When the handle 600 is controlled to the raw water mode, tap water flows out through the raw water port 700. When the control handle 600 is switched to the water purification mode, tap water flows into the filter element in the housing 100, and purified water treated by the filter element flows out from the water purification port 800. After the filter element is used for a period of time, impurities such as water rust and the like can be attached to the filter element. At this time, the color of the filter element becomes dark and the purification capability becomes weak, and the working state of the filter element in the housing 100 can be observed in real time through the light transmission window 200.

The structure of the faucet water purifier of the present invention will be described in detail with reference to the accompanying drawings. As shown in fig. 2-3, the faucet water purifier may include a housing 100, a light transmissive window 200, and a seal 300. The housing 100 is provided with an opening 110, the transparent window 200 is covered and buckled on the opening 110, and the sealing member 300 forms a seal between the housing 100 and the transparent window 200.

Specifically, in the installation process of the light-transmitting window 200, the light-transmitting window 200 is only required to be aligned with the opening 110 and inserted into the shell 100, the light-transmitting window 200 is rotated, and the rotating clamping part 120 is rotatably clamped in the rotating clamping adapting part 210, so that the connection between the light-transmitting window 200 and the shell 100 can be realized, the installation process is simple and convenient, and the production efficiency of the faucet water purifier is effectively improved. Moreover, compared with the scheme of installing the observation window through a clamping joint on the market, the light-transmitting window 200 is connected with the shell 100 through the rotary clamping joint adapting part 210, and the connection stability is better. The rotary clamping adapting part 210 and the rotary clamping part 120 have simple structures and lower cost, and further reduce the production cost of the faucet water purifier. Specifically, in order to ensure that the light-transmitting window 200 can smoothly perform the rotation of the card, the light-transmitting window 200 may have a circular structure. Illustratively, the transparent window 200 may be made of a transparent material as a whole. Alternatively, the transparent window 200 may be partially made of a transparent material. For example, the radial center of the transparent window 200 is made of a transparent material, so that the filter element and other structures inside the housing 100 can be clearly observed through the transparent window 200.

The sealing member 300 and the light-transmissive window 200 may be provided independently of each other. Illustratively, the sealing member 300 may include a sealing ring sandwiched between the light transmissive window 200 and the housing 100. Alternatively, in other embodiments not shown, the seal may be part of the light transmissive window. For example, the sealing member may be an elastic material disposed at an outer peripheral edge of the light-transmitting window, and the elastic material is fixedly connected to the light-transmitting window in a sealing manner, abuts against the housing, and is squeezed to fill a gap between the light-transmitting window and the housing, so as to seal the housing and the light-transmitting window. In another embodiment, the sealing member may be an elastic film covering the light-transmissive window, and even the sealing member may be an elastic film covering the housing to ensure sealing of the housing and the light-transmissive window. It is understood that the above description is only exemplary and not restrictive of the relationship between the sealing member and the transparent window, and any other sealing method may be adopted herein to ensure the sealing between the casing and the transparent window.

Above-mentioned scheme is through setting up printing opacity window 200, guarantees to observe the in service behavior of parts such as the filter core in the casing 100 in real time through printing opacity window 200, can in time discover when the filter core discolours or damages to operation such as maintenance or change has improved leading water purifier's practicality. The light-transmitting window 200 is installed through the rotary clamping part 120 and the rotary clamping adaptive part 210, the accessory structure is simple, the production cost is lower, the installation process is convenient and fast, and the production efficiency of the faucet water purifier is effectively improved. The light-transmitting window 200 has better stability after being installed, and the durability of the faucet water purifier is ensured.

In an embodiment not shown, the rotation-locking part can be installed at the edge of the transparent window, the rotation-locking adapter part can be arranged on the surface of the shell, and the outer edge of the transparent window is connected with the shell in a rotation-locking mode. Alternatively, as shown in fig. 3 to 5, the housing 100 may be provided with an inwardly recessed recess 130, the opening 110 is disposed on the bottom wall 131 of the recess 130, the rotation-locking fitting portion 210 is disposed on the outer circumferential surface of the light-transmitting window 200, and the rotation-locking portion 120 is disposed in the recess 130. Thus, the transparent window 200 and the housing 100 are rotatably clamped in the recess 130, and the transparent window 200 is fixedly mounted on the outer peripheral surface thereof, so that water in the housing 100 can be better resisted from generating upward pressure on the transparent window 200 in the axial direction, and the stability of connection between the transparent window 200 and the housing 100 is ensured. In addition, the installed light-transmitting window 200 does not occupy the space outside the housing 100, so that the faucet water purifier has a more beautiful appearance.

