Description

Technical Field

[0001] The utility model relates to the technical field of faucet structures, and in particular to a pull-out faucet with a large flow rate. Background Art

[0002] In order to increase the flow rate of the current pull-out faucet, it is generally necessary to redesign the internal structure of the valve core to meet the greater water output demand, and at the same time, a water pump is used to provide a greater water output pressure to increase the water output flow rate. In particular, the emergence of a new valve core has further increased the water flow rate of the valve core. However, due to the limitation of the inner diameter of the valve core seat pipe, the valve core cannot fully reach the maximum water output flow rate, which wastes the performance of the valve core and cannot fully utilize the limited valve core seat space; the inlet and outlet interfaces of the valve core seat generally adopt a "pin"-shaped design, such as a combined kitchen basin pull-out faucet noise reduction valve core disclosed in CN110762252A, but this design will limit the inner diameter of the pipe, because after increasing the pipe size, the outer side of the interface is easy to hinder the pull-out of the pull-out pipe, affecting the pull-out effect, and the pull-out space is small. Utility Model Content

[0003] The utility model discloses a large-flow pull-out faucet, aiming to improve the problem of how to avoid the pull-out pipe from being stuck after the inner diameter of the pipe of the existing pull-out faucet is increased to improve the flow.

[0006] Furthermore, the central axis directions of the first threaded interface, the second threaded interface and the third threaded interface are parallel to the connection surface between the valve core seat and the valve core.

[0007] Furthermore, there is a height difference between the openings of the second threaded interface, the first threaded interface, and the third threaded interface, and the first threaded interface is higher than the third threaded interface and lower than the second threaded interface.

[0008] Furthermore, an inclined surface is provided at the upper end of the first threaded interface and the third threaded interface on a side close to the drawer space to facilitate the drawer tube to enter the drawer space.

[0009] Furthermore, the inner diameters of the first threaded interface, the second threaded interface and the third threaded interface are 9 mm to 9.5 mm.

[0010] Furthermore, the inner diameter of the pulling tube is 7.5 mm to 7.7 mm.

[0011] Furthermore, the inner diameter of the water outlet pipe is 5.5 mm.

[0012] Furthermore, the inner diameter of the water inlet pipe is 7.8 mm.

[0013] Beneficial effects:

[0014] In this embodiment, the diameters of the water inlet pipe, the water outlet pipe and the pull-out pipe are increased to increase the water flow rate within the limited body space. The structure of the valve core seat is optimized to form an "L"-shaped threaded interface layout to provide a larger and wider pull-out space for the pull-out pipe within the limited body space, thereby preventing the pull-out pipe from being stuck during pulling due to the increase in the pipe diameter, thereby affecting the pulling effect.

DETAILED DESCRIPTION

[0021] Combination Figures 1 to 5As shown in the figure, this embodiment provides a large-flow pull-out faucet, which includes a pull-out pipe 2, a first water inlet pipe 3, a second water inlet pipe 4, a water outlet pipe 5, a valve core seat 6, and a valve core 7 installed on the valve core seat 6. The valve core seat 6 includes a first threaded interface 61, a second threaded interface 62, and a third threaded interface 63. Among them, the first threaded interface 61 is arranged on the back surface of the valve core seat 6 for connecting the first water inlet pipe 3, and the second threaded interface 62 is arranged in parallel on the side of the first threaded interface 61 for connecting the water outlet pipe 5; the third threaded interface 63 is arranged above the second threaded interface 62 for connecting the second water inlet pipe 4. The first threaded interface 61, the second threaded interface 62, and the third threaded interface 63 form an "L"-shaped structural layout to form a pull-out space 64 suitable for the movement of the large-diameter pull-out pipe 2 on the side of the third threaded interface 63 close to the first threaded interface 61.

