Description

Technical Field

[0001] The invention relates to the field of floor scrubbers, and in particular provides a floor cleaning device. Background Art

[0002] Floor cleaning equipment has evolved from traditional mops and brooms to automated mechanical cleaning, such as sweeping robots and floor scrubbers. The cleaning principle of floor scrubbers is to use motors to drive rollers and other components to rotate at high speeds, and spray water onto the rollers through nozzles, so that floor scrubbers can efficiently clean the floor and remove stubborn stains.

[0003] However, relying solely on ordinary roller brushes and cold water to clean floor stains cannot effectively soften and dissolve stubborn dirt on the floor surface, causing some dirt to remain or redistribute to other areas, which may cause secondary pollution. At the same time, due to the limited effect of cold water cleaning, using traditional floor scrubbers may require longer cleaning time and multiple cleanings to achieve the desired cleaning effect.

[0004] Accordingly, the art needs a new technical solution to solve the above problems. Summary of the invention

[0005] The present invention aims to solve the above technical problems and the problem that the existing cold water washing effect is limited and the cleaning effect is not ideal.

For example, "connection" can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or other connections; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. It should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", etc. is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0046] like Figure 1-12 As shown, in order to solve the problem that the existing cold water cleaning effect is limited and the cleaning effect is not ideal, the present invention provides a floor cleaning device, including a housing and a roller brush assembly, the housing is formed with a receiving recess 41 for accommodating the roller brush assembly, the roller brush assembly is arranged in the receiving recess 41 and is used to clean the floor;

[0047] The cleaning device also includes a water storage tank 71 and a first heating assembly 73, the first heating assembly 73 is used to heat the liquid flowing to the roller brush assembly;

[0048] The housing is provided with a spraying member 74, which is connected to the water storage tank 71 and is arranged toward the roller brush assembly, and is used to spray the hot water heated by the first heating assembly 73 onto the roller brush assembly;

[0049] The roller brush assembly includes a roller brush body 1 and a second heating assembly. The roller brush body is disposed in the accommodating recess 41 . The second heating assembly is connected to the roller brush body 1 , and is used to heat the roller brush body 1 .

[0050] In this way, the first heating component 73 can heat the liquid flowing to the roller brush component, and the second heating component can heat the roller brush body, so that the liquid used for washing the floor is further heated. The first heating component 73 and the second heating component are set so that the liquid used for washing the floor is heated twice, and when washing the floor, it can reach a higher temperature, and the cleaning effect is better for some stains that need to be dissolved at high temperature. At the same time, when it is necessary to wash the floor at a low temperature, only one second heating device needs to be turned on, which can effectively save energy and can be applied to floors with different heating temperature requirements, and has a wider range of applications.

[0051] See attached Figure 9-12 In a floor cleaning device provided in a preferred embodiment of the present invention, the floor cleaning device includes a housing 4, a roller brush assembly, a handheld frame 6, a water storage tank 71, a water guide channel and a first heating assembly 73.

[0052] On both sides of the housing 4, there are respectively formed accommodating recesses 41 for accommodating a roller brush assembly. There are two roller brush assemblies, which are respectively arranged in the two accommodating recesses 41 and are used to clean the floor. The housing 4 is provided with a spraying member 74, which is arranged toward the roller brush assembly. One end of the handheld frame 6 is connected to the housing 4, and an armrest is arranged on the other end of the handheld frame 6, and a mounting groove for mounting a water storage tank 71 is formed on the handheld frame 6. A power supply terminal 42 is arranged on the accommodating recess 41, and the power supply terminal 42 is used to supply power to the roller brush assembly.

[0053] It should be noted that the provision of the accommodating recess 41 is not mandatory, and those skilled in the art may choose whether to provide the accommodating recess 41 and the specific structure of the accommodating recess 41 based on the specific application scenario. Of course, the accommodating recess 41 may not be provided.

[0054] The water tank 71 is embedded in the mounting groove, one end of the water channel is connected to the water tank 71, and the other end of the water channel is connected to the spraying member 74. A pump body 72 is connected to the handheld frame 6, and the pump body 72 is connected to the water channel. The pump body 72 can pump the liquid in the water tank 71 to the spraying member 74. The first heating component 73 is arranged in the housing 4, and is used to heat the water in the water channel. The spraying member 74 can spray the hot water heated by the first heating component 73 onto the roller brush assembly.

