The utility model for the technical scheme that solves its technical problem and adopt is: a kind of novel Inlet and outlet water structure of water heater, it comprises the water inlet pipe and water outlet pipe joint, the inner bag water pipe head, inner bag and water pipe, to use direction to be benchmark, described inner bag water pipe head lower end (preferably) is provided with a boss, boss (preferably center) but in be provided with first through hole that proper feed pipe plugs, described water pipe lower end is inserted in first through hole, described water inlet pipe and water outlet pipe upper end of joint is provided with second through hole that just can supply boss to plug, the boss location is inserted in second through hole, detachably fixedly connected with the water inlet pipe and water outlet pipe upper end of joint in described inner bag water pipe head lower end, and water inlet pipe and water outlet pipe joint lower end is provided with the third through-hole that is connected with water pipe, water pipe is connected earlier on the inner bag water pipe head cylinder boss, the water inlet pipe and water outlet pipe joint is connected in the inner bag water pipe head more then, can be by this structure so that the water inlet pipe and water outlet pipe joint has the effect of anti-electrical network, can make the water inlet pipe and water outlet pipe joint again, the inner bag water pipe head, the water pipe fluid-tight engagement prevents to leak.
As further improvement of the utility model, the lower end outer surface of described water pipe is arranged with water pipe sleeve, and water pipe sleeve is in first through hole.
As further improvement of the utility model, described inner bag water pipe head lower end with the mode that the water inlet pipe and water outlet pipe upper end of joint is detachably fixedlyed connected is: inner bag water pipe head lower end medial surface is embedded with internal thread, and the water inlet pipe and water outlet pipe upper end of joint outside is provided with the metal external thread with the internal thread coupling.
As further improvement of the utility model, the junction of described inner bag water pipe head lower end and water inlet pipe and water outlet pipe upper end of joint is provided with first gasket seal.
As further improvement of the utility model, described water inlet pipe and water outlet pipe joint is the integral plastics structure, and makes with metal external thread is one-body molded.
As further improvement of the utility model, the internal diameter of described third through-hole is less than the internal diameter of second through hole, third through-hole is in second through hole fully, and described second and third through hole intersection forms shoulder, is provided with second gasket seal between described water pipe lower end and described shoulder.
As further improvement of the utility model, described water pipe is at least a kind of in cold water water pipe (water inlet pipe) and the hot water water pipe (outlet pipe).
The beneficial effects of the utility model are: the whole plastic material that adopts of water inlet pipe and water outlet pipe joint, threaded portion is inlaid with metal threaded, be formed in one with working of plastics and make, there is a third through-hole lower end, can reduce the Leakage Current of water outlet, the inner bag water pipe head is a female thread structure, and mid portion has a cylinder boss, on have first through hole; Water pipe is connected earlier in the inner bag water pipe head cylinder boss, the water inlet pipe and water outlet pipe joint is connected in the inner bag water pipe head more then, can be by this structure so that the water inlet pipe and water outlet pipe joint has the effect of anti-electrical network, can make water inlet pipe and water outlet pipe joint, inner bag water pipe head, water pipe fluid-tight engagement again, prevent to leak.
The specific embodiment
Embodiment: a kind of novel Inlet and outlet water structure of water heater, it comprises water inlet pipe and water outlet pipe joint 1, inner bag water pipe head 2, inner bag 3 and water pipe 4, to use direction to be benchmark, described inner bag water pipe head 2 lower ends (preferably) are provided with a boss 21, boss 21 (preferably center) but in be provided with first through hole 22 that proper feed pipe 4 plugs, described water pipe 4 lower ends are inserted in first through hole 22, described water inlet pipe and water outlet pipe joint 1 upper end is provided with second through hole 11 that just can supply boss 21 to plug, boss 21 location are inserted in second through hole 11, detachably fixedly connected with water inlet pipe and water outlet pipe joint 1 upper end in described inner bag water pipe head 2 lower ends, and water inlet pipe and water outlet pipe joint 1 lower end is provided with the third through-hole 12 that is connected with water pipe 4, water pipe is connected earlier on the inner bag water pipe head cylinder boss, the water inlet pipe and water outlet pipe joint is connected in the inner bag water pipe head more then, can be by this structure so that the water inlet pipe and water outlet pipe joint has the effect of anti-electrical network, can make the water inlet pipe and water outlet pipe joint again, the inner bag water pipe head, the water pipe fluid-tight engagement prevents to leak.
The lower end outer surface of described water pipe 4 is arranged with water pipe sleeve 5, and water pipe sleeve 5 is in first through hole 22.
Described inner bag water pipe head 2 lower ends with the mode of detachably fixedlying connected in water inlet pipe and water outlet pipe joint 1 upper end are: inner bag water pipe head 2 lower end medial surfaces are embedded with internal thread, and the outside, water inlet pipe and water outlet pipe joint 1 upper end is provided with the metal external thread with the internal thread coupling.
The junction of described inner bag water pipe head 2 lower ends and water inlet pipe and water outlet pipe joint 1 upper end is provided with first gasket seal 61.
Described water inlet pipe and water outlet pipe joint 1 is the integral plastics structure, and makes with metal external thread is one-body molded.
The internal diameter of described third through-hole 12 is less than the internal diameter of second through hole 11, and third through-hole 12 is in second through hole 11 fully, and described second and third through hole 11,12 intersections form shoulder, are provided with second gasket seal 6 between described water pipe 4 lower ends and described shoulder.
Described water pipe 4 is at least a kind of in cold water water pipe (water inlet pipe) and the hot water water pipe (outlet pipe).
