  • Patent number: 10085606
    Abstract: Applicants have created vacuum systems and apparatuses for cooling a vacuum device. The apparatus can include a cooling device adapted to couple with a vacuum device, at least one cooling device air inlet, and a cooling device outlet. The air flows from the air inlets to the air outlet and combines with air disposed within the vacuum device. The system can include the cooling device, a vacuum housing, and a vacuum interface such that air flowing from the air inlets to the outlet flows from the vacuum interface to the vacuum housing biased with a negative pressure area. As a result, the air originating from the air inlets cools the air disposed within the vacuum housing upon mixing and the vacuum device cools, thus increasing the vacuum device's performance. Furthermore, heat transfer from the vacuum device to an operator reduces, thus improving the productivity and comfort of the operator.

  • Patent number: 10084406
    Abstract: Exemplary embodiments or implementations are disclosed of methods, apparatus, and systems for operating motors in variable speed situations. In an exemplary implementation, a method of controlling a variable-speed motor includes defining a control duration as a predetermined number of cycles of a multiple-phase power supply. Each speed in a range of speeds is defined by a corresponding number of the cycles of the control duration. Power is provided to the motor from the power supply at a selected one of the speeds, by enabling input from the power supply for the number of the cycles of the control duration corresponding to the selected speed.

  • Publication number: 20180235420
    Abstract: Described are methods, apparatuses, and systems for securing a vacuum appliance to a vacuum device including a first locking adapter that includes a tab and a second locking adapter that includes a receiving slot. The first and second adapters form an airtight seal when the tab is received by the slot by rotating one adapter relative to the other. The receiving slot can include a slot terminus to restrict rotational movement of the first adapter relative to the second. The apparatus can further include a securing slot that can secure the tab within a slot terminus such that a portion of the second locking adapter adjacent to the receiving slot is adapted to flex. Through the described rotation, the first and second adapters tighten and become rigid thus minimizing both the slippage between these two elements and the leakage between the vacuum device and any attached appliances.

  • Patent number: 10049841
    Abstract: Applicant has created systems, methods, and apparatuses for controlling the power supply of a vacuum cleaner motor. The systems and apparatuses include pressure taps to detect a pressure differential within a vacuum cleaner, a float that adjusts depending on an amount of liquid stored, and a power switch that toggles based on the pressure differential created by the position of the float. Alternatively, the float can be replaced by an air chamber so that the pressure differential is created by liquid rising above the volume of air trapped in the chamber. The method can include interrupting the current supplied to an electrical circuit of a power switch based upon a pressure differential created within the vacuum. By controlling the power supply to a vacuum cleaner motor based on a pressure differential created by the amount of liquid stored within the vacuum cleaner, the vacuum cleaner can automatically disable the vacuum cleaner's motor as the vacuum approaches its maximum liquid capacity.
