According to the confluence disc, the ratio D2 / D1 between the diameter D2 of the cylindrical surface where the outer surface of the welding section is located and the diameter D1 of the disc body meets the condition that D2 / D1 is larger than or equal to 1 and smaller than or equal to 10, so that the size of a gap formed between the welding part and the inner peripheral wall of the shell can be increased; therefore, the electrolyte locally accumulated in the rolling groove area has larger space and chance to be communicated with the electrolyte at other positions in the shell, reverse flowing is realized, the electrolyte is prevented from being accumulated in the rolling groove, corrosion to a nickel layer of the battery shell is reduced, and the service life of the battery is prolonged.

The ironing equipment comprises a water tank, an evaporator, a control valve and a booster pump, when a temperature sensing piece monitors that the temperature of the evaporator is higher than or equal to a T value, a signal receiving piece receives a temperature signal fed back by the temperature sensing piece, the control valve is opened, the booster pump is started to supply water in the water tank to the evaporator along a pipeline A, and the water in the evaporator is supplied to the evaporator; the evaporator evaporates liquid supplied by the water tank and sprays water to iron clothes; when the temperature sensing piece monitors that the value of the evaporator is smaller than T, the control valve closes water supply in the water tank, the booster pump continues to work, residual water in the pipeline a is supplied to the evaporator, residual heat of the evaporator evaporates the residual water in the pipeline a, and therefore water is prevented from being accumulated in the evaporator, and when a product is used next time after being powered off, the product is not damaged. If the temperature of the evaporator does not reach the T value, no water is sprayed out of the evaporator, and the safety performance of the ironing equipment is improved.

This application relates to an air conditioning control module, an air conditioning system, and a control method. The air conditioning control module is connected to both an indoor unit module and an outdoor unit module. The air conditioning control module includes a main circuit unit and a circulation unit. The main circuit unit is connected between the indoor unit module and the outdoor unit module, and the circulation unit is connected between the liquid pipe and the gas pipe of the outdoor unit module. Specifically: the main circuit unit is used to disconnect the connection between the indoor unit module and the outdoor unit module when the indoor unit module stops in heating mode; the circulation unit is used to maintain the connection between the liquid pipe and the gas pipe of the outdoor unit module. By disconnecting the connection between the indoor unit module and the outdoor unit module when the indoor unit module stops, the main circuit unit prevents refrigerant from entering the indoor unit module and causing heat loss. Simultaneously, by maintaining the connection between the liquid pipe and the gas pipe of the outdoor unit module through the circulation unit, the refrigerant in the pipes continues to circulate, preventing refrigerant accumulation and thus avoiding heat loss.
