Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the field of household appliances, especially an electric appliance mask and an electric appliance. BACKGROUND
[0002] As a common indoor heating device, the air-warming heater not only has the function of providing warm air, but also has the lighting function provided by the light-emitting assembly. The typical light-emitting assembly usually includes a light-emitting base, a diffusion cover, and a mask. The light-emitting base is used to fix the light source and its circuit and provide basic support for the uniform distribution of light. The diffusion cover plays the role of scattering light, so that the light is soft and uniform through the mask to avoid direct glare.
[0003] In the traditional design of the light-emitting assembly, the light-emitting base and the mask are often set separately, that is, the light-emitting base is manufactured separately and assembled on the mask. Although this design helps modular assembly and maintenance, it also brings significant increase in manufacturing cost. The separate setting means that the light-emitting base and the mask need to be manufactured separately, which increases the complexity of mold development and production line. The production of each component requires independent processes and equipment, which not only prolongs the production cycle, but also increases the difficulty of process control. In addition, due to the separate manufacturing of the light-emitting base and the mask, additional process steps are required during assembly, which also increases labor costs and assembly time. SUMMARY
[0004] The utility model discloses an electric appliance mask which has the advantages of reducing manufacturing cost and simplifying assembly process.
[0005] The above technical purpose of the utility model is achieved by the following technical scheme:
[0006] An electric appliance mask comprises:
[0007] a mask body;
[0008] a light-emitting piece comprising a light source, which is arranged on the mask body.
[0009] Further, a concave surface is arranged on the mask body, and the light source is arranged in the concave surface.
[0010] Further, a light-reflecting surface is arranged on the concave surface.
[0011] Further, an out-light diffusion plate is arranged, and the out-light diffusion plate and the concave surface form a closed chamber.
[0012] Further, the out-light diffusion plate is arranged on the mask body.
[0013] Further, the out-light diffusion plate is ultrasonic or adhesive connected with the mask body.
[0014] Further, the light-emitting diffusion plate comprises a light-emitting surface, and the projection of at least one side of the mask body on the light-emitting diffusion plate falls within the light-emitting surface.
[0015] Further, the mask body is provided with a frame, and the light-emitting diffusion plate is arranged in the region surrounded by the frame.
[0016] Another object of the present application is to provide an electric appliance with the electric appliance mask as described above.
[0017] Further, the electric appliance is a bath heater, a warmer, a clothes dryer, an air conditioner, a dehumidifier or a humidifier.
[0018] In summary, the present application has the following advantages:
[0019] First, in the present application, the light source of the light-emitting component is directly arranged on the mask body, without the need to increase the light-emitting base of the traditional light-emitting assembly. The concave surface on the mask body can be directly formed integrally with the mask body, reducing the number of parts and the investment in molds, thereby reducing the overall manufacturing cost. Moreover, the secondary assembly process between the light-emitting base and the mask body is avoided, reducing the assembly steps and the required manual operation, simplifying the production process and improving the production efficiency.
[0020] Second, in the present application, the light-emitting diffusion plate is arranged on the mask body, and the light-emitting diffusion plate and the mask body are connected by ultrasonic waves. The ultrasonic vibration generates heat through the friction of the surfaces of the two plastic components, achieving a fusion effect and forming a firm connection. The ultrasonic connection has high strength and high reliability, which can ensure the firm combination of the light-emitting diffusion plate and the mask body, and avoid the loosening or separation during use.
[0021] The light-emitting diffusion plate and the mask body can also be connected by adhesive. The adhesive can form a strong adhesive force between the two materials, and is particularly suitable for connecting different materials. This connection method not only maintains strength, but also has a certain flexibility, which can adapt to slight deformation under temperature changes or external forces.
[0022] Both connection methods can achieve good sealing effect, prevent dust, moisture or other external impurities from entering the inside of the light-emitting assembly, protect the internal light source and electronic components, and prolong the service life of the product.
[0023] Third, in the present application, the projection of at least one side of the mask body on the light-emitting diffusion plate falls within the light-emitting surface of the light-emitting diffusion plate. The side of the mask body does not exceed the range of the light-emitting surface, and the light-emitting surface is completely exposed outside under the user's visual angle, forming a frameless effect.
[0024] Fourth, in this utility model, the mask body can also have a frame, and the light diffusion plate is set in the area enclosed by the frame to form a visual effect of an extremely narrow frame. Attached Figure Description

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.
[0033] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0034] An electrical appliance face shield, such as Figure 1 As shown, the mask includes a mask body 100 and a light-emitting element, the light-emitting element including a light source 300, which is disposed on the mask body 100. There is no specific limitation on the placement of the light source 300. In this embodiment, the mask body 100 has a concave surface 102, and the light source 300 is disposed within the concave surface 102. The concave surface 102 on the mask body 100 causes the light-emitting area of the mask body 100 to be recessed. The light source 300 is disposed within the recessed portion, thus not occupying the surface space of the mask body 100 and preventing the mask body 100 from protruding outwards.
