Description

Technical Field

[0001] This invention belongs to the field of cleaning equipment technology, and specifically relates to a multi-functional floor scrubber base station. Background Technology

[0002] A floor scrubber is a common type of floor cleaning equipment. It typically includes a wastewater tank, a clean water tank, and a roller brush assembly and rollers located at the bottom. The rollers facilitate the floor scrubber's movement on the floor, and the roller brush assembly is equipped with roller brushes. Water is supplied to the roller brushes through the clean water tank, and the roller brushes scrub the floor. During the scrubbing process, stains and small solid debris on the floor are absorbed into the roller brushes, forming turbid wastewater containing solid debris. Then, a power mechanism creates a vacuum to collect the wastewater and solid debris from the roller brushes back into the wastewater tank inside the machine, thus preventing wastewater from spreading on the floor and completing the floor scrubbing work.

[0003] After cleaning the floor, the floor scrubber needs to empty its wastewater tank to remove waste and solid waste, and it also needs to be recharged. A floor scrubber base station is the device that performs these functions. It uses a suction mechanism to draw back the dry and wet waste from the wastewater tank and charges the scrubber via a power interface, enabling repeated cleaning. However, existing floor scrubber base stations are often too simple in structure, have limited functionality, and are inconvenient to use.

[0004] For example, the existing patent with publication number CN215502821U discloses a base station, including a base station body, a cleaning base, a water injection system, and a wastewater recycling system. The base station body has a receiving tank, the cleaning base is installed in the receiving tank, the cleaning base has a cleaning tank, the cleaning tank has an inlet connected to the water outlet of the water injection system, and the cleaning tank also has an outlet connected to the water inlet of the wastewater recycling system. This patent can solve the technical problem of excessive water consumption in existing base stations, but because it only includes a cleaning base, a water injection system, and a wastewater recycling system, it can only realize the recycling of wastewater from the floor scrubber and the cleaning of the floor scrubber, which is not convenient for the placement and fixation of the floor scrubber and is not convenient to use. Summary of the Invention

[0005] To solve the above problems, the primary objective of this invention is to provide a multifunctional floor scrubber base station, which can facilitate the placement and fixation of the floor scrubber and has multifunctional usage effects.

[0006] Another objective of this invention is to provide a multifunctional floor scrubber base station that facilitates the back-suction of wastewater from the floor scrubber's wastewater tank and enables the separation of dry and wet waste in the wastewater tank, achieving the classified treatment of solid waste and wastewater, which is more environmentally friendly and efficient.

[0007] Another objective of this invention is to provide a multifunctional floor scrubber base station that can automatically inject water and spray water evenly, effectively ensuring the cleaning efficiency of the floor scrubber's roller brush.

[0008] The final objective of this invention is to provide a multifunctional floor scrubbing machine base station with functions such as drying, portable sewage discharge, and automatic sewage discharge.

[0009] To achieve the above objectives, the technical solution of the present invention is as follows:

[0010] This invention provides a multifunctional floor scrubber base station, including a base station body. The base station body is equipped with a wastewater back-suction system for treating wastewater from the floor scrubber body and a self-cleaning system for cleaning the floor scrubber. The lower end of the base station body is also equipped with a base assembly for supporting the floor scrubber. The base station body, wastewater back-suction system, self-cleaning system, and base assembly together form a semi-enclosed structure for housing the floor scrubber.

[0011] Furthermore, the base assembly includes a base and a base cover plate. The base cover plate is installed on the upper end of the base. The base includes a supporting base plate and base side plates. The base side plates are arranged on both sides of the supporting base plate to form bearing grooves that are compatible with the roller brush assembly and rollers of the floor scrubber. The roller brush assembly and rollers of the floor scrubber are arranged in the bearing grooves and are limited by the base cover plate.

[0012] Furthermore, the bearing groove includes a roller brush rinsing groove disposed on the inner side of the base. The roller brush rinsing groove is configured with an arc-shaped structure adapted to the roller brush. A row of precision hanging teeth is disposed inside the roller brush rinsing groove, and a roller brush cleaning outlet is disposed at the bottom of the roller brush rinsing groove.

[0013] Furthermore, sealing wall panels are provided on the upper side of the supporting base plate and the lower side of the base cover plate.

[0014] Furthermore, the front end of the supporting base plate is connected to an integrally formed inclined plate. The upper end of the inclined plate is connected to the supporting base plate, and the lower end extends to the ground, forming a sloping structure for the rollers of the floor scrubber to slide into the bearing groove.

[0015] Furthermore, the angle between the inclined plate and the ground plane is less than 15 degrees, and the height of the upper end of the inclined plate from the ground plane is 37mm.

[0016] Furthermore, a limiting protrusion for blocking the scrubbing machine's rollers is provided at the connection between the supporting base plate and the inclined plate. The limiting protrusion is horizontally positioned higher than the front end of the inclined plate. When the scrubbing machine is pushed into the scrubbing machine's receiving position and parked, the limiting protrusion will be higher than the scrubbing machine's rollers, which can block the scrubbing machine's rollers in the bearing groove, prevent the scrubbing machine from moving backward, and improve the stability of the scrubbing machine in the base station.

[0017] Furthermore, the supporting base plate has a flat plate structure, with its horizontal position lower than the upper end of the inclined plate. The upper end of the limiting protrusion is flush with the upper end of the inclined plate, while the lower end of the limiting protrusion is higher than the supporting base plate. This design allows the supporting base plate and the limiting protrusion to form a downward slope structure slightly lower than the upper end of the inclined plate. When the rollers of the floor scrubber slide upward from the upper slope of the inclined plate, they can smoothly slide into the bearing groove from the lower slope structure, making it more convenient and labor-saving.

[0018] Furthermore, an assist roller is provided at the connection between the supporting base plate and the inclined plate. The assist roller is located in the middle and on both sides of the limiting protrusion, and the horizontal position of the assist roller is higher than the limiting protrusion. When the assist machine pushes the floor scrubber from the ground into the floor scrubber receiving position, the entire bottom of the floor scrubber can roll on the assist roller, which facilitates the brush entering the bearing groove. At the same time, the assist roller can also lift the entire bottom of the floor scrubber, which can prevent the middle position of the bottom of the floor scrubber from getting stuck at the upper end of the inclined plate. In addition, the assist roller can also allow the brush and the roller to slide in contact at the connection between the inclined plate and the supporting base plate, avoiding the brush being suspended in the air, which would increase the difficulty of pushing the brush and the roller into the bearing groove.

[0019] Furthermore, a booster roller mounting groove is provided at the connection between the support base plate and the inclined plate. The booster roller is detachably installed in the booster roller mounting groove, and the two ends of the booster roller are respectively rotatably connected to the left and right side walls of the booster roller mounting groove.

