Description

Technical Field

[0001] This application relates to the technical field of cleaning equipment, and in particular to a wastewater tank and fabric cleaning equipment. Background Technology

[0002] Cleaning fabrics has always been a tedious yet important task in home, commercial, and public environments. Fabrics are widely used in furniture, curtains, carpets, and seating due to their comfort and aesthetic appeal. However, fabrics easily accumulate dust, stains, grease, and bacteria during use.

[0003] Fabric cleaning equipment is widely used in home and commercial environments. These devices are typically equipped with a wastewater tank to collect dirt and wastewater generated during the cleaning process. Over time, the wastewater tank tends to accumulate a lot of impurities, requiring users to manually disassemble and clean it periodically. While this effectively removes stains, it is time-consuming and laborious, increasing the burden on users. Summary of the Invention

[0004] To address the problem of time-consuming and labor-intensive cleaning of impurities inside sewage tanks, this application provides a sewage tank and fabric cleaning equipment.

[0005] The technical solution for a wastewater tank and fabric cleaning equipment provided in this application is as follows: A wastewater tank and fabric cleaning equipment includes a wastewater tank body, an inlet at the top of the wastewater tank body, an outlet pipe at the bottom of the wastewater tank body, a valve on the outlet pipe, a filter frame that slides vertically inside the wastewater tank body, a float plate at the bottom of the filter frame, an installation box on one side of the wastewater tank body, a through groove communicating with the installation box on the side of the wastewater tank body, a filter box placed inside the installation box, a push plate that slides along the length of the wastewater tank body, and a baffle that slides vertically on the side of the filter box near the wastewater tank body.

[0006] By adopting the above technical solution, sewage enters the sewage tank body, and the filter frame can separate impurities in the sewage. As the water level in the sewage tank body gradually rises, the filter frame moves upward under the buoyancy of the float plate. Because the filter frame moves with the change in water level, impurities will not accumulate in specific positions of the filter frame, so that sewage can enter the sewage tank body through the filter frame. When the filter frame moves to abut against the bottom surface of the push plate, the push plate moves towards the direction of the mounting box. The push plate pushes the impurities above the filter frame into the through groove, and at the same time moves the baffle upward, so that the impurities enter the filter box for easy collection. Users only need to remove the filter box for cleaning, which is simple and convenient.

[0007] Preferably, sliders are fixed on both sides of the push plate, and grooves are respectively opened on the opposite inner sides of the sewage tank body. The sliders slide and cooperate with the sewage tank body along the length direction of the sewage tank body through the grooves. A magnetic block is fixed on the inner wall of the groove away from the mounting box, and the magnetic block can attract the sliders.

[0008] By adopting the above technical solution, when the push plate is not subjected to external force, the magnetic block and the slider are attracted to each other, so that the push plate is located on the side away from the mounting box.

[0009] Preferably, the filter box has a limiting groove on its inner side, and the baffle has a limiting block fixed on each side. The limiting block slides vertically with the filter box through the limiting groove. A spring is fixed on the bottom surface of the limiting block, and the bottom end of the spring is fixedly connected to the inner bottom surface of the limiting groove.

[0010] By adopting the above technical solution, the limiting block moves downward under the elastic force of spring one, thereby causing the bottom surface of the baffle to abut against the bottom surface of the filter box.

[0011] Preferably, movable blocks are fixed on both sides of the baffle, and two abutment grooves are opened on the top surface of the mounting box. An abutment rod is installed on the mounting box by sliding vertically through the abutment grooves. The top surface of the abutment rod is in contact with the bottom surface of the movable block. A second magnetic block is fixed on the bottom surface of the abutment rod, and an electromagnet is fixed on the inner bottom surface of the abutment groove. When the electromagnet is energized, it repels the second magnetic block.

[0012] By adopting the above technical solution, when the push plate moves toward the direction close to the mounting box, the electromagnet is energized and works. The second magnetic block moves upward under the repulsive force of the electromagnet. The second magnetic block drives the abutment rod to move upward. The abutment rod abuts against the moving block and pushes the moving block to move upward, thereby causing the baffle to move upward so that the impurities in the sewage tank body can smoothly enter the filter box.

