[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0027] See also Figure 1-7This embodiment provides a chef, comprising an upper housing 1 and a lower housing 2, connected by a rotating mechanism 3. A limit cover 11 is mounted on the lower end of the upper housing 1. The limit cover 11 has a downwardly inclined guide portion 113. An arcuate guide rail 114 is provided on the limit cover 11. The arcuate guide rail 114 curves in the same direction as the guide portion 113, i.e., the arcuate guide rail 114 curves downward in an arc shape. The arcuate guide rail 114 includes a locking hole 1141 and a slideway 1142. The locking hole 1141 communicates with the slideway 1142, and the locking hole 1141 is located at both ends of the slideway 1142. A locking shaft 21 passes through the arcuate guide rail 114 and is secured to the lower housing 2, further connecting the upper and lower housings 2. The locking shaft 21 is provided with a groove 2111. When the groove 2111 is located within the locking hole 1141, the upper housing 1 can rotate relative to the lower housing 2, allowing the upper housing 1 to be lifted upward or closed downward. When the groove 2111 is away from the locking hole 1141, the upper housing 1 and the lower housing 2 are locked, and the upper housing 1 and the lower housing 2 are fixed and cannot rotate.

[0028] The food processor of this embodiment controls the movement of the locking shaft 21 by interfacing the groove 2111 of the locking shaft 21 with the locking hole 1141 in the curved guide rail 114. When the groove 2111 of the locking shaft 21 is located in the locking hole 1141, the locking shaft 21 can slowly slide downward along the guide 113, leveraging its own gravity and the thrust of the rotating mechanism, due to the downwardly inclined guide rail 114 and the curved guide rail 114. This causes the upper housing 1 to lift upward, allowing the food processor to lift its head. To close the upper and lower housings 1 and 2, the top of the upper housing 1 is pressed while the locking shaft 21 is simultaneously moved, positioning the groove 2111 of the locking shaft 21 within the locking hole 1141. This allows the upper housing 1 to close downwardly with the lower housing 2. During the sliding process of the arc guide rail 114, the locking shaft 21 of the food processor of this embodiment slides up and down along the inclined direction of the guide part 113, which has a limiting guiding effect on the movement trajectory, can reduce the impact during the flipping process, reduce the vibration of the upper shell 1 during the lifting and closing flipping, and avoid the problem of the guide rail loosening during long-term use.

[0029] For further information, see Figure 2 and Figure 4The limiting cover 11 includes a connecting seat 111 and a cover body 112. The connecting seat 111 is fixedly connected to the upper shell 1 and can be achieved by screws or integral molding. The specific connection method is not limited. The cover body 112 has an inner cavity. A driving mechanism such as a motor is provided in the upper shell 1. The motor is located in the cover body 112. The guide portion 113 is provided at one end of the cover body 112 away from the connecting seat 111. The guide portion 113 has an arc chamfer formed by tilting from the side wall of the cover body 112 to the bottom.

[0030] In this embodiment, two arc-shaped guide rails 114 are provided, which are symmetrically arranged on the side walls of the cover body 112, further improving the stability of the upper shell 1 and the lower shell 2 during the flipping process.

[0031] For further information, see Figure 2 、 Figure 5 and Figure 6 The limiting cover 11 is provided with a groove 115, in which the guide rail plate 12 is embedded. The guide rail plate 12 overlaps with the arc-shaped guide rail 114, that is, the shape of the guide rail plate 12 is the same as that of the arc-shaped guide rail 114. When the inner cavity of the guide rail plate 12 is installed in the groove 115, the guide rail plate 12 completely overlaps with the arc-shaped guide rail 114. By arranging the guide rail plate 12 embedded in the limiting cover 11, the installation space can be reduced.

[0032] Specifically, the limit cover 11 is provided with a reinforcement portion 116, and the guide rail plate 12 is provided with a through hole 121. The reinforcement portion 116 is located on the back of the groove 115. The fixing member 4 passes through the through hole 121 and is fixed on the reinforcement portion 116, thereby better fixing the guide rail plate 12 in the groove 115.

[0033] For further information, see Figure 2-5 The connecting seat 111 is provided with a positioning groove 1111, and the lower shell 2 is provided with a protrusion 22. When the upper shell 1 and the lower shell 2 are closed, the protrusion 22 is inserted into the positioning groove 1111, so that the upper shell 1 and the lower shell 2 are positioned when closed.

[0034] Furthermore, the positioning groove 1111 is provided with a through hole 1112, the protrusion 22 is provided with a push rod 221, and a micro switch 13 is mounted on the connecting base 111. The micro switch 13 is located within the upper housing 1, and the push rod 221 passes through the through hole 1112 and abuts against the micro switch 13. In this embodiment, the micro switch 13 has a trigger portion, which is a prior art structure. The micro switch 13 is electrically connected to the motor. When the upper housing 1 and the lower housing 2 are closed, the top cover 221 abuts the trigger portion of the micro switch 13, the micro switch 13 is in the on state, and the motor can operate.

[0035] When the upper shell 1 is flipped upward, the top rod 221 no longer abuts against the micro switch 13. At this time, the trigger part of the micro switch 13 abuts, and the micro switch 13 is in a power-off state, disconnecting the motor from the power supply, thereby preventing the food processor from being in working state when the upper shell 1 is flipped upward.

[0036] See also Figure 2 、 Figure 3 、 Figure 6 and Figure 7 The locking shaft 21 includes a limiting shaft 211 and a pressing member 212. An elastic member 213 is sleeved on one end of the limiting shaft 211. The pressing member 212 is connected to the limiting shaft 211 and abuts against the elastic member 213. The pressing member 212 extends to the exterior of the lower housing 2. A limiting member 214 is provided on the other end of the limiting shaft 211. The grooves 2111 are located at both ends of the limiting shaft 211 and match the number of the guide rail plates 12 or the arcuate guide rails 114.

[0037] In this embodiment, the limiting shaft 211 passes through the mounting hole 24 on the lower shell 2, and the pressing piece 214 is fixedly connected to the limiting shaft 211. The user drives the limiting shaft 211 to move inward by pressing the pressing piece 212, and the groove portion 2111 is located in the locking hole 1141. At this time, the limiting shaft 211 can slide up and down along the inclined direction of the guide portion 113. When the limiting shaft 211 slides from the locking hole 1141 at one end to the locking hole 1141 at the other end, the restoring force of the elastic piece 213 drives the limiting shaft 211 outward, thereby making the groove portion 2111 away from the locking hole 1141, and the limiting shaft 211 cannot slide, thereby locking the upper shell 1 and the lower shell 2.

[0038] See also Figure 2 and Figure 4The rotation mechanism 3 includes a torsion spring 31 and a rotation shaft 32. A support 23 is provided in the lower housing 2. The torsion spring 31 is sleeved on the rotation shaft 32. The limiting cover 11 is provided with a connecting ear 117. Both ends of the rotation shaft 32 pass through the connecting ear 117 and are then clamped on the support 23. The torsion spring 31 drives the upper housing 1 to rotate relative to the lower housing 2. When the user presses the pressing member 212, the limiting shaft 211 slides in the slideway 1142. At this time, the torsion spring 31 also drives the other side of the upper housing 1 to rotate upward relative to the upper housing 2.
