Description

Technical Field

[0001] This utility model relates to the technical field of coconut processing equipment, specifically to a coconut juice extraction device. Background Technology

[0002] Coconut juice is the juice extracted from the coconut fruit of the coconut palm, a plant in the palm family. It contains protein, fat, vitamin C, and minerals such as calcium, phosphorus, iron, potassium, magnesium, and sodium, making it an extremely nutritious beverage that is widely loved by consumers.

[0003] Traditional coconut juice extraction equipment requires clamping and securing the coconut before opening it, or a series of tedious manual operations after opening: manually picking up the coconut, turning it over, pouring out the coconut juice, filtering out the coconut shell residue produced during the opening process, and finally collecting the coconut juice into a container. These procedures are not only time-consuming and labor-intensive, but also prone to causing coconut juice to splash and spill.

[0004] In addition, traditional juice extraction equipment often causes extensive damage to the coconut shell during the coconut opening process. This not only leads to a large amount of coconut shell residue mixing into the coconut juice and causing pollution, but also makes it impossible for the coconut shell to maintain its intact shape and lose its value as a container for reuse. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a coconut juice extraction device that solves the technical problems of complex operation and low purity of coconut juice obtained by existing juice extraction equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a coconut juice extraction device, including a base, a shell assembly, and a juice extraction component. The shell assembly is disposed on the base, and the shell assembly and the base surround an installation cavity. The juice extraction component is installed in the installation cavity.

[0007] The housing assembly includes a housing body and a protective cover. The housing body is disposed on the base, and a first protrusion and a second protrusion extend from the portion of the housing body away from the base. The first protrusion has a positioning hole on the side facing the base, and the second protrusion has a liquid outlet hole on the side facing the base. The protective cover is fitted over the outside of the first protrusion, and the protective cover reciprocates in the direction toward the base.

[0008] The juice extraction assembly includes a juice extraction needle, a liquid outlet connector, a transfer pump, and a drive platform. The juice extraction needle, the transfer pump, and the liquid outlet connector are connected by an infusion tube. The juice extraction needle is mounted on the drive platform. The drive platform drives the juice extraction needle to reciprocate through the positioning hole in the direction toward the base. The liquid outlet connector is exposed at least partially through the liquid outlet hole.

[0009] In one possible implementation, the juice extraction needle includes a connecting portion, and a needle shaft and a tapered needle tip respectively connected to both ends of the connecting portion. The end of the needle shaft away from the connecting portion is connected to the infusion tube. The needle shaft has a hollow structure, and a juice extraction hole is formed in the region of the needle shaft near the connecting portion. The outer diameter of the needle shaft is smaller than the maximum outer diameter of the tapered needle tip.

[0010] In one possible implementation, grooves are provided on opposite sides of the first protrusion, which are arranged in the direction toward the base, and both sides of the protective cover are installed in the grooves.

[0011] In one possible implementation, the drive platform includes a drive component and a support, the drive component being mounted on the base, the support being mounted on the drive component, and the juice extraction needle being mounted on the support.

[0012] In one possible implementation, the driving element is an electric actuator.

[0013] In one possible implementation, the coconut juice extraction device further includes a drive motor, which is electrically connected to both the electric push rod device and the transfer pump.

[0014] In one possible implementation, the base is provided with a placement area and an installation area, both the housing assembly and the juice extraction assembly are installed in the installation area, and the placement area is used to place the coconut to be juiced and the container.

[0015] The beneficial effects of this utility model are that, compared with the prior art, this utility model forms an installation cavity by cooperating the shell component and the base, integrating the juice extraction component and the drive platform, and combining the reciprocating motion of the protective cover to achieve automatic juice extraction without clamping the coconut, while reducing coconut shell residue pollution and directly completing the coconut juice filling, thereby simplifying the juice extraction operation, improving the purity of the coconut juice, and thus solving the technical problems of complex operation and low purity of coconut juice obtained by existing juice extraction equipment.

