Description

Technical Field

[0001] The utility model relates to the technical field of fruit puree processing mechanisms, in particular to a knife mounting structure and a 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 often detachably connected to the end of the output shaft. Generally, the output shaft and the stirring blade are threadedly connected, and the blade shaft is generally connected to a driving mechanism. When the stirring blade needs to be cleaned, the stirring blade and the blade shaft are often separated by holding the blade shaft and twisting the stirring blade. This method of disassembling by twisting the stirring blade is relatively complicated to operate. Since the blade is relatively sharp, it may also cause certain dangers during the rotation of the blade. Utility Model Content

[0003] The utility model provides a knife installation structure to solve the technical problem that the disassembly process of the stirring knife in the micro-fruit puree machine in the prior art is relatively dangerous.

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

[0005] In order to solve the above problems, the utility model provides a knife installation structure adopting the following technical solutions:

[0006] A knife mounting structure, comprising:

[0007] The blade shaft and the mixing blade are arranged from top to bottom, the top of the mixing blade is provided with a connecting seat, the connecting seat is provided with a plug-in slot for inserting the blade shaft, and the blade shaft and the connecting seat are plugged together in a non-rotatable manner;

[0008] The side wall of the connecting seat is provided with a mounting hole extending in the radial direction of the connecting seat, and a limiting ball is provided in the mounting hole;

[0009] The knife shaft is provided with a limiting notch corresponding to the position of the mounting hole, and the groove depth of the limiting notch is smaller than the diameter of the limiting ball;

[0010] The outer anti-detachment connection of the connecting seat is provided with a clamping assembly, which has a movable clamping part. The clamping part is used to move to the mounting hole after the knife shaft is inserted into the connecting seat, and press the limiting ball into the limiting groove. The clamping part is also used to move to the side of the mounting hole when the knife shaft and the mixing knife are disassembled to make the limiting ball disengage from the limiting groove.

[0011] The beneficial effect of the above technical solution is that the state of the limiting ball is controlled by moving the clamping part. When assembling the knife shaft and the mixing knife, it is only necessary to move the clamping part to the mounting hole, press the limiting ball into the limiting groove, and make the limiting ball stuck between the knife shaft and the connecting seat, so that the knife shaft and the mixing knife can be assembled. When the knife shaft and the mixing knife need to be disassembled, it is only necessary to move the clamping part to the side of the mounting hole to make the limiting ball disengage from the limiting groove, and then the mixing knife can be removed from the knife shaft. The disassembly method is simple, and there is no need to screw the mixing knife, and the disassembly process is safer.

[0012] Furthermore, the clamping assembly includes a sleeve and a spring which are sequentially sleeved on the connecting seat in the up-down direction, the clamping portion is arranged on the inner wall of the sleeve, and the spring can be extended and retracted in the up-down direction. The spring is used to apply elastic force to the sleeve to keep the sleeve in a state where the clamping portion is in the mounting hole, and is stretched or compressed when subjected to external force to drive the sleeve to move so that the clamping portion leaves the mounting hole.

[0013] The beneficial effects of the above technical solution are: the clamping assembly includes a sleeve and a spring, and the clamping part is arranged on the sleeve. When in use, the compression spring can keep the clamping part on the sleeve in a state of being pressed at the mounting hole when not subjected to external force, so that the limiting ball is stuck between the knife shaft and the connecting seat, thereby realizing the connection between the knife shaft and the mixing knife. When the mixing knife needs to be removed from the knife shaft, it is only necessary to move the sleeve to stretch or compress the spring so that the clamping part on the sleeve can leave the mounting hole. At this time, the limiting ball in the mounting hole can be disengaged from the limiting groove on the knife shaft, and the mixing knife can be removed from the knife shaft. The disassembly method is simple.

[0014] Furthermore, a protruding annular clamping section is provided on the inner wall of the sleeve, and the annular clamping section forms the clamping portion. The protruding annular clamping section forms a gap between the inner wall of the sleeve and the outer wall of the connecting seat, and the gap forms an accommodating space. The accommodating space is used for allowing the limiting ball to enter when the annular clamping section moves to the side of the mounting hole.

