Detailed Description

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 embodiment of the utility model provides a faucet water purifier. As shown in fig. 1, the faucet water purifier may include a housing 100, a filter assembly 200, and a waterway switching assembly 300.

Housing 100 may be used to house filter assembly 200 and waterway switch assembly 300. The housing 100 may comprise any suitable structure, such as a cylindrical shape or a drop shape, etc. The faucet water purifier may be connected to a faucet through the housing 100. The universal head 150 can be further arranged on the shell 100, so that after the faucet water purifier is connected with a faucet, a user can adjust the water outlet direction of the faucet water purifier through the universal head 150, and the use experience is improved. As shown in fig. 2, the housing 100 may have a raw water inlet 101, a raw water outlet 102, and a purified water outlet 103. The raw water inlet 101 may be connected to a faucet. Raw water may enter the faucet purifier through the raw water inlet 101. If the raw water is not filtered, it can be discharged from the raw water outlet 102. The raw water is filtered and then can be discharged from the purified water outlet 103.

The filter assembly 200 may include any filter cartridge, whether present or as may come into existence in the future. The filter element can comprise one or more of a PP cotton filter element, an activated carbon filter element or a ceramic filter element. As shown in fig. 3-4, the filter assembly 200 may have a clear water passage 210. The purified water passage 210 may communicate between the raw water inlet 101 and the purified water outlet 103. The clear water passage 210 may pass through the filter cartridge. After passing through the water purification passage 210, the raw water is filtered by the filter element to generate purified water. A gap between the filter assembly 200 and the case 100 may form a raw water passage 220. The raw water passage 220 may communicate between the raw water inlet 101 and the raw water outlet 102. Thus, the raw water passing through the raw water passage 220 may not be filtered by the filter assembly 200.

As shown in fig. 1, waterway switching assembly 300 may include a closure 310 and an operating member 320. Wherein the block piece 310 can be moved between the first station and the second station by the operation member 320. The block piece 310 may comprise any type of member having a blocking function, such as a valve in a gate valve, a spool in a slide valve, or a ball shaft in a ball valve. The movement of the closure 310 may include translation, rotation, or other movement. The operating member 320 may be directly connected to the block piece 310 or indirectly connected to the block piece 310. In one embodiment, the blocking member 310 may be a ball shaft, and the operating member 320 may be an operating handle connected to the ball shaft, and a user may rotate the handle to rotate the ball shaft, so that the ball shaft moves between the first station and the second station. In another embodiment, the blocking member 310 may be a spool in a spool valve, and the operating member 320 may be an electromagnet that translates the spool. The magnetic force generated by the electromagnet drives the valve core to move between the first station and the second station. The block piece 310 and the operation member 320 may be formed in various combinations, and in particular, those skilled in the art may reasonably select them according to actual use requirements.

When the blocking member 310 is located at the first station, the blocking member 310 may block the raw water passage 220. When the block piece 310 is located at the second station, the block piece 310 may conduct the raw water passage 220. When the blocking member 310 is located at the first station, since the raw water passage 220 is blocked, raw water may enter the water purification passage 210. The raw water passing through the purified water passage 210 may be filtered by the filter assembly 200 to generate purified water, and discharged through the purified water outlet 103. When the block piece 310 is located at the second station, the raw water passage 220 is conducted. Since the filter assembly 200 generates a certain back pressure to the water flowing therethrough, and the raw water passage 220 has a smaller back pressure than the purified water passage 210 because the filter assembly 200 is not disposed in the raw water passage 220. When both the water purification passage 210 and the raw water passage 220 are in a conductive state, the raw water may be discharged through the raw water passage 220 since the water flow may flow along the passage having the smallest pressure. In some cases, a certain back pressure may be formed due to an excessive water flow in the raw water passage 220, and a part of the raw water may be pressed into the purified water passage 210, and finally, purified water is discharged from the purified water outlet 103. However, in this case, the yield of purified water may be low and may not be considered, so that it will not be described in detail hereinafter.

