Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, and in particular to a valve body structure, a cover body assembly and a cooking utensil. Background Art

[0002] Valves are widely used to control the flow and shutoff of liquids, gases, powders, and other media. Typically, a valve comprises a valve body, which is provided with an inlet and multiple outlets. A valve plate is provided within the valve body, which can adjust the flow between the inlet and the outlets.

[0003] In the related art, the driving member can push the valve plate to control the flow and cutoff of the valve. When the driving member is extended or retracted, it needs to occupy a large space, which in turn causes the overall structure of the valve to occupy a large space. Utility Model Content

[0004] The main purpose of the utility model is to provide a valve body structure, a cover assembly and a cooking utensil to solve the problem that the valve in the related art occupies a large space.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a valve body structure is provided, which is arranged on a mounting base, and the valve body structure includes: a valve seat, the valve seat having a valve cavity, an inlet connected to the valve cavity, and multiple outlets connected to the valve cavity; a sealing structure, including a connecting piece and multiple sealing pieces connected to the connecting piece, and the multiple sealing pieces are arranged in a one-to-one correspondence with the multiple outlets, wherein the sealing structure has a sealing state and an avoidance state, when the sealing structure is in the sealing state, each seal blocks the corresponding outlet, and when the sealing structure is in the avoidance state, each seal avoids the corresponding outlet; a magnetic drive structure, the magnetic drive structure can drive the sealing structure to move so that the sealing structure switches between the sealing state and the avoidance state.

[0006] Applying the technical solution of the present invention, the valve body structure includes a valve seat, a sealing structure and a magnetic drive structure. The valve seat has a valve cavity, an inlet and multiple outlets. The sealing structure includes a connector and multiple seals connected to the connector. The multiple seals are arranged in a one-to-one correspondence with the multiple outlets. The magnetic drive structure can drive the sealing structure to switch the sealing structure between a sealing state and an avoidance state. Through the above-mentioned arrangement, the magnetic drive structure is driven by a magnetic field without extending or retracting, that is, the magnetic drive structure occupies less space, thereby making the overall size of the valve body structure smaller. At the same time, the driving stability of the magnetic drive structure is also better. Therefore, the technical solution of the present application can effectively solve the problem of the large space occupied by the overall structure of the valve in the related art.

[0007] Furthermore, the magnetic drive structure includes a first electromagnetic component and a first magnetic component, the first electromagnetic component and the first magnetic component magnetically cooperate with each other, one of the first electromagnetic component and the first magnetic component is disposed on the connector, and the other of the first electromagnetic component and the first magnetic component is disposed on the mounting base or the valve seat. The first electromagnetic component and the first magnetic component have a simple structure and are easy to dispose. The first electromagnetic component can be magnetic or non-magnetic by turning the power on and off. When the first electromagnetic component is de-energized, the first electromagnetic component and the first magnetic component do not cooperate. When the first electromagnetic component is energized, the first electromagnetic component and the first magnetic component attract or repel each other, thereby driving the sealing structure to move.

[0008] Furthermore, the first magnetic member is a permanent magnet, and the first electromagnetic member is a variable-pole electromagnet. Permanent magnets are relatively inexpensive, thereby reducing the overall cost of the valve body structure. The variable-pole electromagnet can attract or repel the permanent magnet, thereby driving the sealing structure to switch between a sealing state and a retracting state.

[0009] Furthermore, there is a gap between the first electromagnetic component and the first magnetic component. The above arrangement can prevent the first electromagnetic component and the first magnetic component from being closely attached to each other.

[0010] Furthermore, the magnetic drive structure also includes a second electromagnetic component and a second magnetic component, the second electromagnetic component and the second magnetic component are magnetically coupled, one of the second electromagnetic component and the second magnetic component is arranged on the connecting component, the other of the second electromagnetic component and the second magnetic component is arranged on the mounting base or the valve seat, the first electromagnetic component and the first magnetic component are both arranged at the first end of the connecting component, and the second electromagnetic component and the second magnetic component are both arranged at the second end of the connecting component. The second electromagnetic component and the second magnetic component are located at the second end of the sealing structure, the first electromagnetic component and the first magnetic component are located at the first end of the sealing structure, the first electromagnetic component and the first magnetic component can cooperate with each other to put the sealing structure in a sealed state, the second electromagnetic component and the second magnetic component can cooperate with each other to put the sealing structure in an avoidance state, or the first electromagnetic component and the first magnetic component can cooperate with each other to put the sealing structure in an avoidance state, the second electromagnetic component and the second magnetic component can cooperate with each other to put the sealing structure in a sealed state.

[0011] Furthermore, the first magnetic member and the second magnetic member are both arranged on the connecting member. The above arrangement can make the overall structure simpler, and the wires of the first electromagnetic member and the second electromagnetic member do not need to move with the sealing structure.

[0012] Furthermore, the first electromagnetic member and the second electromagnetic member have the same magnetic pole. The above arrangement can ensure that the driving sealing structure can be switched between the sealing state and the avoidance state.

