[0031] See also Figures 1 to 4 The present invention provides a multifunctional blending machine, comprising: a main unit 100, wherein the main unit 100 has a first placement plane 110 and a second placement plane 120 perpendicular to each other; the main unit 100 is rotatably provided with a main shaft 200 perpendicular to the first placement plane 110; the first placement plane 110 is placed on a desktop so that the main shaft 200 is arranged vertically; the second placement plane 120 is placed on a desktop so that the main shaft 200 is arranged horizontally; a first blending mechanism 300, detachably connected to the main unit 100, the first blending mechanism 300 including a vertically arranged first container 310 and a stirring blade 320 rotatably arranged in the first container 310, the stirring blade 320 is transmission-connected to the vertically arranged main shaft 200; a second stirring mechanism 400 is detachably connected to the main unit 100, and is transmission-connected to the horizontally arranged main shaft 200, the second stirring mechanism 400 includes a horizontally placed second container 410 and a stirring member 420 rotatably arranged in the second container 410, the stirring member 420 is transmission-connected to the horizontally arranged main shaft 200, and the second container 410 is respectively provided with a feed port 411 and a discharge port 412 communicated with its inner cavity.
[0032] The user places the first placement plane 110 or the second placement plane 120 of the main unit 100 on the desktop according to usage needs. At this time, the main shaft 200 is in a vertical or horizontal state. The first stirring mechanism 300 is assembled to realize the function of rotating the stirring blade 320 around the vertical main shaft 200. The second stirring mechanism 400 is assembled to realize the function of rotating the stirring member 420 around the horizontal main shaft 200. In this way, different types of stirring mechanisms can be replaced to expand the usage functions. Only one main unit 100 is needed to match multiple types of stirring mechanisms, reducing the required storage space and reducing the usage cost.
[0033] See also Figure 6 and Figure 7In some embodiments of the present invention, the main unit 100 is provided with a mounting base 130 on the outer periphery of the main shaft 200. The mounting base 130 is provided with at least two first rotating clamps distributed around the circumference of the main shaft 200. The first container 310 and the second container 410 are both provided with second rotating clamps corresponding to the first rotating clamps. It can be understood that the use of the first rotating clamps in conjunction with the second rotating clamps can quickly achieve the installation and removal of the first stirring mechanism 300 or the second stirring mechanism 400, and it is not easy for the first stirring mechanism 300 or the second stirring mechanism 400 to fall off from the main unit 100 due to accidental touch. Of course, in other embodiments, the first stirring mechanism 300 and the second stirring mechanism 400 can also be detachably mounted on the main unit 100 by magnetic attraction.
[0034] See also Figure 4 、 Figure 6 and Figure 7 In some embodiments of the present invention, the mounting seat 130 has an annular wall plate coaxial with the main shaft 200, the first rotating clamping member is a rotating slot 510 formed on the inner wall of the annular wall plate, and the second rotating clamping member is a rotating buckle portion 520 matching the rotating slot 510. The mounting seat 130 is movably provided with an anti-escape member 600, and the anti-escape member 600 can be moved to the entrance of the rotating slot 510 to prevent the rotating buckle portion 520 from leaving the rotating slot 510, or the anti-escape member 600 can be moved away from the rotating slot 510 to allow the rotating buckle portion 520 to disengage from the rotating slot 510. It can be understood that before installing the first stirring mechanism 300 or the second stirring mechanism 400, the anti-escape member 600 is first moved away from the rotation slot 510, so that the rotation buckle portion 520 on the first container 310 or the second container 410 can enter from the entrance of the rotation slot 510. After the first container 310 or the second container 410 is rotated into place, the anti-escape member 600 moves to the entrance of the rotation slot 510 to prevent the rotation buckle portion 520 from leaving the rotation slot 510, thereby locking the first stirring mechanism 300 or the second stirring mechanism 400 on the main unit 100 to ensure that the stirring work proceeds normally.
[0035] See also Figure 6In some embodiments of the present invention, the mounting seat 130 is provided with a guide slot 131 extending perpendicularly to the direction of movement of the rotating latch portion 520. The anti-escape member 600 is telescopically disposed in the guide slot 131. The anti-escape member 600 is connected to an elastic member 610 that drives it to the entrance of the rotating latch portion 510. The anti-escape member 600 is provided with a pressing portion 620 extending beyond the mounting seat 130. The pressing portion 620 is movable in a direction that compresses the elastic member 610 to move the anti-escape member 600 away from the rotating latch portion 510. It should be noted that when the rotating latch portion 520 moves outward from the entrance of the rotating latch portion 510, it is blocked by the anti-escape member 600. Because the direction of the guide slot 131 is perpendicular to the direction of movement of the rotating latch portion 520, the anti-escape member 600, under the action of the elastic member 610, will not retract from the guide slot 131 due to the force applied by the rotating latch portion 520. When the user wants to disassemble the first stirring mechanism 300 or the second stirring mechanism 400, force is applied to the pressing portion 620 to make the anti-detachment member 600 leave the rotating slot 510. At this time, the elastic member 610 is in a compressed state. When the rotating buckle portion 520 enters the rotating slot 510 and is in place, the pressing portion 620 is released to drive the anti-detachment member 600 to reset.
