Below with reference to Fig. 1-Fig. 3 descriptions according to the pressure relief device 30 for cooking apparatus of the utility model embodiment.

As shown in Figure 1-Figure 3, cooking cavity 11 and pressure release are had according to the cooking apparatus 100 of the utility model one embodiment Hole 21, relief hole 21 are connected with cooking cavity 11, and pressure relief device 30 includes：Pressure release component 31 and drive component 32.

Pressure release component 31 is used to open and blocks relief hole 21, and pressure release component 31 is movably disposed at relief hole 21, There is pressure release component 31 first magnet 311, drive component 32 to have moveable second magnet 321, the second magnet 321 and first Magnet 311 is same polarity magnetic material piece,

Pressure relief device 30 is configured to following state：When drive component 32 drive the second magnet 321 towards with the first magnet When the position movement of 311 faces, pressure release component 31 is moved towards relief hole 21, so as to block relief hole 21；Work as driving group When part 31 drives the second magnet 321 to be moved towards the position that is staggered with the first magnet 321, pressure release component 31 far from relief hole 21, So as to open relief hole 21.

Face position described herein refers to that the second magnet 321 is located at the first magnet 311 and is distributed just with relief hole 21 Histogram refers to that the second magnet 321 is located at non-first magnet 311 to the position of (horizontal or vertical), staggered positions described herein Except the position in the honest direction being distributed with relief hole 21.

For example, in the example shown in fig. 1, the first magnet 311 and the distribution of about 21 relief hole, when the second magnet 321 It is face position, the second magnet 321 and the first magnet 311 are mutually exclusive at this time, and driving is let out when the first 311 surface of magnet Pressure component 31 is moved along towards the direction of relief hole 21, to block relief hole 21.When the second magnet 321 deviates the first magnet It is staggered positions, repulsive force reduces at this time, lets out when 311 surface (such as being located at the upper left side of the first magnet 311 in Fig. 2) It presses component 31 under the action of elastic force or other active forces, is moved along the direction far from relief hole 21, to open relief hole 21.

According to the pressure relief device 30 for cooking apparatus of the utility model embodiment, by using with the second magnet 321 drive component 32, the principle repelled each other using the same polarity of same polarity magnetic material piece, driving carry the first magnet 311 Pressure release component 311, to make pressure release component 31 block or open relief hole 21, and the second magnet 321 can with the first magnet Face and the direction movement being staggered, advantageously reduce the lid height of cooking apparatus, to reduce cost, reduce lid volume, It compared to traditional pressure relief device, eliminates and covers trepanning upper, maintain good leakproofness, while eliminating herein close Sealing, the problems such as avoiding aging, poor sealing caused by sealing element long-time use, to further improve pressure release dress Set 30 leakproofness.

One embodiment according to the present utility model, the second magnet 321 are moved to the position with 311 face of the first magnet When, the homopolarity face of the first magnet 311 and the second magnet 321 can be obtained by homopolar-repulsion principle, the first magnet 311 and the second magnetic Iron 321 repels each other, and under the action of mutual expelling force, the first magnet 311 is directed away from the direction movement of the second magnet 321, thus pressure release Component 31 blocks relief hole 21.

As shown in figure 3, one embodiment according to the present utility model, drive component 32 includes lateral push rod 325, is laterally pushed away Bar 325 can laterally move, i.e., transverse direction push rod 325 can move left and right, and the second magnet 321 is connected to lateral push rod 325 One end (right end as shown in Figure 3), to when lateral push rod 325 moves left and right, drive the second magnet 321 to move left and right, make It is closer or far from the position opposite with the first magnet 311.

In some instances, drive component 32 further includes electromagnet 322 and drive rod 323, and drive rod 323 is in electromagnet The lower movement of 322 drivings, drive rod 323 and the lateral one end (left end as shown in Figure 3) of push rod 325 far from the second magnet 321 are even It connects, to drive lateral push rod 325 to move left and right.

323 outer cover of drive rod is equipped with spring 324, the both ends of spring 324 respectively with the free end of drive rod 323 and electromagnetism Iron 322 only supports connection, and spring 324 can play the movement of drive rod 323 cushioning effect, and when the movement of drive rod 323 drives After spring 324 compresses, spring 324 can replace the suction of electromagnet 322, make spring return of the drive rod 323 by spring 324 To initial position.

As shown in figure 3, in some instances, the free end of drive rod 323 is equipped with clamping portion 3231, lateral push rod 325 with The clamping of clamping portion 3231 is connected.Specifically, the right end of drive rod 323 forms the free end of drive rod 323.Lateral push rod 325 is set The right end in drive rod 323 is set, the left end of lateral push rod 321 forms grab, and grab is connected with the clamping of clamping portion 3231, thus will Lateral push rod 321 is fixedly connected with drive rod 323, and the two is made to realize synchronizing moving.

One embodiment according to the present utility model, pressure release component 31 include：Valve body 312, spool 313 and sealing 314.

Valve body 312 has the channel 3123 extended longitudinally, and channel 3123 is connected to relief hole 21, and spool 313 is arranged In valve body 312, spool 313 is axially extending along valve body 312, and the first magnet 311 is connected to one end of spool 313 (such as Fig. 3 institutes The upper end shown), sealing 314 is connected to the other end (lower end as shown in Figure 3) of spool 313, and the first magnet 311 can drive Spool 313 moves up and down, and to drive sealing 314 to move, sealing 314 is made to open and block relief hole 21.

As shown in figure 3, in some instances, the middle part of spool 313 has support portion 3131, and support portion 3131 is along spool 313 project radially outward, is additionally provided with elastic component 315 in valve body 312, the both ends of elastic component 315 are only butted on support portion respectively 3131 and valve body 312 inner wall (such as bottom wall).

Specifically, under the action of mutual expelling force between the second magnet 321 and the first magnet 311, spool 313 overcomes elasticity The effect of part 315 moves downward, and the sealing 314 of 313 lower end of spool blocks relief hole 21, to reach sealing state.When Second magnet 321 gradually weakens far from the first magnet 311, mutual expelling force between the two, under the elastic force effect of elastic component 315, It pushes support portion 3131 to be moved upwards with spool 313, relief hole 21 is opened.

In some specific examples, valve body 312 includes：Valve seat 3121 and valve deck 3122, valve deck 3122 are located at valve seat On 3121.When installation, sealing 314 is first mounted on to the lower end of spool 313, one end of elastic component 315 is only against support portion On 3131, then by spool 313 on valve seat 3121, so that the other end of elastic component 315 is only against on valve seat 3121, finally will Valve deck 3122 is located on valve seat 3121.It, can be in order to spool 313, sealing i.e. by the way that separable 312 structure of valve body is arranged 314 and elastic component 315 installation.

Optionally, sealing ring 316 is additionally provided between valve deck 3122 and valve seat 3121, valve deck 3122 is with valve seat 3121 by close Seal 316 is tightly connected, and to ensure the leakproofness between valve seat 3121 and valve deck 3122, improves the sealing of pressure relief device 30 Property.

Certainly, valve seat 3121 and valve deck 3122 can also be integral piece, and integrally formed structure can be further increased and be let out The leakproofness of pressure device 30.
