Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and specifically to a water quality testing instrument. Background Technology

[0002] As people's living standards improve, their requirements for water quality are becoming increasingly stringent. For example, higher requirements are being placed on water quality parameters such as pH value, total chlorine, residual chlorine, total alkalinity, and total hardness. Various water quality testing instruments exist for this purpose, but most can only test one water quality parameter at a time. However, in daily production and life, multiple water quality parameters are usually required, necessitating multiple sampling and testing processes, making water quality testing cumbersome and inefficient. Utility Model Content

[0003] In view of this, the present invention aims to provide a water quality analyzer to improve the water quality detection efficiency of the water quality analyzer.

[0004] This utility model provides a water quality analyzer, which includes a housing, a testing carrier, and a testing unit. The housing has a testing position and a waiting position, with the waiting position located on at least one side of the testing position in a first direction. The testing carrier includes a support platform with multiple holding positions arranged at intervals along the first direction. Each holding position is used to place at least one testing bottle. The support platform is movably disposed within the housing along the first direction so that the testing bottle can move between the waiting position and the testing position. The testing unit includes a light source and a light sensor, both of which are disposed at the testing position. The light source emits light to the testing bottle located at the testing position, and the light sensor receives the light passing through the testing bottle.

[0005] When performing water quality testing, the water sample to be tested is first placed into a test bottle, and the test liquid is obtained inside the bottle. Then, the test bottle containing the test liquid is placed on a support position of the support platform, with some test bottles in the test position and others in the waiting position. Next, the support platform is moved along a first direction so that each test bottle passes through the test position. When a test bottle is in the test position, light is emitted from the light source of the detection unit and received by the light sensor of the detection unit, ultimately obtaining the water quality parameters of the water sample. By setting multiple support positions on the support platform, each position for holding at least one test bottle, multiple test bottles can be used simultaneously to collect water samples. By moving the support platform so that multiple test bottles pass through the test positions, multiple water quality parameters of the water sample can be detected. This simplifies the water quality testing process, saves testing time and manpower, and improves the efficiency of water quality testing. Attached Figure Description

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

[0038] Currently, water quality testing methods mainly rely on colorimetry, with the primary objects of colorimetric comparison being the fully reacted test liquid, tablets, and test strips. Among these, water quality analyzers used for testing tablets are complex to operate and have low testing efficiency; those used for testing test strips are simple to operate but have relatively large detection errors; and those used for testing liquids are widely used due to their simplicity and high accuracy.

[0039] In related technologies, water quality analyzers used to detect liquids can only collect one water sample at a time and can only perform one water quality parameter test on the sample at a time. For situations such as swimming pools that require multiple water quality parameter tests, it is necessary to repeatedly collect and test the water sample. The entire testing process is cumbersome, time-consuming, and labor-intensive, resulting in low efficiency in water quality testing.

Figure 2 The image shown is a cross-sectional view of a water quality testing instrument provided in one embodiment of this utility model (with the support platform in the first extreme position). Figure 3 The image shown is a perspective view of a water quality testing instrument provided in one embodiment of this utility model (with the support platform in the second extreme position). Figure 4 The image shown is a cross-sectional view of a water quality testing instrument provided in one embodiment of this utility model (with the support platform in the second extreme position). Figure 5 The image shown is an exploded view of a water quality testing instrument provided in one embodiment of this utility model.

[0041] refer to Figures 1 to 5 According to one embodiment of the present invention, a water quality analyzer includes a housing 1, a detection carrier 2, and a detection unit 3. The detection carrier 2 includes a support platform 21 with multiple support positions arranged along a first direction. Each support position is used to place at least one test bottle 22. The housing 1 has a detection position 11 and a waiting position 12. The waiting position 12 is located on at least one side of the detection position 11 along the first direction. The support platform 21 is movably disposed within the housing 1 along the first direction so that the test bottle 22 can move between the waiting position 12 and the detection position 11. The detection unit 3 includes a light source 31 and a light sensor 32, both of which are disposed at the detection position 11. The light source 31 is used to emit light to the test bottle 22 located at the detection position 11, and the light sensor 32 is used to receive the light passing through the test bottle 22.

[0042] The test bottle 22 is used to contain the test liquid. The test liquid can be understood as the liquid after the water sample to be tested is thoroughly mixed with the liquid reagent. Of course, when it is necessary to zero the water quality analyzer, the test liquid may only include the water sample to be tested, without including the liquid reagent.

[0043] In this process, when the light emitted by the light source 31 passes through the detection bottle 22, a specific type of light is absorbed by the detection liquid inside the bottle 22. The degree to which the detection liquid absorbs this specific light is related to the color of the liquid. The light after being absorbed by the detection liquid is received by the light sensor 32. By transmitting the light data received by the light sensor 32 to the processor, the water quality parameters can be obtained through processing the light data.

[0044] When the water quality analyzer of this embodiment performs water quality testing, firstly, the water sample to be tested is placed into the test bottle 22, and the test liquid is obtained in the test bottle 22; then, the test bottle 22 containing the test liquid is placed on the support position of the support platform 21, with some test bottles 22 located at the test position 11 and others located at the waiting position 12; then, the support platform 21 is moved along the first direction so that each test bottle 22 passes through the test position 11. When the test bottle 22 is located at the test position 11, light is emitted from the light source 31 of the detection unit 3 towards the test bottle 22, and the light sensor 32 of the detection unit 3 receives the light passing through the test bottle 22, ultimately obtaining the water quality parameters of the water sample to be tested. By setting multiple bearing positions on the bearing platform 21, each bearing position is used to place at least one test bottle 22, multiple test bottles 22 can be used to collect water samples to be tested at the same time. By moving the bearing platform 21, multiple test bottles 22 can pass through the test position 11, thereby realizing the detection of multiple water quality parameters of the water sample to be tested. This simplifies the water quality testing operation process, saves testing time and manpower, and improves the efficiency of water quality testing.

[0045] Preferably, one test bottle 22 is placed in each carrier position. In other embodiments, two or more test bottles 22 may be placed in each carrier position.

Figure 7 The image shown is a top view of the support platform of a water quality tester provided in one embodiment of this utility model. Figure 8 The image shown is a perspective view of the support platform of a water quality testing instrument provided in another embodiment of this utility model. Figure 9 The image shown is a top view of the support platform of a water quality tester provided in another embodiment of this utility model. Figure 10 The image shown is a perspective view of the testing bottle of a water quality tester provided in one embodiment of this utility model. Figure 11 The image shown is a perspective view of the array block of a water quality tester provided in one embodiment of this utility model. Figure 12 The image shown is a perspective view of the row cover of a water quality tester provided in one embodiment of this utility model.

