Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in an embodiment of the present invention, a liquid detection device is proposed, comprising: a housing 100, a fixture 200, a box 300, a detection element 400, and a clamping mechanism 500. The housing 100 has an installation cavity, and the housing 100 has a liquid inlet 110 and a liquid outlet 120. The fixture 200 is located in the installation cavity and is used to support the sample carrier 180. The box 300 is located in the installation cavity, and the liquid inlet 110 and the liquid outlet 120 are connected to the box 300. The box 300 is used to contain the liquid to be tested, and the sample carrier 180 can absorb the liquid to be tested. The detection element 400 is located in the housing 100 and in the installation cavity. The detection element 400 is used to detect the liquid to be tested on the sample carrier 180. The clamping mechanism 500 is located in the housing 100 and in the installation cavity. The clamping mechanism 500 is used to move the sample carrier 180 between the fixture 200, the detection element 400, and the box 300.

[0039] In this embodiment of the liquid detection device, the mounting cavity formed inside the housing 100 is used to install the detection components, and the housing 100 serves to house and support the detection components.

[0040] The housing 300 is installed inside the box 100. The housing 300 has a detection chamber into which the liquid to be tested can be injected. Specifically, the box 100 is provided with an inlet 110 and an outlet 120, both of which are connected to the detection chamber. A connecting inlet and a connecting outlet can be provided on the housing 300, and then the connecting inlet is connected to the inlet 110, and the connecting outlet is connected to the outlet 120, respectively, via pipes. Valve bodies can be installed on the inlet 110 and the outlet 120, allowing control of their opening and closing. The liquid to be tested can be injected into the detection chamber for testing.

[0041] The fixture 200 is installed inside the housing 100. The fixture 200 is used to support the sample carrier 180. The sample carrier 180 can adsorb the liquid to be tested in the detection chamber, so that the detection element 400 can detect the composition of the liquid to be tested adsorbed on the sample carrier 180.

[0042] For example, the sample carrier 180 can be absorbent paper. The liquid to be tested can be urine, saliva, medicinal liquid, liquid from a river, etc. Therefore, the liquid detection device provided in this embodiment can realize detection functions in medicine, biology, genetics, environmental protection, etc.

[0043] The clamping mechanism 500 can clamp the sample carrier 180, thereby enabling the clamping mechanism 500 to move the sample carrier 180. Specifically, after the liquid to be tested is injected into the detection chamber, the clamping mechanism 500 can clamp the sample carrier 180 on the fixture 200, then move the sample carrier 180 above the housing 300, and then move the sample carrier 180 deeper into the detection chamber. After the sample carrier 180 adsorbs the liquid to be tested, the clamping mechanism 500 moves the sample carrier 180 to the vicinity of the detection element 400, so that the detection element 400 can detect the composition of the liquid to be tested adsorbed on the sample carrier 180. By moving the sample carrier 180 through the clamping mechanism 500, the function of automatically detecting the liquid to be tested is realized.

[0044] For example, the detection element 400 can detect the components of the liquid to be tested using image recognition technology.

[0045] After the test is completed, the clamping mechanism 500 returns the sample carrier 180 to the fixture 200. Multiple sample carriers 180 can be placed on the fixture 200, allowing for multiple tests and improving test accuracy.

[0046] By assembling the fixture 200, the testing component 400, and the clamping mechanism 500 within the housing 100, the liquid detection device achieves an integrated structure, facilitating user handling and transport. For hazardous testing scenarios, or situations where it is inconvenient to go to a hospital or testing institution for liquid testing, users can carry the liquid detection device to the site for on-site testing, enabling testing anytime, anywhere, thus significantly improving the convenience of liquid testing.

[0047] The housing 100 is equipped with a handle, making it easy for users to pick up the liquid detection device.

[0048] The housing 100 is also equipped with indicator lights and function buttons. The indicator lights are used to indicate the current working status of the liquid detection device. Users can control the liquid detection device by pressing the function buttons.

[0049] The liquid detection device also includes a battery 900, which powers the clamping structure, allowing the liquid detection device to be used independently, regardless of the application environment, making it convenient for outdoor use. Alternatively, in other embodiments, a power outlet can be provided on the housing 100 to enable external power supply.

