The present invention provides a hand-held electric tool comprising a housing and an operating component. The housing has a main body section and a grip section extending from the rear side of the main body section, and the front end of the main body section is provided with a mounting interface. The operating component is mounted at the mounting interface of the housing and protrudes from the housing. A chip removal hole is formed in the bottom wall of the main body section of the housing, and a protective portion that extends downwards at least partially is provided at the bottom end at the position where the main body section joins the grip section. The bottom of a hand-held electric tool of the present invention is substantially closed, except for being provided with a chip removal hole, which allows removal of chips while preventing a user's hand from being inadvertently extended into the housing and contacting a component operating at a high speed. Moreover, chips removed through the chip removal hole are blocked by the protective portion, without reaching the grip section, which offers considerable advantages in terms of safety and hygiene.

Hand-held electric tool

An outdoor cleaning device configured to clean outdoor surfaces using a variety of fluids and techniques. The outdoor cleaning device includes a brush head, a motor and a transmission for providing a driving force to the brush head, a fluid tank for storing a fluid (e.g., a cleaning solution or detergent), and a controller for controlling mixing (or not mixing) the fluid stored in the fluid tank during operation of the outdoor cleaning device. The controller may enable fluid from the cleaning tank to be mixed with a second fluid (e.g., water) prior to being dispensed via at least one nozzle. The at least one nozzle may be secured to a guard cover via grooves on an inner guard cover and an outer guard cover. The nozzle(s) enables the distribution of cleaning fluids in various directions, enhancing the brush head's cleaning capability.
