[0001] The present application relates to the technical field of electrical equipment, and in particular to a cup assembly and a wall breaking machine. Background Art

[0002] A cell wall breaker is a device that uses a high-speed rotating blade to break the cell wall. The higher the speed, the higher the cell wall breaking rate. However, if the cell wall breaking performance is improved by increasing the speed, it will increase the load and noise. The increase in load will increase the motor temperature and shorten the motor life. At the same time, the increase in the blade speed will increase the disturbance noise, which is not good for the user experience. Summary of the invention

[0005] In the above-mentioned cup assembly, the inner diameter of the closing part is set to be smaller than the inner diameter of the main body, and the cutter head component is located in the closing part, which is conducive to reducing the space around the cutter head component. At the same time, the ratio of the diameter of the cutting profile formed by the rotation of the cutter head component to the inner diameter of the closing part is controlled between 65% and 82%, so that a suitable space is maintained between the cutter head component and the closing part. While strengthening the turbulence intensity of the fluid around the cutter head component, it effectively promotes the rate of fluid circulation between the main body and the closing part, and increases the cutting frequency of the cutter head component. With such a design, the cup assembly improves its own structural design, increases the cutting frequency, and improves the wall breaking rate, so as to achieve a high wall breaking rate at a relatively low rotation speed, thereby improving the load and noise problems caused by high rotation speed and improving the user experience.

[0006] In some embodiments, the ratio of the diameter d1 to the inner diameter d2 further satisfies the condition: 70%≤d1 / d2≤75%.

[0007] In some embodiments, the inner wall of the main body is protrudingly provided with a spoiler rib, the spoiler rib extends along the height direction, and the thickness of the spoiler rib along the circumference of the main body gradually decreases from the end where the spoiler rib is connected to the main body to the end of the spoiler rib away from the main body.

[0008] In some embodiments, the spoiler rib includes two side walls arranged back to back in the circumferential direction of the main body, and the end of the spoiler rib away from the main body has a spoiler centerline parallel to the axis of the main body, the perpendicular line between the spoiler centerline and the axis of the main body is a radial line, and the angle between at least one of the two side walls and the radial line is denoted as γ; wherein 30°≤γ≤45°.

[0009] In some embodiments, the angle γ further satisfies the condition: 35°≤γ≤40°.

[0010] In some embodiments, the height of the spoiler rib protruding from the inner wall of the main body is recorded as L2, and the radial height between the inner wall of one end of the closing portion close to the main body and the inner wall of the main body is recorded as L1, wherein L2≥L1.

[0011] In some embodiments, a limit line for indicating a maximum liquid level is provided on an inner wall of the main body, and the spoiler rib is located on a side of the limit line facing the closing portion.

[0012] In some embodiments, the cup body further includes a transition portion, which is disposed between the main body and the closing portion, and an inner diameter of the transition portion gradually decreases from one end of the transition portion close to the main body to another end of the transition portion close to the closing portion.

[0013] In some embodiments, the cup assembly further comprises a heating element, wherein the heating element is disposed at one end of the closing portion away from the transition portion, and the cutter head component is rotatably disposed on the heating element.

[0014] In some embodiments, the maximum value of the distance between one end of the cutter head component away from the heat generating element and the surface of the heat generating element is recorded as h2, and the distance between one end of the transition portion close to the main body portion and the surface of the heat generating element is recorded as h1, wherein 75%≤h1 / h2≤100%.

[0016] A wall breaking machine comprises: a base; a driving member arranged on the base; a cup assembly as described in any one of the above items, wherein the bottom of the cup body is arranged on the base, and the driving member is used to drive the cutter head component to rotate around its own axis.

