In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description merely illustrates a preferred embodiment of the utility model and that the utility model may be practiced without one or more of these details. In other instances, well known features have not been described in detail so as not to obscure the utility model.
The present invention provides a faucet water purifier, as shown in fig. 1, which may include a filter cartridge assembly 100 and a waterway switching assembly 200. As shown in fig. 2 to 3, the filter cartridge assembly 100 may have a purified water inlet passage 110, a raw water inlet passage 120, a mounting chamber 130, and an outlet passage 140. The raw water inlet passage 120 may communicate with the water outlet passage 140 through the installation cavity 130. The clean water inlet passage 110 may communicate with the water outlet passage 140 through the installation cavity 130. After entering the filter element assembly 100, raw water can flow out from the water outlet 140 through the raw water inlet 120 without being filtered. After entering the filter element assembly 100, the raw water may pass through the water inlet channel and the water outlet channel 140, and then be filtered to flow out.
The mounting cavity 130 may have a mounting opening 131 communicating with the outside. The mounting opening 131 may be formed in the outer peripheral wall of the cartridge assembly 100. As shown in fig. 4 to 5, the waterway switching assembly 200 may include a switching body 210 and an operating member 220 connected to each other. The switching body 210 may be sealingly disposed within the mounting cavity 130. The operating member 220 may protrude out of the mounting opening 131 via the mounting opening 131. The user can control the switching body 210 through the operating member 220 protruding out of the mounting opening 131. The switching body 210 may be provided with a purified water intermediate passage 211 and a raw water intermediate passage 212. The switching body 210 is switchable between a first position and a second position by the operation member 220. The switching means may include translation, rotation and other switching means.
The purified water intermediate passage 211 can be communicated between the purified water inlet passage 110 and the water outlet passage 140 when the switching body 210 is at the first position. The raw water intermediate passage 212 may communicate between the raw water inlet passage 120 and the outlet passage 140 when the switching body 210 is in the second position. That is, when the switching body 210 is in the first position, the water in the filter element assembly 100 can flow through the clean water inlet channel 110, the clean water intermediate channel 211 and flow out of the water outlet channel 140. When the switching body 210 is in the second position, the water in the filter cartridge assembly 100 may pass through the raw water inlet passage 120, the raw water intermediate passage 212, and flow out of the water outlet passage 140.
The purified water intermediate passage 211 and the raw water intermediate passage 212 may be different passages provided on the switching body 210, and the purified water intermediate passage 211 and the raw water intermediate passage 212 may be moved by changing the position of the switching body 210 to be communicated with each other. The purified water intermediate passage 211 and the raw water intermediate passage 212 may be provided as the same passage, and the position of the passage is changed to communicate the water outlet passage 140 with the purified water inlet passage 110 or the raw water inlet passage 120, respectively.
The operation member 220 can move the switching body 210 in various ways. The operating member 220 may be directly connected to the switching body 210, and a user may directly change the position of the switching body 210 through the operating member 220, such as rotation and translation. The operating member 220 may also be indirectly connected to the switching body 210, for example by providing an electromagnet, using magnetic forces to change the position of the switching body 210.
Therefore, the faucet water purifier with the installation structure is provided with the installation cavity 130 in the filter element assembly 100, and the function of water path switching can be realized by controlling the switching main body arranged in the installation cavity 130 so as to meet different water requirements of users. Furthermore, by hermetically disposing the switching body 210 in the mounting cavity 130, water leakage from the assembly gap between the switching body 210 and the mounting cavity 130 can be reduced, thereby reducing the risk of water leakage from the faucet water purifier. Meanwhile, the water path switching assembly has few parts, so the faucet water purifier is relatively simple to assemble and low in product cost.
Illustratively, the switching body 210 may include at least one rotation shaft. The purified water intermediate passage 211 and the raw water intermediate passage 212 may be respectively disposed on the same rotation shaft or different rotation shafts in a manner of radially penetrating the rotation shafts. It should be noted that the rotating shaft may be disposed on the switching body 210. At least one of the shafts is rotatable about its own axis between a first position and a second position by the operating member 220. In one embodiment, the switching body 210 may be a rotating shaft, and the purified water intermediate passage 211 and the raw water intermediate passage 212 may be respectively disposed in different circumferential directions of the rotating shaft. The rotation shaft rotates, and the purified water intermediate passage 211 and the raw water intermediate passage 212 rotate together with the rotation shaft. In another embodiment, the switching body 210 may be two rotating shafts, which are coaxially or non-coaxially disposed, and do not interfere with each other when they rotate, and the water purification intermediate channel 211 and the raw water intermediate channel 212 may be disposed on the two rotating shafts, respectively.
