Fig. 1 is a schematic perspective view of an embodiment of a blender blade assembly 10 of the present application. Fig. 2 is a schematic cross-sectional view of the blender blade assembly 10 shown in fig. 1. The blender blade assembly 10 of the present embodiment includes a blender blade 100, a counter balance 200, and a counter balance 300. In some embodiments, the stirring blade 100 includes a blade shaft 110 and a stirring blade head 120. Specifically, the stirring blade 120 is assembled to one end of the cutter shaft 110. The balance member 200 is fixed to the arbor 110, and a cavity 210 is provided in the balance member 200. The balancing liquid 300 is disposed inside the cavity 210. The utility model provides a stirring sword subassembly 10 produces centrifugal force at arbor 110 pivoted in-process, makes the interior balancing liquid 300 of cavity 210 can compensate arbor 110 pivoted irregular motion, reduces the noise that the mixer vibrations produced to a certain extent, improves the stability and the stirring efficiency of mixer, promotes user's use experience.

Fig. 3 is an exploded view of the blender blade assembly 10 of fig. 1. In some embodiments, as shown in fig. 2 and 3, the balance member 200 and the cavity 210 are symmetrically disposed with respect to the arbor 110. The symmetrically arranged balancing piece 200 and the cavity 210 can meet the requirement of the balancing performance of the stirrer, and the vibration amplitude of the stirrer and the noise generated by the vibration are reduced to a certain extent; and the balance piece 200 and the cavity 210 can be arranged at different positions of the cutter shaft 110 to adjust the balance of the cutter shaft 110, so that the flexibility is good. Alternatively, the balancing member 200 may be cylindrical and symmetrical about the diameter of the arbor 110 (i.e. the diameter of the arbor is taken as the symmetry axis), and it is understood that the center of the cross section of the balancing member 200 coincides with the axis of the arbor 110, and the balancing member 200 may be of other shapes. In some embodiments, the balance 200 includes mounting holes 240 extending up and down, and the cavity 210 is disposed around the mounting holes 240. Further, as shown in fig. 3, the cavity 210 is in a circular column shape, and the cross section of the cavity 210 is in a circular ring shape. The circular cavity 210 makes the internal balancing liquid 300 uniformly distributed along the circumferential direction of the cavity 210, so that the circumferential weight of the cutter shaft 110 is uniform, the stability of the rotation of the cutter shaft 110 is further improved, and the service life of the stirrer is prolonged. Correspondingly, the cavity 210 is in a shape consistent with the shape of the balance piece 200, is in a circular column shape with a mounting hole 240 in the center, and the cavity 210 is axisymmetric relative to the diameter of the cutter shaft 110 (i.e. the diameter of the cutter shaft is taken as a symmetry axis), so that the balance piece has better circumferential weight uniformity. In some embodiments, the cavity 210 is proximate to an outer sidewall 221 of the balance 200 relative to the arbor 110. The cavity 210 is far away from the cutter shaft 110, the movement radius is larger, the centrifugal force acting on the balancing liquid 300 is larger, and the balancing and stabilizing effect of the balancing liquid 300 is better. In some embodiments, the cavity 210 extends from a position near the mounting hole 240 to a position near the outer sidewall 221, so that the cavity 210 has a larger volume, and can accommodate a larger volume of the balancing liquid 300, and the balancing effect is better.

In some embodiments, the balance member 200 includes a first balance weight 220 and a second balance weight 230 sealingly assembled above the first balance weight 220, the first balance weight 220 and the second balance weight 230 enclose a cavity 210, and the balance liquid 300 is disposed in the cavity 210. In some embodiments, as shown in fig. 2 and 3, the first weight 220 includes an outer sidewall 221, and the annulus of the outer sidewall 221 connecting with the second weight 230 includes a positioning protrusion 221a, the positioning protrusion 221a protruding upward; accordingly, the second balance weight 230 includes a positioning groove (not shown) that mates with the positioning protrusion 221 a. The first balance block 220 and the second balance block 230 are in limit fit connection with the positioning groove through the positioning protrusion 221a, and the structure is simple and the positioning effect is good. In some embodiments, the first balance weight 220 and the second balance weight 230 are sealed by ultrasonic welding, so as to form a sealed cavity 210, so that the sealing effect is good, the balance liquid 300 is not easy to evaporate or run off, and the balance effect is ensured. In some embodiments, the first weight 220 and the second weight 230 are made of plastic, which has low cost and low weight, and ensures the user experience. In some embodiments, the second balance block 230 is provided with a filling hole 231 penetrating up and down, and the filling hole 231 communicates with the cavity 210 for filling the balance liquid 300. The liquid injection hole 231 is convenient for injecting and supplementing the balance liquid 300, and has simple structure and convenient use. In some embodiments, the second weight 230 includes a plug 232 disposed within the fill hole 231, the plug 232 being removably sealingly coupled to the fill hole 231. Optionally, the material of the hole plug 232 is rubber, so that the sealing performance is good.