[0050] Combination Figure 3 and Figure 4 As shown, in the above embodiment, the clamping mechanism 500 includes: a clamping component 510 and a driving component 520. The clamping component 510 is used to clamp the sample carrier 180. The clamping component 510 is disposed on the driving component 520, and the driving component 520 is used to drive the clamping component 510 to move.

[0051] The clamping assembly 510 can clamp and place the sample carrier 180, thereby automatically picking up and placing the sample carrier 180. The driving assembly 520 can drive the clamping assembly 510 to move, thereby realizing the transfer function of the sample carrier 180.

[0052] The clamping assembly 510 and the drive assembly 520 are arranged relatively independently, which facilitates the assembly of the liquid detection device. Moreover, when the clamping assembly 510 or the drive assembly 520 is damaged, the clamping assembly 510 or the drive assembly 520 can be disassembled and replaced separately, which improves the convenience of maintenance and reduces maintenance costs.

[0053] Combination Figure 3 , Figure 4 and Figure 5 As shown, in the above embodiment, the clamping assembly 510 includes: a fixing plate 511, a clamping plate 512, and a first elastic member (not shown in the figure). The fixing plate 511 is disposed on the driving assembly 520. The first end of the clamping plate 512 is rotatably connected to the fixing plate 511, and an opening is formed between the second end of the clamping plate 512 and the fixing plate 511. The sample carrier 180 extends through the opening between the fixing plate 511 and the clamping plate 512. The first elastic member is disposed on the fixing plate 511 and / or the clamping plate 512. The first elastic member is used to drive the fixing plate 511 and the clamping plate 512 to clamp the sample carrier 180.

[0054] The drive assembly 520 is used to move the fixed plate 511. The clamping plate 512 is connected to the fixed plate 511, allowing the fixed plate 511 to move the clamping plate 512. The relative position of the fixed plate 511 and the drive assembly 520 remains unchanged, while the clamping plate 512 can rotate relative to the fixed plate 511. When the sample carrier 180 extends between the fixed plate 511 and the clamping plate 512, the distance between the fixed plate 511 and the clamping plate 512 increases. At this time, the first elastic element is in an elastic deformation state and tends to pull the clamping plate 512 toward the fixed plate 511, ensuring that the clamping plate 512 and the fixed plate 511 stably clamp the sample carrier 180.

[0055] After the sample carrier 180 separates from the fixing plate 511 and the clamping plate 512, the first elastic element pulls the clamping plate 512, thereby reducing the distance between the fixing plate 511 and the clamping plate 512, so as to facilitate the clamping of the sample carrier 180 in the next operation.

[0056] The first elastic element can be a torsion spring, and a rotating shaft is provided between the fixing plate 511 and the clamping plate 512, with the torsion spring sleeved on the rotating shaft.

[0057] The sample carrier 180 is clamped by the fixing plate 511 and the clamping plate 512. Therefore, the clamping assembly 510 has a simple structure and fewer parts, which helps to reduce the failure rate.

[0058] The first elastic element pulls the clamping plate 512 to ensure that the sample carrier 180 is not easily separated from the clamping assembly 510, which helps to improve the stability of the testing process.

[0059] Combination Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, in the above embodiment, the clamping assembly 510 further includes a limiting member 513 and an unlocking member 514. The limiting member 513 is slidably connected to the fixing plate 511. When the clamping assembly 510 places the sample carrier 180, the sample carrier 180 can push the limiting member 513 to move. When the limiting member 513 is pushed to the first position, the limiting member 513 limits the clamping plate 512 to move the second end of the clamping plate 512 away from the fixing plate 511. The unlocking member 514 is provided in the housing 100. When the clamping assembly 510 is in the raised position, the unlocking member 514 abuts against the limiting member 513. The unlocking member 514 is used to push the limiting member 513 to move to the second position so that the limiting member 513 releases the limiting of the clamping plate 512.

[0060] When the clamping assembly 510 picks up the material, the driving assembly 520 drives the clamping assembly 510 to descend. As the sample carrier 180 extends between the fixed plate 511 and the clamping plate 512, the distance between the fixed plate 511 and the clamping plate 512 increases. Under the action of the first elastic member, the fixed plate 511 and the clamping plate 512 clamp the sample carrier 180. After the sample testing is completed, the driving assembly 520 drives the clamping assembly 510 to descend. When the bottom of the sample carrier 180 contacts the fixture 200, the sample carrier 180 cannot descend further. However, when the clamping assembly 510 continues to descend, the top of the sample carrier 180 can push the limiting member 513, that is, the limiting member 513 can move relative to the fixed plate 511.

