[0028] In addition, if these terms "first", "second" appear, these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features referred to. Therefore, the features defined with "first", "second" can include at least one of the features explicitly or implicitly. In the description of the present application, if the term "a plurality of" appears, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise explicitly specified.

[0029] In the present application, unless otherwise explicitly specified and limited, if the terms "mounting", "connecting", "connecting", "fixing" and the like appear, these terms should be interpreted broadly. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0030] In the present application, unless specifically defined and limited otherwise, if there is a description of a first feature "on" or "under" a second feature, etc., it can mean that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium.

If an element is considered to be "connected" to another element, it can be directly connected to another element or there can be a middle element.

[0032] The homogenizer refers to a device that breaks the cell wall by using a high-speed rotating cutter head. The higher the speed, the higher the breaking rate. However, if the breaking performance is improved by increasing the speed, the load and noise will increase, and the increase in load will cause the motor temperature to rise, resulting in a shortened motor life, which is not conducive to use safety and the service life of the whole machine. At the same time, increasing the speed of the cutter head will increase the noise of the whipping disturbance, resulting in a poor user experience of the device. In addition, if the speed of the cutter head is reduced, although the load and noise can be effectively reduced, the breaking rate will be reduced, and the breaking performance of the homogenizer will be weakened.

[0033] Based on this, please refer to Figure 1 and Figure 2 The present application provides a cup assembly 100, which comprises a cup body 10 and a cutter head component 20. The cup body 10 comprises a main body portion 11 and a necked portion 12 in sequence along the height direction X of the cup body 10, and the inner diameter of the necked portion 12 is smaller than that of the main body portion 11; the cutter head component 20 is rotatably arranged in the necked 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 denoted as d1, and the inner diameter of the necked portion 12 is denoted as d2, wherein 65%≤d1 / d2≤82%.

[0034] The cup assembly 100 described above is provided with the inner diameter of the necked portion 12 being smaller than the inner diameter of the main body portion 11, and the cutter head component 20 is located in the necked portion 12, which is beneficial to reduce 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 necked portion 12 is controlled to be between 65% and 82%, so that a suitable space is maintained between the cutter head component 20 and the necked portion 12, while strengthening the turbulence intensity of the fluid around the cutter head component 20, effectively promoting the rate of circulation of the fluid between the main body portion 11 and the necked portion 12, and increasing the cutting frequency of the cutter head component 20. In this way, the cup assembly 100 improves the cutting frequency and the wall breaking rate by improving the structural design of the cup assembly 100, facilitates the realization of a high wall breaking rate at a relatively low speed, and further improves the load and noise problems caused by high speed, thereby improving the 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 necked portion 12 is too large, the space between the cutter head component 20 and the inner wall of the necked portion 12 will be small, which cannot promote the effective circulation of the fluid between the main body portion 11 and the necked 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 necked portion 12 is too small, the space between the cutter head component 20 and the inner wall of the necked portion 12 will be large. At this time, the fluid closer to the inner wall of the necked portion 12 is less disturbed by the beating of the cutter head component 20, which reduces the turbulence intensity of the fluid around the cutter head component 20.

[0036] Therefore, the ratio of the diameter of the cutting profile 23 of the cutter head component 20 to the inner diameter of the necked portion 12 is controlled to be between 65% and 82%, such as but not limited to 65%, 67%, 69%, 70%, 72%, 74%, 75%, 78%, 80%, 82%, etc. In this way, the turbulence intensity and the rate of circulation of the fluid are effectively balanced, and the cutting frequency of the cutter head component 20 is improved. Compared with the traditional wall breaking machine, the wall breaking machine of the present embodiment can use a relatively low 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 soybean milk as an example, in order to achieve a soybean milk wall breaking rate of 10g / L ~20g / L, the speed of the cutter head component 20 of the present embodiment can be 7000rpm ~9000rpm, etc.

