[0003] At present, most products on the market use blades that are highly homogeneous straight blades or small-radius curved blades, and the blade structures of all blades are basically the same. This design mainly forms a single-direction axial or tangential flow field when running at high speed, which causes the material to be easily thrown to the cup wall and rotate with the cup, forming a stable "concentric vortex". This flow field causes a large amount of material to circulate in the cup inefficiently, making it difficult to be effectively pushed to the blades for crushing, thereby resulting in low crushing efficiency, uneven fineness, easy residue of large particles and other problems. In order to achieve the same crushing effect, the working time needs to be extended, which further puts higher requirements on the battery endurance when used outdoors. At the same time, the extension of the crushing time will further affect the fineness and uniformity of the juice.

DETAILED DESCRIPTION

[0021] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific embodiments, structures, features and effects according to the present application will be described in detail below in combination with the drawings and preferred embodiments.

[0022] Example 1: Reference​Figure 1 Figure 8 As shown in the drawings, the present application proposes a gap-adjustable fruit juice breaking machine. By the threaded connection of the cup cover 2 and the cup head 1 and the cooperation of the detachable part, the cup cover 2 is stably locked after being inverted to prevent liquid leakage. At the same time, the cup cover 2 can be taken off alone to be used as a drinking container, improving the convenience. Combined with the interference fit of the sealing ring 5 and the inclined surface structure, the sealing reliability is further enhanced, especially when the high-speed stirring or inverted pouring is still maintained good airtightness.

[0023] A gap-adjustable fruit juice breaking machine, comprising a cup head 1, a cup cover 2 and a blade assembly 3. The cup head 1 is internally provided with a groove, which is connected with the cup cover 2 through a thread to jointly form a crushing space. The blade assembly 3 comprises a driving motor 31 and a crushing part, wherein the driving motor 31 is located at the center position inside the cup head 1 and is connected with an electric control system (which is prior art) for controlling the start and stop of the driving motor 31. The crushing part is installed on the output shaft of the driving motor 31 and is located at the central axis of the crushing space; in addition, the crushing part is sequentially provided with an upper curved blade 32, an arc-shaped blade 33, a flat blade 34 and a lower curved blade 35 from top to bottom; when the cup head 1 is in an inverted state, the crushing space is filled with fruit material; after the cup head 1 is placed upright, the driving motor 31 is started to drive the crushing part to rotate and form a vortex in the crushing space. The vortex pushes the fruit material to rotate at high speed and gather to the crushing part, which is crushed by various blades. The crushed fruit material is thrown to the inner wall of the cup cover 2 under the action of centrifugal force, and then gathered to the crushing part area again under the drive of the vortex, repeating the above crushing process. Therefore, the fruit material continuously experiences the cycle of "gathering-crushing-diffusion" in the whole crushing process, thereby realizing efficient and uniform breaking effect.

[0024] Specifically, the cup head 1 is a double-layer structure divided into inner and outer layers, and an annular groove is arranged between the inner and outer layers, which divides the cup head 1 into two parts of the inner layer and the outer layer. The inner layer is higher than the outer layer, and the inner side of the outer layer is processed with a threaded groove. Figure 2 As shown in the drawings, the cup cover 2 is inverted groove-shaped, the upper segment and the lower segment have the same diameter, and the middle segment has a diameter larger than the upper and lower segments and is provided with a radial protrusion for convenient hand holding. The upper segment and the lower segment are smoothly transitioned with an arc surface, and the arc surface outside the lower segment and the middle segment is arrayed with a square groove, which is convenient for the user's fingers to put in, so as to conveniently apply a rotating force to the cup cover 2. The outer side of the lower segment is provided with an external thread which is threadedly connected with the threaded groove in the inner side of the outer layer of the cup head 1 to realize reliable sealing and jointly form a crushing space to ensure that the crushing space is leakproof in the upright or inverted state. The highest part of the inner layer of the cup head 1 is parallel to the highest part of the lower segment of the cup cover 2, and the highest part of the inner layer of the cup head 1 serves as the bottom of the crushing space.

[0025] ​Specifically, the upturned blade of the crushing piece is located at the uppermost position; it is mainly responsible for forming a downward vortex to pull the food materials on the upper part of the cup cover 2 downward to avoid the fruit materials floating on the top and being unable to be beaten; the arc-shaped blade 33 and the flat blade 34 are located in the middle part and are the main force of crushing; under high-speed rotation, they tear, cut and impact the fruit materials brought in by the vortex; the arc-shaped blade 33 is more suitable for processing fruit materials with more fibers, and the flat blade 34 produces stronger impact force; the lower upturned blade 35 is located at the lowermost position and is mainly responsible for forming an upward vortex to prevent particles from depositing at the bottom of the cup and ensure that all fruit materials circulate and be crushed multiple times to achieve no-dead-angle wall breaking.

