Snowflake machine

A snowflake machine comprising:

• a base;
• a blower fixed in the base and including an air outlet;
• an outlet device connected to the blower, wherein the outlet device includes a primary passageway and a secondary passageway spaced from the primary passageway, and wherein each of the primary passageway and the secondary passageway intercommunicates with the air outlet of the blower;
• a bubble forming cap disposed in the primary passageway and intercommunicating with the air outlet;
• 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 to cause the bubble forming cap to generate bubbles, wherein the air currents generated by the blower pass through the primary passageway and the secondary passageway and move to an outer side of the outlet device, thereby pushing the bubbles generated by the bubble forming cap outward, and wherein the air currents pass through the secondary passageway to prevent the bubbles and the bubble liquid from accumulating in an outlet of the primary passageway and to push the bubbles farther away from the outlet device,
• wherein the primary passageway includes a first end remote from the blower and a second end adjacent to the blower, wherein the secondary passageway includes an outlet end adjacent to the first end of the primary passageway and an inlet end adjacent to the second end of the primary passageway, wherein a cross sectional area of the outlet end is greater than a cross sectional area of the first end, such that a velocity of air currents flowing through the outlet end is smaller than a velocity of air currents flowing through the first end,
• wherein the cross sectional area of the first end of the primary passageway is smaller than a cross sectional area of the second end of the primary passageway, wherein a cross sectional area of the inlet end is smaller than a cross sectional area of the outlet end, wherein the secondary passageway further includes an intermediate portion between the outlet end and the inlet end, and wherein a cross sectional area of the intermediate portion is smaller than the cross sectional area of the inlet end, such that high-frequency noises generated by the air currents flowing through the secondary passageway is reduced.

A snowflake machine comprising:

• a base;
• a first casing securely disposed on the base, wherein the first casing includes a chamber, an inner air passageway intercommunicating with the chamber, and an outer air passageway located around the inner air passageway and intercommunicating with the chamber;
• a second casing securely disposed on the base, wherein the second casing includes an outer side and an inner side, wherein the second casing further includes an inner space extending from the inner side toward but spaced from the outer side, wherein the second casing further includes a plurality of slots intercommunicating with the inner space, and wherein the inner side of the second casing is sealingly coupled with the first casing;
• a blower securely disposed between the first casing and the second casing, wherein the blower includes an air inlet located in the inner space and an air outlet located in the chamber;
• an inner muffler securely disposed in the chamber and spaced from the blower, wherein the inner muffler reduces sound resulting from operation of the blower and air currents flowing out of the air outlet;
• an outer muffler permitting passage of air and abutting the outer side of the second casing, wherein the outer muffler reduces sound resulting from the air currents sucked into the air inlet of the blower;
• a bubble forming cap coupled with the inner air passageway of the first casing;
• an outlet device coupled with the outer air passageway of the first casing, wherein the outlet device includes a primary passageway intercommunicating with the outer air passageway, and wherein the bubble forming cap is located in the primary 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 to cause the bubble forming cap to generate bubbles, wherein the air currents generated by the blower further pass through the primary passageway and move to an outer side of the outlet device, thereby pushing the bubbles generated by the bubble forming cap outward.
