[0055] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0056] like Figures 1-7 As shown, one embodiment of the present invention provides a food processor, including a housing 1, a first transmission assembly, a second transmission assembly, a fixed arm 2, a movable arm 3, a second connecting shaft 5, and a screw 7;

[0057] The housing 1 has a communicating receiving cavity and an opening 101. One end of the movable arm 3 is rotatably connected to the receiving cavity through the first connecting shaft 4, and the other end of the movable arm 3 passes through the opening 101.

[0058] A fixing arm 2 is provided at one end of the opening 101, and the fixing arm 2 is fixed on the housing 1;

[0059] The movable arm 3 is connected to the screw 7 via the first transmission assembly, so as to drive the screw 7 to rotate around its axis;

[0060] The screw 7 is connected to the second connecting shaft 5 via the second transmission assembly to drive the second connecting shaft 5 to rotate around its axis. The stirring component 6 is connected to the second connecting shaft 5.

[0061] With the palm placed on the fixed arm 2 and the fingers gripping the movable arm 3, the movable arm 3 rotates around the axis of the first connecting shaft 4. The end of the movable arm 3 away from the first connecting shaft 4 moves towards the fixed arm 2. The movable arm 3 transmits power to the screw 7 through the first transmission assembly, causing the screw 7 to rotate around its axis. The screw 7 transmits power to the second connecting shaft 5 through the second transmission assembly, causing the second connecting shaft 5 to rotate around its own axis. This allows the stirring component 6 to stir the material to be stirred. The user can operate it with one hand, providing the convenience of single-handed operation.

[0062] The fixed arm 2 and the movable arm 3 are arranged opposite each other in a V-shape. The further away the user's grip on the movable arm 3 is from the first connecting shaft 4, the less effort is required. Therefore, within a reasonable range, the longer the fixed arm 2 and the movable arm 3 are, the less effort is required to stir the material. The opening 101 has a large diameter, which does not affect the movement of the movable arm 3.

[0063] When the axis of the second connecting shaft 5 is perpendicular to the horizontal plane, the axis of the first connecting shaft 4 is parallel to the horizontal plane. The movable arm 3 rotates around the axis of the first connecting shaft 4. The end of the movable arm 3 away from the first connecting shaft 4 moves closer to or further away from the fixed arm 2, which is a vertical rotation.

[0064] Preferred, such as Figure 6 As shown, the second connecting shaft 5 includes a first shaft and a second shaft that are detachably connected. The first shaft is connected to the second gear 17, and the second shaft is connected to the stirring components 6. Multiple stirring components 6 are provided and are evenly arranged around the axis of the second connecting shaft 5. Because the second shaft and the first shaft are detachable, it is convenient to replace the stirring components 6.

[0065] Furthermore, the stirring component 6 can be a stirring rod or a crushing blade. People can replace the connected second shaft and stirring component 6 as needed to achieve functions such as stirring and crushing. The work to be processed can be a liquid, a solid, or a solid-liquid mixture. It can evenly stir the work to be stirred or other liquids, and can also crush ginger and garlic, making it more practical.

[0066] According to one embodiment of the present invention, the receiving cavity includes a first chamber 102, a second chamber 103 and a third chamber 104 that are connected in sequence.

[0067] The first connecting shaft 4 is disposed within the first chamber 102;

[0068] The axis of screw 7 is parallel to the axis of the second connecting shaft 5;

[0069] The axis of the first connecting shaft 4 is perpendicular to the axis of the second connecting shaft 5;

[0070] The first transmission assembly includes a transmission component, a first connecting member, and a threaded cylinder 10;

[0071] The movable arm 3 drives the first connecting piece to move along the axis of the screw 7 via the transmission component;

[0072] The first connecting piece is fixedly connected to the threaded cylinder 10;

[0073] The threaded cylinder 10 is screwed onto the screw rod 7;

[0074] The end of the screw 7 near the second connecting shaft 5 is rotatably connected to the third chamber 104 via the first bearing.

[0075] According to one embodiment of the present invention, the first transmission assembly further includes a first ring plate 11, a second ring plate 12, and a spring 13;

[0076] Spring 13 is sleeved on the outer wall of threaded cylinder 10. One end of spring 13 is connected to the first ring plate 11, and the other end is connected to the second ring plate 12.

[0077] The outer side wall of the first ring plate 11 is connected to the side wall of the second chamber 103, and the inner side wall of the second ring plate 12 is connected to the threaded cylinder 10.

