The following is a further explanation of the present invention with reference to the accompanying drawings and embodiments.

Specific embodiment

Referring to Fig. 1 and Fig. 2, the vacuum incubator of the present embodiment includes shell 1, outer cover 2, liner 3 and inner cover 4, outer cover 2 with Shell 1 surrounds accommodating chamber 11, and check valve 21 is provided on outer cover 2, and liner 3 is located in accommodating chamber 11, and inner cover 4 is fastened on liner 3 Food holding chamber 31 above and with liner 3 is surrounded, accommodating chamber 11 includes the pumping outside food holding chamber 31 and food holding chamber 31 Room 12, outer cover 2 are abutted with inner cover 4.

Outer cover 2 is equipped with groove 22, and the bottom of groove 22 offers venthole 23, and check valve 21 is located in venthole 23, Groove 22 is connected to by venthole 23 with aspirating chamber 12.The matching used aspiration pump 5 of vacuum incubator with the present embodiment includes Pump bowl 51, pumping handle 52 and sealing ring 53, pumping handle 52 are located in pump bowl 51, and sealing ring 53 is located at pumping handle 52 Between the inner wall of pump bowl 51.The shape of 2 upper groove 22 of outer cover and the shape of the end of pump bowl 51 match.For vacuum guarantor When incubator vacuumizes, the end of pump bowl 51 is placed in the groove 22 on outer cover 2, by extract and press pumping handle 52 come By the air discharge in aspirating chamber 12.

Referring to fig. 2, the inner wall of outer cover 2 is equipped with limiting section 13, and limiting section 13 is along the circumferential from outer cover 2 of outer cover 1 The protrusion that wall extends downwardly, limiting section 13 are abutted with the upper surface of inner cover 4, be provided between limiting section 13 and inner cover 4 first every Thermal part (not shown).Optionally, the first heat insulating member is made of materials such as glass fibres.The main function of first heat insulating member It is to prevent food holding chamber 31 by inner cover 4 and the extraneous hot transmitting of progress, the food being located in food holding chamber 31 is enable to grow Time heat preservation.

It is provided with first seal 24 between outer cover 2 and the upper perimeter wall of shell 1, is set between inner cover 4 and the upper perimeter wall of liner 3 It is equipped with second seal 41.The lower end of outer cover 2 offers the first recess 25, and the outer end of outer cover 2 has the roof from outer cover 2 The extension 27 extended downwardly, the first recess 25 are surrounded jointly by extension 27, limiting section 13 and the roof of outer cover 2, and are limited Portion 13 is the inner sidewall of the first recess 25, and the upper perimeter wall of shell 1 is located in the first recess 25, the interference fit of first seal 24 ground It is arranged in the first recess 25.The lower end of inner cover 4 offers the second recess 42, and the upper perimeter wall of liner 3 is located in the second recess 42, The interference fit of second seal 41 ground is arranged in the second recess 42.Preferably, first seal 24 and second seal 41 are equal It is made of silica gel material.And limiting section 13 is connected to the back of the second recess 42 on inner cover 4, can make in this way limiting section 13 from It is pressed downward on the periphery of the roof of inner cover 4, so that fixed inner cover 4, guarantees good sealing between inner cover 4 and liner 3.

Referring to figs. 2 and 3, vacuum indicator 26, the inside of aspirating chamber 12 and vacuum indicator 26 are additionally provided on outer cover 2 Connection.Preferably, vacuum indicator 26 is a lid made of elastic material, offers mounting groove 14 outside the roof of outer cover 2, It is equipped with positioning column 15 in mounting groove 14, there is gap between mounting groove 14 and positioning column 15, vacuum indicator 26 is fixedly mounted on In the gap.The middle part of positioning column 15 offers centre bore 151, and centre bore 151 is connected to aspirating chamber 12.Under natural conditions, very Empty indicator is to remotely located 15 end side of column protrusion, there is no vacuum indicator 26 when nature refers to not vacuumizing State when by active force.The outer surface of inner cover 4 is provided with handle 43, moves back convenient for hand gripping and puts inner cover 4.

Referring to fig. 4, be provided with the second heat insulating member 16 on the inner wall of shell 1, the second heat insulating member 16 be located at shell 1 with it is interior Between gallbladder 3, and the second heat insulating member 16 is uniformly distributed on the side wall and bottom wall of shell 1.Second heat insulating member 16 is by glass Fiber and other material is made.The main function of second heat insulating member 16 is support liner 3 and heat-insulated effect.

The use step of the vacuum incubator of the utility model is described as follows below.

Firstly, the prepared food such as box lunch are placed in liner 3, inner cover 4 is fastened on liner 3.

Then, the liner 3 equipped with prepared food is put into the accommodating chamber 11 of shell 1, covers outer cover 2, at this time inner cover 4 and outer cover The position contacted between 2 is separated by the first heat insulating member, and the position contacted between liner 3 and shell 1 is by the second heat insulating member 16 It separates.At this point, check valve 21 blocks venthole 23, venthole 23 is in closed state, and vacuum indicator is in raised position.

Finally, the end of aspiration pump 5 is placed in the groove 22 of outer cover 2, pumping handle 52 is extracted and pressed repeatedly, it will Air extraction in aspirating chamber 12, makes aspirating chamber 12 form vacuum state.

When extracting is evacuated handle 52, since the pressure in aspirating chamber 12 is greater than the pressure in pump bowl 51, check valve 21 Venthole 23 can be opened, while the air of aspirating chamber 12 is drawn into aspiration pump 5.When pressing aspiration pump handle 52, due to pressure Strong poor, check valve 21 closes venthole 23 again, while the air in aspiration pump 5 is discharged in air.Extracting pressing repeatedly is taken out Air pump 5 several times after, the air in aspirating chamber 12, which is extracted in rear aspirating chamber 12, forms vacuum state, at this time vacuum indicator 26 Due to pressure difference, can be recessed to close to 15 end side of positioning column.

Therefore food is placed in food holding chamber first, accommodating chamber is placed on after inner cover and liner fastening In, it then will be extracted out in aspirating chamber as the air of heat transmission medium, aspirating chamber made to be in vacuum state, in this way Jie of heat transmitting Matter is without vacuum incubator can realize good heat insulation effect.Outer cover is abutted with inner cover to prevent liner in accommodating chamber It shakes, while pumping chamber pressure after vacuumizing due to aspirating chamber can be prevented to be less than the indoor pressure of food placement and be detached from inner cover Liner, to destroy the vacuum state of aspirating chamber.The vacuum incubator of the utility model is easy to operate, sealing and heat insulation effect It is good, and prepared food can guarantee the quality heat preservation during the transport of relatively long distance.

Finally, it should be noted that the above is only the preferred embodiment of the utility model, but the design structure of the utility model Think of is not limited thereto, and such as vacuum indicator is mounted on the shape of the change of the fixed form covered outside, shell and liner The variations such as change are also each fallen within the protection scope of the utility model.
