Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a convenient dual-mode cleaning device. Background Technology

[0002] Currently, with people's increasing demands for environmental hygiene, carpet cleaning has become an indispensable part of modern homes, businesses, and offices. Suction cleaning equipment, as a cleaning tool combining water spraying and wastewater recycling, has gradually become an important part of the cleaning industry due to its high cleaning efficiency. It sprays water or cleaning solution, scrubs stains, and uses strong suction to suck wastewater and dust into a wastewater tank. This not only improves cleaning efficiency but also effectively removes moisture after cleaning, preventing carpets from remaining damp for extended periods and preventing the growth of bacteria and mold, making it an important tool for home cleaning. While current suction cleaning equipment on the market can complete basic cleaning tasks, it still has the following shortcomings in practical applications:

[0003] First, existing cleaning equipment typically relies on a built-in clean water tank as its cleaning water source, limiting the flexibility of water source selection. Due to the limited capacity of the built-in tank, frequent tank replacements are necessary for large-scale or prolonged cleaning operations, reducing cleaning efficiency and increasing operational burden. Second, the water volume in the clean water tank cannot fully match the actual water demand of the cleaning task. When the water in the tank is not completely used up, operators need to manually remove and empty the remaining water, which is not only time-consuming and labor-intensive but also increases operational complexity. Similarly, wastewater discharge from the wastewater tank also requires manual operation, which is cumbersome and adds extra workload.

[0004] On the other hand, due to the large number of internal parts and complex structure, the equipment generates considerable noise during operation, affecting the user experience. Furthermore, the equipment is large in size and occupies a significant amount of space.

[0005] Therefore, further research and development is needed to solve the technical problems existing in the above-mentioned existing technologies. Utility Model Content

[0006] Therefore, in order to solve the problems existing in the prior art, the purpose of this utility model is to provide a convenient dual-mode cleaning device.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

The main body is equipped with an external water source connection module and an external sewage discharge connection module, used to connect to an external water source and an external sewage discharge system, respectively. The external water source connection module is connected to the clean water tank or the cleaning component via the clean water outlet pipe; the external sewage discharge connection module is connected to the wastewater tank or the cleaning component via the wastewater collection pipe.

[0009] To further explain, the main body includes a support frame and a box mounted on the support frame; the clean water tank and the wastewater tank are spaced apart within the inner cavity of the box frame; the bottom of the clean water tank and the wastewater tank are respectively provided with a clean water drain outlet and a wastewater drain outlet for discharging the remaining clean water or the stored wastewater.

[0010] To further explain, the clean water tank is integrally formed on the front side of the inner cavity of the tank body, and the tank body is provided with a water inlet; the cleaning brush is fixed on the bracket and located below the clean water tank; the wastewater tank is embedded in the inner cavity of the tank body and is spaced apart from the clean water tank.

[0011] Further explanation: A water pump for conveying clean water is provided between the clean water tank and the cleaning components, and the water pump is connected to the clean water outlet pipe; the wastewater tank is connected to a negative pressure device and forms a negative pressure, and the wastewater generated during the cleaning process is sucked back through the wastewater recovery pipe; it also includes a control system; the control system is electrically connected to the water pump, the negative pressure device, the external water source connection module, and the external sewage discharge connection module.

[0012] Further explanation: the control system includes an operation panel located on the rear side of the housing; the external water source connection module includes an external water source connector located on the operation panel, the end of which is located in the inner cavity of the housing and is connected to the clean water tank or cleaning component via a clean water outlet pipe; the external sewage discharge module includes an external sewage discharge connector located on the operation panel, the end of which is located in the inner cavity of the housing and is connected to the sewage tank or cleaning component via a sewage recovery pipe.

[0013] To further explain, the cleaning assembly includes a rotatable cleaning brush and a brush motor for driving the cleaning brush to rotate; the wastewater tank is equipped with a filter screen to block impurities in the wastewater.

