A kind of vacuum cup with removable liner
Technical field
The present invention relates to a kind of heat preservation instrument, especially a kind of heat preservation meal cup.
Background technique
There are three types of approach for the propagation of heating power: radiation, convection current and transmitting.In vacuum cup field, usually with applying silver-colored or be coated with
The liner of heat insulating coat reflects radiation of heat, using the transmitting of vacuum or thermal insulation layer blocking heating power between liner and box body, makes
Thermal convection is prevented with the material for being not easy to transmit heat.The vacuum cup with good heat preservation effect all has vacuum layer on the market now
Vacuum cup, but this structure has a kind of defect, and both the junction between cup body and cover was that heat insulation effect is worst
Place, no matter vacuum cup other positions heat insulation effect does good again, and junction heat insulation effect is bad to be also easy to make hot water quick
Lose heat.
Summary of the invention
The present invention aiming at the shortcomings in the prior art, provides a kind of vacuum cup with removable liner, present invention tool
There is the vacuum layer free of discontinuities around cavity volume, the heat transmitting of partition cavity volume that can be comprehensive improves heat insulation effect.Solve with
Toward the bad problem of vacuum cup water outlet heat insulation effect.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals: one kind has in removable
The vacuum cup of gallbladder, including cup body are provided with rim of a cup on the cup body, cavity volume, the cup are provided in the cup body
There is gap between internal side wall and the cavity volume, be vertically arranged with fiberglass pole, the glass in the cup body
It is provided with screw thread on glass fiber rod, thread groove is provided on the cavity volume, is provided in the thread groove and the glass
The opposite screw thread of screw thread on glass fiber rod, the bottom of cup are provided with the knob for controlling the fiberglass pole rotation, institute
Device for fetching water is provided on the rim of a cup stated, the device for fetching water includes the sealing cover of intake and the isolation rim of a cup inner air and outer air,
It is provided with sealing buckle on the cavity volume, the fixing piece of the fixed sealing buckle, institute are provided on the intake
It is additionally provided with the switch for controlling the fixing piece folding on the intake stated, is provided with intake switch on the sealing buckle, institute
The bottom of cup setting air extractor stated, the seam between the air extractor connection cup body inner sidewall and the cavity volume
Gap.
In above-mentioned technical proposal, it is preferred that be provided with seal washer on the knob.
In above-mentioned technical proposal, it is preferred that be provided with sealing ring on the sealing buckle.
In above-mentioned technical proposal, it is preferred that the air extractor includes being connected to the outter box and the inner box
Between gap hand-operating vacuum-pump.
There is gap, both cavity volume " suspension " was in cup body between the cavity volume that the present invention is filled with water and cup body inner sidewall.Hold
It all being connected by fiberglass pole between product chamber and cup body, fiberglass pole is a kind of heat-resist, material of high mechanical strength,
Screw thread is additionally provided on fiberglass pole, cavity volume can be moved up and down according to the screw thread on fiberglass pole.In cup body
There is the vacuum pump of gap area between cup body and cavity volume then can make as long as covering sealing cover when use for bottom
The air between gap is extracted with vacuum pump.Once gap is evacuated, then gap can be considered as a vacuum heat-insulating layer, by
Cavity volume is wrapped in gap is free of discontinuities, this vacuum heat-insulating layer is that comprehensive no dead angle is wrapped by cavity volume, completely every
The hot of hot water of having broken is transmitted, so that heat insulation effect greatly enhances.When drinking hot water, it is only necessary to pass through the screw thread on fiberglass pole
Cavity volume can be allowed to rise identical as intake.But when absorption every time, all there may be poorly sealed phenomenons, then often
It also needs again to vacuumize gap by vacuum pump after secondary absorption.
Compared with prior art, the present invention has the vacuum layer free of discontinuities around cavity volume, the comprehensive partition volume of energy
The heat transmitting of chamber, improves heat insulation effect.Solve the problems, such as that previous vacuum cup water outlet heat insulation effect is bad.

Fig. 2 is that the present invention uses schematic diagram.
Fig. 3 is the place Fig. 1-A of the present invention schematic diagram.
Specific embodiment
Present invention is further described in detail with attached drawing With reference to embodiment.
Embodiment 1: as shown in Figure 1 to Figure 3, a kind of vacuum cup with removable liner, including cup body 1, the cup
It is provided with rim of a cup 3 on body 1, cavity volume 2,1 inner sidewall of cup body and the cavity volume 2 are provided in the cup body 1
Between there is gap 4, be vertically arranged with fiberglass pole 5 in the cup body 1, be provided with spiral shell on the fiberglass pole 5
Line is provided with thread groove on the cavity volume 2, is provided in the thread groove and screw thread phase on the fiberglass pole 5
Pair screw thread, 1 bottom of cup body, which is provided with, controls the knob 51 that the fiberglass pole 5 rotates, on the knob 51
It is provided with seal washer 52.The rotation of fiberglass pole 5 be can control as long as through twisting knob 51 to control the upper of cavity volume 2
Under.Because fiberglass pole 5 is in 2 thread groove of cavity volume, the height that cavity volume 2 declines is defined, so that cavity volume 2 will not
It is contacted with 1 bottom of cup body.Device for fetching water 31 is provided on the rim of a cup 3, the device for fetching water 31 includes intake 33 and isolation
The sealing cover 32 of 3 inner air and outer air of rim of a cup.It is provided with sealing buckle 6 on the cavity volume 2, is set on the intake 33
It is equipped with the fixing piece 34 of contact 63 on the fixed sealing buckle 6, is connected automatically between contact 63 and fixing piece 34.It is described
Intake 33 on be additionally provided with and control the switch 35 that the fixing piece 34 opens and closes, can allow 34 He of fixing piece when using switch 35
Contact 63 separates.It is additionally provided with intake switch 61 on the sealing buckle 6, intake switch 61 is push type, as long as pressing downwards
Pressure, water can be poured out from cavity volume 2, and pressing can close again.It is additionally provided with sealing ring 62 on sealing buckle 6, when sealing blocks
Sealing buckle 6 can seal up intake 33 after button 6 is extend into intake 33.1 bottom of cup body is additionally provided with the connection cup
The hand-operating vacuum-pump 9 in gap 4 between 1 inner sidewall of body and the cavity volume 2.
In use, first opening the sealing cover 32 on device for fetching water 31, cavity volume 2 is moved up by knob 51, when cavity volume 2 is mobile
Contact 63 and fixing piece 34 can connect automatically and cavity volume 2 are fixed when to rim of a cup 3.Intake 33 can be passed through at this time
Work is fetched water and filled the water by the intake switch 61 on means of press seals buckle 6.Then the switch 35 on intake 33 is pressed, allows and connects
Contact element 63 and fixing piece 34 separate, under allowing cavity volume 2 to select by knob 51, the volume when fiberglass pole 5 offsets with thread groove
Chamber 2 slips down to bottom.Subsequently sealing cover 32 is covered behind jail, 1 inner air and outer air of cup body is allowed to completely cut off, gap is extracted by hand-operating vacuum-pump 9
Air in 4, the working method of hand-operating vacuum-pump 9 can be drawing and pulling type either rotary type, more can be used small-sized electronic
Hollow pump is carried out pumping or is evacuated using external vacuum pump.Once the gap between 1 inner sidewall of cup body and cavity volume 2
4 form vacuum or similar hollow environment, then gap 4 can be considered as a vacuum heat-insulating layer, this vacuum heat-insulating layer is
No dead angle it is comprehensive wrap cavity volume 2, can thus can be greatly reduced or prevent the heat transmitting of cavity volume 2.
