Description

Technical Field

[0001] This utility model relates to the field of kitchenware technology, specifically to a dehydration device for vegetables. Background Technology

[0002] During the pickling process of some vegetables, since the vegetables themselves are rich in water, it is necessary to squeeze out the excess water to avoid affecting the subsequent pickling effect. In existing technology, the vegetables are usually squeezed by holding them with both hands, or the vegetables are wrapped in gauze and squeezed and rotated to squeeze out the water. Both of these methods are physically demanding for the user, especially when there are a lot of vegetables. These two methods cannot solve the problem of quickly squeezing out water from vegetables.

[0003] An existing patent (publication number: CN223025394U) discloses a water-squeezing device for vegetables, including an outer barrel body. A fixed frame is installed inside the outer barrel body. The lowest point of the fixed frame is located in the middle of the outer barrel body. The fixed frame has a liftable pressing plate inside. The pressing plate can squeeze the vegetables placed in the fixed frame, so that the water squeezed out of the vegetables falls to the bottom of the outer barrel body.

[0004] In the process of using the above-mentioned patent, vegetables are placed on the filter plate inside the outer barrel, and the pressing plate contacts the vegetables. After the top cover is fastened to the outer barrel, pressure is applied to the pressing plate by a spring to squeeze out the water from the vegetables. As the spacing between the vegetables gradually becomes closer, the required force gradually increases, which is quite laborious. Although the screw rotation pressing method solves the problem of the required force gradually increasing as the spacing between the vegetables gradually becomes closer, in the initial stage, because the spacing between the vegetables is large, the number of rotations is more, which is not as time-saving as the screw rotation pressing method. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a water-squeezing device for vegetables, which has the advantage of rapid water squeezing and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dewatering device for vegetables, comprising an outer cylinder, a pressure plate disposed inside the outer cylinder, a top plate installed on the top of the inner wall of the outer cylinder, a central screw rotatably connected to the upper surface of the pressure plate, the central screw penetrating the top plate, a bearing plate fixed to the upper surface of the top plate, four incomplete threaded sleeves corresponding to the central screw slidably connected to the inner wall of the bearing plate, a wedge fixed to the outer surface of each incomplete threaded sleeve, a threaded cylinder fixed to the upper surface of the top plate, a threaded sleeve fitted onto the outer surface of the top end of the threaded cylinder, and the inner wall of the top end of the threaded sleeve being a conical surface corresponding to the wedge.

[0007] Furthermore, a bearing cylinder is connected to the threaded sleeve on the bottom outer surface of the outer cylinder, and drainage ports are equidistantly opened on the outer surface of the bearing cylinder.

[0008] The above solution involves a threaded connection between the support cylinder and the outer cylinder, allowing users to unscrew the support cylinder from the bottom of the outer cylinder and empty the vegetables inside after squeezing out the water.

[0009] Furthermore, the upper surface of the bearing plate is provided with multiple sliding grooves, and the bottom surface of each wedge is fixed with a slider, which is slidably connected to the corresponding sliding groove.

[0010] With the above scheme, the sliding of the slider in the groove provides guidance for the movement of the wedge, ensuring that the wedge can stably move closer to or away from the central screw in the horizontal direction, avoiding the wedge from shifting or getting stuck during the movement, thereby ensuring the fit between the incomplete threaded sleeve and the central screw.

[0011] Furthermore, multiple telescopic rods are fixedly installed on the inner wall of the bearing plate, and the other end of each telescopic rod is fixed to its corresponding wedge. A return spring is installed on the outer surface of each telescopic rod, and the other end of each return spring is fixed to its corresponding wedge.

[0012] With the above scheme, when the threaded sleeve moves downward, its conical surface will squeeze the wedge, causing the wedge to drive the incomplete threaded sleeve to move towards the central screw. At this time, the telescopic rod is stretched, and the return spring stores energy. When the threaded sleeve moves upward, the elastic force of the return spring will pull the wedge to drive the incomplete threaded sleeve to return to its original position, thus separating the incomplete threaded sleeve from the central screw.

[0013] Furthermore, a fixing ring is fixed to the inner wall of the top of the outer cylinder, and multiple slots are circumferentially formed on the upper surface of the fixing ring. Multiple corresponding inserts are fixed to the bottom surface of the top plate, and the inserts are inserted into the slots.

[0014] With the above scheme, the fixing ring and the top plate can be quickly positioned and installed by inserting the plug and slot, which facilitates the quick alignment of the relative position of the top plate and the outer cylinder during device assembly or maintenance. At the same time, after the plug is inserted into the slot, it can play a circumferential limiting role on the top plate, preventing the top plate from rotating inside the outer cylinder and ensuring the stable operation of components such as the central screw.