[0014] To further explain, the brush motor is fixed on the bracket, the brush motor is connected to the cleaning brush, and is located below the clean water tank and the wastewater tank; the bracket is also provided with a brush cover, which is spaced around the outer periphery of the cleaning brush to prevent wastewater from splashing out.

[0015] To further explain, a connecting column is provided above the cleaning brush disc, and an opening is provided on the side wall of the connecting column to communicate with the sewage recovery pipe. The clean water outlet pipe extends from the top of the connecting column to the interior. Multiple water spray pipes are evenly distributed radially on the bottom surface of the cleaning brush disc, and the water spray pipes are connected to the clean water outlet pipe through a movable adapter.

[0016] To further explain, the side of the water spray pipe facing the surface to be cleaned is provided with multiple nozzles, and the multiple nozzles are distributed at intervals along the axial direction of the water spray pipe.

[0017] To further explain, the bottom surface of the cleaning brush disc is provided with a plurality of cleaning brushes, which are spaced apart from the water spray pipe; the cleaning brush disc is provided with a wastewater recovery tank communicating with the connecting column, and the cleaning brushes are located at the opening of the wastewater recovery tank.

[0018] Compared with the prior art, the beneficial effects of this utility model are at least in the following aspects:

[0019] 1. This utility model, through the design of an external water source connection module and an external sewage discharge interface, allows users to flexibly choose to use the built-in clean water tank and sewage tank, or connect to an external water source and sewage system via the external module, according to actual needs. For example, in large venues requiring continuous cleaning over long periods, the external water source interface can be directly connected to an external water source, avoiding the problem of frequent water replenishment due to the limited capacity of the built-in clean water tank, thus significantly improving work efficiency. In smaller cleaning scenarios, both clean water and sewage tanks can be used. This enhances the practicality and flexibility of the equipment, making it more convenient to use and highly adaptable.

[0020] 2. Furthermore, compared to traditional cleaning equipment, the clean water tank and wastewater tank are inconvenient to operate, especially when the tank capacity is not completely used up. Operators need to manually empty the remaining water or wastewater, which is time-consuming, labor-intensive, and increases operational complexity. This utility model's clean water tank and wastewater tank are both designed with drain outlets, allowing direct discharge of any remaining unused clean water without the need for manual disassembly of the clean water tank. This reduces the operator's burden of manually emptying the water, saves time, and reduces unnecessary workload. Simultaneously, it allows for rapid discharge of wastewater from the wastewater tank, greatly improving the convenience and operational efficiency of the equipment.

[0021] 3. This utility model optimizes the internal layout and structural design of the cleaning equipment, including the positions of the clean water tank and the wastewater tank. Through an integrated design, both tanks are rationally arranged within the same space, saving space and making the equipment more compact, reducing unnecessary structural complexity. The drainage outlet design of the clean water tank and wastewater tank also improves the compactness of the equipment structure. Simultaneously, the rational layout of the brush motor avoids unnecessary structures, further making the overall structure of the equipment more compact, balancing the overall center of gravity, reducing vibration and noise problems caused by instability, and improving the user experience.

[0032] To facilitate understanding of this utility model, the technical solution and advantages of the utility model will be further described in detail below with reference to the accompanying drawings and embodiments. The specific structure and features of this utility model are illustrated by way of example and should not constitute any limitation on this utility model. Furthermore, any of the technical features mentioned below (including implicit or disclosed features), as well as any technical features directly shown or implied in the figures, can be arbitrarily combined or deleted among these technical features to form other embodiments that may not be directly or indirectly mentioned in this utility model. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0033] In the description of this utility model, unless otherwise stated, all components used are conventional components in the prior art, and can be implemented as long as they meet the beneficial effects of this utility model.