Referring to fig. 2, in some embodiments, the balancing fluid 300 comprises 40% -70% of the volume of the cavity 210. Preferably, the balancing liquid 300 may occupy 40%, 50%, 60% or the volume of the cavity 210

70%. It can be appreciated that, on the one hand, if the balancing liquid 300 occupies a smaller volume of the cavity 210, the effect of stabilizing the mixer is poor if the amount of the balancing liquid 300 is smaller; on the other hand, if the balancing liquid 300 occupies a larger volume of the cavity 210, the amount of the balancing liquid 300 is larger, and the space margin except for the balancing liquid 300 in the cavity 210 is smaller, so that the rotation amplitude of the balancing liquid 300 is smaller and the effect of stabilizing the mixer is poor when the balancing liquid 300 rotates along with the cutter shaft 110. The balance liquid 300 occupies a moderate volume ratio of the cavity 210, so as to avoid the influence of excessive or insufficient balance liquid 300 on the balance effect. It should be noted that, in the case where the balance liquid 300 occupies a certain volume ratio of the cavity 210, the larger the volumes of the balance liquid 300 and the cavity 210, the better the balance effect, the comprehensive consideration of the volume and the weight of the mixer is needed, so as to ensure that the user has better use experience when holding or carrying the mixer.

It will be appreciated that, in the case that the volumes of the cavity 210 and the balancing liquid 300 are fixed, in order to ensure that the centrifugal force generated in the working state of the rotation of the arbor 110 makes the rotation amplitude of the balancing liquid 300 larger, thereby improving the working stability of the mixer, the balancing liquid 300 should be a liquid fluid having a certain fluidity at room temperature. Further, the viscosity of the liquid fluid is small, so that the balancing liquid 300 can be thrown to the outer sidewall 221 during rotation to compensate for irregular movement caused by rotation of the cutter shaft 110. Alternatively, the balancing fluid 300 may be water, or may be an oil or other liquid fluid.

With continued reference to fig. 2, in some embodiments, the arbor 110 includes oppositely disposed first and second ends 111, 112. In the working state that the cutter shaft 110 is assembled to the mixer, the first end 111 is located at the top end of the cutter shaft 110, the second end 112 is located at the bottom end of the cutter shaft 110, the mixing cutter head 120 is assembled to the second end 112, and the driving device is assembled to the first end 111. In some embodiments, the stirring blade assembly 10 includes an upper housing 400, the upper housing 400 enclosing a receiving cavity 410 having a volume, the first end 111 and the balance member 200 being located within the receiving cavity 410, the upper housing 400 functioning to protect the balance member 200 and the arbor 110. Further, the balance member 200 is disposed near the first end 111, and the balance member 200 is near the bottom of the upper housing 400 with respect to the top of the upper housing 400. Compared with the balance piece 200 arranged outside the upper shell 400, the balance piece 200 is arranged inside the upper shell 400, so that the space of the stirrer can be saved, and the balance piece 200 is close to the middle part of the cutter shaft 110 and the cutter head, so that the vibration of the end part of the cutter shaft 110 and the cutter head can be reduced.

Referring to fig. 1, in some embodiments, the stirring blade assembly 10 includes a shaft sleeve 500 sleeved outside the cutter shaft 110, and a top end of the shaft sleeve 500 is connected with the upper housing 400. In some embodiments, the blender blade assembly 10 includes a blade tip protective sleeve coupled to the shaft sleeve 500. Specifically, the sleeve 500 includes a connection end 510 at the top end of the sleeve 500, and the upper housing 400 includes a connection part 420, and the connection end 510 is connected to the connection part 420. In some embodiments, the connection end 510 is inserted into the connection portion 420 and extends upward into the accommodating cavity 410, so that the connection is reliable and the structure is simple. In some embodiments, the balance member 200 and the connection end 510 or the connection part 420 have a gap in the up-down direction, so that collision friction with the shaft sleeve 500 during the up-down movement of the cutter shaft 110 is prevented, and the working safety of the mixer is ensured. It can be appreciated that the above-mentioned gap needs to be determined according to the up-and-down motion amplitude of the balancing member 200, so as to meet the safety requirement, which is not limited in this application.

In some embodiments, the lower end surface of the balance member 200 is provided with an upwardly concave relief 222, and the relief 222 is located above the top end of the sleeve 500. It can be understood that the avoidance portion 222 is an avoidance space with a certain volume, and can avoid the connection end 510 of the shaft sleeve 500 or the connection portion 420 of the upper housing 400, so as to provide a space margin for the up-and-down movement of the cutter shaft 110. In some embodiments, the relief 222 is proximate the arbor 110 relative to the outer sidewall 221 of the balance member 200. The connection between the connection end 510 and the connection portion 420 is close to the arbor 110, and the avoidance portion 222 is correspondingly close to the arbor 110. In some embodiments, the relief 222 includes a first relief wall 222a and a second relief wall 222b, the first relief wall 222a extends obliquely from top to bottom in a direction away from the arbor 110, and the second relief wall 222b extends radially from an upper edge of the first relief wall 222a in a direction toward the arbor 110. It can be appreciated that the second avoidance wall 222b extends in the horizontal direction, the first avoidance wall 222a is circumferentially disposed along the second avoidance wall 222b, and the avoidance portion 222 is recessed upward. The first avoiding wall 222a disposed obliquely can increase the space allowance of the movement of the cutter shaft 110 while ensuring the volume of the cavity 210. It can be appreciated that if the lower end surface of the balance member 200 is disposed away from the shaft sleeve 500 for avoiding the shaft sleeve 500 or the upper housing 400, on one hand, the balance member 200 collides with the upper housing 400 under the condition of ensuring that the volume of the cavity 210 is unchanged, and on the other hand, the volume of the cavity 210 is reduced under the condition of ensuring that the balance member 200 does not collide with the upper housing 400, so that the volume of the balance liquid 300 is reduced, and the balance effect is affected. In some embodiments, the cavity 210 is correspondingly provided with an inclined avoidance surface near the first avoidance wall 222a, so as to ensure the connection strength between the side wall of the cavity 210 and the first avoidance wall 222 a.

