Description

Technical Field

[0001] This utility model relates to the technical field of lemon juicing equipment, specifically to a manual lemon juicing device. Background Technology

[0002] Lemons, a nutrient-rich fruit, are abundant in vitamin C, flavonoids, citric acid, and other beneficial components, offering antioxidant, immune-boosting, and digestive-aiding effects. Juicing is an ideal way to better utilize the nutritional value and unique flavor of lemons. Lemon juice can be easily added to various beverages, such as lemonade, lemon tea, and cocktails, adding a refreshing acidity and fruity aroma. With increasing health awareness, the demand for fresh, natural lemon juice is growing, driving the continuous development of lemon juicing technology to obtain lemon juice more efficiently, conveniently, and with higher quality.

[0003] A multifunctional ceramic juicing device disclosed in authorization announcement number (CN207949600U) includes a ceramic top cover of the same diameter, a ceramic juicing plate, and a ceramic collection bowl. The interior of the ceramic top cover is hollow and conical, fitting into the upper part of the ceramic juicing plate. A juicing column is located in the middle of the ceramic juicing plate. During operation, one end of a fruit such as a lemon is cut off, the cut is aligned with the tip of the juicing column, and the juicing is pressed down vertically and rotated. The sharp tip of the juicing column quickly penetrates the fruit, while the wide column continuously squeezes the pulp during rotation. Simultaneously, the juice squeezed out flows along the grooves to the bottom wall of the juicer, eventually flowing into the ceramic collection bowl below, easily achieving manual juicing.

[0004] The structure disclosed in this patent has flaws in practical application, specifically as follows: When a user places a lemon with one end cut off, aligns the cut with the tip of the juicing column, and applies vertical pressure while rotating, the pulp is subjected to high-intensity compression against the top-narrow, bottom-wide juicing column. During this process, due to the lack of obstructions and guide components, the squeezed juice cannot flow into the collection bowl along the preset path but instead forms a high-speed spray. The splashed juice not only contaminates the work surface, increasing the cleaning burden, but may also splash onto the user's clothes or face, seriously affecting the comfort and convenience of the user experience and greatly reducing user satisfaction. Utility Model Content

[0005] The purpose of this utility model is to provide a manual lemon juicer that addresses the problem in the existing technology where the juicer process lacks an effective anti-splash structure, causing juice to splash everywhere, contaminating the work surface and reducing the user experience. This utility model proposes a solution to reduce the splashing of juice during the juicing process, reduce the degree of contamination of the work surface, and improve the overall user experience.

[0006] This utility model is achieved through the following technical solution:

[0007] A manual lemon juicing device includes: a juicing container with a juicing chamber inside; a pressing cap rotatably connected to the juicing container; a pressing column with a conical structure, rotatably mounted inside the pressing cap, and extending into the juicing chamber; and multiple pressing blades arranged along the circumference of the pressing column, with a juice discharge guide groove formed between adjacent pressing blades; wherein, in the closed state, the pressing cap rotates to be parallel to the juicing container, thereby sealing the juicing chamber; and in the open state, the pressing cap rotates to be perpendicular to the juicing container, thereby opening the juicing chamber.

[0008] Furthermore, in this invention, the bottom of the juicing chamber is provided with a plurality of positioning pins, the free end of which is a spike structure. The positioning pins form a positioning fit with the surface of the lemon to limit the displacement of the lemon during the juicing process.

[0009] Furthermore, in this utility model, the bottom end of the juicing container is provided with a connecting hole; the positioning pin passes through the connecting hole, and the positioning pin is a telescopic structure, which can extend into the juicing container for a preset length.

[0010] Furthermore, in this utility model, the aforementioned positioning pin includes: a fixed sleeve, which has a hollow structure and is installed at the bottom of the juicing container; a movable insert rod, one end of which passes through a connecting hole and the other end of which is fitted inside the fixed sleeve, with the movable insert rod and the fixed sleeve slidingly engaged; a return spring, one end of which is connected to the inner wall of the fixed sleeve and the other end of which is connected to the movable insert rod; a pushing member, which is at least partially fitted inside the fixed sleeve and is threadedly engaged with the fixed sleeve; and a transmission push rod, one end of which is connected to the pushing member and the other end of which can abut against the movable insert rod.

