Embodiments of the present application provide a seat ventilation method and device, electronic equipment, storage medium and vehicle. The method comprises: acquiring a seat temperature, and controlling a ventilation mode of the seat according to the seat temperature; wherein the ventilation mode comprises a blowing mode and a suction mode, so that the ventilation mode of the seat is properly selected, and the advantages of the blowing mode and the suction mode are combined, thereby avoiding blowing hot air to a passenger by the seat, switching to the blowing mode in time when cool air can be blown, reducing fan noise, and improving the comfort and driving experience of the seat.

The utility model discloses a cooking utensil which comprises a circuit board assembly and a cooling fan, the cooling fan blows cooling air to the circuit board assembly, the circuit board assembly comprises a support and a circuit board, and the circuit board comprises a substrate and a high-power component fixed on the substrate through pins. Pins of the high-power component are located on the back surface of the substrate, the support comprises a mounting plate used for fixing the circuit board, a patch NTC is further arranged in the area, corresponding to the high-power component, of the back surface of the substrate, and a wind shielding surrounding rib surrounding the outer side of the patch NTC is arranged between the mounting plate and the back surface of the substrate. According to the cooking utensil, the number of parts can be reduced, automatic production of the circuit board can be achieved, the manufacturing cost of products is further reduced, and the temperature accuracy of high-power components can be effectively improved.

The utility model discloses an inflation protection device for welding a metal pipe material, which does not need to be filled with inert gas in advance, can ensure that a welded seam is smooth and flat, and can save gas and improve welding efficiency. The device comprises a main body, an arc groove matched with a pipe material is formed below the main body, and a gas storage groove is formed in the middle of the top face of the arc groove and corresponds to a pipe material gap; the main body is also provided with an inflation channel communicated with the air storage tank; during use, gas flows to the gas storage groove and the arc groove through the inflation channel, and the welding gun is arranged at one end of the gas storage groove to weld a pipe gap.
