Abstract
Description
Technical Field
[0001] This utility model relates to the field of bathroom fixtures technology, specifically to faucets and taps. Background Technology
[0002] Water taps are commonly used tools in kitchens and bathrooms. To improve their filtration performance, some manufacturers have built-in filter mechanisms into the water taps. The water entering the tap is filtered by the filter mechanism before being discharged. Common filter mechanisms are fixed by clamping the upper and lower shells of the tap. The lower shell usually also needs to be equipped with a nozzle assembly. The clamping and fixing of the filter mechanism complicates the structure of the lower shell and makes the installation of the nozzle mechanism more troublesome, which needs to be improved. Utility Model Content
[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:
[0004] This application discloses a faucet, including an upper housing, a lower housing, a filter mechanism for filtration, and a nozzle assembly for water dispensing. The filter mechanism is located within a cavity formed by the upper and lower housings, and the nozzle assembly is located at the outlet of the lower housing. The filter mechanism includes a top cover, a bottom cover, and a cylinder for containing filter components. The top cover is provided at the top opening of the cylinder, and the bottom cover is provided at the bottom opening of the cylinder. The bottom cover is connected to the upper housing and fixed as a whole. The water outlet hole provided at the bottom cover faces the nozzle assembly.
[0005] This solution improves the installation structure of the filter mechanism. The bottom cover is connected to the upper housing for fixation, eliminating the need for the lower housing to be clamped to the upper housing. This simplifies the structure of the lower housing and facilitates the installation of functional mechanisms (such as nozzle assemblies) inside the lower housing.
[0006] For filter components, such as the common top-cover water inlet type or the water inlet type from the peripheral wall of the cylinder, the choice depends on the requirements.
[0007] Furthermore, the bottom cover abuts against the top of the nozzle assembly, and the bottom of the nozzle assembly is fixed to the lower housing. The lower housing is pivotally connected to the upper housing. The relative rotation of the upper and lower housings adjusts the degree of misalignment between the water outlet hole one at the bottom cover and the water inlet hole two at the nozzle assembly. In use, if the upper and lower housings are rotated so that the water inlet hole two and the water outlet hole one at the nozzle assembly are completely misaligned, water cannot flow out. When the water inlet hole two and the water outlet hole one are at least partially aligned, the water filtered by the filtration mechanism flows into the nozzle assembly through the water outlet hole one and the water inlet hole two, and then flows out, which is convenient for use.
[0008] For nozzle assemblies, the required structure or model can be selected from the market according to needs, with the following structure being preferred:
[0009] Furthermore, the nozzle assembly includes a cover plate and a panel for discharging water. The panel is located below the cover plate and the two are fixed together. The panel is fixed to the lower housing cavity wall and the upper part of the panel abuts against the cover plate. The cover plate abuts against the bottom cover located above.
[0010] The bottom surface of the bottom cover is connected to a positioning post with longitudinal elastic telescopic connection. The cover plate is provided with positioning grooves at intervals along the circumference. When the upper and lower shells rotate relative to each other, the positioning post is inserted into the corresponding positioning groove to lock the upper and lower shells in their positions. For example, there are two positioning grooves. When the positioning post extends into the first positioning groove, the second water inlet and the first water outlet are completely misaligned. When the positioning post extends into the last positioning groove, the second water inlet and the first water outlet correspond. Of course, the positioning grooves can also be three or more as needed.
[0011] Furthermore, the cover plate includes an upper plate and a lower plate. The upper plate and the lower plate are fixed together and form a buffer cavity between them. The upper plate is provided with a second water inlet corresponding to the first water outlet of the bottom cover. The lower plate is provided with a second water outlet facing the panel. The upper plate is provided with positioning grooves at intervals. Increasing the buffer cavity helps to promote the uniformity of water output from the panel.
[0012] Furthermore, a guide protrusion is provided on the top surface of the upper plate. The protrusion extends into a guide groove formed on the bottom surface of the bottom cover. When the upper and lower shells rotate relative to each other, the protrusion moves along the guide groove. The bottom surface of the bottom cover has an outwardly protruding post. The post extends into the corresponding pivot holes formed on the upper and lower plates to form a pivot connection with the bottom cover. The docking of the post and the pivot hole helps to improve the stability of rotation. The cooperation between the protrusion and the guide groove also helps to improve the stability of rotation. At the same time, the length of the guide groove can be limited, thereby limiting the range of rotation of the upper and lower shells. For example, when the protrusion abuts against the first end wall of the guide groove, the second water inlet and the first water outlet are completely misaligned. When the protrusion abuts against the last end wall of the guide groove, the second water inlet and the first water outlet correspond.
