This utility model relates to an electronic cigarette filling and air intake structure, aiming to solve the problems of complex structure, large size, difficult assembly, and poor sealing caused by the separation of the filling port and air intake port in existing electronic cigarettes. The structure includes a cavity (10), a nesting part (20), and a silicone kit (30). The cavity is divided into an oil chamber (12) and an air chamber (13) by a partition (11). The silicone kit is fixed by the nesting part and has a protruding post (31) on it, which integrates the filling port and the side wall through hole (32), connecting the oil chamber and the air chamber respectively, realizing functional integration. The groove (33) is located below the oil chamber and has a built-in oil suction part (40). The nesting part can be quickly assembled through the locking slot and locking protrusion structure, and an optional oil baffle plate (50) can be added to prevent oil leakage. This design is highly compact, simplifies the number of parts, facilitates automated production, reduces volume, and improves sealing and user experience.

The application discloses a kind of flame-retardant high-flexibility crosslinked polyethylene insulated power cable and preparation method thereof, belong to cable technical field.The inside to outside includes conductor, insulating layer, filling layer, tape layer and sheath layer in proper order.Conductor uses the 5th or 6th soft copper conductor, insulating layer includes polyethylene, ethylene-vinyl acetate copolymer and magnesium hydroxide modified by vinyltriethoxysilane and polybutadiene, filling layer is alkali-free glass fiber rope coated with aluminum hydroxide powder on the surface, prepared by impregnation-extrusion process, sheath layer includes DOPO-PEG and pentaerythritol phosphate ester compounded intumescent halogen-free phosphorus flame-retardant system and organic modified montmorillonite.The application realizes efficient halogen-free flame-retardant by multilayer synergistic flame-retardant design, and has high flexibility and good weather resistance simultaneously.

The utility model discloses a water seal well for a blow-off pipeline, which comprises a well body, the well body comprises a well seat, a shaft and a well lid, the upper end of the well seat is in socket connection with the lower end of the shaft, the well lid is arranged at the top of the shaft, a hollow water seal tank is formed in the middle of the well seat, and water seal liquid is filled in the water seal tank; a water inlet pipe and a water outlet pipe are connected to the peripheral side of the well base, the water inlet pipe is connected with an indoor blow-off pipeline, and the water outlet pipe is used for discharging sewage and gas; the end, connected with the well base, of the water inlet pipe is further connected with a flow guide pipe, the end, away from the water inlet pipe, of the flow guide pipe extends into the water seal tank, and an outlet of the flow guide pipe is located in water seal liquid of the water seal tank. According to the water seal well for the blow-off pipeline, the water seal effect of the water seal well is stable and reliable, harmful gas of an outdoor blow-off pipe network can be effectively prevented from entering a room, the water seal well is particularly suitable for a blow-off pipeline system of a farm, diseases are reduced, and breeding benefits are improved.