[0015] The beneficial effect of the above technical solution is: a protruding annular clamping section is provided on the inner side wall of the sleeve as a clamping portion, so that the protruding annular clamping section forms an accommodating space between the connecting seat and the inner side wall of the sleeve, so that after the clamping section leaves the mounting hole, the limiting ball will not completely fall out of the mounting hole, but will be inserted into the accommodating space under the obstruction of the sleeve, thereby avoiding the limiting ball from completely falling out when disassembling the mixing knife, which makes the reassembly process complicated.

[0016] Furthermore, the annular pressing section is connected to the accommodating space via an inclined surface, and the inclined surface forms a pushing inclined surface for pushing the limiting ball into the limiting groove during the movement of the sleeve in the up-down direction.

[0017] The beneficial effect of the above technical solution is that when assembling the blade shaft and the mixing blade, it is only necessary to move the sleeve so that the pushing inclined surface pushes the limiting ball, and the limiting ball can be pressed into the limiting groove on the blade shaft, and the connection between the accommodating space and the clamping part is more coherent, without affecting the movement of the sleeve.

[0018] Furthermore, an annular limiting step is provided on one side of the mounting hole facing the plug-in slot, and the limiting step is used to limit the limiting ball from falling into the plug-in slot.

[0019] The beneficial effect of the above technical solution is that the setting of the limiting step can prevent the limiting ball from falling into the plug-in slot when the blade shaft is not inserted into the plug-in slot, thereby preventing the limiting ball from falling off and hindering the assembly of the mixing blade and the blade shaft.

[0020] Furthermore, a stopper is provided on the top of the connecting seat, and the clamping assembly is provided between the stopper and the stirring blade. The stopper is used to limit the upward movement of the clamping assembly so that the clamping assembly is prevented from being disconnected and connected to the outside of the connecting seat.

[0021] The beneficial effect of the above technical solution is that a stopper is provided on the top of the connecting seat to limit the movement of the clamping assembly in the up and down directions, avoid the clamping assembly from constantly shaking on the connecting seat, and prevent the clamping assembly from falling off the connecting seat.

[0022] Furthermore, an annular connecting groove is provided on the outer side wall of the top of the connecting seat, an annular elastic retaining ring with an opening is provided in the connecting groove, the annular elastic retaining ring protrudes from the connecting seat, and the annular elastic retaining ring forms the stopper.

[0023] The beneficial effect of the above technical solution is that the stopper is an annular elastic retaining ring, and a detachable connection can be achieved between the annular elastic retaining ring and the connecting groove, so that during assembly, the sleeve can be installed first, and then the stopper can be installed, which will not affect the installation of the sleeve.

[0024] Furthermore, the cross section of the limiting slot is in an arc shape, and the limiting slot extends along the circumference of the knife shaft.

[0025] The beneficial effects of the above technical solution are: the cross-section of the limiting groove is arc-shaped, which is more compatible with the shape of the ball, and the limiting groove extends along the circumference of the knife shaft. The limiting groove has a certain length, so that the limiting ball is easier to align with the limiting groove during assembly, making it easier to insert the limiting ball into the limiting groove.

[0026] Furthermore, the knife shaft and the connecting seat are anti-rotationally assembled by means of a limiting protrusion and a limiting groove that are adapted to fit together.

[0027] The beneficial effects of the above technical solution are: the knife shaft and the connecting seat are anti-rotationally assembled by the limiting protrusion and the limiting groove, the structure is simple, the knife shaft can drive the mixing knife to rotate in both positive and negative directions, the rotation state of the mixing knife is more diverse, and the fruit crushing effect is better.

[0028] The utility model provides a miniature fruit puree machine adopts the following technical scheme:

[0029] A miniature fruit puree machine comprises the above-mentioned knife mounting structure.