[0061] The first position is the locking position of the limiting member 513 on the clamping plate 512. As the limiting member 513 moves towards the first position, the distance between the clamping plate 512 and the fixing plate 511 increases, causing the clamping plate 512 and the fixing plate 511 to no longer clamp the sample carrier 180. To prevent the clamping assembly 510 from rising and clamping the sample carrier 180 again, when the limiting member 513 moves to the first position, it limits the clamping plate 512, preventing it from rotating relative to the fixing plate 511, thus maintaining a large distance between the clamping plate 512 and the fixing plate 511. When the clamping assembly 510 rises, the sample carrier 180 is less likely to be lifted by the clamping assembly 510, thus completing the placement process of the sample carrier 180.

[0062] As the clamping assembly 510 rises, the unlocking member 514 contacts the limiting member 513, pushing the limiting member 513 towards a second position. This second position is where the limiting member 513 unlocks the clamping plate 512. When the limiting member 513 is in the second position, it separates from the clamping plate 512, thus releasing the clamping plate 512 from its position. At this time, the first elastic member pulls the clamping plate 512, reducing the distance between the fixing plate 511 and the clamping plate 512, facilitating the clamping of the next sample carrier 180.

[0063] By cooperating with the limiting member 513 and the unlocking member 514, the placement function of the sample carrier 180 is automatically realized without user intervention, simplifying the user's operation and realizing the function of automatic detection, which helps to improve the user's convenience in using the liquid detection device.

[0064] Combination Figure 5 and Figure 6 As shown, in the above embodiment, the limiting member 513 is provided with a first inclined surface 515, and the clamping plate 512 is provided with a second inclined surface 516 and a limiting surface 517. The first inclined surface 515 can move along the second inclined surface 516. When the limiting member 513 is in the first position, the first inclined surface 515 abuts against the limiting surface 517. When the limiting member 513 is in the second position, the first inclined surface 515 separates from the limiting surface 517.

[0065] The limiting member 513 has a first inclined surface 515 machined on it, and the clamping plate 512 has a second inclined surface 516 machined on it. The slopes of the first inclined surface 515 and the second inclined surface 516 can be the same, or the distance between the first inclined surface 515 and the second inclined surface 516 can gradually decrease from bottom to top. During the material handling process, the sample carrier 180 can be set to not contact the limiting member 513, or the sample carrier 180 can only push the limiting member 513 a small distance. In this case, the first inclined surface 515 slides relative to the second inclined surface 516, preventing the clamping plate 512 from rotating too much relative to the fixed plate 511 and causing unstable clamping.

[0066] During the feeding process, as the sample carrier 180 pushes the limiting member 513, the first inclined surface 515 comes into contact with the limiting surface 517. Without the action of external force, the limiting member 513 is difficult to move relative to the clamping plate 512, thereby realizing the limiting function of the clamping plate 512.

[0067] As the clamping assembly 510 rises, the unlocking member 514 located above the clamping assembly 510 pushes the limiting member 513, causing the first inclined surface 515 to separate from the limiting surface 517, thereby releasing the limitation on the clamping plate 512. By processing the surface shapes of the limiting member 513 and the clamping plate 512 accordingly, the limiting function can be achieved without the need for an additional locking structure, which helps to reduce the number of parts and simplify the product structure.

[0068] Combination Figure 5 and Figure 6 As shown, in the above embodiment, the clamping assembly 510 further includes a second elastic member 518. The second elastic member 518 is disposed on the fixing plate 511. When the clamping assembly 510 places the sample carrier 180, the second elastic member 518 is used to push the sample carrier 180 to separate from the fixing plate 511 and / or the clamping plate 512.

[0069] Since the sample carrier 180 has absorbed the liquid to be tested, the surface of the sample carrier 180 may have a certain degree of viscosity. In order to ensure that the sample carrier 180 can be stably separated from the clamping assembly 510, a second elastic member 518 is provided to push the sample carrier 180.

