Problems solved by technology

[0003] However, the gear adjustment knob on the general vacuum cleaner uses a positioner to achieve gear shifting, or mechanical gear shifting. Only the shift knob can return to its original position, and consumers need a knob that can automatically reset after adjusting the vacuum cleaner gear position. This kind of shift knob on the market cannot meet the needs of consumers.

Abstract

The invention discloses an automatic reset gear shifting knob comprising a fixing seat, a reset device, a knob arranged on the fixing seat, a contact part connected with the knob and contact switches arranged at two sides of the contact part respectively; and the reset device is long strip-shaped, one end of the reset device is connected with the contact part, and the other end of the reset device is connected with the fixing seat. The automatic reset gear shifting knob provided by the invention is convenient and fast for gear shifting and capable of realizing automatic reset after gear shifting, thus meeting the requirements of consumers.

Description

Technical field [0001] The invention relates to an automatic resetting gear adjustment knob, in particular, to an automatic resetting gear adjustment knob used on a vacuum cleaner. Background technique [0002] With the development of science and technology, the living standards of human beings are constantly improving. The vacuum cleaner, a product of science and technology, as a practical cleaning tool, brings convenience to indoor cleaning and improves people's comfort in life. [0003] However, the gear adjustment knob on the general vacuum cleaner uses the positioner to realize the gear shift, or the mechanical gear shift. After adjusting to the corresponding gear position, the position of the knob will stop at the gear position unchanged. The shift knob can be returned to the original position, and consumers need a knob that can automatically reset after adjusting the gear position of the vacuum cleaner. Such shift knobs on the market cannot meet the needs of consumers. Sum...