[0078] Furthermore, the housing 1 includes a first outer shell, an annular shell, and a second outer shell connected to each other. The first outer shell has a first chamber 102, the annular shell has a second chamber 103, and the second outer shell has a third chamber 104. The first chamber 102, the second chamber 103, and the third chamber 104 are connected to form a receiving cavity.

[0079] It should be noted that by designing the housing 1 according to the specific structure of the first transmission component and the second transmission component, material costs can be saved.

[0080] The movable arm 3 is gripped and brought close to the fixed arm 2. The movable arm 3 rotates around the axis of the first connecting shaft 4, driving the first connecting member to move away from the stirring component 6 along the axis of the screw 7 via a transmission component. This causes the threaded cylinder 10, fixedly connected to the first connecting member, to move along the axis of the screw 7. The threaded cylinder 10 is screwed to the screw 7, thus driving the screw 7 to rotate around its own axis. The screw 7, through the second transmission component, drives the second connecting shaft 5 to rotate around its axis, thereby driving the stirring component 6 to stir. During the movement of the threaded cylinder 10, one end of the spring 13 is connected to the second ring plate 12, which is connected to the threaded cylinder 10. The other end of the spring 13 is connected to the first ring plate 11. The first ring plate 11 remains stationary, while the second ring plate 12 moves closer to the first ring plate 11 under the influence of the threaded cylinder 10. Therefore, the spring 13 is in a compressed state.

[0081] When you release your hand, the spring 13 releases its elastic potential energy, causing the second ring plate 12 to move closer to the stirring component 6, and the threaded cylinder 10 to move in the opposite direction, causing the screw 7 to reverse.

[0082] There are at least two types of transmission components:

[0083] The first type of transmission component: such as Figures 1-6 As shown, the transmission components include a first gear 8 and a gear plate 9;

[0084] The first gear 8 and the movable arm 3 are both fixedly connected to the first connecting shaft 4. The first connecting shaft 4 is rotatably connected in the receiving cavity. The first gear 8 and the toothed plate 9 mesh with each other. One end of the toothed plate 9 is fixedly connected to the threaded cylinder 10 through the first connecting piece.

[0085] At this time, the movable arm 3 drives the first gear 8 to rotate around the axis of the first connecting shaft 4. The first gear 8 drives the toothed plate 9 that meshes with it to move up and down. The toothed plate 9 drives the threaded cylinder 10 to move up and down through the first connecting piece, thereby causing the screw 7 to rotate around its own axis.

[0086] The second type of transmission component, such as Figure 7 As shown, the transmission components include a rotating roller 29 and a connecting belt 30;

[0087] Both the rotating roller 29 and the movable arm 3 are fixedly connected to the first connecting shaft 4, which is rotatably connected inside the receiving cavity.

[0088] One end of the connecting belt 30 is connected to the side wall of the rotating roller 29, and the other end is connected to the threaded cylinder 10 through the first connector.

[0089] At this time, the movable arm 3 drives the rotating roller 29 to rotate around the axis of the first connecting shaft 4, and then pulls the first connecting piece along the axis of the screw 7 through the connecting belt 30, so that the threaded cylinder 10 moves synchronously, and drives the screw 7 screwed to the threaded cylinder 10 to rotate along its own axis.

[0090] Of course, in this embodiment, the spring 13 can also be set in other positions. For example, one end of the spring 13 is connected to the inner wall of the first chamber 102, and the other end is connected to the end of the toothed plate 9 away from the threaded cylinder 10. The length direction of the spring 13 is the same as the length direction of the toothed plate 9. A telescopic rod is provided inside the spring 13. The telescopic rod is a freely telescopic rod body used to limit the extension and retraction direction of the spring 13. It can also play the role of resetting the movable arm 3. Its purpose has not deviated from the design concept of this utility model. Therefore, it should fall within the protection scope of this utility model.

[0091] Preferably, the two ends of the first connecting shaft 4 are rotatably connected to the two opposite side walls of the receiving cavity via a fourth bearing.

[0092] Optionally, circular grooves are provided on the opposite side walls of the receiving cavity, and the two ends of the first connecting shaft 4 are respectively located in a circular groove and rotatably connected to the circular groove.