Illustratively, the sealing member 300 is interposed between the sidewall 132 of the recess 130 and the outer circumferential surface of the light-transmitting window 200 along the radial direction of the light-transmitting window 200. Thus, the sealing member 300 is deformed by compression to fill the gap between the sidewall 132 of the recess 130 and the outer wall of the transparent window 200, so that the sealing effect can be better ensured. Moreover, the sealing member 300 is hidden in the gap between the side wall 132 of the recess 130 and the outer wall of the light-transmitting window 200, so that on one hand, the space of the faucet water purifier is not occupied in the axial direction, and then a larger filter element can be selected, and the water purifying efficiency is improved; on the other hand, the sealing element 300 can be prevented from being exposed, so that the outer surface of the faucet water purifier is smoother.

Illustratively, as shown in fig. 5, the sealing member 300 may be closer to the outside of the housing 100 than the screw chucking portion 120 and the screw chucking fitting portion 210. Thus, the arrangement of the rotation locking part 120 and the rotation locking adapting part 210 can block part of water, reduce the amount of water flowing into the sealing member 300, relieve the pressure of the sealing member 300 and ensure the sealing effect of the sealing member 300. Moreover, the sealing member 300 can prevent external foreign matters from entering the rotary card connecting structure, so as to avoid the failure of the rotary card connecting structure.

Further, the outer circumferential surface of the light transmission window 200 may be provided with an annular groove 220, and the sealing member 300 is fixed in the annular groove 220. Specifically, the annular groove 220 may extend along a circumferential direction of the light transmissive window 200. The seal 300 may accordingly be provided as an annular sealing ring. After the ring-shaped sealing ring is placed in the annular groove 220, the light-transmitting window 200 and the housing 100 are installed. The position of sealing member 300 can be better fixed in the setting of annular groove 220, and sealing member 300 can fill the space of annular groove 220 better after being extruded deformation, promotes sealed effect.

Illustratively, the light transmissive window 200 may be embedded within the recess 130, with an outer surface of the light transmissive window 200 flush with an outer surface of the housing 100. Therefore, the outer surface of the faucet water purifier can be smoother. The light transmissive window 200 may be completely embedded in the recess 130 or partially embedded in the recess 130. Fig. 5 shows a case where the light transmission window 200 is partially embedded in the recess 130, in which case the light transmission window 200 may protrude into the housing 100 through the recess 130. Further, as shown in fig. 5, the outer surface of the casing 100 may have a certain curvature, and the outer surface of the light-transmitting window 200 has a curvature adapted thereto. Thus, the gap between the light-transmitting window 200 and the casing 100 is small, dust is not easy to accumulate in the gap, and the appearance of the faucet water purifier is better ensured to be neat. In addition, the faucet water purifier is higher in appearance integration degree and more attractive in appearance.

For example, the rotation-locking portion 120 may include a locking rib 121 (shown in fig. 4) protruding radially inward, and the rotation-locking fitting portion 210 may include a locking groove formed on an outer circumferential surface of the light-transmissive window 200. As shown in fig. 6-7, the snap groove may include a longitudinal groove 211 and a transverse groove 212. The longitudinal groove 211 extends in the axial direction of the light transmission window 200, and the lateral groove 212 extends in the circumferential direction of the light transmission window 200. The transverse grooves 212 and the longitudinal grooves 211 may communicate with each other. The longitudinal grooves 211 and the transverse grooves 212 may be connected as inverted L-shaped grooves. The longitudinal groove 211 extends toward the inside of the housing 100 to the edge of the transparent window 200, and the width of the longitudinal groove 211 is greater than or equal to the width of the engaging rib 121, so that the engaging rib 121 is engaged in the transverse groove 212 via the longitudinal groove 211. It can be understood that, when the window is installed, the engaging rib 121 is inserted into the recess 130 along the longitudinal groove 211 until the engaging rib 121 can abut against the top wall of the transverse groove 212, and the engaging rib 121 can be engaged in the transverse groove 212 by rotating the transparent window 200. After the snap connection, the transverse groove 212 limits the position of the snap rib 121 in both the axial direction and the radial direction, thereby ensuring a stable connection between the transparent window 200 and the housing 100. Therefore, the installation of the light-transmitting window 200 and the shell 100 can be realized by screwing the card, the installation process is simple, and the connection between the shell 100 and the light-transmitting window 200 is more stable after the installation.

