Abstract
A spherical puffing pump for an ice cream machine and an air inlet device thereof. The spherical puffing pump includes a spherical pump body, a clamping plate and an air inlet valve. A liquid feeding hole of the spherical pump body is connected to a milk slurry tank to feed milk slurry. The air inlet valve is connected to a channel of the liquid feeding hole to introduce air. A liquid discharging hole is connected to a liquid inlet of a refrigerating cylinder. A pump seat is fixed on the ice cream machine. An end portion of the pump seat protrudes from an inner wall of the tank. A cylinder of the spherical pump body is connected to the end portion through the clamping plate. A main shaft of the spherical pump body is connected to a motor shaft through a connecting shaft for power transmission.