[0013] Furthermore, the plurality of seals include a first sealing ring and a second sealing ring, both of which are disposed on the connector, the outlet includes a first outlet and a second outlet, the first sealing ring is disposed correspondingly to the first outlet, and the second sealing ring is disposed correspondingly to the second outlet, the first sealing ring is located inside the valve cavity, and the second sealing ring is located outside the valve cavity, or both the first sealing ring and the second sealing ring are located outside the valve cavity, or both the first sealing ring and the second sealing ring are located inside the valve cavity. The first sealing ring can block or avoid the first outlet, and the second sealing ring can block or avoid the second outlet, which can make the overall structure relatively simple and can effectively ensure the sealing effect.

[0014] According to a second aspect of the present invention, a cover assembly is provided, comprising a valve structure, wherein the valve structure is the valve structure described above.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0025] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to actual proportional relationships. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0026] In the prior art, valves are driven by solenoid valves. Extension or retraction of the solenoid valves drives the valve plate to move, thereby adjusting the flow and shutoff of the valve. However, since the solenoid valves require a certain amount of space to extend, the overall structure of the valves requires a large space.

[0027] In order to solve the above problems, Figures 1 to 3 As shown, in this embodiment, the valve body structure is disposed on a mounting base and includes: a valve seat 10, a sealing structure 20, and a magnetic drive structure 30. The valve seat 10 has a valve cavity 11, an inlet 12 communicating with the valve cavity 11, and a plurality of outlets 13 communicating with the valve cavity 11. The sealing structure 20 includes a connector 21 and a plurality of sealing members 22 connected to the connector 21. The plurality of sealing members 22 are arranged in a one-to-one correspondence with the plurality of outlets 13. The sealing structure 20 has a sealing state and a retracting state. When the sealing structure 20 is in the sealing state, each sealing member 22 blocks the corresponding outlet 13. When the sealing structure 20 is in the retracting state, each sealing member 22 retracts the corresponding outlet 13. The magnetic drive structure 30 is capable of driving the sealing structure 20 to move so as to switch the sealing structure 20 between the sealing state and the retracting state.

[0028] Applying the technical solution of this embodiment, the valve body structure includes a valve seat 10, a sealing structure 20 and a magnetic drive structure 30. The valve seat 10 has a valve cavity 11, an inlet 12 and multiple outlets 13. The sealing structure 20 includes a connector 21 and multiple seals 22 connected to the connector 21. The multiple seals 22 are arranged in a one-to-one correspondence with the multiple outlets 13. The magnetic drive structure 30 can drive the sealing structure 20 to switch the sealing structure 20 between a sealing state and an avoidance state. Through the above-mentioned arrangement, the magnetic drive structure 30 is driven by a magnetic field without extending or retracting, that is, the magnetic drive structure 30 occupies a smaller space, thereby making the overall size of the valve body structure smaller. At the same time, the driving stability of the magnetic drive structure 30 is also better. Therefore, the technical solution of this embodiment can effectively solve the problem of the large space occupied by the overall structure of the valve in the related art.

[0029] like Figure 1 and Figure 2 As shown, in this embodiment, the magnetic drive structure 30 includes a first electromagnetic component 31 and a first magnetic component 32. The first electromagnetic component 31 and the first magnetic component 32 are magnetically coupled. The first magnetic component 32 is disposed on the connector 21, and the first electromagnetic component 31 is disposed on the mounting base or the valve seat 10. The structures of the first electromagnetic component 31 and the first magnetic component 32 are simple and easy to set up. The first electromagnetic component 31 can be magnetically or non-magnetically coupled by turning the power on and off. When the first electromagnetic component 31 is de-energized, the first electromagnetic component 31 and the first magnetic component 32 do not engage. When the first electromagnetic component 31 is energized, the first electromagnetic component 31 and the first magnetic component 32 attract or repel each other, thereby driving the sealing structure 20 to move.

[0030] In an embodiment not shown in the figures, the first magnetic component 32 is disposed on the mounting base or the valve seat 10 , and the first electromagnetic component 31 is disposed on the connecting component 21 .

[0031] like Figure 1 and Figure 2 As shown, in this embodiment, the first magnetic member 32 is a permanent magnet, and the first electromagnetic member 31 is a variable-pole electromagnet. Permanent magnets are relatively inexpensive, which in turn reduces the overall cost of the valve body structure. The variable-pole electromagnet can attract or repel the permanent magnet, thereby driving the sealing structure 20 to switch between a sealing state and a retracting state.

[0032] Specifically, when the magnetic pole of the first electromagnetic element 31 is at level N, it attracts the first magnetic element 32, thereby maintaining the sealing structure 20 in a sealed state. When the magnetic pole of the first electromagnetic element 31 is at level S, it repels the first magnetic element 32, thereby driving the sealing structure 20 from the sealed state to the avoidance state. When the first electromagnetic element 31 is de-energized, it does not drive the sealing structure 20 to move.

