Therefore, they should not be construed as limitations on this utility model.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] Example 1,

[0031] See Figures 1 to 7This utility model discloses a mixing blade that is easy to assemble and disassemble, including: a blade assembly and an unlocking member 20. The blade assembly includes a blade 11, a connector 12, a locking member 122, and a connecting shaft 13. The blade 11 is connected to the connecting shaft 13 via the connector 12. When the connecting shaft 13 rotates, it drives the blade 11 to rotate. A locking groove 121 is provided on the connector 12, and the locking member 122 is located in the locking groove 121. The connecting shaft 13 is inserted into the locking groove 121. After the connecting shaft 13 is inserted into the locking groove 121, the locking member 122 abuts against the outer periphery of the connecting shaft 13 to lock the connecting shaft 13. The bottom of the unlocking member 20 is inserted into the locking groove 121 and abuts against the outer periphery of the locking member 122. When the unlocking member 20 is subjected to force, it moves toward the locking groove 121 and presses against the locking member 122 to move the locking member 122 away from the connecting shaft 13.

[0032] Based on the above structure, during assembly, the blade 11 is connected to the connector 12, and then the connecting shaft 13 is inserted into the locking groove 121 in the connector 12. At this time, the groove wall of the locking groove 121 covers the outer periphery of the connecting shaft 13, thus initially fixing the connecting shaft 13. Since the connecting shaft 13 may fall out of the locking groove 121 during rotation, a locking member 122 is provided in the locking groove 121. The locking member 122 abuts against the outer periphery of the connecting shaft 13 to restrict the movement of the connecting shaft 13, thereby locking the connecting shaft 13. In this way, the connecting shaft 13 will not easily fall out when rotating, and it can drive the blade 11 to rotate during rotation. When the blade 11 rotates, it can process the food.

[0033] Furthermore, since the bottom of the unlocking member 20 passes through the locking groove 121 and abuts against the outer periphery of the locking member 122, when the unlocking member 20 moves toward the locking member 122 under force, it will gradually penetrate into the locking groove 121 and press against the locking member 122. This pressing force will cause the locking member 122 to displace, so that the locking member 122 is no longer tightly abutting against the connecting shaft 13. Once the locking member 122 moves away from the connecting shaft 13, the restrictive force on the connecting shaft 13 will disappear, and the connecting shaft 13 can move freely, thus presenting an unlocked state. In this way, the connecting shaft 13 can be pulled out from the locking groove 121, so that the connecting member 12 and the connecting shaft 13 are separated, and the blade 11 can be disassembled.

[0034] Specifically, when the easily detachable mixing blade of this embodiment is applied to food processors, blenders, or high-speed blenders for food mixing and processing, since the blade 11 needs to be cleaned or sharpened after long-term use, when the blade 11 needs maintenance or cleaning, the user only needs to apply external force to the unlocking member 20, forcing the unlocking member 20 to move towards the locking groove 121 until the unlocking member 20 abuts against and presses against the outer periphery of the locking member 122, causing the pressing member to move away from the connecting shaft 13 and release the connecting shaft 13. At this time, the connecting shaft 13 can be in the unlocked state, and the user can pull the connecting member 12 away from the connecting shaft 13. At the same time, the blade 11 on the connecting member 12 is also separated from the connecting shaft 13. In this way, the user can clean or maintain the blade 11 separately, which is convenient to disassemble and assemble, and easy to maintain or clean.

[0035] It should be noted that the locking member 122 in this embodiment can be an elastic arm 1222, an elastic post, or an elastic buckle, etc., which are elastic structures. In this way, when the connecting shaft 13 is inserted into the locking groove 121, the connecting shaft 13 will squeeze the locking member 122, causing it to undergo elastic deformation. Within the elastic limit, the locking member 122 will generate a restoring force. This restoring force will cause the locking member 122 to press tightly against the surface of the connecting shaft 13, just like an elastic clamp. After being opened by the connecting shaft 13, it will generate an inward clamping force, thereby locking the connecting shaft 13 tightly.

