Description

Technical Field

[0001] The invention relates to the field of faucets, in particular to a faucet with a sensor. Background Art

[0002] Existing faucets with sensors (usually infrared sensors) are commonly used because of their convenience. According to different design requirements, the sensor is installed at different positions of the faucet. Common faucets used on basins usually have the sensor nested on the outer wall of the tubular water outlet seat so that gestures can be accurately collected. In order to achieve the nested installation of the sensor on the outer wall of the faucet's water outlet seat, the existing technical means usually adopt the following methods:

[0003] A, see Figure 1 and Figure 2 As shown, a mounting through hole 61' is provided on the tubular water outlet seat 6, and a threaded hole is provided on one side of the inner wall of the water outlet seat 6 corresponding to the peripheral side of the mounting through hole 61'. The sensor 2' is provided with an ear plate 24 with a mounting hole matching the threaded hole. After the sensor 2' is nested in the mounting through hole 61' of the water outlet seat 6, the ear plate 24 is locked in the threaded hole on the inner wall of the water outlet seat 6 located on the peripheral side of the mounting through hole 61' by bolts 9, so that the sensor 2' is nested and installed on the outer wall of the tubular water outlet seat 6. However, since the inner cavity space of the water outlet seat 6 is relatively narrow and it is difficult to operate with general tools, a water outlet seat 6 with a manual valve mounting hole (such as the water outlet seat shown in CN201827484U) is usually selected, and the sensor mounting through hole 61' is provided at a position directly opposite to the valve core mounting hole 62 of the water outlet seat 6, so that when the valve core is not installed, the tool can be inserted from the valve core mounting hole 62 to lock the sensor 2', and then the valve core is installed. But obviously, this technical means is bound to have the technical defect of difficult installation, and at the same time, the installation position of the sensor 2 ′ has limited room for selection.

[0004] B. A mounting through hole is opened on the tubular water outlet seat, and a frame-shaped slot is arranged on the inner wall side of the water outlet seat corresponding to the surrounding side of the mounting through hole. A baffle portion extending outward is arranged on the rear side of the sensor. After the sensor is nested in the mounting through hole of the water outlet seat, the baffle portion contacts the surrounding side of the mounting through hole on the inner wall side of the water outlet seat and will not fall out. Then, a rubber pad is inserted between the rear end of the sensor and the frame-shaped slot to achieve the sensor being nested and installed on the outer wall of the tubular water outlet seat without sinking inward and falling off, thereby achieving the sensor being reliably nested and installed on the outer wall of the tubular water outlet seat. Although this technical means is more flexible and selectable in terms of the installation position of the sensor compared to technical means A; however, the water outlet seat is usually made of metal, and it is difficult to form a frame-shaped slot on its inner wall; and since the inner cavity space of the water outlet seat is very limited, the existence of the frame-shaped slot further compresses the inner cavity space, so that the installation space of other components in the water outlet seat is limited, and the installation and structural design face greater challenges; at the same time, since the sensor needs to be stable, reliable and fixed, the rubber gasket is extruded and assembled, which is difficult to assemble.

[0005] C, based on technical means B, is improved by using a sleeve to replace the frame-shaped slot on the inner wall of the water outlet seat, such as the solution disclosed in CN105864492B. Its rubber ring (73) also needs to be squeezed and assembled between the sensing module (72) and the module window (611) of the sleeve (61). It also has the defect of high difficulty in assembly.

[0006] D, see Figure 3 and Figure 4 As shown, a circular mounting through hole 61' is provided on the tubular water outlet seat 6, and "L"-shaped slots 63 are respectively provided on both sides of the inner wall of the water outlet seat 6 corresponding to the mounting through hole 61', and the two wings of the circular sensor are respectively provided with outwardly extending fixing parts 25, and the fixing parts 25 of the two wings of the sensor are firstly placed in a vertical state, and then inserted into the circular mounting through hole 61', and then the sensor 2' is rotated so that the fixing parts 25 of the two wings are clamped into the "L"-shaped slots 63 on both sides of the inner wall of the water outlet seat 6 corresponding to the mounting through hole 61', and the fixing parts 25 of the two wings of the sensor are in a horizontal state, so that the fixing parts 25 of the two wings of the sensor cooperate with the "L"-shaped slots 63 on both sides of the mounting through hole 61', so that the sensor 2' can be reliably nested and installed on the outer wall of the tubular water outlet seat 6. Although this technical means has the advantages of simple structure and convenient assembly compared with the above-mentioned technical means, it is only applicable to the installation occasions of circular sensors.