Accordingly, in the faucet water purifier having the above arrangement, a user can switch raw water between the water purification passage 210 and the raw water passage 220 by the waterway switching unit 300. When the water required by the user is raw water, the plugging member 310 may conduct the raw water channel 220, and the raw water may directly flow out from the raw water channel 220 without being filtered. When the water required by the user is purified water, the plugging member 310 may plug the raw water channel 220, and the raw water may flow out after being filtered by the purified water channel 210. The faucet water purifier can meet different water requirements of users.

Illustratively, the faucet water purifier may further include a partition 400 disposed within the housing 100. The partition 400 and the housing 100 may surround to form the raw water chamber 120. After entering the faucet water purifier, the raw water may first enter the raw water chamber 120. The partition 400 may be provided thereon with a partition through-hole 410. The partition through-hole 410 may form a part of the raw water passage 220. When the block piece 310 is at the first station, the block piece 310 may block the partitioning member through-hole 410. In the embodiment shown in fig. 3-4, the partition 400 may partition the housing into an upper portion and a lower portion, wherein the upper portion of the partition 400 and the housing 100 may form the raw water chamber 120. In other embodiments, the partition 400 may also separate the housing 100 into left and right portions or other configurations. The spacer through-hole 410 may penetrate the spacer 400. As shown in fig. 5, when the blocking member 310 is at the first station, the blocking member 310 may block the partition member through hole 410, and the raw water may sequentially pass through the raw water chamber 120 and the purified water passage 210 in the direction of the arrow shown in fig. 3 to be discharged from the purified water outlet 103. As shown in fig. 6, when the blocking member 310 is at the second station, the blocking member 310 may open the partition through-hole 410, and the raw water may sequentially pass through the raw water passage 220 formed by the raw water chamber 120 and the partition through-hole 410 in the direction of the arrow in fig. 4 to be discharged from the raw water outlet 102. It should be noted that, since the filter assembly 200 is not hermetically connected to the partition 400, the raw water may be discharged through a gap between the filter assembly 200 and the partition 400.

It should be noted that, when the blocking member 310 is at the first station and the blocking member 310 blocks the partition member through hole 410, the partition member 400 may be connected to the casing 100 in a sealing manner in order to prevent raw water from being discharged through a gap between the partition member 400 and the casing 100. Preferably, as shown in fig. 3, the partition 400 and the bottom of the case 100 may be connected by ultrasonic welding to form a sealed connection. Of course, in other embodiments, this may also be achieved by providing a seal between the partition 400 and the housing.

Therefore, the faucet water purifier with the arrangement can divide the shell 100 into the raw water cavities through the partition 400, raw water entering the faucet water purifier can firstly enter the raw water cavities, and then the purpose of water path switching is achieved according to the station where the blocking piece 310 is located.

Illustratively, as shown in fig. 1, the faucet water purifier may further include a first sealing member 500. The first seal 500 may be located between the block piece 310 and the partition 400. The first seal 500 may be provided with a first seal through hole 501 and a second seal through hole 502. The first seal through hole 501 may be aligned with the spacer through hole 410. Wherein the block piece 310 may snap into the first seal member through hole 501 when the block piece 310 is in the first station. The first sealing member 500 may seal between the blocking member 310 and the separator through-hole 410, thereby blocking the separator through-hole 410. When the block piece 310 is in the second station, the block piece 310 may be snapped into the second sealing member through hole 502, rendering the partition member through hole 410 conductive. The shape of the first seal 500 may be adapted to the closure 310. In embodiments where the blocking member 310 is a ball, the first sealing member 500 may be a ring-shaped sealing ring. A sealing ring in a ring shape may be embedded in the partition member through hole 410, and when the blocking member 310 is located at the first station, the sealing ring may be interposed between the blocking member 310 and the partition member 400 to achieve a sealing effect. In the embodiment shown in fig. 1, the first sealing member 500 may be an 8-shaped gasket. The first seal 500 may be composed of two separate annular gaskets, or may be a single piece. Preferably, the first seal 500 is a unitary piece. Two through holes, which are a first seal through hole 501 and a second seal through hole 502, respectively, may be provided on the first seal 500 in one piece, and the first seal through hole 501 may be aligned with the partition through hole 404 when the first seal 500 is attached to the partition 400.

