Cleaning apparatus and floor brush assembly

Abstract

This application provides a cleaning device and a floor brush assembly. A spray nozzle, a first scraper, and a second scraper are sequentially arranged along the rotation direction of the roller brush. The contact point between the roller brush and the surface to be cleaned is located between the second scraper and the spray nozzle in the rotation direction of the roller brush. Droplets falling outward from the first scraper are guided to the roller brush and do not fall onto the surface to be cleaned, effectively reducing dripping. Furthermore, due to the second scraper, the cleaning medium is more evenly distributed on the roller brush compared to a single first scraper, resulting in a better cleaning effect. Since more cleaning medium adheres to the roller brush, the number of droplets at the first and second scrapers is reduced, and the number of droplets falling when the roller brush stops rotating or is pulled backward is also reduced. Simultaneously, this design also reduces the loss of cleaning medium due to dripping, improving the utilization rate of the cleaning medium.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0043] This application provides a cleaning device and a floor brush assembly, which are described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0044] Please see Figures 1 to 2 The embodiments of this application provide a cleaning device 100, which includes a base 110, a roller brush cover 120, a roller brush 130, a spraying assembly 140, a first scraper 150, and a second scraper 160.

[0045] The base 110 and the brush cover 120 are the main carriers for supporting other components. The brush cover 120 and the base 110 are connected to each other to form a brush cavity 111. Typically, a dust collection port 112 is provided at the bottom of the brush cavity 111 to allow dust and other foreign objects to enter.

[0046] The roller brush 130 is rotatably disposed within the roller brush cavity 111 to lift dust and other foreign objects and clean a surface 300 to be cleaned. Generally, please refer to... Figure 2 The roller brush 130 includes a base 131 and bristles 132. The base 131 is generally cylindrical, and the bristles 132 are disposed on the outer periphery of the base 131 and extend radially outward from the base 131. Here, when the cleaning device 100 is cleaning a surface 300 to be cleaned, the rotation direction of the roller brush 130 is a first direction, i.e. Figure 2 In direction A.

[0047] The spray assembly 140 has a spray nozzle 141 disposed within the roller brush cavity 111, which is used to spray a cleaning medium onto the roller brush 130 to improve the cleaning effect on the floor and / or to clean the roller brush 130. For details, please refer to [link to relevant documentation]. Figure 2 The spray assembly 140 includes a liquid supply line (not shown) and a spray nozzle 141. The inlet end of the liquid supply line is connected to a liquid storage container (not shown), which is used to hold the cleaning medium. The liquid storage container can be independent of the base 110 or mounted on the base 110. The outlet end of the liquid supply line is connected to the spray nozzle 141 to provide the cleaning medium to the spray nozzle 141, which is located within the roller brush cavity 111. The spray nozzle 141 can spray the cleaning medium onto the roller brush 130 located within the roller brush cavity 111. Furthermore, the spray nozzle 141 can be equipped with a nozzle or similar device to achieve a better spraying effect.

[0048] The first scraper 150 is disposed within the brush cavity 111 and extends along the axial direction of the brush 130. Specifically, please refer to... Figure 2 The first scraper 150 is connected to the roller brush cover 120. In other embodiments, the first scraper 150 may also be connected to the base 110. The free end of the first scraper 150 is press-fitted with the roller brush 130. When the roller brush 130 rotates, the first scraper 150 abuts against the roller brush 130 and cleans the roller brush 130.

[0049] In use, the spray assembly 140 sprays cleaning medium onto the roller brush 130, which rotates in a first direction, causing the cleaning medium on it to rotate synchronously. Here, the roller brush 130, located away from the spray nozzle 141, contacts the first scraper 150 during rotation. The first scraper 150 is interference-fitted with the roller brush 130, ensuring the cleaning medium is evenly distributed on the roller brush 130. However, droplets may still accumulate at the contact point between the first scraper 150 and the roller brush 130. These droplets may fall onto the surface 300 to be cleaned for various reasons, causing dripping.

