Description

Technical Field

[0001] This invention relates to the field of fluid switch technology, and more particularly to a faucet. Background Technology

[0002] Tap water is water that meets national drinking water standards and is used for daily life and production after being purified and disinfected at water treatment plants. Most tap water disinfection uses chlorination, primarily to prevent waterborne diseases. Although existing tap water disinfection processes have relatively sophisticated technology and equipment, analysis and research of theoretical data have revealed certain drawbacks to using chlorination for tap water disinfection.

[0003] With modern people's increasing demands for quality of life, users generally prefer purified water, which has higher safety and hygiene standards, when it comes to drinking water. However, most existing faucets are still unable to provide water for different purposes (such as cleaning and drinking) simultaneously due to structural limitations. Other faucets that can supply both purified and tap water at the same time have the problem of mixing, which can contaminate the purified water. This forces users to install additional drinking water faucets or separate drinking water dispensers to obtain safe drinking water.

[0004] Based on this, relevant technical personnel are still dedicated to designing a faucet to at least partially overcome the shortcomings of existing technology. Summary of the Invention

[0041] An exemplary embodiment of a faucet according to the present invention will now be described in detail with reference to the accompanying drawings. The drawings are provided to illustrate various embodiments of the invention; however, the drawings are not necessarily drawn to the dimensions of the specific embodiments, and certain features may be enlarged, removed, or partially cut to better illustrate and explain the disclosure of the invention. Some components in the drawings may be repositioned according to actual needs without affecting the technical effect. The phrase "in the drawings" or similar expressions appearing in the specification do not necessarily refer to all drawings or examples.

[0042] Certain directional terms used in the description of the accompanying drawings below, such as “inner,” “outer,” “upper,” “lower,” and other directional terms, shall be understood to have their normal meaning and refer to those directions involved when normally viewing the drawings. Unless otherwise specified, the directional terms used in this specification are generally in accordance with the conventional directions understood by those skilled in the art.

[0043] The terms “first,” “first,” “second,” “second,” and similar terms used in this invention do not indicate any order, quantity, or importance, but are used to distinguish one component from other components.

[0044] like Figure 1-18 As shown, the present invention provides a faucet 1, which integrates a tap water pipe 30 and a purified water pipe 40, that is, the faucet 1 can be used as a dual-outlet faucet 1, which can be adjusted to tap water mode or purified water mode according to the user's needs.

[0045] Specific reference Figure 1and Figure 2 The faucet 1 includes a housing 10, a bracket, a tap water pipe 30, and a purified water pipe 40. The tap water pipe 30 includes a first pipe body 300, and the purified water pipe 40 includes a second pipe body 400. The housing 10 is typically constructed as a pipe fitting with a cavity, including a main pipe 100 and a branch pipe 102. The main pipe 100 is typically mounted upright on the platform where the faucet is installed. The main pipe 100 primarily houses the body 60 of various fluid lines and guides the flow path. The branch pipe 102 is located radially to the main pipe 100 and primarily houses the switching valve assembly 80 (which can be considered as including the valve seat 800, valve core 802, and valve cover 804 detailed below; this is for ease of description and does not imply that the above structure must remain integral or be installed as a single unit). Figure 3 (As shown) and install the handle.

[0046] like Figure 3 As shown, the bracket is installed on the housing 10, particularly the main pipe 100 of the housing 10, and is pivotable relative to the housing 10, that is, it rotates around the housing 10 as an axis. This is mainly achieved through the engagement of the flange 203 with the housing 10, which will be described in detail below. The bracket is mainly used to adjust the position of the tap water or purified water relative to the basin / sink according to the user's needs, or to switch positions between different sinks for user convenience. Moreover, the first pipe 300 can be removed from the bracket at any time and used by the user at different angles and positions. Obviously, this greatly facilitates the user and provides ample possibilities to meet various user needs. Furthermore, the first pipe body 300 for tap water and the second pipe body 400 for purified water can be used separately without interfering with each other. The outlet end 400a of the second pipe body 400 is independently arranged on the support and is physically isolated from the outlet end 300a of the first pipe body 300. Therefore, the outlet ends 300a and 400a of tap water and purified water will not be contaminated by tap water because they are fixedly arranged on the same structural component or the outlet end 400a of purified water is arranged in the outlet area of ​​tap water.