[0013] Preferably, a horizontal plate is fixed to the inner wall of the sewage tank body near the mounting box. A control groove is provided on the bottom surface of the horizontal plate. A control block is installed on the horizontal plate by sliding vertically through the control groove. A reset block is fixed to the side of the control block. A reset groove is provided on the inner wall of the control groove. The reset block slides vertically with the horizontal plate through the reset groove. A second spring is fixed to the top surface of the reset block. The end of the second spring away from the reset block is fixedly connected to the inner top surface of the reset groove. An inclined surface is provided on the bottom surface of the control block. The inclined surface is located on the side of the control block away from the mounting box. An inclined surface is provided on the top surface of the push plate for abutting against the inclined surface. A moving piece is fixed to the top surface of the control block. A fixed piece is fixed to the inner top surface of the control groove. The moving piece and the fixed piece can make electrical contact. The fixed piece is electrically connected to the power supply. The moving piece is electrically connected to the electromagnet.

[0014] By adopting the above technical solution, when the push plate moves to the bottom of the horizontal plate, the second inclined surface and the first inclined surface come into contact with each other, thereby pushing the control block to move upward, so that the first moving plate and the first fixed plate make electrical contact, the electromagnet is energized and works, the baffle moves upward, the push plate continues to move and pushes the impurities into the filter box.

[0015] Preferably, the bottom of the filter box has several filter holes 1, a support plate is fixed inside the mounting box, the bottom surface of the filter box abuts against the top surface of the support plate, the top surface of the support plate has several filter holes 2, the sewage tank body has a through hole 1 near the inner wall of the mounting box, the inner wall of the through hole 1 has a through hole 2 that communicates with the bottom of the mounting box, the inner diameter of the through hole 1 is larger than the inner diameter of the through hole 2, a sealing block is slidably installed in the through hole 1 along its own radial direction, the sealing block can block the through hole 1, and a spring 3 is fixed between the sealing block and the inner wall of the mounting box.

[0016] By adopting the above technical solution, when the pusher plate pushes the impurities and sewage into the filter box together, the sewage flows downward to the bottom of the installation box through filter hole one and filter hole two. Under the pressure of the sewage, the sealing block moves away from the installation box, so that the sewage enters the sewage tank body through through hole one and through hole two. At the same time, the sewage in the sewage tank body cannot enter the installation box through through hole one and through hole two.

[0017] Preferably, the inner bottom surface of the mounting box is provided with a slope three, and the side of the slope three away from the sewage tank body is higher than the side of the slope three close to the sewage tank body.

[0018] By adopting the above technical solution, the setting of inclined surface three makes it easier for sewage in the installation box to enter the sewage tank body through through hole one and through hole two.

[0019] Preferably, the top surface of the mounting box is provided with a clearance groove, a rotating rod is rotatably installed in the clearance groove, a pressure plate is sleeved on the outer periphery of the rotating rod, a torsion spring is sleeved on the outer periphery of the rotating rod, one end of the torsion spring is fixedly connected to the side of the pressure plate, and the other end of the torsion spring is fixedly connected to the inner wall of the clearance groove.

[0020] By adopting the above technical solution, the pressure plate moves downward under the elastic force of the torsion spring and abuts against the top of the filter box, making it difficult for the filter box to detach from the mounting box when no external force is applied.

[0021] A fabric cleaning device includes a body, a clean water tank body installed inside the body, a suction handle installed on the side of the body, and a wastewater tank body installed between the clean water tank body and the suction handle.

[0022] By adopting the above technical solution, the water pump inside the machine body pumps the cleaning solution in the clean water tank to the brush head of the suction handle. The brush head cleans the fabric, and then the mixed wastewater and impurities are sucked into the pipe through the handle, and then enter the wastewater tank body through the inlet of the wastewater tank body.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. When sewage enters the sewage tank, the filter frame separates the impurities in the sewage. As the water level in the sewage tank gradually rises, the filter frame moves upward under the buoyancy of the float plate. Because the filter frame moves with the change in water level, impurities will not accumulate in specific positions on the filter frame, so that sewage can pass through the filter frame into the sewage tank. When the filter frame moves to abut against the bottom surface of the push plate, it moves the push plate toward the mounting box. The push plate pushes the impurities above the filter frame into the through groove, and at the same time moves the baffle upward, so that the impurities enter the filter box for easy collection. Users only need to remove the filter box for cleaning, which is simple and convenient. 2. When the push plate moves toward the direction of the mounting box, the electromagnet is energized and the second magnetic block moves upward under the repulsive force of the electromagnet. The second magnetic block drives the abutment rod to move upward. The abutment rod abuts against the moving block and pushes the moving block upward, thereby causing the baffle to move upward so that the impurities in the sewage tank body can smoothly enter the filter box. 3. After the pusher plate pushes the impurities and sewage into the filter box, the sewage flows downward through filter hole one and filter hole two to the bottom of the installation box. Under the pressure of the sewage, the sealing block moves away from the installation box, so that the sewage enters the sewage tank body through through hole one and through hole two. At the same time, the sewage in the sewage tank body cannot enter the installation box through through hole one and through hole two. Attached Figure Description