[0055] The number of the spraying parts 74 is also set to two, and the two spraying parts 74 spray the two roller brush assemblies respectively. The spraying part 74 includes a long strip spraying shell, the length of the spraying shell is less than or equal to the length of the cleaning part, and a nozzle is opened on the side of the spraying shell facing the roller brush assembly, and the first spraying part 74 is fixedly connected to the housing 4.

[0056] It should be noted that the position and specific arrangement of the spraying member 74 can also be adjusted according to actual needs. For example, the spraying member 74 can be arranged above the roller brush assembly, and the nozzle can be arranged at the lower side of the spraying member 74 and facing the roller brush assembly. In this case, water flows from above to the roller brush assembly. In addition, the appearance and arrangement of the spraying shell or the nozzle are not unique, as long as they can achieve the spraying effect.

[0057] The pump body 72 can pump water to the two spray parts 74 respectively through the bifurcated pipe. After the water is sent to the spray parts 74 by the pump body 72, the water is evenly sprayed to the part of the roller brush body 1 used for washing the floor because the spray parts 74 are evenly provided with nozzles. Of course, although in this embodiment, due to the position relationship of the spray shell, its length needs to be less than or equal to the length of the roller brush assembly, the two ends of the roller brush assembly can be wetted by changing the angle of the nozzle toward the roller brush assembly.

[0058] It should be noted that the pump body 72 is not necessarily provided. Those skilled in the art can choose whether to provide the pump body 72 and the specific structure of the pump body 72 based on the specific application scenario. Of course, the pump body 72 may not be provided. The liquid in the water storage tank 71 reaches the nozzle and is sprayed out under the action of gravity. Of course, the pump body 72 may be provided in the housing 4 or on the handheld frame 6.

[0059] The first heating component 73 is heated by a ceramic heater, and of course, it can also be heated by an electric heating rod, a metal heating wire, etc., as long as it can heat the water flow, and can heat the water in the water guide channel and the water in the water storage tank 71. Fig. 9As shown, it should be noted that the water in the water tank 71 passes through the pump body 72, the first heating component 73 and the spraying part 74 in sequence, and the water is sprayed onto the roller brush body 1 through the spraying part 74. Of course, the above water flow sequence is the best, and other flow modes can also be used, such as the water in the water tank 71 passes through the first heating component 73, the pump body 72 and the spraying part 74 in sequence; or the first heating component 73 heats the water in the water tank 71, and then passes through the pump body 72 and the spraying part 74.

[0060] It should be noted that the handheld frame 6 is not necessarily provided, and those skilled in the art can choose whether to provide the handheld frame 6 and the specific structure of the handheld frame 6 based on the specific application scenario. Of course, the handheld frame 6 may not be provided, and the water storage tank 71, the pump body 72, etc. may be directly provided on the upper side of the housing 4. Accordingly, on the basis of not providing the handheld frame 6, the armrest is not necessarily provided.

[0061] The structure of the roller brush assembly is described below.

[0062] In a floor cleaning device provided in a preferred embodiment of the present invention, the roller brush assembly includes a roller brush body 1, a plug-in portion 22, a fixing portion 21, an end cover 3, a second heating assembly and a driving assembly. The second heating assembly includes a heating wire 51 and a heating element 52, the heating wire 51 is electrically connected to the heating element 52, and the heating element 52 can generate heat when powered.

[0063] The roller brush body 1 is a hollow tubular structure. A heating element 52 is connected to the outside of the roller brush body 1 . Bristles 11 for cleaning the floor are arranged on the outside of the heating element 52 .

[0064] See attached Figure 3-8 The plug-in portion 22 includes a plug-in block 221 and a mounting rod 222. The plug-in block 221 is a cylindrical shape with one end open. The bottom surface and the inner side wall of the plug-in block 221 are formed with a wire groove 225, and the wire groove 225 is used for the heating wire 51 to pass through. The open end of the plug-in block 221 is provided with a flange 2211 to the outside. The plug-in block 221 is inserted into the roller brush body 1, and the flange 2211 abuts against the end surface of the roller brush body 1. The flange 2211 is provided with a notch 226 for the heating wire 51 to pass through. The abutment of the flange 2211 with the end surface of the roller brush body 1 can prevent liquid from entering the roller brush body 1, improve the waterproof performance of the roller brush body 1 and the plug-in block 221, and can be conveniently connected to the heating element 52 through the notch 226.

