R & gel head for aquarium heaters with adjustable degrees Description:

The innovation is a heater head _s consisting of a rotatable upper part and a lower part which is fixedly mounted on one of the known heating rods of glass or metal and
Turning regulates the temperature.

The innovation made the task a lay safe, more comfortable one & · And more visible temperature setting for aquarium heaters solved.

; Heaters are known, the temperature setting being controlled by a

small button with a diameter of 5 - 6 mm. This
ΐ Button muli, however, must be attached under a rubber cover

j is used to keep the heater watertight. Dadurci will die

Temperature setting considerably more difficult compared to the innovation, first of all by the small button and further by the obstructing one Rubber hood. In addition, the temperature setting can be made at

«The previous heaters only felt emotionally, while with the

Ii innovation the upper half (1) of the heater head on the lower part (2)

^f is rotated while sitting, the upper half being clearly laid out

} Has degree scale (3).

In addition, aquarium heaters are known, which are made by rotating

\ of the head can be regulated, but the attached graduation is very deep in the head and is therefore hardly or not at all visible, especially when the heater head is attached below the water level.

In addition, with the known heaters, the regulation can be easily turned over, so that either a low or too high one
Temperature arises, which can be dangerous to the aquarium fish and plants.

The innovation, on the other hand, has a sturdy lock, which is a
Overwinding made impossible by the fact that the rotatable

The heater head {1) has a bead (4) which, when turned, touches the
Bead (B) abuts within the lower part.

Another advantage is that the Stromkäbei (12) is not Ublieh from above but rather laterally opens _{* as will be better placed so that the heater "in the aquarium kanni

The function is "W.ie föl gti,

A regulating pin or spindle (6) reaching out of the heater head presses more or less on a bimetallic strip (7) which is usually shaped for this purpose and which is mounted on the chassis (13) and gives electricity to the heating cartridge in a known manner. So that fine adjustment can be made through simple operation, a gear (8) is fixedly mounted inside the rotatable head in the center, which moves a gear (9) by turning, which is located on the regulating pin or spindle (6). By the screw thread (10), which is located in the lower part (2) of the head, lowers or lifts the pin, creating a bimetal is set in function i

Regulation:

The rotatable upper part (1) is supported by a centered pin a lens head (11) held on the lower part, the pin can be screwed in by means of a thread in the lower part or glued in a groove.

The glass cylinder (16), in which the chassis (13) and the heating cartridge are installed as usual, is pressed into the annular groove (14) and glued in it, while the O-ring (15) for a provides additional sealing against water ingress.
