[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some, but not all, of the embodiments of this application.

[0048] Regarding the technical problems existing in the related art, refer to Figure 1 as shown in Figure 1It is a schematic diagram of the overall structure of the cover assembly provided by the embodiments of the present application. The first aspect of the embodiments of the present application provides a cover assembly 2, including: a first cover 10 and a second cover 20.

[0049] Specifically, in the embodiments of the present application, the first cover 10 and the second cover 20 may be Figure 1 the circular structures shown in the figure. Among them, the first cover 10 may be an outer cover, and the second cover 20 may be an inner cover. In specific implementation, the materials or materials of the first cover 10 and the second cover 20 may be the same, for example, both are made of food-grade plastic.

[0050] Among them, a rotating column 11 is provided on one of the first cover 10 and the second cover 20, and a first shaft hole 21 is provided on the other of the first cover 10 and the second cover 20. The rotating column 11 can be inserted into the first shaft hole 21 and rotate relative to the first shaft hole 21.

[0051] Optionally, the rotating column 11 may be provided on the first cover 10, and the first shaft hole 21 may be provided on the second cover 20.

[0052] Among them, the rotating column 11 may be integrally formed with the first cover 10. In some possible examples, the rotating column 11 may also be obtained by secondary injection molding. It can be understood that the first shaft hole 21 and the second cover 20 may also be integrally formed. Of course, the first shaft hole 21 may also be obtained by secondary processing, such as by using tools such as a lathe and a milling cutter to dig holes for forming.

[0053] It can be understood that in the embodiments of the present application, the rotating column 11 can be inserted into the first shaft hole 21 and rotate along the axial direction of the rotating column 11. In this way, the first cover 10 and the second cover 20 can rotate relative to each other in the circumferential direction. Thus, when the cover assembly 2 is covered on the cup body or the body of the cooking machine, the first cover 10 can press the second cover 20 against the inner wall of the cup body or the body, and the first cover 10 and the second cover 20 rotate relative to each other, without having to overcome the friction between the sealing ring on the second cover 20 and the cup body or the body. Therefore, it can facilitate the user to cover the cover assembly 2 on the cup body or the body, and can improve the user experience.

[0054] It can be understood that after use, it is necessary to open the cover assembly 2. At this time, the user can conveniently twist the first cover 10. In order to enable the first cover 10 to drive the second cover 20 to open together, referring to Figure 1 as shown, in the embodiments of the present application, a metal clamping member (not labeled in the figure) is provided on the circumferential wall of the rotating column 11. When the rotating column 11 is inserted into the first shaft hole 21, the metal clamping member can be clamped with the hole edge of the first shaft hole 21 to prevent the rotating column 11 from moving out of the first shaft hole 21.

[0055] Specifically, in the embodiment of the present application, the metal clamping piece can be fixedly connected to the peripheral wall of the rotating column 11. For example, when the rotating column 11 is injection molded, part of the metal clamping piece is pre-embedded in the peripheral wall of the rotating column 11, so that the metal clamping piece is embedded in the peripheral wall of the rotating column 11. In some optional methods, the metal clamping piece can also be fixedly connected to the peripheral wall of the rotating column 11 by connecting parts such as rivets, screws, bolts or screws.

[0056] In this way, a slot will be formed between the end face of the metal clip facing away from the rotating column 11 and the first cover body 10. After the rotating column 11 is inserted into the first axial hole 21, the edge of the first axial hole 21 is embedded in the slot, thereby limiting the axial displacement between the second cover body 20 and the first cover body 10; when the first cover body 10 is peeled off, unscrewed or opened from the machine body or cup body, the first cover body 10 drives the second cover body 20 to open through the metal clip on the peripheral wall of the rotating column 11, so that the second cover body 20 can be opened conveniently.

[0057] In addition, in the embodiment of the present application, the first cover body 10 and the second cover body 20 are clamped together by using a metal clamping piece made of metal material. The metal clamping piece made of metal material can still maintain its shape and structure after repeated use and will not be deformed. It will not be deformed even when subjected to high temperature (for example, heating by a food processor) or vibration (for example, stirring by a food processor), and can well maintain the clamping state of the first cover body 10 and the second cover body 20, thereby effectively ensuring the stability of the clamping of the first cover body 10 and the second cover body 20 and improving the user experience.