[0050] Therefore, in the embodiments of this application, the cleaning device 100 is further provided with a second scraper 160, which is disposed within the roller brush cavity 111 and extends along the axial direction of the roller brush 130. Specifically, please refer to... Figure 2 The second scraper 160 is connected to the roller brush cover 120. In other embodiments, the second scraper 160 may also be connected to the base 110. The free end of the second scraper 160 is press-fitted with the roller brush 130. When the roller brush 130 rotates, the second scraper 160 abuts against the roller brush 130 and cleans the roller brush 130.

[0051] Please continue reading here. Figure 2 The spray nozzle 141, the first scraper 150, and the second scraper 160 are in the first direction (i.e., Figure 2 The roller brush 130 is arranged sequentially in the first direction (A), and the contact position between the roller brush 130 and the first scraper 150 is located between the second scraper 160 and the spray nozzle 141 in the first direction. That is, as the roller brush 130 rotates, the cleaning medium leaving the spray nozzle 141, after being sprayed onto the roller brush 130, will pass sequentially through the first scraper 150 and the second scraper 160 before reaching the surface to be cleaned 300.

[0052] During use, droplets falling outward from the first scraper 150 along the first direction are blocked by the second scraper 160. Here, these droplets are guided by the second scraper 160 to contact the roller brush 130 and adhere evenly to the roller brush 130. That is, the outwardly falling droplets are guided to the roller brush 130 and do not fall onto the surface to be cleaned 300, effectively reducing dripping. Moreover, since more cleaning medium is adhered to the roller brush 130, the number of droplets at the first scraper 150 and the second scraper 160 is reduced, and the number of droplets falling when the roller brush 130 stops rotating or is pulled backward is also reduced accordingly.

[0053] Meanwhile, due to the arrangement of the second scraper 160, compared with the single first scraper 150, the cleaning medium is more evenly distributed on the roller brush 130, so as to achieve a better cleaning effect, while also reducing the loss of cleaning medium caused by dripping and improving the utilization rate of cleaning medium.

[0054] Here, when the first scraper 150 is not located above the second scraper 160, for example, when both are located on either side of the roller brush 130 and at the same height, or when the position of the first scraper 150 can be lower than the second scraper 160, the first scraper 150 and the second scraper 160 can achieve the effect of evenly distributing the cleaning medium, and the second scraper 160 can also block droplets driven by the roller brush 130 and moving along the first direction. However, the second scraper 160 does not have a good blocking effect on droplets dripping downwards from the first scraper 150 that do not move along the first direction. Therefore, in some embodiments, please refer to... Figure 2 The forward direction is defined by the direction in which the cleaning device 100 moves while cleaning the surface 300 to be cleaned (i.e., the forward direction is defined by the direction in which the cleaning device 100 moves while cleaning the surface 300 to be cleaned). Figure 2 In the B direction, the first scraper 150 and the second scraper 160 are both located on the front side of the roller brush 130, such that the first scraper 150 is located on the upper side of the second scraper 160.

[0055] At the same time, Figure 2In this embodiment, the spray nozzle 141 is also located on the front side of the roller brush 130 and above the first scraper 150. After the cleaning medium is applied, the roller brush 130 can promptly contact the first scraper 150 and the second scraper 160, so that the cleaning medium is evenly distributed on the roller brush 130. Furthermore, after the cleaning medium is evenly distributed, the roller brush 130 can quickly contact the surface 300 to be cleaned, achieving a good cleaning effect. In other embodiments, the spray nozzle 141 can also be located on the other side of the roller brush 130. However, it is understood that a closer distance between the first scraper 150 and the spray nozzle 141 in the first direction will achieve a better squeegee effect, and a higher position of the spray nozzle 141 will also achieve a better spraying effect.

[0056] Here, when the water droplets formed at the first scraper 150 drip downwards due to gravity, they will drip onto the second scraper 160 below them, instead of dripping directly onto the surface 300 to be cleaned. These droplets, guided by the second scraper 160, can then re-adhere to the roller brush 130, thereby reducing dripping and improving the utilization rate of the cleaning solution.

