[0036] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0037] See Figures 1-13 This utility model provides a micro fruit puree extrusion structure, which includes a container 1, a discharge pipe 2, an extrusion valve 4, and a drive ring 3;

[0038] The discharge pipe 2 is installed on the outer wall of the container 1, at the upper or lower end of the container, to facilitate the extrusion of material by the piston inside the container; the discharge pipe 2 has a circular cross-section, and a guide hole 20 is provided at the end of the discharge pipe 2, the axis of which is parallel to the axis of the discharge pipe 2, preferably coaxial; a discharge port 200 is provided at the end of the guide hole 20, which is connected to the container 1 for discharging material.

[0039] The extrusion valve 4 is fitted inside the guide hole 20 and can move axially but cannot rotate circumferentially. An extrusion port 402 is provided on the extrusion valve 4, which is connected to the guide hole 20. At the same time, a valve plug 411 is provided on the extrusion valve 4, which is used to block the outlet 200.

[0040] The drive ring 3 is annular and is sleeved on the outside of the discharge pipe 2 and the extrusion valve 4, and can rotate circumferentially. The first end of the drive ring 3 is rotatably connected to the extrusion valve 4, which can achieve relative rotation but not relative axial movement. The second end of the drive ring 3 is connected to the discharge pipe 2 by a spiral structure. Therefore, by rotating the drive ring 3, the extrusion valve 4 can be driven to move axially between the first position and the second position.

[0041] When in the first position, valve plug 411 blocks the discharge port 200, at which point extrusion cannot be achieved.

[0042] When in the second position, the valve plug 411 disengages from the discharge port 200, thereby connecting the extrusion port 402 to the discharge port 200, at which point extrusion can be achieved.

[0043] This application utilizes the circumferential rotation of the drive ring and the spiral structure to drive the axial movement of the extrusion valve, thereby achieving precise opening and closing of the valve plug at the discharge port. It can quickly switch between the discharge and stop discharge states, effectively avoiding fruit pulp dripping and waste, and improving ease of use.

[0044] The components are nested in a layout, with the drive ring sleeved outside the discharge pipe and the extrusion valve, and the extrusion valve built into the guide hole. The overall structure is compact, occupies little space, and is easy to integrate into various containers, adapting to different container sizes and usage scenarios.

[0045] The design of this extrusion valve, which can only move axially and cannot rotate circumferentially, ensures the relative position of the extrusion port and the guide hole is stable, the discharge direction and shape are controllable, and the extrusion process is smoother.

[0046] The extrusion structure of this micro-fruit puree machine is compact, small in size, easy and labor-saving to operate, and has low manufacturing cost.

[0047] The spiral groove structure has a self-locking property, which can prevent the extrusion valve from accidentally retracting under material pressure, ensuring operational stability and reliability.

[0048] The spiral structure in this application can take the following two forms;

[0049] Example 1: The spiral structure consists of an external thread on the outer wall of the discharge pipe 2 and an internal thread on the inner wall of the drive ring 3 that mates with the external thread. It has a simple structure and low manufacturing cost.

[0050] Example 2: The spiral structure includes a spiral groove 21 disposed on the outer wall of the discharge pipe 2 and a protrusion 31 disposed on the inner wall of the drive ring 3. The protrusion 31 cooperates with the spiral groove; through the rotation of the drive ring, axial movement is achieved under the action of the spiral groove 21 and the protrusion 31.

[0051] Compared to traditional threads, the combination of spiral grooves and protrusions reduces the contact area of ​​the threaded surface, lowers friction during transmission, and requires less effort to rotate the drive ring. It can more efficiently convert circumferential rotation into axial movement, making it especially suitable for fruit puree extrusion scenarios that require frequent operation, thus improving ease of use.

[0052] The protrusions and spiral grooves make point or line contact, resulting in lower pressure per unit area and lower frictional loss in the contact area. This leads to less structural deformation and wear after long-term use, maintaining stable transmission accuracy and extending the overall service life of the structure.

