In addition, considering that the size of the magnetic region of the magnet 6 has a certain influence on the rotation speed of the juicing screw 4, the area S1 of the magnetic region on the disc surface of the magnet 6 is preferably 10cm2-200cm2In this way, the juicing screw 4 can be well driven to rotate by the magnetic region in this range, wherein the ratio S1/S2 of the area S1 to the overall area S2 of the disk surface 11 of the magnet 6 is 0 to 1, wherein when the ratio is 0, it indicates that the magnetic region on the "magnet 6" is 0, which is the magnetizer 7.

In addition, in order to further ensure the juicing rate and the effect of the juicing screw 4, the rated power P of the motor device 3 is 50W-1000W, preferably 120W-500W.
In addition, in any of the above magnetic driving structures of the juice extractor of the present invention, the motor device 3 may be an independent motor, that is, the magnet 6 or the magnetizer 7 is directly installed on the output shaft of the motor; alternatively, the motor means 3 may comprise a single motor and a corresponding power transmission system, such as a belt or gear system, i.e. the output shaft of the motor is drivingly connected to the belt or gear system, while the magnet 6 or the magnetic conductor 7 is arranged on the final output shaft of the belt or gear system.
Therefore, in view of the production cost and the light weight of the juicer, it is preferable that, as shown in fig. 1 and 2, the magnet 6 is directly fixed and sleeved on the output shaft 8 of the motor device 3, and the end surface 9 of the juicing screw 4 facing the mounting wall 5 is provided with the magnetizer 7 or the magnet 6, that is, the magnet 6 on the motor device 3 and the magnet 6 on the juicing screw 4 are separated from the mounting wall 5, or the magnet 6 on the motor device 3 and the magnetizer 7 on the juicing screw 4 are separated from the mounting wall 5; or, the output shaft 8 of the motor device 3 is directly and fixedly sleeved with the magnetizer 7, and the end surface 9 of the juicing screw 4 facing the installation wall 5 is provided with the magnet 6. Thus, when the motor device 3 operates, the juice extracting screw rod 4 is driven to rotate by the magnetic drive between the magnet 6 of the motor device 3 and the magnet 6 of the juice extracting screw rod 4 or the magnetic drive between the magnet 6 and the magnetizer 7, so as to realize juice extraction.
Of course, in the preferred embodiment, the magnet 6 or the magnetic conductor 7 may be directly disposed on the end surface of the juicing screw 4, for example, the magnet 6, preferably the magnetic conductor 7, may be integrally formed with the juicing screw 4, or may be ultrasonically welded together, or screwed together, or snapped together, or bonded together by an adhesive, etc.
Alternatively, in view of the connection reliability of the magnet 6 or the magnetic conductor 7 during the rotation of the juicing screw 4, it is more preferable that, as shown in fig. 1 and 2, an accommodating groove 10 is formed on the end surface 9 of the juicing screw 4, and the magnetic conductor 7 or the magnet 6 can be arranged in the accommodating groove 10 by any of the above-mentioned connection modes, so that the connection reliability during the rotation of the magnetic conductor 7 or the magnet 6 can be correspondingly improved by the limit action of the inner periphery of the accommodating groove 10 on the magnet 6 or the magnetic conductor 7.
Of course, in this case, in order to maintain the safety and hygiene of the juice, the magnetizer 7 or the magnet 6 may be provided with a sanitary-grade shield (not shown), such as a stainless steel layer or the like. Preferably, the protective layer and the end surface 9 remain flush.
Alternatively, the magnet 6 or the magnetic conductor 7 may be sealingly arranged inside the screw, for example, the magnet 6 or the magnetic conductor 7 may be arranged in a receiving recess 10 on the end surface 9 of the juicing screw 4, and then the cover is sealed by a cover (not shown), thereby further improving the safety and hygiene of the juice.
In addition, in the magnetic driving structure of the juicer according to the present invention, the magnet 6 may be specifically configured according to actual requirements, for example, the disc-shaped magnet 6 may be formed by a one-piece disc magnet, that is, the disc surface 11 of the magnet 6 is a magnetic area, so that the disc-shaped magnet can be accommodated in the positioning cylinder.
Alternatively, in view of the easy mounting assembly of the disc-shaped magnet 6 and the juicing screw 4 to the mounting wall 5, it is preferred that the magnet 6 comprises an inner annular magnetic ring 12 and an outer annular magnetic ring 13 arranged radially spaced apart as shown in figures 3-5, such that the central portion of the inner annular magnetic ring 12 may form a mounting hole for mounting with a protrusion on the mounting wall 5, wherein the region between the inner annular magnetic ring 12 and the outer annular magnetic ring 13 is a non-magnetic region 14. For example, more than two annular mounting grooves are coaxially formed radially outward on the end surface 9 of the juicing screw 4, and more than two annular magnets are arranged in the respective annular mounting grooves to form the magnet 6 including the inner annular magnetic ring 12 and the outer annular magnetic ring 13, it should be understood that the inner annular magnetic ring 12 and the outer annular magnetic ring 13 are not limited to be formed by a single annular magnet, for example, the inner annular magnetic ring 12 and the outer annular magnetic ring 13 may include one annular magnet and may also include 2 annular magnets.
