[0038] Urine analysis equipment, especially portable urine analyzers, is favored by users due to its compact size and ease of operation. However, a significant drawback exists in currently available portable urine analyzers: during use, urine and water from cleaning can easily seep into the device, damaging its internal circuitry. This liquid intrusion can not only cause partial or complete malfunction but also force users to perform frequent repairs, resulting in significant inconvenience and additional costs. From a technical perspective, the waterproof design of existing equipment is often inadequate and cannot effectively prevent liquid penetration. Furthermore, from an economic standpoint, frequent repairs and equipment replacements increase the financial burden on users. Moreover, from an efficiency perspective, equipment malfunctions caused by liquid intrusion not only hinder normal use but may also negatively impact the accuracy and timeliness of medical diagnoses.
[0039] Based on the problems existing in the current technology, please refer to Figures 1 to 3 This utility model provides a waterproof portable urine analyzer 10, applied in the field of medical device technology. It achieves IP67 waterproof rating, ensuring that even if the device comes into contact with liquid during use and cleaning, the internal circuitry will not be damaged, thus preventing device malfunction and reducing maintenance frequency.

[0042] In this embodiment, by interfering with the end of the top cover 200 and the mounting housing 100, assembly and disassembly are not only convenient, but the top cover 200 and the mounting housing 100 are also tightly connected. This also avoids the formation of gaps between the top cover 200 and the mounting housing 100, thus effectively preventing dust, liquids, etc. from entering the interior of the mounting housing 100. By covering the outside of the processor 400 with the face cover 300 and providing a seal at the connection between the face cover 300 and the mounting housing 100, a sealed mounting cavity is formed, thereby preventing dust and liquids from contacting the processor 400. This effectively achieves the waterproof function of the waterproof portable urine analyzer 10, thus improving the service life of the waterproof portable urine analyzer 10, thereby improving the reliability of the product and the user experience.
[0043] Further, please refer to Figure 4 and Figure 5 The top cover 200 includes a cover body 210 and a first adhesive 220. The first adhesive 220 is disposed on the cover body 210 and is interference-fitted with the mounting housing 100.
[0044] In this embodiment, the first colloid 220 is press-fitted with the mounting housing 100 to achieve a seal at the connection between the top cover 200 and the mounting housing 100, thereby achieving waterproofing.
[0045] Furthermore, the top cover 200 also includes a second adhesive 230, which is disposed on the cover body 210. The processor 400 is provided with a terminal block 410 and a waterproof ring 420 at one end near the top cover 200. The waterproof ring 420 is sleeved on the terminal block 410, and the second adhesive 230 and the waterproof ring 420 are interference-fitted.
[0046] In this embodiment, a waterproof ring 420 is fitted onto the end of the terminal block 410, and the second adhesive 230 is press-fitted with the waterproof ring 420 to achieve a seal at the connection between the top cover 200 and the processor 400, thereby achieving the purpose of waterproofing.
[0047] Alternatively, terminal 410 can be a TYPE C terminal.
[0048] It should be noted that the first colloid 220 can be a soft colloid, the second colloid 230 can be a hard colloid, and the top cover 200 can be made by a two-stage injection molding process, that is, firstly, the second colloid 230 is injected into the cover body 210, and then the first colloid 220 and the second colloid 230 are injected together to form the top cover 200.
[0049] Further, please refer to Figure 6 and Figure 7 The mounting housing 100 and the face cover 300 are provided with first mounting grooves 110 at both ends of the length direction in which they contact each other.

[0050] In this embodiment, the mounting housing 100 is provided with a first mounting groove 110 at both contact points with the face cover 300 along its length, and the first mounting groove 110 is circumferentially arranged around the housing. Therefore, when the face cover 300 is installed on the mounting housing 100, a sealing element is provided in the first mounting groove 110 to achieve sealing at the two contact points with the face cover 300 along its length, thereby achieving the purpose of waterproofing.
[0051] Furthermore, the mounting housing 100 is provided with second mounting grooves 120 at both ends in the width direction where it contacts the face cover 300. The second mounting grooves 120 extend along the length direction of the mounting housing 100 and are used to install the seal.
[0052] In this embodiment, the mounting housing 100 is provided with a second mounting groove 120 at two contact points in the width direction that contact the face cover 300, and the second mounting groove 120 extends along the length direction of the mounting housing 100. Therefore, when the face cover 300 is installed on the mounting housing 100, a sealing element is provided in the second mounting groove 120 to achieve sealing at the two contact points in the width direction that contact the face cover 300, thereby achieving the purpose of waterproofing.
[0053] It can be understood that the two first mounting grooves 110 correspond to the two wide sides of the face cover 300, and the two second mounting grooves 120 correspond to the two long sides of the face cover 300. Therefore, by setting seals in the two first mounting grooves 110 and the two second mounting grooves 120, the sealing between the entire face cover 300 and the mounting housing 100 can be achieved.
[0054] It should be noted that the sealing element described in this utility model can be polyurethane hot melt adhesive or silicone rubber. Of course, it can also be other types of sealing elements, as long as they can play a sealing role. No specific limitation is made here.
[0055] Further, please refer to Figure 3 , Figure 8 and Figure 9The end of the mounting housing 100 away from the top cover 200 is also provided with a detection module 500, a mounting component 600 and a shell 700. The shell 700 is located outside the mounting component 600, and the detection module 500 is located inside the mounting component 600. The shell 700 is also used to install the test strip 11, and the detection module 500 is used to detect the reaction result of the test strip 11.
[0056] In this embodiment, a flow guide is provided at the top of the housing 700 so that the user can collect the liquid to be tested from the flow guide and allow the liquid to flow into the mounting housing 100 along the flow guide and finally flow to the test strip 11, thereby completing the collection of the liquid to be tested; the detection module 500 detects and analyzes the reaction of the test strip 11 after contacting the liquid, thereby completing the analysis of the liquid to be tested.
[0057] Furthermore, the waterproof portable urine analyzer 10 also includes a light-transmitting element 800, which is disposed on the mounting element 600 and located between the detection module 500 and the test strip 11.
[0058] In this embodiment, the light-transmitting element 800 is provided to ensure that the detection module 500 can successfully detect the color change of the test strip 11. Moreover, the light-transmitting element 800 is provided in the mounting part 600 and located between the detection module 500 and the test strip 11, which can also play a sealing role to prevent the liquid to be tested from contacting the detection module 500, thereby protecting the detection module 500.
[0059] Furthermore, the light-transmitting component 800 has a protruding retaining part 810 on its side, which is fixedly engaged with the mounting component 600.
[0060] In this embodiment, the retaining portion 810 on the side wall of the light-transmitting element 800 is fixedly engaged with the mounting element 600, which not only ensures that the light-transmitting element 800 is securely installed on the mounting element 600, but also further improves the sealing between the light-transmitting element 800 and the mounting element 600.
[0061] Furthermore, a sealing element is provided at the connection between the light-transmitting element 800 and the mounting element 600 to further improve the sealing performance between the light-transmitting element 800 and the mounting element 600, thereby achieving waterproofing at the connection between the light-transmitting element 800 and the mounting element 600.
