  • Patent number: 12644538
    Abstract: Methods, devices, and systems are described for a system including a rotation motor configured to rotate a valve seal holder, the valve seal holder having at least one pass-through interface and closed-off interface, a camshaft coupled to the valve seal holder, and a controller communicatively coupled to the rotation motor and the camshaft. The controller is configured to separate at least one of the pass-through interface or the closed-off interface of the valve seal holder from the seat configured to interface with the external system. The controller is configured to rotate, using the rotation motor, the valve seal holder until at least one of the pass-through interface or the closed-off interface is aligned with the seat. The controller is configured to compress the at least one of the pass-through interface or the closed-off interface against the seat to create a seal over the seat.

  • Publication number: 20200325019
    Abstract: Provided is an ozone generating assembly, including a conductive pillar, an insulating sleeve sleeved on an outer periphery of the conductive pillar, a conductive sleeve sleeved on an outer periphery of the insulating sleeve, and insulating brackets arranged at two ends of the conductive pillar and used to arrange an inner wall of the conductive sleeve and an outer wall of the conductive pillar in parallel and at an interval. Air guiding holes are uniformly distributed on an outer peripheral surface of the conductive sleeve, and an ozone channel is formed by the air guiding holes and a gap between the inner wall of the conductive sleeve and an outer wall of the insulating sleeve. Further provided is an ozone generator, which is low in energy consumption, good in heat dissipation effect, and high in ozone release efficiency.