[0047] In some embodiments, such as Figures 6 to 9As shown, the support platform 21 has a carrier groove, multiple first light-transmitting holes 212, and multiple second light-transmitting holes 213. The support position is set inside the carrier groove, so that the test bottle 22 is placed inside the carrier groove. The first light-transmitting holes 212 and second light-transmitting holes 213 correspond one-to-one with the test bottle 22, and both the first light-transmitting holes 212 and second light-transmitting holes 213 are connected to the carrier groove. The light source 31 and the light sensor 32 are both set outside the carrier groove 211. The first light-transmitting holes 212 allow light emitted by the light source 31 to pass through, and the second light-transmitting holes 213 allow light passing through the test bottle 22 to pass through.

[0048] By setting a carrier trough on the support platform 21 and placing the support position inside the carrier trough 211, the trough wall can be used to block external light, reducing the amount of external light shining on the test bottle 22 and affecting the test results, thereby improving the accuracy of the water quality tester's test results.

[0049] Furthermore, by providing a first light-transmitting hole 212 and a second light-transmitting hole 213 that communicate with the carrier slot 211 on the support platform 21, the light emitted by the light source 31 can enter the detection bottle 22 located at the detection position 11 through the first light-transmitting hole 212, and the light passing through the detection bottle 22 can enter the light sensor 32 through the second light-transmitting hole 213.

[0050] Preferably, the color of the support platform 21 is black, dark gray, or other colors with low light transmittance.

[0051] By setting the support platform 21 to a color with low light transmittance, the amount of external light shining on the test bottle 22 can be effectively reduced, thus reducing the impact on the test results and further improving the accuracy of the water quality tester's results.

[0052] In some embodiments, such as Figures 5 to 11 As shown, the light source 31 and the light sensor 32 are arranged on opposite sides of the support platform 21 in the second direction. The first light-transmitting hole 212 and the second light-transmitting hole 213 are also arranged on opposite sides of the support platform 21 in the second direction. The detection bottle 22 includes a light-inlet surface 222 and a light-outlet surface 223 arranged opposite to each other along the second direction. The first light-transmitting hole 212 corresponds to the light-inlet surface 222, and the second light-transmitting hole 213 corresponds to the light-outlet surface 223. The second direction is perpendicular to the first direction.

[0053] When detecting the liquid reagent in the detection bottle 22 located at the detection position 11, the light emitted by the light source 31 passes through the first light-transmitting hole 212 along the first direction, and then illuminates the light-inlet surface 222 of the detection bottle 22 along the first direction and enters the detection bottle 22; part of the light entering the detection bottle 22 is absorbed by the liquid reagent in the detection bottle 22, and then the remaining light is emitted through the light-exiting surface 223 of the detection bottle 22 along the first direction, and then passes through the second light-transmitting hole 213 along the first direction and enters the photosensitive sensor 32.

[0054] By designing the light source 31, light sensor 32, first light-transmitting hole 212, second light-transmitting hole 213, and detection bottle 22 as described above, the light emitted by the light source 31 only needs to propagate along the first direction to enter the light sensor 32, without the need for other optical elements to change the direction of light propagation. This simplifies the water quality analyzer and reduces its cost.

[0055] In other embodiments, the light source 31 and the light sensor 32 may be positioned on the same side of the detection bottle 22, or they may be positioned on adjacent sides of the detection bottle 22. In this case, the direction of light propagation can be changed by adding optical elements such as a reflector inside the support platform 21, so that the light emitted by the light source 31 can enter the detection bottle 22, and the light passing through the detection bottle 22 can enter the light sensor 32.

[0056] In some embodiments, the orthographic projection of the first light-transmitting hole 212 onto the light-inlet surface 222 is located inside the edge of the light-inlet surface 222.

[0057] Understandably, during water quality testing, the light incident on the light-receiving surface 222 of the test bottle 22 is the effective incident light. This effective incident light will enter the test bottle 22 and be absorbed by the test liquid inside. However, light incident on the test bottle 22 other than on the light-receiving surface 222 may not enter the test bottle 22, or, if it does enter, it may not exit through the light-emitting surface 223 of the test bottle 22. Therefore, to improve the accuracy of the test results, ideally, all light illuminating the light-receiving surface 222 of the test bottle 22 should originate from the first light-transmitting hole 212.

[0058] By setting the orthographic projection of the first light-transmitting hole 212 on the light-inlet surface 222 to be located inside the edge of the light-inlet surface 222, it is easier to ensure that the light illuminating the light-inlet surface 222 of the test bottle 22 all comes from the first light-transmitting hole 212, thereby improving the accuracy of the water quality tester's test results.

[0059] In some embodiments, the orthographic projection of the second light-transmitting hole 213 onto the light-emitting surface 223 is located inside the edge of the light-emitting surface 223.

[0060] Understandably, during water quality design, the light emitted through the light-emitting surface 223 and projected onto the second light-transmitting aperture 213 is considered effective emitted light, which is received by the light sensor 32. Furthermore, only the light emitted through the light-emitting surface 223 is absorbed by the detected liquid; light emitted from other surfaces (such as the light-emitting surface 223) and projected onto the second light-transmitting aperture 213 is light that has not been absorbed by the detected liquid. This is because, ideally, all light entering the light sensor 32 should be light that has been absorbed by the detected liquid to improve the accuracy of the detection results.

[0061] By placing the orthographic projection of the second light-transmitting hole 213 on the light-emitting surface 223 inside the edge of the light-emitting surface 223, it is easier to ensure that the light received by the light sensor 32 comes from the light emitted from the light-emitting surface 223, that is, the light that passes through the detected liquid, thereby improving the accuracy of the water quality tester's detection results.

[0062] In other embodiments, the orthographic projection of the first light-transmitting aperture 212 onto the light-incident surface 222 may overlap with the light-incident surface 222. The orthographic projection of the second light-transmitting aperture 213 onto the light-emitting surface 223 may overlap with the light-emitting surface 223.

[0063] To make the technical solution of this utility model easier to understand, the following description uses the example of the first direction being consistent with the front-back direction and the second direction being consistent with the left-right direction. The front-back direction and the left-right direction are shown in the figure.

