Abstract: A water stopping mechanism configured for a water outlet device comprises one or more pad members configured for elastic deformation. The one or more pad members are configured to be movably disposed in a water outlet chamber of the water outlet device. The one or more pad members at least define a position-providing space, and the one or more pad members comprise a water stopping position and an open position. When in the water stopping position, the one or more pad members elastically hermetically seal and abut an outer peripheral of one or more water outlet ports of the water outlet chamber to achieve water stopping and hermetical sealing, and the one or more pad members are configured to move toward the position-providing space due to increasing of water pressure in the water outlet chamber to terminate the water stopping and the hermetical sealing.

Abstract: The present disclosure discloses a structure for rapidly picking and placing a hand shower comprising a fixed portion, a shower body, and a trigger element. The fixed portion is movably disposed with a locking member, and the shower body is disposed with a locking matching portion. When the locking matching portion is locked to and matched with the locking member, the shower body is fixed relative to the fixed portion. The trigger element is movably disposed on the shower body. When the shower body is fixed relative to the fixed portion, the trigger element contacts the locking member, and movement of the trigger element is configured to drive the locking member to move to enable the locking member to be separated from the locking matching portion and to enable the shower body to be rapidly separated from the fixed portion.

Abstract: A method for determining a mining value of a leucogranite-hosted uranium deposit, including: determining average uranium grade, uranium occurrence, average uranium recovery rate, and uranium stripping ratio of the leucogranite-hosted uranium deposit in an exploration region, wherein the average uranium recovery rate is a ratio of a uranium recovery amount after hydrometallurgy to a total uranium amount, and the uranium stripping ratio is a ratio of an amount of rock to be stripped to a uranium ore amount in a mining process; and determining the mining value of the leucogranite-hosted uranium deposit in the exploration region, wherein the mining value of the leucogranite-hosted uranium deposit is determined based on one or more of the average uranium grade, the uranium occurrence, the average uranium recovery rate, and the uranium stripping ratio.

Abstract: A shower head comprises a body, a water outlet panel, and a switching member. The body comprises a valve cavity, a water inlet passage, a first water outlet passage, and a second water outlet passage, and each of the water inlet passage, the first water outlet passage, and the second water outlet passage is in communication with the valve cavity. The switching member comprises a valve rod portion and an elastic member. The water outlet panel is rotatably connected to the body and comprises a position-providing groove. When the position-providing groove is rotated to correspond to the valve rod portion, the valve rod portion is configured to be driven to be moved and switched to block the first water outlet passage, and the elastic member generates an elastic force.

Abstract: The present disclosure discloses a water outlet mechanism comprising a water outlet body, a driving assembly, an eccentric cam, a swinging plate, and one or more water outlet nozzles. The water outlet body comprises a water inlet port, a water outlet port, and a water-passing cavity in communication with the water inlet port and the water outlet port. The driving assembly is disposed in the water-passing cavity. The eccentric cam is rotatably disposed in the water-passing cavity and is operatively coupled to the driving assembly. The swinging plate is swingingly disposed in the water-passing cavity and is operatively coupled to the eccentric cam. The one or more water outlet nozzles are swingingly disposed on the swinging plate and are configured to be driven by the swinging plate to perform reciprocating movement of swinging in a front-and-rear direction.

Abstract: This invention provides a NMR multi-dimensional method for measuring coupling constants within several coupling networks. At first, a 90° hard pulse was performed to flip the magnetization from the Z axis to the XY plane. After t1/2, a selective 180° pulse is implemented with a simultaneous Z-direction gradient, thus reversing different protons at different slices. Then the PSYCHE element is implemented. After another t1/2, the gradient G1 and Gp are implemented. At last, the EPSI readout is used to simultaneously record both the chemical-shift and the spatial information. As a result, from different specific slices, we can extract the scalar couplings between the proton reversed at this slice and other protons. These couplings lead to splittings in the indirect dimension, from which relevant coupling constants can be measured.
