Temperature control system for grill, main unit, and fan

A main unit for a temperature control system of a grill, wherein the main unit is configured to be mounted on the grill, a fan is positioned corresponding to an intake port of the grill to adjust an intake volume for controlling fuel combustion, and the main unit and the fan are in communication;

• the main unit comprises a control module and a temperature measurement module, the temperature measurement module is configured to detect an air ambient temperature of the grill and transmit a first temperature signal to the control module,
• wherein the temperature measurement module comprises a first housing, the first housing is equipped with a raised base, and a side wall of the base is equipped with a latch block;
• the control module comprises a second housing, a sliding groove used in cooperation with the latch block is arranged on a side wall of the second housing, the sliding groove comprises an opening and a fixed end, the second housing is positioned within the base, with the latch block aligned with the sliding groove, the latch block enters the sliding groove from the opening, and by rotating the second housing, the latch block slides to the fixed end, locking the second housing with the first housing;
• and rotating the second housing causes the latch block slide out from the opening, thus detaching the second housing from the first housing,
• wherein the temperature measurement module further comprises a first signal reception board arranged inside the first housing, a plurality of first pogo pins connected to the first signal reception board and a first temperature sensor configured to monitor a temperature, one end of the first temperature sensor is fixedly connected to the first housing, the other end of the first temperature sensor is arranged an outer side of the first housing, and the first temperature sensor is electrically connected to the first signal reception board;
• the control module further comprises a plurality of second pogo pins, and after the second housing is locked with the first housing, the second pogo pin abuts against the first pogo pin;
• and the first temperature sensor is made of a platinum resistance material.

A fan for a temperature control system of a grill, wherein the fan is positioned corresponding to an intake port of the grill to adjust an intake volume for controlling fuel combustion, the fan and a main unit are in communication either by wired means or by wireless means;

• the main unit is configured to get an air ambient temperature of the grill and control power of the fan or its on/off state based on the air ambient temperature of the grill,
• wherein the fan comprises a housing and a wireless signal board arranged inside the housing, and the wireless signal board is configured to receive a wireless signal from the main unit,
• wherein the fan further comprises a fan blade arranged inside the housing, the housing is equipped with an accommodating groove, an air duct and an air outlet, and the accommodating groove, the air duct and the air outlet are connected in sequence;
• wherein the fan further comprises a horizontal bar and an elastic member arranged at the air outlet, two ends of the horizontal bar are detachably connected to a side wall at the air outlet, the elastic member is rotatably arranged on the horizontal bar;
• the elastic member comprises two supporting rods and a spring portion, and the two supporting rods have an opening and closing angle between them.
