Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning equipment, and particularly relates to a crawler mechanism, a floor brush, a cleaning equipment and a cleaning system. Background Art

[0002] During the use of some cleaning equipment such as floor sweepers, floor scrubbers, vacuum cleaners, etc., the cleaning crawler in the cleaning mechanism needs to be removed from the driving roller and the driven roller due to reasons such as replacement and crawler cleaning, and the cleaning crawler needs to be installed before the cleaning equipment is used again. However, since the cleaning crawler is tensioned by the driving roller and the driven roller, when disassembling and assembling, it is necessary to pull the cleaning crawler and contact the driving roller, the driven roller or the cleaning crawler to realize the disassembly and assembly of the cleaning crawler. The disassembly and assembly process of the cleaning crawler is time-consuming and laborious, and it is also easy to get hands dirty, bringing a bad use experience to users. Summary of the Utility Model

[0003] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a crawler mechanism, a floor brush, a cleaning equipment and a cleaning system, which are used to solve the problem of difficult disassembly and assembly of the cleaning crawler in the prior art.

[0004] To achieve the above purpose and other related purposes, the present utility model provides a crawler mechanism, which is arranged on a floor brush, and an installation bracket is arranged on the floor brush. The crawler mechanism includes:

[0005] A crawler cleaning unit, including a driving component and a cleaning component. The cleaning component is detachably connected to the installation bracket. The cleaning component includes a driving roller, a driven roller and a cleaning crawler. The cleaning crawler is sleeved outside the driving roller and the driven roller;

[0006] A connecting bracket, including a first snap ring and a second snap ring. The first snap ring is installed on the driving roller, and the driving roller can rotate relative to the first snap ring along its own axis. The second snap ring is installed on the driven roller, and the driven roller can rotate relative to the second snap ring along its own axis. An elastic tensioning structure is arranged between the first snap ring and the second snap ring. The elastic tensioning structure makes the driving roller and the driven roller keep a movement trend of approaching each other.

[0007] Correspondingly: An installation bracket is arranged on the floor brush to realize the installation of the crawler mechanism. The cleaning component is detachably connected to the installation bracket to facilitate the disassembly and assembly of the cleaning component. The cleaning crawler is sleeved outside the driving roller and the driven roller. Through the arrangement of the driving component, the driving roller in the cleaning component is driven to act, and the driven roller can act with the driving roller under the drive of the cleaning crawler. The first snap ring is sleeved outside the driving roller, and the second snap ring is sleeved outside the driven roller to facilitate the installation of the elastic tensioning structure. The arrangement of the elastic tensioning structure makes the driving roller and the driven roller keep a movement trend of approaching each other.

[0008] Since the cleaning track of the floor washer has a larger contact area with the surface to be cleaned compared to the roller brush, after the floor washer is used, the dirt on the cleaning track is not easily completely removed during self-cleaning. Therefore, it is necessary to disassemble the cleaning track for cleaning. Moreover, the bristles on the surface of the cleaning track will wear out after long-term cleaning. A worn cleaning track cannot guarantee the cleaning performance and needs to be replaced. Therefore, the disassembly and assembly of the cleaning track are required.

[0009] In the prior art, when it is necessary to disassemble the cleaning track, since the cleaning track is internally supported and tensioned by the driving roller and the driven roller, it is necessary to manually and forcibly pull the cleaning track along the axial directions of the driving roller and the driven roller. Since both the driving roller and the driven roller internally support and tension the cleaning track, the static friction is relatively large. Therefore, it is extremely difficult to remove the cleaning track, and the hands will be soiled by the driving roller, the driven roller, and the cleaning track during the operation. At the same time, the installation operation of the cleaning track is also inconvenient.

[0010] Alternatively, manually adjust the distance between the driving roller and the driven roller to make the driving roller and the driven roller move closer to each other, so that the driving roller and the driven roller lose the internal support and tension on the cleaning track, and then manually pull out the cleaning track along the axial directions of the driving roller and the driven roller. However, the cleaning track is originally sleeved outside the driving roller and the driven roller. When the hand exerts force to hold the cleaning component tightly to adjust the distance between the driving roller and the driven roller, the track will closely adhere to the outer walls of the driving roller and the driven roller, making it very difficult to remove the cleaning track. And the hands will be soiled by the driving roller, the driven roller, and the cleaning track during the operation. At the same time, the installation operation of the cleaning track is also inconvenient.

[0011] In this solution, after the cleaning component is removed from the mounting bracket, the driving roller and the driven roller are separated from the mounting bracket, so that the driving roller and the driven roller lose the positioning and support provided by the mounting bracket. Therefore, under the elastic tension of the elastic tension structure on the first snap ring and the second snap ring, the driving roller and the driven roller can move towards each other radially, so as to realize the automatic mutual approach of the driving roller and the driven roller.

[0012] Since the driving roller and the driven roller approach each other, the distance between the driving roller and the driven roller decreases. At this time, the driving roller and the driven roller no longer maintain the internal support and tension on the cleaning track, and the cleaning track switches from the tensioned state to the relaxed state. Since the cleaning track is relaxed relative to the driving roller and the driven roller, the edge of the cleaning track can be pinched and the cleaning track can be easily pulled out relative to the driving roller and the driven roller along the axial direction of the driving roller and the driven roller, without the need to manually reduce the distance between the driving roller and the driven roller, thus facilitating the removal of the cleaning track and increasing the convenience of removing the cleaning track. At the same time, the installation operation of the cleaning track can be facilitated.

[0013] Since there is no need to manually reduce the distance between the driving roller and the driven roller, the cleaning track can be removed conveniently, the time consumed for removal is reduced, and the probability of contacting the cleaning track, the driving roller or the driven roller during the removal process will be reduced. Since the hands will not touch the driving roller and the driven roller, only the edge of the cleaning track needs to be pinched by the fingers to achieve disassembly, so the possibility of dirty hands is greatly reduced.

[0014] When installing the cleaning track, since the driving roller and the driven roller have been tightened by the elastic tension structure, it is convenient to put the cleaning track over the driving roller and the driven roller. Along with the positioning and installation of the cleaning component on the mounting bracket, the cleaning track put over the driving roller and the driven roller will be tensioned, and the connecting bracket forms a tensile force on the driving roller and the driven roller, which can limit their shaking during the operation of the driving roller and the driven roller and is beneficial to their stable operation. Optionally, there are an installation state and a removal state between the cleaning component and the mounting bracket. In the installation state, the driving roller and the driven roller are installed on the mounting bracket and can rotate respectively along their own axes; in the removal state, the driving roller and the driven roller are separated from the mounting bracket.

