Description

Technical Field

[0001] This utility model relates to the field of juicer technology, and specifically to a juicer. Background Technology

[0002] A slow juicer is developed from a conventional juicer. Its main purpose is to turn fruits and vegetables into juice to improve taste and make it convenient to drink. It includes a base with a built-in motor and a cup set on the base. The cup has an opening on one side and contains an upper pressing head and a lower pressing head with holes. The lower pressing head moves up and down driven by the motor to squeeze the fruits and vegetables located between the upper and lower pressing heads. The squeezed juice flows out from the holes and into the opening, and then into the cup placed outside.

[0003] The connection between the lower pressing head and the motor is such that the motor's drive rod is directly connected to a screw, and the bottom of the lower pressing head has a connecting sleeve that is threaded to the screw. Therefore, the lower pressing head, connecting sleeve, screw, and motor are basically on the same straight line, resulting in a relatively high overall height. Furthermore, it doesn't make good use of the space inside the base, as seen in the utility model with patent number 2016200798529. Alternatively, to reduce height, the motor can be placed on one side, and a gear set can be used to connect the motor to the bottom of the screw. While this reduces the motor's height and utilizes other space inside the base, the gear set structure still increases the overall height, as seen in the utility model with patent number 2021221236927. Summary of the Invention

[0004] The purpose of this invention is to provide a juicer that reduces the height of the motor by not aligning it with the lower pressing head. Furthermore, the motor is positioned horizontally on the inner side of the top of the base and is coupled with a worm gear. The worm gear is connected to the upper end of the external gear via a worm wheel and gear set. Since the top heights of the worm gear and the screw are approximately the same, the overall height is not increased. Therefore, this invention solves the problem of increased overall height caused by the structure between the motor and the screw.

[0005] The purpose of this utility model is achieved as follows:

[0006] A juicer includes a base and a lower juicer head disposed on the base, wherein the base has a built-in screw, and the lower juicer head has several holes and is connected to a connecting shaft.

[0007] The bottom of the connecting shaft passes through the base and is located inside the base. The end of the connecting shaft inside the base is an external gear. The external gear is sleeved on the outside of the screw and threadedly connected to the screw. A gear set is connected to the upper end of the external gear.

[0008] The base has a built-in motor, which is horizontally positioned on the inner side of the top of the base. The motor is connected to a worm gear, which is connected to a worm wheel. The worm wheel and a gear in the gear set are on the same shaft. The motor drives the worm gear to rotate, which in turn drives the gear set to rotate, which in turn drives the external gear to rotate. The external gear is connected to the screw via a threaded connection, which drives the external gear to move up and down, which in turn drives the lower press head to move up and down.

[0009] Preferably, the base includes a base plate and a top cover disposed on the base plate, and a placement frame is disposed on the inner side of the top of the top cover. The placement frame has a motor built in it, and the two ends of the connecting shaft pass through the placement frame and protrude.

[0010] Preferably, the placement rack is provided with a cover, and the cover has an opening corresponding to the connecting shaft. The outer side of the cover and the outer side of the placement rack are respectively provided with mounting part one and mounting part two. Fasteners pass through mounting part one and mounting part two and are inserted into the top cover, thereby connecting the cover and the placement rack and being placed on the inner side of the top cover.

[0011] Alternatively / and, the worm gear and the external gear are connected by a gear set, and the gear set is mounted on the mounting frame.

[0012] Preferably, the connecting shaft includes a mounting shaft and an external gear, with a connecting part at the top of the external gear, and the bottom of the mounting shaft is sleeved on the outside of the connecting part, and fasteners connect the bottom of the mounting shaft and the connecting part.

[0013] Preferably, the connecting part is provided with locking blocks on both sides, and the bottom of the mounting shaft should have locking blocks with locking grooves.

[0014] Preferably, limit switch one and limit switch two are respectively provided on one side of the upper and lower ends of the external gear.

[0015] Preferably, the base has a built-in circuit board 1, which is electrically connected to the motor. The placement rack is positioned above the circuit board 1, with its bottom abutting against the top of the circuit board 1. A support plate is provided on one side of the circuit board 1 at the bottom of the placement rack.

[0016] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0017] This invention reduces the height of the motor by not aligning it with the lower pressing head. Furthermore, the motor is positioned laterally and located on the inner side of the top of the base, in conjunction with a worm gear. The worm gear is connected to the upper end of the external gear via a worm wheel and gear set. As a result, the top heights of the worm gear and the screw are approximately the same, thus not increasing the overall height. Attached Figure Description

[0035] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0036] like Figures 1-8 As shown, a juicer includes a base 1 and a lower pressing head 2 disposed on the base 1. The base 1 has a built-in screw 60, and the lower pressing head 2 has a plurality of holes 21, and the lower pressing head 2 is connected to a connecting shaft 4.

[0037] Meanwhile, the bottom of the connecting shaft 4 passes through the base 1 and is located inside the base 1. The end of the connecting shaft 4 inside the base 1 is an external gear 41, which is sleeved on the outside of the screw 60 and threadedly connected to the screw 60. The upper end of the external gear 41 is connected to a gear set 7. Furthermore, the base 1 houses a motor 10, which is horizontally positioned inside the top of the base 1. The motor 10 is connected to a worm gear 20, which is connected to a worm wheel 90. The worm wheel 90 and one of the gears in the gear set 7 are located on the same shaft.

[0038] The gear set 7 is divided into three groups: a single large gear, a combination of a large and a small gear, and a single small gear. The combination of a large and a small gear is connected by a shaft, with the small gear located on top. At the same time, the single large gear meshes with the small gear in the combination gear, and the single large gear is connected to the upper end of the external gear 41. The single small gear meshes with the large gear in the combination gear, and the single small gear is located on the same shaft as the worm gear 90.

