Description

Technical Field

[0001] This utility model relates to the field of bathroom product technology, and more specifically, to a double swing arm faucet structure. Background Technology

[0002] As people's demands for water quality increase, more and more families are starting to use water filters. To facilitate water use and save installation space, dual-outlet faucets that can connect to both raw water and filtered water (purified water) are commonly used. Their structure is mostly similar to a purified water faucet disclosed in Chinese Patent CN204664495U, including a main body and an outlet head mounted on the main body. The main body has a raw water inlet path and a filtered water inlet path, while the outlet head has a raw water outlet and a purified water outlet. A raw water switch controls the connection between the raw water inlet path and the raw water outlet, and a filtered water switch controls the connection between the filtered water inlet path and the purified water outlet. However, since both outlets are located on a single outlet head, when both inlets are open simultaneously, the filtered water and raw water can easily mix, causing inconvenience to the user. Furthermore, the angles of the two outlets cannot be adjusted independently, which is also disadvantageous for the user. Utility Model Content

[0003] This utility model discloses a double swing arm faucet structure, which aims to improve the problems of existing double-outlet faucets being prone to water mixing and the inability to independently adjust the outlet angle.

[0004] The present invention adopts the following solution: A double-swing-arm faucet structure includes a main body, a first swing arm, and a second swing arm. The first swing arm has a purified water outlet connected to a purified water circuit, and the second swing arm has a raw water outlet connected to a raw water circuit. A connector is mounted or formed on the main body. The first swing arm is sleeved on the top of the connector, and the second swing arm is sleeved on the bottom or middle of the connector. At least one slot is formed on the side wall of the connector, and the inlet pipe of at least one swing arm passes through the slot, thereby restricting or preventing the rotation of the swing arm.

[0005] As a further improvement, the first swing arm and the second swing arm are configured to be parallel vertically to each other and perpendicular to the axis of the main body.

[0006] As a further improvement, a clean water inlet pipe is provided inside the first swing arm, and a raw water inlet pipe is provided inside the second swing arm. Both the clean water inlet pipe and the raw water inlet pipe are fixed to the swing arm with screws.

[0007] As a further improvement, the purified water inlet pipe is configured to be inserted into the first swing arm from top to bottom, and the raw water inlet pipe is configured to be inserted into the second swing arm from bottom to top. The connector extends upward from the bottom end with a relief groove communicating with the slot, so that the raw water inlet pipe can be inserted into the slot along the relief groove.

[0008] As a further improvement, an embedding part is formed on the groove walls on both sides of the relief groove, and a receiving groove is provided on the main body. The embedding part is configured to be inserted into the receiving groove from top to bottom so as to engage and limit the receiving groove.

[0009] As a further improvement, the connector is provided with a channel through which the water supply pipe passes, and the inlet ends of the two water inlet pipes are staggered.

[0010] As a further improvement, the main body is provided with a positioning hole inside, and a flexible hose for connecting to the water purification inlet pipe passes through the positioning hole.

[0011] As a further improvement, a first sealing ring is fitted between the outer wall of the connector and the inner wall of the first swing arm, and a second sealing ring is fitted between the outer wall of the connector and the inner wall of the second swing arm, so that the first swing arm and the second swing arm have a damping feel during rotation.

[0012] As a further improvement, a protrusion is provided along the inner wall of the second swing arm, and a limiting groove is provided on the connector to fit the protrusion, thereby limiting the rotation angle of the second swing arm.

[0013] As a further improvement, a first limiting part is provided on the inner wall of the first swing arm, and a second limiting part is provided on the top of the connector. The first limiting part and the second limiting part cooperate to limit the rotation angle of the first swing arm.

[0014] As a further improvement, a first locking part is provided along the inner wall of the first swing arm, and a second locking part is provided on the connector. The first locking part and the second locking part engage to limit the first swing arm along the axial direction.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects: 1. This application utilizes a double-swing arm design to allow independent adjustment of the water outlet angles of the purified water outlet and the raw water outlet. When both outlets are dispensing water simultaneously, the angle of the swing arms can be adjusted to increase the misalignment distance between the two outlets, thus preventing water mixing and facilitating user operation. Both swing arms can rotate around the main body, meeting user needs in various scenarios. Furthermore, a connecting component allows for a rotatable connection between the two swing arms and the main body, simplifying the structure and saving costs. The slotted design not only restricts or prevents the swing arm rotation but also reduces structural space, minimizing the vertical distance between the second and first swing arms and ensuring the overall dimensions of the faucet are maintained.

