Description

Technical Field

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

[0002] With the increasing functionality of bathroom products, more and more faucets are adopting built-in sensor switches to control water purification equipment, lighting, and other devices. The structure typically involves fixing the sensor switch to the faucet body and attaching a trigger to the valve core or handle to activate it. For example, Chinese patent CN207569244U discloses a faucet with a quick-discharge indicator, where a sensor hole is set in the main body, the sensor tube is placed inside the hole and connected to the circuit board, and a magnet is configured to rotate together with the ceramic disc and valve core rod. This design requires not only a sensor hole within the faucet body but also an assembly component to fix the sensor tube, resulting in a complex internal structure that hinders sensor tube disassembly and maintenance, and makes it difficult to share with other faucet products. Furthermore, during use, it has been found that this type of sensor structure has a lag between the magnetic triggering of the sensor switch and the handle's control of the valve core, leading to problems such as excessive pressure on the valve core and delayed indicator lights. Utility Model Content

[0003] This utility model discloses a sensor faucet, which aims to improve the problems of complex structure and lag in sensing of existing sensor faucets.

[0004] The present invention adopts the following solution:

[0005] A sensor-operated faucet includes a body, a valve core, a pressure cap, a mounting base, and a sensor module. The sensor module includes a first sensor mounted on a handle or a valve core shaft and a second sensor disposed on the mounting base. The first sensor triggers the second sensor when the handle or valve core shaft rotates synchronously to the sensing position. The valve core is disposed within the valve cavity of the body via the pressure cap. The body and / or the pressure cap are provided with a positioning part, and the mounting base is provided with a limiting part. The limiting part engages with the positioning part to limit the mounting base circumferentially, and to ensure that the deflection angle of the first sensor rotating to the sensing position is less than the deflection angle of the valve core shaft rotating to the working position.

[0006] As a further improvement, the mounting base is provided with multiple limiting parts. By selecting different limiting parts to connect with the positioning part, the position of the second sensing element relative to the positioning part can be adjusted, so that the deflection angle of the first sensing element to the sensing position is adjustable.

[0007] As a further improvement, the first sensing element is fixedly connected to the valve core shaft, and the mounting base is annularly sleeved on the outside of the valve core, with multiple limiting parts arranged in an array along the circumferential direction.

[0008] As a further improvement, the positioning part is configured as a groove symmetrically arranged along the inner wall of the valve cavity, and the limiting part is a rib protruding along the outer wall of the mounting base.

[0009] As a further improvement, the mounting base is provided with at least two mounting cavities, and the second sensing element is configured to be assembled in one of the mounting cavities.

[0010] As a further improvement, the mounting cavity has an opening extending from the bottom surface of the mounting base to the side surface, and the second sensor is configured to be embedded upward from the bottom surface of the mounting base into the mounting cavity for a limiting position, so that the wiring of the second sensor can extend along the opening and pass through the bottom of the body.

[0011] As a further improvement, the second sensing element includes an assembly end, which is embedded in the mounting cavity and is configured to resemble the mounting cavity.

[0012] As a further improvement, the handle includes a wear-resistant part, a decorative part, and a handle. The wear-resistant part is fixedly connected to the valve core shaft and abuts against the mounting seat to limit the mounting seat axially. The decorative part is sleeved on the wear-resistant part and is connected to and limited by the wear-resistant part via the handle.

[0013] As a further improvement, the positioning part is configured to protrude along the top or side of the cover, and the limiting part is an assembly groove located inside the mounting base.