[0015] Correspondingly: Since the cleaning component is detachable from the mounting bracket, there are an installation state and a removal state between the cleaning component and the mounting bracket. In the installation state, the driving roller and the driven roller are respectively installed on the mounting bracket, and the cleaning track is tensioned by the driving roller and the driven roller. In the removal state, the driving roller and the driven roller are separated from the mounting bracket, and under the elastic action of the elastic tension structure, the driving roller and the driven roller move closer to each other, so that the cleaning track can be detached from the driving roller and the driven roller.

[0016] In this solution, the cleaning component can be disassembled and assembled. Compared with the case where it cannot be disassembled and assembled, this solution can realize operations such as replacement of the cleaning component, removal for maintenance, and removal for cleaning.

[0017] Optionally, there is a close state position and a far state position between the driving roller and the driven roller. In the removal state, the driving roller and the driven roller move closer to each other under the elastic action of the elastic tension structure and reach the close state position; in the installation state, the driving roller and the driven roller are far away from each other and reach the far state position.

[0018] Correspondingly: In the removal state, the driving roller and the driven roller are removed from the mounting bracket together. Due to the setting of the elastic tension structure, the driving roller and the driven roller move closer to each other and reach the close state position, making the originally tensioned cleaning track loose, which is convenient for the disassembly and assembly of the cleaning track. In the installation state, the driving roller and the driven roller are installed on the mounting bracket and are limited to the far state position by the mounting bracket. The driving roller and the driven roller are far away from each other, and the cleaning track is tensioned by the driving roller and the driven roller to facilitate cleaning.

[0019] In this solution, after the cleaning track belt comes together between the driving roller and the driven roller, it will automatically slacken and can be easily removed from the driving roller and the driven roller. Compared with manually pulling the cleaning track belt in the prior art, the possibility of the cleaning track belt being pulled and damaged is avoided, and at the same time, the possibility of dirty hands is reduced.

[0020] Optionally, the elastic tensioning structure includes:

[0021] A stop portion provided on one of the first snap ring and the second snap ring;

[0022] A connecting arm provided on the other of the first snap ring and the second snap ring, the connecting arm being movably connected to the stop portion to move the driving roller and the driven roller closer or farther apart;

[0023] An elastic member sleeved on the connecting arm, the elastic member causing the driving roller and the driven roller to maintain a tendency to move closer to each other.

[0024] Correspondingly: The setting of the stop portion is for facilitating the installation of the elastic member. The setting of the elastic member is for driving the change of the positional relationship between the driving roller and the driven roller, so that the driving roller and the driven roller can switch from the separated state position to the close state position.

[0025] Optionally, the connecting bracket further includes a buckle, at least part of the buckle is embedded in the connecting groove on the first snap ring, and the stop portion is provided on the buckle.

[0026] Correspondingly: The connecting groove is provided on the first snap ring for facilitating the installation of the buckle and realizing the detachable connection between the buckle and the first snap ring. The stop portion is provided on the buckle, and the detachable connection between the buckle and the first snap ring is for facilitating the assembly of the elastic tensioning structure.

[0027] Optionally, an activity groove is provided in the buckle, the connecting arm extends into the activity groove and is movably connected to the activity groove, a limiting member is provided at the end of the connecting arm, and a limiting portion is provided on the limiting member; the elastic member includes a compression spring, and both ends of the compression spring are respectively abutted against the end face of the activity groove and the limiting portion.

[0028] Correspondingly: The setting of the activity groove is for facilitating the connecting arm to move in the activity groove. The setting of the limiting member and the limiting portion on the limiting member is for facilitating the installation and limitation of the elastic member and at the same time facilitating the assembly of the elastic tensioning structure. When assembling the elastic tensioning structure, the connecting arm can be extended into the buckle, then the limiting member can be installed, and then the buckle can be installed in the connecting groove. Compared with setting the limiting member to be integral with the connecting arm, the assembly convenience can be effectively increased.

[0029] Optionally, the elastic tensioning structure includes a tension spring, and the tension spring connects the first snap ring and the second snap ring.

[0030] Correspondingly, a first snap ring is sleeved outside the driving roller, a second snap ring is sleeved outside the driven roller, and a tension spring is arranged between the first snap ring and the second snap ring, so that the driving roller and the driven roller maintain a movement trend of approaching each other. Compared with the arrangement of the connecting arm, the stop portion and the limiting portion, the structure is simpler and the required cost is lower.

[0031] Optionally, a first mounting groove is circumferentially arranged on the driving roller, a second mounting groove is circumferentially arranged on the driven roller, the first snap ring is mounted in the first mounting groove through a first bearing, and the second snap ring is mounted in the second mounting groove through a second bearing.

[0032] Correspondingly, the arrangement of the first mounting groove and the second mounting groove facilitates the installation of the first snap ring and the second mounting. The arrangement of the first bearing and the second bearing facilitates the rotation of the driving roller and the driven roller relative to the connecting bracket.

[0033] To achieve the above object and other related objects, the present invention provides a track mechanism arranged on a floor brush, and an installation bracket is arranged on the floor brush. The track mechanism includes:

[0034] A track cleaning unit, including a driving component and a cleaning component, the cleaning component is detachably connected to the installation bracket, the cleaning component includes a driving roller, a driven roller and a cleaning track, and the cleaning track is sleeved outside the driving roller and the driven roller;

[0035] A pulling belt, located inside the cleaning track and sleeved outside the driving roller and the driven roller, provides a pulling force for the driving roller and the driven roller to approach each other, and transmits power from the driving roller to the driven roller.

[0036] Correspondingly, an installation bracket is arranged on the floor brush to achieve the installation of the track mechanism. The cleaning component is detachably connected to the installation bracket to facilitate the disassembly and assembly of the cleaning component. The cleaning track is sleeved outside the driving roller and the driven roller. Through the arrangement of the driving component, the driving roller in the cleaning component is driven to move, and the driven roller can move with the driving roller under the drive of the cleaning track. The arrangement of the pulling belt enables the driving roller and the driven roller to maintain a movement trend of approaching each other.

[0037] In this solution, after the cleaning component is removed from the installation bracket, the driving roller and the driven roller can approach each other under the elastic action of the pulling belt, and the cleaning track switches from the tensioned state to the relaxed state, which facilitates the removal of the cleaning track and increases the convenience of removing the cleaning track. Since the cleaning track is easy to remove, the removal time is reduced, and the probability of contacting the cleaning track, the driving roller or the driven roller during the removal process will be reduced, thereby reducing the possibility of dirty hands.

[0038] When installing the cleaning track, since the driving roller and the driven roller have been tightened by the tension belt, it is convenient to put the cleaning track over the driving roller and the driven roller. Along with the positioning and installation of the cleaning assembly on the mounting bracket, the cleaning track sleeved over the driving roller and the driven roller will be tensioned. The tension belt forms a pulling force on the driving roller and the driven roller, which can limit their wobbling during the rotation of the driving roller and the driven roller, facilitating stable operation. Optionally, a first mounting groove is circumferentially provided on the driving roller, a second mounting groove is circumferentially provided on the driven roller, and the tension belt is arranged in the first mounting groove and the second mounting groove.

[0039] Correspondingly, the first mounting groove and the second mounting groove are provided to enable the installation of the tension belt and reduce the possibility of the tension belt moving along the axis of the driving roller or the driven roller.

[0040] Optionally, a first guiding portion is longitudinally provided on the inner surface of the tension belt, and a second guiding portion cooperating with the first guiding portion is circumferentially provided in the first mounting groove and the second mounting groove.

[0041] Correspondingly, the first guiding portion and the second guiding portion are provided to reduce the possibility of the tension belt running off track.

[0042] Optionally, the thickness of the tension belt is greater than the depth of the first mounting groove and the depth of the second mounting groove, and the outer surface of the tension belt protrudes above the roller surfaces of the driving roller and the driven roller and contacts the inner surface of the cleaning track.

[0043] Correspondingly, in the prior art, in order to prevent the cleaning track from shifting on the driving roller and the driven roller, a rubber layer for increasing friction is often provided on the driving roller and the driven roller. However, in this solution, there is no need to provide a rubber layer on the driving roller and the driven roller. By the contact between the outer surface of the tension belt and the inner surface of the cleaning track, the frictional force between the outer surface of the tension belt and the inner surface of the cleaning track can reduce the possibility of the cleaning track slipping and moving, facilitating the stable operation of the cleaning track.

[0044] Optionally, the tension belt is arranged in multiple strips along the axial directions of the driving roller and the driven roller.

[0045] Correspondingly, multiple tension belts are provided to increase the pulling force between the driving roller and the driven roller. At the same time, the force balance between the driving roller and the driven roller is increased.

[0046] Optionally, the roller surfaces of the driving roller and the driven roller are smooth surfaces.

[0047] Correspondingly, the surface of the cleaning track in contact with the driving roller and the driven roller is a rubber surface. When the roller surfaces of the driving roller and the driven roller are smooth surfaces, it can instead increase friction, ensure stable transmission, increase the locked-rotor current, and facilitate the identification of abnormal states.

[0048] Optionally, the cleaning component and the mounting bracket have an installed state and a removed state. In the installed state, the active roller and the driven roller are installed on the mounting bracket and can rotate along their own axes; in the removed state, the active roller and the driven roller are separated from the mounting bracket.

[0049] Correspondingly: Since the cleaning assembly is detachable from the mounting bracket, the cleaning assembly and the mounting bracket have an installed state and a removed state. In the installed state, the active roller and the driven roller are respectively installed on the mounting bracket, and the cleaning track is tensioned by the active roller and the driven roller. In the removed state, the active roller and the driven roller are separated from the mounting bracket, and the active roller and the driven roller are moved closer to each other under the elastic action of the pull belt, so that the cleaning track can be separated from the active roller and the driven roller.

[0050] Optionally, the active roller and the driven roller have a close state position and a distant state position. In the removed state, the active roller and the driven roller move closer to each other under the elastic action of the pull belt and reach the close state position; in the installed state, the active roller and the driven roller move away from each other and reach the distant state position.

[0051] Corresponding: In the dismantling state, the active roller and the driven roller are removed from the mounting bracket together. Due to the setting of the pull belt, the active roller and the driven roller are brought closer to each other and reach the close state position, so that the originally tensioned cleaning track is relaxed, which is convenient for the disassembly and assembly of the cleaning track. In the installation state, the active roller and the driven roller are installed on the mounting bracket, and the mounting bracket is limited in the away state position. The active roller and the driven roller are away from each other, and the cleaning track is tensioned by the active roller and the driven roller to facilitate cleaning.

[0052] In order to achieve the above-mentioned purpose and other related purposes, the utility model provides a floor brush, including a shell, a mounting bracket and the crawler mechanism, wherein the crawler mechanism is mounted on the mounting bracket.

[0053] Correspondingly: the setting of the shell can protect the crawler mechanism, etc. The setting of the mounting bracket facilitates the installation of the crawler mechanism. Compared with the use of a roller brush, the setting of the crawler mechanism can increase the cleaning area and reduce hair entanglement.

[0054] Optionally, the mounting bracket includes a first side plate and a second side plate, the first side plate is fixed to the shell, the second side plate is detachably connected to the shell, and the cleaning assembly is detachably mounted between the first side plate and the second side plate.

[0055] Corresponding: The second side plate is detachably connected to the housing so as to drive the cleaning assembly to separate from the first side plate through the second side. The cleaning assembly is detachably installed between the first side plate and the second side so as to detach the cleaning assembly from the first side and the second side.

[0056] Optionally, the driving component is installed on the first side plate, and a docking portion for docking the driving roller and the driven roller is further provided on the first side plate. The driving roller and the driven roller are detachably installed on the docking portion and can rotate respectively along their own axes.

[0057] Corresponding: The driving component may not be detached along with the cleaning assembly. Therefore, the driving component is installed on the first side. A docking portion is provided on the first side to facilitate the quick installation of the driving roller and the driven roller in place.

[0058] Optionally, a supporting portion for supporting the driving roller and the driven roller is provided on the second side plate. The driving roller and the driven roller are detachably installed on the supporting portion and can rotate respectively along their own axes.

[0059] Corresponding: The provision of the supporting portion realizes the support and installation positioning of the driving roller and the driven roller.

[0060] Optionally, a docking port is provided inside the driving roller, and the docking port is docked with the output end of the driving component so that the driving roller can rotate under the drive of the driving component.

[0061] Corresponding: The driving component is installed on the first side plate. When the cleaning assembly is detached, the driving component is separated from the driving roller. When the cleaning assembly is reinstalled, if the driving component is required to drive the driving roller to act, the output end of the driving component needs to be docked with the driving roller to drive the driving roller to act. Therefore, a docking port is provided inside the driving roller.

[0062] Optionally, a handle and a storage groove are provided on the second side plate, and the handle can rotate and be stored in the storage groove.

[0063] Corresponding: The provision of the handle facilitates the pulling out of the second side and the cleaning assembly, and facilitates the disassembly and assembly of the cleaning assembly. The provision of the storage groove facilitates the storage of the handle, avoiding the handle occupying external space and affecting the cleaning work of the floor brush.

[0064] Optionally, two sets of track mechanisms are provided, and the track mechanisms are distributed at both ends of the housing.

[0065] Corresponding: The provision of two sets of track mechanisms can further increase the cleaning area, increase the ground pressure, and improve the cleaning efficiency.

[0066] Optionally, two sets of the crawler mechanisms are installed on the same second side plate;

[0067] Or

[0068] On the housing, second side plates are respectively provided corresponding to the two sets of crawler mechanisms, and the crawler mechanisms are respectively installed on the corresponding second side plates.

[0069] Correspondingly: When two sets of crawler mechanisms are installed on the same second side plate, pulling the second side can pull out the two sets of crawler mechanisms for disassembly and assembly operations. If the two sets of crawler mechanisms are respectively installed on different second side plates, the corresponding second side plates need to be operated respectively to realize the disassembly and assembly operations of the corresponding crawler mechanisms.

[0070] Optionally, an adsorption channel is provided in the housing, an opening of the adsorption channel is arranged between the two sets of crawler mechanisms, a scraping rack is arranged along the opening of the adsorption channel, and the scraping rack is located on the surface of the cleaning crawler and has a matching shape.

[0071] Correspondingly: The adsorption channel is arranged between the two sets of crawler mechanisms. Compared with being arranged at the front and rear ends of the floor brush, the adsorption wind force is more concentrated, and it also plays a role in reducing the occupied volume of the adsorption channel. The setting of the scraping rack serves to clean the surface of the cleaning crawler. The shape of the scraping rack matches the surface shape of the cleaning crawler to increase the cleaning ability of the cleaning crawler.

[0072] To achieve the above and other related purposes, the present utility model provides a cleaning device, including a machine body and the floor brush as described above, and the machine body is installed on the floor brush.

[0073] Correspondingly: The setting of the machine body facilitates the operation of the floor brush.

[0074] Optionally, the machine body includes a push rod, and a fresh water tank, a sewage tank and a suction power mechanism arranged on the push rod. The inlet of the suction power mechanism is communicated with the sewage tank, and the sewage tank is communicated with the adsorption channel.

[0075] Correspondingly: The setting of the fresh water tank provides fresh water for the crawler cleaning unit to clean the ground. The setting of the sewage tank stores sewage and ground garbage. The setting of the suction power mechanism provides power for sucking sewage and garbage into the sewage tank.

[0076] To achieve the above and other related purposes, the present utility model provides a cleaning system, including the cleaning device as described above, and a base or a base station, and the base or the base station is used for placing the cleaning device.

[0077] Correspondingly: The setting of the base or the base station realizes the placement of the cleaning device.

[0078] As described above, the crawler mechanism, floor brush, cleaning device, and cleaning system of the present utility model have the following beneficial effects:

[0079] In this solution, the connecting bracket or the pulling belt is provided to make the driving roller and the driven roller have a tendency to approach each other. After the cleaning assembly is removed from the connecting bracket, the driving roller and the driven roller approach each other, and the cleaning crawler originally tensioned by the driving roller and the driven roller becomes loose, so that the cleaning crawler can directly disengage from the driving roller and the driven roller, or it is convenient for the cleaning crawler to disengage from the driving roller and the driven roller, facilitating the removal of the cleaning crawler. When assembling the cleaning crawler, the driving roller and the driven roller approach each other under the action of the connecting bracket or the pulling belt. At this time, it is easy to put the cleaning crawler over the driving roller and the driven roller, which plays a role in facilitating the installation of the cleaning crawler.

[0080] It should also be noted that in the prior art, when the cleaning crawler is removed, the driving roller and the driven roller are in a separated state, and the cleaning crawler is still in a tensioned state. Removing the cleaning crawler requires repeatedly pulling the cleaning crawler, the driving roller, and the driven roller, resulting in dirty hands. In the solution, during the disassembly and assembly of the cleaning crawler, the driving roller and the driven roller are in a state of approaching each other, and the cleaning crawler switches from a tensioned state to a loose state, so that the cleaning crawler can be more easily removed from or installed on the driving roller and the driven roller, effectively increasing the convenience of disassembly and assembly of the cleaning crawler. At the same time, due to the convenience of disassembly and assembly of the cleaning crawler, the number of times of contacting the cleaning crawler, the driving roller, and the driven roller is reduced, thereby reducing the possibility of dirty hands. The setting of the connecting bracket or the pulling belt in this solution also internally fixes the driving roller and the driven roller, increasing the running stability.

[0094] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification.

[0095] Refer to the attached Figure 1 and the attached Figure 2 As shown, the present application provides a track mechanism disposed on the floor brush 1. An installation bracket 13 is provided on the floor brush 1. The track mechanism includes:

[0096] Track cleaning unit 11, including a driving component 111 and a cleaning assembly 112. The cleaning assembly 112 is detachably connected to the installation bracket 13. The cleaning assembly 112 includes a driving roller 1121, a driven roller 1122, and a cleaning track 1123. The cleaning track 1123 is sleeved outside the driving roller 1121 and the driven roller 1122;

[0097] The connecting bracket 10 includes a first clamping ring 101 and a second clamping ring 102. The first clamping ring 101 is installed on the driving roller 1121, and the driving roller 1121 can rotate relative to the first clamping ring 101 along its own axis. The second clamping ring 102 is installed on the driven roller 1122, and the driven roller 1122 can rotate relative to the second clamping ring 102 along its own axis. An elastic tensioning structure is provided between the first clamping ring 101 and the second clamping ring 102, and the elastic tensioning structure makes the driving roller 1121 and the driven roller 1122 maintain a movement trend of approaching each other.

