  • Patent number: 10618502
    Abstract: The disclosed vacuum cleaner system for an automobile fits in a cavity in the vehicle and has a tank that can be removed in a lateral direction without tools and without detaching the vacuum hose. A circuit board that carries an electronic controller is positioned alongside the motor and extends generally parallel to both the axis of the motor and the lateral direction in which the tank is removed. Cooling air is drawn though a cooling air inlet on the cabin wall to the circuit board, and then one side of the motor, through the center of the motor, to the cooling fan. From there, it is blown into a cavity where it joins exhausted working air from the vacuum and is exhausted from the vehicle through an air release opening that leads to the exterior of the vehicle.

  • Patent number: 10589405
    Abstract: A speed increasing bidirectional mechanical converter, including a main shaft and a speed increasing planet gear unit is disclosed. The speed increasing planet gear unit includes a first ring gear, a planet gear, a sun gear and a planet carrier, wherein the planet gear is mounted on the planet carrier. The planet gear is arranged between the first ring gear and the sun gear, and rotates in an opposite direction against the sun gear. The speed increasing bidirectional mechanical converter further includes a reversing means, via which the first ring gear and the sun gear drive the main shaft. When in use, the planet carrier is kept still, and the main shaft rotates in the preset direction. The speed increasing bidirectional mechanical converter realizes the direction reverse by using the speed increasing planet gear unit, which simplifies the structure, facilitates the manufacture and decreases the space it occupies and its weight.

  • Patent number: 10582819
    Abstract: A vacuum plate converts a conventional wheelbarrow into a wet and dry dual purpose vacuum cleaner receptacle. Collection of fluids and solids directly into a wheelbarrow simplifies larger cleaning tasks, small flood remediation, transport of bulk particulate materials such as sand, pea stone, and mulch, and allows hydro-excavation to be carried out in home improvement and small scale professional landscaping projects. A fluid level sensor prevents the wheelbarrow from overflowing when collecting large quantities of fluid, and a sump pump allows fluids to be drained from collected slurries, leaving only solids in the wheelbarrow for reuse or independent disposal.
