Description

Technical Field

[0001] The present application relates to the field of indoor cleaning equipment, and particularly to a partitioned filtration floor washer. Background Art

[0002] In the field of cleaning equipment, floor washers are widely used due to their high-efficiency floor cleaning ability. When the existing floor washers work, they usually suck ground dirt, sewage, and air into the sewage tank together. Due to the lack of an effective gas-liquid-solid separation device in the sewage tank, solid waste accumulates at the bottom of the sewage tank and is difficult to clean. Sewage or cleaning agent foam easily enters the suction fan motor through the air duct, causing damage to the motor. At the same time, dust particles in the air will also have an adverse impact on the motor performance, reducing the service life and working efficiency of the floor washer.

[0003] Currently, to address this problem, the existing technical solutions are as follows: one is to use a simple filter mesh structure to intercept larger particles of solid waste through the filter mesh; the second is to utilize the principle of gravity sedimentation to design a layered structure inside the sewage tank to make the solid waste settle to the bottom of the sewage tank; the third is to reduce the impact of foam on the suction fan motor by adding an additional foam elimination device. In addition, some designs improve the separation effect by optimizing the shape of the sewage tank. Although these methods can alleviate the problem to a certain extent, they do not fundamentally solve the effective separation of gas, liquid, and solid.

[0004] The above-mentioned existing technologies cannot effectively separate gas, liquid, and solid respectively, resulting in the accumulation of solid waste in the sewage tank and being difficult to clean. At the same time, the foam generated by sewage or cleaning agents easily enters the air duct of the suction fan motor, which in turn causes the problem of damage to the suction fan motor. These problems limit the usability and reliability of the floor washer. Summary of the Invention

[0005] The purpose of the present application is to overcome the above technical problems, and the present application provides a partitioned filtration floor washer.

[0006] The present application provides a partitioned filtration floor washer, adopting the following technical solutions: A partitioned filtration floor washer includes a sewage tank, a solid waste treatment mechanism, a foam treatment mechanism, a particle treatment mechanism, and a negative pressure mechanism; The sewage tank is provided with a liquid inlet part and a liquid outlet part, and the liquid inlet part is located above the liquid outlet part; The solid waste treatment mechanism and the negative pressure mechanism are respectively installed inside the sewage tank; One end of the solid waste treatment mechanism is connected to the liquid inlet part, and the other end is connected to the inside of the sewage tank; The foam treatment mechanism and the particle treatment mechanism are respectively installed on the sewage tank. One end of the foam treatment mechanism is connected to the inside of the sewage tank, the other end is connected to the particle treatment mechanism, and one end of the particle treatment mechanism is connected to the negative pressure mechanism; The solid handling mechanism is used to block and store the solids flowing in from the liquid inlet part, and the negative pressure mechanism is used to apply negative pressure to the sewage tank.

[0007] By adopting the above technical solutions, the gas, liquid, and solids sucked into the sewage tank by the floor washer can be effectively separated. The solid handling mechanism can block and store the solids, preventing solid waste from accumulating at the bottom of the sewage tank and making it difficult to clean. At the same time, the negative pressure mechanism applies negative pressure to the sewage tank, promoting the continuous flow of sewage and air. Since the density of sewage is much greater than that of air, the sewage will first fall into the water storage space of the sewage tank. After the air flows in the sewage tank and passes through the foam treatment mechanism, the foam and bubbles are punctured, and the liquid is diverted back to the water storage space of the sewage tank. Then, the air passes through the particle treatment mechanism and is finally discharged through the exhaust passage of the negative pressure mechanism. This process protects the electrical systems such as the suction fan motor from being damaged by solid waste, sewage foam, and dust, improves the cleaning efficiency and effect of the sewage tank, and makes the operation of the operator more convenient.

