The expansion structure assembly 3 includes an expansion structure member 31 and a screw 32 arranged on the expansion structure member 31. By tightening the screw 32, the opposite side walls 313 and 314 of the expansion structure member 31 are relatively expanded (that is, the relative distance between them becomes larger) to respectively press against the rear wall of the sensing probe 2 and the cavity wall of the installation cavity 11 (such as Figure 3 As shown), the sensing probe 2 is thereby fixed in the mounting cavity 11.

[0034] During assembly, the expansion structure assembly 3 only needs to be placed between the rear wall of the sensing probe 2 and the wall of the mounting cavity 11 (such as Figure 2 As shown), then tighten the screw 32 on the expansion structure assembly 3 with a screwdriver, so that the opposite side walls 313 and 314 on the expansion structure 31 can be expanded and stretched, thereby tightening the rear wall of the sensing probe 2 and the cavity wall of the installation cavity 11 (as shown). Figure 3 As shown), the fixed installation of the sensing probe 2 is completed, which has a simple structure, convenient assembly, high efficiency, low cost, and is suitable for large-scale assembly line operations.

[0035] In this specific embodiment, the expansion structure 31 includes a first end 311, a second end 312 and two expansion side walls 313 and 314, the two expansion side walls 313 and 314 are both elastic, the first end 311 and the second end 312 are arranged opposite to each other, the first ends of the two expansion side walls 313 and 314 are respectively connected to the two sides of the first end 311, and the second ends of the two expansion side walls 313 and 314 are respectively connected to the two sides of the second end 312 to form an annular structure, the first end 311 is provided with a through hole 3111, the second end 312 is provided with a screw hole 3121, the threaded end of the screw 32 passes through the through hole 3111 and is screwed into the screw hole 312, and by tightening the screw 32, the first end 311 and the second end 312 can be brought close to each other, so that the two expansion side walls 313 and 314 expand outward. The expansion structure 31 is simple in structure, easy to implement, and low in cost, but is not limited to this.

[0036] Furthermore, in this embodiment, the two expansion side walls 313 and 314 are also respectively provided with grooves 3131 and 3141 extending toward the first end 311 and the second end 312, which are used to make way for some components arranged in the installation cavity 11 to avoid the expansion structure assembly 3 affecting the installation of other components, making the structure more compact and the design more convenient.

[0037] In this specific embodiment, the expansion structure 31 can be made of elastic plastic or elastic rubber by integral injection molding, which is easy to implement and has low cost, but is not limited thereto.

[0038] In this specific embodiment, the sensing probe 2 can be various sensing probes such as an infrared probe, a microwave probe, etc.

[0039] In this specific embodiment, the faucet body 1 is roughly in a "7" shape, and the sensing probe 2 is arranged at the lower end of the faucet body 1, but it is not limited to this. In other embodiments, the shape of the faucet body 1 can be designed according to actual needs.

[0040] In this specific embodiment, a mounting base is also included. The faucet body 1 is arranged on the mounting base. The mounting base includes a joint 4 for passing through the mounting hole. A removable mounting hole rubber plug 5 is sleeved on the outside of the joint 4. The outer diameter of the mounting hole rubber plug 5 is larger than the outer diameter of the joint 4. In this specific embodiment, the outer diameter Φ of the joint 4 is 24 mm, and the outer diameter Φ of the mounting hole rubber plug 5 is 34 mm.

[0041] During installation, if the plumber makes no mistake when drilling the hole, he will drill a Φ25mm mounting hole, then remove the mounting hole plug 5, and extend the connector 4 (with an external thread) from the mounting table top through the mounting hole to under the mounting table top, and then lock and fix it with the nut 41. For more details, please refer to the existing countertop faucet installation process, which will not be described in detail here.

[0042] If the plumber does not read the instructions carefully when drilling the hole, and habitually drills a Φ35mm installation hole, the installation hole plug 5 can be set on the joint 4, and then the joint 4 can be extended from the installation table through the installation hole to under the installation table. The installation hole plug 5 is located in the installation hole and then locked and fixed with the nut 41. This perfectly solves the problem of the sensor faucet assembly shaking and being unstable after installation due to drilling the wrong hole.

The quick-connect joint 8 is used for easy installation and improved assembly efficiency.

[0044] Preferably, in the present embodiment, the quick-connect connector 8 is a pneumatic plug-in connector, which is easy to install and reliable in pressure resistance, and can prevent the problem of water leakage caused by the locking structure of the screw thread of an ordinary induction faucet.

