[0032] Among them, reference Figure 2-Figure 4 The limiting assembly includes: a limiting rod 106 installed at the bottom of the filter element 105, a connecting pipe 107 is provided at the top of the filter element 105, a limiting cylinder 108 is installed near the bottom position inside the water purifier housing 1, a pressure block 109 is provided at the top of the limiting cylinder 108, a socket 110 is opened at the top of the pressure block 109 and is compatible with the limiting rod 106, and a spring a111 is installed between the pressure block 109 and the bottom end of the limiting cylinder 108.

[0033] When the filter element 105 is in use, the cover plate 5 on the outside of the shell cover 2 is opened, the filter element 105 is placed into the water purifier housing 1, and the filter element 105 is held by hand so that the limiting rod 106 at the bottom of the filter element 105 is inserted into the limiting cylinder 108, that is, the limiting rod 106 is inserted into the inside of the insertion hole 110, so that the limiting rod 106 is fixed on the top of the pressing block 109. At this time, the filter element 105 is pressed downward with force, so that the pressing block 109 is pressed by the force to press the spring a111 to move downward in the limiting cylinder 108. After adjusting the height of the filter element 105 to be lowered, the connecting pipe 107 at the top of the filter element 105 is aligned with the pipe joint 104, and the filter element 105 is slowly released to reduce the pressure on the pressing block 109. At this time, after the pressure on the spring a111 is reduced, a rebound force will be formed to push the pressing block 109 and the filter element 105 to move upward, so that the connecting pipe 107 is inserted into the inside of the pipe joint 104, thereby quickly completing the installation of the filter element 105 and the pipe joint 104.

[0034] After the filter element 105 has been used for a period of time and becomes dirty, it is necessary to replace the filter element 105. Grasp the outside of the filter element 105 with both hands and press the filter element 105 downward with force, so that the pressure block 109 is pressed by the force to press the spring a111 and move downward in the limiting cylinder 108, pull the connecting pipe 107 out of the pipe joint 104, and then pull the limiting rod 106 out of the socket 110, so that the limiting rod 106 is separated from the pressure block 109, and then the filter element 105 is quickly replaced, which saves time and effort in the process of replacing the filter element 105, and solves the problem that the threaded connection is prone to rotating in the wrong direction, resulting in a more stable connection.

[0035] Among them, reference Figure 1-Figure 2A water inlet pipe 102 is connected to one side of the outer end of the water pump 101, and the water inlet pipe 102 runs through the outside of the water purifier housing 1, a power supply 4 is installed at the bottom end of the water purifier housing 1, and an electric wire is connected between the power supply 4 and the water pump 101, a power cord 401 is connected to one side of the power supply 4, and a plug 402 is installed at the outer end of the power cord 401.

[0036] When the filter element 105 is installed at the pipe joint 104, the water inlet pipe 102, the water pump 101, the water delivery pipe 103, the pipe joint 104 and the filter element 105 are connected, and the external water pipe is connected to the outer end of the water inlet pipe 102. A faucet is installed at the outer end of the water purifier housing 1 and a control panel is installed on the surface. One end of the water delivery pipe 103 is connected to the faucet, and the control panel is connected to the power supply 4 and the water pump 101 through wires. At this time, the plug 402 at the outer end of the power cord 401 is inserted into the external power supply, so that the water pump 101 and the control panel are powered on, and the control panel is connected to the water pump 101 through the control panel. The board can control the start and stop of the water pump 101. When the water pump 101 is started, water is transported from the external water pipe to the water inlet pipe 102, and then transported to the pipe joint 104 and the filter element 105 through the water pipe 103. The water source is purified by the filter element 105 and then transported from the water pipe 103 to the faucet. The switch valve at the top of the faucet is opened to release the purified water for use. The control program involved in the utility model can be implemented by those skilled in the art according to the same or similar principles in the prior art. This part is not the innovation of the utility model.

[0037] Among them, reference Figure 4 Two sealing rings 112 are sleeved on the outside of the connecting pipe 107 , and the diameter of the two sealing rings 112 is consistent with the inner ring of the pipe joint 104 .

