Description

Electric heating element of the binding post in the double casing of same one end

Technical field

It the utility model is related to electric heater, central heater, solar water heater, air-source water heater, electric boiler, drink Water dispenser, boiler, small kitchen treasured etc., hot-water heating system is immersed in the electric heating element in water, relates generally to binding post in same one end The electric heating element of double casing.

Background technology

Patent application 201611043687.2,201621265160.X and 201611000628.7,201621222169.2 The electric heating element structure of double casing is proposed, by practice, heating wire is continuous firing in blind hole one end, or has tie point After energization work, temperature is too high herein, causes heating wire to blow or inner tube glass breakage, and it is both ends outlet also to have inner tube, After the connection of blind hole one end, the structure that is integrally constituted, but blow-by, after outer layer breakage, this end of inner tube can intake, and produce leakage Electricity, human body injury accident may be caused, while manufacturing cost is high, popularization is restricted.

The content of the invention

The purpose of this utility model is that the product involved by above-mentioned patent application is improved, and overcomes existing lack Fall into.

Technical measures of the present utility model are the electric heating elements 11 of double casing, by hole on installation connection component 13 and the part Installation shell 8 and the electrothermal tube 9 of the interior installation of shell are formed in 18, described to be made using double casing, are in shell 8, there is one Root or more electrothermal tube 9, it is in non-metallic pipe 5（Or the shell of internal layer）Built with heating wire 3, heating wire 3 in its single pipe Both ends installation eduction rod 1, the connector 14 in blind hole one end by heating wire, two eduction rods of the other end is existed after connection Same one end, if only with an electrothermal tube 9 when, blind hole one end eduction rod 1 by non-metallic insulation pipe 10, drawing from the other end Go out（Fig. 3）；Shell 8 is installed in the hole 18 of installation connecting element 13, and is connected with fluid sealant 2, it is ensured that Vent does not leak pressure-bearing 0.12MP.

Interior electrothermal tube 9 is constructed as below：

1. being that heating wire is carbon fiber or metal in non-metallic pipe 5, vacuumized in it or inject non-combustible, not combustion-supporting gas Body or inert gas（Fig. 1, Fig. 3）；

2. be heating alloy in non-metallic pipe 5, heating wire by the nonmetallic protruded tube of plug 6 outside, while both ends glue Sealing, and make to form negative pressure in pipe or communicated with the external world（Fig. 2）；

Electrothermal tube 9 constructed above loads in blind hole one end in shell 8, will be exposed with fluid sealant 2 and nonmetallic lid 15 Heating wire, eduction rod and connector 14 are fully wrapped around firmly, and ensure this end being immersed in water, and voltage is 1.35 times, at full capacity Work more than 48 hours, electrical property meets standard.

3. non-metallic pipe 5 is blind hole pipe, using the heating alloy of continuous firing, and turns back and make two eduction rods same End, close to blind hole one end, it is impossible to there is the coil of coiling（It should be straight line）, cold end 17 is formed, and with the non-gold of high-temperature insulation Category plate 7 separates the heating wire turned back；There is nonmetallic plug 6 in unlimited one end, the outer end fluid sealant 2 of plug seals, blind hole Negative pressure or to be communicated with the external world in pipe（Fig. 4）.

Brief description of the drawings

Fig. 1 to Fig. 3 is interior electrothermal tube structure figure；

Fig. 4 is the structure chart that non-metallic pipe 5 is blind hole；

Fig. 5 Fig. 8 is the structure chart of the electric heating element of double casing；

Fig. 6 is fully wrapped around firmly in blind hole one end, and Fig. 7 heating wire is isolated with insulation board；

Embodiment

In accompanying drawing, binding post or eduction rod 1, fluid sealant 2, heating wire 3, air 4, non-metallic pipe 5, nonmetallic plug 6th, high-temperature insulation non-metal board 7, nonmetallic or metal blind hole pipe（That is shell）8th, electrothermal tube 9, non-metallic insulation pipe 10, bilayer Shell electric heating element 11, tracheae 12, installation connection component 13, the connector 14 of heating wire, the keeper 16 of nonmetallic lid 15, cold end 17th, housing mounting holes 18.

Fig. 1, Fig. 3 are the built-in heating wire 3 of housing non-metallic pipe 5 of electrothermal tube 9, are the carbon fiber vacuumized in Fig. 1 and Fig. 3 Pipe or halide torch, Fig. 3 are only to use heating alloy with the typical structure of 1 pipe, Fig. 2, be pumped into pipe negative pressure or with extraneous phase It is logical；Fig. 4 non-metallic pipes 5 are blind hole pipe, heating wire are turned back with high-temperature insulation non-metal board 7 in it, the heating wire that will be turned back Isolated insulation, and the small cold end 17 of caloric value is fabricated in blind hole one end.

Interior electrothermal tube 9 in Fig. 1 to Fig. 3, Fig. 5, Fig. 6, loading blind hole one end of shell 8, with fluid sealant 2 and nonmetallic lid 15, exposed heating wire, eduction rod and connector 14 is fully wrapped around firmly, it is ensured that this is immersed in water, voltage is 1.35 times, Operate at full capacity more than 48 hours, electrical property meets the requirements.

Fig. 4 and Fig. 7, Fig. 8 are that non-metallic pipe 5 is blind hole pipe, and heating wire high-temperature insulation non-metal board 7 will turn back in pipe Heating wire isolated insulation, and the small cold end 17 of caloric value is fabricated in blind hole one end.