[0038] It should 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 away from the axis of the cutter head component 20 during rotation of the cutter head component 20 about the axis to form a circular structure that can be the cutting profile 23 of the cutter head component 20. The diameter of the cutting profile 23 of the cutter head component 20 can be twice the maximum radial distance between the axis of the cutter head component 20 and the cutter head component 20. Meanwhile, the inner wall of the main body portion 11 and the inner wall of the tapered portion 12 can both be cylindrical structures; of course, in some embodiments, at least one of the inner wall of the main body portion 11 and the inner wall of the tapered portion 12 can also be designed as a circular truncated cone structure, in which case the maximum inner diameter of the tapered portion 12 is also smaller than the minimum inner diameter of the main body portion 11.

[0039] Further, please refer to Figure 2 The ratio of the diameter d1 and the inner diameter d2 also satisfies the condition: 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 and the inner diameter of the tapered portion 12 is further controlled between 70% and 75%, such as: but not limited to 70%, 71%, 72%, 73%, 74%, 75%, etc. In this way, the ratio of the diameter d1 and the inner diameter d2 is further limited between 70% and 75%, which facilitates further effectively balancing the turbulence intensity and the cutting efficiency of the cutter head component 20, and improving the breaking rate of the wall breaking machine.

[0040] It should be noted that when the size of the cutter head component 20 is determined, the smaller the ratio of the diameter of the cutting profile 23 of the cutter head component 20 and the inner diameter of the tapered portion 12, the larger the inner diameter of the tapered portion 12. Since the inner diameter of the tapered portion 12 is smaller than the inner diameter of the main body portion 11, the smaller the difference between the thicknesses of the tapered portion 12 and the main body portion 11, the less material the cup body 10 uses and the lighter the cup body 10 is. Therefore, the ratio of the diameter of the cutting profile 23 of the cutter head component 20 and the inner diameter of the tapered portion 12 can be 70% in particular.

[0041] The size of the cutter head component 20 can be determined according to the capacity of the wall breaking machine, such as: the diameter d1 of the cutting profile 23 of the cutter head component 20 can be but not limited to 60mm-90mm.

[0042] In some embodiments, please refer to Figure 1The inner wall of the main body 11 is 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 circumferential direction of the main body 11 gradually decreases from one end of the spoiler rib 14 connected to the main body 11 to the other end of the spoiler rib 14 away from the main body 11. Therefore, the spoiler rib 14 introduced on the inner wall of the main body 11 can enhance the flow disturbance effect of the fluid in the main body 11. At the same time, the farther the spoiler rib 14 is away from the inner wall of the main body 11, the thinner the thickness of the spoiler rib 14. In this way, the fluid flowing along the inner wall of the main body 11 can flow along the side surface of the spoiler rib 14 and pass through the spoiler rib 14, so that the fluid generates partial flow disturbance in the radial direction of the main body 11, thereby strengthening the flow disturbance intensity, which is not only beneficial to uniform fragmentation of the fluid, but also beneficial to improving the wall breaking rate of the wall breaking machine.

[0043] It should be noted that the farther the spoiler rib 14 is away from the main body 11, the thinner the thickness of the spoiler rib 14, which means that at least one side of the spoiler rib 14 along the circumferential direction of the main body 11 is designed to be inclined or curved. At this time, the fluid flowing along the inner wall of the main body 11 will be disturbed by the spoiler rib 14, and will flow along the side of the spoiler rib 14 designed to be inclined or curved towards the inside of the main body 11, and will mix with the fluid in the inside of the main body 11, thereby causing partial flow disturbance effect.

[0044] Alternatively, the number of spoiler ribs 14 can be one or multiple. When the number of spoiler ribs 14 is multiple, all the spoiler ribs 14 can be arranged at intervals along the circumferential direction of the main body 11. At the same time, the spoiler rib 14 can be fixed on the inner wall of the main body 11 in various ways, such as but not limited to bolt connection, clamping, riveting, bonding, welding, etc. Of course, the spoiler rib 14 can also be integrally formed on the inner wall of the main body 11 by injection, die casting, 3D printing, punching, etc.