A limiting member that cooperates with the valve catch is provided on the back side of both the first flip cover baffle and the second flip cover baffle. The valve catch can penetrate the flip cover bottom plate and move up and down to block or move away from the limiting member.

[0024] Furthermore, the bottom plate of the wet-dry separation box has an inclined plate structure, and the drainage hole is designed as a sloping funnel shape, which can accelerate the flow of sewage. At the same time, the negative pressure inside the sewage tank can also accelerate the filtration of sewage, effectively shortening the action time.

[0025] Furthermore, the wastewater tank includes a wastewater tank body and a wastewater tank cover. The wastewater tank cover closes onto the wastewater tank body to form a sealed space. A dry-wet separation box fixing groove is provided on the upper part of the wastewater tank body. The bottom of the dry-wet separation box is detachably installed in the dry-wet separation box fixing groove, and the main body of the dry-wet separation box is located inside the wastewater tank cover.

Above, a sewage outlet sealing ring is fixed on the sewage outlet transmission rod. The sewage outlet sealing ring seals above the sewage outlet and can move away from the sewage outlet as the sewage outlet transmission rod moves upward to open the sewage outlet. A through hole is provided at the bottom of the portable sewage control slot. The upper end of the sewage outlet transmission rod is movably set and passes through the through hole at the bottom of the portable sewage control slot, extending into the portable sewage control slot. An inclined groove is also provided on the sewage outlet transmission rod. An inclined piece adapted to the inclined groove is provided on the sewage button. The inclined piece is movably installed in the inclined groove and continuously abuts against the upper surface of the inclined groove. During the process of pressing and moving the sewage button into the portable sewage control slot, the inclined piece can move forward in the inclined groove and continuously push the inclined groove, thereby driving the sewage outlet transmission rod to move upward along the through hole at the bottom of the portable sewage control slot, so that the sewage outlet sealing ring moves away to open the sewage outlet. The rear of the inclined plate is also provided with a locking groove that matches the top surface of the inclined groove. When the rear of the inclined plate enters the inclined groove, the top surface of the inclined groove engages with the locking groove, so that the drain button and the drain port transmission rod form a mutually supporting fixed structure. The side of the drain port transmission rod is also provided with an inclined surface, and the side of the reset rod is also provided with a triangular block that matches the inclined surface.

[0058] Furthermore, the first heating element includes a PTC heating element, and both the upper and lower shells of the mounting bracket are made of high-temperature resistant materials. The upper and lower shells seal the fan, PTC heating element, and first NTC temperature sensor. The fan outlet and inlet are both located on the upper shell. The DC fan blows hot air from the outlet through the steel mesh onto the PTC heating element, and the air in the dust bag is then drawn back into the inlet, achieving internal air circulation and ensuring uniform heating and drying throughout the dust bag. The NTC temperature sensor prevents the PTC heating element from overheating, thus stopping the machine from supplying power to the PTC heating element.

[0059] Furthermore, the second hot air drying mechanism includes a DC blower, a second heating block, and a heating block mounting bracket.

The full water level sensor is located above the clean water storage compartment, and the low water level sensor is located at the bottom of the compartment. The pump and the full water level sensor are both electrically connected to the conductive sheet. A contact-type power supply contact is provided on the main body of the base station. A conductive spring pin through-hole is also provided at the bottom of the clean water tank main body, through which the conductive spring pin passes and connects electrically to the contact-type power supply contact. In this application, the clean water tank is installed on the base station body and can be lifted at will. When the clean water tank is put back on the base station body, the conductive pin can be electrically connected to the contact power supply contact, and power is supplied to accessories such as the liquid pump and the water level sensor through the external power supply of the base station body.

[0067] Furthermore, the main body of the clean water tank is also provided with a partition plate for separating the cleaning liquid storage tank and the clean water storage tank. The partition plate is provided with a conductive component mounting groove. The contact conductive component is installed in the conductive component mounting groove, and the conductive spring pin through hole is provided on the bottom plate of the conductive component mounting groove.

[0068] Furthermore, a pump room is also provided inside the clean water tank cover, and a pump room cover plate is provided at the bottom of the pump room. The liquid pump is installed inside the pump room and sealed by the pump room cover plate.

[0069] Furthermore, the water tank lid is also equipped with a leather strap handle and a rotatable plastic handle for storage.

The plastic handle can be rotated upright for carrying or rotated flat for storage in the storage compartment.

[0070] Furthermore, a clean water inlet pipe is provided at the bottom of the main body of the clean water tank. A first outlet flow-stopping and guiding component is installed on the clean water inlet pipe. The first outlet flow-stopping and guiding component includes a first flow-stopping transmission rod, a first water inlet sealing ring, and a first guide seat. The first flow-stopping transmission rod is movably disposed inside the clean water inlet pipe. The first water inlet sealing ring is fixedly installed on the upper end of the first flow-stopping transmission rod and seals the clean water inlet pipe. The first guide seat is fixedly installed on the main body of the base station and is disposed directly below the first flow-stopping transmission rod. A first flow-stopping transmission rod return spring is also sleeved on the first flow-stopping transmission rod. One end of the first flow-stopping transmission rod return spring abuts against the lower end of the first flow-stopping transmission rod, and the other end abuts against the clean water inlet pipe. A first water pipe connector communicating with the automatic water injection mechanism is provided on the first guide seat. A first central top column that can be detachably contacted with the first flow-stopping transmission rod is also provided inside the first guide seat. In this application, when the clean water tank is placed on the base station body, the first flow-stopping transmission rod can be lifted by the first central top column inside the first flow guide seat. During the lifting process, the return spring of the first flow-stopping transmission rod is compressed, which simultaneously drives the first water inlet sealing ring to move upward, disengaging it from the clean water inlet interface pipe. This allows the clean water tank body and the first flow guide seat to connect, enabling the automatic water injection mechanism to inject water into the clean water tank through the first water pipe connector on the first flow guide seat. When the clean water tank leaves the base station body, the first flow-stopping transmission rod disengages from the first central top column, and the return spring of the first flow-stopping transmission rod resets, causing the first flow-stopping transmission rod and the first water inlet sealing ring to move downward. The first water inlet sealing ring then re-seals the clean water inlet interface pipe, preventing leakage from the clean water inlet interface pipe.

[0071] Furthermore, a first upper abutment protrusion is provided on the inner wall of the clean water inlet pipe, and a first lower abutment protrusion is provided on the first flow-stopping transmission rod. The upper end of the return spring of the first flow-stopping transmission rod abuts against the first upper abutment protrusion, and the lower end abuts against the first lower abutment protrusion.

