Mixing module used for refrigerant providing device

A device for spraying a composition and a refrigerant, the device comprising:

• a cartridge connector configured to receive a cartridge storing the refrigerant;
• a valve fluidically connected to the cartridge connector, the valve configured to control a flow of the refrigerant;
• a refrigerant spray configured to spray the refrigerant;
• a composition storage configured to store the composition;
• a mixer providing a mixing space for the refrigerant and the composition to be mixed therein, the mixer including:
• an inflow hole formed on a first wall of the mixer, the inflow hole configured to receive the composition from the composition storage, and
• an insertion hole formed on a second wall of the mixer, the second wall extending from the first wall in a direction crossing the first wall, the insertion hole configured to receive the refrigerant spray;
• and
• a tube disposed between and configured to fluidically connect the composition storage and the mixer, the composition configured to:
• flow from the composition storage to the mixing space of the mixer through the tube based on negative air pressure formed, by a flow of the refrigerant generated by the refrigerant spray, at the inflow hole of the mixer, and
• be mixed, in the mixing space of the mixer, with the refrigerant sprayed by the refrigerant spray,
• the mixer further including:
• a guide structure arranged in the mixing space of the mixer, the guide structure configured to receive the composition from the composition storage via the inflow hole and guide the composition to be mixed with the refrigerant therealong, the guide structure at least partially vertically overlapping the tube and the composition storage in a side view,
• the guide structure including a first part, the first part comprising:
• an end positioned adjacent to the inflow hole formed in the first wall of the mixer, and
• a body extending from the end in an inclined manner and configured to guide, along a first surface of the body, at least a portion of the composition received from the composition storage via the inflow hole,
• wherein a radial gap is formed between a second surface of the body and the first wall of the mixer facing the first part of the guide structure, the second surface of the body opposing the first surface of the body,
• wherein the guide structure has a height measured from a virtual plane comprising the inflow hole,
• wherein a center of the insertion hole has a height measured from the virtual plane, and
• wherein the height of the guide structure is greater than or equal to the height of the center of the insertion hole.
