A
brewing water
injection device comprises an inner water injection ring hot
water pipe, an outer water injection ring hot
water pipe, a first
electromagnetic valve, a second
electromagnetic valve, a water injection head and a water injection piece. An inner ring hot
water channel and an outer ring hot
water channel are arranged on a water injection head body of the water injection head, a water injection piece is arranged below the water injection head, and a plurality of inner ring water injection holes and a plurality of outer ring water injection holes are formed in the water injection piece. The first
electromagnetic valve and the second electromagnetic valve can be opened independently or jointly, and when the first electromagnetic valve is opened, hot water can be conveyed to the inner ring hot
water channel of the water injection head through the inner water injection ring hot
water pipe, and water is injected downwards through the inner ring water injection hole. When the second electromagnetic valve is opened, hot water can be conveyed to the outer ring hot water channel of the water injection head through the outer water injection ring hot water
pipe, and water is injected downwards through the outer ring water injection hole. Therefore, a manual coffee
brewing procedure can be simulated by a mechanical structure, the structure is simple, and the use
failure rate and the equipment cost can be reduced.
