[0002] Power tools are a common type of electrical appliance used in daily life and work, and they come in a wide variety of types and functions. For example, a vacuum cleaner is a type of power tool that is widely used in the cleaning field, mainly for removing dust, debris, fallen leaves, and other debris from the ground. Specifically, a vacuum cleaner uses airflow to suck debris and dust into the machine or blow it away from the surface it was originally attached to, thereby achieving cleaning.

[0003] In existing blow-vacuum machines, the position of the suction pipe is fixed, and it can only perform suction or blowing operations without adjustment. In addition, in most current blow-vacuum machines, the dust collection bag used to collect debris after suction is located at the bottom, which also results in the blow-vacuum machine being large in size and inconvenient to store.

[0004] Based on the above-mentioned situation, this application further designs and improves the existing blow-suction machine. Utility Model Content

[0012] In a preferred embodiment, the fan structure includes a motor and a fan driven by the motor. The fan is located at the end of the blowing channel and guides the gas from the suction channel to the blowing channel. When working, it can drive the airflow to perform blowing and suction operations.

[0013] In a preferred embodiment, the end of the air intake channel has an arc-shaped wall, allowing the airflow to smoothly turn and pass through.

[0014] In a preferred embodiment, the blow-suction machine body is provided with a battery pack mounting position for mounting a battery pack.

[0025] See Figures 1 to 6 The present invention relates to an improved blow-vacuum machine, comprising a blow-vacuum machine body 1, wherein the blow-vacuum machine body 1 is provided with a fan structure, which guides the airflow when working. The blow-vacuum machine body 1 is provided with a blow-out port 2 and a suction port 3 facing the same direction; it also includes a ventilation pipe 5, which can be selectively installed on the blow-out port 2 or the suction port 3, and respectively form a blow-out working state and a suction working state.

[0026] Specifically, as shown in the attached drawings, the air outlet 2 is connected to the air blowing channel 21, and the air intake 3 is connected to the air intake channel 31. The air blowing channel 21 and the air intake channel 31 are arranged side by side, both facing the working area, for convenient use. The fan structure includes a motor 11 and a fan 12 driven by the motor 11.