[0016] 2. The first and second swing arms are arranged parallel to each other vertically and perpendicular to the axis of the main body to make the faucet's appearance simpler and further ensure the faucet's height dimensions. Users can manually move the corresponding swing arms to adjust the angle of the water outlet according to their needs, creating different faucet shapes in the process. This diversifies the faucet's design, allowing it to adapt to different installation spaces or decoration styles, thus enhancing the faucet's market competitiveness.

[0017] 3. The connector extends upward from the bottom end with a relief groove that communicates with the slot, so that the raw water inlet pipe can be inserted into the slot along the relief groove, thereby facilitating the installation of the raw water inlet pipe. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

The terms “first,” “second,” etc., are only used to distinguish different objects and should not be construed as indicating or implying relative importance or the quantity, specific order, or primary or secondary relationship of the indicated technical features. The term “several” means one or more, and “multiple” means two or more, unless otherwise explicitly specified. Example

[0023] Combination Figures 1 to 12 This embodiment provides a double-swing-arm faucet structure, including a main body 1, a first swing arm 2, and a second swing arm 3. The first swing arm 2 is provided with a purified water outlet 21 connected to the purified water circuit, and the second swing arm 3 is provided with a raw water outlet 31 connected to the raw water circuit. A connector 11 is installed or formed on the main body 1. The first swing arm 2 is sleeved on the top of the connector 11, and the second swing arm 3 is sleeved on the bottom or middle of the connector 11. At least one slot 111 is opened on the side wall of the connector 11, and the water inlet pipe of at least one swing arm passes through the slot 111, thereby limiting the rotation angle of the swing arm.

[0024] For example, purified water is water filtered through a filter, and raw water is municipal tap water. The flow of purified water is controlled by a purified water valve, and the flow of raw water is controlled by a raw water valve. The purified water valve and the raw water valve can be either solenoid valves or ceramic valves, without specific limitations.

[0025] It should be noted that in this embodiment, by setting up double swing arms, the water outlet angles of the purified water outlet 21 and the raw water outlet 31 can be adjusted independently. When water flows from both outlets simultaneously, the angle of the swing arms can be adjusted to increase the misalignment distance between the two outlets, thereby preventing water mixing and facilitating user operation. Both swing arms can rotate around the main body 1, meeting the user's needs in different scenarios. Furthermore, the rotatable connection between the two swing arms and the main body 1 can be achieved by setting up the connector 11, resulting in a simple structure and cost savings. The slot 111 not only restricts or prevents the rotation of the swing arms but also reduces structural space, thereby decreasing the vertical distance between the second swing arm 3 and the first swing arm 2, thus ensuring the overall size of the faucet.

[0026] In a preferred embodiment, the first swing arm 2 and the second swing arm 3 are arranged vertically parallel to each other and perpendicular to the axis of the main body 1, so as to make the appearance of the faucet simpler and further ensure the height of the faucet. Users can manually move the corresponding swing arms to adjust the angle of the water outlet according to their needs. In this process, different faucet shapes can be formed, so as to diversify the faucet's appearance and adapt to different installation spaces or decoration styles, thereby enhancing the faucet's market competitiveness.

[0027] Furthermore, referring to Figure 5 The rotation radius of the purified water outlet 21 is greater than that of the second swing arm 3. This means that regardless of the positions of the first and second swing arms 2 and 3, water flowing from the purified water outlet 21 will not splash onto the second swing arm 3, preventing water contamination and splashing, and ensuring a positive user experience. Furthermore, the first swing arm 2 is positioned higher than the second swing arm 3 so that the purified water outlet 21 is higher than the raw water outlet 31, preventing the purified water outlet 21 from being sprayed by raw water or splashed by wastewater.

[0028] Based on the above embodiments, in an optional embodiment of this utility model, a purified water inlet pipe 22 is disposed inside the first swing arm 2, and a raw water inlet pipe 32 is disposed inside the second swing arm 3. Both the purified water inlet pipe 22 and the raw water inlet pipe 32 are fixed to the swing arm by screws. Preferably, the purified water inlet pipe 22 is arranged to be inserted into the first swing arm 2 from top to bottom, and the raw water inlet pipe 32 is arranged to be inserted into the second swing arm 3 from bottom to top. The connector 11 extends upward from the bottom end with a relief groove 112 communicating with the slot hole 111, so that the raw water inlet pipe 32 can be inserted into the slot hole 111 along the relief groove 112, thereby facilitating the installation of the raw water inlet pipe 32. Exemplarily, the first swing arm 2 includes a top cover. During installation, the purified water inlet pipe 22 is first locked to the first swing arm 2, and then the top cover is pressed in. The connection structure between the top cover and the first swing arm 2 can be a snap-fit ​​structure. Similarly, the second swing arm 3 includes a lower cover. During installation, first lock the raw water inlet pipe 32 to the second swing arm 3, and then press the lower cover in. This makes disassembly and assembly convenient and facilitates installation and maintenance.