[0007] Therefore, in view of the many defects existing in the prior art, a more compatible, universal and easy-to-assemble sensor installation component is needed to meet the production needs of faucets with sensors. Summary of the invention

[0008] In view of this, the present invention proposes an improved sensor installation technology to meet the above requirements.

[0052] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0053] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0054] Embodiment 1:

[0055] See also Figures 5 to 9 As shown, a sensor installation assembly is shown, which mainly includes: a fixing seat 1, a sensor 2, a fixing pin 3, and additionally a gasket 4 for providing buffer protection for the sensor 2. Figures 5 to 9 middle( Figures 10 to 14 The display direction of the sensor installation assembly shown in the drawings is the same as that of the other embodiments. During the installation operation, the installation opening of the water outlet seat 6 is usually placed upward to facilitate the installation of the sensor installation assembly. After the sensor installation assembly is installed in the tubular water outlet seat 6, the direction of the sensor installation assembly when the faucet is in use is opposite to the direction shown in the drawing.

[0056] The shape of the fixing seat 1 is adapted to the inner cavity shape of the installed water outlet seat 6. The fixing seat 1 in this embodiment is installed in the tubular water outlet seat 6, so its shape has an arc surface that can adapt to the cylindrical inner cavity, so that it looks roughly cylindrical. In addition, the center of the fixing seat 1 is a hollow inner cavity 11, so that there is an operating space when installing the sensor 2, and it also provides the pipes and other accessories of the faucet to pass through it; in addition, the cylindrical sleeve-shaped fixing seat 1 has a notch 12, so that the sensor 2 can be installed at the position of this notch 12, so that the main body shape of the fixing seat 1 of this embodiment is a hollow cylindrical sleeve with a notch 12. The fixing seat 1 with the sensor 2 installed in the notch 12 basically looks like a relatively complete cylindrical sleeve. If conditions permit, as shown in this embodiment, the two ends of the notch 12 can also be connected by a connecting strip 5 at the notch 12 to strengthen the strength of the fixing seat 1, and at the same time, the appearance is smoother, so as to facilitate the insertion into the inner cavity of the water outlet seat 6. The notch 12 of the fixing seat 1 is provided with installation guide grooves 13 for guiding the sensor 2 for installation. The arrangement direction of the installation guide grooves 13 is consistent with the installation direction of the sensor 2, and is basically arranged along the radial direction R of the fixing seat 1. At the same time, slots 14 for the fixing pins 3 to be inserted and matched are provided on both sides of the notch 12. The slots 14 of this embodiment are basically arranged along the axial direction A of the fixing seat 1, and are perpendicular to and intersecting the installation guide grooves 13. In other embodiments, the arrangement form of the slots can be adjusted as needed, as long as the fixing pins can be inserted, and the inserted fixing pins can limit the sensor that slides into the installation guide groove of the fixing seat; for example, the slots are horizontally arranged strip-shaped jacks, the jacks are initially located on the two outer sides of the notch of the fixing seat, and extend toward the installation guide groove until they end; for another example, the arrangement direction of the slots has an angle with the axial direction A of the fixing seat 1, so as to achieve oblique insertion for fixing. At the same time, in this embodiment, in order to guide the fixing pin 3 when it is inserted, the opening of the slot 14 is also provided with a flared guide structure 141 .

[0057] In addition, in order to prevent the fixing seat 1 from slipping circumferentially when installed on the water outlet seat 6, a positioning slot 15 can be provided on the fixing seat 1 to cooperate with the positioning block 64 in the inner cavity of the water outlet seat 6 for positioning; of course, other positioning technologies to prevent circumferential sliding can also be used to achieve positioning, so that the fixing seat has a corresponding different form of expression.

