Description

Technical Field

[0001] This application relates to the field of faucet technology, and in particular to a base and faucet with an air gap function. Background Technology

[0002] Water purifiers are common household appliances, and the faucets used with them are designed to meet the purifier's requirement to output purified water. Faucets are typically installed above a countertop in the user's home. To secure the faucet, holes need to be drilled in the countertop. A retaining block is then installed below the countertop, and a mounting base is installed above. The mounting base is then bolted to the retaining block, allowing the faucet to be installed on the retaining block.

[0003] Water purifiers typically have a purified water outlet and a wastewater outlet. The purified water outlet is connected to a faucet via a water pipe, allowing the purified water to be discharged from the faucet. The wastewater outlet is usually connected directly to the sewer pipe via a wastewater pipe. Chinese Patent Publication No. CN207539371U discloses a water purifier faucet that integrates an air gap assembly. This air gap assembly is connected to the wastewater outlet of the water purifier, allowing for uninterrupted wastewater drainage.

[0004] However, since the air gap component is integrated into the faucet, it cannot meet the user's need to observe the wastewater discharge when the water purifier is equipped with a conventional faucet. Therefore, how to design a technology that allows users to observe the wastewater discharge of the water purifier and improves its versatility is the technical problem this utility model aims to solve. Utility Model Content

[0005] The technical problem to be solved by this application is to provide a base and faucet with an air gap function, so as to realize the function of integrating an air gap into the base, to meet the requirements of observing the wastewater discharge of different water purifiers, to meet the installation and use requirements of more types of faucets, and thus improve the versatility of use.

The air gap body is provided with a drain hole and a water flow channel. The inlet wastewater pipe is connected to the drain hole through the water flow channel. The drain hole is arranged above the outlet wastewater pipe, and an air gap interval area is formed between the drain hole and the inlet of the outlet wastewater pipe. The air gap assembly is mounted on the upper mounting base, and the wastewater inlet pipe and the wastewater outlet pipe are arranged outside the through-hole.

[0007] Furthermore, the air gap body includes a base and a cover. The base is provided with a water connection hole, a water connection groove and a drain hole. The water connection hole and the drain hole are connected through the water connection groove. The cover is sealed on the base and covers the connecting water hole, the connecting water groove and the drain hole, and the water flow channel is formed between the connecting water groove and the cover; The wastewater inlet pipe is connected to the connecting water hole.

[0008] Furthermore, the base is provided with a boss, the upper surface of the boss is an arc-shaped surface, the connecting water groove is provided on the arc-shaped surface, and the boss is located between the connecting water hole and the drain hole; The cover is provided with a mounting slot, and the boss is inserted into the mounting slot.

[0009] Furthermore, the base body and the upper mounting base are an integral structure, or the base body is fixedly mounted on the upper mounting base; And / or, the base and the wastewater inlet pipe are an integral structure, or the wastewater inlet pipe is fixedly installed on the base; And / or, the wastewater discharge pipe and the upper mounting base are an integral structure, or the wastewater discharge pipe is fixedly installed on the upper mounting base.

[0010] Furthermore, it also includes a decorative cover; the top surface of the decorative cover is provided with an insertion port, the side wall of the decorative cover is provided with an observation port, the decorative cover is disposed on the upper mounting base and covers the upper mounting base, the insertion port is arranged above the through opening; the observation port is arranged outside the air gap interval area.

[0011] Furthermore, the upper mounting base and the lower locking base are connected together by locking bolts.

[0012] Furthermore, the upper mounting base is provided with a locking hole, and a protruding anti-retraction part is provided in the locking hole; The base with air gap function also includes a connector, the lower end of which is connected to the lower locking seat. The connector is inserted into the locking hole and abuts against the anti-reverse part. The anti-reverse part is configured to restrict the connector from sliding downward in the locking hole.

[0013] Furthermore, the anti-retraction part is an elastic claw, the lower end of the elastic claw is disposed on the hole wall of the locking hole, the elastic claw extends obliquely from bottom to top, and an anti-retraction space is formed between the upper end of the elastic claw and the hole wall of the locking hole; The connector passes through the stop space.

[0014] Furthermore, the anti-reverse part is an anti-reverse protrusion, which protrudes from the wall of the locking hole, and an anti-reverse space is formed between the anti-reverse protrusion and the wall of the locking hole; The connector passes through the stop space.

