Description

Technical Field

[0001] This utility model relates to the field of biological detection technology, and in particular to a sealed reaction card for visual detection of dragon fruit virus. Background Technology

[0002] As an important tropical fruit, dragon fruit is often threatened by viral diseases during its cultivation. Viral infections not only affect the growth and yield of dragon fruit, but also seriously reduce the quality and commercial value of the fruit. In order to effectively control the spread of diseases, early, rapid and accurate detection of dragon fruit viruses is crucial. At present, commonly used virus detection methods include molecular biological detection and immunological detection. These methods often require specific reaction conditions. Among them, precise control of reaction temperature and strict sealing of the reaction environment are key factors to ensure the accuracy and reliability of the test results.

[0003] Existing virus detection devices or reaction cards often require incubation in an external temperature-controlled environment during visual detection. This not only increases the complexity and cost of the detection equipment but also prolongs operation time and detection cycle. For some low-integration detection devices, their sealing structure is usually simple, relying solely on physical pressing or bonding. After prolonged reaction or repeated use, sealing defects may occur. Such sealing defects allow the reaction to be affected by external air, moisture, or contaminants, leading to decreased reaction efficiency and false positive or false negative results, severely impacting detection accuracy. Once the sealing components are damaged, the entire detection device becomes unusable, resulting in resource waste. Developing a sealed reaction card for visual detection of dragon fruit virus that can autonomously and precisely control the reaction temperature, provide a highly reliable sealing environment, and is easy to maintain has become a pressing technical challenge.

[0004] Therefore, this invention proposes a sealed reaction card for visual detection of dragon fruit virus to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems existing in the sealed reaction card for visual detection of dragon fruit virus, such as strong dependence on external temperature control equipment, cumbersome operation process, simple sealing structure, low reliability, and susceptibility to external environmental interference affecting the accuracy of detection results, this utility model aims to provide a sealed reaction card for visual detection of dragon fruit virus with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a sealed reaction card for visual detection of dragon fruit virus, including: a detection box, an inspection cover that is detachably fitted to the top opening of the detection box, a temperature regulation mechanism disposed inside the detection box, and a sealing mechanism disposed at the joint between the detection box and the inspection cover.

[0007] The temperature control mechanism integrates multiple cooperating components. A layer of silicone insulation board is fixedly laid on the inner bottom wall of the detection box, and the heating wire is fixedly installed on the top of the silicone insulation board. Inside the detection box, the dispensing plate horizontally divides its interior into upper and lower spaces. The honeycomb flow equalization plate is fixedly connected to the bottom surface of the dispensing plate and is located above the heating wire. The heat insulation plate is designed to slide between the heating wire and the honeycomb flow equalization plate.

[0008] Furthermore, the sealing mechanism achieves sealing through a sophisticated structural fit. A fixing groove is opened on the top of the test box, and a fixing ring extends downward from the bottom of the inspection cover. The rubber sealing ring is fitted on the outer wall of the fixing ring. When the inspection cover is closed, the fixing ring slides into the fixing groove, and the rubber sealing ring and the inner wall of the fixing groove are squeezed to form a tight filling seal.

[0009] Preferably, in order to ensure that the sliding process of the heat insulation plate is smooth and accurate, guide grooves are provided on the front and rear inner walls of the detection box. Correspondingly, guide blocks are fixedly connected on the front and rear sides of the heat insulation plate. The guide blocks slide in the guide grooves, and the two together constitute the guide assembly, providing stable structural support for the reciprocating motion of the heat insulation plate.

[0010] Furthermore, to facilitate manual operation of the heat insulation board, sliders are fixedly connected to the front and rear sides of the heat insulation board. The sliders are used to manually push the heat insulation board to slide along the guide assembly, thereby achieving flexible control of heat transfer.

[0011] Preferably, in order to achieve real-time monitoring of the reaction temperature, a fixed baffle is fixedly connected to the inner wall of the detection box below the dispensing plate, and the temperature detector is installed on one side of the fixed baffle, which can accurately sense the temperature changes of the reaction environment.

[0012] Preferably, in order to present the monitored temperature data intuitively to the operator, a temperature display screen is fixedly installed on the outer wall of the detection box. The temperature display screen is electrically connected to the temperature detector, providing data support for precise control.

[0013] Preferably, in order to further improve the sealing performance of the device and form a second layer of sealing protection, a mounting groove is provided on the outer wall of the detection box and near its top opening. An expansion compensation sealing ring is installed in the mounting groove. The sealing ring can expand under specific conditions to compensate for possible small gaps.

[0014] Preferably, in order to provide external physical protection and form a third seal, the sealing reaction card also includes an elastic bushing that wraps around the outer area where the test box and the inspection cover connect, further enhancing the reliability of the overall seal and its ability to isolate it from the external environment.