[0022] To solve the above-mentioned technical problems, this utility model provides a coconut juice extraction device. The technical solution and embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0024] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection" and "joining" should be interpreted broadly, for example, they can refer to fixed connection, detachable connection, or integral connection; for those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0025] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0026] In traditional coconut juice extraction equipment, mechanical interference between the coconut fixing and turning mechanisms increases structural redundancy, and the rigid contact of the clamping device easily causes localized stress concentration in the coconut shell. The interruption introduced by manual operation exposes the coconut juice collection path to an open environment, increasing the contact area between the liquid medium and air, accelerating oxidation. Simultaneously, the uncontrollable trajectory of coconut shell fragments in free fall under gravity leads to decreased solid-liquid separation efficiency. Repeated mechanical contact during the equipment's operation lowers the threshold for damage to coconut shell integrity, and irreversible geometric deformation significantly reduces the secondary utilization rate of the coconut shell.

[0027] Faced with the aforementioned problems, this application first considers how to eliminate the mechanical interference between the coconut fixing mechanism and the flipping mechanism in traditional equipment. Existing clamping devices not only increase structural complexity, but their rigid contact can also cause the propagation of microcracks in the coconut shell. To address this, this application attempts to avoid physical constraints through spatial reconstruction and instead utilize the coconut's own gravity for positioning. Further analysis of the torque difference problem during the puncture process reveals that the axial displacement deviation originates from a multi-point stress state, necessitating the establishment of a single-point force application mechanism. Regarding the issue of coconut shell fragment deposition with the fluid, this application explores setting a physical isolation layer in the juice extraction path while maintaining the unobstructed flow of the fluid channel. Finally, to solve the problem of secondary utilization of coconut shells, the focus is on how to control the puncture hole size to maximize the preservation of the coconut shell's structural integrity while ensuring juice extraction efficiency.

[0028] like Figures 1 to 3 As shown, this utility model provides a coconut juice extraction device 1, including a base 11, a shell assembly 12 and a juice extraction assembly 13. The shell assembly 12 is disposed on the base 11, and the shell assembly 12 and the base 11 surround an installation cavity (not shown in the figure). The juice extraction assembly 13 is installed in the installation cavity.

[0029] The housing assembly 12 includes a housing body 121 and a protective cover 122. The housing body 121 is mounted on the base 11, and a first protrusion 123 and a second protrusion 124 extend from the portion of the housing body 121 away from the base 11. The first protrusion 123 has a positioning hole 1231 on the side facing the base 11, and the second protrusion 124 has a liquid outlet hole 1241 on the side facing the base 11. The protective cover 122 is fitted over the first protrusion 123, and the protective cover 122 reciprocates in the direction toward the base 11.

[0030] The juice extraction assembly 13 includes a juice extraction needle 131, a liquid outlet connector 132, a transfer pump 133, and a drive platform 134. The juice extraction needle 131, the transfer pump 133, and the liquid outlet connector 132 are connected by an infusion tube 135. The juice extraction needle 131 is mounted on the drive platform 134. The drive platform 134 drives the juice extraction needle 131 to reciprocate through the positioning hole 1231 in the direction toward the base 11. The liquid outlet connector 132 is exposed at least partially through the liquid outlet hole 1241.

[0031] The base 11 refers to the base structure used to support the entire device. It can be made of metal or plastic and has sufficient weight and stability to prevent the device from tipping over.

[0032] The housing assembly 12 refers to the outer shell structure installed on the base 11. Specifically, it can be designed as a split type to facilitate assembly and maintenance. The shell body 121 and the base 11 together form an installation cavity to accommodate other components.

[0033] The mounting cavity refers to the enclosed space formed by the shell body 121 and the base 11. Specifically, it can adopt a sealed design to prevent liquid or debris from leaking out, while providing protection for the internal components.

[0034] The protective cover 122 refers to a movable cover fitted outside the first protrusion 123. Specifically, it can be a sliding structure or a guide rail to achieve reciprocating motion, used to cover the needle and prevent coconut shell fragments from splashing during the juice extraction process.

[0035] The juice extraction needle 131 is a sharp part used to pierce the coconut and extract juice. Specifically, it can be made of hollow stainless steel tube, and the end of the needle is connected to the infusion tube 135 to realize the juice transfer.

