Description

Technical Field

[0001] This utility model relates to the field of food testing technology, specifically to a rapid testing device for analyzing the sweetness of food. Background Technology

[0002] As people's living standards continue to improve, when purchasing fruits, people not only pay attention to their appearance quality such as size, color, shape, and surface defects, but also attach great importance to their internal quality such as sugar content and acidity.

[0003] Chinese Patent Application No. 202322383129.2 discloses a sampling device for detecting the sweetness of fruits and vegetables. This device enables rapid juicing of fruits and vegetables with low water content, thus efficiently detecting their sugar content. In this invention, the extrusion block moves downwards, compressing the fruit and vegetable sample stored in the juicing chamber. Simultaneously, the rotation of the extrusion block continuously squeezes out the juice from the sample, which drips through the discharge chamber and the lower wall outlet into the drip chamber. The results are then detected by the detector and displayed on a screen. This invention, with its rotatable extrusion block, rapidly extracts juice from fruits and vegetables with low water content through compression and rotation, eliminating the need for manual juicing, significantly reducing the time required for sugar content detection, and improving the efficiency of fruit and vegetable sugar content testing.

[0004] However, the above technical solution still has some drawbacks in use. For example, since the juicing chamber is located on the juicing box, the juicing chamber and the juicing box are designed as a single fixed unit. This makes it inconvenient for users to remove the sample from the juicing chamber after juicing, and it is also inconvenient for users to clean the juicing chamber, thus limiting its ease of use. Utility Model Content

[0005] The purpose of this utility model is to provide a rapid detection device for food sweetness analysis, which solves the certain defects of the above-mentioned technical solutions in use. For example, since the juicing chamber is opened on the juicing box, the juicing chamber and the juicing box are designed as an integral fixed unit. This makes it inconvenient for the user to take out the sample from the juicing chamber after the sample is juiced, and it is also inconvenient for the user to clean the juicing chamber, thus resulting in limited ease of use.

The pressing mechanism consists of a sealing component, a transmission component, a pressing component, a limiting component and a filtering component. The transmission component includes a rack and a drive gear. The rack is connected to the pressing component and meshes with the drive gear. A driven gear meshes with the outer side of the drive gear. Both the drive gear and the driven gear are rotatably connected to the bracket.

[0007] As a preferred embodiment of the above technical solution, the disassembly and assembly mechanism includes a threaded hole, an external thread, and a pressing cylinder. The threaded hole is formed on the bracket, and the external thread is provided on the pressing cylinder. The pressing cylinder is threadedly engaged with the threaded hole through the external thread. A liquid outlet pipe is provided at the bottom of the pressing cylinder, and the position of the liquid outlet pipe corresponds to the dripping cavity.

[0008] As a preferred embodiment of the above technical solution, the enclosed assembly includes two through holes and a rotating shaft. The two through holes are both opened on the bracket and are respectively distributed on both sides of the threaded hole. The two ends of the two rotating shafts are rotatably connected to the inside of the two through holes through bearing seats. One end of the two rotating shafts extends out of the through holes and is fixedly connected to the driving gear and the driven gear respectively.

[0009] As a preferred embodiment of the above technical solution, each of the two rotating shafts is fixedly connected to a connecting plate, each of the two connecting plates is fixedly connected to a top plate, and each of the two top plates is fixedly connected to a sealing plate. The two connecting plates are respectively distributed inside the two through holes. Semi-circular holes are provided on both the two top plates and the two sealing plates. The dimensions of the two sealing plates are adapted to the inner diameter of the pressing cylinder.

[0010] As a preferred embodiment of the above technical solution, the limiting component includes a support rod, a fixing plate, and a limiting plate. The support rod is fixedly connected to the top end of the bracket, the fixing plate is fixedly connected to the top end of the support rod, and the limiting plate is fixedly connected to the support rod.

[0011] As a preferred embodiment of the above technical solution, the pressing assembly includes an electric push rod, a sliding plate, and a spring. The electric push rod is fixedly connected to the top of the fixed plate, and the output shaft of the electric push rod passes through the fixed plate and is fixedly connected to the sliding plate. The sliding plate is slidably connected to the support rod. One end of the spring is fixedly connected to the bottom of the sliding plate, and the other end of the spring is fixedly connected to the top of the bracket. The rack is fixedly connected to the sliding plate.

[0012] As a preferred embodiment of the above technical solution, a connecting rod is fixedly connected to the bottom of the slide plate, and a pressure block is fixedly connected to the end of the connecting rod away from the slide plate. The position of the pressure block corresponds to the pressing cylinder, and the size of the pressure block is adapted to the size of the pressing cylinder. The diameter of the connecting rod is adapted to the semi-circular hole on the top plate and the sealing plate.

