[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] refer to Figures 1 to 7 As shown, a juice extraction linkage mechanism for a food processor includes a base assembly 1, a food processor cup 2, and a lid assembly 3. The lid assembly 3 is adapted to cover the mouth of the food processor cup 2 and encloses and defines the mixing chamber 201. The bottom of the food processor cup 2 is rotatably connected to a mixing blade assembly 6. The base assembly 1 mainly includes components such as a motor 11, a rotating shaft 12, and a main control board 13, as well as auxiliary parts required for installing and fixing these components. All the components involved are existing technologies and can be selected and arranged as needed. The cooking cup 2 is detachably fixed to the base assembly 1.

[0025] The lower end of the rotating shaft 12 is connected to the motor 11, the upper end of the rotating shaft 12 passes through the bottom of the cup, and the end of the rotating shaft 12 extends into the inner cavity of the food preparation cup 2 and is directly connected to the stirring blade assembly 6 for transmission, or it can be connected to the bottom end of the stirring blade assembly 6 through a coupling-like structure; the motor 11 drives the stirring blade assembly 6 to rotate.

[0026] The bottom of the mixing chamber 201 is provided with a juice outlet 202, and a juice outlet plug 16 is sealed at the juice outlet 202; the bottom of the food processing cup 2 is connected to a flow guide component 17 that extends radially outward, and the flow guide component 17 defines a juice outlet channel 171 that communicates with the juice outlet 202; a switch control device 18 that can be manually operated outside the machine is connected to the flow guide component 17, and the switch control device 18 works in conjunction with the juice outlet plug 16 to open or close the juice outlet 202.

[0027] In this embodiment, the switch control device 18 includes a manual operating component 19 and a linkage traction rod 20. The manual operating component 19 is rotatably connected to the flow guiding component 17. One end of the linkage traction rod 20 is fixedly connected to the manual operating component 19, and the juice drain plug 16 is fixedly connected to the other end of the linkage traction rod 20. Combining the above structure, the food processor utilizes a juice discharge linkage mechanism consisting of a juice discharge plug 16, a manual operation component 19, and a linkage traction rod 20. This allows the mixing chamber 201 and the juice discharge channel 171 to operate independently, preventing the juice in the mixing chamber 201 from falling into the juice discharge channel 171 before being discharged. When heating is required, this avoids the situation where the juice in the juice discharge channel 171 cannot be fully heated, resulting in cleaner and more hygienic food. Cleaning is also easier after use, and it effectively prevents waste liquid from accumulating in the juice discharge channel 171 at the front end of the juice discharge plug 16.

[0028] The manual operating component 19 includes a rotating shaft 191 for rotatable connection, and a drive plate 192 and a baffle 193 located on both sides of the rotating shaft 191. The drive plate 192 and the baffle 193 are arranged in a V-shape in the juice drainage channel 171. One end of the linkage traction rod 20 is connected to the back side of the baffle 193. By swinging the drive plate 192, the baffle 193 is driven to drive the linkage traction rod 20, causing the juice drain plug 16 to swing downward to open the juice drain port 202.

[0029] Moreover, the top surface of the flow guide component 17 is provided with an operation port 172 for an open juice discharge channel 171. The drive plate 192 is exposed outside the machine through the operation port 172, which allows the user to use the drive plate 192 to drive the baffle 193 and the baffle 193 to swing outside the machine, thereby controlling the opening and closing of the juice discharge plug 16 and the juice discharge port 202. When the drain port 202 is open, the drive plate 192 will flip out of the operation port 172. At this time, the baffle 193 replaces the drive plate 192 and moves to the position of the operation port 172 and blocks part of the drain channel 171. This structure can block part of the open space above the drain channel 171 through the baffle 193, preventing the juice that is initially drained from splashing out through the operation port 172 when it flows out (the pressure of the juice is relatively large when it is initially drained, and it will collide with the guide component 17 downwards and then splash upwards). On the other hand, it can also prevent the splashed juice from falling back into the drive plate 192 after touching the surface of the fingers holding the drive plate 192. When the drain port 202 is closed, the baffle 193 intercepts the drain flow channel 171 but does not seal it. The drive plate 192 is flush with or parallel to the operation port 172. In this way, the user can more intuitively know whether the switch control device 18 has been reset. When the switch control device 18 is reset, it means that the drain port 202 is closed by the drain plug 16.

