Description

Technical Field

[0001] The present invention relates to the technical fields of electric mops with roller brushes, floor scrubbers, vacuum cleaners, sweepers, and the like, and in particular to a roller brush and a cleaning device. Background Art

[0002] In cleaning devices such as roller brush electric mops, floor scrubbers, vacuum cleaners, and sweepers, the roller brush is one of the important technical means to improve cleaning performance. The general working principle of the roller brush is that the roller brush rotates in contact with the surface to be cleaned and cleans the surface through contact.

[0003] In order to improve the cleaning performance, it has been proposed to spray cleaning liquid on the roller brush or before and after the roller brush, such as detergent, water, etc. In this way, the cleaning performance is improved by wetting the roller brush or the surface to be cleaned. In addition, in order to further improve the cleaning performance, it has been proposed to heat the cleaning liquid, that is, to use hot cleaning liquid to improve the cleaning performance. However, there are currently many different solutions for how to produce and supply hot cleaning liquid. They can be roughly divided into two types: one is to use electric heat or chemical energy to heat the cleaning liquid in the storage tank, and the storage tank and the roller brush are connected by a pipeline. The transported cleaning liquid is sprayed on the roller brush or the surface to be cleaned. There are roughly two types of spraying on the roller brush, one is to spray on the upper side of the outside of the roller brush, and the other is to divert from the inside of the roller brush and then seep out from the cleaning part of the roller brush. This solution has a long transportation distance, high energy consumption, and slow response. In addition, it involves the problem of high-pressure and high-heat storage after the liquid storage tank is heated. How to maintain Safety is a big problem; the other is a solution specially proposed by the present applicant, that is, heating directly in the roller brush, and after the heated roller brush encounters the cleaning liquid, it indirectly heats the cleaning liquid, thereby obtaining a thermal cleaning effect. Compared with the original technology, this solution further shortens the conveying path, which is beneficial to energy saving and improving response performance, and the safety problem is also better solved. In addition, by setting up an electrical connection structure, the present applicant does not need to set batteries at both ends of the barrel of the roller brush or in the barrel, but is powered by the power supply of the cleaning device. On the one hand, it increases the power supply capacity and ensures endurance. On the other hand, it reduces the cost of replacing the roller brush, so that the roller brush proposed by the present applicant can be actually used in life, rather than theoretically. However, even though the roller brush proposed by the present applicant has the above-mentioned advantages, the present applicant also hopes to further improve the energy utilization efficiency and response performance, which is of great significance for reducing battery volume, reducing costs and improving practicality.

[0004] Therefore, the applicant continued to conduct in-depth research, and through the unremitting efforts of the applicant, the applicant proposed a roller brush, which is provided with a heating part, which is in contact with and / or has a gap with the outer periphery of the rotating cylinder. The heating part is used to heat the cleaning part of the rotating cylinder and / or the cleaning liquid supplied to the cleaning part. This structure can further improve energy utilization efficiency and response performance. In the aforementioned scheme, the heating part is located on one side of the rotating cylinder and is provided with a liquid outlet hole, and each liquid outlet hole is arranged in sequence along the liquid outlet flow channel. Since the heating part is in contact with and / or has a gap with the outer periphery of the rotating cylinder, dirt may enter the liquid outlet hole, which makes cleaning difficult. If it is not cleaned or replaced, the heating part may not work normally, thereby reducing the reliability of the aforementioned scheme. In addition, if the blockage is too serious and can only be replaced, the heating part will be scrapped, which increases the cost. Therefore, the applicant proposed a roller brush through research to solve this problem. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the existing technology and propose a roller brush that is easier to handle once the liquid outlet structure is blocked, thereby helping to improve the reliability of the roller brush and reduce costs; a cleaning device is also proposed, including the roller brush.

[0012] Preferably, the main body is sintered and provided with a heating element.

[0013] Preferably, the main body is provided with a heating element and a heat insulating layer, and the heat insulating layer is used to conduct the heat of the heating element to the main body.

[0014] Preferably, a bracket is further included, and the main body and the bracket are distributed and connected along the front-to-back direction.

[0015] Preferably, the bracket has a concave cavity that cooperates with the main body, the upper edge of the concave cavity and the upper edge of the main body are sleeved together along the axial direction of the rotating cylinder through a first sleeve structure, and the lower edge of the concave cavity and the lower edge of the main body are sleeved together along the axial direction of the rotating cylinder through a second sleeve structure.

[0016] Preferably, the bracket is made of a heat-insulating material, and the bracket serves as a heat-insulating layer for the heating element, and the heat-insulating layer is used to conduct the heat of the heating element to the main body.

[0017] Preferably, in the case where flow channels are provided in the main body, there are multiple flow channels in the main body, and at least one of the two ends of the main body is provided with a transition groove, which is used to connect adjacent flow channels.

[0018] Preferably, a sealing member is provided at one end of the main body having the transition groove, and a transition flow channel is formed by the cooperation between the sealing member and the transition groove.

[0019] Preferably, it also includes a protrusion that can be sleeved and matched with the transition groove.