[0098] When removing the cleaning assembly 112, first remove the cleaning assembly 112 from the mounting bracket 13. The driving roller 1121 and the driven roller 1122 approach each other under the elastic action of the elastic tensioning structure, so that the cleaning track 1123 tensioned by the driving roller 1121 and the driven roller 1122 becomes slack. Then, the cleaning track 1123 can be removed from the driving roller 1121 and the driven roller 1122, effectively increasing the convenience of removing the cleaning track 1123.

[0099] When assembling the cleaning assembly 112, first put the cleaning track 1123 over the driving roller 1121 and the driven roller 1122 that approach each other, and then install the driving roller 1121 and the driven roller 1122 at the corresponding positions on the mounting bracket 13. Due to the limitation of the installation positions on the mounting bracket 13, the driving roller 1121 and the driven roller 1122 move away from each other against the elastic force of the elastic tensioning structure, and the cleaning track 1123 is tensioned. During the installation process of the cleaning track 1123, the driving roller 1121 and the driven roller 1122 approach each other under the elastic action of the elastic tensioning structure, which is convenient for putting the cleaning track 1123 over the driving roller 1121 and the driven roller 1122, increasing the convenience of installing the cleaning track 1123.

[0100] In an exemplary embodiment, there are an installation state and a removal state between the cleaning assembly 112 and the mounting bracket 13. In the installation state, the driving roller 1121 and the driven roller 1122 are installed on the mounting bracket 13 and can rotate respectively along their own axes; in the removal state, the driving roller 1121 and the driven roller 1122 are separated from the mounting bracket 13.

[0101] It should be noted that since the cleaning assembly 112 and the mounting bracket 13 are detachably connected, there are an installation state and a removal state between the cleaning assembly 112 and the mounting bracket 13. Due to the setting of the elastic tensioning structure, when the cleaning assembly 112 switches from the installation state to the removal state, the driving roller 1121 and the driven roller 1122 approach each other. Due to the limitation of the installation positions of the driving roller 1121 and the driven roller 1122 by the mounting bracket 13, when the cleaning assembly 112 switches from the removal state to the installation state, the driving roller 1121 and the driven roller 1122 move away from each other.

[0102] In an exemplary embodiment, there are a close state position and a far state position between the driving roller 1121 and the driven roller 1122. In the removal state, the driving roller 1121 and the driven roller 1122 approach each other under the elastic action of the elastic tension structure and reach the close state position; in the installation state, the driving roller 1121 and the driven roller 1122 are far from each other and reach the far state position.

[0103] It should be noted that, during the process of switching between the installation state and the removal state, there is relative movement between the driving roller 1121 and the driven roller 1122, causing the driving roller 1121 and the driven roller 1122 to switch positions between the close state position and the far state position. Through the position switching, the cleaning track 1123 can be switched between the tensioned state and the relaxed state.

[0104] In an exemplary embodiment, the elastic tension structure includes:

[0105] A stop portion 1031, provided on one of the first retaining ring 101 and the second retaining ring 102;

[0106] A connecting arm 1021, provided on the other of the first retaining ring 101 and the second retaining ring 102. A limiting portion 1041 is provided at one end of the connecting arm 1021 after passing through the stop portion 1031;

[0107] An elastic member, provided between the stop portion 1031 and the limiting portion 1041.

[0108] Exemplarily, the stop portion 1031 can be a part of the first retaining ring 101 or the second retaining ring 102. The stop portion 1031 can also be an independent component installed on the first retaining ring 101 or the second retaining ring 102 to meet different requirements.

[0109] Exemplarily, the limiting portion 1041 can be a part of the connecting arm 1021, and the limiting portion 1041 can also be an independent component installed on the connecting arm 1021 to meet different requirements.

[0110] It should be noted that the settings of the stop portion 1031 and the limiting portion 1041 form an installation position for the elastic member between the two, facilitating the installation of the elastic member. The setting of the elastic member can change the positional relationship between the driving roller 1121 and the driven roller 1122 by driving the position change between the limiting portion 1041 and the stop portion 1031, enabling the driving roller 1121 and the driven roller 1122 to switch from the far state position to the close state position.

[0111] In an exemplary embodiment, the connecting arm 1021 is movably connected to the stop portion 1031 so that the driving roller 1121 and the driven roller 1122 can approach or move away from each other; the elastic member causes the driving roller 1121 and the driven roller 1122 to maintain a movement tendency of approaching each other.

[0112] In this embodiment, there is no fixed connection between the connecting arm 1021 and the stop portion 1031. Instead, a movable connection is adopted so that relative movement can be achieved between the connecting arm 1021 and the stop portion 1031, and thus relative movement between the driving roller 1121 and the driven roller 1122 can be achieved.

[0113] In an exemplary embodiment, a buckle 103 is detachably connected to the first snap ring 101.

[0114] Exemplarily, a connecting groove is provided on the first snap ring 101, the buckle 103 is arranged in the connecting groove, and a stop portion 1031 is provided on the buckle 103.

[0115] It should be noted that the buckle 103 and the first snap ring 101 are detachably connected to facilitate the assembly of the connecting arm 1021, the elastic member, etc. The setting of the stop portion 1031 is to realize the installation limit of the elastic member.

[0116] In an exemplary embodiment, a movable groove 1011 is provided in the buckle 103, the connecting arm 1021 extends into the movable groove 1011 and is movably connected to the movable groove 1011. A limiting member 104 is provided at the end of the connecting arm 1021, and a limiting portion 1041 is located on the limiting member 104; the elastic member includes a compression spring 105, and both ends of the compression spring 105 are respectively abutted against the stop portion 1031 and the limiting portion 1041.

[0117] During the installation process of the cleaning assembly 112, the driving roller 1121 moves away from the driven roller 1122, the connecting arm 1021 extends outwards towards the outside of the movable groove 1011, the stop portion 1031 and the limiting portion 1041 approach each other, so that the compression spring 105 is compressed and stores energy. After the cleaning assembly 112 is removed, the compression spring 105 is released, the stop portion 1031 and the limiting portion 1041 move away under the elastic action of the compression spring 105, and the connecting arm 1021 moves towards the inside of the movable groove 1011, so that the driving roller 1121 and the driven roller 1122 approach each other.