[0030] The manual operating component 19 is provided with a magnet 21 that moves with its moving end. The base assembly 1 is provided with a magnetic control switch 25 located near the magnet 21. The magnetic control switch 25 is used to at least turn on and off part of the working circuit of the food processor. Through the cooperation of the magnetic control switch 25 and the magnet 21, the main control board can determine whether the food processor cup 2 is installed on the base assembly 1. On the other hand, when the user operates the switch control device 18 to drain the juice, the magnet 21 and the magnetic control switch 25 make contact and cooperate magnetically. The main control board can immediately stop the operation of the motor 11 and / or the heating plate 15 to prevent the juice from spraying out from the drain channel 171.

[0031] The magnetic switch 25 can be a Hall switch or a reed switch.

[0032] The linkage traction rod 20 includes an inclined curved arm body 2001. One end of the curved arm body 2001 extends laterally and forms a connector 2002. A first connecting hole 2003 is provided on the connector 2002. A cavity for positioning the connector is provided on the back side of the baffle 193. A first through hole 1931 is provided in the baffle 193 within the cavity. Fastening units such as screws pass through the first through hole 1931 and the first connecting hole 2003 to fasten the linkage traction rod 20 to the baffle 193. One end of the crank arm body 2001 extends vertically and is provided with a sleeve joint 161. The sleeve joint 161 is detachably fitted with an elastic sealing element 162. The sealing element 162 and the sleeve joint 161 form a drain plug 16. The sealing element 162 can be elastically fitted to achieve a seal, while the sleeve joint 161 can maintain the shape of the sealing element 162 to prevent the sealing element 162 from being over-deformed or loosened from the crank arm body 2001.

[0033] The sealing element 162 includes a sealing body 1621, which is interference-fitted with the drain port 202. After being inserted into the drain port 202, the sealing body 1621 forms a first layer of sealing contact. The top of the sealing body 1621 is provided with an inclined guide surface 1622, which helps the sealing body 1621 to be inserted into the drain port 202. A limiting ring 1623 extends from the periphery of the sealing body 1621. The limiting ring 1623 can seal against the bottom surface of the drain port 202, forming a second layer of sealing contact. The double sealing contact improves the sealing effect and prevents leakage from the drain port 202.

[0034] The top surface of the flow guide component 17 is provided with a flow channel inlet 173 that connects the drain outlet 202 and the drain channel 171. A sealing ring 22 is connected to the flow guide component 17 and surrounds the flow channel inlet 173. The sealing ring 22 seals against the joint surface between the food preparation cup 2 and the flow guide component 17, sealing the gap between the flow guide component 17 and the food preparation cup 2 to prevent juice from leaking out of the flow guide component 17 and causing juice to accumulate in the gap and cause bacterial growth.

[0035] The blending cup 2 includes a cup body 23, a heating plate 15, and a cup base 24. The heating plate 15 is fitted to the lower opening of the cup body 23, and the drain outlet 202 is opened on the heating plate 15. The cup base 24 is fitted to the bottom of the cup body 23 and is provided with an assembly cavity 241. The flow guide component 17 is fastened to the assembly cavity 241. The heating plate 15 enables the blender to achieve the heating function, and by fitting the flow guide component 17 into the assembly cavity 241, the height of the bottom protrusion of the blending cup 2 can be reduced, making the blending cup 2 compact.

[0036] In this embodiment, the flow guide component 17 has connecting ears 174 with second through holes 175 extending on both sides. The assembly cavity 241 is provided with a limiting groove 242 that matches the position of the connecting ears 174. When the connecting ears 174 and the limiting groove 242 are engaged, the flow guide component 17 can be restricted from sliding back and forth. The limiting groove 242 is provided with a second connecting hole 243 corresponding to the second through hole 175. After fastening units such as screws pass through the second through hole 175 and the second connecting hole 243, the flow guide component 17 is fastened to the cup holder 24.

[0037] The top surface of the base assembly 1 is provided with a positioning groove 101 that is positioned to cooperate with the bottom of the cooking cup 2. One side of the positioning groove 101 is provided with a positioning notch 102 that avoids the flow guiding component 17. A magnetic switch 25 is provided on the inner side of one side wall of the positioning notch 102. The cooperation between the flow guiding component 17 and the positioning notch 102 can play a role in preventing mistakes and improve the assembly efficiency of the cooking cup 2.