[0045] Further, please refer to Figure 3 and Figure 4 The spoiler rib 14 includes two side walls 141 arranged opposite 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 flow disturbance center line 142 parallel to the axis of the main body 11. The perpendicular line between the flow disturbance center line 142 and the axis of the main body 11 is a radial connecting line 143. Among the two side walls 141, the angle between at least one side wall 141 and the radial connecting line 143 is denoted as γ; wherein 30°≤γ≤45°. Therefore, at least one of the two side walls 141 is arranged to be inclined relative to the radial direction of the main body 11, so that the fluid can flow along the inclined side wall 141 and flow into the inside of the main body 11, thereby achieving effective flow disturbance effect.

[0046] It should be noted that the disturbance center line 142 refers to the center line on the end of the disturbance rib 14 away from the main body 11, which 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 disturbance rib 14 away from the main body 11 is a plane, all centers on the circumferential direction of the main body 11 are connected, and the obtained connecting line is the disturbance center line 142; when the end of the disturbance rib 14 away from the main body 11 is an arc surface, all centers on the circumferential direction of the main body 11 are connected, and the obtained connecting line is the disturbance center line 142. Of course, in some embodiments, when the end of the disturbance rib 14 away from the main body 11 is an arc surface, the end of the disturbance rib 14 farthest away from the main body 11 can be taken as the disturbance center line 142.

[0047] The radial connecting line 143 refers to the perpendicular line between the disturbance center line 142 and the axis of the main body 11, which can also be understood as the diameter direction of the disturbance center line 142 on the main body 11. Among the two side walls 141 of the disturbance rib 14, one can be designed as an inclined surface, at this time, the rotation direction of the motor should be designed to be the direction that can drive the fluid to impact on the inclined side wall 141. Specifically, in some embodiments, both side walls 141 are inclined relative to the radial connecting line 143, and the two side walls 141 are inclined to each other in the direction toward each other.

[0048] It should be noted that if the angle between the side wall 141 and the radial connecting line 143 is too large, it will greatly increase the resistance of the fluid, causing the wall breaking machine to shake violently during stirring; at the same time, if the value is too small, it cannot effectively disturb the flow.

[0049] Therefore, the angle between the side wall 141 and the radial connecting line 143 can be between 30° and 45°, such as: but not limited to 30°, 32°, 34°, 36°, 38°, 40°, 42°, 44°, 45°, etc. In this way, under the premise of ensuring the stable working of the wall breaking machine, the disturbance effect is strengthened, and the wall breaking rate of the wall breaking machine is improved.

[0050] Further, 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 connecting line 143 can be further between 35° and 40°, such as: 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 to the inside of the main body 11, further improving the disturbance effect of the fluid.

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

[0052] It should be noted that, Figure 5 the broken line 1 refers to a broken line formed by linearly connecting each turbulent kinetic energy data; Figure 5 the curve 2 refers to a curve fitted according to each turbulent kinetic energy data.

[0053] In some embodiments, please refer to Figure 3 , the height of the turbulence rib 14 protruding from the inner wall of the main body portion 11 is L2, and the radial height between the inner wall of the end of the neck portion 12 close to the main body portion 11 and the inner wall of the main body portion 11 is L1, wherein L2≥L1. It can be seen that the height of the turbulence rib 14 protruding from the main body portion 11 exceeds or is flush with the inner wall of the neck portion 12. In this way, the turbulence rib 14 maintains a reasonable protruding height, thereby playing a better turbulence effect on the fluid circulating from the neck portion 12 to the main body portion 11, further strengthening the turbulence intensity, and being beneficial 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 portion 11 has a limit line 111 for indicating the maximum capacity liquid level, and the turbulence rib 14 is located on the side of the limit line 111 towards the neck portion 12. It can be seen that the height between the end of the turbulence rib 14 away from the neck portion 12 and the bottom of the neck portion 12 is less than the height between the limit line 111 and the bottom of the neck portion 12, so that the turbulence rib 14 effectively disturbs 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, referring to Figure 1 The cup body 10 further comprises a transition portion 13, which is arranged between the main body portion 11 and the necked portion 12, and the inner diameter of the transition portion 13 gradually decreases from the end of the transition portion 13 close to the main body portion 11 to the end of the transition portion 13 close to the necked portion 12. It can be seen that when the cutter head component 20 rotates around its own axis, the fluid will circulate between the necked portion 12 and the main body portion 11. Since the closer the transition portion 13 is to the necked portion 12, the smaller the inner diameter of the transition portion 13, the main body portion 11 and the necked portion 12 are smoothly connected through the transition portion 13, which makes the circulation of the fluid between the necked portion 12 and the main body portion 11 more smooth, and is beneficial to improve the cutting frequency of the cutter head component 20.

