Description

Technical Field

[0001] The present invention relates to the technical field of juicers, and specifically to a manual juicer.

Background Art

[0002] As the attention to health foods and organic agricultural products increases, it is becoming increasingly common for ordinary households to squeeze and drink the juice of vegetables and fruits on the spot. A juicer is a machine that can quickly squeeze fruits and vegetables into fruit and vegetable juice, and is mainly divided into two types: electric and manual, depending on the power. Manual juicers are suitable for household use because of their simple structure, compact size, safety, energy saving, and easy cleaning.

[0021] Hereinafter, the present invention will be described in more detail with reference to the drawings.

[0022] This specific embodiment is merely an explanation of the present invention and does not limit the present invention. After reading this specification, those skilled in the art can make modifications that do not contribute creatively to this embodiment as needed, but as long as they are within the scope of the utility model registration claims of the present invention, they will all be protected by the utility model law.

[0023] As shown in FIGS. 1 to 8, this embodiment relates to a manual juicer characterized by including a juicer main body 100, a rotating tray 200, a first juicing head 300, a second juicing head 400, a driving handle 500, and a transmission structure 600.

[0024] In the juicer main body 100, a juicing tray 131 is provided at the upper end of the juicer main body 100. The rotating tray 200 is rotatably provided on the juicing tray 131, whereby the rotating tray 200 can rotate within the juicing tray 131. A juicing head is attached above the rotating tray 200, and the juicing head can rotate together with the rotating tray 200. The driving handle 500 is provided on one side of the juicer main body 100, and the transmission structure 600 is provided inside the juicer main body 100. One end of the transmission mechanism is connected to the driving handle 500, and the other end is connected to the rotating tray 200, whereby power is transmitted from the driving handle 500 to the rotating tray 200. When the driving handle 500 is rotated, the rotating tray 200 is rotationally driven by the transmission mechanism, whereby the juicing head on the rotating tray 200 is rotationally driven. Then, fruits can be pushed against the rotating juicing head to be squeezed to obtain juice, and the squeezed juice flows into the juicing tray 131.

[0025] In this embodiment, the juice extraction head includes a first juice extraction head 300 and a second juice extraction head 400. The first juice extraction head 300 is attached to the central part above the rotating tray 200 and is rotatable together with the rotating tray 200. The size of the second juice extraction head 400 is larger than that of the first juice extraction head 300, and the second juice extraction head 400 is removably attached to the outer peripheral side of the first juice extraction head 300 above the rotating tray 200. When the second juice extraction head 400 is attached to the rotating tray 200, the first juice extraction head 300 is inserted into the second juice extraction head 400. At this time, in order to squeeze large fruits into juice, the juice extraction mode by the second juice extraction head 400 is used. When the second juice extraction head 400 is removed, the first juice extraction head 300 is exposed outside. At this time, in order to squeeze small fruits into juice, the juice extraction mode by the first juice extraction head 300 is used. By attaching and detaching the first juice extraction head 300, and by switching between the first juice extraction head 300 and the second juice extraction head 400 for use, fruits of various sizes can be squeezed into juice, which has excellent compatibility. Of course, in another embodiment, three or more juice extraction heads may be provided, and the plurality of juice extraction heads are inserted in sequence.

[0026] As a preferred form, in order to lock the second juice extraction head 400 to the rotating tray 200, a locking mechanism is provided between the rotating tray 200 and the second juice extraction head 400, thereby ensuring that the second juice extraction head 400 is stably attached to the rotating tray 200, and avoiding the second juice extraction head 400 from falling off when using the second juice extraction head 400 to extract juice, which may have an adverse impact on the experience of using the juice extractor.

[0027] In this embodiment, mounting holes 210 are provided on the circumferential side of the rotating tray 200, and mounting blocks 410 that fit with the mounting holes 210 are provided on the circumferential side of the bottom of the second juice extraction head 400. Through the insertion and fitting of the mounting holes 210 and the mounting blocks 410, the detachable mounting of the second juice extraction head 400 and the rotating tray 200 is realized. The mounting structure is simple, and the user can easily attach and detach the second juice extraction head 400 to switch and use the juice extraction head. As a preferred form, a plurality of sets of mounting blocks 410 are provided and evenly distributed on the circumferential side of the bottom of the second juice extraction head 400. Correspondingly, a plurality of sets of mounting holes 210 are also provided corresponding to the mounting blocks 410. The second juice extraction head 400 is mounted through the fitting of the plurality of sets of mounting holes 210 and the mounting blocks 410, ensuring the mounting stability across its circumferential side.

[0028] In this embodiment, a reverse locking hook 420 is provided on the mounting block 410, and a locking block 220 that fits with the reverse locking hook 420 is provided in the mounting hole 210. When it is necessary to attach the second juice extraction head 400 to the rotating tray 200, when the mounting block 410 is inserted into the mounting hole 210, the reverse locking hook 420 of the mounting block 410 is locked to the locking block 220 in the mounting hole 210. Thereby, the mounting block 410 is locked in the mounting hole 210, realizing the locking and fixing of the rotating tray 200 and the second juice extraction head 400, and avoiding the detachment of the second juice extraction head 400 during attachment and use. By pushing the second juice extraction head 400 laterally to slightly deform the second juice extraction head 400, the reverse locking hook 420 can be separated from the locking block 220, releasing the lock between the rotating tray 200 and the second juice extraction head 400, and facilitating the removal of the second juice extraction head 400 from the rotating tray 200.

