Detailed Implementation

[0023] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] As mentioned in the background section, this application proposes a reagent card testing device, including a hollow housing with a front panel and a back panel facing each other. A test card slot 101 is provided on the side wall of the housing. The reagent card testing device includes a dustproof glass 12, a dustproof sealing ring 13, and a fixing cover 15. A mounting base 102 is provided on the inner surface of the back panel, and a through hole 104 is provided on the mounting base 102, which communicates with the test card slot 101. A glass mounting groove is provided on the side of the mounting base 102 facing the front panel. The through hole 104, projected along the direction from the front panel to the back panel of the housing, falls into the glass mounting groove, where the dustproof glass 12 is embedded. The dustproof sealing ring 13 is located between the glass mounting groove and the dustproof glass 12. The fixing cover 15 is installed on the side of the mounting base 102 facing the front panel to press the dustproof glass 12 against the side where the test card slot 101 is located.

[0026] In this embodiment, the dustproof glass 12 covers the through hole 104 under the action of the fixed cover plate 15, thereby isolating the cavity inside the housing used to accommodate components from the detection card slot 101. This effectively prevents external dust or rainwater from entering the internal cavity of the housing from the detection card slot 101, protecting the internal components. Furthermore, the dustproof sealing ring 13 seals the gap between the dustproof glass 12 and the glass mounting groove, improving the sealing performance.

[0027] It should be noted that the housing includes a lower housing 1 and an upper housing 2 connected together. Both the upper housing 2 and the lower housing 1 are hollow, and they are connected by threaded fasteners. When the lower housing 1... Figure 5 When the lower housing 1 is placed in the correct position, i.e., when it lies flat on a plane, as can be seen from the figure, the mounting base 102 is located on the inner bottom wall of the lower housing 1. The through hole 104 on the mounting base 102 is located above the detection card slot 101. The fixing cover 15 is located above the dustproof glass 12 and presses down the dustproof glass 12.

[0028] by Figure 4 To further explain from this perspective: the through hole 104 is a rectangular hole, and the projection of the through hole 104 in the vertical direction falls completely inside the dustproof glass 12. That is to say, when the dustproof glass 12 is closed in the glass mounting groove, the dustproof glass 12 completely covers the through hole 104. In addition, the inner wall of the glass mounting groove is provided with an annular sealing ring assembly groove, and the dustproof sealing ring 13 is embedded in the sealing ring assembly groove.

[0029] Furthermore, multiple threaded holes are provided on the top surface of the mounting base 102, the vertical projection of the fixing cover plate 15 is greater than the vertical projection of the dustproof glass 12, and multiple countersunk holes corresponding to the threaded holes are provided around the fixing cover plate 15.

[0030] When assembling the dustproof glass 12, firstly, the dustproof sealing ring 13 is embedded into the sealing ring assembly groove on the inner bottom wall of the glass mounting groove. Next, the fixing cover plate 15 is placed on the top surface of the mounting base 102, and the position of the fixing cover plate 15 is adjusted so that the countersunk hole on the fixing cover plate 15 is aligned with the threaded hole on the mounting base 102. Finally, screws or bolts are installed into the countersunk hole of the fixing cover plate 15 and tightened so that the fixing cover plate 15 tightly presses against the dustproof glass 12 and the dustproof sealing ring 13. In this way, the internal cavity of the housing and the detection card slot 101 can be effectively isolated, and external dust or rainwater is difficult to enter the cavity where the internal components of the housing are located through the detection card slot 101, which greatly improves the dustproof and waterproof effect.

[0031] It should be noted that the internal cavity of the housing houses the detection assembly 10, which includes a base frame, a QR code scanner, a camera, a light source, and a lens group. The camera, light source, lens group, and CMOS sensor are mounted on the base frame, which is installed inside the housing cavity. The light source, camera, lens group, and QR code scanner are all located above the dustproof glass 12. In other words, the light emitted by the light source passes through the dustproof glass 12 and illuminates the reagent card in the detection card slot 101 below. The T and C lines that have already developed on the reagent card reflect the light back. The reflected light passes through the lens group, which collects this reflected light and clearly images it onto the CMOS sensor of the camera to capture a high-definition color image containing information from all channel stripes.

[0032] Considering that the sealing performance of the shielding glass at point 6 on the front of the casing was generally poor and dust easily entered, the following improvements were made in this embodiment:

[0033] like Figure 2 As shown, the reagent card testing device includes a shielding glass 6, a display screen 4, and a shielding glass sealing gasket 7. A screen window 201 is provided on the front panel of the upper housing 2. An annular mounting groove is provided on the side of the front panel of the upper housing 2 facing the lower housing 1. The shielding glass sealing gasket 7 is embedded and fixed in the mounting groove. The shielding glass 6 is fixedly attached to the screen of the display screen 4, and the substrate of the display screen 4 is fixed to the front panel of the upper housing 2 by threaded fasteners, so that the shielding glass 6 is tightly attached to the inner wall of the front panel of the upper housing 2, thereby sealing the screen window 201.

[0034] It should be noted that the shielding glass sealing gasket 7 between the shielding glass 6 and the front panel of the upper housing 2 further improves the sealing effect, ensuring that external dust cannot easily enter the internal cavity of the housing through the gap between the shielding glass 6 and the front panel of the upper housing 2, and the dustproof and waterproof effects are significantly improved.

[0035] In this embodiment, on the back panel of the lower housing 1, that is Figure 4The bottom panel of the lower housing 1 has mounting holes, and a sealing base plate 14 is fixedly installed in the mounting holes with screws. The bottom surface of the sealing base plate 14 is flush with the bottom surface of the lower housing 1, and the mounting holes are connected to the detection card slot 101. Since the detection card slot 101 is long and narrow, it is not convenient to clean the deep interior of the detection card slot 101. However, after setting the sealing base plate 14, the internal space of the detection card slot 101 can be exposed by removing the sealing base plate 14, which greatly facilitates the cleaning of the interior of the detection card slot 101.

