Abstract: A wall-mounted and table-type dual-purpose fan includes a fan body and a fixing support connected with the fan body and comprising a base, fixing legs fixed to the base and directly placed on an installation surface, a hook and a fixing screw; when the fan needs to be fixed to the installation surface, the hook penetrates through the base and is fixed to the base and the installation surface through the fixing screw. The structure used for fixing and supporting is light and compact, and the fan can be fixed to wall surfaces through only one screw and is easy and convenient to install; furthermore, the fixing legs can adapt to various installation surface conditions and provide good fixing and supporting effects; furthermore, the fan body has an adjustable degree of rotating freedom in two directions, and large adjustable angles and flexible air supply direction selection are achieved.

Abstract: A foldable electric fan, including a pressing-down part, a limiting base and a sliding pressing plate for restriction is provided. By pushing one end of the sliding pressing plate for restriction to extend and penetrate through the locking-through channel, the pressing plate for restriction is on top of the movable front supporting base, the fixed supporting base and the movable rear supporting base at the same time. Then when the pressing-down part is exerting pressure on the sliding pressing plate for restriction, the pressing plate for restriction is able to press on the movable front supporting base, the fixed left and right supporting base and the movable rear supporting base at the same time in order to enable the sliding pressing plate for restriction to press tightly on the base, which is easy for operation, simple in structure and not easy to produce scattered components. At the same time, the turnover mechanism further reduces the occupied space of the foldable electric fan.

Abstract: A universal rotary fan is provided including a supporting mechanism, a cylinder, a front net cover, a rear net cover, fan blades and a control mechanism, wherein the cylinder is mounted on the supporting mechanism; the front net cover and the rear end cover are arranged respectively on the front end face and the rear end face of the cylinder, the fan blades are located inside the cylinder; and the control mechanism is electrically connected with the fan blades. The supporting mechanism includes a support fixedly connected with the cylinder, and a rotating mechanism fixedly connected with the bottom end of the support. The rotating mechanism includes a bottom support, a pedal arranged at one end of the bottom support, a plug pin, and a turnplate body matched and connected with the plug pin, and the turnplate body is fixedly connected with the bottom of the cylinder.

Abstract: An oscillating fan, by adding an oscillating motor, to drive the drive gear to move along the periphery of the fixed gear, the oscillating motion of the fan is achieved is disclosed. The fan motor is only used for driving the blades to blow air in a rotating mode, so that the load of the fan motor is reduced, and the oscillating motion stability of the blades driven by the drive gear is ensured. Meanwhile, the installation space of the oscillating and rotating pivot part is reduced, so that the whole oscillating fan is small in size, convenient to transport.

Abstract: A foldable electric fan, comprising: a fan head, a support tube and a base, a turnover mechanism for turning the fan head up or down is provided between the top of the support tube and the fan head, is disclosed. Further, the base is foldable, and the electric fan can be arranged into a desk fan or a floor fan by turning the fan head up or down, and can be used for several different purposes in more broad fields. The fan head and the base of the electric fan can be folded-up, which reduces the space it occupies and cuts down the cost of package and transportation. Moreover, the foldable electric fan effectively reduces the inconvenience of traditional electric fans which need to be detached into several parts during package and transportation, and then assembled together for use.

Abstract: The present invention relates to a process for preparing an alloy composite negative electrode material having a spherical carbon matrix structure for lithium ion batteries by spray-drying carbothermal reduction.

Abstract: The present utility model relates to ventilation products, and particularly to a drum fan. The drum fan comprises a cylindrical housing (1), a front grid guard (3) at a front end face of the cylindrical housing (1), a rear grid guard (4) at a rear end face of the cylindrical housing (1) and fan blades (2) for wind supply, characterized in that the fan blades (2) are totally or partially disposed outside the rear end face of the cylindrical housing (1). The drum fan is advantageous in a large wind supply, a low noise and a longer wind supply distance and can be extensively applied in factories, farms, warehouses and other public sites.

Abstract: The present invention relates to wind supply devices, particularly to an omnidirectional electric fan, comprising a support frame, characterized in that a support ring is movably connected to the support frame, and a fan body is movably connected in the support ring so as to turn to left and right in the support ring. The electric fan not only enables the fan body to swing up and down in a perpendicular direction but also swing to left and right in a horizontal direction, thereby turning at a large angle, providing a broader wind supply scope and facilitating use.

Abstract: The present disclosure relates to the field of ventilation technique. A multifunction lighting electric fan includes a fan body for blowing, a base plate for supporting the fan body and an illuminating device connecting to the fan body. The illuminating device in the present disclosure can be turned freely to change the irradiation direction of the light. The lighting electric fan can both ventilate and light, which satisfy the using needs in the evening. Because the irradiation direction of the lamplight can be adjusted, the lighting electric fan can be used widely and achieve high applicability.
