Description

Technical Field

[0001] The invention relates to the technical field of water purifiers, and in particular to a household water purifier with a filter element that is easy to replace. Background Art

[0002] With the improvement of people's living standards and the deterioration of the environment, drinking water safety is particularly important. Water purifiers have become an important part of solving drinking water safety. Water purifiers are also called water purifiers and water filters. They are water treatment equipment that deeply filters and purifies water according to the requirements for water use. Household water purifiers are equipment that provides safe and clean drinking water for families. They play an increasingly important role in modern family life. Household water purifiers mainly remove impurities, pollutants and harmful substances in water through physical filtration, adsorption, reverse osmosis and other technologies. The filter element is the core component of the water purifier equipment. Its main function is to filter and purify impurities and pollutants in the fluid to provide people with clean and safe water.

[0003] After long-term use, the filter element needs to be replaced regularly according to the service life of the filter element and the usage of the equipment. However, some waste water is often missed when replacing the filter element. If it is not collected uniformly, it will flow everywhere inside the water purifier and will be difficult to clean. Therefore, we have proposed a household water purifier that is easy to replace the filter element. Summary of the invention

[0051] For the second embodiment, please refer to Figure 1-Figure 8 The present invention provides a household water purifier that is easy to replace the filter element: the covering device 9 includes a side sealing square plate 901 and a vertical long plate 902, the side of the side sealing square plate 901 close to the vertical long plate 902 is rotatably connected to a cleaning mechanism 903 through a rotating bolt, the outer side of the vertical long plate 902 is fixedly connected to an arc-shaped baffle 904, the side of the side sealing square plate 901 close to the vertical long plate 902 is fixedly connected to one side of the inclined long plate 701, the side of the side sealing square plate 901 close to the vertical long plate 902 is fixedly connected to one side of the inner inclined curved plate 703, the bottom of the vertical long plate 902 is fixedly connected to the top of the inner inclined curved plate 703, the side of the side sealing square plate 901 close to the arc-shaped baffle 904 is fixedly connected to one side of the vertical long plate 902, and a plurality of vertical long plates 902 are provided, and the plurality of vertical long plates 902 are evenly distributed on the top of the inner inclined curved plate 703;

[0052] The cleaning mechanism 903 includes a threaded long rod 9031, one end of which is fixedly connected to the driving shaft of the motor 9032, an inclined scraper 9033 is sleeved and threadedly connected to the outer side of the threaded long rod 9031, both sides of the inclined scraper 9033 are fixedly connected to hard arc brushes 9034, both sides of the inclined scraper 9033 are fixedly connected to arc baffles 9035, the inner side of the arc baffle 9035 is fixedly connected to an annular sponge pad 9036, the end of the threaded long rod 9031 away from the motor 9032 is rotatably connected to one side of the side sealing square plate 901 through a rotating bolt, and the motor The output end of the machine 9032 is fixedly connected to one side of the side sealing square plate 901. When in use, the side sealing square plates 901 are set on both sides of the inclined long plate 701 to cover and block the inclined long plate 701 and the inner inclined curved plate 703. When replacing the snap-in filter element 5, the subsequent disassembly and snap-in assembly operations can be carried out directly through the arc-shaped baffle 904. By setting a plurality of vertical long plates 902 and arc-shaped baffles 904 to cooperate with the side sealing square plates 901, the area between the snap-in plate 3 and the water collecting device 7 is surrounded and covered. By setting a deformable arc-shaped baffle 904, it is convenient to replace the snap-in filter element 5.

When the inclined long plate 701 moves upward, it drives the clamping filter element 5 at the top to move upward together to be clamped and fixed with the clamping plate 3 at the top to complete the replacement. The clamping and fixing of the clamping filter element 5 by the inclined long plate 701 and the clamping plate 3 facilitates the replacement of the filter element. By setting the top of the inclined long plate 701 as a lower slope, it is convenient to guide the missed wastewater to flow to both sides. By setting inner inclined curved plates 703 on both sides of the inclined long plate 701, the diverted wastewater is uniformly collected. The wastewater diverted to the inner inclined curved plate 703 will flow into the inclined circular groove 706 and overflow from the inclined circular groove 706 into the V-shaped shell 704 connected to the bottom of the inner inclined curved plate 703. By setting multiple A built-in protrusion 707 is used to collect particulate debris in the flowing wastewater. Side sealing square plates 901 are set on both sides of the inclined long plate 701 to cover and seal the inclined long plate 701 and both sides of the inner inclined curved plate 703. When replacing the snap-in filter element 5, the subsequent disassembly and snap-in assembly operations can be carried out directly through the arc-shaped baffle 904. By setting a plurality of vertical long plates 902 and arc-shaped baffles 904 to cooperate with the side sealing square plates 901, the area between the snap-in plate 3 and the water collection device 7 is surrounded and covered.

When the snap-in filter element 5 is not assembled, the motor 9032 is started to drive the threaded long rod 9031 to rotate. When the threaded long rod 9031 rotates, the threaded cooperation belt The inclined scraper 9033 on the inner side of the inner inclined curved plate 703 is moved, and the inclined scraper 9033 scrapes and cleans the surface of the inclined long plate 701 and the inner inclined curved plate 703 when it moves. When the inclined scraper 9033 moves, it drives the hard arc brushes 9034 and the arc baffles 9035 on both sides to move together. The hard arc brushes 9034 are arranged on both sides of the inclined scraper 9033 and are on the same horizontal line as the inclined circular groove 706 on the inner inclined curved plate 703. When the inclined scraper 9033 moves, the hard arc brushes 9034 rub and clean the particulate debris accumulated on the inner wall of the inclined circular groove 706. By arranging arc baffles 9035 on both sides of the inclined scraper 9033, the position of the surface of the threaded long rod 9031 close to the inclined scraper 9033 is blocked.When the arc baffle 9035 moves, it drives the inner annular sponge pad 9036 to move together. When the annular sponge pad 9036 moves, it is in contact with the surface of the threaded long rod 9031 at all times. The moving annular sponge pad 9036 wipes the surface of the threaded long rod 9031 to absorb water.