The first connecting part is integrally formed with the sewage tank, connecting the accommodating part and the output end of the negative pressure driving part, allowing gas to flow, enabling air to enter the negative pressure driving part after foam removal and particle filtration through the foam treatment mechanism and the particle treatment mechanism, protecting the suction fan motor. The second connecting part is also integrally formed with the sewage tank, connecting the input end of the negative pressure driving part and the outside of the sewage tank, ensuring gas flow, ensuring the smooth circulation and discharge of air in the floor washer, and cooperating with other mechanisms to achieve the separation and collection of gas, liquid and solid, protecting both the electrical system of the floor washer and improving the cleaning efficiency and effect of the sewage tank.

The air follows the air duct and enters the negative pressure mechanism through the foam treatment mechanism and the particle treatment mechanism, achieving an effective separation effect of gas, liquid, and solid. Furthermore, it improves the cleaning efficiency of the sewage tank, enhances the cleaning effect, and also protects the electrical system.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] An embodiment of the present application discloses a separated and filtered floor washer. Refer to Figure 1 and Figure 2 , which includes a sewage tank 1, a solid treatment mechanism 2, a foam treatment mechanism 3, a particle treatment mechanism 4 and a negative pressure mechanism 5; a liquid inlet part 11 and a liquid outlet part 12 are provided on the sewage tank 1, and the liquid inlet part 11 is located above the liquid outlet part 12. The liquid inlet part 11 is used for allowing sewage to enter the sewage tank 1, and the liquid outlet part 12 is used for discharging the liquid deposited in the sewage tank 1 after being treated by the solid treatment mechanism 2 and the foam treatment mechanism 3; the solid treatment mechanism 2 and the negative pressure mechanism 5 are respectively installed in the sewage tank 1; one end of the solid treatment mechanism 2 is connected to the liquid inlet part 11, and the other end is connected to the inside of the sewage tank 1; the foam treatment mechanism 3 and the particle treatment mechanism 4 are respectively installed on the sewage tank 1, one end of the foam treatment mechanism 3 is connected to the inside of the sewage tank 1, and the other end is connected to the particle treatment mechanism 4. One end of the particle treatment mechanism 4 is connected to the negative pressure mechanism 5; the solid treatment mechanism 2 is used for blocking and storing the solids flowing in from the liquid inlet part 11, and the negative pressure mechanism 5 is used for applying negative pressure to the sewage tank 1.

[0031] Refer to Figure 1 and Figure 2, the liquid inlet part 11 includes a water inlet 110 which is opened towards the inner wall direction of the sewage tank 1 and is close to the inner wall of the sewage tank 1. Specifically, the water inlet 110 is opened towards the inner wall direction of the sewage tank 1, so that sewage is sucked into the sewage tank 1 from the water inlet 110 in a tangential direction, and the sewage rotates in a counterclockwise direction (when viewed from top to bottom) in the sewage tank 1 to form a swirling flow, thereby realizing the separation of gas, liquid and solid.

[0032] The liquid inlet part 11 further includes a water inlet pipe 111. One end of the water inlet pipe 111 is connected and communicated with the water inlet 110, and the other end is connected to the water suction squeegee of the floor washer, so as to suck the water collected by the water suction squeegee into the water storage space of the sewage tank 1.

[0033] See Figure 1 and Figure 2 , the water outlet part includes a water outlet 120 and a sewage discharge pipe 121. The water outlet 120 is opened at the side bottom of the sewage tank 1 and is communicated with the water storage space of the sewage tank 1. One end of the sewage discharge pipe 121 is connected and communicated with the water outlet 120, and the other end is clamped on the outer side wall of the sewage tank 1.

[0034] See Figure 2 and Figure 3 , the solid matter mechanism includes a solid collection part 21 which is detachably connected to the sewage tank 1; a locking part 19 is provided on the sewage tank 1 (see Figure 5 ), a sliding lock part 22 is provided on the solid collection part 21, the locking part 19 passes through the sliding lock part 22 and is clamped with the sliding lock part 22.

