In this embodiment, the power supply assembly 13 may be a storage battery, and the storage battery can store electric energy so as to be more flexible to move when in use. The battery can set up in handle 11 departments, further reduces the whole focus of garden instrument, and it is more convenient to use.

Furthermore, the handheld rod 100 is of a hollow structure, and a lead led out from the power supply assembly 13 can extend to the fan 21 from the inside of the handheld rod 100, so that the lead can be protected and the lead is prevented from being worn; on the other hand, the appearance of the garden tool can be tidier.

In this embodiment, the handle 11 is further provided with a switch assembly, the switch assembly is electrically connected with the power supply assembly 13, and the on-off of the power supply assembly 13 and the fan 21 can be controlled, so that the start and stop of the eave cleaning machine head 200 are controlled. Illustratively, the switch assembly may include a button or a push button, and the blower 21 is controlled to start or stop by pressing or pushing, which is convenient to operate.

It should be noted that, it is a relatively conventional means in the art to control the on/off between the battery and the electrical component through a switch assembly such as a push button or a push button, and any one of the switch assemblies in the prior art may be used in the present embodiment as long as the connection relationship, the specific structure, and the specific control manner between the switch assembly and other components are adopted, and the detailed description of the specific structure, the connection relationship with other components, and the specific control manner of the switch assembly is not described in detail herein.

In order to further improve the cleaning effect of the eave cleaning machine head 200, the eave cleaning machine head 200 further comprises an air duct 23, and the air duct 23 is communicated with the air outlet of the fan 21. By arranging the air duct 23, the function of gathering air flow generated by the fan 21 can be achieved, so that wind power is more concentrated, and the cleaning effect is improved.

For example, the cross-sectional area of the air guide duct 23 may be gradually reduced in the flow direction of the airflow to further concentrate the wind force.

For example, an opening at one end of the air duct 23 close to the outlet air may be flat, so that the air flow may form a relatively thin air knife, which is beneficial to improving the effect of the air flow on removing impurities.

In order to clean the dirt on the eave conveniently, the air duct 23 is further connected with a scraper knife 24, and the scraper knife 24 can scrape the dirt on the eave, so that the cleaning is more thorough.

In this embodiment, the scraper knife 24 and the air duct 23 are integrated, the scraper knife 24 can be formed by extending the bottom edge of the air duct 23, and the scraper knife 24 can not only scrape mud and remove dirt, but also further guide the air flow to flow along the scraper knife 24, so as to guide the air flow to the eave position, which is beneficial to improving the cleaning effect.