[0017] The above-mentioned wall breaking machine adopts the above-mentioned cup assembly, and sets the inner diameter of the closing part to be smaller than the inner diameter of the main body, and the cutter head component is located in the closing part, which is conducive to reducing the space around the cutter head component. At the same time, the ratio of the diameter of the cutting profile formed by the rotation of the cutter head component to the inner diameter of the closing part is controlled between 65% and 85%, so that a suitable space is maintained between the cutter head component and the closing part, while strengthening the turbulence intensity of the fluid around the cutter head component, effectively promoting the rate of the fluid circulating up and down between the main body and the closing part, and increasing the cutting frequency of the cutter head component. With such a design, the cup assembly improves its own structural design, increases the cutting frequency, and improves the wall breaking rate, so as to achieve a high wall breaking rate at a relatively low rotation speed, thereby improving the load and noise problems caused by high rotation speed and improving the user experience.

[0032] A wall breaker is a device that uses a high-speed rotating blade to break cell walls. The higher the speed, the higher the wall breaking rate. However, if the wall breaking performance is improved by increasing the speed, it will bring about problems of increased load and noise. The increased load will increase the temperature of the motor, resulting in a shortened motor life, which is not conducive to the safety of use and the service life of the entire machine. At the same time, the increased speed of the blade will increase the noise that disturbs the flow, resulting in a poor user experience of the device. In addition, if the speed of the blade is reduced, although the load and noise can be effectively reduced, the wall breaking rate will be reduced, weakening the wall breaking performance of the wall breaker.

[0033] Based on this, please refer to Figure 1 and Figure 2 The present application provides a cup assembly 100, which includes: a cup body 10 and a cutter head component 20. The cup body 10 includes a main body 11 and a closing portion 12 in sequence along its own height direction X, and the inner diameter of the closing portion 12 is smaller than the inner diameter of the main body 11; the cutter head component 20 is rotatably arranged in the closing portion 12, and the cutter head component 20 rotates around its own axis to form a circular cutting profile 23, the diameter of the cutting profile 23 is recorded as d1, and the inner diameter of the closing portion 12 is recorded as d2, wherein 65%≤d1 / d2≤82%.

[0034] In the cup assembly 100, the inner diameter of the closing portion 12 is set smaller than the inner diameter of the main body 11, and the cutter head component 20 is located in the closing portion 12, which is conducive to reducing the space around the cutter head component 20. At the same time, the ratio of the diameter of the cutting profile 23 formed by the rotation of the cutter head component 20 to the inner diameter of the closing portion 12 is controlled between 65% and 82%, so that a suitable space is maintained between the cutter head component 20 and the closing portion 12, while strengthening the turbulence intensity of the fluid around the cutter head component 20, effectively promoting the rate of fluid circulation between the main body 11 and the closing portion 12, and increasing the cutting frequency of the cutter head component 20. With such a design, the cup assembly 100 improves its own structural design, increases the cutting frequency, and improves the wall breaking rate, so as to achieve a high wall breaking rate at a relatively low rotation speed, thereby improving the load and noise problems caused by high rotation speed and improving user experience.

[0035] It should be noted that if the ratio of the diameter of the cutting profile 23 of the cutter head component 20 to the inner diameter of the closing portion 12 is too large, the space between the cutter head component 20 and the inner wall of the closing portion 12 will be small, which will not promote the effective circulation of the fluid between the main body 11 and the closing portion 12, and reduce the cutting frequency of the cutter head component 20. If the ratio of the diameter of the cutting profile 23 of the cutter head component 20 to the inner diameter of the closing portion 12 is too small, the space between the cutter head component 20 and the inner wall of the closing portion 12 will be large. At this time, the closer the fluid is to the inner wall of the closing portion 12, the weaker the disturbance caused by the cutter head component 20, resulting in a decrease in the turbulence intensity of the fluid around the cutter head component 20.

[0036] To this end, the ratio of the diameter of the cutting profile 23 of the cutter head component 20 to the inner diameter of the closing portion 12 is controlled between 65% and 82%, for example, but not limited to 65%, 67%, 69%, 70%, 72%, 74%, 75%, 78%, 80%, 82%, etc. This effectively takes into account the turbulence intensity of the fluid and the rate of up and down circulation, and improves the cutting frequency of the cutter head component 20. Compared with the traditional wall breaking machine, the wall breaking machine of this embodiment can adopt a relatively low rotation speed to achieve a higher wall breaking rate.

