Description
Technical Field
[0001] This utility model relates to the field of switch technology, and in particular to a push switch and an electric kettle. Background Technology
[0002] Currently, some electric kettles typically have a push-button switch on the kettle body, which users can press or pull up to control the kettle's heating element. In existing technology, push-button switches usually include a switch bracket that can rotate up and down on the kettle body. To indicate the kettle's operating status, the pressing part is made of a translucent material, and a light-emitting element is installed inside to indicate the kettle's operating status. The light emitted by this element makes the entire pressing part illuminate. However, current push-button switches emit diffused light, resulting in uneven brightness, dim overall illumination, and poor indication. Furthermore, the visual effect of the light is also poor, failing to meet increasingly higher aesthetic demands. Utility Model Content

[0031] Reference Figures 1 to 3According to a first aspect of the present invention, a push switch includes a switch bracket 100, a light-blocking housing 200, and a light-transmitting light guide 300. The switch bracket 100 is provided with a mounting portion 110, and a mounting cavity 111 is provided inside the mounting portion 110. A light-emitting element 500 is installed inside the mounting cavity 111. A light-blocking housing 200 has a light-guiding channel 210 extending in a left-right direction at its left end and a reflective cavity 220 opening upwards at its right end. The light-guiding channel 210 communicates with the reflective cavity 220, and the mounting portion 110 is inserted into the light-guiding channel 210. The light guide 300 is disposed inside the reflective cavity 220. A cavity 310 is provided inside the cavity 310. The upper sidewall of the cavity 310 forms a light-emitting part 320, and the lower sidewall of the cavity 310 forms a light guide plate 330. The upper surface of the light guide plate 330 is provided with a wave-shaped first light guide structure 331. The first light guide structure 331 is opposite to the light guide channel 210, and all the peaks of the first light guide structure 331 are distributed in the left-right direction. The mounting part 110 is light-transmitting, and the light emitted by the light-emitting element 500 can enter the reflective cavity 220 from the light guide channel 210. The inner wall of the reflective cavity 220 can reflect the light to the light-emitting element 300, and the first light guide structure 331 can guide the light to the light-emitting part 320.
[0032] The push switch provided by this utility model allows light emitted from the light-emitting element 500 to enter the reflective cavity 220 through the light guide channel 210. Then, the light is reflected by the inner wall of the reflective cavity 220 to the light guide element 300, and the light in the left-right direction is guided to the light-emitting part 320 through the first light guide structure 331. Finally, the light emitted by the light-emitting element 500 can be concentrated and emitted from the light-emitting part 320, thereby making the push switch bright and concentrated, improving the indication effect of the push switch. Users can also see the wave shape of the first light guide structure 331 from the light-emitting part 320. Thus, the visual effect of the push switch light is better, meeting people's increasingly high aesthetic requirements.
[0033] Understandably, according to optical principles, when light rays in the left-right direction strike the left surface of a certain peak of the first light guide structure 331, part of the light rays are reflected toward the light output section 320, and the other part enters the peak and is refracted on the right surface of the peak toward the left surface of the next peak of the first light guide structure 331, and so on. Thus, the first light guide structure 331 can guide light rays in the left-right direction to the light output section 320, so that the light rays can be emitted from the light output section 320.
[0034] It should be noted that in some other embodiments, the right end of the mounting cavity 111 is open. In this case, the mounting part 110 may be opaque, and the light emitted by the light-emitting element 500 can enter the light guide channel 210 from the right end opening of the mounting cavity 111, and then enter the reflective cavity 220 along the light guide channel 210.
[0035] Reference Figure 1 , Figure 2 and Figure 5 It can be imagined that in some embodiments of this utility model, the angle between the left side surface of the first light guide structure 331 and the left and right directions is between 45 and 65 degrees. Therefore, the angle between the light reflected from the left side surface of the first light guide structure 331 and the left and right directions is between 50 and 90 degrees. The angle between the right side surface of the first light guide structure 331 and the left and right directions is between 75 and 90 degrees. This ensures that the light does not undergo total internal reflection at the right side surface of the first light guide structure 331, so that the light can be refracted on the right side surface of a certain wave of the first light guide structure 331 to the next wave or the light output part 320.
[0036] Reference Figure 1 , Figure 2 and Figure 5 As can be imagined, in some embodiments of this utility model, the lower surface of the light guide plate 330 is provided with a wave-shaped second light guide structure 332. All the peaks of the second light guide structure 332 are distributed in the left and right direction. Thus, the second light guide structure 332 and the lower inner wall of the reflective cavity 220 can cooperate with each other to guide more light to the first light guide structure 331, and then the first light guide structure 331 guides the light to the light output section 320. As a result, the brightness of the light output section 320 can be further improved.
