Embodiment 1

[0041] Such as figure 1 - Figure 4 As shown, this embodiment provides a docking device, including: a first docking structure 1, including: a first metal coil 11, suitable for connecting the first AC power line 6, and a first insulating shell 12 surrounding the first metal coil 11 The second docking structure 2 includes a second metal coil 21, which is suitable for connecting the second AC power line 7, and the second insulating shell 22 surrounding the second metal coil 21; the metal core 3, which is suitable for at least part of the same time in the working state It is arranged in the first metal coil 11 and the second metal coil 21 .

[0042] In this embodiment, the metal core 3 is arranged inside the first insulating shell 12 or the second insulating shell 22 , the metal core 3 is an iron core, and the current in the first AC wire 6 and the second AC wire 7 is AC. The working state refers to the state in which one of the AC wires of the docking structure has been connect...

Embodiment 2

[0056] In this embodiment, the arrangement of the metal core 3 in the above-mentioned docking device can be changed, and the docking device in this embodiment can be commonly used in cooling fans.

[0057] The metal core 3 is arranged on the outside of the first insulating shell 12 and the second insulating shell 22, the first insulating shell 12 and the second insulating shell 22 are provided with inner recesses, and the two ends of the metal core 3 are detachably arranged in the inner recesses , and pass through the first metal coil 11 and the second metal coil 21 provided in the first insulating shell 12 and the second insulating shell 22 .

[0058] Because there is a constantly changing magnetic field inside the metal core 3, no current passes through, and due to the barrier of the insulating shell, water will not come into contact with the metal coil, and will not cause effects such as leakage, so it can overcome the split cooling fan in the prior art There is a defect of...

Abstract

The invention provides a butt joint device and a cooling fan, and the device comprises a first butt joint structure which comprises a first metal coil suitable for being connected with a first AC wireand a first insulation shell surrounding the first metal coil; a second butt joint structure which comprises a second metal coil suitable for being connected with a second alternating current wire and a second insulation shell surrounding the second metal coil; and a metal core which is suitable for being at least partially and simultaneously arranged in the first metal coil and the second metalwire in a working state. According to the butt joint device, the metal coils is arranged in an insulating shell according to the principle of a transformer, direct contact between the conductive partsis avoided, so that the butt joint device is prevented from electric leakage due to contact between the conductive parts and the outside in the power-on process, the power utilization safety is ensured, wireless transmission of current is realized, meanwhile, the voltage of an electric wire can be adjusted, and the application range is wider.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a docking device and a cooling fan. Background technique [0002] The cooling fan adopts the principle of water evaporation effect, and uses physical methods to achieve cooling, which solves the problems of excessive discharge of "Freon" and high energy consumption in ordinary air conditioners. It usually uses a cooling pad as a cooling medium, and water flows from the top of the cooling pad along the cooling pad. The corrugated surface flows down evenly, so that the wet curtain is evenly moistened from top to bottom. When the fan is pumping air, it generates pressure to force unsaturated air to flow through the surface of the porous wet curtain, converting a large amount of damp heat in the air into latent heat. Forcing the air entering the room from the dry bulb temperature to close to the wet bulb temperature increases the humidity of the air, making the dry hot a...
