The hidden danger of leaking of the prior art mainly concentrates on the first sealing ring position, because this first sealing ring is O shape circle, although O shape circle has sealing effectiveness, after assembling, due to less with the contact area of water inlet pipe tube head or outlet pipe tube head inwall, be similar to line contact between the two, once contact-making surface has at all damaged, the just easy seepage of moisture, thus cause leaking, as long as therefore manage to increase the contact area of the first sealing ring, can effectively reduce drainage, reduce the hidden danger of leaking.
The technical scheme that the utility model solves its technical problem employing is: it comprises water tank and anti-electric wall, water tank is provided with water inlet pipe tube head, outlet pipe tube head, the link position of the connector of anti-electric wall and water inlet pipe tube head or outlet pipe tube head is equipped with separates the first sealing ring and the second sealing ring arranging, wherein the first sealing ring and the second sealing ring are plain washer, and the first sealing ring and the second sealing ring are all fixed in end face seal mode.
Preferably, outer surface or inner surface on water inlet pipe tube head or outlet pipe tube head are provided with positioning step, the upper and lower end face of the first sealing ring respectively with the end face end face seal of positioning step, anti-electric wall connector.Positioning step is set and can not only provides seal face for the first sealing ring, and can reduce the thickness of water inlet pipe tube head or outlet pipe tube head integral body, effectively reduce the material cost of water inlet pipe tube head or outlet pipe tube head, the end face of anti-electric wall connector of take contributes to simplify the structure of anti-electric wall connector as seal face, avoid additionally manufacturing the end face for sealing, reduce the production cost of anti-electric wall.
Further, for making material cost and the mechanical performance of water inlet pipe tube head, outlet pipe tube head be controlled at optimum range, the water inlet pipe tube head that positioning step is positioned at or the outer surface on outlet pipe tube head and width are 1 ~ 4mm, now, because the face area of positioning step is less than normal, for ensureing the effect of end face seal, between positioning step and the first sealing ring, be provided with supporting pad, supporting pad packs into water inlet pipe tube head or outlet pipe tube head, and supporting pad and the first sealing ring end face seal.
Further, the outside of supporting pad is provided with the flanging of restriction the first sealing ring outside dilatancy while being squeezed.
Again further, the material of described supporting pad is nylon, nylon glass, copper, iron, steel, stainless steel, aluminum or aluminum alloy, the longitudinal section of supporting pad is the Contraband font falling, and the top of supporting pad is provided with the through hole that supplies water inlet pipe tube head or outlet pipe tube head to pass, and the first sealing ring is enclosed in supporting pad.The hardness of supporting pad is greater than the hardness of the first sealing ring; And first sealing ring covered, can prevent the first sealing ring excessively compressed after distortion outwards expand.
Preferably, water inlet pipe tube head or outlet pipe tube head are plastic cement material, the upper and lower end face of the second sealing ring respectively with the root end face end face seal of the bottom surface of water inlet pipe tube head or outlet pipe tube head, anti-electric wall connector, contribute to simplified structure, avoid additionally manufacturing the end face for sealing, reduce production costs.
Preferably, water inlet pipe tube head or outlet pipe tube head are metal material, water inlet pipe tube head or outlet pipe tube head inner sleeve have gum cover pipe, the mouth of pipe of gum cover pipe is provided with flange, flange is close to the bottom surface of water inlet pipe tube head or outlet pipe tube head, the upper and lower end face of the second sealing ring respectively with the root end face end face seal of flange bottom surface, anti-electric wall connector.
The utility model is compared produced beneficial effect with background technology:
1, because the utility model adopts two plain washers and fixes in the mode of end face seal, by improving the sealing area of sealing ring, further improve the sealing that electric heater is connected with anti-electric wall, effectively reduced drainage appearance.
