[0002] Raman test strips are rapid detection tools based on Raman spectroscopy technology, widely used in various fields including biomedicine, environmental analysis, food safety, and public safety. These kits utilize surface-enhanced Raman scattering (SERS) technology, using specific nanomaterials to amplify the Raman signal, thereby achieving highly sensitive detection of target molecules.

[0003] Most reagent kits sold on the market currently have open dispensing ports. Before formal testing, external liquids can easily enter the reagent kit through the dispensing port. Liquids trapped inside the reagent kit can easily mix with the sample to be tested during formal testing, causing the sample to be diluted and resulting in errors in the reagent kit's testing. Utility Model Content

[0004] The purpose of this invention is to provide a Raman test paper kit with a self-sealing structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A Raman test strip kit with a self-sealing structure includes a box structure, which is composed of a first shell and a second shell that are detachably connected and sealed together. The first shell is provided with a drop outlet, and a sealing ring is provided along the axial direction of the drop outlet. The sealing ring can be inserted into and abut against a sealing block that is slidably provided on the first shell.

[0007] It also includes an unlocking mechanism disposed on the first housing, which can sequentially control the sealing ring to move downward along the axial direction of the drip outlet and release the sealing ring from the unlocked state of the drip outlet.

[0008] The Raman test strip kit with a self-sealing structure as described above: the unlocking mechanism includes an unlocking rod threadedly connected to the first housing, and one end of the unlocking rod inserted into the first housing is rotatably connected to a connecting plate slidably disposed in the first housing;

[0009] It also includes an intermittent control component disposed on the connecting plate.

[0010] The Raman test strip kit with a self-sealing structure as described above: the intermittent control component includes at least one set of push rods fixedly installed on the connecting plate, the push rods being slidably connected to the first housing, and a first sleeve and a second sleeve being respectively provided along the axial direction of the push rods and rotatably connected to the inner wall of the first housing.

[0011] The Raman test strip kit with a self-sealing structure as described above: a first ball and a second ball are movably disposed on the push rod, and a first limiting groove and a second limiting groove adapted to the first ball and the second ball are formed on the first sleeve and the second sleeve.

[0012] As described above, in the Raman test strip kit with a self-sealing structure: the downward movement of the sealing ring is controlled by a first threaded pusher disposed within the first housing, and the first threaded pusher is connected to the first sleeve.

[0013] The Raman test paper kit with a self-sealing structure as described above: an embedded cavity is formed on the first shell, a second threaded pusher is provided in the embedded cavity, and the second threaded pusher is connected to the second sleeve through a transmission member.

[0014] The Raman test strip kit with a self-sealing structure as described above: the first threaded pusher includes a first lead screw rotatably disposed inside the first housing, the first lead screw being rotatably connected to the first sleeve through a first bevel gear set, and a connecting hoop threadedly connected to the first lead screw and fixed to the sealing ring.

[0015] The Raman test strip kit with a self-sealing structure as described above: the second threaded pusher includes a second lead screw rotatably disposed in the inner cavity, and a threaded sleeve is threadedly connected to the second lead screw. The threaded sleeve can pass through the groove formed by the first housing and be fixed to the sealing block.

[0016] The Raman test strip kit with a self-sealing structure as described above: the transmission component includes a first transmission shaft rotatably disposed within the first housing, one end of the first transmission shaft being rotatably connected to the second lead screw via a second bevel gear set, and the other end being rotatably connected to the second transmission shaft rotatably disposed within the first housing via a third bevel gear set, and the second transmission shaft being connected to the second sleeve via a belt.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] During testing, the manual unlocking mechanism sequentially operates the sealing block and the sealing ring, causing the sealing ring to move downwards along the axis of the droplet opening and retract into the opening. At this point, the sealing ring and the sealing block are not in contact. The unlocking mechanism continues to operate without affecting the movement of the sealing ring, moving the sealing block along the length of the first housing to release the seal on the droplet opening. The design of the sealing block and sealing ring effectively prevents the possibility of water leakage within the reagent kit. Furthermore, during the process of releasing the seal on the droplet opening, the movement of the sealing block prevents wear on the sealing ring, ensuring the sealing effect of the sealing ring and effectively preventing external liquids from entering the kit structure when not in use, further improving the accuracy of the reagent kit's testing.

[0028] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0029] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0030] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0031] Please see Figures 1-8 In this embodiment of the present invention, a Raman test strip kit with a self-sealing structure includes a box structure. The box structure is composed of a first shell 1 and a second shell 2 that are detachably connected and sealed together. The first shell 1 is provided with a drop outlet 102, and a sealing ring 4 is provided along the axial direction of the drop outlet 102. The sealing ring 4 can be inserted into and abut against a sealing block 3 that is slidably provided on the first shell 1.

[0032] It also includes an unlocking mechanism disposed on the first housing 1, which can sequentially control the sealing ring 4 to move downward along the axial direction of the drip outlet 102 and release the sealing ring 4 from the unlocked state of the drip outlet 102.

[0033] In detail, during the test, the manual unlocking mechanism operates the sealing block 3 and the sealing ring 4 sequentially. This causes the sealing ring 4 to move downwards along the axis of the drip port 102 and retract into the drip port 102. At this time, the sealing ring 4 and the sealing block 3 are not in contact. The unlocking mechanism continues to operate without affecting the movement of the sealing ring 4, driving the sealing block 3 to move along the length of the first housing 1, thus releasing the sealing of the drip port 102. The design of the sealing block 3 and the sealing ring 4 effectively avoids the possibility of water leakage inside the test kit. Furthermore, during the process of releasing the sealing of the drip port 102, the movement of the sealing block 3 is prevented from causing wear to the sealing ring 4, ensuring the sealing effect of the sealing ring 4. This effectively prevents external liquids from entering the box structure when the test kit is not in use, further improving the accuracy of the test.