[0020] Preferably, it further includes a bracket, the main body and the bracket are distributed and connected along the front-to-back direction, the liquid inlet component is located on one side of the bracket and the other end of the bracket is respectively provided with the said protrusion, and the protrusion at the other end of the bracket can also be used as the other end of the main body fixed to the other end of the bracket.

[0022] Preferably, the main body adopts an arc structure arranged along the circumference of the rotating cylinder, and a labyrinth flow channel is provided in the main body.

[0023] Preferably, the liquid inlet connector is connected to one end of the main body, is communicated with the flow channel, and is used to connect to the liquid supply component.

[0024] Preferably, the liquid outlet member is provided on one side of the rotating cylinder with a recess extending along the axis of the rotating cylinder, and a liquid outlet hole is provided in the recess.

[0025] Preferably, the liquid outlet is located on the side surface of the recessed portion facing the counter-rotating cylinder.

[0026] After adopting the above structure, compared with the prior art, the present invention has the following advantages:

[0027] The present invention includes a heating part and a liquid outlet part that can be separated from each other. The heating part includes a heat conductive part and a heating part. The heat conductive part and the liquid outlet part are all circumferentially arranged around the outer periphery of the rotating cylinder. Therefore, the liquid outlet structure and the heating part are two separable components. Once the liquid outlet structure is blocked, the liquid outlet structure can be removed separately for cleaning or replacement. After such a design, on the one hand, there is no need to deal with the heating part. On the other hand, when the blockage is too serious and can only be replaced, the heating part will not be scrapped and only the liquid outlet structure needs to be replaced. Therefore, the convenience of handling is improved and the cost is reduced, which is conducive to improving the reliability of the roller brush.

[0028] The heat conducting member is in contact with and / or has a gap fit with the outer periphery of the rotating cylinder. The heat conducting member is used to heat the cleaning part of the rotating cylinder and / or the cleaning liquid supplied to the cleaning part. Therefore, the heat generated by the heating member can be transferred to the cleaning part and / or the cleaning liquid supplied to the cleaning part as quickly as possible, and can be effectively used immediately after being transferred. The heating of the cleaning liquid supplied to the cleaning part refers to two situations. One is that the cleaning part that has been moistened (for example, moistened with a liquid outlet) heats the cleaning liquid in the cleaning part when it passes through the heating part. The other is that the cleaning liquid is heated when it falls on the cleaning part, and / or the cleaning liquid is heated before it falls on the cleaning part. For example, the cleaning liquid first passes through the heating member and / or the heat conducting member, and then is output to the cleaning part by the liquid outlet. After such a design, the heated cleaning liquid immediately falls on the cleaning part to participate in the subsequent cleaning work. The heat utilization rate is very high and there is very little waste.

[0029] Since the heat-conducting member is in contact with and / or has a clearance fit with the outer periphery of the rotating cylinder, the heat-conducting member is used to heat the cleaning portion of the rotating cylinder and / or the cleaning liquid supplied to the cleaning portion, so less heat is required to reach a certain temperature during heating, which can greatly improve the response performance. That is, after the heating portion is turned on, in the present invention, the cleaning portion of the rotating cylinder and / or the cleaning liquid supplied to the cleaning portion can quickly reach the required operating temperature, thereby greatly improving the response performance.

[0030] Compared with the prior art, the present invention further provides a cleaning device, which includes the roller brush.

[0031] After adopting the above structure, compared with the prior art, the present invention has the following advantages: the cleaning device using the roller brush can achieve better cleaning performance while greatly improving energy utilization efficiency and response performance. In addition, it is conducive to achieving longer battery life with the same battery and the same operating temperature. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0049] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0050] The present invention will be further described in detail below:

[0051] The present disclosure provides a cleaning device, which includes the roller brush. Figure 1 shown.

[0052] Cleaning devices such as roller brush electric mops, vacuum cleaner nozzles, sweepers, floor scrubbers, etc. The cleaning devices referred to in this application generally refer to household or small cleaning devices. This is also a feature of the roller brush of the present invention. It requires the overall structure to be small in size and can be suitable for small cleaning devices.

[0053] The roller brush exemplified in the present disclosure includes a rotating cylinder 3. Of course, there can be multiple rotating cylinders 3, such as two or three, but no matter how many there are, they can be obtained by making adaptive adjustments or simply copying them with reference to the solution of one. The present invention also points out that when there are multiple rotating cylinders 3, at least one rotating cylinder 3 is provided with the heating part of the present invention. When it is necessary to set a heating part for multiple rotating cylinders 3, it can be cleverly set as follows, that is, to set a heating part between two adjacent rotating cylinders 3, that is, to set a heating part for two adjacent rotating cylinders 3 to share a heating part, but at this time, both sides of the heating part can transfer heat to the corresponding rotating cylinder 3, such as setting a heating element 5 on each side, or after the transition water tank 6 is heated, the transition water tank 6 transfers heat to the corresponding rotating cylinder 3 on both sides.

[0054] The cleaning part of the rotating cylinder 3 is generally the outermost layer, and the thickness is determined according to the cleaning performance or the requirements of the surface to be cleaned. By adopting the solution of the present invention, there is no need to modify the original structure of the rotating cylinder 3, that is, the existing rotating cylinder 3 can be used, and the cost of replacing and using the rotating cylinder 3 for the user is almost unchanged.

