Disclosure of utility model

The application provides a stirring knife assembly and a cooking machine, which can be conveniently detached for cleaning, and the knife assembly cannot fall down during pouring, so that the stirring knife assembly is safe and reliable.

In one aspect, the present application provides a blender blade assembly. The stirring blade assembly includes: the rotating shaft comprises a driving section, the driving section comprises a plurality of convex edges extending along the up-down direction, the convex edges are gradually deflected along the circumferential direction of the driving section, and the deflection direction of the convex edges from top to bottom is opposite to the rotating direction of the rotating shaft; the cutter assembly is detachably arranged on the rotating shaft and comprises a cutter rest and a cutter blade fixed on the cutter rest, the cutter blade or the cutter rest is provided with a driving hole matched with the driving section, the driving hole comprises a plurality of convex angles vertically extending along the up-down direction, and the convex angles are respectively in butt fit with the convex edges; the driving section is provided with a retaining groove positioned above the driving hole, and the width of the retaining groove in the up-down direction is larger than the thickness of the driving hole. Because the cutter component is detachably arranged on the rotating shaft, when the stirring cup component needs to be cleaned after being used, a user rotates the cutter component along the deflection direction of the convex edge to detach the cutter component, and the cleaning is thorough, so that dead angles which cannot be cleaned are not existed in the stirring cup component, and the conditions of bacteria breeding and peculiar smell generation are effectively avoided; meanwhile, the driving section comprises a convex edge deflected along the circumferential direction, the driving hole comprises a plurality of convex angles extending vertically along the up-down direction, and the convex edge plays a limiting role on the convex angles in the rotation process of the knife assembly along with the rotating shaft, so that the knife assembly can be prevented from being separated from the rotating shaft, and the installation and the disassembly are convenient; and, because the drive section is equipped with the retaining groove that is located the drive hole top, and the retaining groove is greater than the thickness of drive hole in upper and lower ascending width, like this when the desizing, the knife tackle is in the gliding in-process in pivot top, knife rest or blade form the drive hole the part fall into the retaining groove, thereby can not continue to slide out along the direction of extension of chimb, the chimb that is located retaining groove top (the one end that the chassis was kept away from to the pivot) staggers with the lobe of drive hole, obviously, this part chimb radially protrudes in the side between 2 adjacent lobes, so, the part of drive section in retaining groove top can play spacing effect to the knife tackle, avoid the knife tackle to fall from the pivot when the desizing.

Further, the direction of deflection of the plurality of flanges from top to bottom is opposite to the direction of rotation of the knife assembly. In this way, when the cutter assembly rotates along with the cutter shaft, the convex angle is pressed against the convex edge in the direction opposite to the rotation direction of the cutter shaft (namely, the deflection direction of the convex edge from top to bottom), so that the convex edge is abutted against at least part of the convex angle, and the pressing force generated by the convex edge on the convex angle has downward component force, that is, the convex edge deflecting along the circumferential direction has downward limiting effect on the cutter assembly, so that the cutter assembly cannot be separated from the rotating shaft along the upward axial direction in high-speed rotation.

Further, a ratio of the width of the backstop groove to the thickness of the drive hole is between 1.1 and 1.5. By limiting the ratio to be greater than or equal to 1.1, when the slurry is poured, the convex edge above the retaining groove and the convex angle of the driving hole are staggered to play a limiting role on the cutter assembly more reliably along with the fact that the part of the cutter assembly forming the driving hole falls into the retaining groove in the process of sliding towards the top end of the rotating shaft, so that the cutter assembly is prevented from falling off from the rotating shaft during slurry pouring; by defining the ratio to be less than or equal to 1.5, the precession effect is prevented from being affected by too wide of the retaining groove when the knife assembly is rotatably mounted to the spindle, and the knife assembly can be more smoothly rotated in place on the spindle.

Further, the upper end of the retaining groove is provided with a retaining surface, and the retaining surface is perpendicular to the extending direction of the convex angle. Therefore, by arranging the retaining surface, the cutter assembly can be better prevented from falling off from the rotating shaft during slurry pouring.

Further, a guide part is arranged at the lower end of the backstop groove, and the radial dimension of the guide part gradually increases from top to bottom. Thus, by providing the guide portion, the blade assembly can be more smoothly mounted to the rotating shaft under the guide of the guide portion.

Further, the retaining groove is provided with a retaining surface and a guide portion, the retaining surface is arranged at the upper end of the retaining groove, the guide portion extends from the upper end to the lower end of the retaining groove, and the radial dimension of the guide portion gradually increases from top to bottom. Therefore, by arranging the retaining surface, the cutter assembly can be better prevented from falling off from the rotating shaft during slurry pouring; by providing the guide portion, the knife assembly can be mounted to the rotating shaft more smoothly.

