Detailed implementation manners

[0029] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0031] 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.

[0032] As Figures 1 to 3 shown, the cooking appliance of this embodiment includes a solenoid valve assembly 10. The solenoid valve assembly 10 includes a solenoid valve 11 and an elastic sealing sleeve 12. Among them, the solenoid valve 11 includes a housing 111 and a driving member 112, and a part of the driving member 112 is located inside the housing 111. The elastic sealing sleeve 12 is sleeved on the part of the driving member 112 located outside the housing 111. An installation through hole 121 is provided on the elastic sealing sleeve 12, and the end of the driving member 112 passes through the installation through hole 121. The hole wall or the end face of the installation through hole 121 is adhesively fixedly connected to the driving member 112. The above-mentioned driving member 112 is also the push rod of the solenoid valve 11.

[0033] From Figure 7 it can be seen that the driving member 112 includes a pushing portion 1121 and a force-receiving portion 1122. Among them, the pushing portion 1121 is used to push the driven member multiple times, and the force-receiving portion 1122 is used to bear the constraint. The above-mentioned constraint refers to the constraint driving force applied by the external force-applying structure to the driving member 112. Specifically, the top head at the end of the push rod forms the above-mentioned pushing portion 1121, and the part of the push rod that cooperates with the electromagnetic coil in the housing 111 forms the force-receiving portion 1122.

[0034] Applying the technical solution of this embodiment, the hole wall or the end face of the installation through hole 121 is fixedly connected to the driving member 112. The above structure makes there be no gap between the installation through hole 121 and the driving member 112, so that steam cannot enter into the driving member 112 and the installation through hole 121, avoiding the situation that the solenoid valve 11 is prone to rust. Therefore, the technical solution of this embodiment solves the problem that air easily enters between the driving member and the sealing sleeve of the solenoid valve of the cooking appliance in the prior art and causes rust.

[0035] It should be noted that the above adhesion fixation includes, for example, in-mold injection or die-casting, ultrasonic welding, glue adhesion, etc.

[0036] It should be noted that the above driving member 112 is not limited to being used within the solenoid valve assembly 10. The driving member 112 can be used as a pushing structure in other driving structures. For example, the driving member 112 can be applied in a lever structure, or the driving member 112 can be applied in an electric push rod structure. Specifically, when the driving member 112 is the push rod in the solenoid valve 11, the driving member 112 performs a linear reciprocating motion. Of course, the driving member 112 can also be a rotational form of driving.

[0037] It should be noted that the elastic sealing sleeve 12 and the driving member 112 are connected in the following ways. One way is that the inner wall of the mounting through-hole 121 is fixedly connected to the outer side wall of the driving member 112. Another way is that the part of the inner wall or outer wall of the elastic sealing sleeve 12 corresponding to the end face of the mounting through-hole 121 is connected to the driving member 112. In the second way, the part of the elastic sealing sleeve 12 corresponding to the mounting through-hole 121 can be turned outwards or inwards, so that the inner wall or outer wall of the elastic sealing sleeve 12 is connected to the driving member 112. Of course, the connection method between the elastic sealing sleeve 12 and the driving member 112 is not limited to this. As long as gas cannot enter through the gap between the driving member 112 and the mounting through-hole 121, those skilled in the art can connect the two together by conventional technical means.

[0038] In the technical solution of this embodiment, the hole wall of the mounting through-hole 121 or the end face of the mounting through-hole 121 is connected to the driving member 112 through a vulcanization process. Preferably, the driving member 112 is made of metal, and the elastic sealing sleeve 12 is made of soft rubber or silica gel structure. The vulcanization process makes the contact surface between the mounting through-hole 121 and the driving member 112 form an integral structure. The vulcanization process is simple to operate and the connection is reliable at the same time.

[0039] The specific operation steps of the above vulcanization process are as follows:

[0040] 1. The driving member 112 is injection-molded by an injection molding machine. Among them, the plastic material used for the driving member 112 is PA66 + 30% GF, and the connection effect with the elastic sealing sleeve 12 is better after coating with an adhesive.

[0041] 2. Apply an adhesive to the mating surface of the driving member 112 and the elastic sealing sleeve 12, and let it dry.