[0055] There are many situations in which the cleaning liquid can be used in combination, such as using other equipment to sprinkle it on the surface to be cleaned, such as manual active water sprinkling, and the heated cleaning part will meet the wet surface to be cleaned, which will also achieve a better cleaning effect. At this time, the heated object is the cleaning part. For example, the cleaning device is provided with other liquid supply structures, such as the liquid outlet part disclosed in the present invention, which sprays the cleaning liquid on the cleaning part, and the cleaning part with the cleaning liquid is heated for use. If the surface to be cleaned is dry, it will also achieve a better cleaning effect under the action of the heated wet cleaning part. For example, as described in the following embodiments, the scheme includes a labyrinth flow channel and / or a transition water tank. For example, the above-mentioned situations can be used in combination, that is, there can be both manual water sprinkling and a liquid supply structure to spray and supply cleaning liquid, or there can be both a liquid supply structure to spray and supply cleaning liquid and a transition water tank, etc., which are not listed here one by one.

[0056] The water or water-related descriptions mentioned in the present disclosure do not only refer to water, but are common names. For example, a cleaning liquid tank is often called a clean water tank. The water here refers to cleaning liquid. The cleaning liquid can be pure water, a mixture of water and detergent, or a mixture of water and disinfectant.

[0057] like Figures 1 to 6 As shown, the present disclosure provides a roller brush, including a heating part and a liquid outlet that can be separated from each other. The heating part includes a heat-conducting part 4 and a heating part 5. The heat-conducting part 4 and the liquid outlet are circumferentially arranged around the outer periphery of the rotating cylinder 3. The heating part 5 is thermally connected to the heat-conducting part 4. The heat-conducting part 4 is in contact with and / or has a clearance fit with the outer periphery of the rotating cylinder 3. The heat-conducting part 4 is used to heat the cleaning part of the rotating cylinder 3 and / or the cleaning liquid supplied to the cleaning part; along the rotation direction of the rotating cylinder 3, the liquid outlet is located at the front and / or rear side of the heat-conducting part 4, and the liquid outlet is used to output the cleaning liquid. With this design, once a blockage occurs, only the liquid outlet needs to be cleaned, for example Figure 4 As shown, the roller brush has a transition water tank 6, which has a heating part and a liquid outlet that can be separated from each other. When blocked, the transition water tank 6 can be taken out and the liquid outlet 7 can be cleaned. There is no need to clean the heating part. When the blockage causes it to have to be replaced, the heating part can be reused.

[0058] like Figures 8 to 15As shown, the present disclosure provides another roller brush, which is different from the above roller brush in that the transition water tank 6 is cancelled, that is, the function of the heating part is not provided by the transition water tank 6. With this design, once a blockage occurs, only the liquid outlet part needs to be cleaned, for example Figure 8 、 9 As shown, the liquid outlet is connected to the lower side of the upper cover 2, and can be designed so that when the upper cover 2 is removed, the upper cover 2 is removed together with the liquid outlet, and the liquid outlet can be detachably connected to the heat conducting member 4, or can be separately provided. When the liquid outlet is detachably connected to the heat conducting member 4, it can be designed so that when the upper cover 2 is removed, the upper cover 2 is removed together with the liquid outlet, and the liquid outlet is separated from the heat conducting member 4 by the detachable connection, so that the heat conducting member 4 remains on the roller brush and is not removed, for example Figure 8 、 9 As shown in FIG11 , a bayonet 27 is provided on the front edge of the liquid outlet, and the bayonet 27 is detachably connected to the heating portion. The supply of cleaning liquid to the liquid outlet can be done by the liquid supply component directly, or the liquid supply component first supplies the cleaning liquid to the heating component 5 and / or the heat conducting component 4, and then supplies the cleaning liquid to the liquid outlet after the heating component 5 and / or the heat conducting component 4 is heated. For example, Figure 9 、 13 As shown in Figures 15 and 16, the main body 17 is provided with a flow channel, the outlet of which is connected to the inlet of the liquid outlet component via a detachable connecting tube 28. The liquid supply assembly delivers cleaning liquid into the flow channel through the liquid inlet 15 of the flow channel. After removing the liquid outlet component, the liquid outlet hole 7 can be cleaned without cleaning the heating unit. If a blockage requires replacement, only the liquid outlet component needs to be replaced, and the heating unit remains on the roller brush frame 1 without any operation or replacement. In other words, the heating unit can be reused.

[0059] In some embodiments, the liquid outlet member is provided with a liquid outlet channel 14 , and each liquid outlet hole 7 is connected to the liquid outlet channel 14 .

[0060] In some embodiments, the liquid outlet channel 14 is preferably a linear channel, which can be parallel to the axis of the rotating cylinder 3 or inclined to the axis of the rotating cylinder 3. The main body or transition water tank is provided with a liquid outlet channel 14 arranged along the axis. This does not require that the liquid outlet channel 14 must be arranged parallel to the axis. Instead, it requires that each liquid outlet hole 7 can cover the clean part of the rotating cylinder 3. Therefore, the liquid outlet channel 14 needs to be able to transport liquid to each liquid outlet hole 7.

