Description

A kind of fish tank thermostat

Technical field

The utility model relates to a kind of fish tank thermostat of fish jar water temperature in constant scope that be used to keep, and is the technology that belongs to the fish jar ecological environment optimization.

Background technology

Fish jar can beautifying household environment, and for the requirement that the water frequency is changed in the demand that adapts to water saving and minimizing, fish jar generally all has a water filtering system, the water in the fish jar constantly is pressed onto in the filtering trough filters, and flows back in the fish jar again, changes the frequency of water with minimizing.

The fingerling that has some that water temperature is had relatively high expectations except water will filter, also will keep water temperature in stable scope, the water temperature height not all right, low also not all right.What adopt on the market at present generally is the mode of heating rod, and advantage is that cost is lower, and shortcoming is that water temperature range control is accurate inadequately, and directly is immersed in the water in the fish jar, influences the attractive in appearance of fish jar.

In the patent No. be 99216523.7Patent in the electronic type fish jar constent temperature heater issued, and the patent No. is the fish jar constent temperature heater of being issued in 02245863.8 the patent, all has only heating function, there is not refrigerating function, therefore, when water temperature is higher, just can't keep the constant of water temperature.

A kind of aquarium thermostat is disclosed in the patent No. is 02206085.5 invention, be the water in the aquarium is freezed or to heat by being installed in cold and hot mapping device in the ventilation casing, advantage is that heating function is not only arranged, also have refrigerating function, can keep water temperature constant, shortcoming has two, the one, adopt closed water treatment, promptly need to be installed into outlet pipe, make the water in the aquarium enter this aquarium thermostat, flow back to aquarium after treatment again; The 2nd, complex structure, cost is higher.

Therefore, it is constant to need to seek a kind of water temperature that can either keep, and does not need to be installed in addition the fish tank thermostat of outlet pipe again.

Summary of the invention

It is constant that the purpose of this utility model provides a kind of water temperature that can either keep, and do not need to be installed in addition the fish tank thermostat of outlet pipe again.

The technical solution adopted in the utility model is: a kind of fish tank thermostat, mainly by shell 1, be provided with the casing cover 2 of air vent, feet 3, temp probe 4, water level switch 5, radiator 6, blower fan 7, radiator 8, auxiliary heater 9, control circuit board 10, peltier-element 11, control panel 12 and power panel 13 are formed, temp probe 4, water level switch 5, auxiliary heater 9 is connected with control circuit board 10, and in shell, extend to outside the shell, described peltier-element 11 is placed in the perforate of shell 1 bottom, one side in the enclosure connects with radiator 6, and the one side outside shell connects with radiator 8.

Described fish tank thermostat is pressed the water inlet of temp probe 4 near filtering trough, and radiator 8 and auxiliary heater 9 are placed on the filtering trough 14 of fish jar near the delivery port of filtering trough.

Described feet adopts the adjustable support pin, and the height of feet arrives 40mm at 15mm.

The input of described control circuit board 10 connects with control panel 12 and power panel 13, and output connects with the two poles of the earth, auxiliary heater 9 and the control panel 12 of blower fan 7, peltier-element 11.

The beneficial effects of the utility model are: can keep water temperature constant, and cost simple in structure lower, do not need construction and installation, the fish tank thermostat of popularization and application easily.

1, by the exchange of control peltier-element the two poles of the earth both positive and negative polarity, realization is freezed to the water that flows through in the filtering trough or is heated, thereby water temperature is constant in the maintenance fish jar;

2, install and use simply.Directly fish tank thermostat of the present utility model is placed in the filtering trough of fish jar, and by regulating the height of feet, guarantees the heater of fish tank thermostat below and water level switch is under water gets final product.

Below in conjunction with drawings and Examples the utility model is further specified.

Embodiment

The operation principle of fish tank thermostat of the present utility model:

Variation by the electric power polarity at peltier-element the two poles of the earth is exported in control realizes refrigeration or heating to radiator 8, thereby realizes refrigeration or heating to the water in the filtering trough that flows through radiator 8.

As Fig. 1, Fig. 2, shown in Figure 3, fish tank thermostat of the present utility model, mainly by shell 1, be provided with the casing cover 2 of air vent, feet 3, temp probe 4, water level switch 5, radiator 6, blower fan 7, radiator 8, auxiliary heater 9, control circuit board 10, peltier-element 11, control panel 12 and power panel 13 are formed, temp probe 4, water level switch 5, auxiliary heater 9 is connected with control circuit board 10, and in shell, extend to outside the shell, described peltier-element 11 is placed in the perforate of shell 1 bottom, one side in the enclosure connects with radiator 6, and the one side outside shell connects with radiator 8.

As Fig. 1, Fig. 3 and shown in Figure 4, described fish tank thermostat is pressed the water inlet of temp probe 4 near filtering trough, and radiator 8 and auxiliary heater 9 are placed on the filtering trough 14 of fish jar near the delivery port of filtering trough.

Fish tank thermostat before use, will be in advance according to the requirement of the fish of being supported in the fish jar to water temperature, set the temperature range of water, the water pump in the fish jar filtration system can constantly pump into filtering trough to the water in the fish jar, and the water temperature that temp probe returns is close with the water temperature in the fish jar.

Described feet adopts the adjustable support pin, and the height of feet, is soaked in water to guarantee water level switch, temp probe and radiator to 40mm at 15mm.

The input of described control circuit board 10 connects with control panel 12 and power panel 13, and output connects with the two poles of the earth, auxiliary heater 9 and the control panel 12 of blower fan 7, peltier-element 11.Control circuit board 10 is constantly monitored the value that water temperature and water level switch return, need to judge whether startup work again, start work if desired, control circuit board 10 is by the exchange of the direct current both positive and negative polarity at control peltier-element 11 the two poles of the earth, cause the exchange of peltier-element 11 cooling and warmings, just can realize refrigeration of the water in the fish jar or heating, thereby keep water temperature in the scope of setting.

For bigger fish jar, only settle one group of peltier-element and corresponding radiator in the fish tank thermostat, because power is on the low side to be difficult to keep water temperature in predefined scope, can meet the demands by in fish tank thermostat, settling peltier-element and corresponding radiator more than two groups side by side.

The filtering trough of some fish jar is vertical the arrangement, then can directly be suspended in fish tank thermostat on the fish jar and install, as long as make temp probe 4, water level switch 5 and radiator 8 operate as normal that get final product under water.

Fish tank thermostat of the present utility model is as long as power connection can be worked without manual intervention, easily and effectively fully automatically.

The foregoing description only is to be used for the usefulness of interpretation the utility model; and be not to be to restriction of the present utility model, those skilled in the art are in essential scope of the present utility model; make various variations or alternative, also should belong to protection category of the present utility model.