[0030] The beneficial effect of the above technical solution is that: using the micro-fruit puree machine with the knife-mounting structure, the stirring knife therein is safe and convenient to disassemble, and is easy to clean frequently. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] 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.

[0042] The following is an embodiment 1 of a knife mounting structure provided by the utility model:

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a knife installation structure includes a knife shaft 1 and a mixing knife 2. A connection seat 3 is provided on the top of the mixing knife 2. A plug-in slot 304 with an opening facing upward is provided on the connection seat 3. The plug-in slot 304 is used for inserting the knife shaft 1. Three limiting protrusions 302 are arranged evenly around the circumference of the connection seat 3 on the inner side wall of the plug-in slot 304. Three limiting grooves 101 are arranged evenly around the circumference of the knife shaft 1 on the outer side wall of the knife shaft 1. The limiting protrusions 302 are adapted to be inserted into the limiting grooves 101 along the up-down direction, so that the knife shaft 1 is assembled in the connection seat 3 without rotating.

[0044] The connection seat 3 is provided with a clamping assembly outside, and the clamping assembly includes a sleeve 5 and a spring 4 arranged in sequence from top to bottom. An annular connection groove 303 is provided on the outer side wall of the top of the connection seat 3, and an annular elastic retaining ring 7 with an opening is provided in the connection groove 303. The annular elastic retaining ring 7 protrudes from the connection seat 3, as shown in FIG. Figure 5 As shown, a protruding annular stop step 503 is provided at the top of the inner wall of the sleeve 5, and an annular elastic retaining ring 7 is disposed above the annular stop step 503 to limit the movement of the sleeve 5 and the spring 4 in the up and down directions, thereby realizing anti-slip cooperation between the clamping assembly and the connecting seat 3.

[0045] A mounting hole 301 extending radially along the connecting seat 3 is provided on the side wall of the connecting seat 3, and an annular limiting step is provided on the side of the mounting hole 301 facing the plug-in slot 304. A limiting ball 6 is provided in the mounting hole 301, and the diameter of the limiting ball 6 is larger than the hole depth of the mounting hole 301. The limiting step is used to limit the movement of the limiting ball 6 toward the plug-in slot 304, so that the limiting ball 6 can extend into the plug-in slot 304 but will not completely fall into the plug-in slot 304. A circle of protruding annular clamping section 501 is provided at the bottom of the inner wall of the above-mentioned sleeve 5. The annular clamping section 501 is the clamping part on the sleeve 5. The annular clamping section 501 forms a gap between the inner wall of the sleeve 5 and the outer wall of the connecting seat 3. The gap forms an accommodating space 8. The width of the accommodating space 8 is smaller than the diameter of the limiting ball 6. The accommodating space 8 and the annular clamping section 501 are connected by an inclined surface, which is a push inclined surface 502.

[0046] A limiting notch 102 is provided on the outer wall of the blade shaft 1. The cross section of the limiting notch 102 is in an arc shape. The limiting notch 102 extends along the circumference of the blade shaft 1. The groove depth of the limiting notch 102 is smaller than the diameter of the limiting ball 6. After the blade shaft 1 is inserted into the insertion groove 304, the limiting notch 102 matches the height position of the mounting hole 301.

[0047] When the utility model is in use, the clamping assembly is first assembled on the connecting seat 3, the spring 4 and the sleeve 5 are sequentially sleeved on the outer side of the connecting seat 3, and then the annular elastic retaining ring 7 is inserted into the connecting groove 303, so that the annular elastic retaining ring 7 is blocked on the annular stopping step 503 in the sleeve 5, the sleeve 5 is pushed downward, the spring 4 is compressed, so that the mounting hole 301 on the connecting seat 3 is exposed, the limiting ball 6 is placed in the mounting hole 301, the sleeve 5 is released, the spring 4 recovers its deformation, and pushes the sleeve 5 to move upward, so that the annular clamping section 501 moves to the mounting hole 301, and pushes the limiting ball 6 to move toward the plug-in groove 304, so that the structure on the connecting seat 3 is assembled.