[0047] like Figures 7 to 10As shown, the bracket preferably includes an upper bracket 200 and a lower bracket 201. The upper bracket 200 can be engaged with the lower bracket 201 to form an internal receiving space, which is mainly used to accommodate the purified water pipe 40, specifically the second pipe body 400 of the purified water pipe 40 (which can also be called a folding pipe in a faucet 1 with a folding water path). The second pipe body 400 is mainly used to guide the purified water, after folding, to the outlet end of the faucet 1. The outlet end 400a of the second pipe body 400 is embedded in the lower bracket 201 and partially extends out of the lower bracket 201. This split bracket structure, including the upper bracket 200 and the lower bracket 201, facilitates installation and maintenance by the user. If the second pipe body 400 of the purified water pipe 40 wears out, this assembled bracket structure makes it easy to replace the second pipe body 400.

[0048] The aforementioned faucet 1 also includes a deformable tube 50, within which a first pipe body 300, as mentioned above, is inserted. The first pipe body 300 is primarily used to supply the user with the mixed water (cold and hot water) that has been mixed by the valve core 802. As described below, refer to... Figures 2 to 3 The first pipe body 300 is connected to the tap water outlet pipe 304. The first pipe body 300 passes through the bracket from one end of the bracket engaging housing 10. At the position corresponding to the outlet end 300a of the first pipe body 300, the upper bracket 200 and the lower bracket 201 together form a receiving hole 202, and the outlet end 300a of the first pipe body 300 can be detachably engaged to the receiving hole 202. That is, the first pipe body 300 can be placed on the bracket for use by engaging its outlet end 300a with the bracket, or the outlet end 300a of the first pipe body 300 can be detached from the bracket and used in a suitable position. In fact, the outlet end 300a of the first pipe body 300 is inserted into the grip part 502 for the user to hold. After the tap water flows out from the outlet end 300a, it is controlled by the switch valve core 802 on the grip part 502 and finally flows out for the user through the guide channel or conduit provided in the grip part 502. Figure 2 , Figure 5 As shown, the grip 502 is generally cylindrical, and its bottom can be designed to taper or be stepped (with a smaller diameter at the step) to facilitate insertion into the receiving hole 202 of the bracket. Figure 18As shown, a magnetic ring 502a is disposed inside the gripping part 502. The magnetic ring 502a is located at the bottom of the gripping part 502 engaging with the receiving hole 202 and abuts against the inner wall of the gripping part 502. A magnet 208 is disposed inside the bracket and is arranged at the position abutting against the wall of the receiving hole 202, so that after the gripping part 502 is engaged with the receiving hole 202, the magnet 208 and the magnetic ring 502a attract each other through a magnetic effect, thereby better fixing the gripping part 502. Of course, those skilled in the art can also conceive of other structures that are beneficial to fixing the gripping part 502. These structures can be mechanical, electromagnetic, etc., but these modifications to this embodiment all fall within the protection scope of this invention.

[0049] The deformable tube 50 has a built-in support tube 500 at least at one end of the support engaging the housing 10 to support and define the shape of the deformable tube 50. Optionally or preferably, in one embodiment, as Figure 2 As shown, the deformable tube 50 contains two support tubes 500. One support tube 500 is placed at one end of the hose near the bracket engaging housing 10, while the other support tube 500 is placed at one end of the hose engaging grip 502. The end of the grip 502 is stepped and detachably engages the receiving hole 202 of the bracket. The first tube 300 passes through the deformable tube 50 and extends to the grip 502. The deformable tube 50 can be bent to different angles according to the user's needs. The user can continuously change the position of the deformable tube 50 so that the discharged fluid can reach various positions in the sink or basin, making it convenient for the user to clean various positions in the sink / basin. The faucet 1 of the present invention, especially the first tube 300 for discharging tap water, is no longer limited to use in a predetermined area, such as a fixed position or a position that moves along an arc formed by rotating around the faucet housing 10 as an axis. It can be bent and deformed according to the user's needs to reach the desired position.