[0045] In this specific embodiment, a control panel and a liquid extraction component are provided in the control box 6, the induction probe 2 is connected to the control panel via a signal line 22, the control end of the liquid extraction component is connected to the control panel, the liquid inlet of the liquid extraction component is connected to the liquid bottle 9, and the liquid outlet of the liquid extraction component is connected to the liquid outlet on the control box 6. The specific structure of the control panel and the liquid extraction component can refer to the existing induction soap dispenser faucet, which will not be described in detail.

[0046] Further, in this embodiment, a hanging piece 7 is further provided at the rear of the control box 6 for fixing the control box 6, such as fixing it on a wall, and the hanging piece 7 and the control box 6 are detachably arranged. By providing a detachable hanging piece 7, the installation of the control box 6 is facilitated and the use is convenient.

[0047] In this specific embodiment, the rear portion of the control box 6 is provided with a hook 61, and the hanger 7 is provided with a clamping portion 72. The hanger 7 is detachably connected by being clamped in the hook 61 by the clamping portion 72. The structure is simple and the disassembly and assembly are convenient. However, this is not limited to this. In other embodiments, other existing detachable structures can also be used to achieve this.

[0048] The hanger 7 is provided with a mounting hole 71. During installation, firstly, an expansion screw 73 (but not limited to this, in other embodiments, other fixing parts such as screws) is passed through the mounting hole 71 and then fixed on a mounting surface such as a wall. Then, the hook 61 is hooked on the clamping part 72 to complete the fixed installation of the hanger 7. The operation is convenient and the installation efficiency is improved.

[0049] Embodiment 2

[0050] like Figure 7-10 As shown, the difference between this embodiment and the first embodiment is that the expansion structure 31′ of this embodiment is different from the expansion structure 31 of the first embodiment. Specifically, in this embodiment, the expansion structure 31′ includes a first end 311′, a second end 312′, a fixed side plate 313′ and an expansion side wall 314′. The first end 311′ is fixedly connected to the fixed side plate 313′, the second end 312′ is slidably disposed on the fixed side plate 313′ and can move relative to the first end 311′, the expansion side wall 314′ is respectively connected to the first end 311′ and the second end 312′, the fixed side plate 313′ faces the rear wall of the sensing probe 2, and the expansion side wall 314′ faces the cavity wall of the installation cavity 11, the first end 311′ is provided with a through hole 3111′, the second end 312′ is provided with a screw hole 3121′, and the threaded end of the screw 32 passes through the through hole 3111′ and is screwed into the screw hole 3121′.

[0051] During assembly, the expansion structure assembly 3 only needs to be placed between the rear wall of the sensing probe 2 and the wall of the mounting cavity 11 (such as Figure 7 As shown), the screw 32 on the expansion structure assembly 3 is then tightened with a screwdriver, the second end 312′ of the expansion structure 31′ moves toward the first end 311′, and the expansion side wall 314′ expands (i.e., the relative distance from the fixed side plate 313′ increases), so that the fixed side plate 313′ presses against the rear wall of the sensing probe 2, and the expansion side wall 314′ presses against the cavity wall of the mounting cavity 11, thereby fixing the sensing probe 2 in the mounting cavity 11, and during the tightening process of the screw 32, the fixed side plate 313′ will not be deformed, and the fixed side plate 313′ has a large contact area with the sensing probe 2, and has better stability.

[0052] Preferably, in this specific embodiment, a limiting groove 3131 ′ for limiting the sensing probe 2 is provided on the surface of the fixed side plate 313 ′ opposite to the rear wall of the sensing probe 2. When the fixed side plate 313 ′ is pressed against the rear wall of the sensing probe 2, the rear wall of the sensing probe 2 is embedded in the limiting groove 3131 ′ to be limited and fixed, and is not easy to move, thereby improving stability.

[0053] Preferably, in this specific embodiment, the expansion side wall 314′ is also provided with a groove 3141′ extending toward the first end 311′ and the second end 312′, which is used to make way for some components arranged in the installation cavity 11 to prevent the expansion structure assembly 3 from affecting the installation of other components, making the structure more compact and the design more convenient.

[0054] The present invention adopts an expansion structure component to fix the sensing probe. During assembly, the expansion structure component only needs to be placed between the rear wall of the sensing probe and the cavity wall of the installation cavity, and then the screws on the expansion structure component are tightened with a screwdriver, so that the expansion side wall on the expansion structure can be opened, thereby tightening the rear wall of the sensing probe and the cavity wall of the installation cavity to complete the fixing of the sensing probe. The structure is simple, the assembly is convenient, the efficiency is high, the cost is low, and it is suitable for large-scale assembly line operations.

[0055] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