[0011] Furthermore, in this utility model, the aforementioned pressing cap is provided with an assembly interface, and the inner wall of the assembly interface is provided with an annular groove along the circumferential direction; the outer wall of the pressing column is provided with an annular boss along the circumferential direction, and the annular boss is located in the annular groove.

[0012] Furthermore, in this invention, a grip handle is installed on the outer wall of the juicing container; an operating handle is installed on the outer wall of the pressing cap, and the operating handle can be rotated to fit against the grip handle.

[0013] Furthermore, in this invention, the bottom of the juicing container is provided with multiple filtrate passages.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0015] 1. This utility model achieves directional flow and splash suppression of lemon juice through the coordinated design of the pressing cap's shielding structure and the juice drainage guide channel. When the pressing column rotates inside the lemon, the sealed space formed by the pressing cap and the closed juicing container constitutes a ring-shaped shield, preventing juice from splashing outwards. Simultaneously, the juice drainage guide channel formed between the circumferentially distributed pressing blades guides the squeezed juice along a preset path to the bottom of the juicing container, preventing high-speed splashing that could contaminate the work surface or splash onto the user. This structural design, through the dual effects of physical shielding and flow guidance, significantly improves the cleanliness of the juicing process and the user's operating experience.

[0016] 2. This utility model achieves adaptive positioning for lemons of different sizes through the threaded engagement structure between the pusher and the fixed sleeve. When adapting to large lemons, the operator rotates the pusher clockwise, causing the pusher to drive the transmission push rod forward, increasing the extension length of the movable insert along the fixed sleeve, thus allowing the movable insert to penetrate deep into the bottom of the lemon for positioning. When processing small lemons, the pusher is rotated in the opposite direction, causing the pusher to move the transmission push rod backward, shortening the extension length of the movable insert, and avoiding interference between the movable insert and the stroke of the pressing column during juicing.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0025] Example

[0026] Please refer to Figure 1 This utility model provides a manual lemon juicing device. It includes a juicing container 1, with a juicing chamber 7 inside for holding lemons; and a pressing cap 2, which is rotatably connected to the juicing container 1 by a pin, allowing them to rotate relative to each other. A conical pressing column 3 is rotatably mounted inside the pressing cap 2, extending into the juicing chamber 7. Multiple pressing blades 4 are distributed circumferentially on the pressing column 3, with drainage channels 5 formed between adjacent pressing blades 4. When the juicing chamber 7 is in the closed state, the pressing cap 2 is rotated to be parallel to the juicing container 1, sealing the juicing chamber 7. At this time, the pressing column 3 falls exactly into the chamber, and juicing can be carried out. When the juicing chamber 7 is in the open state, the pressing cap 2 is rotated to be perpendicular to the juicing container 1, opening the juicing chamber 7, making it easy for the operator to take out the juice and residue.

[0027] In the operation process, the operator first cuts the top surface of the lemon to create a flat positioning reference surface. Then, the pre-treated lemon is placed inside the juicing chamber 7, and the pressing cap 2 is rotated to seal the juicing chamber 7. During this process, the pressing column 3 moves synchronously with the pressing cap 2, cutting into the lemon's internal tissue from the top, achieving initial disruption of the lemon's cell structure. Then, manual force is applied to drive the pressing column 3 to rotate around its own axis, causing multiple circumferentially arranged pressing blades 4 to rotate synchronously. During rotation, each pressing blade 4 continuously rolls, squeezes, and spirals against the inner wall of the lemon. During this pressing process, the pressing cap 2 effectively confines the splashed juice, while the extracted juice flows along the path of the drain guide 5 to the collection area at the bottom of the juicing chamber 7.

[0028] Please refer to Figure 2 and Figure 3 In some embodiments of this application, the bottom of the juicing chamber 7 is provided with several positioning pins 9, the free ends of which are spiked. The positioning pins 9 form a positioning fit with the surface of the lemon, and the positioning pins 9 penetrate the bottom tissue of the lemon, effectively limiting the displacement of the lemon during the juicing process. After the lemon is placed into the juicing chamber 7, the operator presses it towards the bottom of the juicing chamber 7, causing the spiked structure to embed into the bottom of the lemon, forming a mechanical lock.

