A mounting and demounting structure includes a blade hub and multiple fan blades. Multiple mounting seats are disposed on the blade hub along a circumferential direction of the blade hub. The multiple fan blades are connected to the multiple mounting seats respectively. A locking leaf is rotatably connected to each mounting seat. The locking leaf is in a locked state of engaging with the each mounting seat and an unlocked state of disengaging from the each mounting seat.

Mounting and demounting structure and fan

An air guide structure is disposed between an axial flow fan and a heating body. The air guide structure includes a frame body and at least three air guide vanes, and the air guide vanes are arranged in an annular array on the frame body. A curved surface or multiple planar surfaces are provided between an air guide vane leading edge and an air guide vane trailing edge for transition between the air guide vane leading edge and the air guide vane trailing edge, the air guide vane leading edge is parallel to an incoming flow direction of the axial flow fan, and the air guide vane trailing edge is parallel to an air outlet channel of the heating body. A fan heater includes an axial flow fan, a heating body, and the air guide structure.

Air guide structure and fan heater

A cooking control method of a cooking apparatus includes steps of heating a cooking chamber of the cooking apparatus to an ambient temperature by a heating unit of the cooking apparatus, detecting the ambient temperature of the cooking chamber, maintaining the ambient temperature of the cooking chamber, maintaining the ambient temperature of the cooking chamber at a predetermined set temperature by controlling the heating unit when the ambient temperature of the cooking chamber reaches the predetermined set temperature, detecting an inner temperature of an inner portion of the cooking object, and controlling the heating unit to heat the cooking chamber to maintain at an appropriate cooking temperature when the inner temperature of the cooking object reaches the appropriate cooking temperature so as to cook the cooking object at the appropriate cooking temperature in the cooking chamber.

Air fryer and cooking control method therefor

Provided are a control system of an electromagnetic relay and an electromagnetic relay. The control system of an electromagnetic relay includes an electromagnet coil, a first resistor, and a first voltage control element. A first terminal of the electromagnet coil is connected to a first terminal of a first power circuit through the first resistor. A second terminal of the electromagnet coil is connected to a second terminal of the first power circuit. The first voltage control element is connected in parallel to the electromagnet coil. The first voltage control element can control the magnitude of the voltage across the electromagnet coil, so that the force to which armature iron is subjected gradually changes.

Control system of an electromagnetic relay and electromagnetic relay

An air channel arrangement of a tower fan, arranged for accommodating an air blower therein, includes a housing having an air inlet, an air outlet and an air blower installation space therein, a volute shell and a volute member having a curved surface portion, wherein the volute shell and the curved surface portion of the volute member are arranged on two sides of the air outlet respectively such that, when the air blower is driven to rotate, the airflow is guided to flow through the air channel smoothly, so that the tower fan has excellent air supply efficiency and is able to prevent eddy airflow being formed in in the air channel and reduce working noise of the tower fan.

Tower fan and air channel therefor

A power plug includes a shell, an overheating protection module, a first wire, and a second wire. The overheating protection module includes a first pin, a second pin, a thermal circuit breaker, and a protective resistor. The thermal circuit breaker and the protective resistor are connected in parallel. A first end of the protective resistor is connected to one of the first pin or the second pin, and a second end of the protective resistor is connected to one of the first wire or the second wire. When temperature of the thermal circuit breaker is excessive, the thermal circuit breaker is disconnected, current continues to supply power to low-current electrical appliances through the protective resistor.
