,包括燈管和燈絲,燈管兩端分別設有管套,管套上固定有電插片,燈絲安裝在燈管內,燈絲兩端延伸至兩端管套并與電插片相連,所述燈管內的燈絲呈盤繞狀,燈管內壁還設有燈絲限位凸起。本結構的電加熱管,為滿足大功率要求,將燈絲盤繞以減少燈管體積,即:一定燈管直徑下可縮小其燈管長度;其次,為防止燈絲在熱脹冷縮、或燈管豎向放置時,層與層之間的燈絲相互碰觸損壞燈管,而在燈管內壁上設置燈絲限位凸起,以卡頂盤繞狀的燈絲對應部位,使其相對于現有技術,功率相同的電加熱管其體積可以做得更小,或體積相同的電加熱管其功率做得更大;整個結構簡單、合理,電加熱管使用安全
The utility model discloses an electric heating pipe for electric heater, comprises a lamp and filament, lamp are respectively arranged on both ends of pipe, electric plug sleeve which is fixed, the filaments are arranged in the lamp tube, the two ends of the filament extending to the ends of pipe and electrical plug is connected with the lamp tube, the filament in a coil shape, tube the inner wall is provided with a filament limit bulge. The electric heating tube with the structure, to meet the power requirements of the filament wound tube, to reduce the volume, namely: a tube diameter can be reduced under the tube length; secondly, in order to prevent the filament in the thermal expansion and contraction, or tube vertically placed, between layer and layer filament touch each other damaged tube, and the filament spacing a bulge is arranged in the inner wall of the tube, the filament winding shaped top plate corresponding to the part of card, which compared with the prior art, the same power electric heating tube size can be made smaller, or the same volume of electric heating tube power bigger; the whole structure is simple, reasonable, safe use of the electric heating pipe