The upper mounting base and the lower locking base are connected together to clamp the mounting table together. An air gap component is integrated on the upper mounting base, and the wastewater inlet pipe of the air gap component can be connected to the wastewater outlet of the water purifier to allow users to observe the wastewater discharge through the air gap component. The air gap component is integrated on the upper mounting base, rather than on the faucet. Therefore, regardless of the type of faucet used, as long as it can be installed through the through-hole of the base, the air gap function of the base can be used to observe the wastewater. This breaks the dependence on dedicated faucets with integrated air gaps, realizes the function of the base integrating air gaps, meets the requirements of different water purifiers to observe the wastewater discharge, meets the installation and use requirements of more types of faucets, and thus improves the versatility of use.

[0017] Furthermore, by providing a stop in the locking hole of the upper mounting base, the stop can prevent the connector from sliding downwards in the locking hole. In actual operation, when the operator pulls the connector, it moves upwards through the locking hole until the lower locking seat is against the lower surface of the countertop. Because the connector is restricted by the stop in the locking hole and will not move downwards in the opposite direction without external force, the locking seat under the countertop can be tightened by pulling the connector, making it fit tightly against the lower surface of the countertop. Then, the faucet body can be installed and fixed on the base with air gap function to complete the faucet installation. Since it is not necessary to constantly pull the connector by hand, the operation is more convenient and the installation efficiency of the faucet is improved. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] like Figures 1-7 As shown, this application provides a base with an air gap function, comprising: Upper mounting base 1, wherein a through opening 11 is provided on the upper mounting base 1; The lower locking seat 2 is disposed below the upper mounting seat 1. The upper mounting seat 1 and the lower locking seat 2 are connected together, and a clamping space is formed between the upper mounting seat 1 and the lower locking seat 2. Air gap assembly 3 includes an air gap body 31, a wastewater inlet pipe 32, and a wastewater outlet pipe 33. The air gap body 31 is provided with a drain hole 311 and a water flow channel 312. The wastewater inlet pipe 32 is connected to the drain hole 311 through the water flow channel 312. The drain hole 311 is arranged above the wastewater outlet pipe 33. An air gap interval area is formed between the drain hole 311 and the inlet of the wastewater outlet pipe 33. The air gap assembly 3 is mounted on the upper mounting base 1, and the wastewater inlet pipe 32 and the wastewater outlet pipe 33 are arranged outside the through-hole 11.

[0023] Specifically, the upper mounting base 1 and the lower locking base 2 cooperate to achieve a fixed installation on the countertop in the user's home. The through-hole 11 on the upper mounting base 1 is used to meet the installation requirements of the faucet. At the same time, the upper mounting base 1 is also equipped with an air gap assembly 3. The inlet pipe 32 of the air gap assembly 3 is connected to the wastewater outlet of the user's water purifier, and the outlet pipe 33 of the air gap assembly 3 is connected to the user's sewer system through a pipe.

[0024] During use, the faucet is installed on the upper mounting base 1 and connected to the purified water outlet of the water purifier to supply water to the user. The wastewater generated by the water purifier enters the water flow channel 312 of the air gap body 31 through the wastewater inlet pipe 32, and the wastewater is sprayed downward from the drain hole 311 of the air gap body 31 into the wastewater outlet pipe 33, so that the user can easily observe the wastewater discharge.

[0025] Furthermore, by placing the air gap component 3 on the upper mounting base 1, the upper mounting base 1 can further meet the installation requirements of the faucet, thus allowing the air gap component 3 to be independent of the specific structure of the faucet. In addition, placing the air gap component 3 on the upper mounting base 1 facilitates the arrangement of the inlet and outlet water pipes 32 and 33, freeing them from the limitations imposed by the faucet's own structure on their installation arrangement. Moreover, compared to integrating the air gap component 3 separately for each faucet, concentrating the air gap function on the upper mounting base 1 reduces the manufacturing cost of a single faucet product, making it easier to promote and apply.

[0026] In one embodiment, the air gap body 31 includes a base 313 and a cover 314. The base 313 is provided with a connecting water hole 315, a connecting water groove 318, and a drain hole 311. The connecting water hole 315 and the drain hole 311 are connected through the connecting water groove 318. The cover 314 is sealed on the base 313 and covers the connecting water hole 315, the connecting water groove 318, and the drain hole 311. The connecting water groove 318 and the cover 314 form the water flow channel 312. The wastewater inlet pipe 32 is connected to the connecting water hole 315.

[0027] Specifically, the air gap body 31 adopts a split design to facilitate the formation of a water flow channel 312 inside. After the seat 313 and the cover 314 are sealed together, the connecting water tank 318 is covered by the cover 314 to form a water flow channel 312, and the wastewater inlet pipe 32 is connected to the water flow channel 312 through the connecting water hole 315.