[0072] Furthermore, a clean water outlet interface pipe is provided at the bottom of the main body of the clean water tank. A second water outlet flow-stopping and guiding assembly is installed on the clean water outlet interface pipe. The second water outlet flow-stopping and guiding assembly includes a second flow-stopping transmission rod, a second water inlet sealing ring, and a second flow guide seat. The second flow-stopping transmission rod is movably disposed inside the clean water outlet interface pipe. The second water inlet sealing ring is fixedly installed on the upper end of the second flow-stopping transmission rod and seals the clean water outlet interface pipe. The second flow guide seat is fixedly installed on the main body of the base station and is located directly below the second flow-stopping transmission rod. A second flow-stopping transmission rod return spring is also sleeved on the second flow-stopping transmission rod. One end of the second flow-stopping transmission rod return spring abuts against the lower end of the second flow-stopping transmission rod, and the other end abuts against the clean water outlet interface pipe. A second water pipe connector connected to the clean water tank outlet pipe is provided on the second flow guide seat. A second central top column that can be detachably contacted with the second flow-stopping transmission rod is also provided inside the second flow guide seat. In this application, when the clean water tank is placed on the base station body, the second flow-stopping transmission rod can be lifted by the second central top column inside the second flow guide seat. During the lifting process, the return spring of the second flow-stopping transmission rod is compressed, which simultaneously drives the second water outlet sealing ring to move upward, disengaging it from the clean water outlet interface pipe. This allows the clean water tank body and the second flow guide seat to connect, enabling the clean water tank to discharge water to the clean water tank outlet pipe through the second water pipe joint on the second flow guide seat. When the clean water tank leaves the base station body, the second flow-stopping transmission rod disengages from the second central top column, and the return spring of the second flow-stopping transmission rod resets, causing the second flow-stopping transmission rod and the second water outlet sealing ring to move downward. The second water outlet sealing ring then reseals the clean water outlet interface pipe, preventing leakage from the clean water outlet interface pipe.

[0073] Furthermore, a second upper abutment protrusion is provided on the inner side wall of the clean water outlet pipe, and a second lower abutment protrusion is provided on the second flow-stopping transmission rod. The upper end of the return spring of the second flow-stopping transmission rod abuts against the second upper abutment protrusion, and the lower end abuts against the second lower abutment protrusion.

[0074] Furthermore, the automatic water injection mechanism includes a water control solenoid valve, a pressure reducing valve, a quick-connect water pipe head, an adapter, and an automatic water injection pipeline. The water control solenoid valve, pressure reducing valve, quick-connect water pipe head, adapter, automatic water injection pipeline, first outlet flow-stopping and guiding component, and clean water tank are connected sequentially. The full water level sensor and the low water level sensor are both used in conjunction with the water control solenoid valve. In this application, the automatic water injection mechanism automatically injects clean water used for self-cleaning into the base station without human intervention. The process is as follows: water is controlled by the water control solenoid valve, and the pressure reducing valve stabilizes the pressure, injecting tap water into the clean water tank. When the low water level sensor detects that there is no water in the clean water tank, the low water level sensor at the bottom of the clean water tank releases an electrical signal to the solenoid valve, causing the solenoid valve to release tap water into the clean water tank. When the clean water tank is full, the full water level sensor inside the clean water tank detects this and releases an electrical signal to the solenoid valve to stop working.

[0075] Furthermore, the automatic water injection mechanism also includes a solenoid valve protection box, which includes a detachably connected upper cover and a lower cover. The upper cover and the lower cover are assembled to form a solenoid valve receiving cavity, and the water control solenoid valve and the pressure reducing valve are both installed in the solenoid valve receiving cavity.

[0076] Furthermore, one end of the water outlet pipe of the clean water tank is connected to the second water pipe connector on the second guide seat, and the other end is connected to the inlet of the clean water pump. A three-way connector is installed on the outlet of the clean water pump. The cleaning pipeline includes a first cleaning pipe, a second cleaning pipe, and a third cleaning pipe. One end of each of the first, second, and third cleaning pipes is connected to the outlet of the clean water pump via a three-way connector. A double-body spray plate for spraying clean water into the roller brush rinsing tank is also installed on the base. The other ends of the first and second cleaning pipes are connected to the double-body spray plate, and the other end of the third cleaning pipe is connected to the wastewater tank of the floor scrubber. The clean water pump can self-clean the wastewater tank and roller brush of the floor scrubber separately with clean water through the cleaning pipeline, reducing the problem of mold and odor caused by wastewater residue.

[0077] Furthermore, the dual-body jet plate is provided with two sets of uniform water spray structures, which are located on the left and right sides of the dual-body jet plate respectively, forming a dual-body jet water spray structure that can cover the entire roller brush rinsing tank.

[0078] Furthermore, the uniform water spray structure includes a water inlet for the flyboard installed on the double-body flyboard, and a uniform flow channel disposed inside the double-body flyboard. The side of the double-body flyboard is provided with uniform water spray holes facing the roller brush rinsing tank. The ends of the first cleaning pipe and the second cleaning pipe away from the clean water pump are both connected to the water inlet for the flyboard. The uniform water spray holes are connected to the water inlet for the flyboard through the uniform flow channel.

[0079] Furthermore, the uniform flow channel includes a spray nozzle channel and a water flow channel. The inlet of the water flow channel is connected to the water inlet of the fly plate, and the water flow channel is provided with multiple outlets connected to the spray nozzle channel. Multiple uniform spray holes are provided, and one end of each of the multiple uniform spray holes is connected to the spray nozzle channel and is arranged at equal intervals and dispersedly in the water flow channel to achieve uniform water spraying.

[0080] Furthermore, the uniform water spray holes are tapered structures that gradually decrease in size from the inside out, which can pressurize the water flow and increase its impact force.

[0081] Furthermore, the water flow channels are provided in multiple interconnected manner, and each water flow channel forms a water storage tank capable of buffering clean water.

[0082] Furthermore, the inlet of the jet plate is also connected to a jet plate inlet connector, and the jet plate inlet is connected to the first cleaning pipe and the second cleaning pipe through the jet plate inlet connector.

[0083] Furthermore, the base is provided with a jet plate fixing hole on the side of the roller brush rinsing tank, the dual jet plate is installed on the jet plate fixing hole, and the uniform water spray hole is located on the upper side of the roller brush rinsing tank, so that the arc-shaped water flow sprayed from the uniform water spray hole is sprayed into the roller brush rinsing tank.

[0084] Furthermore, the dual-body flying stream plate includes a dual-body flying stream front shell and a dual-body flying stream rear shell.

