and control circuit 3 are installed on the circuit board inside the component box 4. The probe of the photoelectric switch W1 is located outside the opening in the front middle of the component box 4. The rear end of the waterproof component box 4 is fixedly installed on the mop sink body. Outside the front end of the battery body 1, the generator FD power output terminal and the two poles of the battery G1, the power input terminal of the dual-D trigger module W2 of the trigger circuit (pins 14 and 7), the power input terminal of the relay J1 of the control circuit (positive power input terminal and the emitter of the transistor T1), and the power input terminals 1 and 2 of the photoelectric switch W1 are connected by wires. The signal output terminal 3 of the photoelectric switch W1 and the signal input terminal of the dual-D trigger module W2 of the trigger circuit (pin 3) are connected by wires. The signal output terminal of the dual-D trigger module W2 of the trigger circuit (pin 1) and the signal input terminal of the resistor R1 of the control circuit (the other end of the resistor R1) are connected by wires. The normally open contact terminal of the relay J1 of the control circuit (normally open contact), the emitter of the transistor T1, and the power input terminals of the solenoid valve DC are connected by wires.

[0018] Figure 1 , 2As shown in Figure 3, the upper end of the drain pipe 101 has a limiting ring 1011, and the outer sealing sleeve of the filter plate 102 is inside the limiting ring 1011. The height of the filter plate 102 is the same as the height of the limiting ring 1011. The solenoid valve DC is a normally open valve core solenoid valve. The upper end of the filter plate 102 is lower than the lower end of the mop pool body 1, and multiple filter holes 1021 are distributed on the surface of the filter plate 102. The trigger circuit includes a resistor R and a dual-D trigger module W2 connected by circuit board wiring. One end of the resistor R is connected to the signal input terminal 3 of the dual-D trigger module W2. The data input terminal 5 and the inverted code output terminal 2 of the dual-D trigger module W2 are connected. The negative power input terminal 7 of the dual-D trigger module W2 is connected to the direct reset terminal 4 and the direct set terminal 6. The control circuit includes a resistor R1, a transistor T1, and a relay J1 connected via circuit board wiring. The positive power input terminal of the relay J1 is connected to the input terminal of the control circuit. The collector of the transistor T1 is connected to the negative power input terminal of the relay J1. One end of the resistor R1 is connected to the base of the transistor T1.

[0019] Figure 1 , 2As shown in Figure 3, this new invention, based on the mop sink body 1, has functions such as cleaning mops (closing the solenoid valve DC, filling the mop sink body 1 with water, cleaning the mop, and then opening the solenoid valve DC to release the cleaned water). Because it has a filter plate 102, it can filter out impurities generated after cleaning the mop, preventing excessive impurities from entering the volute of the water flow generator FD and causing malfunctions. In this invention, each time the water in the mop sink body 1 is discharged, the water flow impacts the impeller of the water flow generator FD. The impeller drives the rotor of the water flow generator to rotate, thus the water flow generator FD outputs a DC power of 12V or higher to charge the battery G1, which in turn powers the entire circuit via the battery G1 (pre-charged before leaving the factory). Since no power supply line is needed to power the equipment, energy is saved. After the power output from the battery G1 enters the power input terminals of the trigger circuit, control circuit, and photoelectric switch W1, the trigger circuit, control circuit, and photoelectric switch W1 are energized and operate. When the user needs to fill the mop sink body 1 with water, they should place their foot or mop within 8 centimeters of the probe head of the photoelectric switch W1. This will cause pin 3 of the photoelectric switch W1 to output a high level, which will enter pin 3 of the dual-D trigger module W2. As a result, the bistable circuit in the dual-D trigger module W2 will flip once, and pin 1 of the dual-D trigger module W2 will output a high level, which will be reduced and current limited by resistor R1 and enter the base of transistor T1. Transistor T1 will conduct, and the collector will output a low level, which will enter the negative power input terminal of relay J1. Relay J1 will be energized and its control power input terminal and normally open contact terminal will close. This will energize the DC solenoid valve and close the valve core. After the user turns on the faucet on the wall above the mop sink body 1, tap water will enter the mop sink body 1 to fill it with water. After the water volume is sufficient, the user will turn off the faucet and then wash the mop in the mop sink body 1. When the user needs to drain the water from the mop sink body 1, they should bring their feet or other objects within 8 centimeters of the probe of the photoelectric switch W1. This will cause pin 3 of the photoelectric switch W1 to output a high level again, which will then enter pin 3 of the dual-D trigger module W2. Consequently, the bistable circuit within the dual-D trigger module W2 will flip again (the next time pin 3 of the dual-D trigger module W2 inputs a high level, pin 1 will output a high level again, energizing the solenoid valve DC and closing its valve core). Pin 1 of the dual-D trigger module W2 will stop outputting a high level into the base of transistor T1. Transistor T1 will then be cut off, and its collector will no longer output a low level into the negative power input terminal of relay J1. Relay J1 will be de-energized and will no longer engage, opening its control power input terminal and normally open contact terminal. This will cause the solenoid valve DC to de-energize and open its valve core, allowing the water in the mop sink body 1 to be discharged downwards via the water flow generator and solenoid valve D. During the water flow process, the water flow generator generates electrical energy to charge the battery G1.As described above, this new type of device eliminates the need for manual valve operation by the user. When the user's foot or other body approaches the photoelectric switch probe, the photoelectric switch outputs a high-level signal that enters the trigger circuit. The trigger circuit and control circuit then control the generator to open or close the solenoid valve. Furthermore, since the device generates electricity using water flowing from the mop pool, it does not require an external power supply, which brings convenience to the user and enhances the product's market competitiveness. Figure 3 In this setup, the FD water-flow generator is a 12V small water-flow DC generator; the J1 relay is a DC12V relay; the T1 transistor is a 9013 (NPN type); the resistors R and R1 have resistances of 100Ω and 4.7K respectively; the DC solenoid valve is a 2W normally open solenoid valve; the G1 battery is a 12V / 5Ah lithium battery; the W2 dual-D trigger module is a CD4013; and the W1 photoelectric switch is an E3F-DS30C4 infrared sensor photoelectric switch with two power input terminals and one signal output terminal. When there is an obstacle in front of the detector, the signal output terminal outputs power; when there is no obstacle in front of the detector, the signal output terminal does not output power. The detection distance is 30 cm. The rear of the photoelectric switch housing has a distance adjustment knob. Adjusting it to the left shortens the detection distance, and adjusting it to the right lengthens the detection distance (in this embodiment, it is adjusted to about 6 cm).