[0064] For example, such as Figure 2 and Figure 4 As shown, the detection position 11 is located behind the waiting position 12. The support platform 21 is movable in the front-to-back direction, allowing the detection bottle 22 to move between the detection position 11 and the waiting position 12. Specifically, when the support platform 21 moves backward, the detection bottle 22 can move from the waiting position 12 to the detection position 11; when the support platform 21 moves forward, the detection bottle 22 can move from the detection position 11 to the waiting position 12. Figure 5 , Figure 6 and Figure 8 As shown, the first light-transmitting hole 212 is located on the right side wall of the carrier groove 211, the second light-transmitting hole 213 is located on the left side wall of the carrier groove 211, the light source 31 is located on the right side of the support platform 21, and the light sensor 32 is located on the left side of the support platform 21. Figure 10 and Figure 11 As shown, the right side of the test bottle 22 is the light-inlet surface 222, and the left side of the test bottle 22 is the light-outlet surface 223.

[0065] When detecting the detection liquid in the detection bottle 22 located at the detection position 11, the light source 31 emits light to the left. The light passes through the first light-transmitting hole 212 to the left and illuminates the light-inlet surface 222 of the detection bottle 22. After a portion of the light is absorbed by the detection liquid in the detection bottle 22, the light exits to the left through the light-exiting surface 223 of the detection bottle 22, and then passes through the second light-transmitting hole 213 to the left and enters the light sensor 32.

[0066] In some embodiments, such as Figure 10 and Figure 11 As shown, the test bottle 22 also includes multiple light-blocking surfaces 224. The light transmittance of the light-blocking surfaces 224 is less than that of the light-incoming surfaces 222, and the light transmittance of the light-blocking surfaces 224 is less than that of the light-outcoming surfaces 223.

[0067] The light-blocking surface 224 can be made into a frosted surface, or the color of the light-blocking surface 224 can be made into a color with low light transmittance, such as black or dark gray, thereby reducing the light transmittance of the light-blocking surface 224.

[0068] As described above, during water quality testing, the light incident on the light-incoming surface 222 of the test bottle 22 is the effective incident light, and the light exiting through the light-exiting surface 223 and reaching the second light-transmitting hole 213 is the effective emitted light. Therefore, by setting the surfaces other than the light-incoming surface 222 and the light-exiting surface 223 as light-blocking surfaces 224, the amount of light passing through these surfaces can be reduced, thereby increasing the amount of effective incident light and effective emitted light, and improving the accuracy of the water quality analyzer's test results.

[0069] By setting the transmittance of the light-blocking surface 224 to be less than that of the light-inlet surface 222, and setting the transmittance of the light-blocking surface 224 to be less than that of the light-outlet surface 223, the amount of light passing through the surface of the test bottle 22 other than the light-inlet surface 222 and the light-outlet surface 223 can be reduced, thereby further improving the accuracy of the water quality tester's test results.

[0070] In some embodiments, such as Figures 6 to 9 As shown, a light-blocking plate 2111 is provided inside the carrier slot, which divides the carrier slot into multiple carrier cavities 2113. Each carrier position corresponds to one of the carrier cavities 2113, and the carrier cavities 2113 are used to place the test bottles 22.

[0071] Preferably, a test bottle 22 is placed in each bearing cavity 2113.

[0072] By installing a light-blocking plate 2111 inside the carrier slot, adjacent test bottles 22 can be separated, and light from adjacent test bottles 22 can be blocked, preventing the light from adjacent test bottles 22 from interfering with each other. For example, for the test bottle 22 located at test position 11, the light-blocking plate 2111 can block the light from the test bottle 22 located at waiting position 12, preventing the test bottle 22 located at test position 11 from receiving light from the test bottle 22 located at waiting position 12, which would affect the water quality parameters of the liquid being tested in the test bottle 22 located at test position 11, thereby further improving the accuracy of the water quality analyzer's test results.

[0073] Optionally, the light-blocking plate 2111 may be black, dark gray, or other colors with low light transmittance.

[0074] Optionally, there are multiple light-blocking plates 2111, and the multiple light-blocking plates 2111 are arranged at intervals along the first direction.

[0075] For example, such as Figures 6 to 9As shown, there are multiple light-blocking plates 2111. These multiple light-blocking plates 2111 are arranged at intervals along the front-back direction and divide the carrier slot into multiple carrier cavities 2113. Each light-blocking plate 2111 is used to separate the detection bottles 22 located on its front and back sides to prevent the light from the detection bottles 22 located on its front and back sides from interfering with each other.

[0076] In some embodiments, such as Figures 10 to 12 As shown, the test bottle 22 includes a bottle body 225 and a bottle cap 226. The bottle body 225 has a container opening 2251 for the test liquid to enter and exit. The bottle cap 226 is detachably connected to the bottle body 225 and seals the container opening 2251. Both the light-inlet surface 222 and the light-outlet surface 223 are located on the bottle body 225. The light transmittance of the bottle cap 226 is less than that of the bottle body 225. A reagent reservoir is located on the side of the bottle cap 226 facing the bottle body 225, and the reagent reservoir contains dried reagent.

[0077] For example, the bottle cap 226 can be set to black to reduce the light transmittance of the bottle cap 226.

[0078] When conducting water quality testing, the water sample to be tested is placed into bottle 225 and then capped with cap 226. The water sample to be tested is thoroughly mixed with the reagent in cap 226 by shaking the test bottle 22 to form the test liquid.

[0079] By setting the light transmittance of the cap 226 to be lower than that of the bottle body 225, the amount of external light entering the test bottle 22 through the cap 226 can be reduced, further improving the accuracy of the water quality analyzer's test results. By placing the dried reagent inside the cap 226, the operation of adding reagent to the bottle body 225 can be eliminated, further simplifying the water quality testing process and improving the water quality analyzer's testing efficiency.

[0080] The reagent can be dried and fixed in the reagent slot of the bottle cap 226. By sealing the reagent slot or the bottle cap 226, the reagent is prevented from deteriorating or becoming ineffective. For example, aluminum foil can be used to seal the opening of the reagent slot, or the bottle cap 226 can be completely sealed in an aluminum foil bag to achieve airtight preservation of the reagent. After the water sample to be tested is put into the bottle body 225, the aluminum foil is first removed, and then the bottle cap 226 is placed on the bottle body 225.

[0081] Optionally, the bottle cap 226 is interference-fitted with the bottle body 225 to achieve a sealed connection between the bottle cap 226 and the bottle body 225.

[0082] Both the bottle cap 226 and the bottle body 225 can be made of plastic.

[0083] In some embodiments, such as Figure 10 and Figure 11 As shown, multiple bottles 225 are connected in sequence to form a row block, and the row block is provided with a handle 2253.