[0014] As a further improvement, the body has a main body extending vertically and an assembly portion protruding along the side wall of the main body. The water-passing assembly is configured to be inserted into the main body along the axial direction of the body. A valve chamber communicating with the main body is formed in the assembly portion. The valve core is disposed in the valve chamber and is pressed against the water-passing assembly via the pressure cap, thereby limiting the water-passing assembly.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] This application mounts a first sensor on a handle or valve core shaft, allowing it to rotate synchronously with the handle or valve core shaft and trigger a second sensor when it reaches the sensing position. Simultaneously, the second sensor is mounted on a mounting base and connected to a positioning part via a limiting part. This ensures that the angle at which the first sensor deflects to the sensing position is less than the angle at which the valve core shaft rotates to the working position, thus triggering the second sensor before the valve core shaft reaches the working position and avoiding problems caused by sensing lag. The mounting base offers high compatibility and is minimally affected by the valve core and body structure. It can be easily and quickly removed for replacement, maintenance, or when the second sensor is not needed. Furthermore, eliminating the need for additional structures on the body, valve core, or handle for mounting the second sensor further improves the compatibility of the sensing structure, reduces development costs, and shortens the development cycle.

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. Example

[0039] Combination Figures 1 to 9This embodiment provides a sensor faucet, including a body 1, a valve core 4, a pressure cap 6, a mounting base 2, and a sensing module. The sensing module includes a first sensing element 31 mounted on the handle or valve core shaft 41 and a second sensing element 32 disposed on the mounting base 2. The first sensing element 31 is triggered when the handle or valve core shaft 41 rotates synchronously to the sensing position. The valve core 4 is disposed in the valve cavity 12 of the body 1 via the pressure cap 6. The body 1 and / or the pressure cap 6 are provided with a positioning part 11, and the mounting base 2 is provided with a limiting part 21. The limiting part 21 engages with the positioning part 11 to limit the mounting base 2 circumferentially, and to make the deflection angle of the first sensing element 31 rotating to the sensing position less than the deflection angle of the valve core shaft 41 rotating to the working position.

[0040] For example, the valve core shaft 41 needs to rotate 90° to reach the working position. If the first sensing element 31 deflects 90° with the valve core shaft 41 before reaching the sensing position to trigger the second sensing element 32, a sensing lag problem will occur. In this embodiment, the limiting part 21 can engage with the positioning part 11 to change the relative position of the second sensing element 32, so that the first sensing element 31 can deflect 45° to reach the sensing position, and will not exceed the sensing critical point when the valve core shaft 41 reaches the working position. This achieves early triggering of the second sensing element 32, so that external devices electrically connected to the second sensing element 32 can start in advance or synchronously when the valve core shaft 41 reaches the working position, thereby avoiding problems caused by delay or lag. In another embodiment, the mounting base 2 is provided with multiple limiting parts 21. By selecting different limiting parts 21 to connect with the positioning part 11, the position of the second sensing element 32 relative to the positioning part 11 can be adjusted, so that the deflection angle of the first sensing element 31 to the sensing position is adjustable. Researchers can calculate the deflection angle based on the lag time obtained from experiments, and then select the corresponding limiting part 21 to engage with the positioning part 11 to adjust the second sensing element 32 to the desired position, thereby adjusting the deflection angle of the first sensing element 31 triggering the second sensing element 32. Preferably, the first sensing element 31 can be a magnet, and the second sensing element 32 can be a Hall element to improve the sensing effect; however, this is not a limitation and is not specifically imposed.

[0041] It should be noted that in this embodiment, the first sensing element 31 is disposed on the handle or valve core shaft 41 so that the first sensing element 31 can rotate synchronously with the handle or valve core shaft 41 and trigger the second sensing element 32 when it rotates to the sensing position. Simultaneously, the second sensing element 32 is disposed on the mounting base 2 and connected to the positioning part 11 via the limiting part 21, so that the angle at which the first sensing element 31 deflects to the sensing position is less than the deflection angle at which the valve core shaft 41 rotates to the working position. This ensures that the second sensing element 32 is triggered before the valve core shaft 41 reaches the working position, thereby avoiding problems caused by sensing lag. Furthermore, by selecting different limiting parts 21 to adjust the position of the second sensing element 32, the sensing structure can adapt to different sensing lag times. The mounting base 2 has high compatibility and is less affected by the structure of the valve core 4 and the body 1. When replacing, repairing, or when the second sensing element 32 is no longer needed, the mounting base 2 can be removed, which is convenient and quick. This eliminates the need for additional structures on the body 1, valve core 4, or handle for assembling the second sensing element 32, thereby further improving the compatibility of the sensing structure, reducing the development cost of the sensing structure, and shortening the development cycle.

