The invention provides a juicing assembly and a juicer, wherein the juicing assembly is used for the juicer.

In an embodiment of the present invention, as shown in fig. 1, the juicer 1000 includes a support base 200, a motor assembly 300 and a juicer assembly 100.

As shown in fig. 1, the support base 200 generally includes a base 210 and a support column 220 connected to the base 210, the base 210 is used for being placed on a carrier such as a table or a cooking bench, and the support column 220 extends vertically. The base 210 includes a tapping platform 2110 located on one side of the support column 220, the tapping platform 2110 extending away from the support column 220. Of course, the structure of the supporting base 200 is not limited to this, for example, the base 210 may not include the juice extracting platform 2110. It should be noted that the present invention is not limited to the structure of the supporting seat 200, and a general structure of the supporting seat 200 is described herein for convenience of explaining the inventive concept of the present invention.

Wherein the motor assembly 300 is mounted to the support base 200. Specifically, the motor assembly 300 is mounted within the support column 220.

As shown in fig. 1, the motor assembly 300 includes a motor (not shown) and an output shaft 310, and it is understood that the output shaft 310 may be a motor shaft of the motor, or a driving shaft drivingly connected to the motor shaft through a transmission assembly (e.g., a gear assembly, etc.).

As shown in fig. 1, the output shaft 310 extends transversely, and the extending direction of the output shaft is the same as the extending direction of the juice extracting platform 2110, so as to output power to the juice extracting assembly 100.

As shown in fig. 1, the juice extracting unit 100 extends transversely and in the same direction as the juice extracting platform 2110. The juicing assembly 100 includes a transversely extending screw 60 that extends in the same direction as the juicing platform 2110.

As shown in fig. 1, the juicing assembly 100 is detachably mounted on the supporting base 200, and the screw 60 of the juicing assembly 100 is detachably connected with the output shaft 310 in a transmission manner. The transmission connection means that the output shaft 310 can transmit rotation to the screw 60 to rotate the screw 60 for juicing. Specifically, the juicing assembly 100 is removably mounted to the support column 220.

In this manner, by detachably mounting the juicing assembly 100 to the support base 200, the juicing assembly 100 can be conveniently detached for cleaning and the like.

Of course, in other embodiments, the output shaft 310 and the juice extracting assembly 100 may be integrally disposed vertically or obliquely, and the juice extracted by the juice extracting assembly 100 may be drained through the corresponding structure.

For the convenience of describing the present invention, the following description will be given mainly taking as an example that the output shaft 310 and the juicing assembly 100 integrally extend in the lateral direction.

Further, as shown in fig. 1, 4, 5 and 6, the juice extracting assembly 100 further includes a main cylinder 1, the main cylinder 1 includes a juice extracting cylinder 20 and a feeding cylinder 30 with an open end, the screw 60 is rotatably disposed in the juice extracting cylinder 20, and the juice extracting cylinder 20 is provided with a liquid outlet 21; the feeding cylinder 30 is connected to one side of the juice extracting cylinder 20 and is communicated with the juice extracting cylinder 20. Wherein the feeding cylinder 30 is integrated with the juicing cylinder 20.

Specifically, when the juice extracting assembly 100 is mounted on the support base 200, the juice extracting drum 20 extends laterally in the same direction as the juice extracting table 2110. The feeding cylinder 30 is optionally located on the upper side of the juice extracting cylinder 20, can extend in the vertical direction, and can be obliquely arranged on the upper side of the juice extracting cylinder 20, and the opening at one end of the feeding cylinder is the material inlet.

It will be appreciated that the juicing barrel 20 has two ends, one end of which is located close to the support column 220 and the motor assembly 300 and can be referred to as the rear end, and the other end of which is located away from the support column 220 and the motor assembly 300 and can be referred to as the front end; accordingly, the rear end of the juicing assembly 100 is adapted to be mounted to the support column 220, and the front end thereof is located away from the support column 220 and the motor assembly 300.

The liquid outlet 21 may be disposed at the lower side of the juice extracting barrel 20, that is, the liquid outlet 21 and the feeding barrel 30 are disposed at two opposite sides of the juice extracting barrel 20 respectively, so as to facilitate liquid outlet. Of course, in other embodiments, the outlet 21 may be disposed on a side of the juicer cartridge 20 facing the user or away from the user, and directed through a drain tube or a downwardly extending drip nozzle, etc.

When the juicer 1000 is in operation, materials can be put into the feeding cylinder 30 from the opening above the feeding cylinder 30 to enter the juicing cylinder 20 through the feeding cylinder 30, and at the same time or then, the motor assembly 300 drives the screw 60 to rotate in the juicing cylinder 20 through the output shaft 310 of the motor assembly to squeeze the materials in the juicing cylinder 20, so as to realize juicing, and the squeezed juice flows out through the liquid outlet 21.

