Description

Technical Field

[0001] The present invention relates to the technical field of sanitary equipment, and particularly to an illumination device installed on a toilet lid. Background Art

[0002] In the prior art, the existence and use of integrated toilet illumination devices are already well-known. To illuminate the interior of a toilet, toilet illumination devices with various structures have been designed and applied previously. Examples of relevant technical literature are as follows:

[0003] U.S. Patent US5513397 describes a toilet illumination device. Chinese Patent CN104545658 describes a light-emitting device installed in a toilet lid assembly. U.S. Patent US5664867 describes a toilet illumination device that operates when the lid is opened. U.S. Patent US5437066 describes a toilet illumination device triggered by a user's seating.

[0061] Through the modular design and the sanitary protection structure, the present invention solves the problems of inconvenient charging and sanitary risks in the prior art, and has both practicality and innovation.

[0062] [Lighting Module 10]

[0063] The lighting module 10 is a device that implements all the functions of the present invention. The lighting module 10 at least includes: a lighting module housing 11, a display component 12, a display printed circuit board assembly 14, a battery 15, a main printed circuit board assembly 16, a first light guide 17, and a reflector 18. The basic working principle of the lighting module 10 is: detecting the presence state of the user through a sensor and activating the lighting function when the user is detected.

[0064] On both sides of the cover 1, for detecting the presence of the user and implementing the lighting function, the preferred configuration of the lighting module 10 is as follows:

[0065] - Using the battery 15 as the power source;

[0066] - A main printed circuit board assembly (Main PCBA) 16 powered by the battery;

[0067] - A display printed circuit board assembly (Display PCBA) 14 directly connected to the main printed circuit board assembly 16 through a cable or connector. Both the main printed circuit board assembly 16 and the display printed circuit board assembly 14 are electronic circuit boards.

[0068] The main printed circuit board assembly 16 includes the following components:

[0069] - A second sensor 16.1 for detecting the presence of the user;

[0070] - At least one LED lamp 16.2 for lighting. According to the preferred embodiment of the present invention, multiple LED lamps are arranged in a circular layout on the circuit board;

[0071] - An interface 16.3 for connecting an external battery charger to implement the battery charging function.

[0072] The main printed circuit board assembly 16 is also responsible for managing the functions of the display printed circuit board assembly 14, and all necessary electronic control circuits are integrated on the main printed circuit board assembly 16.

[0073] The display printed circuit board assembly 14 includes the following components:

[0074] - A first sensor 14.1 for detecting the presence of the user;

[0075] - At least one LED lamp 14.2 for lighting. According to the preferred embodiment of the present invention, multiple LED lamps are installed on the circuit board.

[0076] Define the side of the cover 1 facing the toilet seat as the inner side, and the side opposite to it as the outer side; the first sensor 14.1 and the second sensor 16.1 face the outer side and the inner side of the cover 1 respectively.

[0077] On the outer side of the cover body 1, there is a display component 12, which is combined with the lighting module housing 11. The lighting module housing 11 has a specific shape so as to be combined with the module socket 20 in a fixed position. In a preferred embodiment of the present invention, the lighting module housing 11 is designed to have an oblong first flange 11.2, and a hollow first extension part 11.1 extends from the rear of the flange. The first extension part 11.1 is approximately cylindrical. The lighting module housing 11 is preferably made of thermoplastic materials such as ABS or ASA. In an alternative embodiment, the first flange 11.2 and the first extension part 11.1 can be designed into geometric shapes such as rectangles, squares, circles, ellipses or polygons.

[0078] According to Figure 19 and Figure 20 Schematic cross-sectional view of:

[0079] The display printed circuit board assembly 14, the battery 15 and the main printed circuit board assembly 16 are fixedly installed inside the lighting module housing 11. The LED lamp 14.2 on the display printed circuit board assembly 14 is combined with the display component 12 through a special structure to achieve light diffusion. The first sensor 14.1 extends outward from the reserved pore of the display component 12. The main printed circuit board assembly 16 is provided with a first light guide 17 and a reflector 18. The LED lamp 16.2 of the main printed circuit board assembly 16 cooperates with the first light guide 17 to achieve light distribution. The second sensor 16.1 and the interface 16.3 both extend through the first light guide 17 and the reflector 18 to the outside. All components of the lighting module 10 are fixedly combined by ultrasonic plastic welding or bonding process according to the preferred embodiment.

