The blending mechanism is one of the key components of a food blender, used to blend food. However, in existing blending mechanisms, when the fixed base retracts from the mounting base, the mounting base lacks a locking mechanism to engage the fixed base, requiring the user to continuously press to maintain overlap. Prolonged pressing can easily cause hand fatigue and inconvenience.

[0003] Therefore, it is necessary to provide a stirring mechanism to solve the above-mentioned technical problems. Utility Model Content

[0004] This utility model provides a stirring mechanism that solves the problem that existing stirring mechanisms either do not have a locking structure on the mounting base or have a locking structure on the mounting base, requiring continuous pressing by the user, which is inconvenient to use.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a stirring mechanism, including a mounting base for mounting on a mixer, a fixed base that can extend and retract relative to the mounting base, a stirring device fixed on the mounting base and having one end passing through the fixed base, and a reset component connected to the fixed base and the mounting base respectively for resetting the fixed base. The mounting base is provided with a first limiting component extending into the fixed base, and the fixed base is provided with a second limiting component extending into the first limiting component for engaging with the first limiting component. When the fixed base slides down relative to the mounting base under the action of the reset component to a position relative to the first limiting component, the second limiting component engages with the first limiting component to stop the fixed base and the mounting base from sliding relative to each other.

[0006] In this utility model, the first limiting component includes an elastic plate and a first barb connected to the elastic plate;

[0007] The second limiting component includes a first sleeve located at the center of the fixed seat and having a hollow structure, and a second barb connected to the first sleeve and adapted to engage with the first barb.

[0008] In this utility model, the second limiting component further includes a second sleeve that is sleeved on the first sleeve and can move along the length direction of the first sleeve. The second sleeve is provided with a limiting protrusion that fits with the first barb. The second sleeve is used to separate the first barb from the second barb.

[0009] In this invention, the first barb has a first inclined surface on the side near the second barb, and the second barb has a second inclined surface that matches the first inclined surface.

[0010] In this utility model, a third inclined surface and a fourth inclined surface are respectively provided on both sides of the limiting protrusion. The first barb presses against the third inclined surface to separate the first barb from the second barb. The first barb is attached to the fourth inclined surface to drive the second sleeve to move. When the second sleeve is attached to the second barb, the first barb presses against the fourth inclined surface and the first barb is separated from the fourth inclined surface.

[0011] In this invention, the second sleeve is further provided with a plurality of fixing protrusions extending toward the second barb, and the plurality of fixing protrusions are respectively located on both sides of the second barb.

[0012] In this invention, the reset assembly includes a spring, with both ends of the spring respectively sleeved on the first sleeve and the elastic plate.

[0013] In this invention, the reset assembly includes a first magnetic ring located on the periphery of the elastic plate and a second magnetic ring that is attached to the second barb and has the opposite magnetism to the first magnetic ring.

[0014] In this invention, a protective cover is provided around the fixed base, and the stirring device includes a cutter shaft fixed on the mounting base and a stirring blade connected to the cutter shaft and located inside the protective cover.

[0015] In this utility model, the periphery of the fixing base is also provided with a plurality of through grooves extending along the height direction of the fixing base;

[0016] The mounting base also includes a third sleeve, on which multiple limiting blocks are provided that pass through the through groove.

[0017] Compared with the prior art, the advantages of this utility model are as follows: When the stirring device cannot stir the food outside the fixed seat, it squeezes the mounting seat, and the fixed seat moves towards the mounting seat. When the second limiting component of the fixed seat engages with the first limiting component of the mounting seat, the stirring device exposes the fixed seat part to stir the food, while the reset component squeezes the fixed seat in the opposite direction to prevent the fixed seat from continuing to move towards the mounting seat. When squeezing the food, there is no need to continuously press the mounting seat, which can stir larger food items, making it more convenient for users. Attached Figure Description

[0035] The following is a preferred embodiment of a stirring mechanism provided by this utility model that can solve the above-mentioned technical problems.

[0036] Please refer to Figure 1 , Figure 2 and Figure 3 ,in Figure 1 This is a perspective view of the stirring mechanism of this utility model. Figure 2 This is a top view of the stirring mechanism of this utility model. Figure 3 for Figure 2 Sectional view along section line AA Figure 1 .

[0037] In the diagram, units with similar structures are represented by the same labels.