In a specific embodiment, the juice extracting barrel 20 can be made into a barrel body with an opening at one end, and the screw 60 extends into the juice extracting barrel 20 through the opening; it can also be designed as a cylinder with two open ends, and the screw 60 extends into the juice extracting cylinder 20 through one of the open ends.

In a preferred embodiment, the two ends of the juice extracting tube 20 are open, so that the main tube 1 has a three-open tubular structure.

So, when washing, in the main barrel 1 is got into fast to the clear water accessible is uncovered to can be fast with the residue in the main barrel 1 from other uncovered outflow/take out, because uncovered (radial dimension) is great, it can not cause and block, can realize washing fast, can realize "cross the mesh that can wash totally of water. Or, when soaking and washing, clear water accessible three uncovered quick entering main barrel 1 to can dissolve the residue in the main barrel 1 fast, thereby when taking out or rocking main barrel 1 from the aquatic, the residue can flow out main barrel 1 along with rivers fast, in order to realize quick washing, can realize "can the sanitization's purpose cross a water".

Moreover, when the inner wall of the main cylinder 1 is adhered with residues which are difficult to clean (if the residues are dried after being forgotten to be cleaned after use), the brush can easily extend into the main cylinder 1 from any opening due to the large opening (radial size), so that the cleaning difficulty can be reduced.

That is to say, be uncovered setting through the both ends that make juicing barrel 20, can make main barrel 1 be the tubular structure that the three-terminal all is uncovered setting to make things convenient for rivers to get into fast or flow main barrel 1 when wasing, thereby can reduce the washing degree of difficulty, realize quick washing.

Hereinafter, the description will be given mainly by taking an example of "the juice extracting tub 20 is provided with both ends open".

Specifically, the openings at the two ends of the juice extracting cylinder 20 are respectively a first opening and a second opening. It is understood that the first opening may be the front opening of the juice extracting cylinder 20 and the second opening may be the rear opening of the juice extracting cylinder 20, and the second opening may be the front opening of the juice extracting cylinder 20 and the first opening may be the rear opening of the juice extracting cylinder 20. For convenience of explanation, the following description will mainly use "the second opening is the front opening of the juice extracting drum 20, and the first opening is the rear opening of the juice extracting drum 20" as an example.

Further, as shown in fig. 1 and 4, the juice extracting assembly 100 further includes a first cover 40 and a second cover 50, the first cover 40 is detachably mounted at the first opening, and the second cover 50 is detachably mounted at the second opening.

Specifically, the first cover 40 may be mounted at the first opening through a detachable connection structure such as a snap-fit structure, and a sealing structure (e.g., a sealing ring) may be disposed at the first opening to prevent liquid leakage; similarly, the second cover 50 can be mounted at the second opening by a detachable connection structure such as a snap-fit structure, and a sealing structure (e.g., a sealing ring) can be provided at the second opening to prevent leakage. The present invention does not limit the above sealing structure, as long as sealing is achieved.

In this way, the first cover 40 and the second cover 50 can be detached during cleaning.

The first cover 40 can be selected as a rear cover, and the second cover 50 can be selected as a front cover.

In particular embodiments, one end (i.e., the front end) of the screw 60 may be rotatably mounted to the first cover 40, and/or the other end (i.e., the rear end) of the screw 60 may be rotatably mounted to the second cover 50. In this manner, the screw 60 may be rotatably mounted within the juice extractor barrel 20. It is also possible to make one end (i.e., the front end) of the screw 60 not mounted to the first cover 40, and to make only it penetrate the first cover 40 and be drivingly connected to the output shaft 310 so as to be supported by the output shaft 310.

In a preferred embodiment, as shown in fig. 1-3, one end (i.e., the front end) of the screw 60 can be rotatably mounted on the first cover 40, and the other end (i.e., the rear end) of the screw 60 can be rotatably mounted on the second cover 50. Thus, the two ends of the screw 60 can be respectively fixed and supported by the first cover 40 and the second cover 50, so that the screw 60 can be prevented from swinging during rotation, the movement stability of the screw 60 during rotation can be improved, and abrasion can be reduced.

Hereinafter, the description will be given mainly taking an example of "both ends of the screw 60 are rotatably attached to the first cover 40 and the second cover 50, respectively".

Further, as shown in FIGS. 1, 4 and 5, the inner diameter of the juicer cartridge 20 is at least partially tapered along the length of the juicer cartridge 20.

