Description

Technical Field

[0001] This utility model relates to the field of road sweeping technology, specifically to a sweeping brush, a sweeping disc, and a sweeping vehicle. Background Technology

[0002] A sweeper is a specialized road cleaning equipment, mainly used for cleaning roads, streets and other public areas. Its working principle is to use a rotating sweeping disc to drive a brush to collect road debris.

[0003] Existing sweeping brushes are typically made of pure plastic or plastic with added steel plates. However, pure plastic brushes have soft bristles, insufficient rigidity, and poor wear resistance, resulting in poor cleaning performance at high speeds and requiring frequent replacements, increasing maintenance costs. As for brushes with added steel plates, the different wear rates of the two types of bristles mean that at high speeds, the plastic bristles wear out faster, making the steel bristles more susceptible to breakage under stress, thus affecting traffic safety.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0041] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0043] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] As described in the background section, existing sweeping brushes are typically made of pure plastic or contain steel plates within a plastic brush. However, the inventors have discovered that pure plastic brushes have soft bristles and insufficient rigidity. When the sweeper operates at high speeds, the bristles fly around as the sweeper disc rotates, making it difficult for them to contact the ground and resulting in poor cleaning performance. Furthermore, plastic bristles have poor wear resistance and require frequent replacement, increasing maintenance costs. Regarding the method of adding steel plates to plastic brushes, the different wear rates of the two types of bristles mean that during high-speed operation, the plastic bristles wear out faster, causing the steel bristles to be prone to breakage due to individual stress. Broken steel pieces falling to the ground pose a risk of punctures, flying debris, and injury, impacting traffic safety.

[0047] Based on this, please refer to Figures 1-8 This utility model provides a sweeping brush 100, a sweeping disc 1100, and a sweeper 1000, which can effectively improve the aforementioned technical problems. Specifically, the sweeping bristles have high overall rigidity and wear resistance, improving cleaning effect and safety while reducing the risks and maintenance costs of vehicle operation. The sweeping brush 100, sweeping disc 1100, and sweeper 1000 will be described in detail below.

[0048] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of the sweeper 1000 provided in this embodiment, combined with... Figure 1 The sweeper 1000 includes a sweeping disc 1100 and a vehicle body 1200. The sweeping disc 1100 is mounted on the vehicle body 1200. As is easy to understand, the sweeping disc 1100 is used to sweep up garbage on the road surface while the vehicle body 1200 is in motion.

[0049] For details, please refer to Figure 2 and Figure 3 , Figure 2 This is a first-view structural diagram of the scanning disk 1100 provided in this embodiment. Figure 3 This is a structural schematic diagram of the sweeping disk 1100 provided in this embodiment from a second perspective. (Combined with...) Figure 2 and Figure 3The sweeping plate 1100 includes a sweeping brush 100 and a mounting base 200, with the sweeping brush 100 mounted on the mounting base 200.

[0050] It should be noted that there are multiple sweeping brushes 100, which are arranged at intervals along the circumference of the mounting base 200 to improve the cleaning effect.

[0051] As will be readily apparent to those skilled in the art, the sweeping disc 1100 may also include a drive assembly for driving the mounting base 200 to rotate, thereby causing the sweeping brush 100 to rotate, in order to sweep away debris on the road surface. Of course, the sweeping disc 1100 may also include other structures such as a suction cup assembly and a water spray assembly, which will not be described in detail in this embodiment.

[0052] Please refer to Figures 4-6 , Figure 4 This is a first-view structural diagram of the brush 100 provided in this embodiment. Figure 5 This is a structural schematic diagram of the sweeping brush 100 from a second perspective provided in this embodiment. Figure 6 for Figure 4 Sectional view of section AA in the image. Combined with... Figures 4-6 The sweeping brush 100 includes a sweeping brush base 10, multiple plastic bristles 20 and multiple mixed bristles 30, all of which are disposed on the sweeping brush base 10, which is mounted on the mounting base 200.

[0053] Further, please refer to Figure 7 , Figure 7 This is a cross-sectional view of the hybrid brushing 30 provided in this embodiment, combined with... Figure 7 The mixed bristle 30 includes metal bristles 31 and a plastic protective sleeve 32, with the plastic protective sleeve 32 covering the metal bristles 31.

