Abstract
The utility model relates to an alarm for lack of water of an electric heating thermos bottle. When water in the utility model is insufficient, the utility model can emit an alarm signal. The utility model is provided with a float which is provided with a magnetic steel and can float at a water surface of a glass pipe of an electric heating thermos bottle, and a magneto resistor which is fixed on the outer wall of the lower part of the glass pipe where the float is positioned by a fastener. The magneto resistor is connected with a signal comparator circuit, an alarm circuit and a buzzer through conducting wires, which forms an alarm system. The utility model has the advantages of simple structure, few electronic elements which are required, easy assembly, high sensitivity, loose requirements for magnetic signals, and high working temperature. The function of the magnetic steel can not be influenced by fouling. The service life is lasted by more than 50 thousand hours.
Description
The utility model belongs to the magneto-dependent sensor applied technical field, sends the electric hot water bottle water insufficiency alarm device of alarm signal when relating to a kind of domestic electric heating water bottle lack of water.
In the electric hot water bottle structure of existing market, add the water prompting and generally use scale method, utilize law of connected vessels exactly, when the water level of glass tube dropped to the transparent place of electric hot water bottle shell and is marked with the scale that adds the water prompting, the user added water after finding by naked eyes, just finds not have water when perhaps taking out not water outlet, the water level that adds glass tube is not obvious, be difficult for seeing clearly, make troubles to the user easily or cause water pump idle running and shorten the water pump life-span, even may cause the undue heating of insulation heater circuit and burn out.China utility model patent specification CN2296156Y discloses a kind of lack of water power alarm electric hot water bottle, and the warning system of this electric hot water bottle is by probe, and control circuit board is formed, and probe is contained in the electric hot water bottle water tank.After this device uses a period of time, probe incrustation, sensitivity reduces and makes warning system malfunctioning.
The purpose of this utility model is to provide a kind of electric hot water bottle water insufficiency alarm device of highly sensitive, long service life.
For achieving the above object, electric hot water bottle water insufficiency alarm device of the present utility model has one to have magnet steel 3 and can be suspended in the float 2 that electric hot water bottle shows water glass 1 water surface, be fixed in the metallic film mistor 5 of glass tube bottom, float 2 place outer wall by securing member 10, this metallic film mistor 5 connects signal comparator circuit 6, warning circuit 7, buzzer 9 through lead and forms warning systems.
Above-mentioned warning system can also connect the relay 8 of a control electric hot water bottle heat tracing system and pump power.
Above-mentioned float can be made with plastics, rubber type of material such as the ABS plastic of the above temperature of nontoxic, anti-100.Float 2 is positioned in the thermos bottle demonstration water glass 1 during installation, and mistor 5 is fixed on thermos bottle by securing member 10 and shows water glass 1 bottom outer wall; If electric hot water bottle shows that water glass 1 is also used as drainpipe, can when making electric hot water bottle, add the glass tube of a two ends joining water box 12, float 2 is positioned in this additional glass pipe, and mistor 5 is fixed in the bottom outer wall of this additional glass pipe by securing member 10.
Above-mentioned signal comparator circuit 6 and warning circuit 7 all are control circuits commonly used.Electric hot water bottle manufacturing firm can be integrated signal comparator circuit, warning circuit, the relay of heat tracing circuit system and the utility model device when wiring board is made.
Electric hot water bottle water insufficiency alarm device of the present utility model is simple in structure, and required electronic component is few, and easily assembling, volume are little, in light weight, and the magnet steel effect is not influenced by incrustation, and is highly sensitive, magnetic signal is required not tight, the operating temperature height, the life-span is more than 50,000 hours.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model apparatus structure and user mode schematic diagram.
As Fig. 1, only be used to show that the glass tube 1 of water level is positioned at the transparent place of electric hot water bottle shell, the float 2 that has magnet steel 3 is positioned in the glass tube 1, be suspended in above the drinking water 4, metallic film mistor 5 is fixed in glass tube 1 bottom by securing member 10, and metallic film mistor 5 connects signal comparator circuit 6, warning circuit 7, relay 8 and buzzer 9 by lead and forms the power alarm system.When float 2 drops near metallic film mistor 5 with the electric hot water bottle water level; metallic film mistor 5 is changed by the magneticaction resistance value of magnet steel 3; the signal of signal comparator circuit 6 reception metallic film mistors 5 also after treatment; drive warning circuit 7; make buzzer 9 that graceful music sound take place, remind the user to add water, relay 8 actions simultaneously; cut off electric hot water bottle heat tracing system and pump power, thus the protection electric hot water bottle.The utility model device electronic component is few, circuit is simple, can on the line tower foundation of former electric hot water bottle, expand a little, when making wiring board, add signal comparator circuit 6, warning circuit 7, relay 8, the side of occupation of land not, do not influence former line parameter circuit value, former electric hot water bottle buzzer also can be also used as the buzzer of the utility model device.
If former electric hot water bottle shows that water glass 1 is also used as drainpipe, can add a upper end joining water box 12 tops, the glass tube of lower end joining water box 12 bottoms, float 2 places this additional glass pipe, and metallic film mistor 5 can be used by the bottom outer wall that securing member 10 is fixed in this additional glass pipe.
Claims (2)