In particular, the inner diameter of the juice extractor 20 is at least partially tapered in a direction from the rear end to the front end. It will be appreciated that in operation, the screw 60 rotates to drive material (fruit or vegetables, etc.) entering the juicer cartridge 20 from the rear end to the front end of the juicer cartridge 20, such that by providing the juicer cartridge 20 with an at least partially reduced internal diameter in the direction from the rear end to the front end, the material is progressively squeezed by the internal wall of the juicer cartridge 20, thereby improving juicing efficiency and effectiveness.

Of course, in other embodiments, the screw 60 may be rotated to drive the material (fruit or vegetables, etc.) entering the juicer cartridge 20 from the front end to the rear end of the juicer cartridge 20 when the screw 60 is activated, such that the inner diameter of the juicer cartridge 20 is at least partially tapered in a direction from the front end to the rear end. In the following description, the inner diameter of the juice extracting barrel 20 is at least partially reduced in the direction from the rear end to the front end, which is taken as an example to avoid redundancy.

In a specific design, the inner diameter of the juice extracting tube 20 may be reduced in the longitudinal direction of the juice extracting tube 20. The inner diameter of the juice extracting tube 20 can also be partially reduced in the length direction of the juice extracting tube 20, for example, the inner diameter can be unchanged and then reduced; alternatively, it may be unchanged, reduced, and then unchanged; or, for example, may be reduced first and then unchanged; alternatively, again, for example, one may first go constant, then fast taper, and then slow taper; and so on.

Specifically, the inner side surface of the tapered portion of the juice extracting tube 20 may be tapered, and the taper degree may be used to indicate the reduction degree (which indicates the reduction amount of the inner diameter per unit length in the longitudinal direction).

Further, as shown in fig. 1, 4 and 5, the diameter or equivalent diameter of the first opening is larger than the diameter or equivalent diameter of the second opening, and the ratio of the diameter or equivalent diameter of the second opening to the diameter or equivalent diameter of the first opening is greater than or equal to 0.1, such as 0.15, 0.2, 0.25, 0.35, 0.4, 0.45, 0.5, 0.55, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9 or 0.95. Thus, the juice extracting barrel 20 can be a barrel body with a small opening at the front end and a large opening at the rear end.

Optionally, the diameter or equivalent diameter of the second opening is in the range of 5mm-50mm, such as 10mm, 20mm, 25mm, 30mm, 35mm, 40mm or 45 mm.

It can be understood that if the ratio is too small, on one hand, the reduction amplitude is too large, and the material is not easy to extrude; on the other hand, the second opening is easy to be too small, which is not beneficial to cleaning.

Optionally, the ratio of the diameter or equivalent diameter of the second opening to the diameter or equivalent diameter of the first opening may be greater than or equal to 0.5 and less than or equal to 0.9; such as 0.55, 0.65, 0.7, 0.75, 0.8, or 0.85, etc.

Alternatively, the diameter or equivalent diameter of the second opening may be made to range from 16mm to 45 mm; for example, 20mm, 25mm, 30mm, 35mm or 40mm can be adopted.

Further, as shown in fig. 1, 4 and 5, the juice extracting barrel 20 may include a gentle feeding section 22 and an accelerated juice extracting section 23 connected in a length direction of the juice extracting barrel 20, an inner diameter of the accelerated juice extracting section 23 is reduced in the length direction of the juice extracting barrel 20, the first opening is provided in the gentle feeding section 22, the second opening is provided in the accelerated juice extracting section 23, and the feeding barrel 30 is connected to a side of the gentle feeding section 22.

In this manner, material may enter the flat entry section 22 through the entry cylinder 30 and be squeezed from the flat entry section 22 toward the accelerated juicing section 23, thereby further juicing in the accelerated juicing section 23.

It is understood that the accelerated juice extraction section 23 may be a section with the same deceleration, or may include a plurality of sections with different deceleration.

Specifically, the liquid outlet 21 is disposed at the smooth feeding section 22, so that the juice generated in the accelerated juice extracting section 23 can flow back to the smooth feeding section 22 and flow out from the liquid outlet 21.

Specifically, the inner side surface of the juice extracting tube 20 is provided with a convex edge extending along the length direction, so that on one hand, the juice extracting effect can be improved, and on the other hand, the materials can be prevented from sliding freely in the juice extracting tube 20.

Further, as shown in FIGS. 1, 4 and 5, the inside diameter of the flat feed section 22 is constant along the length of the juicer cartridge 20; alternatively, the inner diameter of the flat feeding section 22 is reduced in the length direction of the juice extracting barrel 20, and the reduction range of the flat feeding section 22 is smaller than that of the accelerated juice extracting section 23. Thus, the feeding effect can be ensured.

