Description

Technical Field

[0001] The utility model relates to the technical field of timer switches, in particular to a timer switch with an integrated light guide mechanism. Background Art

[0002] With the advancement of electronic technology, time switches are widely used in various household appliances and industrial equipment to control the on and off of circuits. Traditional time switches often require manual setting and implement the timing function through mechanical structures or simple electronic timers. To facilitate user understanding of the operating status of the time switch, many time switches are equipped with indicator lights to display information such as power status and operating mode.

[0003] However, existing timer switches have several design deficiencies. For one thing, in some timer switch designs, the indicator light source (such as an LED) is often mounted directly on the panel or uses an additional light guide component to direct light from the inside to the external indicator position. This design can complicate the product assembly process and increase manufacturing costs. Furthermore, when the indicator light source is far from the external indicator point, ensuring sufficient brightness often requires a higher-power light source or a complex optical path design. This not only affects the product's energy efficiency but can also reduce reliability due to the excessive number of components.

[0004] In addition, the lamp beads in traditional designs are usually processed separately and then assembled into the lamp holes of the shell. The lamp beads and the circuit board are also connected by wire welding. Such a design is not only complex in process and structure, but also difficult to assemble and costly.

[0005] Therefore, in order to address the problems existing in the above-mentioned prior art, the present application provides a timing switch with a more compact structure, lower manufacturing cost and the ability to effectively improve the stability of light source indication. Utility Model Content

[0006] In view of the deficiencies in the background technology, the utility model provides a timing switch with an integrated light guide mechanism.

[0007] The technical solution adopted by the utility model is: a timing switch with an integrated light-guiding mechanism, comprising a bottom shell, a circuit board arranged on the bottom shell, a cover body covering the bottom shell, and a timing setting dial arranged on the cover body, the circuit board is provided with a light-emitting device, the cover body is provided with an indicator light hole, and a light-guiding column is integrally formed on the bottom shell on one side of the light-emitting device, and the light-guiding column extends away from one end of the bottom shell to the indicator light hole.

[0008] Furthermore, the light guide column includes a main body portion connected to the bottom shell and a lamp ball on the top of the main body portion, and the lamp ball extends into the above-mentioned indicator hole.

[0009] Furthermore, the main body is an "L"-shaped structure.

[0010] Furthermore, a notch is provided on one side where the main body portion is connected to the bottom shell.

[0011] Furthermore, a refraction groove is provided in the bottom shell directly below the light emitting device, and a focusing convex surface is provided in the refraction groove.

[0012] Furthermore, the light emitting device is a light emitting diode or an LED lamp.

[0013] The beneficial effects of the utility model are:

[0014] 1. Simplified assembly process: The integrated light guide column design reduces the use of additional light guide components and complex optical path design, making the assembly process of the entire product simpler and faster, reducing production difficulty.

[0015] 2. Reduced costs: The integrated design eliminates the need for separate processing of light guide components and subsequent assembly steps, effectively controlling manufacturing costs. Furthermore, because a high-power light source is no longer required to ensure brightness over long distances, material costs are further reduced.

[0016] 3. Improved reliability: By eliminating the need for wires to connect the lamp beads to the circuit board in traditional designs, potential welding failure points are eliminated and the stability of the overall structure is enhanced. At the same time, the one-piece light guide column also ensures better sealing performance, preventing dust or moisture from entering and affecting the operation of internal components, thereby extending the product life.

[0017] 4. Optimized energy efficiency ratio: Thanks to a more efficient light transmission mechanism, it provides a more stable and reliable light source indication effect, and can achieve good visual indication effects even under low power conditions, which helps to reduce energy consumption and conform to the concept of green environmental protection.

[0018] In addition to the above-described purposes, features and advantages, the present invention has other purposes, features and advantages. The present invention will be further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] The utility model provides a timing switch with an integrated light guide mechanism.

[0026] In this embodiment, referring to Figure 1-3 The timing switch with an integrated light-guiding mechanism includes a bottom shell 1, a circuit board 2 arranged on the bottom shell 1, a cover body 3 covering the bottom shell, and a timing setting dial 4 arranged on the cover body. The circuit board is provided with a light-emitting device 5, the cover body is provided with an indicator light hole 6, and a light guide column 7 is integrally formed on the bottom shell on one side of the light-emitting device. The light guide column extends away from one end of the bottom shell to the indicator light hole.

[0027] In this technical solution, the internal structure of the timer switch is simplified by placing the light-emitting device directly on the circuit board and using an integrally formed light guide on the bottom shell to direct light to the indicator light hole. The integrally formed light guide effectively reduces the number of parts and assembly steps, improving assembly efficiency and reducing production costs.

[0028] The light source design that is directly transmitted from the circuit board to the indicator light hole ensures the consistency and stability of the light source indication and improves the reliability of the product.

[0029] Specifically, the light guide column includes a main body portion 8 connected to the bottom shell and a lamp ball 9 on the top of the main body portion, and the lamp ball extends into the above-mentioned indicator hole.

[0030] The light bulb at the top of the light guide effectively concentrates and diffuses light, making the indicator light brighter and more even. The bulb extends into the indicator light hole, further optimizing the light propagation path, reducing light loss and enhancing visual recognition.

[0031] Specifically, the main body is an "L"-shaped structure.

[0032] The main part of the "L"-shaped structure can adapt to the spatial layout between the bottom shell and the cover body of different shapes, increasing the flexibility of the design.

[0033] Specifically, a notch 10 is provided on one side where the main body is connected to the bottom shell; a refraction groove 11 is provided in the bottom shell directly below the light-emitting device, and a focusing convex surface 12 is provided in the refraction groove.

[0034] The bottom shell features a refraction groove and a built-in light-concentrating convex surface to help focus light from the light-emitting device, improving lighting efficiency. The light-concentrating convex surface enhances light concentration, making the indicator brighter while reducing energy loss.

[0035] Specifically, the light emitting device is a light emitting diode or an LED lamp.

[0036] Light emitting diodes or LED lights are the light emitting device of choice, with advantages such as small size, low power consumption and long life.

[0037] Technical personnel please note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
