[Prior art]

  The current fish tank for ornamental fish does not simply have the function of raising ornamental fish, but rather for indoor use. It also has an application that matches the design and landscape, and the indoor design is attractive due to the aquarium for viewing fish. Will be The maintenance of the fish tank for ornamental fish is emphasized for stable water quality. It is necessary to completely control both the temperature of water and impurities, and The survival of fish and plants can be secured. However, in general, the heater for water temperature control is heated when energized. Although it heats and has a heating temperature setting function, it is not convenient for the user and the rear The current status of the heater during the time, such as the current power supply and non-conduction status, or Can not know if it is currently heating.

[0003]   Also, a well-known heater heats up when energized, and if an excessive load occurs during the heating process. Generally, heaters do not have a safety power cut design, and burn out if the user does not notice. I may end up doing it. In order to solve such safety problems of electricity use, In the field, fuses are used as a structure for heater protection, but fuses are Since it is installed inside, once it is burnt out, the heater must be discarded and repair Cannot be replaced, which not only creates waste, but also puts an unnecessary burden on the user. It was

[Embodiment of device]

  1 and 2 are a schematic view of a specific embodiment of the present invention and an electric circuit diagram thereof. The invention is A circuit board 12 is provided in the glass tube 11, and the heating coil 1 is provided on the circuit board 12. 3 are connected to each other, and a control ring 15 is provided at the upper end opening of the glass tube 11, Thus, the heater 1 for the aquarium for appreciating fish is formed.

[0008]   The glass tube 11 is a tube body having a single opening, and has a circuit board 12 and a heating coil inside. Control ring 15 is housed in the opening at the top, which contains The glass tube 11 is supposed to be in a sealed state.

[0009]   The circuit board 12 has its upper end connected to the control ring 15 and has its lower end heated. The circuit board 12 is connected to the coil 13 and the temperature control means and the temperature detection means ( (Not shown) is provided to detect the water temperature and heat the heating coil 13.

[0010]   The heating coil 13 serves as a heating means such as a heating wire or a heating resistance, and the circuit board 12 And is controlled by it to generate heat.

[0011]   The control ring 15 is mounted on the glass tube 11 to make it hermetic, and The control ring 15 is connected to the circuit board 12 and combined with the control ring 15. The power is input by the code 151, and the user controls the water temperature by using the temperature control rod 152. To serve.

[0012]   The features are as follows. That is, the circuit of the circuit board 12 has a power supply state. Indicator lamp 121 for displaying the, and second display lamp for displaying the heating coil operation. The first display lamp 121 and the second display lamp 122 are different from each other. Between the heating coil 13 and the circuit board 12 Is provided with a protection means 14, and the protection means 14 is a spring type switch. When the load becomes excessive and it overheats, the circuit operates according to the principle of thermal expansion and contraction. Disconnect and restart the circuit after temperature recovery to ensure the safety of the heater and use .

[0013]   The power cord 151 on the control ring 15 is used by the user because it is composed according to the above requirements. Then, input power (connect to P1 and P2), and when connection of power is completed, the first table The indicator lamp emits light to let the user confirm, and the user uses the temperature control rod 152. Then, the required water temperature is set, and the circuit board 12 detects the temperature using the temperature detecting means SR. If the temperature is lower than the set temperature, the heating coil 13 heats it and the fish tank for viewing fish. The temperature of the water is increased, and the circuit is a comparison circuit composed of OP comparators (circuit operation is The detailed explanation is omitted because it is not the focus of the invention) If the temperature is too low, the thyristor TR1 is turned on and voltage is output to M1 and M2. Then, the heating coil 13 is heated and the second display lamp is caused to emit light. On the contrary, times If the temperature detected by the temperature detecting means SR of the road substrate 12 has reached the set temperature, the cycle The lister TR1 is cut and the end points of M1 and M2 are cut into a solid state and the heating coil The heating of the ill 13 is stopped, and the second display lamp 122 goes out.

[0014]   If an overload occurs during operation of the above circuit, the protection means 14 jumps and the input The power supplies P1 and P2 are cut off to cause the circuit board 12 to stop operating.

[0015]

[Effect of device]

  Overall, the structure of the present invention is simple, and when the load of the heater is excessive, a protection device is provided. With this, it is possible to automatically cut off the operation of the circuit and prevent the occurrence of danger.
