Description

Annular lamp assembly and intelligent toilet

Technical Field

The utility model relates to the technical field of intelligent toilet manufacturing. More particularly, the present utility model relates to an annular light assembly, and to a smart toilet including such an annular light assembly.

Background

The toilet bowl is one of the indispensable bathroom accessories in the modern society. With the development of toilet manufacturing industry, the demands of people on the integration level and the functionality of the toilet are also higher and higher, so that the use of the toilet is more and more intelligent.

The existing intelligent toilet can be simultaneously provided with an annular light source and a coke sensor. The lighting of the ring light source may indicate, for example, an energized state of the intelligent toilet, or a color change of the ring light source may indicate an abnormal state of the intelligent toilet. The pyroelectric sensor is also called a "pyroelectric type infrared sensor", and the sensor can detect the amount of change in infrared rays when a person (object) having a temperature difference from the environment moves, and is particularly suitable for sensing a human body because the temperature difference can be detected. When a user approaches the intelligent toilet, the head of the user can be sensed in the sensing range by the coke sensor, and a signal is sent to the main board of the intelligent toilet so as to control the automatic opening of the toilet cover.

In the prior art, the light emitting area is generally defined to a specific area by mounting a "face mask" for covering the annular light source. However, in some cases, the annular light source and the pyroelectric sensor cannot be separately disposed due to space limitations of the product and arrangement positions and/or angles of the pyroelectric sensor. However, if the ring-shaped light source and the pyroelectric sensor are integrated in the same structure, the conventional "face mask" cannot be used because of the need to transmit human infrared rays, and light leakage and halation are easily caused.

Fig. 1 to 10 show a preferred embodiment of the ring-shaped lamp assembly of the present utility model, which mainly includes a cover plate 10, a sensing window 20, a light guide ring 30, and a ring-shaped lamp module 40.

As shown in fig. 1 and 2, the cover plate 10 includes an inner cover plate 12 and a top cover plate 11 fixed above the inner cover plate 12, for example, by snap-fit connection or the like, to form a top appearance surface of the product, wherein the top cover plate 11 and the inner cover plate 12 are provided with a top cover opening 111 and an inner cover opening 121, respectively, aligned with each other.

As shown in fig. 1 to 3, the sensing window 20 is made of, for example, high Density Polyethylene (HDPE) to be suitable for transmitting light and human infrared rays, and the sensing window 20 includes a middle portion 21 and an edge portion, wherein the middle portion 21 covers the top cover opening 111 and the inner cover opening 121 to form a product top appearance surface, and the edge portion integrally extends from an outer peripheral edge of the middle portion 21 to be fixed to the cover plate 10.

In this embodiment, the edge portion of the sensing window 20 includes an inclined portion 22 extending obliquely downward from the intermediate portion 21 and a fixing portion 23 extending from the outer peripheral edge of the inclined portion 22 in a manner substantially parallel to the intermediate portion 21 and fixed to the lid plate 10, wherein the fixing portion 23 is sandwiched between the inner lid plate 12 and the top lid plate 11 around the top lid opening 111 and the inner lid opening 121, and is adhered to the upper surface of the inner lid plate 12, for example, by double-sided adhesive tape.

The ring-shaped lamp module 40 is fixed to the cover plate 10 below the sensing window 20, and includes a ring-shaped light source 421 and a pyroelectric sensor 45 surrounded by the ring-shaped light source 421 so that light is transmitted outward by the ring-shaped light source 421 via the middle portion 21 of the sensing window 20, and human infrared rays are sensed by the pyroelectric sensor 45 also via the middle portion 21 of the sensing window 20.

The light guide ring 30 is disposed between the ring-shaped lamp module 40 and the middle portion 21 along the edge of the middle portion 21 of the sensing window 20 to be able to guide the light emitted from the ring-shaped light source 421 to the middle portion 21 and to be transmitted outward along the edge of the middle portion 21.

As shown in fig. 1 to 4, the material of the light guide ring 30 is, for example, polycarbonate (PC), and the light guide ring 30 and the inner cover plate 12 are preferably fixed to each other by two-shot molding. More specifically, the light guide ring 30 includes a light guide ring body 31 extending substantially perpendicular to the middle portion 21 of the sensing window 20 and a protrusion 32 integrally protruding from the light guide ring body 31 toward a flange 122 surrounding the inner cap opening 121 on the inner cap plate 12 to be engaged with the flange 122, wherein the light guide ring body 31 has a specific thickness to meet the width requirement of the annular light emitting band.

