[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] Such as Figures 1 - 5As shown, the utility model discloses a faucet with a sterilization function, including a handle 1, a shell 2 and a valve core (not shown in the figure), the handle 1 is located at the top of the shell 2 and is linked to the valve core, and a water outlet 21 is arranged on the front side of the shell 2. By turning the handle 1, the valve core can be driven to swing so that the water at the bottom of the shell 2 can flow to the water outlet 21 through the hole on the valve core, and the reverse turning of the handle 1 can seal the hole on the valve core, and the water flow at the bottom of the shell 2 cannot flow to the water outlet 21 through the valve core (this is the prior art and will not be described in detail here). It also includes a sterilization sleeve 3, which is located in the shell 2 and is detachably connected to the shell 2 by means of buckles, bolts, etc., and an upper nano-silver filter 31, a lower nano-silver filter 32 at the bottom, and an adsorption section 33 containing substances such as activated carbon located between the upper nano-silver filter 31 and the lower nano-silver filter 32, and the upper nano-silver filter 31 and the lower nano-silver filter 32 are respectively connected to the sterilization sleeve 3. 3 is detachably connected by bolts, magnetic attraction, etc., and the lower nano-silver filter 32 is detachably connected to the housing 2 by bolts, magnetic attraction, etc. 1. Due to the presence of the upper nano-silver filter 31 and the lower nano-silver filter 32, the water entering from the bottom of the housing 2 will pass through the lower nano-silver filter 32, the adsorption section 33 and the upper nano-silver filter 31 in sequence before flowing to the water outlet 21, and the water can effectively contact with bacteria or other microorganisms in the process of contacting with the nano-silver particles to play a sterilizing role, and at the same time, the impurities in the water can be adsorbed by the adsorption section 33 to improve the purity of the water flowing toward the water outlet 21; 2. Since the sterilization sleeve 3 is located in the housing 2 and is detachably connected to the housing 2, when the adsorption section 33, the upper nano-silver filter 31 and the lower nano-silver filter 32 in the sterilization sleeve 3 need to be cleaned and replaced, the sterilization sleeve 3 is separated from the housing 2, and the upper nano-silver filter 31 and the lower nano-silver filter 32 are removed to clean and replace them.

[0026] Among them, the upper nano-silver filter 31 and the lower nano-silver filter 32 respectively include a plurality of upper nano-silver strips 311 and lower nano-silver strips 321, and each of the upper nano-silver strips 311 is arranged on the upper nano-silver filter 31 at intervals along the front-to-back direction. The upper nano-silver filter 31 includes matching grooves 312 located between adjacent upper nano-silver strips 311, and each of the lower nano-silver strips 321 is located on the lower nano-silver filter 32 and below each matching groove 312. Since each lower nano-silver strip 321 is located below each matching groove 312, and each upper nano-silver strip 311 is located on the left and right sides of each matching groove 312, water entering from the bottom of the shell 2 can fully contact with each upper nano-silver strip 311 and the lower nano-silver strip 321 in the process of flowing through the lower nano-silver filter 32 and the upper nano-silver filter 31, so that the upper nano-silver filter 31 and the lower nano-silver filter 32 can fully exert the antibacterial effect on the water.

[0027] Further, it also includes an upper bolt and a lower bolt (not shown in the figure). The upper bolt is inserted through the upper nano-silver filter screen 31 and is in threaded fit with the top of the sterilization sleeve 3. The lower bolt is inserted through the lower nano-silver filter screen 32 and is in threaded fit with the bottom of the sterilization sleeve 3. Since the upper nano-silver filter screen 31 is fixed to the top of the sterilization sleeve 3 through the upper bolt, and the lower nano-silver filter screen 32 is fixed to the bottom of the sterilization sleeve 3 through the lower bolt, when it is necessary to clean and replace the upper and lower nano-silvers, after separating the sterilization sleeve 3 from the housing 2, rotating the upper thread and the lower bolt can detach the upper nano-silver filter screen 31 and the lower nano-silver filter screen 32 from the sterilization sleeve 3, thus facilitating the cleaning and replacement of the upper nano-silver filter screen 31 and the lower nano-silver filter screen 32.

[0028] Preferably, the lower nano-silver filter screen 32 includes a lower mounting section 322 and a lower working section 323, the upper nano-silver filter screen 31 includes an upper mounting section 313 and an upper working section 314. The upper bolt is inserted through the upper mounting section 313 and is in threaded fit with the sterilization sleeve 3. The lower bolt is inserted through the lower mounting section 322 and is in threaded fit with the sterilization sleeve 3. Each of the upper nano-silver strips 311 is located on the upper working section 314, and each of the lower nano-silver strips 321 is located on the lower working section 323. The inner wall of the top of the adsorption section 33 is circumferentially fitted with the upper working section 314, and the inner wall of the bottom of the adsorption section 33 is circumferentially fitted with the lower working section 323. When assembling the components inside the sterilization sleeve 3, first fix the upper nano-silver filter screen 31 to the sterilization sleeve 3, and then install the adsorption section 33. Since the top of the adsorption section 33 will be circumferentially fitted with the upper working section 314 and the bottom will be circumferentially fitted with the lower working section 323, then install the yet-to-be-installed lower nano-silver filter screen 32. At this time, the inner wall of the lower working section 323 will be inserted into the adsorption section 33. When the fixation of the upper mounting section 313 and the lower mounting section 322 to the sterilization sleeve 3 is completed, at this time, since the upper part of the adsorption section 33 abuts against the upper working section 314 and the lower part abuts against the lower working section 323, the adsorption section 33 can be stably located inside the sterilization sleeve 3 and will not shake during the process of water flow.

[0029] In addition, a number of limiting members 4 made of materials that are prone to deformation, such as rubber, protrude upward from the lower mounting section 322. Each limiting member 4 includes a fixed section 41 at the top and a limiting section 42 at the bottom. The housing 2 is provided with connection grooves 22 corresponding to each limiting section 42. Since the limiting members 4 made of materials prone to deformation protrude from the lower mounting section 322, when the lower mounting section 322 enters the housing 2, the limiting members 4 will forcibly cross over the bottom of the housing 2 and then enter the connection grooves 22. Therefore, without the action of external force, the lower mounting section 322 will not separate downward from the housing 2, realizing the determination of the relative position between the lower mounting section 322 and the housing 2, thus facilitating the installation of the lower bolt.

[0030] Among them, the upper end surface of each limiting section 42 abuts against the housing 2. Since both the upper and lower end surfaces of the limiting section 42 abut against the housing 2, the housing 2 does not provide space for the limiting section 42 to move up and down, so that the lower mounting section 322 can be stably located in the housing 2.

[0031] Preferably, a first magnet 421 is provided at the bottom of the limiting section 42, and a second magnet 23 is provided in each connection groove 22 of the housing 2. Since during the process of the limiting member 4 forcibly crossing over the housing 2 and entering the corresponding connection groove 22, the first magnet 421 at the bottom of the limiting section 42 will be attracted to the second magnet 23 in the housing 2, further improving the stability of the lower mounting section 322 in the housing 2 after the position of the lower mounting section 322 in the housing 2 is determined.

[0032] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
