Description

Technical Field

[0001] The invention relates to the field of cleaning equipment, and in particular to an air-to-water system applied to a sweeper. Background Art

[0002] Most sweeping machines on the market currently rely on external water supply systems to provide clean water when performing cleaning work. These sweeping machine products are usually connected to tap water pipes for water supply, and a fixed water pipe system needs to be installed during use. Although this type of water supply method can meet basic cleaning needs, it has high requirements on the user's installation environment, especially in places where space is limited or it is inconvenient to install water pipes, which limits the flexibility of the sweeping machine.

[0003] At the same time, the existing way of treating wastewater after cleaning by sweeping machines is usually through pipe drainage or manual drainage. For equipment that uses pipe drainage, an additional drainage system is often required, and the wastewater in the drainage process is directly discharged into the sewer, failing to recycle the wastewater, resulting in a waste of water resources. Manual drainage requires users to manually handle it regularly, which increases the trouble and maintenance costs during use.

[0004] Since the existing clean water supply and wastewater treatment methods rely on complex installation environments and manual operations, the installation location of the sweeper base station is limited, especially in homes or commercial places. If a suitable installation location cannot be provided, it will affect the normal operation of the sweeper. Users often need to adjust the installation layout of the sweeper according to actual conditions, and even arrange additional water pipes for this purpose, which increases the cost and complexity of use. Summary of the invention

[0005] The present invention provides an air-to-water system for a sweeper, which aims to solve the problem that the existing sweeper relies on water supply from a tap water pipe, and to provide a continuous and stable clean water source for the sweeper's working needs by extracting water from the air.

[0006] To achieve the above object, the technical solution of the present invention is:

[0007] An air-to-water system for a sweeping machine includes an air-to-water system body, including:

[0008] A MOF hygroscopic component, used for adsorbing water molecules in the air, wherein the MOF hygroscopic component comprises an adsorption zone and a desorption zone;

[0009] An adsorption component, the adsorption component is connected to the adsorption zone and is used to introduce external air into the MOF moisture absorption component for adsorption of water molecules;

[0010] a desorption assembly connected to the desorption zone, for introducing high-humidity air parsed from the MOF material in the desorption zone into the water collector assembly;

[0011] The water collector assembly comprises an air inlet, an air outlet and a heat exchanger. The water collector assembly is used to condense the high-humidity air from the desorption fan assembly to generate liquid water for cleaning the sweeper.

[0012] In some preferred embodiments, the MOF moisture absorption component comprises a MOF moisture absorption rotor, and the MOF moisture absorption rotor is divided into the adsorption zone and the desorption zone.

[0013] In some preferred embodiments, the water collector component, the MOF moisture absorption component, the desorption component and the adsorption component are respectively arranged in the first shell, the second shell, the third shell and the fourth shell, and the four shells are arranged in sequence.

[0014] In some preferred embodiments, the first shell, the second shell and the third shell are connected by a central axis, the second shell is arranged between the first shell and the third shell, and the cross-sectional area of ​​the second shell is smaller than the cross-sectional area of ​​the first shell.

[0015] In some preferred embodiments, the desorption component includes a desorption fan component and a heating component connected to the desorption fan component, and the heating component is used to heat the air entering the desorption zone to promote the desorption of water vapor from the MOF material.

[0016] In some preferred embodiments, a wastewater reuse system is further included, and the wastewater reuse system includes a wastewater boiler assembly, a steam fan and a steam duct, and the steam duct is connected to the water collector assembly.

[0017] In some preferred embodiments, the air inlet includes a first air inlet and a second air inlet.

[0018] In some preferred embodiments, the heating component includes a heater, a temperature sensor, a temperature protector and a bracket.

[0019] In some preferred embodiments, the wastewater reuse system also includes a water storage tank, a heating module, a temperature sensor and a temperature protector.

[0020] In some preferred embodiments, the water collector assembly further includes a water outlet, which is used to introduce the liquid water into the water tank of the sweeper.

