[0002] With the development of society, people's lives are getting better and better. With the improvement of people's living standards, people pay more and more attention to healthy diet and the taste of food. Among them, food slow-cooked in a water bath at low temperature using a slow cooking device is very popular among people. By putting food into a bag, vacuuming it, and then putting it into a container filled with water and slow-cooking it in a water bath using a slow cooking device, the food can be made nutritious, tender and juicy, and the taste of the food can be effectively improved. The existing slow cooking device usually includes a shell, a top cover arranged on the top of the shell, a control panel arranged on the top of the top cover, and an electrical component arranged in the shell. The upper part of the shell is provided with an inclined surface structure extending obliquely toward the outer side of the top of the shell, which can increase the cross-sectional size of the top of the shell to install a larger control panel, thereby improving user convenience. However, due to the limitation of the demoulding direction, the force direction of the top cover when fixed is not perpendicular to the inclined surface, the fixation is prone to failure, and the user experience is not good. Utility Model Content

[0003] The present application provides a slow cooking device with a stable structure to solve the technical problems of existing cooking devices that the fixings are prone to failure and the user experience is poor.

[0004] To solve the above technical problems, the present invention provides a structurally stable slow cooking device, comprising a housing, a mounting surface on the top of the housing, the mounting surface being an inclined surface structure inclined from one side to the other; a mounting cavity within the housing for mounting electrical components; a top opening on the mounting surface communicating with the mounting cavity; a top cover enclosing the top opening; the top cover adapted to mate with the mounting surface; a plurality of mounting holes on the top cover, the central axes of the mounting holes being adapted to be perpendicular to the mounting surface; a plurality of fixing portions on the inner sidewall of the mounting cavity adjacent to the top opening, the fixing portions being provided with fixing holes corresponding to the mounting holes and having central axes coinciding with the central axes of the mounting holes; fasteners being positioned within the mounting holes and the fixing holes. By arranging the central axes of the fixing holes and the mounting holes to be perpendicular to the mounting surface, the cooking device can align the fixing direction of the top cover with the force direction of the fasteners, thereby improving the strength and stability of the connection between the fasteners and the top cover, thereby improving the structural stability and performance stability of the cooking device, and effectively enhancing the user experience.

[0005] In an optional embodiment, a reinforcing rib is provided on the outside of the fixing portion, and the reinforcing rib is adapted to connect the fixing portion to the inner wall of the mounting cavity. Providing the reinforcing rib on the outside of the fixing portion effectively enhances the connection strength between the fixing portion and the inner wall of the mounting cavity, thereby ensuring the stability of the connection between the top cover and the housing.

[0006] In an optional embodiment, the fixing portion includes a mounting slot extending inward from the outside and a fixing nut disposed in the mounting slot. The fixing nut has a central portion defining the fixing hole with an internal thread. One end of the fastener is positioned within the mounting hole, while the other end has an external thread and is threadedly engaged with the fixing nut. Threading the fastener to the fixing portion not only ensures the connection strength between the fastener and the fixing portion, but also enhances the stability of the connection between the top cover and the housing.

[0007] In an optional embodiment, the longitudinal cross-section of the mounting slot is adapted to be a trapezoidal shape that is narrow at the top and wide at the bottom, and the cross-sectional dimensions of the upper portion of the mounting slot are smaller than the outer dimensions of the fixing nut. By configuring the longitudinal cross-section of the mounting slot to be a trapezoidal shape that is narrow at the top and wide at the bottom, and configuring the cross-sectional dimensions of the upper portion of the mounting slot to be smaller than the outer dimensions of the fixing nut, not only can the structural strength of the upper portion of the mounting slot be increased and the possibility of fixation failure due to stress damage to the upper portion of the mounting slot be reduced, but the fixing nut can also be limited in position, reducing connection failure or loosening due to loosening of the fixing nut, effectively improving the connection strength and stability between the top cover and the outer shell, and ensuring the structural stability and performance stability of the cooking device.