[0048] When assembling the blade shaft 1 and the stirring blade 2, push the sleeve 5 downward to make the annular clamping section 501 leave the mounting hole 301, insert the blade shaft 1 into the plug-in groove 304, and the limiting protrusion 302 is adapted to be plugged into the limiting groove 101. During the process of inserting the blade shaft 1 into the plug-in groove 304, the side wall of the blade shaft 1 pushes the limiting ball 6 out of the plug-in groove 304, and the limiting ball 6 is inserted into the accommodating space 8 until the blade shaft 1 is completely inserted into the plug-in groove 304, and the limiting groove 102 corresponds to the position of the mounting hole 301. At this time, release the sleeve 5, and the spring 4 pushes the sleeve 5 to move upward, and the pushing inclined surface 502 pushes the limiting ball 6, so that the limiting ball 6 is inserted into the limiting groove 102. The sleeve 5 is kept in a state where the annular pressing section 501 covers the mounting hole 301 under the action of the spring 4, so that the limiting ball 6 is kept stuck between the limiting notch 102 and the mounting hole 301, thereby connecting the connection seat 3 and the blade shaft 1 together. During the mixing process, the blade shaft 1 can drive the mixing blade 2 to move in the up and down directions. When removing the mixing blade 2, it is only necessary to push the sleeve 5 downward to make the annular pressing section 501 leave the mounting hole 301. In the process of extracting the blade shaft 1 from the plug-in slot 304, the limiting ball 6 will break away from the limiting notch 102 and move into the accommodating space 8, so that the blade shaft 1 can be separated from the connection seat 3, so that the mixing blade 2 can be removed from the blade shaft 1.

[0049] In a knife installation structure provided by the utility model, the stirring knife and the knife shaft can be easily assembled and disassembled, and the stirring knife can be disassembled from the knife shaft without twisting the stirring knife, so the disassembly process is safer.

[0050] The following is a second embodiment of a knife mounting structure provided by the utility model:

[0051] like Figure 6 and Figure 7 As shown, in this embodiment, the pressing assembly only includes the spring 4, and the inner side wall of the spring 4 is the pressing part in the pressing assembly. At this time, when the blade shaft 1 and the mixing blade 2 are assembled, the spring 4 is used to press the limiting ball 6, and the limiting ball 6 is pressed into the limiting notch 102 on the blade shaft 1. When the blade shaft 1 and the mixing blade 2 are disassembled, the spring 4 is pushed to compress the spring 4, so that the limiting ball 6 is exposed, and the limiting ball 6 is taken out from the mounting hole 301, so that the blade shaft 1 can be removed from the connecting seat 3.

[0052] The following is a third embodiment of a knife mounting structure provided by the utility model:

[0053] In this embodiment, the limiting protrusion 302 is arranged on the outer wall of the blade shaft 1, the limiting groove 101 is arranged on the inner wall of the plug-in groove 304 on the connecting seat 3, and other structures are consistent with those in Example 1.

[0054] The following is a fourth embodiment of a knife-mounting structure provided by the utility model:

[0055] In this embodiment, the inner side wall of the sleeve 5 is not provided with an annular clamping section 501, nor is the annular stopping step 503. At this time, the annular elastic retaining ring 7 is pressed on the top surface of the sleeve 5 to stop the sleeve 5. The inner side wall of the sleeve 5 is the clamping part in the clamping assembly. When assembling the mixing knife 2, the inner side wall of the sleeve 5 is used to press the limiting ball 6 into the limiting groove 102. When disassembling the mixing knife 2, the entire sleeve 5 is moved away from the mounting hole 301 to expose the mounting hole 301. The limiting ball 6 can be separated from the limiting groove 102, and the knife shaft 1 can be separated from the connecting seat 3.

[0056] The utility model also provides a miniature fruit puree machine. The following is an embodiment 1 of the miniature fruit puree machine provided by the utility model:
