Description

Structure of faucet

Technical Field

The invention relates to a faucet, in particular to a faucet structure.

Background

Many water taps made of copper materials and other metals not only have high production and manufacturing costs, but also are easy to generate lead precipitation, therefore, more and more faucets use the built-in plastic water outlet pipe and the plastic valve component as the water passing part to avoid the water pollution caused by lead, however, in order to make the internal outlet pipe smoothly connect with the valve seat installed in the body part of the faucet shell, the outlet pipe is usually bent, so that the faucet shell must provide a relatively large assembly space, and a large lead angle structure must be formed at the connection part of the body part of the faucet shell and the water nozzle part to allow the outlet pipe and the valve assembly to be smoothly installed and accommodated therein, due to the structural design, the die sinking and the material cost of the faucet shell are high, the integral appearance and the size are limited, and the texture and the aesthetic feeling of the appearance of a product are difficult to improve.

Chinese grant publication No. CN203384565U utility model discloses a fixed knot of outlet pipe joint and outlet pipe constructs, utilize to install a return bend between the disk seat of outlet pipe and control valve subassembly, thereby shared space when reducing the outlet pipe connection, but can clearly see, install the one end that the return bend that is used for linking up the outlet pipe in the disk seat, its opening direction is not up, but an oblique extension angle, in order to match the outlet pipe molding of crooked molding, therefore, the tap casing that is used for installing and holds outlet pipe and control valve subassembly still must provide great assembly space, and the body position of tap casing still has great lead angle molding with the continuous department of water injection well choke position, improve very limitedly to the known art.

The patent application of the invention with the Chinese application publication number CN110345278A discloses a water outlet device, wherein a joint is used for connecting the bottom of a valve seat of a valve component with a water outlet pipe, so that the effects of small assembly space and small appearance limitation can be realized compared with the utility model. However, the joint is directly connected to the bottom of the valve seat, which means that the joint occupies the bottom space of the valve seat, and the valve seat is affected when assembling the cold water inlet pipe and the hot water inlet pipe, which is not favorable for assembling the water inlet pipe, and at the same time, the joint provides the end for connecting the water outlet pipe, which is also limited by the structure of the valve seat, and cannot extend upwards to the junction of the first space and the second space, so that the water outlet pipe still has to form a bending structure shape to smoothly extend from the second space to the first space to be connected with the joint, however, the bent water outlet pipe structure not only has to be installed more difficultly, but also has to provide a larger assembling space inside the housing, and provides a larger guide angle structure at the junction of the first space and the second space of the housing, so as to allow the water outlet pipe to be installed and accommodated smoothly therein, in addition, the bent outlet pipe is usually limited to be a circular pipe due to various reasons, such as whether the outlet pipe is easy to butt joint, and is difficult to be designed into a flat structure, so that when the outlet pipe needs to extend to the first space, the occupied space cannot be reduced, and overall, there is still a great improvement space for reducing the assembly space inside the housing.

In addition, since the outlet pipe of the bent pipe shape is not easily assembled in the housing originally, when the extension angle of the second space is changed, for example, when the included angle of the second space extending from the first space is smaller, that is, the bending angle of the outlet pipe must be larger, the outlet pipe is relatively not easily installed in the housing, and therefore, only the housing suitable for the first space with a specific extension angle or a larger extension angle can be installed, and the applicable housing shape is greatly limited.

Disclosure of Invention

The main objective of the present invention is to provide a faucet structure, which can greatly reduce the volume of the main body part of the faucet housing in the radial direction, and eliminate the large lead angle structure that must be formed at the joint of the main body part and the faucet part, so as to improve the appearance and aesthetic feeling of the faucet housing, and effectively reduce the mold opening and material cost of the faucet housing. In addition, even if other included angles are formed between the water nozzle part of the faucet shell and the body part, such as any included angle between 75 and 105 degrees, the above purpose can still be effectively achieved without any influence.

In order to achieve the above object, the present invention provides a faucet structure including:

the faucet structure of the invention can be arranged on the peripheral wall by the water outlet interface of the valve seat, and the embedding space is radially arranged on the valve seat, even the opening is communicated with the embedding space and the installation valve slot, so that the connecting piece assembled in the embedding space can be connected with the water outlet interface in a water flow communication way, and can be radially fused into the original wall thickness space of the valve seat to the maximum extent, the radial volume of the combined two is minimized, meanwhile, the design that the connecting piece is naturally limited between the valve seat and the relative inner peripheral wall of the body part after installation can reduce the arrangement of any fastening piece or limiting piece, is beneficial to simple and rapid assembly and positioning, and can ensure that the radial volume of the body part is minimized, thereby greatly reducing the body diameter of the body part of the faucet shell and obtaining a slimmer appearance, and effectively reduces the die sinking and material cost.

The invention utilizes the design that the connecting piece is arranged on the side around the valve seat, and can also lead the connecting piece to be capable of directly and longitudinally extending to the junction of the body part and the water nozzle part without any bending structure design, and simultaneously, the diversion outlet assembled and connected by the water inlet end of the water outlet pipe on the connecting piece is skillfully designed and positioned at the junction, so that the water outlet pipe can be directly assembled and connected to the diversion outlet only by extending along the extending direction of the water nozzle part or even extending in a straight line without any bending structure design, thus the two can carry out the assembly and connection of a specific angle by utilizing the narrow space existing at the junction of the body part and the water nozzle part with the minimum space requirement, and further ensure that the junction of the body part and the water nozzle part does not need to be additionally designed with any redundant and space-occupying diversion angle structure, thereby improving the appearance modeling texture and aesthetic feeling of the tap shell, can also effectively reduce the mould opening and material cost.

