Description

Technical Field

[0001] The 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 cleaning device with a roller brush. 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, the power supply capacity is increased and the battery life is guaranteed. On the other hand, the cost of replacing the roller brush is reduced, 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 battery life and heating response performance of the cleaning device, which is of great significance for reducing the size of the battery pack and improving practicality.

[0004] Therefore, the applicant continues to conduct in-depth research and will propose a cleaning device with a roller brush in the present disclosure, which can further improve the endurance and heating response performance of the cleaning device. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the prior art and propose a cleaning device with a roller brush, which can further improve the endurance and heating response performance of the cleaning device.

[0006] Compared with the prior art, the present invention proposes a cleaning device with a roller brush, comprising a clean water tank and a roller brush, the clean water tank being used to supply cleaning liquid, the cleaning liquid in the clean water tank being heated by electric heating and / or chemical reaction to obtain cleaning liquid of a first temperature, the electric heating component of the electric heating being supplied with electric energy by AC power and / or a battery pack powered by AC power; the device also comprises a heating part electrically connected to the battery pack, the heating part being in contact with and / or having a gap fit with the outer periphery of the rotating cylinder, the heating part being used to heat the cleaning part of the rotating cylinder and / or the cleaning liquid supplied to the cleaning part; the first temperature can be set by the user or not.

[0007] The first temperature may be set by the user or may not be set by the user. The first temperature may be a temperature threshold or a temperature range.

[0008] The cleaning liquid in the clean water tank can be a cleaning liquid with a first temperature poured in from an external water tank. For example, the base station is provided with a heating water tank, and the heating water tank is provided with an electric heating component. The cleaning liquid is first heated in the heating water tank (supplied by AC power and / or a battery pack powered by AC power). After reaching the first temperature or higher than the first temperature, the cleaning liquid is pumped into the clean water tank.

[0009] Alternatively, an electric heating component may be provided in the clean water tank, and the mains electricity and / or a battery pack powered by the mains electricity may be used to supply electric energy to the electric heating component, thereby directly heating the clean liquid in the clean water tank.

[0010] Alternatively, a heating element that reacts with water may be added into the clean water tank to obtain the clean liquid at the first temperature through heating by a chemical reaction.

[0011] It can also be any combination of the above-mentioned technical means. In short, in the solution disclosed in the present invention, the energy for heating the cleaning liquid to the first temperature does not rely on the battery pack, but when the battery pack is in charging conditions, the battery pack can be used for heating. However, in essence, in the solution disclosed in the present invention, the energy for heating the cleaning liquid to the first temperature comes from external energy supply.

[0012] After adopting the above structure, compared with the prior art, the present invention has the following advantages:

[0013] Since the cleaning liquid at the first temperature is supplied with electrical energy by the mains and / or a battery pack powered by the mains and / or energy is supplied by chemical reactions, when a higher temperature is needed during cleaning, the heating part can be turned on, and the electrical energy required for the cleaning liquid to reach a higher temperature is relatively reduced, which is beneficial to improving battery life. From another perspective, the battery pack can be smaller while maintaining the same working time.

[0014] Since the cleaning liquid already has the first temperature, the time to reach a higher temperature can be reduced, which is beneficial to further improve the heating response performance of the cleaning device.

[0015] Further combined with the following structure: Since the present disclosure provides a heating part in the circumference of the outer periphery of the rotating cylinder, the heating part is in contact with and / or has a gap with the outer periphery of the rotating cylinder, and the heating part is used to heat the cleaning part of the rotating cylinder and / or the cleaning liquid supplied to the cleaning part, the heat generated by the heating part 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 wet cleaning part heats the cleaning liquid in the cleaning part when passing through the cleaning part, and 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. With this design, the heated cleaning liquid immediately falls on the cleaning part to participate in the subsequent cleaning work, and the heat utilization rate is very high with little waste, which is conducive to further reducing the power consumption of the battery pack and can further improve the endurance of the cleaning device.

[0016] At the same time, since the heating part is in contact with and / or has a gap fit 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, so the amount of heat required to reach a certain temperature during heating is less, which can greatly improve the response performance. In addition, the cleaning liquid already has a first temperature. Therefore, after the heating part is turned on, in the present disclosure, the cleaning part of the rotating cylinder and / or the cleaning liquid supplied to the cleaning part can quickly reach the required working temperature, thereby greatly improving the response performance.

[0017] In summary, the present disclosure can further improve the endurance and heating response performance of the cleaning device.

[0018] In addition, since the cleaning liquid reaches a higher temperature through the heating part, the requirement for the first temperature is reduced. The solution disclosed in the present invention is conducive to avoiding the high-pressure and high-heat storage problem caused by excessive temperature in the clean water tank (liquid storage tank), thereby improving the safety of use.

DETAILED DESCRIPTION

[0062] 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.

[0063] The present invention will be further described in detail below:

[0064] The present disclosure provides a cleaning device including a roller brush. Examples of cleaning devices include electric mops with roller brushes, vacuum cleaner nozzles, sweepers, and floor scrubbers. 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, which requires a relatively small overall size for its applicability to small cleaning devices.

[0065] like Figure 41 、 42 As shown, the present disclosure proposes a cleaning device with a roller brush, which includes a clean water tank 64 and a roller brush. The clean water tank 64 is used to supply cleaning liquid. The cleaning liquid in the clean water tank 64 is heated by electric heating and / or chemical reaction to obtain a cleaning liquid of a first temperature. The electric heating component of the electric heating is supplied with electric energy by AC power and / or a battery pack powered by AC power; it also includes a heating part electrically connected to the battery pack, the heating part is in contact with and / or has a gap fit with the outer periphery of the rotating cylinder 3, and the heating part is used to heat the cleaning part of the rotating cylinder 3 and / or the cleaning liquid supplied to the cleaning part; the first temperature can be set by the user or not.

[0066] like Figure 41 The figure shows a three-dimensional schematic diagram of the main body 62 of a floor scrubber placed on a base station 63. In the prior art, when the main body 62 of the floor scrubber is placed on the base station 63, functions such as charging and / or self-cleaning and / or automatic liquid addition of the floor scrubber can be realized. In the present disclosure, for the sake of simplicity, the existing functions of the floor scrubber and the base station are not elaborated, and other cleaning devices can also refer to the technical solution ideas of the present disclosure to specifically set the relevant structures.

[0067] Depend on Figure 42 As shown, the clean water tank 64 is provided with an electrode 65 and a heater plate 66. The heater plate 66 is conventional, and may be a PTC heater plate, a graphene heater plate, or the like. The clean water tank 64 is mounted on the main body 62 and electrically connected to an external power supply circuit via the electrode 65. This power supply circuit is generally electrically connected to the mains. That is, when the main body 62 is placed on the base station 63, the main body 62 is powered by the power supply of the base station 63, which in turn is powered by the mains. In this way, the main body 62 is connected to the mains through the base station 63, and the power supply circuit is powered by the mains, allowing the heater plate 66 to heat the clean water tank 64 according to a set temperature. The set temperature utilizes the control unit feature of existing intelligent cleaning devices. Consider adding a temperature sensor component, which feeds back a signal to the control unit. The control unit controls the power supply circuit to heat the clean water tank 64 to reach the set temperature. Because of the control unit, the first temperature can be set as needed. The power supply circuit is a conventional setting and will not be elaborated on here.

[0068] In some embodiments, a reservation module is also included, which allows the user to reserve the time for the cleaning liquid to reach the first temperature. The reservation module is a timing module. Since existing intelligent cleaning devices all have control units, the timing function can be realized by using the control unit. For example, the control unit uses a single-chip microcomputer with a timing function in the prior art. When the user-set time is reached, the control unit can control the power supply circuit to connect to the mains to heat the clean water tank 64. This can match the user's usage time on time and as needed, rather than long-term power-on heating of the clean water tank 64. After such a design, energy consumption can also be reduced at the same time. The specific method of reservation can be to set it directly on the cleaning device by means of touch, buttons, etc., or it can be set remotely by mobile phone APP, etc. All setting technical means applicable to the present disclosure are applicable.

[0069] In some embodiments, a switch module is also included, which allows the user to control whether the heating unit is turned on when cleaning the surface to be cleaned. For example, as described below: During the cleaning process, for example, the user manually turns on the heating unit, and at the same time, the rotating cylinder 3 rotates. The liquid outlet may or may not spray liquid. Generally speaking, spraying liquid is required, so that the hot and wet cleaning unit has a better cleaning effect on the surface to be cleaned. Manual activation can adopt common switch structures such as touch and mechanical switches. With this design, the user can turn on the heating unit according to their own needs instead of keeping it on all the time, which can further improve battery life.

[0070] In some embodiments, the system further includes a prompt module for indicating whether the clean water tank is ready, where the readiness of the clean water tank refers to whether the clean water tank has reached the first temperature. The prompt module may be provided by conventional audio and visual means such as an indicator light or a speaker. This design allows the user to more easily determine whether the clean water tank is ready, thereby improving the user experience.

[0071] 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.

[0072] 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.

[0073] 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. The liquid supply structure 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.

[0074] 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.

[0075] The present disclosure heats the outer periphery of the rotating cylinder 3 by fitting the heating unit against the outer periphery of the rotating cylinder 3. This outer periphery is the cleaning portion. Therefore, the heat generated by the heating unit can be transferred to the cleaning portion as quickly as possible. Consequently, less heat is required to reach a certain temperature during heating, which greatly improves responsiveness. In other words, once the heating unit is turned on, the cleaning portion of the rotating cylinder 3 in the present disclosure will quickly reach the required operating temperature, thereby significantly improving responsiveness.

[0076] In summary, the present disclosure can further improve energy utilization efficiency and response performance.

[0077] In some embodiments, a cleaning program can be added to the original control unit of the cleaning device. In this cleaning program, the heating unit is used to heat the cleaning unit of the rotating cylinder 3 and / or the cleaning liquid supplied to the cleaning unit to clean the surface being cleaned. During the cleaning program, for example, the user manually turns on the heating unit while the rotating cylinder 3 rotates. The liquid outlet may or may not spray liquid. Generally, spraying liquid is required. In this way, the heated and moistened cleaning unit has a better cleaning effect on the surface being cleaned. In addition, as can be seen from the above analysis, the present disclosure can further improve energy efficiency and response performance.

[0078] In some embodiments, for example, Figure 23 As shown, the present disclosure proposes a liquid outlet portion, including a main body extending along the axial direction of the rotating cylinder 3, the main body is provided with a liquid outlet channel 14 arranged along the axial direction, and the starting point and end point of the liquid outlet channel 14 along the axial direction respectively serve as the two ends of the liquid outlet channel 14, and the main body is located on one side of the rotating cylinder 3 and is provided with a plurality of liquid outlet holes 7 arranged in sequence along the liquid outlet channel 14, each liquid outlet hole 7 is respectively connected to the liquid outlet channel 14, and one of the two ends serves as a liquid inlet 15, and from the liquid inlet 15 to the other end of the liquid outlet channel 14, the size of each liquid outlet hole 7 gradually increases along the axial direction.

[0079] After adopting the above structure, the present invention has the following advantages: since the size of each liquid outlet hole 7 gradually increases along the axial direction of the rotating cylinder 3 from the liquid inlet of the liquid outlet channel 14 to the other end of the liquid outlet channel 14, when water is discharged, since the water pressure is high on the side close to the liquid inlet 15, the flow rate of the liquid outlet hole 7 close to the liquid inlet 15 is fast, then when the liquid outlet hole 7 close to the liquid inlet 15 becomes smaller, since the flow cross-section becomes smaller, although the flow rate is fast, its water output is still smaller than that of the original structure, and although the flow rate of the liquid outlet hole 7 slightly farther away is relatively slow, its water output is larger than that of the original structure due to the enlargement of the hole, then based on the above scheme, the degree of wetting of the cleaning part of the rotating cylinder 3 is more uniform, so while adopting the technical scheme of liquid inlet at one of the two ends of the liquid outlet channel, it is also beneficial to make the degree of wetting of the cleaning part of the rotating cylinder 3 more uniform, and due to the simple structure, it provides a favorable prerequisite for reducing the volume of the roller brush.

[0080] The present disclosure also proposes a liquid outlet, compared with the above liquid outlet, such as Figure 24 As shown, the characteristic is that the intervals between adjacent liquid outlet holes 7 gradually decrease along the axis direction.

[0081] After adopting the above structure, the present disclosure has the following advantages: since the intervals between adjacent liquid outlet holes 7 gradually decrease along the axial direction from the liquid inlet of the liquid outlet channel 14 to the other end of the liquid outlet channel 14, the liquid outlet holes 7 on the side close to the liquid inlet 7 are distributed more sparsely, while the liquid outlet holes 7 farther away from the liquid inlet are distributed more densely, so the degree of wetting of the cleaning part of the rotating cylinder 3 can be more uniform. Therefore, while adopting the technical solution of liquid introduction at one of the two ends of the liquid outlet channel, it is also beneficial to make the wetting degree of the cleaning part of the rotating cylinder 3 more uniform. Due to the simple structure, it provides a favorable prerequisite for reducing the volume of the roller brush.

[0082] 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 phrase "the body is provided with a liquid outlet channel 14 arranged along the axis" does not necessarily require that the liquid outlet channel 14 must be arranged parallel to the axis. Rather, it requires that each liquid outlet hole 7 can cover the cleaning portion of the rotating cylinder 3. This requires that the liquid outlet channel 14 must be able to transport liquid to each liquid outlet hole 7, hence the phrase "the body is provided with a liquid outlet channel 14 arranged along the axis."

[0083] Due to the cost and difficulty of manufacturing, generally speaking, the size of the liquid outlet channel 14 is roughly uniformly set along the axial direction of the rotating cylinder 3. If the liquid outlet channel 14 is to be made into different sizes along the axial direction of the rotating cylinder 3, it is very difficult on the one hand and very costly on the other hand. Therefore, in order to achieve the purpose of more uniform wetting of the cleaning part, the two technical routes of the above-mentioned liquid outlet part are conducive to simplifying the structure of the liquid outlet channel 14, that is, the size of the liquid outlet channel 14 is roughly uniformly set along the axial direction of the rotating cylinder 3. This technical situation is applicable to the two technical routes of the above-mentioned liquid outlet part. In other words, the liquid outlet part disclosed in the present invention does not require special arrangements for the size of the liquid outlet channel 14.

[0084] In some embodiments, the heating portion includes a heat conducting member 4, in which a flow channel 14 is provided. In another embodiment, the heat conducting member 4 does not have a flow channel 14, for example Figures 1 to 7 As shown, reference may be made to Examples 1 to 6.

[0085] In some embodiments, as Figure 16 、 19 As shown in Figures 20 and 25, a flow channel 14 is provided in the heat conductor 4, which is beneficial to improving the utilization rate of energy and reducing the volume, but increases the thickness of the heat conductor 4. Therefore, the present disclosure proposes that: the surface of the heat conductor 4 facing the rotating cylinder 3 at the flow channel 14 is a convex portion extending along the flow channel 14 and protruding in the direction of the rotating cylinder 3 and / or a convex portion protruding in the opposite direction, that is, there are three cases. The first is a convex portion extending along the flow channel 14 and protruding in the direction of the rotating cylinder 3, which can be called a first convex portion 36. The second is a convex portion extending along the flow channel 14 and protruding in the opposite direction of the rotating cylinder 3, which can be called a second convex portion 37. The third is a convex portion extending along the flow channel 14 and protruding in the direction of the rotating cylinder 3 and a convex portion protruding in the opposite direction, that is, it has both the first convex portion 36 and the second convex portion 37. Regardless of which one, the thickness and weight are reduced to a certain extent, especially the third one, which reduces the most. However, the first one is convenient for setting the heating element 5 on the back, and the second one is conducive to making the surface of the side of the heat-conducting element 4 facing the rotating cylinder 3 smoother.

[0086] In some embodiments, as Figure 16 、 19 As shown in FIG. 20 , the first convex portion 36 is an arc-shaped convex portion. Figure 21 As shown, the second protrusion 37 can also be an arc-shaped protrusion. When the first protrusion 36 is an arc-shaped protrusion, since it is located on the side of the heat-conducting member 4 facing the rotating cylinder 3, it is configured as an arc-shaped protrusion, which is conducive to contact with the cleaning part of the rotating cylinder 3. On the one hand, it does not damage the cleaning part, and on the other hand, it has little obstruction to the cleaning part.

[0087] In some embodiments, as Figure 16 、 19 As shown in Figures 20 and 25, there is an arc-shaped depression 38 between adjacent protrusions, especially on the side of the heat-conducting member 4 facing the rotating cylinder 3. On the one hand, the arc-shaped depression 38 is easy to process, and on the other hand, it has little effect on the strength of the heat-conducting member 4 and is not prone to stress concentration. On the other hand, the arc-shaped depression 38 does not damage the cleaning part, and on the other hand, it has little obstruction to the cleaning part.

[0088] In some embodiments, as Figure 2 、 4 , 16, 19, and 20, it also includes a scraping assembly and a liquid outlet portion. The liquid outlet portion is provided with a liquid outlet hole 7, which is used to output cleaning liquid to the cleaning portion. The scraping assembly is used to clean the cleaning portion wetted by the cleaning liquid.

[0089] In some embodiments, as Figure 2 、 3 As shown in Figures 10, 17, and 18, the cleaning device further includes a suction port 13 through which the wastewater is sucked away. This allows for timely wastewater treatment, preventing it from re-contaminating the surface being cleaned. The suction port 13 is connected to a suction pipe 32, through which the wastewater is sucked away in sequence. The suction port 13, the suction pipe 32, the filter assembly of the cleaning device, and the negative pressure assembly of the cleaning device are sequentially connected.

[0090] In some embodiments, as Figure 2 As shown, the scraping assembly is positioned away from the suction port 13. This design helps prevent the scraping assembly's adverse effects on the flow cross-section of the suction port 13, allowing the suction port 13 to fully utilize its performance. This avoidance of the suction port 13 does not require absolute avoidance, but rather involves taking certain measures to reduce the scraping assembly's obstruction of the suction port 13. This avoidance is acceptable when the adverse effects on the suction port 13 are minimal, but complete avoidance is even better.

[0091] In some embodiments, as Figure 2As shown, along the rotation direction of the rotating cylinder 3, the suction port 13 is in front and the scraping assembly is in the back. With this design, the cleaning part has already been processed by the suction port 13 before passing through the scraping assembly, which helps to reduce the burden of the scraping assembly. Conversely, since the cleaning part has already been processed by the suction port 13, the scraping assembly can better achieve the cleaning effect on the cleaning part after the subsequent processing.

[0092] In some embodiments, as Figure 2 、 39 As shown in FIG40 , the suction port 13 is located at the rear side of the rotating cylinder 3, and the scraping assembly is located on the upper side of the suction port 13. After being processed by the scraping assembly, the sewage naturally flows downward, and the suction port 13 can just suck away the sewage in time, thereby improving the cleaning efficiency.

[0093] In some embodiments, as Figure 2 、 39 As shown in FIG40, the scraping assembly adopts a scraping plate 12, which also serves as the second blocking portion 54. This design is relatively simple and reliable. The scraping plate 12 is used to remove sewage in the form of scraping, and in the direction of the axis of the rotating cylinder 3, the cleaning part can be fully cleaned and the sewage can be discharged, with a good effect.

[0094] In some embodiments, as Figure 3 、 10 , 17, further comprising a water pump 26. The rotating cylinder 3, the heating portion, and the water pump 26 are arranged in sequence from front to back, and the water pump 26 is used to pump the cleaning liquid.

[0095] In some embodiments, as Figure 3 、 10 As shown in FIG. 17 , the motor 29 is further included. The rotating cylinder 3, the heating unit, and the motor 29 are arranged in order from front to back. A transmission assembly 30 is provided between the motor 29 and the rotating cylinder 3. The motor 29 is used to drive the rotating cylinder 3 to rotate via the transmission assembly 30. The transmission assembly 30 is located outside the other end of the heating unit. This facilitates a more compact structure.

[0096] In some embodiments, as Figure 3 、 10 As shown in FIG. 17 , the water pump 26 and the motor 29 are arranged in a distributed manner on the left and right sides, and the water pump 26 is arranged toward the side where one end of the heating part is located. This is conducive to a more compact structure.

[0097] In some embodiments, as Figure 3 、 10 17, further comprising a roller brush frame 1, the roller brush frame 1 is provided with a mounting portion 31 on the rear side of the heating portion, the water pump 26 and the motor 29 are both mounted in the mounting portion 31. This facilitates better installation of the water pump 26 and the motor 29.

[0098] In some embodiments, as Figure 10 、 17 As shown, one end of the heating part is connected to a liquid inlet assembly, which is connected to a water pump 26. This facilitates a more compact structure. The liquid inlet assembly is, for example, a liquid inlet connector 16.

[0099] In some embodiments, as Figure 10 、 17 As shown, the liquid inlet assembly has a connector arranged at the rear side, which is connected to the output end of the water pump 26. This is conducive to a more compact structure. For example, the connector is connected to the output end of the water pump 26 through a connecting pipe.

[0100] In some embodiments, as Figure 2 、 4 As shown in Figures 8, 9, 39, and 40, the roller brush includes a heating portion and a liquid outlet portion that can be separated from each other. The heating portion includes a heat conductor 4 and a heating element 5. The heat conductor 4 and the liquid outlet are circumferentially arranged around the outer periphery of the rotating cylinder 3. The heating element 5 is thermally connected to the heat conductor 4, and the heat conductor 4 fits closely with the outer periphery of the rotating cylinder 3. Along the rotation direction of the rotating cylinder 3, the liquid outlet is located in front of and / or behind the heat conductor 4. 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 part 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.

[0101] In some embodiments, the present disclosure provides another roller brush, which is different from the above roller brush in that it uses another heating part and does not have a transition water tank 6. With this design, once a blockage occurs, only the liquid outlet 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 conductor 4, or can be separately provided. When the liquid outlet is detachably connected to the heat conductor 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 conductor 4 by the detachable connection, so that the heat conductor 4 remains on the roller brush and is not removed, for example Figure 8 、 9As shown in FIG11 , a bayonet 27 is provided at the front edge of the liquid outlet, and the bayonet 27 is detachably connected to the heating part. 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 element 5 and / or the heat conducting element 4, and then supplies the cleaning liquid to the liquid outlet after being heated by the heating element 5 and / or the heat conducting element 4, 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 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, the liquid outlet hole 7 can be cleaned without cleaning the heating unit. If a blockage requires replacement, only the liquid outlet needs to be replaced, while the heating unit remains on the roller brush frame 1 and does not require any operation or replacement. In other words, the heating unit can be reused.

[0102] Of course, the liquid outlet 7 can also be integrated, for example Figure 19 As shown, the present disclosure provides another heating portion, wherein the liquid outlet 7 is integrated on the main body 17 of the heating portion.

[0103] In some embodiments, the liquid outlet portion is provided with a liquid outlet channel 14 , and each liquid outlet hole 7 is connected to the liquid outlet channel 14 .

[0104] 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.

[0105] 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. The forward direction of the front-to-back direction refers to the direction close to the outer periphery of the rotating cylinder 3, and the backward direction of the front-to-back direction refers to the direction away from the outer periphery of the rotating cylinder 3. 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.

[0106] 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.

[0107] 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 at the liquid inlet joint 16 and 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] The following examples further illustrate the relevant technical solutions of the present disclosure:

[0115] Example 1:

[0116] The present disclosure provides 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, resulting in high efficiency, reduced heat waste, and improved heat utilization.

[0117] 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.

[0118] 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.

[0119] In some embodiments, as 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.

[0120] In some embodiments, as Figure 4 、 5As shown, the heating element includes a continuous heat-conducting member 4 and a discontinuous heating member 5 arranged along the axial direction. The heat-conducting member 4 is on the outside, and the heating member 5 is 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, which helps protect the heating member 5 and prolongs its service life.

[0121] The heating parts are continuously arranged along the axial direction of the rotating cylinder 3. This design can make the cleaning part evenly heated, which is beneficial to the drying performance.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] Example 2:

[0127] The difference between the second embodiment and the first embodiment is that a transition water tank 6 is added, and the heating part is used to heat the cleaning liquid supplied to the cleaning part.

[0128] When the transition water tank 6 is added, the structure is as follows: the heating part includes 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 to be connected to the water source, the heating element 5 is used to heat the cleaning liquid in the transition water tank 6, and the heated cleaning liquid flows to the cleaning part. In this way, the cleaning part is also heated by the heat brought by the cleaning liquid.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] In this example, if Figure 7 As 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.

[0133] With the above design, the cleaning liquid in the transition water tank 6 is used in the cleaning part after being heated, without the need for long-distance transportation, which greatly reduces waste. In addition, it also avoids the potential safety hazards caused by long-distance transportation.

[0134] like Figure 2 、3 , 4, 5, 6, 7, Figure 7 The middle arrow indicates the flow direction of the cleaning liquid. The 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.

[0135] 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.

[0136] In some embodiments, as 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.

[0137] In some embodiments, as 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.

[0138] 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.

[0139] When the surface to be cleaned is cleaned or the cleaning part itself is cleaned, the heating element 5 is kept on, so that the heat of the heating element 5 is used to dry the cleaning part.

[0140] Example 3:

[0141] The third embodiment also includes a scraper 12, which scrapes the cleaning part. This scraping is to scrape off the sewage and dirt on the cleaning part together, and then suck it away by the suction port 13 near the scraper 12. In the third embodiment, 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 is scraped first, and then the cleaning part is heated. This can make more efficient use of heat. This is because, if the sewage is not removed in time by the scraper 12, the part of the cleaning part where the sewage is located (the part of the cleaning part that is contaminated) will reabsorb heat, thus causing waste. The contaminated part of the cleaning part is not conducive to hygiene, so through the above design, heat is used more effectively, thereby improving hygiene. In addition, when executing the drying process of the cleaning part, it is helpful to increase the drying speed, further reducing waste.

[0142] Example 4:

[0143] The fourth embodiment is different from the above embodiments in that there can be multiple heating parts, each of which is arranged along the axial direction of the rotating cylinder 3, and 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 FIG. 4 . In the fourth embodiment, at least one heating part is sequentially added along the circumference of the rotating cylinder 3 to form a structure with two heating parts. Such a structure of the fourth embodiment is conducive to reaching the required temperature more quickly, and, if necessary, a higher temperature can be reached. However, the structure is relatively large and the energy consumption is high. In some occasions where a higher temperature is required, the fourth embodiment is more suitable.

[0144] Embodiment 5:

[0145] Compared with the above embodiments, the fifth embodiment is different in 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.

[0146] 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.

[0147] Example 6:

[0148] 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.

[0149] 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.

[0150] Embodiment seven:

[0151] Compared with Example 6, for example Figure 11 As shown, a recess 22 extending along the axis of the rotating cylinder 3 is provided on one side of the liquid outlet portion 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.

[0152] 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.

[0153] Embodiment 8:

[0154] Compared with the seventh embodiment, the eighth embodiment, for example Figure 19 、 20As shown, the difference is that it also includes a scraper 12, which serves as the scraping component, and the liquid outlet 7 and the scraper 12 are both integrated with the heat conductor 4, in this case, integrated with the main body 17. Specifically, the liquid outlet 7 is located near the upper edge of the main body 17, and the scraper 12 is located near the lower edge of the main body 17. The scraper 12 scrapes the cleaning part, that is, scrapes off the dirty water and dirt on the cleaning part, and then sucks them away by the suction port 13 near the scraper 12. Due to the integrated arrangement, the scraper 12 can also transfer some heat, that is, the hot scraper 12 has a better cleaning effect when processing the cleaning part than the cold scraper 12.

[0155] In some embodiments, as Figure 19 、 20 As shown, the scraper plate 12 and the heat conductor 4 are integrally provided, so that heat can be more easily transferred to the scraper plate 12 , thereby reducing heat waste. In addition, it is beneficial to simplify the structure and facilitate production.

[0156] When the surface to be cleaned is cleaned or the cleaning part itself is cleaned, the heating element 5 is kept on, so that the heat of the heating element 5 is used to dry the cleaning part.

[0157] Embodiment 9:

[0158] When the surface to be cleaned is cleaned or the cleaning part itself is cleaned, it is desired that the liquid outlet 7 no longer discharges liquid. In order to simply control the liquid discharge state of the liquid outlet 7, a flow channel on-off component that switches between a closed state and an open state is further included. The flow channel on-off component is provided on the flow channel that supplies the cleaning liquid. When in the closed state, the portion of the flow channel located before the flow channel on-off component is not connected to the liquid outlet 7. When in the open state, the portion of the flow channel located before the flow channel on-off component is connected to the liquid outlet 7. The liquid discharge from the liquid outlet 7 is controlled by the flow channel on-off component.

[0159] In some embodiments, as Figure 8 、 9 As shown in Figures 19, 20, 21 and 22, the present disclosure proposes a heating portion, in which a flow channel opening and closing component is provided at the inlet of the liquid outlet flow channel 14 or before the inlet.

[0160] In some embodiments, as Figure 21 、 22 As shown, the present disclosure proposes a heating part, the heat conducting member 4 is provided with four first flow channels, wherein, along the flow direction of the cleaning liquid, the last first flow channel of the four first flow channels serves as the liquid outlet channel 14, and the outlet end of the second to last first flow channel is provided with a flow channel on-off component.

[0161] In some embodiments, as Figure 21 、22 As shown, the outlet end of the first flow channel, located on one side of the transition groove 20, is equipped with a flow channel on-off assembly. This flow channel on-off assembly includes a sealing ring 35, a valve core, and a first elastic member 34. The sealing ring 35 is cooperatively arranged at the outlet end. The valve core is elastically pressed against the sealing ring 35 by one end of the first elastic member 34. The other end of the first elastic member 34 is supported by the protrusion 21. When the pressure of the cleaning liquid at the outlet end exceeds the elastic force of the first elastic member 34, the valve core opens, placing the flow channel on-off assembly in the open state. The above structure provides relatively simple and reliable control of the liquid outlet 7. For example, the water pump 26 generates pressure, and the valve core is controlled by the pressure change of the cleaning liquid to determine whether to open.

