[0002] With the increasing popularity of household kitchen appliances, small appliances such as food processors are increasingly equipped with digital displays to show working status, timer information, and other features, enhancing the user experience. Existing display components are mostly installed through openings in the panel or housing, which suffers from low assembly precision, significant light leakage, and complex structures, affecting display quality and appearance. For example, Chinese patent CN216147894U discloses a light-leakage-proof food processor that uses a faceplate to completely cover the display hole, preventing light leakage between the faceplate and the display hole. While this solution improves the display effect, it is cumbersome in structure, complex in assembly, and makes it difficult to ensure the parallelism between the display module and the display area of the housing, easily causing display skew and light scattering. This utility model addresses these problems by proposing a simple, easy-to-assemble, and highly accurate display fixing and light-leakage-proof structure to overcome the shortcomings of existing technologies.

[0023] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0024] See the embodiments of this utility model. Figures 1-5As shown, a display fixing and light leakage prevention structure is disclosed, including a bottom cover 1, a housing body 2, and a display component 3. The housing body 2 has an inclined region 21 and a light-transmitting region 22 disposed in the inclined region 21. The bottom cover 1 and the housing body 2 cooperate to form an internal cavity 23. The display component 3 is disposed on the bottom cover 1 and located within the internal cavity 23 of the housing body 2. The bottom cover 1 serves as a support base for mounting the display component 3. The housing body 2 is fixed to the bottom cover 1, and its inclined region 21 is arranged parallel to the display surface of the display component 3. The light-transmitting region 22 is located in the inclined region 21, allowing the display information of the display component 3 to be transmitted through the light-transmitting region 22. Through the above structural arrangement, the precise alignment of the display component 3 and the light-transmitting region of the housing body 2 in terms of parallelism and position is ensured, thereby improving the display effect and effectively preventing light leakage.
[0025] In this embodiment, see Figures 2-4 As shown, display component 3 includes display unit 31 and display box 32. Display unit 31 is installed inside display box 32, see reference. Figure 5 As shown, the display box 32 is fixedly mounted on the bottom cover 1 to position the display unit 31, ensuring that the display unit 31 is arranged parallel to the inclined area 21 and that its display direction corresponds to the light-transmitting area 22, thereby ensuring that the displayed information can be accurately transmitted to the outside. (See reference...) Figure 2 As shown, the display unit 31 includes a circuit board 311, a display module 312, and LED beads 313. The circuit board 311 is fixed to the display box 32, and the display module 312 and LED beads 313 are fixedly mounted on the circuit board 311. The LED beads 313 are located in the peripheral area of the display module 312 to achieve the effect of supplementary lighting or indicator light for the display module 312. Optionally, the circuit board 311 and the display box 32 can be fixed by any of the following methods: screw fastening, riveting, snap locking, interference fit, or integral injection molding; the LED beads 313 can be evenly distributed in a ring, rectangle, or segmented arrangement; and the display module 312 can be a digital tube module, a segment LCD screen, or a dot matrix display screen.
[0026] See Figure 4 As shown, the display box 32 has a limiting post 321 and a fastener 322 inside. The circuit board 311 has a first through hole 100 and a second through hole 200. The fastener 322 passes through the first through hole 100 and is connected to the circuit board 311 to fix the position of the circuit board 311. The limiting post 321 passes through the second through hole 200 and cooperates with the fastener to bidirectionally position the circuit board 311 to prevent displacement during assembly, thereby improving assembly accuracy and stability. Optionally, the fastener 322 can be a screw, a snap pin, a rivet, or a stud with a snap ring structure; the limiting post 321 can be a one-piece molded plastic post, a post with a metal bushing, or a metal insert post, and the fit between it and the through hole can be a clearance fit, an interference fit, or a bushing fit.
[0027] The display box 32 has a first protrusion 323 and a second protrusion 324 on the side near the light-transmitting area 22, see reference. Figure 3 As shown, both have hollow structures extending through the light-transmitting area 22. The open end faces of the first protrusion 323 and the second protrusion 324 are close to the light-transmitting area 22 to shorten the light path and prevent light scattering. The first protrusion 323 is arranged around the outer edge of the display module 312, forming an enclosure and limiting of the display module 312. The lamp bead 313 is inserted inside the second protrusion 324, so that the light beam emitted by it is limited in direction by the open end face of the second protrusion 324. The top surface of the display module 312 is higher than the open end face of the first protrusion 323, so that the display module 312 is in an exposed position in the installation space defined by the first protrusion 323, thereby allowing the display information to be fully displayed through the light-transmitting area, avoiding the loss of display content or blurring of edges due to structural obstruction. The top of the lamp bead 313 is lower than the open end face of the second protrusion 324, so that the second protrusion 324 covers and blocks the lamp bead 313, limiting the outward direction of light leakage. Optionally, the boss can be ring-shaped, elliptical, polygonal, or composed of multiple segmented arcs; the proximity can be direct contact or a small gap can be left to prevent stress transmission.