[0008] In an optional embodiment, the inner side wall of the mounting groove includes a left side wall and a right side wall that are relatively arranged, and the left side wall and the right side wall are adapted to be vertical planes extending laterally. The outer side of the fixing nut is provided with a plurality of limiting surfaces that match the left side wall and the right side wall, and the fixing nut is adapted to abut against the inner side wall of the mounting groove through the limiting surfaces. The left side wall and the right side wall of the mounting groove are adapted to limit and / or guide the fixing nut. By limiting and / or guiding the fixing nut through the left side wall and the right side wall of the mounting groove, not only can the difficulty of installing the fixing nut be effectively reduced, and the production cost and the user's cost be reduced, but also the situation in which the fixing nut becomes loose and causes the fixing to fail or the connection to become loose can be avoided, and the connection stability between the top cover and the outer shell can be effectively ensured.

[0009] In an optional embodiment, the fixing portion is adapted to be integrally formed with the inner wall of the mounting cavity. By configuring the fixing portion to be integrally formed with the inner wall of the mounting cavity, not only can the production process and the structure of the cooking device be simplified, reducing production costs and user costs, but the connection strength between the fixing portion and the inner wall of the mounting cavity can also be ensured, thereby improving the stability of the connection between the top cover and the housing via the fixing portion.

[0010] In an optional embodiment, the mounting surface is provided with a stepped portion located around the periphery of the top opening, and the bottom of the top cover is provided with an extension portion extending downward and matching the shape of the stepped portion, with the top cover being adapted to be sleeved onto the outer side of the stepped portion via the extension portion. The stepped portion is adapted to limit and / or position the top cover during installation. By limiting and / or positioning the top cover via the stepped portion, the difficulty of installing the top cover can be effectively reduced, thereby lowering both production costs and user costs.

[0011] In an optional embodiment, an annular seal made of elastic material is positioned on the inner side of the extension, corresponding to the stepped portion. The stepped portion is adapted to sealably engage the top cover via the seal. Providing the seal on the inner side of the extension ensures a sealed connection between the top cover and the outer shell, preventing external liquid from entering the mounting cavity through the connection gap and potentially damaging electrical components therein, thereby effectively improving the safety and performance stability of the cooking device.

[0012] In an optional embodiment, a limiting slot is provided on one side of the seal corresponding to the top cover, and a limiting portion is provided on the bottom of the top cover corresponding to the limiting slot, the limiting portion being adapted to engage with the limiting slot. The limiting portion is adapted to limit and / or position the seal. Limiting and / or positioning the seal by the limiting portion not only effectively reduces the difficulty of installing the seal, but also prevents sealing failure due to sliding of the seal, thereby effectively improving the sealing stability of the seal.

[0013] In an optional embodiment, a recess is provided in the middle of the top cover, the mounting hole is provided in the recess, and a control panel is positioned within the recess for communication with the electrical components within the mounting cavity. The control panel covers the mounting hole and seals against the inner wall of the recess. By providing the mounting hole within the recess and covering it with the control panel, the mounting hole can be concealed, thereby enhancing the overall aesthetics of the cooking device. Furthermore, by providing a seal between the control panel and the inner wall of the recess, external liquids can be prevented from entering the mounting cavity through the recess and the mounting hole, potentially damaging the electrical components within the cavity, thereby effectively improving the safety and performance stability of the cooking device.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] By setting the mounting holes and the central axis of the fixing holes on the top cover and the fixing part to be perpendicular to the mounting surface, the present application can make the fixing direction of the top cover consistent with the force direction of the fastener, thereby improving the connection strength and connection stability between the fastener and the top cover, thereby improving the structural stability and performance stability of the cooking device, and effectively improving the user experience.

[0020] The following description is intended to disclose the present invention and enable those skilled in the art to implement the present invention. The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0021] 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.

[0022] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the 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 drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary and not as limitations. 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.

[0023] 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 accompanying 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.

[0024] And for ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and 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.

[0025] Furthermore, it should be noted that the term "a" should be understood as "at least one" or "one or more." That is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be one or more. The term "a" should not be construed as limiting the quantity. The use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this utility model.

This improves the connection strength and stability between the fasteners 15 and the top cover 20, thereby improving the structural stability and performance stability of the cooking device, and effectively enhancing the user experience.

[0028] like Figure 3 and Figure 4 As shown, in an optional embodiment, a reinforcing rib 142 is provided on the outside of the fixing portion 14.