In both embodiments, the user can control the rotation of the rotating shaft between the first position and the second position through the operating member 220. It is understood that the number of the rotation shafts is not limited to one or two, and the number of the purified water intermediate passage 211 and the raw water intermediate passage 212 may be set according to the actual situation.
The water path switching assembly 200 with the arrangement is simple in structure, and only the rotating shaft needs to be inserted into the installation cavity 130 for fixing, so that the installation is convenient, and the implementation is easy.
For example, the purified water intermediate passage 211 and the raw water intermediate passage 212 may be provided on the same rotation shaft. The axis of the rotating shaft can pass through a purified water outlet of the purified water inlet channel (namely a water outlet of the purified water inlet channel in butt joint with the purified water intermediate channel) and a raw water outlet of the raw water inlet channel (namely a water outlet of the raw water inlet channel in butt joint with the raw water intermediate channel). The purified water intermediate passage 211 and the raw water intermediate passage 212 may penetrate the rotation shaft from different radial directions of the rotation shaft and be spaced apart from each other in an axial direction of the rotation shaft.
In the embodiment shown in fig. 2 to 5, a pure water intermediate passage 211 may be provided in the middle of the rotation shaft, and a raw water intermediate passage 212 may be provided on each of both sides of the pure water intermediate passage 211 in the axial direction of the rotation shaft. The radial directions of the two raw water intermediate channels 212 may be the same, and the pure water intermediate channel 211 and the raw water intermediate channel 212 penetrate through the rotating shaft from different radial directions of the rotating shaft, for example, the radial direction of the rotating shaft corresponding to the pure water intermediate channel 211 forms an angle of 90 degrees with the radial direction of the rotating shaft corresponding to the raw water intermediate channel 212. Therefore, every time the rotating shaft rotates 90 degrees, the switching between different waterway channels can be realized.
Of course, in an embodiment not shown, the number of the pure water intermediate passages 211 and the raw water intermediate passages 212 is not limited to the above embodiment, and the included angle between the pure water intermediate passages 211 and the raw water intermediate passages 212 in different radial directions of the rotating shaft may be in other degrees, and those skilled in the art can reasonably select the included angle according to the actual use situation.
As can be seen from this, with this arrangement, the effect of switching the water path can be achieved by rotating the same rotating shaft 213 at different angles.
Illustratively, the mounting cavity 130 may be cylindrical in shape extending in a predetermined radial direction of the filter element assembly 100. That is, the extension direction of the mounting cavity 130 is uniform along the predetermined radial direction of the filter element assembly 100. The switching body 210 may be rotatable about a predetermined radial direction. The mounting openings 131 may be provided at the sides of the filter cartridge assembly 100. That is, the switching body 210 can be installed into the installation cavity 130 from the side of the filter cartridge assembly 100 through the installation opening 131. The switching body 210 is rotatable within the mounting cavity 130. Compared with the switching main body 210 which can translate in the installation cavity 130, the switching main body 210 rotates in the installation cavity 130, so that the moving range of the switching main body 210 can be reduced, the space required by the faucet water purifier in use is reduced, and the faucet water purifier is more convenient for users to use and install.
Illustratively, the mounting cavity 130 may also have a closed end 132 opposite the mounting opening 131 in a predetermined radial direction. Wherein a first seal 310 may be sandwiched between an outer circumferential side wall of the switching body 210 and an inner circumferential side wall of the mounting cavity 130 at the mounting opening 131. At the closed end 132, a second seal 320 is sandwiched between the outer circumferential side wall of the switching body 210 and the inner circumferential side wall of the mounting chamber 130. And the pure water intermediate passage 211 and the raw water intermediate passage 212 are located between the first seal 310 and the second seal 320 in the axial direction of the switching body 210. The first seal 310 and the second seal 320 may comprise any of the seals that are currently available and that may come into existence in the future. The first seal 310 and the second seal 320 may comprise either elastomeric or non-elastomeric members. The elastic member may be clamped between the switching body 210 and the mounting cavity 130 by self-deformation, such as a rubber ring. The non-elastic element may then achieve a sealing effect by controlling the roughness of the contact surfaces, such as ceramic rings or the like.
By arranging the first sealing member 310 and the second sealing member 320, it is ensured that water is prevented from flowing out from a gap between the switching body 210 and the installation cavity 130 to cause a water leakage phenomenon in the process that the switching body 210 moves in the installation cavity 130.
