[0002] Tomato seed extractors can be widely used in food processing, cosmetics manufacturing, pharmaceutical production and other fields, providing an effective technical means for the comprehensive utilization of tomato seeds.

[0003] Studies have shown that tomato seeds are rich in nutrients such as protein, oils, vitamins, and minerals, possessing high nutritional and medicinal value. Tomato seed oil contains a high proportion of linoleic acid and linolenic acid, which have certain health benefits, including lowering blood pressure, blood lipids, and blood sugar. Lycopene and lycopene, among other active ingredients, can also be extracted from tomato seeds, exhibiting antioxidant, anti-aging, and anti-cancer bioactivities. Therefore, tomato seeds have broad market prospects and economic value.

[0004] Currently, in households, tomatoes are mainly placed in a sink and the seeds are removed manually by peeling and washing them. This manual peeling method is inefficient and labor-intensive. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] In view of the problems existing in the above and / or existing tomato seed peeling processes, the present invention is proposed.

[0007] Therefore, the purpose of this invention is to provide a tomato seed extraction device that can remove tomato seeds from tomatoes, thereby improving extraction efficiency and reducing manual labor intensity.

[0008] To address the aforementioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0009] A tomato seed extraction device, comprising:

[0010] The cylinder body includes an outer cylinder body and an inner cylinder body;

[0011] An opening and closing cutting mechanism is provided at the bottom of the cylinder, and the placement port is connected to the inner cylinder and has the same inner diameter. It includes an outer shell and an opening and closing cutting assembly. The opening and closing cutting assembly has a movable cutting screen plate and has a first state in which the placement port is closed by the movable cutting screen plate and a second state in which the placement port is opened by the movable cutting screen plate.

[0012] When the cylinder rotates in the first direction, the cylinder drives the opening and closing cutting assembly to form a first state; when the cylinder rotates in the second direction opposite to the first direction, the cylinder drives the opening and closing cutting assembly to form a second state.

[0013] The compression component can move axially along the inner wall of the inner cylinder to compress the space of the inner cylinder.

[0014] In a preferred embodiment of the tomato seed extraction device of the present invention, the compression assembly includes a piston cylinder with a closed bottom and a threaded groove at the top, and a screw that is partially located in the threaded groove and whose outer wall engages with the threaded groove.

[0015] In a preferred embodiment of the tomato seed extraction device of the present invention, the outer wall of the piston cylinder is provided with a guide groove, and the inner wall of the inner cylinder is provided with a guide post that cooperates with the guide groove.

[0016] As a preferred embodiment of the tomato seed extraction device of the present invention, the top of the screw has a knob handle for easy rotation.

[0017] In a preferred embodiment of the tomato seed extraction device of the present invention, the outer wall of the outer cylinder has a toothed rack;

[0018] The opening and closing cutting assembly includes a fixed ring seat fixed in the outer shell, a first transmission component coaxially arranged with the fixed ring seat, and a plurality of second transmission components that are transmissionally connected to the first transmission component and fixedly connected to the movable cutting mesh plate.

[0019] The outer wall of the fixed ring seat has an extension seat extending from the inside of the outer shell to the outside, and the extension seat has a transmission assembly that drives the rack.

[0020] When the cylinder rotates, the rack drives the transmission assembly to rotate. The transmission assembly is driven by a first transmission component to rotate multiple second transmission components, which in turn drive multiple movable cutting mesh plates connected to the first transmission component to rotate inward to close the placement opening or rotate outward to open the placement opening.

[0021] As a preferred embodiment of the tomato seed extraction device of the present invention, the transmission component includes a first transmission gear located on the extension seat and meshing with the rack and an intermediate transmission gear meshing with the first transmission gear.

[0022] The first transmission component is a gear ring, which has incomplete external teeth and complete internal teeth, and the external teeth mesh with the intermediate transmission gear;

[0023] The second transmission component consists of multiple second transmission gears that mesh with the gear ring and are circumferentially distributed. The second transmission gears are fixedly connected to the movable cutting mesh plate.

[0024] In a preferred embodiment of the tomato seed extraction device of the present invention, the movable cutting mesh plate includes a fixed-axis rotating part, a frame connected to the fixed-axis rotating part, and a cutting mesh arranged in the frame.

[0025] As a preferred embodiment of the tomato seed extraction device of the present invention, the frame has an inwardly concave cutting surface and an outwardly convex enclosure surface.

