Description

Technical Field

[0001] This utility model relates to a faucet with a built-in water pipe. Background Technology

[0002] As a widely used water supply control device in daily life, the structural design of faucets directly affects the user experience, service life and water quality safety. Traditional faucets usually have a flow channel directly opened inside the shell, from the inlet to the outlet through the valve core seat. The water flow is achieved through the flow channel formed by casting or machining inside the shell. Although this integrated flow channel structure is simple and has a low manufacturing cost, it has exposed many problems in practical applications.

[0003] First, since the internal flow channels of the shell are formed by casting or machining, their inner walls are often relatively rough, which can easily cause water flow turbulence and generate a lot of noise. In addition, scale and impurities are easily accumulated during long-term use, which are difficult to clean and affect the quality of the output water and the stability of the flow rate.

[0004] Secondly, when the flow path between the valve core seat and the outlet is long or the structure is complex, the design of the integrated shell flow channel places high demands on the mold and is difficult to process.

[0005] Therefore, how to stably install water pipes inside the shell has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a faucet with a built-in water pipe that provides guidance for the movement path of water flow by installing a water pipe inside the housing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: it includes a housing, a handle located above the housing, a water flow channel inside the housing, and a valve core located in the water flow channel in conjunction with the handle. The housing has an inlet and an outlet at both ends of the water flow channel, and also includes a water pipe and an aerator located at the outlet. The valve core includes a mounting base. The water pipe is located inside the water flow channel and one end is detachably connected to the mounting base while the other end is detachably connected to the aerator. The bottom of the water pipe abuts against the inner wall of the housing.

[0008] The present invention is further configured such that: the mounting base is provided with a locking block, the inner wall of the housing is provided with a locking slot corresponding to the locking block, the mounting base is fixed with a first connecting member, the aerator includes a fixing base, the fixing base is fixed to the inner wall of the housing and a second connecting member is fixed on the fixing base, the second connecting member and the first connecting member are respectively located on the front and rear sides of the water pipe and are fastened to the water pipe.

[0009] The present invention is further configured such that: the first connector and the second connector have the same shape and size, the first connector includes a plurality of snap-fit ​​segments, each snap-fit ​​segment is connected in sequence and is arranged in the form of a frustum with a rear diameter smaller than the front diameter and has a flow groove inside, and the water pipe is provided with a snap-fit ​​groove corresponding to each snap-fit ​​segment.

[0010] The present invention is further configured such that: an installation sleeve is installed inside the foamer, the installation sleeve includes a guide section near the rear side and a foaming section at the front side, the guide section is cone-shaped with its tip located at the rear side of the guide section and a plurality of first through holes are provided through the guide section, and a plurality of second through holes communicating with the first through holes are provided on the foaming section.

[0011] The present invention is further configured such that: the mounting sleeve is provided with a plurality of positioning plates in the circumferential direction, and the bubbler is provided with a limiting plate protruding between adjacent positioning plates.

[0012] The present invention is further configured such that: the mounting sleeve includes a mounting plate at the top, the bubbler is provided with a mounting cavity for the mounting sleeve to be inserted into, and a support part is provided below the mounting plate, the support part being circumferentially fitted to the bubbler located below the mounting plate.

[0013] The present invention is further configured such that: a filter screen is installed on the front side of the foaming section of the foamer, and the filter screen is provided with a disassembly and assembly part that can be detachably connected to the foamer in the circumferential direction.

[0014] The present invention is further configured such that: the bubbler is provided with an annular disassembly groove in the circumferential direction; the disassembly part is made of a material that is prone to deformation and includes a disassembly plate with the disassembly groove inserted; the disassembly plate includes a plurality of disassembly inserts that are detachably connected to the bubbler and are located between adjacent disassembly inserts.

[0015] The present invention is further configured such that each of the disassembly and assembly blocks is provided with a positioning protrusion for inserting a bubbler, and each positioning protrusion is a hemispherical shape with its opening facing backward.