Illustratively, at the mounting opening 131, a first groove 214 disposed around the switching body 210 may be disposed on an outer circumferential sidewall of the switching body 210 and/or an inner circumferential sidewall of the mounting cavity 130. The first seal 310 may snap into the first groove 214. At the closed end 132, a second groove 215 disposed around the switching body 210 may be disposed on an outer circumferential sidewall of the switching body 210 and/or an inner circumferential sidewall of the mounting cavity 130. The second seal 320 may snap into the second groove 215. The first groove 214 and the second groove 215 are configured to fix the first sealing member 310 and the second sealing member 320 on the switching body 210, and limit the axial direction of the switching body 210, so as to prevent water leakage caused by leakage from the switching body 210 during use.
Illustratively, the filter element assembly 100 may be provided with a stopper. The waterway switching assembly 200 may be provided with a limit adapter. The spacing portion and the spacing adaptation portion may cooperate to define the position of the switching body 210 in its axial direction relative to the filter element assembly 100. That is, in the embodiment shown in fig. 2-3, the engagement of the position-limiting portion and the position-limiting engagement portion can prevent the switching body 210 from falling out of the mounting opening 131. The limiting part and the limiting matching part can be directly connected or indirectly connected. In some embodiments, the limiting part may be an end cap disposed at the mounting opening 131, and the limiting fitting part is an end of the switching body 210 near the mounting opening 131. The end cap blocks the mounting opening 131 to prevent the switching body 210 from falling off. In other embodiments, the position-limiting part may also be a magnet, and the position-limiting matching part is a magnetic member of the switching body 210 near the closed end 132, so that the switching body 210 can be prevented from falling out of the mounting cavity 130 by an attractive force between the magnet and the magnetic member.
It is of course to be understood that the position limiting portion and the position limiting engagement portion are not limited to the above two embodiments, and a preferred embodiment will be described in detail below.
Illustratively, the stopper may include a cartridge 400. The cartridge 400 may be disposed on the filter cartridge assembly 100.

Of course, it is understood that the shape of the cartridge 400 is not limited to the U shape, but may be a V shape, a half moon shape, or the like.
Through this setting, spacing portion and spacing adaptation portion's simple structure easily realize. The card socket 400 may not affect the rotation of the switching body 210 while limiting the switching body 210.
Illustratively, the outlet passage 140 may include a purified water outlet passage 141 and a raw water outlet passage 142.

When the switching body 210 is in the second position, the raw water intermediate passage 212 communicates the raw water inlet passage 120 and the raw water outlet passage 142. Of course, the switching manner of the switching body 210 between the first position and the second position may include rotation, translation and other switching manners.
Illustratively, the cartridge assembly 100 may include a body 150, a cap 160, and a cartridge 170. One end of the bottle cap 160 may be connected to the body 150 and form a receiving cavity surrounding the body 150. A filter element 170 may be disposed in the receiving chamber and separate the purified water inlet passage 110 and the raw water inlet passage 120. Thus, the pollution of raw water to purified water can be avoided. The filter element 170 may include various types of filter elements known in the art or that may come into existence in the future, such as a carbon fiber filter element, a PP filter element, a ceramic filter element, or a composite filter element formed by combining a plurality of filter elements. The mounting chamber 130 and the outlet passage 140 may be provided on the bottle cap 160. Waterway switch assembly 200 may be connected to bottle cap 160.

Referring to fig. 4 to 5, grooves may be respectively provided around the water inlets of the purified water intermediate passage 211 and the raw water intermediate passage 212, and the first gasket 510 and the second gasket 520 are respectively inserted into the grooves. The first and second gaskets 510 and 520 may rotate with the switching body 210, and when the switching body 210 rotates to the first position, the clean water inlet passage 110 is communicated with the clean water intermediate passage 211, and the first gasket 510 is clamped therein to perform a sealing function, thereby preventing water from entering a gap between the switching body 210 and the installation cavity 130. Similarly, when the switching body 210 rotates to the second position, the raw water inlet passage 120 communicates with the raw water intermediate passage 212, and the second gasket 520 is interposed therebetween to perform a sealing function.
It is understood that the first gasket 510 and the second gasket 520 may be disposed around the purified water inlet passage 110 and around the outlet of the raw water inlet passage 120. Thus, when the switching body 210 is rotated, the first packing 510 and the second packing 520 may both function as a seal to prevent water from entering a gap between the switching body 210 and the installation cavity 130.
