For those skilled in the art, the specific meaning of these terms in the present application can be understood according to the specific situation.

[0030] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and are not used to limit the present application.

[0031] Referring to Figure 1 and Figure 2 The embodiment of the present application provides a wall breaking machine, which comprises a shell 1, a rotating shaft 2, a stirring knife 3, a stirring hammer 4 and a grinding disc 5, the rotating shaft 2 is rotatably connected in the interior of the shell 1; the stirring knife 3 is connected with the rotating shaft 2; the stirring hammer 4 is connected with the rotating shaft 2 and located below the stirring knife 3; the grinding disc 5 is arranged in the shell 1, and the stirring hammer 4 is located in the grinding disc 5 and is arranged in a spaced manner with the grinding disc 5.

[0032] In practical applications, the cell wall breaking machine usually further comprises a driving base, the shell 1 is installed on the driving base, the rotating shaft 2 is connected with an output shaft of the driving base, and the driving base is used to drive the rotating shaft 2 to rotate; the rotating shaft 2 is sequentially connected with the stirring blade 3 and the stirring hammer 4 from top to bottom, and the stirring hammer 4 is arranged in the grinding disc 5 and spaced from the grinding disc 5; the shell 1 is provided with a feeding port 17, food is put into from the feeding port 17, the rotating shaft 2 rotates at high speed, drives the stirring blade 3 and the stirring hammer 4 to rotate together, the stirring blade 3 first cuts the food into pieces, and then the cut food falls between the stirring hammer 4 and the grinding disc 5, and is ground by the stirring hammer 4 and the grinding disc 5 to form a fine fluid, so as to realize breaking of the cell wall of the food to meet the use demand of the user.

[0033] Compared with the prior art, the application combines the stirring blade 3, the stirring hammer 4 and the grinding disc 5, the stirring blade 3 first cuts the food into pieces, and then the stirring hammer 4 and the grinding disc 5 are finely ground, which combines the advantages of two different breaking methods, can provide more extensive functions and better use experience. This design can realize efficient processing of various food materials in the same device, meet the needs of users in different scenarios. And the stirring hammer 4 and the grinding disc 5 are spaced, so that the stirring hammer 4 does not contact the grinding disc 5 during grinding, thereby avoiding surface wear and tear, avoiding residue dropping of the grinding disc 5, ensuring the safety of the food, improving the use experience of the user and the health of the diet.

[0034] Again refer to Figure 2 , the stirring hammer 4 comprises a connecting part 41 and a hammering part 42, the connecting part 41 is rotationally connected to the rotating shaft 2 in the circumferential direction, the hammering part 42 is connected to one end of the connecting part 41 close to the grinding disc 5, and the hammering part 42 is spaced from the grinding disc 5; or the connecting part 41 is connected with the rotating shaft 2, and the hammering part 42 is rotationally connected to one end of the connecting part 41 close to the grinding disc 5 in the circumferential direction.

[0035] In an embodiment, the connecting part 41 is rotationally connected with the rotating shaft 2, and the rotating shaft 2 is provided with a mounting piece 7, the mounting piece 7 is provided with a plug hole, the connecting part 41 extends into the plug hole and rotationally cooperates with the plug hole, that is, the connecting part 41 can rotate within a certain angle range relative to the rotating shaft 2 in the circumferential direction.

[0036] In practical application, the stirring hammer 4 may encounter large or hard food pieces during grinding. In order to avoid the stirring hammer 4 from being stuck and affecting the grinding work, the connecting part 41 is rotationally connected with the rotating shaft 2. When the rotating shaft 2 rotates, the rotating shaft 2 drives the stirring hammer 4 to rotate. When the stirring hammer 4 collides with the large food pieces, the connecting part 41 rotates relative to the rotating shaft 2 under the action of the collision force, so that the interval between the stirring hammer 4 and the grinding disc 5 is increased, the food pieces can pass through more conveniently, the stirring hammer 4 is prevented from being stuck, and the device is suitable for grinding food of different sizes and the practicability of the device is improved.

[0037] It should be noted that the rotating direction of the connecting part 41 is opposite to the rotating direction of the rotating shaft 2. In other embodiments, the connecting part 41 can be fixedly connected with the rotating shaft 2, and the hammering part 42 is rotationally connected with the connecting part 41. When the hammering part 42 collides with the large food pieces, the hammering part 42 rotates relative to the connecting part 41, so that the interval between the hammering part 42 and the grinding disc 5 is increased, and the similar effect as described above is achieved.