[0036] The drive platform 134 refers to the mechanical structure that controls the movement of the juice extraction needle 131. Specifically, it can be driven by an electric push rod or a hydraulic device to move the support 1342 up and down, thereby driving the needle to accurately pierce the coconut.

[0037] The liquid outlet connector 132 refers to the interface component that connects to the infusion tube 135 and passes through the liquid outlet hole 1241. Specifically, it can adopt a quick-release design for easy cleaning and maintenance, and the exposed part can directly connect to the container to realize the coconut juice filling.

[0038] During operation, the coconut is placed on the base 11. The drive platform 134 moves the extraction needle 131 downwards, passing through the positioning hole 1231 and piercing the coconut. The extraction needle 131 extracts coconut juice, which is then transported to the transfer pump 133 via the infusion tube 135. The transfer pump 133 pumps the coconut juice to the outlet connector 132, from which it flows out through the outlet hole 1241. The protective cover 122 reciprocates during the extraction process to prevent coconut juice from splashing. The entire process is completed automatically without manual operation.

[0039] The design of the positioning hole 1231 and the liquid outlet hole 1241 enables precise positioning of the juice extraction needle 131 and orderly output of coconut juice. The reciprocating motion of the drive platform 134 ensures that the juice extraction needle 131 can accurately pierce the coconut and extract the coconut juice. The protective cover 122 prevents coconut juice from splashing, ensuring a clean and hygienic extraction process. The overall structure is compact, and the components work together to achieve automated juice extraction.

[0040] It should be noted that in actual use, the coconut juice extraction device 1 can perform only the drilling operation without extracting juice, according to the customer's needs. This allows the operator to complete the coconut opening operation using the coconut juice extraction device 1. Specifically, this can be achieved by not turning on the transmission pump 133 and controlling the depth of the juice extraction needle 131 during the operation of the coconut juice extraction device 1.

[0041] In a preferred embodiment, the base 11 of the coconut juice extraction device 1 is made of stainless steel, which has good stability and corrosion resistance. The shell assembly 12 is injection molded from engineering plastic, making it lightweight and easy to install and disassemble. The shell body 121 is fixed to the base 11 with bolts, and the first protrusion 123 and the second protrusion 124 are integrally molded structures. The positioning hole 1231 and the liquid outlet hole 1241 are both designed with arc shapes and smooth inner walls to reduce friction.

[0042] The protective cover 122 is made of transparent acrylic material, allowing for easy observation of the juice extraction process. A spring is provided between the protective cover 122 and the first protrusion 123 to achieve reciprocating motion. The juice extraction needle 131 is made of food-grade stainless steel, such as 304 or 316 stainless steel, with a polished surface to reduce frictional resistance. The liquid outlet connector 132 is made of food-grade silicone material, which is soft and durable.

[0043] The drive platform 134 is driven by a stepper motor for precise control. The transfer pump 133 is a peristaltic pump to avoid direct contact with the coconut juice. The infusion tubing 135 is made of food-grade silicone tubing, which has good flexibility and sealing properties.

[0044] See Figure 4 Furthermore, the juice extraction needle 131 includes a connecting portion 1312, and a needle bar 1311 and a conical needle 1313 respectively connected to both ends of the connecting portion 1312. The end of the needle bar 1311 away from the connecting portion 1312 is connected to the infusion tube 135. The needle bar 1311 has a hollow structure, and a juice extraction hole 1314 is opened in the area of ​​the needle bar 1311 near the connecting portion 1312. The outer diameter of the needle bar 1311 is smaller than the maximum outer diameter of the conical needle 1313.

[0045] The connecting part 1312 serves as a transition structure between the needle bar 1311 and the conical needle 1313, forming a whole by fixing the needle bar 1311 and the conical needle 1313 at both ends respectively. The hollow structure of the needle bar 1311 forms a coconut juice flow channel, and its end away from the connecting part 1312 is sealed to the infusion tube 135 by threads or snaps.

