Description

Technical Field

[0001] This utility model relates to the field of bathroom fixtures, and in particular to a sensor nozzle device and a urinal. Background Technology

[0002] The current design of sensor-operated urinal nozzles faces a dual conflict between aesthetics and functionality. Due to the aesthetic requirements of the overall urinal design, the nozzle's dimensions must be strictly controlled; an excessively large size would disrupt the visual harmony of the bathroom product. However, the nozzle's internal components, such as the sensor module, flow guiding structure, and water passage, require integration, and limited installation space makes structural layout difficult.

[0003] Traditional induction modules are installed by inserting from the front flange 2 of the nozzle body 1 backwards, and then covering it with the front cover 5. Their size is directly limited by the size of the pre-drilled hole at the upper end of flange 2. In practical applications, because the flow guiding assembly 3 occupies a large space in the radial direction of the nozzle, the space of the pre-drilled hole is limited, making it impossible to meet the installation requirements of the induction module 4 (which integrates sensing circuits and drive circuits, etc.). See [link / reference] Figure 15 The existing solution forces the circuit module inside the sensing module 4 to be split into two independent circuit boards (sensing circuit board and driving circuit board), which are then encapsulated with potting compound and connected with waterproof terminals. Although this solves the installation problem, it increases the module cost and adds complexity to the assembly process. Utility Model Content

It proposes a sensor nozzle device and urinal that changes the installation direction of the sensor module so that the size of its fixing part is not limited by the size of the reserved hole. This significantly improves the utilization rate of the installation space of the sensor module and reduces costs without increasing the overall size of the nozzle.

[0005] The present invention adopts the following technical solution:

The outer periphery of the body also has a mounting groove. The sensing end of the sensing module is inserted obliquely from above the mounting groove and passes through the mounting hole. The fixed end of the sensing module is embedded in the mounting groove and fixedly engaged with it.

[0007] The mounting groove is recessed along the vertical axis of the main body; the sensing module is located on the outside of the main body and its fixed end has a protrusion, which is embedded in the mounting groove.

[0008] It includes two mounting grooves located on both sides of the radial direction of the main body; the fixed end of the sensing module is provided with two protrusions, which are respectively embedded in the corresponding two mounting grooves.

[0009] A first locking part is provided on the side wall of the mounting groove; a second locking part is provided on the side wall opposite to the protrusion and the first locking part, and the second locking part is engaged with the first locking part to achieve a fixed fit.

[0010] A step is provided on the side of the body where the sensing module is located. The step is located on the side of the fixed end of the sensing module away from the sensing end. The fixed end of the sensing module abuts against the step to achieve limit.

[0011] The size of the mounting hole is larger than the size of the sensing end of the sensing module so that the sensing end can be inserted at an angle and pass through; the flow guiding component is provided with an axially penetrating positioning hole at the mounting hole position, and the positioning hole is adapted to the sensing end of the sensing module to achieve positioning.

[0012] The main body has a flow guide section at the end where the flow guide component is located, which extends radially away from the mounting hole; the flow guide component is provided with a flow guide plate, which is fixed relative to the main body and forms a water outlet channel with the flow guide section; a positioning hole is provided at the opposite mounting hole of the flow guide plate.

[0013] The flow guiding component is provided with two adjusting members, which are rotatably disposed in the water outlet channel. The two adjusting members can move towards or away from each other to adjust the water outlet amplitude at the water outlet end of the water outlet channel.

[0014] It also includes a front cover, which is placed outside the flow guide assembly and fixed relative to the main body. The front cover is also provided with a limit hole, and the side of the sensing end of the sensing module away from the fixed end is embedded in the limit hole.

[0015] The sensing module includes a circuit board, a housing, and a sensing cover; the housing has a receiving cavity with an opening; the circuit board is located inside the sensing cavity and is provided with a sensing circuit and a driving circuit, the sensing element of the sensing circuit is located near the opening of the circuit board, and the driving circuit is located at the end of the circuit board away from the opening; the sensing cover covers the sensing element and is fixed relative to the housing.

[0016] A urinal, the urinal body having a urinal bowl and an assembly hole on the upper side wall of the urinal bowl; it also includes the urinal body and a sensor nozzle device, the urinal body being fixedly inserted through the assembly hole.