[0118] It should also be noted that the connection relationship between the compression spring 105 and the stop portion 1031 and the limiting portion 1041 is not limited to abutment, and can also be detachable connection methods such as clamping and fixed connection methods such as welding.

[0119] Refer to the attached Figure 3 As shown, in an exemplary embodiment, the elastic tension structure includes a tension spring 106, and the tension spring 106 connects the first snap ring 101 and the second snap ring 102.

[0120] In this embodiment, the tension spring 106 is provided to make the first snap ring 101 and the second snap ring 102 tend to approach each other. Since the first snap ring 101 is installed on the driving roller 1121 and the second snap ring 102 is installed on the driven roller 1122, the driving roller 1121 and the driven roller 1122 will approach each other as the first snap ring 101 and the second snap ring 102 approach. Compared with the setting of the connecting arm 1021, the buckle 103, etc., the structure is simpler and the required cost is lower.

[0121] In an exemplary embodiment, a first mounting groove is provided in the circumferential direction of the driving roller 1121, and a second mounting groove is provided in the circumferential direction of the driven roller 1122. The first snap ring 101 is installed in the first mounting groove through the first bearing 107, and the second snap ring 102 is installed in the second mounting groove through the second bearing 108.

[0122] It should be noted that the first bearing 107 and the second bearing 108 are provided to enable the driving roller 1121 and the driven roller 1122 to rotate relative to the mounting bracket 13.

[0123] Refer to the attached Figure 4 As shown, the present application also provides a crawler mechanism, which is arranged on the floor brush 1. The floor brush 1 is provided with a mounting bracket 13. The crawler mechanism includes:

[0124] A crawler cleaning unit 11, including a driving component 111 and a cleaning component 112. The cleaning component 112 is detachably connected to the mounting bracket 13. The cleaning component 112 includes a driving roller 1121, a driven roller 1122, and a cleaning crawler 1123. The cleaning crawler 1123 is sleeved on the driving roller 1121 and the driven roller 1122;

[0125] A pulling belt 12, which is located inside the cleaning crawler 1123 and is sleeved on the driving roller 1121 and the driven roller 1122, provides a pulling force for the driving roller 1121 and the driven roller 1122 to approach each other, and transmits power from the driving roller 1121 to the driven roller 1122.

[0126] When removing the cleaning component 112, first remove the cleaning component 112 from the mounting bracket 13. The driving roller 1121 and the driven roller 1122 approach each other under the elastic action of the pulling belt 12, so that the cleaning crawler 1123 tensioned by the driving roller 1121 and the driven roller 1122 becomes loose. Then, the cleaning crawler 1123 can be removed from the driving roller 1121 and the driven roller 1122, effectively increasing the convenience of removing the cleaning crawler 1123.

[0127] When assembling the cleaning assembly 112, first put the cleaning track 1123 over the driving roller 1121 and the driven roller 1122 that are close to each other, and then install the driving roller 1121 and the driven roller 1122 at the corresponding positions on the mounting bracket 13. Due to the limitation of the mounting positions on the mounting bracket 13, the driving roller 1121 and the driven roller 1122 are separated against the elastic force of the tension belt 12, and the cleaning track 1123 is tensioned. During the installation process of the cleaning track 1123, the driving roller 1121 and the driven roller 1122 are close to each other under the elastic action of the tension belt 12, which facilitates putting the cleaning track 1123 over the driving roller 1121 and the driven roller 1122, and increases the installation convenience of the cleaning track 1123.

[0128] It should be noted that compared with the way of setting the connecting bracket 10, both the way of setting the tension belt 12 and the way of setting the connecting bracket 10 can make the driving roller 1121 and the driven roller 1122 close to each other. However, relatively speaking, the way of setting the tension belt 12 can effectively simplify the structure.

[0129] In an exemplary embodiment, a first installation groove is provided in the circumferential direction of the driving roller 1121, a second installation groove is provided in the circumferential direction of the driven roller 1122, and the tension belt 12 is arranged in the first installation groove and the second installation groove.

[0130] It should be noted that the first installation groove and the second installation groove are provided to install the tension belt 12 and reduce the possibility of the tension belt 12 moving along the axis of the driving roller 1121 or the driven roller 1122.

[0131] In an exemplary embodiment, a first guiding portion is provided on the inner surface of the tension belt 12 along the length direction, and a second guiding portion matching the first guiding portion is provided in the circumferential direction of the first installation groove and the second installation groove.

[0132] In this embodiment, the first guiding portion and the second guiding portion are provided to further reduce the possibility of the tension belt 12 running off track.

[0133] Exemplarily, the first guiding portion can be a rib, and the second guiding portion can be a groove matching the rib.

[0134] Exemplarily, multiple first guiding portions and second guiding portions can be provided.

[0135] In an exemplary embodiment, the thickness of the tension belt 12 is greater than the depth of the first installation groove and the depth of the second installation groove, and the outer surface of the tension belt 12 protrudes from the roller surfaces of the driving roller 1121 and the driven roller 1122 and contacts the inner surface of the cleaning track 1123.

[0136] In the prior art, in order to prevent the cleaning track 1123 from shifting on the driving roller 1121 and the driven roller 1122, a rubber layer (or called rubber coating) for increasing friction is often provided on the driving roller 1121 and the driven roller 1122. However, in this solution, there is no need to provide a rubber layer on the driving roller 1121 and the driven roller 1122. By contacting the outer surface of the pulling belt 12 with the inner surface of the cleaning track 1123, the frictional force between the outer surface of the pulling belt 12 and the inner surface of the cleaning track 1123 can reduce the possibility of the cleaning track 1123 slipping and moving around, which is beneficial to the stable operation of the cleaning track 1123. At the same time, canceling the rubber layer on the driving roller 1121 and the driven roller 1122 reduces the consumables and lowers the cost.

[0137] In addition, the setting of the pulling belt 12 also plays a role in evenly driving the track to rotate. And there is no need to set transmission teeth between the cleaning track and the driving roller and the driven roller. The cleaning track can be driven by the friction between the pulling belt 12 and the driving roller 1121 and the driven roller 1122. Compared with setting transmission teeth, the structure is simplified and the processing difficulty is reduced.

[0138] In an exemplary embodiment, a plurality of pulling belts 12 are axially arranged along the driving roller 1121 and the driven roller 1122.

[0139] It should be noted that the number of the pulling belts 12 can be set according to requirements. It can be two, three, five or more.