[0021] The beneficial effects achieved by the present invention are:

[0022] On the one hand, MOFs materials absorb moisture under environmental conditions of 0-45°C and 15-95% RH to provide a clean water source, solving the problem that existing sweepers need to be connected to water pipes and improving environmental adaptability. On the other hand, the desorption temperature of MOFs materials is only 55-65°C, which greatly saves energy compared to 120-140°C of other materials. In addition, the system adopts a compact modular structure design, which is easy to integrate into the sweeper, reduces space occupancy, and improves installation flexibility. In addition, the wastewater is boiled by the heating module to form steam, enters the condensation collector and condenses into clean water, realizing the recycling of wastewater, without the need for additional electricity for cooling, further saving energy.

[0034] like Figure 1 , Figure 2 , Figure 3 As shown, an air-to-water system applied to a sweeper includes an air-to-water system body 1, including:

[0035] A MOF hygroscopic component 2, used for absorbing water molecules in the air, wherein the MOF hygroscopic component 2 comprises an adsorption area 3 and a desorption area 4;

[0036] An adsorption component 5, the adsorption component 5 is connected to the adsorption area 3 and is used to introduce external air into the MOF moisture absorption component 2 for water molecule adsorption;

[0037] A desorption component 6, connected to the desorption zone 4, for introducing the high-humidity air desorbed from the MOF material in the desorption zone 4 into the water collector component 7;

[0038] The water collector assembly 7 comprises an air inlet 13, an air outlet and a heat exchanger. The water collector assembly 7 is used to condense the high-humidity air from the desorption fan assembly 17 to generate liquid water for cleaning the sweeper.

[0039] The MOFs material used in the present invention has excellent water vapor adsorption capacity under different temperature and humidity conditions, can adapt to a wide range of working conditions, and provide a continuous and stable clean water source for the working needs of the sweeper.

[0040] like Figure 4 As shown, the water vapor adsorption capacity under low temperature and low humidity conditions of 5℃ / 35%RH is 0.41g / g, the water vapor adsorption capacity under high temperature and medium low humidity conditions of 35℃ / 45% is 0.47g / g, and the water vapor adsorption capacity under medium temperature and medium humidity conditions of 25℃ / 55% is 0.48g / g. The water vapor adsorption capacity of MOFs material under different temperature and humidity conditions is between 0.4-0.49g / g, the adsorption equilibrium time is 10-40 minutes, and the difference in adsorption capacity after adsorption equilibrium is very small, which can achieve working conditions of temperature 0-45℃ and humidity 15-95%RH.

[0041] The principle of water production by adsorption of air is to desorb water vapor in MOFs porous materials through heat energy, thereby increasing the water content and dew point temperature of the treated air, so that water can be produced in the low dew point range of 5-10℃. The principle of water production by traditional compressor system is to condense water by cooling to a temperature lower than the ambient dew point. For example, at a temperature of 5℃ and humidity / 35%RH and a temperature of 15℃ and humidity / 25%RH, the dew points are -8℃ and -4℃ respectively, and the compressor system will be frosted (frozen) and unable to work to produce water.

[0042] The MOFs material of the air-to-water system of this application uses a hydrogen bond adsorption mechanism for water vapor, and can complete water vapor desorption at 55-65°C. The desorption temperature of other similar adsorption materials such as hygroscopic molecular sieves is 120-140°C, which saves about 100% energy compared to the water-making system of this patent. At the same time, the temperature of thermal desorption is much lower than the boiling water temperature of the hydrothermal synthesis of MOFs, and has almost no effect on the molecular structure, which can meet its stability and service life in product applications.

[0043] See also Figure 3The MOF hygroscopic component 2 includes a MOF hygroscopic rotor, which is divided into the adsorption area 3 and the desorption area 4. A gear 21 adapted to the MOF hygroscopic rotor is provided at one corner of the MOF hygroscopic component 2 for driving the MOF hygroscopic rotor to rotate.