[0093] Of course, in this embodiment, the movable arm 3 can also be rotatably connected to the first connecting shaft 4, and the first connecting shaft 4 is fixedly connected to the receiving cavity. At this time, the first gear 8 or the rotating roller 29 is fixedly connected to the movable arm 3, and the first gear 8 or the rotating roller 29 is rotatably connected to the first connecting shaft 4.

[0094] According to one embodiment of the present invention, the first transmission assembly further includes a limiting member, which is used to guide the threaded cylinder 10 to move along the axial direction of the screw 7;

[0095] The limiting component includes a slider 14 fixedly connected to the outer wall of the second ring plate 12, and a strip plate 15 fixedly connected to the inner wall of the second chamber 103. A strip groove is provided on the strip plate 15, and the slider 14 is slidably connected in the strip groove.

[0096] The setting of the limiting component ensures that the toothed plate 9, which is connected to the threaded cylinder 10 through the first connecting component, can always maintain engagement with the first gear 8, thereby improving the stability of operation.

[0097] Furthermore, multiple sliders 14 and strip plates 15 are provided, with multiple sliders 14 evenly arranged around the axis of the threaded cylinder 10, and each slider 14 and strip plate 15 corresponding to the other.

[0098] Of course, in this embodiment, the limiting member can also take other forms. For example, the limiting member includes a strip-shaped block connected to the inner wall of the second chamber 103, and a groove adapted to the strip-shaped block is provided on the second ring plate 12, so that the second ring plate 12 can slide along the length direction of the strip-shaped block, and the length direction of the strip-shaped block is the same as the axial direction of the threaded cylinder 10. Its purpose does not depart from the design concept of this utility model, therefore, it should fall within the protection scope of this utility model.

[0099] Of course, in this embodiment, the first transmission assembly can also take other forms. For example, the first transmission assembly includes a sliding groove formed on the side wall of the movable arm 3, and also includes an internal threaded ring and a connecting rod. The connecting rod is slidably connected in the sliding groove, and one end of the connecting rod is connected to the top of the internal threaded ring. When the movable arm 3 rotates around the axis of the first connecting shaft 4, the end of the movable arm 3 away from the first connecting shaft 4 approaches the fixed arm 2, that is, one end tilts upward. At this time, the connecting rod slides in the sliding groove and moves upward under the drive of the movable arm 3, thereby driving the internal threaded ring to move upward. At this time, the screw 7 screwed to the internal threaded ring rotates around its own axis. The internal threaded ring is slidably connected in the second chamber 103 by a limiting member.

[0100] According to one embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the second transmission assembly is disposed within the third chamber 104;

[0101] The second transmission assembly includes a second connector 27, an internal gear ring 16, a gear set, and a second gear 17.

[0102] The internal gear ring 16 is connected to the screw 7 via the second connector 27. The axis of the internal gear ring 16 coincides with the axis of the screw 7. The internal gear ring 16 is connected to the second gear 17 via a gear set.

[0103] The third chamber 104 has a circular hole on the side away from the second chamber 103. One end of the second connecting shaft 5 is connected to the second gear 17, and the other end passes through the circular hole and is connected to the stirring component 6. The second connecting shaft 5 and the circular hole are rotatably connected by the second bearing.

[0104] The second bearing allows the second connecting shaft 5 to rotate more smoothly, and the second connecting shaft 5 cannot move along its own axis.

[0105] According to one embodiment of the present invention, the gear set includes a first rotating shaft 18 and a second rotating shaft 19;

[0106] The first rotating shaft 18 is connected to the third gear 20 and the fourth gear 21, and the second rotating shaft 19 is connected to the fifth gear 22 and the sixth gear 23.

[0107] The internal gear ring 16 meshes with the third gear 20, and the fourth gear 21 meshes with the fifth gear 22;

[0108] The first rotating shaft 18 is rotatably connected to the third chamber 104, and a sliding groove 24 is provided in the third chamber 104. The second rotating shaft 19 is movably connected to the sliding groove 24.

[0109] It should be noted that the fourth gear 21 and the fifth gear 22 are always in a meshing state.

[0110] Preferably, the length of the slide groove 24 is greater than the diameter of the second rotating shaft 19. When the threaded cylinder 10 moves in the first direction, the sixth gear 23 and the second gear 17 mesh; when the threaded cylinder 10 moves in the second direction, the sixth gear 23 and the second gear 17 separate and do not contact. At this time, the screw 7 is connected to the second connecting shaft 5 through the second transmission assembly to drive the screw 7 to rotate unidirectionally around its axis.