[0085] Furthermore, the base station body is also equipped with a third cleaning pipe fixing groove, in which the third cleaning pipe is installed. A body-mounted clean water supply nozzle for spraying water onto the floor scrubber's wastewater tank is installed at the upper end of the third cleaning pipe fixing groove. The body-mounted clean water supply nozzle is connected to the end of the third cleaning pipe. In this application, the body-mounted clean water supply nozzle is approximately 260mm above the ground, directly facing the body-mounted clean water nozzle on the floor scrubber's wastewater tank. The clean water pump draws clean water and guides it to the third cleaning pipe and the uniform spray holes. When the machine returns to the base station, the body-mounted clean water nozzle on the floor scrubber's wastewater tank connects with the body-mounted clean water supply nozzle on the base station body, enabling the base station's clean water to be injected into the machine body for cleaning the wastewater tank. Simultaneously, the more than forty uniform spray holes above the roller brush rinsing tank can evenly spray water onto the floor scrubber's roller brush for self-cleaning. After the floor scrubber's wastewater tank and roller brush are cleaned, the return suction fan performs a third return suction to recycle the self-cleaned water back into the base station's wastewater tank.

[0086] Furthermore, a speaker is mounted on the bottom of the base, and the base also has a sound-transmitting hole on the side of the speaker. The speaker is controlled by a circuit board, enabling operation and voice feedback.

[0087] Furthermore, the base station body is also equipped with a circuit board, and other electronic components such as the fan are controlled, connected and powered by the circuit board, and transformed by a transformer to realize intelligent control of the whole machine.

[0088] Furthermore, the base station body is also equipped with control buttons. The control buttons can control the operation commands through the electronic control board, allowing for manual intervention of the base station, such as manual self-cleaning and manual hot air drying.

[0089] Furthermore, the base station body includes a wastewater tank mounting position on the left and a clean water tank mounting position on the right. The clean water tank is installed on the clean water tank mounting position, and the wastewater tank is installed on the wastewater tank mounting position. A dust collection bag mounting groove is provided between the wastewater tank mounting position and the clean water tank mounting position. The wastewater tank mounting position and the clean water tank mounting position protrude and wrap around the left and right sides of the dust collection bag mounting groove to form the receiving position for the floor scrubber. By installing the wastewater tank on the wastewater tank mounting position and the clean water tank on the clean water tank mounting position, a structure without an outer wall can be formed, which can significantly save materials and molds, and reduce the production cost of the product. At the same time, the rational placement of components on the base station body can facilitate the formation of airflow ducts and save space.

[0090] Furthermore, a power supply support plate is also provided on the housing of the floor scrubber, and a charging module for charging the floor scrubber is provided on the power supply support plate. When the floor scrubber returns to the base station, the charging module can connect to the charging terminals of the floor scrubber to charge the floor scrubber.

[0091] Furthermore, drainage holes are provided at the sewage tank installation location, the clean water tank installation location, and the power supply support plate. The drainage holes, guided by the ribs, allow the water to flow to the cleaning outlet of the roller brush on the base below, thus draining the water accumulated inside the base station body.

[0092] Furthermore, a dry-wet separation installation groove is provided between the dust collection bag installation groove and the sewage tank installation position, and the dry-wet separation installation side plate is fixed in the dry-wet separation installation groove.

[0093] Furthermore, the base station body is also provided with a first hot air drying mechanism mounting slot below the dust collection bag mounting slot. The first hot air drying mechanism mounting slot is connected to the dust collection bag mounting slot. The first hot air drying mechanism mounting slot can seal the first hot air drying mechanism inside the base station body and realize ventilation between the first hot air drying mechanism and the dust collection bag.

[0094] Furthermore, a ventilation plate is provided between the dust bag mounting slot and the first hot air drying mechanism mounting slot. The ventilation plate is positioned directly above the first hot air drying mechanism. A dust bag ventilation inlet is located in the center of the ventilation plate and is connected to the fan outlet. Dust bag ventilation outlets are located around the periphery of the ventilation plate and are connected to the fan inlet. A DC fan blows hot air from the fan outlet and the dust bag ventilation inlet onto the PTC heating block. The hot air is then drawn back from the dust bag through the dust bag ventilation outlet to the fan inlet, creating a sealed effect and achieving internal air circulation. This ensures that the entire dust bag space is evenly heated and dried.

[0095] Furthermore, the base station body also has a return suction fan mounting slot on the side of the dust bag mounting slot. A target support slot is located above the return suction fan mounting slot. The return suction fan is fixed within the return suction fan mounting slot. The target filter bracket and the HEPA filter are both located within the target support slot. A return suction air inlet is provided between the target support slot and the dust bag mounting slot. The return suction fan draws air from the dust bag in the dust bag mounting slot through the return suction air inlet, creating negative pressure.

[0096] Furthermore, the base station body has a UV lamp mounting slot between the dust bag mounting slot and the wastewater tank mounting position. The left and right sides of the UV lamp mounting slot are connected to the dust bag mounting slot and the wastewater tank mounting position, respectively. A UV germicidal lamp is installed inside the UV lamp mounting slot. The UV germicidal lamp can effectively sterilize the dust bag and wastewater tank with ultraviolet light, preventing bacterial growth and health risks. Simultaneously, placing the UV germicidal lamp between the dust bag mounting slot and the wastewater tank mounting position achieves a concealed design; operation can only commence after the dust collection cover is sealed and the wastewater tank is returned to its original position, ensuring safety and reliability.

[0097] Furthermore, the UV lamp mounting slot is also equipped with a UV tube for connecting to the floor scrubber's housing. The light from the UV germicidal lamp can pass through the UV tube to sterilize the wastewater tank of the floor scrubber in the housing.

[0098] Furthermore, a deodorizing and sterilizing module is also provided below the dust collection bag mounting slot, and a deodorizing ion sheet is installed inside the dust collection bag mounting slot. The deodorizing and sterilizing module is connected to the deodorizing ion sheet. This enables the dust collection bag to be sterilized and deodorized, preventing the generation of unpleasant odors.

[0099] Furthermore, the deodorizing and sterilizing module includes an ozone module and a silver ion module.

[0100] Compared with the prior art, the beneficial effects of the present invention are:

[0101] First, the multifunctional base station of the present invention is equipped with a base station body, a base assembly, a sewage back suction system, and a self-cleaning system, which can form a semi-enclosed receiving space, making it convenient to place and fix the floor scrubber. The sewage back suction system can automatically back suction the sewage on the floor scrubber's sewage tank and roller brush. The self-cleaning system can clean and sterilize the floor scrubber's roller brush and sewage tank after the sewage back suction treatment, which has a multifunctional effect and is convenient to use.