[0033] like Figure 1 and Figure 2 As shown, in this embodiment, there is a gap between the first electromagnetic member 31 and the first magnetic member 32. The above arrangement can prevent the first electromagnetic member 31 and the first magnetic member 32 from being tightly attached to each other.

[0034] like Figure 4 As shown, in this embodiment, the magnetic drive structure 30 also includes a second electromagnetic component 33 and a second magnetic component 34, and the second electromagnetic component 33 and the second magnetic component 34 are magnetically coupled. The second magnetic component 34 is arranged on the connecting component 21, and the second electromagnetic component 33 is arranged on the mounting base or the valve seat 10. The first electromagnetic component 31 and the first magnetic component 32 are both arranged at the first end of the connecting component 21, and the second electromagnetic component 33 and the second magnetic component 34 are both arranged at the second end of the connecting component 21. The second electromagnetic component 33 and the second magnetic component 34 are located at the second end of the sealing structure 20, and the first electromagnetic component 31 and the first magnetic component 32 are located at the first end of the sealing structure 20. The first electromagnetic component 31 and the first magnetic component 32 can cooperate with each other to put the sealing structure 20 in a sealed state, and the second electromagnetic component 33 and the second magnetic component 34 can cooperate with each other to put the sealing structure 20 in an avoidance state, or the first electromagnetic component 31 and the first magnetic component 32 can cooperate with each other to put the sealing structure 20 in an avoidance state, and the second electromagnetic component 33 and the second magnetic component 34 can cooperate with each other to put the sealing structure 20 in a sealed state.

[0035] like Figure 4 As shown, in this embodiment, the first magnetic member 32 and the second magnetic member 34 are both provided on the connecting member 21. The above arrangement can make the overall structure relatively simple, and the wires of the first electromagnetic member 31 and the second electromagnetic member 33 do not need to move with the sealing structure 20.

[0036] like Figure 4As shown, in this embodiment, the magnetic poles of the first electromagnetic member 31 and the second electromagnetic member 33 are the same. The above arrangement can ensure that the driving sealing structure 20 can be switched between the sealing state and the avoidance state.

[0037] It should be noted that when the first electromagnetic component 31 and the second electromagnetic component 33 are provided, the first magnetic component 32 and the second electromagnetic component 33 may be permanent magnets or metals that can be magnetically attracted.

[0038] The plurality of sealing members 22 include a first sealing ring 221 and a second sealing ring 222, both of which are disposed on the connector 21. The outlet 13 includes a first outlet 131 and a second outlet 132. The first sealing ring 221 is disposed correspondingly to the first outlet 131, and the second sealing ring 222 is disposed correspondingly to the second outlet 132. The first sealing ring 221 is located inside the valve cavity 11, and the second sealing ring 222 is located outside the valve cavity 11. The first sealing ring 221 can block or avoid the first outlet 131, and the second sealing ring 222 can block or avoid the second outlet 132. This simplifies the overall structure and effectively ensures a sealing effect.

[0039] Specifically, the fluid in the valve chamber 11 simultaneously exerts force on the first sealing ring 221 and the second sealing ring 222. Thus, when the sealing member 22 blocks the outlet 13, the fluid can squeeze the first sealing ring 221 and the second sealing ring 222, thereby causing the second sealing ring 222 to have a tendency to move away from the first sealing ring 221, thereby achieving a better sealing effect. Since the first sealing ring 221 and the second sealing ring 222 are both arranged on the connecting member 21 and the first sealing ring 221 and the second sealing ring 222 can move synchronously, when the sealing member 22 moves from blocking the outlet 13 to opening the outlet 13, the fluid can flow out from the gap between the second sealing ring 222 and the corresponding second outlet 132. At the same time, there is also a gap between the first sealing ring 221 and the corresponding first outlet 131, through which the fluid can flow out. At this time, when the connecting member 21 continues to move, the sealing member 22 encounters less resistance, that is, the movement of the sealing structure 20 is relatively easy.

[0040] In an embodiment not shown in the figures, the first sealing ring 221 and the second sealing ring 222 are both located outside the valve cavity 11, or the first sealing ring 221 and the second sealing ring 222 are both located inside the valve cavity 11. The above arrangement can also achieve blocking and avoiding the first outlet and the second outlet.

[0041] According to a second aspect of the present application, a cover assembly is provided. The cover assembly of this embodiment includes a valve structure, which is the valve structure described above. The valve structure described above is driven by a magnetic drive structure, thereby reducing the space occupied by the valve structure. In other words, the valve structure occupies less space on the cover assembly, thereby effectively saving space on the cover assembly.

[0042] According to a third aspect of the present application, a cooking utensil is provided. The cooking utensil of this embodiment includes a cover assembly, which is the above-mentioned cover assembly. The above-mentioned cover assembly has a relatively reasonable spatial arrangement, and the valve body structure does not need to occupy a large space. Therefore, the cooking utensil including the above-mentioned cover assembly also has the above-mentioned advantages.

[0043] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0044] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0045] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