[0084] By connecting multiple bottles 225 to form a block, and providing a handle 2253 to the block, the block can be held during water sample collection, allowing it to be inserted into the water sample to be tested, ensuring that each bottle 225 contains the water sample. This improves the sampling efficiency of the water sample and further enhances the water quality detection efficiency of the water quality analyzer.

[0085] In addition, by connecting multiple bottles 225 to form a block, it is convenient to carry multiple bottles 225 and effectively prevent bottles 225 from being lost.

[0086] Figure 12 The image shown is a perspective view of the manifold cover of a water quality analyzer according to one embodiment of the present invention. In some embodiments, such as... Figure 10 and Figure 12 As shown, multiple bottle caps 226 are connected in sequence to form a row of caps, and the row of caps is provided with a cap handle 2263.

[0087] By connecting multiple bottle caps 226 to form a row of caps, and providing a handle 2263 to the row of caps, after water samples are collected from bottle 225, the row of caps can be moved by holding the handle 2263, and the multiple bottle caps 226 can be respectively placed on the corresponding bottle 225. This improves the sampling efficiency of the water sample to be tested, and further enhances the water quality testing efficiency of the water quality analyzer.

[0088] In addition, by connecting multiple bottle caps 226 to form a row of caps, it is convenient to carry multiple bottle caps 226 and effectively prevent the bottle caps 226 from being lost.

[0089] In some embodiments, such as Figure 10 and Figure 11 As shown, the row of blocks has a block identifier 2254 for indicating direction.

[0090] For example, such as Figure 10 and Figure 11 As shown, block identifier 2254 is an arrow, and the arrow points to the front of the row of blocks.

[0091] By providing block labels 2254 for indicating direction on the blocks, incorrect placement of the blocks can be avoided, making it easier to quickly place the blocks into the bearing positions of the bearing platform 21, which is beneficial to further improve the water quality detection efficiency of the water quality analyzer.

[0092] In some embodiments, such as Figure 10 and Figure 12 As shown, the row of covers is equipped with cover markings 2264 for indicating direction.

[0093] For example, such as Figure 10 and Figure 12As shown, the cover identifier 2264 is an arrow, and the arrow points to the front of the row of covers.

[0094] By providing a directional label 2264 on the row of caps, incorrect placement of the row of caps can be avoided, making it easy to quickly and correctly install the row of caps onto the corresponding bottle body 225, which helps to further improve the water quality testing efficiency of the water quality analyzer.

[0095] In some embodiments, such as Figure 11 and Figure 12 As shown, the bottle cap 226 includes a cap body 2261 and a first ring body 2262. The first ring body 2262 is disposed on the side of the cap body 2261 facing the bottle body 225, and a reagent slot is formed between the first ring body 2262 and the cap body 2261. The bottle body 225 includes a second ring body 2252, which forms the container opening 2251. The first ring body 2262 and the second ring body 2252 are nested together.

[0096] For example, the first ring 2262 is fitted on the outside of the second ring 2252, or the second ring 2252 is fitted on the outside of the first ring 2262, thereby connecting the bottle cap 226 to the bottle body 225.

[0097] In some embodiments, such as Figure 11 and Figure 12 As shown, an annular sealing rib 227 is provided between the first ring body 2262 and the second ring body 2252, and the sealing rib 227 is connected to one of the first ring body 2262 and the second ring body 2252.

[0098] For example, both the first ring body 2262 and the second ring body 2252 are connected to a sealing rib 227. When the first ring body 2262 and the second ring body 2252 are nested together, the sealing rib 227 is sandwiched between the first ring body 2262 and the second ring body 2252, thereby improving the sealing performance between the bottle cap 226 and the bottle body 225.

[0099] In some embodiments, such as Figures 6 to 9 As shown, a limiting plate 2112 is provided in the carrier slot. The limiting plate 2112 is used to limit and cooperate with the test bottle 22 to position the test bottle 22 in the carrier slot.

[0100] For example, such as Figure 6 and Figure 7 As shown, there are two limiting plates 2112. These two limiting plates 2112 respectively cooperate with the detection bottles 22 located at the front and rear sides, limiting the movement of multiple detection bottles 22 in the front-rear direction. In this case, the number of detection bottles 22 must be the same as the number of carrying cavities 2113 to effectively limit the movement of multiple detection bottles 22 using only two limiting plates 2112. For example, as... Figure 8 and Figure 9 As shown, there are seven carrying cavities 2113 and eight limiting plates 2112. Each carrying cavity 2113 has a limiting plate 2112 on both its front and rear sides. The limiting plates 2112 on the front and rear sides of the carrying cavity 2113 limit the movement of the test bottle 22 inside the carrying cavity 2113. In this case, the number of test bottles 22 can be less than the number of carrying cavities 2113, so that different numbers of test bottles 22 can use the same carrying platform 21, improving the versatility of the carrying platform 21.

[0101] By setting a limiting plate 2112 in the carrier slot, the limiting plate 2112 is used to cooperate with the testing bottle 22 to position the testing bottle 22 in the carrier slot, so as to facilitate the limiting of the testing bottle 22 in the carrier slot.

[0102] In some embodiments, the light-blocking plate 2111 can also be used as a limiting plate 2112.

Figure 14 The image shown is a perspective view of the movable base of a water quality tester provided in one embodiment of this utility model. Figure 15 The figure shown is an assembly diagram of the fixed base, movable base, pull rod, sliding sleeve and operating handle of a water quality tester provided in one embodiment of the present invention. Figure 16 The image shown is a perspective view of the mounting base of a water quality tester provided in one embodiment of this utility model. Figure 17 The figure shown is an assembly diagram of a water quality analyzer provided in one embodiment of the present invention, comprising a fixed base, a movable base, a pull rod, a sliding sleeve, an operating handle, a circuit board, a position detection device, a first slotted optocoupler, a second slotted optocoupler, and a third slotted optocoupler. Figure 18 The image shown is an assembly diagram from another perspective of the fixed base, movable base, pull rod, sliding sleeve, operating handle, circuit board, position detection device, first slotted optocoupler, second slotted optocoupler and third slotted optocoupler of a water quality tester provided in one embodiment of the present invention.

