Description

Technical Field

[0001] This utility model relates to an automatic water tank cleaning device, a light display device for the automatic water tank cleaning device, and a light guide component for the light display device. Background Technology

[0002] For pool facilities such as swimming pools, automatic pool cleaning devices can be used for automatic or assisted cleaning. For example, automatic pool cleaning devices can be designed to operate their cleaning mechanisms while moving along the bottom, walls, and / or surface of the pool to filter pool water and absorb waste.

[0003] However, in the current automatic water tank cleaning device's lighting display device, in modules with a large number of LEDs and close proximity between them, transparent parts are often used to isolate the LEDs from the external environment in order to ensure the sealing of the cavity. However, such a structure often leads to light leakage between the LEDs, which cannot guarantee the effective display of the light, making it difficult for users to observe the corresponding machine's operating indication status.

[0004] Therefore, it is urgent to solve the problem of effective display of underwater multi-LED modules, especially to prevent light leakage between LEDs that are close to each other. Summary of the Invention

[0005] A light guide assembly for a light display device of an automatic water tank cleaning device is disclosed, comprising: a plurality of light guide columns; and at least one light shield disposed between the plurality of light guide columns and covering the outer surfaces of the plurality of light guide columns, such that the light sources guided by each of the plurality of light guide columns do not interfere with each other.

[0006] In one or more embodiments, the plurality of light guide pillars are connected into one unit by ribs.

[0007] In one or more embodiments, the portion of the rib located between the first and second light guide pillars among the plurality of light guide pillars is configured as a turning structure.

[0008] In one or more embodiments, the at least one light shield wraps the outer surface of the plurality of light guide pillars by a die-cutting process.

[0009] In one or more embodiments, each light guide post is configured as a light guiding structure through a light-transmitting material.

[0010] In one or more embodiments, each light shield is configured as a light-shielding structure using an opaque material.

[0011] In one or more embodiments, the material used to form the light shield has a lower hardness than the material used to form the light guide column.

[0012] A light display device for an automatic pool cleaning system is also disclosed, comprising: a housing including a transparent upper shell; a light source disposed within the housing; and a light guide assembly as described above, disposed between the transparent upper shell and the light source.

[0013] In one or more embodiments, the light guide assembly is secured to the underside of the transparent upper shell inside the housing by snap-fit.

[0014] In one or more embodiments, the housing further includes a protective lower shell, which is connected to the transparent upper shell and forms a sealed space within the housing.

[0015] In one or more embodiments, the protective lower shell and the transparent upper shell are connected together by a sealing ring and screws.

[0020] Figure 4 An example of an automatic pool cleaning device according to an embodiment of the present disclosure is shown schematically. Detailed Implementation

[0021] Embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. In the drawings, identical or equivalent parts are given the same reference numerals, and their descriptions are not repeated.

[0022] An automatic sink cleaning device can be equipped with a lighting display to show information such as operation instructions, operation signals, and / or operation status during operation. For example, the lighting display can use a transparent cover to isolate the light source from the external environment, ensuring the sealing of the internal cavity of the automatic sink cleaning device while providing lighting display. However, if multiple light sources (e.g., a multi-LED structure) are used and the distance between the light sources is close, the transparent cover structure may cause interference between the different light sources, thus failing to ensure effective lighting display. For example, it may make it difficult for the user to clearly observe information such as operation instructions, operation signals, and / or operation status.

[0023] Figure 1 An exemplary light guide assembly 100 of an embodiment of this disclosure is schematically shown. (As...) Figure 1 As shown, the light guide assembly 100 may include a plurality of light guide pillars 110 and at least one light shield 120. The light shield 120 may be disposed between the plurality of light guide pillars 110 and cover the outer surfaces of the plurality of light guide pillars 110. With such a structure, the light sources guided by each of the plurality of light guide pillars 110 can be independent of each other, thereby facilitating the effective display of light.

[0024] The light guide post 110 can be a light-guiding structure configured with a light-transmitting material and can have any suitable shape. For example, the light guide post 110 can be formed from transparent materials such as ABS plastic, polycarbonate plastic, and polymethyl methacrylate plastic. In addition, materials such as pearlescent powder can be added to the material forming the light guide post 110 to increase the uniformity of light guiding.

[0025] The light shield 120 can be a light-shielding structure configured with an opaque material. For example, the light shield 120 can be formed of a dark (e.g., black) elastic material such as dark rubber or dark silicone. The light shield 120 can be wrapped (e.g., tightly wrapped) around the outer side of the light guide post 110 by any suitable method such as overmolding to prevent light from leaking out through the gaps between the light guide posts 110.

[0026] For example, the material hardness of the light shield 120 can be less than that of the light guide post 110. For example, the light guide post 110 can be a hard plastic light guide post, while the light shield 120 can be a soft plastic light shield. This allows the light shield 120 to more tightly wrap around the outer surface of the light guide post 110.

[0027] In addition, such as Figure 2 As shown, multiple light guide pillars 110 can be connected into a single unit via ribs 130, which facilitates easier demolding or forming of multiple light guide pillars 110 as a whole, and also increases the overall strength of the light guide pillars 110. The ribs 130 can be of any suitable thickness, for example, approximately 2 mm, 3 mm, etc. Additionally, as... Figure 2 As shown, the rib portion between two adjacent light guide pillars 110 can be configured as a turning structure, thereby effectively preventing light leakage between adjacent light guide pillars.

[0028] Figure 3 A portion of an exemplary light display device 300 according to an embodiment of the present disclosure is shown schematically.

[0029] like Figure 3As shown, the lighting display device 300 may include: a housing, including a transparent upper shell 310; a light source 320 disposed within the housing of the lighting display device 300; and a light guide assembly 300 disposed between the transparent upper shell 310 and the light source 320. For example, the light guide assembly 300 may be fixed to the underside of the transparent upper shell 310 inside the housing of the lighting display device 300 by means of a snap-fit ​​330 or any other suitable means.

[0030] For example, the light source 320 can be a PCB (printed circuit board) light board including multiple LED (light-emitting diode) beads, or any other suitable type of light source. At least a portion of the light emitted from the light source 320 can be guided by the multiple light guide pillars 110 of the light guide assembly 300 and emitted to the outside of the lighting display device 300 via the transparent upper shell 310. The light shield 120 disposed between the multiple light guide pillars 110 covers the outer surfaces of the multiple light guide pillars 110, so that the light sources guided by each light guide pillar 110 do not interfere with each other, thereby enabling the lighting display device 300 to effectively perform lighting display.

[0031] In addition, such as Figure 3 As shown, the housing of the light display device 300 may further include a protective lower housing 340. The protective lower housing 340 and the transparent upper housing 310 can be connected together to form a sealed space 350 within the housing of the light display device 300, thereby protecting internal components of the light display device 300, such as the light source 320, from corrosion. For example, the protective lower housing 340 and the transparent upper housing 310 can be connected together by a sealing ring 360 and / or any other suitable means such as screws.

[0032] The lighting display device 300 has a simple structure and is easy to assemble, which helps to reduce production and maintenance costs.

[0033] Figure 4 An exemplary automatic sink cleaning device 400 according to an embodiment of the present disclosure is schematically shown, which may include the aforementioned light display device 300. For example, the transparent upper shell 310 of the light display device 400 may be part of the outer casing of the automatic sink cleaning device 400. The structure of the light display device 300 ensures effective light display, allowing users to clearly observe information such as operation instructions, operation signals, and / or operation status of the automatic sink cleaning device 400.