[0038] Referring to Figure 2 and Figure 3 The wall breaking machine further comprises a screen 6 arranged in the shell 1 and separating the shell 1 into an upper cavity 11 and a lower cavity 12 along the axial direction. The stirring blade 3 is located in the upper cavity 11, and the stirring hammer 4 and the grinding disc 5 are located in the lower cavity 12. The screen 6 is provided with a first screen hole 61 and a second screen hole 62 which communicate the upper cavity 11 and the lower cavity 12. The first screen hole 61 is arranged relative to the inside of the grinding disc 5, and the second screen hole 62 is arranged relative to the outside of the grinding disc 5. The bottom of the grinding disc 5 is provided with a flow hole 51 which communicates the inside and the outside of the grinding disc 5.

[0039] In practical application, the shell 1 is provided with a feeding port 17 which communicates with the upper cavity 11. Food enters the upper cavity 11 from the feeding port 17 and is preliminarily cut by the stirring blade 3, so that food particles of different sizes fall into the lower cavity 12 from the first screen hole 61 and the second screen hole 62. The food falling from the first screen hole 61 can enter the grinding disc 5 and be finely ground by the stirring hammer 4 and the grinding disc 5 to form fine fluid which flows out of the grinding disc 5 from the flow hole 51. The food falling from the second screen hole 62 falls outside the grinding disc 5. However, when the rotating shaft 2 rotates at high speed, the stirring blade 3 rotates at high speed to generate strong vortex flow in the upper cavity 11, so that the pressure outside the grinding disc 5 is greater than the pressure in the upper cavity 11. Under the action of the pressure difference, the food outside the grinding disc 5 returns to the upper cavity 11 from the second screen hole 62, is repeatedly cut by the stirring blade 3, and is ground by the stirring hammer 4 and the grinding disc 5 again, so that the food is circularly ground and the fineness of the wall breaking of the food is improved.

[0040] Referring to Figure 3 and Figure 4The first sieve hole 61 has a larger diameter than the second sieve hole 62, and the second sieve hole 62 has a larger diameter than the flow hole 51.

[0041] In actual application, the first sieve hole 61 is arranged opposite to the inside of the grinding disc 5, so the diameter of the first sieve hole 61 can be set to be larger, which is beneficial to the food falling into the grinding disc 5 for grinding. The second sieve hole 62 is arranged opposite to the outside of the grinding disc 5, so the food falling from the second sieve hole 62 enters the outside of the grinding disc 5, and the food at this position needs to return to the upper cavity 11 for cutting. Therefore, the diameter of the second sieve hole 62 is smaller than that of the first sieve hole 61, so as to avoid the food falling to the outside from being too large and heavy to return to the upper cavity 11 under the action of the pressure difference. Meanwhile, the diameter of the first sieve hole 61 is larger than that of the flow hole 51, so as to prevent the unground food from entering the grinding disc 5, thereby ensuring that the unground food can return to the upper cavity 11 for cutting, and realizing the single cycle of the food, i.e. the food is cut by the stirring knife 3, falls into the grinding disc 5 from the first sieve hole 61 for grinding, and flows to the outside of the grinding disc 5 from the flow hole 51. The food outside the grinding disc 5 returns to the upper cavity 11 from the second sieve hole 62 under the action of the pressure difference for cutting again, and the process is repeated, so as to realize the multiple cutting and grinding of the food by the breaking wall machine and improve the breaking wall efficiency.

[0042] In an embodiment, the lower cavity 12 includes an inner cavity 121 and an outer cavity 122. The inner cavity 121 is located inside the grinding disc 5, and the outer cavity 122 is located outside the grinding disc 5. When the rotating shaft 2 rotates, the pressure of the upper cavity 11 is P1, and the pressure of the outer cavity 122 is P2, and P1

[0043] In actual application, when the rotating shaft 2 rotates, the stirring knife 3 rotates at high speed to generate vortex, so that the pressure P1 of the upper cavity 11 is reduced and is smaller than the pressure P2 of the outer cavity 122. Generally, the food forms fluid food when being broken. The fluid food can smoothly return to the upper cavity 11 from the outer cavity 122 through the second sieve hole 62 under the pressure difference between P1 and P2, so as to realize the repeated cutting by the stirring knife 3 and the repeated grinding by the stirring hammer 4, and realize the effect of the food cycle breaking wall.

