Detailed implementation manners

[0031] The following further elaborates on this application Figures 1-4 in conjunction with the appended drawings.

[0032] Embodiment 1:

[0033] An embodiment of this application discloses a mixer. Referring to Figure 1 , the mixer includes a support frame, a motor 1, a connecting seat 3, a stirring rod 2, and a fixing device 4. Among them, the motor 1 is installed on the support frame, the output end of the motor 1 faces downward and is connected to the connecting seat 3. The connecting seat 3 and the stirring rod 2 are connected by the fixing device 4. A stirring head for stirring is provided at the lower end of the stirring rod 2; the stirring head on the stirring rod 2 has blades with different structures. By replacing the stirring rod 2 through the fixing device 4, the stirring head can be quickly replaced to adapt to liquids with different concentrations.

[0034] Referring to Figure 1 and Figure 2 , specifically, the cross-sections of both the connecting seat 3 and the stirring rod 2 can be circular, and a connecting groove 31 for inserting the stirring rod 2 can be opened on the lower surface of the connecting seat 3. In this embodiment, the fixing device 4 includes a clamping block 41 fixed to the side wall of the stirring rod 2 by welding or integral molding, etc. A sliding groove 32 and a clamping groove 33 for inserting the clamping block 41 are opened inside the connecting seat 3; among them, the sliding groove 32 extends along the vertical direction and penetrates downward to the lower surface of the connecting seat 3. The clamping groove 33 extends along the circumferential direction of the connecting seat 3. The clamping groove 33 communicates with the sliding groove 32, and preferably, the upper surface of the clamping groove 33 is in the same plane as the upper surface of the sliding groove 32; during operation, align the clamping block 41 with the sliding groove 32, then insert the stirring rod 2 upward into the connecting groove 31. When the clamping block 41 slides to the end, that is, when it abuts against the side wall of the sliding groove 32, the stirring rod 2 can be rotated to drive the clamping block 41 to slide into the clamping groove 33.

[0035] Referring to Figure 1 and Figure 2In this embodiment, the fixing device 4 further includes a first limit block 42, an elastic member 43 and a driving member 44, wherein the first limit block 42 is slidably arranged in the connecting seat 3, a limit slot for the first limit block 42 to slide up and down is provided in the connecting seat 3, and a limit hole 411 for the first limit block 42 to be inserted is provided on the upper surface of the card block 41. When the card block 41 is slidably inserted into the side wall of the abutting card slot 33 away from the slide slot 32, the first limit block 42 can be inserted into the limit hole 411 under the drive of the elastic member 43, thereby limiting the card block 41 from continuing to rotate; when the card block 41 needs to be unlocked, the first limit block 42 can be driven by the driving member 44 to move upward and escape from the limit hole 411. When the connecting seat 3 rotates, the abutment between the card block 41 and the side wall of the card slot 33, and the abutment between the first limit block 42 and the card block 41 can drive the stirring rod 2 to rotate.

[0036] Reference Figure 1 and Figure 2 In the present embodiment, the elastic member 43 is a first spring, which is arranged in the limiting groove and abuts against the upper surface of the first limiting block 42. When the first limiting block 42 is inserted into the limiting hole 411, the first spring is in a compressed state, which can limit the first limiting block 42 from moving upward and out of the limiting hole 411, thereby improving the stability of fixing the blocking block 41, that is, increasing the stability of the rotation process of the stirring rod 2.

[0037] Reference Figure 1 and Figure 2 In the present embodiment, the driving member 44 is a first driving rod, which is fixed to the side wall of the first limit block 42 which is away from the central axis of the stirring rod 2, and the first driving rod is extended to the outside of the connecting seat 3. The connecting seat 3 is provided with a long groove 34 for the first driving rod to move up and down. The first limit block 42 can be driven to move up and down by sliding the first driving rod, thereby unlocking the blocking block 41.

[0038] Preferably, a chamfer is provided on the side wall at the lower end of the first limit block 42. When the block 41 slides in the slide groove 32, it can first abut the chamfer to drive the first limit block 42 to move upward. When the block 41 slides to abut the side wall of the slot 33, the first limit block 42 can slide downward under the action of the first spring.

