Description

Technical Field

[0001] This utility model relates to the field of sample storage technology, and in particular to a sample extract storage bottle for dragon fruit virus detection. Background Technology

[0002] The detection of dragon fruit viruses is a key link in ensuring the healthy development of the dragon fruit industry. During the detection process, it is usually necessary to properly store the extracted virus sample solution to ensure the activity of the sample and the accuracy of the test results. Sample storage bottles are an indispensable basic tool in the detection process.

[0003] Sample storage bottles widely used in laboratories mostly employ a threaded cap and threaded neck sealing method to ensure that the samples inside are not contaminated or leaked. This structure provides a reliable sealing effect by rotating and tightening, and the performance of the threaded connection is sufficient in normal low-frequency use scenarios.

[0004] In the actual workflow of virus testing, laboratory personnel often need to take multiple samples, add reagents, or conduct parallel experiments on the same sample. However, the storage bottle needs to be opened and closed frequently. For traditional screw caps, each opening and closing requires several turns of rotation to tighten or loosen.

[0005] When this repetitive wrist rotation is repeated hundreds or thousands of times a day, it can cause fatigue in the wrists of the experimenters. Over time, it can even lead to occupational injuries such as carpal tunnel syndrome. The inconvenience and health risks caused by the design of the device constitute a significant shortcoming of the existing technology in specific application scenarios.

[0006] Therefore, this invention proposes a sample extract storage bottle for dragon fruit virus detection to address the shortcomings of existing technologies. Utility Model Content

[0007] In view of the existing technology, the sample extraction liquid storage bottle for dragon fruit virus detection uses a threaded cap. In usage scenarios that require frequent opening and closing, the repetitive rotating action is not only cumbersome to operate, but also causes wrist fatigue and even strain problems for the user. The present invention aims to provide a sample extraction liquid storage bottle for dragon fruit virus detection with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a sample extract storage bottle for dragon fruit virus detection, including an outer shell, an inner shell coaxially disposed within the outer shell, and a bottle cap detachably and sealingly connected to the bottle mouth of the outer shell. The storage bottle also includes an innovative connecting mechanism.

[0009] The connecting mechanism, as the core for achieving rapid opening and closing, consists of a ring-shaped silicone stopper fixedly connected to the outer wall of the bottle cap, multiple metal balls installed on the top of the outer and inner walls, and an L-shaped elastic buckle fixedly connected to the bottom of the bottle cap.

[0010] Furthermore, the outer shell, bottle cap, and connecting mechanism are combined through the following structural relationship: the top of the outer shell is provided with a sealing groove that can form a compression fit with the annular silicone stopper; the outer wall of the bottle cap is provided with a slot that can engage with a metal ball; and the outer wall of the bottle mouth of the outer shell is also provided with a positioning groove that can engage with an L-shaped elastic buckle. Through this multi-point, non-threaded engagement method, the vertical press-locking of the bottle cap is achieved.

[0011] Preferably, the storage bottle also includes a heat preservation mechanism. The cap portion of the heat preservation mechanism includes a heat insulation groove at the top of the cap, a circular heat insulation plate installed in the heat insulation groove, and two placement grooves on the outer wall of the cap. These structures work together to block heat from entering through the cap, thus providing effective thermal protection for the weak points at the bottle opening.

[0012] Preferably, as a further limitation on the bottle cap insulation structure, a heat-insulating sponge ring and a sealing ring are installed sequentially from top to bottom in the placement groove. The heat-insulating sponge ring uses its internal porous structure and air layer to form a heat buffer, while the sealing ring is used to physically block the convection between the external air and the gas inside the bottle. The combination of the two forms a double thermal protection for the gap at the bottle mouth.

[0013] Preferably, in order to achieve the ultimate heat preservation of the bottle body, a vacuum sealed cavity is formed between the outer shell and the inner shell. This vacuum sandwich structure can isolate heat conduction and convection to the maximum extent, which is the basis for achieving long-term heat preservation and maintaining the low temperature environment of the sample.

[0014] Preferably, based on the aforementioned vacuum interlayer, the insulation mechanism also includes a reflective metal plate fixedly connected to the outer wall of the inner shell. This reflective metal plate is mainly used to reflect heat radiation from the external environment and to suppress the heat radiation from the inner liner itself, thereby further improving the overall heat preservation or cold preservation performance and reducing heat exchange.

[0015] Preferably, in order to improve the comfort and safety of use, the insulation mechanism may also include hand slots opened at both ends of the outer wall of the outer shell, and foam boards are filled and fixed in the hand slots. The foam boards not only provide better grip friction and effectively prevent slippage caused by condensation on the bottle, but also serve as a heat insulation material, avoiding the influence of hand temperature on the bottle.

[0016] Preferably, the locking details of the connecting mechanism are optimized, with the metal ball fixed to the top of the inner wall of the outer shell and the inner shell. This arrangement allows the metal ball to accurately spring into the slot on the outer wall of the bottle cap when the bottle cap is pressed vertically down to the predetermined position, achieving a crisp and reliable internal lock and providing the first axial limit for the bottle cap.