[0029] The positioning pin 9 establishes a stable positioning reference, ensuring that the lemon maintains a fixed posture when the pressing column 3 rotates, thereby allowing relative movement between the pressing blades 4 and the inner wall of the lemon. This positioning mechanism enables the circumferentially distributed pressing blades 4 to act on the inner wall of the lemon, achieving efficient juicing through a combination of rolling compression and spiral scraping. The spiked structure design of the positioning pin 9 ensures reliable positioning while avoiding excessive damage to the lemon pulp, achieving a balance between positioning and juicing efficiency.

[0030] Please refer to Figure 3 The juicing container 1 has a connecting hole 13 at its bottom, and a positioning pin 9 passes through the connecting hole 13. The positioning pin 9 is telescopic, allowing the operator to adjust its length according to the size of the lemon. The positioning pin 9 extends into the juicing chamber 7 to a preset length. When processing large lemons, the extension length of the positioning pin 9 is increased, and the spiked structure of the positioning pin 9 inserts into the bottom of the lemon to an appropriate depth, preventing displacement during juicing. When processing small lemons, the extension length of the positioning pin 9 is shortened, ensuring that the positioning pin 9 is embedded in the bottom of the lemon for effective positioning, while preventing the positioning pin 9 from inserting too deeply into the pulp, thus avoiding interference with the downward path of the pressing column 3. This ensures that the pressing column 3 can completely reach the bottom of the lemon, achieving full-area juicing operation. This telescopic positioning pin 9, through adaptive length adjustment, can establish a stable positioning reference in juicing scenarios with lemons of different sizes, while ensuring that the working stroke of the pressing column 3 is not obstructed, thus meeting the dual requirements of positioning reliability and juicing integrity.

[0031] Please refer to Figure 3 Specifically, the fixed sleeve 14 is a hollow tubular component, installed at the bottom of the juicing container 1 and coaxially connected to the connecting channel 13; one end of the movable insert rod 15 extends through the connecting channel 13 into the juicing cavity 7, and the other end is nested inside the fixed sleeve 14. Guide sliders 19 are symmetrically arranged on the outer side of the movable insert rod 15, and guide grooves 20 are symmetrically arranged on the inner wall of the fixed sleeve 14 to form a locking sliding pair, ensuring that the movable insert rod 15 moves relative to the fixed sleeve 14.

[0032] The pusher 18 is a cylindrical component with external threads, which is at least partially fitted inside the fixed sleeve 14 and forms a transmission engagement with the internal threads of the fixed sleeve 14. One end of the transmission push rod 17 is fixedly connected to the pusher 18, and the other end can abut against the end face of the movable insert rod 15. When the operator rotates the pusher 18 clockwise, the pusher 18 moves axially along the fixed sleeve 14 and drives the transmission push rod 17 forward, causing the movable insert rod 15 to extend into the juicing chamber 7, which is suitable for deep positioning of large lemons. When processing small lemons, the pusher 18 is rotated in the opposite direction to move the transmission push rod 17 backward, and the transmission push rod 17 disengages from the movable insert rod 15. When the movable insert rod 15 is inserted into the lemon, the movable insert rod 15 is further retracted to the appropriate length by the reaction force of the bottom of the lemon, which ensures that the pressing column 3 is embedded and positioned, and avoids excessive insertion that affects the downward path of the pressing column 3.

[0033] One end of the return spring 16 is connected to the inner wall of the fixed sleeve 14, and the other end is connected to the movable insertion rod 15, forming an elastic positioning adjustment mechanism. When the operator has difficulty judging the extension length of the movable insertion rod 15 due to differences in experience, the movable insertion rod 15 can be preset to a larger extension length to ensure that the movable insertion rod 15 reliably pierces the lemon surface to achieve initial positioning. After the lemon is positioned, the adjusting push member 18 shortens the extension length of the movable insertion rod 15. At this time, since a puncture hole has been formed on the lemon surface, the movable insertion rod 15 can still maintain its current extension amount under the elastic force of the return spring 16, without the need for continuous support from the transmission push rod 17.

