Abstract
The utility model discloses a heating device of melt glue gun PTC, wherein two conductive metal pieces combined with PTC ceramic heating element are inserted in an outer ceramic cover which one end is closed, ceramic powder slurry is filled between the outer ceramic cover and PTC ceramic heating element and the two conductive metal pieces, and two power lead wires connected with the two conductive metal pieces are separately sealed and fixed at the port of the outer ceramic cover. The utility model not only retains good thermal performance and automatic constant heating and other characteristics of the PTC ceramic heating element but also overcomes the disadvantages of the element with low insulation and being broken down by humidity.
Description
Technical field
The utility model relates to a kind of PTC electro-heat equipment that is used for melting glue gun.
Background technology
Bonding between the object in fields such as melting glue gun is widely used in building, fitting-out work, electronic apparatus, toy, furniture manufacturing.The heating structure of existing melting glue gun is to clip the PTC ceramic heating element by two sheet metals, they is wrapped as insulating materials with polyimide film again, and the separation heater element contacts with metal melten gel shell.The PTC ceramic heating element is made by a kind of ptc characteristics material, utilize its ptc characteristics to carry out temperature control and constant temperature, its principle be heater element when room temperature state, the heater resistance value is very low, electric current is big during energising, be rapidly heated, along with temperature rises, the heater resistance value is also followed rising, and electric current reduces, power descends, and enters saturated heated condition behind the certain hour.This thermostatic characteristics makes the requirement that has reduced in the circuit the temperature control part, has reduced cost.But, because polyimides is a kind of plastics of poor thermal conductivity, is unfavorable for the heat transmission, thereby influences the thermal efficiency, in the temperature long-term work more than 200 ℃, accelerated ageing easily, embrittlement is rotten, reduces insulativity, makes the electric property variation.Use Kapton wrapping heater element, poor sealing performance, and PTC ceramic heating element material has certain moisture absorption, the puncture of making moist easily in wet weather influences work.The maximum operation (service) temperature of polyimides is 280 ℃, so the operating temperature of PTC ceramic heating element can not select too highly, thereby influences heating property and melten gel performance.Therefore, this PTC ceramic heating element with the Kapton wrapping, indexs such as its safety in utilization, reliability, life-span are relatively poor, add the various factors that assembling connects, and cause electric property poor, and the scope of application is restricted.
Summary of the invention
The purpose of this utility model is can keep the good heating property of PTC ceramic heating element to overcome existing heater element insulativity again low, the melting glue gun PTC electro-heat equipment of drawbacks such as moisture-sensitive puncture in order to provide a kind of.
Main technical schemes of the present utility model is: two conducting metal spares clip the PTC ceramic heating element and insert in the outer insulator of sealing at one end, be full of porcelain powder slurry between outer insulator and PTC ceramic heating element, two conducting metal spares, outer insulator port sealing and fixing has two power supply lead wires that are connected with two conductive metal sheets respectively.
The utility model utilizes external ceramic tube, porcelain powder slurry thoroughly to completely cut off PTC ceramic heating element, conductive metal sheet and extraneous contacting, and has also just solved the drawback that existing heater element moisture-sensitive punctures.And the utility model has improved the heating efficiency of PTC ceramic heating element, its insulaion resistance is greater than 150M Ω, electrical strength reaches more than the 3750V, and static capacity is less than 20P, and leakage current is less than 1 μ A, and have simple in structure, easy to assembly, voltage range wide (100-240V all can), the flames of anger, characteristics such as constant temperature is regulated power automatically, and energy-saving effect is obvious, safe and reliable.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of an embodiment of the utility model;
Fig. 2 is that Fig. 1 is installed in the structural representation on the melting glue gun.
The specific embodiment
As shown in Figure 1, two conducting metal spares 4 clip in the outer insulator 2 of PTC ceramic heating element 3 slotting sealings at one end in the present embodiment, be full of porcelain powder slurry 5 between outer insulator 2 and PTC ceramic heating element 3, two conducting metal spares 4, form by the sealing sintering, outer insulator 2 port sealing and fixing have two power supply lead wires 1 that are connected with two conductive metal sheets 4 respectively.
As shown in Figure 2, after the utility model is connected power supply, the heating of PTC ceramic heating element, heat passes to the heating shell 6 of melting glue gun through outer insulator 2, heating shell 6 passes to the PUR of melting glue gun heating shell inner chamber with temperature, and the fluid that has melted flows out through glue discharging mouth by the plastic emitting passage.
