[0029] Example

[0030] Reference Figure 1-6 As shown, a domestic water purification device includes a purifier housing 1. An inlet pipe 211 is installed at the top of the purifier housing 1, and a first mounting plate 220 is connected to the bottom of the housing via a locking mechanism. An outlet pipe 212 is installed at the bottom of the first mounting plate 220. A sealing ring 213 is fixed to the outer wall of both the inlet and outlet pipes 211 and 212. The sealing ring 213 provides a sealing effect, ensuring the stability of the connection between the inlet and outlet pipes and preventing leakage of domestic water. A first fixing plate 216 is fixed to the inner wall of the purifier housing 1, and an inner cylinder 214 corresponding to the first mounting plate 220 is fixed to the outer wall of the first fixing plate 216. Domestic water enters through the inlet pipe 211, is purified through the inner cylinder 214, and is then discharged through the outlet pipe 212, achieving a good purification effect.

[0031] The locking mechanism includes a sealing gasket 221, a fixing block 225, a slot 226, a connecting plate 227, a second fixing plate 228, a locking block 229, and a pushing component. The outer wall of the first mounting plate 220 is fixed with a sealing gasket 221 that fits against the inner wall of the purifier housing 1. The sealing gasket 221 can be made of rubber to achieve good sealing performance. A fixing block 225 is fixed to the bottom of the purifier housing 1. A slot 226 is opened inside the fixing block 225. A connecting plate 227 is fixed to the bottom of the first mounting plate 220. A second fixing plate 228 is fixed to the outer wall of the connecting plate 227. A locking block 229 corresponding to the slot 226 is sleeved on the outer wall of the second fixing plate 228. The outer wall of the locking block 229 is connected to the connecting plate 227 through a pushing component. The pushing component can drive the locking block 229 to slide along the outer wall of the second fixing plate 228. The second fixing plate 228 can move in and out of the slot 226, so that the first mounting plate 220 and the purifier housing 1 can be quickly disassembled and assembled, which is convenient for staff to quickly clean the inside of the inner cylinder 214.

[0032] The driving component includes a movable plate 230, a second mounting plate 231, a threaded rod 232, a threaded sleeve 233, and a rotating plate 234. The movable plate 230 is fixed to the outer wall of the locking block 229. A second mounting plate 231, corresponding to the movable plate 230, is fixed to the outer wall of the connecting plate 227. A threaded sleeve 233 is fixed inside the second mounting plate 231. A threaded rod 232, rotatably connected to the movable plate 230, is threaded onto the inner wall of the threaded sleeve 233. A rotating plate 234 is fixed to the end of the threaded rod 232 furthest from the movable plate 230. Rotating the rotating plate 234 causes the threaded rod 232 to rotate, which, under the action of the thread, drives the movable plate 230 and the locking block 229 to move vertically back and forth, achieving the driving purpose. Several sets of anti-slip grooves 235 are provided on the outer wall of the rotating plate 234, arranged circumferentially. These anti-slip grooves provide excellent anti-slip effect, enhancing the comfort of the operator.

[0033] A pad 222 is fixed to the inner wall of the bottom end of the purifier housing 1, which fits against the first mounting plate 220. The pad 222 can support and position the first mounting plate 220. A positioning block 223 is fixed to the outer wall of the first mounting plate 220, and a positioning groove 224 corresponding to the positioning block 223 is opened on the outer wall of the inner cylinder 214. The positioning block 223 and the positioning groove 224 can achieve further positioning, so that the first mounting plate 220 can be pre-positioned with the inner cylinder 214, which facilitates the assembly and disassembly of the first mounting plate 220.

[0034] A filter plate 215 corresponding to the liquid inlet pipe 211 is fixed on the inner wall of the top of the inner cylinder 214. The inner cylinder 214 is provided with a first filter layer 217, a second filter layer 218 and a third filter layer 219 from top to bottom. The first filter layer 217 is filled with PP cotton, the second filter layer 218 is filled with granular activated carbon, and the third filter layer 219 is filled with high-precision compressed activated carbon to achieve the purpose of fine purification.

[0035] The top of the purifier housing 1 has a cleaning port 316 corresponding to the filter plate 215. A closing plate 314 is rotatably connected to the top of the purifier housing 1 for opening or closing the cleaning port 316. Opening the cleaning port 316 makes it easier for staff to clean the clogged filter holes inside the filter plate 215. Specifically, tools such as a drain cleaner can be inserted into the purifier housing 1 through the cleaning port 316 to clear the filter holes and further improve the thoroughness of cleaning. A rotating plate 313 is fixed to the outer wall of the closing plate 314. A support frame 311 is fixed to the top of the purifier housing 1. The bottom of the support frame 311 is rotatably connected to the rotating plate 313 through a rotating column 312. A pulling column 317 is fixed to the top of the closing plate 314. This arrangement provides good stability, and the closing plate 314 can be rotated on the top of the purifier housing 1 by the rotating plate 313. A torsion spring 315 is wound around the outer wall of the rotating column 312. One end of the torsion spring 315 is attached to the support frame 311 and the other end is attached to the rotating plate 313. The torsion spring 315 can play a good rebound purpose, ensuring that the closing plate 314 can rebound in the initial position and close the cleaning port 316 to prevent water from overflowing.

[0036] Working principle: When the inside of the inner cylinder 214 needs to be cleaned, the rotating plate 234 drives the threaded rod 232 to rotate. Under the action of the thread, the movable plate 230 and the locking block 229 can be moved. The locking block 229 slides along the outer wall of the second fixed plate 228 and drives the locking block 229 to disengage from the locking groove 226. At this time, the first mounting plate 220 can be pulled outward. At this time, the positioning block 223 will disengage from the positioning groove 224. The staff can quickly clean the bottom of the inner cylinder 214 and replace the first filter layer 217, the second filter layer 218 and the third filter layer 219.

[0037] Subsequently, pulling the pull column 317 causes the closing plate 314 and the rotating plate 313 to rotate, and also causes the rotating column 312 to rotate, causing the torsion spring 315 to be twisted and compressed. The staff can clean the holes in the filter plate 215 through the cleaning port 316 to achieve a comprehensive cleaning purpose. When the pull column 317 is released, the closing plate 314 and the rotating plate 313 are reset under the rebound action of the torsion spring 315. The closing plate 314 closes the cleaning port 316 to prevent domestic water from overflowing.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