[0057] Here, when the second scraper 160 is located below the first scraper 150, the second scraper 160 may come into contact with the ground, thereby preventing larger particulate foreign objects from entering the brush chamber 111. Therefore, in some embodiments, please refer to... Figures 2 to 3 The second scraper 160 is located on the front side of the roller brush 130, and the second scraper 160 is close to the surface to be cleaned 300. Please refer to [further details]. Figure 4 The second scraper 160 has a plurality of gaps 161 spaced apart. It is understood that in other embodiments, if the first scraper 150 is located close to the surface to be cleaned 300, the first scraper 150 may also have the gaps 161.

[0058] Here, the gap 161 is designed to improve the deformation capability of the second scraper 160, making it easier for the second scraper 160 to lift upwards when it encounters dust particles, so that the dust particles are not blocked on the front side of the second scraper 160 and can enter the roller brush cavity 111. The size of the gap 161 can be adjusted according to actual needs to maintain good cleaning ability.

[0059] In some embodiments, please refer to Figure 5The first scraper 150 and the second scraper 160 are configured as a single unit, which can be connected to the base 110 or the roller brush cover 120. This eliminates the need for separate installation of the first scraper 150 and the second scraper 160, simplifying installation and facilitating later disassembly, maintenance, and replacement. It is understood that in other embodiments, the first scraper 150 and the second scraper 160 may also be connected to the base 110 or the roller brush cover 120 respectively; this embodiment does not constitute a limitation.

[0060] For example, the first scraper 150 and the second scraper 160 are integrally manufactured by injection molding or other integral molding processes to form the integral structure. For another example, the first scraper 150 and the second scraper 160 are connected to a connecting seat by bolts, snap-fit ​​connections, or other connection methods to form an integral structure, and the connecting seat is connected to the base 110 or the roller brush cover 120.

[0061] In some embodiments, the free end of the second scraper 160 extends toward the roller brush 130 and is tangential to the roller brush 130. Here, the free end of the second scraper 160 is not perpendicular to the roller brush 130 but is approximately tangential to the roller brush 130, so that dust and other foreign objects do not easily accumulate in the space between the roller brush cover 120 and the second scraper 160, and excessive water does not easily accumulate, resulting in the formation of excessively large water droplets.

[0062] For example, please refer to Figures 2 to 3 The free end of the second scraper 160 extends toward and is tangential to the roller brush 130, and the free end of the second scraper 160 extends at a generally downward angle, so that the liquid accumulated at the second scraper 160 can be guided to the roller brush 130 in a timely manner, and is not prone to excessive accumulation and the formation of large water droplets. At the same time, other dust and other foreign objects are not easily accumulated in the space between the second scraper 160 and the roller brush 130.

[0063] As previously mentioned, the roller brush 130 includes a base 131 and bristles 132. The base 131 is typically made of a hard material. The first scraper 150 and the second scraper 160 are prone to wear when they are in an interference fit with the hard material base 131. Furthermore, the friction between the first scraper 150 and the second scraper 160 and the hard material base 131 results in significant noise during the rotation of the roller brush 130 and may also increase the resistance to rotation. Therefore, in some embodiments, the free ends of the first scraper 150 and / or the second scraper 160 are in an interference fit with the bristles 132. Exemplarily, the free end of the second scraper 160 is tangent to the bristles 132, that is, tangent to the arcuate trajectory formed by the bristles 132 arranged circumferentially along the base 131.

[0064] Here, when the second scraper 160 is tangent to the outer side of the bristles 132, the interference fit between the second scraper 160 and the bristles 132 is small, which may prevent a good guiding effect on the cleaning liquid. Consequently, not only is it difficult to solve the aforementioned dripping problem, but it also cannot effectively clean the roller brush 130 and the surface 300 to be cleaned. Therefore, furthermore, in some embodiments, the free end of the second scraper 160 is approximately tangent to the middle section of the bristles 132. Specifically, please refer to... Figure 3 As shown, the radius of the base 131 is R1, the length of the bristles 132 in the radial direction of the base 131 is L1, and the distance from the free end of the second scraper 160 to the center of the base 131 is L2, where R1 < L2 < R1 + L1. Those skilled in the art will understand that, in order to achieve the technical objectives of the embodiments of this application, in embodiments where multiple layers of bristles 132 are provided on the roller brush 130, L1 here refers to the length of the outermost layer of bristles 132 in the radial direction of the base 131.