For example, in conjunction with fig. 6-9, the light transmission window 200 may be provided with an annular projection 230 and a plurality of projections 240 on an outer circumferential surface thereof. The seal 300 may be secured to the annular boss 230. The plurality of tabs 240 are closer to the interior of the casing 100 relative to the annular boss 230 and spaced from the annular boss 230. The plurality of protrusions 240 are spaced apart along the circumferential direction of the transparent window 200, a longitudinal groove 211 is formed between every two adjacent protrusions 240, a transverse groove 212 is formed between each of the plurality of protrusions 240 and the annular boss 230, and the snap ribs 121 correspond to the transverse grooves 212 one to one. Specifically, taking the embodiment in fig. 8 as an example, a plurality of protrusions are disposed on the outer peripheral surface of the light-transmitting window 200, and for the sake of clarity, the protrusions are respectively labeled as protrusions 240a, 240b, 240c and 240 d. A longitudinal slot 211a is formed between the tabs 240a and 240b, a longitudinal slot 211b is formed between the tabs 240b and 240c, and a longitudinal slot 211c is formed between the tabs 240c and 240 d. Transverse slots 212a, 212b and 212c are formed between the lugs 240a, 240b and 240c and the annular boss 230, respectively. It is understood that the lateral groove 212a and the longitudinal groove 211a constitute an engagement groove, the lateral groove 212b and the longitudinal groove 211b constitute an engagement groove, and the lateral groove 212c and the longitudinal groove 211b constitute an engagement groove. The plurality of engaging grooves may constitute the screw-fit engaging portion 210. By providing a plurality of protrusions 240, the snap rib 121 can slide into the recess 130 through the longitudinal slot 211 formed between two protrusions 240. Furthermore, the engaging ribs 121 can be engaged into the plurality of transverse grooves 212 formed between the annular bosses 230 and the protrusions 240 one by one, so that the stress of the transparent window 200 in the circumferential direction is more balanced, and the connection stability between the transparent window 200 and the housing 100 is ensured.

For example, as shown in fig. 4, the snap rib 121 may protrude radially inward from the edge of the opening 110. The engaging ribs 121 may be plural, and the plural engaging ribs 121 are spaced apart from each other by a predetermined distance. For example, the plurality of engaging ribs 121 may be uniformly disposed on the bottom wall 131 of the recess 130. The plurality of engaging ribs 121 can make the connection between the transparent window 200 and the housing 100 more secure. In other embodiments not shown, the number of the snap ribs 121 may be one. The radially inward protruding clamping rib 121 is arranged at the opening 110 of the shell 100 with relatively high structural strength, so that the clamping rib 121 is still ensured not to be bent or damaged easily, and the durability of the faucet water purifier is ensured. Also, it is easier to process the engaging rib 121 at this position. Furthermore, the engaging rib 121 may be integrally formed with the bottom wall 131, so that the engaging rib 121 and the housing 100 are more firmly connected. Alternatively, the engaging rib 121 may be disposed on the sidewall 132 of the recess 130, for example, in the middle or the top of the sidewall 132.

As shown in fig. 6-8, a stop rib 250 is disposed between at least one of the plurality of protrusions 240 and the annular boss 230. The stop rib 250 may be located at an end of the transverse slot 212 distal from the longitudinal slot 211. When the transparent window 200 is mounted, the engaging rib 121 abuts against the stopping rib 250. Illustratively, referring to the embodiment of fig. 8, a stop rib 250 may be provided between the protrusion 240a and the annular boss 230. In other embodiments not shown, stop ribs may be provided between more lugs and the annular boss 230. The stop rib 250 may be located at an end of the transverse slot 212a distal from the longitudinal slot 211 a. In the illustrated embodiment, the stop rib 250 is located at the left end of the transverse slot 212 a. After passing through the longitudinal groove 211a, the light transmission window 200 is rotated, and the engagement rib is inserted into the lateral groove 212 a. During insertion, one end of the engaging rib slides in the transverse groove 212a and gradually moves away from the longitudinal groove 211a until it abuts against the stopper rib 250, and rotation stops. The stop rib 250 prevents the light-transmitting window 200 from being excessively rotated when being installed, thereby improving the installation efficiency. Illustratively, the stop rib 250 may be connected to the annular boss 230 at one end and extend toward the projection 240 at the other end. For example, as shown in fig. 7, an end of the stopping rib 250 extending toward the protrusion 240 may extend to the protrusion 240 and directly connect with the protrusion 240, and a transverse groove 212 with one end closed is formed between the protrusion 241 and the annular boss 230 to achieve a better stopping effect.