[0070] Specifically, even if the clamping plate 512 and the fixing plate 511 are far apart, the sample carrier 180 may still be attracted to the fixing plate 511 or the clamping plate 512, which may prevent the sample carrier 180 from separating from the clamping assembly 510. When the sample carrier 180 pushes the limiting member 513 to the first position, the second elastic member 518 contacts the sample carrier 180, and the sample carrier 180 pushes the second elastic member 518 to an elastic deformation state. Therefore, the second elastic member 518 has a tendency to push the sample carrier 180 away from the limiting member 513, thereby applying a force to the sample carrier 180 to ensure that the sample carrier 180 can be stably separated from the clamping assembly 510.

[0071] Combination Figure 5 and Figure 6 As shown, in the above embodiment, the second elastic member 518 is provided with a bending portion 5181, and the opening side of the bending portion 5181 is away from the sample carrier 180.

[0072] By setting a portion of the second elastic member 518 as a bent portion 5181, when the sample carrier 180 pushes the second elastic member 518, the second elastic member 518 has a large shape change, thus improving the pushing effect of the second elastic member 518 on the sample carrier 180.

[0073] In the above embodiment, the fixing plate 511 is provided with a first guide surface 5111, and the clamping plate 512 is provided with a second guide surface 5121. The distance between the first guide surface 5111 and the second guide surface 5121 decreases along the second end of the clamping plate 512 to the first end of the clamping plate 512.

[0074] A first guide surface 5111 and a second guide surface 5121 are respectively provided at the bottom of the fixing plate 511 and the clamping plate 512, so that the bottom distance between the fixing plate 511 and the clamping plate 512 is large. During the material handling process, the sample carrier 180 can be stably extended between the fixing plate 511 and the clamping plate 512.

[0075] Specifically, the first guide surface 5111 and the second guide surface 5121 guide the sample carrier 180. Even if the sample carrier 180 is not aligned with the clamping assembly 510, it can still stably extend between the fixing plate 511 and the clamping plate 512 under the guidance of the first guide surface 5111 and the second guide surface 5121, thereby improving the stability of the material handling process and thus improving the stability of the detection function of the liquid detection device.

[0076] Combination Figure 3 , Figure 4 and Figure 8 As shown, in the above embodiment, the driving component 520 includes: a first driving member 521, a second driving member 522, and a third driving member 523. The clamping component 510 is disposed on the first driving member 521, and the first driving member 521 is used to drive the clamping component 510 to reciprocate along a first direction; the first driving member 521 is disposed on the second driving member 522, and the second driving member 522 is used to drive the first driving member 521 to reciprocate along a second direction; the third driving member 523 is disposed on the housing 100, and the second driving member 522 is used to drive the second driving member 522 to reciprocate along a third direction.

[0077] The first driving member 521 can drive the clamping assembly 510 to move along a first direction. The second driving member 522 can drive the first driving member 521 to move, thereby indirectly driving the clamping assembly 510 to move along a second direction. The third driving member 523 can drive the second driving member 522 to move, thereby indirectly driving the clamping assembly 510 to move along a third direction.

[0078] The first driving member 521, the second driving member 522, and the third driving member 523 have different driving directions. For example, the first direction is the Z-axis direction, the second direction is the Y-axis direction, and the third direction is the X-axis direction.

[0079] The clamping assembly 510 is moved by the first driving member 521, the second driving member 522 and the third driving member 523, which can improve the movement flexibility of the clamping assembly 510 and make it easier for the clamping assembly 510 to move the sample carrier 180 to different positions.

[0080] The first driving component 521 can be a ball screw structure. The driving source of the ball screw can be a combination of a motor and a reducer, or a motor and a gear set. Alternatively, the first driving component 521 can be a belt drive structure or a sprocket drive structure. Any structure that can drive the clamping assembly 510 to reciprocate is within the protection scope of this invention and is not specifically limited.

[0081] The structures of the second drive member 522 and the third drive member 523 are the same as those of the first drive member 521.

[0082] The structures of the first driving element 521, the second driving element 522, and the third driving element 523 may be the same or different.