[0058] It is understandable that the metal clip can be made of metal or alloy materials that are not easily deformed by heat or cold, such as aluminum alloy and stainless steel.

[0059] It should be noted that the above description only takes the setting of the rotating column 11 on the first cover body 10 as an example. Those skilled in the art can understand that the rotating column 11 can also be set on the second cover body 20. Correspondingly, the first axial hole 21 can be set on the first cover body 10. The setting method is the same or similar to the above method and will not be repeated in the embodiments of the present application.

[0060] In an embodiment of the present application, a rotating column 11 is provided on one of the first cover 10 and the second cover 20, and a first shaft hole 21 is provided on the other of the first cover 10 and the second cover 20. The rotating column 11 can be inserted into the first shaft hole 21 and rotate relative to the first shaft hole 21. Additionally, a metal clamping member is provided on the peripheral wall of the rotating column 11. When the rotating column 11 is inserted into the first shaft hole 21, the metal clamping member can be clamped with the edge of the first shaft hole 21, thereby preventing the rotating column 11 from moving out of the first shaft hole 21. Thus, the first cover 10 and the second cover 20 can be clamped together. By using a metal clamping member, the metal clamping member will not deform after long-term use, nor will it deform due to high temperature or other situations, thereby effectively ensuring the clamping between the first cover 10 and the second cover 20. Compared with the prior art, it can avoid the situation where the first cover 10 and the second cover 20 fall off due to the deformation of the buckle, improve the stability of the clamping between the first cover 10 and the second cover 20, and improve the user experience effect.

[0061] It can be understood that usually when cooking food, it may be necessary to stir or heat the food, resulting in some liquid food or steam possibly entering the gap between the first cover 10 and the second cover 20 through the first shaft hole 21 on the second cover 20. In order to facilitate the cleaning of the gap between the first cover 10 and the second cover 20, it is necessary to disassemble the first cover 10 and the second cover 20. In the embodiment of the present application, the metal clamping member is movably connected to the peripheral wall of the rotating column 11.

[0062] Specifically, an elastic member can be provided on the peripheral wall of the rotating column 11. For example, an installation hole is opened on the peripheral wall of the rotating column 11, and a compression spring or a spring piece is buried in the installation hole. The metal clamping member is movably connected to the rotating column 11 through the elastic member.

[0063] In some alternative ways, the metal clamping member can also be connected to the rotating column 11 by threads.

[0064] When it is necessary to disassemble the first cover 10 and the second cover 20 and clean the gap between the first cover 10 and the second cover 20, the metal clamping member can be moved, for example, by compressing the elastic member through a metal connecting member, thereby changing the distance that the metal connecting member protrudes from the peripheral wall of the rotating column 11, so that the rotating column 11 can move out of the first shaft hole 21; or, by screwing the metal clamping member, the metal clamping member can be screwed off from the peripheral wall of the rotating column 11, and then the first cover 10 and the second cover 20 are disassembled.

[0065] In this way, the disassembly of the first cover 10 and the second cover 20 can be facilitated, and the dirt entering the gap between the first cover 10 and the second cover 20 can be conveniently cleaned.

[0066] Optionally, referring to Figure 1 as shown, the metal snap member is a metal snap ring 30, and both ends of the metal snap ring 30 are rotatably connected to the peripheral wall of the rotating column 11, so that the metal snap ring 30 can rotate between the axial direction and the radial direction of the rotating column 11;

[0067] Specifically, in the embodiment of the present application, the metal snap ring 30 may be an arc structure, and its radian is approximate or the same as that of the rotating column 11. When the metal snap ring 30 rotates to the radial direction of the rotating column 11, the metal snap ring 30 surrounds the outer periphery of the rotating column 11.

