摘要： 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.

摘要翻译：申请人已经创建了用于控制真空吸尘器电机的电源的系统，方法和装置。系统和设备包括用于检测真空吸尘器内的压力差的压力抽头，根据储存的液体量调整的浮子以及基于由浮子的位置产生的压力差切换的功率开关。或者，浮子可以由空气室代替，使得压力差通过在捕获在腔室中的空气体积上方升高而产生。该方法可以包括基于在真空中产生的压力差来中断提供给功率开关的电路的电流。通过基于由真空吸尘器中存储的液体量产生的压力差来控制对真空吸尘器电动机的供电，当真空接近其最大液体容量时，真空吸尘器可以自动禁用吸尘器的电动机。

摘要： A vacuum comprising a canister and a removable lid assembly that is configured to couple to the canister. The lid assembly includes a motor, an impeller coupled to the motor, a filter mounting structure configured to receive a filter element, and an impeller inlet with curved inner walls. These curved inner walls help to minimize air flow path disruptions.