[0050] In a preferred embodiment, refer to Figures 7 to 10 The bracket formed by the upper bracket 200 and the lower bracket 201 can be considered as a long and slender box. For aesthetic and functional reasons, the middle of the bracket is hollowed out. This allows for positional restriction of the second tube 400 of the pure water pipe 40. Of course, the shape of the bracket is not limited to this; other brackets that can achieve the functions of this invention fall within the scope of this invention.

[0051] The flange 203 described above is located at the opposite end of the upper support 200 at the outlet end (i.e., the end where the support engages with the housing 10). The flange 203 extends toward the housing 10 and is configured to restrict the movement of the second pipe 400. Specifically, the flange 203 of the upper support 200 can be configured as annular, with a notch 204 on its circumferential surface extending axially along the flange 203. The lower support 201 has a semi-protrusion 206 extending from the bottom surface of the lower support 201 toward the housing 10, and the semi-protrusion 206 can engage with the notch 204 of the upper support 200 to form a complete circular flange 203. The semi-protrusion 206 is provided with a stepped portion, which extends partially or entirely along the length of the semi-protrusion 206. At the location where the semi-protrusion 206 mates with the notch 204, the stepped portion abuts against the edge of the notch 204, thereby sealing the notch 204 and forming a complete circular flange 203. The semi-protrusion 206 is generally a plate-like piece with an arcuate curve, the curve forming a concave channel. The upper support 200 also has another semi-protrusion 205 within the area defined by its flange 203, which also extends towards the housing 10. The two semi-protrusions 205 and 206 are similar in shape and structure. When the upper support 200 and lower support 201 are engaged, the two semi-protrusions 205 and 206 together form a limiting channel 207. The lower support 201 also has an opening communicating with the limiting channel 207, through which the second pipe body 400 of the pure water pipe 40 can pass. When the upper support 200 and the lower support 201 are engaged, the second tube 400 is clamped by two semi-protrusions 205 and 206, thereby restricting the movement of the second tube 400 relative to the support.

[0052] In another preferred embodiment, the flange 203 is a complete annular flange 203 and is formed only on the upper support 200 or the lower support 201. When the flange 203 is formed only on the upper support 200, the limiting channel 207 originally formed by the two semi-protrusions 205, 206 is formed on the inner side of the flange 203 near the lower support 201. This limiting channel 207 extends axially toward the housing 10 along the flange 203 and restricts the movement of the second tube 400 of pure water. The shape and / or structure of this limiting channel 207 is the same as or similar to the aforementioned limiting channel 207 formed by the two semi-protrusions 205, 206. The case where the flange 203 is only provided on the lower support 201 will not be described in detail here, because those skilled in the art can be inspired by the disclosure of this invention and conceive of how to provide the flange 203 on the lower support 201.

[0053] Specifically, such as Figures 15 to 17As shown, a body 60 is housed within the main pipe 100 of the housing 10. The body 60 includes a pipe connector 600 and a fluid inlet 601. The pipe connector 600 includes a first pipe connector 600a and a second pipe connector 600b, which are respectively connected to a tap water pipe 30 and a purified water pipe 40. The pipe connector 600 communicates with the fluid inlet 601. The body 60 has an inwardly inclined seat 602, on which the fluid inlet 601 is disposed. Specifically, the seat 602 is formed as an inclined surface that slopes inward toward the body 60. The seat 602 can be configured to seat a valve seat 800 thereon, which communicates with the fluid inlet 601. A sealing element is also provided between the seat 602 of the body 60 and the valve seat 800 to form a seal around the fluid inlet 601 when the body 60 and the valve seat 800 are engaged, thereby preventing fluid leakage. A clamping element 90 (e.g., a threaded clamping ring of a branch pipe 102 of the housing 10) clamps the valve seat 800 to ensure a tight fit with the body 60. The valve core 802 engages with the valve seat 800 and is confined within the branch pipe 102 of the housing 10 after the valve cover 804 engages with the clamping element 90. The valve core 802 communicates with the valve seat 800, and its stem engages with a handle, allowing the user to control the flow of fluids, including tap water and purified water.

