Abstract: The present disclosure discloses an anti-siphonage water storage device, a sanitary water supply device, and a sanitary cleaning device. The anti-siphonage water storage device is set in a cleaning water path of a sanitary cleaning device, and the anti-siphonage water storage device comprises a water tank for storing cleaning water. The water tank is disposed with a water inlet structure and a water outlet structure, and the water tank is disposed with an overflow structure. A water outlet surface of the water inlet structure is higher than an overflow surface of the overflow structure.

Abstract: The present disclosure discloses a foaming spraying device and a foaming toilet. The foaming spraying device comprises a foaming spraying body. The foaming spraying body comprises a foaming cavity, a suction port, an accelerating hole, and a foam spraying port, each of which is in communication with a foaming cavity. The accelerating hole is configured to enable a foaming solution to be accelerated to enter the foaming cavity of the foaming spraying body, so that the foaming cavity of the foaming spraying body generates negative pressure to suck air through the suction port and the air is mixed with the foaming solution to form foam.

Abstract: A foaming device comprises a valve body, a pump, and a self-suction spray head. The valve body comprises a water inlet port, a liquid inlet port, a mixing cavity, and a liquid outlet port. Each of the water inlet port, the liquid inlet port, and the liquid outlet port is in communication with the mixing cavity, and an input end of the pump is connected to the liquid outlet port to enable the mixing cavity to generate a negative pressure to suck water and foaming agent respectively from the water inlet port and the liquid inlet port for mixing. The self-suction spray head is connected to an output end of the pump, and the self-suction spray head comprises a first air inlet hole and a spray hole to enable mixed liquid to be mixed with air to produce foam to be sprayed out.

Abstract: A liquid outlet device and a liquid outlet system are provided. The liquid outlet device includes an outer housing assembly provided with a liquid inlet flow channel and a liquid outlet member installed to the outer housing assembly. The liquid inlet flow channel can form a liquid discharge opening on the outer housing assembly. The liquid outlet member can be enclosed with the outer housing assembly to form a liquid outlet flow channel. A protrusion part of the liquid outlet member can elastically abut against the outer housing assembly, and seal the liquid discharge opening disposed opposite to the protrusion part, so that the liquid can act positively on the protrusion part under the action that the liquid pressure of the liquid inlet flow channel exceeds a preset value. The protrusion part can further reset against the liquid pressure less than or equal to the preset value.

Abstract: An isolated cell membrane potential detection system can measure a cell membrane current change when light having different parameters such as wavelength, energy density, pulse width, and repetition rate stimulates a cell to be detected, to detect whether the biological electrical activity of the cell can be regulated by light, and to detect the specificity of the light regulation parameters of the cell. In the light regulation cell membrane potential detection system, a method of progressively adjusting and detecting with multiple optical parameters from small to large is used to measure a cell membrane current change in different periods under a certain photostimulation parameter for each group of cells, so as to quickly and efficiently detect which type of optical signal can regulate the characteristics of the cell such as the generation of a membrane current, photostimulation parameter specificity, and an energy threshold.

Abstract: A system to predict a fatigue life of an aluminum alloy is disclosed herein. The system comprises a computer-readable medium cooperative with micromechanics-based fatigue life models for cyclic multiaxial loading. The fatigue life models predict the fatigue life by processing information received by the system relating to the aluminum alloy and the stress state present in the aluminum alloy. The received information comprises at least one of: a critical shear plane, a damage factor, a hardening factor defined by at least one of a plurality of uniaxial cyclic hardening factor parameters related to probabilistics of defects and microstructure characteristics in the aluminum alloy, an additional hardening factor related to non-proportionality, and thermophysical and mechanical properties of the aluminum alloy.