Accordingly, as shown in fig. 1, 4 and 12, the screw 60 may include a feeding section 62 and a squeezing section 63, wherein the pitch of the screw thread of the feeding section 62 is greater than the pitch of the screw thread of the squeezing section 63, the feeding section 62 is provided in the smooth feeding section 22, and the squeezing section 63 is provided in the accelerated juice extracting section 23. In this way, more material can be conveniently collected in the gentle feeding section 22, and the juicing effect can be ensured/improved in the accelerated juicing section 23.

Furthermore, the juice extracting barrel 20 is further provided with a residue discharging structure, for example, a residue discharging through hole (for example, the residue discharging through hole can be arranged on the accelerated juice extracting section 23) is directly arranged on the side wall of the juice extracting barrel 20, or a residue discharging gap 24 is arranged on the periphery of the second opening, and the like.

Thus, the residue after juicing can be discharged from the residue discharging structure.

In an alternative embodiment, as shown in fig. 1, 3, 4, 5, 7, 8 and 9, the tapping structure may be a tapping notch 24, i.e. the periphery of the second opening is provided with a tapping notch 24.

Specifically, the second cover 50 includes a bottom cover plate 51, and the slag notch 24 and the bottom cover plate 51 enclose to form a slag hole. When the screw 60 is operated, the residue is discharged from the slag hole at the front end along with the pushing of the screw 60 because of the non-flowability.

So, through set up slag notch 24 at the open periphery of second, can be convenient for wash slag notch 24 to prevent that the residue gathering is in slag tapping structure department. By forming the slag hole by surrounding the bottom cover plate 51 and the slag notch 24, the slag can be prevented from flying out from the opening side of the slag notch 24.

Further, as shown in fig. 5 and 7, the periphery of the slag notch 24 is provided with a slag surrounding plate 25, and the slag surrounding plate 25 and the bottom cover plate 51 are formed to surround a slag discharging channel communicated with the slag discharging hole. Thus, the residue can be discharged through the residue discharge channel to prevent the residue from flying around when being thrown out.

Specifically, the slag tapping enclosing plate 25 is arranged at the periphery of the slag tapping notch 24.

Further, as shown in fig. 8 and 9, the second cover 50 further includes a side cover plate 52 disposed on the periphery of the bottom cover plate 51, the side cover plate 52 is disposed outside the juice extracting barrel 20 and encloses with the juice extracting barrel 20 to form an annular gap 2; the side cover plate 52 is provided with a slag outlet 521 corresponding to the slag notch 24.

Specifically, the side cover plate 52 is disposed outside the juice extracting acceleration section 23, and surrounds the juice extracting acceleration section 23 to form the annular gap 2.

Thus, on one hand, the outer peripheral surface of the other end (i.e. the front end) of the juicing component 100 can be a flat (ring) surface, so that the practicability and the attractiveness are achieved; on the other hand, the annular gap 2 also receives the residue discharged from the slag discharge passage to prevent the residue from flying around. Also, the residue discharged from the slag discharging passage can be discharged through the slag outlet 521.

In particular, the side cover plate 52 can be detachably connected to the juice extracting tube 20, so that the second cover body 50 can be detachably mounted at the second opening.

Further, as shown in fig. 8 and 9, the outer side surface of the side cover plate 52 is provided with a slag trap 53 on the periphery side of the slag outlet 521. Specifically, the slag baffle 53 may be arranged around the slag outlet 521.

Thus, the residue can be prevented from flying around.

In this embodiment, the tapping notch 24 is located at an end (i.e. front end) of the juice extracting barrel 20 away from the supporting base 200 of the juice extractor 1000, i.e. the tapping notch 24 is located at a side of the juice extracting barrel 20 away from the supporting column 220/motor assembly 300. Therefore, the residue can be sent out from the front side of the liquid outlet 21, and the residue is convenient to recycle.

Optionally, one end (i.e., the front end) of the juicing assembly 100 projects out of the juicing platform 2110 in a direction away from the support column 220/motor assembly 300 to prevent debris from contaminating the juicing platform 2110.

Further, as shown in fig. 4, 5, 7 and 9, the area of the tap hole 24 is smaller than that of the tap hole 521. Therefore, the slag notch 24 can be prevented from being too large, so that excessive juice can be prevented from flowing out, and a large amount of residues can be prevented from being discharged quickly, so that the juice extracting effect is improved.

Further, as shown in fig. 4 and 9, the slag hole 521 has a first side edge and a second side edge which are opposite to each other in the rotation direction of the screw 60, and the slag notch 24 is disposed near the first side edge.

Thus, the accumulation of the residue at the slag notch 24 can be prevented, and the slag discharging effect can be improved.