[0065] It should be noted that, for the sake of convenience, the wire-releasing groove 225 provided on the bottom surface of the plug-in block 221 is named as the first wire-releasing groove, and the wire-releasing groove 225 provided on the inner side surface of the plug-in block 221 is named as the second wire-releasing groove. The first wire-releasing groove is formed by the bottom surface of the plug-in block 221 being recessed downward, and two guide plates 227 are fixedly connected to the side surface of the plug-in block 221, and the two guide plates 227 and the inner side wall of the plug-in block 221 are surrounded to form the second wire-releasing groove.

[0066] See Appendix Figure 7 The mounting rod 222 is formed at the cylindrical bottom of the plug-in block 221. The mounting rod 222 is coaxially arranged with the plug-in block 221, and a connecting hole is provided on the mounting rod 222. The connecting hole is used to plug the connecting shaft 23. The fixed part 21 and the plug-in part 22 are rotatably connected through the connecting shaft 23. It should be noted that the plug-in block 221 and the mounting rod 222 are described separately here only for the convenience of clear description. Of course, the plug-in block 221 and the mounting rod 222 can be integrally formed or fixedly connected.

[0067] The mounting rod 222 is provided with a first conductive component, which includes a conductive ring 24. The cross section of the conductive ring 24 is square. There are two conductive rings 24. The conductive rings 24 are sleeved on the mounting rod 222 and fixed to the mounting rod 222. At the same time, the mounting rod 222 is also provided with a limiting rib 224. A limiting groove 241 is provided on the inner side of the conductive ring 24. When the conductive ring 24 is sleeved on the mounting rod 222, the limiting rib 224 is inserted into the limiting groove 241, which can prevent the conductive ring 24 and the mounting rod 222 from rotating relative to each other. There are two limiting ribs 224 and two limiting grooves 241.

[0068] See attached Figure 3-6The fixing part 21 includes a fixing base 214, a wire fixing plate 211 and a bearing 215, and the second conductive component includes a spring piece 217 and a conductive block 218. The fixing base 214 is plugged into the plug-in part 22, and a bearing 215 is provided in the fixing base 214. A connecting shaft 23 passes through the bearing 215, and the connection between the fixing part 21 and the plug-in part 22 is realized through the connecting shaft 23, and the rotation between the fixing part 21 and the plug-in part 22 is realized through the bearing 215. The connecting shaft 23 ensures that when the fixing part 21 and the plug-in part 22 rotate relative to each other, the rotation axis of the fixing part 21 and the plug-in part 22 will not change, thereby making the connection between the conductive block 218 and the conductive ring 24 more stable. The fixing base 214 is provided with a fixing protrusion 216. One end of the spring sheet 217 is located on the upper side of the fixing protrusion 216. The spring sheet 217 is fixedly connected to the fixing protrusion 216 by a bolt, and a threading hole 219 is provided on the end. The other end of the spring sheet 217 is fixedly connected to the conductive block 218. The elastic force of the spring sheet 217 makes the conductive block 218 always in a state of pressing the outer surface of the conductive ring 24. The first end ( Figure 6 The middle wire fixing plate 211 is close to the right side) and is connected to one end of the outer side of the fixing base 214. The second end of the wire fixing plate 211 ( Figure 6 A clamping protrusion 2112 is formed on the side of the roller brush body 1 (close to the left side of the middle wire fixing plate 211), and a conductive sheet 213 is connected to the clamping protrusion 2112. A part of the conductive sheet 213 is located on the side where the clamping protrusion 2112 is flush with the wire fixing plate 211. The conductive sheet 213 on the outside of the clamping protrusion 2112 is conveniently connected to the power supply end. A wire groove 2111 is provided on the side of the wire fixing plate 211 away from the roller brush body 1, and one end of the conductive sheet 213 is located in the wire groove 2111. One end of the wire is connected to the conductive sheet 213, and the other end of the wire is connected to the threading hole 219 of the spring 217, and the wire passes through the wire groove 2111. A cover plate 212 is provided on the side of the wire fixing plate 211 away from the roller brush body 1, and the cover plate 212 can prevent the wire from being exposed to the outside.