[0080] When the first sensor 14.1 detects the presence of a user, the LED lamp 14.2 is activated, and the light diffuses inside the display component 12, making it visible from the outside. The display component 12 is preferably made of transparent thermoplastic materials (such as polycarbonate PC, polymethyl methacrylate PMMA, acrylonitrile-butadiene-styrene copolymer ABS, styrene-acrylonitrile copolymer SAN). In order to achieve uniform light diffusion inside the display component 12 and weaken the visual effect of the strong light source of the lighting LED lamp 14.2 (such as softening or hiding), the material needs to be made into a matte structure through raw material additives. Patterns, symbols or logos can be set on the outer surface of the display component 12 according to needs, and these decorations can be achieved through spraying or in-mold insert injection (IML) technology.

[0081] When the second sensor 16.1 detects the presence of a user, the LED lamp 16.2 is activated, and the light is reflected inside the first light guide 17 and is strongly guided to the light irradiation surface 17.1 via the "R" vector path. See Figure 20。The first light guide member 17 is installed between the main printed circuit board assembly 16 and the reflector 18. The loss of reflected light in the first light guide member 17 can be significantly reduced by the reflector 18 and the reflection effect can be enhanced. The first light guide member 17 is preferably made of a transparent thermoplastic material (such as PC, PMMA, ABS, SAN). In order to achieve uniform light diffusion inside the first light guide member 17 and weaken the visual effect of the strong light source of the LED lamp 16.2, the material needs to be made to present a matte structure through raw material additives. The reflector 18 is preferably made of a material with a pure white, light-impermeable and highly reflective surface.

[0082] The lighting module 10 and the module socket 20 are magnetically coupled for easy quick installation and disassembly. The first magnet 13 is embedded at the bottom of the first flange 11.2 of the housing.

[0083] The software of the lighting module 10 controls the lighting mode based on the input data of the first sensor 14.1 and the second sensor 16.1. According to a preferred embodiment of the present invention, when the first sensor 14.1 on the display member 12 side detects the presence of a user, the lighting of the display member 12 and the first light guide member 17 will be activated simultaneously. In another preferred embodiment, when the device cover 1 is in the open state and the second sensor 16.1 detects the presence of a user, only the lighting of the first light guide member 17 is activated. In other possible embodiments of the present invention, the lighting scenario can be flexibly adjusted according to the sensor data. All functions and alternative strategies are controlled by the software on the main printed circuit board assembly 16.

[0084] [Module socket 20]

[0085] As shown in the attached Figure 3 、 11 and FIG. 12, the module socket 20 consists of a set of components fixed to the cover 1 of the toilet seat assembly. The module socket 20 at least includes an outer cover housing 21, a fixed flange 22, a second light guide member 24 and a base housing 25. The main purpose of the module socket 20 is as described above: to hold the lighting module 10 in the engaged position through a magnetic coupling relationship, and after the light generated by the first light guide member 17 is adjusted by the extension lens 24.2 part of the second light guide member 24, it is output outward from the lens window 25.2 on the base housing 25.

[0086] The outer cover housing 21 component is installed in the pre-reserved adaptation space on the cover 1. According to a preferred embodiment of the present invention, the outer cover housing 21 has a second flange 21.1 with an oblong geometric structure, as Figure 10As shown in the figure. A second extension 21.2 with a preferably cylindrical outer surface and a hollow interior is provided at the rear side of the second flange 21.1. At least one (preferably two) studs 21.3 for threaded connection are also arranged at the rear side of the second flange 21.1. According to a preferred embodiment, circular holes are provided on the cover body 1 for the second extension 21.2 and the studs 21.3 to pass through with a certain tolerance fit. In an alternative, holes with special shapes can also be formed by CNC machining. A stepped groove 21.4 geometrically matching the lighting module 10 is provided at the front side of the outer cover housing 21 for accommodating the lighting module 10. A second magnet 26 is embedded at the rear side of the second flange 21.1 for establishing a magnetic connection with the lighting module 10.