[0017] Preferably, in order to make the external locking more stable and balanced, there are three L-shaped elastic buckles. The three L-shaped elastic buckles are evenly fixed to the bottom center of the bottle cap in a circular array. They are engaged one-to-one with the positioning grooves on the outer wall of the bottle mouth, ensuring that the bottle cap will not rotate or shake after locking, and providing a second circumferential and axial limit for the bottle cap.

[0018] This utility model has the following beneficial effects: 1. This utility model solves the problem of poor heat preservation performance and inability to effectively maintain the low temperature environment of samples in existing sample storage bottles by forming a vacuum interlayer between the outer shell and the inner shell, cooperating with the reflective metal plate on the outer wall of the inner shell, and setting multiple heat insulation structures such as heat insulation plate, heat insulation sponge ring and sealing ring on the bottle cap. It achieves a comprehensive three-dimensional heat preservation effect on the bottle body and bottle mouth, ensuring sample activity and extending its effective storage time.

[0019] 2. This utility model solves the problem of cumbersome operation and easy wrist injury caused by the use of threaded caps on existing storage bottles by setting up a press-type multi-point locking mechanism consisting of an annular silicone stopper, a metal ball, and an L-shaped elastic buckle. It achieves the technical effect of quick opening and closing and reliable sealing, greatly improving the convenience of operation and ergonomics.

[0020] 3. This utility model solves the problem of traditional thermos bottles being difficult to hold due to their smooth surface or condensation caused by temperature differences by setting a hand groove with an internal foam board on the outer wall of the outer shell. It achieves the technical effects of anti-slip, heat insulation, and stable grip, and improves the safety during operation. Attached Figure Description

[0023] 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

[0024] Please refer to Figures 1 to 4 This utility model provides a sample extract storage bottle for dragon fruit virus detection, which aims to solve the problems of insufficient heat preservation performance of existing sample storage bottles leading to sample inactivation, and repeated twisting of the screw cap 3 causing wrist injury to the experimenter.

[0025] like Figure 1 and Figure 3 As shown, a sample extract storage bottle for dragon fruit virus detection includes an outer shell 1 and an inner shell 2 coaxially disposed inside the outer shell 1. A vacuum sealing cavity is formed between the outer shell 1 and the inner shell 2. The storage bottle also includes a bottle cap 3 that is detachably sealed to the bottle mouth of the outer shell 1. The entire device works in concert through a connecting mechanism 5 and a heat preservation mechanism 4.

[0026] like Figure 2 and Figure 4As shown, the connecting mechanism 5 is used to quickly lock and unlock the bottle cap 3 and the bottle body. The connecting mechanism 5 includes an annular silicone plug 501 fixedly connected to the outer wall of the bottle cap 3, and multiple metal balls 503 installed on the top of the inner wall of the outer shell 1 and the inner shell 2. The metal balls 503 are fixed to the top of the inner wall of the outer shell 1 and the inner shell 2, and are used to snap into the corresponding slots 504 when the bottle cap 3 is installed in place. The connecting mechanism 5 also includes three L-shaped elastic buckles 505 fixedly connected to the bottom of the bottle cap 3. The L-shaped elastic buckles 505 are evenly fixed in the middle of the bottom of the bottle cap 3. A sealing groove 502 is provided at the top of the outer shell 1. The sealing groove 502 is pressed and fitted with the annular silicone plug 501. A slot 504 is provided on the outer wall of the bottle cap 3 to engage with the metal balls 503. A positioning groove 506 is provided on the outer wall of the bottle mouth of the outer shell 1 to engage with the L-shaped elastic buckles 505, and is used to achieve snap-fit ​​fixation when the bottle cap 3 is installed.

[0027] A sample extract storage bottle for dragon fruit virus detection also includes a heat preservation mechanism 4, and the heat preservation mechanism 4 forms a specific structural fit and connection relationship with the aforementioned outer shell 1, inner shell 2 and bottle cap 3.

[0028] Please refer to Figure 1 , Figure 3 and Figure 4 The bottle body of the insulation mechanism 4 includes a reflective metal plate 401 fixedly connected to the outer wall of the inner shell 2, and a hand slot 402 opened at both ends of the outer wall of the outer shell 1. A foam board 403 is fixedly connected in the hand slot 402. The bottle cap 3 of the heat preservation mechanism 4 includes a heat insulation groove 407 opened at the top of the bottle cap 3 and a circular heat insulation plate 408 installed in the heat insulation groove 407. The heat preservation mechanism 4 also includes two placement grooves 404 opened on the outer wall of the bottle cap 3. In the specific assembled state, heat-insulating sponge ring 405 and sealing ring 406 are installed sequentially from top to bottom in the mounting groove 404. The heat-insulating sponge ring 405 is used to form an air buffer layer, and the sealing ring 406 is used to block air convection. This multi-layer barrier structure formed on the side wall of the bottle cap 3, together with the circular heat-insulating plate 408 installed on the top, constitutes a three-dimensional heat preservation for the bottle mouth area, ensuring that the heat seeping in from the gap of the bottle cap 3 is effectively slowed down. At the same time, the vacuum sealing cavity formed between the outer shell 1 and the inner shell 2, together with the reflective metal plate 401 on the outer wall of the inner shell 2, ensures that heat conduction, heat convection and heat radiation of the bottle body are effectively blocked.