[0061] In some embodiments, in order to facilitate production and assembly, the following design is made: Figure 10 、 12As shown in Figures 13, 14, and 15, the heating part has a liquid inlet connector 16, a bracket 18, and a main body 17 extending along the axial direction of the rotating cylinder 3. The main body 17 and the bracket 18 are distributed and connected along the front-to-back direction. A flow channel extending along the axial direction of the rotating cylinder 3 is provided in the main body 17. The liquid inlet connector 16 is connected to one end of the main body 17. The liquid inlet connector 16 is connected to the flow channel. The liquid inlet connector 16 is used to connect the liquid supply component. The liquid inlet connector 16 is located on the side of one side of the bracket 18. The liquid inlet connector 16 is connected to the flow channel, which means that the liquid outlet 23 is connected to the flow channel inlet. With the bracket 18, after such a design, due to the support of the bracket 18, it is beneficial to further reduce the thickness of the main body 17, thereby further improving the energy utilization rate.

[0062] In some embodiments, the assembly order of the heating unit can be: the main body 17 is inserted along one end of the bracket 18, so that the main body 17 and the bracket 18 are connected along the axis of the rotating cylinder 3, and then the liquid inlet connector 16 is connected to one end of the bracket 18 and / or the liquid inlet connector 16 is connected to one end of the main body 17, for example Figure 14 As shown, the liquid inlet connector 16 is provided with two screw through holes 24, and correspondingly, one end of the main body 17 is also provided with two threaded holes 25. The screws connect and fix the liquid inlet connector 16 to one end of the main body 17 through the screw through holes 24 and the threaded holes 25. At the same time, the side of the liquid inlet connector 16 on one side of the bracket 18 closes the opening of one end of the bracket 18. A sealing gasket is provided on the side of the liquid inlet connector 16 on one side of the bracket 18. The side of the liquid inlet connector 16 on one side of the bracket 18 is tightly pressed and fixed to the end face of one end of the bracket 18 through the sealing gasket. A screw through hole 24 can also be provided at the other end of the bracket 18. Correspondingly, a threaded hole 25 is also provided at the other end of the main body 17. The screws connect and fix the other end of the main body 17 to the other end of the bracket 18 better through the screw through holes 24 and the threaded holes 25. As shown Figure 12 、 13 As shown, the bracket 18 has a concave cavity, and the upper edge and lower edge of the concave cavity are respectively engaged with the upper edge and lower edge of the main body 17 through a concave-convex socket structure. In this example, for example Figure 16 As shown, the grooves of the concave-convex socket structure are provided on the upper and lower edges of the main body 17, and the upper and lower edges of the cavity are correspondingly provided with protrusions 19 of the concave-convex socket structure. Such a structural design makes assembly very convenient and, in addition, provides more reliable support for the main body 17.

[0063] In some embodiments, the flow channel in the main body 17 is not one, but multiple, which is conducive to forming a maze flow channel, such as Figure 13 、 15As shown, there are four flow channels in the main body 17, which are arranged in parallel to each other to form a serpentine labyrinth flow channel, and the outlet of the last flow channel is connected to the liquid outlet through a connecting pipe 28. In order to simplify manufacturing, transition grooves 20 are processed at both ends of the main body 17. The transition grooves 20 are used to connect adjacent flow channels. For the closure of the transition grooves 20, for example, a sealing member can be provided at each end of the main body 17. For example, a protrusion 21 serving as a seal is provided on one side of the bracket 18 on the liquid inlet joint 16 and on the other end of the bracket 18. A transition flow channel is formed by the cooperation of the protrusion 21 and the transition groove 20. The protrusion 21 at the other end of the bracket 18 can also be used as the other end of the main body 17 fixed to the other end of the bracket 18 after the main body 17 and the bracket 18 are sleeved, thereby greatly facilitating production and manufacturing.

[0064] In some embodiments, as Figure 9 、 12 As shown in , 13 and 14, the main body 17 adopts an arc structure arranged along the circumference of the rotating cylinder 3, and a labyrinth flow channel is provided in the main body 17. The labyrinth flow channel starts from one end of the arc structure and extends back and forth along the axial direction of the rotating cylinder, for example, forming the serpentine labyrinth flow channel.

[0065] In some embodiments, as Figure 14 As shown, the main body 17 is further provided with a heating element 5, which is thermally connected to the main body 17. For example, the heating element 5 is provided on the back of the main body 17. This is beneficial to protecting the heating element 5 on the one hand and simplifying production on the other hand.

[0066] In some embodiments, an installation groove is provided on the back of the main body 17, and the heating element 5 is provided in the installation groove. This is beneficial to reducing the overall thickness of the assembly formed after the main body 17 and the heating element 5 are connected, and on the other hand, a certain wrapping is formed on the heating element 5, so that more heat is conducted to the main body 17.

[0067] In some embodiments, as Figure 14 As shown, the heating element 5 is sintered on the back of the main body 17. For example, an electric heating material is coated on the back of the main body 17 and sintered. In this way, the heating element 5 is more firmly combined with the main body 17 and roughly forms an integral body. This design is conducive to smaller heat conduction losses and smaller overall thickness of the assembly formed after the main body 17 and the heating element 5 are connected.

