Description

Technical Field

[0001] The utility model relates to the technical field of fruit puree machines, in particular to a knife mounting structure in a micro fruit puree machine and the micro fruit puree machine. Background Art

[0002] A fruit puree machine is a household appliance for crushing fruits into a puree. The fruit puree machine includes an output shaft for transmitting torque and a stirring blade connected to the output end of the output shaft. In the prior art, in order to facilitate the cleaning of the stirring blade, the stirring blade is detachably connected to the end of the output shaft. Generally, the output shaft and the stirring blade are threadedly connected. For example, the stirring blade assembly and the food processor disclosed in the patent with the authorization announcement number CN216602615U, in which the stirring blade assembly provided by the patent is threadedly connected to the barrier connected to the blade. When in use, the blade can only be driven by the blade to rotate in one direction. If it rotates in another direction, the threaded connection between the blade shaft and the blade will be loosened, and the blade will fall off the blade shaft, causing a series of problems. At the same time, since the blade is threadedly connected to the blade shaft, and the blade shaft is generally connected to the driving mechanism in a transmission manner, when the blade needs to be cleaned, the blade and the blade shaft are often separated by twisting the blade. This method of disassembling the blade by twisting the blade is relatively complicated to operate, and since the blade is relatively sharp, the process of rotating the blade is also dangerous. Utility Model Content

[0003] The utility model provides a knife-mounting structure in a miniature fruit puree machine, so as to solve the technical problems that the knife-mounting structure in the fruit puree machine in the prior art can only rotate in one direction and the disassembly process of the blade is relatively difficult.

[0004] The utility model also provides a micro fruit puree machine, in which a blade can rotate in forward and reverse directions, and the disassembly process of the blade is more convenient and safer.

[0005] In order to solve the above problems, the utility model provides a knife-mounting structure in a micro-fruit puree machine adopts the following technical solution:

[0006] A knife-loading structure in a miniature fruit puree machine, comprising:

[0007] A knife shaft and a connecting seat are arranged in sequence from top to bottom, and a knife blade is arranged on the connecting seat;

[0008] The connecting seat is provided with a plug-in slot with an opening facing upward, the inner side wall of the plug-in slot is provided with a first protrusion, the outer side wall of the knife shaft is provided with a second protrusion, the knife shaft is used to be inserted into the plug-in slot, and when the knife shaft rotates in the plug-in slot until the first protrusion contacts the second protrusion, the first protrusion and the second protrusion are blocked and matched in the circumferential direction of the knife shaft to transmit torque;

[0009] The second protrusion is provided with a limiting protrusion on both sides of the circumference, and the top of the limiting protrusion has a first stopping surface; the first protrusion is provided with a limiting recess or the first protrusion and the bottom of the plug-in groove are spaced from each other to form the limiting recess, and the top of the limiting recess has a second stopping surface. The limiting recess is for the limiting protrusion to rotate into, and the first stopping surface and the second stopping surface are matched in the up and down directions to prevent the knife shaft from moving upward relative to the connecting seat.

[0010] The above technical solution has the following beneficial effects: a first protrusion is provided in the plug-in slot, and a second protrusion is provided on the knife shaft. After the knife shaft is inserted into the plug-in slot, since the first protrusion and the second protrusion block each other in the circumferential direction of the knife shaft, the knife shaft can drive the blade to rotate in the forward and reverse directions, and the fruit can be crushed in two directions, which has a better crushing effect on the fruit. At the same time, after the limiting convex part on the second protrusion is transferred into the limiting concave part on the first protrusion, the first protrusion can limit the second protrusion from moving upward, so that when the knife shaft drives the blade to move in the up and down directions, the blade will not be separated from the knife shaft, and the knife shaft can drive the blade to move up and down, and the movement form of the blade is more diverse. It can move in the up and down directions while rotating and crushing to stir the fruit puree in the up and down directions, and the crushed fruit puree is more delicate and smooth.

