Description
Technical field
The utility model belongs to electric heater technical field, more particularly to a kind of electric heater that function is detected with magnesium rod.
Background technology
In order to reduce the corrosion of storage-type electric water heater, current main product protects inner bag, i.e. sacrificial anode using magnesium rod
Cathodic protection, the inner bag of water heater is protected by preferentially corroding magnesium rod.During storage-type electric water heater use, magnesium rod can be slowly
Depleted, many factors such as the life-span of magnesium rod and its length, diameter, the water temperature of water tank, water quality are relevant, therefore the use of magnesium rod
Life-span can not be accurate.If after magnesium rod runs out of, magnesium rod replacing is carried out not in time, water heater liner will be corroded, and have a strong impact on it
Service life.
Utility model content
The purpose of this utility model is：There is provided one kind there is magnesium rod to consume inspection for problems of the prior art
The electric heater of brake, the water heater can reflect the Expenditure Levels of magnesium rod in time.
To achieve these goals, the technical solution adopted in the utility model is：
Electric heater described in the utility model includes inner bag, magnesium rod, electric-controlled plate, and the magnesium rod and the electric-controlled plate pass through the
One signal wire is connected, and the inner bag is connected with the electric-controlled plate by secondary signal line；
The magnesium rod includes self-locking nut a, binding post, self-locking nut b, screw head, connecting rod, rod core, and the rod core is equal
It is even that magnesium is distributed with；The connecting rod outer ring coats sealing rubber cover, and the upper end of the sealing rubber cover is connected with nylon felt pad
Connect, the other end of the nylon felt pad is connected with plain cushion, spring washer in turn；The connecting rod is connected with the rod core.
Further, the rod core is steel core.
By adopting the above-described technical solution, the beneficial effects of the utility model are：Screw head and magnesium rod main body are carried out exhausted
Edge is isolated, and after magnesium rod is corroded, is there is faint voltage signal between magnesium rod and inner bag, by being changed to the signal, is made
Obtaining the Expenditure Levels of magnesium rod can intuitively show, and facilitate user to change magnesium rod in time, in case electric heater is damaged.

Embodiment
With reference to Fig. 1 and 2, electric heater described in the utility model includes inner bag 12, magnesium rod 13, electric-controlled plate 15, the magnesium rod
13 are connected with the electric-controlled plate 15 by the first signal wire 14, and the inner bag 12 passes through secondary signal line 16 with the electric-controlled plate 15
Connection；
The magnesium rod 13 includes self-locking nut a 1, binding post 2, self-locking nut b 3, screw head 7, connecting rod 8, rod core 10,
The rod core 10 is evenly distributed with magnesium 11；The outer ring of connecting rod 8 coats sealing rubber cover 9, the upper end of the sealing rubber cover 9
It is connected with nylon felt pad 6, the other end of the nylon felt pad 6 is connected with plain cushion 5, spring washer 4 in turn；The connecting rod 8
It is connected with the rod core 10.
Further, the rod core 10 is steel core.
Operation principle：Screw head 7 and magnesium rod connecting rod 8 are dielectrically separated from, after magnesium rod is corroded, magnesium rod 13 and inner bag
There is faint voltage signal between 12, by being changed to the signal so that the Expenditure Levels of magnesium rod 13 are on electric-controlled plate 15
Can intuitively it show,
The method of described electric heater detection magnesium rod consumption, comprises the following steps：
SP1. when needing detection, the voltage between the first signal wire 14 of collection of electric-controlled plate 15 and secondary signal line 16 is started
Signal is simultaneously automatically connected into sampling resistor, and its voltage signal is converted into current signal, and the microprocessor of electric-controlled plate 15 is believed electric current
Number sampled；
SP2. electric-controlled plate 15 is gathered once per 100ms, after the efficiently sampling time 300s is reached, takes all collections in 300s
To the average value of current value, this is sampling 1 time, when the current signal collected for continuous 3 times is below 0.25mA, electric-controlled plate 15
Display screen carry out alarm indication, point out as early as possible change magnesium rod.
