Description

Technical Field

[0001] This disclosure relates to a floor brush assembly and surface cleaning equipment. Background Technology

[0002] A floor scrubber is a cleaning device suitable for home use, primarily used for cleaning and washing household floor surfaces.

[0003] Floor scrubbers automatically spray water and scrub the floor, then suck the wastewater and residual dirt into the machine's wastewater tank. Floor scrubbers are easy to use and provide a thorough cleaning. However, when cleaning the surface, some water residue remains behind the roller brush. Current technology typically removes this residue with a squeegee. Because the relative speed between the squeegee and the surface is low, the squeegee generally lacks cleaning effectiveness. Consequently, when dealing with stubborn stains, floor scrubbers are inefficient, time-consuming, and result in a significantly poor user experience. Utility Model Content

Detailed Implementation

[0023] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0024] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0026] Figure 1 This is a schematic diagram of the structure of a surface cleaning device according to one embodiment of the present disclosure.

[0027] The surface cleaning apparatus disclosed herein is configured to perform wet cleaning of a surface to be cleaned, wherein the surface to be cleaned may be a floor surface, preferably a household floor surface. Furthermore, after the surface cleaning apparatus performs wet cleaning of the floor surface, the dirt and liquid (wastewater) remaining from cleaning the surface can be recycled back to the surface cleaning apparatus.

[0028] The surface cleaning device disclosed herein may include an upright body. Specifically, the upright body of the present disclosure may include a handle portion 100 and a main body portion 200. The handle portion 100 is detachably disposed on the main body portion 200. The user can operate the surface cleaning device by operating the handle portion 100, and the upright body can work in a manner substantially parallel to the surface to be cleaned during the operation of the surface cleaning device.

[0029] The handle 100 may be equipped with a user interaction button, which allows the user to control the surface cleaning equipment by triggering the button, such as controlling the start and stop of the surface cleaning equipment, as well as controlling the liquid supply speed and suction power of the suction source.

[0030] The main body 200 is pivotally connected to the floor brush assembly 600 via the connecting part 500; thus, when the user operates the handle part 100, the floor brush assembly 600 can be moved on the surface to be cleaned, and the surface to be cleaned can be cleaned by the floor brush assembly 600.

[0031] In one example, the connection 500 may include a universal joint to allow the main body 200 to rotate relative to the floor brush assembly 600 in two directions. In another example, the connection 500 may include a multi-axis joint that couples the main body 200 to the floor brush assembly 600 to allow the main body 200 to rotate relative to the floor brush assembly 600 along a first direction and a second direction.

[0032] The main body 200 can be pivoted to an upright position (also known as a storage position) via the connecting part 500. In this position, the angle between the main body 200 and the surface of the floor brush assembly 600 (or the ground) is 80° to 90°, preferably around 80°. In this position, the surface cleaning device is in a self-supporting posture (also known as an upright posture), meaning that the main body 200 and the like can be supported by the floor brush assembly 600, and an upright posture can be achieved without the aid of other objects.

[0033] The main body 200 can also accommodate components such as the liquid supply tank assembly 300 and the recovery tank container 400. In this disclosure, the liquid supply tank assembly 300 is detachably mounted to the side of the main body 200, and the mounting position can be located on the front side of the main body 200. The recovery tank container 400 is detachably mounted to the side of the main body 200, and the mounting position can be located on the rear side of the main body. In another embodiment, the liquid supply tank assembly 300 of this disclosure can also be disposed on the floor brush assembly 600.

[0034] In one example, the thickness of the recycling tank container 400 is set to be less than its width, and the height of the liquid supply tank assembly 300 is set to be less than its width. This ensures sufficient capacity and allows the overall height of the surface cleaning equipment to be less than a predetermined height, such as 120mm, after the main body 200 is laid flat.

