Blowing and sucking device
The invention relates to a blowing and sucking device which comprises a shell, a fan, a motor and a working accessory, the fan and the motor are mounted in the shell, the working accessory is connected to the shell, the shell is provided with an air inlet, an air outlet and an air pipe portion located at the air outlet, and airflow generated by rotation of the fan driven by the motor flows into the shell from the air inlet and flows out from the air outlet. The working accessory is detachably connected to the air pipe part, the working accessory is provided with a first locking part, the air pipe part is provided with a second locking part matched with the first locking part, and the first locking part is buckled to the second locking part so as to fix the working accessory to the shell; the blowing and sucking device comprises a pop-up structure located between the air pipe part of the shell and the working accessory, and when the first locking part and the second locking part are tripped, the pop-up structure pushes the working accessory to be separated from the shell. The pop-up structure is arranged between the working accessory and the shell, when locking between the working accessory and the shell is relieved, the working accessory is automatically popped up under the action of the pop-up structure, and a user can replace the working accessory conveniently.
本发明涉及一种吹吸装置，包括壳体、安装于壳体内的风扇与电机、及连接于壳体的工作附件，壳体设有进风口、出风口及位于出风口处的风管部，电机驱动风扇旋转产生的气流自进风口流进壳体内并自出风口流出，工作附件可拆卸地连接于风管部，工作附件设有第一锁定部，风管部设有与第一锁定部配合的第二锁定部，第一锁定部扣合于第二锁定部以将工作附件固定于壳体；吹吸装置包括位于壳体的风管部与工作附件之间的弹出结构，第一锁定部与第二锁定部脱扣时，弹出结构抵推工作附件脱离壳体。本发明通过在工作附件和壳体之间设置弹出结构，解除工作附件与壳体之间的锁定时，工作附件在弹出结构的作用下自动弹出，方便用户更换工作附件。
