Description

Technical Field

[0001] This utility model relates to the field of kitchen and bathroom products technology, specifically to a sensor faucet structure that is easy to install and maintain quickly. Background Technology

[0002] In kitchen and bathroom products, sensor faucets are widely used due to their convenience of providing water without contact. Traditional sensor faucets typically consist of two main functional components: the water flow path and the sensor controller. Installation and maintenance require separate operations on each part, making the process cumbersome. Furthermore, different countries have varying requirements for the materials used in faucets and other products, such as low lead content and microbial control, leading to differences in the water flow design of faucets from different exporting countries, further complicating production design. In addition, the installation and fixation of existing sensor modules largely rely on fasteners, which need to be exposed or concealed with rubber parts, affecting aesthetics and increasing manufacturing costs. Utility Model Content

[0003] Therefore, this utility model proposes a sensor faucet structure that is easy to install and maintain quickly.

[0004] To address the aforementioned technical problems, this utility model provides the following technical solution:

[0005] A sensor-operated faucet includes: a faucet body, wherein a water inlet pipe is provided inside the faucet body, and a water outlet connector is provided at the water outlet end of the water inlet pipe, the water outlet connector being detachably connected to the faucet body via a fastening assembly; an aerator located inside the faucet body, the aerator being connected to the water outlet connector via an installation module; and a sensor module located inside the faucet body, the sensor module being inserted and positioned onto the installation module.

[0006] In some embodiments of this utility model, the installation module includes an installation housing and a rotating connecting sleeve rotatably connected to the installation housing, the rotating connecting sleeve being threadedly connected to the water outlet connector.

[0007] In some embodiments of this utility model, a portion of the rotating connecting sleeve extends to the outside of the mounting housing, and the rotating connecting sleeve is connected to the mounting housing by an elastic clamp.

[0008] In some embodiments of this utility model, the water outlet connector and the rotating connecting sleeve are sealed together by a sealing ring.

[0009] In some embodiments of this utility model, the rotating connecting sleeve is provided with an internal hexagonal positioning part suitable for use with an internal hexagonal wrench on the side away from the water outlet connector.

[0027] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0030] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] Please see Figures 1-9 This invention provides a specific embodiment of a sensor-operated faucet. The faucet includes a faucet body 1, within which a water inlet pipe 2 is installed. The outlet end of the water inlet pipe 2 is connected to a water outlet connector 3, which is detachably connected to the faucet body 1 via a fastening assembly 4. Since different countries have different certification requirements for the materials of water-contaminated products, this separate design of the faucet body 1 and the water inlet pipe 2 allows for flexible selection of the materials for both components according to national standards, thereby meeting certification requirements. Because the faucet body 1 does not come into contact with water, it can be made of a lower-cost metal material; while the water inlet pipe 2 can be made of a flexible material that meets the safety requirements for water-contaminated products. Furthermore, the water outlet connector 3 is detachably connected to the faucet body 1 via the fastening component 4. This allows for reliable installation and fixation of the water inlet pipe 2 and the faucet body 1, and also facilitates the installation and fixation of the aerator 5 and the sensing module 6, which will be described later. Ultimately, this results in the faucet's appearance being free of any traces of fastening connections, effectively improving its anti-disassembly coefficient. This ensures both aesthetics and enhances the product's safety and stability.

[0032] like Figure 3 As shown, the aforementioned sensor faucet also includes an aerator 5 and a sensor module 6 installed inside the faucet body 1. The aerator 5 is detachably connected to the mounting module 7, and the sensor module 6 is inserted and positioned on the mounting module 7 to form an integrated assembly, which is then connected to the water outlet connector 3 through the mounting module 7. The aerator 5 and sensor module 6 integrated inside the faucet adopt a modular design, which allows for simultaneous installation and maintenance. Compared with the complex operation of traditional faucets that require disassembling the entire faucet structure, this design significantly reduces maintenance time and labor costs.

[0033] Specifically, the sensing module 6 features a waterproof sensing housing 61. The housing 61 employs a sealed design and has a special coating that provides corrosion resistance, wear resistance, and oxidation resistance, effectively preventing the intrusion of external water flow, moisture, and dust. Internally, it integrates a high-precision integrated circuit board equipped with advanced signal sensing and processing chips. Through precisely laid-out circuit traces, it achieves rapid capture and accurate analysis of external sensing signals. The sensing module 6 also includes a connection line. One end of this line connects to the signal output port on the integrated circuit board, while the other end connects to the control circuit through a pre-set wiring channel within the faucet body 1. This wiring channel is sealed to effectively prevent water flow and moisture intrusion, avoiding damage from moisture and ensuring the stability and reliability of signal transmission from the sensing module 6.

