Description

Technical Field

[0001] This utility model relates to a juicer, and more particularly to a squeeze-type juicer. Background Technology

[0002] Currently, fruit is the main source of vitamins for the human body. Studies have shown that people who eat fruit regularly are healthier than those who don't like to eat fruit. In particular, fruit plays an irreplaceable role in disease prevention. To diversify the flavor of fruit, it can be juiced. Currently, juicing is usually done manually, but this requires the user to apply a lot of force to squeeze the juice, which is inefficient and laborious.

[0003] To address the aforementioned issues, automatic squeezing juicers have emerged on the market. For example, the squeezing structure disclosed in patent CN216317031U includes a mounting plate, a connecting device, and a squeezing device. The connecting device includes a first support rod, a second support rod, an electric push rod, and an upper crossbeam. The electric push rod passes through the top of the mounting plate and is installed on one side of the upper crossbeam. The squeezing device includes a squeezing seat and a squeezing head. The output end of the electric push rod is threadedly connected to the squeezing head through screws and nuts. The electric push rod pushes the squeezing head to move up and down to squeeze and extract juice.

[0004] The existing squeeze-type juicers have the following problems: their pressing heads are fixed by screws and nuts, and tools are needed to disassemble and clean the pressing heads after pressing, making disassembly and assembly quite cumbersome. Utility Model Content

[0005] Based on the problem that the pressing head is fixed by screws and nuts, and that disassembling and cleaning the pressing head after juicing requires tools and is relatively cumbersome, this utility model provides a squeeze-type juicer.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an extrusion juicer, including a frame, a pressing seat, a pressing head, and a displacement drive device. The pressing seat is disposed opposite to the pressing head below it. The pressing head is connected to the displacement drive device, which can drive the pressing head to move up and down relative to the frame. The displacement drive device is provided with a connecting part for connecting with the pressing head. The pressing head is detachably installed on the connecting part through a snap-fit ​​structure. When the pressing head is installed on the connecting part, it can rotate around a first axis on the connecting part to switch between a snap-fit ​​position and a release position.

[0007] When the pressing head rotates to the locking position, the pressing head is fixed relative to the connecting part along the extension direction of the first axis.

[0008] When the pressing head is rotated to the release position, the pressing head can move along the extension direction of the first axis to separate from the connecting part.

[0009] A further preferred embodiment of this utility model is as follows: the pressing head is provided with a groove for the connecting part to be inserted, the snap-fit ​​structure includes a limiting stop and a snap-fit ​​block corresponding to the limiting stop, the limiting stop is disposed on the inner side wall of the groove, the snap-fit ​​block is disposed on the connecting part, the pressing head is inserted into the connecting part through the groove and rotates, so that the snap-fit ​​block is snapped on one side of the limiting stop to restrict the movement and separation of the connecting part from the groove.

[0010] A further preferred embodiment of this utility model is as follows: the groove is circular, and an L-shaped protrusion is provided on the inner wall of the groove. The L-shaped protrusion includes a first protrusion and a second protrusion.

The end of the slot away from the second protrusion is provided with a first opening for the locking block to enter the slot. After the connecting part is inserted into the groove, the pressing head is rotated to make the locking block lock into the slot, restricting the movement and separation of the connecting part from the groove. The lower surface of the first protrusion serves as a limiting stop on one side of the locking block.

[0011] A further preferred embodiment of this utility model is as follows: the groove is circular, and an L-shaped groove is provided on the inner wall of the groove. The L-shaped groove includes a first groove segment and a second groove segment. The first groove segment extends circumferentially along the groove. One end of the second groove segment is connected to one end of the first groove segment. The other end of the second groove segment extends toward the groove opening and penetrates the upper edge of the groove sidewall, so as to form a second inlet on the upper edge of the groove sidewall for the locking block to enter the second groove segment. After the connecting part is inserted into the groove, the pressing head is rotated to make the locking block lock into the first groove segment to restrict the movement and separation of the connecting part from the groove. The upper surface of the first groove segment serves as a limiting stop edge that blocks the locking block on one side.

[0012] A further preferred technical solution of this utility model is as follows: the frame includes a base, two uprights and a crossbar. The two uprights are respectively erected vertically on the left and right sides of the base, and the crossbar is placed horizontally between the two uprights.

The gear is connected to the motor shaft of the motor. The rack is vertically arranged and meshes with the gear. The movable frame is movably mounted on the guide columns. The movable frame is fixedly connected to the rack. A connecting part is provided at the part of the movable frame above the pressing seat. The pressing head is detachably mounted on the connecting part. When the motor drives the gear to rotate, the rack drives the movable frame and the pressing head to move up and down relative to the frame along the guide columns.

