[0003] This kind of traditional water cup brush has certain limitation in actual use. Since the brush head adopts rigid structure and cannot be deformed, although the scattered bristles at the bottom of the brush head can contact the cup bottom to realize the cleaning function, the effective contact area of the brush head with the cup bottom is very small. When stubborn stains such as tea stains appear on the cup bottom, even if the user squeezes the brush head to the cup bottom, the applied force is difficult to be fully transmitted to the scattered bristles at the bottom, so that the cleaning strength of the bristles on the stubborn stains is insufficient, which greatly affects the stain cleaning effect. In addition, the contactable area of the brush head bottom with the cup bottom is small each time during the cleaning process, which leads to low cleaning efficiency and makes it difficult to quickly complete the cleaning of the water cup, bringing many inconveniences to the user and failing to meet the demand of people for efficient and convenient cleaning of the water cup.

Detailed Implementation

[0022] This utility model provides a cup bottom brush. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0023] Please see Figures 1 to 5 This utility model provides a cup bottom brush, including an inner straight rod 11, an inner flat block 12 disposed at the bottom end of the inner straight rod 11, a silicone handle 2 covering the inner straight rod 11, and a brush head 3 covering the inner flat block 12. The brush head 3 includes a silicone flat body 31 and silicone bristles 32 disposed on the outer peripheral surface of the silicone flat body 31. The inner flat block 12 is located at the upper and middle parts of the silicone flat body 31, and the lower part of the silicone flat body 31 can be elastically bent.

[0024] When using this cup-bottom brush to clean the water cup 6, the user holds the silicone handle 2, which drives the brush head 3 into the water cup 6. Because the lower part of the silicone flat body 31 of the brush head 3 can bend elastically, when the bottom of the silicone flat body 31 contacts the bottom of the cup and pressure is applied, the lower part will elastically bend according to the shape of the bottom of the cup, allowing the silicone flat body 31 to better conform to the surface of the bottom of the cup. Simultaneously, the silicone bristles 32 on the outer circumference of the silicone flat body 31 can also make contact with the bottom of the cup over a large area. During the cleaning process, the pressure applied by the user is transmitted to the silicone flat body 31 through the inner straight rod 11 and the inner flat block 12. The elastic deformation of the silicone flat body 31 evenly distributes the pressure onto the silicone bristles 32, thereby enhancing the cleaning power of the silicone bristles 32 on the stains on the bottom of the cup. By rotating the water cup or rotating the silicone handle 2 to change the cleaning position, effective cleaning of the bottom of the cup can be achieved. After cleaning the bottom of the cup, the bottom brush is removed from the bottom of the cup, and the silicone flat body 31 automatically elastically deforms and returns to its original shape. The silicone bristles 32 on the outer peripheral surface of the silicone flat body 31 face the side wall of the cup 6 (i.e., the cup body) and continue to clean the side wall of the cup 6.

[0025] Compared with existing technologies, the silicone flat body 31 of the cup bottom brush provided by this utility model can be elastically bent at the lower part, allowing the silicone bristles 32 on the lower part of the silicone flat body 31 to fit tightly against the bottom of the cup. The force applied by the user can be effectively transmitted to the silicone bristles 32. When stubborn stains such as tea stains appear on the bottom of the cup, the silicone bristles 32 can obtain stronger cleaning power, significantly improving the cleaning effect on stubborn stains and ensuring the cleanliness and hygiene of the water cup 6. In addition, the contact area between the brush head 3 and the bottom of the cup is greatly increased, so that each contact with the bottom of the cup can cover a larger area during the cleaning process, reducing the number of repeated scrubbing, thereby quickly completing the cleaning of the water cup 6, greatly improving cleaning efficiency, meeting people's needs for efficient and convenient cleaning of the water cup 6, and bringing a better user experience.

[0026] In one embodiment, the silicone flat body 31 has silicone bristles 32 densely distributed on one end face and the other end face. The silicone bristles 32 on both ends can participate in the cleaning work alternately or simultaneously, evenly distributing the cleaning pressure and friction wear, and avoiding excessive wear of the silicone bristles 32 in some areas. Even if the silicone bristles 32 on one end face show slight wear, the silicone bristles 32 on the other end face can still maintain good cleaning performance, allowing the cup bottom brush to maintain a highly efficient cleaning state for a longer period of time, and significantly extending the effective cleaning cycle.