[0102] Secondly, the wastewater back-suction system of this multi-functional base station is equipped with a back-suction pipe, a wastewater tank, a dust collection bag, a back-suction fan, and a dry-wet separation device. The back-suction fan can suck the dry and wet waste in the floor scrubber back into the base station, and the dry-wet separation device can separate the dry and wet waste to achieve the classified treatment of solid waste and wastewater, which is more environmentally friendly and efficient.

[0103] In addition, the self-cleaning system of this multi-functional base station is equipped with an automatic water injection mechanism, a clean water tank, a clean water tank outlet pipe, a clean water pump, and a cleaning pipe, which can clean the floor scrubber's roller brush and wastewater tank. The end of the cleaning pipe is also equipped with a dual-body jet spray structure, which can spray water evenly and comprehensively on the roller brush rinsing tank, effectively ensuring the cleaning efficiency of the floor scrubber's roller brush.

[0104] Furthermore, the main body of this multi-functional base station is designed as a semi-enclosed structure without any outer walls, which not only facilitates the placement and fixing of the floor scrubbing machine, but also significantly saves materials and molds, reducing costs.

[0105] Finally, this multi-functional base station is also equipped with a hot air drying system, an automatic sewage discharge mechanism, a portable sewage discharge mechanism, and an automatic water filling mechanism. The hot air drying system can dry the dust collection bags of the base station and the scrubbing machine's roller brush with hot air, keeping the scrubbing machine's roller brush and the base station's dust collection bags dry when not in use, reducing bacterial growth and mold. The portable sewage discharge mechanism is installed at the bottom of the sewage tank and does not require electricity. It can be manually controlled to achieve portable sewage discharge from the scrubbing machine, making it more convenient and faster. The automatic sewage discharge mechanism realizes the automatic sewage discharge of the sewage tank through a sewage pump, making it more convenient and labor-saving. The automatic water filling mechanism can automatically detect the water level of the clean water tank and realize the automatic water filling of the clean water tank. Attached Figure Description

[0148] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0149] like Figure 1-33 As shown, the implementation of this embodiment is as follows:

[0150] This embodiment provides a multi-functional floor scrubber base station, including a base station body 1. The base station body 1 is equipped with a wastewater back-suction system 2 for treating wastewater from the floor scrubber 6 and a self-cleaning system 3 for cleaning the floor scrubber 6. A base assembly 4 for supporting the floor scrubber 6 is also installed at the lower end of the base station body 1. The base station body 1, wastewater back-suction system 2, self-cleaning system 3, and base assembly 4 together form a semi-enclosed floor scrubber housing 5. In this application, the floor scrubber 6 is placed in the floor scrubber housing 5 and supported and fixed by the base assembly 4. The wastewater back-suction system 2 back-suctions the wastewater from the floor scrubber 6. After the back-suction is completed, the self-cleaning system 3 rinses the wastewater tank and roller brush of the floor scrubber 6, achieving self-cleaning of the floor scrubber 6.

[0151] Furthermore, the base assembly 4 includes a base 41 and a base cover plate 42. The base cover plate 42 is installed on the upper end of the base 41. The base 41 includes a supporting base plate 411 and a base side plate 412. The base side plate 412 is arranged on both sides of the supporting base plate 411 to form a bearing groove 413 that is compatible with the roller brush assembly and rollers of the floor scrubber 6. The roller brush assembly and rollers of the floor scrubber 6 are arranged in the bearing groove 413 and are limited by the base cover plate 42.

[0152] Furthermore, the bearing trough 413 includes a roller brush rinsing trough 414 disposed inside the base 41. The roller brush rinsing trough 414 is configured with an arc-shaped structure adapted to the roller brush. A row of precision hanging teeth 415 is disposed inside the roller brush rinsing trough 414, and a roller brush cleaning outlet 416 is disposed at the bottom of the roller brush rinsing trough 414. The precision hanging teeth 415 can filter hair or other solid waste on the roller brush during roller self-cleaning, and the roller brush cleaning outlet 416 can guide the wastewater from cleaning the roller brush into the wastewater tank of the base station.

[0153] Furthermore, sealing wall panels are provided on the upper side of the support base plate 411 and the lower side of the base cover plate 42. When the floor scrubber 6 is pushed into the floor scrubber receiving position 5, the sealing wall panels can seal the roller brush in the bearing groove 413 from the upper and lower sides, isolating it from atmospheric pressure, so that negative pressure can be generated inside to remove dirt, and no odor will leak out during hot air drying.

[0154] Furthermore, an integrally formed inclined plate 417 is connected to the front end of the supporting base plate 411. The upper end of the inclined plate 417 is connected to the supporting base plate 411, and the lower end extends to the ground, forming a ramp-type structure for the rollers of the floor scrubber 6 to slide into the bearing groove 413. The ramp-type structure makes it easy to push the floor scrubber 6 directly from the ground into the bearing groove 413 of the base 41. Since the floor scrubber 6 is relatively heavy, compared with the traditional method of manually lifting and placing the floor scrubber 6 into the base station, the ramp-type method of this base station is more labor-saving and can reduce the collision between the floor scrubber 6 and the base station, thus extending the service life of both the base station and the floor scrubber 6.

[0155] Furthermore, the angle between the inclined plate 417 and the ground plane is less than 15 degrees, and the height of the upper end of the inclined plate 417 from the ground plane is 37mm.

[0156] Furthermore, a limiting protrusion 418 for blocking the rollers of the floor scrubber 6 is provided at the connection between the supporting base plate 411 and the inclined plate 417. The limiting protrusion 418 is horizontally higher than the front end of the inclined plate 417. When the floor scrubber 6 is pushed into the floor scrubber receiving position 5 and parked, the limiting protrusion 418 will be higher than the rollers of the floor scrubber 6, which can block the rollers of the floor scrubber 6 in the bearing groove 413, prevent the floor scrubber 6 from moving backward, and improve the stability of the floor scrubber 6 in the base station.

[0157] Furthermore, the support base plate 411 has a flat plate structure. The horizontal position of the support base plate 411 is lower than the upper end of the inclined plate 417. The upper end of the limiting protrusion 418 is flush with the upper end of the inclined plate 417, and the lower end of the limiting protrusion 418 is higher than the support base plate 411. With this arrangement, the support base plate 411 and the limiting protrusion 418 can form a downward slope structure slightly lower than the upper end of the inclined plate 417. When the roller of the floor scrubber 6 slides upward from the upward slope structure of the inclined plate 417, it can smoothly slide into the bearing groove 413 from the downward slope structure, which is more convenient and labor-saving.