[0026] Working principle: first, the cup head 1 and the cup cover 2 are in a separated and split state; when it is necessary to break the wall of the fruit materials and crush them into fruit juice, the user can refer to the following steps: Figure 4, the lower section (open end) of the cup cover 2 is upward, the fruit material is poured into the cup cover 2 groove space from the open end of the cup cover 2, then the annular groove of the cup head 1 is aligned with the lower section (open end) of the cup cover 2 for screw assembly, until the outer thread of the cup head 1 inner side and the outer thread of the cup cover 2 lower section are completely engaged, forming a sealed crushing space, at this time the fruit material is located in the inner groove space of the cup cover 2, the cup head 1 and the cutter head assembly are located above the fruit material, then the cup head 1 is turned to the upright state, the fruit material falls into the crushing element area under the action of gravity, the uppermost inner layer of the cup head 1 serves as the bottom of the crushing space, and the fruit material is placed in it. In addition, the outer side of the inner layer of the cup head 1 is attached to the lower section of the cup cover 2, and the gap between them is small, so that there is no leakage when it is inverted. The user starts the electric control system of the cup head 1, the electric control system starts the driving motor 31, the driving motor 31 drives the crushing element to rotate at high speed, under the joint action of centrifugal force and fluid dynamics, the cutter head assembly rotates at high speed to produce strong vortex phenomenon, which can cause particle circulation and homogenization. The crushing element is the core of turbulence, crushing and centrifugal force. Strong turbulence will make the juice crushed by the crushing element be thrown to the cup wall and move upward or downward along the cup wall, and then continue to flow back to the center cutter head area under the action of turbulence. Therefore, the crushing space formed by the cup head 1 and the cup cover 2 inside is a "high shear crushing zone", in which the flow velocity is fast and the shear force is strong, which is the core area of the broken juice particles. The core area is composed of a three-dimensional vortex field formed by the multiple blades of the crushing element, which flows from top to bottom and back to the center. The fruit material continuously rolls, collides and shears with the vortex, the upward blade 32 guides the top material to sink, the arc and flat blade 34 implements efficient crushing, and the downward blade 35 pushes the bottom particles to rise, forming a closed loop circulation, forming a strong circulating vortex circulation to suck and crush all fruit materials. Each cycle strengthens the crushing uniformity until the particles are as fine as paste. Turn off the motor, invert the cup head 1 again, the cup head 1 is in the upper position, and the cup cover 2 is in the upper position. The crushed juice gathers in the inner layer area of the cup cover 2 under the action of gravity, then the cup head 1 is rotated out of the open end of the cup cover 2, then the juice can be smoothly poured out of the open end of the lower section of the cup cover 2, and the drinking is convenient. The whole structure is quickly assembled and disassembled by mechanical screwing, and the precise thread sealing ensures the safety of use. In addition, through the mutual placement of the cup head 1 and the cup cover 2, the cup cover 2 can be used as a crushing container and directly as a drinking container. Compared with the existing cup cover 2 which is only used as a crushing container, the product portability and user experience are improved.

[0027] Example 2: The current juice breaking machine controls the speed and time of the crushing blade through the electric control system to control the crushing fineness. However, the precise control of the particle size of the juice is still insufficient. Because there is a nonlinear relationship between the rotating speed of the blade and the final fineness of the material particles, and the fruit type, water content and fiber structure difference have a great influence, the consistency of the paste particles is poor under the same speed mode.

