Description

Technical Field

[0001] The present invention relates to the technical field of sanitary ware, and more particularly, to a kitchen faucet structure and an installation method thereof. Background Art

[0002] With the continuous improvement of living standards, the demand for kitchen faucets has also increased. Due to the short distance between the outlet pipe of the traditional faucet and the sink, when people need to fill a large-capacity container with water, it will cause a great hindrance to water use and cause a lot of inconvenience.

[0003] Therefore, an elastic member is sleeved on the outlet pipe. When the outlet pipe is bent, that is, when the water outlet end is to be placed in the sink, the elastic member sleeved on the outlet pipe will also be bent accordingly. Since the elastic member is elastic, the elastic member will provide an elastic force to the outlet pipe, so that the water outlet end can float well in the air without being fixed by a bracket, thus avoiding the unrestricted situation of the water outlet end in the sink. And when the water outlet end is clamped on the bracket, the water outlet end abuts against one end of the fixed sleeve. At this time, since the outlet pipe is also bent, the elastic member provides a force to the water outlet end to always abut against the fixed sleeve, thus preventing the water outlet end from accidentally falling off.

[0004] However, for the kitchen faucets on the market currently, the water nozzle of the water outlet end is directly connected to the outlet pipe, resulting in inflexible water use operation, inconvenient sleeving of the elastic member outside the pipe, lack of connection limit, affecting the function realization of the elastic member, and prone to failure risks.

Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Example

[0035] Combination Figures 1 to 4 The present embodiment provides a kitchen faucet structure, including a body component and a water inlet and outlet component. The body component includes a seat body 1 with an external handle 3 and a bracket 2 configured on the seat body 1. The water inlet and outlet component has an inlet pipe 4, an outlet pipe 5, a valve core 6 and a valve seat 7. The valve core 6 is arranged in linkage with the handle 3, and the valve seat 7 is used to install the valve core 6 in the seat body 1, and the inlet pipe 4 and the outlet pipe 5 are respectively connected to the valve core 6 to cooperate with the water outlet.

[0036] A connecting member 8 is provided on the top of the seat body 1, and the bracket 2 is limited on the seat body 1 in a horizontal transverse state through the connecting member 8. One end of the water outlet pipe 5 is docked on the connecting member 8, and the other end is connected to an extraction head 10 through a movable joint 9, and the extraction head 10 is detachably connected and configured on the bracket 2. The water outlet pipe 5 is sleeved with a spring member 11, one end of the spring member 11 is screwed to the connecting member 8, and the other end is screwed to the movable joint 9. The extraction head 10 is provided with a step portion 12, and the step portion 12 is provided with a clamping ring 13 for limiting the rotation of the spring member 11. The clamping ring 13 and the movable joint 9 are correspondingly arranged on the step portion 12 and hidden in the extraction head 10 and the water outlet pipe 5, so that the extraction head 10 and the water outlet pipe 5 are an integrated structure in appearance.

[0037] The kitchen faucet structure mentioned above is limited on the base body 1 by a connecting piece 8 on the bracket 2, and a movable joint 9 is provided between the extraction head 10 of the water outlet end and the water outlet pipe 5. One end of the spring member 11 sleeved outside the water outlet pipe 5 is screwed on the connecting piece 8, and the other end is screwed on the movable joint 9, so that the two ends of the spring member 11 can be stably limited and constrained in the water outlet pipe 5, so that whether it is used for pulling or the bracket 2, the spring member 11 with both ends constrained can provide a more efficient and stable elastic force to the water outlet.

[0038] In this embodiment, a movable joint 9 is provided at the water outlet end by docking between the extraction head 10 and the water outlet of the water outlet pipe 5, thereby improving the flexibility of the extraction head 10 when using the water outlet. In particular, the step portion 12 provided on the extraction head 10 can hide the clamping ring for limiting the rotation of the spring member 11 and the movable joint 9 therein, so that after the extraction head 10 is installed on the water outlet pipe 5, the two can be seamlessly connected together, forming an integrated structural shape, which can improve the overall appearance and make the sealing of the mutual connection better.

[0039] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the connector 8 is configured as a water outlet rod, which is connected to the water outlet end of the valve core 6 and the water inlet of the water outlet pipe 5. The water outlet rod serves the purpose of connecting the water outlet on one hand, and serves as a connecting structure of the bracket 2 on the seat body 1 on the other hand. It should be mentioned that the water inlet pipe 4 is equipped with at least cold and hot water pipes, which are respectively connected to the water inlet end of the valve core 6. The existing water connection between the water inlet pipe 4, the valve core 6, the water outlet rod and the water outlet pipe 5 is not limited here.

[0040] In this embodiment, the bracket 2 forms a plug-in portion 14 with a mounting hole 15 at one end thereof, the plug-in portion 14 is fitted and matched with the seat body 1, and the water outlet rod is docked in the mounting hole 15 to connect the internal valve core 6 and the external water outlet pipe 5. The plug-in portion 14 is sleeved in the upper opening of the seat body 1 through a plurality of bushings 16. It should be noted that the bracket 2 forms a lateral arc groove suitable for placing the extraction head 10 at the other end thereof, and the bracket 2 and the extraction head 10 are magnetically matched.