Further, as shown in FIG. 8, the slag trap 53 includes a first slag trap side plate 531 (i.e., a front slag trap side plate), and an outer side surface of the first slag trap side plate 531 is coplanar with an outer side surface of the bottom cover plate 51. Thus, the second cover 50 can be easily placed to prevent rolling and can be easily cleaned.

In the embodiment, there are many ways to rotatably connect the other end of the screw 60 with the second cover 50, such as a connection via a thin shaft; the following examples are given.

Further, as shown in fig. 1, 3, 4 and 12, one of the end surface of the other end of the screw rod 60 and the inner side surface of the bottom cover plate 51 is provided with a limiting rotation hole 64, and the other end is provided with a limiting rotation protrusion 511, the limiting rotation protrusion 511 is rotatably installed in the limiting rotation hole 64, and the ratio of the diameter of the limiting rotation protrusion 511 to the diameter of the other end of the screw rod 60 is greater than or equal to 0.1, and may be 0.15, 0.2, 0.25, 0.35, 0.4, 0.45, 0.5, 0.55, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9 or 0.95, and the like.

Optionally, the diameter of the limiting rotation protrusion 511 ranges from 5mm to 50mm, such as 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm or 45mm, and the like.

Optionally, the ratio of the diameter of the limit rotation protrusion 511 to the diameter of the other end of the screw 60 is greater than or equal to 0.5, so that the limit rotation protrusion 511 is thicker, that is, the rotation shaft portion of the screw 60 rotatably connected to the second cover 50 is thicker, thereby increasing the sliding contact area, increasing the wear resistance, and preventing the screw 60 from shaking during rotation after long-term use. Thereby improving the rotational stability and the service life of the screw 60.

Further, as shown in fig. 1, 4 and 12, the ratio of the diameter of the limiting rotation protrusion 511 to the diameter of the other end of the screw 60 may be greater than or equal to 0.6 and less than or equal to 0.9, and may be 0.65, 0.7, 0.75, 0.8, or 0.85, for example. Therefore, not only can the wear-resisting area be enough, but also the limiting rotary bulge 511 can be prevented from being too thick.

Specifically, the limiting rotation hole 64 is formed in the end face of the other end of the screw rod 60, and the limiting rotation protrusion 511 is formed in the inner side face of the bottom cover plate 51, so that the structural strength of the bottom cover plate 51 at the limiting rotation protrusion 511 can be increased (for example, the thickness of the limiting rotation protrusion 511 can be increased, or a stepped structure is formed at the limiting rotation protrusion 511, etc., so as to increase the structural strength of the bottom cover plate 51 at the limiting rotation protrusion 511), and thus the impact resistance of the bottom cover plate 51 can be improved.

Wherein, the side wall of the limit rotating hole 64 forms an annular sliding projection 65.

As shown in fig. 1, 3, 4 and 12, the bottom cover plate 51 is further provided with a limiting ring wall 512 protruding from the limiting rotary protrusion 511 at an interval, an annular sliding groove 513 is formed between the limiting ring wall 512 and the limiting rotary protrusion 511, and the annular sliding protrusion 65 is rotatably installed in the annular sliding groove 513, so that the other end of the screw 60 is rotatably installed on the second cover 50.

Thus, wear-resistant surfaces can be formed on both sides of the annular sliding protrusion 65, so that wear resistance can be further enhanced. That is to say, when the device works, the annular chute 513 can limit both the inner side and the outer side of the annular sliding protrusion 65, when the screw 60 extrudes materials, the reverse acting force of the materials on the screw 60 can enable the inner ring side surface of the side of the annular sliding protrusion 65 close to the materials to abut against the inner side chute wall of the corresponding position of the annular chute 513, and simultaneously enable the outer ring side surface of the side of the annular sliding protrusion 65 far away from the materials to abut against the outer side chute wall of the corresponding position of the annular chute 513, so that the pressing action of the materials on the multiple screws 60 is favorably dispersed to the inner ring side surface and the outer ring side surface of the opposite side of the annular sliding protrusion 65, thereby being favorable for leading the pressing action force on the two opposite sides of the annular sliding protrusion 65 to tend to be balanced, avoiding the problem that the reverse acting force of the materials on one side of the screw 60 is concentrated on one side of the screw 60, and the pressing force between the screw 60 and the rotationally connected components is too large, the components are locally and the abrasion is further influenced by the stability and the service life of the rotationally connected components of the screw 60, thereby being beneficial to ensuring the stability of the juicing of the screw 60.

Meanwhile, the annular sliding protrusion 65 facilitates the screw rod 60 to be directly vertically placed on a desktop or a platform for drying after being cleaned, and avoids the screw rod 60 from rolling and falling off when being horizontally placed on the desktop or the platform, so that the screw rod 60 is convenient to dry.