[0011] Furthermore, the first stop surface and the second stop surface are both inclined surfaces arranged obliquely, and after the limiting protrusion is turned into the limiting concave portion, the first stop surface and the second stop surface are in contact with each other.

[0012] The beneficial effects of the above technical solution are: the first stop surface and the second stop surface are both inclined surfaces, which are easy to clean, and the first stop surface and the second stop surface fit each other, so that the lifting and lowering movements of the knife shaft and the blade are more synchronized.

[0013] Furthermore, the number of the first protrusions and the second protrusions is equal and there are at least two of each. The first protrusions and the second protrusions are alternately arranged in the circumferential direction of the knife shaft. In the circumferential direction of the knife shaft, the minimum spacing between any two adjacent first protrusions is greater than the maximum width of the second protrusion. The limiting recesses are provided on both sides of the circumference of the first protrusions.

[0014] Furthermore, the top of the first protrusion and the bottom of the second protrusion are both conical.

[0015] The beneficial effect of the above technical solution is that the top of the first protrusion is conical, and the bottom of the second protrusion is conical, which can play a guiding role and facilitate the insertion of the second protrusion between two adjacent first protrusions.

[0016] Furthermore, a first magnetic component is provided in the plug-in slot, and a second magnetic component is provided at the bottom end of the knife shaft. When the knife shaft is inserted into the plug-in slot, the first magnetic component and the second magnetic component are attracted to each other.

[0017] The beneficial effect of the above technical solution is: a first magnetic component is arranged in the plug-in slot, and a second magnetic component is arranged on the blade shaft, so that the blade shaft can be adsorbed on the connecting seat after being inserted into the plug-in slot, thereby preventing the blade from falling off the blade shaft.

[0018] Furthermore, a first accommodating groove is provided on the bottom of the plug-in groove, and the first magnetic component is buried in the first accommodating groove. A second accommodating groove is provided on the bottom end surface of the knife shaft, and the second magnetic component is buried in the second accommodating groove.

[0019] The beneficial effect of the above technical solution is that the first magnetic member and the second magnetic member are respectively buried in the first accommodating groove and the second accommodating groove without occupying external space.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0032] The following is one embodiment of the knife-mounting structure in a micro-fruit puree machine provided by the utility model:

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a knife-mounting structure in a micro-fruit puree machine comprises a knife shaft 1 and a connecting seat 3 arranged in sequence from top to bottom, and a blade 2 is connected to the connecting seat 3. The connecting seat 3 is tapered, and is provided with a plug-in slot 12 with an opening facing upward, and the inner side wall of the plug-in slot 12 is provided with three evenly arranged first protrusions 7, and the first protrusion 7 comprises a first stopper 9 and a first vertical ridge 8 arranged in sequence from top to bottom, and the first vertical ridge 8 extends to the bottom surface of the plug-in slot 12 and is connected to the bottom surface of the plug-in slot 12. The first stopper 9 is wider than the first vertical ridge 8, and the top of the first stopper 9 is tapered, and the left and right sides of the first stopper 9 near the first vertical ridge 8 are both provided with outwardly protruding inclined surfaces, and the inclined surfaces form a first stopper surface 901, and the two first stopper surfaces 901 are separated from each other from bottom to top, and a limiting recess in the first protrusion 7 is formed between the first stopper surface 901 and the first vertical ridge 8. A first accommodating groove 11 is provided on the bottom surface of the plug-in groove 12, and a first magnetic component is buried in the first accommodating groove 11. The first magnetic component is fixed in the first accommodating groove 11 by an adhesive, or is fixed in the first accommodating groove 11 by an interference fit with the first accommodating groove 11 to prevent the first magnetic component from escaping from the first accommodating groove 11.

