Background technique
It is at present Ningbo Taiersi Electronic Industrial Co., Ltd. with the most similar prior art of technical solution of the present invention
Application number：201210112408.9 patent of invention, which has very more technical problems, is listed below：1, vacuum
It spends too low.The patent only has the vacuum degree of negative pressure 15-20KPA, is much unable to reach the requirement of food vacuum freshness retaining；2, because of machine
Tool structure is excessively complicated, the application of especially a large amount of gear assemblies, causes to be easy to be caused by rice card master during rice out
Gas leakage, moreover, should go out rice device applies especially cumbersome, strong influence user experience；3, because of the container of food storing
Main body is using plastic part, and ladle body, using square structure, in the state of negative pressure of vacuum, ladle body is easily deformed,
Once deformation will generate gas leakage.We have carried out prolonged negative pressure of vacuum to the finished product of the patent and have tested, discovery leakage
Gas phenomenon is very frequent, it may be said that is the product to fall flat；4, because product structure main body is plastic part, product itself
Can not have the ability for bearing high vacuum negative pressure；5, product vacuum monitors, and is supervised using two independent vacuum pressure Inductance valves
Control, the Inductance valve are physical structure, and under long-time vacuum environment, the physical structure of Inductance valve can generate deformation, cause product
Damage or monitoring accuracy reduce, this is as obsolete product.Present mainstream vacuum induction valve is highly sensitive electronic induction valve, the valve
It needs to be integrated on circuit board, by the every 0.1 second air pressure amount of being slightly variable of built-in chip sequential monitoring, to carry out data monitoring and fortune
It calculates；6, there is no sterilizing equipment decontaminating apparatus, when food sampling, virus, bacterium in the residual air of exchange, existing potential danger.

The shape of circle 15, bung 1 is circle, and the bottom of 1 inner wall of bung is fixedly connected with ultraviolet ray sterilization bactericidal structure 16, pedestal 3
It being made of ABS plastic, and ladle body 2 is circle, one end that threading part 9 extends to inside ladle body 2 is arranged with silica gel sealing ring 17,
This product structural material be 304 stainless steel materials, for pressure vessel, how the resistance to pressure of pressure container, be to
It closes important.The following are pressure vessel pressure resistance calculation methods, have direct relation, stainless steel with material thickness, product diameter etc.
The pressure that pipe can be born in addition to material difference can bear pressure value it is in different size other than；Outer diameter and wall thickness are also very important
Factor, wall thickness is thicker, and the pressure value that can be born is bigger, such as same outer diameter, and 10 thick stainless steel tubes are just thicker than 5 stainless
The pressure that steel pipe can be born wants high more；In addition, also related with outer diameter, outer diameter is bigger, and the pressure value that can be born is smaller, such as together
The wall thickness of sample, the bigger pressure value that can be born of outer diameter is smaller, and it is as follows that stainless steel tube bears calculation of pressure formula：If bearing pressure
For：P (unit MPa), P=2* wall thickness * (minimum yield strength) * design ratio/outer diameter, our stainless-steel vacuum are fresh-keeping
Bucket design parameter is as follows：One：Wall thickness (0.1mm), two：Outer diameter (250mm), three：SUS304 stainless steel tube minimum yield strength is led to
It crosses known to tabling look-up：Tensile strength sigma b (MPa) >=520, offset yield strength σ 0.2 (MPa) >=205, elongation δ 5 (%) >=40,
Contraction percentage of area ψ (%) >=60, hardness：≤187HB；≤90HRB；≤ 200HV, four：Design ratio：It is usually set to >=0.6,
P=2*0.1*205*0.6/250=0.098 (MPa)=98 (KPa) so is calculated, the negative pressure of vacuum set much larger than us
60KPa, when be initially powered, vacuum degree is lower than -40kPa when, K1 (- 40kPa) normal open, K2 (- 60kPa) is normally opened, makes the 2 feet electricity of IC1
Position acts (Vc2=0) for the low-level comparator (C2) lower than 1/3Vcc (4V), IC1, and the output Vo of IC1 is high level (1),
The 2 foot current potentials for being input to IC2 are higher than 1/3Vcc (4V), and the low-level comparator (C2) of IC2 acts (Vc2=1), the 6 of IC2
When foot current potential is lower than 2/3Vcc (8V, Vc1=1), the output Vo of IC2 is constant, and the output Vo of IC2 is high level (1), relay J1
It disconnects, vacuum pump 4 does not work, and after 3 minutes (TH=1.1R2C=3 minutes), the 6 foot current potentials of IC2 are higher than 2/3Vcc (8V, Vc1
=0), the internal discharge switch transistor T conducting of IC2, the output Vo of IC2 are low level (0), and relay is attracted, and vacuum pump 4 works.
When relay J1 actuation, vacuum pump work, 2 feet of IC1 disconnect over the ground, make the 2 foot current potentials of IC1 higher than 1/
The low-level comparator (C2) of 3Vcc (4V), IC1 act (Vc2=1), in X minutes, since the 6 foot current potentials of IC1 are lower than 2/
3Vcc (8V, R=1) makes the output Vo high level (1) of IC1, and the output Vo of IC2 is low level (0), and relay is attracted, vacuum
Pump work after arriving X minutes, since the 6 foot current potentials of IC1 are higher than 2/3Vcc (8V, R=1), makes the output Vo low level of IC1
(1), the output Vo of IC2 is low level (0), and relay J1 is disconnected, and vacuum pump 4 stops working, when suction is greater than -40kPa
When, K1 is disconnected, and IC1's makes 2 foot current potentials higher than 1/3Vcc (4V), and the low-level comparator (A2) of IC1 acts (S=1), by
It is still below 2/3Vcc (8V, R=1) in 6 feet of IC1 at this time, the output Vo of IC1 is constant, is high level (1), when suction is big
When -60kPa, K2 is connected, and the 6 foot current potentials of IC1 is made to be higher than 2/3Vcc (8V, R=0), and the internal discharge switch transistor T of IC1 is connected,
The output Vo of IC1 is low level (0), is input to 2 feet of IC2, since 2 feet of IC2 at this time are low level.The output of IC2 is height
Current potential relay disconnects, and vacuum pump 4 does not work, as described in table 1-2.

The invention also discloses a kind of control methods of automatic vacuum food fresh keeping device, specifically include following steps：
S1, the silica-gel pressure release valve 17 being first gently moved by hand on bung 1, allow equipment inner and outer air pressure moment to reach unanimously, this
When can rotate bung 1 counterclockwise, bung 1 is opened, if equipment can be in high negative pressure vacuum state, bucket without pressure release
Lid 1 can not be opened with manpower, at this moment, can arbitrarily pick and place food, after the completion of food picks and places, then lid shut, used hand
1 handle of bung is held, by the coincideing with ladle body 2 gently of bung 1, bung 1 is rotated clockwise, bung 1 is slowly obtained and ladle body 2 is twisted
Tightly；
S2, do not have to press power key at this time, equipment can start automatically evacuation after bung 1 is opened 3 minutes, for the first time
When booting, because equipment is in non-vacuum, indicator light red light length is bright at this time.So program can be opened in power switch
Starting vacuumizes vacuum pump 4 automatically at that moment, and when equipment vacuum degree reaches preset -40KPA, indicator light is green at this time
Lamp length is bright, and still, evacuation is still working on, when vacuum degree reaches -60KPA in ladle body 2, vacuum pump
4 stop working, and indicator light green light is still grown bright at this time；