[0013] Furthermore, it also includes needle plate one and needle plate two. Needle plate one is set at the three water outlet holes formed in the middle of the panel, and needle plate two is set at the four water outlet holes formed around the three water outlet holes. The split needle plate configuration can be designed with different needle plate configurations according to needs to meet different water outlet requirements, etc.
[0014] Furthermore, a top plate is provided protruding from one of the water inlet holes of the upper housing. The top plate abuts against the top cover of the filter mechanism. The abutment between the top plate and the top cover helps to simplify the structure of the upper housing.
[0015] Furthermore, it also includes a connector assembly, which is connected to the water inlet hole on the upper housing. The connector assembly can be selected from the market according to the needs, such as the common universal joint type.
[0016] Furthermore, the bottom cover is threadedly connected to the cavity wall at the opening of the upper shell, facilitating assembly.
[0017] Furthermore, the cylinder is permeable and there is a gap between the cylinder and the corresponding circumferential cavity wall for water conveyance. The gap is connected to a water inlet hole provided on the upper shell. The cylinder is like a common mesh. The water entering the gap enters the cavity through the circumferential wall of the cylinder and then exits from the bottom cover.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

Detailed Implementation
[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0027] Example 1
[0028] like Figures 1-3As shown, in this example, the faucet includes an upper housing 1, a lower housing 2, a filter mechanism 3, and a nozzle assembly 4. In this example, both the upper housing 1 and the lower housing 2 are cylindrical, but other configurations can be selected according to requirements. The upper housing 1 and the lower housing 2 are connected by means of fitting, threaded connection, snap-fit, etc. The filter mechanism 3 is located in the cavity formed by the upper housing 1 and the lower housing 2, and the nozzle assembly 4 is located at the outlet of the lower housing 1. The filter mechanism 3 is used to filter out impurities in the input water, and the filtered water is discharged from the nozzle assembly. The nozzle assembly with the required function can be selected according to needs.
[0029] In this example, the filter mechanism 3 includes a top cover 31, a bottom cover 32, and a cylindrical body 30 for containing the filter components. The cylindrical body 30 is a common cylindrical shape, and the top cover 31 is installed at the top opening of the cylindrical body 30. The top cover 31 is fixed to the top opening of the cylindrical body 30 by means of fitting, snap-fit, or threaded connection. A top plate 102 is formed protruding around the water inlet hole 101 of the upper housing 1, and the top plate 102 abuts against the top cover 31 of the filter mechanism. The abutment between the top plate and the top cover helps to simplify the structure of the upper housing. If the top plates are arranged circumferentially at intervals, or if the top plates abut against the protrusions on the top surface of the top cover, the water entering from the upper housing flows out through the space between the top plates or the space between the protrusions.
[0030] A bottom cover 32 is installed at the bottom opening of the cylinder 30. Similarly, the bottom cover is fixed to the bottom opening of the cylinder by means of fitting, snap-fit, or threaded connection. In this example, the bottom cover 32 is also connected to the upper shell 1 to be fixed as a whole. The fixing methods can be selected such as fitting, snap-fit, or threaded connection. The preferred fixing method is the threaded connection shown in this example. The peripheral wall of the bottom cover 32 is threaded to the bottom opening wall of the upper shell 1, thereby fixing the filter assembly to the upper shell.
[0031] For the filtration mechanism, for example, the hole formed at the top cover 32 communicates with the cavity of the cylinder 30. Water entering from the water inlet 101 at the top of the upper shell 1 flows into the cylinder 30 from the top cover 32, is filtered by the filter components filled in the cylinder, and then discharged from the water outlet 1 formed at the bottom cover. Alternatively, the cylinder can be permeable in its peripheral wall. In this filtration mechanism, the cylinder adopts a mesh structure, and a gap 103 is reserved between the cylinder and the corresponding circumferential cavity wall of the upper shell. The gap 103 communicates with the water inlet 101 formed at the upper shell. The width of this gap can be selected according to requirements. Water entering from the water inlet 1 of the upper shell enters the gap, then enters the cylinder cavity through the mesh of the peripheral wall of the cylinder, and is discharged from the water outlet 1 formed at the bottom cover after filtration.
[0032] The water outlet 34 formed at the bottom cover faces the nozzle assembly 4. Water discharged from the water outlet 34 flows out through the nozzle assembly 4. The position of the water outlet 34 can be in the middle or on the side, and the number of water outlets can be single or multiple, etc. Figure 3 As shown, in this example, a water outlet 34 is formed on the side of the bottom cover 32.