[0083] like Figure 4 As shown, in the above embodiment, the liquid detection device further includes a cleaning mechanism 600, which is disposed in the housing 100 and located in the mounting cavity. The cleaning mechanism 600 is used to clean the housing 300.

[0084] The liquid detection device can perform component analysis on liquids of different compositions and types. After analyzing one liquid sample, the inside of the housing 300 needs to be cleaned to avoid affecting the composition of the next liquid sample.

[0085] Specifically, after completing the component detection of the previous sample of liquid to be tested, the liquid to be tested is discharged from the box 300, and then the inside of the box 300 is cleaned by the cleaning mechanism 600 to remove the residue of the previous sample of liquid to be tested, reduce the impact of two tests, and help improve the accuracy of liquid component detection.

[0086] Combination Figure 4 and Figure 8As shown, in the above embodiment, the housing 300 includes: a base 310 and a cover 320, the cover 320 being rotatably connected to the base 310, the base 310 having a test chamber, and the cover 320 being used to open or close the test chamber; the cleaning mechanism 600 includes: a pump assembly 610 and a flipping assembly 620, the pump assembly 610 being disposed in the housing 100 and being used to draw the liquid to be tested into or out of the test chamber; the cover 320 being connected to the flipping assembly 620, and the flipping assembly 620 being used to drive the cover 320 to rotate.

[0087] The cover 320 can rotate relative to the base 310, thereby opening or closing the test chamber. When testing the components of the liquid to be tested, the cover 320 must be kept open. When cleaning the test chamber, the cover 320 must be kept closed.

[0088] The pump assembly 610 can drive the liquid to be tested to flow into or out of the detection chamber. Specifically, when it is necessary to detect the composition of the liquid to be tested, the pump assembly 610 draws the liquid to be tested into the detection chamber, and when the test is completed, the pump assembly 610 draws the liquid out of the detection chamber.

[0089] When cleaning the test chamber is required, the cover 320 is first flipped by the flipping component 620, closing the test chamber. The pump assembly 610 then pumps clean water into the test chamber. As the water is pumped in, it flushes the liquid on the inner wall of the test chamber, thus achieving the cleaning function. After cleaning, the pump assembly 610 extracts the wastewater, and the flipping component 620 flips the cover 320, opening the test chamber so that the sample carrier 180 can extend into the housing 300.

[0090] By closing the test chamber with the cover 320, it is ensured that the clean water injected into the test chamber is not easily splashed out, thereby ensuring the cleanliness of the chamber 100. Moreover, when the test chamber is closed with the cover 320, the chamber 300 remains closed, which can improve the flushing effect of clean water on the inner wall of the chamber 300.

[0091] Combination Figure 4 , Figure 8 and Figure 9 As shown, in the above embodiment, the flipping assembly 620 includes: a paddle 621 and a linkage assembly 622. The driving assembly 520 is used to drive the paddle 621 to rotate; the linkage assembly 622 is connected to the paddle 621 and is used to drive the cover 320 to rotate.

[0092] The drive component 520 can not only drive the clamping component 510 to move, but also drive the paddle 621 to rotate, thereby enabling the clamping mechanism 500 and the cleaning mechanism 600 to work together.

[0093] Specifically, when the drive assembly 520 moves the clamping assembly 510 toward the housing 300, the drive assembly 520 drives the lever 621 to rotate. The lever 621 then moves the connecting rod assembly 622, which in turn moves the cover 320 to open the cleaning chamber, ensuring that the sample carrier 180 can be stably inserted into the housing 300. When the drive assembly 520 moves the clamping assembly 510 away from the housing 300, the connecting rod assembly 622 moves the cover 320 to close the test chamber, preventing liquid from splashing out of the test chamber.

[0094] Since the clamping mechanism 500 is linked with the cleaning mechanism 600, there is no need to set a separate drive component for the cleaning mechanism 600. This simplifies the product structure, reduces the number of parts, and thus reduces the size of the liquid detection device, improving the user's portability of the liquid detection device.

