Abstract: A structure to connect a refrigerant pipe and an air conditioner having the same, the connecting structure enabling a refrigerant pipe to be easily connected to an indoor unit or an outdoor unit of an air conditioner and including a refrigerant pipe through which refrigerant flows, a socket part connected to one end of the refrigerant pipe, and a coupling nut coupled to an outer circumferential surface of the socket part, wherein, a socket part is provided with a grip-ring allowing the refrigerant pipe to move in a first direction in which the refrigerant pipe is coupled to the socket part and preventing the refrigerant pipe from moving in a second direction in which the refrigerant pipe is separated from the socket part, and at least one O-ring configured to prevent refrigerant from leaking at the socket part.

Abstract: The present invention relates to a sprayer. The sprayer according to the present invention comprises: a vessel main body where an air intake port and a mist discharge port are formed; a spray nozzle which has an air inlet and a liquid inlet, and which is disposed inside the vessel main body; and an atomization member which collides with or diverts mist sprayed through the spray nozzle. The present invention is capable of effectively atomizing a disinfectant, pesticide, or an environment improving agent such as an air freshener or a deodorant agent in a fine particle state, and is thus economically feasible and environmentally friendly since the possibility of pollution can be reduced.
