Description

Technical Field

[0001] This application relates to the field of household appliances, and in particular to a floor brush assembly for a vacuum cleaner and a vacuum cleaner. Background Technology

[0002] Currently, with the booming construction industry, people's living environments are filled with various types of dust. Furthermore, the Chinese people have a habit of opening windows for ventilation, resulting in a large amount of dust settling into rooms, living rooms, and other areas. If liquids are spilled on the floor, they can quickly solidify into grime, which is difficult to clean with regular vacuum cleaner brushes. Similarly, if liquids like cola or soy sauce are spilled on the floor and not cleaned quickly, the sugar in the liquid will adhere to the surface, making it difficult to clean with conventional vacuum cleaner brushes and requiring manual cleaning with a damp mop.

[0003] Existing vacuum cleaners mainly have two types of brush heads—dry brush heads and wet brush heads. Dry brush heads only have air ducts and some auxiliary dust removal devices (such as roller brushes, brush strips, etc.) inside, and clean the floor by suction and brushing. However, they are difficult to clean floating dust or solidified viscous liquids stuck to the floor. Wet brush heads have an external water tank and mop, which can vacuum and mop the floor. However, wet brush heads are large and bulky, and filling the water tank requires additional devices and actions. The products are complex and unreliable, which greatly reduces the user experience.

[0043] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0044] The following is for reference. Figures 1-9 This application describes a floor brush assembly 100 for a vacuum cleaner and a vacuum cleaner according to embodiments thereof.

[0045] like Figure 1 and Figure 2 As shown, the floor brush assembly 100 according to an embodiment of this application includes: a brush head body 110 and a cleaning structure 120. The brush head body 110 is provided with a suction port 101. Under the action of the driving component, the vacuum cleaner can generate negative pressure at the suction port 101, allowing floating dust or debris on the floor to enter the dust cup of the vacuum cleaner through the suction port 101.

[0046] The floor brush assembly 100 of this application also includes a cleaning structure 120 disposed on the brush head body 110. The cleaning structure 120 is configured to selectively absorb water to clean stubborn stains on the floor. That is, at least a portion of the cleaning structure 120 can be configured as a water-absorbing element, thereby absorbing water and keeping it moist, thereby cleaning stubborn stains on the floor, such as hardened solid dirt.

[0047] According to the embodiments of this application, the floor brush assembly 100 is configured to selectively absorb water by at least a portion of the cleaning structure 120, so that it can both absorb easily cleanable floating dust or debris and clean stubborn stains on the floor. Therefore, the floor brush assembly 100 in this application is a hybrid floor brush. Thus, the vacuum cleaner only needs to be equipped with this type of floor brush assembly 100 to perform all-round cleaning of the floor, which is more efficient and provides a better user experience.

[0048] In some embodiments of this application, the cleaning structure 120 is detachably mounted on the brush head body 110. Therefore, after the cleaning structure 120 has cleaned stubborn stains on the floor, it can be easily detached from the brush head body 110 for further cleaning, facilitating the cleaning structure 120 to clean the floor again.

[0049] According to some embodiments of this application, such as Figure 3-9 As shown, the cleaning structure 120 includes a water-absorbing element 121, which is movably mounted on the brush head body 110. The water-absorbing element 121 can absorb water, thereby keeping the water-absorbing element 121 moist for easy cleaning of stubborn stains on the floor. It is understood that the water-absorbing element 121 can also absorb water containing cleaning agent.

[0050] Since the water-absorbing component 121 is movably mounted on the brush head body 110, after cleaning stubborn stains on the ground from one part of the water-absorbing component 121, it can be switched to other clean parts, thereby improving the efficiency of the water-absorbing component 121 and enhancing the user experience.

[0051] Furthermore, the absorbent element 121 is rotatably mounted on the brush head body 110. Therefore, after cleaning stains from a portion of the outer peripheral surface of the absorbent element 121, the user can switch to other portions of the outer peripheral surface of the absorbent element 121, thereby greatly improving the efficiency of the absorbent element 121.

[0052] Furthermore, the water-absorbing element 121 is rotatably mounted on the brush head body 110. Thus, when the water-absorbing element 121 needs to remove stubborn stains on the floor, its rotation can be restricted; when it is necessary to switch the position of the water-absorbing element 121 in removing stains, the floor brush assembly 100 can be moved in the direction in which the water-absorbing element 121 can rotate unidirectionally.

