Description

Technical Field

[0001] This utility model relates to the field of range hood switch technology, specifically to a range hood switch. Background Technology

[0002] A range hood, also known as a kitchen exhaust hood, is a kitchen appliance used to purify the kitchen environment. It is typically installed above or near the stove to quickly remove combustion waste and harmful fumes produced during cooking, expelling them outdoors to reduce pollution and purify the air. The control panel of a range hood features power switch labels, which are used to indirectly control the mechanical or touch buttons on the circuit board, thus enabling different function modes.

[0003] Existing range hood switch assemblies are generally microswitches and mechanical switches. These switches typically require stepped-down power supply, such as to 5V or 12V, necessitating a power supply circuit. Usually, the power supply circuit is separate from the control circuit within the switch assembly; the power supply circuit is located externally to the range hood and connected later via a power cord. This forces users to install the power supply circuit inside the range hood, causing inconvenience during installation and use. Therefore, further improvement is necessary. To this end, we propose a new range hood switch. Utility Model Content