[0095] Combination Figure 4 , Figure 9 and Figure 10 As shown, in the above embodiment, the linkage assembly 622 includes: a first rotating shaft 623, a first rod 624, a second rod 625, a third rod 626, and a second rotating shaft 627. The first rotating shaft 623 is rotatably connected to the housing 100, and a paddle 621 is disposed on the first rotating shaft 623. The first end of the first rod 624 is disposed on the first rotating shaft 623. The first end of the second rod 625 is rotatably connected to the second end of the first rod 624. The first end of the third rod 626 is rotatably connected to the second end of the second rod 625. The second rotating shaft 627 is rotatably connected to the housing 100, and the cover 320 is fixed to the second rotating shaft 627. The second end of the third rod 626 is disposed on the second rotating shaft 627.

[0096] This embodiment describes one configuration of the linkage assembly 622, which consists of three connecting rods and two rotating shafts, used to realize the transmission function between the paddle 621 and the cover 320. In other embodiments, the number of connecting rods or rotating shafts can be adjusted according to actual usage requirements.

[0097] In the above embodiment, the linkage assembly 622 further includes a third elastic element (not shown in the figure), which is sleeved on the second rotating shaft 627 and is used to drive the cover 320 to close the test chamber.

[0098] When the cover 320 is in the open state, the third elastic element is in an elastic deformation state, and the third elastic element has a tendency to push the cover 320 to close the test chamber. When the drive assembly 520 moves away from the housing 300, the third elastic element drives the second rotating shaft 627 to rotate, so that the second rotating shaft 627 drives the cover 320 to close the test chamber. By setting the third elastic element on the second rotating shaft 627 to drive the cover 320 to flip, it is ensured that the cover 320 can stably close the test chamber.

[0099] It should be noted that the elastic potential energy stored in the third elastic element is provided by the drive assembly 520. Therefore, there is no need to set up a separate electric drive component to drive the cover 320 to close the test chamber, which helps to simplify the product structure.

[0100] Combination Figure 4 and Figure 12 As shown, in the above embodiment, the box body 300 further includes an overflow prevention tube 330, the first end of which is disposed on the bottom wall of the test chamber, and the second end of which is lower than the opening of the test chamber.

[0101] If too much liquid is injected into the test chamber 300, it may overflow. Therefore, to prevent overflow, an anti-overflow tube 330 is installed inside the test chamber 300.

[0102] Specifically, the bottom of the anti-overflow tube 330 is connected to the bottom wall of the test chamber, and an outlet can be provided on the bottom wall of the test chamber. Since the second end of the anti-overflow tube 330 is lower than the opening of the test chamber, as the liquid level of the liquid to be tested in the test chamber rises, the liquid to be tested can flow out through the anti-overflow tube 330, and is not likely to overflow the box 300, thus avoiding the situation where the liquid to be tested contaminates the liquid detection device and reducing the amount of cleaning work required by the user inside the liquid detection device.

[0103] The outlet on the bottom wall of the test chamber can be connected to the drain port 120, or a liquid discharge port can be separately provided on the housing 100 and connected to the outlet on the bottom wall of the test chamber.

[0104] In the above embodiment, the cleaning mechanism 600 further includes a liquid level detection element (not shown in the figure), which is disposed in the housing 300 and located inside the test chamber.

[0105] The liquid level detection device can detect the liquid level inside the box 300. The liquid level detection device can display the detected liquid level on the display on the outer surface of the box 100 in real time, so that the user can know the current liquid level inside the box 300 in a timely manner, which is convenient for the user to operate.

[0106] It can also be set to issue an alarm when the liquid level detection device detects that the liquid level in the box 300 has reached a set height, thereby reminding the user to stop injecting the liquid to be tested into the box 300, thus improving the user's awareness of the food safety of the liquid detection device.

[0107] For example, the liquid level detection element can be a liquid level sensor.

[0108] like Figure 8As shown, in the above embodiment, the pump body assembly 610 includes: a first pump body 611 and a second pump body 612. The first pump body 611 is used to draw the liquid to be tested into the test chamber; the second pump body 612 is used to draw the liquid to be tested out of the test chamber.

[0109] The function of pumping the liquid to be tested into or out of the test chamber is achieved by different pump bodies. If one pump body fails, the other pump body can continue to work, reducing the impact on the functionality of the liquid testing device.

[0110] Combination Figure 8 and Figure 11 As shown, in the above embodiment, the housing 100 includes: a housing body 130 and a mounting plate 140. The mounting plate 140 is disposed on the housing body 130 and divides the housing body 130 into a first mounting cavity and a second mounting cavity. The jig 200, the clamping mechanism 500 and the driving mechanism are located in the first mounting cavity, and the pump assembly 610 is located in the second mounting cavity.