[0046] Specifically, when the drive platform 134 drives the extraction needle 131 to pierce the coconut, the conical needle 1313 first penetrates the coconut shell to form an entrance, and the needle shaft 1311 then enters the interior of the coconut shell. Since the outer diameter of the needle shaft 1311 is smaller than the maximum outer diameter of the conical needle 1313, the opening size of the coconut shell matches the maximum outer diameter of the conical needle 1313, allowing external air to enter the interior of the coconut along the needle shaft 1311 to balance the pressure and reduce the resistance to the flow of coconut juice into the extraction hole 1314, so that the transfer pump 133 can smoothly extract coconut juice. When the extraction hole 1314 has completely entered the coconut meat layer, the transfer pump 133 extracts coconut juice through the hollow needle shaft 1311. The coconut juice enters the internal channel of the needle shaft 1311 through the extraction hole 1314 and is finally delivered to the container through the infusion tube 135. The tapered needle 1313's outer diameter difference design prevents coconut shell fragments from entering the juice extraction hole 1314. At the same time, the hollow structure of the needle shaft 1311 and the position of the juice extraction hole 1314 ensure that the coconut juice extraction path avoids the broken area of ​​the coconut shell, thereby reducing the risk of coconut shell residue mixing into the coconut juice.

[0047] like Figure 5 As shown, further, the first protrusion 123 has grooves 1232 on its opposite sides arranged in the direction toward the base 11, and both sides of the protective cover 122 are installed in the grooves 1232.

[0048] The slide groove 1232 is a strip-shaped groove extending along both sides of the first protrusion 123, and its length direction is consistent with the movement direction of the protective cover 122. The two side edges of the protective cover 122 may be provided with protrusions or slider structures to form a sliding fit with the slide groove 1232. The width of the slide groove 1232 is clearance-fitted with the protrusions or sliders on both sides of the protective cover 122, allowing the protective cover 122 to slide freely along the length direction of the slide groove 1232. The inner surface of the slide groove 1232 may be polished or coated with a lubricating coating to reduce the coefficient of friction.

[0049] Specifically, the protective cover 1232 needs to be manually lifted when placing the coconut to create enough space for it. After the coconut is placed, the protective cover 1232 falls naturally under gravity and comes into contact with the upper surface of the coconut. This not only prevents coconut juice from splashing during the juice extraction process and reduces the risk of stains, but also shields and isolates the juice extraction needle 131 to prevent operators from accidentally touching it, thus protecting the safety of the operators.

[0050] See Figure 3Furthermore, the drive platform 134 includes a drive component 1341 and a bracket 1342. The drive component 1341 is mounted on the base 11, the bracket 1342 is mounted on the drive component 1341, and the juice extraction needle 131 is mounted on the bracket 1342.

[0051] Specifically, the drive component 1341 is an electric push rod device.

[0052] The drive component 1341 is an electric actuator, which drives the bracket 1342 to move vertically through linear telescopic motion. The bracket 1342 is rigidly connected to the output end of the electric actuator, and the juice extraction needle 131 is fixed to the bracket 1342 by threads or a snap-fit ​​structure. The base 11 has mounting holes, and the electric actuator is fixed in the mounting holes by bolts. The bracket 1342 is made of aluminum alloy to reduce the overall weight.

[0053] Specifically, after being powered on, the electric actuator generates axial thrust, pushing the bracket 1342 to move vertically, thus driving the juice extraction needle 131 to complete the insertion of the positioning hole 1231. The bracket 1342 remains horizontal during movement to prevent the juice extraction needle 131 from shifting. The thrust parameters of the electric actuator must be set to ensure that it can penetrate the coconut shell without excessively damaging it. A buffer pad is provided at the connection between the bracket 1342 and the drive unit 1341 to reduce vibration during movement.

[0054] When the juice extraction needle 131 reaches the preset depth, the transfer pump 133 starts to extract coconut juice, and the support 1342 remains stationary to ensure the stability of the juice extraction process.

[0055] like Figure 3 As shown, the coconut juice extraction device 1 further includes a drive motor 136, which is electrically connected to the electric push rod device and the transfer pump 133 respectively.