[0017] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0018] 1. In this utility model, by optimizing the installation structure design of the sensing module and adopting an assembly method in which the sensing end is inserted at an angle into the mounting hole and fixedly fitted with the mounting groove, the size of the fixed end of the sensing module is no longer limited by the diameter of the mounting hole. This design effectively improves the utilization rate of internal space while maintaining the overall compactness of the nozzle structure, simplifies the assembly process, and reduces costs.

[0019] 2. In this utility model, the sensing module has a protrusion at the fixed end that fits into the mounting groove, which enables the sensing module to be quickly positioned. The second locking part and the first locking part are engaged to further achieve a fixed fit between the fixed end and the mounting groove.

[0020] 3. In this utility model, a step is provided in the main body. By abutting the fixed end face of the sensing module with the step, an axial limiting structure is formed, which not only provides a reliable axial positioning reference for the sensing module, but also avoids over-positioning of the fixed end during installation.

[0021] 4. In this invention, the inner diameter of the mounting hole is designed to be larger than the outer diameter of the sensing end, allowing the sensing end to be smoothly inserted at an inclined angle. Simultaneously, a positioning hole adapted to the sensing end is provided at the corresponding position of the flow guiding component to prevent shaking. The combined effect of these two design elements simplifies the assembly process and ensures accurate positioning. This design, together with the mounting groove and stepped portion, constitutes a multi-dimensional positioning structure, ensuring the stability of the sensing module installation while improving the overall reliability of the device.

[0022] 5. In this utility model, the front cover is provided with an axially penetrating limiting hole corresponding to the sensing end, so that the sensing end can be accurately embedded therein. The cooperation between the limiting hole and the sensing end forms a third positioning point, which, together with the clearance fit of the mounting hole at the front end and the positioning hole of the flow guide component, constitutes a three-point positioning structure. This not only retains the operational convenience of tilt installation, but also significantly improves the overall installation stability and positional accuracy of the sensing module through multi-level positioning.

[0023] 6. In this utility model, since the size of the fixed end of the sensing module is no longer limited by the diameter of the mounting hole, the sensing module can integrate the sensing circuit and the driving circuit. The overall structure simplifies the assembly process and reduces costs while maintaining the compactness of the nozzle. Attached Figure Description

[0041] The present invention will be further described below through specific embodiments.

[0042] See Figures 1 to 13A sensing nozzle device includes a body 10, a flow guiding component 20, and a sensing module 30. The body 10 is a tubular structure with an axially extending water inlet channel 11. The flow guiding component 20 is located at one axial end of the body 10, i.e., the flow guiding component 20 is installed at the water outlet end of the water inlet channel 11 and forms a water outlet channel 21 therewith, which connects to the water inlet channel 11 for water discharge. The end face of the end where the flow guiding component 20 is located of the body 10 has a mounting hole 12 that extends radially away from the water outlet channel 21 and is axially extending. The mounting hole 12 and the water outlet channel 21 are located in different regions of the radial space of the end face of the body 10. The outer periphery of the body 10 is also provided with a mounting groove 13, which extends axially. The sensing end 31 of the sensing module 30 is inserted obliquely from above the mounting groove 13 and passes through the mounting hole 12, and the fixing end 32 of the sensing module 30 is embedded in the mounting groove 13 and fixedly engaged therewith.

[0043] This invention optimizes the installation structure design of the sensing module 30 by employing an assembly method in which the sensing end 31 is inserted at an angle into the mounting hole 12 and fixedly engaged with the mounting groove 13. This eliminates the limitation of the size of the fixed end 32 of the sensing module 30 on the diameter of the mounting hole 12. This design effectively improves the utilization of internal space while maintaining the overall compactness of the nozzle structure, simplifies the assembly process, and reduces costs.

[0044] In this design, the mounting groove 13 on the body 10 is recessed inward along the axial direction perpendicular to the body 10. The sensing module 30 is located outside the body 10, and its fixed end 32 has a protrusion 33. The protrusion 33 is a structure that protrudes outward relative to the body 10. The sensing module 30 is fixed outside the body 10 by the protrusion 33 being embedded in the mounting groove 13. In practical applications, the number of mounting grooves 13 and protrusions 33 can be set according to requirements. For example, there can be one mounting groove 13 and one protrusion 33, or two or more mounting grooves 13 and protrusions 33. In the figure, taking two mounting grooves 13 and two protrusions 33 as an example, the two mounting grooves 13 are located on both sides of the radial direction of the body 10; the fixed end 32 of the sensing module 30 is correspondingly provided with two protrusions 33, which are respectively embedded in the corresponding two mounting grooves 13, thereby achieving radial positioning of the sensing module 30.

