Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a floor brush structure for a cleaning equipment with functional zones. Background Technology

[0002] In the technological development of cleaning equipment (especially floor cleaning tools such as vacuum cleaners and robot vacuums), the floor brush, as a core component that comes into direct contact with the cleaning surface, directly affects cleaning efficiency, ease of use, and user experience through its structural design.

[0003] Existing floor brush structures generally suffer from the following technical problems in their collaborative working mechanism of dust generation and suction: (1) The dust-raising function and the suction port are usually integrated in the same functional area, which makes it difficult to ensure the airtightness of the area. The airflow generated during the dust-raising process and the negative pressure generated by the suction interfere with each other, and some dust may overflow due to poor sealing, reducing cleaning efficiency; (2) If the floor brush is only set with a single suction port function area, the suction port will be strongly adhered to soft surfaces such as carpets due to negative pressure during operation, resulting in excessive resistance to pushing the floor brush and affecting the user experience.

[0004] In summary, the existing floor brush structure, due to the lack of proper separation between the dust-generating and suction functional areas and the difficulty in balancing sealing and propulsion performance, has become a key bottleneck restricting the development of cleaning equipment towards higher efficiency and greater convenience. Therefore, there is an urgent need for a floor brush structure design that can achieve independent operation of the dust-generating and suction areas while balancing sealing performance and ease of operation. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a floor brush structure for a cleaning device with functional zones, so as to achieve physical isolation between dust raising and dust suction functions, improve the airtightness of the area, and give the dust raising area an auxiliary pushing function, thereby reducing the adhesion between the floor brush and the cleaning surface.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A functionally partitioned cleaning equipment floor brush structure includes a floor brush body. The bottom of the floor brush body is provided with a dust-raising area and a dust-suction area, which are independent of each other. The dust-raising area can reduce the pushing resistance of the floor brush on the cleaning surface. The dust-raising area is provided with at least one dust-raising component for dust-raising operation and sealing of the cleaning surface. The dust-suction area is provided with an air duct suction port for suctioning the dirt after dust-raising.

[0007] Optionally, the dust-generating component includes a bristle roller rotatably mounted on the bottom of the floor brush body, the bristle roller being in contact with the cleaning surface.

[0008] Optionally, the dust-generating component includes a scraper blade installed on the bottom surface of the floor brush body, and the scraper blade is in contact with the cleaning surface.

[0009] Optionally, the dust-generating area is provided with a fluff roller and a scraper, and the fluff roller and the scraper are distributed on the front and rear sides of the air duct inlet.

[0010] Optionally, the dust-generating area and the dust-collecting area are spatially separated.

[0011] Optionally, the dust-generating component forms a closed, sealed area when it comes into contact with the clean surface, and the sealed area can confine the dust within the dust-generating area.

[0012] Optionally, the dust-generating component generates a supporting force when it comes into contact with the clean surface, and the supporting force can counteract the adsorption force generated by the negative pressure in the dust-collecting area.

[0013] Optionally, the cleaning device is a vacuum cleaner, and the floor brush structure is connected to the main unit air duct of the vacuum cleaner through the air duct suction port.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) In this utility model, by separating the dust-raising area and the dust-collecting area independently, airflow interference can be avoided. The sealing effect of the dust-raising component can confine the dust within the dust-raising area, ensuring that the negative pressure of the dust-collecting area efficiently adsorbs dirt and reduces dust overflow. Furthermore, this device can be realized simply through functional zoning and component optimization, without the need for a complex drive structure, which is convenient for industrial production. (2) In this utility model, the pile roller or scraper in the dust area provides support when it comes into contact with the cleaning surface, which can offset part of the adsorption force, solve the problem that traditional floor brushes are difficult to push on carpets, and improve the user experience.

[0015] Figure 1 This is a bottom view of the floor brush structure of the cleaning equipment with functional zones in an embodiment of this utility model; Figure 2 This is a schematic diagram of the internal structure of the floor brush structure of the cleaning equipment with functional zones in an embodiment of this utility model; The components include: 1. Floor brush body; 2. Dust-generating area; 201. Fluff roller; 202. Scraper strip; 3. Dust-collecting area; 301. Air duct inlet; 4. Main unit air duct; 5. Mounting slot; 6. Partition. Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0017] Example 1, as Figure 1 and Figure 2 As shown, a floor brush structure for a functionally partitioned cleaning device includes a floor brush body 1. The bottom of the floor brush body 1 is provided with a dust-raising area 2 and a dust-suction area 3, which are independent of each other. The dust-raising area 2 is provided with at least one dust-raising component, and the dust-suction area 3 is provided with an air duct suction port 301. The dust-raising component is used to perform dust-raising operations on the cleaning surface and to achieve sealing, while the air duct suction port 301 is used to suction the dirt after dust raising. The dust-raising area 2 also has an auxiliary pushing function to reduce the pushing resistance of the floor brush on the cleaning surface.