[0057] It should be noted that the transition portion 13 presents a circular ring structure between the main body portion 11 and the necked portion 12, in order to realize that the closer the transition portion 13 is to the necked portion 12, the smaller the inner diameter of the transition portion 13, 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 also be designed as a circular arc surface, etc.

[0058] In some embodiments, referring to Figure 1 The cup assembly 100 further comprises a heating element 30, which is arranged at the end of the necked portion 12 away from the transition portion 13, and the cutter head component 20 is rotatably arranged on the heating element 30. It can be seen that the introduction of the heating element 30 facilitates heating in the cup body 10, and realizes the food breaking and heating at the same time.

[0059] The heating element 30 can be designed as a disc structure and arranged at the bottom of the necked portion 12. It should be noted that the end of the cutter head component 20 away from the heating element 30 can be located in the transition portion 13, i.e. the end of the cutter head component 20 away from the heating element 30 does not exceed the end of the transition portion 13 connected with the main body portion 11; or the end of the cutter head component 20 away from the heating element 30 can also be located outside the transition portion 13, i.e. the end of the cutter head component 20 away from the heating element 30 exceeds the end of the transition portion 13 connected with the main body portion 11.

[0060] Further, referring to Figure 4, the maximum value of the distance between the end of the cutter head part 20 away from the heating element 30 and the surface of the heating element 30 is denoted as h2, the distance between the end of the transition part 13 close to the main body part 11 and the surface of the heating element 30 is denoted as h1, and 75%≤h1 / h2≤100%. It can be seen that the end of the cutter head part 20 is beyond or flush with the end of the transition part 13 close to the main body part 11. Therefore, the ratio of h1 to h2 can be between 75% and 100%, such as but not limited to 75%, 80%, 85%, 90%, 95%, 100%, etc. By designing the ratio of the height of the end of the cutter head part 20 to the heating body and the height of the end of the transition part 13 close to the main body part 11 to the heating body to be between 75% and 100%, 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 cutter head part 20 includes a rotating shaft 21 and a plurality of blades 22 provided on the rotating shaft 21, the rotating shaft 21 is rotatably provided on the heating element 30, one end of each blade 22 connected with the rotating shaft 21 can be located in the closing part 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 part 13 close to the main body part 11. At this time, the distance h2 is the maximum value of the distance between the end of each blade 22 away from the rotating shaft 21 and the surface of the heating body.

[0062] When the inner wall of the main body part 11 is provided with the turbulence rib 14, one end of the turbulence rib 14 can extend to the transition part 13; or can be kept apart from the transition part 13 in the height direction X of the main body part 11. In some embodiments, the transition part 13 is provided with a notch 131, and the turbulence rib 14 extends into the notch 131 along the height direction X of the main body part 11. In addition, the distance between the end of the turbulence rib 14 away from the transition part 13 and the heating body is denoted as h3, and the distance between the limit line 111 in the main body part 11 and the heating body is denoted as h4, wherein h4≥h3.

[0063] To obtain the change of the simulated turbulent kinetic energy with the ratio of h1 to h2, the distance h3 can be taken as 112mm, at this time in the simulation software, the ratio of h1 to h2 is changed to obtain the corresponding turbulent kinetic energy, which can be specifically referred to Figure 6 . It can be seen from Figure 6 that the turbulent kinetic energy increases first and then decreases with the increase of the ratio of h1 to h2. 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 2Therefore, the homogenizer has high homogenizing performance.

[0064] It should be noted that, Figure 6 The broken line 3 in the figure refers to a broken line formed by linearly connecting each turbulent kinetic energy data line. Figure 6 The curve 4 in the figure refers to a curve fitted according to each turbulent kinetic energy data.