[0029] In one preferred embodiment, the transmission structure 600 includes a transmission rod 610 and a transmission bevel gear 620. One end of the transmission rod 610 is connected to the drive handle 500, and the other end is connected to the transmission bevel gear 620. A rotating shaft 134 is provided on the juice extraction tray 131. The rotating tray 200 is rotatably mounted on the juice extraction tray 131 via the rotating shaft 134. A transmission ring gear 230 is circumferentially provided at the bottom of the rotating tray 200. The transmission ring gear 230 meshes with the transmission bevel gear 620, so that power is transmitted from the transmission structure 600 to the rotating tray 200. The transmission structure 600 rotationally drives the rotating tray 200, further rotates the juice extraction head, and performs the juice extraction operation.

[0030] Specifically, in this embodiment, a first bush 240 is provided at the central portion of the rotating tray 200. The first bush 240 is externally fitted onto the rotating shaft 134 to realize the connection between the rotating tray 200 and the rotating shaft 134. The rotating tray 200 is rotatably mounted on the juice extraction tray 131. A second bush 310 is provided at the bottom of the first juice extraction head 300. By externally fitting the second bush 310 onto the first bush 240, the connection between the first juice extraction head 300 and the rotating tray 200 is realized, and the first juice extraction head 300 can rotate together with the rotating tray 200. In one preferred embodiment, the rotating shaft 134 is configured in the shape of a hexagonal prism. The first bush 240 and the second bush 310 are correspondingly provided, so that the rotating tray 200 and the rotating shaft 134, and the first juice extraction head 300 and the rotating tray 200 can rotate synchronously, and no relative slippage occurs during the rotation process, which will not affect the use experience of the juice extractor.

[0031] In one preferred form, the juicer is provided on the front side of the juicer main body 100 and further includes a ball knife 800 for cutting the pulp of fruits (such as oranges, coconuts, etc.). A transmission shaft 810 is provided at the rear end of the ball knife 800. In the ball knife 800 for cutting the pulp, a transmission shaft 810 is provided at the rear end of the ball knife 800. The transmission shaft 810 extends into the interior of the juicer main body, and its end is removably connected to the transmission structure 600. Thereby, the power of the drive handle 500 is transmitted to the ball knife 800. Since the transmission shaft 810 is removably connected to the transmission structure 600, when the ball knife 800 is not needed, the ball knife 800 can be removed. Thereby, the appearance of the juicer can be kept clean and beautiful, and the risk of safety caused by the exposure of the ball knife 800 to the outside can be prevented. In this embodiment, since the ball knife 800 is made of a metal material, the efficiency of the ball knife 800 for cutting the pulp is enhanced, and the effect is made better. A connection hole 630 is provided at the end of the transmission rod 610 away from the drive handle 500. At the end of the transmission shaft 810, a connection block 820 that fits with the connection hole 630 is provided. Through the insertion and fitting of the connection block 820 and the connection hole 630, the removable attachment of the transmission mechanism and the transmission shaft 810 is realized. Thereby, the power from the transmission structure 600 to the transmission shaft 810 is transmitted, and a good use effect of the ball knife 800 is ensured.

[0032] In this embodiment, the juicer main body 100 includes a chuck base 110, a lower housing 120, and an upper housing 130. The chuck base 110 can stably fix the juicer main body 100 on the table by means of a chuck, ensuring the stability of the entire juicer during use. The lower housing 120 is detachably attached to the chuck base 110, and the upper housing 130 is detachably attached to the lower housing 120. The detachable structure of each part makes it easier to clean the juicer main body. The juice extraction tray 131 is provided on the upper housing 130, and a juice collection tray 123 is provided on the lower housing 120. A plurality of filtration holes 132 are provided at the bottom of the juice extraction tray 131. Thus, when the juice squeezed by the juice extraction head falls into the juice extraction tray 131, foreign matters such as pulp are filtered out onto the juice extraction tray 131 through the filtration holes 132 at the bottom of the juice extraction tray 131, and the juice falls into the juice collection tray 123. Preferably, a juice discharge port 121 is provided on one side of the juice collection tray 123, and the bottom of the juice collection tray 123 is inclined towards the juice discharge port 121 side. At the bottom of the juice collection tray 123, the side away from the juice discharge port 121 is higher than the side close to the juice discharge port 121. Thereby, the juice in the juice collection tray 123 flows towards the juice discharge port 121, facilitating the collection of the juice.

[0033] In one preferred form, a lock buckle 122 is provided on the peripheral side of the lower housing 120, and a lock block 133 corresponding to the lock buckle 122 is provided on the upper housing 130. By fitting the lock buckle 122 and the lock block 133, the upper housing 130 is locked to the lower housing 120, ensuring the stability of the entire juicer and achieving a good juice extraction effect.

[0034] The above is only used for explaining the technical solution of the present invention and is not restrictive. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention shall all be included in the scope of the claims for utility model registration of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