[0028] To this end, on the basis of Embodiment 1, in Embodiment 2 of the present application, a detachable part is provided, through which the gap space and volume ratio of the "screening groove" and the "settling zone" can be actively adjusted, thereby regulating the size parameter and residence quantity of particles in the fruit juice. A gap groove is provided between the inner layer of the cup head 1 and the lower section of the cup cover 2. A containing groove 4 is opened on the inner layer of the cup head 1. A sealing ring 5 is sleeved on the containing groove 4. A detachable part is provided in the gap groove. The detachable part includes a clamping ring 6 and a sliding ring 7. The clamping ring 6 is detachably clamped to the inner layer of the cup head 1. The sliding ring 7 is slidably connected to the clamping ring 6. Specifically, a gap groove is further opened between the outer side of the inner layer of the cup head 1 and the inner side of the lower section of the cup cover 2. The gap groove is annular. An annular groove is opened on the outer side of the uppermost part of the inner layer of the cup head 1. The annular groove is in communication with the uppermost part of the gap groove. A convex ring is further provided at the lowermost part of the gap groove and slightly higher than the bottom surface of the outer side of the inner layer of the cup head 1. The convex ring protrudes only one third of the bottom surface of the outer side of the inner layer of the cup head 1. An embedded cavity is left between the bottom surface of the convex ring and the bottom surface of the outer side of the inner layer of the cup head 1. The embedded cavity is sleeved with the sealing ring 5. The sealing ring 5 is in the shape of an inverted T. The middle part of the sealing ring 5 is protruding. The inner side is sleeved into the embedded cavity. The outer edge of the sealing ring 5 is beveled. A beveled groove is further opened on the inner side of the lower section of the cup cover 2. The beveled groove cooperates with the beveled outer edge of the sealing ring 5, so that the inner side of the cup head 1 and the inner side of the cup cover 2 are sealed. In combination with the above-mentioned Embodiment 1, the inner side and the outer side of the cup cover 2 are sealed, which improves the sealing performance of the fruit juice and effectively prevents the residual liquid from penetrating into the threaded structure. During assembly, the cup head 1 drives the sealing ring 5 to rotate downward. The beveled surface of the sealing ring 5 contacts the beveled surface of the inner side of the lower section of the cup head 1 and applies radial pressure. The sealing ring 5 is elastically deformed to achieve interference fit. During disassembly, the cup head 1 is rotated in the opposite direction. The sealing ring 5 moves upward to release the pressure. The sealing ring 5 returns to its original state, which is convenient for separation. The operation is labor-saving and the repeated sealing performance is stable.

[0029] As described in Embodiment 1 above, the "high shear crushing zone" is formed in the crushing space composed of the cup head 1 and the cup cover 2. The strong circulating vortex circulation sucks all the fruit materials and breaks them. The gap groove serves as a "low flow rate buffer zone". The gap cavity is far away from the rotation center of the crushing part, so that the centrifugal force and shear force acting on the particles in the gap groove are weakened. In simple terms, after the particles enter the gap cavity, the probability of the particles temporarily "escaping" from the high-intensity crushing and entering a "buffering and staying" state is increased. The fruit particles stay in the gap groove, reducing the secondary addition of the fruit particles into the "high shear crushing zone" for crushing. Specifically, the fruit particles stay in the gap groove. Compared with the gear control of the blade speed and time to control the particle size of the crushed fruit juice in the prior art, there is a nonlinear relationship between the rotation speed of the blade and the final fineness of the material particles. The gap groove serves as a structure design that meets the "settling zone". The particle classification is naturally realized through the flow field distribution.

[0030] In addition, it should be noted that the above-mentioned gap groove is only a fixed space, which can only serve as a "settling area" to provide a low flow area for the crushing space. In order to improve the utilization rate of the gap groove, the clamping ring 6 and the sliding ring 7 are provided in the embodiment to make the space of the gap groove variable, so as to control the particle size and the amount of juice particles that stay, and to meet the needs of different consumers. The clamping ring 6 is made of a plastic metal part, specifically stainless steel. The clamping ring 6 is divided into multiple groups, and the thickness of the cup body of each group of sliding ring 7 corresponding to the clamping ring 6 is inconsistent. The thickness of the cup body of the clamping ring 6 changes the space of the gap groove, so as to realize the retention of different content of particle juice, Figure 8 Only three groups are shown, and in actual use, they can be produced according to demand. In addition, the inner convex ring on the upper end of the clamping ring 6 is fitted and attached to the inner layer of the cup head 1. The outer side of the upper end of the clamping ring 6 is an outer convex slope. The gap between the outer convex slope and the lower segment of the cup cover 2 serves as a screening groove, which relates to the quality of the juice particle size. The screening juice particles can enter the "settling area" (the size of the gap determines the parameters of the particles that can be settled). The ring body of the clamping ring 6 is located in the gap groove, and the inner side of the ring body is attached to the outer side of the inner layer of the cup head 1. The gap between the ring body of the clamping ring 6 and the lower segment of the cup cover 2 serves as a "settling area" space. The "settling area" (hereinafter referred to as the settling cavity) serves as a space for the juice particles to stay. The space of the settling cavity relates to the retention proportion of the particle size. When the bottom end of the clamping ring 6 is not clamped, it is in the shape of a ring (for reference Figure 8 The sliding ring 7 can be sleeved into the bottom end of the clamping ring 6. When the bottom end of the clamping ring 6 is clamped, the bottom end of the clamping ring 6 is extruded into an outer flared port by the slope between the convex ring upper surface and the inner layer of the cup head 1. The outer flared port is in the shape of a trumpet port, which realizes the limiting of the clamping ring 6, so that the cup head 1 will not fall under the action of gravity when it is upside down, and the clamping ring 6 is difficult to rotate in a ring shape through friction, ensuring stability. The sliding ring 7 is located between the outer convex slope and the bottom end of the clamping ring 6. The sliding ring 7 can slide axially along the outer side of the clamping ring 6. The inner side of the sliding ring 7 is an inclined surface and a ring surface. The inclined surface is attached to the outer flared port of the clamping ring 6, and the ring surface is attached to the ring body of the clamping ring 6. When the cup head 1 is upside down, the sliding ring 7 is located at the outer convex slope of the clamping ring 6 (for reference Figure 5 ), the inner side of the ring surface of the sliding ring 7 is located below. When the cup head 1 is placed horizontally, for reference Figure 7 , the sliding ring 7 is subjected to the action of gravity, and the inclined surface of the sliding ring 7 is located below and attached to the outer flared port of the clamping ring 6.