[0026] The fixed-axis rotating part has a first curved surface connected to the cutting curved surface and a second curved surface connected to the first curved surface;

[0027] The curvatures of the cutting surface, the enclosure surface, the first surface, and the second surface are all the same. When the movable cutting mesh plate rotates inward to close the placement opening, the cutting surface and the first surface of the next movable cutting mesh plate are in contact with the enclosure surface of the previous movable cutting mesh plate. When the movable cutting mesh plate rotates outward to open the placement opening, the second surface of the next movable cutting mesh plate is in contact with the enclosure surface of the previous movable cutting mesh plate.

[0028] In a preferred embodiment of the tomato seed extraction device of the present invention, the cutting mesh is woven from metal wire and has tiny perforations.

[0029] In a preferred embodiment of the tomato seed extraction device of the present invention, the top of the outer cylinder has a support arranged in a ring, and the end of the support has a limiting ring.

[0030] The outer wall of the screw has a first annular barrier and a second annular barrier, and the limiting ring is located between the first annular barrier and the second annular barrier.

[0031] Compared with the prior art, the present invention has the following advantages: the tomato seed extraction device uses a rotating cylinder to drive an opening and closing cutting mechanism to cut the tomato seed coat into the inner cylinder. Then, the compression component squeezes the tomato into the inner cylinder, expelling the juice and pulp, leaving the tomato seeds. Finally, the opening and closing cutting mechanism is opened to remove the tomato seeds, which improves the peeling efficiency and reduces the intensity of manual labor. Attached Figure Description

[0042] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0043] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0044] This invention provides a tomato seed extraction device that can remove tomato seeds from tomatoes, improving extraction efficiency and reducing manual labor intensity.

[0045] Example 1:

[0046] Please see Figures 1-5 The tomato seed extraction device includes a cylinder 100, an opening and closing cutting mechanism 200, and a compression component 300.

[0047] The cylinder 100 includes an outer cylinder 110 and an inner cylinder 120. The inner cylinder 120 is used to store tomatoes that have been cut and have entered into it. The outer cylinder 110 is used to rotate and drive the opening and closing cutting mechanism 200 to cut the tomatoes.

[0048] The opening and closing cutting mechanism 200 is located at the bottom of the cylinder 100, and the placement port 200a is connected to the inner cylinder 120 and has the same inner diameter. The placement port 200a is used to place the tomatoes that need to be cut. Specifically, the opening and closing cutting mechanism 200 includes an outer shell 210 and an opening and closing cutting assembly 220. The opening and closing cutting assembly 220 has a movable cutting screen 220a, and the opening and closing cutting assembly 220 has a first state in which the placement port 200a is closed by the movable cutting screen 220a and a second state in which the placement port 200a is opened by the movable cutting screen 220a.

[0049] The compression assembly 300 can move axially along the inner wall of the inner cylinder 120, compressing the space of the inner cylinder 120, thereby expelling the air inside the inner cylinder 120 and squeezing the plant tissue, so that the juice and pulp are discharged from the seed extractor. Specifically, in this embodiment, the compression assembly 300 includes a piston cylinder 310 with a closed bottom and a threaded groove at the top, and a screw 320 partially located in the threaded groove and whose outer wall meshes with the threaded groove. When the screw 320 rotates, it can drive the piston cylinder 310 to move axially along its inner wall inside the inner cylinder 120.

[0050] Furthermore, in this embodiment, in order to ensure the stable operation of the compression assembly 300, the outer wall of the piston cylinder 310 is provided with a guide groove 310a, the inner wall of the inner cylinder 120 is provided with a guide post 120a that cooperates with the guide groove 310a, the top of the outer cylinder 110 has a bracket 110b distributed in a ring, the end of the bracket 110b has a limiting ring 110c, the outer wall of the screw 320 has a first annular barrier 320b and a second annular barrier 320c, and the limiting ring 110c is located between the first annular barrier 320b and the second annular barrier 320c, so that the screw 320 remains stable during rotation, and the top of the screw 320 has a knob handle 320a for easy turning.

[0051] Combination Figures 1-5 The specific operation process of the tomato seed extraction device of this embodiment is as follows:

[0052] When deseeding tomatoes, insert half of the tomato into the placement opening 200a of the opening and closing cutting mechanism 200, and then rotate the outer cylinder 110 counterclockwise. At this time, the movable cutting screen 220a of the opening and closing cutting assembly 220, driven by the outer cylinder 110, cuts the entire central part of the tomato into the inner cylinder 120. Then, stop rotating the outer cylinder 110 and rotate the screw 320. During the rotation of the screw 320, the piston cylinder 310 is driven downward to expel the air in the inner cylinder 120 and squeeze the plant tissue, so that the juice and pulp are discharged from the seed extractor. Then, rotate the outer cylinder 110 clockwise. When the outer cylinder 110 rotates clockwise, it drives the movable cutting screen 220a to rotate outward, opening the placement opening 200a, at which point the tomato seeds can be removed.