Of course, in other embodiments, the structure of the annular sliding protrusion 65 and the annular sliding groove 513 may be designed in other manners, for example, the annular sliding protrusion 65 may be disposed on the inner side surface of the bottom cover plate 51, and the annular sliding groove 513 may be disposed on the other end surface of the screw 60; and the like.

Further, as shown in fig. 1, 3, 4 and 12, a receiving groove is formed at the second opening, and the limiting ring wall 512 is disposed in the receiving groove. Thus, the retaining ring wall 512 can be hidden and retained.

Further, as shown in fig. 1, 3, 4 and 12, the width of the annular runner 513 is at least partially reduced in the depth direction of the annular runner 513. Thus, installation can be facilitated.

Further, as shown in fig. 3 and 9, the protruding height of the limiting rotary protrusion 511 in the direction away from the bottom cover plate 51 is greater than the protruding height of the limiting ring wall 512 in the direction away from the bottom cover plate 51. Therefore, the assembly difficulty can be further reduced.

Further, as shown in fig. 3 and 9, a stopping convex portion 5111 is disposed on a side surface of the limiting rotation protrusion 511 away from the bottom cover plate 51, and the stopping convex portion 5111 is used for abutting against the bottom of the limiting rotation hole 64.

It can be understood that during the rotation of the screw 60, the other end of the screw 60 (i.e. the bottom of the rotation limiting hole 64) may abut against the bottom cover plate 51 (i.e. the side of the rotation limiting protrusion 511 away from the bottom cover plate 51), and the abutting area can be reduced by providing the abutting protrusion 5111, so as to reduce the friction force and reduce the power consumption.

Further, as shown in fig. 1, 4, 5 and 6, the juice extracting assembly 100 further includes a drip-preventing cover 80, the drip-preventing cover 80 being rotatably mounted on an outer side of the juice extracting barrel 20, the drip-preventing cover 80 having a first position for closing the liquid outlet 21 and a second position for opening the liquid outlet 21. Specifically, the anti-drip cover 80 may be switched between the first position and the second position by rotation.

Thus, by arranging the anti-dripping cover 80 at the liquid outlet 21, the anti-dripping cover 80 can be rotated to open the liquid outlet 21 when necessary, so as to realize juice outlet; when not needed, the anti-drip cover 80 can be rotated to close the liquid outlet 21, so that the anti-drip is realized.

Further, as shown in fig. 1, 4, 5 and 6, the outer side surface of the juice extracting barrel 20 is provided with a liquid outlet nozzle 26 at the liquid outlet 21, and the anti-drip cover 80 blocks the liquid outlet nozzle 26 when in the first position to close the liquid outlet 21; in the second position the spout 26 is opened to open the spout 21. Thus, by providing spout 26, on the one hand, dispensing is facilitated and, on the other hand, drip prevention cap 80 is also facilitated to open or close dispensing outlet 21.

Further, as shown in fig. 1, 4, 5 and 6, the outer side of the juice extracting barrel 20 is provided with a mounting projection 27, the mounting projection 27 is provided at one side of the liquid outlet nozzle 26, and the anti-drip cover 80 is rotatably mounted on the mounting projection 27. In this manner, the drip-proof lid 80 may be conveniently positioned at the same height as the spout of the spout 26 to facilitate closing of the spout 26.

Wherein the mounting protrusion 27 is integrally connected to the outlet nozzle 26.

Further, as shown in fig. 1, 4, 5 and 6, the installation convex portion 27 is provided with a rotating shaft 28, the anti-dripping cover 80 comprises a cover body 81 and a rotating portion 82 connected to one side of the cover body 81, the cover body 81 is used for blocking the liquid outlet nozzle 26, the rotating portion 82 is provided with a shaft hole, the rotating shaft 28 is rotatably installed in the shaft hole, so that the anti-dripping cover 80 is rotatably installed on the installation convex portion 27. Thus, the drip prevention cover 80 can be rotatably coupled to the mounting protrusion 27, and the structure is simple.

Specifically, the rotating shaft 28 and the shaft hole are in interference fit, or a rotary damper is arranged between the rotating shaft 28 and the shaft hole, so that the anti-dripping cover 80 is positioned at the first position and the second position.

Further, as shown in fig. 1, 4, 5 and 6, the rotation shaft 28 includes a first shaft portion 281 connected to an end of the mounting boss 27 away from the juice extracting barrel 20, and a second shaft portion 282 connected to the first shaft portion 281 and located at one side of the mounting boss 27; the rotating portion 82 includes a first rotating portion 821 and a second rotating portion 821 connected to each other in an axial direction, the first rotating portion 821 is provided with an avoidance gap (not shown) communicating with the shaft hole, the first rotating portion 821 is provided on the first shaft portion 281, and the second rotating portion 821 is provided on the second shaft portion 282.

