The utility model relates to a high-flow-precision diaphragm pump cover structure and a miniature diaphragm water pump and relates to the technical field of fluid conveying devices.The pump cover structure comprises a cover body, a water outlet pipe, a water inlet pipe and a backflow piece, the water outlet pipe and the water inlet pipe are both fixedly connected with the cover body, and the backflow piece comprises a backflow part and a pressure control opening and closing part; a pressure stabilizing plate is arranged in the water outlet pipe, and a pressure stabilizing cavity is formed in the side, away from a water outlet of the water outlet pipe, of the pressure stabilizing plate. Under the condition that an external pipeline connected with the water outlet pipe is not blocked, after water flow enters the water outlet pipe, relatively stable internal pressure is formed in the pressure stabilizing cavity due to the existence of the pressure stabilizing plate, and the size of the internal pressure is determined by the size of the cross sectional area in the water outlet pipe blocked by the pressure stabilizing plate and is not influenced by the external pipeline. The same water outlet cross sectional area is matched with the same flow speed to determine the consistency of the water outlet amount, and therefore the pump cover structure can effectively improve the accuracy of controlling the fluid conveying amount.

This application provides a mobile terminal, comprising a housing, a circuit board, a card holder, a card tray, and a toggle mechanism. The housing has a card tray mounting hole. The circuit board is located inside the housing, and the card holder is located on the circuit board, forming a receiving cavity. The card tray is movably disposed within the receiving cavity and is inserted into or removed from the cavity through the card tray mounting hole. At least one of the card tray and the housing has an ejection hole. The toggle mechanism has a pivot shaft, which is located outside the projection of the card tray in the direction of movement and connected to the housing or the card holder. The two ends of the toggle mechanism are a pin action end and a card tray ejection end, with opposite directions of movement. When the pin applies force to the pin action end, the pin action end moves inward into the housing, and the card tray ejection end pushes the card tray away from the housing, thus ejecting the card tray. This mobile terminal reduces the size of the card tray structure, facilitating the overall internal layout of the mobile terminal, simplifying manufacturing and installation, and saving costs. The toggle mechanism has better installation space, which is beneficial for designing and implementing a reliable and durable structure.

The horizontal bearing moving body of the filling machine comprises a transverse moving frame, a longitudinal reinforcing frame, an upper guide beam, a lower supporting beam and a driving belt assembly, the transverse moving frame is of a square frame structure and is transversely arranged, and the longitudinal reinforcing frame is integrally in a U shape and is vertically connected to the rear side of the transverse moving frame. The vertical height of the whole longitudinal reinforcing frame is the same as that of the transverse moving frame; the upper guide beam is fixedly connected to the top of the longitudinal reinforcing frame and horizontally arranged, and the lower supporting beam is fixedly connected to the bottom of the longitudinal reinforcing frame, vertically corresponds to the upper guide beam and is parallel to the upper guide beam. The whole horizontal bearing moving body of the filling machine is in an L shape, the whole moving body and all process devices on the moving body can be borne on the single side through the transverse moving frame, the longitudinal moving plate can move in a reciprocating mode through the upper guide beam and the lower supporting beam, and therefore the stability of a whole integrated process module can be kept, the structural space is optimized, and the production efficiency is improved. And the occupied space is smaller.

This application relates to the field of energy storage device technology, specifically disclosing a battery pack and an electrical device. The battery pack includes battery cells, a protection board, and an overcurrent electronic protection element. Each battery cell includes a cell body and a first tab. A first side of the cell body has a top sealing edge extending along a first direction. The first tab extends from the top sealing edge, forming a top sealing groove between the top sealing edge and the first side. The protection board extends along the first direction and is at least partially located within the top sealing groove. The overcurrent electronic protection element is disposed on the protection board, and the first tab is electrically connected to the protection board through the overcurrent electronic protection element. This battery pack can fully utilize the idle space of the battery cells, increasing the cell capacity within the same package volume, or reducing the overall volume of the battery pack while maintaining the same cell capacity, thereby increasing the energy density of the battery pack.
