| 181 | Brushless vacuum cleaner | US11051820 | 2005-02-04 | US07555812B1 | 2009-07-07 | Craig A. Pinney |
| The brushless vacuum cleaner is an electrical cleaning device that would feature conventional components from traditional upright vacuum cleaners but would use forced air to agitate debris from the surface to be cleaned. The brushless vacuum cleaner would consist of a base unit with multiple air injectors on the bottom, a pump case located on top of the base unit, a collection unit extending upward from the pump case, a vacuum chamber connecting the bottom of the base unit to the collection unit, and a handle that features various control buttons. The pump case would contain an electrical motor which would operate a dual-cycle agitator responsible for pulsing air flow through alternating air injectors on every other cycle. This system would replace the beater brush found on conventional upright vacuum cleaners, thus creating less wear and tear to carpeting and prolonging the life of the carpet. | ||||||
| 182 | Handheld Portable Devices for Touchless Particulate Matter Removal | US12170203 | 2008-07-09 | US20090044372A1 | 2009-02-19 | Jeremy F. Knopow; Steven Merrill Harrington; Andrew L. Banka |
| Handheld portable devices for dislodging and capturing particulate matter that has accumulated on various surfaces or structures are provided. The devices create opposing airflows that can intimately interface with each other during use. A vacuum airflow is drawn into the device, defining a vacuum affected zone upon the surface being cleaned. A high pressure airflow is emitted that penetrates through or passes adjacent to the opposing vacuum airflow and contacts the surface being cleaned, dislodging particulate matter therefrom. The high pressure airflow can be emitted from multiple nozzles as a series of airflow bursts that discretely contact the surface being cleaned. The configuration of each nozzle, as well as the overall arrangement and positions of all the nozzles together, are selected to impart the desired particulate matter dislodging characteristics to the device. | ||||||
| 183 | Apparatus for protecting motor of a vacuum cleaner | US11389215 | 2006-03-27 | US07487570B2 | 2009-02-10 | Tak-soo Kim; Hyoung-min Cho; Doo-han Yang |
| A motor protection apparatus for a vacuum cleaner includes: a motor chamber adapted to mount a motor; a penetration hole formed on a partition surrounding the motor chamber; a valve member configured to move between a first position closing the penetration hole and a second position at a distance from the penetration hole; and a casing adapted to be connected to an inner wall of the partition to surround the valve member and to guide movement of the valve member. A casing distance between an inner circumference of the casing and the valve member is minimized when the valve member is in the first position and maximized when the valve member is in the second position. | ||||||
| 184 | Dust collecting unit for vacuum cleaner | US11363171 | 2006-02-28 | US07462210B2 | 2008-12-09 | Jae Hong Lee |
| A dust collecting unit for a vacuum cleaner is provided. The dust collecting unit includes a filter assembly for filtering foreign objects coupled to a dust collecting cover which covers a dust collecting canister (320). The dust collecting canister receives and air foreign object mixture and accumulates the foreign objects therein. The filter assembly is disposed inside the dust collecting canister and filters out the foreign objects from the mixture. A damper assembly that selectively provides outside air to the inside of the dust collecting cover is positioned within the dust collecting cover. When pressure within the vacuum cleaner is increased due to an excessive amount of foreign objects accumulated in the canister, the damper assembly is activated to allow entry of outside air to relive the internal pressure and avoid a fan motor overload. In this manner, the damper assembly can quickly react to an increase in internal pressure and avoid damage to the fan motor cause by an overload. | ||||||

| A floor tool for use in vacuum cleaning floor surfaces includes a sole plate for engaging with a floor surface, a supporting body for the sole plate having means such as wheels or rollers for allowing the body to ride along the floor surface and an outlet conduit for coupling to a wand of a vacuum cleaner. The outlet conduit is mounted to the support platform by a connecting arm, a first end of the connecting arm being pivotally connected to the outlet conduit about a first axis and the second end of the connecting arm being pivotally connected to the supporting body about a second axis. The first and second axes are substantially parallel to one another. Fluid flow from the sole plate can be carried by a flexible hose or by the connecting arm itself. | ||||||

| The invention relates to a vacuum cleaning device comprising a dirt collection container which has a suction inlet and is in flow connection with at least one suction unit via at least one filter and at least one suction line, and comprising at least one external air inlet which opens into the suction line downstream of the at least one filter and is adapted to be closed by means of at least one closing valve, the closing valve having a movable valve body which, in a closed position, bears against at least one valve seat so as to form one or more sealing lines, the at least one sealing line delimiting an area which, in the closed position of the closing valve, is acted upon by a differential pressure. In order to develop the vacuum cleaning device in such a way that the at least one closing valve is of structurally simple design and the at least one filter can be completely cleaned within a short period of time, the invention proposes that the square of the total length of all sealing lines is at least 25 times the total size of all areas which are delimited by the sealing lines and acted upon by a differential pressure. | ||||||
