Description

Technical Field

[0001] This utility model belongs to the field of faucet technology, specifically a 7-shaped swing arm faucet. Background Technology

[0002] A faucet is a common name for a water valve, used to control the flow of water and thus saving water. Faucets are constantly being updated, evolving from old-fashioned cast iron faucets to electroplated knob faucets, and then to stainless steel single-temperature single-control faucets, stainless steel dual-temperature dual-control faucets, and semi-automatic kitchen faucets. Now, more and more faucets of different materials, functions, and styles are appearing in our daily lives.

[0003] The 7-shaped swing arm faucet is a common type of faucet. It consists of a vertically mounted column, the lower end of which is fixed to the countertop. The upper end of the column has a swing arm that adjusts the height of the faucet. The position of the faucet spout is adjusted by rotating the column and the swing arm. However, existing rotating structures for the column and swing arm are mostly achieved through a pivot, and the swing arm's swing amplitude is controlled by a retaining ring or positioning screw. This method is complex, inconvenient to install, and extremely costly. In addition, existing faucet installation and fixing methods involve installing a threaded tube at the bottom of the faucet, passing it through the countertop surface, and then screwing a nut into the threaded tube from the bottom of the countertop to tighten and fix the faucet. The disadvantages are that the space under the countertop is narrow, the operation of screwing in the nut is difficult and it is hard to apply force, making it difficult to install and lock. Moreover, existing faucets have limited functionality and are not practical enough. Utility Model Content

[0049] In one possible implementation, the top of the swing arm 2 is provided with a digital display panel 22, which displays the water type and its TDS value in real time, as well as the filter cartridge life status.

[0050] In one possible implementation, the open end of the barb 31 faces outward, and its opening is engaged with the inner side of the first limiting rib 11, and the barb 31 is slidably connected to the first limiting rib 11.

[0051] In one possible implementation, a barb 31 is provided.

[0052] In one possible implementation, three barbs 31 are provided.

[0053] In one possible implementation, four barbs 31 are provided.

[0054] In one possible implementation, five barbs 31 are provided.

[0055] In one possible implementation, six barbs 31 are provided.

[0056] It is worth noting that in this application, the barb 31 can be selected according to actual needs.

[0057] In one possible implementation, the open end of the barb 31 faces outward, and its opening is engaged with the inner side of the first limiting rib 11, with the barb 31 and the first limiting rib 11 being slidably connected.

[0058] In one possible implementation, a limiting block 12 is provided on the inner side of the first limiting rib 11 to limit the rotation angle of the swing arm 2.

[0059] In one possible implementation, there are two limiting blocks 12, and the angle between the two limiting blocks 12 and the center of the column 1 is 60°, at which time the swing arm 2 rotates at an angle of 120°.

[0060] In one possible implementation, the two limiting blocks 12 form a 90° angle with the center of the column 1, at which point the swing arm 2 rotates at a 90° angle.

[0061] In one possible implementation, the two limiting blocks 12 form an angle of 120° with the center of the column 1, at which point the swing arm 2 rotates at an angle of 60°.

[0062] It is worth noting that in this application, based on the angle between the two limiting blocks 12 and the center of the column 1, the rotation angle of the swing arm 2 can be 0-180°.

[0063] In addition, the number and position of the limit blocks 12 in this application can be selected according to actual needs.

[0064] In one possible implementation, the column 1 adopts a cylindrical structure, and the column 1, the first limiting rib 11, and the limiting block 12 adopt an integral cast-in-place structure.

[0065] The connector 3 is located at the bottom of the end of the swing arm 2 away from the outlet. The swing arm 2, connector 3, and barb 31 are integrally cast.

[0066] By adopting the above technical solution:

[0067] Two barbs 31 are provided below the connector to engage with the first limiting rib 11, so as to realize the rotational connection between the swing arm 2 and the column 1, prevent the swing arm 2 from being pulled out, and limit the rotation angle of the swing arm 2 by setting the limiting block 12. The structure is simple, easy to install, low in cost, and highly practical.

[0068] In one possible implementation, the threaded nut 6 is inserted into the outer side of the lower end of the column 1, and the outer side of the threaded nut 6 is provided with a fixing protrusion 63. The outer side of the column 1 is provided with a corresponding fixing hole 13, and the fixing protrusion 63 is correspondingly engaged in the fixing hole 13 for fixing the column 1.

[0069] The outer side of the threaded nut 6 has a pressing groove 61, and the outer end of one side wall of the pressing groove 61 has a pressing spring piece 62. The fixing protrusion 63 is located on the outer side of the free end of the pressing spring piece 62.

[0070] The threaded tube nut 6 has a fastening screw hole 64 on the outside for fastening and fixing the threaded tube 5 and the threaded tube nut 6.