[0068] In some embodiments, a heat insulating layer is provided on the back of the main body 17, and the heat insulating layer is used to conduct the heat of the heating element 5 to the main body 17. This is conducive to energy saving, improving the utilization rate of heat energy, and reducing waste.

[0069] In some embodiments, a separate insulation layer can be provided on the back of the main body 17, or the bracket 18 can serve as the insulation layer for the heating element 5. The bracket 18 can be made of an insulating material, which can further simplify the structure. However, if a separate insulation layer is used, the material selection of the bracket 18 is simplified, and the bracket 18 is not restricted to using insulating materials. However, the assembly step is relatively extra, namely, the need to provide a separate insulation layer.

[0070] The following examples further illustrate the roller brush of the present disclosure:

[0071] Example 1:

[0072] The present invention discloses a roller brush comprising a rotating cylinder 3, with a heating portion provided circumferentially around the outer periphery of the rotating cylinder 3. The heating portion is in contact with the outer periphery of the rotating cylinder 3 and is used to heat the cleaning portion of the rotating cylinder 3. In this way, the heat generated by the heating portion is directly in contact with and transferred to the cleaning portion, with the heat transfer distance being zero. Furthermore, once the cleaning portion is heated, it is immediately used for cleaning, resulting in high efficiency, reduced heat waste, and improved heat utilization.

[0073] The heating unit includes a heat conductor 4 and a heating element 5. The heat conductor 4 is circumferentially arranged around the outer circumference of the rotating cylinder 3, and the heating element 5 is connected to the heat conductor 4. This design facilitates heat transfer through the heat conductor 4. On the one hand, the heating element 5 involves power supply issues, and the aforementioned design facilitates the arrangement of the heating element 5. On the other hand, the heat conductor 4 can be used to simply and efficiently transfer heat more comprehensively, thereby ensuring the heated area of ​​the cleaning unit. At the same time, it helps to reduce the number of installed heating elements 5 and avoid adding excessive weight.

[0074] The brush holder 1 is provided with a first opening 9 for detachably mounting the rotating cylinder 3, and a heating unit is provided in the first opening 9. This design does not affect the replacement of the rotating cylinder 3, and after replacing the rotating cylinder 3, there is no need to adjust the distance between the heating unit and the rotating cylinder 3. That is, the brush holder can be used directly after replacement, which greatly facilitates user use.

[0075] Preferably, Figure 1 、 2 As shown in Figures 3 and 4, the roller brush frame 1 is detachably connected to the upper cover 2. The heating unit is located on the lower side of the upper cover 2. After removing the upper cover 2, the heating unit can be seen. In addition, after removing the upper cover 2, the rotating cylinder 3 can also be removed in the vertical direction for cleaning or replacement. That is, the upper cover 2 also serves as a limit mounting member for the rotating cylinder 3. This design can greatly facilitate the production of the present invention and is also convenient for daily use.

[0076] A heating body of the heating part is provided on the side of the heating part that is in contact with the outer periphery of the rotating cylinder 3 .

[0077] The heating element comprises a continuous heat-conducting member 4 and a discontinuous heating member 5 arranged axially. The heat-conducting member 4 is located on the outside, while the heating member 5 is located on the inside. The heat-conducting member 4 isolates the heating member 5 from the rotating cylinder 3. This simplifies the arrangement and number of installed heating members 5. Furthermore, the heat-conducting member 4 isolates the heating member 5 from the rotating cylinder 3, protecting the heating member 5 and extending its service life.

[0078] The heating part is continuously arranged along the axial direction of the rotating cylinder 3. Such a design can make the cleaning part evenly heated, which is beneficial to the cleaning performance.

[0079] The device also includes a heat-insulating structure that ensures that most of the heat generated by the heating unit is transferred to the cleaning unit. For example, the heat-insulating structure can be provided as an insulating layer behind and around the heating element 5. This allows the heat from the heating element 5 to be primarily transferred to the front side, specifically to the heat conductor 4, which then transfers the heat to the cleaning unit. This design helps reduce waste and improve heat utilization.

[0080] The side of the heating unit facing the rotating cylinder 3 includes an arc-shaped structure arranged around the rotating cylinder 3. In this example, the heat conductor 4 is configured as an arc-shaped structure, that is, the heat conductor 4 is a concave arc-shaped plate. This design aligns the concave arc-shaped plate with the outer surface of the cleaning unit, facilitating smooth rotation of the cleaning unit and ensuring a good fit between the concave arc-shaped plate and the cleaning unit, thereby improving heat transfer efficiency.

[0081] In this example, no transition water tank 6 is provided. The above structure can be referred to in the attached Figure 1 、 2 , 4, and 5, Figure 2 、 4 , 5 and omitting the transition water tank 6 to constitute the other structures of this example.

[0082] In this example, the liquid outlet and the heating part share a frame, which has a front panel with liquid outlet holes 7 provided on the front panel. Each liquid outlet hole 7 is connected to the liquid supply assembly, and the heating part assembly is detachably connected to the frame.

