[specific embodiment]
A kind of pressure releasing device of soy bean milk making machine; it comprises dismountable pressure releasing device body 1 being loaded in soy bean milk making machine 10; soy bean milk making machine 10 is provided with installing hole 100; described pressure releasing device body 1 is loaded in installing hole 100; in described pressure releasing device body 1, be provided with and be communicated with the inner and extraneous pressure release passage 11 of soy bean milk making machine, between described pressure releasing device body 1 and the installing hole 100 of soy bean milk making machine, be provided with and when soy bean milk making machine internal pressure is greater than predetermined pressure P0, can make pressure releasing device body depart from the safety protection structure 2 of soy bean milk making machine.
Soy bean milk making machine 10 comprises head 200 and staving 300, and installing hole 100 is arranged on head 200, and as shown in Figure 1, installing hole 100 can be arranged on the upper surface of head, also can be arranged on the sidewall of head.Installing hole 100 can also be arranged on staving 300.
Predetermined pressure P0 carries out repeatedly safety experiment according to situations such as the size of soy bean milk making machine and heating to draw.
Installing hole 100 of the present invention is cylindrical hole, pressure releasing device body 1 matches for cylindrical structure with installing hole 100, installing hole 100 can be also that cross section is square, triangle, rhombus etc., pressure releasing device body 1 and installing hole 100 match for cross section be square, triangle, rhombus etc.
The structure of the safety protection structure 2 in the present invention can be: as shown in Figure 2 and Figure 3; the pressure releasing device annular groove 12 that its outer wall that is included in pressure releasing device body 1 is provided with; the inwall of the installing hole 100 of soy bean milk making machine is provided with the body annular groove 101 matching with pressure releasing device annular groove 12, in pressure releasing device annular groove 12 and body annular groove 101, is provided with guard circle 13.The cross section of pressure releasing device annular groove 12 and body annular groove 101 can be semicircle, can be also square, triangle, rhombus etc.Wherein pressure releasing device annular groove 12 and body annular groove 101 can arrange 1-3 bar, upper and lower arrangement.