[0036] The unlocking element 20 can be a rod-shaped or block-shaped structure. One end of the unlocking element 20 is positioned outside the locking groove 121 for easy application of external force, while the other end extends into the locking groove 121 and contacts the locking element 122. When external force is applied to the unlocking element 20, it moves into the locking groove 121, thereby pressing against the locking element 122. At this time, the external force on the locking element 122 is opposite in direction to its original clamping force on the connecting shaft 13. When this pressing force is large enough, the locking element 122 will... The external force causes further deformation, reducing the clamping force on the connecting shaft 13. As the clamping force of the locking element 122 on the connecting shaft 13 decreases, the friction force on the connecting shaft 13 also decreases. When the friction force decreases to a certain extent, the connecting shaft 13 can overcome the friction force and move, thereby unlocking. It's like an elastic clamp that was originally tightly clamping the connecting shaft 13 being opened by an external force, causing the clamping force on the connecting shaft 13 to disappear, and the connecting shaft 13 can move freely.

[0037] More specifically, in this embodiment, the connector can be made of a sleeve or cover structure made of a material with a certain elasticity, such as rubber or silicone. By integrally forming a locking groove 121 inside it, and making the outer diameter of the connecting shaft 13 the same as the inner diameter of the locking groove 121, the connecting shaft 13 can be inserted into the locking groove 121. Since the connector 12 itself has a certain elasticity, after the connecting shaft 13 is inserted into the locking groove 121, the groove wall of the locking groove 121 can tightly wrap the connecting shaft 13 under the action of its own elasticity, and initially fix it. In addition, the outer diameter of the unlocking member 20 can be set to be larger than the inner diameter of the locking groove 121, so that as the unlocking member 20 gradually extends into the locking groove 121, it can gradually drive the locking groove 121 to open, and at the same time drive the locking member 122 to gradually move away from the connecting shaft 13, so as to unlock the connecting shaft 13 more quickly.

[0038] Furthermore, a mounting groove 123 is provided on the top of the connector 12, and a locking groove 121 is connected to the mounting groove 123. The locking member 122 is installed in the mounting groove 123. The connecting shaft 13 has a first end 131 and a second end 132. The first end 131 passes through the locking groove 121 and extends into the mounting groove 123. A locking part is provided on the first end 131. After the locking part extends into the mounting groove 123, it engages with the locking member 122 to lock the connecting shaft 13. The second end 132 is rotatably connected to the external structure. The unlocking member 20 passes through the mounting groove 123 and extends into the locking groove 121.

[0039] Specifically, the locking member 122 is installed in the mounting groove 123 to fix the locking member 122. Since the locking groove 121 is connected to the mounting groove 123, the first end 131 of the connecting shaft 13 can be inserted into the mounting groove 123 after passing through the locking groove 121. At this time, the locking member 122 in the mounting groove 123 can be engaged with the locking part on the first end 131 to lock the first end 131 of the connecting shaft 13, so that the connecting member 12 and the connecting shaft 13 are locked. Then, the second end 132 is connected to the external drive device to drive the connecting shaft 13 to rotate, thereby driving the blade 11 on the connecting member 12 to rotate synchronously.

[0040] More specifically, the locking part can be a slot or a latch or other structure provided on the first end 131. In this way, when the first end 131 extends into the mounting groove 123, the locking member 122 can move close to the locking part and engage with the locking part under its own elastic stress, so that the connecting shaft 13 can be more reliably positioned in the locking groove 121, reducing the possibility of accidental axial or radial movement of the connecting shaft 13 during operation, thereby improving the stability and reliability of the connection.

[0041] Of course, the locking part can also be a block or buckle on the first end 131. In this case, a slot or hole can be provided on the corresponding part of the locking member 122 to achieve the same effect.

[0042] Preferably, the locking part in this embodiment includes a snap-fit ​​groove 1311, so that when the first end 131 extends into the mounting groove 123, the locking member 122 can snap into the snap-fit ​​groove 1311 to lock the connecting shaft 13.

[0043] Furthermore, the locking groove 1311 extends circumferentially along the connecting shaft 13, and the locking member 122 includes a connecting arm 1221 and two elastic arms 1222. The connecting arm 1221 is connected between the two elastic arms 1222 and abuts against the groove wall of the mounting groove 123. The two elastic arms 1222 are used to move closer to the locking groove 1311 under the action of their own elastic force and lock into the locking groove 1311.

[0044] Specifically, since the snap-fit ​​groove 1311 extends circumferentially along the connecting shaft 13, the locking member 122 can snap into the connecting shaft 13 in the circumferential direction. Compared with locking only in a certain direction, the locking member 122 can lock with the snap-fit ​​groove 1311 in multiple directions, making installation more convenient.

