Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rolling brush electric mop, scrubber, vacuum cleaner, sweeper and the like, in particular to a rolling brush and cleaning device. BACKGROUND

[0002] In the cleaning device such as rolling brush electric mop, scrubber, vacuum cleaner, sweeper, the rolling brush is one of the important technical means to improve the cleaning performance, and the general working principle of the rolling brush is that the rolling brush is in rotary contact with the cleaned surface to clean the cleaned surface through the contact.

[0003] In order to improve the cleaning performance, there is a scheme of spraying cleaning liquid such as cleaning agent, water and the like on the rolling brush or before and after the rolling brush, so as to improve the cleaning performance by wetting the rolling brush or the cleaned surface. In addition, in order to further improve the cleaning performance, there is a scheme of heating the cleaning liquid, that is, using hot cleaning liquid to improve the cleaning performance. However, at present, there are many different schemes for how to generate and supply the hot cleaning liquid, which can be generally divided into two kinds. One is to heat the cleaning liquid in the liquid storage tank by using electric heating or chemical energy, and the liquid storage tank is connected with the rolling brush through a pipeline. The delivered cleaning liquid is sprayed on the rolling brush or the cleaned surface. There are generally two kinds of spraying on the rolling brush, one is spraying on the upper side of the rolling brush outside, and the other is flowing from the inside of the rolling brush and then seeping out from the cleaning part of the rolling brush. Such a scheme has a long delivery distance, high energy consumption and slow response. In addition, the problem of high-pressure and high-temperature storage after heating of the liquid storage tank is a big problem, and how to ensure safety is a big problem. The other is a scheme specially proposed by the present applicant, that is, directly heating the rolling brush. After the heated rolling brush meets the cleaning liquid, the cleaning liquid is indirectly heated, so as to obtain the hot cleaning effect. Compared with the original technology, the delivery path of this scheme is further shortened, which is beneficial to energy saving and improving the response performance, and the safety problem is also well solved. In addition, by setting an electric connection structure, the battery does not need to be arranged at both ends of the cylinder body or in the cylinder body of the rolling brush, but is supplied with power by the power supply of the cleaning device. On the one hand, the power supply capacity is increased, and the endurance is ensured. On the other hand, the cost of replacing the rolling brush is reduced, so that the rolling brush proposed by the present applicant can be practically applied to life, rather than being theoretical. However, even though the rolling brush proposed by the present applicant has the above-mentioned many advantages, the present applicant still hopes to further improve the energy utilization efficiency and response performance, which is of great significance to reducing the size of the battery, reducing the cost and improving the practicability.

[0004] Therefore, the present applicant continues to conduct in-depth research, and through the unremitting efforts of the present applicant, the present applicant will propose a rolling brush in the present application, which can further improve the energy utilization efficiency and response performance.

The embodiments disclosed in the following description are only examples of the present application and are not intended to limit the scope of the present application. The principles of the present application defined in the following description can be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the present application.

[0035] The present application will be further described in detail below. The present application provides a cleaning device, which comprises the rolling brush as shown in

[0036] Fig. 1.

[0037] The present application provides a cleaning device, which comprises the rolling brush as shown in

[0038] The present application provides a cleaning device, which comprises the rolling brush as shown in Figure 1 Fig. 1.

[0039] ​The cleaning device refers to a household cleaning device or a small cleaning device, which is also a feature of the roll brush, and the overall structure size is required to be small, which can be applied to a small cleaning device.

[0040] The roll brush includes a rotating cylinder 3. Of course, the rotating cylinder 3 can be multiple, such as two, three, etc. However, regardless of the number, the scheme can be adjusted or simply copied. The application also points out that when there are multiple rotating cylinders 3, at least one rotating cylinder 3 is provided with a heating part. When multiple rotating cylinders 3 need to be provided with a heating part, it can be ingeniously arranged as follows: a heating part is arranged between two adjacent rotating cylinders 3, that is, the two adjacent rotating cylinders 3 share a heating part. At this time, the heating part can transfer heat to the corresponding rotating cylinder 3 on both sides, such as two heating parts 5 on both sides, or the transition water tank 6 transfers heat to the corresponding rotating cylinder 3 on both sides after being heated.

[0041] 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 requirement of the cleaned surface. By using the scheme of the application, the original rotating cylinder 3 structure does not need to be modified, and the existing rotating cylinder 3 can be used. The cost of replacing and using the rotating cylinder 3 of the user is almost not increased.