[0045] Furthermore, to ensure a secure installation between the fixed end 32 of the sensing module 30 and the main body 10, a first locking portion 14 is provided on the side wall of the mounting groove 13. The first locking portion 14 is a protruding rib structure that extends outward from the opposite side wall, and the rib extends axially. A second locking portion 34 is correspondingly provided on the side wall opposite the protrusion 33 and the first locking portion 14. The second locking portion 34 is also a protruding rib structure that extends axially. The top side of the second locking portion 34 abuts against the bottom side of the first locking portion 14 to achieve a fixed fit. In practical applications, the locking fit between the first locking portion 14 and the second locking portion 34 can also be achieved using a concave-convex fit between the groove and the rib.

[0046] A step portion 15 is provided on the side of the main body 10 where the sensing module 30 is located. The step portion 15 is located on the side of the fixed end 32 of the sensing module 30 away from the sensing end 31. By abutting the end face of the fixed end 32 of the sensing module 30 with the step portion 15, an axial limiting structure is formed. The step portion 15 provides a reliable axial positioning reference for the sensing module 30 and avoids over-positioning of the fixed end 32 during installation.

[0047] In this invention, the size of the mounting hole 12 is larger than the size of the sensing end 31 of the sensing module 30. That is, the inner diameter of the mounting hole 12 is designed to be slightly larger than the outer diameter of the sensing end 31 of the sensing module 30. This size fit allows the sensing end 31 to be smoothly inserted into and pass through the mounting hole 12 at an inclined angle. The flow guiding component 20 is provided with an axially penetrating positioning hole 22 at the mounting hole 12. The positioning hole 22 is adapted to the sensing end 31 of the sensing module 30 to achieve positioning. That is, the inner diameter of the positioning hole 22 is adapted to the outer diameter of the sensing end 31. The inner diameter of the positioning hole 22 is smaller than the inner diameter of the mounting hole 12 to prevent the sensing module 30 from shaking. On the one hand, the clearance fit between the mounting hole 12 and the sensing end 31 provides the necessary operating space for tilt installation, significantly reducing the assembly difficulty; on the other hand, the fit between the positioning hole 22 and the sensing end 31 ensures the accuracy of the final positioning of the sensing end 31, and together with the mounting groove 13 and the step portion 15, it forms a multi-dimensional positioning structure, which not only ensures the installation stability of the sensing module 30, but also ensures the accuracy of the sensing angle, thereby improving the overall reliability of the device.

[0048] Specifically, the flow guiding component 20 of the main body 10 has a flow guiding portion 16 extending radially away from the mounting hole 12. The flow guiding component 20 is provided with a flow guiding plate 23, which is fixed to the main body 10 by fasteners. There is a gap between the flow guiding plate 23 and the flow guiding portion 16 to form a water outlet channel 21. A positioning hole 22 is provided at the mounting hole 12 of the flow guiding plate 23. This positioning hole 22 forms a mating relationship with the sensing end 31 of the sensing module 30 to achieve positioning. The structure of the water outlet channel 21 can realize the directional guidance of water flow. At the same time, the setting of the positioning hole 22 ensures the accurate positioning of the sensing module 30 without affecting the normal function of the water outlet channel 21.

[0049] In addition to the flow guide plate 23 and positioning hole 22 related to the installation of the sensing module 30, the flow guide component 20 of this utility model may also include an adjustment structure. This adjustment structure is disposed within the water outlet channel 21 and is used to adjust the water outlet amplitude at the outlet end of the water outlet channel 21. This adjustment structure can be implemented using two adjusting members 24, which are rotatably disposed within the water outlet channel 21. The two adjusting members 24 can move towards or away from each other to adjust the water outlet amplitude at the outlet end of the water outlet channel 21. In practical applications, the two adjusting members 24 can be implemented using common structures. For example, the ends of the two adjusting members 24 that are close to each other are rotatably connected to the flow guide portion 16, and the other ends are close to the outlet end of the water outlet channel 21. Two gears mesh to drive the transmission. By controlling the rotation of one adjusting member 24, the other adjusting member 24 is driven to move in the opposite direction, thereby driving the two adjusting members 24 to move towards or away from each other, thus adjusting the water outlet amplitude at the outlet end of the water outlet channel 21.