The invention utilizes the design that the connecting piece is arranged on the peripheral side of the valve seat, and the flow guide inlet and the flow guide outlet of the connecting piece do not occupy any space of the mounting chamber, and the rest parts can be in a flat and thin design in the radial direction, so the space occupied in the radial direction can be effectively reduced under the same or even larger water cross section area, in other words, the mounting chamber can meet the mounting requirement of the connecting piece in the radial direction only by providing smaller radial space, and the body diameter of the body part can be further reduced.

The invention utilizes the horizontal part of the connecting piece to be designed into a joint shape, so that the connecting piece can be directly and hermetically inserted into the water outlet joint of the valve seat, and the connecting piece is provided with a clamping block which can be elastically clamped and positioned in each opposite clamping groove of the valve seat, therefore, the connecting piece can be accurately and quickly installed and positioned on the valve seat and cannot be moved along the longitudinal direction, and the connecting piece can be subsequently limited between the valve seat and the installation cavity of the body part to prevent the connecting piece from being radially separated from the valve seat, therefore, the connecting piece can be quickly and firmly installed on the valve seat and in the body part without using any fasteners such as bolts and special tools, and the connecting piece can achieve the effects of simple, quick and firm assembly.

The invention can be assembled and inserted on the first plastic forming part in a telescopic and adjustable way by utilizing the second plastic forming part of the connecting piece, so that the flow guide outlet of the connecting piece can be correspondingly adjusted in length along with the height position of the water nozzle part on the body part, and the connecting pieces with different lengths are not required to be designed to match with the faucet shell, thereby reducing the die sinking and material preparation cost of the connecting piece.

The water outlet pipes of the invention can be installed on various tap shells with the included angle between the water nozzle part and the body part between 75 and 105 degrees by utilizing the design of two different extending directions, and are not limited to the shape vertical to 90 degrees.

Fourthly, the horizontal portion 302 of the joint 30 can be designed into a joint shape so as to be directly inserted into the outlet 215 of the valve seat 21 in a sealing manner, and at the same time, the joint 30 can be elastically locked and positioned in the corresponding locking slots 213a of the valve seat 21 by the locking blocks 34 designed on the joint 30, so that the joint 30 can be accurately and quickly installed and positioned on the valve seat 21 and limited from moving in the longitudinal direction, and the joint 30 can be subsequently installed in the installation chamber 113 of the body part 11 along with the valve assembly 20 and naturally limited between the valve seat 21 and the inner peripheral wall 110 of the installation chamber 113 of the body part 11 so as to prevent the joint 30 from being radially separated from the valve seat 21, so that the joint 30 can be quickly and firmly installed on the valve seat 21 and in the body part 11 without using any fastening members such as bolts and special tools, and the assembling operation of the joint 30 is simple, and easy, Fast and firm.

Fifth, the links of the present invention have a variety of molding or assembly configurations to choose from.

Or respectively forming the plastic molding member 303 and the plug 304, and then assembling the plug 304 in the mold drawing hole 303c of the plastic molding member 303 to form the connection member 30a, wherein the plug 304 can be skillfully fixed by the original locking piece 63 for fixing the cold and hot

water inlet pipes

61 and 62 or another locking piece. It can be readily appreciated that the adapter 30b can also be molded using two shots of plastic. More specifically, a first plastic molding 307 and a second plastic molding 308 can be molded separately, and the second plastic molding 308 can be assembled and inserted into the first plastic molding 307 in a telescopic manner to form the connecting member 30 c. Accordingly, the present invention provides a variety of alternative connectors of different shaped or assembled configurations that can be used to achieve the desired results.

Sixth, as mentioned above, the joint member 30c according to the fourth embodiment of the present invention can be assembled and inserted onto the first plastic molding 307 by the second plastic molding 308 in a telescopic adjustable manner, so that the diversion outlet 32 of the joint member 30c can be adjusted in length along with the height position of the water nozzle portion 12 on the main body portion 11, and there is no need to design a plurality of joint members 30c with different lengths to match the faucet housing 10, thereby reducing the mold opening and material preparation cost of the joint member 30 c.

Seventh, the water outlet pipe 40 of the present invention can be applied not only to the faucet housing 10 with the water nozzle portion 12 extending vertically at 90 degrees to the main body portion 11, but also to the faucet housing 10 with the water nozzle portion 12 forming an angle with the main body portion 11 ranging from 75 to 105 degrees. For example, by adopting the technical means disclosed in the fourth embodiment, that is, a small portion of the water outlet pipe 40 close to the water inlet end 41 and the rest of the water outlet pipe are respectively formed with two different extending directions x4, x3, the water outlet pipe 40 can conform to the extending direction of the water nozzle portion 12 by the extending direction x3 of the rest of the water outlet pipe 40, and the extending direction x4 of the small portion close to the water inlet end 41 ensures that the water inlet end 41 can be simultaneously provided with the connecting piece 30c suitable for sharing, so that various matching connecting pieces are not required, and the mold opening and material preparation costs of the connecting piece 30c can be reduced.