[0054] See you again Figure 17 The main body 60 has a locking block 603 at its top (that is, on the side along the axial direction near the support), such as Figure 17 As shown, the locking block 603 is exemplaryly constructed in a stepped shape. The locking block 603 is primarily a protrusion extending axially from the body 60. Furthermore, the locking block 603 is also arranged radially from the body 60 to extend at least partially beyond the inclined surface of the seat 602. Specifically, the circumferential surface of the locking block 603 is closer to the inner wall of the housing 10 than the inclined surface of the seat 602. A latch 104 is provided inside the housing 10, which includes the main pipe 100 and the branch pipe 102, as mentioned above. The latch 104 is specifically located at the transition between the main pipe 100 and the branch pipe 102 and is arranged axially along the main pipe 100. The latch 104 and the locking block 603 engage with each other when the body 60 is installed into the housing 10, thereby restricting the rotation of the body 60 relative to the housing 10 for better positioning of the body 60.

[0055] For example Figure 17As shown, the main body 60 also has a stop 604 at the bottom end of the seat 602 (that is, the end of the seat 602 away from the bracket). The stop 604 is specifically constructed to form an arc-shaped protrusion extending along the edge of the seat 602. After the clamping member 90 mentioned above engages with the branch pipe 102 and abuts against the inclined surface of the seat 602, the protrusion and the locking block 603 together restrict the movement of the main body 60 within the housing 10, such as rotation relative to the housing 10 or axial (upward and downward) movement within the housing 10.

[0056] The fluid inlets 601 mentioned above are mainly distributed on the inclined seat 602 of the body 60. These fluid inlets 601 include a first inlet 601a and a first outlet 601b for tap water, and a second inlet 601c and a second outlet 601d for purified water. The first inlet 601a and the first outlet 601b are respectively configured to connect to the inlet pipe 302 and outlet pipe 304 of the tap water pipe 30, while the second inlet 601c and the second outlet 601d are respectively configured to connect to the inlet pipe 402 and outlet pipe 404 of the purified water pipe 40. The first inlet 601a, together with the third inlet 601e described below, can be used to conduct cold water and hot water respectively.

[0057] like Figure 14 and Figure 17 As shown, the pipe connector 600 includes a first pipe connector 600a and a second pipe connector 600b. The first pipe connector 600a extends axially away from the support along the housing 10, while the second pipe connector 600b extends axially towards the support along the housing 10. Specifically, as shown, the first pipe connector 600a extends downwards, while the second pipe connector 600b extends upwards. The first pipe connector 600a connects to the inlet pipe 302 of the tap water pipe 30 and the inlet pipe 402 and outlet pipe 404 of the purified water pipe 40, respectively. The second pipe connector 600b connects to the outlet pipe 304 of the tap water pipe 30, and the outlet pipe 304 connects to the first pipe 300. The second pipe 400 is configured at its end opposite to the outlet end 400a to connect to the purified water outlet pipe 404. Typically, the connection between the pipes is achieved through a pressure-bearing plug joint.