[0016] A further preferred embodiment of this utility model is as follows: the displacement driving device is mounted on the frame and includes a motor, two lead screws, and a movable frame. The two lead screws are vertically arranged and respectively mounted on the left and right sides of the frame.

[0018] Compared with the prior art, the advantages of this utility model are that by setting a connecting part on the displacement driving device, the pressing head is detachably installed on the connecting part through a snap-fit ​​structure. When the pressing head is installed on the connecting part, the pressing head can rotate around the first axis on the connecting part to switch between the snap-fit ​​position and the release position. When the pressing head rotates to the snap-fit ​​position, the pressing head is fixed relative to the connecting part along the extension direction of the first axis. At this time, the pressing head is connected to the connecting part. When the pressing head rotates to the release position, the pressing head can move along the extension direction of the first axis to separate from the connecting part. This patent can disassemble the pressing head by rotating it from the snap-fit ​​position to the release position. During disassembly, it is only necessary to rotate and move the pressing head in the direction of the first axis. This makes the disassembly of the pressing head unnecessary for auxiliary tools, which is convenient for disassembly and cleaning after juicing, as well as installation after cleaning.

Detailed Implementation

[0046] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0047] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0048] Figures 1-25As shown, the squeeze-type juicer includes a frame 1, a pressing seat 6, a pressing head 5, and a displacement drive device 7. The pressing seat 6 is positioned below the pressing head 5 and is used to place the object to be squeezed, such as fruit. The pressing head 5 is connected to the displacement drive device 7, which drives the pressing head 5 to move up and down relative to the frame 1. When the pressing head 5 moves downward, it presses against the object placed on the pressing seat 6, squeezing the object to extract juice. By driving the pressing head 5 to extract juice through a drive structure, the juicing efficiency is improved by replacing manual labor with mechanical methods.

[0049] The displacement drive device 7 is provided with a connecting part 19 for connecting with the pressing head 5. The pressing head 5 is detachably installed on the connecting part 19 through a snap-fit ​​structure. When the pressing head 5 is installed on the connecting part 19, the pressing head 5 can rotate around the first axis 53 on the connecting part 19 to switch between the snap-fit ​​position and the release position. When the pressing head 5 rotates to the snap-fit ​​position, the pressing head 5 is fixed relative to the connecting part 19 along the extension direction of the first axis 53. When the pressing head 5 rotates to the release position, the pressing head 5 can move along the extension direction of the first axis 53 to separate from the connecting part 19.

[0050] This patent allows the pressing head 5 to be rotated from the locked position to the released position by rotating the pressing head 5, and then the pressing head 5 can be disassembled by moving it. This makes the disassembly of the pressing head 5 unnecessary for auxiliary tools, which is convenient for disassembly and cleaning after juicing, and for reassembly after cleaning.

[0051] Preferably, the pressing head 5 is provided with a groove 25 for the connecting part 19 to be inserted. The snap-fit ​​structure includes a limiting baffle 29 and a snap-fit ​​block 24 corresponding to the limiting baffle 29. The limiting baffle 29 is disposed on the inner side wall of the groove 25, and the snap-fit ​​block 24 is disposed on the connecting part 19. The pressing head 5 is inserted into the connecting part 19 through the groove 25 and rotates, so that the snap-fit ​​block 24 is snapped on one side of the limiting baffle 29. The limiting baffle 29 forms a block against the snap-fit ​​block 24 to restrict the pressing head 5 from moving relative to the connecting part 19 along the extension direction of the first axis 53, thereby restricting the connecting part 19 from moving and separating from the groove 25, so that the pressing head 5 is connected to the connecting part 19 for squeezing and juicing.