[0111] Different components are installed in the first and second mounting cavities to avoid interference or influence between them. For example, the pump assembly 610 is used to pump the liquid to be tested. To prevent the pipeline on the pump assembly 610 from contaminating the sample carrier 180 due to leakage of the liquid to be tested, the pump assembly 610 and the fixture 200 are placed in different cavities.

[0112] In the above embodiment, the jig 200 is detachably connected to the box body 130 so that the jig 200 can avoid the mounting plate 140.

[0113] The fixture 200 can be disassembled and installed on the housing body 130, which facilitates the maintenance and cleaning of the fixture 200.

[0114] For example, after prolonged use of the fixture 200, the fixture 200 can be disassembled from the box body 130 and then removed from the box body 130, thereby cleaning the fixture 200 and preventing the fixture 200 from contaminating the sample carrier 180.

[0115] Alternatively, when using different models of sample carriers 180, the fixture 200 can be disassembled from the housing body 130, and then the fixture 200 that matches the sample carrier 180 can be installed. The detachable structure of the fixture 200 improves the flexibility of using the liquid detection device.

[0116] Specifically, the enclosure 100 also includes a door 170, which is rotatably connected to the enclosure body 130. The enclosure body 130 is provided with an installation port, and the door 170 is used to open or close the installation port. The fixture 200 can be taken out or put in through the installation port.

[0117] Combination Figure 8 and Figure 11 As shown, in the above embodiment, the mounting plate 140 is rotatably connected to the box body 130, the pump body assembly 610 is disposed on the mounting plate 140, and the mounting plate 140 can be flipped toward one side of the first mounting cavity.

[0118] The first mounting cavity houses the fixture 200, the clamping mechanism 500, and the drive mechanism, thus providing a larger space. The second mounting cavity, however, only houses the pump body assembly 610, resulting in a smaller space. When assembling the pump body assembly 610, the mounting plate 140 can be flipped, causing the pump body assembly 610 to rotate. When the pump body assembly 610 is rotated into the second mounting cavity, assembly and maintenance of the pump body assembly 610 become more convenient for the user.

[0119] When no maintenance is required on the pump body assembly 610, the mounting plate 140 is locked to the housing body 130 by screws or other means to prevent the pump body assembly 610 from shaking.

[0120] In practical applications, to improve ease of use, the mounting port is used to be located in the first mounting cavity.

[0121] like Figure 13 As shown, in the above embodiment, the box 100 further includes: a support plate 150, the support plate 150 is disposed on the box body 130, the support plate 150 is provided with a snap-fit ​​hole 151, and the fixture 200 is provided with a snap-fit ​​part 210, the snap-fit ​​part 210 can be inserted into the snap-fit ​​hole 151.

[0122] The support plate 150 has a snap-fit ​​hole 151 machined on it, and the fixture 200 has a snap-fit ​​part 210 machined on it. When the snap-fit ​​part 210 is inserted into the snap-fit ​​hole 151, the fixture 200 is fixed to the support plate 150.

[0123] The fixture 200 and the support plate 150 are fixed by a snap-fit ​​mechanism, making it easier to assemble and disassemble the fixture 200. Furthermore, it eliminates the need for additional screws or other components, reducing the number of parts required. Of course, in other embodiments, screws or pins can also be used for locking.

[0124] like Figure 13 As shown, in the above embodiment, the box 100 further includes a limiting plate 160, which is disposed on the support plate 150 and contacts the top of the fixture 200 to restrict the bottom of the fixture 200 from separating from the box body 130.

[0125] The limiting plate 160 can limit the fixture 200, prevent the fixture 200 from being misaligned due to shaking, and ensure that the sample carrier 180 can stably extend into or out of the fixture 200.

[0126] like Figure 13 As shown, in the above embodiment, the jig 200 has a groove 220 on its side, and the groove 220 is located on one side of the support plate 150.

