Description

TECHNICAL FIELD

[0001] The utility model belongs to domestic stirring device technical field, especially, relate to a manual food stirring cup. BACKGROUND

[0002] In daily life, many food materials (such as garlic paste, egg liquid, meat paste, etc.) need to be processed by smashing, stirring, etc. before being used for cooking.

[0003] In view of this demand, the Chinese patent with application number 202421186134.2 discloses a manual egg stirring cup, the structure of which includes a cup body, a handle, a blade and a gear assembly. The handle is manually operated to drive the rack, which in turn drives the gear to rotate, and then the blade rotates to realize the stirring function.

[0004] However, the design of the egg stirring cup is mainly aimed at the stirring of liquid food (such as eggs, butter, etc.), which has obvious limitations in actual use. When used to stir solid or high-viscosity food materials such as meat and garlic, the spring sheet provided on the handle is not strong enough to provide sufficient restoring force, which can cause the gear to be stuck with the blade during the reverse rotation process, resulting in the gear being unable to reset smoothly and affecting the user's use. UTILITY MODEL CONTENTS

[0005] To solve the problems in the prior art, a manual food stirring cup is provided, which can avoid the blade from being stuck during the reset rotation.

[0006] The utility model adopts the following technical solutions to achieve the above purposes: a manual food stirring cup, comprising:

[0007] A cup body is provided with a chamber for placing food;

[0008] A blade is arranged in the chamber and used for stirring food;

[0009] A one-way transmission assembly is arranged in the upper cover or the lower cover of the cup body, the one-way transmission assembly is connected with the blade and can drive the blade to rotate only in the forward direction; and

[0010] A manual driving assembly is arranged outside the cup body, the manual driving assembly is connected with the one-way transmission assembly and applies a driving force to the one-way transmission assembly to realize the rotation of the one-way transmission assembly; and

[0011] An elastic reset assembly cooperates with the manual driving assembly and realizes the reset of the manual driving assembly.

[0012] In use, the user first opens the upper cover of the cup body, puts the food to be processed into the chamber of the cup body, and then covers the upper cover. Then, the manual driving assembly is operated to drive the one-way transmission assembly to rotate in the positive direction, thereby driving the blade to rotate in the positive direction synchronously to realize the cutting and stirring of the food. When the user releases the manual driving assembly, the elastic reset assembly automatically resets the manual driving assembly for the next operation. In this process, the reverse movement of the manual driving assembly drives part of the components in the one-way transmission assembly to move in the reverse direction, but due to the design characteristics of the one-way transmission assembly, the blade and the one-way transmission assembly are in a disconnected state when moving in the reverse direction, and there is no force transmission between them. Therefore, the blade will not rotate with the reset of the manual driving assembly, thereby effectively avoiding the problem that the solid food gets stuck in the blade, causing the manual driving assembly to fail to reset smoothly.

[0025] As a preferred, the gear comprises a driving pinion, at least one driven gear and a force pinion, the driving pinion is engaged with the rack, the driving pinion is coaxially arranged with the driven gear and fixedly connected with the driven gear, the driven gear is engaged with the force pinion, and the force pinion is fixed with the disc body.

[0026] Through the above arrangement, the transmission ratio between the gears is used to amplify the rotation speed of the force pinion, and the rack has a short stroke, so that the pawl disc has a faster rotation speed.

Detailed Implementation

[0050] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0051] like Figure 1 and Figure 2 As shown in the figure, this embodiment 1 discloses a manual food mixing cup, 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 in 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 is inserted into and rotates with the rotating hole 63. The rotation of the rotating shaft 61 can drive the rotation of the blade 6 to achieve the purpose of mixing and cutting food.

[0052] 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.

[0053] 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 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 a 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.

[0054] like Figure 3 , Figure 9 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 rotatable angle of the pawl 822.

[0055] 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.

[0056] 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.

[0057] Example 2

[0058] 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.

[0059] Example 3

[0060] 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.

[0061] Example 4

[0062] 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.

[0063] Example 5

[0064] like Figure 12 and Figure 13As shown, the difference between Embodiment 5 and Embodiment 1 is that the handle 4 in Embodiment 5 is fixedly connected to the cup body 1 at both ends. The lower cover 3 has a cavity, and the gear assembly, ratchet disc 81, and pawl disc 82 are all disposed within the cavity of the lower cover 3. The arrangement of the gear assembly, ratchet disc 81, and pawl disc 82 can vary and is the same as that in Embodiments 1, 2, 3, and 4, and will not be described further here. The upper cover 2 has a hinge lug 22 at its edge, which is hinged to the cup body 1 and allows the upper cover 2 to be flipped outwards via a torsion spring 23.

[0065] The top cover 2 has a buckle 21 at the other end relative to the hinge ear 22. The handle 4 has a button 42 at the position 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.