[0058] In the above text, such as Figures 1 to 3As shown, the purified water pipe 40 with the outlet pipe 404 constitutes a purified water reversal path. That is, after the purified water is controlled by the valve core 802 (e.g., to open the purified water path) and passes through the body 60, it is then discharged through the body 60. The discharged purified water is then guided to the second pipe body 400 via the adapter 406. The adapter 406 is constructed to introduce purified water into the body 60, receive purified water discharged from the body 60, and finally supply purified water to the outlet end 400a of the second pipe body 400, thus realizing the reversal of purified water in the entire flow path. The adapter 406 connects to a water purifier that supplies pure water (typically, the water source for the purifier is provided by the tap water inlet pipe 302, such as the branch pipe 102 of the cold water inlet pipe 302), and also connects to the inlet pipe 402 that supplies pure water to the main body 60. The adapter 406 also connects to the outlet pipe 404 that discharges pure water from the main body 60, and further connects to the second pipe 400 that finally supplies pure water to the user.

[0059] In faucet 1, which uses a reversible water path, such as Figure 3 , Figure 4 Figure 17 As shown, the body 60 also includes a tube limiting member 605, which extends through the body 60 along the axial direction of the housing 10 so that the second tube 400 passes through and is restricted to move within the tube limiting member 605. Since the second tube 400 needs to rotate with the support, it will move within the housing 10. During this time, the second tube 400 may continuously rub against the housing 10 or the body 60 and move within a large range within the housing 10. To avoid this friction and to restrict the movement of the second tube 400 to a local area, the tube limiting member 605 is provided on the body 60. Specifically, the tube limiting member 605 is constructed as a hollow tube and is axially parallel to the tube connector 600.

[0060] In faucet 1, which does not employ a reversible water path, such as Figure 16 , Figure 17 As shown, the fluid inlet 601 includes a first inlet 601a and a first outlet 601b for tap water, and a second inlet 601c and a second outlet 601d for purified water. The first inlet 601a and the first outlet 601b are respectively configured to connect to the inlet pipe 302 and the outlet pipe 304 of the tap water pipe 30. The second inlet 601c and the second outlet 601d are respectively configured to connect to the inlet pipe 402 and the second pipe body 400 of the purified water pipe 40. The third inlet 601e, as described below, together with the first inlet 601a, can be used to conduct cold water and hot water respectively.

[0061] Reference Figure 14 , Figures 16 to 17The pipe connector 600 includes a first pipe connector 600a and a second pipe connector 600b. The first pipe connector 600a extends axially away from the support along the housing 10, and the second pipe connector 600b extends axially towards the support along the housing 10. The first pipe connector 600a connects to the inlet pipe 302 of the tap water pipe 30 and the inlet pipe 402 of the purified water pipe 40, respectively. The second pipe connector 600b connects to the outlet pipe 304 of the tap water pipe 30 and the second pipe body 400 of the purified water pipe 40, wherein the outlet pipe 304 connects to the first pipe body 300. The aforementioned pipe connector 600 is typically threadedly connected to each water supply pipe.

[0062] The second tube 400 is configured to pivot around the housing 10 with the support. Specifically, the second tube 400 can be configured as an elastic element that meets the requirement of elongation when the second tube 400 pivots around the housing 10 to its farthest point with the support, and meets the requirement that the second tube 400 itself does not bend excessively and rub against the inner wall of the housing 10 when the second tube 400 returns to the starting point with the support.

[0063] Or, such as Figures 5 to 6 As shown, the second tube 400 can be configured to be pulled out relative to the body 60, similar to piston movement. When the second tube 400 is at the origin of rotation (the support is not rotating relative to the housing 10), the second tube 400 is partially housed within the body 60. When the second tube 400 is at the end of rotation (the support is rotated to its maximum angle relative to the housing 10), a portion of the second tube 400 housed within the body 60 can be pulled out of the body 60. When the support rotates back to the origin of rotation, this portion of the second tube 400 that was pulled out of the body 60 retracts back into the body 60. During this process, a good seal is maintained between the second tube 400 and the tube connector 600 of the body 60 to prevent possible leakage.