[0029] As a preferred embodiment, in order to enhance the sealing and heat preservation effect of the bottle cap 3, there can be two placement grooves 404 on the outer wall of the bottle cap 3, and the two placement grooves 404 are arranged vertically and horizontally. The upper placement groove 404 is equipped with a heat insulation sponge ring 405, and the lower placement groove 404 is equipped with a sealing ring 406. By combining physical barrier with air layer buffer, the sealing and heat preservation performance at the bottle mouth is further improved.

[0030] As another preferred embodiment, in order to improve the stability and reliability of the connecting mechanism 5, the number of metal balls 503 installed on the top of the inner wall of the outer shell 1 and the inner shell 2 can be multiple, and they are evenly distributed along the circumferential direction of the inner wall of the bottle mouth, so that after the bottle cap 3 is pressed in, it can be evenly inserted into the slot 504 from multiple directions, making the bottle cap 3 more secure and less prone to shaking.

[0031] As another preferred embodiment, in order to ensure that the L-shaped elastic buckle 505 and the positioning groove 506 are accurately and firmly engaged, three L-shaped elastic buckles 505 are fixed at the bottom center of the bottle cap 3, and the three L-shaped elastic buckles 505 are evenly distributed at 120 degrees with the central axis of the bottle cap 3 as the center. Correspondingly, three positioning grooves 506 are also opened on the outer wall of the bottle mouth of the outer shell 1. This evenly distributed structure makes the force more balanced when locking.

[0032] Working principle: In the production of sample extraction liquid storage bottles for dragon fruit virus detection, the traditional single-layer bottle body is upgraded to a structure where the outer shell 1 and the inner shell 2 are connected. Both the outer shell 1 and the inner shell 2 are made of high-strength transparent material, allowing direct observation of the liquid state inside the bottle. A sealed cavity is created between the outer shell 1 and the inner shell 2. This sealed cavity is evacuated to a vacuum state to prevent heat transfer. Then, a reflective metal plate 401 is fixed to the outer wall of the inner shell 2 between the two shells to reduce its own heat radiation. Handhold slots 402 are opened on both the left and right ends of the outer wall of the outer shell 1, and foam boards 403 are installed in the handhold slots 402. Since a bottle cap 3 is fixed to the top of the inner wall of the storage bottle, a bottle cap 3 is located on the lower part of the outer wall of the bottle cap 3. Two placement slots 404 are provided. A sealing ring 406 is installed in the lower placement slot 404 to form the first seal and block air convection. A heat-insulating sponge ring 405 is installed in the upper placement slot 404 to form an air buffer layer and further slow down the heat seepage from the bottle mouth gap. Finally, a heat insulation slot 407 is provided at the top of the bottle cap 3, and a circular heat insulation plate 408 is installed in the heat insulation slot 407 to prevent heat from being directly transferred from the top of the bottle cap 3 to the bottle. This allows the device to complete the heat preservation treatment of the sample extract through the cooperation of the various components of the heat preservation mechanism 4, from the bottle body and bottle mouth, to avoid the temperature inside the bottle changing with the ambient temperature, thus ensuring the freshness and integrity of the sample and extending the sample preservation time. Furthermore, when installing and opening the bottle cap 3, an annular silicone plug 501 is installed in the middle of the outer wall of the bottle cap 3, and a sealing groove 502 is opened at the top of the outer shell 1. When the bottle cap 3 is pressed and locked, the annular silicone plug 501 will be squeezed and thus fit into the sealing groove 502. When the bottle cap 3 is slid into the storage bottle, multiple metal beads 503 fixed to the top of the inner wall of the outer shell 1 and the inner shell 2 are first squeezed, and when the bottle cap 3 is installed in place, the metal beads 503 can be inserted into the slot 504 opened on the outer wall of the bottle cap 3. Finally, three L-shaped elastic buckles 505 are evenly fixed in the middle of the bottom of the bottle cap 3. When the bottle cap 3 is installed, it can be positioned in the positioning groove 506 opened at the bottle mouth position on the outer wall of the outer shell 1. This allows the device to fix the bottle cap 3 through multiple connections by cooperating with the various parts of the connecting mechanism 5, avoiding the wrist injury caused by repeated unscrewing actions for experimental personnel who need to perform frequent testing operations when using threaded connections.
