Abstract

The utility model discloses a freezing and rupturing-resistance quartz electrothermal film heating pipe, comprising a pipe body made of quartz. The outer sidewall of the pipe body is provided with a conductive coating layer. Upper and lower ends of the conductive coating layer are provided with conducting strips connected with the conductive coating layer respectively. The pipe body is internally provided with a sealed container, wherein the outer wall of the sealed container is made of a soft material. When water in the pipe body is frozen and has a larger volume, the water extrudes the sidewall of the sealed container, so that the volume of the container is compressed, influences of increase in volume when the water is frozen on the pipe body are offset, and the pipe body is prevented from being frozen to rupture.

Description

The quartz electric heating film heating pipe that Anti-freezing breaks

Technical field

The utility model relates to the electric hot water tap technical field, especially relates to the quartz electric heating film heating pipe that a kind of Anti-freezing breaks.

Background technology

Referring to Fig. 1, quartz electric heating film heating pipe mainly comprises on the lateral wall of body 31 that quartz makes, body 31 and is provided with one deck conductive coating 3a, the up and down two ends of conductive coating 3a are respectively arranged with the conducting strip 32 that links to each other with conductive coating, during use, the up and down two ends of conductive coating 3a connect respectively live wire and zero line, connect with after-current by conductive coating 3a, so that conductive coating 3a heating, the heating tube wall when current flow through in the body 31, is heated by tube wall.

Generally all be water-filled in the body, when winter temperature was lower, water can freeze in the body, and at this time the volume of water will expand in the body, might be split up body, therefore is necessary to be changed.

Summary of the invention

The utility model is for deficiency of the prior art, the quartz electric heating film heating pipe that provides a kind of Anti-freezing to break, and preventing effectively that body is freezing breaks.

For solving the problems of the technologies described above, the utility model is solved by following technical proposals: the quartz electric heating film heating pipe that Anti-freezing breaks, comprise the body that quartz is made, be provided with one deck conductive coating on the lateral wall of body, the up and down two ends of conductive coating are respectively arranged with the conducting strip that links to each other with conductive coating, are provided with the closed container that outer wall is made by flexible material in the described body.When the water freezing volume in the body becomes large, the sidewall of water extruding closed container, so that container volume is compressed, the impact of the body that volume increases when offsetting water freezing, preventing that body is freezing breaks.

In the technique scheme, the structure of concrete a kind of container is, described container comprises rubber hose, and the two ends of described rubber hose are provided with stopper.

In the technique scheme, preferred, be provided with muscle on the sidewall of described rubber hose, the inwall close contact of described muscle and described body limits the radial position of rubber hose in body.

In the technique scheme, preferably, the up and down two ends of described body are provided with pipe box, described pipe box one end is enclosed within on the described body, form the stop part that inwardly stretches out on the other end of described pipe box, form outwardly directed lug boss on the described stopper, when described container towards pipe during extracorporeal movement, described stop part props up described lug boss, prevents that container from running out of in the body.

The beneficial effects of the utility model are: when the water freezing volume in the body becomes large, and the sidewall of water extruding closed container, so that container volume is compressed, the impact of the body that volume increases when offsetting water freezing, preventing that body is freezing breaks.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail: referring to Fig. 2 to Fig. 3, the quartz electric heating film heating pipe that Anti-freezing breaks, comprise on the lateral wall of body 31 that quartz makes, body 31 and scribble one deck conductive coating 3a, the up and down two ends of conductive coating 3a are respectively arranged with the conducting strip 32 that links to each other with conductive coating 3a, are provided with the closed container 33 that outer wall is made by flexible material in the described body 31.Container 33 comprises rubber hose 331, and the two ends of rubber hose 331 are provided with stopper 333, and stopper 333 clogs the two ends of rubber hose 331, forms a closed cavity.Be provided with muscle 332 on the sidewall of rubber hose 331, the inwall close contact of described muscle 332 and described body 31.

The up and down two ends of body 31 are provided with pipe box 34, pipe box 34 1 ends are enclosed within on the body 31, and the stop part 341 that inwardly stretches out is arranged on the other end of pipe box 34, form outwardly directed lug boss 334 on the stopper 333, when container 33 during towards body 31 outer motion, stop part 341 props up lug boss 334.When the water freezing volume in the body 31 became large, water pushed the sidewall of airtight rubber hose 331, so that container 33 volumes are compressed, the impact of the body 31 that volume increases when offsetting water freezing prevents body 31 freezing breaking.
