Blowing and sucking safety conversion device of blowing and sucking machine
The invention discloses a blowing and sucking safety conversion device of a blowing and sucking machine, which comprises a blowing and sucking machine shell, a blowing and sucking conversion part, a rotating ring, a shell cover, a switch assembly and a limiting assembly, a triangular bulge and a limiting groove are arranged on the rotating ring, the rotating ring is in running fit with a mounting ring, a bulge loop is arranged on the shell cover, the bulge loop is matched with the mounting ring and limits the rotating ring. The blowing and sucking conversion component is inserted into the convex ring and is in running fit with the rotating ring, a switch push button is arranged on the switch assembly, the blowing and sucking conversion component penetrates through the limiting groove and abuts against the switch push button at the circuit connection position, the switch push button is separated from the blowing and sucking conversion component at the circuit disconnection position, and the limiting assembly is detachably connected to a blowing and sucking machine shell. The limiting assembly is provided with a V-shaped protrusion and a front limiting block, and when the circuit connection position is converted to the circuit disconnection position, the front limiting block and the blowing and sucking conversion component are clamped to form a disassembly buffering position. According to the device, the buffer position is removed, so that the effect of prolonging the conversion operation time is achieved.
本发明公开了一种吹吸机的吹吸安全转换装置，包括吹吸机机壳、吹吸转换部件、旋转圈、机壳罩、开关组件、限位组件，旋转圈上设有三角凸起、限定槽，旋转圈与安装环转动配合，机壳罩上设有凸环，凸环与安装环配合并对旋转圈进行限位，吹吸转换部件插入凸环内并与旋转圈转动配合，开关组件上设有开关推钮，接通电路位置下吹吸转换部件穿过限定槽并与开关推钮抵触，断开电路位置下开关推钮与吹吸转换部件脱离，限位组件拆卸式连接在吹吸机机壳上，限位组件上设有V形凸起、前限位块，接通电路位置向断开电路位置转换时前限位块与吹吸转换部件卡合并形成拆除缓冲位置。本发明具有拆除缓冲位置，从而达到延长转换操作时间的效果。