[0044] In some preferred embodiments, the water collector component 7, the MOF moisture absorption component 2, the desorption component 6 and the adsorption component 5 are respectively arranged in the first shell 8, the second shell 9, the third shell 10 and the fourth shell 11, and the four shells are arranged in sequence. This modular structure is compact, improves the system performance and ease of use, and is easy to adapt to the overall layout of the sweeper. By placing the water collector component 7, the MOF moisture absorption component 2, the desorption component 6 and the adsorption component 5 in independent shells, respectively, and installing them in sequence, the overall volume can be reduced, which is convenient for integration into the sweeper. This not only optimizes the internal space layout of the sweeper, but also makes installation and maintenance more convenient, and each component can be disassembled and assembled independently. The socket structure effectively reduces the air flow resistance, improves the efficiency of moisture absorption, desorption and water collection, and thus improves the overall performance of the system.

[0045] See also Figure 3 , the first shell 8, the second shell 9 and the third shell 10 are sleeved by the central axis 12, the second shell 9 is arranged between the first shell 8 and the third shell 10, and the cross-sectional area of ​​the second shell 9 is smaller than the cross-sectional area of ​​the first shell 8. This design enlarges the first shell 8 through the sleeve of the central axis 12, improves the air intake, and enhances the air-to-water efficiency; the second shell 9 has a smaller cross-sectional area, which helps to optimize airflow control and improve adsorption and desorption efficiency. The central axis 12 fixes the shell structure, ensures system stability and component alignment, reduces vibration, simplifies assembly and maintenance operations, and facilitates modular management.

[0046] Specifically, the desorption component 6 includes a desorption fan component 17 and a heating component 18 connected to the desorption fan component 17, and the heating component 18 is used to heat the air entering the desorption zone 4 to promote the desorption of water vapor from the MOF material.

[0047] like Figure 5 As shown, it also includes a wastewater recycling system 19, which includes a wastewater boiler assembly, a steam fan and a steam duct, and the steam duct is connected to the water collector assembly 7. The air-to-water system of the present application can realize the recycling and reuse of sweeping wastewater without wastewater discharge.

[0048] Specifically, the air inlet 13 includes a first air inlet 15 and a second air inlet 16 .

[0049] In one embodiment, the water collector assembly 7 is provided with an air inlet 13 and an air outlet.

[0050] The high-temperature and high-humidity air after desorption of the MOF moisture absorption component 2 enters the inner cavity of the water collector through the air inlet 13 of the water collector component 7, and forms a circulating air channel with the desorption fan component 17 and the heating component 18. The temperature difference between the inner and outer walls of the water collector forms liquid water collection.

[0051] In another way, the condensate collector assembly 7 is provided with two air inlets 13 and one air outlet;

[0052] The high-temperature and high-humidity air after desorption from the MOF desiccant component 2 enters the inner cavity of the water collector through the first air inlet 15 of the water collector component 7, and the steam from the wastewater recycling system 19 enters the inner cavity through the second air inlet 16. The two streams of high-temperature and high-humidity air form a circulating air channel with the desorption fan component 17 and the heating component 18. The temperature difference between the inner and outer walls of the water collector causes the air in the inner cavity to condense into liquid water for collection.

[0053] Preferably, the heating component 18 includes a heater, a temperature sensor, a temperature protector and a bracket. The wastewater reuse system 19 also includes a water storage tank, a heating module 23, a temperature sensor and a temperature protector. The water collector component 7 also includes a water outlet 14, and the water outlet 14 is used to introduce the liquid water into the water tank 20 of the sweeper. The sweeper wastewater reuse system 19, the wastewater source comes from the sewage collected by the sweeper after cleaning, which is stored in the wastewater boiler, and is boiled by the heating module 23 to form steam. The steam enters the condensing water collector component 7 and condenses into clean water for recycling.

[0054] Regarding the electrical connection and circuit part, the relevant elements of this embodiment, such as the heater, temperature sensor, gear transmission and protection device, etc., are all electrically connected to form a complete control circuit for controlling the heating module 23, monitoring the temperature and providing necessary overheating protection. The specific electrical connection method and circuit design should be conventional technical means for those skilled in the art, and can be designed and implemented according to specific needs, without too much elaboration.

[0055] The above is a detailed description of the present invention, the purpose of which is to enable people familiar with the technology in this field to understand the content of the present invention and implement it, and it is not intended to limit the scope of protection of the present invention. The present invention is not limited to the above-mentioned embodiments. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the scope of protection of the present invention.