In manufacturing, the light guide ring 30 may be first injection molded, and then the inner cover plate 12 may be injection molded on the light guide ring 30 for two times, so that the protrusion 32 is tightly matched with the flange 122 of the inner cover plate 12, which not only can accurately position the light guide ring 30 to meet the requirement of the light emitting position, but also can effectively prevent the leakage of moisture from the position toward the lower annular lamp module 40.

Further, in this embodiment, the top of the light guide ring 30 includes a slope 33 that conforms to the sloped portion 22 of the sensing window 20. By the matching design of the inclined part 22 and the inclined surface 33, not only the light emitting area can be limited to the edge specific area of the middle part 21 of the sensing window 20, but also the defect that the outermost edge position of the middle part 21 is difficult to emit light due to the wall thickness can be overcome. Fig. 10 schematically shows an annular light-emitting region I extending along the edge of the intermediate portion 21 and meeting the width requirement.

As shown in fig. 1, 2 and 5 to 9, the annular lamp module 40 mainly includes a lamp housing 41, a circuit board 42, a light blocking ring 43, a support plate 44 and a thermoelectric sensor 45.

The lamp housing 41 includes a bottom plate 411 arranged substantially parallel to the top cover plate 11 and the inner cover plate 12, and an outer wall 412 extending substantially perpendicularly upward from an outer peripheral edge of the bottom plate 411, wherein the bottom plate 411 is provided with a mounting opening 419 for mounting the pyroelectric sensor 45, and is provided with a plurality of lamp housing mounting parts 414 (three lamp housing mounting parts 414 are included in the illustrated embodiment) with screw holes extending integrally downward, so that the lamp housing 41 can be fixed to the inner cover plate 12 by screws passing through these lamp housing mounting parts 414. In addition, the lamp housing 41 further includes a mounting wall 413 surrounding at least a portion of the opening 419 and protruding from both upper and lower sides of the bottom plate 411.

The circuit board 42 (not shown in fig. 1 and 2) is a Printed Circuit Board (PCB), which circuit board 42 is fixed to the upper side of the bottom plate 411 inside the outer wall 412 of the lamp housing 41, and is provided with a circuit board opening 422 surrounding the mounting wall 413.

The light-blocking ring 43 is fixed to the circuit board 42 and the upper side of the bottom plate 411 on the inner side of the outer wall 412 of the lamp housing 41, and defines an annular space E as an inner wall together with the outer wall 412, the lower circuit board 42 and the upper light-guiding ring 30. More specifically, the light blocking ring 43 includes a light blocking ring body 431 and a protrusion 432, wherein the light blocking ring body 431 forms an inner wall of the annular space E for blocking light, and the protrusion 432 integrally protrudes from the light blocking ring body 431 toward the outer wall 412 to support the light guiding ring 30 and can achieve a condensing effect.

In addition, the light blocking ring 43 further includes a plurality of light blocking ring mounting portions 433 (including two light blocking ring mounting portions 433 opposite to each other in the illustrated embodiment) integrally extended inward from the light blocking ring body 431, correspondingly, the circuit board 42 is provided with a plurality of screw holes 423 through which screws pass, and the bottom plate 411 is provided with a plurality of mounting posts 415 (including two screw holes 423 and two mounting posts 415 in the illustrated embodiment) integrally protruded upward into which screws pass to fix the light blocking ring 43, the circuit board 42, and the bottom plate 411 to each other from top to bottom by screws passing through the light blocking ring mounting portions 433 and the screw holes 423 and into the mounting posts 415.

Further, in this embodiment, the bottom plate 411 is provided with a plurality of positioning pins 416 integrally protruding upward, and the circuit board 42 is correspondingly provided with a plurality of positioning holes 424 (four positioning pins 416 and four positioning holes 424 are included in the illustrated embodiment) through which these positioning pins 416 pass, so that the circuit board 42 can be pre-positioned on the bottom plate 411 before mounting.

The annular light source 421 is disposed on the circuit board 42 in the annular space E, and includes, for example, a plurality of LED beads arranged in the annular space E at intervals. In this embodiment, the ring light source 421 includes a plurality of groups of LED beads arranged at uniform intervals in the annular space E, each group includes two LED beads, and scattering areas of light emitted from adjacent two groups have partial overlapping, so that the lamp light can be ensured to be annular as a whole, and uniformity of luminous intensity can be ensured.

