Description

Technical Field

[0001] The present invention relates to a juicer structure, and more particularly to a juicer for external use. Background Art

[0002] Juicers are developed based on conventional juicers. Compared to the high-speed speeds of conventional juicers, juicers use low-speed spiral extrusion technology. The lower the extrusion speed, the better. Typically, a juicer rotates at around 75 revolutions per minute, slowly squeezing out the juice like a towel. This process preserves the fruit's cellular structure and maintains its nutritional value. Furthermore, the low-speed juicing process doesn't generate high heat, preventing the juice from oxidizing due to heat.

[0003] Existing juice dispensers typically consist of a squeeze cup, a filter assembly, and a screw. The filter assembly also features an annular filter mesh. However, during R&D, it was discovered that significantly reducing the number of filter holes, or even creating only partial filtration, would not affect the filtration effect. Furthermore, the squeeze cup and filter assembly are typically separate, resulting in numerous components and cumbersome assembly. Furthermore, the existing structure requires a channel in the filter assembly for slag removal, further complicating the structure. Summary of the Invention

[0020] In the above-mentioned juice dispenser, the upper end of the sealing cover is hinged to the juice storage tank, and a mutually cooperating snap assembly is provided between the lower end of the sealing cover and the bottom of the juice storage tank.

[0021] In the above-mentioned juicer for juice delivery, the bottom cover is integrally formed with a mounting cylinder facing upward, the through hole is located at the bottom of the mounting cylinder, and the inner diameter of the mounting cylinder is larger than the inner diameter of the through hole.

[0022] A transmission assembly which can be extended and retracted along the axial direction of the installation cylinder is arranged in the installation cylinder, and the external motor power output shaft and the screw shaft are connected and linked through the transmission assembly.

[0023] In the initial state, the transmission assembly is correctly connected to the screw shaft. When the base of the built-in motor is assembled with the extrusion filter cup, if the motor power output shaft and the transmission assembly are not correctly connected, the transmission assembly is in a retracted state. When the motor drives the output shaft to rotate until it is correctly aligned with the transmission assembly, the transmission assembly is in an extended state.

DETAILED DESCRIPTION

[0044] Example 1

[0045] See Figures 1 to 10 As shown, a juicer for dispensing juice according to the present invention comprises a base 1 with a built-in motor. A squeeze filter cup 2 is detachably connected to the upper end of the base 1, and a screw 3 is disposed within the squeeze filter cup 2. A hopper 4 is disposed at the upper opening of the squeeze filter cup 2. The squeeze filter cup 2 comprises a cup body 2a that cooperates with the screw 3. A juice storage chamber 5 is integrally formed on the outer wall of the cup body 2a. A filter hole 2b is formed on the side wall of the cup body 2a corresponding to the juice storage chamber 5. A plurality of squeeze ribs 2c that cooperate with the screw 3 are evenly distributed circumferentially on the inner wall of the cup body 2a around the filter hole 2b. A juice outlet 2d is disposed on the outer wall of the juice storage chamber 5, and a juice outlet valve 2e is disposed on the juice outlet 2d.

[0046] A slag outlet 2f is provided on the side wall of the cup body 2a corresponding to the bottom of the extrusion gap formed by the cup body 2a and the screw 3. A slag outlet channel 2g is provided on the cup body 2a outside the outlet end of the slag outlet 2f, and a slag outlet valve 2h is provided in the slag outlet channel 2g.

[0047] A bottom cover 6 is detachably connected to the bottom of the cup body 2a, and the screw 3 is rotatably connected between the cup body 2a and the bottom cover 6; a through hole is provided on the bottom cover 6, and the motor power output shaft in the base 1 passes through the through hole and is connected to the rotating shaft of the screw 3.

[0048] In this embodiment, the silo 4 is detachably connected to the upper opening of the cup body 2a, a feed port is formed on the upper end surface of the silo 4, and a pushing rod 4a is inserted into the feed port.

[0049] The screw is installed from the bottom, so when disassembling and cleaning, it can be separated from the bottom cover first, and then the screw can be easily removed from the cup body. In the existing technology, the screw shaft is tightly connected to the sealing ring at the bottom of the cup body, which makes disassembly and assembly more inconvenient.

[0050] To facilitate assembly of the squeeze filter cup, the upper end of the base 1 is preferably provided with a positioning groove 1a adapted for the squeeze filter cup 2. This positioning groove 1a is also provided with a guide and stopper notch 1b adapted for the juice outlet 2d and the residue discharge channel 2g. During assembly, simply place the squeeze filter cup into the positioning groove, and the guide and stopper notch, the juice outlet, and the residue discharge channel mate to complete the assembly of the juicer, making operation very convenient.

[0051] Preferably, an installation chamber 4b is provided on the side wall of the silo 4, a limiting block 4c is provided at the bottom of the installation chamber 4b, and a through hole corresponding to the limiting block 4c is provided at the bottom of the installation chamber 4b; an elastic locking assembly 7 cooperating with the limiting block 4c is provided on the base 1.