[0158] Furthermore, an assisting roller 419 is provided at the connection between the supporting base plate 411 and the inclined plate 417. The assisting roller 419 is located in the middle and on both sides of the limiting protrusion 418, and the horizontal position of the assisting roller 419 is higher than that of the limiting protrusion 418. When the floor scrubber 6 is pushed from the ground into the floor scrubber receiving position, the entire bottom of the floor scrubber 6 can roll on the assisting roller 419, which facilitates the roller brush entering the bearing groove 413. At the same time, the assisting roller 419 can also lift the entire bottom of the floor scrubber 6 accordingly, which can prevent the middle position of the bottom of the floor scrubber 6 from getting stuck at the upper end of the inclined plate 417. In addition, the assisting roller 419 can also make the roller brush and the roller slide in contact at the connection between the inclined plate 417 and the supporting base plate 411, which can prevent the roller brush 62 from being suspended in the air and increase the difficulty of pushing the roller brush 62 and the roller into the bearing groove 413.

[0159] Furthermore, a support roller mounting groove is provided at the connection between the support base plate 411 and the inclined plate 417. The support roller 419 is detachably installed in the support roller mounting groove, and the two ends of the support roller 419 are respectively rotatably connected to the left and right side walls of the support roller mounting groove.

[0160] Furthermore, the wastewater back-suction system 2 includes a back-suction pipe 21, a wastewater tank 22, a dust collection bag 23, and a back-suction fan 24. The front end of the back-suction pipe 21 is connected to the wastewater tank back-suction outlet of the floor scrubber 6, and the rear end is connected to the wastewater tank 22. The dust collection bag 23 is located on the side of the wastewater tank 22. The back-suction fan 24, the dust collection bag 23, the wastewater tank 22, and the back-suction pipe 21 are sequentially connected to form a suction circuit 02 for back-suctioning dry and wet waste from the floor scrubber 6. In this application, the wastewater tank 22 is used to store wastewater from the wastewater tank of the floor scrubber 6, and the dust collection bag 23 is used to store solid waste from the wastewater tank of the floor scrubber 6. During the back suction, the back suction fan 24 generates negative pressure in the sealed wastewater tank 22, and the dry and wet waste in the wastewater tank of the floor scrubber 6 is sucked back to the upper part of the wastewater tank 22 through the suction circuit. The wastewater leaks into the wastewater tank below under its own gravity, and the fixed waste is sucked into the dust collection bag 23 by the suction generated by the back suction fan 24, thus realizing the back suction and separation of dry and wet waste in the wastewater tank of the floor scrubber 6.

[0161] Furthermore, the support base plate 411 is also provided with a passage 4111 for connecting to the back suction outlet of the wastewater tank of the floor scrubber 6. The front end of the back suction pipe 21 is located below the passage 4111 and is connected to the back suction outlet of the wastewater tank of the floor scrubber 6 through the passage 4111. The roller brush cleaning outlet 416 is located on the side of the passage 4111 and is located above the back suction pipe 21 and is connected to the front end of the back suction pipe 21. In this application, the back suction outlet of the wastewater tank of the floor scrubber is located at the bottom of the floor scrubber 6. When the floor scrubber 6 is parked in the floor scrubber housing 5, its wastewater tank back suction outlet is located directly above the front end of the back suction pipe 21. When the back suction fan 24 performs back suction, the dry and wet waste in its wastewater tank can enter the back suction pipe 21 through the passage 4111 to achieve back suction.

[0162] Furthermore, the wastewater back-suction system 2 also includes a wet-dry separation device 25, which includes a wet-dry separation box 251. The wet-dry separation box 251 is installed inside the wastewater tank 22 and located at the top of the wastewater tank 22. The rear end of the back-suction pipe 21 is connected to the wet-dry separation box 251. A drainage hole 252 is provided at the bottom of the wet-dry separation box 251. A wet-dry separation installation side plate 253 is also provided between the wet-dry separation box 251 and the dust collection bag 23. A solid waste back-suction port 254 with corresponding positions is provided on the side wall of the wet-dry separation box 251, the wastewater tank 22, and the wet-dry separation installation side plate 253. The solid waste back-suction ports 254 are connected to form a solid waste back-suction channel. The wet-dry separation box 251 and the dust collection bag 23 are connected to each other. The wastewater tank 22 and the dry-wet separation installation side plate 253 are connected through the solid waste back suction channel. The side walls of the wastewater tank 22 and the dry-wet separation installation side plate 253 are also provided with back suction airflow ports 255, and the back suction airflow ports 255 are connected to form a back suction airflow channel. The wastewater tank 22 and the dust collection bag 23 are connected through the back suction airflow channel. The solid waste back suction channel and the back suction airflow channel are arranged horizontally side by side at the same height. The solid waste back suction port 254 is also provided with a first flip-top baffle 256 that can flip upward with the back suction airflow. The back suction airflow port 255 is provided with a second flip-top baffle 257 that can flip upward with the back suction airflow. The dry-wet separation installation side plate 253 is also provided with an electromagnetic push rod mechanism 26 that can prevent the first flip-top baffle 256 or the second flip-top baffle 257 from flipping upward. In this application, when the back-suction fan 24 is not operating, the first flip-top baffle 256 and the second flip-top baffle 257 are in normal condition, respectively blocking the solid waste back-suction port 254 and the back-suction airflow port 255, closing the solid waste back-suction channel and the back-suction airflow channel. When the airflow is back-suctioned, the suction force generated can cause the first flip-top baffle 256 and the second flip-top baffle 257 to flip up, opening the solid waste back-suction channel and the back-suction airflow channel. The electromagnetic push rod mechanism 26 can block the first flip-top baffle 256 or the second flip-top baffle 257 to prevent the first flip-top baffle 256 or the second flip-top baffle 257 from flipping up under the push of the airflow. In the wastewater back-suction system 2, the back-suction process is as follows: at the beginning of the back-suction, the first air collection is carried out. The electromagnetic push rod mechanism 26 works to block the first flip-top baffle 256. The airflow back-suction pushes the second flip-top baffle 257 to flip up and open the back-suction airflow port 255. The back-suction airflow direction is: back-suction fan 24, dust collection bag 23, back-suction airflow port 255, wastewater tank 22, dry and wet separation box 251, and back-suction pipe 21. A negative pressure is formed in the sealed wastewater tank 22, which sucks the dry and wet waste in the wastewater bucket of the floor scrubber 6 into the dry and wet separation box 251. The wastewater leaks directly into the wastewater tank 22 below from the drain hole 252 at the bottom of the dry and wet separation box 251. Solid waste remains in the dry and wet separation box 251, thus achieving the separation of dry and wet waste.During the second air collection, the electromagnetic push rod mechanism 26 works again, blocking the second flip cover baffle 257 and releasing the first flip cover baffle 256. The airflow draws back and pushes the first flip cover baffle 256 to flip up and open the solid waste return suction port 254, switching the air duct. The airflow changes from the return airflow port 255 to the solid waste return suction port 254, sucking the solid waste in the dry and wet separation box 251 into the dust collection bag 23.