[0031] In assembly, according to the concentration of juice particles that the user wants to keep, different thicknesses of the snap ring 6 and the sliding ring 7 combination (different thicknesses of the snap ring 6 correspond to different diameters of the sliding ring 7) are used, then the cup head 1 is placed upright, the crushing piece is located above, the snap ring 6 is sleeved into the outer side of the inner layer of the cup head 1, the inner convex ring on the upper end of the snap ring 6 is sleeved and fitted on the ring groove on the outer side of the inner layer of the cup head 1, the bottom end of the snap ring 6 is extruded by the inclined surface between the upper surface of the convex ring and the outer side of the inner layer of the cup head 1 to form an outward flared mouth, forming a radial limiting and axial fixed self-locking structure of the snap ring 6, preventing the snap ring 6 from loosening or falling off during use. At this time, the sliding ring 7 slides down to the outward flared mouth along the outer side of the snap ring 6 under the action of gravity, its inner inclined surface is fitted with the outward flared mouth, and the side of the sliding ring 7 away from the sealing ring 5 is the bottom surface for storing juice particles. When the cup head 1 is placed upside down and the crushing piece is located below, the sliding ring 7 slides out of the outer convex inclined surface of the snap ring 6 under the action of gravity, and the stored juice particles fall into the groove space of the cup cover 2 under the action of gravity. The sliding ring 7 itself has a certain weight, and under the action of gravity, the sliding ring 7 accelerates to push the stored juice particles downward, at the same time, it also reduces the residue of juice particles outside the body of the snap ring 6. At this time, the sliding ring 7 and the snap ring 6 work together to ensure that the juice particles are smoothly discharged when inverted, avoiding blockage. At the same time, it ensures the thoroughness of particle discharge and the self-cleaning ability of the channel. The combination of different thicknesses of the snap ring 6 and the matching sliding ring 7 adjusts the width of the screening groove and the volume of the settling area, realizes personalized adjustment of the retention degree of juice particles, and meets the diverse drinking needs.

[0032] Therefore, by replacing different thicknesses of the snap ring 6 and matching diameters of the sliding ring 7, the gap groove volume can be accurately controlled to achieve graded control of the retention amount of juice particles, meeting diverse drinking needs. For example, when the settling cavity space is large: it can accommodate more particles, some of which will be recycled to the blade area, but most of which will stay in the cavity for a longer time, greatly reducing the proportion of secondary crushing - ultimately retaining "fruit particles that need to be chewed"; when the settling cavity space is small, the buffer area has a small capacity, and when the particle retention amount reaches a certain level, the remaining particles will be quickly pushed back to the blade area for continued high-intensity shearing and crushing - ultimately achieving the appropriate particle size. The screening groove acts as a "screen" to allow particles of a size that can enter the "settling area" to enter the "settling area". Users can achieve precise adjustment of the retention amount of particles by replacing the physical structure, and the cleaning is simple and convenient. At the same time, compared with the juicer with gear control blade speed and time, this mechanical control method avoids fluctuations in juice quality caused by unstable blade speed or time errors, making each extraction stable and controllable, and truly realizing the "selected is obtained" drinking experience. At the same time, the interference amount of the sealing ring 5 and the inclined surface of the cup head 1 ensures that a stable seal is formed every time the cup head 1 is tightened, making it leak-proof and stable for long-term use.

[0033] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application in any form. Although the present application has been disclosed with the preferred embodiments as above, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to obtain equivalent embodiments with equivalent changes, as long as the changes or modifications do not deviate from the technical solution of the present application.