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0034] This application discloses a wastewater tank and a fabric cleaning device. (See also...) Figure 1The fabric cleaning equipment includes a body 8, inside which a clean water tank 81 and a wastewater tank 1 are installed. A suction handle 82 is installed on the side of the body 8. The water pump inside the body 8 pumps the cleaning solution in the clean water tank 81 to the brush head of the suction handle 82. The brush head cleans the fabric, and then the mixed wastewater and impurities are sucked into the pipe through the suction handle 82, and then enter the wastewater tank 1 through the inlet 11 of the wastewater tank 1.

[0035] Reference Figure 2 and Figure 3 The sewage tank body 1 has an inlet 11 at the top and an outlet pipe 12 at the bottom, with a valve 13 on the outlet pipe 12. A filter frame 2 is vertically slidable inside the sewage tank body 1, and a float plate 21 is installed at the bottom of the filter frame 2. An installation box 4 is located on one side of the sewage tank body 1, and a through groove 14 communicating with the installation box 4 is opened on the side of the sewage tank body 1. A filter box 5 is placed inside the installation box 4, and a baffle 51 is vertically slidable on the side of the filter box 5 near the sewage tank body 1. A handle 57 is fixed to the top of the filter box 5.

[0036] Reference Figure 3 A push plate 3 is installed inside the sewage tank body 1. Slider blocks 31 are fixed on both sides of the push plate 3. Slide grooves 32 are respectively opened on the opposite inner sides of the sewage tank body 1. The sliders 31 slide and engage with the sewage tank body 1 along the length direction of the sewage tank body 1 through the slide grooves 32. A magnetic block 33 is fixed on the inner wall of the slide groove 32 away from the mounting box 4. The magnetic block 33 can attract the sliders 31.

[0037] When the push plate 3 is not subjected to external force, the magnetic block 33 and the slider 31 are attracted to each other, so that the push plate 3 is located on the side away from the mounting box 4. When the filter frame 2 moves to abut against the bottom surface of the push plate 3, the push plate 3 is moved toward the mounting box 4. The push plate 3 pushes the impurities above the filter frame 2 into the through groove 14, and at the same time moves the baffle 51 upward, so that the impurities enter the filter box 5, so as to facilitate the collection of impurities.

[0038] Reference Figure 4 and Figure 5 The top surface of the mounting box 4 has a clearance groove 49, within which a rotating rod 491 is rotatably mounted. A pressure plate 48 is fitted around the outer periphery of the rotating rod 491. A torsion spring 492 is fitted around the outer periphery of the rotating rod 491. One end of the torsion spring 492 is fixedly connected to the side of the pressure plate 48, and the other end is fixedly connected to the inner wall of the clearance groove 49. Under the elastic force of the torsion spring 492, the pressure plate 48 moves downward and abuts against the top of the filter box 5, making it difficult for the filter box 5 to detach from the mounting box 4 without external force.

[0039] Reference Figure 6 and Figure 7The bottom of the filter box 5 has several filter holes 56. A support plate 41 is fixed inside the mounting box 4. The bottom surface of the filter box 5 abuts against the top surface of the support plate 41. The top surface of the support plate 41 has several filter holes 42. The inner bottom surface of the mounting box 4 has an inclined surface 47. The side of the inclined surface 47 away from the sewage tank body 1 is higher than the side of the inclined surface 47 near the sewage tank body 1. The inner wall of the sewage tank body 1 near the mounting box 4 has a through hole 43. The inner wall of the through hole 43 has a through hole 44 that communicates with the bottom of the mounting box 4. The inner diameter of the through hole 43 is larger than the inner diameter of the through hole 44. A sealing block 45 is slidably installed in the through hole 43 along its own radial direction. The sealing block 45 can block the through hole 43. A spring 46 is fixed between the sealing block 45 and the inclined surface 47.