[0034] Specifically, such as Figure 1 , Figure 2 As shown, the faucet body 1 has an overall L-shaped tube structure. Its vertically extending tube portion forms the faucet column 11, which is connected to the faucet mounting surface. The free end of its horizontally extending tube portion 12 (i.e., the outlet side of the faucet body 1) extends downward to form a spout 13. The water outlet connector 3, the mounting module 7, the aerator 5, and the sensing module 6 are all installed in the inner area of ​​the spout 13.

[0035] Specifically, in one alternative implementation, such as Figures 6-8 As shown, the installation module 7 includes an installation housing 71 and a rotating connecting sleeve 72 rotatably connected within the installation housing 71. The rotating connecting sleeve 72 is threadedly connected to the water outlet connector 3. In actual installation, by controlling the rotation of the rotating connecting sleeve 72, the threaded connection and disassembly with the water outlet connector 3 can be easily achieved, making the operation simple and efficient.

[0036] Specifically, in one alternative implementation, such as Figure 6 As shown, a portion of the rotating connecting sleeve 72 extends to the outside of the mounting housing 71. The rotating connecting sleeve 72 is connected to the mounting housing 71 by an elastic clamp 73 located on the sleeve and outside the mounting housing 71. The elastic clamp 73 ensures that the rotating connecting sleeve 72 is reliably connected to the mounting housing 71, ensuring that the structure of the mounting module 7 remains stable and reliable even when subjected to external forces such as water flow impact during long-term use.

[0037] Specifically, such as Figure 8As shown, the water outlet connector 3 and the rotating connecting sleeve 72 are sealed together by a sealing ring 9. The sealing ring 9 effectively prevents water leakage from the connection between the water outlet connector 3 and the rotating connecting sleeve 72, ensuring the sealing of the water flow path, improving the waterproof performance of the sensor faucet, and extending the product's service life. More specifically, the sealing ring 9 is made of food-grade silicone rubber and is embedded in the annular sealing groove of the rotating connecting sleeve 72 by an interference fit.

[0038] Specifically, in one alternative implementation, such as Figure 7 , Figure 8 As shown, the rotating connecting sleeve 72 has an internal hexagonal locating part 721 on the side away from the water outlet connector 3. This internal hexagonal locating part 721 is adapted to be used with an internal hexagonal wrench. When installing or removing the rotating connecting sleeve 72, maintenance personnel can use the internal hexagonal wrench in conjunction with the internal hexagonal locating part 721 to provide a stable and precise point of force application, making the rotation operation more labor-saving and convenient, and enabling more efficient completion of related installation and maintenance work.

[0039] Specifically, in one alternative implementation, such as Figure 3 As shown, the mounting housing 71 has a mounting cavity 713 on the side away from the water outlet connector 3. The aerator 5 is detachably connected to the mounting cavity 713 of the mounting housing 71. For example, the aerator 5 and the mounting housing 71 are connected by a threaded connection or a snap-fit ​​connection, so that the aerator 5 is embedded in the mounting housing 71. The installation and replacement of the aerator 5 are extremely convenient. When the aerator 5 is blocked or damaged, the maintenance personnel can disassemble the aerator 5 separately for cleaning, repair or replacement, which greatly reduces the maintenance cost and difficulty and improves the maintainability of the product.

[0040] Specifically, such as Figure 7 , Figure 8 As shown, the outer wall of the component formed after the mounting housing 71 and the sensing module 6 are inserted and positioned matches the inner wall of the spout 13. That is, the component formed by the mounting housing 71 and the sensing module 6 abuts against the inner wall of the spout 13. For example, the inner wall of the spout 13 is formed with a circular cross-section, and the component formed after the mounting housing 71 and the sensing module 6 are inserted and positioned is roughly cylindrical. This matching design makes the structure of the entire sensor faucet more compact and reasonable, which not only improves the overall appearance of the product, but also enhances the tightness and stability of the connection between the components, so that the sensor faucet can still maintain a good working condition under working environments such as water flow impact.

[0041] The following section will be combined with the appendix Figures 6-9The insertion and positioning structure of the sensing module 6 and the mounting module 7 is described in detail. Specifically, the sides of the mounting housing 71 and the sensing housing 61 that cooperate with each other have at least two positioning structures to achieve positioning in at least two directions and prevent relative movement between the two.

