[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 9The water purifier filter element shown includes a filter cover assembly 1 and a filter cartridge 2 installed at the bottom of the filter cover assembly 1. The filter cover assembly 1 includes a fixing base 11, on which a first blocking member 111 and a second blocking member 112 are provided. A fixing groove 113 is formed between the first blocking member 111 and the second blocking member 112. A fixing member 21 is provided at the opening of the filter cartridge 2. The fixing member 21 is inserted into the fixing groove 113, so that the first blocking member 111 and the second blocking member 112 are fixed with the fixing member 21 by interference fit. With the structure of this utility model, since the fixing base is provided with a first blocking member and a second blocking member, and the fixing member at the opening of the filter cartridge is fixed with the first blocking member and the second blocking member through an interference fit, when it is necessary to disassemble the filter cartridge, it is only necessary to pull or rotate the filter cartridge to separate it from the filter cover assembly. When it is necessary to install the filter cartridge, it is only necessary to insert the fixing member on the filter cartridge into the fixing groove, so that the first blocking member and the second blocking member are fixed with the fixing member through an interference fit, making disassembly and assembly more convenient and facilitating the replacement of filter media by operators.

[0031] Furthermore, to ensure more stable filter cartridge fixing, the radius of the outer wall of the first blocking member 111 is larger than the radius of the inner wall of the fixing member 21, and the radius of the inner wall of the second blocking member 112 is smaller than the radius of the outer wall of the fixing member 21. The outer wall of the first blocking member 111 is inclined, and the inner wall of the fixing member 21 is also inclined, with the outer wall of the first blocking member 111 fitting against the inner wall of the fixing member 21. The outer wall of the second blocking member 112 is divided into an upper and a lower part, with the upper part inclined and the lower part parallel to the outer wall of the fixing member 21. This allows the fixing member 21 to be more accurately inserted into the fixing groove 113 when installing the filter cartridge 2. The greater friction and better fixing effect are achieved when the inclined outer wall of the first blocking member 111 fits against the inclined inner wall of the fixing member 21. After the fixing member 21 is inserted into the fixing groove 113, the outer wall of the first blocking member 111 is fixed with an interference fit against the inner wall of the fixing member 21, and the lower part of the inner wall of the second blocking member 112 is fixed with an interference fit against the outer wall of the fixing member 21.

[0032] As a specific implementation and not a limitation, the filter cover assembly 1 is provided with a water channel group 5, and the filter cover assembly 1 includes a filter cover connector 12, and the filter cover connector 12 is provided with a pipeline group 122 that is connected to the water channel group 5.

[0033] Preferably, in order to achieve the function of water purification, the water circuit group 5 includes a first water circuit channel 51 and a second water circuit channel 52, and the pipeline group 122 includes a first water outlet pipe 1221, a second water outlet pipe 1222 and a third water outlet pipe 1223. The first water outlet pipe 1221 is connected to the first water circuit channel 51, the second water outlet pipe 1222 is connected to the second water circuit channel 52, and the third water outlet pipe 1223 is connected to the first water circuit channel 51. The pipeline group 122 is also provided with a water inlet pipe 1224 connected to the water source, and the water inlet pipe 1224 is connected to the second water circuit channel 52. When purified water is needed, the water flows through the inlet pipe 1224 into the second water channel 52, and then flows to the filter media in the filter cartridge. After the water is filtered and purified by the filter media, pure water is output. The pure water is then output through the first outlet pipe 1221, the second outlet pipe 1222 and the third outlet pipe 1223, so that the user can consume purer water. Furthermore, in this application, one inlet pipe and three outlet pipes are provided. The three outlet pipes can meet the user's water needs to the greatest extent.