[0052] Figure 5 , Figure 13 , Figure 16 , Figure 21 , Figure 24As shown, in one specific embodiment of the snap-fit ​​structure, the groove 25 is circular, and an L-shaped protrusion is provided on the inner wall of the groove 25. The L-shaped protrusion includes a first protrusion 27 and a second protrusion 26. The first protrusion 27 extends circumferentially along the groove 25, and one end of the second protrusion 26 is connected to one end of the first protrusion 27. The other end of the second protrusion 26 extends towards the bottom of the groove 25 and connects to the bottom of the groove 25. The L-shaped protrusion and the bottom of the groove 25 combine to form a snap-fit ​​groove 28. The end of the snap-fit ​​groove 28 away from the second protrusion 26 has a first opening for the snap-fit ​​block 24 to enter the snap-fit ​​groove 28. During connection, the pressing head 5 is moved upward along the extension direction of the first axis 53 and fitted onto the connecting part 19 through the groove 25. During the upward movement, the L-shaped protrusion... The pressing head 5 is misaligned with the locking block 24, allowing it to move upwards to a position where the first opening is opposite to the locking block 24. Then, the pressing head 5 is rotated, causing the locking block 24 to enter the locking groove 28 from the first opening. During this process, the pressing head 5 rotates from its initial release position to the locking position. At this time, the first protrusion 27 is positioned above the locking block 24, thereby restricting the pressing head 5 from moving relative to the connecting portion 19 along the extension direction of the first axis 53, preventing the pressing head 5 from separating from the connecting portion 19. During disassembly, the pressing head 5 is rotated in the opposite direction, causing the locking block 24 to rotate out of the locking groove 28 and re-misalign with the L-shaped protrusion. During this process, the pressing head 5 rotates from the locking position to the release position. By moving the pressing head 5 downwards, it disengages from the connecting portion 19. The lower surface of the first protrusion 27 serves as a limiting stop 29 blocking one side of the locking block 24. When the connecting part 19 is inserted into the groove 25, the extending direction of the first axis 53 coincides with the central axis of the groove 25.

[0053] The number of L-shaped protrusions can be one or more. This patent does not limit the number. Preferably, there are three L-shaped protrusions. The three L-shaped protrusions are evenly arranged on the inner circumferential surface of the groove 25. The number of snap-fit ​​blocks 24 is the same as the number of L-shaped protrusions, and they are arranged in a one-to-one correspondence.

[0054] Preferably, after the locking block 24 enters the locking groove 28, the friction between the locking block 24 and the inner wall of the groove 25 can restrict the rotation of the pressing head 5 relative to the connecting part 19. Alternatively, by providing a locking groove on the locking block 24 and a corresponding protrusion in the locking groove 28, after the locking block 24 enters the locking groove 28, the elastic deformation of its own material after being squeezed by the locking block 24 and the protrusion will cause the protrusion to lock into the locking groove, thus restricting the rotation of the pressing head 5 relative to the connecting part 19.

[0055] Figure 25As shown, another specific embodiment of the snap-fit ​​structure is provided. The groove 25 is circular, and an L-shaped groove is provided on the inner wall of the groove 25. The L-shaped groove includes a first groove segment 51 and a second groove segment 52. The first groove segment 51 extends circumferentially along the groove 25. One end of the second groove segment 52 is connected to one end of the first groove segment 51, and the other end of the first groove segment 51 extends toward the groove opening of the groove 25 and penetrates the upper edge of the side wall of the groove 25, so as to form a second inlet on the upper edge of the side wall of the groove 25 for the snap-fit ​​block 24 to enter the second groove segment 52. During connection, the pressing head 5 is moved upward along the extension direction of the first axis 53 and is fitted onto the connecting part 19 through the groove 25. During the upward movement, the second opening is opposite to the snap-fit ​​block 24 on the connecting part 19, so that when the groove 25 is inserted upward into the connecting part 19... The locking block 24 enters the second groove 52 through the second opening and moves to the end where the second groove 52 connects to the first groove 51. Then, the pressing head 5 is rotated, causing the locking block 24 to move from the second groove 52 into the first groove 51. During this rotation, the pressing head 5 rotates from the initial release position to the locking position. At this time, the upper surface of the first groove 51 is limited above the locking block 24, thereby restricting the pressing head 5 from moving relative to the connecting part 19 along the extension direction of the first axis 53, preventing the pressing head 5 from moving relative to the connecting part 19 and separating. During disassembly, the pressing head 5 is rotated in the opposite direction, causing the locking block 24 to rotate out from the first groove 51 to the second groove 52. During this process, the pressing head 5 rotates from the locking position to the release position. By moving the pressing head 5 downward, the pressing head 5 is disengaged from the connecting part 19. The upper surface of the first groove 51 serves as a limiting stop 29 blocking one side of the locking block 24. The extension direction of the first axis 53 coincides with the central axis of the groove 25.

[0056] The number of L-shaped grooves can be one or more. This patent does not limit the number. Preferably, there are three L-shaped grooves. The three L-shaped grooves are evenly arranged on the inner circumferential surface of the groove 25. The number of snap-fit ​​blocks 24 is the same as the number of L-shaped grooves, and they are arranged in a one-to-one correspondence.

