Abstract: Disclosed are a refrigerant leakage detection method and device, an air conditioner and a storage medium. The method includes: acquiring an exhaust temperature of an air conditioner at various moments during a preset time period, in response to the exhaust temperature of the air conditioner being greater than a preset exhaust temperature and a target operating exhaust parameter of the air conditioner exceeding a preset range of the exhaust parameter of refrigerant leakage; determining an extreme value of the exhaust temperature and an exhaust moment corresponding to the extreme value of the exhaust temperature of the air conditioner based on the exhaust temperature at various moments; acquiring an exhaust period of the air conditioner based on the exhaust moment; and determining whether there is the refrigerant leakage in the air conditioner based on the exhaust period.

Abstract: A swimming pool water valve with a support element, comprising a water valve main body and a support element, wherein the support element and the water valve main body are integrally formed or assembled on the water valve main body, the support element supports the water valve main body, the water valve main body comprises a water inlet, a water outlet and a switch valve, wherein the water inlet is connected with the swimming pool, and the switch valve controls the connection and the separation of the water inlet and the water outlet. The swimming pool water valve is supported by the support element, so as to realize the function of protecting the drainage outlet and the water intake of the swimming pool from being torn and damaged easily and avoiding water leakage, thereby achieving the effect of long-term stable and safe use of the product.

Abstract: A housing includes a first housing and a second housing. The second housing is provided with at least one protrusion, and the first housing includes a bottom wall and a side wall. The side wall is disposed on a peripheral edge of the bottom wall to form an accommodating space together with the bottom wall. The second housing is disposed on a side of the side wall away from the bottom wall, and the at least one protrusion is accommodated in the accommodating space and comes in contact with an inner surface of the side wall.