[0034] When the pressing column 3 is inserted into the lemon, if the initial extension length of the movable insert 15 exceeds the actual requirement, the pressure applied by the pressing column 3 will be transmitted to the movable insert 15, causing it to retract against the elastic force of the return spring 16. During this process, the pressing column 3 will not completely push the movable insert 15 out of the lemon tissue, ensuring that the movable insert 15 remains within the puncture hole. In this partially retracted state, the movable insert 15 provides a continuous limiting effect through its mechanical engagement with the wall of the puncture hole. The movable insert 15 avoids rigid interference with the pressing column 3 through the elastic deformation of the return spring 16, and maintains material stability by continuously positioning the lemon with the movable insert 15, ensuring that the working stroke of the juicing component is not obstructed.

[0035] Please refer to Figure 4 In some embodiments of this application, the inner wall of the assembly interface 10 of the pressing cap 2 is provided with an annular groove 21 along the circumference. Correspondingly, the outer wall of the pressing column 3 is provided with an annular boss 6, which is embedded in the annular groove 21 to form a rotating pair connection structure. This design allows the pressing column 3 to rotate around its own axis within the assembly interface 10. At the same time, the cooperation between the annular boss 6 and the annular groove 21 effectively restricts the axial displacement of the pressing column 3, ensuring that it maintains a stable working posture during the juicing process.

[0036] It should be noted that the juicing container 1 and the pressing cap 2 are connected via a rotating joint, and the pressing rotor 3 is installed inside the pressing cap 2. When juicing lemons, the lemon is first placed in the juicing chamber 7 of the juicing container 1. Then, by rotating the juicing container 1 and the pressing cap 2 relative to each other, the pressing cap 2 seals the juicing chamber 7, while the pressing rotor 3 is inserted into the lemon. However, during the process of rotating the pressing cap 2 and causing the pressing rotor 3 to rotate, the lemon may interfere with the rotation path of the pressing rotor 3.

[0037] To solve this problem, a lifting and lowering mechanism can be designed between the pressing column 3 and the pressing cap 2: before the pressing cap 2 rotates towards the juicing container 1, the pressing column 3 is raised relative to the pressing cap 2 to avoid the lemon surface; when the pressing cap 2 has fully rotated to close with the juicing container 1, the pressing column 3 moves downward to insert into the lemon. This lifting and lowering linkage design between the pressing column 3 and the pressing cap 2 effectively avoids interference from the lemon with the pressing column 3 during rotation, ensuring smooth operation of the device.

[0038] Specifically, the outer side wall of the pressing column 3 has axially oriented lifting guide grooves on opposite sides, and the inner side wall of the annular boss 6 has corresponding lifting sliders. The two lifting sliders are respectively embedded in the two lifting guide grooves to form a sliding fit structure. This design allows the pressing column 3 to move up and down along the axial direction of the annular boss 6. At the same time, through the circumferential constraint of the lifting sliders and the lifting guide grooves, it is ensured that the pressing column 3 can drive the annular boss 6 to rotate synchronously when it rotates, realizing the coordinated action of lifting and rotation.

[0039] Please refer to Figure 1 In some embodiments of this application, a grip handle 11 is installed on the outer wall of the juicing container 1, and an operating handle 12 is installed on the outer wall of the pressing cap 2. The grip handle 11 and the operating handle 12 form a force transmission structure through the lever principle. The operating handle 12 can rotate to fit against the grip handle 11. The grip handle 11 and the operating handle 12 form a collinear lever structure, which can enhance the stability of force application during juicing by holding it with both hands, and reduce space occupation when storing it, thus achieving a unity of functionality and portability.

[0040] Please refer to Figure 1 In some embodiments of this application, the bottom of the juicing container 1 is provided with several filtration holes 8. During the juicing process, the squeezed juice can flow into the juice receiving container below through the filtration holes 8, achieving directional collection of juice and separation of residue. At the same time, the pore size design of the filtration holes 8 can intercept lemon seeds inside the juicing container 1, preventing them from falling into the juice receiving container with the juice, thus ensuring the purity of the finished juicing product.

[0041] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