[0028] In order to meet the requirements of a sealed connection, a sealing ring can be provided between the seat 313 and the cover 314. The sealing ring surrounds the outside of the connecting water hole 315, the connecting water tank 318 and the drain hole 311, and the sealing ring can seal the connection area between the seat 313 and the cover 314.

[0029] Furthermore, the base 313 is provided with a boss 316, the upper surface of the boss 316 is an arc-shaped surface, the connecting water groove 318 is provided on the arc-shaped surface, and the boss 316 is located between the connecting water hole 315 and the drain hole 311; the cover 314 is provided with an installation slot 317, and the boss 316 is inserted into the installation slot 317.

[0030] Specifically, the protrusion 316 on the base can be inserted into the mounting slot 317 formed on the cover 314, thus allowing the connecting water tank 318 to form a water flow channel 312 in the mounting slot 317. More importantly, since the connecting water tank 318 is formed on the arc-shaped surface of the protrusion 316, the water flow channel 312 forms an arc-shaped water flow path, thereby reducing water resistance to wastewater.

[0031] In one embodiment, there are multiple ways to connect the air gap body 31 to the upper mounting base 1.

[0032] For example, the seat 313 and the upper mounting base 1 are an integral structure, or the seat 313 is fixedly mounted on the upper mounting base 1. Specifically, the seat 313 and the upper mounting base 1 can be integrally injection molded or 3D printed. Alternatively, the seat 313 can be fixedly mounted on the upper mounting base 1 by means of adhesive, welding, or screw fixing.

[0033] For example, the base 313 and the wastewater inlet pipe 32 are an integral structure, or the wastewater inlet pipe 32 is fixedly mounted on the base 313. Specifically, the wastewater inlet pipe 32 can be integrally injection molded or 3D printed with the base 313. Alternatively, the water connection hole 315 is a threaded hole 23, and the wastewater inlet pipe 32 is threadedly connected to the water connection hole 315.

[0034] For example, the wastewater discharge pipe 33 and the upper mounting base 1 are an integral structure, or the wastewater discharge pipe 33 is fixedly mounted on the upper mounting base 1. Specifically, the wastewater discharge pipe 33 and the upper mounting base 1 can be integrally injection molded or 3D printed. Alternatively, the wastewater discharge pipe 33 can be fixedly mounted on the upper mounting base 1 by means of adhesive bonding, welding, etc.

[0035] Furthermore, it also includes a decorative cover 4; the top surface of the decorative cover 4 is provided with an insertion port 41, the side wall of the decorative cover 4 is provided with an observation port 42, the decorative cover 4 is disposed on the upper mounting base 1 and covers the upper mounting base 1, the insertion port 41 is arranged above the through port 11; the observation port is arranged outside the air gap interval area.

[0036] Specifically, the upper mounting base 1 is also equipped with a decorative cover 4 to optimize the overall appearance. The insertion port 41 on the decorative cover 4 cooperates with the through port 11 to meet the requirements for installing a faucet. The observation port 42 on the decorative cover 4 is located on the outside of the air gap interval area, allowing the user to observe the wastewater drainage situation in the air gap interval area through the observation port 42.

[0037] Compared with the prior art, the beneficial effects of this utility model are as follows: By configuring an upper mounting base 1 and a lower locking base 2, the upper mounting base 1 is placed on the mounting table, and the lower locking base 2 is placed at the bottom of the mounting table. The upper mounting base 1 and the lower locking base 2 are connected together to clamp the mounting table together. An air gap component 3 is integrated on the upper mounting base 1. The wastewater inlet pipe 32 of the air gap component 3 can be connected to the wastewater outlet of the water purifier to allow users to observe the wastewater discharge through the air gap component 3. The air gap component 3 is integrated on the upper mounting base 1, rather than on the faucet. Therefore, regardless of the type of faucet used, as long as it can be installed through the through-hole 11 of the base, the air gap function of the base can be used to observe the wastewater. This breaks the dependence on dedicated faucets with integrated air gaps, realizes the function of the base integrating air gaps, meets the requirements of different water purifiers to observe the wastewater discharge, meets the installation and use requirements of more types of faucets, and thus improves the versatility of use.

[0038] Based on the above technical solution, optionally, in order to facilitate the fixed connection of the upper mounting base 1 and the lower locking base 2 together, so as to meet the requirements of installation on the table.

[0039] In one embodiment, the upper mounting base 1 and the lower locking base 2 can be connected by conventional bolt fastening. Specifically, the upper mounting base 1 is provided with a through hole, and the lower locking base 2 is provided with a bolt hole. The locking bolt is inserted into the through hole and threaded into the bolt hole.