[0044] Referring to Figure 5 The grinding disc 5 is provided with grinding teeth 52 on the side facing the stirring hammer 4. A plurality of grinding teeth 52 are arranged along the circumferential direction of the grinding disc 5. The grinding tooth 52 has a first grinding surface 521. Along the circumferential direction of the grinding disc 5, the first grinding surface 521 extends in the direction close to the stirring hammer 4. The stirring hammer 4 has a second grinding surface 421 on the side facing the grinding disc 5. Along the circumferential direction of the grinding disc 5, the second grinding surface 421 extends in the direction close to the grinding disc 5. The inclination angles of the first grinding surface 521 and the second grinding surface 421 are different.

[0045] In practical applications, the first grinding surface 521 and the second grinding surface 421 are inclinedly arranged, which can increase the contact area with the food materials, so that more food materials are ground each time the stirring hammer 4 rotates, and this design can significantly improve the grinding efficiency; at the same time, the inclined surface helps to guide the food materials to flow along a specific direction to form a continuous grinding path, which can ensure that the food materials are not stuck or accumulated in a certain area during stirring, but are uniformly ground by the stirring hammer 4 and the grinding disc 5, thereby realizing more efficient crushing and mixing. Moreover, the inclination angles of the second grinding surface 421 and the first grinding surface 521 are different, so that more food materials can be accommodated between the second grinding surface 421 and the first grinding surface 521 when the stirring hammer 4 rotates at high speed, which is beneficial to avoid the stirring hammer 4 from being stuck, and further improves the food grinding efficiency.

[0046] It should be noted that, with the outer peripheral surface of the grinding disc 5 as a reference surface, the first grinding surface 521 and the second grinding surface 421 are inclinedly arranged, specifically, the first grinding surface 521 and the outer peripheral surface intersect to form an intersection line, and the second grinding surface 421 and the outer peripheral surface intersect to form an intersection line.

[0047] Again referring to Figure 5 , the side of the stirring hammer 4 facing the grinding disc 5 has a connecting surface 422, the connecting surface 422 is parallel to the outer peripheral surface of the grinding disc 5, and the opposite sides of the connecting surface 422 are connected with the second grinding surface 421.

[0048] In practical applications, the connecting surface 422 is arranged in parallel with the outer peripheral surface of the grinding disc 5, and the opposite sides of the connecting surface 422 are connected with the second grinding surface 421, which effectively increases the gap between the stirring hammer 4 and the grinding disc 5, further avoids the probability of the stirring hammer 4 being stuck during stirring, and improves the practicability of the device.

[0049] Again referring to Figure 5 , the included angle between the first grinding surface 521 and the connecting surface 422 is smaller than the included angle between the second grinding surface 421 and the connecting surface 422. That is to say, the second grinding surface 421 is inclined at a larger angle relative to the connecting surface 422, and the second grinding surface 421 with a larger inclination angle can increase the contact area with the food materials, and better guide the food materials to form a continuous grinding path, while the first grinding surface 521 with a smaller inclination angle can further refine the grinding particles to ensure that the food materials are sufficiently ground between the stirring hammer 4 and the grinding disc 5.

[0050] Again referring to Figure 4 , the screen 6 includes an extension part 63, the extension part 63 extends towards the direction close to the grinding disc 5, and along the axial direction of the grinding disc 5, the extension part 63 wraps at least part of the outer periphery of the grinding disc 5.

[0051] In actual application, the outer periphery of the screen 6 can abut against the inner side of the shell 1 to enhance the connection stability of the screen 6 in the shell 1. The side of the screen 6 close to the grinding disc 5 is provided with an extension 63 extending towards the grinding disc 5 and wrapping around part of the outer periphery of the grinding disc 5. The extension 63 provides a mounting position for the grinding disc 5 and is beneficial to fixing the grinding disc 5, preventing the grinding disc 5 from shaking during grinding and improving the stability of the grinding disc 5 during working.

[0052] In an embodiment, the cell wall breaking machine can further comprise a base and a motor, the motor is mounted on the base, the shell 1 is placed on the base, and the rotating shaft 2 is connected with the output shaft of the motor. The rotating shaft 2 can be connected with the output shaft of the motor through a shaft coupling. The motor is used to drive the rotating shaft 2 to rotate, so that the rotating shaft 2 drives the stirring knife 3 and the stirring hammer 4 to rotate, realizing the functions of cutting and grinding food.

[0053] Referring to Figure 6 , the shell 1 comprises a shell body 13 and a cover body 14. The cover body 14 is selectively rotatably arranged relative to the shell body 13. The cover body 14 is provided with a locking groove 141 along the circumference thereof. The shell body 13 is provided with a locking buckle 131 along the circumference. The locking buckle 131 is used to lock the locking groove 141. The cover body 14 is selectively rotatable relative to the shell body 13. The cover body 14 is rotated relative to the shell body 13 to unlock or lock the locking buckle 131 and the locking groove 141.