Illustratively, at least one of the plurality of protrusions 240 may be provided with a setback prevention rib 260 extending toward the annular boss 230. The anti-retreat rib 260 is located at the end of the transverse groove 212 connected to the longitudinal groove 211, and the engaging rib 121 abuts against the anti-retreat rib 260. In the illustrated embodiment, the stop rib 250 is located at the right end of the transverse slot 212. The anti-receding rib 260 is provided at the entrance of the transverse groove 212 with a certain gap from the annular boss 230, and the engaging rib can be inserted into the transverse groove 212 through the gap. Like this, the one end that inserts in the transverse groove 212 in being close to the entrance offsets with preventing moving back protruding muscle 260, can prevent effectively that the block muscle from roll-off in the transverse groove 212, and then the printing opacity window 200 after the restriction installation is at ascending removal in week, guarantees the firm degree of being connected between printing opacity window 200 and the casing 100. Preferably, as shown in fig. 7, the anti-retreat rib 260 and the stopper rib 250 may be provided on the same projection 240. Thus, after the clamping rib is clamped into the transverse groove 212 corresponding to the lug 240, the positioning can be realized more efficiently, and the assembly efficiency is higher. Further, a withdrawal prevention rib 260 and a stopper rib 250 may be provided on each of the protrusions 240 to ensure high assembling efficiency. Alternatively, in an embodiment not shown, the anti-retreat rib and the stopper rib may be provided on different projections, respectively.

Further, as shown in fig. 7, a side of the retreat preventing rib 260 facing the longitudinal groove 211 may be provided with a chamfer 261. The chamfer 261 may be a slope that is disposed obliquely upward to a side away from the longitudinal groove 211. Further, the gap between the anti-receding rib 260 and the annular boss 230 may be slightly smaller than the thickness of the engaging rib. During the rotation of the transparent window 200, the engaging rib is pushed into the transverse groove 212 by the chamfer 261, and the stop rib 250 limits the engaging rib to slide out of the transverse groove, so as to control the reverse rotation of the transparent window 200. Thus, in the installation process of the light-transmitting window 200, the clamping ribs can smoothly slide through the chamfer 261 and enter the transverse groove 212, and the installation efficiency is improved.

Illustratively, as shown in fig. 8-9, two corners of the plurality of bumps 240 away from the transverse groove 212 are provided with chamfers 241 such that the opening of the longitudinal groove 211 is flared. Specifically, referring to the embodiment in fig. 8, taking one of the longitudinal grooves 211b as an example, the corner of the slider 240b near one side of the longitudinal groove 211b is provided with a chamfer 241a, and the corner of the slider 240c near one side of the longitudinal groove 211b is provided with a chamfer 241 b. The chamfer 241a may be an inclined surface that is disposed downward along the middle of the sidewall of the slider 240b near the longitudinal groove 211b and inclined toward the sliding groove 211 a. Accordingly, the chamfer 241b is a slope that is disposed downward along the middle portion of the sidewall of the slider 240c near the longitudinal groove 211b and is inclined toward the sliding groove 211 c. Thus, the opening of the longitudinal groove 211b is gradually increased from top to bottom. The clamping ribs enter the longitudinal groove 211 from a larger opening, can be positioned and slide into the longitudinal groove 211 more quickly, and further improves the installation efficiency of the light-transmitting window 200.

As shown in fig. 8-9, along the axis of the light transmissive window 200, the plurality of protrusions 240 have ends near the interior of the housing 100, which may be provided with chamfers 242. Specifically, the chamfer 242 is a slope provided obliquely downward and toward the central axis of the housing along the peripheral wall of the boss 240. Thus, after the end portion contacts with the edge of the bottom wall 131 of the recess 130, the chamfer 242 can ensure that the transparent window 200 can slide along the axial direction of the transparent window 200 more smoothly, so as to complete the subsequent installation process and improve the installation efficiency of the transparent window 200.

For example, as shown in fig. 1-2, the light transmissive window 200 may be disposed at the top of the housing 100. In general, the faucet water purifier is installed on a faucet in a kitchen, and the light-transmitting window 200 is disposed at the top of the housing 100, so that a user can observe the inside of the housing 100 through the light-transmitting window 200 more conveniently. Or, according to different use scenes and requirements, the light-transmitting window can be arranged at any position of the side surface of the shell, so that the interior of the shell can be observed through the light-transmitting window, and the limitation is not needed.
