Abstract: A double suction type sterilizing vacuum cleaner includes a base seat and an upper cover mounted on an upper side of the base seat. A main suction port is provided in the base seat. A hitting device is mounted on the base seat and adapted to hit a cleaning object under the base seat. A sterilizing lamp is mounted in the base seat for sterilizing purposes. A dust collecting box is detachably mounted to the upper cover and defines an air channel in communication with the main suction port. A secondary suction port is provided in the dust collecting box and in communication with the air channel. When the main suction port is blocked, an ambient air can be supplied to the air channel through the secondary suction port, facilitating the release of the blocking situation in the main suction port.

Abstract: A mop assembly includes a handle having a control member connected to a lower end thereof and the control member is located within a connection unit which is connected to the handle. A locking unit is connected to outside of the connection unit and is hooked to a main body. The main body includes a case in which a tank, a steam generation device and a pivotal member are located therein. An operation bar is pivotably connected to the case. The pivotal member is able to activate the steam generation device by pushing the handle downward. The main body can be disengaged from the locking unit and used individually. The steam generation device can be activated by operation of an operation bar on the main body.

Abstract: A steam generating device includes a body having a waterway defined longitudinally therein, and an inlet and an outlet are respectively connected to the body and communicate with the waterway. A heating tube is connected to the body and located close to the waterway. A pre-heat tube is connected to outside of the body and has a first end for introducing cold water into the pre-heat tube and a second end connected to the inlet. The cold water is pre-heated in the pre-heat tube before entering the waterway so that the water in the waterway is easily transferred into steam.

Abstract: A rotary paper trimmer includes work board and a blade unit is slidably engaged with the rail on the work board. The blade unit includes a space and a locking member is inserted into the space and biased by a spring. The locking member includes two hooks. A blade carrier carries a blade and includes two lugs which are inserted into two insertion holes in the blade unit. The lugs have two respective through holes with which the hooks of the locking member are engaged. The blade carrier is easily removed from the blade unit by pushing the locking member to disengage the hooks from the through holes of the lugs of the blade carrier, so that a new blade can be installed again.