[0065] In some embodiments, to reduce the friction between the first scraper 150 and the second scraper 160, thereby reducing the resistance and noise during the operation of the roller brush 130, the first scraper 150 and the second scraper 160 may be made of a flexible material such as rubber. In some examples, bristles may also be provided at the free ends of the first scraper 150 and the second scraper 160. It is understood that in other embodiments, the first scraper 150 and the second scraper 160 may also be made of a rigid material, such as rigid plastic or metal.

[0066] During the rotation of the roller brush 130, taking the second scraper 160 as an example, the second scraper 160, which is interference-fitted with the roller brush 130, may bend. That is, a low point will be formed on the cross-section of the second scraper 160. The cleaning medium blocked by the second scraper 160 will flow to this low point, resulting in uneven distribution of the cleaning medium on the second scraper 160. This situation is more obvious when the first scraper 150 and the second scraper 160 are made of flexible materials. Therefore, in some embodiments, please refer to... Figures 6 to 7 The first scraper 150 and / or the second scraper 160 are comb-tooth assemblies; wherein, the comb-tooth assembly includes a body 171 extending along the axial direction of the roller brush 130 and a plurality of comb teeth 172 evenly spaced along the axial direction on the body 171, the free ends of the comb teeth 172 being interference-fitted with the roller brush 130. Here, a gap 173 is formed between every two adjacent comb teeth 172, and each gap 173 forms a space for accommodating cleaning media, so that the cleaning media blocked by the comb-tooth assembly can be more evenly distributed along the axial direction of the roller brush 130.

[0067] For example, please refer to Figure 6 The first scraper 150 is a comb assembly. As another example, please refer to... Figure 7 The second scraper 160 is a comb assembly. As another example, both the first scraper 150 and the second scraper 160 are comb assemblies.

[0068] To better achieve the technical effects of the embodiments of this application, the embodiments of this application also provide a floor brush assembly, which includes a roller brush cover 120, a roller brush 130, a spraying assembly 140, and a first scraper 150 and a second scraper 160 extending axially along the roller brush 130.

[0069] The roller brush cover 120 has a working side facing a surface 300 to be cleaned. Typically, the roller brush cover 120 is connected to a base 110 of a cleaning device 100. The roller brush cover 120 mates with the base 110 on the working side to form a roller brush cavity 111. Exemplarily, the working side is the side facing the surface 300 to be cleaned. The roller brush 130 is disposed on the roller brush cover 120 and located on the working side. The spray assembly 140 is disposed on the roller brush cover 120 and has a spray nozzle 141 located on the working side. The first scraper 150 and the second scraper 160 are both disposed on the working side, and their free ends are press-fitted with the roller brush 130.

[0070] When the floor brush assembly cleans the surface to be cleaned 300, the rotation direction of the roller brush 130 is the first direction, the spray nozzle 141, the first scraper 150 and the second scraper 160 are arranged sequentially in the first direction, and the contact position between the roller brush 130 and the first scraper 150 is located between the second scraper 160 and the spray nozzle 141 in the first direction.

[0071] In some embodiments, the free end of the second scraper 160 extends toward the roller brush 130 and is tangential to the roller brush 130.

[0072] In some embodiments, the roller brush 130 includes a base 131 and bristles 132 disposed on the base 131; the free end of the second scraper 160 is tangent to the bristles 132.

[0073] In some embodiments, the radius of the substrate 131 is R1; the length of the bristles 132 in the radial direction of the substrate 131 is L1; and the distance from the free end of the second scraper 160 to the center of the substrate 131 is L2; ​​wherein, R1 < L2 < R1 + L1.

