Detailed Implementation
[0024] 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.
[0025] See Figure 1-Figure 4 This utility model provides two technical solutions:
[0026] First implementation: A microfluidic-based water quality purification detector, comprising a cylindrical body 1, wherein a detection and purification mechanism 2 is disposed inside the cylindrical body 1 for detecting purified tap water, the detection and purification mechanism 2 comprising:
[0027] Purification component 21 is installed inside cylinder 1 for filtering tap water. Purification component 21 includes a partition 213 fixedly installed inside cylinder 1, a filter element 212 movably installed inside cylinder 1, a sealing cover 211 threaded on the top surface of cylinder 1, and a fixing component provided inside cylinder 1 to facilitate fixing the filter element 212.
[0028] The detection component 22 is installed inside the cylinder 1 and is used to detect the purified water.
[0029] The connecting component 23 is located on the right side of the cylinder 1 for switching the water flow direction. The fixing component includes a top ring 216 fixedly installed on the top surface of the filter element 212. A top seat 214 is fixedly installed on the bottom surface of the inner cavity of the sealing cover 211. A top groove 215 is opened on the bottom surface of the top seat 214. A base 219 is fixedly installed on the top surface of the partition plate 213. A bottom groove 218 is opened on the top surface of the base 219, and a sealing gasket is provided on the inner side of the bottom groove 218. A bottom ring 217 is fixedly installed on the bottom surface of the filter element 212, and a sealing gasket is provided on the inner side of the bottom ring 217. The top surface of the top ring 216 is tightly attached to the inside of the top groove 215, and the bottom surface of the bottom ring 217 is tightly attached to the inside of the bottom groove 218. The top groove 215 and the bottom groove 218 can fix the position of the filter element 212 through the top ring 216 and the bottom ring 217.
[0030] The sealing cover 211 facilitates the disassembly and replacement of the filter element 212. During use, rotating the sealing cover 211 moves the top seat 214 so that the top groove 215 moves away from the outside of the top ring 216. Then, the filter element 212 can be taken out from the inside of the cylinder 1 for replacement and cleaning. Then, the new filter element 212 is placed into the inside of the cylinder 1 so that the bottom ring 217 is inserted into the bottom groove 218. Next, the sealing cover 211 is covered and rotated in the opposite direction so that the top ring 216 is inserted into the top groove 215. At this time, the filter element 212 can be fixed for subsequent use, making it easy to disassemble and replace the filter element 212, which is very practical.
[0031] The second embodiment differs from the first embodiment in that: the detection component 22 includes a water quality detector 222 fixedly installed on the bottom surface of the inner cavity of the cylinder 1, and the water quality detector 222 includes detection devices such as a TDS detection probe, a COD value detection probe, and a TOC detection probe. The probes directly contact the water sample to be tested. A purified water outlet pipe 223 is fixedly installed on the bottom surface of the cylinder 1. A ring light 221 and a control switch 224 are fixedly installed on the outside of the cylinder 1. The control switch 224 is used to control the opening and closing of the water quality detector 222, and the ring light 221 is used to display the water quality detection status. The top surface of the water quality detector 222 is fixedly installed on the bottom surface of the partition 213. The top end of the purified water outlet pipe 223 penetrates the bottom surface of the cylinder 1 and is fixedly installed on the bottom surface of the water quality detector 222. The connecting component 23 includes a fixed... A connecting pipe 236 is fixedly installed on the right side of the cylinder 1. An inner pipe 235 is movably installed at the right end of the connecting pipe 236. A valve body 232 is fixedly installed at the right end of the inner pipe 235. A water inlet pipe 231 is threaded on the top surface of the valve body 232. The water inlet pipe 231 is an existing mechanism and will not be described in detail here. A drain pipe 234 is fixedly installed on the bottom surface of the valve body 232. A changeover switch 233 is fixedly installed on the front side of the valve body 232. The top end of the drain pipe 234 penetrates the bottom surface of the valve body 232 and extends into the interior of the valve body 232. The right end of the inner pipe 235 penetrates the left side of the valve body 232 and extends into the interior of the valve body 232. The rear end of the changeover switch 233 penetrates the front side of the valve body 232 and extends into the interior of the inner pipe 235. The right end of the connecting pipe 236 and the left end of the inner pipe 235 are connected by a rotating snap-fit.
[0032] The ring light 221 and water quality detector 222 facilitate the detection of purified water quality. After the tap water is purified, it flows into the water quality detector 222, which then detects the water quality. The water quality is indicated by the change in the color of the light in the water quality detector 222, which helps users evaluate the water purification effect of the device and determine when the filter element 212 can be replaced.
[0033] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.
[0034] In use, the user installs the device on the faucet via the water inlet pipe 231. When water is used, the tap water is turned on and flows through the water inlet pipe 231 into the valve body 232, then out through the drain pipe 234 for use. When water purification is required, the user rotates the selector switch 233 to block the drain pipe 234 and open the inner pipe 235. At this time, the tap water flows from the water inlet pipe 231 into the valve body 232, then through the inner pipe 235 and the connecting pipe 236 into the interior of the cylinder 1. The filter element 212 then purifies the tap water, which then flows into the water quality detector 222 for testing and exits through the purified water outlet pipe 234. 23 flows out, and at the same time, the water quality detector 222 will reflect the water quality through the color change of the ring light 221. When the filter element 212 needs to be replaced, the rotating sealing cover 211 drives the top seat 214 to make the top groove 215 move away from the outside of the top ring 216. Then the filter element 212 can be taken out from the inside of the cylinder 1 for replacement and cleaning. Then the new filter element 212 is put into the inside of the cylinder 1 so that the bottom ring 217 is inserted into the bottom groove 218. Then the sealing cover 211 is covered and rotated in the opposite direction so that the top ring 216 is inserted into the top groove 215. At this time, the filter element 212 can be fixed for subsequent use.