[0162] In some embodiments, as Figure 21 、 22 As shown, the valve core is, for example, a ball 33 .

[0163] In some embodiments, the flow channel on-off component is a solenoid valve structure, which switches the two states through electromagnetic force.

[0164] In some embodiments, the flow channel on-off component is a duckbill valve. When the pressure of the cleaning liquid at the outlet end is higher than the pressure required to open the duckbill valve, the duckbill valve opens to put the flow channel on-off component in an open state. The above structure is relatively simple and reliable for controlling the liquid outlet 7. For example, the water pump 26 generates pressure, and the duckbill valve is controlled by the pressure change of the cleaning liquid.

[0165] The flow channel on-off assembly may also have other structures, any of which are applicable to the present invention.

[0166] Embodiment 10:

[0167] For the drying solution, the solution to speed up the drying is to blow air to the cleaning part, that is, to set up an air blowing structure, which blows air to the cleaning part. After such a design, the gas generated by the heating part is quickly blown away, which is conducive to speeding up the drying.

[0168] In some embodiments, the negative pressure assembly of the cleaning device serves as the blowing mechanism. The negative pressure assembly is generally used for suction. When it is operated in reverse, it forms a blowing airflow, which can then blow air through the suction port of the cleaning device to the cleaning portion. With this design, the negative pressure assembly also serves as the blowing mechanism, simplifying the structure.

[0169] Example 11:

[0170] When the cleaning part is made of a fluffy material or a material that is prone to diameter changes, taking the fluffy material as an example, on the one hand, the cleaning part has better hair fluffiness when it is new, so the diameter is large, and the diameter will shrink after a period of use. On the other hand, the diameter of the cleaning part also changes after absorbing water and being squeezed by the scraper 12. Therefore, it becomes important to adapt to the changes in the outer diameter of the rotating cylinder 3 so that the heating part can better fit the outer periphery of the rotating cylinder 3.

[0171] The present disclosure proposes a roller brush, further comprising a floating support structure connected to the heating unit, which allows the heating unit to float and fit on the outer circumference, thereby facilitating the heating unit to adapt to changes in the outer diameter of the rotating cylinder 3.

[0172] In some embodiments, the floating support structure includes a second elastic member 39 and a floating support portion. The floating support portion is connected to the heating portion, and the floating support portion is used to support the heating portion to perform floating motion. The second elastic member 39 is used to provide an elastic force for the heating portion to float and fit on the outer periphery. The second elastic member 39 can be, for example, a compression spring, a tension spring, a torsion spring, etc. The specific form of the aforementioned floating support structure can be varied and cannot be exhaustively listed. The present disclosure exemplifies several examples, such as Figure 27 、 30 As shown, Figure 36 As shown, Figure 37 As shown, in Figure 27 、 30 A floating support structure with swinging and floating motion is disclosed in Figure 36 A floating support structure is disclosed that performs an up and down floating motion through a floating guide column 60. The floating guide column 60 cooperates with the upper and lower guide holes. Figure 36 The second elastic member 39 and the guide hole are not shown. Figure 37 A floating support structure is disclosed that performs floating movement in the front-rear direction through a floating guide groove 59. For example, both ends of the heat conductor 4 are connected to the floating guide groove 59, and the floating guide groove 59 supports the floating movement of the heat conductor 4 in the front-rear direction.

[0173] The floating support structure can also be other structures, for example Figure 38 As shown, the floating support structure includes an elastic support portion 56 connected to the heating unit. The elastic support portion 56 is used to provide an elastic force that allows the heating unit to float and adhere to the outer periphery. The elastic support portion 56 provides both support and the elastic force. The elastic support portion 56 can be made of an elastic material such as silicone, rubber, or elastic plastic that can provide support.

[0174] In some embodiments, as Figure 38As shown, the elastic body is further provided with an elastic hole 61 , into which the elastic material around the elastic body can be withdrawn, thereby achieving a greater displacement of the elastic body.

[0175] As can be seen from the above, there are many specific structural forms of floating support structures, and it is impossible to give all of them as examples. All applicable floating support structures can be applied to the present disclosure.

[0176] In some embodiments, as Figure 27 、 30 As shown, the floating support portion includes a swing member 40, one end of which is rotatable, and the other end of which is connected to the heating portion. The swing member 40 is used to support the heating portion to perform swinging and floating motion.

[0177] In some embodiments, as Figure 29 、 30 As shown, one end of the swinging member 40 is located at the rear side of the rotating cylinder 3, and the heating unit is located at the upper side of the rotating cylinder 3. The heating unit can swing around the end of the swinging member 40 toward the upper side of the rotating cylinder 3. With this design, the space above the roller brush is used as floating space for the heating unit, which helps to reduce the space occupied by the roller brush itself and thus facilitates the height control of the roller brush.

[0178] In some embodiments, as Figure 29 、 30 As shown, the floating support structure includes a cover 41, with a heating unit disposed on its underside. The cover 41 and the heating unit float together, forming an integral part of the upper cover 2 of the roller brush. With this design, the cover 41 floats together with the heating unit, forming an integral part of the upper cover 2 of the roller brush. Since roller brushes generally have an upper cover 2, which covers the internal structure of the cover 41 and provides a more attractive appearance, this improved solution eliminates the need for an additional outer shell to cover the floating support structure 41. This simplifies the structure while facilitating height control of the roller brush.

[0179] In some embodiments, as Figure 26 、 27 As shown in Figures 2 and 3, the upper cover 2 is provided with a side cover 42 for covering the drive mechanism of the roller brush. The cover 41 is provided with an extension 43 extending toward one side of the drive mechanism. The side cover 42 is provided with a recessed portion 44 at a position corresponding to the extension 43. The extension 43 and the recessed portion 44 are arranged vertically. This design not only solves the problem of covering the drive mechanism 41 of the roller brush, but also simplifies the structure. It also provides a continuous outer shell along the width of the roller brush, eliminating any joints along the width of the roller brush, which is beneficial for styling.

[0180] In some embodiments, as Figure 27 、 28As shown in Figures 29 and 30, the roller brush further includes a connecting portion located on the underside of the upper cover 2, with the floating support portion movably connected to the connecting portion. This design allows a portion of the floating support portion to be concealed within the underside of the upper cover 2, i.e., within the roller brush, while also providing a structural foundation for controlling the height and length of the roller brush.

[0181] In some embodiments, as Figure 27 、 30 As shown in Figures 31, 32, and 33, the connection portion includes a support 45 and a mounting seat 46. The floating support portion and the support 45 are movably connected to form a first assembly. The upper cover 2, the first assembly, and the mounting seat 46 are connected in sequence from top to bottom. With this design, since the floating support portion is a moving component, conventional installation is relatively complicated and needs to be solved. However, this design solution allows the floating support portion and the support 45 to be movably connected to form the first assembly. The first assembly is treated as a single part and installed with the upper cover 2 and the mounting seat 46. This makes installation very convenient and facilitates production assembly and mass production.

[0182] In some embodiments, as Figure 27 、 30 As shown in Figures 31, 32, and 33, the floating support is a swing member 40, one end of which is provided with a rotating shaft 58. After the upper cover 2 and the support 45 are connected, the rotating shaft 58 is rotatably limited. Before connection, the rotating shaft 58 can be inserted from top to bottom into the lower concave arc on the support 45. The upper cover 2 has an upper concave arc. After the upper cover 2 and the support 45 are connected, the lower concave arc and the upper concave arc form a rotational mating hole, and the rotating shaft 58 rotatably fits in the rotational mating hole. This design facilitates production and assembly and is conducive to mass production.

[0183] In some embodiments, as Figure 27 、 30 As shown, the upper cover 2 is provided with a first slot 47 opening downward, and the mounting base 46 is provided with a second slot 48 opening upward. The upper cover 2, first assembly, and mounting base 46 are sequentially connected from top to bottom, meaning that the upper cover 2, support 45, and mounting base 46 are plugged in sequentially from top to bottom. With this design, the first slot 47 facilitates the connection between the upper cover 2 and support 45, and the second slot 48 facilitates the connection between the support 45 and mounting base 46.

[0184] In some embodiments, as Figure 31 、 32 As shown in 33, 34 and 35, the upper cover 2 is connected to the first component to form a second component, and the second component is connected to the mounting base 46 up and down. After such design, it is beneficial to simplify production assembly, improve production efficiency and be beneficial to mass production.

[0185] In some embodiments, as Figure 35As shown, the upper cover 2 is provided with a connecting column 57. When the second component is connected to the mounting base 46 up and down, the upper cover 2 and the roller brush frame 1 are connected via the connecting column 57. The roller brush frame 1 is the base of the roller brush. When this connection is made, the connecting column 57 can be connected by screws driven from the side of the base facing the surface to be cleaned to lock the upper cover 2 and the roller brush frame 1. Therefore, the installation is convenient and conducive to mass production.

[0186] In some embodiments, as Figure 33 、 34 As shown in Figures 35 and 36, a second elastic member 39 is provided between the swinging member 40 and the upper cover 2. The second elastic member 39 is a compression spring. The upper cover 2, the compression spring, and the swinging member 40 are sequentially connected from top to bottom. The heating unit is elastically pressed against the rotating cylinder 3 by the compression spring. This design makes installation very convenient. In addition, when the upper cover 2 is connected to the first assembly to form the second assembly, the compression spring effectively prevents the upper cover 2 from becoming loose due to the elastic force of the indentation.

[0187] In some embodiments, a guide portion is provided between the upper cover 2 and the connecting portion, and the guide portion is connected to the swing member 40. This is conducive to the swinging motion of the swing member 40. The guide portion is, for example, Figure 32 、 33 As shown, a guide groove 49 is provided between the upper cover 2 and the connecting portion, and the swinging member 40 is guided and matched with the guide groove 49. The guide portion can also be other structures.

[0188] In some embodiments, as Figure 39 As shown, a third opening 50 is provided on the front side of the roller brush, opening toward one side of the rotating cylinder 3. This third opening 50 communicates with the interior of the roller brush. A floating support extends from this third opening 50 from the interior of the roller brush toward the side of the rotating cylinder 3. A heating unit is provided between the floating support and the rotating cylinder 3. The third opening 50 provides space for the floating support to move. This design facilitates a simple and compact structure.

[0189] In some embodiments, a seal is provided between the floating support portion and the third opening 50. This design is beneficial for preventing foreign matter, such as cleaning liquid, from entering the roller brush, thereby ensuring the performance of the roller brush.

[0190] In some embodiments, as Figure 30 、 39 As shown in FIG40 , the liquid outlet portion is further included, and the liquid outlet portion is provided separately from the heating portion. With this design, the heating portion can be made thinner and lighter, which is conducive to floating movement. On the other hand, the liquid outlet portion does not interfere with the floating movement of the heating portion. On the other hand, the liquid outlet portion imposes as few restrictions as possible on the shape or structural design of the heating portion. In other words, the shape or structure of the heating portion can be designed to better meet the needs of floating movement.

[0191] In some embodiments, as Figure 30 、 39 As shown in Figures 40 and 41 , the liquid outlet and the heating unit are sequentially arranged along the rotation direction of the rotating cylinder 3. With this design, the liquid outlet is located in front of the heating unit along the rotation direction of the rotating cylinder 3. When the cleaning unit absorbs the cleaning liquid delivered to it by the liquid outlet, its volume will change to a certain extent. However, due to the floating and contacting design of the heating unit and the cleaning unit, the heating unit has good heating performance for the cleaning unit. At the same time, because the liquid outlet is located in front of the heating unit, the heating unit can effectively heat the cleaning liquid for a longer time, thereby achieving high energy utilization and keeping the cleaning liquid at a higher temperature, which is beneficial for cleaning.