[0016] By adopting the above technical solution, since the water pipe is located in the water flow channel of the shell and its bottom abuts against the inner wall of the shell, the shell can support the bottom of the water pipe. During the assembly process, both ends of the water pipe can be detachably connected to the mounting base and the aerator, respectively, so that the water pipe can be stably located in the water flow channel and cannot move. Furthermore, since the water entering from the inlet flows through the filter element and flows out from the outlet, the noise generated during the process of flowing through the water pipe is less than that generated by flowing directly through the inner wall of the shell. It can also provide convenience for the shape design of the shell flow channel. There is no need to process irregular pipes. The water flow trajectory can be determined by directly inserting a water pipe of the corresponding shape. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-8 As shown, this utility model discloses a faucet with a built-in water pipe, including a housing 1, a handle 2 located above the housing 1, a water flow channel 11 inside the housing 1, and a valve core 3 located in the water flow channel 11 in conjunction with the handle 2. The housing 1 has an inlet 12 and an outlet 13 at both ends of the water flow channel 11. A cold water pipe and a hot water pipe are located below the valve core 3 on the housing 1. The inlet 12 consists of two pieces located at the bottom of the cold water pipe and the hot water pipe, respectively. By turning the handle 2, the ceramic disc inside the valve core 3 can be moved relative to each other, causing the liquid at the inlet 12 to flow through the flow channel on the valve core 3 to the outlet 13 and thus flow out from the front of the housing 1 (this is prior art and will not be described in detail here; the specific working principle of the valve core 3 can be found in Chinese Patent No. 202223393335.3). It also includes a water pipe 4 and an aerator 5 located at the outlet. The valve core 3 includes a mounting base 31, which is located inside the housing 1 and cannot be rotated. The water pipe 4 is located in the water flow channel 11 and one end is detachably connected to the mounting base 31 by means of fastening or other means, while the other end is detachably connected to the aerator 5 by means of fastening or other means. The aerator 5 is fixed to the housing 1. The bottom of the water pipe 4 abuts against the inner wall of the housing 1. Since the water pipe 4 is located in the water flow channel 11 of the housing 1 and the bottom abuts against the inner wall of the housing 1, the housing 1 can support the bottom of the water pipe 4. During the assembly process, both ends of the water pipe 4 can be detachably connected to the mounting base 31 and the aerator 5 respectively, so that the water pipe 4 can be stably located in the water flow channel 11 and cannot move. In addition, the water entering from the inlet 12 flows through the filter element and flows out from the outlet 13. During the process, the noise generated by the water flowing through the water pipe 4 is smaller than that generated by flowing directly through the inner wall of the housing 1. It can also provide convenience for the shape design of the flow channel of the housing 1. There is no need to process irregular pipes. The water flow trajectory can be determined by directly inserting the water pipe 4 of the corresponding shape.

[0022] The mounting base 31 has a protruding locking block 31, and the inner wall of the housing 1 has a locking slot 14 corresponding to the locking block 31. A first connector 32 is fixed to the mounting base 31 by welding or other means. The aerator 5 includes a fixing base 51, which is fixed to the inner wall of the housing 1. A second connector 52 is fixed to the fixing base 51 by welding or other means. The second connector 52 and the first connector 32 are located on the front and rear sides of the water pipe 4, respectively, and are fastened to the water pipe 4. After the filter element is installed into the housing 1, the locking block 31 on the mounting base 31 will enter the locking slot 14. This design prevents the mounting base 31 from rotating relative to the housing 1, allowing it to remain stably positioned within the housing 1. After the valve core 3 is installed, the water pipe 4 is inserted, enabling the first connector 32 to connect with the mounting base 31. Then, as the aerator 5's fixing seat 51 is installed onto the housing 1, the second connector 52 connects with the front of the water pipe 4, fixing the aerator 5 to the housing 1. This allows the water pipe 4 to remain stably positioned inside the housing 1. When water flows through the water pipe 4, the two ends of the water pipe 4 are stably fixed to the mounting base 31 and the fixing seat 51 by the action of the first connector 32 and the second connector 52.

[0023] The first connector 32 and the second connector 52 are the same in shape and size. The first connector 32 includes several snap-fit ​​segments 321, each snap-fit ​​segment 321 connected in sequence and arranged in the shape of a frustum with a rear diameter smaller than the front diameter, and each having a flow groove 3211 inside. The water pipe 4 is provided with a snap-fit ​​groove 41 corresponding to each snap-fit ​​segment 321. The shape of each snap-fit ​​groove 41 is adapted to the shape of the corresponding snap-fit ​​segment 321. Since the rear diameter of each snap-fit ​​segment 321 is smaller than the front diameter, it can be deformed by the compression of each snap-fit ​​segment 321. Upon reaching the corresponding snap-fit ​​groove 41, after the snap-fit ​​section 321 of the first connector 32 is inserted into the water pipe 4, the rear side of each snap-fit ​​section 321 will abut against the smaller diameter front part of the corresponding snap-fit ​​groove 41 and will not be able to move forward, thereby connecting the first connector 32 to the water pipe 4. When the water flows from the inlet 12 to the outlet 13, the water pressure can exert a forward force on the first connector 32, thereby causing the front side of each snap-fit ​​section 321 to abut against the front side of the adjacent snap-fit ​​groove 41 and will not be able to move backward.