[0064] In the above-mentioned faucet 1, which uses a reversible water path and a non-reversible water path, such as Figures 1 to 3 As shown, the tap water inlet pipe 302 includes a cold water inlet pipe and a hot water inlet pipe. The fluid inlet 601 of the body 60 also includes a third inlet 601e. The third inlet 601e and the first inlet 601a can be respectively configured to connect the aforementioned cold water inlet pipe and hot water inlet pipe. Both the cold water inlet pipe and the hot water inlet pipe are connected to the first pipe body connector 600a.

[0065] In addition, see Figures 11 to 13The flange 203 has an axially extending protrusion 203a at its end facing the housing 10, and the inner circumference of the housing 10 has a radially extending protrusion 106. The protrusion 203a cooperates with the protrusion 106 to limit the rotation range of the bracket relative to the housing 10. Specifically, after the flange 203 is inserted into the housing 10, the protrusion 203a rotates relative to the housing 10 along with the flange 203 of the bracket until the protrusion 203a abuts against the protrusion 106 of the housing 10, at which point the rotation of the bracket relative to the housing 10 stops. At this point, the bracket has just rotated 180° relative to the housing 10 from the starting point of rotation to the ending point of rotation. Of course, those skilled in the art will understand that this angle is merely exemplary and is not intended to limit the invention.

[0066] Preferably, such as Figure 11 As shown, the faucet 1 also includes a wear-resistant sleeve 70, which is located between the flange 203 and the housing 10. The wear-resistant sleeve 70 is fitted around the outer periphery of the flange 203 and has a radially extending periphery. After the flange 203 with the wear-resistant sleeve 70 is inserted into the housing 10, its periphery abuts against the top edge of the housing 10 to prevent the wear-resistant sleeve 70 from falling into the housing 10. The wear-resistant sleeve 70 has a circumferential protrusion 700, and the housing 10 has a groove 108 at the end of the engaging bracket. The protrusion 700 engages with the groove 108 to restrict the rotation of the wear-resistant sleeve 70 relative to the housing 10. The protrusion 700 can be a ridge, rib, or block. Figure 11 In the embodiment shown, there may be two protrusions 700. When the wear-resistant sleeve 70 is engaged with the housing 10, the two protrusions 700 abut against the inner wall of the groove 108 respectively, thereby restricting the rotation of the wear-resistant sleeve 70 relative to the housing 10. Moreover, during the relative rotation of the two, the rotational friction mainly occurs between the wear-resistant sleeve 70 and the housing 10, thus avoiding wear of the bracket.

[0067] Furthermore, the valve core 802 of the aforementioned faucet 1, used to separately open and close tap water and purified water, includes a valve body, a valve seat, a valve stem, a moving valve plate, a stationary valve plate, and a rotating seat. The rotating seat is located inside the valve body, and a linkage component, a moving valve plate, and a stationary valve plate are sequentially stacked below it. The valve body is engaged with the valve seat 800. The valve stem extends from the rotating seat out of the valve body and is controllably connected to the rotating seat. A linkage component can be installed below the rotating seat, which can actuate the valve plate as the valve stem is driven. The valve plate includes a moving valve plate and a stationary valve plate. The moving valve plate includes a mixing chamber and a flow guide groove, which communicates with the opening to allow purified water to enter. The stationary valve plate includes a first inlet hole and a second inlet hole for introducing cold water and hot water respectively, a tap water outlet hole for discharging mixed water, and a purified water outlet hole for discharging purified water. The valve stem can rotate relative to the rotating seat, and the linkage connector further drives the moving valve plate to translate or rotate relative to the stationary valve plate. During the movement of the moving valve plate relative to the stationary valve plate, tap water is opened when the first inlet hole and / or the second inlet hole are connected to the mixing chamber, and purified water is opened when the flow guide groove and the fluid passage hole are connected. Tap water and purified water have their own independent flow paths in the valve core 802, preventing cross-contamination and ensuring that the purified water always meets drinking water standards.