Thus, the rotational stability can be improved.

Further, as shown in fig. 1, 4, 5 and 6, the drip-preventing cap 80 further includes a grip portion 83, and the grip portion 83 is connected to one side of the rotation portion 82. In this manner, the rotation of the drip prevention cover 80 can be driven by the grip portion 83. In the first position, the anti-drip cover 80 extends laterally, and in the second position, the anti-drip cover 80 is disposed vertically.

Further, one side of the anti-drip cover 80 for closing the liquid outlet 21 is provided with a sealing plug/gasket/sealing ring, and the outline of the sealing plug/gasket/sealing ring is greater than or equal to the outline of the liquid outlet 21.

Further, as shown in fig. 1, 2 and 11, the motor assembly 300 further includes a motor, an elastic member 90, and a connection sleeve 70 whose sleeve hole is a limiting structure for preventing circumferential rotation, the connection sleeve 70 is axially movably sleeved on the output shaft 310, and the connection sleeve 70 rotates with the output shaft 310 because the sleeve hole has the limiting structure for preventing circumferential rotation.

Wherein the elastic member 90 is used to make the connecting sleeve 70 have a tendency to move in a direction away from the motor along the axial direction.

When the juice extracting assembly 100 is mounted/assembled on the supporting base 200 (the supporting column 220), the connecting sleeve 70 is movably sleeved on one end (i.e. the rear end) of the screw 60 along the axial direction, so that the screw 60 is detachably connected with the output shaft 310 in a transmission manner through the connecting sleeve 70.

Wherein, since the sleeve hole of the connecting sleeve 70 has a limit structure for preventing circumferential rotation, it will transmit the power of the output shaft 310 to the screw 60 for the driver to rotate.

The sleeve hole is a rectangular hole, a pentagonal hole, a hexagonal hole, an elliptical hole, or a round hole with a limiting structure on the inner wall, and the like, and is not limited herein. It should be noted that the cross-sectional shape of the end of the output shaft 310 and the cross-sectional shape of the end of the screw 60 are adapted to the shape of the trepan to achieve the transmission connection.

It can be understood that, since the elastic member 90 makes the connecting sleeve 70 have a tendency to move in a direction away from the motor in the axial direction, when the juice extracting component 100 and the supporting seat 200 are assembled, one end (i.e. the rear end) of the screw 60 can be directly installed in place without considering the alignment of the screw 60 and the connecting sleeve 70, and in the process, the screw will press the connecting sleeve 70 to move backwards and move to an avoiding position, and the elastic member 90 stores energy; when the motor is turned on, the output shaft 310 is driven to rotate, so as to drive the connecting sleeve 70 to rotate, and after the connecting sleeve 70 is aligned with/aligned with one end (i.e. the rear end) of the screw rod 60, the connecting sleeve 70 moves forward under the driving of the elastic member 90 to a connecting position, so as to realize power transmission, which can realize quick and automatic alignment of the connecting sleeve 70 and the screw rod 60.

That is, during assembly, the connecting sleeve 70 has an avoiding position abutting against the screw 60 and a connecting position sleeved on the output shaft 310 and the screw 60 to connect the connecting sleeve 70 and the output shaft 310 in a transmission manner.

Thus, by arranging the elastic member 90 and the connecting sleeve 70 and enabling the connecting sleeve 70 to have an avoiding position and a connecting position through the elastic member 90, the alignment problem of the connecting sleeve 70 and the screw 60 does not need to be considered when the juicing assembly 100 and the supporting seat 200 are assembled, namely, the assembly is not influenced by the angle between the screw 60 and the trepanning, and the juicing assembly 100 and the supporting seat 200 can be rapidly assembled. After assembly, the screw 60 and the connecting sleeve 70 can be quickly and automatically aligned through motor driving, so that transmission connection is realized.

Further, a first gap is formed between the outer side surface of the output shaft 310 and the inner side surface of the connecting sleeve 70. The connection between the output shaft 310 and the connecting sleeve 70 can be semi-flexible, so that the problems of too fast abrasion caused by small deviation, easy breakage of the connecting position and the like in the transmission process can be avoided.

Further, a second gap is formed between the outer side surface of the screw rod 60 and the inner side surface of the connecting sleeve 70. Thus, on one hand, the connection between the screw rod 60 and the connecting sleeve 70 can be made to be semi-flexible, so that the problems of too fast abrasion caused by small deviation, easy breakage of the connecting position and the like in the transmission process can be avoided. On the other hand, after the connecting sleeve 70 is aligned with the screw rod 60, the connecting sleeve 70 is easily moved from the avoiding position to the connecting position, that is, the connecting sleeve 70 is easily sleeved on the screw rod 60.

