1. A snowflake machine comprising:
a base;
a blower module fixed in the base and including a blower having an air outlet, wherein the blower module includes an inner coupling portion and an outer coupling portion located around the inner coupling portion, wherein the inner coupling portion defines an inner air passageway therein, wherein an outer air passageway is defined between the inner coupling portion and the outer coupling portion and is located around the inner air passageway;
an outlet device connected to the outer coupling portion, wherein the outlet device includes a primary passageway and a secondary passageway spaced from the primary passageway, wherein the primary passageway is located between the inner air passageway and the secondary passageway in a radial direction of the inner air passageway, wherein the inner air passageway is located between the primary passageway and the blower in a longitudinal direction of the inner air passageway, and wherein each of the primary passageway and the secondary passageway intercommunicates with the outer air passageway;
a bubble forming cap coupled with the inner coupling portion and spaced from the primary passageway and the secondary passageway;
a storage tank securely disposed in the base and configured to store a bubble liquid; and
a pump securely disposed in the base, wherein the pump delivers the bubble liquid to the bubble forming cap, wherein the blower operates to generate air currents which enter the inner air passageway to cause the bubble forming cap to generate bubbles, wherein the air currents also enter the outer air passageway to pass through the primary passageway and the secondary passageway and move to an outer side of the outlet device, such that a portion of the air currents passes through the primary passageway and pushes the bubbles generated by the bubble forming cap outward, and wherein another portion of the air currents passes through the secondary passageway to prevent the bubbles and the bubble liquid from accumulating in an outlet of the primary passageway and surrounds the bubbles, thereby pushing the bubbles farther away from the outlet device.
