Road flows back, and prevents thin rice gruel from blocking steam valve, while is also convenient for steam valve cleaning.
In any of the above-described technical solution, it is preferable that reflux valve rod 102 is food-grade plastic parts；Cap body 106 is sealed as food
Grade silica gel part.
In the technical scheme, food-grade plastic parts is set as by the valve rod 102 that will flow back, is conducive to return valve 10 and subtracts
Weight, food grade silicone part is set as by that will seal cap body 106, according to the elastic property of silica gel part, further lift-off seal effect
Fruit.
