Cooking apparatus internal pressure is put, while when not needing pressure release, weight is located at steam outlet by self gravity lid.Therefore, weight
Hammer must have constant weight, just be avoided that cooking apparatus when not needing pressure release, steam will not leak, and also therefore, drive
When weight, electromagnetic coil needs to lead to biggish electric current, and electromagnetic coil generally has biggish volume, is just able to achieve counterweight hammer
Effectively driving, realization are precisely controlled weight, this has resulted in the increase of cooking apparatus energy consumption, and electromagnetic coil assembly is fabricated to
This increase.In addition, skew easily occurs for weight during electromagnetic coil driving weight is mobile, cause electromagnetic coil with
Magnetic attraction between weight varies widely, to influence to be precisely controlled weight.
Utility model content
The utility model aims to solve the problem that one of the technical problems existing in the prior art.
For this purpose, the first aspect of the utility model proposes a kind of pressure adjusting structure.
The second aspect of the utility model proposes a kind of cover assembly.
The third aspect of the utility model proposes a kind of cooking apparatus.
In view of this, the utility model first aspect proposes a kind of pressure adjusting structure, it to be used for cooking apparatus, pressure adjusting structure packet

In order to be more clearly understood that the above objects, features, and advantages of the utility model, with reference to the accompanying drawing and have
The utility model is further described in detail in body embodiment.It should be noted that in the absence of conflict, this Shen
The feature in embodiment and embodiment please can be combined with each other.
Many details are explained in the following description in order to fully understand the utility model, still, this is practical
Novel to be implemented using other than the one described here other modes, therefore, the protection scope of the utility model is simultaneously
It is not limited by the specific embodiments disclosed below.
The pressure adjusting structure according to the utility model some embodiments, cover assembly 10 are described referring to Fig. 1 to Fig. 7
And cooking apparatus.
As shown in Figures 1 to 6, the utility model first aspect embodiment proposes a kind of pressure adjusting structure, is used for cooking pot
Tool, pressure adjusting structure includes: switch block 12, and at mobilizable steam (vapor) outlet 106 that cooking apparatus is arranged in, switch block 12 is wrapped
Permanent magnet 122 and clump weight 124 are included, permanent magnet 122 is circumferentially distributed around the center line for being moved along it direction of clump weight 124,
The side of permanent magnet 122 is arranged in clump weight 124；Electromagnetic coil assembly 14 is powered and generates magnetic force between permanent magnet 122, with
Driving switch component 12 is close to or far from steam (vapor) outlet 106.
The utility model passes through permanent magnet 122 and electromagnetic coil assembly by the way that permanent magnet 122 is arranged in switch block 12
Magnetic force interaction between 14, enables switch block 12 is easier to be driven by electromagnetic coil assembly 14, so that electromagnetic coil
Component 14 need not lead to very big electric current, and generating lesser magnetic force can effectively move driving switch component 12, reduce electromagnetic wire

124 center line for being moved along it direction is circumferentially distributed, enables the preferably driving switch component 12 of electromagnetic coil assembly 14
To predeterminated position, so that the movement of switch block 12 is more steady, permanent magnet 122 is avoided to be located at the whole a corner of switch block 12,
And after causing electromagnetic coil assembly 14 to be powered, because of its stronger magneticaction between permanent magnet 122, and driving switch component 12
Skew offset occurs, and then leads to not the gap size between effective control switch component 12 and steam (vapor) outlet 106, Wu Fajing
Quasi- control cooking apparatus inside pressure in addition switch block 12 can because occur skew due to other structures around interfere and
It can not continue to move to, thoroughly lose voltage regulation result.Therefore, direction is moved along it around clump weight by limiting permanent magnet 122
Center line it is circumferentially distributed so that switch block 12 is whole towards being more uniformly stressed everywhere in electromagnetic coil assembly 14, favorably
In the steady movement for guaranteeing switch block 12.
In addition, switch block 12 further includes clump weight 124, so can by replace the clump weight 124 of different weight come
The whole weight of regulating switch component 12 meets it to the preset pressure at steam (vapor) outlet 106, when avoiding not needing pressure release,
Cooking apparatus internal pressure is excessive, and steam opens switch block 12 and releases from steam (vapor) outlet 106, influences to cook effect, together
When, by replacing or adding the clump weight 124 of different weight come the weight of regulating switch component 12, but also 12 energy of switch block
Enough it is suitable for the pressure inside a variety of cooking apparatus to adjust, improves the versatility of switch block 12 and pressure adjusting structure.Specifically,
The side of permanent magnet 122 is arranged in clump weight 124, convenient to limit to permanent magnet 122, and is convenient for permanent magnet 122 and counterweight
The installation of block 124.
In one embodiment of the utility model, it is preferable that as shown in figure 5, clump weight 124 it is any perpendicular to its
