Description

Technical Field

[0001] This utility model belongs to the technical field of food mixers, and in particular relates to a manual kitchen mixer. Background Technology

[0002] In daily life, many ingredients (such as minced garlic, mashed carrots, minced ginger, chopped chili peppers, and chopped nuts) need to be crushed or blended before they can be used in food preparation. For example, Chinese patent application number 202120694091.9 discloses a novel garlic mincer, which includes an upper shell, a middle shell, a lower shell, a gear drive structure, a blade assembly, and garlic mincing blades. The gear drive structure consists of gears, a handle, a pull rope, and a spring. The user pulls the handle to rotate the spring, and when the handle is released, the elastic potential energy of the spring causes the handle to return to its original position, thereby enabling the blades to rotate back and forth to cut food.

[0003] However, this device has certain drawbacks in practical use: when the food pieces are large or hard, the blade may get stuck due to the resistance of the food during the handle reset process, preventing the handle from resetting smoothly and affecting the usability. Therefore, it is necessary to optimize the device to solve the blade jamming problem and improve its applicability. Utility Model Content

[0004] To address the shortcomings of existing technologies, a manual kitchen mixer is provided that avoids blade jamming.

[0005] This utility model is achieved by the following technical solution: a manual kitchen mixer, comprising:

[0006] The cup body has a cavity for holding food;

[0007] Blades, which are located within the cavity and used to stir food;

[0008] A one-way transmission assembly is disposed inside the upper or lower cover of the cup body. The one-way transmission assembly includes a ratchet disc and a pawl disc. One side of the ratchet disc has an axially open groove, and a ratchet wheel is provided on the circumferential inner wall of the groove. The pawl disc is rotatably connected in the groove. The pawl disc includes a disc body and a pawl rotatably connected to the end of the disc body. The other side of the ratchet disc is connected to the blade and can drive the blade to rotate.

[0009] A manual drive assembly, located outside the cup body, is connected to the ratchet disc body via a transmission assembly; and

[0010] An elastic reset component, which works in conjunction with a manual drive component to reset the manual drive component;

[0011] When the manual drive component actively applies force, the pawl and ratchet engage and rotate synchronously. When the manual drive component is passively reset, the pawl and ratchet separate, and the pawl disc spins freely.

[0012] In use, the user first opens the lid of the cup, places the food to be processed into the cup's cavity, and then closes the lid. Next, the user operates the manual drive component, causing the ratchet disc to rotate. The ratchet engages with the ratchet wheel, rotating synchronously. The ratchet disc drives the blade to rotate, cutting and mixing the food. Afterward, when the user releases the manual drive component, the elastic reset component returns it to its original position. At this point, the ratchet and ratchet disengage, the ratchet disc spins freely, and the blade does not rotate. Therefore, there is no force transmission between the manual drive component and the blade, allowing the manual drive component to smoothly reset and enabling the user to apply force again.

[0013] The manually driven components can be pull ropes, buttons, handles, etc.

[0014] The elastic reset component can be a leaf spring, spring, coil spring, spiral spring, etc.

[0015] Preferably, the pawl is located between the disc body and the bottom of the rotating groove. One end of the pawl is provided with a convex shaft that is rotatably connected to the disc body, and the other end of the pawl extends to the outside of the disc body and is provided with an axially extending abutment portion. The abutment portion is used to abut against the circumferential outer wall of the disc body to limit the rotatable angle of the pawl.

[0016] The pawl has a stop portion to limit the angle of rotation of the pawl, preventing the pawl from rotating completely under the disc and thus preventing it from engaging with the ratchet.

[0017] Preferably, the disc is rhomboid in shape and includes two first vertices with acute angles and two second vertices with obtuse angles, and the pawl is rotatably connected to the first vertices.

[0018] The pawl rotates to engage with the ratchet. The disc is rhomboid in shape, with the pawl's rotation positioned at the first apex, facilitating contact between the pawl's abutment and the disc's circumferential sidewall. If the disc is circular, it's difficult to provide sufficient space for the pawl to rotate; if the disc is rectangular, excessive rotation space could make it difficult for the pawl to engage with the ratchet after rotation.

[0019] Preferably, the transmission component between the ratchet disc and the manual drive assembly is a gear assembly, which includes a rack and at least one gear. The manual drive assembly includes a handle, which is connected to the rack and can drive the rack to perform linear reciprocating motion. The gear meshes with the rack and is fixed to the disc body.

[0020] The gear transmission method is more stable. When the user pulls the handle and uses the elastic reset component, the handle drives the rack to make linear reciprocating motion. The rack drives the gear to rotate, and the gear drives the pawl disc to rotate, thus realizing the transmission.

