[0004] Bidirectional rotation affects stirring efficiency: some existing manual stirrers rotate the stirrer during pressing and releasing, that is:

[0005] When pressing, the gear mechanism drives the stirrer to rotate clockwise;

[0006] When releasing, due to the spring return effect, the gear mechanism drives the stirrer to rotate counterclockwise.

[0007] This bidirectional rotation method has the following problems:

[0008] Stable unidirectional rotation stirring can form continuous vortex to promote uniform mixing, while bidirectional rotation will constantly change the stirring direction, causing the fluid flow to change repeatedly, affecting the uniformity of stirring.

[0009] During the reset process, the reverse rotation will cancel the previously established rotational inertia, resulting in the need to overcome liquid resistance every time the button is pressed, thereby reducing stirring efficiency and increasing operation fatigue.

[0010] Especially for high-viscosity materials such as egg liquid and cream, bidirectional stirring may cause light substances to float and heavy substances to settle, thereby affecting the stirring effect.

DETAILED DESCRIPTION

[0034] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0035] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0036] like Figures 1-4 As shown, a manually driven stirring device of this utility model includes a receiving body 3, a press-type gear drive mechanism, and a stirrer 12. The receiving body 3 is used to receive liquid or semi-fluid substances that need to be stirred. The receiving body 3 has a stirring chamber with an opening at the top and a cover plate 2 installed to close the stirring chamber and fix the stirring mechanism.

[0037] To facilitate user observation of the stirring state, the container body 3 is made of transparent material and has a scale on its upper end to indicate the volume of the liquid contained. In addition, the container body 3 is also equipped with a handle 5 for easy gripping and control of the stirring device.

[0038] A press-type gear drive mechanism is mounted on the cover plate 2. This mechanism includes a press-drive end 1. The user can drive the gear transmission mechanism by pressing down on the press-drive end 1, thereby rotating the stirrer 12 and achieving the stirring function. The stirrer 12 is mounted on the drive end of the press-type gear drive mechanism and is driven by the gear transmission mechanism, enabling the stirrer 12 to perform circumferential stirring in one direction. This invention adopts a unidirectional stirring mode, meaning the stirrer 12 only rotates when pressed and does not rotate in the opposite direction during the release and reset process, ensuring the stability of the stirring flow field and improving the uniformity of stirring.

[0039] The press-type gear drive mechanism includes a linear drive assembly located at the bottom of the press drive end 1. This assembly, through engagement with a first transmission gear 17, effectively transmits the pressing action to the gear transmission system, thereby rotating the stirrer 12. To achieve the conversion from linear motion to rotational motion, the first transmission gear 17 is coaxially connected to a first conical transmission gear 7, which meshes with a second conical transmission gear 8. This gear meshing changes the direction of motion. The second conical transmission gear 8 is coaxially connected to a second transmission gear 10, which meshes with a third transmission gear 9, ultimately transmitting the motion to the stirrer 12, enabling it to rotate and stir. This multi-stage transmission design of the gear drive mechanism allows the stirrer 12 to achieve a large torque output, ensuring good stirring performance even with high-viscosity liquids.

[0040] In order to ensure the reliable connection of the stirrer 12 and the gear mechanism, the output end of the third transmission gear 9 is provided with a connecting shaft sleeve 11, the stirrer 12 is assembled with the connecting shaft sleeve 11 through the encapsulation process, the connecting section 13 is arranged at the top of the stirrer 12, the combination between the stirrer 12 and the driving mechanism is enhanced, meanwhile, the abrasion or abnormal sound caused by the direct metal contact is avoided, and the service life and the operation stability are improved.

[0041] In addition, a linkage shaft 18 is arranged between the first transmission gear 17 and the first conical transmission tooth 7, the linkage shaft 18 penetrates the sliding groove 16 formed in the cover plate 2, so that in the pressing process, the gears are engaged, in the elastic return process, the linkage shaft 18 rises in the sliding groove 16, the first conical transmission tooth 7 and the second conical transmission tooth 8 are no longer in contact and engagement, and the limiting force is not provided, so that the elastic return of the spring 14 can realize the separation of the engagement position, and the purpose of one-way driving is achieved.

[0042] The linear driving assembly comprises the driving rack 6 and the flat section 4 arranged in parallel with the driving rack 6, the driving rack 6 is engaged with the first transmission gear 17, and the downward movement of the pressing driving end 1 can reliably drive the gear to rotate. Meanwhile, a driving piece 15 is arranged at the bottom of the driving rack 6 and the flat section 4, the bottom of the driving piece 15 is sleeved with the spring 14, and the driving rack 6 and the flat section 4 are reset.

[0043] When the user releases the pressing driving end 1, the elastic force of the spring 14 makes the driving rack 6 return to the initial position, and drives the first transmission gear 17 and the first conical transmission tooth 7 to rise along the linkage shaft 18, and the stirrer 12 is not driven to rotate in the reverse direction, the design can avoid the uneven stirring phenomenon caused by the bidirectional rotation, and ensure the stability and uniformity of the mixing effect.

[0044] The utility model discloses a press type gear driving mechanism realizes one-way rotation stirring, avoids the stirring flow field destruction problem that traditional manual stirring device brings in the pressing and releasing process, and reduces unnecessary energy loss simultaneously.

[0045] Since the spring 14 does not drive the stirrer 12 to rotate in the reset process, the stability of the stirring flow field can be ensured, the liquid is uniformly distributed in the stirring process, and the utility model is especially suitable for seasonings, egg liquid, cream and other foods that need to be fully stirred.

[0046] In addition, the device has the advantages of compact structure and simple operation, the user can complete the stirring by pressing only, the operation strength is reduced, the convenience in use is improved, the overall manufacturing and assembly cost is low due to the modular design, and the device is suitable for large-scale production and popularization and application.

[0047] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any change or replacement not through creative labor should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be limited by the protection scope defined in the claims.