[0035] Based on the above embodiments, as a further defined embodiment, a reflective surface is also included, disposed on the concave surface 102. In this embodiment, the reflective surface on the mask body 100 is preferably a surface directly formed from the mask body 100. As an alternative embodiment, the reflective surface can also be a surface that has undergone surface treatment, such as polishing to improve the surface reflectivity. As an alternative embodiment, the reflective surface can also be coated with paint from the mask body 100 to improve reflectivity. As an alternative embodiment, the reflective surface can also have a reflective film, which is adhered to the mask body 100 to improve reflectivity.
[0036] Based on the above embodiments, as a further limiting embodiment, such as... Figure 1 and Figure 2 As shown, the electrical appliance face shield also includes a light-emitting diffuser plate 200, which is disposed on the face shield body 100, and the light-emitting diffuser plate 200 and the concave surface 102 form a closed cavity.
[0037] In this embodiment, the light source 300 is located within a closed cavity and is positioned towards the light diffuser plate 200. The specific type of light source 300 is not limited; in this embodiment, the light source 300 is preferably an LED lamp. Alternatively, the light source 300 can be one or more of the following combinations: incandescent lamp, fluorescent lamp, halogen lamp, OLED lamp, plasma light source, xenon lamp, solar light source, fiber optic light source, cold cathode fluorescent lamp (CCFL), and miniature bulb.
[0038] In this embodiment, the specific materials of the mask body 100 and the light-emitting diffuser plate 200 are not limited. Preferably, both the mask body 100 and the light-emitting diffuser plate 200 are made of plastic. Alternatively, the mask body 100 and the light-emitting diffuser plate 200 may be made of metal. In this embodiment, the mask body 100 and the light-emitting diffuser plate 200 are manufactured and produced as independent components. They need to be subsequently connected to each other using different connection methods.
[0039] In this embodiment, the light-emitting diffuser plate 200 is integrally connected to the mask body 100. The preferred integral connection in this embodiment specifically refers to an ultrasonic connection between the light-emitting diffuser plate 200 and the mask body 100. Ultrasonic vibration causes friction and heat generation between the surfaces of the two components, achieving a welding effect and forming a strong connection. As an alternative embodiment, the light-emitting diffuser plate 200 and the mask body 100 are adhesively connected. For example, an environmentally friendly adhesive can be used to connect the two.
[0040] As an alternative implementation, the mask body 100 and the light-emitting diffuser plate 200 are detachably connected by clips or bolts. Alternatively, the mask body 100 and the light-emitting diffuser plate 200 are integrally molded, meaning they are manufactured directly using a one-time injection molding method. This method involves melting different plastics of the mask body 100 and the light-emitting diffuser plate 200, injecting them separately into a mold, and then cooling them to form a single integrated structure. Alternatively, integral molding can also be achieved through 3D printing. As an alternative implementation, when the materials of the mask body 100 and the light-emitting diffuser plate 200 are metal, integral molding refers to integral die casting.
[0041] Based on the above embodiments, as a further limiting embodiment, such as... Figure 2 , 3 and Figure 4 As shown,
[0042] The light-emitting diffuser plate 200 includes a light-emitting surface 201. At least one edge of the mask body 100 is projected onto the light-emitting diffuser plate 200 and falls within the light-emitting surface 201. This ensures that the edge of the mask body 100 does not extend beyond the range of the light-emitting surface 201, and from the user's perspective, the light-emitting surface 201 is completely exposed on the outside, creating a borderless effect 101.
[0043] The specific shape of the mask body 100 is not limited; the shape of the mask body 100 can be one of the following: triangular, rectangular, square, elliptical, or circular, or a composite shape combining multiple shapes. In this embodiment, a rectangle is preferred. Figure 3 The edge shown in the viewpoint is the width of the mask body 100. As an alternative implementation, Figure 4 From a viewing angle, the projections of a portion of the two long sides and one wide side of the mask body 100 onto the light-emitting diffuser plate 200 fall within the light-emitting surface 201. The effect of the light-emitting area formed on the mask body 100 is a frameless 101 light-emitting effect.
[0044] As an alternative implementation method, such as Figure 5As shown, the mask body 100 has a frame 101, which is a framework surrounding the mask body. The frame 101 is connected to the housing to be fixed. Referring to the angle shown in the figure, the lower part of the frame 101 typically has a snap-fit structure to connect with the housing to which the mask body 100 is to be connected. In this embodiment, the light-emitting diffuser plate 200 is located within the area enclosed by the frame 101. The light-emitting diffuser plate 200 is connected to the area enclosed by the frame 101 as much as possible, that is, the edge of the light-emitting diffuser plate 200 abuts against the frame 101. A notch is provided on the edge of the frame 101 to facilitate the installation of the light-emitting diffuser plate 200. The light-emitting diffuser plate 200 and the frame 101 are connected by ultrasonic welding or adhesive bonding.
[0045] After the mask body 100 is installed, the extremely narrow frame 101 is exposed from the user's perspective, thus forming the light-emitting effect of the extremely narrow frame 101.
[0046] The specific application scenarios and methods of the electrical appliance face shields in the above embodiments are not specifically limited. This embodiment also provides an electrical appliance equipped with the aforementioned electrical appliance face shield. In this embodiment, the electrical appliance is a bathroom heater or a space heater. As an alternative embodiment, the electrical appliance is a clothes dryer, an air conditioner, a dehumidifier, or a humidifier.
[0047] The above embodiments are merely explanations of the present utility model and are not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to the embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.