[0163] Furthermore, the electromagnetic push rod mechanism 26 is located below the solid waste return suction port 254 and the return airflow port 255, and includes an electromagnetic push-pull rod 261, a rotating connecting rod 262, a transmission rod, and a push rod spring 263. The electromagnetic push-pull rod 261 is movably installed on the back side of the dry and wet separation installation side plate 253. The dry and wet separation installation side plate 253 is provided with a flip-top bottom plate 264 located below the solid waste return suction port 254 and the return airflow port 255. The flip-top bottom plate 264 protrudes into the dry and wet separation area. Outside the back side of the separated mounting side plate 253, one end of the push rod spring 263 abuts against the upper end of the electromagnetic push-pull rod 261, and the other end abuts against the lower end of the flip cover bottom plate 264. The transmission rod includes a first transmission rod 265 and a second transmission rod 266. The second transmission rod 266 is located below the return air intake port 255 and its upper end is connected to the flip cover bottom plate 264. An integrally formed transmission rod fixing part 267 is provided on the side of the second transmission rod 266. The second transmission rod 266 transmits through... The moving rod fixing component 267 is fixedly connected to the electromagnetic push-pull rod 261. The first transmission rod 265 is located below the solid waste return suction port 254 and its upper end is connected to the flip cover bottom plate 264. A rotating shaft 268 is provided on the dry and wet separation installation side plate 253. A rotating shaft hole 2621 is provided in the middle of the rotating connecting rod 262. The rotating connecting rod 262 is rotatably connected to the rotating shaft 268 through the rotating shaft hole 2621 to form a seesaw-type structure. The first transmission rod 265 and the second transmission rod 266 The lower ends are respectively connected to both ends of the rotating connecting rod 262 and move up and down in turn as the rotating connecting rod 262 rotates. The upper ends of the first transmission rod 265 and the second transmission rod 266 are provided with valve catch pins 269 with blocking function. The back sides of the first flip cover baffle 256 and the second flip cover baffle 257 are provided with limiting members 258 that cooperate with the valve catch pins 269. The valve catch pins 269 can penetrate the flip cover bottom plate 264 and move up and down to block or move away from the limiting members 258.In this application, under normal conditions, the electromagnetic push-pull rod 261 is energized, and the push rod spring 263 is compressed. When the electromagnetic push-pull rod 261 is de-energized, it returns to its original downward position. The push rod spring 263 pushes the second transmission rod 266 downward. Simultaneously, one end of the rotating connecting rod 262 connected to the second transmission rod 266 rotates downward, while the other end of the rotating connecting rod 262 tilts upward. The first transmission rod 265 connected to the other end also pushes upward. The valve catch 269 at the top of the first transmission rod 265 will lock the first flip cover baffle 256, preventing the first flip cover baffle 256 from being subjected to load. The solid waste return suction port 254 is opened by the suction of air, and the solid waste return suction channel is closed. The valve pin 269 at the top of the second drive rod 266 will move away from the limiting part 258 of the second flip cover 257 as the second drive rod 266 moves downward, and will not block the second flip cover 257 from flipping up. The second flip cover 257 will then flip up and open the return air intake port 255, opening the return air intake channel for the first air collection, and the dry and wet waste will be sucked back into the dry and wet separation box 251. The sewage will leak from the dry and wet separation box 251 into the sewage tank 22, and the solid waste will be temporarily stored in the dry and wet separation box 251. When the electromagnetic push-pull rod 261 is energized, it moves relative to the second transmission rod 266 and moves it upward. The valve pin 269 on the second transmission rod 266 blocks the second flip cover baffle 257 from flipping up, closing the return air intake port 255 and the return air intake channel. At the same time, the rotating connecting rod 262 moves like a rocker, which drives the first transmission rod 265 downward and releases the first flip cover baffle 256. The first flip cover baffle 256 is pushed up by the airflow, opening the solid waste return intake port 254, opening the solid waste return air intake channel, realizing the switching of the air duct, and performing a second air collection. The filtered solid waste temporarily stored in the dry and wet separation box 251 is then drawn into the dust collection bag 23.

[0164] Furthermore, the bottom plate of the wet-dry separation box 251 is a sloping plate structure 259, and the drain hole 252 is designed as a sloping funnel-shaped structure, which can accelerate the flow of sewage. At the same time, the negative pressure inside the sewage tank 22 can also accelerate the filtration of sewage, thus effectively shortening the action time.

[0165] Furthermore, the sewage tank 22 includes a sewage tank body 221 and a sewage tank cover 222. The sewage tank cover 222 covers the sewage tank body 221 to form a sealed space. The upper part of the sewage tank body 221 is provided with a dry and wet separation box fixing groove 223. The bottom of the dry and wet separation box 251 is detachably installed in the dry and wet separation box fixing groove 223, and the main body of the dry and wet separation box 251 is set inside the sewage tank cover 222. The solid waste back suction port 254 and the back suction airflow port 255 of the sewage tank 22 are set on the side wall of the sewage tank cover 222. The first flip-top baffle 256 is hinged to the solid waste back suction port 254 of the sewage tank cover 222, and the second flip-top baffle 257 is hinged to the back suction airflow port 255 of the sewage tank cover 222. The outer side of the wastewater tank body 221 is provided with a back suction pipe clearance groove 224. A dry / wet waste outlet connector 225 is provided at the upper end of the back suction pipe clearance groove 224. The end of the back suction pipe 21 connects to the dry / wet waste outlet connector 225. A clearance through hole 2511 is provided on the dry / wet separation box 251, through which the dry / wet waste outlet connector 225 extends into the dry / wet separation box 251. Dry / wet waste in the wastewater tank of the floor scrubber 6 can enter the dry / wet separation box 251 through the back suction pipe 21 and the dry / wet waste outlet connector 225. The wastewater tank body 221 is mainly used to store wastewater. The wastewater tank cover 222 mainly seals the wastewater tank 22 and can bear weight and facilitate the placement of air ducts. The dry / wet separation box 251 can be replaced and cleaned to ensure the cleanliness of the wastewater tank 22.

[0166] Furthermore, the sewage tank lid 222 is also equipped with a sewage tank belt handle 226 and a rotatable plastic sewage tank handle 227. The sewage tank lid 222 is also equipped with a sewage tank plastic handle storage position 228 that matches the sewage tank plastic handle 227. By providing two handles, the sewage tank 22 can be easily lifted and lowered. The sewage tank plastic handle 227 can be rotated to stand upright for carrying, or it can be rotated flat and stored in the sewage tank plastic handle storage position 228.

