In another preferred embodiment of the invention as shown in FIG. 13 to 15, also it is additionally arranged every magnetic assembly, it should be every Magnetic assembly includes the antifreeze plate 6 of mobile setting, the antifreeze plate 6 can be pushed between magnetic absorbing mass and lower magnetic absorbing mass or remove with Lid 100 is opened or is attracted in corresponding control.It is this to open box cover control mode every magnetic assembly, compared to above-mentioned electromagnet pole Reversing mode, cost is more cheap, operates also simple and convenient.

Wherein, it is controllably to protrude between upper magnetic absorbing mass and lower magnetic absorbing mass to block or reduce two every the effect of magnetic assembly Magnetic attraction between person, to achieve the purpose that control is uncapped.

It specifically, as shown in figure 13, should include being connected every magnetic button 7 every magnetic button 7 with reset spring every magnetic assembly Antifreeze plate 6 simultaneously can drive antifreeze plate 6 to protrude between upper magnetic absorbing mass and lower magnetic absorbing mass to inhibit magnetic under button press state. It after the opening of lid 100, as shown in figure 15, unclamps after magnetic button 7, is smoothly reset to and is pressed by reset spring every magnetic button 7 State before pressing.

Wherein, antifreeze plate 6 can be inserted between upper and lower magnetic absorbing mass (i.e. the first and second magnetic absorbing mass), but consider in the form of sheets The antifreeze plate 6 of better magnetism isolating effect, diagram is preferably formed to frame structure open at one end, in the button every magnetic button 7 Under pressing state, upper magnetic absorbing mass or lower magnetic absorbing mass are limited in frame structure by completely frame.

Antifreeze plate 6 can be it is any can hinder magnetic or press down magnetic material, usually can be selected for example aluminium, aluminum alloy sheet, Stainless steel sheet material or copper sheet material etc..

Since the needs of lid 100 pivotally open, every magnetic button 7 as case of uncapping, it is preferably provided at pedestal 200, As shown in figs. 13 and 14, lid is touched when can prevent from uncapping in this way, high-temperature steam is avoided to scald one's hand.

It should be noted that magnetic pole is presented under closing lid state to upper magnetic absorbing mass shown in figure 15 and lower magnetic absorbing mass in Figure 13 Attracting state.Upper and lower magnetic absorbing mass can be that any one of permanent magnet or upper magnetic absorbing mass and lower magnetic absorbing mass are permanent magnetism Iron, another one are iron block.Moreover, any one of upper magnetic absorbing mass and lower magnetic absorbing mass can also be electromagnet, such as connection exchange The alternating electromagnet of power supply.Circuit switch 5 can be preferably equipped in the electromagnet circuit of electromagnet, for controlling electromagnet Whether 5 charge.

Referring to Fig. 6, under the closing lid state of lid 100, relative to the pivot hinge joint between lid 100 and pedestal 200 (i.e. hinge joint OO ' is pivoted shown in Figure 16) pivots the reset torque M2 of spring 1 less than the magnetic between magnet 3 and iron core stick 4 The magnetic torque M3 of resultant force and the sum of the center of gravity torque M1 of lid 100.In this way, can uncap the stage anti-, so that locking closure torque Greater than torque of uncapping, realize that lid is self-locking.

Specifically, the magnetic in various specific embodiments, when electromagnet no power, between magnet 3 and iron core stick 4 It is relatively small with joint efforts, but should be able to also realize that lid is self-locking.To ensure the self-locking security reliability of lid, need to propose locking closure torque Surplus design out, such as meet M3- (M2-M1) > 1Nm, the internal pressure etc. that can meet cooking apparatus in this way causes lid to automatically open.

When there are electromagnet circuit, the conductive winding for being wound in iron core stick 4 enhances magnetic adhesion, and conductive electromagnet increases Strong lid self-locking property, can more meet the surplus design of above-mentioned locking closure torque.But in order to improve magnetic induction efficiency, in electromagnet Conduction state under, preferably meet: M3- (M2-M1) < 15Nm extends the electrical part longevity to help to realize the low-power consumption of product Life.

Referring to Fig. 7, the stage of uncapping is needed under closing lid state, can be switched by current reverser and flow through electromagnet Current direction, so that electromagnet generates the repulsion magnetic force relative to magnet 3 to open lid 100.In this situation, when in lid Repulsion magnetic force when the closing lid state and electromagnet conduction of body 100, relative to pivot hinge joint, between magnet 3 and electromagnet Magnetic reprimand torque M4 and pivot spring 1 the sum of reset torque M2 be greater than it is upward in center of gravity the torque M1, i.e. Fig. 7 of lid 100 Torque is greater than downward torque, openable lid 100.

Likewise, need to propose surplus design to torque of uncapping, such as need to meet M4+M2-M1 for the reliability for ensuring to uncap > 1Nm, to prevent, unexpected vibration or collision from causing to uncap or because internal pressure etc. causes lid to automatically open.

To sum up, the present invention devises a kind of novel magnetic locking mechanism for folding lid, can be applied to the production such as electric cooker In product.By the magnet attracting mode of upper and lower magnet, when lid cannot be opened in certain operation sequences (such as washing a meter process) When, it is self-locking lid can be reached by closing lid magnetic mode.When needing to open lid, it is only necessary to for example, by traditional simple push button Mode can quickly reduce magnetic adhesion, guarantee that lid is safely opened, and not will increase too many product cost, and can be hidden It is hidden in lid and pedestal, does not influence product appearance completely.