[0013] As a preferred embodiment of the above technical solution, the filter assembly includes a mounting ring, a plurality of bolt holes, a filter screen, and a plurality of bolts. The mounting ring is fixedly connected to the inner wall of the pressing cylinder. Each bolt hole is opened on the mounting ring and is equidistant from each other.

Each bolt passes through each through hole and is threaded into the inner side of each bolt hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, through the design of a base plate, detector, bracket, disassembly and assembly mechanism, and pressing mechanism, allows the sample to be tested to be placed on a filter screen inside the pressing cylinder. Then, the electric push rod is activated, causing a sliding plate to move via a support rod. This movement of the sliding plate, through a connecting rod, moves the pressing block, which slowly moves into the pressing cylinder. The pressing block then squeezes the sample on the filter screen, squeezing out the water. During this process, the sliding plate movement also drives a rack, which in turn drives a drive gear. This drive gear, in turn, drives a driven gear, which in turn drives two rotating shafts. These shafts, in turn, drive a connecting plate, which in turn drives a top plate, which in turn drives a sealing plate. When the sealing plate and top plate reach a perpendicular position, the sealing plate inserts into the cylinder. Inside the pressing cylinder, both the sealing plate and the top plate seal the cylinder. The water from the pressed sample drips through the outlet pipe into the dripping chamber. At this point, the detector can detect the sweetness of the sample and display it on the screen. When it is necessary to remove the sample from the pressing cylinder or to clean the pressing cylinder, the pressing cylinder can be rotated to separate it from the threaded hole. After separating the pressing cylinder from the threaded hole, the bolt can be rotated to separate the bolt on the filter screen from the bolt hole, thus disassembling the filter screen. This allows for the detection of the sweetness of food while also facilitating the disassembly and assembly of the pressing cylinder for easy cleaning. Furthermore, the pressing cylinder can be sealed during pressing to prevent juice from overflowing during sample pressing. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] like Figures 1-5 As shown, a rapid detection device for food sweetness analysis includes a base plate 1, a detector 2 mounted on the base plate 1, a display screen and a drip chamber mounted on the detector 2, a bracket 3 fixedly connected to the base plate 1, and a disassembly and assembly mechanism and a pressing mechanism mounted on the bracket 3. The pressing mechanism consists of a sealing component, a transmission component, a pressing component, a limiting component and a filtering component. The transmission component includes a rack 11 and a drive gear 12. The rack 11 is connected to the pressing component and meshes with the drive gear 12. A driven gear 13 meshes with the outer side of the drive gear 12. Both the drive gear 12 and the driven gear 13 are rotatably connected to the bracket 3.

[0030] In use, the user can install the pressing component through the disassembly and assembly mechanism. Then, the pressing component can be used to press the sample to extract the water. After that, the sweetness of the sample is detected by the detector 2. In this process, the movement of the pressing component will drive the rack 11 to move. The movement of the rack 11 will cause the drive gear 12 to rotate. The rotation of the drive gear 12 will drive the driven gear 13 to rotate. At this time, with the cooperation of the drive gear 12 and the driven gear 13, the sealing component works.

[0031] Furthermore, the disassembly and assembly mechanism includes a threaded hole 21, an external thread 22, and a pressing cylinder 23. The threaded hole 21 is located on the bracket 3, and the external thread 22 is located on the pressing cylinder 23. The pressing cylinder 23 is threadedly engaged with the threaded hole 21 through the external thread 22. A liquid outlet pipe is provided at the bottom of the pressing cylinder 23, and the position of the liquid outlet pipe corresponds to the dripping cavity. The pressing cylinder 23 can be installed on the bracket 3 through the engagement of the external thread 22 and the threaded hole 21. When it is necessary to clean the pressing cylinder 23, it can be disassembled by rotating the pressing cylinder 23 in the reverse direction, which makes it convenient for the user to take out the sample from the pressing cylinder 23 and clean the pressing cylinder 23.

[0032] Furthermore, the sealing assembly includes two through holes 31 and rotating shafts 32. Both through holes 31 are formed on the bracket 3 and are respectively distributed on both sides of the threaded hole 21. The two ends of the two rotating shafts 32 are rotatably connected to the inside of the two through holes 31 via bearing seats. One end of each rotating shaft 32 extends out of the through holes 31 and is fixedly connected to the driving gear 12 and the driven gear 13, respectively. Connecting plates 33 are fixedly connected to both rotating shafts 32, and top plates 34 are fixedly connected to both connecting plates 33. Sealing plates 35 are fixedly connected to both top plates 34. The two connecting plates 33 are respectively distributed inside the two through holes 31. Both the two top plates 34 and the two sealing plates 35 have... The semi-circular hole and the dimensions of the two sealing plates 35 are adapted to the inner diameter of the pressing cylinder 23. When the driving gear 12 and the driven gear 13 rotate, the two rotating shafts 32 will be driven to rotate by the driving gear 12 and the driven gear 13. At the same time, due to the influence of the driving gear 12 and the driven gear 13, the rotation directions of the two rotating shafts 32 will be opposite. The rotation of the two rotating shafts 32 will drive the two connecting plates 33, the top plate 34 and the sealing plate 35 to move. After the two sealing plates 35 and the top plate 34 move to a certain position, the sealing plate 35 will be inserted into the pressing cylinder 23. At the same time, the top plate 34 and the sealing plate 35 will seal the pressing cylinder 23, thereby avoiding the problem of juice overflow when pressing the sample.

