Description

Technical Field

[0001] This utility model relates to the technical field of sauce extrusion devices, and in particular to an auxiliary piston rod reset structure and a sauce extrusion device. Background Technology

[0002] Traditional push-type sauce extruders rely heavily on manual pressing, lacking a precise stroke control module. This results in significant fluctuations in the amount of sauce extruded per batch, failing to meet the precise requirements for sauce dosage in baking, cooking, and other scenarios. To address these issues, the applicant previously filed CN202420101798.8 for a sauce extruder and its extrusion structure, and CN202520598083.2 for an adjustable extrusion structure and device. These applications achieve extrusion by pressing a handle and can control the extrusion amount with minimal fluctuations.

[0003] However, during the technical iteration of CN202520598083.2, which describes an adjustable extrusion structure and device, it was discovered that when the spring on the piston rod bounces up, it presses against the spring plate, causing the piston rod to be obliquely stuck by the spring plate. This results in the piston rod being able to be pulled upwards to reset, but the reset process is not smooth, affecting the user experience. Utility Model Content

[0004] The main purpose of this utility model is to provide an auxiliary piston rod reset structure and a squeezing device, which aims to effectively solve the problem of uneven piston rod reset process mentioned in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: This utility model discloses an auxiliary piston rod reset structure, including a housing, a piston rod, an operating handle, a spring element, and a spring pressure plate. The piston rod passes vertically through the housing, and the spring pressure plate and spring element are both fitted onto the piston rod. The operating handle is rotatably connected to the housing. The auxiliary piston rod reset structure further includes: An auxiliary reset handle is rotatably connected to the housing; the auxiliary reset handle includes an operating part and a pressing part, the operating part being located outside the housing, and the pressing part being located above the spring pressure plate; When the auxiliary reset handle is in the independent rotation state, the pressing part rotates and presses down on multiple positions of the spring pressure plate so that the spring pressure plate remains perpendicular to the piston rod.

[0006] Compared with the prior art, the auxiliary piston rod reset structure added in this application has an auxiliary reset handle that can be rotated independently and pressed down on multiple positions of the spring pressure plate, so that the spring pressure plate is kept perpendicular to the piston rod, avoiding the piston rod being obliquely stuck by the spring pressure plate due to the spring being pushed up, thereby reducing the resistance of the spring pressure plate to the piston rod, facilitating the piston rod to be pulled upward to reset, and the reset process is smooth, improving the user experience.

[0007] In one embodiment, the pressing part includes a pressing main part, a first pressing sub-part, and a second pressing sub-part. The first pressing sub-part and the second pressing sub-part are respectively connected to both ends of the pressing main part, so that the lower side of the pressing part forms a U-shaped pressing area.

[0012] In one embodiment, the auxiliary reset handle has an individual rotation state and a synchronous rotation state; When the auxiliary reset handle is in a synchronous rotation state, the linkage part of the operating handle rotates and presses down on a position of the spring pressure plate, so that the spring pressure plate drives the piston rod to move downward synchronously.

[0013] In one embodiment, the operating part has outwardly extending extensions on opposite sides, and the two extensions are on the same straight line.

[0018] To better illustrate this utility model, a further detailed description of this utility model is provided below with reference to the accompanying drawings.

[0019] If the terms "first" or "second" are used in this document to define the components, those skilled in the art should know that the use of "first" or "second" is merely for the convenience of describing this utility model and simplifying the description, and unless otherwise stated, the above terms have no special meaning.

[0020] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0021] Combination Figures 1 to 5As shown, this utility model discloses an auxiliary piston rod 2 reset structure, including a housing 1, a piston rod 2, an operating handle 3, a spring 4, and a spring pressure plate 5. The piston rod 2 passes vertically through the housing 1, and the spring pressure plate 5 and the spring 4 are both fitted onto the piston rod 2. The operating handle 3 is rotatably connected to the housing 1. The auxiliary piston rod 2 reset structure further includes an auxiliary reset handle 6, which is rotatably connected to the housing 1. The auxiliary reset handle 6 includes an operating part 610 and a pressing part 620. The operating part 610 is located outside the housing 1, and the pressing part 620 is located above the spring pressure plate 5. When the auxiliary reset handle 6 is in a rotating state, the pressing part 620 rotates and presses down on multiple positions of the spring pressure plate 5, so that the spring pressure plate 5 remains vertically positioned relative to the piston rod 2.

[0022] Specifically, the auxiliary piston rod 2 reset structure of this utility model is applied to a sauce extrusion device. During each sauce extrusion process, the linkage part 320 of the operating handle 3 presses down the spring plate 5 to a certain position, generating a linear downward pressure and a linear horizontal thrust on the spring plate 5. After receiving the linear downward pressure, the spring plate 5 moves downward along the piston rod 2. After receiving the linear horizontal thrust, the friction between the spring plate 5 and the piston rod 2 increases, causing the piston rod 2 to move downward along with the spring plate 5, thus realizing sauce extrusion. After each sauce extrusion operation, the spring 4 releases its elastic potential energy synchronously after the operating handle 3 is released, lifting the spring plate 5 and allowing the spring plate 5 and the operating handle 3 to automatically spring back to their initial positions for the next sauce extrusion operation.