[0083] Example 2:

[0084] The difference between Example 2 and Example 1 is that the heating part is clearance-matched with the outer periphery of the rotating cylinder 3. The technical effect of this arrangement is that, on the one hand, the rotational resistance of the rotating cylinder 3 is reduced, and on the other hand, wear is reduced. On the other hand, the squeezing of the cleaning part is reduced, which is beneficial to avoid the loss of cleaning liquid caused by the cleaning liquid in the cleaning part being squeezed out.

[0085] Example 3:

[0086] The difference between the third embodiment and the first embodiment is that the heating part and the outer periphery of the rotating cylinder 3 are both in contact and have a clearance fit. The advantage of this arrangement is that it provides great flexibility and can flexibly set the contact and clearance fit according to the characteristics of the cleaning part, thereby further optimizing the structure.

[0087] Example 4:

[0088] Compared with embodiments 1, 2 and 3, embodiment 4 differs in that a transition water tank 6 is added, and the heating part is used to heat the cleaning liquid supplied to the cleaning part. At this time, the heating part and the outer periphery of the rotating cylinder 3 are preferably clearance-matched.

[0089] When the transition water tank 6 is added, the structure is as follows: a heating part is provided in the circumferential direction of the outer periphery of the rotating cylinder 3, and the heating part is gap-matched with the outer periphery of the rotating cylinder 3. The heating part includes the transition water tank 6, and the heating element 5 of the heating part is located in the transition water tank 6. The transition water tank 6 is used to be connected to a water source. The heating element 5 is used to heat the cleaning liquid in the transition water tank 6. The heated cleaning liquid flows to the cleaning part, so that the cleaning part is also heated by the heat brought by the cleaning liquid.

[0090] The transition water tank 6 adopts a small capacity, and the capacity of the small capacity is smaller than the capacity of the water source.

[0091] Preferably, the small capacity is within six times, including six times, the volume of the cleaning liquid supply flow rate per unit time. The supply volume of the cleaning liquid per unit time is set according to the cleaning needs. Generally speaking, reaching or exceeding the supply volume is conducive to better exerting the cleaning performance. However, if the capacity of the transition water tank 6 is not limited, it will bring disadvantages, so the capacity of the transition water tank 6 is also very important, just as the present invention says "the transition water tank 6 adopts a small capacity, and the capacity of the small capacity is less than the capacity of the water source." After the above design, it can better connect the amount required for cleaning use and balance energy consumption. In addition, it is also more conducive to controlling the program to control the opening and closing of the heating element 5. This is because the larger the capacity of the transition water tank 6, the more difficult it is to control the stability of the working temperature during dynamic use. When the capacity of the transition water tank 6 is small, while being able to maintain the supply volume, then the balance point at this time is more conducive to balancing the three elements of energy consumption, temperature stability control, and cleaning performance.

[0092] The transition water tank 6 is provided with a labyrinth heating channel, which is used to allow the heating element 5 to quickly heat the clean liquid flowing through it in a short time. Figure 7 As shown, the labyrinth heating flow channel of the transition water tank 6 is configured as a V-shaped labyrinth heating flow channel. In addition, in order to better match the rotating cylinder 3, the overall shape of the transition water tank 6 is also roughly V-shaped.

[0093] In this example, if Figure 7As shown, the flow direction of the clean liquid in the V-shaped labyrinth heating channel is to flow in from the upper right end of the V-shaped labyrinth heating channel, and then flow out along the V-shape to the upper left end of the V-shaped labyrinth heating channel. After such a design, on the one hand, the flow distance is lengthened, so that the clean liquid has more time to absorb the heat generated by the heating element 5. On the other hand, the flow from bottom to top on the outlet side allows the heat to flow upward more easily, so the clean liquid can better carry away the heat generated by the heating element 5. In addition, because the V-shape causes the left and right channels to be closer, when the heating element 5 generates heat, the clean liquid in the top-down channel on the right side is preheated. Then, when it flows from bottom to top on the outlet side, the clean liquid can be heated to a higher temperature more quickly, shortening the heating time. In addition, the use of the V-shaped labyrinth heating channel makes the overall structure very compact. If it is necessary to further shorten the heating time, the heating element 5 can also be set simultaneously in the top-down channel on the right side.

[0094] The above design has the following technical effects: first, the cleaning liquid in the transition water tank 6 is used for the cleaning part after being heated, and there is no need for long-distance transportation, which greatly reduces waste. In addition, it also avoids the safety hazards caused by long-distance transportation. Second, according to the purpose of the invention, the amount of cleaning liquid in the transition water tank 6 is not set very much, so the heat generated by the heating element 5 is enough to heat the cleaning liquid in the transition water tank 6 in a short time, so that it can quickly enter the normal working state, and the working response is very fast. Third, when the work stops, there is not much cleaning liquid left in the transition water tank 6, so the wasted heat is very small. In addition, when When stopping work, it can be turned off in advance. For example, if the working time is set to 10 minutes, then when the 10-minute work stop time is reached, the heating element 5 is actively turned off in advance, so that the last heated cleaning liquid is also used to clean the cleaned surface, and the heated cleaning liquid will not be used up. Of course, other measures can also be adopted, such as turning off the heating element 5 in advance, but allowing the rotating cylinder 3 to continue to rotate, and the hot cleaning liquid remaining in the transition water tank 6 continues to be supplied, so that the rotating cylinder 3 can clean itself, thereby utilizing the heat of this part of the cleaning liquid remaining in the transition water tank 6. Therefore, taking this measure can also further reduce waste.

