[0035] 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.
[0036] 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.
[0037] 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.
[0038] Figure 1 This is a schematic diagram of a wet surface cleaning apparatus according to one embodiment of the present disclosure. Figure 2 This is a schematic diagram of the structure of a cleaning base according to one embodiment of the present disclosure.
[0039] The wet surface cleaning device disclosed herein is configured to perform wet cleaning on a surface to be cleaned, wherein the surface to be cleaned may be a floor surface, preferably a household floor surface. Furthermore, after the wet surface cleaning device performs wet cleaning on the floor surface, the dirt and liquid (sewage) remaining from cleaning the surface can be recycled back to the wet surface cleaning device.
[0040] The wet 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 wet surface cleaning device by operating the handle portion 100, so that during the operation of the wet surface cleaning device, the upright body can work in a manner substantially parallel to the surface to be cleaned.
[0041] The handle 100 may be equipped with a user interaction button, which allows the user to control the wet surface cleaning equipment by triggering the button, such as controlling the start and stop of the wet surface cleaning equipment, as well as controlling the liquid supply speed and suction power of the suction source.
[0042] The main body 200 is pivotally connected to the cleaning base 600 via the connecting part 500; thus, when the user operates the handle part 100, the cleaning base 600 can be moved on the surface to be cleaned, and the surface to be cleaned can be cleaned by the cleaning base 600.
[0043] In one example, the connection 500 may include a universal joint to allow the main body 200 to rotate relative to the cleaning base 600 in two directions. In another example, the connection 500 may include a multi-axis joint that couples the main body 200 to the cleaning base 600 to allow the main body 200 to rotate relative to the cleaning base 600 in a first direction and a second direction.
[0044] 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 cleaning base 600 (or the ground) is 80° to 90°, preferably around 80°. In this position, the wet surface cleaning device is in a self-supporting posture (also known as an upright posture), meaning that the main body 200 can be supported by the cleaning base 600, and an upright posture can be achieved without the aid of other objects.
[0045] The main body 200 can also accommodate components such as a clean water tank 300 and a wastewater tank 400. In this disclosure, the clean water tank 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 wastewater tank 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 clean water tank 300 of this disclosure can also be disposed on the cleaning base 600.
[0046] In one example, the thickness of the wastewater tank 400 is set to be less than its width, and the height of the clean water tank 300 is set to be less than its width. This ensures sufficient capacity and allows the overall height of the wet surface cleaning equipment to be less than a predetermined height, such as 120mm, after the main body 200 is laid flat.
[0047] The clean water tank 300 is used to store the cleaning liquid to be dispensed. Accordingly, the clean water tank 300 can be connected and fluidly communicated with a fluid distributor (not shown in the figure), so that the cleaning liquid in the clean water tank 300 can be pressurized by the fluid distributor and provided to the cleaning base 600, or to the surface to be cleaned near the cleaning base 600, thereby enabling wet cleaning of the surface to be cleaned by the cleaning liquid.
[0048] In one example, the fluid dispenser may include a supply pump capable of drawing cleaning liquid from a clean water tank 300, pressurizing the cleaning liquid, and supplying it to a discharge component, which then supplies the pressurized cleaning liquid to the roller brush 610 of the cleaning base 600 or to the surface to be cleaned near the roller brush 610.
[0049] 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.
[0050] The main body 200 has a receiving space, and the sewage tank 400 is detachably installed in the main body 200 and located in the receiving space, so that when the sewage tank 400 contains a lot of liquid, the user can remove the sewage tank 400, pour out the sewage inside and clean up the solid waste. At this time, part of the outer surface of the sewage tank 400 forms part of the outer surface of the wet surface cleaning device.
[0051] like Figure 2As shown, the cleaning base 600 of this disclosure may include a roller brush 610 and a vacuum suction port 620; wherein, the vacuum suction port 620 is located behind the roller brush 610, so that used cleaning liquid and dirt can enter the recovery pipeline through the vacuum suction port 620 and further flow to the wastewater tank 400. Moreover, the roller brush 610 of this disclosure can be driven to rotate about its own axis.
[0052] Based on the above structure, the wet surface cleaning equipment of this disclosure, with the wastewater tank 400 at its center, can form a liquid recovery system. Specifically, the liquid recovery system of this disclosure can include a suction source, which can be an electric suction source, capable of generating negative pressure during operation, and this negative pressure can be applied to the wastewater tank 400. Further, this negative pressure can be provided to the vacuum suction port 620 via the wastewater tank 400 and a pipe. In other words, the vacuum suction port 620 of this disclosure can be in fluid communication with the suction source.
