[0026] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts under the premise that no creative efforts are made, belong to the scope of protection of the present application.

[0027] As shown in Figures 1-7 The utility model discloses a faucet convenient to replace filter core, including casing 1, the handle 2 of rotation installation in casing 1 top and valve element (not draw in the drawing), the casing 1 is provided with water flow channel 11, the valve element is located in water flow channel 11 and is linked with handle 2, because valve element is located in water flow channel 11 and is linked with handle 2, therefore when needing to open faucet and then realize water flow to flow out, handle 2 is forced to change the state of valve element and make the water flow in the bottom of casing 1 can pass through valve element and flow out from the top, and when reverse handle 2 is forced to change the position of valve element again, valve element plays the role of cutting off water flow channel 11 and the water in the bottom of casing 1 cannot flow to the top through valve element, therefore water cannot flow out (this is prior art, not specific elaboration here), still including the installation base 3 of being located in the bottom of casing 1 and being detachably connected with casing 1 through bolt etc., installation base 3 includes connecting sleeve 32, installation sleeve 31 and the installation groove 33 between connecting sleeve 32 and installation sleeve 31 for casing 1 is loaded, filter core 311 is detachably installed in installation sleeve 31 through magnetic attraction, buckling etc., because installation sleeve 31 is loaded with filter core 311, therefore after casing 1 of faucet is inserted into the installation groove 33 between connecting sleeve 32 and installation sleeve 31, the water from the bottom of casing 1 can pass through filter core 311, remove the impurity in fluid and then flow to the top of casing 1 through valve element and flow out, because the liquid in casing 1 is affected by filter core 311 and then flows out for use, and because installation base 3 is detachably connected with casing 1, when needing to take out filter core 311 and clean and replace, installation base 3 in the bottom of casing 1 is detached to directly contact filter core 311 in installation base 3 without disassembling casing 1, valve element and handle 2, and the same reason is replaced with new filter core 311, and then filter core 311 is turned into installation sleeve 31 to complete the fixation of installation base 3 and casing 1, so that filter core 311 is stably located in casing 1, therefore, the installation base 3 detachably installed with casing 1 can more efficiently and smoothly take out and load filter core 311.

[0028] The connecting sleeve 32 comprises a bottom connecting disc 321, the filter core 311 is located in the mounting sleeve 31 and comprises a nano-silver filtering section 3111 and an activated carbon adsorption section 3112, the mounting sleeve 31 is detachably mounted with a filter part 312 above the activated carbon adsorption section 3112, the lower part of the filter part 312 abuts against the upper end surface of the activated carbon adsorption section 3112, and the lower end of the nano-silver filtering section 3111 abuts against the connecting disc 321. 1. Since the filter core 311 comprises the nano-silver filtering section 3111 and the activated carbon adsorption section 3112, water can pass through the nano-silver filtering section 3111 and the activated carbon adsorption section 3112 in sequence during the process of flowing upwards through the bottom of the shell 1, the nano-silver has antibacterial properties, and the activated carbon can effectively remove impurities and odors in water, thereby improving water quality through double filtration; 2. Since the filter part 312 is detachably mounted on the mounting sleeve 31, the water quality can be further improved, and since the bottom of the filter part 312 abuts against the activated carbon adsorption section 3112 and the lower end of the nano-silver filtering section 3111 abuts against the connecting disc 321, the filter part 312 can be installed together with the mounting sleeve 31 to limit the installation position of the filter core 311, thereby further stabilizing the filter core 311 in the mounting sleeve 31.

[0029] The filter part 312 comprises a filter screen 3121 and a positioning plate 3122, the positioning plate 3122 is located above the activated carbon adsorption section 3112 and is fixedly connected with the mounting sleeve 31 by bolts or the like, and the filter screen 3121 is located above the positioning plate 3122 and is detachably connected with the positioning plate 3122 by bolts, buckles or the like. Since the filter screen 3121 and the positioning plate 3122 are detachably connected, when the filter part 312 is installed in the mounting sleeve 31, the filter screen 3121 can be stably connected with the positioning plate 3122 as a whole without separation, but when the filter screen 3121 needs to be cleaned, it can be taken off from the mounting sleeve 31 alone for cleaning.