[0037] Among them, the low speed of the wall breaking machine is relative to the traditional wall breaking machine. For example, taking soy milk as an example, in order to achieve a soy milk wall breaking rate of 10g / L ~ 20g / L, the speed of the blade component 20 of this embodiment can be 7000rpm ~ 9000rpm, etc.

[0038] It should also be noted that the cutting profile 23 of the cutter head component 20 refers to the part of the cutter head component 20 that is farthest from its own axis during the rotation of the cutter head component 20, which rotates around the axis to form a circular structure, which can be the cutting profile 23 of the cutter head component 20. Among them, the diameter of the cutting profile 23 of the cutter head component 20 can be twice the maximum radial distance between the cutter head component 20 and its own axis. At the same time, the inner wall of the main body 11 and the inner wall of the closing part 12 can both be cylindrical structures; of course, in some embodiments, at least one of the inner wall of the main body 11 and the inner wall of the closing part 12 can also be designed as a truncated cone structure, in which case the maximum inner diameter of the closing part 12 is also smaller than the minimum inner diameter of the main body 11.

[0039] For further information, please refer to Figure 2 , the ratio of the diameter d1 to the inner diameter d2 also satisfies the condition of: 70%≤d1 / d2≤75%. It can be seen that the ratio of the diameter of the cutting profile 23 of the cutter head component 20 to the inner diameter of the closing portion 12 is further controlled between 70% and 75%, for example: it can be but not limited to 70%, 71%, 72%, 73%, 74%, 75%, etc. In this way, the ratio of the diameter d1 to the inner diameter d2 is further limited to between 70% and 75%, so as to further effectively take into account the turbulence intensity and the cutting efficiency of the cutter head component 20, and improve the wall breaking rate of the wall breaking machine.

[0040] It should be noted that, when the size of the blade component 20 is determined, the smaller the ratio of the diameter of the cutting profile 23 of the blade component 20 to the inner diameter of the closing portion 12 is, the larger the inner diameter of the closing portion 12 is. Since the inner diameter of the closing portion 12 is smaller than the inner diameter of the main body 11, the smaller the difference in thickness between the closing portion 12 and the main body 11 is, the less material is used for the cup body 10, and the lighter the cup body 10 is. For this reason, the ratio of the diameter of the cutting profile 23 of the blade component 20 to the inner diameter of the closing portion 12 can be specifically 70%.

[0041] The size of the cutter head component 20 may be determined according to the capacity of the wall breaking machine. For example, the diameter d1 of the cutting profile 23 of the cutter head component 20 may be, but is not limited to, 60 mm to 90 mm.

[0042] In some embodiments, please refer to Figure 1, the inner wall of the main body 11 is convexly provided with a spoiler rib 14, the spoiler rib 14 extends along the height direction X, and the thickness of the spoiler rib 14 along the circumference of the main body 11 gradually decreases from the end where the spoiler rib 14 is connected to the main body 11 to the end where the spoiler rib 14 is away from the main body 11. It can be seen that the introduction of the spoiler rib 14 on the inner wall of the main body 11 can enhance the spoiler effect of the fluid in the main body 11. At the same time, the farther the spoiler rib 14 is from the inner wall of the main body 11, the thinner its thickness is, so that the fluid flowing along the inner wall of the main body 11 flows along the side of the spoiler rib 14 and passes over the spoiler rib 14, so that the fluid generates partial spoiler in the radial direction of the main body 11, and the spoiler strength is strengthened, which is not only conducive to uniform crushing of the fluid, but also conducive to improving the wall breaking rate of the wall breaking machine.

[0043] It should be noted that the further away the spoiler rib 14 is from the main body 11, the thinner its thickness is, which means that at least one side of the spoiler rib 14 along the circumference of the main body 11 is inclined or curved. At this time, the fluid flowing on the inner wall of the main body 11 will be blocked by the spoiler rib 14, and flow along the side of the spoiler rib 14 with an inclined or curved design to the inside of the main body 11, and mix with the fluid inside the main body 11, resulting in a partial spoiler effect.