[0015] Furthermore, the bottom surface of the pressure plate is fixed with multiple extrusion protrusions, which are distributed radially.

[0016] The above scheme forms a drainage groove between adjacent extrusion ridges. By setting the extrusion ridges, the contact pressure with the vegetables can be increased when the pressure plate descends to extrude the vegetables, thereby improving the water extrusion efficiency. At the same time, the drainage groove can quickly guide the extruded water to the edge of the pressure plate, preventing water from accumulating at the bottom of the pressure plate and affecting the subsequent extrusion effect.

[0017] Furthermore, the upper surface of the pressure plate is fixed with a plurality of circumferentially arranged mounting grooves, and a rod is inserted into the inner wall of the mounting groove, the rod penetrating the top plate.

[0018] The above solution guides the lifting and lowering of the pressure plate, preventing it from tilting under the influence of the central screw. This ensures the pressure plate remains horizontal and in uniform contact with the vegetables, avoiding uneven pressure on the vegetables due to pressure plate tilt, which would affect the squeezing effect.

[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0020] This vegetable dewatering device uses a central screw to drive a pressure plate into direct contact with the vegetables. Then, a rotating threaded sleeve causes its conical surface to press against a wedge, moving an incompletely threaded sleeve towards and engaging with the central screw. The central screw is then rotated, and the threaded engagement between the incompletely threaded sleeve and the central screw drives the pressure plate to descend continuously, achieving deep dewatering of the vegetables. By combining the rapid initial contact of direct pressure with the labor-saving continuous dewatering via threaded transmission, this device effectively solves the problems of excessive effort or too many rotations in the initial stage of traditional devices, significantly improving the efficiency and convenience of vegetable dewatering.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Please see Figure 1 - Figure 5 This embodiment of a dehydrating device for vegetables includes an outer cylinder 1, a pressure plate 2 inside the outer cylinder 1, a top plate 3 installed at the top of the inner wall of the outer cylinder 1, a central screw 4 rotatably connected to the upper surface of the pressure plate 2, the central screw 4 penetrating the top plate 3, a bearing plate 5 fixed to the upper surface of the top plate 3, four incomplete threaded sleeves 6 corresponding to the central screw 4 slidably connected to the inner wall of the bearing plate 5, a wedge 7 fixed to the outer surface of each incomplete threaded sleeve 6, a threaded cylinder 8 fixed to the upper surface of the top plate 3, a threaded sleeve 9 sleeved on the outer surface of the top end of the threaded cylinder 8, and the inner wall of the top end of the threaded sleeve 9 being a conical surface corresponding to the wedge 7.

[0030] Please see Figure 2 , Figure 3 and Figure 5 The outer cylinder 1 has a bearing cylinder 10 threadedly fitted onto the bottom outer surface. The outer surface of the bearing cylinder 10 has drainage holes equidistantly spaced. The bearing cylinder 10 is threadedly connected to the outer cylinder 1, making it easy for the user to unscrew the bearing cylinder 10 from the bottom of the outer cylinder 1 after squeezing out the water and pour out the vegetables placed inside. The upper surface of the bearing plate 5 has multiple sliding grooves. The bottom surface of each wedge 7 is fixed with a slider 11. The slider 11 is slidably connected to the corresponding sliding groove. The sliding of the slider 11 in the sliding groove provides guidance for the movement of the wedge 7, ensuring that the wedge 7 can stably move closer to or away from the central screw 4 in the horizontal direction, avoiding the wedge 7 from shifting or getting stuck during the movement, thereby ensuring the fit between the incomplete threaded sleeve 6 and the central screw 4.

[0031] Please see Figure 2 , Figure 4 and Figure 5Multiple telescopic rods 12 are fixedly installed on the inner wall of the bearing plate 5. The other end of each telescopic rod 12 is fixed to its corresponding wedge 7. A return spring 13 is installed on the outer surface of each telescopic rod 12. The other end of each return spring 13 is fixed to its corresponding wedge 7. When the threaded sleeve 9 moves downward, its conical surface will squeeze the wedge 7, causing the wedge 7 to drive the incomplete threaded sleeve 6 to move towards the central screw 4. At this time, the telescopic rod 12 is stretched, and the return spring 13 stores energy. When the threaded sleeve 9 moves upward, the elastic force of the return spring 13 will pull the wedge 7 to drive the incomplete threaded sleeve 6 to return to its original position, thus achieving the desired effect. The threaded sleeve 6 is completely disengaged from the central screw 4. A fixing ring is fixed to the inner wall of the top of the outer cylinder 1. Multiple slots are circumferentially opened on the upper surface of the fixing ring. Multiple corresponding insert blocks 14 are fixed to the bottom surface of the top plate 3. The insert blocks 14 are inserted into the slots. The fixing ring and the top plate 3 are quickly positioned and installed through the insertion of the insert blocks 14 and the slots. This facilitates quick alignment of the relative positions of the top plate 3 and the outer cylinder 1 during device assembly or maintenance. At the same time, after the insert blocks 14 are inserted into the slots, they can play a circumferential limiting role on the top plate 3, preventing the top plate 3 from rotating inside the outer cylinder 1 and ensuring the stable operation of components such as the central screw 4.

