In order to ensure the insulation between heater and heated body in existing product, it is provided between heater and heated body Insulating materials, such as mica paper or ceramics.Cause heat transfer efficiency step-down, firing rate is slow, and the thermal efficiency is low, and thermal losses is big.

ZL201621126945.3 is disclosed《A kind of efficient heat radiating structure》, it includes the heating being connected with heating wire Body, the heater include core body, and the core body is heat-conducting metal, and the Surface coating of the core body has oxidation film layer；The electricity Heated filament is directly wound on the heater.

Efficient heat radiating structure provided by the utility model, layer oxide film is wrapped up on the surface of heater, is neither influenceed The heat transfer of heat carrier, while there is insulating properties again, further improve safety in utilization；Heating wire is directly wound in heater On, firing rate is fast, and the thermal efficiency is high, and heat loss is small.

But the heater processed complex degree is high, and need to use temperature control device temperature control, parts are more, cost It is high.

The content of the invention

Technical problem to be solved in the utility model is for a kind of convenient processing of present situation offer of prior art and dress Match somebody with somebody and the glue rifle heater of cost can be substantially reduced.

Technical scheme is used by the utility model solves above-mentioned technical problem：The glue rifle heater, including add Hot component, it is characterised in that the heating component includes PTC fever tablets, and two surfaces of the PTC fever tablets are connected to One conductive plate and the second conductive plate, first conductive plate connect positive pole pin, and second conductive plate connects negative pole pin；

First conductive plate is connected in the outlet port of glue stick protective case of glue rifle, and first conductive plate with There is the passage passed through for melten gel, the inner chamber of the nozzle of the passage connection glue rifle between the outlet port.

It is preferred that the area of the PTC fever tablets is less than the area of the outlet port, first conductive plate has fitting The first matrix and interval in the PTC fever tablets are connected at least two first legs on the first matrix periphery, Each first leg connects the periphery of the outlet port, and the gap between the first adjacent leg forms described passage.

To make melten gel to be maintained under the molten condition of constant temperature all the time before jetting nozzle, second conductive plate includes patch Closing the second matrix in the PTC fever tablets and externally protruding out in second matrix has the of the interior intracavitary that is plugged in the nozzle Two legs.By the design of the second pin, the constant temperature molten condition of melten gel has been effectively ensured.

As an improvement, the positive pole pin and the negative pole pin can stretch out respectively it is spacing in the protective case On lateral wall.The structure has fully ensured that the electrical safety of the heater, and the conveniently connection with power supply.

Compared with prior art, glue rifle heater provided by the present invention, has been overturned in the prior art outside glue stick The technology prejudice of heating is enclosed, heater is arranged in glue stick, heater is directly fitted in glue stick fusion, to glue stick Surface heat from level to level, melt, it is not necessary to carry out heat transfer in glue stick, heating is fast, and the melten gel after fusing is in glue stick Extruding under immediately enter the interior intracavitary of nozzle, heat loss is small, and the thermal efficiency is high, significantly improves the heated situation of glue stick and molten Change speed, energy conservation and consumption reduction effects are notable；And the present invention is simple in construction, and parts are few, and convenient processing and assembling, compared to existing There is technology to significantly reduce manufacturing cost, and can be temperature automatically controlled, temperature control effect is good.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing embodiment.

As shown in Figures 1 to 4, the glue rifle is included with heater：

Heating component, for heating glue stick, melten gel, including PTC fever tablets 1, two surfaces of PTC fever tablets 1 will be melt into The first conductive plate 2 and the second conductive plate 3 are connected to, the first conductive plate 2 connection positive pole pin 4, the connection of the second conductive plate 3 is negative Pole pin 5.

In the present embodiment, PTC fever tablets use circular configuration, and the area of PTC fever tablets 1 is less than the glue stick protective case of glue rifle The area of 6 outlet port 61, and positioned at the center position of outlet port 61.

First conductive plate 2, it is metallic plate, any one metal material of the prior art can be selected as needed, it is excellent Select copper with good conductivity；The first matrix 21 is connected to the first matrix of circle 21 being fitted in PTC fever tablets 1 and interval At least four first legs 22 on periphery, the other end of each first leg 22 are both connected to the outlet port 61 of protective case 6 On periphery, the gap between the first adjacent leg 22 forms the passage 62 passed through for melten gel.First in the present embodiment is conductive Plate 2 is integrally formed.

Second conductive plate 3, it is metallic plate, any one metal material of the prior art can be selected as needed, it is excellent Select copper with good conductivity；With the second matrix 31 being fitted in PTC fever tablets 1 and second that externally protrudes out in the second matrix 31 Pin 32；The second conductive plate 3 in the present embodiment is integrally formed.

Second leg 32 of the second conductive plate 3 is inserted into the inner chamber 71 of the nozzle 7 of glue rifle, with molten in nozzle to entering Glue heats, and is kept molten by melten gel, avoids the solidification of melten gel.

In the present embodiment, the outer peripheral edge of the first matrix 21 and the second matrix 31 overlaps with the periphery of PTC heating plates 1, so that Passage 62 connects the inner chamber 71 of nozzle.

In the present embodiment, the positive pole pin 4 for connecting positive source connects first leg in the first conductive plate 2 4；Negative pole pin 5 for connecting power cathode connects the second matrix 32 of the second conductive plate；Positive pole pin 4 and negative pole pin 5 Stretch out respectively spacing on the lateral wall of protective case 6.