[0042] One of the positioning structures includes positioning stepped surfaces respectively disposed on the mounting housing 71 and the sensing housing 61, namely a first positioning stepped surface 711 and a second positioning stepped surface 611. The first positioning stepped surface 711 and the second positioning stepped surface 611 cooperate to limit the relative position of the mounting housing 71 and the sensing housing 61 along the installation direction. The installation direction refers to the installation direction of the component formed by the sensing module 6 and the mounting module 7 relative to the faucet body 1, that is... Figure 7 The arrow H is shown in the direction.

[0043] Another positioning structure includes a positioning groove 712 provided on the mounting housing 71 and a positioning protrusion 612 provided on the sensing housing 61 (see Figure 9 The positioning groove 712 and the positioning protrusion 612 cooperate with each other to limit the relative position of the mounting shell 71 and the sensing shell 61 along the direction perpendicular to the installation direction, that is, in the circumferential direction. This further precisely limits the installation position of the sensing shell 61 from multiple dimensions, ensuring the stability and accuracy of the installation of the sensing module 6. It avoids the problem of positional deviation between the sensing module 6 and the mounting module 7 during installation, which would lead to the component being unable to be installed reliably. At the same time, this positioning structure can also ensure that the sensing module 6 is reliably fixed inside the faucet body 1 in the working state, thereby ensuring the stable operation of its sensing function.

[0044] The installation process for the above-mentioned sensor faucet is as follows:

[0045] First, assemble the faucet body 1 and the water inlet pipe 2: (as follows) Figure 4 , Figure 5 As shown, the water inlet pipe 2 is inserted into the faucet body 1 along the faucet post 11 until the water outlet end of the water inlet pipe 2 extends to the area close to the spout 13. The water outlet connector 3 is then inserted into the outlet of the water inlet pipe 2 and installed on the connection hole inside the faucet body 1 by two bolts 4, so as to achieve a reliable connection and fixation between the water inlet pipe 2 and the faucet body 1.

[0046] Installation module 7 is integrated with sensor module 6: (e.g.) Figure 7As shown, the mounting housing 71 of the mounting module 7 and the sensing housing 61 of the sensing module 6 are assembled into an integrated component after being inserted and positioned. This component is then embedded into the spout 13 of the faucet body 1. An Allen wrench is then inserted into the Allen positioning part 721 of the rotating connecting sleeve 72. As the Allen wrench rotates, the threaded area of ​​the rotating connecting sleeve 72 begins to engage with the threaded area of ​​the water outlet connector 3. Because the elastic clamp fixes the relative position of the rotating connecting sleeve 72 and the mounting housing 71, the rotation of the Allen wrench causes the mounting module 7 and the sensing module 6 to move upwards as a whole, and the upper end face of the rotating connecting sleeve 72 contacts the limiting plane of the water outlet connector 3. At this time, the O-ring fitted on the water outlet connector 3 is also squeezed into the rotating connecting sleeve 72, forming a seal on the water inlet connector assembly (see...). Figure 8 The above installation method allows for the simultaneous assembly of two components.

[0047] Install aerator 5: After the installation module 7 and sensor module 6 are integrated and installed, use the aerator key to screw the aerator 5 in until the rubber gasket on the upper surface of the aerator 5 is sealed by pressure. At this point, the installation of the water outlet component of the sensor faucet assembly is complete (see [link]). Figure 2 ).

[0048] Connect the sensor faucet with the water outlet assembly installed to the mounting holes on the countertop or sink via connector 8, and tighten to the standard torque to complete the installation.

[0049] The disassembly process of the above-mentioned sensor faucet is as follows:

[0050] First, use the aerator key to rotate in the opposite direction to remove the aerator 5. Then, use an Allen wrench to rotate the hexagonal locating part 721 of the rotating connecting sleeve 72 in the opposite direction. The threaded area of ​​the rotating connecting sleeve 72 will gradually disengage from the threaded area of ​​the water outlet connector 3, and the integrated assembly formed by the mounting module 7 and the sensing module 6 can be separated from the faucet body 1. If you want to replace the water inlet pipe 2, continue to remove the fastening screws 4 and take out the water outlet connector 3 from the water outlet 13 of the faucet body 1. During the entire disassembly process, functional parts such as the aerator 5, sensing module 6, water inlet pipe 2, and water outlet connector 3 can all be removed and installed from the water outlet 13 of the faucet body 1 without disassembling other parts such as the faucet column 11.

[0051] Throughout the installation and maintenance process, only the water outlet connector 3 is secured by two bolts 4. The rest of the components are secured using the external structure of the installation module 7 and the sensing module 6, and then connected by threads to the water outlet connector 3. Finally, after screwing in the aerator 5, all internal fastening components are hidden inside the aerator 5. The appearance is simple and beautiful, with no trace of any fastening connections, and no need for concealing them with rubber pads or other unsightly materials.

[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