[0058] The sensor 2 includes a sensor protrusion 21 and a mounting abutment surface 22 that is wider than the sensor protrusion 21. The sensor protrusion 21 can be inserted into the mounting through hole 61 of the water outlet seat 6 and serve as a sensing collection window. After installation, the mounting abutment surface 22 that is wider than the sensor protrusion 21 abuts against the inner cavity surface around the corresponding mounting through hole 61 of the water outlet seat 6 to prevent the sensor 2 from slipping out; its shape is adapted to the inner cavity shape of the water outlet seat 6. The gasket 4 additionally provided in this embodiment can be sleeved on the sensor protrusion 21 of the sensor 2 to provide buffer protection to prevent the sharp burrs or edges of the mounting through hole 61 of the water outlet seat 6 from damaging the sensor 2. In addition, both sides of the sensor 2 include mounting protrusions 23 for matching and installing with the mounting guide grooves 13 on both sides of the notch 12 of the fixing seat 1. The height H of the mounting protrusion 23 satisfies the width W of the mounting guide groove 13, that is, the height H of the mounting protrusion 23 ≤ the width W of the mounting guide groove 13, so that the sensor 2 can slide smoothly into the mounting guide groove 13. The dimension of the mounting protrusion 23 in the sliding direction is defined as the width. In this implementation, the width of the mounting protrusion 23 is smaller than the length of the mounting guide groove 13, so that when the sensor 2 slides into the mounting guide groove 13 of the fixing seat 1 through the mounting protrusion 23 and is assembled in place, the mounting protrusion 23 will not block the fixing pin 3, so that the fixing pin 3 can be smoothly inserted into place from the slot 14 of the fixing seat 1 (usually against the surface of the mounting guide groove at the lower end), so that the inserted fixing pin 3 can be against the rear end of the sensor 2 on the width of the mounting protrusion 23 to prevent the sensor 2 from slipping out inward. Of course, in other embodiments, different mounting protrusion structures may also be used. For example, the mounting protrusion is configured to have a width equal to the length of the mounting guide groove, but the mounting protrusion is provided with a pin hole at a position corresponding to the slot in the width direction, so that a fixing pin can be inserted into the pin hole for pinning, thereby directly limiting the bidirectional sliding of the sensor on the mounting guide groove. However, this embodiment has obviously higher assembly requirements than the mounting protrusion 23 structural design adopted in this embodiment. At the same time, when this embodiment is adopted, the sensor 2 does not need to additionally set a mounting contact surface 22 that is wider than the sensor protrusion 21.

[0059] The sensor protrusion 21 in this embodiment is a roughly rectangular outline. The mounting protrusions 23 on both sides of the sensor 2 are implemented by using two spaced-apart flat plates, which is more convenient than using one mounting protrusion 23′ (see Fig.15Of course, a whole solid mounting protrusion with the same outer spacing but higher (thicker) can also be used to achieve the same stable positioning effect, but the two-piece flat plate structure with a spacing setting in this embodiment can also save the materials required for manufacturing.

[0060] The fixing pin 3 includes at least two pins 31 adapted to fit into the slots 14 on both sides of the notch 12 of the fixing seat, and the fixing pin 3 of this embodiment also includes an intermediate connecting portion 32 connecting the two pins 31, so that the fixing pin 3 of this embodiment is a one-piece structure roughly in the shape of "n". The fixing pin 3 with this structure can be directly formed by stamping from a thin metal rod, which is easy to manufacture. It should be supplemented that the intermediate connecting portion 32 connecting the two pins of the fixing pin 3 presents an outwardly protruding shape, so that after the fixing pin 3 is inserted into the slot 14 of the fixing seat 1, the connecting portion 32 will not block the hollow inner cavity 11 in the center of the fixing seat 1 due to the protruding design.

[0061] See also Fig.15 As shown, the installation process of this embodiment is: insert the fixing seat 1 into the inner cavity of the installed water outlet seat 6, ensure that the notch 12 of the fixing seat 1 faces the installation through hole 61 in the water outlet seat 6 for nesting and installing the sensor 2, and then extend the sensor 2 from the hollow cavity 11 of the fixing seat 1, and slide the installation protrusion 23 of the sensor 2 into the installation guide grooves 13 on both sides of the notch 12 until it slides into place (the sensor protrusion is inserted into the installation through hole of the water outlet seat); finally, insert the fixing pin 3 into the slots 14 on both sides of the notch 12 of the fixing seat, and the assembly operation of this embodiment and the water outlet seat 6 is completed. It can be seen that this embodiment has the advantage of simple and convenient assembly operation compared with the prior art.