[0039] Therefore, in actual use, the motor 10 drives the worm gear 20 to rotate, which in turn drives the worm wheel 90 to rotate, which in turn drives the gear set 7 to rotate, which in turn drives the external gear 41 to rotate. Through the threaded connection between the external gear 41 and the screw 60, the external gear 41 moves up and down, which in turn drives the lower press head 2 to move up and down.

[0040] Therefore, this utility model reduces the height of the motor 10 by not setting the motor 10 and the lower pressing head 2 on the same straight line. Moreover, the motor 10 is set horizontally and located on the inner side of the top of the base 1, and is matched with the worm gear 20. The worm gear 20 is connected to the upper end of the external gear 41. That is, the top height of the worm gear 20 and the screw 60 are about the same, so the overall height dimension will not be increased.

[0041] Secondly, the juicing principle and structure of the juicer: This utility model also includes a barrel body 8, an upper pressing head 9, and an upper cover 3. The barrel body 8 is provided with a baffle 85, and the lower pressing head 2 is located above the baffle 85. The top of the connecting shaft 4 passes through the baffle 85 and is connected to the lower pressing head 2. Moreover, an outlet 84 is provided on one side of the barrel body 8, and a rotatable flip cover 83 is provided at the outlet 84.

[0042] Meanwhile, the bottom of the upper pressing head 9 is located inside the cylinder body 8, and the top of the upper pressing head 9 is connected to the upper cover 3.

[0043] Furthermore, the lower press head 2 is provided with a storage groove 1 corresponding to the upper press head 9, and a protrusion 24 is provided in the storage groove 1. The upper press head 9 is provided with a storage groove 25 corresponding to the protrusion 24. At the same time, the protrusion 24 and the storage groove 25 are respectively provided with a convex strip 22 and a convex strip 91.

[0044] Therefore, in actual use, the fruit and vegetables are limited in height by the storage groove 295 and the protrusion 24, and as the lower pressing head 2 moves upward, it is squeezed to extract juice by cooperating with the protrusion 22 and the protrusion 91. In addition, the operation of the motor 10 also requires the power supply 80 and the control of the circuit board 50.

[0045] Moreover, as Figures 2-3 As shown, the structure of circuit board 50 is as follows: First, the base 1 contains circuit board 50 and a placement rack 5. Circuit board 50 is electrically connected to motor 10. The placement rack 5 is used to place motor 10 and is positioned above circuit board 50. The bottom of placement rack 5 abuts against the top of circuit board 50. A support plate 52 is provided on one side of circuit board 50 at the bottom of placement rack 5.

[0046] Furthermore, circuit board 1 50 is equipped with a switch 501, and base 1 is equipped with a movable pressing plate 502 corresponding to switch 501. Circuit board 2 70 is built into base 1, and circuit board 2 70 is equipped with a charging interface. Base 1 is equipped with a sealing piece corresponding to the charging interface. Circuit board 2 70 is electrically connected to circuit board 1 50 and motor 10 respectively.

[0047] like Figures 6-8 As shown, the structure between the upper pressing head 9 and the base 1 and the cylinder body 8 is detachable, which facilitates cleaning and maintenance: First, a slider 81 is provided on the inner wall of the cylinder body 8, and a groove 92 is provided on the outer side of the upper pressing head 9, and a protrusion 93 is provided in the groove 92.

[0048] Therefore, in actual use, when connecting, the slider 81 moves in the groove 92 and matches the protrusion 93 to achieve connection. When separating, the slider 81 and the protrusion 93 are separated and the slider 81 is slid out of the groove 92.

[0049] Meanwhile, a slider 82 is provided on the inner wall of the cylinder body 8, and a groove 13 is provided on the outer side of the base 1, with a protrusion 14 provided in the groove 13.

[0050] Therefore, in actual use, when connecting, the slider 81 moves in the groove 92 and matches the protrusion 93 to achieve connection. When separating, the slider 81 and the protrusion 93 are separated and the slider 81 is slid out of the groove 92.

The outer side of the cover 6 and the outer side of the placement rack 5 are respectively provided with mounting part 1 61 and mounting part 2 51. Fasteners pass through mounting part 1 61 and mounting part 2 51 and are inserted into the top cover 12, thereby connecting the cover 6 and the placement rack 5 and being placed on the inner side of the top cover 12.

[0056] The fastener is a screw, and in order to ensure that the screw passes through, a protrusion and groove structure is used between the mounting part 1 61 and the mounting part 2 51 for initial positioning.

[0057] Secondly, the placement rack 5 and the cover 6 can be protected by the structure of the placement rack 5, and the gear set 7 is set on the placement rack 5.

[0058] like Figures 1-5 As shown, the connecting shaft 4 includes a mounting shaft 42 and an external gear 41. The mounting shaft 42 and the external gear 41 can be integrated or separate. When they are separate, the top of the external gear 41 is provided with a connecting part 411, and the bottom of the mounting shaft 42 is sleeved on the outside of the connecting part 411. Fasteners connect the bottom of the mounting shaft 42 and the connecting part 411, wherein the fasteners are screws.

[0059] In order to make the connection more stable and to ensure that the screw passes through, a locking block 412 is provided on both sides of the connecting part 411, and a locking groove 421 is opened on the bottom of the mounting shaft 42 by the locking block 412. The connection is achieved and the initial positioning is also achieved by the matching of the locking groove 421 and the locking block 412.

[0060] Meanwhile, the connecting shaft 4 is fitted with a first mounting ring 43 and a second mounting ring 44, both of which have grooves on their outer sides. The baffle 85 has an opening for the connecting shaft 4 to pass through, and the inner wall of this opening is provided with a third protrusion, which is located within the groove of the first mounting ring 43.
