However, the valve stem (80) of the small air nozzle device has a conical flange during the manufacturing process. The distance between the largest diameter end of the portion (8 4 ) and the inner side wall of the airtight portion (92) is about 公·〇5 mm′′, so that the maximum diameter end of the conical flange portion (8 4 ) is larger than a predetermined size. In the case of an error, the valve stem (8 〇) may be locked with the lock (7 〇), and the tapered flange portion (- 8 4 ) will abut against the tapered hole portion (9 3 ) ( As shown in the sixth figure) • 'The contact area of the rubber ring (8 2 ) with the tapered hole portion (9 3 ) is small and cannot be in an urgent state, making the air leakage situation easy to occur, and generally occurs. The ratio of the above dimensional error is about 1%, such a high product defect rate, which increases the waste material generated in the manufacturing process and increases the cost. If it is to be reduced The ratio of the inch error and the precision of the size increase the cost of the valve stem (8 〇) and the improved manufacturing process. The increased cost leads to the low cost of the small nozzle device and reduces the user's use. Willingness, but can not be used universally.