[0042] The use of cleaning liquid can have multiple situations, such as using other equipment to sprinkle on the cleaned surface, such as manually sprinkling water, the heated cleaning part encounters the wet cleaned surface, and good cleaning effect can also be achieved. At this time, the object of heating is the cleaning part. For example, the cleaning device is provided with other liquid supply structure, which sprays cleaning liquid on the cleaning part, and the cleaning part with cleaning liquid is heated and used. If the cleaned surface is dry, but under the action of the heated wet cleaning part, good cleaning effect can also be achieved. For example, as described in the following embodiment, the scheme including the transition water tank, and the like. Here, it is not listed one by one.

[0043] The water or water-related description described in the application does not only refer to water, but also refers to the commonly used term, such as the cleaning liquid tank is also commonly called the water tank. The water here refers to the cleaning liquid, which can be water, a mixture of water and cleaning agent, or a mixture of water and disinfectant.

[0044] The following examples of multiple embodiments further illustrate the roll brush of the application:

[0045] Embodiment one:

[0046] The brush roller comprises a rotating cylinder 3, a heating portion is arranged on the outer periphery of the rotating cylinder 3 in the circumferential direction, the heating portion is attached to the outer periphery of the rotating cylinder 3, and the heating portion is used for heating a cleaning portion of the rotating cylinder 3. In this way, the heat generated by the heating portion is directly attached to and transmitted to the cleaning portion, the distance of heat transmission is zero, and the cleaning portion is immediately used for cleaning after being heated, the use efficiency is high, the waste of heat is reduced, and the effective utilization rate of heat is improved.

[0047] The heating portion comprises a heat-conducting member 4 and a heating member 5, the heat-conducting member 4 is arranged on the outer periphery of the rotating cylinder 3 in the circumferential direction, and the heating member 5 is connected to the heat-conducting member 4. In this way, the heat can be conveniently transmitted through the heat-conducting member 4, on the one hand, the heating member 5 involves power supply problems, and the structure of the heating member 5 can be conveniently arranged according to the foregoing design, and on the other hand, the heat can be simply and efficiently transmitted more comprehensively through the heat-conducting member 4, thereby being beneficial to guarantee the heating area of the cleaning portion and simultaneously being beneficial to reduce the installation quantity of the heating member 5 and avoid increasing excessive weight.

[0048] The brush roller further comprises a brush roller frame 1, the brush roller frame 1 is provided with a first opening 9 for detachably mounting the rotating cylinder 3, and the heating portion is arranged in the first opening 9. In this way, the replacement of the rotating cylinder 3 is not affected, and after the rotating cylinder 3 is replaced, the distance between the heating portion and the rotating cylinder 3 no longer needs to be adjusted, that is, the brush roller can be directly used after replacement, thereby greatly facilitating the use of users.

[0049] Preferably, as shown in Figure 1 , 2 , the brush roller frame 1 is detachably connected with an upper cover 2, the heating portion is located on the lower side of the upper cover 2, the heating portion can be seen after the upper cover 2 is removed, and in addition, the rotating cylinder 3 can be removed along the up-down direction for cleaning or replacement after the upper cover 2 is removed, that is, the upper cover 2 simultaneously serves as a limiting mounting piece of the rotating cylinder 3. In this way, the production and manufacture of the brush roller can be greatly facilitated, and the daily use of users can be facilitated.

[0050] The side of the heating portion, which is used for being attached to the outer periphery of the rotating cylinder 3, is provided with a heating body of the heating portion.

[0051] The heating body comprises a continuous heat-conducting member 4 arranged in the axial direction and a non-continuous heating member 5, the heat-conducting member 4 is on the outer side, the heating member 5 is on the inner side, and the heat-conducting member 4 separates the heating member 5 from the rotating cylinder 3. In this way, on the one hand, the setting and installation quantity of the heating member 5 are simplified, and on the other hand, the heat-conducting member 4 separates the heating member 5 from the rotating cylinder 3, thereby being beneficial to protect the heating member 5 and prolong the service life.

[0052] The heating portion is continuously arranged along the axial direction of the rotating cylinder 3. In this way, the cleaning portion can be uniformly heated, and the cleaning performance is improved.

[0053] Further, a heat preservation structure is arranged to make the heat generated by the heating part to be mainly transferred to the cleaning part. The heat preservation structure is, for example, a heat insulation layer arranged at the rear and around the heating element 5, so that the heat of the heating element 5 is mainly transferred to the front side, i.e. to the heat conducting element 4, and then to the cleaning part. This design is beneficial to reduce waste and improve heat utilization.

