Description

Technical Field

[0001] This invention relates to the field of low-voltage switchgear technology, and more specifically to a low-voltage switch. Background Technology

[0002] A low-pressure switch is a device used in water purifier pipelines to detect water pressure levels and control the purifier's operation to protect it. Its main components include a top cover with a dual-line interface on the top, a raised button on the bottom, a T-shaped bottom tube connected to the bottom, a sealing ring inside the bottom tube, a round sleeve on top of the sealing ring, a top plate on top of the round sleeve, a top rod at the bottom of the T-shaped bottom tube, and a small disc at the head of the top rod. It is widely used in reverse osmosis water purifiers.

[0003] When using the existing low-pressure switch, the water purifier's connecting pipe is first connected to the water source pipe to provide a water supply. When the low-pressure switch detects the water pressure, the water pressure in the pipeline will reach the corresponding pressure, which will lift the small disc and drive the push rod to lift the large disc on the T-shaped top. When the large disc touches the top pressure protrusion, the electrical signal is transmitted to the water pump through the wiring harness connected to the top, ensuring that there is sufficient water in the pipeline for operation. When the water pressure is too low, a signal will be transmitted to stop the water pump and the machine to prevent the machine and water pump from running dry and causing losses.

[0004] The existing low-pressure switch, during use, if the water pressure at the water inlet is too low, even if there is water flowing in the pipeline, when it reaches the low-pressure switch for detection, the water pressure cannot push up the small disc, causing the machine's water pump to fail to work. This results in the water flowing continuously inside the machine, damaging the machine and affecting its service life. If too much dirt accumulates at the water source, causing dirt to mix into the pipeline and affecting the water pressure, the disc cannot be pushed up. The error signal of low water pressure or no water flow in the pipeline is transmitted to the water pump, causing the water pump to stop working and supplying water. Summary of the Invention

[0013] The technical effects and advantages of this invention are as follows:

[0014] This invention, by incorporating a water flow detection device and a first conductive wire, facilitates the following: When water flows into the first transparent tube through the second transparent tube, and the water pressure is insufficient to lift the second disc and push the top rod, causing the top block of the sleeve to contact the protrusion and transmit an electrical signal to the transmission end, resulting in erroneous data, the water flow detection device detects the water flow inside the first transparent tube and transmits the collected data directly to the transmission end via the first conductive wire. The machine and water pump then receive the electrical signal to correct the error and continue operation. If the water flow detection device detects no water flow and the transmission end also fails to detect water pressure, the electrical signal transmitted to the machine and water pump will stop operation. Furthermore, personnel can directly observe the first and second transparent tubes to inspect their interiors. This effectively prevents erroneous electrical signal data caused by relying solely on the transmission end to detect internal water pressure, which could lead to water being trapped inside the tubes, damaging the machine and affecting its lifespan.

[0015] This invention, by incorporating an air pump, a second wire, a first round rod, and a first connecting rod, facilitates the following: When water flow through the first transparent round tube is too low to be detected by the transmission end, a water flow detection device detects the presence of water flow, albeit at a low flow rate. The electrical signal data is then transmitted via the second wire to the solenoid valve, and the air pressure inside the air pump is transmitted through an air pipe to the nozzle. This air pressure impacts the inner wall of the second transparent round tube, clearing blockages and increasing water flow, thus drawing the blockages into the inner cylinder. The motor housing then drives the rotating shaft and the first connecting rod to rotate. During rotation, the curved paddle at the bottom of the first connecting rod drives the second round wheel through a groove to contact one side of the curved rack block, causing it to rotate inside the third transparent round tube. Simultaneously, the rotation is also driven by the first round rod, which moves the first round wheel along the inner cylinder... The inner wall rotation grinds up the blockages, which are then filtered through the filter holes on the filter disc to the next filtration stage. This reduces the blockages that accumulate in the first and second transparent round tubes due to prolonged water flow, causing a drop in water flow and pressure. When water flows through the first transparent round tube, it cannot transmit an accurate signal by detecting the internal water pressure. The air pump pressurizes the water and transmits it through the air pipe to the nozzle, clearing the blockages from the inside of the first and second transparent round tubes. This effectively removes the blockages and restores water flow, preventing water blockage, machine damage, and incorrect signal transmission. Driven by the first connecting rod, the inner cylinder rotates, and the blockages reach the inside of the inner cylinder. The first wheel and the rotation of the inner cylinder further decompose the blockages, making the next filtration stage more thorough. Excessive blockages are quickly blocked in the next filtration stage, extending the service life of the next filtration stage. Attached Figure Description

[0039] Working principle of this invention:

[0040] S1. When using this low-pressure switch, first connect the water source pipe to the first transparent round pipe 7, and then connect the purifier water pipe to the third transparent round pipe 11. Under normal circumstances, when water flows through the second transparent round pipe 8, it reaches the first transparent round pipe 7. The water pressure inside the first transparent round pipe 7 lifts the second disc 507 and the top rod 505, causing the top block 503 of the round sleeve 504 to contact the protrusion 201, transmitting the electrical signal to the inside of the transmission end 3, and then to the machine and water pump. The machine receives the electrical signal, causing the water source to be filtered and purified, and then the water pump supplies water to the household. When the water flow reaches the inside of the first transparent round pipe 7, if there is insufficient water pressure, the second disc 507 and the top rod 505 will be lifted, causing the top block 503 of the round sleeve 504 to contact the protrusion 201, transmitting the electrical signal to the inside of the transmission end 3, and then to the machine and water pump. The machine receives the electrical signal, causing the water source to be filtered and purified, and then to the water pump to supply water to the household. When the water flow reaches the inside of the first transparent round pipe 7, if there is insufficient water pressure, the second disc 507 will be lifted, and the water pressure will reach the first transparent round pipe 7. When the disc 507 and the push rod 505 lift the top block 503 of the sleeve 504 to contact the protrusion 201, the electrical signal is transmitted to the inside of the transmission end 3. This signal is then transmitted through the water flow detection device 13 to the first transparent pipe 7. The collected data is directly transmitted through the first wire 4 to the inside of the transmission end 3, and then to the machine and water pump. The machine receives the electrical signal and corrects it before continuing operation. This prevents the transmission end 3 from detecting incorrect water pressure signals, which could cause the machine and water pump to stop working even though there is water in the pipe. The trapped water inside could damage the machine and shorten its lifespan. Furthermore, if the transmission end 3 fails to detect water pressure or water flow... The water flow detection device 13 detects a very low water flow rate. It detects that there is water flow inside, but the flow is very low. The electrical signal data is transmitted through the second wire 14 to the solenoid valve 15. The air pressure inside the air pump 9 is transmitted through the air pipe 12 to the nozzle 801. The air pressure impacts the inner wall of the second transparent tube 8 to both sides, clearing blockages inside the second transparent tube 8, increasing the water flow, and driving the blockages into the inner cylinder 112. The motor housing 17 then drives the rotating shaft 16 and the first connecting rod 161 to rotate. During rotation, the bent lever 1 at the bottom of the first connecting rod 161... 62 drives the second wheel 1623 through the groove 111 to reach one side of the curved rack block 20 and make contact, causing the inner cylinder 112 to rotate inside the third transparent tube 11. While rotating, it will drive the first wheel 1145 along the inner wall of the inner cylinder 112 through the first rod 114 to grind the blockage. Then, it will be filtered through the filter holes 191 on the surface of the filter disc 19 to the next process of filtration.