[0074] In some embodiments, the roller brush 130 moves forward when cleaning the surface 300 to be cleaned, and the first scraper 150 and the second scraper 160 are both located on the front side of the roller brush 130, with the first scraper 150 located on the upper side of the second scraper 160.

[0075] In some embodiments, the first scraper 150 and / or the second scraper 160 are comb tooth assemblies; wherein the comb tooth assembly includes a body 171 extending along the axial direction of the roller brush 130 and a plurality of comb teeth 172 evenly spaced along the axial direction on the body 171, the free ends of the comb teeth 172 being interference-fitted with the roller brush 130.

[0076] In some embodiments, the roller brush 130 moves forward when cleaning the surface 300 to be cleaned, and the second scraper 160 is located on the front side of the roller brush 130, with a plurality of gaps 161 spaced apart on the second scraper 160.

[0077] It is understood that the meanings of the terms in the floor brush component of this embodiment are the same as those in the cleaning device 100 described above. For specific implementation details, please refer to the description in the embodiment of the cleaning device 100. The examples and technical effects shown in the foregoing embodiments can all be implemented by the floor brush component accordingly, and will not be repeated in this embodiment.

[0078] Application Example 1

[0079] In application example one, a cleaning device 100 is provided. This cleaning device 100 is a floor cleaning device, comprising a base 110, a roller brush cover 120, a roller brush 130, a spray assembly 140, a first scraper 150, and a second scraper 160. Here, the spray nozzle 141, the first scraper 150, and the second scraper 160 are arranged sequentially in the first direction, and the contact position between the roller brush 130 and the first scraper 150 is located between the second scraper 160 and the spray nozzle 141 in the first direction. During use, droplets falling outward from the position of the first scraper 150 are guided by the second scraper 160 to the roller brush 130 and will not fall onto the surface 300 to be cleaned, thus preventing significant dripping. Furthermore, compared to a single first scraper 150, the arrangement of the second scraper 160 allows for a more uniform distribution of the cleaning medium on the roller brush 130, while also improving the utilization rate of the cleaning medium and reducing losses due to dripping. As more cleaning medium adheres to the roller brush 130, the droplets at the first scraper 150 and the second scraper 160 are reduced, and the number of droplets falling is also reduced when the roller brush 130 stops rotating or the cleaning device 100 is pulled back.

[0081] In application example two, the structure of the cleaning device 100 is largely the same as in application example one, except that the first scraper 150 and the second scraper 160 are both located in front of the roller brush 130, and the first scraper 150 is located above the second scraper 160. Here, water droplets formed at the first scraper 150, when dripping downwards due to gravity, will drip onto the second scraper 160 below it, instead of dripping directly onto the surface 300 to be cleaned. Guided by the second scraper 160, these droplets can re-adhere to the roller brush 130, thereby reducing dripping and improving the utilization rate of the cleaning solution.

[0082] Application Example 3

[0083] In application example three, the structure of the cleaning device 100 is roughly the same as that in application example two. The difference is that the second scraper 160 is provided with a number of gaps 161 at intervals. The gaps 161 can improve the deformation capability of the second scraper 160 so that the second scraper 160 can be lifted more easily when it encounters dust particles, so that the dust particles will not be blocked on the front side of the second scraper 160 and can enter the roller brush cavity 111.

[0084] Application Example 4

[0085] In application example four, the structure of the cleaning device 100 is largely the same as that in application example one, except that the free end of the second scraper 160 is tangent to the middle section of the bristles 132. This arrangement ensures that the second scraper 160 does not create too much resistance to the operation of the roller brush 130, helps reduce noise, and also ensures good guidance of the cleaning medium.

[0086] Application Example 5

[0087] In application example five, the structure of the cleaning device 100 is roughly the same as that in application example one. The difference is that, here, the first scraper 150 and the second scraper 160 are both comb-tooth assemblies, and the cleaning medium blocked by the comb-tooth assemblies can be evenly distributed along the axial direction.

[0088] Application Example Six

[0089] In application example six, a roller brush cover 120 is provided, on which a spraying component 140, a roller brush 130, a first scraper 150 and a second scraper 160 as described in any of application examples one to five are provided.
