Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model proposes a kind of integrated electric heating pot, as depicted in figs. 1 and 2, comprise lid 1, pot body 2 and torsion spring 3, described lid 1 and pot body 2 are hinged by hinge axis 4, described torsion spring 3 has the main spire 31 that is set on hinge axis 4 and by the main spire 31 each extended arm of forces in two ends, fixed arm 33 is arranged on pot body 2, lever arm 34 is arranged on lid 1, in the time of opening cover 1, pot body 2 one end torsion spring arm of forces maintain static, and the torsion spring arm of force of lid 1 one end rotates and drives lid 1 to flick centered by hinge axis 4.Due to the appearance that acts frequently of the folding lid of electric food warmer, in order to reduce the deflection of tired weak spot, improve the service life of torsion spring 3, lever arm 34 described in the utility model is reeled and is formed at least one secondary spire 32, and described secondary spire 32 is formed between the both ends of lever arm 34.
As shown in Figure 3, described torsion spring 3 is to be reeled and formed by a wire, and certainly, the material of torsion spring 3 can be also alloy.Described main spire 31 is identical with the coiling direction of secondary spire 32, that is to say, in the time that main spire 31 is counterclockwise coiling, secondary spire 32 is also counterclockwise coiling; In the time that main spire 31 is clockwise coiling, secondary spire 32 is also clockwise coiling.Described main spire 31 is reeled along its central shaft C1, secondary spire 32 is reeled along its central shaft C2, when the central shaft C1 of described main spire 31 and the central shaft C2 of described secondary spire 32 are when parallel, main spire 31 is identical with the elastic force direction that secondary spire 32 produces, and the screen resilience of torsion spring 3 is maximum.
In the time that the lid 1 of electric food warmer fastens with pot body 2, the bending load that described torsion spring material bears and tensile load maximum, inventor is provided with kink 35 on lever arm 34, described kink 35 is between described main spire 31 and secondary spire 32, the bending angle of described kink 35 is between 130 °～150 °, lever arm 34 is carried out to pre-bending processing, can reduce the helix of the main spire 31 of torsion spring and the deflection of lever arm 34 transition positions, improve the service life of torsion spring 3.
In order to ensure the steady and smooth of folding lid, can be contrary at the coiling direction of the secondary spire 32 of a hinge axis 4 each sheathed torsion spring 3, two torsion springs in two ends, certainly, if there are enough assembly spaces, many group torsion springs 3 can be set or only in electric food warmer hinge axis 4 centers, a torsion spring 3 be set.
Be main forced section and force section because main spire 31 is set on hinge axis 4, the deflection bearing is larger, and secondary spire 32 can rotate along with the rotation of lever arm 34, the not main spire 31 of deflection that secondary spire bears is large, and the deflection size how many coiling number of turns of torsion spring spire 32 can bear to it is directly proportional, the torsion spring elastic force providing with it is inversely proportional to, comprehensive above factor, the utility model is made as the coiling number of turns of main described torsion spring spire 31 the coiling number of turns that is not less than secondary spire 32.Draw through research staff's experimental verification, for integrated electric heating pot as electric pressure pot, electric cooker etc., at the described hinge axis 4 each sheathed torsion springs 3 in two ends, in the contrary situation of secondary spire 32 coiling directions of two torsion springs 3, while selecting torsion spring filament diameter to be 2～2.5mm, the coiling number of turns of main spire 31 is greater than 5 circles, can meet electric food warmer assembling and the requirement in service life.Carrying out 3 design parameters whens design of torsion spring, do not limit to and above-described design parameter, need consider torsion spring silk material and matching requirements etc., anyly comprise aforementioned every described torsion spring feature, all in protection domain of the present utility model.
When the lever arm 34 of torsion spring 3 drives lid 1 in the time that hinge axis 4 rotates, lever arm 34 has relative displacement with lid 1, is provided with Access Division 61 on lid 1, in the present embodiment, described Access Division 61 is a draw-in groove, and in other embodiment of the present utility model, described Access Division can also be hole clipping.Described lever arm 34 is installed in draw-in groove 61 away from one end of main spire 31, and lever arm 34 can move in draw-in groove 61, and described pot body 2 sidewalls are positioned at hinge axis 4 belows and are provided with the hole clipping 5 that fixed arm 33 is installed.When electric food warmer is under closing lid state, torsion spring 3 stores larger elastic force, the fixed structure of the fixing torsion spring arm of force need have good intensity, to prevent the problem of fixed structure fracture, for the draw-in groove 61 arranging on the hole clipping 5 on pot body 2 sidewalls and lid 1, can increase its intensity by increasing wall thickness; Also can adopt on lid 1 and fix a metallic plate 6 by screw, metallic plate 6 upper punches cut draw-in groove 61, and lever arm 34 is installed in draw-in groove 61, have both facilitated torsion spring 3 dismounting, and assembling intensity also can ensure.Certainly the fixed form of torsion spring 3 is various, any described torsion spring 3 is fixed on to mode on electric food warmer all in the utility model protection domain.
At closing lid state, lever arm 34 is owing to being subject to the effect of screen resilience, to be resisted against completely in draw-in groove 61, in the time that lid 1 is opened, lever arm 34 moves relative to draw-in groove 61, and mobile process need overcome larger frictional force, all can there are wearing and tearing in various degree with draw-in groove 61 in lever arm 34 now, in the present embodiment, on lever arm 34, be arranged with wear-resistant sleeve (not shown on figure), casing inner diameter is greater than spring wire diameter, and sleeve pipe can freely move on lever arm 34.Described sleeve pipe is preferably Teflon sleeve pipe, and it has lower coefficient of friction, is a kind of very excellent self-lubricating material, and not variation with temperature and changing of coefficient of friction.Furtulon sleeve pipe box is contained in to lever arm 34 places, can greatly reduces the wearing and tearing between lever arm 34 and draw-in groove 61, be also very easily as needed more casing replacing simultaneously.
The above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
