Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of household appliances, in particular to a toggle switch for household appliances. Background Art
[0002] A toggle switch, also known as a slide switch or rocker switch, is a common electrical switch used to control the on / off of a circuit. It operates by toggling the switch handle to change the state of the internal contacts, thereby connecting or disconnecting the circuit.
[0003] The working principle of a toggle switch is based on a mechanical structure. When the switch handle is toggled, the internal contacts move, thereby changing the connection state of the circuit.
[0004] Typically, one end of a toggle switch is connected to a power source, and the other end is connected to a load. By toggling the switch handle, the connection between the contacts and the power source and the load is made or broken, thereby achieving control of the circuit.
[0005] At present, most toggle switches have a core part that opens and closes the switch gate, which uses a protrusion on the core surface to fit into a groove in the gate housing to adjust and fix the switch opening and closing points. However, this design method is prone to loosening after long-term use. In addition, some households install switches in locations that are easy for children to touch. In order to prevent children from arbitrarily operating the switch, a limit structure needs to be designed to prevent the switch from being arbitrarily operated and turning on the appliance when it is not in use.

A first arc-shaped opening is provided on one side of the gate housing, and a handle is fixed on the surface of the gate core, and the handle is arranged to slide in an arc shape within the first arc-shaped opening.
[0009] The gate housing is further provided with a second arc-shaped opening at the lower end of the other side, a conductive plate is fixed on the surface of the gate core, and the conductive plate is arranged to slide in an arc shape inside the second arc-shaped opening;
[0010] A ceramic sleeve is fixed to the bottom of the switch housing through a plastic bracket, and a conductive rod is fixed inside the ceramic sleeve. A conductive block is welded and fixed to one end of the conductive rod. The conductive block is a spherical structure and corresponds to the position of the conductive plate.
[0011] In detail, the back of the switch housing is provided with an integrally formed mounting plate. There are four mounting plates, which are symmetrically distributed in pairs along the back of the switch housing. Mounting holes are provided inside the mounting plates.
[0012] In detail, a pin groove is provided inside the gate core, a bayonet is slidably sleeved inside the pin groove, and the end surface of the bayonet is an arc surface.
[0013] In detail, a spring is provided inside the pin groove, and two ends of the spring are fixedly assembled with the inner wall surface of the pin groove and the surface of the bayonet respectively.
[0014] In detail, the inner wall surface of the gate housing is respectively provided with a first arcuate groove and a second arcuate groove, the specifications of the first arcuate groove are the same as those of the second arcuate groove, and the inner arcuate surface of the first arcuate groove is slidably fitted with the arcuate end surface of the bayonet.
[0015] In detail, a threaded sleeve is fixedly provided through the bottom of the switch housing, a threaded rod is provided on the internal thread of the threaded sleeve, a knob is fixed on the lower end of the threaded rod, a limiting column is provided on the upper end of the threaded rod, the limiting column is provided in contact with the conductive plate, and the limiting column is made of hard rubber material.
[0016] In detail, a copper alloy bracket is welded and fixed on one side of the conductive plate, and a conductive seat is welded and fixed on the other end of the copper alloy bracket and the other end of the conductive rod. A wire groove is provided inside the conductive seat, and a threaded hole connected to the conductive groove is provided at the upper end of the conductive seat. The inner thread of the threaded hole is connected to a fastening screw.
[0017] The design scheme proposed by the utility model has the following beneficial effects during application:
[0018] 1. The toggle switch can drive the gate core to rotate in the gate housing by manually toggling the handle. Through the squeezing effect, the bayonet currently located in the first arc-shaped groove can be squeezed into the pin groove through the arc surface. Then, it moves with the gate core. After moving to the second arc-shaped groove position, it can be rebound into the second arc-shaped groove through the reset of the spring, thereby fixing the handle and synchronizing the conductive plate to contact the conductive block and realize the connection of the circuit.
[0019] 2. When the electrical appliance is not in use and is disconnected, in order to prevent children from turning on the switch at will, you can turn the knob to drive the threaded rod and the threaded sleeve to move relative to each other, so that the limit column can contact the conductive plate in the closed state to achieve limit blocking, thereby preventing children from turning the handle at will and turning on the switch.
