The utility model relates to the technical field of filtering devices, and provides a filtering device which comprises a funnel, the first filter cartridge is arranged in the funnel, and the outer wall of the first filter cartridge abuts against the inner wall of the funnel; the sealing cover is arranged at the opening of the first filter cartridge and is used for sealing the first filter cartridge; the piston rod is vertically and slidably arranged in the center of the sealing cover, and the outer side of one end of the piston rod abuts against the inner wall of the first filter cartridge; the sealing plug is arranged in the liquid inlet and used for sealing the liquid inlet. By means of the technical scheme, the problem that in the prior art, the funnel is low in liquid filtering efficiency is solved.

The utility model relates to the field of brassieres, in particular to flat and skin-fitting adjustable underwear which comprises an underwear body and an air bag assembly, the underwear body comprises a cup part and a back surrounding part, the cup part is provided with two cups, a bottom band and a heart-shaped part, and the air bag assembly comprises a skin-fitting fabric layer, an adhesive layer, an inner inflatable film layer and an outer inflatable film layer. The inner surface of the adhesive layer is connected with the outer surface of the fabric layer in an adhesive mode, the outer surface of the adhesive layer is connected with the inner surface of the inner inflatable film layer in an adhesive mode, the peripheral edge of the outer surface of the inner inflatable film layer is connected with the inner surface of the outer inflatable film layer in an adhesive mode, and an inflatable space is defined between the outer surface of the inner inflatable film layer and the inner surface of the outer inflatable film layer. And the outer surface of the outer inflatable film layer is connected with the inner surface of the lower band. When the air bag assembly is inflated, the outer inflatable film layer bulges towards the cups, and the inner inflatable film layer is not expanded towards the skin-friendly fabric layer, so that the skin-friendly fabric layer can be flatly attached to the breasts, and the wearing skin-friendly degree and comfort are good.

This utility model belongs to the field of toothpaste production technology, specifically relating to a vacuum homogenizing emulsifier, including a tank, a circular plate, a rotary drive mechanism, a stirring mechanism, a top plate, a lifting drive mechanism, multiple infusion pipes, a distribution box, and multiple spray blocks. This utility model achieves a smooth and flat internal surface by ensuring the spray blocks are perfectly fitted into the fan-shaped movable holes, thus avoiding material residue or dead zones in the stirring process and improving emulsification uniformity. During cleaning, the spray blocks detach from the movable holes and extend into the tank, then rotate forward and backward along the movable holes, forming a fan-shaped spray through the spray nozzles on both sides. This comprehensively covers the inside of the tank, maximizing the cleaning coverage area, eliminating blind spots, and achieving a highly efficient and comprehensive cleaning effect.

The utility model belongs to the technical field of food seasoning, and particularly relates to a seasoning food flavoring device. Comprising a tasty tank, a control key is arranged on the tasty tank, an auxiliary lifting mechanism is arranged outside the tasty tank, an isolation frame is arranged on the auxiliary lifting mechanism, and a non-contact stirring mechanism is arranged in the tasty tank. Through structural improvement and optimization and the principle that like poles repel each other and unlike poles attract each other between the magnets, the rotating disc can be driven to rotate and stir, direct mechanical contact is avoided, maintenance is more convenient, and the inner surface of the flavoring tank is smooth and convenient to clean; and through lifting of the electric hydraulic rod, the purpose of auxiliary work can also be achieved, and the overall work is more labor-saving.
