Abstract
The utility model relates to a heating tube used for electric heater, bath heater, and heating device, comprising a transparent tube body, a heater arranged in the tube body, and an electrode in electric connection with the two ends of the heater. Two gas in-out ports of the tube body are arranged on the two ends of the tube body. The electrode threads out from the gas in-out ports and seals the gas in-out ports. The utility model which has simple and reasonable structure and design, firstly pumps vacuum from the air in-out ports on the two ends, secondly fills in protective gas, and finally flattens and seals the gas in-out ports; the pass percent of the product is greatly increased; the material is saved; the service life of the heating tube is prolonged; the external shape is more beautiful and can be bent into various shapes.
Description
Technical field
The utility model relates to a kind of heat-generating pipe that electric heater, super bath and heater use that is used for.
Background technology
The heat-generating pipe that existing heater is used all is to be made of transparent tube body, heater and electrode; the middle part of body is provided with an air inlet/outlet, and the effect of this air inlet/outlet is earlier body inside to be vacuumized, and charges into protective gas again; the existence of this air inlet/outlet makes the body frangibility, and easily gas leakage.
Summary of the invention
Therefore, the purpose of this utility model is to provide a kind of bulk strength of body that makes to be improved and the better heat-generating pipe of sealing property.
The purpose of this utility model is to realize like this.
A kind of heat-generating pipe comprises transparent tube body, is located at heater in the body and the electrode that is electrically connected with the heater two ends, and the air inlet/outlet of described body is located at the two ends of body, and electrode passes from air inlet/outlet, again the air inlet/outlet hermetic seal.
Above-mentioned purpose also can be done further perfect by following technical proposals.
Described hermetic seal is that the body at air inlet/outlet place is flattened.The outer electrode of electrode in the described body and body passes through the molybdenum sheet transition, and molybdenum sheet is embedded in flattening place of body.Described body can be linearly, semicircle shape, pear shape.
The utility model structural design advantages of simple; air inlet/outlet from two ends vacuumizes earlier; charge into protective gas again; at last air inlet/outlet is flattened sealing; improve the qualification rate of product greatly; also economical with materials, prolonged useful life of heat-generating pipe, the profile of heat-generating pipe is more attractive in appearance, can curve different shape.