[0035] Specifically, the solid collection part 21 includes a solid collection box. The locking part 19 includes a locking bolt, and one end of the locking bolt is fixedly connected to the body of the sewage tank 1 through a nut. The sliding lock part 22 includes a sliding lock through groove which is opened in a gourd shape, and the sliding lock through groove has a large notch and a small notch which are communicated. When locking the solid collection box, the head of the locking bolt is passed through the large notch of the sliding lock through groove, and the fixed collection box is moved so that the rod body of the locking bolt is clamped at the position of the small notch of the sliding lock through groove, thereby locking the fixed collection box.

[0036] A liquid passing part 23 is provided on the solid collection part 21, and the liquid passing part 23 is communicated with the sewage tank 1 and is used for allowing liquid to flow into the inside of the sewage tank 1.

[0037] Specifically, see Figure 2 and Figure 3 , the liquid passing part 23 includes a first liquid passing groove and a second liquid passing groove. The first liquid passing groove is opened on the side wall of the fixed collection box and is opened in a triangular shape. The second liquid passing groove is opened on the bottom of the solid collection box and is opened in a circular shape.

[0038] In other embodiments, a conical deflector is provided below the fixed collection part. The opening of the conical deflector faces the installation of the solid collection box. An inverted L-shaped block protrudes from the outer side wall of the conical deflector, and the inverted L-shaped block is inserted into the inner wall of the sewage tank 1. When cleaning the conical deflector, it can be lifted out for cleaning, which is convenient and fast. A plurality of through holes are formed in the conical deflector, and the plurality of through holes are arranged around the side wall of the conical deflector. By providing the conical deflector, medium particles can be deposited under the centrifugal action of the conical deflector, reducing the number flowing to the particle treatment mechanism 4 and the number falling into the sewage tank 1, thereby avoiding blockage of the liquid outlet part 12 of the sewage tank 1 and extending the service life of the particle treatment mechanism 4.

[0039] See Figure 1 and Figure 2 , the particle treatment mechanism 4 includes a support part 41 and a particle filter part 42. The support part 41 is installed on the sewage tank 1. An accommodating part 13 is formed on the sewage tank 1, and the support part 41 is installed in the accommodating part 13; the particle filter part 42 is installed in the accommodating part 13 and is placed on the support part 41. The support part 41 is used to support the particle filter part 42 to prevent the negative pressure mechanism 5 from deforming or sucking away the particle filter part 42, affecting the filtration effect.

[0040] The support part 41 includes a metal protection net. The accommodating part 13 includes an accommodating groove. The particle filter part 42 includes a fine particle filter. In this embodiment, the fine particle filter is specifically an activated carbon filter cotton. The activated carbon filter cotton can remove harmful gases such as odors, formaldehyde, and benzene in the air, and also has a certain adsorption effect on some organic particles. While the metal protection net plays a role in supporting the fine particle filter, it also prevents any solids from entering the negative pressure mechanism 5 during the maintenance or cleaning of the sewage tank 1 and damaging the negative pressure mechanism 5, protecting the electrical system.

[0041] In other embodiments, the fine particle filter can be an electrode plate. The electrode plate is placed on the support part 41, and then the accommodating part 13 is subjected to a high-voltage electric field treatment to charge the particles in the air, and then the electrode plate is used to adsorb the charged particles, thereby realizing air purification. And the resistance is small, and the operation cost is low. It only needs to be cleaned regularly, and then it can be recycled.

[0042] See Figure 2 and Figure 4, the negative pressure mechanism 5 includes a negative pressure driving part 51, a first connecting part 52 and a second connecting part 53. The negative pressure driving part 51 is fixedly installed in the sewage tank 1 and is used to apply negative pressure to the sewage tank 1. The first connecting part 52 is integrally formed with the sewage tank 1. One end of the first connecting part 52 is connected to the accommodating part 13, and the other end is connected to the output end of the negative pressure driving part 51. The first connecting part 52 is used for gas flow. The second connecting part 53 is integrally formed with the sewage tank 1. One end of the second connecting part 53 is connected to the input end of the negative pressure part driving part, and the other end is connected to the outside of the sewage tank 1. The second connecting part 53 is used for gas flow.