[0044] Optionally, the number of the spoiler ribs 14 may be one or more. When the number of the spoiler ribs 14 is more than one, all the spoiler ribs 14 may be arranged at intervals along the circumference of the main body 11. At the same time, there are many ways to fix the spoiler ribs 14 on the inner wall of the main body 11, such as but not limited to bolt connection, clamping, riveting, bonding, welding, etc.; of course, the spoiler ribs 14 may also be integrally formed on the inner wall of the main body 11 by injection, die casting, 3D printing, punching, etc.

[0045] For further information, please refer to Figure 3 and Figure 4 The spoiler rib 14 includes two side walls 141 disposed in opposite directions to each other in the circumferential direction of the main body 11, and the end of the spoiler rib 14 away from the main body 11 has a spoiler center line 142 parallel to the axis of the main body 11, and the perpendicular line between the spoiler center line 142 and the axis of the main body 11 is a radial line 143, and the angle between at least one of the two side walls 141 and the radial line 143 is denoted as γ; wherein 30°≤γ≤45°. It can be seen that at least one of the two side walls 141 is disposed at an angle relative to the radial direction of the main body 11, so that the fluid can flow along the inclined side wall 141 and flow toward the inside of the main body 11, thereby achieving an effective spoiler effect.

[0046] It should be noted that the spoiler center line 142 refers to the center line of the end of the spoiler rib 14 away from the main body 11, and the spoiler center line 142 extends along the height direction X of the main body 11 and is parallel to the axis of the main body 11. For example, when the end of the spoiler rib 14 away from the main body 11 is a plane, all the centers of the plane in the circumferential direction of the main body 11 are connected, and the obtained connection line is the spoiler center line 142; when the end of the spoiler rib 14 away from the main body 11 is a curved surface, all the centers of the curved surface in the circumferential direction of the main body 11 are connected, and the obtained connection line is the spoiler center line 142. Of course, in some embodiments, when the end of the spoiler rib 14 away from the main body 11 is a curved surface, the end line of the spoiler rib 14 farthest from the main body 11 can be used as the spoiler center line 142.

[0047] The radial line 143 refers to the perpendicular line between the spoiler center line 142 and the axis of the main body 11, and can also be understood as the diameter direction of the spoiler center line 142 on the main body 11. One of the two side walls 141 in the spoiler rib 14 can be designed as an inclined surface. In this case, the rotation direction of the motor should be designed to drive the fluid to impact the inclined side wall 141. In some specific embodiments, both side walls 141 are inclined relative to the radial line 143, and the two side walls 141 are inclined to each other in the direction facing each other.

[0048] It should also be noted that if the angle between the side wall 141 and the radial line 143 is too large, the resistance of the fluid will be increased too much, causing the wall breaker to shake violently during stirring; at the same time, if the angle is too small, it will not have an effective turbulence effect.

[0049] To this end, in this embodiment, the angle between the side wall 141 and the radial line 143 can be set between 30° and 45°, for example, but not limited to 30°, 32°, 34°, 36°, 38°, 40°, 42°, 44°, 45°, etc. In this way, the turbulence effect is enhanced and the wall breaking rate of the wall breaking machine is improved while ensuring the stable operation of the wall breaking machine.

[0050] For further information, please refer to Figure 4 , the angle γ also satisfies the condition: 35°≤γ≤40°. It can be seen that the angle between the side wall 141 and the radial line 143 can be further set between 35° and 40°, for example, but not limited to 35°, 36°, 37°, 38°, 39°, 40°, etc. In this way, the fluid can flow more stably along the inclined side wall 141 and flow into the interior of the main body 11, further improving the turbulence effect of the fluid.