[0068] Referring to Figures 2 - 4 as shown, Figure 2 is Figure 1 a partial enlarged schematic view of the position A in Figure 3 is Figure 2 a partial enlarged schematic view of the position B in Figure 4 is a schematic structural view of the metal snap ring in the cover assembly provided by the embodiment of the present application. A first boss 112 is provided on the peripheral wall of the rotating column 11. When the metal snap ring 30 rotates to the radial direction of the rotating column 11, the first boss 112 can be snap-connected to the metal snap ring 30 to prevent the metal snap ring 30 from rotating.

[0069] Specifically, referring to Figure 3 as shown, in the embodiment of the present application, the first boss 112 may be integrally formed with the peripheral wall of the rotating column 11. In some possible ways, the first boss 112 may also be fixed on the peripheral wall of the rotating column 11 through connecting components such as bolts, screws or screws.

[0070] In this way, when the metal snap ring 30 rotates to a position parallel or approximately parallel to the radial position of the rotating column 11, the metal snap ring 30 is snap-connected and limited by the first boss 112 and can abut against the hole edge of the first shaft hole 21, thereby limiting the axial displacement between the first cover 10 and the second cover 20. When the metal snap ring 30 is rotated to a position parallel or approximately parallel to the axial direction of the rotating column 11, the rotating column 11 can be taken out from the first shaft hole 21, which is convenient for the disassembly between the first cover 10 and the second cover 20 and convenient for cleaning the gap between the first cover 10 and the second cover 20.

[0071] Specifically, in the embodiment of the present application, the metal snap ring 30 may be bent from steel wire, steel bar or iron wire into a semi-circular structure with the same or approximate radian as that of the rotating column 11. The bent portion 31 may be formed by further bending at both ends of the metal snap ring 30, and the bent portion 31 may specifically be bent along the diameter of the semi-circular structure towards the center of the circle.

[0072] Those skilled in the art can understand that since the metal snap ring 30 is bent into a semi-circular arc structure by steel wire, steel bar or iron wire, the metal snap ring 30 has a certain elasticity in the radial direction of the semi-circle. When it is necessary to disassemble the first cover body 10 and the second cover body 20, the metal snap ring 30 can be pulled along the radial direction of the metal snap ring 30, and the deformation of the metal snap ring 30 in the radial direction can cross the first boss 112, so as to rotate to the axial direction of the rotating column 11.

[0073] Optionally, as shown in Figures 2 - 4 In the embodiment of the present application, the circumferential wall of the rotating column 11 has second shaft holes 111 provided at both radial ends of the rotating column 11. Both ends of the metal snap ring 30 have bent portions 31, and the bent portions 31 can be inserted into the second shaft holes 111 and are rotatably connected to the second shaft holes 111.

[0074] In this way, during installation, the elastic force of the metal snap ring 30 itself can be relied on to install the bent portions 31 at both ends into the second shaft holes 111.

[0075] Among them, the second shaft holes 111 can be integrally formed with the rotating column 11. In some possible examples, the second shaft holes 111 can also be formed by the way of digging holes.

[0076] In this way, the integrity of the metal snap ring 30 can be ensured. In addition, it is convenient to install the metal snap ring 30 on the circumferential wall of the rotating column 11, and the installation efficiency is improved.

[0077] Optionally, as shown in Figure 4 In the embodiment of the present application, at least one of the two bent portions 31 has an anti-disengagement hook 311, and the anti-disengagement hook 311 is bent relative to the bent portion 31.

[0078] Specifically, as shown in Figure 4 The anti-disengagement hook 311 can be formed by bending from the end of the bent portion 31, and specifically can be bent toward one side of the metal snap ring 30.

[0079] In this way, after the metal snap ring 30 is installed on the rotating member 11, the anti-disengagement hook 311 can be engaged with the inner circumferential wall of the rotating column 11, so as to limit the displacement of the bent portion 31 in the axial direction of the second shaft hole 111, and the bent portion 31 can be prevented from moving out of the second shaft hole 111, improving the stability of the installation of the metal snap ring 30.

[0080] Optionally, in the embodiment of the present application, the anti-disengagement hook 311 can be provided on one of the bent portions 31, or the anti-disengagement hook 311 can be provided on both of the bent portions 31. The embodiment of the present application does not make any limitation in this regard.