[0052] When the base 1 and the squeeze filter cup 2 are in an assembled state, the outer bottom of the installation chamber 4b contacts the upper end surface of the base 1, and the elastic locking assembly 7 and the limiting block 4c cooperate to position the hopper 4.

[0053] The elastic locking assembly and the limit block cooperate to prevent the hopper from rotating and separating from the cup body during operation, thereby ensuring safety in use.

[0054] See Figure 5 As shown, in this embodiment, the elastic locking assembly 7 includes a limiting rod 7a that cooperates with the limiting block 4c, and a guide slope is provided at the upper end of the limiting rod 7a; a guide sleeve 7b is provided at the bottom of the limiting rod 7a, and a guide rod 7c is movably provided in the guide sleeve 7b.

[0055] A limiting hole 7d is axially symmetrically provided on the inner wall of the guide sleeve 7b, a limiting boss 7e matching the limiting hole 7d is integrally formed on the upper part of the guide rod 7c, and a first tensioning spring 7f is sleeved on the guide rod 7c on the upper side of the limiting boss 7e.

[0056] A clearance hole cooperating with the guide rod 7c is provided on the upper end surface of the base 1. In the initial state, the upper end of the guide rod 7c extends from the clearance hole under the action of the first tensioning spring 7f; when the silo 4, the cup body 2a and the base 1 are assembled, the limit block 4c is opposite to the vertical surface of the upper end of the guide rod 7c, and the silo 4 and the cup body 2a are in a fixed state that cannot be disassembled. When the silo 4 and the cup body 2a are detached from the base 1, the limit block 4c and the upper end of the guide rod 7c are separated, and the silo 4 and the cup body 2a are in a detachable state.

[0057] By setting up an elastic locking assembly, the hopper can only be rotated when the squeeze filter cup is separated from the base to complete the disassembly from the squeeze filter cup, ensuring safety in use.

[0058] Preferably, the bottom cover 6 is snap-fit ​​or threadedly connected to the cup body 2a, and a first sealing ring 8 is provided between the bottom cover 6 and the cup body 2a. In this embodiment, the bottom cover and the cup body are snap-fitted, and the specific snap-fitting method can adopt a conventional structure in the art, which will not be described in detail here.

[0059] Preferably, side slag retaining plates 2i are integrally formed on the outer walls of the cup body 2a on both sides of the slag outlet 2f, and bottom slag retaining plates 6a are integrally formed on the bottom cover 6 to cooperate with the side slag retaining plates 2i on both sides; when the bottom cover 6 and the cup body 2a are in an assembled state, the side slag retaining plates 2i and the bottom slag retaining plates 6a cooperate to form a slag discharge channel 2g;

[0060] Positioning buckles 2j that mate with the free ends of the bottom slag retaining plate 6a are hingedly connected to the side slag retaining plates 2i at the free ends of the slag discharge channel 2g. The positioning buckles ensure the tightness of the slag discharge channel and the stability of the assembly between the bottom cover and the cup body, ensuring that the bottom cover and the cup body do not rotate relative to each other during operation.

[0061] See Figure 7 As shown, in this embodiment, the juice storage chamber 5 is composed of a juice storage tank 5a integrally formed on the outer wall of the cup body 2a, a sealing cover 5b detachably connected to the opening of the juice storage tank 5a, and a second sealing ring 5c ​​sandwiched between the juice storage tank 5a and the sealing cover 5b; the sealing cover 5b is opposite to the filter hole 2b, and the juice outlet 2d is integrally formed on the sealing cover 5b.

[0062] Preferably, the upper end of the sealing cover 5b is hingedly connected to the juice reservoir 5a, and a cooperating snap assembly is provided between the lower end of the sealing cover 5b and the bottom of the juice reservoir 5a. The snap assembly can be any conventional structure in the art, as long as it allows for easy and clean assembly and disassembly of the sealing cover and juice reservoir. The hinged connection between the sealing cover and juice reservoir facilitates assembly.

[0063] Preferably, in this embodiment, the bottom cover 6 is integrally formed with a mounting tube 6 b upward, the through hole is located at the bottom of the mounting tube 6 b , and the inner diameter of the mounting tube 6 b is larger than the inner diameter of the through hole.

[0064] A transmission assembly 9 that can be extended and retracted along the axial direction of the installation tube 6 b is provided in the installation tube 6 b , and the external motor power output shaft and the screw rod 3 rotating shaft are connected and linked through the transmission assembly 9 .

[0065] In the initial state, the transmission assembly 9 is correctly connected to the rotating shaft of the screw 3. When the base of the built-in motor is assembled with the extrusion filter cup 2, if the motor power output shaft and the transmission assembly 9 are not correctly connected, the transmission assembly 9 is in a retracted state. When the motor drives the output shaft to rotate until it is correctly aligned with the transmission assembly 9, the transmission assembly 9 is in an extended state.