[0054] Combination Figures 4-7 Understandably, by combining multiple plastic bristles 20 and multiple mixed bristles 30 on the brush holder 10, the overall rigidity of the bristles is strengthened, and their wear resistance is improved. During high-speed operation, the bristles are less likely to fly away, thus improving the cleaning effect and reducing the need for frequent bristle replacement, thereby lowering maintenance costs. Simultaneously, the plastic protective sleeve 32 provides protection by covering the metal bristles 31, making them less prone to breakage during contact with the ground, improving operational safety and reducing the risks associated with vehicle operation.

[0055] To improve wear resistance and cleaning effect, the number of metal bristles 31 can be set to multiple, and the multiple metal bristles 31 are twisted together in a braided shape. By twisting the multiple metal bristles 31 into a braided shape and then covering them with a plastic protective sleeve 32, the structural strength of the resulting mixed bristle 30 is increased, and the multiple metal bristles 31 inside are not easily deformed or broken, thereby improving the cleaning effect. The simultaneous contact of multiple metal bristles 31 with the ground also increases the overall wear resistance of the mixed bristle 30.

[0056] It should be noted that in this embodiment, the number of metal bristles 31 is specifically seven; of course, in other embodiments, the number of metal bristles 31 can be one, two, three, four or five, etc., and the specific number needs to be determined according to the actual use and design requirements.

[0057] Furthermore, it should be noted that the metal bristles 31 in this embodiment are specifically steel wires, which have the characteristics of high wear resistance and high hardness. In this embodiment, multiple steel wires are twisted together to form a wire rope, and then covered by a plastic protective sleeve 32. This prevents the mixed bristles 30 from cracking, breaking, falling off, or fraying due to wear, thereby improving the cleaning effect, reducing the risk during vehicle operation, and ensuring traffic safety.

[0058] Of course, in some other embodiments, the metal bristles 31 can also be made of other materials such as stainless steel wire, copper wire, aluminum wire, alloy wire, etc.

[0059] Please continue to combine Figure 6 Multiple installation spaces 40 are formed between multiple plastic bristles 20, and the multiple installation spaces 40 are spaced apart. Each installation space 40 contains at least one mixed bristle 30. By setting up the installation spaces 40, multiple plastic bristles 20 are arranged around each mixed bristle 30. In actual cleaning, the brush 100 rotates under the drive of the mounting base 200, so that the mixed bristles 30 and plastic bristles 20 abut against each other after contacting the ground. This interaction makes the two less prone to deformation and ensures the uniformity of wear of the plastic bristles 20 and mixed bristles 30, thereby improving the cleaning effect.

[0060] To further improve wear uniformity and cleaning effect, multiple installation spaces 40 are evenly spaced, and the number of mixed bristles 30 in each installation space 40 is the same. This arrangement ensures that the multiple plastic bristles 20 and multiple mixed bristles 30 are evenly distributed on the brush holder 10, resulting in more uniform force distribution upon contact with the ground. This guarantees that the wear rate of each bristle is basically consistent, preventing uneven wear and ensuring that each bristle makes uniform contact with the ground during cleaning, thus improving the cleaning effect.

[0061] It should be noted that in this embodiment, there are six installation spaces 40, and each installation space 40 contains two mixed bristle brushes 30. Of course, in other embodiments, the number of installation spaces 40 can be one, two, three, or four, etc., and the number of mixed bristle brushes 30 in each installation space 40 can also be one, two, three, or four, etc.

[0062] Furthermore, in this embodiment, the length of the plastic bristles 20 is greater than the length of the mixed bristles 30. It is understood that the plastic bristles 20 have a lower hardness than the mixed bristles 30, meaning they are softer. When the sweeper 1000 operates at high speed, the plastic bristles 20 are prone to flying off during rotation. Therefore, it is necessary to adjust the height of the plastic bristles 20 to ensure they are pressed firmly against the ground. This embodiment, by setting the length of the plastic bristles 20 to be greater than the length of the mixed bristles 30, ensures that both the plastic bristles 20 and the mixed bristles 30 are in contact with the ground simultaneously, resulting in consistent wear on both and thus improving the cleaning effect.

[0063] Optionally, the ratio of plastic bristles 20 to mixed bristles 30 is 1.1 to 1.3. For example, the ratio can be 1.1, 1.15, 1.2, 1.25, or 1.3. Within this ratio range, the wear consistency of the plastic bristles 20 and the mixed bristles 30 is better, resulting in a better cleaning effect.