Therefore, the light emitted by the LED beads together can form an annular luminous band at the edge of the middle portion 21 of the sensing window 20 after passing through the annular space E and being conducted by the light guide ring 30, and the defects of easy light leakage and light divergence caused by the open annular LED beads are overcome by the design of the light blocking ring 43 and the protruding portion 432 thereof.

The pyroelectric sensor 45 is fixed to the lamp housing 41 inside the annular space E through the mounting opening 419 and the circuit board opening 422 of the bottom plate 411. More specifically, the pyroelectric sensor 45 is supported on the support plate 44, and the support plate 44 is fixed to the lamp housing 41 by a snap connection.

As shown in fig. 6 to 9 in particular, in this embodiment, the mounting wall 413 of the lamp housing 41 is provided with a plurality of snap posts 417 and a plurality of snaps 418 (including two snaps 418 opposing each other in the illustrated embodiment) integrally protruding inward, wherein the snap posts 417 extend in a direction substantially perpendicular to the bottom plate 411 at different lengths inside the mounting wall 413 and are parallel to each other, and the snaps 418 are arranged below the snap posts 417 inside the mounting wall 413, so that the support plate 44 can be snapped between the snap posts 417 and the snaps 418, and so that the support plate 44 can be arranged at a specific angle with respect to the bottom plate 411.

It will be appreciated that the inclination angle α of the support plate 44 with respect to the bottom plate 411 may be set according to the needs of the actual application, for example, the inclination angle α may be set to 30 ° to 60 °, for example, equal to about 40 °.

Fig. 11 to 14 show a preferred embodiment of the mount 50 of the intelligent toilet of the present utility model, the mount 50 being mounted with the ring-shaped lamp assembly as shown in fig. 1 to 10. For clarity, fig. 13 is a perspective view of the top cover plate 11 removed, and fig. 14 is a perspective view of the top cover plate 11 and the sensing window 20 removed.

As shown in fig. 11 to 14, in this embodiment, the above-mentioned ring-shaped lamp assembly is fixed to the top of the mount 50, wherein the top cover plate 11 and the intermediate portion 21 of the sensing window 20 positioned at the substantially central position of the top cover plate 11 form an outer appearance surface of the top of the product, and the ring-shaped lamp module 40 is fixed to the inner cover plate 12 under the sensing window 20 such that light emitted by the ring-shaped light source 421 of the ring-shaped lamp module 40 forms a ring-shaped light emitting area I at the edge of the intermediate portion 21 of the sensing window 20, and such that the pyroelectric sensor 45 of the ring-shaped lamp module 40 senses human infrared rays via the intermediate portion 21 of the sensing window 20.

Fig. 15 is a schematic view of the sensing range of the pyroelectric sensor of the intelligent toilet. For example, as shown in fig. 1 and 15, since the inclination angle α of the support plate 44 supporting the thermoelectric sensor 45 with respect to the bottom plate 411 of the lamp housing 41 is set to about 40 ° for sensing a human body, and the sensing angle range β of the thermoelectric sensor 45 is also about 40 °, the thermoelectric sensor 45 can sense the head H of a user whose height H is about 1.6m to a distance d from the front end of the intelligent toilet bowl of about 200mm at an ambient temperature of, for example, about 20 ℃, thereby transmitting a signal to the main board of the intelligent toilet bowl to control automatic opening of the cover.

In the intelligent toilet, the above-mentioned inclination angle α and sensing angle range β can ensure that the ring light source 421 of the ring light module 40 does not affect the normal operation of the pyroelectric sensor 45, and the installation position of the pyroelectric sensor 45 does not affect the normal installation and operation of the ring light source 421.

Therefore, the integrated design of the annular light source 421 and the pyroelectric sensor 45 in the annular light module 40 overcomes the defect that the annular light source 421 and the pyroelectric sensor 45 cannot be separately arranged due to the limitation of the space of the product, the arrangement position and/or angle of the pyroelectric sensor 45, and the like, and not only can meet the requirements of the luminous effect and the human body induction, but also can ensure that the annular light source 421 and the pyroelectric sensor 45 do not interfere with each other in the installation position and the function.

While the foregoing has described the technical content and features of the present utility model, it will be appreciated that those skilled in the art, upon attaining the teachings of the present utility model, may make variations and improvements to the concepts disclosed herein, which fall within the scope of the present utility model.
