Description

Heating wire treatment method for aquarium heating and heater made therefrom

The invention relates to an aquarium heater, especially for the surface treatment of the heating wire, and provides a device that can effectively prevent water seepage and electricity leakage caused by continuous position cracks between the heating wire and the conductive metal wire, making the manufacturing more convenient and reducing the cost. , At the same time greatly improve the use of safe new aquarium heating heating wire processing method and the heater made of it.

The current aquarium heaters will face the safety problem of water leakage and electricity leakage in use. In order to avoid the occurrence of electricity leakage in the past, the outer surface of the heater is covered with enough or multiple watertight insulation measures as much as possible, such as the traditional The single-tube type is to put the connection position of the heating wire and the metal wire into the tube as much as possible, and provide multi-layer watertight protection on the outer cover. Another long-line heater as shown in Figure 8 is covered with Several layers of insulating sheaths are used to achieve the purpose of waterproofing and insulating, but no matter what method is used to make it, the basic manufacturing method is shown in Figure 7. The built-in heating wire has not been subjected to any other waterproofing and insulating treatment before packaging , but directly connected to the conductive metal wire and then put into the tube (or form a sheath on the outside to achieve a watertight package), so once the outer waterproof protection is damaged, there will be a danger of internal water leakage.

Take the above-mentioned long-line heater as an example (as shown in Figure 8), due to its structural design and shortcomings, it is easy to cause damage, water leakage and leakage after long-term use. On the surface of a soft wire (such as glass fiber), the heating wire and the wire are connected to each other with terminals, and then the outer surface is covered with a silicone layer for insulation. Because the connection position is connected by the terminal, it is necessary to apply For a better insulating and protective silicone layer, it is necessary to wrap an inner layer of high-temperature-resistant silicone layer on the connection position where the terminal is located, and then reinforce an outer layer of silicone layer on the outermost surface, so as to make it The formed heater will show non-uniformly formed swollen end joints at the terminal connection position, just like the outlet position of a general-purpose DC transformer, which makes the long-term use bear the bending force and the damage of thermal expansion and contraction when the power is turned off, resulting in The potential danger of water leakage and electricity leakage caused by the rupture of the sheath has become the biggest fatal injury of this product. Therefore, it is very troublesome to apply. Special care must be taken not to let its end joints soak in water to ensure safety. This is why this product has been released for consumption soon. One of the main reasons why people don't use it.

In addition, during the manufacture of this heater, terminals need to be sandwiched between the heating wire and the wire, and the outer surface must be covered with two insulating layers before it can be used. In addition to wasting labor, the manufacturing cost will also increase significantly. One disadvantage.

Although this product has the above shortcomings at this stage, it can still be laid on the bottom of the tank to generate uniform heating in use, so it still has the value of further research and development.

As shown in Figure 1 and Figure 2, the heating wire treatment method designed by the present invention for aquarium heating is mainly to coat the outer surface with a thin, pressure-resistant and heat-resistant insulating layer 13 before the heating wire 1 is packaged. , and then wiring or adding temperature sensing control, after coating the surface layer or putting it into the tube for water-tight packaging, even if the outer sheath 4 of the heater 20 is broken and seeps, the interior can still be wrapped by the insulating layer 13 To effectively prevent leakage and greatly improve the safety of use.

Among them, the insulating layer 13 of the above-mentioned treatment method should be at least able to withstand a withstand voltage of 3.5 kV, for example, it is made of varnish or an equivalent viscous and hard-to-remove material, so that the heating wire 1 can be removed by immersion. A thin isolation coating is formed on the surface, and no leakage will occur under 120°C and 13.5KV high voltage.

Shown in Fig. 2, Fig. 3, Fig. 4 is the concrete example that adopts the method of the present invention to make aquarium warmer, wherein, this aquarium warmer 20 structure mainly comprises:

A heating wire 1 wound on a heat-resistant insulating medium 3, the heating wire 1 is treated by the method of the present invention, and an insulating layer 13 coated with varnish is formed on the outside;

a conductive metal wire 2 entangled with the two ends 11 of the heating wire 1; and

An outer sheath 4 wrapping the two to form the outermost surface insulation.

Wherein, the metal wire 2 is copper wire or tinned copper wire as the best, and the insulating medium 3 is a glass fiber wire, and in order to facilitate winding and obtain good contact conduction, the insulating medium 3 is elongated. The metal wire 2 and the heating wire 1 are respectively wound on the extended dielectric section 31 from different directions on both sides. When winding, the metal wire 2 and the insulating medium 3 can be paralleled and merged first, and then the heating wire 1 is wound on it and tightened at the same time to obtain A period of continuous contact at its best.

Such an efficient design results in a warmer with three useful functions:

1. There is no need to set another plug-in terminal between the heating wire 1 and the conductive metal wire 2, so the assembly steps can be reduced and the cost can be reduced, and a smooth and parallel contact of a certain length can be achieved between each other, forming a good conduction without generating heat in this section Impedance, so there is no usual thermal expansion and contraction to produce damage to the sheath 4.

2. The heating wire 1, the conductive metal wire 2 and their connecting positions have the same surface size, so they can be integrally formed and covered with a single and sufficient outer layer of sheath 4, so that the two ends of the heating wire 11 are connected with the conductive wire. The connection position of the metal wire 2 will not produce the usual swollen end joints, so that the combination of the heater has a consistent integrity, and can effectively avoid water seepage and electricity leakage caused by breakage after long-term use.

3. The part of the heating wire immersed in water is protected by double-layer insulation, so even if the outer sheath 4 is pecked by a fish, it will not damage the inner insulation layer 13, and will not cause leakage. for safety.

In addition, the aquarium heater 20 provided by the present invention can also be set as heaters 20 with different specifications of 24V or 115V-230V through the different material lengths of the heating wires 1 selected inside, and the heater 20 can be energized The temperature of the rear surface is controlled at about 62°C, so that the sheaths 4 will not be damaged by overheating when they collide with each other. In application, it is not necessary to fix it with a bracket to obtain the practical convenience of throwing it into the cylinder and laying it at will. At the same time, it is made of soft insulating adhesive layer. The outer sheath 4 makes the heater immersed in water in a long line and spreads over the entire corner of the bottom of the tank to produce a uniform heating effect, and its connection position can be completely immersed in water when applied, which does not need to be like the existing product at all. The structure must vacate the end joints to ensure safety, which is a major feature of the present invention.

As shown in Figures 5 and 6, the treatment method of the present invention can be universally used on heaters 20 of various shapes, wherein the outer layer 14 of the heater can be made of sheet plastic to cover, so that the heater can be applied It can be pasted on the tank side or laid on the bottom of the tank (as shown in Figure 5) in the form of a whole sheet, or the outer layer 15 of the heater can be manufactured and processed by covering the outer layer 15 of the heater with hard unequal concrete, so that the heater is in the shape of a hard block The reptiles lie down on the hot stones (as shown in Figure 6) to promote their normal excretion.