[0036] In some embodiments, such as Figure 2 As shown, the shielding glass 6 and the display screen 4 are connected by a conductive adhesive strip 5. The conductive adhesive strip 5 connects the shielding glass 6 and the display screen 4, which not only serves as an adhesive but also shields against electromagnetic interference (EMI), improving the stability of the equipment in complex electromagnetic environments.

[0037] In some embodiments, such as Figure 2 As shown, the reagent card testing device also includes a waterproof button module 8 and a button pressure plate 9. The waterproof button module 8 includes multiple control buttons, and the front panel of the upper housing 2 has multiple button holes that match the control buttons. The control buttons are electrically connected and installed on the button pressure plate 9, which is fixed to the front panel with screws. It should be noted that the control buttons are covered with rubber waterproof sleeves, which also seal the gap between the control buttons and the button holes, improving the sealing effect.

[0038] In this embodiment, as Figure 2 Two mounting holes are provided on the top of the lower housing 1. Electromagnetic rings are installed in the mounting holes. The charging connector 16 and the communication connector 17 are sealed and installed in the two mounting holes and cooperate with the electromagnetic rings. It should be noted that the electromagnetic ring is a metal clamping ring (or lock nut) with internal threads. When the connector is inserted into the mounting hole, the electromagnetic ring is tightened by rotating it, which can generate a strong and uniform axial clamping force. This clamping force acts on the O-ring rubber seal of the connector (usually located in the groove of the connector shell), causing it to elastically deform and tightly fill the gap between the connector shell and the inner wall of the mounting hole of the lower housing 1, forming a reliable radial static sealing barrier, effectively preventing dust and liquid from entering from the interface gap.

[0039] In some embodiments, both the charging connector 16 and the communication connector 17 are fitted with waterproof connector covers 18 to prevent dust or water from entering the charging connector 16 and the communication connector 17.

[0040] In some embodiments, such as Figure 2 and Figure 3As shown, a sealing groove 103 is provided around the periphery of the end face where the lower housing 1 mates with the upper housing 2. Correspondingly, a sealing groove 103 is also provided around the periphery of the end face where the upper housing 2 mates with the lower housing 1. A housing sealing ring 11 is provided within the sealing groove 103 of the upper housing 2 and the lower housing 1. The housing sealing ring 11 can seal the gap between the mating surfaces of the upper housing 2 and the lower housing 1, improving the dustproof and waterproof effect.

[0041] In this embodiment, the reagent card detection device also includes a main control board 3 and a battery (not shown in the figure). The main control board 3 is fixedly installed on the inner wall of the upper housing 2, and the battery is installed inside the lower housing 1.

[0042] In summary, this reagent card testing device has been improved in the following aspects to enhance its dustproof and waterproof performance: First, the dustproof glass 12 physically isolates the test card slot 101 from the internal cavity of the housing, directly blocking the intrusion of dust and liquid. The dustproof sealing ring 13 eliminates the microscopic gaps between the dustproof glass 12 and the glass mounting groove, achieving a leak-free seal. The fixing cover 15 provides uniform and adjustable clamping force through countersunk screws, ensuring long-term stable contact of the dustproof glass 12 and resistance to vibration and impact. In other words, the cooperation of the fixing cover 15, the dustproof glass 12, and the dustproof sealing ring 13 fundamentally cuts off the path for dust and liquid to enter the core electronic area from the most easily intruded test card slot 101, protecting the internal components.

[0043] Secondly, the shielding glass sealing gasket 7 fills the mounting groove on the inner wall of the front panel of the upper housing 2 to form the first flexible sealing barrier. Then, the display substrate is connected to the upper housing 2 using threaded fasteners, so that the shielding glass 6 is tightly attached to the upper housing 2 to form a rigid second seal. This ensures long-term stable dustproof and waterproof performance and prevents dust or water from entering the housing from the screen window 201.

[0044] Furthermore, if the shielding glass 6 is damaged, the glass can be replaced separately with removable screws, eliminating the need to replace the expensive display assembly. The shielding glass sealing gasket 7, as an independent part, is also easy to replace, significantly reducing maintenance costs and complexity. Finally, the shielding glass 6 is connected to the display screen 4 via conductive adhesive strip 5. This not only provides physical adhesion but, more importantly, forms a continuous conductive path, effectively shielding high-frequency electromagnetic interference from the internal circuitry and improving the device's electromagnetic compatibility and display stability.

[0045] Third, the buttons have built-in rubber waterproof sleeves, forming an effective seal between the buttons and the button holes.

[0046] Fourth, the charging connector 16 and the communication connector 17 are sealed and fixed by an electromagnetic ring, while the waterproof cover 18 of the connector provides additional protection when not in use.

[0047] Fifth, a housing sealing ring 11 is provided in the sealing groove 103 of the mating surface of the upper housing 2 and the lower housing 1 to seal the gap between the mating surfaces of the upper housing 2 and the lower housing 1, thereby improving the dustproof and waterproof effect.

[0048] As can be seen, the comprehensive sealing solution formed by combining the above-mentioned methods significantly improves the sealing performance of the reagent card testing device, effectively preventing dust or water from entering.

[0049] Furthermore, in this embodiment, the detection slot 101 is an area prone to contamination, and sample residue or dust accumulation is inevitable after long-term use. The removable sealing base plate 14 allows users or maintenance personnel to thoroughly clean the inside of the detection slot 101, improving the maintainability of the equipment.

[0050] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