[0095] Embodiment 5:

[0096] like Figure 2 、 3 , 4, 5, 6, 7, Figure 7The middle arrow indicates the flow direction of the cleaning liquid. The difference between Example 5 and Example 4 is that not only a transition water tank 6 is added, but also a heating part is used to heat the cleaning part of the rotating cylinder 3. Specifically, in this example, the heating element 5 is circumferentially arranged around the outer periphery of the rotating cylinder 3. While heating the cleaning liquid, the heating element 5 also includes a heat conducting element 4. The heat conducting element 4 is circumferentially arranged around the outer periphery of the rotating cylinder 3. While heating the cleaning liquid, the heating element 5 also heats the cleaning part of the rotating cylinder 3 through the heat conducting element 4.

[0097] The technical effects of such a design are as follows: first, the heat generated in the front-to-back directions of the heating element 5 can be applied to the cleaning part more quickly, that is, the front side of the heating element 5 is the cleaning part, and the rear side of the heating element 5 is the cleaning liquid, so the heat generated in the front-to-back directions of the heating element 5 is more efficiently utilized. This is because the front side of the heating element 5 directly heats the cleaning part, and there is no need for the cleaning liquid in the transition water tank 6 to carry heat to heat the cleaning part, that is, one heat conversion is reduced, and the advantage of the front side of the heating element 5 directly heating the cleaning part is that it is also conducive to improving the compactness of the structure, and since the rear side of the heating element 5 cannot directly heat the cleaning part, the heat is carried by the cleaning liquid in the transition water tank 6 to superimpose the cleaning part that has been preheated by the front side of the heating element 5, so that the heat generated by the heating element 5 is more efficiently utilized. Since the heat is more efficiently utilized, it is very conducive to shortening the heating time, so that the working effect can be achieved in a short time. operating temperature; secondly, while achieving the goal of more efficient use of heat, it is conducive to further improving the compactness of the structure, thereby further reducing the thickness of the transition water tank 6; thirdly, when designing the V-shaped maze heating flow channel, the purpose of faster heating can be achieved by only setting a heating element 5 in the flow channel from bottom to top on the left side of the V-shaped maze heating flow channel, without setting heating elements 5 in the flow channels on both sides of the V-shaped maze heating flow channel, so that the overall structure is more optimized. At the same time, this also avoids the heat waste caused by setting heating elements 5 in the flow on both sides of the V-shaped maze heating flow channel. The reason is that if a heating element 5 is set in the flow channel from top to bottom on the right side of the V-shaped maze heating flow channel, the heat transfer of the heating element 5 to the right side will inevitably increase. Because it is restricted by the speed at which the clean liquid absorbs heat, it cannot be absorbed and taken away in time, resulting in heat loss. The above scheme avoids this situation.

[0098] In this example, if Figure 5 、 6As shown, a second opening 10 is provided on the side of the transition water tank 6 facing the rotating cylinder 3. The second opening 10 allows the heating element 5 to be exposed, thereby reducing the barrier between the heating element 5 and the heat-conducting element 4 and facilitating the heating element 5 to transfer heat through the heat-conducting element 4. This design allows the heating element 5 to be closer to the cleaning part, and also allows the transition water tank 6 to be closer to the cleaning part, so that the heated cleaning liquid can be transported to the cleaning part over a shorter distance, and the heated cleaning part and the heated cleaning liquid can meet more quickly, thereby minimizing heat loss and allowing the temperature of the cleaning part to be better maintained with a smaller heating power input, which further improves energy utilization and response performance.

[0099] In this example, if Figure 4 、 5 As shown in Figure 6, in order to output the heated cleaning liquid more evenly, a plurality of liquid outlet holes 7 are sequentially provided along the axial direction of the rotating cylinder 3. The liquid outlet holes 7 are connected to the outlet end of the V-shaped labyrinth heating channel through a plurality of connecting holes 8. Therefore, the plurality of liquid outlet holes 7 are located on the upper side of the heat conductor 4. The liquid inlet end 11 of the V-shaped labyrinth heating channel is connected to the water source through a pipeline, that is, it is connected to the cleaning liquid tank. A water pump can be provided to increase the delivery pressure of the cleaning liquid. It is also possible to timely shut down the heating element 5 by detecting the water level of the cleaning liquid tank and / or whether there is cleaning liquid in the pipeline, thereby achieving higher safety performance, such as anti-dry burning performance.

[0100] For the case of simultaneous heating, other solutions are also possible. For example, while the heating element 5 is heating the cleaning liquid, the cleaning part of the rotating cylinder 3 is directly heated by the heating element 5. For another example, while the heating element 5 is heating the cleaning liquid, the transition water tank 6 also becomes hot after the cleaning liquid is heated, so the cleaning part of the rotating cylinder 3 can be heated by the heated transition water tank 6.