In some embodiments, the balance member 200 is secured to the arbor 110, preventing displacement of the balance member 200 relative to the arbor 110 from affecting the effect of stabilizing the blender or affecting other components of the blender. In some embodiments, the balancing member 200 includes a mounting hole 240 penetrating up and down, the arbor 110 is fixedly inserted into the mounting hole 240, and the mounting hole 240 and the arbor 110 are coaxially disposed in the axial direction of the arbor 110. The mounting holes 240 and the cutter shaft 110 are coaxially arranged to ensure that the gravity center of the balancing piece 200 is positioned on the axis of the cutter shaft 110, the stability of the cutter shaft 110 in a rotating state is higher, the assembly efficiency of the balancing piece 200 is higher, and the installation is convenient. In some embodiments, the mounting hole 240 and the arbor 110 may be connected by threads, or may be connected by a key or interference, so that the assembly and disassembly are convenient, the structure is simple, and the processing is easy. In other embodiments, the mounting holes 240 and the arbor 110 may be connected by welding, riveting, or bonding, so that the connection strength is high, and the connection is firm and reliable.

On the basis of the above embodiment, the stirring blade assembly 10 includes the limiting member 600 clamped on the cutter shaft 110, where the limiting member 600 is disposed protruding with respect to the surface of the cutter shaft 110, and the limiting member 600 can further improve the fixing effect of the balancing member 200, and prevent the balancing member 200 from being displaced in the vertical direction to affect the effect of the balancing stirrer. In some embodiments, the stop 600 abuts the lower end face and/or the upper end face of the balance 200. Correspondingly, the cutter shaft 110 is provided with a limiting groove 113, the limiting groove 113 is arranged around the cutter shaft 110, and the limiting groove 113 is positioned above and/or below the connection part of the balance piece 200 and the cutter shaft 110. The stopper 600 is clamped in the limiting groove 113, so that the position of the balance 200 can be limited. Further, as shown in fig. 3, the limiting member 600 has a circular ring shape with at least one notch 610, and the limiting member 600 is in limiting fit with the limiting groove 113 through the notch 610. Specifically, the limiting member 600 is assembled to the limiting groove 113 through the notch 610. In some embodiments, the edges of the notch 610 are rounded to facilitate assembly of the stop 600. Alternatively, the material of the stopper 600 may be stainless steel to improve the strength and the service life of the stopper 600.

Referring to fig. 3, in some embodiments, the surface of the arbor 110 is provided with a roughness 114, and the roughness 114 is located at the junction of the balance 200 and the arbor 110. In this way, the roughness between the cutter shaft 110 and the balance member 200 can be increased, the friction force between the balance member 200 and the cutter shaft 110 is larger in the process of rotating the cutter shaft 110, the skid resistance is good, and the balance member 200 is prevented from being separated from the cutter shaft 110 to a certain extent. In some embodiments, the roughness 114 may be knurled. The knurling can be straight knurling or reticulation. In other embodiments, the roughness 114 may be a raised tooth-like structure or other structure that may increase the friction between the arbor 110 and the balance 200. In some embodiments, the surface of the balance member 200 at the connection with the arbor 110 is smooth, and may be in interference fit with the roughened portion 114, further improving the firmness of the connection.

In some embodiments, the stirring blade assembly 10 includes a damper ring 700, the damper ring 700 is sleeved on the cutter shaft 110, and the damper ring 700 is clamped between the balance member 200 and the limiting member 600. The shock-absorbing ring 700 can reduce friction between the balance member 200 and the stopper 600, and plays a role of buffering and shock-absorbing. In some embodiments, shock ring 700 is annular in shape. Since the limiting member 600 has a circular shape with at least one notch 610, that is, the limiting member 600 is not completely circular in the circumferential direction, the center of gravity of the balancing member 200 may be shifted in the circumferential direction during the rotation of the arbor 110, thereby affecting the balance and stabilizing the mixer, and the circular damping ring 700 may reduce the impact of the limiting member 600 with the notch 610 on the balancing member 200. Alternatively, the material of the shock ring 700 may be plastic or metal.

The foregoing description of the preferred embodiments of the present utility model is not intended to limit the utility model to the precise form disclosed, and any modifications, equivalents, improvements and alternatives falling within the spirit and principles of the present utility model are intended to be included within the scope of the present utility model.
