Description

Technical Field

[0001] The utility model relates to the field of sanitary wares, and particularly to a single - handle pipe - passing faucet structure. Background Art

[0002] A faucet is an inseparable household appliance in daily life, which can be divided into several types such as single - handle type and double - handle type. Among them, the single - handle faucet is often designed to be able to connect two pipes of cold and hot water at the same time, and the mixing and switching are carried out through a valve core, which is particularly convenient to use. However, the outlet pipe of the single - handle faucet is in an oblique or bent shape, which is beneficial to extending the water outlet nozzle outward to meet the use requirements. However, the oblique or bent pipe needs to have sufficient bearing capacity to resist the deformation caused by gravity. Generally, it needs to be designed as a hard metal material to achieve a better installation effect and extension effect. Based on the above requirements, when designing the single - handle faucet, due to the limitation of the hard (metal) outlet pipe, the hard (metal) outlet pipe is often arranged upward in the upper part of the faucet shell. Therefore, the designed faucet structure generally has a relatively single form. Moreover, the hard (metal) outlet pipe not only needs to meet the water - passing requirements (there are special standards and requirements for the metal material), but also needs to be designed into a reasonable extended form, resulting in a relatively high product cost and complex production.

[0003] If a plastic or rubber pipe is directly used, it often presents an uneven and awkward bent shape, which is very unsightly. At the same time, the plastic or rubber pipe does not have enough strength to adapt to the assembly. If the conventional quick - insertion form is used for design and insertion, due to the insufficient hardness of the material, it is often impossible to directly insert it externally to achieve a good insertion and sealing effect. Therefore, it affects the aesthetics and is not easy to install. Content of the Utility Model

[0004] The utility model aims to provide a single - handle pipe - passing faucet structure that can use a plastic outlet pipe, meet the metal appearance, and is easy and firm to assemble.

[0005] To achieve the above - mentioned purpose, the utility model provides a single - handle pipe - passing faucet structure, which includes a faucet shell with a lateral water outlet nozzle and a water outlet elbow. A set of valve seat, valve core and switch handle are assembled in the middle of the faucet shell in a conducting manner. The valve seat is fixed in the faucet shell. The valve seat is provided with at least one water inlet through - hole and one water outlet through - hole that are isolated from each other. The water outlet through - hole includes a longitudinal water inlet end and an installation end that is obliquely outwardly conducting. One end of a water outlet elbow is provided with an outer wall flange. The end of the water outlet elbow is inserted into the installation end of the water outlet through - hole of the valve seat through the lateral water outlet nozzle. Additionally, a fixed bushing is provided with an arc - shaped limiting groove. The fixed bushing is clamped on the valve seat, and the arc - shaped limiting groove on it tightly clamps the end of the water outlet elbow on the installation end of the valve seat. The valve core is fixed to the valve seat, the water outlet hole on it is in communication with the water outlet through - hole, and the water inlet hole on it is in one - to - one communication with at least one water inlet through - hole. A switch handle is assembled on the valve core to achieve switching or mixing adjustment.

[0005]

[0006] Furthermore, a protruding limiting flange is provided on the inner wall of the faucet housing, and a corresponding limiting seat is provided on the valve core seat. The valve core seat is limited by the limiting seat on the limiting flange, and the installation end of its upper water outlet through hole faces the water outlet nozzle channel.

[0007] Furthermore, a further positioning structure is provided between the valve core seat and the limiting flange. The positioning structure includes positioning ribs on the valve core seat and positioning holes correspondingly arranged on the limiting flange. When the valve core seat is limited on the limiting flange, the positioning ribs are inserted into the positioning holes to ensure that the installation end of the valve core seat is fixedly facing the water outlet nozzle channel, so as to be quickly inserted by the water outlet elbow.

[0008] Furthermore, when the end of the water outlet elbow is inserted into the installation end of the water outlet through hole of the valve core seat through the lateral water outlet nozzle, a part or all of the outer wall flange at the end is exposed outside the installation end of the water outlet through hole; when the fixing bushing is clamped on the valve core seat, the arc-shaped limiting groove on it buckles on the pipe diameter part of the water outlet elbow, and the outer wall flange is buckled inside the fixing bushing to ensure that the end of the water outlet elbow is fixed inside the installation end of the water outlet through hole, so that the water outlet elbow cannot be separated from the valve core seat.