[0192] In some embodiments, as Figure 30 、 39 As shown in FIG. 40 , the liquid outlet is located at the front side of the roller brush. The portion of the front side of the roller brush located above the liquid outlet is provided with a third opening 50 that is open to one side of the rotating cylinder 3. The third opening 50 communicates with the interior of the roller brush. The floating support structure includes a floating support portion that extends from the third opening 50 from the interior of the roller brush to the side of the rotating cylinder 3. A heating portion is provided between the floating support portion and the rotating cylinder 3. The third opening 50 provides space for the floating support portion to move. A first seal 52 is provided between the floating support portion and the liquid outlet. The first seal 52 is used to prevent the cleaning liquid sprayed from the liquid outlet from entering the interior of the roller brush. The first seal 52 is conducive to preventing the cleaning liquid sprayed from the liquid outlet from entering the interior of the roller brush. Therefore, it is conducive to the third opening 50 and the liquid outlet being arranged adjacent to each other in the upper and lower parts, thereby saving height space. Through the third opening 50, the interior of the roller brush can be used to accommodate a portion of the floating support portion. This improvement is conducive to controlling the height and length of the roller brush, and the structure is also relatively compact.

[0193] The more ideal state is to provide a seal between the floating support part and the third opening 50, but the structure will be relatively complicated, the cost will increase, and it will be inconvenient to produce. In the present disclosure, the heating part floats upward, mainly because the lower side of the floating support part and the upper side of the third opening 50 are closer to the liquid outlet part, so it is easier for the clean liquid to enter. In this way, the provision of the first seal 52 can better solve the sealing problem while avoiding the problem of structural complexity.

[0194] In some embodiments, a first blocking portion 53 extending toward one side of the rotating cylinder 3 is provided on the upper side of the liquid outlet. Specifically, Figure 30 、 39As shown in FIG40 , a first blocking portion 53 is provided on the upper side of the front side portion 51 of the liquid outlet, and a liquid outlet hole 7 is provided on the front side portion 51. This design helps prevent cleaning liquid ejected from the liquid outlet from entering the interior of the roller brush and also facilitates achieving the aforementioned goal of using the first sealing member 52 to solve the sealing problem while simplifying the structure. In some embodiments, the liquid outlet hole 7 is located adjacent to the first blocking portion 53.

[0195] In some embodiments, as Figure 30 、 39 As shown in FIG40 , the first sealing member 52 is arranged to move with the floating support portion. During the movement, the first sealing member 52 and the first blocking portion 53 always maintain a sealed connection. This design helps to prevent the cleaning liquid ejected from the liquid outlet from entering the roller brush for a long time, thereby ensuring the performance of the roller brush.

[0196] In some embodiments, as Figure 30 、 39 As shown in Figure 40, it also includes a connecting portion located on the lower side of the upper cover 2 of the roller brush, the connecting portion including a support 45 and a mounting seat 46. The floating support portion and the support 45 are movably connected to form a first assembly. The first sealing member 52 is connected to the first assembly. The upper cover 2 and the first assembly are connected to form a second assembly. The second assembly is connected to the mounting seat 46 in an up-down manner. The first sealing member 52 of the first assembly and the first blocking member 53 are sealed together by the up-down connection between the second assembly and the mounting seat 46. With this design, the structure is further optimized and production and assembly are facilitated, taking into account the needs of floating movement and sealing. That is, the up-down connection between the second assembly and the mounting seat 46 simultaneously completes the installation of the second assembly and the sealing cooperation between the first sealing member 52 and the first blocking member 53.

[0197] In some embodiments, as Figure 30 As shown, the first seal 52 is a hollow elastic sealing strip (it can also be a sealing strip of other structural forms). Since the first seal 52 is movable relative to the first blocking portion 53, the aforementioned sealing strip structure is adopted, which is conducive to maintaining the sealing fit in the moving state. In addition, the elastic sealing strip has an elastic supporting effect on the first component, that is, the first seal 52 has a certain elastic supporting effect on the heating part. Then, combined with the second elastic member 39, the heating part is essentially sandwiched between the two elastic supports, so that the floating movement of the heating part is not prone to hard collision. In addition, the combination of the first seal 52 and the second elastic member 39 provides a structural basis for optimizing the pressure of the heating part against the periphery of the cleaning part, that is, an adjustment technical means. The optimization of the pressure is conducive to achieving the change of the outer diameter of the adaptive rotating cylinder 3 while also being beneficial to the operation and life of the rotating cylinder 3, that is, avoiding the high pressure hindering the rotation movement of the rotating cylinder 3 and / or causing large wear on the periphery of the rotating cylinder 3.

[0198] In some embodiments, a second blocking portion 54 is provided on the lower side of the liquid outlet portion, and the second blocking portion 54 is connected to the cleaning portion. The second blocking portion 54 is used to prevent the cleaning liquid sprayed from the liquid outlet portion from leaking downward. Specifically, Figure 30 、 39 As shown in FIG40 , a second blocking portion 54 is provided on the lower side of the front side portion 51 of the liquid outlet. This design is beneficial to the effective use of the cleaning liquid on the one hand and avoids wetting the cleaned surface on the other hand.

[0199] In some embodiments, as Figure 30 、 39 As shown in FIG40 , the second blocking portion 54 also serves as a scraper 12 , which scrapes the cleaning portion before the cleaning portion enters the liquid outlet portion.

[0200] In some embodiments, as Figure 30 、 32 As shown in FIG40 , the third opening 50 is provided with a partition 55, through which the floating support portion passes and movably cooperates. With this design, the partition 55 has the ability to block the entry of foreign matter, thereby facilitating the above-mentioned purpose of using the first sealing member 52 to solve the sealing problem while simplifying the structure.

[0201] In some embodiments, as Figure 30 、 32 As shown in FIG. 40 , the partition 55 is provided by the front side plate of the support 45 . In addition, the second assembly is connected to the mounting base 46 up and down to simultaneously complete the partitioning of the third opening 50 . This design greatly simplifies the structure and production assembly.

[0202] For 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 disclosure can be applied to the present disclosure.

[0203] When understanding the present invention, if necessary, the above structure can refer to other embodiments / appendices. Figure 1 And understand, no further elaboration here.

[0204] 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.
