[0063] The kettle cover 101 in this embodiment can be snap-fitted on the connecting plate 11, or the kettle cover 101 is fixed on the connecting plate 11 by bolts. Specifically, it can be determined according to the actual situation, and this embodiment of the specification does not limit this.

[0064] During use, the first driving assembly 13 drives the kettle body 103 to move along the X-axis. Since the kettle cover 101 is fixed to the connecting plate 11, the kettle body 103 can slide parallel to the kettle lid 102 on the kettle cover 101, thus facilitating the opening of the kettle body 103.

[0068] Referring to Figure 1 As shown, this embodiment includes at least two first driving assemblies 13. The two first driving assemblies 13 are respectively arranged on the left and right sides of the connecting plate 11, and the structures of the two first driving assemblies 13 are the same. Among them, the first support rod 131 on each first driving assembly 13 is horizontally placed along the X-axis direction. One end of the second support rod 132 is vertically fixed on the first support rod 131, and the other end is connected to the connecting plate 11 by bolts.

[0069] One end of the guide rod 134 facing the connecting plate 11 can be connected to the kettle body 103 by bolts. The first driving member 133 can be fixed on the first support rod 131 by bolts, and the first driving member 133 is connected to the guide rod 134 and can drive the guide rod 134 to move along the X-axis direction. Since the guide rod 134 is connected to the kettle body 103, when the guide rod 134 moves along the X-axis direction, the kettle body 103 can be synchronously driven to move along the X-axis direction, and further the kettle body 103 slides parallel to the kettle lid 102 on the kettle cover 101 to facilitate the opening of the kettle body 103.

[0070] It should be noted that the structure of the first driving component described above is only an example. In other alternative solutions, other structures can also be adopted. For example, the first driving component includes a cylinder, and the guide rod is driven to move by the cylinder. The present application does not impose special restrictions on the specific structure of the first driving component, as long as the above structure can achieve the purpose of the present application.

[0075] The second driving component in this embodiment can be a cylinder, an electric telescopic rod, a ball screw mechanism, etc. For the convenience of description below, it is taken as an example that the second driving component is a ball screw mechanism for description.

[0076] In this embodiment, the second driving component 14 can be connected to the guide rod 134 far from the connecting plate 11 by bolts, and the lead screw nut 141 on the second driving component 14 and the kettle body 103 can be connected together by bolts.

[0077] During use, the second driving component 14 drives the lead screw nut 141 to move along the Y-axis direction. At this time, the lead screw nut 141 drives the kettle body 103 to move along the Y-axis direction, so that the kettle body 103 can approach or move away from the kettle lid 102 in the Y-axis direction.

[0078] When the kettle body 103 moves away from the kettle lid 102 in the Y-axis direction, the first driving member 133 is used to drive the guide rod 134 to move in the X-axis direction, and the guide rod 134 then drives the second driving assembly 14 to move in the X-axis direction. Since the second driving assembly 14 is connected to the kettle body 103, at this time, the kettle body 103 can be misaligned relative to the kettle lid 102; when it is necessary to align the kettle body 103 with the kettle lid 102, the above-mentioned away steps can be controlled in reverse, which will not be elaborated here.
