Suction nozzle device, washing and sweeping vehicle and washing and sweeping method
The invention provides a suction nozzle device, a washing and sweeping vehicle and a washing and sweeping method. The suction nozzle device comprises a substrate, a housing assembly, a pipeline assembly, an opening and closing device, and a reset piece. A first opening part and a second opening part on the pipe wall of the pipeline assembly are both communicated with the inner cavity of the housing assembly, and part of an inner hole of the pipeline assembly and the inner cavity of the housing assembly form a suction channel; the opening and closing device is movably arranged in the suction channel, the opening and closing device is arranged at the second opening part in a communicating manner, and the opening and closing device has an opening state for opening the pipeline assembly and aclosing state for closing the pipeline assembly; the reset piece is arranged in the suction channel and applies a reset force to the opening and closing device; when the suction force in the suction channel is smaller than or equal to the reset force, the opening and closing device is in a closed state; and when the suction force in the suction channel is larger than the reset force, the opening and closing device is switched from the closed state to the opened state. According to the technical scheme, a problem that in the prior art, the negative pressure in the box body is generated slowly and unstably is effectively solved.
本发明提供了一种吸嘴装置、洗扫车及洗扫方法，其中，吸嘴装置，包括：基板；壳体组件；管道组件，管道组件的管壁上的第一口部和第二口部均与壳体组件的内腔连通，管道组件的部分内孔与壳体组件的内腔形成抽吸通道；开合装置，可活动地设置在抽吸通道内，开合装置穿设于第二口部，开合装置具有打开管道组件的打开状态和关闭管道组件的关闭状态；复位件，位于抽吸通道内，并向开合装置施加复位力，其中，当抽吸通道内的抽吸力小于或者等于复位力时，开合装置处于关闭状态，当抽吸通道内的抽吸力大于复位力时，开合装置由关闭状态切换至打开状态。本申请的技术方案有效地解决了相关技术中的箱体内负压产生缓慢且不稳定的问题。