[0024] The foamer 5 has an inner side fitted with a mounting sleeve 53 that is fixedly connected to the fixing base 51 by bolts, adhesive, or other means. The mounting sleeve 53 includes a guide section 531 near the rear and a foaming section 532 at the front. The guide section 531 is conical with its tip located at the rear of the guide section 531, and has several first through holes 5311 penetrating through it. The foaming section 532 has several second through holes 5321 communicating with the first through holes 5311. 1. Because the guide section 531 is conical... The cone-shaped tip is positioned behind the guide section 531, so when the water flows to the outlet 13, it first encounters the cone-shaped tip, which disperses the concentrated water flow impact force to the periphery of the cone surface; 2. The presence of each second through hole 5321 can cut the water flow through each first through hole 5311 into a fine water stream, so that the surface area of ​​the water stream can be increased during the outflow process, making it easier to contact with air and achieve foaming. The foamed water flow can feel fuller, thus saving water, and the water flow impact force is gentle, reducing the occurrence of splashing.

[0025] The mounting sleeve 53 is provided with a plurality of positioning plates 533 circumferentially. The bubbler 5 is provided with limiting plates 54 protruding between adjacent positioning plates 533. After the mounting sleeve 53 is installed into the bubbler 5, the limiting plates 54 on the inner wall of the bubbler 5 can enter between adjacent positioning plates 533, so that the mounting sleeve 53 cannot rotate relative to the bubbler 5, thereby facilitating the fixing of the mounting sleeve 53 and the bubbler 5.

[0026] Preferably, the mounting sleeve 53 includes a top mounting plate 534, and the aerator 5 is provided with a mounting cavity 55 for the mounting sleeve 53 to be inserted into. A support part 56 is provided below the mounting plate 534. The support part 56 is circumferentially fitted with the aerator 5 below the mounting plate 534. Since the mounting plate 534 at the top of the mounting sleeve 53 abuts against the support part 56 of the aerator 5, the mounting sleeve 53 can only be inserted into the mounting cavity 55 from top to bottom, thus providing guidance for the insertion path of the mounting sleeve 53. Furthermore, since the mounting plate 534 is blocked by the support part 56 after assembly, the mounting sleeve 53 cannot rotate relative to the aerator 5 or move upward without the action of external force, thus facilitating the fixing of the mounting sleeve 53 and the aerator 5.

[0027] The aerator 5 is equipped with a filter screen 6 on the front side of the foaming section 532. The filter screen 6 is provided with a disassembly part 61 that can be detachably connected to the aerator 5 by means of snap-fit ​​or other means. Since the filter screen 6 is detachably connected to the aerator 5, impurities in the water flow will be blocked by the filter screen 6 and cannot flow out as they flow toward the outlet 13. Since the disassembly part 61 is detachably connected to the aerator 5, the filter screen 6 with impurities attached can be cleaned after the disassembly part 61 is removed from the aerator 5.

[0028] Preferably, the aerator 5 has a circumferentially formed annular disassembly groove 57. The disassembly part 61 is made of a material that is easily deformable, such as rubber, and includes a disassembly plate 611 into which the disassembly groove 57 is inserted. The disassembly plate 611 includes several disassembly inserts 6111 that are detachably connected to the aerator 5 and deformation grooves 6112 located between adjacent disassembly inserts 6111. By bending each disassembly insert 6111 of the disassembly part 61, it can be inserted into the disassembly groove 57. After each disassembly insert 6111 is detachably connected to the aerator 5, the filter screen 6 can be stably positioned in front of the faucet to filter the water before it flows out.

[0029] Each of the aforementioned disassembly and assembly blocks 6111 is provided with a positioning protrusion 7 for inserting the bubbler 5. Each positioning protrusion 7 is a hemispherical shape with its opening facing backward. When each disassembly and assembly block 6111 is bent and inserted into the disassembly and assembly groove 57, the positioning protrusion 7 on each disassembly and assembly block 6111 will be inserted into the bubbler 5, thereby preventing the disassembly and assembly block 6111 from rotating relative to the bubbler 5. Furthermore, since each disassembly and assembly block 6111 is located in the disassembly and assembly groove 57, it cannot move up and down, thus completing the assembly of the disassembly and assembly part 61 with the bubbler 5. In addition, since each positioning protrusion 7 is a hemispherical shape with its opening facing backward, it is convenient to bend each disassembly and assembly block 6111 to insert the positioning protrusion 7 into the bubbler 5.

[0030] It is also worth noting that a sealing ring (not shown in the figure) can be installed between the fixed base 51, the mounting sleeve 53, the filter screen 6 and the aerator 5 to improve the sealing performance.

[0031] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