[0028] The display box 32 is provided with a mounting part 325, see reference. Figure 3 and Figure 5 As shown, the mounting part 325 and the bottom cover 1 can be fixed and positioned by various methods such as snap fasteners, screws, slot-spring cooperation, and rotary locks; the mounting part 325 can also be equipped with thickened ribs, limiting shoulders or elastic tongues to improve the positioning accuracy and overall stability during assembly.
[0029] See Figure 5 As shown, the bottom cover 1 is provided with a flange 11, which is located in the peripheral area of the display box 32. The flange 11 is used to assist in the assembly and positioning of the display box 32, and can be used as a positioning stop or a limiting structure. Optionally, the flange 11 can be a continuous ring, segmented, or several independent positioning blocks, and a guide slope or rounded transition can be provided on the contact surface with the outer shell of the display box for insertion and positioning.
[0030] The light-transmitting area 22 includes a thinning section 221, see reference. Figure 1 As shown, the thickness of the thinned portion 221 is less than the thickness of other areas of the body 2, so that the display information can be clearly presented through the light-transmitting area 22. Optionally, the thinned portion 221 can be uniformly thinned, partially thinned, or thinned in a stepped transition. The surface can be textured, frosted, or polished to adjust the light diffusion effect. The shape can be circular, rectangular, elliptical, or strip-shaped.
[0031] In some other embodiments, the light-transmitting area 22 may be made of a separate light-transmitting component, such as a transparent PC board, acrylic board or glass sheet, and installed on the inclined area 21 of the box body 2 by means of clips, screws or adhesives, so as to facilitate the replacement and customization of display windows of different colors or light transmittances.
[0032] In some other embodiments, the display component 3 may be designed as an integral detachable module corresponding to the light-transmitting area 22, including the display unit 31 and the display box 32, and connected to the bottom cover 1 through a quick release structure such as a slide rail buckle and a rotary lock, so that the display component can be replaced or upgraded separately without disassembling the whole machine, which is convenient for maintenance and can be adapted to display modules with different functions according to needs.
[0033] See Figure 1 and Figure 6 As shown, this utility model also relates to a shredder, which includes a motor cover 4, a motor 5, and a display fixing and light-leakage-proof structure. The motor 5 is mounted on the bottom cover 1, and the motor cover 4 is also mounted on the bottom cover 1 and covers the motor 5, thereby providing effective isolation and protection for the motor 5 during operation. The motor cover 4 not only prevents the electrical sparks and heat generated when the motor starts and stops from being conducted outward, but also reduces the noise of the motor during operation, improving the safety of the whole machine and the user experience. The display component 3 is located in the outer area of the motor cover 4 and cooperates with the housing body 2, so that the display component 3 and the display direction of the light-transmitting area 22 are consistent. Since the motor cover 4 is located in the internal cavity 23 of the housing body 2, it ensures the working space of the motor 5 without interfering with the parallel cooperation between the display component 3 and the housing body 2, thereby maintaining the accurate presentation of the displayed information. Through this overall structure, the shredder can achieve stable positioning of the display component 3 and prevent light leakage, while also ensuring the working safety and quiet operation of the motor 5, thereby significantly improving the overall performance and user experience of the whole machine.
[0034] Optionally, the motor cover 4 can be made of plastic injection molding, metal stamping, or composite sound insulation material; its connection with the bottom cover 1 can be by snap-fit, screw, twist lock, or elastic latch. The motor 5 can be a series-wound motor, a permanent magnet DC motor, or an AC induction motor. The outer surface of the motor cover 4 can be provided with heat dissipation holes, air guide slots, or sound insulation lining to further optimize the heat dissipation and noise reduction performance of the shredder.
[0035] In summary, the display fixing and light-leakage prevention structure and shredder provided by this utility model have the following technical effects: (1) The display components are fixedly installed on the bottom cover and arranged parallel to the inclined area of the box body, so that the display components can be automatically and accurately aligned with the light-transmitting area during the assembly process, ensuring that the display information is clearly transmitted at the correct angle, effectively improving the display effect and avoiding display skew and light scattering problems caused by parallelism deviation.
[0036] (2) A light-transmitting area of the thinned part is set in the inclined area of the box body, and together with the first protrusion surrounding the display module and the second protrusion through which the LED beads are inserted, the light output path is effectively limited, which not only improves the light transmission efficiency, but also prevents the side leakage and cross-lighting of the LED beads; the height setting of the first protrusion makes the display area clear and the boundary neat, while the second protrusion forms a geometric blockage, further limiting the direction of light leakage, thereby significantly improving the display contrast and visual quality.
[0037] (3) The display box is double fixed and precisely positioned with the circuit board by limiting posts and fasteners to prevent displacement caused by vibration or thermal expansion and contraction; the flange on the bottom cover assists in positioning, simplifies the assembly process and improves the positioning accuracy, ensuring stability and consistency during mass production.
[0038] (4) In the shredder, the motor cover covers the motor and is fixedly connected to the bottom cover, so that the display components and the motor are arranged in separate spaces. This not only prevents the impact of sparks and heat on the display components when the motor starts and stops, but also reduces operating noise and improves the safety and user experience of the whole machine.
[0039] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