[0034] As a specific implementation and not a limitation, in order to form a connecting first water passage 51, the filter cover assembly 1 further includes a filter media fixing bracket 14. The filter cover connector 12 is provided with a first inner sleeve 121. The fixing base 11 is provided with a second inner sleeve 114 inserted into the first inner sleeve 121. The filter media fixing bracket 14 is provided with a third inner sleeve 141, which is inserted into the end of the second inner sleeve 114 away from the first inner sleeve 121. The third inner sleeve 141 is in communication with the filter cartridge 2. The first inner sleeve 121, the second inner sleeve 114, and the third inner sleeve 141 together form the first water passage 51. A rubber ring is fitted on the side wall of the second inner sleeve 114. This rubber ring can be made of rubber, latex, silicone, etc. The second inner sleeve 114 is inserted into the first inner sleeve 121, so that the rubber ring fits with the inner wall of the first inner sleeve 121, and the rubber ring can play a good sealing role. A rubber ring is also fitted on the third inner sleeve 141, which is also used to seal the seal.

[0035] Furthermore, in order to form the second water channel 52 and separate the first water channel 51 from the second water channel, the filter cover connector 12 is provided with a water channel gap 123, and the fixing base 11 is provided with a water inlet 115 that connects the water channel gap 123 to the filter cylinder 2. The water channel gap 123 and the water inlet 115 together form the second water channel 52. The water inlet 115 is set on the fixing base 11 and is arranged circumferentially along the outer periphery of the second inner sleeve 114. The water inlet 115 is connected to the filter cylinder 2. After the water enters the water channel gap 123, it will flow through the water inlet 115 to the filter material in the filter cylinder 2, forming the second water channel 52. The second water channel 52 is not connected to the first water channel 51, but is independent. Therefore, the inflow and outflow of water in the second water channel 52 is not affected by the first water channel 51.

[0036] As a specific implementation and not a limitation, in order to detect the working status of the water purifier filter element, a pressure sensor 3 is included. The filter cover connector 12 is provided with an installation channel 124, which is connected to the water circuit group 5. The pressure sensor 3 is inserted into the installation channel 124. The installation channel 124 can be connected to the first water circuit channel 51 or the second water circuit channel 52. When the pressure sensor 3 detects that the water pressure is too low, it indicates that the water purifier filter element is blocked. At this time, the water purifier filter element will issue an alarm to remind the user that the water purifier filter element has malfunctioned. The user can quickly deal with the malfunction to avoid further damage to the water purifier filter element and potential safety hazards.

[0037] Furthermore, to facilitate the rapid installation and removal of the pressure sensor 3, a fixing frame 6 is provided at the open end of the mounting channel 124. A pin 31 is inserted into the fixing frame 6, and the pin 31 cooperates with the pressure sensor 3 to fix the pressure sensor 3 to the mounting channel 124. Because the fixing frame 6 is provided at the open end of the mounting channel, and the pin 31 is inserted into the fixing frame 6, the pin 31 is properly engaged with the pressure sensor 3, preventing the pressure sensor 3 from detaching from the mounting channel 124. When it is necessary to disassemble the pressure sensor 3, simply pull out the pin 31 to remove the pressure sensor 3; disassembly is very convenient.

[0038] As a specific embodiment and not a limitation, to facilitate the disassembly of the fixing seat 11, the filter cover connector 12 is provided with a fixing ring 13, the fixing ring 13 is provided with an installation port 132, and the fixing seat 11 cooperates with the installation port 132 to detachably fix the fixing seat 11. The fixing seat 11 is provided with a first snap-fit ​​block 116, and the inner wall of the installation port 132 is provided with a second snap-fit ​​block 131. The first snap-fit ​​block 116 and the second snap-fit ​​block 131 cooperate to snap the fixing seat 11 onto the fixing ring 13. The retaining ring 13 is fixed to the filter cover connector 12 by a threaded connection. Since the inner wall of the mounting port 132 is provided with a second snap-fit ​​block 131 and the fixing seat 11 is provided with a first snap-fit ​​block 116, when the fixing seat 11 needs to be installed, the first snap-fit ​​block 116 abuts against the second snap-fit ​​block 131 and the fixing seat 11 is rotated to fix the fixing seat 11 to the retaining ring 13. When the fixing seat 11 needs to be disassembled, the fixing seat 11 is simply rotated to disengage the first snap-fit ​​block 116 from the second snap-fit ​​block 131 to disassemble the fixing seat 11.

[0039] Furthermore, in order to protect the filter cover assembly 1 from external influences, a housing 4 is also included, and the filter cover assembly 1 is installed inside the housing 4.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