[0034] The outer wall at the bottom of the blade shaft 1 is provided with three second protrusions 4 evenly arranged in the circumferential direction of the blade shaft 1. The second protrusion 4 includes a second vertical edge 5 and a second stopper 6 arranged in sequence from top to bottom. The second stopper 6 is wider than the second vertical edge 5. The bottom end of the second stopper 6 is inverted cone shape. The left and right sides of the second stopper 6 near the second vertical edge 5 both have inclined surfaces protruding outwards. The inclined surfaces form second stopper surfaces 601. The two second stopper surfaces 601 are away from each other from top to bottom. The part of the second stopper 6 protruding from the second vertical edge 5 forms a limiting convex part in the second protrusion. When the blade shaft 1 is inserted into the plug-in slot 12 and rotated relative to the blade 2 until the first protrusion 7 and the second protrusion 4 contact each other, the limiting convex part turns into the limiting concave part, and the first stopper surface 901 and the second stopper surface 601 fit each other. A second accommodating groove 10 is provided on the bottom end surface of the knife shaft 1, and a second magnetic component is embedded in the second accommodating groove 10. The second magnetic component is fixed in the second accommodating groove 10 by an adhesive, or is fixed in the second accommodating groove 10 by an interference fit with the second accommodating groove 10 to prevent the second magnetic component from escaping from the second accommodating groove 10.

[0035] When the utility model is in use, the knife shaft 1 is inserted into the plug-in slot 12, and the knife shaft 1 and the blade 2 are magnetically attracted together by the first magnetic part and the second magnetic part, so as to prevent the knife shaft 1 from falling off directly from the plug-in slot 12. Then, the knife shaft 1 and the blade 2 are placed in the crushing chamber of the micro-fruit puree machine, and the start button of the micro-fruit puree machine is pressed, the knife shaft 1 starts to rotate, and the blade 2 rotates relative to the knife shaft 1 under the obstruction of the fruit in the crushing chamber. The knife shaft 1 and the blade 2 rotate relative to each other until the first protrusion 7 contacts the second protrusion 4. At this time, the first stop surface 901 and the second stop surface 601 fit each other, and the knife shaft 1 can drive the blade 2 to rotate, and the second stop block 6 and the first stop block 9 are buckled and stopped in the up and down directions, and the blade 2 will not detach from the knife shaft 1 in the up and down directions. The knife shaft 1 drives the blade 2 to rotate and lift in the crushing chamber to crush the fruit into puree. When the blade 2 needs to be cleaned after use, the blade 2 only needs to be taken out of the cutter shaft 1 and the blade 2 from the crushing chamber, and then the blade 2 is rotated at a certain angle so that the first protrusion 7 and the second protrusion 4 are away from each other, and the blade 2 can be removed from the cutter shaft 1 for cleaning.

[0036] The utility model can realize that the knife shaft drives the blade to rotate in the forward and reverse directions to crush the fruit, and has the advantages of simple structure, convenient disassembly and more convenient use.

[0037] In this embodiment, the first protrusion includes a first stop block and a first vertical edge, the second protrusion includes a second stop block and a second vertical edge, and the first stop block has an inclined first stop surface, and the second stop block has an inclined second stop surface. The first stop surface and the second stop surface are fitted together to realize the stopping cooperation between the knife shaft and the blade in the circumferential direction of the knife shaft and the anti-slip cooperation between the knife shaft and the blade in the up and down directions. In other embodiments, the first protrusion is T-shaped and the second protrusion is in an inverted T-shape. At this time, the first stop surface in the first protrusion is a plane, and the second stop surface in the second protrusion is a plane. The first T-shaped first protrusion and the inverted T-shaped second protrusion are interlocked with each other to realize the stopping cooperation between the knife shaft and the blade in the circumferential direction of the knife shaft and the anti-slip cooperation in the up and down directions. At this time, the interlocking structure of the first protrusion and the second protrusion is as follows: Figure 6 shown.

[0038] In this embodiment, three second protrusions are evenly distributed on the knife shaft, and three first protrusions are evenly distributed in the connecting seat. In other embodiments, two second protrusions are evenly distributed on the knife shaft, and two first protrusions are evenly distributed in the connecting seat.

[0039] The utility model also provides a micro fruit puree machine, in which the knife mounting structure of the micro fruit puree machine in the above embodiment is installed.