Further, the angle of deflection of the top end of the convex edge relative to the bottom end is between 15 and 75 degrees, and the height of the driving section in the vertical direction is between 8 and 40 millimeters; and/or the thickness of the driving hole in the vertical direction is between 1 mm and 6 mm. Through limiting the deflection angle of the convex edge and the height of the driving section, the convex edge has a good limiting effect on the cutter assembly, the cutter assembly cannot be separated from the rotating shaft in the rotating process or the slurry pouring process, and the cutter assembly is convenient to install and detach; by defining the thickness of the drive hole, the mating of the drive hole with the spindle is made stronger and more wear resistant, thereby increasing the life and stability of the knife assembly.

Further, the knife assembly further comprises a fixing washer, the knife blade is arranged between the knife rest and the fixing washer, the knife blade, the knife rest and the fixing washer are fixed through welding respectively, and the knife blade and the fixing washer jointly form the driving hole. Like this can not have the clearance between blade and knife rest and stationary washer to avoid food material residue to hide between the three, and knife tackle simple structure, stability, manufacturing cost is lower, in addition, because blade and stationary washer form the drive hole jointly, thereby can increase blade wearability, promoted knife tackle's life-span and stability.

Further, the deflection angle of the convex edge is H in unit length of the driving section, and the value of H ranges from 1 to 3. Thus, the knife component can be easily arranged on the rotating shaft, and the convex edge knife component has a better limiting effect.

Further, the rotating shaft further comprises a limiting section arranged above the driving section, and the tool rest comprises a limiting hole matched with the limiting section.

A bearing 24 and an oil seal 26 are arranged between the rotating shaft 22 and the bearing sleeve 23. In one embodiment, the stirring cup 10 comprises a cup body 11 and a cup holder 12 assembled at the bottom of the cup body 11, and the bottom plate 21 is fixed between the cup body 11 and the cup holder 12. The cup 11 and the cup holder 12 are assembled together by screw threads or a screw-fastening, etc., and are not limited thereto. The chassis 21 is provided with electronic components such as a heating element (not labeled), a temperature controller (not labeled), a temperature sensor (not labeled) and the like.

In the illustrated embodiment, the cross section of the shaft 22 is square, and the flange 221 is formed by four corners of the square cross section. In another embodiment, the shaft 22 may be triangular or polygonal. In yet another embodiment, the shaft 22 includes a cylindrical portion, and the flange 221 is formed by protruding a surface of the cylindrical portion.

The cutter assembly 30 is detachably mounted on the rotating shaft 22, the cutter assembly 30 comprises a cutter holder 31 and a cutter blade 32 fixed on the cutter holder 31, the cutter blade 32 or the cutter holder 31 is provided with a driving hole 320 matched with the driving section 220, the driving hole 320 comprises a plurality of convex corners 321 extending vertically along the up-down direction, and the convex corners 321 are respectively in abutting fit with the convex edges 221. The motor shaft of the motor is connected with the rotating shaft 22, and the rotating shaft 22 drives the knife assembly 30 to rotate, so that food materials in the stirring cup 10 are whipped and crushed. Wherein the driving section 220 is provided with a stopping groove 229 above the driving hole 320, and the width of the stopping groove 229 in the up-down direction is greater than the thickness of the driving hole 320.

According to the stirring cup assembly 60, since the cutter assembly 30 is detachably arranged on the rotating shaft 22, when the stirring cup assembly 60 needs to be cleaned after being used, a user rotates the cutter assembly 30 along the deflection direction of the convex edge 221 to detach the cutter assembly 30, so that the stirring cup assembly 60 is thoroughly cleaned, dead angles which cannot be cleaned are avoided, and the conditions of bacteria breeding and peculiar smell generation are effectively avoided; meanwhile, since the driving section 220 includes the convex edge 221 deflected along the circumferential direction, the driving hole 320 includes the plurality of convex corners 321 extending vertically along the up-down direction, and the convex edge 221 plays a limiting role on the convex corners 321 in the rotation process of the knife assembly 30 along with the rotating shaft 22, thereby preventing the knife assembly 30 from being separated from the rotating shaft 22, and being convenient to install and detach; moreover, since the driving section 220 is provided with the retaining groove 229 above the driving hole 320, and the width of the retaining groove 229 in the up-down direction is greater than the thickness of the driving hole 320, so that during the process of the desizing, the knife rest 31 and/or the part of the blade 32 forming the driving hole 320 falls into the retaining groove 229 in the process of sliding toward the top end of the rotating shaft 22 (see fig. 6), and thus cannot slide out continuously along the extending direction of the flange 221, the flange 221 above the retaining groove 229 (the end of the rotating shaft 22 far away from the chassis 21) is staggered with the lobe 321 of the driving hole 320, and obviously, the flange 221 radially protrudes from the side between the adjacent 2 lobes 321, so that the part of the driving section 220 above the retaining groove 229 can play a limiting role on the knife rest 30, and the knife rest 30 is prevented from falling from the rotating shaft 22 during the desizing.