[0045] More specifically, the connecting arm 1221 abuts against the wall of the mounting groove 123, and the two elastic arms 1222 are respectively connected to the two ends of the connecting arm 1221. The connecting arm 1221 stabilizes the elastic arms 1222, so that the two elastic arms 1222 can maintain a relative positional relationship during operation, avoiding excessive deformation or misalignment of the elastic arms 1222. At the same time, the abutment between the connecting arm 1221 and the wall of the mounting groove 123 also helps to better position the locking member 122 in the mounting groove 123, further enhancing the overall stability of the locking structure.

[0046] In addition, since there are two elastic arms 1222, when the first end 131 extends into the mounting groove 123, the two elastic arms 1222 can move close to the locking groove 1311 and lock into the locking groove 1311 under the action of their own elastic force. When the two elastic arms 1222 are locked into the circumferentially set locking groove 1311 at the same time, the force balance is achieved in the circumferential direction of the connecting shaft 13. Each elastic arm 1222 applies an inward locking force to the connecting shaft 13. These two forces are equal in magnitude, opposite in direction and act at different positions on the circumference. This force balance makes the connecting shaft 13 uniformly constrained in the circumferential direction, and will not loosen due to excessive or insufficient force in a certain direction, making the connecting shaft 13 more stable after being locked.

[0047] Furthermore, each elastic arm 1222 has an arc segment 12221, and the two arc segments 12221 are arranged opposite to each other and respectively connected to the snap-fit ​​groove 1311; each elastic arm 1222 is connected to the connecting arm 1221 via a bending segment 1223.

[0048] Specifically, since the snap-fit ​​groove 1311 is extended circumferentially along the connecting shaft 13, the arc segment 12221 on the elastic arm 1222 can closely adapt to the inner contour of the snap-fit ​​groove 1311, so that the elastic arm 1222 can better fit with the circumferential snap-fit ​​groove 1311, thereby providing a more stable clamping force.

[0049] More specifically, since each elastic arm 1222 is connected to the connecting arm 1221 via a bent section 1223, this bending structure increases the elastic deformation capacity of the elastic arm 1222. When the elastic arm 1222 engages or disengages from the locking groove 1311, the bent section 1223 acts as an elastic node, making it easier to bend and deform. This allows the elastic arm 1222 to better adapt to potential dimensional differences or installation errors between the connecting shaft 13 and the locking groove 1311. For example, during assembly, if the diameter of the connecting shaft 13 changes slightly or the size of the locking groove 1311 deviates slightly, the elastic deformation of the bent section 1223 allows the elastic arm 1222 to still engage smoothly into the locking groove 1311 and provide sufficient clamping force after engagement.

[0050] Furthermore, to make the connection between the connecting arm 1221 and the connector 12 more stable, a connecting groove 124 is also provided in the connector 12 in this embodiment. During assembly, the connecting groove 124 is set on the side wall of the mounting groove 123 and extends circumferentially along the mounting groove 123. After the connecting arm 1221 is installed in the connecting groove 124, the connection between the locking member 122 and the connector 12 is also tighter, making the entire locking structure more stable. When the elastic arm 1222 is engaged in the locking groove 1311 of the connecting shaft 13, the connecting arm 1221 in the connecting groove 124 can share part of the force borne by the elastic arm 1222. Therefore, when the connecting shaft 13 is subjected to a large axial tensile force, in addition to the clamping force of the elastic arm 1222 resisting the tensile force, the connecting arm 1221 can also prevent the axial displacement of the connecting shaft 13 to a certain extent by engaging with the connecting groove 124, thereby improving the load-bearing capacity and stability of the entire connecting shaft 13 locking structure.

[0051] Furthermore, the unlocking component 20 includes a pressing block 22 and an unlocking lever 21. Two elastic arms 1222 on each side of the unlocking lever 21 abut against each other and slide in cooperation with the outer periphery of the elastic arms 1222 when force is applied, so that the elastic arms 1222 move away from the locking groove 1311.