[0038] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0039] This utility model provides a stirring mechanism, including a mounting base 11 for mounting on a mixer, a fixed base 12 retractable relative to the mounting base 11, a stirring device 13 fixed to the mounting base 11 with one end passing through the fixed base 12, and a reset component connected to the fixed base 12 and the mounting base 11 respectively for resetting the fixed base 12. The mounting base 11 is provided with a first limiting component 111 extending into the fixed base 12, and the fixed base 12 is provided with a second limiting component 122 extending into the first limiting component 111 for engaging with the first limiting component 111. When the fixed base 12 slides down relative to the mounting base 11 to a position relative to the first limiting component 111 under the action of the reset component, the second limiting component 122 engages with the first limiting component 111 to... The fixed base 12 and the mounting base 11 stop sliding relative to each other. The mounting base 11 is used to fix the mixer, and the mixing device 13 is used to connect to the drive source of the mixer. When the mounting base 11 is pressed, the fixed base 12 moves on the mounting base 11, so that the mixing device 13 located in the mounting base 11 is exposed to the mounting base 11 to mix larger ingredients. When the second limiting component 122 of the fixed base 12 and the first limiting component 111 of the mounting base 11 are attached and locked, the second limiting component 122 is locked on the mounting base 11. At the same time, the reset component presses the fixed base 12 in the opposite direction to prevent the fixed base 12 from moving further towards the mounting base 11. When squeezing ingredients, it is not necessary to continuously press the mounting base 11 to mix larger ingredients, which is more convenient for users.

[0040] Please refer to Figure 9 and Figure 10 , Figure 9 This is a perspective view of the mounting base of the stirring mechanism of this utility model. Figure 10 This is a perspective view of the fixed base of the stirring mechanism of this utility model. The first limiting component 111 includes an elastic plate 1111 and a first barb 1112 connected to the elastic plate 1111. The second limiting component 122 includes a first sleeve 1221 located at the center of the fixed base 12 and having a hollow structure, and a second barb 1222 connected to the first sleeve 1221 and adapted to and snapped into the first barb 1112. The first sleeve 1221 is used to facilitate the installation of the second barb 1222. When the fixed base 12 moves toward the mounting base 11, and the second barb 1222 snaps into the first barb 1112, it prevents the fixed base 12 from separating from the mounting base 11. Even when the mounting base 11 is not pressed, the exposed part of the stirring device 13 can continue to process the food.

[0041] The second limiting component 122 further includes a second sleeve 123 that is sleeved on the first sleeve 1221 and movable along the length of the first sleeve 1221. The distance between the second sleeve 123 and the second barb 1222 is less than the thickness of the first barb 1112. The second sleeve 123 is provided with a limiting protrusion 1231 that fits against the first barb 1112. The second sleeve 123 is used to separate the first barb 1112 from the second barb 1222. When the second barb 1222 is engaged with the first barb 1112, the first barb 1112 is simultaneously connected to the second barb 1222 and the second sleeve 123, preventing the first barb 1112 from connecting between the second sleeve 123 and the first barb 1112. To avoid the problem of the first barb 1112 being unable to move, when the first barb 1112 and the second barb 1222 need to be separated, the mounting base 11 is squeezed, and the first barb 1112 moves towards the limiting protrusion 1231 and passes through the limiting protrusion 1231. When the squeezing of the mounting base 11 is stopped, the reset assembly squeezes the fixing base 12, and the first barb 1112 of the mounting base 11 pulls the limiting protrusion 1231 to move. When the second sleeve 123 and the second barb 1222 are in contact, the first barb 1112 separates from the limiting protrusion 1231, so that the first barb 1112 slides over the surface of the second barb 1222, so that the first barb 1112 and the second barb 1222 are separated and the fixing base 12 is reset.

[0042] The first barb 1112 has a first inclined surface 1113 on the side near the second barb 1222. The second barb 1222 has a second inclined surface 1222 that matches the first inclined surface 1113. When the second barb 1222 is in contact with the first barb 1112, the second inclined surface 1222 of the second barb 1222 is in contact with the first inclined surface 1113 of the first barb 1112, making it easier for the second barb 1222 to be engaged with the first barb 1112.

