Description

Technical Field

[0001] This utility model relates to the field of toilet tank technology, and in particular to a scale-resistant toilet tank. Background Technology

[0002] In modern homes, the toilet is an indispensable sanitary facility, and the performance of its tank directly affects the user experience and the toilet's lifespan. With the increasing prominence of water quality issues, limescale buildup in toilet tanks has become a problem plaguing many users. Limescale forms from calcium and magnesium ions in the water. Under conditions such as water temperature changes and water evaporation, these ions gradually crystallize and adhere to the inner wall of the tank, the inlet valve, the drain valve, and the surfaces of various pipes.

[0003] A scale-resistant toilet tank disclosed in publication number CN210177621U includes a tank shell, a cleaning solution bottle, and a transmission mechanism. The tank shell has a movable cover at its top, with the cleaning solution bottle located at the top of the movable cover. The transmission mechanism inside the tank shell includes a transmission wheel, an adjusting slider, a first lead screw, a motor, a second lead screw, a belt, and a guide wheel. A rectangular fixing plate and cleaning bristles are fixed to the outer side of the adjusting slider. T-shaped sliders are located at the middle of both ends of the rectangular fixing plate. An outlet and an inlet are respectively located on both sides of the bottom of the tank shell. A sink is bolted to one side of the tank shell. Second fixing mechanisms are fixed to the top of both sides of the tank shell, and a first fixing mechanism is slidably mounted below each of the second fixing mechanisms via a T-shaped groove. This invention facilitates scale removal, reduces water waste, and is easy to disassemble and install.

[0004] While the aforementioned patent facilitates the cleaning of limescale, reduces water waste, and is easy to disassemble and install, the device lacks a detachable filter structure at the inlet and outlet. Impurities in the water can clog the pipes due to the lack of a filter structure, affecting the normal use of the equipment. Utility Model Content

[0018] (III) Beneficial Effects

[0019] This utility model provides a scale-resistant toilet tank, which has the following beneficial effects:

[0020] 1. This anti-scaling toilet tank, through the design of a backwashing mechanism and an ultrasonic mechanism, allows for efficient cleaning during use. By turning the three-way valve on the three-way pipe, a passage is created between the drain pipe and the backwashing pipe. Water then flows through the backwashing pipe into three atomizing nozzles on the top wall of the tank body. These nozzles flush away the dirt adhering to the inner wall of the tank, and the flushed wastewater is discharged from the drain port at the bottom. Furthermore, the ultrasonic transducer and ultrasonic generator work together to generate high-frequency vibrations in the water, breaking down the adhesion between the scale and the inner wall of the tank, causing stubborn scale to loosen and fall off.

No manual operation is required; the structure is simple, convenient, and practical.

[0021] 2. This scale-resistant toilet tank features a filtration system with two removable filter screens at both the inlet and outlet. These screens filter impurities from the water source, and the flow meter monitors the flow rate in real time. If the water flow is too low, an alarm light is activated to promptly remind staff to replace and clean the filter screens. This ensures the purity of the water source and prevents excessive impurities from clogging pipes and internal parts, thus ensuring the normal operation of the equipment. Attached Figure Description

With the filter mechanism 6, the purity of the water source is ensured, and the excessive impurities in the water source are prevented from clogging the pipes and internal parts, thus affecting the normal use of the equipment.

[0029] The backwashing mechanism 2 includes a flow pipe 201 installed at the top of the water tank body 1, three atomizing nozzles 202 installed at the bottom of the flow pipe 201, and a backwashing pipe 203 connected to the top of the flow pipe 201 through a hose.

[0030] The ultrasonic mechanism 3 includes an ultrasonic generator 301 installed on one side of the water tank body 1, and an ultrasonic transducer 302 is electrically connected to one side of the ultrasonic generator 301 via a power line.

[0031] The filter mechanism 6 includes a flange connector 601 threaded to one side of the inlet 4 and the outlet 5. A filter pipe 602 is installed on one side of the flange connector 601, and two filter screens 603 are installed inside the filter pipe 602.

[0032] A drain pipe 7 is connected through one side of the outlet 5, and a tee pipe 8 is connected through one side of the drain pipe 7. The drain pipe 7 serves to drain water.

[0033] A three-way valve 9 is installed on the surface of the three-way pipe 8. The top of the three-way pipe 8 is connected to the inside of the backwash pipe 203. The three-way valve 9 changes the direction of water flow.

[0034] A flow meter 10 is installed on one end of the surface of both the inlet 4 and the outlet 5. A PLC controller 11 is electrically connected to one side of the flow meter 10 via a power cord.