[0037] It can be imagined that when light rays in the left-right direction pass through the first light guide structure 331, they will be deflected to the left, while the light rays guided by the second light guide structure 332 to the first light guide structure 331 will be deflected to the right, thereby forming a compensation and making the light output section 320 emit light more evenly.
[0038] like Figure 2 As shown, in some embodiments, the left and right surfaces of the peak of the second light guide structure 332 are symmetrically arranged, wherein the angle between the left surface of the peak of the second light guide structure 332 and the left and right directions is between 70 degrees and 80 degrees.
[0039] Reference Figure 2 and Figure 5 As can be imagined, in some embodiments of this utility model, the cavity 310 has a left side wall and a right side wall. The angle between the left side wall of the cavity 310 and the left and right directions is 85 degrees to 90 degrees. The left side wall of the cavity 310 is arranged opposite to the light guide channel 210. In this way, the light coming out of the light guide channel 210 is less reflected when it passes through the left side wall of the cavity 310, and the light can enter the light guide 300 more easily.
[0040] Reference Figure 5As can be imagined, in some embodiments of this utility model, the cavity 310 has a rear sidewall and the front side of the cavity 310 is open. With the above configuration, the light guide 300 can be easily integrally formed by the mold, reducing the production difficulty.
[0041] Of course, in some other embodiments, the cavity 310 also has a front sidewall. In this case, the rear side of the cavity 310 is open to facilitate the production of the light guide 300.
[0042] Reference Figures 2 to 4 As can be imagined, in some embodiments of this utility model, the push switch includes a light-blocking cover 400, which covers the opening of the reflective cavity 220. The light-blocking cover 400 is snapped into the light-blocking shell 200. The light-blocking cover 400 and the light-blocking shell 200 cooperate to fix the light guide 300. The light-blocking cover 400 is provided with a light-emitting hole 410, and the light-emitting part 320 is inserted into the light-emitting hole 410. With the above arrangement, the light guide 300 can be fixed in the reflective cavity 220, and it is also convenient to assemble the light guide 300 and the light-blocking cover 400 onto the light-blocking shell 200. In addition, the light-blocking cover 400 can also reflect the light incident on it back to the light guide 300, so that more light is emitted from the light-emitting part 320.
[0043] Reference Figure 2 and Figure 4 As can be imagined, in some embodiments of this utility model, the mounting part 110 is detachably connected to the light-blocking housing 200, thereby allowing the light-blocking housing 200 to be disassembled and replaced. In specific implementations, different aesthetic effects can be achieved by replacing the light-blocking housing 200 with different shapes.
[0044] Reference Figure 2 and Figure 4 As can be imagined, in some embodiments of this utility model, the light-blocking shell 200 is elastic, the lower side wall of the light guide channel 210 is provided with a slot 230, and the mounting part 110 is provided with a buckle 112, which is inserted into the slot 230. With the above-mentioned arrangement, the assembly between the light-blocking shell 200 and the mounting part 110 can be facilitated.
[0045] It is conceivable that the mounting part 110 and the light-blocking housing 200 can also be detachably connected in other ways, for example, the light-blocking housing 200 and the mounting part 110 can be screwed together.
[0046] Reference Figure 3 and Figure 4As can be imagined, in some embodiments of this utility model, the light-emitting hole 410 is circular, the light-emitting part 320 is cylindrical, the cross-sectional profile of the outer wall surface of the reflective cavity 220 is circular, and the light-blocking shell 200 is a metal part with a plating. By adopting the above-mentioned configuration, the aesthetics of the push switch can be improved.
[0047] In the specific implementation process, the light-emitting element 500 can be an LED light or other types of light source. The light emission color of the light-emitting element 500 can be selected as blue, red or other colors. Of course, the light-emitting element 500 can also be configured as a light source that can change the light emission color according to the working status of the electric kettle.
[0048] Reference Figure 6 The electric kettle according to a second aspect embodiment of the present invention includes the aforementioned push-button switch. By employing the push-button switch, the brightness of the switch can be concentrated and the light emitted is bright, thereby improving the indicating effect of the push-button switch and enhancing the visual effect of the light, thus meeting people's increasingly higher aesthetic requirements for electric kettles.
[0049] In practice, the push-button switch is mounted on the body 600 of the electric kettle in a way that allows it to rotate up and down. The push-button switch can be located below the handle 610 of the kettle body 600; however, it can also be located in other positions, which are not limited here.
[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0051] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
