Description
Technical Field
The utility model relates to an electric welding heating tube technical field especially relates to a pottery heating tube.
Background
The electric soldering iron is a necessary tool for electronic manufacturing and electric appliance maintenance, mainly used for welding elements and leads, can be divided into an internal heating type electric soldering iron and an external heating type electric soldering iron according to mechanical structures, can be divided into a non-tin-suction electric soldering iron and a tin-suction type electric soldering iron according to functions, and can be divided into a high-power electric soldering iron and a low-power electric soldering iron according to different purposes; the heating pipe for the existing external heating type electric soldering iron is a stainless steel heating pipe, and the specific method is that a heating wire (the heating wire can also be called as a resistance wire) is placed in a stainless steel pipe, and magnesium powder is filled in the stainless steel pipe; the drawbacks of such a process are: the heating wire is easy to age and short in service life, and on the other hand, when the surface temperature of the heating pipe is 700 ℃ or above, the resistance of the heating pipe is reduced quickly, and electric leakage is easy to generate.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a ceramic heating tube of long service life, stable performance difficult electric leakage to solve the problem that proposes in the background art.
In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
the utility model provides a ceramic heating tube, includes the ceramic body of cylinder type, fixed resistance wire and the pin of setting in the ceramic body, the pin has two, and respectively with the both ends electric connection of resistance wire, the heat conduction hole has been seted up to the other end of ceramic body, the fixed one end that sets up at ceramic body keeps away from the heat conduction hole of one end of pin.
Further, the resistance wires are uniformly distributed in the ceramic body.
Furthermore, gaps are symmetrically formed in one end, close to the pins, of the ceramic body.
Furthermore, a fixing groove is longitudinally formed in the cylindrical surface of the ceramic body.
Further, still include the welding piece, the fixed one end that sets up at ceramic body and be close to the pin of welding piece, the fixed welding of pin is on the welding piece.
Furthermore, one end of the ceramic body close to the heat conduction hole is provided with a step around the circumference.
The utility model has the advantages that: the utility model discloses a set up the resistance wire fixedly inside ceramic body, set up the heat conduction hole at ceramic body's the other end, after the resistance wire generates heat, the heat can realize the transmission simultaneously to ceramic body's inside and outside, with prior art put into the heater in the stainless steel pipe, fill the magnesium powder simultaneously and compare, this real neotype resistance wire seals inside ceramic body, has slowed down oxidation and ageing by a wide margin to life has been prolonged; on the other hand, the utility model discloses a ceramic material, make full use of pottery high temperature resistant, corrosion-resistant and the high and stable characteristic of resistance, when heating pipe surface temperature 700 ℃ and above, the utility model discloses a resistance decline range is littleer, compares with prior art, is difficult for producing the electric leakage more.

Detailed Description
The utility model discloses it is further explained below with the accompanying drawings, like the ceramic heating tube that fig. 1 to 5 show, including the ceramic body 1 of cylinder type, fixed resistance wire 2, pin 3 and the welding piece 4 of setting in ceramic body 1, 2 evenly distributed of resistance wire are in ceramic body 1, and the range of 2 rules of resistance wire, and resistance wire 2 has two links for form the electric current return circuit after the connecting circuit, pin 3 has two, and respectively with the both ends electric connection of resistance wire 2, foretell two pins 3 promptly, one of them link welding of every pin 3 and resistance wire 2 is in the same place.
The one end setting of pin 3 is in the one end that ceramic body 1 kept away from heat conduction hole 11, and the fixed one end that is close to pin 3 at ceramic body 1 that sets up of welding piece 4, and the fixed welding of pin 3 is on welding piece 4, that is to say when two pins 3 are connected with resistance wire 2 respectively, and pin 3 is also fixed to be set up on welding piece 4, and welding piece 4 is fixed to be set up on ceramic body 1, and welding piece 4 and heat conduction hole 11 are located ceramic body 1's both ends respectively.
The cylindrical surface of the ceramic body 1 is longitudinally provided with a fixing groove 13, generally, when the ceramic body 1 is installed, an accommodating space for placing the ceramic body 1 is arranged in the electric soldering iron, a rail matched with the fixing groove 13 is arranged in the accommodating space, the fixing groove 13 and the rail are aligned, the installation of the ceramic body 1 is guided, and meanwhile, the ceramic body 1 is not easy to shake after being installed; one end of the ceramic body 1 close to the heat conduction hole 11 is provided with a step 14 around the circumference, and the step 14 is beneficial to clamping the ceramic body 1 in the electric soldering iron, so that the ceramic body is not easy to shake.
The working principle is as follows: through inciting somebody to action the utility model discloses install in the inside accommodation space of electric iron, accomplish the welding of other modules in pin 3 and the electric iron, lead to with the electric current to resistance wire 2, resistance wire 2 generates heat, and the heat realizes the transmission simultaneously to ceramic body 1's inside and outside through ceramic body 1 to make heat conduction to the flatiron of electric iron on.