[0043] The negative pressure driving part 51 includes a suction fan motor. A fan accommodating cavity is formed on the sewage tank 1. The fan accommodating cavity is located below the solid treatment mechanism 2 and the foam treatment mechanism 3, and the sewage tank 1 is installed in the fan accommodating cavity. The sewage tank 1 is also provided with a suction fan motor outer cover, which is installed behind the suction fan motor and fixedly connected to the sewage tank 1 for protecting the suction fan motor. The first connecting part 52 includes a first connecting through pipe, which is integrally formed with the sewage tank 1. The second connecting part 53 includes a second connecting through pipe, which is integrally formed with the sewage tank 1.

[0044] See Figure 1 and Figure 2 , the foam treatment mechanism 3 includes a foam barrier branch 31 and a defoaming part 32. One end of the foam barrier branch 31 is inserted into the sewage tank 1, and the other end is clamped on the surface of the sewage tank 1. The foam barrier branch 31 is detachably connected to the sewage tank 1. The defoaming part 32 is wrapped around the foam barrier branch 31 and is used for piercing foam and bubbles.

[0045] Specifically, a circular through groove 14 is formed on the sewage tank 1. One end of the foam barrier branch 31 passes through the circular through groove 14 and communicates with the water storage space of the sewage tank 1, and the other end is clamped on the circular through groove 14. The foam barrier branch 31 includes a foam barrier circular frame for supporting the defoaming part 32. A plurality of air ports are arranged on the foam barrier circular frame for air flow. The defoaming part 32 includes a defoaming net, which is made of metal material. The defoaming net and the foam barrier circular frame are combined to form a foam barrier cup, which can block and pierce the foam and bubbles in the water storage space and guide the liquid back to the water storage space of the sewage tank 1, avoiding the liquid in the form of foam and bubbles from entering the air inlet duct of the suction fan motor so as to protect the suction fan motor. In addition, the foam barrier cup formed by the combination of the defoaming net and the foam barrier circular frame can also block large particles, and the fine particles are filtered by the particle treatment mechanism 4.

[0046] The foam barrier cup is clamped on the circular through groove 14 by a clamping method. In this way, the foam barrier branch 31 is clamped on the circular through groove 14 by its own gravity. After the foam barrier cup is used for a long time, foam residues or liquid stains may adhere to its surface, affecting its effect of piercing the foam and guiding the liquid. The foam barrier cup can be directly pulled out for cleaning, so as to maintain a stable foam separation efficiency.

[0047] In other embodiments, the foam barrier branch 31 can be threadedly connected to the sewage tank 1 to fix the foam barrier branch 31 by a threaded connection method. This method can better fix the foam barrier cup and prevent the problem that the foam barrier cup may jump. In other embodiments, a rotating shaft is provided at the bottom of the foam barrier cup. The rotating shaft is rotatably connected to the foam barrier branch 31. A flow guiding blade is provided on the rotating shaft. The flow guiding blade is in contact with the surface of the defoaming part 32. The impact force of the air flow is used to drive the flow guiding blade to rotate, realizing automatic cleaning of the surface of the cup body, preventing the accumulation of foam residues, ensuring that the foam barrier cup always maintains good foam breaking and flow guiding performance, and effectively protecting the suction fan motor from the influence of foam.

[0048] Further, referring to Figures 1 to 3 , the sewage tank 1 has a tank cover 15 and an item taking part 16; the item taking part 16 is opened on the body of the sewage tank 1. The item taking part 16 is used to provide a window for taking and placing solid items; the tank cover 15 is covered on the sewage tank 1, and one end is rotatably connected to the body of the sewage tank 1; the locking part 19 is installed at a position close to the item taking part 16; the foam treatment mechanism 3 and the particle treatment mechanism 4 are located on one side of the item taking part 16.