[0041] Furthermore, a one-way valve 17 is provided inside the water outlet rod, and the water outlet rod is formed with an external thread suitable for the spring member 11, and a limiter 18 for the spring member 11 is sleeved on the external thread. Among them, the limiter 18 is preferably a clamping ring structure. Therefore, both ends of the spring member 11 are connected to the connecting member 8 and the movable joint 9 by means of threaded matching and clamping ring limiting, which plays a more stable connection and adaptation. The threaded connection at both ends better fixes the spring member 11, prevents the spring member 11 from detaching from the bracket 2 during use, and can be fixed together with the water outlet pipe 5 and the movable joint 9 by means of limiters such as clamping rings.

[0042] It should be understood that the movable joint 9 is constructed of a polymer material with self-lubricating properties, so that when used as a friction pair, no external lubricant is required, and low friction and low wear performance can be exhibited during relative friction. The movable joint 9 uses a self-lubricating material, so that the movable joint 9 and the extraction head 10 can rotate without driving the spring member 11 to rotate. In addition, the selection of polymer materials in the joint is an application of existing materials and will not be elaborated here.

[0043] As Figure 2 shown, in this embodiment, the stepped portion 12 is recessed and provided on the top of the extraction head 10, and the water outlet of the water outlet pipe 5 is tightly connected to the extraction head 10 through the movable joint 9. Among them, the stepped portion 12 is recessed in the top end face of the extraction head 10 and has at least a plurality of stepped structures for adapting to the installation and cooperation of the movable joint 9, and the movable joint 9 has an external thread, and the snap ring is sleeved between one of the stepped structures and the external thread. Thus, the connection of the movable joint 9 in the stepped portion 12 makes the sealing performance of the water outlet end better, and the connection structure between the extraction head 10 and the water outlet pipe 5 is hidden, making the water outlet end of the entire faucet more beautiful and flat.

[0044] As Figure 2 shown, in this embodiment, the seat body 1 is provided with a communication hole 19 on its side, a sleeve 20 is installed on the communication hole 19, the valve core 6 is arranged in the sleeve 20, and the handle 3 is arranged on one side of the sleeve 20. Among them, the sleeve 20 is screwed and adapted to the valve seat 7, and the valve seat 7 is arranged in the seat body 1 in an expanded form through the pin 22, and the valve seat 7 and the seat body 1 are locked by a nut 21, so that the sleeve 20 is tightly clamped with the upper end side of the communication hole 19, thereby leaving a gap on the lower end side of the communication hole 19.

[0045] In the above, due to the threaded connection between the sleeve 20 and the valve seat 7, there must be an assembly gap reserved between the sleeve 20 and the communication hole 19 on the seat body 1 to facilitate the quick installation of the sleeve 20. In this regard, by locking the valve seat 7 with the nut 21, the sleeve 20 can be tightly connected to the upper end of the seat body 1, so that the assembly gap is accumulated at the lower end of the seat body 1. From the user's perspective, its appearance is more beautiful and the gap defect is invisible.

[0046] Combined with Figures 5 to 8 , this embodiment further provides an installation method for the structure of a kitchen faucet. Based on the above-mentioned structure of the kitchen faucet, it includes the following steps:

[0047] S1: Install the valve seat 7 with the pin 22 and expand and pre-tighten it on the seat body 1, and the sleeve 20 is externally connected to the seat body 1 and threadedly fixed to the valve seat 7 to form a whole;

[0048] S2: Install the valve core 6 and the handle 3 corresponding to the sleeve 20, and lock the valve seat 7 and the sleeve 20 on the seat body 1 with the nut 21;

[0049] S3: Provide the connecting piece 8 to install and fix the bracket 2 on the seat body 1, and dock the water outlet pipe 5 on the connecting piece 8. A spring member 11 is sleeved on the water outlet pipe 5, and the spring member 11 is screwed between the connecting piece 8 and the extraction head 10 of the water outlet pipe 5;

[0050] S4: Fix the spring member 11 with the movable joint 9 and fix the end of the spring member 11 within the step portion 12 of the outlet pipe 5 through a snap ring.

[0051] S5: Connect the extraction head 10 to the movable joint 9 and enable the extraction head 10 to be supported and configured on the bracket 2.

[0052] In the above installation method, the valve seat 7 is expanded and pre-tightened in the seat body 1. After the sleeve 20 is docked to the valve seat 7, the two are locked to the seat body 1 through the nut 21 to achieve the purpose of stable installation. The bracket 2 is installed and fixed on the seat body 1 through the connecting member 8, and both ends of the spring member 11 sleeved on the outlet pipe 5 are respectively screwed to the connecting member 8 and the movable joint 9 to achieve the effect of overall spring limit constraint. Finally, the extraction head 10 is flexibly connected to the movable joint 9 to realize the free switching of the use state of the extraction head 10 on the bracket 2.

[0053] Among them, it should be understood that the cold and hot water of the inlet pipe 4 are docked to the valve seat 7 or the valve core 6, which can be carried out synchronously when the valve seat 7 is installed in the seat body 1. Thus, the cold and hot water enters the internal mixing cavity through the water inlet end of the valve core 6, and then the mixed water is output from the water outlet end of the valve core 6 to the outlet pipe 5 for supplying the water outlet of the pull-out head.

[0054] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention.
