The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As depicted in figs. 1 and 2, be the uncap electric cooker schematic diagram of safety guard of having of one of them implementation column of the utility model.Electric cooker mainly is comprised of cover assembly and base 3, and wherein, cover assembly comprises control panel 1, cover 2, cover stiffener 4, pushing block briquetting 5, magnetic valve briquetting 6 and inner cap 21.
As shown in Figure 3, Figure 4, the safety guard of uncapping comprises electromagnetic valve component, pushing block assembly, float assembly, draw-in groove spare 13 and ball valve seat silica gel spare 14.
Wherein, electromagnetic valve component comprises magnetic valve 12-1, magnetic valve push rod 12-2 and magnetic valve push rod spring 12-3, its as an integral installation on inner cap 21, magnetic valve push rod 12-2 can carry out free-extension under the elastic force effect of magnetic valve spring 12-3, and its small end contacts with pushing block 11-1, large end sticks in the draw-in groove 13,13 guiding of draw-in groove and fixation, magnetic valve 12-1 is fixed by magnetic valve briquetting 6,6 of magnetic valve briquettings rely on screw to position, compaction solenoid valve further shakes when avoiding the magnetic valve action or breaks away from inner cap 21.
The pushing block assembly comprises pushing block 11-1 and pushing block spring 11-2, wherein, pushing block 11-1 can reciprocating action under magnetic valve push rod 12-2 and pushing block spring 11-2 effect, be designed with pushing block briquetting 5 on it, avoid pushing block 11-1 and pushing block spring 11-2 when action, break away from inner cap 21, pushing block briquetting 5 is undertaken spacing fastening by screw.
Be designed with the chamber seat 11a that holds flexible member on the pushing block 11-1 and be positioned at chamber seat 11a outer and can stop the stopper section 11b that the buckle 10 of uncapping is opened, wherein, pushing block briquetting 5 has the gear tongue 5a that stretches in the seat of chamber.
Preferably, pushing block spring 11-2 is clamped on the gear tongue 5a, at this moment, not only there is spring on the right side of gear tongue 5a shown in Figure 7, and also there is one section spring (end) in the left side of gear tongue 5a shown in Figure 7, but this section spring only plays the effect of clamping gear tongue 5a.
Also be designed with pushing block projection 11-3 and float slot 11-4 on the pushing block 11-1, pushing block projection 11-3 forms spring base, is used for pushing block spring 11-2 and supports thereon, positions guiding, and the other end of pushing block spring 11-2 connects with gear tongue 5a.
Float slot 11-4 is float 18 extending ports, stretches out for float 18, hinders pushing block 11-1 and replys mobile to the ball valve seat direction.Float slot 11-4 is preferably bellmouth, and float 18 has the conical nose suitable with bellmouth.When not having pressure in electric cooker, under the effect of pushing block spring 11-2 restoring force, the float slot 11-4 of pushing block 11-1 can promote float 18 to the motion of electric cooker internal direction, the locking that float 18 is removed pushing block 11-1.
Wherein, the large end of magnetic valve push rod 12-2 and draw-in groove spare 13 pegged graft and cooperated, simultaneously under the effect of the guide part 6a of magnetic valve briquetting 6, but draw-in groove spare 13 linear reciprocation move, the magnetic valve push rod is moved more steady and accurate.
14 selections of ball valve seat silica gel spare are silica gel, substantially are the cap shape, and the interior steam that can prevent from stewing leaks, and plays sealing function.Further, draw-in groove spare 13 stretches in the ball valve seat silica gel spare 14, because silica gel has elasticity, draw-in groove spare 13 is expanding-contracting action within it.
As shown in Figure 3, also be designed with steam valve port 8, ball valve seat 7 on the inner cap 21, and the rotating shaft 9 of uncapping passes the buckle 10 of uncapping and be installed on the inner cap 21, further, the buckle 10 of uncapping can get around and cover rotating shaft 9 and rotate, and reaches the purpose of uncapping and fastening.
As shown in Figure 4 and Figure 5, be placed with briquetting 15 in the ball valve seat 7, further, be designed with exhaust outlet 16 under the briquetting, further, the exhaust outlet below is designed with block-resistant lid 17, prevents that to a certain extent the food such as Rice ﹠ peanut milk from boiling over, and blocks exhaust outlet.
When magnetic valve worked, as shown in Figure 4 and Figure 5, for moving one: the user can uncap; Figure 6 shows that action two: the user can not uncap, and float place partial enlarged drawing as shown in Figure 7.The below sets forth above-mentioned two actions, and the operating state when being magnetic valve and can working.
When magnetic valve was switched on, as shown in Figure 4, magnetic valve push rod 12-2 overcame magnetic valve spring 12-3 active force, toward the buckle 10 directions action of uncapping, the magnetic valve push rod promotes pushing block 11-1, and pushing block overcomes the active force of pushing block spring 11-2, and Compress Spring is toward the buckle 10 directions action of uncapping, the pushing block external part stretches into buckle 10 belows of uncapping, as shown in Figure 6, the buckle 10 of uncapping this moment is propped up by pushing block 11-1 owing to the bottom, without spin the space, can not get around and cover rotating shaft 9 and be rotated, can't uncap.At this moment, briquetting 15 is blocked exhaust outlet 16, has certain pressure in pot.
When magnetic valve cuts off the power supply, as shown in Figure 4 and Figure 5, magnetic valve push rod 12-2 moves toward ball valve seat 7 directions under the effect of magnetic valve spring 12-3 restoring force, simultaneously, pushing block 11-1 toward the action of ball valve seat 7 directions, promotes magnetic valve push rod 12-2 action further under the restoring force effect of pushing block spring 11-2, further by draw-in groove spare 13 and ball valve seat silica gel spare 14, briquetting 15 is pushed away exhaust outlet 16, leaked steam, pot internal gas pressure equates with atmospheric value.At this moment, pushing block 11-1 is separated from cover latch 10 belows, abdicates revolution space, and the buckle 10 of uncapping can get around and cover rotating shaft 9 and rotate, and reaches the purpose of uncapping.
Further, there are following special circumstances.
Exhaust outlet is blocked by other food dregs such as Rice ﹠ peanut milks, and magnetic valve 12-1 is because programme-control reaches the actuation time of cutting off the power supply, at this moment, although briquetting 15 breaks away from exhaust outlet 16 but still has operating pressure in pot, because pushing block 11-1 does not have the active force of magnetic valve push rod 12-2, to pushing block will be separated from below the cover latch 10, the buckle 10 of uncapping can get around and cover rotating shaft 9 rotations, has potential safety hazard this moment---and exist the pressure user to uncap in pot.
For fear of above-mentioned situation, designed float assembly as shown in Figure 7.This float assembly comprises the elastic seal cap 20 of float 18, float-controlled valve cover plate 19 and induced electricity rice cooker internal pressure, and elastic seal cap 20 is installed on the float-controlled valve cover plate 19, and wherein, float 18 remains in the elastic seal cap 20, moves up and down synchronously with elastic seal cap.
When having pressure in pot, float 18 can be under the effect of upwarding pressure, and up a mobile section moves, pass float slot 11-4 place, show such as Fig. 8, withstand pushing block 11-1, stop it toward the action of ball valve seat 7 directions, be separated from cover latch 10 lower ends, cause the user to uncap.Wherein, the action of elastic seal cap 20 induced electricity rice cooker internal pressures also seals simultaneously, prevents steam leakage.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
