Abstract: A hand warmer charging case includes an accommodating housing and an accommodating cover. The accommodating housing is provided with a storage space for storing a target hand warmer. The accommodating housing is further provided with an accommodating space. The accommodating space is configured to accommodate a rechargeable power supply and a circuit board matched with the rechargeable power supply. The accommodating cover is movably connected to the accommodating housing in a movable manner, and is configured to close or open the storage space. During use, the accommodating cover that cooperates with the accommodating housing is opened to opening the storage space provided in the accommodating housing. A power bank hand warmer that needs to be charged or is temporarily in idle is put into the storage space, and the accommodating cover that cooperates with the accommodating housing is closed, thereby closing the storage space provided in the accommodating housing.
Abstract: Provided is a board-to-board socket, including a socket body, socket terminal, and socket strengthener. The socket body includes a bottom wall, socket side walls, socket guide parts formed at lateral ends of the socket body, and an island part protruding upwards from the bottom wall. Socket guide parts each include a plug guide part receiving cavity, longitudinal outer peripheral wall, and lateral outer peripheral walls. The socket strengthener includes a main body part, lateral outer peripheral wall, and elastic arm parts. Tops of the elastic arm parts bend and extend towards longitudinal outer sides to form hitching part cavities hitched on top faces of the lateral outer peripheral walls.
Abstract: A hand crocheting device and a hand crocheting are provided. The hand crocheting device includes a main body and an adjusting mechanism. The main body includes a first end and a second end. The adjusting mechanism is located at the second end. The adjusting mechanism includes a first clamping baffle fixed to the second end and a second clamping baffle facing the first clamping baffle. The first clamping baffle and the second clamping baffle cooperatively define a clamping slot for receiving a yarn. The second clamping baffle is movable relative to the first clamping baffle to adjust a size of the clamping slot, such that a tension on the yarn is adjustable.
Abstract: A camera module includes a circuit board, a lens assembly, and a first board. The circuit board includes a first surface, a second surface opposite to the first surface, a first sidewall, and a second sidewall opposite to the first sidewall. Each of the first sidewall and the second sidewall connects the first surface to the second surface. The lens assembly is disposed on the first surface. The first board is connected to the first sidewall. The first board is inclined or perpendicular to the first surface. The first board is disposed on a side of the lens assembly.
Abstract: The present invention relates to a bone conduction speaker and its compound vibration device. The compound vibration device comprises a vibration conductive plate and a vibration board, the vibration conductive plate is set to be the first torus, where at least two first rods inside it converge to its center; the vibration board is set as the second torus, where at least two second rods inside it converge to its center. The vibration conductive plate is fixed with the vibration board; the first torus is fixed on a magnetic system, and the second torus comprises a fixed voice coil, which is driven by the magnetic system. The bone conduction speaker in the present invention and its compound vibration device adopt the fixed vibration conductive plate and vibration board, making the technique simpler with a lower cost; because the two adjustable parts in the compound vibration device can adjust both low frequency and high frequency area, the frequency response obtained is flatter and the sound is broader.
Abstract: Provided are an electronic atomization device (1) and a smoke-generating assembly (40), the electronic atomization device (1) comprising a baking unit (80), the baking unit (80) comprising a baking chamber (310); the electronic atomization device (1) also comprising a smoke-generating assembly (40) accommodated in the baking chamber (310); the smoke-generating assembly (40) comprising a solid smoking medium and a turbulent flow member (41) embedded in the solid smoking medium.