[0042] In a preferred embodiment, the body 1 has a valve cavity 12, and the mounting base 2 is disposed within the valve cavity 12. The positioning part 11 is a groove symmetrically arranged along the inner wall of the valve cavity 12, and the limiting part 21 is a rib protruding along the outer wall of the mounting base 2. During assembly, the desired limiting part 21 is inserted along the groove, so that the mounting base 2 is circumferentially limited. Further, the first sensing element 31 is fixedly connected to the valve core shaft 41 so as to rotate synchronously with the valve core shaft 41. The mounting base 2 is annularly sleeved on the outside of the valve core 4, and multiple limiting parts 21 are arranged in an array along the circumferential direction. For example, eight ribs are arranged in an array along the outer circumference of the mounting base 2, that is, the included angle between two adjacent ribs is 45°. The positioning part 11 is set as two symmetrically arranged grooves to ensure that the mounting base 2 will not rotate during use, ensuring the assembly stability of the mounting base 2. In other embodiments, other numbers or different included angles of ribs can also be provided to achieve more angle adjustments.

[0043] Based on the above embodiments, in an optional embodiment of this utility model, the mounting base 2 is provided with at least two mounting cavities 22, and the second sensing element 32 is configured to be assembled in one of the mounting cavities 22. The mounting cavity 22 increases the adjustment range of the deflection angle to adapt to different product requirements, and also facilitates the routing of the wiring 322 of the second sensing element 32. In one embodiment, the mounting cavity 22 has an opening 221 extending from the bottom surface of the mounting base 2 to the side surface. The second sensing element 32 is configured to be embedded upwards from the bottom surface of the mounting base 2 into the mounting cavity 22 for limiting, so that the wiring 322 of the second sensing element 32 can extend along the opening 221 and pass through the bottom of the body 1. This ensures that the wiring 322 of the second sensing element 32 always faces the bottom of the body 1 and can pass through the bottom of the body 1, avoiding tangling of the wiring 322 and simplifying the sensing structure. Preferably, the second sensing element 32 includes an assembly end 321, which is embedded in the mounting cavity 22 and is similar in shape to the mounting cavity 22, so that the second sensing element 32 and the mounting cavity 22 can be detachably connected, facilitating the installation, replacement and maintenance of the second sensing element 32. The circuit principle and circuit structure between the second sensing element 32 and the external device are existing technologies and will not be described in detail here.

[0044] In another embodiment, the handle includes a wear-resistant part 51, a decorative part 52, and a handle 53. The wear-resistant part 51 is fixedly connected to the valve core shaft 41 and abuts against the mounting base 2 to limit the axial movement of the mounting base 2. The decorative part 52 is sleeved on the wear-resistant part 51 and is connected and limited to the wear-resistant part 51 via the handle 53. For example, the valve core shaft 41 is provided with screw holes. One end of the wear-resistant part 51 is fastened to the valve core shaft 41 by screws, and the other end abuts against the mounting base 2. The side wall of the wear-resistant part 51 is provided with an assembly hole, and the handle 53 is provided with a thread that is adapted to connect with the assembly hole. During installation, the handle 53 is inserted into the assembly hole from the side wall of the decorative part 52 and is threadedly connected and fixed to the assembly hole, thereby limiting the movement of the decorative part 52. In one embodiment, refer to Figure 10 and Figure 11 The wear-resistant part 51 has a mounting hole 511 on its inner side, and the first sensing element 31 is embedded in the mounting hole 511. When the handle 53 is operated, the wear-resistant part 51 is driven to rotate synchronously, so that the first sensing element 31 can reach the sensing position to trigger the second sensing element 32. By placing the first sensing element 31 on the wear-resistant part 51, the problem of valve core 4 being incompatible with other valve cores can be avoided. Furthermore, the deflection angle of the first sensing element 31 reaching the sensing position can be adjusted by adjusting the mounting angle of the wear-resistant part 51. In other embodiments, the first sensing element 31 can also be disposed on the decorative part 52 or the handle 53.