[0064] Please continue to combine Figure 2 and Figure 3 When sweeping the road, in order to ensure that the garbage or dust on the road can be effectively swept to the middle of the vehicle body 1200, so that it can be easily suctioned by the suction cup assembly, the sweeping brush 100 is usually tilted at a certain angle. That is, the sweeping brush 100 has a certain tilt angle.

[0065] Thus, in order to ensure that multiple plastic bristles 20 can simultaneously contact the ground during the sweeping process, thereby guaranteeing the cleaning effect, combined with... Figures 2-5 In this embodiment, the length of the plurality of plastic bristles 20 decreases sequentially along the length direction of the brush seat 10.

[0066] Similarly, in order to ensure that multiple mixed bristles 30 can contact the ground simultaneously, in this embodiment, the length of multiple mixed bristles 30 decreases sequentially along the length direction of the brush seat 10.

[0067] It should be noted that the length direction of the brush holder 10 is... Figure 2 As shown in the figure, the width direction of the brush holder 10 is in the X direction. Figure 3 The Y direction is shown in the figure.

[0068] Please refer to Figure 8 , Figure 8 This is a cross-sectional view of the plastic bristle brush 20 provided in this embodiment, combined with... Figure 8 In this embodiment, the cross-sectional shape of the plastic bristles 20 is elliptical. By setting it to an elliptical structure, the contact area between the plastic bristles 20 and the ground can be increased, thereby improving the cleaning effect.

[0069] Optionally, the ratio of the major axis a to the minor axis b of the ellipse is 1.4 to 1.6. For example, the ratio can be 1.4, 1.45, 1.5, 1.55, or 1.6, etc. Within this range, the cleaning effect of the plastic bristles 20 is better.

[0070] Of course, in some other embodiments, the cross-sectional shape of the plastic bristles 20 may also be circular. Optionally, the diameter of the circle is 2mm to 5mm. For example, the diameter of the plastic bristles 20 may be 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, or 5mm, etc.

[0071] Optionally, in this embodiment, the diameter of the metal bristles 31 is 1mm to 1.5mm. For example, the diameter of the metal bristles 31 can be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, or 1.5mm, etc.

[0072] Optionally, in this embodiment, the diameter of the mixed bristle 30 is 4mm to 6mm. For example, the diameter of the mixed bristle 30 can be 4mm, 4.5mm, 5mm, 5.5mm, or 6mm, etc.

[0073] Additionally, it should be noted that in this embodiment, the plastic bristles 20 are specifically made of polypropylene, and the plastic protective sleeve 32 is also specifically made of polypropylene. Polypropylene has characteristics such as fatigue resistance, corrosion resistance, heat resistance, lightweight, and ease of processing. Of course, in other embodiments, the plastic bristles 20 can also be made of other plastic materials such as nylon or polyethylene, and similarly, the plastic protective sleeve 32 can also be made of other plastic materials such as nylon or polyethylene.

[0074] In summary, the embodiments of this utility model provide a sweeping brush 100, a sweeping disc 1100, and a sweeper 1000. The sweeping brush 100 includes a brush base 10, multiple plastic bristles 20, and multiple mixed bristles 30. The multiple plastic bristles 20 are disposed on the brush base 10, and the multiple mixed bristles 30 are disposed on the brush base 10. The mixed bristles 30 include metal bristles 31 and a plastic protective sleeve 32, with the plastic protective sleeve 32 covering the metal bristles 31. By setting multiple plastic bristles 20 and multiple mixed bristles 30 on the brush base 10 for cooperation, the overall rigidity of the sweeping bristles is strengthened, the wear resistance is higher, and the bristles are less likely to fly away during high-speed operation, which can improve the sweeping effect and reduce the need for frequent bristle replacement, thereby reducing maintenance costs. At the same time, the plastic protective sleeve 32 has a protective function. By covering the metal bristles 31, the metal bristles 31 are less likely to break during contact with the ground, which can improve operational safety and reduce the risk of vehicle operation.

[0075] The sweeping plate 1100 includes a sweeping brush 100, which has all the functions and benefits of the sweeping brush 100.

[0076] The sweeper 1000 includes a sweeping disc 1100, which has all the functions and benefits of the sweeping disc 1100.

[0077] The above description is merely a specific embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
