Description

One kind Stirling structure cup from

Technical field

The utility model is related to cup field, more particularly to Stirling cup.

Background technology

Although usually used cup species is various, different, vdiverse in function, substantially there are cup lid and cup group Into lacking feeling of freshness.

In order to improve the interest that cup is used, the applicant is improved existing cup, such as Application No. A kind of cup disclosed in 201510383265.9 Chinese patent application, Stirling engine is combined with the cup of cup, is led to Cross hollow out formation " n " shape or " mouth " shape in cup so that Stirling engine unit is located in openwork part, and Stirling Engine can absorb heat from the inwall bottom of hollow out, so as to drive flywheel turns.Thus, using Si Te can also be viewed and admired while cup The flywheel turns of woods engine unit, improve the interest that cup is used.

However, these above-mentioned Stirling engines, generally existing following shortcoming：Exist during flywheel turns dead Point is, it is necessary to which certain force driving could break through this dead point, and this is accomplished by artificially going to apply one section of a starting power or wait Longer time Stirling engine module can be started.One section of longer time is waited easily to wear down the patience of user； When Stirling engine system is in an environment (such as cup), it is impossible to applied by using hand or some other simple mode Plus a starting power, so limit the overall application of Stirling engine module.

In order to solve the above problems, the applicant improves on the basis of Stirling cup again, such as Application No. A kind of cup with the Stirling engine module for being easy to start disclosed in 20162025569.8 Chinese patent, will be in cup It is provided with body, the assistant starting mechanism includes being arranged on the driving machine that can be operated on the cup and on the outside of the cup Structure, and by the drive mechanism drive and drive the actuating mechanism of the flywheel turns.But, this structure need respectively by According to drive mechanism and actuating mechanism, structure is complex, installs more inconvenient, and the installation of assistant starting mechanism can also influence The overall aesthetics of cup.

Therefore how to existing Stirling cup be improved, make its overcome above mentioned problem be this area skill urgently The problem solved.

Utility model content

Main purpose of the present utility model is a kind of design by flywheel gravity center eccentric of offer, flywheel is easily broken through Dead point is rotated, realize Stirling engine module from, and the Stirling structure cup simple in construction from.

To achieve the above objectives, the technical solution adopted in the utility model is：One kind Stirling structure cup from, including Stirling engine module is provided with cup and lid, the lid, the Stirling engine module has flywheel, described Flywheel is rotated by the linkage of crank, rocking bar and power piston, it is characterised in that：The geometric center and center of gravity of the flywheel Not in same point, and the flywheel be in dead point when, the line of the geometric center and the center of gravity is not conllinear with gravity vertical.

Preferably, the distance of the geometric center to the center of gravity is L, the stroke of the power piston is T, L >=T.

Further preferably, T≤L≤10T.

Most preferably, L=6T.

Still further aspect is preferred, when the flywheel is in dead point, the line and gravity of the geometric center and the center of gravity The angle of line is α, 10 °≤α≤70 °.

Most preferably, α=30 °.

Compared with prior art, the utility model has the advantage of：By the bias design of flywheel center of gravity, it is in flywheel During dead-centre position, the trend with rotation all the time, after the shorter time is waited, Stirling engine module can just occur to turn It is dynamic（I.e. from）, without going to stir flywheel turns manually；And only changing the gravity proportioning of flywheel, it is easily real Show and other structures will not be changed, with simple in construction, the low advantage of cost.

Embodiment

Describe to be used to disclose the utility model so that those skilled in the art can realize the utility model below.Retouch below Preferred embodiment in stating is only used as citing, it may occur to persons skilled in the art that other obvious modifications.

As shown in Fig. 1 to 5, the present embodiment includes being provided with Stirling engine on cup 100 and lid 200, lid 200 Module 300, Stirling engine module 300 has flywheel 4, and flywheel is carried out by the linkage of crank 3, rocking bar 2 and power piston 1 Rotate.Itself it is critical that, the geometric center 41 and center of gravity 42 of flywheel 4 be not in same point, and flywheel 4 is when being in dead point, The line of geometric center 41 and center of gravity 42 is not conllinear with gravity vertical.The apparent line when geometric center 41 and center of gravity 42 with again When the line of force is conllinear, dead point more " dead " can be made.Wherein, Stirling engine module 300 uses low temperature Stirling engine.

The distance of geometric center 41 to center of gravity 42 is L, and the stroke of power piston 1 is T, T≤L≤10T.When L is too small, fly The weight of wheel 4 is not enough to provide the driving torque that flywheel 4 breaks through dead point, prevents Stirling engine module 300 from from；Work as L When excessive, flywheel 4, which is rotated, can have larger centrifugal force, cause Stirling engine module 300 to run unstable.

When flywheel 4 is in dead point, the angle of the line and gravity vertical of geometric center 41 and center of gravity 42 is α, 10 °≤α≤ 70°.Likewise, when α is too small, the weight of flywheel 4 is not enough to provide the driving torque that flywheel 4 breaks through dead point, sends out Stirling Motivation module 300 can not be from；When α is excessive, flywheel 4, which is rotated, can have larger centrifugal force, cause Stirling engine mould Block 300 runs unstable.

Obtained by test of many times, as L=6T, α=30 °, the effect from of Stirling engine module 300 is preferable, and And running and comparing is steady.

As shown in figure 4, flywheel 4 is in top dead-centre, now the center of gravity of flywheel 4 is located at the right side of the center line of flywheel 4, then flywheel 4 have the trend rotated clockwise.

As shown in figure 5, flywheel 4 is in bottom dead centre, now the center of gravity of flywheel 4 is located at the left side of the center line of flywheel 4, then flywheel 4 have the trend rotated counterclockwise.

General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification Simply principle of the present utility model, the utility model also has respectively on the premise of the utility model spirit and scope are not departed from Changes and improvements are planted, these changes and improvements are both fallen within the range of claimed the utility model.The utility model requirement Protection domain defined by appended claims and its equivalent.
