Abstract
A kind of automatic vacuum-pumping apparatus of vacuum fresh-keeping device, pumping panel opposite shell is sprung up and down, when the article wait vacuumize being placed on pumping through-hole, the gravity of article pushes pumping panel, pumping panel is set to move down simultaneously touch-sensitive device, signal is passed to electric-controlled plate after sensing by sensing device, electric-controlled plate controls air extractor starting, air extractor is evacuated vacuum chamber by pump-line, because suction causes the silica gel valve being evacuated on panel deformation, make the pumping through-hole exposure that sealing is blocked by it, air extractor then carries out a cycle to article inside through pumping through-hole and vacuumizes, after vacuumizing, pumping panel is no longer pressurized, external electric-controlled plate control air extractor stops working, air extractor restores atmospheric pressure state, after air extractor restores atmospheric pressure state, atmosphere in vacuum chamber and in air extractor Pressure condition forms pressure difference, so that silica gel valve is again sealed off pumping through-hole, realizes the operation of the automatic vacuum of sack sewing machine.
Description
Technical field
The utility model relates to vacuum fresh-keeping devices, the in particular to automatic vacuum-pumping apparatus of vacuum fresh-keeping device.
Background technique
In vacuum freshness retaining industry, sealing sealing is carried out again after usually vacuumizing to packing box or packaging bag, with true
The food protected in packing box or packaging bag can be fresh-keeping.Existing vacuum fresh-keeping device is separated with vaccum-pumping equipment, benefit inconvenient for use,
And also manual switch is needed to be evacuated when vacuumizing, cause user to need one-handed performance, further causes using not convenient enough.
Utility model content
The utility model be intended to provide one kind can automatic vacuum and vacuum pumping and sealing operation it is unseparated true
The automatic vacuum-pumping apparatus of empty fresh-keeping device.
A kind of automatic vacuum-pumping apparatus of vacuum fresh-keeping device described in the utility model, including the shell with opening, outside
The opening of shell be provided with can the pumping panel that springs up and down of opposite shell, inside the shell and in pumping below the panel be provided with
The sensing device of external automatically controlled partitioned signal connection, is provided with the vacuum chamber surrounded with pumping panel bottom surface, in vacuum inside the shell
It is intracavitary and in pumping panel on be provided with pumping through-hole and in its natural state will be evacuated through-hole sealing silica gel valve；Outside
Shell side is provided with air extractor, and the air extractor is connected by the vacuum chamber extending into pump-line and shell in shell
It is logical.
The automatic vacuum-pumping apparatus of a kind of vacuum fresh-keeping device described in the utility model, since pumping panel can opposite shell
It springs up and down, therefore, when on the pumping through-hole being placed on the article for needing to vacuumize on pumping panel, because of the gravity of article
(or manual depression) is evacuated panel, causes pumping panel to move down simultaneously touch-sensitive device, sensing device and passes signal after sensing
Electric-controlled plate is passed, electric-controlled plate then controls air extractor starting, and air extractor is evacuated vacuum chamber by pump-line, because inhaling
Power effect causes the silica gel valve being evacuated on panel deformation, to make the pumping through-hole exposure for being blocked sealing by it, air extractor
A cycle then is carried out to article inside through pumping through-hole to vacuumize, and in after vacuumizing of a cycle of progress, is taken out
Gas panel is no longer pressurized, and external electric-controlled plate control air extractor stops working, and subsequent air extractor restores atmospheric pressure state, is taking out
After device of air restores atmospheric pressure state, because forming pressure difference with the atmospheric pressure state in air extractor in vacuum chamber, so that silica gel
Valve is again sealed off the pumping through-hole on pumping panel, so that vacuum chamber is in vacuum state, realizes the automatic pumping of sack sewing machine
The operation of vacuum, simultaneously as automatic vacuum-pumping apparatus is set in vacuum fresh-keeping device, therefore, after vacuumizing
Realize sealing, thus make article (such as packing box or packaging bag) vacuumize and sealing operation is high-efficient, more convenient, practicability
It is strong firm.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
A kind of automatic vacuum-pumping apparatus of vacuum fresh-keeping device, as shown in Figure 1, including the shell 1 with opening, in shell 1
Opening be provided with can the pumping panel 2 that springs up and down of opposite shell 1, be provided in shell 1 and below pumping panel 2 with
The sensing device 4 of external 3 signal communication of electric-controlled plate is provided with the vacuum chamber 5 surrounded with pumping 2 bottom surface of panel in shell 1, in
In vacuum chamber 5 and in the silica gel for being provided with pumping through-hole 6 on pumping panel 2 and in its natural state sealing pumping through-hole 6
Valve 7；1 side of shell is provided with air extractor 8, the air extractor 8 by the pump-line 9 that extend into shell 1 with
Vacuum chamber 5 in shell 1 is connected to.The sensing device 4, air extractor 8 are the prior art.It should be noted that being not necessarily to
When sealing, automatic vacuum structure can also independently of sack sewing machine and separately from, only realize automatic vacuum function
Can, convenient for individually being vacuumized to packing box and other items.It is provided at least one spring 10 in shell 1, the one of the spring 10
End be evacuated 2 bottom surface of panel connect, the other end is connect with 1 inner bottom surface of shell, the number of spring 10 have one, two, three,
It four or five etc., arranges according to actual needs.Pumping 2 opposite shell 1 of panel is realized by the elastic force effect of spring 10
It springs up and down.
It is provided with groove type plate 11 in shell 1 and in being evacuated on 2 bottom surface of panel, the groove body of the trough plate 11 and pumping face
Plate 2 surrounds vacuum chamber 5, and through-hole 12 is provided on the groove body bottom surface of trough plate 11, and pump-line 9 extend into one in shell 1
It holds at the through-hole 12 being connected on trough plate 11.
The junction of the trough plate 11 and pumping panel 2 is provided with sealing ring 13, is further effectively ensured in vacuum chamber 5
Vacuum state.
The section of the silica gel valve 7 is in inverted T shaped, the horizontal component abutting pumping panel 2 and nature of the silica gel valve 7