[0104] refer to Figures 1 to 5 , Figures 13 to 18 In some embodiments, the water quality analyzer further includes a fixed base 4, a mounting base 5, and a movable base 6. The fixed base 4 and mounting base 5 are both disposed within the housing 1. The fixed base 4 is connected to the housing 1. The mounting base 5 is detachably connected to the fixed base 4 and encloses the detection cavity. The movable base 6 is movably disposed within the detection cavity along a first direction. The light source 31 and the light sensor 32 are both disposed outside the detection cavity and connected to the mounting base 5. The detection carrier 2 is disposed within the detection cavity, and the support platform 21 is connected to the movable base 6. The fixed base 4 has a first guide portion 41, and the movable base 6 has a second guide portion 61. The second guide portion 61 movably engages with the first guide portion 41 along the first direction.

[0105] The fixed base 4 and the housing 1 can be connected by fasteners or by snap-fit ​​or other methods; this invention does not impose specific limitations on this connection. Similarly, the mounting base 5 and the fixed base 4 can be connected by fasteners or by snap-fit ​​or other methods; this invention does not impose specific limitations on this connection. The light source 31 and the light sensor 32 can be connected to the mounting base 5 by fasteners or by snap-fit ​​or other methods; this invention does not impose specific limitations on this connection. The support platform 21 and the movable base 6 can be connected by fasteners or by snap-fit ​​or other methods; this invention does not impose specific limitations on this connection.

[0106] By enclosing the detection cavity with the mounting base 5 and the fixing base 4, and placing the detection carrier 2 inside the detection cavity, the amount of external light entering the detection cavity can be reduced, further improving the accuracy of the water quality analyzer's detection results. By placing both the light source 31 and the light sensor 32 outside the detection cavity, it is convenient to install and fix the light source 31 and the light sensor 32.

[0107] By providing a first guide part 41 on the fixed seat 4 and a second guide part 61 on the movable seat 6, when the carrier platform 21 moves along the first direction, the second guide part 61 cooperates with the first guide part 41 to prevent the movement direction of the carrier platform 21 from deviating, so that the carrier platform 21 moves along the set route, thereby improving the reliability of the water quality tester.

[0108] Optionally, the mounting base 5 and the fixing base 4 can be set to colors with low light transmittance, such as black or dark gray, so that the detection chamber forms a dark chamber, effectively reducing or even preventing external light from entering the detection chamber and affecting the accuracy of the water quality tester's detection results.

[0109] Optionally, the first guide portion 41 is a guide rod, and the second guide portion 61 is a guide hole, with the guide rod inserted into and mating with the guide hole. The guide rod can be a metal rod.

[0110] For example, the guide rod extends in the front-to-back direction, and there are two guide rods and two guide holes. The two guide rods are arranged at intervals in the left-to-right direction, and the two guide holes are respectively matched with the two guide rods.

[0111] like Figure 5 , Figure 15 and Figure 17 As shown, the movable base 6 is equipped with a pull rod 62. One end of the pull rod 62 is connected to the movable base 6, and the other end of the pull rod 62 passes through the support platform 21 and extends out of the outer side of the housing 1. The pull rod 62 can be a metal rod.

[0112] For example, such as Figure 6 and Figure 17As shown, the support platform 21 is provided with a pull rod through hole 216, through which the pull rod 62 passes and is connected. The pull rod 62 is positioned between two guide rods in the left-right direction. The pull rod 62 is used to pull the movable seat 6 and the support platform 21 to move synchronously, and to drive the detection bottle 22, the locking bead, etc. to move synchronously.

[0113] like Figures 1 to 5 , Figure 15 and Figure 17 As shown, the water quality tester includes an operating handle 16, which is connected to the portion of the pull rod 62 that extends out of the housing 1.

[0114] By setting the operating handle 16, the platform 21 can be moved by pushing and pulling the operating handle 16, which facilitates the movement of the test bottle 22 on the platform 21 between the test position 11 and the waiting position 12, which is conducive to further improving the water quality test efficiency of the water quality tester.

[0115] like Figures 1 to 4 , Figure 17 As shown, the water quality tester includes a bushing 15, which is connected to both the fixed base 4 and the housing 1. The pull rod 62 passes through the bushing 15 and is guided by the bushing 15.

[0116] For example, such as Figure 3 As shown, the housing 1 is provided with a detection channel 1013, which communicates with the interior of the housing 1 and allows the detection carrier 2 to enter and exit the housing 1. A portion of the bushing 15 is located within the detection channel 1013 and connected to the housing 1. Figure 13 As shown, the fixed base 4 is provided with a bushing groove 44, and another part of the bushing 15 is located in the bushing groove 44 and connected to the bushing groove 44.

[0117] By incorporating bushing 15, the friction between the pull rod 62 and the fixed base 4 and housing 1 can be reduced, allowing the user to drive the support platform 21 to move with less force, which helps to further improve the water quality testing efficiency of the water quality analyzer. In addition, the bushing 15 can also reduce the noise when the pull rod 62 moves, improving the user experience of the water quality analyzer.

[0118] In some embodiments, such as Figure 13 , Figure 15 , Figure 17 and Figure 18 As shown, the fixed base 4 is provided with multiple slots 42, which are arranged one-to-one with the bearing positions. The movable base 6 is provided with a retaining bead that is movable along a third direction. The detection bottle 22 is located at the detection position 11, and the retaining bead cooperates with the corresponding slot 42. The third direction is perpendicular to the first direction.

[0119] For example, an elastic element is provided between the locking ball and the movable base 6. The elastic element provides a spring force to the locking ball toward the fixed base 4, allowing the locking ball to move in directions toward and away from the fixed base 4. The third direction includes the direction of the locking ball toward the fixed base 4 and the direction away from the fixed base 4.

[0120] During the movement of the movable seat 6, when no test bottle 22 is located at the test position 11, the locking bead is located outside the slot 42 and can move along the first direction with the movable seat 6; when a test bottle 22 is located at the test position 11, the locking bead engages with the corresponding slot 42, and under the elastic force of the elastic element, a part of the locking bead enters the corresponding slot 42, causing the movable seat 6 to jam relative to the fixed seat 4, prompting the user that a test bottle 22 has moved to the test position 11.

[0121] By setting multiple slots 42 on the fixed base 4 and setting movable beads along the third direction on the movable base 6, and when the test bottle 22 is located at the test position 11, the beads cooperate with the corresponding slots 42, making it convenient for users to determine whether the test bottle 22 has moved to the test position 11, which is conducive to further improving the water quality testing efficiency of the water quality tester.

[0122] To make the technical solution of this utility model easier to understand, the technical solution of this utility model is further described below with the example of the third direction being consistent with the up and down direction, wherein the up and down direction is as shown in the figure.