[0140] In an exemplary embodiment, the roller surfaces of the driving roller 1121 and the driven roller 1122 are smooth surfaces.

[0141] It should be noted that, in order to increase the friction between the driving roller 1121, the driven roller 1122 and the cleaning track 1123, in the prior art, first teeth are often provided on the driving roller 1121 and the driven roller 1122, and second teeth meshing with the first teeth are provided on the cleaning track 1123. In this embodiment, due to the setting of the pulling belt 12, the friction between the driving roller 1121, the driven roller 1122 and the cleaning track 1123 can be effectively increased, and there is no need to additionally set teeth. Therefore, the driving roller 1121 or the driven roller 1122 in this embodiment can be a smooth surface.

[0142] Exemplarily, the pulling belt 12 is made of materials such as rubber or silica gel.

[0143] In an exemplary embodiment, there are an installation state and a removal state between the cleaning assembly 112 and the mounting bracket 13. In the installation state, the driving roller 1121 and the driven roller 1122 are installed on the mounting bracket 13 and can rotate along their own axes; in the removal state, the driving roller 1121 and the driven roller 1122 are separated from the mounting bracket 13.

[0144] It should be noted that since the cleaning assembly 112 is detachable from the mounting bracket 13, the cleaning assembly 112 and the mounting bracket 13 have an installed state and a removed state. In the installed state, the driving roller 1121 and the driven roller 1122 are respectively installed on the mounting bracket 13, and the cleaning track 1123 is tensioned by the driving roller 1121 and the driven roller 1122. In the removed state, the driving roller 1121 and the driven roller 1122 are separated from the mounting bracket 13, and the driving roller 1121 and the driven roller 1122 approach each other under the elastic action of the pulling belt 12, so that the cleaning track 1123 can be separated from the driving roller 1121 and the driven roller 1122.

[0145] In an exemplary embodiment, there is a close state position and a far state position between the driving roller 1121 and the driven roller 1122. In the removed state, the driving roller 1121 and the driven roller 1122 approach each other under the elastic action of the pulling belt 12 and reach the close state position; in the installed state, the driving roller 1121 and the driven roller 1122 are far away from each other and reach the far state position.

[0146] It should be noted that in the removed state, the driving roller 1121 and the driven roller 1122 are removed from the mounting bracket 13 together. Due to the setting of the pulling belt 12, the driving roller 1121 and the driven roller 1122 approach each other and reach the close state position, making the originally tensioned cleaning track 1123 loose, which is convenient for the disassembly and assembly of the cleaning track 1123. In the installed state, the driving roller 1121 and the driven roller 1122 are installed on the mounting bracket 13 and are limited to the far state position by the mounting bracket 13. The driving roller 1121 and the driven roller 1122 are far away from each other, and the cleaning track 1123 is tensioned by the driving roller 1121 and the driven roller 1122 for easy cleaning.

[0147] Refer to the attached Figure 5 to the attached Figure 9 As shown, the present application provides a floor brush 1, including a housing 14, a mounting bracket 13 and a track mechanism, and the track mechanism is installed on the mounting bracket 13.

[0148] In this embodiment, the setting of the housing 14 can protect the track mechanism and the like. The setting of the mounting bracket 13 facilitates the installation of the track mechanism. The setting of the track mechanism can increase the cleaning area and reduce hair entanglement compared with using a rotary brush.

[0149] Exemplarily, the cleaning track 1123 includes an inner layer in contact with the driving roller 1121 and the driven roller 1122 and an outer layer for contacting a cleaning surface such as the ground. The inner layer can be made of materials such as rubber, and the outer layer is a cleaning flannel.

[0150] In an exemplary embodiment, the mounting bracket 13 includes a first side plate 133 and a second side plate 134. The first side plate 133 is fixed to the housing 14, and the second side plate 134 is detachably connected to the housing 14. The cleaning assembly 112 is detachably mounted between the first side plate 133 and the second side plate 134.

[0151] It should be noted that the cleaning assembly 112 is detachably mounted on the first side plate 133 and the second side plate 134. In order to enable the cleaning assembly 112 to move with the second side plate 134, after the cleaning assembly 112 is separated from the first side plate 133, the cleaning assembly 112 needs to remain connected to the second side plate 134.

[0152] In an exemplary embodiment, the driving component 111 is mounted on the first side plate 133. The first side plate 133 is further provided with a docking portion 131 for docking the driving roller 1121 and the driven roller 1122. The driving roller 1121 and the driven roller 1122 are detachably mounted on the docking portion 131 and can rotate respectively along their own axes.

[0153] Exemplarily, the driving component 111 is mounted on the corresponding docking portion 131, and the driving roller 1121 is sleeved outside the docking portion 131 and the driving component 111.

[0154] In this embodiment, the first side plate 133 and the driving roller 1121 and the driven roller 1122 are detachably connected by a docking method. The docking portion 131 is respectively provided corresponding to the driving roller 1121 and the driven roller 1122, and can be set as a convex portion on the first side plate 133. A third bearing 113 is provided between the outer wall of the docking portion 131 or the driving component 111 and the driving roller 1121, and a fourth bearing 114 is provided between the docking portion 131 and the driven roller 1122 to facilitate the rotation of the driving roller 1121 and the driven roller 1122.

[0155] Exemplarily, the driving component 111 can be fixedly mounted or detachably mounted to meet different requirements.

[0156] In an exemplary embodiment, the second side plate 134 is provided with a supporting portion 135 for the driving roller 1121 and the driven roller 1122. The driving roller 1121 and the driven roller 1122 are detachably mounted on the supporting portion 135 and can rotate respectively along their own axes.

[0157] It should be noted that the supporting portion 135 is respectively provided corresponding to the driving roller 1121 and the driven roller 1122, and the setting position of the supporting portion 135 needs to ensure that the cleaning track 1123 can be tensioned after the driving roller 1121 and the driven roller 1122 are installed.

[0158] Exemplarily, a third bearing 113 is provided between the supporting portion 135 and the driving roller 1121, and a fourth bearing 114 is provided between the supporting portion 135 and the driven roller 1122 to facilitate the rotation of the driving roller 1121 and the driven roller 1122.