[0018] Traditional floor brushes often integrate dust-raising components (such as the brush roller 201 and scraper 202) with the suction port in the same functional area, sharing an open or semi-enclosed space. In this design, the airflow (containing suspended dust) generated during dust raising and the negative pressure airflow generated by the suction port can interfere with each other: on the one hand, the turbulence during dust raising may disrupt the stability of the negative pressure at the suction port, causing some dust to overflow without being effectively sucked in; on the other hand, the negative pressure at the suction port may directly affect the dust-raising components, causing structures such as the brush roller 201 to reduce their dust-raising effectiveness due to airflow impact (e.g., dust adsorbed by the brush roller 201 is sucked away prematurely, failing to adequately raise deep-seated dirt).

[0019] This invention separates the dust-generating area 2 from the dust-collecting area 3, thus avoiding airflow interference. The sealing effect of the dust-generating component can confine the dust within the dust-generating area 2, ensuring that the negative pressure of the dust-collecting area 3 efficiently adsorbs dirt and reduces dust overflow. Furthermore, this device can be achieved simply through functional zoning and component optimization, without the need for a complex drive structure, making it easy for industrial production.

[0020] Specifically, the cleaning equipment mentioned here includes, but is not limited to, vacuum cleaners and robotic vacuum cleaners; taking a vacuum cleaner as an example, the floor brush structure is connected to the vacuum cleaner's main unit air duct 4 through the air duct suction port 301. After the dust-raising component performs dust-raising operations on the cleaning surface, negative pressure is generated in the main unit air duct 4 under the action of the vacuum cleaner's main unit (vacuum motor). The main unit air duct 4 is connected to the air duct suction port 301, thereby efficiently adsorbing dirt.

[0021] As mentioned above, since the dust-raising and suction areas 3 of traditional floor brushes are not physically separated, the sealing design cannot meet the needs of both. If the seal is too tight, it will hinder the movement of the dust-raising components (such as the roller brush being obstructed from rotating); if the seal is too loose, the suction efficiency will be greatly reduced, ultimately resulting in a compromised cleaning effect.

[0022] Based on this, the dust collection area 3 and the dust raising area 2 at the bottom of the main body of the floor brush of this utility model are independent of each other, and the two are spatially separated. During operation, the airflow of the two is not connected. When the dust raising component comes into contact with the cleaning surface, it forms a closed sealing area. Due to the sealing effect, the sealing area can confine the dust within the dust raising area 2 to reduce dust overflow. That is, after the dust raising component in the dust raising area 2 raises the dirt on the cleaning surface, under the action of negative pressure in the main unit air duct 4, the dirt passes through the air duct suction port 301 of the dust collection area 3 and enters the main unit air duct 4, and enters the corresponding dust cup for storage along the main unit air duct 4.

[0023] Traditional floor brushes, in pursuit of high suction efficiency, feature only a single suction port, relying on strong negative pressure to directly adsorb surface dirt. While this design works fine on hard surfaces (such as tile and wood flooring), it presents serious drawbacks on soft surfaces like carpets and mats. The strong negative pressure at the suction port causes the brush edge to adhere tightly to the carpet fibers, even locally lifting the carpet, resulting in a dramatic increase in friction between the brush and the surface. Users must exert extra force to overcome this suction resistance, increasing operator fatigue and potentially causing uneven force to deviate from the cleaning path, affecting cleaning coverage. Over time, this strong suction can also damage carpet fibers (such as causing pilling), reducing the lifespan of the cleaned surface.

[0024] Based on this, the floor brush structure proposed in this utility model also provides an auxiliary pushing function to the dust-raising area 2; the auxiliary pushing function of the dust-raising area 2 is achieved by the supporting force generated when the dust-raising component comes into contact with the cleaning surface. This supporting force can counteract the suction force generated by the negative pressure in the suction area 3, thus preventing the floor brush from being strongly adhered to the cleaning surface.

[0025] When the dust-generating components in dust-generating zone 2 come into contact with the cleaning surface, they generate an upward supporting force. Especially on soft surfaces such as carpets, the elastic deformation of the pile roller 201 provides continuous support. This supporting force directly counteracts the downward suction force generated by the negative pressure in vacuuming zone 3, thus balancing the pressure between the floor brush and the cleaning surface.

[0026] In Example 2, based on Example 1, the dust-generating component uses a fluff roller 201. The fluff roller 201 generates dust by rolling and contacting the cleaning surface, and achieves sealing by adhering to the cleaning surface. The fluff roller 201 is rotatably mounted on the bottom of the brush body 1 and is driven to rotate by a motor inside the brush body 1 through a transmission structure. The axis of the fluff roller 201 is generally parallel to the cleaning surface, and the lower part of the circumferential surface of the fluff roller 201 passes through the bottom surface of the brush body 1 and adheres to the cleaning surface.

[0027] The lint roller 201 and the air duct suction port 301 are divided into two independent functional areas. The lint roller 201 is used to perform dust removal and sealing on the cleaned surface, while the air duct suction port 301 is used to vacuum the dirt after it has been removed by the lint roller 201.