[0034] like Figure 1-8 As shown, this utility model provides a convenient dual-mode cleaning device, including a movable main body 1 and a clean water tank 2, a wastewater tank 3, and a cleaning component 4 disposed on the main body 1. The clean water tank 2 is used to store clean water and / or cleaning liquid, and is connected to the cleaning component 4 through a clean water outlet pipe 5, and sprays clean water and / or cleaning liquid onto the surface to be cleaned. The wastewater tank 3 is used to collect and store wastewater generated during the cleaning process, and is connected to the cleaning component 4 through a wastewater recovery pipe 6. The main body 1 is provided with an external water source connection module 7 and an external sewage discharge connection module 8, which are used to connect to an external water source and an external sewage discharge system, respectively. The external water source connection module 7 is connected to the clean water tank 2 or the cleaning component 4 through the clean water outlet pipe 5. The external sewage discharge connection module 8 is connected to the wastewater tank 3 or the cleaning component 4 through the wastewater recovery pipe 6.

[0035] In this embodiment, by designing an external water source connection module and an external sewage discharge connection module, the operator can freely choose to use either a built-in clean water tank or an external water source, as well as a sewage tank or a direct connection to an external sewage system, depending on the scenario. For example, when cleaning at home or in a small area, the user can use the built-in clean water tank, while when cleaning in a large area, the user can connect to an external water source through the external water source interface; similarly, the external sewage discharge interface can be directly connected to an external sewage system, reducing the inconvenience of frequent sewage discharge.

[0036] For example, an external water source can be connected via a simple hose or rigid pipe, such as a direct connection to a household water pipe, or via a mobile water truck or bucket. This allows for continuous cleaning over extended periods. The drain outlet can be directly connected to the ground sewer or sewage network, minimizing interruptions and inconvenience during the cleaning process. Generally, the external drainage system is also equipped with a negative pressure device. Furthermore, the external drain outlet can be connected to the sewage network via a quick-connect coupling or to the equipment via a dedicated drain pipe, ensuring rapid and unobstructed discharge of wastewater.

[0037] Inside the device, the connection between the clean water tank and the external water source can be switched via a valve, allowing users to choose between an internal or external water source as needed. For example, a valve can be installed on the device, which users can manually or automatically adjust to control whether to use water from the internal clean water tank or connect to an external water source.

[0038] Specifically, the main body 1 includes a support 11 and a housing 12 mounted on the support 11; the clean water tank 2 and the wastewater tank 3 are spaced apart within the housing 12; the bottom of the clean water tank 2 and the wastewater tank 3 are respectively provided with a clean water drain outlet 21 and a wastewater drain outlet 31 for discharging remaining clean water or stored wastewater. The drain outlet design facilitates quick cleaning of residual water after use, improving the ease of operation of the equipment. For example, the clean water drain outlet can be controlled by a valve to ensure that remaining clean water can be discharged quickly; while the wastewater drain outlet is connected to an external sewage system through a pipe, allowing users to easily discharge wastewater to the external drainage pipe through a quick-connect interface. The wastewater tank 3 is equipped with a filter screen 33 to block impurities in the wastewater.

[0039] In further detail, the main body 1 also includes casters 13 located below the bracket 11 and a handle 14 located on the rear side of the housing 12, so as to facilitate the operator to push the cleaning equipment.

[0040] Specifically, the clean water tank 2 is integrally formed on the front side of the inner cavity of the tank body 12, and the tank body 12 is provided with a water inlet 22 for easy addition of clean water; the cleaning brush 41 is fixed on the bracket 11 and located below the clean water tank 2; the wastewater tank 3 is embedded in the inner cavity of the tank body 12 and spaced apart from the clean water tank 2; the tank body 12 also includes a cover 121 that can be opened and closed above the clean water tank 2 and the wastewater tank 3. The clean water tank is integrally formed on the front side of the inner cavity of the tank body, making reasonable use of space and reducing the size of the equipment; while the wastewater tank and the clean water tank are spaced apart, maintaining the compactness of the equipment structure and ensuring the effective recycling and storage of wastewater.