[0056] The drive motor 136 synchronously controls the start and stop of the electric actuator and the transfer pump 133 via electrical signals. The drive motor 136 can be configured as an integrated dual-output shaft structure, with one output shaft connected to the lead screw of the electric actuator via a coupling, and the other output shaft connected to the rotor of the transfer pump 133 via a gear set. Alternatively, the drive motor 136 can be configured as a single-output shaft structure, transmitting power to the electric actuator and the transfer pump 133 via a transfer case. The drive motor 136 is connected to the electric actuator via a wire, and to the transfer pump 133 via another set of wires; both sets of wires are connected to the same control circuit board. The drive motor 136 can be further configured as a servo motor, with its speed adjusted by a frequency converter to adapt to the actuator stroke and pumping rate corresponding to different coconut sizes.

[0057] Specifically, when the drive motor 136 receives a start signal, it simultaneously outputs drive current to the electric push rod device and the transfer pump 133. The electric push rod device drives the juice extraction needle 131 to move downwards along the positioning hole 1231 and pierce the coconut. At the same time, the transfer pump 133 starts running, drawing coconut juice through the infusion tube 135 to the outlet connector 132. The current parameters of the drive motor 136 are set according to a preset program to match the insertion depth of the juice extraction needle 131 with the suction flow rate of the transfer pump 133. When the juice extraction needle 131 reaches the preset stroke position, the drive motor 136 stops outputting current, and the electric push rod device and the transfer pump 133 stop working synchronously. During this process, the synchronous control function of the drive motor 136 ensures the consistency of the timing between the needle insertion action and the coconut juice extraction action, avoiding coconut juice splashing or suction delay caused by manual step-by-step operation.

[0058] This application achieves centralized control of the electric push rod device and the transfer pump 133 by the drive motor 136, simplifying the control system structure and improving the coordination of the actions of each component. As a result, the coconut juice extraction process is smoother and more efficient, reducing possible jams or asynchrony during the extraction process, and improving overall extraction efficiency and user experience.

[0059] See Figure 3 Furthermore, the base 11 is provided with a placement area 111 and an installation area 112. The housing assembly 12 and the juice extraction assembly 13 are both installed in the installation area 112. The placement area 111 is used to place the coconut to be juiced and the container.

[0060] Through the above technical solution, this application achieves a functional zoning layout for the coconut juice extraction device 1, improving space utilization. The placement area 111 facilitates user placement and retrieval of coconuts and containers, simplifying operation. The installation area 112 centrally houses the core functional components, resulting in a compact structure. The zoning design makes the device appear neat and its functions clearly defined, enhancing the user experience.

[0061] In one alternative embodiment, the surface of the placement area 111 is machined to form an annular groove structure, the inner surface of the groove is covered with an elastic silicone layer, and the opening diameter of the annular groove is configured to form a clearance fit with the bottom diameter of a standard coconut. The mounting area 112 is spaced apart from the placement area 111 on the horizontal platform surface of the base 11. The edge of the mounting area 112 extends upward to form a semi-enclosed baffle structure, and a food-grade rubber sealing strip is attached to the inner side of the baffle. When the coconut is placed vertically in the annular groove, its bottom is embedded in the groove, achieving self-positioning through the deformation constraint of the silicone layer, and an annular gap space is formed between the baffle and the outer surface of the coconut.

[0062] Through the above technical solution, this application effectively solves the problem of juice extraction position deviation caused by unstable coconut positioning. By employing a composite positioning mechanism of geometric constraints and elastic materials, automatic centering and fixing of the coconut is achieved without the need for external clamping devices. The semi-enclosed baffle structure forms a physical isolation during coconut juice extraction, preventing coconut juice from splashing and contaminating the work area while maintaining operational visibility. This structural design balances positioning accuracy and operational convenience, ensuring that the entire juice extraction process meets food hygiene requirements.

[0063] In addition, in practical applications, eye-catching color markings can be set in the placement area 111 to indicate the placement positions of the coconuts to be juiced and the containers, reducing the risk of problems such as difficulty in extracting juice from the coconut juice extraction device 1 due to positional deviation, and also reducing the risk of coconut juice splashing due to container placement deviation, so as to reduce pollution and waste.

[0064] The above description is merely a preferred embodiment of the present utility model, and the specific embodiments described above are not intended to limit the present utility model. Various modifications and variations can be made within the scope of the technical concept of the present utility model. All refinements, modifications, or equivalent substitutions made by those skilled in the art based on the above description are within the scope of protection of the present utility model.
