The high-efficiency negative pressure filling device, referring to fig. 1 and 2, comprises a sealing element 1, a negative pressure pumping mechanism 2, a filling mechanism 3 and a negative pressure unloading mechanism 4.
Wherein the seal 1 fits into the opening of the container for sealing the container; the seal 1 of the present embodiment is preferably provided in the form of a bottle cap of a container. A connecting pipe 11 is fixed on the sealing member 1, when the sealing member 1 closes the container, the connecting pipe 11 longitudinally penetrates through the sealing member 1, and one end of the connecting pipe extends into the container, and the other end of the connecting pipe extends to the upper part of the sealing member 1.
A rubber packing is provided at a position where the sealing member 1 abuts against the opening of the container to enhance airtightness.
In practical use, 1, 2 or 3 connecting pipes 11 may be provided for connecting the negative pressure pumping mechanism 2, the filling mechanism 3 and the negative pressure discharging mechanism 4 separately or in combination. In order to facilitate the installation and disassembly of a user when necessary, the connecting pipe 11 is connected with the negative pressure pumping mechanism 2, the filling mechanism 3 and the negative pressure unloading mechanism 4 by sleeve joints.

A second valve 32 is mounted on the filling tube 31, and the second valve 32 can control the opening and closing of the filling tube 31, i.e. whether the container is filled with liquid or not. Since the container is under negative pressure, the filling means 3 does not need to be provided with a pump or the like.
Referring to fig. 1, the negative pressure relief mechanism 4 includes a pressure relief pipe 41, one end of the pressure relief pipe 41 is connected to the connection pipe 11 through a ferrule connector, and the other end is communicated with the outside. A first valve 42 is fixed to the pressure relief pipe 41, and the pressure relief pipe 41 is controlled to open, that is, whether or not the pressure in the container is relieved is controlled by the first valve 42.

Because the interior of the container is always in a negative pressure state in the filling work, the liquid can be prevented from foaming and splashing to the opening of the container, and the sealing in the later period is convenient; meanwhile, the filling is carried out under negative pressure, the speed is reduced without considering the foaming problem, and the filling speed is relatively high, namely, the invention can ensure high efficiency and high quality to finish the filling work while avoiding the foaming of the liquid.
Referring to fig. 1, in order to prevent the contaminated air from affecting the product quality or polluting the environment when the contaminated air exists in the container, an air filter 6 is connected to both the air outlet of the vacuum pump 23 and the air inlet of the pressure relief pipe 41 for filtering the air entering and exiting the container.
In order to further improve the working efficiency and facilitate the use of users, the following settings are made, and the invention is converted into automatic equipment.
With reference to fig. 1 and 3, the invention also comprises detection means 7 and control means 8 connected thereto.
The detection mechanism 7 includes a vacuum pressure sensor 71, a flow meter 72, and a sensor 73.
The vacuum pressure sensor 71 is arranged on the sealing member 1, at least a detection end of the vacuum pressure sensor extends to one side of the sealing member 1 facing the inside of the container, and the vacuum pressure sensor is used for detecting and outputting a vacuum pressure detection value; the vacuum pressure sensor 71 is optionally of the type including a digital display screen to accommodate different user requirements.
A flow meter 72 is mounted on the filling pipe 31 between the second valve 32 and the liquid storage tank 33 for detecting a liquid flow rate therethrough and outputting a liquid flow rate value; the flow meter 72 is optionally of the type having a digital display screen to accommodate different user needs.
The sensor 73 may be installed at a side of the container, and a sensor having a position sensing function, such as a distance sensor, is selectively used to sense whether the sealing member 1 is sealed on the container, and output a sensing signal.
The control means 8 comprise a data processing component 81, a memory 82 in data connection therewith, and a timer 83. The data processing component 81 can select a PLC controller, a single chip microcomputer or a microprocessing unit; the timer 83 may be a circuit having timing capability, such as a 555 timer.
The first valve 42, the second valve 32, and the third valve 22 are all solenoid valves. Control mechanism 8 further includes a relay bank 84, relay bank 84 including sub-relays 841 electrically connected to first valve 42, second valve 32, and third valve 22, respectively. The data processing component 81 can control the opening and closing of the first valve 42, the second valve 32 and the third valve 22 through the respective sub-relays 841. The flow meter 72 is connected in parallel to the second valve 32 for control.
The memory 82 is preset with a standard vacuum value, a filling time value or a standard flow value, and a pressure relief time value. The standard vacuum value is set according to the formula: pSetting up＝LLiquid, method for producing the same and use thereof/LBottle (Ref. TM. bottle)-1-PSecurity(ii) a Wherein P isSetting upIs a standard vacuum value; l isLiquid, method for producing the same and use thereofIs the volume of the liquid filled; l isBottle (Ref. TM. bottle)Is the volume of the bottle; 1 represents an atmospheric pressure, represents the conversion into a vacuum mode, and the vacuum value, namely the negative pressure is a negative value; pSecurityFor a safety margin, which is greater than 0, it is essential, as determined in practice, to take into account the internal volume error of the container and the necessary slight underpressure that still needs to be maintained after filling of the liquid.
The control logic of the present invention is referenced in the following table:
the use process comprises the following steps:
when the sensor 73 detects that the sensing signal output to the data processing component 81 indicates that the sealing member 1 seals the container, the data processing component 81 controls the third valve 22 to open, and the vacuum pump 23 is used for vacuumizing the container;
when the vacuum pressure detection value output to the data processing component 81 by the vacuum pressure sensor 71 is equal to the standard vacuum value, the data processing component 81 controls the third valve 22 to close and stop vacuumizing, controls the second valve 32 to open for filling the container, controls the flowmeter 72 to measure, and starts the timer 83 to time;
when the timer 83 counts time and equals to the filling time value, or the liquid flow value output by the flowmeter 72 equals to the standard flow value, the data processing component 81 controls the second valve 32 to close and stop filling, controls the first valve 42 to open for pressure relief, and controls the timer 83 to reset for counting again;
when the timer 83 counts the pressure-relief time value, the data processing module 81 controls the first valve 42 to close to stop the pressure-relief operation. At this time, one filling operation is completed.
Because the automatic control is realized by adopting the detection mechanism 7 and the control mechanism 8, the filling precision and the filling speed are faster.