[0032] Please see Figure 2 , Figure 4 and Figure 5 The bottom surface of the pressure plate 2 is fixed with multiple extrusion protrusions 15, which are radially distributed. Drainage grooves are formed between adjacent extrusion protrusions 15. By setting the extrusion protrusions 15, the contact pressure with the vegetables can be increased when the pressure plate 2 descends to extrude the vegetables, thereby improving the water extrusion efficiency. At the same time, the drainage grooves can quickly guide the extruded water to the edge of the pressure plate 2, preventing water from accumulating at the bottom of the pressure plate 2 and affecting the subsequent extrusion effect. The upper surface of the pressure plate 2 is fixed with multiple circumferentially arranged mounting grooves 16. Insert rods 17 are inserted into the inner wall of the mounting grooves 16 and penetrate the top plate 3. The setting of the insert rods 17 can guide the lifting and lowering of the pressure plate 2, preventing the pressure plate 2 from tilting under the drive of the central screw 4, ensuring that the pressure plate 2 always maintains a horizontal state and makes uniform contact with the vegetables, and avoiding uneven force on the vegetables due to the tilting of the pressure plate 2, which would affect the water extrusion effect.

[0033] It should be noted that after squeezing out the water and removing the vegetables, the inside of the device should be rinsed with clean water to remove any remaining vegetable residue, in order to prevent bacteria from growing and affecting the next use.

[0034] The working principle of the above embodiment is as follows: First, put the vegetables to be squeezed into the outer cylinder 1, and then manually press down the central screw 4. At this time, the central screw 4 drives the pressure plate 2 to descend rapidly until the squeezing protrusion 15 on the bottom surface of the pressure plate 2 contacts the surface of the vegetables. This process uses direct pressing to achieve rapid contact between the pressure plate 2 and the vegetables, avoiding the problem of too many turns in the initial stage of traditional screw rotation.

[0035] Next, rotate the threaded sleeve 9. Since the threaded sleeve 9 is threadedly connected to the threaded cylinder 8, as it rotates, the threaded sleeve 9 moves downward along the threaded cylinder 8. The conical surface of its inner wall at the top gradually presses against the wedge 7. Under the thrust of the conical surface, the wedge 7 slides along the groove on the bearing plate 5 towards the central screw 4, simultaneously driving the incomplete threaded sleeves 6 to move synchronously. When the inner walls of the four incomplete threaded sleeves 6 are completely in contact with the outer surface of the central screw 4, a complete threaded fit structure is formed. Afterward, the user rotates the central screw 4. Since the central screw 4 is rotatably connected to the pressure plate 2, and the pressure plate 2 cannot rotate under the guidance of the insertion rod 17, the rotation of the central screw 4 is converted into the downward linear motion of the pressure plate 2. As the central screw 4 continues to rotate, the pressure plate 2 continuously applies pressure to the vegetables. Under the pressure of the squeezing action, the water in the vegetables is squeezed out. The squeezed water flows to the edge of the pressure plate 2 through the drainage groove between the squeezing protrusions 15, and then drips to the bottom of the outer cylinder 1 and is discharged through the drain port on the bearing cylinder 10. After the vegetables are squeezed out, the user rotates the threaded sleeve 9 in the opposite direction. The threaded sleeve 9 moves upward along the threaded cylinder 8, and the squeezing force of the cone on the wedge block 7 disappears. At this time, the return spring 13 on the outer surface of the telescopic rod 12 releases its elastic force, pulls the wedge block 7 and drives the incomplete threaded sleeve 6 to move away from the central screw 4, so that the incomplete threaded sleeve 6 is disengaged from the central screw 4. Then the user can pull the central screw 4 upward to lift the pressure plate 2 to the initial position. Finally, unscrew the bearing cylinder 10 at the bottom of the outer cylinder 1 to take out the squeezed vegetables.