[0123] For example, the retaining bead is movable in the vertical direction. When the retaining bead engages with the retaining slot 42, the retaining bead moves downward so that part of the retaining bead is located inside the retaining slot 42. During the process of the retaining bead moving out of the retaining slot 42, the retaining bead is squeezed by the slot wall of the retaining slot 42, and the retaining bead moves upward and moves out of the retaining slot 42.

[0124] Optionally, the retaining ball is rotatably connected to the movable seat 6, so that when the retaining ball moves with the movable seat 6 in the first direction, the retaining ball can rotate relative to the movable seat 6, so that there is rolling friction between the retaining ball and the fixed seat 4, thereby reducing the frictional resistance between the retaining ball and the fixed seat 4, and making it convenient for the user to drive the movable seat 6 to move relative to the fixed seat 4 in the first direction.

[0125] In some embodiments, such as Figure 2 and Figure 4 As shown, the support platform 21 has a first extreme position and a second extreme position. In the first extreme position, each test bottle 22 corresponds to one of the test position 11 and the waiting position 12. In the second extreme position, at least a portion of the test bottles 22 are located outside the housing 1, and at most one test bottle 22 corresponds to the test position 11. The water quality analyzer also includes a position detection device 7, which is connected to the mounting base 5. When the support platform 21 is in the first extreme position, the position detection device 7 is triggered by the support platform 21.

[0126] For example, such as Figure 2 As shown, in the first extreme position, the detection bottle 22 located at the rear is in detection position 11, and the remaining detection bottles 22 are in waiting position 12. Figure 4 As shown, in the second extreme position, all detection bottles 22 are located outside the housing 1.

[0127] The position detection device 7 can be a limit switch, which is mounted on the mounting base 5. For example... Figures 6 to 9 As shown, the support platform 21 is equipped with a trigger plate 2114. When the support platform 21 moves to the first limit position, the trigger plate 2114 triggers the limit switch, and the user determines that the moving seat 6 has moved to the first limit position.

[0128] When conducting water quality testing, after placing all the test bottles 22 containing the test liquid on the support platform 21, the moving seat 6 is first moved to the first limit position, and then the moving seat 6 is moved to the second limit position, so that all the test bottles 22 on the support platform 21 pass through the test position 11, and the water quality test of the test liquid in each test bottle 22 is completed.

[0129] By setting up the position detection device 7, users can easily determine whether the movable seat 6 is in the first extreme position, which helps to further improve the water quality detection efficiency of the water quality analyzer.

[0130] In some embodiments, such as Figures 6 to 9 , Figures 16 to 18 As shown, the support platform 21 is provided with multiple first detection slots 214, and at least one first detection slot 214 is provided between two adjacent detection bottles 22. The water quality analyzer includes multiple first slot-type optical couplers 81 and at least one second slot-type optical coupler 82. Both the first slot-type optical couplers 81 and the second slot-type optical couplers 82 are arranged on the moving path of the first detection slots 214, and both the first slot-type optical couplers 81 and the second slot-type optical couplers 82 are connected to the mounting base. When the detection bottle 22 is located at the detection position 11, the first slot-type optical coupler 81 is arranged corresponding to one of the first detection slots 214.

[0131] Multiple first-slot optical couplers 81 work together to detect the movement direction of the carrier stage 21. When the detection bottle 22 is located at detection position 11, the first-slot optical couplers 81 are arranged corresponding to one of the first detection slots 214, so that the second-slot optical couplers 82 can be used to detect whether a detection bottle 22 has passed through detection position 11, thereby obtaining the number of detection bottles 22 that have passed through detection position 11. By obtaining the movement direction of the carrier stage 21 and the number of detection bottles 22 that have passed through detection position 11, it is possible to determine which detection bottle 22 is currently located at detection position 11.

[0132] For example, there are seven first detection slots 214 and seven detection bottles 22, with each detection bottle 22 corresponding to one first detection slot 214. There are three first slot-type optocouplers 81, which work together to detect the movement direction of the support platform 21, for example, whether the support platform 21 is moving forward or backward. Whenever a detection bottle 22 is located at detection position 11, a second slot-type optocoupler 82 is positioned corresponding to one of the first detection slots 214, allowing the number of detection bottles 22 passing through detection position 11 to be obtained during the movement of the support platform 21.

[0133] For example, the detection bottle 22 located at the rear is designated as the first detection bottle, the detection bottle 22 adjacent to and located behind the first detection bottle is designated as the second detection bottle, and the detection bottle 22 adjacent to and located behind the second detection bottle is designated as the third detection bottle. When the initial position of the support platform 21 is that the first detection bottle is located at detection position 11, and the support platform 21 moves in a front-to-back direction, the first slotted optocoupler 81 detects that the support platform 21 always moves in a front-to-back direction, and the second slotted optocoupler 82 obtains that three detection bottles 22 have passed through detection position 11, then it can be determined that the third detection bottle is currently located at detection position 11. When the initial position of the carrier platform 21 is that the first detection bottle is located at the detection position 11, the carrier platform 21 first moves in the direction from front to back, and obtains through the second slotted optical coupler 82 that two detection bottles 22 have passed the detection position 11; then, the carrier platform 21 moves in the direction from back to front, and obtains through the second slotted optical coupler 82 that one detection bottle 22 has passed the detection position 11, it can be determined that the first detection bottle is currently located at the detection position 11.

[0134] By setting the first slotted optical coupler 81 and the second slotted optical coupler 82, the moving direction of the support platform 21 and the number of test bottles 22 passing through the detection position 11 can be obtained, which makes it easier to determine which test bottle 22 is currently located at the detection position 11, and helps to further improve the water quality detection efficiency of the water quality analyzer.

[0135] In a specific embodiment, each detection bottle 22 can correspond to one detection item. For example, one of the seven detection bottles 22 is a zeroing detection bottle used for zeroing, and the remaining six detection bottles 22 are, in order, the first, second, third, fourth, fifth, and sixth detection bottles, which correspond to the first, second, third, fourth, fifth, and sixth items, respectively. When the second detection bottle is located at detection position 11, it is determined that the second item is being detected, and the detection unit 3 is used to detect the second item on the second detection bottle.

[0136] In some embodiments, such as Figures 6 to 9 , Figures 16 to 18As shown, the support platform 21 is provided with multiple second detection slots 215, which are arranged at intervals along a first direction. At least a portion of the second detection slots 215 are correspondingly arranged with at least a portion of the detection bottles 22. The water quality analyzer includes at least one third slot-type optical coupler 83, which is disposed on the moving path of the second detection slots 215 and connected to the mounting base. When the detection bottle 22 is located at detection position 11, the third slot-type optical coupler 83 is arranged corresponding to one of the second detection slots 215.