[0050] See Figure 4 The adjustment structure can also be configured such that one end of two adjustment components 24 is coaxially disposed in the water inlet channel 21 and rotatably connected thereto, and the other end of the two adjustment components is connected to a transmission structure. The transmission structure is located on the side of the guide vane 23 opposite to the water outlet channel 21 and adopts a gear meshing structure. By controlling one of the adjustment components 24 to rotate, the other adjustment component 24 is driven to move in the opposite direction under the transmission structure 25, thereby driving the two adjustment components 24 to move towards or away from each other.

[0051] Furthermore, it also includes a front cover 40, which covers the flow guide assembly 20 and is fixed relative to the main body 10. The front cover 40 is also provided with a limiting hole 41, which is also axially through. The position of the limiting hole 41 corresponds to the sensing end 31 of the sensing module 30, so that the side of the sensing end 31 away from the fixed end 32 can be accurately inserted into the limiting hole 41. The cooperation between the limiting hole 41 and the sensing end 31 forms a positioning structure, which, together with the mounting hole 12 and the positioning hole 22, constitutes a three-point positioning system, significantly improving the overall installation stability of the sensing module 30.

[0052] The sensing module 30 includes a circuit board 35, a housing 36, and a sensing cover 37. The housing 36 has a receiving cavity 36a and a protrusion 33. The receiving cavity 36a has an opening, and the opening and protrusion 33 are located at opposite ends of the housing 36 along its axial direction; the end with the opening is the sensing end 31, and the end with the protrusion 33 is the fixed end 32. The circuit board 35 is located inside the sensing cavity and contains a sensing circuit and a driving circuit. The sensing element 38 of the sensing circuit is located near the opening on the circuit board 35, and the driving circuit is located at the end of the circuit board 35 away from the opening. The sensing cover 37 covers the sensing element 38 and is fixed relative to the housing 36. A sealing element 39 can also be provided between the sensing element 38 and the sensing cover 37 to achieve a waterproof seal. The sensing module 30 uses an existing integrated sensing circuit and driving circuit module, eliminating the need for component disassembly and saving costs.

[0053] When installing the sensing module 30 of this utility model, firstly, the sensing end 31 of the sensing module 30 is aligned at an inclined angle with the mounting hole 12 on the body 10, so that the sensing end 31 passes through the mounting hole 12. Then, the posture of the sensing module 30 is adjusted so that the protrusion 33 of the fixed end 32 is accurately embedded into the corresponding mounting groove 13 on the outer side of the body 10. At this time, the second locking part 34 of the protrusion 33 and the first locking part 14 of the side wall of the mounting groove 13 form an axial locking fit to achieve radial fixation. During this process, the end face of the fixed end 32 of the sensing module 30 abuts against the stepped part 15 of the body 10 to form an axial limit. At the same time, after the sensing end 31 passes through the mounting hole 12, it is inserted into the positioning hole 22 of the flow guide assembly 20 to achieve positioning. Finally, the front cover 40 is installed so that the distal end of the sensing end 31 is embedded into the limiting hole 41 of the front cover 40, which, together with the mounting hole 12 and the positioning hole 22, forms a three-point positioning system, completing the installation of the sensing module 30.

[0054] This utility model adopts an assembly method of tilting the insertion into the mounting hole 12, so that the size of the fixed end 32 is no longer limited by the diameter of the mounting hole 12. The sensing module 30 can integrate the sensing circuit and the driving circuit. The overall structure simplifies the assembly process and reduces costs while maintaining the compactness of the nozzle.

[0055] Based on this, the present invention also proposes a urinal, including a urinal body 50 and a sensor nozzle device. The urinal body 50 is provided with a urinal bowl 51, and an assembly hole is provided at a suitable position on the upper side wall of the urinal bowl 51. The body 10 of the sensor nozzle device passes through the assembly hole and is locked in place with a washer 52, a rubber pad 53 and a nut 54.