In a specific embodiment, the sleeve hole may be a through hole to simplify the structure, and when the connecting sleeve 70 is located at the connecting position, one end of the output shaft 310 may extend into one side of the sleeve hole, and one end of the screw rod 60 may extend into the other side of the sleeve hole.

The trepan may be a stepped bore, and may include a first step bore and a second step bore, a cross-sectional area of the second step bore is larger than a cross-sectional area of the first step bore, the output shaft 310 may be movably installed in the first step bore in the axial direction, and one end of the screw 60 may be movably installed in the second step bore in the axial direction.

In this embodiment, the trepan boring is a through bore.

In a specific embodiment, the elastic member 90 can be a compression spring, or an elastic sheet, or a tension spring, or a rubber band, etc., as long as the connecting sleeve 70 has a tendency to move in a direction away from the motor along the axial direction.

In this embodiment, the elastic member 90 may be selected as a compression spring.

Further, as shown in fig. 1 and 2, the compression spring is sleeved outside the output shaft 310, one end of the compression spring is limited in the motor casing of the motor or the limiting structure in the supporting seat 200, and the other end of the compression spring is limited in the connecting sleeve 70, so that the connecting sleeve 70 has a tendency of moving in a direction away from the motor along the axial direction.

The limiting structure in the supporting seat 200 may be a bearing or a shaft sleeve of the output shaft 310, or a limiting protrusion or a limiting bracket in the supporting seat 200.

In this way, the connecting sleeve 70 can have the tendency of moving in the direction away from the motor along the axial direction through the action of the compression spring; moreover, the structure can be simplified, and the cost can be reduced.

Further, as shown in fig. 1 and 2, an abutting convex portion is provided on an outer side surface of the connection sleeve 70, and the other end of the compression spring is sleeved outside the connection sleeve 70 and abuts against the abutting convex portion. Thus, the other end of the connecting sleeve 70 can be limited.

Further, as shown in fig. 1 and 2, the supporting base 200 further includes a mounting base 230, the mounting base 230 is located at the output shaft 310, and the juice extracting assembly 100 is detachably mounted on the mounting base 230. Wherein the mounting base 230 is a portion of the support post 220.

Specifically, a first installation groove 2310 is formed in one side of the installation base 230 facing the motor assembly 300, an installation hole 2330 is formed in the bottom of the first installation groove 2310, a limiting protrusion 71 is formed on the outer side surface of the connection sleeve 70, and the connection sleeve 70 includes an insertion portion 72 located on one side of the limiting protrusion 71.

The limiting convex parts 71 may be annularly arranged, or a plurality of limiting convex parts may be annularly distributed.

Specifically, the connection sleeve 70 is movably installed in the first installation groove 2310, the insertion part 72 is movably installed in the installation hole 2330, and the other end of the screw rod 60 is sleeved in the insertion part 72; the limit protrusion 71 abuts against the bottom of the first installation groove 2310, so that the connection sleeve 70 is limited at a connection position.

Therefore, the movement of the connecting sleeve 70 can be limited, so that the connecting sleeve is limited at the connecting position.

It should be noted that the abutting convex part may be provided integrally with the limit convex part 71, that is, the same convex part/structure.

Further, as shown in fig. 1 and 2, a second mounting groove 2320 is formed on a side of the mounting base 230 away from the output shaft 310, and the juice extracting assembly 100 is detachably mounted in the second mounting groove 2320; the bottom of the second mounting groove 2320 is partially arched toward the side away from the output shaft 310 to form the first mounting groove 2310 on the side of the mounting base 230 facing the motor assembly 300. The mounting hole 2330 communicates the first mounting groove 2310 and the second mounting groove 2320.

Thus, the structure can be simplified.

Further, as shown in FIGS. 1 and 2, the juicer assembly 100 may be removably mounted to the mounting base 230 via a snap-fit arrangement. Thus, the juice extracting assembly 100 can be conveniently and simply assembled and disassembled.

Further, as shown in fig. 1, 4 and 12, the screw 60 includes a main body and a transmission shaft mounted on the main body, and the transmission shaft is detachably connected with the output shaft 310 through a connection sleeve 70.

That is, the rear end of the screw 60 is a transmission shaft, and the main body portion includes a feeding section 62 and an extruding-cutting section 63.

Wherein, the transmission shaft can be selected as a metal shaft.

Of course, in other embodiments, the screw 60 may be provided as a unitary structure.