[0036] See also Figure 3 In some embodiments of the present invention, the first container 310 is used for kneading dough. The first container 310 is bowl-shaped or cylindrical. A first rotating shaft 330 is rotatably provided at the center position of the bottom of the first container 310. One end of the first rotating shaft 330 extends from the first container 310 to connect to the main shaft 200, and the other end of the first rotating shaft 330 extends into the first container 310 to connect to the stirring blade 320. The stirring blade 320 extends from the outer wall of the first rotating shaft 330 toward the inner wall of the first container 310. The stirring blade 320 has a first stirring blade 321 extending to the vicinity of the bottom wall of the first container 310 and a second stirring blade 322 set in a direction away from the bottom wall of the first container 310. It can be understood that when the first placement plane 110 is placed on the table so that the main shaft 200 is vertically upward, the main shaft 200 drives the first rotating shaft 330 and the stirring blade 320 to rotate, and the stirring blade 320, the first stirring blade 321 and the second stirring blade 322 work together to achieve the function of kneading the dough, further broadening the use function of the stirring machine.
[0037] In some embodiments of the present invention, to be suitable for mincing meat, the first container 310 is bowl-shaped or cylindrical, with a first rotating shaft 330 rotatably disposed at the center of the bottom of the first container 310. One end of the first rotating shaft 330 extends from the first container 310 to connect to the main shaft 200, and the other end of the first rotating shaft 330 extends into the first container 310. The stirring blade 320 includes a plurality of meat-mincing blades radially distributed around the outer periphery of the first rotating shaft 330. Of course, in other embodiments, depending on the desired item being stirred, the first container 310 and stirring blade 320 may be replaced with other structural forms.
[0038] See also Figure 4 In some embodiments of the present invention, the stirring element 420 is a screw propeller coaxial with the main shaft 200. The feed inlet 411 is connected to the side of the starting end of the screw propeller. The second container 410 is provided with a filter 430 surrounding the outside of the screw propeller. The discharge port 412 includes a juice outlet connected to the outside of the filter 430 and a residue outlet connected to the end of the screw propeller. The second stirring mechanism 400 and the main unit 100 of the above structure are combined to form a horizontally arranged juicer. The user places the food to be juiced into the second container 410 through the feed inlet 411. The food is ground by the screw propeller to form juice, which passes through the filter 430 and is discharged from the juice outlet. The food residue moves to the end of the screw propeller and is discharged from the residue outlet. The second stirring mechanism 400 of this structure, in conjunction with the first stirring mechanism 300 for kneading dough, realizes the dual functions of a juicer and a dough mixer, which is very practical.
[0039] See also Figure 5 In some embodiments of the present invention, the second container 410 has a discharge channel that is open and away from the main shaft 200, and the side wall of the second container 410 is provided with a feed pipe 440 connected to the discharge channel. The stirring member 420 is a cutting blade close to the inner wall of the discharge channel, and the main shaft 200 drives the cutting blade to intermittently pass through the junction of the feed pipe 440 and the second container 410. In this embodiment, the discharge channel is cylindrical, and the main shaft 200 drives a circular sleeve located on the inner circumference of the discharge channel to rotate. The cutting blade is arranged on the wall of the circular sleeve, and the cutting blade is provided with a plurality of through holes for food to pass through. After radish, potato and other food enter the feed pipe 440, one end of the radish, potato and other food rests on the outer surface of the circular sleeve, and the cutting blade can cut the food when it intermittently passes through the junction of the feed pipe 440 and the second container 410. The cut food enters the interior of the circular sleeve and is discharged from the opening of the discharge channel, thereby cutting the food into strips.
[0040] See also Figure 2 、 Figure 5 In some embodiments of the present invention, a plurality of suction cups 700 are spaced apart on the first placement surface 110. When the second placement surface 120 is placed on a table, the suction cups 700 can be fixed to a wall by suction. It should be noted that when the main shaft 200 is arranged horizontally, the main shaft 200 drives the stirring blades 320 or the stirring member 420 to rotate, generating significant vibrations that affect the stability of the main unit 100. Fixing the suction cups 700 to the wall can reduce this vibration.
[0041] See also Figure 2 In some embodiments of the present invention, in order to achieve a compact structure, the length dimension of the first placement plane 110 is greater than the length dimension of the second placement plane 120, and the host 100 is provided with a default portion 140 for placing the material receiving container 800 at a position corresponding to the second placement plane 120, which is suitable for use when the second stirring mechanism 400 is used as a juicer.
[0042] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0043] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