[0035] The liquid supply tank assembly 300 is used to store the cleaning liquid to be dispensed. Accordingly, the liquid supply tank assembly 300 can be connected and fluidly communicated with a fluid dispenser (not shown in the figure), so that the cleaning liquid in the liquid supply tank assembly 300 can be pressurized by the fluid dispenser and supplied to the floor brush assembly 600, or to the surface to be cleaned near the floor brush assembly 600, thereby enabling wet cleaning of the surface to be cleaned by the cleaning liquid.

[0036] In one example, the fluid dispenser may include a supply pump capable of drawing cleaning liquid from the supply tank assembly 300, pressurizing the cleaning liquid, and supplying it to the outlet component, which then supplies the pressurized cleaning liquid to the roller brush component 610 of the floor brush assembly 600 or to the surface to be cleaned near the roller brush component 610.

[0037] In this disclosure, the cleaning liquid can be one or more of any suitable liquid, including but not limited to cleaning water, concentrated detergent, diluted detergent, or mixtures thereof. Furthermore, the cleaning liquid can be a room-temperature cleaning liquid or a high-temperature cleaning liquid.

[0038] The main body 200 has a receiving space. The recycling tank container 400 is detachably installed in the main body 200 and located in the receiving space. When the recycling tank container 400 contains a large amount of liquid, the user can remove the recycling tank container 400, pour out the sewage inside, and clean up the solid waste. At this time, part of the outer surface of the recycling tank container 400 forms part of the outer surface of the surface cleaning device.

[0039] Figure 2 This is a schematic diagram of the structure of a floor brush assembly of a surface cleaning device according to one embodiment of the present disclosure. Figure 3 This is a structural schematic diagram of the floor brush assembly of a surface cleaning device according to one embodiment of the present disclosure from another angle. Figure 4 This is a partial structural schematic diagram of the floor brush assembly of a surface cleaning device according to one embodiment of the present disclosure. Figure 5 This is a schematic diagram of the suction port of the floor brush assembly of a surface cleaning device according to one embodiment of the present disclosure. Figure 6 This is a schematic diagram of the scraping roller of the floor brush assembly of a surface cleaning device according to one embodiment of the present disclosure.

[0040] like Figures 1 to 6 As shown, the floor brush assembly 600 of this disclosure may include components such as a roller brush component 610, a housing portion 620, a scraping roller 630, and a drive mechanism 640.

[0041] The housing portion 620 has a receiving space; specifically, the receiving space is formed at the front end of the housing portion 620. In a specific embodiment, the housing portion 620 may include a receiving shell and a cover portion, the cover portion being disposed above the receiving shell, and the receiving shell and the cover portion being fixed together to form the housing portion 620.

[0042] The roller brush component 610 is rotatably disposed in the housing portion 620 and located within the receiving space, wherein the roller brush component 610 is configured to rotate about a first rotation axis; the axial direction of the first rotation axis is the longitudinal direction of the surface cleaning device.

[0043] The roller brush component 610 can be implemented using existing roller brush components, and its structure will not be described in detail in this disclosure.

[0044] The scraping roller 630 is mounted behind the roller brush component 610. The scraping roller 630 is configured to have a second rotation axis parallel to the first rotation axis of the roller brush component 610. That is, the scraping roller 630 of this disclosure can also be driven to rotate. As a result, the scraping roller 630 of this disclosure can make pressure contact with the surface to be cleaned. Due to the rotation of the scraping roller 630, there is a large relative speed between the scraping roller 630 and the surface to be cleaned. Therefore, the scraping roller 630 can not only scrape off water stains, but also play an auxiliary role in cleaning. Accordingly, the cleaning ability and cleaning efficiency of the surface cleaning equipment of this disclosure are improved.

[0045] The upper region of the scraping roller 630 is not exposed to the receiving space; specifically, a receiving space 621 is formed on the lower surface of the front end of the receiving shell, within which the scraping roller 630 can be located. Furthermore, the front end of the receiving shell can interfere with the scraping roller 630, so that dirt on the scraping roller 630 can be transferred to the upper surface of the front end of the receiving shell and further enter the suction port 622.