[0053] Furthermore, the absorbent component 121 is configured to rotate unidirectionally when the brush head body 110 is dragged backward. That is, the absorbent component 121 only rotates when the brush head body 110 is dragged backward; it does not rotate when the brush head body 110 is dragged forward. This ensures that the brush head body 110 can absorb dust smoothly on the ground when there are no stubborn stains, unaffected by the rotation of the absorbent component 121. Simultaneously, it ensures that when stubborn stains need to be cleaned, the absorbent component 121 rotates to improve its efficiency.

[0054] In some embodiments of this application, the cleaning structure 120 further includes a water tank 122 adapted to supply water to the water-absorbing member 121, at least a portion of which is disposed inside the water-absorbing member 121. Thus, without disassembling the entire cleaning structure 120 for water absorption and cleaning, the water tank 122 can continuously supply water to the water-absorbing member 121 to meet its humidification requirements.

[0055] Furthermore, the water tank 122 is mounted on the brush head body 110, and the water suction component 121 is rotatably mounted on the water tank 122. In other words, the water tank 122 can be hidden inside the water suction component 121, and the user will not see the water tank 122 directly from the outside, so that the overall aesthetics of the floor brush assembly 100 will not be affected by the external placement of the water tank 122.

[0056] Specifically, the water tank 122 includes a water storage section 122a and a water supply section 122b connected to the water storage section 122a, wherein the water supply section 122b is disposed inside the water suction member 121. The water suction member 121 is sleeved on the water supply section 122b and is rotatable relative to the water supply section 122b. The water supply section 122b can extend along the length direction of the brush head body 110, and the water storage section 122a is disposed at one end of the water supply section 122b in the length direction. Thus, the water supply section 122b can penetrate the water suction member 121, facilitating better water supply to the water suction member 121.

[0057] The water supply section 122b is provided with a water supply hole that communicates with the space inside the water supply section 122b. It should be noted that both the water supply section 122b and the water storage section 122a are provided with a space to hold water. The water in the space can flow out through the water supply hole and be absorbed by the water absorption member 121 sleeved on the outside of the water supply section 122b, so that the water absorption member 121 is kept moist.

[0058] According to some embodiments of this application, a one-way locking mechanism 130 is provided between the water-absorbing member 121 and the water storage section 122a, which is suitable for causing the water-absorbing member 121 to rotate in one direction. The one-way locking mechanism 130 allows the water-absorbing member 121 to rotate in one direction, ensuring that the water-absorbing member 121 rotates in one direction when rotation is required, and that the water-absorbing member 121's cleaning effect is not affected by continuous rotation.

[0059] Specifically, the one-way locking mechanism 130 includes a rolling locking block 131 and engaging teeth 132. The rolling locking block 131 is rotatably mounted on the water storage section 122a, and the engaging teeth 132 are mounted on the water suction member 121 and are adapted to selectively engage with the rolling locking block 131. When the engaging teeth 132 engage with the rolling locking block 131 and tend to move the rolling locking block 131 in a rotatable direction, the water suction member 121 can rotate without restriction; when the engaging teeth 132 engage with the rolling locking block 131 and tend to move the rolling locking block 131 in a non-rotatable direction, the water suction member 121 is restricted and cannot rotate.

[0060] More specifically, the rolling locking block 131 includes a stop portion 131a and a mating portion 131b connected to the stop portion 131a, the mating portion 131b selectively engaging with the meshing teeth 132. The water storage portion 122a is provided with a baffle 122c that normally abuts against the lower side of the stop portion 131a, and a clearance space 102 provided on the upper side of the baffle 122c to allow the stop portion 131a to rotate. That is, when the stop portion 131a moves downwards, it is restricted by the baffle 122c; only when the stop portion 131a moves upwards can it move freely within the clearance space 102. Therefore, the stop portion 131a can only rotate upwards and not downwards. Consequently, the water-absorbing member 121, which meshes with the rolling locking block 131, can only rotate when the brush head body is dragged backwards; the water-absorbing member 121 does not rotate when the brush head body 110 is dragged forwards.

