The specific embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
Like Fig. 1, shown in Figure 2, the vacuum freshness retaining all-in-one that the utility model provides comprises box body 1 and lid 3, the two upper and lower mutual fastening, and the faying face place of the two is provided with seal ring 2, is respectively equipped with handle 4 on the two sides of box body 1.
Combine Fig. 3, Fig. 4 and Fig. 5 again, lid 3 is formed by top cover 17 and bottom 18 upper and lower clamping, and automatic gas extraction device is arranged in the bottom 18; Automatic gas extraction device comprises air pump 10, pressure difference switch 5 and control circuit board 14; And by battery 28 power supplies that are arranged in bottom 18 or the top cover 17, battery 28 is more piece AAA battery or chargeable battery, and lid 3 is provided with USB interface; USB interface is connected with charging module on the control circuit board; Be used for to the chargeable battery charging, spiral-lock has battery cover 23 on the top cover 17, is used to change battery 28.When voltage is low can not work the time, the battery that need more renew, replaceable No. 7 (AAA) batteries are easy to operate when opening battery cover 23.If what use is rechargeable battery, when voltage is low can not work the time, need not open battery cover, in a USB at battery cover top connect, it was just chargeable directly to insert USB.
The air suctiton inlet of air pump 10 is through flexible pipe 11 connection pipe joints 9, and adaptor union 9 is fixed on the bottom 18 and with box body 1 inner chamber and communicates, and is provided with check valve 7 in the adaptor union 9, when air pump 10 starts, through check valve 7 air-breathing and discharge from the inner chamber of box body 1.
The admission port of pressure difference switch 5 communicates with the inner chamber of box body 1; Pressure difference switch 5 signal output parts are electrically connected to control circuit board 14; Control circuit board 14 is provided with control button 15, and control button 15 upwards passes top cover 17 and battery cover 23, starts the automatic gas extraction device work through control button 15.When difference of pressure during less than pressure difference switch 5 setting values, control circuit board 14 output control signals, booster air pump 10 work; When difference of pressure during more than or equal to the pressure difference switch setting value; Control circuit board 14 output control signals stop air pump 10 work, keep constant voltage in the box body 1 automatically thereby make.
The center of battery cover 23 is provided with pit; Be provided with a disk 24 that is marked with digital 1-31 in the pit; A sheathed indicating device 25 on the disk 24; Through the slip of indicating device 25 on disk 24, can set the date of putting into crisper article food, so that understand the time that stores food intuitively.
The circuit diagram of the utility model control circuit board 14 is as shown in Figure 7, below in conjunction with circuit diagram the principle of work of the utility model control circuit board 14 is explained as follows:
The controllable function of control circuit board 14 is mainly realized by one 8 Programmable Logic Controller.
For the first time press control button 15, then get into the vacuum freshness retaining pattern, at this moment, indicator lamp (dual-colored LED) is shown in green; Whenever dodged at a distance from two seconds, air pump 10 begins to bleed, continuous working after 4 minutes green light can dodge, per second dodges twice; Stop one second, but machine works on still, auto-stop after 6 fens kinds.When the chamber pressure of box body 1 reaches the setting value of pressure difference switch 5; Air pump 10 stopped to bleed after working 10 seconds again; The purpose that setting air pump 10 was worked 10 seconds again is that the negative pressure in the inner chamber of box body 1 is increased again; If gas leakage will wait a period of time after air pressure just can drop to setting value, increased the work that air pump just can not be frequent under the gas leakage situation of this section phase buffer, mainly be to prolong the air pump life-span and save battery electric quantity.
When pressure difference switch 5 detected pressure in box body 1 inner chamber less than setting value, pressure difference switch 5 sent control signal, and booster air pump 10 is bled once more, so repeatedly, keeps the constant voltage in box body 1 inner chamber automatically.
When pressure difference switch 5 detected pressure in box body 1 inner chamber and is 0, air pump 10 began to bleed, continuous working after 4 minutes green light can dodge, per second dodges twice, stops one second, but machine still works on, auto-stop after 6 fens kinds.This design mainly is that uncover is got thing under the state of having forgotten shutdown when considering that the customer uses.If the air pump continuous working surpasses 6 minutes, pressure difference switch 5 does not still send the air pump stop control signal, and crisper gas leakage then is described, at this moment, control circuit board 14 sends alerting signal, and the indicator lamp fast blink is shutdown automatically after 30 seconds.Test according to reality; If crisper is air tight; Air pump 10 can be extracted into the pressure in box body 1 inner chamber preset value of pressure difference switch 5 fully in 2 minutes; So set this time, also do not have action to explain that then crisper has gas leakage if instead surpass 2 minutes baroswitches, at this moment just have the indicator lamp flicker and remind.
The low voltage alarm mode: Programmable Logic Controller detects No. 7 (AAA) batteries in real time provides 4.5V voltage or chargeable source that 3.6V is provided voltage; When voltage was lower than 3.1V, blinking red lamp stopped one second in bright one second, and prompting needs charging; Glimmer and shut down automatically after 30 seconds: as in time not changing battery or charging; When start back Programmable Logic Controller detected voltage and is still 3.1V, then red light still glimmered and stopped one second in bright one second, glimmer to shut down automatically in 30 seconds.
Charge mode:, when chargeable battery voltage is lower than 3.1V, need charging in time only to chargeable battery.Red light Chang Liang during charging, green light Chang Liang when being full of electric 3.6V.
Under any mode of operation, the long control button of pressing shut down after 15 two seconds.
This circuit gets into low-power consumption energy saver mode (to prolong the period of service of internal cell) in standby after two seconds in addition, makes the stand-by power consumption of circuit be reduced to several microamperes.There is the button input to trigger MCU work up to circuit, makes circuit get into mode of operation.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of under the enlightenment of the utility model, making, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the utility model.