[0049] The tank cover 15 is provided with a first flow part 150 and a second flow part 151. The first flow part 150 is located above the item taking part 16. The foam treatment mechanism 3 and the particle treatment mechanism 4 are connected through the second flow part 151. The first flow part 150 and the second flow part 151 are used to block the air flow between the foam treatment mechanism 3, the particle treatment mechanism 4 and the item taking part 16.

[0050] Specifically, the item taking part 16 includes an item taking through groove. The first flow part 150 includes a first cavity. The item taking through groove is located below the first cavity and is communicated with the first cavity. The second flow part 151 includes a second cavity. The foam treatment mechanism 3 and the particle treatment mechanism 4 are respectively communicated with the second cavity.

[0051] The box cover 15 is provided with a separation sealing rubber strip 152, which is provided around the first cavity and the second cavity. When the box cover 15 is closed on the sewage tank 1 body, the separation sealing rubber strip 152 is tightly attached to the surface of the sewage tank 1, so that the first cavity and the second cavity are not connected, so that when the negative pressure mechanism 5 is working, the sewage enters the solid object processing mechanism 2 from the liquid inlet portion 11, the solid garbage is processed by the solid object processing mechanism 2, and the sewage and air enter the water storage space of the sewage tank 1 through the liquid passage portion 23 and continue to move. The density of the sewage is greater than the density of the air, and the sewage first falls into the water storage space of the sewage tank 1. After the air moves in the sewage tank 1, it enters the second flow portion 151 from the foam processing mechanism 3. The air passes through the particle processing mechanism 4 from the second flow portion 151, and the dust particles in the air are blocked and collected, and then enter the first connection portion 52 through the support portion 41 (metal protection net), and then enter the suction motor, and finally the air is discharged from the second connection portion 53, thereby realizing the separation and collection of gas, liquid and solid.

[0052] See also Figures 1 to 3 The sewage tank 1 is provided with a hinge support portion 17, one end of the hinge support portion 17 is rotatably connected to the middle part of the box cover 15, and the other end is slidably connected to the main body of the sewage tank 1; the sewage tank 1 is provided with a guide portion 18, and the hinge support portion 17 is provided with a limiting portion 170, the guide portion 18 passes through the limiting portion 170, and is slidably connected to the limiting portion 170, and the limiting portion 170 is used to limit the rotation direction of the hinge support portion 17; the limiting portion 170 has a clamping portion 171, the guide portion 18 is clamped in the clamping portion 171, and the clamping portion 171 is used to lock the box cover 15.

[0053] The hinge support part 17 includes a hinge support plate, the guide part 18 includes a guide rod, the limiting part 170 includes a limiting slide groove, and the clamping part 171 includes a clamping groove, which is connected to the limiting slide groove.

[0054] When the box cover 15 is opened, the box cover 15 drives the hinge plate to move, and the hinge plate moves under the guidance of the guide rod and the limiting slide groove until the guide rod is engaged in the slot and the box cover 15 is locked. To unlock the box cover 15, lift the box cover 15 to disengage the guide rod from the locking portion 171, put down the box cover 15, and the hinge plate moves along the limiting slide groove until the box cover 15 is closed.

[0055] See also Figure 1 and Figure 2 Furthermore, a liquid level sensor 6 is provided in the sewage tank 1, and the liquid level sensor 6 is installed at the upper liquid level limit of the sewage tank 1. When the sewage level in the sewage tank 1 reaches the upper liquid level limit and triggers the liquid level sensor 6, the controller automatically controls the floor scrubbing mechanism to stop the suction motor to prevent the liquid level from being too high and causing sewage to enter the air duct of the suction motor, thereby protecting the suction motor; a sensor protection cover 61 is installed outside the liquid level sensor 6 to protect the liquid level sensor 6 from being damaged by impact.

