Description

Technical Field

[0001] The invention relates to the technical field of household appliance power supply connection, and in particular to a connection device for turning on and off power of a household appliance. Background Art

[0002] Household appliances mainly refer to various electrical and electronic appliances used in homes and similar places, also known as civil appliances and daily appliances. These appliances use electricity as their main energy source to help people perform household chores such as cooking, food preservation, cleaning, etc., while also providing a variety of cultural and entertainment conditions.

[0003] When using a standing electric fan, the fan wires often get entangled on the column. In this case, the wire harness needs to be manually rotated, adjusted and moved so that the wire harness has sufficient length to be close to the required blowing area. In order to effectively optimize the winding situation and further extend the wire length to meet the use of sufficient length in daily life, we propose a connection device for turning on and off power of household appliances.

[0024] 5. The present invention effectively increases the contact area between the roller and the vertical electric fan by setting the roller to be larger at both ends and smaller in the middle, making it easier to lock the vertical electric fan axially in the radial rotating structure.

[0025] 6. The present invention drives the meshing turbine to rotate by rotating the transmission shaft to cause the worm gear part, and causes the roller to rotate 90 degrees through the rotation operation.

The present invention installs the power-on and power-off connection device on the vertical electric fan through the arrangement of the connector housing component 1 and the double elastic spring 3, and cooperates with the arrangement of the ball 2 so that the connection device can perform the expansion and contraction work of lifting and sliding and radial free rotation adjustment. The combination of the two methods can optimize the winding of the wire, and can further extend the length of the wire to meet the use of sufficient length in daily life.

[0040] Specifically, the connector housing assembly 1 includes a lower movable sleeve 101 and an upper movable sleeve 102 sleeved on the outside of the lower movable sleeve 101; a connecting buckle A1011 fixedly connected to one end of the double elastic spring 3 is provided at the lower end of the lower movable sleeve 101; a connecting buckle B1201 fixedly connected to the other end of the double elastic spring 3 is provided at the upper end of the upper movable sleeve 102.