[0101] Example 6:

[0102] The difference between the sixth embodiment and the fifth embodiment is that the sixth embodiment further comprises a scraper 12 for scraping the cleaning part, that is, scraping off the sewage and dirt on the cleaning part together, which are then sucked away by the suction port 13 near the scraper 12. This is also a working feature of the floor scrubber. Then in Example 6, along the rotation circumference of the rotating cylinder 3, the transition water tank 6 is located on the rear side of the scraper 12, that is, the cleaning part scrapes the dirt first, and then the transition water tank 6 supplies heat. The heat includes the heat for heating the cleaning part passing through the transition water tank 6 and the heat brought by the heated cleaning liquid when it falls from the liquid outlet 7 onto the cleaning part. In this way, the heat can be utilized more effectively without wasting heat on the contaminated part of the cleaning part (the contaminated part of the cleaning part). This is because the heat will be consumed after the cleaning part cleans the cleaned surface. Then, if the sewage is not removed in time, the part of the cleaning part where the sewage is located (the contaminated part of the cleaning part) will reabsorb the heat, and the contaminated part of the cleaning part is not conducive to cleaning. Therefore, through the above design, the heat is used more effectively, thereby further reducing waste.

[0103] Embodiment seven:

[0104] Compared with the above embodiments, the difference of the embodiment 7 is that there can be multiple heating parts, each heating part is arranged along the axial direction of the rotating cylinder 3, the axial length of each heating part is roughly equal to that of the cleaning part, and each heating part is also arranged in sequence along the circumference of the rotating cylinder 3. That is to say, compared with Figure 2 The structure of one heating part is shown in the figure. In embodiment 7, at least one heating part is added in sequence along the circumference of the rotating cylinder 3 to form a structure with two heating parts. Such a structure of embodiment 7 is conducive to reaching the required temperature more quickly, and if necessary, a higher temperature can be reached. However, the relatively large structure and high energy consumption have exceeded the requirements of ordinary cleaning. In some occasions where a higher temperature is required, embodiment 7 is more suitable.

[0105] Embodiment 8:

[0106] The difference between the eighth embodiment and the above embodiments is that it further includes a temperature sensor for detecting the temperature of the heating part and / or the temperature of the cleaning part and / or the temperature of the cleaning liquid supplied to the cleaning part and / or the temperature of the surface to be cleaned.

[0107] By setting up temperature sensors, the following technical effects can be achieved: on the one hand, it provides a structural basis for more intelligent control of heating, and combined with the control program, it helps to further fine-tune the control of energy consumption; on the other hand, it can further improve safety and provide an additional guarantee for safety.

[0108] Embodiment 9:

[0109] like Figures 8 to 15As shown, in this example, the transition water tank 6 is cancelled, and there is no concept of a water tank. The heating part has a main body 17 or a main body 17 with a flow channel. The main body 17 also serves as a heat conductor 4. The cleaning liquid flows into the flow channel from one end of the main body 17, that is, the liquid inlet joint 16 is connected to one end of the main body 17, and the liquid inlet joint 16 is communicated with the flow channel. The liquid inlet joint 16 is used to connect the liquid supply component, so that the overall volume of the heating part is significantly reduced, and the liquid is fed from one end, without the need for Figure 3 As shown, the liquid is fed from the liquid inlet end 11 at the upper middle position, which is also beneficial to reducing the size in the height direction. The above-mentioned measures are beneficial to reducing the volume of the roller brush, or freeing up more space to install other structures, such as Figure 10 As shown, since more installation space is freed up, the water pump 26 can also be integrated into the roller brush. In this example, the water pump 26 is located on the side where the liquid inlet connector 16 is located.

[0110] In this example, the main body 17 not only heats the cleaning liquid, but also, due to its inherent heat conduction, can be used to directly heat the cleaning portion. In other words, the main body 17 also serves as the heat conductor 4, thereby accelerating the heating of the cleaning portion. This design not only provides a fast response, but also, because the heat is used to heat the cleaning liquid and directly heat the cleaning portion through the main body 17, the heat is primarily used in the cleaning portion, resulting in high energy efficiency.

[0111] Embodiment 10:

[0112] Compared with the ninth embodiment, for example Figure 11 As shown, the liquid outlet is provided with a recess 22 extending along the axis of the rotating cylinder 3 on one side of the rotating cylinder 3, and a liquid outlet hole 7 is provided in the recess 22. After such design, the liquid outlet hole 7 is not easy to enter dirt, and the liquid outlet is kept smooth.

[0113] In some embodiments, as Figure 11 As shown, the rotating arrow indicates the rotation direction of the rotating cylinder 3, and the liquid outlet 7 is located on the side of the recess 22 on the side opposite to the rotation direction of the rotating cylinder 3. This design has a better anti-clogging performance. In addition, according to the above design, the cleaning part will not be tightly pressed against the liquid outlet 7, thereby facilitating smoother liquid discharge.

[0114] In each embodiment, the heating element 5 adopts an electric heating structure, such as PTC heating, film heating, printed heating body, etc. Any heating element 5 suitable for the present invention can be applied to the present invention.

[0115] When understanding the present invention, if necessary, the above structure can refer to other embodiments / appendices. Figure 1 And understand, no further elaboration here.

[0116] The above description is merely an illustrative embodiment of the present invention, and therefore any equivalent changes or modifications made according to the structure, features and principles described in the patent protection scope of the present invention are included in the patent protection scope of the present invention.