[0052] Specifically, when it is necessary to unlock the connecting shaft 13, the user presses the pressing block 22 to transmit external force to the unlocking lever 21. The unlocking lever 21 will move towards the elastic arm 1222. Since the unlocking lever 21 and the elastic arm 1222 are in abutting state, the unlocking lever 21 will slide against the outer periphery of the elastic arm 1222. At this time, the unlocking lever 21 applies an outward force to the elastic arm 1222. The direction of this force is opposite to the direction of the elastic force that the elastic arm 1222 naturally clamps into the locking groove 1311, forcing the elastic arm 1222 to move away from the locking groove 1311 until the connecting shaft 13 is unlocked.

[0053] More specifically, in this embodiment, two unlocking rods 21 can be provided. During assembly, the two unlocking rods 21 are spaced apart and connected to the bottom end of the mounting block respectively. The two unlocking rods 21 are abutted against the elastic arm 1222 respectively. In this way, after the pressing block 22 is subjected to force, it can simultaneously drive the two unlocking rods 21 to press against the elastic arm 1222, so that the elastic arm 1222 receives a greater pressure. Thus, the elastic arm 1222 can be further disengaged from the locking groove 1311 to quickly unlock the connecting shaft 13.

[0054] Furthermore, the unlocking lever 21 has a guide slope 211 at one end near the locking member 122. The guide slope 211 slides with the elastic arm 1222 to guide the elastic arm 1222 away from the locking groove 1311.

[0055] Specifically, since the guide slope 211 is inclined, when the guide slope 211 begins to contact the elastic arm 1222, the pressure applied by the guide slope 211 to the elastic arm 1222 can be decomposed into two components. One component is along the direction of the guide slope 211, which allows the unlocking lever 21 and the elastic arm 1222 to slide relative to each other. The other component is perpendicular to the direction of the guide slope 211, which can effectively push the elastic arm 1222 outward. This decomposition of forces makes the unlocking process smoother and reduces the frictional resistance between the elastic arm 1222 and the unlocking lever 21 from hindering the action of pushing the elastic arm 1222 away, thus making it easier for the elastic arm 1222 to move away from the locking groove 1311.

[0056] Furthermore, a connecting sleeve 30 is provided on the outer periphery of the connector 12, and the connecting sleeve 30 is fitted onto the outer periphery of the connector 12; one end of the unlocking member 20 is used to extend out of the connecting sleeve 30 after the connecting sleeve 30 is fitted onto the connector 12.

[0057] Specifically, since the blade assembly 10 needs to be installed inside the mixing bowl of a food processor or blender, when the device is running, the food or water inside may enter the connector 12, causing blockage of the locking groove 121 or the snap-fit ​​groove 1311, etc., resulting in problems such as the locking member 122 failing to properly lock the connecting shaft 13 or the connecting shaft 13 failing to extend into the locking groove 121. Therefore, in this embodiment, a connecting sleeve 30 is provided and fitted around the outer periphery of the connector 12 to reduce the risk of liquid inside the mixing cup entering the connector 12 and affecting the normal use of its internal structure, thereby indirectly improving the service life of the entire structure.

[0058] It should be noted that the connecting sleeve 30 can be a sleeve that matches the shape of the connecting piece 12, so that the two fit tightly together.

[0059] Example 2,

[0060] A food processor including the easily detachable mixing blades as described in Example 1.

[0061] Specifically, during assembly, the stirring blade is installed inside the stirring cup, and the connecting shaft 13 is connected to the drive device. The drive device drives the connecting shaft 13 to rotate, thereby driving the blade 11 to rotate and complete the processing of the food in the stirring cup. Since the blade 11 needs to be cleaned or sharpened after long-term use, when the blade 11 needs maintenance or cleaning, the user only needs to apply external force to the unlocking part 20, forcing the unlocking part 20 to move towards the locking groove 121 until the unlocking part 20 and the outer periphery of the locking part 122 abut against and press against the locking part 122, so that the pressing part moves away from the connecting shaft 13 to release the connecting shaft 13. At this time, the connecting shaft 13 can be in the unlocked state, and the user can pull the connecting part 12 away from the connecting shaft 13. At the same time, the blade 11 on the connecting part 12 is also separated from the connecting shaft 13. In this way, the user only needs to remove the connecting part 12 from the stirring cup to take out the blade 11 for cleaning or maintenance. The disassembly and assembly are convenient and facilitate later maintenance or cleaning.

[0062] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