[0038] When the connecting pipe 107 is docked and installed with the pipe joint 104, the connecting pipe 107 is inserted into the pipe joint 104, and the sealing ring 112 sleeved on the outside of the connecting pipe 107 will fit tightly against the inner wall of the pipe joint 104. The sealing ring 112 increases the sealing between the connecting pipe 107 and the pipe joint 104 to prevent water leakage during water transmission and filtration.

[0039] Among them, reference Figure 2 and Figure 4 A support rod 3 is provided on the top of the pipe joint 104, a mounting block 301 is provided on the top of the support rod 3, and screw holes 302 are respectively opened on both sides of the top of the mounting block 301.

[0040] During the use of the pipe joint 104, the mounting block 301 on the top of the support rod 3 is tightly attached to the top of the inner top of the water purifier housing 1 and docked with the mounting screw hole at the top of the inner top of the water purifier housing 1. At this time, the bolt is screwed into the mounting screw hole from the screw hole 302 to fix the mounting block 301 to the top of the inner top of the water purifier housing 1, supporting the placement of the pipe joint 104 to prevent the pipe joint 104 from shaking and being unstable, which facilitates the docking and installation of the pipe joint 104 and the connecting pipe 107.

[0041] Example 2

[0042] Based on Example 1, Figure 5-Figure 9 The disassembly component includes: a cover plate 5 arranged on the outside of the shell cover 2 and rotatably connected by a hinge, a fixing block 501 is provided on one side of the outer end of the cover plate 5, a fixing groove 502 adapted to the fixing block 501 is provided on one side of the inner side of the shell cover 2, a clamping groove 503 is provided inside the fixing block 501, a clamping block 504 is provided inside the fixing groove 502, a movable hole 505 is arranged on the outside of the shell cover 2 and communicates with the fixing groove 502, a pull rod 506 connected to the clamping block 504 is provided inside the movable hole 505, and a spring b507 is sleeved on the pull rod 506, and one end of the spring b507 is connected to the clamping block 504, and the other end is connected to the movable hole 505.

[0043] After the filter element 105 is installed inside the water purifier housing 1, the cover plate 5 is rotated to seal the housing cover 2, and the fixing block 501 at one end of the cover plate 5 enters the fixing groove 502 and fits with the fixing groove 502. The pull rod 506 is grasped and pulled toward the outside of the housing cover 2, and the pull rod 506 moves outward from the movable hole 505, so that the pull rod 506 drives the block 504 to squeeze the spring b507 toward the movable hole 505, so that the block 504 is in the fixing groove 502. Move and adjust the position until the fixed block 501 is completely fitted with the fixed groove 502, then release the pull rod 506. At this time, the squeezing force of the block 504 on the spring b507 disappears, that is, the spring b507 generates a rebound force to push the block 504 to move into the groove 503, so that the block 504 is engaged with the groove 503, and then the fixed block 501 is fixed inside the fixed groove 502, and the cover plate 5 is locked to prevent rotation, thereby shielding and protecting the filter element 105.

[0044] When replacing the filter element 105, grab the pull rod 506 and pull it toward the outside of the shell cover 2. The pull rod 506 moves outward from the movable hole 505, so that the pull rod 506 drives the clamping block 504 to squeeze the spring b507 to compress and fit toward the movable hole 505, allowing the clamping block 504 to move out from the inside of the clamping groove 503, releasing the limit on the fixed block 501, so that the fixed block 501 can be moved out in the fixed groove 502, and then the cover 5 is opened to expose the filter element 105 to the outside, thereby achieving the purpose of convenient and quick replacement of the filter element 105 and solving the problem that the water purifier housing 1 and the shell cover 2 are installed by bolts and disassembled with tools.

[0045] Among them, reference Figure 6 and Fig. 9 An open groove 508 is provided on the outside of the fixed block 501, and the open groove 508 is communicated with the card slot 503. When the fixed block 501 enters the fixed slot 502, the open groove 508 on the outside of the fixed block 501 is set to avoid forming resistance to the card block 504, so that the card block 504 can be flexibly pulled to adjust its position for use.
