Fig. 4 is a schematic view of the mounting structure of the adjusting sleeve of the present utility model.
In the present embodiment, the following description will be made by taking the case where two adjustment sleeves (the first adjustment sleeve 41 and the second adjustment sleeve 42) having the same size are provided, and adjusting the protruding length of the ignition needle by adjusting the installation position of the adjustment sleeve as an example:
as shown in fig. 4 (1), the first adjusting sleeve 41 and the second adjusting sleeve 42 are respectively disposed at the front end and the rear end of the positioning section 12 (i.e., the ignition section 11 and the connecting section 13 are disposed at the front end and the rear end of the positioning section, respectively, and are respectively sleeved with an adjusting sleeve), when the ignition section is mounted, the front end of the limiting sleeve 30 is abutted against the rear end of the adjusting sleeve disposed on the connecting section 13, and the first adjusting sleeve 41, the positioning section 12 and the second adjusting sleeve 42 are all wrapped inside by the fixing sleeve 20, at this time, the ignition section 11 extends out of the fixing sleeve by a length L1.
As shown in fig. 4 (2), on the basis of fig. 4 (1), the second adjusting sleeve 42 is detached from the connecting section 13 and sleeved on the ignition section 11, the second adjusting sleeve 42 is tightly attached to the first adjusting sleeve 41, when the adjusting sleeve is installed, the front end of the limiting sleeve 30 is abutted against the rear end of the positioning section 12, the first adjusting sleeve 41, the positioning section 12 and the second adjusting sleeve 42 are wrapped inside the fixing sleeve 20, and at this time, the length of the ignition section 11 extending out of the fixing sleeve is L2, and L2< L1.
As shown in fig. 4 (3), on the basis of fig. 4 (1), the first adjusting sleeve 41 is detached from the ignition section 11 and sleeved on the connecting section 13, the second adjusting sleeve 42 is tightly attached to the first adjusting sleeve 41, when the adjusting sleeve is installed, the front end of the limiting sleeve 30 is abutted against the rear end of the first adjusting sleeve 41, the positioning section 12 and the second adjusting sleeve 42 are all wrapped inside the fixing sleeve 20, at this time, the length of the ignition section 11 extending out of the fixing sleeve is L3, and L2< L1< L3.
The installation position of the adjusting sleeve can be adjusted to adjust the extension length of the ignition needle, and the principle is as follows: because the length of the connecting section 13 is fixed, when the adjusting sleeve is placed on the connecting section 13, the front end part of the limiting sleeve is abutted against the rear end face of one adjusting sleeve positioned at the tail end, and the position corresponding to the limiting sleeve moves backwards relative to the ignition needle, so that the front end position of the fixing sleeve 20 moves backwards relative to the ignition needle 10, the extending length of the ignition needle is prolonged, and conversely, when the adjusting sleeve is moved to the ignition section 11 positioned at the front end, the position of the limiting sleeve moves forwards relative to the ignition needle 10, and the front end position of the fixing sleeve 20 moves forwards relative to the ignition needle, so that the extending length of the ignition needle is shortened. That is, the distance between the front end surface of the stop collar 30 and the rear end surface of the positioning section 12 is changed by adjusting the number of the adjusting collar between the stop collar 30 and the positioning section, thereby changing the length of the ignition needle 11 extending out of the fixing collar 20.
In practice, the fixing sleeve 20 is usually fixed, and the mounting position of the adjusting sleeve can be adjusted in the above manner, so that the position of the ignition needle can be adjusted, and the length of the ignition needle extending out of the fixing sleeve 20 can be changed, so that the ignition needle can be adapted to burners with different ignition size requirements. The mode adjusting sleeve is positioned inside the fixed sleeve, the volume of the ignition needle assembly is not changed, the structure is simple and small, the installation does not occupy space, and the adjusting mode is also particularly simple.
