Specific embodiment
Embodiment 1
A kind of hot type pipeline of the present embodiment, with reference to Fig. 1, including tube body 2, plug 4 and heater strip 6,2 outer wall of tube body is provided with
Rib 5, between rib 5 and tube body 2 winding be provided with heater strip 6, which connect with plug 4, plug 4 it is another
End is connect with power supply, and heater strip 6 is made to be formed between rib 5 and tube body 2 and is closed heating circuit.
With reference to Fig. 4, above-mentioned pipeline is integrally formed on molding machine 3, sheet material a, muscle material b and heating silk material c send respectively into
On type machine 3, sheet material a is heated to after melting stretchable state, is squeezed out by the sheet die 11 of sheet extruder 1, in molding machine 3
Upper to form hollow tube body 2, heating silk material c is wrapped between tube body 2 and rib 5, after molding, in tube body 2 as starting
Plug 4 is embedded on the one end at end, injection molding is to complete the processing of entire pipeline.
In above process, it is heated to after melting stretchable state with reference to Fig. 5, muscle material b, is squeezed out, added by rib mouth mold 71
Heated filament material c is sent out by the heater strip outlet 72 on 71 top of rib mouth mold, and heating silk material c rides over what is rotated always together with muscle material b
On molding machine 3, after machine 3 to be formed rotates several seconds, butt strip material a, after three hangs together, under 3 turning effort of molding machine directly
Form above-mentioned hot type pipeline.
In the present embodiment, heating silk material c respectively becomes the stretchable state of melting using enameled wire, sheet material a, muscle material b,
It was overlapped on molding machine 3 by 2-10 seconds time, since the rotary force of molding machine 3 takes sheet material a, muscle material b, heating silk material c
Connect rear self-assembling formation heater strip pipeline.
To realize further use demand, it is as follows that said program can also continue to increase setting：The two of the tube body 2
Inlet porting end 22 and the port of export 23, arrival end 22 are an integral molding structure with tube body 2, the port of export 23 and tube body 2 respectively at end.
To realize further use demand, it is as follows that said program can also continue to increase setting：Plug 4 and heater strip
6 connecting pin is embedded in advance in tube body 2 or arrival end 22, uses one-time formed flush type injection molding process, efficient, can
By property height.
To realize further use demand, heater strip can be used following three kinds of modes and set：
First way：With reference to Fig. 2, heater strip 6 is located at the intersection of tube body 2 and rib 5.By heater strip 6 be set to tube body 2 with
The intersection of rib 5 with extraneous isolation completely, can not only be evenly heated the gas to circulate in the tube chamber 21 of tube body 2,
It winds setting, and cooperation tube body 2 can also strengthen the intensity of tube body 2, and 2 intensity of tube body caused by making up long-term be heated adds up to subtract
It is weak.
The second way：With reference to Fig. 3, heater strip 6 is located in rib 5.Heater strip 6 is set in rib 5, processing is cleverer
It is living, it is also possible to ensure being evenly heated for gas in tube body 1.
The third mode：Heater strip 6 is distributed in tube body 2 and 5 intersection of rib and rib 5.Heater strip 6 is distributed
In in intersection and rib 5, not with air and moisture, avoid leaking electricity and corrode generation, and the appearance being not take up in tube chamber 21
Product, 21 interior air-flow resistance of tube chamber are small.
To realize better using effect, said program can also be added as follows：
With reference to Fig. 1-Fig. 3, heater strip 6 is provided with two groups, is referred to as heater strip 1, heater strip 2 62, and heater strip 1 adds
Heated filament 2 62 is mutually parallel during the winding process not to be contacted.The setting of two groups of heater strips ensures the stability of heating, and avoid
The mist generated when heating tube wall.
It is furthermore preferred that the end of heater strip 1 and 2 62 terminal tandem of heater strip, and the beginning of heater strip 1 is with adding
The beginning of heated filament 2 62 is connect with electrical socket 4.
Hot type pipeline provided herein, heater strip 6 are embedded in the form of winding between tube wall and rib 5（Packet
It includes but is not limited to the two ways in tube body 2 and 5 intersection of rib and rib 5 of heater strip 6）, heater strip 6 not with air and steam
Contact avoids leaking electricity and corrodes generation；21 volume of tube chamber is not take up, gas-flow resistance is small；Because 6 uniform winding of heater strip is in tube body 2
Between rib 5, heater strip 6 is arranged uniformly, homogeneous heating, because heating tube wall is so mist will not be generated, moreover it is possible to be formed in pipe
With isolation layer outside pipe, it is particularly suitable for having used the mechanical ventilation mode of heating humidifier；Pipeline inner wall is smooth, gas-flow resistance
It is small.