[0041] Optionally, a water pump 23 for conveying clean water is provided between the clean water tank 2 and the cleaning component 4, and the water pump 23 is connected to the clean water outlet pipe 5; the wastewater tank 3 is connected to a negative pressure device 32 to form a negative pressure, and the wastewater generated during the cleaning process is sucked back through the wastewater recovery pipe 6; a control system 9 is also included; the control system 9 is electrically connected to the water pump 23, the negative pressure device 32, the external water source connection module 7, and the external sewage discharge connection module 8. The negative pressure device can be a vacuum pump, a blower, or other equipment, providing sufficient suction to suck back the wastewater. Activating the negative pressure device allows the air in the wastewater tank to be discharged outwards through a duct towards the ground or other directions. Simultaneously, the wastewater tank also needs to be equipped with a sealed top cover to ensure that a negative pressure is formed inside.

[0042] Specifically, the control system 9 includes an operation panel 91 located on the rear side of the housing 12; the external water source connection module 7 includes an external water source connector 71 located on the operation panel 91, the end of the external water source connector 71 located in the inner cavity of the housing 12 being connected to the clean water tank 2 or the cleaning component 4 via a clean water outlet pipe 5; the external sewage discharge module includes an external sewage discharge connector 81 located on the operation panel 91, the end of the external sewage discharge connector 81 located in the inner cavity of the housing 12 being connected to the sewage tank 3 or the cleaning component 4 via a sewage recovery pipe 6.

[0043] In this embodiment, the electrical connection between the control system and the water pump, negative pressure device, external water source connection module and external sewage discharge connection module enables the equipment to achieve automated control and adjustment during operation. Users can easily control the working status of various components such as the water pump and negative pressure device through the operation panel, which greatly improves the ease of operation.

[0044] In more detail, the cleaning assembly 4 includes a rotatable cleaning brush disc 41 and a brush disc motor 42 for driving the cleaning brush disc 41 to rotate. Specifically, the brush disc motor 42 is fixed on the bracket 11, the brush disc motor 42 is connected to the cleaning brush disc 41 in a transmission manner, and is located below the clean water tank 2 and the wastewater tank 3; the bracket 11 is also provided with a brush disc cover 43, which is spaced around the outer periphery of the cleaning brush disc 41 to prevent wastewater from splashing out.

[0045] Optionally, a connecting post 44 is provided above the cleaning brush disc 41. The side wall of the connecting post 44 has an opening that communicates with the wastewater recovery pipe 6. The clean water outlet pipe 5 extends from the top of the connecting post 44 into its interior. Multiple water spray pipes 51 are evenly distributed radially on the bottom surface of the cleaning brush disc 41. The water spray pipes 51 are connected to the clean water outlet pipe 5 via a movable adapter 52. The connection of the water spray pipes 51 to the clean water outlet pipe 5 via the movable adapter 52 ensures uniform spraying of the cleaning solution.

[0046] In this embodiment, the transmission method between the brush motor 42 and the cleaning brush 41 can be as follows: the output shaft of the brush motor 42 is provided with an output gear 421, and the outer periphery or end of the connecting column 44 is rotatably sleeved with a rotating gear 46 that meshes with the output gear 421 through a bearing assembly (not shown in the figure). The rotating gear 46 is connected to the cleaning brush 41 and drives the cleaning brush 41 to rotate; the movable adapter 52 is rotatably connected to the outlet of the clean water pipe 5 through a bearing.

[0047] Further details are provided: the side of the water spray pipe 51 facing the surface to be cleaned has multiple nozzles 511, which are spaced apart along the axial direction of the water spray pipe 51. Additionally, the bottom surface of the cleaning brush disc 41 has several cleaning brushes 45, which are spaced apart from the water spray pipe 51. The cleaning brush disc 41 has a wastewater recovery tank 411 communicating with the connecting column 44. The cleaning brushes 45 are positioned at the opening of the wastewater recovery tank 411. The design of the wastewater recovery tank effectively collects wastewater generated during the cleaning process. The cooperation between the cleaning brushes 45 and the opening of the recovery tank allows the cleaning brushes to clean wastewater in real time and improves the wastewater recovery rate during the cleaning process.