[0028] Specifically, the bottom of the floor brush body 1 is provided with a mounting groove 5, in which a bristle roller 201 is rotatably mounted. The lower part of the bristle roller 201 extends outward through the opening end face of the mounting groove 5 and fits against the cleaning surface. A partition 6 is provided between the mounting groove 5 and the air duct suction port 301, and the upper part of the partition 6 is connected to the floor brush housing. At this time, the bristle roller 201 and the air duct suction port 301 are located in two independent semi-enclosed spaces.

[0029] In Example 3, based on Example 1, the dust-raising component uses scraper blades 202. Multiple scraper blades 202 are provided, spaced apart on the bottom surface of the brush body 1, and each scraper blade 202 can contact the cleaning surface. The scraper blades 202 are made of rigid or semi-rigid materials (such as wear-resistant rubber or engineering plastics). During operation, the scraper blades 202 maintain close contact with the cleaning surface (such as the floor or carpet). Through the relative movement during the brush's pushing process, they scrape and peel off stubborn dirt adhering to the surface (such as dried liquid residue, adhered particles, and dust embedded in the carpet fibers), forcibly lifting it from the cleaning surface.

[0030] When the scraper 202 comes into contact with the cleaning surface, it generates an upward supporting force. Especially on soft surfaces such as carpets, this supporting force can counteract the suction force generated by the negative pressure in the vacuuming area 3, reducing the pressure of the floor brush against the surface.

[0031] In addition, if the scraper 202 is made of a low-friction coefficient material (such as modified rubber), its smooth edge design can reduce the sliding resistance with the surface, further assisting the brush to move smoothly.

[0032] Example 4, as Figure 1 and Figure 2 As shown, based on Embodiments 1 to 3, the dust-generating area 2 is provided with both a fluff roller 201 and a scraper 202, and the fluff roller 201 and the scraper 202 are distributed on the front and rear sides of the air duct suction port 301. That is, the dust-generating component uses both the fluff roller 201 and the scraper 202, and the two cooperate with each other.

[0033] The edge of the scraper 202 fits tightly against the cleaning surface, complementing the flexible seal of the pile roller 201. The pile roller 201 achieves a large-area flexible seal through the elastic deformation of the pile, while the scraper 202, with its rigid edge linear contact, performs a secondary seal on the edge gaps of the dust-raising area 2, together constructing a closed dust-raising space to prevent the dust from overflowing from the gaps.

[0034] When the fluff roller 201 (elastic support) and scraper 202 (rigid contact) of the dust-generating area 2 come into contact with the cleaning surface, they generate an upward supporting force. This supporting force can counteract the downward suction force generated by the negative pressure in the vacuuming area 3, balance the pressure between the floor brush and the cleaning surface, and prevent the floor brush from being difficult to move on soft surfaces such as carpets due to strong suction, thus achieving a drag-reducing effect while cleaning.

[0035] The fluff of the fluff roller 201 is flexibly attached to the cleaning surface, and the edge of the scraper 202 is in close contact with the surface. Together, they form a double seal in the dust-raising area 2, confining the raised dirt within the enclosed space. This ensures that the negative pressure of the suction area 3 can be concentrated on this area, reducing dust overflow, and at the same time preventing the dust-raising airflow and the suction airflow from interfering with each other.

[0036] This invention features a functional partition design at the bottom of the floor brush, which physically isolates and coordinates the dust-raising and vacuuming processes. Its working principle is as follows: Dust-generating area 2 is equipped with a pile roller 201 and a scraper 202. Both are in direct contact with the cleaning surface (floor, carpet, etc.) and use rolling friction (pile roller 201) and edge scraping (scraper 202) to lift the attached dirt (dust, hair, particles, etc.) from the surface. At the same time, the structure itself (pile adhering and scraper 202 edge sealing) forms a closed space to prevent dust from overflowing. The dust collection area 3 is equipped with an independent air duct suction port 301, which is connected to the negative pressure system of the cleaning equipment host. The negative pressure sucks in and collects the dirt raised in the dust area 2. Because it is physically isolated from the dust area 2, airflow interference is avoided, ensuring stable and efficient negative pressure. During operation, the dust-raising zone 2 first uses the lint roller 201 and scraper 202 to peel off and lift deep or stubborn dirt from the cleaning surface, keeping the dirt in a suspended state. Then, the adjacent dust-collecting zone 3 uses the negative pressure generated by the air duct suction port 301 to accurately capture these suspended dirt, forming a continuous process of lifting and then suction, which improves cleaning efficiency.

[0037] In summary, this utility model discloses a functionally partitioned floor brush structure for cleaning equipment. Its core features are an independent dust-raising area 2 and a suction area 3 at the bottom of the brush. The dust-raising area 2 achieves dust raising and sealing through a bristle roller 201 and a scraper 202, while the suction area 3 uses negative pressure suction through an air duct inlet 301. Simultaneously, the components of the dust-raising area 2 have an auxiliary pushing function to counteract the suction force. This utility model solves the problems of poor airtightness, inadequate cleaning effect, and difficulty in pushing existing floor brushes. It is suitable for vacuum cleaners and other equipment, and has the advantages of simple structure and convenient use.