[0053] Figure 3 This is a schematic diagram of the structure of a first embodiment of a roller brush of a wet surface cleaning apparatus according to one embodiment of the present disclosure. Figure 4 This is a schematic diagram of the structure of a second embodiment of the roller brush of a wet surface cleaning apparatus according to one embodiment of the present disclosure. Figure 5 This is a schematic diagram of the structure of a third embodiment of the roller brush of a wet surface cleaning apparatus according to one embodiment of the present disclosure.
[0054] The roller brush 610 disclosed herein may include a spindle and an action part disposed outside the spindle. Thus, when the wet surface cleaning equipment of the present invention is in use, the action of the roller brush 610 can make frictional contact with the surface to be cleaned, thereby cleaning the dirt on the surface to be cleaned by the roller brush 610.
[0055] In one specific embodiment, the functional part includes a first portion 611 forming a first region and a second portion 612 forming a second region. The material of the second portion 612 is different from that of the first portion 611, and the material of the second portion 612 has a greater density and higher water absorption than the material of the first portion 611.
[0056] To improve the cleaning effect of wet surface cleaning equipment, existing technologies generally use reciprocating roller brushes or add other cleaning components. This results in high energy consumption and short operating time for wet surface cleaning equipment. Moreover, adding other cleaning components increases manufacturing costs.
[0057] This disclosure improves the cleaning effect of wet surface cleaning equipment by designing the roller brush 610, which is made of two materials, so that the two materials can alternately rub against dirt.
[0058] In a preferred embodiment, the first part 611 is made of velvet, and the second part 612 is made of melamine resin foam. Specifically, the velvet disclosed herein can be fixed to the mandrel by means of adhesive bonding or other connection methods. Similarly, the second part 612 can also be fixed to the mandrel by means of adhesive bonding or other methods.
[0059] In this disclosure, the density of the melamine resin foam is greater than or equal to 16 kg / m³. Therefore, the melamine resin foam of this disclosure can be formed into a high-density compressed nano-sponge material. In this case, the second part 612 is not easily damaged, and correspondingly, the lifespan of the roller brush 610 is also improved.
[0060] See again Figures 3 to 5 The present disclosure includes one end of the roller brush 610 in the axial direction and the other end opposite to that end. The first region of the present disclosure is formed as a ribbon-like spiral extending from one end of the roller brush 610 to the opposite end of the roller brush 610, and the second region is defined between adjacent ribbon-like spirals.
[0061] Therefore, both a first material and a second material exist on the cross-section perpendicular to the axis of the roller brush 610. When the roller brush 610 is driven to rotate to rub against the dirt on the surface to be cleaned, the first material and the second material can alternately rub against the dirt, thereby improving the dirt removal effect. Accordingly, the wet surface cleaning device disclosed herein has a high dirt removal capacity.
[0062] When the working part is dry, the second portion 612 on the second region protrudes from the first portion 611 on the first region. When the working part is wet, the second portion 612 on the second region and the first portion 611 on the first region are substantially flush. Therefore, when the wet surface cleaning device of this disclosure is in use, the scraper can interfere with the working part of the roller brush 610 to the same depth. At this time, the scraper can remove dirt adhering to the first and second regions, thereby preventing this dirt from re-contaminating the surface to be cleaned and contaminating the already cleaned surface.
[0063] The first region of this disclosure can be formed as a continuous structure or as a discontinuous structure. For example, the first region contains a plurality of first portions 611, each of which can form an equal area. Thus, the first portions 611 can be manufactured in multiples by cutting, and workers can fix these first portions 611 one by one onto the mandrel, thereby making the roller brush 610 of this disclosure easy to manufacture.
[0064] In this disclosure, a line passing through the center of multiple first regions forms a spiral on the surface of the working part. As a result, when the roller brush 610 of this disclosure rotates, the first region and the second region can alternately rub against the same region. Therefore, the wet surface cleaning device of this disclosure has a better cleaning effect.
[0065] In some embodiments, the total area of the first region is less than or equal to the total area of the second region. In other words, the roller brush 610 of this disclosure is formed as a structure with the second material as the main body, thereby enabling the roller brush 610 of this disclosure to have a longer service life and better cleaning effect.
[0066] In this disclosure, when the first portions 611 are discretely arranged, these first portions 611 can be formed into a generally rectangular shape, thereby allowing a worker to install the first portions 611 onto the mandrel. Furthermore, these first portions 611 can be arranged on the same helix or on different helixes. Preferably, when these first portions 611 are arranged on different helixes, the helical directions of the two helixes can be opposite.