In the preferred embodiment, further, the inner annular magnetic ring 12 and/or the outer annular magnetic ring 13 are continuously formed, for example, as shown in fig. 3, the inner annular magnetic ring 12 is continuously formed, that is, the magnetic region is continuous, as described above, it can be formed by one annular magnet or more than 2 annular magnets, and as shown in fig. 4, both the inner annular magnetic ring 12 and the outer annular magnetic ring 13 can be continuously formed, which can be selected according to actual requirements.
Of course, also in the preferred solution, alternatively, the inner annular magnetic ring 12 and/or the outer annular magnetic ring 13 are formed by a plurality of circumferentially spaced magnet pieces 18, as shown in fig. 3, the outer annular magnetic ring 13 is formed by a plurality of circumferentially spaced magnet pieces 18, and as shown in fig. 5, the inner annular magnetic ring 12 and the outer annular magnetic ring 13 are respectively formed by a plurality of circumferentially spaced magnet pieces 18, so that the number of magnet pieces 18 can be set accordingly according to the actual rotation speed requirement, thereby forming the required magnet 6.
In addition, in the magnetic driving structure of the juice extractor of the present invention, the magnetic field intensity of each magnetic region of the disc-shaped magnet 6 is the same in the radial direction, that is, the magnetism of the disc surface 11 of the entire magnet 6 is kept uniform to achieve stable and uniform rotation, for example, in the structure shown in fig. 3 to 4, the magnetic field intensity of the inner annular magnetic ring 12 and the outer annular magnetic ring 13 is the same;
alternatively or additionally, for increasing the rotational speed, the magnetic field strength of the outer magnetic region of the disc-shaped magnet 6 is optionally greater than the magnetic field strength of the inner magnetic region. For example, in the configuration shown in fig. 3 to 4, the magnetic field strength of the outer annular magnetic ring 13 is greater than that of the inner annular magnetic ring 12, so that when the disk is driven to rotate, the effect of the rotation speed obtained by the circumferential driving force applied to the outer region of the disk is greater than that of the circumferential driving force applied to the inner region of the disk, that is, the disk is more easily driven to rotate, and therefore, the magnetic field strength of the outer magnetic region of the disk-shaped magnet 6 is greater, so that the magnetic field force applied to the other magnet 6 or the magnetic conductor 7 is greater, so that the motor device 3 is more easily driven to rotate the juicing screw 4 when rotating.
In addition, in the magnetic driving structure of the juice extractor of the invention, the magnetic field generated by the operation of the motor device 3 does not influence the magnetic field of the magnet 6. However, if necessary, a magnetic field shield (not shown) is provided between the motor device 3 and the magnet 6 or the magnetic conductor 7 provided on the motor device 3, so that the stability of the magnetic field of the magnet 6 can be further improved.
Of course, similarly to the prior art, the magnetic driving structure of the juicer of the present invention may have a vertical type and a horizontal type, for example, as shown in fig. 2, the motor device 3 and the juicing screw 4 are coaxially arranged, wherein the motor device 3 and the juicing screw 4 are horizontally arranged to form a horizontal type juicer; alternatively, as shown in figure 1, the motor arrangement 3 juicing screw 4 is arranged vertically to form a vertical juicer.
At this time, in the vertical or horizontal type juicer, as described above, the juicing screw 4 may be rotatably assembled to the mounting wall 5 through various structural forms, such as a positioning cylinder, or, as shown in fig. 1 and 2, a cylinder 15 is extended from the mounting wall 5, a mounting groove 16 is formed on the end surface 9 of the juicing screw 4 facing the mounting wall 5, and the cylinder 15 is matched with the mounting groove 16, so that, by the alignment and matching of the cylinder 15 and the mounting groove 16 and the magnetic coupling, a magnetic force is applied during the installation, a user can easily and conveniently align the position, and the precise assembly of the juicing screw 4 is realized.
Of course, a corresponding wear resistant layer is formed between the cylinder 15 and the fitting groove 16 to improve the uniformity of rotation and prevent offset during rotation.
As is known, juice extractors are provided with a filter screen, as shown in fig. 1 and 2, outside the extractor screw 4 there is provided a filter screen 19.
Of course, the engagement between the post 15 and the fitting groove 16 can stably support the rotation of the juicing screw 4, but, in order to further improve the stability of the rotation, it is preferable that a support structure is also provided between the lid of the cup body 2 and the end surface of the juicing screw 4 opposite thereto, for example, a support pillar protruding from the lid and a receiving groove formed on the end surface of the juicing screw 4, the support pillar being located in the receiving groove to rotatably support the juicing screw 4. In this way, the two ends of the juicing screw 4 form supports, significantly improving stability.