[0054] The heating part is arranged to have an arc structure around the rotation direction of the rotating cylinder 3. In this embodiment, the heat conducting element 4 is arranged to have an arc structure, i.e. the heat conducting element 4 is a concave arc plate. After this design, the concave arc plate matches the outer circumferential surface of the cleaning part, which is beneficial to the smooth rotation of the cleaning part and the good adhesion of the concave arc plate to the cleaning part, thereby improving the heat transfer efficiency.

[0055] In this embodiment, the transition water tank 6 is not arranged, and other structures in which the transition water tank 6 is omitted in the above structure and shown in Figs. 4, 5 can be used in this embodiment. Figure 1 2 Figure 2 4

[0056] Embodiment Two:

[0057] Compared with Embodiment One, the difference of Embodiment Two is that the heating part is arranged to have a gap with the outer circumference of the rotating cylinder 3. The technical effect of this design is that, on the one hand, the rotation resistance of the rotating cylinder 3 is reduced, on the other hand, the abrasion is reduced, and on the other hand, the extrusion to the cleaning part is reduced, which is beneficial to avoid the loss of the cleaning liquid in the cleaning part.

[0058] Embodiment Three:

[0059] Compared with Embodiment One, the difference of Embodiment Three is that the heating part is arranged to have both abutment and gap with the outer circumference of the rotating cylinder 3. The advantage of this design is that great flexibility is provided, and the abutment and gap can be flexibly arranged according to the characteristics of the cleaning part, thereby optimizing the structure.

[0060] Embodiment Four:

[0061] Compared with Embodiments One, Two and Three, the difference of Embodiment Four is that only the transition water tank 6 is arranged, and the heating part is used to heat the cleaning liquid supplied to the cleaning part. At this time, the heating part is preferably arranged to have a gap with the outer circumference of the rotating cylinder 3.

[0062] ​​​​When the transition water tank 6 is added, the structure is that a heating part is arranged in the circumferential direction of the outer periphery of the rotating cylinder 3, the heating part is matched with the gap of the outer periphery of the rotating cylinder 3, the heating part comprises the transition water tank 6, the heating element 5 of the heating part is located in the transition water tank 6, the transition water tank 6 is used for connecting with a water source, the heating element 5 is used for heating the cleaning liquid in the transition water tank 6, and the heated cleaning liquid flows to the cleaning part, so that the cleaning part is also heated by the heat taken by the cleaning liquid.

[0063] 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.

[0064] Preferably, the small capacity is within six times of the volume of the supply flow of the cleaning liquid per unit time, including six times. The supply amount of the cleaning liquid per unit time is set according to the cleaning requirement, and generally, reaching or exceeding the supply amount is beneficial to better cleaning performance, but if the capacity of the transition water tank 6 is not limited, disadvantages will be caused, so the capacity of the transition water tank 6 is also important, as the application says that 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 foregoing design, the required amount for cleaning use can be better connected, the energy consumption can be balanced, and the program control of opening and closing the heating element 5 can be more beneficial to control, because the larger the capacity of the transition water tank 6 is, the more difficult it is to control the stability of the working temperature in the dynamic use process, when the capacity of the transition water tank 6 is small and the supply amount is maintained, the balance point is more beneficial to balance the energy consumption, temperature stability control and cleaning performance.

[0065] The transition water tank 6 is provided with a labyrinth heating flow channel, and the labyrinth heating flow channel is used for rapidly heating the cleaning liquid flowing therethrough in a short time. Figure 7 As shown in the figure, a V-shaped labyrinth heating flow channel is arranged. Figure 4 , 5 As shown by 6, because the V-shaped labyrinth heating flow channel is arranged, and in order to better match the rotating cylinder 3, the overall shape of the transition water tank 6 is also roughly V-shaped.

[0066] As shown in the figure, a V-shaped labyrinth heating flow channel is arranged. Figure 7As shown, the flow direction of the cleaning liquid in the V-shaped labyrinth heating flow channel is from the upper right end of the V-shaped labyrinth heating flow channel, and then flows along the V-shaped to the upper left end of the V-shaped labyrinth heating flow channel. After this design, on the one hand, the flow distance is lengthened, so that the cleaning liquid has more time to absorb the heat generated by the heating element 5. On the other hand, the flow from the bottom to the top at the outlet side makes the cleaning liquid better carry away the heat generated by the heating element 5, because the heat is more likely to flow upwards. In addition, due to the V-shaped structure, the left and right flow channels are relatively close, so that the cleaning liquid in the right upward flow channel is preheated when the heating element 5 generates heat, and then flows from the bottom to the top at the outlet side, which can heat the cleaning liquid to a higher temperature more quickly, thereby shortening the heating time. In addition, the use of the V-shaped labyrinth heating flow channel makes the overall structure very compact. If it is necessary to further shorten the heating time, the heating element 5 can also be arranged in the right upward flow channel.

