  • Patent number: 11484478
    Abstract: A method for making a composition for enamel regeneration proposes to encapsulate soluble calcium and phosphate salts within corresponding internal water phases in respective water-in-oil-in-water emulsions stabilized by solid particles, and add them to a toothpaste, enamel restoring gel or mouth wash base. In this way, the soluble calcium and phosphate salts can be present stably in the toothpaste, enamel restoring gel or mouth wash over a long period of time. When the toothpaste, enamel restoring gel or mouth wash of the present disclosure is used in oral cavity, the water-in-oil-in-water emulsions rapture under the effect of friction and pressing, releasing the soluble calcium and phosphate salts encapsulated within the corresponding internal water phases. As a result, the liquid in the user's oral cavity will contain high concentrations of calcium and phosphate ions, which can enhance the rate of enamel remineralization.

  • Patent number: 11323037
    Abstract: The present disclosure provides a forward converter with secondary LCD connected in series to realize excitation energy transfer, comprising a forward converter main circuit and an energy transfer and transmission circuit. The forward converter main circuit includes a high-frequency transformer T, a switching tube S, a diode D1, a diode D2, an inductance L1, and a capacitor C1. The energy transfer and transmission circuit includes a diode D3, a capacitor C2, and an inductance L2. The circuit structure of the present disclosure has simple circuit structure and high reliability. And the reverse recovery problem of the diode could be eliminated by the soft switch-off or soft switch-on of the switching tube, which further reducing the loss of switching tube and diodes and improving the overall efficiency. In addition, the excitation energy could be transferred to the load side to improve the energy transmission efficiency.

  • Patent number: 10988397
    Abstract: The present invention discloses a small integrated greening device and method for recycling wastewater, including a wastewater collection system, a microorganism and plant purification system, and a reclaimed water collection and distribution system. The method includes the following process: greywater or wastewater is collected through a pipeline and enters a water collection tank of a wastewater collection part. Lifting is performed by submersible sewage pumps, such that the lifted water enters a microorganism and plant synergistic purification and greening part. Each submersible pump is controlled by one corresponding automatic water level controller to transport the treated water to the reclaimed water-use sites.