[0040] In another embodiment, such as Figures 4-5 As shown, the upper mounting base 1 is provided with a locking hole 12, and a protruding anti-retraction part 13 is provided in the locking hole 12; The base with air gap function also includes a connector 5, the lower end of which is connected to the lower locking seat 2. The connector 5 is inserted into the locking hole 12 and abuts against the anti-reverse part 13. The anti-reverse part 13 is configured to restrict the connector 5 from sliding downward in the locking hole 12.

[0041] Specifically, the faucet is fixedly installed on the countertop in the user's home by a base with an air gap function. In order to meet the installation requirements of the base with an air gap function, the countertop is usually provided with mounting holes.

[0042] In the actual assembly process, the base with air gap function needs to be fixedly installed on the table first.

[0043] Specifically, the lower locking seat 2 extends under the tabletop through the mounting hole, and is suspended under the tabletop by the connecting piece 5; then, the upper end of the connecting piece 5 passes through the locking hole 12, and as the connecting piece 5 is pulled up, the distance between the lower locking seat 2 and the upper mounting seat 1 gradually decreases, and finally, the tabletop is sandwiched between the lower locking seat 2 and the upper mounting seat 1.

[0044] Since the anti-reverse part 13 can restrict the connector 5 from sliding down in the locking hole 12, in actual operation, the operator pulls the connector 5 upward so that the connector 5 passes through the locking hole 12 and moves upward until the lower locking seat 2 is against the lower surface of the table. After the lower locking seat 2 is against the lower surface of the table, the lower locking seat 2 and the upper mounting seat 1 can clamp the table under the cooperation of the connector 5 and the anti-reverse part 13.

[0045] Since the connector 5 is restricted by the locking hole 12 and the stop part 13, it will not move downward in the opposite direction without external force. In this way, after the locking seat under the countertop is tightened by the connector 5, the locking seat can be made to fit tightly against the lower surface of the countertop. Then, the operator can install the faucet body 6 on the base with air gap function in the conventional faucet installation method. Since there is no need to keep pulling the connector 5 by hand, the operation convenience is improved and the installation efficiency of the faucet is improved.

[0046] After the connector 5 is pulled up so that the tabletop is clamped between the upper mounting base 1 and the lower locking base 2, the connector 5 is restrained by the anti-reverse part 13 in the locking hole 12, so that the lower locking base 2 cannot pull the connector 5 under its own weight. The anti-reverse part 13 always plays a role, so the operator does not need to pull the connector 5 with extra force to prevent the lower locking base 2 from falling. This ensures that the connector 5 will not slide down from the locking hole 12 under the restraint of the anti-reverse part 13, which greatly reduces the difficulty of operation.

[0047] After the upper mounting base 1 and the lower locking base 2 are fixedly connected, the faucet is installed on the base with air gap function. The specific installation method can be adopted according to the structure of the faucet body 6 using the existing installation connection method, which will not be restricted or elaborated here.

[0048] In one embodiment, in order to more reliably fix and support the lower locking seat 2 at the bottom via the upper mounting seat 1, the base with air gap function includes two connecting members 5, and the upper mounting seat 1 is provided with two locking holes 12, with the through opening 11 located between the two locking holes 12.

[0049] Specifically, in order to improve the connection reliability between the lower locking seat 2 and the upper mounting seat 1, two connectors 5 can be used to connect the lower locking seat 2 and the upper mounting seat 1 together. After the two connectors 5 are inserted into the corresponding locking holes 12 and tightened in place, the lower locking seat 2 can be fixed to the upper mounting seat 1 by the two connectors 5.

[0050] In one embodiment of this application, the physical form of the anti-retraction part 13 can adopt a variety of different structural forms.

[0051] In one embodiment, the anti-retraction part 13 is an elastic claw, the lower end of the elastic claw is disposed on the hole wall of the locking hole 12, the elastic claw extends obliquely from bottom to top, and the upper end of the elastic claw forms an anti-retraction space with the hole wall of the locking hole 12; the connecting member 5 passes through the anti-retraction space.

[0052] Specifically, the anti-reverse part 13 adopts the structure of an elastic claw. The lower end of the elastic claw is set on the hole wall of the locking hole 12. The elastic claw extends obliquely from bottom to top. Its upper end and the hole wall of the locking hole 12 form an anti-reverse space so as to lock the connector 5 through the elastic claw.

[0053] The inclined extension design of the elastic claws allows the connector 5 to pass through the stop space more easily during insertion, thanks to the elastic deformation characteristics of the claws. When the connector 5 moves upward, the elastic claws remain against the connector 5 due to their elasticity, preventing it from sliding downward.