[0067] After the above design, the following technical effects are achieved: First, the cleaning liquid in the transition water tank 6 is used for cleaning after being heated, without the need for long-distance transportation, greatly reducing waste, and avoiding safety hazards caused by long-distance transportation. Second, as known from the purpose of the application, the amount of cleaning liquid in the transition water tank 6 will not be set too much, so the heat generated by the heating element 5 is sufficient to heat the cleaning liquid in the transition water tank 6 in a short time, thereby quickly entering the normal working state, with very fast working response. Third, when the work is stopped, the cleaning liquid remaining in the transition water tank 6 is not much, so the wasted heat is very little. In addition, when the work is stopped, the heating element 5 can be closed in advance, for example, if the working time is set to 10 minutes, the heating element 5 is actively closed in advance when the 10-minute working stop time is reached, so that the last heated cleaning liquid is also used for cleaning the surface being cleaned, rather than the heated cleaning liquid not being used up. Of course, other measures can also be taken, such as closing the heating element 5 in advance, but the rotating cylinder 3 continues 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 be cleaned in this way, thereby utilizing the heat of the cleaning liquid remaining in the transition water tank 6. Therefore, this measure can also further reduce waste.

[0068] Example Five:

[0069] As shown in Figure 2 , 3 , 4, 5, 6, 7, Figure 7The middle arrow indicates the flow direction of the cleaning liquid. Embodiment five is different from embodiment four in that not only the transition water tank 6 is included, but also the cleaning part of the rotating cylinder 3 is heated by the heating part. In this embodiment, the heating part 5 is arranged around the circumference of the outer periphery of the rotating cylinder 3. The heating part 5 not only heats the cleaning liquid, but also heats the cleaning part of the rotating cylinder 3 through the heat conduction part 4 arranged around the circumference of the outer periphery of the rotating cylinder 3.

[0070] The design has the following technical effects. First, the heat generated by the heating part 5 in the front-rear direction can be more quickly applied to the cleaning part. That is, the front side of the heating part 5 is the cleaning part, and the rear side of the heating part 5 is the cleaning liquid. The heat generated by the heating part 5 in the front-rear direction is more efficiently utilized. This is because the front side of the heating part 5 directly heats the cleaning part, and the cleaning liquid in the transition water tank 6 does not need to carry heat to heat the cleaning part. That is, one heat conversion is reduced. The front side of the heating part 5 directly heats the cleaning part, which is also beneficial to improve the compactness of the structure. The rear side of the heating part 5 cannot directly heat the cleaning part, so the cleaning liquid in the transition water tank 6 carries heat to superimpose the cleaning part that has been preheated by the front side of the heating part 5. Thus, the heat generated by the heating part 5 is more efficiently utilized. The heat is more efficiently utilized, which is very beneficial to shorten the heating time and reach the working temperature in a short period of time. Second, while achieving the purpose of more efficient utilization of heat, the compactness of the structure is further improved, thereby further reducing the thickness of the transition water tank 6. Third, when designing the V-shaped labyrinth heating flow channel, the heating part 5 arranged in the left side of the V-shaped labyrinth heating flow channel from bottom to top can achieve the purpose of faster heating, without the need to arrange the heating part 5 in the flow channels on both sides of the V-shaped labyrinth heating flow channel. This makes the overall structure more optimized. In addition, this design avoids the waste of heat caused by arranging the heating part 5 in the flow channels on both sides of the V-shaped labyrinth heating flow channel. The reason is that if the heating part 5 is arranged in the right side of the V-shaped labyrinth heating flow channel from top to bottom, the heat transfer of the heating part 5 to the right side will be increased. However, due to the speed of heat absorption of the cleaning liquid, the heat cannot be absorbed and removed in time, resulting in heat loss. The above-mentioned solution avoids this situation.

[0071] In this embodiment, as shown in FIG. 6, the heating part 5 is arranged in the left side of the V-shaped labyrinth heating flow channel from bottom to top. Figure 5 , 6As shown, the transition water tank 6 has a second opening 10 on the side facing the rotating cylinder 3, allowing the heating element 5 to be exposed. This reduces the obstruction between the heating element 5 and the heat-conducting element 4, making it easier for 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 section, and also allows the transition water tank 6 to be closer to the cleaning section. This enables the heated cleaning liquid to be transported to the cleaning section over a shorter distance, and also allows the heated cleaning section and the heated cleaning liquid to meet more quickly, thereby minimizing heat loss. This allows for better maintenance of the temperature of the cleaning section with a smaller input heating power, which in turn improves energy utilization and response performance.