[0053] Example 2:

[0054] Figures 1-6 The diagram shown is a structural schematic of a second embodiment of a tomato seed extraction device according to the present invention. Please refer to [link / reference]. Figure 6 Unlike the above embodiments, the tomato seed extraction device of this embodiment has a rack 110a on the outer wall of the outer cylinder 110. The opening and closing cutting assembly 220 includes a fixed ring seat 220b fixed inside the outer shell 210, a first transmission component coaxially arranged with the fixed ring seat 220b, and a plurality of second transmission components that are connected to the first transmission component and fixedly connected to the movable cutting mesh plate 220a. The outer wall of the fixed ring seat 220b has an extension seat 220b-1 extending from the inside of the outer shell 210 to the outside. The extension seat 220b-1 has a transmission component that drives the rack 110a.

[0055] When the cylinder 100 rotates, the rack 110a drives the transmission assembly to rotate. The transmission assembly is driven by the first transmission component to rotate multiple second transmission components, which in turn drive multiple movable cutting mesh plates 220a connected to the first transmission component to rotate inward to close the placement port 200a or rotate outward to open the placement port 200a.

[0056] Example 3:

[0057] Figures 1-6 A schematic diagram of a third embodiment of the tomato seed extraction device of the present invention is also shown; please refer to [link / reference]. Figures 1-6This embodiment of a tomato seed extraction device includes a transmission assembly comprising a first transmission gear 220b-2 located on an extension seat 220b-1 and meshing with a rack 110a, and an intermediate transmission gear 220b-3 meshing with the first transmission gear 220b-2. The first transmission component is a gear ring 220d, which has incomplete external teeth 220d-1 and complete internal teeth 220d-2. The external teeth 220d-1 mesh with the intermediate transmission gear 220b-3. The second transmission component consists of multiple second transmission gears that mesh with the gear ring 220d and are circumferentially distributed. The transmission gear 220c is fixedly connected to the movable cutting screen plate 220a. When the cylinder 100 rotates, the rack 110a drives the first transmission gear 220b-2 to rotate. The first transmission gear 220b-2 drives the gear ring 220d to rotate through the intermediate transmission gear 220b-3. During the rotation of the gear ring 220d, the second transmission gear 220c rotates synchronously with the gear ring 220d, causing the corresponding movable cutting screen plate 220a to rotate inward to close the placement port 200a or rotate outward to open the placement port 200a.

[0058] Moreover, in this embodiment, since the second transmission gear 220c is circumferentially distributed and meshes with the internal teeth 220d-2 of the gear ring 220d, the position of the gear ring 220d is fixed by the internal teeth 220d-2, and there is no need to add an additional position fixing structure to the gear ring 220d.

[0059] Example 4:

[0060] Figures 1-8 A schematic diagram of a third embodiment of the tomato seed extraction device of the present invention is also shown; please refer to [link / reference].

The frame 220a-2 has an inwardly recessed cutting surface 220a-2a and an outwardly protruding enclosure surface 220a-2b. The fixed-axis rotating part 220a-1 has a first curved surface 220a-1a connected to the cutting surface 220a-2a and a second curved surface 220a-1b connected to the first curved surface 220a-1a.

[0061] The cutting surface 220a-2a, the enclosure surface 220a-2b, the first surface 220a-1a, and the second surface 220a-1b all have the same curvature to ensure that the movable cutting mesh plate 220a can be completely closed when closed. When the movable cutting mesh plate 220a rotates inward to close the placement opening 200a, the cutting surface 220a-2a and the first surface 220a-1a of the next movable cutting mesh plate 220a are in contact with the enclosure surface 220a-2b of the previous movable cutting mesh plate 220a. When the movable cutting mesh plate 220a rotates outward to open the placement opening 200a, the second surface 220a-1b of the next movable cutting mesh plate 220a is in contact with the enclosure surface 220a-2b of the previous movable cutting mesh plate 220a. Preferably, in this embodiment, the cutting mesh 220a-3 is woven from metal wire and has tiny perforations.

[0062] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner.