[0061] In some embodiments of this application, an elastic member 133 is provided in the clearance space 102 to press the stop portion 131a against the baffle 122c. That is, to enable the water-absorbing member 121 to rotate, it is necessary to overcome the elastic force applied to the stop portion 131a by the elastic member 133. When the external force disappears, the stop portion 131a is pressed against the baffle 122c by the elastic force of the elastic member 133.

[0062] The absorbent component 121 includes an absorbent component mounting portion 121a and an absorbent component body 121b disposed on the absorbent component mounting portion 121a. The absorbent component mounting portion 121a is provided with engaging teeth 132. The absorbent component mounting portion 121a can be a mounting base, and the absorbent component body 121b can be made of a material that easily absorbs water, such as a sponge.

[0063] The water-absorbing body 121b is sleeved on the water-absorbing mounting part 121a, and the water-absorbing mounting part 121a is provided with a through hole communicating with the water supply hole.

[0064] In some embodiments of this application, the absorbent 121 further includes a filter structure adapted to drain the water on the absorbent 121. The filter structure can squeeze the water off the absorbent 121 when there is too much water adsorbed on the absorbent 121 or when the absorbent 121 needs to be cleaned.

[0065] The water filtration structure can be constructed as a filter plate 123, which can be annular and optionally fitted onto the outer peripheral wall of the water-absorbing member 121. Thus, by moving the filter plate 123, the water-absorbing member body 121b can be squeezed, thereby squeezing out the water on the water-absorbing member body 121b.

[0066] To facilitate the movement of the filter plate 123, a foldable filter plate handle 124 can be provided on the filter plate 123. When it is necessary to move the filter plate 123, the filter plate handle 124 can be folded to the unfolded position, and the filter plate 123 can be pulled to squeeze out the water in the water suction member 121. When it is not necessary to move the filter plate 123, the filter plate handle 124 can be folded to the storage position to avoid the filter plate handle 124 taking up space or affecting the rotation of the water suction member 121.

[0067] In some embodiments of this application, the brush head body 110 is provided with an air duct 103 communicating with the suction port 101. Dust drawn in from the suction port 101 can enter the dust bag of the vacuum cleaner through the air duct 103. Optionally, there are multiple air ducts 103, and all of the multiple air ducts 103 are communicating with the suction port 101. Thus, the dust collection efficiency of the floor brush assembly 100 is effectively improved.

[0068] Furthermore, the suction port 101 is located in front of the cleaning structure 120, and at least a portion of the air duct 103 is located on the front and upper sides of the cleaning structure 120. Thus, the suction port 101 can first suck away the floating dust on the ground, and then the cleaning structure 120 can clean the stubborn stains on the ground.

[0069] The brush head body 110 includes a brush head cover 111 and a brush head lower cover 112, which are detachably connected and define a suction port 101 and an air duct 103. The brush head lower cover 112 includes a front section 112a, a middle section 112b, and a rear section 112c connected in sequence. The front section 112a and the front end of the brush head cover 111 define the suction port 101. The middle section 112b and the rear section 112c and the brush head cover 111 define the air duct 103. The middle section 112b is constructed as an arc-shaped surface and protrudes upward to define a space for accommodating the water suction component 121.

[0070] Specifically, an air duct cover 111a is provided on the inner side of the brush head cover 111, and the air duct cover 111a and the brush head lower cover 112 define the air duct 103.

[0071] In some embodiments of this application, the middle section 112b is at least constructed as a transparent element to form a transparent window. This allows consumers to clearly observe the interior of the air duct 103, while also giving the floor brush assembly 100 a more technological feel.

[0072] In some embodiments of this application, the floor brush assembly 100 further includes a connector assembly 140 connected to the air duct 103. Dust and debris entering from the suction port 101 can enter the connector assembly 140 from the air duct 103, and then enter the dust bag of the vacuum cleaner from the connector assembly 140.

[0073] The following is a brief description of the vacuum cleaner according to an embodiment of this application.

Since the floor brush assembly 100 is provided according to the embodiments of this application, the vacuum cleaner can more conveniently remove stubborn stains on the floor. Moreover, the rotation direction of the water suction component 121 is unidirectional, which ensures that the vacuum cleaner has more diverse functions without affecting the cleaning efficiency of the vacuum cleaner.