[0023] When the squeezing device finishes squeezing the sauce and the piston rod 2 needs to be pulled upwards to reset, the user can operate the auxiliary reset handle 6's operating part 610 independently, allowing the auxiliary reset handle 6 to rotate independently relative to the housing 1. At this time, the pressing part 620 rotates and presses down on multiple positions of the spring pressure plate 5, so that the spring pressure plate 5 remains vertically positioned relative to the piston rod 2. This prevents the piston rod 2 from being obliquely jammed by the spring pressure plate 5 due to the spring member 4 being pushed up, thereby reducing the resistance of the spring pressure plate 5 to the piston rod 2, facilitating the upward pull of the piston rod 2 to reset, and ensuring a smooth reset process, thus improving the user experience. This application ensures that the spring pressure plate 5 is in a horizontal position (i.e., the spring pressure plate 5 remains vertically positioned relative to the piston rod 2 as mentioned above) by pressing down on multiple positions, without jamming the piston rod 2, so that the piston rod 2 can be easily pulled upwards to reset.

[0024] It should be noted that the multiple positions of the spring pressure plate 5 refer to multiple positions on the upper side of the spring pressure plate 5.

[0025] Regarding how to press down the spring plate 5 at multiple positions, in this embodiment, the pressing part 620 includes a pressing main part 621, a first pressing sub-part 622, and a second pressing sub-part 623. The first pressing sub-part 622 and the second pressing sub-part 623 are respectively connected to both ends of the pressing main part 621, so that the lower side of the pressing part 620 forms a U-shaped pressing area. With the above structure, when the pressing part 620 presses down the spring plate 5, the U-shaped pressing area will contact and press down at multiple positions on the upper side of the spring plate 5, thereby keeping the spring plate 5 perpendicular to the piston rod 2 and avoiding the oblique jamming situation caused by pressing down the spring plate 5 at a single position.

[0026] Furthermore, the pressing part 620 is also provided with a U-shaped groove; the piston rod 2 is located in the U-shaped groove so as to reserve a position for the piston rod 2 to pass through, and to make the U-shaped pressing area as close as possible to the piston rod 2, thereby ensuring that the spring pressure plate 5 is set vertically relative to the piston rod 2.

[0027] In this embodiment, the auxiliary reset handle 6 further includes a connecting rod 630. One end of the connecting rod 630 is connected to the operating part 610, and the other end of the connecting rod 630 is connected to the pressing part 620. The connecting rod 630 is rotatably connected to the housing 1. In this embodiment, the connecting rod 630 is used to connect the operating part 610 and the pressing part 620 so that when the operating part 610 is operated, the pressing part 620 can rotate synchronously.

[0028] In this embodiment, the connecting rod 630 is provided with a first mounting hole 631; the operating handle 3 is provided with a second mounting hole, which is coaxially arranged with the first mounting hole 631; the housing 1 is provided with a connecting shaft 10, which passes through the first mounting hole 631 and the second mounting hole. In this embodiment, the auxiliary reset handle 6 and the operating handle 3 are installed and connected by the connecting shaft 10, so that the auxiliary reset handle 6 and the operating handle 3 are rotatably connected to the housing 1; moreover, the shared connecting shaft 10 can reduce the number of accessories and costs.

[0029] Furthermore, the operating part 610 is located between the handle part 310 of the operating handle 3 and the piston rod 2, and the operating part 610 is located within the rotation range of the operating handle 3. The position of the operating part 610 is reasonably arranged to avoid the newly added operating part 610 occupying other space.

[0030] The auxiliary reset handle 6 has an independent rotation state and a synchronous rotation state. When the auxiliary reset handle 6 is in the synchronous rotation state, the linkage part of the operating handle 3 rotates and presses down on one position of the spring pressure plate 5, so that the spring pressure plate 5 drives the piston rod 2 to move downward synchronously, completing a single squeezing operation. Moreover, since the linkage part abuts against the spring pressure plate 5, the linkage part will first press down on the spring pressure plate 5 and drive the piston rod 2 to move downward, unaffected by the auxiliary reset handle 6.

[0031] In this embodiment, the operation part 610 is provided with outwardly extending extension parts 611 on opposite sides, and the two extension parts 611 are on the same straight line, so that the user can operate the auxiliary reset handle 6 by means of the extension parts 611.

[0032] This utility model also discloses a sauce extrusion device, which includes the auxiliary piston rod 2 reset structure as described above, and further includes: a cylinder 70 for storing sauce, the cylinder 70 having an installation end and a discharge end, the installation end being detachably connected to the housing 1; a discharge cover 80, which is detachably connected to the discharge end, the discharge cover 80 having a discharge port at the bottom; the outer periphery of the discharge port having a plurality of downwardly extending protruding steps.

[0033] The outer periphery of the discharge port has multiple downwardly extending protruding steps. The steps raise the position of the discharge port, and the bottoms of the multiple steps together provide a support surface, allowing the extrusion device to be placed vertically on a table for easy use.

[0034] Furthermore, the piston rod 2, the push plate, and the cylinder 70 are coaxially arranged, and the diameter of the push plate is similar to the inner diameter of the cylinder 70. This allows the piston rod 2 to be centered and squeeze the sauce out of the cylinder 7091.

[0035] Furthermore, the mounting end is snapped or threadedly connected to the bottom cover of the housing 1.

[0036] Furthermore, the discharge end is snap-fitted or threadedly connected to the discharge cover 80.

[0037] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
