With socio-economic development, scientific progress, and the improvement of people's living standards, people's requirements for drinking water quality are constantly increasing, and drinking water quality standards are also constantly developing and improving accordingly.

[0003] Currently, water sample collection is an indispensable step in water quality testing. After water sample collection, necessary water filtration facilitates subsequent water sample testing and analysis. Existing water filtration systems can only filter water samples through a single filtration unit, and the filtration units are inconvenient to combine and disassemble. This can easily affect the flexibility of use when filtering water samples, and long-term use is also inconvenient for cleaning, affecting the filtration effect. Therefore, it is necessary to propose a water sample filtration device to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a water sample filtration device, which aims to improve the existing water sample filtration system, which can only complete the filtration operation of water samples through a single filtration unit. Moreover, the filtration unit is inconvenient to combine and disassemble, which can affect the flexibility of use when filtering water samples. Furthermore, it is inconvenient to clean the device after long-term use, which affects the filtration effect.

[0022] Example

[0023] Please see Figures 1-4 This utility model provides a technical solution: a water sample filtration device, including a support structure 100 and a filtration structure 200.

[0024] Please see Figures 1-4 The support structure 100 includes two support rods 110 and a support plate 130. A fixing plate 120 is fixed on each of the two support rods 110. The support plate 130 is fixed between the fixing plates 120. A funnel 131 is fixed through the bottom of the support plate 130. An external threaded tube 132 is fixed on the upper surface of the support plate 130.

[0025] A pad 111 is fixed to the bottom of the support rod 110, and a holding rod 112 is fixed to the upper end of the two support rods 110. The diameter of the pad 111 is larger than the diameter of the support rod 110, and a counterweight is embedded in the bottom of the pad 111, which can increase the overall weight and make the placement more stable.

[0026] Please see Figures 1-4The filter structure 200 includes a filter assembly 210, a filter collector 220, and a flow guide hopper 230. The filter assembly 210 is threaded onto an external threaded pipe 132. The filter collector 220 is installed below the funnel 131. The surface of the flow guide hopper 230 is connected to a fixing member 240 via a connecting plate 231. The fixing member 240 is slidably mounted on two support rods 110.

[0027] The filter assembly 210 includes a first filter cylinder 211, a second filter cylinder 212, and a third filter cylinder 213. The first filter cylinder 211 is threaded onto an externally threaded tube 132, and a first filter unit 2111 is disposed inside the first filter cylinder 211. The second filter cylinder 212 is threaded onto the first filter cylinder 211, and a second filter unit 2121 is disposed inside the second filter cylinder 212. The third filter cylinder 213 is threaded onto the second filter cylinder 212, and a third filter unit 2131 is disposed inside the third filter cylinder 213. A flow guide hopper 230 is fitted onto the upper inner surface of the third filter cylinder 213. The first filter cylinder 211... The lower inner surface is provided with an internal thread that matches the external threaded tube 132. The upper outer surface of the first filter cylinder 211 is provided with an external thread. The second filter cylinder 212 and the third filter cylinder 213 are configured the same as the first filter cylinder 211. The first filter unit 2111, the second filter unit 2121 and the third filter unit 2131 can be different types of filter screens, filter plates, activated carbon adsorption sponges, etc. with different mesh sizes. The filter assembly 210 can facilitate the filtration of water samples. At the same time, the filter cylinders can be combined and used at will, making filtration more flexible and convenient. They are also easier to disassemble, clean and use.

[0028] The filter collection component 220 includes a spring 221 and a support plate 222. The spring 221 is sleeved on two support rods 110. Movable plates 223 are fixed on both sides of the support plate 222. The movable plates 223 are slidably sleeved on the support rods 110. The two ends of the spring 221 are fixed to the fixed plate 120 and the movable plate 223 respectively. A collection bottle 224 is snapped between the funnel 131 and the support plate 222. Here, the elasticity of the spring 221 is used to install the collection bottle 224 at the bottom of the funnel 131. This can improve the airtightness and stability of the collection, reduce the re-falling of external impurities into the collection bottle 224, improve the stability of the collection, and facilitate the fixing of collection bottles 224 of different sizes.

[0029] The fixing component 240 includes a sliding sleeve 241 and a threaded post 243. The sliding sleeve 241 is slidably fitted onto the support rod 110. The connecting plate 231 is fixed to the sliding sleeve 241. A fixing block 242 is fixed to one side of the sliding sleeve 241. The threaded post 243 is threaded through the interior of the fixing block 242. One end of the threaded post 243 passes through the sliding sleeve 241 and is tightly fitted to the support rod 110. The other end of the threaded post 243 is keyed to a knob 244. The fixing block 242 has a threaded hole that matches the threaded post 243. The sliding sleeve 241 has a through hole that matches the threaded post 243. By rotating the threaded post 243 with the knob 244, its end can be tightly fitted to the support rod 110. This facilitates the fixing of the sliding sleeve 241, thereby ensuring that the guide bucket 230 is fitted and sealed to the upper end of the filter cartridge.

[0030] Specifically, the working principle of this water sample filtration device is as follows: During use, the first filter cylinder 211, the second filter cylinder 212, and the third filter cylinder 213 can be arbitrarily combined using threads and then installed on the external threaded pipe 132 according to specific filtration requirements. At this time, the guide bucket 230 is moved up and down so that its bottom is in contact with the top of any one of the first filter cylinder 211, the second filter cylinder 212, or the third filter cylinder 213. Then, by rotating the threaded post 243 using the knob 244, the end of the threaded post 243 is pressed against the surface of the support rod 110, thereby positioning and fixing the guide bucket 230. Then, the collection bottle 224 is secured to the bottom of the funnel 131 and squeezed and fixed using the elasticity of the spring 221. At this time, the water sample is poured into the interior of the guide funnel 230. The water sample will flow downward and pass through the first filter unit 2111, the second filter unit 2121 or the third filter unit 2131 in sequence, and then flow into the collection bottle 224 for collection. In this way, the filter units can be arbitrarily combined during the filtration process, so the filtration operation can be performed according to different water sample conditions, which is beneficial to improve the flexibility of filtration. At the same time, the threaded installation makes it easy to disassemble, which is more convenient for cleaning or replacement after long-term filtration.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