[0137] For example, there are seven second detection slots 215 and seven detection bottles 22. Except for the detection bottle 22 located at the last side, the other two detection bottles 22 are set one-to-one with the six second detection slots 215. The third slot-type optocoupler 83 is used to detect whether there is a detection bottle 22 in the detection position 11. When there is a detection bottle 22 in the detection position 11, the detection data of the detection unit 3 is collected.

[0138] For example, when testing the test liquid in multiple test bottles 22, the support platform 21 can be moved at a constant speed from front to back. When the third slot-type optical coupler 83 detects that a test bottle 22 is located at the test position 11, the detection data of the detection unit 3 is collected, and the detection of the test liquid in multiple test bottles 22 is completed in sequence.

[0139] By setting up a third slot-type optocoupler 83, it is easier to determine when to collect the detection data of the detection unit 3, which is beneficial to further improve the water quality detection efficiency of the water quality analyzer.

[0140] In a specific embodiment, when the third slot-type optical coupler 83 detects that a test bottle 22 is located at the test position 11, the light source 31 and the first light-transmitting hole 212 both correspond to the test bottle 22 located at the test position 11, and the second light-transmitting hole 213 and the light sensor 32 also correspond to the test bottle 22 located at the test position 11. This ensures that the light emitted by the light source 31 can pass through the first light-transmitting hole 212 and illuminate the test bottle 22 located at the test position 11. At the same time, it ensures that the light emitted from the test bottle 22 located at the test position 11 can be emitted through the second light-transmitting hole 213 and onto the light sensor 32, thereby realizing the detection of the water sample to be tested in the test bottle 22 located at the test position 11.

[0141] When the water quality analyzer performs water quality testing, it can utilize the first slot-type optocoupler 81 and the second slot-type optocoupler 82 for detection. Based on the moving direction of the support platform 21 and the number of test bottles 22 passing through the detection position 11, it determines which test bottle 22 is currently located at the detection position 11. When a test bottle 22 is detected at the detection position 11, it pauses for a preset time, and the detection unit 3 detects the liquid at the detection position 11, collecting the detection data. Alternatively, it can use only the third slot-type optocoupler 83 for detection. Based on whether a test bottle 22 is located at the detection position 11, and when a test bottle 22 is located at the detection position 11, it begins collecting the detection data from the detection unit 3, sequentially obtaining the water quality parameters of the liquids in multiple test bottles 22.

[0142] like Figures 16 to 18 As shown, the mounting base 5 is provided with a first clearance groove 51 and a second clearance groove 52. The first clearance groove 51 is used to avoid the first slot type optocoupler 81 and the second slot type optocoupler 82, and the second clearance groove 52 is used to avoid the third slot type optocoupler 83.

[0143] like Figures 16 to 18 As shown, the mounting base 5 is provided with a first mounting part 55 and a second mounting part 56. The light source 31 is fixed on the lamp plate, the lamp plate is connected to the first mounting part 55, and the light sensor 32 is fixed on the sensor plate, the sensor plate is connected to the second mounting part 56.

[0144] like Figure 2 , Figure 4 , Figure 5 , Figure 17 and Figure 18 As shown, the water quality analyzer also includes a circuit board 93, which is connected to the mounting base 5. The light source 31, the light sensor 32, the first slotted optocoupler 81, the second slotted optocoupler 82, and the third slotted optocoupler 83 are all electrically connected to the circuit board 93. Among them, the first slotted optocoupler 81, the second slotted optocoupler 82, and the third slotted optocoupler 83 are fixedly connected to the circuit board 93.

Figure 20 The image shown is a perspective view of the bottom shell of a water quality analyzer provided in one embodiment of this utility model. Figure 21 The image shown is a perspective view of the top cover of a water quality tester provided in one embodiment of this utility model. Figure 22 The image shown is a perspective view of the top cover of a water quality tester provided in one embodiment of this utility model.

[0146] In some embodiments, such as Figures 1 to 5 , Figures 19 to 22As shown, the housing 1 includes an upper cover 101 and a bottom cover 102. The upper cover 101 and the bottom cover 102 are connected and form a mounting cavity. The detection carrier 2, the detection unit 3, the fixed base 4, the mounting base 5, and the movable base 6 are all disposed within the mounting cavity. The detection channel 1013 is disposed on the upper cover 101 and communicates with the mounting cavity.

[0147] like Figure 5 ,like Figures 19 to 22 As shown, the upper cover 101 is provided with an upper connecting hole 1014, and the bottom shell 102 is provided with a lower connecting hole 1024. The first screw 91 is connected to the upper connecting hole 1014 and the lower connecting hole 1024 to realize the connection and fixation between the upper cover 101 and the bottom shell 102.

[0148] like Figure 5 , Figure 13 , Figures 16 to 20 As shown, the bottom shell 102 is provided with a first connecting hole 1023, the fixing seat 4 is provided with a second connecting hole 43, and the mounting seat 5 is provided with a third connecting hole 53. The second screw 92 is connected to the first connecting hole 1023, the second connecting hole 43 and the third connecting hole 53 to realize the connection and fixation of the fixing seat 4, the mounting seat 5 and the bottom shell 102.

[0149] like Figure 16 As shown, the mounting base 5 is provided with a fourth connection hole 54, and the position detection switch is connected to the fourth connection hole 54 through a fastener.

[0150] like Figures 1 to 5 As shown, the water quality analyzer also includes a display screen 13 and buttons 14. The display screen 13 is used to display the test results, and the buttons 14 are used to control the water quality analyzer. Figure 21 and Figure 22 As shown, the upper cover 101 is provided with a display area 1011 and a button area 1012.

[0153] One embodiment of the water quality testing method of this utility model is implemented using the water quality testing instrument of any of the above embodiments, and the water quality testing method includes:

[0154] The water sample to be tested is placed into the test bottle 22 and the test liquid is obtained in the test bottle 22;

[0155] Place the test bottle 22 on the support platform 21, with some of the test bottles 22 located at the test position 11 and the other part of the test bottles 22 located at the waiting position 12;

[0156] The carrier platform 21 is moved along the first direction so that each test bottle 22 passes through the test position 11. When the test bottle 22 is located at the test position 11, the light source 31 emits light to the test bottle 22 located at the test position 11, and the light sensor 32 receives the light passing through the test bottle 22 to obtain the water quality parameters of the test liquid located at the test position 11.

