DETAILED DESCRIPTION

[0020] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a household water filtering and purification device, comprising: a shell 1 and a connecting pipe 8, a primary filter element 2 is installed inside the shell 1, one side of the primary filter element 2 is connected to a secondary filter element 3 through a pipeline, the side of the secondary filter element 3 away from the primary filter element 2 is connected to a tertiary filter element 4 through a pipeline, the side of the tertiary filter element 4 away from the secondary filter element 3 is connected to a water storage tank 5 through a pipeline, the side of the water storage tank 5 away from the tertiary filter element 4 is connected to a water outlet pipe 6 penetrating the shell 1, the side of the primary filter element 2 away from the secondary filter element 3 is connected to a water inlet pipe 7 penetrating the shell 1, and the connecting pipe 8 is connected to one side of the water inlet pipe 7.

[0022] A fixed block 9 is installed on the outside of the water inlet pipe 7, and push rods 10 are connected through both sides of the fixed block 9. A telescopic block 11 is connected to one end of the push rod 10. A movable spring 12 is installed between the telescopic block 11 and the groove of the fixed block 9. A wedge block 13 is installed on the side of the telescopic block 11 away from the movable spring 12. A clamping rod 14 that penetrates the fixed block 9 is provided on one side of the wedge block 13. A connecting block 15 is installed on the side of the clamping rod 14 away from the wedge block 13. A sealing rubber ring 24 is installed in the groove of the fixed block 9, and the connecting block 15 is installed on the outside of the connecting pipe 8. Embodiment 2

[0023] On the basis of the first embodiment, in order to quickly connect the connecting pipe 8 with the water inlet pipe 7, the connecting pipe 8 can be inserted into the bottom of the water inlet pipe 7, and the connecting pipe 8 can be squeezed hard so that the clamping rod 14 at the top of the connecting block 15 is inserted into the groove of the fixing block 9. Since the ends of the clamping rod 14 and the wedge block 13 that are close to each other are inclined surfaces, the upward movement of the clamping rod 14 will squeeze the wedge block 13 through the inclined surface, so that the wedge block 13 will shrink into the groove of the fixing block 9 through the cooperation of the telescopic block 11 on one side and the movable spring 12. When the clamping rod 14 moves to one side of the wedge block 13, the wedge block 13 is not squeezed by the clamping rod 14, and then the clamping rod 14 will be reset by the movable spring 12, thereby driving the wedge block 13 from the groove of the fixing block 9. When the connecting pipe 8 is to be removed, it is only necessary to push the push rod 10 so that the push rod 10 pushes the telescopic block 11 to move, and the wedge block 11 is used to shrink the wedge block 13 to one side. At this time, there is no wedge block 13 to limit the push rod 14, so the connecting pipe 8 can be quickly removed.

[0024] A mounting plate 16 is installed on one side of the shell 1, and an insertion rod 17 is installed on one side of the mounting plate 16. A protrusion 18 is installed on one end of the insertion rod 17. A movable block 19 is sleeved on the outer side of the insertion rod 17. A telescopic spring 20 is installed between the movable block 19 and the groove of the shell 1. A pressure rod 21 that passes through the shell 1 is provided on one side of the movable block 19. A slider 22 is installed through the slide groove of the shell 1, and a mounting frame 23 is installed on the top of the slider 22. The first-stage filter element 2, the second-stage filter element 3, the third-stage filter element 4 and the water tank 5 are all installed on the top of the mounting frame 23. Embodiment 3

[0025] On the basis of the second embodiment, in order to realize the rapid replacement and maintenance of the equipment inside the housing 1, the pressure rod 21 on one side of the housing 1 can be squeezed, and one end of the pressure rod 21 is arranged close to the inclined surface of the movable block 19 through the inclined surface. When the pressure rod 21 is squeezed, it will drive the movable block 19 to move to the outside of the housing 1. The movement of the movable block 19 will make the hole in the middle of the movable block 19 and the position of the protrusion 18 at one end of the insertion rod 17 aligned. At this time, there is no limit on the protrusion 18 by the movable block 19, and the insertion rod 17 can be quickly moved out of the groove of the movable block 19, so that the mounting plate 16 can be removed from one side of the housing 1, and then the mounting plate 16 can be removed by the slider 22. The mounting frame 23 is pulled out from the inside of the shell 1. At this time, the parts on the mounting frame 23 can be quickly cleaned, replaced and repaired, so that the user can quickly repair and clean the internal equipment. Conversely, it is only necessary to connect the mounting plate 16 to one side of the shell 1, and insert the plug into the groove of the movable block 19, and then release the pressure rod 21. The movable block 19 is not squeezed by the pressure rod 21 and will be reset by the telescopic spring 20, so that the hole through the middle of the movable block 19 is misaligned with the protrusion 18. The mounting plate 16 can be fixed to one side of the shell 1 through the protrusion 18 and the movable block 19, so as to protect the internal equipment.

[0026] In actual use, when the household water filtering and purification device is in use, the water inlet pipe 7 can be connected to the connecting pipe 8, and the water outlet pipe 6 can be connected to the faucet pipe, and then the water purifier can be started, and the domestic water will flow into the primary filter element 2 through the connecting pipe 8 and the water inlet pipe 7. The primary filter element 2 is made of PP cotton, and the PP cotton can filter the mud and rust in the water. After the filtration is completed, it will flow into the secondary filter element 3 through the pipeline. The secondary filter element 3 is made of activated carbon. Organic impurities can be filtered through the activated carbon. After the filtration is completed, it will flow into the tertiary filter element 4 through the pipeline. The tertiary filter element 4 is an RO anti-permeability membrane filter element. The tertiary filter element 4 can filter harmful substances such as bacteria and viruses, and finally flow into the water tank 5. At this time, turning on the faucet can drain the clean water in the water tank 5 to the faucet, and it flows out through the faucet, thereby obtaining clean water quality, which plays a role in purifying the water quality.

[0027] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