[0051] Specifically, in some embodiments, in order to obtain the change of the simulated turbulent kinetic energy with the ratio of the diameter d1 to the inner diameter d2, the angle γ can be set to 38°, and the distance between the inner wall of the closing portion 12 and the inner diameter of the main body 11 is 7 mm. At this time, in the simulation software, the ratio of the diameter d1 to the inner diameter d2 is changed to obtain the corresponding turbulent kinetic energy. For details, please refer to Figure 5 .from Figure 5 It can be seen that the turbulent kinetic energy increases first and then decreases as the ratio of diameter d1 to inner diameter d2 increases. When the ratio of diameter d1 to inner diameter d2 reaches 65%, the turbulent kinetic energy can reach 0.2337m 2 / S 2 ; When the ratio of diameter d1 to inner diameter d2 reaches 82%, the turbulent kinetic energy can reach 0.234m 2 / S 2 At the same time, when the ratio of diameter d1 to inner diameter d2 reaches 75%, the turbulent kinetic energy can reach as high as 0.3043m 2 / S 2 Therefore, when the ratio of diameter d1 to inner diameter d2 is controlled between 65% and 82%, the turbulent kinetic energy reaches 0.2337m 2 / S 2 All of the above makes the wall breaking machine have higher wall breaking performance.

[0052] Among them, it should be noted that Figure 5 The broken line 1 in the figure refers to the broken line formed by linearly connecting the turbulent kinetic energy data. Figure 5 Curve 2 in FIG. 1 is the curve fitted based on various turbulent kinetic energy data.

[0053] In some embodiments, please refer to Figure 3 , the height of the spoiler rib 14 protruding from the inner wall of the main body 11 is recorded as L2, and the radial height between the inner wall of the end of the closing part 12 close to the main body 11 and the inner wall of the main body 11 is recorded as L1, where L2≥L1. It can be seen that the height of the spoiler rib 14 protruding from the main body 11 exceeds or is flush with the inner wall of the closing part 12. In this way, the spoiler rib 14 maintains a reasonable protrusion height, thereby playing a better spoiling role on the fluid circulating from the closing part 12 to the main body 11, further strengthening the spoiler strength, which is conducive to improving the wall breaking performance of the wall breaking machine.

[0054] In some embodiments, please refer to Figure 4 The inner wall of the main body 11 has a limit line 111 for indicating the maximum volume liquid level, and the spoiler rib 14 is located on the side of the limit line 111 facing the closing portion 12. It can be seen that the height between the end of the spoiler rib 14 away from the closing portion 12 and the bottom of the closing portion 12 is less than the height between the limit line 111 and the bottom of the closing portion 12, so that the spoiler rib 14 can effectively spoil the flow below the limit line 111.

[0055] It should be noted that the maximum capacity liquid level refers to the maximum liquid level of the fluid allowed by the wall breaking machine in the cup body 10.

[0056] In some embodiments, please refer to Figure 1 The cup body 10 further includes a transition portion 13, which is disposed between the main body 11 and the closing portion 12, and the inner diameter of the transition portion 13 gradually decreases from one end of the transition portion 13 close to the main body 11 to the other end of the transition portion 13 close to the closing portion 12. It can be seen that when the cutter head component 20 rotates around its own axis, the fluid will circulate between the closing portion 12 and the main body 11. Since the closer the transition portion 13 is to the closing portion 12, the smaller its inner diameter is, the main body 11 and the closing portion 12 are smoothly connected by the transition portion 13, which makes the circulation of the fluid between the closing portion 12 and the main body 11 smoother, which is beneficial to improve the cutting frequency of the cutter head component 20.

[0057] It should be noted that the transition portion 13 is an annular structure between the main body 11 and the closing portion 12. In order to achieve that the closer the transition portion 13 is to the closing portion 12, the smaller its inner diameter is, the inner wall of the transition portion 13 can be designed as an inclined plane; or the inner wall of the transition portion 13 can be designed as an arc surface, etc.

[0058] In some embodiments, please refer to Figure 1 The cup assembly 100 further includes a heating element 30, which is disposed at one end of the closing portion 12 away from the transition portion 13, and the blade component 20 is rotatably disposed on the heating element 30. It can be seen that the introduction of the heating element 30 facilitates heating the inside of the cup body 10, so that food can be crushed and heated at the same time.

