Abstract
A kind of float type liquid level detects heater.It is in heater main body, to be electrically connected by the order of float-type transmitter, temperature sensor, heating wire and governor circuit.On Software for Design; governor circuit preferentially analyzes the liquid level information of float-type transmitter; temperature sensing portion is in sub-priority; the water temperature for avoiding liquid level from being caused when being less than temperature sensor raises, damages heater, even causes fire extremely; and current loop is not produced in course of work liquid, protect all kinds of aquariums to current sense biological.
Description
Technical field
The utility model is related to a kind of attemperating unit, more particularly to a kind of float type liquid level detection heater.
Background technology
At present, the water heating function in aquarium relies primarily on electric heater unit to operate.It is most common on the market at present
Electric heater unit rely primarily on bimetal leaf or digital temperature sensor detection temperature signal, it can be in time according to preset temperature
Control is heated and shows water temperature, but due to the natural requirement of the type design, temperature detecting point needs to separate with heating part（Carry
The stability of heating process high）, but when natural evaporation or aquarium change water, water level adds less than in the case of temperature sensor
Thermal continuous firing, will cause water temperature to raise extremely, threatens aquarium fish safety, damage heater, even cause fire
Calamity.Modified temperature-adjusting heating device is also occurred in that at present, the advantage of former heater is drawn, and further it is by by aquarium
As detection conductor, when liquid level is higher than test point, detection electric current flows through liquid in aquarium, the normal work of electric heater unit to liquid
Make, on the contrary shut-off, so as to realize the function of water shortage power-off.But because fish are very low to electric tolerance level, 90 microamperes can make fish
Class tends to trip to anode even death extremely, and 1/10th electric current can make Fish behavior exception, be measured using metal probe
The mode of water resistance forms current loop in water, and easily fish in aquarium are caused safely to have a strong impact on.
The content of the invention
The utility model provides a kind of float type liquid level detection heater, to solve the above problems.
To achieve the above object, the utility model provides following technical scheme：A kind of float type liquid level detects heater,
It include main control board, the middle part that the main control board is placed in host glass pipe, main control board respectively with main body on
Square float-type transmitter, body interior top temperature sensor, main body inner bottom part electrical heating wire are connected, wherein main control board
Upper integrated temperature display.Float-type transmitter and temperature sensor are all placed in body top, and wherein float-type transmitter is put and answered
Higher than temperature sensor.Software logic requirement：The detection signal of float-type transmitter is priority, and temperature detection signal is secondary
Level.Only float-type transmitter pass back liquid level reach requirement when just start working, and then judge temperature signal, decide whether to touch
Generating heated filament works.
It constantly returns to main control board using the water level detecting function of float-type transmitter, and main control board is made
Judge and send order.Worked when only liquid level is higher than water level detecting point in aquarium, when liquid level descends below water level detecting point
When be automatically stopped work.Fish in the characteristics of not forming current loop in water using float-type transmitter, effectively protection aquarium
Class, while the logic flow of governor circuit can realize the purpose of heated constant temperature.
Technique effect of the present utility model and advantage：The aquarium heater, it is possible to achieve heated at constant temperature, display temperature
Degree；Exchange water, evaporation etc. cause the situation that liquid level declines to judge and be stopped immediately, effectively protect heater, water
Fish in race's case；Avoided to current loop is introduced in aquarium using float type level gauge simultaneously, ensured in aquarium to electricity
Flow sensitive fish.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is structure principle chart of the present utility model.
In figure：1 float-type transmitter, 2 temperature sensors, 3 host glass pipes, the governor circuit of 4 integrated temperature displays
Plate, 5 thermal insulative boards, 6 heating wire.
Specific embodiment
With reference to the accompanying drawing in the utility model embodiment in Fig. 1, float-type transmitter（1）, temperature sensor
（2）With main control board（4）Parallel connection, main control board（4）Only detect float-type transmitter（1）Liquid level is passed back normally to believe
Breath, starts analysis temperature sensor（2）With the difference of preset temperature, decide whether to trigger heating wire（6）, while main control board
（4）The temperature that will be collected show with temperature indicator integrated thereon on, thermal insulation board（5）Mainly act on bottom heating wire temperature
Degree does not influence main body normal work.