[0021] Preferably, the gear includes a driving pinion, at least one driven large gear, and a force-bearing pinion. The driving pinion meshes with a rack, the driving pinion and the driven large gear are coaxially arranged and fixedly connected, the driven large gear meshes with the force-bearing pinion, and the force-bearing pinion is fixed to the disc body.

[0022] With the above settings, the rotational speed of the pinion is amplified by the transmission ratio between the gears, and the ratchet disc can achieve a faster rotational speed even with a shorter rack stroke.

[0023] Preferably, the upper or lower cover is provided with a linear slide rail, and the rack is slidably fitted on the slide rail.

[0024] By setting a slide rail, it is ensured that the rack will not deviate when sliding.

[0025] Preferably, the blade has multiple layers and is fixed on a rotating shaft. The two ends of the rotating shaft are respectively provided with a rotating hole and a linkage hole. The upper or lower cover of the cup body is provided with a rotating protrusion that mates with the rotating hole. One side of the ratchet disc is provided with a linkage protrusion that extends into the cavity of the cup body and mates with the linkage hole.

[0026] The two ends of the rotating shaft are respectively engaged with the rotating protrusion and the linkage protrusion, which makes it easy to disassemble the blades for cleaning. The blades are multi-layered, resulting in better stirring effect.

[0027] Preferably, the outer side of the cup body is provided with a U-shaped handle, the pull handle is located inside the handle, one end of the pull handle is rotatably connected to the end of the rack, the other end of the pull handle is rotatably connected to the handle, and the elastic reset component is a leaf spring, the two ends of the leaf spring abutting against the pull handle and the handle respectively.

[0028] The handle makes it easy for users to grip, and after gripping the handle, the fingers can apply force to the handle to rotate and pull the rack.

[0029] Preferably, the one-way transmission component is located on the lower cover of the cup body, the upper cover of the cup body is hinged to the cup body and the upper cover is flipped outward by a torsion spring, and a locking mechanism is provided between the cup body or handle and the upper cover to lock the upper cover and the cup body.

[0030] After the user opens the top cover, the top cover will pop up and flip directly, making operation convenient; the locking mechanism mentioned above can be a snap lock, a self-locking switch, magnetic attraction, etc.

[0031] Compared with the prior art, this utility model, through the cooperation of the ratchet disc and the pawl disc, ensures that the blade does not rotate when the manual drive component is reset, thus effectively avoiding the problem of food getting stuck on the blade and preventing the manual drive component from resetting smoothly.

[0046] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0047] like Figure 1 and Figure 2 As shown in the figure, this embodiment 1 discloses a manual kitchen mixer, including a cup body 1. The cup body 1 is hollow to form a cavity for placing food. The cup body 1 includes an upper cover 2 and a lower cover 3, with the lower cover 3 integrally formed with the cup body 1. The upper cover 2 is detachably fixed to the cup body 1. A blade 6 is provided inside the cavity of the cup body 1. The blade 6 has three layers and is fixed on a rotating shaft 61. The upper end of the rotating shaft 61 has a linkage hole 62 with a hexagonal cross-section, and the lower end of the rotating shaft 61 has a rotating hole 63 with a circular cross-section. The bottom wall of the lower cover 3 has a cylindrical rotating protrusion (not shown in the figure) that engages with and rotates in conjunction with the rotating hole 63. The rotation of the rotating shaft 61 drives the rotation of the blade 6 to achieve the purpose of stirring and cutting food.

[0048] like Figure 2 As shown, a handle 4 is provided on the outer side of the cup body 1. The upper end of the handle 4 is fixed to the upper cover 2, while the lower end of the handle 4 is not fixed to any component. A pull handle 5 is provided on the inner side of the handle 4, and a hook 41 is provided on the inner side of the handle 4. The end of the pull handle 5 has a groove that engages with the hook 41, allowing the pull handle 5 to rotate. A leaf spring 51 is provided between the pull handle 5 and the handle 4. The leaf spring 51 applies a spring force to the pull handle 5 to achieve the return of the pull handle 5.

[0049] like Figure 2 , Figure 3 and Figure 7 As shown, the upper cover 2 has a cavity, and a gear assembly and a one-way transmission assembly 8 are installed inside the cavity. The gear assembly includes a rack 74 and a driving pinion 71. Figure 3(Not shown in the diagram) A first driven large gear 72 (driven large gear) and a force-receiving small gear 73. A driving small gear 71 meshes with a rack 74. The driving small gear 71 and the first driven large gear 72 are coaxially arranged and fixedly connected. The first driven large gear 72 meshes with the force-receiving small gear 73, which is fixed to the one-way transmission assembly 8. One end of the rack 74 extends to the outside of the upper cover 2 and is rotatably connected to one end of the handle 5. The user can press the handle 5 to make the rack 74 perform linear reciprocating motion. A slide rail 741 is provided at the bottom of the cavity of the upper cover 2, and the lower end of the rack 74 slides in engagement with the slide rail 741. The number of teeth of the first driven large gear 72 is greater than the number of teeth of the driving small gear 71 and the force-receiving small gear 73, so the force-receiving small gear 73 can achieve a higher rotational speed.