[0053] To facilitate the assembly of the drive ring, specifically to facilitate the installation of the protrusion 31 into the spiral groove, in this embodiment, the discharge pipe 2 includes a first pipe body and a second pipe body that are coaxially arranged and connected to each other, and the spiral groove 21 is disposed between the first pipe body and the second pipe body; the discharge pipe 2 adopts a split structure, which forms a spiral groove structure after splicing, which reduces production costs and facilitates the assembly of the drive ring.

[0054] To ensure the axial movement of the extrusion valve 4 and prevent circumferential rotation, in this embodiment, a strip-shaped guide groove 403 is provided on the extrusion valve 4, with its open end facing the discharge pipe. The length direction of the strip-shaped guide groove 403 is parallel to the movement direction of the extrusion valve 4. At the same time, a limiting protrusion 22 is provided at the end of the discharge pipe 2. The cross-section of the limiting protrusion 22 is basically the same as the cross-sectional shape of the strip-shaped guide groove 403. It can be axially inserted into the strip-shaped guide groove 403, thereby achieving radial limiting of the extrusion valve, that is, allowing its axial movement but not radial rotation. The length direction of the strip-shaped guide groove is parallel to the movement direction of the extrusion valve. The high matching degree between the limiting protrusion and the cross-section of the guide groove can provide precise guidance for the axial movement of the extrusion valve, ensuring that the extrusion valve always moves smoothly along the preset trajectory, avoiding deviation, ensuring the alignment accuracy of the valve plug and the discharge port, and improving the reliability of the discharge control. After the limiting protrusion is inserted into the strip guide groove, it restricts the circumferential rotational freedom of the extrusion valve radially, so that the extrusion valve can only move axially. This effectively avoids the problem of the extrusion valve rotating synchronously with the drive ring, ensuring that the relative position of the extrusion port, guide hole, and discharge port is stable, and the discharge shape and direction are always controllable.

[0055] In this embodiment, a first limiting protrusion 43 is provided on the side wall of the extrusion valve 4, and a first annular groove 302 is provided on the inner wall of the first end of the drive ring 3. The first annular groove 302 can accommodate the radial insertion of the first limiting protrusion 43, thereby realizing the circumferential rotation and axial limiting between the extrusion valve 4 and the drive ring 3. Through the above structural arrangement, the drive ring 3 can rotate axially relative to the extrusion valve 4, while ensuring that the two are relatively stationary in the axial direction, that is, they can move synchronously in the axial direction to ensure the radial accuracy of the extrusion valve 4. Its structure is simple and compact, and the manufacturing cost is low.

[0056] In this embodiment, there are multiple first limiting protrusions 43, which are evenly distributed circumferentially, preferably two.

[0057] Preferably, a clearance groove 303 is provided on the inner wall of the drive ring 3. The first end of the clearance groove 303 communicates with the first annular groove 302, and the second end of the clearance groove 303 extends along the axial direction of the drive ring 3 and penetrates to the outside of the drive ring. The length of the clearance groove 303 is parallel to the axial direction of the drive ring. At the same time, the width of the clearance groove 303 is greater than or equal to the width of the first limiting protrusion 43. When the first limiting protrusion 43 is located inside the clearance groove 303, the clearance groove 303 and the first limiting protrusion 43 can achieve axial relative sliding, that is, at this time, the extrusion valve 4 can... The valve can move axially relative to the drive ring 3 and can disengage; the second end of the clearance groove extends through the drive ring along the axis and its width is adapted to the first limiting protrusion, so that the extrusion valve can be quickly assembled by axial insertion and rotation locking without complicated alignment operations; when disassembling, simply rotate in the opposite direction to align the first limiting protrusion with the clearance groove, and the extrusion valve can be directly pulled out axially; when it is necessary to clean or repair the extrusion valve or the inside of the drive ring, the parts can be quickly disassembled without the need for professional tools, and users can complete the maintenance operation themselves, reducing after-sales maintenance costs and downtime.

[0058] To improve the operational stability of the drive ring, a friction part is provided on the outer wall of the drive ring 3, or a lever or other structure is provided.

