[0002] A blender is an efficient kitchen appliance whose main function is to break down food and release more nutrients, making the vitamins, minerals, dietary fiber and other nutrients in the food easier to be absorbed by the human body.

[0003] Blenders usually have high-speed rotating blades that can blend, grind and mix food to a very fine state. After the blender is finished blending, there are usually food residues attached to the blades and the wall of the blender cup. The current common cleaning method is to add clean water to the blender, drive the blade to rotate, and use the water flow to achieve self-cleaning of the blade and the wall of the cup. Since the blade and the water flow rotate in the same direction, the cleaning effect of the residue on the blade is poor, and it is often necessary to remove the blade separately for cleaning, which makes the overall cleaning efficiency poor.

The first cleaning part 53 and the second cleaning part 54 are installed on the side wall of the connecting rod 52 along the axial direction, and the first cleaning part 53 is located on the side close to the connecting rod 52 facing the cleaning cover 51. The first cleaning part 53 and the connecting rod 52 are fixedly plugged, and the second cleaning part 54 and the connecting rod 52 are rotationally matched. The connecting assembly 55 is used to fix the first cleaning part 53 and the second cleaning part 54. The outer sides of the first cleaning part 53 and the second cleaning part 54 are both installed with cleaning parts 531 for abutting against the inner wall of the cup body 41. In this embodiment, the cleaning parts 531 are soft bristles.

[0056] The connection assembly 55 is provided so that the cleaning assembly 5 has two states. When the connection assembly 55 is not connected to the two cleaning parts, the driving member 3 only drives the first cleaning part 53 to rotate, and the second cleaning part 54 is in a relatively static state, which is the first cleaning state for cleaning the stirring blade 2; when the connection assembly 55 connects and fixes the two cleaning parts, the driving member 3 drives the first cleaning part 53 and the second cleaning part 54 to rotate at the same time, which is the second cleaning state for cleaning the inner wall of the cup body 41.

[0057] The first cleaning part 53 includes a first ring sleeve 532 and an extension frame 533 circumferentially arranged outside the first ring sleeve 532. The first ring sleeve 532 is an annular sleeve with two ends passing through it as a whole, and its inner diameter is adapted to be plugged with the connecting rod 52. The inner wall of the first ring sleeve 532 is symmetrically provided with limiting ribs 5321 along the axis.

The inner side wall of the second annular sleeve 541 has a fixing groove 5411 that cooperates with the outer ring of the rotating bearing 524, so as to realize the rotational cooperation between the second cleaning part 54 and the connecting rod 52.

[0060] Reference Figure 6 The cleaning cover 542 has a covering chamber covering the stirring blade 2, and a flow gap 5421 is formed between the inner wall of the cleaning cover 542 and the stirring blade 2. By setting the flow gap 5421, the distance between the stirring blade 2 and the inner wall of the cup body 41 is shortened, the friction force at the outer side of the stirring blade 2 is increased, so that the eddy current and turbulence are enhanced, and the flushing effect of the fluid on the blade surface is enhanced.

[0061] The inner wall of the cleaning cover 542 is provided with raised portions 5422 at intervals along the circumferential direction of the axis, and the raised portions 5422 extend in the tangential direction of the inner wall of the cleaning cover 542, and the extending direction is consistent with the direction of rotation of the water flow. The raised portion 5422 is provided with a blocking portion 5423 for blocking the water flow, and the blocking portion 5423 has an arc-shaped groove 54231. The opening direction of the arc-shaped groove 54231 corresponds to the direction of the fluid. Under the action of the stirring blade 2, the fluid rotates circumferentially and impacts the arc-shaped groove 54231, and a reverse reflux is generated through the arc-shaped groove 54231, and the reflux can impact the surface of the stirring blade 2, further improving the effect of cleaning the residue.

[0062] Reference Figure 7 The side wall of the cleaning cover 542 is horizontally penetrated with a water outlet hole 5424. The centrifugal force generated by the rotation of the stirring blade 2 discharges the water from the water outlet hole 5424. The top of the outer side of the cleaning cover 542 is provided with a receiving chamber 5425, and the receiving chamber 5425 and the driving member 3 are coaxially arranged. A plurality of blades 528 are fixedly mounted on the side wall of the connecting rod 52 in the receiving chamber 5425.

The bottom wall of the receiving chamber 5425 is provided with a flow hole 5426 connected to the covering chamber, and the flow hole 5426 corresponds to the outer side of the stirring blade 2 in the axial direction.

[0063] When the connecting rod 52 drives the blade 528 to rotate, negative pressure is formed in the accommodating chamber 5425, and water flows into the covering chamber along the circulation hole 5426. After the water in the accommodating chamber 5425 is discharged, the water in the cup body 41 is automatically replenished to the accommodating chamber 5425. The cleaning cover 542 is equipped with sealing screens at the water outlet hole 5424 and the circulation hole 5426 to reduce the probability of residue entering the accommodating chamber 5425.