[0027] See Figure 2 and Figure 5 In another embodiment, one end face of the silicone flat body 31 is densely covered with silicone bristles 32, while the other end face is provided with multiple raised strip groups 4 and rounded convex groups 5. The structural design of the raised strips 41 and rounded convex groups 51 provides stronger physical friction compared to the bristles. When cleaning stubborn stains such as tea stains, coffee stains, and oil stains, the raised strips 41 can penetrate deep into the gaps between the stains and the surface of the tableware in a linear scraping manner, gradually peeling off the stubborn stains; the rounded convex groups 51, with their point-like concentrated force characteristics, can specifically squeeze and rub the stains, destroying the adhesion structure of the stains. The two work together to efficiently break down various stubborn stains, significantly improve the cleaning effect, and make the cleaning process more labor-saving and easier to operate.

[0028] Furthermore, a rounded convex group 5 is provided between two adjacent convex strip groups 4. The convex strip groups 4 and the rounded convex groups 5 are staggered to form a tight and uniform cleaning array. When cleaning stubborn stains, the convex strip groups 4 first use the strong scraping force of the convex edges to initially separate the stains, and then the rounded convex groups 5 squeeze and break up the scattered stains to prevent stains from remaining or spreading. This alternating action mode can more efficiently break down stains, and compared with the traditional independently set cleaning structure, it greatly improves the overall cleaning efficiency.

[0029] In a preferred embodiment, the convex strip group 4 includes several horizontally extending and vertically spaced convex strips 41, and the circular convex group 5 includes a rectangular array of circular convex strips 51. The horizontally extending convex strip group 4 can efficiently perform linear scraping along the horizontal texture or stain distribution direction of the tableware surface during cleaning. For example, when cleaning horizontal ring-shaped stains on the cup wall, the convex strips 41 can quickly peel off the stains with continuous and stable scraping action along the stain's extension direction; while the vertically spaced arrangement ensures that there are appropriate gaps between the convex strips 41, which not only avoids mutual interference but also allows the scraped stains to be discharged in time, preventing secondary adhesion. The circular convex group 5 adopts a rectangular array arrangement, so that the point-like force of the circular convex strips 51 evenly covers the cleaning area. When squeezing and rubbing stubborn stains, it can precisely exert force from multiple directions, enhancing the stain-destructive effect, achieving directional and targeted cleaning action, and significantly improving cleaning efficiency.

[0030] Preferably, the bottom edge of the silicone flat body 31 has a U-shaped structure. The U-shaped bottom edge can precisely fit the curved edge of the cup bottom, the junction between the cup wall and the cup bottom, and other cleaning dead corner areas. When cleaning such areas, traditional brush heads 3 are limited by their edge shape, making it difficult to completely cover and effectively remove stains, and easily leaving dirt residue. However, the U-shaped bottom edge can reach into corners, allowing the silicone bristles 32 and the raised strip group 4 and rounded raised group 5 to fully contact the stains. Whether it is tea stains on the curved corner of the cup bottom or oil stains in the crevices at the bottom of the cup wall, they can be thoroughly cleaned, greatly improving the thoroughness of cleaning, eliminating cleaning blind spots, and ensuring that all parts of the tableware meet the cleanliness standard.

[0031] Preferably, the silicone flat body 31 has silicone bristles 32 arranged on its sides. The addition of side bristles allows the user to cover more areas in a single cleaning action, reducing cleaning steps and repetitive operations. For example, when cleaning a tall cup, there is no need to adjust the angle of the brush head 3 multiple times or repeatedly insert it into the cup 6; a single up-and-down movement of the brush head 3 can clean both the bottom and the inner side of the cup simultaneously, significantly shortening cleaning time and improving cleaning efficiency.

[0032] Preferably, the top of the silicone handle 2 is provided with a hanging hole 21. The cup bottom brush can be hung on the kitchen wall or hook through the hanging hole 21 for easy storage and drainage for antibacterial purposes.

[0033] In this embodiment, the inner straight rod 11 and the inner flat block 12 are made of stainless steel casting. Stainless steel has high strength and good rigidity. The stainless steel casting of the inner straight rod 11 and inner flat block 12 provides a stable support structure for the cup bottom brush. During the cleaning process, even if the user applies greater pressure to clean stubborn stains, the inner straight rod 11 and inner flat block 12 are not easily bent or deformed, ensuring that the brush head 3 can stably transmit cleaning force. This allows the silicone bristles 32, the raised strip group 4, and the rounded raised group 5 to effectively perform their cleaning function, maintaining the normal performance of the cup bottom brush and improving the product's durability.

[0034] The handle is longer than the brush head 3. During the cleaning process, the user can flexibly adjust the hand position and force angle according to the cleaning needs. By using the lever principle, the brush head 3 can be driven to clean efficiently with less force. Especially when dealing with stubborn stains that require greater force, the long handle can effectively distribute hand pressure, reduce the burden on the wrist and arm, make the cleaning operation easier and less strenuous, and improve the comfort of long-term cleaning operations.