[0045] Based on the above embodiments, in an optional embodiment of this utility model, a valve core 4 is disposed in the valve cavity 12. The valve core 4 is connected and limited to the water-passing assembly 7 via a pressure cap 6. The end of the pressure cap 6 away from the water-passing assembly 7 is provided with an operating part 61 for driving the pressure cap 6 to rotate. For example, the pressure cap 6 is sleeved on the valve core 4 and is provided with a threaded part 62 for connecting with the water-passing assembly 7. The mounting seat 2 is sleeved on the pressure cap 6, with one end abutting against the pressure cap 6 and the other end abutting against the wear-resistant part 51. During assembly, the positioning pin on the valve core 4 is inserted into the positioning hole 71 on the water-passing assembly 7 for limitation, and then the pressure cap 6 is sleeved on the valve core 4. The operating part 61 is driven to rotate by hand or jig so that the threaded part 62 on the pressure cap 6 is tightened with the thread on the water-passing assembly 7, thereby pressing the valve core 4 and the water-passing assembly 7 together. Next, insert the mounting base 2 along the positioning part 11, then connect the wear-resistant part 51 to the valve core shaft 41, then insert the decorative part 52, and finally connect the handle 53 to the wear-resistant part 51. The assembly is simple and the disassembly is convenient. In particular, the pressure cap 6 is connected to the water-passing component 7 instead of the main body 1, which simplifies the structure of the main body 1 and further improves the compatibility of the structure.

[0046] In a preferred embodiment, the positioning part 11 is formed as a protrusion along the top or side of the pressure cover 6, and the limiting part 21 is an assembly groove provided inside the mounting base. Figure 12 and Figure 13 The operating part 61 can also serve as a positioning part. The mounting base 2 is annular and sleeved on the outside of the pressure cover 6. Its limiting part 21 is configured as a slot for engaging with the operating part 61. Multiple operating parts 61 are arranged in an array along the top of the pressure cover 6. Engaging the slot with the operating part 61 limits the position of the mounting base 2. During installation, by selecting to engage with the operating part 61 at different positions, the position of the second sensing element 32 relative to the first sensing element 31 can be adjusted, further improving the compatibility of the sensing structure. In another embodiment, combined with Figure 14 The positioning part 11 is a limiting strip protruding along the side wall of the pressure cap 6, the mounting base 2 is a C-shaped ring, and the limiting part 21 is a plurality of assembly grooves that fit the limiting strip along the inner wall of the mounting base 2. Figure 15 Alternatively, a tight fit method can be used, where the mounting base 2 is adjusted to the required angle and then directly fitted onto the pressure cap 6 to limit the position of the mounting base 2. This method is not limited to this and no specific limitation is made.

[0047] In other embodiments, the body 1 has a vertically extending main body portion 13 and an assembly portion 14 protruding along the side wall of the main body portion 13. The water-passing assembly 7 is configured to be inserted into the main body portion 13 along the axial direction of the body 1. A valve cavity 12 communicating with the main body portion 13 is formed in the assembly portion 14. The valve core 4 is disposed in the valve cavity 12 and is pressed against the water-passing assembly 7 via the pressure cap 6, thereby limiting the water-passing assembly 7. In this embodiment, the valve core 4 is connected to the water-passing assembly 7 so that the body 1 does not need to be provided with a water passage structure, which simplifies the structure of the body 1 and allows the appearance of the body 1 to be unrestricted by the water passage structure. This also means that the appearance of the faucet can be more diverse. At the same time, the water-passing assembly 7 is directly connected to the pressure cap 6 so that other structures besides the body 1 can be used on other bodies 1, thereby improving the versatility of the structure, reducing development costs, accelerating development speed, and enhancing market competitiveness. It should be noted that the valve core shaft 41 and the internal structure of the valve core 4, such as the connection structure between the ceramic plates and the working principle, are existing technologies and will not be described in detail here.

[0048] 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.
