DETAILED DESCRIPTION

[0023] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0024] Please refer to Figure 1-Figure 5The utility model proposes a PP cotton filter element for a water purifier, comprising a shell 1, a base 2 is threadedly installed on the bottom of the shell 1, a PP cotton filter element cartridge 3 is arranged on the upper surface of the base 2, a water inlet pipe 4 and a water outlet pipe 5 are connected on the shell 1, a first switch assembly 6 is provided between the water inlet pipe 4 and the shell 1, a second switch assembly 7 is provided between the water outlet pipe 5 and the shell 1, the interior of the shell 1 is fixedly connected to a blocking ring 8, the upper surface of the base 2 is fixedly connected to a mounting seat 9, the mounting seat 9 is threadedly connected to the shell 1, the upper surface of the mounting seat 9 is fixedly connected to a circular cylinder 10, the upper surface of the circular cylinder 10 is fixedly connected to a sealing ring 11, the inner side of the sealing ring 11 is fixedly connected to a support plate 12, a through hole is provided on the circular cylinder 10 and the support plate 12, the PP cotton filter element cartridge 3 is mounted on the upper surface of the support plate 12, the base 2 and the shell 1 are detachable, the PP cotton The filter cartridge 3 is located between the base 2 and the outer shell 1. When the PP cotton filter cartridge 3 needs to be taken out, the base 2 is separated from the outer shell 1. When separated, the first switch assembly 6 and the second switch assembly 7 are closed to prevent unpurified water from entering the outer shell 1. At the same time, the water in the outlet pipe 5 is prevented from flowing back and causing waste. When the base 2 is reinstalled, water enters the outer shell 1 and must pass through the PP cotton filter cartridge 3 from the bottom of the PP cotton filter cartridge 3 through the support plate 12 and the circular cylinder 10 to flow out from the outlet pipe 5 on the side of the outer shell 1. It flows out through the outlet pipe 5 on the side of the outer shell 1. By setting a sealing ring 11, the gap between the PP cotton filter cartridge 3 and the blocking ring 8 is closed to prevent a large amount of water from not passing through the PP cotton filter cartridge 3 for filtration, and directly passing through the blocking ring 8 through the gap between the PP cotton filter cartridge 3 and the blocking ring 8, resulting in a lower filtering effect on water.

[0025] like Figure 2 and Figure 3As shown, the first switch assembly 6 includes a shell 61, which is fixedly connected to the shell 1. A circular through hole is provided on the upper surface of the shell 1. The shell 61 is communicated with the water inlet pipe 4. Two fixing rings 62 are fixedly connected in the shell 61. The inner wall of the shell 61 is fixedly connected to the support plate 63. The support plate 63 is slidably connected to the vertical rod. Both ends of the vertical rod are fixedly connected to the sealing plug 64. The sealing plug 64 is respectively matched with the fixing ring 62. A first spring 65 is fixedly connected between one of the sealing plugs 64 and the support plate 63. The inner side of the fixing ring 62 is an inclined surface, the sealing plug 64 is conical, and the side of the sealing plug 64 is an inclined surface. The upper surface of the support plate 12 is fixedly connected to the vertical rod 13. The vertical rod 13 passes through the PP cotton filter cartridge 3. The upper and lower surfaces of the PP cotton filter cartridge 3 are provided with circular through holes. When the PP cotton filter cartridge 3 is installed, the vertical rod 13 pushes the sealing plug 64 upward to make the two sealing The sealing plugs 64 move up together, opening the fixing ring 62 to allow water to enter the housing 1. When the PP cotton filter cartridge 3 is taken out, the two sealing plugs 64 are gradually reset to block the fixing ring 62 under the action of the first spring 65. The rotation of the base 2 requires a certain process. During this process, the sealing plugs 64 gradually enter the fixing ring 62, but there is still a gap. After some water enters the shell 61 from above, it needs to pass through the two sealing plugs 64 before it can enter the housing 1, extending the time for water to enter the housing 1, reducing the volume of water entering the housing 1 during the process of opening the base 2, and reducing waste, because at this time the sealing ring 11 is already away from the gap between the PP cotton filter cartridge 3 and the blocking ring 8. The water entering the housing 1 during the process of opening the base 2 cannot be strictly filtered, let alone enter the water outlet pipe 5, and will only overflow through the gap between the base 2 and the housing 1, causing waste.

[0026] like Figure 4 As shown, the second switch assembly 7 includes a fixed box 71, which is fixedly connected to the shell 1. The fixed box 71 and the shell 1 are provided with a communicating through groove, the water outlet pipe 5 is communicated with the fixed box 71, the side wall of the shell 1 is slidably connected to the sliding rod 72, one end of the sliding rod 72 is fixedly connected to the baffle 73, and a second spring 74 is fixedly connected between the baffle 73 and the side wall of the shell 1. The mounting seat 9 is conical, one end of the sliding rod 72 is an arc surface, and the lower surface of the base 2 is fixedly connected to the handle 14. When the base 2 is taken out, as the base 2 drops, the second spring 74 pushes the sliding rod 72 to pull the baffle 73 to block the through groove to prevent water from flowing back. When the base 2 is installed, the base 2 pushes the sliding rod 72, and the sliding rod 72 pushes the baffle 73 away from the through groove, and the water outlet pipe 5 is communicated with the shell 1, so that the connection and closing of the water outlet pipe 5 can be controlled more quickly.

[0027] Working principle: When the PP cotton filter cartridge 3 is installed, the vertical rod 13 pushes the sealing plug 64 upward, so that the two sealing plugs 64 move up together, open the fixing ring 62, and allow water to enter the outer shell 1. The base 2 pushes the sliding rod 72 to slide, pushes the baffle 73 to slide, and opens the through groove. Water enters the outer shell 1 and must pass through the PP cotton filter cartridge 3 from the bottom of the PP cotton filter cartridge 3 through the support plate 12 and the circular cylinder 10 to flow out from the water outlet pipe 5 on the side of the outer shell 1. When the PP cotton filter cartridge 3 is taken out, the vertical rod 13 drops, and the two sealing plugs 64 gradually return to their original position under the action of the first spring 65 to block the fixing ring 62. As the base 2 drops, the second spring 74 pushes the sliding rod 72 to pull the baffle 73 to block the through groove to prevent water from flowing back.

[0028] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
