[0027] Example 2
[0028] When in use, when the filter element is not installed, the ejector spring 127 on the ejector pin 125 presses and seals the water inlet sealing ring 27 of the filter element part 2 and the inner cavity end face of the joint body 121 through elastic force, and the water inlet end seals the water through the sealing ring. When the filter element is installed, the carbon rod cover 23 of the filter element body 21 lifts the ejector pin 125, and the incoming water enters the gap between the carbon rod 25 and the shell of the filter element body 21 from the reversing position of the carbon rod cover 23, and enters the center hole of the carbon rod 25 through the carbon rod 25. The inlet and outlet flange assembly 11 has a C-shaped structure in appearance and an L-shaped structure for the water path. The flange itself The body 111 is installed on both sides of the joint body 121, and the joint body 121 and the flange body 111 are sealed by the flange body sealing ring 115 on the flange body 111. The upper end of the flange body 111 has a hole for installing a welding-free component 116, which is used to install an L-shaped plug 117 for sealing water in and out. The top of the flange body 111 has a group of bosses, each of which has a blind hole for fixing the bracket 132 bolts and the flange body 111. The joint body 121 has a water inlet cavity, which is L-shaped, for water to enter the filtration system. The holes on the vertical and horizontal planes of the water inlet cavity are used to install the ejector pin 125. The ejector pin 125 is installed with an ejector pin seal ring 126. The ejector pin spring 127 is installed on the upper part of the ejector pin 125. The welding-free cover plate 128 is installed on the upper part of the hole by pressure. The welding-free cover plate 128 and the ejector pin 125 pre-compress the ejector pin spring 127. The position of the inner cavity of the welding-free cover plate 128 is fixed. The filter element touches the ejector pin 125 from the lower part of the hole upward. The ejector pin 125 moves upward and the ejector pin spring 127 is compressed until the upper part of the ejector pin 125 contacts the cover plate. At this time, the water channel is opened. When the filter element is disassembled, the ejector pin The spring 127 moves the ejector pin 125 downward, and the ejector pin sealing ring 126 fits with the boss at the bottom of the water inlet cavity to seal the water inlet. There are 4 groups of bosses with blind holes on the joint body 121, which are coaxial with the 4 groups of holes on the flange baffle 122 and the flange bottom cover 123, and are connected by fastening bolts 124. There is a lock buckle installed with the filter element on the flange baffle 122, which is used to lock the filter element when the filter element is installed to prevent the filter element from falling out. The filter element enters the water from the center hole, and the water is introduced into the gap between the carbon rod 25 and the body through the reversing water channel. After passing through the carbon rod 25, the clean water is discharged from the center;
[0029] The filter system has a built-in water channel closing function. When the filter element is installed, the filter element carbon rod cover 23 lifts the ejector pin 125 and the water valve is opened. When the filter element is removed, the filter element carbon rod cover 23 is no longer combined with the ejector pin 125, and the ejector pin 125 pops down. The sealing ring on the ejector pin 125 closes the water channel.
[0030] The filter element and the joint body 121 adopt a snap-on structure, and the center of the filter element is the water inlet hole. The pre-filter water is flushed into the cavity of the carbon rod 25 and the filter shell through the disguised water channel of the carbon rod cover 23. The pre-filter water passes through the carbon rod 25 and enters the center of the carbon rod 25 to become clean water. The clean water discharges the filter element from the annular hole of the carbon rod 25 and enters the joint, and is discharged from the water outlet flange of the joint.