[0015] Preferably, in order to clearly define the reaction area, the area above the dispensing plate is used to place the reaction card. This area can directly bear the reactants and receive uniform heat from the temperature regulation mechanism below, providing an ideal physical platform for detecting the smooth progress of the reaction.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problems of existing technologies where virus detection relies on external temperature control equipment, is cumbersome to operate, and takes a long time by setting a temperature regulation mechanism consisting of a heating wire, a honeycomb flow equalization plate, a sliding heat insulation plate, and a temperature detection and display system inside the detection box. It achieves precise control and autonomous adjustment of the reaction temperature, reduces the use of external equipment, and saves operation time.

[0018] 2. This utility model combines the compression fit of the fixing ring and the rubber sealing ring, the expansion compensation sealing ring's expansion upon contact with water, and the external wrapping of the elastic bushing to form a multi-seal structure. This solves the problems of single sealing performance, insufficient reliability, susceptibility to external environmental interference, or sealing failure due to component aging in the existing reaction device. It effectively prevents the entry of external air, avoids sample contamination and reactant leakage, and significantly improves the sealing performance of the device and the accuracy of the test results.

[0019] 3. This utility model solves the problem of resource waste caused by the difficulty in repairing damaged sealing components in the prior art by designing a quick-replaceable sealing component, thereby increasing the utilization rate of the device and effectively reducing maintenance costs and resource consumption.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0027] Please refer to Figures 1 to 4 This utility model provides a sealed reaction card for visual detection of dragon fruit virus, which aims to solve the problems of low integration of temperature control structure and sealing structure, single function and insufficient reliability of existing virus detection reaction devices.

[0028] like Figure 1 and Figure 2As shown, a sealed reaction card for visual detection of dragon fruit virus includes a detection box 1 and an inspection cover 3 that detachably covers the top opening of the detection box 1. The detection box 1 serves as the main mounting body and reaction container of the entire device, while the inspection cover 3 is used to seal the detection box 1 and facilitate observation of the internal reaction results. A temperature regulating mechanism 2 is provided inside the detection box 1, and a sealing mechanism 4 is provided at the connection between the detection box 1 and the inspection cover 3. The temperature regulating mechanism 2 is used to provide and maintain a constant temperature environment for the detection reaction, while the sealing mechanism 4 is used to ensure the airtightness of the reaction environment and prevent interference from the external environment. The components of the temperature regulating mechanism 2 are located inside the detection box 1. A dispensing plate 201 horizontally divides the interior of the detection box 1 into upper and lower spaces. The upper space of the dispensing plate 201 is used to place the reaction card paper, and the space below the dispensing plate 201 is used for... A silicone insulation board 203 is fixedly laid on the inner bottom wall of the test box 1. The heating wire 204 is fixedly installed on the top of the silicone insulation board 203 to provide a heat source for the reaction. To ensure uniform heat, the honeycomb flow equalization plate 202 is fixedly connected to the bottom surface of the dispensing plate 201 and located above the heating wire 204. The heat insulation plate 208 is slidably disposed between the heating wire 204 and the honeycomb flow equalization plate 202 to block heat transfer when needed. The sealing mechanism 4 achieves high sealing through multiple structures. A fixing groove 402 is opened around the top of the test box 1. A fixing ring 401 extends downward from the bottom of the inspection cover 3. A rubber sealing ring 403 is fitted on the outer wall of the fixing ring 401. When the inspection cover 3 is closed, the fixing ring 401 slides into the fixing groove 402 and the rubber sealing ring 403 fills and seals the fixing groove 402 by compression.

[0029] The sealed reaction card for visual detection of dragon fruit virus also includes a guide component 210. The guide component 210 forms a specific structural fit and connection with the aforementioned detection box 1 and heat insulation plate 208. The guide component 210 provides precise guidance and limit when the heat insulation plate 208 slides to prevent it from shifting, thereby ensuring that the heat insulation plate 208 can accurately block the heat of the heating wire 204.

[0030] Please refer to Figure 2 and Figure 3The guide assembly 210 includes a guide block 2101 and a guide groove 2102. The guide groove 2102 is formed on the front and rear inner walls of the detection box 1. The guide block 2101 is fixedly connected to the front and rear sides of the heat insulation plate 208. In the assembled state, the guide block 2101 is slidably engaged in the guide groove 2102. The sliding engagement structure ensures high stability and anti-deflection capability of the heat insulation plate 208 in the horizontal direction, enabling the heat insulation plate 208 to be accurately positioned to effectively regulate heat transfer. A fixing baffle 205 is fixedly connected to the inner wall of the detection box 1 below the dispensing plate 201. A temperature detector 206 is installed on the fixing baffle 205. The device is used to monitor the temperature of the lower space inside the detection box 1 in real time. A temperature display screen 207 is fixedly installed on the outer wall of the detection box 1. The temperature display screen 207 is electrically connected to the temperature detector 206 and displays the real-time temperature data to the operator, so that the operator can keep track of the temperature inside the device at any time. Slider 209 is also fixedly connected to the front and rear sides of the heat insulation plate 208. The slider 209 is used to manually push the heat insulation plate 208 to slide along the guide component 210, so as to flexibly adjust the position of the heat insulation plate 208 according to the feedback of the temperature detector 206, so as to achieve precise control of the heat emitted by the heating wire 204.