[0042] 3. Place the dried driving member 112 into the mold, and inject liquid silicone into the mold under a certain pressure. After the molding cycle is completed, take out the product. After the plastic, adhesive, and silicone undergo a chemical reaction, the driving member 112 and the elastic sealing sleeve 12 are connected into an integral state.

[0043] Among them, the above-mentioned adhesive is a silicone adhesive, also known as a bridging agent. The silicone adhesive is a semi-fluid colloidal substance and is transparent. The silicone adhesive will undergo a cross-linking reaction under heating, irradiation or peroxide, a depolymerization reaction under the action of acid or alkali, and a combustion reaction in an open flame. The silicone adhesive is suitable for bonding materials such as silicone and hardware, silicone and plastic, silicone and silicone, and the silicone adhesive has the characteristics of good transparency, high strength, and good performance. Therefore, applying the silicone adhesive between the drive member 112 and the elastic sealing sleeve 12 can make the drive member 112 and the elastic sealing sleeve 12 better welded together.

[0044] Preferably, the hole wall of the installation through hole 121 or the end surface of the installation through hole 121 can also be connected to the driving member 112 by ultrasonic welding. The ultrasonic welding process melts the contact surface between the installation through hole 121 and the driving member 112 and connects them together with the driving member. The ultrasonic welding process makes the connection between the elastic sealing sleeve 12 and the driving member 112 reliable.

[0045] like Figure 3 and Figure 6 As shown, in the technical solution of this embodiment, a thickened portion 122 is provided at the mounting through hole 121. Specifically, the thickened portion 122 is provided on the side of the bottom wall of the elastic sealing sleeve 12 away from the opening thereof. The mounting through hole 121 is provided at the center of the thickened portion 122. The thickened portion can thicken the hole wall of the mounting through hole 121, thereby ensuring the connection strength between the mounting through hole 121 and the driving member 112. Preferably, the thickened portion 122 is a circular structure.

[0046] like Figure 3 and Figure 6 As shown, in the technical solution of this embodiment, the side wall of the elastic sealing sleeve 12 includes a pleated portion 123. Specifically, the pleated portion 123 includes one or more pleated structures. When the driving member 112 moves forward and backward, the elastic sealing sleeve 12 can be extended or contracted through the pleated portion.

[0047] like Figure 3 and Figure 7As shown, in the technical solution of this embodiment, a positioning groove 113 is provided on the side wall of the driving member 112 located outside the housing 111, and the hole wall of the mounting through hole 121 is clamped in the positioning groove 113. Specifically, the positioning groove 113 is an annular groove structure. The hole wall of the mounting through hole 121 is inserted into the positioning groove 113, thereby facilitating the positioning of the mounting through hole 121. Further, when the hole wall of the mounting through hole 121 is connected to the driving member 112, the hole wall of the mounting through hole 121 is connected to the annular outer peripheral surface of the positioning groove 113. When the inner side wall and the outer side wall of the elastic sealing sleeve 12 are connected to the driving member 112, the inner side wall and the outer side wall of the elastic sealing sleeve 12 are connected to the end surface of the positioning groove 113.

[0048] As Figure 1 and Figure 4 shown, in the technical solution of this embodiment, the cooking appliance includes a pot body 20 and a pot lid 30. Among them, the pot body 20 is used to hold the food to be cooked. The pot lid 30 is arranged on the pot body 20, and the pot lid 30 includes a lining 31 and a face cover 32 arranged on the lining 31. A pressure limiting valve 40 is arranged on the lining 31, the solenoid valve assembly 10 is arranged on the lining 31, and the driving member 112 cooperates with the pressure limiting valve 40. Specifically, from Figure 3 it can be seen that a push handle is arranged on the side wall of the pressure limiting valve 40, and when the driving member 112 of the solenoid valve 11 extends, it can push the pressure limiting valve 40 to rotate. A lifting inclined surface is arranged between the pressure limiting valve 40 and the mounting seat. During the rotation of the pressure limiting valve 40, the pressure limiting valve 40 rises under the action of the lifting inclined surface, thereby realizing exhaust. Of course, the above-mentioned pressure limiting valve assembly is not limited to being applied to the push-type solenoid valve 11, and the solenoid valve 11 can also be used as other driving source structures in the cooking appliance.