It should be noted that, in the embodiment shown in fig. 1, the first sealing member 500 may be provided with a positioning protrusion (not shown in the figure due to the angle of view) on the end surface facing the partition 400. The positioning projection may be annularly provided around the first seal through hole 501. Wherein, the positioning protrusion provided around the first sealing member through hole 501 may be inserted into the partition member through hole 410 so that the partition member through hole 410 fixes the first sealing member 500.

For the partition through hole 410, the first sealing element 500 having the first sealing element through hole 501 may form a sealing effect, but after the first sealing element 500 is respectively provided with the first sealing element through hole 501 and the second sealing element through hole 502, when the blocking piece 310 is at the first station, the blocking piece 310 may be clamped into the first sealing element through hole 501, and when the blocking piece 310 is at the second station, the blocking piece 310 may be clamped into the second sealing element through hole 502, so that the positioning may be realized when the blocking piece 310 is at the first station and the second station, so that the blocking piece 310 may be stopped at the first station or the second station, and the phenomenon that the blocking piece 310 moves when the user does not operate the operating member 320 is prevented. In addition, with the arrangement, in the moving process of the plugging piece 310 in the first station and the second station, the blocking situation when the plugging piece 310 is blocked into the first sealing element through hole 501 or the second sealing element through hole 502 can be fed back to the user through the operation member 320, so that the user can sense the position of the plugging piece 310 when operating the operation member 320, and the user can move the plugging piece 310 more accurately.

Further, the spacer 400 may be further provided with a spacer blind hole 420. The spacer blind hole 420 may be aligned with the second seal through hole 502. Similar to the above positioning projection around the first seal through hole 501, a similar positioning projection may be provided around the second seal through hole 502, and the first seal 500 may be more firmly fixed to the partitioning member 400 by being fitted into the partitioning member blind hole 420.

Illustratively, the faucet water purifier may further include a holder 600. The holder 600 may be disposed within the housing 100. The partition 400 may be fixed to the case 100. The fixing base 600 may be fixed to the partition 400. The filter assembly 200 may be fixed to the holder 600. The spacer 400 may be fixed to the case 100 by a snap connection, a threaded fastener connection, or welding, etc. Preferably, the partition 400 may be connected to the bottom surface of the case 100 by ultrasonic welding, thereby integrating the partition 400 with the case. In the embodiment shown in fig. 1, the fixing base 600 may be detachably connected to the partition 400, and the connection manner may include a snap connection or a screw connection. The filter assembly 200 can be connected with the fixing base 600 by plugging. Of course, in the embodiment not shown, any other suitable connection means may be used to connect the fixing seat 600 and the partition 400 and the fixing seat 600 and the filter assembly 200. Therefore, through the arrangement, the filter assembly can be fixed in the shell 100 through the fixing seat 600, and if the fixing seat 600 and the filter assembly 200 form a detachable connection, the filter assembly 200 can be conveniently replaced.

