Abstract
Disclosed is an automatic warning device after an Mg-rod of an electric water heater is completely consumed. Wherein, a hollow pipe with a small hole arranged at the upper of a pipe wall and a mouth arranged at the lower part is inserted into the Mg-rod; a hollow joint is fixed at the position where the lower end of the hollow pipe stretches out of the Mg-rod; the external thread to connect an inner container of the electric water heater with the hollow joint is arranged on the hollow joint; a bulkhead with two conduction rods arranged is screwed into the hollow joint and presses a conduction slice with a certain flexibility and a soft temperature-resistance silica gel cushion into the hollow joint; a pressure cavity is formed between the intra-cavity of the conduction slice and the hollow joint; a warning circuit composed by in serial connection of a power source and a buzzer is connected with tail ends of two conduction rods of the bulkhead; a return spring is arranged between an inner concave face of the conduction slice and the bulkhead. The utility model can correctly check out if the Mg-rod inside the electric water heater is completely consumed so that people can change the Mg-rod in time to prolong the service life of the inner container of the electric water heater. The utility model has the advantages of simple structure, low manufacturing cost and reliability for working.
Description
Technical field
The world today is along with the enhancing gradually of people's environmental consciousness, and the high speed development of State Grid's industry uses the electric water heater of not tool pollution more and more universal in people's daily life.The inner bag of electric water heater can be divided into stainless steel inner container substantially and roll plate and burn enamel ccating inner bag two big classes aspect manufactured materials on the market at present.Stainless steel inner container production cost height, heat-insulating property is poor, and also there is the rust corrosion problem in weld seam.And it is low to roll plate burning enamel ccating inner bag production cost, and heat-insulating property is better than stainless steel inner container, but improves enamel technology in any case, all can't improve at present the easy corrosive defective of enamel micropore both at home and abroad.In order to prolong the work-ing life of enamel inner container; electric water heater manufacturing enterprise mostly adopts and insert the magnesium rod in the electric water heater enamel inner container at present; method with electrochemistry sacrificial anode magnesium rod is protected enamel inner container, and in order to prolong guard time, the magnesium rod is also made increasing.But vast in territory because of China, each sheet water quality mineral of the four corners of the world differs greatly.The spending rate of magnesium rod is by multiple factor decision such as water quality, use temperature, frequency of utilization in addition.How to strengthen magnesium rod weight, also can't dope the replacement cycle of magnesium rod exactly as manufacturer, therefore accurately judge whether the magnesium rod that is contained in the inner container of electric water heater is exhausted and in time changes, for the work-ing life that prolongs inner container of electric water heater be a key problem extremely to be solved.
Summary of the invention
Goal of the invention of the present utility model provides electric water heater magnesium rod that whether a kind of magnesium rod that can accurately detect in the inner container of electric water heater the be exhausted autoalarm that is exhausted, so that people in time change the magnesium rod, prolongs the work-ing life of inner container of electric water heater.
In order to realize the foregoing invention purpose, the technical scheme that the utility model adopted is: insert tube wall upper end and have aperture in the magnesium rod, the open tube of lower ending opening, the position that the magnesium rod is stretched out in described open tube lower end is fixed with a hollow joint, is shaped on the outside screw that it is connected with inner container of electric water heater on the described hollow joint; The plug that two conducting rods are housed on it screws in the hollow joint, and will have certain elastic conducting strip and be pressed in the hollow joint; Wherein form pressure chamber between the inner chamber of conducting strip and hollow joint; The tail end of two conducting rods on plug is connected to by power supply and the placed in-line warning circuit of hummer.
In order to improve sealing property of the present utility model, the further technical scheme that adopts: on described conducting strip, be provided with a soft heat-resistant silicon glue gasket that compresses by plug.
In order to make described conducting strip return effectively, the utility model can also be equipped with return spring between the inner concave of conducting strip and plug.
The utility model can be installed in any position of inner container of electric water heater, obstruction that also can the double as mudhole.When the electric water heater works better, the aperture that inserts on the open tube of magnesium rod is covered by the magnesium rod, and water can not enter pressure chamber in the hollow joint by open tube.Along with the continuous increase of duration of service, number of times, the magnesium rod is constantly consumed.When the aperture on the open tube exposed, the water in the inner container of electric water heater formed the pressure consistent with inner container of electric water heater under pressure promptly in the pressure chamber of aperture in open tube arrives hollow joint, and in pressure chamber.Under this pressure action, be positioned at the swollen distortion of rising of soft heat-resistant silicon glue gasket of pressure chamber below, promoting resistance that conducting strip under the soft heat-resistant silicon glue gasket overcomes return spring is close on two conducting rods on the plug, with conducting by power supply and the placed in-line warning circuit of hummer, remind the human consumer in time to change the magnesium rod, reach the prolongation inner container of electric water heater purpose in work-ing life.The utlity model has simple in structure, low cost of manufacture, work is advantage effectively reliably.

Embodiment
The autoalarm that is exhausted of electric water heater magnesium rod as shown in Figure 1, it is to insert tube wall upper end to have aperture 2 in magnesium rod 1, the open tube 3 of lower ending opening, the position that magnesium rod 1 is stretched out in open tube 3 lower ends is fixed with a hollow joint 4, is shaped on the hollow joint 4 and makes its outside screw that is connected with inner container of electric water heater 5; The plug 8 that two conducting rods that are made of copper 6,7 are housed on it screws in the hollow joint 4, and will have necessarily elasticly, and conducting strip 9 and the soft heat-resistant silicon glue gasket 10 made by copper sheet are pressed in the hollow joint 4; Wherein form pressure chamber 11 between the inner chamber of conducting strip 9 and hollow joint 4; Soft heat-resistant silicon glue gasket 10 is positioned at the top of conducting strip 9, between the inner concave 12 of conducting strip 9 and plug 8 return spring 13 is housed.The tail end of two conducting rods 6,7 on the plug 8 is connected to by power supply 14 and hummer 15 placed in-line warning circuits.Certainly hummer 15 can substitute with warning light.
