Specific embodiments

[0023] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0024] Embodiment 1.

[0025] Refer to Figure 1 and Figure 2 As shown, the quick tool change mechanism of the blender described in this embodiment. The blender has a working container 10 for accommodating food materials, including:

[0026] An opening 20 is provided on the working container 10 and is communicated with the working container 10;

[0027] A tool holder 30 is installed on the working container 10 during use and is used to form a sealed fit with the opening 20;

[0028] A stirring and cutting part 40 is rotatably installed on the tool holder 30 and is used to receive an external driving force to rotate;

[0029] A buckling part 50 is rotatably connected to the tool holder 30 and is used to receive an external force to move the tool holder 30 along the assembly direction of the tool holder 30 itself;

[0030] Among them, the tool holder 30 forms a sealed fit or releases the sealed fit with the opening 20 under the action of the buckling part 50; when the tool holder 30 forms a sealed fit with the opening 20, the stirring and cutting part 40 extends into the working container 10 from the opening 20.

[0031] Specifically, a guiding groove 51 is provided on the buckling part 50. The guiding groove 51 is located on the rotation axis of the buckling part 50 (rotating relative to the tool holder 30). An eccentric boss 52 that is eccentrically matched with the guiding groove 51 is provided on the working container 10. The buckling part 50 rotates around the eccentric axis of the eccentric boss 52 under the action of an external force through the cooperation of the guiding groove 51 and the eccentric boss 52 to drive the tool holder 30 to move along the assembly direction of the tool holder 30 itself.

[0032] The following combines the actual use scenario, such as making fruit and vegetable juice, to illustrate the working process of this quick tool change mechanism:

[0033] First, the user holds the tool holder 30, aligns it with the opening 20, and aligns the guiding groove 51 on the fastening and rotating member 50 with the eccentric boss 52 on the working container 10. At this time, there is a certain gap between the tool holder 30 and the opening 20. Subsequently, the user rotates the fastening and rotating member 50 (for example, clockwise). By driving the tool holder 30 with the fastening and rotating member 50, the tool holder 30 rotates around the eccentric axis of the eccentric boss 52. The tool holder 30 gradually moves towards the working container 10 until it closely adheres to the opening 20 and forms a seal, completing the installation of the tool holder 30. Finally, the prepared food ingredients are placed into the working container 10 and the power supply is connected. The blender is started, and the stirring and cutting member 40 rotates at a high speed under the drive of an external driving force to stir, mix, or crush the food ingredients in the working container 10.

[0034] When the production is completed, the power supply is turned off. The user rotates the fastening and rotating member 50 towards the side opposite to the initial rotation direction (for example, counterclockwise), so that the tool holder 30 moves away from the working container and disengages from the sealed cooperation with the opening 20. Then, the tool holder 30 can be easily removed for cleaning, and different specifications of the stirring and cutting member 40 can also be replaced according to needs.

[0035] In some embodiments, as Figure 1 shown, for higher stability and balance, two guiding grooves 51 are oppositely provided on the fastening and rotating member 50. Both of the two guiding grooves 51 are located on the rotation axis of the fastening and rotating member 50, and two corresponding eccentric bosses 52 are provided for the guiding grooves 51. In this way, through the cooperation of the two guiding grooves 51 and the eccentric bosses 52, a dual support is formed, effectively restricting the shaking of the fastening and rotating member 50 during rotation and the problem of unbalanced force, and avoiding the situation that the tool holder 30 is installed obliquely or not in place.

[0036] In some embodiments, as Figure 1 and Figure 2 shown, for easy gripping and rotation, the fastening and rotating member 50 has an arc-shaped structure with both ends converging inward. The fastening and rotating member 50 is rotatably connected to the tool holder 30 by respectively providing rotating shafts 53 on the opposite surfaces at both ends of the arc-shaped structure, and shaft seats 31 for rotatably cooperating with the rotating shafts 53 are provided on the tool holder 30. In this embodiment, the fastening and rotating member 50 is made of plastic material. Its arc-shaped structure with both ends converging inward can generate an inward clamping force on the rotating shafts 53 at both ends, and cooperate more closely with the shaft seats 31 on the tool holder 30, thereby improving the connection stability and durability.

[0037] In some embodiments, as Figure 2As shown, a buckle 54 is provided on the buckle rotating member 50, and a buckle foot 32 cooperating with the buckle 54 is provided on the tool rest 30. In this way, by providing the buckle 54 on the buckle rotating member 50 and the cooperating buckle foot 32 on the tool rest 30, even in the case of external vibration or accidental collision, the cooperation between the buckle 54 and the buckle foot 32 can firmly fix the tool rest 30 on the working container 10 to prevent accidental loosening. At the same time, when the user rotates the buckle rotating member 50 to install the tool rest 30, the buckle 54 and the buckle foot 32 will make a clear "click" sound or a change in hand feeling when in place, providing a clear installation-in-place prompt for the user and avoiding potential safety hazards caused by improper installation.

[0038] In some embodiments, as Figure 1 and Figure 2 shown, for the convenience of cleaning, the stirring and cutting member 40 includes a cutter head portion 41 and a transmission portion 42. The transmission portion 42 is rotatably installed on the tool rest 30, and the cutter head portion 41 is detachably installed on the transmission portion 42. In this way, the separable design also facilitates the user to use different cleaning tools, such as brushes, running water, etc., to clean the cutter head portion 41 comprehensively without leaving any sanitary dead corners. And when the cutter head portion 41 is worn or needs to be replaced, the user can directly replace the cutter head portion 41 without replacing the entire stirring and cutting member 40, which is more economical and practical and also extends the service life of the transmission portion 42.

[0039] In some embodiments, as Figure 1 and Figure 2 shown, a boss structure 33 is provided on the tool rest 30. The circumferential contour of the boss structure 33 is adapted to the contour of the opening 20, and a gasket 60 forming a sealing fit with the opening 20 is sleeved on the boss structure 33. In this way, the design of the boss structure 33 increases the contact area between the tool rest 30 and the opening 20. Cooperating with the gasket 60 with good elasticity, a tight sealing structure can be formed, effectively preventing the leakage of food ingredients liquid from the gap between the tool rest and the opening during the working process and ensuring the safety and hygiene of use.

[0040] In some embodiments, as Figure 1 shown, the opening 20 is provided at the bottom of the working container 10. With this structural design, on the one hand, the food ingredients will naturally move closer to the stirring and cutting member 40 under the action of gravity, forming more effective stirring and cutting. On the other hand, it can shorten the direct connection between the stirring and cutting member 40 and the external driving mechanism, facilitating the power transmission between the two.

[0041] The quick blade changing mechanism of the blender provided in the present embodiment allows the user to easily complete the installation and disassembly of the blade holder by simply rotating the buckle and rotary piece, without the need for complicated operating steps and tools. The eccentric structure design enables the blade holder to quickly move into place during the rotation process, thereby shortening the installation time. The snap connection method can firmly fix the blade holder in a predetermined position, and it will not easily loosen or fall off even under high-speed operation. The precise sealing cooperation between the blade holder and the working container effectively prevents leakage of food, and also facilitates the user to thoroughly clean the blade holder and the working container, thereby effectively improving the user experience.