[0081] In some alternative design embodiments of the present application, the second shaft hole 111 and the first boss 112 are arranged axially offset along the rotation column 11, and the second shaft hole 111 is located on one side of the first boss 112 away from the end face of the rotation column 11.

[0082] Specifically, in the embodiments of the present application, the second shaft hole 111 is located on one side of the first boss 112 facing away from the rotation column 11.

[0083] It can be understood that, for the convenience of the rotation of the metal snap ring 30, the second shaft hole 111 and the first boss 112 are also arranged circumferentially offset along the rotation column 11.

[0084] In the embodiments of the present application, by arranging the second shaft hole 111 and the first boss 112 axially offset along the rotation column 11, and arranging the second shaft hole 111 on one side of the first boss 112 facing away from the end face of the rotation column 11, in this way, when rotating the metal snap ring 30, it can be ensured as much as possible that the metal snap ring 30 is parallel to the rotation column 11 in the radial direction, thereby increasing the contact area between the metal snap ring 30 and the edge of the first shaft hole 21, that is, increasing the buckling area and improving the buckling stability.

[0085] In a specific example, the quadrant point on the side of the end face of the second shaft hole 111 facing the rotation column 11 and the side wall on the side of the end face of the first boss 112 facing away from the rotation column 11 are in the same plane.

[0086] It should be noted that those skilled in the art can understand that in the embodiments of the present application, the description of the distance has a certain processing error in actual production, and for those skilled in the art, this processing error can be ignored.

[0087] Optionally, referring to Figure 1 and Figure 4 As shown, in the embodiments of the present application, the metal snap ring 30 has a protruding portion 32, and the protruding portion 32 is arranged circumferentially offset from the first boss 112 along the rotation column 11.

[0088] Specifically, in the embodiments of the present application, the protruding portion 32 can be located in the middle of the arc-shaped metal snap ring 30. The arc of the protruding portion 32 can be smaller than the overall arc of the metal snap ring 30, so that the protruding portion 32 protrudes radially outward along the arc-shaped metal snap ring 30.

[0089] In this way, referring to Figure 1As shown, when the metal snap ring 30 rotates to be parallel or approximately parallel to the radial direction of the rotating column 11, there will be a small notch or gap between the protruding portion 32 and the peripheral wall of the rotating column 11, which can facilitate the entry of the user's finger and the radial pulling of the protruding portion 32, causing the metal snap ring 30 to deform radially and thus separate from the first boss 112, that is, facilitating the disassembly of the first cover 10 and the second cover 20.

[0090] Disposing the first boss 112 and the protruding portion 32 out of alignment along the circumferential direction of the rotating column 11 can effectively ensure the clamping and limiting of the metal snap ring 30 by the first boss 112.

[0091] Optionally, referring to Figures 3 - 6 as shown in Figure 5 is a schematic diagram of the assembly process of the first cover and the second cover in the cover assembly provided by the embodiment of the present application, Figure 6 is a schematic exploded view of the first cover and the second cover in the cover assembly provided by the embodiment of the present application. In the embodiment of the present application, the hole wall of the first shaft hole 21 has a through groove 211, and the through groove 211 is arranged along the axial direction of the first shaft hole 21. The two ends of the metal snap ring 30 and the first boss 112 can pass through the first shaft hole 21 along the through groove 211.

[0092] Specifically, in the embodiment of the present application, the through groove 211 can be integrally formed with the first shaft hole 21, or after the first shaft hole 21 is formed, the through groove 211 is formed on the hole wall of the first shaft hole 21 by means of grooving.

[0093] Referring to Figure 6 as shown in

[0094] Optionally, in the embodiment of the present application, there are two first bosses 112, and the two first bosses 112 are respectively located on both sides of the metal snap ring 30.

[0095] In this way, after the user inserts the rotating column 11 into the first shaft hole 21, the user can rotate in any of the two directions at will, which is convenient for the user experience and improves the installation and buckling efficiency.
