Arc convex has different height.According to one embodiment of the application, barrier layer 221-222 may include tool There is the arc convex of at least two different heights.According to one embodiment of the application, the crown height phase with same radius Together.
The arc convex of barrier layer 221-222 further comprises the first group protrusion 221 and second group's protrusion 222.The The raised 222 concyclic hearts of one group protrusion 221 and the second group.First group protrusion 221 and the second group protrusion 222 alternate are set It sets, that is to say, that second group's protrusion 222 is set between the two neighboring unequal first group protrusion 221 of radius;Adjacent two First group's protrusion 221 is set between a unequal second group protrusion 222 of radius.According to one embodiment of the application, First group's protrusion 221 is greater than height of the second group's protrusion 222 relative to backplane level 210 relative to the height of backplane level 210.
According to the difference in height between previously described protrusion, the height of the first group protrusion can be set as 5-8mm, second The height of group's protrusion is 2-4mm.It is 2-4mm, second group's height of projection that first group's height of projection, which can certainly be arranged, For 5-8mm, absolute restriction is not done to the height of protrusion in the application.
According to one embodiment of the application, the center point protrusion can not be done for round boss or round bulge loop, diameter Specific to limit, when commodity are placed on it, the magnetic labels on commodity are difficult to vertical with face.Implemented according to the one of the application Example, the center point round boss or bulge loop diameter are less than 30mm.
According to one embodiment of the application, toppling on bottom plate 200 can also include button (not shown), can be with Adjust the height of the first group protrusion 221 and/or second group's protrusion 222.For example, disappearing after application commodity are put into demagnetizer Magnetic device handles wherein commodity demagnetization.Lower button is further pressed, the height of first group's protrusion 221 is adjusted, changes first group After the difference in height of group protrusion 221 and second group's protrusion 222, second of demagnetization processing is carried out to wherein commodity.
Fig. 3 A, Fig. 3 B are to topple over floor diagram according to another embodiment of the application.As shown in Fig. 3 A, Fig. 3 B, Similar to bottom plate 200 is toppled over shown in Fig. 2A, Fig. 2 B, toppling over bottom plate 300 also includes backplane level 310 and barrier layer 321-325.Obstacle The layer 321-325 number of plies is not limited to shown in figure 5 layers.Barrier layer 321-325 is set to the surface of backplane level 310.
It is different from and topples over bottom plate shown in Fig. 2A, Fig. 2 B, the barrier layer 321-325 for toppling over bottom plate of the present embodiment is arc Group's protrusion, the structure with rotary table or annulus.As shown, barrier layer is convex including first group's protrusion 321, the second group Play 322, third group protrusion 323, the 4th group protrusion 324 and the 5th group's protrusion 325 etc..Each group's protrusion has difference Radius, according to one embodiment of the application, the circular ring structure overall diameter of first group's protrusion 321 is less than the second group protrusion 322 circular ring structure interior diameter.Different group's protrusions according to frustum cone structure diameter from big to small or circular ring structure overall diameter from It is sequentially stacked on backplane level 310 to small sequence greatly, forms stepped ramp type.In stacking process, the center line of all group's protrusions It is overlapped.
According to one embodiment of the application, can also be arranged at the center of backplane level 310 perpendicular to backplane level 310 Hole corresponding with column is respectively set at each group's protrusion center line in column.By each group's protrusion according to frustum cone structure diameter from big Column is sequentially passed through to the sequence of small or circular ring structure overall diameter from big to small, forms stepped ramp type as shown in Figure 3B.
According to another embodiment of the application, barrier layer 321-325 can also be integrated with backplane level 310, such as in number Complete plate is cut on control lathe, forms barrier layer 321-325 shape decorative pattern;Or the one of the mould by setting Molding.Or there can also be other modes to make shape as shown in the figure.
Bottom plate 200 is toppled over reference to shown in Fig. 2A, Fig. 2 B, the height of projection that bottom plate 300 is toppled over shown in Fig. 3 A, Fig. 3 B is The height of 2-10mm, each protrusion can be different.The adjacent protrusion with different-diameter, diameter difference are about 60-120mm.Root According to one embodiment of the application, topple over shown in Fig. 3 A, Fig. 3 B bottom plate include a button (not shown), press by Button can further adjust the difference in height of each barrier layer 321-325.
Fig. 4 A, Fig. 4 B are to topple over bottom plate main view according to another embodiment of the application.As shown in Figure 4 A, according to figure The prompt of 2A, Fig. 2 B, Fig. 3 A, Fig. 3 B, the barrier layer 420 for toppling over bottom plate can also be arranged including wavy shaped configuration.When pop can, When the commodity such as bottled water, can are placed on bottom plate, it is difficult upright, causes angle between magnetic labels and demagnetization face thereon not Equal to 90 degree, to increase demagnetization chance of success.
According to one embodiment of the application, unlimited constant inclination fall bottom plate backplane level 410 be smooth, smooth plate.Such as Shown in Fig. 4 B, backplane level 410 can have waveform etc. and rise and fall by a small margin.Such design can reduce the restriction to material, again It can be with save the cost.Bottom plate is toppled over shown in above each embodiment, and not limit its backplane level smooth.
Fig. 5 is to topple over bottom plate main view according to another embodiment of the application.As shown, backplane level 510 is with before Text is described identical, and details are not described herein again.Barrier layer 520 can be made of elastic material.When pop can, bottled water, canned commodity When etc. being put on barrier layer 520, it is easy to topple over, the magnetic labels on commodity is caused to be not orthogonal to demagnetization face, to increase Demagnetization chance of success.Flexible material elasticity is larger simultaneously, will not make thereon commodity knock it is bad etc..
According to one embodiment of the application, elastic material can be made for rubber, spring, sponge etc..According to the application Another embodiment, elastic material may be that SBS, SIS, SEBS, EPDM, POE, TPE, TPV etc. are made.
Fig. 6 is the demagnetization method flow chart according to one embodiment of the application.As shown in fig. 6, in step 610, demagnetization Device receives commodity.In this step, demagnetizer is demagnetizer as previously described with accommodating chamber.It will be put into demagnetization commodity In the accommodating chamber of demagnetizer.It has been arranged in demagnetizer and has toppled over bottom plate, commodity is placed in run-off the straight when toppling on bottom plate, Jin Ershang The angle not equal to 90 degree is presented in magnetic labels and demagnetization face on product.Demagnetization face is the face in demagnetizer with degaussing gear, It can be the bottom surface of demagnetizer, or the side of demagnetizer.In step 620, demagnetizer is to being placed in commodity demagnetization therein. The magnetism in magnetic labels is eliminated, so that consumer takes commodity out of.
Above-described embodiment is not the limitation to the application only for illustrating that the application is used, in relation to the general of technical field Logical technical staff can also make a variety of changes and modification in the case where not departing from the application range, therefore, all equivalent Technical solution also should belong to scope disclosed in the present application.