[0049] As Figures 3 to 5 shown, in the technical solution of this embodiment, a convex portion 311 is arranged on the lining 31, a receiving cavity 312 is arranged inside the convex portion 311, and the pressure limiting valve 40 is arranged in the receiving cavity 312. An avoidance hole 313 is arranged on the side wall of the convex portion 311. Among them, the solenoid valve assembly 10 is arranged outside the convex portion 311, and the part of the driving member 112 located outside the housing 111 and the part of the elastic sealing sleeve 12 extend into the receiving cavity 312 through the avoidance hole 313. From Figure 3As can be seen, the surface of the inner liner 31 bulges upward to form the above-mentioned convex portion 311. The convex portion 311 includes a top wall and a side wall, and the pressure limiting valve 40 is located within the convex portion 311. The end of the driving member 112 extends into the convex portion 311 after passing through the avoidance hole 313 and pushes against the pressure limiting valve 40. At the same time, a part of the elastic sealing sleeve 12 also extends into the convex portion 311 through the avoidance hole 313. Since a large amount of steam is generated when the pressure limiting valve 40 exhausts, by fixedly connecting the hole wall of the installation through hole 121 to the driving member 112, it is possible to prevent steam from flowing into the solenoid valve 11 through the gap between the installation through hole 121 and the driving member 112. Further, from Figure 3 As can be seen, the corrugated portion 123 is located within the convex portion 311.

[0050] As Figure 3 , Figure 5 and Figure 6 shown, in the technical solution of this embodiment, a positioning convex edge 124 is provided at the opening of the elastic sealing sleeve 12, and the positioning convex edge 124 is clamped between the outer side wall of the convex portion 311 and the housing 111. Specifically, the opening of the elastic sealing sleeve 12 is turned outward to form a flanging, that is, the above-mentioned positioning convex edge 124. The positioning convex edge 124 abuts against the outer side wall of the convex portion 311. At the same time, when the solenoid valve 11 is installed on the inner liner, the end face of the housing 111 facing the positioning convex edge 124 abuts against the positioning convex edge 124, that is, the positioning convex edge 124 is clamped between the outer side wall of the convex portion 311 and the housing 111. At the same time, the positioning convex edge 124 is clamped by the outer side wall of the convex portion 311 and the housing 111, thereby preventing steam from flowing into the gap between the avoidance hole 313 and the elastic sealing sleeve 12 and between the inner liner 31 and the face cover 32.

[0051] As Figure 3 and Figure 4 shown, in the technical solution of this embodiment, the cooking appliance further includes a pressing plate 50, the pressing plate 50 is covered on the housing 111, and a fastening member 60 is provided between the pressing plate 50 and the inner liner 31 to fix the housing 111 on the inner liner 31. Specifically, the fastening member 60 is a screw. Correspondingly, the pressing plate 50 is provided with an installation hole, and the inner liner 31 is provided with a screw post. After the pressing plate 50 is covered on the housing 111, the screw passes through the installation hole and the screw post to lock the pressing plate 50 on the inner liner 31.

[0052] As Figure 4 shown, in the technical solution of this embodiment, the pot lid 30 further includes an inner pot lid 33 detachably arranged below the inner liner 31, the pressure limiting valve 40 is arranged on the inner pot lid 33, and an installation opening 314 is provided at the position corresponding to the convex portion 311 on the lower surface of the inner liner 31, the installation opening 314 is communicated with the accommodation cavity 312, and when the inner pot lid 33 is installed on the inner liner 31, the pressure limiting valve 40 extends into the accommodation cavity 312 through the installation opening 314.

[0053] Preferably, the cooking appliance in this embodiment is an electric pressure cooker. Further, the above solenoid valve assembly can also be applied to other cooking appliances, such as rice cookers and the like.

[0054] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0055] In the description of the present application, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are generally based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus should not be construed as limiting the protection scope of the present application; the orientation words "inner, outer" refer to the inside and outside relative to the contour of each component itself.

[0056] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship of one device or feature shown in the drawings with respect to other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientation of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0057] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without additional declaration, the above terms have no special meaning, and therefore should not be construed as a limitation on the scope of protection of this application.