[0059] In this application, a sleeve 42 is provided on the extrusion valve 4. The sleeve 42 can be axially inserted into the guide hole 20 to achieve sliding fit. An extrusion channel 401 is formed inside the sleeve 42. The open end of the extrusion channel 401 faces the discharge port 200, and the other end is connected to the extrusion port 402 to form a discharge path. In this embodiment, the axis of the guide hole 20 is parallel to the axis of the discharge port 200, and the diameter of the guide hole 20 is larger than the diameter of the discharge port 200. A valve core rod 41 facing the discharge port 200 is provided at the end of the sleeve 42, and a valve plug 411 is fixed to the end of the valve core rod 41. In this embodiment, the valve core rod 41 is disposed inside the sleeve 42, and the valve core rod 41 is coaxial with the discharge port 200 and parallel to the sleeve 42.

[0060] The extrusion channel inside the sleeve forms a coaxial and continuous discharge path with the extrusion port and discharge port, avoiding the problem of uneven flow resistance of fruit pulp raw materials caused by channel bends or misalignments in traditional structures. The raw materials flow more smoothly in the channel, and the discharge speed is stable. The valve core rod is coaxially set with the discharge port, and the sleeve and guide hole slide to guide, so that the valve plug can be accurately aligned with the center of the discharge port. In the closed state, the valve plug can completely fit the discharge port to achieve a seal, effectively preventing fruit pulp leakage. When open, the gap between the valve plug and the discharge port is uniform, and the discharge is more regular.

[0061] To enhance automation, this application includes an axially sliding trigger block 52 mounted on the side wall of the discharge pipe 2. The side wall of the trigger block 52 has a second limiting protrusion 521, and the inner wall of the second end of the drive ring 3 has a second annular groove 301. The second annular groove 301 accommodates the radial insertion of the second limiting protrusion 521. The drive ring's movement drives the trigger block 52 to move axially. Simultaneously, a trigger part 522 is located at the end of the trigger block 52, triggering a detection switch on the container to achieve automatic extrusion. Through the linkage design of the drive ring and the trigger block, the mechanical motion of the drive ring is directly converted into a trigger signal: when the drive ring drives the extrusion valve to complete axial movement and achieve discharge, it simultaneously drives the trigger block to trigger the detection switch on the container. The detection switch can then control the piston movement within the container, achieving a fully automated process of one-button start-automatic discharge-automatic stop without manual intervention, significantly improving ease of use and flexibility, and providing a superior user experience.

[0062] To facilitate the installation of the second annular protrusion, the aforementioned clearance groove extends axially and connects to the second annular groove 301.

[0063] For ease of overall cleaning and maintenance, in another embodiment of this application, the discharge pipe 2 is detachably installed on the side wall of the container 1.

[0064] See Figures 11-13 An interface 11 communicating with the interior of the container is provided on the side wall of the container 1, and the discharge pipe 2 is detachably installed on the interface 11. In order to achieve quick installation and removal, the discharge pipe 2 is installed on the interface 11 by a snap-fit ​​assembly, and a sealing ring is provided between the discharge pipe and the interface. Specifically, multiple protrusions are provided on the side wall of the interface 11 to form a locking block 111, and the discharge pipe 2 is provided with a locking groove 201 corresponding to the locking block 111. When connecting, the locking groove 201 on the discharge pipe 2 is aligned with the locking block 111 of the interface 11 and inserted axially. Then, by rotating the discharge pipe 2, it is locked and fixed on the interface 11, realizing quick connection with the container 1. Through the above structural settings, the discharge pipe 2 can be quickly installed and removed, which is convenient for daily cleaning and maintenance.

[0065] In this embodiment, the valve core rod 41 is coaxially arranged with the discharge pipe 2.

[0066] Meanwhile, a sealing cap can be installed on the interface 11. When the discharge pipe 2 is in the disassembled state, the sealing cap can be fixed on the interface to prevent foreign objects from entering the container.

[0067] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