[0072] In this example, as Figure 4 , 5 As shown in Figure 6, to ensure a more uniform output of the heated cleaning liquid, multiple water outlets 7 are sequentially arranged along the axial direction of the rotating cylinder 3. These outlets 7 are connected to the outlet end of the V-shaped labyrinth heating channel via multiple connecting holes 8. Therefore, the multiple water outlets 7 are located on the upper side of the heat-conducting component 4. The water inlet 11 of the V-shaped labyrinth heating channel is connected to a water source via a pipeline, i.e., connected to the cleaning liquid tank. A water pump can be installed to increase the delivery pressure of the cleaning liquid. Alternatively, the heating component 5 can be shut off promptly by detecting the water level in the cleaning liquid tank and / or the presence of cleaning liquid in the pipeline, thereby achieving higher safety performance, such as anti-dry-burning performance.

[0073] Other solutions are also possible for simultaneous heating. For example, while heating the cleaning liquid, the heating element 5 can directly heat the cleaning part of the rotating cylinder 3. Or, while heating the cleaning liquid, the transition water tank 6 can also be heated after the cleaning liquid is heated, so the cleaning part of the rotating cylinder 3 can be heated through the heated transition water tank 6.

[0074] Example 6:

[0075] The embodiment six is different from the embodiment five in that it further comprises a squeegee 12 which squeegethe cleaning part, that is, squeegethe sewage and dirt on the cleaning part, and then the sewage and dirt are sucked by the suction port 13 near the squeegee 12, which is also the working feature of the scrubber. In the embodiment six, the transition water tank 6 is located at the rear side of the squeegee 12 along the circumferential direction of the rotating cylinder 3, that is, the cleaning part is squeeget first, and then the heat is supplied by the transition water tank 6, which includes the heat of the cleaning part passing through the transition water tank 6 and the heat taken away by the cleaning liquid falling on the cleaning part from the water outlet hole 7, so that the heat can be more effectively utilized without wasting the heat on the contaminated part of the cleaning part, because the heat is consumed after the cleaning part cleans the surface to be cleaned, and if the sewage is not removed in time, the part of the cleaning part where the sewage is located will reabsorb the heat, and the contaminated part of the cleaning part is not conducive to cleaning, so the above design makes the heat more effectively used, thereby further reducing the waste.

[0076] Embodiment seven:

[0077] The embodiment seven is different from the above-mentioned embodiments in that the heating part can be multiple, each heating part is arranged along the axial direction of the rotating cylinder 3, the axial length of each heating part is substantially equal to that of the cleaning part, and each heating part is sequentially arranged along the circumferential direction of the rotating cylinder 3, that is, compared with the structure of one heating part shown in the above-mentioned embodiments, the embodiment seven sequentially increases at least one heating part along the circumferential direction of the rotating cylinder 3 to form a structure of two heating parts. Figure 2 The structure of the embodiment seven is beneficial to more quickly reaching the required temperature, and if necessary, a higher temperature can also be reached, but the relative structure is larger and the energy consumption is higher, which has exceeded the requirement of ordinary cleaning, and the embodiment seven is more suitable for some occasions which require a higher temperature.

[0078] Embodiment eight:

[0079] The embodiment eight is different from the above-mentioned embodiments in that it further comprises a temperature sensor which is used to detect 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.

[0080] By arranging the temperature sensor, the technical effect that can be achieved is that on the one hand, it provides a structural basis for more intelligent control of heating, which helps the further fine control of energy consumption in combination with the control program, and on the other hand, it can further improve the safety, which provides an additional guarantee for safety.

[0081] For each embodiment, the heating element 5 adopts an electric heating structure, such as PTC heating, and any heating element 5 suitable for the present application can be applied to the present application.

[0082] In understanding the present application, the foregoing description can be read in conjunction with other parts of the detailed description and specific embodiments disclosed herein. Figure 1 It will be understood that, in the event of any discrepancy between what is described in this detailed description and the drawings, the drawings will be understood to be correct.

[0083] The foregoing is considered as illustrative only of the principles of the application. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the application to the exact construction and operation described. Accordingly, all such variations are intended to be included within the scope of the present application as defined in the claims.