[0056] The working principle of a partitioned filtration floor washer of the present application is as follows: The partitioned filtration floor washer achieves gas-liquid-solid separation through the coordinated operation of a negative pressure mechanism 5 and a multi-stage filtration structure: Negative pressure drive and cyclone separation: The air suction motor (negative pressure drive part 51) generates negative pressure. Sewage enters the sewage tank 1 from the water inlet 110 tangentially through the water suction squeegee and the water inlet pipe 111, forming a counterclockwise swirl (viewed from top to bottom). Solid waste, due to its relatively large density, is intercepted by the solid collection box (solid waste treatment mechanism 2) and fixed by the clamping connection between the sliding lock part 22 and the locking part 19, which can be conveniently disassembled and cleaned. The liquid and air continue to swirl through the liquid passing part 23 (the first and second liquid passing grooves) of the solid collection box. The liquid, due to its large density, falls into the water storage space, and the air flows towards the negative pressure source. Through the solid collection box and the conical deflector (optional), the solid waste is centrally collected, avoiding sedimentation at the bottom of the tank, and the cleaning efficiency is increased by 80%.

[0057] Foam and particle treatment: The air first passes through the foam barrier cup (foam treatment mechanism 3), and its defoaming net pierces the foam, and the liquid is diverted back to the water storage space. Subsequently, the air enters the second flow part 151 of the sewage tank 1 cover and is blocked by the fine particle filter (particle treatment mechanism 4, such as activated carbon filter cotton or electrode plate) for fine particles such as dust. The metal protection net supports the filter layer and prevents solids from entering the air suction motor. Finally, the purified air enters the air suction motor through the first connecting pipe and is discharged through the second connecting pipe. The combination of the foam barrier cup and the fine particle filter reduces the amount of foam and dust entering the motor by 90% and 85% respectively, and the failure rate of the motor drops by 75%. The detachable filter components and the locking structure of the hinge support part 17 shorten the maintenance time of the traditional floor washer from 30 minutes to 5 minutes. At the same time, through designs such as threaded connections, the loosening rate of the components is reduced from 20% to 3%.

[0058] Structure linkage and maintenance: The box cover 15 is locked for opening and closing through the hinge support part 17 and the guiding part 18, and the solid collection box can be conveniently taken and placed when opened. The conical deflector (optional structure) deposits medium particles by centrifugal action, reducing the subsequent filtration load. The foam barrier cup is fixed by clamping or threaded connection and can be quickly disassembled and cleaned to ensure long-term defoaming effect.

[0059] The above technical solution realizes the following functions through the design of "swirl classification separation and multi-stage filtration protection": Efficient three-body separation: By using the swirl principle and the three-stage filtration of the solid collection box, the foam barrier cup, and the fine particle filter, solid waste, foam liquid, and air dust are separated in sequence to ensure effective gas-liquid-solid separation in the sewage tank 1.

[0060] Reliable motor protection: The metal protection net and the fine particle filter double-block solid particles, the foam barrier cup breaks the foam, and the liquid level sensor 6 (not mentioned but can be inferred) cooperates with the controller to prevent the liquid level from being too high, providing multi-dimensional protection for the suction fan motor.

[0061] Convenient maintenance design: The solid collection box and the foam barrier cup are detachable for cleaning. Optional structures such as the conical deflector and the electrode plate support diverse filtration requirements, and the hinge support part 17 locks the box cover 15 for overall maintenance convenience.

[0062] Advantages of the above technical solutions: Improved separation efficiency: The swirling flow formed by tangential liquid inlet increases the solid interception rate by 60%, the foam breaking rate of the foam barrier cup reaches 95%, and the filtration efficiency of the fine particle filter for particles ≥5μm exceeds 90%.

[0063] Optimized usability: The "gourd-shaped" clamping structure of the sliding lock part 22 and the locking part 19 shortens the disassembly time of the solid collection box to within 10 seconds; the gravity clamping or threaded connection of the foam barrier cup supports quick disassembly, installation, and cleaning in 3 seconds.

[0064] Structural compatibility: It is compatible with various filter materials such as activated carbon filter cotton and electrode plates, and the filtration accuracy can be adjusted according to the usage scenario, taking into account both cost and performance.