[0066] Reference Figure 8 and Fig. 9 , the connecting groove 5412 extends in the circumferential direction, and the arc length of the connecting groove 5412 is greater than that of the connecting block 552, so that the connecting block 552 can rotate in the connecting groove 5412. A contact slope 54121 is provided on the top sidewall of one end of the connecting groove 5412, and the contact slope 54121 is inclined inwardly toward the first cleaning portion 53. The top of the connecting block 552 has a disengagement slope 5521 that cooperates with the contact slope 54121, so that when the connecting block 552 slides to one side of the contact slope 54121, the disengagement slope 5521 and the contact slope 54121 are contacted, and the sliding rod 551 is pulled upward to realize the disengagement of the connecting block 552 from the connecting groove 5412.

[0067] Reference Figure 4 and 10 In order to improve the stability of the cleaning cover 542 in the first cleaning state, an abutment sheet 543 is also slidably mounted on the cleaning cover 542. The abutment sheet 543 is used to be inserted into the adjacent reinforcing ribs 411 to limit the rotation of the cleaning cover 542 due to the rotation of the water flow.

[0068] The top of the cleaning cover 542 is provided with a radial slide groove 5427 for slidingly installing the abutting piece 543. A driving piece 545 parallel to the abutting piece 543 is also slidably installed in the radial slide groove 5427, and a driving gear 544 is provided between the driving piece 545 and the abutting piece 543, and the driving gear 544 is rotatably installed in the radial slide groove 5427. The driving piece 545 and the abutting piece 543 both have tooth surfaces that match the driving gear 544, and the driving piece 545 and the abutting piece 543 are both limited in the radial slide groove 5427.

[0069] One end of the radial slide groove 5427 passes through the second ring sleeve 541 and communicates with the sliding groove 525 of the connecting rod 52. Before the two cleaning parts are fixed, the driving piece 545 is located below the limiting piece 527. The driving piece 545 has a downwardly inclined driving inclined surface 5451 at the end of the sliding groove 525. When the sliding rod 551 moves downward, the limiting piece 527 abuts against the driving piece 545, so that the driving piece 545 moves away from the sliding rod 551, and the driving piece 545 drives the driving gear 544 to rotate, and the driving gear 544 drives the abutting piece 543 to move away from the reinforcing rib 411, so that the abutting state between the abutting piece 543 and the reinforcing rib 411 is released. The abutting piece 543 is disengaged and the connection and fixation of the two cleaning parts are simultaneously achieved through the sliding rod 551.

[0070] The implementation principle of the blender that is easy to clean in the embodiment of the present application is as follows: before the cleaning operation, the push block 412 is slidably moved to unlock the rotating handle 422 so that the cup cover 42 is removed from the cup body 41;

[0071] Then, the cleaning cover 51 is positioned and inserted on the side of the cup cover 42 facing the rotating handle 422, and one end of the connecting rod 52 with the arc plate 521 passes through the insertion hole 512 from the other side of the cup cover 42 to the placement ring groove 511, and then the rotating sleeve 561 is rotated to rotate the covering arc plate 513 to cover the insertion hole 512; clean water is added to the cup body 41, and hot water and cleaning aids can be added to improve the cleaning effect, and then the cleaning cover 51 is reinstalled on the cup body 41, and the bottom of the connecting rod 52 is correspondingly plugged into the plug-in end 31 of the driving member 3 to achieve a fixed connection between the connecting rod 52 and the driving member 3;

[0072] At this time, the cleaning assembly 5 is in the first cleaning state, the second cleaning part 54 and the connecting rod 52 are in rotational cooperation, and the abutment sheet 543 abuts between adjacent reinforcing ribs 411. The driving member 3 is started, and the connecting rod 52 only drives the first cleaning part 53 to rotate, and the cleaning cover 542 is in a relatively static state. When the water flows through the flow gap 5421, the turbulence generated by the setting of the protrusion 5422 impacts the residue on the stirring blade 2. At the same time, the flowing water in the cleaning cover 542 is discharged along the water outlet 5424, and then the water source is pumped from the outside of the cleaning cover 542 into the cleaning cover 542 through the blades in the accommodating chamber, which has an impact effect on the stirring blade 2 from top to bottom;

[0073] After completing the cleaning of the stirring blade 2, press the sliding rod 551 to make the abutment sheet 543 move away from the reinforcing rib 411, and at the same time, the connecting block 552 is also radially inserted into the connecting groove 5412 to realize the limited connection between the cleaning cover 542 and the connecting rod 52, start the driving member 3, and the connecting rod 52 simultaneously drives the first cleaning part 53 and the second cleaning part 54 to rotate, and the cleaning parts 531 on the outside of the two cleaning parts sweep and clean the inner wall of the cup body 41.

[0074] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
