Wherein, the bottom through outer appearance chamber 31 is provided with interior appearance chamber 32 and bullet form shoot needle 33's cross-sectional appearance for bullet type and the diameter of straight section of thick bamboo part is the same with outer appearance chamber 31's aperture, make when bullet form shoot needle 33 takes place to remove the space grow atmospheric pressure reduction of interior appearance chamber 32, make refrigerator door 6 when being opened again, bullet form shoot needle 33 can retract by oneself under the effect of interior appearance chamber 32 low-pressure after bullet form shoot needle 33 loses the contact effect with current-limiting piece 122, bullet form shoot needle 33 is in the state of leaking always when preventing refrigerator door 6 from opening, the condition that the tip of bullet form shoot needle 33 accidentally injured people takes place, the security performance of the device has been improved.
Wherein, the arrangement of the external aperture R1 > the internal aperture R2 > the middle aperture R3 ensures that the internal air pressure and the external area of the air guide hole 10 and the air guide groove 13 are stable if the refrigerator door 6 is in a closed state for a long time, at the moment, the refrigerator door 6 is still in a state difficult to open through the contact effect of the magnetic adhesive tape 11, the bullet-shaped shooting needle 33 and the flow limiting sheet 122, at the moment, the refrigerator door 6 is opened, the space pressure in the negative pressure cavity 72 is increased and acts on the extrusion device 4, the flow limiting performance of the flow limiting sheet 123 is difficult to ensure that the external air enters the air guide hole 10 and the air guide groove 13 and is supplemented into the negative pressure cavity 72, the refrigerator door 6 always has a closing tendency, once the door is automatically closed under the condition of being opened by mistake, the probability of the condition of being opened by mistake is further reduced, and the effect of preventing the device from being opened by mistake is, if need use the refrigerator this moment, the refrigerator door only need open to the biggest angle state, thereby the rubber sheet 42 can contact with the inboard extrusion stripping cut piece in negative pressure chamber 72 and receive the extrusion of arc extrusion pole 41 and improve frictional force and make refrigerator door 6 can not paste tightly with the user because of having the trend of closing always and cause inconvenience and puzzlement in the use to the user this moment, and the degree of opening of refrigerator door 6 reaches the biggest and makes the inside pressure in negative pressure chamber 72 reach the biggest this moment, and under the condition that normal use needs certain time, the gas can be followed current limiting piece 122 and discharged the external world, make the inside atmospheric pressure in negative pressure chamber 72 after the closure can normally reduce, thereby guarantee that locking device 3 and current limiting device 12 can carry out stable work after the closure, the stability of the device has been improved.
Wherein, cup joint in negative pressure device 7's inner chamber through arc extrusion rod 41 activity for arc extrusion rod 41 has played the supporting role to refrigerator door 6, has reduced door-hinge 5 and has born the produced effort to refrigerator door 6, has prolonged door-hinge 5's life.
The using method of the invention is as follows:
when the refrigerator is used for the first time, because the refrigerator door 6 is in a closed state for a long time, the air pressure inside the air guide hole 10 and the air guide groove 13 is the same as the external atmospheric pressure, at this time, the refrigerator door 6 is opened to the maximum degree, at this time, the arc-shaped extrusion rod 41 can be inserted into the deepest part of the air guide hole 72 and generates larger air pressure, the air pressure is transmitted to the flow limiting device 12 through the air guide hole 10 and the air guide groove 13, because the air pressure is too high at this time, the air can flow out of the flow limiting hole 123, the air guide hole 10 and the air guide groove 13 are gradually leveled with the external atmospheric pressure, at this time, the refrigerator door 6 is closed again, the arc-shaped extrusion rod 41 is drawn out from the air guide hole 72 and generates low air pressure, the air pressure is transmitted to the flow limiting device 12 in the same form, and the door closing speed is fast, so that the air is difficult, the outer cavity 31 abuts against the flow limiting hole 123 to open the flow limiting hole 123, and the internal low air pressure acts on the bullet-shaped shooting needle 33 to enable the tip of the bullet-shaped shooting needle 33 to enter the R3 position in the flow limiting hole 123 and to be in contact with the flow limiting piece 122, so that the external force required by opening the door is improved, and the difficulty of opening by mistake by children is improved.
If need open the refrigerator door in the short time after the closure, the effect of the inside negative pressure intensity of air guide hole 10 and air guide groove 13 still exists and can make refrigerator door 6 open automatically, has improved user's experience, and the pressure in content chamber 32 can make bullet form shooting needle 33 retract after refrigerator door 6 opens to still have sufficient stroke to make the inside of 72 form sufficient negative pressure intensity and make locking device 3 work once more when making refrigerator door 6 close once more.
If the refrigerator door is closed for a long time to enable the pressure intensity and the external pressure intensity in the air guide hole 10 and the air guide groove 13 to be in a balanced state, at the moment, the refrigerator door 6 is opened to the maximum degree to enable the rubber sheet 42 to be attached to the extrusion inclined block 8 and generate a large friction force under the extrusion of the arc-shaped extrusion rod 41 to resist the high pressure in the 72, so that the refrigerator door 6 is prevented from being in an automatic closing state to enable the refrigerator door 6 to be always attached to a user to cause inconvenience in use, due to the fact that the air guide hole 10 and the refrigerator door 6 are formally used and located at the maximum opening and closing degree, the air guide hole 10 and the air guide groove 13 have enough time to be balanced with the external air pressure through the flow limiting hole 123, and therefore the effect between the flow limiting.