[0065] In addition, in order to make the purpose, technical scheme and advantages of the present application more concise and clear, the present application is described by the following specific examples, but the present application is not limited to these examples. The examples described below are only good examples of the present application, which can be used to describe the present application, and cannot be understood as limiting the scope of the present application. It should be noted that any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall 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 cutter head component 20 in the homogenizer to the inner diameter of the necked portion 12, i.e. the ratio of the diameter d1 to the inner diameter d2, is 63.6%; the ratio of the height of the one end of the cutter head component 20 from the heating body to the height of the one end of the transition portion 13 close to the main body portion 11 from the heating body, i.e. the ratio of h1 to h2, is 0%, i.e. there is no necked portion 12, and h1 is 0 mm. The specific operation steps are as follows:

[0067] 125 g of soaked wet beans were weighed and added to the cup body 10 of the homogenizer, and water was added to 1 L; the soybean milk function was started, and the rotating speed of the cutter head component 20 was controlled at 8000 rpm; after the whipping was completed, the soybean milk was poured into a 80-mesh screen and washed with clean water for 3 min; the screen was placed flat and left for 5 min to drain the clear water; the weight of the soybean milk wet residue was obtained by subtracting the weight of the screen. At the same time, the acoustic power noise of the homogenizer during operation was measured, which can be referred to Table 1.

[0068] In the example, the ratio of the diameter of the cutting profile 23 of the cutter head component 20 in the homogenizer to the inner diameter of the necked portion 12 is 70%; the ratio of the height of the one end of the cutter head component 20 from the heating body to the height of the one end of the transition portion 13 close to the main body portion 11 from the heating body is 75%. Since the specific operation steps of the example are consistent with those of the comparative example, they will not be repeated here, and the specific experimental data can be referred to Table 1.

[0069] Table 1

[0070] Number Blade diameter ratio Blade height ratio Rotation speed rpm Sound power noise dB Wall breaking rate (wet residue residual amount g) Comparative example 63.6% 0% 8000 72.3 28 Example 70% 75% 8000 69.1 14.5

[0071] Therefore, under the same cutter head component 20 and the same rotating speed, the ratio of the diameter of the cutting profile 23 of the cutter head component 20 to the inner diameter of the necked portion 12 is 70%, and the ratio of the height of the one end of the cutter head component 20 from the heating body to the height of the one end of the transition portion 13 from the heating body is 75%, compared with the scheme of the comparative example, the noise is reduced by 2dB, and the breaking rate is increased by nearly 1 times, and the breaking rate is significantly improved.

[0072] Further, please refer to Figure 4 The ratio of the distance h1 and the distance h2 also satisfies the condition: 75%≤h1 / h2≤85%. It can be known that the ratio of the distance between the transition portion 13 and the heating body and the distance between the cutter head component 20 and the heating body is further controlled between 75% and 85%, such as but not limited to 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 4%, 85%, etc. In this way, the ratio of h1 and h2 is further limited between 75% and 85%, and the breaking rate of the breaking machine is further improved.

[0073] In some embodiments, please refer to Figure 7 The application provides a breaking machine, which comprises a base 200, a driving member 300 arranged on the base 200, and a cup assembly 100 according to any one of the above, wherein the bottom of the cup body 10 is arranged on the base 200, and the driving member 300 is used to drive the cutter head component 20 to rotate around the axis thereof.

[0074] The breaking machine described above adopts the cup assembly 100 described above, and the inner diameter of the necked portion 12 is arranged to be smaller than the inner diameter of the main body portion 11, and the cutter head component 20 is located in the necked portion 12, which is beneficial to reduce 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 necked portion 12 is controlled between 65% and 85%, so that a suitable space is maintained between the cutter head component 20 and the necked portion 12, the turbulence intensity of the fluid around the cutter head component 20 is strengthened, the rate of the fluid circulating up and down between the main body portion 11 and the necked portion 12 is effectively promoted, and the cutting frequency of the cutter head component 20 is increased. Through the design, the cup assembly 100 improves the cutting frequency and the breaking rate by improving the structural design thereof, facilitates the realization of high breaking rate at a relatively low rotating speed, and further improves the load and noise problems caused by high rotating speed, and improves the user experience.

[0075] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.

[0076] The above embodiments only express several implementation ways of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation to the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
