    摘要: A vacuum cleaner includes an air inlet, a filter, a fan, and a main air outlet. The filter has a clean side and an unclean side. An unclean air chamber is formed between the air inlet and the unclean side of the filter. A first air chamber is formed between the clean side of the filter and the fan. An air outlet chamber is formed between the fan and the main air outlet. The upstream end of the air outlet chamber is connected to the first air chamber. An airflow may enter the vacuum cleaner from an external environment via the air inlet under the action of the fan, and sequentially passes through the unclean air chamber, the filter, the first air chamber and the air outlet chamber the main air outlet. The vacuum cleaner may include a self-cleaning air passage and an air supply air passage.

    摘要: A telescopic tube device includes a first tube assembly, a second tube assembly slidably connected relative to the first tube assembly, and an operating unit disposed at a sleeved position between the first tube assembly and the second tube assembly. The operating unit includes an operating member, a first locking member, a second locking member, and a limiting member. When in a locked state, the limiting member is at an initial position, and the first locking member and the second locking member remain engaged; when in at least one released state, the limiting member is offset from the initial position, and the first locking member and the second locking member are disengaged. At least one elastic member provides the limiting member with a pulling force so that the limiting member has a tendency to remain at the initial position. A related vacuum cleaner is disclosed.

    摘要: A rod mechanism for a garden tool having a main body includes a first rod pivotally connected to the main body and movable between an in-use position and a storage position. A locking component engages the main body to lock the first rod in one of the in-use position and the storage position. An actuator moves between a released position and a triggered position, the actuator when in the triggered position unlocking the locking component from the main body, the actuator when in the released position orienting the locking component so as to be lockable to the main body. A second rod connected to the first rod moves to a preset position allowing the actuator to move to one of the triggered position or the released position. A position sensor on the main body generates a sensing signal when the first rod pivots to at least one of the in-use position and the storage position.

    摘要: A rolling brush assembly includes a rolling brush having a rolling brush roller, at least two brush bars, and a protruding strip extending lengthwise along an axis. Each brush bar extends lengthwise in a longitudinal direction of the rolling brush roller. The brush bars are arranged at intervals along a circumferential direction of the rolling brush roller with the protruding strip located between adjacent two brush bars. The at least two brush bars are fixed on the rolling brush roller in one of a flocking or an inserting manner. An engagement portion is formed between the brush bars and the rolling brush roller. A distance from an outer end of the engagement portion to the axis is less than a distance from an outer end of the protruding strip to the axis.

    摘要: A shielding structure is disposed around a camera of a mower, in a front of a forward direction of the mower. The shielding structure includes a first shielding plate, a second shielding plate, and a third shielding plate. The shielding plates from a lens surface of the camera. The first shielding plate is disposed above the camera to shield sunlight from a top of the camera. The second and third shielding plates are disposed on two sides of the camera to shield sunlight from the two sides of the camera. The shielding plates may be formed unitarily or separately, and they may be removably and/or retractably attached to the mower. The shielding plates may be arranged so that the shielding structure flares outwardly in the downward direction.