The deflection angle of the convex edge 221 is H in units of length of the driving section 220, and the value of H ranges from 1 to 3, and the unit of H is: degree/mm.

Preferably, the ratio of the width of the retaining groove 229 to the thickness of the drive hole 320 is between 1.1 and 1.5. By defining the ratio to be greater than or equal to 1.1, during desizing, as the portion of the blade holder 31 and/or the blade 32 forming the drive hole 320 falls into the retaining groove 229 during the sliding of the blade assembly 30 toward the top end of the spindle 22, the distance by which the convex edge 221 above the retaining groove 229 is offset from the convex edge 321 of the drive hole 320 can more reliably limit the blade assembly 30, thereby better avoiding the blade assembly 30 from falling off the spindle 22 during desizing; by defining the above ratio to be less than or equal to 1.5, the knife assembly 30 can be rotated in place on the spindle 22 more smoothly while the knife assembly 30 is rotatably mounted to the spindle 22, avoiding the precession effect from being affected by the retaining groove 229 being too wide. In some embodiments, the ratio of the width of the anti-backup slot 229 to the thickness of the drive aperture 320 may be 1.1, 1.2, 1.3, 1.4, 1.5, or some value between any two adjacent thereto.

The upper end of the retaining groove 229 is provided with a retaining surface 227, and the retaining surface 227 is perpendicular to the extending direction of the convex angle 321. In this way, by providing the retaining surface 227, the blade assembly 30 can be better prevented from falling off the rotating shaft 22 during slurry pouring.

The lower end of the retaining groove 229 is provided with a guide portion 228, and the radial dimension of the guide portion 228 gradually increases from top to bottom. In this manner, by providing the guide portion 228, the knife assembly 30 can be more smoothly mounted to the rotary shaft 22 under the guide of the guide portion 228. In some embodiments, the guide 228 may be configured as a ramp or a curved surface.

Referring to fig. 7, in this embodiment, the retaining groove 229 is provided with a retaining surface 227 and a guiding portion 228, the retaining surface 227 is disposed at an upper end of the retaining groove 229, the guiding portion 228 extends from an upper end to a lower end of the retaining groove 229, and a radial dimension of the guiding portion 228 gradually increases from top to bottom.

By limiting the deflection angle of the convex edge 221 and the height of the driving section 220, the convex edge 221 has a better limiting effect on the cutter assembly 30, the cutter assembly 30 cannot be separated from the rotating shaft 22 in the rotating process or the slurry pouring process, and the cutter assembly 30 is convenient to install and detach; by defining the thickness of the drive aperture 320, the drive aperture 320 is made to have greater strength and wear resistance at the mating location with the spindle 22, thereby increasing the life and stability of the knife assembly 30.

In some embodiments, the angle of deflection of the top end of the flange 221 relative to the bottom end may be 15 degrees, 25 degrees, 35 degrees, 45 degrees, 55 degrees, 65 degrees, 75 degrees, or some value therebetween; the height of the drive section 220 in the vertical direction may be 8 mm, 16 mm, 24 mm, 32 mm, 40 mm or some value between any two of the foregoing; the thickness T of the drive aperture 320 may be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, or some value between any two adjacent thereto.

In addition, the blade 32 and the fixed washer 33 jointly form the driving hole 320, so that the wear resistance of the blade 32 can be improved, and the service life and stability of the blade assembly 30 are improved.

The rotating shaft 22 further comprises a limiting section 2241 disposed above the driving section 220, and the tool rest 31 comprises a limiting hole 319 matched with the limiting section 2241. Through spacing hole 319 and spacing section 2241 cooperation, can be better spacing to the knife tackle spare 30, avoid the knife tackle spare 30 to take place to rock in the rotation. The spacing section 2241 is configured as a circular shaft, and the spacing hole 319 is configured as a circular hole, so that when the cutter assembly 30 is reversely assembled in the up-down direction, the first driving hole 320 cannot be matched with the driving section 220, and the rotating shaft 22 cannot drive the cutter assembly 30 to rotate at this time, so that the reverse assembly of the cutter assembly 30 can be avoided.