[0022] In this embodiment, the valve core 7 is installed on the valve core seat 6. Both the valve core 7 and the valve core seat 6 are arranged inside the faucet body 1, and a side handle is arranged on the side of the body 1. Here, the installation direction of the valve core 7 on the valve core seat 6 is perpendicular to the installation directions of the pull-out pipe 2, the first water inlet pipe 3, and the second water inlet pipe 4.

[0023] In the prior art, the diameter of the pull-out pipe 2 is generally less than 6.6 mm, the inner diameter of the water outlet pipe 5 is generally less than 5.12 mm, the inner diameter of the water inlet pipe is generally less than 7.5 mm, and the inner diameter of the threaded interface of the valve core seat 6 is generally less than 7 mm. This is because the existing valve core seat 6 adopts a "pin"-shaped interface layout, and the pull-out pipe 2 passes through the gap between the two water inlet pipes. Therefore, if the diameter is too large, it cannot pass through the gap between the two interfaces, and if the interface inner diameter of the valve core seat 6 is too large, the gap will be smaller, thus affecting the pulling of the pull-out pipe 2. This results in a waste of a large amount of space inside the limited body 1. Therefore, through the re-design of the structural layout of the valve core seat 6 in this application, a larger pull-out space 64 can be provided within the limited space, and the inner diameters of the water inlet pipe, the water outlet pipe 5, and the pull-out pipe 2 can be increased, thereby realizing an increase in the flow rate.

[0024] Combined with Figures 3 to 5As shown, specifically, the first threaded interface 61 and the second threaded interface 62 are arranged in parallel and arranged on the back of the valve core seat 6, and the third threaded interface 63 is arranged above the second threaded interface 62, so that the first threaded interface 61, the second threaded interface 62 and the third threaded interface 63 form an "L"-shaped structural layout. Under this arrangement, a relatively large pull-out space 64 can be formed on the side of the first threaded interface 61 and the third threaded interface 63, and the increase in the inner diameter of the interface has little effect on the pull-out space 64. Here, the central axis directions of the first threaded interface 61, the second threaded interface 62 and the third threaded interface 63 are parallel to the connection surface between the valve core seat 6 and the valve core 7, and the inner diameters of the three threaded interfaces can be set to be the same. Preferably, there is a height difference at the openings of the second threaded interface 62, the first threaded interface 61 and the third threaded interface 63, and the first threaded interface 61 is higher than the third threaded interface 63 and lower than the second threaded interface 62. This arrangement can ensure that the metal rings between the water inlet pipe and the water outlet pipe 5 will not rub against each other during installation or disassembly, and the stress positions can be staggered, thereby increasing the service life of the valve core seat 6 after the pipeline is installed.

[0025] In a preferred embodiment, the upper ends of the first threaded interface 61 and the third threaded interface 63 near the drawing space 64 are provided with an inclined surface 65 to facilitate the drawing tube 2 to enter the drawing space 64, and to prevent the pipe from being stuck on the upper side of the valve core seat 6 during the drawing process. Furthermore, the inner diameters of the first threaded interface 61, the second threaded interface 62 and the third threaded interface 63 are 9 mm to 9.5 mm, preferably 9.2 mm.

[0026] In one embodiment, the inner diameter of the pull-out tube 2 is 7.5 mm to 7.7 mm, preferably 7.6 mm; the inner diameter of the water outlet pipe 5 is 5.5 mm, and the inner diameters of the first water inlet pipe 3 and the second water inlet pipe 4 are 7.8 mm. Under this inner diameter design, when the water pressure is 3 bar, the water flow rate can reach 9.5 L / min. Compared with the existing flow rate of 7.8 L / min, the water flow rate is increased by 21% in the same size of the body 1 space, which can meet greater water demand and improve the experience.

[0027] It should be understood that the above are only preferred implementations of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model.

[0028] The above description of the drawings used in the implementation manner only shows certain embodiments of the utility model and should not be regarded as limiting the scope. For ordinary technicians in this field, other relevant drawings can be obtained based on these drawings without paying creative work.
