Detailed Description

The present invention will be further described with reference to the following examples, which are only part of the present invention, and these examples are only used to explain the present invention, and do not constitute any limitation to the scope of the present invention.

As shown in fig. 1-4, a constant temperature device for a fish tank comprises a housing 1, a control panel 3 is arranged in the housing 1, a heating element 4 connected with the control panel is arranged on the control panel 3, the housing 1 covers the control panel and the heating element and seals the heating element in the housing 1 through an upper shell 2, a water temperature NTC 6 and an indicator light 7 are arranged at the end part of the control panel 3, and the water temperature NTC 6 and the indicator light 7 are covered by a protective sleeve 8 and protrude out of a through hole 21 of the upper shell 2.

Still include the power cord, power cord and control panel 3 are connected with heat-generating body 4, and heat-generating body 4 is wrapped up by shell 1, and shell 1 is inside to be provided with circuit board 3, water temperature NTC 6, pilot lamp 7, prevent dry combustion method NTC 5, heat conduction material 11 and sealing material 12.

The power cord is connected with an external power supply and supplies power to the control panel and the heating body.

The protective sleeve 8 is provided with protruding parts corresponding to the number of the through holes, and the protruding parts are used for respectively covering the water temperature NTC and the indicator lamps. In particular to a sleeve-shaped protrusion 82 covering the indicator light body and a semicircular protrusion 81 of a half-wrapped water temperature NTC head. The protective sheath 8 protrudes through the through hole 21 of the upper case. The water temperature NTC wraps up and the outstanding body alone by the shell for the temperature of the interior water of more accurate response fish bowl, the pilot lamp wraps up and the outstanding body alone by the shell for the work state of instruction heater, the bright red light of heating, the bright green light of non-heating.

As shown in fig. 5-6, the casing 1 is filled with a heat conducting material 11, which is a magnesium sand layer in the embodiment of the present invention, after covering the control board and the heating element.