[0111] Optionally, the length of the slide groove 24 is equal to the diameter of the second rotating shaft 19, and the sixth gear 23 and the second gear 17 are always in a meshing state. At this time, the screw 7 is connected to the second connecting shaft 5 through the second transmission assembly to drive the screw 7 to rotate bidirectionally around its axis.

[0112] The second connector 27 includes a connecting plate and two connecting posts. The two connecting posts are symmetrically connected to both ends of the connecting plate. The connecting plate is connected to the screw 7, and both connecting posts are connected to the internal gear ring 16.

[0113] Of course, in this embodiment, the second connecting member 27 can also be a concave plate, which does not deviate from the design concept of this utility model. Therefore, it should fall within the protection scope of this utility model.

[0114] The working principle of the second transmission component: When the threaded cylinder 10 moves along the first direction and drives the screw 7 to rotate, the end of the movable arm 3 away from the first connecting shaft 4 approaches the fixed arm 2. The screw 7 drives the internal gear ring 16 to rotate through the second connecting piece 27, and then the internal gear ring 16 drives the third gear 20 to rotate, so that the fourth gear 21 rotates synchronously. Under the dual action of the fourth gear 21 and the slide groove 24, the fifth gear 22 rotates around its own axis and moves along the slide groove 24 toward the second gear 17 until the sixth gear 23 meshes with the second gear 17, transmitting power to the second gear 17, so that it drives the second connecting shaft 5 to rotate around its own axis. The axis of the second gear 17 coincides with the axis of the second connecting shaft 5.

[0115] When the threaded cylinder 10 moves in the second direction, causing the screw 7 to rotate, one end of the movable arm 3 moves away from the fixed arm 2. The screw 7 drives the internal gear ring 16 to rotate in the opposite direction through the second connecting piece 27. In turn, the internal gear ring 16 drives the third gear 20 to rotate in the opposite direction, causing the fourth gear 21 to rotate synchronously in the opposite direction. Under the combined action of the fourth gear 21 and the slide groove 24, the fifth gear 22 rotates while moving away from the second gear 17 along the slide groove 24 until the sixth gear 23 separates from the second gear 17. This allows for multiple applications of force to the second gear 17, causing the second connecting shaft 5 to rotate at high speed, resulting in higher stirring efficiency and better effect.

[0116] Of course, in this embodiment, multiple gear sets can be provided, as long as the internal gear ring 16 can rotate, driving the second gear 17 to rotate around the axis of the second gear 17. The purpose has not deviated from the design concept of this utility model, and therefore, it should fall within the protection scope of this utility model.

[0117] The first rotating shaft 18, the third gear 20 and the fourth gear 21 are coaxially arranged, and the second rotating shaft 19, the fifth gear 22 and the sixth gear 23 are coaxially arranged.

[0118] Furthermore, a second circular plate 28 is also provided in the third chamber 104. The second circular plate 28 is connected to the inner wall of the third chamber 104 through an arc-shaped block. The space between the second circular plate 28 and the third chamber 104 is called the installation area. The second gear 17, the third gear 20, the fourth gear 21, the fifth gear 22 and the sixth gear 23 are all located in the installation area. The second circular plate 28 and the third chamber 104 are respectively provided with a first circular groove on the side that is close to each other. The two ends of the first rotating shaft 18 are respectively rotatably connected in the first circular groove through a third bearing.

[0119] The second circular plate 28 is also provided with a sliding groove 24, and the two ends of the second rotating shaft 19 are respectively rotatably connected in the two sliding grooves 24.

[0120] Among them, the diameter of the third gear 20 is smaller than the diameter of the fourth gear 21, the diameter of the fifth gear 22 is smaller than the diameter of the sixth gear 23, and the sixth gear 23 and the third gear 20 do not contact each other and will not interfere.

[0121] According to one embodiment of the present invention, the movable arm 3 includes a first rod 301 and two second rods 302, the two second rods 302 being fixedly connected to both sides of the first rod 301, and the length of the first rod 301 being less than the length of the second rods 302.

[0122] When the first type of transmission component is used, the two second rods 302 are respectively connected to the two ends of the first gear 8;

[0123] When the second type of transmission component is used, the two second rods 302 are respectively connected to the two ends of the rotating roller 29.

[0124] It should be noted that since the first gear 8 or the rotating roller 29 is centrally located between the two second rods 302, the gripping feel of the movable arm 3 is better and the rotation of the movable arm 3 is smoother.

