Description

Technical Field

[0001] This invention relates to the field of scale prevention technology for PTC heaters, specifically a device that uses strong convection to prevent scale formation. Background Technology

[0002] PTC electric heaters, also known as PTC heating elements or PTC heaters, use high-quality PTC thermistor ceramic heating elements as the heat source. They are assembled from corrugated aluminum strips through high-temperature gluing, welding, and molding. They utilize national standard high-temperature resistant insulating brackets, with screw hole spacing for easy customer assembly. Over-temperature protection terminals are securely connected, preventing loosening or detachment. Terminal silicone sleeves with excellent high-temperature resistance, corrosion resistance, and flame retardant properties are used. PTC heaters feature automatic temperature control, rapid heating, and energy efficiency. They utilize a PTC heating element as the heat source and corrugated aluminum alloy fins as the heat sink, assembled using Zhishuo Factory's unique sandblasting cleaning process, high-temperature brazing, and molding. They boast a long service life (over 10 years of continuous use), energy saving, no open flame, no oxygen consumption, high safety, automatic heat output adjustment, and minimal impact from power supply voltage fluctuations—advantages unmatched by other traditional electric heating devices.

[0003] In the existing technology, PTC water heaters input water into the PTC flow tube through the inlet pipe during use. The water undergoes heat exchange as it flows through the PTC flow tube, and then outputs water from the outlet pipe, thus realizing the heat input or output of the PTC water heater. However, in the existing technology, impurities are easily deposited when water flows through the ring and bends inside the PTC flow tube. In particular, scale tends to accumulate in the PTC flow tube of PTC water heaters that have been used for a long time, which prevents water from flowing in the PTC flow tube and affects the normal use of the PTC water heater.

[0007] As a further embodiment of the present invention: a heat-conducting grid is fixedly connected inside the PTC flow tube ring body, one side of the heat-conducting grid is fixedly connected to the second cover plate of the flow tube, and the side of the heat-conducting grid away from the second cover plate of the flow tube is movably connected to the first cover plate of the flow tube.

[0010] As a further embodiment of the present invention: the first cover plate of the flow tube includes a first cover plate body and a plate body sleeve, the second cover plate of the flow tube includes a second cover plate body and a plate body insert rod, the plate body sleeve is fixedly connected to the first cover plate body, the plate body insert rod is fixedly connected to the second cover plate body, and the plate body insert rod is adapted to the plate body sleeve.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. Because an anti-scaling mechanism is installed at the bend of the PTC flow tube, the rotation of the active bevel gear drives the rotation of the transition bevel gear, which in turn drives the rotation of the driven bevel gear, which in turn drives the rotation of the anti-scaling disc. After the anti-scaling disc rotates, it guides the water flow into the flow enhancement tank, accelerates it, and then discharges it from the flow enhancement tank. This creates strong convection at the bend of the ring tube and forces the water flow to accelerate, thus solving the problem of scale blockage affecting the use of PTC water heaters after long-term use in the existing technology. 2. Since the PTC flow tube, the first cover plate of the flow tube, the second cover plate of the flow tube, and the heat dissipation fins are all made of brass alloy, the PTC water heater has high heat exchange efficiency during use. Furthermore, due to the setting of the heat conduction grid, heat can be better output from the PTC flow tube to the first cover plate and the second cover plate of the flow tube, resulting in faster heat dissipation and better efficiency. 3. Since the active bevel gear drives multiple transition bevel gear mechanisms to rotate, and the transition bevel gear mechanisms drive multiple anti-scaling mechanisms to rotate, the anti-clogging effect inside the PTC flow tube ring can be achieved with less energy, resulting in good anti-clogging effect and energy saving.

[0029] The working principle of this invention is as follows: In the prior art, during the use of a PTC water heater, water is introduced into the PTC flow pipe 1 through the inlet pipe 15. During the flow of water in the PTC flow pipe 1, heat exchange is completed, and then the water is output from the outlet pipe 16, thus realizing the heat input or output of the PTC water heater. However, in the existing technology, impurities are easily deposited when water flows through the ring tube body and bend tube body 13 inside the PTC flow tube 1. In particular, scale is easily accumulated in the PTC flow tube 1 of PTC water heaters that have been used for a long time, which causes the water to not flow in the PTC flow tube 1 and affects the normal use of the PTC water heater.

[0030] This application features an anti-scaling mechanism 8 at the bend of the PTC flow pipe 1. The active bevel gear 21 rotates, which in turn drives the transition bevel gear 25 to rotate. The transition bevel gear 25 then drives the driven bevel gear 81 to rotate, which in turn drives the anti-scaling disc 83 to rotate. The anti-scaling disc 83 then guides the water flow into the flow enhancement tank 84, accelerates it, and then discharges it from the flow enhancement tank 84. This creates strong convection at the bend of the bevel and forces the water flow to accelerate, thus solving the problem of scale buildup affecting the use of PTC water heaters after prolonged use in the prior art. Furthermore, the PTC flow tube 1, the first cover plate 3 of the flow tube, the second cover plate 4 of the flow tube, and the heat dissipation fins 9 are all made of brass alloy. Therefore, the PTC water heater has high heat exchange efficiency during use. Moreover, due to the setting of the heat conduction grid 7, heat can be better output from the PTC flow tube 1 to the first cover plate 3 and the second cover plate 4 of the flow tube, resulting in faster heat dissipation and better efficiency. Since the active bevel gear 21 drives multiple transition bevel gear mechanisms 22 to rotate, and the transition bevel gear mechanisms 22 drive multiple anti-scaling mechanisms 8 to rotate, the anti-clogging effect inside the PTC flow ring body 11 can be achieved with less energy, resulting in good anti-clogging effect and energy saving.