[0159] It should also be noted that if the driving roller 1121 is butted against both the first side plate 133 and the second side plate 134, it is necessary to ensure that the splitting resistance (such as the frictional force of interference fit) between the driving roller 1121 and the second side plate 134 is greater than the splitting resistance between the driving roller 1121 and the first side plate 133 to ensure that the driving roller 1121 can move with the second side plate 134. Similarly, the splitting resistance between the driven roller 1122 and the second side plate 134 needs to be greater than the splitting resistance between the driven roller 1122 and the first side plate 133 to ensure that the driven roller 1122 can move with the second side plate 134.

[0160] In this embodiment, by pulling the second side plate 134 to drive the cleaning assembly 112 to act, and in a pulling manner, the cleaning assembly 112 is pulled out of the housing 14 to facilitate the disassembly and assembly of the cleaning assembly 112.

[0161] In an exemplary embodiment, a docking port 11211 is provided inside the driving roller 1121. The docking port 11211 is used to dock with the output end of the driving component 111 so that the driving roller 1121 can rotate under the drive of the driving component 111.

[0162] It is worth noting that the driving component 111 is installed on the first side plate 133. When the cleaning assembly 112 is removed, the driving component 111 is separated from the driving roller 1121. When the cleaning assembly 112 is reinstalled, if the driving component 111 is to drive the driving roller 1121 to act, the output end of the driving component 111 needs to be docked with the driving roller 1121 to drive the driving roller 1121 to act. Therefore, the docking port 11211 is provided inside the driving roller 1121.

[0163] Exemplarily, the driving component 111 is a motor.

[0164] Exemplarily, the driving component 111 and the docking port 11211 are connected by a spline.

[0165] It should also be noted that the driving component 111 is installed inside the driving roller 1121, and by reasonably utilizing the space, the overall volume of the floor brush 1 is reduced.

[0166] In an exemplary embodiment, a handle 132 and a storage groove are provided on the second side plate 134. The handle 132 can rotate and be stored in the storage groove.

[0167] In this embodiment, the handle 132 is provided to facilitate the pulling out of the second side and the cleaning assembly 112. The storage groove is provided to facilitate the storage of the handle 132, avoiding the handle 132 occupying external space and affecting the cleaning work of the floor brush 1.

[0168] In an exemplary embodiment, there are two sets of track mechanisms, and the track mechanisms are distributed at both ends of the housing 14.

[0169] In this embodiment, the setting of the two sets of track mechanisms can further increase the cleaning area, increase the ground pressure, and improve the cleaning efficiency.

[0170] In an exemplary embodiment, the two sets of track mechanisms are installed on the same second side plate 134;

[0171] Or

[0172] On the housing 14, second side plates 134 are respectively provided corresponding to the two sets of track mechanisms, and the track mechanisms are respectively installed on the corresponding second side plates 134.

[0173] In this embodiment, when the two sets of track mechanisms are installed on the same second side plate 134, the two sets of track mechanisms can be pulled out for disassembly and assembly operations when pulling the second side. If the two sets of track mechanisms are respectively installed on different second side plates 134, the corresponding second side plates 134 need to be respectively operated to achieve the disassembly and assembly operations of the corresponding track mechanisms.

[0174] Refer to the appendix Figure 7 As shown, in an exemplary embodiment, an adsorption channel 141 is provided in the housing 14. The opening of the adsorption channel 141 is provided between the two sets of track mechanisms. Along the opening of the adsorption channel 141, a scraping rack 142 is provided. The scraping rack 142 is located on the surface of the cleaning track 1123 and has a matching shape.

[0175] It should be noted that the adsorption channel 141 is provided between the two sets of track mechanisms. Compared with being provided at the front and rear ends of the floor brush 1, the adsorption wind force is more concentrated, reducing the suction loss, and also playing a role in reducing the occupied volume of the adsorption channel 141. The setting of the scraping rack 142 serves to clean the surface of the cleaning track 1123. The shape of the scraping rack matches the surface shape of the cleaning track 1123 to increase the cleaning ability of the cleaning track 1123.

[0176] Exemplarily, the middle of the opening of the adsorption channel 141 is located in the middle of the housing 14, facing the gap between the two sets of crawler mechanisms, and is arranged along the length direction of the driving roller 1121 or the driven roller 1122. And from the middle towards the extending direction, the opening of the adsorption channel 141 gradually decreases. The scraping rack is arranged along the edge of the opening of the adsorption channel 141, and has a radian matching the surface shape of the tensioned cleaning crawler 1123, achieving smooth contact with the cleaning crawler and reducing the possibility of damaging the cleaning crawler. And from the middle of the opening of the adsorption channel 141 to the edge direction of the housing 14, the distance between the scraping rack 142 and the ground gradually decreases, so as to adsorb the scraped dirt and reduce the possibility of hair entanglement. A plurality of scraping teeth are arranged on the scraping rack 142, and there is an interference amount between the scraping teeth and the cleaning crawler 1123 to increase the cleaning ability of the cleaning crawler 1123.

[0177] Exemplarily, the scraping rack is made of plastic, metal or ceramic.

[0178] Reference attached Figure 10 As shown in the figure, the present application provides a cleaning device, including a body 2 and a floor brush 1, and the body 2 is installed on the floor brush 1.

[0179] In this embodiment, the body 2 is arranged to facilitate the operation of the floor brush 1.

[0180] Exemplarily, the body 2 includes a push rod, a fresh water tank, a sewage tank and a suction power mechanism arranged on the push rod. The suction port of the suction power mechanism is communicated with the sewage tank, and the sewage tank is communicated with the adsorption channel 141. The fresh water tank is arranged to provide fresh water for the crawler cleaning unit 11 to clean the ground. The sewage tank is arranged to store sewage and ground garbage. The suction power mechanism is arranged to provide power for sucking sewage and garbage into the sewage tank.

[0181] Exemplarily, the suction power mechanism is arranged on the top of the sewage tank, and the suction port of the suction power mechanism is communicated with the top of the sewage tank.

[0182] Exemplarily, the suction power mechanism includes a suction fan, etc. Through negative pressure suction, the cleaned sewage, etc. are sucked into the sewage tank.

[0183] Reference attached Figure 11 As shown in the figure, the present application provides a cleaning system, including the cleaning device, and a base 3 or a base station. The base 3 or the base station is used to place the cleaning device.

[0184] It should be noted that the base 3 is used to place the cleaning device, and in addition to the placement function, the base station can also realize functions such as drying the cleaning crawler 1123, charging the floor brush 1, and automatically supplying and draining water for the fresh water tank and the sewage tank.
