Description
Technical Field
The utility model relates to a ceramic heating technical field especially relates to a nucleic acid amplification is pottery piece that generates heat for appearance.
Background
The nucleic acid detection becomes one of the important means for preventing various infectious diseases, the nucleic acid detector is commonly adopted in various hospitals and detection centers to carry out amplification test on collected samples, whether infection exists is judged according to test data, and the test method is specifically divided into three steps: 1. sample denaturation; 2. annealing the primer; 3. the enzyme catalyzes DNA chain extension synthesis at a proper temperature; in the process, the solution is heated by adopting a heating element, and the traditional heating element adopts a PTC heating element and a resistance wire winding mode, so that the resistance wire is easy to oxidize; PTC heat generating body has large heat decay; directly influences the test accuracy.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that the prior art is not enough to overcome, a long service life, the even ceramic piece that generates heat for nucleic acid amplification appearance of temperature that generates heat is provided.
The utility model adopts the technical proposal that: the utility model discloses a mounting panel and load board and heating circuit, the wire casing has been seted up on the mounting panel, the wire inslot is equipped with the wire, heating circuit sets up on the load board, the load board has been laid one side of heating circuit with the mounting panel is connected, the wire casing is in the through-hole has been seted up to the electrode department of heating circuit, be equipped with the electric conductor in the through-hole, external power source in the wire contact provides the electric energy, through the electric conductor, the electric current gets into the electrode of heating circuit begins to heat, the mounting panel with the load board is the potsherd, and the pottery has good insulating effect and heat conduction effect.
Optimally, the lead is a silver thin sheet, and the electric conduction performance and the heat conduction performance of the metallic silver are optimal.
Optimally, a thermistor and a thermal reset switch are arranged on the lead, the temperature is monitored through the thermistor, and when the temperature of the heating plate is too high, the thermal reset switch is switched off due to the increase of the current because of the reduction of the resistance.
Preferably, the wires are at the same level on the surface of the mounting plate.
Preferably, the mounting plate and the load plate are connected by welding or bonding.
Preferably, the mounting plate and the load plate are both in a conical sheet shape.
The utility model has the advantages that: the utility model discloses an use the potsherd as mounting panel and load board, the circuit cooperation that generates heat has avoided the PTC to generate heat the piece because the factor that the thermal decay is big has increased the precision of test to the cooperation through thermistor and hot reset switch has realized the control and the regulation to the temperature.