[0043] Please refer to Figure 3 , Figure 4 , Figure 7 and Figure 8The limiting protrusion 1231 has a third inclined surface 1233 and a fourth inclined surface 1234 on both sides. The first barb 1112 presses against the third inclined surface 1233 to separate the first barb 1112 from the second barb 1222. The first barb 1112 and the fourth inclined surface 1234 are engaged to move the second sleeve 123. When the second sleeve 123 and the second barb 1222 are engaged, the first barb 1112 presses against the fourth inclined surface 1234 and separates from the fourth inclined surface 1234. The third inclined surface 1233 facilitates the first barb 1112 to pass through the limiting protrusion 1231 and engage with it. The third inclined surface 1233 facilitates the first barb 1112 to pass through and separate from the third inclined surface 1233. When the first barb 1112 is to separate from the second barb 1222... When the mounting base 11 is squeezed, the first barb 1112 of the mounting base 11 separates from the second barb 1222. The first barb 1112 of the mounting base 11 squeezes the third inclined surface 1233 of the limiting protrusion 1231. Due to the action of the third inclined surface 1233, the first barb 1112 can quickly pass through the limiting protrusion 1231. The mounting base 11 is released, and the mounting base 11 pulls the second sleeve 123 to move towards the first barb 1112. When the second sleeve 123 is in contact with the second barb 1222, the first inclined surface 1113 of the first barb 1112 slides on the fourth inclined surface 1234, so that the first barb 1112 quickly separates from the limiting protrusion 1231. After the first barb 1112 separates from the limiting protrusion 1231, the reset component squeezes the fixing base 12, so that the first barb 1112 passes through the second barb 1222, and the fixing base 12 is reset.

[0044] Please refer to Figure 11 , Figure 11 This is a perspective view of the second sleeve of the stirring mechanism of this utility model. The second sleeve 123 is also provided with a plurality of fixed protrusions 1232 extending toward the second barb 1222. The plurality of fixed protrusions 1232 are respectively located on both sides of the second barb 1222. The fixed protrusions 1232 are connected to both sides of the second barb 1222. The second barb 1222 is used to prevent the second sleeve 123 from rotating on the first sleeve 1221. At the same time, when the first barb 1112 pulls the second sleeve 123 to move, the second sleeve 123 moves toward the second barb 1222 in a defined trajectory.

[0045] Please refer to Figure 5 and Figure 6 The reset assembly includes a spring 143, with its two ends respectively sleeved on the first sleeve 1221 and the elastic plate 1111. The spring 143 has stable elasticity. When the first barb 1112 separates from the limiting protrusion 1231, the spring 143 uses its own elasticity to reverse the fixing seat 12, thereby resetting the fixing seat 12.

[0046] Please refer to Figure 3 and Figure 4 The reset assembly includes a first magnetic ring 141 located around the elastic plate 1111 and a second magnetic ring 142 that is attached to the second barb 1222 and has the opposite magnetism to the first magnetic ring 141. When the first barb 1112 separates from the limiting protrusion 1231, the magnetism of the first magnetic ring 141 and the second magnetic ring 142 repels each other, and the fixed seat 12 is pressed in the opposite direction to reset the fixed seat 12.

[0047] The fixed base 12 is also provided with a protective cover 121 around its periphery. The stirring device 13 includes a blade shaft 131 fixed on the mounting base 11 and a stirring blade 132 connected to the blade shaft 131 and located inside the protective cover 121. Both the blade shaft 131 and the stirring blade 132 are located inside the protective cover 121. During the rotation of the stirring blade 132, it prevents the user's clothes from getting tangled on the blade shaft 131 or the rotating stirring blade 132 from posing a potential threat to the person.

[0048] The periphery of the fixed base 12 is also provided with a plurality of through slots 124 extending along the height direction of the fixed base 12. The mounting base 11 also includes a third sleeve 113. The third sleeve 113 is provided with a plurality of limiting blocks 112 passing through the through slots 124. When the fixed base 12 moves toward the mounting base 11, the limiting blocks 112 limit the through slots 124 to prevent the fixed base 12 from shifting position when moving toward the mounting base 11.