[0069] See attached Figure 4 The heating element 52 is located on the outside of the roller brush body 1 and is used to heat the roller brush body 1. A driving groove is provided at one end of the end cover 3 close to the outside. The driving groove is used to cooperate with the driving component of the roller brush body 1, so that the roller brush body 1 rotates under the action of the driving component.

[0070] There are two heating wires 51, one end of each of which is electrically connected to two conductive rings 24, and two wire-releasing grooves 225 are also provided. The two heating wires 51 pass through different wire-releasing grooves 225 and are fixed in the wire-releasing grooves 225 to prevent the heating wires 51 from being displaced during the rotation of the roller brush assembly, thereby causing unstable power supply to the heating element 52. The heating element 52 is composed of a heating film, which is wound around the outside of the roller brush body 1, and the two poles of the heating element 52 are connected to the two heating wires 51, respectively.

[0071] Other possible implementations of the present invention are described below.

[0072] In an alternative embodiment, the formation method and setting position of the wire placing groove 225 are the best choices. The wire placing groove 225 can also be set in other ways as long as it can be used to place the heating wire 51. For example, two guide plates 227 are set on the bottom surface of the plug-in block 221, and a first wire placing groove is formed between the two guide plates 227 and the bottom surface. Alternatively, the inner side surface of the plug-in block 221 is recessed outward to form a second wire placing groove. Furthermore, the wire placing groove 225 can also be omitted, and a buckle capable of fixing the heating wire 51 can be fixedly connected to the bottom surface and the inner side wall of the plug-in block 221.

[0073] In an alternative embodiment, the notch 226 is not required. A person skilled in the art can choose whether to set the notch 226 and the shape of the notch 226 according to the specific application environment, as long as the heating wire 51 can pass through. For example, the notch 226 can also be a circular opening or an opening of other shapes. Of course, the notch 226 can also be set on the side wall of the plug block 221 without setting the notch 226 on the flange 2211. Alternatively, the notch 226 is not set, and an opening for the heating wire 51 to pass through is set on the edge of one end of the roller brush body 1.

[0074] An alternative embodiment, the above-mentioned setting positions of the heating wire 51 and the heating element 52 are the best choice. Of course, the heating wire 51 and the heating element 52 can also be set at other positions, as long as the roller brush body 1 can be heated. For example, the heating wire 51 and the heating element 52 are both located inside the roller brush body 1, and there are two heating wires 51, and one end of the two heating wires 51 is electrically connected to the two conductive rings 24 respectively. The heating element 52 is fixedly connected to the inside of the roller brush body 1, and the two poles of the heating element 52 are respectively connected to the two heating wires 51. Of course, the heating element 52 can also be constructed in other forms. For example, the heating element 52 can also be made of other materials that can generate heat, such as ceramic heating sheets or nano heating films.

[0075] In an alternative implementation, the first conductive component and the second conductive component may also adopt other structures. The first conductive component includes a spring sheet 217 and a conductive block 218 , and the second conductive component includes a conductive ring 24 .

[0076] There are two conductive rings 24 , which are sleeved on the fixed base 214 and fixed to the fixed base 214 .

[0077] One end of the spring sheet 217 is fixedly connected to the outer side of the mounting rod 222, and a threading hole 219 is provided on the end. The threading hole 219 is connected to the heating element 52 through the heating wire 51. The other end of the spring sheet 217 is fixedly connected to the conductive block 218, and the elastic force of the spring sheet 217 makes the conductive block 218 always in a state of pressing the outer surface of the conductive ring 24.

[0078] An alternative embodiment, the provision of a driving groove is not necessary, and a person skilled in the art may select a specific structure of the driving groove based on a specific application scenario. Of course, the driving groove may not be provided, and a driving protrusion that can cooperate with the driving assembly of the roller brush assembly may be provided.

[0079] In an alternative embodiment, the connection shaft 23 is not necessary. Those skilled in the art can choose whether to set the connection shaft 23 and the specific structure of the connection shaft 23 based on the specific application scenario.

[0093] The possible operation modes of the present invention are introduced below.

[0094] First, install the roller brush, and sleeve the driving groove at one end of the roller brush on the outside of the driving assembly so that the driving assembly can drive the roller brush to rotate.