[0033] Furthermore, the limiting assembly includes a support rod 41, a fixing plate 42, and a limiting plate 43. The support rod 41 is fixedly connected to the top of the bracket 3, the fixing plate 42 is fixedly connected to the top of the support rod 41, and the limiting plate 43 is fixedly connected to the support rod 41. When the slide plate 52 moves, the support rod 41 can limit the slide plate 52, so that the pressing block 55 on the slide plate 52 can be accurately pressed into the pressing cylinder 23.

[0034] Furthermore, the pressing assembly includes an electric push rod 51, a sliding plate 52, and a spring 53. The electric push rod 51 is fixedly connected to the top of the fixed plate 42. The output shaft of the electric push rod 51 passes through the fixed plate 42 and is fixedly connected to the sliding plate 52. The sliding plate 52 is slidably connected to the support rod 41. One end of the spring 53 is fixedly connected to the bottom of the sliding plate 52, and the other end of the spring 53 is fixedly connected to the top of the bracket 3. The rack 11 is fixedly connected to the sliding plate 52. A connecting rod 54 is fixedly connected to the bottom of the sliding plate 52. A pressure block 55 is fixedly connected to the end of the connecting rod 54 away from the sliding plate 52. The position of the pressure block 55 is relative to the pressing cylinder 23. Correspondingly, the size of the pressing block 55 is adapted to the size of the pressing cylinder 23, and the diameter of the connecting rod 54 is adapted to the semi-circular holes on the top plate 34 and the sealing plate 35. The sliding plate 52 can be moved by the electric push rod 51 through the support rod 41. The movement of the sliding plate 52 drives the connecting rod 54 to move, and the movement of the connecting rod 54 drives the pressing block 55 to move. At the same time, the sliding plate 52 will squeeze the spring 53, and the pressing block 55 will extend into the pressing cylinder 23. Then, with the cooperation of the filter screen 63, the sample will be pressed. At the same time, the movement of the sliding plate 52 will drive the sealing component to move with the cooperation of the transmission component, thereby sealing the pressing cylinder 23.

[0035] Furthermore, the filter assembly includes a mounting ring 61, several bolt holes 62, a filter screen 63, and several bolts 64. The mounting ring 61 is fixedly connected to the inner wall of the pressing cylinder 23. Each bolt hole 62 is opened on the mounting ring 61, and each bolt hole 62 is equidistantly distributed. The filter screen 63 is disposed on the mounting ring 61, and the filter screen 63 has the same number of through holes as the bolt holes 62, and the positions of the through holes correspond to those of the bolt holes 62. Each bolt 64 passes through each through hole and is threaded to the inside of each bolt hole 62. The filter screen 63 can be disassembled by removing the bolts 64 from the bolt holes 62, thereby facilitating the cleaning of the filter screen 63.

[0036] Working principle: The filter screen 63 is installed by the engagement of bolt 64 and bolt hole 62. Then, the pressing cylinder 23 is installed on the bracket 3 by the engagement of external thread 22 and threaded hole 21. The sample to be tested is then placed on the filter screen 63 inside the pressing cylinder 23. The electric push rod 51 is then activated, which moves the sliding plate 52 via the support rod 41. The movement of the sliding plate 52 moves the connecting rod 54 and rack 11, which in turn moves the pressing block 55. Simultaneously, the sliding plate 52 compresses the spring 53, causing the pressing block 55 to extend into the pressing cylinder 23. The sample is then pressed by the filter screen 63. The movement of the rack 11 causes the drive gear 12 to rotate. The rotation of wheel 12 drives the driven gear 13 to rotate. The rotation of the driving gear 12 and the driven gear 13 will drive the two rotating shafts 32 to rotate. The two rotating shafts 32 will rotate in opposite directions. The rotation of the two rotating shafts 32 will drive the two connecting plates 33, the top plate 34 and the sealing plate 35 to move. After the two sealing plates 35 and the top plate 34 move to a certain position, the sealing plate 35 will be inserted into the pressing cylinder 23. At the same time, the top plate 34 and the sealing plate 35 will seal the pressing cylinder 23, thereby avoiding the problem of juice overflowing when pressing the sample. The juice after being pressed drips into the dripping chamber through the liquid outlet pipe in the pressing cylinder 23. At this time, the detector 2 can detect the sweetness of the juice and then display it on the display screen.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
