Description

Technical Field

[0001] This invention relates to the field of pot lids, and more particularly to an automatic cooking pot lid adapted to common woks. Background Technology

[0002] In existing technologies, pot lids with stir-frying functions can only be used with pots of a matching size. If used with pots of other sizes, size incompatibility occurs, preventing stir-frying. Furthermore, existing automatic stir-fry pot lids are prone to tipping over during cooking, causing food to be carried out of the pot by the stirring mechanism and splatter outwards. When stir-frying hard, bone-in foods like ribs, the stirring mechanism may be lifted by the food upon contact, causing the lid to move upwards along with it, disengaging the lid from the pot and interrupting the cooking process. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the present invention provides an automatic wok lid that is compatible with most woks. It can be used with woks of different sizes and can ensure the fit between the wok and the lid during cooking, so as to ensure that the cooking process can proceed smoothly.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] The present invention provides an automatic stir-fry pot lid adapted to a common wok, comprising a pot lid body, a stir-frying component at the bottom of the pot lid body, and a driving mechanism on the pot lid body for driving the stir-frying component to stir-fry food. The pot lid body has a working cavity inside, and a locking module is provided in the working cavity. The locking module includes a locking driving mechanism and multiple locking components. The locking components are circumferentially distributed, and the outer ends of the locking components extend out of the outer edge of the pot lid body. The locking driving mechanism is used to drive the locking components to lock / unlock the pot body.

[0006] In this design, after the lid body is placed at the opening of the pot, the locking mechanism drives the locking element to move into the working cavity. The locking element first contacts the edge of the pot and then abuts against it, locking the lid body and the pot body together. After locking, the driving mechanism drives the stirring element to stir-fry the food. During the stir-frying process, because the locking element has locked the pot body and lid body together, the lid body and the pot body remain locked together, and the lid body will not move due to resistance from the stirring element. When it is necessary to unlock the lid body and the pot body, the locking mechanism drives the locking element to move out of the working cavity, and the locking element no longer contacts the edge of the pot body, thus unlocking the lid body and the pot body.

[0007] Preferably, the locking element is U-shaped and includes a first horizontal portion located inside the working cavity and a second horizontal portion located outside the working cavity. The first and second horizontal portions are arranged parallel to each other. The first horizontal portion extends beyond the outer edge of the lid body, and its outer end is connected to the outer end of the second horizontal portion via a vertical portion. The first horizontal portion is positioned above the second horizontal portion. During the locking process, the first horizontal portion moves into the working cavity, and the first horizontal portion, through the vertical portion, drives the second horizontal portion to move towards the pot body, causing the second horizontal portion to abut against the pot body, thus completing the locking of the lid body and the pot body.

[0008] Preferably, the locking drive mechanism includes a locking disc and a locking disc drive mechanism. The locking disc is coaxial with the pot lid body. The locking disc has multiple arc-shaped grooves penetrating it, distributed circumferentially. The arc-shaped grooves extend outward from the center of the locking disc, and each groove corresponds to a locking element. A sliding rod is installed within each arc-shaped groove, and the sliding rod is fixedly connected to a corresponding first horizontal part via a locking connector. The locking disc drive mechanism drives the locking disc to rotate. When the locking disc rotates, the sliding rod slides within the arc-shaped groove, and the sliding motion of the sliding rod drives the corresponding first horizontal part to move via the locking connector.

[0009] Preferably, the pot lid body includes a top cover and a bottom cover arranged from top to bottom, the working cavity is located between the top cover and the bottom cover, the locking disc drive mechanism includes a switch plate and a locking reset mechanism, the top of the top cover has a through arc-shaped switch groove, the switch plate includes a handle and a lever, the lever extends into the arc-shaped switch groove, the top of the lever is connected to the handle, a retaining plate is provided on the inner side of the bottom of the lever, the lever can move back and forth in the arc-shaped switch groove, and the locking reset mechanism includes an arc-shaped rack and a locking mechanism. The fixed plate on the fixed plate has an arc-shaped rack located at the bottom of the top cover. The arc-shaped rack is located inside the arc-shaped switch groove and is coaxial with the locking plate. The locking plate is also provided with a sliding groove, and a locking slider that can slide along the groove is provided in the groove. The fixed plate is located inside the groove. The locking plate matches the arc-shaped rack. The locking slider is fixedly connected to the locking plate through an intermediate connector. A spring is provided between the inner side of the locking slider and the outer side of the fixed plate. The spring is used to pull the locking plate to make the locking plate engage with the arc-shaped rack.