For example, the spacer 400 may be provided with a lug 430 extending toward the fixing base 600. The holder 600 may be rotatably engaged to the lug 430. In the embodiment as shown in fig. 1, the partition 400 may be provided with a plurality of arc-shaped lugs 430 at intervals in a circumferential direction thereof. The plurality of lugs 430 may extend in a direction toward the holder 600. Correspondingly, the fixing base 600 may be provided with a plurality of arc-shaped slots 630 which can be matched with the lugs 430. The lugs 430 may be inserted into the slots 630 to connect the partition 400 with the fixing base 600. Further, in order to improve the connection stability of the partition 400 and the fixing base 600, a sliding groove 431 may be further provided on the lug 430, as shown in fig. 7. The slide groove 431 may extend in the axial direction of the partition 400. Accordingly, in the groove hole 630, a slider (not shown in the drawings) corresponding to the slide groove 431 may be provided. When the user connects the partition 400 to the fixing base 600, the user can insert the lug 430 into the slot 630, align the sliding groove 431 with the slider, and rotate the partition 400 and the fixing base 600 relatively, so that the slider can slide into the sliding groove 431 to limit the axial direction of the partition 400 and the fixing base 600. Further, in order to be able to restrict the position of the partitioning member 400 and the fixing base 600 in the circumferential direction, a positioning groove 432 extending in the axial direction of the partitioning member 400 may be further provided on the boss 430, and a positioning protrusion 631 extending in the axial direction of the fixing base 600 may be provided in the groove hole 630. When the partition 400 and the fixing base 600 rotate to a certain angle, the positioning protrusion 631 may be engaged with the positioning groove 432, thereby restricting the rotation between the partition 400 and the fixing base 600. It is understood that in other embodiments, a sliding block may be disposed on the lug 430, a sliding slot may be disposed in the slot 630, a positioning slot may be disposed on the lug 430, and a positioning protruding strip may be disposed in the slot 630. The connection and matching modes can be various, and those skilled in the art can make appropriate selections according to actual use conditions, which is not described in detail.

Thus, with this arrangement, the block piece 310 and the operation member 320 can be sandwiched between the partitioning member 400 and the fixing base 600 by the fixing base 600 to limit the movable range of the block piece 310 and the operation member 320. Moreover, the partition 400 and the fixing base 600 may be detachably connected, and the installation and maintenance of the blocking member 310 and the operation member 320 may be facilitated.

For example, the fixing base 600 may be provided with a plurality of mounting holes 610. A plurality of mounting holes 610 may be spaced around the center of the fixing base 600. In the embodiment that the fixing base 600 is connected to the partition 400 by screwing, since the gap between the fixing base 600 and the casing 100 is small, it is difficult for a user to find a point of effort on the fixing base 600 to perform an operation of rotating the fixing base 600 during installation. In order to solve the above problem, as shown in fig. 1, a plurality of mounting holes 610 are provided on the fixing base 600, and the plurality of mounting holes 610 may be uniformly distributed in the circumferential direction of the fixing base 600, and the distances from the center of the fixing base 600 are equal. Of course, it is understood that the plurality of mounting holes may be distributed on the fixing base 600 at will. After the user inserts the lug 430 of the partition 400 into the slot 630 of the fixing seat 600, the lug can be inserted into the plurality of mounting holes 610 by means of a tool, and the tool is rotated to drive the fixing seat 600 to rotate, so as to realize the rotation-locking connection with the partition 400. It can be seen that, by this arrangement, the user can conveniently attach the fixing base 600 to the partition 400. Of course, in the embodiment where the mounting hole 610 is a through hole, it may also have a function of conducting raw water, becoming a part of the raw water passage 220.

Illustratively, as shown in fig. 9, the bottom surface of the case 100 may be provided with an annular boss 130 facing the partition 400. The annular boss 130 may be disposed around the purified water outlet 103. The partition 400 may be annularly fitted over the annular boss 130. The holder 600 may be provided with a holder center pipe 620 extending toward the partitioning member 400. The mount center tube 620 may be sealingly connected to the annular boss 130. The clean water passage 210 may be connected to the clean water outlet 103 through the holder center tube 620. In the embodiment as shown in fig. 9, the pure water outlet 103 may be disposed at the center of the bottom surface of the housing 100, and the raw water outlet 102 may be disposed on the bottom surface of the housing 100 in a ring shape around the pure water outlet 103. The annular boss 130 is disposed between the purified water outlet 103 and the raw water outlet 102. The annular boss 130 may be formed to extend in a cylindrical shape in a direction toward the partition 400. The partition 400 is fitted over the annular boss 130 and is sealingly coupled to the bottom surface of the housing 100. Wherein, an end surface of the partition 400 facing the bottom surface of the case 100 may be provided with an annular groove 440. The annular groove 440 communicates with the partition through-hole 410. The sidewall of the annular groove 440 may be joined to the bottom surface of the case 100 by ultrasonic welding. A space formed between the annular groove 440 and the bottom surface of the housing 100 may be a part of the raw water passage 220. The outer circumferential wall of the fixing base center pipe 620 may be sleeved with a sealing ring, and when the fixing base center pipe 620 is inserted into the annular boss 130, the sealing ring forms a seal between the fixing base center pipe 620 and the annular boss 130. Wherein, a space formed between the holder central tube 620, the annular boss 130, and the bottom surface of the housing 100 may be a part of the clean water passage 210.