[0031] As a preferred embodiment, to further enhance the sealing performance of the device, please refer to... Figure 1 and Figure 2 A mounting groove 404 is formed on the outer wall of the detection box 1 near its top opening, and an expansion compensation sealing ring 405 is installed in the mounting groove 404. The expansion compensation sealing ring 405 can expand when it encounters moisture, thereby filling the tiny gap that may exist between the detection box 1 and the inspection cover 3, forming a second sealing structure, which complements the internal seal of the rubber sealing ring 403, greatly improving the airtightness of the device in a humid environment.

[0032] As another preferred embodiment, to provide more comprehensive external protection and sealing, please refer to... Figure 1 An elastic bushing 406 is also wrapped around the outer area where the test box 1 connects to the inspection cover 3. As a third physical seal, the elastic bushing 406 can not only prevent external dust and other impurities from entering the connection gap, but also work with the internal rubber sealing ring 403 and expansion compensation sealing ring 405 to achieve a high degree of isolation of the reaction environment and ensure the accuracy and reliability of the test results.

[0033] In another preferred embodiment, in order to define the reaction area of ​​the device, the space above the dispensing plate 201 is used to place the reaction card paper. The area directly carries the reaction carrier containing the sample to be tested, and receives uniform heat from the temperature adjustment mechanism 2 below through the dispensing plate 201, thereby providing a stable and independent physical platform for visually detecting the occurrence of the reaction.

[0034] Working Principle: When testing a solution made from dragon fruit using the sealed reaction card for visual detection of dragon fruit virus, the detection requires a suitable temperature. To ensure a consistent detection temperature, the detection box 1 is divided into two parts by a dispensing plate 201. A honeycomb flow equalization plate 202 is fixed below the dispensing plate 201 to ensure even heat distribution and maintain a uniform temperature across the reaction card paper above the dispensing plate 201. A silicone insulation plate 203 is fixedly installed at the bottom of the space below the detection box 1, and multiple heating wires 204 are fixedly installed on top of the silicone insulation plate 203. This allows the heating wires 204 to be activated when the ambient temperature is low, while the silicone insulation plate 203 prevents the heat from the heating wires 204 from being transferred to the body of the detection box 1. Fixed baffles 205 are fixedly installed on the left and right sides of the space below the detection box 1, and a temperature detector 206 is installed on one side of each fixed baffle 205. A temperature display screen 207 is fixedly installed on the right side, allowing the operator to observe the temperature of various locations in the space below the detection box 1 in real time. At the same time, when the heating wire 204 emits excessive heat, the sliders 209 installed on the front and rear sides of the heat insulation plate 208 slide to the left, causing the heat insulation plate 208 to slide to the left on the inner wall of the detection box 1. This allows the heat insulation plate 208 and the silicone insulation plate 203 to work together to insulate the heat from the heating wire 204. When the heat insulation plate 208 moves, the guide blocks 2101 installed on the front and rear sides of the heat insulation plate 208 slide within the guide grooves 2102 opened on the front and rear sides of the detection box 1, guiding the movement of the heat insulation plate 208. The two components of the guide assembly 210 work together to prevent the movement from deviating. Thus, the device can accurately adjust the appropriate temperature required for the detection reaction through the cooperation of the components of the temperature adjustment mechanism 2, reducing the use of external temperature control equipment and saving operation time.

[0035] Furthermore, when sealing the reaction card, the detection box 1 is aligned with the inspection cover 3. The fixing ring 401, fixed to the bottom of the inspection cover 3, is slid into the fixing groove 402 on the top of the detection box 1. A rubber sealing ring 403 is installed on the outer wall of the fixing ring 401. The detection box 1 and the inspection cover 3 are pressed together, causing the fixing ring 401 and the rubber sealing ring 403 to fill the fixing groove 402, preventing outside air from entering. Simultaneously, a placement groove 404 is opened on the outer wall of the detection box 1, and an expansion compensation seal is installed within the placement groove 404. The sealing ring 405 allows the expansion compensation sealing ring 405 to expand when exposed to water. Finally, an elastic bushing 406 wraps around the area outside the connection between the detection box 1 and the inspection cover 3. Together with the expanding expansion compensation sealing ring 405, it prevents the entry of outside air. This allows the device to achieve a seal through the cooperation of the various components of the sealing mechanism 4 and through a multi-layer sealing structure. Furthermore, it allows for quick replacement of each component when the device is reused, increasing the utilization rate of the device, avoiding resource waste caused by damage to the sealing components, and improving the sealing performance of the device.