[0054] The engaging structure formed between the elastic claw and the connector 5 provides a continuous and stable anti-reverse force during installation. If the connector 5 tends to slide downwards in the locking hole 12, the inclined elastic claw will apply greater pressure to the connector 5 to prevent it from slipping out.

[0055] In another embodiment, the anti-retraction part 13 is an anti-retraction protrusion that protrudes from the wall of the locking hole 12, and an anti-retraction space is formed between the anti-retraction protrusion and the wall of the locking hole 12; the connector 5 passes through the anti-retraction space.

[0056] Specifically, the anti-reverse part 13 is an anti-reverse protrusion formed on the wall of the locking hole 12. The anti-reverse protrusion protrudes from the wall of the locking hole 12. During the process of inserting the connector 5 into the locking hole 12 and pulling it upward, the connector 5 forms an interference fit with the anti-reverse space. Therefore, the connector 5 can only move by overcoming the friction generated by contact with the anti-reverse protrusion when the pulling force applied by the operator reaches a certain level. The pulling force applied by the operator is usually much greater than the weight of the lower locking seat 2. Therefore, after the operator releases the connector 5, the connector 5 will not slip out of the locking hole 12 under the action of the weight of the lower locking seat 2 itself.

[0057] In one embodiment, the surface of the anti-reverse portion 13 that contacts the connector 5 is provided with multiple tooth structures.

[0058] Specifically, in order to improve the locking reliability of the anti-reverse part 13 to the connector 5, a toothed structure can be provided on the surface of the anti-reverse part 13213. In this way, when pressure is applied to the connector 5 through the anti-reverse part 13 to limit the slippage of the connector 5, the toothed structure can be tightly locked on the surface of the connector 5, and more effectively prevent the connector 5 from slipping.

[0059] In one embodiment, the surface of the connector 5 that contacts the anti-reverse portion 13 is provided with a plurality of racks, and the plurality of racks are arranged side by side along the length direction of the connector 5.

[0060] Specifically, connector 5 has multiple toothed strips on its surface. These strips can cooperate with the toothed structure to achieve a more effective anti-slip design. For example, similar to the anti-reverse design of cable ties, when connector 5 is pulled upwards, the toothed strips can pass over the toothed structure to ensure a smooth pull of connector 5; while when connector 5 is pulled downwards, the toothed strips will lock onto the toothed structure to prevent slippage.

[0061] In another embodiment of this application, the physical form of the connector 5 can also have various structural forms. For example, the connector 5 is a flat strip. The flat strip structure of the connector 5 allows the operator to easily adjust the position of the lower locking seat 2 under the table, making it easier to adjust the position of the lower locking seat 2. When two connectors 5 are used, the width of the flat strip used in the connectors 5 can be the same or different, and there is no limitation here.

[0062] In addition, after the upper mounting base 1 and the lower locking base 2 are pre-assembled together by means of connector 5, the part of connector 5 that extends beyond the upper mounting base 1 can be cut off to avoid affecting the installation of the faucet.

[0063] In some embodiments, a gasket 21 is also provided on the upper surface of the lower locking seat 2.

[0064] Specifically, by providing a gasket 21 on the lower locking seat 2, after the lower locking seat 2 is tightened, the gasket 21 is sandwiched between the lower locking seat 2 and the lower surface of the table, thereby improving the stability of the installation.

[0065] In one embodiment, the lower locking seat 2 is provided with a connecting hole 22, and the bottom of the connector 5 is provided with an anti-detachment plug 51. The connector 5 passes through the connecting hole 22, and the anti-detachment plug 51 abuts against the bottom of the lower locking seat 2.

[0066] Specifically, during the assembly of the connector 5 and the lower locking seat 2, the connector 5 passes through the connecting hole 22 from the bottom. Since the size of the anti-detachment plug 51 is larger than the connecting hole 22, it ensures that the connector 5 lifts and supports the lower locking seat 2.

[0067] This application also provides a faucet, including a faucet body 6, the lower end of which is provided with a threaded extension section 61, and also includes the aforementioned base with air gap function; the threaded extension section 61 passes through the through-hole 11 and is threadedly connected to the threaded hole 23 on the lower locking seat 2.

[0068] Specifically, the lower end of the faucet body 61 is provided with a threaded extension section 6111, which extends downward; the lower locking seat 2 is also provided with a threaded hole 23, and the upper mounting seat 1 is provided with a through opening 11, through which the threaded extension section 61 passes and is threadedly connected to the threaded hole 23.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