[0167] Furthermore, a first ozone generator 220 is installed inside the sewage tank 22, and the first ozone generator 220 is fixed to the inner wall of the sewage tank cover 222. The first ozone generator 220 can release ozone ions inside the sewage tank 22, thereby deodorizing the sewage tank 22.

[0168] Furthermore, a sewage discharge port 229 communicating with the interior of the sewage tank body 221 is provided at the bottom of the sewage tank body 221. A recessed portable sewage discharge control groove 2210 is provided above the sewage discharge port 229 on the sewage tank body 221. A portable sewage discharge mechanism 27 is also installed at the lower end of the sewage tank body 221. The portable sewage discharge mechanism 27 includes a sewage discharge button 271, a reset rod 272, and a button reset spring 273. The sewage discharge button 271 and the reset rod 272 are both installed in the portable sewage discharge control groove 2210, which can move back and forth. A reset rod 272 passes through the drain button 271 and can move back and forth on the drain button 271. One end of the button reset spring 273 abuts against the portable drain control slot 2210, and the other end abuts against the drain button 271. A drain port transmission rod 274 is also provided above the drain port 229. A drain port reset spring 275 is sleeved on the drain port transmission rod 274. One end of the drain port reset spring 275 abuts against the lower end of the drain port transmission rod 274, and the other end abuts against the bottom surface of the portable drain control slot 2210. The drain port... A drain port sealing ring 276 is also fixed on the transmission rod 274. The drain port sealing ring 276 seals above the drain pipe port 229 and can move away from and open the drain pipe port 229 as the drain port transmission rod 274 moves upward. A through hole is provided at the bottom of the portable drain control slot 2210. The upper end of the drain port transmission rod 274 is movably set and passes through the through hole at the bottom of the portable drain control slot 2210, extending into the portable drain control slot 2210. An inclined groove 2741 is also provided on the drain port transmission rod 274. A drain button 271 is provided on the drain button 271. An inclined plate 2711, adapted to the inclined groove 2741, is movably installed within the inclined groove 2741 and continuously abuts against the upper surface of the inclined groove 2741. During the pressing and moving of the drain button 271 into the portable drain control slot 2210, the inclined plate 2711 moves forward within the inclined groove 2741, continuously pushing the inclined groove 2741 and driving the drain port transmission rod 274 upward along the through hole at the bottom of the portable drain control slot 2210, causing the drain port sealing ring 276 to move away to open the drain pipe port 229. The rear of the inclined plate 2711 is also provided with a latching groove 2712 adapted to the top surface of the inclined groove 2741. When the rear of the inclined plate 2711 enters the inclined groove 2741, the top surface of the inclined groove 2741 engages with the latching groove 2712, forming a mutually abutting fixed structure between the drain button 271 and the drain port transmission rod 274. The side of the drain outlet drive rod 274 is also provided with an inclined surface 2742, and the side of the reset rod 272 is also provided with a triangular block 2721 that is adapted to the inclined surface 2742. The triangular block 2721 is in contact with the inclined surface 2742, and as the reset rod 272 drives the triangular block 2721 to move in the portable drain control slot 2210, the triangular block 2721 can abut against the inclined surface 2742 and push the drain outlet drive rod 274 upward.In this application, the sewage discharge process of the portable sewage discharge mechanism 27 is as follows: Press the sewage discharge button 271 into the portable sewage discharge control slot 2210. As the inclined plate 2711 of the sewage discharge button 271 moves forward, it can push the inclined groove 2741, thereby driving the sewage discharge port transmission rod 274 to move upward, thereby driving the sewage discharge port sealing ring 276 to move upward away from the sewage discharge port 229. The sewage discharge port 229 opens, and the sewage in the sewage tank 22 can be discharged from the sewage discharge port 229. During the pushing process of the drain button 271, both the button reset spring 273 and the drain port reset spring 275 are compressed. When pushed to a certain extent, the rear part of the inclined plate 2711 will enter the inclined groove 2741, and the top surface of the inclined groove 2741 will be locked in the buckle groove 2712. The drain button 271 and the drain port transmission rod 274 will be fixed to each other. The drain button 271 will not reset under the rebound force of the button reset spring 273, and the drain port transmission rod 274 will not reset under the rebound force of the drain port reset spring 275. This keeps the portable drain mechanism 27 in a stable state without manual control, and continuously drains the sewage in the sewage tank 22. After the sewage is completely drained, press the reset lever 272 into the portable sewage control slot 2210. The reset lever 272, through the triangular block 2721, can push the inclined surface 2742, thereby causing the sewage outlet transmission rod 274 to lift slightly. The top surface of the inclined groove 2741 will disengage from the latching groove 2712, and the sewage discharge button 271 and the sewage outlet transmission rod 274 will lose their mutually supporting fixed state. The sewage discharge button 271 will retract and reset under the action of the button reset spring 273, and the sewage outlet transmission rod 274 will also retract and reset under the action of the sewage outlet reset spring 275, causing the sewage outlet sealing ring 276 to move downward to seal the sewage outlet 229. At the same time, the portable sewage discharge mechanism 27 is installed on the sewage tank body 221. During sewage discharge, the entire sewage tank 22 can be lifted out for sewage discharge, making it more convenient and portable to use.

[0169] Furthermore, the drain button 271 is provided with a through hole, and the reset rod 272 moves and passes through the through hole on the drain button 271. The portable drain control slot 2210 is also provided with a reset rod reset spring 277, one end of which abuts against the portable drain control slot 2210, and the other end abuts against the front end of the reset rod 272.

[0170] Furthermore, a limiting base 2743 is provided at the lower end of the sewage outlet transmission rod 274, and the sewage outlet return spring 275 is sleeved on the sewage outlet transmission rod 274, with the lower end of the sewage outlet return spring 275 fixed on the limiting base 2743.

[0171] Furthermore, the drain outlet sealing ring 276 is a retractable, corrugated hose-type structure. The lower part of the drain outlet drive rod 274, the limiting base 2743, and the drain outlet return spring 275 are all housed within the drain outlet sealing ring 276. The upper part of the drain outlet sealing ring 276 is connected to the bottom surface of the portable drain control slot 2210, and the lower part is fixed to the limiting base 2743. During the up-and-down movement of the drain outlet drive rod 274, the drain outlet sealing ring 276 extends and retracts, causing its lower part to move up and down with the limiting base 2743, moving away from or closer to the drain outlet 229. Simultaneously, the drain outlet sealing ring 276 also encloses the limiting base 2743, the drain outlet return spring 275, and the drain outlet drive rod 274, preventing these components from being corroded by sewage.

[0172] Furthermore, a drain cover 2220 is provided at the bottom of the sewage tank body 221, and a drain pipe 229 is provided on the drain cover 2220.