[0059] The heating element 30 may be designed as a disc-shaped structure and arranged at the bottom of the closing portion 12. At the same time, it should be noted that the end of the blade component 20 away from the heating element 30 may be located inside the transition portion 13, that is, the end of the blade component 20 away from the heating element 30 does not extend beyond the end where the transition portion 13 is connected to the main body 11; or, the end of the blade component 20 away from the heating element 30 may also be located outside the transition portion 13, that is, the end of the blade component 20 away from the heating element 30 extends beyond the end where the transition portion 13 is connected to the main body 11.

[0060] For further information, please refer to Figure 4, the maximum value of the distance between the end of the blade component 20 away from the heating element 30 and the surface of the heating element 30 is recorded as h2, and the distance between the end of the transition portion 13 close to the main body 11 and the surface of the heating element 30 is recorded as h1, wherein 75%≤h1 / h2≤100%. It can be seen that one end of the blade component 20 exceeds or is flush with the end of the transition portion 13 close to the main body 11. For this reason, the ratio of h1 to h2 can be between 75% and 100%, for example: it can be but not limited to 75%, 80%, 85%, 90%, 95%, 100%, etc. With such a design, the ratio of the height of one end of the blade component 20 from the heating element to the height of the end of the transition portion 13 close to the main body 11 from the heating element is controlled to be 75%~100%, so that the turbulence effect of the fluid in the cup body 10 is better, and the wall breaking rate is further improved.

[0061] It should be noted that the blade head component 20 includes a rotating shaft 21 and a plurality of blades 22 disposed on the rotating shaft 21, the rotating shaft 21 can be rotatably disposed on the heating element 30, the end of each blade 22 connected to the rotating shaft 21 can be located in the closing portion 12, and the end of each blade 22 away from the rotating shaft 21 can be flush with or beyond the end of the transition portion 13 close to the main body 11. At this time, the distance h2 is the maximum value of the distances between the end of each blade 22 away from the rotating shaft 21 and the surface of the heating element.

[0062] When the inner wall of the main body 11 is provided with a spoiler rib 14, one end of the spoiler rib 14 may extend to the transition portion 13; or the spoiler rib 14 may be spaced apart from the transition portion 13 in the height direction X of the main body 11. Specifically, in some embodiments, the transition portion 13 is provided with a notch 131, and the spoiler rib 14 extends into the notch 131 along the height direction X of the main body 11. In addition, the distance between the end of the spoiler rib 14 away from the transition portion 13 and the heating element is recorded as h3, and the distance between the limit line 111 in the main body 11 and the heating element is recorded as h4, where h4≥h3.

[0063] To obtain the change of the ratio of h1 to h2 in the simulation turbulent kinetic energy, the distance h3 can be set to 112 mm. At this time, in the simulation software, change the ratio of h1 to h2 to obtain the corresponding turbulent kinetic energy. For details, please refer to Figure 6 .from Figure 6 It can be seen that the turbulent kinetic energy increases first and then decreases as the ratio of h1 to h2 increases. When the ratio of h1 to h2 reaches 75%, the turbulent kinetic energy can reach 0.7019m 2 / S 2 ; When the ratio of h1 to h2 reaches 100%, the turbulent kinetic energy can reach 0.6970m 2 / S 2 Therefore, when the ratio of h1 to h2 is controlled between 75% and 100%, the turbulent kinetic energy reaches 0.7019m 2 / S 2All of the above makes the wall breaking machine have higher wall breaking performance.

[0064] Among them, it should be noted that Figure 6 The broken line 3 in the figure refers to the broken line formed by linearly connecting the various turbulent kinetic energy data; Figure 6 Curve 4 in FIG. 4 is a curve fitted based on various turbulent kinetic energy data.

[0065] In addition, in order to make the purpose, technical solutions and advantages of the present application more concise and clear, the present application is described with the following specific embodiments, but the present application is by no means limited to these embodiments. The embodiments described below are only preferred embodiments of the present application and can be used to describe the present application, and cannot be understood as limiting the scope of the present application. It should be pointed out that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.