[0127] Since the jig 200 and the support plate 150 are fixed by a snap-fit ​​mechanism, the user needs to apply force to the side of the jig 200 when it needs to be assembled or disassembled. By providing a groove 220 on the side wall of the jig 200, the user's hand can be inserted into the groove 220, making it less likely for the user's hand to slide against the jig 200, thus improving the ease of assembling and disassembling the jig 200.

[0128] The groove 220 is set close to the support plate 150. When the user applies a small force to the fixture 200, the fixture 200 can be deformed locally, thereby causing the snap-fit ​​part 210 to extend into or out of the snap-fit ​​hole 151.

[0129] Of course, in other embodiments, to facilitate user operation, a raised structure to increase friction can also be provided on the surface of the fixture 200.

[0130] like Figure 13 As shown, in the above embodiment, the liquid detection device further includes: a collection element 700, which is disposed in the housing 100 and faces the fixture 200. The collection element 700 is used to collect the specification information of the sample carrier 180.

[0131] The data acquisition unit 700 is used to acquire the specification information of the sample carrier 180. The data acquisition unit 700 displays the acquired specification information on a display on the outer surface of the housing 100, or the data acquisition unit 700 transmits the acquired specification information to the user terminal wirelessly. After obtaining the specification information, the user can determine whether the type of sample carrier 180 on the current fixture 200 is correct, thereby improving the accuracy of the testing process.

[0132] Combination Figure 13 and Figure 14 As shown, in the above embodiment, the fixture 200 is provided with a plurality of insertion slots 230, and the sample carrier 180 can be inserted into the insertion slots 230; the opening of the insertion slot 230 is provided with a guide slope 240.

[0133] The sample carrier 180 can be inserted into the insertion slot 230. The insertion slot 230 plays a role in bearing and limiting the sample carrier 180, ensuring that the sample carrier 180 is not easy to shake, thereby improving the stability of the clamping structure for picking up and putting down the sample carrier 180.

[0134] In this embodiment, the fixture 200 is provided with two rows of insertion slots 230. In actual use, one row of insertion slots 230 is used to place unused sample carriers 180. After the sample carriers 180 absorb the liquid to be tested, the used sample carriers 180 can be placed in the other row of insertion slots 230 to avoid the sample carriers 180 becoming disordered. Of course, the used sample carriers 180 can also be returned to their original positions.

[0135] A guide slope 240 is provided at the opening of the insertion groove 230. The guide slope 240 guides the sample carrier 180, ensuring that the sample carrier 180 can be stably inserted into the insertion groove 230. Moreover, by providing the guide slope 240, the width of the opening of the insertion groove 230 is larger, while the width in the middle and at the bottom is smaller. This allows the sample carrier 180 to be tightly inserted into the insertion groove 230, preventing the sample carrier 180 from shaking.

[0136] like Figure 7 As shown, in the above embodiment, the liquid detection device further includes a position detection component 800, which is disposed in the housing 100 and is used to detect the position of the sample carrier 180 and the clamping mechanism 500.

[0137] The position detection component 800 includes multiple position sensors. The position sensors can detect whether the sample carrier 180 is placed at a certain position on the fixture 200, and the position sensors can also detect whether the clamping mechanism 500 has moved into place, which helps to improve the stability of the cooperation between the components.

[0138] Specifically, the position detection component 800 includes six position sensors. When the clamping component 510 descends to the picking position, the first position sensor detects whether the sample carrier 180 is placed on the fixture 200. The second position sensor detects whether the clamping component 510 has descended to the gripping position. After the gripping component rises, the third position sensor detects whether the sample carrier 180 is gripped on the gripping component. The fourth position sensor detects whether the clamping component 510 has risen to a designated position. When the clamping component 510 rises to the designated position, the drive component 520 moves the gripping component horizontally. The fifth position sensor detects whether the unlocking component 514 has unlocked the locking component. The sixth position sensor detects whether the sample carrier 180 has reached the position where it extends into the housing 300. The installation positions of the six position sensors are not specifically limited, as long as they can achieve the corresponding detection functions.

[0139] In one possible embodiment, the liquid detection device further includes a communication module capable of data transmission with the operator's terminal. The detection results of the liquid to be detected can be transmitted to the operator's terminal via the communication module. The operator can also control the liquid detection device remotely, making the liquid detection device provided in this embodiment suitable for environments where it is inconvenient for the operator to go to the site.

[0140] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention.
