Abstract
The utility model relates to a thermal element of electric heating hot melt gum gun, which discloses an outboard porcelain pipe with a sealed end. The inner of outboard porcelain pipe is installed an inner porcelain stick bound with electric heating wire. Porcelain cement slurry is filled between the inner porcelain pipe and outboard porcelain pipe, and the port point of the outboard porcelain pipe is fixed a sealing annular tube leading out the blaster fuse. The utility model has a high electric strength, a small electrostatic capacity, a small bleeder current and has no hammering action to circuit. Besides, the utility model is free from the effect of higher temperature range and wet weather effect so that it can be widely used as well as the electric heating element has a high thermal efficiency, simple structure and can be easily installed.
Description
The utility model relates to a kind of electrical heating element, especially for the electrical heating element of melting glue gun.
At present, melting glue gun is widely used in architectural engineering, fitting-out work, and electronic apparatus, furniture manufacturing industries etc. for the bonding between the object has fixedly played positive role, have been subjected to user's welcome.The heating of existing electric heating hot melt gum gun adopts the PTC ceramic heating element more, the PTC heater element is that a kind of ptc characteristics material is formed, utilize its ptc characteristics to carry out temperature control and constant temperature, its principle is that heater element is when room temperature state, the heater resistance value is very low, big electric current passes through during energising, be rapidly heated, along with temperature rises, the heater resistance value is also followed rising, and electric current reduces, and power descends, enter saturated heated condition behind the certain hour, this constant temperature form temperature-controlled precision is low, discreteness is big.And the PTC ceramic heating element can not be operated in higher warm area, and operating power is subjected to the influence of its inherent characteristic, can not do too much; Add the reason on the assembly structure, cause electric property poor, insulativity is low; Because the heater material has moisture absorption, in the wet weather puncture of making moist easily, so the scope of application is restricted.
The purpose of this utility model provides a kind of heater element of electric heating hot melt gum gun, its insulaion resistance, electrical strength height, static capacity is little, leakage current is little, and circuit is not had percussion, not influenced by higher warm area, wet weather, the scope of application is wide, and electrical heating element thermal efficiency height, simple in structure, easy to assembly.
Technical solution of the present utility model is the external ceramic tube that end sealing is arranged, and the interior bar magnet that is twining heating wire is arranged in that external ceramic tube is built-in, and being full of between interior porcelain rod and external ceramic tube has porcelain powder slurry, at leaded sleeve pipe of external ceramic tube port sealing and fixing and lead-out wire.
The porcelain rod is solid barred body in the above, or hollow barred body.
After the utility model utilization lead-in wire was connected power supply, electric current promptly generated heat through heating wire, and heat is passed to the heating shell of melting glue gun by external ceramic tube, the heating shell is passed to the PUR of melting glue gun inner chamber with temperature, and the fluid glue that has melted flows out through glue discharging mouth by the plastic emitting passage.Insulaion resistance of the present utility model is greater than 150M, and electrical strength can reach 4000V to 5000V, and static capacity is less than 20P, and leakage current does not have percussion less than 1 μ A to circuit, and therefore safe and reliable, the utility model is simple in structure, processing, easy to assembly.The utility model can also be in external ceramic tube the end and in the excellent end of porcelain device thermocouple, utilize electronic temperature control circuit to carry out accurate temperature controlling, its temperature-controlled precision is in ± 5 ℃ of scopes.
The utility model has the advantages that insulaion resistance, electrical strength height, static capacity is little, and leakage current is little, and circuit is not had percussion, not influenced by higher warm area, wet weather, and the scope of application is wide, and electrical heating element thermal efficiency height is simple in structure, and is easy to assembly.
Below in conjunction with accompanying drawing embodiment of the present utility model is described:
Fig. 1 organigram of the present utility model;
The position of Fig. 2 user mode of the present utility model, organigram.
According to shown in Figure 1, the utility model has the external ceramic tube 3 of end sealing, the interior porcelain rod 4 that is twining heating wire 5 is arranged in that external ceramic tube is built-in, and interior porcelain rod 4 is full of with 3 of external ceramic tubes porcelain powder slurry 7 is arranged, and has in external ceramic tube port sealing and fixing and draws 1 the sleeve pipe 2 of going between.
The utility model can also be in external ceramic tube 3 end and in install thermocouple 6 between porcelain rod 4 ends.
According to shown in Figure 2, the utility model is to insert in the heating core chamber of melting glue gun heating shell 8 when using.