[0157] In some embodiments, the test bottle 22 is located at the test position 11, and the test bottle 22 stays at the test position 11 for a preset time to obtain the water quality parameters of the test liquid located at the test position 11.

[0158] It is understandable that during the movement of the support platform 21, the test bottle 22 is prone to shaking, which causes the test liquid to shake and affects the accuracy of the test results.

[0159] By keeping the test bottle 22 at the test position 11 for a preset time, the test bottle 22 can be kept stably at the test position 11 for the preset time, thereby avoiding the test liquid from shaking when testing the test liquid in the test bottle 22, which helps to improve the accuracy of the test results.

[0160] Of course, in other embodiments, the support platform 21 can also be moved at a constant speed along the first direction, and the water quality parameters of the detection liquid located at the detection position 11 can be obtained by controlling the moving speed of the support platform 21.

[0161] In some embodiments, when a test bottle 22 stays at the test position 11 for less than a preset time, the support platform 21 first moves to a first limit position, and then moves along a first direction so that each test bottle 22 passes through the test position 11. That is, when a test bottle 22 stays at the test position 11 for less than a preset time, the water quality of the test liquid in each test bottle 22 is retested to improve the accuracy of the test results.

[0162] In other embodiments, when a test bottle 22 stays at the test position 11 for less than a preset time, it is also possible to determine which test bottle 22 has stayed for less than the preset time, and move the test bottle 22 to the test position 11, and retest only the test liquid in the test bottle 22.

[0163] Taking a platform with seven bearing positions as an example, and seven test bottles 22 respectively designated as zeroing test bottle, first, second, third, fourth, fifth, and sixth test bottles, with the first, second, third, fourth, fifth, and sixth test bottles corresponding to the first, second, third, fourth, fifth, and sixth items respectively, the water quality testing method of this utility model according to an embodiment is described with reference to the accompanying drawings:

[0164] Hold the handle 2253 of the block and place the block into the container containing the water sample to be tested, so that all seven bottles 225 of the block are filled with the water sample to be tested, and then remove the handle 2253 from the container.

[0165] Remove the aluminum foil covering all seven 226 bottle caps in the same row, so that the reagents in each reagent trough are exposed to the outside.

[0166] Hold the handle 2263 of the row of caps and place the seven caps 226 on the seven bottles 225 respectively. Shake the test bottle 22 to mix the water sample and reagent thoroughly. When capping the caps 226, ensure that the row of caps is correctly placed on the row of blocks according to the block markings 2254 and cap markings 2264. For example, make the arrows on the row of caps and the arrows on the row of blocks point in the same direction. The cap 226 located at the last side can be left empty without reagent, so that the test bottle 22 located at the last side can be used as a zeroing test bottle.

[0167] The test bottles 22 are placed one by one on the support positions of the support platform 21, and the zeroing test bottle is located at the test position 11. The first, second, third, fourth, fifth and sixth test bottles are located at the waiting position 12. At this time, the second slot-type optocoupler 82 detects that a test bottle 22 has passed the test position 11. The water quality analyzer determines that the current zeroing test bottle is located at the test position 11. The detection unit 3 is used to perform zeroing detection on the test liquid in the zeroing test bottle. The position detection switch detects that the stage is located at the first limit position.

[0168] Hold the operating handle 16 and pull the support platform 21 and the moving seat 6 backward. When the first test bottle moves to the test position 11 and the locking bead moves into the locking slot 42 corresponding to the first test bottle, the user feels a jam when pulling, and the support platform 21 and the moving seat 6 stop moving. During this process, the first slot-type optocoupler 81 detects that the moving direction of the support platform 21 is from front to back, and the second slot-type optocoupler 82 detects that two test bottles 22 have passed the test position 11. The water quality analyzer determines that the first test bottle is currently located at the test position 11 based on the detection results of the first slot-type optocoupler 81 and the second slot-type optocoupler 82, and uses the detection unit 3 to perform the first item test on the test liquid in the first test bottle.

[0169] The first test bottle stays at the test position 11 for a preset time (e.g., 1.5s). When the test result for the first item is obtained, the support platform 21 and the moving seat 6 are pulled backward. When the second test bottle moves to the test position 11 and the locking bead moves into the locking slot 42 corresponding to the second test bottle, the user feels a jamming when pulling, and the support platform 21 and the moving seat 6 stop moving. During this process, the first slot-type optocoupler 81 detects that the moving direction of the support platform 21 is from front to back, and the second slot-type optocoupler 82 detects that three test bottles 22 have passed through the test position 11. The water quality analyzer determines that the second test bottle is currently located at the test position 11 based on the detection results of the first slot-type optocoupler 81 and the second slot-type optocoupler 82, and uses the detection unit 3 to perform the second item test on the test liquid in the second test bottle.

[0170] Similar to the method described above, the third, fourth, fifth, and sixth test bottles are moved sequentially to the testing positions by moving the support platform, and the tests for all six items are completed. When the test result for the sixth item is available, the support platform 21 and the moving base 6 are pulled backward until the platform is at its second limit position. At this point, all test bottles 22 are located outside the housing 1, completing the water quality testing for all items.

[0171] Of course, by holding the operating handle 16 and pulling the support platform 21 and the moving seat 6 backward at a uniform speed, the third slot-type optocoupler 83 detects that a test bottle 22 has moved to the test position 11, and then uses the test unit 3 to test the test liquid in the test bottle 22 until the water quality test of all items is completed.

[0172] The support platform 21 of this embodiment is provided with multiple support positions to hold multiple test bottles 22, enabling the water quality analyzer to collect multiple water samples simultaneously for testing multiple items on the water samples. The light source 31 and the light sensor 32 are positioned on opposite sides of the platform, allowing light to propagate in the same direction and enabling the light sensor 32 to better receive light of a specific color passing through the test bottles 22. Multiple slots 42 are provided on the fixed base 4, and locking beads are provided on the movable base 6. The locking beads cooperate with the slots 42 to complete the physical positioning of the platform during the test. For example, when a "click" sound is heard, the platform is stopped from being pulled, and the test results for the corresponding item are waited for before the platform is pulled again until all items are tested. By providing test slots on the platform and corresponding slot-shaped optical couplers, the current position and the test item can be easily determined. Compared with water quality analyzers in related technologies, the water quality analyzer of this invention can test multiple items at once, is simple to use, convenient to operate, provides accurate results, and has a short testing time.

[0173] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications or equivalent substitutions made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