[0125] According to one embodiment of the present invention, the first connecting member includes a first circular plate 25 and a first connecting rod 26;

[0126] One end of the first connecting rod 26 is connected to the first circular plate 25, and the other end is connected to the threaded cylinder 10;

[0127] The diameter of the first circular plate 25 is smaller than the inner diameter of the first ring plate 11.

[0128] When the first type of transmission component is used, the first circular plate 25 is fixedly connected to the toothed plate 9;

[0129] When the second type of transmission component is used, the first circular plate 25 is fixedly connected to the connecting belt 30.

[0130] Furthermore, multiple first connecting rods 26 are provided and are evenly distributed around the axis of the first circular plate 25. The multiple first connecting rods 26 can also block the spring 13 and the threaded cylinder 10, preventing the spring 13 from deviating in direction during the extension and retraction process and causing interference to the threaded cylinder 10.

[0131] When the movable arm 3 rotates around the first connecting shaft 4, the first connecting shaft 4 drives the first circular plate 25 to move along the length of the screw 7 through the transmission component, which in turn drives the first connecting rod 26 to move, and then the threaded cylinder 10 to move.

[0132] It should be noted that the axis of the first connecting shaft 4 is perpendicular to the axis of the second connecting shaft 5, and the axis of the screw 7 is in the same direction as the axis of the toothed plate 9. Preferably, the axis of the second connecting shaft 5 coincides with the axis of the screw 7.

[0133] For ease of description, the direction of movement of the threaded cylinder 10 is referred to as the first direction and the second direction. The second direction is opposite to the first direction, and both the first and second directions are consistent with the length direction of the threaded cylinder 10.

[0134] The movable arm 3 is gripped and rotated around the axis of the first connecting shaft 4. At this time, the movable arm 3 is close to the fixed arm 2. The first gear 8 drives the toothed plate 9 to move in the first direction. The toothed plate 9 drives the threaded cylinder 10 to move in the first direction through the first connecting piece. The spring 13 is compressed. Since the slider 14 is slidably connected in the slot of the strip plate 15, the threaded cylinder 10, which is connected to the slider 14 through the second ring plate 12, can only move along the first direction without rotating. The screw 7 is rotatably connected to the side wall of the third chamber 104 through the first bearing. Under the action of the threaded cylinder 10, the screw 7 rotates around its own axis. The second connecting member 27 drives the internal gear ring 16 to rotate, and the internal gear ring 16 drives the third gear 20 to rotate around the axis of the first rotating shaft 18. The fourth gear 21 rotates synchronously. Under the dual action of the fourth gear 21 and the slide groove 24, the fifth gear 22 rotates around its own axis and moves along the length direction of the slide groove 24 at the same time. As a result, the second rotating shaft 19 rotates and slides in the slide groove 24, so that the sixth gear 23 meshes with the second gear 17, driving the second gear 17 to rotate. This causes the second connecting shaft 5 connected to the second gear 17 to rotate, and the stirring member 6 rotates to stir the material to be stirred.

[0135] Release the movable arm 3, and the spring 13 gradually returns to its original position, pushing the threaded cylinder 10 to move in the second direction. The toothed plate 9 moves in the second direction, causing the first gear 8 to rotate in the opposite direction. Consequently, the angle between the movable arm 3 and the fixed arm 2 increases. At the same time, the screw 7 rotates in the opposite direction, causing the internal gear ring 16 to rotate synchronously. The internal gear ring 16 drives the third gear 20 to rotate around the axis of the first rotating shaft 18, and the fourth gear 21 rotates synchronously. While the fourth gear 21 drives the fifth gear 22 to rotate, the fifth gear 22, under the combined action of the fourth gear 21 and the slide groove 24, rotates... 2. The second rotating shaft 19 rotates around its own axis and moves along the length of the slide 24 at the same time. As a result, the second rotating shaft 19 rotates and slides in the slide 24, so that the sixth gear 23 separates from the second gear 17. After no rotational force is applied to the second gear 17, the second connecting shaft 5 rotates. Since the resistance of the material to be stirred may be large, the rotation speed of the stirring component 6 decreases. When the spring 13 returns to its original position (the movable arm 3 is in the initial position) or during the return process, the user can continue to grip it and apply rotational force to the second gear 17 again. This allows the stirring component 6 to be in a relatively high-speed rotation state, which is more time-saving and labor-saving, and the stirring effect is better.
