Description
Technical field
The utility model relates to a kind of tubular type zirconia-type oxygen sensor.
Background technology
At present, automobile has been a kind of universal vehicles, of many uses, and convenient, lambda sensor has become most important functional part in the combustion control technology, so, in order can to improve the quality of products, can energy savings in the use procedure, now be badly in need of a kind of have easy to use, measure accurately, respond the combustion atmosphere measurement mechanism of the advantage such as rapid.
The utility model content
The purpose of this utility model provides a kind of tubular type zirconia-type oxygen sensor, overcomes complex structure in the existing product, and measuring accuracy is lower, and response speed waits not enough more slowly.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of tubular type zirconia-type oxygen sensor; comprise stube cable; the stube cable outside is provided with over cap; be provided with the insulating ceramics that matches with stube cable in the over cap; insulating ceramics is connected with the contact spring; the over cap end is connected with shell; be provided with air admission hole between described over cap and the shell, outer shell outer wall is provided with the installation screw thread, and enclosure is provided with tubular zirconium-oxide; tubular zirconium-oxide inside is provided with contact bush; the contact spring is connected with the contact bush end, and the tubular zirconium-oxide inwall is provided with inner conducting layer, and tubular zirconium-oxide outer wall end is provided with outer conducting layer; the shell end is provided with protection tube, and protection tube is provided with the intake and exhaust groove.
The beneficial effects of the utility model are: a kind of tubular type zirconia-type oxygen sensor that the utility model provides, have the advantages such as simple in structure, that response is rapid, it is easy, easy to use to safeguard, measurement is accurate, can improve the quality of products, shorten the production cycle, simultaneously, reasonably regulative mode can energy savings.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the cut-open view of the described a kind of tubular type zirconia-type oxygen sensor of the utility model embodiment.
Among the figure:
1, stube cable; 2, over cap; 3, insulating ceramics; 4, contact spring; 5, shell; 6, air admission hole; 7, screw thread is installed; 8, tubular zirconium-oxide; 9, contact bush; 11, inner conducting layer; 12, outer conducting layer; 13, protection tube; 14, intake and exhaust groove.
Embodiment
As shown in Figure 1; the described a kind of tubular type zirconia-type oxygen sensor of the utility model embodiment; comprise stube cable 1; stube cable 1 outside is provided with over cap 2; be provided with the insulating ceramics 3 that matches with stube cable 1 in the over cap 2; insulating ceramics 3 is connected with contact spring 4; over cap 2 ends are connected with shell 5; be provided with air admission hole 6 between described over cap 2 and the shell 5; shell 5 outer walls are provided with installs screw thread 7; shell 5 inside are provided with tubular zirconium-oxide 8, and tubular zirconium-oxide 8 inside are provided with contact bush 9, and contact spring 4 is connected with contact bush 9 ends; tubular zirconium-oxide 8 inwalls are provided with inner conducting layer 11; tubular zirconium-oxide 8 outer wall ends are provided with outer conducting layer 12, and shell 5 ends are provided with protection tube 13, and protection tube 13 is provided with intake and exhaust groove 14.
During use, zirconia-type oxygen sensor is contained on the exhaust pipe of automobile by screw thread 7 is installed, by air admission hole 6, air enters tubular zirconium-oxide 8, the tail gas of automobile enters protection tube 14 by intake and exhaust groove 14, and wherein, inner conducting layer 11 and outer conducting layer 12 are platinum electrode, oxygen concentration in the gas at tubular zirconium-oxide 8 surfaces externally and internally places has very big difference, will produce voltage between platinum electrode; When combination gas is rare, the content of oxygen is high in the exhaust, tubular zirconium-oxide 8 interior outside oxygen concentrations are poor little, the voltage very low (near 0V) that produces between the two poles of the earth, the outside in tubular zirconium-oxide 8 elements, otherwise, as almost there not being oxygen in the exhaust, voltage high (being about 1V) between outside in tubular zirconium-oxide 8 elements, then notify the ECU(electronic control unit), ECU judges the low or high of air-fuel ratio according to the electromotive force difference from lambda sensor, and correspondingly controls the time that oil spout continues.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection domain of the present utility model.