[0087] The fixed flange 22 is connected to the outer cover housing 21 by screws 23. The screws 23 pass through the screw holes 22.2 and are screwed into the studs 21.3 of the outer cover housing 21, thereby fixing the outer cover housing 21 on the cover body 1. The second extension 21.2 of the outer cover housing 21 passes through the inner cavity 22.1 of the fixed flange 22, so that assembly tolerance adjustment can be obtained for cover bodies 1 with different thicknesses. According to a preferred embodiment, the fixed flange 22 and the outer cover housing 21 are structurally matched and also adopt an oblong geometric design. In an alternative, the fixed flange 22 can be designed with geometric shapes such as rectangular, square, circular, oval or polygonal, and is preferably made of thermoplastic materials such as ABS and / or ASA.

[0088] The base housing 25 has a dual function: firstly, in combination with the second light guide 24, the light generated by the light-emitting surface 17.1 of the lighting module 10 is adjusted and output outward through the housing lens window 25.2, as Figure 10 ; secondly, in a preferred embodiment, 4 lens windows 25.2 are provided circumferentially on the base housing 25, and when the cover body 1 is in the open state, lighting in four directions of up, down, left and right can be achieved. The second light guide 24 receives light through its internal space 24.1 and diffuses the light to four sides by using the extension lenses 24.2. Correspondingly, 1 extension lens 24.2 is provided in each of the four directions of up, down, left and right of the second light guide 24, and the end of the extension lens 24.2 is embedded in the vacant position of the housing lens window 25.2 by snap connection. The combination of the base housing 25 and the second light guide 24 is fixed to the fixed flange 22 component that has been pre-installed on the cover body 1 by snap connection.

[0089] According to a preferred embodiment of the present invention, the base housing 25 is designed to be coordinated with other components of the module socket 20 in geometric structure and adopts an oblong shape. In an alternative embodiment of the present invention, the base housing 25 can be constructed in various geometric shapes such as rectangular, square, circular, oval, polygonal, etc.

[0090] The base housing 25 is preferably made of thermoplastic materials such as ABS and / or ASA. The second light guide member 24 is preferably made of transparent thermoplastic materials such as PC, PMMA, ABS, and SAN. In order to achieve the effect of light diffusion and softening inside the second light guide member 24, it is preferred to add raw material additives to form a matte structure.

[0091] As Figure 12 shown, when the module socket 20 is installed on the cover body 1, according to a preferred embodiment of the present invention, the module socket 20 has an approximately circular module socket inner cavity 20.1 inside. The lighting module 10 is assembled into the module socket inner cavity 20.1 with specific dimensional tolerances.

[0092] Figure 13 and Figure 14 shows the combination of the lighting module 10 and the module socket 20, where the lighting module 10 is shown in a non-sectioned manner and the module socket 20 is shown in a sectioned manner.

[0093] Figure 15 and Figure 16 Illustrates the relationship between the components through a full cross-sectional view and visually presents the process of the light generated by the LED lamp 16.2 being transmitted through the "R" vector.

[0094] When the lighting module 10 is inserted into the module socket 20, the lighting module magnet 13 and the module socket magnet 26 form a magnetic connection relationship. Thus, when opening and closing the cover body 1, the lighting module 10 can be prevented from falling off by itself. At the same time, when it is necessary to remove the lighting module 10 to replace the battery, the separation of the magnetic coupling is extremely simple and labor-saving for the user.

[0095] The second sensor 16.1 of the lighting module 10 extends outward from the sensor window 25.1 on the base housing 25 of the module socket 20, as Figure 10 shown.

[0096] According to a preferred embodiment of the present invention, the first sensor 14.1 and the second sensor 16.1 of the lighting module 10 are passive infrared sensors (PIR) based on motion detection technology. In possible alternative embodiments of the present invention, sensors using technologies such as time-of-flight (ToF), ultrasonic, infrared (IR), and microwave (radar) can be used.

[0097] Another important function of the module socket 20 is that when the cover body 1 is in the closed state, during the period of delivering flushing water to the toilet, it can provide a protective barrier for the lighting module 10 to ensure that the device remains clean.

[0098] Although the present invention has been specifically shown and described in connection with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined by the appended claims, and all such changes are within the scope of protection of the present invention.