[0049] Working principle:

[0050] <Example 1>

[0051] When using a blender to blend larger food items, first, press the blender. Since the mounting base 11 is fixed to the blender, pressing the blender causes the fixed base 12 to move towards the mounting base 11. The through groove 124 of the fixed base 12 moves towards the mounting base 11 along the direction of the limiting block 112. During the movement of the fixed base 12, the first magnetic ring 141 repels the second magnetic ring 142. When the second barb 1222 is engaged with the first barb 1112, the second barb 1222 has a second inclined surface 1222, and the first barb 1112 has a first inclined surface 1113, which facilitates the second barb 1222 to engage. Connected to the first inclined surface 1113, due to the repulsion between the first magnetic ring 141 and the second magnetic ring 142, when the second barb 1222 engages with the first barb 1112, the first magnetic ring 141 limiting fixing seat 12 continues to move towards the mounting seat 11. The first barb 1112 also fits against the third inclined surface 1233 of the second sleeve 123. At the same time, the stirring blade 132 inside the protective cover 121 is exposed outside the protective cover 121, facilitating the stirring of food outside the protective cover 121. After the food is stirred, the mixer continues to be squeezed, and the fixing seat 12 continues to move towards the mounting seat 11. The first barb 1112 slides on the third inclined surface 1233 and passes through the limiting protrusion 1231. At the same time, the first barb 1112 engages with the fourth inclined surface 1234 of the limiting protrusion 1231. At this point, the pressure on the mixer can be stopped. After the fixed seat 12 loses its compressive force, the first magnetic ring 141 repels the second magnetic ring 142 and pushes the fixed seat 12 away from the mounting seat 11. As the fixed seat 12 moves away from the mounting seat 11, the first barb 1112 pulls the second sleeve 123 towards the direction of the second barb 1222 through the fourth inclined surface 1234. When the second sleeve 123 engages with the second barb 1222... When the two hooks are engaged, the first hook 1112 slides over the fourth inclined surface 1234 and passes through the second hook 1222, preventing the first hook 1112 from hanging upside down on the second hook 1222, thereby separating the first hook 1112 from the second hook 1222. After the fixing seat 12 is reset, the stirring blade 132 returns to the protective cover 121 to prevent potential threats to people. With the above structure, when the first hook 1112 is engaged with the second hook 1222, the stirring blade 132 can stir the food outside the protective cover 121 without the user having to continue pressing the mixer, making it more convenient to use.

[0052] <Example 2>

[0053] When using a blender to blend larger food items, first, press the blender. Since the mounting base 11 is fixed to the blender, pressing the blender causes the fixed base 12 to move towards the mounting base 11. The through groove 124 of the fixed base 12 moves towards the mounting base 11 along the direction of the limiting block 112. During the movement of the fixed base 12, the spring 143 deforms. When the second barb 1222 engages with the first barb 1112, the second barb 1222 is provided with a second inclined surface 1222, and the first barb 1112 has a first inclined surface 1113, which facilitates the second barb 1222 engaging with the first barb 1112. On the inclined plane 1113, due to the deformation of the spring 143, it has a rebound force. When the second barb 1222 engages with the first barb 1112, the spring 143 limiting fixing seat 12 continues to move towards the mounting seat 11. The first barb 1112 is also in contact with the third inclined plane 1233 of the second sleeve 123. At the same time, the stirring blade 132 inside the protective cover 121 is exposed outside the protective cover 121, which facilitates the stirring of the food outside the protective cover 121. After the food is stirred, the mixer is continued to be squeezed, and the fixing seat 12 continues to move towards the mounting seat 11. The first barb 1112... 12 slides on the third inclined plane 1233 and passes through the limiting protrusion 1231. At the same time, the first barb 1112 engages with the fourth inclined plane 1234 of the limiting protrusion 1231. At this point, pressure on the mixer can be stopped. After the fixed seat 12 loses its compressive force, the spring 143 pushes the fixed seat 12 away from the mounting seat 11 according to its own elasticity. As the fixed seat 12 moves away from the mounting seat 11, the first barb 1112 pulls the second sleeve 123 towards the second barb 1222 through the fourth inclined plane 1234. When the second sleeve 123 and the second barb 1222 are in contact, The first barb 1112 slides over the fourth inclined plane 1234 and passes through the second barb 1222, preventing the first barb 1112 from hanging upside down on the second barb 1222, thereby separating the first barb 1112 from the second barb 1222. After the fixing seat 12 is reset, the stirring blade 132 returns to the protective cover 121 to prevent potential threats to people. With the above structure, when the first barb 1112 is engaged with the second barb 1222, the stirring blade 132 can stir the food outside the protective cover 121 without the user having to continue pressing the mixer, making it more convenient to use.

[0054] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
