Description
Technical field
The utility model relates to a kind of water heater product, particularly relates to a kind of two inner-tube structures of electric heater.
Background technology
Electric heater has become requisite a kind of household electrical appliance in people's life now, and electric water heater with dual inner containers is then because its Intelligent heating and energy-conserving and environment-protective etc. enjoy favor.Two inner bags of current electric water heater with dual inner containers are mostly the integrated liner be welded by two independent inner bags, non-dismountable, the two inner bag of such integral type is easy to use, good airproof performance, but because it is non-dismountable, also there is the problem such as transport inconvenience and maintenance trouble, this also makes two inner-tube structures of present electric heater there is certain deficiency simultaneously.
Summary of the invention
The purpose of this utility model is just the two inner-tube structures providing a kind of electric heater in order to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises upper inner-liner, bottom inner container and cutting ferrule straight coupling, two upper inner-liner joints are provided with in the downside of described upper inner-liner, the upside of described bottom inner container is provided with two bottom inner container joints, and described upper inner-liner joint and bottom inner container joint are provided with external screw thread; Described cutting ferrule straight coupling comprises screwed pipe and nut, and described nut has two, is separately positioned on the two ends of screwed pipe, and described upper inner-liner is connected by cutting ferrule straight coupling with bottom inner container; Be respectively arranged with heater in described upper inner-liner and bottom inner container, the downside of described bottom inner container is provided with magnesium rod, water inlet pipe and outlet pipe.
Further, described upper inner-liner joint and bottom inner container joint are hollow tube, and the internal diameter of upper inner-liner joint and bottom inner container joint and external diameter are equal all respectively.
Further, the internal diameter of described screwed pipe is equal with the internal diameter of upper inner-liner joint and bottom inner container joint.
Further, the upper end of described magnesium rod and water inlet pipe all extends in bottom inner container, and the upper end of described outlet pipe extends in upper inner-liner.
The beneficial effects of the utility model are:
The utility model is a kind of two inner-tube structures of electric heater, and compared with prior art, the utility model utilizes cutting ferrule straight coupling two inner bags to be connected and through, be easy for installation and removal, be convenient to cleaning maintenance, structure is simple, easy to use, there is the value applied.
Accompanying drawing explanation