[0034] For further solutions to this utility model, please refer to [link / reference]. Figure 2 and Figure 5 The unlocking mechanism includes an unlocking rod 6 that is threadedly connected to the first housing 1, and one end of the unlocking rod 6 that is inserted into the first housing 1 is rotatably connected to a connecting plate 7 that is slidably disposed in the first housing 1.

[0035] It also includes an intermittent control component disposed on the connecting plate 7.

[0036] The intermittent control component includes at least one set of push rods 8 fixedly installed on the connecting plate 7. The push rods 8 are slidably connected to the first housing 1. A first sleeve 10 and a second sleeve 11 are respectively provided along the axial direction of the push rods 8 and are rotatably connected to the inner wall of the first housing 1.

[0037] The push rod 8 is movably provided with a first ball bearing 801 and a second ball bearing 802, and the first sleeve 10 and the second sleeve 11 are provided with a first limiting groove 1001 and a second limiting groove 1101 that are adapted to the first ball bearing 801 and the second ball bearing 802.

[0038] Preferably, the first limiting groove 1001 is divided into an A threaded groove and an A straight groove, and the second limiting groove 1101 is divided into a B straight groove and a B threaded groove.

[0039] In the initial state, the first ball 801 is located in the A threaded groove and the second ball 802 is located in the B straight groove. When the unlocking rod 6 is manually driven to rotate, the unlocking rod 6 rotates relative to the first housing 1 and moves toward one end of the first housing 1. At this time, the rotation of the unlocking rod 6 does not affect the connecting plate 7. However, when the unlocking rod 6 moves in a straight line along the axial direction of the unlocking rod 6, it drives the connecting plate 7 to move synchronously, so as to meet the requirements of driving the intermittent control component.

[0040] Specifically, when push rod 8 moves, it drives the first ball 801 and the second ball 802 to move synchronously. At this time, the first ball 801 exerts an inclined force on the first sleeve 10, causing the first sleeve 10 to rotate. The movement of the second ball 802 does not affect the second sleeve 11. When the first ball 801 moves to the straight groove A, the second ball 802 moves to the threaded groove B. At this time, the movement of the first ball 801 does not affect the first sleeve 10, but the second ball 802 exerts an inclined force on the second sleeve 11, causing the second sleeve 11 to rotate, so as to achieve the requirement that the first sleeve 10 and the second sleeve 11 rotate sequentially.

[0041] Preferably, the push rod 8 is provided with at least one set of strip blocks, and multiple limiting plates 9 are fixedly installed inside the first housing 1. The limiting plates 9 are formed with through holes for the push rod 8 to pass through, and the through holes are provided with strip grooves that slide with the strip blocks to realize the sliding connection between the push rod 8 and the inside of the first housing 1.

[0042] For further solutions to this utility model, please refer to [link / reference]. Figure 5 and Figure 6 The downward movement of the sealing ring 4 is controlled by a first threaded pusher disposed in the first housing 1, and the first threaded pusher is connected to the first sleeve 10.

[0043] An inner cavity 103 is formed on the first housing 1, and a second threaded pusher is provided in the inner cavity 103. The second threaded pusher is connected to the second sleeve 11 through a transmission member.

[0044] The first threaded pusher includes a first lead screw 13 rotatably disposed inside the first housing 1. The first lead screw 13 is rotatably connected to the first sleeve 10 through a first bevel gear set 12, and a connecting hoop 5 fixed to the sealing ring 4 is threadedly connected to the first lead screw 13.

[0045] The second threaded pusher includes a second lead screw 14 rotatably disposed in the inner cavity 103, and a threaded sleeve 15 is threadedly connected to the second lead screw 14. The threaded sleeve 15 can pass through the sliding groove 101 formed by the first housing 1 and be fixed to the sealing block 3.

[0046] The transmission component includes a first transmission shaft 17 rotatably disposed within the first housing 1. One end of the first transmission shaft 17 is rotatably connected to the second lead screw 14 via a second bevel gear set 16, and the other end is rotatably connected to a second transmission shaft 19 rotatably disposed within the first housing 1 via a third bevel gear set 18. The second transmission shaft 19 is connected to the second sleeve 11 via a belt 20.

[0047] To elaborate, when the first sleeve 10 rotates, it drives the first lead screw 13 to rotate under the transmission of the first bevel gear set 12. When the first lead screw 13 rotates, it drives the connecting hoop 5 to move downward, so that the sealing ring 4 moves downward along the axis of the dripping port 102. This ensures the sealing effect of the dripping port 102 while avoiding interference with the movement of the sealing block 3 caused by the presence of the sealing ring 4.

[0048] When the second sleeve 11 rotates, the sealing ring 3 is retracted into the drip outlet 101. Under the transmission of the belt 20, it can drive the second transmission shaft 19 to rotate. At this time, under the transmission of the third bevel gear set 18, it drives the first transmission shaft 17 to rotate, and under the transmission of the second bevel gear set 16, it drives the second lead screw 14 to rotate. When the second lead screw 14 rotates, it drives the threaded sleeve 15 to move linearly along the axis of the second lead screw 14. At this time, the threaded sleeve 15 slides relative to the first housing 1 in the slide groove 102 and drives the sealing block 3 to move synchronously, so as to release the unlocking state of the sealing block 3 on the drip outlet 102.

[0049] The embedded cavity 103 and the interior of the first shell 1 are two independent chambers, which prevents liquid that accidentally drips into the embedded cavity 103 from entering the first shell 1, thus further ensuring the accuracy of the reagent kit.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