[0066] By providing a transmission assembly connecting the screw shaft and the motor output shaft on the base, the screw shaft can be connected to the motor output shaft without passing through the base, thus facilitating assembly and disassembly of the screw. Furthermore, the scalability of the transmission assembly further facilitates the connection between the screw shaft and the motor output shaft, and the transmission assembly enables adaptive correction of the connection between the screw shaft and the motor output shaft. In the prior art, the angle of the screw must be adjusted during assembly to ensure that the screw shaft and the motor output shaft are correctly aligned to complete the connection.

[0067] See Figure 9 and Figure 10 As shown, further preferably, the transmission assembly 9 includes a first transmission shaft 9a rotatably arranged in the installation cylinder 6b and matched with the rotating shaft of the screw 3, and an annular positioning cover 9b for positioning the first transmission shaft 9a is detachably connected to the opening of the installation cylinder 6b.

[0068] The first transmission shaft 9a is connected to a second transmission shaft 9c that cooperates with each other and can transmit radial torque. An axial elastic telescopic component 9d is connected between the first transmission shaft 9a and the second transmission shaft 9c to enable the first transmission shaft 9a and the second transmission shaft 9c to be displaced axially relative to each other.

[0069] Correspondingly, the first transmission shaft 9a includes a column 9e, an outer hexagonal connecting portion 9f adapted to the rotating shaft of the screw 3 is formed at the upper end of the column 9e, and a first inner four-corner connecting sleeve 9g coaxial with the column 9e and matched with the second transmission shaft 9c is integrally formed at the lower end of the column 9e, and a mounting through hole for conducting the first inner four-corner connecting sleeve 9g is formed on the column 9e along the central axis, and the axial elastic telescopic component 9d is located in the mounting through hole and connected to the second transmission shaft 9c.

[0070] The second transmission shaft 9c is composed of a second inner four-corner connecting sleeve 9h that matches the motor power output shaft and a guide column 9i that is integrally formed on the back of the second inner four-corner connecting sleeve 9h and is coaxial; the outer diameter of the guide column 9i is adapted to the inner diameter of the mounting hole; the axial elastic telescopic component 9d is connected between the mounting hole and the guide column 9i.

[0071] The axial elastic telescopic component 9d is composed of a positioning screw 9j and a second tensioning spring 9k; a limiting convex ring 9l is provided in the installation through hole to cooperate with the nut of the positioning screw 9j, and an internal screw hole 9m is formed axially at the upper end of the guide column 9i to cooperate with the positioning screw 9j, and the positioning screw 9j is threadedly connected to the internal screw hole 9m; the second tensioning spring 9k is clamped between the limiting convex ring 9l and the upper end of the guide column 9i.

[0072] In the initial state, the outer hexagonal connection part is correctly connected to the screw shaft. When the base of the built-in motor is assembled with the extrusion filter cup, if the motor power output shaft and the second inner four-corner connecting sleeve are not correctly connected, the second transmission shaft pushes up to put the tensioning spring in a contracted state. When the motor drives the output shaft to rotate to be correctly aligned with the second inner four-corner connecting sleeve, the second transmission shaft moves downward and resets under the action of the tensioning spring and puts the first transmission shaft and the second transmission shaft in a relatively fixed state, thereby ensuring normal transmission of the transmission assembly.

[0073] When in use, install the screw from the bottom of the cup body, then buckle the bottom cover with the cup body and rotate to position it. When installing the bottom cover, adjust the screw angle appropriately so that the outer hexagonal connection part is correctly connected to the screw shaft, then rotate the positioning buckle downward to buckle the free end of the bottom slag baffle, and the assembly of the cup body, screw and bottom cover is completed.

[0074] Next, connect the hopper and cup to form the upper assembly. Place the upper assembly into the positioning slots in the base, aligning the stoppers with the vertical surfaces at the upper ends of the guide rods. This completes the juicer assembly. Because the drive assembly is already included, alignment between the upper assembly and the base is not a concern.

[0075] During operation, the design of the transmission assembly prevents the upper body assembly from rising when juicing. At the same time, the assembly method of the upper body assembly and the base greatly facilitates the assembly of the entire juicer.

[0076] The juicer of the present invention is used in the same manner as the existing juicer. When cleaning, the bottom cover is opened and the screw can be easily removed.

[0077] Example 2

[0078] See Figure 11 As shown, the structure of the juicer of the present invention is basically the same as that of Example 1, except that the material bin 4 is integrally formed at the upper opening of the cup body 2a, a feed port is formed on the upper end surface of the material bin 4, and a pushing rod 4a is inserted at the feed port.

[0079] At the same time, the hopper and the cup body are eccentrically arranged so that the hopper discharge port is biased toward one side of the cup body. This is also a conventional structure in this field and will not be described in detail here.

[0080] Compared with Example 1, the silo and the cup body are integrally formed, which further saves the number of assembly parts and is more convenient for assembly and disassembly.

[0081] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the technical field can, without departing from the scope of the technical features of the present invention, make partial changes or modifications to the technical contents disclosed in the present invention and make equivalent embodiments without departing from the technical features of the present invention.