[0071] In one possible implementation, rubber gaskets are provided on both the upper and lower sides of the connection between the dental tube 5 and the edge of the water platform.

[0072] The outer side of the threaded nut 6 is provided with several No. 2 limiting ribs 65 in the vertical direction, and the inner side of the lower end of the column 1 is provided with several limiting grooves for guiding the installation and limiting of the column 1.

[0073] In one possible implementation, a nut wrench 7 is also included for disassembling the column 1 and the threaded tube nut 6;

[0074] The nut wrench 7 has a nut slot 71 at one end, and the nut slot 71 has a nut limiting groove 72 corresponding to a number of second limiting ribs 65, which is used for disassembling the threaded tube nut 6.

[0075] The end of the nut wrench 7 away from the nut slot 71 is provided with a push rod 73, which is used to press the fixing protrusion 63 to realize the disassembly of the column 1.

[0076] In one possible implementation, the dental tube 5 first extends from the bottom of the water platform to the top of the water platform, and a rubber washer with double-sided adhesive is installed on the bottom end face of the dental tube 1, so that the dental tube 1 and the washer can be attached together to the bottom of the water platform and will not fall off.

[0077] In one possible implementation, the upper part of the toothed tube 5 has two round holes for holding the toothed tube 5 to prevent it from falling and to prevent the toothed tube 5 from rotating when tightening the toothed tube nut 6, so as to facilitate tightening.

[0078] In one possible implementation, the threaded nut 6 is inserted into the threaded tube 5 from the top of the water platform and tightened to secure it. This allows for unobstructed operation, enabling the operator to stand comfortably without having to squat or crawl into the narrow space at the bottom of the water basin, making the operation more user-friendly.

[0079] In one possible implementation, the threaded nut 6 includes an elastic cylindrical protrusion structure that engages with the faucet post circular hole (fixed hole 13) to lock in place and restrict the faucet from being pulled out; the elastic cylindrical protrusion (fixed protrusion 63) has a connecting boss in the upper and lower gaps. Before use, the boss connection point is cut open (keeping the boss), so that the cylindrical protrusion can be elastically reciprocated and locked in place while there is no gap between the upper and lower parts and it will not loosen.

[0080] In one possible implementation, the threaded nut 6 includes a set screw hole, and after the threaded nut 6 is tightened, a locking screw and the threaded tube 5 can be added to fix it in place to prevent rotation and loosening.

[0081] In one possible implementation, the faucet can be installed by inserting the threaded nut 6 (so that the elastic cylindrical protrusion of the threaded nut 6 is engaged with the round hole of the faucet post, preventing the faucet from being pulled out), without the need for locking screws; ribs are made on both the faucet post and the threaded nut 6 to cooperate with each other to prevent the faucet post from rotating; the faucet post and the threaded nut 6 are slightly interference-fitted to prevent the faucet from loosening.

[0082] In one possible implementation, the nut wrench 7 has a protruding push rod 73 that is inserted into the fixing hole 13 to push out the elastic cylindrical protrusion (fixing protrusion 63), allowing the faucet to be removed for replacement or maintenance.

[0083] Furthermore, such as Figure 3 As shown, the current method of installing and fixing faucets involves installing a threaded tube at the bottom of the faucet, passing through the surface of the sink, and then screwing a nut into the threaded tube from the bottom of the sink to tighten and fix the faucet. The disadvantage is that the space under the sink is narrow, the operation of screwing in the nut is difficult and it is hard to apply force, making it difficult to install and lock. In this application, the threaded tube 5 passes through the bottom of the sink and is fixed by the threaded tube nut 6. The column 1 and the threaded tube nut 6 are connected by a snap-fit. Most of the entire installation process is completed above the sink, with free and unobstructed operating space. The operator can stand and stretch out without having to squat down and crawl into the narrow space under the sink to operate, making it more user-friendly.

[0084] In one possible implementation, a ceramic valve core is used; this allows for both single-inlet and dual-inlet faucet functions.

[0085] In one possible implementation, a digital display panel can be installed to create a smart digital display faucet—showing the water type (pure water) and its TDS value, as well as the filter life status in real time; alternatively, a regular faucet can be used without the digital display panel.

[0086] In one possible implementation, the swing arm 2 and the column 1 are fitted together by a sealing ring to eliminate the gap between the swing arm 2 and the column 1 and the damping during rotation. The damping can be adjusted as needed by adjusting the sealing ring.

[0087] In one possible implementation, a top knob controls the faucet switch. The knob contains a magnet, and a reed switch or Hall effect switch is installed at the bottom of the corresponding position. When the knob is turned to the corresponding position, the reed switch or Hall effect switch senses the magnet and is turned on to provide a control signal to the digital display board.

[0088] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