Therefore, the fixing seat 600 and the housing 100 can be hermetically connected through the arrangement, the water purifying channel 210 and the raw water channel 220 are separated, and the structure is simple and easy to realize.

For example, the end surface of the filter assembly 200 facing the fixing base 600 may be provided with a filter assembly center tube 230. The filter assembly center tube 230 may form a portion of the clean water channel 210. The filter assembly center tube 230 may be sealingly inserted into the holder center tube 620. As shown in fig. 9, a sealing ring may be disposed around the outer circumferential wall of the central tube 230 of the filter assembly, and when the central tube 230 of the filter assembly is inserted into the central tube 620 of the holder, the sealing ring may form a seal between the central tube 230 of the filter assembly and the central tube 620 of the holder. Through this setting, filtering component 200 can with fixing base 600 sealing connection, simple structure easily realizes.

Exemplarily, the operating member 320 may include a holding part 321, an operating part 322, and a second sealing part 323. The holding member 321 is rotatably disposed in the housing 100 and fixed relative to the block piece 310. One end of the operating member 322 may be connected to the holding member 321 and the other end protrudes out of the housing 100. The second sealing member 323 may seal between the holding member 321 and the case 100. The holding member 321 can move the plugging member 310 between the first station and the second station by the operation member 322.

In the embodiment shown in fig. 10, the holding member 321 may include a "bowl" structure, and the "bowl" structure may catch the block piece 310 therein, and as the holding member 321 moves, the holding member 321 may move the block piece 310. For example, in order to enable the stopper 310 to better block the partition through-hole 410, an elastic member may be provided between the stopper 310 and the holding portion 321 to generate a force toward the stopper 400 with respect to the stopper 310. The elastic member may be a spring. The operation member 322 extending out of the housing 100 may have a handle for facilitating the user to operate the operation member 322. The second sealing element 323 can make the holding member 321 still form a sealing effect with the casing 100 during the moving process, and prevent the water flow in the casing 100 from flowing out through the gap between the holding member 321 and the casing 100. It will thus be appreciated that this arrangement allows a user to conveniently control the movement of the closure 310 between the first and second stations.

Illustratively, as shown in fig. 1, the housing 100 is provided with a mounting through-hole 140. The mounting through-hole 140 may be provided on a sidewall of the case 100. Of course, in other embodiments, the mounting through hole 140 may be disposed at the top of the housing 100 or at any other position. The holding member 321 may include a shaft portion 321a and a cantilever portion 321 b. The shaft portion 321a is rotatably disposed in the mounting through-hole 140. The second seal 323 may be interposed between the shaft portion 321a and the sidewall of the mounting through-hole 140. By arranging the shaft portion 321a, the user can rotate the holding member 321 by pulling the operating member 322. In this embodiment, the first and second stations may be disposed on an arc centered on the shaft portion 321 a. This arrangement can reduce the moving range of the holding member 321 and the operating member 322, thereby reducing the size of the waterway switching assembly 300.

Preferably, the block piece 310 may be in the form of a sphere. The ball may have a good blocking effect on the partition through-hole 410, and when installed, the installation direction of the blocking member 310 may not be considered, reducing the probability of erroneous installation. It will of course be appreciated that the closure member 310 may also comprise any suitable structure, for example, may be in the form of a plate or a cylinder, etc.