[0009] Furthermore, the installation end of the water outlet through hole presents a trumpet shape or an open shape, which is easy for the end of the water outlet elbow to be quickly inserted into the installation end of the water outlet through hole.

[0010] Furthermore, the fixing bushing is provided with at least one hook extending downward, the valve core seat is provided with a fixing plate, and at least one hook groove is provided at the corresponding position of the fixing plate. The hooks are just buckled into the hook grooves one by one to ensure that the fixing bushing is clamped on the valve core seat, and the arc-shaped limiting groove of the fixing bushing is just located outside the installation end of the water outlet through hole to realize the fastening of the water outlet elbow.

[0011] Furthermore, the water outlet elbow is a plastic elbow, a rubber elbow or a silicone elbow.

[0012] The utility model provides a single-handle pipe-passing faucet structure. Through the cooperation of the valve core seat and the fixing bushing, the water outlet elbow inserted from the lateral water outlet nozzle is buckled and fixed in the valve core seat, so that the water path is conducted through the valve core seat and the valve core. The on-off of the water flow and the mixing of cold and hot water are controlled by the switch handle. The structure design is simple and easy to assemble. Especially when the water outlet elbow is made of soft materials such as plastic or rubber, the water outlet elbow does not have enough strength to complete the insertion into the water path and the sealing and fixing effect alone. Therefore, by adopting this structure, the installation effect of the water outlet elbow in the water outlet through hole of the valve core seat can be well realized through the buckling of the fixing bushing, making the application field of this product wider.

[0013] Furthermore, the installation end of the water outlet through hole is designed to be an open or trumpet structure, which is more conducive to the soft water outlet elbow being easily inserted into the installation end.

[0014] Since the faucet housing and the water outlet nozzle do not pass water, a zinc alloy material can be selected. The whole set of products is assembled separately, with a simple structure, reducing the production difficulty while improving the quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0021] As Figures 1 - 7 shown, a single-handle pipe-passing faucet structure includes a faucet housing 1 with a lateral water outlet nozzle 21 and a water outlet elbow 7. A set of valve seat 3, valve core 5 and switch handle 6 are assembled in the middle of the faucet housing 1 in a conductive manner.

[0022] As Figure 3As shown, the valve core seat 3 is fixed inside the faucet housing 1. The valve core seat 3 is provided with two mutually isolated water inlet through holes 31 and one water outlet through hole 32. The water outlet through hole 32 includes a longitudinal water inlet end 322 and an installation end 321 that conducts obliquely outwards. In this embodiment, the water outlet through hole 32 is designed in a corner shape, that is, the longitudinal water inlet end 322 and the installation end 321 present an acute-angle corner shape. Through the corner design, a better water path bending is achieved, which is beneficial to meeting the water passing effect and ensuring the installation effect of the water outlet elbow 7 within the relatively small space of the valve core seat 3. A protruding limit flange 22 is provided on the inner wall of the faucet housing 1. The valve core seat 3 is provided with a corresponding limit seat 35. The valve core seat 3 is limited by the limit seat 35 to the limit flange 22, and the installation end 321 of its water outlet through hole 32 faces the channel of the water outlet nozzle 21. In this embodiment, the limit seat 35 is designed as two annular flanges 351, and an annular groove 352 is formed between the two annular flanges 351. A sealing ring 353 is sleeved in the annular groove 352 to ensure the sealing and limiting effect of the valve core seat 3 within the faucet housing 1.

[0023] An outer wall flange 711 is provided at one end 71 of a water outlet elbow 7. The end 71 of the water outlet elbow 7 is inserted into the installation end 321 of the water outlet through hole 32 of the valve core seat 3 through the side water outlet nozzle 21.