[0010] The handle moves the lever, causing it to slide left and right within the arc-shaped switch slot. During this sliding motion, the lever moves the locking plate, which in turn rotates the locking slider via the intermediate connector. When the locking slider rotates the locking disc counter-clockwise to its immovable position, releasing the handle allows the spring to pull the locking plate into the teeth of the arc-shaped rack, locking the pot body and lid. To unlock the pot body and lid, pull the handle outwards. After pulling the handle outwards, the locking plate no longer engages with the teeth of the arc-shaped rack. The handle then moves the locking plate clockwise, causing the locking slider to move the locking disc clockwise, moving the locking element outwards, thus unlocking the pot body and lid.

[0011] Preferably, the driving mechanism includes a driving module and a stirring connecting column. The top of the stirring connecting column is connected to the output end of the driving module, and the bottom of the stirring connecting column is connected to the stirring component. The driving module is used to drive the stirring connecting column to rotate.

[0012] Preferably, the bottom of the stirring connecting column has a vertical cavity, and a connecting rod is slidably connected within the cavity. The bottom of the connecting rod is connected to the stirring component. The outer wall of the stirring connecting column has a through hole communicating with the cavity, and a bolt is threaded into the through hole. The inner side of the bolt abuts against the outer wall of the connecting rod. When the height of the stirring component needs to be adjusted, the bolt is rotated so that it no longer abuts against the connecting rod. At this time, the height of the stirring component can be changed by stretching the connecting rod. When the appropriate height is reached, the bolt is rotated again to abut against the connecting rod, thus locking the bolt.

[0013] Preferably, the driving mechanism further includes an adjustment mechanism, which includes a horizontally arranged base plate located between the pot lid body and the stir-frying component. The base plate is sleeved on the outer wall of the stir-frying connecting column and can move up and down along the outer wall of the stir-frying connecting column. Adjustment plates are symmetrically and vertically arranged at both ends of the base plate. Adjustment grooves are symmetrically arranged on the left and right sides of the base plate. A connecting rod that can slide left and right along the adjustment groove is arranged in the adjustment groove. The bottom of the connecting rod is fixedly connected to the stir-frying component. The connecting rod is vertically arranged. A screw rod is provided through the adjustment plate. The screw rod is fixedly connected to the top of the connecting rod on the corresponding side. A nut is threaded onto the screw rod. The nut is located outside the adjustment plate and is rotatably connected to the adjustment plate. The bottom of the connecting rod is slidably connected to the stir-frying component.

[0014] When the stir-frying component needs to be adjusted left or right, rotate both nuts simultaneously. Adjust the length of the screw extending from the adjustment plate on the corresponding side by adjusting the screw position. This changes the position of the screw and moves the connecting rod, which in turn moves the stir-frying component.

[0015] Preferably, the top of the pot lid body is also provided with an observation tube that runs from top to bottom through the pot lid body, and the top of the observation tube is fitted with a top cover.

[0016] Preferably, the drive module includes a drive motor, which is disposed on the top of the lid. The output shaft of the drive motor passes through the lid body and is detachably connected to the stir-fry connecting column. The output shaft of the drive motor is coaxial with the stir-fry connecting column and the lid body.

[0017] Preferably, the drive motor is provided with a protective housing, and a handle is provided on one side of the protective housing.

[0018] The beneficial effects of this invention are: the locking module can lock / unlock the lid body and the pot body; the adjustment mechanism can adjust the left and right position of the stir-frying component; the stir-frying connecting column and the connecting rod can extend and retract to adjust the vertical height of the stir-frying component; the handle on one side of the protective shell can make it convenient for the user to lift the lid body.