[0066] In the comparative example, the ratio of the diameter of the cutting profile 23 of the blade component 20 in the wall breaking machine to the inner diameter of the closing portion 12, that is, the ratio of the diameter d1 to the inner diameter d2 is 63.6%; the ratio of the height of one end of the blade component 20 from the heating element to the height of the end of the transition portion 13 close to the main body 11 from the heating element, that is, the ratio of h1 to h2 is 0%, that is, there is no closing portion 12, and h1 is 0mm. The specific operation steps are:

[0067] Weigh 125g of soaked beans and add them to the cup 10 of the wall-breaking machine, add water to 1L; turn on the soy milk function, control the speed of the blade component 20 to 8000rpm, and after the beating is completed, pour the soy milk into an 80-mesh screen and rinse with clean water for 3 minutes; lay the screen flat and stand for 5 minutes to drain the clear water; weigh the weight and subtract the weight of the screen to obtain the amount of wet residue in the soy milk. At the same time, the sound power noise of the wall-breaking machine is measured when it is working, and the details can be referred to Table 1.

[0068] In the embodiment, the ratio of the diameter of the cutting profile 23 of the blade component 20 in the wall breaking machine to the inner diameter of the closing portion 12 is 70%; the ratio of the height of one end of the blade component 20 from the heating element to the height of one end of the transition portion 13 close to the main body 11 from the heating element is 75%. Since the specific operating steps of the embodiment are consistent with the specific operating steps of the comparative example, they are not described here in detail. Please refer to Table 1 for specific experimental data.

[0069] Table 1

[0070] serial number Tool diameter ratio Blade height ratio Speed ​​rpm Sound power noise dB Wall breaking rate (wet residue g) Comparative Example 63.6% 0% 8000 72.3 28 Example 70% 75% 8000 69.1 14.5

[0071] It can be seen that, under the same blade component 20 and the same rotation speed, the ratio of the diameter of the cutting profile 23 of the blade component 20 in the wall breaking machine to the inner diameter of the closing portion 12 is 70%; the ratio of the height of one end of the blade component 20 from the heating element to the height of the end of the transition portion 13 close to the main body 11 from the heating element is 75%. Compared with the comparative scheme, the noise is reduced by 2dB, the wall breaking rate is increased by nearly 1 times, and the wall breaking rate is significantly improved.

[0072] For further information, please refer to Figure 4 , the ratio of distance h1 to distance h2 also satisfies the condition: 75%≤h1 / h2≤85%. It can be seen that the ratio of the distance between the transition portion 13 and the heating element and the distance between the blade component 20 and the heating element is further controlled between 75% and 85%, for example, but not limited to 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 4%, 85%, etc. In this way, the ratio of h1 to h2 is further limited between 75% and 85%, further improving the wall breaking rate of the wall breaking machine.

[0073] In some embodiments, please refer to Figure 7 The present application provides a wall breaking machine, which includes: a base 200; a driving member 300, which is arranged on the base 200; like any of the cup assemblies 100 above, the bottom of the cup body 10 is arranged on the base 200, and the driving member 300 is used to drive the blade head component 20 to rotate around its own axis.

[0074] The wall breaking machine mentioned above adopts the above cup assembly 100, sets the inner diameter of the closing part 12 smaller than the inner diameter of the main body 11, and the blade component 20 is located in the closing part 12, which is conducive to reducing the space around the blade component 20. At the same time, the ratio of the diameter of the cutting profile 23 formed by the rotation of the blade component 20 to the inner diameter of the closing part 12 is controlled between 65% and 85%, so that a suitable space is maintained between the blade component 20 and the closing part 12, while strengthening the turbulence intensity of the fluid around the blade component 20, effectively promoting the rate of the fluid circulating up and down between the main body 11 and the closing part 12, and increasing the cutting frequency of the blade component 20. With such a design, the cup assembly 100 improves its own structural design, increases the cutting frequency, and improves the wall breaking rate, so as to achieve a high wall breaking rate at a relatively low rotation speed, thereby improving the load and noise problems caused by high rotation speed and improving user experience.

[0075] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0076] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