[0033] In this example, the bottom cover 32 abuts against the top of the nozzle assembly 4, and the nozzle assembly 4 is fixed to the cavity wall of the lower housing 2, such as by fitting, snap-fitting, or screw fastening. The lower housing and the upper housing are pivotally connected, such as the first end of the lower housing being fitted onto the tail end of the upper housing for pivotal engagement. In use, the relative rotation of the upper and lower housings can be used to adjust the degree of misalignment between the water outlet hole 1 (34) at the bottom cover and the water inlet hole 2 at the nozzle assembly, thereby adjusting the water flow rate. If the rotation of the upper and lower housings causes the water inlet hole 2 and the water outlet hole 1 at the nozzle assembly to be completely misaligned, water cannot be discharged. When the water inlet hole 2 and the water outlet hole 1 are at least partially aligned, the water filtered by the filtration mechanism flows into the nozzle assembly through the water outlet hole 1 and the water inlet hole 2, and then flows out.
[0034] For nozzle assemblies, the required structure or model can be selected from the market according to needs, with preference given to the use of... Figure 2 , Figure 3 The structure shown, such as the nozzle assembly 4, includes a cover plate and a panel 43 for water outlet. The panel 43 is located below the cover plate. The upper part of the panel is fixed to the cover plate and the lower part of the panel is fitted and fixed to the cavity wall at the outlet of the lower housing 2. The cover plate abuts against the bottom cover 32 located above.
[0035] For the cover plate, the fixation of the cover plate and the panel can be selected, such as by fitting, snap-fit, threaded connection, etc. In this example, the cover plate includes an upper plate 41 and a lower plate 42. The upper plate 41 and the lower plate 42 are fixed together, and a buffer cavity is formed between them. If the upper plate and the lower plate are fixed by fitting, snap-fit, or threaded connection, the increase in the buffer cavity helps to promote the uniformity of water output from the panel.
[0036] The upper plate 41 is formed with a second water inlet corresponding to the first water outlet 34 of the bottom cover 32. The lower plate 42 is formed with a second water outlet facing the panel. The water flowing into the buffer chamber is discharged through the second water outlet and then discharged through the third water outlet on the panel.
[0037] To improve the stability of the connection between the cover plate and the bottom cover, in this example, a protrusion 46 for fixing is formed on the top surface of the upper plate 41. The protrusion 46 extends into the guide groove formed on the bottom surface of the bottom cover 32. A protruding post 33 is formed on the bottom surface of the bottom cover 32. The protruding post 33 extends into the corresponding pivot hole formed in the middle of the upper plate 41 and the lower plate 42 to form a pivot connection.
[0038] For ease of use, a positioning post 36 can be added in this example. For instance, a mounting groove is formed on the bottom surface of the bottom cover 32, and the positioning post 36 is placed longitudinally within the mounting groove. A spring 35 is placed between the top of the positioning post 36 and the corresponding groove wall. The bottom end of the positioning post 36 extends into a circumferentially spaced positioning groove on the upper plate of the cover. The spring allows the positioning post to be elastically extended and retracted on the bottom cover. When force is applied to rotate the lower shell relative to the upper shell, the bottom end of the positioning post extends into one of its positioning grooves or detaches from one positioning groove and extends into an adjacent positioning groove. When the bottom end of the positioning post extends into the positioning groove, it can lock the upper and lower shells in that position. The upper and lower shells can only continue to rotate when external force is applied by hand. If there are two positioning grooves, when the positioning post extends into the first positioning groove, the second water inlet and the first water outlet are completely misaligned. When the positioning post extends into the last positioning groove, the second water inlet and the first water outlet correspond. Of course, the number of positioning grooves can also be three or more as needed.
[0039] To facilitate cleaning, this faucet is also equipped with a needle plate. In this example, it includes a needle plate 45 and a needle plate 44. The needle plate 45 is installed at the three water outlets formed in the middle of the panel 43, and the needle plate 44 is installed at the four water outlets formed around the three water outlets. The configuration of the needle plate 1 and the needle plate 2 can be selected according to the needs to meet different water outlet requirements. The needle plate 45 can be fixed to the three water outlets from the bottom of the panel by a threaded connection. Of course, other fixing methods can also be selected. The needle plate 44 can be installed in the groove formed at the four water outlets on the side of the panel, etc.
[0040] In addition, to facilitate connection with other water supply pipelines, a connector assembly 5 can be added. For example, a connector assembly 5 can be installed at the water inlet hole 101 of the upper housing 1. The connector assembly is connected to the water inlet hole 1 of the upper housing. The connector assembly can be selected from the market according to the needs, such as the universal joint type shown in this example.
[0041] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