[0050] like Figure 3 , Figures 9 to 11 As shown, the one-way transmission assembly 8 includes a ratchet disc 81 and a pawl disc 82, with the ratchet disc 81 and pawl disc 82 being adapted to each other. The lower side of the ratchet disc 81 has a linkage protrusion 83 that mates with the linkage hole 62, extending into the cavity of the cup body 1. The upper side of the ratchet disc 81 has an axially upward-opening groove 84, with a ratchet wheel 811 arranged on its circumferential inner wall. The pawl disc 82 is rotatably connected within the groove 84. The pawl disc 82 includes a disc body 821 and a pawl 822 located at the end of the disc body 821. A force-bearing pinion 73 is fixed on the disc body 821. A pawl 822 is located between the bottom of the disc body 821 and the rotating groove 84. The pawl 822 is rotatably connected to the disc body 821 via a convex shaft 823. One end of the pawl 822 away from the convex shaft 823 extends to the outside of the disc body 821 and has an axially upward extending abutment portion 824. The abutment portion 824 is used to abut against the circumferential outer wall of the disc body 821 to limit the rotation angle of the pawl 822. The disc body 821 is rhomboid and includes two acute first apex angles 8211 and two obtuse second apex angles 8212. The pawl 822 is rotatably connected to the first apex angles 8211.

[0051] like Figure 10 and Figure 11 As shown, when the handle 5 is pressed, the rack 74 moves outward. At this time, the pinion 73 drives the pawl disc 82 to rotate counterclockwise (forward). The pawl 822 will engage the ratchet 811, thereby achieving synchronous rotation of the pawl disc 82 and the ratchet disc 81, causing the blade 6 to rotate.

[0052] After the handle 5 is released, the leaf spring applies a spring force to the handle 5, causing the rack 74 to move inward. At this time, when the pinion 73 drives the pawl disc 82 to rotate clockwise (in the opposite direction), the pawl 822 will separate from the ratchet 811. At this time, the pawl disc 82 will rotate freely, and the blade 6 will not rotate.

[0053] Example 2

[0054] like Figure 4 and Figure 8 As shown, the difference between this embodiment 2 and embodiment 1 is that the rack 74 of the gear assembly in this embodiment 2 is located on the upper side, and the top of the upper cover 2 is provided with a downwardly extending L-shaped component, which forms a slide rail 741, and the rack 74 is slidably fitted on the slide rail 741.

[0055] Example 3

[0056] like Figure 5 As shown, the difference between Embodiment 3 and Embodiment 2 is that the gear assembly in Embodiment 3 has two driven large gears, namely a first driven large gear 72 and a second driven large gear 721. The second driven large gear 721 meshes with the first driven large gear 72, and the number of teeth of the second driven large gear 721 is greater than that of the first driven large gear 72. The second driven large gear 721 meshes with the force-bearing small gear 73, further increasing the transmission ratio.

[0057] Example 4

[0058] like Figure 6 As shown, the difference between Embodiment 4 and Embodiment 1 is that the gear assembly in Embodiment 4 has two driven large gears, namely a first driven large gear 72 and a second driven large gear 721. The second driven large gear 721 meshes with the first driven large gear 72, and the number of teeth of the second driven large gear 721 is greater than that of the first driven large gear 72. The second driven large gear 721 meshes with the force-bearing small gear 73, further increasing the transmission ratio.

[0059] Example 5

[0060] like Figure 12 and Figure 13 As shown, the difference between this embodiment 5 and embodiment 1 is that the upper and lower ends of the handle 4 in this embodiment 5 are fixedly connected to the cup body 1. The lower cover 3 has a cavity, and the gear assembly, ratchet disc 81 and pawl disc 82 are all disposed in the cavity of the lower cover 3.

[0061] The gear assembly, ratchet disc 81 and pawl disc 82 can be combined in various ways, and are the same as the combinations of gear assembly, ratchet disc 81 and pawl disc 82 in Embodiments 1, 2, 3 and 4, respectively, and will not be described again here.

[0062] The top cover 2 has a hinge ear 22 at its edge, which is hinged to the cup body 1 and can be flipped outward by a torsion spring 23. The other end of the top cover 2 opposite to the hinge ear 22 has a buckle 21, and the handle 4 has a button 42 corresponding to the buckle 21. The button 42 has a mating groove that engages with the buckle 21 to lock the top cover 2 and the cup body 1. By pressing the button 42, the buckle 21 can be disengaged from the mating groove of the button 42 to unlock the top cover 2 and the cup body 1.