[0057] Preferably, after the locking block 24 enters the L-shaped groove, the friction between the locking block 24 and the inner wall of the L-shaped groove, or the friction between the connecting part 19 and the inner wall of the groove 25, can restrict the rotation of the pressing head 5 relative to the connecting part 19. Alternatively, by providing a locking groove on the locking block 24 and a corresponding protrusion on the first groove segment 51, after the locking block 24 enters the first groove segment 51, the elastic deformation of its own material after being pressed against the protrusion causes the protrusion to engage in the locking groove, thus restricting the rotation of the pressing head 5 relative to the connecting part 19.

[0058] The pressing seat 6 is mounted on the frame 1. The pressing seat 6 includes a funnel 32 and a vessel 30 disposed inside the funnel 32. The vessel 30 has a holding space and a filter hole 31. The filter hole 31 is used to filter the pressed liquid. When pressing is required, the object to be pressed is placed into the vessel 30, and then the displacement drive device 7 is activated. The displacement drive device 7 drives the pressing head 5 to move downward. The pressing head 5 squeezes the object placed in the vessel 30. The liquid produced by pressing flows into the funnel 32 after being filtered through the filter hole 31, and then flows out downward from the funnel 32. The user can place a carrying container under the funnel 32 to receive the liquid flowing out from the funnel 32.

[0059] The displacement driving device 7 has various structures, for example:

[0060] In one embodiment of the displacement drive device 7, the frame 1 includes a base 2, two uprights 3, and a crossbeam 4. The two uprights 3 stand vertically on the left and right sides of the base 2, respectively, and the crossbeam 4 is placed horizontally between the two uprights 3. The press seat 6 is mounted on the crossbeam 4. The displacement drive device 7 includes a motor 11, a drive shaft 14, two lead screws 18, and a movable frame 45. The base 2 has a receiving cavity 10, and the motor 11 and the drive shaft 14 are mounted in the receiving cavity 10. The drive shaft 14 is horizontally positioned and connected to the motor 11. The motor shaft is connected, and two lead screws 18 are vertically placed inside the two uprights 3. The lower ends of the two lead screws 18 are respectively connected to the left and right sides of the drive shaft 14. The left and right sides of the movable frame 45 are threadedly connected to the lead screws 18 on both sides. The movable frame 45 is provided with a connecting part 19 above the pressing seat 6. The pressing head 5 is detachably mounted on the connecting part 19. When the drive shaft 14 drives the lead screws 18 on both sides to rotate, the lead screws 18 drive the movable frame 45 to move up and down relative to the frame 1. By hiding the motor 11 and the drive shaft 14 inside the base 2, and hiding the two vertically placed lead screws 18 inside the uprights 3 on both sides, the transmission components between the motor 11 and the movable frame 45 are not exposed, and the overall structure is more aesthetically pleasing.

[0061] The bottom of the base 2 has an opening of the accommodating cavity 10. A gearbox 12 is installed in the accommodating cavity 10. The motor 11 is fixed on the gearbox 12. A gear set is installed in the gearbox 12. The motor shaft of the motor 11 is connected to the input end of the gear set. A mounting base 13 is fixed in the accommodating cavity 10. A transmission shaft 14 is installed on the mounting base 13 and can rotate around its own axis. The transmission shaft 14 is connected to the output end of the gear set. Two driving bevel gears 15 are fixed on the transmission shaft 14. Driven bevel gears 16 are installed on the lead screws 18 on both sides. The driven bevel gears 16 on the two lead screws 18 mesh with the two driving bevel gears 15 respectively, so that when the motor 11 drives the transmission shaft 14 to rotate, the transmission shaft 14 can drive the two lead screws 18 to rotate.

[0062] There are two specific structures for the juicer using the aforementioned displacement drive device 7.

[0063] Figures 1-6 As shown, in the first type, the upper end of the lead screw 18 is rotatably connected to the top of the upright 3, and the lower end of the lead screw 18 is rotatably connected to the base 2. An outer sleeve 17 is fitted over the lead screw 18, with the lower end of the outer sleeve 17 abutting against the base 2. The horizontal frame 4 has through holes 20 on both sides, through which the lead screws 18 on both sides pass. The horizontal frame 4 abuts against the upper ends of the outer sleeves 17 on both sides. The bottom of the horizontal frame 4 has a positioning protrusion corresponding to the outer sleeve 17, which is inserted into the outer sleeve 17 to restrict the relative movement of the outer sleeve 17 and the lead screw 18 in the radial direction of the lead screw 18. The upright 3 has a third opening along its height on its opposite sidewalls, including an upper opening 9 and a lower opening 8. The upper opening 9...
