Description
Technical field
The utility model relates to the non-automatic pressure relief device that resets of a kind of electric pressure cooking saucepan, belongs to the technological improvement field of electric pressure cooking saucepan pressure security.
Background technology
What existing electric pressure cooking saucepan generally adopted is elastic construction, produce displacement through the elastomer compressive deformation and come the driving pressure switch to cut off the electricity supply, and steady operation pressure, but pressure switch is can be automatically reset; When pressure switch lost efficacy, then to protect through the pressure limiting device pressure release, the passage of pressure limiting device is narrow ductway, is easy to stop up and loses efficacy; When above two safeguard measures all lost efficacy; Last just rely on the sealing ring pressure relief device and do last safeguard protection, but the sealing ring pressure relief device also can only discharge most of pressure, and can reset once more and boost; Can not thoroughly discharge all pressure, still there is certain potential safety hazard in the consumer.
Summary of the invention
The purpose of the utility model is, for the deficiency that overcomes above-mentioned prior art provides a kind of electric pressure cooking saucepan the non-automatic pressure relief device that resets, thoroughly solves electric pressure cooking saucepan pressure and the potential safety hazard when unusual occurs.
For realizing above-mentioned purpose; The technical scheme of the utility model is: the non-automatic pressure relief device that resets of a kind of electric pressure cooking saucepan; Comprise rigid clip (10), following elastic clip (11), flashing switch (12), it is characterized in that, also comprise drive screw (3), magnet (6), magnetic screw (7); Wherein magnet (6) is installed in down elastic clip (11) end, and magnetic screw (7) is installed in rigid clip (10) end and corresponding up and down with magnet (6).
When the utility model uses, it is installed on electric pressure cooking saucepan stay-warm case (9) the outer wall switch bracket (1), arranged side by side with original pressure switch (14), but its when breaking off corresponding pot inner pressure be greater than original pressure switch corresponding pot inner pressure when breaking off.
Further, said magnet (6) is installed in down elastic clip (11) end through magnetic receiver (5).
Further, said upward rigid clip (10) and following elastic clip (11) all are sheet metal.
Further, said going up on the rigid clip (10) has circular hole (13), with the drive screw that is installed in down (11) on the elastic clip (3) on same center line, the diameter of said circular hole (13) is greater than the diameter of drive screw (3).
Be convenient size of regulating the distance of drive screw (3) with the change setting pressure, said drive screw (3) is locked by two locking nuts (4) on the two sides of following elastic clip (11).The position that changes locking nut (4) promptly can change the setting value of pressure.
Further, the external form of said magnet (6) can be cylinder or square or cuboid.
The utility model also can be superimposed as a global facility with the original pressure switch of electric pressure cooking saucepan, can more save cost like this.
The beneficial effect of the utility model is, when abnormal conditions appearred in electric pressure cooking saucepan, when pot inner pressure reached the operating pressure of setting, original pressure switch can not be broken off heating power supply, and at this moment, pot inner pressure continues to rise; The continuation of pot inner pressure is risen drive screw (3) is continued to bottom offset with drive block (2); When pot inner pressure surpasses operating pressure to a certain setting value; Drive screw (3) meeting promotion elastic clip (11) down moves downward and flash switch (12) is broken off, and heating stops; Meanwhile, magnet (6) moves downward with elastic clip (11), and when flash switch (12) breaks off, is pulled together with magnetic screw (7).Therefore, the utility model is under improper situation, when original pressure switch can not opening pressure continues to rise; Also can break off heating power supply, and after breaking off, flash switch (12) is pulled together because of magnet (6) and magnetic screw (7) by the utility model; Can't automatically reset again; After must sending the guarantee of guarantee point, electric pressure cooking saucepan just can be reused, and has guaranteed safe in utilization; Simultaneously, when the utility model is repaired, only need magnet (6) and magnetic screw (7) manual work be pushed aside and can recover normal, very easy.

Fig. 2 is installed under the electric pressure cooking saucepan stay-warm case for the utility model, the partial structurtes sketch map of flash switch off-state during the electric pressure cooking saucepan non-normal working;
Fig. 3 is installed in the upward view under the electric pressure cooking saucepan stay-warm case for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Like Fig. 1, shown in Figure 3; The non-automatic pressure relief device that resets of a kind of electric pressure cooking saucepan; Comprise switch bracket 1, drive block 2, drive screw 3, locking nut 4, magnetic receiver 5, magnet 6, magnetic screw 7, micrometer adjusting screw 8, stay-warm case 9, go up rigid clip 10, following elastic clip 11 and flashing switch 12; Switch bracket 1 is installed on the outer wall of stay-warm case 9, and non-automatic reseat pressure releasing device assembly is fixedly mounted on the switch bracket 1, and is arranged side by side with the original pressure switch of electric pressure cooking saucepan 14.
The above-mentioned rigid clip 10 that goes up all is a sheet metal with following elastic clip 11; In the present embodiment, magnet 6 adopts cylinder, and is installed in down elastic clip 11 ends through magnetic receiver 5, and magnetic screw 7 is installed in rigid clip 10 ends and corresponding about in the of 6 with magnet.
Above-mentioned going up on the rigid clip 10 has circular hole 13, and is installed in down on the elastic clip 11 drive screw 3 on same center line, and the diameter of said circular hole 13 is greater than the diameter of drive screw 3.
Be convenient size of regulating the distance of drive screw 3 with the change setup pressure value, said drive screw 3 is locked by two locking nuts 4 on the two sides of following elastic clip 11.The position that changes locking nut 4 promptly can change the setting value of pressure.
When the utility model used, corresponding pot inner pressure was greater than original pressure switch 14 corresponding pot inner pressure when breaking off when it broke off.
During the electric pressure cooking saucepan operate as normal, original pressure switch 14 work, the utility model is failure to actuate.After the original pressure switch 14 of electric pressure cooking saucepan lost efficacy, non-automatic reseat pressure releasing device started.When electric pressure cooking saucepan pressure rose, the elastomer deformation displacement drove drive block 2 to bottom offset; 2 of drive blocks drive drive screw 3 to bottom offset, make down elastic clip 11 produce flexural deformation, along with pressure raises until pressure relief value gradually; At this moment, following elastic clip 11 flexural deformations are big more, make magnet 6 gradually near magnetic screw 7 until being pulled together each other; The 12 moments separation of flashing switch is cut off the electricity supply, and is as shown in Figure 2.
Electric pressure cooking saucepan is because of cutting off the electricity supply; Pot inner pressure descends gradually, and elastomer also returns to original state gradually, drives to drive 2 to top offset; But because the magnetic field intensity of magnet 6 has overcome the bending strength of time elastic clip 11 and can not automatically reset; Cause flashing switch 12 to keep separation, dissengaged positions, after this pot inner pressure is reduced to zero-pressure gradually, the safety when having guaranteed to use.
