Specific embodiment

In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new Embodiment.

A kind of electrothermal film heating pipe being easily installed as shown in Figure 1, including tube body 1, seal nipple 2 and lead 3, make close Sealing joint 2 and tube body 1 are tightly connected, and lead 3 is arranged on seal nipple 2.Preferably implement as a kind of in the present embodiment Mode, the electrothermal film heating pipe further include fixing pipe 4, Electric radiant Heating Film 5 and electrode 6, and fixing pipe 4 is built in tube body 1, the fixing pipe It is detachably connected between 4 and seal nipple 2, is attached at Electric radiant Heating Film 5 on the outer wall of fixing pipe 4, electrode 6 is attached at Electric radiant Heating Film 5 Above and around the circumferential directions of fixing pipe 4, the lead 3 and electrode 6 it is electrically connected.

As shown in Figure 1, the present embodiment is equipped with fixing pipe 4, and then Electric radiant Heating Film 5 can be attached in fixing pipe 4 in advance, electricity Pole 6 is attached in Electric radiant Heating Film 5, and electrode 6 and lead 3 are electrically connected, and then fixing pipe 4 is put into tube body 1 again, fixing pipe 4 with It is detachably connected between seal nipple 2, is arranged in lead 3 on seal nipple 2, make seal nipple 2 and the airtight company of tube body 1 It connects, just can complete the installment work of electrothermal film heating pipe, the structure of the electrothermal film heating pipe is relatively simple, installation and removal equal ten It is convenient to divide, so that operation difficulty reduces, processing technology is relatively simple, can reduce production cost, improves production efficiency.

It should be noted that as shown in Figure 1, being sticked including directly or indirectly two ways for the present embodiment meaning, i.e., electric Pole 6 can directly be contacted with Electric radiant Heating Film 5, be directly attached in Electric radiant Heating Film 5, as electrode 6 can be sticked by the fixation of the method for spraying In in Electric radiant Heating Film 5；Indirect mode can be attached in Electric radiant Heating Film 5 indirectly by adhesive sticker, can also pass through other fitting sides The choice specimen of calligraphy is set in Electric radiant Heating Film 5.Tube body 1 in this implementation can be made of glass material, be also possible to made of metal material, It can also be made of other materials.

It is emphasized that is, the internal diameter of fixing pipe 4 is than tube body 1 as shown in Figure 1, fixing pipe 4 is built in tube body 1 Internal diameter is small.So that the technique of processing is relatively simple, it can reduce human cost and material cost, Electric radiant Heating Film 5 can be saved With the material of electrode 6.

Specifically, as shown in Figure 1, the quantity of electrode 6 is two, two electrodes 6 are attached at the both ends of fixing pipe 4 respectively, Two electrodes 6 are parallel to each other, help to make conductive uniform.

It is noted that making electrode 6 be coated in Electric radiant Heating Film as shown in Figure 1, electrode 6 in the present embodiment is silver electrode 6 On 5, silver paste is coated in Electric radiant Heating Film 5 when specific implementation.Using the fixed form of wall-attaching type, so that electrode 6 being capable of jail It is fixed in Electric radiant Heating Film 5, prevents its movement from walking.

Further, as shown in Figure 1, fixing pipe 4 in the present embodiment is hollow glass tube, help to save material at This, can have thermally conductive function using glass tube, and material cost is lower, lighter in weight.

More specifically, as shown in Figure 1-3, seal nipple 2 include sleeve 7 and silica gel sealing ring 8, sleeve 7 and tube body 1 are airtight It connects, 8 hermetic sealing tube body 1 of silica gel sealing ring, offers through-hole 12 on silica gel sealing ring 8, lead 3 is arranged in through-hole 12, silicon Glue sealing ring 8 and fixing pipe 4 are clamped, and are also provided with the gas outlet being connected to inside tube body 1 on silica gel sealing ring 8.

It is understood that as shown in Figure 1-3, on the one hand the air-tight connection of seal nipple 2 and tube body 1 needs preferable gas On the other hand close property should also have preferable bonding strength；Based on this, the air-tight connection of tube body 1 and seal nipple 2 is improved Property, including but not limited to following technical approach can be taken:

1) silica gel sealing ring 8 forms tube body 1 and coats, to reduce the probability that tube body 1 falls off from seal nipple 2；

2) it can be equipped with internal screw thread on the inner wall of sleeve 7, make to be threadedly coupled between sleeve 7 and tube body 1, to increase sleeve 7 with the bonding strength of tube body 1.

Silica gel due to electrothermal film heating pipe heating rate with higher and higher heating power, in the present embodiment One or more than one gas outlet are offered on sealing ring 8, in use, can effectively be buffered Electric radiant Heating Film 5 and instantaneously be risen Huge pressure difference inside and outside tube body 1 caused by under warm or high hydraulic condition, will largely reduce booster rate, so that the electricity Hotting mask heating tube has longer service life, could be applicable to the higher region of hydraulic pressure, greatly improves heated by electrothermal film The security performance of pipe reduces the maintenance cost in later period.The gas outlet can be clear opening, and clear opening facilitates processing, when use Gas can freely pipe inner tube be connected to outside；Threaded hole can also be further arranged to, threaded hole can be to electrical in tube body 1 Element forms protection, and dust, moisture etc. is prevented to be directly entered tube body 1.

Further, as shown in Figure 1,3, auxiliary section 9 is formed on silica gel sealing ring 8, the both ends of fixing pipe 4 are equipped with Opening 10 makes 10 clamping of auxiliary section 9 and opening, so that fixing pipe 4 is capable of fixing on silica gel sealing ring 8, the both ends of lead 3 are divided It is not fixed on silica gel sealing ring 8 and fixing pipe 4, so that the mounting structure of lead 3 is relatively stable.

As shown in figure 3, in order to keep silica gel sealing ring 8 and the connection structure of fixing pipe 4 more stable, more preferably embodiment It is to be equipped with sealing bar on auxiliary section 9, realizes auxiliary section 9 and opening 10 and be tightly connected, on the inner wall of silica gel sealing ring 8 There is sealing bar, realizes silica gel sealing ring 8 and tube body 1 and be tightly connected, so as to improve between seal nipple 2 and tube body 1 Air-tightness.

In addition, conducting ring 11 is sheathed in fixing pipe 4 as shown in Figure 1, the electrothermal film heating pipe further includes conducting ring 11, Lead 3 is connect by conducting ring 11 with fixing pipe 4, and lead 3 and conducting ring 11 are electrically connected, and conducting ring 11 electrically connects with electrode 6 It connects, one end of lead 3 is connected with conducting wire, and conducting wire with external power for connecting.External power work, electric current are delivered to electricity through lead 3 Pole 6, so that 5 heating power of Electric radiant Heating Film, the temperature of fixing pipe 4 rises, and heat passes to tube body 1, heated by electrothermal film by air Pipe is achieved the function of its heating.

It in the present embodiment, is two as shown in Figure 1, the quantity of lead 3 is equal with the quantity of electrode 6, two leads 3 Parallel to each other, two leads 3 are drawn in parallel, help to make to be not easy to collide between two leads 3, lead 3 and tube body 1, so that electric The safety of hotting mask heating tube is higher.

Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to In the utility model range claimed.