[0054] In actual application, the shell 1 is composed of the shell body 13 and the cover body 14. The cover body 14 is provided with the feeding port 17. The cover body 14 is combined on the shell body 13 to form a closed stirring space. The cover body 14 and the shell body 13 are detachably connected. Specifically, the cover body 14 is provided with a plurality of locking grooves 141 along the circumference thereof. The locking grooves 141 comprise mutually connected inlets 1411 and locking ports 1412. The inner side of the shell body 13 is provided with a plurality of locking buckles 131 along the circumference. The cover body 14 partially extends into the shell body 13. At the same time, the locking buckles 131 extend into the locking grooves 141 from the inlets 1411. When locking is needed, the user rotates the cover body 14. The cover body 14 is rotated relative to the shell body 13 to rotate the locking buckles 131 in the locking grooves 141 to the locking ports 1412. The locking buckles 131 are locked with the locking grooves 141 at the locking ports 1412 to avoid the separation of the shell body 13 and the cover body 14. When the cover body 14 needs to be opened, the user only needs to rotate the cover body 14 in the opposite direction to unlock the locking buckles 131 and the locking grooves 141.

[0055] Referring to Figure 7The shell 1 further comprises a locking member 15 and an elastic member 16. The shell 13 is provided with a mounting groove 132. The locking member 15 is arranged in the mounting groove 132 in an axial direction. The elastic member 16 is arranged between the locking member 15 and the shell 13, and is used to push the locking member 15 in the axial direction. The locking member 15 is provided with a limiting portion 151 on a side facing the cover 14. The cover 14 is provided with an abutting portion 142. The abutting portion 142 is provided with a limiting groove 1421. When the cover 14 rotates relative to the shell 13, the abutting portion 142 is used to push the locking member 15 to move away from the cover 14, so that the abutting portion 142 enters the mounting groove 132, and the limiting portion 151 is located in the limiting groove 1421. The elastic member 16 is used to push the limiting portion 151 and the limiting groove 1421 to abut together in the axial direction.

[0056] In actual application, the locking member 15 is mainly used to lock the cover 14 and the shell 13, so as to avoid that the cover 14 is not installed in place or loosened due to vibration of the motor during work. Therefore, the locking member 15 and the elastic member 16 are arranged. When the cover 14 rotates relative to the shell 13, the abutting portion 142 of the cover 14 pushes the locking member 15 to move into the mounting groove 132. At the same time, the movement of the locking member 15 causes the elastic member 16 to be compressed. Until the limiting groove 1421 of the abutting portion 142 and the limiting portion 151 of the mounting member 7 are opposite, the elastic member 16 releases the elastic potential energy. The elastic member 16 pushes the mounting member 7 to return to the initial position, so that the limiting portion 151 is located in the limiting groove 1421 and is limited by the limiting groove 1421. The limiting groove 1421 and the limiting portion 151 can limit the cover 14 in the circumferential direction, that is, the cover 14 cannot rotate relative to the shell 13. At this time, it means that the cover 14 has been installed in place. The elastic member 16 can be a spring or the like.

[0057] It should be noted that the initial state of the elastic member 16 can be a natural state or a pre-compressed state. When the elastic member 16 is in the pre-compressed state, when the limiting groove 1421 and the limiting portion 151 are limitedly connected, the elastic member 16 can tightly abut the limiting portion 151 and the limiting groove 1421 in the axial direction due to the elastic function of the elastic member 16, so as to avoid that the limiting portion 151 and the limiting groove 1421 are separated. In this way, when the motor vibrates, the cover 14 is prevented from being separated from the mounting member 7 due to vibration, and the connection stability of the cover 14 and the shell 13 is improved.

[0058] Referring to Figure 8 The shell 13 is provided with a first abutting block 133 on a side facing the abutting portion 142. The abutting portion 142 is provided with a second abutting block 143. The first abutting block 133 is used to abut with the second abutting block 143, so as to limit the abutting portion 142 in the axial direction.

[0059] When the limiting groove 1421 and the limiting part 151 are limitedly connected, that is, the abutting part 142 and the mounting piece 7 are locked, the shell 1 simultaneously limits the abutting part 142 in the axial direction, the first abutting block 133 and the second abutting block 143 limit the cover body 14 to move in the axial direction, and it is ensured that the limiting part 151 cannot be separated from the limiting groove 1421, thereby ensuring the stability of the installation of the cover body 14.