[0029] The driving mechanism 2 includes a driving module 21 and a stirring connecting column 22. The top of the stirring connecting column 22 is connected to the output end of the driving module 21, and the bottom of the stirring connecting column 22 is connected to the stirring component 11. The driving module 21 is used to drive the stirring connecting column 22 to rotate. The bottom of the stirring connecting column 22 has a vertical cavity, and a connecting rod 23 is slidably connected in the cavity. The bottom of the connecting rod 23 is connected to the stirring component 11. The outer wall of the stirring connecting column 22 has a through hole communicating with the cavity. A bolt is threaded into the through hole, and the inner side of the bolt abuts against the outer wall of the connecting rod 23.

[0030] The driving mechanism 2 also includes an adjustment mechanism 4, which includes a horizontally arranged base plate 41. The base plate 41 is located between the pot lid body 1 and the stir-frying component 11. The base plate 41 is sleeved on the outer wall of the stir-frying connecting column 22 and can move up and down along the outer wall of the stir-frying connecting column 22. Adjustment plates are symmetrically and vertically arranged at both ends of the base plate 41. Adjustment grooves 42 are symmetrically arranged on the left and right sides of the base plate. A connecting rod 43 that can slide left and right along the adjustment groove 42 is arranged in the adjustment groove 42. The bottom of the connecting rod 43 is fixedly connected to the stir-frying component 11. The connecting rod 43 is vertically arranged. A screw 44 is provided through the adjustment plate.

[0031] The top of the pot lid body 1 is also provided with an observation tube 5 that runs from top to bottom through the pot lid body 1, and the top of the observation tube 5 is fitted with a top cover.

[0032] The drive module 21 includes a drive motor, which is located on the top of the lid. The output shaft of the drive motor passes through the lid body 1. The output shaft of the drive motor is detachably connected to the stir-fry connecting post 22. The output shaft of the drive motor is coaxial with the stir-fry connecting post 22 and the lid body. The drive motor is provided with a protective shell, and a handle is provided on one side of the protective shell.

[0033] In this design, when stir-frying food in the wok, the lid is placed at the opening of the wok body. The handle is then pulled outwards and rotated counter-clockwise. Pulling the handle outwards moves the lever and locking plate outwards, while the locking plate, via the intermediate connector, moves the locking slider outwards within the groove. This sliding of the locking slider stretches the spring. Simultaneously, the handle moves the lever counter-clockwise within the arc-shaped switch groove, causing the locking plate to rotate counter-clockwise. The counter-clockwise rotation of the locking plate moves the sliding rod inwards within the arc-shaped groove. The sliding rod, via the locking connector, moves the corresponding first horizontal part inwards. The first horizontal part, via the vertical part, moves the second horizontal part inwards. During this inward movement, the second horizontal part first contacts the wok body and then abuts against it. This contact-then-abut locking process can be implemented for woks of different sizes.

[0034] After the lid body and the pot body are locked together, the drive motor is started. The output shaft of the drive motor drives the stir-frying component to rotate through the stir-frying connecting column, so that the stir-frying component stirs the food.

[0035] Different sizes of woks have different depths. To ensure that the stir-frying parts fit the wok body, rotate the bolt so that the inside of the bolt no longer abuts against the outer wall of the connecting rod. At this time, the user can manually pull the connecting rod to adjust the height of the stir-frying parts. After adjustment, rotate the bolt so that the inside of the bolt abuts against the outer wall of the connecting rod again to lock the connecting rod.

[0036] When in use, the stir-frying component needs to be adjusted in the left and right directions to meet the stir-frying requirements of some foods. At the same time, rotate the two nuts to adjust the length of the screw extending from the adjustment plate on the corresponding side. This changes the position of the screw and moves the connecting rod, which in turn moves the stir-frying component in the left and right directions.

[0037] During cooking, you can observe the contents of the wok by opening the top cover of the observation tube, and you can also add seasonings through the observation port on the top of the observation tube.

[0038] After cooking, the lid and pot body need to be unlocked. Rotate the handle clockwise to make the locking plate rotate clockwise. The slide rod in the arc groove on the locking plate moves out of the arc groove. The slide rod drives the locking connector to move the corresponding first horizontal part outward. The first horizontal part drives the second horizontal part outward through the vertical part to unlock the lid and pot body.