[0024] A further positioning structure is provided between the valve core seat 3 and the limit flange 22. The positioning structure includes a positioning rib 33 of the valve core seat 3 and a positioning hole 221 provided correspondingly on the limit flange 22. When the valve core seat 3 is limited to the limit flange 22, the positioning rib 33 is inserted into the positioning hole 221 to ensure that the installation end 321 of the valve core seat 3 is fixed and faces the channel of the water outlet nozzle 21, so as to be quickly inserted by the water outlet elbow 7.

[0025] In this embodiment, when the end 71 of the water outlet elbow 7 is inserted into the installation end 321 of the water outlet through hole 32 of the valve core seat 3 through the side water outlet nozzle 21, the outer wall flange 711 of the end 71 is partially exposed outside the installation end 321 of the water outlet through hole 32.

[0026] There is also a fixed bushing 4 with an arc-shaped limiting groove 41. The fixed bushing 4 is clamped to the valve core seat 3. When the fixed bushing 4 is clamped to the valve core seat 3, the arc-shaped limiting groove 41 thereon buckles on the diameter part 72 of the water outlet elbow 7, and the outer wall flange 711 is buckled into the fixed bushing 4, ensuring that the end 71 of the water outlet elbow 7 is fixed within the installation end 321 of the water outlet through hole 32, so that the water outlet elbow 7 cannot be detached from the valve core seat 3. The fixed bushing 4 is provided with two hook buckles 42 extending downward. The valve core seat 3 is provided with a fixing plate 34, and two hook grooves 341 are provided at corresponding positions of the fixing plate 34. The hook buckles 42 are exactly buckled into the hook grooves 341 one by one, ensuring that the fixed bushing 4 is clamped to the valve core seat 3, and the arc-shaped limiting groove 41 of the fixed bushing 4 is exactly located outside the installation end 321 of the water outlet through hole 32, realizing the tight fastening of the water outlet elbow 7.

[0027] As Figure 6 shown, in this embodiment, the installation end 321 of the water outlet through hole 32 presents an open shape, which is easy for the end 71 of the water outlet elbow 7 made of plastic or rubber to be quickly inserted into the installation end 321 of the water outlet through hole 32. As Figure 5 shown, when the water outlet elbow 7 is inserted into the installation end 321, the outer wall flange 711 of the end 71 is partially exposed outside the installation end 321 of the water outlet through hole 32; due to the open shape of the installation end 321, the end 71 of the water outlet elbow 7 can be easily inserted into the installation end 321, and this design does not require the water outlet elbow 7 to achieve sealing and stability effects during insertion. Instead, the water outlet elbow 7 is buckled and fixed within the water outlet through hole 32 by the arc-shaped limiting groove 41 of the fixed bushing 4, making the installation particularly simple, and the stability and sealing performance are guaranteed. Therefore, there are fewer restrictions on the material of the water outlet elbow 7, greatly increasing the scope of use of this patent. In some embodiments, the installation end 321 of the water outlet through hole 32 can also be designed in a large opening angle such as a flared shape. In some embodiments, the arc-shaped limiting groove 41 of the fixed bushing 4 only needs to buckle a part of the outer wall flange 711 of the end 71 of the water outlet elbow 7, without overall inclusion.

[0028] The valve core 5 is fixed to the valve core seat 3. In this embodiment, the valve core 5 is provided with two water inlet holes 52. The water outlet hole 51 of the valve core 5 is communicated with the water outlet through hole 32 of the valve core seat 3, and the water inlet holes 52 of the valve core 5 are respectively communicated with the two water inlet through holes 31 of the valve core seat 3; further, two water inlet pipes 8 are respectively assembled in the two water inlet through holes 31 of the valve core seat 3, and the two water inlet pipes 8 are respectively connected to the external cold and hot water. In actual application, this faucet product is assembled on the use tabletop through a mounting screw 91 and a fitting 92.

[0029] A valve core pressing cap 93 is screwed in the faucet housing 1 to tightly fix the valve core 5 above the valve core seat 3; a switch handle 6 is assembled on the valve core 5 to achieve on-off and / or mixing adjustment.

[0030] At the outer end portion 71 of the water outlet nozzle 21, an aerator 94 is generally installed, which cooperates with the water outlet elbow 7 to form a better use effect.

[0031] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