[0040] When the pusher plate 3 pushes the impurities and sewage into the filter box 5, the sewage flows downward through the filter hole 1 56 and the filter hole 2 42 to the bottom of the mounting box 4. Under the pressure of the sewage, the sealing block 45 moves away from the mounting box 4, so that the sewage enters the sewage tank body 1 through the through hole 1 43 and the through hole 2 44. At the same time, the sewage in the sewage tank body 1 cannot enter the mounting box 4 through the through hole 1 43 and the through hole 2 44.

[0041] Reference Figure 4 and Figure 7 Limiting grooves 52 are respectively formed on the inner sides of the filter box 5. Limiting blocks 53 are fixed on both sides of the baffle 51. The limiting blocks 53 slide vertically with the filter box 5 through the limiting grooves 52. A spring 54 is fixed on the bottom surface of the limiting block 53. The bottom end of the spring 54 is fixedly connected to the inner bottom surface of the limiting groove 52. Movable blocks 55 are fixed on both sides of the baffle 51. Two abutting grooves 61 are formed on the top surface of the mounting box 4. Abutting rod 6 is mounted vertically in the mounting box 4 through the abutting grooves 61. The top surface of the abutting rod 6 is in contact with the bottom surface of the movable block 55. A magnetic block 62 is fixed on the bottom surface of the abutting rod 6. An electromagnet 63 is fixed on the inner bottom surface of the abutting groove 61. When the electromagnet 63 is energized, it repels the magnetic block 62.

[0042] When the push plate 3 moves toward the mounting box 4, the electromagnet 63 is energized and works. The magnetic block 62 moves upward under the repulsive force of the electromagnet 63. The magnetic block 62 drives the abutment rod 6 to move upward. The abutment rod 6 abuts against the moving block 55 and pushes the moving block 55 to move upward, thereby causing the baffle 51 to move upward so that the impurities in the sewage tank body 1 can smoothly enter the filter box 5.

[0043] Reference Figure 6 and Figure 8A horizontal plate 7 is fixed to the inner wall of the sewage tank body 1 near the mounting box 4. A control groove 72 is provided on the bottom surface of the horizontal plate 7, and a control block 71 is mounted on the horizontal plate 7 by sliding vertically through the control groove 72. A reset block 73 is fixed to the side of the control block 71, and a reset groove 74 is provided on the inner wall of the control groove 72. The reset block 73 slides vertically with the horizontal plate 7 through the reset groove 74. A second spring 75 is fixed to the top surface of the reset block 73, and the end of the second spring 75 away from the reset block 73 is fixedly connected to the inner top surface of the reset groove 74. An inclined surface 76 is provided on the bottom surface of the control block 71, located on the side of the control block 71 away from the mounting box 4. An inclined surface 34 is provided on the top surface of the push plate 3 for abutting against the inclined surface 76. A moving piece 77 is fixed to the top surface of the control block 71, and a fixed piece 78 is fixed to the inner top surface of the control groove 72. The moving piece 77 and the fixed piece 78 can make electrical contact. Fixed plate 78 is electrically connected to the power supply, and movable plate 77 is electrically connected to electromagnet 63.

[0044] When the push plate 3 moves to below the horizontal plate 7, the second inclined surface 34 and the first inclined surface 76 come into contact, thereby pushing the control block 71 to move upward, so that the first moving plate 77 and the first fixed plate 78 make electrical contact, the electromagnet 63 is energized and works, the baffle 51 moves upward, the push plate 3 continues to move and pushes the impurities into the filter box 5.

[0045] The implementation principle of a sewage tank and fabric cleaning equipment in this application embodiment is as follows: Sewage enters the sewage tank body 1, and the filter frame 2 can separate the impurities in the sewage. When the water level in the sewage tank body 1 gradually rises, the filter frame 2 moves upward under the buoyancy of the float plate 21. Since the filter frame 2 moves with the position change of the water level, the impurities will not accumulate in a specific position of the filter frame 2, so that the sewage can enter the sewage tank body 1 through the filter frame 2. When the filter frame 2 moves to abut against the bottom surface of the push plate 3, the push plate 3 moves towards the direction close to the mounting box 4. The push plate 3 pushes the impurities above the filter frame 2 into the through groove 14, and at the same time moves the baffle 51 upward, so that the impurities enter the filter box 5, so as to facilitate the collection of impurities.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