[0039] The implementation principle of a blender in an embodiment of the present application is as follows: When the mixing head needs to be replaced, simply move the first driving rod upward with one hand and rotate the mixing rod 2 with the other hand. When the clamping block 41 rotates to abut against the side wall of the sliding groove 32, move the mixing rod 2 downward to detach the mixing rod 2. Then select a mixing rod 2 suitable for the mixing head, align the clamping block 41 with the sliding groove 32, move the mixing rod 2 upward and insert it into the connecting seat 3. When the clamping block 41 slides to abut against the side wall of the sliding groove 32, rotate the mixing rod 2 to drive the clamping block 41 to slide into the clamping groove 33. When the clamping block 41 slides to abut against the side wall of the clamping groove 33, the first limiting block 42 is inserted into the limiting hole 411 to fix the mixing rod 2.

[0040] Embodiment 2:

[0041] The difference between this embodiment and Embodiment 1 lies in the different limiting methods for the clamping block 41. The mixing rod 2 can be fixed to the connecting seat 3 or detached from the connecting seat 3 with one hand. Refer to Figure 3 , in this embodiment, a counterbore 35 is further formed on the connecting seat 3. The counterbore 35 is located below one end of the clamping groove 33 away from the sliding groove 32. Thus, when the clamping block 41 rotates with the mixing rod 2 and slides to abut against the side wall of the clamping groove 33, it can move downward under the action of gravity and fall into the counterbore 35. Therefore, when the connecting seat 3 rotates with the motor 1, the mixing rod 2 can be driven to rotate through the clamping block 41.

[0042] Further preferably, a second spring 45 is fixed to the bottom wall at the upper end of the connecting groove 31 of the connecting seat 3. Optionally, a stopper can be fixed to the lower end of the second spring 45. When the clamping block 41 is located in the counterbore 35, the second spring 45 is in a compressed state, so as to drive the clamping block 41 to abut tightly against the lower side wall of the counterbore 35 and limit the upward sliding of the clamping block 41, improving the stability of the mixing rod 2 during operation.

[0043] The implementation principle of a blender in an embodiment of the present application is as follows: When the mixing head needs to be replaced, first control the mixing rod 2 to slide upward so that the clamping block 41 enters the clamping groove 33. Then rotate the mixing rod 2 so that the clamping groove 33 slides into the sliding groove 32. Then the clamping block 41 can be slid downward to detach the mixing rod 2. Next, select a mixing rod 2 suitable for the fixed mixing head, align its clamping block 41 with the sliding groove 32, insert the mixing rod 2 into the connecting groove 31, and then rotate the mixing rod 2 until the clamping block 41 slides to abut against the side wall of the clamping groove 33, and then release the mixing rod 2. At this time, the clamping block 41 falls into the counterbore 35 under the action of gravity and the second spring 45.

[0044] Embodiment 3:

[0045] The fixing device 4 in this embodiment is different from that in Embodiment 1 and Embodiment 2. Compared with Embodiment 1, the disassembly method in this embodiment is more convenient; compared with Embodiment 2, the installation stability of the mixing rod 2 in this embodiment is better.

[0046] Refer to Figure 4 , specifically, in this embodiment, the fixing device 4 includes a third positioning rod 46 and a third spring 47. The third positioning rod 46 is slidably arranged on the stirring rod 2 along the direction close to or away from the central axis of the stirring rod 2. The third spring 47 is arranged inside the stirring rod 2, and the third spring 47 is arranged at one end of the third positioning rod 46 close to the central axis of the stirring rod 2; preferably, two third positioning rods 46 and third springs 47 are symmetrically arranged at the upper end of the stirring rod 2.

[0047] Refer to Figure 4 , a relief groove 36 for the third positioning rod 46 to slide into is formed in the connecting seat 3, and a positioning groove 37 for the third positioning rod 46 to pass through is formed. The relief groove 36 penetrates to the lower surface of the connecting seat 3; one end of the third positioning rod 46 away from the third spring 47 is set as an arc surface. When the stirring rod 2 is inserted into the connecting seat 3, it presses on the two third positioning rods 46, so that the third positioning rod 46 can enter the relief groove 36 accordingly. When the end of the stirring rod 2 abuts against the bottom wall of the connecting groove 31, the third positioning rod 46 penetrates through the positioning groove 37 under the action of the third spring 47, so that the connecting seat 3 can drive the stirring rod 2 to rotate through the third positioning rod 46; when it is necessary to disassemble the stirring rod 2, only need to press the third positioning rod 46 in the same way, and then a downward force can be applied to the stirring rod 2 to take out the stirring rod 2.

[0048] Refer to Figure 4 , further, a third guiding block 461 is fixed on the side wall of the third positioning rod 46, and a third guiding groove for the third guiding block 461 to slide is formed in the stirring rod 2. The third guiding block 461 slides in the third guiding groove, which can limit the third positioning rod 46 from disengaging from the stirring rod 2.

[0049] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