[0029] Furthermore, embedding portions 119 are formed on the groove walls on both sides of the relief groove 112, and the main body 1 is provided with a receiving groove 14. The embedding portions 119 are configured to be inserted into the receiving groove 14 from top to bottom to engage and limit their position with the receiving groove 14. The wall surface of the receiving groove 14 provides support for the embedding portions 119, thereby preventing deformation of the groove walls on both sides of the relief groove 112 and avoiding the problem of failure of the connector 11.

[0030] It should be mentioned that, in one embodiment, the slot 111 serves as a limiting device, and the second swing arm 3 engages with the slot 111 via a raw water inlet pipe 32 passing through the slot 111, thereby limiting the rotation angle of the second swing arm 3. In another embodiment, refer to... Figure 11 and Figure 12 The slot 111 serves as a clearance feature. A protrusion 33 is provided on the inner wall of the second swing arm 3, and a limiting groove 118 is provided on the connector 11 to fit the protrusion 33, thereby limiting the rotation angle of the second swing arm 3. The limiting groove 118 includes an annular segment arranged circumferentially along the connector 11 and a vertical segment extending from the bottom surface of the connector 11 to communicate with the annular segment. During installation, the protrusion 33 can be inserted vertically into the annular segment, but this is not limited to this and is not specifically restricted.

[0031] In one embodiment, the connector 11 has a channel 113 through which the water supply pipe passes, and the inlet ends of the two water inlet pipes are staggered to facilitate connection between the two water inlet pipes and their corresponding water pipes, making the structural space more compact. For example, the rotation center of the purified water inlet pipe 22 is offset to the left relative to the center of the main body 1, and the rotation center of the raw water inlet pipe 32 is offset to the right relative to the center of the main body 1. Furthermore, the main body 1 has a positioning hole 13 inside, and the flexible hose 221 for connecting to the purified water inlet pipe 22 passes through the positioning hole 13 to reduce the problem of pipe entanglement when the swing arm rotates.

[0032] In another embodiment, the connector 11 has a plurality of first mounting holes 114, and the inner wall of the main body 1 has a second mounting hole 12 corresponding to each of the first mounting holes 114. The first mounting holes 114 and the second mounting holes 12 are locked together by fasteners. The fasteners are preferably screws, to facilitate the assembly and disassembly of the connector 11, and to simplify the connection structure between the connector 11 and the main body 1. Preferably, referring to… Figure 13 and Figure 14 A first sealing ring 11A is fitted between the outer wall of the connector 11 and the inner wall of the first swing arm 2, and a second sealing ring 11B is fitted between the outer wall of the connector 11 and the inner wall of the second swing arm 3, so that the first swing arm 2 and the second swing arm 3 have a damping feel during rotation, thereby improving the rotation feel of the swing arms. For example, the outer wall of the connector 11 is provided with a first sealing groove 11C and a second sealing groove 11D, with the first sealing ring 11A fitted in the first sealing groove 11C and the second sealing ring 11B fitted in the second sealing groove 11D. However, this is not the only possibility; in other embodiments, multiple sealing rings may be fitted.

[0033] Based on the above embodiments, in an optional embodiment of this utility model, a first limiting part 23 is protruding from the inner wall of the first swing arm 2, and a second limiting part 115 is provided on the top of the connecting member 11. The first limiting part 23 and the second limiting part 115 cooperate to limit the rotation angle of the first swing arm 2. For example, the second limiting part 115 is an arc shape protruding along the top surface of the connecting member 11, and the first limiting part 23 is located in a position without the second limiting part 115. When the first swing arm 2 rotates, the first limiting part 23 and the second limiting part 115 abut against each other to limit the rotation angle of the first swing arm 2. Preferably, a first locking part 24 is provided along the inner wall of the first swing arm 2, and a second locking part 116 is provided on the connecting member 11. The first locking part 24 and the second locking part 116 engage to limit the first swing arm 2 axially. The two locking parts can be a snap-fit ​​structure, which is not specifically limited.

[0034] In other embodiments, the connector 11 is provided with wear-resistant pads 117 for engaging with the first swing arm 2 and the second swing arm 3. Specifically, two layers of wear-resistant pads 117 are provided between the bottom end of the first swing arm 2 and the second swing arm 3, and two layers of wear-resistant pads 117 are also provided between the second swing arm 3 and the main body 1. The wear-resistant pads 117 are arranged in a ring shape and fitted around the outside of the connector 11, thereby reducing wear on the swing arms during rotation and ensuring the lifespan of the faucet. Preferably, the wear-resistant pads 117 are made of POM and are designed to be concealed by the outer surface to ensure the aesthetics of the faucet.

[0035] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
