Definitions
- the invention relates to the technical field of engine electric heating devices, in particular to a ceramic glow plug.
- the glow plugs of conventional diesel engines or burners all adopt a single-wire structure, and the metal shell connected to the equipment body is connected to the negative pole of the power supply to form a circuit.
- the patent application number CN96230894.3 discloses a ceramic glow plug, including a shell , a metal cap, a heating wire and a heating body, the wire is connected to the metal cap, and forms a circuit with the shell to energize the heating body.
- the patent application number US5880432A which discloses a ceramic heating device, which adopts a single-wire structure, and forms a circuit through the conduction of the shell to make the ceramic heater generate heat. stuffed work.
- the purpose of the present invention is to provide a ceramic glow plug to solve the problem of electromagnetic interference.
- the present invention adopts the following technical solutions.
- a ceramic glow plug comprising a housing and a heating element, the heating element is arranged inside the housing, and the positive wire is connected to the top of the heating element, characterized in that the housing includes an upper housing and a lower housing body, the positive lead and the negative lead pass through the upper case at the same time, and the negative lead is connected to the heating element.
- a notch is provided on the lower casing.
- the notch is arranged on the top of the lower casing.
- the negative lead wire is conductively connected to the middle part of the heating element through the slot.
- an insulating layer is provided between the heating element and the lower casing.
- an insulating layer is provided between the heating element and the upper casing.
- the gap between the heating element and the upper casing is filled with insulating material.
- the lower case is mated with the upper case, and the upper case wraps the notch of the lower case.
- Electromagnetic interference is any device, equipment or system that is generated during conduction or under the action of an electromagnetic field accompanied by voltage or current. It adopts a two-wire structure to completely isolate the positive and negative poles from the housing. The circuit that needs to be protected is wrapped in the housing, which can effectively prevent the interference of the electric field or magnetic field. At the same time, the two poles are charged to prevent short circuit, and the single wire Parts such as terminal blocks and insulating rings, the structure is simpler.
- Fig. 1 is the sectional view of ceramic glow plug in embodiment 1;
- Fig. 2 is a three-dimensional schematic diagram of a ceramic glow plug
- Fig. 3 is a structural schematic diagram of the lower housing
- Fig. 4 is a sectional view of the upper housing
- a ceramic glow plug includes a casing and a heating element 2, the heating element 2 is arranged inside the casing, and the casing includes an upper casing 3 and a lower casing.
- the casing 1, the positive lead wire 5 and the negative lead wire 4 are introduced from above the upper case 3, the upper case 3 wraps the positive lead wire 5 and the negative lead wire 4 at the same time, and the positive lead wire 5 is connected to the heating element 2 At the top, the negative lead wire 4 is connected to the middle of the heating element 2, and forms a loop with the heating element 2 when the positive and negative lead wires are energized, so that the heating element 2 heats up rapidly.
- the top of the lower casing 1 is provided with a notch 6, the negative lead wire 4 is welded to the middle of the heating element 2 through the notch 6, and the notch 6 provides the connection between the negative lead wire 4 and the heating element 2 During welding, high temperature is generated and the negative lead wire 4 is connected with the heating element 2 to form solder joints.
- the notch 6 provides a space for accommodating the negative lead wire 4 to be welded on the heating element 2 The solder joints produced during welding, the stronger the soldering, the more stable the conductivity, and it replaces the traditional single-wire terminal, and the structure is simpler.
- a layer of ceramic insulating layer is provided between the heating element 2 and the upper casing 3 and the lower casing 1, and the ceramic insulating layer can connect the heating element 2 to the upper casing 3 and the lower casing 1.
- the lower casing 1 is connected together, and plays the role of insulation and non-conduction.
- the gap between the heating element 2 and the upper casing 3 is filled with insulating ceramic cementitious material, and the ceramic cementitious material will gradually solidify when heated. , which is used to isolate the heating element 2 from the upper casing 3, and at the same time wrap the positive and negative wires to protect the wires.
- the notch is matched with the upper casing 3, and the interface of the upper casing 3 wraps the notch 6 to keep the overall appearance intact.
- a ceramic glow plug is screwed into each combustion chamber wall of the engine.
- the ceramic glow plug provides heat to improve the starting performance.
- the ceramic glow plug is required to heat up quickly and maintain a high temperature state for a long time
- the low-voltage power supply will be connected to the positive and negative wires.
- the heating element 2 When the current flows through the heating element 2, the heating element 2 will be in a red hot state, and the combustible mixture entering the cylinder will rise on the piston.
- the temperature When it is compressed, the temperature will rise immediately, and the heat of the ceramic glow plug has reached the self-ignition point of the mixture, so the mixture starts to burn, producing high-temperature and high-pressure gas, which pushes the piston to do work.
