A paper-plastic electronic cigarette shell comprises a lower outer support, an inner support, an upper outer support and a cigarette holder. A clamping cavity with an upward opening is formed in the lower outer support, and a first cigarette holder embedding groove and a first through groove are formed in the two sides of the clamping cavity respectively; the inner support is glued in the clamping cavity of the lower outer support from top to bottom, the inner support is provided with a first accommodating cavity with an upward opening, and two sides of the inner support are respectively provided with a second cigarette holder embedding groove and a second through groove; the upper outer support covers the lower outer support and the inner support from top to bottom, the upper outer support is provided with a second containing cavity with a downward opening, and a third cigarette holder embedding groove and a third through groove are formed in the two sides of the upper outer support. In addition, the utility model further provides an electronic cigarette with the paper-plastic electronic cigarette shell. According to the utility model, by designing the structure that the plurality of layers of supporting shells are glued and assembled, the electronic cigarette shell can be produced, assembled and formed more easily and simply, and the shell is made of full-paper-plastic materials, so that the electronic cigarette shell is high in quality, low in price and more environment-friendly; the utility model has the advantages of strong practicability and strong popularization significance.

This utility model discloses a novel nut anti-loosening structure, relating to the field of mechanical fastener technology, and applicable to plastic electronic products, home appliances, automotive parts, and other fields. The structure includes a plastic housing, a metal nut embedded within the housing, and an anti-loosening plastic hole located at the outlet end of the threaded hole of the metal nut, all three being coaxially arranged. The diameter of the anti-loosening plastic hole is smaller than the nominal diameter of the screw and is integrally formed with the plastic housing; the metal nut is injection-molded and embedded within the housing. After the screw passes through the threaded hole of the metal nut, it is screwed into the anti-loosening plastic hole. The elastic deformation of the plastic generates a continuous radial clamping force and axial frictional resistance, effectively preventing the screw from loosening under high-frequency vibration or temperature change environments. This structure requires no additional anti-loosening parts, is low-cost, simple to manufacture, compact in structure, provides long-lasting anti-loosening force, and has high reliability, solving the problems of easy loosening in traditional structures and high cost of existing solutions.

This utility model relates to the field of modular wireless charging technology, specifically a modular plastic electronic device holder for wireless charging. The utility model includes a holder body, on which a wireless charging module body is fixedly installed on the lower inner wall of the wireless charging slot. This utility model uses a clamping adjustment component to clamp the electronic device from both sides, achieving stable clamping and adapting to electronic devices of different sizes and weights. It provides stable support and fixation for the electronic device, ensuring that the electronic device maintains optimal alignment with the wireless charging module body during charging. Compared to some traditional holders on the market that use magnets to attach the back of the electronic device for charging, this avoids the electronic device shifting during charging, compromising the alignment accuracy between the wireless charging coil and the device's receiver, and thus preventing wireless charging interruption.

The invention belongs to the technical field of plastic electronic packaging, and particularly relates to a packaging process for preventing packaging layering of a power device. Comprising the following steps: welding a chip on a lead frame; carrying out plasma cleaning on the lead frame welded with the chip; uniformly mixing a silane coupling agent and a diluent to obtain a glue solution; debugging the height of a glue spraying head, a glue spraying path and a glue spraying speed, so that the silane coupling agent is uniformly sputtered on the surface of the chip; carrying out plasma cleaning on the lead frame after spraying is completed again; carrying out plastic package curing on the chip by using a plastic package material to obtain a plastic package piece; in the plastic package curing process, glue solution molecules and a plastic package material are subjected to chemical reaction to form firm chemical bonds. The problems that in the prior art, after a large chip power device is packaged, due to the fact that the bonding strength of a plastic packaging material and the surface of the chip is insufficient, the layering defect is prone to occurring, the reliability of the device is reduced, and the service life is shortened are solved.