[0030] The filter screen 3121 is located in the circumferential direction and protrudes downward and is provided with a plurality of connecting plugs 4 made of rubber or other materials that can easily deform. Each connecting plug 4 includes a plug-in section 41 and a limiting section 42. Each plug-in section 41 is inserted into the positioning plate 3122, and each limiting section 42 is located above the positioning plate 3122. The lower end surface of each limiting section 42 abuts against the upper end surface of the positioning plate 3122. The filter screen 3121 includes plug-in grooves 31211 for accommodating each plug-in section 41. The width of each plug-in groove 31211 is greater than the corresponding plug-in section 41 and less than the limiting section 42. Since the width of each limiting section 42 is greater than the corresponding plug-in section 41, when the filter screen 3121 is installed on the positioning plate 3122, the limiting section 42 needs to be forcibly bent upward to pass through the corresponding plug-in groove 31211. At this time, the lower end surface of the limiting section 42 abuts against the upper end surface of the positioning plate 3122, thereby stably connecting the filter screen 3121 and the positioning plate 3122 together. When the filter screen 3121 needs to be removed from the positioning plate 3122, the mounting sleeve 31 is first separated from the shell 1. After the operator contacts the limiting section 42 and deforms it, the limiting section 42 can be forcibly bent downward to pass through the corresponding plug-in groove 31211, so that it can be separated from the positioning plate 3122. Then, the filter screen 3121 can be removed from the positioning plate 3122 for cleaning.

[0031] Preferably, each limiting section 42 is in the shape of a three-prism with a wide lower part and a narrow upper part. Since the upper part of each limiting section 42 is the narrowest, during the assembly of the filter screen 3121 and the positioning plate 3122, the top of each limiting section 42, i.e., the narrowest part, will first enter the plug-in groove 31211. Therefore, the top of each limiting section 42 can smoothly enter the corresponding plug-in groove 31211, thereby enabling each connecting plug 4 to be more efficiently and conveniently aligned with the corresponding plug-in groove 31211, and enabling each connecting plug 4 to be stably inserted into the corresponding plug-in groove 31211. Since the bottom of each limiting section 42, i.e., the widest part, abuts against the upper end surface of the positioning plate 3122, each limiting section 42 can be stably positioned above the positioning plate 3122, thereby enabling the filter screen 3121 to be cooperated with the positioning plate 3122.

[0032] In addition, the shell 1 is provided with a plurality of positioning blocks 12 corresponding to the mounting sleeve 31, which are used to insert the mounting sleeve 31. The mounting sleeve 31 is made of rubber or other materials that can easily deform. Therefore, when the shell 1 is assembled into the mounting groove 33 between the mounting sleeve 31 and the connecting sleeve 32, each positioning block 12 on the shell 1 can enter the mounting sleeve 31, so that the shell 1 cannot be rotated relative to the mounting base 3 after being limited by each positioning block 12, thereby facilitating the fixation of the shell 1 and the mounting base 3.

[0033] Each of the positioning clamping blocks 12 comprises a plurality of clamping block pieces 121 connected in sequence in the up-down direction and a fitting groove 122 between adjacent clamping block pieces 121, and the mounting sleeve 31 is provided with a fitting piece 313 corresponding to each fitting groove 122, so that after the shell 1 is fitted into the mounting groove 33, the fitting piece 313 is located between the adjacent clamping block pieces 121, and the shell 1 cannot move in the up-down direction relative to the mounting base 3 without external force, thereby facilitating the fixing of the shell 1 and the mounting base 3.

[0034] The shell 1 comprises a mounting disc 13 above the connecting sleeve 32, a plurality of insertion holes 131 are arranged on the mounting disc 13 at intervals, and the connecting sleeve 32 is provided with a screw hole 322 corresponding to each insertion hole 131, so that the relative position of the shell 1 and the mounting base 3 can be determined conveniently by the positioning clamping block 12 and the fitting piece 313, and the mounting disc 13 of the shell 1 is located above the connecting sleeve 32, and each insertion hole 131 is located above the corresponding screw hole 322, thereby enabling the insertion of the bolts into the insertion holes 131 and the threaded cooperation with the corresponding screw holes 322 more conveniently and efficiently.

[0035] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