[0046] In this disclosure, a suction opening leading to the receiving space is formed between the roller brush component 610 and the scraping roller 630; in other words, there is a gap between the roller brush component 610 and the scraping roller 630, which is the aforementioned suction opening. At this time, the roller brush component 610 and the scraping roller 630 do not interfere with each other and rotate independently, allowing gas to enter the receiving space through the suction opening and further flow to the suction port 622.

[0047] A drive mechanism 640 is operatively coupled to a scraping roller 630 to drive the scraping roller 630 to rotate. The drive mechanism 640 is configured such that the rotation direction of the scraping roller 630 is opposite to the rotation direction of the brush component 610. Figure 2 In the implementation shown, the roller brush component 610 rotates clockwise and the scraping roller 630 rotates counterclockwise. Thus, on the one hand, the scraping roller 630 can scrape away water stains on the ground, and on the other hand, the direction in which the scraping roller 630 rubs the dirt on the surface to be cleaned is opposite to that of the roller brush component 610, which improves the cleaning effect of the scraping roller 630 on stubborn stains.

[0048] In a preferred embodiment, the bottommost contact surface of the scraping roller 630 is located below the bottommost contact surface of the roller brush component 610; that is, when the floor brush assembly 600 of this disclosure is suspended, the bottommost point of the scraping roller 630 is lower than the bottommost point of the roller brush component 610. As a result, the scraping roller 630 can have a greater amount of interference with the surface to be cleaned, and correspondingly, the scraping roller 630 has a better effect on scraping water stains and cleaning the surface to be cleaned.

[0049] The outer side of the receiving shell forms part of the sidewall of the receiving space. Specifically, the front end of the receiving shell forms part of the sidewall of the receiving space, while the lower surface of the cover component forms another part of the sidewall of the receiving space.

[0050] The container shell has a suction port 622 located at the front end of the container shell and communicating with the container space. Thus, gas, liquid and / or dirt in the container space can enter the suction port 622 and be further collected into the recycling tank container.

[0051] In one embodiment, the scraping roller 630 includes a main shaft portion 631 and at least one scraper blade 632; the main shaft portion 631 has a longitudinal axis that coincides with a second rotation axis; the scraper blade 632 extends outward from the surface of the main shaft portion 631 along the longitudinal axis at a first angle. Thus, interference between the scraping roller 630 and the surface to be cleaned can be achieved by the deformation of the scraper blade 632.

[0052] In one embodiment, the first angle is 90°. That is, the length direction of the scraper 632 is the longitudinal axis of the main shaft portion 631, and the width direction of the scraper 632 is the radial direction of the main shaft portion 631. At this time, the scraper 632 is formed into a cuboid structure fixed to the main shaft portion 631, and its free end can interfere with the surface to be cleaned.

[0053] In this disclosure, the drive mechanism 640 includes a motor and a belt drive mechanism connected to the motor and one end of the scraping roller 630 to transmit the rotation of the motor to the scraping roller 630. Specifically, the motor can be disposed in the housing portion 620 and provide power, and the belt drive mechanism is used to transmit power to cause the scraping roller 630 to rotate.

[0054] More preferably, the belt drive mechanism of this disclosure includes a drive bracket 641, which is located on the drive end bracket of the roller brush component 610. Thus, a drive shaft is rotatably disposed on the drive bracket 641, and the scraping roller 630 can be sleeved on the drive shaft and driven and rotated by the drive shaft.

[0055] The blades of the scraping roller 630 disclosed herein are made of a soft rubber material, such as rubber or silicone. When the blades of the scraping roller 630 come into contact with the surface to be cleaned, the blades can deform, thereby facilitating the removal of water stains and cleaning of the surface to be cleaned.

[0056] The roller brush component 610 of this disclosure can be driven by the same motor as the scraping roller 630, or it can be driven by a different motor; this disclosure does not limit this.

[0057] Based on the above structure, the surface cleaning device disclosed herein can apply two forces of different directions and magnitudes to the dirt during use, breaking the compliant state of stubborn stains on the single circular roller brush component, and greatly improving the cleaning ability of the surface cleaning device.