[0062] Embodiment 2:

[0063] See also Fig.10 and Fig.11 As shown, the structure of the embodiment 2 is basically the same as that of the embodiment 1, except that the sensor 2' of the embodiment adopts a sensor protrusion 21' with a circular profile, and the corresponding gasket 4' is also circular. The embodiment can be used to be installed on the water outlet seat 6 of the circular installation through hole.

[0064] Embodiment 3:

[0065] See also Fig.12As shown, the structure of the embodiment 3 is basically the same as that of the embodiment 2, except that the fixing seat 1' of the embodiment adopts a front round and rear square shape to replace the cylindrical fixing seat 1 of the embodiment, and the fixing seat 1' is no longer provided with a positioning bayonet 15. Because the fixing seat 1' of the embodiment is installed on the water outlet seat with a corresponding inner cavity shape, the shape can already avoid circumferential slippage, so there is no need to provide a positioning bayonet 15 on the fixing seat 1'.

[0066] Embodiment 4:

[0067] See also Fig.13 and Fig.14 As shown, the structure of the embodiment 4 is basically the same as that of the embodiment 1, except that the embodiment 4 uses two "T"-shaped pins 31' as the fixing pins 3' to replace the "n"-shaped fixing pins 3 of the embodiment 1. Compared with the embodiment 1, the assembly operation of the embodiment 4 is slightly more complicated, but the cost of the fixing pins 3' is lower.

[0068] From the above examples 1 to 4, it can be seen that the sensor installation components of the above examples have the advantages of simple and convenient assembly operation compared to the prior art. In addition, the sensor installation component of the present invention is obviously compatible with the assembly of various forms of water outlet seats, suitable for different forms of water outlet seat cavities, suitable for different forms of sensor installation holes of water outlet seats, and suitable for installation at different positions of the water outlet seat. Therefore, the sensor installation component of the present invention is more compatible and universal.

[0069] Embodiment 5:

[0070] See also Figures 15 to 17 As shown, this embodiment shows an induction faucet, which includes a water outlet seat 6, a bent pipe member 7, a water outlet end member 8 (water outlet bubbler), a valve core assembly (not shown in the figure) and a sensor 2; wherein, the valve core assembly is installed in the valve core mounting hole of the water outlet seat 6, the first end of the water outlet seat 6 is connected to the bent pipe member 7, the end of the bent pipe member 7 is connected to the water outlet end member 8, and a rectangular mounting through hole 61 for nesting the sensor 2 is opened on the water outlet seat 6; the second end of the water outlet seat 6 is nested and mounted in the rectangular sensor 2 in the mounting through hole 61 of the water outlet seat 6 through the sensor mounting assembly of this embodiment 1.

[0071] Embodiment 6:

[0072] This embodiment illustrates the sensor installation method of the above-mentioned embodiment 5, specifically including:

[0073] First, it is best to place and fix the second end of the water outlet seat 6 upward to facilitate subsequent installation operations, but this step is not a necessary step.

[0074] Secondly, the fixing seat 1 is inserted into the inner cavity of the water outlet seat 6 until the positioning bayonet 15 of the fixing seat 1 cooperates with the positioning block 64 of the inner cavity of the water outlet seat 6 to be positioned in place, at which time the notch 12 of the fixing seat 1 corresponds to the mounting through hole 61 of the water outlet seat 6, and the insertion openings of the slots 14 on both sides of the notch 12 face upwards;

[0075] Then, depending on whether the gasket 4 is installed or not, if installed, after the gasket 4 is put on the sensor protrusion 21 of the sensor 2, the sensor 2 is inserted from the hollow cavity 11 of the fixing base 1, and the sensor 2 is transversely introduced and installed in the installation guide grooves 13 on both sides of the notch 12 of the fixing base 1;

[0076] Finally, the two pins 31 of the “n”-shaped fixing pin 3 are inserted into the slots 14 on both sides of the fixing seat notch 12 , and the installation of the sensor 2 and the water outlet seat 6 is completed.

[0077] It should be noted that reinforcement can be carried out after installation according to actual needs, such as gluing, glue pouring reinforcement, etc., which will not be explained in detail here.

[0078] 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.
